Description

Technical Field

[0001] This invention relates to the technical field of cable production, and in particular to a cable production apparatus and method for a charging gun. Background Technology

[0002] During the manufacturing process of charging guns, the cables typically require corrugated tubing to effectively protect the internal conductors using the tubing's flexibility, bending resistance, and pressure resistance. In conventional production processes, to allow multiple conductors to be smoothly threaded into the corrugated tubing, the conductors are usually first twisted together. Then, wrapping tape or extrusion of an outer sheath is applied to the outside of the twisted bundle to constrain the relative positions of the conductors and maintain the bundle's shape. Finally, the entire bundle is threaded into the corrugated tubing.

[0003] To address certain cable design requirements and simplify the production process while optimizing heat dissipation, it is desirable to eliminate the processes of wire stranding, wrapping, or extruding the outer sheath, and instead directly thread multiple loose wires into the corrugated conduit. Eliminating these processes creates more space between the wires and between the wires and the inner wall of the corrugated conduit, facilitating airflow and heat dissipation, thereby improving the current-carrying capacity and safety of the charging gun cable.

[0004] However, in practice, it was found that when multiple loose wires are inserted into the corrugated pipe, because they are in a free and loose independent state, the ends of the wires are very easy to scratch, hook or get stuck on the corrugated protrusions on the inner wall of the pipe, which leads to a significant increase in the resistance to insertion and even makes it impossible to continue inserting, which seriously affects production efficiency and product quality. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cable production device for a charging gun, which can significantly reduce the resistance of pipe insertion, avoid pipe insertion interruption, and greatly improve production efficiency and yield.

[0006] The present invention also proposes a method for producing a cable production apparatus having the above-mentioned charging gun.

[0007] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a cable comprising multiple conductors and a corrugated tube, wherein the multiple conductors are disposed within the corrugated tube. The production apparatus includes: a cutting mechanism for cutting the multiple conductors to a predetermined length; a stripping mechanism disposed at the outlet end of the cutting mechanism for stripping the ends of the multiple conductors; a conveying mechanism including multiple conveying modules, each of which is used to convey the stripped multiple conductors; and a guiding mechanism including a guide and a hub, wherein the guide is connected to the hub for guiding the multiple conductors into the hub, wherein the hub accommodates the multiple conductors through which they pass and arranges the multiple conductors in a loop shape; and a threading mechanism. The device includes a support tube and a tube insertion assembly. The support tube matches the inner side of the corrugated pipe. The tube insertion assembly drives the corrugated pipe to fit onto the support tube, so that the support tube supports the corrugated pipe. A tube shifting mechanism drives the support tube to move, so that the end of the support tube aligns with the end of the hub. A wire insertion mechanism includes a wire clamping assembly and a tube pressing assembly. The wire clamping assembly is connected to the tube shifting mechanism and is movably disposed inside the support tube. The wire clamping assembly engages with the inner wall of the support tube to clamp multiple wires. The tube pressing assembly abuts against the outer periphery of the corrugated pipe. The tube shifting mechanism drives the wire clamping assembly and the support tube to move synchronously, so that multiple wires are inserted into the corrugated pipe.

[0008] A cable production apparatus for a charging gun according to an embodiment of the present invention has at least the following beneficial effects: 1. The present invention provides a cutting mechanism and a stripping mechanism. The cutting mechanism cuts multiple wires to a preset length, and then the stripping mechanism strips the insulation from the ends of the multiple wires. This avoids the current process of stripping the insulation after the wires are inserted into the corrugated pipe, greatly reducing the difficulty of stripping the insulation from the cable wires and improving the automation level of the equipment and the production efficiency of the cable.

[0009] 2. This invention, by setting up a conveying mechanism and a guiding mechanism, uses multiple conveying modules to convey multiple stripped wires. The guide mechanism guides the multiple wires into the hub. The hub in the guiding mechanism pre-arranges the multiple loose wires into a ring shape, so that the wires maintain an orderly spatial distribution before entering the support tube and the corrugated tube. This makes the arrangement of the multiple wires match the space of the inner circular hole of the support tube, reducing the friction generated when multiple wires pass through the support tube, and allowing the ends of the wires to pass smoothly into the support tube.

[0010] 3. By setting up a tube-passing mechanism, the present invention uses a support tube to rigidly support the inner wall of the corrugated pipe, which effectively eliminates the unevenness of the inner wall of the corrugated pipe, avoids the ends of multiple wires from directly contacting the inner wall of the corrugated pipe, and avoids the problems of the ends of the wires scraping, hooking, and getting stuck with the corrugated protrusions.

[0011] 4. This invention, by setting up a tube-moving mechanism and a wire-threading mechanism, utilizes the wire-clamping component in the wire-threading mechanism to clamp the wire in cooperation with the inner wall of the support tube, and the tube-pressing component to press against the outer periphery of the corrugated tube. Then, the tube-moving mechanism drives the wire-clamping component and the support tube to move synchronously, so that the wire is smoothly transferred into the corrugated tube. This solves the problem that when loose wires are directly threaded through the tube, the ends or middle parts are easily scratched, hooked, or stuck with the corrugated protrusions. It significantly reduces the tube-threading resistance, avoids tube-threading interruption, and greatly improves production efficiency and yield.

[0012] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a clamping assembly comprising a pressure block and a first cylinder. The pressure block is movable along the axial direction of the support tube. The first cylinder is used to drive the pressure block to move. The pressure block is used to press multiple wires against the inner wall of the support tube. The outer side of the pressure block has a conical surface, and the interior of the support tube is provided with a conical wall. The conical surface and the conical wall are capable of clamping multiple wires.

[0013] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a tube-moving mechanism that drives a support tube to approach a tube-passing assembly, such that the end of the support tube is opposite to the end of the corrugated tube. The tube-passing assembly includes an upper conveying wheel group and a lower conveying wheel group, which are capable of fitting the corrugated tube onto the support tube. The upper conveying wheel group includes an upper roller and a second cylinder for driving the upper roller to rise and fall. The outer periphery of the upper roller is used to abut against the corrugated tube. The upper roller is provided with a pressure sensor for detecting the pressure of the upper roller abutting against the corrugated tube. The lower conveying wheel group includes a lower roller and a motor for driving the lower roller to rotate. The lower roller and the upper roller cooperate to convey the corrugated tube.

[0014] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a guide having a plurality of guide holes distributed to allow a plurality of wires to pass through, the cross-sectional size of the guide holes being gradually reduced along the direction close to the hub, a plurality of conveying modules corresponding one-to-one with the plurality of guide holes, and the hub having a plurality of limiting holes arranged circumferentially, the plurality of limiting holes communicating with the plurality of guide holes respectively.

[0015] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a tube transfer mechanism comprising a first translation module and a second translation module. The first translation module is connected to the second translation module, and the second translation module is connected to the support tube. The first translation module is used to drive the support tube to move between the tube insertion assembly and the tube pressing assembly. After the wire clamping assembly clamps a plurality of the wires, the second translation module is used to drive the support tube to move along a side away from the hub.

[0016] According to a first aspect of the present invention, a cable production apparatus for a charging gun further includes a receiving mechanism, the receiving mechanism including a wiring groove and a third translation module, the wiring groove being used to receive a processed cable, the third translation module being connected to the wiring groove, and when the pressing tube assembly abuts against the corrugated tube, the third translation module driving the wiring groove closer to the underside of the support tube to receive the corrugated tube detached from the support tube.

[0017] According to a first aspect of the present invention, a cable production apparatus for a charging gun includes a crimping assembly located above the wiring groove, the crimping assembly and the wiring groove being capable of clamping the corrugated pipe; the crimping assembly includes an upper pressure plate and a third cylinder for driving the upper pressure plate to rise and fall, the bottom of the upper pressure plate matching the corrugations on the outer periphery of the corrugated pipe for abutting against the outer periphery of the corrugated pipe.

[0018] The present invention also provides a cable manufacturing method, which has the above-mentioned beneficial effects.

[0019] According to a second aspect of the present invention, a cable manufacturing method is applied to a cable manufacturing apparatus for a charging gun as described in any one of the above claims. The cable manufacturing method includes: a wire processing step, wherein a cutting mechanism is used to cut multiple wires to a predetermined length, and then a stripping mechanism is used to strip the ends of the multiple wires of the predetermined length; a wire threading step, wherein multiple conveying modules are used to convey the stripped multiple wires, such that the multiple wires are respectively threaded into the interior of a guide, the guide guiding the multiple wires into the interior of a hub, such that the multiple wires are arranged in a loop shape; and a tube threading step, wherein a tube moving mechanism is used to drive a support tube closer to the tube threading assembly, such that the end of the support tube is aligned with the... The ends of the corrugated pipe are aligned, and the corrugated pipe is conveyed using the pipe-passing assembly so that the entire corrugated pipe is fitted onto the support pipe. In the wire-pulling step, the support pipe is driven closer to the hub using the pipe-moving mechanism so that the end of the support pipe is aligned with the outlet end of the hub. The wire is moved using the conveying module so that the wire passes through the interior of the support pipe. Multiple wires are clamped by the wire-clamping assembly in cooperation with the inner wall of the support pipe, and the pipe-pressing assembly abuts against the outer periphery of the corrugated pipe. Then, the wire-clamping assembly and the support pipe are moved away from the hub using the pipe-moving mechanism, and the corrugated pipe detaches from the support pipe, allowing multiple wires to pass through the corrugated pipe.

[0020] According to a second aspect of the present invention, a cable manufacturing method includes a tube-moving mechanism that drives a support tube closer to a tube-insertion assembly, such that the end of the support tube is opposite to the end of the corrugated pipe. The tube-insertion assembly includes an upper conveying wheel group and a lower conveying wheel group, which are capable of fitting the corrugated pipe onto the support tube. The upper conveying wheel group includes an upper roller and a second cylinder for driving the upper roller to rise and fall. The outer periphery of the upper roller is used to abut against the corrugated pipe. The upper roller is equipped with a pressure sensor for detecting the pressure of the upper roller abutting against the corrugated pipe. The lower conveying wheel group includes a lower roller and a motor for driving the lower roller to rotate. The lower roller and the upper roller cooperate to convey the corrugated pipe. In this step, the corrugated pipe is placed between the upper roller and the lower roller. The second cylinder drives the upper roller to descend, causing the upper roller and the lower roller to clamp the corrugated pipe. The pressure sensor detects the pressure of the upper roller pressing against the corrugated pipe, and obtains the current pressure value of the upper roller. Based on the preset pressure value of the upper roller, the current pressure value of the upper roller is compared with the preset pressure value of the upper roller to adjust the descending position of the upper roller, so that the end of the corrugated pipe tends to be round, so that the end of the support tube is aligned with the end of the corrugated pipe. Then, the motor drives the lower roller to rotate, so that the lower roller and the upper roller convey the corrugated pipe, so that the corrugated pipe is fitted onto the support tube.

[0021] According to a second aspect of the present invention, a cable manufacturing method further includes a receiving mechanism, the receiving mechanism comprising a wiring groove and a third translation module. The wiring groove is used to receive the processed cable, and the third translation module is connected to the wiring groove. When the second translation module drives the support tube to move, the third translation module drives the wiring groove closer to the underside of the support tube to receive the corrugated tube detached from the support tube. In the cable pulling step, the wire clamping assembly clamps a plurality of the wires, the tube pressing assembly abuts against the outer periphery of the corrugated tube, and the third translation module drives the wiring groove closer to the underside of the support tube. Then, the second translation module drives the support tube to move along a side away from the hub, the wire clamping assembly follows the movement of the support tube, the plurality of the wires pass into the corrugated tube, and simultaneously, the corrugated tube gradually detaches from the support tube and gradually falls onto the wiring groove until the entire corrugated tube falls onto the wiring groove. The third translation module drives the wiring groove away from the support tube to move the entire cable out of the processing position.

[0030] The following describes, with reference to the accompanying drawings, a cable production apparatus and method for a charging gun according to an embodiment of the present invention.

[0031] The present invention aims to provide an embodiment of a cable production apparatus and production method for a charging gun.

[0032] A charging gun cable according to an embodiment of the present invention includes multiple conductors 1 and a corrugated tube 2, wherein the multiple conductors 1 are disposed inside the corrugated tube 2.

[0033] Specifically, the multiple conductors 1 are power lines, control lines, signal lines, ground lines, and power lines, respectively, to meet the functional requirements of the charging gun cable. According to design requirements, the cable also includes a liquid cooling pipe, which is housed within the corrugated pipe 2 to improve the cable's heat dissipation capacity.

[0034] It should be noted that the insulation layer of power lines and control lines can be made of cross-linked PE or rubber, while the insulation layer of signal lines can be made of fluoroplastics.

[0035] Understandably, this cable structure allows for a larger airflow gap between conductors 1 and between conductor 1 and the inner wall of the corrugated tube 2, effectively optimizing the heat dissipation performance of the charging gun cable, thereby improving the cable's current carrying capacity and long-term safety. Furthermore, the cable's wireless extrusion outer sheath reduces manufacturing costs.

[0036] An embodiment of the present invention provides a cable production apparatus for a charging gun, with reference to... Figure 1 It includes a cutting mechanism 3, a peeling mechanism 4, a conveying mechanism, a guiding mechanism, a tube threading mechanism, a tube transfer mechanism, and a threading mechanism.

[0037] The cutting mechanism 3 is used to cut multiple wires 1 to a preset length. The cutting mechanism 3 includes a cutting table, a cutting blade and a power source. The power source drives the cutting blade to move, and the cutting blade and the cutting table cooperate to cut the wires 1.

[0038] The stripping mechanism 4 is located at the wire exit end of the cutting mechanism 3 and is used to strip the insulation from the ends of multiple wires 1. The stripping mechanism 4 includes a first stripping blade, a second stripping blade, and a power source. The power source drives the second stripping blade to move. The first and second stripping blades have cutting edges that match the wires 1. The first and second stripping blades peel off the outer sheath of the wires 1 through the cutting edges to expose the metal conductor. Specifically, a wire transfer mechanism can be provided between the cutting mechanism 3 and the stripping mechanism 4. The wire transfer mechanism is used to transfer the cut wire 1 to the stripping mechanism 4.

[0039] It is understood that this embodiment sets up a cutting mechanism 3 and a stripping mechanism 4. The cutting mechanism 3 cuts multiple wires 1 to a preset length. Then, the stripping mechanism 4 strips the ends of multiple wires 1, avoiding the process of stripping the wires 1 after they are inserted into the corrugated pipe 2. This greatly reduces the difficulty of stripping the wires 1 of the cable and helps to improve the automation level of the equipment and improve the production efficiency of the cable.

[0040] For conveying mechanisms, refer to Figure 1 The conveying mechanism includes multiple conveying modules 5, which are used to convey multiple stripped wires 1 respectively.

[0041] Specifically, the conveying module 5 includes an upper guide wheel, a lower guide wheel, and a motor that drives the upper or lower guide wheel to rotate. The upper and lower guide wheels clamp the conveying wire 1.

[0042] The guiding mechanism includes a guide 6 and a hub 7. The guide 6 is connected to the hub 7 and is used to guide multiple wires 1 into the hub 7. The hub 7 houses the multiple wires 1 and arranges them into a loop shape.

[0043] It is understood that in this embodiment, by setting up a conveying mechanism and a guiding mechanism, multiple conveying modules 5 are used to convey multiple stripped wires 1 respectively. The guide 6 in the guiding mechanism guides the multiple wires 1 into the hub 7. The hub 7 in the guiding mechanism arranges the multiple loose wires 1 into a ring shape in advance, so that the wires 1 maintain an orderly spatial distribution before entering the support tube 8 and the corrugated tube 2. This makes the arrangement of the multiple wires 1 match the space of the inner circular hole of the support tube 8, reducing the friction generated when the multiple wires 1 pass through the support tube 8, and allowing the ends of the wires 1 to pass smoothly into the support tube 8.

[0044] For pipe-insertion mechanisms, refer to Figure 1 The tube insertion mechanism includes a support tube 8 and a tube insertion assembly 9. The support tube 8 matches the inner side of the corrugated pipe 2, and the tube insertion assembly 9 is used to drive the corrugated pipe 2 to be sleeved on the support tube 8, so that the support tube 8 supports the corrugated pipe 2.

[0045] It is understood that by setting up a tube-passing mechanism, the tube-passing mechanism uses the support tube 8 to rigidly support the inner wall of the corrugated pipe 2, effectively eliminating the unevenness of the corrugated inner wall, avoiding direct contact between the ends of multiple wires 1 and the inner wall of the corrugated pipe 2, and avoiding the problems of scraping, hooking, and jamming between the ends of the wires 1 and the corrugated protrusions.

[0046] It should be noted that the end of the support tube 8 is provided with a chamfer or rounded surface, which is used to guide the support tube 8 into the corrugated tube 2.

[0047] In some specific embodiments of the present invention, reference is made to... Figure 4 and Figure 7 The guide 6 has multiple guide holes 20, which are distributed to allow multiple wires 1 to pass through. The cross-sectional size of the guide holes 20 is gradually reduced along the direction close to the hub 7. Multiple conveying modules 5 correspond one-to-one with the multiple guide holes 20. The hub 7 has multiple limiting holes 21, which are arranged circumferentially and are connected to the multiple guide holes 20 respectively.

[0048] Understandably, the guide holes 20 with gradually narrowing cross-sections on the guide 6 can guide and gather the loose wires 1 from different conveying modules 5 in a gradual manner, reducing the bending and jumping of the wires 1 during their journey. The multiple limiting holes 21 arranged circumferentially on the hub 7 ensure that the wires 1 are ultimately and accurately positioned into a ring array, guaranteeing that multiple loose wires 1 can enter the subsequent support tube 8 in an orderly and smooth manner, and be evenly distributed on the circumference. This provides an ideal arrangement of wires 1 for the subsequent clamping of wires 1, and also ensures that the wires 1 maintain a regular annular gap within the corrugated tube 2, maximizing the use of the internal space of the corrugated tube 2 for heat dissipation, and avoiding uneven heat dissipation or excessive outer diameter caused by local accumulation of wires 1 inside the tube.

[0049] For transfer agencies, refer to Figure 1 The tube-moving mechanism is used to drive the support tube 8 to move so that the end of the support tube 8 is connected to the end of the hub 7.

[0050] In some specific embodiments of the present invention, reference is made to... Figure 5 The pipe-moving mechanism drives the support pipe 8 to approach the pipe-passing assembly 9, so that the end of the support pipe 8 is opposite to the end of the corrugated pipe 2. The pipe-passing assembly 9 includes an upper conveying wheel group 15 and a lower conveying wheel group 16, which can fit the corrugated pipe 2 onto the support pipe 8. The upper conveying wheel group 15 includes an upper roller 17 and a second cylinder 18 that drives the upper roller 17 to rise and fall. The outer periphery of the upper roller 17 is used to abut against the corrugated pipe 2. The upper roller 17 is equipped with a pressure sensor, which is used to detect the pressure of the upper roller abutting against the corrugated pipe 2. The lower conveying wheel group 16 includes a lower roller 19 and a motor that drives the lower roller to rotate. The lower roller 19 and the upper roller 17 cooperate to convey the corrugated pipe 2.

[0051] Understandably, by cooperating with the upper conveyor wheel group 15 and the lower conveyor wheel group 16, and by using the lower roller 19 and the upper roller 17 to transport the corrugated pipe 2, the automatic connection of the corrugated pipe 2 to the support pipe 8 is achieved.

[0052] By installing a pressure sensor on the upper roller 17, the pressure of the upper roller 17 pressing against the bellows 2 can be detected in real time. The stroke of the second cylinder 18 can be adjusted by the feedback of the pressure sensor to avoid the bellows 2 from being deformed due to excessive pressure on the upper roller 17. The bellows 2 port can be moderately pressed to be close to a circle, ensuring that the end of the support tube 8 can be smoothly and without impact aligned with the bellows 2 port and inserted, avoiding connection failure or damage to the bellows 2 caused by port deformation.

[0053] The threading mechanism includes a wire clamping assembly and a tube pressing assembly 10. The wire clamping assembly is connected to the tube moving mechanism and can be movably disposed inside the support tube 8. The wire clamping assembly is used to clamp multiple wires 1 in cooperation with the inner wall of the support tube 8. The tube pressing assembly 10 is used to abut against the outer periphery of the corrugated tube 2. The tube moving mechanism can drive the wire clamping assembly and the support tube 8 to move synchronously, so that multiple wires 1 are threaded into the corrugated tube 2.

[0054] It is understood that this embodiment, by setting up a tube-moving mechanism and a wire-threading mechanism, utilizes the wire clamping component in the wire-threading mechanism to clamp the wire 1 in cooperation with the inner wall of the support tube 8, and the tube pressing component 10 to abut against the outer periphery of the corrugated tube 2. Then, the tube-moving mechanism drives the wire clamping component and the support tube 8 to move synchronously, so that the wire 1 is smoothly transferred into the corrugated tube 2. This solves the problem that the ends or middle of the existing scattered wires 1 are easily scratched, hooked, or stuck with the corrugated protrusions when directly threading through the tube. It significantly reduces the resistance to threading through the tube, avoids interruption of threading through the tube, and greatly improves production efficiency and yield.

[0055] In some specific embodiments of the present invention, the pressure tube assembly 10 is located above the wiring groove 24, and the pressure tube assembly 10 and the wiring groove 24 can clamp the bellows 2; the pressure tube assembly 10 includes an upper pressure plate 26 and a third cylinder 27 for driving the upper pressure plate 26 to rise and fall, the bottom of the upper pressure plate 26 matches the corrugations on the outer periphery of the bellows 2, and is used to abut against the outer periphery of the bellows 2.

[0056] Understandably, by using the third cylinder 27 to drive the upper pressure plate 26 to descend, the upper pressure plate 26 and the wiring groove 24 can firmly hold the end of the bellows 2 from both the top and bottom by matching the contour of the surface of the upper pressure plate 26 with the outer corrugations of the bellows 2. This corrugated matching clamping not only increases the contact area and friction, effectively preventing the bellows 2 from moving axially when pulling the wire, but also does not flatten or damage the corrugated structure of the bellows 2. It can reliably fix the bellows 2, realize the wire 1 to be inserted without damage, and ensure that the relative movement between the wire 1 and the bellows 2 is safe and stable.

[0057] In some specific embodiments of the present invention, reference is made to... Figure 6 The wire clamping assembly includes a pressure block 11 and a first cylinder 12. The pressure block 11 can move along the axial direction of the support tube 8. The first cylinder 12 is used to drive the pressure block 11 to move. The pressure block 11 is used to press multiple wires 1 against the inner wall of the support tube 8. The outer side of the pressure block 11 has a conical surface 13. The inside of the support tube 8 is provided with a conical wall 14. The conical surface 13 and the conical wall 14 can clamp multiple wires 1.

[0058] Understandably, the first cylinder 12 drives the pressure block 11 with a conical surface 13. The pressure block 11 with a conical surface 13 cooperates with the conical wall 14 inside the support tube 8 to clamp the end of the wire 1. This conical surface clamping method has a self-centering function, which can apply a uniform and stable radial clamping force to the multiple wires 1 that are already distributed in a ring, ensuring that all wires 1 are firmly fixed on the inner wall of the support tube 8 and will not slip or misalign. Moreover, when the tube moving mechanism is pulled, the wire 1 can move synchronously with the support tube 8, avoiding the problem of wire 1 being pulled out or piled up due to poor clamping, ensuring the continuity and reliability of tube insertion, and the structure is simple and the action response is fast.

[0059] In some specific embodiments of the present invention, reference is made to... Figure 6 A wire splitter is provided at one end of the support tube 8 near the hub 7. The wire splitter has multiple wire splitting holes 29, which are distributed around the circumference of the support tube 8. Each wire splitting hole 29 corresponds to one of the limiting holes 21. Each wire 1 is inserted into one wire splitting hole 29. Thus, after the pressure block 11 presses multiple wires 1 against the inner circumference of the support tube 8, the multiple wires 1 are distributed around the circumference, ensuring that each wire 1 can be pressed tightly.

[0060] In some specific embodiments of the present invention, reference is made to... Figure 3 and Figure 4 The tube transfer mechanism includes a first translation module 22 and a second translation module 23. The first translation module 22 is connected to the second translation module 23, and the second translation module 23 is connected to the support tube 8. The first translation module 22 is used to drive the support tube 8 to move between the tube insertion assembly 9 and the tube pressing assembly 10. After the wire clamping assembly clamps multiple wires 1, the second translation module 23 is used to drive the support tube 8 to move along the side away from the hub 7.

[0061] It is understandable that by setting up the first translation module 22 and the second translation module 23, the first translation module 22 drives the support tube 8 to move between the tube threading station and the wire threading station, and the second translation module 23 drives the support tube 8 to perform a precise wire pulling action, making the overall layout of the equipment more flexible and compact, with each action not interfering with the others. Moreover, the second translation module 23 can provide a stable and precisely controllable stroke for wire pulling, ensuring that the corrugated tube 2 is smoothly peeled off from the support tube 8 and the wire 1 is evenly threaded in, thereby improving the stability and production efficiency of the equipment.

[0062] It should be noted that the first translation module 22 and the second translation module 23 can be linear motor modules, and no specific limitation is made here.

[0063] In some specific embodiments of the present invention, reference is made to... Figure 3 and Figure 4It also includes a receiving mechanism, which includes a wiring groove 24 and a third translation module 25. The wiring groove 24 is used to receive the processed cable. The third translation module 25 is connected to the wiring groove 24. When the pressure tube assembly 10 abuts against the corrugated tube 2, the third translation module 25 drives the wiring groove 24 to move closer to the bottom of the support tube 8 to receive the corrugated tube 2 that has detached from the support tube 8.

[0064] Understandably, while the second translation module 23 drives the support tube 8 to move, causing the corrugated pipe 2 to gradually detach from the support tube 8, the third translation module 25 drives the wiring slot 24 to move synchronously below the support tube 8. This supports and lifts the gradually emerging finished cable, effectively preventing the tension and bending stress on the corrugated pipe 2 and conductor 1 that have not yet completely detached from the support tube 8 due to the cable's own weight. This avoids uneven stress on the conductor 1 or deformation of the corrugated pipe 2's end, ensuring a smooth installation process and maintaining the integrity of the finished cable. After installation, the wiring slot 24 can automatically move out, facilitating unloading and further improving the automation level of the device and the neatness of the finished product collection.

[0065] Specifically, the receiving trough has a semi-circular cross-section to facilitate cable reception.

[0066] Furthermore, refer to Figure 4 The receiving mechanism also includes a fourth cylinder 28, a third moving module connected to the fourth cylinder 28, and the telescopic end of the fourth cylinder 28 connected to the receiving groove for driving the receiving groove to rise and fall.

[0067] It should be noted that the third translation module 25 can be a linear motor module, and no specific limitation is made here.

[0068] In some specific embodiments of the present invention, the support mechanism further includes a position detection sensor, which is disposed at the end of the wiring groove 24 away from the hub 7, and is used to detect the position of the support tube 8.

[0069] Understandably, the second translation module 23 drives the support tube 8 to move along the side away from the hub 7, and the wire clamping assembly moves with the support tube 8. Multiple wires 1 pass through the corrugated pipe 2, and the detection sensor can detect the position of the support tube 8. When the corrugated pipe 2 falls completely into the wiring slot 24 and the position of the support tube 8 can no longer be detected, the second translation module 23 is controlled to stop moving, and the wire clamping assembly is controlled to release the clamping of the wires 1, ensuring that the position of the wires 1 passing through the corrugated pipe 2 is consistent each time.

[0070] This embodiment also proposes a cable manufacturing method, applied to the cable manufacturing apparatus for the aforementioned charging gun, referring to... Figure 8 Cable manufacturing methods include: In the wire processing steps, the cutting mechanism 3 is used to cut multiple wires 1 to a preset length, and then the stripping mechanism 4 is used to strip the ends of the multiple wires 1 of the preset length.

[0071] In the threading step, multiple conveying modules 5 are used to convey multiple stripped wires 1, so that the multiple wires 1 are threaded into the interior of the guide, and the guide guides the multiple wires 1 into the interior of the hub 7, so that the multiple wires 1 are arranged in a loop shape.

[0072] In the tube insertion step, the tube moving mechanism is used to drive the support tube 8 close to the tube insertion assembly 9, so that the end of the support tube 8 is aligned with the end of the corrugated tube 2. The tube insertion assembly 9 is used to transport the corrugated tube 2, so that the entire corrugated tube 2 is fitted onto the support tube 8.

[0073] In the cable pulling step, the support tube 8 is driven close to the hub 7 using the tube moving mechanism, so that the end of the support tube 8 is aligned with the cable outlet end of the hub 7. The wire 1 is driven to move using the conveying module 5, so that the wire 1 passes into the interior of the support tube 8. The multiple wires 1 are clamped by the wire clamping assembly and the inner wall of the support tube 8. The tube pressing assembly 10 is used to abut against the outer periphery of the corrugated tube 2. Then, the tube moving mechanism can drive the wire clamping assembly and the support tube 8 to move away from the hub 7, so that the corrugated tube 2 is disengaged from the support tube 8, allowing the multiple wires 1 to pass into the corrugated tube 2.

[0074] Understandably, the above method includes wire processing, threading, tube threading, and wire pulling steps. First, the scattered wires 1 are organized into a ring shape using the guiding mechanism and conveying module 5. Then, the corrugated tube 2 is supported from the inside using the support tube 8. Finally, with the corrugated tube 2 fixed by the tube pressing assembly 10, the wire clamping assembly and the tube moving mechanism work together to smoothly pull the wires 1 into the corrugated tube 2. This avoids the scraping and jamming of the wire 1 end against the inner wall of the corrugated tube 2 when it is pushed in. This allows scattered multi-strand wires 1 that cannot be threaded into the tube using conventional methods to be efficiently and successfully threaded into the corrugated tube 2. Moreover, it ensures product quality and simplifies the upstream process.

[0075] In some specific embodiments of the present invention, during the pipe threading step, the corrugated pipe 2 is placed between the upper roller 17 and the lower roller 19. The second cylinder 18 drives the upper roller 17 to descend, so that the upper roller 17 and the lower roller 19 clamp the corrugated pipe 2. A pressure sensor is used to detect the pressure of the upper roller 17 pressing the corrugated pipe 2, and the current pressure value of the upper roller 17 is obtained. According to the preset pressure value of the upper roller 17, the current pressure value of the upper roller 17 is compared with the preset pressure value of the upper roller 17 to adjust the descending position of the upper roller 17 so that the end of the corrugated pipe 2 tends to be circular, so that the end of the support tube 8 is aligned with the end of the corrugated pipe 2. Then, the motor drives the lower roller 19 to rotate, so that the lower roller 19 and the upper roller 17 convey the corrugated pipe 2 so that the corrugated pipe 2 is fitted onto the support tube 8.

[0076] It should be noted that when the corrugated pipe 2 is inserted, the support pipe 8 enters between the upper roller 17 and the lower roller 19, so that the corrugated pipe 2 can be completely fitted onto the support pipe 8.

[0077] Understandably, by incorporating a feedback mechanism that uses a pressure sensor to monitor the pressure of the upper roller 17 and adjust the roller's downward pressure position, the ends of corrugated pipes 2 from different batches or with slight deformation can be precisely shaped into circles suitable for insertion into the support tube 8. This method, using pressure as a benchmark, achieves flexible adaptation to corrugated pipes 2 of different materials and wall thicknesses, avoiding problems such as unresponsive ends or insufficient compression caused by relying on experience or fixed position control. This significantly improves the intelligence level and success rate of the pipe threading process, ensuring smooth connection between the support tube 8 and the corrugated pipe 2, and laying the foundation for accurate subsequent wire pulling.

[0078] In some specific embodiments of the present invention, during the cable pulling step, the clamping assembly clamps multiple conductors 1, the pressing assembly abuts against the outer periphery of the corrugated pipe 2, and the third translation module 25 drives the wiring groove 24 to approach the lower part of the support pipe 8; then, the second translation module 23 drives the support pipe 8 to move along the side away from the hub 7, the clamping assembly moves with the support pipe 8, the multiple conductors 1 pass into the corrugated pipe 2, and at the same time, the corrugated pipe 2 gradually detaches from the support pipe 8 and gradually falls into the wiring groove 24 until the entire corrugated pipe 2 falls into the wiring groove 24; the third translation module 25 drives the wiring groove 24 away from the support pipe 8 so that the entire cable moves out of the processing position.

[0079] Understandably, the addition of a supporting mechanism during the cable pulling process allows the corrugated pipe 2 to gradually detach from the support pipe 8 and wrap around the conductor 1 as the support pipe 8 moves away from the hub 7. Simultaneously, the wiring groove 24, driven by the third translation module 25, moves synchronously to the bottom of the support pipe 8 to receive the corrugated pipe 2. This ensures that the entire corrugated pipe 2 is evenly supported by the wiring groove 24 throughout the process of detaching from the support pipe 8. This solves the problem that the corrugated pipe 2 port may get stuck with the support pipe 8 due to the bending caused by the weight of the long cable, resulting in sudden changes in the resistance of pulling out the conductor 1 and even damage to the insulation layer of the conductor 1. This makes the installation process of long cables smoother and safer, and the finished cable is straight and stress-free, further improving production continuity.

[0080] It should be noted that after the clamping assembly clamps multiple wires 1, the second translation module 23 drives the support tube 8 to move along the side away from the hub 7, so that a moving distance is generated between the hub 7 and the support tube 8. Then, the support tube 8 stops moving. Then, the clamping assembly abuts against the corrugated tube 2, and the second translation module 23 continues to drive the support tube 8 to move along the side away from the hub 7 until the wires 1 are completely detached from the hub 7.
