  This solder printing machine includes a controller 80 as a control device that controls itself by controlling the various devices described above (see FIG. 2), and as an input / output terminal of the controller 80. And an operation panel 82 having a display and input keys (see FIG. 1). When the operator performs an operation for starting the printing operation on the operation panel 82, under the control of the controller 80, the solder printing operation on the board is executed according to the work program corresponding to the type of the board.

  The printing operation by the solder printer will be described. First, the board is carried by the board conveying device 12 so as to pass through the opening (see FIG. 1) provided in the exterior panel, and the setting of the intermediate section 48 is performed. Stopped in position. Next, by raising the table 54 of the substrate holding / elevating device 32, the substrate is lifted from the conveyor to a position where it can be clamped by the clamp 58 while being supported by the backup block 59. And clamped by the clamp 58. In this state, the camera 70 of the mark imaging device 34 takes an image of the position reference mark (fiducial mark) attached to the surface (upper surface) of the substrate, and also applies the scan position attached to the lower surface of the screen 72. A reference mark (fiducial mark) is imaged. Based on the image data obtained by the imaging, the screen position adjustment device 32 aligns the screen 16 with the substrate. After the alignment, the substrate is lifted together with the table 54 to a position where it hits the lower surface of the screen 72 while being sandwiched by the clamps 58.

The squeegee 20 being moved down by 22 is moved in one direction in the front-rear direction. That is, a predetermined printing operation is performed. Specifically, when the squeegee being lowered 20 is the front side, the squeegee 20 is moved rearward. When the squeegee 20 is the rear side, the squeegee 20 is moved forward. The solder is supplied on the upper surface of the screen 16, and a plurality of openings are formed in the screen 16 in a pattern set according to the substrate. As the squeegee 20 moves forward or backward, the solder passes through the openings and is printed on the substrate.

  The substrate on which printing has been completed is lowered together with the table 54. After the clamping by the clamp 58 is released, the table 54 is further lowered to place the substrate on the conveyor. Thereafter, the substrate is carried out of the solder printer from the opening provided in the exterior panel by the substrate transfer device 12. By repeating such a series of operations, printing operations for a plurality of substrates are sequentially and continuously executed.

≪Work device management≫
The solder printer is provided with various working devices that are exchanged according to the type of board, that is, the type of printing work to be performed. Specifically, each of the screen 16, the squeegee 20, and the backup block 59 described above corresponds to the working device, and the screen 16, the squeegee 20, and the backup block 59 (hereinafter collectively referred to as “working device”). Management of the working device for the target device may be performed by the controller 80.

  Specifically, the number, position, and size of the openings formed in the screen 16 differ depending on the shape, size, arrangement, and the like of the solder pads (solder lands) to be printed. In addition, the squeegee 20 has a different shape, length, hardness, and the like depending on the size of the substrate (the area where the screen 16 is used), the type of solder, and the like. Further, the backup block 59 is sized according to the size of the board, whether or not the solder is printed on the surface opposite to the surface on which the components are already mounted, and the like. The presence / absence, size, number, position, etc. of the escape holes 86 (see FIG. 3) of the parts are different. Therefore, the screen 16, the squeegee 20, and the backup block 59 (hereinafter, may be collectively referred to as “real device”) that are actually attached are appropriate according to the type of the substrate, that is, the type of printing work to be performed. It must be something. That is, it must be an appropriate screen 16 to be attached, a squeegee 20, and a backup block 59 (hereinafter may be collectively referred to as “appropriate device”). In view of this, the present solder printer is configured such that the controller 80 determines whether or not the actual device is a proper device.

  Information that can identify an appropriate device, that is, appropriate device information is stored in the controller 80. Specifically, the information that is the basis of the appropriate device information is included in the above-described work program, and the controller 80 acquires the appropriate device information based on the included information and stores it in itself. It is configured as follows.

  On the other hand, information that can identify a real device, that is, real device information is obtained by the controller 80. The work device is provided with an indicator (a kind of identifier) that displays identification information, that is, information for identifying itself including ID information (individual identification information). Specifically, the screen 16 is provided with a two-dimensional code (QR code (registered trademark)) 88 at the lower corner, and the squeegee 20 is provided with a barcode 90 on the outer surface (see FIG. In the backup block 59, a two-dimensional code (which is a QR code (registered trademark)) 92 is attached to the upper corner (see FIG. 3). Based on the ID information displayed by these indicators, actual device information is obtained. The two-dimensional codes 88 and 92 attached to the screen 16 and the backup block 59 are picked up by the camera 70 of the mark image pickup device 34 under the control of the controller 80, and the identification information is based on the image pickup data. To be acquired. On the other hand, the identification information displayed by the bar code 90 attached to the squeegee 20 is read by a bar code reader 94 (see FIG. 1), which is a reader connected to the controller 80, by the operation of the operator. The controller 80 is configured to obtain actual device information based on the identification information acquired or read as described above.

  Replacement of the screen 16, the squeegee 20, and the backup block 59, which are the target work devices, is performed with the door 96 constituting a part of the exterior panel opened while the printing operation is stopped (see FIG. 1). In the case where there is a possibility that the replacement has been performed by the operator, the controller 80 determines whether or not the actual device is a proper device. More specifically, the determination as to whether or not the work device can be replaced will be described. Since the screen 16 and the backup block 59 are replaced while the printing operation is stopped, the controller 80 performs the printing operation. Is restarted, it is determined that the screen 16 and the backup block 59 may have been replaced. On the other hand, the squeegee 20 is determined on the basis of a change in a measured value by a load cell 98 (see FIG. 2) which is a squeegee weight measuring device provided in the squeegee lifting device 28. Specifically, the pair of load cells 98 provided corresponding to each of the pair of squeegees 20 can measure the weight of the attached squeegees 20 and the measured values by the load cells 98 are measured. Is sent to the controller 80 as a signal, and the controller 80 is configured to monitor the measured value. When the controller 80 determines that both of the pair of squeegees 20 are attached from the state in which at least one of the pair of squeegees 20 is removed as a result of the monitoring, the squeegee 20 Is considered to have been exchanged.

  The operation of the controller 80 when it is determined that the work device may be replaced will be described. When it is determined that the screen 16 and the backup block 59 may be replaced, as described above. The controller 80 reads the two-dimensional codes 88 and 92 attached to the screen 16 and the backup block 59 by controlling the mark imaging device 34. On the other hand, if it is determined that the squeegee 20 may be replaced, an instruction “squeegee suitability check” is displayed on the display of the operation panel 82, and the bar code 90 is read by the operator using the bar code reader 94. Encourage action. As a result of such operation, actual device information is obtained as described above.

  When it is determined that the actual device is not a proper device, the controller 80 displays on the display of the operation panel 82 that the actual device is not a proper device, that is, the fact that “work device is inappropriate”. The resumption of the printing work to be resumed is prohibited, or the execution of the printing work is prohibited.

  The management of the working device described above is performed by executing a device management program by the controller 80. Specifically, the screen 16 and the backup block 59 are executed by executing the first device management program shown in the flowchart in FIG. 4, and the squeegee 20 is executed by the second device management program shown in the flowchart in FIG. Is done. These programs are repeatedly executed with a short time interval until the operation of the solder printer is stopped, triggered by the start of the operation of the solder printer (which means that the main switch is turned on). Is done.

  The following processing is performed by executing the first device management program. First, in S1 (“S” means a step), it is determined whether or not the printing operation has been resumed. When the printing operation is resumed, it is determined that at least one of the screen 16 and the backup block 59 may have been replaced, and the two-dimensional codes 88 and 92 are imaged by the mark imaging device 34 in S2. The actual device information is obtained based on the identification information acquired by the imaging. In S3, the actual device is identified based on the obtained actual device information, and in S4, the appropriate device is identified based on the stored proper device information. In S5, the identified actual device and the appropriate device are identified. Based on the device, it is determined whether or not the real device is a proper device, that is, whether or not the real device is suitable. If it is determined that the actual device is not appropriate, specifically, if at least one of the attached screen 16 and backup block 59 is inappropriate, the display on the operation panel 38 is displayed in S6. In addition, a message indicating that one or both of the screen 16 and the backup block 59 is inappropriate is displayed, and in S7, the printing operation is prohibited, more specifically, the restarting of the printing operation to be resumed is prohibited. By the process of S8, the prohibition of the printing work is continued until the operator inputs to the operation panel 82 for resetting the program after being replaced with an appropriate working device. When it is determined in S1 that the printing work has not been resumed (this is a concept including that the printing work is continuing), or in S5, when the actual device is determined to be appropriate Alternatively, when it is determined in S8 that a reset input has been made, one execution of the program ends.

On the other hand, the following processing is performed by executing the second device management program. First, in S11, the measured value W _S of the load cell 98 is recognized. Subsequently, in S12 to S16, determination regarding the measured value W _S and update processing of the flag F _S are executed. Flag F _S is the measured value W _S is the threshold W _S - is a "1" is less than _TH, the measured value W _S is the threshold W _S - be a flag that is set to "0" in the case where _TH or more The initial value is “0”. The threshold value W _{S -TH} is a measured value when it can be recognized that both of the pair of squeegees 20 are attached, and a measured value when it can be recognized that only one of the pair of squeegees 20 is attached. When the flag F _S is “0”, the state in which both of the pair of squeegees 20 are attached is “1”. The state where at least one of the pair of squeegees 20 is removed is shown. Therefore, it is determined that there is a possibility that at least one of the pair of squeegees 20 has been exchanged when the flag F _S value changes from “0” to “1” by the processing based on the measurement value W _S of the load cell. Can do it.

  If it is determined that there is a possibility that at least one of the pair of squeegees 20 has been replaced by the processing of S12 to S16, in S17, an indication for confirming the suitability of the squeegee 20, that is, a barcode reader. A display indicating that the bar code 90 attached to the squeegee 20 is to be read by 94 is displayed on the display of the operation panel 82, and the operation of the operator is prompted. When the identification information of the squeegee 20 is acquired as a result of reading by the barcode reader 94 in S18, the actual device information is obtained based on the acquired identification information in S19. In S20, the actual device is identified based on the obtained actual device information, and in S21, the appropriate device is identified based on the stored proper device information. In S22, the identified actual device and the appropriate device are identified. Based on the device, it is determined whether or not the real device is a proper device, that is, whether or not the real device is suitable. If it is determined that the actual device is not appropriate, specifically, if at least one of the pair of attached squeegees 20 is inappropriate, the display of the operation panel 38 is displayed in S23. A message indicating that the squeegee 20 is inappropriate is displayed, and the printing operation is prohibited in S24. By the process of S25, the prohibition of the printing work is continued until the operator inputs to the operation panel 82 for resetting the program after being replaced with an appropriate working device.

  If it is determined that none of the pair of squeegees 20 has been replaced by the processing of S12 to S16, if it is determined in S22 that the actual device is appropriate, or in S25, If it is determined that there has been a reset input, one execution of the program ends.
