Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness processing technology, specifically to a wire cutting device for automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wiring harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments. Body wiring harnesses connect the entire vehicle body and are generally H-shaped.

[0003] Wiring harnesses contain multiple wires. Existing cutting devices cut all wires together, then peel off the rubber from the ends of each wire to expose the metal for connection to terminals. This method is inefficient and affects the overall efficiency of the wiring harness. To address these technical issues, relevant patents have been proposed, such as the Chinese patent with application number 202011052772.1 and publication number CN114309355B, entitled "A Cutting Device for Automotive Electronic Wiring Harnesses." This patent discloses a cutting device for automotive electronic wiring harnesses, including a processing base with an upper top plate fixedly connected to it. The upper top plate has a groove, which is connected to a shearing plate via a linkage device. A cutting blade is connected to the shearing plate via fasteners. A clamping bottom plate is fixedly connected to the processing base, and a clamping upper plate is connected to the processing base via a buffer mechanism. Both the clamping upper plate and the clamping bottom plate have semi-circular limiting grooves, and a heating semi-ring is provided on the inner wall of the semi-circular limiting groove. The invention places the wires in the wire harness one by one into the semi-circular grooves opened on the clamping base plate. Under the action of the lead screw, linkage rod and slider, the shearing plate moves down. Under the action of the L-shaped pressure rod, the clamping upper plate clamps the wires. Then, the wires are cut by the cutting blade set on the shearing plate. Under the action of the support, the heating half ring heats the cut wires, softening the rubber of the wires and making it easier to strip the wire insulation.

[0004] While the aforementioned patent allows heating of the wires in the wire harness, it cannot remove the rubber from the wires. Therefore, the wire harness must be removed from the device first, and then the rubber on each wire end must be detached individually. However, it is known that the rubber on the wire harness ends is only easily detached after being softened by high temperature. If the wire harness is heated before being removed from the device and then placed on another device to unplug the wires, this process wastes a lot of time and can cause the rubber to harden or even completely harden after being heated, making it impossible to remove the rubber from the wire harness ends. This has certain shortcomings. Summary of the Invention

[0010] Furthermore, the pressure-applying component includes a limiting block fixedly connected to the cover plate, a limiting groove is provided on the bearing frame, the limiting block is slidably connected in the limiting groove, and multiple sets of pressure springs are provided between the limiting block and the limiting groove. The elastic force of the pressure springs drives the cover plate to close onto the bearing frame, thereby fixing the wire harness body.

[0011] Furthermore, the transmission mechanism includes a drive rack fixedly connected to the support frame, a spur gear rotatably connected to the frame via a rotating rod, the spur gear meshing with the drive rack; a drive gear is also mounted on the rotating rod, a transmission rack is fixedly connected to the support plate, the transmission rack meshing with the drive gear; and an intermittent connecting member is provided between the drive gear and the rotating rod.

[0012] Furthermore, the intermittent connector includes a connecting rod, which is fixedly connected to the rotating rod, and multiple sets of bases are fixedly connected to the connecting rod. Each base is rotatably connected with a locking tooth, and a torque spring is provided between each locking tooth and the base. The drive gear has a tooth groove on its inner side, and the elastic force of the torque spring drives the locking tooth to engage in the tooth groove.

[0013] Furthermore, both the upper and lower fixing plates are provided with barrier rings in their adapter grooves.

[0014] Furthermore, a handle is fixedly connected to the top of the cover plate for driving the cover plate to slide upward.

Then, a servo cylinder drives the carrier plate to slide downwards. During the downward sliding stroke of the carrier plate, the upper fixing plate slides downwards as well. After the upper fixing plate slides down to the lower fixing plate, it engages with the lower fixing plate to fix the wiring harness body. Then, during the downward sliding stroke of the carrier plate, the cutting blade cuts the wiring harness body. In the process, the carrier plate will trigger the heating unit to turn on via a trigger switch. After the heating unit is turned on, it will heat the wire harness body. After heating for a certain period of time, the servo cylinder will drive the carrier plate to slide upwards, and the stripping component will slide through the transmission mechanism to remove the rubber at the end of the wire harness body. This allows the rubber at the end of the wire harness body to be removed without having to remove the wire harness body from the device and transfer it to an additional device for stripping. Therefore, it can avoid the problem of the rubber cooling down and being unable to strip smoothly, thus improving the working efficiency of the wire cutting device and its practicality, making it suitable for widespread use.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figure 1-13 This invention provides a technical solution: a wire cutting device for automotive wiring harnesses, comprising a frame 1, a support plate 2 vertically slidably connected to the frame 1 via a servo cylinder 3, a cutting blade 7 fixedly connected to the bottom of the support plate 2, and a fixing member for fixing the wiring harness body 9 between the support plate 2 and the frame 1; the fixing member includes a lower fixing plate 5 fixedly connected to the frame 1, and an upper fixing plate 4 fixedly connected to the bottom of the support plate 2, with an adaptation groove 6 between the upper fixing plate 4 and the lower fixing plate 5 adapted to the wiring harness body 9; a heating unit is provided between the frame 1 and the lower fixing plate 5 for heating the wiring harness body 9, and a trigger switch is provided between the support plate 2 and the heating unit; a stripping component is slidably connected to the frame 1, and a transmission mechanism is provided between the stripping component and the support plate 2; during the stroke of the servo cylinder 3 driving the support plate 2 to slide upward, the stripping component is driven to slide through the transmission mechanism, so that the rubber at the end of the wiring harness body 9 is detached.

[0034] Specifically, the automotive wiring harness cutting device includes a frame 1, on which a support plate 2 is vertically slidably connected via a servo cylinder 3. Specifically, adapter blocks are fixedly connected to both sides of the support plate 2, and vertical slots are formed on both sides inside the frame 1. Each adapter block is slidably connected within its corresponding slot to improve the stability of the support plate 2 during sliding. A cutting blade 7 is fixedly connected to the bottom of the support plate 2 for cutting the wiring harness body 9. A fixing member is also provided between the support plate 2 and the frame 1 to secure the wiring harness body 9. Therefore, when using this device, the wiring harness body 9 is placed on the fixing member, and then the servo cylinder 3 drives the support plate 2 to slide downwards. During the downward sliding stroke of the support plate 2, the cutting blade 7 slides downwards, cutting the wiring harness body 9 to meet the operational requirements. Specifically, the fixing components include a lower fixing plate 5 fixedly connected to the frame 1, and an upper fixing plate 4 fixedly connected to the bottom of the support plate 2. An adapter groove 6, adapted to the wire harness body 9, is provided between the upper fixing plate 4 and the lower fixing plate 5. In use, the servo cylinder 3 drives the support plate 2 to slide downwards, and the wire harness body 9 is fixed by the cooperation between the upper fixing plate 4 and the lower fixing plate 5. Simultaneously, a heating unit is provided between the frame 1 and the lower fixing plate 5 to heat the wire harness body 9, heating the rubber at the end of the wire harness body 9 until it melts, facilitating the peeling of the rubber at the end of the wire harness body 9, further improving the working efficiency of the cutting device. A trigger switch is provided between the support plate 2 and the heating unit to control the opening and closing of the heating unit, improving working efficiency. A peeling component is slidably connected to the frame 1, and a transmission mechanism is provided between the peeling component and the support plate 2, facilitating the peeling of the rubber at the upper end of the wire harness body 9, further improving the practicality of the wire cutting device. Specifically, during the stroke in which the servo cylinder 3 drives the carrier plate 2 to slide upward, the stripping component is driven to slide through the transmission mechanism, so that the rubber at the end of the wire harness body 9 is detached.Therefore, during use, the wire harness body 9 is first installed on the frame 1. Then, the servo cylinder 3 drives the support plate 2 to slide downward. During the downward sliding stroke of the support plate 2, the upper fixing plate 4 will also slide downward. After the upper fixing plate 4 slides down to the lower fixing plate 5, it will cooperate with the lower fixing plate 5 to fix the wire harness body 9. Then, during the downward sliding stroke of the support plate 2, the cutting blade 7 will cut the wire harness body 9. During this stroke, the support plate 2 will drive the heating unit to turn on through the trigger switch. After the heating unit is turned on, it will heat the wire harness body 9. After heating for a certain period of time, during the upward sliding stroke of the support plate 2 driven by the servo cylinder 3, the stripping component will slide through the transmission mechanism to make the rubber at the end of the wire harness body 9 fall off. This allows the rubber at the end of the wire harness body 9 to fall off without having to remove the wire harness body 9 from the device and transfer it to an additional device for stripping. Therefore, it can avoid the problem of the rubber not being able to be stripped smoothly due to cooling, improve the working efficiency of the wire cutting device, and also improve the practicality of the wire cutting device, resulting in better performance.

[0035] In the embodiments provided by the present invention, a buffer member 8 is provided between the support plate 2 and the upper fixed plate 4; the buffer member 8 includes a buffer rod 8.1 fixedly connected to the upper fixed plate 4, a buffer groove 8.3 is provided between the support plate 2 and the support plate 2, the buffer rod 8.1 is slidably connected to the support plate 2, and a buffer spring 8.2 is provided between the buffer rod 8.1 and the buffer groove 8.3. Therefore, in actual use, when the servo cylinder 3 drives the support plate 2 to slide downward, the upper fixed plate 4 will slide downward through the support plate 2. After the upper fixed plate 4 slides downward and abuts against the lower fixed plate 5 to fix the wire harness body 9, the cutting blade 7 has not yet reached the predetermined area. At this time, the servo cylinder 3 needs to continue to drive the support plate 2 to slide downward so that the cutting blade 7 can cut the wire harness body 9. At this time, the buffer rod 8.1 will slide inside the buffer groove 8.3 to compress the buffer spring 8.2 and avoid motion interference.

[0036] In the embodiments provided by this invention, the heating unit includes multiple sets of heating wires 12. A mounting groove 11 is provided on the bottom of the lower fixing plate 5, and the multiple sets of heating wires 12 are installed at the bottom of the mounting groove 11 and electrically connected. The trigger switch includes an elastic switch button that controls the heating wires 12 to turn on. A trigger rod is fixedly connected to the support plate 2, and the trigger rod intermittently abuts against the elastic switch button. Therefore, during use, when the servo cylinder 3 drives the support plate 2 to slide downwards, it will cause the trigger rod to slide downwards. After the trigger rod abuts against the elastic switch button, the heating wires 12 will start. Conversely, when the trigger rod does not abut against the elastic switch button, the heating wires 12 will turn off, saving electricity.

[0037] In the embodiments provided by the present invention, the stripping component includes a support frame 13 slidably connected to the frame 1, a cover plate 14 slidably connected vertically to the support frame 13, a fastening groove adapted to the wire harness body 9 is provided between the support frame 13 and the cover plate 14; and a pressure-applying component is also provided between the cover plate 14 and the support frame 13 to improve the stability of the wire harness body 9 during installation.

[0038] In the embodiments provided by the present invention, the pressure-applying component includes a limiting block 16 fixedly connected to the cover plate 14, a limiting groove 17 is formed on the bearing frame 13, the limiting block 16 is slidably connected in the limiting groove 17, and multiple sets of pressure springs 18 are provided between the limiting block 16 and the limiting groove 17. The elastic force of the pressure springs 18 drives the cover plate 14 to cover the bearing frame 13, fixing the wire harness body 9 and further improving the stability of the wire harness body 9 during installation. When the wire harness body 9 is fixed by the pressure-applying component and the cover plate 14, the sliding of the bearing frame 13 will cause the wire harness body 9 to slide.

[0039] In the embodiments provided by the present invention, the transmission mechanism includes a drive rack 19 fixedly connected to the support frame 13, a spur gear 20 rotatably connected to the frame 1 via a rotating rod, the spur gear 20 meshing with the drive rack 19; a drive gear 21 is also mounted on the rotating rod, a transmission rack 27 is fixedly connected to the support plate 2, the transmission rack 27 meshing with the drive gear 21; and an intermittent connecting member is provided between the drive gear 21 and the rotating rod. Therefore, during use, when the servo cylinder 3 drives the support plate 2 to slide upwards, it will drive the transmission rack 27 to slide upwards. The transmission rack 27 drives the drive gear 21 to rotate, which in turn drives the rotating rod to rotate through the intermittent connecting member. When the rotating rod rotates, it drives the spur gear 20 to rotate. When the spur gear 20 rotates, it drives the drive rack 19 to slide. The drive rack 19 then drives the support frame 13 to slide. Since the pressure member covers the cover plate 14 on the support frame 13, the wire harness body 9 can be fixed. At this moment, when the support frame 13 slides, it will drive the wire harness body 9 to slide, which meets the working requirements. At this moment, when the servo cylinder 3 drives the support plate 2 to slide upwards, the support frame 13 will slide immediately, while the upper fixed plate 4 is still restricted by the buffer spring 8.2 and cannot slide. At this moment, it is more convenient for the stripping member to drive the wire harness body 9 to slide, which can greatly improve the stripping efficiency of the entire wire harness body 9. It is suitable for widespread use and meets the needs of social work.

[0040] In the embodiments provided by the present invention, the intermittent connector includes a connecting rod 22, which is fixedly connected to a rotating rod. Multiple sets of bases 23 are fixedly connected to the connecting rod 22. Each base 23 is rotatably connected to a locking tooth 24, and a torque spring is provided between each locking tooth 24 and the base 23. A tooth groove 25 is formed on the inner side of the drive gear 21, and the elastic force of the torque spring causes the locking tooth 24 to engage within the tooth groove 25. Specifically, when the bearing plate 2 slides downwards, the transmission rack 27 drives the drive gear 21 to rotate. At this moment, the locking tooth 24 is compressed and therefore does not drive the connecting rod 22 to rotate. When the support plate 2 slides upward, the locking teeth 24 will engage in the tooth groove 25, which will drive the connecting rod 22 to rotate through the drive gear 21, which in turn will drive the spur gear 20 to rotate. When the spur gear 20 rotates, it will drive the drive rack 19 to slide, which will drive the support frame 13 to slide. Since the pressure member covers the cover plate 14 on the support frame 13, the wire harness body 9 can be fixed. When the support frame 13 slides, it will drive the wire harness body 9 to slide, which meets the working requirements.

[0041] In the embodiments provided by the present invention, a barrier ring 10 is provided in the adapter groove 6 on both the upper fixing plate 4 and the lower fixing plate 5. This can further improve the peeling efficiency.

[0042] In the embodiments provided by the present invention, a handle 15 is fixedly connected to the top of the cover plate 14 for driving the cover plate 14 to slide upward, so as to facilitate the removal of the stripped wire harness body 9.

[0043] In the embodiments provided by the present invention, the bottom of the frame 1 is provided with multiple sets of support legs, which further improves the stability of the entire tangent device during operation, and each support leg is also provided with an anti-slip pad at the bottom, which provides better anti-slip effect.

[0044] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
