Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to a packaging device for manufacturing cylindrical batteries. Background Technology

[0002] In the battery manufacturing process, the battery cap is a key component of the battery. Sealing the edge of the battery cap with a sealing ring is one of the important processes to ensure the safety of battery use. Cylindrical batteries are mainly composed of cells and casings. After the cells and casings are manufactured separately, the cells need to be installed into the casings. In order to improve the battery processing speed, automated equipment is used for the cell installation process.

[0003] For example, patent application publication number CN112670527A discloses a battery cap packaging machine, including a frame, a feeding track, a packaging component, a feeding component, a packaging mold, and a pushing component. In use, the feeding component pushes the battery cap from the feeding track into the packaging component to avoid feeding jams. Then, the pushing component pushes the battery cap to fill the packaging slot with accurate positioning. After the lower mold pushes the battery cap into the upper mold for packaging, it retracts. The upper mold top core presses down on the battery cap, and the packaging action moves smoothly up and down.

[0004] Taking the aforementioned battery cap packaging machine as an example, the core design goal of the battery cap packaging machine is to seal the edge of the sealing ring of a single component of the battery cap, realizing only the independent process cycle of "feeding → loading → packaging → unloading". However, processes such as cell insertion and multi-component assembly are still carried out independently, which means that cylindrical battery production requires additional cell insertion equipment and battery cap assembly equipment. The process is fragmented, with high time costs and low economic benefits. Summary of the Invention

[0026] Specifically, such as Figure 3 A rubber pad 7 is provided on the side of the guide frame 54 away from the conveying equipment 3 4. The diameter of the rubber pad 7 is smaller than the diameter of the battery core 5. A pneumatic cylinder 6 is fixedly installed on the top of the workbench 1.

A second separator 13 is fixedly installed at the top of the rack 12. The top of the second separator 13 passes through the workbench 1 and extends to one side of the guide frame 54. The second separator 13 and the rubber pad 7 work together to block both sides of the guide frame 54, ensuring that the battery core 5 conveyed by the first conveyor 2 moves to the preset position.

[0028] A guide frame 14 is fixedly installed at the bottom of the workbench 1. The guide frame 14 passes through the partition frame 2 13 and guides the partition frame 2 13 so that the partition frame 2 13 can only move up and down. A pneumatic cylinder 2 15 is fixedly installed inside the guide frame 14. The piston end of the pneumatic cylinder 2 15 is fixedly connected to the partition frame 2 13. By controlling the operation of the pneumatic cylinder 2 15, the up and down movement of the partition frame 2 13 can be controlled.

[0029] Specifically, such as Figure 3 , Figure 4 , Figure 8 , Figure 12 , Figure 13 and Figure 14 In the top material structure, the sliding groove 16 is opened on the top of the workbench 1.

[0030] A pneumatic cylinder 3 18 is fixedly installed inside the support frame 20. A support frame 1 17 is fixedly installed on the piston end of the pneumatic cylinder 3 18. Multiple telescopic rods 2 19 are fixedly installed on the top of the support frame 20. The piston ends of the telescopic rods 2 19 are fixedly connected to the support frame 1 17. Under the limitation of the multiple telescopic rods 2 19, the support frame 1 17 can only move up and down. By controlling the operation of the pneumatic cylinder 3 18, the up and down position of the support frame 1 17 can be controlled. There is a liquid storage tank 22 on the side of the support frame 20 near the conveying equipment 1 2. Multiple inclined rods are fixedly installed between the liquid storage tank 22 and the support frame 20. The liquid storage tank 22 and the support frame 20 move synchronously. Heaters 23 are fixedly installed on both sides inside the liquid storage tank 22. The heaters 23 heat the inside of the liquid storage tank 22 to keep the liquid inside the liquid storage tank 22 at a certain temperature to prevent it from solidifying.

[0031] A brush 24 is installed inside the liquid storage tank 22. A conduit 25 and a guide frame 26 are fixedly installed on both sides of the bottom of the brush 24.

The piston end of the pneumatic cylinder 5 28 is fixedly connected to the support frame 3 27. By controlling the operation of the pneumatic cylinder 5 28, the up and down positions of the support frame 3 27 and the brush 24 can be controlled. A one-way valve 30 is fixedly installed at the bottom of the conduit 25. Under the one-way conduction characteristic of the one-way valve 30, the glue inside the liquid storage tank 22 cannot be discharged through the one-way valve 30. A drain groove 29 is opened on the outside of the conduit 25. The drain groove 29, which is set inside the liquid storage tank 22, connects the conduit 25 and the inside of the liquid storage tank 22. The glue can be replenished into the liquid storage tank 22 through the glue supply system connected to the one-way valve 30.

[0032] Specifically, such as Figure 8 , Figure 9 , Figure 10 and Figure 11 In the rotary drive assembly, gear 2 39 is rotatably connected to support frame 5 38. Gear 3 43 meshes with gear 2 39 on its outer side. Support frame 6 40 is fixedly connected between the housing of drive motor 41 and support frame 5 38. Drive motor 41 cannot rotate relative to support frame 5 38. Drive shaft 42 is fixedly installed at the output end of drive motor 41. Gear 3 43 is fixedly installed on the outer side of drive shaft 42, thus controlling the operation of drive motor 41. Under the transmission of drive shaft 42 and gear 3 43, gear 2 39 rotates on one side of support frame 5 38. Multiple spring telescopic rods 46 and pneumatic telescopic rods 45 fixedly installed on one side of gear 2 39 rotate. The piston ends of spring telescopic rods 46 and pneumatic telescopic rods 45 are fixedly connected to negative pressure suction cup 47. Negative pressure suction cup 47 rotates synchronously with gear 2 39. The battery cover 48 fixed by negative pressure suction cup 47 rotates, adjusting the position of battery cover 48.

[0033] A brake 44 is provided on the outside of the drive shaft 42. The brake 44 is fixedly connected to the support frame 38. After the drive motor 41 finishes working, the brake 44 is controlled to brake and limit the drive shaft 42, ensuring the stability of the position control of the gear 39 and the negative pressure suction cup 47.

[0034] In the position control assembly, the forward and reverse motor 32 is fixedly installed on the top of the worktable 1. An electric push rod 57 is installed on the outside of the lead screw 33 fixedly installed at the output end of the forward and reverse motor 32 via a nut pair. A support frame 35 is fixedly installed on the piston end of the electric push rod 57. By controlling the operation of the electric push rod 57, the up and down position of the support frame 35 can be controlled. Two guide frames 34 passing through the outer shell of the electric push rod 57 are fixedly installed on the top of the worktable 1. Under the limiting guidance of the two guide frames 34, the support frame 35 can only move left and right.

[0035] A pneumatic cylinder 6 36 and two telescopic rods 3 37 are fixedly installed on one side of the support frame 4 35. The piston ends of the pneumatic cylinder 6 36 and the two telescopic rods 3 37 are fixedly connected to the support frame 5 38. Under the action of the pneumatic cylinder 6 36 and the two telescopic rods 3 37, the support frame 5 38 can only move back and forth. By controlling the operation of the pneumatic cylinder 6 36, the front and back positions of the support frame 5 38, gear 2 39 and negative pressure suction cup 47 can be controlled.

[0036] An air pump 52 is fixedly installed on the other side of the support frame 435. A solenoid valve 53 is fixedly installed at the air inlet end of the air pump 52. One end of the flexible hose 51 rotatably installed at the air outlet end of the air pump 52 is rotatably connected to the negative pressure suction cup 47. The flexible hose 51, which can extend and retract to a certain length, will not affect the movement and rotation of the negative pressure suction cup 47. It controls the operation of the air pump 52. The air pump 52 controls the air pressure inside the negative pressure suction cup 47 through the flexible hose 51, so that the negative pressure suction cup 47 adsorbs and fixes the battery cover 48.

[0037] The battery packaging equipment consists of a workbench 1, conveyor equipment one 2, conveyor equipment two 3, conveyor equipment three 4, battery cell 5, robotic arm 31, battery cover 48, guide rack 54, workpiece displacement control structure, battery cover feeding structure, and top material structure. The working steps of the battery packaging equipment are as follows: Step 1: Control the operation of conveyor 2. One end of the working conveyor 2 is fixedly installed with a guide frame 54. The two sides of the guide frame 54 are blocked by the partition frame 13 and the rubber pad 7. The battery core 5 conveyed by the conveyor 2 rolls inside the guide frame 54. The battery core 5 cannot leave the preset movement trajectory. When a battery core 5 moves into the inside of the guide frame 54, the conveyor 2 stops working.

[0038] Step 2: Control the operation of pneumatic cylinder 2 15 to drive the separator 2 13 downward, so that the side of the battery core 5 near the battery cover feeding structure of the worktable 1 is unobstructed; during the downward movement of separator 2 13, the rack 12 fixedly installed on separator 2 13 moves downward, and rack 12 drives gear 11 fixedly installed on the outside of the input end of screw jack 10 to rotate, screw jack 10 extends, gear 11 pushes separator 8 upward, and most of separator 8 enters the inside of guide frame 54. Separator 8 separates the battery core 5 located on the side of pneumatic cylinder 6 from the other battery core 5 inside the conveying equipment 2, so as to avoid the other battery core 5 affecting the operation of pneumatic cylinder 6 and ensure that pneumatic cylinder 6 stably pushes the battery core 5.

[0039] Step 3: After the second pneumatic cylinder 15 stops working, the first pneumatic cylinder 6 pushes the battery cell 5 on one side forward through the rubber pad 7. When the middle position of the battery cell 5 moves to the top of the support frame 17, the fourth pneumatic cylinder 21 is controlled to work to drive the second support frame 20 forward. The second support frame 20 drives the first support frame 17 forward. The first support frame 17 moves forward synchronously with the battery cell 5. The first support frame 17 supports the bottom of the battery cell 5 to prevent the battery cell 5 from tilting and rolling, and to ensure the positioning accuracy of the battery cell 5. Through the cooperation of the first pneumatic cylinder 6, the rubber pad 7, the separator 8, the screw jack 10, the second pneumatic cylinder 15, and the fourth pneumatic cylinder 21, the multiple battery cells 5 conveyed by the conveying equipment 2 are limited, and the battery cells 5 that have moved to the processing position inside the guide frame 54 are conveyed and positioned.

[0040] During the conveying and positioning process, the forward and reverse motor 32 rotates forward. The forward and reverse motor 32 drives the support frame 4 35 to move left via the lead screw 33. The support frame 4 35, support frame 5 38, gear 2 39, and negative pressure suction cup 47 move left. When the negative pressure suction cup 47 aligns with the pre-drilled slot 55 of the conveying device 3 4, the forward and reverse motor 32 stops working. Then, the pneumatic cylinder 6 36 operates, pushing the support frame 5 38 backward. The support frame 5 38, gear 2 39, and negative pressure suction cup 47 move backward. When the negative pressure suction cup 47 abuts against the battery cover 48 through the pre-drilled slot 55, with the operation of the pneumatic cylinder 6 36, the negative pressure suction cup 47... As the stress between the 7 and the battery cover 48 increases, the sealing between the negative pressure suction cup 47 and the battery cover 48 increases. At this time, the pneumatic telescopic rod 45 retracts, increasing the internal air pressure. The air pressure sensor 56 monitors the internal air pressure value of the pneumatic telescopic rod 45 in real time and feeds it back to the human-machine interface device. When the air pressure value fed back by the air pressure sensor 56 reaches the preset value, the human-machine interface device controls the pneumatic cylinder 36 to stop working and controls the air pump 52 to work to draw air from the inside of the negative pressure suction cup 47 through the hose 51. The negative pressure suction cup 47 and the battery cover 48 enter a negative pressure state, and the negative pressure suction cup 47 adsorbs and fixes the battery cover 48.

[0041] Step 4: After the vacuum pump 52 has been working for a period of time, the vacuum pump 52 stops working, the solenoid valve 53 closes, and the negative pressure suction cup 47 maintains a negative pressure state with the battery cover 48. Then, the electric push rod 57 is controlled to push the support frame 35 upward, and the negative pressure suction cup 47 drives the battery cover 48 upward, leaving the inside of the conveying device 34. Then, the forward and reverse motor 32 reverses its operation, and the forward and reverse motor 32 drives the support frame 35 to move to the right through the lead screw 33. The negative pressure suction cup 47 moves to the right. When the support frame 35 is reset, the electric push rod 57 retracts and drives the negative pressure suction cup 47 to move downward and reset. The negative pressure suction cup 47 drives the battery cover 48 to move downward and onto the movement path of the battery core 5, completing the positioning of the battery cover 48.

[0042] Step 5: After the working time of pneumatic cylinder 6 is reached, the two electrode posts on the battery cell 5 press against the battery cover 48, the pneumatic telescopic rod 45 retracts, and after the air pressure value detected by the air pressure sensor 56 reaches the preset value, the human-machine interface device controls pneumatic cylinder 6 to stop working; then, the drive motor 41 is controlled to work at low power, the drive motor 41 drives the transmission shaft 42 and the gear 3 43 fixed on the outside of the transmission shaft 42 to rotate, the gear 3 43 drives the meshing gear 2 39 to rotate synchronously, the gear 2 39 rotates slowly, and the negative pressure suction cup 47 drives... The battery cover 48 rotates slowly. Since the positions of the two electrode posts on the battery core 5 and the two electrode post holes 49 on the battery cover 48 are preset, when the two electrode posts are aligned with the two electrode post holes 49, the rebounding spring telescopic rod 46 and the pneumatic telescopic rod 45 push the negative pressure suction cup 47 to move. The battery cover 48 is then fitted onto the outside of the electrode posts of the battery core 5, and the positioning and installation of the battery cover 48 and the battery core 5 is completed. At this time, the pressure value detected by the pneumatic pressure sensor 56 is restored, and the human-machine interface device controls the pneumatic cylinder 6 to reset.

[0043] If, during the operation of the pneumatic cylinder 6, the battery core 5 is pushed towards the battery cover 48, and the electrode post on the battery core 5 directly penetrates the electrode post hole 49, and after the working time of the pneumatic cylinder 6 is reached, the battery cover 48 does not shift, the pneumatic telescopic rod 45 does not retract, and the air pressure value detected by the air pressure sensor 56 cannot reach the preset value, then the positioning and installation work of the battery cover 48 and the battery core 5 is completed.

[0044] Step Six: After the battery cover 48 and battery core 5 are positioned and installed, the pneumatic cylinder 6 retracts and drives the rubber pad 7 to reset. The robotic arm 31 clamps and fixes a battery casing from inside the conveying device 2 3. As the battery casing is conveyed by the conveying device 2 3 according to the preset trajectory, the robotic arm 31 moves the battery casing to the end of the battery core 5 away from the battery cover 48, with the opening of the battery casing facing the battery core 5.

[0045] Step 7: Control the operation of pneumatic cylinder 6 36 to push the battery cover 48 and battery core 5 into the battery casing. During this process, pneumatic cylinder 5 28 works multiple times to push brush 24 up and then down back into the reservoir 22. As the battery core 5 and battery cover 48 enter the battery casing, drive motor 41 drives gear 2 39, negative pressure suction cup 47, battery cover 48, and battery core 5 to rotate. Pneumatic cylinder 6 36 pauses its operation for a period of time multiple times during this process. The brush 24, which moves upward multiple times, creates multiple grooves 50 at multiple positions on the outside of battery core 5 and on the outside of battery cover 48. When the battery core 5 and battery cover 48 are inserted into the battery casing, the battery cover 48 and the battery casing are in an interference fit. The multiple grooves 50 ensure that some of the adhesive is always between the outer side of the battery cover 48 and the inner wall of the battery casing, so that the battery cover 48 and the battery casing are glued together and the battery core 5 is glued together. At the same time as the battery core 5 is inserted into the battery casing, the battery cover 48 and the electrode post end of the battery core 5 are positioned, and the battery cover 48 and the battery casing are sealed, which shortens the time cost of the battery core 5 being inserted into the casing. Overcoming the limitations of traditional battery packaging equipment that can only complete a single battery cap packaging process, this equipment integrates core processes such as battery core 5 conveying and positioning, precise gripping of battery cap 48, alignment of battery core 5 with electrode post holes 49 on battery cap 48, battery core 5 insertion into the casing, and adhesive sealing of the casing and battery core 5, and battery core 5 and battery cap 48, into a single machine. This eliminates the intermediate steps of core transfer and multiple loading and unloading in traditional production, avoids waiting time during process transitions, significantly shortens the production cycle of a single battery, eliminates the need for additional cell insertion equipment or battery cap assembly equipment, reduces the investment in purchasing multiple machines, saves factory space required for multiple machine layouts, reduces the complexity of production line layout, and ensures the economic benefits of the insertion equipment application.

[0046] Furthermore, during the movement of the battery core 5 and battery cover 48 into the battery casing, the battery core 5 partially enters the battery casing. After the battery cover 48 approaches the support frame 17, the pneumatic cylinder 3 18 operates to drive the support frame 17 downward, ensuring that the battery cover 48, whose outer diameter is slightly larger than that of the battery core 5, can move smoothly to meet the interference fit with the battery casing. This avoids friction between the battery cover 48 and the support frame 17 that supports the battery core 5, ensuring that the battery cover 48 effectively fits with the battery casing to encapsulate the battery core 5. The workpiece displacement control structure, through the coordinated action of the separator 1 8, separator 2 13, and other parts, separates, limits, and pushes the battery core 5 one by one, ensuring the positional stability of the battery core 5 before entering the casing, and avoiding problems such as failure to enter the casing or damage to the casing caused by the tilting or displacement of the battery core 5.

[0047] Step 8: After the battery cover 48 is fully inserted into the battery casing, the internal air pressure of the pneumatic telescopic rod 45 reaches the preset value. The air pressure sensor 56 feeds back the internal air pressure value of the pneumatic telescopic rod 45 to the human-machine interface device. After the internal air pressure of the pneumatic telescopic rod 45 reaches the preset value, the human-machine interface device controls the solenoid valve 53 to open, the internal pressure of the negative pressure suction cup 47 is released, the fixing between the negative pressure suction cup 47 and the battery cover 48 is removed, the pneumatic telescopic rod 45 is controlled to drive the negative pressure suction cup 47 to reset, and the robotic arm 31 is controlled to transport the packaged battery casing, battery core 5 and battery cover 48 to the storage position and put them down. Finally, the robotic arm 31 resets, the pneumatic cylinders 21 and 18 work, the support frame 17 resets, the pneumatic cylinder 15 works to push the separator frame 13 to reset, the separator frame 8 moves down, and the next battery core 5 enters the guide frame 54.
