Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic production equipment, and specifically relates to an automatic tape adsorption and shearing turntable. Background Art

[0002] During the production process of solar cell modules, the battery strings on the modules will be offset due to the inertia of the conveyor belt, so the battery strings need to be fixed in position. Currently, most of them are fixed by manual tape, that is, the operator sticks the tape horizontally along the gap between two battery strings, and the tape is pasted on the module in an offset manner. The manual trimming method is time-consuming, labor-intensive, and inefficient. The module body is prone to fragmentation and hidden cracks, and the product consistency is poor.

[0003] The existing automatic tape sticking machine for photovoltaic modules is equipped with a tape sticking mechanism at its execution end. The tape needs to be fed, cut, grabbed and stuck during the sticking process. The existing tape sticking mechanism, such as a new type of wheel-type tape sticking mechanism patented in China, has a notice number of CN215402198U. The automatic sticking of the tape is achieved by arranging a rotating shaft, a fixed ventilation block, a rotating ventilation block, a rotating spacer, an adsorption unit, a hose and other components in the rotating sticking mechanism. However, the end faces of the rotating ventilation block and the fixed ventilation block in the patent are tightly sealed. When this structure is actually used, as the relative rotation wear of the rotating ventilation block and the fixed ventilation block continues to increase, the gap between the rotating ventilation block and the fixed ventilation block will also increase, causing the tape sticking mechanism to leak, and finally weakening the adsorption force of the adsorption unit, thereby reducing the quality of tape sticking.
