An anti-slip plate 16 is fixedly mounted at the discharge end of the slide rail 141, and an anti-collision member 15 is installed at the other end of the slide rail 141. The anti-slip plate 16 is used to position the workbench 2 when the slider 142 moves to the discharge end to prevent the workbench 2 from detaching from the machine body 1. The anti-collision member 15 includes a fixed plate 151 fixedly mounted on the end of the slide rail 141 away from the anti-slip plate 16, an anti-collision spring 152 fixedly mounted on the side of the fixed plate 151 facing the anti-slip plate 16, and a buffer plate 153 fixedly mounted on the end of the anti-collision spring 152.

Similarly, an elastic pad 2 19 is fixed to the side of the anti-slip plate 16 that contacts the workbench 2.

[0035] Reference Figure 3 and Figure 4 When the workbench 2 moves close to the anti-collision member 15, in order to ensure the stability of the workbench 2, a limit member 17 is installed on the machine body 1. The limit member 17 is located at one end of the workbench 2 close to the anti-slip plate 16. The limit member 17 is mainly used to position the workbench 2 to prevent the workbench 2 from slipping during processing. The limit member 17 includes a limit motor 172 fixedly mounted on the machine body 1 and a limit plate 171 fixed to the piston end of the limit motor 172. A recovery groove 20 for rotating and positioning the limit plate 171 is provided on the top surface of the machine body 1. The limit motor 172 drives the limit plate 171 to rotate out of the recovery groove 20 and position the side wall of the workbench 2, thereby improving the stability of the workbench 2 during processing.

[0036] Reference Figure 3After the workbench 2 is positioned, the positioning device 5 positions the side of the circuit board. The positioning device 5 includes positioning plates 1 51 located on both sides of the workbench 2 in the length direction, positioning plates 2 52 located on both sides of the workbench 2 in the width direction, and driving cylinders 1 53 and 2 54 fixedly installed in the workbench 2. The piston end of driving cylinder 1 53 is fixedly connected to positioning plate 1 51. The top surface of the workbench 2 is provided with a groove for the connection between positioning plate 1 51 and driving cylinder 1 53 to move, so that driving cylinder 1 53 can drive positioning plate 1 51 to move along the width direction of the workbench 2. The piston end of driving cylinder 2 54 is fixedly connected to positioning plate 2 52. The top surface of the workbench 2 is provided with a groove for the connection between positioning plate 2 52 and driving cylinder 2 54 to move, so that driving cylinder 2 54 can drive positioning plate 2 52 to move along the length direction of the workbench 2. Positioning plates 1 51 and 2 52 can position the circuit board according to its size, improving the practicality of the printing press.

[0037] Reference Figure 3 and Figure 5 After the positioning device 5 positions the circuit board, the limiting device 4 positions the positioning hole of the circuit board to improve the stability of the circuit board during processing. The limiting device 4 includes a moving block 41 installed at the corner of the top surface of the workbench 2, a limiting block 42 installed on the moving block 41 and used to be inserted into the positioning hole, and a moving assembly 43 installed on the workbench 2 and used to drive the moving block 41 to move to the bottom of the positioning hole. The moving assembly 43 includes a moving motor 432 fixedly installed on the workbench 2 and a bidirectional screw 431 fixedly installed at the output end of the moving motor 432. The moving block 41 is threadedly connected to the bidirectional screw 431. A moving groove 7 for installing the bidirectional screw 431 is provided on the top surface of the workbench 2. The moving groove 7 of the present application is set along the diagonal line to facilitate the synchronous movement of the moving blocks 41 at both ends. The top surface of the moving block 41 is provided with an embedding groove 9 for the limiting block 42 to be embedded. The bottom end of the limiting block 42 is fixedly mounted with a rotating shaft 8 located in the embedding groove 9 . The moving block 41 is rotatably connected to the limiting block 42 via the rotating shaft 8 .

[0038] Reference Figure 5When the limit block 42 moves to the position of the circuit board, the circuit board pushes the limit block 42 to rotate toward the embedding groove 9. In order to improve the rotation stability of the limit block 42 and facilitate the rotation and reset of the limit block 42 into the positioning hole, a telescopic rod 10 is installed on the side of the limit block 42 away from the circuit board. The telescopic rod 10 is sleeved with a limit spring 11. The telescopic rod 10 is arc-shaped and the center of the arc is consistent with the rotation axis of the limit block 42. One end of the limit spring 11 is fixed to the limit block 42, and the other end of the limit spring 11 is fixed to the moving block 41. The telescopic rod 10 includes an outer tube 101 fixedly mounted on the limit block 42 and an inner tube 102 fixedly mounted on the moving block 41. The inner tube 102 is located below the embedding groove 9. The moving block 41 is provided with a placement groove 12 that is connected to the embedding groove 9 and is used for the outer tube 101 to be sleeved on the outside of the inner tube 102. The inner tube 102 is located below the insertion groove 9. After the outer tube 101 is sleeved on the inner tube 102, the limit block 42 can directly enter the insertion groove 9, preventing the outer tube 101 from obstructing the limit block 42 from entering the insertion groove 9. The top surface of the movable block 41 is aligned with the level of the workbench 2 to ensure the flatness of the workbench 2. When the limit block 42 enters the insertion groove 9, the top surface of the limit block 42 is less than or equal to the top surface of the movable block 41.

[0039] Reference Figure 2 When the circuit board processing is completed, the jacking device 6 is started to jack up the circuit board to facilitate the staff to take the circuit board. The jacking device 6 includes a jacking cylinder 62 fixedly installed in the workbench 2 and a jacking plate 61 fixedly installed at the piston end of the jacking cylinder 62. The top surface of the workbench 2 is provided with a groove 13 for placing the jacking plate 61. The groove 13 is used to ensure that when the jacking plate 61 is located in the groove 13, the top surface level of the jacking plate 61 is consistent with the top surface level of the workbench 2, which facilitates the placement of the circuit board on the workbench 2.

[0040] The implementation principle of an ink printing machine according to an embodiment of the present application is as follows: first, the workbench 2 is moved to the side of the machine body 1 by means of the slider 142 and the slide rail 141, so that the staff can place the circuit board on the workbench 2; then the workbench 2 is pushed back to its original position, the limit motor 172 is started, and the limit plate 171 is driven to position the side of the workbench 2, and the limit plate 171 cooperates with the buffer plate 153 to position the workbench 2. Then the positioning device 5 is started, and the side of the circuit board is positioned using the positioning plate 1 51 and the positioning plate 2 52. After the positioning device 5 is positioned, the moving motor 432 is started to drive the moving block 41 to move toward the corner of the circuit board. After the limit block 42 is moved into the positioning hole, the circuit board is positioned to improve the stability of the circuit board during processing. Then the ink coating device 3 processes the circuit board. After the processed circuit board is finished, the limit motor 172 needs to be started to retract the limit plate 171, and then the workbench 2 is moved to the side of the machine body 1. The lifting cylinder 62 is started, and the lifting plate 61 lifts the circuit board to facilitate the staff to take the circuit board. This application can position circuit boards of different sizes, making it easier for staff to take the circuit board.
