[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 、 Figure 2 、 Figure 4 As an embodiment provided by the present invention: An automatic lithium battery testing machine includes a tester 1 that can test the lithium battery 2. A carrier for providing support is provided at the top of the tester 1. A lithium battery 2 is provided at the top of the carrier. A stabilizing assembly is provided on the outer side of the lithium battery 2 near the top of the carrier. The stabilizing assembly includes a stabilizing block 3 that can limit the lithium battery 2 and a disc 32 that drives the movement of the stabilizing block 3. Multiple groups of stabilizing blocks 3 are provided. A limiting assembly is provided at the top of the tester 1. A connecting block 33 that drives the movement of the stabilizing block 3 is fixedly connected to the bottom end of the stabilizing block 3. A guide plate 34 that drives the movement of the connecting block 33 is fixedly connected to the left side of the connecting block 33. A circular groove 312 for sliding the limit rod 37 into the circular groove 312 to limit the disc 32 is provided at the bottom end of the disc 32. The limiting assembly includes a limit rod 37 that slides into the circular groove 312 to limit the disc 32. The disc 32 can rotate to the right. When the limit rod 37 slides into the circular groove 312, the disc 32 can be rotated and limited to the left. The limit rod 37 slides on the inner wall of the circular groove 312. A chute 35 for providing the movement of the pushing block 31 is provided on the front surface of the tester 1. A pushing block 31 that drives the movement of the limit rod 37 is slidably connected to the inner wall of the chute 35. The limit rod 37 is fixedly connected to the top end of the pushing block 31. The limit rod 37 penetrates and is slidably connected to the top of the tester 1.

[0034] Further, there are two sets of the guide plate 34, the arc-shaped groove 39, and the guide rod 38. The two sets of the guide plate 34, the arc-shaped groove 39, and the guide rod 38 are symmetrically arranged with the center line of the disc 32 as the axis of symmetry, which can stably drive multiple sets of the stabilizing blocks 3 to move to limit the lithium battery 2. There are multiple sets of the connecting block 33, the guide block 4, and the stabilizing block 3. The multiple sets of the connecting block 33, the guide block 4, and the stabilizing block 3 are symmetrically arranged with the disc 32 as the axis of symmetry. By setting multiple sets, the lithium battery 2 can be stably limited in the middle position.

[0035] Refer to Figure 1 - Figure 3 , a positioning component is arranged on the left side of the stabilizing block 3. The positioning component includes a guide block 4 that pushes the lithium battery 2 to be positioned in the middle. The guide block 4 is fixedly connected to the left side of the stabilizing block 3.

[0036] Refer to Figure 1 , Figure 3 , Figure 4 , the bottom end of the guide plate 34 is fixedly connected with a guide rod 38 that drives the guide plate 34 to move. An arc-shaped groove 39 for squeezing the guide rod 38 to move inward is formed at the top end of the disc 32. The arc-shaped groove 39 is set in an arc shape. By setting the arc-shaped groove 39 in an arc shape, the arc shape can squeeze the guide rod 38 to push the guide rod 38 to move inward. The guide plate 34 is slidably connected to the bottom end of the carrier. The connecting block 33 penetrates and is slidably connected to the right side of the carrier. The middle part of the disc 32 is fixedly connected with a rotating rod 310 that supports the disc 32. The rotating rod 310 is rotatably connected to the bottom end of the carrier, and the rotating rod 310 is rotatably connected to the top end of the tester 1.

[0037] Refer to Figure 2 - Figure 4 , the disc 32 and the carrier are elastically connected by a torsion spring 311. One end of the torsion spring 311 is fixedly connected to the bottom end of the carrier, and the other end of the torsion spring 311 is fixedly connected to the top end of the disc 32. The torsion spring 311 is sleeved on the outer wall of the rotating rod 310. By rotating the disc 32, the stabilizing block 3 is driven to move inward to limit the lithium battery 2. At the same time, the disc 32 rotates to squeeze the torsion spring 311. The reverse acting force of the squeezed torsion spring 311 can make the stabilizing block 3 quickly reset, thereby improving the quickness of releasing the limit on the lithium battery 2 and improving the test efficiency. The dial 31 and the tester 1 are elastically connected by a spring 36. One end of the spring 36 is fixedly connected to the inner wall of the bottom end of the chute 35, and the other end of the spring 36 is fixedly connected to the bottom end of the dial 31. By moving the dial 31 downward, the limiting rod 37 can be driven to move downward and slide out of the circular groove 312, so that the disc 32 can be released from the limit.

[0038] Furthermore, the left side of the top end of the limiting rod 37 is set as an inclined surface. By setting the left side of the top end of the limiting rod 37 as an inclined surface, when the rotating disk 32 drives the stabilizing block 3 to move inward, the disk 32 can squeeze the inclined surface of the limiting rod 37, causing the limiting rod 37 to move downward and drive the dial block 31 to move downward to squeeze the spring 36. When the stabilizing block 3 limits the lithium battery 2, the dial block 31 can be squeezed by the reverse acting force of the squeezed spring 36, causing the dial block 31 to reset and drive the limiting rod 37 to reset and slide into the circular groove 312 to limit the disk 32. Thus, the lithium battery 2 can be stably limited, preventing loosening, improving the fixing effect and stability of the lithium battery 2, enabling the lithium battery 2 to be in a relatively stable and safe state on the carrier, and ensuring the safety and reliability of the lithium battery 2 during testing.

[0039] Refer to Figure 1 , Figure 3

[0040] Working principle: When in use, after placing the lithium battery 2 above the carrier, rotate the disk 32 to drive the arc-shaped groove 39 to rotate. Since the arc-shaped groove 39 is arc-shaped, it squeezes the guide rod 38 to move inward, driving the guide plate 34, connecting block 33, and stabilizing block 3 to move inward. After the guide block 4 contacts the lithium battery 2, the inclined surfaces of multiple guide blocks 4 are used to push the lithium battery 2, positioning the lithium battery 2 at the central position. At the same time, since the rotation of the disk 32 drives the circular groove 312 to rotate, the circular groove 312 and the disk 32 squeeze the inclined surface of the limiting rod 37, causing the limiting rod 37 to move downward and drive the dial block 31 to move and squeeze the spring 36. At this time, after multiple stabilizing blocks 3 move to contact the lithium battery 2, with the reverse acting force of the squeezed spring 36, the limiting rod 37 is driven to slide into the circular groove 312 to limit the disk 32. Thus, the guide rod 38, guide plate 34, connecting block 33, and stabilizing block 3 can be limited, and the lithium battery 2 can be stably fixed above the carrier. At this time, it can prevent the lithium battery 2 from displacing or even having the risk of slipping on the carrier due to slight shaking or vibration during testing, improving the fixing effect and stability of the lithium battery 2, enabling the lithium battery 2 to be in a relatively stable and safe state on the carrier, and ensuring the safety and reliability of the lithium battery 2 during testing.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
