The embodiment of the application provides a solar cell high-speed splitting mechanism and a splitting device, which solve the technical problem that in the prior art, the cell 100 is subjected to hidden splitting in the splitting process; the technical effect of reducing the occurrence of hidden cracks of the battery piece 100 in the splitting process is achieved.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In the photovoltaic field, solar cell strings are receiving wide attention in the industry, the solar cell strings mainly use a laser cutting technology to scribe and cut the whole cell sheet 100 to a certain depth according to a preset pattern, then conductive adhesive is smeared on printing points of the cell sheet 100, each cell strip 102 after the whole cell sheet 100 is split is overlapped and arranged, and then the cell strings are obtained after curing.
The dicing is to dice and cut the whole battery 100 to a certain depth according to a predetermined pattern by using a laser cutting technology, and the depth is 60% -70% of the thickness of the battery 100, that is, a plurality of cutting lines 101 are cut on the battery 100; the battery plate 100 is split along the cutting line by a splitting technology, so as to obtain a plurality of battery strips 102 with the same size. Specifically, the cutting lines are generally distributed on the battery plate 100 at equal intervals and in parallel, and the battery plate 100 can be split into the battery strips 102 along the cutting lines by the action of external force. That is, a plurality of cutting lines are formed on a piece of the battery piece 100, and once the battery strip 102 is obtained by breaking along one cutting line, the whole battery piece 100 needs to be subjected to multiple breaking processes, and the battery piece 100 is sequentially broken along the cutting lines to obtain a plurality of battery strips 102; specifically, the cutting lines 101 are generally distributed on the battery plate 100 at equal intervals and in parallel, and the battery plate 100 can be split into the battery strips 102 along the cutting lines 101 by the action of external force.
There is also a problem with transporting the battery strip 102 during the breaking process. After the battery piece 100 is split to obtain the battery strips 102, the battery strips 102 are relatively close to the original battery piece 100, and the battery strips 102 obtained in the next split are easy to interfere with the previous battery strip 102, that is, the possibility of collision exists between two adjacent battery strips 102, so that after the split operation is completed, the battery strips 102 need to be transported in time, and collision between the battery strips 102 is prevented. Because a plurality of battery strips 102 are obtained after a piece of battery piece 100 passes through the splitting, and the time interval between two splitting actions of the battery piece 100 is short, that is, the battery strips 102 need to be transported quickly after one splitting, the precision and the frequency of transporting the battery strips 102 after each splitting by using a mechanical arm and other equipment are high, and the transporting equipment such as the mechanical arm is not practical in the narrow space of the splitting mechanism, so that the transporting or guiding of the previous battery strip 102 needs to be carried out while the next splitting action.
The application provides a solar cell high-speed splitting mechanism which acts on a cell 100 subjected to scribing treatment, and is stressed on the cell 100, so that the cell 100 is split along a line, and a cell strip 102 is obtained. As shown in fig. 2, a solar cell high-speed breaking mechanism comprises a base 200 and a breaking assembly 300, wherein the base 200 is used as a mounting base of the mechanism for connecting and mounting the breaking assembly 300, and the breaking assembly 300 acts on a cell 100 and completes breaking of the cell 100.
