FIG. 9B shows a state in which the lifting table 22a is located at the lowered position P1 with respect to the base table 21d, and the lower receiving portion 24 is located at the raised position Q2 with respect to the lifting table 22a.

  Further, in FIG. 10A, the lower receiving portion 24 is located at the raised position Q2 with respect to the lifting table 22a, and the lifting table 22a is located at a position between the lowered position P1 and the raised position P2 with respect to the base table 21d. FIG. 10B shows a state in which the lower receiving portion 24 is positioned at the lift position Q2 with respect to the lift table 22a, and the lift table 22a is positioned at the lift position P2 with respect to the base table 21d. .

  In the screen printing machine 1 according to the present embodiment, in the operation procedure, the lower receiving part 24 moves up and down only when the lifting table 22a is located at the lowered position P1 with respect to the base table 21d. Therefore, when the elevating table 22a moves up and down with respect to the base table 21d, the lower receiving portion 24 is always in a state of being in the ascending position Q2 with respect to the elevating table 22a.

  As shown in FIG. 8A, the lift table 22a is located at the lowered position P1 with respect to the base table 21d, and the lower receiving portion 24 is located at the lowered position Q1 with respect to the lift table 22a (this state is referred to as a standby state). ), The lower receiving portion 24 (the lower receiving unit support table 24a) is not in contact with the downwardly extending portion 34 of the substrate end portion supporting member 25, and the substrate end portion supporting member 25 is lowered by its own weight. 33d is in contact with the stopper 31f of the belt conveyor support member 31 from above. In this standby state, the upper end surface 33c of the main body portion 33 of the substrate end portion support member 25 (and hence the upstream vertical end surface 33a of the main body portion 33 of the substrate end portion support member 25) is transferred from the substrate carry-in conveyor 13 (that is, the substrate transfer). It is located below the transfer surface S of the substrate 2 entering the conveyor portion 23 of the substrate holding and moving unit 12 (from the upstream side of the path 39), and the conveyor portion 23 receives the substrate 2 carried in by the substrate carry-in conveyor 13 Can do.

  Next, the operation procedure of the screen printing machine 1 will be described with reference to the flowchart of FIG. 11 and the explanatory diagrams of FIGS. The control device 50 of the screen printing machine 1 puts the substrate holding and moving unit 12 in the standby state as described above, and other devices and the like installed on the upstream side of the screen printing machine 1 by a detection unit (not shown) (see FIG. When it is detected that the substrate 2 is loaded into the substrate carry-in conveyor 13 from the substrate carry-in conveyor 13, the substrate carry-in conveyor 13 and the conveyor unit 23 are operated in conjunction to carry the substrate 2 into the screen printer 1 (FIG. 12A). In addition, when the detection unit (not shown) detects that the substrate 2 loaded into the conveyor unit 23 has reached a predetermined conveyance stop position, the operation of the conveyor unit 23 is stopped, and the substrate 2 is Still (FIG. 12B, FIG. 13A and FIG. 8A. Substrate loading step shown in step ST1 of FIG. 11).

  When the substrate carrying-in process is completed, the control device 50 closes the front and rear clamping members 26a to clamp (hold) the substrate 2 on the conveyor unit 23 from the Y-axis direction (FIG. 13B). Arrow B1) shown in the inside. Then, the lower receiving portion 24 is raised from the lowered position Q1 with respect to the lifting table 22a while the lifting table 22a is positioned at the lowered position P1 with respect to the base table 21d (arrows shown in FIGS. 13 (c) and 14 (a)). C1). Then, the lower receiving portion 24 (lower receiving unit support table 24a) comes into contact with the lower extending portions 34 of the front and rear substrate end supporting members 25 from below (FIGS. 13C and 8B), and the lower The upper end of the receiving portion 24 and the upper end surface 33c of each of the front and rear substrate end support members 25 have the same height.

  After the lower receiving portion 24 comes into contact with the downwardly extending portions 34 of the front and rear substrate end support members 25 from below, when the lower receiving portion 24 is further raised with respect to the lifting table 22a, the front and rear substrate end supporting members 25 is pushed up by the lower receiving portion 24 and is raised with respect to the front and rear belt conveyor support members 31 together with the lower receiving portion 24. When the lower receiving portion 24 is further raised with respect to the lifting table 22a, the upper end of the lower receiving portion 24 is on the lower surface of the central portion of the substrate 2 supported at both ends by the front and rear belt conveyors 32, and the front and rear substrate ends. The upper end surface 33c of the part support member 25 abuts on both ends of the lower surface of the substrate 2 from below (FIGS. 14A and 9A).

  The control device 50 is configured such that the upper end of the lower receiving portion 24 comes into contact with the center portion of the substrate 2, and the lower receiving portion 24 reaches a height at which the upper end surfaces 33 c of the front and rear substrate end supporting members 25 come into contact with both end portions of the substrate 2. When it rises, the raising operation of the lower receiving portion 24 is temporarily stopped. Then, the operation of the conveyor separation proximity motor 35 is controlled to move the front and rear belt conveyor support members 31 in directions away from each other (arrow D1 shown in FIG. 14B), and the front and rear belt conveyors 32 are moved to the substrate 2. The front and rear substrate end support members 25 are moved to the portions where the front and rear belt conveyors 32 have supported the substrate 2 so that both ends of the substrate 2 support the front and rear substrate ends. It is made to be supported only by the member 25 (FIG.14 (b). Belt conveyor support member separation process).

  When the belt conveyor support member separation step is finished, the control device 50 raises the lower support portion 24 (arrow C2 shown in FIG. 14C), and the lower support portion 24 and the front and rear substrate end support members 25 The substrate 2 is pushed up until the upper surface of the substrate 2 becomes the same height as the upper surfaces of the front and rear clamp members 26a. At this time, the lower receiving part 24 will be in the state raised to the raising position Q2 with respect to the raising / lowering table 22a. As a result, the substrate 2 is lifted while sliding both ends thereof with respect to the front and rear clamp members 26a, and both ends are separated upward from the front and rear belt conveyors 32. It will be in the state lifted and supported by the edge part supporting member 25 (FIG.14 (c) and FIG.9 (b). The board | substrate support process shown by step ST2 of FIG. 11).

  FIG. 9B shows a state in which the substrate support process is completed (the lifting table 22a is located at the lowered position P1 with respect to the base table 21d and the lower receiving unit 24b is located at the raised position Q2 with respect to the lifting table 22a). As shown in FIG. 4, the substrate is brought into contact with the substrate 2 entering the conveyor portion 23 of the substrate holding / moving unit 12 from the substrate carry-in conveyor 13 (that is, from the upstream side of the substrate transport path 39) (position that crosses the transport surface S up and down). The substrate end support member 25 is located. For this reason, after the substrate support process is completed, while the lift table 22a is positioned at the lowered position P1 with respect to the base table 21d and the lower receiving portion 24 is positioned at the lift position Q2 with respect to the lift table 22a, an error occurs. Thus, it is possible to prevent the substrate 2 from entering the conveyor portion 23 of the substrate holding and moving unit 12 from the substrate carry-in conveyor 13 (that is, from the upstream side of the substrate conveyance path 39).

  When the substrate support process is completed, the control device 50 controls the operation of the camera unit moving mechanism 55 (moves the X axis stage 45 in the Y axis direction and moves the camera support stage 46 in the X axis direction). The first camera 17a is positioned immediately above the substrate-side positioning mark mk provided on the substrate 2, and the first camera 17a is imaged of the substrate-side positioning mark mk to detect the position of the substrate 2 ( Fig. 15 (a): Substrate position detection step shown in step ST3 of Fig. 11) Next, the second camera 17b is positioned directly below the mask side positioning mark MK provided on the mask 15, and the second camera 17b is masked. The position of the mask 15 is detected by imaging the side positioning mark MK (FIG. 15B) (mask position detection step shown in step ST4 of FIG. 11).

  When the above-described mask position detection step is completed, the control device 50 performs the operation control of the horizontal moving unit 21 included in the substrate holding and moving unit 12 to move the substrate holding unit 26 (and thus the substrate 2) in the horizontal plane direction. The substrate 2 is positioned in the horizontal plane with respect to the mask 15 so that the substrate-side positioning mark mk and the mask-side positioning mark MK face each other vertically (positioning step shown in step ST5 in FIG. 11).

  In this positioning step, the control device 50 positions the substrate 2 with respect to the mask 15 so that the substrate-side positioning mark mk and the mask-side positioning mark MK are aligned vertically.

  When the positioning step is completed, the control device 50 raises the lifting table 22a with respect to the base table 21d (arrow E1 shown in FIG. 15C), and supports the conveyor unit 23 and the substrate 2 from below. The upper surface of the substrate 2 is brought into contact with the lower surface of the mask 15 by raising the lower support portion 24 integrally (FIGS. 15C and 10B), as shown in step ST6 of FIG. Contact process). At this time, the elevating table 22a is raised to the ascending position P2 with respect to the base table 21d, and the substrate 2 comes into contact with the mask 15 from the lower surface and is located at a predetermined position where the paste Pst is transferred by the squeegee 16. As a result, the electrode 3 of the substrate 2 and the pattern hole 15a of the mask 15 are aligned vertically.

  FIG. 10B shows a state where the contact process is completed (the lower receiving portion 24 is positioned at the rising position Q2 with respect to the lifting table 22a and the lifting table 22a is positioned at the lifting position P2 with respect to the base table 21d). As shown, the board entry restricting member 40 provided on the belt conveyor support member 31 is in contact with the board 2 entering the conveyor unit 23 of the board holding and moving unit 12 from the upstream side of the board carrying path 39 (the carrying surface S). Is located across the top and bottom). Therefore, while the paste Pst is transferred by the squeegee 16 after the contact step, the substrate 2 is mistakenly transferred from the substrate carry-in conveyor 13 (that is, from the upstream side of the substrate transfer path 39) of the substrate holding and moving unit 12. It can prevent entering the conveyor part 23. FIG.

  When the above-described contact process is completed, the control device 50 temporarily interrupts the operation of the screen printing machine 1 and then displays an image via the display device 57 (FIG. 7) provided on the base 11 to the operator OP. Prompt the supply of the paste Pst. The operator OP visually checks the paste Pst remaining on the mask 15, determines whether or not to supply (replenish) the paste Pst based on the amount of the paste Pst, and supply the paste Pst. If it is determined, the paste Pst is supplied onto the mask 15 by using a separately provided paste supply syringe 60 (FIG. 16A). When the supply of the paste Pst is finished, the operation restart button 58 (FIG. 7) provided on the base 11 is operated. The operator OP operates the operation restart button 58 even when it is determined that the supply of the paste Pst is unnecessary.

  After the contact step, the control device 50 determines whether or not the operation restart button 58 has been operated by the operator OP based on the output of the operation signal from the operation restart button 58 (shown in step ST7 of FIG. 11). Judgment process). When the control device 50 determines that the operation restart button 58 has been operated by the operator OP, the control device 50 cancels the operation interruption of the screen printing machine 1, lowers one of the two squeegees 16 and touches the upper surface of the mask 15. The squeegee 16 is slid on the mask 15 by moving the squeegee base 47 in the Y-axis direction (arrow F shown in FIG. 16B), and the substrate 2 is formed through the pattern hole 15a of the mask 15. The paste Pst is transferred to the electrode 3 (paste transfer process shown in step ST8 of FIG. 11). Then, when the sliding of the squeegee 16 is finished, the control device 50 raises the squeegee 16 abutted on the mask 15 and separates it from the upper surface of the mask 15.

  Here, the front squeegee 16 (the squeegee 16 on the left side in FIG. 16) is rearward on the mask 15 from the upper surface area of the front clamp member 26a to the upper surface area of the rear clamp member 26a (on the right side in FIG. 16). The rear squeegee 16 (the squeegee 16 on the right side in FIG. 16) is moved on the mask 15 from the upper surface area of the rear clamp member 26a to the upper surface area of the front clamp member 26a. It is moved forward (left side in FIG. 16, the direction opposite to the arrow F).

  When the paste transfer process is completed, the control device 50 lowers the lifting table 22a with respect to the base table 21d (arrow E2 shown in FIG. 17A), and separates the substrate 2 from the mask 15 to release the plate. (FIG. 17A. Plate separation process shown in step ST9 of FIG. 11). As a result, the paste Pst is printed on the electrode 3 of the substrate 2.

  After performing the above-described plate separation process, the control device 50 controls the operation of the conveyor separation proximity motor 35 to move the front and rear belt conveyor support members 31 in directions close to each other (shown in FIG. 17B). Arrow D2), the front and rear belt conveyors 32 are positioned directly below both ends of the substrate 2 (FIG. 17B).

  When the front and rear belt conveyors 32 are positioned immediately below both ends of the substrate 2, the control device 50 opens the clamp member 26a (arrow B2 shown in FIG. 17C) to clamp the substrate 2. Is released so that the substrate 2 is supported by the lower receiving portion 24 and the front and rear substrate end supporting members 25, and then the lower receiving portion 24 is lowered with respect to the lifting table 22a (FIG. 18A). (B), arrow C3 shown in (c). Then, first, both end portions of the substrate 2 are placed on the front and rear belt conveyors 32 (FIG. 18A), and then the upper end of the lower receiving portion 24 and the upper end surface 33 c of the front and rear substrate end support members 25 are formed on the substrate 2. It is spaced downward from the lower surface (FIG. 18B). When the elevating table 22a is further lowered, the lower end surfaces 33d of the front and rear substrate end supporting members 25 are brought into contact with the stopper 31f of the belt conveyor supporting member 31 from above, and further descending is restricted. In the state where the table 21d is in the lowered position Q1, the front and rear substrate end support members 25 are separated from the upper surface of the lift table 22a (FIG. 18C). Thereby, the support of the substrate 2 by the substrate holding part 26 is released (substrate support releasing step shown in step ST10 of FIG. 11).

  When the support of the substrate 2 is released, the control device 50 operates the horizontal moving unit 21 provided in the substrate holding and moving unit 12 to adjust the position of the conveyor unit 23 with respect to the substrate carry-out conveyor 13, and then the conveyor unit 23 and the substrate The carry-out conveyor 14 is operated in conjunction to transfer the substrate 2 on the conveyor unit 23 to the substrate carry-out conveyor 14 and carry the substrate 2 out of the screen printing machine 1 as it is (substrate carry-out process shown in step ST11 in FIG. 11).

  After unloading the substrate 2, the control device 50 determines whether there is another substrate 2 on which screen printing is to be performed (determination step shown in step ST12 of FIG. 11). As a result, if there is another substrate 2 to be screen-printed, the process returns to step ST1 to carry in a new substrate 2, and if there is no other substrate 2 to be screen-printed, a series of screen printing operations.
