Problems solved by technology

However, in the process of scribing the surface of the workpiece with the existing 100-grid knife, the size of the scribing force is completely determined by the worker's feeling, which leads to uneven force during the scribing process, which in turn leads to uneven scribing depth. Large differences in depth, which in turn can affect the results of the adhesion test
In addition, the existing cross-cutting knives cannot ensure that the directions of the two cross-cuts are perpendicular to each other when cross-cutting in two directions

Abstract

The invention discloses a device for testing the adhesive force of a raw material of a photovoltaic module. The device comprises a seat body, a cutter, a display device and at least one pressure sensor. The upper end part of the cutter is connected in the seat body in a sliding manner, and the lower end part of the cutter is provided with at least one cutter tooth suitable for scribing on a workpiece; the pressure sensor is arranged between the upper end part of the cutter and the seat body and is suitable for collecting the acting force of the cutter teeth on the workpiece; and the display device is connected with the output end of the pressure sensor and is suitable for receiving a pressure signal generated by the pressure sensor and correspondingly displaying the pressure signal. According to the device, the uniformity of the scribing depth on the surface of the workpiece can be improved, and the large difference of the scribing depth is avoided.

Description

technical field [0001] The invention relates to a device for testing the adhesion of photovoltaic module raw materials. Background technique [0002] At present, when testing the adhesion of the adhesion layer on the surface of the workpiece, it is necessary to use a cross-cutting knife to cross the two directions perpendicular to each other on the surface of the workpiece, and then stick an adhesive tape on the grid and let it stand for a period of time Finally, tear off the tape and observe the detachment of the adhesion layer. However, in the process of scribing the surface of the workpiece with the existing 100-grid knife, the size of the scribing force is completely determined by the worker's feeling, which leads to uneven force during the scribing process, which in turn leads to uneven scribing depth. The difference in depth is large, which in turn can affect the results of the adhesion test. In addition, the existing cross-cutting knives cannot ensure that the direc...
