Description

Technical Field

[0001] This utility model relates to the field of automation, and in particular to a self-winding tube threading device. Background Technology

[0002] Self-winding tubing is a commonly used sheathing material in many industries. For example, in electrical wiring inside or outside buildings, it effectively protects wires and cables from mechanical damage, moisture, or corrosion. In automotive manufacturing, it's often used to organize and protect complex wire harnesses, ensuring their safety and reliability inside and under the vehicle. In machinery, it guides, secures, and protects various linear objects, such as sensor wires, power lines, and control lines. These applications all require wrapping wires, cables, and power lines with self-winding tubing. Currently, these wrapping methods rely on traditional "small airplane" jigs for manual threading, which is extremely inefficient and labor-intensive. This new equipment can automate the manual threading process, greatly simplifying the self-winding tubing process. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a self-winding tube threading device to improve the efficiency of wrapping wire harnesses into self-winding tubes.

[0004] Therefore, one embodiment provides a self-winding tube threading device, comprising:

[0005] A wire feeding rack is used to hold and continuously supply the self-winding tube;

[0012] As a further alternative to the self-winding tube threading device, the driving component includes a second motor, a gear, and a rack. The gear is rotatably connected to the gripper, and the gear and the rack mesh. The second motor drives the gear to rotate, thereby causing the gear to move the gripper on the rack.

[0013] As a further alternative to the self-winding tube threading device, the drive assembly further includes a guide rod, and the gripper is provided with a guide hole. The guide rod passes through the guide hole to allow the gripper to move along the axial direction of the guide rod.

[0014] As a further alternative to the self-winding tube threading device, the height of the first stop is the same as the height of the second stop.

[0015] As a further optional embodiment of the self-winding tube threading device, the flaring assembly includes a first flaring member, which includes a first guide portion and a first limiting portion. When the self-winding tube passes through the first guide portion and the first limiting portion in sequence, the first guide portion expands the self-winding tube, and the first limiting portion is used to restrict the upward movement of the opening edge of the self-winding tube.

[0016] As a further optional solution for the self-winding tube threading device, the flaring assembly further includes a second flaring member, which includes a second guide portion and a second limiting portion. The first flaring member is disposed between the second flaring member and the wire feeding frame.

[0017] As a further alternative to the self-winding tube threading device, the cutting component is disposed between the first flaring member and the second flaring member.

[0018] As a further alternative to the self-winding tube threading device, the cutting assembly includes a cylinder and a cutter, the cylinder being used to drive the cutter to move so that the cutter cuts the self-winding tube.

[0019] Implementing the embodiments of this utility model will have the following beneficial effects:

[0020] According to the self-winding tube threading device in the above embodiments, the wire harness is first placed between the first and second stops of the tube expanding fixture. A wire feeding frame is used to hold the self-winding tube, and a drive assembly sequentially moves the self-winding tube from the flaring assembly and the tube expanding fixture. As the self-winding tube passes through the flaring assembly, it is expanded, changing from an overlapping structure to an open shape. Then, the opening of the self-winding tube is caught on the first and second stops, straightening the wire harness and moving it upwards into the enclosure of the self-winding tube. Continuing to move the wire harness upwards, the wire harness drives the self-winding tube to move until the opening of the self-winding tube moves out of the first and second stops. The inherent properties of the self-winding tube cause the opening to close, thus enclosing the wire harness. The cutting device typically cuts the self-winding tube before moving the wire harness, making it easier to insert the wire harness into the self-winding tube. Implementing the self-winding tube threading device of this invention can improve the efficiency of wrapping the wire harness into the self-winding tube. Attached Figure Description

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] This utility model provides a self-winding tube threading device, please refer to... Figures 1-7 The self-winding tube threading device includes a wire feeding frame 10, a flaring assembly 20, a tube flaring fixture 30, a drive assembly 40, and a cutting assembly 50.

[0036] The pay-off frame 10 is used to hold and continuously supply the self-winding tube 100. The flaring assembly 20 is used to expand the self-winding tube 100 from an overlapping structure into an open shape. The tube-expanding fixture 30 has a first flange 310 and a second flange 320, which are arranged opposite to each other, and the space between the first flange 310 and the second flange 320 can be used to place the wire harness. The drive assembly 40 is used to drive the self-winding tube 100 sequentially from the pay-off frame 10 through the flaring assembly 20 and the tube-expanding fixture 30. The cutting assembly 50 is disposed between the pay-off frame 10 and the flaring assembly 20, and is used to cut the self-winding tube 100.

[0037] According to the self-winding tube threading device in the above embodiments, the wire harness is first placed between the first stop 310 and the second stop 320 of the tube expanding fixture 30. The wire feeding frame 10 is used to place the self-winding tube 100, and the driving component 40 sequentially moves the self-winding tube 100 through the flaring component 20 and the tube expanding fixture 30. When the self-winding tube 100 passes through the flaring component 20, it is expanded, changing the self-winding tube 100 from an overlapping structure to an open shape. Then, the opening of the self-winding tube 100 is caught on the first stop 310 and the second stop 320, straightening the wire harness and moving it upward into the enclosure of the self-winding tube 100. The wire harness continues to move upward, and the wire harness drives the self-winding tube 100 to move until the opening of the self-winding tube 100 moves out of the first stop 310 and the second stop 320. The inherent properties of the self-winding tube 100 cause the opening of the self-winding tube 100 to close, thereby wrapping the wire harness. The cutting device typically cuts the self-winding tube 100 before moving the wire harness, making it easier to insert the wire harness into the self-winding tube 100. Implementing the self-winding tube threading device of this utility model can improve the efficiency of wrapping the wire harness into the self-winding tube 100.

[0038] The initial self-winding tube 100 is generally disc-shaped, and the pay-off frame 10 is generally equipped with a roller, on which the self-winding tube 100 is wound. When the drive assembly 40 pulls the self-winding tube 100, the self-winding tube 100 drives the roller to rotate. Generally, the pay-off frame 10 is also equipped with multiple idlers to guide the direction in which the self-winding tube 100 is dragged, preventing the moved self-winding tube 100 from deviating from the position corresponding to the flaring assembly 20.

[0039] In some specific embodiments, the drive assembly 40 includes a first motor 440 and a pressure roller 410. The first motor 440 is used to drive the pressure roller 410 to rotate, and the pressure roller 410 is used to drive the self-winding tube 100 to move along the axial direction of the self-winding tube 100.

[0040] In this embodiment, the pressure roller 410 abuts against the self-winding tube 100 and is driven to rotate by the first motor 440. The friction between the pressure roller 410 and the self-winding tube 100 causes the self-winding tube 100 to move along its own axis.

[0041] In some specific embodiments, the drive assembly 40 further includes a drive member 420 and a gripper 430, the gripper 430 being used to grip the self-winding tube 100, and the drive member 420 being used to drive the gripper 430 to move along the axial direction of the self-winding tube 100.

[0042] The gripper 430 can open and close, either manually or electrically. The gripper 430 holds one end of the self-winding tube 100, and then the drive unit 420 drives the gripper 430 to move, so that the self-winding tube 100 is dragged and finally the self-winding tube 100 can be smoothly moved onto the tube expanding fixture 30.

[0043] In some specific embodiments, the drive unit 420 includes a second motor (not shown), a gear 4210 and a rack 4220. The gear 4210 is rotatably connected to the gripper 430. The gear 4210 and the rack 4220 mesh. The second motor drives the gear 4210 to rotate, thereby causing the gear 4210 to drive the gripper 430 to move on the rack 4220.

[0044] The second motor is generally fixedly connected to the gripper 430 and drives the rotation of the gear 4210. Since the gear 4210 meshes with the rack 4220, the gear 4210 forces the second motor and the gripper 430 to move along the length of the rack 4220. Ultimately, this achieves the purpose of moving the gripper 430.

[0045] In some specific embodiments, the drive assembly 40 further includes a guide rod 4230, and the gripper 430 is provided with a guide hole. The guide rod 4230 passes through the guide hole so that the gripper 430 moves along the axial direction of the guide rod 4230.

[0046] The guide rod 4230 mainly serves as a guide to prevent the gripper 430 from vibrating or shifting during movement.

[0047] In some specific embodiments, the height of the first stop 310 is higher than the height of the second stop 320.

[0048] In this embodiment, the height of the first stop 310 is higher than the height of the second stop 320. When the self-winding tube 100 detaches from the tube expanding fixture 30, the height difference between the first stop 310 and the second stop 320 ensures that the self-winding tube 100 can be completely closed when it closes. This prevents the two sides of the opening of the self-winding tube 100 from abutting against each other, which could result in insufficient closure of the self-winding tube 100.

[0049] It should be noted that the upper edges of the first retaining edge 310 and the second retaining edge 320 are generally provided with a third limiting part 321, which is used to prevent the self-coiling tube 100 from coming out of the tube expanding fixture 30. In addition, the third limiting part 321 cannot completely limit the self-coiling tube 100, otherwise it will not be easy for the self-coiling tube 100 to come out of the tube expanding fixture later.

[0050] In some specific embodiments, the flaring assembly 20 includes a first flaring member 210, which includes a first guide portion 2110 and a first limiting portion 2120. When the self-winding tube 100 passes through the first guide portion 2110 and the first limiting portion 2120 in sequence, the first guide portion 2110 expands the self-winding tube 100, and the first limiting portion 2120 is used to restrict the upward movement of the opening edge of the self-winding tube 100.

[0051] In this embodiment, the first guide portion 2110 is generally conical or frustum-shaped. The widest part of the first guide portion 2110 should be greater than the diameter of the self-winding tube 100, and the narrowest part of the second guide portion 2210 should be smaller than the diameter of the self-winding tube 100. The first limiting portion 2120 generally has a T-shaped cross-section to prevent the self-winding tube 100 from coming out of the first flared part 210.

[0052] In some specific embodiments, the flaring assembly 20 further includes a second flaring member 220, which includes a second guide portion 2210 and a second limiting portion 2220. The first flaring member 210 is disposed between the second flaring member 220 and the wire feeding frame 10. When the self-winding tube 100 passes through the second limiting portion 2220 and the second guide portion 2210 in sequence, the second limiting portion 2220 is used to restrict the upward movement of the opening edge of the self-winding tube 100, and the second guide portion 2210 expands the self-winding tube 100.

[0053] The second flaring member 220 is provided to further enlarge the opening of the self-winding tube 100, thereby accommodating thicker wire harnesses. When the self-winding tube 100 passes through the second flaring member 220, it first passes through the second limiting part 2220 to maintain the opening shape, and then passes through the second guide part 2210 to further enlarge the opening. The second guide part 2210 is generally also frustoconical in shape.

[0054] Normally, the self-winding tube 100 cannot be expanded to the required extent through a single flaring; otherwise, the opening of the self-winding tube 100 will burst open and cannot be closed by the limiting part. In other words, the slope of the guide part cannot be too large, nor can the guide part be made too long. In this embodiment, through the cooperation of the first flaring member 210 and the second flaring member 220, the purpose of both expanding the self-winding tube 100 to a certain opening extent and preventing the self-winding tube 100 from being unable to be closed after opening is achieved.

[0055] In some specific embodiments, the cutting component 50 is disposed between the first flaring member 210 and the second flaring member 220.

[0056] In this embodiment, the cutting component 50 is provided in the first flaring part 210 and the second flaring part 220, so that the two sides of the cut self-winding tube 100 cannot automatically close, thus facilitating the next round of operation.

[0057] In some specific embodiments, the cutting assembly 50 includes a cylinder 510 and a cutter (not shown), the cylinder 510 being used to drive the cutter to move so that the cutter cuts the self-winding tube 100.

[0058] The cylinder 510 has a large impact force, which enables the cutter to cut the self-winding tube 100 in one go.

[0059] In all the above embodiments, self-winding tubes 100 of different specifications can wrap wire harnesses of different thicknesses. When it is necessary to replace the self-winding tubes 100 of different specifications, the distances between the first flared part 210, the second flared part 220, the first stop 310, and the second stop 320 also need to be adjusted.

[0060] Preferably, the first flared part 210 and the second flared part 220 are detachable from the self-winding tube threading device of this utility model, thereby matching self-winding tubes 100 of different specifications. The distance between the first flange 310 and the second flange 320 is adjustable, thereby accommodating self-winding tubes 100 of different specifications.

[0061] In some specific embodiments, a control system and sensors are also included. The sensors detect the self-winding tube 100 and the cable to ensure the cable is accurately fed into the self-winding tube 100, preventing misalignment and damage. Specifically, the control system can control the first motor 440, the second motor, the gripper 430, and the cylinder 510, etc. The sensors can detect information such as the position and length of the self-winding tube 100. Automated operation is achieved through pre-set software.

[0062] In some specific embodiments, the system also includes an emergency stop button, a protective cover, and an alarm system. The emergency stop button can be pressed in an emergency to stop the machine. The protective cover prevents accidental injury to operators, and the alarm system serves as a hazard or malfunction notification.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
