Description

Technical Field

[0001] This utility model relates to the field of battery clamping technology, specifically a battery sealing nail welding clamp. Background Technology

[0002] Battery sealing pins are specialized sealing components for lithium battery electrolyte filling holes. They are mainly used to seal the filling holes after the battery has been filled with electrolyte to isolate external air and moisture, and to ensure stable internal pressure. They are one of the key components that determine the battery's sealing performance and safety performance. The design and installation of sealing pins directly affect the battery's lifespan and safety.

[0003] Battery sealing nail welding fixtures are specialized tooling used in the sealing nail welding process of batteries (especially cylindrical and square lithium batteries). Their core function is to accurately fix the battery, position the sealing nail, and ensure the stability and safety of the welding process. Typically, the battery is fixed by mechanical or pneumatic structures during welding to prevent incomplete or missing welds caused by vibration.

[0004] When using existing battery sealing nail welding fixtures, it is mostly necessary to manually place the battery into the fixture, and then the welding equipment picks up the sealing nail and welds it to the outer wall of the battery. During this process, if there is a positional deviation in the placement of the battery, it is easy to cause the sealing nail welding position to shift, thereby reducing the welding accuracy. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a battery sealing nail welding fixture to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery sealing nail welding fixture, comprising a first push rod, a top plate at the output end of the first push rod, a fixing block and a second push rod mounted on the top of the top plate, a square battery body at one end of the fixing block, a push plate at the other end of the square battery body, a positioning plate at the top of the square battery body, a third push rod at one end of the positioning plate, a limit block at the output end of the third push rod, and a material discharge hole at one end of the limit block.

[0007] By adopting the above technical solution, the position of the square battery body is moved through the setting of the top plate and push plate. The top plate limits the upper and lower ends of the square battery body, and the push plate limits the left and right ends of the square battery body. This facilitates the welding equipment to weld the sealing nails through the material discharge hole, effectively improving the working efficiency of the device and the stability of the welding process, and reducing the displacement of the square battery body. Through the setting of sliders and slide rails, sliders are installed around the top plate, and a slide rail is set at the end of the support plate near the top plate. The sliders are located in the slide rail, which effectively improves the stability of the top plate during movement, and thus also improves the stability of the device during operation.

[0008] The present invention is further configured such that the feeding hole is positioned opposite to the positioning plate and the square battery body, and the top of the positioning plate has multiple sets of through holes.

[0009] Preferably, the through-hole design allows for observation of the mounting holes on the block battery body, effectively improving the device's working efficiency.

[0010] The present invention is further configured such that a second push rod is bolted to the top of the top plate, and a push plate is installed at the output end of the second push rod, the push plate being disposed opposite to the block battery body.

[0011] Preferably, one end of the push plate moves, which effectively improves the limiting of the left and right ends of the block battery body. Secondly, one end of the block battery body is provided with a fixing block and the fixing block is fixedly connected to the top plate.

[0012] The present invention is further configured such that a support plate is provided around the positioning plate, and a cube battery body is placed on the central axis of the support plate.

[0013] Preferably, the placement of the square battery body facilitates the picking and placing of the square battery body by the staff, effectively improving the working efficiency of the device.

[0014] The present invention is further configured such that a third push rod is provided at one end of the support plate, and the third push rod is located at one end of the positioning plate.

[0015] Preferably, the stability of the positioning plate is improved by setting a support plate to support the position of the positioning plate, thereby improving the stability of the device.

[0016] The present invention is further configured such that the top plate is sleeved inside the support plate, and the two ends of the push plate are also provided with support plates.

[0017] Preferably, the push plate is located in the middle of the support plate to facilitate the push plate to limit the position of the square battery body. Limiting the position of the square battery body from multiple angles improves the fit between the square battery body and the through hole.

[0018] The present invention is further configured such that the bottom of the positioning plate is in contact with the block battery body, and the mounting hole on the outer wall of the block battery body is located inside the through hole.

[0019] Preferably, the device facilitates the welding of sealing pins to the mounting holes of the block battery body through the discharge hole, effectively improving the stability of the device operation.

[0020] The present invention is further configured such that sliders are provided around the top plate, and a slide rail is provided at one end of the support plate near the top plate.

[0021] Preferably, the slider is fitted inside the slide rail, which effectively improves the stability of the top plate during movement.

[0022] The present invention is further configured such that the slider is sleeved inside the slide rail, and the slider and the slide rail are engaged, and the slider and the top plate are fixedly connected.

[0023] Preferably, this effectively improves the stability when the first push rod drives the top plate to move upward, and reduces the shaking generated during the movement of the block battery body.

[0024] In summary, the present invention has the following main advantages: 1. This utility model uses a top plate and a push plate to move the position of the block battery body. The top plate limits the upper and lower ends of the block battery body, and the push plate limits the left and right ends of the block battery body.
