Description

Technical Field

[0001] This invention relates to the field of wire harness production technology, specifically a wire harness coating device with automatic cutting function. Background Technology

[0002] In the automotive and electronic equipment industries, wire harnesses are core components for signal transmission and power supply. They need to be coated with adhesive to achieve insulation, abrasion resistance, waterproofing, and fixed integration functions. Typically, to adapt to some complex environments, a tape wrapping process is used. This process produces wire harnesses that are relatively intact and highly adaptable, without affecting the lifespan or performance of the wire harness, and improves the integrity of the wire harness. At the same time, tape wrapping is one of the most common processing methods.

[0003] Currently, the processing method usually involves manual tape wrapping. This method results in inconsistent wrapping tension, significant variations in quality, and poor overall quality. Furthermore, manual wrapping is time-consuming, labor-intensive, and consumes a large amount of manpower. However, the flexibility of manual labor is difficult to replace in modern processes. Therefore, the need for equipment to perform neat and uniform tape wrapping of wire harnesses is urgent, in order to drive progress in the industrial sector. Summary of the Invention

[0004] The purpose of this invention is to provide a wire harness wrapping device with automatic cutting function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The wire harness coating device includes a coating bed and a cable routing frame. The cable routing frame is slidably connected to the coating bed. The cable routing frame is provided with cable transmission holes. During coating, the wire harness is first passed through the cable transmission holes. The coating bed is also provided with a cable pulling frame, which then feeds the wire harness into the cable pulling frame. The cable pulling frame is provided with a torsion feedback device. The wire harness passing through the cable pulling frame passes through the torsion feedback device and works in conjunction with it. The coating bed is responsible for supporting the wire harness and fine-tuning its direction. A traction wheel is provided on the side of the cable pulling frame away from the cable routing frame. The traction wheel is rotatably connected to the coating bed. The wire harness passing through the torsion feedback device is mounted on the traction wheel. When the traction wheel rotates, it will drive the wire harness to move. The coating bed is also provided with... The winding frame has a speed-changing disc, a coating frame, and a speed-changing motor. A movable sleeve is mounted on the speed-changing motor, slidingly connected to and fitted onto the coating frame. Inside the coating frame is a tape mounting bracket, rotatably connected to the speed-changing disc. The speed-changing disc is slidably connected to the coating bed, which has a cutting component. Once the wire harness is installed, the winding frame is activated. The speed-changing disc powers the speed-changing motor, which moves the movable sleeve across the coating frame. The tape mounting bracket above the sleeve outputs tape to wind the wire harness. After winding, the cutting component cuts the tape, and finally, the tape mounting bracket secures the tape, completing the coating operation.

[0006] A winding device is installed on the traction wheel and is located at the output end of the winding motor. The winding device has a threading hole on its edge. The winding motor is inductively connected to the variable speed motor. A wire-straightening frame is installed on the traction wheel. During the winding process, the coated wire bundle is passed through the threading hole and around the wire-straightening frame. Then the winding motor is started, and the winding motor drives the winding frame to rotate, thereby pulling the wire bundle so that the coated wire bundle can enter the traction wheel.

[0007] The torsion feedback device includes a torsion ring and a through-wire ring, which are detachably connected. A directional clamp is fixedly connected inside the through-wire ring. The directional clamp is a flexible metal sheet. A feedback post is also slidably connected inside the through-wire ring. A sliding resistor is installed inside the through-wire ring. The feedback post and the sliding resistor are slidably connected. The feedback post and the sliding resistor are electrically connected to the torsion ring through wires. After the wire harness passes through the through-wire ring, the wire harness and the rubber coating will come into contact with the directional clamp. The directional clamp will detect the wire harness. When the directional clamp is pressed, it will slide within the sliding resistor, thereby determining the thickness of the current wire harness and the condition of the current wire harness coating.

[0008] The torsion ring has a torsion groove, and a mounting groove is slidably connected within the torsion groove. A torsion electromagnetic plate is installed inside the torsion ring. The wire pass ring and the mounting groove are detachably connected. A torsion magnetic block is installed on the mounting groove. The torsion electromagnetic plate works in conjunction with the torsion magnetic block. The torsion electromagnetic plate is inductively connected to the variable speed motor and the wound motor via a wire. When the wire harness passes through the wire pass ring, the wire pass ring will also be installed inside the torsion ring. When the wire harness drives the wire pass ring to rotate, it will drive the torsion magnetic block in the mounting groove to rotate. The torsion magnetic block works in conjunction with the torsion electromagnetic plate. The torsion electromagnetic plate contains an interference coil. A current of a specific frequency is input into the interference coil. Through electromagnetic interference, the current degree of torsion of the wire pass ring is determined, thereby controlling the coating speed of the variable speed motor and the winding speed of the wound motor to prevent excessive torsion from affecting the tension of the coating.

[0009] The winding frame is equipped with a compensating screw and a compensating motor. The compensating screw is located at the output end of the compensating motor, which is fixedly connected to the coating bed. The winding frame is slidably connected to the coating bed. The compensating screw passes through the winding frame and meshes with it. The compensating motor is inductively connected to the winding motor. During the coating process, by knowing the thickness of the wire harness, effective distance compensation can be performed to avoid problems such as excessively thick or thin coating. The compensating motor drives the compensating screw to rotate, thereby controlling the movement of the winding frame on the coating bed to compensate and correct the coating thickness.

[0010] The tape mounting bracket has teeth that mesh with the output end of the variable speed motor. A support groove is provided on the variable speed disc, and the tape mounting bracket is embedded in and slidably connected to the support groove. A tensioning bracket with a tensioning wheel is provided on the movable sleeve. The tensioning bracket and the movable sleeve are rotatably connected via a spring shaft. Before tape application, the variable speed motor is checked and started. The motor rotates, causing the tape mounting bracket to rotate on the tape mounting bracket. Tape is pre-installed in the tape mounting bracket. During tape application, the tensioning bracket will press against the back of the tape. Throughout the application process, the tensioning bracket maintains the tension of the tape.

[0011] The tape mounting frame is equipped with a tape collar, which is rotatably connected to the tape mounting frame. Multiple fixing pins are slidably connected to the tape collar, and each fixing pin contains a compression spring. Each compression spring abuts against the tape collar. The tape mounting frame also contains a traction speed change assembly. When installing the tape, the tape is installed on the tape collar, and the fixing pins inside the tape collar will insert into the tape's support shell, thus securing the tape. The compression springs support the fixing pins, and the tape collar rotates on the tape mounting frame to adapt to the tape wrapping operation.

[0012] The traction transmission assembly includes a follower wheel frame and a follower bracket. The follower wheel frame is rotatably connected to the follower bracket, and multiple follower balls are hinged on the follower wheel frame. The follower bracket and the tape mounting bracket are rotatably connected via a spring shaft. A displacement sensor is installed on the tape mounting bracket, and the displacement sensor is inductively connected to the transmission motor. During tape wrapping, the tape passes through the follower wheel frame and then through the follower bracket to perform the wrapping operation. Since the thickness, number, and angle of the wire harness all affect the wrapping operation, the sliding of the follower bracket is used in conjunction with the displacement sensor to determine the current condition of the wire harness and perform targeted wrapping operations. When the wire harness is thinner, the transmission motor speeds up; when the wire harness is thicker, the transmission motor slows down.

[0013] The cutting assembly includes a capture clamp and a compensation module. The capture clamp contains a cutting blade with a serrated edge. It also contains a cutting motor with a cutting linkage connected to the cutting blade. The compensation module includes a compensation cylinder and a compensation spring. The compensation spring is slidably connected to the capture clamp. After cutting, the compensation motor moves the winding frame to the wiring frame position, then activates the capture clamp and compensation cylinder. The compensation cylinder moves the compensation spring to capture the tape, and the cutting motor drives the cutting blade to cut the tape thoroughly using the serrated edge.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs an automatic following compensation-type tape wrapping component. Utilizing a circular track-like structure, it can wrap different types of wire harnesses. Simultaneously, the compensation component automatically coordinates with the torsion feedback device. While adjusting the wire tension, the compensation component also compensates for wire harnesses at different angles and postures, ensuring more consistent tape thickness at different positions and preventing tape wrinkling and detachment during subsequent bending of the wire harness. Furthermore, the automatic following structure allows for automatic tracking of the wire harness, and sensors control the winding speed of the winding motor, resulting in more uniform tape dispensing. This prevents tape breakage and reduces excessive compression and deformation of the wire harness caused by uneven tape winding. Additionally, this application employs an automatic cutting structure for automatic tape capture and cutting, ensuring more precise tape dispensing. Attached Figure Description

During the winding process, the coated wire bundle is passed through the wire-passing hole and around the wire-strapping frame 602. Then the winding motor 603 is started, and the winding motor 603 drives the winding frame 7 to rotate, thereby pulling the wire bundle so that the coated wire bundle can enter the traction wheel 6.

[0020] The torsion feedback device 5 includes a torsion ring 501 and a wire-passing ring 502, which are detachably connected.

After the wire harness passes through the wire-passing ring 502, the wire harness and the rubber-coated part will come into contact with the directional clamp 503. The directional clamp 503 will detect the wire harness. When the directional clamp 503 is pressed, it will slide within the sliding resistor 505, thereby knowing the current thickness of the wire harness and the current rubber-coated condition of the wire harness.

[0021] A torsion groove 506 is provided inside the torsion ring 501, and an installation groove 507 is slidably connected inside the torsion groove 506.

When the wire harness passes through the wire pass ring 502, the wire pass ring 502 will also be installed on the torsion ring 501. Within 1, when the through ring 502 rotates, the torsion ring 501 will drive the torsion magnetic block 509 in the mounting groove 507 to rotate. The torsion magnetic block 509 works in conjunction with the torsion electromagnetic plate 508. The torsion electromagnetic plate 508 is loaded with an interference coil. A current of a specific frequency is input into the interference coil. Through electromagnetic interference, the current degree of torsion of the through ring 502 is obtained, thereby controlling the coating speed of the variable speed motor 10 and the winding speed of the winding motor 603 to avoid excessive torsion that would affect the tension of the coating.

[0022] The winding frame 7 is equipped with a compensating screw rod 701 and a compensating motor 702. The compensating screw rod 701 is located on the output end of the compensating motor 702. The compensating motor 702 is fixedly connected to the coating bed 1, and the winding frame 7 is slidably connected to the coating bed 1.

The variable speed motor 10 rotates, driving the tape mounting bracket 12 to rotate on the tape mounting bracket 9. The tape is pre-installed in the tape mounting bracket 12. During the tape coating process, the tension bracket 803 will press against the back of the tape. Subsequently, during the tape coating process, the tension bracket 803 will always ensure the tension of the tape.

[0024] The tape mounting frame 12 is provided with a tape collar 1201, which is rotatably connected to the tape mounting frame 12. Multiple fixing pins 1202 are slidably connected to the tape collar 1201. Each fixing pin 1202 is provided with a compression spring 1203, which abuts against the tape collar 1201. The tape mounting frame 12 is also provided with a traction transmission assembly 1204. When installing the tape, the tape is installed on the tape collar 1201. The fixing pins 1202 in the tape collar 1201 will insert into the support shell of the tape, thus securing the tape. The compression springs 1203 support the fixing pins 1202, and the tape collar 1201 rotates on the tape mounting frame 12 to adapt to the tape wrapping operation.

[0025] The traction transmission assembly 1204 includes a follower wheel frame 1205 and a follower frame 1206. The follower wheel frame 1205 is rotatably connected to the follower frame 1206.

A displacement sensor 1208 is provided on the tape mounting frame 12. The displacement sensor 1208 is inductively connected to the transmission motor 10. During tape wrapping, the tape passes through the follower wheel frame 1205 and then through the follower frame 1206 to perform the tape wrapping operation. Since the thickness, number of wires, and angle of the wire harness all affect the tape wrapping operation, the sliding of the follower frame 1206 is used in conjunction with the displacement sensor 1208 to determine the current condition of the wire harness and perform targeted tape wrapping operations. When the wire harness is thinner, the transmission motor 10 speeds up; when the wire harness is thicker, the transmission motor 10 slows down.

[0026] The cutting assembly 13 includes a capture clamp 1301 and a compensation module 1302. The capture clamp 1301 is equipped with a cutting blade 1303, which has a serrated edge.

The compensation module 1302 includes a compensation cylinder 1306 and a compensation spring. The compensation spring is slidably connected to the capture clamp 1301. After the cutting is completed, the compensation motor 702 will also move the winding frame 7 to the position of the wiring frame 2. Then, the capture clamp 1301 and the compensation cylinder 1306 will be activated. The compensation cylinder 1306 will drive the compensation spring to move, thereby capturing the tape. The cutting motor 1304 will drive the cutting blade 1303 to cut the tape fully, using the serrated cutting blade 1303 to cut the tape.

[0027] Working principle: The wire harness is passed through the transmission hole 3 and then fed into the wire pulling frame 4. After passing through the wire pulling frame 4, the wire harness passes through the torsion feedback device 5, which starts the winding frame 7. The speed change disk 8 on the winding frame 7 supplies power to the speed change motor 10 and passes around the winding frame 602. Then the winding motor 603 is started, which drives the winding frame 7 to rotate. The speed change motor 10 drives the moving sleeve 11 to move on the rubber-coated frame 9. After the wire harness passes through the through ring 502, the wire harness and the rubber-coated part will contact the directional clamp 503. The directional clamp 503 will detect the wire harness. When the wire harness drives the through ring 502 to rotate, it will drive the torsion magnetic block 509 in the mounting groove 507 to rotate. The torsion magnetic block 509 works in conjunction with the torsion electromagnetic plate 508. The torsion electromagnetic plate 508 is loaded with interference current. A specific frequency current is input into the interference coil. Through electromagnetic interference, the degree of twist of the current wire loop 502 is obtained. By knowing the thickness of the wire harness, effective distance compensation can be performed. The tape mounting bracket 12 above it will output tape. The sliding of the follower bracket 1206 and the displacement sensor 1208 are used in conjunction. The speed change plate 8 on the winding bracket 7 supplies power to the speed change motor 10. The speed change motor 10 drives the moving sleeve 11 to move on the wrapping bracket 9. The tape mounting bracket 12 above it will output tape. After the cutting is completed, the compensation motor 702 will also move the winding bracket 7 to the position of the wire routing bracket 2. Then the capture clamp 1301 and the compensation cylinder 1306 are activated. The compensation cylinder 1306 drives the compensation spring to move, thereby capturing the tape. The cutting blade 1303 performs full cutting.
