[0002] Lead-free tin bar is a lead-free tin alloy bar, usually made of tin, copper, zinc and other metal alloys. Lead-free tin bar is widely used because it does not contain lead, especially in the field of electronic manufacturing and welding. The use of lead-free tin bar can effectively reduce the emission of harmful substances and meet environmental protection requirements. In addition, lead-free tin bar also has a higher melting point and better welding performance.

[0003] After the lead-free tin bar is finished, its surface needs to be inspected for damage, so a damage detection device is needed. Although the traditional damage detection device has detection capabilities, it still has some shortcomings. For example, its ability to fix lead-free tin bars of different specifications is poor. Therefore, when performing damage inspection on it, it is easy for the lead-free tin bar to shift or fall, thereby affecting its normal damage detection. Therefore, a surface damage detection device for lead-free tin bar finished products is proposed to address the above problems. Utility Model Content

A movable block 6 is fixedly connected to the center of the bottom wall of the fixed splint 4. The fixed splint 4 is slidably connected to the movable groove 5 through the movable block 6. The front and rear sides of the fixed splint 4 are symmetrical and fixedly connected with a connecting rod 7.

Therefore, it is not easy to cause the lead-free tin bar to shift or fall when performing damage inspection on it, thereby ensuring its normal damage inspection; the detection assembly includes a detector 14 fixedly connected to the end of the mounting bracket 13 away from the inner top wall of the casing 2, and a camera 15 is provided under the detector 14.

[0023] Workflow: The lead-free solder bar needs to be fixed and clamped before testing. When fixing and clamping, firstly, the spacing of the clamping components needs to be adjusted according to the length specification of the lead-free solder bar to be tested. It can be done by moving the movable block 6 in the movable slot 5. When clamping, firstly, the movable rod 9 is pulled upward by the pull handle 10, and the movable rod 9 drives the movable clamping plate 11 to move upward to increase the spacing between the movable clamping plate 11 and the fixed clamping plate 4. Then, the lead-free solder bar is placed between the fixed clamping plate 4 and the movable clamping plate 11, and then the pull handle 10 is released. 10 will squeeze the fastening spring 12 when driving the movable clamp 11 to move upward. Therefore, after releasing the pull handle 10, the fastening spring 12 will drive the movable clamp 11 to reset through its own resilience, that is, the lead-free tin bar is fixed and clamped. After the lead-free tin bar is fixed, the high-resolution image of the surface of the lead-free tin bar is captured by the camera 15, and these images are transmitted to the detector 14 for analysis. The detector 14 can use various algorithms to detect damage or defects and display the results on the screen of the detector 14.
