[0028] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see the attached Figure 1 The utility model provides a CCD detection mechanism with an external power supply, which can be used in CCD optical detection, such as battery cell CCD detection, to detect defects such as damage, leakage, electrode folding, edge sealing foreign matter, convex points, pinholes, dents, scratches, indentations, dirt, surface wrinkles, etc. on the surface of the battery cell 4, and can also measure the thickness of the battery cell 4.

[0032] The CCD detection mechanism of the external power supply of the present invention includes a turntable 1. In a preferred embodiment, the edge of the turntable 1 extends away from the axial center of the turntable 1 to form a plurality of detection areas 11. Specifically, there are four detection areas 11 so that the turntable 1 can accommodate multiple battery cells 4 to be detected. It can be understood that this is not a specific limitation on the number of detection areas 11, and technicians in related fields can make improvements or replacements on this basis.

[0033] The turntable 1 is provided with a CCD light source 2 in the detection area 11, and the CCD light source 2 is installed on the turntable 1. Specifically, there are several CCD light sources 2 in each detection area 11, and the several CCD light sources 2 are distributed at intervals and arranged in a ring along the edge of the turntable 1. As shown in some specific embodiments, each detection area 11 is provided with two CCD light sources 2, and several CCD light sources 2 perform CCD detection on the battery cell 4, which can improve the optical detection efficiency.

[0034] In a preferred embodiment, see the attached Figure 2 A clamp 22 is provided on one side of the CCD light source 2. The clamp 22 includes a pressure plate 221. The pressure plate 221 is located on the top of the CCD light source 2. The pressure plate 221 is transmission-connected to a clamping driver 222. During the detection process, the battery cell 4 to be detected is placed on the CCD light source 2. The clamping driver 222 drives the pressure plate 221 close to the CCD light source 2 and presses it on the surface of the battery cell 4 to be detected, so that the battery cell 4 to be detected is positioned. Among them, the clamping driver 222 is preferably, but not limited to, a clamping cylinder, and the output end of the clamping cylinder is transmission-connected to the clamping plate. The setting of the clamp 22 is conducive to reducing the possibility that the battery cell 4 to be detected will move arbitrarily during the detection process, which will affect the CCD detection result.

In a preferred embodiment, a plurality of external power supplies 32 are provided, and the plurality of external power supplies 32 are arranged in a ring along the edge of the turntable 1. When the turntable 1 drives the adapter 31 to rotate to the corresponding external power supply 32, the adapter 31 is connected to the external power supply 32. The external power supply 32 is connected to an external power source and supplies power to the CCD light source 2 through the adapter 31. The CCD light source 2 performs optical detection on the battery cell 4, and the operation is convenient.

[0036] During CCD testing of batteries, the battery cell 4 to be tested is placed on the CCD light source 2. The turntable 1 drives the adapter 31 to rotate and connect it to the external power supply 32. The external power supply 32 supplies power to the CCD light source 2 through the adapter 31, forming a closed circuit. The CCD light source 2 is routed separately through the power supply assembly 3. Compared with the centralized routing of cables in the center of the operating table in traditional CCD testing mechanisms, the cable routing is more orderly, which helps maintenance personnel quickly locate damaged cables, improves maintenance convenience, and facilitates the replacement of damaged cables.

The second positioning block 3222 is detachably connected to the second seat body 3221. Specifically, the second positioning block 3222 and the second seat body 3221 are assembled by bolts.

[0043] The second insulating base 322 is connected to a driver 323. The driver 323 is preferably, but not limited to, an external cylinder. The output end of the external cylinder is connected to the second base 3221 to drive the second probe 321 toward or away from the first probe 311.
