Abstract

This application discloses an automatic threading device for seat handles, relating to the field of threading equipment. It includes a base with a conveying assembly for feeding wire harnesses. The conveying assembly includes an L-shaped fixing plate fixedly connected to the upper surface of the base. This application utilizes the cooperation between a first rotating shaft, a second rotating shaft, and gears. In use, the wire harness is passed between two guide wheels, inserting one end of the harness into the seat handle. The U-shaped fixing plate is then pushed closer to the L-shaped fixing plate, causing the two guide wheels to clamp the wire harness. Simultaneously, the two gears mesh. Starting the drive motor rotates the first rotating shaft, causing the two gears to rotate relative to each other, which in turn causes the second rotating shaft to rotate in the opposite direction, resulting in both guide wheels rotating simultaneously to feed and thread the wire harness. This design minimizes the problem of increased equipment costs caused by the inability to simultaneously drive both feed wheels with a single motor.

Description

Technical Field

[0001] This application relates to the field of threading equipment, and in particular to automatic threading equipment for chair handles. Background Technology

[0002] Automatic threading equipment is a mechatronic device used to automatically thread cables, wires, etc. through holes or channels in equipment. It is widely used in fields such as communications, power, and construction. In the automobile manufacturing process, automatic threading equipment is needed to thread seat handles.

[0003] Utility model patent CN216287772U discloses an automatic threading device, including a thread feeder and at least one corrugated tube holder arranged sequentially. The thread feeder includes an upper thread feeder and a lower thread feeder arranged vertically and with parallel axes. The upper thread feeder and the lower thread feeder are provided with thread feed grooves to accommodate the wire bundle at circumferentially opposite positions. The corrugated tube holder is provided with a through groove to accommodate the corrugated tube, and the axis of the thread feed groove coincides with the axis of the through groove.

[0004] The aforementioned automatic threading device requires an upper linear motor and a lower linear motor to drive the upper and lower thread feeding wheels respectively when conveying the wire harness. It cannot drive the two upper thread feeding wheels simultaneously with a single motor, which increases the equipment cost. Utility Model Content

[0005] To address the aforementioned issues, this application provides an automatic threading device for seat handles.

[0006] The automatic threading device for chair handles provided in this application adopts the following technical solution:

[0007] An automatic threading device for seat handles includes a base with a conveying assembly for conveying wire harnesses. The conveying assembly includes an L-shaped fixing plate fixedly connected to the upper surface of the base. A drive motor is mounted on the lower surface of the base. A first rotating shaft is fixedly connected to the output end of the drive motor. The end of the first rotating shaft away from the drive motor passes through the base and is rotatably connected to the lower surface of the L-shaped fixing plate. A U-shaped fixing plate is provided on one side of the L-shaped fixing plate on the upper surface of the base. A pushing assembly for moving the U-shaped fixing plate is provided on the base. A second rotating shaft is rotatably connected inside the U-shaped fixing plate. Parallel guide wheels are fixedly connected to both the first and second rotating shafts. Parallel gears are fixedly connected to both the first and second rotating shafts below the guide wheels, and the two gears mesh with each other.

[0008] By adopting the above technical solution, during use, the U-shaped fixing plate is moved away from the L-shaped fixing plate by pushing the component, causing the two guide wheels to separate. Then, the wire harness is passed between the two guide wheels, and one end of the wire harness is inserted into the seat handle. Then, the U-shaped fixing plate is moved closer to the L-shaped fixing plate by pushing the component, causing the two guide wheels to clamp the wire harness. At the same time, the two gears mesh with each other. By starting the drive motor, the first rotating shaft is rotated, causing the two gears to rotate relative to each other, which in turn causes the second rotating shaft to rotate in the opposite direction, causing the two guide wheels to rotate simultaneously to feed and thread the wire harness. This avoids the problem of increasing equipment costs due to the inability to drive the two wire feeding wheels simultaneously with a single motor.

[0009] Preferably, the pushing assembly includes a first support plate fixedly connected to the upper surface of the base. The first support plate is located on the side of the U-shaped fixed plate away from the L-shaped fixed plate. A first cylinder is fixedly connected to one side wall of the first support plate. The output end of the first cylinder passes through the first support plate and is fixedly connected to the U-shaped fixed plate.

[0010] By adopting the above technical solution, the first cylinder is activated to move the U-shaped fixing plate and adjust the distance between the U-shaped fixing plate and the L-shaped fixing plate, making it easier to place the wire harness between the two wire pulleys.

[0011] Preferably, a wire feeding box is fixedly connected to one side of the upper surface of the base between the two wire guide wheels, and a support base is fixedly connected between the wire feeding box and the wire guide wheels. A wire groove is formed on the upper surface of the support base.

[0012] By adopting the above technical solution, multiple wire harnesses can be conveniently stored in the wire delivery box. When the wire harness is passed between two guide wheels, it is made to sink into the guide groove, which can improve the stability of the wire harness during transportation and prevent the wire harness from swinging.

[0013] Preferably, a support platform is fixedly connected to the side of the upper surface of the base away from the cable box. A T-shaped placement groove for placing the seat handle is opened on the upper surface of the support platform. One end of the T-shaped placement groove is close to the guide wheel. A second support plate is fixedly connected to the upper surface of the base. A second cylinder is fixedly connected to one side wall of the second support plate. The output end of the second cylinder passes through the second support plate and is fixedly connected to an arc-shaped push plate. The arc-shaped push plate is slidably disposed in the T-shaped placement groove.

[0014] By adopting the above technical solution, the seat handle is placed in the T-shaped placement slot, with one end of the seat handle close to the guide wheel. One end of the wire harness is inserted into the seat handle. Then, by activating the second cylinder, the arc-shaped push plate is pushed to move in the T-shaped placement slot, so that the arc-shaped push plate abuts against the seat handle, fixing the seat handle in the T-shaped placement slot, making it convenient to pass the wire harness through the seat handle.

[0015] Preferably, a plurality of guide rods are provided between the first support plate and the U-shaped fixing plate. One end of the guide rod is fixedly connected to the U-shaped fixing plate, and the other end of the guide rod passes through the first support plate and forms a sliding arrangement.

[0016] By adopting the above technical solution, the stability of the U-shaped fixed plate during movement can be improved by using the guide rod, preventing the U-shaped fixed plate from shaking and making it difficult for the two gears to mesh.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application utilizes the cooperative arrangement of a first rotating shaft, a second rotating shaft, and gears. In use, by pushing the component, the U-shaped fixing plate is moved away from the L-shaped fixing plate, causing the two guide wheels to separate. The wire harness is then passed between the two guide wheels, with one end inserted into the seat handle. The component is then pushed to bring the U-shaped fixing plate closer to the L-shaped fixing plate, causing the two guide wheels to clamp the wire harness. Simultaneously, the two gears mesh with each other. By starting the drive motor, the first rotating shaft rotates, causing the two gears to rotate relative to each other, which in turn causes the second rotating shaft to rotate in the opposite direction, making the two guide wheels rotate simultaneously to feed and thread the wire harness. This design minimizes the problem of increased equipment costs caused by the inability to drive both feed wheels simultaneously with a single motor.

[0019] 2. The wire delivery box facilitates the storage of multiple wire harnesses. When the wire harness is passed between two guide rollers, it is embedded in the guide groove, which can improve the stability of the wire harness during delivery and prevent the wire harness from swinging.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses an automatic threading device for seat handles.

[0027] Reference Figure 1 , Figure 2 and Figure 3 Automatic wire threading device for seat handles includes a base 1, on which a conveying assembly for conveying wire harnesses is provided. The conveying assembly includes an L-shaped fixing plate 2, a drive motor 3, a first rotating shaft 4, a U-shaped fixing plate 5, a second rotating shaft 6, a guide wheel 7, and a gear 8.

[0028] The L-shaped fixing plate 2 is fixedly connected to the upper surface of the base 1. The drive motor 3 is installed on the lower surface of the base 1. One end of the first rotating shaft 4 is fixedly connected to the output end of the drive motor 3. The end of the first rotating shaft 4 away from the drive motor 3 passes through the base 1 and is rotatably connected to the lower surface of the L-shaped fixing plate 2. The U-shaped fixing plate 5 is set on the upper surface of the base 1 and located on one side of the L-shaped fixing plate 2. The base 1 is provided with a pushing assembly for moving the U-shaped fixing plate 5. The second rotating shaft 6 is rotatably connected inside the U-shaped fixing plate 5. Two guide wheels 7 are provided, which are fixedly connected to the first rotating shaft 4 and the second rotating shaft 6 respectively and are arranged in parallel. Two gears 8 are provided, which are fixedly connected to the first rotating shaft 4 and the second rotating shaft 6 respectively and are located below the guide wheels 7. The two gears 8 mesh with each other.

[0029] Reference Figure 1 and Figure 2 The pushing component includes a first support plate 9 fixedly connected to the upper surface of the base 1. The first support plate 9 is located on the side of the U-shaped fixed plate 5 away from the L-shaped fixed plate 2. A first cylinder 10 is fixedly connected to one side wall of the first support plate 9. The output end of the first cylinder 10 passes through the first support plate 9 and is fixedly connected to the U-shaped fixed plate 5. By activating the first cylinder 10, the U-shaped fixed plate 5 is moved to adjust the distance between the U-shaped fixed plate 5 and the L-shaped fixed plate 2, so as to facilitate the placement of the wire harness between the two wire pulleys 7.

[0030] Reference Figure 1 and Figure 3A wire feeding box 11 is fixedly connected to one side of the upper surface of the base 1 between the two guide wheels 7. A support base 12 is fixedly connected between the wire feeding box 11 and the guide wheels 7. A wire groove 13 is opened on the upper surface of the support base 12. Multiple wire bundles can be conveniently stored through the wire feeding box 11. When the wire bundle is passed between the two guide wheels 7, the wire bundle is inserted into the wire groove 13, which can improve the stability of the wire bundle during transportation and prevent the wire bundle from swinging.

[0031] Reference Figure 1 and Figure 4 A support platform 14 is fixedly connected to the upper surface of the base 1 on the side away from the cable box 11. A T-shaped placement groove 15 for placing the seat handle is opened on the upper surface of the support platform 14. One end of the T-shaped placement groove 15 is close to the guide wheel 7. A second support plate 16 is fixedly connected to the upper surface of the base 1. A second cylinder 17 is fixedly connected to one side wall of the second support plate 16. The output end of the second cylinder 17 passes through the second support plate 16 and is fixedly connected to an arc-shaped push plate 18. The arc-shaped push plate 18 is slidably disposed in the T-shaped placement groove 15. By placing the seat handle in the T-shaped placement groove 15, so that one end of the seat handle is close to the guide wheel 7, and inserting one end of the wire harness into the seat handle, the second cylinder 17 is activated to push the arc-shaped push plate 18 to move in the T-shaped placement groove 15, so that the arc-shaped push plate 18 abuts against the seat handle, and the seat handle is fixed in the T-shaped placement groove 15, making it convenient to pass the wire harness through the seat handle.

[0032] Reference Figure 1 and Figure 2 Multiple guide rods 19 are provided between the first support plate 9 and the U-shaped fixed plate 5. One end of the guide rod 19 is fixedly connected to the U-shaped fixed plate 5, and the other end of the guide rod 19 passes through the first support plate 9 and forms a sliding arrangement. The guide rod 19 can improve the stability of the U-shaped fixed plate 5 when it moves, prevent the U-shaped fixed plate 5 from shaking, and make it difficult for the two gears 8 to mesh with each other.

[0033] The implementation principle of the automatic wiring device for seat handles in this embodiment is as follows: In use, the wire harness is first placed into the wiring box 11. The first cylinder 10 is activated, moving the U-shaped fixing plate 5 away from the L-shaped fixing plate 2. The distance between the U-shaped fixing plate 5 and the L-shaped fixing plate 2 is adjusted. Simultaneously, the seat handle is placed in the T-shaped placement slot 15, with one end of the handle close to the guide wheel 7. Then, the second cylinder 17 is activated, pushing the arc-shaped push plate 18 within the T-shaped placement slot 15, causing the arc-shaped push plate 18 to contact the seat handle and fix the seat handle in the T-shaped slot. The wire harness is placed in the slot 15, and then passed between the two guide wheels 7, so that one end of the wire harness is inserted into the seat handle. Then, the first cylinder 10 is activated to bring the U-shaped fixing plate 5 close to the L-shaped fixing plate 2, so that the two guide wheels 7 clamp the wire harness. At the same time, the two gears 8 mesh with each other. By starting the drive motor 3, the first rotating shaft 4 is driven to rotate, so that the two gears 8 rotate with each other, driving the second rotating shaft 6 to rotate in the opposite direction, so that the two guide wheels 7 rotate at the same time, and the wire harness is fed and threaded. This avoids the problem that it is impossible to drive the two wire feeding wheels at the same time with a single motor, which would increase the equipment cost.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
