Description

Technical Field

[0001] This application belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a tooling and film conveying device. Background Technology

[0002] To improve the photoelectric conversion efficiency of photovoltaic cells, the industry has proposed a new type of gridless (OBB) solar cell. OBB cells only have sub-busbar lines printed on their front and back sides. Since there are no main busbars, electrical connections between the solder ribbon and each sub-busbar line are required to collect current from all sub-busbars. Traditional stringing methods, which involve soldering the ribbon to the OBB cell, often fail to create a strong bond between the ribbon and the sub-busbar lines, resulting in poor adhesion. Therefore, a coating is now needed on the surface of the cell string to secure the solder ribbon to the OBB cell surface.

[0003] To improve production efficiency, currently, tooling and membranes are transported separately to the loading station using a tooling and membrane conveying device. At the loading station, the tooling is positioned above the membranes. A single transport mechanism then simultaneously moves the vertically arranged tooling and membranes onto the battery strings. Because the tooling at the loading station is above the membranes, the inspection mechanism cannot inspect the membrane's position from above, making it impossible to determine the membrane's accuracy at the loading station. If the membrane is misaligned, it will protrude from the battery cells after being attached, affecting the quality of the battery strings. Utility Model Content

[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0053] In order to improve the photoelectric conversion efficiency of the photovoltaic cell, the industry proposes a new type of main grid-free (0BB) cell piece. The positive and negative surfaces of the main grid-free cell piece are only printed with auxiliary grid lines. Since there is no main grid on the cell piece, in order to realize the collection of current on all auxiliary grid lines on the cell piece, it is required that the solder strip is electrically connected with each auxiliary grid line. In the traditional string assembly mode of welding the solder strip to the main grid-free cell piece, the solder strip and the auxiliary grid line cannot form a firm connection, and the bonding force between the solder strip and the main grid-free cell piece is very poor. Therefore, it is now necessary to fix the solder strip on the surface of the main grid-free cell piece by coating a film on the surface of the cell string.

[0054] In order to improve production efficiency, the tooling and the film are currently transported to the feeding station by the tooling and the film transport device respectively, the tooling at the feeding station is located above the film, and then the same handling mechanism is used to synchronously handle the tooling and the film arranged in upper and lower positions to the battery string. Since the tooling at the feeding station is located above the film, the detection mechanism cannot detect the position of the film from above the tooling, and thus cannot determine whether the position of the film at the feeding station is accurate. If the position of the film is skewed, it will cause the film to protrude from the battery sheet after the film is subsequently attached to the battery sheet, affecting the quality of the battery string.
