Description

Technical Field

[0001] This utility model belongs to the field of battery appearance inspection technology, specifically relating to a multi-angle appearance inspection device for lithium-ion batteries. Background Technology

[0002] With the rapid development of electronic devices, lithium-ion batteries, as their core power source, have seen explosive growth in market demand. In the production process of lithium-ion batteries, appearance quality is one of the important indicators for measuring battery quality. Minor defects in the battery appearance, such as scratches, dents, bulges, and cracks, can affect the battery's performance, safety, and lifespan. Therefore, comprehensive and accurate inspection of the appearance of lithium-ion batteries is a key step in ensuring battery quality during the production process.

[0003] However, since square lithium-ion batteries have six sides, all six sides need to be inspected during the testing process. Current testing devices have difficulty inspecting the bottom of the battery, and usually require the lithium-ion battery to be flipped over for inspection, which is cumbersome, reduces the testing speed, and causes more trouble for the testing work. To address this problem, the applicant proposes a multi-angle inspection device for the appearance of lithium-ion batteries. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle inspection device for the appearance of lithium-ion batteries. This device can inspect the bottom of the lithium-ion battery body during the transport process without requiring the battery body to be flipped. It can perform a comprehensive inspection of all six sides of the lithium-ion battery body during the transport process, effectively simplifying the operation process, improving the inspection speed, and bringing more convenience to the inspection work.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-angle appearance inspection device for lithium-ion batteries includes:

[0007] A conveying mechanism and a carrying mechanism and a detection mechanism respectively mounted on the top of the conveying mechanism;

[0008] The conveying mechanism includes a worktable, on the top of which are symmetrically distributed rotating wheels, and a conveyor belt is driven between the rotating wheels.

[0009] The carrying mechanism includes a support seat hinged to the top of the conveyor belt, a limit frame slidably mounted on the top of the support seat, a lithium-ion battery body placed inside the limit frame, and a roller rotatably mounted on the front end of the limit frame.

[0010] The testing mechanism includes a first testing frame, a second testing frame, and a third testing frame, which are respectively fixedly installed on the top of the workbench. The third testing frame has a lifting track frame corresponding to the rollers fixedly installed inside.

[0011] Preferably, the inner wall of the first detection frame is fixedly equipped with a first image acquisition camera that is symmetrically distributed, and the inner wall of the second detection frame is fixedly equipped with a second image acquisition camera that is symmetrically distributed.

[0012] Preferably, a third image acquisition camera is fixedly installed on the inner side of the third detection frame, and the third image acquisition camera is located at the top and bottom of the lifting track frame.

[0013] Preferably, a support frame is fixedly installed on the top of the workbench, and a display is fixedly installed on the front end of the support frame.

[0014] Preferably, a motor is fixedly installed at the bottom of the workbench, and the output end of the motor is fixedly connected to the rotary wheel.

[0015] Preferably, the bottom of the workbench is fixedly equipped with support legs, and a crossbar is fixedly installed between the support legs.

[0016] Preferably, the support base and the conveyor belt are hinged together by a rotating shaft, and the limiting frame and the support base are slidably installed together by a sliding rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model is equipped with a carrier mechanism and a detection mechanism that cooperate with each other. When the support base is moved to the lifting track frame, the limiting frame can move upward along the lifting track frame, which can automatically lift the lithium-ion battery body. This allows the third image acquisition camera to be placed at the bottom and top of the lithium-ion battery body, which can facilitate simultaneous detection of the bottom and top of the lithium-ion battery body. In conjunction with the first detection frame and the second detection frame, the periphery of the lithium-ion battery body can be detected. This can effectively cover the six sides of the lithium-ion battery body, enabling rapid and comprehensive detection without the need to flip the lithium-ion battery body. This effectively simplifies the operation process, improves the detection speed, and brings more convenience to the detection work.

[0019] (2) The limiting frame of this utility model is equipped with rollers. When it is conveyed to the lifting track frame, one end of the lifting track frame can be inserted into the bottom of the rollers. Through the rolling action of the rollers, the limiting frame can be easily lifted along the lifting track frame. After the limiting frame passes the lifting track frame, it can slowly descend along the other end of the lifting track frame to reset. This effectively ensures that the lithium-ion battery body is not prone to shaking and falling. Attached Figure Description

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a multi-angle appearance inspection device for lithium-ion batteries includes:

[0031] The conveying mechanism 2 and the carrying mechanism 3 and the detection mechanism 1 respectively mounted on the top of the conveying mechanism 2;

[0032] The conveying mechanism 2 includes a worktable 21, on the top of which are symmetrically distributed rotating wheels 23 are rotatably mounted, and a conveyor belt 24 is installed between the rotating wheels 23 for transmission.

[0033] The transport mechanism 3 includes a support base 33 hinged to the top of the conveyor belt 24. A limit frame 31 is slidably mounted on the top of the support base 33. A lithium-ion battery body 36 is placed inside the limit frame 31. A roller 32 is rotatably mounted on the front end of the limit frame 31.

[0034] The testing mechanism 1 includes a first testing frame 11, a second testing frame 13 and a third testing frame 15, which are respectively fixedly installed on the top of the workbench 21. The third testing frame 15 has a lifting track frame 17 corresponding to the roller 32 fixedly installed inside.

[0035] As can be seen from the above, when in use, the lithium-ion battery body 36 to be tested is placed on the limiting frame 31. The limiting frame 31 can support the lithium-ion battery body 36. The rotation of the rotating wheel 23 can drive the conveyor belt 24 to rotate, which can facilitate the transmission of the lithium-ion battery body 36. When the lithium-ion battery body 36 is transmitted to the first detection frame 11, the carrying mechanism 3 can follow the circular trajectory of the rotating wheel 23 and rotate horizontally by 90°. The first detection frame 11 can facilitate the simultaneous scanning and detection of the two narrower side walls of the lithium-ion battery body 36. As the carrying mechanism 3 continues to be transmitted with the conveyor belt 24, the carrying mechanism 3 can rotate horizontally by 90°, so that the lithium-ion battery body 36 can return to a horizontal state. When passing the second detection frame 13, the two wider side walls of the lithium-ion battery body 36 can be scanned and detected simultaneously.

[0036] When the carrier mechanism 3 moves to the third inspection frame 15, one end of the lifting track frame 17 extends to the bottom of the roller 32. The roller 32, following the rolling action of the lifting track frame 17, allows the limiting frame 31 to move upwards. This facilitates the extension of the third inspection frame 15 to the bottom and top of the lithium-ion battery body 36, enabling simultaneous scanning and inspection of the bottom and top of the lithium-ion battery body 36. This effectively covers all six sides of the lithium-ion battery body 36, allowing for rapid and comprehensive inspection without the need to flip the lithium-ion battery body 36. This simplifies the operation, increases inspection speed, and brings greater convenience to the inspection work. After passing over the lifting track frame 17 via the limiting frame 31, the frame slowly descends along the other end of the lifting track frame 17 to reset, effectively preventing the lithium-ion battery body 36 from shaking and falling.

[0037] Depend on Figure 5 It can be seen that the inner wall of the first inspection frame 11 is fixedly installed with a first image acquisition camera 12 that is symmetrically distributed, and the inner wall of the second inspection frame 13 is fixedly installed with a second image acquisition camera 14 that is symmetrically distributed.

[0038] As can be seen from the above, the first image acquisition camera 12 can conveniently take pictures of the two narrower sidewalls of the lithium-ion battery body 36 in the first inspection frame 11 at the same time, and the second image acquisition camera 14 can conveniently take pictures of the two wider sidewalls of the lithium-ion battery body 36 in the second inspection frame 13 at the same time, thus completing the inspection operation of the four outer surfaces of the lithium-ion battery body 36.

[0039] For details, please refer to Figure 5 As shown, a third image acquisition camera 16 is fixedly installed on the inner side of the third detection frame 15. The third image acquisition camera 16 is located at the top and bottom of the lifting track frame 17.

[0040] As can be seen from the above, the third image acquisition camera 16 can easily take pictures of the top and bottom of the lithium-ion battery body 36, and can easily complete the detection operation of the six sides of the lithium-ion battery body 36.

[0041] For details, please refer to Figure 2 As shown, a support frame 25 is fixedly installed on the top of the workbench 21, and a display 26 is fixedly installed on the front end of the support frame 25.

[0042] As can be seen from the above, the support frame 25 can be used to easily install multiple displays 26 according to usage requirements. The displays 26 can easily display images of the appearance inspection of the lithium-ion battery body 36, allowing staff to observe the inspection situation more intuitively.

[0043] Example 2:

[0044] refer to Figure 3 As shown, a motor 27 is fixedly installed at the bottom of the workbench 21, and the output end of the motor 27 is fixedly connected to the rotary wheel 23.

[0045] As can be seen from the above, the motor 27 can easily provide power to the rotating wheel 23, which can drive the rotating wheel 23 to rotate, and conveniently drive the conveyor belt 24 to rotate.

[0046] refer to Figure 2 As shown, a support leg 22 is fixedly installed at the bottom of the workbench 21, and a crossbar is fixedly installed between the support legs 22.

[0047] As can be seen from the above, the support leg 22 can provide stable support for the workbench 21, and the device can be placed in a suitable position to perform appearance inspection on the lithium-ion battery body 36.

[0048] refer to Figure 4 As shown, the support base 33 and the conveyor belt 24 are hinged together by a rotating shaft 34, and the limit frame 31 and the support base 33 are slidably installed together by a sliding rod 35.

[0049] As can be seen from the above, when the support seat 33 is conveyed to the corner by the conveyor belt 24, the rotating shaft 34 can be used to make corresponding rotational movements, so that the support seat 33 can easily pass through the corner position of the conveyor belt 24. The slide bar 35 can make the support seat 33 slide up and down, which can ensure that the support seat 33 is not easily tilted.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
