[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 ,Figure 2 , Figure 3 This is a schematic diagram of the structure of this patent. A back-side detection device for electroplated tin plate includes a base plate 1, a conveyor belt 2 and a detection camera 3. The conveyor belt 2 is installed on the upper wall of the base plate 1 and is electrically connected to an external power source. An electroplated tin plate 4 is placed on top of the conveyor belt 2. A fixing frame 5 is installed on the upper wall of the base plate 1 and a detection camera 3 is installed on the lower wall of the fixing frame 5.

[0022] The detection camera 3 proposed in this paper is connected to an external computer. The images it captures are transmitted to the computer, and then the image processing system in the computer detects the back of the electroplated tin board 4. Compared with manual detection, its detection efficiency and accuracy are greatly improved.

[0023] Positioning mechanisms 6 are installed on both the left and right side walls of the base plate 1. The positioning mechanism 6 includes a threaded hole 61, a screw 62, a limiting plate 63 and a buffer pad 64. The side wall of the base plate 1 has a threaded hole 61. The screw 62 is screwed into the threaded hole 61. The end of the screw 62 above the conveyor belt 2 is equipped with a limiting plate 63. The side wall of the limiting plate 63 is fitted with a buffer pad 64.

[0024] When the electroplated tin plate 3 is placed on the conveyor belt 2 with its back facing up, the conveyor belt 2 can drive the electroplated tin plate 4 to move forward. During its movement, the limiting plate 63 can adjust the electroplated tin plate 4 so that when it passes the detection camera 3, the electroplated tin plate 4 is located directly below the detection camera 3, thereby avoiding the situation where the back of the electroplated tin plate 4 cannot be fully captured, which would affect the final detection result.

[0025] The position of the limiting plate 63 in this device can be adjusted by rotating the screw 62, so that it can be used for different sizes of tin-plated plates 4, thereby improving the applicability of this device.

[0026] A connecting post 7 is installed on the side wall of the limiting plate 63. A connecting groove 8 is opened on the side wall of the connecting post 7. The screw 62 is inserted into the connecting groove 8 and can rotate within the connecting groove 8.

[0027] The screw 62 is set in the connecting groove 8, so when the screw 62 rotates, the limiting plate 63 will not rotate with the screw 62.

[0028] The limiting plate 63 is made of transparent acrylic material. The side wall of the limiting plate 63 is equipped with a lighting mechanism 9. The lighting mechanism 9 includes a slide groove 91, a sliding plate 92 and a light strip 93. The side wall of the limiting plate 63 is provided with a slide groove 91. The sliding plate 92 is slidably installed in the slide groove 91. The light strip 93 is fitted to the side wall of the sliding plate 92 and is electrically connected to an external power source.

[0029] The lighting mechanism 9 can illuminate the tin-plated plate 4, making the marks on the back of the tin-plated plate 4 more clearly and improving the detection accuracy of the device.

[0030] Meanwhile, the position of the lighting mechanism 9 in this device can be adjusted by sliding the sliding plate 92, so that it can be used with tin-plated plates 4 of different thicknesses;

[0031] The position of its light strip 93 should be slightly higher than the thickness of the electroplated tin plate 4.

[0032] A slider 10 is installed on the side wall of the sliding plate 92. The slider 10 is slidably installed in the slide groove 91. A rubber sleeve 11 is sleeved on the outside of the slider 10. The rubber sleeve 11 can fit against the inner wall of the slide groove 91.

[0033] By setting the rubber sleeve 11, the friction between the slider 10 and the groove 91 can be increased, so that the position of the sliding plate 92 will not change when there is no external force.

[0034] A dust cover 12 is fitted onto the outside of the detection camera 3.

[0035] A support rod 13 is installed on the inner wall of the dust cover 12, and a cleaning brush 14 is installed on the upper wall of the support rod 13. The cleaning brush 14 can fit against the lower wall of the detection camera 3.

[0036] By setting the cleaning brush 14, when it is necessary to clean the lens of the detection camera 3, the lens of the detection camera 3 can be cleaned by rotating the dust cover 12.

[0037] When this patent is in operation, the worker places the electroplated tin plate 3 with its back facing up on the conveyor belt 2. The conveyor belt 2 can drive the electroplated tin plate 4 forward. During its movement, the limiting plate 63 can adjust the electroplated tin plate 4 so that when it passes the detection camera 3, the electroplated tin plate 4 is located directly below the detection camera 3, thereby avoiding the situation where the back of the electroplated tin plate 4 cannot be fully captured, which would affect the final detection result.

[0038] The detection camera 3 will transmit the captured images to the computer, and then the image processing system in the computer will detect the back of the electroplated tin plate 4.
