Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0016] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution for a vacuum screen printing machine: its structure includes a vacuum screen printing machine base 1, a column 2, a transmission beam 3, and a magnetic repulsion screen printing plate fixing frame 4; the column 2 is vertically arranged at the rear of the top surface of the vacuum screen printing machine base 1; the transmission beam 3 is slidably arranged on the front end face of the column 2; the magnetic repulsion screen printing plate fixing frame 4 has a U-shaped structure, and its two inner sides of the opening are respectively fixedly connected to the outer walls of the left and right sides of the transmission beam 3; the printing assembly 5 is horizontally slidably arranged on the front end face of the transmission beam 3. like Figure 2 As shown, the magnetic repulsion screen printing plate fixing frame 4 includes two longitudinal positioning rods 41 spaced apart and a transverse positioning rod 42 located directly in front of the two longitudinal positioning rods 41. The front ends of the two longitudinal positioning rods 41 are provided with telescopic slots 43. The rear ends of the transverse positioning rods 42 are provided with telescopic rods 44 on the left and right sides, which are respectively movably embedded in the two telescopic slots 43. The rear ends of the telescopic rods 44 are detachably connected to magnetic sheets 441. The inner wall of the rear end of the telescopic slots 43 is provided with electromagnets 45 that generate repulsive force against the magnetic sheets 441. The top surface of the front part of the telescopic rods 44 is provided with a spring positioning groove 46. A return spring 47 is fixedly installed in the spring positioning groove 46. The other end of the return spring 47 is connected to the top surface of the inner wall of the telescopic slots 43. It also includes a screen printing plate 7 installed on a magnetic repulsion screen printing plate fixing frame 4.

[0017] The detachable type can be a snap-fit ​​connection or a bolt connection, with bolt connection being preferred to ensure the connection is secure.

[0018] To improve assembly stability, screen printing plate positioning grooves 48 are provided on the opposite end faces of the two longitudinal positioning rods 41 and the rear end face of the transverse positioning rod 42.

[0019] like Figure 3 As shown, for preliminary assembly, the screen printing stencil 7 is set horizontally, with its front end and both sides respectively fitted into the corresponding screen printing stencil positioning grooves 48.

[0020] The outer side of the screen printing stencil 7 is made of rubber to facilitate its elastic insertion into the positioning groove 48 of the screen printing stencil.

[0021] In order for the electromagnet 45 to operate normally, the outer wall of the longitudinal positioning rod 41 is connected to a conductive wire that supplies power to the electromagnet 45.

[0022] For ease of operation, a control panel 6 for controlling the operation of the printing components 5 and the electromagnet 45 is provided at the front end of the vacuum screen printing machine base 1.

[0023] For printing operations, the printing assembly 5 includes a squeegee and a drive cylinder for driving the squeegee to move vertically.

[0024] In order to firmly adsorb and position the workpiece and ensure stable printing, the front of the top of the vacuum screen printing machine base 1 is provided with a groove-shaped workpiece printing platform with micro-holes, and the vacuum screen printing machine base 1 is equipped with a vacuum pump for sucking air from the workpiece printing platform plane.

[0025] Principle: When assembling the screen printing stencil 7, first operate the control panel 6 to make the electromagnet 45 rotate. The electromagnet 45 generates a repulsive force on the magnetic sheet 441, causing the magnetic sheet 441 to drive the telescopic rod 44 to slide towards the front end of the telescopic slot 43. The telescopic rod 44 drives the transverse positioning rod 42 away from the transverse positioning rod 42, making it easier to insert the screen printing stencil 7. While the telescopic rod 44 is sliding, the return spring 47 will be stretched. Then, the screen printing stencil 7 is installed between the two longitudinal positioning rods 41. As the electromagnet 45 is de-energized, the return spring 47 is released from its restriction, causing the telescopic rod 44 to return to its original position. The telescopic rod 44 drives the transverse positioning rod 42 to cooperate with the screen printing stencil positioning slot 48 to clamp and fix the screen printing stencil 7. The operation is simple. Example 2
