[0002] In power distribution cabinets, high-low voltage switch cabinets, transformers and other electrical equipment, in order to meet the requirements of electrical insulation, personal safety, corrosion prevention, and prolonging the service life, the busbar used in these devices needs to be installed with a heat-shrink sleeve.

[0003] The prior art adopts a manual installation of the heat-shrink sleeve, which usually requires multiple workers. Since the finished heat-shrink sleeve is usually placed in a roll, it is compressed after a long period of transportation. Therefore, some workers are responsible for holding and unfolding the heat-shrink sleeve and cutting the heat-shrink sleeve, and other workers are responsible for carrying the busbar and inserting it into the heat-shrink sleeve. After the heat-shrink sleeve is sleeved on the busbar, it needs to be placed on a shelf, and a propane spray gun or a hot air machine is manually used to uniformly heat the heat-shrink sleeve. In general, the current installation method is low in efficiency. SUMMARY

It includes a conveyor belt 31, with a limiting plate 32 mounted on its upper end. In the accompanying drawings, for ease of illustration, only two busbars 8 are conveyed on the conveyor belt 31. In actual operation, a longer conveyor belt 31 can be used to convey more busbars 8 simultaneously. Specifically, when a busbar 8 is conveyed to the end and is mostly outside the busbar feeding unit 3, the busbar 8 can be supported by the limiting plate 32 and the aforementioned support assembly to prevent it and the attached heat shrink sleeve 7 from sagging.

[0031] like Figure 1 , Figure 7 As shown, the cutting unit 4 is located on one side of the unwinding guide unit 1 and is used to cut the heat shrink sleeve 7. It includes several first brackets 41. The upper end of the first bracket 41 is provided with a third linear mechanism 42 whose output direction is parallel to the width direction of the busbar 8. The output end of the first bracket 41 is provided with an L-shaped frame 43. One side of the vertical part of the L-shaped frame 43 is provided with a connecting plate 44. One end of the connecting plate 44 is vertically provided with a fourth linear mechanism 45. The output end of the fourth linear mechanism 45 is provided with a second rotary motor 46. The output end of the second rotary motor 46 is provided with a circular saw blade 47. One side of the horizontal part of the L-shaped frame 43 is provided with a cutting frame 48. The upper part of one end face of the cutting frame 48 is provided with a cutting groove 49 that extends toward the third linear mechanism 42 and is located below the circular saw blade 47.

[0032] like Figure 1 , Figure 7 As shown, the transfer unit 5 is located on one side of the unwinding guide unit 1 and includes several second supports 51. The upper end of the second support 51 is provided with a fifth linear mechanism 52 whose output direction is parallel to the third linear mechanism 42. The output end of the fifth linear mechanism 52 is provided with a clamping device 53 for clamping the busbar 8 that has been fitted with heat shrink sleeve 7.

[0033] like Figure 1 , Figure 9 As shown, the heating unit 6 is located on the other side of the unwinding guide unit 1 and is used to heat the heat shrink sleeve 7 fitted on the busbar 8. It includes a pair of third brackets 61. The upper end of the third bracket 61 is provided with a placement plate 62. The upper end of the placement plate 62 is formed with a C-shaped part 63 for limiting the end of the busbar 8. Each third bracket 61 is provided with a fourth bracket 64 on one side. The upper end of the fourth bracket 64 is provided with a sixth linear mechanism 65. Its sliding end is provided with a pair of oppositely arranged heating devices 66. When the busbar 8 with the heat shrink sleeve 7 fitted is placed on the placement plate 62, the heating medium outlets 67 of the two heating devices 66 are respectively facing the upper end face and the lower end face of the busbar 8.

[0034] In this embodiment, the first linear mechanism 15, the third linear mechanism 42, the fourth linear mechanism 45, and the fifth linear mechanism 52 all adopt single-shaft linear cylinders or linear hydraulic cylinders, the second linear mechanism 22 and the sixth linear mechanism 65 all adopt rodless linear cylinders or electric guide rails, the clamping device 53 adopts a pneumatic vice, and the heating device 66 adopts a hot air blower.

[0035] Working mode: First, the coiled heat-shrink sleeve 7 is placed on the unwinding guide unit 1, and the specific placement method has been described above, and then the heat-shrink sleeve 7 is manually threaded between the two sets of guide rollers 14. Next, the opening of the heat-shrink sleeve 7 is pried open by the assembling unit 2. Specifically, the two first rotary motors 24 are moved by the second linear mechanism 22. First, the prying shovels 27 controlled by the two first rotary motors 24 are close to or have the tips in contact, and then the prying shovels 27 are inserted into the opening of the heat-shrink sleeve 7 by moving the second linear mechanism 22. Then, the prying shovels 27 are rotated by the first rotary motor 24, so that the prying shovels 27 open the opening of the heat-shrink sleeve 7 on one hand, and on the other hand, the heat-shrink sleeve 7 is dragged, so that the second linear mechanism 22 drags and moves the heat-shrink sleeve 7.

[0036] At the same time, the worker places a plurality of busbars 8 on the conveyor belt conveyor 31 in sequence, so that the busbars 8 and the heat-shrink sleeve 7 move. Specifically, the busbar 8 is located between the two mounting seats 232 in the height direction, and when the components controlled by the sliding end of the second linear mechanism 22 move, the busbar 8 will enter the opening of the heat-shrink sleeve 7. Since the position of the hole position of the busbar 8 does not need to be sleeved with the heat-shrink sleeve 7, the heat-shrink sleeve 7 sleeved on the busbar 8 should be shorter than the busbar 8, so the heat-shrink sleeve 7 should be cut off before being completely sleeved. Specifically, the components at the output end of the fourth linear mechanism 45 are pushed, and since the components under the second linear mechanism 22 have moved a distance at this time, no interference is caused. The circular saw blade 47 is rotated by the second rotary motor 46, and when the circular saw blade 47 is above the heat-shrink sleeve 7 of the busbar 8 inside, the circular saw blade 47 is lowered by the fourth linear mechanism 45 to cut the heat-shrink sleeve 7. The cutting groove 49 can provide support to make the cutting more smooth. After cutting is completed, the components at the output end of the fourth linear mechanism 45 are retracted.

[0037] After the heat-shrink sleeve 7 is completely sleeved on the busbar 8, the clamping device 53 is pushed by the fifth linear mechanism 52, the whole of the heat-shrink sleeve 7 and the busbar 8 is clamped by the clamping device 53, and then the whole is moved by the fifth linear mechanism 52. When the whole is above the placement plate 62, the clamping device 53 is released, and the whole is retracted by the fifth linear mechanism 52. The whole falls on the placement plate 62, specifically, between the two C-shaped parts 63.

[0038] The two heating devices 66 are started, and the sixth linear mechanism 65 is used to move the two heating devices 66 from one end of the heat-shrink sleeve 7 to the other end for heating. Specifically, while heating, the sleeving of the heat-shrink sleeve 7 on the next busbar 8 can be simultaneously performed, so as to realize continuous production.

[0039] The above merely illustrates some embodiments of the present application and is not used to limit the present application.
