Automatically centering process piece box for solar cell piece

Abstract

The invention relates to an automatically centering process piece box for a solar cell piece. The automatically centering process piece box comprises a bottom plate, a fixing plate, four groups of side plate assemblies and a lifting plate. The four groups of the side plate assemblies form a square piece box on the bottom plate in an encircling mode. The four groups of the side plate assemblies are symmetrically and evenly arranged. Each group of the side plate assemblies is provided with two centering wheel assemblies which can automatically adjust a position of the solar cell piece and centralize the solar cell piece. Eight groups of the centering wheel assemblies are arranged. A centering wheel is arranged on each centering wheel assembly. Gaps between the centering wheels and the solar cell piece are automatically eliminated so that the position of the solar cell piece can be accurate to locate. The automatically centering process piece box enables the solar cell piece to be automatically centralized when the solar cell piece is grabbed by an equipment mechanical arm, automatically eliminates the gaps between the centering wheels and the solar cell piece, is used in cell piece laser ablation equipment and cell piece laser scribing equipment, can accelerate work speed, improves production efficiency, and effectively lowers piece-broken rate of the cell piece.

Description

technical field [0001] The invention relates to the technical field of production of crystalline silicon cells in solar energy manufacturing, and more specifically relates to a process box for automatically centering solar cells. Background technique [0002] Crystalline silicon solar cells are produced through the following processes: cleaning, diffusion, etching, PECVD, screen printing, sintering, etc., and the single cells are first neatly stacked in the solar cell box. The battery slices are picked up by the automatic manipulator of the equipment and transported to the next process. At present, in order to improve the power generation efficiency of solar cells, subsequent processes have been added, such as the laser ablation process in the back passivation process, and the laser scribing process in which the cells are divided into two, all of which require accurate positioning of the cells when they are grasped by the robot. centered. The accuracy of the position of th...

AI Technical Summary

Problems solved by technology

The position accuracy of the cell in the next process after capture can determine the length of the positioning time of the CCD image processing and affect the production cycle

The position of the cell in the cell is not accurate and centered, which also increases the rate of fragmentation when the manipulator grabs it

[0003] The cell box currently used in production has a large gap between the cell and the cell box. After the robot grabs it, the position deviation is relatively large, which brings a lot of calibration work to the laser ablation equipment and laser scribing equipment. The production rate is slow, and the probability of cell damage is also greatly increased.
