Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a sealing nail welding device for batteries. Background Technology

[0002] Most existing electronic devices use sealed batteries such as lithium-ion batteries or nickel-metal hydride batteries. During the production of sealed batteries, after injecting electrolyte, the electrolyte injection port needs to be sealed with a nail to prevent leakage. An existing lithium battery sealing nail welding device (publication number CN222176435U) uses a feeding mechanism and a pushing component to load batteries. However, after processing each finished product, the clamping mechanism needs to be released before loading the next part. This design is overly cumbersome, and when changing parts, the workpiece is prone to tipping over, affecting processing speed. Utility Model Content

[0003] The purpose of this invention is to provide a battery sealing nail welding device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A battery sealing nail welding device includes a mounting frame with an I-shaped slide rail fixed to its upper surface. It also includes a movable plate slidably connected to the I-shaped slide rail. A feeding mechanism is provided on the upper surface of the movable plate. The feeding mechanism includes a slide rail fixed to the movable plate, a feeding cylinder mounted on one end of the slide rail, a top plate fixed to the extended end of the feeding cylinder, fixed plates fixed at both ends of the top plate, rotating plates at both ends of the fixed plates, rollers on the outer sides of the fixed plates and rotating plates, a bottom plate mounted on one end of the rotating plate, a material plate on the bottom plate, and a clamping machine on one side of the feeding mechanism. The fixture mechanism includes a bracket fixed to a movable plate, a sliding rod and left and right helical screws mounted on the bracket, clamping blocks mounted on the left and right helical screws, and a power component connected to the protruding shaft of one end of the left and right helical screws. A baffle is fixed to one side of the bracket, a welding machine bracket is fixed to the mounting frame, and a welding machine is mounted on the welding machine bracket. A sliding mechanism is provided on the lower surface of the mounting frame. The sliding mechanism includes a housing fixed to the lower surface of the mounting frame, a helical screw inside the housing, a threaded block on the outer surface of the helical screw, and a stepper motor connected to the protruding shaft of one end of the helical screw.

[0006] Further configuration: The feeding cylinder is fixed inside the slide rail, the rotating plate is rotatably connected to the fixed plate, the roller is rotatably connected to the rotating plate and the fixed plate, the roller is slidably connected to the slide rail, and the base plate is rotatably connected to the rotating plate.

[0007] Further configuration: The clamp block is slidably connected to the slide rod, the left and right helical screws are threadedly connected to the clamp block, and the left and right helical screws are rotatably connected to the bracket.

[0008] Further settings: The welding head of the welding machine is aligned with the center point of the clamp block, and the groove spacing on the material plate is equal to the clamping spacing on the clamp block.

[0009] Further configuration: The screw is rotatably connected to the housing, the threaded block is threadedly connected to the screw, and the threaded block is fixedly connected to the moving plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By setting up a feeding mechanism and a clamping mechanism, the feeding cylinder of the feeding mechanism pushes the top plate, which in turn drives the rollers on the outer side of the fixed plate and the rotating plate to move along the slide rail. When the rollers contact the baffle, the rotating plate rotates due to the reaction force of the baffle, which drives the bottom plate to move upward. Then, the power component of the clamping mechanism drives the left and right helical screws to rotate, which drives the clamping block to clamp the workpiece. Then, the sliding mechanism moves the moving plate, which drives the workpieces on the clamp to be welded one by one. Multiple batteries can be fed in a single operation, reducing the number of feeding and changing operations and improving the production speed. Attached Figure Description
