Description

Technical Field

[0001] The present invention relates to the technical field of automotive wire harness processing, and specifically relates to a tape winding device with a guiding structure. Background Art

[0002] As an indispensable component in the automotive power system, the quality of the automotive wire harness is directly related to the product stability and safety of the vehicle itself. The automotive wire harness is usually composed of wires, connectors, and protective materials. The connectors, also known as terminal blocks, are responsible for connecting the wires together. There are various types of connectors, which can be classified into plugs, sockets, connectors, etc. according to different connection methods and interface types. The quality and performance of the connectors directly affect the reliability and safety of the wire harness.

[0003] The existing automotive wire harness connectors can generally be divided into three parts: a housing, an insulator, and a contact body. The contact body is generally a pin, and the initial form of the pin is a strip-shaped product, which is composed of a flexible tape and pins evenly distributed at intervals on the flexible tape. During the specific manufacturing process of this strip-shaped product, a winding device is required to wind up the strip-shaped product to facilitate the subsequent production of wire harness connectors. However, the existing winding devices on the market generally include a winding roller and an electric motor for driving the winding roller to rotate. When this winding device is working specifically, the winding disk needs to be sleeved on the winding roller first, and then one end of the winding material is wound around the winding disk first. In this way, with the start of the electric motor, the winding disk can be driven to rotate, thereby continuously winding the material.

[0004] However, most of the existing winding devices on the market lack a material guiding structure, resulting in the material being distorted during the winding process due to looseness and vibration generated during the winding process, causing the pin directions of the wound material to be inconsistent, seriously affecting subsequent processing. On the other hand, as the material is continuously wound, the diameter of the material on the outer side of the winding disk will gradually increase. The output power of the electric motor is usually constant, that is, the rotation speed of the winding disk is constant. Then, as the diameter of the material on the outer side of the winding disk becomes larger and larger, its winding speed will also become faster and faster. If the feeding speed at the material feeding end cannot adapt to the change in the winding speed, it will cause the situation of slow feeding and fast winding, and then pull the material, causing damage. For this reason, we have proposed a tape winding device with a guiding structure to well solve the above drawbacks. Summary of the Invention

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 - Figure 9 , a tape winding device with a guiding structure, including a base 100, a winding roller 200 is rotatably arranged on the top surface of the base 100, and further includes a guiding mechanism 300. The guiding mechanism 300 includes a guiding plate 301. The guiding plate 301 is fixedly arranged on the base 100 and is located on one side of the winding roller 200. A plurality of guiding rollers 302 are rotatably arranged on the top surface of the guiding plate 301, and the plurality of guiding rollers 302 are symmetrically distributed in pairs; specifically in this embodiment, there are two pairs of guiding rollers 302, that is, four in total. The material to be wound passes through between two relatively distributed guiding rollers 302.

[0038] It is worth mentioning that a plurality of strip-shaped openings 303 are also provided on the top surface of the guiding plate 301 and are distributed in a staggered manner. The strip-shaped openings 303 are located between the two pairs of guiding rollers 302. A slider 304 is slidably connected in the strip-shaped opening 303. A winding roller 305 is rotatably arranged on the top surface of the slider 304, and both ends of the slider 304 are respectively connected by a return spring 306. The ends of the return spring 306 away from the slider 304 are respectively abutted against the inner walls of the strip-shaped opening 303. In the natural state, since both ends of the slider 304 are provided with return springs 306, the slider is located at the middle position inside the strip-shaped opening 303.

[0039] In specific applications of this embodiment, it is necessary to make the material to be wound pass between several winding rollers 305. As Figure 2 shown, when the winding speed of the material is greater than the feeding speed, the slider 304 can be appropriately displaced to adapt to the tightness of the material, so as not to damage the material.

[0040] This embodiment further includes a positioning disk 400 and a variable-diameter wheel assembly 500. Among them, the positioning disk 400 is sleeved on the outer side of the winding roller 200, and the positioning disk 400 is fixedly connected to the base 100 through a support rod. A winding disk 201 is detachably and fixedly sleeved on the outer side of the top of the winding roller 200, and the winding disk 201 is used for winding the material. Specifically, a tightening cap 202 is threadedly connected to the top end of the winding roller 200, and the bottom surface of the tightening cap 202 is in close contact with the top surface of the winding disk 201. A positioning flange 203 is further provided on the outer side of the winding roller 200, and the bottom surface of the winding disk 201 is in close contact with the upper surface of the positioning flange 203. Therefore, when the winding disk 201 needs to be replaced, only the tightening cap 202 needs to be removed, and then the winding disk 201 can be taken out.

[0041] The following introduces the specific structure of the variable-diameter wheel assembly 500:

[0042] The variable-diameter wheel assembly 500 is fixedly sleeved on the outer side of the winding roller 200 and is located below the positioning disk 400; the variable-diameter wheel assembly 500 includes a positioning ring 501, and the positioning ring 501 is fixedly sleeved on the outer side of the winding roller 200. An accommodating ring groove 502 is formed in a circle along the circumferential direction of the top surface of the positioning ring 501, and a rotating ring 503 is rotatably arranged in the accommodating ring groove 502. A plurality of driving ports 504 are evenly spaced on the surface of the rotating ring 503. The driving ports 504 are arc-shaped, and the distances from the two ends of the driving ports 504 to the center position of the positioning ring 501 are not equal; a plurality of displacement rods 505 are movably penetrated through the outer surface of the positioning ring 501. The displacement rods 505 correspond to the driving ports 504 one by one. The displacement rods 505 are distributed along the radial direction of the positioning ring 501. A driving column 506 is provided at the inner end of the displacement rod 505, and a belt hoop 507 in an arc shape is provided at the outer end of the displacement rod 505. The driving column 506 is movably embedded in the corresponding driving port 504. Specifically, a moving hole (not shown in the figure) for the displacement rod 505 to penetrate is formed in the outer wall of the positioning ring 501. When the rotating ring 503 rotates, due to the cooperation between the driving column 506 and the driving port 504, the displacement rod 505 can be indirectly driven to slide along its own length direction.

[0043] In addition, sliding sleeves 508 are sleeved on the outer sides of the plurality of displacement rods 505. The sliding sleeves 508 are slidably matched with the displacement rods 505, and the sliding sleeves 508 are fixedly connected to the positioning ring 501; the sliding sleeves 508 are fixedly connected to the inner wall of the positioning ring 501. The function of the sliding sleeves 508 is to enable the displacement rods 505 to slide stably along their own length directions.

[0044] Furthermore, the diameter-changing wheel assembly 500 further includes an elastic anti-slip belt 509. The elastic anti-slip belt 509 is sleeved on the outer sides of a plurality of belt hoops 507. In the natural state, the elastic anti-slip belt 509 is in a taut state; the belt hoops 507 are arc-shaped, and the cross-section of the belt hoops 507 is in a U-shape, and its function is to prevent the elastic anti-slip belt 509 from falling off.

[0045] As Figure 9 shown, an installation ring 510 is fixedly provided on the inner bottom surface of the accommodation ring groove 502. The installation ring 510 and the positioning ring 501 are arranged on the same central axis. A driven ring 511 is rotatably sleeved on the inner side of the installation ring 510 through a bearing. The top end of the driven ring 511 is fixedly connected to the rotating ring 503. A driven gear ring 512 is fixedly sleeved on the inner ring of the driven ring 511. A servo motor 513 is provided on the bottom surface of the positioning ring 501. The output shaft of the servo motor 513 extends into the interior of the accommodation ring groove 502 and is provided with a driving gear 514. The driving gear 514 meshes with the driven gear ring 512. Therefore, by controlling the rotation of the driving gear 514 by the servo motor 513, the rotating ring 503 can be driven to rotate synchronously through the driven gear ring 512.

[0046] It should be noted that a plurality of belt hoops 507 are spaced apart to form a ring shape, and the elastic anti-slip belt 509 is tightly sleeved on the outer sides of the plurality of belt hoops 507. The elastic anti-slip belt 509 is made of rubber material. When the servo motor 513 controls the rotation of the rotating ring 503, the diameter change of the elastic anti-slip belt 509 can be indirectly controlled.

[0047] Furthermore, a driving assembly 600 is further provided on the positioning disk 400. The driving assembly 600 includes a moving frame 601, a driving motor 602 and a driving pulley 603. The moving frame 601 is movably connected to the positioning disk 400. The driving motor 602 is fixedly provided on the bottom surface of the moving frame 601. The output shaft of the driving motor 602 is coaxially connected to the driving pulley 603. The driving pulley 603 and the diameter-changing wheel assembly 500 are connected by a belt 604. That is, the belt 604 is sleeved on the outer sides of the driving pulley 603 and the elastic anti-slip belt 509. Therefore, when the driving motor 602 controls the rotation of the driving pulley 603, the diameter-changing wheel assembly 500 can be synchronously driven to rotate, so as to control the synchronous rotation of the winding disk 201.

[0048] Specifically, a sliding opening 401 is also formed in the positioning disk 400 along its radial direction. A moving block 605 is provided on the top surface of the moving frame 601. The moving block 605 is slidably connected to the sliding opening 401. A pressing spring 606 is further provided in the sliding opening 401. One end of the pressing spring 606 is fixedly connected to the moving block 605, and the other end thereof is connected to a surface in the sliding opening 401 and close to the center of the positioning disk 400. In the natural state, the pressing spring 606 is in a compressed state. Therefore, the pressing spring 606 has a force to push the moving block 605 outward, so that the belt 604 is always in a tensioned state to avoid slipping.

[0049] In another embodiment of the present application, a first distance measuring sensor 402 is provided on the top surface of the positioning disk 400, and a second distance measuring sensor 403 is provided on the bottom surface of the positioning disk 400. The detection end of the first distance measuring sensor 402 points to the side surface of the winding disk 201, and the detection end of the second distance measuring sensor 403 points to the side surface of the diameter-changing wheel assembly 500. Both the first distance measuring sensor 402 and the second distance measuring sensor 403 adopt infrared distance measuring sensors. A controller 515 is further provided on the bottom surface of the positioning ring 501. The signal output ends of the first distance measuring sensor 402 and the second distance measuring sensor 403 are both connected to the controller 515, and the signal output end of the controller 515 is connected to the servo motor 513. In addition, a power supply 516 is provided on the bottom surface of the positioning ring 501. The power supply 516 is electrically connected to the servo motor 513 and the controller 515.

[0050] In summary, as the winding work of the winding disk 201 continues, the outer diameter of the winding disk 201 is also constantly increasing. The detection end of the first distance measuring sensor 402 always aligns with the side surface of the winding disk 201, which is equivalent to being able to detect the diameter change of the winding disk 201. The first distance measuring sensor 402 transmits the diameter signal of the winding disk 201 to the controller 515 in real time. The controller 515 then controls the servo motor 513 to perform corresponding actions, so as to make the displacement rod 505 extend outward to increase the diameter of the elastic anti-slip belt 509 to adapt to the diameter change of the winding disk 201, so that the diameter of the elastic anti-slip belt 509 is always close to the material diameter of the winding disk 201.

[0051] With the operation of the driving motor 602, it can drive the positioning ring 501 and the driving pulley 603 to rotate together. Since the driving pulley 603 and the positioning ring 501 are driven by a belt, the outer diameter linear velocity of the driving pulley 603 is always consistent with the outer surface linear velocity of the elastic anti-slip belt 509. And because the diameter of the elastic anti-slip belt 509 is close to the diameter of the material on the winding disc 201, therefore, it is equivalent that the outer diameter linear velocity of the driving pulley 603 is close to the winding speed of the winding disc 201. So in this embodiment, only need to keep the power of the driving motor 602 constant, so that the outer diameter linear velocity of the driving pulley 603 is consistent with the feeding speed of the winding material, then it can ensure that the winding speed is close to the feeding speed, thereby avoiding pulling the winding material.

[0052] 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 term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
