DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The embodiments of the cylindrical lithium battery cap packaging device and the processing method thereof are as follows:

[0050] Example 1: Please refer to Figure 1-Figure 14 A cylindrical lithium battery cap packaging device includes a packaging table 1 and a turntable 2. The turntable 2 is located at the bottom of the packaging table 1 and is provided with an annular cavity. An inner gear ring 21 is installed in the annular cavity. A motor is installed at the bottom of the packaging table 1. A gear member meshing with the inner gear ring 21 is installed at the output shaft end of the motor. The motor drives the turntable 2 to rotate intermittently. A plurality of cavities are arranged inside the turntable 2, and a placement ring 3 is fixedly arranged above the cavity.

[0051] Among them, multiple mounting tables can be extended on the side of the packaging table 1, and the mounting tables are used to install processing modules. The processing module includes a manipulator for placing the lithium battery in the placement ring 3 and a placement module for placing the cap in the lithium battery. If the cap is encapsulated in the lithium battery by laser welding, the processing module also includes a laser welding module. If the cap is encapsulated in the lithium battery by pressing, the processing module also includes a pressing module. In addition, the processing module also includes a CCD visual inspection module for detecting the lithium battery cap packaging. If the stability of the lithium battery cap packaging needs to be tested by tension, the processing module also includes a tension detection module. Secondly, the processing module also includes a taking module for taking away the lithium battery after the cap is packaged. The above processing modules are all existing processing technologies. If the mounting table is not set, the processing module can also be independently set at the corresponding position outside the packaging table 1.

[0052] A rotatable drum 4 is installed inside the cavity, and there is friction resistance between the drum 4 and the cavity. A plurality of clips 51 are distributed circumferentially inside the drum 4, and the cylindrical lithium battery can be clamped and fixed in the drum 4 by means of the clips 51. A lifting cylinder 9 is provided at the bottom of the drum 4, and a support plate 91 is installed inside the lifting cylinder 9 for sliding up and down. A buffer spring is provided between the lower surface of the support plate 91 and the bottom surface of the lifting cylinder 9. When the cylindrical lithium battery is placed in the placement ring 3, its bottom is supported by the support plate 91. If the lithium battery is capped by pressing, the lifting cylinder 9 is used for pressing and buffering. At the same time, after the lithium battery is capped by pressing and sealing, the lifting cylinder 9 is used to lift the lithium battery upward to avoid the lithium battery being stuck inside the drum 4, and to facilitate subsequent inspection and removal operations of the lithium battery.

[0053] A toothed disc 6 is rotatably installed in the cavity, and the inner and outer ring surfaces of the toothed disc 6 are both annular tooth surfaces. The rotation of the toothed disc 6 is utilized to provide a holding force for the clip 51 to clamp and fix the cylindrical lithium battery, to provide a driving force for the rotating drum 4 to drive the cylindrical lithium battery to rotate, and to provide a supporting force for the support plate 91 to support and lift the cylindrical lithium battery.

[0054] When capping cylindrical lithium batteries, different processing steps may require different forces to assist the lithium batteries inside the drum 4 to complete the corresponding processing. For example, when placing the lithium battery in the placement ring 3, only the support plate 91 is needed to support the lithium battery. Next, when placing the cap into the lithium battery, in order to improve the placement accuracy, the lithium battery is clamped by the clip 51 to prevent the lithium battery from shaking. If laser welding is used, the lithium battery is clamped by the clip 51, and the lithium battery cap can be rotationally welded by driving the drum 4 to rotate. If the cap is packaged by pressing, the support plate 91 is used to press and buffer the lithium battery, and after the pressing and packaging is completed, the support plate 91 is used to lift the lithium battery upward. Among them, when the cap is packaged by pressing, if it is necessary to add glue to the lithium battery before the cap is placed, the lithium battery can be clamped by the clip 51, and the lithium battery can be rotationally glued by driving the drum 4 to rotate.

[0055] When using CCD visual inspection to inspect the cap package of the lithium battery, the clamp 51 can be used to clamp the lithium battery to prevent the lithium battery from shaking, so as to improve the inspection accuracy; if it is necessary to test the tensile force of the cap package of the lithium battery, the clamp 51 is used to clamp the lithium battery so as to perform a tensile test on the cap packaging effect of the lithium battery.

[0056] The combined design of the placement ring 3, rotating cylinder 4, clip 51, lifting cylinder 9 and support plate 91 can provide corresponding forces for each process in the cap packaging process of the cylindrical lithium battery to complete the processing of the corresponding process. The design can be achieved by providing the same driving parts and has good versatility. At the same time, if it is necessary to add a processing step in the cylindrical lithium battery cap packaging process, the processing module corresponding to the processing step can be directly arranged in the corresponding process without redesigning the placement ring 3 on the surface of the turntable 2 and the structure inside the cavity.

[0057] On the basis of the above, a plurality of U-shaped adjusting slide bars 5 are radially slidably installed inside the rotating drum 4, and a clip 51 is fixed to the inner end of the adjusting slide bar 5; a tooth surface is provided inside the adjusting slide bar 5, and an adjusting gear 52 is meshed on the side of the tooth surface. The adjusting gear 52 is rotatably installed inside the rotating drum 4, and a gear 521 is coaxially arranged above the adjusting gear 52. The diameter of the gear 521 is larger than the diameter of the adjusting gear 52, and is used to reduce the linear speed of the adjusting gear 52, and at the same time facilitates reducing the matching size of the adjusting gear 52 and the adjusting slide bar 5, and the gear 521 is meshed with the inner tooth surface of the toothed disc 6.

[0058] Specifically, when the toothed disc 6 rotates, it meshes with the gear 1 521, driving the adjusting gear 52 to rotate. The adjusting gear 52 meshes with the inner tooth surface of the adjusting slide bar 5, driving the adjusting slide bar 5 to move radially. The adjusting slide bar 5 drives the clip 51 to move together, and the clip 51 is used to clamp the lithium battery inside the ring 3.

[0059] On the basis of the above, the inner wall of the cavity is provided with a plurality of circular holes, and the inner wall of the drum 4 is provided with a plurality of limiting holes 41, which can overlap with the circular holes on the inner wall of the cavity in the radial direction.

[0060] A push rod 53 is fixedly provided at one end of the adjusting slide rod 5 away from the clamping piece 51, and the push rod 53 corresponds to the corresponding limiting hole 41. A guide groove 411 with an arc transition is horizontally provided on one side of the circular hole of the inner wall of the cavity.

[0061] Specifically, when the adjusting slide bar 5 moves in the direction of the clip 51, the clip 51 clamps the lithium battery. At this time, the push rod 53 is in a separated state from the circular hole. When the adjusting slide bar 5 cannot continue to move radially, the rotation of the toothed disc 6 will enable the rotating drum 4 to overcome the friction resistance between it and the cavity, thereby driving the rotating drum 4 to move together. The rotating drum 4 drives the lithium battery placed inside the ring 3 to rotate together through the clip 51. The guide groove 411 is set on one side of the circular hole along the rotation direction of the above-mentioned rotating drum 4. The design of the guide groove 411 can facilitate the push rod 53 to return to the circular hole by rotating the toothed disc 6 in the opposite direction.

[0062] On the basis of the above, a plurality of cylinders 7 corresponding to the circular holes are distributed circumferentially on the outer side of the cavity, a piston rod 71 is sealingly and slidably installed inside the cylinder 7, a reset spring is provided between the piston rod 71 and the cylinder 7 for resetting the piston rod 71, the rod body of the piston rod 71 extends into the corresponding circular hole, and when the push rod 53 cooperates with the circular hole, it can push the piston rod 71 to move.

[0063] A pneumatic cylinder 10 is fixedly installed inside the lifting cylinder 9, and a sealing plate 101 is sealed and slidably installed up and down inside the pneumatic cylinder 10. A piston rod 102 is fixedly installed on the upper surface of the sealing plate 101. The upper end of the piston rod 102 extends to the outside of the pneumatic cylinder 10 and is fixedly connected to the lower surface of the support plate 91. A partition 103 is fixedly installed inside the pneumatic cylinder 10. The partition 103 is located below the sealing plate 101. A one-way valve 1031 is provided on the surface of the partition 103, and a through hole 1032 is opened. The gas flow direction of the one-way valve 1031 is from top to bottom, and the aperture of the through hole 1032 is smaller than the effective flow aperture of the one-way valve 1031.

[0064] Furthermore, an airbag 8 is provided between the cylinder 7 and the air pressure cylinder 10, the space on the side of the piston rod 71 inside the cylinder 7 away from the circular hole is connected to the airbag 8 through a pipe, and the airbag 8 is connected to the space below the partition 103 inside the air pressure cylinder 10 through a pipe.

[0065] Specifically, when the cylindrical lithium battery is pressed and capped, the support plate 91 is pressed and moved downwardly for buffering. The buffer spring and the gas under the sealing plate 101 inside the air pressure cylinder 10 are used to buffer and support the support plate 91. When the sealing plate 101 moves downward, part of the gas will be squeezed into the airbag 8. At this time, the rotation of the toothed disc 6 is used to move the adjusting slide rod 5 toward the direction of the circular hole, and the push rod 53 pushes the piston rod 71 to move. The piston rod 71 squeezes the gas inside the cylinder 7 to flow into the airbag 8, and the gas in the airbag 8 increases. When the cap is pressed and capped, After the packaging is completed, the compression force on the upper surface of the lithium battery disappears. At this time, the gas in the airbag 8 enters the space below the partition 103 and enters the space above the partition 103 through the through hole 1032, so that the sealing plate 101 and the support plate 91 are slowly reset and lifted, which can not only realize the lifting of the lithium battery, but also prevent the lithium battery from being bounced when lifted. After that, the push rod 53 and the piston rod 71 are reset, and the gas in the air pressure cylinder 10 is quickly reset through the one-way valve 1031 and the through hole 1032, so as to realize the rapid reset of the support plate 91 after lifting.

[0066] On the basis of the above, a T-shaped support plate 11 is arranged inside the turntable 2 , the lower end of the support plate 11 is fixedly connected to the packaging stage 1 , and the upper surface of the support plate 11 is located on the inner side of the turntable 2 .

[0067] A plurality of turntables 13 are arranged on the upper surface of the support plate 11. The turntables 13 correspond to the processing procedures that require clamping, rotation or lifting during the lithium battery cap packaging process. A driving gear set 131 is arranged on the surface of the turntable 13 for rotation. The driving gear set 131 consists of two meshing gears, one of which is driven to rotate by a motor module installed on the surface of the turntable 13. A transmission gear 61 is meshedly installed on the side of the gear plate 6. When the turntable 2 drives the placement ring 3 to rotate to a position corresponding to the turntable 13, the gear member in the driving gear set 131 can mesh with the corresponding transmission gear 61.

[0068] Specifically: when the turntable 2 drives the cylindrical lithium battery in the placement ring 3 to move to the position corresponding to the turntable 13, if a clamping, rotating or lifting force is required for the lithium battery at this work station, the motor module on the surface of the turntable 13 is started to drive the gears in the gear set 131 to rotate, and the toothed disc 6 is driven to rotate by engaging with the transmission gear 61, and the rotation of the toothed disc 6 is used to provide a corresponding force for the lithium battery.

[0069] On the basis of the above, the turntable 13 is slidably set on the surface of the support plate 11, the sliding track of the turntable 13 is circular, and an adjustment plate 12 is rotatably installed inside the support plate 11. A motor device for driving the adjustment plate 12 to rotate is provided inside the support plate 11, and the position of the turntable 13 is adjusted by the rotation of the adjustment plate 12.

[0070] Specifically, by designing the turntable 13 to be adjustable, when changing the processing procedure of the lithium battery cap packaging or adjusting the position of the processing procedure, the position of the turntable 13 can be directly adjusted accordingly, which is beneficial to improving the overall adjustability and environmental adaptability of the cylindrical lithium battery cap packaging equipment.

[0071] On the basis of the above, a connecting rod 132 is radially slidably arranged inside the turntable 13, and a plurality of connecting blocks 121 are circumferentially arranged on the side surface of the adjusting disk 12. The surface of the connecting block 121 is provided with connecting holes, and when the connecting rod 132 slides radially, it can cooperate with the connecting hole.

[0072] On the basis of the above, a boss 111 is fixedly provided on the upper surface of the support plate 11, the adjustment plate 12 is located above the boss 111, and a plurality of limiting holes 112 are circumferentially opened on the side surface of the boss 111. A limiting column 133 is radially slidably installed inside the turntable 13. When the connecting rod 132 and the connecting hole are in a separated state, the limiting column 133 is in a mating state with one of the limiting holes 112.

[0073] The connecting rod 132 and the limiting column 133 have gear rods 151 on their opposing surfaces. An intermediate gear 15 is rotatably installed inside the turntable 13. The intermediate gear 15 is meshed with the gear rods 151 on the surfaces of the connecting rod 132 and the limiting column 133 at the same time. An electromagnetic telescopic rod 14 is installed inside the turntable 13 to drive the connecting rod 132 to move radially.

[0074] Specifically, the electromagnetic telescopic rod 14 is used to drive the connecting rod 132 to move radially. When the connecting rod 132 moves toward the connecting hole, the limiting column 133 moves away from the second limiting hole 112 under the cooperation of the gear rod 151 and the intermediate gear 15. When the connecting rod 132 cooperates with the corresponding connecting hole, the limiting column 133 and the corresponding second limiting hole 112 are in a separated state. At this time, the turntable 13 can be driven to rotate by the rotation of the adjusting disk 12. When the turntable 13 moves to the set position, the driving of the adjusting disk 12 to rotate is stopped. At the same time, the electromagnetic telescopic rod 14 is used to drive the connecting rod 132 to separate from the corresponding connecting hole. Correspondingly, the limiting column 133 will cooperate with the corresponding second limiting hole 112 to limit the turntable 13.
