Embodiment
[0036] as Figure 1-4 As shown in the figure, a new multi main grid solar cell module repair tool includes a holding and positioning body 2. The holding and positioning body 2 is composed of a plurality of left and right symmetrical heat conduction branches 3. The holding and positioning body 2 is symmetrically connected with the semicircular pinch handle 1 from top to bottom. The side wall of the heat conduction branch 3 is provided with semicircular welding holes, which correspond to the welding connection parts between the front and rear battery chips and the repaired and replaced battery chips, The heat conduction branch 3 is fixedly embedded with an electric heating rod 6. The electric heating rod 6 is connected with the single chip microcomputer 7 through a high temperature resistant signal cable. The single chip microcomputer 7 carries out real-time feedback control and adjustment of the temperature of the electric heating rod 6 through the inherent temperature control progr...

Abstract
The invention belongs to the technical field of solar cell assembly production, and in particular relates to a novel multi-busbar solar cell assembly repair tool and its repair method. Composition, the pressing and positioning main body is symmetrically connected to the semicircular pinch handle up and down, and the side wall of the heat conduction branch is provided with semicircular welding holes, and the welding holes correspond to the welding connection parts of the front and rear battery slices and the reworked replacement battery slices An electric heating rod is fixedly embedded in the heat conduction branch, and the electric heating rod is connected to a single-chip microcomputer through a high-temperature-resistant signal cable, and the single-chip microcomputer performs real-time feedback control and adjustment of the temperature of the electric heating rod through an inherent temperature control program. The invention can reduce the power loss attenuation of multi-busbar batteries caused by cracks and fragments of the battery, can continue to maintain good power generation performance, can make the battery evenly heated and the temperature can be adjusted and controlled, and has high reliability and high efficiency. , can achieve mass production repair.
Description
technical field [0001] The invention belongs to the technical field of solar cell module production, in particular to a novel multi main grid solar cell module repair tool and its repair method. Background technology [0002] In the multi main grid battery repair industry, the conventional flat welding strip battery repair process is generally adopted. The flat welding strip on the repaired battery is heated and separated by using a flat iron, and then the battery of the same specification with good appearance, performance quality and consistent electrical performance is selected to lay and replace the battery at the position to be repaired. The flat iron is used to weld the battery at a certain temperature and pressure, A good alloying connection is realized between the battery electrode and the tin coated solder strip. [0003] The existing multi main grid battery repair methods have the following shortcomings: 1. The whole process of removing NOK battery is easy to damage the ...
