Description

Technical Field

[0001] The present invention relates to the technical field of automobile wire harness processing, in particular to an automatic casing device for automobile wire harness processing. Background Art

[0002] The automotive wiring harness is a core component of the automotive electrical system. It is an integrated cable assembly composed of wires, connectors, terminals, insulating protective materials (such as sleeves and tapes), etc. It is responsible for transmitting power and signals between various components of the vehicle, which is equivalent to the "neural network" of the car.

[0003] Automotive wiring harness conduit is more than just "outer packaging"; it's a systematic solution that integrates materials science, structural design, and functional requirements. Its ultimate goal is to ensure stable power and signal transmission throughout the vehicle's lifecycle while reducing the risk of recalls and safety incidents caused by wiring harness failures. During the conduit processing process, for some softer wires that require multiple conduits simultaneously, the ends of semi-finished wires often have burrs. When the wires are directly threaded through the conduit, their ends can get stuck on the inner wall of the conduit, making it difficult to quickly insert the entire wire harness into the conduit in one go. This results in low conduit processing efficiency. Furthermore, current conduit processing equipment, when cutting and applying the conduit, simply squeezes the ends of the conduit to open it, resulting in poor stability. During the squeezing and opening process, if the ends of the conduit are tightly bonded after cutting, the upper and lower layers of the conduit bend toward the same side, preventing the ends from being stretched and making it difficult to apply the conduit. Therefore, we have proposed an automatic conduit processing device for automotive wiring harnesses to address these issues. Summary of the Invention

[0004] The present invention aims to provide an automatic sleeve processing device for automobile wire harnesses to address the defect in the prior art that some wire harnesses which are relatively soft and require multiple sleeves at the same time cannot be continuously and smoothly passed through the protective tube by relying solely on the extrusion and transportation of the conveyor belt.

[0005] The present invention is achieved through the following technical solutions: An automatic conduit-sleeving device for processing automotive wire harnesses includes a base plate, a guide rod disposed on the base plate, a clamping portion disposed at one end of the guide rod, a first clamping mechanism and a second clamping mechanism disposed on the outer sides of each end of the guide rod, respectively, for clamping the guide rod at different time periods, and a cutting mechanism and a guiding mechanism for processing a wire harness protective tube disposed on a side of the guide rod away from the clamping portion, the first clamping mechanism and the second clamping mechanism each being two in number and disposed on both sides of the end of the guide rod to cooperate in clamping the guide rod; A pushing mechanism is provided between the first clamping mechanism and the second clamping mechanism, the guide rod is inserted into the pushing mechanism, the pushing mechanism is slidably mounted on the bottom plate, and the pushing mechanism is used to push the wire harness protection tube; It also includes a control module, which is used to control the opening and closing of the first clamping mechanism and the second clamping mechanism. When the first clamping mechanism is opened, the second clamping mechanism is closed, and when the second clamping mechanism is opened, the first clamping mechanism is closed. At the same time, the control module controls the pushing mechanism to move at least twice in a single sleeve operation. During the first movement, the second clamping mechanism is opened and the first clamping mechanism is closed. The pushing mechanism clamps the end of the protective tube and moves it to the first clamping seat. At this time, the second clamping mechanism is closed to fix the guide rod, the first clamping mechanism is opened, and the pushing mechanism is released and reset, clamping the other end of the protective tube again and pushing the protective tube onto the wiring harness.

[0006] The cutting mechanism is provided with a shaping mechanism for shaping the end portion of the wire harness protection tube after cutting.

[0007] In a preferred embodiment of the present invention, the first clamping mechanism and the second clamping mechanism both include a mounting seat and a clamping cylinder fixed on the mounting seat, a clamping block is fixed to the telescopic end of the clamping cylinder, and the distance between the first clamping mechanism and the second clamping mechanism is greater than the length of the protective tube required for the automotive wiring harness to be sleeved, ensuring that after the protective tube is sleeved on the guide rod, when the first clamping mechanism or the second clamping mechanism is fixed or released, the other clamping mechanism performs the opposite operation and will not clamp the protective tube.

[0008] In a preferred embodiment of the present invention, the clamping portion includes a sliding sleeve mounted on the guide rod, a second spring is provided between the inner end of the sliding sleeve and the guide rod, and two matching clamps are hinged at the outer end of the guide rod. When the second spring is in a natural state, the sliding sleeve pushes the two clamps to close, and by placing one end of the wiring harness between the two clamps, the second spring pushes the sliding sleeve to squeeze the clamps to clamp and fix the wiring harness.

[0009] In a preferred embodiment of the present invention, a step is provided at the end of the guide rod, the sliding sleeve is sleeved on the step, and the diameter of the sliding sleeve is smaller than the diameter of the guide rod, thereby reducing interference when the protective tube is sleeved.

[0010] In a preferred embodiment of the present invention, the pushing mechanism includes a pushing cylinder and a slide plate, the pushing cylinder pushes the slide plate to move on the base plate, and an annular shell is fixed on the slide plate, an inner ring body is provided inside the annular shell, and a gear ring is rotatably installed inside the annular shell, and a plurality of first connecting rods are hinged on the inner side of the gear ring, and the other end of the first connecting rod passes through the inner ring body and is hinged to a clamping plate, and a first servo motor is installed on the outer wall of the annular shell, and a gear meshing with the gear ring is provided at the output end of the first servo motor, and the rotation of the gear drives the gear ring to rotate, and then drives the clamping plate to clamp the protective tube through the first connecting rod.

[0011] In a preferred embodiment of the present invention, the clamping plate is arranged in an arc shape, and the inner wall of the clamping plate is connected to a movable plate body through a first spring. The first spring allows a certain amount of movable protection to be retained after the protective tube is clamped to avoid hard clamping, so that the protective tube can move on the guide rod when the pushing mechanism moves.

[0012] In a preferred embodiment of the present invention, the cutting mechanism includes a cutting table fixed on a base plate, a top plate is fixed on the cutting table by a support, a telescopic cylinder is installed on the top plate, and a cutting knife adapted to the cutting table is installed at the telescopic end of the telescopic cylinder. The cutting knife is driven down by the operation of the telescopic cylinder to cooperate with the cutting table to cut off the protective tube.

[0013] In a preferred embodiment of the present invention, the shaping mechanism includes a base plate mounted on the cutting table and a suction cup slidably mounted on the cutting blade. A plurality of suction rollers are rotatably mounted on the base plate, and a second servo motor is fixed to the outer end of the base plate to drive all the suction rollers to rotate. The suction rollers are hollow and have suction holes evenly formed on them. One end of the suction roller is connected to a first suction pipe via a rotary joint. One side of the cutting knife is provided with a slot arranged in the up and down directions, one end of the above-mentioned suction cup is inserted in the slot, and a third spring is provided between the end of the suction cup and the top end surface of the slot, and one side of the suction cup is provided with a second suction pipe connected to an external negative pressure pump. After the protective tube is cut, the lower layer of the protective tube is adsorbed by the adsorption roller, and at the same time, the upper layer of the protective tube is adsorbed by the suction cup, and when the cutting knife rises, the suction cup is driven to rise, thereby pulling open the port of the protective tube, and the adsorption roller is driven to rotate again by the operation of the second servo motor to transport the protective tube so that it is sleeved on the guide rod.

[0014] In a preferred embodiment of the present invention, the plurality of adsorption rollers are arranged linearly, and a driven sprocket is fixed to one end of the adsorption roller, a driving sprocket is fixed to the second servo motor, and the driving sprocket is connected to the driven sprocket via a chain; Two limiting sprockets are provided between two adjacent adsorption rollers. The two limiting sprockets are respectively located on the upper and lower sides of the chain. The position of the chain is limited by the limiting sprockets to prevent it from separating from the driving sprocket and the driven sprocket.

[0015] In a preferred embodiment of the present invention, the guide mechanism includes a mounting plate fixed on the base plate, and two guide rollers that cooperate with each other are provided on the mounting plate. The two guide rollers are used to limit the left and right positions of the protective tube to reduce its offset during movement.

[0016] The beneficial effects of the present invention are: By adding a guide rod, this device first fixes the end of the wire harness between two clamping plates when threading the wire harness, so that the end of the wire harness is located inside the clamping plates, and then threads the protective sleeve. This can avoid the problem of the wire harness being stuck on the inner wall of the protective tube due to burrs on the end of the semi-finished wire harness during threading, improve the smoothness of the threading of the soft wire harness, and greatly improve the processing efficiency. After the protective tube is cut by the cutting knife, the device uses the adsorption roller and the suction cup to adsorb the upper and lower layers of the protective tube respectively, and drives the suction cup to rise as the cutting knife rises, pulling open the end of the cut protective tube to expand it, thereby facilitating the protective tube to be sleeved on the guide rod, which is equivalent to the existing method of squeezing and stretching the two sides of the protective tube, improving stability and facilitating the operation of the wire harness sleeve.

[0017] In this application, the adsorption roller has the function of stretching the end of the protective tube, and can also transport the protective tube by driving the rotation of the adsorption roller through the second servo motor. The adsorption effect increases the friction between the adsorption roller and the protective tube, making its transportation more stable. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the directional terms used are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0021] like Figure 1-9 The automatic sleeve equipment for processing automotive wiring harnesses shown in the figure includes a base plate 1, a guide rod 8 is provided on the base plate 1, and a step is provided at the end of the guide rod 8 (the shape is two sections of cylinders with different diameters but coaxially arranged, which are combined to form the guide rod 8). One end of the guide rod 8 is provided with a clamping portion for fixing multiple wiring harnesses, and the clamping portion includes a sliding sleeve 81 sleeved on the guide rod 8, the sliding sleeve 81 is sleeved on the stepped surface, and the diameter of the sliding sleeve 81 is smaller than the diameter of the main body of the guide rod 8 (here refers to the diameter of the guide rod 8 with a larger diameter, specifically as shown in FIG. Figure 2 As shown), to reduce interference when installing the protective tube; The second spring 82 is fixed to the end of the sliding sleeve 81, and the other end of the second spring 82 is fixed to the stepped surface on the guide rod 8. The sliding sleeve 81 can move on the small diameter section on the guide rod 8 and squeeze the second spring 82 when it moves toward the side of the guide rod 8 body. The second spring 82 is in a natural state, and the sliding sleeve 81 is sleeved on the circular tube formed by the two splints 83, which pushes the two splints 83 to close. By placing one end of the wiring harness between the two splints 83, the second spring 82 pushes the sliding sleeve 81 to squeeze the splint 83 to clamp the wiring harness. Among them, the outer sides of both ends of the guide rod 8 are respectively provided with a first clamping mechanism 2 and a second clamping mechanism 3, which are used to clamp the guide rod 8 at different time periods. The number of the first clamping mechanism 2 and the second clamping mechanism 3 are two, respectively, which are arranged on both sides of the end of the guide rod 8 and can cooperate to clamp the guide rod 8 (when the first clamping mechanism 2 clamps the guide rod 8, the second clamping mechanism 3 is opened, and vice versa). The first clamping mechanism 2 and the second clamping mechanism 3 both include a mounting seat 21 and a clamping cylinder 22 fixed on the mounting seat 21. The telescopic end of the clamping cylinder 22 is fixed with a clamping block 23, and the distance between the first clamping mechanism 2 and the second clamping mechanism 3 is greater than the length of the protective tube required for the automotive wiring harness to be sleeved, ensuring that after the protective tube is sleeved on the guide rod 8, when the first clamping mechanism 2 or the second clamping mechanism 3 is opened or closed, the other clamping mechanism performs the opposite operation and does not clamp the protective tube; A pushing mechanism 4 is provided between the first clamping mechanism 2 and the second clamping mechanism 3. The pushing mechanism 4 is slidably mounted on the base plate 1 and is used to push the wiring harness protective tube. The pushing mechanism 4 includes a pushing cylinder 7 and a slide plate 9. The pushing cylinder 7 pushes the slide plate 9 to move on the base plate 1, and an annular shell 41 is fixed on the slide plate 9. An inner ring body 43 is provided inside the annular shell 41. The guide rod 8 is inserted in the inner ring body 43, and a gear ring 42 is rotatably installed inside the annular shell 41. A plurality of first connecting rods 45 are hinged to the inner side of the gear ring 42. The other end of the first connecting rod 45 passes through the inner ring body 43 and is hinged to a clamping plate 44. A first servo motor 46 is installed on the outer wall of the annular shell 41. A gear 47 meshing with the gear ring 42 is provided at the output end of the first servo motor 46. The rotation of the gear 47 drives the gear ring 42 to rotate, and then drives the clamping plate 44 to clamp the protective tube through the first connecting rod 45; Furthermore, the clamping plate 44 is arranged in an arc shape, and the inner wall of the clamping plate 44 is connected to the movable plate body 441 via a first spring 442. The first spring 442 allows a certain degree of movable protection to be retained after the protective tube is clamped, thereby avoiding rigid clamping. As a result, the protective tube can move on the guide rod 8 when the pushing mechanism 4 moves. In order to facilitate better movement of the protective tube, silicone bumps can be provided on the inner wall of the movable plate body 441, and the surface of the guide rod 8 is polished. Secondly, a cutting mechanism 5 for cutting the wire harness protection tube is provided on the side of the guide rod 8 away from the clamping portion. The cutting mechanism 5 is provided with a shaping mechanism 55 for pulling open the end of the protection tube after cutting. Specifically, the cutting mechanism 5 includes a cutting table 51 fixed on the base plate 1, a top plate 52 is fixed on the cutting table 51 by a support, a telescopic cylinder 53 is installed on the top plate 52, and a cutting knife 54 adapted to the cutting table 51 is installed at the telescopic end of the telescopic cylinder 53. The cutting knife 54 is driven down by the operation of the telescopic cylinder 53, so that it cooperates with the cutting table 51 to cut off the protective tube.

[0022] The shaping mechanism 55 includes a base plate 551 mounted on the cutting table 51 and a suction cup 558 slidably mounted on the cutting blade 54. A plurality of suction rollers 552 are rotatably mounted on the base plate 551, and a second servo motor 553 is fixed to the outer end of the base plate 551 to drive all the suction rollers 552 to rotate. The plurality of suction rollers 552 are linearly arranged, and a driven sprocket 555 is fixed to one end of the suction roller 552. A driving sprocket 554 is fixed to the second servo motor 553, and the driving sprocket 554 is connected to the driven sprocket 555 through a chain 556. Two limiting sprockets 557 are provided between two adjacent suction rollers 552. The two limiting sprockets 557 are respectively located on the upper and lower sides of the chain 556. The position of the chain 556 is limited by the limiting sprocket 557 to prevent it from separating from the driving sprocket 554 and the driven sprocket 555. The operation of the second servo motor 553 drives all the suction rollers 552 to rotate, thereby conveying the protective tube. The adsorption roller 552 is hollow and has adsorption holes 5521 evenly formed thereon. One end of the adsorption roller 552 is connected to a first suction pipe 5522 via a rotary joint 5523 . The first suction pipe 5522 is connected to an external negative pressure pump. Secondly, a slot 541 arranged in the up and down directions is provided on one side of the cutting knife 54, one end of the above-mentioned suction cup 558 is inserted in the slot 541, and a third spring 542 is provided between the end of the suction cup 558 and the top end surface of the slot 541, and a second suction pipe 5581 connected to an external negative pressure pump is provided on one side of the suction cup 558. After the protective tube is cut, the lower layer of the protective tube is adsorbed by the adsorption roller 552, and at the same time, the upper layer of the protective tube is adsorbed by the suction cup 558. When the cutting knife 54 rises, the suction cup 558 is driven to rise, thereby pulling open the port of the protective tube, and the adsorption roller 552 is driven to rotate again by the operation of the second servo motor 553 to transport the protective tube so that it is sleeved on the guide rod 8.

[0023] The outer end of the cutting mechanism 5 is provided with a guide mechanism 6 for limiting the protective tube. The guide mechanism 6 includes a mounting plate 61 fixed on the base plate 1. Two guide rollers 62 that cooperate with each other are provided on the mounting plate 61. The left and right positions of the protective tube are limited by the two guide rollers 62 to reduce the offset phenomenon during its movement.

[0024] It also includes a control module, which is used to control the opening and closing of the first clamping mechanism 2 and the second clamping mechanism 3. When the first clamping mechanism 2 is opened, the second clamping mechanism 3 is closed, and when the second clamping mechanism 3 is opened, the first clamping mechanism 2 is closed. At the same time, the control module controls the pushing mechanism 4 to move at least twice in a single sleeve operation. During the first movement, the second clamping mechanism 3 is released, the first clamping mechanism 2 is fixed, and the pushing mechanism 4 clamps the end of the protective tube and moves it to the first clamping mechanism 2. At this time, the second clamping mechanism 3 fixes the guide rod 8, the first clamping mechanism 2 is released, and the pushing mechanism 4 is released and reset, clamping the other end of the protective tube again, and pushing the protective tube onto the wiring harness.

[0025] In this embodiment, the sliding sleeve 81 is pushed to squeeze the second spring 82, so that the clamping plates 83 are opened. After one end of the wiring harness is placed between the two clamping plates 83, the sliding sleeve 81 is released. The second spring 82 pushes the sliding sleeve 81 to squeeze the clamping plates 83, thereby closing the clamping plates 83 and fixing the wiring harness. Insert the protective tube (a flat heat-shrink tube) into the guide mechanism 6, move it to the base plate 551 on the cutting table 51, and sleeve it onto the guide rod 8 (the second clamping mechanism 3 is now open and the first clamping mechanism 2 is closed. Manual sleeve placement of the protective tube onto the guide rod 8 only needs to be performed during equipment commissioning and does not require manual sleeve placement during subsequent processing). The suction roller 552 and the suction cup 558 are opened, and the telescopic cylinder 53 is opened to drive the cutting knife 54 to descend and cut the protective tube. During the process of the cutting knife 54 descending and cutting, the suction cup 558 descends and absorbs the upper layer of the protective tube (the third spring 542 is squeezed during the descent process, so that the cutting knife 54 can continue to descend without causing cutting interference). After cutting, the telescopic cylinder 53 drives the cutting knife 54 to return to its original position. During the reset process, it drives the suction cup 558 to pull open the end of the cut protective tube. After one second of being pulled open, the suction cup 558 stops working, and the suction force at the upper end disappears. After the protective tube is cut, the first servo motor 46 drives the gear 47 to rotate, and the gear 47 drives the gear ring 42 to rotate, and then drives all the clamping plates 44 to move toward the middle through the first connecting rod 45 to clamp the protective tube. After clamping, the push cylinder 7 drives the annular shell 41 to move forward a distance, so that one end of the protective tube moves to the first clamping mechanism 2 (at this time, the protective tube is located between the first clamping mechanism 2 and the second clamping mechanism 3). At the same time, the second clamping mechanism 3 closes to clamp the guide rod 8, and the first clamping mechanism 2 Open, the first servo motor 46 rotates in the opposite direction, driving the clamping plate 44 to loosen, and the pushing cylinder 7 drives the annular shell 41 to reset, and the clamping operation is performed again, and the protective tube is pushed forward by the pushing cylinder 7 again, so that the protective tube is sleeved on the wire harness, and the sliding sleeve 81 is pushed again to open the clamping plate 83 so that the wire harness with the sleeve completed can be removed. The guide rod 8 is used to guide the wire harness when it is sleeved, thereby improving the smoothness of the softer wire harness when it is passed through, avoiding the situation where the wire harness is stuck inside the protective tube, and greatly improving the processing efficiency.

[0026] After a single sleeve is completed, at the same time, the second servo motor 553 runs, driving all the adsorption rollers 552 to rotate, and transporting the protective tube after the ends are pulled open, so that the protective tube can be sleeved on the guide rod 8. The adsorption effect increases the friction between the adsorption roller 552 and the protective tube, making its transportation more stable for the next sleeve operation.
