Description

Technical Field

[0001] This utility model relates to the technical field of wire harness production and preparation, and in particular to a batch cutting device for wire harness production. Background Technology

[0002] Wire harnesses are widely used in many fields such as electronics, automobiles, and engineering machinery. They are the core connectors for signal transmission and power supply between components. In their production process, the cutting process is a key link for subsequent assembly and compatibility.

[0003] In the existing technology, the cutting equipment for single wire harnesses is already very mature and can fully meet the precision requirements for cutting a single wire harness. For example, Chinese invention patent with announcement number "CN119794219A" discloses a new energy vehicle wire harness cutting device, including a base, mounting base, wire reel, clamping assembly, guiding assembly, cutting assembly, clamping assembly, U-shaped support base, fixing rod, lower clamping wheel, first threaded rod, concave support rod, upper clamping wheel, and handwheel. The mounting base is symmetrically arranged on one side of the upper part of the base, and the wire reel is rotatably arranged between the mounting bases. The clamping assembly is arranged on one side of the wire reel, the guiding assembly is arranged on one side of the clamping assembly, the cutting assembly is arranged on one side of the guiding assembly, and the clamping assembly is arranged on one side of the cutting assembly. The clamping assembly includes a U-shaped support base, fixing rod, lower clamping wheel, first threaded rod, concave support rod, upper clamping wheel, and handwheel. The U-shaped support base is located on the base. However, such equipment can only process one wire harness at a time, and its production efficiency is no longer sufficient to meet the current demand for large-scale and high-efficiency wire harness production. Therefore, to improve production efficiency, a batch processing device that can simultaneously cut multiple wire harnesses is needed.

[0004] However, batch cutting equipment for wire harnesses is not simply a stacking or parallel arrangement of existing single-wire cutting equipment. For example, Chinese utility model patent CN223043538U discloses a cutting device for automotive wire harness production, including an operating table. One end of the operating table is equipped with a cutting assembly, and the other end is equipped with a tensioning mechanism. Several limiting structures for wire harnesses to pass through are arranged on the operating table between the cutting assembly and the tensioning mechanism. The tensioning mechanism includes symmetrically arranged vertical plates, with a first auxiliary roller and a second auxiliary roller arranged between the two vertical plates. A drive roller is arranged between the first auxiliary roller and the second auxiliary roller, and adjusting components are respectively arranged at both ends of the drive roller, with the adjusting components connected to the corresponding vertical plates. This design lacks a systematic design for the synchronous conveying and precise guidance of multiple wire harnesses, which can easily lead to lateral deviation of each wire harness during the conveying process. This results in deviations in cutting time and conveying length, making it impossible to achieve uniform cutting of multiple wire harnesses. Ultimately, this leads to poor consistency in the output length of the batch-cut wire harnesses, affecting the precise connection of subsequent stripping and crimping processes, and even causing product assembly accidents.

[0005] Therefore, this application provides a reasonable wire harness conveying synchronization mechanism and a cutting action coordination structure to ensure that the wire harness output length after batch cutting is highly uniform, thereby improving production efficiency while ensuring product quality, so as to meet the core technical requirements of mass production for batch equipment. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a batch cutting device for wire harness production, which has a reasonable wire harness conveying synchronization mechanism and a cutting action coordination structure to ensure that the output length of the wire harness after batch cutting is highly uniform, thereby improving production efficiency while ensuring product quality.

[0007] To achieve the above and other related objectives, this utility model provides the following technical solution: A batch cutting device for wire harness production includes a feeding assembly for conveying the wire harness downstream; The conveying assembly located downstream of the unloading assembly along the wire harness conveying direction includes a conveying plate with several limiting channels for the wire harness to pass through, several pairs of rollers arranged on the upper and lower sides of the wire harness to convey the wire harness of equal length downstream by clamping force, and a drive structure that drives the rollers to rotate synchronously in opposite directions; the limiting channels are parallel to each other and evenly distributed in the conveying plate. A cutting assembly located downstream of the conveying assembly and perpendicular to the conveying plate to cut the wire harness.

[0008] To achieve the above technical solution, a fixed channel is provided for the conveying of the wire harness through the design of the limiting channel. At the same time, the synchronous reverse rotation with the rollers ensures the uniformity of the conveying length of the wire harness and guarantees the cutting accuracy of the wire harness.

[0009] Furthermore, the conveying assembly also includes several clamping structures located at the end of the conveying plate along the wire harness conveying direction; the clamping structures are configured one-to-one with the limiting channels to clamp the wire harness to ensure the positioning accuracy of the wire harness before cutting.

[0010] To achieve the above technical solution, the clamping structure is designed to clamp the wire harness before cutting, ensuring accurate positioning of the wire harness and preventing displacement of the wire harness during cutting.

[0011] Furthermore, the clamping structure includes a pair of clamping blocks facing the cutting assembly, and the clamping blocks are provided with strip grooves opened along the wire harness conveying direction; the strip grooves together form a receiving groove communicating with the limiting channel, the receiving groove is used to support the wire harness and cooperate with the cutting assembly to apply shear stress to the wire harness.

[0012] To achieve the above technical solution, a strip groove is designed on the clamping block to provide a receiving groove that can carry the wire harness when the clamping block is closed. This receiving groove can cooperate with the cutting component to apply shear stress to the wire harness.

[0013] Furthermore, the drive structure includes a drive motor located on one side of the conveyor plate perpendicular to the wire harness conveying direction, a drive roller located below the conveyor plate and connected to the output end of the drive motor, and a driven roller located above the conveyor plate opposite to the drive roller and rotates synchronously at the same speed through gear meshing.

[0014] To achieve the above technical solution, the synchronous transfer and rotation between the driving roller and the driven roller is realized through gear meshing, thereby providing rotational driving force for the upper and lower rollers set on the driven roller and the driving roller.

[0015] Furthermore, the rollers include lower rollers spaced apart from each other and sleeved on the drive roller, and upper rollers that are connected to the driven rollers via a gear set for transmission. The upper rollers and lower rollers are arranged opposite each other and rotate synchronously in opposite directions, and the gap between them is configured as a limiting channel.

[0016] To achieve the above technical solution, the gap between the upper and lower rollers is configured as an extension of the limiting channel, ensuring that the wire harness remains in a straight line during transport and further guaranteeing the accuracy of wire harness transport.

[0017] Furthermore, the conveyor plate is provided with a clearance groove that runs through the wire harness conveying direction, and the upper roller extends at least partially into the clearance groove to apply a clamping force to the wire harness.

[0018] To achieve the above technical solution, the design of the clearance groove provides space for the pressing fit between the upper roller and the lower roller, ensuring that the upper roller and the lower roller can fully contact the wire harness and apply a stable pressing force.

[0019] Furthermore, it also includes hydraulic rods vertically installed above the conveyor plate, with each hydraulic rod corresponding to one of the upper rollers. The output end of the hydraulic rod is connected to the upper roller to drive the upper roller to move in the vertical direction, so that the upper roller separates from or fits with the lower roller.

[0020] To achieve the above technical solution, the hydraulic rod design allows the upper and lower rollers to move away from or be close to each other. Without affecting the contact conveying of the wire harness by the upper and lower rollers, the upper roller can move away from the lower roller, making it convenient for technicians to insert the wire harness into the limiting channel.

[0021] Furthermore, the cutting assembly includes a support plate installed perpendicular to the conveyor plate, and several cutting structures slidably connected to the support plate and facing the conveyor plate, with the cutting structures and clamping structures corresponding one-to-one.

[0022] To achieve the above technical solution, the cutting structure is designed and works in coordination with the clamping structure to apply shear stress to the wire harness, thereby cutting and severing the wire harness.

[0023] Furthermore, the cutting structure includes a cutting blade that abuts against the top of the clamping block and a limiting block disposed on the side of the cutting blade near the conveying assembly; the limiting block extends at least partially into the receiving groove along a direction perpendicular to the conveying plate to limit the wire harness.

[0024] To achieve the above technical solution, the limiting block extends vertically into the receiving groove to axially position the wire harness, preventing the wire harness from axially shifting due to the force of the cutting blade during cutting, and further improving the cutting accuracy of the wire harness.

[0025] Furthermore, it also includes a worktable for carrying the conveyor plate, the worktable being equipped with guide rails arranged along the wire harness conveying direction, and the conveyor plate being slidably connected to the worktable via the guide rails.

[0026] To achieve the above technical solution, the guide rails on the worktable allow the conveyor plate to slide along the guide rails and be connected to the worktable. The conveyor plate can be close to the unloading component, making it convenient for technicians to thread the wire harness into the limiting channel.

[0027] As described above, the batch cutting device for wire harness production of this utility model has the following beneficial effects: 1. In this application, the design of the limiting channel provides a fixed channel for the conveying of the wire harness. At the same time, the synchronous reverse rotation with the rollers achieves uniformity in the conveying length of the wire harness and ensures the cutting accuracy of the wire harness.

[0028] 2. In this application, the design of the limiting block can axially position the wire harness when cutting it, preventing the wire harness from moving axially due to the force of the cutting blade during cutting, and further improving the cutting accuracy of the wire harness.

[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0039] Please see Figure 1-8It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0040] Please see Figures 1 to 8 This utility model provides a batch cutting device for wire harness production, including a feeding assembly 1 for conveying wire harnesses downstream, a conveying assembly 2 located downstream of the feeding assembly 1 along the wire harness conveying direction, and a cutting assembly 3 located downstream of the conveying assembly 2 and perpendicular to the conveying assembly 2 for cutting the wire harnesses. The feeding assembly 1 is located at the uppermost part of the device and is a multi-station wire feeding frame structure, including several rotatable feeding rollers 11 mounted thereon and guide wheels 12 for guiding each wire harness.

[0041] Specifically, the conveying assembly 2 includes a conveying plate 21 with several limiting channels 211 for wire harnesses to pass through, several pairs of rollers 22 arranged on the upper and lower sides of the wire harnesses to convey wire harnesses of equal length downstream by clamping force, and a drive structure 23 that drives the rollers 22 to rotate synchronously in opposite directions.

[0042] The limiting channels 211 are parallel to each other and evenly distributed within the conveyor plate 21, with the wire harness conveying direction extending through the conveyor plate 21. The inner diameter of each limiting channel 211 is 0.2mm larger than the outer diameter of the wire harness to be processed, controlling the gap between the wire harness and the limiting channel 211 to be between 0.1-0.3mm. This ensures that the wire harness remains straight within the limiting channel 211 and can be conveyed smoothly, while also preventing lateral deviation during conveying. Furthermore, the number of wires fed by the feed roller 11 is consistent with the number of limiting channels 211. The inner surface of the limiting channel 211 is polished to reduce friction between the inner surface and the wire harness, further ensuring smooth conveying of the wire harness within it. It should be noted that the production of a single model of wire harness is characterized by large batch size and long production cycle. During this production cycle, the inner diameter of the limiting channel 211 does not need to change. Therefore, the limiting channel 211 adopts a through hole design that passes through the conveyor plate 21, which can ensure the overall accuracy and structural strength of the limiting channel 211. When the specifications of the wire harness change, the inner diameter of the limiting channel 211 can be changed by replacing different conveyor plates 21 to adapt to the production needs of wire harnesses of different specifications.

[0043] In one specific embodiment, the rollers 22 are arranged in a one-to-one correspondence and are both made of nitrile rubber to ensure that they will not damage the wire harness while maintaining a certain degree of rigidity. The rollers 22 apply a floating clamping force to the wire harness in pairs. Their clamping surfaces are provided with 0.5mm deep anti-slip textures to enhance the friction between them and the surface of the wire harness and prevent slippage during transportation.

[0044] In this application, the design of the limiting channel 211 provides a fixed channel for the conveying of the wire harness. At the same time, the synchronous reverse rotation with the roller 22 achieves uniformity of the wire harness conveying length and ensures the cutting accuracy of the wire harness.

[0045] Please continue reading. Figure 6 and Figure 7 The conveying assembly 2 also includes several clamping structures 24 located at the ends of the conveying plate 21 along the wire harness conveying direction.

[0046] Specifically, the clamping structure 24 is evenly arranged along the end of the conveying plate 21 near the cutting component 3, perpendicular to the wire harness conveying direction, and is set one-to-one with the limiting channel 211. It is used to clamp the wire harness before cutting, ensure the accurate positioning of the wire harness, and prevent the wire harness from shifting during cutting.

[0047] The clamping structure 24 includes a pair of clamping blocks 241 facing the cutting assembly 3 and a cylinder 242 located on the side of the clamping blocks 241 away from the cutting assembly 3 to drive the clamping blocks 241 to close and open. The clamping blocks 241 are arranged opposite each other and are made of hard metal alloy, which has high hardness and wear resistance. The opposite surfaces of the pair of clamping blocks 241 are provided with strip grooves 2411 extending along the wire harness conveying direction. When the two clamping blocks 241 approach each other and close, the two strip grooves 2411 surround and form a receiving groove 2412 connected to the limiting channel 211. The center line of the receiving groove 2412 is collinear with the center line of the limiting channel 211. The receiving groove 2412 is used to receive and support the wire harness and cooperate with the cutting assembly 3 to apply shear stress to the wire harness.

[0048] Please continue reading. Figure 2 The drive structure 23 includes a drive motor 231 disposed on one side of the conveyor plate 21 perpendicular to the wire harness conveying direction, a drive roller 232 disposed below the conveyor plate 21 and connected to the output end of the drive motor 231, and a driven roller 233 disposed above the conveyor plate 21 opposite to the drive roller 232 and rotating synchronously with it. The drive motor 231 includes a servo motor.

[0049] Both the drive roller 232 and the driven roller 233 are made of stainless steel. One end of the drive roller 232 is provided with a drive gear 2321, and the corresponding end of the driven roller 233 is provided with a driven gear 2331. An idler gear 234 that changes the rotation direction of the driven gear is also meshed between the drive gear 2321 and the driven gear 2331, so as to realize the synchronous rotation between the drive roller 232 and the driven roller 233.

[0050] Furthermore, the roller 22 includes a lower roller 221 spaced apart from each other and sleeved on the drive roller 232, and an upper roller 222 that is connected to the driven roller 233 by a gear set for transmission. The gear set enables synchronous reverse rotation between the upper roller 222 and the lower roller 221.

[0051] In one specific embodiment, the spacing between the pairs of rollers 22 is consistent with the spacing between the limiting channels 211, ensuring that each wire harness can accurately correspond to a pair of upper rollers 222 and lower rollers 221. Furthermore, the gap between the upper rollers 222 and lower rollers 221 forms an extension of the limiting channel 211, ensuring that the wire harness remains in a straight line during transport, further guaranteeing the accuracy of wire harness transport.

[0052] In addition, the conveyor plate 21 is provided with clearance grooves 212 corresponding one-to-one with the limiting channels 211, and the width of the clearance grooves 212 is greater than the width of the upper roller 222 and the lower roller 221. The clearance grooves 212 extend along the wire harness conveying direction and penetrate the conveyor plate 21, providing space for the pressing fit between the upper roller 222 and the lower roller 221, ensuring that the upper roller 222 and the lower roller 221 can fully contact the wire harness and apply a stable pressing force.

[0053] Please continue reading. Figure 4 This application also includes a hydraulic rod 4 vertically mounted above the conveyor plate 21.

[0054] Specifically, the hydraulic rod 4 is configured to correspond one-to-one with the upper roller 222. It includes a hydraulic cylinder 41 that provides tension or thrust to the upper roller 222 and a piston rod 42 that is connected to the shaft of the upper roller 222 through a floating joint. It is used to drive the upper roller 222 to move in the vertical direction, so as to realize the separation or contact between the upper roller 222 and the lower roller 221.

[0055] In one specific embodiment, when the wire harness needs to be placed, the piston rod 42 retracts, driving the upper roller 222 to move upward, so that the upper and lower rollers 22 separate, making it easier for the wire harness to pass through the limiting channel 211; after the wire harness is passed through, the piston rod 42 extends, the upper roller 222 moves downward and fits against the lower roller 221, clamping the wire harness with a preset clamping force to ensure that there is no slippage during delivery.

[0056] Please continue reading. Figure 3 and Figure 8 The cutting structure 32 includes a support plate 31 perpendicular to the conveyor plate 21, a cutting structure 32 slidably connected to the support plate 31 and corresponding to the clamping structure 24, and a first drive unit 33 for driving the cutting structure 32 to reciprocate. The first drive unit 33 includes a servo motor.

[0057] Specifically, the support plate 31 has a groove 311 that corresponds one-to-one with the cutting structure 32, and the groove 311 extends along the height direction of the support plate 31. The cutting structure 32 is positioned facing the conveyor plate 21 and is slidably connected to the support plate 31 through the groove 311. Under the drive of the first drive unit 33, it moves closer to or away from the conveyor plate 21 along the opening direction of the groove 311.

[0058] The cutting structure 32 includes a connecting plate 323 slidably connected in the slide groove 311, a cutting blade 321 installed at the end of the connecting plate 323 facing the clamping block 241 and abutting against the top of the clamping block 241, and a limiting block 322 disposed on the side of the cutting blade 321 near the clamping block 241. The limiting block 322 and the connecting plate 323 are elastically connected and connected by a return spring. The limiting block 322 extends at least partially into the receiving groove 2412 in the vertical direction and abuts against the wiring harness.

[0059] In one specific embodiment, the length of the limiting block 322 is greater than the length of the cutting blade 321 in the vertical direction, that is, the limiting block 322 protrudes beyond the cutting blade 321. When the cutting structure 32 cuts the wire harness, the first driving unit 33 drives the cutting structure 32 to move downward. The limiting block 322 first enters the receiving groove 2412 in the vertical direction to axially position the wire harness, preventing the wire harness from axially shifting due to the force of the cutting blade 321 during cutting, and further improving the cutting accuracy of the wire harness.

[0060] Please continue reading. Figure 1 It also includes a horizontally arranged workbench 5 for supporting the conveyor plate 21. The workbench 5 includes a collection box 51 located below the cutting assembly 3 and a pair of guide rails 52 extending along the wire harness conveying direction. The conveyor plate 21 has a guide groove 213 adapted to the guide rail 52 on the side facing the workbench 5. Through the sliding fit between the guide groove 213 and the guide rail 52, the conveyor plate 21 can move back and forth on the workbench 5 along the guide rail 52.

[0061] In one specific embodiment, a limiting plate 521 is provided at one end of the guide rail 52 near the cutting assembly 3 to position the conveying plate 21. Before the wire harness needs to be cut, the conveying plate 21 is slid along the guide rail 52 until it abuts against the limiting plate 521. At the same time, the top of the clamping block 241 can abut against the cutting blade 321. Then, by inserting the pin through the guide groove 213 and the guide rail 52, the position of the conveying plate 21 is fixed to prevent displacement during the wire harness cutting process and reduce the cutting accuracy of the wire harness.

[0062] In some other embodiments, a second drive unit 25 is provided below the conveyor plate 21. The output end of the second drive unit 25 is connected to the bottom of the conveyor plate 21, so that the second drive unit 52 can drive the conveyor plate 21 to reciprocate along the length of the guide rail 52. The second drive unit includes a servo motor.

[0063] It should be noted that this application includes a PLC control unit that is electrically connected to the drive motor 231 and the first drive unit 33. The control unit includes a built-in programmable controller and an interactive screen, which allows technicians to set the rotation angle of the drive motor 231 and the moving distance of the output end of the first drive unit 33 to the PLC control unit in order to control the length of wire harness delivery and cutting, as well as the falling distance of the cutting structure 32.

[0064] The implementation principle of the batch cutting device for wire harness production in this utility model is as follows: Before cutting, the technician needs to thread the wire harness into the limiting channel 211 in sequence. Therefore, the conveyor plate 21 needs to be away from the cutting component 3 and close to the unloading component 1. Then, the technician passes the wire harness on the unloading roller 11 around the guide wheel 12 and enters it from one side of the limiting channel 211 in the conveyor plate 21. After passing through the gap between the upper and lower rollers 22, it exits from the side close to the cutting component 3. The end of the wire harness is led out from the receiving groove 2412 and clamped by the clamping block 241 to fix the wire harness. Then, the conveyor plate 21 slides along the guide rail 52 and resets. The piston rod 42 extends, and the upper roller 222 moves down and at least partially extends into the clearance groove 212 to cooperate with the lower roller 221 to clamp the wire harness. Then, the drive motor 231 is started. The drive motor 231 drives the drive roller 232 to rotate. At the same time, the driven roller 233 is driven to rotate synchronously through gear meshing. The upper roller 222 is driven to rotate by the gear set, so that the upper roller 222 and the lower roller 221 rotate synchronously in opposite directions. Under the action of the friction of the upper and lower rollers 22, the wire harness in the limiting channel 211 is conveyed toward the cutting assembly 3. When the wire harness reaches the preset length, the PLC control unit sends an electrical signal to the drive motor 231 to stop working. Then, the PLC control unit sends an electrical signal to the first drive unit 22. Under the drive of the first drive unit 33, the cutting structure 32 moves toward the conveying plate 21. The limiting block 322 first enters the receiving groove 2412 to axially position the wire harness. The elastic deformation of the return spring between the cutting structure 322 and the connecting plate 323 keeps the wire harness in the receiving groove 2412. The return spring is compressed as the cutting blade 321 falls until the cutting blade 321 cuts the wire harness. Then, the cut wire harness falls into the collection box 51, the cutting structure 32 resets, the drive motor 231 starts, and the wire harness is conveyed downstream again. This cycle continues.

[0065] It should be noted that during the first wire harness delivery, since the wire harness is inserted and led out by technicians, the ends of the wire harness are uneven. Therefore, it is necessary to cut the wire harness for the first time and align the top ends of the wire harness.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
