Description

Technical Field

[0001] This invention relates to the field of cable laying equipment technology, and more specifically to a multifunctional cable laying equipment based on cable processing. Background Technology

[0002] In the field of coaxial cable manufacturing, the insulation processing of the inner conductor is a critical step. The top-drawing technique is commonly used to pull the coiled inner conductor upwards. While this process is widely used, it has inherent drawbacks: when the inner conductor is released from the fixed material frame, circumferential twisting creates microscopic ripples that are difficult to eliminate. These latent stress ripples within the conductor can induce low-frequency standing waves during signal transmission, leading to signal integrity degradation and severely impacting high-frequency communication quality.

[0003] While current mainstream equipment can perform basic cable laying functions, it has obvious shortcomings in practical applications: the rigid equipment structure makes it difficult to adapt to different specifications of reels, and operators need to frequently adjust mechanical parts; there are safety hazards in the process of replacing heavy reels; more importantly, conventional straightening devices cannot eliminate residual torsional stress inside the conductor, causing invisible distortion in the insulation foam layer, which ultimately leads to periodic fluctuations in cable transmission performance.

[0004] To address the issue of residual stress, existing technology has proposed a patent, CN115295251B. This solution provides a coaxial cable inner conductor top-drawing un-twisting and unwinding device, comprising: a rotating platform for placing a disc-shaped inner conductor; a drive mechanism connected to the rotating platform and capable of driving the rotating platform to rotate; and an top-drawing guide wheel frame, on which multiple guide wheels are arranged, including a first guide wheel positioned above the rotating platform. The first guide wheel is positioned substantially along the tangent direction of the disc-shaped inner conductor, and the inner conductor is vertically drawn upwards and passes around the first guide wheel. This device drives the disc-shaped inner conductor to rotate through the rotating platform and vertically draws the inner conductor out from above. The inner conductor only moves in a straight line without rotation around its own axis. Therefore, the coaxial cable produced will not exhibit fluctuations caused by torsion, and there will be no periodic ripples caused by torsion. After foaming, these ripples will not appear on the insulation foam layer, and the low-frequency standing wave index of the cable is significantly improved.

[0005] However, this technology still has the following shortcomings: when the reel is exhausted and a new one needs to be replaced, the production line must be completely stopped. First, the several-ton empty reel must be disassembled, then the new reel must be hoisted, and finally the conductor joints must be manually welded. The lengthy reel-changing process not only causes a significant drop in production efficiency, but also, since cable production is an assembly line operation, excessive time wasted during reel-changing will inevitably cause delays in upstream and downstream processing. In particular, the hot melt material in the sheath extruder forms a weak joint due to stagnant cooling. If this step takes too long, it can easily cause imbalance in the traction system, resulting in uneven insulation layer thickness, thus affecting the processing quality of the cable. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional cable laying device based on cable processing, so as to eliminate residual torsional stress inside the conductor and solve the problem of long waiting time for changing reels.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A multifunctional cable feeding device based on cable processing includes a rotating frame, a drive component, and a guide wheel frame. Rotatable guide wheels are installed on the top and inner side of the guide wheel frame. It also includes: a cable storage component installed on the upper part of the guide wheel frame for storing the end cable when the cable reel is fully released; a locking component installed on the lower part of the guide wheel frame for securing the cable end; and a feeding component for quick reel replacement. Two sliding blocks are fixedly connected to the top of the guide wheel frame. Movable rods are slidably connected between the inner walls of the sliding blocks. Guide wheels are rotatably connected to the bottom of each movable rod, and limit plates are fixedly connected to the top of each movable rod. The two movable rods have different lengths. A mounting plate is fixedly connected to the top of the guide wheel frame. A sprocket is rotatably connected to one side of the mounting plate. A chain is fixedly connected between the tops of the two limit plates, the chain looping around the sprocket, and a transmission connection is established between the chain and the sprocket.

[0009] By adopting the above technical solution, a cable storage component is set up to store part of the cable when the cable reel is released to near the end; and a locking component is set up to fix the end of the cable, so that the end of the cable remains stationary during subsequent processing. At this time, the reel can be replaced and the old and new cables can be welded. At the same time, the cable storage component releases the cable for cable processing, so there is no need to stop the machine and the processing efficiency is improved.

[0010] A further improvement of the technical solution of the present invention is as follows: the feeding component includes a base, a core column is fixedly connected to the center of the top of the base, a hollow column is sleeved on the outside of the core column, the hollow column is rotatably connected to the base, the side wall of the hollow column is symmetrically provided with strip grooves, the top view of the strip grooves is cross-shaped, the inside of each strip groove is slidably connected with a transmission column, the transmission column has a rectangular part that fits into the strip groove, the side wall of the core column is provided with a reciprocating spiral groove, one end of the transmission column is slidably connected to the reciprocating spiral groove, the top of the reciprocating spiral groove is tilted to one side, the ends of the two transmission columns away from the reciprocating spiral grooves are fixedly connected with a support plate, two rotating frames are provided, and they are respectively rotatably connected to the top of the two support plates, a positioning component is provided on the top of the hollow column, the positioning component is used to fix the hollow column, and a top plate is fixedly connected to the top of the hollow column.

[0011] By adopting the above technical solution, by setting up a feeding component with two stations, the loading of the wire rolls on the other station can begin while the wire is being fed normally at one station. When a change is needed, the station can be switched directly to complete the loading. At this time, only welding is required.

[0012] A further improvement of the technical solution of the present invention is that: the positioning component includes two cylinders symmetrically and fixedly connected to the top of the top plate; two connecting rods are symmetrically and slidably connected to the top of the top plate; a second piston plate is fixedly connected to the top of the connecting rod; the second piston plate is tightly fitted to the inner wall of the cylinder; the bottom of the connecting rod extends to the bottom of the top plate and is fixedly connected to the support plate; the two cylinders are connected by a retarder tube, and an electric valve is provided in the middle of the retarder tube; the area of ​​the cylinder above the second piston plate and the inside of the retarder tube are filled with hydraulic oil.

[0013] By adopting the above technical solution, the positioning component can lock the hollow rod while limiting the speed of the support plate's movement and the speed of the hollow column's rotation, thereby reducing the impact generated during workstation switching.

[0014] A further improvement of the technical solution of the present invention is as follows: the driving component includes a driving motor, which is fixedly mounted on the base plate of the guide wheel frame. The bottom of the central shaft of the rotating frame extends to the bottom of the support plate and has a spline groove. A support frame is fixedly connected to the base plate of the guide wheel frame. Several sliding rods are fixedly connected between the support frame and the base plate of the guide wheel frame. A support plate is slidably connected between the sliding rods. A third spring is sleeved on the outside of the sliding rods below the support plate. A driven gear is rotatably connected to the top of the support frame. A driving gear is fixedly connected to the output end of the driving motor. The driving gear meshes with the driven gear. The central shaft of the driven gear is set as a hollow structure, and a spline shaft is slidably connected inside. The top of the spline shaft is inserted into the spline groove. The bottom of the spline shaft extends to the bottom of the support frame and is fixedly connected to the support plate. An iron block is fixedly connected to the bottom of the support plate. An electromagnet is fixedly connected to the base plate of the guide wheel frame.

[0015] By adopting the above technical solution, a drive component that can be freely detached from and docked with the rotating frame is set up. When it is necessary to lay the wire, the power transmission can be carried out by docking the drive component with the rotating frame. When switching workstations, the drive component can be detached from the rotating frame. In this way, a single drive can meet the rotation requirements of the rotating frame at two workstations.

[0016] A further improvement of the technical solution of the present invention is that: the wire storage component includes a take-up device fixedly installed on the top of the guide wheel frame, a guide rod is fixedly connected inside the guide wheel frame, a traction frame is sleeved on the outside of the guide rod, the movable part of the take-up device is fixedly connected to the traction frame, and a traction wheel is rotatably connected to the inner side of the traction frame.

[0017] By adopting the above technical solution, the cable storage component can not only store cables for temporary use, but also quickly retract the cable end area to avoid being pressed or tangled.

[0018] A further improvement of the technical solution of the present invention is as follows: the locking component includes a fixing plate, which is fixedly installed on one side of the guide wheel frame. A through hole is provided on the fixing plate, and a rod is slidably connected inside the through hole. A hook is fixedly connected to one end of the rod, and the end of the rod away from the hook extends to the other side of the fixing plate and is fixedly connected to a pad. A first spring is sleeved on the outside of the rod and between the pad and the fixing plate. A ball bearing is fixedly connected inside the through hole, and a transmission groove is provided on the outside of the rod. The transmission groove slides with the ball bearing. The part of the transmission groove near the hook is spiral-shaped, and the spiral part is wound around the outer wall of the rod to form a spiral transmission structure together with the ball bearing. The part of the transmission groove away from the hook is a straight groove. A buckle structure is provided on the side of the fixing plate near the hook, and a positioning block is fixedly connected to the end of the rod near the hook. A slot is provided on the outside of the positioning block, and the rod is locked by the buckle structure cooperating with the slot.

[0019] Using the above technical solution, during normal cable feeding, the cable between the reel and the guide wheels on the side wall of the guide wheel frame is straightened by traction. The cable forms a bend at the hook position, causing the hook to move away from the pad, which in turn moves the pad and compresses the first spring. At the end of the feeding, the cable end is no longer restrained and therefore cannot maintain the bend, allowing the potential energy of the first spring to be released, pushing the pad back to its original position and causing the hook to move. In the initial stage of the hook's movement, the sliding ball is in the straight groove of the transmission groove, so the hook moves linearly along with the insertion rod. When the sliding ball slides to the spiral part of the transmission groove, the continued movement of the insertion rod causes the hook to rotate, thereby winding up the cable end until the buckle structure and the slot cooperate to fix the positioning block. At this point, the cable end cannot be pulled.

[0020] A further improvement of the technical solution of the present invention is that: an air cylinder is fixedly connected to the column on one side of the guide wheel frame, and a first piston plate is fixedly connected to the end of the pad block away from the insertion rod. The first piston plate is tightly fitted with the inside of the air cylinder, and a flow-limiting hole communicating with the outside is opened on the air cylinder.

[0021] By adopting the above technical solution, the movement speed of the pad is limited by air pressure, thereby slowing down the movement speed of the insertion rod and hook, so as to provide the cable storage component with sufficient cable storage time;

[0022] A further improvement of the technical solution of the present invention is that: the buckle structure includes a buckle seat, which is fixedly connected to the side wall of the fixing plate. The buckle seat has a through groove with a matching shape of the positioning block. A slider is slidably connected between the inner walls of the buckle seat. A fourth spring is fixedly connected between the top of the slider and the top of the inner wall of the buckle seat. A wedge is fixedly connected to the bottom plate of the slider. The side of the wedge away from the slider has an inclined surface and extends into the inside of the through groove. The wedge is slidably connected to the buckle seat. A toggle groove is provided on one side of the buckle seat. A lever is fixedly connected to the slider. The lever extends to the outside of the buckle seat through the toggle groove. The buckle groove is set as an annular groove.

[0023] Using the above technical solution, after replacing and welding the reel, by pushing the lever upward, the slider moves upward, squeezing the fourth spring and causing the wedge to leave the slot, and unwinding can begin. During the unwinding process, the cable at the end hook is straightened, which moves the hook, thereby moving the insert rod and the pad, squeezing the first spring. At this time, the slot and the wedge are misaligned, and the lever can be released.

[0024] A further improvement to the technical solution of the present invention is that a rubber pad is fixedly connected to the outer side wall of the hook.

[0025] Using the above technical solution, during normal cable laying, the cable does not contact the outside of the hook, so the rubber pad will not affect normal cable laying. When the cable is wound around by the hook's rotation, the cable is wound and tightly attached to the rubber pad, which makes the cable and the hook have greater friction, making it less likely to be pulled and improving the stability of the cable end locking.

[0026] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0027] 1. This invention provides a multi-functional cable feeding device based on cable processing. By setting up a cable storage component, a portion of the cable is stored by the cable storage component when the cable reel is released to near the end; and a locking component is set up to fix the end of the cable, so that the end of the cable remains stationary during subsequent processing. At this time, the cable reel can be replaced and the old and new cables can be welded. At the same time, the cable is released by the cable storage component for cable processing. Therefore, there is no need to stop the machine, which improves the processing efficiency.

[0028] 2. This invention provides a multi-functional wire feeding device based on cable processing. By setting up a feeding component with two stations, the wire reel on the other station can be loaded while the wire is being fed normally at one station. When a replacement is needed, the station can be switched directly to complete the loading of the reel. At this time, only welding is required, thereby improving the efficiency of wire reel replacement and reducing the impact of wire reel replacement on upstream and downstream processing.

[0029] 3. This invention provides a multi-functional cable laying device based on cable processing. By setting a drive component that can be freely detached from and docked with the rotating frame, power transmission can be achieved by docking the drive component with the rotating frame when cable laying is required. When switching workstations, the drive component can be detached from the rotating frame. In this way, a single drive can meet the rotation requirements of the rotating frame at two workstations, saving implementation costs.

[0030] 4. This invention provides a multi-functional wire feeding device based on cable processing. By setting up a wire storage component, during normal unwinding, the traction wheel is pulled by the traction action at the production end, causing the traction frame to slide downward and pulling out the movable part on the take-up device, where the internal coil spring accumulates potential energy. When the cable on the coil is completely released or the remaining cable is insufficient to connect the cable to the coil, the potential energy of the coil spring begins to be released, thereby pulling the traction frame upward and driving the end cable to move quickly. Because the production end is not moved due to the traction action, but the end of the cable is detached from the coil, it will be quickly pulled away, thus realizing wire storage on the one hand and avoiding being pressed or tangled by the feeding component on the other.

[0031] 5. This invention provides a multifunctional cable feeding device based on cable processing. By setting a locking component, during normal cable feeding, the cable between the spool and the guide wheel set on the side wall of the guide wheel frame is straightened by traction. The cable forms a corner at the hook position, causing the hook to move away from the pad, which in turn moves the pad and squeezes the first spring. When the cable feeding ends, the end of the cable is unrestrained and therefore cannot maintain the corner, so the potential energy of the first spring is released, pushing the pad to reset and moving the hook. Through the action of the ball bearing and the transmission groove, the hook rotates, winding up the end of the cable, thereby ensuring that the end of the cable is fixed and facilitating welding.

[0044] The present invention will be further described in detail below with reference to the embodiments.

[0045] Example 1

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, this invention provides a multifunctional cable feeding device based on cable processing, including a rotating frame 304, a driving component, and a guide wheel frame 1. Rotatable guide wheels are installed on the top and inner side of the guide wheel frame 1. It also includes: a cable storage component, installed on the upper part of the guide wheel frame 1, for storing the end cable when the cable reel is fully released; a locking component, installed on the lower part of the guide wheel frame 1, for fixing the cable end; and a feeding component for quickly changing the cable reel. Two slide blocks 201 are fixedly connected to the top of the guide wheel frame 1. Movable rods 202 are slidably connected between the inner walls of each of the two rods 202. Guide wheels 206 are rotatably connected to the bottom of each of the two rods 202. Limiting plates are fixedly connected to the top of each of the two rods 202. The two rods 202 have different lengths. Mounting plate 203 is fixedly connected to the top of the guide wheel frame 1. A sprocket 204 is rotatably connected to one side of the mounting plate 203. A chain 205 is fixedly connected between the tops of the two limiting plates. The chain 205 passes around the sprocket 204, and the chain 205 and the sprocket 204 are connected by a transmission.

[0047] In this embodiment, by setting up a cable storage component, a portion of the cable is stored when the cable reel is released to near the end; and a locking component is set up to fix the end of the cable, so that the end of the cable remains stationary during subsequent processing. At this time, the reel can be replaced and the old and new cables can be welded. At the same time, the cable storage component releases the cable for cable processing, so there is no need to stop the machine, which improves the processing efficiency.

[0048] Based on the above structure, by making the guide wheel 206 for stress relief a movable structure, during normal cable laying, because the two movable rods 202 have different lengths, the longer movable rod 202 has a greater mass than the shorter movable rod 202. This ensures that the longer movable rod 202 is always in a lower position, while the shorter movable rod 202 is in a higher position. The cable is forced to bend in the opposite direction after passing through the upper and lower guide wheels 206, thus offsetting residual stress. When the cable end is fixed, during subsequent cable processing, the cable is continuously pulled, allowing the longer movable rod 202 to move upwards while the shorter movable rod 202 moves downwards, providing additional space for movement and allowing the cable release process to continue.

[0049] It is important to note that cable bending is essentially caused by the outer material of the cable being wound on a spool under tensile stress and the inner material under compressive stress. After release, due to residual elastic deformation, the cable will spring back towards the center of the original spool (i.e., bend inward), a phenomenon known as the "springback effect." Existing technology uses guide rollers to force reverse bending to counteract the residual stress. The guide rollers are arranged in an S-shape, i.e., forward bend → reverse bend → forward bend (alternating in opposite directions).

[0050] Example 2

[0051] like Figure 4 , Figure 5 and Figure 9 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the feeding component includes a base 301, a core column 305 is fixedly connected to the center of the top of the base 301, a hollow column 302 is sleeved on the outside of the core column 305, the hollow column 302 is rotatably connected to the base 301, the sidewalls of the hollow column 302 are symmetrically provided with strip grooves 307, the top view of the strip grooves 307 is cross-shaped, and the interior of each strip groove 307 is slidably connected with a transmission column 308, the transmission column 308 having a rectangular portion 31 that fits into the strip groove 307. 0. The side wall of the core column 305 is provided with a reciprocating spiral groove 309. One end of the transmission column 308 is slidably connected to the reciprocating spiral groove 309. The top of the reciprocating spiral groove 309 is tilted to one side. The ends of the two transmission columns 308 away from the reciprocating spiral groove 309 are fixedly connected to the support plate 303. Two rotating frames 304 are provided and are rotatably connected to the top of the two support plates 303 respectively. The top of the hollow column 302 is provided with a positioning component, which is used to fix the hollow column 302. The top of the hollow column 302 is fixedly connected to the top plate 306.

[0052] Although the solution can replace the reel without stopping the machine, the reel is quite heavy when it is fully wound, making loading very inconvenient and requiring a long installation time. Therefore, relying solely on the stored cables and the movement of the movable rod 202 to provide displacement is insufficient to meet production needs, especially since the old and new cables need to be welded after the reel is replaced.

[0053] In this embodiment, by setting up a feeding component with two stations, the loading of the wire rolls on the other station can begin when the wire is being fed normally at one station. When a change is needed, the loading can be completed by simply switching stations, and then only welding is required.

[0054] The cable reel in the working position and the cable reel in the loading position are located on opposite sides of the reciprocating spiral groove 309, with the height of the cable reel in the working position lower than that in the loading position. During operation, the cable on the cable reel in the working position is released, and the positioning component is unlocked to release the hollow column 302, freeing it from restraint. Since the cable reel in the loading position is fully loaded while the cable reel in the working position is unloaded, the mass of the loading position is greater than that of the working position. Furthermore, because the top of the reciprocating spiral groove 309 is tilted to one side, when the positioning component is unlocked, gravity causes the support plate 30 in the loading position to... 3. Press down and apply a downward force to the transmission column 308, causing the transmission column 308 to slide relative to the spiral groove, driving the hollow column 302 to rotate, thereby driving the support plate 303 of the working position to rotate synchronously until the fully loaded cable reel rotates to the lowest position (i.e., the working position), at which point the unloaded cable reel moves to the highest position (i.e., the loading position), thus completing the automatic switching of the work position. Then, weld the cable lead-out end of the newly replaced cable reel to the cable end fixed by the locked component. After the switching is completed, the control positioning component locks the hollow column 302, and the cable reel in the loading position can be replaced.

[0055] like Figure 4 and Figure 5 As shown, preferably, the positioning assembly includes two cylinders 501 symmetrically fixedly connected to the top of the top plate 306. Two connecting rods 503 are symmetrically slidably connected to the top of the top plate 306. A second piston plate 502 is fixedly connected to the top of the connecting rod 503. The second piston plate 502 is tightly fitted to the inner wall of the cylinder 501. The bottom of the connecting rod 503 extends to the bottom of the top plate 306 and is fixedly connected to the support plate 303. The two cylinders 501 are connected by a retarder tube 504. An electric valve 505 is provided in the middle of the retarder tube 504. The area of ​​the cylinder 501 above the second piston plate 502 and the interior of the retarder tube 504 are filled with hydraulic oil.

[0056] Because the full load of the cable reel has a large mass, there is a large amount of kinetic energy during the switching process of the above-mentioned workstations. Under the impact, the feeding components are easily damaged, such as the large impact between the transmission column 308 and the reciprocating spiral groove 309, which can lead to breakage.

[0057] In this embodiment, the positioning component can lock the hollow rod while limiting the speed of the movement of the support plate 303 and the rotation speed of the hollow column 302, thereby reducing the impact generated during the workstation switching process.

[0058] During operation, the support plates 303 on both sides move in opposite directions, and are pushed by the connecting rod 503 to make the two second piston plates 502 move in opposite directions. This allows hydraulic oil to be squeezed from one cylinder 501 to the other through the upward movement of the second piston plates 502. However, this process is limited by the diameter of the retarder 504, and the hydraulic oil cannot flow quickly. In other words, the movement of the second piston plates 502 is always hindered by the flow speed of the hydraulic oil, thus limiting its movement speed. Furthermore, since the support plates 303 are linked to the second piston plates 502 through the connecting rod 503, the movement speed of the support plates 303 is also hindered. This further limits the rotation speed of the hollow column 302, preventing damage to the equipment caused by excessively rapid station switching.

[0059] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, the driving component includes a drive motor 401, which is fixedly mounted on the base plate of the guide wheel frame 1. The bottom of the central shaft of the rotating frame 304 extends to the bottom of the support plate 303 and has a spline groove 411. A support frame 404 is fixedly connected to the base plate of the guide wheel frame 1. A plurality of slide rods 406 are fixedly connected between the support frame 404 and the base plate of the guide wheel frame 1. A support plate 407 is slidably connected between the slide rods 406. A third spring 408 is sleeved on the outside of the slide rods 406 below the support plate 407. The top of the support frame 404 rotates. A driven gear 403 is connected to the drive motor 401, and a driving gear 402 is fixedly connected to the output end of the drive motor 401. The driving gear 402 meshes with the driven gear 403. The central shaft of the driven gear 403 is hollow and a spline shaft 405 is slidably connected inside. The top end of the spline shaft 405 is engaged with the spline groove 411 by insertion. The bottom of the spline shaft 405 extends to the bottom of the support frame 404 and is fixedly connected to the support plate 407. An iron block 410 is fixedly connected to the bottom of the support plate 407, and an electromagnet 409 is fixedly connected to the bottom plate of the guide wheel frame 1.

[0060] Since the solution uses a dual-station switching method for rapid material loading, and the rotating frame 304 needs to be controlled by the drive component to rotate during the line feeding process, setting up two independent drives will inevitably increase the implementation cost, so it is necessary to improve the drive component.

[0061] In this embodiment, by setting a drive component that can freely detach from and dock with the rotating frame 304, when wire feeding is required, power transmission can be achieved by docking the drive component with the rotating frame 304. When switching workstations, the drive component can be detached from the rotating frame 304, thereby enabling a single drive to meet the rotation requirements of the rotating frame 304 at two workstations.

[0062] When switching workstations, the electromagnet 409 is controlled to work, generating magnetic force to attract the iron block 410 and drive the tray 407 to move downward, squeezing the third spring 408, and at the same time driving the spline shaft 405 to move downward until it leaves the spline groove 411. At this time, the drive component is disengaged from the rotating frame 304, so it will not hinder the workstation switching.

[0063] During cable laying, with the workstation switching completed, the spline shaft 405 is directly facing the spline groove 411 (the weight of the fully loaded cable reel makes the transmission column 308, whose final position after the workstation switching is the working position, exactly at the lowest position of the reciprocating spiral groove 309). The electromagnet 409 is de-energized, causing the electromagnet 409 to lose its magnetism and release the iron block 410. Under the elastic force of the third spring 408, the support plate 407 is pushed to reset and the spline shaft 405 is driven to move upward until the spline shaft 405 is inserted into the spline groove 411, thus completing the docking operation.

[0064] It should be noted that the above-mentioned docking operation does not affect the operation regardless of whether the sides of the spline shaft 405 are aligned with the inner walls of the spline groove 411 (misalignment prevents insertion and docking). Furthermore, even if docking is not completed, it will automatically occur during the wire feeding operation. Specifically, when misaligned, the spline shaft 405 abuts against the end of the central shaft of the rotating frame 304. During wire feeding, the drive motor 401 is controlled to rotate, driving the drive gear 402 to rotate, which in turn drives the driven gear 403 to rotate, causing the spline shaft 405 to rotate. During this process, the spline shaft 405 automatically inserts itself when it is fully aligned with the spline groove 411, subsequently causing the rotating frame 304 to rotate along with the driven gear 403.

[0065] Example 3

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, based on Embodiment 2, the present invention provides a technical solution: preferably, the wire storage component includes a take-up device 801 fixedly installed on the top of the guide wheel frame 1, a guide rod 802 fixedly connected inside the guide wheel frame 1, a traction frame 803 sleeved on the outside of the guide rod 802, the movable part of the take-up device 801 fixedly connected to the traction frame 803, and a traction wheel 804 rotatably connected to the inner side of the traction frame 803.

[0067] In the solution, when the cable reel is released, the workstation needs to be switched to load the cable. However, the end of the previous cable reel begins to lose its winding connection with the reel when the last turn or the last number of turns is insufficient. At this time, the cable end is in a free state and is easily pressed down or tangled by the loading structure when switching workstations.

[0068] In this embodiment, the cable storage component not only stores the cable for temporary use, but also allows for quick retraction of the cable end area to prevent it from being pressed or tangled.

[0069] During normal unwinding, the traction wheel 804 is pulled by the traction action at the production end, causing the traction frame 803 to slide downward and pulling out the movable part on the take-up device 801, where the internal coil spring accumulates potential energy.

[0070] When the cable on the reel is completely released or the remaining cable is insufficient to connect the cable to the reel, the potential energy of the coil spring begins to be released, thereby pulling the traction frame 803 upward and causing the end cable to be pulled quickly. Because the production end is pulled and will not move, the cable end will be pulled away quickly because it is detached from the reel. This achieves cable storage on the one hand and avoids being pressed or tangled by the feeding component on the other.

[0071] Example 4

[0072] like Figure 7 , Figure 8 and Figure 10 As shown, based on Embodiment 3, the present invention provides a technical solution: Preferably, the locking component includes a fixing plate 601, which is fixedly installed on one side of the guide wheel frame 1. A through hole is provided on the fixing plate 601, and a rod 602 is slidably connected inside the through hole. One end of the rod 602 is fixedly connected to a hook 604, and the end of the rod 602 away from the hook 604 extends to the other side of the fixing plate 601 and is fixedly connected to a pad 605. A first spring 606 is sleeved outside the rod 602 and between the pad 605 and the fixing plate 601. A ball bearing 610 is fixedly connected inside the through hole. The external part of the rod 602 has a transmission groove 603, which slides with the ball bearing 610. The part of the transmission groove 603 near the hook 604 is spiral, and the spiral part is wound around the outer wall of the rod 602 to form a spiral transmission structure together with the ball bearing 610. The part of the transmission groove 603 away from the hook 604 is a straight groove. The fixing plate 601 has a buckle structure on the side near the hook 604. The external part of the rod 602 near the hook 604 is fixedly connected to a positioning block 701. The external part of the positioning block 701 has a slot 702. The rod 602 is locked by the buckle structure cooperating with the slot 702.

[0073] In this embodiment, during normal cable feeding, the cable between the reel and the guide wheel set on the side wall of the guide wheel frame 1 is straightened by the traction force. The cable makes a bend at the hook 604 position, causing the hook 604 to move away from the pad 605, which drives the pad 605 to move and squeeze the first spring 606 (this structure is mainly used to monitor whether the cable feeding of the reel is finished).

[0074] At the end of the cable release, the cable end is no longer restrained and therefore insufficient to maintain the corner, allowing the potential energy of the first spring 606 to be released. This pushes the pad 605 back to its original position and causes the hook 604 to move. Initially, the sliding ball 610 is in the straight groove of the transmission groove 603, so the hook 604 moves linearly along with the insertion rod 602. When the sliding ball 610 slides to the spiral part of the transmission groove 603, the continued movement of the insertion rod 602 causes the hook 604 to rotate, thereby winding up the cable end until the latching structure engages with the slot 702 to fix the positioning block 701. At this point, the cable end can no longer be pulled.

[0075] The working principle of a screw drive structure:

[0076] Furthermore, the insertion rod 602 forms a helical transmission engagement with the sliding ball 610 fixed inside the through hole of the fixing plate 601 through the transmission groove 603 opened on its exterior. When the insertion rod 602 moves linearly along the axial direction under the restoring force of the first spring 606, the radial position of the sliding ball 610 remains fixed and exhibits sliding contact with the side wall surface of the transmission groove 603.

[0077] Because the portion of the transmission groove 603 near the hook 604 extends in a spiral shape, this spiral trajectory generates a normal constraint force on the sliding ball 610. According to the principle of kinematic transformation, this constraint force forces the insertion rod 602 to simultaneously rotate around its own axis while undergoing axial displacement. The resulting technical effect is that, through a single axial power source (i.e., spring restoring force), the hook 604 achieves a transformation from linear motion to a composite motion of linear and rotational motion, thereby winding and locking the cable end through the rotational action.

[0078] Preferably, the spiral portion has two turns.

[0079] Since the cable itself passes through the center of the hook 604, it will wrap around the outside of the hook when it rotates. The spiral is set to two turns. Correspondingly, when locking, the hook 604 will rotate two turns. The cable end forms multiple layers of overlapping wrapping around the hook 604, so that the wrap angle formed by the cable on the hook can generate sufficient locking force to ensure that the cable end remains stationary relative to the hook during the wire reel replacement and soldering process.

[0080] like Figure 7 , Figure 8 and Figure 10 As shown, preferably, an air cylinder 607 is fixedly connected to the column on one side of the guide wheel frame 1, and a first piston plate 608 is fixedly connected to the end of the pad block 605 away from the insertion rod 602. The first piston plate 608 is tightly fitted to the inside of the air cylinder 607, and a flow-limiting hole 609 communicating with the outside is opened on the air cylinder 607.

[0081] When the cable is laid to the end of the cable on the reel, it is necessary to use the cable storage component to store the cable on the one hand, and the locking component to fix the end of the cable on the other hand. However, it is necessary to store as much cable as possible before fixing it. Therefore, it is necessary to delay the action time of the locking component.

[0082] In this embodiment, the movement speed of the pad 605 is limited by air pressure, thereby slowing down the movement speed of the insertion rod 602 and the hook 604, so as to provide the cable storage component with sufficient cable storage time.

[0083] During the reset process of the pad 605 (moving away from the insert rod 602), the first piston plate 608 is pushed to move. At this time, the air inside the air cylinder 607 is squeezed out through the flow-limiting hole 609. However, due to the influence of the diameter of the flow-limiting hole 609, the air squeezing speed is limited, which will limit the movement speed of the first piston plate 608. Furthermore, it will limit the movement speed of the pad 605 and the insert rod 602, making the locking process relatively slower, so that the cable end can be locked after the cable storage is completed.

[0084] like Figure 3 and Figure 10 As shown, preferably, the snap-fit ​​structure includes a snap-fit ​​seat 703, which is fixedly connected to the side wall of the fixing plate 601. The snap-fit ​​seat 703 has a through groove 704 that matches the shape of the positioning block 701. A slider 705 is slidably connected between the inner walls of the snap-fit ​​seat 703. A fourth spring 707 is fixedly connected between the top of the slider 705 and the top of the inner wall of the snap-fit ​​seat 703. A wedge 708 is fixedly connected to the bottom plate of the slider 705. The side of the wedge 708 away from the slider 705 has a slope and extends into the interior of the through groove 704. The wedge 708 is slidably connected to the snap-fit ​​seat 703. A toggle groove 706 is provided on one side of the snap-fit ​​seat 703. A lever 709 is fixedly connected to the slider 705. The lever 709 extends to the outside of the snap-fit ​​seat 703 through the toggle groove 706. The snap groove 702 is set as an annular groove.

[0085] When the cable is released, the locking component activates to wrap the end of the cable, and then the latching structure cooperates with the slot 702 to prevent the locking component from being accidentally unlocked due to the cable being pulled.

[0086] After replacing and soldering the reel, by moving the lever 709 upwards, the slider 705 moves upwards, squeezing the fourth spring 707 and causing the wedge block 708 to leave the slot 702, unwinding can begin. During unwinding, the cable at the end hook 604 is straightened, causing the hook 604 to move, which in turn moves the insertion rod 602 and the pad 605, squeezing the first spring 606. At this time, the slot 702 and the wedge block 708 are misaligned, and the lever 709 can be released.

[0087] like Figure 7 and Figure 8 As shown, preferably, a rubber pad 10 is fixedly connected to the outer wall of the hook 604.

[0088] In this embodiment, during normal cable laying, the cable does not contact the outside of the hook 604, so the rubber pad 10 does not affect normal cable laying. When the hook 604 rotates to wrap the cable, the cable is wrapped and tightly attached to the rubber pad 10, which makes the cable and the hook 604 have greater friction, making it less likely to be pulled and improving the stability of the cable end locking.

[0089] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
