  • the control device 40 When the holding of the board 2 by the board holding mechanism 13 is completed, the control device 40 operates the camera moving mechanism 19K to position the camera 19 between the board 2 held by the board holding mechanism 13 and the mask plate 16. Then, the control device 40 causes the camera 19 to take an image of the substrate mark (not shown) provided on the substrate 2 and the mask mark (not shown) provided on the mask plate 16. When the camera 19 captures the substrate mark and the mask mark, the control device 40 grasps the position of the substrate 2 with respect to the mask plate 16 based on the image data of these marks.
  • the control device 40 Upon grasping the position of the substrate 2 with respect to the mask plate 16, the control device 40 controls the stage 12 to move the substrate 2 in the horizontal plane. Then, the substrate 2 is aligned in the horizontal plane so that the substrate mark and the mask mark face each other vertically. By this alignment, the substrate 2 is aligned with the mask plate 16. Then, when the alignment of the substrate 2 is completed, the control device 40 operates the stage 12 as shown by the arrow H in FIG. 20A to raise the entire substrate holding mechanism 13. As a result, as shown in FIG. 20B, the control device 40 brings the upper surface of the substrate 2 into contact with the lower surface of the mask plate 16 from below. As a result, the pattern hole 16H of the mask plate 16 and the electrode pattern 2D on the substrate 2 match.
  • the control device 40 lowers one of the squeegees 18 and brings the lower edge of the lowered squeegee 18 into contact with the upper surface of the mask plate 16. Then, as shown by an arrow G in FIG. 20B, the squeegee 18 in contact with the mask plate 16 is moved along the Y axis, and the paste Pst is scraped by the squeegee 18. By this operation, the paste Pst is filled in the pattern hole 16H of the mask plate 16.
  • the paste Pst When the paste Pst is filled in the pattern hole 16H of the mask plate 16, the paste Pst is printed on the electrode pattern 2D of the substrate 2. After that, the control device 40 operates the stage 12 to lower the entire substrate holding mechanism 13, separates the substrate 2 from the mask plate 16, and releases the plates.
  • the control device 40 When the plate release is completed, the control device 40 operates the clamp cylinder 26 and moves the side clampers 25 in the directions away from each other to release the clamp of the substrate 2. Then, the control device 40 lowers the lower receiving unit 21 with respect to the moving stage 12e to lower the substrate 2 onto the intermediate conveyor 24. Further, the control device 40 operates the intermediate conveyor 24 and the unloading conveyor 15 to deliver the substrate 2 on the intermediate conveyor 24 to the unloading conveyor 15. When the unloading conveyor 15 receives the substrate 2 from the intermediate conveyor 24, the unloading conveyor 15 carries out the substrate 2 to the outside of the screen printing machine 1.
  • the storage space 25S of the top clamper 27 is recessed (opened to the upper surface) from the upper surface of the side clamper 25. Therefore, the movement path when moving the top clamper 27 from the storage position to the overhanging position and from the overhanging position to the storage position is extremely short. Therefore, the top clamper 27 can be moved in a compact configuration, and the size of the screen printing machine 1 can be suppressed.
  • the present disclosure is not limited to the above-mentioned ones, and various modifications and the like are possible.
  • the top clampers 27 are each stored in the storage space 25S.
  • the thickness (dimension along the Z axis) of the top clamper 27 is extremely small, the substrate 2 is brought into contact with the mask plate 16 without storing the top clamper 27 in the storage space 25S, and screen printing is performed. You may want to do it.
  • the storage space 25S is provided so as to open on the upper surface of the side clamper 25. More specifically, in the example shown in FIG.
  • the storage space 25S is rectangular and penetrates the side clamper 25 in a size that can accommodate the top clamper 27. However, if the top clamper 27 can be stored, it does not have to penetrate except for the portion through which the end extension portion 27B and the center extension portion 27R are inserted. In particular, when the thickness of the top clamper 27 is extremely small, the upper surface of the side clamper 25 may be used as the storage space 25S. That is, the storage space 25S does not necessarily have to be recessed from the upper surface of the side clamper 25. As described above, the storage space 25S may be provided on the upper surface side of the side clamper 25.
  • top clamper moving mechanism 28 described above is only an example. If the top clamper 27 can be stored in the storage space 25S provided on the upper surface side of the side clamper 25, and if the top clamper 27 can be moved from the storage space 25S to the overhanging position, even if it has other configurations. I do not care.
  • the top clamper can be moved in a compact configuration, and it is possible to prevent the device from becoming large as a whole. Therefore, the work holding device and the screen printing machine are industrially useful from the viewpoint of space saving.
