Description

Technical Field

[0001] This utility model relates to a clamping device used in the lithium battery manufacturing process, specifically a clamping device for inserting square-shell batteries into slots. Background Technology

[0002] With the increasing global demand for new energy applications such as electric vehicles and energy storage devices, lithium batteries, as core energy storage units, are being used more and more widely in various products. The production process of lithium batteries is complex, especially in the battery assembly stage, where the placement of lithium batteries into the battery slots is crucial to the battery's safety, reliability, and production efficiency.

[0003] Currently, traditional lithium battery insertion fixtures mostly rely on manual or simple mechanical methods for battery insertion and fixation. This method has several problems: First, due to the shape of square batteries, traditional fixtures may not be able to guarantee the precise positioning of the battery in the slot during clamping, resulting in uneven contact between the battery and the slot, and may even cause safety hazards such as short circuits; second, manual operation or basic mechanical devices are difficult to meet the needs of high-efficiency production and cannot effectively improve the efficiency of the production line.

[0004] To address the aforementioned issues, there is an urgent need for a clamping device that can accurately and efficiently insert lithium batteries into the slot. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a square-shell battery insertion clamp that can accurately position and secure the battery, ensuring that the battery is not damaged by any external force when entering the slot. Simultaneously, the clamp should be designed to be simple, easy to operate, and adaptable to the needs of automated production lines, reducing manual intervention and improving production efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a square battery slot clamp, comprising a cylinder fixing plate, a cylinder connecting rod, a guide rod, a pressure plate, a movable partition, a middle partition, and a cylinder. Multiple cylinder fixing plates are arranged in parallel pairs to form a frame structure. A cylinder is fixed to the outside of the cylinder fixing plate. A guide rod is also provided between the cylinder fixing plates. A pressure plate is provided on the guide rod. A movable partition is provided between the pressure plates. A middle partition is provided in the middle of the movable partition. The cylinder is connected to the pressure plate through the cylinder connecting rod. The pressure plate clamps the battery cell.

[0007] Preferably, the pressure plate, movable partition, and intermediate partition form a groove-like structure in the middle.

[0008] The beneficial effects of this invention are as follows: Employing high-precision positioning and clamping technology, it effectively overcomes the shortcomings of traditional devices. The clamping structure of this invention is simple, ensuring stable battery placement in the slot during efficient production. Through precise guiding design and a mechanized clamping mechanism, this device reduces losses during battery assembly and improves the overall efficiency of the production line. Attached Figure Description

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0011] 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.

[0012] Reference Figure 1 The specific embodiment adopts the following technical solution: a square battery slot clamp, including a cylinder fixing plate 1, a cylinder connecting rod 2, a guide rod 3, a pressure plate 4, a movable partition 5, a middle partition 6 and a cylinder 7. Multiple cylinder fixing plates 1 are arranged in parallel in pairs to form a frame structure. A cylinder 7 is fixed on the outside of the cylinder fixing plate 1. A guide rod 3 is also arranged between the cylinder fixing plates 1. A pressure plate 4 is arranged on the guide rod 3. A movable partition 5 is arranged between the pressure plates 4. A middle partition 6 is arranged in the middle of the movable partition 5. The cylinder 7 is connected to the pressure plate 4 through the cylinder connecting rod 2. The pressure plate 4 is clamped to the battery cell.

[0013] It is worth noting that the pressure plate 4, the movable partition 5, and the intermediate partition 6 form a groove-like structure in the middle.

[0014] The working principle of this specific embodiment is as follows: First, the battery cell to be placed in the slot is fed into the designated position of the fixture by an external mechanism (such as a robotic arm or conveyor belt). The battery cell is placed between the pressure plate 4 and the movable partition 5. Once the battery cell is in place, the cylinder 7 starts working. The cylinder 7 pushes the pressure plate 4 through the cylinder connecting rod 2, causing it to move bidirectionally along the guide rod 3. The function of the guide rod 3 is to ensure the accurate movement direction of the pressure plate 4, avoiding deviation or jamming. Under the push of the cylinder 7, the pressure plate 4 moves towards the battery cell and cooperates with the movable partition 5 to clamp the battery cell. The design of the movable partition 5 and the intermediate partition 6 ensures that the battery cell is subjected to uniform force during clamping, avoiding damage to the battery cell due to excessive local pressure. The pressure plate 4 and the movable partition 5 firmly fix the battery cell in the fixture, ensuring that the battery cell will not be interfered with or damaged by any external force when entering the slot. At this time, the battery cell has been accurately positioned and fixed, and the next step of slotting operation can be safely carried out. The entire clamping and fixing process is automatically completed by cylinder 7, requiring no manual intervention and meeting the needs of automated production lines. This not only improves production efficiency but also reduces errors and damage that may be caused by human operation. After the battery cell completes the insertion into the slot, cylinder 7 moves in the reverse direction, and pressure plate 4 and movable partition 5 release the battery cell. The external mechanism can then remove the battery cell from the fixture for the next process.

[0015] In this specific embodiment, the battery cell to be placed in the slot is fed into the clamp by an external mechanism. The pressure plate then moves bidirectionally under the push of an external cylinder to achieve clamping. This clamp can accurately position and fix the battery, ensuring that the battery is not damaged by external forces when entering the slot. It also simplifies the operation process, improves production efficiency, and meets the needs of automated production lines. This clamp is designed for the positioning and fixing of lithium batteries during the assembly process. It plays a crucial role in the battery production and assembly process and is widely used in the lithium battery manufacturing industry, especially for the production process of square lithium batteries.

[0016] 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.
