[0051] Working principle:

[0052] In the first step, this application places the adhesive-backed product in a placement frame 2. When the positioning camera 304 detects that the placement frame 2 has moved below the laser array 303, the PLC controller 101 controls the laser array 303 to start emitting laser light towards the placement frame 2. The industrial camera 406 captures the laser light reflected by the adhesive-backed product. A local three-dimensional contour of the adhesive-backed product is constructed using laser triangulation (during this process, the industrial camera 406 positions the placement frame 2 using the positioning marker 201 to accommodate the slight offset and tilt of the placement frame 2 on the transmitting laser 1). The PLC controller 101 detects the flatness of the adhesive-backed product surface by combining the three-dimensional contour. This application can continuously place the placement frame 2 containing the adhesive-backed product onto the transmitting laser 1 to achieve assembly line inspection with high inspection efficiency.

[0053] Secondly, in this application, the height of the industrial camera 406 can be adjusted by the second cylinder 401, the angle of the rotating seat 405 and the industrial camera 406 can be adjusted by the support base 403, and the laser array 303 can be raised and lowered by the first cylinder 302 to adapt to different adhesive products. Only the placement frame 2 needs to be customized for production, so that this application has high adjustability and thus high applicability.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
