[0002] In the production of automotive wiring harnesses, home appliance cables, and aviation cables, tape wrapping is required to achieve functions such as insulation protection, wire harness fixation, identification, and abrasion resistance.

[0017] This wire harness tape multi-point synchronous winding device includes a frame 1, a winding module 5, a sliding plate 4, a double-acting cylinder 3, a pneumatic gripper 6, and a long winding assembly 7 (see the instruction manual appendix). Figure 1 , 2 and 3).

[0018] A sliding plate 4 is mounted on the frame 1 via a longitudinal guide rail 2 and a double-acting cylinder 3. During operation, the double-acting cylinder 3 pushes the sliding plate 4 to slide back and forth along the longitudinal guide rail 2 (see the instruction manual appendix). Figure 3 and 7 ).

[0019] Multiple pneumatic grippers 6 are installed at intervals on the sliding plate 4 (see instruction manual). Figure 1 , 5 and 6).

[0020] A transverse guide rail 33 is mounted in the middle of the sliding plate 4; the pneumatic gripper 6 is connected to the transverse guide rail 33 via an adjusting slide 34; a locking screw is mounted on the adjusting slide 34 (see the instruction manual appendix). Figure 5 The purpose of installing the pneumatic gripper 6 via the transverse guide rail 33, the adjusting slide 34, and the locking screw is to allow the installation position of the pneumatic gripper 6 to be adjusted during assembly by adjusting the slide 34 and the locking screw, so that it can be suitable for tape winding of various types of wire harnesses during operation.

[0021] The sliding plate 4 is symmetrically equipped with long winding assemblies 7 at both ends (see the instruction manual). Figure 1 , 2 and 4).

[0022] The long winding assembly 7 includes a hollow shaft motor 35, a quick clamp 37, and a rotating plate 38 (see the instruction manual appendix).Figure 4 , 11 and 12).

[0023] A hollow shaft motor 35 is mounted on the sliding plate 4; a locking plate 40 is fixedly mounted on one side of the hollow shaft motor 35; a quick clamp 37 is mounted on the other side of the hollow shaft motor 35 via a support plate (36); a connecting shaft 41 is fixedly mounted on one end of the support plate 36; the connecting shaft 41 passes through the hollow shaft motor 35 and is fixedly connected to the locking plate 40 via a locking screw 42. The purpose of this arrangement is to keep the quick clamp 37 relatively stationary with respect to the hollow shaft motor 35 via the support plate 36, the connecting shaft 41, and the locking plate 40.

[0024] A rotating plate 38 is provided on one side of the quick clamp 37; the rotating plate 38 is connected to the rotating sleeve of the hollow shaft motor 35 through a connecting rib 39. During operation, the hollow shaft motor 35 can drive the rotating plate 38 to rotate synchronously through the connecting rib 39.

[0025] When the long winding assembly 7 is in operation, the wire harness is placed on the rotating plate 38 and the support plate 36, and then clamped by the quick clamp 37 to ensure that the wire harness remains stationary. A piece of tape is then attached to the rotating plate 38, adhering to the wire harness. The hollow shaft motor 35 then drives the rotating plate 38 to rotate synchronously via the connecting rib 39. During the rotation of the rotating plate 38, the tape rotates along with it, while the wire harness remains stationary under the action of the quick clamp 37. In this way, the rotating tape wraps around the wire harness, completing the winding process.

[0026] Multiple winding modules 5 are mounted on the frame 1 outside the sliding plate 4 (see instruction manual appendix). Figure 2 and 6 An assembly plate 8 is mounted on the frame 1 outside the sliding plate 4; the assembly plate 8 is provided with elongated assembly holes 9; multiple winding modules 5 are installed at intervals within the elongated assembly holes 9. The assembly plate 8 is provided with scale markings (not shown in the attached diagram of the instruction manual). The purpose of installing the winding modules 5 through the elongated assembly holes 9 is to adjust the installation position of the winding modules 5 as needed, so as to make them suitable for various wire harness tape winding applications.

[0027] The winding module 5 includes a transmission mechanism 27, an unwinding roller 11, a tape, a module housing 10, a cutting blade 20, a rotating module 15, and a pressing module 17 (see the attached instruction manual). Figure 8 , 9 and 10).

[0028] A module housing 10 is mounted on the assembly plate 8; one end of the module housing 10 is fitted with a tape roll 12 via an unwinding roller 11. The other end of the module housing 10 has an clearance notch 13; multiple drive rollers 14 are arranged in a ring shape on the module housing 10 inside the clearance notch 13; a semi-circular rotating module 15 is movably mounted inside the drive rollers 14 (see the attached manual). Figure 10 When each drive roller 14 rotates synchronously, it can drive the rotating module 15 to rotate synchronously.

[0029] A clamping module 17 is mounted inside the module housing 10 below the rotating module 15 via a clamping electromagnet 16; a position sensor 18 is mounted below the clamping module 17 (see the attached instruction manual). Figure 10 The position sensor 18 is an externally purchased component, with the manufacturer's model number being Cablex-M TWM-1. During operation, when the position sensor 18 detects the tape, the clamping electromagnet 16 drives the clamping module 17 to clamp the tape.

[0030] A cutting blade 20 is mounted inside the module housing 10 above the rotating module 15 via a cutting electromagnet 19. The cutting blade 20 has an anti-cutting notch (not shown in the attached diagram of the instruction manual). The purpose of the anti-cutting notch is to ensure that when the cutting blade 20 acts on the tape, it can only partially cut the tape under the action of the anti-cutting notch.

[0031] The module housing 10 above the cutting blade 20 contains a tape feeding upper shaft 21; a tape feeding lower shaft 22 is installed below the tape feeding upper shaft 21; multiple tape guide upper rollers 23 are installed on one side of the tape feeding upper shaft 21; multiple tape guide lower rollers 24 are installed on one side of the tape feeding lower shaft 22 (see the instruction manual appendix). Figure 10 When the upper belt feeding shaft 21, the lower belt feeding shaft 22, the upper belt guide roller 23, and the lower belt guide roller 24 are working, they can drive the belt to move backward.

[0032] Small protrusions (not shown in the attached drawings) are provided on the surfaces of the upper belt feed shaft 21, lower belt feed shaft 22, upper belt guide roller 23, and lower belt guide roller 24. These protrusions make point contact with the belt, preventing the belt from wrapping around its surface when the upper belt guide roller 23 rotates. Additionally, guide posts (not shown in the attached drawings) are fixed between the upper belt feed shaft 21, lower belt feed shaft 22, upper belt guide roller 23, and lower belt guide roller 24. These guide posts guide the belt forward, further reducing the risk of the belt sticking to the upper belt feed shaft 21 and upper belt guide roller 23.

[0033] The module housing 10 is equipped with a drive gear 26 via a reduction motor 25; the drive gear 26 is connected to the upper belt feed shaft 21, the lower belt feed shaft 22, and the drive roller 14 via a transmission mechanism 27 (see the attached instruction manual). Figure 8 ).

[0034] Transmission mechanism 27 includes upper transmission gear 28, lower transmission gear 29, intermediate gear A30, intermediate gear B32, and transmission gear 31 (see appendix to the instruction manual). Figure 8 ).

[0035] One end of the upper belt feeding shaft 21 extends to the outside of the module housing 10 and is fitted with an upper drive gear 28; one end of the lower belt feeding shaft 22 extends to the outside of the module housing 10 and is fitted with a lower drive gear 29; the upper drive gear 28 and the lower drive gear 29 are meshed together; the lower drive gear 29 is meshed with the drive gear 26 through an intermediate gear A30 (see the appendix of the instruction manual). Figure 8 When the drive gear 26 rotates, it can drive the upper transmission gear 28 and the lower transmission gear 29 to rotate through the intermediate gear A30; during the rotation of the upper transmission gear 28 and the lower transmission gear 29, they can drive the upper belt feeding shaft 21 and the lower belt feeding shaft 22 to rotate synchronously.

[0036] The upper drive gear 28 is connected to each of the upper belt guide rollers 23 via a drive belt and a pulley; the lower drive gear 29 is connected to each of the lower belt guide rollers 24 via a drive belt and a pulley (not shown in the attached drawings). During rotation, the upper drive gear 28 and the lower drive gear 29 can drive each of the upper belt guide rollers 23 and each of the lower belt guide rollers 24 to rotate via the drive belt and pulley, respectively.

[0037] One end of the drive roller 14 extends to the outside of the module housing 10 and is fitted with a transmission gear 31; adjacent transmission gears 31 are connected by meshing intermediate gears B32; the set of intermediate gears B32 is connected to the drive gear 26 (see the appendix of the specification). Figure 8 When the drive gear 26 rotates, it can drive each transmission gear 31 to rotate through the intermediate gear B32; when the transmission gear 31 rotates, it can drive the drive roller 14 to drive the rotation module 15 to rotate.

[0038] When the multi-point synchronous winding device for wire harness tape is working, the wire harness is first placed on the quick clamp 37 and clamped with the quick clamp 37; then the two ends of the wire harness are placed on the rotating plate 38 and the support plate 36 of the long winding assembly 7, and the wire harness is clamped with the quick clamp 37 to ensure that the wire harness does not move.

[0039] After the wire harness is placed, a piece of tape is attached to the rotating plate 38 and bonded to the wire harness. Then, the hollow shaft motor 35 drives the rotating plate 38 to rotate synchronously via the connecting rib 39. During the rotation of the rotating plate 38, the tape rotates along with it, while the wire harness remains stationary under the action of the quick-clamp 37. The rotating tape then wraps around the wire harness, thus completing the tape wrapping work at both ends of the wire harness.

[0040] When the long winding assembly 7 is working, the winding module 5 drives the tape to move downward through the tape feeding upper shaft 21, tape feeding lower shaft 22, tape guide upper roller 23 and tape guide lower roller 24. When the position sensor 18 senses the tape, the clamping electromagnet 16 can drive the clamping module 17 to clamp the tape. At the same time, the cutting electromagnet 19 drives the cutting knife 20 to move, so that it partially cuts the tape.

[0041] After the above steps are completed, the double-acting cylinder 3 pushes the sliding plate 4 along the longitudinal guide rail 2 toward the winding module 5. When the wire harness touches the adhesive surface of the tape and is brought into the interior of the rotating module 15, the wire harness will pull the tape and tear it at the half-cut position. During this process, since the clamping module 17 is made of Teflon non-stick material, the wire harness will pull the tape and move relative to the clamping module 17. When the position sensor 18 can no longer detect the tape, the clamping module 17 releases the tape, and then the counterclockwise rotating module 15 will drive the tape to wind onto the wire harness.

[0042] After the tape wraps around the wire harness, the double-acting cylinder 3 pushes the sliding plate 4 to reset the wire harness. When the wire harness leaves the winding module 5, the tape at the rear is fed to the position sensor 18. At this time, the cutting knife 20 actuates, partially cutting the tape, while the clamping module 17 clamps the tape. Waiting for the next cycle.

[0043] At this point, the multi-point synchronous winding device for the wire harness tape has completed the multi-point winding work of the wire harness, and a new wire harness can be replaced to enter the next work cycle.

[0044] This wire harness tape multi-point synchronous winding device has a compact structure and ingenious design. After the wire harness is clamped by the pneumatic gripper 6, the winding module 5 can synchronously complete the tape winding work. This solves the problem of difficulty in achieving precise synchronization in existing wire harness tape winding devices, and is particularly suitable for the needs of multi-point winding of wire harness tape.
