Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a soft-pack arc-shaped battery cell forming equipment with automatic feeding and unloading functions. Background Technology

[0002] The soft-pack arc-shaped battery cell is an irregularly shaped lithium-ion battery packaged with aluminum-plastic film. The overall shape is an arc with continuous curvature, retaining the characteristics of soft-pack battery cells being thin, light, and flexible. The internal components consist of positive and negative electrode sheets, separators, etc. The arc shape is shaped through a process, which has strong spatial adaptability and can fit curved devices or irregular structures, reducing installation space waste. It is used in scenarios that require customized battery shapes, such as smartwatches, VR devices, and curved automotive structural parts.

[0003] The soft-pack curved battery cell forming equipment with automatic feeding and unloading functions is an automated equipment for mass production of soft-pack curved battery cells. It integrates automatic feeding, arc forming and automatic unloading functions and consists of an automatic feeding module, an arc forming unit and an automatic unloading module. The automatic feeding module accurately transports the soft-pack battery cells to be processed to the forming station. The arc mold at the forming station closes, and the battery cells are shaped into an arc shape by temperature control and pressure. After forming, the battery cells are inspected. Qualified battery cells are sent to the next stage by the automatic unloading module, and unqualified products are diverted.

[0004] In some existing devices, the soft-pack arc-shaped battery cell forming equipment with automatic feeding and unloading functions lacks an effective buffering mechanism during feeding and unloading. This causes the soft-pack battery cell to collide rigidly with the device, resulting in deformation of the soft-pack battery cell. At the same time, the correction method is manual adjustment or mechanical rigid adjustment, which increases the probability of deformation and wrinkling of the soft-pack battery cell and reduces the quality of the product. Therefore, a soft-pack arc-shaped battery cell forming equipment with automatic feeding and unloading function is proposed to solve the above problems. Utility Model Content

[0013] As a further description of the above technical solution:

An movable groove is opened inside the stamping table.

[0015] As a further description of the above technical solution:

[0016] The buffer plate is externally slidably connected to the inside of the calibration box, and the gear shaft is externally meshed with the left side of one of the sliding plates;

[0017] As a further description of the above technical solution:

[0018] The outer side of the sliding plate is slidably connected to the inside of the buffer cavity, and the outer side of the buffer clamping block is slidably connected to the inside of the buffer groove;

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when the soft-pack battery cell impacts the buffer plate, spring one absorbs the impact, reducing damage to the soft-pack battery cell. When the motor starts, it drives the gear shaft, which in turn drives the sliding plate meshing with the gear shaft to move. When the buffer clamping block contacts the soft-pack battery cell, spring two is compressed under pressure, absorbing the impact. The buffer clamping block pushes the soft-pack battery cell to the center position to complete the correction, thus achieving buffer protection for the soft-pack battery cell, reducing damage to the soft-pack battery cell during the feeding process, adjusting the position of the soft-pack battery cell, ensuring that the soft-pack battery cell does not deviate during subsequent stamping, and improving product quality.

[0025] 2. In this utility model, when the second motor starts, it drives the rotating shaft to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel converts the rotational motion into reciprocating linear motion, which drives the movable plate to move up and down. The upward movement of the movable plate presses the third spring. The third spring is under pressure and pushes the demolding template upward. Under the action of the third spring, the demolding template pushes out the soft-pack battery cell to complete the demolding. This realizes the buffering effect of the third spring, making the demolding process more gentle, effectively reducing the extrusion deformation of the soft-pack arc-shaped battery cell, and improving the quality of the product.

[0038] Reference Figure 3 and Figure 4 The buffer plate 2604 is externally slidably connected to the inside of the calibration box 2601. The calibration box 2601 provides movement space for the buffer plate 2604 and provides a buffer base. The gear shaft 2606 is externally meshed with the left side of one of the sliding plates 2607.

The external rotating connection of the eccentric wheel 324 is inside the stamping table 321. The stamping table 321 provides space for the eccentric wheel 324 to move.

[0039] Working principle: During feeding, the soft-pack battery cell is conveyed from the feeding conveyor belt 21, slides onto the calibration platform 23 above the sliding inclined plane 22, and the air blown by the fan 24 blows upward through the air blowing hole 25, which can reduce the resistance of the soft-pack battery cell sliding and blow away impurities. When the soft-pack battery cell hits the buffer plate 2604, the spring 2603 absorbs the impact and reduces the damage to the soft-pack battery cell. The motor 2605 starts and drives the gear shaft 2606, which in turn drives the sliding plate 2607 connected to the gear shaft 2606 to move. When the buffer clamping block 2610 contacts the soft-pack battery cell, the spring 2609 is compressed by pressure to absorb the impact. The buffer clamping block 2610 pushes the soft-pack battery cell to the center position to complete the calibration. Then, the clamp 5 picks up the soft-pack battery cell and puts it into the stamping table 321 to complete the feeding. The stamping machine 31 stamps the soft-pack battery cell into shape.

[0040] During demolding and unloading, motor 2 322 starts, driving the rotating shaft 323 to rotate, which in turn drives the eccentric wheel 324 to rotate. The eccentric wheel 324 converts the rotational motion into reciprocating linear motion, which drives the movable plate 325 to move up and down. The upward movement of the movable plate 325 presses the spring 326. The spring 326 is under pressure and pushes the demolding template 327. Under the action of the spring 326, the demolding template 327 pushes out the soft-pack battery cell to complete the demolding. The clamp 5 takes the soft-pack battery cell out from the stamping table 321 and puts it into the unloading conveyor belt 6.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
