Description

Component mounting system

The present invention relates to a component mounting system composed mainly of a component mounter for mounting components on a substrate.

Equipment that produces boards with a large number of components mounted on them includes solder printers, component mounters, reflow machines, and board inspection machines. It is common to configure a board production line by connecting these facilities in a row. Among these, the component mounting machine includes a substrate transfer device, a component supply device, a component transfer device, and a control device. In general, the component mounter has a control device connected to a host computer in communication with a host computer or connected to equipment on the upstream side or downstream side of the line. As a result, information on the boards and components to be produced, information on the progress of production, and the like are shared, so that production efficiency is improved and quality is maintained. The component mounter functions in an organic manner as a component mounting system in cooperation with a host computer and facilities on the upstream and downstream of the line.

各 Each component mounting machine is often configured to include a detachable or replaceable work unit. For example, the component supply device includes a plurality of feeder units that supply a component by feeding out a carrier tape. In addition, for example, the component transfer apparatus includes a mounting nozzle unit that collects and mounts a component, a mounting head unit that holds the mounting nozzle unit in a replaceable manner, and the like. These work units are provided with an identification code for identifying an individual, thereby facilitating the replacement work by the operator and the automatic replacement operation by the component mounter itself. Japanese Patent Application Publication No. JP-A-2001-259542 discloses a technical example related to an identification code of a work unit installed in a component mounter.

The substrate support unit of Patent Document 1 is a unit that is detachably attached to the backup device, and ID information (identification code) that identifies itself is distinguished from others. Furthermore, a mode of storing this ID information in a storage medium and a mode of associating ID information with production program information are disclosed. According to this, the operator can surely select the substrate support unit based on the ID information, and can confirm that the appropriate substrate support unit is mounted with reference to the ID information.

Unlike Patent Document 1, in the configuration of a component mounter that performs an automatic replacement operation of a work unit, a coordinate value on the component mounter of ID information attached to the work unit is stored in advance. Further, a camera, a barcode reader, or the like that reads the ID information is provided, and the ID information is automatically read to confirm the work unit to be replaced. Further, even in a configuration where the operator performs work unit replacement work, an ID information automatic reading function can be given to the component mounter.

International Publication No. 2005/051066

By the way, the identification code of the work unit and the coordinate value on the component mounter representing the attached position are set in advance and stored in a memory in the control device or a storage device of the host computer. Here, a special work unit may be used depending on the type of substrate to be produced. For example, a warp correction unit may be used to press a positioned substrate to correct the warp. Since the warp correction unit can only press a limited area of the mounting surface of the board where no components are mounted, a new warp correction unit is manufactured and used in accordance with the newly designed board type. No special work unit identification code such as a warp correction unit is set anywhere. Even if the identification code is predetermined, it is difficult to unify the coordinate values to which the identification code is attached because the size and shape of the substrate are various.

For this reason, when a warp correction unit is installed or automatically replaced, it cannot be automatically determined whether or not the warp correction unit is appropriate. At present, when a special work unit such as a warp correction unit is installed, its suitability is confirmed by an artificial method.

The present invention has been made in view of the problems of the background art described above, and a component mounting system capable of automatically confirming the suitability of an equipped work unit when the component mounter is equipped with a special work unit. Providing is a problem to be solved.

The component mounting system of the present invention that solves the above-described problems is equipped with a plurality of work units that are detachably or replaceably mounted in a component mounter and that are provided with identification codes for identifying individuals, and The code reading unit for reading the identification code, the mounting operation is controlled based on job data including information on the identification code of the work unit to be mounted and the mounting operation for mounting the component on the board, and the code reading A component mounting system comprising: a control unit that controls a part; information on identification codes of a part of the work units; and the part on which the identification code is located when the part of the work units is equipped Input means that enables input of coordinate value information on the mounting machine as a set, and the input identification code of the part of the work unit Information, storage means and the to and can be stored in the setting information of the coordinate values, further comprising a.

The component mounting system of the present invention is realized by providing an input unit and a storage unit for a special work unit in which an identification code and its attachment position are not set in advance. The input means can input a set of information on identification codes of some special work units and information on coordinate values on the component mounting machine where the identification codes are located. The storage means can store the input identification code information and coordinate value information as a set. According to this, since the code reading unit can read the identification code of the special work unit based on the stored coordinate value information, the suitability of the equipped special work unit is automatically confirmed.

It is a top view which shows the apparatus structure of the machine component mounting machine used as the center of the component mounting system of embodiment. It is a block diagram which shows the structure of control of the component mounting system of embodiment. It is a figure which illustrates conceptually the job data for producing a board | substrate. It is a figure which illustrates conceptually the unit data which matched the identification code of the standard work unit, and the coordinate value. It is the figure of the control flow which showed the procedure in which a control apparatus controls the mounting operation of a board | substrate based on job data.

(1. Device configuration of the component mounting machine 1)
The apparatus configuration of the component mounter 1 which is the center of the component mounting system 10 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a plan view showing a device configuration of a component mounter 1 that is the center of a component mounting system 10 according to an embodiment. The direction from the left side to the right side in FIG. 1 is the X-axis direction for loading and unloading the substrate K, and the direction from the rear side on the lower side to the front side on the upper side is the Y-axis direction. The component mounter 1 is configured by assembling a substrate transport device 2, a component supply device 3, a component transfer device 4, a component camera unit 5, a control device 6, and the like on a machine base 9. The substrate transfer device 2, the component supply device 3, the component transfer device 4, and the component camera unit 5 are controlled by the control device 6, and each performs a predetermined operation.

The substrate transfer device 2 carries the substrate K (shown with hatching for convenience) into the mounting position, positions and carries it out. The substrate transfer device 2 includes a conveyor unit 21 and a backup device 22 (see FIG. 2) that cannot be seen in FIG. The conveyor unit 21 includes a pair of guide rails and a pair of conveyor belts. The pair of guide rails extends across the center of the upper surface of the machine base 9 in the transport direction (X-axis direction) and is assembled to the machine base 9 in parallel with each other. A pair of endless annular conveyor belts (not shown) are arranged side by side inside the pair of guide rails. The pair of conveyor belts rotate in a state where the long sides facing the substrate K are respectively placed on the conveyor conveyance surface, and carry the substrate K into and out of the mounting position set in the central portion of the machine base 9.

The backup device 22 is disposed below the mounting position. The backup device 22 drives the backup unit with the backup pins up and down. The backup unit pushes up the substrate K, clamps it in a horizontal posture, and positions it at the mounting position. As a result, the component transfer device 4 can perform the mounting operation at the mounting position. Depending on the type of the substrate K, the backup unit is appropriately replaced and installed. An identification code for identifying the individual is attached to the upper surface of the backup unit. As the identification code, a general bar code, a two-dimensional code such as a QR code (registered trademark), or the like can be used. Similar identification codes are also attached to other work units described later.

The warp correction unit 25 is installed on the upper side of the mounting position. The warp correction unit 25 includes a peripheral pressing portion 26, a linear central pressing portion 27, and a crank-shaped central pressing portion 28. The peripheral pressing portion 26 is formed in a frame shape having an opening smaller than the outer shape of the substrate. The warp correction unit 25 is equipped with the long sides facing the peripheral pressing portion 26 fixed to the guide rails. The linear central pressing portion 27 is linearly arranged in the opening while connecting the long sides facing the peripheral pressing portion 26. The crank-shaped central pressing portion 28 is arranged in a shape that bends twice at a right angle within the opening while connecting the long sides facing the peripheral pressing portion 26.

The warp correction unit 25 presses the substrate K positioned on the backup device 22 to correct the warp. In other words, the peripheral pressing portion 26 presses a peripheral region of the mounting surface of the substrate K where no component is mounted. Moreover, the linear center pressing part 27 and the crank-shaped center pressing part 28 press the area | region where components are not mounted among the mounting surfaces of the board | substrate K. As shown in FIG. The warp correction unit 25 is detachably and replaceable depending on the type of substrate K to be produced. That is, when the type of the substrate K to be produced is changed, the warp correction unit 25 becomes unnecessary and is removed. If the type of the substrate K is further changed, another warp correction unit is equipped. As shown in FIG. 1, an identification code 29 is attached to one corner of the peripheral pressing portion 26 of the warp correction unit 25.

The warp correction unit 25 is not normally prepared in advance, and corresponds to a part of the working unit of the present invention. The work units other than the warp correction unit 25 are prepared in advance as standard, and correspond to the remaining work units of the present invention. The warp correction unit 25 can be referred to as a special work unit, and work units other than the warp correction unit 25 can be referred to as standard work units.

Fiducial marks Km are attached to the two corners on the diagonal line of the substrate K, respectively. Further, a substrate type identification code Kc for identifying the type of the substrate K is attached in the vicinity of one fiducial mark Km. The fiducial mark Km and the substrate type identification code Kc are arranged at positions that can be seen through the opening of the warp correction unit 25.

The component supply device 3 sequentially supplies components from the plurality of feeder units 30. The feeder unit 30 has a flat shape with a small size in the width direction, and is arranged side by side on the pallet table 91 on the upper surface of the machine base 9. In the example of FIG. 1, nine feeder units 30 are arranged in a row, and actually a larger number of feeder units 30 are arranged in a row. Each feeder unit 30 includes a main body 31, a tape reel 39 provided at the rear of the main body 31, an identification code 32 provided near the front end of the main body 31, and a component set on the rear side of the identification code 32. It has a supply position 33 and the like. A carrier tape is wound and held on the tape reel 39. The carrier tape is fed out by a predetermined pitch, and the components are released from the stored state and sequentially supplied to the component supply position 33. The plurality of feeder units 30 are appropriately replaced according to the type of substrate K to be produced, and the type of components to be supplied is changed.

The component transfer device 4 picks up and collects components from the component supply device 3, transports them to the positioned substrate K, and mounts them. The component transfer device 4 is an XY robot type device that can move horizontally in the X-axis direction and the Y-axis direction. The component transfer device 4 includes a pair of Y-

axis rails

41 and 42 and a Y-axis slider 43, a mounting head unit 44, a mounting nozzle unit 45, a suction nozzle 46, and a substrate camera that constitute a head driving unit 48 (see FIG. 2). The unit 47 is configured. The pair of Y-

axis rails

41 and 42 are disposed near both side surfaces of the machine base 9 and extend in the front-rear direction (Y-axis direction). A Y-axis slider 43 is movably mounted on the Y-

axis rails

41 and 42. The Y-axis slider 43 is driven in the Y-axis direction by an unillustrated Y-axis ball screw mechanism.

The mounting head unit 44 is movably mounted on the Y-axis slider 43. The mounting head unit 44 is driven in the X-axis direction by an unillustrated X-axis ball screw mechanism. The mounting nozzle unit 45 is held by the mounting head unit 44 in a replaceable manner. The mounting nozzle unit 45 has one or a plurality of suction nozzles 46 for sucking components and mounting them on the substrate K. An identification code is attached below the mounting nozzle unit 45.

The mounting nozzle unit 45 and the suction nozzle 46 can be replaced by an operator. However, the mounting nozzle unit 45 and the suction nozzle 46 may be automatically replaced. That is, a configuration of the component mounting machine 1 may be employed in which a replacement station for holding the replacement mounting nozzle unit 45 and the suction nozzle 46 is provided on the machine base 9 and the mounting head unit 44 has an automatic replacement function.

The substrate camera unit 47 is provided in the mounting head unit 44 along with the mounting nozzle unit 45. The substrate camera unit 47 images the fiducial mark Km attached to the substrate K and detects the accurate position of the substrate K.

Furthermore, the substrate camera unit 47 moves within a movable range by driving from the head drive unit 48, and can image and read the identification code that has entered the imaging field of view. Specifically, the substrate camera unit 47 reads the substrate type identification code Kc of the substrate K, the identification code 29 of the warp correction unit 25, and the identification code 32 of the feeder unit 30. Further, the substrate camera unit 47 reads the identification code of the backup unit before the substrate K is loaded. The board camera unit 47 is an embodiment of the code reading unit of the present invention.

The component camera unit 5 is provided upward on the upper surface of the machine base 9 between the substrate transfer device 2 and the component supply device 3. The component camera unit 5 images the state of the component sucked by the suction nozzle 46 while the mounting head unit 44 moves from the component supply device 3 onto the substrate K. When the image pickup data of the component camera unit 5 reveals an error in the component adsorption posture, a shift in the rotation angle, and the like, the control device 6 finely adjusts the component mounting operation as necessary. Control to dispose of parts. The component camera unit 5 can image and read the identification code of the mounted nozzle unit 45 equipped.

(2. Configuration of control of component mounting system 10 of embodiment)
The control device 6 is a computer device having a CPU and operating with software. FIG. 2 is a block diagram illustrating a control configuration of the component mounting system 10 according to the embodiment. As shown in FIG. 2, the control device 6 is communicatively connected to the substrate transfer device 2, the component supply device 3, the component transfer device 4, and the component camera unit 5. Further, the control device 6 is also connected to a host computer 7 for communication. The control device 6 includes an input unit 61 that performs input settings by an operator, a display unit 63 that displays information to the operator, and a storage unit 62 that stores various programs and data. Similarly, the host computer 7 includes an input unit 71, a display unit 73, and a storage unit 72.

The control device 6 appropriately issues commands to the devices 2 to 5 based on the job data 64 to control the mounting operation. FIG. 3 is a diagram conceptually illustrating job data 64 for producing the substrate K. The job data 64 is data that sequentially describes the mounting operation for mounting the component on the board K, and instructs the operation content of the component mounting machine 1. The job data 64 is generated by, for example, application software that simulates the optimization of the mounting operation.

The name 65 of the job data 64 is represented by “JOBSP001” in which three fixed alphabetic characters “JOB” and five characters “SP001” representing the type of the substrate K are connected. The name 65 of the job data 64 matches the board type identification code Kc. That is, the substrate type identification code Kc of the substrate K is “JOBSP001”.

In the job data 64, information on the identification code of the work unit used for the mounting operation is described. For example, the identification code of the mounting nozzle unit 45, which is a standard work unit, is described with five characters such as “NA001”, “NA002”, “NA003”, and the like. The two characters “NA” on the front side indicate that it is the mounting nozzle unit 45, and the three-digit number on the rear side indicates the individual of the mounting nozzle unit 45. Further, for example, the identification code 32 of the feeder unit 30 which is a standard work unit is described by five characters such as “NB001”, “NB002”, “NB003”, and the like. The two characters “NB” on the front side represent the feeder unit 30, and the three-digit number on the rear side represents the individual of the feeder unit 30. Further, in the case of the feeder unit 30, the arrangement position i (i = 1 to 9) on the component supply device 3 is written after the identification code 32 in the job data 64.

The control device 6 refers to the unit data 67 when the job data 64 includes the identification code information of the standard work unit. FIG. 4 is a diagram conceptually illustrating the unit data 67 in which the identification code of the standard work unit and the coordinate value are associated with each other. In the unit data 67, the coordinate value on the component mounter 1 where the identification code is located when the standard work unit is installed is preset. In the example of FIG. 4, the same coordinate value PA (XA, YA) is uniformly set for all the identification codes (“NA001”, “NA002”, etc.) of the mounting nozzle unit 45. That is, all kinds of mounting nozzle units 45 are provided with identification codes at the same position.

Similarly, coordinate values PBi (XBi, YB) are uniformly set for all the identification codes 32 (“NB001”, “NB002”, etc.) of the feeder unit 30. That is, all types of feeder units 30 are provided with the identification code 32 at the same position. However, in the feeder unit 30, when the arrangement position i (i = 1 to 9) on the component supply device 3 changes, the X coordinate value XBi changes correspondingly, and the Y coordinate value YB does not change.

In FIG. 2, the job data 64 and the unit data 67 are stored in the storage unit 62 of the control device 6. However, the present invention is not limited to this. That is, the job data 64 and the unit data 67 may be stored in the storage unit 72 of the host computer 7 or an external storage device (not shown) accessible by the control device 6.

On the other hand, neither the identification code 29 nor the coordinate value is set in advance for the warp correction unit 25 which is a special work unit. In the present embodiment, the identification code 29 and coordinate value information of the warp correction unit 25 are stored in the job data 64 by an input unit and a storage unit described later.

(3. Operation and Action of Component Mounting System 10 of Embodiment)
Next, operations and effects when the board K is produced using the component mounting system 10 of the embodiment will be described in order from the setup work before actual production. At the beginning of the setup operation, the operator determines the identification code 29 of the warp correction unit 25. Although there are no particular restrictions on the method of determining the identification code 29, it is advisable to associate the type of the substrate K with the warp correction unit 25 in view of the limited use range of the warp correction unit 25. It is. Specifically, the front three characters “JOBSP001”, which is the substrate type identification code Kc of the substrate K, are omitted, and the five characters “SP001” are used as the identification code 29 of the warp correction unit 25.

Similarly, the identification code of the warp correction unit equipped when producing the substrate K whose substrate type identification code Kc is “JOBSP102” can be “SP102” of 5 characters. Furthermore, when a certain warp correction unit is used for the production of two or more types of substrates, a wild card (a symbol such as “*”) can be used to represent the identification code of the warp correction unit. For example, when a certain warp correction unit is used for the production of three types of substrates represented by board type identification codes “JOBSP211”, “JOBSP212”, and “JOBSP213”, the identification code of a certain warp correction unit is set to “SP21”. * ". As described above, when the substrate type identification code of the substrate and the identification code of the warp correction unit are associated with each other, the operator can accurately determine the warp correction unit to be equipped in accordance with the type of substrate to be produced. Easy to select.

The operator attaches a label with an identification code 29 of “SP001” to the warp correction unit 25. The method of attaching the identification code 29 is not limited to label affixing, and may be another method such as printing. Further, the operator calculates the coordinate value P1 (X1, Y1) on the component mounter 1 where the identification code 29 is located when the warp correction unit 25 is installed. The coordinate value P1 (X1, Y1) can be calculated by measurement using an actual machine or a jig, calculation based on design data, or the like. The determination of the identification code 29 of the warp correction unit 25 and the calculation of the coordinate value P1 (X1, Y1) are operations only at the first use, and are unnecessary at the second and subsequent uses.

Next, the operator inputs information (“SP001”) of the identification code 29 of the warp correction unit 25 from the input unit 61 of the control device 6 and the coordinate value where the identification code 29 is located when the warp correction unit 25 is equipped. The information of P1 (X1, Y1) is input as a set. Therefore, the input unit 61 corresponds to the input unit of the present invention. As a result, in the storage unit 62, the information (“SP001”) of the identification code 29 of the warp correction unit 25 and the information of the coordinate value P1 (X1, Y1) are stored in the job data 64 as a set. The stored state is shown in FIG. Therefore, the storage unit 62 corresponds to the storage unit of the present invention.

Note that the input operation and the storage operation corresponding to the input unit and the storage unit need to be performed for a plurality of types of warp correction units having different shapes and a plurality of job data different from each other. Since the job data 64 is stored in the storage unit 62, the input unit 61 is used as an input unit and the storage unit 62 is used as a storage unit. However, the present invention is not limited to this. That is, the input unit and the storage unit can be realized by using the input unit 71 and the storage unit 72 of the host computer 7.

Thereafter, when the operator actually installs the warp correction unit 25 on the guide rail of the substrate transport apparatus 2, the setup work is completed. Next, the control device 6 shifts to the production of the substrate K. FIG. 5 is a control flow diagram illustrating a procedure in which the control device 6 controls the mounting operation of the substrate K based on the job data 64. Based on the sequential instruction contents of the job data 64, the control device 6 performs control to perform the instructed operation using the instructed work unit.

In step S1 of FIG. 5, the control device 6 determines whether or not the instruction content of the job data 64 includes a work unit identification code. If there is no identification code, the control device 6 advances the execution of the control flow to step S2, and if there is an identification code, advances the execution of the control flow to step S3. In step S2, the control device 6 performs control to perform the instructed operation, returns the execution of the control flow to step S1, and moves to the next instruction content.

In step S3, the control device 6 determines whether or not the identification code represents a special work unit, that is, the warp correction unit 25. The control device 6 determines whether it is a standard work unit or a special work unit based on the two front characters of the identification code represented by five characters. In the former case, the control flow proceeds to step S4. In this case, the control flow is advanced to step S7.

In step S4 in the case of the standard work unit, the control device 6 specifies the type of the standard work unit based on the two characters on the front side of the identification code. In step S5 when the standard work unit is the mounting nozzle unit 45, the control device 6 controls the head drive unit 48 and the component camera unit 5 based on the coordinate value PA (XA, YA) in the unit data 67. The head drive unit 48 recognizes the coordinate value PA (XA, YA) as an imaging position and moves the mounting nozzle unit 45. Next, the component camera unit 5 images and reads the actual identification code of the mounting nozzle unit 45.

Further, in step S <b> 6 when the standard work unit is the feeder unit 30, the control device 6 controls the head drive unit 48 and the substrate camera unit 47 based on the coordinate value PBi (XBi, YB) in the unit data 67. . The head drive unit 48 recognizes the coordinate value PBi (XBi, YB) as the imaging position based on the known line position i, and moves the board camera unit 47. Next, the substrate camera unit 47 images and reads the actual identification code 32 of the feeder unit 30. Although omitted in FIG. 5, the control device 6 similarly controls other standard work units to read an actual identification code.

In step S7 in the case of a special work unit, the control device 6 determines the head drive unit 48 and the board camera unit based on the coordinate value P1 (X1, Y1) stored in the job data 64 as a set with the identification code 29. 47 is controlled. The head drive unit 48 recognizes the coordinate value P1 (X1, Y1) as the imaging position and moves the substrate camera unit 47. Next, the substrate camera unit 47 images and reads the actual identification code 29 of the label attached to the warp correction unit 25.

Step S5, step S6, and step S7 in the control flow subsequently merge into step S8. In step S8, the control device 6 determines whether or not the read identification code information matches the identification code information in the job data. If they match, the control device 6 determines that the work unit is correctly equipped, returns the execution of the control flow to step S1, and moves to the next instruction content. If they do not match, and if the identification code cannot be read, the control device 6 advances the execution of the control flow to step S9.

In step S9, the control device 6 determines that the work unit is misequipped or not equipped, and notifies the operator. It is preferable that the contents of the notification not only indicate misequipment or not equipped, but also display a correct work unit guidance display. For example, using the identification codes n, k, etc., a guidance display is displayed as “work unit k equipped with coordinate value P (n) is misequipped, so equip regular work unit n”. Further, for example, a guidance display is displayed as “Work unit n is not equipped at coordinate value P (n).

After step S9, the control flow is interrupted until correction is performed by the operator. Then, based on the resume command input after the operator finishes the correction work, the control device 6 resumes the execution of the control flow from the commanded location of the job data 64.

(4. Aspects and effects of the component mounting system 10 of the embodiment)
The component mounting system 10 of the embodiment is detachably or replaceably mounted in the component mounter 1, and has a plurality of work units provided with an identification code for identifying an individual, and an identification code of the equipped work unit Mounting operation based on job data 64 describing mounting operation for mounting a component on a substrate K including information on the identification code of the work unit to be mounted and board camera unit 47 and component camera unit 5 (code reading unit) And a control device 6 for controlling the code reading unit, the component mounting system 10 including the identification code 29 information of the warp correction unit 25 (part of the work unit) and the warp correction unit 25. Information of the coordinate value P1 (X1, Y1) on the component mounter 1 where the identification code 29 is located is set. The input unit 61 (input means) that can be input and the input information of the identification code 29 of the warp correction unit 25 and the information of the coordinate value P1 (X1, Y1) can be stored as a set. And a unit 62 (storage means).

The component mounting system 10 according to the embodiment is realized by including an input unit and a storage unit for a special warp correction unit 25 in which an identification code and an attached position thereof are not set in advance. The input unit 61 (input means) can input the information of the identification code 29 of the warp correction unit 25 and the information of the coordinate value P1 (X1, Y1) on the component mounter 1 where the identification code 29 is located as a set. . The storage unit 62 (storage means) can store the input information of the identification code 29 and the information of the coordinate value P1 (X1, Y1) as a set. According to this, since the board camera unit 47 (code reading unit) can read the identification code 29 of the warp correction unit 25 based on the information of the stored coordinate value P1 (X1, Y1), it is equipped. Appropriateness of the warp correction unit 25 is automatically confirmed.

Further, the storage unit 62 can store the information of the identification code 29 of the warp correction unit 25 and the information of the coordinate value P1 (X1, Y1) in the job data 64 as a set. According to this, since the information regarding the warp correction unit 25 is completed in the job data 64, the present invention can be implemented regardless of the type of application software that generates the job data 64. Further, there is no need to sequentially upgrade application software.

Further, in the component mounting system 10 according to the embodiment, if the job data 64 includes the information (“SP001”) of the identification code 29 of the warp correction unit 25 in the job data 64, the control device 6 is stored as a set with the identification code 29. The board camera unit 47 (code reading unit) reads the identification code 29 of the warp correction unit 25 based on the coordinate information P1 (X1, Y1), and the information of the read identification code 29 is the job data 64. The warp correction unit 25 is determined to be correctly equipped, and the read identification code information does not match the identification code information in the job data 64, and If the substrate camera unit 47 cannot read the identification code 29, another work unit is erroneously installed, Rui will be notified to be unequipped.

According to this, it is possible to reliably detect an operation error of an operator who is equipped with an erroneous work unit other than the warp correction unit 25 or which is not equipped with the warp correction unit 25. Therefore, the substrate K is not erroneously generated due to incorrect use of the work unit or non-use of the work unit.

Further, a board type identification code Kc for identifying the type of the board K is attached to the board K, and the board type identification code Kc (“JOBSP001”) of the specific board K on which the component is mounted with the warp correction unit 25 mounted. And the identification code 29 (“SP001”) of the warp correction unit 25 are associated with each other. According to this, the operator can accurately and easily select the warp correction unit 25 to be equipped in accordance with the type of the substrate K to be produced, so that the possibility of misequipment or not equipped is reduced.

Further, the standard work units (remaining work units) other than the warp correction unit 25 have the coordinate values (PA, PBi, etc.) on the component mounter 1 where the identification code is located in the unit data 67 in advance when equipped. It is set, and input setting by the input unit 61 (input means) is unnecessary. According to this, since the input setting only needs to be performed when a special work unit such as the warp correction unit 25 is equipped, the operator's setting work is light.

Further, the component mounting system 10 according to the embodiment includes a conveyor unit 21 that carries a substrate K in and out, a substrate transfer device 2 that has a backup unit that pushes up the substrate K and positions it at a mounting position, and a plurality of feeders that supply components. A component supply device 3 having a unit 30, a mounting nozzle unit 45 that collects components from the component supply device 3 and mounts them on a positioned substrate K, and a mounting head unit 44 that holds the mounting nozzle unit 45 in a replaceable manner. A component transfer device 4 and a warp correction unit 25 which corresponds to a special work unit and is detachably mounted on the upper side of the conveyor unit 21 and presses the substrate K positioned on the backup unit to correct the warp. It is provided in the mounting machine 1.

According to this, the present invention can be implemented for the component mounter 1 that is detachably equipped with the warp correction unit 25, and the above-described effects become remarkable.

Further, the board camera unit 47 provided in the mounting head unit 44 images the fiducial mark Km attached to the board K to confirm the position of the board K, and also serves as a code reading unit. According to this, since a dedicated code reading unit for reading the identification code 29 of the warp correction unit 25 is not required, an increase in cost is suppressed.

(5. Application and modification of embodiment)
The identification code 29 and the coordinate value P1 (X1, Y1) of the warp correction unit 25 do not necessarily have to be stored in the job data 64. For example, it is possible to generate special unit data to be stored by setting the identification code 29 and the coordinate value P1 (X1, Y1), and indicate only the identification code 29 in the job data 64. As can be seen from this example, various modifications can be considered for the storage structure of various data relating to the mounting operation.

Furthermore, there are various types of standard work units and special work units other than those described in the embodiments, and the present invention can be applied as appropriate. The various identification codes described in the embodiments are examples, and various other identification code systems can be used. Various other applications and modifications are possible for the present invention.
