Problems solved by technology

[0007] The existing method of manual picking of bent cells is highly uncontrollable. If it is not found in time, the bent cells will be transported with the conveyor belt, and debris will also be generated.
Moreover, in order to complete the picking work, each production line needs to increase the corresponding staff, th

Abstract

The invention provides a bending piece detection device for a battery piece testing procedure. By the device, a fragmentation ratio of the testing procedure can be obviously reduced, and automatic degree of detecting the bending piece can be improved. The bending piece detection device comprises a photoelectric sensor and an indicator, wherein the photoelectric sensor is arranged at the side of a transmission belt and is used for detecting bending pieces existing on the transmission belt; and the indicator is in signal connection with the photoelectric sensor and can send an indication signal indicating that the bending pieces exist on the transmission belt to an operator. The photoelectric sensor detects whether the bending pieces exist on the transmission belt through a photoelectric path; and if the bending pieces are detected, a detection signal is transmitted to the indicator, and the indicator sends the indication signal indicating that the bending pieces exist on the transmission belt so as to alarm the operator to take out the bending pieces, so that the bending pieces are automatically detected. The operator only needs to take out the bending pieces; the fussy processes of manually picking up the bending pieces in the prior art are avoided; the detection precision is improved; and the labor cost is saved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a bending piece detection device used in the battery sheet testing process. Background technique [0002] The processing steps of battery sheets will vary according to different manufacturers, but almost all battery sheets must go through three processes: printing electrodes, sintering, and testing and packaging. [0003] The so-called sintering is to sinter the battery sheet after printing the electrodes at a high temperature in an appropriate atmosphere to volatilize the printed paste solvent, so that the paste and the silicon wafer can basically form a good contact, and then form the two poles of the battery . One of the sintering methods is called back firing, which is a sintering method in which the back of the cell goes through the sintering device. [0004] After the cells are sintered, in order to facilitate the grouping or packaging of the cells, the cells need to ...
