[0002] Self-winding tubes are a commonly used sheath in many industries. For example, when conducting electrical wiring inside or outside a building, self-winding tubes can effectively protect wires and cables from mechanical damage, moisture or corrosion. In the automobile manufacturing process, self-winding tubes are often used to organize and protect complex wiring harnesses to ensure their safety and reliability inside and under the vehicle. In mechanical equipment, self-winding tubes can be used to guide, fix and protect various linear objects, such as sensor wires, power cords, control cords, etc. Application scenarios such as the above all require wires, cables, power cords and other wiring harnesses to be wrapped with self-winding tubes. Currently, these wrapping methods all use traditional "small airplane" jigs for manual threading, which is extremely unsatisfactory in terms of efficiency and manpower. Therefore, this equipment can automatically replace manual threading, bringing great convenience to self-winding tube threading. Summary of the invention

[0032] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] In an embodiment of the present invention, a wire threading device for a self-rolling tube is provided. Please refer to Figures 1-7 . The wire threading device for the self-rolling tube includes a wire pay-off rack 10, a flaring assembly 20, a tube expanding jig 30, a driving assembly 40 and a cutting assembly 50.

[0036] The wire reel 10 is used to place the self - coiling tube 100 and continuously supply the self - coiling tube 100. The flaring assembly 20 is used to expand the self - coiling tube 100 from a coincident structure into an open shape. The tube expanding jig 30 has a first edge 310 and a second edge 320, which are arranged oppositely, and the space between the first edge 310 and the second edge 320 can be used to place the wire harness. The driving assembly 40 is used to drive the self - coiling tube 100 to pass through the flaring assembly 20 and the tube expanding jig 30 in sequence from the wire reel 10. The cutting assembly 50 is arranged between the wire reel 10 and the flaring assembly 20, and the cutting assembly 50 is used to cut the self - coiling tube 100.

[0037] According to the self - coiling tube threading device in the above embodiments, first, the wire harness is placed between the first edge 310 and the second edge 320 of the tube expanding jig 30. The wire reel 10 is used to place the self - coiling tube 100, and the driving assembly 40 drives the self - coiling tube 100 to pass through the flaring assembly 20 and the tube expanding jig 30 in sequence. When the self - coiling tube 100 passes through the flaring assembly 20, it is expanded, so that the self - coiling tube 100 changes from a coincident structure to an open shape. Then, the opening of the self - coiling tube 100 is stuck on the first edge 310 and the second edge 320, and the wire harness is straightened and moved upward into the surrounding range of the self - coiling tube 100. Continuing to move the wire harness upward, the wire harness drives the self - coiling tube 100 to move until the opening of the self - coiling tube 100 moves out of the first edge 310 and the second edge 320, and the self - nature of the self - coiling tube 100 causes the opening of the self - coiling tube 100 to close and wrap the wire harness. The cutting device generally cuts off the self - coiling tube 100 before moving the wire harness, so that the wire harness can be more easily incorporated into the self - coiling tube 100. Implementing the self - coiling tube threading device in the present invention can achieve the purpose of improving the efficiency of wrapping the wire harness into the self - coiling tube 100.

[0038] The initial self - coiling tube 100 is generally in a disk shape. The wire reel 10 is generally provided with a disk wheel, and the self - coiling tube 100 is wound around the disk wheel. When the driving assembly 40 pulls the self - coiling tube 100, the self - coiling tube 100 drives the disk wheel to rotate. Generally, the wire reel 10 is also provided with a plurality of idler rollers, so as to guide the direction of the self - coiling tube 100 being dragged and prevent the moving self - coiling tube 100 from deviating from the position corresponding to the flaring assembly 20.

[0039] In some specific embodiments, the driving 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 - coiling tube 100 to move along the axial direction of the self - coiling tube 100.

[0040] In this embodiment, the pressure roller 410 abuts against the self - coiling tube 100 and rotates under the drive of the first motor 440. The frictional force between the pressure roller 410 and the self - coiling tube 100 causes the self - coiling tube 100 to move along its own axis direction.

[0041] In some specific embodiments, the driving assembly 40 further includes a driving member 420 and a clamping jaw 430. The clamping jaw 430 is used to clamp the self - coiling tube 100, and the driving member 420 is used to drive the clamping jaw 430 to move along the axial direction of the self - coiling tube 100.

[0042] The clamping jaw 430 can be opened and closed, which can be manually or electrically operated. The clamping jaw 430 clamps one end of the self - coiling tube 100, and then the driving member 420 drives the clamping jaw 430 to move, so that the self - coiling tube 100 is dragged, and finally the self - coiling tube 100 can be smoothly moved onto the tube - expanding jig 30.

[0043] In some specific embodiments, the driving member 420 includes a second motor (not shown in the figure), a gear 4210, and a rack 4220. The gear 4210 is rotatably connected to the clamping jaw 430, the gear 4210 meshes with the rack 4220, and the second motor drives the gear 4210 to rotate, thereby driving the clamping jaw 430 to move on the rack 4220.

[0044] The second motor is generally fixedly connected to the clamping jaw 430 by driving the rotation of the gear 4210. Since the gear 4210 meshes with the rack 4220, the gear 4210 forces the second motor and the clamping jaw 430 to move along the length direction of the rack 4220. Finally, the purpose of driving the clamping jaw 430 to move is achieved.

[0045] In some specific embodiments, the driving assembly 40 further includes a guide rod 4230. The clamping jaw 430 is provided with a guide hole, and the guide rod 4230 is inserted through the guide hole to enable the clamping jaw 430 to move along the axial direction of the guide rod 4230.

[0046] The guide rod 4230 mainly plays a guiding role to prevent the clamping jaw 430 from vibrating or deviating during the movement.

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

[0048] In this embodiment, the height of the first edge 310 is higher than the height of the second edge 320. When the self - coiling tube 100 is separated from the tube - expanding jig 30, due to the height difference between the first edge 310 and the second edge 320, the self - coiling tube 100 can be completely closed when it is closed. This avoids the two sides at the opening of the self - coiling tube 100 from abutting against each other, resulting in insufficient closing degree of the self - coiling tube 100.

[0049] It should be noted that a third limiting portion 321 is generally provided on the upper edges of the first side edge 310 and the second side edge 320. The third limiting portion 321 is used to prevent the self - coiling tube 100 from disengaging from the tube - expanding fixture 30. In addition, the third limiting portion 321 cannot completely limit the self - coiling tube 100, otherwise it will not be easy to remove the self - coiling tube 100 from the tube - expanding fixture in the later stage.

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

[0051] In this embodiment, the first guiding portion 2110 is generally conical or frustum - shaped. The widest part of the first guiding portion 2110 should be larger than the diameter of the self - coiling tube 100, and the narrowest part of the second guiding portion 2210 should be smaller than the diameter of the self - coiling tube 100. The cross - section of the first limiting portion 2120 is generally T - shaped, so as to prevent the self - coiling tube 100 from disengaging from the first flaring member 210.

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

[0053] The second flaring member 220 is provided to further expand the opening of the self - coiling tube 100, so as to adapt to a thicker wire harness. When the self - coiling tube 100 passes through the second flaring member 220, it first passes through the second limiting portion 2220 to maintain the opening state, and then passes through the second guiding portion 2210 to further expand the opening. The second guiding portion 2210 is generally also frustum - shaped.

[0054] Generally, it is impossible to expand the self - coiling tube 100 to the required degree through one - time flaring, otherwise the opening of the self - coiling tube 100 will burst and cannot be restricted from closing by the limiting portion. That is to say, the slope of the guiding portion cannot be too large, nor can the guiding portion be made too long. In this embodiment, through the mutual cooperation of the first flaring member 210 and the second flaring member 220, the purpose of expanding the self - coiling tube 100 to a certain opening degree and avoiding the inability to restrict the closing of the self - coiling tube 100 after opening is achieved.

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

[0056] In this embodiment, the cutting assembly 50 is disposed between the first flaring member 210 and the second flaring member 220, so that neither side of the self - coiling tube 100 that has been cut can automatically close, thus facilitating the next operation.

[0057] In some specific embodiments, the cutting assembly 50 includes a cylinder 510 and a cutter (not shown in the figure). The cylinder 510 is used to drive the cutter to move so as to cut the self - coiling tube 100.

[0058] The cylinder 510 has a large impact force, so that the cutter can cut the self - coiling tube 100 at one time.

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

[0060] Preferably, the first flaring member 210 and the second flaring member 220 can be disassembled from the self - coiling tube threading device of the present invention to match self - coiling tubes 100 of different specifications. And the distance between the first edge stop 310 and the second edge stop 320 can be adjusted to adapt to self - coiling tubes 100 of different specifications.

[0061] In some specific embodiments, a control system and sensors are further included. By detecting the self - coiling tube 100 and the cable with the sensors, it is ensured that the cable can be accurately introduced into the self - coiling tube 100, avoiding misalignment and damage. Specifically, the control system can control the first motor 440, the second motor, the gripper 430, the cylinder 510, etc. The sensors can sense information such as the position and length of the self - coiling tube 100. Through pre - set software, automated operation is achieved.

[0062] In some specific embodiments, an emergency stop button, a protective cover and an alarm system are further included. Among them, the emergency stop button can be pressed in an emergency to stop the machine from running. The protective cover can prevent injury to the operator, and the alarm system can play a role in notifying danger or faults.

[0063] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0064] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
