Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and in particular to a cell bracket assembly system for a lithium battery pack production line for electric motorcycles. Background Technology

[0002] With increasing global attention to environmental protection and sustainable energy development, electric motorcycles, with their green, environmentally friendly, convenient, and flexible characteristics, have become the preferred mode of transportation for more and more people, leading to a rapid increase in market demand. Lithium batteries, as the core power source of electric motorcycles, provide crucial support for the vehicle's normal operation. Their performance and quality directly determine important indicators such as the electric motorcycle's range, safety performance, and lifespan.

[0003] In the production and manufacturing process of lithium batteries, the cell support plays a crucial role. It not only securely fixes the cells to prevent them from shaking or shifting during vehicle operation, but also provides the necessary electrical connection channels for the cells to ensure stable current transmission. At the same time, it has good heat dissipation function to ensure that the temperature of the lithium battery is within a reasonable range during operation, thereby ensuring the overall stability and safety of the lithium battery operation.

[0004] Taking the automatic assembly equipment for the cell bracket of the power lithium battery PACK line with the publication number CN108767149A as an example, the equipment uses multiple sets of assembly and handling clamping parts with non-adjustable spacing, and cooperates with the drive end of the assembly and handling clamping cylinder to realize the three-point clamping of the cell, so that multiple cells can be clamped and assembled onto the lower bracket simultaneously. However, when clamping cells of different sizes, the spacing between the center lines of adjacent cells cannot be automatically adjusted according to the cell size. When assembling cells of different sizes, the ideal assembly spacing between the center lines of two adjacent sets of cells will change with the cell diameter. This results in the small cells having too large a spacing between them during the actual assembly process, causing the overall size of the assembled lithium battery to exceed the reasonable range, occupying too much space and affecting the overall layout and performance of the vehicle. In addition, this clamping and gripping method has high requirements for the initial distribution state of the battery cells. It requires the use of specialized battery cell distribution equipment, that is, to pre-distribute multiple battery cells at equal intervals according to specific requirements to assist the equipment in achieving clamping and gripping operations, thereby increasing the complexity and cost of using the equipment.

[0005] To address the aforementioned technical shortcomings, a solution is proposed that uses an adaptive, fully adhesive adsorption process for battery cells of different sizes to improve the gripping range and stability, while simultaneously adjusting the gripped battery cells at equal intervals to achieve the assembly of battery cells of different sizes with their corresponding brackets. Summary of the Invention

[0009] Preferably, the floating adsorption assembly includes a movable plate slidably mounted on a mounting base, with an elastic arc-shaped plate fixedly connected to the bottom of the movable plate, and an arc-shaped rubber plate with a hollow center installed on the concave side of the elastic arc-shaped plate.

[0010] Preferably, the mounting base is rotatably connected to a rotating roller that is slidably connected to multiple movable plates, and the annular outer wall of the rotating roller is provided with multiple guide grooves. Except for the middle guide groove which is vertically set, the others are inclined at different angles. The mounting base is equipped with a servo motor 2 that drives the rotating roller to rotate.

[0011] Preferably, the movable plate is internally slidably connected to a guide rod with a truncated cone-shaped top, and the guide groove has inclined surfaces on both sides.

[0012] Preferably, a plurality of limiting posts are fixedly connected to the concave side of the elastic arc plate, and an I-shaped groove penetrating its outer wall is opened inside the limiting post. An adsorption hole that abuts against the corresponding limiting post is opened on the arc rubber plate.

[0013] Preferably, the movable plate has a piston chamber inside, and a piston block that is fixedly connected to the guide rod is slidably connected inside the piston chamber. A connecting groove is formed between the top of both sides of the piston chamber and the inside of the arc-shaped rubber plate. An air pipe that communicates with the inside of the arc-shaped rubber plate is installed on the elastic arc-shaped plate.

[0014] Preferably, the elastic arc plate has symmetrically hinged bending plates on both sides, and the bending plates are hinged to the movable plate with support rods. An elastic plate with multiple suction cups is fixedly connected to the bending plate.

[0015] Preferably, the cleaning assembly includes a movable seat, a mounting groove that is slidably connected to the movable seat is provided through the bottom of the battery cell frame, an electric push rod that is fixedly connected to the movable seat is installed on the battery cell frame, a direct-drive electric roller and an auxiliary cylinder are rotatably connected to the top two sides of the movable seat respectively, and a cleaning brush is installed on the top of the movable seat between the direct-drive electric roller and the auxiliary cylinder.

Then, the gaps are filled by the supplementary assembly robot arm to ensure the full assembly of all cells and brackets. (3) When the battery cell of the present invention rolls between the top of the direct drive electric drum and the auxiliary drum, it uses the rising of the movable seat, combined with the toothed plate one, toothed plate two and gears, to achieve the upward movement of the partition stroke multiplied, and performs anti-rotation interference separation treatment on the battery cell and the battery cell on one side. Then, the direct drive electric drum and the auxiliary drum drive the battery cell to be cleaned to rotate, and the cleaning brush realizes the automatic cleaning of surface dust.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 and Figures 5-12 As shown, the problem that existing technologies cannot clamp and adjust the assembly spacing between cells of different sizes can be solved by the following solution; In this embodiment, the cell bracket assembly system for the lithium battery pack production line of electric motorcycle includes a conveyor 1, which conveys multiple cell brackets, and an assembly robot arm 11 and a replenishment robot arm 12 located on one side of the conveyor 1. The assembly robot arm 11 is equipped with a mounting base 13, and the mounting base 13 is provided with multiple floating adsorption components 2 that adaptively prevent the cells from falling off. The floating adsorption component 2 adsorbs and grasps battery cells of different sizes and adjusts the grasped battery cells at equal intervals to achieve the assembly of battery cells of different sizes with corresponding brackets. The replenishment robot arm 12 is equipped with grippers. The replenishment robot arm 12 and grippers are used to assemble the replenishment battery cell list. A battery cell frame 14 is set on one side of the assembly robot arm 11. Several battery cells are rolled and conveyed to the battery cell frame 14 by an external feeding mechanism. The battery cell frame 14 is used to place multiple conventional battery cells. A cleaning component 3 is set inside the battery cell frame 14 to separate and rotate battery cells with impurities on the surface.

[0022] A fixed frame 15 is mounted on the head shaft of the assembly robot arm 11, and a rotating plate 16 fixed to the mounting base 13 is rotatably connected to the fixed frame 15. A servo motor is mounted on the fixed frame 15 to drive the rotating plate 16 to deflect. The servo motor drives the rotating plate 16 to deflect the mounting base 13, so as to realize the forward and reverse assembly of multiple rows of battery cells on the bracket.

[0023] The floating adsorption assembly 2 includes a movable plate 21 that is slidably mounted on the mounting base 13. An elastic arc plate 22 is fixedly connected to the bottom of the movable plate 21, and an arc-shaped rubber plate 23 with a hollow structure in the middle is installed on the concave side of the elastic arc plate 22. Through the setting of the elastic arc plate 22 and the arc-shaped rubber plate 23, it can adapt to the deformation of the battery cell with different diameters, thereby achieving adaptive full fit for battery cells of different sizes, increasing the gripping area, and achieving stable gripping.

[0024] The mounting base 13 is rotatably connected to a rotating roller 17 that is slidably connected to multiple movable plates 21. Multiple guide grooves 18 are provided on the annular outer wall of the rotating roller 17. Except for the middle one which is vertical, the other guide grooves 18 are inclined at different angles. The mounting base 13 is equipped with a servo motor 2 that drives the rotating roller 17 to rotate. The servo motor 2 drives the rotating roller 17 to deflect. Combined with the guidance of the guide grooves 18 to guide the corresponding guide rods 24, the multiple movable plates 21 are driven to adjust the spacing between them at equal intervals, so as to realize the assembly of battery cells of different sizes with corresponding brackets.

[0025] The movable plate 21 is internally slidably connected to a guide rod 24 with a truncated cone top. The guide groove 18 has inclined surfaces on both sides. After the guide rod 24 slides down, the mounting base 13 moves down, causing the bottom sides of the elastic arc plate 22 to contact the battery cells. If there is a gap between two sets of battery cells (i.e., they do not contact each other), the movable plate 21 can achieve independent range-based floating offset in the length direction of the mounting base 13 through the truncated cone top of the guide rod 24 and the inclined surfaces on the sides of the guide groove 18. Multiple battery cells can be positioned on the concave side of the corresponding elastic arc plate 22 to achieve precise alignment and gripping of the battery cells. Then, the guide rod 24 slides upward, causing the top cone structure of the guide rod 24 to be fully inserted into the guide groove 18, limiting the floating offset of the movable plate 21, so as to make precise equal spacing adjustment later.

[0026] A number of limiting posts 25 are fixedly connected to the concave side of the elastic arc plate 22, and an I-shaped groove 26 penetrating its outer wall is opened inside the limiting post 25. An adsorption hole 27 that abuts against the corresponding limiting post 25 is opened on the arc rubber plate 23. The descent of the mounting base 13 causes the elastic arc plate 22 to undergo outward expansion deformation, which in turn causes the arc rubber plate 23 to expand outward simultaneously. This results in the concave side of the arc plate 22 fully and adaptively adhering to the outer wall of the battery cell. Combined with the multiple limiting posts 25 abutting against the battery cell, in the initial state of the elastic arc plate 22, the free end of the limiting post 25 is located inside the adsorption hole 27 and does not extend to the outside. That is, during the descent of the mounting base 13 under pressure, the elastic arc plate 22 first carries the arc rubber plate 23 to expand and deform, causing the arc concave surface of the arc rubber plate 23 to fully adhere to the arc surface of the battery cell. When the arc rubber plate 23 is squeezed and deformed in the thickness direction, the end of the limiting post 25 abuts against the battery cell to limit the squeezing and adhering of the inner cavity of the arc rubber plate 23. When the arc rubber plate 23 expands outward, it pulls the multiple adsorption holes 27 to deform. The adsorption hole 27 is partially separated from the limiting post 25 in a slit manner, and the air in the cavity of the multiple arc-shaped rubber plates 23 is extracted. Combined with the slit adsorption port generated by the deformation of the arc-shaped rubber plates 23, the battery cell is adsorbed and grasped. The size of the slit adsorption port is automatically adjusted according to the deformation of the elastic arc plate 22 caused by the size of the battery cell. That is, a large-diameter battery cell causes the deformation of the elastic arc plate 22 to increase, thereby increasing the size of the slit adsorption port. Conversely, a small-diameter battery cell corresponds to a small slit adsorption port, so as to ensure stable adsorption and grasping of battery cells of different sizes.

[0027] The movable plate 21 has a piston chamber 28 inside, and a piston block 29 fixed to the guide rod 24 is slidably connected inside the piston chamber 28. A connecting groove 210 is opened between the top of both sides of the piston chamber 28 and the inside of the arc-shaped rubber plate 23. An air pipe 211 communicating with the inside of the arc-shaped rubber plate 23 is installed on the elastic arc plate 22. It is synchronously connected to multiple air pipes 211 through an external negative pressure suction device. The external negative pressure suction device, combined with multiple air pipes 211, simultaneously extracts air from the cavities inside multiple arc-shaped rubber plates 23, thereby simultaneously adsorbing and grasping multiple battery cells. After the battery cells are adsorbed, during the movement of the mounting base 13 driven by the assembly robotic arm 11, the external negative pressure suction device works a second time, combined with the connecting groove 210 and piston chamber 28 that communicate with the cavity of the arc-shaped rubber plate 23, driving the piston block 29 to carry the guide rod 24 upward, so that the top cone structure of the guide rod 24 can be fully inserted into the guide groove 18 autonomously.

[0028] The two sides of the elastic arc plate 22 are symmetrically hinged with bending plates 212, and the bending plates 212 and the movable plate 21 are hinged with support rods 213. The bending plates 212 are fixedly connected with elastic plates 214 on which multiple suction cups are installed. When the mounting base 13 moves downward, the outward expansion deformation of the two sides of the elastic arc plate 22, combined with the bending plates 212 hinged on the two sides of the elastic arc plate 22 and the support rods 213, causes the two sets of elastic plates 214 to move relative to each other, carrying the suction cups to hold the battery cell, and the battery cell is grasped with the assistance of the suction cups. When a certain cell has a lot of dust on its surface and cannot be adsorbed and rise, the vacuum state inside the multiple arc-shaped rubber plates 23 disappears, and the remaining cells are temporarily restricted from falling by the adsorption of multiple suction cups on both sides, and the corresponding elastic arc-shaped plate 22 is restricted from resetting. The elastic arc-shaped plate 22 that the cell falls off deforms and resets, carrying the arc-shaped rubber plate 23 to reset, causing the inner wall of the adsorption hole 27 to fully fit the corresponding limiting post 25. Combined with the continuous operation of the external negative pressure suction device and the contact between the side wall of the adsorption hole 27 and the I-shaped groove 26, the adhesion force between the inner wall of the adsorption hole 27 and the limiting post 25 is enhanced, causing the vacuum environment inside the other multiple arc-shaped rubber plates 23 to be established again and quickly, so as to carry out stable gripping, conveying and assembly processing.

[0029] Example 2: Please refer to Figures 2-5 As shown, the following solutions can be used to address the problem of repeated handling of battery cells with a lot of dust on their surface, which leads to gaps in each row of cells during assembly and affects assembly efficiency. In this embodiment, the cleaning component 3 includes a movable seat 31. The bottom of the battery cell frame 14 is provided with a mounting groove that is slidably connected to the movable seat 31. An electric push rod that is fixedly connected to the movable seat 31 is installed on the battery cell frame 14. A direct-drive electric roller 32 and an auxiliary cylinder 33 are rotatably connected to the top sides of the movable seat 31, respectively. The battery cell with a lot of dust on its surface rolls to the top between the direct-drive electric roller 32 and the auxiliary cylinder 33. The direct-drive electric roller 32 and the auxiliary cylinder 33 drive the battery cell to rotate. A cleaning brush 34 is installed on the top of the movable seat 31 and between the direct-drive electric roller 32 and the auxiliary cylinder 33. When the battery cell rotates, it uses the cleaning brush 34 at its bottom to clean the surface dust. Then, the battery cell is height-adjusted by an electric push rod to ensure that the battery cell is at the same height as the other battery cells for gripping and assembly.

[0030] A partition 35 is slidably connected between one side of the movable seat 31 and the mounting groove. A toothed plate 36 is installed on the partition 35, and a toothed plate 37 is installed on the mounting groove. A gear 38 is rotatably connected to the movable seat 31 and meshes with the toothed plate 36 and the toothed plate 37. The electric push rod drives the movable seat 31 and carries the battery cell and gear 38 upward. During the upward movement of the gear 38, the meshing toothed plate 37 rotates, causing the toothed plate 36 to carry the partition 35 with a doubled upward movement, which prevents interference between the battery cell and the battery cell on one side, avoiding interference with the rotation of the battery cell. A triangular block is installed on the top of one side of the movable seat 31. The limit of the triangular block causes the battery cell to roll and is restricted between the top of the direct drive electric roller 32 and the auxiliary cylinder 33.

[0031] Example 3: Please refer to Figures 1-12 As shown, the present invention also proposes a method for using a cell bracket assembly system for a lithium battery pack production line for electric motorcycles, comprising the following steps: Step 1: Several battery cells are rolled and transported to the battery cell frame 14 by an external feeding mechanism. The conveyor table 1 transports multiple battery cell supports. The assembly robot arm 11 drives the mounting base 13 to move downward, so that the bottom sides of the elastic arc plate 22 contact the battery cells. If there is a gap between two sets of battery cells (i.e., they do not contact each other), the frustum structure at the top of the guide rod 24 and the inclined surface of the edge of the guide groove 18 enable the movable plate 21 to float and shift within a range in the length direction of the mounting base 13, so as to help multiple battery cells to be located on the concave side of the corresponding elastic arc plate 22. Step 2: As the mounting base 13 moves downward, the elastic arc plate 22 undergoes outward expansion deformation. Combined with the bent plates 212 hinged on both sides of the elastic arc plate 22 and the support rod 213, the two sets of elastic plates 214 move relative to each other, carrying the suction cup to hold the battery cell. The suction cup assists in grasping the battery cell. Step 3: When the elastic arc plate 22 undergoes outward expansion deformation, it causes the arc rubber plate 23 to expand outward simultaneously, causing its concave side to fully and adaptively adhere to the outer wall of the battery cell. It also abuts against the battery cell through multiple limiting posts 25 to limit the squeezing and adhesion of the inner cavity of the arc rubber plate 23. When the arc rubber plate 23 expands outward, it pulls multiple adsorption holes 27 to deform, causing the partial sidewall of the adsorption hole 27 to separate from the limiting post 25 in a slit manner. Through the external negative pressure air suction device and multiple air pipes 211, the air in the inner cavity of multiple arc rubber plates 23 is extracted synchronously, thereby synchronously adsorbing and grabbing multiple battery cells. Step 4: After the battery cells are adsorbed, as the assembly robot arm 11 moves the mounting base 13, the external negative pressure suction device continues to work. Combined with the connecting groove 210 and piston chamber 28 that communicate with the cavity of the arc-shaped rubber plate 23, the piston block 29 carries the guide rod 24 upward, causing the top cone structure of the guide rod 24 to be fully inserted into the guide groove 18, limiting the floating offset of the movable plate 21. The servo motor 2 drives the rotating roller 17 to deflect. Combined with the guidance of the guide groove 18 on the guide rod 24, the distance between multiple movable plates 21 is adjusted equidistantly. The servo motor 1 drives the rotating plate 16 to deflect, realizing the forward and reverse assembly of multiple rows of battery cells on the bracket. Step 5: During the process of the assembly robot arm 11 driving the mounting base 13 to rise away from the cell frame 14, when a cell surface contains a lot of dust, causing the two-stage adsorption to be weak and fall off and unable to rise, the vacuum state inside the multiple arc-shaped rubber plates 23 disappears. The remaining cells are temporarily restricted from falling off by the adsorption of multiple suction cups on both sides. Under the deformation and reset of the elastic arc plate 22, the arc-shaped rubber plate 23 is reset, causing the inner wall of the adsorption hole 27 to fully fit the corresponding limiting post 25. Combined with the contact between the side wall of the adsorption hole 27 and the I-shaped groove 26, the adhesion force between the inner wall of the adsorption hole 27 and the limiting post 25 is enhanced, causing the vacuum environment inside the remaining multiple arc-shaped rubber plates 23 to be re-established for stable gripping, conveying and assembly. After assembly, air is injected into the arc-shaped rubber plate 23 to loosen the clamp. The missing cells on the bracket are reassembled by the supplementary assembly robot arm 12 combined with the gripper. Step Six: The battery cell with a lot of dust on its surface rolls to the top of the movable seat 31. With the help of the triangular block, it rolls between the top of the direct-drive electric roller 32 and the auxiliary cylinder 33. The electric push rod drives the movable seat 31 and carries the battery cell and gear 38 upward. During the upward movement of the gear 38, the meshing toothed plate 37 rotates, causing the toothed plate 36 to carry the partition 35 with a doubled upward movement, which prevents interference between the battery cell and the battery cell on the other side. Then, the direct-drive electric roller 32 and the auxiliary cylinder 33 drive the battery cell to rotate. During the rotation, the cleaning brush 34 at its bottom cleans the surface dust. Finally, the electric push rod controls the height adjustment of the battery cell to ensure that the battery cell is at the same height as the other battery cells for gripping and assembly.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
