Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and specifically relates to a cable feeding mechanism. Background Technology

[0002] Cable processing typically refers to the further processing and assembly of standard cables according to the specific needs of customers or projects, in order to produce ready-to-use wire harnesses, cable assemblies, or connectors. The wire release mechanism is the starting point and source of continuous material processing equipment such as cables, wires, optical fibers, and ropes. Its core task is to continuously, smoothly, and controllably release the material on the coil (spool / boob) into the subsequent production process. Its performance directly determines the stability, tension, and product quality of the entire production process.

[0003] The existing wire feeding mechanism uses a motor to drive the wire reel to rotate. The speed of the reel is matched with the speed of subsequent equipment through a control system. By adjusting the motor speed in real time, the wire feeding speed is made slightly faster than the traction speed, thereby maintaining a constant, small tension to feed the wire during the cable processing. However, in actual use, because the tension adjustment mechanism for the cable is relatively simple, when feeding some tension-sensitive products, the cable may still be stretched and deformed due to excessive tension, or loosened and knotted due to insufficient tension, which will affect the physical structure and electrical performance of the cable and cause certain losses. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a cable feeding mechanism that can achieve precise tension control through a multi-stage linkage adjustment mechanism. By dynamically adjusting the bending degree of the cable wound around it, real-time and fine tension fine-tuning can be performed. This composite control strategy can effectively prevent the cable from being stretched and deformed due to excessive tension, or from becoming loose and knotted due to insufficient tension, thus ensuring that the physical structure and electrical performance of the cable are not damaged from the root.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wire feeding mechanism, including a wire feeding frame, two mounting frames symmetrically distributed about the vertical center of the wire feeding frame are fixedly arranged inside the wire feeding frame, and two mounting seats symmetrically distributed about the vertical center of the wire feeding frame are fixedly arranged between the mounting frames. Each of the upper surfaces of the mounting base is fixedly equipped with a slide cylinder 1, and each of the slide cylinder 1 has a slide rod 1 slidably mounted inside it. Each of the slide rod 1 has a support 1 fixedly mounted at its top. An adjusting roller 1 is rotatably mounted between the two supports 1. Each of the lower surfaces of the mounting base is fixedly equipped with a slide cylinder 2, and each of the slide cylinder 2 has a slide rod 2 slidably mounted inside it. Each of the slide rod 2 has a support 2 fixedly mounted at its bottom. An adjusting roller 2 is rotatably mounted between the two supports 2. Slide cylinder 1 and slide cylinder 2 are centrally symmetrical about the transverse central axis of the mounting base. Each of the four corners of the lower surface of the wire feeding frame is fixedly equipped with a fixing plate, and each fixing plate has a fixing hole in its center.

[0006] As a further improvement of this utility model, a connecting pipe is fixedly arranged between the mounting bases, and a guide roller is rotatably arranged on the outer arc surface of the connecting pipe. A linkage shaft is rotatably arranged between the two mounting bases and the middle of the connecting pipe. Two gears symmetrically distributed at the vertical center of the wire feeding frame are fixedly sleeved on the outer arc surface of the linkage shaft. A rack plate is fixedly arranged at the bottom end of slide rod one and the top end of slide rod two, and the rack plate is respectively meshed with the adjacent gear. A storage cylinder one is fixedly arranged on the lower surface of the mounting base, and a storage cylinder two is fixedly arranged on the upper surface of the mounting base. The storage cylinder one and the storage cylinder two are respectively installed in conjunction with the adjacent rack plate.

[0007] As a further improvement of this utility model, a control box is fixedly installed between the mounting brackets. Inside the control box, a worm gear is rotatably installed via a rotating shaft. A worm is rotatably installed on the lower side inside the control box. The worm is meshed with the worm gear. A second servo motor is installed on the outside of the control box. The output shaft of the second servo motor is fixed to the worm via a coupling.

[0008] As a further improvement of this utility model, two mounting plates are fixedly installed inside the wire feeding frame, symmetrically distributed around the vertical center of the wire feeding frame. Two guide rails are fixedly installed between the two mounting plates, symmetrically distributed around the horizontal center of the wire feeding frame. A wire guide plate is slidably installed between the two guide rails. A wire guide hole is opened in the middle of the wire guide plate. An electric push rod II is fixedly installed in the middle of one side of the mounting plate. The telescopic end of the electric push rod II is connected and fixed to the mounting plate.

[0009] As a further improvement of this utility model, the wire feeding frame is internally fixedly equipped with four slide rails, and a lifting platform is slidably arranged between the four slide rails. Rotating sleeves are rotatably arranged on both inner walls of the lifting platform. The wire feeding wheel is detachably installed between two rotating sleeves by bolts. A servo motor is arranged on the outer side of the lifting platform. The output shaft of the servo motor is fixed to the adjacent rotating sleeve by a coupling. An electric push rod is fixedly arranged on the upper surface of the wire feeding frame. The telescopic end of the electric push rod is connected and fixed to the lifting platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, precise tension control is achieved through a multi-stage linkage adjustment mechanism. On one hand, the electric push rod adjusts the initial tension of the cable by raising and lowering the overall height of the cable feeding wheel. On the other hand, the servo motor drives the worm gear and worm wheel, which ultimately drive the adjusting rollers to move in opposite directions or away from each other through the meshing of the gear and rack, dynamically adjusting the bending degree of the cable wound around them. This allows for real-time and fine-tuning of the tension. This composite control strategy effectively prevents the cable from being stretched and deformed due to excessive tension or from becoming loose and knotted due to insufficient tension, ensuring that the physical structure and electrical performance of the cable are not damaged from the source.

[0011] Secondly, the entire process, from wire feeding and guiding to tension adjustment, is automated. Servo motor one drives the wire feeding wheel to rotate, serving as the main power source for wire feeding; electric push rod two controls the horizontal reciprocating sliding of the guide plate, providing guidance for the wire exit. All these actions are precisely executed by the motor and electric push rod, significantly reducing the intensity and difficulty of manual operation, minimizing tension fluctuations caused by human factors, and making the wire feeding process smooth, continuous, and efficient.

[0016] like Figure 2 , 4 As shown, the device includes a wire feeding frame 101, with two mounting frames 201 symmetrically distributed around the vertical center of the wire feeding frame 101 fixedly installed inside the wire feeding frame 101, and two mounting bases 202 symmetrically distributed around the vertical center of the wire feeding frame 101 fixedly installed between the mounting frames 201.

[0017] like Figure 3 , 4 As shown, a connecting pipe 213 is fixedly installed between the mounting bases 202. A guide roller 215 is rotatably installed on the outer arc surface of the connecting pipe 213. A linkage shaft 214 is rotatably installed between the middle of the two mounting bases 202 and the connecting pipe 213. Two gears 216 symmetrically distributed at the vertical centers of the wire feeding frames 101 are fixedly sleeved on the outer arc surface of the linkage shaft 214. A rack plate 217 is fixedly installed at the bottom end of the first slide rod 204 and the top end of the second slide rod 209. The rack plate 217 meshes with the adjacent gear 216 respectively. A storage cylinder is fixedly installed on the lower surface of the mounting bases 202. 207. A second storage cylinder 212 is fixedly installed on the upper surface of the mounting base 202. The first storage cylinder 207 and the second storage cylinder 212 are respectively installed in conjunction with the adjacent rack plate 217. A control box 301 is fixedly installed between the mounting brackets 201. A worm gear 302 is rotatably installed inside the control box 301 via a rotating shaft. A worm 303 is rotatably installed on the lower side inside the control box 301. The worm 303 is meshed with the worm gear 302. A second servo motor 304 is installed on the outside of the control box 301. The output shaft of the second servo motor 304 is fixed to the worm 303 via a coupling.

[0018] like Figure 1 ,2 As shown, two mounting plates 405 are fixedly installed inside the wire feeding frame 101, symmetrically distributed around the vertical center of the wire feeding frame 101. Two guide rails 401 are fixedly installed between the two mounting plates 405, symmetrically distributed around the horizontal center of the wire feeding frame 101. A guide plate 402 is slidably installed between the two guide rails 401. A guide hole 404 is opened in the middle of the guide plate 402. An electric push rod 403 is fixedly installed in the middle of one side of the mounting plate 405. The telescopic end of the electric push rod 403 is connected and fixed to the mounting plate 405.

[0019] like Figure 1 , 2 As shown, four slide rails 103 are fixedly installed inside the wire feeding frame 101, and a lifting platform 104 is slidably arranged between the four slide rails 103. Rotating sleeves are rotatably installed on both inner walls of the lifting platform 104. The wire feeding wheel 105 is detachably installed between two rotating sleeves by bolts. A servo motor 107 is installed on the outer side of the lifting platform 104. The output shaft of the servo motor 107 is fixed to the adjacent rotating sleeve by a coupling. An electric push rod 106 is fixedly installed on the upper surface of the wire feeding frame 101. The telescopic end of the electric push rod 106 is connected and fixed to the lifting platform 104.

[0020] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, fixing plates 102 are fixedly installed at the four corners of the lower surface of the wire feeding frame 101, and fixing holes are opened in the middle of the fixing plates 102.

[0021] In use, the wire feeding wheel 105 is moved between the two rotating sleeves, and then the bolts are tightened with external tools to fix the wire feeding wheel 105 between the two rotating sleeves. Then, the cable end of the wire feeding wheel 105 passes sequentially around the upper adjusting roller 206, the middle guide roller 215, and the lower adjusting roller 211, and then passes through the wire hole 404 in the middle of the wire guide plate 402 and connects to the external processing device. Then, the servo motor 107 is controlled to run, so that the output shaft of the servo motor 107 drives the rotating sleeve connected to it to rotate, which in turn drives the wire feeding wheel 105 to rotate to achieve wire feeding. During the cable laying process, the electric push rod 403 is controlled to move, so that the telescopic end of the electric push rod 403 drives the wire plate 402 connected to it to slide linearly back and forth between the two guide rails 401, thereby facilitating the horizontal guidance and adjustment of the cable laid from the middle of the wire plate 402. The electric push rod 106 is controlled to operate, so that the telescopic end of the electric push rod 106 drives the lifting platform 104 connected to it to slide between the four slide rails 103, so that the lifting platform 104 drives the wire feeding wheel 105 installed on it to rise or fall, thereby controlling the cable tension released from the wire feeding wheel 105 and ensuring that the cable tension is consistent. Then, the servo motor 304 is controlled to run, causing its output shaft to drive the worm gear 303 connected to it to rotate. This, in turn, through the meshing relationship between the worm gear 303 and the worm wheel 302, causes the shaft containing the worm wheel 302 to rotate. This rotation then causes the linkage shaft 214 to rotate, which in turn causes the gears 216 fixed at both ends of the outer arc surface of the linkage shaft 214 to rotate. During the rotation of the gears 216, through the meshing relationship between the gears 216 and the rack plate 217, the rack plate 217 moves, causing the upper and lower rack plates 217 to move towards each other or away from each other. This, in turn, causes the slide rods 204 and 209 connected to the rack plate 217 to move, causing them to move towards each other or away from each other. The direction of movement causes the adjusting roller 206 installed between slide rod 204 and the adjusting roller 211 installed between slide rod 209 to move, causing the upper adjusting roller 206 and the lower adjusting roller 211 to move towards each other or away from each other, adjusting the distance between the adjusting roller 206 and the adjusting roller 211, and further adjusting the tension of the cable wound between the adjusting roller 206 and the adjusting roller 211. Furthermore, through precise tension control during the unwinding process, it can ensure that the cable maintains a constant and appropriate tension, preventing the cable from being stretched thin or deformed, or from becoming knotted due to slack. This stable and reliable tension control ensures that the cable tension remains consistent with the next stage of processing equipment during large-scale unwinding.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
