Description

Technical Field

[0001] The utility model relates to the technical field of blanking of a velvet making machine, in particular to an automatic blanking device of a TOPCon battery velvet making machine. Background Art

[0002] In recent years, photovoltaic manufacturing companies have sprung up everywhere, new processes and new equipment have been frequently iterated, the production capacity of the TOPCon cell process route has been released in large quantities, and the production capacity of texturing machines and supporting automation efficiency have also gradually increased.

[0003] At present, the automatic unloading of each TOPCon production velvet machine is completed in four steps: horizontally moving out the whole flower basket - vertically transferring the rotating mechanism to the slide - camera line scanning - conveying unloading. At present, the rotating mechanism rotates the horizontal flower basket to the vertical slide to transfer it, the sensor on the vertical conveyor belt line of the slide detects whether there is a flower basket, and then it is transferred from the vertical slide to the camera line scanning. After the camera line scanning is completed, the vertical slide conveyor belt transfers the flower basket to each horizontal unloading location; the traditional method of automatic unloading, such as the increase of the process time of the velvet machine and the faster unloading speed, leads to the horizontal rotating mechanism of the flower basket unloading to complete the rotation of the flower basket and the vertical conveyor slide waiting for the vertical conveyor slide. The vertical slide conveyor line scanning and line scanning complete the unloading speed is too slow and it takes 5s. If the speed is too fast, there is no positioning and fixing device above the flower basket, which will cause the flower basket to fall down and cause the increase of various adverse conditions caused by the battery cell, thereby affecting the production line yield. At the same time, due to other uncontrollable factors, the operator's manual unloading is not timely, which will affect the unloading capacity of the velvet machine. In general, the traditional wool-making machine transfers the material vertically to the camera line scan point without positioning above. Since there is no positioning device above, the speed of the flower basket is slow. If the speed increases, there is a risk of the whole flower basket of battery cells falling down and breaking into pieces, affecting the yield and production capacity.

[0004] Therefore, the utility model designs a new type of high-efficiency battery structure, adds a vertical movable slide basket positioning function, improves material discharge efficiency, and reduces the occurrence rate of fragments, which obviously has practical significance.
