Description

Technical Field

[0001] This utility model relates to the field of spot welding technology, specifically to an automatic shell-inserting spot welding machine. Background Technology

[0002] With the continuous development of the new energy industry, the lithium battery industry has made great progress and is widely used. In the production process of lithium batteries, the cells need to be installed into a casing, and then the lithium batteries are welded together using a spot welding machine, thus completing the assembly and welding of the lithium battery.

[0003] In existing lithium battery spot welding technologies, the process typically involves manually placing the lithium battery cell into the casing, then adding a nickel sheet, and finally welding. For example, an automatic lithium battery spot welding machine and its feeding mechanism (patent publication number CN114918523A) works by placing a material frame containing the battery on top of a moving base. The material frame slides along a moving groove to one end of the moving base, while a nickel sheet is placed inside a storage slot. A controller controls the feeding device, nickel loading device, and spot welding mechanism to feed the battery top and nickel sheet, and then performs spot welding. The nickel sheet welding at the bottom of the battery improves the efficiency of electric welding of the battery and nickel sheet, and improves the spot welding efficiency of lithium battery packs. However, the device still has some problems: for example, before the lithium battery is placed into the material frame, the cell still needs to be manually placed into the casing. Then the material frame containing the lithium battery after casing is placed on the top of the moving base. Considering that a certain degree of accuracy needs to be ensured when placing the lithium battery cell into the casing to avoid damage to the cell, manually placing the cell into the casing and then applying nickel and spot welding is a cumbersome operation that consumes a lot of time and effort. Therefore, an automatic casing spot welding machine is proposed. Utility Model Content

[0004] This utility model proposes an automatic battery cell insertion and spot welding machine, which solves the problem that the existing technology requires manual insertion of battery cells into the casing, followed by nickel plating and spot welding, which is cumbersome and time-consuming.

[0005] The technical solution of this utility model is as follows: An automatic casing-inserting spot welding machine includes a spot welding machine body, which includes: a base, a feeding component, a spot welding component, and a material frame.

[0020] A sliding sleeve, which is fixedly connected to the top end of the second rotating shaft;

[0022] A connecting plate, one side of which is fixedly connected to the other end of the connecting rod;

[0023] A gripper, disposed on the other side of the connecting plate, is used to grip the battery cell.

[0024] Furthermore, the gripper includes:

[0025] A fixing frame, one side of which is fixedly connected to the connecting plate;

[0026] Connecting block one, which is fixedly connected to the other side of the fixing frame.

[0028] Threaded rod one, which is rotatably connected to connecting block one, and one end of threaded rod one is fixedly connected to the output end of the third motor;

[0035] A pivot six passes through the lower side of the irregularly shaped block and is rotatably connected to the irregularly shaped block;

[0036] A gripping block, one end of which is rotatably connected to the rotating shaft.

[0037] As a further embodiment of this application, the lateral movement component includes:

[0038] Mounting plate, which is fixedly connected to the upper side of the feeding assembly;

[0039] Two support frames are fixedly connected to the top of the mounting plate;

[0040] Threaded rod two, which is rotatably connected to the two support frames and passes through one of the support frames;

[0041] A fourth motor is mounted on the mounting plate, and the output end of the fourth motor is fixedly connected to one end of the threaded rod II.

[0043] A support plate is threadedly connected to the threaded rod, and the support plate is slidably connected to the smooth rod.

[0044] A reinforcing rod is provided, with one side of the reinforcing rod fixedly connected to the bottom of the material frame and the other side of the reinforcing rod fixedly connected to the support plate.

[0045] As a further improvement of this application, one of the support frames is provided with a groove that is adapted to the reinforcing rod.

[0046] The working principle and beneficial effects of this utility model are as follows:

[0047] In this utility model, by turning on the first motor, the conveyor belt begins to perform step-by-step transmission, and the battery cells are placed in the sequential installation slots. The battery cells are then conveyed by the conveyor belt to the area directly below the gripping block, which facilitates the sequential transport of multiple battery cells to the gripping position and prevents them from tipping over.

[0048] In this invention, the connecting rod is pushed up and down by the cylinder to move the connecting plate and the gripper up and down. The gap between the two gripping blocks is increased or decreased by the forward and reverse rotation of the third motor. The cylinder and the third motor work together to grip the battery cell and move it out of the mounting slot. The gripper moves the battery cell to the top of the housing and completes the insertion of the battery cell by the forward and reverse rotation of the second motor. This makes it easy to place the battery cell into the housing and saves manpower.

[0049] In this invention, the feeding assembly drives the material frame to move towards the spot welding assembly, positioning the next housing at the location where the next battery cell will be inserted. The gripper then picks up the battery cell and places it into the housing. This process is repeated sequentially. Once all housings in a row have been fitted with batteries, the fourth motor drives the threaded rod to rotate, causing the support plate and material frame to move away from the feeding assembly. This positions the next row of housings below the gripper, allowing the feeding assembly to place the battery cells into each housing in that row. The remaining housings are then placed into the housings sequentially. This facilitates the sequential placement of multiple batteries into each housing. High-precision fitting prevents damage to the batteries during insertion. The feeding assembly then drives the traversing assembly and material frame to move directly below the spot welding assembly, where nickel plating and spot welding are performed on the lithium batteries that have completed the insertion process, reducing the workload of the workers.

[0062] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0063] like Figures 1-5As shown, this embodiment proposes an automatic casing spot welding machine, including a spot welding machine body 1. The spot welding machine body 1 includes a base 2, a feeding component 3, a spot welding component 4, and a material frame 5. The feeding component 3 and the spot welding component 4 are both located on top of the base 2. The feeding component 3 is used to transport the material frame 5 containing the casing-completed lithium batteries to below the spot welding component 4. The spot welding component 4 is used to weld the lithium batteries in the material frame 5. The machine also includes a material conveying component, a material picking component, and a traversing component.

[0064] Considering that before spot welding lithium batteries, the lithium battery cells 7 are typically placed into the housing 6 manually, then the cells 7 and housing 6 are placed into the material frame 5, and the material frame 5 is placed on the feeding assembly 3. The feeding assembly 3 then moves the material frame 5 to the spot welding assembly 4 for spot welding. This operation involves a lot of manual work and requires considerable physical and mental effort during continuous operation. Since the cell 7 placement requires high precision, to prevent worker distraction during continuous work leading to errors in cell 7 placement, which could damage the cells and render them unusable, and to reduce worker workload, an automated placement process can be implemented. This would reduce worker workload. Therefore, a conveying assembly is installed to transport the lithium battery cells 7 to the designated location via a conveyor belt 105. Before conveying the cells 7, workers need to place them in the mounting slot 106. During the conveying process, the battery cell 7 remains vertical and is not easily tipped over, facilitating subsequent gripping and transfer. The conveying assembly is located on one side of the top of the base 2 and is used to transport the battery cell 7. The conveying assembly includes: multiple support blocks 101, a first motor 102, two rotating shafts 103, two rollers 104, a conveyor belt 105, and multiple mounting slots 106. The multiple support blocks 101 are fixedly connected to the top of the base 2, the first motor 102 is mounted on the top of the base 2, and one rotating shaft 103... Two ends are rotatably connected to two support blocks 101 respectively. One end of another rotating shaft 103 is rotatably connected to the support block 101, and the other end is fixedly connected to the output end of the first motor 102. The roller 104 is fixedly connected to the rotating shaft 103. The conveyor belt 105 is sleeved on the roller 104. Multiple mounting slots 106 are fixedly connected to the conveyor belt 105. The first motor 102 drives the rotating shaft 103 and the roller 104 to rotate, thereby driving the conveyor to perform step-by-step transmission, thus conveying the mounting slot motor core.

[0065] Considering that the conveyor belt 105 cannot directly transport the battery cell 7 into the housing 6, even though the space inside the housing 6 is slightly larger than the battery cell 7, a certain degree of accuracy must still be ensured when inserting the battery cell 7 into the housing to avoid damage. After the battery cell 7 is transported to the designated position by the material conveying component, the material picking component needs to grab the battery cell 7 and transfer it into the housing 6 of the material frame 5. The material picking component is located in the middle of the top of the base 2 and is used to grab the battery cell 7 on the material conveying component and transfer it. The material picking component includes a second motor 201, a second rotating shaft 202, a cylinder 203, a sliding sleeve 204, and a connecting rod 205. The connecting plate 206 and the gripping component are included. The second motor 201 is installed inside the base 2, and the output end of the second motor 201 passes through the base 2. The bottom of the second rotating shaft 202 is rotatably connected to the base 2. A cavity is opened inside the second rotating shaft 202, and a cylinder 203 is installed in the cavity. The sliding sleeve 204 is fixedly connected to the top end of the second rotating shaft 202. The connecting rod 205 is slidably connected to the sliding sleeve 204. One end of the connecting rod 205 is fixedly connected to the output end of the cylinder 203. One side of the connecting plate 206 is fixedly connected to the other end of the connecting rod 205. The gripping component is set on the other side of the connecting plate 206 and is used to grip the battery cell.

[0066] The gripping component includes a fixed frame 301, a connecting block 302, a third motor 303, a threaded rod 304, a connecting block 305, a rotating shaft 306, a connecting block 307, a rotating shaft 308, a rotating shaft 309, a shaped block 310, a rotating shaft 311, and a gripping block 312. One side of the fixed frame 301 is fixedly connected to the connecting plate 206, and the connecting block 302 is fixedly connected to the other side of the fixed frame 301. The third motor 303 is mounted on the connecting block 302, and the threaded rod 304 is rotatably connected to the connecting block 302. One end of the threaded rod 304 is fixed to the output end of the third motor 303. The connection is as follows: connecting block 2 305 is threaded to the lower side of threaded rod 1 304; rotating shaft 3 306 is rotatably connected to connecting block 1 302; one side of connecting block 3 307 is rotatably connected to rotating shaft 3 306; rotating shaft 4 308 is rotatably connected to connecting block 3 307; rotating shaft 5 309 is rotatably connected to connecting block 2 305; the upper side of irregular block 310 is rotatably connected to rotating shaft 3 306; the middle part of irregular block 310 is rotatably connected to rotating shaft 4 308; rotating shaft 6 311 passes through the lower side of irregular block 310 and is rotatably connected to irregular block 310; one end of gripping block 312 is rotatably connected to rotating shaft 6 311.

[0067] It should be added that before gripping the battery cell 7, the housing 6 needs to be placed in the material frame 5, and the material frame 5 has multiple mounting holes 502 that fit the housing 6, which can ensure that the housing 6 is placed vertically in the material frame 5. During the transportation of the battery cell 7, since the first motor 102 is a stepper motor, the battery cell 7 stops conveying after reaching the gripping position. The battery cell 7 is gripped by the material picking component and placed into the housing 6. During this process, the gripper holds the battery cell 7, and the output end of the cylinder 203 pushes the connecting rod 205 to rise in the sliding sleeve 204, so that the connecting plate 206 and the gripper rise a certain distance. Then, the second motor 201 works to make the rotating shaft 202 rotate. The rotating shaft 202 drives the cylinder 203, the sliding sleeve 204, the connecting rod 205, the connecting plate 206 and the gripper to rotate together. The battery cell 7 is positioned at 80 degrees, above one end of the material frame 5 and above the housing 6 that is closest to the spot welding assembly 4 and furthest from the picking assembly within the material frame 5. Then, the output end of the cylinder 203 continues to work and returns to the initial position, causing the gripped battery cell 7 to descend and the lower half of the battery cell 7 to enter the housing 6. Finally, the third motor 303 rotates in the opposite direction, causing the two gripping blocks 312 to release the battery cell 7, and the battery cell 7 enters the housing 6, completing the battery cell 7's entry into the housing. Afterward, the second motor 201 rotates in the opposite direction, causing the rotating shaft 202 to drive the cylinder 203, sliding sleeve 204, connecting rod 205, connecting plate 206, and gripping component back to the initial position. At the same time, the conveyor transports the next battery cell 7 to be gripped to the area directly below the gripping component, continuing the process of the next battery cell 7's entry into the housing.

[0068] Considering the process of placing multiple battery cells 7 into multiple housings 6, the battery cells 7 are transferred one by one from the conveyor belt 105 into the housings 6 by the picking component. Since the gripper can only rotate and move up and down through the cooperation of the second motor 201 and the cylinder 203, the position of the gripper holding and releasing the battery cells 7 is fixed. Also considering that the feeding component 3 can drive the material frame 5 closer to or further away from the spot welding component 4, from a top-down view of the device, the picking component, in conjunction with the feeding component 3, can load the battery cells 7 into one row of housings 6 within the material frame 5, but it is difficult to load the remaining battery cells 7 into the remaining housings 6. Therefore, by setting a transverse component above the feeding component 3, the material frame 5 can move up, down, left, and right from a top-down view of the cover device. The feeding component 3 and the transverse component cooperate with each other, ensuring that while the position of the gripper placing the battery cells 7 is fixed, each housing 6 is sequentially positioned below the battery cells 7. The transverse component is located above the feeding component 3 for lateral movement. Material frame 5, the transverse moving assembly includes a mounting plate 401, two support frames 402, a threaded rod 403, a fourth motor 404, two guide rods 405, a support plate 406, and a reinforcing rod 407. The mounting plate 401 is fixedly connected to the upper side of the feeding assembly 3, and the support frames 402 are fixedly connected to the top of the mounting plate 401. One support frame 402 has a groove 501 adapted to the reinforcing rod 407. The threaded rod 403 is rotatably connected to the two support frames 402 and passes through one of the support frames 407. The frame 402, the fourth motor 404 is mounted on the mounting plate 401, the output end of the fourth motor 404 is fixedly connected to one end of the threaded rod 403, the smooth rod 405 is fixedly connected to the support frame 402, the two smooth rods 405 are respectively located on both sides of the threaded rod 403, the support plate 406 is threadedly connected to the threaded rod 403, the support plate 406 is slidably connected to the smooth rod 405, one side of the reinforcing rod 407 is fixedly connected to the bottom of the material frame 5, and the other side of the reinforcing rod 407 is fixedly connected to the support plate 406;

[0069] It should be added that after placing multiple housings 6 into the mounting holes 502 of the material frame 5, the gripper then grabs the first battery cell 7 and transfers it directly above a housing 6, which is the housing 6 closest to the spot welding assembly 4 and farthest from the conveying assembly. After the battery cell 7 is placed into this housing 6, the feeding assembly 3 drives the material frame 5 to move towards the spot welding assembly 4, so that the next housing 6 is in the position where the battery cell 7 is placed, waiting for the gripper to grab the battery cell 7 and place it into the housing 6. Then, the housings are placed in sequence. After all the housings in this row have placed the battery cell 7, the fourth motor 404 drives the threaded rod 403 to rotate, so that the support plate 406 and the material frame 5 move away from the conveying assembly, so that the next row of housings 6 is below the gripper, and cooperates with the feeding assembly 3 to place the battery cell 7 into each housing 6 in this row in sequence, and then place the remaining housings 6 into the battery cell 7 in sequence.

[0070] Working principle: The automatic housing spot welding machine is placed in a suitable working location. Multiple housings 6 are placed into the mounting holes 502 in the material frame 5. Then, the first motor 102 is turned on, causing the conveyor belt 105 to start stepping transmission. The battery cells 7 are placed in the mounting slots 106 in sequence. After the battery cells 7 are conveyed by the conveyor belt 105 to the area directly below the gripper block 312, the conveyor belt 105 temporarily stops conveying. The third motor 303 rotates forward, increasing the gap between the two gripper blocks 312. Then, the output end of the cylinder 203 retracts, and the connecting rod 205 descends within the sliding sleeve 204. The gripper descends a certain distance, and then the third motor 303 reverses to reduce the gap between the two gripping blocks 312. At this point, the inner sides of the two gripping blocks 312 are in contact with and hold the battery cell 7. Subsequently, the output end of the cylinder 203 pushes the connecting block, causing the connecting plate 206, the gripper, and the battery cell 7 to rise a certain distance. Then, the second motor 201 works to rotate the second shaft 202. The second shaft 202 drives the cylinder 203, the sliding sleeve 204, the connecting rod 205, the connecting plate 206, the gripper, and the battery cell 7 to rotate 180 degrees together, so that the battery cell 7 is in the housing 6. Directly above, the output end of cylinder 203 retracts again, causing the lower side of battery cell 7 to enter housing 6. Then, the third motor 303 rotates forward to release battery cell 7, allowing it to fully enter housing 6. The material handling assembly then returns to its initial position to grab the next battery cell 7. During this process, the feeding assembly 3 drives the material frame 5 to move towards the spot welding assembly 4, positioning the next housing 6 at the position where the next battery cell 7 will enter, waiting for the gripper to grab the battery cell 7 and place it into housing 6. This process is repeated for each subsequent housing 6. Once all housings in this row have completed the insertion of battery cells 7, the fourth motor... 404 drives the threaded rod 403 to rotate, causing the support plate 406 and the material frame 5 to move away from the material conveying component, so that the next row of housings 6 are located below the gripper, and cooperate with the feeding component 3 to put the battery cells 7 into each housing 6 in this row in sequence, and put the remaining housings 6 into the battery cells 7 in sequence. When all the housings 6 in the material frame 5 are filled with battery cells 7, the fourth motor 404 reverses to drive the material frame 5 back to its original position. Then the feeding component 3 drives the transverse component and the material frame 5 to move directly below the spot welding component 4, and performs nickel plating and spot welding on the lithium battery that has completed the housing process.

[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
