[0002] In the field of wire processing and production, wire end bending, fixed-length cutting, and insulation stripping are routine core processes in wire harness processing, widely used in the mass production of various electrical components and wire harness assemblies. Existing conventional wire processing equipment generally adopts a split-type independent operation structure, setting wire conveying, wire bending, wire cutting, wire transfer, and wire stripping processes at different equipment stations. These processing devices are independent of each other, and the operational correlation is weak. Summary of the Invention

[0003] The present invention aims to improve at least one technical problem in the prior art.

[0004] This invention provides a dual-wire fixed-length conveying and processing device, comprising: a main unit and a wire feeding module, a bending module, a cutting module, a stripping module, and a wire transport module, all disposed on the main unit. The wire feeding module is used to convey the wire to the bending module, the bending module is used to bend the wire into a U-shaped wire, the cutting module is used to cut the U-shaped wire obtained after bending, the wire transport module is used to transport the cut U-shaped wire to the stripping module, and the stripping module is used to strip the insulation from the ends of the wire.

[0005] As a sub-solution of the above technical solution, the wire feeding module includes several pairs of wire straightening rollers, wire feeding rollers, and wire feeding tubes. The wire straightening rollers are used to straighten the wires, and the wire feeding rollers are used to feed the straightened wires to the wire feeding tubes.

[0006] As a sub-solution of the above technical solution, the bending module includes a bending motor, a bending connecting platform, and bending clamps. The bending motor is mounted on the frame and is drivenly connected to the bending connecting platform. The bending clamps are located on one side of the bending connecting platform and are used to clamp one end of the wire. The straightened wire extends out from the wire feed tube. The bending clamps first clamp one end of the wire, and then the bending motor drives the bending connecting platform to rotate, at which point the wire is bent into a U-shaped wire.

[0009] As a sub-solution of the above technical solution, the stripping module further includes a wire core stripping damage prevention detection component. This component detects whether the blades of the first and / or second stripping blades contact the wire core of the U-shaped conductor. The wire core is the conductor of the U-shaped conductor; if the first and / or second stripping blades strip the wire core, the performance of the wire will be reduced. In this embodiment, the wire core stripping damage prevention detection component uses current detection. Specifically, it is connected in series with the first and second stripping blades in a wire core stripping damage prevention circuit with a power supply. By detecting changes in the current in this circuit, it is determined whether the first and second stripping blades have contacted the wire core during the stripping process.

Detailed Implementation

[0016] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The following is combined with Figures 1 to 5 Embodiments of the present invention will be described.

[0018] In existing wire processing equipment, most adopt a split processing structure. The wire conveying, bending, cutting, stripping and handling processes are independent of each other, and the connection between each process is poor. The manual transfer of wires not only increases the workload, but also easily leads to deviations in wire processing position and inconsistent processing specifications. The overall automation level and processing efficiency are low.

[0019] This embodiment provides a dual-wire fixed-length conveying and processing device, which can realize integrated continuous processing of conductors and effectively improve the above-mentioned problems. The dual-wire fixed-length conveying and processing device includes a main unit 1 and a wire feeding module 2, a bending module 3, a cutting module 4, a stripping module 5, and a conductor transport module 6, all of which are installed on the main unit 1. The wire feeding module 2 is used to convey the conductor to the bending module 3, the bending module 3 is used to bend the conductor into a U-shaped conductor, the cutting module 4 is used to cut the U-shaped conductor obtained after bending, and the conductor transport module 6 is used to transport the cut U-shaped conductor to the stripping module 5, the stripping module 5 is used to strip the insulation from the ends of the conductor. This device achieves fully automated operation of conductor conveying, bending, cutting, transporting, and stripping through the coordinated cooperation of each module, effectively improving the problems of poor process connection, low processing efficiency, and poor product processing consistency in traditional split processing, and improving the automation level and overall processing quality of dual-wire fixed-length conductor processing.

[0020] In existing wire feeding structures, unstraightened wires are bent or twisted. Directly feeding them to the bending station results in poor bending accuracy and makes it difficult to precisely control the wire feeding length, thus failing to meet the requirements for fixed-length processing. Furthermore, in one embodiment of the present invention, the wire feeding module 2 includes several pairs of straightening rollers 21, feeding rollers 22, and feeding tubes 23. The straightening rollers 21 are used to straighten the wires, and the feeding rollers 22 are used to feed the straightened wires to the feeding tubes 23. One end of the feeding tubes 23 leads to the bending module 3, and the wire feeding assembly is also used to feed one end of the U-shaped wire outwards to achieve the set length. During wire processing, the wire first passes through several pairs of straightening rollers 21. The straightening process is completed by the compression and limiting action of these rollers, eliminating the wire's bending deformation. After straightening, the wire is conveyed at a uniform speed under the drive of the feeding rollers 22, and then precisely guided by the feeding tube 23 to the bending module 3. Simultaneously, after the wire is bent, one end of the U-shaped wire can be pushed outwards by the feeding assembly, ensuring the wire's extension length meets the process setting standard. This structural design effectively improves the problems of wire conveying deformation, conveying guide deviation, and insufficient fixed-length output accuracy, ensuring the flatness and length accuracy of the conveyed wire, and providing qualified wire raw materials for subsequent bending processing.

[0021] In existing wire bending processing structures, the wire clamping and positioning stability is insufficient, and the bending drive structure has poor operational stability, easily leading to wire slippage, bending angle deviation, and irregular U-shaped forming. This results in poor product consistency during batch processing. Further, in one embodiment of the present invention, the bending module 3 includes a bending motor 31, a bending connecting table 32, and bending fingers 33. The bending motor 31 is mounted on a frame and is driven by the bending connecting table 32. The bending fingers 33 are located on one side of the bending connecting table 32 and are used to clamp one end of the wire. The wire feed tube 23 serves to orient and position the end of the wire. After the straightened wire extends from the wire feed tube 23, the bending fingers 33 first clamp and fix one end of the wire, limiting displacement during wire processing. Subsequently, the bending motor 31 starts running, driving the bending connecting table 32 to rotate as a whole, simultaneously driving the clamped and fixed end of the wire to rotate, causing the straight wire to bend into a U-shaped wire along a preset trajectory. This structure, through a pre-positioning and then bending process, can effectively improve the problems of slippage, misalignment of forming position, and irregular U-shape during wire bending, thereby enhancing the accuracy of wire bending and the uniformity of batch processing.

[0022] Furthermore, in one embodiment of the present invention, the cutting module 4 includes a first cutting driver 41, a first cutting blade 42, a second cutting driver 43, and a second cutting blade 44. The first cutting driver 41 and the second cutting driver 43 are disposed opposite to each other on the main unit 1. The first cutting driver is driven connected to the first cutting blade 42, and the second cutting driver is driven connected to the second cutting blade 44. The first cutting blade 42 and the second cutting blade 44 are used to cut one end of the U-shaped wire. The cutting module 4 also includes a cutting slide 45 and a cutting slide rail 46. The cutting slide rail 46 is disposed on the main unit 1, and the cutting slide 45 is slidably connected to the cutting slide rail 46. The first cutting driver 41 is driven connected to the cutting slide 45, and the first cutting blade 42 is disposed on the cutting slide 45. After the U-shaped wire is bent and formed and conveyed to a fixed length, the first cutting driver 41 drives the cutting slide 45 to slide precisely along the cutting slide rail 46, moving the first cutting blade 42 to the preset cutting position. At the same time, the second cutting driver 43 drives the second cutting blade 44 to move synchronously in alignment, so that the first cutting blade 42 and the second cutting blade 44 are precisely aligned, and the end of the U-shaped wire is precisely cut. Through the sliding cooperation between the slide rail and the slide, the smoothness and positional accuracy of the first cutting blade 42 can be ensured, improving the problems of blade shaking, large alignment deviation and poor cutting quality of traditional cutting structures, and effectively improving the flatness of the cut and the cutting dimensional accuracy of the U-shaped wire.

[0023] In existing wire stripping processes, insulation debris and waste generated during stripping accumulate directly at the processing station, easily adhering to the wire surface or equipment components, affecting subsequent handling and assembly processes. Furthermore, station cleaning is difficult, resulting in poor work cleanliness. In a further embodiment of the present invention, the stripping module 5 includes a stripping driver 51, a first stripping blade 52, a second stripping blade 53, and a wire insulation suction seat 54. The stripping driver 51 is mounted on the main unit 1. The stripping driver 51 drives the first stripping blade 52 to move relative to each other to strip the insulation from both ends of the U-shaped wire. The wire insulation suction seat 54 is used to remove the stripped wire insulation. After the cut U-shaped wire is transported to the stripping station, the stripping driver 51 is activated, driving the first stripping blade 52 to move relative to the second stripping blade 53, so that the two sets of stripping blades come into contact with the insulation at the wire end. The insulation at the wire end is removed through the shearing and peeling action of the blades. During the stripping process, the detached waste wire insulation is promptly collected and cleaned by the suction action of the wire insulation suction seat 54. This structure can effectively improve the problems of waste wire accumulation, workstation contamination, and waste wire interference with subsequent processing, maintain the cleanliness of the stripping workstation, and ensure the orderly progress of subsequent wire processing procedures.

[0024] In existing wire stripping equipment, there is a lack of targeted damage prevention detection structures. During the stripping process, the stripping blade is prone to excessive contact with the wire core, scratching or cutting the core, damaging the conductive structure of the wire, reducing the performance of the wire, and the damage is difficult to detect in real time, leading to the mass production of defective products. Furthermore, in one embodiment of the present invention, the stripping module 5 also includes a wire core stripping damage prevention detection component. The wire core stripping damage prevention detection component is used to detect whether the blades of the first stripping blade 52 and / or the second stripping blade 53 are in contact with the core of the U-shaped wire, which is the conductor of the U-shaped wire. If the first stripping blade 52 and / or the second stripping blade 53 touch the core, it will reduce the performance of the wire. In this embodiment, the wire core stripping damage prevention detection component is implemented by current detection, that is, it is connected in series with the first stripping blade 52 and the second stripping blade 53 in a wire core stripping damage prevention circuit with a power supply. By detecting the current change in the circuit, it is known whether the first stripping blade 52 and the second stripping blade 53 have contacted the core during the stripping process. During normal insulation stripping, the blade only contacts the insulation material, and the wire core stripping damage prevention circuit is open, with no current flowing through it. However, when the blade feeds excessively and contacts the metallic wire core, the core becomes conductive, creating a closed circuit and causing a current change. The wire core stripping damage prevention detection component captures this current change signal in real time, thus determining that the blade has touched the core. This detection structure can monitor the stripping operation in real time, promptly identifying the risk of core damage, effectively improving the problem of wire core damage from the blade during stripping, and ensuring the integrity and performance of the processed conductor.

[0025] The wire handling module 6 includes a wire handling slide, which is mounted on the frame along the Y-axis; a wire handling frame 61, which is mounted on the wire handling slide and has a wire handling telescopic drive assembly 62. To ensure stable operation and installation of the wire handling telescopic drive assembly 62, the present invention also provides a wire handling frame 61 for supporting and fixing the wire handling telescopic drive assembly 62. The wire handling module 6 also includes a wire limiting fork assembly 63, which includes a first arm 631, a second arm 632, and a wire... The fork clamp finger 633 drives the first arm 631 and the second arm 632 to open and close to limit the U-shaped conductor. The conductor transport module 6 also includes a first wire transport clamping assembly 64 and a second wire transport clamping assembly 65. Both the first wire transport clamping assembly 64 and the second wire transport clamping assembly 65 are driven by the wire transport telescopic drive assembly 62 to move along the x-axis. The first wire transport clamping assembly 64 and the second wire transport clamping assembly 65 are respectively used to clamp the two ends of the U-shaped conductor that are limited by the first arm 631 and the second arm 632. In actual operation, the first arm 631 and the second arm 632 are first driven to open and close by the fork clamp finger 633 to enclose and limit the U-shaped conductor in place, constraining the overall position and shape of the U-shaped conductor. Then, the wire-moving telescopic drive assembly 62 is activated, which drives the first wire-moving clamping assembly 64 and the second wire-moving clamping assembly 65 to move towards each other along the x-axis, accurately aligning and clamping the two ends of the U-shaped conductor. Subsequently, the wire-moving telescopic drive assembly 62 can be used to move the clamped U-shaped conductor to complete the transportation and displacement operation. By adding a front-end limiting structure and an independent telescopic clamping structure, the problems of scattered positions and inaccurate clamping alignment of the U-shaped conductor before transportation can be effectively improved, and the accuracy and standardization of the U-shaped conductor transportation operation can be stably guaranteed.

[0026] In existing wire handling gripper structures, the gripper surfaces are mostly smooth flat structures, resulting in poor contact and fit with U-shaped wires. Radial slippage and positioning misalignment easily occur during U-shaped wire clamping, making it impossible to accurately fix the U-shaped wire's position and affecting the accuracy of subsequent handling operations. Furthermore, in one embodiment of the present invention, the first wire handling clamping assembly 64 includes a first wire handling finger, a first wire clamping head 641, and a second wire clamping head 642. The first wire handling finger drives the first wire clamping head 641 and the second wire clamping head 642 to open and close. A wire groove 643 is provided on the opposing surfaces of the first wire clamping head 641 and the second wire clamping head 642, and the wire groove 643 is used for positioning and clamping the U-shaped wire. When the first wire clamping assembly 64 and the second wire clamping assembly 65 are aligned and clamp the U-shaped wire, the outer wall of the U-shaped wire can fit into the inside of the wire body groove 643. The groove structure of the wire body groove 643 radially limits the U-shaped wire, constrains the sliding offset space of the U-shaped wire, effectively improves the problem of easy slippage and positioning offset during the clamping process of the U-shaped wire, improves the fit and positioning accuracy of the U-shaped wire clamping, and ensures the stability of the U-shaped wire clamping state.

[0027] In the grooved wire clamp structure, the simple groove structure can only achieve basic positioning and cannot guide and constrain the vertical position of the U-shaped wire. When the U-shaped wire is embedded in the groove, it is easy for it to shift vertically or fall out of the groove, resulting in poor guiding and positioning effect. Furthermore, in one embodiment of the present invention, the first wire clamp 641 is provided with an upper wire block 644 and a lower wire block 645. The upper wire block 644 and the lower wire block 645 are located on the upper side and the lower side of the wire groove 643, respectively. The upper wire block 644 and the lower wire block 645, together with the wire groove 643 and the lower wire block 645, form a "V" shaped wire structure. During the U-shaped conductor clamping and alignment process, the U-shaped conductor can smoothly slide into the wire body groove 643 along the inclined surface of the V-shaped conductor structure. The upper conductor block 644 and the lower conductor block 645 can guide and limit the U-shaped conductor from the upper and lower sides. The circular shape structure of the U-shaped conductor enables adaptive alignment, effectively improving the problems of vertical offset and easy disengagement from the clamping area during U-shaped conductor clamping and alignment, and improving the smoothness of U-shaped conductor clamping and guidance and the stability of limit.

[0028] Furthermore, in one embodiment of the present invention, there are two or more upper conductor blocks 644. Two adjacent upper conductor blocks 644 form an upper conductor positioning groove 646. The second clamping head 642 is also provided with upper conductor blocks 644. The upper conductor blocks 644 on the first clamping head 641 and the upper conductor blocks 644 on the second clamping head 642 are staggered, so that the upper conductor blocks 644 on the first clamping head 641 can be inserted into the upper conductor positioning groove 646 on the second clamping head 642. During the process of the first clamping head 641 and the second clamping head 642 closing and clamping the U-shaped conductor, the upper conductor blocks 644 on both sides staggered can be embedded into each other's upper conductor positioning grooves 646, realizing precise alignment and engagement of the upper ends of the two sets of clamping heads, constraining the lateral offset of the two sets of clamping heads, effectively improving the problems of misalignment and uneven clamping gap when the clamping heads are aligned, making the upper side of the U-shaped conductor uniformly stressed, and improving the regularity and stability of the U-shaped conductor clamping.

[0029] Existing wire clamps only have an alignment structure at the upper end, lacking a matching limiting structure at the lower end. During clamping, the lower end of the clamp is prone to shifting, causing the lower limit of the U-shaped conductor to fail, resulting in poor overall clamping balance. Furthermore, in one embodiment of the present invention, there are two or more lower conductor blocks 645. Two adjacent lower conductor blocks 645 form a lower conductor positioning groove 647. The second wire clamp 642 also has lower conductor blocks 645. The lower conductor blocks 645 on the first wire clamp 641 and the lower conductor blocks 645 on the second wire clamp 642 are staggered, allowing the lower conductor blocks 645 on the first wire clamp 641 to insert into the lower conductor positioning groove 647 on the second wire clamp 642. During the clamping operation of the wire head, the lower conductor blocks 645, which are staggered on the lower side, are embedded into the corresponding lower conductor positioning grooves 647, forming a double-layer limiting structure with the upper alignment structure. This simultaneously constrains the alignment accuracy of the upper and lower ends of the wire head, effectively improving the problems of lower end offset and overall force imbalance during the clamping of the U-shaped conductor, and comprehensively enhancing the stability and fit of the U-shaped conductor clamping.

[0030] Traditional wire limiting structures are mostly straight-plate single-position limiting structures, which can only achieve simple obstruction and limiting, and cannot adapt to the structural characteristics of U-shaped conductors. During the limiting process of U-shaped conductors, problems such as outward expansion at both ends and detachment due to lack of support at the bottom are prone to occur, resulting in poor limiting effect. Furthermore, in one embodiment of the present invention, the first arm 631 includes a wire limiting post 6311 and a wire limiting connecting strip 6312, and the wire limiting post 6311 and the wire limiting connecting strip 6312 are connected by a corner. During the opening and closing of the U-shaped conductor by the wire limiting fork assembly 63, the wire limiting post 6311 can vertically block the two side walls of the U-shaped conductor, constraining its outward expansion deformation trend. Simultaneously, the corner between the wire limiting post 6311 and the wire limiting connecting strip 6312 can fit and support the bottom bend of the U-shaped conductor, providing support and limiting from the bottom. This effectively improves the problems of easy outward expansion deformation and easy detachment of the U-shaped conductor during limiting, adapting to the structural shape of the U-shaped conductor to achieve stable limiting. In this embodiment, the U-shaped conductor refers to a conductor that forms a "U" shape after bending.

[0031] Traditional wire clamps and drive components are often integrated structures that are fixedly welded or bolted together. After long-term clamping and wear, the wire clamp cannot be individually disassembled and replaced, requiring complete disassembly and repair, resulting in cumbersome maintenance and high equipment operating costs. Furthermore, in one embodiment of the present invention, the first wire clamp 641 and / or the second wire clamp 642 are detachably connected to the wire-moving telescopic drive component 62. When the first wire clamp 641 or the second wire clamp 642 experiences wear, deformation, or other damage after long-term operation, the worn wire clamp can be individually removed from the wire-moving telescopic drive component 62 for replacement without disassembling the entire wire handling module 6. This effectively improves the cumbersome maintenance and replacement operation of the wire clamp and addresses the high cost of overall replacement, significantly enhancing the convenience of equipment maintenance and reducing equipment operation and maintenance costs.

[0032] The overall operating principle of this device is as follows: The main unit 1 serves as the overall installation and support foundation, providing a stable installation and operating platform for each module. During operation, the wire is first fed out from the wire feeding module 2, straightened by several pairs of wire straightening wheels 21, and then transported to the wire feeding tube 23 via the wire feeding wheel 22. The wire is then guided and transported to the bending module 3 via the wire feeding tube 23. Subsequently, the bending clamping fingers 33 of the bending module 3 clamp the end of the wire, the bending motor 31 drives the bending connecting table 32 to rotate, and the wire feeding module 2 cooperates to release the wire, bending the straight wire into a U-shaped wire. After bending into a U-shaped wire, the U-shaped wire is located between the first arm 631 and the second arm 632 of the limiting fork. At this time, one end of the U-shaped wire is clamped by the bending clamping fingers 33, and the other end is located between the first cutting blade and the second cutting blade of the cutting module. The wire feeding module 2 then restarts, continuing to feed the wire until the U-shaped wire reaches the set length. The cutting driver then actuates, causing the first cutting blade 42 and the second cutting blade 44 to precisely align, completing the cutting of the U-shaped wire end to obtain the required length. The cut U-shaped wire is then transferred by the wire transport module 6. First, the first arm 631 and the second arm 632, driven by the wire fork assembly 63 and the fork gripper 633, retract and limit the U-shaped wire. Then, the first wire clamping assembly 64 and the second wire clamping assembly 65 clamp the wire. At both ends of the wire, the conductor transport slide is driven to complete the Y-axis directional transport, conveying the conductor to the stripping module 5. Then, the wire transfer drive component 62 actuates to extend both ends of the U-shaped conductor between the first stripping blade 52 and the second stripping blade 53. The stripping module 5 drives the first stripping blade 52 and the second stripping blade 53 through the stripping driver 51 to complete the stripping of the insulation at the ends of the conductor. At the same time, the conductor insulation adsorption seat 54 cleans up waste insulation material in real time. During the operation, the conductor core stripping damage prevention detection component monitors the contact status between the blade and the conductor core in real time through current detection. The various structural levels cooperate and operate in a coordinated manner to realize the automated conveying, length setting, bending, cutting, handling, and stripping of double-wire fixed-length conductors throughout the entire process. This effectively improves the problems of fragmented processes, poor precision, low efficiency, and easy product damage in traditional processing methods, ensuring the stability, accuracy, and uniformity of conductor processing.
