Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a battery tab welding fixture. Background Art

[0002] The battery tab welding fixture is a tool specifically designed to precisely position and secure the battery tabs during the battery manufacturing process to facilitate welding operations. It plays a crucial role in ensuring the quality of battery tab welding. The battery tab is the part that connects the battery's internal electrode to the external circuit, and its welding quality directly affects the battery's performance and safety.

[0003] The existing technology uses manually operated clamping tools to clamp the battery and the tab separately, making it difficult to ensure that the tab is accurately positioned in the ideal welding position every time during use. Due to the visual error of the human eye and the instability of manual operation, the position of the tab will deviate greatly. When welding lithium batteries with extremely high precision requirements, this position deviation may cause the welding point to deviate from the designed position, increase the internal resistance of the battery, and affect the battery's charge and discharge performance and overall efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a battery tab welding fixture, comprising a mounting chamber and a clamping frame fixedly connected to the mounting chamber, wherein the inner wall of the mounting chamber is slidably connected to a second sliding plate, the second sliding plate is fixedly connected to a first sliding plate, and a clamping assembly is provided on the mounting chamber;

[0005] The clamping assembly includes a hand-held block, a flexible steel wire rope is threaded on the hand-held block, a first threaded rod is fixedly connected to the flexible steel wire rope, the first threaded rod is fixedly connected to a motor, the motor is fixedly connected to the bottom of the first sliding plate, a disc is slidably connected to the second sliding plate, a rotating shaft is rotatably connected to the disc, a clamping plate is rotatably connected to the rotating shaft, and the clamping plate is slidably connected to the second sliding plate.

[0006] As a preferred embodiment, two rotating shafts are provided, and the two rotating shafts are rotatably connected to the two ends of the clamping piece respectively, and the rotating shaft away from the disc among the two rotating shafts is rotatably connected to the clamping plate.

[0007] The above technical solution is adopted: by setting two rotating shafts to connect the clamping plate, the disc and the clamping block, and by stretching the disc during use, the clamping plate drives the clamping plate to slide inward on the second sliding plate, thereby realizing the clamping movement of the two clamping plates to clamp the tab.

[0008] As a preferred embodiment, sliding openings are provided on the installation compartment and the second sliding plate, and the disc is slidably connected to the sliding opening on the second sliding plate.

[0009] The above technical solution is adopted: by providing a sliding opening, the clamping plate is limited.

[0010] As a preferred embodiment, an opening is provided on the clamping frame, and the flexible steel wire rope is slidably connected in the opening on the clamping frame.

[0011] The above technical solution is adopted: by opening an opening on the clamping frame, when in use, the flexible steel wire rope will be tightened to tightly fix the battery and bind it to the first sliding plate.

[0012] As a preferred embodiment, a pulley is fixedly connected to the first sliding plate, and the flexible steel wire rope is transmission-connected to the pulley.

[0013] By adopting the above technical solution, the friction between the flexible steel wire rope and the first sliding plate can be reduced by providing a pulley.

[0014] As a preferred embodiment, a cross bar is fixedly connected to the first threaded rod, and the flexible steel wire rope is fixedly connected to the cross bar on the first threaded rod.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] In this utility model, a small electric telescopic rod is first installed between the mounting groove and disc of the first sliding plate and the second sliding plate. After the battery body is inserted into the clamping frame, the motor is started, which drives the first threaded rod to rotate. The first threaded rod is connected to a flexible steel wire rope, which is in a transmission connection with a pulley on the first sliding plate to reduce friction. As the first threaded rod rotates, the flexible steel wire rope is tightened, achieving initial clamping of the battery body. The operator can also twist the handle block for further adjustment, and the tension of the flexible steel wire rope can be fine-tuned by controlling the motor. After placing the tab, start the electric telescopic rod on the disc, which drives the disc downward through its extension and retraction. The disc is connected to the clamping piece and clamping plate through two rotating shafts. The movement of the disc causes the clamping piece to drive the clamping plate to slide on the second sliding plate, thereby clamping the tab. Then start the electric telescopic rod on the first sliding plate to push the second sliding plate to slide at the bottom of the first sliding plate, driving the tab to contact the battery body, completing the positioning, and then starting the welding process. This transmission method combining mechanical and electric operation avoids the visual and manual operation errors of manual operation, ensures that the tab is welded in the ideal position, improves the welding accuracy of batteries such as lithium batteries, and solves the problem of limited clamping accuracy of the existing technology in the background technology that relies solely on manual operation.

The inner wall of the mounting chamber 1 is slidably connected to a second sliding plate 41, and the second sliding plate 41 is fixedly connected to a first sliding plate 4. The mounting chamber 1 is provided with a clamping assembly 2;

[0032] The clamping assembly 2 includes a handheld block 21, a flexible steel wire rope 22 is threadedly connected to the handheld block 21, a first threaded rod 25 is fixedly connected to the flexible steel wire rope 22, a motor 24 is fixedly connected to the first threaded rod 25, and the motor 24 is fixedly connected to the bottom of the first sliding plate 4. A disc 28 is slidably connected to the second sliding plate 41, a rotating shaft 27 is rotatably connected to the disc 28, a clamping plate 29 is rotatably connected to the rotating shaft 27, and the clamping plate 29 is slidably connected to the second sliding plate 41;

[0033] In this utility model,

[0034] When in use, first install the small electric telescopic rod in the mounting groove on the first sliding plate 4 and between the disc 28 and the second sliding plate 41;

[0035] When in use, the battery body is directly inserted into the clamping frame 3, and the motor 24 is started, so that the motor 24 drives the first threaded rod 25 to rotate, thereby transmitting the flexible steel wire rope 22, so that the flexible steel wire rope 22 is tightened, thereby achieving preliminary clamping and fixing of the battery body;

[0036] The staff can twist the hand-held block 21 according to the actual situation to achieve complete clamping of the battery body. During this process, the tension of the flexible steel wire rope 22 can be finely adjusted by controlling the motor 24.

[0037] Place the tab between the two clamping plates 29, start the electric telescopic rod on the disc 28, so that the electric telescopic rod drives the disc 28 to move downward, so that the clamping piece 26 drives the clamping plate 29 to slide on the second sliding plate 41 to clamp the tab.

[0038] After that, the electric telescopic rod on the first sliding plate 4 is activated to make the second sliding plate 41 slide on the bottom of the first sliding plate 4 so that the tab contacts the battery body, and the welding process can begin;

[0039] First, a small electric telescopic rod is installed between the mounting slot and disc 28 of the first sliding plate 4 and the second sliding plate 41.
