Abstract

The invention discloses a PERC battery back passivation gas spraying device in the technical field of PERC batteries. The PERC battery back passivation gas spraying device comprises a fixing support,a limiting clamping ring is arranged on the front end surface of the fixing support, a clamping sealing device is movably arranged on the inner wall of the limiting clamping ring, and telescopic sleeve rods are arranged on the left side and the right side of the bottom of the fixing support. The bottom of the telescopic sleeve rod is connected with a supporting plate block, the top of the supporting plate block is connected with a spraying device, the bottom of the spraying device is connected with a telescopic rod, fixing rods are arranged on the left side and the right side of the bottom ofthe supporting plate block, and fastening devices are movably arranged on the left side and the right side of the top of the conveying plate block. The height of the spraying device is adjusted to adjust the air spraying amount, air is sprayed according to the size of the battery, and the sprayed air is comprehensively and evenly sprayed to the back face of the battery, so that the waste phenomenon is avoided; and position adjustment is conducted according to the size of the battery, so that it is guaranteed that the battery can be more stable and cannot deviate during passivation, and the quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of PERC batteries, in particular to a passivation gas spraying device on the back of PERC batteries. Background technique [0002] When performing gas passivation on the back of the battery, the amount of gas sprayed by the existing gas spray device is fixed, and the support platform used to prevent the battery on the spray device cannot be adjusted and fixed according to the belt of the battery , so that the gas in the spraying device will cause waste, the battery is not fixed well, and the phenomenon of offset during the passivation process is prone to occur, which affects the efficiency of the passivation of the battery. To this end, we propose a passivation gas spray device on the back of PERC cells. Contents of the invention [0003] The object of the present invention is to provide a passivation gas spraying device on the back of a PERC battery to solve the problems raised in the above-mentioned bac...
