The outer peripheral edge of the feed amount monitoring dog 100 is pressed against the surface of the cleaning paper P that is wound around the feed roller 94 by an urging means (not shown). When the cleaning paper P is fed from the feed roller 94, the feed amount monitoring dog 100 rotates around the rotation axis A accordingly. At this time, the moving distance of the contact at the outer periphery of the feed amount monitoring dog 100 coincides with the feed amount of the cleaning paper P from the feed roller 94. Therefore, the rotation angle of the feed amount monitoring dog 100 is proportional to the feed amount of the cleaning paper P. The feed amount monitoring switch 102 generates a pulse every time the feed amount monitoring dog 100 rotates by a predetermined rotation angle, that is, every time the cleaning paper P is fed by a predetermined feed amount.

  The solder printing operation of the screen printer 2 will be described. When the circuit board C is sent from the upstream board transfer device, the control device 20 drives the receiving transfer device to receive the circuit board C. The control device 20 includes a Y-direction moving mechanism 40, an X-direction moving mechanism 42, a rotating mechanism 44, and an elevating mechanism so that the X-direction conveying mechanism 48 is in a position where the circuit board C can be received from the receiving and conveying device. 46 is driven. Then, the control device 20 drives the receiving transport device and the X-direction transport mechanism 48 to deliver the circuit board C from the receiving transport device to the X-direction transport mechanism 48.

  When the circuit board C is delivered to the X-direction transport mechanism 48, the control device 20 drives the X-direction transport mechanism 48 to transport the circuit board C to the X-direction position corresponding to the print pattern of the screen mask 28. Then, the control device 20 drives the clamp mechanism 50 and the support mechanism 52 to hold the circuit board C. And the control apparatus 20 images the upper surface of the circuit board C, and the lower surface of the screen mask 28 using an imaging device. The control device 20 processes the image data picked up by the image pickup device and detects a positional deviation between the circuit board C and the screen mask 28. When the positional deviation is detected, the control device 20 drives the Y-direction moving mechanism 40, the X-direction moving mechanism 42, and the rotating mechanism 44 to finely adjust the position of the circuit board C. Then, the control device 20 drives the elevating mechanism 46 to raise the circuit board C and bring the circuit board C into contact with the lower surface of the screen mask 28.

In parallel with the positioning of the circuit board C as described above, the control device 20 supplies solder to the upper surface of the screen mask 28 by the solder supply device. When the circuit board C contacts the lower surface of the screen mask 28 and the solder is supplied to the upper surface of the screen mask 28, the control device 20
After driving one squeegee head (for example, squeegee head 74a) and bringing one squeegee (for example, squeegee 76a) into contact with the upper surface of the screen mask 28, the Y-direction moving mechanism 70 is driven to Perform squeezing on the print pattern. As a result, solder is printed in a pattern corresponding to the print pattern on the circuit board C held in contact with the lower surface of the screen mask 28.

  When the solder printing on the circuit board C is completed, the control device 20 drives the squeegee heads 74a and 74b and the Y-direction moving mechanism 70 to return the squeegee device 30 to the standby position. In addition, the control device 20 drives the lifting mechanism 46, the clamp mechanism 50, and the support mechanism 52 to transfer the circuit board C to the X-direction transport mechanism 48 again. Further, the control device 20 drives the Y-direction moving mechanism 40, the X-direction moving mechanism 42, and the rotating mechanism 44 so that the X-direction conveying mechanism 48 is in a position where the circuit board C can be delivered to the sending and conveying device. To do.

  Then, the control device 20 drives the X-direction transport mechanism 48 and the sending-out transport device, and delivers the circuit board C from the X-direction transport mechanism 48 to the sending-out transport device. Thereafter, the control device 20 drives the delivery / conveyance device to deliver the circuit board C to the downstream substrate conveyance device.

  Hereinafter, the mask cleaning operation of the screen printer 2 will be described. The screen printing machine 2 executes the following mask cleaning operation every time solder printing on a predetermined number of circuit boards C is completed, for example.

  The control device 20 drives the Y direction moving mechanism 80 to move the cleaning device 26 to the cleaning start position. Then, the control device 20 drives the actuator 104 to move the nozzle 106 upward so that the upper surface of the cleaning paper P comes into contact with the lower surface of the screen mask 28. Then, the control device 20 drives the suction device to start suction through the opening of the nozzle 106. In this state, the control device 20 drives the Y-direction moving mechanism 80 to move the cleaning device 26 from the cleaning start position to the cleaning end position in the Y direction. As a result, the cleaning paper P wipes off the dirt on the lower surface of the screen mask 28, and the suction from the nozzle 106 sucks up the dirt on the lower surface of the screen mask 28. When the cleaning device 26 reaches the cleaning end position, the control device 20 finishes the suction by the suction device and drives the actuator 104 to move the nozzle 106 downward to move the cleaning paper P away from the lower surface of the screen mask 28. Let

  Thereafter, the control device 20 performs a cleaning paper P feeding operation in preparation for the next mask cleaning operation. In the feeding operation of the cleaning paper P, the feeding roller 94 has a feeding amount L corresponding to the range of the cleaning paper P used in the cleaning operation of the screen mask 28, that is, a feeding amount L corresponding to the width of the buffer material 108 in the Y direction. The cleaning paper P is wound around the winding roller 88. If the feeding amount of the cleaning paper P at this time can be adjusted accurately, the cleaning operation of the screen mask 28 can be appropriately performed, the waste of the cleaning paper P can be omitted, and the resources can be saved.

  As a method of controlling the feed amount of the cleaning paper P, a method of controlling the operation of the motor 90 based on the feed amount of the cleaning paper P detected by the feed amount detection device 96 can be considered. However, in this system, the adjustment range of the feed amount of the cleaning paper P is limited to the resolution of the feed amount of the cleaning paper P that can be detected by the feed amount detection device 96. In the screen printing machine 2 according to the present embodiment, the adjustment amount of the feed amount of the cleaning paper P is further reduced by controlling the operation of the motor 90 based on the rotation angle of the motor 90 detected by the encoder 92, and thus the high The feeding amount of the cleaning paper P can be adjusted with accuracy.

  As described above, when the operation of the motor 90 is controlled based on the rotation angle of the motor 90 detected by the encoder 92, it is necessary to consider the change in the relationship between the rotation angle of the motor 90 and the feed amount of the cleaning paper P. . As the cleaning paper P is taken up by the take-up roller 88, the radius of the cleaning paper P taken up by the take-up roller 88 gradually increases, so the relationship between the rotation angle of the motor 90 and the feed amount of the cleaning paper P. Will change. Therefore, in the screen printing machine 2 of the present embodiment, in the feeding operation of the cleaning paper P, the control device 20 performs the process shown in FIG.

  In step S2, the control device 20 acquires the feed amount δL of the cleaning paper P per pulse of the encoder 92 used in the current feed operation. As will be described later, this feed amount δL has already been set in the process in the previous feed operation.

  In step S4, the control device 20 determines the encoder 92 based on the feed amount δL of the cleaning paper P per pulse of the encoder 92 acquired in step S2 and the feed amount L of the cleaning paper P necessary for the current feed operation. A feed operation end pulse number Ct for 92 is calculated.

  In step S <b> 6, the control device 20 starts driving the motor 90. Thus, the winding of the cleaning paper P from the feed roller 94 to the take-up roller 88 is started.

  In step S <b> 8, the control device 20 counts the pulses of the encoder 92.

  In step S <b> 10, the control device 20 acquires the number of pulses ΔC of the encoder 92 between the pulses of the feed amount monitoring switch 102. Specifically, every time when the rising edge of the pulse of the feed amount monitoring switch 102 is detected, the control device 20 determines the rising edge of the previous pulse from the accumulated pulse number C2 of the encoder 92 at the time when the rising edge of the current pulse is detected. By subtracting the total number of pulses C1 of the encoder 92 at the time of detecting this, the number of pulses ΔC of the encoder 92 between the pulses of the feed amount monitoring switch 102 is obtained. The value of the number of pulses ΔC is updated each time the control device 20 detects the rising edge of the pulse of the feed amount monitoring switch 102.

  In step S12, it is determined whether or not the cumulative pulse number C of the encoder 92 after the controller 20 starts driving the motor 90 in step S6 has reached the feed operation end pulse number Ct calculated in step S4. to decide. If the integrated pulse number C of the encoder 92 has not reached the feed operation end pulse number Ct (in the case of NO), the process returns to step S8. If the accumulated pulse number C of the encoder 92 has reached the feed operation end pulse number Ct (YES in step S12), the process proceeds to step S14.

  In step S <b> 14, the control device 20 stops driving the motor 90. As a result, the winding of the cleaning paper P from the feeding roller 94 to the winding roller 88 is stopped.

  In step S16, the feed amount δL of the cleaning paper P per pulse of the encoder 92 used in the next feed operation is calculated. The feed amount δL of the cleaning paper P per pulse of the encoder 92 is given by δL = PS / ΔC. Here, PS is a value obtained by converting the pitch of the slit 100a of the feed amount monitoring dog 100 into the length at the outer peripheral edge, and ΔC is a pulse of the encoder 92 between the pulses of the feed amount monitoring switch 102 acquired in step S10. Is a number. After step S16, the process in FIG. 4 ends.

  As described above, according to the screen printing machine 2 of the present embodiment, the feed operation end pulse related to the encoder 92 is used by using the feed amount δL of the cleaning paper P per pulse of the encoder 92 set in the immediately preceding feed operation. The number Ct is calculated and the drive of the motor 90 is controlled. With this configuration, the feed amount L of the cleaning paper P can be adjusted with high accuracy.

  The cleaning paper P of the delivery roller 94 is all taken up by the take-up roller 88, and the operator replaces the set of the feed roller 94 and the take-up roller 88 with an unused set of the feed roller 94 and the take-up roller 88. In this case, the control device 20 automatically performs the cleaning paper P feed operation, and sets the feed amount δL of the cleaning paper P per pulse of the encoder 92 by the processing of FIG. With this configuration, even when the cleaning paper P is replaced, the feeding amount L of the cleaning paper P can be adjusted with high accuracy in the subsequent feeding operation.
