Description

Technical Field

[0001] This application relates to the field of wire storage equipment technology, and in particular to a wire storage machine for wire harness processing. Background Technology

[0002] Active wire feeding with a wire storage mechanism is a common method for feeding wire and cable harnesses. During the production and processing of the harness, a wire storage machine is needed to wind the harness onto a wire storage reel for later feeding. Existing wire storage machines mainly consist of a wire storage reel and a cantilevered combination guide wheel. The combination guide wheel has a conductor, and the wire storage reel rotates to feed the wire. Depending on the tension of the harness and the diameter of the wire, the cantilever moves up and down, which is linked to a frequency converter controlled by a displacement potentiometer. This allows the feeding speed to be linked to the traction speed or the feeding speed, and the wire does not become tangled when the machine stops.

[0003] However, existing wire storage machines require stopping the machine after the wire storage reel is finished winding and then replacing the reel. In the mass production and processing of wire harnesses, frequent shutdowns reduce the processing efficiency and result in low economic benefits. Therefore, a wire storage machine for wire harness processing is provided to wind wire harnesses without stopping the machine or reducing the frequency. Summary of the Invention

[0004] This application proposes a wire storage machine for wire harness processing, which has the advantages of storing wires without stopping the machine or reducing the frequency, thereby solving the problem of frequent machine shutdowns for replacing the wire storage reel in existing equipment.

[0005] To achieve the above objectives, this application adopts the following technical solution: a wire storage machine for wire harness processing, comprising a frame consisting of a base plate and a support plate, and a wire storage reel. A disc is provided on one side of the frame, and a second motor for driving the disc to rotate is provided on the frame. The wire storage reel is movably mounted on the side of the disc. A first motor for driving the wire storage reel to rotate is provided on the frame. Six spare winding mechanisms are provided on the side of the disc outside the wire storage reel, and the six spare winding mechanisms are arranged in a circumferential array on the disc. A wire guide mechanism is provided on the side of the disc inside the spare winding mechanisms, and the wire guide mechanism is located outside the wire storage reel. One end of the wire harness is wound around the six spare winding mechanisms and fixedly connected to the wire storage reel via the wire guide mechanism. During the replacement of the wire storage reel, the disc drives the six spare winding mechanisms to rotate and temporarily wind the wire.

The output shaft of the first motor is fixedly connected to one end of the first rotating shaft, and the other end of the first rotating shaft extends to the outer side of the positioning ring plate and is movably sleeved with the wire storage reel. A positioning ring plate is fixedly connected to the side of the disc away from the toothed ring, and a rotating ring plate is fixedly fitted to the outer side of the positioning ring plate through a bearing. Four insert shafts are fixedly connected to the side of the rotating ring plate away from the disc, and the four insert shafts are movably engaged with one side of the wire storage reel.

[0007] Furthermore, a gear ring is fixedly connected to the side of the disc facing the support plate, the second motor is fixedly installed on the outside of the support plate, and the output shaft of the second motor is fixedly connected to a second rotating shaft. A gear is fixedly fitted at one end of the second rotating shaft, and the outer edge of the gear meshes with the outer edge of the gear ring.

[0008] Furthermore, a positioning block is fixedly installed on the outer edge of the inner side of the disk. There are six positioning blocks, and each of the spare winding mechanisms is fixedly installed on one side of each positioning block.

[0009] Furthermore, the spare winding mechanism includes a guide roller, a limiting shaft is movably mounted in the middle of the guide roller, and one end of the limiting shaft is fixedly connected to the side of the positioning block. A partition is fixedly connected to the side of the guide roller away from the positioning block. A positioning horizontal plate is fixedly connected to the top of the end of the limiting shaft away from the positioning block. A positioning vertical plate is fixedly connected to the top of the positioning horizontal plate. A groove is provided on the positioning vertical plate. A limiting horizontal shaft is movably mounted in the groove. A limiting roller located above the guide roller is movably mounted on the limiting horizontal shaft. A baffle located on one side of the limiting roller is fixedly mounted on the limiting horizontal shaft. The side of the baffle is movably connected to the side of the positioning vertical plate. A nut is threaded onto one end of the limiting horizontal shaft.

[0010] Furthermore, the outer diameter of the guide roller decreases uniformly from the end near the positioning block to the end away from the positioning block, and the outer side of the limiting roller is adapted to the outer side of the guide roller. A gap is reserved between the end of the limiting roller away from the positioning vertical plate and the positioning block for the wire harness to pass through.

[0011] Furthermore, a wire-leveling mechanism is fixedly installed on the side of the disc. The wire-leveling mechanism includes a transverse support plate fixedly connected to the side of the disc. The transverse support plate is located inside the spare winding mechanism. A longitudinal support plate is fixedly connected to the top of the wire-leveling mechanism at the end away from the disc. A lead screw is movably fitted between the longitudinal support plate and the disc. A third motor is fixedly installed on the side of the disc. The output shaft of the third motor is fixedly connected to one end of the lead screw. Two limiting shafts are fixedly connected between the longitudinal support plate and the disc, and the two limiting shafts are respectively located on both sides of the lead screw. Two sliding plates are threaded onto the lead screw. The bottom of the sliding plates is movably connected to the top of the transverse support plate. The sliding plates are movably fitted with the two limiting shafts.

[0012] Furthermore, a sliding shaft located above the lead screw is fixedly connected between the longitudinal support plate and the disc. The sliding shaft is movably sleeved with two sliding plates, and a wire guide mechanism located between the two sliding plates is movably sleeved on the sliding shaft. The wire guide mechanism includes a limiting disc, the sides of which are fixedly connected to the inner sidewalls of the two sliding plates respectively.

[0013] This application provides a wire storage machine for wire harness processing. It features six circumferentially arrayed spare winding mechanisms and a conductor mechanism on the outside of the storage reel. The wire harness is wound around the spare winding mechanisms and conductor mechanism before being connected to the storage reel for winding. The conductor mechanism ensures the wire harness is evenly wound onto the storage reel. Furthermore, when changing the storage reel, the six spare winding mechanisms rotate to wind the wire, with a radius much larger than that of the wire feeding guide wheel. This allows for continuous wire harness winding without downsizing or frequency reduction while maintaining a constant rotation speed of the wire feeding guide wheel, improving storage efficiency and ensuring the wire harness remains taut, thus enhancing subsequent winding performance. The slow rotation of the reel allows the six spare winding mechanisms to wind sufficiently long wire harnesses, providing operators with ample time to change the storage reel.

A second motor 13 is provided on the outer side of the support plate 2. The output shaft of the second motor 13 passes through the support plate 2 and is fixedly connected to a second rotating shaft 14. A gear 15 is fixedly sleeved on one end of the second rotating shaft 14. A gear ring 12 meshes with the outer edge of the gear 15. A disc 3 is fixedly connected to the side of the gear ring 12. The second rotating shaft 14 driven by the second motor 13 drives the gear 15 to rotate, thereby driving the disc 3 to rotate. A positioning ring plate 301 is fixedly connected to the side of the disc 3 away from the gear ring 12. A rotating ring plate 302 is fixedly sleeved on the outer side of the positioning ring plate 301 through a bearing. Four insert shafts 22 are fixedly connected to the side of the rotating ring plate 302 away from the disc 3. The four insert shafts 22 are movably engaged with one side of the wire storage reel 4. Two support rollers 9 supporting the disc 3 are provided on the top of the base plate 1.

[0019] The first rotating shaft 10 is movably mounted in the middle of the support plate 2. The first motor 11 is fixedly installed on the outer side of the support plate 2. The output shaft of the first motor 11 is fixedly connected to one end of the first rotating shaft 10. The other end of the first rotating shaft 10 extends to the outer side of the positioning ring plate 301 and is movably sleeved with the wire storage reel 4. The wire storage reel 4 can be pulled out from the other end of the first rotating shaft 10, and the wire storage reel 4 rotates together with the first rotating shaft 10 to wind the wire.

[0020] Positioning blocks 5 are fixedly installed on the outer edge of the inner side of the disk 3. There are six positioning blocks 5, and the six positioning blocks 5 are arranged in a circumferential array on the disk 3. A spare winding mechanism 6 is fixedly installed on the side of each positioning block 5 away from the disk 3. Please refer to [link / reference]. Figures 4-5 The spare winding mechanism 6 includes a guide roller 601. A limiting shaft 602 is movably mounted in the middle of the guide roller 601, and one end of the limiting shaft 602 is fixedly connected to the side of the positioning block 5. A partition plate 603 is fixedly connected to the side of the guide roller 601 away from the positioning block 5. A positioning horizontal plate 17 is fixedly connected to the top of the end of the limiting shaft 602 away from the positioning block 5. A positioning vertical plate 18 is fixedly connected to the top of the positioning horizontal plate 17. A groove 181 is provided on the positioning vertical plate 18. A limiting horizontal shaft 19 is movably mounted in the groove 181. A movably mounted limit horizontal shaft 19 is mounted on the limiting horizontal shaft 19.

The side of the baffle 21 is movably connected to the side of the positioning vertical plate 18. A nut is threaded onto one end of the limiting horizontal shaft 19. By rotating the nut, the limiting horizontal shaft 19 can be kept horizontally stable in conjunction with the baffle 21. The distance between the outer side of the limiting roller 20 and the outer side of the guide roller 601 can be adjusted according to the outer diameter of the wire harness, so as to ensure that the wire harness passing through the guide roller 601 can be laid flat between the guide roller 601 and the limiting roller 20.

[0021] The outer diameter of the guide roller 601 decreases uniformly from the end near the positioning block 5 to the end away from the positioning block 5. The outer side of the limiting roller 20 is adapted to the outer side of the guide roller 601. A gap is reserved between the end of the limiting roller 20 away from the positioning vertical plate 18 and the positioning block 5 for the wire harness to pass through. By using the inclined surface of the limiting roller 20 to adapt to the guide roller 601, the wire harness always slides towards the end with the smaller outer diameter after passing through the guide roller 601. The side of the positioning block 5 facing the limiting roller 20 is fixedly connected to the guide block 501, and the side of the guide block 501 facing the limiting roller 20 is designed with an inclined surface to facilitate the wire harness to be smoothly wound onto the guide roller 601.

[0022] Please continue reading. Figure 2 , Figure 3 and Figure 6 A wire-leveling mechanism 7 is fixedly installed on the side of the disc 3. The wire-leveling mechanism 7 includes a transverse support plate 701 fixedly connected to the side of the disc 3. The transverse support plate 701 is located inside the spare winding mechanism 6. A longitudinal support plate 702 is fixedly connected to the top of the end of the wire-leveling mechanism 7 away from the disc 3. A lead screw 703 is movably fitted between the longitudinal support plate 702 and the disc 3. A third motor 16 is fixedly installed on the side of the disc 3. The output shaft of the third motor 16 is fixedly connected to one end of the lead screw 703. Two limiting shafts 705 are fixedly connected between the longitudinal support plate 702 and the disc 3. The two limiting shafts 705 are respectively located on both sides of the lead screw 703. Two sliding plates 704 are threaded onto the lead screw 703. The bottom of the sliding plate 704 is movably connected to the top of the transverse support plate 701. The sliding plate 704 is movably fitted with the two limiting shafts 705. The third motor 16 on the disc 3 drives the lead screw 703 to rotate, thereby controlling the sliding plate 704 to move along the lead screw 703.

[0023] A sliding shaft 23 located above the lead screw 703 is fixedly connected between the longitudinal support plate 702 and the disc 3. The sliding shaft 23 is movably sleeved with two sliding plates 704, and a wire guide mechanism 8 located between the two sliding plates 704 is movably sleeved on the sliding shaft 23. The wire guide mechanism 8 includes a limiting disc 804. The sides of the two limiting discs 804 are fixedly connected to the inner sidewalls of the two sliding plates 704 respectively. A sliding sleeve 803 is movably connected between the two limiting discs 804, and the sliding sleeve 803 is movably sleeved with the sliding shaft 23. A positioning guide wheel 801 is fixedly sleeved on the sliding sleeve 803. A moving guide wheel 802 located on one side of the positioning guide wheel 801 is movably sleeved on the sliding sleeve 803. A cylinder 805 is fixedly installed on the outer side of one of the limiting discs 804. A top cap is movably sleeved on the piston shaft of the cylinder 805. The side of the top cap away from the cylinder 805 is fixedly connected to the side of the moving guide wheel 802.

[0024] Please see Figures 2-3The top of the support plate 2 is provided with a wire feeding guide wheel located above the spare winding mechanism 6, and the wire feeding guide wheel is located directly above the gap between the limiting roller 20 and the wire block 501. The wire bundle is wound around six wire rollers 601, and from one of the wire rollers 601 it is wound around the wire mechanism 8, and finally wound onto the wire storage reel 4 by the wire mechanism 8.

[0025] In use, the wire storage machine for wire harness processing operates by a first motor 11 driving a first rotating shaft 10 to rotate a wire storage reel 4. The wire storage reel 4 winds the wire harness, and a third motor 16 drives a lead screw 703 to rotate, controlling two sliding plates 704 to move the moving guide wheel 802 and the positioning guide wheel 801 back and forth along the sliding shaft 23. This ensures that the wire harness is evenly wound onto the wire storage reel 4, guaranteeing the quality of wire storage using the reel 4. Furthermore, when the wire storage reel 4 is full, the wire conductor mechanism 8 moves to the outside of the wire storage reel 4. Cylinder 805 drives the piston shaft to move the movable guide wheel 802 toward the positioning guide wheel 801, clamping the wire harness with the positioning guide wheel 801. At the same time, the first motor 11 stops driving the wire storage reel 4 to rotate, and the second motor 13 drives the second rotating shaft 14 to drive the gear 15 to rotate. The gear 15 drives the gear ring 12 and the disk 3 to rotate as a whole, so that the wire rollers 601 on the six spare winding mechanisms 6 rotate around the central axis of the disk 3. The wire harness fed in by the wire feeding guide wheel is wound on the wire roller 601 and is limited by the limiting roller 20. The wire is laid flat between the limiting roller 20 and the guide roller 601. At this time, the rotation radius of the six spare winding mechanisms 6 is much larger than the rotation radius of the wire feeding guide wheel. Therefore, when the rotation speed of the wire feeding guide wheel is constant, the overall rotation of the disc 3 is slow. The operator can cut the wire bundle between the guide mechanism 8 and the wire storage disc 4, thereby pulling out the wire storage disc 4 from one side and reinstalling the new wire storage disc 4 without the wire bundle. The wire storage disc 4 is then engaged with the insertion shaft 22 on the rotating ring plate 302 to load the wire bundle onto the guide mechanism 8. One end is fixed to the wire storage reel 4. The first motor 11 restarts and drives the first rotating shaft 10 to rotate the wire storage reel 4. At the same time, the second motor 13 stops driving the disc 3 to rotate. Initially, the first motor 11 drives the wire storage reel 4 to rotate faster than the wire feeding guide wheel, so as to quickly wind up the wire bundle wound on the spare winding mechanism 6. Thus, when the wire storage reel 4 is replaced next time, the spare winding mechanism 6 can rewind the wire bundle using the spare winding mechanism 6, thereby achieving the wire bundle winding effect without stopping the machine or reducing the frequency, and improving the wire storage efficiency.
