Description

Technical Field

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

[0002] Wire harness processing often requires docking. Wire harness processing docking refers to connecting two or more wire harnesses together. Generally, after the processing of wire harnesses of corresponding specifications and sizes is completed, for the two wire harnesses that need to be docked, a certain length of exposed metal part needs to be reserved, and then the exposed metal parts of the two wire harnesses are welded together by welding.

[0003] When using the existing wire harness butt welding equipment, first place the exposed metal parts of the two wire harnesses between the welding head and the bottom mold used for supporting positioning to ensure that the exposed metal parts are located in the welding area, then control the welding head to descend, and weld the exposed metal parts. After welding is completed, remove the wire harness, and then wrap the wire harness insulation tape, or install a heat shrink tube and heat and shrink it to achieve insulation wrapping.

[0004] The shortcomings of the existing wire harness butt welding equipment are that although the existing wire harness butt welding equipment can quickly weld the metal conductor parts of two wire harnesses together, after the welding butt is completed, the butted wire harness needs to be manually removed, and then the exposed metal conductor part is individually wrapped with insulating tape, which is generally done manually, or the butted wire harness is sent to the heat shrink tube assembly equipment, and the heat shrink tube assembly equipment is operated separately to put the heat shrink tube on the metal conductor position of the wire harness, and heat and shrink it to achieve wrapping, that is, the metal conductor part of the butt wire harness needs to be insulated and wrapped separately, which makes the operation inconvenient and inconvenient to complete continuously, and easily affects the processing efficiency.

[0016] Beneficial effects of the present invention: 1.

In this way, the first U-shaped slide drives the push plate to push the heat shrinkable tube body to one side, and the second U-shaped slide relies on the clamping block to drag the clamped wire harness body to the other side, so that the exposed metal parts of the two wire harness bodies that are connected to each other are finally connected to the heat shrinkable tube body, which is convenient for completing the insulation wrapping process, and there is no need to separately drag the wire harness body and assemble the heat shrinkable tube body to the exposed metal position.

[0018] 3. The linkage lower pressure plate provided in the present invention descends, causing the second U-shaped slide to slide. When the wiring harness body is dragged, the linkage lower pressure plate also drives the rack to descend, and the rack drives the gear to rotate, thereby causing the provided screw to rotate, so that the two supporting sliders assembled on the screw slide apart to avoid interfering with the dragging of the wiring harness body.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 8 As shown, a wiring harness processing docking device includes a support seat 1, a laser welding machine 3 and a welding support mechanism, the welding support mechanism is arranged on the support seat 1, the welding support mechanism is used to support the metal exposed end of the wiring harness body 6, the laser welding machine 3 is aligned and arranged above the welding support mechanism, when two wiring harness bodies 6 need to be docked, the metal exposed ends of the two wiring harness bodies 6 are placed on the welding support mechanism and intersected together, and then the metal exposed ends of the two wiring harness bodies 6 are welded together by the laser welding machine 3; then they are taken down and the wiring harness bodies 6 are docked; It should be noted that the docking equipment disclosed in the present application is for processing and docking wire harness bodies 6 of the same specifications, that is, the length, diameter and other dimensions of each wire harness body 6 are equal, and the exposed length of the metal bare ends is also the same, and they are all batch-processed and formed by the same equipment.

[0024] The docking equipment also includes a lifting drive mechanism, a wire harness dragging mechanism and a heat shrink tube conveying mechanism; the driving end of the lifting drive mechanism is connected with the driving laser welding machine 3, and the lifting drive mechanism can drive the laser welding machine 3 to lift and lower, so as to facilitate the completion of the wiring harness body 6 butt welding; the wire harness dragging mechanism and the heat shrink tube conveying mechanism are both connected with the driving end of the lifting drive mechanism, the wire harness dragging mechanism is used to drag the wire harness body 6, and the heat shrink tube conveying mechanism is used to push the heat shrink tube body 8, and the wire harness body 6 passes through the heat shrink tube body 8. It should be noted that the heat shrink tube body 8 here is an insulating colloid that shrinks when heated, which is a commonly used material in wire harness processing. When the lifting drive mechanism drives the laser welding machine 3 to rise, the exposed metal ends of the two harness bodies 6 have been welded together. At this time, the harness dragging mechanism and the heat shrink tube conveying mechanism move in opposite directions. The harness dragging mechanism drags the welded harness bodies 6 to one side, and the heat shrink tube conveying mechanism pushes the heat shrink tube body 8 on one of the harness bodies 6 to the opposite direction. Finally, the exposed metal ends that are welded together are in the heat shrink tube body 8. The heat shrink tube conveying mechanism includes a heating mechanism for heating the heat shrink tube body 8, so as to facilitate the heat shrink tube body 8 to shrink due to heat, thereby wrapping the exposed metal end of the wiring harness body 6 to achieve insulation wrapping treatment.

[0025] In some specific embodiments, such as Figures 3 to 5 As shown, the heat shrink tube conveying mechanism includes a support rod group, a push piece 20 and a first U-shaped slide 19; the heat shrink tube body 8 is sleeved on the support rod group, and the heat shrink tube body 8 can slide laterally relative to the support rod group. The support seat 1 is fixedly connected to a first support rail 16, and the first support rail 16 is distributed parallel to the support rod group. The first U-shaped slide 19 is slidably connected to the first support rail 16. The push piece 20 is provided with two pieces, and is symmetrically fixed on the first U-shaped slide 19, distributed on the upper and lower sides, and the push piece 20 is used to contact the end of the heat shrink tube body 8 away from the metal exposed body of the wiring harness body 6, and push the heat shrink tube body 8.

[0026] Among them, the support rod group includes a cross bar 26 and a spacing adjustment mechanism. There are multiple cross bars 26, and the multiple cross bars 26 are distributed around one of the wiring harness bodies 6. The heat shrinkable tube body 8 is sleeved on the circumferentially distributed cross bars 26, and is supported by the distributed cross bars 26 to maintain an open state, which is convenient for one of the wiring harness bodies 6 to pass through the heat shrinkable tube body 8 horizontally, and in order to ensure that the heat shrinkable tube body 8 can effectively slide and detach along the cross bars 26, it is necessary to ensure that the surface of the cross bars 26 is smooth, and a lubricant can be coated; the spacing adjustment mechanism is used to adjust the spacing between adjacent cross bars 26, which is convenient for adjustment according to the size of the heat shrinkable tube body 8; and the push sheet 20 is in the form of a thin sheet, and a push sheet 20 can be distributed between two adjacent cross bars 26 without interfering with each other.

[0027] It should be noted that the heat shrinkable tube 8 itself has a certain elasticity to maintain the tubular shape, and the operator can normally put it on the circumferentially distributed cross bars 26.

[0028] The above-mentioned spacing adjustment mechanism includes a support ring 24 and an auxiliary electric telescopic rod 25. The support ring 24 is fixedly arranged on the support seat 1 through a support plate. The central axis of the support ring 24 is parallel to the cross bar 26. There are multiple auxiliary electric telescopic rods 25, which are circumferentially distributed on the inner circle side wall of the support ring 24. The telescopic end of each auxiliary electric telescopic rod 25 is fixedly connected to the cross bar 26, and the telescopic end of each auxiliary electric telescopic rod 25 points to the center of the support ring 24. When it is necessary to adjust the spacing between the distributed cross bars 26, all the auxiliary electric telescopic rods 25 are controlled to telescope synchronously.

[0029] It should be noted that in order to facilitate the stable support of the cross bar 26, a circular plate is fixedly arranged on one side of the support ring 24, and a through-type sliding groove is opened on the circular plate. The cross bar 26 passes through the sliding groove on the circular plate to facilitate relative sliding, and can also rely on the circular plate for positioning. The sliding groove here is set according to the number of cross bars 26. For example, if there are four cross bars 26, the sliding groove is a cross groove.

[0030] In some specific embodiments, in combination Figure 1 and Figure 3 As shown, the wire harness dragging mechanism includes a second U-shaped slide 15 and an elastic clamp for fixing and clamping the wire harness body 6. The second U-shaped slide 15 is slidably connected to the first support rail 16. Compared with the first U-shaped slide 19, the second U-shaped slide 15 is located farther away from the welding support mechanism, and the elastic clamp is arranged on the second U-shaped slide 15.

[0031] Among them, the above-mentioned elastic clamp includes a clamping block 18 and a limit spring 28, and two clamping blocks 18 and limit springs 28 are each provided. The two clamping blocks 18 are symmetrically distributed, and each clamping block 18 is fixedly connected to the second U-shaped slide 15 through the corresponding limit spring 28. The limit spring 28 is compressible, and each clamping block 18 is fixedly connected with a guide rod 27, and the guide rod 27 passes through the side wall of the second U-shaped slide 15. It should be noted that the sliding direction of the guide rod 27 is the same as the extension and contraction direction of the limit spring 28. The two clamping blocks 18 are in contact with each other in the initial state. When it is necessary to process and dock the wiring harness body 6, one of the wiring harness bodies 6 is passed through the two clamping blocks 18. When the two clamping blocks 18 are separated, the limit spring 28 is compressed to generate a rebound force, so that it is convenient to rely on the rebound force of the limit spring 28 to realize that the clamping block 18 clamps the wiring harness body 6 and fixes it, and in order to ensure the clamping and fixing effect, anti-slip teeth can be provided on the clamping surface of the clamping block 18.

[0032] In some specific embodiments, in combination Figure 1 and Figure 2As shown, the lifting drive mechanism includes a main electric telescopic rod 2, a one-way top plate 14 and a linkage lower pressure plate 10. The main electric telescopic rod 2 is fixedly arranged on the support seat 1 through a bracket and is in a vertical position with its telescopic end facing downward. The laser welding machine 3 is fixedly installed on the telescopic end of the main electric telescopic rod 2. One side of the telescopic end of the main electric telescopic rod 2 is fixedly connected with a cross frame 13. The one-way top plate 14 is fixedly arranged at the end of the cross frame 13. The linkage lower pressure plate 10 is arranged above the position between the first U-shaped slide 19 and the second U-shaped slide 15, and both sides of the bottom of the linkage lower pressure plate 10 are movably connected with linkage rods 30 through hinges. The tops of the slide 19 and the second U-shaped slide 15 are movably connected to the corresponding ends of the linkage rod 30 through hinges, and a stretchable return spring is connected between the first U-shaped slide 19 and the second U-shaped slide 15, and the return spring is in the first support guide rail 16; a hanger 12 is provided on one side of the linkage lower pressure plate 10, and the position of the hanger 12 is fixed relative to the support seat 1. The hanger 12 can be directly welded to the bracket supporting the main electric telescopic rod 2, and the bottom of the hanger 12 is rotatably connected to a rotating pressure rod 11 through a rotating shaft, and one end of the rotating pressure rod 11 is fitted on the linkage lower pressure plate 10, and the other end is aligned with the one-way top plate 14.

[0033] Combination Figure 7 and Figure 8 As shown, after the exposed metal ends of the two wiring harness bodies 6 are spliced ​​on the laser welding support mechanism, and the tail end of one of the wiring harness bodies 6 passes through the placed heat shrink tube body 8, and passes through the two clamping blocks 18 to be fixed and clamped, then the main electric telescopic rod 2 is controlled to extend, driving the laser welding machine 3 to be pressed down onto the welding support mechanism, and the exposed metal ends of the two wiring harness bodies 6 spliced ​​together are welded; then the main electric telescopic rod 2 is controlled to shrink, and during this process the one-way top plate 14 rises with the main electric telescopic rod 2. During the rising process, after reaching the corresponding height position, the one-way top plate 14 begins to contact one end of the rotating pressure rod 11 and pushes it upward, and at this time the other end of the rotating pressure rod 11 deflects downward , thereby squeezing the lower pressing plate 10 downward, and during the descent of the linked lower pressing plate 10, the first U-shaped slide 19 and the second U-shaped slide 15 are pushed to slide and separate to both sides through the linkage rods 30 on both sides of the bottom, so that the second U-shaped slide 15 pulls the fixedly clamped wiring harness body 6 through the clamping block 18, so that the metal exposed parts of the two wiring harness bodies 6 welded and butted are moved toward the direction of the heat shrinkable tube body 8. At the same time, the first U-shaped slide 19 pushes the heat shrinkable tube body 8 to move toward the metal exposed position close to the wiring harness body 6 through the push piece 20. When the main electric telescopic rod 2 shrinks and stops, the heat shrinkable tube body 8 just covers the metal exposed parts of the two wiring harness bodies 6, and then heats and shrinks them through the heating mechanism to achieve insulation wrapping.

[0034] In some specific embodiments, the heating mechanism includes a hot air blower 23 and a curved heating plate 9, the hot air blower 23 is fixedly mounted on one side of the support seat 1, and a pressure sensing switch 17 electrically connected to the hot air blower 23 is fixedly mounted on one end of the first support rail 16 away from the welding support mechanism; two curved heating plates 9 are provided, which are fixedly connected to the support seat 1 through a bracket and are located between the support rod group and the welding support mechanism. The spacing between the two curved heating plates 9 is greater than the diameter of the heat shrinkable tube body 8, and an air hole is opened on the curved heating plate 9 which is connected to the air outlet end of the hot air blower 23 through a pipe, and an electric heating wire electrically connected to the pressure sensing switch 17 can also be buried on the side wall of the curved heating plate 9.

[0035] When the heat shrink tube 8 is laterally moved to cover the exposed metal part of the two wiring harness bodies 6, it is just between the two curved heating plates 9, and at this time the second U-shaped slide 15 just hits the pressure sensing switch 17, and the pressure sensing switch 17 starts the hot air blower 23 to deliver hot air to the air holes on the curved heating plate 9, so as to blow hot air to the heat shrink tube 8 to heat and shrink it.

[0036] In some specific embodiments, in combination Figure 2 and Figure 6 As shown, the welding support mechanism includes a second support rail 4 and a support slider 7. The second support rail 4 is fixedly connected to the support seat 1, and the second support rail 4 is perpendicular to the first support rail 16. The support slider 7 is slidably connected to the second support rail 4. The support slider 7 is provided with two pieces and is symmetrically distributed on the second support rail 4. The two support sliders 7 are initially spliced ​​together. The top of the spliced ​​end faces is provided with a positioning groove for locating the exposed metal end of the wiring harness body 6. The two support sliders 7 are each divided into half of the positioning groove. When the two support sliders 7 are spliced ​​together When put together, they are spliced ​​into a complete positioning groove; a screw rod 29 is rotatably arranged inside the second supporting guide rail 4, and the two supporting sliders 7 are threadedly connected to the screw rod 29. It should be noted here that two sections of threads with opposite rotation directions are distributed on the screw rod 29, and the two supporting sliders 7 are respectively connected to the corresponding threads. When the screw rod 29 rotates, the two supporting sliders 7 either move together to dock or separate; one end of the screw rod 29 is coaxially fixedly connected to a gear 22, and a rack 21 is meshed on one side of the gear 22, and the rack 21 is fixedly connected to the linkage lower pressure plate 10 through a connecting frame.

[0037] When the linkage lower pressure plate 10 descends, the linkage lower pressure plate 10 descends together with the rack 21. The rack 21 drives the gear 22 to rotate during the descending process. The gear 22 drives the screw 29 to rotate. The screw 29 causes the two supporting sliders 7 to slide apart along the second supporting guide rail 4 to avoid interfering with the wiring harness dragging mechanism to drag the wiring harness body 6.

[0038] It should be noted that in order to ensure the transmission effect of the screw 29, reduce the rotation resistance, and ensure effective operation, the screw 29 can be designed as a ball screw.

[0039] It should be noted that when the laser welding machine 3 is higher than the welding support mechanism and the one-way top plate 14 is lower than the corresponding end position of the rotating pressure rod 11, the two support sliders 7 are in a state of being spliced ​​together. Therefore, when the wiring harness body 6 needs to be placed again for docking, the main electric telescopic rod 2 can drive the laser welding machine 3 to descend a certain distance without pressing on the support slider 7, and then the wiring harness body 6 is placed, and then controlled to descend for welding and docking.

[0040] In some specific implementation schemes, since two wiring harness bodies 6 are docked, one wiring harness body 6 passes through the position of the heat shrink tube body 8 and is clamped and fixed by the clamp block 18, and is also supported. The other wiring harness body 6 also needs support, so a bracket 5 is fixedly connected to the side of the welding support mechanism away from the wire harness dragging mechanism through a bracket, and the corresponding wiring harness body 6 is placed on the bracket 5.

[0041] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios: First, put the heat shrink tube 8 to be used on the support rod group, then put a wire harness body 6 on the bracket 5, so that the exposed metal part of it is stuck in the positioning groove on the spliced ​​support slider 7, and then also stick the exposed metal part of another wire harness body 6 in the positioning groove, and let the tail end pass through the placed heat shrink tube body 8 and pass it between the two clamping blocks 18 to fix it.

[0042] Then the main electric telescopic rod 2 is controlled to extend, driving the laser welding machine 3 to descend to the two spliced ​​support sliders 7, and the laser welding machine 3 is used to weld the exposed metal ends of the two wiring harness bodies 6; then the main electric telescopic rod 2 is controlled to retract, and during this process, the one-way top plate 14 rises with the main electric telescopic rod 2. During the rising process, after reaching the corresponding height position, the one-way top plate 14 begins to contact one end of the rotating pressure rod 11 and pushes it upward, and at this time, the other end of the rotating pressure rod 11 deflects downward , thereby squeezing the lower pressing plate 10 downward, and during the descent of the linked lower pressing plate 10, the first U-shaped slide 19 and the second U-shaped slide 15 are pushed to both sides through the linkage rods 30 on both sides of the bottom to slide and separate, so that the second U-shaped slide 15 pulls the fixedly clamped wiring harness body 6 through the clamping block 18, so that the metal exposed parts of the two wiring harness bodies 6 welded and connected are moved toward the direction of the heat shrinkable tube body 8, and at the same time, the first U-shaped slide 19 pushes the heat shrinkable tube body 8 to move to the metal exposed position close to the wiring harness body 6 through the pushing piece 20.

[0043] And when the linkage lower pressure plate 10 descends, the linkage lower pressure plate 10 descends with the rack 21. The rack 21 drives the gear 22 to rotate during the descent process, and the gear 22 drives the screw 29 to rotate. The screw 29 causes the two supporting sliders 7 to slide apart along the second supporting guide rail 4 to avoid hindering the dragging of the wiring harness body 6.

[0044] When the main electric telescopic rod 2 shrinks and stops, the heat shrink tube 8 just covers the exposed metal part of the two wiring harness bodies 6, and at this time the heat shrink tube 8 is just between the two curved heating plates 9, and the second U-shaped slide 15 just touches the pressure sensing switch 17, and the pressure sensing switch 17 starts the hot air blower 23 to transport hot air to the air holes on the curved heating plate 9, so as to blow hot air to the heat shrink tube 8 to heat and shrink it, thereby realizing automatic welding and docking of the wiring harness body 6 and insulation wrapping of the heat shrink tube 8.

[0045] When the first U-shaped slide 19 and the second U-shaped slide 15 slide apart, the reset spring connected therebetween stretches to generate a rebound force. In this way, when the one-way top plate 14 is separated from the rotating pressure rod 11 or has no squeezing force on the rotating pressure rod 11, the first U-shaped slide 19 and the second U-shaped slide 15 slide back and reset, and the lower pressure plate 10 is lifted, thereby linking the two supporting sliders 7 to slide back and reset, and reconnect them together, so as to facilitate the docking of the next set of wiring harness bodies 6.

[0046] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
