Embodiment approach
[0047] When the present invention detects the surface defects of the button battery 0201, firstly the feeding slide 0202 receives the produced button battery 0201, and under the action of gravity, the button battery 0201 enters the downwardly inclined first three-channel slide 0203 and the slideway 0204 in turn, The turntable device 0205 rotates and takes away the button batteries 0201 in the slideway 0204 in an orderly manner. The button batteries 0201 fall into the conveyor belt device 0206 through the hole disc 020503, and the previously adjusted conveyor belt device 0206 allows the button batteries 0201 to enter in a neat row. The last three-channel slide 0207, then enters the first three-channel conveyor belt 0304, the first coaxial light source camera 0305 and the first camera 0307 detect the negative electrode of the button battery 0201, and the detection result will be input into the computer 07, and then input into the controller 06, if a certain A button battery 0201 ...

The invention discloses an automatic button cell appearance detection system, which comprises a base, a synchronization module, a first detection module, a second detection module, a third detection module and a control system, and is characterized in that the heights of a first coaxial light source camera, a first camera and a first area light source in the first detection module are adjusted through a first telescopic rod; and high-quality button cell images are obtained, the images are input into a computer to judge whether defects exist or not, and the controller controls to remove the button cells with the defects. The first detection module and the third detection module are used for detecting the negative electrode and the positive electrode of the button cell respectively, and defects such as scratches, liquid leakage, stains and pits are detected; and the second detection module can detect the vertical face of the button cell. Compared with other button cell appearance defect detection devices, the button cell appearance defect detection device aims at the overall appearance of the button cell, various types of defects of the button cell are automatically detected, and the integrity of appearance detection of the button cell is guaranteed.
Description
technical field [0001] The invention relates to the technical field of product surface defect detection, in particular to a surface defect detection system for button batteries. Background technique [0002] Button batteries are commonly used energy storage devices. During the production process, the surface of the battery will have defects such as dirt, scratches, leakage, and dents due to friction and collision, which will affect the quality of the battery. In order to ensure the quality of the button battery Quality and safety, its surface defect detection has become an essential part of the production process. [0003] Patent No. CN103940584A discloses a button battery detection system, which adopts two reflective mirrors at an angle of 90 degrees, and achieves the purpose of single-camera multi-channel imaging through the reflection of the reflective mirrors. However, this detection method can only detect a single sample, and cannot realize the automatic detection requ...
