[0030] When it is necessary to wind and unwind the cable, the winding assembly 2 is started, the winding assembly 2 winds and unwinds the cable, and the first motor 33 is started at the same time, the first motor 33 rotates to drive the reciprocating screw rod 32 to rotate, the reciprocating screw rod 32 rotates to drive the driving block 35 to move, the driving block 35 moves back and forth along the axis direction of the reciprocating screw rod 32 under the action of the connecting plate 37, the guide block 36 and the limiting shaft 34, thereby driving the connecting plate 37 to move back and forth, and the connecting plate 37 moving back and forth can pull and arrange the cable passing through the limiting hole 38, so that the cable is neatly and orderly wound on the winding assembly 2.

[0031] The first motor 33 is fixedly installed on the corresponding support plate 31.

[0032] A plurality of balls 4 are uniformly embedded on the inner wall of the limiting hole 38.

[0033] In this way, the sliding friction between the cable and the limiting hole 38 is converted into rolling friction, the friction coefficient is greatly reduced, the cable moves more easily in the limiting hole 38, efficient and smooth winding and unwinding is ensured, and the driving block 35 driving the cable to move is prevented from being stuck or having uneven speed; the rolling contact can prevent the cable outer skin from being scratched and worn by hard friction, maintain the integrity and quality of the cable surface, and enable the cable to be more stable and accurate in position during guiding, be accurately conveyed to the winding assembly 2 during winding, and be uniformly wound, thereby improving the winding quality.

[0034] The winding assembly 2 comprises a fixed mounting plate 21 fixedly arranged on the top of the base 1 and a movable mounting plate 22 slidingly arranged on the top of the base 1, and the fixed mounting plate 21 and the movable mounting plate 22 are arranged in opposition.

[0035] A winding roller 23 is arranged between the fixed mounting plate 21 and the movable mounting plate 22, and rectangular blocks 24 are symmetrically fixedly arranged at the two ends of the winding roller 23.

[0036] A rotating shaft 25 is rotationally arranged on each side wall of the fixed mounting plate 21 and the movable mounting plate 22, a rectangular slot 26 is formed in each side wall of the two rotating shafts 25, and the rectangular blocks 24 and the rectangular slots 26 are interference-fitted.

[0037] The second motor 27 is fixedly connected to the fixed mounting plate 21, and a power output end of the second motor 27 is in transmission connection with the corresponding rotating shaft 25.

[0038] The base 1 is symmetrically provided with two elastic limiting assemblies 28 on two sides for extruding and fixing the movable mounting plate 22.

[0039] The elastic limiting assembly 28 comprises two fixed plates 281 which are arranged in parallel and at intervals on one side wall of the base 1, and a sliding shaft 282 is fixedly mounted between the two fixed plates 281.

[0040] An L-shaped connecting plate 283 is slidably sleeved on the sliding shaft 282, and one end of the L-shaped connecting plate 283 is fixedly connected with the movable mounting plate 22.

[0041] A spring 284 is also sleeved on the sliding shaft 282, and two ends of the spring 284 are fixedly connected with the L-shaped connecting plate 283 and the corresponding fixed plate 281 respectively.

[0042] In use, first, the rectangular block 24 at one end of the winding roller 23 is aligned with the rectangular groove 26 on the rotating shaft 25 on one side of the fixed mounting plate 21, and then the winding roller 23 is pushed so that the rectangular block 24 is inserted into the rectangular groove 26, and since it is an interference fit, the rectangular block 24 is tightly embedded in the rectangular groove 26, so that one end of the winding roller 23 is connected and fixed with the rotating shaft 25 on the fixed mounting plate 21.

[0043] Then, the movable mounting plate 22 is pulled to overcome the elastic force of the spring 284, so that the movable mounting plate 22 slides on the base 1 away from the fixed mounting plate 21, at this time, the L-shaped connecting plate 283 slides on the sliding shaft 282 along with the movable mounting plate 22, and the spring 284 is further compressed.

[0044] The rectangular block 24 at the other end of the winding roller 23 is aligned with the rectangular groove 26 on the rotating shaft 25 on one side of the movable mounting plate 22, and the movable mounting plate 22 is loosened, and under the action of the restoring force of the spring 284, the movable mounting plate 22 moves towards the fixed mounting plate 21, so that the rectangular block 24 at the other end of the winding roller 23 is inserted into the rectangular groove 26 on the rotating shaft 25 on one side of the movable mounting plate 22, and the installation of the winding roller 23 is completed.

[0045] Subsequently, the second motor 27 is started, and the second motor 27 transmits power to the rotating shaft 25 in transmission connection therewith, and with the rotation of the rotating shaft 25, since the rectangular blocks 24 at both ends of the winding roller 23 are in interference fit with the rectangular grooves 26 on the rotating shaft 25, the rotating shaft 25 drives the winding roller 23 to rotate synchronously.

[0046] The winding roller 23 is continuously rotated under the driving of the second motor 27, and the cable is gradually wound on the winding roller 23, realizing the winding process of the cable; at the same time, in the winding process, the spring 284 in the elastic limiting assembly 28 continuously applies a force to the movable mounting plate 22 towards the fixed mounting plate 21, ensuring the stable installation of the winding roller 23 between the movable mounting plate 22 and the fixed mounting plate 21, preventing the axial movement or loosening of the winding roller 23 during rotation.

[0047] In this way, first, the winding roller 23 is installed through interference fit of the rectangular block 24 and the rectangular groove 26, and the elastic limiting assembly 28 assists the movement of the movable mounting plate 22, which is simple to operate and does not require complex tools and professional skills, saving installation time and improving production preparation efficiency; when disassembling, the winding roller 23 can be easily removed by pulling the movable mounting plate 22 to overcome the spring force of the spring 284 to make the rectangular block 24 disengage from the groove, facilitating subsequent maintenance, replacement and other operations.

[0048] Secondly, the spring 284 in the elastic limiting assembly 28 applies force to the movable mounting plate 22 to stably fix the winding roller 23 at both ends of the rotating shaft 25, avoiding axial movement during winding due to various factors, ensuring uniform and neat winding of the cable, and improving winding quality; and the interference fit ensures that the rotating shaft 25 and the winding roller 23 are tightly connected and synchronously rotated, ensuring the continuity and stability of winding, improving winding efficiency and product quality.

[0049] Thirdly, it can adapt to different specifications of winding roller 23, and rely on interference fit and movable design of the movable mounting plate 22, so that winding rollers 23 meeting the size requirements can be installed and used, reducing equipment cost; it can also meet different working condition requirements, and the elastic limiting assembly 28 can be flexibly adjusted according to the actual force, suitable for various cable winding situations.

[0050] The base 1 is uniformly fixed and mounted with at least two supporting rods 5, one end of the supporting rod 5 extends to the outside of the base 1 and is fixedly connected with a fixed assembly 6.

[0051] The fixed assembly 6 comprises a U-shaped seat 61 fixedly connected with the supporting rod 5, and two rubber wood screws 62 are threadedly sleeved at the bottom of the U-shaped seat 61.

[0052] The top of the rubber wood screw 62 is fixedly connected with an extrusion plate 63, and the extrusion plate 63 is provided with an elastic non-slip pad.

[0053] In use, first, the positioning frame is carried to the predetermined working position, then the opening of the U-shaped seat 61 is directed to the cable harness production workbench, then the bakelite screw 62 is rotated, since the bakelite screw 62 is in threaded connection with the bottom of the U-shaped seat 61, the bakelite screw 62 will gradually move upward, and the extrusion plate 63 connected to the top of the bakelite screw 62 will also move upward, when the extrusion plate 63 contacts the workbench, the bakelite screw 62 is continuously rotated, the extrusion plate 63 will exert pressure on the workbench under the pushing of the bakelite screw 62, at this time, the elastic non-slip pads on the extrusion plate 63 will be deformed due to extrusion, and the friction between the elastic non-slip pads and the work surface will gradually increase, so that the positioning frame is firmly fixed on the cable harness production workbench.

[0054] When it is necessary to disassemble the positioning frame, the bakelite screw 62 is reversely rotated, the bakelite screw 62 gradually moves downward, the pressure of the extrusion plate 63 on the workbench gradually decreases, the elastic non-slip pads return to the original state, and the friction between the elastic non-slip pads and the work surface also decreases, the bakelite screw 62 is continuously rotated until the extrusion plate 63 is completely separated from the workbench, at this time, the positioning frame can be lifted from the working position and carried to other places.

[0055] In this way, first, the bakelite screw 62 pushes the extrusion plate 63 to make the elastic non-slip pads tightly contact the workbench to generate friction, which effectively prevents displacement of the positioning frame caused by vibration due to motor operation, cable winding tension change and the like, and guarantees smooth winding process and product quality.

[0056] Secondly, the elastic non-slip pads can adapt to uneven surfaces, avoid scratches and indentations caused by fixing of metal parts, prolong the service life of the high-precision workbench and reduce maintenance and replacement costs.

[0057] Thirdly, the bakelite screw 62 is in threaded connection with the U-shaped seat 61, and the operation can be completed by rotation, without the need for complex tools and skills, which is beneficial to frequent movement of the positioning frame to adapt to different production layouts or perform equipment maintenance and cleaning and the like, and reduces time and labor costs.

[0058] Finally, the bakelite screw 62 is not conductive, which can prevent electrical safety accidents.

[0059] The winding roller 23 is fixedly connected with a fixing ring 7 near the outer side wall of each end thereof.

[0060] In this way, it is convenient to knot the end of the wound cable.

[0061] In use, first, the positioning frame is carried to the predetermined working position, then the opening of the U-shaped seat 61 is directed towards the cable harness production workbench, then the bakelite screw 62 is rotated, since the bakelite screw 62 is in threaded connection with the bottom of the U-shaped seat 61, the bakelite screw 62 will gradually move upwards, and the extrusion plate 63 connected to the top of the bakelite screw 62 will also move upwards together, when the extrusion plate 63 contacts the workbench, the bakelite screw 62 is continuously rotated, and the extrusion plate 63 will exert pressure on the workbench under the pushing of the bakelite screw 62, at this time, the elastic non-slip pads on the extrusion plate 63 will be deformed due to being extruded, and the friction between the elastic non-slip pads and the work surface will gradually increase, so that the positioning frame is firmly fixed on the cable harness production workbench.

[0062] Then, the cable is passed through the limiting hole 38, and the end of the cable is knotted on the fixing ring 7, and then a few turns of the cable are wound on the winding roller 23, then the second motor 27 is started, the second motor 27 transmits power to the rotating shaft 25 in transmission connection therewith, and with the rotation of the rotating shaft 25, since the rectangular blocks 24 at both ends of the winding roller 23 are in interference fit with the rectangular grooves 26 on the rotating shaft 25, the rotating shaft 25 will drive the winding roller 23 to rotate synchronously.

[0063] The winding roller 23 continuously rotates under the driving of the second motor 27, and the cable will be gradually wound on the winding roller 23, realizing the winding process of the cable; at the same time, in the winding process, the spring 284 in the elastic limiting assembly 28 continuously exerts a force on the movable mounting plate 22 towards the fixed mounting plate 21, ensuring the stable installation of the winding roller 23 between the movable mounting plate 22 and the fixed mounting plate 21, preventing the axial movement or loosening of the winding roller 23 in the rotating process.

[0064] At the same time, the first motor 33 is started, the first motor 33 rotates to drive the reciprocating screw 32 to rotate, the reciprocating screw 32 rotates to drive the driving block 35 to move, the driving block 35 moves back and forth along the axis direction of the reciprocating screw 32 under the action of the connecting plate 37, the guide block 36 and the limiting shaft 34, thereby driving the connecting plate 37 to move back and forth, the back and forth movement of the connecting plate 37 can pull and arrange the cable passing through the limiting hole 38, so as to facilitate the orderly winding of the cable on the winding assembly 2.

[0065] After winding is completed, the first motor 33 and the second motor 27 are turned off, the movable mounting plate 22 is pulled, the movable mounting plate 22 drives the corresponding rotating shaft 25 to separate from the winding roller 23, then the rectangular block 24 at the other end of the winding roller 23 is pulled out of the corresponding rectangular groove 26, when the rectangular blocks 24 at both ends of the winding roller 23 are completely pulled out of the rectangular grooves 26 of the rotating shaft 25, the winding roller 23 can be removed from between the fixed mounting plate 21 and the movable mounting plate 22, completing the disassembly operation of the winding roller 23.

[0066] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application.
