Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a cylindrical battery appearance defect detection device. Background Art

[0002] Cylindrical batteries are batteries with high capacity, long cycle life and wide operating temperature range. The products are used in solar lamps, lawn lamps, backup energy, power tools, toy models, and photovoltaic energy. The outer shell of the cylindrical battery provides protection for its inner core. Before producing cylindrical batteries, the surface of the outer shell needs to be inspected to avoid defects on the surface of the outer shell that affect the service life of the cylindrical battery. The traditional inspection method is manual inspection, in which the staff inspects the surface of the outer shell with the naked eye. This inspection method is not only inefficient, but also has the problem of missed inspections. After searching, it was found that the application number "201721599370.7" discloses "a cylindrical battery appearance inspection device", which records "including a conveying device and a detection device, the detection device is arranged on the opposite sides and above the conveying device, and the conveying device is used to transport cylindrical batteries. And the cylindrical battery is made to rotate 360° when passing through the detection device, and the detection device is used to detect the appearance of the two end faces and the circumferential surface of the cylindrical battery. The above detection device allows the battery shell to rotate by itself, and takes pictures of the surface of the battery shell through a camera, so as to effectively detect the battery shell body, thereby improving the detection efficiency of the battery shell. However, the above detection device still has certain shortcomings when used: since the detection device is installed in the middle, when an unqualified battery shell is detected, the battery shell needs to be transported to the end through a conveying device for classification, and the staff is very likely to take the wrong battery shell while waiting for the unqualified shell to be transported to the end. Based on this, we propose a cylindrical battery appearance detection device that is more convenient to use. Utility Model Content

[0021] In this embodiment, the connecting assembly 16 includes two pushing cylinders 161 fixedly installed at the bottom end of the workbench 1 , the pushing cylinders 161 are fixedly connected to a connecting plate 162 , and the connecting plate 162 is fixedly connected to the bottom end of the connecting platform 12 .

[0022] Specifically, the connecting plate 162 is moved by pushing the cylinder 161, so that the connecting platform 12 is moved away from the workbench 1, and the battery shells are dropped between the two rollers 14, which makes it convenient for the staff to classify and place the tested battery shells.

[0023] In this embodiment, two fixed blocks 163 are fixedly connected to both sides of the bottom end of the connecting platform 12, and a guide rod 164 is fixedly connected to one side of the fixed block 163.

Light is used to improve the accuracy of shell detection. After the CCD camera 18 feeds back the shooting results to the terminal and compares them, the staff will know whether the battery shell is qualified or not. When the detection is completed, the pushing cylinder 161 drives the connecting platform 12 to move so that the battery shell passes between the two rollers 14 and falls to the surface of the third slide 21, which is convenient for the staff to classify and place the battery shells according to the test results. Compared with the comparison file, it is more convenient for the staff to use. After that, the pushing cylinder 161 drives the connecting platform 12 to return to its position, and the pushing cylinder 7 pushes out the next battery shell. Repeat the above steps to perform appearance inspection on the battery shell.
