1, working principle As the name implies, a laminator is a mechanical device that presses together multiple layers of material. A vacuum laminator is a mechanical device that presses multiple layers of material under vacuum conditions. Vacuum laminators are used in solar cell assembly production lines. We call it a solar cell module laminator. No matter what kind of job the laminator is applied to, the working principle is the same. That is, exerting a certain amount of pressure on the surface of the multilayered substance, these substances are tightly pressed together. The different things vary according to the purpose of lamination, and the conditions for lamination vary. 2, the role of laminators in the production of solar cells The process flow of the solar panel assembly line is as follows: Front-end stacking, laminating, curing, frame assembly, test The purpose of the process is: raw materials, battery panels, and finishing The solar cell module laminator is a key device for realizing the transition from raw materials to solar panels. Before laminating, we can see the material composition of the solar panel from the laying of this process (in the case of ordinary components): 1, glass 2, EVA 3, connected cell 4, EVA 5, backplane The role of the laminator is to press these materials together and require them to be pressed together to achieve the following objectives: 1, No bubbles after pressing (<2 pcs/inch) 2, to melt into one 3, there must be a certain degree of bond strength between materials that cannot be fused. In order to achieve these three goals, the following conditions must be met: a, pressure b temperature, c, vacuum degree d, time The four conditional laminating machines are necessary for the production of solar cells. Definition: The solar cell module laminator meets all the above four conditions of laminating equipment. Laminator structure 1 Composition: Structure + Temperature Control + Power System + Vacuum System + Control Section A total of 5 parts. Here only the structure part is introduced: The structure of solar cell laminator is divided into upper chamber vacuum, lower chamber vacuum, upper cover, lower case and frame body.

U Nails
U nails refer to a kind of fasteners with two-pronged shanks. These U nails are usually used for attaching the mesh fences to wooden posts and frame, hence the name fencing staples. These practical nails can fix the wire, rope even Barbed Wire to the ground, wooden post or stakes. Therefore, people like to use them in agriculture & gardening, viticulture & other fruit growing, animal coops & plant trellises construction.
