Description

Technical Field

[0001] The invention relates to the technical field of automobile wire harness processing, and in particular to a material tape winding device with a guide structure. Background Art

[0002] As an indispensable component in the automotive power system, the quality of automotive wiring harnesses is directly related to the product stability and safety of the vehicle itself. Automotive wiring harnesses are usually composed of wires, connectors and protective materials. Connectors are also called terminal blocks, which are responsible for connecting wires together. There are many types of connectors. According to the connection method and interface type, they can be divided into plugs, sockets, connectors, etc. The quality and performance of connectors directly affect the reliability and safety of the wiring harness.

[0003] Existing automotive wiring 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 product, which is composed of a flexible strip and pins evenly spaced on the flexible strip. During the manufacturing process of the strip product, a winding device is required, which is used to wind up the strip product to facilitate the subsequent production of wiring harness connectors. However, the existing winding devices on the market generally include a winding roller and a motor for driving the winding roller to rotate. When the winding device is working, it is necessary to first put the winding reel on the winding roller, and then wind one end of the winding material on the winding reel. In this way, as the motor is started, the winding reel 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, which causes the material to be twisted during the winding process due to looseness and vibrations generated during the winding process, resulting in inconsistent insertion directions of the wound material, which seriously affects subsequent processing. On the other hand, as the material is continuously wound, the diameter of the material on the outside of the winding disk will gradually increase, and the output power of the motor is usually constant, that is, the speed of the winding disk is constant, so as the diameter of the material on the outside of the winding disk increases, its winding speed will also increase. If the feeding speed at the material feeding end cannot adapt to the change in the winding speed, it will cause the feeding to be slow and the winding to be fast, and then pull the material and cause damage. To this end, we propose a material belt winding device with a guiding structure to well solve the above-mentioned disadvantages. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 - Fig. 9 A material strip winding device with a guide structure includes a base 100, a winding roller 200 is rotatably provided on the top surface of the base 100, and a guide mechanism 300. The guide mechanism 300 includes a guide plate 301, the guide plate 301 is fixedly arranged on the base 100 and is located on one side of the winding roller 200, and a plurality of guide rollers 302 are rotatably provided on the top surface of the guide plate 301, and the plurality of guide rollers 302 are symmetrically distributed in pairs; specifically, in the present embodiment, there are two pairs of guide rollers 302, that is, four guide rollers, and the material to be wound passes between two guide rollers 302 that are relatively distributed.

[0021] It is worth mentioning that the top surface of the guide plate 301 is also provided with a plurality of staggered strip openings 303, the strip openings 303 are located between the two pairs of guide rollers 302, a slider 304 is slidably connected in the strip openings 303, a winding roller 305 is rotatably provided on the top surface of the slider 304, and both ends of the slider 304 pass through a return spring 306, and the end of the return spring 306 away from the slider 304 is in contact with the inner wall of the strip opening 303. In a natural state, since both ends of the slider 304 have return springs 306, the slider is located in the middle position of the inner side of the strip opening 303.

[0022] In a specific application of this embodiment, the material to be wound needs to pass between several winding rollers 305, such as Figure 2 As shown, when the material winding speed is greater than the material feeding speed, the slider 304 can adapt to the tightness of the material through appropriate displacement, so as not to tear the material.

[0023] This embodiment also includes a positioning disc 400 and a variable diameter wheel assembly 500, wherein the positioning disc 400 is sleeved on the outer side of the winding roller 200, the positioning disc 400 is fixedly connected to the base 100 by a support rod, and a removable fixed sleeve is provided on the outer side of the top of the winding roller 200 with a winding disc 201, and the winding disc 201 is used for winding materials. Specifically, a tightening cap 202 is threadedly connected to the top of the winding roller 200, and the bottom surface of the tightening cap 202 is tightly fitted with the top surface of the winding disc 201. A positioning flange 203 is also provided on the outer side of the winding roller 200, and the bottom surface of the winding disc 201 is tightly fitted with the upper surface of the positioning flange 203. Therefore, when the winding disc 201 needs to be replaced, it is only necessary to remove the tightening cap 202 and then take out the winding disc 201.

[0024] The specific structure of the variable diameter wheel assembly 500 is introduced below: The variable diameter wheel assembly 500 is fixedly mounted 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, which is fixedly mounted on the outer side of the winding roller 200, and the top surface of the positioning ring 501 is provided with a receiving ring groove 502 along its own circumference, and a rotating ring 503 is rotatably arranged in the receiving ring groove 502, and a plurality of driving openings 504 are evenly spaced on the surface of the rotating ring 503, and the driving openings 504 are in an arc shape, and the distances between the two ends of the driving openings 504 and the center of the positioning ring 501 are unequal; a plurality of displacement rods 505 are movably penetrated through the outer surface of the positioning ring 501, and the displacement rods 505 correspond to the driving openings 504 one by one, and the displacement rods 505 are distributed along the radial direction of the positioning ring 501, and a driving column 506 is provided at the inner end of the displacement rod 505, and a belt hoop 507 in the shape of an arc is provided at the outer end of the displacement rod 505, and the driving column 506 is movably embedded in the corresponding driving opening 504. Specifically, the outer wall of the positioning ring 501 is provided with a movable hole (not shown in the figure) for the displacement rod 505 to pass through. When the rotating ring 503 rotates, the cooperation between the driving column 506 and the driving port 504 can indirectly drive the displacement rod 505 to slide along its own length direction.

[0025] In addition, a sliding sleeve 508 is sleeved on the outer side of each displacement rod 505, the sliding sleeve 508 and the displacement rod 505 are slidably matched, and the sliding sleeve 508 and the positioning ring 501 are fixedly connected; the sliding sleeve 508 is fixedly connected to the inner wall of the positioning ring 501, and the function of the sliding sleeve 508 is to enable the displacement rod 505 to slide stably along its own length direction.

[0026] Furthermore, the variable diameter wheel assembly 500 also includes an elastic anti-slip belt 509, which is sleeved on the outside of a plurality of belt hoops 507. In a natural state, the elastic anti-slip belt 509 is in a taut state; the belt hoops 507 are in an arc shape, and the cross-section of the belt hoops 507 is in a U-shape, which serves to prevent the elastic anti-slip belt 509 from falling off.

[0027] like Fig. 9 As shown, a mounting ring 510 is fixedly provided on the inner bottom surface of the receiving ring groove 502, and the mounting ring 510 is arranged coaxially with the positioning ring 501. A driven ring 511 is provided on the inner side of the mounting ring 510 through a bearing rotating sleeve, and the top of the driven ring 511 is fixedly connected to the rotating ring 503. A driven ring gear 512 is fixedly provided on the inner ring of the driven ring 511, and 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 receiving ring groove 502 and is provided with a driving gear 514, which is meshed with the driven ring gear 514. Therefore, by controlling the driving gear 514 to rotate through the servo motor 513, the rotating ring 503 can be driven to rotate synchronously through the driven ring gear 512.

[0028] It should be noted that several belt hoops 507 are spaced apart to form a ring shape, and the elastic anti-skid belt 509 is tensioned and sleeved on the outside of the several belt hoops 507. The elastic anti-skid 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-skid belt 509 can be indirectly controlled.

[0029] Furthermore, the positioning disk 400 is also provided with a driving assembly 600, which 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 arranged 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, and the driving pulley 603 is connected to the variable diameter wheel assembly 500 through a belt 604. That is, the belt 604 is sleeved on the outer side of the driving pulley 603 and the elastic anti-skid belt 509. Therefore, when the driving motor 602 controls the driving pulley 603 to rotate, the variable diameter wheel assembly 500 can be driven to rotate synchronously, thereby controlling the synchronous rotation of the winding disk 201.

[0030] Specifically, the positioning disk 400 is provided with sliding openings 401 distributed along its radial direction, and a moving block 605 is provided on the top surface of the moving frame 601, and the moving block 605 is slidably connected to the sliding opening 401. A tightening spring 606 is also provided in the sliding opening 401, and one end of the tightening spring 606 is fixedly connected to the moving block 605, and the other end is connected to a surface in the sliding opening 401 and close to the center of the positioning disk 400; in a natural state, the tightening spring 606 is in a compressed state. Therefore, the tightening 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.

[0031] 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 of the winding disk 201, and the detection end of the second distance measuring sensor 403 points to the side of the variable diameter wheel assembly 500. The first distance measuring sensor 402 and the second distance measuring sensor 403 are both infrared distance measuring sensors; a controller 515 is also provided on the bottom surface of the positioning ring 501, and 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 also provided on the bottom surface of the positioning ring 501, and the power supply 516 is electrically connected to the servo motor 513 and the controller 515.

[0032] In summary, as the winding work of the winding reel 201 is continuously carried out, the outer diameter of the winding reel 201 is also continuously increasing, and the detection end of the first distance measuring sensor 402 is always aligned with the side of the winding reel 201, which is equivalent to being able to detect the diameter change of the winding reel 201. The first distance measuring sensor 402 transmits the diameter signal of the winding reel 201 to the controller 515 in real time, and the controller 515 controls the servo motor 513 to perform corresponding actions, so that the displacement rod 505 extends outward to increase the diameter of the elastic anti-skid belt 509 to adapt to the diameter change of the winding reel 201, so that the diameter of the elastic anti-skid belt 509 is always close to the material diameter of the winding reel 201.

[0033] As the driving motor 602 works, 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 speed of the driving pulley 603 is always consistent with the outer surface linear speed of the elastic anti-skid belt 509. Since the diameter of the elastic anti-skid belt 509 is close to the diameter of the material on the winding disk 201, it is equivalent to the outer diameter linear speed of the driving pulley 603 being close to the winding speed of the winding disk 201. Therefore, in this embodiment, it is only necessary to keep the power of the driving motor 602 constant so that the outer diameter linear speed of the driving pulley 603 is consistent with the feeding speed of the winding material, so as to ensure that the winding speed is close to the feeding speed, thereby avoiding pulling the winding material.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
