Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a positioning device for processing lithium battery cells. Background Art

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the particularly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have particularly high requirements on the environment. With the development of science and technology, lithium batteries have now become mainstream.

[0003] The existing battery cell positioning device usually uses a separate cylinder to position and clamp the battery cell, which results in uneven clamping force on the battery cell, easily leading to positioning position deviation and affecting the processing accuracy of the battery cell.

[0004] In order to solve this problem, the present utility model is produced. Utility Model Content

[0007] Further improvements are: the sliding device includes a fixed block arranged to match the push rod, the positioning platform is rotatably provided with a rotating ring, the fixed block is arranged inside the rotating ring, the push rod is slidably passed through the fixed block, the inner wall of the rotating ring is provided with an inclined surface from the inside to the outside, the end of the push rod resists the inclined surface, and the positioning platform is provided with a rotating device for driving the rotating ring to rotate.

[0008] A further improvement is that the return device includes a return plate, the fixed block is provided with a sliding channel, the push rod passes through the sliding channel, the return plate is arranged on the push rod, and an elastic member is arranged in the sliding channel.

[0009] A further improvement is that the rotating device includes a gear, a gear groove is provided on the outer wall of the rotating ring, the gear is rotatably arranged on a positioning platform, the gear is meshed with the gear groove for transmission, and a driving device for driving the gear to rotate is provided on the positioning platform.

[0010] A further improvement is that the elastic member is a spring, the spring is sleeved on the push rod, one end of the spring resists the return plate, and the other end of the spring resists the inner wall of the sliding channel.

[0011] A further improvement is that the driving device is a servo motor.

[0012] A further improvement is that a rubber layer is provided on the clamping plate.

[0013] A further improvement is that: the clamping plates are four and arranged in a surrounding manner.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The structure is simple, convenient for clamping, and the clamping force is uniform, which reduces the generation of clamping errors. By rotating the ring and driving the push rod to slide at the same time, the battery cell can be clamped at the same time, so that the battery cell is clamped with uniform force, which is conducive to the clamping of the battery cell, reduces the generation of errors during clamping, and is conducive to the processing of the battery cell.

[0020] In order to protect the lithium battery during clamping, a rubber layer is provided on the clamping plate 4.

[0021] In order to enable more stable clamping, four clamping plates 4 are arranged in a surrounding manner.

[0022] Working principle:

[0023] When in use, when the lithium battery is to be clamped, the servo motor rotates, driving the gear 3 to rotate, the gear 3 meshes with the gear groove for transmission, driving the rotating ring 2 to rotate, and under the action of the inclined surface 6, the four push rods 5 are pushed to slide toward the lithium battery at the same time, thereby driving the clamping plate 4 to position the lithium battery in four directions at the same time, and the spring 9 is stretched. When the lithium battery is to be released, the servo motor reverses, driving the rotating ring 2 to reverse, and the spring 9 releases the elastic force, so that the push rod 5 returns to its position, driving the clamping plate 4 to return to its position, thereby releasing the clamping of the lithium battery.
