Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to a molding apparatus and method for solidifying the shape of automotive wire harnesses. Background Technology

[0002] As the "neural network" of a vehicle's electrical system, the rationality of the spatial layout of automotive wiring harnesses directly affects the assembly efficiency and operational reliability of the entire vehicle. To adapt to the complex installation environment inside the vehicle body, wiring harnesses typically need to be pre-formed into specific three-dimensional bending shapes for rapid alignment and installation during final assembly. Therefore, how to maintain the predetermined shape after bending and prevent springback during wiring harness processing has become a key technical issue of concern in the industry. Existing technologies use heat-shrink tubing or thermoplastic shaping materials wrapped around the parts of the wiring harness that require shaping. Heating causes the shaping material to shrink or soften, and then it is held in a mold to maintain the bending shape and cools and solidifies, thus locking the bending shape of the wiring harness. However, in actual working conditions, there are often open paths for heat transfer between the heating device and the shaping material. Especially when the wiring harness enters or exits the heating zone, heat leakage channels can easily form at the openings of the mold or where the wiring harness passes through, leading to significant heat loss. This temperature loss causes the actual heating temperature of the shaping material to be lower than its optimal molding temperature range, resulting in incomplete curing, insufficient shrinkage of the shaping material, or insufficient softening. Ultimately, the wire harness cannot form a stable bending shape after cooling, resulting in springback, deformation, or even complete failure, which seriously affects the product yield and reliability. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a molding apparatus and method for curing automotive wiring harness shapes, so as to solve the problem of heat leakage during the curing process.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A molding apparatus for curing the shape of automotive wiring harnesses, comprising:

[0006] Fixed base;

[0007] A transmission device, comprising a wire bundling mechanism and a transport mechanism; the wire bundling mechanism is used to bundle multiple wires together; the transport mechanism is provided with a clamping seat and a reciprocating screw, the clamping seat and the reciprocating screw being threadedly connected, the clamping seat being used to clamp the wire bundle and drive the wire bundle to transport along the length direction of the reciprocating screw;

[0008] A curing device includes a bending device and a curing device. The bending device is located at one end of the reciprocating lead screw along the wire harness transport direction and away from the wire harness mechanism. The bending device is provided with a limiting block and a bending block, and the moving direction of the bending block is perpendicular to the wire harness transport direction. The curing device is provided with a temperature isolation mechanism and a heating lamp. The temperature isolation mechanism has a receiving cavity with an inlet and an outlet, which are arranged sequentially along the wire harness transport direction. Each inlet and outlet is provided with at least one heat isolation door, and the fixed end of at least one heat isolation door is located on the top wall of the inlet and the outlet. The heating lamp is located inside the receiving cavity and is used to provide heat for curing the wire harness.

[0009] Furthermore, the inlet is provided with a plurality of thermal isolation doors, which are spaced apart along the width direction of the inlet; the outlet is provided with a plurality of thermal isolation doors, which are spaced apart along the width direction of the outlet.

[0010] Furthermore, the thermal insulation door is made of a flexible transparent material.

[0011] Furthermore, the wire harnessing mechanism includes an annular wire harness and a take-up roller. The annular wire harness has a through hole for the wire harness to pass through, and a take-up rod is slidably connected to the annular wire harness so that the take-up rod can rotate along the circumferential direction of the through hole. The take-up roller is disposed on the clamping seat and the take-up direction is kept at the same horizontal plane as the transport direction of the wire harness. The take-up roller is provided with a conversion rod and multiple limiting plates. The length direction of the conversion rod is perpendicular to the transport direction of the wire harness. The multiple limiting plates are respectively disposed at both ends of the take-up roller and are used to prevent the wire harness from deviating during transport.

[0012] Furthermore, the wire harnessing mechanism is provided with a wire harnessing sleeve, which is fixedly mounted on the fixed base. A movable sleeve is slidably connected to the inner cavity of the wire harnessing sleeve. The movable sleeve is provided with a traction line connected to the take-up roller. The movable sleeve, the annular wire harnessing device, the clamping seat, and the conversion rod are arranged sequentially along the wire harness transportation direction.

[0013] Furthermore, the clamping seat is provided with clamping claws, which are slidably connected to the clamping seat. The clamping claws have an inner arc and are adapted to the outer arc of the wire harness.

[0014] Furthermore, the heating lamp tube includes a first heating lamp tube and a second heating lamp tube, the first heating lamp tube and the second heating lamp tube are respectively disposed on the top wall and the bottom wall of the receiving cavity, a first lamp cover is disposed between the top wall of the receiving cavity and the first heating lamp tube, and a second lamp cover is disposed between the bottom wall of the receiving cavity and the second heating lamp tube.

[0015] Furthermore, a molding apparatus for curing the shape of automotive wiring harnesses also includes multiple conveying roller mechanisms. The multiple conveying roller mechanisms are disposed on the fixed base and spaced apart in the horizontal and vertical directions along the transport direction of the wiring harness. Each conveying roller mechanism is provided with multiple conveying rollers. The conveying roller mechanism is used to smooth out the protrusions on the surface of the cable.

[0016] Furthermore, a molding apparatus for curing the shape of automotive wiring harnesses also includes a drive motor, which is disposed inside the fixed base and is used to drive the apparatus to work.

[0017] Furthermore, a method for solidifying the shape of automotive wiring harnesses includes the following steps: multiple cables are sequentially passed through a conveyor roller mechanism for surface smoothing and straightening, and then fed into the annular cable bundler of the wiring harness mechanism. A winding rod, in conjunction with a take-up roller, circumferentially bundles the multiple cables. A drive motor drives a reciprocating screw to rotate, causing the clamping seat and clamping claws to move linearly along the length of the reciprocating screw. The clamping claws use their inner arc surfaces to clamp and fix the bundled wiring harness, which is then smoothly conveyed along the wiring harness transport direction. When the wiring harness is conveyed to the clamping claw position, the take-up roller winds it up and pulls out the moving sleeve. The take-up roller continues to wind the wiring harness and then transports it to a subsequent platform. A limiting block then moves the wiring harness... The positioning block moves laterally along the direction perpendicular to the wire harness transport, bending the wire harness at a preset angle. The heat isolation doors at the inlet and outlet are opened, and the bent wire harness is sent into the receiving cavity of the temperature isolation mechanism, forming a relatively sealed heat-insulating curing cavity. The first and second heating lamps on the top and bottom walls of the receiving cavity are activated, and together with the first and second lamp covers, they radiate heat evenly. Under the heat insulation effect of the temperature isolation mechanism, the wire harness is heated and cured at a constant temperature. After the wire harness maintains the preset shape after bending, the clamping seat drives the cured wire harness out of the outlet, and the curing operation of the next set of wire harnesses is repeated.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Based on a fixed base and the aforementioned transmission device, the transmission device includes a wire bundling mechanism and a transport mechanism. The wire bundling mechanism is used to bundle multiple wires together. The transport mechanism is equipped with a clamping seat and a reciprocating screw, the clamping seat and the reciprocating screw being threadedly connected. The clamping seat is used to clamp the wire bundle and drive the wire bundle to be transported along the length direction of the reciprocating screw. The fixed base provides a stable mounting foundation for the entire forming device, ensuring that each component maintains a precise relative position during operation and reducing the impact of vibration on the curing accuracy of the wire bundle shape. In the transmission device, the wire bundling mechanism pre-bundles multiple cables into a single wire bundle, avoiding cable scattering or relative slippage during subsequent bending and curing processes, ensuring the consistency of the wire bundle shape. The transport mechanism, using a clamping seat and a reciprocating screw threaded connection, can accurately transport the clamped wire bundle along the length direction of the reciprocating screw, providing a continuous and controllable material flow for subsequent bending and curing processes.

[0020] 2. Based on a morphology curing device, the morphology curing device includes a bending device and a curing device; the bending device is located at the end of the reciprocating lead screw along the wire harness transport direction and away from the wire harness mechanism; the bending device is equipped with a limiting block and a bending block; the moving direction of the bending block is perpendicular to the wire harness transport direction; the bending device is located at the end of the reciprocating lead screw along the wire harness transport direction and away from the wire harness mechanism; the limiting block is used to position and block the wire harness arriving at the bending station, ensuring that the starting position of each bend is consistent. The moving direction of the bending block is perpendicular to the wire harness transport direction, which can apply a lateral force to the wire harness to achieve bending and forming at a preset angle. This vertical bending method avoids pulling or interference to the already transported part of the wire harness during the bending process, thereby improving the accuracy of the bending angle and the repeatability of the wire harness morphology.

[0021] 3. The curing device includes a temperature isolation mechanism and a heating lamp. The temperature isolation mechanism has a receiving cavity with an inlet and an outlet, which are arranged sequentially along the wire harness transport direction. Each inlet and outlet has at least one heat isolation door, with the fixed end of at least one heat isolation door located on the top wall of the inlet and outlet. The heating lamp is located inside the receiving cavity and provides heat for curing the wire harness. The curing device employs a temperature isolation mechanism, with its receiving cavity having an inlet and an outlet arranged sequentially along the transport direction. Each opening has at least one heat isolation door, and the fixed end of the isolation door is located on the top wall. This structure allows the door to hang naturally under gravity, being pushed open when the wire harness passes through and automatically closing afterward, allowing continuous entry and exit of the wire harness while effectively preventing heat leakage from the receiving cavity. The heating lamp is located inside the receiving cavity, providing heat radiation to bring the wire harness to the required curing temperature. The thermal isolation door separates the housing from the external environment, reducing heat convection and heat conduction losses, thereby reducing energy consumption and ensuring that the wire harness is cured in a constant temperature environment, improving curing quality and efficiency.

[0027] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See Figures 1-3 A preferred embodiment of the present invention provides a molding apparatus for curing the shape of automotive wiring harnesses, comprising: a fixed base 1, a transmission device 2, and a shape curing device 3.

[0030] The transmission device 2 includes a wire bundling mechanism 201 and a transport mechanism 203; the wire bundling mechanism 201 is used to bundle multiple wires together; the transport mechanism 203 is provided with a clamping seat 2031 and a reciprocating screw 2032, the clamping seat 2031 and the reciprocating screw 2032 are threadedly connected, the clamping seat 2031 is used to clamp the wire bundle and drive the wire bundle to transport along the length direction of the reciprocating screw 2032;

[0031] The curing device 3 includes a bending device 4 and a curing device. The bending device 4 is located at one end of the reciprocating screw 2032 along the wire harness transport direction and away from the wire harness mechanism 201. The bending device 4 is provided with a limiting block 401 and a bending block 402. The moving direction of the bending block 402 is perpendicular to the wire harness transport direction. The curing device 5 is provided with a temperature isolation mechanism 501 and a heating lamp 502. The temperature isolation mechanism 501 has a receiving cavity 5011. The receiving cavity 5011 is provided with an inlet 5012 and an outlet 5013. The inlet 5012 and the outlet 5013 are arranged sequentially along the wire harness transport direction. Both the inlet 5012 and the outlet 5013 are provided with at least one heat isolation door 6. The fixed end of at least one heat isolation door 6 is located on the top wall of the inlet 5012 and the outlet 5013. The heating lamp 502 is located inside the receiving cavity 5011 and is used to provide heat for the wire harness curing.

[0032] During operation, the fixed base 1 supports all components; in the transmission device 2, the cable bundling mechanism 201 bundles multiple loose cables into a single cable bundle; the clamping seat 2031 of the transport mechanism 203 clamps the cable bundle and, driven by the reciprocating screw 2032, moves it stepwise along its length. When the cable bundle reaches the bending device 4, the limiting block 401 positions and blocks it, and the bending block 402 moves laterally perpendicular to the transport direction, bending the cable bundle into a preset angle. The bent cable bundle continues to be transported to the inlet 5012 of the receiving cavity 5011 of the curing device 5, and the heat isolation door 6 automatically closes after being pushed open by the cable bundle; after the cable bundle enters the receiving cavity 5011, the heating lamp 502 radiates heat, and under the heat insulation effect of the temperature isolation mechanism 501, the cable bundle is heated and cured at a constant temperature, maintaining the bent shape. After curing is complete, the clamp 2031 drives the wire harness to be sent out from the outlet 5013, and the heat isolation door 6 automatically closes again, completing one work cycle.

[0033] Preferably, the inlet 5012 is provided with multiple heat-insulating doors 6, which are spaced apart along the width direction of the inlet 5012; the outlet 5013 is provided with multiple heat-insulating doors 6, which are spaced apart along the width direction of the outlet 5013. The multiple heat-insulating doors 6 spaced apart along the width direction at the inlet 5012 and outlet 5013 respectively form multiple heat insulation barriers, reducing heat leakage from the cavity 5011 through the door gaps. The multiple doors can open and close independently; when the wire harness passes through, only the part of the door in contact with the wire harness is pushed open, while the remaining doors remain closed. This maximizes the temperature uniformity and stability within the cavity 5011 during continuous transport, improving the curing effect and reducing energy consumption.

[0034] Preferably, the heat insulation door 6 is made of a flexible transparent material. It has good flexibility and can be easily pushed open when the wire harness passes through without scratching or damaging the surface of the wire harness. On the other hand, the transparency allows the operator to directly observe the curing state of the wire harness inside the receiving cavity 5011 and the working status of the heating lamp 502 from the outside, which is convenient for real-time monitoring and troubleshooting without opening the door, thus avoiding heat loss.

[0035] Preferably, the wire harnessing mechanism 201 includes an annular wire harness 2011 and a take-up roller 202. The annular wire harness 2011 has a through hole 2012 for the wire harness to pass through. The annular wire harness 2011 is slidably connected to a winding rod 7 so that the winding rod 7 can rotate along the circumferential direction of the through hole 2012. The take-up roller 202 is located on the clamping seat 2031 and its winding direction is on the same horizontal plane as the transport direction of the wire harness. The take-up roller 202 has a conversion rod 2021 and multiple limiting plates 2022. The length direction of the conversion rod 2021 is perpendicular to the transport direction of the wire harness. The multiple limiting plates 2022 are respectively located at both ends of the take-up roller 202 and are used to prevent the wire harness from shifting during transport. The through hole 2012 of the annular wire harness 2011 allows the wire harness to pass through. The rotation of the winding rod 7 along the circumferential direction of the through hole 2012 can wrap the binding material (such as heat shrink tape) around the outside of the wire harness to achieve uniform binding of multiple cables. The take-up roller 202 is mounted on the clamping seat 2031 with its take-up direction and transport direction on the same horizontal plane. This allows for simultaneous tightening of the binding material during wire harness transport, preventing tangling and loosening. The conversion rod 2021, with its length perpendicular to the transport direction, can convert the direction of the binding material from rotation to transport, achieving a smooth transition. The limiting plates 2022 at both ends of the take-up roller 202 effectively prevent lateral deviation of the wire harness during transport, ensuring that the wire harness always moves along the preset path, improving transport stability and bending positioning accuracy.

[0036] Preferably, the cable bundling mechanism 201 includes a cable bundling sleeve 8, which is fixedly mounted on the fixed base 1. A movable sleeve 9 is slidably connected to the inner cavity of the cable bundling sleeve 8. The movable sleeve 9 is provided with a traction line 10 connected to the take-up roller 202. The movable sleeve 9, the annular cable bundler 2011, the clamping seat 2031, and the conversion rod 2021 are arranged sequentially along the cable harness transport direction. The cable bundling sleeve 8 and the movable sleeve 9 constitute a retractable guide structure. The movable sleeve 9 is connected to the take-up roller 202 via the traction line 10. When the take-up roller 202 rotates and rewinds, the traction line 10 pulls the movable sleeve 9 to slide along the inner cavity of the cable bundling sleeve 8. The movable sleeve 9, the annular cable bundler 2011, the clamping seat 2031, and the conversion rod 2021 are arranged sequentially along the cable harness transport direction, forming a continuous working chain from cable introduction, bundling, clamping to direction conversion, avoiding tangling or jamming of the cable harness during transmission.

[0037] Preferably, the clamping base 2031 is provided with clamping claws 11, which are slidably connected to the clamping base 2031. The clamping claws 11 have an inner arc 12 that adapts to the outer arc of the wire harness. The slidable connection of the clamping claws 11 to the clamping base 2031 allows for adjustment of the clamping opening according to the wire harness diameter, accommodating wire harnesses of different specifications. The inner arc 12 of the clamping claws 11 matches the outer arc of the wire harness, increasing the clamping contact area. This not only firmly clamps the wire harness to prevent slippage during transportation and bending, but also avoids damage to the wire harness surface or deformation of the wire core due to excessive local pressure, protecting the integrity and electrical performance of the wire harness.

[0038] Preferably, the heating lamp 502 includes a first heating lamp 5021 and a second heating lamp 5022. The first heating lamp 5021 and the second heating lamp 5022 are respectively disposed on the top wall and bottom wall of the receiving cavity 5011. A first lamp cover 5023 is disposed between the top wall of the receiving cavity 5011 and the first heating lamp 5021, and a second lamp cover 5024 is disposed between the bottom wall of the receiving cavity 5011 and the second heating lamp 5022. The first heating lamp 5021 and the second heating lamp 5022 are respectively disposed on the top wall and bottom wall of the receiving cavity 5011, which realizes simultaneous and uniform heating of the upper and lower surfaces of the wire harness, avoiding the problem of uneven curing caused by unilateral heating. The first lamp cover 5023 and the second lamp cover 5024 are respectively disposed between the lamp and the cavity wall, which on the one hand reflects and focuses the heat towards the direction of the wire harness, improving the heat radiation efficiency; on the other hand, protects the cavity wall material from aging or damage caused by direct heat radiation from the lamp, and facilitates the installation and replacement of the lamp.

[0039] Preferably, a molding apparatus for curing the shape of automotive wire harnesses further includes multiple conveyor roller mechanisms 13. These mechanisms are disposed on a fixed base 1 and spaced apart horizontally and vertically along the transport direction of the wire harness. Each conveyor roller mechanism 13 is equipped with multiple conveyor rollers 14. The conveyor roller mechanisms 13 are used to smooth out protrusions on the cable surface. The multiple conveyor roller mechanisms 13, spaced apart horizontally and vertically along the transport direction, and each equipped with multiple conveyor rollers 14, can apply rolling pressure to the cable surface from multiple angles and directions, effectively smoothing out localized protrusions, burrs, or entanglements generated during production or handling, resulting in a smooth and regular cable surface. This not only improves the fit and uniformity of the subsequent wire harnessing mechanism 201 but also avoids stress concentration or shape defects caused by protrusions during bending and curing, thus improving the final quality of the wire harness.

[0040] Preferably, a molding device for solidifying automotive wiring harness shapes further includes a drive motor 15, which is disposed inside the fixed base 1 and drives the device. The drive motor 15's placement inside the fixed base 1 fully utilizes the internal space, resulting in a compact overall structure and reduced footprint. Simultaneously, the built-in design provides some protection for the motor, preventing external dust and wiring harness debris from entering and extending its lifespan. The drive motor 15 centrally powers moving components such as the reciprocating lead screw 2032, the take-up roller 202, and the winding rod 7, achieving synchronous and coordinated control of various actions, simplifying the transmission system, and improving operational reliability.

[0041] Preferably, a method for solidifying the shape of automotive wiring harnesses includes the following steps: multiple cables are sequentially passed through a conveyor roller mechanism 13 for surface smoothing and straightening, and then fed into the annular cable bundler 2011 of the cable bundling mechanism 201. The multiple cables are circumferentially bundled by a winding rod 7 in conjunction with a take-up roller 202; a drive motor 15 drives a reciprocating screw 2032 to rotate, causing the clamping seat 2031 and clamping claw 11 to move linearly along the length of the reciprocating screw 2032. The clamping claw 11 uses its inner arc 12 surface to clamp and fix the bundled wire harness, which is then smoothly conveyed along the wire harness transport direction; when the wire harness is conveyed to the position of the clamping claw 11, the take-up roller 202 winds it up and pulls out the moving sleeve 9. The take-up roller 202 continues to wind up and then transports the wire harness to a subsequent platform; a limit block 401 positions the wire harness. The bending block 402 moves laterally along the direction perpendicular to the wire harness transport to bend and shape the wire harness at a preset angle. The heat isolation door 6 at the inlet 5012 and outlet 5013 is opened, and the bent wire harness is sent into the receiving cavity 5011 of the temperature isolation mechanism 501 to form a relatively sealed heat-insulating curing cavity. The first heating lamp 5021 and the second heating lamp 5022 on the top and bottom walls of the receiving cavity 5011 are activated, and the first lamp cover 5023 and the second lamp cover 5024 radiate heat evenly. Under the heat insulation effect of the temperature isolation mechanism 501, the wire harness is heated and cured at a constant temperature. After the wire harness maintains the preset shape after bending, the clamping seat 2031 drives the cured wire harness out from the outlet 5013, and the curing operation of the next set of wire harnesses is repeated.

A molding apparatus for curing the shape of automotive wiring harnesses according to claim 1, characterized in that, A molding apparatus for solidifying the shape of automotive wiring harnesses further includes a drive motor (15), which is disposed inside the fixed base (1) and is used to drive the device to work.

10. A method for curing the shape of automotive wiring harnesses, comprising a molding apparatus for curing the shape of automotive wiring harnesses as described in any one of claims 1-9, characterized in that, The process includes the following steps: multiple cables are passed sequentially through the conveyor roller mechanism (13) to smooth and level their surfaces, and then fed into the annular cable bundler (2011) of the cable bundling mechanism (201). The multiple cables are then circumferentially bundled by the winding rod (7) in conjunction with the take-up roller (202); the drive motor (15) drives the reciprocating screw (2032) to rotate, causing the clamping seat (2031) and clamping claw (11) to move linearly along the length of the reciprocating screw (2032). The clamping claw (11) uses its inner arc (12) surface to clamp and fix the bundled cable bundle, and then smoothly transports it along the cable bundle transport direction; when the cable bundle is transported to the position of the clamping claw (11), the take-up roller (202) winds it up and pulls out the moving sleeve (9). The take-up roller (202) continues to wind up and then transports the cable bundle to the subsequent platform; the limit block (401) positions and blocks the cable bundle, and the bending block ( 402) Move laterally along the direction perpendicular to the wire harness transport and bend the wire harness at a preset angle; open the heat isolation door (6) at the inlet (5012) and outlet (5013) and send the bent wire harness into the receiving cavity (5011) of the temperature isolation mechanism (501) to form a relatively sealed heat insulation curing cavity; start the first heating lamp (5021) and the second heating lamp (5022) on the top and bottom walls of the receiving cavity (5011), and work with the first lamp cover (5023) and the second lamp cover (5024) to radiate heat evenly. Under the heat insulation and heat preservation effect of the temperature isolation mechanism (501), the wire harness is heated and cured at a constant temperature. After the wire harness is kept in the preset shape after bending, it is driven by the clamp (2031) to send the cured wire harness out from the outlet (5013) and repeat the curing operation of the next set of wire harnesses.
