Embodiment Construction

[0060] The main purpose of the present invention is to provide a screen printing mold and a screen printing machine which can improve the printing quality and efficiency of the convex surface of the arched workpiece.

[0061] Please refer to Figure 1-Figure 4 In order to realize the industrial printing of the convex surface of the arched workpiece 100, a corresponding screen printing machine can be provided. The convex surface of the arched workpiece includes a first plane, a second plane, and a curved surface that is smoothly connected with the first plane and the second plane respectively; The screen printing machine includes a screen printing mold 200, a frame 300, a scraper mechanism 400, a screen printing screen 500 and a plurality of driving mechanisms for driving movable parts to move.

[0062] In this screen printer, please refer further to Figure 5 , the top of the screen printing mold 200 forms a first mold cavity 21 and a second mold cavity 22 along the X axis, a...

Abstract

The invention discloses a silk-screen printing die and a silk-screen printing machine. A first die cavity and a second die cavity are respectively formed at the top of the silk-screen printing die along an X axis; a clearance part and / or a bending die cavity corresponding to the curved surface part of an arched workpiece are / is formed at the joint of the first die cavity and the second die cavity;the silk-screen printing die is provided with a pin-jointed structure, the rotation axis of the pin-jointed structure is parallel to a Y axis, and the rotation axis is adjacent to the clearance partand / or the bending die cavity; vacuumizing holes are formed in both the bottom surface of the first die cavity and the bottom surface of the second die cavity; the silk-screen printing die further comprises suction nozzle pieces fixedly installed in the vacuumizing holes, each suction nozzle piece comprises a pipe body and a flexible suction nozzle arranged at the upper end of the pipe body, and an opening at the upper end of each flexible suction nozzle protrudes out of the bottom surface of the corresponding first die cavity and the bottom surface of the corresponding second die cavity. TheY axis, the X axis, and a Z axis corresponding to the vertical direction are perpendicular two by two. According to the silk-screen printing die in the invention, the workpiece can be accurately fixed, the pressure of a scraper of a scraper mechanism is stable, and the convex surface printing efficiency and quality of the arched workpiece are improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a screen printing mold and a screen printing machine. Background technique [0002] Screen printing belongs to stencil printing, and its working principle is: first make a printing plate with holes through which ink can pass, and then transfer the ink to the substrate through the holes of the stencil through a certain pressure during printing. The screen printing process is highly adaptable and can adapt to various substrates with different materials and surface shapes. Commonly used in these applications is the printing of flat and simple circumferential surfaces, but for the printing of the convex surface of the arched workpiece, there are generally two solutions proposed in the prior art: one is to make a curved screen, and the scraper adapts to the curved motion of the screen. ; The second is to split the arched workpiece into sub-components with simple surfaces, ...
