Description

Technical Field

[0001] This utility model relates to the field of battery string production equipment technology, and more specifically, to a double-sided gluing device and production equipment for use in gridless battery strings. Background Art

[0002] There are two main types of existing battery cell stringing technologies: the first is to apply adhesive to the battery cells to bond the solder ribbons and the battery cells into a string, and the second is to form an alloy by heating the solder ribbons and the battery cells with infrared lamps to connect them into a string.

[0003] When grid-less solar cells are strung together, the first method involves applying adhesive between the solar cell and the solder ribbon. This can easily lead to loose contact between the grid lines and the solder ribbon, resulting in high resistance and consequently, low photovoltaic cell conversion efficiency and a high defect rate. The second method results in lower alloy bonding strength between the solder ribbon and the solar cell, making it prone to desoldering and poor soldering, which reduces the cell's power output. Therefore, a double-sided adhesive application device and production equipment for grid-less solar cell strings are provided to address the problem of low solder ribbon bonding strength after grid-less solar cell strings are strung together. Utility Model Content

The adhesive application mechanism applies adhesive to the solder strips on the front or back of the gridless battery string based on the positioning information from the photographing mechanism. The UV curing mechanism cures the adhesive on the front or back of the gridless battery string after adhesive application.

[0017] Compared with the prior art, the beneficial effects of this utility model on the double-sided coating device and production equipment applied to gridless battery strings are as follows:

[0018] This invention relates to a double-sided adhesive application device and production equipment for grid-less battery strings. After the solder strips and grid-less battery cells are strung together, an adhesive application operation is performed above the solder strips on both the front and back sides of the grid-less battery string. First, the front side of the strung battery cells is photographed and positioned. Then, the front UVW alignment platform assembly and adhesive application steel mesh assembly work together to real-time compensate for alignment and apply adhesive, which is then cured by a front UV lamp. Next, the grid-less battery cells are flipped so that the back side faces upwards using a flipping and transfer assembly. The back side of the strung battery cells is then photographed and positioned. Then, the reverse UVW alignment platform assembly and adhesive application steel mesh assembly work together to real-time compensate for alignment and apply adhesive, which is then cured by a back UV lamp. This allows the solder strips on both sides to adhere to the battery cells using UV adhesive, achieving a certain adhesion strength. This effectively solves the problem of low solder strip connection strength after the grid-less battery strings are strung together. Attached Figure Description

The gridless battery string below 37 is coated with adhesive on the solder strips on the front side, and then UV cured by the first UV curing mechanism 14. After the front UV curing, the gridless battery string is transferred to the docking conveyor belt 112. Then, the flipping component 20 flips the gridless battery string on the docking conveyor belt 112 180 degrees. The transfer component 30 transfers the gridless battery string flipped over from the flipping component 20 to the second adhesive coating transfer component 40, and applies adhesive to the solder strips on the back side of the gridless battery string for curing, thereby completing the adhesive coating and curing operation of the solder strips on both sides of the gridless battery string.
