Description

Technical Field

[0001] The invention belongs to the technical field of wire harness processing equipment, and in particular relates to a wire harness tape winding device. Background Art

[0002] As an important part of the manufacturing industry, the wire harness processing industry is inseparable from the support of wire harnesses, from household appliances to high-end automobiles, from ordinary communication equipment to high-end medical equipment. With the advancement of science and technology, the wire harness processing industry is developing in the direction of high precision, high efficiency and high quality. The wire harness is a connecting component that connects various electrical devices in the circuit. It realizes the connection, transmission and separation of electrical signals through connectors and lines. It is the basic component necessary for the connection of the entire system. The outer periphery of the wire harness is wrapped with tape to play the role of marking, fixing and insulation. Generally, multiple wire harnesses are wrapped together with tape.

[0003] In the prior art (the publication number is CN117690663B, and the patent name is a patent application for a wire harness tape winding device), the guiding mechanism and the deviation correction mechanism are used to limit the transmission direction of the wire harness, so as to avoid the twisting of the wire harness under the radial tension of the tape, so that the twisting situation is superimposed and the wire harness sheath is damaged. The release mechanism can be used to buffer the problem of a sudden increase in radial torsional force when the tape is torn because the tearing force of part of the tape is too large, thereby improving the safety of wire harness winding. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] If the tape cannot be fixed during the winding process and shakes, the edges of the tape may contact and stick together, resulting in uneven winding, affecting the appearance and protective effect of the wire harness. Severe shaking of the tape may cause the tape to fall off and may require rewinding, increasing production time and cost. When the cutting device cuts the tape, if the tape is not fully fixed, the cut edge is likely to curl up, forming an irregular end, which not only affects the appearance quality of the product, but may also cause other problems in subsequent operations.

[0018] A wire harness tape winding device of the present invention:

[0019] 1. The wire harness tape winding device first needs to install the tape on the placement shaft. After the tape is installed, the pressing column is pressed, and the pressing column pushes the moving block to move. The moving block pushes the pushing plate to move through the connecting shaft, and the pushing plate drives the expansion fixing part to expand outward. The expanding expansion fixing part fixes the tape. After the fixing is completed, the straight surface restriction of the trapezoidal clamping block restricts the movement of the clamping plate, thereby preventing the moving block from loosening and affecting the fixing effect of the expansion fixing part. When the tape is used up, the microswitch notifies to replace the tape through compression, and the staff lifts the L-shaped lifting rod, and the L-shaped lifting rod drives the trapezoidal clamping block to move, restricting the clamping plate from breaking away from the restriction of the trapezoidal clamping block. The reset spring pushes the moving block and the pressing column to reset. After resetting, the moving block pulls the pushing plate and the hinged seat to move, thereby releasing the clamping of the expansion fixing part on the tape. This arrangement is convenient for replacing the tape while fixing the tape to prevent the edges of the tape from contacting each other and sticking together due to shaking during the winding process.

[0020] 2. The wire harness tape winding device pulls out the tape after installation. The tape passes through the bottom of the tensioning roller. The tensioning spring drives the lower pressure plate and the tensioning roller to press the tape. The appropriate tension helps to ensure that the tape is evenly distributed along the predetermined path during the winding process to avoid tape overlap or deviation. Then the tape is attached to a rod relatively close to the top of the tape conveyor. The reduction motor 2 is started. The reduction motor 2 drives the tape conveyor to rotate 90° through the shaft. The tape conveyor pulls the tape out to a predetermined length. The annular positioning plate squeezes the limit extrusion rod. When the limit extrusion rod moves along the annular positioning plate, the limit extrusion rod suddenly moves from the straight surface close to the annular positioning plate to the straight surface farther away, the limit extrusion rod releases the restriction on the reset circular plate, and the compression spring pushes the reset circular plate to reset, and the reset circular plate pushes the L-shaped clamping plate to rotate with the fixed axis as the axis, so that the L-shaped clamping plate can clamp the tape to prevent the tape from shifting during the conveying and cutting process, and further prevent the tape from warping after being cut, affecting the next winding, thereby ensuring that the tape can be supplied smoothly.

[0021] 3. For the wire harness tape winding device, after the robotic arm positions the tape winding machine to the position, the reduction motor rotates to drive the driving gear to rotate, so that the driving gear moves downward along the fixed tooth plate, thereby moving the translation bracket plate downward. During the downward movement of the translation bracket plate, the T-shaped pressure plate pushes the lower pressure bracket to descend, and the lower pressure bracket pushes the lower pressure rod to move through the limit shaft. The lower pressure rod pushes the square sliding rod and the wire harness clamping plate to move toward the wire harness through the mounting shaft, and the wire harness clamping plates on both sides clamp the wire harness to ensure that the wire harness remains stable and motionless during the winding process.

[0022] 4. The wire harness tape winding device, after the wire harness clamping mechanism clamps the wire harness, the fork of the tape conveyor is pressed onto the wire harness, and then the reduction motor three is started to drive the driving gear to rotate, and the reduction motor three moves down along the connecting tooth plate, so that the cutting frame moves toward the tape, and the cutting frame drives the cutting claw to approach the tape. The right side of the cutting claw is a round mouth, and the left side is a cutting edge. In the process of pressing down the cutting claw, the cutting edge will cut the tape. After continuing to press down, because the cutting claw is an elastic sheet material, the wire harness enters the cutting The tape is wrapped around the wire harness in the recess of the female claw to complete the tape winding. When the cutting female claw is in the cutting tape, the suction cup is attached to the tape. When the cutting mechanism continues to descend while cutting the tape, the mobile connecting frame pushes the L-shaped pressure rod to descend. The L-shaped pressure rod pushes the piston to descend in the hollow box, thereby generating negative pressure in the hollow box. The suction hose generates negative pressure on the suction cup through the exhaust pipe, which can make the suction cup absorb the tape, ensuring that the tape remains stable during the winding process and preventing the tape from curling up after cutting and affecting the winding effect.

When the tape continues to cover the wire harness, the tape may detach from the wire harness due to various reasons and cannot be firmly attached. This situation not only affects the protection effect of the wire harness, but also may cause shutdown and rework on the production line, increasing production costs. The inner wall of the translation bracket plate 105 is provided with an adsorption mechanism 7, and the adsorption mechanism 7 includes a hollow box 701 fixedly connected to the inner wall of the translation bracket plate 105, and the inner wall of the hollow box 701 is fixedly connected to a fixed slide rod 702, and the outer wall of the fixed slide rod 702 is slidably connected to a piston 703, and the top of the piston 703 is fixedly connected to an L-shaped pressure rod 704, and the outer wall of the L-shaped pressure rod 704 is provided with a U-shaped movable frame 705, and the top of the U-shaped movable frame 705 It is fixedly connected to the bottom of the mobile connecting frame 603, and is connected to the top of the hollow box 701 with an air suction hose 706. The outer wall of the air suction hose 706 is connected to an exhaust pipe 707. The bottom end of the exhaust pipe 707 is provided with a suction cup 708. This arrangement is that when the cutting claw 609 is in the cutting tape, the suction cup 708 is attached to the tape. When the cutting mechanism 6 continues to descend while cutting the tape, the mobile connecting frame 603 pushes the L-shaped pressure rod 704 to descend, and the L-shaped pressure rod 704 pushes the piston 703 to descend in the hollow box 701, thereby generating negative pressure in the hollow box 701. The air suction hose 706 generates negative pressure on the suction cup 708 through the exhaust pipe 707, so that the suction cup 708 can adsorb the tape, thereby ensuring that the tape remains stable during the winding process and preventing the tape from curling up after cutting and affecting the winding effect.

[0054] The working principle of a wire harness tape winding device is as follows: first, the tape needs to be installed on the placement shaft 202. After the tape is installed, the pressing column 34 is pressed. The pressing column 34 pushes the moving block 32 to move. The moving block 32 pushes the pushing plate 36 to move through the connecting shaft 35. The pushing plate 36 drives the expansion fixing member 38 to expand outward. The expanding expansion fixing member 38 fixes the tape. After the fixing is completed, the straight surface of the trapezoidal block 302 limits the movement of the card plate 305, thereby preventing the moving block 32 from loosening and affecting the fixing effect of the expansion fixing member 38. When the tape is used up, the micro-motion The switch 208 is compressed to notify the tape to be replaced. The staff lifts the L-shaped lifting rod 304, which drives the trapezoidal block 302 to move, and the limiting plate 305 is separated from the restriction of the trapezoidal block 302. The reset spring 33 pushes the moving block 32 and the pressing column 34 to reset. After the reset, the moving block 32 pulls the pushing plate 36 and the hinge seat 37 to move, thereby releasing the clamping of the expansion fixing member 38 on the tape. This arrangement is convenient for replacing the tape and fixing the tape at the same time, preventing the edges of the tape from contacting each other and sticking together due to shaking during the winding process.

[0055] After the tape is installed, it is pulled out and passed through the bottom of the tensioning roller 207. The tensioning spring 204 drives the lower pressure plate 205 and the tensioning roller 207 to press the tape. The appropriate tension helps to ensure that the tape is evenly distributed along the predetermined path during the winding process to avoid overlapping or offsetting of the tape. The tape is then glued to a rod relatively close to the top of the tape conveyor 503, and the reduction motor 501 is started. The reduction motor 501 drives the tape conveyor 503 to rotate 90° through the rotating shaft 502. The tape conveyor 503 pulls the tape out to a predetermined length. Due to the restriction of the annular positioning plate 510 on the limit extrusion rod 509, when the limit When the limiting extrusion rod 509 moves along the annular positioning plate 510, when the limiting extrusion rod 509 suddenly moves from the straight surface close to the annular positioning plate 510 to the straight surface farther away, the limiting extrusion rod 509 releases the restriction on the reset circular plate 505, and the compression spring 504 pushes the reset circular plate 505 to reset, and the reset circular plate 505 pushes the L-shaped clamping plate 507 to rotate with the fixed shaft 506 as the axis, so that the L-shaped clamping plate 507 can clamp the tape to prevent the tape from deviating during the conveying and cutting process, and further prevent the tape from warping after being cut, which affects the next winding, and ensures that the tape can be supplied smoothly;

[0056] After the robotic arm 101 positions the tape winding machine, the reduction motor 106 rotates to drive the driving gear 107 to rotate, so that the driving gear 107 moves downward along the fixed tooth plate 108, thereby moving the translation support plate 105 downward. During the downward movement of the translation support plate 105, the T-shaped pressing plate 411 pushes the pressing support 409 to descend, and the pressing support 409 pushes the pressing rod 406 to move through the limiting shaft 407. The pressing rod 406 pushes the square sliding rod 403 and the harness clamping plate 404 to move toward the harness through the mounting shaft 405. The harness clamping plates 404 on both sides clamp the harness to ensure that the harness remains stable and motionless during the winding process.

[0057] After the harness clamping mechanism 4 clamps the harness, the fork of the tape conveyor 503 is pressed onto the harness, and then the reduction motor 3 604 is started to drive the driving gear 605 to rotate, and the reduction motor 3 604 moves down along the connecting tooth plate 606, so that the cutting frame 607 moves toward the direction of the tape, and the cutting frame 607 drives the cutting claw 609 to approach the tape. The right side of the cutting claw 609 is a round mouth, and the left side is a cutting edge. During the downward pressing process of the cutting claw 609, the cutting edge will cut the tape. After continuing to press down, because the cutting claw 609 is an elastic sheet material, the harness enters the notch of the cutting claw 609, allowing the tape to wrap around the harness, completing the tape winding;

[0058] When the cutting claw 609 is in the process of cutting the tape, the suction cup 708 is attached to the tape. When the cutting mechanism 6 continues to descend while cutting the tape, the mobile connecting frame 603 pushes the L-shaped pressure rod 704 to descend. The L-shaped pressure rod 704 pushes the piston 703 to descend in the hollow box 701, thereby generating negative pressure in the hollow box 701. The suction hose 706 generates negative pressure on the suction cup 708 through the exhaust pipe 707, which can make the suction cup 708 absorb the tape, ensuring that the tape remains stable during the winding process and preventing the tape from curling up after cutting and affecting the winding effect.
