Embodiment Construction

[0041]The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention discloses a solar battery segment grid repair method, such as figure 1 As shown, the specific steps are as follows:

[0043] Step 1: Fix the solar cells on the fixing device 2, the controller 1 controls the driving mechanism to drive the fixing device 2 carrying the solar cells to move directly under the optical scanning device 4, and the optical scanning device 4 controls the solar energy on the fixing device 2 Battery slices to scan;

[0044] Step 2: The optical scanning device 4 transmits the scanning information to the controller 1. The scanning information includes the number of broken grids and the data information of the XY axis where each broken grid is located. T...

Abstract

A method and a device for repairing a broken gate line in a solar cell. Firstly, a solar cell is secured by a securing device (2), a controller (1) controls a driving mechanism to drive the securing device (2) carrying the solar cell to move to a position just below an optical scanning device (4), the optical scanning device (4) scans the solar cell on the securing device (2); then, the optical scanning device (4) transmits the scan information to the controller (1), the controller (1) determines whether the solar cell needs to be repaired according to the scan information, and classifies and repairs the solar cell needing to be repaired; the repaired solar cell is caused to flow into a sintering furnace (7), and the repair position of a broken gate line is sintered at high temperature; the solar cell sintered at high temperature is put into a receiving box (8). A repair device is provided according to the method for repairing a broken gate line in a solar cell, and the solar cell having a defect of the broken gate line can be screened and repaired, greatly reducing the proportion of defective products, and the manufacturing cost of the solar cell can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of producing solar cells, in particular to a method and device for repairing a grid of solar cells. Background technique [0002] Under the current situation of the photovoltaic industry, only by obtaining higher photoelectric conversion efficiency, higher quality rate and lower cost can the company survive and grow in the decisive competition. The company must do a good job in cost control and quality control. The finer it is, the lower the cost, and the problem of broken grid will follow. The current reduction of the battery with serious broken grid will affect the electrical performance of the whole module, and the power will be reduced. Chips are disposed of at a low price, resulting in a great waste of resources, so the research and development of solar cell broken grid repair technology has a great effect on cost savings. [0003] For example, the Chinese patent with the application number: 2201110169...
