[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Example

[0023] In order to solve the above technical problems, this embodiment provides a battery appearance inspection device, such as Figure 1 As shown, it includes a loading component 10 and a transmission component 20 for conveying battery cells, and a first detection component 30, a second detection component 40 and a third detection component 50 which are sequentially arranged on the conveying path of the transmission component 20 along the conveying direction. The battery cells are automatically loaded by the loading component 10. After the battery cells are transferred to the transmission component 20, the battery cells are sequentially transmitted to the first detection component 30, the second detection component 40 and the third detection component 50 by the transmission component 20. The top surface and two opposite side surfaces of the battery cell are detected by the first detection component 30, the other two opposite side surfaces of the battery cell are detected by the second detection component 40, and the bottom surface of the battery cell is detected by the third detection component 50, thereby automatically detecting appearance defects on each surface of the battery cell, thereby improving the degree of automation, thereby improving the detection efficiency, and meeting the current increasingly efficient production mode.

[0024] Specifically, it also includes a robot 60 for transferring cells between the loading component 10 and the transmission component 20, and between the transmission component 20 and the third detection component 50. After the loading component 10 loads the cells, the robot 60 transfers the cells to the transmission component 20, and then the transmission component 20 sequentially transfers the cells to the first detection component 30, the second detection component 40, and the third detection component 50 for multi-faceted appearance inspection, and automatic inspection improves production efficiency.

[0025] Furthermore, in order to realize the transmission of battery cells, such as Figure 2As shown, the transmission component 20 includes a support frame 21, a driving component 22 for driving the support frame 21 to move back and forth along the conveying direction, and a lifting drive 25 for lifting the support frame 21 and the driving component 22. The support frame 21 is provided with a plurality of bearing platforms 23. The lifting drive 25 drives the support frame 21 to move up and down, so that the bearing platform 23 is lifted and carried on the battery cell. Then, the driving component 22 drives the lifting drive 25 and the support frame 21 to move back and forth along the conveying direction, thereby realizing the conveying of the battery cell forward. After the battery cell moves to the corresponding inspection station, the lifting drive 25 drives the support frame 21 to descend, so that the battery cell is placed on the inspection platform of the inspection station, and then the appearance of the battery cell is inspected by the first inspection component 30. Among them, a clamping component 26 is provided on each bearing platform 23, and the clamping component 26 can be composed of a clamp driven by a cylinder, so as to grasp and fix the battery cell during transfer.

[0026] Specifically, in the above scheme, the driving component 22 can be a motor and a screw rod structure, the driving component 22 is arranged on the bottom plate of the frame, a sliding plate 27 is slidably arranged on the bottom plate, the support frame 21 can be raised and lowered and slidably connected to both sides of the sliding plate 27, the lifting drive 25 can be a cylinder arranged on the sliding plate 27, and then the telescopic end of the lifting drive 25 is connected to the support frame 21, the driving component 22 drives the sliding plate 27 to move back and forth along the conveying direction, thereby driving the battery cell to be conveyed and moved.

[0027] Furthermore, after the first detection component 30 completes the detection of the top surface and two opposite side surfaces of the battery cell, the battery cell is transferred to the second detection component 40 through the transmission component 20. At this time, the battery cell needs to be rotated to detect the other two opposite side surfaces. For this purpose, the support frame 21 is also provided with a rotating component 24 for driving at least one supporting platform 23 to rotate. Preferably, there are three supporting platforms 23, and the supporting platform 23 in the middle is arranged on the rotating component 24. When the battery cell is transferred to the second detection component 40, the rotating component 24 drives the supporting platform 23 to rotate 90°, and then the second detection component 40 detects the other two opposite side surfaces of the battery cell. Among them, as Figure 3-4 As shown, the second detection component 40 includes a moving frame 41 located on both sides of the transmission component 20, a second visual detector 42 arranged on the moving frame 41, and a second driver 43 for driving the moving frame 41 to approach or move away from the transmission component 20. The second driver 43 can adopt a combined structure of a motor and a lead screw, so that the distance between the second visual detector 42 and the battery cell can be automatically adjusted, and then the focus is automatically completed before taking pictures.

[0028] Further, such as Figure 3As shown, the first detection component 30 includes a mounting frame 31 mounted above the transmission component 20, and first visual detectors 32 are respectively arranged on the top and opposite sides of the mounting frame 31. Three first visual detectors 32 are arranged to respectively perform photographic detection on the top surface and two opposite sides of the battery cell.

[0029] In the above scheme, an adjustment component 33 is also included for installing each first visual detector 32, and the adjustment component 33 drives the first visual detector 32 to approach or move away from the transmission component 20. The distance between the first visual detector 32 and the battery cell is automatically adjusted by the adjustment component 33, so as to automatically complete the focus before taking pictures.

[0030] Further, such as Figure 5 As shown, the adjustment assembly 33 includes a mounting seat 331, a slider 332 slidably disposed on the mounting seat 331, and a first driver 333 driving the slider 332 to move, and the first visual detector 32 is mounted on the slider 332. In some embodiments, the first driver 333 can be a combination of a motor and a lead screw. The position of the slider 332 on the mounting seat 331 is adjusted by the first driver 333, thereby achieving the purpose of adjusting the focal length of the first visual detector 32.

[0031] Furthermore, when the second inspection component 40 completes the inspection of the battery cell, the gripper of the robot 60 grabs the battery cell on the workstation of the second inspection component 40 and transfers it to the top of the third inspection component 50. The third inspection component 50 is a third visual detector embedded in the frame. After the battery cell is transferred to the top of the third inspection component 50, the bottom surface of the battery cell is photographed by the third inspection component 50 to complete the inspection.

[0032] The battery cell needs to be positioned before loading. Figure 6 As shown, a positioning assembly 11 is also provided at the end of the feeding assembly 10. The feeding assembly 10 is a feeding conveyor belt. When the battery cell is conveyed to the end, it is positioned by the positioning assembly 11. The positioning assembly 11 may be composed of a cylinder and a positioning block.

[0033] It also includes a feed conveyor belt 70 disposed on one side of the third detection component 50. In the above scheme, after the third detection component 50 completes the detection, the gripper of the robot 60 transfers the inspected battery cell to the feed conveyor belt 70, and then the battery cell is transported to the next production process through the feed conveyor belt 70, thereby completing the fully automatic appearance inspection production and improving the inspection efficiency. In order to improve efficiency, multiple sets of battery cell appearance inspection equipment of the present application can be arranged side by side to increase production capacity.

[0034] To summarize, the present application scheme sets up a loading component and a transmission component for conveying battery cells, and automatically loads the battery cells through the loading component in the first detection component, the second detection component, and the third detection component in the conveying path of the transmission component. After the battery cells are transferred to the transmission component, the battery cells are sequentially transmitted to the first detection component, the second detection component, and the third detection component through the transmission component. The first detection component detects the top surface and two opposite side surfaces of the battery cell, the second detection component detects the other two opposite side surfaces of the battery cell, and the third detection component detects the bottom surface of the battery cell, thereby automatically performing appearance inspection on each surface of the battery cell, thereby improving the degree of automation, thereby improving the detection efficiency, and meeting the current increasingly efficient production model.

[0035] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
