Description

Technical Field

[0001] The utility model relates to the technical field of tape feeding equipment, in particular to a tape film separation mechanism. Background Art

[0002] In modern automobiles, there are a large number of automotive wiring harnesses. The automotive wiring harness is the network main body of the automotive circuit, connecting the electrical and electronic components of the vehicle and enabling them to function. Without the wiring harness, there would be no automotive circuit. Currently, whether it is a high-class luxury car or an economy-class ordinary car, the form of the wiring harness is basically the same, consisting of wires, connectors, and wrapping tapes. It not only needs to ensure the transmission of electrical signals but also guarantee the reliability of the connected circuit, supply a specified current value to the electrical and electronic components, prevent electromagnetic interference to the surrounding circuits, and eliminate electrical short circuits.

[0003] When producing the wiring harness, usually multiple wires are braided together and then tapes are wound around the outside. During this process, the following phenomena exist:

[0004] One is that the movement is asynchronous when the tape is separated from the tape film;

[0005] The other is that there is a lack of a guiding device during the movement of the tape film, and faults such as blockage are likely to occur.

[0006] The above phenomena result in that the tape feeding equipment cannot synchronously separate the tape and the tape film, affecting the winding efficiency of the wiring harness and having poor practical performance. Content of the Utility Model

[0007] The technical problem that the utility model needs to solve is to provide a tape film separation mechanism to solve the problem that the existing tape feeding equipment cannot synchronously separate the tape and the tape film, affecting the winding efficiency of the wiring harness.

[0008] To solve the above technical problem, the technical solution adopted by the utility model is: a tape film separation mechanism, including a tape roll and a traction member. The traction member is used to provide traction force for the tape, and a damper is arranged on the rotating shaft of the tape roll; on the side of the tape roll away from the traction member, a first guiding part and a second guiding part are arranged. The first guiding part is parallel to the plane where the cross-section of the tape roll is located. The second guiding part is located on the side of the first guiding part away from the tape roll, and the second guiding part is perpendicular to the plane where the cross-section of the tape roll is located. The second guiding part includes a motor, a first rotating rod, and a second rotating rod. The first rotating rod is fixed to the output end of the motor. When the traction member works, the motor drives the tape film to pass through the first guiding part and through the gap between the first rotating rod and the second rotating rod through the first rotating rod.

[0009] Preferably: the traction force of the traction member is greater than the resistance of the damper, and the resistance of the damper is greater than the traction force of the motor.

[0010] Preferably, the resultant force of the traction force of the traction member, the traction force of the motor, and the resistance of the damper is greater than the adhesion force between the tape and the tape film.

[0011] Preferably, the first guiding portion includes at least one third rotating

[0012] rod, and the tape film is rotatably connected to at least one third rotating rod.

[0013] Preferably, the second guiding portion further includes a pressure adjusting member, and both ends of the pressure adjusting member are respectively abutted against the rotating shaft of the second rotating rod.

[0014] Preferably, the pressure adjusting member includes a stopper abutted against both ends of the rotating shaft of the second rotating rod, two springs, a connecting rod, a threaded rod, and a pressing block. The pressing block is disposed above the second rotating rod. A threaded hole is provided at the center of the pressing block, and the threaded rod is threadedly connected to the threaded hole.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides the following embodiments to describe the present utility model in detail:

[0028] Embodiment

[0029] Referring to Figures 1-5 As shown, a tape film separating mechanism includes a tape roll and a traction part 3. The traction part 3 is used to provide traction force for the tape. The installation position of the traction part 3 can be freely adjusted as needed, mainly to provide traction force for the tape. It can be achieved by the rotation of the motor, or by the pulling force generated by the rotation of the wire harness, or by the combination of both. A damper 4 is provided on the rotating shaft of the tape roll. On the one hand, the damper 4 reduces the influence on the tape roll when the tape roll suddenly stops or starts, and plays a role in stabilizing the rotation speed of the tape roll. On the other hand, it prevents the tape film from reversing due to excessive pulling force when the tape film is subjected to a pulling force.

[0030] In the actual production process, if the separated tape film is not collected in time, the tape film may move with the tape or get stuck in the gaps of the equipment. If not dealt with in time, it will cause the tape film to wind around the wire harness together with the tape, or cause the tape film to accumulate, and finally it will also affect the winding efficiency of the wire harness. Therefore, the present application provides a first guiding part 1 and a second guiding part 2 on one side of the tape roll. The first guiding part 1 is parallel to the plane where the cross-section of the tape roll is located. The second guiding part 2 is located on the side of the first guiding part 1 away from the tape roll, and the second guiding part 2 is perpendicular to the plane where the cross-section of the tape roll is located.

[0031] In the above structure, during use, the first guiding portion 1 is parallel to the plane where the cross-section of the tape roll is located. With such a structure, according to the position around the tape roll when the tape and the tape roll are separated, the position of the first guiding portion 1 can be adjusted, as long as it satisfies that the tape film passes through the first guiding portion 1. The second guiding portion 2 is located on the side of the first guiding portion 1 away from the tape roll, and the second guiding portion 2 is perpendicular to the plane where the cross-section of the tape roll is located. The second guiding portion 2 adjusts its corresponding position according to the position of the first guiding portion 1 to satisfy being perpendicular to the first guiding portion 1. That is to say, the adjustment trajectories of the first guiding portion 1 and the second guiding portion 2 are two concentric circles around the tape roll; the positions of the first guiding portion 1 and the second guiding portion 2 can be set as Figure 1 and Figure 2 shown.

[0032] To better achieve the collection of the tape film, a motor 21, a first rotating rod 22, and a second rotating rod 23 are provided on the second guiding portion 2. The first rotating rod 22 is fixed to the output end of the motor 21. During actual use, the traction force of the traction member 3 is set to be greater than the resistance of the damper 4, the resistance of the damper 4 is greater than the traction force of the motor 21, and the resultant force of the traction force of the traction member 3, the traction force of the motor 21, and the resistance of the damper 4 is greater than the adhesion force between the tape and the tape film. When the traction member 3 operates, the tape and the tape film are separated from each other, and the motor 21 drives the tape film to pass through the first guiding portion 1 and through the gap between the first rotating rod 22 and the second rotating rod 23 through the first rotating rod 22.

[0033] With such a structure, through the cooperation of the traction member 3, the damper 4, and the motor 21, the synchronous separation of the tape and the tape film is achieved, and at the same time, the tape film can be better collected, which has good practicability.

[0034] In the above structure, the first guiding portion 1 includes at least one third rotating rod 11, and the tape film is rotationally connected to at least one third rotating rod 11. The number of the third rotating rods 11 is adjusted according to the positional relationship of the first guiding portion 1.

[0035] In actual production, due to different types of tapes used, the material and thickness of the tape film will be different. To better control the traction force provided by the motor 21 and finally achieve the synchronous separation of the tape and the tape film, a pressure adjusting member 24 is further provided on the second guiding portion 2, and both ends of the pressure adjusting member 24 are abutted against the rotating shafts of the second rotating rod 23 respectively.

[0036] Specifically, the pressure adjusting member 24 includes a stopper 241 abutted against both ends of the rotating shaft of the second rotating rod 23, two springs 242, a connecting rod 243, a threaded rod 244, and a pressing block 245. The pressing block 245 is disposed above the second rotating rod 23. A threaded hole is provided at the center of the pressing block 245. The threaded rod 244 is threadedly connected to the threaded hole. One end of the threaded rod 244 is rotatably connected to the connecting rod 243. Both ends of the connecting rod 243 are respectively abutted against the two springs 242. Both of the two springs 242 are abutted above the stopper 241.

[0037] To better adjust the pressure, an indicating disk 246 is provided at the other end of the threaded rod 244. The indicating disk 246 is located above the pressing block 245. A scale bar 247 is provided on the pressing block 245. The scale bar 247 is used to display the moving distance of the threaded rod 244. With such a structure, by rotating the indicating disk 246 to drive the threaded rod 244 to rotate, the distance between the second rotating rod 23 and the first rotating rod 22 can be adjusted, so as to adjust the magnitude of the frictional force received by the tape film, and finally realize the adjustment of the tensile force received by the tape film, ensuring the synchronous separation of the tape and the tape film.

[0038] It should be understood that when rotating the indicating disk to drive the threaded rod to rotate to adjust the distance between the second rotating rod and the first rotating rod, the purpose of adjusting the distance between the second rotating rod and the first rotating rod is to change the frictional force between the tape film and the second rotating rod and the first rotating rod. In the actual process of using and adjusting the pressure, due to the small thickness of the tape film, when the indicating disk drives the threaded rod to adjust, the rotation stroke of the indicating disk is less than half a turn, and the situation where the number of turns of the indicating disk exceeds one week will not occur. Therefore, when rotating the indicating disk to drive the threaded rod to rotate less than half a turn, the relative position between the indicating protrusion on the indicating disk and the scale bar changes, and the distances from both ends of the threaded rod to the pressing block change, so as to display the moving distance of the screw rod.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
