Description

Technical Field

[0001] This invention relates to the technical field of electrical component processing, and in particular to a busbar heat shrink sleeve installation device. Background Technology

[0002] In electrical equipment such as distribution cabinets, high and low voltage switchgear, and transformers, heat shrink sleeves need to be installed on the busbars used in these devices to meet requirements for electrical insulation, personal safety, corrosion prevention, and extended service life.

[0003] Existing technology uses manual installation of heat shrink sleeves, which usually requires multiple workers. Since finished heat shrink sleeves are usually stored in rolls and are compressed after long-term transportation, some workers are responsible for holding and unfolding the heat shrink sleeves and cutting them, while others are responsible for moving the busbars and inserting them into the heat shrink sleeves. After the heat shrink sleeves are put on the busbars, they need to be placed on a rack and manually heated evenly using a propane spray gun or hot air blower. Overall, the current installation method is inefficient. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a busbar heat shrink sleeve installation device that can automatically install and heat-cure busbars with heat shrink sleeves, thereby improving production efficiency.

[0005] In order to achieve the objectives of this invention, the following technologies are proposed:

[0006] A busbar heat shrink sleeve installation device, comprising:

[0007] The unwinding guide unit includes an unwinding assembly for placing the rolled heat shrink sleeve, and a guide assembly for leading the heat shrink sleeve out of the unwinding assembly and guiding it horizontally.

[0008] The assembly unit is located above the unwinding guide unit and includes a second linear mechanism parallel to the horizontal conveying direction of the heat shrink sleeve. A pair of first rotary motors are provided below the sliding end of the mechanism. A rotating rod is provided at the output end of the first rotary motor. Several rotating blocks are fixed on the outer periphery of the rotating rod. A support shovel for spreading the heat shrink sleeve is provided at one end of the rotating block.

[0009] The busbar feeding unit is located at one end of the unwinding guide unit and is used to feed the busbar from the opposite direction to the horizontal conveying direction of the heat shrink tubing.

[0010] The cutting unit, located on one side of the unwinding guide unit, is used to cut the heat shrink sleeve;

[0011] The transfer unit is located on one side of the unwinding guide unit and includes a fifth linear mechanism whose output direction is parallel to the third linear mechanism. Its output end is provided with a clamping device for clamping the mother bar that has been fitted with heat shrink sleeve.

[0012] The heating unit, located on the other side of the unwinding guide unit, is used to heat the heat shrink sleeve fitted on the busbar.

[0013] Furthermore, the unwinding assembly includes a first base, a first baffle is provided on the upper part of one side of the first base, a fixing rod for placing the heat shrink sleeve is provided on one side of the first baffle, and a first fixing seat is provided on the lower part of one side of the first base, which has a vertical through hole. The unwinding assembly also includes a trolley, a second base is provided on the upper end of the trolley, a second baffle is provided on the upper part of one side of the second base, and a second fixing seat is provided on one end of the trolley, which also has a vertical through hole. The upper end face of the first fixing seat and the lower end face of the second fixing seat are located on the same plane.

[0014] Furthermore, the guide assembly includes a pair of vertical plates, with two sets of guide rollers disposed between the two vertical plates.

[0015] Furthermore, one side of the guide assembly is also provided with multiple support components arranged in an array along the conveying direction of the heat shrink sleeve during operation. The support components include a vertically arranged first linear mechanism, the output end of which is provided with a U-shaped frame, and multiple support rollers are provided between the two vertical parts of the U-shaped frame.

[0016] Furthermore, the sliding end of the second linear mechanism is provided with a hanging plate, the lower end of the hanging plate is provided with a pair of side plates, the lower end of the side plates is provided with a mounting seat, the upper end of one mounting seat is provided with a bracket and the lower end is provided with a rotating seat, the upper end of the other mounting seat is provided with a rotating seat and the lower end is provided with a bracket, a first rotary motor is provided at the upper end of one bracket, and another first rotary motor is provided at the lower end of the other bracket, and the rotating rod is rotated and engaged with the rotating seat.

[0017] Furthermore, the busbar feeding unit includes a conveyor belt with a limiting plate mounted on its upper end.

[0018] Furthermore, the cutting unit includes a third linear mechanism whose output direction is parallel to the width direction of the busbar, and a vertical fourth linear mechanism at its output end. The output end of the fourth linear mechanism is equipped with a second rotary motor, and the output end of the second rotary motor is equipped with a circular saw blade.

[0019] Furthermore, the heating unit includes a pair of placement plates, and a sixth linear mechanism is provided on one side of the placement plate. The sliding end of the mechanism is provided with a pair of oppositely arranged heating devices. When a busbar with a heat shrink sleeve is placed on the placement plate, the heating medium outlets of the two heating devices face the upper and lower ends of the busbar, respectively.

[0020] The beneficial effects of this technical solution are as follows:

[0021] 1. The assembly unit opens the opening of the heat shrink sleeve and moves it in one direction, while the busbar feeding unit moves the busbar in the opposite direction. The busbar and the heat shrink sleeve move simultaneously, which allows for faster application of the heat shrink sleeve.

[0022] 2. After the heat shrink sleeve is fitted onto the busbar, it can be automatically transferred and heated simultaneously from both the top and bottom sides, saving manpower.

[0023] 3. The assembly unit also automatically drags the heat shrink tubing, and the cutting unit cuts the rolled heat shrink tubing into a certain length, further improving the level of automation. Attached Figure Description

The upper end face of the first fixing seat 113 and the lower end face of the second fixing seat 123 are on the same plane. When assembling the unwinding assembly, the heat shrink sleeve 7 is first placed on the fixing rod 112, and then the trolley 12 is moved so that one end of the fixing rod 112 abuts against one side of the second baffle 122, and at this time the vertical through hole of the first fixing seat 113 is opened. The vertical through holes of the through hole and the second fixed seat 123 are coaxial. A pin 124 is inserted into the two vertical through holes to fix the unwinding assembly. The unwinding guide unit 1 also includes a guide assembly for guiding the heat shrink sleeve 7 out of the unwinding assembly and guiding it horizontally. The guide assembly includes a pair of vertical plates 13. Two sets of first rotating grooves are opened on the vertical plates 13.

The output end of the first rotary motor 24 is provided with a rotating rod 25 that is rotatably engaged with the rotating seat 234. Several rotating blocks 26 are fixed on the outer periphery of the rotating rod 25. One end of the rotating block 26 is provided with a support shovel 27 for spreading the heat shrink sleeve.

[0038] like Figure 1, Figure 6 As shown, the busbar feeding unit 3 is located at one end of the unwinding guide unit 1 and is used to feed the busbar 8 from a direction opposite to the horizontal conveying direction of the heat shrink sleeve 7. 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In this embodiment, the first linear mechanism 15, the third linear mechanism 42, the fourth linear mechanism 45, and the fifth linear mechanism 52 are all single-axis linear cylinders or linear hydraulic cylinders, the second linear mechanism 22 and the sixth linear mechanism 65 are both rodless linear cylinders or electric guide rails, the clamping device 53 is a pneumatic vise, and the heating device 66 is a hot air blower.

[0043] Work style:

[0044] First, the rolled heat shrink sleeve 7 is placed on the unwinding guide unit 1. The specific placement method has been explained previously. Then, the heat shrink sleeve 7 is manually passed between the two sets of guide rollers 14. Next, the assembly unit 2 opens the opening of the heat shrink sleeve 7. Specifically, the two first rotary motors 24 are moved by the second linear mechanism 22. First, the support shovels 27 controlled by the two first rotary motors 24 are brought close together or their tips are in contact. Then, the second linear mechanism 22 moves the support shovels 27 into the opening of the heat shrink sleeve 7. Then, the first rotary motors 24 rotate the rotating block 26, so that the support shovels 27 open the opening of the heat shrink sleeve 7 on the one hand, and drag the heat shrink sleeve 7 on the other hand, so that the second linear mechanism 22 can drag and move the heat shrink sleeve 7.

[0045] Simultaneously, workers place several busbars 8 sequentially onto the conveyor belt 31, causing both the busbars 8 and the heat shrink sleeves 7 to move. Specifically, the busbars 8 are positioned between the two mounting seats 232 in the height direction. When the components controlled by the sliding end of the second linear mechanism 22 move, the busbars 8 will enter the openings of the heat shrink sleeves 7. Since the positions of the holes on the busbars 8 do not require the heat shrink sleeves 7, the heat shrink sleeves 7 fitted onto the busbars 8 should be shorter than the busbars 8. Therefore, the heat shrink sleeves 7 should be cut off before complete installation. The fourth linear mechanism 45 pushes the components at its output end. Since the components under the second linear mechanism 22 have already moved a certain distance, there will be no interference. The second rotary motor 46 makes the circular saw blade 47 rotate. When the circular saw blade 47 is above the heat shrink sleeve 7 without the mother bar 8 inside, the fourth linear mechanism 45 lowers the circular saw blade 47 so that it cuts the heat shrink sleeve 7. The cutting groove 49 can provide support, making the cutting smoother. After the cutting is completed, the fourth linear mechanism 45 retracts the components at its output end.

[0046] After the heat shrink sleeve 7 is installed on the busbar 8, the clamping device 53 is pushed by the fifth linear mechanism 52 to clamp the heat shrink sleeve 7 and the busbar 8 as a whole. 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 retracted by the fifth linear mechanism 52. The whole falls on the placement plate 62, specifically between the two C-shaped parts 63.

[0047] Two heating devices 66 are activated, and the sixth linear mechanism 65 moves the two heating devices 66 from one end of the heat shrink sleeve 7 to the other end for heating. Specifically, while heating is being performed, the heat shrink sleeve 7 can be simultaneously applied to the next busbar 8, achieving continuous production.

[0048] The above are only some of the embodiments listed in this application and are not intended to limit this application.
