[0034] The working principle of this utility model:

[0035] When the device is in use, the detection plate 218 with a polyimide film attached thereto is horizontally slid into the top of the mounting plate 206. While the detection plate 218 is inserted in place, the detection plate 218 pushes the ball 221 downward, and the ball 221 compresses the spring 223 by pushing the extrusion plate 222. When the detection plate 218 moves to the slot 220 and is aligned with the ball 221, the spring 223 releases elastic potential energy to push the extrusion plate 222 to reset, and the inclined surface of the top of the extrusion plate 222 pushes the ball 221 upward to snap into the slot 220. At this time, the detection plate 218 completes the limit.

[0036] Secondly, according to the detection requirements, the knob 203 is rotated, and the threaded sleeve 205 is pushed by the screw rod 204 to carry the mounting plate 206 to move relative to the clamping frame 104, so as to determine the angle at which the clamping frame 104 peels off the polyimide film. After the adjustment is completed, the polyimide film adhered to the top of the guide plate 219 is lifted up and placed inside the clamping frame 104, and the threaded member 107 is rotated to drive the clamping plate 105 to press against the other side of the polyimide film to complete the clamping and fixing. During the detection, the electric telescopic rod 102 is started to drive the tension sensor 103 and the lower clamping frame 104 to move upward, and the polyimide film is slowly peeled off on the surface of the detection plate 218 and the reading is obtained through the tension sensor 103;

[0037] In addition, when it is found before the test that the polyimide film fails to adhere evenly to the surface of the test board, the handle 213 is rotated toward the polyimide film, and the connecting block 215 drives the flattening roller 217 to contact the upper surface of the polyimide film. Then, the handle 213 is pushed until the limit shaft 212 can be pushed into the upper slide groove 208. At this time, the spring 1 216 contracts in the connecting frame 214 and pushes the connecting block 215, and then the flattening roller 217 is tightly pressed against the upper surface of the polyimide film. After that, the handle 213 is pushed back and forth, and the flattening roller 217 gradually flattens the polyimide film above the test board 218.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
