Transfer device and screen printing machine with same

Abstract

The invention discloses a transfer device and a screen printing machine with the same. The transfer device is used for adjusting the spatial position of a screen printing platform, and comprises a base which is provided with a first inclined plane which is arranged upwards; a bearing which is provided with a second inclined plane arranged downwards, and the top of which is provided with the silk-screen printing platform; a first sliding mechanism, which comprises a fixed part and a movable part, wherein the fixed part is fixedly connected with the first inclined plane, the extending directionof the fixed part is parallel to the first inclined plane and intersects with the horizontal plane, the movable part is fixedly connected with the second inclined plane, and the movable part is in sliding connection with the fixed part so as to slide in the extending direction of the fixed part; and a driving mechanism which is used for driving the movable part, so that the bearing can slide relative to the base along with the movable part to adjust the height position. The transfer device is simple in structure, stable and reliable in movement mode and convenient to debug and maintain.

Description

technical field [0001] The invention relates to the field of fans, in particular to a transfer device and a screen printing machine with the same. Background technique [0002] In the production process of solar cell components, the production of cells is the core part of the entire solar cell component production process. The main production processes of cells are: texturing, diffusion, wet etching, thin film deposition, electrode printing and sintering. In the process of printing electrodes, the method of screen printing is generally used. Generally, the screen printing machine is equipped with printing components composed of scrapers, ink return knives and screen plates, so as to be carried on the transfer mechanism such as a turntable. Electrodes are printed on the incoming silicon wafer. [0003] In order to enable the printing components to be located in a suitable working position directly above the silicon wafer to be printed, the screen printing machine also inclu...

AI Technical Summary

Problems solved by technology

[0004] The existing transfer device includes multiple sets of screw lifting mechanisms driven by synchronous belts. During the assembly and debugging process, multiple sets of lifting mechanisms need to be adjusted repeatedly to keep the screen printing platform level. After the failure, the disassembly, maintenance and reassembly process of the transplanting mechanism is relatively cumbersome and takes a lot of time, and the production line has a long downtime, which affects the production capacity of the production line

[0005] In addition, in the existing transfer device, the bottoms of the screw rods of multiple sets of screw lifting mechanisms are connected with synchronous wheels, and each synchronous wheel is driven by the same synchronous belt. Once the synchronous belt breaks or any screw is broken, each synchronous wheel will lose its Relatively fixed holding force, so that the transplanting mechanism loses its support for the screen printing platform, and the screen printing platform will hit the machine under the action of gravity, damage the printing machine, and even cause personal injury accidents
