Description

Technical Field

[0001] This invention relates to the field of stranding equipment, and more specifically to a dual-station stranding equipment. Background Technology

[0002] Currently, wire harnesses, consisting of at least two wires used for signal transmission, are widely used in industries such as trams. To reduce interference in signal transmission, it is often necessary to twist the wires in the harness.

[0003] With the continuous development of technology, although wire stranding equipment that can replace manual stranding has recently emerged in the industry, the process still requires operators to manually cut the wire bundle, then fix one end of the cut wire bundle to the rotating clamping device of the stranding equipment, and then fix the other end of the wire bundle to the stranding mating clamping device. The rotating clamping device then twists the wire bundle into a braid shape, thus completing the stranding process. However, the stranding process still requires operators to manually cut the wire bundle and transfer and fix both ends of the cut wire bundle to the rotating clamping device and the stranding mating clamping device, resulting in a large workload for operators and low stranding efficiency during mass production of wire bundles, thus failing to meet industry requirements. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a dual-station stranding device that can pull wire bundles onto a rotating clamping device and cut wire bundles, thereby reducing the involvement of operators, reducing the workload of operators, and improving the efficiency of stranding.

[0005] The objective of this invention is achieved through the following technical solution:

[0008] The dual-station stranding equipment includes two stranding processing lines, with the wire harness traction and transfer device located between the two lines. The wire harness traction and transfer device includes two clamping seats corresponding to each of the two stranding processing lines. A second driving device is used to drive both clamping seats to translate along the width of the horizontal seat towards the lateral driving device of the corresponding stranding processing line, and also to drive both clamping seats to translate along the width of the horizontal seat away from the lateral driving device of the corresponding stranding processing line. Each clamping seat is equipped with a pneumatic clamp. The dual-station stranding equipment also includes two unwinding devices corresponding to each of the two stranding processing lines, the unwinding devices being used to transfer the wire harness towards the corresponding stranding processing line.

[0009] The second driving device includes a first transmission screw rotatably mounted on a support and extending along the width direction of the transverse support, a first screw drive mechanism mounted on the support and used to drive the first transmission screw to rotate, a first screw nut, and a second screw nut; both clamp seats are movably mounted on the support; the first transmission screw includes a first threaded section and a second threaded section, the thread direction of the first threaded section being opposite to the thread direction of the second threaded section; the first screw nut is fitted onto the first threaded section and fixed to the bottom of one of the clamp seats; the second screw nut is fitted onto the second threaded section and fixed to the bottom of the other clamp seat.

[0010] The first transmission screw further includes an installation section disposed between the first threaded section and the second threaded section; the first screw drive mechanism includes a first drive motor whose body is fixed on a bearing seat, and a transmission component for transmission between the output shaft of the first drive motor and the installation section.

[0011] The transmission assembly includes a driven bevel gear fixed on the mounting section and a driving bevel gear fixed on the output shaft of the first drive motor and meshing with the driven bevel gear.

[0015] The rotary drive device includes a third drive motor and a fixed base fixed on the output shaft of the third drive motor, and the rotary clamping device is disposed on the fixed base.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention provides a dual-station stranding equipment, which employs a stranding processing line, an unwinding device, and a wire harness traction and transfer device. The stranding processing line is combined with a rotary clamping device, a rotary drive device, a first stranding-cooperation clamping device, a second stranding-cooperation clamping device, an opening and closing mechanism, a cutting device, a longitudinal drive device, a transverse seat, a transverse drive device, and a rear clamping device.

Detailed Implementation

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] like Figure 1-8As shown, a dual-station stranding equipment includes a stranding processing line 100, an unwinding device 210, and a wire harness traction and transfer device 300. The stranding processing line 100 includes a rotary clamping device 110 for clamping the wire harness, a rotary drive device 120 for driving the rotary clamping device 110 to rotate, a transverse sliding seat 130 opposite to and located behind the rotary clamping device 110, a first stranded wire mating clamping device 140 mounted on the transverse sliding seat 130 for clamping the wire harness, a second stranded wire mating clamping device 150 mounted on the transverse sliding seat 130 for clamping the wire harness, an opening and closing mechanism 160 mounted on the transverse sliding seat 130 for controlling the synchronous opening and closing of the first stranded wire mating clamping device 140 and the second stranded wire mating clamping device 150, a cutting device 171 for cutting the wire harness, a longitudinal drive device 180 mounted on the transverse sliding seat 130, and a transverse seat 19. 4. A transverse drive device 190 is mounted on the transverse seat 194, and a rear clamping device 200 is located behind the transverse shift seat 130; the wire harness traction and transfer device 300 is used to clamp the wire harness and pull the wire harness between the first stranded wire mating clamping device 140 and the rotary clamping device 110; the longitudinal drive device 180 is located between the first stranded wire mating clamping device 140 and the second stranded wire mating clamping device 150; the transverse drive device 190 is used to drive the transverse shift seat 130 to translate along the length direction of the transverse seat 194 between the rear clamping device 200 and the rotary clamping device 110; the longitudinal drive device 180 is used to drive the shearing device 171 to translate along the width direction of the transverse seat 194; the unwinding device 210 is located behind the rear clamping device 200; the unwinding device 210 is used to wind the power wire harness onto it and to transmit the wire harness toward the stranded wire processing line 100.

[0029] In use, the wire harness is wound onto the unwinding device 210. The wire harness output from the unwinding device 210 is clamped onto the rear clamping device 200. Then, the transverse drive device 190 drives the transverse sliding seat 130 to move towards the rear clamping device 200. The first twisted wire clamping device 140 and the second twisted wire clamping device 150 clamp the end of the wire harness that is exposed outside the rear clamping device 200. After that, the rear clamping device 200 is opened, and the transverse drive device 190 drives the transverse sliding seat 130 to move towards the rotary clamping device 110. As the transverse sliding seat 130 moves towards the rotary clamping device 110, it pulls the wire harness to move. The unwinding device 210 moves under the traction action. The wire harness is unwound and transported toward the stranding processing line 100. After the transverse carrier 130 moves into position, the wire harness traction and transfer device 300 clamps the end of the wire harness exposed outside the first stranding mating clamping device 140. Then, the first stranding mating clamping device 140 and the second stranding mating clamping device 150 are in the open state. The wire harness traction and transfer device 300 then pulls the end of the wire harness onto the rotary clamping device 110. During this process, the unwinding device 210 simultaneously unwinds the wire harness under traction force to transport it toward the stranding processing line 100. The rotary clamping device 110 then clamps the end of the wire harness pulled by the wire harness traction and transfer device 300. The first stranding mating clamping device... 140, the second twisted wire clamping device 150, and the rear clamping device 200 close and clamp the wire bundle. Then, the longitudinal drive device 180 drives the cutting device 171 to move, and the cutting device 171 cuts the wire bundle. At this time, the two ends of the cut wire bundle are respectively clamped on the rotary clamping device 110 and the first twisted wire clamping device 140, so that it is not necessary to manually move the two ends of the cut wire bundle to the rotary clamping device 110 and the first twisted wire clamping device 140, nor is it necessary to manually cut the wire bundle. Then, the rotary drive device 120 drives the rotary clamping device 110 to rotate, and the cut wire bundle is twisted as the rotary clamping device 110 rotates. During this process, the transverse drive device 190 drives the wire bundle to move. The moving transverse seat 130 moves accordingly towards the rotating clamping device 110 to ensure that the wire harness is not broken, thus completing the wire harness stranding. After the wire harness stranding is completed, the stranded wire harness is removed by an external unloading device. Then, the first stranding clamping device 140 and the second stranding clamping device 150 are opened. The transverse drive device 190 drives the transverse seat 130 to move towards the rear clamping device 200. The first stranding clamping device 140 clamps the end of the wire harness that is exposed outside the second stranding clamping device 150. The process continues to process the next section of the wire harness in the same manner. Therefore, the present invention provides a dual-station stranding device.This system employs a stranding processing line 100 and a wire harness traction and transfer device 300. The stranding processing line 100 is integrated with a rotary clamping device 110, a rotary drive device 120, a first stranded wire mating clamping device 140, a second stranded wire mating clamping device 150, an opening and closing mechanism 160, a cutting device 171, a longitudinal drive device 180, a transverse seat 194, a transverse drive device 190, and a rear clamping device 200. This allows the first stranded wire mating clamping device 140 and the second stranded wire mating clamping device 150 to move and clamp the wire harness along with the transverse seat 194. The wire harness can then be pulled onto the rotary clamping device 110 by the wire harness traction and transfer device 300, and simultaneously cut. This eliminates the need for operators to manually cut the wire harness and transfer the cut ends to the rotary clamping device 110 and the stranded wire mating clamping device, reducing operator involvement, workload, and improving stranding processing efficiency.

[0030] The wire harness traction and transfer device 300 includes a support 310, a first drive device 320 for driving the support 310 to translate along the length direction of the transverse support 194, a clamp seat 330, a second drive device 340 mounted on the support 310, and a pneumatic clamp 350 mounted on the clamp seat 330 for clamping the wire harness; the second drive device 340 is used to drive the clamp seat 330 to translate along the width direction of the transverse support 194 towards the transverse drive device 190, and also to drive the clamp seat 330 to translate along the width direction of the transverse support 194 away from the transverse drive device 190. After the first stranded wire clamping device 140 and the second stranded wire clamping device 150 clamp the wire harness and move it into place with the transverse sliding seat 130, the first drive device 320 of the wire harness traction and transfer device 300 drives the bearing seat 310 to translate along the length direction of the transverse seat 194 to be close to the transverse sliding seat 130. Then, the second drive device 340 drives the clamp seat 330 to translate along the width direction of the transverse seat 194 towards the transverse drive device 190. Then, the pneumatic clamp 350 clamps the end of the wire harness that is exposed outside the first stranded wire clamping device 140, and then the second drive device 350 clamps the end of the wire harness that is exposed outside the first stranded wire clamping device 140. A drive device 320 drives the support base 310 to translate along the length of the transverse base 194 towards the rotary clamping device 110. When the pneumatic clamp 350 moves to the corresponding rotary clamping device 110, the rotary clamping device 110 clamps the end of the wire harness that is exposed outside the pneumatic clamp 350. Then, the pneumatic clamp 350 opens. A second drive device 340 drives the clamp base 330 to translate along the width of the transverse base 194 away from the transverse drive device 190 to avoid interference of the pneumatic clamp 350 with the stranded wires of the wire harness when the rotary clamping device 110 rotates. By adopting the above structure for the wire harness traction and transfer device 300, it is convenient to traction the wire harness between the first stranded wire clamping device 140 and the rotary clamping device 110, and it is also convenient for installation.

[0031] The dual-station stranding equipment includes two stranding processing lines 100, and the wire harness traction and transfer device 300 is located between the two stranding processing lines 100. The wire harness traction and transfer device 300 includes two clamp seats 330 that correspond one-to-one with the two stranding processing lines 100. The second driving device 340 is used to drive the two clamp seats 330 to translate along the width direction of the horizontal seat 194 towards the horizontal driving device 190 of the corresponding stranding processing line 100, and also to drive the two clamp seats 330 to translate along the width direction of the horizontal seat 194 away from the horizontal driving device 190 of the corresponding stranding processing line 100. Each clamp seat 330 is equipped with a pneumatic clamp 350. By adopting the above structure, a twisted-pair workstation can be formed to further save time, improve twisting processing efficiency, and allow the two twisted-pair processing lines 100 to share the wire harness traction and transfer device 300, thereby reducing the number of wire harness traction and transfer devices 300 required and lowering costs. The dual-station twisting equipment includes two unwinding devices 210 corresponding to each of the two twisted-pair processing lines 100, the unwinding devices 210 being used to transfer the wire harness toward the corresponding twisted-pair processing line 100.

[0032] The second drive device 340 includes a first transmission screw 341 rotatably mounted on the support 310 and extending along the width direction of the transverse seat 194, a first screw drive mechanism 360 mounted on the support 310 and used to drive the first transmission screw 341 to rotate, a first screw nut 342, and a second screw nut 343; both clamp seats 330 are movably mounted on the support 310; the first transmission screw 341 includes a first threaded section and a second threaded section, the thread direction of the first threaded section being opposite to the thread direction of the second threaded section; the first screw nut 342 is fitted onto the first threaded section and fixed to the bottom of one of the clamp seats 330; the second screw nut 343 is fitted onto the second threaded section and fixed to the bottom of the other clamp seat 330. In use, the first lead screw 341 is driven to rotate forward by the first lead screw drive mechanism 360, which causes one of the clamping seats 330, together with the first lead screw nut 342, to move to the right. This causes the pneumatic clamp 350 on the clamping seat 330 to move towards the lateral drive device 190, which is closer to the corresponding stranding line 100 (i.e., the right-side stranding line 100). During this process, the other clamping seat 330, together with the second lead screw nut 343, moves to the left, causing the pneumatic clamp 350 on the clamping seat 330 to move towards the lateral drive device 190, which is closer to the corresponding stranding line 100 (i.e., the left-side stranding line 100). Translation: The first lead screw 341 is driven to rotate in the opposite direction by the first lead screw drive mechanism 360, thereby causing one of the clamp seats 330, together with the first lead screw nut 342, to move to the left. This causes the pneumatic clamp 350 on the clamp seat 330 to translate away from the lateral drive device 190 of the corresponding stranding line 100 (i.e., the right-side stranding line 100). During this process, the other clamp seat 330, together with the second lead screw nut 343, moves to the right, causing the pneumatic clamp 350 on the clamp seat 330 to translate away from the lateral drive device 190 of the other stranding line 100 (i.e., the left-side stranding line 100). By adopting the above structure for the second drive device 340, it is possible to drive both clamp seats 330 to translate along the width direction of the transverse seat 194 towards or away from the lateral drive device 190 of the corresponding stranding line 100, while also reducing costs.

[0033] The first lead screw 341 further includes a mounting section disposed between the first threaded section and the second threaded section; the first lead screw drive mechanism 360 includes a first drive motor 361 whose body is fixed on the support base 310, and a transmission assembly for transmitting power between the output shaft of the first drive motor 361 and the mounting section. The transmission assembly includes a driven bevel gear 362 fixed on the mounting section and a driving bevel gear 363 fixed on the output shaft of the first drive motor 361 and meshing with the driven bevel gear 362. In use, the first drive motor 361 operates, driving the driving bevel gear 363 to rotate, which in turn drives the first lead screw 341 to rotate via the driven bevel gear 362.

[0034] The rotary drive device 120 includes a third drive motor 121 and a fixed base 122 fixed on the output shaft of the third drive motor 121. The rotary clamping device 110 is mounted on the fixed base 122. In use, the fixed base 122 can be rotated by the output shaft of the third drive motor 121, thereby driving the rotary clamping device 110 to rotate.

[0035] The pneumatic clamp 350 is provided with an actuating component 370 for opening the rotary clamping device 110 when the clamp seat 330 moves toward the direction of approaching the rotary clamping device 110. When the first driving device 320 drives the bearing seat 310 together with the clamp seat 330 and the pneumatic clamp 350 toward the direction of approaching the rotary clamping device 110, the actuating component 370 can be used to open the rotary clamping device 110 so that the end of the wire harness exposed outside the pneumatic clamp 350 can be extended into the opened rotary clamping device 110 as the pneumatic clamp 350 moves. Then the pneumatic clamp 350 opens, and the second driving device 340 drives the clamp seat 330 together with the pneumatic clamp 350 to translate along the width direction of the transverse seat 194 away from the transverse driving device 190 and away from the rotary clamping device 110. At this time, the rotary clamping device 110 closes and clamps the end of the wire harness.

[0036] The rotary clamping device 110 includes a first lower clamping mold 111 disposed on a fixed base 122, a first upper clamping mold 112 located above the first lower clamping mold 111 and movably mounted on the fixed base 122, and a first spring 113 abutting between the first upper clamping mold 112 and the fixed base 122. The first spring 113 provides an elastic force to move the first upper clamping mold 112 toward the first lower clamping mold 111. The actuating component 370 is a stop member fixed to the housing of the pneumatic clamp 350. The stop member is provided with a stop inclined surface 371, which gradually slopes upward from one end away from the rear clamping device 200 to the end near the rear clamping device 200. A connecting member 114 is connected to the first upper clamping mold 112. The connecting member 114 is provided with a mating inclined surface 115 whose inclination matches that of the stop inclined surface 371. The first lower clamping mold 111 is provided with a groove for accommodating the power supply wire harness. The sidewall of the groove is formed as a limiting wall for the power supply wire harness to abut against when the pneumatic clamp 350 moves along the width direction of the transverse seat 194. When the first driving device 320 drives the bearing seat 310 together with the clamp seat 330 and the pneumatic clamp 350 to move toward the direction of approaching the rotating clamping device 110, and when the pneumatic clamp 350 moves to abut against the inclined surface 371 and the mating inclined surface 11 of the connector 114, 5. During sliding engagement, the connector 114 moves upward under the abutting action of the abutting inclined surface 371 and the mating inclined surface 115. The first upper clamping mold 112 moves upward with the connector 114 and separates from the first lower clamping mold 111 to open the rotary clamping device 110. At this time, the end of the wire harness exposed outside the pneumatic clamp 350 can extend into the groove of the first lower clamping mold 111 as the pneumatic clamp 350 moves. Then, the clamping base 330 is driven by the second driving device 340 to connect with the connector 114. The pneumatic clamp 350 moves away from the transverse drive device 190 along the width direction of the transverse seat 194. The end of the wire harness remains in the groove under the limiting action of the limiting wall of the groove of the first lower clamping mold 111. When the abutment moves with the pneumatic clamp 350 to separate from the connector 114, the first upper clamping mold 112 moves downward toward the first lower clamping mold 111 under the elastic force of the first spring 113 to cooperate with the first lower clamping mold 111 to clamp the wire harness.

[0037] Specifically, the top of the fixed base 122 is provided with a through hole, and the connecting member 114 includes a push rod connected to the top of the first upper clamping mold 112 and movably passing through the through hole, and a mating plate connected to the top of the push rod. The mating inclined surface 115 is provided on the mating plate. By adopting the above structure, it is convenient to process and manufacture.

[0038] The bearing seat 310 is provided with a guide rod, and both clamp seats 330 are movably mounted on the guide rod, so that the guide rod guides the translation of the clamp seat 330 when it translates.

[0039] The first driving device 320 includes a base 321, a second transmission screw 322 rotatably mounted on the base 321, a second drive motor 323 for driving the second transmission screw 322 to rotate, and a third screw nut 324 matchedly sleeved on the second transmission screw 322. The base 321 extends along the length direction of the transverse seat 194. The bearing seat 310 is movably mounted on the base 321, and the third screw nut 324 is fixed on the bearing seat 310. In use, the second drive motor 323 operates, driving the second transmission screw 322 to rotate, thereby causing the bearing seat 310 together with the third screw nut 324 to translate along the length direction of the transverse seat 194.

[0040] The base 321 is provided with a first guide rail, and the support 310 is provided with a first slider that slides with the first guide rail, thereby improving the smoothness of movement of the support 310.

[0041] Both the first stranded wire clamping device 140 and the second stranded wire clamping device 150 include a second lower clamping mold 141 fixed on the transverse base 130 and a second upper clamping mold 142 that is vertically mounted on the transverse base 130 and located above the second lower clamping mold 141; the opening and closing mechanism 160 includes a first drive cylinder 161 mounted on the transverse base 130, and a second upper clamping mold 142 for abutting against the second upper clamping mold 142 of the first stranded wire clamping device 140 and the second upper clamping mold 142 of the second stranded wire clamping device 150.

The second upper clamping mold 142 of the first stranded wire clamping device 140 and the second upper clamping mold 142 of the second stranded wire clamping device 150 abut against the transverse sliding seat 130. A second spring 163 is provided at the top to provide an elastic force that causes the second upper clamping mold 142 to move upward. Meanwhile, the first drive cylinder 161 drives the linkage plate 162 to move downward.

The shearing device 171 is movably mounted on the second guide rail 181 and connected to the piston rod of the second drive cylinder 182. When the rotating clamping device 110 clamps the end of the wire harness pulled by the wire harness traction and transfer device 300, and the first twisted wire mating clamping device 140, the second twisted wire mating clamping device 150, and the rear clamping device 200 are all closed to clamp the wire harness, the second drive cylinder 182 can drive the cutting device 171 to move toward the first twisted wire mating clamping device 140, and then the cutting device 171 cuts the wire harness located between the first twisted wire mating clamping device 140 and the second twisted wire mating clamping device 150, thereby realizing the cutting of the wire harness.

[0044] The cutting device 171 can be an electric scissor or a pneumatic scissor, as long as it can cut the wire harness.

In use, the fourth drive motor 192 operates, driving the third transmission screw 191 to rotate, thereby causing the transverse shifting seat 130 together with the fourth screw nut 193 to translate along the length of the transverse base 194.

[0046] The horizontal seat 194 is provided with a second guide rail 181, and the horizontal moving seat 130 is provided with a second slider that slides with the second guide rail 181, thereby improving the smoothness of the movement of the horizontal moving seat 130.

A guide channel for the power wire harness is formed between the upper and lower guide rollers of the guide unit 213. In use, the power wire harness is wound on the turntable 212. When the output power wire harness is pulled, the turntable 212 rotates under the traction force to unwind and output the power wire harness. The output power wire harness is guided through the guide channel of the plurality of guide units 213 and transmitted to the stranding processing line 100. As a further preferred embodiment of the present invention, the turntable 212 may also be provided with multiple positioning components, so that when the wire harness is spirally wound on the turntable 212, the positioning components can be used to position the wire harness, thereby facilitating the orderly winding of the wire harness without loosening. The positioning components may be various existing positioning components such as telescopic positioning pins. The support frame 211 may also be rotatably mounted with several guide wheels 214 for guiding the wire harness.
