Mechanical arm for transferring solar cell piece basket and double-head transfer device for transferring solar cell piece basket

Abstract

The invention relates to a mechanical arm for transferring a solar cell piece basket and a double-head transfer device for transferring the solar cell piece basket. The double-head transfer device comprises mechanical arms, a portal frame, a vertical lifting mechanism fixedly arranged on the portal frame, and a lateral movement mechanism. Each mechanical arm comprises a vertically-arranged installing plate, a top plate fixedly arranged on the installing plate, an installing frame arranged on the top plate through a horizontal slide rail, a rotary table horizontally arranged on the bottom of the installing frame, a micromotion mechanism, a rotating mechanism arranged on the installing frame, and a vacuum system. A negative pressure sucker group adsorbs cell pieces by means of negative pressure provided by a vacuum generator. After the cells are adsorbed, the mechanical arms may start the rotating mechanism as required in a moved process in order to overturn a group of cell pieces by 180 degrees, thereby simplifying downstream work flows. Two baskets directly reach downstream equipment to be processed so that the downstream equipment configuration is simplified.

Description

technical field [0001] The invention relates to a manipulator used for a rotating basket of solar cells and a double-head transfer device using the manipulator for the rotating basket of solar cells. Background technique [0002] In the production process of solar cells, it is necessary to divide the original sheets into baskets, separate the pairs of multiple sets of cells that are bonded together, and then put them into the other two baskets to enter the next production link. Due to the rapid development of the photovoltaic industry , profit margins are reduced, labor costs are increasing, and job stability is declining. Attempts to replace labor with machinery have been going on. At present, the application of general-purpose six-axis robotic arms is basically realized to replace labor, but the price is high, and special fixtures need to be customized, and one of the two frames after the basket needs to be turned 180° to accommodate Downstream equipment, and the transshi...

AI Technical Summary

Problems solved by technology

In particular, there are 100 pairs (200 pieces) of batteries in the basket (quartz boat) after the heating furnace, and half of them need to be diverted after being divided into pieces. At present, due to the high cost and low efficiency of mechanization, many links still rely on manual work one by one. loading and unloading

Low efficiency, easy fragmentation, and damage to the cell will eventually affect the power generation efficiency of the cell and become a difficult technical problem to overcome
