Description

Technical Field

[0001] This application relates to the field of battery cell processing technology, and in particular to an L-shaped battery cell separator hot-stamping mechanism. Background Technology

[0002] In the production process of L-shaped battery cells, the hot-pressing of the separator before the cell is assembled into the casing is a critical step. During cell processing, the separator often overflows from the short side. If left unchecked, this overflow can cause the cell size to exceed the preset range, affecting the accuracy and stability of subsequent assembly. Therefore, the hot-pressing process tightens the overflowing separator on the short side, effectively controlling the overall size of the cell and laying the foundation for smooth operation of subsequent processes.

[0003] Currently, the industry mostly uses manual operation for heat sealing the separator edges of L-shaped battery cells. Specifically, the operator needs to hold the battery cell and carefully bring the part of the short side of the cell that extends out of the separator close to a heating block with a pre-set temperature. The high temperature of the heating block causes the separator to shrink, thereby achieving a tightening effect.

[0004] Regarding the aforementioned technologies, the inventors believe that the speed of manual operation is greatly affected by factors such as the operator's skill level and physical condition, resulting in low overall production efficiency. Utility Model Content

[0005] The purpose of this application is to provide an L-shaped battery cell separator hot-pressing mechanism to improve the problem of low overall production efficiency caused by manual operation.

[0006] This application provides a hot-stamping mechanism for the separator of an L-shaped battery cell, which adopts the following technical solution:

[0007] An L-shaped battery cell separator edge-heating mechanism includes a base frame. A slide rail is provided on the top surface of the base frame along its length. A slider is slidably mounted on the slide rail. A movable plate is mounted on the slider. A driving component for moving the movable plate is provided at one end of the base frame. A telescopic driving component is provided on the top surface of the movable plate along the width direction of the base frame. A base plate is provided above the telescopic driving component. A fixing block is provided on the bottom surface of the base plate and is fixedly connected to the output end of the telescopic driving component. A plurality of edge-heating components are provided on the top surface of the base plate. Each edge-heating component includes a gripper cylinder. The gripper cylinder is provided with a set of clamping plates that can approach each other. A heating block for clamping the separator is provided on the side of the set of clamping plates that are close to each other.

[0008] By adopting the above technical solution, the telescopic drive pushes the base plate and the hot-edge assembly closer to the battery cell, the gripper cylinder drives the clamping plate and heating block to clamp the diaphragm for hot-edge treatment, and the drive unit drives the moving plate to move along the slide rail to hot-edge the diaphragm along the length of the battery cell, reducing the dependence on the operator's skill level and physical condition and improving production efficiency.

[0009] Optionally, an elastic element is provided between a set of clamping plates, and the two ends of the elastic element are respectively fixed to the side of the set of clamping plates that is close to it.

[0010] By adopting the above technical solution, when the clamping cylinder drives the clamping plate close to the diaphragm, the elastic element is stretched, and its rebound force can enhance the clamping force of the clamping plate on the diaphragm, making the contact between the heating block and the diaphragm closer and more stable, thus improving the consistency of the hot edge quality.

[0011] Optionally, the clamping plate is provided with a protective baffle around the heating block.

[0012] By adopting the above technical solution, the protective baffle can prevent the heating block from directly contacting the battery cell body, preventing the battery cell from being damaged due to high temperature. At the same time, it can prevent operators from accidentally touching the high-temperature heating block during equipment operation or maintenance, thereby improving the safety of equipment use and reducing the risk of battery cell damage or personnel burns due to negligence during manual operation.

[0013] Optionally, the heating block is provided with a stepped groove.

[0014] By adopting the above technical solution, the stepped slot can be adapted to the short-side overflow diaphragm of L-shaped cells of different thicknesses, which can more accurately lock the edge of the diaphragm and ensure that the heating block only heats the part of the diaphragm that needs to be tightened, thus improving the accuracy of the hot edge.

[0015] Optionally, one end of the base frame is provided with a limiting rod along its length that can abut against the movable plate.

[0016] By adopting the above technical solution, the limiting rod restricts the movement stroke of the moving plate, ensuring that the position reached by the moving plate with the battery cell is consistent each time, and fixing the relative position of the battery cell separator and the hot-stamping assembly, thus ensuring the consistency of hot-stamping of each batch of battery cells.

[0017] Optionally, the limiting rod is provided with a threaded section and is threadedly connected to the base frame to adjust the length of the limiting rod.

[0018] By adopting the above technical solution, the extension length of the rotating limit rod can be easily adjusted, thereby adjusting the maximum moving distance of the moving plate, enabling the mechanism to adapt to the processing requirements of L-shaped battery cells of different sizes, and enhancing the versatility and flexibility of the mechanism.

[0019] Optionally, a fixed plate is provided on the top surface of the movable plate at one end of the telescopic drive component, and an elastic element two is provided on the side of the fixed plate near the fixed block. The end of the elastic element two away from the fixed plate is fixed to the fixed block.

[0020] By adopting the above technical solution, when the telescopic drive pushes the base plate close to the battery cell, the fixed block compresses the elastic element two. The buffering effect of the elastic element two can prevent the base plate from rigidly colliding with the battery cell and protect the battery cell. When the telescopic drive retracts, the restoring force of the elastic element two can assist the base plate to return to its original position smoothly, which improves the stability of the mechanism and the protection of the battery cell.

[0021] Optionally, the gripper cylinder is equipped with a speed control valve.

[0022] By adopting the above technical solution, the opening and closing speed of the clamp can be adjusted according to factors such as the diaphragm material and thickness. This helps to prevent the diaphragm from being damaged due to excessive speed or the production efficiency from being affected by excessively slow speed. It further improves the adaptability of the mechanism and the precision of operation, and ensures the stability and efficiency of the hot edge process.

[0023] In summary, this application includes at least one of the following beneficial technical effects of the L-shaped battery cell separator edge-heating mechanism:

[0024] 1. The telescopic drive pushes the base plate and the hot edge assembly closer to the battery cell. The gripper cylinder drives the clamping plate and heating block to clamp the diaphragm for hot edge. The drive also drives the moving plate to move along the slide rail and hot edge the diaphragm along the length of the battery cell. This reduces the dependence on the operator's skill level and physical condition and improves production efficiency.

[0025] 2. The protective baffle can prevent the heating block from directly contacting the battery cell body, preventing the battery cell from being damaged due to high temperature. At the same time, it can prevent operators from accidentally touching the high-temperature heating block during equipment operation or maintenance, improving the safety of equipment use and reducing the risk of battery cell damage or personnel burns due to negligence during manual operation.

[0026] 3. The stepped slot is compatible with L-shaped battery cells with short-side overflow diaphragms of different thicknesses, which can more accurately lock the edge of the diaphragm and ensure that the heating block only heats the part of the diaphragm that needs to be tightened, thus improving the accuracy of edge heating.
