Embodiment Construction

[0021] Such as Figure 1-Figure 3 As shown, the calibration method implemented in the present invention can simply and accurately calibrate the photovoltaic solar tube type PECVD graphite boat, solve problems such as chip loss, scratches and fragment alarms caused by the graphite boat, improve the qualification rate of the battery sheet, and increase the workshop output.

[0022] When the present invention is implemented, a graphite boat calibration platform is required, and the graphite boat calibration platform includes a base whose upper surface is horizontal, fixed blocks fixed on the left and right ends of the base, positioning blocks respectively fixed on the left and right ends of the base and outside the fixed block, A plurality of blocks at equal intervals between two fixed blocks, a stand on the front side of the base, the two fixed blocks are the same, the two positioning blocks are the same and the height of the positioning block is higher than the fixed block, and...

Abstract

The invention relates to the field of solar cell production. The invention relates to a method for calibrating a tubular PECVD graphite boat, and the method comprises the following steps of firstly, manually detecting whether a graphite boat connecting block and a boat sheet to be calibrated are broken, deformed or damaged, if so, replacing in time, manually detecting whether foreign matters existin the graphite boat to be calibrated or a sticking point, and if so, cleaning or washing in time; and then placing the graphite boat to be calibrated on a calibration table for detection. The calibration method of the embodiment of the invention can simply and accurately calibrate the photovoltaic solar tubular PECVD graphite boat, solves the problems of chip falling, scratching, chip breaking alarm and the like caused by the graphite boat, improves the percent of pass of battery pieces, and increases the yield of a workshop.

Description

technical field [0001] The invention relates to the field of solar cell production. Background technique [0002] Photovoltaic solar tube PECVD (Plasma Enhanced Chemical Vapor Deposition) uses a graphite boat as a carrier to realize the coating process. After the graphite boat has been used for a period of time, due to the excessive coating on the graphite boat, the electrical conductivity is not good, which affects the quality of the battery coating. Therefore, it needs to be cleaned by dismantling the graphite boat. After cleaning, the disassembled boat pieces are assembled into graphite boats again. After the assembly is completed, the graphite boat needs to be calibrated. If there is no calibration, the positions of the graphite boats are not parallel and misaligned, and problems such as chip dropping, scratching, and broken chip alarms will occur during the production process. In this way, not only the qualification rate of the battery sheet is reduced, but also the...
