First and second substrate loading positions 17 and 18 comprising a conveyor 35 are provided. The printed circuit boards 11 to be produced are loaded into the first and second board loading positions 17 and 18 (first and second conveyors 34 and 35) by the workers M1 and M2 and are on standby. When the printed circuit board 11 is loaded into the first board loading positions 17 and 18, this is detected by the sensors 37 and 38, and a detection signal is output to the control device 39. When the printed circuit board 11 waiting on the first and second conveyors 34 and 35 can be carried into the printing work position of the screen printing machine 12, the board is conveyed according to the order of waiting on the first and second conveyors 34 and 35. It is transported to the device 24 and carried into the printing work position by the substrate transport device 24.

  At this time, when the printed board 11 is carried from the first board loading position 17 to the printing work position, the original first board loading position 17 is obtained by the first transport path T1 indicated by arrows a1 and a2 in FIG. When the second substrate loading position 18 is loaded into the printing work position, the second substrate loading position 17 is discharged through the second transport path T2 indicated by arrows b1 and b2 in FIG. The conveyance is controlled as follows.

  The screen printing machine 12 is provided with a robot 41 having a movable part 40 movable in a three-dimensional direction. A camera 42 that reads the mark 11 a on the printed circuit board 11 is attached to the movable portion 40 of the robot 41. Further, a stopper 43 for positioning the printed circuit board 11 at a printing work position (center position) of the screen printing machine 12 below the screen mask 27 and two sensors 44 and 45 for positioning detection are attached to the movable portion 40. ing. The robot 41 can move the movable unit 40 in accordance with the loading direction of the printed circuit board 11 to control the position of the stopper 43, thereby positioning the printed circuit board 11 at the printing work position of the screen printing machine 12. As a result, the printed circuit board 11 carried in from the first substrate loading position 17 (first conveyor 34) side or the second substrate loading position 18 (second conveyor 35) side is brought into contact with the stopper 43 and is brought into the printing work position. Positioned. At this time, if the printed circuit board 11 is loaded and positioned from the first board loading position 17 side, this is detected by one sensor 44, and conversely, the printed board 11 is loaded from the second board loading position 18 side. If it is positioned, this is detected by the other sensor 45.

  The printed circuit board 11 positioned at the printing work position of the screen printer 12 is held by the board holding device 21 (see FIG. 2). The printed circuit board 11 held by the substrate holding device 21 is moved up and down by the substrate holding device lifting device 26 and brought into contact with the lower surface of the screen mask 27.

  Next, the operation of the substrate production apparatus in the first embodiment described above will be described using the flowchart of the substrate production program shown in FIG. The board production program is repeatedly executed by the control device 39 at regular time intervals (ms).

  In the following description, a state where the printed board 11 is not present at the printing work position of the screen printer 12 is referred to as a board waiting state. Further, the printed circuit boards 11 loaded into the first board loading position 17 and the second board loading position 18 are the same, but for convenience of explanation, the printed board 11 loaded from the first board loading position 17 is referred to as the board A. The printed circuit board 11 carried in from the second substrate loading position 18 is referred to as a substrate B.

  First, the workers M1 and M2 put the substrates A and B to be produced into the first and second substrate loading positions 17 and 18 of the screen printer 12. When the substrates A and B are loaded into the substrate loading positions 17 and 18, they are detected by the sensors 37 and 38 installed at the substrate loading positions 17 and 18, and based on this signal, the substrate A signal or the substrate B signal is detected. Is issued, and processing is executed with priority given to the earlier board presence signal.

  In the flowchart of FIG. 4, in step 100, it is determined whether or not the substrate A is present at the first substrate loading position 17. If the determination result in step 100 is NO (N), the process proceeds to step 102. It is determined whether or not the substrate B is present at the two substrate loading position 18. If the determination result in step 100 is YES (Y), the presence of the substrate A is stored in the first substrate loading position 17. If the determination result in step 102 is YES, the substrate B is positioned in the second substrate loading position 18. Yes is remembered. As a result, whether the substrate to be loaded with priority is A or B is stored and held.

  Next, at step 104, it is determined whether or not the substrate is waiting. If the determination result is NO, the program is returned. If the determination result in step 104 is YES, that is, it is determined that the substrate is in a waiting state, the process proceeds to step 105, and if the substrate to be preferentially loaded is A, the process proceeds to step 106 and preferentially. If the substrate to be loaded is B, the process proceeds to step 108. In step 106, the first conveyor 34 on the first substrate loading position 17 side and the transport conveyor 33 of the substrate transport device 24 are placed on the substrate based on a command from the control device 39 to carry the substrate A into the screen printer 12. Driven in the capturing direction (the direction of arrow a in FIG. 3).

  On the other hand, in step 108, in order to carry the substrate B into the screen printing machine 12, the second conveyor 35 on the second substrate loading position 18 side and the transport conveyor 33 of the substrate transport device 24 are in the substrate loading direction (arrow b in FIG. 3). Direction). In the following, the operation when the substrate A is carried into the screen printer 12 from the first substrate loading position 17 will be described.

  By driving the first conveyor 34 and the substrate transport device 24 in the substrate take-in direction, the substrate A is carried toward the printing work position of the screen printer 12. At this time, the position of the movable portion 40 of the robot 41 provided in the screen printer 12 is controlled, so that the substrate A comes into contact with the stopper 43 attached to the movable portion 40 and is positioned at the printing work position. 44. The printed board 11 carried into the printing work position is read by the camera 11 attached to the robot 41, and it is confirmed that the regular printed board 11 has been carried in.

  When the substrate A is positioned at the printing work position, the screen printing work by the screen printer 12 is started (step 110). That is, first, the substrate A is positioned and clamped to the substrate holding device 21, and then the substrate holding device lifting device 26 is driven to raise the substrate holding device 21. The substrate A held by the substrate holding device 21 is brought into contact with the lower surface of the screen mask 27 by the raising of the substrate holding device lifting device 26.

  Subsequently, cream solder is supplied and applied to the upper surface of the screen mask 27 by a cream solder supply device (not shown), and the squeegee head lifting / lowering device 32 lowers the squeegee head 30. Thereby, the squeegee head 30 is brought into contact with the screen mask 27, and in this state, the squeegee head moving device 31 moves the squeegee head 30 along the screen mask 27. At this time, the squeegee head 30 applies a predetermined load to the screen mask 27 in order to fill the pattern holes of the screen mask 27 with cream solder. In this way, predetermined screen printing is performed on the surface of the substrate A.

  When the predetermined printing operation on the substrate A by the screen printer 12 is completed, the determination result in step 112 is YES, and it is confirmed that the first substrate loading position 17 is empty (step 114), and then step 116 1, the first conveyor 34 and the transport conveyor 33 of the substrate transport device 24 are driven in the substrate payout direction (counter arrow a direction in FIG. 3), and the substrate A is transferred to the screen printing machine 12. Are carried out from the printing operation position toward the first substrate loading position 17. In other words, the substrate A that has been loaded into the screen printer 12 and completed the printing operation is transported and controlled by the first transport path T1 that is paid out to the loaded first substrate loading position 17 side. Note that if the next substrate A is accidentally loaded into the first substrate loading position 17 before the substrate A is carried out to the first substrate loading position 17, the determination result in step 114 is NO, In step 118, an abnormal signal is sent.

  When the substrate A that has completed the printing operation is discharged to the first substrate loading position 17, the operator M1 loads the substrate A from the first substrate loading position 17 to the unillustrated substrate loading position of the first mounting machine 13, The board A is carried into a mounting work position by a board transfer device (not shown) of the first mounting machine 13, and an electronic part mounting work is started.

  On the other hand, if the determination result in step 104 is YES, the process proceeds to step 108 where the second conveyor 35 at the second substrate loading position 18 and the transfer conveyor of the substrate transfer device 24 to carry the substrate B into the screen printer 12. 33 is driven in the substrate take-in direction (the direction of arrow b in FIG. 3), and screen printing is executed on the substrate B by the processing of Steps 120 to 126 similar to Steps 110 to 116 described above. Also in this case, the substrate B that has been carried into the screen printer 12 and completed the printing operation is transported and controlled by the second transport path T2 that is paid out to the loaded second substrate loading position 18 side.

  In this way, there are two board loading positions 17 and 18 into which the printed board 11 (A, B) is loaded, and the screen printing machine 12 prints the printed board 11 from these board loading positions 17 and 18 from different directions. A single screen printer 12 is transferred to a plurality of workers by delivering the printed circuit board 11 that has been loaded into the work position and printed by the screen printer 12 to the original substrate input positions 17 and 18 that have been input. It can be shared by M1 and M2. Thereby, while being able to suppress the increase in the installation cost for producing the printed circuit board 11, the occupation area of a production facility can be decreased. Further, by setting the cycle times of the printing machine 12 and the mounting machines 13 and 14 to approximately 1: 2, the waiting time (non-operation time) in the printing machine 12 and the mounting machines 13 and 14 is minimized. Is possible.

  FIG. 5 shows a second embodiment of the present invention. The difference from the first embodiment described above is that in the first embodiment, the first embodiment The first and second conveyors 34 and 35 for waiting the printed circuit board 11 loaded from the second board loading positions 17 and 18 are provided separately from the board transfer device 24, whereas the second embodiment In the embodiment, the first and second conveyors 34 and 35 are eliminated by using both sides 51 and 52 of the substrate transport device 24 (transport conveyor 33) as the first and second substrate loading positions 17 and 18. That is.

  That is, in the second embodiment, the transport conveyor 33 of the substrate transport device 24 is used as two conveyors for transporting the printed circuit board 11 from the first and second substrate loading positions 17 and 18 to the substrate transport device 24 of the printing press. Board lifting devices 53 and 54 for lifting the printed circuit board 11 waiting on both sides 51 and 52 of the conveyor 33 are provided below the sides 51 and 52 of the conveyor 33, respectively.

Even if the transport device 24 is operated, it is not carried into the printing work position of the screen printer 12.

  When the printed circuit board 11 that has completed the printing operation by the clean printing machine 12 is delivered to the one end side 51 (52) of the transport conveyor 33, the substrate lifting device 53 is lowered to the other end side 52 (51) of the transport conveyor 33. The printed circuit board 11 waiting on the above is placed on the transport conveyor 33 of the circuit board transport device 24. In this state, the circuit board transport device 24 is driven in the opposite direction (the other direction), so that the printed circuit board 11 is It is carried into the printing work position of the screen printer 12 and the printing work is started. Note that the same components as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
