Description

Technical Field

[0001] This utility model relates to the field of automated assembly of lithium-ion batteries, specifically to a lithium battery assembly gripping component. Background Technology

[0002] With the explosive growth of the electric vehicle, energy storage system, and portable electronic device markets, the production and scale of lithium-ion batteries are expanding at an unprecedented rate. In the battery production process, the winding process is the most critical step in forming a battery cell: the positive and negative electrode sheets and the separator are layered and precisely wound to obtain a bare cell with a flat or cylindrical shape. However, bare cells immediately after emerging from the winding machine present the following typical challenges:

[0003] 1. The structure is flexible but has low stiffness.

[0004] Bare battery cells consist of multiple layers of electrodes and separators, making them thick and heavy but lacking a rigid framework. If the stress distribution is uneven, the clamping area is prone to localized deformation, and may even develop wrinkles or cracks.

[0005] 2. The electrode plates and diaphragm are easily punctured or crushed.

[0006] Traditional robotic arms typically use metal or hard plastic grippers, resulting in a high concentration of gripping force and high hardness of the gripper ends. This makes it difficult to achieve uniform force distribution within a short period of time, easily causing micro-cracks on the edges of electrodes or separators. Accumulation of these micro-cracks can lead to decreased electrochemical performance, battery capacity degradation, or internal short circuits, and in severe cases, even safety accidents.

[0007] 3. Detect the risk of instability and fall.

[0008] Relying solely on either mechanical clamping or vacuum adsorption makes it difficult to balance stability and flexible protection. If the grippers clamp too tightly, they can damage the battery cells; if the vacuum chuck does not adsorb sufficiently, it may slip or fall off during handling or transport, causing line shutdowns for maintenance, component scrapping, and potential safety hazards.

[0009] 4. The contradiction between high cycle time and low yield

[0010] To reduce damage, many production lines choose to reduce gripping speed, increase intermediate inspections, or require manual intervention, thus slowing down the production line cycle and making it difficult to meet the production needs of large-volume, high-speed operations. In addition, the lack of effective protection will lead to an increase in the scrap rate of appearance defects, further driving up costs.

[0011] 5. Difficulty in adapting multiple battery cell models

[0012] The market exhibits significant differences in parameters such as cell size, weight, electrode materials (e.g., silicon-based, ternary, lithium iron phosphate), and winding tightness. Existing gripping devices are often optimized for a single model, lacking rapid switching and parameter adaptation capabilities, which limits the flexibility and versatility of assembly lines.

[0013] In view of the above-mentioned technical pain points, developing a gripping component that can provide uniform and controllable mechanical support for flexible cells, while also taking into account the high-speed automated production cycle and adapting to various cell specifications has become an important research direction for improving production line efficiency, reducing yield loss, and ensuring battery safety and consistency. Utility Model Content

[0014] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a lithium battery assembly gripping component that combines suction cup adsorption with multiple pairs of clamps. The clamps are protected with soft silicone to safeguard the bare battery cells. The structure is rationally laid out and can grip the bare battery cells stably, reliably, and safely.

[0015] To achieve the above objectives, this utility model is implemented through the following technical solution: a lithium battery assembly gripping component, including a cylinder fixing plate, a mounting plate, a clamp fixing plate, a clamp, a suction cup, a cylinder, and soft silicone. The cylinder fixing plate is provided on the lower sides of both sides of the mounting plate through a connecting plate. A cylinder is provided inside the cylinder fixing plate. The cylinder rod of the cylinder is connected to the clamp fixing plate. A clamp is provided in the lower middle part of the clamp fixing plate. Soft silicone is provided inside the clamp where it contacts the bare battery cell. A suction cup for adsorbing the bare battery cell is also provided on the mounting plate.

[0016] Preferably, the clamps are provided in multiple pairs to ensure clamping stability.

[0017] This utility model has the following beneficial effects:

[0018] 1. Combining suction cup adsorption and chuck clamping, it can grasp bare battery cells more stably and reliably, improving the success rate and stability of grasping.

[0019] 2. Soft silicone is used at the contact point between the chuck and the bare battery cell to prevent damage to the bare battery cell during clamping, thus protecting the integrity and performance of the bare battery cell.

[0020] 3. The clamps are set with multiple pairs, which ensures multi-point clamping of the bare battery cell during the gripping process, further enhancing the stability of the gripping and reducing the risk of the bare battery cell falling or shaking during gripping and movement.

[0021] 4. The cylinder fixing plate is set on both sides of the mounting plate below the connecting plate. The overall structure layout is reasonable, which facilitates the coordinated work of various components and realizes efficient gripping operation. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0023] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Reference Figure 1 The specific embodiment adopts the following technical solution: a lithium battery assembly gripping component, including a cylinder fixing plate 1, a mounting plate 2, a clamp fixing plate 3, a clamp 4, a suction cup 5, a cylinder 6, and soft silicone 7. The cylinder fixing plate 1 is provided on the lower sides of both sides of the mounting plate 2 through a connecting plate. The cylinder 6 is provided inside the cylinder fixing plate 1. The cylinder rod of the cylinder 6 is connected to the clamp fixing plate 3. The clamp 4 is provided in the lower middle part of the clamp fixing plate 3. Soft silicone 7 is provided at the contact point between the clamp 4 and the bare battery cell 8. The mounting plate 1 is also provided with a suction cup 5 for adsorbing the bare battery cell.

[0026] It is worth noting that multiple pairs of clamps 4 are provided to ensure the stability of clamping.

[0027] The working principle of this specific implementation is as follows: When it is necessary to grasp a bare battery cell, the suction cup on the mounting plate is activated to adsorb the bare battery cell. At the same time, the cylinder in the cylinder fixing plate is activated, and the cylinder rod pushes the clamp fixing plate, causing the clamp in the lower part of the clamp fixing plate to move towards the bare battery cell. Finally, the clamp clamps the bare battery cell, and the soft silicone at the contact point between the clamp and the bare battery cell plays a role in buffering and better fit, thereby achieving stable grasping of the bare battery cell.

[0028] This specific implementation method uses a combination of suction cup adsorption and multiple pairs of clamps. The clamps are protected with soft silicone to protect the bare battery cells. The structure is reasonably laid out and can stably, reliably and safely grip the bare battery cells.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
