Description

Technical Field

[0001] This utility model relates to the field of power battery production technology, and in particular to a power battery side plate welding equipment. Background Technology

[0002] A power battery is a power source that provides power to tools, often referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. It is primarily distinguished from the starter battery used to start car engines. Common types include valve-sealed lead-acid batteries, open-type tubular lead-acid batteries, and lithium iron phosphate batteries.

[0003] The side panels of power batteries need to be welded using welding equipment during processing. However, it is often difficult to achieve the angular positioning and the position of the side panels during welding, which makes welding errors easy to occur. Therefore, we propose a power battery side panel welding equipment to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where it is often difficult to achieve the angle positioning and position limitation of the side plate when welding side plates, which makes welding errors easy to occur during the welding process. Therefore, this invention proposes a power battery side plate welding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power battery side plate welding device includes a base, a first positioning frame fixedly mounted on the top of the base, a second positioning frame connected to one side of the first positioning frame via two connecting mechanisms, multiple guide wheels symmetrically rotatably connected to both the first and second positioning frames, a first sliding cover fixedly mounted on the top of both the first and second positioning frames, and adjusting plates slidably connected inside the first sliding covers, with one side of each adjusting plate extending to one side of the first and second positioning frames respectively, and movable holes provided on the adjusting plates. The welding device also includes:

[0007] Two baffle mechanisms are provided, each passing through a corresponding moving hole and connected to the inner wall of the moving hole. The baffle mechanisms are used to limit the position of the battery side plate.

[0008] The welding mechanism is installed on the top of the base and the top of the welding mechanism is connected to one side of the first positioning frame. The welding mechanism is used to weld the two battery side plates.

[0009] In one possible design, the connecting mechanism includes a connecting shaft fixedly installed on one side of the first positioning frame, a connecting plate rotatably sleeved on the connecting shaft, the connecting plate being fixedly connected to the second positioning frame, a pull rod slidably connected to the connecting plate, an arc-shaped chuck fixedly installed at one end of the connecting shaft, multiple slots equally spaced on the arc-shaped chuck, a locking block fixedly installed at one end of the pull rod, the locking block being movably engaged with the multiple slots respectively, and a first compression spring sleeved on the pull rod, the two ends of the first compression spring being fixedly connected to the connecting plate and the locking block respectively.

[0010] In one possible design, a support plate is fixedly installed on the bottom side of the first positioning frame and the bottom side of the second positioning frame, and a second sliding cover is fixedly installed on the top of the support plate. The bottom of the adjusting plate extends into the corresponding second sliding cover and slides in connection with the inner wall of the second sliding cover. Multiple insertion holes are evenly spaced on the support plate, and the material blocking mechanism is movably engaged with the corresponding multiple insertion holes.

[0011] In one possible design, the baffle mechanism includes a limiting ring that passes through the corresponding moving hole and is slidably connected to the inner wall of the moving hole. A baffle is slidably connected laterally through the limiting ring. The baffle is used to block and limit the battery side plate. A first magnet is fixedly installed on the top of the limiting ring, and a second magnet is fixedly installed on one side of the top of the baffle. The first magnet and the second magnet attract each other.

[0012] In one possible design, the material blocking mechanism further includes a plug rod fixedly installed on one side of the bottom of the limiting ring. The plug rod is movably engaged with a plurality of corresponding insertion holes. A second compression spring is sleeved on the plug rod. The top and bottom ends of the second compression spring are fixedly connected to one side of the adjusting plate and the plug rod, respectively.

[0013] In one possible design, the welding mechanism includes a drive motor fixedly mounted on the top of the base, a drive gear fixedly mounted on the output shaft of the drive motor, a screw rotatably connected to one side of the first positioning frame, a threaded plate threaded onto the screw, a limit rod slidably connected through the threaded plate, the limit rod fixedly mounted on one side of the first positioning frame, a driven gear fixedly mounted at the bottom end of the screw, the drive gear meshing with the driven gear, a welding gun fixedly mounted on the top side of the threaded plate, and the welding gun connected to an external welding machine.

[0014] In this application, firstly, the second positioning frame is rotated and adjusted according to the angle required for welding the two battery side panels. The second positioning frame is rotated to a predetermined angle. After rotational adjustment, two pull rods can be released simultaneously. The first compression spring, under stress, can push the locking block to move into the corresponding slot, allowing the locking block to engage with the arc-shaped chuck, thus positioning the second positioning frame. This allows the two battery side panels to be welded at a suitable angle. Then, the two battery side panels to be welded can be placed sequentially on the first and second positioning frames. Next, two adjusting plates can be pushed laterally to adjust the lateral position of the baffle. After adjusting the position of the adjusting plates, the baffle can be pushed to engage with the arc-shaped chuck. The other side of the battery side panel contacts each other, and the first and second magnets attract each other to limit the position of the baffle. The baffle can stably limit the position of the battery side panel. When the baffle is released, the second compression spring under force can push the plug rod downward to insert the plug rod into the corresponding hole, thereby positioning the adjustment plate and limiting the lateral position of the baffle. The two baffles limit the two battery side panels respectively. Then, the welding gun is started, and the drive motor is started to drive the drive gear to rotate. At this time, under the meshing transmission action with the driven gear, the screw can be driven to rotate. When the screw rotates, under the thread transmission action with the threaded plate, the welding gun can be driven to move longitudinally, thereby connecting the splice seam of the two battery side panels.

[0015] Beneficial effects: In this utility model, the power battery side plate welding equipment can be rotatably connected by a connecting shaft and a corresponding connecting plate through a connecting mechanism, which can realize the rotational support of the second positioning frame. This allows for the adjustment of the angle between the first and second positioning frames. After adjustment, the pull rod can be released, and the first compression spring under force can push the locking block to move into the corresponding slot, so that the locking block can be engaged with the arc-shaped chuck, thereby positioning the second positioning frame. This allows the two battery side plates to be welded at a suitable angle when welding them.

[0016] In this utility model, the power battery side plate welding equipment can, through the material blocking mechanism, adjust the lateral position of the adjusting plate. After the battery side plate is moved to the welding position, the baffle can be pushed so that the baffle contacts the other side of the battery side plate. At the same time, the baffle can be limited by the attraction of the first magnet and the second magnet, so that the baffle can be stably limited by the baffle.

[0017] After the lateral position of the adjusting plate is adjusted, the baffle can be released. The second compression spring, which is under force, can push the insert rod downward so that the insert rod is inserted into the corresponding insertion hole. This can position the adjusting plate and limit the lateral position of the baffle.

[0018] In this utility model, the power battery side plate welding equipment, through the welding mechanism, can start the welding gun after the two battery side plates to be welded are joined together, and at the same time start the drive motor to drive the active gear to rotate. At this time, under the meshing transmission action with the driven gear, the screw can be driven to rotate. When the screw rotates, under the thread transmission action with the thread plate, the welding gun can be driven to move longitudinally, thereby connecting the splice seam of the two battery side plates.

[0019] This invention allows for the rotation and adjustment of the second positioning frame, thereby ensuring that the two battery side plates are stably connected at a fixed angle when the first and second positioning frames are used to support and position them. This facilitates welding of the battery side plates without welding errors, resulting in excellent operational stability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figure 1-3 A welding device mainly includes a base 1. The top of the base 1 is made of Q235 steel plate (20mm thick, flatness ≤0.1mm / m) on which a first positioning frame 2 is securely mounted. One side of the first positioning frame 2 is connected to the same second positioning frame 5 via two connecting mechanisms. Each of these connecting mechanisms includes a connecting shaft 3 fixedly mounted on one side of the first positioning frame 2. The connecting shaft 3 is made of 40Cr tempered steel (HRC45-50), and a connecting plate 4 is rotatably sleeved on the connecting shaft 3. The connecting plate 4 is fixedly connected to the second positioning frame 5. In this way, the second positioning frame 5 can rotate relative to the first positioning frame 2.

[0026] Multiple guide wheels 6 are symmetrically rotatably connected to both the first positioning frame 2 and the second positioning frame 5 to assist in the movement and positioning of the battery side plate. First sliding covers 7 are fixedly installed on the top of both the first positioning frame 2 and the top of both the second positioning frame 5. Adjusting plates 8 are slidably connected inside the first sliding covers 7, with one side of each adjusting plate 8 extending to one side of the first positioning frame 2 and one side of the second positioning frame 5, respectively. The adjusting plates 8 have movable holes to prepare for the subsequent installation of a material-blocking mechanism.

[0027] The baffle mechanism is configured as follows: two baffle mechanisms pass through corresponding moving holes and are connected to the inner wall of the moving holes. Each baffle mechanism includes a limiting ring 15, and a baffle 16 is laterally slidably connected inside the limiting ring 15 to block and limit the battery side plate. A first magnet 17 is fixedly installed on the top of the limiting ring 15, and a second magnet 18 is fixedly installed on one side of the top of the baffle 16. The first magnet 17 and the second magnet 18 can attract each other (they are N35 neodymium iron boron permanent magnets), thereby fixing the position of the baffle 16.

[0028] In addition, a rod 19 is fixedly installed on one side of the bottom of the limiting ring 15. The rod 19 can be inserted into any one of the multiple holes on the corresponding support plate 9 to position the adjusting plate 8. A second compression spring 20 is sleeved on the rod 19. The top and bottom ends of the second compression spring 20 are fixedly connected to one side of the adjusting plate 8 and the rod 19, respectively. After the position of the adjusting plate 8 is adjusted, the baffle 16 is released, and the second compression spring 20 pushes the rod 19 downward to insert it into the corresponding hole, thereby positioning the adjusting plate 8.

[0029] The specific working principle of the connecting mechanism is as follows: An arc-shaped chuck 12 (made of GCr15 bearing steel, surface hardened to HRC58-62) is fixedly installed at one end of the connecting shaft 3. Multiple slots are evenly spaced on the arc-shaped chuck 12. A pull rod 11 is slidably connected to the connecting plate 4. A locking block 13 is fixedly installed at one end of the pull rod 11, and the locking block 13 can be movably engaged with any one of the multiple slots. A first compression spring 14 is sleeved on the pull rod 11, and both ends of the first compression spring 14 are fixedly connected to the connecting plate 4 and the locking block 13, respectively. When it is necessary to adjust the angle of the second positioning frame 5, the pull rod 11 can be pulled to disengage the locking block 13 from the slot, and then the second positioning frame 5 can be rotated to the appropriate angle. After adjustment, the pull rod 11 is released, and the first compression spring 14 will push the locking block 13 to move into the corresponding slot, thereby positioning the second positioning frame 5.

[0030] This application can be used in the field of power battery production technology, or in other fields applicable to this application.

[0031] Example 2: Reference Figure 1 Based on Embodiment 1, an improvement is made to a power battery side plate welding device, which is applied to the field of power battery production technology. The welding mechanism is configured as follows: The welding mechanism is installed on the top of the base 1, and its top is connected to one side of the first positioning frame 2. The welding mechanism includes a drive motor 25 fixedly installed on the top of the base 1, and a drive gear 26 is fixedly installed on the output shaft of the drive motor 25. A screw 21 is rotatably connected to one side of the first positioning frame 2, and a threaded plate 23 is threadedly fitted on the screw 21. A limit rod 22 is slidably connected through the threaded plate 23, and the limit rod 22 is fixedly installed on one side of the first positioning frame 2 to limit the rotation of the threaded plate 23. A driven gear 27 is fixedly installed at the bottom end of the screw 21, and the drive gear 26 meshes with the driven gear 27. A welding gun 24 is fixedly installed on one side of the top of the threaded plate 23, and the welding gun 24 is connected to an external welding machine.

[0032] After the two battery side panels to be welded are joined together, the welding torch 24 is started, and the drive motor 25 is started to drive the drive gear 26 to rotate. Under the meshing transmission action with the driven gear 27, the screw 21 will rotate. When the screw 21 rotates, under the thread transmission action with the threaded plate 23, the welding torch 24 will move longitudinally, thereby welding the splice seam of the two battery side panels.

[0033] A support plate 9 is fixedly installed on the bottom side of both the first positioning frame 2 and the bottom side of both the second positioning frame 5. A second sliding cover 10 is fixedly installed on the top of the support plate 9, and the bottom of the adjusting plate 8 extends into the corresponding second sliding cover 10 and slides in connection with the inner wall of the second sliding cover 10. In this way, the second sliding cover 10 can slide and limit the adjusting plate 8, enabling it to maintain lateral linear movement, thereby facilitating the adjustment of the lateral position of the material blocking mechanism.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the welding torch 24 and the drive motor 25 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
