Description

Technical Field

[0001] This utility model relates to the field of soldering fixture technology, specifically a lithium battery PACK soldering fixture. Background Technology

[0002] A lithium battery pack (PACK) is an energy storage device that combines multiple lithium-ion cells in series and parallel, and integrates key components such as a battery management system (BMS), thermal management system, electrical system, and protective structure. It is the core link from the cell to the end application of lithium batteries. A lithium battery pack soldering fixture is a special tooling used to fix and position the battery or connectors (such as nickel strips, copper busbars, wires, etc.) during the assembly of a lithium battery pack (PACK), and to assist manual or automated equipment in completing the welding (spot welding or soldering).

[0003] For example, a lithium battery PACK soldering fixture disclosed in authorization announcement number CN222429517U includes a positioning plate, a placement groove is formed at the top of the positioning plate, and travel grooves are formed on both sides of the top of the positioning plate located at the placement groove. A positioning component extending into the travel groove is slidably provided at the top of the positioning plate. A lithium battery is placed in the placement groove. A protective plate that contacts the lithium battery is provided between the positioning component and the positioning plate. The positioning component includes an active strip that contacts the upper surface of the positioning plate.

[0004] Although it achieves time-saving replacement of the active bar through the positioning component, it can efficiently position protection boards of different sizes, thereby improving the working efficiency of lithium battery soldering. At the same time, it can clamp and position the left and right outer walls of the lithium battery to avoid the lithium battery shifting due to external force, and ensure that the lithium battery tabs and protection boards are accurately soldered.

[0005] However, this does not solve the problem that existing soldering fixtures are generally not conducive to the convenient sequential soldering of multiple lithium batteries, are not convenient for continuous conveying and soldering, affect the labor intensity of manual labor, reduce the efficiency of batch soldering of lithium batteries, and are not convenient for adjusting the position of the tabs, which can easily lead to defects due to improper positioning, thus affecting the convenience of adjusting the position of the tabs. Utility Model Content

[0006] The purpose of this utility model is to provide a lithium battery PACK soldering fixture to solve the problems mentioned in the background art, such as the inconvenience of soldering multiple sets of lithium batteries sequentially, the inconvenience of continuous conveying and soldering, the impact on manual labor intensity, the efficiency of batch soldering of lithium batteries by the soldering fixture, the inconvenience of conveniently adjusting the position of the tabs, and the easy occurrence of defects due to improper positioning, which affects the convenience of adjusting the position of the tabs by the soldering fixture.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery PACK soldering fixture, comprising a gantry frame and a conveyor. The conveyor is located outside the gantry frame, and a movable support is installed on the side wall of the gantry frame. A control panel is installed on the side of the gantry frame away from the movable support. A collection box is located outside the conveyor, and a feeding plate is installed inside the collection box, extending to the outside of the collection box. A support frame is located outside the movable support. An L-shaped plate is installed on the side wall of the conveyor. A second belt is fitted onto the surface of the conveyor, and multiple sets of equally spaced slot blocks are installed on the surface of the second belt. A lithium battery body is placed on the surface of each slot block, and a tab body is installed at the top of each lithium battery body. A protective plate is placed inside each slot block on the side closest to the lithium battery body, and the tab bodies are in contact with the protective plate. A laser welder is installed on the side wall of the L-shaped plate, and a second cylinder is installed on the side wall of the L-shaped plate below the laser welder. A hollow pressure block is installed at the output end of the second cylinder.

[0008] Preferably, a servo motor is installed on the side wall of the movable bracket, and a threaded rod is installed at the output end of the servo motor. The threaded rod extends into the interior of the movable bracket and is movably connected thereto. A threaded block is fitted on the surface of the threaded rod, and the threaded rod is threadedly connected to the threaded block.

[0009] Preferably, a first cylinder is mounted on the side wall of the threaded block, and a support plate is mounted on the output end of the first cylinder.

[0010] Preferably, a visual inspection camera is installed at the center of the bottom end of the support plate, and gripper cylinders are symmetrically installed at the bottom end of the external support plate of the visual inspection camera.

[0011] Preferably, a stepper motor is installed inside the support frame, and a rotating shaft is installed at the output end of the stepper motor.

[0012] Preferably, the rotating shaft extends through the support frame to its exterior, and two sets of rotating shafts are movably installed on the side wall of the support frame away from the rotating shaft.

[0013] Preferably, all the rotating shafts extend through the support frame to the outside of it, and rollers are fitted on the surface of the rotating shafts inside the support frame.

[0014] Preferably, the surface of the external rotating shaft and the rotating shaft of the support frame are both fitted with a first belt, and the output end of the control panel is electrically connected to the input end of the conveyor, servo motor, first cylinder, vision inspection camera, gripper cylinder, stepper motor, laser welder, and second cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the soldering fixture not only enables the soldering fixture to conveniently and sequentially weld multiple groups of lithium batteries, facilitates continuous conveying and welding, reduces the labor intensity of manual labor, and improves the efficiency of batch welding of lithium batteries by the soldering fixture, but also facilitates the convenient adjustment of the position of the electrode tabs, avoids defects caused by improper position, and improves the convenience of adjusting the position of the electrode tabs by the soldering fixture.

[0016] (1) The conveyor drives the second belt to rotate, and the second belt drives multiple sets of slot blocks to rotate. When the slot blocks rotate to the working area, the manual person puts the protective plate into the slot block in sequence, and places the lithium battery body into the slot block in sequence, so that the electrode body at the top of the lithium battery body is placed on the surface of the protective plate. When it moves to the welding area, the conveyor is turned off and the rotation stops. The second cylinder drives the hollow pressure block to move downward. The hollow pressure block presses down the electrode body and the protective plate. The laser welder is turned on. The laser welder welds the electrode body and the protective plate by passing the laser through the hollow pressure block. After the welding is completed, the conveyor is turned on so that it continues to rotate and move. When it rotates to the position of the unloading plate, the lithium battery body, electrode body, and protective plate on the surface of the slot block are separated from the slot block by the unloading plate. They roll into the collection box for collection by the unloading plate. This realizes that the soldering fixture can conveniently weld multiple sets of lithium batteries in sequence, which facilitates continuous conveying and welding, reduces the labor intensity of manual labor, and improves the efficiency of the soldering fixture for batch welding of lithium batteries.

[0017] (2) The servo motor drives the threaded rod to rotate, which in turn moves the threaded block. This causes the threaded block to move the first cylinder, support plate, vision inspection camera, and gripper cylinder above the lithium battery body. The first cylinder then drives the support plate, vision inspection camera, and gripper cylinder to descend to the surface of the lithium battery body. The two sets of gripper cylinders then grasp the lithium battery body. Simultaneously, the vision inspection camera detects the position of the tabs on the surface of the lithium battery body. If the tabs are not directly above the surface, the servo motor is activated, causing it to drive the threaded block, first cylinder, and... The gripper cylinder, lithium battery body, and tab body move to the top of the support frame. The stepper motor drives the rotating shaft to rotate, and the rotating shaft drives the roller to rotate. The lithium battery body and tab body are placed on the surface of the roller. Under the rotation of the two sets of rollers, the lithium battery body and tab body are rotated to the top, and then the tab body is gripped and moved to the surface of the slot block for placement. This enables the soldering fixture to conveniently adjust the position of the tab, avoids defects caused by improper positioning, and improves the convenience of adjusting the position of the tab.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0029] Please see Figure 1-9This utility model provides an embodiment of a lithium battery PACK soldering fixture, comprising a gantry frame 1 and a conveyor 2. The conveyor 2 is disposed outside the gantry frame 1, and a movable support 6 is installed on the side wall of the gantry frame 1. A control panel 5 is installed on the side of the gantry frame 1 away from the movable support 6. A collection box 4 is disposed outside the conveyor 2, and a feeding plate 3 is installed inside the collection box 4, extending to the outside of the collection box 4. A support frame 7 is disposed outside the movable support 6. An L-shaped plate 8 is installed on the side wall of the conveyor 2, and a surface fitted with... The second belt 21 has multiple sets of equally spaced slot blocks 22 installed on its surface. A lithium battery body 26 is placed on the surface of each slot block 22. A tab body 27 is installed on the top of each lithium battery body 26. A protective plate 28 is placed on the side of each slot block 22 near the lithium battery body 26. The tab body 27 is in contact with the protective plate 28. A laser welder 23 is installed on the side wall of the L-shaped plate 8. A second cylinder 24 is installed on the side wall of the L-shaped plate 8 below the laser welder 23. A hollow pressure block 25 is installed at the output end of the second cylinder 24.

[0030] When using the lithium battery PACK soldering fixture, turn on conveyor 2. Conveyor 2 drives the second belt 21 to rotate, which in turn drives multiple sets of slot blocks 22 to rotate. When the slot blocks 22 rotate to the working area, manually place the protective plates 28 into the slot blocks 22 one by one. Operate control panel 5 to place the lithium battery bodies 26 into the slot blocks 22 one by one, and place the tab bodies 27 at the top of the lithium battery bodies 26 on the surface of the protective plates 28. When moving to the soldering area, turn off conveyor 2 to stop rotating, turn on the second cylinder 24, and with the support of the L-shaped plate 8, the second cylinder 24 drives the hollow pressure block 25 to move downward. The hollow pressure block 25 presses down the tab bodies 27 and the protective plates 28. Turn on the laser. Supported by the L-shaped plate 8, the laser welder 23 welds the tab body 27 and the protective plate 28 by passing the laser through the hollow pressure block 25. After welding, the second cylinder 24 drives the hollow pressure block 25 to reset and opens the conveyor 2, allowing it to continue rotating and moving. When it rotates to the position of the unloading plate 3, the lithium battery body 26, tab body 27, and protective plate 28 on the surface of the slot block 22 are disengaged from the slot block 22 by the unloading plate 3 and roll into the collection box 4 for collection. This realizes the convenient sequential welding of multiple sets of lithium batteries by the soldering fixture, facilitates continuous conveying and welding, reduces the labor intensity of manual labor, and improves the efficiency of batch welding of lithium batteries by the soldering fixture.

[0031] A servo motor 9 is installed on the side wall of the movable support 6. A threaded rod 10 is installed at the output end of the servo motor 9. The threaded rod 10 extends into the interior of the movable support 6 and is movably connected thereto. A threaded block 11 is fitted on the surface of the threaded rod 10, and the threaded rod 10 is threadedly connected to the threaded block 11.

[0032] A first cylinder 12 is installed on the side wall of the threaded block 11, and a support plate 13 is installed at the output end of the first cylinder 12.

[0033] A visual inspection camera 14 is installed at the center of the bottom end of the support plate 13, and gripper cylinders 15 are symmetrically installed at the bottom end of the external support plate 13 of the visual inspection camera 14.

[0034] A stepper motor 16 is installed inside the support frame 7, and a rotating shaft 17 is installed at the output end of the stepper motor 16;

[0035] The rotating shaft 17 extends through the support frame 7 to its outside, and two sets of rotating shafts 19 are movably installed on the side wall of the support frame 7 away from the rotating shaft 17.

[0036] All rotating shafts 19 extend through the support frame 7 to its outside, and rollers 20 are fitted on the surface of the rotating shafts 19 inside the support frame 7.

[0037] The surfaces of the external rotating shaft 19 and rotating shaft 17 of the support frame 7 are all fitted with the first belt 18. The output end of the control panel 5 is electrically connected to the input end of the conveyor 2, servo motor 9, first cylinder 12, vision inspection camera 14, gripper cylinder 15, stepper motor 16, laser welder 23, and second cylinder 24.

[0038] When the lithium battery body 26 needs to be placed, the servo motor 9 is activated. Supported by the moving bracket 6, the servo motor 9 drives the threaded rod 10 to rotate. With the threaded connection between the threaded rod 10 and the threaded block 11, the threaded rod 10 moves the threaded block 11, causing the threaded block 11 to move the first cylinder 12, support plate 13, visual inspection camera 14, and gripper cylinder 15 above the lithium battery body 26. The first cylinder 12 is then activated. Supported by the threaded block 11, the first cylinder 12 drives the support plate 13, visual inspection camera 14, and gripper cylinder 15 to descend to the surface of the lithium battery body 26. The two sets of gripper cylinders 1... 5. Two sets of gripper cylinders 15 grip the lithium battery body 26. Simultaneously, a vision inspection camera 14 detects the position of the tab body 27 on the surface of the lithium battery body 26. The detected data is transmitted via wire to an external internet computer, which performs logical analysis and processing, then transmits the data back to the control panel 5. If the tab body 27 is not detected to be directly above the surface, the control panel 5 activates the servo motor 9. This servo motor 9, through the threaded rod 10, moves the threaded block 11, the first cylinder 12, the gripper cylinders 15, the lithium battery body 26, and the tab body 27 above the support frame 7. The control panel 5 opens the first cylinder 12, which adjusts the position of the lithium battery body 26 and the tab body 27. When the lithium battery body 26 is placed on the surface of the roller 20, the gripper cylinder 15 changes from clamping to releasing the lithium battery body 26. The stepper motor 16 is turned on, and under the support of the support frame 7, the stepper motor 16 drives the rotating shaft 17 to rotate. Under the movable support of the two sets of rotating shafts 19, the rotating shaft 17 drives the rotating shaft 19 to rotate through the first belt 18. The rotating shaft 19 drives the roller 20 to rotate, placing the lithium battery body 26 and the tab body 27 on the surface of the roller 20, so that the lithium battery body 26 and the tab body 27 are positioned... The body 27 rotates to the top under the rotation of two sets of rollers 20. During rotation, the visual inspection camera 14 performs visual inspection. The control panel 5 controls the rotation speed of the stepper motor 16, and the stepper motor 16 controls the position of the lithium battery body 26 and the electrode body 27. After the electrode body 27 is aligned, the control panel 5 controls the gripper cylinder 15, the first cylinder 12, and the servo motor 9 to pick it up and move it to the surface of the slot block 22 for placement. This enables the soldering fixture to conveniently adjust the position of the electrode, avoids defects caused by improper positioning, and improves the convenience of adjusting the position of the electrode.

[0039] Working principle: Conveyor 2 drives the second belt 21 to rotate, which in turn drives multiple sets of slot blocks 22 to rotate. When the slot blocks 22 rotate to the working area, the protective plates 28 are manually placed into the slot blocks 22 one by one, followed by the lithium battery bodies 26. The electrode bodies 27 at the top of the lithium battery bodies 26 are then placed on the surface of the protective plates 28. When the machine moves to the welding area, conveyor 2 is turned off and stops rotating. The second cylinder 24 drives the hollow pressure block 25 to move downwards, pressing down the electrode bodies 27 and the protective plates 28. The laser welder 23 then uses a laser to penetrate the hollow pressure block. The hollow pressure block 25 welds the electrode body 27 and the protective plate 28. After welding, the second cylinder 24 drives the hollow pressure block 25 to reset, and opens the conveyor 2, allowing it to continue rotating and moving. When it rotates to the position of the unloading plate 3, the lithium battery body 26, electrode body 27, and protective plate 28 on the surface of the slot block 22 are disengaged from the slot block 22 by the push of the unloading plate 3, and roll down into the collection box 4 for collection. When it is necessary to place the lithium battery body 26, the servo motor 9 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the threaded block 11 to move, so that the threaded block 11 drives the first Cylinder 12, support plate 13, vision inspection camera 14, and gripper cylinder 15 move to above the lithium battery body 26. First cylinder 12 drives support plate 13, vision inspection camera 14, and gripper cylinder 15 to descend to the surface of the lithium battery body 26. Two sets of gripper cylinders 15 grip the lithium battery body 26. Simultaneously, the vision inspection camera 14 detects the position of the tab body 27 on the surface of the lithium battery body 26. Control panel 5 activates servo motor 9, causing servo motor 9 to drive threaded block 11, first cylinder 12, gripper cylinder 15, lithium battery body 26, and tab body 27 via threaded rod 10. 7. Move to above the support frame 7. Stepper motor 16 drives rotating shaft 17 to rotate. Rotating shaft 17 drives rotating shaft 19 to rotate through first belt 18. Rotating shaft 19 drives roller 20 to rotate. The lithium battery body 26 and the tab body 27 are placed on the surface of roller 20. Under the rotation of the two sets of rollers 20, the lithium battery body 26 and the tab body 27 are rotated to the top. After the tab body 27 is aligned, the control panel 5 controls the gripper cylinder 15, the first cylinder 12 and the servo motor 9 to grip and move it to the surface of the slot block 22 for placement, thus completing the use of the soldering fixture.
