[0003] However, in order to make it easier for the leads to extend to the side of the high-temperature cloth spacer away from the photovoltaic backplane through the through holes provided on the high-temperature cloth spacer, the through-holes and the leads are clearance fits, so that when the photovoltaic backplane, battery sheet And in the process of glue between the photovoltaic backplane and the battery sheet, part of the glue that passes through the photovoltaic backplane will pass through the high-temperature cloth pad through the gap between the hole wall and the lead, and extend to the high-temperature cloth pad Lead bonding on the side of the block away from the photovoltaic backplane, which in turn leads to poor soldering of the leads extending to the high temperature cloth spacer on the side away from the photovoltaic backplane

Embodiment Construction
[0025] Embodiment 1 of the present application provides a high-temperature cloth cushion block. The cloth cushion body has opposite front and back sides. The first slit runs through the cloth cushion body from the front along the thickness direction of the cloth cushion body. The first slit includes the connected second The slit section and the second slit section allow the lead wires connected to the cells to extend through the first slit on the cloth pad body to a side of the cloth pad body away from the photovoltaic backboard after passing through the photovoltaic backboard. side, and after the lead wires pass through the first cut, the warped part of the cloth pad body can be pressed together, so that in the process of pressing the photovoltaic backplane, the battery sheet and the glue between the photovoltaic backplane and the battery sheet In the process, the glue passing through the photovoltaic backplane is blocked between the photovoltaic backplane and the high-tempera...

Abstract
The embodiment of the invention relates to the technical field of photovoltaic module manufacturing, in particular to a high-temperature cloth cushion block which is used for being laid on the side, away from a battery piece, of a photovoltaic back plate. The cloth cushion block comprises a cloth cushion body and a first notch, and the cloth cushion body is provided with a front face and a back face which are oppositely arranged; the first notch penetrates through the cloth cushion body from the front face in the thickness direction of the cloth cushion body, and the first notch comprises a first notch section and a second notch section which are connected. In addition, the embodiment of the invention also provides a manufacturing method of a photovoltaic module. According to the high-temperature cloth cushion block provided by the embodiment of the invention, in the process of laminating the photovoltaic back plate, the battery piece and glue located between the photovoltaic back plate and the battery piece, poor welding of a lead extending to one side, far away from the photovoltaic back plate, of the high-temperature cloth cushion block can be avoided.
Description
technical field [0001] The embodiments of the present application relate to the technical field of photovoltaic module manufacturing, and in particular to a high-temperature cloth pad and a method for manufacturing photovoltaic modules. Background technique [0002] At present, in the manufacturing process of photovoltaic modules, through holes are often opened on the high-temperature cloth pads first, and then the high-temperature cloth pads are laid on the side of the photovoltaic backplane away from the cells, so that the leads connected to the cells can pass through After passing through the photovoltaic backplane, it can extend to the side of the high-temperature cloth spacer away from the photovoltaic backplane through the through hole opened on the high-temperature cloth pad, so that the photovoltaic backplane, the battery sheet, and the photovoltaic backplane and the battery sheet are pressed together. In the process of the glue between the photovoltaic backplane, th...
