Description

Technical Field

[0001] This invention applies to the field of heat shrink tubing, and is named a heat shrink tubing kit for battery casings. Background Technology

[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion.

[0003] However, existing equipment mostly uses adhesive bonding for battery encapsulation, which makes the battery casing prone to falling off during production. Furthermore, the bottom and top of the encapsulated battery cannot be completely sealed, causing the encapsulation sleeve to wear easily. Using heat-shrinkable materials to encapsulate batteries not only provides strong wrapping but also has good practicality. Current technology mostly involves manually heating and shrinking hot water pipes, and the cutting and fitting of heat-shrinkable tubing requires multiple machines to complete separately, wasting time and resources.

[0004] Therefore, it is necessary to provide a device for packaging heat shrink tubing for batteries, which can efficiently package and heat shrink the batteries with heat shrink tubing and collect the finished products. Summary of the Invention

This efficiently realizes the heat shrink tubing for battery packing and heat shrinking, and completes the collection of the finished product, making it highly practical. Attached Figure Description

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] Please see Figure 1-8This invention provides a technical solution: a device for assembling heat shrink tubing for battery casings, comprising a base 1, a support plate 9, a support frame 35, and a conveying frame 51. A base plate 10 is fixedly installed above the support plate 9, a support seat 11 is provided above the base plate 10, and a fixing plate 12 is provided above the support seat 11. A first pushing device 65 is provided on the rear side of the fixing plate 12, and an upper roller 14 is connected to the pushing end of the first pushing device 65 by a bearing. A second pushing device 66 is provided on the rear side of the fixing plate 12, and a lower roller 67 is connected to the pushing end of the second pushing device 66 by a bearing. A first motor 16 is provided on the front side of the fixing plate 12, and a lower roller 67 is connected to the rear side of the fixing plate 12 by a bearing. The first gear 18 is connected to the rear bearing of the fixed plate 12, and the first gear 18 and the second gear 19 are meshed with each other. The output end of the first motor 16 is provided with a third gear 17, which is meshed with the first gear 18. A left push drum 15 is provided in front of the first gear 18, and a right push drum 20 is provided in front of the second gear 19. The inner side of the upper roller 14 holds the conveying pipe 13, which is located inside the left push drum 15 and the right push drum 20. The lower roller 67 is clamped and connected to the conveying pipe 13. The first push device 65 will drive the upper roller 14 to slide inward from the clamped position via the internal push rod. When the heat shrink tubing is fitted onto the upper end of the delivery tube 13 and slides downwards, the second pushing device 66 drives the lower roller 67 to slide inwards, clamping the delivery tube 13. Then, the first pushing device 65 drives the upper roller 14 to slide outwards via its internal pushing rod, causing the upper roller 14 to release the delivery tube 13. The worker pulls the heat shrink tubing downwards to the inside of the left pushing drum 15 and the right pushing drum 20. Then, the first motor 16 starts, driving the left pushing drum 15 to rotate clockwise and the right pushing drum 20 to rotate counterclockwise via the rear-meshing first gear 18 and second gear 19, thereby pulling the heat shrink tubing fitted onto the delivery tube 13 downwards. To achieve the conveying effect, since the lower roller 67 clamps the conveying tube 13, the heat shrink tubing will accumulate above the lower roller 67. After the left push drum 15 and the right push drum 20 rotate for a certain period of time, the length of the accumulated heat shrink tubing will be equal to the length of the battery 8. At this time, the left push drum 15 and the right push drum 20 stop rotating. Then, the first push device 65 drives the upper roller 14 to slide inward to clamp the conveying tube 13. The second push device 66 drives the lower roller 67 to release the conveying tube 13. Then, the lower roller 67 rotates in the same way as the left push drum 15 and the right push drum 20, and continues to convey the accumulated heat shrink tubing downward, thereby achieving the effect of quantitative conveying.

[0025] A second motor 21 is fixedly installed above the base plate 10. A fourth gear 23 is provided at the output end of the second motor 21. A connecting sleeve 22 is provided below the base plate 10. A fifth gear 24 is connected to the bearing below the connecting sleeve 22. The fourth gear 23 and the fifth gear 24 are meshed with each other. A support sleeve 25 is provided below the fifth gear 24. A third pushing device 26 is fixedly installed below the support sleeve 25. A cutting block 27 is fixedly installed at the pushing end of the third pushing device 26. A cutting blade 28 is fixedly installed on the inner side of the cutting block 27. A cutting groove 29 is provided below the conveying pipe 13. After the heat shrink tubing has been conveyed to the bottom by the lower roller 67 and successfully fitted onto the battery 8, the second motor 21 starts and drives the fifth gear 24 to rotate through the fourth gear 23, thereby causing the support sleeve 25 to rotate. Then, the third pushing device 26 pushes the cutting block 27 inward through the internal pushing end, so that the cutting blade 28 can be inserted into the cutting groove 29 and rotate with the support sleeve 25, thereby cutting off the heat shrink tubing above the battery 8, thus completing the heat shrink tubing fitting process of the battery 8.

[0026] A third motor 2 is fixedly installed above the base 1. A turntable 3 is fixedly installed at the output end of the third motor 2. A clamping frame 5 is fixedly installed above the turntable 3. A push rod 4 is slidably connected to the end of the clamping frame 5. A left clamping plate 6 is connected to the left bearing of the clamping frame 5, and a right clamping plate 7 is connected to the right bearing of the clamping frame 5. A battery 8 is located above the turntable 3. A fixing chamber 68 is located above the base 1. A hot air blower 30 is fixedly installed inside the fixing chamber 68. A [missing information - likely a device or component] is located below the hot air blower 30. A connecting pipe 31 is provided, below which is a rotating chamber 32. Above the fixed chamber 68 is a processing chamber 33. Heat dissipation holes 34 are provided on the outer side of the processing chamber 33. When the push rod 4 is pushed outwards, the protrusions on both sides of the push rod 4 will push open the left clamping plate 6 and the right clamping plate 7, causing the left clamping plate 6 to rotate clockwise and the right clamping plate 7 to rotate counterclockwise. This allows the left clamping plate 6 and the right clamping plate 7 to cooperate with the top of the push rod 4 to clamp the battery 8. When the battery 8 is placed on the turntable 3, it will be clamped for the first time, and then... When the heat shrink tubing slides down and covers the battery 8, it will release, and then the heat shrink tubing will be fully fitted. The left clamping plate 6 and the right clamping plate 7 will hold the heat shrink tubing and the battery 8 together for easy cutting. After the hot air blower 30 is started, it will blow out hot air, which will be transmitted to the rotating chamber 32 through the connecting pipe 31. When the rotating chamber 32 rotates, it will cool the hot air to a suitable temperature and deliver it to the processing chamber 33. The battery 8 will rotate into the processing chamber 33 through the turntable 3. The heat shrink tubing on the outside of the battery 8 will shrink due to the temperature inside the processing chamber 33, thus wrapping the battery 8. The turntable 3 is provided with a boss, so that there is a gap between the battery 8 and the turntable 3, so that the bottom of the heat shrink tubing can fit against the turntable 3 when it is fitted on the outside of the battery 8. When the heat shrink tubing shrinks inside the processing chamber 33, in addition to the outer side shrinking, the heat shrink tubing above and below the battery 8 will shrink together to wrap the battery 8, thereby improving the wrapping effect. Excess hot air will be discharged from the heat dissipation hole 34 to prevent the temperature inside the processing chamber 33 from being too high and damaging the battery 8, thereby achieving the effect of heat shrink wrapping.

[0027] A guide tube 36 is provided above the support frame 35, and a first cylinder 38 is provided above the support frame 35. A push plate 37 is fixedly installed at the output end of the first cylinder 38, and the push plate 37 is slidably connected to the guide tube 36. A support block 52 is provided on the outer side of the base 1, and a second cylinder 39 is slidably connected to the left side of the support block 52. A rack 40 is provided on the left side of the second cylinder 39, and the rack 40 is slidably connected to the push plate 37. A sixth gear 41 is connected to the upper bearing of the push plate 37, and the sixth gear 41 meshes with the rack 40. The connection is as follows: an extension rod 42 is installed above the sixth gear 41; a rotating rod 43 is installed above the extension rod 42; a first suction machine 44 is installed to the left of the rotating rod 43; a first suction head 45 is installed below the first suction machine 44; a second suction machine 46 is installed to the right of the rotating rod 43; a second suction head 47 is installed below the second suction machine 46; a raising platform 48 is installed at the front of the support frame 35; a conveyor belt 49 is installed above the raising platform 48; and a power unit 50 is installed on the outside of the conveyor belt 49. Cylinder 38 can drive push plate 37 to slide up and down on guide tube 36 via an internal air rod. When the processed battery 8 reaches the designated position, left clamp 6 and right clamp 7 release battery 8. First cylinder 38 drives push plate 37 to descend, thereby driving second suction machine 46 to descend via extension rod 42. At the same time, second suction machine 46 starts and sucks up battery 8 through second suction head 47. Then first cylinder 38 drives push plate 37 to rise, causing battery 8 to rise and detach from turntable 3. At this time, second cylinder 39 starts and drives push plate 37 to slide up and down on guide tube 36 via internal air rod. The pneumatic rod drives the rack 40 to slide to the right. The sixth gear 41, which meshes with the rack 40, starts to rotate due to the pull of the rack 40, thereby driving the extension rod 42 to rotate. This causes the second vacuum pump 46 and the first vacuum pump 44 to exchange positions. Then, the first cylinder 38 repeats the previous action to drive the push plate 37 to descend. The second vacuum pump 46 stops, and the battery 8 is detached and falls onto the conveyor belt 49 for transport. At the same time, the first vacuum pump 44 uses the first suction head 45 to pick up a new battery 8 again, thus completing the gripping and transport of the battery 8.

[0028] A fourth motor 53 is installed on the outer side of the conveyor frame 51. A rolling shaft 54 ​​is installed on the inner side of the fourth motor 53. A first sprocket 55 is installed on the outer side of the rolling shaft 54. A second sprocket 57 is installed on the inner side of the conveyor frame 51. The first sprocket 55 and the second sprocket 57 are connected to each other by a meshing chain 56. A telescopic fixing head 59 is installed on the inner side of the second sprocket 57. A winding drum 58 is installed on the inner side of the telescopic fixing head 59. A guide rail 60 is installed on the inner side of the conveyor frame 51. A sliding rod 62 is slidably connected above the guide rail 60. A fourth pushing device 61 is installed on the inner side of the conveyor frame 51. The pushing end of the fourth pushing device 61 is fixedly connected to the sliding rod 62. A groove 63 is installed on the inner side of the sliding rod 62. A rolling wheel group 64 is slidably connected on the inner side of the groove 63. The worker will wrap the heat shrink tubing with the rollers. The take-up drum 58 is delivered to a fixed position and then fixed by the telescopic fixing head 59. The fourth motor 53 is then started to drive the first sprocket 55 to rotate, which in turn drives the connected second sprocket 57 to rotate via the chain 56. This causes the take-up drum 58 to slowly unwind. The heat shrink tubing is then pulled to the inside of the roller assembly 64 and then onto the conveyor pipe 13. Because the position of the heat shrink tubing on the take-up drum 58 varies, it can easily become too loose, affecting subsequent processes. The fourth pushing device 61 pushes the sliding rod 62 to move outward according to the position of the heat shrink tubing, thereby tautening the heat shrink tubing and the roller assembly 64. At the same time, the roller assembly 64 can slide left and right in the groove 63 to prevent the heat shrink tubing at the edge of the take-up drum 58 from breaking when it is clamped by the roller assembly 64, thus achieving the effect of slow unwinding and preventing breakage.
