Accordingly, the presence of the suction nozzle can be detected by the mark imaging device for imaging the nozzle housing hole 624. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a nozzle stocker that houses a suction nozzle that sucks and holds an electronic circuit component, and an electronic circuit component mounting machine that includes the nozzle stocker, and particularly relates to an improvement in usability of the nozzle stocker.

  Conventionally, it is already known to provide a nozzle stocker in an electronic circuit component mounting machine. The nozzle stocker has a nozzle storage hole. For example, a non-defective nozzle that is the same type and has no abnormalities as the suction nozzle that is currently used for mounting electronic circuit components on the circuit board is stored, and the suction nozzle in use is defective. When it becomes a nozzle, the defective nozzle and the non-defective nozzle are exchanged between the nozzle holding head and the nozzle stocker, and the mounting operation is continued (for example, see Patent Document 1). Alternatively, a plurality of types of suction nozzles are housed in a nozzle stocker and are selectively used according to the type of electronic circuit component mounted on the circuit board (for example, see Patent Document 2).

Further, if there is an attachment position error of the nozzle stocker with respect to the electronic circuit component mounting machine, there may be a problem in the transfer of the suction nozzle between the nozzle holding head and the nozzle stocker. Further, when the suction nozzle is returned to the nozzle stocker, if the suction nozzle is already stored in the planned nozzle storage hole, the suction nozzles may hit each other and be damaged. These are examples of problems that arise when an electronic circuit component mounting machine holds a suction nozzle using a nozzle stocker.

Aspects of the Invention

  The present invention further provides a nozzle stocker and an electronic circuit component mounting machine according to the following embodiments. As with the claims, each aspect is divided into sections, each section is numbered, and is described in a form that cites the numbers of other sections as necessary. This is for the purpose of facilitating understanding of the present invention, and should not be construed as limiting the technical features described in the present specification and the combinations thereof to those described in the following sections. . In addition, when a plurality of items are described in one section, it is not always necessary to employ the plurality of items together. It is also possible to select and employ only some items.

(1) A nozzle stocker that has one or more nozzle storage portions that detachably store suction nozzles that suck and hold electronic circuit components, and is detachable from an electronic circuit component mounting machine. A nozzle stocker provided with a stocker information recording unit for recording stocker information as information.
The stocker information recording unit may be a one-dimensional bar code, a two-dimensional code, a stamped identification code (including at least one of numerals, characters, and symbols), an electronic tag, and the like. In addition, stocker information such as stocker individual identification information and stocker type identification information has already been recorded, or stocker information such as mounting position information and stocker history information on the mounting machine main body is recorded later. Some may already be recorded and another may be recorded later.
The stocker individual identification information includes, for example, a code, a name, and the like in which at least one of numbers, characters, symbols, and the like is combined.
The types of nozzle stockers are classified according to, for example, the shape, dimensions, and number of nozzle storage portions, the shape and dimensions of nozzle stockers, and the like.
The stocker type identification information may be configured by elements for identifying the type of nozzle stocker, such as the shape of the nozzle storage unit, and may be configured by encoded data that represents all of these elements.
An electronic tag usually includes a memory that stores information, a communication circuit, and a logic circuit that connects the memory and the communication circuit, and can record information. The electronic tag includes a built-in or external antenna and communicates with the information receiving apparatus to transmit information. The electronic tag can be referred to as an IC (integrated circuit) with a communication function, a wireless tag, or a non-contact tag, and has one or more of the following characteristics. (A) Non-contact transmission of information is possible, (B) Communication with information receivers using radio waves and electromagnetic waves (including light) as a medium, (C) Obstacles (metal (Ex)), and (D) the data storage capacity is large. Some electronic tags receive information in a non-contact manner and the contents of the memory are rewritten, communicate with the information recording device, receive the information, and record it in the memory.

The communication distance varies depending on the transmission method, and communication can be performed in the range of several millimeters to several meters by selecting the transmission method.
There are various shapes of the electronic tag, for example, label shape, cylinder shape, coin shape, card shape, box shape, stick shape, chip shape, sesame grain shape, etc. The size varies from several tens of millimeters. The tag chip has a chip shape and is a relatively small electronic tag.
Therefore, if information related to the nozzle stocker is recorded on an electronic tag having a large amount of information that can be recorded, it is possible to record a large amount of information as compared with a one-dimensional barcode and a two-dimensional code. It can also be used as a database. In addition, if an apparatus capable of transmitting information by wireless communication is employed, information can be received and read even if the information receiving apparatus does not face the electronic tag. When reading information recorded on a bar code, it is necessary to make the bar code and the bar code reader face each other, which limits reading and requires time. The information can be easily read, and the efficiency of assembly work can be avoided. Furthermore, if an electronic tag capable of writing information is employed, for example, the storage history of the suction nozzle with respect to the nozzle stocker can be recorded, which contributes to the use of the nozzle stocker.
In any case, if a stocker information recording unit is provided in the nozzle stocker, the management of the nozzle stocker is facilitated. For example, if stocker individual identification information is recorded in the stocker information recording unit, even if there are a plurality of nozzle stockers of the same type, the nozzle stocker can be individually identified and stored based on the stocker individual identification information. Acquire information about the suction nozzles that have been collected, accumulate history information for each nozzle stocker, indicate the nozzle stocker held in the electronic circuit component mounting machine using individual identification information, and hold it in the electronic circuit component mounting machine It is possible to confirm whether or not the nozzle stocker that has been used is a nozzle stocker to be held, which makes it easy to use the nozzle stocker and avoids using the wrong nozzle stocker. it can.

By taking an image of the stocker reference mark while the nozzle stocker is held by the electronic circuit component mounting machine, for example, an accurate position of the nozzle stocker can be obtained and an attachment position error can be obtained. Since the relative position of the stocker reference mark with respect to the nozzle storage unit is known, the position error of the nozzle storage unit is obtained from the mounting position error of the nozzle stocker. For example, in the electronic circuit component mounting machine, the nozzle holding head and the nozzle storage unit The positions can be adjusted with high accuracy, and the suction nozzles can be reliably exchanged between them.
If the mounting position error of the nozzle stocker is more than the set amount, the alarm device can be alerted or the display device can display that effect to instruct the operator to re-install the nozzle stocker, It is also possible to instruct inspection of the stocker mounting portion of the stocker or electronic circuit component mounting machine.

For example, if the nozzle information includes the type of suction nozzle, the type of suction nozzle stored in the nozzle stocker can be acquired, or the type of suction nozzle when using the suction nozzle stored in the nozzle stocker Can be confirmed. If the nozzle information includes nozzle individual identification information, the mounting history can be created by associating the suction nozzle with the mounting position of the electronic circuit component on the circuit board. Alternatively, if the suction nozzle is a defective nozzle, it is possible to avoid using the defective nozzle by recording use prohibition information as nozzle information.

If the presence or absence of the suction nozzle in the nozzle storage unit is detected, for example, the suction nozzle is held by the nozzle holding head even though the suction nozzle is already stored in the nozzle storage unit. Damage to the nozzle is avoided. Further, when the suction nozzle is taken out from the nozzle storage portion, if the nozzle storage portion is empty, the extraction operation can be prevented from being performed, and a wasteful operation can be avoided. Alternatively, it is possible to avoid the operation of taking out the electronic circuit component by the nozzle holding head that does not hold the suction nozzle even though the suction nozzle is not accommodated. Furthermore, it is possible to acquire a nozzle storage portion in which no suction nozzle is stored.
The presence / absence of the suction nozzle can also be detected by reading the nozzle information by the nozzle information reading device. However, for example, even if the nozzle information reading device is moved to a preset nozzle information reading position, if the suction nozzle is housed in a phase different from the phase where the information can be read by the nozzle information reading device, There is a possibility that the nozzle information is not read and the suction nozzle is actually stored, but it is not stored.

If the suction nozzle is not housed in the nozzle housing section, the ultraviolet light irradiated from the ultraviolet light irradiation device hits the fluorescent layer and radiates visible light. Since the suction nozzle is not provided with a fluorescent layer, if the suction nozzle is housed in the nozzle housing portion, ultraviolet light hits the suction nozzle but no visible light is emitted. The brightness detected by the visible light detection device differs depending on whether or not the suction nozzle is stored, and whether or not the suction nozzle is stored is detected by comparing the detected value with a set value.

For example, the nozzle stocker is positioned at a height suitable for the exchange of the suction nozzle with the nozzle holding head, or the height suitable for imaging the stocker reference mark and reading the information recorded in the stocker information recording unit. Accordingly, the height control of the nozzle holding head and the height control of the reference mark imaging device can be facilitated, or the height control can be omitted. Even if there are multiple devices that perform some action on the nozzle stocker and it is necessary to adjust the distance to the nozzle stocker when performing the action, it is not essential to provide a height control device for each of these devices, or control Is easier.

When the suction nozzles are held, the heights (positions in the vertical direction) of the suction end faces are different from each other. In this case, the distance between each suction end face of the plurality of suction nozzles and the nozzle stocker is different, and when the suction nozzle is transferred between the nozzle holding head and the nozzle stocker, height control is performed for each of the plurality of suction nozzles. It is necessary, and it is considered that a plurality of suction nozzles are individually held by the nozzle holding head, and the mounting apparatus can hold a plurality of types of nozzle holding heads simultaneously.
If the height of the stocker is changed according to the type of the nozzle holding head, the height of the nozzle holding head when the suction nozzle is exchanged with the nozzle stocker even if the type of the nozzle holding head changes.

If the removal of the suction nozzle by a person is prevented, the person cannot freely remove the suction nozzle from the nozzle stocker, and the configuration of the nozzle stocker (type and position of the suction nozzle stored) depends on the person. Guaranteed not to change. Since the suction nozzle is taken out by the nozzle holding head by the electronic circuit component mounting machine itself in the electronic circuit component mounting machine, the actual configuration is automatically acquired even if the configuration of the nozzle stocker is changed. There is no problem even if the suction nozzle can be taken out.

(30) The nozzle take-out prevention device allows the suction nozzle to be taken out when the nozzle stocker is attached to the mounting machine main body, and prevents the suction nozzle from being taken out when the nozzle stocker is detached from the mounting machine main body. The electronic circuit component mounting machine according to (28) or (29), comprising an off-machine nozzle removal prevention device.

There is no problem even if it is broken.
In some cases, a person can take out the suction nozzle from the nozzle stocker in the electronic circuit component mounting machine. In this case, for example, if an operation that is always performed by a person or an apparatus is detected by the detection apparatus when the nozzle stocker is extracted, it is understood that at least the suction nozzle may have been extracted. It is possible to cope with the removal of the suction nozzle by a person, such as checking whether the configuration of the nozzle stocker has been changed based on that, so that there is no problem even if the person removes the suction nozzle. Can do.
Even when outside the machine, the suction nozzle can be taken out by providing a release device that cancels the suction nozzle removal prevention by the nozzle removal prevention device. The same applies to the manual removal prevention device.

  Various suction nozzles including the suction nozzles 158 and 182 used for mounting are detachably stored in a nozzle stocker as a nozzle storage device. The type of circuit component 25 to be mounted differs depending on the type of nozzle holding head 40, the type and number of suction nozzles used for mounting are also different, the type of nozzle holding head 40, and the circuit component 25 to which the nozzle holding head 40 is mounted. A plurality of types of nozzle stockers that accommodate the types and number of suction nozzles corresponding to the types are prepared, and are selectively attached to the mounting modules 12 and 13 to exchange the suction nozzles with the nozzle holding head. In the present embodiment, the types of nozzle stockers are defined by the diameter, number and arrangement of circular nozzle storage holes whose shape, dimensions, and shape in plan view constituting the nozzle storage portion are different, and at least one of them is different. The nozzle stocker is a different type of nozzle stocker. FIG. 16 and FIG. 22 show nozzle stockers 600 and 602 which are one form of the nozzle stocker.

  Various nozzle stockers including these nozzle stockers 600 and 602 are selectively attached to attachment portions 610 provided in the mounting modules 12 and 13, respectively. As shown in FIGS. 14 and 15, the mounting modules 12 and 13 are each provided with a plurality of attachment portions 610. In each of the mounting modules 12 and 13, a nozzle stocker is attached to at least one of the plurality of attachment portions 610, and a component storage device described later is attached to one. Even if the types of mounting modules are different, the configuration of the mounting portion 610 is the same, and a plurality of types of nozzle stockers including the nozzle stockers 600 and 602 can be selectively mounted to a plurality of types of mounting modules. A plurality of types of nozzle stockers including the nozzle stockers 600 and 602 are collectively referred to as a nozzle stocker 600 and the like. The same applies to the suction nozzles 158 and 182 and the nozzle storage holes 624 and 724 described below.

The nozzle stocker 600 will be described.
Like the suction nozzle 158, the nozzle stocker 600 is configured to accommodate a large number of suction nozzles to which small circuit components 25 are attached. As shown in FIGS. 16 and 17, the nozzle stocker 600 includes a nozzle storage base 620 as a nozzle stocker body or nozzle storage member, and a shutter 622 as a nozzle removal prevention member or nozzle removal prevention member.

  As shown in FIG. 16, the nozzle storage base 620 is provided with a plurality of nozzle storage holes 624, and each of the suction nozzles 158 is stored in a removable manner. Each of these nozzle housing holes 624 constitutes a nozzle housing portion. As shown in FIGS. 16 and 18, the nozzle housing hole 624 is orthogonal to the moving direction of the shutter 622 (vertical direction in FIG. 16) and the shutter moving direction in one plane parallel to the plate surface of the nozzle housing base 620. Are arranged in a state of being arranged at a constant pitch in each direction (left and right direction in FIG. 16). Each of these nozzle housing holes 624 is a stepped hole having a large diameter hole 626 that can accommodate the background forming portion 396 of the suction nozzle 158 and a small diameter hole 628 that can accommodate the suction pipe 362. On the shoulder surface 630 formed between the portion 626 and the small diameter hole 628, a positioning pin 632 as a positioning portion is provided upright. The protruding length of the positioning pin 632 is slightly smaller than the depth of the large-diameter hole 626, and is retracted downward from the surface or upper surface of the nozzle storage base 620. When the suction nozzle 158 is housed in the nozzle housing hole 624, the engagement recess 408 provided in the background forming portion 396 is fitted into the positioning pin 632, and the suction nozzle 158 is prevented from rotating relative to the suction nozzle 158. 158 is stored in the nozzle stocker 600 with a predetermined phase, and the phases of the two-dimensional code 406 and the engagement recess 398 are uniquely determined. The engaging recess 408 constitutes a positioning recess as a positioned portion, and the positioning pin 632 constitutes a positioning projection as a positioning portion, and these constitute a suction nozzle positioning device or a suction nozzle phasing device.

  In the present embodiment, as shown in FIG. 16, the positioning pin 632 is covered by the shutter 622 when the shutter 622 is positioned at the nozzle extraction preventing position, but is covered by the shutter 622 when positioned at the nozzle extraction allowable position. It is provided in a position that is not broken. In the present embodiment, the engaging recess 398 and the two-dimensional code 406 of the suction nozzle 158 are in the state where the suction nozzle 158 is positioned by the positioning pin 632 and stored in the nozzle storage hole 624 at a constant phase. Is provided at a position that is not covered by the shutter 622 regardless of whether the nozzle is at the nozzle removal prevention position or the nozzle removal allowance position. However, this is not indispensable for the two-dimensional code 406 and may be provided at a position that is not covered by the shutter 622 at least in a state where the shutter 622 is positioned at the nozzle extraction allowable position. The positioning pin 632 may also be provided at a position that is not covered by the shutter 622 when the shutter 622 is located at the nozzle removal prevention position.

  The positioning pin 632 has a diameter different from that of the positioning pin 384 that positions the suction nozzle 158 with respect to the nozzle holder 160. In this embodiment, the positioning pin 632 has a larger diameter than the positioning pin 384. Therefore, for example, when the operator stores the suction nozzle 158 in the nozzle stocker 600, the positioning pin 632 is erroneously fitted into the engagement recess 398 into which the positioning pin 384 is fitted, and the suction nozzle 158 is erroneous. The phase is prevented from being stored in the nozzle storage hole 624. The configuration in which the diameters of the two types of positioning pins 384 and 632 are different and the sizes of the engagement recesses 398 and 408 are adjusted to the size thereof constitutes the suction nozzle storage phase instruction means or the erroneous phase storage prevention means. .

  Further, as shown in FIG. 18, a fluorescent layer 634 is provided on each bottom surface of the plurality of nozzle housing holes 624 (the bottom surface of the small-diameter hole portion 628). In the present embodiment, the fluorescent layer 634 is provided by attaching a fluorescent seal to the bottom surface of the nozzle housing hole 624.

It is done. A plurality of guide rods 844 serving as a plurality of guide members are provided on the stocker holding base 764 in the vertical direction, and are fitted to guide portions 846 provided on the elevating member 838 and the apparatus main body 834 so as to be relatively movable. Thereby, the raising / lowering of the raising / lowering member 838 and the stocker holding stand 764 is guided. The guide rod 844 and the guide portion 846 constitute a guide device 848.

  A tension coil spring 860 as an elastic member, which is a kind of biasing device, is disposed between the stocker holding base 764 and the apparatus main body 834, and the stocker holding base 764 is lowered by the biasing of the spring 860. At the same time, the elevating member 838 is lowered. The lower end positions of the stocker holding base 764 and the elevating member 838 are defined by the stroke ends of the pistons 862 and 864 of the air cylinders 830 and 832, respectively.

  The rising end position of the elevating member 838 is defined by the contact member 868 provided at the lower end portion of the guide rod 844 contacting the stopper 870 provided on the apparatus main body 834. In the present embodiment, the stopper 870 is constituted by a bolt screwed in the apparatus main body 834 in the vertical direction, and the rising end position of the elevating member 838 can be adjusted. The rising end position of the stocker holding table 764 is defined by the stopper 872 provided on the stocker holding table 764 coming into contact with the lifting member 838. The stopper 872 is also constituted by a bolt, and the rising end position of the stocker holding base 764 can be adjusted. These stoppers 870 and 872 are stoppers having an adjustment function, and constitute a rising end position adjusting device. The combination of raising and lowering of the raising and lowering member 838 and raising and lowering of the stocker holding base 764 raises and lowers the stocker holding base 764 to three positions and three positions. The lowest position is called the first position, the middle position is called the second position, and the uppermost position is called the third position. The second position and the third position can be adjusted by adjusting the rising end positions of the elevating member 838 and the stocker holding base 764, respectively. In the present embodiment, the stocker holding base 764 is raised to the second position by the operation of the air cylinder 832, and is raised to the third position by the operation of the air cylinders 830 and 832. FIG. 23 shows a state where the stocker holding stand 764 is located at the third position.

  The stocker holding device 760 is moved up and down by the holding device lifting and lowering device 762, so that the nozzle stocker 600 and the like held by the stocker holding device 760 are moved up and down, and the height thereof is the first, second and third positions. Changed to The holding device lifting device 762 is a nozzle stocker lifting device. As described above, the nozzle storage base 720 of the nozzle stocker 602 has a thickness different from that of the nozzle storage base 620 of the nozzle stocker 600, and the height of the nozzle storage base 720 in a state where the nozzle storage base 720 is positioned at each of the first to third positions. Is different from the nozzle storage base 620, but is positioned by raising and lowering the stocker holding base 764 to the first to third positions. The nozzle stocker 600 and the nozzle stocker 602 are both raised and lowered. Called the first, second and third positions.

  The stocker holding stand 764 is always located at the first position (when the nozzle exchange between the nozzle holding head 40 and the nozzle stocker 600 or the like and the imaging of the two-dimensional code 696 or the like is not performed), as will be described later. When the two-dimensional code 696 or the like provided in the nozzle stocker 600 or the like is read (when the image is picked up by the mark image pickup device 178), the suction is performed between the nozzle holding head 40 and the nozzle stocker 600 or the like. When the nozzle 158 or the like is transferred, the nozzle 158 is positioned at the second position or the third position.

  As will be described later, after the suction nozzle 158 and the like receive the circuit component 25 from the component supply device 24, the nozzle holding head 40 is imaged by the component imaging device 50, and the holding position error is corrected. The nozzle holding head 40 is mounted on the wiring board 30 until the nozzle holding head 40 is moved to the component mounting position set on the wiring board 30 after receiving the circuit component 25 as shown in FIGS. In the meantime, the lower surface of the circuit component 25 sucked by the suction nozzle 158 is located within the depth of field of the component imaging device 50 and is positioned so as not to interfere with the circuit component 25 already mounted on the wiring board 30. Be made.

  In the present embodiment, the circuit component 25 held by the suction nozzle 158 of the nozzle holding head 40a is larger than the circuit component 25 mounted by the nozzle holding head 40 capable of holding a maximum of twelve suction nozzles 158, and has a high height during movement. The nozzle holding head 40a is higher, but the lifting stroke L1 at the time of nozzle transfer is the same. Therefore, the lower end position of the nozzle holder 160 at the time of nozzle transfer is higher in the nozzle holding head 40a than in the nozzle holding head 40 capable of holding the twelve suction nozzles 158, and the nozzle transfer position of the nozzle stocker 600 is the nozzle holding head. In the case of 40a, the third position is set (see FIG. 39), and in the case of the nozzle holding head 40 holding the twelve suction nozzles 158, the second position is set (see FIG. 40).

  As shown in FIGS. 41 and 42, in the case of the nozzle holding head 40b, the circuit component 25 to be mounted is larger than the nozzle holding head 40a, and the height of the nozzle holding head 40b during movement is higher than that of the nozzle holding head 40a. The up / down stroke L2 for transferring nozzles is made larger than the up / down stroke L1, and the nozzle stocker 602 is positioned at the second position when the two-dimensional code 736 is imaged, and between the nozzle holder 180 of the nozzle holding head 40b. At the time of delivery of the suction nozzle 182, the suction nozzle 182 is positioned at the third position. The nozzle storage base 720 is thicker than the nozzle storage base 620, and when the nozzle stocker 602 is raised to the second position, which is the imaging position, the upper surface of the nozzle storage base 720 is positioned above the component mounting surface of the wiring board 30. The two-dimensional code 696 is provided at a position lower than the upper surface of the nozzle storage base 720, and is positioned at the same height as the component mounting surface, so that imaging can be performed satisfactorily. 41 and 42 are different from FIGS. 39 and 40 in the reduction ratio with respect to the actual size for convenience of illustration.

  As described above, the height of the nozzle holder 160 and the like in the nozzle transfer varies depending on the type of the nozzle holding head 40, and the height of the nozzle stocker 600 and the like is changed according to the type of the nozzle holding head 40. As a result, for example, the nozzle holding head 40a and the nozzle holding head 40 holding up to twelve suction nozzles 158 can have the same up / down stroke of the nozzle holder 160 in the nozzle exchange, and the up / down control is easy. is there.

  In the present embodiment, the second position and the third position of the stocker holding base 764 and the up / down strokes L1 and L2 when the nozzle holding head 40 receives and transfers the nozzles are set such that the second position is a two-dimensional code 696 or the like by the mark imaging device 178. The height suitable for imaging, that is, the two-dimensional code 696, 736 is at the same height as the component mounting surface of the wiring board 30, and the height at which the two-dimensional code 696 and the like are favorably imaged by the mark imaging device 178 is obtained. The third position is set and adjusted so as to have a height suitable for nozzle transfer. Note that the first position may also be adjusted. The height of the entire holding device lifting device 762 is adjusted by the adjusting device.

  Note that the attachment portion 610 may be different in size, for example, and may be able to cope with a significant change in the type of nozzle stocker.

  In the nozzle stocker 600 or the like, the type and number of suction nozzles 158 corresponding to the type of the nozzle holding head 40 (the type of the wiring board 30 on which the circuit component 25 is mounted by the nozzle holding head 40) are stored. In the electronic circuit component mounting system, the nozzle holding head 40 can store and replace the suction nozzle 158 and the like in the nozzle stocker 600 and the like. In this case, the suction nozzles held by the nozzle holding heads 40 of the mounting modules 12 and 13 are accommodated in the nozzle transport plate 900 as a nozzle transport member shown in FIG. 27 and transported to the mounting modules 12 and 13.

  A description will be given using a nozzle transport plate 900 that transports the suction nozzle 158 as an example. As illustrated in FIGS. 27 to 29, the nozzle transport plate 900 includes a nozzle storage member 912 that stores a plurality of types of suction nozzles 158 and a storage member holding device 914 that holds the nozzle storage member 912. The storage member holding device 914 includes a plate-like holding base 916 that supports the nozzle storage member 912. As shown in FIG. 28, on both sides of the holding base 916 corresponding to the rails 250, 252, 254, and 256 of the wiring board transport device 34, as shown in FIG. A pair of supported portions 917 that are supported by the portions are provided. The nozzle transport plate 900 is supported and transported by the wiring board transport device 34 on the holding table 916 and is held by the wiring board holding device 32.

  The holding table 916 is provided with a positioning device 918 (see FIG. 27) for positioning the nozzle storage member 912 and a fastener 920 (see FIG. 27) as a fixing device for fixing. The positioning device 918 includes two headed pins 922 fixed to the holding base 916 in a direction parallel to one side of the holding base 916 and two engagement notches 924 of the nozzle storage member 912 corresponding thereto. The nozzle housing member 912 is positioned with respect to the holding base 916 by engaging each engagement notch 924 with each of the headed pins 922. In this state, the well-known fastener 920 is manually operated by an operator, whereby the nozzle storage member 912 is fixed to the holding base 916. The nozzle storage member 912 may be positioned and fixed to the holding base 916 by a positioning device and a fixing device having the same configuration as the stocker positioning device 766 and the stocker fixing device 768.

  As shown in FIG. 28, a plurality of reference marks 930 are provided on a surface 928 that is a support surface that supports the nozzle storage member 912 of the holding base 916. In the example shown in the figure, reference marks 930 are provided at two positions separated from each other on a diagonal line of the holding table 916.

  The nozzle transport plate 900 has basically the same configuration and function as the nozzle stockers 600 and 602 described above. The nozzle storage member 912 is configured in the same manner as the nozzle storage base 620 and has a plurality of nozzle storage holes in which a plurality of suction nozzles 158 are stored one by one. The nozzle storage holes are configured in the same manner as the nozzle storage holes 624, and the suction nozzles 158 are positioned by positioning pins 632 and stored at a constant phase, but the number thereof is larger than that of the nozzle stocker 600. Further, a shutter 940 configured in the same manner as the shutter 622 is attached to the nozzle housing member 912 so as to be movable between a nozzle removal prevention position and a nozzle removal permission position. Further, although illustration is omitted, the movement of the shutter 940 is guided by a guide device configured in the same manner as the guide device 680, and the lift from the nozzle storage member 912 is configured in the same manner as the lift prevention device 694. Prevented by lifting device. These nozzle housing holes and the like will be used in the description by using the same reference numerals as those assigned to the components of the nozzle stocker 600.

  The shutter 940 is moved by a shutter moving device 944. The shutter moving device 944 includes an air cylinder 960 (see FIG. 27) which is a kind of fluid pressure cylinder as a driving source. The air cylinder 960 is fixed to the support plate 300. An engaging member 964 is attached to the tip of the piston rod 962 of the air cylinder 960, while an engaging portion 966 that extends downward is provided on the shutter 940. The engagement member 964 is generally a hollow cylindrical member with a bottom, and is slidably fitted to the distal end portion of the piston rod 962. The relative movable range of the engagement member 964 with respect to the piston rod 962 is defined by a relative movement range defining device 972 including a pin 968 fixed to the piston rod 962 and a long hole 970 formed in the engagement member 964. Further, a compression coil spring 974 as an elastic member is disposed between the piston rod 962 and the engaging member 964, and urges the engaging member 964 in a direction to be detached from the piston rod 962. Similarly to the shutter moving device 770, the shutter moving device 944 is common to the shutters provided for the plurality of types of nozzle storage members 912, respectively.

  While the nozzle transport plate 900 is transported by the wiring board transport device 34, the support plate 300 constituting a part of the wiring board holding device 32 is held at the lowered end position (retracted position) by the support plate lifting / lowering device 308. Interference between the shutter moving device 944, the backup pin 302, and the like, and the engaging portion 966, the fastener 920, and the like of the shutter 940 is avoided. After the nozzle conveyance plate 900 is stopped at a predetermined position in the mounting modules 12 and 13, the support plate 300 is raised to the rising end position by the support plate lifting / lowering device 308, whereby the engagement member of the shutter moving device 944 is engaged. 964 faces the engaging portion 966 of the shutter 940 with a small distance.

  In this state, the piston rod 962 of the air cylinder 960 is extended and the engagement member 964 is engaged with the engagement portion 966. The nozzle storage member 912 is moved to the nozzle take-out allowable position against the urging force. The spring 976 corresponds to the spring 668 of the nozzle stocker 600. Thereafter, the piston rod 962 is further extended by a small distance, but this excessive extension is absorbed by the retraction of the engagement member 964 against the biasing force of the spring 974. On the other hand, when the piston rod 962 is contracted, the shutter 940 is moved to the separation preventing position with respect to the nozzle housing member 912 by the bias of the spring 976.

  In the case of the shutter 940, each movement range between the nozzle removal prevention position and the nozzle removal allowance position is defined by the guide pin 682 and the long hole 684 of the guide device 680 that guides the movement of the shutter 940. The shutter 940 also serves to prevent the suction nozzle 158 from falling off the nozzle housing member 912 when the nozzle transport plate 900 is transported.

  There are a plurality of types of nozzle storage members 912 that differ in the number of nozzles stored, the size of the nozzle storage holes, and the like. The same configuration as the nozzle storage base 720 of the nozzle stocker 602 is provided, and a shutter similar to the shutter 722 is provided. An appropriate nozzle storage member 912 is used for transporting the suction nozzle 158 and the like according to the type of the nozzle holding head 40 attached to the mounting module, the type of the nozzle stocker 600, and the like. The holding table 916 has a size that can cope with a significant change in the type of the nozzle conveyance plate 900.

  As described above, the height of the nozzle holding head 40 when the nozzle holding head 40 holds or returns the suction nozzle 158 stored in the nozzle stocker 600 or the like varies depending on the type of the nozzle holding head 40. The nozzle stocker 600 and the like are attached to the stocker holding device 760 and moved up and down by the holding device lifting and lowering device 762, and the height thereof is changed in three stages when the suction nozzle 158 and the like are exchanged with the nozzle holding head 40. However, in the case of the nozzle transport plate 900, since it is moved up and down by the support plate lifting and lowering device 308 of the wiring board holding device 32, the lifting and lowering thereof is performed. The position is determined by raising and lowering the wiring board 30. Therefore, in this embodiment, the nozzle transport plate 900 has a different thickness of the nozzle storage member 912 depending on the type of the nozzle holding head 40, and the nozzle transport plate 900 is moved to the rising end position by the support plate lifting / lowering device 308. The suction nozzle 158 and the like housed in the nozzle housing member 912 are positioned in the nozzle delivery position according to the type of the nozzle holding head 40 in the vertical direction. Although the holding base 916 is common, there are a plurality of types of nozzle storage members 912 having different thicknesses (heights) in addition to the diameter and number of the nozzle storage holes 624, and according to the type of the nozzle holding head 40. A nozzle storage member 912 is attached to the holding table 916 and used for transporting the suction nozzle 158 and the like.

Although the detailed illustration is omitted, the mounting portion 1004 is configured in substantially the same manner as the mounting portion 610, and includes a stocker holding base, a stocker positioning device, a stocker fixing device, and a stocker support member. In addition to being positioned and attached, the energization to the solenoid of the drive device 714 of the lock device 710 is controlled in a state where the nozzle stocker is attached. A lock release control computer 1010 is provided to control energization of the solenoid based on a command or the like input from the input device 1012. The unlock control computer 1010 further controls the imaging device 1014 as an information reading device via a control circuit (not shown) and performs image processing on data obtained by imaging. The imaging device 1014 includes, for example, a CCD camera as an imaging device, and is arbitrarily placed on a stocker holding base on a nozzle stocker 600 or the like attached to the attachment unit 1004 by an imaging device moving device 1016 as an information reading device moving device. Moved to the position. The imaging device moving device 1016 is configured in the same manner as the holding head moving device 44, for example.

  The lock release control computer 1010 instructs the lock release using the input device 1012, and when the image reading device 1014 images the two-dimensional code provided in the nozzle stocker and reads the stocker information, An electric current is supplied to the solenoid, the lock device 710 is unlocked, and the operator can freely open and close the shutter manually to replace the suction nozzle. The unlock control computer 1010 is connected to a host computer to be described later, and transmits information indicating that the lock device 710 has been unlocked and stocker information obtained by imaging a two-dimensional code. As a result, the nozzle stocker whose shutter is unlocked is identified in the host computer, and the lock release information including the individual identification information of the unlocked nozzle stocker and the fact that the lock is released is stored in the lock release information memory. The

The adhesive applicator 1106 is configured, for example, in the same manner as the adhesive applicator described in Japanese Patent No. 3242120, and includes an application nozzle 1108 and a syringe 1110 as an adhesive container. An adhesive 1112, which is a kind of highly viscous fluid, is accommodated in the syringe 1110. If compressed air is supplied from a compressed air supply source (not shown) into the syringe 1110, the adhesive passes through the discharge pipe 1114. It is discharged and applied to the wiring board 30 by a predetermined amount.

  In the adhesive application module, for example, prior to the start of a series of mounting operations on the wiring board 30, the adhesive is discarded and tested, and the adhesive is smoothly discharged from the discharge pipe 1114. At the same time, an appropriate amount of adhesive is applied to the wiring board 30. Therefore, the adhesive application module is provided with a trial hitting device 1120 as an adhesive application device. As shown in FIG. 35, the trial hitting device 1120 includes a trial hitting base 1122 as a trial hitting member. The mounting unit 640 is attached to the test platform 1122 and can be attached to the attachment portion 610 in the same manner as the nozzle stocker 600 and the like.

  The test strike table 1122 includes a one-side test strike surface 1124. The test hitting surface 1124 is horizontal when the test hitting device 1120 is attached to the attachment portion 610, and is coated with polytetrafluoroethylene. Polytetrafluoroethylene is a synthetic resin known under the trade name of Teflon, and is a kind of fluororesin that is stable to almost all organic solvents. It is chemically stable with respect to the product and has excellent durability. Further, it has a low coefficient of friction and has a property that it is difficult for substances to adhere to it, and it is easy to remove the discarded and trial-bonded adhesive.

  Further, the test hitting surface 1124 is provided with a two-dimensional code 1126 as an information recording unit, which constitutes an information recording unit, and records information related to the test hitting device 1120. For example, it is a device that performs discarding and trial hitting, the shape and dimensions of the trial hitting surface 1124, and an individual identification code for individually identifying the trial hitting device 1120.

  In the adhesive application module, discarding and trial driving are performed prior to application of the adhesive to the series of wiring boards 30. The adhesive application head 1100 is moved onto the test hitting surface 1124 to apply the adhesive. First, discarding is performed a preset number of times, and then trial hitting is performed a preset number of times. The adhesive applied to the test hitting surface 1124 by the test hit is picked up by the mark imaging device 178, and for example, it is determined whether or not the application amount is appropriate based on the application area. If the application amount is not appropriate, for example, the application amount is made appropriate by adjusting the adhesive discharge time, adjusting the pressure of the compressed air, or the like.

  The number of discarded hits and the number of trial hits on the test hitting surface 1124 are counted in the computer, and when the sum of the number of times exceeds the set number and the test hitting surface 1124 is full, the operator is informed. The adhesive applied to the test striking surface 1124 is wiped off, and throwing away and test striking are performed again. Or you may make it wipe off whenever the trial hitting device 1120 is removed from the adhesive application module. The trial hitting surface is also a discarded hitting surface.

In addition, when the adhesive application head 1100 is attached instead of the nozzle holding head 40, an application control device is provided instead of the mounting control device 1200 to control the adhesive applicator and the like.

  The plurality of mounting modules 12 operate in association with each operation. In addition, the system according to this basic aspect includes a system controller 1240 (not shown in FIGS. 1 and 2) that controls the entire system separately from the system base 10 and the mounting modules 12 and 13. . Therefore, the other mounting modules 12 and 13 and the system control device 1240 are connected to the input / output interface 1218 via a communication device such as the communication cable 1242. Note that the system control device 1240 is also used as a system control device for another on-board work system when this system is connected to another on-board work system to form a larger system. Further, the mounting module 12 is modular and may be placed in another system. In this case, the mounting control device 1200 can be connected to a control device included in another substrate work apparatus in the other system and a system control device of the other system.

  The ROM 1214 stores a basic operation program of the mounting module 12 and the like, and the RAM 1216 performs operations related to operation control according to the work mode, cooperative operation with other substrate work apparatuses, cooperative operation control, and the like. Various data and the like are stored, such as a program, an application program such as a mounting position correction program corresponding to a shift in the holding position of the wiring board, a shift in the suction holding position of the circuit component 25, a component mounting program, and the like. The component mounting program includes, for example, mounting order data, mounting position data, data of the circuit component 25 mounted at the mounting position, and components related to the mounted circuit component 25 according to the wiring board on which the component mounting operation is performed. Specific data, component supply device related data such as which circuit component 25 is supplied from which tape feeder 26, and the like are included. These data and the like are also stored in the host computer 1250 which is a computer of the system control apparatus 1240. Although not shown in FIG. 36, the lock release control computer 1010 is connected to the host computer 1250.

  In the mounting system configured as described above, various preparation operations are performed before the first mounting operation is started. A typical example is mounting (mounting) of the nozzle holding head 40, the component supply device 24, the nozzle stocker 600, and the like in each of the mounting modules 12 and 13. The type of the nozzle holding head 40 used in the mounting modules 12 and 13 is determined by the type and number of circuit components 25 mounted on the wiring board 30 in each mounting module 12 and 13. The configuration, the type and number of suction nozzles held in each of the mounting modules 12 and 13, and the type of nozzle stocker are also determined. These are determined by the host computer 1250 based on the component mounting program, and supplied to the mounting control computers 1210 of the mounting modules 12 and 13 together with the component mounting program. Here, as the nozzle holding head 40, for example, the nozzle holding head 40 that holds and mounts at most 12 nozzle holding heads 40a and 40b or suction nozzles 158 is used. The nozzle holding head 40 set for each of the mounting modules 12 and 13 is attached to the second X slide 134. In addition, a component supply device 24 that holds the set circuit component 25 is attached to the component supply unit 22. The component supply device 24 may be a feeder type or a tray type.

The attachment of the nozzle stocker 600 and the like to the mounting modules 12 and 13 and the storage of the suction nozzle 158 and the like in the nozzle stocker 600 and the like will be described in detail.
In the stage before the start of the first mounting operation, an empty nozzle stocker 600 or the like in which no suction nozzle 158 or the like is stored, and the set type nozzle stocker 600 or the like is attached to the mounting modules 12 and 13. The suction nozzles 158 and the like stored in the nozzle transport plate 900 are stored in the nozzle stocker 600 and the like by the nozzle holding head 40.

  First, attachment of the nozzle stocker 600 and the like to the mounting modules 12 and 13 will be described. This attachment is performed by an operator. The type of nozzle stocker 600 attached to each of the plurality of mounting modules 12 and 13 is displayed on the display screen 1236. As the types of the nozzle stocker 600 or the like, all of a plurality of elements for identifying the types may be displayed, or may be displayed by a stocker type identification code representing the type including them.

Since the attachment of the plurality of types of nozzle stockers 600 and the like to the attachment portion 610 is performed in the same manner, a case where the nozzle stocker 600 is attached to the mounting module 12 will be described as a representative example.
The operator holds the empty nozzle stocker 600 and attaches it to the attachment portion 610 of the mounting module 12. At this time, in the mounting portion 610, the stocker holding device 760 is positioned at the first position. As shown by a two-dot chain line in FIG. 23, the operator tilts the nozzle stocker 600, and the front portion, that is, the positioning member. The pair of positioning members 644 provided on the positioning block 772 on the stocker holding base 764 with the portion on the side where the pins 644 are provided positioned at the rear, that is, below the side on which the engaging member 646 is provided. The positioning projection 649 is fitted into the positioning recess 778 while being fitted between the guide surfaces 776 and 777, and the rear part of the nozzle stocker 600 is lowered to approach the stocker holding base 764. As a result, the engaging member 646 engages with an engaging lever 790 provided on the stocker holding base 764.

  First, the guide surface 654 is engaged with the roller 792 of the engaging lever 790, and the roller 792 is rotated in a direction away from the engaging member 646 against the biasing force of the spring 794 by the action of the inclined surface. The nozzle stocker 600 is allowed to approach the stocker holding base 764. Then, the nozzle stocker 600 is further advanced to approach the stocker holding base 764, and as shown in FIG. 23, the positioning projection 782 of the positioning pin 774 is fitted into the positioning hole 784 provided in the nozzle storage base 620. The nozzle storage base 620 is seated on the support surface 822 of the support member 820 and the shoulder surface of the positioning pin 774, and is supported from below.

  In this state, the roller 792 of the engagement lever 790 is engaged with the engagement surface 656 of the engagement member 646, and the nozzle stocker 600 is fixed in a state of being positioned on the stocker holding base 764. The roller 792 of the engagement lever 790 is pressed against the engagement surface 656 by the urging of the spring 794, the inclined surface 650 of the positioning protrusion 649 is pressed against the inclined surface 780 of the positioning recess 778, and the nozzle stocker 600 is moved in the front-rear direction. In addition to being positioned, the front portion of the nozzle stocker 600 is pressed against the support member 820 provided on the front side of the stocker holding base 764 due to the effect of the inclined surface, thereby preventing lifting. In addition, due to the effect of the inclined surface of the engagement surface 656, the rear portion of the nozzle stocker 600 is pushed downward and is pressed against the support member 820 and the like, and lifting is prevented even at the rear portion. Further, the nozzle stocker 600 is positioned in the width direction or the left-right direction by fitting the positioning protrusion 649 to the positioning recess 778 and fitting the positioning hole 784 to the positioning protrusion 782.

  Attachment of the nozzle stocker 600 to the attachment portion 610 is detected by a stocker presence / absence detection device 824. When the nozzle stocker 600 is seated on the support member 820 or the like, the detector 826 of the stocker presence / absence detecting device 824 is pushed, and it is detected that the nozzle stocker 600 is attached to the attachment portion 610.

  Thus, when the nozzle stocker 600 is attached to the stocker holding stand 764, the shutter 622 is positioned at the nozzle removal preventing position by the bias of the spring 668. In the stocker holding device 760, the piston rod 804 of the shutter moving device 770 is located at the extended end position, the engaging portion 806 is located at the forward end position, and is located at the fitting standby position, and the nozzle stocker 600 is When attached to the stocker holding base 764, the engaging portion 808 is fitted into the opening 674 of the shutter 622. At this time, the inclined surface 810 provided in the engaging portion 808 guides the fitting of the opening 674 to the engaging portion 808 and is smoothly fitted.

  In a state where the nozzle stocker 600 is held by the stocker holding device 760, the lock device 710 is controlled by the mounting control computer 1210, and the shutter action can be released and the shutter moving device 770 can be moved by the shutter moving device 770. The locking action of the locking device 710 is only mechanically released by supplying current to the solenoid. The operator can lock the locking device 710 regardless of whether the nozzle stocker 600 is attached to or removed from the mounting module 12. Cannot be released. In this embodiment, the lock device 710 allows the suction nozzle 158 to be taken out by the nozzle holding head 40, but is prevented from being taken out by a person, and the suction nozzle 158 is taken out when the nozzle stocker 600 is attached to the mounting machine body. Is allowed, and removal is prevented in a state where it is removed from the mounting machine main body. In the state where the nozzle stocker 600 is attached to the stocker holding stand 764, the engaging member 808 of the shutter moving device 770 is fitted into the opening 674 of the shutter 622, and the air cylinder 800 of the shutter moving device 770 has air. Even if the locking action by the locking device 710 is released, the operator cannot move the shutter 622, and the shutter moving device 770 can be operated by a person with the nozzle stocker 600 attached to the mounting machine body. It can also be considered that a device for preventing the suction nozzle from being taken out is configured.

  After the nozzle stocker 600 and the like are attached to all the mounting modules 12 and 13, the suction nozzle 158 and the like are transported by the nozzle transport plate 900, and transferred to and stored in the nozzle stocker 600 and the like by the nozzle holding head 40.

  The nozzle conveying plate 900 accommodates the suction nozzle 158 and the like by an operator outside the apparatus. Therefore, the type of the nozzle storage member 912, the type of the suction nozzle 158 for each nozzle storage member 912, the number of storage, and the like are set and displayed on the display screen. This display screen is a display screen (not shown) that is provided in a work place where the suction nozzle 158 and the like are stored in the nozzle transport plate 900 and is controlled by the host computer 1250.

  As described above, there are a plurality of types of nozzle storage members 912, and the nozzle storage member 912 corresponding to the type of nozzle holding head 40 attached to the mounting module, the type of suction nozzle to be held, and the number of suction storage nozzles 158, etc. Used for transporting. These are determined for each mounting module by the host computer 1250 and displayed on the display screen together with the mounting module of the nozzle transport destination. Based on this display, the operator stores the suction nozzle 158 and the like in the nozzle storage member 912. These suction nozzles 158 and the like may be stored in any position of the nozzle storage member 912. The suction nozzle 158 and the like are housed in the nozzle housing member 912 at a constant phase by fitting the positioning pins 632 to the engaging recesses 408 and the like.

  In addition, each nozzle stocker including the nozzle stockers 600 and 602 includes only two sets (one type of suction nozzles) of the kind of suction nozzles 158 necessary for mounting the circuit component 25 on one wiring board 30. When the nozzles 158 and the like are held by the nozzle holding head 40 at the same time, the suction nozzles 158 and the like that are twice the number held are held. This is because the suction nozzle 158 or the like being used is used for replacement when it becomes unusable due to wear or damage. However, it is not indispensable that the number of the necessary suction nozzles 158 etc. is held twice as many as the number of necessary suction nozzles 158 etc., and the number of spare suction nozzles 158 etc. may be one for each type. The spare suction nozzle 158 itself can be omitted. The type and number of these auxiliary suction nozzles 158 and the like are also displayed on the display screen and stored in the nozzle storage member 912.

A case where the nozzle holding head 40a and the nozzle stocker 600 are attached to one of the plurality of mounting modules 12 and the suction nozzle 158 is supplied to the mounting module 12 by the nozzle transport plate 900 holding the suction nozzle 158 will be described.
A nozzle transport plate 900 having a nozzle housing member 912 in which the suction nozzle 158 is housed is placed on one of the front conveyor unit 260 and the rear conveyor unit 262 (the front conveyor unit 260 in this embodiment) of the wiring board transport device 34. Thereafter, when the operator operates a manual operation member that instructs the start of nozzle supply, the nozzle transport plate 900 is transported, and the nozzle transport plate 900 supplies the suction nozzle 158 by the wiring board holding device 32 in the mounting module 12. Positioned and held. If the nozzle transport plate 900 supplies the suction nozzles 158 to the plurality of mounting modules 12, among them, the nozzle transport plate 900 is positioned and held by the wiring board holding device 32 in the most upstream module 12 in the transport direction. The nozzle storage member 912 conveys the suction nozzle depending on the type, and the partner nozzle holding head 40 to be provided is determined and the mounting module is determined. If possible, one nozzle storage member 912 holds the same type of nozzle. If there is a plurality of mounting modules in which the head 40 is used or a mounting module in which the suction nozzle 158 is used even if the type of the nozzle holding head 40 is different, the suction nozzles may be conveyed to the plurality of mounting modules. . Subsequently, the mark imaging device 178 is moved above the nozzle conveyance plate 900, the reference mark 930 provided on the nozzle conveyance plate 900 is imaged, and the holding position of the held nozzle conveyance plate 900 is determined from the imaging data. A deviation is detected.

  Then, the two-dimensional code 406 of each suction nozzle 158 held on the nozzle transport plate 900 is imaged, and image data is subjected to image processing in the image processing unit 1224 to read nozzle information. In the nozzle transport plate 900, the plurality of suction nozzles 158 are all held at a constant phase, and the mark imaging device 178 is moved to a set position facing the portion where the two-dimensional code 406 is disposed, The dimension code 406 is imaged. The position of the nozzle storage hole of the nozzle holding member 912 is set with reference to the reference mark 930, and the position of the two-dimensional code 406 stored at a constant phase is obtained from the storage position, and the mark imaging device 178 Moved. The positions of the nozzle housing holes and the positions of the reference marks 930 are stored in the host computer 1250 corresponding to the type of the nozzle holding member 912 and supplied to the mounting control computer 1210. The type of each suction nozzle 158 is specified from the information recorded in the two-dimensional code 406, and the storage position of each suction nozzle 158 on the nozzle transport plate 900 is determined based on the amount of movement of the mark imaging device 178 in the XY direction. Identified. Conveying plate nozzle storage data including the types and storage positions of the suction nozzles 158 is stored in the RAM 1216 of the mounting control computer 1210 of the mounting module 12 and is also transmitted to the host computer 1250 for storage. The reading operation of the two-dimensional code 406 is performed for all the nozzle accommodation holes 624 of the nozzle accommodation member 912, and when nozzle information is not obtained, information on no nozzle is stored in association with the arrangement. This data also forms transport plate nozzle storage data.

  In the nozzle storage member 912, for example, a fluorescent layer is provided on the bottom surface of the small-diameter hole portion 952 of the nozzle storage hole 624, and nozzle information can be obtained even when the reference mark imaging device 178 reads the two-dimensional code 406. If not, the nozzle storage hole 624 may be imaged by the mark imaging device 178 to detect the presence or absence of the suction nozzle 158. Thereby, if the suction nozzle 158 is detected, for example, the imaging position of the two-dimensional code 406 by the mark imaging device 178 is changed, information is read, and if the two-dimensional code 406 is imaged, The storage phase of the suction nozzle 158 may be stored based on the phase of the two-dimensional code 406 at that time, and may be stored in the nozzle stocker 600.

  When the nozzle storage data in the nozzle transport plate 900 is obtained in this way, the nozzle holding head 40a takes out the suction nozzle 158 from the nozzle transport plate 900, transports it to the nozzle stocker 600, and stores it in the nozzle storage hole 624. Prior to this storage, the two-dimensional code 696 provided in the nozzle stocker 600 is imaged by the mark imaging device 178, and stocker information recorded thereon is read. The position of the two-dimensional code 696 when the nozzle stocker 600 is attached to the attachment portion 610 is constant regardless of the type of the nozzle stocker 600 and is set in advance, and the mark imaging device 178 moves to the two-dimensional code 696. Moved to take an image. If the nozzle stocker 600 is attached to the stocker holding stand 764 and the attachment is detected by the stocker presence / absence detection device 824, the two-dimensional code 696 is imaged. When imaging the two-dimensional code 696, the stocker holding base 764 is raised by the holding device lifting device 762, the nozzle stocker 600 is moved to the second position, and the two-dimensional code 696 is positioned at a height suitable for imaging. . The second position is an imaging position. Based on the acquisition of stocker information, an empty stocker confirmation routine shown in FIG.

  In step 1 of the empty stocker confirmation routine (hereinafter abbreviated as S1; the same applies to other steps), it is determined whether or not the type of nozzle stocker 600 attached to the attachment portion 610 is correct. If the nozzle stocker type obtained by reading the two-dimensional code 696 matches the set nozzle stocker type, the determination result in S1 is YES, S2 is executed, nozzle storage permission is set, and the routine is executed. Execution ends.

  If the actually installed nozzle stocker type does not match the set nozzle stocker type, the determination result in S1 is NO and S3 is executed. As described above, the two-dimensional code 696 or the like has a horizontal XY coordinate plane in each of the mounting modules 12 and 13 when the nozzle stocker is attached to the attachment portion 610 even if the type of the nozzle stocker is different. Even if a different type of nozzle stocker is attached, the two-dimensional code 696 and the like are imaged, stocker information is obtained, and the determination of S1 is performed. In S3, it is determined whether or not the attached nozzle stocker can be used even if the type of nozzle stocker is different. This determination is performed, for example, based on whether or not all the suction nozzles 158 set for the mounting module 12 to which the nozzle stocker is attached can be accommodated in the nozzle stocker actually attached. If there is, the determination result in S3 is YES and S2 is executed.

  On the other hand, if it cannot be stored, the determination result in S3 is NO, S4 is executed, and the display screen 1236 displays and notifies that the type of nozzle stocker attached to the attachment portion 610 is incorrect. The The operator replaces the nozzle stocker according to the display. The portion of the mounting control device 1200 that executes S1 constitutes an empty nozzle stocker type confirmation unit, and the stocker type information is used to confirm the type of nozzle stocker.

  Here, if the nozzle stocker 600 designated by the mounting portion 610 is attached and nozzle storage is permitted, the suction nozzle 158 is automatically stored in the nozzle stocker 600 by the nozzle holding head 40a. At this time, the stocker reference mark 698 provided in the nozzle stocker 600 is imaged by the mark imaging device 178 prior to the storage, the mounting position error of the nozzle stocker 600 is acquired, and each of the plurality of nozzle storage holes 624 of the nozzle stocker 600 is acquired. A mounting position error is obtained for. In this embodiment, this attachment position error includes each position error in the X-axis and Y-axis directions at the center of the nozzle housing hole 624. The position of the stocker reference mark 698 is obtained from the stocker information. Even when the stocker reference mark 698 is imaged, the nozzle stocker 600 is positioned at the second position, and imaging is performed well. .

  The nozzle holding head 40a is moved to the nozzle transport plate 900 to hold the suction nozzle 158, and transports it to the nozzle stocker 600 for storage. The nozzle transport plate 900 is stopped at a stop position controlled based on the detection signal of the photoelectric sensor 320, and the support plate 300 is raised to the rising end position by the support plate lifting device 308, whereby a pair of supported portions is supported. 917 is pressed against the locking portion 310 and supported from below by the backup pin 302, and the nozzle storage member 912 and the stored suction nozzle 158 are positioned at a predetermined transfer position in the vertical direction.

  As described above, the thickness of the nozzle storage member 912 is set according to the type of the nozzle holding head 40, and the suction is performed in the state where the nozzle transport plate 900 is raised to the rising end position by the support plate lifting device 308. Nozzle conveyance for conveying the suction nozzle 158 to the mounting module 12 to which the nozzle holding head 40a is attached, in which the nozzle 158 and the like are sized to be positioned at a height suitable for delivery to and from the nozzle holding head 40. In the state where the plate 900 is raised to the rising end position, the suction nozzle 158 is positioned at the same height as the suction nozzle 158 housed in the nozzle stocker 600 raised to the third position. . Therefore, the transfer of the suction nozzle 158 between the nozzle holding head 40a and the nozzle transport plate 900 is performed in the same manner as the transfer of the suction nozzle 158 to the nozzle stocker 600.

  The nozzle holder 160 of the nozzle holding head 40a is moved and held on the suction nozzle 158 housed in the nozzle transport plate 900. At this time, the plurality of nozzle holders 160 of the nozzle holding head 40a are all empty. In the present embodiment, all of the plurality of nozzle holders 160 of the nozzle holding head 40a are used for storing the suction nozzle 158 in the nozzle stocker 600. Some nozzle holders 160 may be used for storage. The order in which the suction nozzles 158 are held by the plurality of nozzle holders 160 is set in advance, and the order in which the suction nozzles 158 are taken out from the nozzle transport plate 900 is also set in advance based on the transport plate nozzle storage data. Is moved to the nozzle storage hole 624 to sequentially hold the suction nozzles 158, and if all the nozzle holders 160 hold the suction nozzles 158, they are moved to the nozzle stocker 600 for storage. For example, the suction nozzle 158 is taken out in order from the end of the nozzle transport plate 900, or the suction pipe 362 is taken out in descending order.

  Since the holding operation of the suction nozzle 158 by the plurality of nozzle holders 160 is performed in the same manner, one will be representatively described based on FIG. FIG. 38 is a view for explaining the operation when the suction nozzle 158 held by the nozzle holder 160 is housed in the nozzle stocker 600. In the nozzle transport plate 900, the suction nozzle 158 is held in the same manner as in the nozzle stocker 600. The transfer of the suction nozzle 158 between the nozzle holder 160 and the nozzle transport plate 900 is performed in the same manner as the transfer between the nozzle stocker 600 and the holding operation of the suction nozzle 158 by the nozzle holder 160 is performed by the suction nozzle 158. 38, the holding of the suction nozzle 158 by the nozzle holder 160 will be described with reference to FIG. 38, but there are portions that do not match the illustration of FIG.

  The nozzle holder 160 is moved onto the suction nozzle 158 by the movement of the nozzle holding head 40a. At this time, the moving position of the nozzle holding head 40a is corrected so that the position error previously acquired based on the imaging of the reference mark 930 of the nozzle transport plate 900 is canceled, and the nozzle holder 160 is positioned on the suction nozzle 158. It can be moved with little deviation.

  The nozzle holder 160 that holds the suction nozzle 158 is positioned at the holder lifting / lowering station, and is lifted / lowered by the holder lifting / lowering device 172. A lift stroke L1 for holding and releasing the suction nozzle 158 by the nozzle holder 160 of the nozzle holding head 40a is set in advance. The nozzle holder 160 is rotated to a position where the phase of the pin 384 coincides with the engagement recess 398 of the suction nozzle 158 housed in the nozzle transport plate 900. As the nozzle holder 160 is lowered by the holder lifting and lowering device 172, the tapered hole 372 of the nozzle chuck 350 is fitted into the tapered portion 370 of the suction nozzle 158 and the holding member as shown in FIG. The lowering of 386 is stopped by the head 692 of the anti-lifting member 690.

  When the nozzle holder 160 is further lowered from this state, as shown in FIG. 38B, the chuck body 352 is lowered with respect to the holding member 386, and the spring member 374 is fitted into the groove 378, so that the suction tube The holding body 360 is held. The nozzle holder 160 is lowered by a small distance after that, and the suction nozzle 158 is securely held. At this time, the lowering of the nozzle holder 160 is allowed by the compression of the spring 358. Thereafter, the nozzle holder 160 is raised. At that time, the shutter 940 (corresponding to the shutter 622 shown in FIG. 38) is moved to the nozzle take-out allowable position, and both the suction nozzles 158 are raised, as shown in FIG. As shown, the positioning pin 632 of the nozzle receiving hole 624 is pulled out of the engaging recess 408 of the suction nozzle 158, and the pin 384 of the nozzle chuck 350 is fitted into the engaging recess 398, so that the suction nozzle 158 with respect to the nozzle holder 160 is shown. Relative rotation is blocked and the phase is determined. Then, the nozzle holder 160 is further raised, and the suction nozzle 158 is pulled out from the nozzle storage hole 624 of the nozzle transport plate 900.

The storage of the suction nozzle 158 held by the nozzle holder 160 in the nozzle stocker 600 will be described.
When the suction nozzle 158 is stored by the nozzle holding head 40a, the nozzle stocker 600 is positioned at the third position. The storage order of the suction nozzles 158 in the nozzle stocker 600 is set in advance, and the plurality of nozzle holders 160 holding the suction nozzles 158 are moved to the set nozzle storage holes 624 to store the suction nozzles 158. The nozzle holder 160 is moved so that the position error of the nozzle storage hole 624 acquired based on the image of the stocker reference mark 698 is canceled, and the suction nozzle 158 is securely stored in the nozzle storage hole 624. The correction of the movement position of the nozzle holder 160 based on the imaging of the stocker reference mark 698 is performed in the same manner when the nozzle holder 160 receives the suction nozzle 158 from the nozzle stocker 600. The same applies to the transfer of the suction nozzle 182 between the nozzle holder 180 and the nozzle stocker 602, and the transfer is reliably performed.

  The nozzle holder 160 moved onto the nozzle housing hole 624 is lowered in a state where it is rotated to a position where the phases of the engaging recess 408 of the suction nozzle 158 and the positioning pin 632 of the nozzle housing hole 624 coincide with each other. . At this time, the shutter 622 is moved to the nozzle take-out allowable position by the shutter moving device 770. As the nozzle holder 160 is lowered, first, as shown in FIG. 38A, the holding member 386 of the nozzle chuck 350 is brought into contact with the head portion 692 of the lifting prevention member 690 to stop the lowering. When the nozzle holder 160 is further lowered from this state, the background forming portion 396 of the suction nozzle 158 is fitted into the large-diameter hole portion 626 of the nozzle storage hole 624 and engaged as shown in FIG. The positioning pin 632 is fitted into the recess 408 and the pin 384 is pulled out of the engagement recess 398.

  After the suction nozzle 158 is fitted into the nozzle housing hole 624, the shutter 622 is moved to the nozzle removal prevention position, and then the nozzle holder 160 is raised. In the suction nozzle 158, the background forming portion 396 is pressed by the shutter 622 to prevent the suction from the nozzle housing hole 624. As shown in FIG. The suction nozzle 158 is pulled out of the nozzle holder 160 and stored in the nozzle stocker 600 by overcoming the holding force.

  Although the nozzle stocker 600 should be empty, it may be detected whether or not the nozzle storage hole 624 is empty when the suction nozzle 158 is stored. This detection will be described later. If the nozzle storage hole 624 that should be empty is not empty, for example, the nozzle storage operation is interrupted there, and a notification to that effect is given.

  The two-dimensional code 406 of the suction nozzle 158 stored in the nozzle stocker 600 is read in a state where the suction nozzle 158 is stored in the nozzle transport plate 900, and the nozzle holding head 40a is moved from the moving distance in the XY direction to the nozzle. The storage position and arrangement of the suction nozzle 158 in the stocker 600 are obtained, and stocker nozzle storage information in which the nozzle information obtained for the suction nozzle 158 stored in the nozzle stocker 600 is associated with the storage position is obtained. Stocker / nozzle information obtained in association with the identification information is stored in the stocker / nozzle information memory of the RAM 1216 of the mounting control computer 1210. The stocker / nozzle information is sent to the host computer 1250 and stored in a stocker / nozzle information memory provided there.

  In this embodiment, the lock device 710 is locked except when the suction nozzle 158 is exchanged between the nozzle holder 160 and the nozzle stocker 600. When the delivery of the suction nozzle 158 is completed, the lock device 710 Is locked so that the shutter 622 is not opened. Accordingly, even when the nozzle stocker 600 is removed from the mounting module 12, the lock device 710 is locked and the shutter 622 cannot be moved.

  If all the suction nozzles 158 set for the mounting module 12 are accommodated in the nozzle stocker 600 and the nozzle transport plate 900 supplies the suction nozzles 158 to another mounting module 12, the nozzle transport plate 900 will be mounted next. The suction nozzle 158 is similarly housed in the nozzle stocker 600 after being moved to the module 12.

The conveyance and supply of the suction nozzle 182 by the nozzle conveyance plate 900 will be described.
The suction nozzle 182 is stored in the nozzle storage member 912 by the operator according to the display of the type of the nozzle storage member 912 on the display screen, the type and number of the suction nozzles 182 to be transported, and the like. Is called. The suction nozzle 182 is housed in the nozzle housing member 912 at a constant phase with the engaging recess 504 fitted to the positioning pin 732. The nozzle transport plate 900 holding the suction nozzle 182 is moved to the mounting module to which the nozzle holding head 40b is attached, for example, the mounting module 13 to supply the suction nozzle 182, and the suction nozzle 182 is supplied to the mounting module 13. It is stored in the attached nozzle stocker 602.

  The nozzle transport plate 900 in which the suction nozzle 182 is accommodated is moved to the mounting module 13 that supplies the suction nozzle 182, stopped at a predetermined position, and held by the wiring board holding device 32 and lifted to the rising end position. Be made. The thickness of the nozzle storage member 912 of the nozzle transport plate 900 that holds the suction nozzle 182 is the same as the nozzle in which the suction nozzle 182 is moved to the third position when the nozzle transport plate 900 is raised to the rising end position. The thickness of the nozzle holder 180 of the nozzle holding head 40b is the same as the delivery of the suction nozzle 182 to and from the nozzle stocker 602. The suction nozzle 182 is transferred to and from the nozzle transport plate 900. Further, the reference mark 930 provided on the nozzle transport plate 900 is imaged to acquire a holding position error, and the two-dimensional code 506 of the suction nozzle 182 is imaged to acquire transport plate nozzle storage information.

  The nozzle holder 180 is moved onto the suction nozzle 182 by the movement of the nozzle holding head 40b, and the suction nozzle 182 is held. At this time, the movement position of the nozzle holder 180 is corrected so that the holding position error acquired by imaging the reference mark 930 is canceled for each of the nozzle storage holes. The nozzle holder 180 is lowered in a state where the pair of spring members 512 are positioned in a phase that coincides with the openings 524 of the pair of grooves 520 of the suction nozzle 182. At this time, the shutter 940 of the nozzle transport plate 900 is positioned at the nozzle take-out allowable position, and the suction surface 472 of the suction member 458 of the nozzle holder 180 abuts on the suction target surface 500 of the background forming portion 494 of the suction nozzle 182. In addition, the engaging portion 516 of the spring member 512 is fitted into the opening 524.

  From this state, the nozzle holder 180 is rotated by a holder rotating device 432 in a predetermined direction by a predetermined angle. The suction nozzle 182 is positioned in the nozzle storage hole 724 by fitting the positioning pin 732 into the engagement recess 504 and is prevented from rotating relative to the nozzle stocker 602, so that the nozzle holder 180 is positioned relative to the suction nozzle 182. The engagement portion 516 of the spring member 512 is moved in the direction away from the opening 524 in the groove 520, and the engagement portion 516 engages with the side surface 526 of the groove 520 to hold the suction nozzle 182. State. Then, a negative pressure is supplied to the negative pressure chamber forming chamber 470, and the nozzle holder 180 sucks and holds the suction nozzle 182 by the negative pressure and mechanically holds it by the spring member 512. Therefore, for example, even if the supply of negative pressure is interrupted, the suction nozzle 182 is prevented from falling from the nozzle holder 180. After holding the suction nozzle 182, the nozzle holder 180 is raised and the suction nozzle 182 is taken out from the nozzle transport plate 900.

  The suction nozzle 182 held by the nozzle holding head 40 b is stored in the nozzle stocker 602. After the nozzle stocker 602 is mounted on the mounting portion 610, the two-dimensional code 736 provided in the nozzle stocker 602 is imaged before the suction nozzle 182 is stored, and the type of the nozzle stocker 602 is confirmed. This is the same as the case of storage in the nozzle stocker 600 of 158. Prior to storage, the stocker reference mark 738 is imaged, and the mounting position error of the nozzle stocker 602 is acquired. During the imaging of the two-dimensional code 736 and the stocker reference mark 738, the nozzle stocker 602 is positioned at the second position, and imaging is performed satisfactorily.

  If the type of the nozzle stocker 602 is confirmed and the nozzle storage permission is created, the suction nozzle 182 is stored in the nozzle stocker 602. At this time, as shown in FIG. 42, the nozzle stocker 602 is raised to the third position, the locking action by the locking device 710 is released, and the shutter 722 is moved to the nozzle removal allowance position. In the nozzle stocker 602, when the suction nozzle 182 is transferred, the shutter 722 remains positioned at the nozzle take-out allowable position. The nozzle holder 180 is lowered in a state where the phase of the engaging recess 504 provided in the background forming portion 494 of the suction nozzle 182 and the positioning pin 732 fitted in the nozzle storage hole 724 coincide with each other, and the suction nozzle 182 The background forming portion 494 is fitted into the background forming portion receiving hole 726 of the nozzle receiving hole 724, and the positioning pin 732 is inserted into the engaging recess 504 to be positioned, thereby preventing relative rotation.

  Then, the supply of the negative pressure to the negative pressure chamber forming chamber 470 is cut off, the holding of the suction nozzle 182 by the nozzle holder 180 is released, and the nozzle holder 180 is moved at a predetermined angle in the direction opposite to that when the suction nozzle 182 is held. Rotated and rotated relative to the suction nozzle 182. As a result, when the engaging portion 516 of the spring member 512 reaches the opening 524 of the groove 520 and the nozzle holder 180 is raised, the spring member 512 is pulled out of the background forming member 494, and the suction nozzle 182 is removed from the nozzle holder 180. It is released and stored in the nozzle stocker 602. After all the suction nozzles 182 are stored in the nozzle stocker 602, the shutter 722 is closed. In addition, stocker / nozzle information is obtained for the nozzle stocker 602 and stored in each stocker / nozzle information memory of the mounting control computer 1210 and the host computer 1250.

  In each of the mounting modules 12 and 13, after the suction nozzle 158 and the like are accommodated in the nozzle stocker 600 and the like, the nozzle holding head 40 is moved to above the nozzle stocker 600 and the like, which is necessary for mounting the wiring board 30 this time. The suction nozzle 158 and the like are sequentially held by the nozzle holder 160 and the like. This holding is performed based on stocker / nozzle information. At this time, the nozzle stocker 600 and the like are positioned at a height corresponding to the type of the nozzle holding head 40, and the suction nozzle 158 and the like are exchanged. The holding of the suction nozzle 158 and the like is performed in the same manner as the holding of the suction nozzle 158 and the like housed in the nozzle transport plate 900, and thus description thereof is omitted. In the nozzle stocker 600 and the like, the lock by the locking device 710 is released, but in principle, the shutter 622 and the like are closed except when the suction nozzle 158 and the like are exchanged with the nozzle holder 160 and the like, and the nozzle removal prevention position Is located. Note that when the suction nozzle 158 or the like is stored in the nozzle stocker 600 or the like, the nozzle holding head 40 may hold the suction nozzle 158 or the like necessary for mounting.

  Next, component mounting work on the wiring board 30 will be described by taking the mounting module 12 to which the nozzle holding head 40a is mounted as an example. The case where the component mounting work by one mounting module 12 is a work for the wiring board 30 having a size that fits within the mounting area of the mounting module 12 will be briefly described as an example. The wiring board 30 transported from the upstream side is stopped by the wiring board transporting device 34 at the set work position in the mounting area. The stopped wiring board 30 is fixed and held by the wiring board holding device 34 when the support plate 300 is raised at that position. Next, the mark moving device 178 is moved above the reference mark attached to the wiring board 30 by the head moving device 44 and images the reference mark. A shift in the holding position of the held wiring board 30 is detected from the acquired imaging data.

  Next, the nozzle holding head 40a is moved above the component supply device 24, and the circuit component 25 is sucked and held by the suction nozzle 158 in accordance with the set extraction order. Specifically, the nozzle-equipped holder 161 located in the lifting station is positioned above the component extraction portion of the tape feeder 26 that supplies the circuit component 25 to be held, and the nozzle-equipped holder 161 descends at that position. The negative pressure is supplied to the suction nozzle 158 held at the tip, and the circuit component 25 is sucked and held. Then, the holder holding body 164 is intermittently rotated, and a similar component extraction operation for the next nozzle-equipped holder 161 is performed. In this way, the component extraction operation (in many cases, eight times) is sequentially performed on the nozzle-mounted holder 161 included in the nozzle holding head 40a.

  Next, the nozzle holding head 40 a holding the circuit component 25 is moved above the component imaging device 50. At that position, the component imaging device 50 captures and captures the held circuit component 25 within one field of view. A shift in the holding position of each circuit component 25 is detected from the obtained imaging data. The nozzle holding head 40 is moved above the wiring board 30. During the movement, the nozzle-equipped holder 161 is rotated by the holder rotation device 176 and set to the circuit component 25 held by the holder. Based on the mounting orientation, the detected wiring board holding position deviation amount, and the holding position deviation amount of the circuit component 25, the rotation is made to an appropriate rotation position. The holder holder 164 or the nozzle holder 161 is repeatedly intermittently rotated until the nozzle-mounted holder 161 that holds the circuit component 25 to be mounted first is positioned at the lifting station, and the circuit component 25 is mounted during the intermittent rotation. The nozzle-equipped holder 161 is rotated.

  Subsequently, the nozzle holding head 40a is moved to above the wiring board 30, and the held circuit component 25 is mounted on the surface of the wiring board 30 in accordance with the set mounting order. Specifically, first, the nozzle-equipped holder 161 located at the holder lifting / lowering station is positioned above the appropriate mounting position. At this time, the movement position of the nozzle holding head 40 is optimized based on the detected wiring board holding position deviation amount and the holding position deviation amount of the circuit component 25. At that position, the nozzle-equipped holder 161 is lowered by a predetermined distance, positive pressure is supplied to the suction nozzle 158, and the held circuit component 25 is mounted on the surface of the wiring board 30. Subsequently, the nozzle-equipped holder 161 is intermittently rotated, and the same component mounting operation relating to the next nozzle-equipped holder 161 is performed. In this manner, the component mounting operation is sequentially performed on the nozzle-equipped holder 161 that holds the circuit component 25.

  The nozzle holding head 40a is reciprocated between the component supply device 24 and the wiring board 30 until the mounting of all the planned circuit components 25 is completed, and the component extraction operation and the component mounting operation are repeatedly performed. After the mounting of all the circuit components 25 is completed, the support plate 300 of the wiring board transport device 34 is lowered, and the fixed holding of the wiring board 30 is released. The wiring board 30 is transferred to the downstream side by the wiring board conveying device 34. In this way, the component mounting operation scheduled for the mounting module 12 for the wiring board 30 is completed. In the present system, the component mounting operation can be performed also on the wiring board 30 having a size straddling both adjacent two mounting modules 12.

  When the suction nozzle 158 or the like held by the nozzle holding head 40a is replaced during the mounting, the nozzle holding head 40a is moved to the nozzle stocker 600, and the suction nozzle 158 currently held by the nozzle holder 160 is moved to the nozzle stocker 600. The other suction nozzle 158 is held. At this time, in principle, the suction nozzle 158 is returned to the nozzle storage hole 624 in which it is stored.

  Prior to returning the suction nozzle 158, it is confirmed whether or not the nozzle housing hole 624 is empty. A fluorescent layer 634 is provided on the bottom surface of the small diameter hole portion 628 of the nozzle housing hole 624, the mark imaging device 178 is moved onto the nozzle housing hole 624, and the illumination device 192 emits blue light toward the fluorescent layer 634. Is confirmed based on the amount of reflected light. The blue light usually contains a relatively large amount of ultraviolet light, and when the fluorescent layer 634 is irradiated with blue light, visible light is emitted from the fluorescent layer 634. If the suction nozzle 158 is stored in the nozzle storage hole 624, blue light hits the background forming portion 396, but no visible light is emitted. Accordingly, the CCD camera 190 images the portion including the nozzle storage hole 624 of the nozzle stocker 600. The brightness detected by the imaging differs depending on whether the suction nozzle 158 is stored, and the brightness detection value is the set value. If it is smaller, it is detected that the suction nozzle 158 is stored, and if it is larger than the set value, it is detected that the suction nozzle 158 is not stored. If the suction nozzle 158 is not stored in the nozzle storage hole 624 and is empty, the nozzle holder 160 is moved onto the nozzle storage hole 624 and the suction nozzle 158 is stored. Note that the detection of the presence or absence of the suction nozzle 158 by imaging is performed in a state where the nozzle stocker 600 is located at the same position as when the suction nozzle 158 is transferred in the height direction, and here in a state where it is located at the third position. Done.

  The presence / absence of the suction nozzle 158 in the nozzle storage hole 624 can also be detected by, for example, imaging the two-dimensional code 406 of the suction nozzle 158 and obtaining the suction nozzle information. However, for example, when the two-dimensional code 406 is provided at the wrong position of the suction nozzle 158, the suction nozzle information is not obtained, and it is assumed that there is no suction nozzle 158. In contrast, if the nozzle storage hole 624 is provided with a fluorescent layer 634 to detect the presence or absence of the suction nozzle 158, the presence or absence of the suction nozzle 158 can be detected easily and reliably by imaging the portion including the nozzle storage hole 624. can do.

  If the nozzle storage hole 624 is not empty for some reason, an empty nozzle storage hole 624 that may store the suction nozzle 158 is searched, and if there is an empty nozzle storage hole 624, there is It is stored in. The empty nozzle storage hole 624 is searched based on, for example, stocker nozzle storage information. If there is no empty nozzle storage hole 624, for example, the mounting operation is interrupted and this is notified by display on the display screen 1236 or the like. If the suction nozzle 158 is stored in another nozzle storage hole 624, the arrangement of the suction nozzle 158 will be different from the initial storage. However, since the storage is mechanically performed by the movement of the nozzle holding head 40, etc., the suction nozzle 158 It is known in which nozzle storage hole 624 is stored, and the stocker nozzle storage information is updated. The stocker / nozzle information stored in association with the individual stocker identification information is also updated. Whether or not the nozzle storage hole 624 is empty is always checked when the suction nozzle 158 is returned to the nozzle stocker 600 and stored.

  After returning the suction nozzle 158 to the nozzle stocker 600, the nozzle holding head 40a is moved onto the next holding suction nozzle 158 to hold it. At this time, the two-dimensional code 406 of the suction nozzle 158 may be imaged, and suction nozzle information may be acquired to check whether or not the type of the suction nozzle 158 is a type to be held. When the type of the suction nozzle 158 to be held is different from the designated type, for example, the fact is notified and the operation of the electronic circuit component mounting machine is stopped, or another nozzle is determined from the stocker nozzle storage information. It is checked whether or not the type of suction nozzle 158 indicated in the storage hole 284 is stored, and if so, the suction nozzle 158 may be held. The same applies when the nozzle holding head 40a holds the suction nozzle 158 at the start of the mounting operation.

  If the type of the wiring board 30 changes, the setup change is performed. When changing the setup, for example, in addition to replacing the feeder 26 in the component supply device 24, if necessary, the nozzle holding head 40, the nozzle stocker 600, etc. are replaced, and the conveyance width of the rails 250, 252, 254, 256 is adjusted. Is called. When the nozzle stocker 600 or the like is replaced, all the suction nozzles 158 and the like that are actually held by the nozzle holding head 40 are returned to the nozzle stocker 600 and the like.

  When the type of the wiring board 30 changes and the type and number of the suction nozzles 158 used for mounting in the mounting modules 12 and 13 change, the suction nozzles 158 and the like are replaced together with the nozzle stocker. As described above, the empty nozzle stocker 600 or the like is attached to the mounting modules 12 and 13, and the suction nozzles 158 or the like are stored therein, whereby the types of the suction nozzles 158 or the like stored for each nozzle stocker 600 or the like, The number and arrangement are obtained, and stocker nozzle storage information is obtained. The stocker nozzle storage information is stored in the stocker / nozzle information memory of the host computer 1250 in association with the stocker individual identification information, and the mounting module 12, based on the type of the wiring board 30 and the type of the nozzle holding head 40, The type and number of suction nozzles required in each of the nozzles 13 are determined, and based on the stocker / nozzle information, it is searched whether there is a nozzle stocker 600 or the like in which the suction nozzles 158 are already stored. If there is, the stocker individual identification information such as the nozzle stocker 600 is displayed on the display screen 1236 together with the data for instructing the mounting module, and the installation is instructed to the operator. Since stocker nozzle storage information is stored in association with individual stocker identification information, nozzle stockers with different types and numbers of stored suction nozzles can be identified even if the types are the same, depending on the storage contents. Thus, the required nozzle stocker can be selected and attached to the mounting module. The determination of the nozzle stocker to be used is an aspect of using the individual stocker identification information and the stocker / nozzle information, and the portion of the host computer 1250 that selects the nozzle stocker according to the contents stored therein is the stocker information using unit or stocker. / The nozzle stocker selection part as a nozzle information utilization part is comprised.

  When there is no corresponding nozzle stocker, an empty nozzle stocker is attached to the mounting module, and the suction nozzle is transported by the nozzle transport plate 900 and stored in the nozzle stocker. The nozzle storage plate 900, the nozzle holding head 40, and the portion for controlling the nozzle holding head 40 of the mounting control device 1200 to store the suction nozzle 158 and the like in the empty nozzle stocker 600 and the like constitute a nozzle storage stocker generating device or nozzle storage device. is doing.

  When the nozzle stocker 600 and the like are attached to the mounting modules 12 and 13, the shutter 622 and the like are locked by the lock device 710 except when the suction nozzle 158 and the like are exchanged with the nozzle holder 160 and the like. ing. Therefore, even when the nozzle stocker 600 or the like is removed from the mounting modules 12 and 13, the shutter 622 and the like are locked, and the operator cannot freely open the shutter 622 and the like and is stored in the nozzle stocker 600 or the like. The suction nozzle 158 or the like cannot be exchanged.

  However, it is inconvenient that the operator cannot replace the suction nozzle 158 etc. at all, and as described above, the unlocking device 1000 is provided outside the machine, and the locking action of the locking device 710 is released, The operator can open and close the shutter 622 and the like to exchange the suction nozzle 158 and the like, and the suction nozzle 158 and the like may be removed from the nozzle stocker 600 and the like by unlocking. Is detected. In other words, outside the machine, unless the locking mechanism of the locking device 710 is released using the unlocking device 1000, there is no possibility that the suction nozzle has been removed from the nozzle stocker, and it has been removed from the mounting modules 12, 13. For various nozzle stockers including the nozzle stockers 600 and 602, it is guaranteed that the nozzle storage state obtained so far has not changed.

  When an operator stores the suction nozzle 158 or the like in an empty nozzle stocker 600 or the like, or replaces the suction nozzle 158 or the like in the nozzle stocker 600 or the like in which the suction nozzle 158 or the like is already stored, these operations are displayed. This is done according to the display on the screen. For example, when the suction nozzle 158 and the like are stored in the empty nozzle stocker 600 and the like, in this embodiment, the individual identification information of the nozzle stocker that stores the suction nozzle on the display screen controlled by the host computer 1250 and the nozzle stocker. The type, number and arrangement of one or more suction nozzles to be stored are displayed. These are set in the host computer 1250 based on a mounting program or the like. The placement is indicated by, for example, a number assigned to the upper surface of the nozzle storage base 620.

  In accordance with this display, for example, the worker attaches an empty nozzle stocker 600 to the lock release device 1000 and inputs a lock release command from the input device 1012. Then, the two-dimensional code 696 provided in the nozzle stocker 600 is picked up by the image pickup device 1014, the stocker information is acquired, the locking action of the lock device 710 is released, and the operator moves the shutter 622 to the nozzle removal allowable position. The suction nozzle 158 can be accommodated according to the display.

  In the host computer 1250, based on the stocker information obtained by imaging the two-dimensional code 696, the stocker individual identification information of the attached nozzle stocker 600 is set, and whether or not it matches the instructed individual stocker identification information. A determination is made and if they do not match, this is notified and the matching nozzle stocker 600 is attached to the unlocking device 1000.

  When the nozzle stocker 600 is attached and the specified suction nozzle 158 is stored, the two-dimensional code 406 is imaged by the imaging device 1014 based on the operator's instruction, and the specified storage position (arrangement position) is specified. It is confirmed whether or not the kind of suction nozzle 158 is stored. The information reading position set for the nozzle stocker 600 is obtained from the type of the nozzle stocker 600, and the imaging device 1014 is moved to the information reading position to perform imaging. If the wrong suction nozzle 158 is stored, the storage position, the type of the suction nozzle 158 currently stored, the type of the suction nozzle 158 to be stored, and the like are displayed.

  When all of the instructed suction nozzles 158 are stored in the instructed storage position, the storage completion is displayed, the operator finishes the operation, and removes the nozzle stocker 600 from the lock release device 1000. When the storage is completed, the locking device 710 is locked, and when the nozzle stocker 600 is removed, the shutter 622 is locked. By confirming the suction nozzle 158 stored in the nozzle stocker 600, stocker nozzle storage information in which the nozzle information of the suction nozzle 158 in the nozzle stocker 600 is associated with the storage position is obtained, and the stocker / storage information associated with the individual stocker identification information is obtained. The nozzle information is stored in the stocker / nozzle information memory of the host computer 1250.

  When the nozzle stocker is replaced in order to replace the suction nozzle 158 and the like, the nozzle stocker 600 and the like are removed from the mounting modules 12 and 13 by the operator. These removals are performed in the same manner for any nozzle stocker, and the removal of the nozzle stocker 600 will be described as a representative.

  When the nozzle stocker 600 is removed, the operator retracts the nozzle stocker 600 by a small distance against the urging force of the spring 794 that urges the engagement lever 790, and in this state, the operator moves the inclined surface 650 of the positioning member 644. The nozzle stocker 600 is rotated against the urging force of the spring 794 around the engaging portion of the positioning recess 778 with the inclined surface 780, and the rear portion is lifted upward to position the positioning hole 784 with the positioning pin 774. Then, the engaging member 646 is disengaged from the engaging lever 790. Then, the nozzle stocker 600 is retracted, the positioning protrusion 649 is pulled out of the positioning recess 778, and the nozzle stocker 600 is removed from the stocker holding device 760. After the nozzle stocker 600 is removed, if the operator installs a nozzle stocker to be used next on the mounting module, individual identification information of the nostocker, information indicating the mounting module, etc. are displayed on the display screen 1236, and the operator The instructed nozzle stocker is attached to the attachment portion 610.

  Although detailed explanation is omitted because it is not directly related to the present invention, any of the suction nozzles 158 and the like is not suitable for use due to bending of the suction pipes 362 and 742 during mounting of the components on the wiring board 30. It is determined whether or not a defective nozzle 158 or the like has been reached. If it is determined that the defective nozzle 158 or the like has been reached, the suction nozzle 158 or the like is prepared in the nozzle stocker 600 or the like during the mounting operation. This is replaced with a spare suction nozzle 158 or the like that can be used and the same kind of usable suction nozzle 158 or the like. At the same time, the occurrence of a defective nozzle 158 and the like, information on the position of the defective nozzle 158 on the nozzle stocker 600 and the individual identification information of the nozzle stocker 600 and the like are stored in the host computer 1250. Then, when the nozzle stocker 600 or the like in which the defective nozzle 158 or the like is stored is used for the wiring board 30 next, the normal suction nozzle 158 or the like is transported by the nozzle transport plate 900 and replaced with the defective nozzle 158 or the like. After the mounting operation is completed, the defective nozzle may be replaced before removing the nozzle stocker 600 and the like from the mounting modules 12 and 13 for the setup change. Replacement with a non-defective nozzle such as the defective nozzle 158 may be performed by an operator. If the nozzle stocker 600 and the like are removed from the mounting modules 12 and 13 by changing the setup, etc., the host computer 1250 displays the occurrence of the defective nozzle 158 and the like, the individual identification information of the stocker, the type of the defective nozzle 158 and the storage position, etc. Let the operator exchange them.

  If the operator attaches the nozzle stocker 600 or the like to the mounting modules 12 and 13 at the time of changeover, the nozzle already stored stocker confirmation routine shown in FIG. 43 is executed. Here, the case where the nozzle stocker 600 is attached to the mounting module 12 will be described as an example. In S11 of the nozzle storage stocker confirmation routine, first, the two-dimensional code 696 of the nozzle stocker 600 is imaged by the mark imaging device 178, and the stocker information is read.

  Next, S12 is executed, and the stocker individual identification information included in the stocker information read by imaging the two-dimensional code 696 is displayed as a nozzle stocker attached to the mounting module 12, and matches the individual identification information of the designated nozzle stocker. It is determined whether or not. If they match, the determination result in S12 is YES, S23 is executed, and the suction nozzle 158 accommodated in the nozzle stocker 600 is confirmed.

  This confirmation is performed according to the suction nozzle confirmation routine shown in FIG. In S31 of this routine, it is determined whether or not there is a possibility that the shutter 622 has been opened outside the apparatus, and whether or not there is a possibility that the suction nozzle 158 has been removed from the nozzle stocker 600 outside the apparatus. Is determined. This is because the shutter 622 is always opened in order to take out, house, and replace the suction nozzle 158, and at this time, the lock of the lock device 710 is released. Therefore, the determination in S31 is performed based on whether or not the lock device 710 is unlocked by the lock release device 1000. As described above, when the lock action of the lock device 710 is released in the lock release device 1000, the individual identification information of the nozzle stocker to be unlocked is sent to the host computer 1250 and stored, and the determination in S31 Is performed based on the individual identification information of the nozzle stocker and the unlock information including that the unlock has been executed.

  The shutter 622 and the like are opened also when the operator stores the suction nozzle 158 and the like in the empty nozzle stocker 600 and the like, but in this case, the storage work of the suction nozzle 158 and the like in the empty nozzle stocker 600 and the like is performed. Since it is known in the host computer 1250 that the operation is performed, and the stocker / nozzle information is obtained by reading the suction nozzle information as described above, the lock release information is not created. If the stocker / nozzle information can be obtained even if the shutter 622 is unlocked, the lock release information is created to indicate that the suction nozzle may have been taken out, and the existing stocker / nozzle information. It is not necessary to show that the information may be different from the actual information.

  In other words, even with the nozzle stocker 600 or the like for which unlock information has been created, if the suction nozzle information is read and the nozzle / stocker information representing the actual suction nozzle storage information is obtained, the unlock information is deleted. be able to. In order to change the storage state of the suction nozzle 158 and the like in the nozzle stocker 600 and the like, it is necessary to unlock the lock device 710, and after the lock is released, the suction nozzle information is read (imaging the two-dimensional code 406). If the actual storage state of the suction nozzle 158 in the nozzle stocker 600 or the like cannot be obtained, the fact that the lock is released is stored, the shutter 622 or the like is opened, and the suction nozzle 158 or the like is opened. It is necessary to memorize that there is a possibility that it has been taken out, but if the suction nozzle information is read, reliable stocker / nozzle information can be obtained. Often, unlock information can be deleted.

  Further, when replacement of the suction nozzle 158 or the like stored in the nozzle stocker 600 or the like is performed based on an instruction of the host computer 1250, storage of the suction nozzle 158 to be replaced such as the nozzle stocker 600 or the like in which the suction nozzle 158 or the like is replaced. The position, the type of the suction nozzle 158 stored in the nozzle stocker 600 or the like instead of the currently stored suction nozzle 158, and the like are displayed on the display screen and instructed. In this case, in the same manner as when the suction nozzle 158 or the like is stored in the empty nozzle stocker 600 or the like, the nozzle stocker 600 or the like is confirmed and replaced according to the instruction, and the two-dimensional code 406 or the like of the suction nozzle 158 or the like stored. Is picked up, the suction nozzle information is read, and the designated suction nozzle 158 and the like are stored in the designated position. As a result, the host computer 1250 updates the stocker / nozzle information, obtains stocker / nozzle information corresponding to the actual storage state, and does not create unlock information.

  For example, when the operator sets the nozzle stocker 600 or the like in the lock release device 1000 and releases the lock without being instructed by the host computer 1250, it does not matter whether the suction nozzle 158 or the like is actually replaced. The suction nozzle information is not read, the stocker / nozzle information is not updated, and the host computer 1250 creates lock release information. In response to an instruction from the host computer 1250, the nozzle stocker 600 or the like is set in the unlocking device 1000. However, the unlocking information is also generated when the suction nozzle 158 or the like is not replaced and the stocker / nozzle information is not updated. .

  Note that even when the suction nozzle 158 and the like are exchanged according to an instruction from the host computer 1250, the suction nozzle information of the exchanged suction nozzle 158 may not be read, and the stocker / nozzle information is updated. If not, unlock information is created.

  If the unlock information is not created, the determination result in S31 is NO and the execution of the routine ends. In this case, the stocker / nozzle information currently stored in the stocker / nozzle information memory is used as information on the stocker nozzle 600 attached to the mounting module 12. For the nozzle stocker 600 or the like for which unlock information has not been created, you may be confident that the stocker / nozzle information obtained for it is consistent with the actual nozzle storage state, and is stored in the stocker / nozzle information memory. The information can be used for wearing.

  If the shutter 622 is unlocked outside the apparatus and the unlock information is created, the determination result in S31 is YES, S32 is executed, and the suction nozzle information is read. Based on the type of nozzle stocker 600 and the like recorded in the stocker information, the information reading position set corresponding to each of the plurality of nozzle storage holes 624 and the like is read from the host computer 1250, and the mark imaging device 178 reads the information reading position. The two-dimensional code 406 and the like are imaged and nozzle information is read. The information reading position may be sent from the host computer 1250 to the mounting control computer 1210 and stored in advance. When imaging the two-dimensional code 406 and the like, the nozzle stocker 600 and the like are positioned at the second position in the height direction. In addition, the stocker reference mark 698 of the nozzle stocker 600 is read by the mark image pickup device 178, and the mounting position error of the nozzle stocker 600 is acquired and corrected when the two-dimensional code 406 is picked up. Also at this time, the nozzle stocker 600 is positioned at the second position. This correction may be omitted when the attachment position error is smaller than the set value. Then, the mark imaging device 178 is moved to all information reading positions set in the nozzle stocker, performs imaging, reads nozzle information, obtains stocker nozzle storage information, and associates it with the stocker individual identification information. Nozzle information is obtained and stored in each stocker / nozzle information memory of the mounting control computer 1210 and the host computer 1250. If the suction nozzle 158 or the like is not stored and an image such as the two-dimensional code 406 is not obtained, information indicating that the suction nozzle 158 is not stored is created. If an image such as the two-dimensional code 406 is not obtained, the presence / absence of the suction nozzle 158 or the like is detected, and if so, imaging may be performed by changing the imaging position, or information acquisition may be performed by informing that fact. You may stop.

  If the two-dimensional code 406 is imaged for all the suction nozzles 158 of the nozzle stocker 600 and the information is read, S33 is executed, and the unlock information created for the nozzle stocker 600 is deleted. Stocker individual identification information and unlock release deletion information are sent to the host computer 1250 and deleted by the host computer 1250. Next, S34 is executed, and it is determined whether or not there is a change in the suction nozzle 158 stored in the nozzle stocker 600. Stocker nozzle storage information obtained by imaging the two-dimensional code 406 of the suction nozzle 158, the stocker nozzle storage information stored in the stocker / nozzle information memory of the host computer 1250 and the mounting control computer 1210 in association with the individual identification information of the stocker And whether or not at least one of the type, number, and storage position of the suction nozzle 158 has been changed is determined.

  If there is no change in the type, number, or storage position of the suction nozzles 158 stored in the nozzle stocker 600, the determination result in S34 is NO and the execution of the routine ends. As a result, the nozzle stocker confirmation routine is also completed, and the attachment of the circuit component 25 to the wiring board 30 is started using the suction nozzle 158 housed in the nozzle stocker 600 attached to the mounting module. Is done.

  If at least one of the type, number, and storage position of the suction nozzle 158 stored in the nozzle stocker 600 has been changed, the determination result in S34 is YES and S35 is executed, and by reading the suction nozzle information in S32 The obtained stocker nozzle storage information is stored in the stocker / nozzle information memory in association with the stocker individual identification information in place of the stocker / nozzle information stored so far.

  Next, S36 is executed to determine whether or not the mounting operation can be performed. It is determined whether or not the work of mounting the circuit component 25 on the wiring board 30 can be performed by the suction nozzle 158 housed in the nozzle stocker 600 actually attached to the mounting module. A mounting in which the nozzle stocker 600 and the like are mounted by the suction nozzle 158 stored in the nozzle stocker 600 based on the stocker nozzle storage information obtained by imaging the two-dimensional code 406 and the information obtained from the component mounting program. It is determined whether or not the circuit component 25 assigned to the modules 12 and 13 can be mounted on the wiring board 30.

  If the mounting work can be performed, the determination result in S36 is YES, S37 is executed, and data necessary for calculating the work time is sent to the host computer 1250. The work time is a time required when a mounting operation to be actually performed is performed by the suction nozzle 158 accommodated in the nozzle stocker 600 that is currently attached, and the work time of the suction nozzle 158 accommodated in the nozzle stocker 600 is determined. Data such as the type, number and storage position, type of wiring board 30, component mounting position, circuit component 25, etc. are sent to the host computer 1250, and the execution of the routine is completed. If information related to the type of the wiring board 30 is stored in the host computer 1250, it is not essential to transmit such information.

  On the other hand, if the attachment work cannot be performed by the suction nozzle 158 housed in the nozzle stocker 600 that is currently attached, the determination result in S36 is NO and S38 is executed, and attachment as trouble information is performed. Work impossibility information is created and displayed on the display screen 1236 to notify the worker. The mounting work execution impossibility information includes, for example, individual identification information and type information of the nozzle stocker 600 that is attached to the mounting module but cannot be used in the mounting work. In accordance with this notification, the worker replaces the nozzle stocker 600, for example.

  If the individual identification information of the instructed nozzle stocker does not match the individual identification information of the actually installed nozzle stocker in S12 of the nozzle already stored stocker confirmation routine, S13 is executed and stocker difference information is created. The Next, if S14 is executed in the same manner as S31, the unlock information has been created, and there is a possibility that the shutter 622 has been opened outside the machine, the determination result in S14 is YES, and S15 to S19, S21 is executed in the same manner as S32 to S36 and S38, and nozzle information is read by imaging the two-dimensional code 406. Accordingly, for example, even if a nozzle stocker different from the instructed nozzle stocker 600 is attached to the mounting module, if the suction nozzles stored in the nozzle stocker are confirmed, the mounting operation can be performed. The working time is calculated. If this is not possible, this will be notified.

  If a nozzle stocker different from the instructed nozzle stocker 600 is attached, but there is no possibility that the shutter has been opened, the determination result in S14 is NO, S22 is executed, and nozzle information is acquired. The Here, based on the stocker individual identification information and the stocker / nozzle information stored in the stocker / nozzle information memory, the stocker nozzle storage information stored in association with the stocker individual identification information is read from the stocker / nozzle information memory. Then, S19 is executed, and it is determined whether or not the mounting operation can be performed based on the read nozzle information.

  When the work time calculation data is transmitted, the host computer 1250 calculates the work time and transmits the calculation result to the mounting control computer 1210. In the mounting control computer 1210, a required work time determination routine shown in FIG. 45 is executed. In S61 of this routine, it is determined whether or not the operation time calculation has been completed. It is determined whether or not the work time calculated from the host computer 1250 has been transmitted. If it has not been transmitted, the determination result in S61 is NO and the execution of the routine is terminated.

  When the calculation of the work time is completed and transmitted to the mounting control computer 1210, the determination result in S61 is YES, S62 is executed, and it is determined whether the required work time is excessive. This determination is made based on whether or not the required work time exceeds the set work time. If the required work time is less than or equal to the set work time, the determination result in S62 is NO and S63 is executed, and data that permits execution of the mounting work Is created. Thereby, in the mounting module, the mounting of the circuit component 25 to the wiring board 30 can be started.

  If the required work time exceeds the set work time, the determination result in S62 is YES and S64 is executed, and the work time excess information indicating that is displayed on the display screen 1236 to notify the worker. The fact that the nozzle stocker is different from that instructed, the type of nozzle stocker actually attached, individual identification information, the type of nozzle stocker actually instructed, individual identification information, etc. are notified. In accordance with this notification, the worker performs appropriate processing such as replacing the nozzle stocker 600 with another nozzle stocker 600, for example.

  When the nozzle holding head 40 mounts the circuit component 25 on the wiring board 30, the circuit component 25 is received from the component supply device 24, but when it is received in a standing position, the circuit component 25 is transferred to the component storage device 1070. It is thrown away and is not attached to the wiring board 30. In this component housing apparatus 1070, at least the circuit component mounted on the wiring board 30 in the mounting modules 12 and 13 by fitting the partition plate 1080 into the positioning groove 1078 provided in the housing recess 1076 by the operator. The same number of accommodation chambers 1072 as 25 types are provided. As described above, the fitting operation of the partition plate 1080 is performed by an operator based on an instruction from the host computer 1250, for example, and a plurality of types of sizes can be accommodated according to the size of the circuit component 25 and the number of mounted components. The required number of chambers 1072 is provided. Further, by reading the mark 1084 during the fitting operation of the partition plate 1080, information on the arrangement and the like of the storage chamber 1072 is obtained.

  The component storage device 1070 is attached to one of the plurality of attachment portions 610 of the mounting modules 12 and 13 in the same manner as the nozzle stocker 600 and the like. In a state of being positioned by the stocker positioning device 766, it is fixed to the stocker holding base 764 by the stocker fixing device 768 and supported from below by the support member 820 or the like. When the component storage device 1070 is attached to the attachment portion 610, the mark imaging device 178 is moved, the two-dimensional code 1082 is imaged, and the component storage device information is acquired. Further, the mark imaging device 178 images the mark 1084 provided on the partition plate 1080, acquires the position of the partition plate 1080, and acquires storage chamber information such as the size and arrangement of the storage chamber 1072. The positioning grooves 1078 are provided at an equal pitch in the longitudinal direction of the receiving recess 1076, and the mark imaging device 178 is moved by a distance equal to the positioning groove forming pitch to capture the mark. This storage room information is information about the actual storage room of the component storage device 1070 in a state attached to the mounting module, and is stored in the RAM 1216 of the mounting control computer 1210 in association with the component storage device information.

  The component storage device information includes information indicating that the component storage device 1070 is a component storage device, and the component storage device 1070 is attached to the attachment portion 610 based on the acquired component storage device information. It is confirmed whether or not. Further, the storage room information stored in the host computer 1250 in association with the individual identification information of the component storage device 1070 when the partition plate 1080 is fitted is read based on the individual identification information of the component storage device 1070. It is compared with the storage room information acquired after the attachment of 1070 to the mounting module. If the actual storage room information is inconsistent with the stored information and the number, size, arrangement, etc. of the storage room 1072 are inappropriate, this is displayed and notified. In accordance with this notification, the operator reinserts the partition plate 1080. Thereby, even if the attachment position may be changed after the partition plate 1080 is once attached, the storage chamber 1072 set in advance for the component storage device 1070 is obtained.

  When the circuit component 25 taken out from the component supply device 24 is imaged by the component imaging device 50 and, as a result, it is determined that the circuit component 25 is not mounted on the wiring board 30 and discarded in the component housing device 1070, the nozzle holding head 40 The waste circuit component 25 is moved to the component storage device 1070 and placed in the storage chamber 1072 corresponding to the type of the circuit component 25. The circuit component 25 to be accommodated for each accommodation room 1072 is set based on the accommodation room information acquired previously. Further, the number of circuit components 25 accommodated in each accommodation chamber is counted and stored together with the data specifying the type and the accommodation chamber 1072 (for example, the position in the component accommodation device 1070). These data are sent to the host computer 1250 and stored in the component storage device information memory in association with the individual identification information of the component storage device 1070.

  If the component accommodating device 1070 is also changed at the time of changing the setup after the completion of the mounting operation, the operator removes the component accommodating device 1070 in which the circuit component 25 is accommodated from the mounting modules 12 and 13. Then, the circuit component 25 accommodated in the accommodation chamber 1072 is taken out, and the reusable circuit component 25 is selected and used. At this time, for example, if the worker inputs the individual identification information of the component storage device 1070 that processes the discarded component 25, the individual identification information and storage chamber information of the component storage device 1070 are displayed on the display screen controlled by the host computer 1250. The type, number, etc. of the accommodated circuit components 25 are displayed, and the operator can easily perform the work by looking at the display. For example, it can be determined which of the plurality of storage chambers 1072 contains the circuit component 25, and the processing of the stored circuit component 25 can be performed quickly.

  In addition, when the component storage device is such that the partition plate is not removable and the size, number, arrangement, etc. of the storage chamber are unique to the component storage device, for example, individual identification information as the component storage device information In addition, the storage room information can be stored, and the information can be acquired by reading the two-dimensional code and used for discarding the circuit components. Alternatively, the storage room information is stored in the host computer in association with the individual identification information of the device, the storage room information is not stored in the two-dimensional code, and the storage room information is obtained from the individual identification information obtained by reading the component storage device information. You may make it obtain.

  If the electrical characteristics of the circuit component 25 is detected before the nozzle holding head 40 receives the circuit component 25 received from the component supply device 24 on the wiring board 30, the component electrical property measuring device 1030 is attached to the attachment portion 610. It is done. The mounting modules 12 and 13 are each attached to any one of a plurality of mounting portions 610. It is preferable that the mounting portions 610 are attached to the mounting portions 610 that can move the nozzle holding head 40 as little as possible. This attachment is performed in the same manner as the attachment to the attachment portion 610 of the nozzle stocker 600 or the like.

  After the component electrical property measuring apparatus 1030 is attached, the two-dimensional code and the reference mark provided thereon are imaged by the mark imaging device 178, and the component electrical property measuring device information and the attachment position error are acquired. Further, based on the component electrical property measurement device information, whether or not the device attached to the attachment portion 610 is the component electrical property measurement device 130 and whether or not the specific component electrical property measurement device 130 is attached is instructed. For example, it is confirmed whether or not the device 130 is actually attached, and if the wrong device or another component electrical property measuring device 130 is attached, that fact is displayed and replaced. Can do.

  After the circuit component 25 is taken out from the component supply device 24, the nozzle holding head 40 is moved to the component electrical property measuring device 1030 before or after the imaging by the component imaging device 50, and the electrical characteristics of the circuit component 25 are changed. Measured. The movement position of the nozzle holding head 40 is corrected so that the mounting position error of the component electrical property measuring apparatus 1030 is eliminated, and the circuit component 25 is accurately positioned between the pair of probes 1036, and the electrical property is measured. Based on the measurement result, for example, whether the circuit component 25 is good or bad is determined, and if the circuit component 25 is a defective component or the wrong type, the circuit component 25 is stored in the component storage device. 1070 and is not attached to the wiring board 30.

  If the type of the circuit component 25 is wrong, the feeder 26 that supplied the circuit component 25 is stored, for example, according to the mounting position on the feeder pallet, displayed on the display screen 1236, and notified to the operator. If the type is wrong even though the circuit component 25 is received from the feeder 26 set in the component mounting program, the type of the circuit component 25 held by the feeder 26 may be wrong. It is done. The supply of the circuit component 25 in the feeder 26 is performed, for example, by splicing the electronic circuit component taping, and the tip of the new electronic circuit component taping is connected to the end of the electronic circuit component taping that is actually supplying the circuit component 25. If the circuit component 25 is replenished, it is presumed that the connected new electronic circuit component taping is wrong, and the feeder 26 is checked. If it is wrong, the feeder 26 is replaced, splicing is performed again, etc. Appropriate processing is performed to prevent the wrong type of circuit component 25 from being attached to the wiring board 30.

  The measurement result of the electrical characteristics of the circuit component 25 corresponds to the component electrical property measurement device information in the RAM 1216 of the mounting control computer 1210 together with the data specifying the type of the circuit component 25, the feeder 26 that supplied the circuit component 25, and the like. It is memorized. The measurement history information of the component electrical property measuring apparatus 1030 is created. Since the device information includes information for individually identifying the component electrical property measuring device 1030, no matter which component electrical property measuring device 1030 is attached to any of the mounting modules 12 and 13, the individual component electrical property measurement is performed. A measurement history can be created for the device 130. Thereby, for example, when there are many abnormalities in the measurement results for a specific component electrical property measuring apparatus 1030, it can be estimated that some abnormality has occurred in the apparatus 1030. Moreover, when many abnormality of the measurement result has arisen about the specific circuit component 25, it can also be estimated that there is an abnormality in the circuit component 25.

  When the circuit component 25 mounted on the wiring board 30 has solder bumps and the flux is applied, the dip type flux applying device 1050 is attached to one of the plurality of attaching portions 610. This attachment is performed in the same manner as the attachment of the nozzle stocker 600 and the like. After the attachment, the two-dimensional code 1066 is imaged and the flux application device information is acquired. As a result, information on the size and arrangement of the flux receiving recess 1054 and the like of the flux application device 1050 and individual identification information can be obtained, and it can be confirmed whether or not the flux application device 1050 is attached to the attachment portion 610. . After receiving the circuit component 25 from the component supply device 24, the nozzle holding head 40 is moved to a flux accommodating recess suitable for the held circuit component 25 among the three flux accommodating recesses 1054, 1056, and 1058, and is lowered. Then, flux is applied to the solder bumps.

  Further, the number of times of flux application to the solder bump is stored for each of the three flux receiving recesses 1054, 1056, and 1058, and the mounting control computer 1210 and the host computer 1250 are associated with the application device individual identification information and the type of the flux receiving recess. Stored in each memory. As a result, the flux application device 1050 is used in a plurality of different mounting modules, or is used in the same mounting module, but each of the three flux receiving recesses 1054, 1056, and 1058 is used even if the use time is not continuous. The total number of flux application can be obtained for, for example, the remaining amount of flux is estimated, and if a flux containing recess with a remaining amount less than the set amount occurs, the replenishment of the flux is instructed, The use of the flux application device 1050 having the flux accommodating concave portion can be prohibited, or replacement can be instructed. These replenishment and replacement instructions and use prohibition are performed using the individual identification information of the coating device, and the flux coating device that needs to be replenished can be specified. Further, the flux application device used in the mounting module can be indicated by the individual identification information.

  When one of the mounting modules 12 and 13, for example, the mounting module located at the most upstream in the wiring board conveyance direction, is attached with an adhesive application head 1100 instead of the nozzle holding head 40 and functions as an adhesive application module Will be explained. In this case, the trial hitting device 1120 is attached to one of the plurality of attachment portions 610. This attachment is performed in the same manner as the attachment of the nozzle stocker 600 and the like, and after the attachment, the mark image pickup device 178 picks up the two-dimensional code 1126 and reads the test hitting device information. Thereby, for example, it can be confirmed whether or not the trial hitting device 1120 is attached to the attachment portion 610.

  Before the adhesive application head 1100 applies the adhesive to the wiring board 30, the test hitting surface 1124 is thrown away and the test hitting is performed. A discard hitting position or the like is set in advance on the test hitting surface 1124, and the adhesive application head 1100 performs the discard hitting and the test hitting a preset number of times. The number of times of discarding performed on the trial hitting surface 1124 is counted and stored in association with the trial hitting device individual identification information. If the number of times becomes equal to or greater than the set number, the operator is instructed to clean the test hitting surface 1124. This instruction may be instructed by the trial hitting device individual identification information. If the trial hitting device 1120 is attached to the mounting portion 610, it may be indicated by the mounting module, or may be indicated by both. .

  Individual identification information is set for the suction nozzle 158 and the like, and the individual identification information is used as necessary. For example, the suction nozzle 158 stored in the nozzle stocker 600 or the like is instructed by the individual identification information. Alternatively, a defective suction nozzle 158 that cannot be used may be notified.

As is apparent from the above description, in the present embodiment, the mark imaging device 178 constitutes a stocker information reading device, a stocker individual identification information reading device, and a nozzle information reading device. Further, the illumination device 192 constitutes an ultraviolet irradiation device, the CCD camera 190 constitutes a visible light detection device, and together with the fluorescent layers 634 and 734 constitute a nozzle presence / absence detection device.

Constitutes a stocker position acquisition unit. Both the nozzle presence / absence detection device and the nozzle information reading device use imaging by the mark imaging device 178 and share a part of the configuration. However, the nozzle presence / absence detection device includes the fluorescent layers 634 and 734, and at the time of detection and reading. The color of the illumination light at the time is different, and the nozzle information reader is provided separately from the nozzle presence / absence detector.
The part of the mounting control device 1200 that controls the holding device lifting / lowering device 762 according to the type of the nozzle holding head 40 constitutes a stocker height control unit, and together with the holding device lifting / lowering device 762 constitutes a stocker height changing device. The lock device 710 constitutes a manual removal prevention device and an external nozzle removal prevention device as the nozzle removal prevention device. Furthermore, the part that executes S11 of the mounting control device 120 and the mark imaging device 178 constitute a stocker information acquisition device, and the part that executes S38 constitutes a mounting work infeasible information creation unit as a trouble information creation unit. . The part that calculates the required work time of the host computer 1250 constitutes the required time calculation part, the part that executes S64 of the mounting control device 1200 constitutes the excessive time display part, and these also constitute the trouble information creation part Yes. Furthermore, the part which performs S22 of the mounting | wearing control apparatus 1200 comprises the nozzle type information acquisition part.
Further, the part of the host computer 1250 that stores the unlock information in the unlock information memory based on the information transmission from the unlock control computer 1010 is a kind of nozzle extraction possibility detection device, and the suction from the nozzle stocker 600 or the like. A shutter lock release detection device, which is a kind of operation detection device at the time of taking out the nozzle, detects the possibility that the suction nozzle 158 etc. is taken out by detecting an operation or operation that is always performed with the removal of the nozzle 158, etc. is doing.
Furthermore, the part that executes S15, S22, S31, and S32 of the mounting control device 1200, and the part that obtains nozzle information based on the individual stocker identification information and the stocker / nozzle information apart from these constitutes the nozzle type information obtaining unit. , S13 executes the stocker difference information creation unit, and S15 and S22 execute the nozzle information acquisition device.

  In the above embodiment, the lock device 710 and the lock release device 1000 are provided to prevent the operator from taking out the suction nozzle from the nozzle stocker. If the lock release device 1000 is used, the lock is released and the suction nozzle is set to the nozzle. Whether or not the suction nozzle 158 or the like has been taken out from the nozzle stocker 600 or the like is detected depending on whether or not the lock of the shutter 622 or the like by the lock release device 1000 is released. However, the presence / absence of the possibility of nozzle removal may be detected based on whether the shutter is opened or closed. The embodiment will be described with reference to FIGS.

  In the electronic circuit component mounting machine of the present embodiment, as shown in FIG. 46, a tag chip 1502 which is a kind of electronic tag is provided in a nozzle stocker 1500 to constitute a stocker information recording unit. As shown in FIG. 47, the tag chip 1502 mainly includes a memory 1510, a communication circuit 1512 for wireless communication, and a logic circuit 1514 that connects them. The tag chip 1502 includes an antenna and transmits information recorded in the memory 1510 by wireless communication to a reader / writer 1520 as an information receiving / writing device which is a kind of information acquisition device, or the received information is stored in the memory 1510. Can be recorded. In this embodiment, the tag chip 1502 can read and write information, and the information transmission method is, for example, an electromagnetic induction method.

  Stocker information is recorded in the memory 1510 of the tag chip 1502. The stocker information includes, for example, individual stocker identification information that is information for individually identifying the nozzle stocker, and stocker type information for identifying the type of the nozzle stocker. Further, information stored in the host computer in association with the type of nozzle stocker in the embodiment, such as the position of the nozzle storage hole 624, may be stored in the host computer, but is recorded in the tag chip. .

  The tag chip 1502 includes a pressure sensor 1524 in this embodiment. The nozzle stocker 1500 is configured, for example, in the same manner as the nozzle stocker 600, and the tag chip 1502 is embedded in a recess 1527 (see FIG. 48) provided in the nozzle storage base 1526. As shown in FIGS. 46 and 48, the shutter 1528 is provided with an opening 1529. As shown in FIG. 48A, the tag chip 1502 is placed in the opening 1529 in a state where the shutter 1528 is located at the nozzle removal preventing position. The information is read by the reader / writer 1520.

  The shutter 1528 is provided with another opening 1530, and a pressurizer or contact 1532 provided in the shutter 1528 is fitted into the opening 1530. In this embodiment, the contact 1532 is made of a leaf spring, which is a kind of elastic member. One end in the longitudinal direction is fixed to the upper surface of the shutter 1528, and the other end is curved convexly toward the nozzle storage base 1526. It is inserted into the opening 1530 and brought into contact with the nozzle storage base 1526.

  As shown in FIGS. 46 and 48 (a), in the state where the shutter 1528 is positioned at the nozzle removal preventing position, the contact 1532 is detached from the tag chip 1502 and is elastically brought into contact with the upper surface of the nozzle storage table 1526. As shown in FIG. 48 (b), in a state where the shutter 1528 is located at the nozzle take-out allowable position, the contact 1532 reaches the tag chip 1502 and pushes the tag chip 1502. As a result, the pressure detected by the pressure sensor 1524 increases to exceed the set value, and it is detected that the shutter 1528 has been moved to the nozzle removal allowable position, and this is stored in the memory 1510. Even if the shutter 1528 is moved to the nozzle take-out allowable position, the suction nozzle 158 is not necessarily taken out or replaced, but it is stored as a possibility.

  The reader / writer 1520 is provided on the second X slide of the head moving device that moves the nozzle holding head 40 together with the nozzle holding head 40 and the mark imaging device 178, and is moved to an arbitrary position in the horizontal plane. Information read by the reader / writer 1520 is input to the mounting control computer 1210.

  If the nozzle stocker 1500 is attached to the mounting module, the reader / writer 1520 is moved to communicate with the tag chip 1502 and receive information stored in the memory 1510. The nozzle already stored stocker confirmation routine is executed. If the storage nozzle confirmation routine is executed, the determination as to whether or not the shutter has been opened outside the apparatus in S31 is based on the information stored in the tag chip 1502. If it is stored and it is stored that the shutter 1528 has been opened, the determination result in S31 is YES, and the steps from S32 are executed. The determination in S14 is also made based on the information stored in the memory 1510.

  When a series of mounting operations are completed and the nozzle stocker 1500 is removed from the mounting module, the shutter opening information stored in the memory 1510 of the tag chip 1500 is deleted. Of course, it is not stored in the memory 1510 that the shutter 1528 is opened when the nozzle stocker 1500 is attached to the mounting module. However, the shutter 1528 is used for the transfer of the suction nozzle 158 during the mounting operation. Is opened and closed, and it is detected that the shutter 1528 is opened. In this case as well, shutter opening information is not left in the memory 1510, and the shutter 1528 used in the nozzle storage stocker confirmation routine is used. The information regarding the presence / absence of opening / closing of the shutter 1528 is information regarding the presence / absence of opening / closing of the shutter 1528 when the nozzle stocker 1500 is outside the apparatus.

Since the opening and closing of the shutter 1528 is detected in the nozzle stocker 1500 itself, and the possibility that the operator can take out the suction nozzle is detected and stored, as in the above embodiment, the shutter of the shutter by the unlocking device is used. It is not necessary to memorize the unlocking. Therefore, the locking device and the unlocking device need not be provided, but may be provided. However, in this case, it is not essential to create unlock information.
In the present embodiment, the pressure sensor 1524 constitutes a shutter open / close detection device as a nozzle extraction possibility detection device.

  In the present embodiment, a tag chip is also provided for the suction nozzle and constitutes a nozzle information recording unit. This tag chip is a tag chip capable of reading and writing information, and information is read and written by a reader / writer 1520. Therefore, for example, information on the suction nozzle obtained during mounting, for example, the number of component mounting times, the number of errors, and the like can be stored. However, the suction nozzle may be provided with a two-dimensional code as a nozzle information recording unit. When the suction nozzle storage pitch in the nozzle stocker is small, if a tag chip is provided for the suction nozzle, the tag chip of the suction nozzle adjacent to the suction nozzle that acquires information when the reader / writer receives information recorded in the memory An information transmission method that does not perform communication is adopted, and an electromagnetic induction method with a short maximum communication distance or a further shorter electrostatic coupling method is adopted.

  As shown in FIG. 49, if the tag chip 1550 includes the proximity sensor 1552, it can be detected that the shutter 1556 of the nozzle stocker 1554 is opened without contact. As shown in FIG. 50, the tag chip 1550 is embedded in a recess 1560 provided in the nozzle storage base 1558, and an opening 1562 is provided in the shutter 1556.

  In a state where the shutter 1556 is positioned at the nozzle removal prevention position, the opening 1562 is positioned on the tag chip 1550 and the stocker information stored in the tag chip 1550 is read by the reader / writer 1520 as shown in FIG. . In a state where the shutter 1556 is positioned at the nozzle removal allowance position, as shown in FIG. 50B, the opening 1562 is detached from the tag chip 1550, and the tag chip 1550 is covered with a portion where the opening 1562 of the shutter 1556 is not provided.

  Accordingly, the proximity sensor 1552 does not detect the shutter 1556 when the shutter 1556 is positioned at the nozzle extraction preventing position, and detects the shutter 1556 when it is positioned at the nozzle extraction allowable position. The proximity sensor 1552 detects the movement of the shutter to the nozzle extraction prevention position and the movement to the nozzle extraction allowable position, and when the shutter 1556 is opened, the information is stored in the memory 1510.

  Note that an input terminal may be provided on the tag chip to connect a sensor, and for example, a signal of a detection device that detects opening / closing of a shutter may be input to store shutter opening / closing information.

  Further, in the above-described embodiment, it has been made possible for an operator to perform storage of the suction nozzle in an empty nozzle stocker or replacement of the suction nozzle in the nozzle stocker outside the machine, but it is not essential. All may be performed automatically. In this case, the storage state of the suction nozzle is not arbitrarily changed by the operator, and automatic storage, replacement, etc. are all grasped by the apparatus itself, so that stocker / nozzle information is obtained. If it is obtained, the stocker nozzle storage information can be obtained from the stocker / nozzle information without reading the suction nozzle information stored in the nozzle stocker. This does not preclude reading the information of the suction nozzles stored in the nozzle stocker if necessary.

  Furthermore, the information recording unit of the suction nozzle is only required to be provided at a position where information can be read at least in a state where the shutter is positioned at the nozzle extraction allowable position, and even when the shutter is positioned at the nozzle extraction prevention position. It is not essential to provide a readable position.

  Further, the nozzle conveying member may be able to exchange suction nozzles with a plurality of types of nozzle holding heads. For example, in one nozzle transport member, the thickness of the nozzle storage member is differentiated into a plurality of types, and the suction nozzle held by the nozzle holding head is stored in a storage portion having a thickness according to the type of the nozzle holding head, The suction nozzle can be exchanged with a plurality of types of nozzle holding heads having different vertical positions when the suction nozzle is exchanged.

  Furthermore, even if the types of nozzle holding heads are different, if the suction nozzles are exchanged with the nozzle holding heads at the same height, the thickness of the nozzle storage member can be changed to a plurality of types in one nozzle transport member. Without differentiating, it is possible to accommodate suction nozzles held by a plurality of types of nozzle holding heads. At this time, the nozzle housing hole has a shape and a size corresponding to the type of the suction nozzle. As described for the nozzle stockers 600 and 602, the shutters have different relative positions with respect to the suction nozzles when preventing separation of the suction nozzles according to the types of the suction nozzles, and different types of shutters are arranged by a common shutter moving device. By moving the shutter, the shutter is moved to a nozzle removal allowance position and a nozzle removal prevention position. Even if different types of suction nozzles are used, the distance of movement of the shutter is the same. Even if different types of suction nozzles are stored in a single nozzle storage member, they are covered by the same shutter, and the same distance of the shutter is used. By moving, any kind of suction nozzle can be allowed to be taken out or blocked.

  Further, when the suction nozzle is stored in the empty nozzle stocker by the nozzle holding head, the presence or absence of the suction nozzle in the nozzle storage hole may be detected. If the nozzle storage hole is empty, the suction nozzle is stored. If the nozzle storage hole is not empty, for example, the storage order is shifted one by one, and the suction nozzle is stored in the nozzle storage hole scheduled to be stored next. Alternatively, the suction nozzles may not be stored in all the nozzle storage holes of the nozzle stocker, but if there are spare empty nozzle storage holes, they may be stored in the nozzle storage holes. In this case, the notification device may notify that the suction nozzle is stored in the empty nozzle storage hole, and nozzle information recorded in the two-dimensional code of the stored suction nozzle is displayed by the information acquisition device. If it can be acquired and used for mounting, it may be used.

  The stocker lifting device is a device that uses an electric rotary motor, which is a kind of electric motor, for example, a servo motor with an encoder as a drive source. For example, the rotation of the stocker is lifted and lowered by a motion conversion device including a screw shaft and a nut. It is good also as an apparatus which converts into a motion, moves a nozzle stocker to arbitrary positions in an up-down direction, and raises / lowers.

  Furthermore, if the nozzle stocker is held by the stocker holding device and is located at the first position, if the upper surface of the nozzle storage base is located at the same height as the component mounting surface of the circuit board, the upper surface of the nozzle stocker is A code or a stocker reference mark may be provided to set the first position as the imaging position.

  Further, the rotational position error of the nozzle stocker may be acquired based on the imaging of the stocker reference mark, and may be corrected when the nozzle is stored or received.

  Further, a two-dimensional code or an electronic tag constituting the stocker information recording unit may also serve as a stocker reference mark.

  An information recording unit such as a two-dimensional code may be provided on the shutter of the nozzle stocker.

  In the above-described embodiment, the mark imaging device 178 that images the wiring board reference mark also serves as an information reading device that images the two-dimensional code 406 and the like to read information. However, a dedicated information reading device may be provided. Good. This information reading device may be moved by a nozzle holding head moving device or may be moved by a dedicated moving device.

  Further, the electronic circuit component mounting machine is not limited to the so-called XY robot type electronic circuit component mounting machine in which the nozzle holding head is moved to an arbitrary position in the XY coordinate plane by the holding head moving device, and another form of electronic circuit A component mounting machine, for example, an electronic circuit component mounting machine of a head turning type such as an index table type (also referred to as a rotary type) may be used. The index table type electronic circuit component mounting machine includes a rotating body and a rotating body rotating device that rotates the rotating body, and at least each of a plurality of nozzle holding heads held by the rotating body holds the rotating body by rotating the rotating body. One of the suction nozzles is sequentially moved to a plurality of stop positions, receives an electronic circuit component from the component supply device at the component receiving position, and mounts the electronic circuit component on the circuit board at the component mounting position. At this time, the substrate holding device is moved by the substrate holding device moving device, and the component mounting position of the circuit board is positioned at a position corresponding to the suction nozzle positioned at the component mounting position. The rotating body and the rotating body rotating device constitute a head turning device, and together with the substrate holding device moving device, constitute a relative moving device that relatively moves the nozzle holding head and the substrate holding device. In some of the head rotating type electronic circuit component mounting machines, a plurality of nozzle holding heads are respectively provided on a plurality of rotating members that can rotate independently of each other around a common rotating axis. Each of the plurality of turning members is provided with a turning motion imparting device that makes a round around the pivot axis and includes a stop at least once during the round and has a certain time difference from each other. The In the head turning type electronic circuit component mounting machine, the component supply device includes, for example, a plurality of feeders arranged side by side in the X-axis direction, and feeder movement as a relative movement device that moves the feeders in the X-axis direction. And a device. The plurality of nozzle holding heads and the head turning device are further moved by the moving device to arbitrary positions in a plane parallel to the surface of the circuit board, and the circuit board holding device and the component supply device are provided with fixed positions. It may be.

  The electronic circuit component mounting machine may be a device in which the nozzle holding head is moved by the holding head moving device in a direction parallel to one of two directions orthogonal to each other in a plane parallel to the surface of the circuit board. In this case, the circuit board holding device is moved by the holding device moving device in a direction perpendicular to the moving direction of the nozzle holding head in a plane parallel to the surface of the circuit board. These holding head moving device and holding device moving device constitute a relative moving device that relatively moves the nozzle holding head and the substrate holding device. The component supply device may be moved by the component supply device moving device in the same manner as the holding device moving device, or the position where the component supply unit is positioned on the movement track of the nozzle holding head is fixed. It may be provided.
