Gripper device of automatic silicon wafer loading and unloading machine

Abstract

The invention relates to a gripper device of an automatic silicon wafer loading and unloading machine. The gripper device comprises an equipment support, a working table top mounted on the support, a guide rail mounted on the working table top, conveyer belts, a gripper mechanism, a driving device for controlling the movement of the gripper mechanism, and an operating panel for controlling the movement of the whole device, wherein the gripper mechanism is mounted in a track of the guide rail and comprises a first gripper used for absorbing silicon wafers; the conveyer belts used for conveying the silicon wafers are respectively arranged at the two ends of the guide rail; a material loading table used for providing the silicon wafers is arranged between the two conveyer belts; the gripper mechanism further comprises a second gripper parallel with the first gripper and mounted in one side direction of the first gripper; and the spacing between the first gripper and the second gripper is equal to the distance between each conveyer belt and the material loading table. The gripper device has the advantages that through adding one gripper, cell slices are absorbed by the second gripper when being loosened by the first gripper, and vice versa, thereby saving the operation time and improving the efficiency.

Description

technical field [0001] The invention relates to a device for producing solar cell sheets, in particular to a gripping device of an automatic loading and unloading machine for silicon wafers used in the production of solar cells. Background technique [0002] At present, the development of the domestic photovoltaic industry is in a stage of rapid growth, and solar cell manufacturers are developing rapidly. As a new energy high-tech industry, most domestic solar cell manufacturers have a low degree of automation and are still labor-intensive. The low degree of automation, on the one hand, limits the further expansion of the scale of the enterprise, and on the other hand, also has a negative impact on the stability of product quality. [0003] In the production of solar cells, the wafer cleaning process concentrates a large number of operations. The traditional cleaning process is to manually insert the stacked silicon wafers in the box into the carrying flower basket, and th...

AI Technical Summary

Problems solved by technology

The automatic equipment has a gripper with a suction cup. The stacked cells are placed in the middle of the equipment workbench. There is an air blowing device on the outside of the cells to blow off the stacked cells to prevent multiple cells from being adsorbed together. There is a conveyor belt on each side. When loading materials, the gripper with the suction cup absorbs the cells from the middle position and then moves left and right to place the cells on the conveyor belts on both sides respectively. At the end of the conveyor belt is placed a flower basket lying on its side, and there is a riser under the flower basket. The mechanism gradually rises with the insertion of the battery sheet, and the opposite is true when unloading, but in this patent, there is such a problem that when the gripper moves to one side, the other side is in an idle state, so it is a waste of time and the efficiency is not high enough
