Description

Technical Field

[0001] This invention belongs to the field of cable manufacturing technology, specifically a stripping machine for producing USB cables. Background Technology

[0002] USB cables are widely used in various electronic devices. Their structure typically includes an outer insulation layer, a metal shielding layer (braided mesh and aluminum foil), an inner insulation layer, and internal signal and power wires. During the production and assembly of USB cables, the cable ends need to be stripped to expose the internal wires for soldering or other operations.

[0003] In the manufacturing process of USB cables, the stripping process is used to remove the outer sheath from the cable end to expose the core. Existing stripping equipment usually drives the component to move axially after cutting the outer sheath to peel off the sheath. During this process, the stripping blade often remains in place or fails to completely detach from the core, which makes it easy to scrape the surface of the exposed core during relative movement. This damages the protective layer and integrity of the core, making it prone to oxidation later and causing poor contact with the terminal block, which seriously affects product performance. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a stripping machine for the production of USB cables. By using this device, the problem of existing stripping equipment easily scraping the surface of the exposed wire core, thereby damaging the protective layer and integrity of the wire core, causing the wire core to oxidize easily in the later stage and resulting in poor contact with the terminal block is solved.

The top and bottom of the inner cavity of the connecting plate are rotatably connected to movable rods via bearings. A clamping plate is fixedly installed on the opposite ends of two adjacent movable rods. Several insert teeth are fixedly installed at equal intervals on the opposite sides of the inner cavities of the two clamping plates. A wire roller is fixedly sleeved on the outer periphery of the two top movable rods near the top. Two binding wheels are provided on the other side of the two upright plates, and the two adjacent binding wheels are arranged front and rear. A vertical rod is fixedly installed at the bottom of each binding wheel. The bottom end of each vertical rod is rotatably connected to the placement seat. A connecting rope is wound around the outer periphery of the two wire rollers. A third electric push rod is fixedly installed on the opposite side of the two upright plates near the other side. The power end of the third electric push rod movably passes through the adjacent upright plates and is fixedly connected to the adjacent connecting rope.

[0007] Furthermore, the length of each of the aforementioned prongs is less than the thickness of the outer sheath of the USB connector.

[0008] Furthermore, the side of several of the insert teeth facing the movable rod is an arc surface, and the center of several of the arc surfaces coincides with the center of rotation of the adjacent movable rod. A spring is installed on one side of the two upright plates and between the adjacent clamping plates.

[0009] Furthermore, several protrusions are fixedly installed at equal intervals on opposite sides of the inner cavities of the two clamping plates, and each of the protrusions is located between two adjacent insert teeth.

[0010] Furthermore, the top of the base is provided with several conveying structures, a cutting structure is provided near one side of the top of the base, a second sliding assembly is provided near one side of the top of the base, and a second fixing structure is provided on one side of the second sliding assembly. The composition and connection method of each structure in the first sliding assembly is the same as that of each structure in the second sliding assembly; the composition and connection method of each structure in the first fixing structure is the same as that of each structure in the second fixing structure; an infrared sensor is provided on the second sliding assembly, and a hook structure is provided at the middle position of the top of the base for collecting the cut USB cable.

[0011] Furthermore, the hook structure includes a support frame fixedly installed on the top of the base near the middle position. A servo motor is installed on the top of the support frame. A swing plate is installed on the end of the power output shaft of the servo motor. A semi-circular opening is provided on the bottom of the swing plate near the front side. A flow guide is fixedly installed on the top of the base near the middle position. A collection groove is provided at the bottom of the flow guide, and the collection groove is fixedly connected to the base.

[0012] Furthermore, a sixth electric push rod is fixedly installed on the top of the swing plate near the front side, a folding plate is fixedly installed on the power end of the sixth electric push rod, and a rubber pad is fixedly installed on the bottom of the folding plate.

[0013] Furthermore, the folding plate is a flexible metal plate.

[0014] Furthermore, the conveying structure includes two L-shaped plates fixedly installed on the top of the base near one side. Each L-shaped plate has several guide wheels at its top, and vertical rods are fixedly installed at the bottom of each guide wheel. The bottom ends of the vertical rods movably penetrate the top of adjacent L-shaped plates. Synchronous pulleys are fixedly fitted around the outer periphery of several vertical rods on the front side and several vertical rods on the rear side near their bottom ends. The synchronous pulleys on the front side are connected to each other via adjacent synchronous belts. Rotary gears are fixedly fitted around the outer periphery of the two vertical rods on one side near their bottom ends, and these rotating gears mesh with each other. A support plate is fixedly installed at the bottom of the front L-shaped plate, and a drive motor is installed at the bottom of the support plate. The power shaft of the drive motor is fixedly connected to the adjacent vertical rod.

[0015] The beneficial effects of this invention are as follows: 1. This invention first uses a stripper to cut the outer sheath of the USB connector cable, then the stripper retracts outward to detach from the wire core, and then the sheath is clamped by a clamping structure and pulled out of the wire core by the first sliding component. This achieves separation of the cutting and pulling actions, effectively avoiding the stripper scraping the surface of the wire core during axial displacement, preventing damage and peeling of the protective layer on the surface of the wire core, and thus avoiding the problem of poor contact caused by oxidation of the terminal block due to damage to the wire core, thereby improving the stripping quality.

[0016] 2. This invention, through the cooperation of a third electric push rod, connecting rope, and binding wheel, converts linear traction force into rotational torque on the wire roller, causing the insert teeth to equidistantly penetrate the outer sheath, resulting in uniform force distribution, stable gripping, and prevention of slippage or detachment. The length of the insert teeth is less than the thickness of the sheath to prevent damage to the wire core. During resetting, it is pulled by a spring, and the center of the arc surface of the insert teeth coincides with the rotation center of the movable rod, so that the movement direction of the tooth tip is tangent to the arc surface, avoiding reverse hooking and achieving smooth material unloading.

[0017] 3. This invention provides a protrusion between two inserts. When the inserts penetrate the outer skin, the protrusion is compressed and undergoes elastic deformation. When the inserts separate, the protrusion rebounds outwards due to its own elastic restoring force, applying a reverse pushing force to the peeled-off sheath. This effectively prevents the cut sheath from getting stuck on the outside of the inserts, ensuring the continuity and smoothness of the peeling operation.

[0018] 4. In this invention, the hook structure is driven by a servo motor to rotate the swing plate, and uses the semi-circular opening to move one end of the connecting wire toward the middle, achieving accurate positioning and working space for single-end processing; at the same time, the sixth electric push rod lifts the elastic metal folding plate, causing it to bend and deform along the semi-circular opening, and with the rubber pad, it flexibly wraps and clamps the wire, ensuring a stable clamping without damaging the wire. After being released, the wire automatically falls into the collection trough, realizing automated collection after processing, reducing manual intervention and improving production efficiency.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 - Figure 12 As shown, a stripping machine for producing USB cables includes a base 1, a first sliding assembly, and a first fixing structure (the first fixing structure includes a second connecting seat 41 fixed to the top of the base 1, the second connecting seat 41 having a first through-hole, and an arc-shaped opening at the bottom of the inner cavity of the first through-hole; a fifth electric push rod 43 is mounted on the top of the second connecting seat 41, the power end of the fifth electric push rod 43 movably passes through the inner cavity of the first through-hole, and is fixedly connected to a pressing block 42); the first fixing structure is used to limit the movement of the USB cable; slide rails 2 are installed on the top of the base 1 near both the front and rear sides; the first sliding assembly includes a placement seat 3 located on the top of the base 1 near the other side (the top of the placement seat 3 has a placement groove, and the... The inner walls of the placement slot are all inclined to facilitate the cable falling in. A slider 20 is fixedly installed at the bottom of the placement seat 3, and the slider 20 is slidably connected to the adjacent slide rail 2. A fixing plate 4 is fixedly installed on the top of the base 1 near the other side. A first electric push rod 5 is installed on the other side of the fixing plate 4. The power end of the first electric push rod 5 is fixedly connected to the placement seat 3. Upright plates 8 are fixedly installed on the top of the placement seat 3 near the front and rear sides. A second electric push rod 6 is installed on the opposite side of the two upright plates 8. A stripping knife 7 is installed on the power end of the second electric push rod 6 for cutting the outer sheath of the USB cable. A clamping structure is provided on the opposite side of the two upright plates 8 for clamping the cut USB cable sheath.

[0024] First, the USB cable is secured by the first fixing structure. Then, the second electric push rod 6 drives the two adjacent stripping blades 7 to move relative to each other, cutting off the outer sheath of the USB cable. After cutting, the second electric push rod 6 moves again, causing the stripping blades 7 to retract outward and detach from the USB cable. Next, the clamping structure is activated and clamps and fixes the cut outer sheath. After the clamping and fixing work is completed, the first electric push rod 5 is activated, driving the placement seat 3 to slide axially along the slide rail 2 under the guidance of the slider 20, detaching the cut sheath from the USB cable core. This effectively prevents the stripping blades 7 from scraping the surface of the core during axial displacement, avoiding damage and peeling of the protective layer on the core surface, protecting the integrity of the core, and preventing the terminals from easily oxidizing and causing poor contact due to damage to the core later.

[0025] like Figure 3 , Figure 5 and Figure 6 As shown, the clamping structure includes a connecting plate 9 fixedly installed on one side of the upright plate 8 near the middle position. The top and bottom of the inner cavity of the connecting plate 9 are rotatably connected to movable rods 10 via bearings. Clamping plates 11 are fixedly installed on opposite ends of two adjacent movable rods 10. Several insert teeth 12 are equidistantly fixedly installed on opposite sides of the inner cavities of the two clamping plates 11. Wire rollers 17 are fixedly sleeved on the outer periphery of the two top movable rods 10 near their top ends. Two binding wheels 15 are provided on the other side of the two upright plates 8, with adjacent binding wheels 15 arranged front and rear. Upright rods 16 are fixedly installed at the bottom of each binding wheel 15. The bottom ends of the upright rods 16 are... Rotatably connected to the placement base 3, both rollers 17 are wound with connecting ropes 18 around their outer circumference (one end of the connecting rope 18 is fixed and wound around the outer circumference of the roller 17, and the other end of the connecting rope 18 extends outward and passes around two adjacent front and rear restraint wheels 15, using the wheel groove or outer circumference of the restraint wheel 15 to guide and restrain the connecting rope 18, and then the end of the connecting rope 18 passes through the adjacent upright plate 8 and is fixedly connected to the power end of the third electric push rod 14). The third electric push rod 14 is fixedly installed on the opposite side of the two upright plates 8 near the other side, and the power end of the third electric push rod 14 moves through the adjacent upright plate 8 and is fixedly connected to the adjacent connecting rope 18.

[0026] When stripping the USB cable, the third electric push rod 14 is activated and pulls back the connecting rope 18. Under the guidance and constraint of the two adjacent binding wheels 15, the linear traction force of the connecting rope 18 is converted into the rotational torque of the wire roller 17, causing it to rotate. The rotation of the wire roller 17 synchronously drives the movable rod 10 to rotate, which in turn drives the clamping plate 11 fixed at the end of the movable rod 10 to swing. As the two clamping plates 11 rotate towards each other and close, the inserts 12 provided on their inner sides pierce and bite into the outer sheath of the USB cable. The equidistant distribution of the inserts 12 makes the clamping force more uniform, which can achieve stable gripping and fixing of the cable sheath, avoiding relative slippage or detachment of the USB cable during the subsequent stripping and pulling process, and improving the success rate of removing the USB cable sheath.

[0027] like Figure 11 As shown, the length of each of the several prongs 12 is less than the thickness of the outer sheath of the USB cable.

[0028] Because the insert 12 is short, only the insert 12 penetrates the outer sheath without scratching the internal wire core.

[0029] like Figure 5 , Figure 6 and Figure 11 As shown, the sides of several insert teeth 12 facing the movable rod 10 are all arc surfaces, and the centers of several arc surfaces coincide with the rotation centers of the adjacent movable rods 10. A spring 19 is installed on one side of the two upright plates 8 and between the adjacent clamping plates 11.

[0030] When the two clamping plates 11 are reset, the clamping plates 11 deflect in the opposite direction around the adjacent movable rod 10 due to the pulling force of the spring 19. Since the center of the arc surface on the insert tooth 12 coincides with the rotation center of the movable rod 10, the movement trajectory of the clamping plate 11 during deflection is completely consistent with the curvature of the arc surface. Therefore, during the process of the insert tooth 12 detaching from the outer sheath of the USB connector cable, the movement direction of the tooth tip is tangent to the arc surface, and it will not have a reverse hooking effect on the sheath. This avoids the insert tooth 12 hooking the peeled sheath during the peeling process, and achieves smooth material removal without interference.

[0031] like Figure 11 As shown, several protrusions 13 are fixedly installed at equal intervals on opposite sides of the inner cavity of the two clamping plates 11, and each protrusion 13 is located between two adjacent insert teeth 12 (the protrusions 13 are made of elastic rubber or silicone).

[0032] When the prongs 12 pierce the outer sheath of the USB cable, the protrusions 13 come into contact with the cable and are compressed, resulting in elastic deformation. When the prongs 12 move outward and separate from the outer sheath of the cable, the protrusions 13 rebound outward with their own elastic restoring force, applying a reverse pushing force to the stripped sheath. This prevents the cut sheath from getting stuck on the outside of the prongs 12 when they are withdrawn, ensuring the smooth progress of the stripping operation.

[0033] like Figure 1 , Figure 2 and Figure 9 As shown, the top of the base 1 is provided with several conveying structures. Near one side of the top of the base 1, a cutting structure is provided (the cutting structure includes a first connecting seat 38 fixedly installed on the top of the base 1, a second through-hole on the first connecting seat 38, and a fourth electric push rod 39 installed on the top of the first connecting seat 38; a cutting blade 40 is fixedly installed on the power end of the fourth electric push rod 39 for cutting the USB cable). Near one side of the top of the base 1, a second sliding assembly is provided. A second fixing structure is provided on one side of the second sliding assembly. The composition and connection method of each structure in the first sliding assembly are the same as those in the second sliding assembly; the composition and connection method of each structure in the first fixing structure are the same as those in the second fixing structure; an infrared sensor 21 is provided on the second sliding assembly; and a hook structure is provided at the middle of the top of the base 1 for collecting the cut USB cable.

[0034] When processing both ends of the USB connector, the cutting blade 40 is first driven by the fourth electric push rod 39 to cut the USB connector. After the right end of the USB connector is pressed by the first fixing structure, the hook structure hooks the middle position of the cut USB connector, thereby moving the unfixed left end towards the middle position. After the infrared sensor 21 detects the left end of the USB connector and it reaches the preset position, the second fixing structure fixes the USB connector, and the hook structure stops working. Then, the two stripping blades 7 on the second sliding assembly move relative to each other to cut the outer insulation layer of the USB connector. Finally, the clamping structure clamps the cut outer layer, and the first electric push rod 5 on the second sliding assembly peels the outer layer off the left end of the USB connector. In this way, the outer insulation layers of both ends of the USB connector are removed simultaneously with the first sliding assembly and the first fixing structure, thereby improving production efficiency.

[0035] like Figure 10As shown, the hook structure includes a support frame 22 fixedly installed on the top of the base 1 near the middle position. A servo motor 23 is installed on the top of the support frame 22. A swing plate 24 is installed on the end of the power output shaft of the servo motor 23. A semi-circular opening is provided at the bottom of the swing plate 24 near the front side. A flow guide 25 is fixedly installed on the top of the base 1 near the middle position. A collection groove 26 is provided at the bottom of the flow guide 25, and the collection groove 26 is fixedly connected to the base 1.

[0036] Driven by the rotation of the power output shaft of the servo motor 23, the swing plate 24 fixed to its shaft end rotates accordingly. As the swing plate 24 swings, the semi-circular opening at its bottom abuts against the USB cable and applies a lateral thrust to the middle section of the cable, forcing the left end of the USB cable to move towards the middle and bend. This causes the left end of the USB cable to automatically move to the preset position of the second fixed structure, thus providing accurate positioning and working space for the processing of the single end of the USB cable. After processing is completed, the first and second fixed structures release the restriction on both ends of the USB cable, and the swing plate 24 continues to swing, thereby pulling the USB cable that has been cut away from its original position and allowing it to fall into the collection trough 26, thus collecting the finished product.

[0037] like Figure 10 As shown, a sixth electric push rod 27 is fixedly installed on the top of the swing plate 24 near the front side, a folding plate 28 is fixedly installed on the power end of the sixth electric push rod 27, and a rubber pad 29 is fixedly installed on the bottom of the folding plate 28.

[0038] When the rubber pad 29 initially contacts the USB cable, the sixth electric push rod 27 is activated, driving the folding plate 28 to move towards the inner wall of the semi-circular opening. Due to the limiting and squeezing effect of the edge structure of the semi-circular opening, the folding plate 28 undergoes adaptive bending deformation along the inner wall of the semi-circular opening, which in turn causes the rubber pad 29 on its surface to deform synchronously, tightly wrapping and flexibly clamping the USB cable from all sides. When it is necessary to discharge the processed USB cable into the collection groove 26, the sixth electric push rod 27 moves away from the inner wall of the semi-circular opening to reset, the folding plate 28 loses its pushing force and springs back, thereby releasing the clamping and fixing of the USB cable, allowing the cable to fall smoothly into the collection groove 26 under the action of gravity.

[0039] Folding plate 28 is a flexible metal plate.

[0040] By utilizing the excellent deformation and rebound capabilities of elastic metal, the folding plate 28 can smoothly bend along the semi-circular opening when lifted by the sixth electric push rod 27, and quickly return to its original shape by its own elasticity when reset. In addition, the elastic metal has extremely high fatigue strength and is not prone to plastic deformation or breakage in long-term frequent bending and reciprocating operations, thus extending the service life of the elastic metal plate.

[0041] like Figure 1 , Figure 2 and Figure 7 As shown, the conveying structure includes two L-shaped plates 30 fixedly installed on the top of the base 1 near one side. Each L-shaped plate 30 has several guide wheels 31 on its top. Each guide wheel 31 has a vertical rod 32 fixedly installed at its bottom. The bottom ends of the vertical rods 32 movably pass through the top of the adjacent L-shaped plates 30. Synchronous wheels 33 are fixedly sleeved on the outer periphery of the several vertical rods 32 on the front side and the several vertical rods 32 on the rear side near their bottom ends. The several synchronous wheels 33 on the front side are connected to each other by adjacent synchronous belts 34. Rotary gears 35 are fixedly sleeved on the outer periphery of the two vertical rods 32 on one side near their bottom ends. The rotating gears 35 are meshed with each other. A support plate 36 is fixedly installed on the bottom of the L-shaped plate 30 on the front side. A drive motor 37 is installed on the bottom of the support plate 36. The power shaft of the drive motor 37 is fixedly connected to the adjacent vertical rod 32.

[0042] When the drive motor 37 starts, it drives the connected vertical rod 32 to rotate. Through the meshing rotating gear 35, it synchronously drives the vertical rod 32 on the other side to rotate. Then, through the transmission action of the synchronous pulley 33 and the synchronous belt 34, all the vertical rods 32 on the same side rotate synchronously in the same direction, thereby driving all the guide pulleys 31 to rotate synchronously. This can transport the USB cable to be processed to the device at a uniform speed, ensuring a stable and uniform feeding process. Because the USB cable integrates multiple copper wire cores, a metal braided shielding mesh, and an aluminum foil shielding layer, as well as an insulation layer and an outer sheath, it can transport the USB cable to be processed to the device at a uniform speed, ensuring a stable and uniform feeding process. It also has a certain thickness and hardness, which makes the entire wire exhibit high rigidity and hardness, making it less prone to natural bending. This avoids the wire warping, swaying or arching due to its own rigidity when entering the next conveying structure in the absence of lateral constraint and guidance from the guide wheel 31, which would prevent the end from being aligned and smoothly passing through the gap between the next set of guide wheels 31, thus causing feeding interruption. Moreover, arc-shaped guide grooves are set on both sides of the USB wire in the gap where there is no drive and guidance from the guide wheel 31, further ensuring that the USB wire can be automatically conveyed forward under the conveying and traction of the guide wheel 31.

[0043] During operation, firstly, the drive motor 37 in the conveying structure is started. The drive motor 37 drives the vertical rod 32 connected to it to rotate. Through the meshing rotating gear 35, it synchronously drives the vertical rod 32 on the other side to rotate. Then, through the transmission action of the synchronous pulley 33 and the synchronous belt 34, all the vertical rods 32 on the same side rotate synchronously in the same direction, thereby driving all the guide pulleys 31 to rotate synchronously, conveying the USB cable to be processed into the inner side of the device at a uniform speed and stably. The second electric push rod 6 located on the vertical plate 8 is started, driving the two stripping blades 7 to move relative to each other, piercing into the outer sheath of the USB cable and cutting it in a ring. After the cutting is completed, the stripping blades 7 immediately retract and detach from the cable body to avoid scratching the core of the cable during subsequent axial movement. After the cutting is completed, the clamping structure is started, and the third electric push rod 14 pulls back the connecting rope 18. Under the guidance of the restraint wheel 15, the tension of the connecting rope 18 is converted into the rotational torque of the wire roller 17, driving the movable rod 10 to rotate, thereby driving the two clamping plates 11 to swing and close towards each other. The insert teeth 12 on the inner side of the clamping plate 11 rotate smoothly. The inserter 12 pierces the outer sheath. Because the length of the insert 12 is less than the thickness of the sheath, it only pierces the surface without damaging the internal core. Simultaneously, the protrusion 13 is compressed and undergoes elastic deformation, preparing for subsequent material removal. After the clamp is securely fixed, the first electric push rod 5 is activated, driving the placement seat 3 to slide axially under the guidance of the slider 20 and the slide rail 2. Since the clamp structure has already engaged and fixed the cut sheath, the movement of the placement seat 3 causes the sheath to shift axially, thereby peeling and pulling the cut insulating sheath off the core. The process uses a purely mechanical pulling method to remove the outer sheath, effectively avoiding axial scraping of the wire core surface by the cutter and protecting the integrity of the wire core. After stripping, the third electric push rod 14 is reset, the connecting rope 18 is loosened, and under the tension of the spring 19, the clamping plate 11 is deflected in the opposite direction and reset. Since the center of the arc surface of the insert tooth 12 coincides with the rotation center of the movable rod 10, the insert tooth 12 will not hook the sheath when it is withdrawn. At the same time, the protrusion 13 rebounds by relying on the elastic restoring force, pushing out the sheath stuck between the insert teeth 12, thus achieving automatic unloading.When processing one end of the USB connector, the fourth electric push rod 39 is activated first, driving the cutting blade 40 downward to cut the USB connector. Then, the servo motor 23 in the hook-and-loop structure drives the swing plate 24 to rotate. The semi-circular opening at the bottom of the swing plate 24 contacts the USB connector, applying a lateral thrust that forces one end of the connector to bend towards the center. At this time, the sixth electric push rod 27 drives the folding plate 28 and rubber pad 29 to rise. The folding plate 28 deforms under pressure, and the rubber pad 29 flexibly clamps the connector, providing positioning space for single-end processing. As the swing plate 24 moves, the infrared sensor 21 detects the position of the end point of the USB connector. Subsequently... The second fixing structure is activated, and the fifth electric push rod 43 drives the pressing block 42 downward, which, in conjunction with the arc-shaped opening on the second connecting seat 41, presses and fixes the USB cable. After fixing, the action of removing the leather sleeve is as described above and will not be repeated here. After the work is completed, the first and second fixing structures release the restriction on both ends of the USB cable, the sixth electric push rod 27 in the hook structure moves downward to reset, the folding plate 28 springs back to release the clamp on the USB cable, and the servo motor 23 drives the swing plate 24 to rotate again, pulling the processed USB cable away from the workstation so that it falls into the collection groove 26 under gravity, completing the entire processing cycle.

[0044] The embodiments of the present invention have been described above with reference to the accompanying drawings.
