AI Technical Summary
The rolling countertops of existing screen printing machines have shortcomings in terms of transmission accuracy, reuse rate and cost control, especially the turntable structure and linear motor cross-brush platform structure are poor in the face of paper thickness changes and dirt, resulting in difficult maintenance and high cost.
It adopts a one-way belt conveying printing mechanism, including motors, transmission printing belts, base plates and printing adsorption tabletops, and uses a motor-driven belt to convey silicon wafers. The belt is made of Teflon, stainless steel or white cardboard materials, and has a self-tensioning function. It replaces traditional glass tabletops to achieve accurate transmission and efficient reuse.
Improves transmission in place accuracy, increases reuse rate, reduces production costs, and simplifies maintenance processes, suitable for silicon wafer transfers of various materials.

Description
Technical Field
[0001] The utility model relates to a unidirectional belt transmission printing mechanism of a screen printing machine, belonging to the technical field of screen printing machines. Background Art
[0002] In the prior art, screen printing mainly adopts the following two methods: one is to be conveyed by a standard conveyor to a turntable structure driven by a DD motor, and the transplanting to the printing station is realized by rotating the turntable by a certain angle; the other is to be conveyed by a standard conveyor to a linear motor cross-printing platform, and the printing platform is driven by the linear motor to the printing station.
[0003] The printing table of the turntable structure relies on the motor to pull the winding paper to realize the transmission of the silicon wafer. Due to the change in the thickness of the winding paper and the amplitude of the swing, the accuracy of the transmission in place and the reuse after being soiled cannot be guaranteed. Moreover, this structure requires a special winding paper motor, with high costs and high damage and maintenance costs.
[0004] For the linear motor cross-hard brush platform structure, the winding paper on the printing platform of the printing platform is easily affected by the soiling of the burst net and cannot be reused, with poor timeliness, frequent replacement of the winding paper, and troublesome and time-consuming disassembly and replacement.
[0005] Neither of the above two methods can well solve the problems such as the accuracy of the winding paper table in place, the efficiency of reuse, cost control, and the improvement of the overall line operation rate. Summary of the Utility Model
[0006] The unidirectional belt transmission printing mechanism of a screen printing machine proposed by the utility model aims to overcome the above-mentioned deficiencies existing in the prior art, improve the transmission accuracy in place, realize reuse, reduce costs, and simplify maintenance.
[0007] The technical solution of the utility model: A unidirectional belt transmission printing mechanism of a screen printing machine, the structure of which includes a motor, a transmission printing belt, a bottom plate and a printing adsorption table. The motor is installed at one end of the bottom plate, the output end of the motor is connected to one end of the driving wheel roller shaft through a transmission mechanism, the driving wheel roller shaft is rotatably connected to one end of the printing adsorption table, the other end of the printing adsorption table is rotatably connected to the driven wheel roller shaft, a transmission printing belt is sleeved between the driving wheel roller shaft and the driven wheel roller shaft, the transmission printing belt is located outside the printing adsorption table, and a tensioning mechanism is arranged on the side of the driven wheel roller shaft, and the tensioning mechanism is connected to the printing adsorption table and the side of the bottom plate.
[0008] Preferably, the transmission printing belt is a Teflon belt, a stainless steel belt or a white card paper belt.
[0009] Advantages of the present utility model: The structure design is simple and reasonable. The printing structure with a one-way belt transmission is used to replace the glass tabletop, which can be compatible with various materials such as Teflon, stainless steel belt, white cardboard, etc., and can be compatible with printing the whole piece and half piece. During the process of transporting and conveying silicon wafers, the belt does not shift, the positioning is accurate, it has a self-tensioning function, a high reuse rate, convenient replacement and maintenance, time-saving and labor-saving, and can save production costs.
