Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness processing technology, specifically to an integrated feeding and sorting device for automotive wiring harness processing. Background Technology

[0002] Automotive wiring harnesses are made of a new type of precious metal material used in electric vehicles. They are used in the connection circuits of electric vehicles, electric motors, electric drives, and batteries. They belong to the category of electric vehicle device and accessory manufacturing. The contact terminals made of copper are crimped with wires and cables, and then an insulation material or an outer metal shell is added. The wires are bundled together to form a component that connects the circuit. The wires in automotive wiring harnesses are also called low-voltage wires, which are different from ordinary household wires. Ordinary household wires are single-core copper wires with a certain degree of rigidity; while automotive wires are multi-core copper wires, some of which are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes, making them flexible and not easy to break.

[0003] However, currently, feeding messy wire harnesses one by one into the processing station in an orderly manner still relies on manual operation, which is not only inefficient but also prone to errors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated feeding and sorting device for automotive wiring harness processing. It mainly solves the problems that manual docking is not only inefficient, but also leads to defects due to inconsistent lengths of each wire entering the terminal.

[0015] As a further embodiment of the present invention, a plurality of guide covers are uniformly fixedly connected along the axis on the side of the straightening guide block near the force-applying wheel, and each guide cover corresponds to each contour groove.

[0016] As a further embodiment of the present invention, a plurality of baffles are fixedly connected to the top surface of the workbench, and the baffles are located between the arranging assembly and the straightening assembly.

The stop block passes through the limiting seat. A guide plate is provided on the top surface of the workbench, and the guide plate faces the placement box. A rubber plate is fixedly connected to the top surface of the workbench through a bracket. The rubber plate is located above the guide plate and is in contact with the terminal.

[0019] Compared with the prior art, the present invention provides an integrated feeding and sorting device for automotive wiring harness processing, which has the following beneficial effects:

[0020] 1. This invention achieves quantitative feeding by using a coil plate composed of inclined and vertical plates in the wire harness feeding component in conjunction with a limiting motor, thus avoiding multiple wire harnesses falling at the same time and causing jamming. At the same time, the wire harness pressing plate in the wire harness positioning component actively presses the wire harness under the action of the pressing plate, and with the help of the avoidance groove to avoid interference, it effectively prevents the wire harness from falling off due to bumps during the conveyor belt transportation process, thus improving the feeding stability.

[0021] 2. This invention uses a ball screw linear module to drive the smoothing positioning shell to move laterally. The positioning plate and the slotted photoelectric switch work together to achieve precise locking of the contouring slots in sequence. The smoothing and compacting block fixes the wire harness spacing. Then, the guide platform, guide pressure plate and partition cover in the guide assembly achieve physical isolation of multiple wire harnesses and uniform extension of the ends to a fixed length, ensuring consistent terminal crimping depth and avoiding tangling and misalignment.

[0022] 3. After the electric push rod pushes the moving seat forward to complete the crimping, the elastic deformation of the rubber plate and the outward turning action of the stop block around the torsion spring shaft automatically release the limit on the terminal when the push rod retracts. This allows the crimped wire harness to be unconstrained and slide naturally into the placement box along the guide plate. No manual material handling is required, realizing automatic unloading and collection of finished products and improving production efficiency. Attached Figure Description

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0049] Please see Figures 1-22 As shown, an integrated feeding and sorting equipment for automotive wire harness processing includes a workbench 1 and a placement box 2 disposed on one side of the workbench 1. The workbench 1 is used to place the processing station, while the placement box 2 is used to place the processed wire harness. The top surface of the workbench 1 is provided with an arrangement assembly 3 for centrally placing the wire harness before crimping. The arrangement assembly 3 includes a conveyor belt 31, a wire harness positioning component 32, a pressing plate 33, a wire harness transfer component 34, a photoelectric sensor 35, a wire harness feeding component 36, and an offset electric push rod 37.

[0050] It should be noted that the photoelectric sensor model 35 can be selected from WTX-RGS-30N. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0051] The wire harness loading component 36 includes a wire harness receiving shell 361, a quantity limiting motor 362, a quantity limiting baffle 363, a coil plate 364, a guide frame 365, and a clearance groove 366. In use, the wire harness is first poured into the wire harness receiving shell 361, which serves as a temporary storage compartment. The quantity limiting baffle 363 separates the storage area from the unloading area. The coil plate 364 consists of parallel inclined and vertical plates. The inclined plates block the wire harnesses stacked inside the wire harness receiving shell 361, ensuring that only one wire harness can pass through the passageway to the unloading area. The quantity limiting motor 362 drives the coil plate 364 to rotate periodically. As the coil plate 364 rotates, it lifts a single wire harness at a time, while the vertical plates prevent excess wire harnesses from falling, achieving quantitative unloading with a single rotation and preventing multiple wire harnesses from falling simultaneously and causing jamming. The wire harness passes through the guide frame 365 and falls vertically, precisely landing inside the wire harness positioning component 32 on the surface of the conveyor belt 31.

[0052] After the wire harness falls into the wire harness positioning component 32, the wire harness rests on the upper surface of the wire harness positioning plate 322. The wire harness pressure plate 323 naturally tilts upwards due to the side torsion spring, while the clearance groove 366 can prevent the wire harness pressure plate 323 from being blocked by the guide frame 365 when it passes through the guide frame 365. Subsequently, the conveyor belt 31 cooperates with the photoelectric sensor 35 to make the conveyor belt 31 carry the wire harness positioning component 32 forward. When the wire harness pressure plate 323 travels to the pressure plate 33 directly below it, the pressure plate 33 presses down on the wire harness pressure plate 323. The torsion spring is compressed and deformed, and the pressure plate closes downward to press the wire harness, preventing the wire harness from moving and completing the temporary fixation of the wire, preventing the wire harness from shaking and falling off during the conveyor belt 31's transport.

[0053] When the wire harness positioning component 32 moves with the wire harness to a point where it is detected by the photoelectric sensor 35, the conveyor belt 31 stops. At this time, the offset electric push rod 37 is activated. The push rod of the offset electric push rod 37 pushes the wire harness positioning plate 322 to move towards the wire harness transfer component 34 inside the positioning recess 321. The elastic rope 324 located on the bottom surface of the wire harness positioning plate 322 is stretched. Because the wire harness is squeezed by the wire harness pressure plate 323 when the wire harness positioning plate 322 is pushed, the wire harness will not be misaligned. Moreover, the offset electric push rod 37 pushes the wire harness positioning plate 322, not the wire harness itself, so the wire harness will not bend. Then the wire harness transfer component 34 transfers the wire harness. When the push rod retracts, the elastic rope 324 rebounds and resets the wire harness positioning plate 322. After the photoelectric sensor 35 detects that the wire harness has disappeared, the conveyor belt 31 continues to start, thus forming a cycle. The wire harness pressure plate 323 will continue to tilt upwards after it is no longer limited by the pressure plate 33.

[0054] Specifically, the operator neatly places the pre-cut and stripped wire harnesses into the wire harness receiving shell 361, starts the limited-number motor 362 to rotate at a constant speed and intermittently, and lowers one wire harness with each rotation of the winding plate 364. The wire harnesses fall vertically along the guide frame 365 onto the empty wire harness positioning plate 322 below. The conveyor belt 31 moves forward at a constant speed. When the wire harness pressing plate 323 passes the bottom surface of the pressing plate 33, it is forced to press down and tighten the wire harness. The conveyor belt 31 continues to move to the detection point of the photoelectric sensor 35. After the sensor senses the wire harness, it sends an electrical signal, and the offset electric push rod 37 extends instantly to push the wire harness positioning plate 322, ensuring that the wire harness axis is coaxial with the subsequent transfer and subsequent work station. After the alignment is completed, the conveyor belt 31 continues to send the wire harness to the wire harness transfer component 34.

[0055] When the wire harness moves to the wire harness transfer component 34, the finger cylinder 342 clamps the wire harness. Due to the shape of the wire harness positioning plate 322, it provides support for the bottom of the wire harness, preventing the wire harness from bending due to its flexibility during clamping. The inner side of the finger cylinder 342's gripper is equipped with a guide positioning block 346, and the wire harness limiting plate 343 is slidably fitted on the outer side of the guide positioning block 346. The guide rail 341 provides a linear movement track for the finger cylinder 342, and the two ends of the tension spring 344 are respectively connected to the gripper and the limiting plate. During the clamping operation, the gripper closes, and the wire harness is limited. Plate 343 and guide positioning block 346 will wrap the wire harness. At this time, one end of the wire harness is flush with one end of wire harness limiting plate 343. Then, the transfer electric push rod 345 is activated, causing finger cylinder 342 to drive the wire harness to the next process. After the wire harness limiting plate 343 contacts the next process, as the guide positioning block 346 continues to move, the wire harness limiting plate 343 is limited. The wire harness limiting plate 343 will slide on the surface of guide positioning block 346. At this time, one end of the wire harness will pass through the wire harness limiting plate 343, making it easier for one end of the wire harness to enter the next process.

[0056] When the finger cylinder 342 releases its grip on the wire harness and retracts, the wire harness limiting plate 343 will reset due to the tension of the tension spring 344.

[0057] To solve the technical problem of straightening five wire harnesses, this invention employs the following method: when one end of the wire harness moves toward the straightening component 4, the ball screw linear module 46 drives the straightening positioning shell 41 to move laterally. The positioning plate 411 moves synchronously with the shell. The slotted photoelectric switch 414 on the baffle 413 senses the insertion signal of the positioning plate 411. Upon receiving the signal, the module immediately locks and positions itself, thereby enabling individual contour slots to be aligned with the feed inlet in sequence. By sequentially switching the slot positions, five wire harnesses can be fed in batches.

[0058] The straightening motor 412 drives the upper and lower pairs of force-applying wheels 48 to rotate in opposite directions through the sprocket set. The contact surface of the two wheels relies on friction to pull the wire harness forward. The front guide cover 45 has a flared structure, which can gather up the raised and bent wire harness ends and guide the wire ends smoothly into the contour groove.

[0059] After the wire harness enters the contour groove, the wire harness guide plate 49 supports the lower side of the wire harness, and the upper limiting shell 410 restricts the upward bending of the wire harness. The double upper and lower limiting prevents the wire harness from coming out of the groove. After all the wire harnesses are filled, the first electric push rod 42 is straightened and the straightening and compaction block 44 is pressed down. The compaction block is embedded in the contour groove to lock the wire harness and fix the spacing of the wire harness arrangement. The second electric push rod 47 can push the entire ball screw linear module 46 to move forward axially, driving the entire wire harness to feed towards the guide assembly 5.

[0060] It should be noted that the ball screw linear module 46 achieves precise linear motion through the coordinated operation of various components: the slide table is the moving part, the ball screw and guide rail form the transmission core, the motor and coupling provide power, and the aluminum alloy profile and support base ensure structural stability. Furthermore, by cooperating with magnetic switches, proximity switches, or photoelectric switches, the precise control of the slide table displacement can be achieved. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0061] When the end of the first wire harness enters the gap of the force-applying wheel 48, the straightening motor 412 starts, and the force-applying wheel 48 frictionally pulls the wire harness through the guide cover 45 into the first contouring groove. The lower end of the wire harness falls on the wire harness guide plate 49, and the upper part is limited by the limiting shell 410. After the single wire feeding is completed, the ball screw linear module 46 moves laterally, and the positioning plate 411, in conjunction with the slot-type photoelectric switch 414, is precisely locked in the next slot, waiting for the next wire harness to be transferred and fed. The above actions are repeated to complete the loading of 5 wire harnesses into the independent contouring grooves. After all the wire harnesses are arranged, the straightening first electric push rod 42 moves downward, and the straightening compaction block 44 presses all the wire harnesses. Then the straightening second electric push rod 47 extends, pushing the ball screw linear module 46 to move as a whole towards the guide assembly 5. The wire harness guide plate 49 passively slides and retracts inside the straightening positioning shell 41, and the wire harness is pushed as a whole into the guide assembly 5.

[0062] The multiple guide grooves of the guide table 53 correspond one-to-one with the pressure blocks of the upper guide plate 54. The guide table 53 and the guide plate 54 are paired and installed with partition covers 55 on the same side. The upper and lower partition covers 55 are arranged alternately to physically separate adjacent wire harnesses and prevent multiple wires from tangling. The first electric push rod 52 of the guide drives the guide plate 54 to press down, and the pressure block is inserted into the guide groove to lock the wire harness. The length of the wire harness end extending out of the guide groove is fixed to achieve the standardization of the terminal insertion depth.

[0063] Five wire harnesses pushed from the straightening component 4 fall simultaneously into the wire harness guide groove of the guide table 53. The separator cover 55 is stuck in the gap between adjacent wire harnesses to isolate the wires. The first electric push rod 52 drives the guide pressure plate 54 to press down and the pressure block is embedded in the guide groove to fix the position of the wire harness. The ends of the wire harnesses extend out of a fixed length to meet the terminal crimping size requirements.

[0064] Two limiting seats 65 form a terminal mounting station. The stop block 66 normally extends inward under the action of the torsion spring shaft 67, limiting the metal terminal from both sides. The rubber plate 62 has elastic deformation capability. When the terminal is pushed forward and contacts the rubber plate 62, the rubber is compressed and indented. When the terminal is pulled back, it squeezes the stop block 66, overcomes the elastic force of the torsion spring, pushes the stop block 66 outward, automatically releases the terminal limit, and the finished wire harness slides down by its own weight.

[0065] The metal terminal to be crimped is manually inserted between the two limit seats 65 beforehand. The stop block 66 clamps the terminal under the action of the torsion spring to prevent it from shifting. The electric push rod 63 pushes the moving seat 61 forward, and the terminal sleeve is crimped at the exposed end of the wire harness. After crimping, the guide plate 54 is lifted to release the wire harness. The electric push rod 63 continues to push forward, and the terminal head squeezes the rubber plate 62 to deform it. The push rod begins to retract and reset. The terminal moves backward and squeezes the two stop blocks 66. The stop block 66 rotates outward around the torsion spring shaft 67 to open the limit. The crimped wire harness is unrestrained and slides naturally down the inclined surface of the guide plate 64, and finally falls into the side placement box 2 for storage. The single cycle process is completed, and the equipment automatically resets to prepare for the next round of wire harness processing.

[0066] It should be noted that in this application, the slotted photoelectric switch 414 is model EE-SX671. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0067] The working principle of this invention is as follows: The operator pours the cut and stripped wire harness into the wire harness receiving shell 361. The limiting motor 362 drives the winding plate 364 to rotate intermittently, releasing only one wire harness per revolution. The wire harness falls vertically into the wire harness positioning member 32 on the conveyor belt 31 via the guide frame 365. The wire harness lands on the wire harness positioning plate 322, and the side wire harness pressing plate 323 naturally tilts up due to the torsion spring. The avoidance groove 366 prevents the pressing plate from interfering with the guide frame. The conveyor belt 31 moves the wire harness positioning member 32 forward. When the wire harness pressing plate 323 reaches directly below the pressing plate 33, the pressing plate 33 presses down to close the pressing plate, compressing the torsion spring and thus pressing the wire harness to prevent it from falling off during transport. After the photoelectric sensor 35 detects that the wire harness has arrived, the conveyor belt 31 stops. The offset electric push rod 37 pushes the wire harness positioning plate 322 towards the wire harness transfer member 34, aligning the wire harness axis with the subsequent work station. Since the wire harness is fixed by the pressure plate, moving the positioning plate will not cause the wire harness to bend or shift. After the push rod retracts, the elastic rope 324 resets the wire harness positioning plate 322; the finger cylinder 342 clamps the wire harness, and the guide positioning block 346 on its gripper and the wire harness limiting plate 343 together wrap the wire harness, keeping it straight. The transfer electric push rod 345 drives the finger cylinder 342 to move along the guide rail 341, sending the wire harness to the straightening assembly 4. During this process, the wire harness limiting plate 343 is blocked by the next process, causing the end of the wire harness to protrude, facilitating its entry into the subsequent workstation. When the finger cylinder 342 releases and retracts, the tension spring 344 resets the wire harness limiting plate 343.

[0068] The ball screw linear module 46 drives the straightening positioning shell 41 to move laterally. The positioning plate 411 triggers the slotted photoelectric switch 414, causing each contouring slot to align with the feed inlet in sequence. The straightening motor 412 drives the upper and lower paired force-applying wheels 48 to rotate in opposite directions through the sprocket assembly. The traction wire harness passes through the guide cover 45 and enters the contouring slot. The wire harness guide plate 49 and the limiting shell 410 limit the upper and lower positions. After the five wire harnesses are sequentially inserted into the independent contouring slots, the first straightening electric push rod 42 presses down the straightening compaction block 44 to lock the wire harness. The second straightening electric push rod 47 pushes the entire wire harness into the guide assembly 5.

[0069] Five wire harnesses fall simultaneously into the guide groove of the guide table 53, and the separator 55 physically isolates adjacent wire harnesses. The first electric push rod 52 of the guide drives the guide pressure plate 54 to press down, and the pressure block is inserted into the guide groove to fix the wire harness, so that the ends of the wire harnesses protrude to a uniform length to meet the terminal crimping size requirements.

[0070] The metal terminal is manually inserted between the two limiting seats 65, and the stop 66 clamps the terminal under the action of the torsion spring shaft 67. The electric push rod 63 pushes the moving seat 61, so that the terminal sleeve is crimped at the end of the wire harness. After crimping, the guide plate 54 is released, and the electric push rod 63 continues to push forward, causing the terminal to deform by pressing the rubber plate 62; when the push rod retracts, the terminal moves backward and presses the stop 66 to flip outward, releasing the limiting position, and the finished wire harness slides naturally into the placement box 2 along the guide plate 64. The equipment automatically resets and begins the next cycle.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
