The described embodiments are only some embodiments of this utility model, not all embodiments.

[0033] 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 merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] refer to Figures 1 to 4 The battery cell testing equipment provided in this embodiment includes a ring-shaped worktable 1 and a rotating transfer mechanism 2 located at the center of the ring-shaped worktable 1. The ring-shaped worktable 1 is fixedly provided with a loading position 11, a unloading position 12 and a plurality of testing positions 13 along the circumferential direction. The loading position 11 and the unloading position 12 are opposite to each other, and the plurality of testing positions 13 are arranged between the loading position 11 and the unloading position 12.

[0036] The rotary transfer mechanism 2 includes a first transport component 21, a second transport component 22, and a first drive component 23. The first drive component 23 is provided with a first drive end 231 and a second drive end 232. The first transport component 21 is connected to the first drive end 231, and the second transport component 22 is connected to the second drive end 232. The first transport component 21 operates between the loading position 11 and the testing position 13, and the second transport component 22 operates between the testing position 13 and the unloading position 12. In some embodiments, the first drive component 23 can be configured to drive only the rotational movement of the first transport component 21 and the second transport component 22, or it can be configured to drive both the rotational movement and linear movement of the first transport component 21 and the second transport component 22.

[0037] It should be noted that in this embodiment, the center of the loading position 11 and the circular worktable 1 is on the same straight line as the unloading position 12, that is, the loading position 11 and the unloading position 12 are located on the same diameter of the circular worktable 1. The diameter of the loading position 11 and the unloading position 12 is the dividing line, and the test positions 13 are equally distributed on both sides of the dividing line, that is, the total number of test positions 13 is 2n. In this embodiment, n is 8. The test positions 13 located on the same side of the dividing line are equally spaced, and the test positions 13 on the circular worktable 1 are symmetrically distributed about the central axis of the circular worktable 1.

[0038] During the testing process, the battery cell assembly is first loaded onto the loading position 11 by manual labor or a loading mechanism. At this time, the first transport component 21 is located at the loading position 11, and the second transport component 22 is located at the unloading position 12. The first transport component 21 picks up the battery cell assembly from the loading position 11. The first drive component 23 drives the first transport component 21 to the test position 13. At this time, the second transport component 22 is also located at another test position 13. The first transport component 21 places the picked-up battery cell assembly onto its corresponding test position 13. At the same time, the second transport component 22 picks up the battery cell assembly that has completed testing at its corresponding test position 13. Afterward, the first drive component 23 drives the first transport component 21 back to the loading position 11 to continue picking up battery cell assemblies from the loading position 11. Meanwhile, the second transport component 22 also places the picked-up battery cell assembly onto the unloading position 12. Under the continuous drive of the first drive component 23, the first transport component 21 and the second transport component 22 can continuously perform test loading and test unloading operations, thereby realizing the continuous operation of the cell testing equipment and effectively improving the production efficiency of the battery.

[0039] In one embodiment, the first drive assembly 23 includes a rotary drive motor 233 and a linear mounting bracket 234. The drive end of the rotary drive motor 233 is connected to the center of the linear mounting bracket 234. A first drive member 235 and a second drive member 236 are disposed at opposite ends of the linear mounting bracket 234. A first drive end 231 is disposed on the first drive member 235, and a second drive end 232 is disposed on the second drive member 236. In this embodiment, the first drive member 235 and the second drive member 236 are used to drive the first conveying assembly 21 and the second conveying assembly 22 to move horizontally, respectively. Both the first drive member 235 and the second drive member 236 are linear drive modules.

[0040] By setting the first driving component 235 and the second driving component 236, when the first transport component 21 and the second transport component 22 grab or place the battery cell component, the first transport component 21 and the second transport component 22 can extend to the outer periphery of the linear mounting frame 234; when the first transport component 21 and the second transport component 22 rotate and move, the first transport component 21 and the second transport component 22 can be temporarily retracted into the interior of the linear mounting frame 234, so that the first transport component 21 and the second transport component 22 will not interfere with other mechanisms set on the ring worktable 1 during the rotation and movement, which is conducive to the normal operation of the battery cell testing equipment.

[0041] In one embodiment, the first conveying assembly 21 includes a first fixing member 211 and a third driving member 212 for driving the first fixing member 211 to move vertically, and the second conveying assembly 22 includes a second fixing member 221 and a fourth driving member 222 for driving the second fixing member 221 to move vertically. The third driving member 212 and the fourth driving member 222 can be a drive motor or a drive cylinder, and the first fixing member 211 and the second fixing member 221 can be a clamp, a suction cup, or a snap-fit ​​device, etc.

[0042] In this embodiment, both the first fixing member 211 and the second fixing member 221 are snap-fit ​​protrusions. The battery cell assembly loaded onto the loading position 11 includes a battery cell and a fixture. The battery cell is fixedly placed on the fixture, such as... Figure 4 As shown, the bottom of the fixture 100 is provided with a slot 101 with the opening of the slot 101 facing downward. The engaging protrusion can move vertically upward under the drive of the third driving member 212 or the fourth driving member 222 and engage in the slot 101 to fix the battery cell assembly. Then, by the drive of the first driving member 235 or the second driving member 236, the battery cell assembly can be pushed and pulled to realize the transportation of the battery cell assembly.

[0043] The battery cell testing equipment of this embodiment fixes the loading position, unloading position, and each testing position on a circular worktable. A first transport component transfers the battery cell assembly between the loading position and the testing position, and a second transport component transfers the battery cell assembly between the testing position and the unloading position. Under the continuous drive of a first drive component, the first and second transport components can continuously perform loading and unloading operations, respectively, achieving continuous operation of the battery cell testing equipment and effectively improving the efficiency of battery production. The cooperation of the rotary drive motor, the first drive component, and the second drive component prevents interference between the various mechanisms in the battery cell testing equipment, thereby ensuring the normal operation of the equipment.

The limiting barrier 31 can achieve the initial positioning of the battery cell assembly, while the pushing component 32 pushes the battery cell assembly against the limiting barrier 31 to achieve the final positioning and fixation, with high positioning accuracy. It should be noted that the limiting barrier 31 is not provided on the side of the test position 13 near the rotary transfer mechanism 2, thereby allowing the battery cell assembly to be pushed, pulled, and translated by the first transport component 21 or the second transport component 22.

[0046] In this embodiment, the pushing component 32 includes a horizontal driving cylinder and a pushing member that is driven and connected to the horizontal driving cylinder. The horizontal driving cylinder is fixedly mounted on the annular worktable 1. The part of the pushing member that is in contact with the battery cell assembly is provided with rollers.
