Background
Photovoltaic is a novel power generation system for directly converting solar radiation energy into electric energy by utilizing the photovoltaic effect of a solar cell semiconductor material, and has two modes of independent operation and grid-connected operation. The photovoltaic panel assembly is a power generation device capable of generating direct current when being exposed to sunlight, and comprises a thin solid photovoltaic cell almost entirely made of semiconductor materials (such as silicon), and particularly comprises a glass plate, an EVA adhesive layer, a cell piece, a back plate, a junction box, a frame and the like, wherein the materials above nine can be recycled, and the photovoltaic panel assembly has considerable recycling value and higher economic benefit, so that the photovoltaic assembly after reaching the service life needs to be recycled, the problem of shortage of raw materials of the photovoltaic device is relieved to a certain extent, and the pollution to the environment is avoided.

In short, the stripping roller and the driving roller utilize the rotating speed difference between the stripping roller and the driving roller to form larger stripping force between the backboard of the photovoltaic module and the cullet, so that the stripping efficiency can be remarkably improved, and meanwhile, unlike the existing extrusion mode, the stripping roller can scrape off the cullet by combining with the zigzag structure when rapidly rotating, so that the stripping effect is improved.
However, in the above peeling process, the following drawbacks are evident:
1) As the stripping is performed in the opposite movement, the stripped battery sheet may undergo relative movement with the stripping roller having a high speed (particularly, a change in the stripping position is very remarkable) and may change the stripping angle change (for example: upwarp), thus the depth contacted by stripping cannot be controlled uniformly, so that the stripping force is uneven, the stripping quality is poor, and the glass residue rate is higher;
2) The peeled chips and the battery pieces cannot be effectively separated, so that the probability of re-adhering the peeled chips to the battery pieces is high;
3) Breaking of the glass is required before peeling is performed, and only the broken glass can enter between the peeling roller and the driving roller, so that a process and peeling cost are increased in terms of peeling means.
