Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and in particular to an auxiliary device for welding lithium battery electrode sheets. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They can be connected to each other to form a battery pack. When assembling a lithium battery pack, workers need to manually arrange the lithium batteries with the negative electrode facing up on a placement plate, place the nickel sheet on the upper surface of the lithium batteries, and finally spot weld them using a spot welding machine.

[0003] Manual welding requires placing a nickel sheet on the surface of the lithium battery electrode, and then using the welding head in a spot welding machine to spot weld a single spot multiple times. Only after completing the welding of one spot can the next spot be welded, making the welding process cumbersome.

[0004] To address these issues, a lithium battery electrode sheet welding auxiliary device is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art of spot welding a single weld point multiple times and only one weld point can be spot welded at the same time, and to propose an auxiliary device for welding lithium battery electrode sheets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lithium battery electrode sheet welding auxiliary device includes a housing, a working platform, and lithium batteries. A controller is provided on the surface of the working platform. A traversing mechanism is provided on the side of the housing facing the working platform. A lifting mechanism is provided inside the traversing mechanism. A spot welding assembly is provided on the side of the lifting mechanism facing the working platform. A strip positioning block is provided on the working platform corresponding to the spot welding assembly. Multiple lithium batteries are placed inside the strip positioning block.

[0008] Preferably, the transverse movement mechanism includes a fixed plate, which is fixedly connected to the housing. A transverse slide rail is fixedly connected to the surface of the fixed plate. A transverse movement screw is provided between the transverse slide rails. The two ends of the transverse movement screw are rotatably connected to the two sides of the fixed plate in the horizontal direction. The output end of the transverse movement screw passes through the fixed plate and is connected to a transverse movement motor. The transverse movement motor is fixedly connected to the fixed plate.

[0009] Preferably, the lifting mechanism includes a sliding mounting plate, one side of which is slidably connected to a transverse slide rail, and a longitudinal slide rail is fixedly mounted on the other side of the sliding mounting plate. A lifting screw is provided between the longitudinal slide rails, and both ends of the lifting screw in the vertical direction are rotatably connected to the sliding mounting plate. The top end of the lifting screw passes through the sliding mounting plate and is connected to a lifting motor, and the lifting motor is fixedly connected to the top end of the sliding mounting plate.

[0010] Preferably, the spot welding assembly includes a lifting slide plate, one side of which is slidably connected to a longitudinal slide rail, and the other side of which is fixedly connected to a spot welding machine, with multiple welding heads fixedly connected to the bottom of the spot welding machine.

[0011] Preferably, the strip positioning block has multiple semi-open placement slots on the side away from the housing, the shape of the placement slots matches the lithium battery, and the open side of the placement slots is adsorbed and connected to a limit cover.

[0012] Preferably, the shape of the limiting cover facing the placement groove matches the placement groove, a pull ring is fixedly connected to the other side of the limiting cover, and magnetic blocks are embedded in the limiting cover on both sides corresponding to the inner wall of the placement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the combined use of a transverse mechanism and a lifting mechanism. The lifting motor drives the lifting screw to lower the lifting slide plate, allowing the welding head of the spot welding machine to contact the surface of the lithium battery to support welding. After completing one welding action, the transverse motor drives the transverse screw to move the sliding mounting plate horizontally above the next set of lithium batteries to be welded, thereby achieving continuous welding.

[0015] 2. By setting a strip positioning block, after a welding operation is completed, the connection between the limiting cover and the placement slot can be released by the traction ring, so that the welded lithium battery can be taken out and placed in the next set without stopping the machine, thus improving work efficiency.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4 A lithium battery electrode sheet welding auxiliary device includes a housing 1, a working platform 2 and a lithium battery 3. A controller 4 is provided on the surface of the working platform 2. A transverse mechanism is provided on the side of the housing 1 facing the working platform 2. A lifting mechanism is provided inside the transverse mechanism. A spot welding component is provided on the side of the lifting mechanism facing the working platform 2. A strip positioning block 5 is provided on the working platform 2 corresponding to the spot welding component. Multiple lithium batteries 3 are placed in the strip positioning block 5.

[0023] The transverse movement mechanism includes a fixed plate 6, which is fixedly connected to the housing 1. A transverse slide rail 7 is fixedly connected to the surface of the fixed plate 6. A transverse movement screw 8 is arranged between the transverse slide rails 7. The two ends of the transverse movement screw 8 are rotatably connected to the two sides of the fixed plate 6 in the horizontal direction. The output end of the transverse movement screw 8 passes through the fixed plate 6 and is connected to a transverse movement motor 9. The transverse movement motor 9 is fixedly connected to the fixed plate 6.

[0024] The lifting mechanism includes a sliding mounting plate 10. One side of the sliding mounting plate 10 is slidably connected to the transverse slide rail 7, and the other side of the sliding mounting plate 10 is fixedly mounted with a longitudinal slide rail 11. A lifting screw 12 is arranged between the longitudinal slide rails 11. The two ends of the lifting screw 12 in the vertical direction are rotatably connected to the sliding mounting plate 10. The top end of the lifting screw 12 passes through the sliding mounting plate 10 and is connected to a lifting motor 13. The lifting motor 13 is fixedly connected to the top end of the sliding mounting plate 10.

[0025] The spot welding assembly includes a lifting slide plate 14, one side of which is slidably connected to a longitudinal slide rail 11, and the other side of the lifting slide plate 14 is fixedly connected to a spot welding machine 15.

[0026] Furthermore, a transverse threaded sleeve 16 is fixedly connected to the center of the sliding mounting plate 10 facing the transverse lead screw 8, and the transverse threaded sleeve 16 is threadedly connected to the transverse lead screw 8.

[0027] Furthermore, a longitudinal threaded sleeve 17 is fixedly connected to the center of the lifting slide plate 14 facing the lifting screw 12, and the longitudinal threaded sleeve 17 is threadedly connected to the lifting screw 12.

[0028] A further advantage of the above-mentioned method is that, through the combined use of the transverse mechanism and the lifting mechanism, the lifting motor 13 drives the lifting screw 12 to lower the lifting slide plate 14, so that the welding head 22 of the spot welding machine 15 contacts the surface of the lithium battery 3 to support welding. After completing one welding action, the transverse motor 9 drives the transverse screw 8 to move the sliding mounting plate 10 to the top of the next set of lithium batteries 3 to be welded and weld again, thereby achieving the function of continuous welding.

[0029] Furthermore, the strip positioning block 5 has multiple semi-open placement slots 18 on the side away from the housing 1. The shape of the placement slots 18 matches the lithium battery 3. The open side of the placement slot 18 is attached to a limiting cover 19. The shape of the limiting cover 19 facing the placement slot 18 matches the placement slot 18. A pull ring 20 is fixedly connected to the other side of the limiting cover 19. Magnetic blocks 21 are embedded in the limiting cover 19 on both sides of the inner wall of the placement slot 18.

[0030] It should be noted that the depth of the placement groove 18 is the same as the height of the lithium battery 3, so that the nickel sheet in the prior art can be placed on the surface of the strip positioning block 5 and the lithium battery 3.

[0031] A further advantage of the above approach is that, after a welding operation is completed, the connection between the limiting cover 19 and the placement slot 18 can be released by the traction ring 20, thereby removing the welded lithium battery 3 and placing the next set without stopping the machine, thus improving work efficiency.

[0032] Furthermore, the spot welding machine 15 is electrically connected to the housing 1, and multiple welding heads 22 are fixedly connected to the bottom of the spot welding machine 15 at the corresponding placement groove 18.

[0033] A further advantage of the above is that after the user operates the lifting slide 14 to descend via the controller 4, multiple welding heads 22 contact the nickel sheet placed on the surface of the lithium battery 3 for spot welding, thereby completing the spot welding in one go and reducing the time required to weld the nickel sheet.

[0034] When using this utility model, the operator releases all the limiting covers 19 from the placement slot 18 by pulling the pull ring 20, places the lithium battery 3 in the placement slot 18, then reconnects the limiting covers 19 to the placement slot 18 by magnetic block 21, and limits the lithium battery 3 in the placement slot 18 by the limiting covers 19. Finally, a nickel sheet is placed on the top of the lithium battery 3. After placement, the welding program is run by the controller 4.

[0035] During welding, the lifting motor 13 drives the lifting screw 12 to rotate, and through the longitudinal threaded sleeve 17, the lifting slide plate 14 slides down along the longitudinal slide rail 11, so that the welding head 22 of the spot welding machine 15 contacts the nickel sheet on the surface of the lithium battery 3. By contacting the nickel sheet placed on the surface of the lithium battery 3 with multiple welding heads 22, spot welding is completed in one go, reducing the time required to weld the nickel sheet.

[0036] After completing one welding operation, the transverse motor 9 drives the transverse lead screw 8 to rotate, and the transverse threaded sleeve 16 drives the sliding mounting plate 10 to slide along the transverse slide rail 7 to the top of the next set of lithium batteries 3 to be welded. At this time, the worker can open the limit cover 19 here through the traction ring 20 to take out the welded lithium battery 3 and place the next set of lithium batteries 3. Thus, the welded lithium battery 3 can be taken out and the next set of lithium batteries 3 can be placed without stopping the machine, which improves work efficiency.

[0037] 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.
