The invention provides a high-efficiency solar cell double-glass component tape-positioning automatic edge-sealing device and its edge-sealing process with simple structure, high degree of automation, simple process and labor-saving. The adhesive tape first positioning type automatic edge banding device for solar cell double-glass modules of the present invention includes an edge banding head, which is characterized in that: the edge banding head includes a bracket, and a tape material roll and a guide belt corresponding to the tape material roll are arranged on the bracket The wheel set, corresponding to the guide pulley at the end, is provided with an upper compacting roller assembly, a folding roller assembly, a shaping roller assembly, an edge wrapping roller assembly and a lower compacting roller assembly in sequence; The rotating shafts of the upper compacting rollers of the upper compacting roller assembly are parallel to each other.

Description

technical field [0001] The invention belongs to the technical field of automatic production equipment of solar cell modules, and in particular relates to a solar cell double-glass module adhesive tape first positioning type automatic edge sealing device and its edge sealing process. Background technique [0002] In the automatic packaging process of conventional double-glass solar cell modules, the requirements for both the quality of the edge banding and the reliability of the edge banding device are getting higher and higher. Because the module can be manufactured with a glass thickness ranging from 2mm to 4mm, and an EVA thickness ranging from 0.5mm to 1mm. The thickness of the material selected by different manufacturers is different, so the width of the adhesive tape on the glass surface is also different. The current common edge banding device is difficult to meet the requirements of the edge banding process, which is mainly manifested in two aspects: on the one hand,...

Problems solved by technology

The current common edge banding device is difficult to meet the requirements of the edge banding process, which is mainly manifested in two aspects: on the one hand, the edge banding effect of the tape is unqualified in many ways, 1. The tape is not pasted in place, and the end is detached from the component; 2. The adhesive tape is biased, and the vent hole on the tape is dislocated up and down, resulting in the vent hole being blocked, which will directly lead to the scrapping of the component (ensuring the position of the tape vent hole is of great significance to the thermal packaging of the component); 3. The tape is in the component The flatness and consistency of the upper and lower glass surfaces also directly affect the overflow effect of EVA hot melting

The width of the upper and lower glass tapes is not equal, the tape is separated from the glass, and the tape is wrinkled, etc., all of which affect the packaging quality of the dual-wave module

On the other hand, in the edge banding process, every process link that the tape passes through cannot be controlled, resulting in greatly reduced reliability of the edge banding, and there are obvious differences in the shape of the paste, resulting in quality problems such as folds, slack, and irregular shapes of the edge banding. occur

[0003] In addition, due to the limitation of the structure of the existing edge banding device, the edge banding process is cumbersome, the production cycle is slow, and the efficiency is low

It can be seen that the structure of the edge banding device of the dual-wave module is complicated, and the edge banding process is cumbersome, time-consuming and laborious, which are the main disadvantages that lead to prolonged production cycle time and low production efficiency
