[0002] ‌The main function of the rectifier bridge is to convert alternating current into direct current. It is composed of four diodes connected into a bridge circuit, ensuring that the current can only flow in one direction, thus realizing the conversion of alternating current to direct current. Before the rectifier bridge copper frame is welded with the diode, point gluing needs to be carried out at the corresponding position of the copper frame, and if the product point gluing is abnormal, it will cause problems such as failure of the product in the client application. Therefore, the current usually adopts image point gluing identification method to detect the point gluing state.

[0003] Image point gluing identification is to place the copper frame after point gluing on the bearing platform, and distinguish and identify by black and white; the bearing platform and the point gluing are both black in image detection, and the copper frame sheet is white, when the point gluing exceeds the frame sheet, the point gluing in the image is connected with the bearing platform, which causes the image to be unable to be identified. Therefore, developing a frame mirror image detection platform for improving the abnormal identification precision of point gluing is a technical problem to be solved by the case.
