Description

  The present invention relates to an electronic circuit component mounting machine, and more particularly to an electronic circuit component mounting machine in which a suction nozzle and a component supply tool are integrally moved with respect to a circuit substrate.

In an electronic circuit component mounting machine, for example, as described in Patent Document 1 below, a mounting unit including a bulk feeder as a component supply tool and a suction nozzle is moved by an X-axis and Y-axis with respect to a circuit board by a moving device. There is a mounting machine that is moved in the direction and mounts electronic circuit components on a circuit board. The bulk feeder and the suction nozzle are respectively provided at the parts receiving station and the parts sending station set in the mounting unit main body, and are supplied from the bulk feeder by a moving wheel provided on the mounting unit main body so as to be rotatable around the vertical axis. Electronic circuit components are moved to the suction nozzle. By rotating the moving wheel, a plurality of component holding sections formed around the axis of rotation are sequentially moved to the component receiving station, components are put from the bulk feeder, and components holding electronic circuit components are held. The compartment is moved to the component delivery station, and the electronic circuit components accommodated in the component holding compartment are sucked by the suction nozzle, and are ejected from the component holding compartment and mounted on the circuit board.
Further, Patent Document 2 discloses an electronic circuit component mounting machine in which a circuit board is moved in the X-axis direction by a relative movement device, a bulk feeder is moved in the Y-axis direction, and an electronic circuit component is mounted on the circuit board. Have been described. The bulk feeder is provided in a vertical direction on a rotating body provided to be rotatable about a vertical axis in the mounting unit main body, and is sent from the storage unit to the supply unit by the component moving unit by an extrusion member provided in the bulk feeder. The electronic circuit components are pushed out of the bulk feeder and mounted on the circuit board.

In this way, if the bulk feeder is moved relative to the circuit board and the electronic circuit components supplied by the bulk feeder are mounted on the circuit board, the bulk feeder is fixed and the suction nozzle is in the bulk. The mounting efficiency can be improved as compared with the case where the electronic circuit component is received and mounted by being moved between the feeder and the circuit board.

However, there is still room for improvement in the conventional electronic circuit component mounting machine. For example, in the electronic circuit component mounting machine described in Patent Document 1, the bulk feeder and the suction nozzle are provided in an invariable relative position, and in the electronic circuit component mounting machine described in Patent Document 2, the electronic circuit component is mounted on the bulk feeder itself. Since the push-out member for mounting the circuit board on the circuit board is provided, any of the electronic circuit components supplied by the bulk feeder can only be mounted on the circuit board, which may be inconvenient. In addition, the suction nozzle described in Patent Document 2 can only mount electronic circuit components received from a tape feeder on a circuit board, which may be unusable.
This problem similarly occurs when electronic circuit components are supplied by a component supply tool other than the bulk feeder, which is moved together with the suction nozzle.
The present invention has been made against the background described above, and an object thereof is to improve the usability of an electronic circuit component mounting machine in which a component supply tool and a suction nozzle are relatively moved together with respect to a circuit board.

A first relative movement device for moving the circuit base material held at a desired position in a plane parallel to the mounting surface ; (E) a second storage portion for storing a plurality of electronic circuit components; and an electronic circuit component. And a second component moving unit that moves electronic circuit components from the second storage unit to the second supply unit, and the mounting machine without using the mounting unit main body. A second component supply tool held by the main body, and a circuit substrate held by the circuit substrate holding portion. The mounting portion of the electronic circuit component mounting machine that mounts the electronic circuit component on the mounting surface by the mounting portion is (a) the mounting portion main body, and (b) is held by the mounting portion main body, and advances and retreats in the axial direction. A suction nozzle having a suction portion at the front end, (c) a first storage portion for storing a plurality of electronic circuit components, a first supply portion for supplying electronic circuit components one by one, and a first thereof A first component moving part for moving an electronic circuit component from the first storage part to the supply part; and a first component supply tool held by the mounting part body; and (d) held by the mounting part body. A second relative movement device that relatively moves the suction nozzle and the first supply portion of the first component supply tool in a direction intersecting the axial direction of the suction nozzle; and (e) held by the mounting portion main body, each other and said first supply unit of the component supply device and the suction nozzle in the component receiving position Approach, first approach, a spacing device to separate the first approach, provided separately from the spacing device, component receiving mounting position from the component-receiving position is a position deviated in a direction crossing the axial direction of the suction nozzle The suction nozzle and the second supply part of the second component supply tool are moved closer to and away from each other, and the suction nozzle and the circuit base material held by the circuit base material holding part are moved closer to and away from each other. It is solved by including two approach and separation devices.

  According to the electronic circuit component mounting machine according to the present invention, the suction nozzle and the supply unit of the component supply tool are moved together with respect to the circuit base material, so that the electronic circuit from the component supply tool to the suction nozzle during the movement is provided. The suction nozzle can receive the electronic circuit component from the component supply device in a state where the component is received or is located at an arbitrary position with respect to the circuit substrate, and the electronic circuit component can be received and attached to the circuit substrate. It can be done efficiently. In addition, since the suction nozzle and the supply part of the component supply tool are relatively moved in the direction intersecting with the axial direction of the suction nozzle, the suction nozzle can be detached from the supply part in the direction intersecting with the axial direction. Thereby, for the suction nozzle, for example, work other than receiving the electronic circuit component from the supply unit of the component supply tool held in the mounting unit main body, for example, the component held in the mounting machine main body without going through the mounting unit main body The electronic circuit component can be taken out from the supply tool by the suction nozzle, and the electronic circuit component held by the suction nozzle can be imaged, so that an electronic circuit component mounting machine with higher mounting efficiency and ease of use can be obtained. In addition, since the suction nozzle and the component supply tool are moved with respect to the stationary circuit base material, the first relative movement is performed as compared with the case where both the suction nozzle and the component supply tool and the circuit base material holding part are moved. The apparatus can be configured simply.

Although it is another 2nd component supply tool as described in the item (3), it includes a storage unit that stores a plurality of electronic circuit components side by side in a plane.
The suction nozzle and the first component supply tool are moved relative to each other in the direction intersecting the axial direction of the suction nozzle, and the positions of the two are shifted. Therefore, not only the first component supply tool but also the second component is moved to the same suction nozzle. Electronic circuit components can also be received from the supply tool and mounted on the circuit substrate. The first component feeder is particularly effective when it is necessary to mount a large number of the same electronic circuit components on one circuit substrate, and the second component feeder is depending on the first component feeder. Used to supply electronic circuit components that cannot be supplied. This is particularly useful when the electronic circuit component cannot be supplied by the first component supply tool due to its shape, dimensions, electrical characteristics, and the like.
When the mounting portion has one suction nozzle, the suction nozzle selectively receives electronic circuit components from the first and second component supply tools. This selection may be performed for one circuit substrate or different circuit substrates. In the latter case, the mounting unit receives the electronic circuit component from the first component supply tool and mounts it on the circuit substrate, and the mounting unit receives the electronic circuit component from the second component supply tool and mounts it on the circuit substrate. Can be thought of as being integrated.
When the mounting portion has a plurality of suction nozzles, the electronic component may be supplied to the second component supply tool together with the first component supply device with respect to one circuit substrate. The electronic circuit component may be supplied to only one of the tools. In the former case, for example, some of the plurality of suction nozzles may receive electronic circuit components from the first component supply unit, and the remaining suction nozzles may receive electronic circuit components from the second component supply tool. The suction nozzle may alternately receive the electronic circuit components from the first and second component supply tools. When the electronic circuit component is supplied to only one of the first and second component supply tools with respect to one circuit base material, the mounting portion is integrally provided with the two mounting portions as described above.

In the electronic circuit component mounting machine described in Japanese Patent Laid-Open No. 2006-120676, the electronic circuit component supplied by the bulk feeder is mounted on the circuit board by the extrusion member provided in the bulk feeder. Of course, it cannot be used for mounting the electronic circuit components supplied by the tape feeder to the circuit board, and the suction nozzle provided on the rotating body together with the bulk feeder is also supplied by the tape feeder.

Therefore, when an electronic circuit component supplied by only one of the bulk feeder and the tape feeder is mounted on the circuit board, a member for mounting the electronic circuit component supplied by the other on the circuit board cannot be used. Since only a part of the plurality of mounting functions of the mounting machine can be used, the usability is poor and the mounting efficiency is lowered. On the other hand, according to the electronic circuit component mounting machine described in this section, since the suction nozzle is not limited to the component supply tool that receives the electronic circuit component, the electronic circuit component is supplied by either the first or second component supply tool. There is no suction nozzle that cannot be used even in the case where the electronic circuit components are mounted efficiently. The mounting of the electronic circuit component on the circuit substrate is achieved by the provision of the second component supply tool and the fact that the suction nozzle can receive the electronic circuit component from any of the first and second component supply tools.

In addition, the supplyable amount detection device detects the supplyable amount by detecting the height of the upper surface of the layer of the electronic circuit component housed in a separate state in the housing portion, or in the housing portion. It is also possible to detect the suppliable amount by detecting the weight of the electronic circuit components housed separately. In the former case, it is better to detect the height of the upper surface of the layer of the electronic circuit component while the larger the horizontal cross-sectional area in the upper portion of the storage portion, the better the outflow of the electronic circuit components from the storage portion. Therefore, it is desirable to detect the height of the upper surface of the layer of the electronic circuit component at a portion where the horizontal cross-sectional area of the storage portion is small. It is desirable that the electronic circuit components are introduced relatively frequently. For example, a part of the target supply amount determined by the method described in the item (22) is set as the target supply amount. A plurality of devices for detecting the height of the upper surface of the electronic circuit component layer may be provided at different positions in the height direction. For example, the height detection device is provided at each of the position where the target supply amount is detected as the supplyable amount and the position where the set lower limit amount described in the item (20) is detected as the supplyable amount.
The function of the loading end notifying unit varies depending on whether or not the electronic circuit component mounting machine includes an automatic loading / unloading unit as described in the above item (18).
In addition, in the aspect described in the item (18), the electronic circuit component is loaded from the component loading device held in the mounting machine main body to the storage unit of the bulk feeder held in the mounting portion main body. When the process is started in a state where no parts are held, the target supply amount in the item (21) is the same as the target input amount in the item (18). Therefore, in this case, the “target supply amount” can be read as “target input amount” and the following items (22) and (23) can be subordinate to the item (18). The same applies to the target input amount described in item (19).
According to the electronic circuit component mounting machine of this section, the effect of supplying the electronic circuit components by the bulk feeder can be obtained, and the amount of electronic circuit components according to the purpose can be supplied to the bulk feeder by setting the target supply amount.

Therefore, in a mode in which this item is subordinate to the item (22), the target supply amount is set according to which of the lowering of performance due to blackening or the lowering of efficiency due to interruption of wearing is prioritized.
(24) When the target supply amount determined by the target supply amount setting unit is equal to or greater than the upper limit supplyable amount of the electronic circuit component of the storage unit, the supplyable amount detected by the supplyable amount detection device is The electronic circuit component mounting machine according to (22) or (23), wherein when the upper limit supplyable amount is reached, at least one of the charging end notification unit and the automatic charging stop unit is activated.
When the target supply amount is smaller than the upper limit supplyable amount, the electronic circuit components are not input to the storage unit up to the upper limit supplyable amount, and a set amount of electronic circuit components is input. On the other hand, if the target supply amount is equal to or greater than the upper limit supplyable amount, the electronic circuit component is put into the storage unit up to the upper limit.

This is because, if the storage portion can be removed, the operator can remove it and discharge the electronic circuit components. In this case, an outflow prevention means for preventing the electronic circuit component from flowing out of the removed storage portion, for example, an opening / closing member for opening / closing the component outflow side opening of the storage portion, or a part forming the component outflow side opening is provided. It is desirable to prepare a magnet for bringing the electronic circuit components in the component outflow side opening close to each other and preventing them from flowing out. If the magnet is an electromagnet, it is easy to switch between the magnetized state and the demagnetized state, and the outflow allowable state and the outflow prevention state can be easily realized. The opening / closing member may be a member that is manually moved to an open position and a closed position by an operator, and a member that is automatically moved to an open position and a closed position by an opening / closing member moving device having a drive source. May be. Note that the entire bulk feeder including the storage unit, the supply unit, and the component moving unit may be removable from the mounting unit main body.
Forcible discharge is performed, for example, at the end of mounting the electronic circuit component on the circuit base material, at the time of changing the type of the circuit base material, at the time of maintenance, or the like. By forcibly discharging at the time of changing the type of the circuit substrate, at least the storage portion can be used for supplying a plurality of types of electronic circuit components, and the apparatus cost can be reduced.

The mounting of the electronic circuit component on the circuit board 40 by the mounting head 132 will be described.
The mounting head 132 is mounted on the second X-axis slide 148 in at least one of the plurality of mounting modules 10 constituting the electronic circuit component mounting line, and is used for mounting the electronic circuit components. Here, the mounting head 132 has all the 12 nozzle holders 170 holding the same kind of suction nozzles 172, takes out electronic circuit components from the bulk feeder 402 and the tape feeder 50, and mounts them on the circuit board 40. To do. There are more types of electronic circuit components to be mounted on the circuit board 40 than the number of bulk feeders 402, and insufficient types of electronic circuit components are supplied by the tape feeder 50. In addition, 24 electronic circuit components are mounted on the circuit board 24, 21 of which are bulk components 472, and 3 are electronic circuit components supplied by the tape feeder 50 (hereinafter referred to as tape feeder supply components in some cases). The mounting head 132 is mounted on one circuit board 40 by two rotations of the rotating body 180 (hereinafter, mounting by one rotation of the rotating body 180 is referred to as one cycle), and 12 mounting heads are mounted in the first cycle mounting. The bulk parts 472 are mounted, and in the second cycle mounting, nine bulk parts 472 and three tape feeder supply parts are mounted.

  The circuit board 40 is carried into the mounting module 10 by the board transfer device 20 and is held by the board holding device 22. When holding the circuit board 40 and releasing the holding, the board holding device 22 moves its support member and clamp member, but does not move after holding, and during the mounting work of the electronic circuit component Stay stationary. The reference mark of the circuit board 40 held by the board holding device 22 is imaged by the reference mark imaging device 28, and each position error of a plurality of component mounting locations is calculated. This position error includes each position error in the X-axis and Y-axis directions and a rotational position error that is a position error about an axis perpendicular to the mounting surface of the circuit board 40.

  First, the twelve suction nozzles 172 of the mounting head 132 are sequentially swung to the component receiving position by the rotation of the rotating body 180 and take out the component 472 from the bulk feeder 402. At the time of mounting the electronic circuit component, the type of the electronic circuit component, the component supply device designating data, the data designating the component feeder that supplies the electronic circuit component, and the data such as the component mounting location are read from the mounting program in the order of mounting. Data read from the mounting program is sent from the module control computer 120 to the mounting head control computer 372, and the feeder moving device 420 based on the head body holding component supply device designation data and the bulk feeder designation data included in the data. A controlled and designated bulk feeder 402 is positioned at the component supply position to supply a set type of bulk component 472. Further, the lifting device 262 and the valve switching device 300 are operated based on the head body holding component supply device designation data, and the suction nozzle 172 receives the bulk component 472 at the component receiving position.

  The nozzle holder 170 is lowered by the elevating device 262 at the component receiving position, and the valve spool 202 of the switching valve device 200 provided corresponding to the nozzle holder 170 is pushed down by the valve switching device 300 so that the positive pressure supply position is reached. To the negative pressure supply position, and negative pressure is supplied to the suction nozzle 172 to suck the bulk component 472. The drive member 270 of the elevating device 262 is lowered in a state where the downstream end of the engagement protrusion 222 of the engagement member 210 of the nozzle holder 170 reaches the lower side of the roller 290 of the drive member 270. Then, the nozzle holder 170 is pushed down. The nozzle holder 170 is swung and lowered in parallel, and this parallel movement is allowed by the rotation of the roller 290.

  In the bulk feeder 402, the stopper 644 is positioned at the stop position, and the leading component 472 abuts against the stopper 644 in the guide passage 500, is positioned at the component extraction position, and is positioned below the component extraction port 628. Yes. The suction nozzle 172 is lowered to suck the part 472 and then lifted, and the part 472 is taken out from the guide passage 500 through the part take-out port 628. After removal, compressed air is ejected from the air ejection passage 630 to the guide passage 500, and the component 472 is moved to the supply section. A plurality of holes 652 are formed in the stopper 644, and air passes through the holes 652 and exits the stopper 644, whereby an air flow is obtained. The leading part 472 is brought into contact with the stopper 644 and stopped, and is put on standby for removal.

  Here, the component discharge promoting device 416 is operated each time a preset number of components 472 are supplied. At the time of operation, the discharge promoting cylinder 510 is raised from the lowered end position to the raised end position in parallel with the lowering of the suction nozzle 172, and enters the bulk part 472 in the case 412. Thereby, the bridge between the bulk parts 472 is eliminated, and the guide surface 518 is positioned above the discharge hole 498 to guide the entry of the bulk part 472 into the pipe 520. The discharge promotion cylinder 510 is lowered to the lower end position in parallel with the feeding of the component 472.

  The suction nozzle 172 that has received the bulk component 472 at the component receiving position is moved to the component imaging position by the rotation of the rotating body 180, the bulk imaging component 472 is imaged by the component imaging device 240, the imaging data is subjected to image processing, and the suction nozzle. The holding position error of the bulk component 472 due to 172 is calculated. The holding position error includes a position error in the X-axis and Y-axis directions and a rotational position error that is a position error around the axis. After the imaging, the suction nozzle 172 that reaches the component mounting position by the rotation of the rotating body 180 is lowered by the lifting device 260 to mount the bulk component 472 on the component mounting portion of the circuit board 40. Since the bulk feeder 402 is mounted on the head main body 186, the mounting head 132 is moved in parallel with the reception of the bulk component 472 from the bulk feeder 402 by the suction nozzle 172 and the imaging of the bulk component 472 held by the suction nozzle 172. The head moving device 134 can be moved with respect to the substrate holding device 22, the suction nozzle 172 can be positioned on the component mounting position, and the held bulk component 472 can be mounted on the circuit board 40.

  At this time, by correcting the movement position of the mounting head 132, the positional deviations in the X-axis and Y-axis directions of the parts mounting positions of the bulk component 472 and the circuit board 40 held by the suction nozzle 172 are corrected. Further, the nozzle holder 170 is rotated around its own axis by the nozzle holder rotation driving device 350, and the rotational position errors of the bulk component 472 and the component mounting position held by the suction nozzle 172 are corrected. At the same time, the holding direction of the electronic circuit component is also changed. Since the nozzle holder rotation driving device 350 rotates the 12 nozzle holders 170 simultaneously, the rotation of the nozzle holder 170 is performed in consideration of the rotation angle of the other nozzle holders 170. The same applies to the case where the rotational position error of the bulk component 472 is acquired based on imaging. Control for simultaneous rotation of all the nozzle holders 170 is known, for example, from Japanese Patent Laid-Open No. 10-163677, and the description thereof is omitted.

  Even when the bulk part 472 is mounted, the turning and lowering of the nozzle holder 170 are performed in parallel. Further, the valve switching device 302 raises the valve spool 202 located at the negative pressure supply position to the positive pressure supply position, and the supply of the negative pressure to the suction nozzle 172 is shut off and the positive pressure is supplied.

  The bulk feeder 402 and the component imaging device 240 are provided in the head body 186 together with the suction nozzle 172 and are moved together with respect to the substrate holding device 22, and the twelve suction nozzles 172 are rotated by the rotation of the rotating body 180. It is moved with respect to the bulk feeder 402 and the component imaging device 240. Therefore, regardless of the position of the mounting head 132, the suction nozzle 172 that has reached the component receiving position can receive the bulk component 472 from the bulk feeder 402, and the electronic circuit components that are held by the suction nozzle 172 that has reached the component imaging device. The component imaging device 240 can take an image, the bulk component 472 is taken out from the bulk feeder 402 by one of the plurality of suction nozzles 172, and the bulk component 472 held by another one is imaged by the component imaging device 240. In addition, the bulk component 472 held by another one can be mounted on the circuit board 40 in parallel.

  By this parallel operation, the 12 bulk components 472 in the first cycle are mounted on the circuit board 40. Furthermore, here, following the mounting of the 12 bulk components 472 in the first cycle, the mounting of the 9 bulk components 472 in the second cycle to the circuit board 40 is performed, and the mounting of the bulk components 472 in the first cycle. In addition, reception and imaging of the bulk component 472 in the second cycle from the bulk feeder 402 are performed in parallel. Nine suction nozzles 172 receive the bulk component 472 and attach it to the circuit board 40.

  In the second cycle, since three tape feeder supply components are mounted on the circuit board 40, after the nine bulk components 472 in the second cycle have been mounted, the mounting head 132 is one of the 12 suction nozzles 172. Also, the electronic circuit component is moved to the component supply device 24 without being held. The head moving device 134 is operated based on the module body holding component supply device designation data and the tape feeder designation data included in the data read from the mounting program, and the mounting head 132 is moved to the designated tape feeder 50. From the tape feeder 50, the suction nozzle 172 actually located at the component receiving and mounting position and the two suction nozzles 172 adjacent to the suction nozzle 172 upstream in the rotation direction of the rotating body 180 are transferred to the total three suction nozzles 172. Receive circuit components. At this time, the lifting device 260 and the valve switching device 302 are operated based on the module main body holding component supply device designation data, and the suction feeder 172 receives the tape feeder supply component at the component receiving and mounting position. The component supply device designation data is also component reception stop position designation data that designates at which of the 12 stop positions the suction nozzle 172 receives electronic circuit components, and includes the lifting devices 260 and 262 and the valves. It is also data that designates which of the switching devices 300 and 302 is to be operated.

  After receiving the parts, the first suction nozzle 172 that rotates the rotating body 180 at a time to hold the tape feeder supply parts, that is, the suction nozzle 172 located on the most downstream side in the rotation direction of the rotating body 180 captures the parts. It is moved to a position and the tape feeder supply component is imaged. Thereafter, the tape feeder supply components held by the remaining two suction nozzles 172 are imaged by intermittent rotation of the rotary body 180, and then the rotary body 180 is rotated 120 degrees at a time, so that the leading suction nozzle 172 is rotated. Is moved to the component receiving and mounting position, and the tape feeder supply component is mounted on the circuit board 40. Thereafter, the remaining two suction nozzles 172 are moved to the component receiving and mounting position by intermittent rotation of the rotating body 180, and the held tape feeder supply component is mounted on the circuit board 40.

  Every time all the electronic circuit components scheduled for one circuit board 40 are mounted, all the suction nozzles 172 do not hold the electronic circuit components, and the mounting head 132 is emptied. Next, electronic circuit components are mounted on the circuit board 40 to be carried in. The mounting head 132 causes the suction nozzle 172 to receive the bulk component 472 from the bulk feeder 402 when the circuit board 40 is loaded into the mounting module 10 or when the reference mark imaging device 28 images the reference mark. Then, the component imaging device 240 can image the bulk component 472 to prepare for mounting on the circuit board 40. In parallel with the mounting of the tape feeder supply component on the circuit board 40 in the second cycle of the mounting head 132, the suction nozzle 172 can receive the bulk component 472 of the first cycle mounted on the next circuit board 40. It is.

  In the mounting module 10, the mounting head 132 is not empty in which the bulk part 472 is not accommodated in the case 412, the bulk part 472 is not held in the entire pipe feeder 402, and the bulk part 472 is not held at all in the bulk feeder 402. In this state, the bulk component 472 is loaded into the case 412 by the component loading device 700 prior to the start of mounting of the bulk component 472 on the circuit board 40. The loading of the bulk component 472 into the case 412 by the component loading apparatus 700 is also performed during the mounting of the bulk component 472 on the circuit board 40 as necessary.

  First, an initial input number setting routine shown in FIG. 33 is executed in the module control computer 120, and an initial input number that is the number of bulk parts 472 to be input to the empty case 412 is set for each of the two bulk feeders 402. . The initial number of inputs is a target number of inputs that is a target input amount.

  In step 1 (hereinafter abbreviated as S1. The same applies to other steps), the number of circuit boards 40 to be produced, that is, the number of circuit boards 40 on which electronic circuit components are scheduled to be mounted by the mounting module 10. Is read from the production program. Next, in S2, the number of bulk parts 472 to be supplied from each of the two bulk feeders 402 for the production of one circuit board 40 is read from the production program. Then, S3 is executed, and the product of the planned production number of circuit boards 40 read in S1 and S2 and the number of supplied parts of one bulk feeder 402 is calculated, and the number obtained by this is obtained by the suction nozzle 172. The total number of bulk parts 472 supplied from one bulk feeder 402 for the production of a predetermined number of circuit boards 40 is the number that is added to the number required for recovery of suction mistakes or mounting mistakes of the bulk parts 472. (Hereinafter referred to as the total number of supplied bulk parts).

  Next, in S <b> 4, for one of the two bulk feeders 402, it is determined whether or not the total production time is longer than the blackening limit time of the bulk part 472 supplied by the bulk feeder 402. The total production time is the total time required to mount 21 bulk parts 472 and 3 tape feeder supply parts on the circuit board 40 of the planned production number by the operation of the mounting head 132 in the two cycles. For one circuit board 40, the production time is calculated based on the moving distance and moving speed of the mounting head 132 for imaging the reference mark, receiving the component, mounting the component, and the like. Calculated by multiplying. Here, for simplification, blackening of the bulk component 472 due to the operation of promoting the discharge of the bulk component 472 from the case 412 to the pipe 520 by the component discharge promoting device 416 is ignored. The total production time may be calculated in consideration of conversion.

  Blackening occurs when the bulk component 472 rubs in the case 412 when the mounting head 132 is moved, and as the moving time increases, the blackening proceeds and eventually becomes unusable as an electronic circuit component. The blackening limit time is as long as possible within a range in which it is ensured that blackening does not progress so much that the bulk part 472 cannot be used, and is obtained by an experiment in advance for each type of the bulk part 472, It is stored in a blackening time memory provided in the RAM of the module control computer 120 in association with the type of the bulk component 472. The blackening time memory constitutes a storage means. The same applies to other memories.

  If the total production time is longer than the blackening limit time, S8 is executed, the maximum number of parts supplied in a range not exceeding the blackening limit is set to the initial charging number, and the bulk part 472 is loaded into one bulk feeder 402 Is output to the control computer 822 of the component input device 700. The bulk feeder 402 and the component input device 700 are associated with each other according to the type of the bulk component 472 supplied by the bulk feeder 402. The maximum number of parts supplied in a range not exceeding the blackening limit is calculated, for example, by calculating the number of circuit boards 40 that can be produced within the blackening limit time and mounting the number of circuit boards 40 on one circuit board 40. It is calculated by multiplying the number of bulk parts 472 supplied by one bulk feeder 402. Here, this maximum component supply number is the target supply number that is the target supply amount.

  Next, S9 is executed, and it is determined whether or not the maximum component supply number calculated in S8 is equal to or greater than the upper limit supplyable number that is the upper limit supplyable amount of the case 412. The upper limit supplyable number is the maximum number of bulk parts 472 that can be properly accommodated in the case 412 (for example, with an appropriate space remaining in the upper part), and is preset for each type of bulk part 472. Are stored in an upper limit supplyable number memory provided in the RAM of the module control computer 120.

  If the maximum component supply number is less than the upper limit supplyable number, S9 is NO and S10 is executed, the maximum component supply number is set to the initial input number, and the bulk component 472 is input to one bulk feeder 402. The data is output to the component input device control computer 822. In S10, the maximum component supply number, which is the initial input number, can be supplied in the RAM of the module control computer 120 as the initial value of the supplyable number, which is the amount of the bulk component 472 that can be supplied from the bulk feeder 402. It is stored in the numerical initial value memory in association with the bulk feeder specifying data. The initial input number is the number of bulk parts 472 initially accommodated in the case 412, and subtraction should be started every time one bulk part 472 is supplied in order to determine the following additional input execution time. Is a number. In addition, when the determination result of S4 is YES and the initial charging number is set, the initial charging number is smaller than the total bulk component supply number. This is because the number of bulk parts 472 supplied in a time shorter than the total production time and shorter than the black production limit time is smaller than the total number of bulk parts supplied. Therefore, it is necessary to supply or add the bulk component 472 to the bulk feeder 402 during the mounting of the bulk component 472 to the predetermined number of circuit boards 40, and this is associated with the bulk feeder specifying data and module control is performed. It is stored in a replenishment necessity memory provided in the RAM of the computer 120.

  If the maximum component supply number is equal to or greater than the upper limit supplyable number of case 412, S9 becomes YES, S11 is executed, and the upper limit supplyable number of case 412 is set to the initial input number. Then, an output of the initial input number to the component input device control computer 822, storage of component supply necessity, and setting of the upper limit supplyable number which is the initial input number to the initial value of the component supplyable number are performed. In this case, it can be considered that the target supply number is equal to or greater than the upper limit supplyable number, and the upper limit supplyable number is the target supply number.

  On the other hand, if the total production time is equal to or less than the blackening limit time, S5 is executed, and it is determined whether or not the total supply number of bulk parts is equal to or less than the upper limit supplyable number of the case 412. If the total number of supply of bulk parts is less than or equal to the upper limit supplyable number of cases 412, S6 is executed, and the total number of supply of bulk parts calculated in S3 for one bulk feeder 402 is set as the initial input number, and the part input device control is performed. The data is output to the computer 822. In this case, it is not necessary to supply the bulk component 472, and that effect is stored in the supply necessity memory in association with the bulk feeder specifying data. The initial value of the supplyable number is not set. Here, the total supply number of bulk parts is the target supply number.

  If the total production time is equal to or less than the blackening limit time, but the total number of bulk parts supplied is greater than the upper limit supplyable number of the case 412, S5 becomes NO and S7 is executed in the same manner as S11. Even if the total production time is short, the upper limit supplyable number of cases 412 may be exceeded depending on the number of mounted bulk components 472 per circuit board.

  After execution of any of S6, S7, S10, and S11, S12 is executed, and it is determined whether or not the initial charging number has been set for all the bulk feeders 402. Here, since the initial input number has only been set for one of the two bulk feeders 402, S12 becomes NO, and S4 to S11 are executed for the other bulk feeder 402.

  If the initial charging number is set for the two bulk feeders 402, S13 is executed, and one of the two bulk feeders 402 set in advance by the movement of the mounting head 132 is placed in the case 412 of the bulk feeder 402. The bulk component 472 is moved to the component loading device 700 for loading. The mounting head 132 is moved in the Y-axis direction after the position of the bulk feeder 402 in the X-axis direction coincides with that of the component input device 700 and then moved closer to the component input device 700.

  Accordingly, as shown in FIG. 36A, the shutter 480 of the case 412 is moved closer to the driving member 812 of the component loading device 700, and the driving member 812 is inserted into the groove 482 as shown in FIG. Mated. A rail 820 is fitted into the guide groove 484 to guide the movement of the case 412 relative to the drive member 812. After the shutter 480 comes into contact with the drive member 812, the shutter 480 is retracted against the urging force of the spring 494, and the opening 476 is opened. The mounting head 132 is a position set in advance with respect to the component input device 700. As shown in FIG. 36B, the shutter 480 is moved to the open position, and the entire opening 476 is opened, so that the drive member 812 is opened. The component discharge port 814 is opposed to and communicated with the component discharge port 814 and moved to a position where a component input state can be obtained. This position is the component insertion position, and the component discharge port 814 is positioned inside the opening 476 in plan view. After the movement, a signal indicating the movement completion is output from the module control computer 120 to the component input device control computer 822.

  In the component loading apparatus 700, the component loading routine shown in FIG. 34 is executed, and the bulk component 472 is loaded into the case 412. First, in S21, it is determined whether or not the movement of the bulk feeder 402 is completed, that is, whether or not the mounting head 132 has been moved to a preset component loading position and the opening 476 of the case 412 has been opened. If the movement completion signal is output from the module control device 32, S21 becomes YES, the electric motor 754 is activated in S22, and the component conveying belt 750 is rotated.

  As a result, the leading component receiving recess 804 in which the bulk component 472 is stored, the component receiving recess 804 reaching the tip of the horizontal portion 772 is directed downward, and the bulk component 472 falls apart and falls into the side wall portion. Between the lower end portions 811 and 813 of 796 and 798, it is dropped into the case 412 through the component discharge port 814 and the opening 476. The entry of the bulk component 472 from the component receiving recess 804 into the component discharge port 814 is guided by the inclined surfaces 815, 816, 817 and 818. Further, as the component conveying belt 750 moves, the empty component receiving recesses 804 sequentially reach a position facing the discharge port 734 of the case 720, and the bulk component 472 in the case 720 is discharged as shown in FIG. It enters the component receiving recess 804 through the outlet 734.

  In S23, it is determined whether or not the actual input number that is the actual input amount of the bulk part 472 into the case 412 has reached the target input number, here the initial input number. The determination in S23 is made based on whether or not the rotation angle of the electric motor 754 that rotates the component conveying belt 750 is equal to or larger than the set rotation angle. The average value of the bulk components 472 accommodated in one component accommodating recess 804 is acquired in advance, and the number of component accommodating recesses 804 that allow components to be introduced into the case 412 can be obtained from the number and the target number. Then, the feed amount of the component conveying belt 750 necessary for putting the bulk component 472 into the set number of component receiving recesses 804 is set, and the rotation angle of the electric motor 754 is set and used for the determination of S23. The set rotation angle is set by the component input device control computer 822. From the rotation angle of the electric motor 754, the number of component receiving recesses 804 into which the bulk component 472 has been input is obtained, and the actual input number is calculated by multiplying the number of component storage in one component receiving recess 804, and compared with the target input number. May be.

  S23 is repeatedly executed until the rotation angle of the electric motor 754 becomes equal to or larger than the set rotation angle and the actual number of inputs reaches the target number of inputs. If the actual number of inputs reaches the target number of inputs, S24 is executed and the electric motor 754 is stopped. After stopping, the electric motor 754 is rotated in the reverse direction, and the component conveying belt 750 is returned by the set distance. The set distance is a distance that guarantees that the leading component-accommodating recess 804 in which the bulk component 472 is accommodated is in a horizontal and upward state. The first part accommodating recess 804 does not necessarily contain all of the predetermined number of bulk parts 472, and may be supplied with a part dropped.

  By returning the component conveying belt 750, at the end of loading, the component conveying belt 750 is stopped in a state where the leading component accommodating recess 804 in which the bulk component 472 is accommodated is inclined, and the bulk component 472 is placed in the component accommodating recess 804. Even if it remains, the component receiving recess 804 is in a horizontal and upward state, and it is guaranteed that the bulk component 472 does not fall from the component receiving recess 804. For this reason, at the start of component loading, the component transport belt 750 is first fed forward by a distance equal to the return distance, and then fed until the rotation angle of the electric motor 754 becomes equal to or greater than the set rotation angle. The bulk component 472 is excessively charged into the case 412 as much as it remains in the component accommodating recess 804, but there is little trouble as compared with the entire input amount. After the component conveying belt 750 is returned, a signal indicating the end of loading of the bulk component 472 is output to the module control computer 120.

  During the parts insertion, S14 is repeatedly executed in the initial number setting routine. If a component loading end signal is output from the component loading device control computer 822, the determination in S14 is YES, S15 is executed, and it is determined whether or not the components are loaded for the two bulk feeders 402. Here, since the parts have not yet been input for the two bulk feeders 402, the determination in S15 is NO, and S13 and S14 are executed for the other bulk feeder 402. First, the mounting head 132 is moved in a direction in which one bulk feeder 402 is separated from the component input device 700 in the Y-axis direction. As a result, the mounting head 132 allows the driving member 812 to be removed from the groove 482, the opening 476 is moved to a separated position separated from the component discharge port 814, and the shutter 480 is moved by the biasing force of the spring 494. 476 is closed, and a shut-off state in which communication with the component discharge port 814 is shut off is obtained. The mounting head 132 is moved in the Y-axis direction until the entire case 412 is disengaged from the extending portion 810 of the component loading device 700, and then the other bulk feeder 402 puts the bulk component 472 into the case 412 of the bulk feeder 402. It is moved to the component input device 700 to be input.

  The positioning of the other bulk feeder 402 with respect to the component input device 700, the opening and closing of the shutter 480, and the input of the components are performed in the same manner as the bulk feeder 402, and when the input is completed, a component input end signal is sent to the component input device control computer 822. To the module control computer 120. As a result, the determination in S14 is YES, the determination in S15 is also YES, S16 is executed, and the end of loading is displayed on the display screen 834 and notified. When the upper limit supplyable number of bulk parts 472 are put in the case 412, when the supplyable number reaches the upper limit, a notification is made. In addition, the mounting head 132 is moved to the substrate holding device 22, and mounting of the bulk component 472 on the circuit board 40 is started. The end of loading may be notified every time when the loading of components for one bulk feeder 402 is completed.

  When the bulk component 472 is mounted on the circuit board 40, the module control computer 120 executes an additional input number setting routine shown in FIG. This routine is executed separately for each of the two bulk feeders 402. Hereinafter, the setting of the number of additional inputs for one bulk feeder 402 will be described.

  First, in S31, it is determined whether or not parts need to be replenished. This determination is made based on whether or not replenishment is required when the initial number of bulk parts 472 to be set for the bulk feeder 402 is set. If the initial input number is set to the total number of supply of bulk parts, since the bulk parts 472 necessary for mounting on the circuit board 40 of the predetermined number are held in the bulk feeder 402, replenishment is unnecessary, The determination in S31 is NO, and the execution of the routine ends.

  If the initial number of inputs is less than the total number of supplied bulk parts and parts need to be replenished, S32 is executed, and it is determined whether or not the bulk parts 472 have been taken out from the bulk feeder 402 by the suction nozzle 172. If the bulk parts 472 are taken out from the bulk feeder 402 in which the additional input number setting routine is executed, S33 is executed, and the supply is possible, which is the number of bulk parts 472 that the bulk feeder 402 can supply. The number is subtracted by one. The initial value of the supplyable number is set to the initial input number in any of S7, S10, and S11.

  And S34 is performed and it is determined whether the supply possible number is below a setting minimum number. Although the bulk component 472 still remains in the bulk feeder 402, for example, if the supply continues, for example, the bulk component 472 may be lost during the reception of the bulk component 472 by the plurality of suction nozzles 172 of the mounting head 132. If the suction error or the mounting error is recovered, the number is set such that the bulk component 472 may be insufficient. When the supplyable number is larger than the set lower limit number, S34 is NO and the execution of the routine ends.

  If the supplyable number is equal to or less than the set lower limit number, S35 is executed, and it is determined whether or not the number of unmounted parts is larger than the initial number of input parts. The number of unmounted parts is the number of bulk parts 472 that are not yet mounted among the bulk parts 472 that should be supplied from the bulk feeder 402 for the circuit board 40 that is to be produced, and has already been mounted from the total number of supplied bulk parts. This is obtained by subtracting the number of bulk parts 472. The number of mounted components is the number of circuit boards 40 that have been mounted, the number of bulk components 472 that are mounted per sheet, and if the number of mounted components is in the process of being mounted on one circuit board 40 Obtained by the number of bulk parts 472 produced.

  If the number of unmounted parts is greater than the initial number of parts, S36 is executed, and the number obtained by subtracting the set lower limit number from the initial number of parts is set as the number of parts to be additionally supplied to the bulk feeder 402 by the parts input device 700. And output to the component input device control computer 822. Then, by executing S37, the mounting head 132 is moved to the component input device 700, and the bulk component 472 is input by the component input device 700. In the component loading apparatus 700, a component loading routine is executed, and the bulk component 472 is loaded in the same manner as in the initial loading with the additional number of throws as the target number of throws. However, the set rotation angle of the electric motor 754 is set based on the number of additional inputs. When the component insertion is completed, the determination in S38 is YES based on the output of the component insertion end signal, S39 is executed, the completion of insertion is notified, and the mounting head 132 is moved to the substrate holding device 22, The mounting of the bulk component 472 on the circuit board 40 is resumed.

  If the number of unmounted parts is equal to or less than the initial number of input parts, S40 is executed, and the number obtained by subtracting the set lower limit number from the number of unmounted parts is set as the additional input number and output to the part input device control computer 822. The apparatus 700 causes the bulk part 472 to be additionally charged. In this case, since it is not necessary to supply the bulk part 472 further, it is stored in the replenishment necessity memory instead of parts replenishment necessity. Therefore, the next time S31 is executed, the determination is NO, and S32 to S40 are skipped.

The forced discharge of parts from the bulk feeder 402 will be described.
In this embodiment, forced discharge is performed for the case 412 and the feed passage 500, and the entire bulk feeder 402 is emptied. Forcible discharge is performed, for example, when the type of component supplied by the bulk feeder 402 changes or when mounting of an electronic circuit component on the circuit board using the mounting head 132 in the mounting module 10 is completed. At this time, first, the mounting head 132 is moved to a part discharge work position set in advance in the movement region, for example, the frontmost side of the mounting module 10 in the front-rear direction and the center position in the left-right direction. Is stopped.

  Then, the operator removes the case 412 from the feeder main body 410. In this case, first, as shown in FIG. 37, the discharge promotion cylinder 510 is raised by the discharge promotion cylinder drive device 512 to the case removal position where its upper end surface is located in the same plane as the upper end surface of the pipe 510 and the discharge hole 498. Be made. In this state, the operator holds the operation portion 610, applies a forward force to the operation rod 590, causes the ball 620 of the ball plunger 618 to come out of the recess 622, and disengages from the operation rod 590. Thereby, the operating rod 590 is advanced by the urging force of the spring 614, the shutter 580 is moved to the closed position, and the lower opening 517 of the space 470 is closed as shown in FIG. At this time, the shutter 580 is moved forward between the upper end surface of the discharge promoting cylinder 510 and the pipe 520 and the bulk component 472 mounted on the upper end surface of the shutter 580 and scooped up.

  After the opening 517 is closed by the shutter 580, the operator lifts the case 412 upward, causes the ball 450 of the ball plunger 446 to come out of the recess 460, and removes the case 412 from the feeder body 410, as shown in FIG. The operator takes the removed case 412 to a component container (not shown) provided outside the mounting module 10, turns the case 412 upside down, opens the shutter 480, and accommodates the bulk component 472 in the component container. The case 412 is emptied. The operator fits the concave portion 444 of the empty case 412 to the attachment portion 454 and attaches it to the feeder main body 410, moves the shutter 580 to the open position, and opens the opening 517. An electronic circuit component is input to the empty case 412 by the component input device 700.

  The bulk part 472 remaining in the pipe 520 and the guide passage 500 is sent forward by the part moving device 414 and received by the part receiver 646. At this time, the stopper 644 is moved to the release position to release the guide passage 500, and the component receiver 646 is positioned to the accommodation position. Therefore, when air is ejected from the air ejection passage 630 and the bulk component 472 is moved forward in the guide passage 500 by the flow of air, the bulk component 472 jumps out of the guide passage 500 and is received by the component receiver 646. At this time, the bulk component 472 strikes against the cushioning material 654, the impact of the collision with the component receiver 646 is reduced, the damage is avoided, and the bulk component 472 falls and is accommodated in the component receiver 646.

  After discharging all the bulk parts 472, the operator removes the part receiver 646 from the feeder body 410 and collects the stored bulk parts 472. The operator moves the component receiver 646 upward or downward along the dovetail groove 670 to remove it from the feeder book 410, and accommodates the accommodated bulk component 472 in the component container. After the bulk component 472 is collected, the rail 664 is fitted into the dovetail groove 670 and the component receiver 646 is attached to the feeder main body 410 in the non-accommodating position, and the stopper 644 is positioned at the stop position.

  When the bulk component 472 is forcibly discharged when the mounting head 132 is used, the mounting head 132 may be removed from the second X-axis slide 148. The forcible discharge of the bulk part 472 in the guide passage 500 and the pipe 520 is performed in a state where the mounting head 132 is attached to the second X-axis slide 148, and the forcible discharge of the bulk part 472 in the case 412 is performed by the mounting head 132. It may be performed in a state where it is detached from the 2X-axis slide 148, or both may be performed in a state where the mounting head 132 is attached to the second X-axis slide 148.

As is clear from the above description, in this embodiment, the lifting device 262 constitutes a nozzle holder advancing / retreating device that is a first approaching / separating device, and the lifting device 260 is a second approaching / separating device and a third approaching / separating device. The device is configured, and the third approaching / separating device also serves as the second approaching / separating device. In addition, the shutter 480 and the head moving device 134 constitute a communication / blocking device. The head moving device 134 is also a relative moving device or shutter driving device that moves the bulk feeder 402 and the component loading device 700 relative to each other and moves the shutter 480 between the open position and the closed position. Further, the part moving control unit 134 of the module control device 32 and the part for moving the mounting head 132 between the component loading position and the separation position constitute a component loading control unit. Furthermore, the case 412 is configured to be detachable from the feeder main body 410, the component receiver 646 that is detachably attached to the feeder main body 410, and the component moving device 414 of the module control device 32 to control the pipe 520. Further, the part that sends the bulk part 472 in the guide passage 500 and stores it in the part receiver 646 constitutes a forced discharge means.
Moreover, the part which performs S1-S3 and S6 of the module control computer 120 comprises a 1st target supply amount determination part, and the part which performs S4, S8, and S10 comprises a 2nd target supply amount determination part, Constitutes a target supply amount setting unit. Furthermore, the part of module control computer 120 that executes S6, S7, S10, and S11 constitutes an initial input amount determination unit and an initial holding amount determination unit, and the part that executes S36 and S40 constitutes an additional input amount determination unit. These constitute the target input amount setting unit. The portions of the module control computer 120 that execute S7 and S11 also constitute a storage unit upper limit supplyable amount-dependent initial input amount determination unit and a storage unit upper limit supplyable amount-dependent initial retention amount determination unit, It can also be considered that the possible amount-based target supply amount setting unit is configured.
Further, the part that executes S23 of the component input device control computer 822 constitutes an actual input amount detection device, and the part that executes S24 constitutes an automatic input stop unit. Furthermore, the part that executes S16 and S39 of the module control computer 120 constitutes the charging end notifying unit, the part that executes S33 constitutes the supplyable amount detecting device, and the part that executes S37 constitutes the charging start control unit. doing.
Note that the manner in which S4 and S5 are omitted and S6 is performed is an example of a first target supply amount determination unit that determines the target supply amount regardless of the limit of performance degradation caused by blackening.

  In the above-described embodiment, a simple case has been described for receiving and mounting the bulk component 472 and the tape feeder supply component by the mounting head 132. However, the operation and control of receiving electronic circuit components and the like are not limited thereto. . For example, at least one bulk component 472 and one tape feeder supply component may be alternately received by twelve suction nozzles 172 and mounted on the circuit board 40. In each of a plurality of cycles, Both receiving and mounting with the tape feeder supply component may be performed. Alternatively, only the tape feeder supply component may be received and mounted in one cycle.

  Alternatively, only the bulk component may be mounted on one circuit board, and the mounting head 132 may receive the electronic circuit component only from the bulk feeder 402 that moves together with the suction nozzle 172 and mount it on the circuit board. In some cases, the mounting head 132 can be used to mount only the tape feeder supply component.

  Further, the forced discharge of the parts remaining in the guide passage 500 and the pipe 520 of the bulk feeder 402 causes the suction nozzle 172 to receive the bulk part 472 at the part receiving position, and is downstream from the part receiving position in the rotation direction of the rotating body 180. Alternatively, the bulk component 472 may be released at the component storage position provided at the stop position on the side and stored in the component storage device provided at the component storage position. The component container may be provided in the head main body 186 or the module main body 18. In any case, the component container is detachably provided, and the operator removes and stores the bulk component 472 that is stored.

  In addition, the detection of the actual input amount of the electronic circuit component into the bulk feeder storage unit may be performed by measuring the input time, and the number of electronic circuit components passing through at least one of the component discharge port and the component reception port may be detected. It may be performed by counting. The input time is acquired, for example, by measuring the movement time of the component conveying belt or measuring the passage time of the electronic circuit component at at least one of the component discharge port and the component receiving port.

A shutter may be provided in the component input device, and the component discharge port may be opened and closed. An example thereof will be described with reference to FIGS.
As shown in part in FIG. 40, the component input device 900 of the present embodiment is configured in the same manner as the component input device 700 of the embodiment except that a shutter 902 is provided and the component discharge port 904 is opened and closed. Has been. In the component input device 900, the same reference numerals are given to the components that perform the same operations as the components of the component input device 700, and the description thereof is omitted.

  As shown in FIGS. 40 and 44, the shutter 902 has a rectangular parallelepiped shape and has a width that can be fitted into a groove 482 provided in the ceiling portion 474 of the case 412 of the bulk feeder 402. An opening 910 is formed in the front portion, which is one side portion of the shutter 902 in the longitudinal direction, penetrating in the thickness direction. As shown in FIG. 42, the opening 910 has a rectangular cross-sectional shape, and both the width and the length are smaller than the opening 476 provided in the ceiling portion 474 (see FIG. 45B). ). In addition, rails 912 serving as guided portions are provided in parallel to the longitudinal direction at the other longitudinal ends of both sides of the shutter 902.

  As shown in FIGS. 40 and 43, the extension portion 922 provided at the front end portion of the apparatus main body 920 of the component input device 900 has an accommodating space 923 in which the component conveying belt 750, the guide roller 760, and the like are accommodated. A groove 924 is formed in the lower portion so as to open in the front end surface and the lower surface and extend in the longitudinal direction of the extending portion 922. A partition wall 926 that is a bottom wall of the groove 924 and partitions the groove 924 and the accommodation space 923 is formed with an opening penetrating in the thickness direction or in the vertical direction to constitute a component discharge port 904. The component discharge port 904 has a rectangular cross-sectional shape, and its four side surfaces 928 are inclined surfaces that are inclined toward each other toward the groove 924 from the accommodation space 923 side. The opened portion is smaller than the opening 910 of the shutter 902.

  As shown in FIGS. 40 and 43, both side wall portions parallel to the longitudinal direction of the groove 924 are formed with guide grooves 930 that open to the groove 924 and extend in the longitudinal direction, thereby constituting a guide portion. The shutter 902 includes a pair of rails 912 that are slidably fitted in the guide groove 930 in the longitudinal direction, and a compression coil spring 932 (see FIG. 41) disposed between the rear end surface of the groove 924. The main body 920 is biased in a direction protruding forward.

  As shown in FIG. 41, the forward limit of the shutter 902 by the bias of the spring 932 is such that the engaging protrusion 934 protruding from the upper surface of the shutter 902 is an elongated hole that is an engaging recess formed in the partition wall 926. Defined by engaging the front end face of 936. In this state, the shutter 902 is positioned at a closed position where the opening 910 protrudes forward from the apparatus main body 902 and the rear part, which is the other part in the longitudinal direction of the shutter 902, closes the component discharge port 904. The biasing force of the spring 932 is larger than the biasing force of the spring 494 that biases the shutter 480 of the case 412 toward the closed position. In the component loading apparatus 900, when the component 472 is not loaded into the case 412, the shutter 902 is positioned at the closed position, and the component 472 is prevented from dropping from the accommodation space 923.

  At the time of component insertion, the case 412 is moved toward the component input device 900 in the Y-axis direction with the case 412 positioned in the X-axis direction by the movement of the mounting head 132. Then, as shown in FIG. 45A, the shutter 902 is fitted into the groove 482 and comes into contact with the shutter 480. The case 412 is further moved from this state, but the biasing force of the spring 932 biasing the shutter 902 toward the closed position is larger than the biasing force of the spring 494 biasing the shutter 480 toward the closed position. Therefore, the shutter 902 is not moved with respect to the apparatus main body 920, and the shutter 480 is moved to the open position against the urging force of the spring 494 as shown in FIG. 412 is moved toward the component input device 900.

  In this embodiment, the moving end of the shutter 480 with respect to the case 412 is defined by the guide protrusion 490 coming into contact with the end surface of the guide groove 486 opposite to the guide groove 488 side. Accordingly, the moving end of the shutter 902 with respect to the case 412 is also defined. As shown in FIG. 45B, the shutter 480 is positioned at the open position to open the opening 476 and the opening 910 of the shutter 902 is opened. It will be in a state of overlapping.

  From this state, the mounting head 132 is further moved toward the component loading device 900, but since the movement of the shutter 902 relative to the case 412 is stopped, the case 412 resists the urging force of the spring 932 against the urging force of the spring 932. Move relative to 920. The movement of the shutter 902 is guided by the rail 912 and the guide groove 930. As shown in FIG. 45 (c), the mounting head 132 is moved to a position where the shutter 902 is in the open position and the component discharge port 904 is overlapped with the openings 910 and 476 to be in the open state, and is stopped. It is done. Then, the component conveying belt 750 is moved, and the component 472 is put into the space 470 in the case 412 through the component discharge port 904 and the openings 910 and 476.

  When the component loading is completed, the mounting head 132 is moved away from the component loading device 900. At this time, first, the shutter 902 is moved with respect to the apparatus main body 920 following the case 412 by the bias of the spring 932, and the shutter 902 is moved to the closed position while the shutter 480 is kept in the open position. The component discharge port 904 is closed as shown in FIG. Then, after the engagement protrusion 934 comes into contact with the front end surface of the elongated hole 936 and the movement of the shutter 902 relative to the apparatus main body 920 is stopped, the case 412 has the shutter 902 and the shutter 902, as shown in FIG. The shutter 480 is moved forward by the bias of the spring 494 and the opening 476 is closed.

  As described above, in the component loading apparatus 900 of the present embodiment, the component discharge port 904 is opened and closed by the shutter 902. Therefore, if the shutter 902 is closed after the component loading is completed, the component does not fall from the apparatus main body 920. It is not necessary to return the component conveying belt 750 in order to prevent the components from falling from the leading component receiving recess 804 in which is stored. Even if a component falls from the component receiving recess 804 in a state where the component discharge port 904 is closed by the shutter 902 after the charging, the component 472 is received by the shutter 902. When the component discharge port 904 is opened when the component is put into the case 412 next time, the component 472 is moved with respect to the apparatus main body 920 by the side surface 928 and moved with respect to the shutter 902, and the component discharge port 904 is moved. If opened, it is put into the case 412 through the component discharge port 904 and the openings 910 and 476. In addition, since the component discharge port 904 of the component loading device 900 is opened after the opening 476 of the case 412 and closed first, the component 472 dropped from the component accommodating recess 804 in the accommodating space 923 is other than the case 412. Falling into space is avoided.

When the storage unit of the bulk feeder is removed from the feeder body, a magnet may be provided in the vicinity of the outer periphery of the part forming the component outflow side opening of the storage unit so that the outflow of the component from the storage unit may be prevented. One example will be described with reference to FIGS. 46 and 47. FIG.
The bulk feeder 950 of the present embodiment is configured in the same manner as the bulk feeder 402 except that an electromagnet 952 is provided in place of the shutter 580, and the same reference numerals are given to components having the same functions. The corresponding relationship is shown and the description is omitted.

  The case 960 of the bulk feeder 950 is integrally formed with a portion where the space 470 and the fitting hole 514 are provided, and is a portion where the bush 516 of the fitting hole 514 of the case 960 is fitted, and the lower end position An electromagnet 952 is embedded in a portion that forms a portion above the discharge promoting cylinder 510 located at the position. A pair of electromagnets 952 is provided in the diameter direction of the fitting hole 514.

  As shown in FIG. 47, each of the pair of electromagnets 952 is obtained by winding a coil 964 around an iron core 962, provided in a posture orthogonal to the center line of the fitting hole 514, and each of the pair of electromagnets 952. The coil 964 is wound in the reverse direction. Each coil 964 of the pair of electromagnets 952 is connected to a cord 966, and the cord 966 is connected to a cord 970 connected to a power connector 968 of the mounting head 132 by a plug 972. A switch 974 is provided in the middle of the code 970. The switch 974 is a manual switch whose opening and closing is switched by a manual operation by an operator. By the switching, current is supplied to the two coils 964 and the supply is cut off.

  In a state where the case 960 is attached to the feeder main body 410, the cord 966 is connected to the cord 970, but the switch 974 is open at the open position. Therefore, no current is supplied to the electromagnet 952, the electromagnet 952 is in a demagnetized state, and an outflow allowable state in which the outflow of the component 472 from the opening 517 is allowed.

  When removing the case 960 from the feeder body 410, the operator switches the switch 974 to the closed position. As a result, a current is supplied to each coil 964 of the pair of electromagnets 952 to be in a magnetized state. Different magnetic poles are generated at opposite ends of the iron cores 962 of the two electromagnets 952, and the upper side of the discharge promoting cylinder 510 located at the descending end position in the bush 516 by the magnetic field generated between them. Each of the electrodes of the plurality of components 472 is magnetized. As a result, the components 472 are attracted to each other and connected to each other, and are pressed against the inner peripheral surface of the bushing 516 to prevent a drop from the opening 517.

  Therefore, the operator removes the case 960 from the feeder main body 410 while the electric current is supplied to the electromagnet 952, and makes the part 472 not fall from the case 960 with the opening 517 facing upward. 974 is switched to the open position and the cord 966 is removed from the cord 970. Then, the operator takes the case 960 to the component container provided outside the mounting module 10, opens the shutter 480, discharges the component 472 from the opening 476, and stores it in the component container.

A plurality of component supply tools may be provided, and their supply units may be arranged along an arc that faces the turning trajectory of the suction nozzle associated with the rotation of the rotating body. One example thereof will be described with reference to FIG.
Although not shown in the drawings, the mounting head of the present embodiment is configured in the same manner as the mounting head 132, and the plurality of the five distance maximum stop positions, for example, the most in the rotation direction of the rotating body at the time of component mounting. A total of four distance maximum stop positions adjacent to the upstream maximum distance stop position and the distance maximum stop position are the component receiving positions, and the most downstream distance maximum stop position is the component imaging position.

  One part supply tool, for example, a bulk feeder 980 is provided in each of the parts corresponding to the four parts receiving positions of the head body. The bulk feeder 980 is configured in the same manner as the bulk feeder 402, and as shown conceptually in FIG. 48, the supply unit is provided so as to be positioned immediately below the suction nozzle stopped at the component receiving position. It has been. Different types of parts are accommodated in the respective cases of the bulk feeders 980 at the four parts receiving positions. Further, in the portions corresponding to each of the four component receiving positions of the head main body, an elevating device and a valve switching device configured similarly to the elevating device 262 and the valve switching device 300 are provided.

  In the present embodiment, each of the twelve suction nozzles 172 receives electronic circuit components from the bulk feeder 980 at any one of the four component receiving positions, and electronic circuit components at the other three component receiving positions. The electronic circuit component is imaged at the component imaging position, and the electronic circuit component is mounted on the circuit board at the component mounting position. The twelve suction nozzles 172 mount the electronic circuit components on the circuit board 40 in the order set in the mounting program. For this reason, the types of electronic circuit components received by each of the twelve suction nozzles 172 are determined by the mounting program, thereby determining the component receiving position for receiving the electronic circuit components. If a plurality of suction nozzles are simultaneously positioned at a component receiving position where electronic circuit components are received, the receiving operation is performed simultaneously.

  Unlike the mounting head 132, the mounting head is inclined with respect to a direction perpendicular to the mounting surface of the circuit substrate held by the circuit substrate holding portion, and The nozzle holder is held so as to be able to advance and retreat along the conical surface of the conical surface whose diameter is closer to the rotation axis and farther from the circuit substrate holding part, and that structure constitutes a distance increasing means. It is also possible to do so. One example will be described with reference to FIGS.

  A mounting head 1000 shown in FIGS. 49 to 51 is obtained by adding a plurality (four in the illustrated example) of bulk feeders to the mounting head described in Japanese Patent Laid-Open No. 10-163677. Since it has the substantially same structure except a relevant part, it demonstrates easily. 49, the mounting head 1000 includes a head body 1002 in which a plurality of members are fixed to each other. The head main body 1002 shown in the figure is integrally formed with an X-axis slide that is moved in the X-axis direction by an X-axis servomotor 1004, a screw shaft 1006, and a nut 1008. It is also possible to provide a head body that is configured separately from the X-axis slide and can be attached to and detached from the X-axis slide without using a tool.

  In the head main body 1002, a rotary shaft 1010 is held so as to be rotatable around a rotary axis inclined by 45 degrees with respect to the vertical direction in a vertical plane perpendicular to the Y axis. A rotating disk 1012 perpendicular to the rotation axis is fixed, and these constitute a rotating body 1014. A plurality of nozzle holders 1016 are rotatably held around the rotation axis on the outer peripheral portion of the turntable 1012, and suction nozzles 1018 are detachably held by the nozzle holders 1016. The rotation axes of the nozzle holder 1016 and the suction nozzle 1018 are made coincident with a conical surface generating line whose apex angle is 90 degrees with the rotation axis of the rotation shaft 1010 as a center line. Therefore, as the rotating body 1014 is rotated by the turning servo motor 1020 and the rotation transmitting device 1022, each suction nozzle 1018 turns along the conical surface.

  A hollow shaft 1030 is disposed outside the rotating shaft 1010 so as to be coaxial with the rotating shaft 1010 and rotatable relative to the rotating shaft 1010, and a driving gear 1032 fixed to the lower end of the hollow shaft 1030 includes the nozzle holder. Each of 1016 is meshed with a fixed driven gear 1034. Accordingly, the hollow shaft 1030 is rotated by the nozzle holder rotating servo motor 1036 and the rotation transmitting device 1038, whereby the plurality of suction nozzles 1018 are rotated at the same time and are held by the suction nozzles 1018 (chip parts). 472, the rotation position around the rotation axis of the suction nozzle 1018, that is, the holding direction of the component 472 by the suction nozzle 1018 is changed.

  A bulk feeder 1050 is held in the head main body 1002 in the state shown in FIGS. In FIG. 52, in order to avoid complication, a specific illustration of the mounting head 1000 is omitted, and only the relative positional relationship between the plurality of suction nozzles 1018 and the bulk feeder 1050 is schematically shown. In FIG. 52, the stop position of the rotation axis 1052 of a plurality of (16 in the illustrated example) suction nozzles 1018 is indicated by a one-dot chain line with the intermittent rotation of the rotating body 1014, and the swiveling trajectory 1054 at the tip of the suction nozzle 1018 is set to two. Each case is indicated by a dotted line, and a case (storage part) 1056 and a guide passage 1058 of the bulk feeder 1050 are indicated by solid lines.

  Although the guide passage 1058 is simply indicated by a single solid line, it is actually configured in the same manner as the guide passage 500 and is opposed to the turning trajectory 1054 and is perpendicular to the rotation axis of the suction nozzle 1018 (both in the horizontal and vertical planes). A supply unit 1060 for supplying the component 472 in a state of being supported by the groove bottom surface (inclined with respect to the groove) is provided. As is clear from FIGS. 52B and 52C, the guide passage 1058 extends along a vertical plane perpendicular to the X-axis direction. As shown in FIG. 1062 and an inclined portion 1064 inclined with respect to the horizontal plane. However, as a special case, the uppermost guide passage 1058 in FIG. 52A does not have the vertical portion 1062 (the length of the vertical portion 1062 is 0), and the lowermost guide passage 1058 is inclined. The inclination angle of the portion 1064 is 0.

  The case 1056 is detachable from the head main body 1002, and a discharge promoting device such as the discharge promoting cylinder 510 shown in FIG. 12 and the shutter 580 (or shown in FIG. 46) are provided between the case 1056 and the guide passage 1058. Further, an outflow prevention means such as an electromagnet 952) is provided. The guide passage 1058 includes a vertical portion 1062 and an inclined portion 1064. In these portions, the component 472 is moved to the supply portion 1060 by gravity, but if necessary, as in the above embodiment, the guide is provided. It is also possible to take measures to actively move the part 472 along the passage 1058. Further, although detailed explanation is omitted, when the supply unit 1060 stops the part 472 that has moved in the guide passage 1058 or when one part 472 is taken out from the supply unit 1060, Means are provided to prevent subsequent parts 472 from being pressed and prevented from being removed.

  As shown in FIG. 51, an imaging device 1070 is held by the head body 1002 on the opposite side of the mounting head 1000 from the bulk feeder 1050. The imaging device 1070 includes a light guide device 1074 having a light incident portion 1072 facing the end surface of the suction nozzle 1018 from a direction parallel to the rotation axis of the suction nozzle 1018 at one of the stop positions of the suction nozzle 1018, and the light guide thereof. And a camera 1076 that images an electronic circuit component including the component 472 based on the light guided by the device 1074. The position where the rotation axis of the suction nozzle 1018 of the mounting head 1000 is vertical is the mounting position of the electronic circuit component, and this position is also the position for receiving the component from the component supply device provided stationary. A plurality of tape feeders are arranged along a straight line 1080 shown in FIG.

  Each of the plurality of suction nozzles 1018 receives an electronic circuit component in a state of facing the supply unit 1060 of the plurality of bulk feeders 1050 or the supply unit of the tape feeder as the rotating body 1014 rotates intermittently, and then enters the light incident on the imaging device 1070. The camera stops at the imaging position facing the unit 1072, and the electronic circuit component is imaged at that position. Thereafter, the mounting head 1000 is moved to a position above the circuit board held by the circuit board holding device, and the electronic circuit component is mounted on the circuit board. At this time, the holding position error of the electronic circuit component is corrected by the suction nozzle 1018. At the same time, the holding direction of the electronic circuit component is also changed. The plurality of suction nozzles 1018 are rotated simultaneously by the common nozzle holder rotating servo motor 1036 as described above, and the orientation of each electronic circuit component is set to a predetermined orientation when the electronic circuit component is mounted. Since it is necessary, at the time of imaging by the imaging apparatus 1070, the orientation of the electronic circuit component does not always coincide with the orientation in the mounting state on the circuit board. This point is the same as the mounting head described in Japanese Patent Laid-Open No. 10-163677, but in this embodiment, there is a more unique situation. This will be described below.

As is apparent from FIG. 52, the inclined portion 1064 of the guide passage 1058 does not extend along a plane including the rotation axis of the rotation shaft 1010 and the rotation axis 1052 at each stop position of the suction nozzle 1018. Since the inclination angles with respect to the plane are different from each other, the relative rotation of the component 472 supplied from each of the supply portions 1060 of the plurality of guide passages 1058 to the suction nozzle 1018 with respect to the suction nozzle 1018 in a plane perpendicular to the rotation axis 1052. The position, that is, the holding azimuth of the component 472 by the suction nozzle 1018 differs for each stop position of the suction nozzle 1018. Therefore, there is a unique situation that this fact needs to be taken into account when acquiring the holding orientation error of the electronic circuit component based on the imaging result by the imaging device 1070 and mounting it on the circuit board.
Note that the nozzle holder rotation driving device can rotate each of the plurality of nozzle holders 1016 individually. The same applies to the above embodiments.

  In addition, the component receiver for collecting the electronic circuit components in the bulk feeder may be provided with a component receiving moving device so that it can be automatically moved to the non-accommodating position and the accommodating position. Thus, for example, when the electronic circuit component is sent, the component receiver is positioned at the non-accommodating position, the stopper is positioned at the stop position, the electronic circuit component is stopped at the component extraction position, and the component is removed when the electronic circuit component is extracted by the suction nozzle. Friction is caused between the electronic circuit component taken out by the suction nozzle and the electronic circuit component adjacent to the electronic circuit component upstream in the component movement direction by positioning the receiver at the receiving position and the stopper at the release position. Can be mitigated. After taking out the electronic circuit components, the component receiver is moved to the non-accommodating position, and the stopper is positioned at the stop position. A stopper moving device may be provided together with or instead of the component receiving moving device, and the stopper may be automatically moved to the stop position and the release position with respect to the component receiving.

  Moreover, the component moving part of the bulk feeder may move the electronic circuit components by a device using an electric motor as a drive source, or may arrange the electronic circuit components in a line using a magnet. A component moving device using an electric motor as a driving source includes, for example, an endless belt as a component moving member and a belt circulating device using an electric motor as a driving source, and moves electronic circuit components arranged in a line on the belt. It is supposed to let you.

  Further, when the component loading device is provided with a shutter to open and close the component discharge port, the urging force of the spring for urging the shutter and the shutter of the bulk feeder case toward the closed position is made the same, and the shutter of the component loading device And the shutter of the bulk feeder case may be opened simultaneously and closed simultaneously.

  Further, the moving direction of the plurality of component supply tools on the mounting portion main body is not limited to the Y-axis direction, and may be other directions. For example, it may be moved in the X-axis direction, or may be moved in a direction inclined with respect to the X-axis direction and the Y-axis direction.

  Furthermore, when the first component feeder includes a component feeder and a plurality of component feeders are provided, all of them may be the same type of component feeder, or at least two of them may be different types of component feeders. The same applies to the second component supply tool.
