The control device 40 controls the operation of a syringe operation mechanism 47 (FIG. 5) including an actuator (not shown).

  Next, an execution procedure of screen printing by the screen printer 1 will be described with reference to FIGS. The control device 40 detects that the substrate PB has been input from the operator (or another device (not shown) installed on the upstream side of the screen printing machine 1) to the substrate transport path 3 (loading conveyor 21) by a detection means (not shown). Then, the carry-in conveyor 21 and the positioning conveyor 22 are operated in conjunction to carry the substrate PB into the screen printer 1 (step ST1 in FIG. 6).

  When the control device 40 carries in the substrate PB, the control device 40 fixes the substrate PB to the substrate moving unit 31 (step ST2 in FIG. 6). For this, first, the second lifting plate 31f of the substrate moving unit 31 is raised relative to the first lifting plate 31e (arrow C1 shown in FIG. 7A), and the upper surface of the lower receiving unit 31g is placed on the substrate PB. The substrate PB is supported on the lower receiving unit 31g by contacting the lower surface (the lower surface of the carrier 13) from below (FIG. 7A). When the substrate PB is supported by the lower receiving unit 31g, the substrate PB is clamped by the clamper 31h, and then the second elevating plate 31f is further lifted (arrow C2 shown in FIG. 7B), and the lower receiving unit 31g. To push up the substrate PB. As a result, the substrate PB is lifted together with the carrier 13 while sliding both ends with respect to the clamper 31h, separated upward from the positioning conveyor 22, and the upper surface of the substrate PB is at the same height as the upper surfaces of both the clampers 31h. Thus, the substrate is fixed to the substrate moving unit 31 (FIG. 7B).

  When the fixing of the substrate PB is completed, the control device 40 aligns the rigid substrate 11 and the first mask region MR1 of the mask member 33 (step ST3 in FIG. 6).

  In this alignment, the control device 40 first performs the movement of the camera unit 36 and the imaging operation control of the first camera 36a to acquire image data of the rigid substrate alignment mark 11m provided on the rigid substrate 11, and the rigid substrate. 11, the camera unit 36 is moved and the imaging operation of the second camera 36 b is controlled to acquire image data of the mask member first alignment mark MK 1, and the first mask pattern MP 1 on the mask member 33 is acquired. Know the position of the.

  After grasping the position of the rigid substrate 11 and the position of the first mask pattern MP1 of the mask member 33, the control device 40 performs the movement operation of the substrate PB in the horizontal plane by the substrate moving unit 31 to move the substrate PB to the mask member 33. Then, the substrate moving unit 31 moves the substrate PB in the vertical direction (raises the first elevating plate 31e), after being positioned immediately below the first mask pattern MP1 (and therefore immediately below the first mask region MR1), The upper surface of the substrate PB is brought into contact with the lower surface of the mask member 33 from below (arrow C3 shown in FIG. 8A). As a result, the rigid substrate 11 and the first mask region MR1 of the mask member 33 are aligned, so that each electrode (rigid substrate electrode 11d) included in the rigid substrate 11 and each pattern hole h1 constituting the first mask pattern MP1 are positioned. (FIG. 8A).

When the alignment between the rigid substrate 11 and the first mask region MR1 of the mask member 33 is completed, the control device 40 performs screen printing on the rigid substrate 11 (step ST4 in FIG. 6).

  In screen printing on the rigid substrate 11, the control device 40 first moves the syringe unit 37 above the first mask region MR1, and supplies the paste PT from the syringe 37a to the upper surface of the mask member 33 (in the first mask region MR1). After that (FIG. 8A), one squeegee 34a is lowered and the lower edge of the squeegee 34a is brought into contact with the upper surface of the mask member 33. Then, the squeegee unit 34 is moved in the Y-axis direction, and the squeegee 34a is slid on the mask member 33 to scrape the paste PT (arrow C4 shown in FIG. 8B), and the paste PT is transferred to the first mask. The pattern hole h1 of the pattern MP1 is filled (FIG. 8B).

  FIG. 8 (b) shows a state in which the paste PT is scraped in the direction of the arrow C4 by moving the left squeegee 34a in the direction of the arrow C4. When squeezing in the opposite direction, the right squeegee 34a in the drawing is brought into contact with the upper surface of the mask member 33, and the squeegee unit 34 is moved in the direction opposite to the arrow C4.

  After filling the pattern hole h1 of the first mask pattern MP1 with the paste PT, the control device 40 lowers the first elevating plate 31e (arrow C5 shown in FIG. 9A), and the substrate PB and the mask member. 33 are separated (step ST5 in FIG. 6). As a result, the plate separation is performed, and the paste PT filled in the pattern hole h1 of the first mask pattern MP1 is printed (transferred) onto the rigid substrate electrode 11d (FIG. 9A).

  Thereby, the screen printing process (step ST3 to step ST5) for the rigid substrate 11 is completed, and the process proceeds to the screen printing process (step ST6 to step ST9) for the flex substrate 12 shown below.

  In screen printing on the flex substrate 12, the control device 40 first aligns the flex substrate 12 and the second mask region MR2 of the mask member 33 (step ST6 in FIG. 6).

  In this alignment, the control device 40 performs the movement of the camera unit 36 and the imaging operation control of the first camera 36a to acquire the image data of the flex substrate alignment mark 12m provided on the flex substrate 12, and the flex substrate 12 , And the image data of the mask member second alignment mark MK2 is obtained by moving the camera unit 36 and controlling the imaging operation of the second camera 36b, and obtaining the image data of the second mask pattern MP2 on the mask member 33. Know the location.

  After grasping the position of the flex substrate 12 and the position of the second mask pattern MP2 of the mask member 33, the control device 40 moves the substrate PB in the horizontal plane by the substrate moving unit 31 (in FIG. 9B). After the substrate PB is positioned immediately below the second mask pattern MP2 of the mask member 33 (and therefore directly below the second mask region MR2) (FIG. 9B), the substrate PB is moved by the substrate moving unit 31. The vertical movement of the first elevating plate 31e is performed to bring the upper surface of the substrate PB into contact with the lower surface of the mask member 33 from below (arrow C7 shown in FIG. 10A). As a result, the flex substrate 12 and the second mask region MR2 of the mask member 33 are aligned, so that each electrode (flex substrate electrode 12d) included in the flex substrate 12 and each pattern hole h2 constituting the second mask pattern MP2 are positioned. (FIG. 10A).

  When the alignment between the flex substrate 12 and the second mask region MR2 of the mask member 33 is completed, the control device 40 performs screen printing on the flex substrate 12 (step ST7 in FIG. 6).

  In screen printing on the flex substrate 12, the control device 40 first moves the syringe unit 37 above the second mask region MR2, and supplies the paste PT from the syringe 37a to the upper surface of the mask member 33 (in the second mask region MR2). After that (FIG. 10A), one squeegee 34a is lowered and the lower edge of the squeegee 34a is brought into contact with the upper surface of the mask member 33. Then, the squeegee unit 34 is moved in the Y-axis direction, and the squeegee 34a is slid on the mask member 33 to scrape the paste PT (arrow C8 shown in FIG. 10B), and the paste PT is transferred to the second mask. The pattern hole h2 of the pattern MP2 is filled (FIG. 10B).

  When filling the pattern hole h2 of the second mask pattern MP2 with the paste PT, the control device 40 lowers the first elevating plate 31e to separate the substrate PB and the mask member 33 (step ST8 in FIG. 6). As a result, the plate separation is performed, and the paste PT filled in the pattern hole h2 in the second mask pattern MP2 is printed on the flex substrate electrode 12d. Thereby, the screen printing on the flex substrate 12 is completed.

  When the screen printing on the flex substrate 12 is completed, the control device 40 opens the clamper 31h to release the substrate PB from being fixed to the substrate moving unit 31 (step ST9 in FIG. 6). Then, the second elevating plate 31f is lowered to place the substrate PB on the positioning conveyor 22, and the substrate moving unit 31 is operated to adjust the position of the positioning conveyor 22 relative to the carry-out conveyor 23. When the position adjustment of the positioning conveyor 22 with respect to the carry-out conveyor 23 is completed, the control device 40 operates the positioning conveyor 22 and the carry-out conveyor 23 in an interlocked manner to carry out the substrate PB from the screen printing machine 1 (step ST10 in FIG. 6).

  After carrying out the substrate PB, the control device 40 determines whether there is another substrate PB to be screen printed (step ST11 in FIG. 6). As a result, when there is another substrate PB to be screen-printed, the process returns to step ST1 to carry in the substrate PB, and when there is no substrate PB to be screen-printed, the series of screen printing steps is terminated.
