[0027] The utility model capacitor film surface detection device, including detection stage 1 and setting detection subassembly 11 of detection stage 1 one side, detection subassembly 11 includes frame 111 and the detection head 112 of rotation connection in frame 111 and located detection stage 1 directly above, and the both ends of detection stage 1 are provided with the winding roller 13 for winding capacitor film and the unwinding roller 14 for releasing the capacitor film of detection, and the motor 15 for driving winding roller 13 is provided at winding roller 13, and the adjusting part 2 is provided at unwinding roller 14, and the adjusting part 2 includes mounting bracket 21 and the follow-up plate 23 of sliding connection on mounting bracket 21, and the follow-up plate 23 is elastically arranged on mounting bracket 21 through the first spring 22, and the height of follow-up plate 23 changes with the thickness of the capacitor film to be detected wound on unwinding roller 14, and the elastic telescopic link 26 is jointly rotatably connected between follow-up plate 23 and detection head 112, and the adjusting part 2 is used for adjusting the horizontal angle of detection head 112 to make the surface where detection head 112 is located parallel to the film surface to be detected, and the parallelism between detection head 112 and the film surface can be maintained through the setting of adjusting part 2, and the detection accuracy is improved.

[0028] Specifically, the both ends of follow-up plate 23 are fixedly connected with the first sliding block 25 arranged in T-shaped section, and the first sliding groove 24 with the size matched with the first sliding block 25 is formed in mounting bracket 21, so that accurate guiding and stable sliding are provided, the movement of follow-up plate 23 is stable, and the stability of the rotation of detection head 112 is ensured.

[0029] Among them, the elastic telescopic link 26 includes the main rod 261, the auxiliary rod 262 and the second spring 266 for connecting the main rod 261 and the auxiliary rod 262, the main rod 261 is rotatably connected with the detection head 112, the auxiliary rod 262 is rotatably connected with the follow-up plate 23, and the setting of the elastic telescopic link 26 ensures that the follow-up plate 23 can drive the detection head 112 to rotate in the process of moving up and down.

[0030] Further, the movable slot 263 for the movement of the auxiliary rod 262 is formed in the main rod 261, one end of the auxiliary rod 262 is fixedly connected with the second sliding block 265 arranged in T-shaped section, and the two second sliding grooves 264 are correspondingly formed in the movable slot 263, the second sliding grooves 264 do not penetrate the movable slot 263, and the setting of the second sliding grooves 264 can limit the auxiliary rod 262 while avoiding the auxiliary rod 262 from sliding out of the movable slot 263.
