The utility model relates to a film peeling fixture, which comprises a front plate, a rear plate located behind the front plate, and a base fixed with the rear plate. A downward rectangular opening is arranged in the middle of the lower part of the front plate, a screw hole is arranged in the four corners of the front plate, and a screw hole is arranged in the four corners of the corresponding rear plate. The test sample is clamped between the front plate and the rear plate through four screws. One end of the 3M tape is attached to the test surface of the test sample, and the other end is fixed to the tensiometer. The back surface of the front plate is 5 cm along the three sides of the rectangular opening, and the surrounding area is roughly treated. In the middle of the front and lower parts of the rear panel, there is a perimeter corresponding to the front panel, which is roughly treated. The scheme has good practicability, reasonable structure design, no damage to the surface of the test sample, good stability and accurate test results.

一种薄膜剥离夹具
本技术涉及电池制造领域,尤其涉及一种薄膜剥离夹具。
技术介绍
随着薄膜技术的发展,越来越多的薄膜应用到实际生活中,其中将薄膜镀在基材上,可实现额外的功能或保护作用,例如在PET薄膜表面上镀上微米级厚度的ITO(掺锡氧化铟(IndiumTinOxide),一般简称为ITO),原本不导电的PET薄膜表面可实现导电。高质量的薄膜首先应与基材有良好的结合。目前市场上对薄膜附着力的测试方法主要是纸带摩擦法、酒精耐磨法以及3M胶带法等,其中3M胶带法因操作简单,被广泛应用。在电池制造厂,需要对各种薄膜的附着力进行180°的剥离力测试。如何对镀有薄膜的测试样品进行固定是测试中的关键一步。现有薄膜测试样品固定方式主要有两种:(1)用简单夹具将测试样品端固定,再用3M胶带粘在测试面上进行测试,3M胶带另一端使用拉力计以一定角度(180°)将3M胶带从样品测试面剥离进行测试,存在容易损坏样品表面,导致废率品上升的缺陷;(2)用双面胶将测试样品贴在平板上(例如钢板),再用3M胶带粘在测试面上进行测试,3M胶带另一端使用拉力计以一定角度(180°)将3M胶带从样品测试面 ...
