Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a mechanical clamp for a component of the lower outer casing of a battery. Background Technology

[0002] As a core component of energy storage or power systems, the battery pack's outer lower casing is a crucial structural component ensuring the stability of battery module installation. During manufacturing, to meet subsequent assembly requirements, nuts need to be pre-embedded at the four corners inside the casing for secure connection. In existing technologies, the supply and removal of nuts in this pre-embedding process typically employ the following method: four nut placement positions corresponding to the four corners of the casing are pre-set on the feeding equipment; a material handling machine clamps the nuts from these four points and precisely places them in the pre-set positions of the lower casing injection mold, completing the pre-embedding operation; simultaneously, a separate unloading clamp is required to remove the injection-molded lower casing from the mold; However, in existing technologies, the mechanical clamps and unloading clamps used for picking up and placing nuts are mostly multiple independently set clamps, which need to work together to complete the entire process of picking up, pre-embedding, and unloading. This multi-clamp coordination mode not only leads to low overall efficiency of clamping and unloading operations, but also increases the complexity of the equipment structure and the cumbersome operation process, making it difficult to meet the requirements of automation and production continuity for large-scale production of lower casings. This, in turn, increases the time cost and management difficulty of the manufacturing process. Therefore, this utility model proposes a mechanical clamp for the components of the lower casing of the battery to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a mechanical clamp for components of the lower outer casing of a battery. This mechanical clamp facilitates continuous loading and unloading of finished products, reduces equipment costs, improves efficiency, and meets the needs of continuous production.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a mechanical clamp for a component of the lower outer casing of a battery, including a support arm, a support plate and a connecting arm, wherein the support plate is rotatably connected to the support arm, the connecting arm is provided in two sets, and the connecting arm is provided at one end of the support plate, and the connecting arm is provided with a clamping assembly, which is used to clamp the lower casing. Adjustment components are provided at the four corners of the support plate, and the output end of the adjustment component is connected to an adsorption rod.

Example

[0021] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a mechanical clamp for a component of the lower outer casing of a battery, including a support arm 1, a support plate 2 and a connecting arm 3. The support plate 2 is rotatably connected to the support arm 1. The connecting arm 3 is provided in two sets and is located at one end of the support plate 2. The connecting arm 3 is provided with a clamping assembly, which is used to clamp the lower casing 4. Adjustable components are provided at each of the four corners of the support plate 2, and the output end of the adjustable components is connected to an adsorption rod 5. The bottom of the adsorption rod 5 is provided with a magnetic suction hole, which is used to magnetically attract nuts. In use, this device is connected to a robotic arm, which moves the device to the nut feeding equipment. The height of the adsorption rod 5 is adjusted by the adjustable components. First, the two sets of lower adsorption rods 5 magnetically attract nuts at two points, and then the two sets of upper adsorption rods 5 magnetically attract nuts at two points. The entire process only requires lifting and lowering to complete the adsorption of nuts at four points. The material handling stroke is lower. Before subsequent nut feeding, the lower box 4, which has been formed in the injection molding area, is first removed by the clamping assembly, and then the nuts are fed. After feeding, the lower box 4 can be sent to the unloading area. In summary, this facilitates the continuous feeding and unloading of finished products, reduces equipment costs, improves efficiency, and meets the needs of continuous production.

[0022] Positioning cylinders 19 are provided at both ends of the support plate 2, and the output end of the positioning cylinders 19 is connected to a positioning rod 13.

[0024] The mechanical clamps for the components of the lower outer casing of the battery are connected to a robotic arm. The robotic arm moves the components to the nut loading device. The height of the adsorption rods 5 is adjusted by the adjusting components. First, the two lower sets of adsorption rods 5 magnetically adsorb the nuts at two points, then the two upper sets of adsorption rods 5 magnetically adsorb the nuts at two more points. The entire process only requires lifting and lowering to adsorb the nuts at four points, resulting in a lower material handling stroke. Before subsequent nut loading, the already molded lower casing 4 from the injection molding area is removed using the clamping assembly, and then the nuts are loaded.
