Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a rotary current collector welding device. Background Technology

[0002] The battery cell is the most important component of a battery. After undergoing mechanical / ultrasonic flattening, encapsulation, casing, current collector welding, and sealing welding, the battery cell can be assembled into a finished battery. An existing multi-station rotary current collector welding device (publication number CN 222176314U) reduces floor space by using a rotary table for switching between different stations, allows for simultaneous operation of different processes, and has high efficiency. The opening and closing mechanism for the clamping structure reduces malfunctions and improves efficiency. However, when fixing and limiting the current collector, the device requires opening the clamping structure. An opening and closing cylinder drives an opening and closing block to move, passing through a slot and abutting against a contour block, compressing the clamping spring and causing the contour block to move along the clamping guide rail to open. This operation requires the use of a cylinder, adding an extra power component and causing difficulties in later maintenance and repair. Utility Model Content

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

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

[0005] A rotary collector welding device includes a welding body, a cylinder vertically mounted on the welding body, a welding head mounted on the lower end of the cylinder, and a feeding mechanism disposed on the front side of the welding body for intermittently feeding the collector. The feeding mechanism provides limiting support for the collector during rotation. The feeding mechanism includes a support frame fixed to the front end of the welding body, a rotating support assembly disposed on the support frame, and limiting components for limiting the collector's position evenly distributed around the circumference of the rotating support assembly. The rotating support assembly includes a support shaft vertically mounted on the support frame, a rotating disk fixed to the upper end of the support shaft, and a rotating component connected to the upper part of the support shaft for limiting the position. The component includes a placement platform fixed to the upper end of a rotating disk. The lower end of the placement platform is recessed. A through hole is provided on the upper surface of the placement platform, penetrating the recessed platform. A sliding groove is provided on the lower part of the outer wall of the placement platform. A limiting ring is fitted on the outer side of the placement platform. A limiting semi-circular boss is provided on the inner wall of the limiting ring. A slider corresponding to the sliding groove is provided at the lower end of the inner wall of the limiting ring. A first spring is fitted on the outer side of the placement platform below the limiting ring. A piston is installed in the recessed part of the placement platform. A guide rod is fixed to the lower end of the piston. A support wheel is fixed to the lower end of the rotating disk through the guide rod. A second spring is fitted on the outer diameter of the guide rod below the rotating disk. An arc-shaped boss is fixed at the front part of the upper surface of the support frame.

[0006] Further configuration: The rotating assembly includes a worm gear fixed on a support shaft, a worm gear meshing with the worm gear is rotatably mounted on the support frame, and a servo motor is connected to one end of the worm gear.

[0007] Further details: The support shaft is rotatably connected to the support frame, the two ends of the arc-shaped boss are rounded, and the middle part is horizontal. The arc-shaped boss and the support wheel correspond to each other when the rotating disk rotates.

[0008] Further configuration: The limiting ring is slidably connected to the placement platform, and the piston is slidably connected to the placement platform.

[0009] Further details: The guide rod is slidably connected to the rotating disk, and a through hole is provided on the rotating disk on the side below the placement platform.

[0010] Further setting: When the limiting component rotates to the underside of the welding head, it corresponds directly to the vertical position of the welding head.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using the rotating support assembly and limiting assembly of the feeding mechanism, the collecting plate on the placement platform of the front limiting assembly rotates with the rotation of the rotating support assembly. As the rotating support assembly rotates, the second spring pushes the support wheel at the lower end of the guide rod to gradually move from the upper side of the arc-shaped boss to the support frame. The guide rod pulls the piston to move downward in the placement platform. A negative pressure suction is formed on the collecting plate above the piston in the placement platform, which fixes the collecting plate. The plate is then moved to the lower side of the welding head for welding. This achieves the limiting and fixing of the collecting plate during rotation, reduces the need for limiting power components, and lowers the maintenance requirements later.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, a rotary manifold welding device includes a welding body 11, a cylinder 12 vertically mounted on the welding body 11, a welding head 13 mounted on the lower end of the cylinder 12, and a feeding mechanism disposed on the front side of the welding body 11 for intermittently feeding the manifold. The feeding mechanism provides limiting support for the manifold during rotation.

[0026] In this embodiment: the feeding mechanism includes a support frame 21 fixed at the front end of the welding body 11. A rotating support assembly is provided on the support frame 21. Limiting components for limiting the flow collector are evenly distributed around the circumference of the rotating support assembly. When the limiting components rotate to the lower side of the welding head 13, they are directly aligned with the welding head 13.

[0027] The rotating support assembly includes a support shaft 22 vertically mounted on a support frame 21. A rotating disk 23 is fixed to the upper end of the support shaft 22. A rotating component is connected to the upper part of the support shaft 22. The support shaft 22 is rotatably connected to the support frame 21. The rotating component includes a worm gear 24 fixed on the support shaft 22. A worm 25 meshing with the worm gear 24 is rotatably mounted on the support frame 21. One end of the worm 25 is connected to a servo motor 26. The servo motor 26 drives the worm 25 to mesh with the worm gear 24 and rotate, so that the worm gear 24 drives the support shaft 22 and the rotating disk 23 to rotate as a whole on the support frame 21. After rotating to a set angle, the welding head 13 corresponds to the lower limiting component. The rotation angle is calculated according to the number of set limiting components. The rotation amount of the servo motor 26 is controlled by an external controller to control the rotation angle (not shown in the figure). This technology is prior art to those skilled in the art and will not be described in detail here.

[0028] The limiting assembly includes a placement platform 27 fixed to the upper end of the rotating disk 23. The lower end of the placement platform 27 is recessed, and a through hole penetrating the recess is provided on the upper surface of the placement platform 27. A sliding groove 271 is provided on the lower part of the outer wall of the placement platform 27. A limiting ring 28 is sleeved on the outer side of the placement platform 27. A limiting semi-circular boss is provided on the inner wall of the limiting ring 28. A slider 281 corresponding to the sliding groove 271 is provided at the lower end of the inner wall of the limiting ring 28. The outer side of the placement platform 27 is sleeved below the limiting ring 28. A first spring 29 is provided. A piston 210 is installed inside the recessed platform of the placement platform 27. A guide rod 211 is fixed to the lower end of the piston 210. A support wheel 213 is fixed to the lower end of the guide rod 211 through the rotating disk 23. A second spring 212 is sleeved on the outer diameter of the guide rod 211 below the rotating disk 23. An arc-shaped boss 201 is fixed to the front of the upper end face of the support frame 21. The arc-shaped boss 201 has rounded transitions at both ends and a horizontal middle part. The arc-shaped boss 201 and the support... Wheel 213 corresponds to the rotating disk 23; limiting ring 28 is slidably connected to placement platform 27, piston 210 is slidably connected to placement platform 27; guide rod 211 is slidably connected to rotating disk 23, and a through hole is opened on the rotating disk 23 on the lower side of placement platform 27. When the collecting plate is placed on placement platform 27 at the foremost side of rotating disk 23, the rotational support assembly causes the second spring 212 to push the support wheel 213 at the lower end of guide rod 211 from the arc-shaped convex shape. The upper side of the platform 201 moves to the support frame 21, and the guide rod 211 pulls the piston 210 to move downward in the placement platform 27. The placement platform 27, located above the piston 210, forms a negative pressure suction on the collector plate to fix it. When the limiting component rotates to the lower side of the welding head 13, the cylinder 12 pushes the welding head 13 to move downward. The push limiting ring 28 moves downward with the cooperation of the slider 281 and the slide groove 271 until the welding head 13 completes the welding of the collector plate.

[0029] The working principle and usage process of this utility model are as follows: The collector plate is placed on the placement platform 27 at the front of the rotating disk 23. The outer ring of the collector plate is limited and guided by the limiting ring 28. Then, the servo motor 26 drives the worm gear 25 to mesh and rotate with the worm wheel 24. The worm wheel 24 drives the support shaft 22 and the rotating disk 23 to rotate on the support frame 21. The second spring 212 on the outside of the guide rod 211 pushes the support wheel 213 to move downward and contact the support frame 21. This causes the guide rod 211 to pull the piston 210 to move downward in the placement platform 27. The negative pressure suction formed on the upper side of the piston 210 in the placement platform 27 is formed to fix the collector plate. When the limiting component rotates to the lower side of the welding head 13, the cylinder 12 pushes the welding head 13 to move downward. The limiting ring 28 is pushed downward with the cooperation of the slider 281 and the groove 271 until the welding head 13 completes the welding of the collector plate.

[0030] 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.
