In the automatic production process of lithium battery, the carrying, positioning and clamping of the battery cell are the key processes, which directly affect the assembly accuracy and production rhythm of the battery. At present, part of the automatic clamp adopts pneumatic or electric drive to directly control the opening and closing of the clamping jaw. Although it can realize automatic clamping, it depends on external power (such as air cylinder or motor) to maintain clamping state, which increases energy consumption, and the structure is complex, and the production cost is high. SUMMARY

[0003] The utility model aims at providing a battery clamp for automation production with simple structure, which can realize fast and accurate clamping of the battery cell in the automatic production line, and reduce energy consumption and maintenance cost.

[0004] A battery clamp for automation production, comprising a clamp base, a lower clamping plate, an upper clamping plate and an opening clamp block, the lower clamping plate is installed on the clamp base, one end of the opening clamp block is connected with the upper clamping plate, and the other end penetrates through the lower clamping plate and the clamp base, the upper clamping plate and the lower clamping plate are connected with an elastic reset mechanism, and the elastic reset mechanism is installed on the clamp base.

[0005] In the above scheme, the opening clamp block is used to drive the upper clamping plate away from the lower clamping plate, so as to facilitate the feeding and clamping of the battery cell. One end of the opening clamp block penetrating through the lower clamping plate and the clamp base can be connected with a driving element such as air cylinder. The opening clamp block can drive the upper clamping plate to move upward by the driving element. Then the battery cell is placed on the lower clamping plate. The elastic reset mechanism automatically rebounds after the driving force is removed, so that the upper clamping plate stably and accurately presses the battery cell to form a stable clamping force, while reducing additional energy consumption. The clamp base is used for connecting the battery clamp and the automatic production equipment, so as to realize the automatic transportation and production of the battery cell. The overall structure is simple, which can greatly reduce the production cost and the occupied space.

[0006] Further, the elastic reset mechanism comprises a movable seat, a sliding assembly, a supporting assembly and an elastic assembly, the sliding assembly is installed on one side of the supporting assembly and connected with the movable seat, one end of the movable seat is connected with the upper clamping plate and the opening clamp block, and the other end of the movable seat is connected with the elastic assembly.

[0007] In the above scheme, the sliding assembly is supported by the support assembly, so that the movable seat can stably move along the sliding assembly, so that the movable seat can ensure that the upper clamping plate and the opening clamping block can stably and smoothly open and close the clamping of the battery, avoid the upper clamping plate from deviating or shaking during opening and closing, improve the alignment accuracy of the battery clamping, reduce the assembly error, and the elastic assembly is used to realize the automatic reset of the movable seat, so that the upper clamping plate and the opening clamping block can automatically clamp the battery, without the need for continuous external power input, thereby reducing energy consumption. At the same time, the elastic assembly has a certain buffering effect when clamping the battery with the upper clamping plate, which avoids deformation or surface damage of the battery caused by rigid impact.

[0008] Further, the support assembly comprises a mounting seat and a cover plate, the mounting seat is mounted on the clamp base, and the cover plate is mounted on the end of the mounting seat away from the clamp base. The cover plate is arranged on the elastic assembly.

The stepped groove limits the end surface of the elastic member to avoid radial movement of the end of the spring, solves the stress concentration problem caused by traditional plane contact, and prolongs the service life of the elastic member.

[0014] Further, the sliding assembly comprises a linear guide rail and a sliding block, the sliding block is movably mounted on the linear guide rail, the mounting seat is provided with a mounting groove, and the linear guide rail is vertically embedded in the mounting groove.

[0015] In the above scheme, the precise ball fitting structure of the linear guide rail and the slider provides a movement accuracy of mu m level, fully meets the requirements of the precise assembly process such as the battery pole piece stacking, the linear guide rail is vertically installed in the mounting groove, so that the structure is more compact, the volume of the whole clamp can be reduced, and the two ends of the slider are provided with limiting, without additional limiting block structure, thereby reducing the production cost.

[0016] Further, the movable seat is provided with a connecting groove, and the slider is embedded in the connecting groove.

[0017] In the above scheme, the nested design of the connecting groove and the slider makes the clamp more compact than the traditional externally mounted clamp, thereby reducing the occupied space of the clamp.

[0018] Further, the opening clamp block is T-shaped, a first connecting part in the horizontal direction of the opening clamp block is connected with the upper clamp plate, and a second connecting part in the vertical direction of the opening clamp block penetrates through the through hole of the clamp base.

[0020] Further, the clamp base is provided with a limiting block, and the two ends of the first connecting part can abut against the limiting block.

[0021] In the above scheme, the limiting block can effectively prevent the stroke of the opening clamp block from being out of limit, avoid the damage of the overstroke of the upper clamp plate to the battery cell, and play a limiting protection role.

[0022] Further, one end of the clamp base is provided with an RFID card.

[0023] In the above scheme, one RFID card is installed on each clamp, which can record the information such as clamp ID, specification, use frequency, avoid manual recording errors, and track the maintenance period and wear state of the clamp, so as to replace or maintain in time, through the RFID technology, the intelligent management of the battery clamp can significantly improve the production consistency, traceability and efficiency.

The lower clamp plate 2 is installed on the clamp base 1. One end of the opening clamp block 4 is connected with the upper clamp plate 3, and the other end penetrates through the lower clamp plate 2 and the clamp base 1. The upper clamp plate 3 and the lower clamp plate 2 are connected with an elastic reset mechanism 5, which is installed on the clamp base 1.

The opening clamp block 4 can drive the upper clamp plate 3 to move upward by being pushed by the driving element. Then, the battery cell is placed on the lower clamp plate 2. After the driving force is removed, the elastic reset mechanism 5 automatically rebounds, which makes the upper clamp plate 3 stably and accurately press the battery cell, thereby forming a stable clamping force and reducing the consumption of additional energy.
