Description

Technical Field

[0001] This invention relates to the field of battery cell production and processing, and in particular to a battery cell production and processing apparatus for lithium iron phosphate batteries. Background Technology

[0002] Lithium iron phosphate batteries, as a commonly used type of lithium-ion battery, have been widely used in many fields such as new energy vehicles, energy storage equipment, and outdoor power supplies due to their significant advantages such as high safety, long cycle life, and environmental friendliness and non-toxicity.

[0003] To meet the diverse application scenarios of lithium battery packs, copper or nickel sheets are typically used to weld the individual lithium battery packs in series during the assembly process. This ensures a stable connection between the cells and meets a wide range of application requirements.

[0004] However, current lithium battery pack series welding work usually involves fixing the external fixing device of the lithium battery pack to the welding platform, and then using a welding gun to spot weld the positive and negative electrodes of the lithium battery pack in series through copper or nickel sheets.

[0005] When welding multiple lithium battery packs in a batch, it is often necessary to repeatedly disassemble and weld them sequentially. However, this welding method cannot guarantee the continuity of the welding work, so the welding efficiency needs to be improved. At the same time, when manually using a welding platform to repeatedly disassemble and reassemble multiple lithium battery packs in a batch, there are slight deviations in the manual operation or clamping equipment, which makes it impossible to guarantee a constant clamping force. When the clamping force is too small, the lithium battery pack is not effectively limited, which affects the welding quality. When the clamping force is too large, it is easy to damage the lithium battery. Summary of the Invention

[0006] In view of the above problems, this application provides a lithium iron phosphate battery cell manufacturing and processing apparatus to solve the problems existing in the series welding of lithium battery packs.

[0035] The following is in conjunction with the appendix Figure 1-13 This application will now be described in further detail.

[0036] Please refer to the reference. Figure 1 and Figure 13 A lithium iron phosphate battery cell manufacturing and processing apparatus includes a support mechanism 1 on which a lithium battery pack 6 is placed. A belt conveyor 2 is provided on the support mechanism 1. Alignment parts 3 for limiting the lithium battery pack 6 are symmetrically arranged on the left and right sides of the belt conveyor 2. C-shaped shells 4 with downward openings are symmetrically arranged on the support mechanism 1. A welding part 5 is provided between the two C-shaped shells 4.

[0037] Please refer to the reference. Figure 1 and Figure 2 The supporting mechanism 1 includes a C-shaped support plate 11 with the opening facing downward. A strip support plate 12 and a trapezoidal limiting plate 121 are symmetrically fixed on the horizontal section of the C-shaped support plate 11. The trapezoidal limiting plate 121 is fixed on the upper end face of the strip support plate 12. The upper ends of the strip support plate 12 and the trapezoidal limiting plate 121 are provided with a connected mounting groove near the rear side corresponding to the opening of the C-shaped shell 4. The inclined surface of the trapezoidal limiting plate 121 is set facing forward, and a roller is rotatably set at the corner of the inclined surface of the trapezoidal limiting plate 121.

[0038] Please refer to the reference. Figure 2 and Figure 4The belt conveyor 2 includes a conveyor belt 21 driven by an external motor. The conveyor belt 21 is mounted on a U-shaped support plate 11 by two front and rear conveyor rollers, and multiple trapezoidal telescopic plates 22 are evenly distributed on the end face of the conveyor belt 21 for moving the lithium battery pack 6.

[0039] Please refer to the reference. Figure 1 and Figure 13 The lithium battery pack 6 is placed in the limiting housing 61. T-shaped limiting blocks 62 are fixedly installed on the front and rear side walls of the limiting housing 61 in an alternating manner. Mounting grooves 2 are provided on the left and right inner side walls of the limiting housing 61. A clamping block 63 for adaptive limiting and clamping of the lithium battery pack 6 is fixedly installed inside the mounting groove 2 by a spring.

[0040] In practice, the lithium battery pack 6 is first placed into the limiting housing 61, and the lithium battery pack 6 is self-adaptively pressed against by the two clamping blocks 63 inside the limiting housing 61. Then, the lithium battery pack 6 placed in the limiting housing 61 is transported to the strip support plate 12 by an external conveying device. Then, the external motor is started to drive the conveyor belt 21 and the trapezoidal telescopic block 22 to run. At this time, the lithium battery pack 6 located above the strip support plate 12 moves along the length direction of the strip support plate 12 under the push of the trapezoidal telescopic block 22. When the lithium battery pack 6 moves to the corner of the trapezoidal limiting plate 121, the position of the lithium battery pack 6 is adjusted by the roller on the trapezoidal limiting plate 121 so that the center line of the limiting housing 61 in the front-back direction and the center line of the conveyor belt 21 are on the same vertical plane. The conveyor belt 21 and the trapezoidal telescopic block 22 continue to push the lithium battery pack 6 to move between the two alignment parts 3.

[0041] Please refer to the reference. Figure 1 and Figure 2 The alignment part 3 includes an L-shaped support block 31 that slides horizontally through the C-shaped support plate 11. The L-shaped support block 31 is provided with an alignment group 32 for aligning and clamping the lithium battery pack 6, and the L-shaped support block 31 is also provided with a drive adjustment group 33 for controlling its movement.

[0042] Please refer to the reference. Figure 5 and Figure 6 The vertical section of the L-shaped support block 31 has a sliding groove 311 symmetrically formed on one side wall near the U-shaped support plate 11. A sliding through groove 312 that penetrates the end face of the L-shaped support block 31 is formed between the two sliding grooves 311. A second sliding groove 313 is also formed on the vertical section of the L-shaped support block 31. The second sliding groove 313 is located on the side away from the U-shaped support plate 11 and is connected to the sliding groove 311 at the rear end.

[0043] Please refer to the reference. Figure 2The alignment group 32 includes a connecting block 321 that is slidably disposed in two sliding grooves 311 by two sliding blocks. The front and rear side walls of the connecting block 321 are symmetrically provided with strip slide rails 322. The alignment group 32 also includes an incline alignment claw 323 with its opening facing the welding part 5 and disposed inside the mounting groove. The incline alignment claw 323 is rotatably disposed on the side wall of the connecting block 321 away from the L-shaped support block 31. A rotating roller that rotatably passes through the connecting block 321 and the sliding through groove 312 is fixedly disposed on the end face of the incline alignment claw 323. An adjusting gear 324 is fixedly disposed on the other end of the rotating roller.

[0044] Please refer to the reference. Figure 7 The two horizontal sections of the C-shaped alignment claw 323 are close to each other and have a sliding groove on one side wall corresponding to the T-shaped limiting block 62. The side wall of the horizontal section behind the C-shaped alignment claw 323 is also fixedly provided with a strip telescopic plate 3231 for blocking the lithium battery pack 6.

[0045] Please refer to the reference. Figure 1 , Figure 3 and Figure 6 The drive adjustment assembly 33 includes a mounting plate 331 fixedly disposed between two C-shaped support plates 11. A dual-axis motor 332 is fixedly disposed on the upper end face of the mounting plate 331. The two output shafts of the dual-axis motor 332 are respectively fixedly disposed with threaded rods 334 with opposite rotation directions and rotatably connected to the side wall of the corresponding C-shaped support plate 11. The outer walls of the two threaded rods 334 are respectively threadedly connected to the horizontal section of the corresponding L-shaped support block 31. The drive adjustment assembly 33 also includes a telescopic push rod 335 slidably disposed inside the sliding groove 311 via a sliding block. An adjusting rack 336 is fixedly disposed on the telescopic section of the telescopic push rod 335. The adjusting rack 336 is also slidably disposed in the sliding groove 311 via a sliding block and is located above the telescopic push rod 335. An L-shaped linkage block 337 fixed to the lower end face of the connecting block 321 is also fixedly disposed on the sliding block.

[0046] When the lithium battery pack 6 is pushed backward between the two mounting slots and blocked by the two strip telescopic plates 3231, the power supply of the external motor is disconnected. Then, the dual-axis motor 332 is started to drive the threaded rods 334 on both sides to rotate synchronously. The L-shaped bearing blocks 31 on both sides move closer synchronously under the action of the threaded rods 334 with opposite rotation directions. The C-shaped alignment claws 323 located inside the mounting slot also move closer synchronously under the push of the L-shaped bearing blocks 31 and the connecting block 321. When the two C-shaped alignment claws 323 move closer synchronously, they gradually slide into the corresponding sliding grooves 3232 through the T-shaped limiting blocks 62 on both sides, thereby completing the alignment and clamping work of the limiting housing 61 and the lithium battery pack 6.

[0047] It should be noted that, for reference Figure 4and Figure 7 When the two chamfered aligning claws 323 approach each other, their lower ends gradually engage with the inclined surface of the trapezoidal telescopic block 22, thereby causing the telescopic section of the trapezoidal telescopic block 22 to be compressed back by the chamfered aligning claws 323. At the same time, when the two chamfered aligning claws 323 approach each other, the strip telescopic plates 3231 provided on the two chamfered aligning claws 323 will push against each other and retract into the corresponding chamfered aligning claws 323.

[0048] Please refer to the reference. Figure 8 and Figure 9 The two C-shaped shells 4 are provided with a sliding groove 3 41 on one side wall that is close to each other. Inside the sliding groove 3 41, a C-shaped sliding frame 42 with its opening facing downward is slidably arranged by an electric slider. Several teeth are fixedly arranged on one side wall of the two vertical sections of the C-shaped sliding frame 42 that are close to each other. Adjusting racks 2 44 with their lower ends penetrating through the C-shaped shell 4 are symmetrically arranged in the sliding groove 3 41. Adjusting gears 2 43 are symmetrically arranged in the sliding groove 3 41 that rotate in the front and back. The adjusting gears 2 43 are respectively meshed with the teeth on the corresponding adjusting racks 2 44 and the C-shaped sliding frame 42. The lower ends of the two adjusting racks 2 44 are fixedly arranged with inverted L-shaped sliding blocks 441. The other ends of the two inverted L-shaped sliding blocks 441 are respectively slidably arranged in the corresponding strip slide rails 322 by T-shaped sliders.

[0049] Please refer to the reference. Figure 9 , Figure 10 , Figure 11 and Figure 12 The welding part 5 includes a cross-shaped support plate 51 whose left and right ends are fixedly connected to the two sides of the C-shaped sliding frame 42. The upper end face of the cross-shaped support plate 51 is fixedly provided with a telescopic push rod 52 that passes through its end face. The telescopic section of the telescopic push rod 52 is fixedly provided with a strip pressure plate 53 that extends in the front-back direction and has a strip sliding groove 531 on its lower end face. The front and rear side walls of the cross-shaped support plate 51 are fixedly provided with a mounting frame 54 through a connecting plate. The mounting frame 54 is slidably provided with a sliding plate 55 through an electric slider. The lower end face of the sliding plate 55 is provided with two spot welding groups. Each group is provided with several spot welding heads 56. The upper end of one group of spot welding heads 56 passes through the sliding plate 55 and is connected to a mating pressure plate 57. The upper end of the mating pressure plate 57 is slidably provided in the strip sliding groove 531 through a T-shaped slider.

[0050] After the C-shaped alignment claws 323 on both sides limit and clamp the lithium battery pack 6, the electric slider inside the sliding groove 41 drives the cross-shaped support plate 51 to move downward through the C-shaped sliding frame 42. Several teeth on the two C-shaped sliding frames 42 mesh with the corresponding adjusting gears 43, causing the adjusting gears 43 to rotate. At this time, the adjusting rack 44 inside the C-shaped housing 4 moves upward under the meshing of the adjusting gears 43, and drives the connecting block 321 to slide upward along the sliding groove 311 through the inverted L-shaped sliding block 441. When the connecting block 321 slides upward, the telescopic push rod 335 and the adjusting rack slide upward along the sliding groove 311 under the drive of the L-shaped linkage block 337 until the lithium battery pack 6 and the two sets of welding heads 56 approach each other to the designated welding position.

[0051] As the lithium battery pack 6 and the cross-shaped support plate 51 approach each other, the welding pieces to be welded are placed on the lithium battery pack 6 by an external automatic welding piece feeding machine. Then, two sets of spot welding heads 56 perform series welding on the positive and negative electrodes of the lithium battery pack 6. After the positive and negative electrodes of one set of lithium batteries are welded, the electric sliders on both sides of the sliding plate 55 are controlled to move the sliding plate 55 and the mating pressure plate 57 backward, and the external welding piece feeding machine performs series welding on the positive and negative electrodes of the next set of lithium batteries. Repeating the above steps can complete the series welding of the positive and negative electrodes on one side of the lithium battery pack 6.

[0052] It should be noted that there is a certain height difference between the positive and negative electrodes of the lithium battery pack 6. Therefore, the initial positions of the two sets of spot welding heads 56 are different. That is, the height of the set of spot welding heads 56 above the negative electrode lithium battery is slightly lower than that of the other set of spot welding heads 56, and the set of spot welding heads 56 above the negative electrode lithium battery is connected to the mating pressure plate 57.

[0053] After the positive and negative electrodes of the lithium battery pack 6 are connected in series on one side, the telescopic push rod 335 inside the sliding groove 313 drives the adjusting rack 336 to extend. The adjusting rack 336 meshes with the adjusting gear 324, causing the adjusting gear 324 and the C-shaped alignment claw 323 to rotate. The lithium battery pack 6 inside the C-shaped alignment claw 323 also rotates. At this time, the positions of the positive and negative electrodes of the lithium battery pack 6 are opposite to the initial positions. Then, the telescopic push rod 52 drives the strip pressure plate 53 and the mating pressure plate 57 to retract, so that the height of one set of spot welding heads 56 on the mating pressure plate 57 is higher than that of the other set of spot welding heads 56. Then, the above welding is repeated. The steps complete the series welding of the positive and negative electrodes on the second side of the lithium battery. After welding, the telescopic push rod 335 is retracted and drives the C-shaped alignment claw 323 and the lithium battery pack 6 to flip to the initial position. The electric slider inside the sliding groove 41 drives the cross-shaped support plate 51 to move upward. At the same time, the lithium battery pack 6 moves downward to the strip support plate 12 through the meshing of the adjusting gear 43 and the adjusting rack 44. Finally, the dual-axis motor 332 is reversed. When the C-shaped alignment claws 323 on both sides move away synchronously, the trapezoidal telescopic block 22 gradually extends. Then, the external motor is started to continue to push the welded lithium battery pack 6 to the next processing area by the trapezoidal telescopic block 22.
