Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and in particular relates to a battery hot pressing upper and lower material clamping claw mechanism. Background Art

[0002] In the field of battery manufacturing technology, the hot pressing process is very critical because it directly affects the performance and quality of the battery. However, during the process of loading and unloading the battery cells, the clamps may cause problems such as pinching and crushing the battery cells, which will cause the battery cells to have adverse conditions, thereby slowing down the production line production speed. Therefore, how to effectively avoid damage to the battery cells during loading and unloading, and improve the quality and production efficiency of the battery cells, is an urgent problem to be solved in battery manufacturing technology. During the battery assembly process, the battery cells need to be hot pressed after preheating to fix their shape. However, if the size of the clamps is not appropriate when loading the battery cells, it may cause the battery cells to fall and affect the production speed. Therefore, how to optimize the clamping method of the battery cell clamps is also one of the problems that need to be solved in the loading and unloading of the battery cells on the entire line.

[0003] The existing solutions mainly reduce the damage to the battery cells by improving equipment and processes. For example, the material of the mechanical gripper can be improved to minimize the damage caused during the loading and unloading process. At the same time, the defects can be reduced by optimizing the process, such as controlling the clamping force of the gripper. However, there are still some problems with the existing technology in practical applications. First, the existing solutions can often only reduce some of the pinching injuries and cannot completely eliminate them. Secondly, the existing solutions often increase the probability of battery cells falling while reducing damage. Under this trade-off, the stability and efficiency of the production line may be affected. Utility Model Content

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] like Figure 1 As shown: A battery hot pressing loading and unloading clamping jaw mechanism, comprising a mounting base plate 1, a clamping and lifting mechanism 2 and a battery cell suction mechanism 3, wherein the clamping and lifting mechanism is mounted on the mounting base plate for clamping and lifting the battery cell 4, and the battery cell suction mechanism is mounted on the mounting base plate for sucking the battery cell and placing it on the clamping and lifting mechanism. The clamping and lifting mechanism can be any mechanism as long as it can achieve clamping and lifting actions, for example, it can be a robot. The battery cell suction mechanism is mainly used to suck up the battery cell, and can also be a robot structure with a suction cup. The device adopts a traditional battery cell clamp in conjunction with a battery cell suction cup module. The suction cup first sucks up the battery cell and then the clamp holds the battery cell for operation, ensuring that the clamp will not damage the battery cell when the battery cell is loaded and unloaded.

[0024] Specifically, Figure 1 As shown, in this embodiment, the clamping and lifting mechanism 2 includes a clamping cylinder 21, a left clamping arm 22, a right clamping arm 23, a left clamping jaw 24 and a right clamping jaw 25; the clamping cylinder adopts an SMC type thin air jaw, which is a purchased part, and both ends of the air jaw are equipped with piston rods, which can act simultaneously, and the clamping cylinder is fixed on the mounting base plate, and the piston rods on both sides of the clamping cylinder are respectively fixed to the left clamping jaw arm and the right clamping jaw arm. In order to make the left clamping jaw arm and the right clamping jaw arm move more freely and smoothly, a slide rail 11 is fixed on the mounting base plate. In this device, there are two slide rails, which are respectively located on both sides of the clamping cylinder. The number of slide rails can be selected according to the size of the left and right clamping jaw arms. Accordingly, the bottom of the left and right clamping jaw arms are respectively fixed with sliders 12 that slide with the slide rails. The left and right clamping jaw arms slide on the slide rails through the sliders, and the opening and closing of the left and right clamping jaw arms realize the clamping of the battery cell. In order to be able to hold the battery cell from the bottom while clamping the battery cell, the front ends of the left clamp arm and the right clamp arm are respectively fixed with the left clamp arm and the right clamp arm, and the cross-section of the left clamp arm and the right clamp arm is L-shaped. The left clamp arm and the right clamp arm are driven to move by the clamp cylinder, thereby driving the left clamp arm and the right clamp arm to clamp the battery cell and hold up the battery cell, so that the transfer of the battery cell is more stable.

[0025] Specifically, Figure 1 and Figure 3 As shown, in this embodiment, the battery cell suction mechanism 3 includes a suction cup lifting cylinder 31, a connecting block 32 and a suction cup 33. The suction cup lifting cylinder is installed on the mounting base plate through the connecting block. The movable end of the suction cup lifting cylinder is connected to the suction cup. The suction cup is driven to move up and down by the suction cup lifting cylinder to suck the battery cell. The suction cup is located at the center between the left clamp and the right clamp. After the suction cup sucks the battery cell, the left clamp and the right clamp are closed to clamp and lift the battery cell. The suction cup lifting cylinder drives the suction cup to suck the battery cell, which can avoid damaging the surface of the battery cell and preventing the battery cell from falling.

[0026] like Figure 3 As shown, in this embodiment, the movable end of the suction cup lifting cylinder is the cylinder body 311, and the piston rod 312 of the suction cup lifting cylinder is fixed on the connecting block. The cylinder body moves, and a connecting plate 34 is fixed on the cylinder body. One end of the connecting plate fixes the suction cup. When the suction cup lifting cylinder is working, the piston rod remains stationary because it is fixed on the connecting block, and the cylinder body moves, and the cylinder body drives the suction cup to move up and down through the connecting plate to absorb the battery cell.

[0027] Furthermore, in order to protect the surface of the battery core, a buffer sponge 35 is installed at the bottom of the suction cup. The buffer sponge can prevent the suction cup from scratching the surface of the battery core when sucking the battery core.

[0028] Working principle: The device as a whole moves to the battery cell loading position, the clamping claw cylinder moves to separate the left and right clamping claws, then the suction cup lifting cylinder moves down to suck the battery cell, then the suction cup lifting cylinder drives the battery cell to move above the left and right clamping claws, then the clamping claw cylinder moves to close the left and right clamping claws to hold the battery cell, then the suction cup puts the battery cell down, the device as a whole drives the battery cell to the unloading position, then the suction cup lifting cylinder moves down to drive the suction cup to suck the battery cell, then the left and right clamping claws separate, finally the suction cup lifting cylinder drives the suction cup and the battery cell to move down to the unloading position, the suction cup loosens the battery cell, and the battery cell transmission work is completed.

[0029] For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
