Description

Technical Field

[0001] The present invention relates to the technical field of product surface defect detection, and in particular to a surface defect detection system for button batteries. Background Art

[0002] Button batteries are commonly used energy storage devices. During their production process, the surface of the battery may produce defects such as dirt, scratches, leakage, and dents due to friction and collision, which affect the quality of the battery. In order to ensure the quality and safety of button batteries, surface defect detection has become an indispensable part of the production process.

[0003] Patent number CN103940584A discloses a button battery inspection system that uses two mirrors at a 90-degree angle to achieve multi-channel imaging with a single camera. However, this inspection method can only test a single sample and cannot achieve the automated inspection required by industrial production.

[0004] Patent number CN110108710A discloses a device and method for detecting pits on the positive electrode of button batteries. This device incorporates a camera, lens, annular light source, and a reflective grating into an imaging system. This method prevents interference from the font on the button battery's font on pit detection, and also prevents interference from the font on pit detection. However, this device fixes the camera, lens, annular light source, and reflective grating together, making it difficult to adjust the positions of the components and affecting the images captured for button batteries of different sizes. Furthermore, this device only detects pits on the positive electrode and cannot fully detect button batteries, nor can it be automated.

[0005] Patent number CN112024422A discloses a button battery surface defect detection system, which includes: a positive electrode pitting detection station, a deep scratch detection station, a shallow scratch detection station, a negative electrode pitting detection station, a wire detection station, a green mold scratch detection station, a dirt detection station, a kicking device, a turning device, and a conveyor belt. This system is a method-based system. While theoretically capable of automatically detecting most defects on the front and back of button batteries, the use of seven stations to capture button battery images increases costs and does not account for potential defects on the button battery's facade.

[0006] During the button battery inspection process, it is necessary not only to consider various defects such as dirt, scratches, leakage, and dents on the positive and negative electrodes, but also the possibility of defects on the facade. At the same time, efficiency should be improved and automation should be achieved. Therefore, it is very meaningful to design an automated system that can inspect the overall appearance of button batteries. Summary of the Invention

The third rotating slide 0506 is fixed by the third oblique rod 0510, the third partition plate 0507 and the third support rod 0513, and is tilted to the lower right. The third rotating slide 0506 is controlled by the electrical signal of the controller 06 and is equipped with a sensing device; the third waste box 0509 and the finished product box 0508 are located directly below the third rotating slide 0506.

[0042] like Figure 8 As shown, the first coaxial light source camera 0305, the first camera 0307, ​​the second coaxial light source camera 0403, the third coaxial light source camera 0504, and the third camera 0505 are connected to the computer 07 to output the detection situation; the computer 07 is connected to the controller 06, and the controller 06 controls the movement of the first rotating slide 0308, the paddle 0409, and the third rotating slide 0506 according to the detection situation; the controller 06 can manually adjust the speed of the synchronous motor 0209, the motor 020604, the first motor 0302, the second motor 0407, and the third motor 0501 according to the actual production situation.

[0043] In the present invention, there is a baffle on the left side below the curved three-dimensional pipe 0401, paddles 0409 on the front and back, and a gap on the right side. The lower ends of the baffle and paddle 0409 are at a certain distance from the second three-channel conveyor belt 0402, so as to ensure that the button battery 0201 can stand on the second three-channel conveyor belt 0402. When the second coaxial light source camera 0403 detects the vertical surface of the button battery 0201, it sends a signal, and the controller 06 controls the second three-channel conveyor belt 0402 to rotate to the left to drive the button battery 0201 to rotate, and then detect the vertical surface of the button battery 0201. After that, the second three-channel conveyor belt 0402 stops, the paddle 0409 puts the button battery 0201 down, and the second three-channel conveyor belt 0402 rotates to the right to transport the button battery 0201 to the third detection module 05.

[0044] In the present invention, before the button battery 0201 enters the curved three-dimensional pipe 0401, the negative pole faces upward. After entering the curved three-dimensional pipe 0401, the vertical surface of the button battery 0201 is along the front-to-back direction. The interiors of the three curved three-dimensional pipes 0401 are twisted 90 degrees in the same direction, so that when the button battery 0201 reaches the exit, the vertical surface is along the left-right direction. The three pairs of paddles 0409 paddle the button battery 0201 in the same direction, thereby ensuring that the same button battery 0201 is detected as positive in the third detection module 05 when the negative pole is detected by the first detection module 03, and vice versa.

[0045] In the present invention, the size of the button battery 0201 is not fixed. The system can adjust the size of related components according to the size of the button battery 0201 to be detected to achieve the purpose of detection.

[0046] Preferred embodiment:

[0047] When inspecting the surface defects of button batteries 0201, the present invention firstly receives the produced button batteries 0201 on the loading slide 0202. Under the action of gravity, the button batteries 0201 sequentially enter the downwardly inclined front three-channel slide 0203 and the slide 0204. The turntable device 0205 rotates, orderly carrying away the button batteries 0201 in the slide 0204. The button batteries 0201 fall into the conveyor device 0206 through the hole disc 020503. The pre-adjusted conveyor device 0206 allows the button batteries 0201 to enter the rear three-channel slide 0207 in an orderly manner. Then it enters the first three-channel conveyor belt 0304, and the first coaxial light source camera 0305 and the first camera 0307 detect the negative electrode of the button battery 0201. The detection result will be input into the computer 07 and then into the controller 06. If a button battery 0201 has a defect, the controller 06 will control the corresponding first rotating slide 0308 to rotate, so that the button battery 0201 with the defect falls into the first waste box 0310. The first rotating slide 0308 has a sensing device, which automatically resets when it senses that a button battery 0201 has fallen. The button battery 0201 without defects will be moved along the first rotating slide. The slide 0308 enters the curved three-dimensional pipe 0401 and stands on the second three-channel conveyor belt 0402. The second coaxial light source camera 0403 detects the vertical surface of the button battery 0201 and inputs the signal into the computer 07 and then into the controller 06. The controller 06 controls the second motor 0407 to rotate to the left for a certain distance to ensure that the vertical surface of the button battery 0201 can rotate one circle. If the vertical surface of the button battery 0201 is detected to have a defect, the controller 06 controls the third rotating slide 0506 to rotate, and then the second motor 0407 stops. The controller 06 controls the paddle 0409 to put down the button battery Pool 0201, the second motor 0407 rotates right again, and the button battery 0201 enters the third three-channel conveyor belt 0503. The third coaxial light source camera 0504 and the third camera 0505 detect the positive electrode of the button battery 0201. If the button battery 0201 is detected to have defects, the controller 06 controls the third rotating slide 0506 to rotate to remove the defective button battery 0201. The third waste box 0509 is used to collect the button batteries 0201 from the second inspection module 04 and the third inspection module 05. The button batteries 0201 with intact surfaces finally enter the finished product box 0508.
