Description

Technical Field

[0001] The invention belongs to the technical field of wire harness production, and in particular relates to a wire stripping device for automobile wire harness processing. Background Art

[0002] The wiring harness is the wiring component that connects various electrical devices in the circuit, and is composed of insulating sheath, terminal blocks, wires and insulating wrapping materials. The wiring harness is the wiring component that connects various electrical devices in the circuit, and is composed of core wire, insulation, braiding and outer sheath. The quality of the wiring harness is directly related to whether the entire electrical equipment can work normally and safely.

[0003] At present, one of the important links in the production and processing of wire harnesses is to peel the ends of the wire harnesses. The ends of the wire harnesses are peeled by a wire stripping mechanism so that the inner core of the ends of the wire harnesses is exposed for later wiring. The existing stripping method is usually performed by staff using tools such as pliers, which is inefficient. When the number of wire harnesses is large, only manual methods are used, which is not only inefficient but also labor-intensive.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] For the first specific embodiment, please refer to Figure 1-16, the present invention is a wire stripping device for automobile wire harness processing, including a wire harness 1, a feeding conveying mechanism 2 and a discharging conveying mechanism 3; a wire stripping mechanism 4 is arranged between the feeding conveying mechanism 2 and the discharging conveying mechanism 3; the wire stripping mechanism 4 includes a frame 5; two guiding plates 6 are symmetrically fixed on the frame 5; conveying assemblies 7 are respectively arranged between the two guiding plates 6 and the frame 5; the conveying assembly 7 includes two rotating shafts 8 rotatably arranged between the frame 5 and the guiding plate 6; two wire stripping conveyor rollers 9 are symmetrically fixed on the circumferential side of the rotating shaft 8 near both ends; a first conveyor belt 10 and a second conveyor belt 11 which are in transmission cooperation with the corresponding wire stripping conveyor rollers 9 are arranged between the two rotating shafts 8; the first conveyor belt 10 is close to the side surface of the frame 5; the second conveyor belt 11 is close to the side surface of the guiding plate 6; a number of U-shaped clamping plates 12 are uniformly fixed on the outer surfaces of the first conveyor belt 10 and the second conveyor belt 11; the U-shaped clamping plates 12 on the two conveying assemblies 7 are respectively grouped in pairs; the wire harness 1 is located between the two U-shaped clamping plates 12; the outer diameter of the gap formed between the inner walls of the two U-shaped clamping plates 12 is larger than the outer diameter of the wire harness 1; a guiding track is arranged on the circumferential side of the guiding plate 6; the guiding track includes a first straight track 13 and a first arc track 14 which are communicated with each other; the distance between the first straight track 13 and the conveying assembly 7 is constant; the distance between the first arc track 14 and the conveying assembly 7 first increases and then decreases; the first arc track 14 bends towards the direction away from the conveying assembly 7; a wire stripping member 15 is slidably arranged on the inner wall of the guiding track; the wire stripping member 15 is slidably matched with the adjacent U-shaped clamping plate 12.

[0042] Specifically, two conveying gears 33 are rotatably arranged on the side surface of the frame 5; the two conveying gears 33 are meshed with each other; the two conveying gears 33 are respectively fixedly connected with the rotating shafts 8 on the two conveying assemblies 7; a third servo motor 34 is fixedly arranged on the side surface of the frame 5; the output end of the third servo motor 34 is fixedly connected with one of the conveying gears 33.

[0043] The working principle of this embodiment is as follows: First, start the third servo motor 34 to drive the corresponding conveying gear 33 to rotate, and then drive the other conveying gear 33 to rotate. Then, the two conveying gears 33 drive the corresponding conveying assemblies 7 to rotate. For example, Figure 8 , the upper conveying gear 33 rotates clockwise and the lower conveying gear 33 rotates counterclockwise. From Figure 1 's perspective, the upper conveying assembly 7 rotates counterclockwise and the lower conveying assembly 7 rotates clockwise. Then, place the wire harness 1 on the feeding conveying mechanism 2, and the feeding conveying mechanism 2 conveys the wire harness 1 towards the wire stripping mechanism 4.

[0044] During the rotation of the conveying gear 33, the corresponding rotating shaft 8 is driven to rotate, and then the wire stripping conveying roller 9 thereon is driven to rotate, and then the first conveyor belt 10 and the second conveyor belt 11 are moved, driving the U-shaped clamping plate 12 thereon to move. When the two U-shaped clamping plates 12 on the upper and lower conveying components 7 are close to the feed conveying mechanism 2, the wire harness 1 is conveyed between the two U-shaped clamping plates 12, and the two U-shaped clamping plates 12 clamp the wire harness 1 for conveying, and at the same time, the wire stripping piece 15 on the U-shaped clamping plate 12 clamps the end of the wire harness 1.

[0045] The conveying assembly 7 continues to rotate, driving the wire stripping piece 15 to first slide on the inner wall of the first straight track 13, and then slowly enter the first curved track 14. During the sliding process of the wire stripping piece 15 on the inner wall of the first curved track 14, since the distance between the first curved track 14 and the conveying assembly 7 first increases and then decreases, the wire stripping piece 15 pulls the cut part of the insulating sheath in the direction away from the conveying assembly 7, so that the insulating sheath is separated from the wiring harness 1. When the wire stripping piece 15 reaches the position of the first curved track 14 farthest from the conveying assembly 7, the part of the insulating sheath that needs to be cut off is completely pulled out, and then the insulating sheath is recovered. Then the wire stripping piece 15 slowly enters the first straight track 13 from the first curved track 14. When the two U-shaped clamps 12 approach the discharge conveying mechanism 3, the two U-shaped clamps 12 slowly move away from the loosened wiring harness 1. At this time, the wiring harness 1 falls onto the discharge conveying mechanism 3 and is conveyed to the next process for processing. The wire stripping device realizes the continuous feeding, cutting, stripping and discharging of the wiring harness 1.

[0046] For specific embodiment 2, please refer to Figure 1-16 On the basis of the specific embodiment 1, the feed conveying mechanism 2 includes a feed rack 16; the feed rack 16 is fixed to the surface of the frame 5 by fastening bolts; two feed conveying rollers 17 are symmetrically arranged between the two opposite inner walls of the feed rack 16 for rotation; a feed conveyor belt 18 is arranged between the two feed conveying rollers 17 for transmission; a first servo motor 19 is fixed to the side of the feed rack 16; and the output end of the first servo motor 19 is fixedly connected to a feed conveying roller 17.

[0047] Specifically, a feed arc frame 20 is fixed on the side of the frame 5 close to the feed rack 16; an arc cutting knife 21 is fixed on the inner wall of the feed arc frame 20; the top of the feed arc frame 20 faces the feed rack 16, and its bottom end faces the conveying assembly 7; an arc plate 22 is fixed on the side of the frame 5; the arc plate 22 is connected to the bottom of the feed arc frame 20; the arc plate 22 is coaxial with the wire stripping conveyor roller 9.

[0048] Furthermore, an arc groove 23 is opened on the side of the frame 5; the arc groove 23 is connected to the inside of the feed arc frame 20; an inner toothed ring 24 is fixed to the inner wall of the arc groove 23; a connecting plate 25 is fixed to the surface of the frame 5; a rotating plate 26 is rotatably provided on the side of the connecting plate 25; a feed gear 27 that meshes with the inner toothed ring 24 is rotatably provided on the side of the rotating plate 26.

[0049] Further, a Z-shaped pipe 28 is fixed to the side of the feeding gear 27; a hollow C-shaped plate 29 is fixed to the end of the Z-shaped pipe 28; the inner wall of the hollow C-shaped plate 29 is adapted to the circumferential side surface of the wire harness 1; a plurality of suction holes 30 communicating with the inside of the hollow C-shaped plate 29 are evenly formed in the inner wall of the hollow C-shaped plate 29; a gas delivery pipe 31 is fixed to the side of the feeding gear 27; the gas delivery pipe 31 penetrates through the rotating plate 26; one end of the Z-shaped pipe 28 is communicated with the inside of the hollow C-shaped plate 29, and the other end thereof is communicated with the gas delivery pipe 31; a second servo motor 32 is fixed to the side of the connecting plate 25; and the output end of the second servo motor 32 is fixedly connected with the rotating plate 26.

[0050] The working principle of this embodiment is as follows: In the initial state, the inner wall of the hollow C-shaped plate 29 faces upward and the outer circumferential side surface faces downward, and the feeding gear 27 is located at the top of the feeding arc-shaped frame 20 and is close to the lower part of the feeding frame 16.

[0051] First, start the first servo motor 19 to drive the corresponding feeding conveyor roller 17 to rotate, thereby driving the feeding conveyor belt 18 to convey the wire harness 1. The wire harness 1 falls from the feeding conveyor belt 18 into the inside of the feeding arc-shaped frame 20 and stops on the inner wall of the hollow C-shaped plate 29. The gas delivery pipe 31 is externally connected to an air extraction pump, and the air extraction pump extracts air through the gas delivery pipe 31, thereby sucking the air along the suction holes 30, the inside of the hollow C-shaped plate 29, the Z-shaped pipe 28, the feeding gear 27, and the gas delivery pipe 31, and then adsorbing the wire harness 1 on the inner wall of the hollow C-shaped plate 29, adsorbing and fixing the wire harness 1 on the inner wall of the hollow C-shaped plate 29 to prevent it from rotating.

[0052] Then start the second servo motor 32 to drive the rotating plate 26 to rotate, thereby driving the feeding gear 27 to move from the top of the arc-shaped groove 23 to the bottom of the arc-shaped groove 23. During the process, the feeding gear 27 is driven to rotate by itself by the inner missing tooth ring 24, thereby driving the Z-shaped pipe 28 and the hollow C-shaped plate 29 to rotate, and then driving the wire harness 1 to rotate and move downward inside the feeding arc-shaped frame 20, so that the insulating sheath outside the wire harness 1 is initially cut by the arc-shaped cutter 21 to form an annular cut mark.

[0053] When the wire harness 1 moves to the part where the feeding arc-shaped frame 20 is connected to the arc-shaped plate 22, the U-shaped clamping plate 12 on the upper conveying component 7 just aligns with the bottom of the feeding arc-shaped frame 20. At this time, turn off the air extraction pump, and then the wire harness 1 is released from adsorption and falls on the inner wall of the U-shaped clamping plate 12. Then the U-shaped clamping plate 12 continues to move downward. During the process, the arc-shaped plate 22 blocks the wire harness 1 to prevent the wire harness 1 from falling out of the inner wall of the U-shaped clamping plate 12.

[0054] When the U-shaped clamping plate 12 aligns with the corresponding U-shaped clamping plate 12 on the lower conveying component 7, the two U-shaped clamping plates 12 clamp the wire harness 1. At the same time, the wire stripping member 15 on the U-shaped clamping plate 12 clamps the end of the wire harness 1, and the annular cut mark of the insulating sleeve is located between the U-shaped clamping plate 12 and the wire stripping member 15.

[0055] Then, the wire harness 1 is stripped on the wire stripping mechanism 4 and finally falls onto the discharging conveyor mechanism 3 and is conveyed into the next process for processing.

[0056] In this embodiment, a negative pressure adsorption treatment is performed on the wire harness 1 inside the feeding arc-shaped frame 20. By driving the rotating plate 26 to rotate, the feeding gear 27 is driven to move from the top of the arc-shaped groove 23 to the bottom of the arc-shaped groove 23. During this process, the feeding gear 27 is driven to rotate by itself by the inner toothless ring 24, thereby driving the Z-shaped tube 28 and the hollow C-shaped plate 29 to rotate, and further driving the wire harness 1 to rotate and move downward inside the feeding arc-shaped frame 20, so that the insulating sheath outside the wire harness 1 is initially cut by the arc-shaped cutter 21 to form a circular cut mark, realizing the circular cutting of the insulating sheath of the wire harness 1, which is beneficial to the subsequent wire stripping of the wire harness 1.

[0057] Specific Embodiment Three, please refer to Figure 1-16 , on the basis of Specific Embodiment One and Specific Embodiment Two, a fixing plate 35 is fixed on the side surface of the U-shaped clamping plate 12 close to the guide plate 6; the wire stripping member 15 includes a sliding frame 36 slidably arranged on the outer side surface of the fixing plate 35; a U-shaped wire stripping plate 37 is fixed on the side surface of the sliding frame 36; a guide shaft 38 is fixed on the side surface of the U-shaped wire stripping plate 37; a guide ball 39 is fixed at the end of the guide shaft 38; the guide ball 39 is adapted to the inner wall of the guide track.

[0058] Specifically, ventilation grooves 40 are formed in the inner walls of the U-shaped wire stripping plate 37 and the U-shaped clamping plate 12; an elastic diaphragm 41 is hermetically fixed on the inner wall of the ventilation groove 40; a plurality of anti-slip protrusions 42 are uniformly fixed on the side surface of the elastic diaphragm 41; air charging pipes 43 communicating with the inside of the ventilation groove 40 are fixedly penetrated through the side surfaces of the U-shaped wire stripping plate 37 and the U-shaped clamping plate 12; springs 44 are symmetrically fixed on the sliding frame 36; a partition plate 45 is fixed at the end of the spring 44.

[0059] The working principle of this embodiment is as follows: Before using the device, part of the gas is filled or discharged into the inner wall of the ventilation groove 40 through the air charging pipe 43, so that when the wire harness 1 is located between the two U-shaped clamping plates 12 and the two U-shaped wire stripping plates 37, the elastic diaphragm 41 tightly wraps the wire harness 1.

[0060] When the two U-shaped clamping plates 12 clamp the wire harness 1, at the same time, the U-shaped wire stripping plates 37 on the U-shaped clamping plates 12 clamp the end of the wire harness 1, and the partition plates 45 on the sliding frames 36 on the two U-shaped wire stripping plates 37 are squeezed by the springs 44 and enter the circular cut mark.

[0061] The conveying assembly 7 continues to rotate, driving the guiding ball 39 to slide along the inner wall of the first straight track 13 first, and then driving the U-shaped wire stripping plate 37 to slide along the inner wall of the first straight track 13. Then it slowly enters the first arc track 14. During the process of sliding along the inner wall of the first arc track 14, since the distance between the first arc track 14 and the conveying assembly 7 first increases and then decreases, the U-shaped wire stripping plate 37 slowly drives the sliding frame 36 to slide along the outside of the fixing plate 35 in the direction away from the conveying assembly 7, and drives the partition plate 45 on the sliding frame 36 to move together. The partition plate 45 is inside the annular notch, and drives the insulation sheath to be stripped to pull and separate from the wire harness 1 together. When the U-shaped wire stripping plate 37 reaches the position where the distance between the first arc track 14 and the conveying assembly 7 is the farthest, the part of the insulation sheath that needs to be cut off is completely pulled out, and then the insulation sheath is recycled. Then the U-shaped wire stripping plate 37 slowly enters the first straight track 13 from the first arc track 14. When the two U-shaped clamping plates 12 approach the discharging conveying mechanism 3, the two U-shaped clamping plates 12 slowly move away from each other to loosen the wire harness 1. At this time, the wire harness 1 falls onto the discharging conveying mechanism 3 and is conveyed to the next process for processing.

[0062] In this embodiment, when the wire stripping member 15 runs along the inner wall of the first straight track 13, the distance between the wire stripping member 15 and the conveying assembly 7 is constant, so there is no pulling force on the wire harness 1. When the wire stripping member 15 runs inside the first arc track 14, the wire stripping member 15 slowly drives the sliding frame 36 to slide in the direction away from the conveying assembly 7, and drives the partition plate 45 on the sliding frame 36 to move together. The partition plate 45 is inside the annular notch, and drives the insulation sheath to be stripped to pull and separate from the wire harness 1 together, realizing the automatic stripping of the insulation sheath of the wire harness 1.

[0063] Specific embodiment four, please refer to Figure 1-16 , on the basis of specific embodiment one, specific embodiment two and specific embodiment three, an L-shaped mounting plate 46 is fixed between the two guide plates 6; an electric telescopic rod 47 is fixed on the inner wall of the L-shaped mounting plate 46; the telescopic end of the electric telescopic rod 47 is fixed with a mounting frame 48; a suction pump 49 is fixed on the mounting frame 48; the suction end of the suction pump 49 is fixed with a suction pipe 50; the end of the suction pipe 50 is fixed with a sealing plate 51; a communication hole 52 is formed through the circumferential side of the suction pipe 50; a ring 53 is rotatably arranged on the circumferential side of the suction pipe 50; a through groove 54 is formed through the circumferential side of the ring 53; a connecting pipe 55 is fixedly penetrated through the circumferential side of the ring 53; a plurality of adsorption pipes 56 are fixedly penetrated through the end of the connecting pipe 55 in a circumferentially arrayed and evenly distributed manner; a cleaning track is formed on the side of the L-shaped mounting 46; the cleaning track includes a connected second straight track 57 and a second arc track 58; the second straight track 57 is close to the guide plate 6; a guide rod 59 is fixed on the circumferential side of the connecting pipe 55; the circumferential side of the guide rod 59 is adapted to the inner wall of the cleaning track.

[0064] Specifically, the discharging conveying mechanism 3 includes a discharging rack 60; the discharging rack 60 is fixed to the side of the frame 5 by fastening bolts; two discharging conveying rollers 61 are symmetrically arranged between the two opposite inner walls of the discharging rack 60; a discharging conveyor belt 62 is arranged for transmission between the two discharging conveying rollers 61; a fourth servo motor 63 is fixed to the side of the discharging rack 60; the output end of the fourth servo motor 63 is fixedly connected to a discharging conveying roller 61; a discharging arc frame 64 is fixed to the side of the frame 5; the top end of the discharging arc frame 64 faces between the two conveying components 7, and its top end faces the discharging rack 60.

[0065] The working principle of this embodiment is as follows: in the initial state, the guide rod 59 is located at the position of the second arc track 58 close to the electric telescopic rod 47, that is, the connecting pipe 55 is placed vertically downward, and the connecting hole 52 is connected to the through groove 54.

[0066] When the U-shaped stripping plate 37 reaches the position of the first curved track 14 farthest from the conveying assembly 7, the part of the insulating sheath that needs to be cut off is completely pulled out, and then the third servo motor 34 is turned off to stop the conveying assembly 7. At this time, the telescopic end of the electric telescopic rod 47 is driven to extend, driving the mounting frame 48, the suction pump 49, the suction pipe 50, the sealing plate 51, the connecting hole 52, the ring 53, the through groove 54, the connecting pipe 55, the adsorption pipe 56 and the guide rod 59 to move. The guide rod 59 first rotates and moves upward along the inner wall of the second curved track 58, and then drives the connecting pipe 55 to slowly turn from vertical downward placement to horizontal placement. At this time, the connecting hole 52 is aligned with the connecting pipe 55, and then the guide rod 59 enters the second straight track 57, so that the connecting pipe 55 maintains a horizontal state and enters between the inner walls of the insulating sheath. At this time, the suction pump 49 is started, and the suction pump 49 sucks the insulating sheath out from between the two U-shaped stripping plates 37 through the adsorption pipe 56.

[0067] Then the telescopic end of the electric telescopic rod 47 retracts, driving the guide rod 59 from the inside of the second straight track 57 into the inside of the second curved track 58, and finally returns to the initial vertical downward state. At this time, the connecting hole 52 is connected to the through groove 54, and the connecting pipe 55 loses the suction force of the suction pump 49. At this time, the suction pump 49 is turned off, and the insulating sheath falls downward and can be collected and recovered in a container.

[0068] When the two U-shaped clamps 12 approach the discharge arc frame 64, the two U-shaped clamps 12 slowly move away from the loosened wire harness 1. At this time, the wire harness 1 falls into the inner wall and falls from the bottom of the discharge arc frame 64 to the discharge conveyor belt 62. Then the fourth servo motor 63 is started to drive the corresponding discharge conveyor roller 61 to rotate, and then drive the discharge conveyor belt 62 to move, and the stripped wire harness 1 is transported to the next processing step.

[0069] In this embodiment, when the guide rod 59 runs inside the second straight track 57, the connecting pipe 55 is aligned with the insulating sheath, and the communication hole 52 is aligned with the connecting pipe 55, so that the connecting pipe 55 adsorbs the insulating sheath through the adsorption pipe 56. When the guide rod 59 runs inside the second arc track 58, the connecting pipe 55 changes from a horizontal placement to a vertically downward placement, and the communication hole 52 is misaligned with the connecting pipe 55 and communicates with the through slot 54, releasing the adsorption of the insulating sheath, realizing the automatic blanking and recycling of the insulating sheath.
