Description

Technical Field

[0001] The present invention relates to the technical field of electrical wiring processing, and particularly relates to an electrical wiring processing device and method. Background Art

[0002] End stripping processing of electrical wiring is mainly to ensure effective connection of conductors, improve electrical conductivity, and ensure safety in use. The insulating layer on the outer layer of the wire is composed of non-conductive materials (such as plastic or rubber), and its core function is to protect the internal conductor and prevent short circuits. However, at the end where connection is required, the insulating layer must be stripped to expose the metal conductor, so as to achieve smooth transmission of current. In addition, stripping can also ensure the reliability of subsequent processes (such as crimping terminals, welding, or connecting to interfaces), enabling the conductor to be in close contact with the connecting components, reducing signal attenuation or energy loss. Especially in high-voltage or high-precision wire harness applications, precise stripping can avoid uneven contact resistance caused by residual insulating layer, thereby extending the service life of the device and reducing the probability of failures. Therefore, end stripping is a necessary step in electrical wiring to ensure electrical conductivity, connection stability, and safety.

[0003] In a patent with the Chinese patent publication number CN118676806B, a car wire harness stripping device is disclosed. The movement of the stripping knife is driven by a transmission screw to adjust the distance between multiple stripping knives, so as to perform circumferential cutting and stripping operations on wire harnesses with different diameters; the circumferential rotation of the stripping mechanism can perform circumferential cutting operations on the protective skin outside the wire harness. When the transmission pulley slides in the spiral section, the stripping mechanism rotates spirally, and when the stripping mechanism rotates, the circumferentially cut protective skin can be pushed out; however, this technical solution still has the following defects;

[0004] 1. Each time, only one wire harness can be processed for stripping, which affects the overall processing efficiency;

[0005] 2. Although the circumferentially cut protective skin can be pushed out by the spiral rotation of the stripping mechanism, when the cut protective skin is hard and long in texture, a great resistance force will act on the side of the stripping knife during the pushing-out process, which easily leads to the risk of damage to the stripping knife. Summary of the Invention

[0006] The purpose of the present invention is to provide an electrical wiring processing device and method, which solve the problems that the existing wire harness stripping device is inconvenient for processing multiple wire harnesses simultaneously and the tool is easily damaged during the peeling process.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] In a first aspect of the present invention, an electrical wiring processing device is provided, which includes a base and a wire threading board vertically installed on the top of the base. A plurality of rotating members through which a wire harness passes and are circumferentially evenly distributed are rotatably installed on the wire threading board. On one side of the rotating member away from the wire threading board, cutting knives are symmetrically arranged, and a linkage processing mechanism is installed between the rotating member and the wire threading board. The linkage processing mechanism is used to control the two cutting knives to feed towards each other, and is used to control the cutting knives to perform annular cutting on the outer skin of the wire harness. A peeling mechanism is arranged on the side of the wire threading board away from the rotating member. The peeling mechanism is used to position the outer skin of the wire harness during the cutting of the outer skin of the wire harness, and the peeling mechanism is used to separate the outer skin from the conductor of the wire harness after the cutting of the outer skin of the wire harness is completed;

[0009] The peeling mechanism includes a moving component and a pneumatic clamping component. The pneumatic clamping component is installed on the moving component, and the pneumatic clamping component is used to clamp the outer skin of the wire harness. The moving component is installed on the base, and the moving component is used to drive the pneumatic clamping component to translate.

[0010] As a further aspect of the present invention: The rotating member includes a through-hole tooth disc and a rotating tube.

[0012] As a further aspect of the present invention: The driving component includes a first motor, an external gear ring and a connecting piece. The connecting piece is fixedly installed between the inner rings of the external gear ring. The external gear ring is meshed with a plurality of through-hole tooth discs. The first motor is installed on the side of the wire threading board away from the through-hole tooth disc, and the output shaft of the first motor is coaxially connected to the external gear ring through the connecting piece.

[0013] As a further solution of the present invention: The rotary feeding assembly includes a fixed ring with teeth, an L-shaped member, a driving gear, a telescopic member, bevel gears, a first fixing member, a second fixing member, and a rotating pin. The rotating pin is coaxially connected to the cutting tool. A through groove for the rotating pin to pass through is formed on the through-hole tooth disc. The first fixing member and the second fixing member are both installed on the side of the through-hole tooth disc close to the wire threading plate. The fixed part of the telescopic member is rotatably connected to the first fixing member, and the movable part of the telescopic member is threadedly connected to the second fixing member. When the fixed part of the telescopic member rotates, it can drive the movable part to rotate synchronously. The L-shaped member is sleeved on the rotating pin and the movable part of the telescopic member respectively. The two bevel gears mesh with each other and are respectively installed at the ends of the rotating pin and the telescopic member. The driving gear is sleeved on the fixed part of the telescopic member. The fixed ring is installed on the side of the wire threading plate close to the through-hole tooth disc. The toothed part is arranged on the side of the fixed ring away from the wire threading plate, and the teeth mesh with the driving gear.

[0014] As a further solution of the present invention: The moving assembly includes a second motor, a lead screw, a slide rail, and a moving plate. The slide rails are symmetrically installed on the top of the base. The moving plate is slidably connected to the slide rails. The second motor is installed on the upper surface of the base near one end. The lead screw is coaxially connected to the output end of the second motor, and the moving plate is threadedly sleeved on the lead screw.

[0015] As a further solution of the present invention: The pneumatic clamping assembly includes a wire threading cylinder, an elastic seal, a negative pressure cylinder, a piston, a slide rod, a spring, a bracket, a negative pressure pipe fitting, and an arc-shaped clamping plate with punctures. A plurality of the wire threading cylinders are evenly and annularly embedded and installed on the moving plate. Two of the elastic seals are respectively installed at the two ends of the wire threading cylinder. A plurality of the negative pressure cylinders are evenly distributed along the inner wall of the wire threading cylinder. The bracket is installed on the inner wall of the negative pressure cylinder near the wire threading cylinder at one end. The piston is located inside the negative pressure cylinder. The slide rod slidably passes through the bracket and is connected to the piston. The spring is installed between the piston and the bracket. The arc-shaped clamping plate is located inside the wire threading cylinder, and the arc-shaped clamping plate is connected to the end of the slide rod away from the piston. A number of the punctures are evenly arranged on the arc-shaped clamping plate and on the side away from the slide rod. The negative pressure pipe fitting is installed between a plurality of the wire threading cylinders.

[0016] As a further solution of the present invention: The negative pressure pipe fitting includes a connecting pipe, an air extraction pipe, and an electromagnetic valve. The connecting pipe is installed between two adjacent wire threading cylinders, and the connecting pipe is communicated with the inner cavity of the wire threading cylinder. The electromagnetic valve is installed on one of the connecting pipes. The air extraction pipe is communicated with one of the connecting pipes.

[0017] The second aspect of the present invention provides an electrical wiring processing method, which is applied to the above-mentioned electrical wiring processing equipment, and includes the following steps:

[0018] Step 1: Pass multiple wire harnesses to be peeled through each rotating part in sequence. After adjusting the distance between their ends and the wire threading plate to a set value, start the peeling mechanism to perform puncture clamping and positioning on the outer skins of each wire harness.

[0019] Step 2: Use the linkage processing mechanism to drive each rotating part to rotate synchronously, so that the rotating part drives the cutting tool to revolve along the wire harness. During the rotation of the rotating part, use the linkage processing mechanism to drive the two cutting tools to rotate themselves while approaching each other, so as to perform circular feeding cutting on the outer skin of the wire harness.

[0020] Step 3: After the outer skin of the wire harness is cut off, control the peeling mechanism to move away from the wire threading plate, so as to pull the cut-off outer skin of the wire harness away from the conductor of the wire harness, and the peeling process of the end of the wire harness can be completed.

[0021] Advantages of the present invention:

[0022] 1. In the present invention, multiple rotating parts distributed annularly and equidistantly facilitate the passage of multiple wire harnesses at one time. The peeling mechanism is used to conveniently perform puncture pressing and positioning on the outer skins of the wire harnesses passing through the rotating parts, so that the wire harnesses will not shake in position during the outer skin cutting process, thus effectively ensuring the stability of processing.

[0023] 2. In the present invention, the cutting tools symmetrically arranged on the rotating parts facilitate the outer skin cutting process of the wire harnesses passing through the rotating parts. Starting the linkage processing mechanism conveniently drives the multiple rotating parts on the wire threading plate to rotate synchronously. Cooperating with the cutting tools symmetrically arranged on the rotating parts, it is convenient to perform synchronous circular cutting on multiple wire harnesses, thus greatly improving the efficiency of the wire harness peeling process. In addition, during the rotation of the rotating part, using the linkage processing mechanism can not only drive the two cutting tools symmetrically arranged on the rotating part to gradually approach intermittently, facilitating the cutting tools to embed into the outer skin of the wire harness, but also enable the cutting tools to rotate themselves during the feeding movement. Since the cutting tools in the rotating state are more likely to cut into the outer skin of the wire harness during feeding, it is beneficial to improve the cutting effect of the outer skin of the wire harness.

[0024] 3. In the present invention, through the linkage processing mechanism, during the circular cutting of the cable by the cutting tools, the two cutting tools can gradually approach each other and feed slowly, which not only facilitates the processing of wire harnesses of different sizes, but also enables the circular cutting operation and the feeding operation of the cutting tools to be synchronized, which is beneficial to improving the processing efficiency.

[0025] 4. In the present invention, the peeling mechanism not only facilitates the positioning of the wire harness before cutting, improves the processing stability, but also facilitates the separation of the cut outer skin from the conductor of the wire harness after the outer skin of the wire harness is cut. During the separation process, there is no need for the cutting tool to squeeze the outer skin, so that the cutting tool is not easily damaged, which is beneficial to improving the service life.

Detailed implementation mode

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 - 10 shown, the present invention is an electrical wiring processing device, including a base 1 and a wire threading board 2 vertically installed on the top of the base 1. A plurality of rotating parts 4 through which the wire harness 3 passes and are circumferentially evenly distributed are rotatably installed on the wire threading board 2. Cutting tools 6 are symmetrically arranged on one side of the rotating part 4 away from the wire threading board 2. A linkage processing mechanism 5 is installed between the rotating part 4 and the wire threading board 2. The linkage processing mechanism 5 is used to control the two cutting tools 6 to feed towards each other and is used to control the cutting tools 6 to perform circular cutting on the outer skin of the wire harness 3. A peeling mechanism 7 is arranged on the side of the wire threading board 2 away from the rotating part 4. The peeling mechanism 7 is used to position the wire harness 3 during the cutting of the outer skin of the wire harness 3 and is used to separate it from the conductor of the wire harness 3 after the cutting of the outer skin of the wire harness 3 is completed.

[0040] It should be noted that during use, multiple wire harnesses 3 to be processed are sequentially passed through each rotating member 4, so that the cutting knife 6 corresponds to the part of the outer skin of the wire harness 3 that needs to be cut. The wire stripping mechanism 7 is used to perform puncture positioning on the wire harness 3 passing through the rotating member 4. Other parts of the wire harness 3 that do not need to be stripped are clamped by an adjustable fixture (not shown in the figure). The linkage processing mechanism 5 is started to drive the multiple rotating members 4 on the wire threading plate 2 to rotate synchronously. Cooperating with the cutting knives 6 symmetrically arranged on the rotating member 4, not only can the multiple wire harnesses 3 be subjected to synchronous circular cutting processing, but also during the rotation of the rotating member 4, by using the linkage processing mechanism 5, not only can the two cutting knives 6 symmetrically arranged on the rotating member 4 be driven to gradually approach intermittently, which is convenient for the cutting knives 6 to embed into the outer skin of the wire harness 3, but also the cutting knives 6 can rotate automatically during the feeding movement, which can make the cutting knives 6 more easily cut into the outer skin of the wire harness 3, and is beneficial to improving the cutting effect of the outer skin of the wire harness 3;

[0041] After the outer skin of the wire harness 3 is completely cut off, the wire stripping mechanism 7 is controlled to move away from the wire threading plate 2. During the movement, a pulling force is applied to the cut-off outer skin of the wire harness 3, so as to facilitate the separation of the outer skin from the conductor of the wire harness 3. During the separation process, there is no need for the cutting knife 6 to squeeze the outer skin, so that the cutting knife 6 is not easily damaged, which is beneficial to improving the service life.

[0042] As Figure 1 and Figure 5 shown, the rotating member 4 includes a through-hole tooth disc 41 and a rotating tube 42. The rotating tube 42 passes through the wire threading plate 2 and is coaxially connected to the through-hole tooth disc 41, and the rotating tube 42 is rotatably connected to the wire threading plate 2.

[0043] It should be noted that a first bearing is installed between the rotating tube 42 and the wire threading plate 2. By using the first bearing, not only can the rotating tube 42 rotate along the wire threading plate 2, but also it is convenient to connect the rotating tube 42 to the wire threading plate 2, so that the position between the rotating tube 42 and the wire threading plate 2 will not be disengaged.

[0044] As Figure 1 and Figures 3 - 4 shown, the linkage processing mechanism 5 includes a driving component 51 and a rotary feeding component 52. The driving component 51 is installed on the wire threading plate 2, and the driving component 51 is used to drive multiple through-hole tooth discs 41 to rotate synchronously. The rotary feeding component 52 is installed between the through-hole tooth disc 41 and the wire threading plate 2. The rotary feeding component 52 is used to drive the two cutting knives 6 to approach each other during the rotation of the through-hole tooth disc 41, and drive the cutting knives 6 to rotate automatically during the feeding of the cutting knives 6.

[0045] It should be noted that the driving component 51, as a power source, can drive multiple hollow tooth discs 41 to rotate synchronously. During the rotation of the hollow tooth discs 41, the rotary feed component 52 is linked, which not only facilitates driving the two cutting tools 6 on the wire threading plate 2 to approach intermittently and gradually, but also makes the cutting tools 6 rotate during the process of driving the cutting tools 6 to feed, facilitating the cutting tools 6 to cut into the outer skin of the wire harness 3.

[0046] As Figures 2 - 3 shown, the peeling mechanism 7 includes a moving component 71 and a pneumatic clamping component 72. The pneumatic clamping component 72 is installed on the moving component 71, and the pneumatic clamping component 72 is used to clamp the outer skin of the wire harness 3. The moving component 71 is installed on the base 1, and the moving component 71 is used to drive the pneumatic clamping component 72 to translate.

[0047] It should be noted that the pneumatic clamping component 72 is used to conveniently perform synchronous piercing positioning and clamping on multiple wire harnesses 3 to be peeled and processed at one time. The moving component 71 is used to conveniently control the pneumatic clamping component 72 to move horizontally. Thus, when the outer skin of the wire harness 3 is cut off and the moving component 71 drives the pneumatic clamping component 72 to move away from the wire threading plate 2, the cut-off outer skin can be separated from the conductor of the wire harness 3.

[0048] As Figure 1 and Figure 4 shown, the driving component 51 includes a first motor 511, an outer gear ring 512, and a connecting piece 513. The connecting piece 513 is fixedly installed between the inner rings of the outer gear ring 512. The outer gear ring 512 is meshed with multiple hollow tooth discs 41. The first motor 511 is installed on the side of the wire threading plate 2 away from the hollow tooth discs 41, and the output shaft of the first motor 511 is coaxially connected to the outer gear ring 512 through the connecting piece 513.

[0049] It should be noted that the first motor 511 in this embodiment is a servo motor that can control forward and reverse rotation. The center line of the connecting piece 513 coincides with the axis of the outer gear ring 512. When the first motor 511 is started to drive the outer gear ring 512 to rotate, multiple hollow tooth discs 41 meshed with it can be synchronously driven to rotate adaptively.

[0050] As Figure 1 and Figures 5 - 7As shown in the figure, the rotary feed assembly 52 includes a fixed ring 522 with teeth 521, an L-shaped member 523, a driving gear 524, a telescopic member 525, bevel gears 526, a first fixing member 527, a second fixing member 528, and a rotating pin 529. The rotating pin 529 is coaxially connected to the cutter 6. A through groove 43 for the rotating pin 529 to pass through is formed on the through-hole tooth disc 41. Both the first fixing member 527 and the second fixing member 528 are installed on the side of the through-hole tooth disc 41 close to the wire threading plate 2. The fixed part of the telescopic member 525 is rotatably connected to the first fixing member 527, and the movable part of the telescopic member 525 is threadedly connected to the second fixing member 528. When the fixed part of the telescopic member 525 rotates, it can drive the movable part to rotate synchronously. The L-shaped member 523 is sleeved on the rotating pin 529 and the movable part of the telescopic member 525 respectively. The two bevel gears 526 are meshed with each other and are installed at the ends of the rotating pin 529 and the telescopic member 525 respectively. The driving gear 524 is sleeved on the fixed part of the telescopic member 525. The fixed ring 522 is installed on the side of the wire threading plate 2 close to the through-hole tooth disc 41. Part of the teeth 521 is arranged on the side of the fixed ring 522 away from the wire threading plate 2, and the teeth 521 are meshed with the driving gear 524.

[0051] It should be noted that in this embodiment, the telescopic member 525 includes an outer cylinder 5251 with a limiting groove 5252 and an inner rod 5253 with a limiting key 5254. The inner rod 5253 extends into the outer cylinder 5251, and the limiting key 5254 is slidably connected to the limiting groove 5252. Thus, not only can the outer cylinder 5251 drive the inner rod 5253 to rotate synchronously, but also the inner rod 5253 can have a relative displacement with respect to the outer cylinder 5251. The inner rod 5253 is provided with an external thread threadedly connected to the second fixing member 528. When the outer cylinder 5251 drives the inner rod 5253 to rotate, since the inner rod 5253 is threadedly connected to the second fixing member 528, the inner rod 5253 will feed or retract along the second fixing member 528, thereby driving the two cutters 6 to move towards or away from each other. In addition, in order to improve the stability of the feeding of the cutter 6, in this embodiment, a guiding column 530 is installed on the L-shaped member 523, and the guiding column 530 slidably penetrates through the second fixing member 528.

[0052] When the through-hole tooth disc 41 rotates, it will synchronously drive the driving gear 524 to revolve along the teeth 521 on the fixed ring 522. In order to prevent the outer cylinder 5251 from rotating excessively, in this embodiment, part of the teeth 521 on the fixed ring 522 is arranged such that the outer cylinder 5251 will not rotate excessively when the through-hole tooth disc 41 rotates one circle. Thus, the inner rod 5253 drives the cutter 6 to gradually cut in, and the circumferential cutting operation of the outer skin of the wire harness 3 will gradually feed inwards, avoiding incomplete cutting of the outer skin of the wire harness 3 due to excessive feeding of the cutter 6 before the circumferential cutting operation is completed.

[0053] As Figures 1 - 2As shown, the moving component 71 includes a second motor 711, a lead screw 712, a slide rail 713, and a moving plate 714. The slide rails 713 are symmetrically installed on the top of the base 1. The moving plate 714 is slidably connected to the slide rails 713. The second motor 711 is installed on the upper surface of the base 1 near one end. The lead screw 712 is coaxially connected to the output end of the second motor 711, and the moving plate 714 is threadedly sleeved on the lead screw 712.

[0054] It should be noted that the second motor 711 in this embodiment is also a servo motor that can switch between forward and reverse rotations. To improve the rotational stability of the lead screw 712, a bearing block rotatably connected to the end of the lead screw 712 is installed on the top of the base 1. When the second motor 711 drives the lead screw 712 to rotate, it can drive the moving plate 714 to slide stably along the slide rails 713.

[0055] As Figure 2 and Figures 8 - 10 As shown, the pneumatic clamping component 72 includes a wire threading cylinder 721, an elastic seal 722, a negative pressure cylinder 723, a piston 724, a slide rod 725, a spring 726, a bracket 727, a negative pressure pipe fitting 728, and an arc-shaped clamping plate 729 with punctures. A plurality of wire threading cylinders 721 are evenly installed in a ring on the moving plate 714. Two elastic seals 722 are respectively installed at the two ends of the wire threading cylinder 721. A plurality of negative pressure cylinders 723 are evenly distributed along the wall of the wire threading cylinder 721. The bracket 727 is installed on the inner wall of the negative pressure cylinder 723 near one end of the wire threading cylinder 721. The piston 724 is located inside the negative pressure cylinder 723. The slide rod 725 slidably penetrates through the bracket 727 and is connected to the piston 724. The spring 726 is installed between the piston 724 and the bracket 727. The arc-shaped clamping plate 729 is located inside the wire threading cylinder 721, and the arc-shaped clamping plate 729 is connected to the end of the slide rod 725 away from the piston 724. A number of punctures are evenly arranged on the arc-shaped clamping plate 729 on the side away from the slide rod 725. The negative pressure pipe fitting 728 is installed between a plurality of wire threading cylinders 721.

[0056] It should be noted that the diameters of the two elastic seals 722 gradually decrease in the direction away from the moving plate 714. The minimum diameter of the elastic seal 722 is smaller than the outer diameter of the wire harness 3. When the wire harness 3 passes through the elastic seal 722, the elastic seal 722 can be adaptively expanded by it, and the inner cavity of the wire threading cylinder 721 through which the wire harness 3 passes is in a closed state. When the inner cavity of the wire threading cylinder 721 is evacuated to a negative pressure state by the negative pressure pipe fitting 728, the piston 724 will move closer to the wire threading cylinder 721 along the negative pressure cylinder 723, and at the same time drive the slide rod 725 to slide along the bracket 727 and compress the spring 726, so that the slide rod 725 drives the arc-shaped clamping plate 729 to tightly clamp the wire harness 3. In this embodiment, the puncture length on the arc-shaped clamping plate 729 is smaller than the outer skin thickness of the wire harness 3, so as to realize the puncture positioning and clamping of the wire harness 3.

[0057] As Figure 1 andFigure 8 As shown, the negative pressure pipe fitting 728 includes a connecting pipe 7281, an air extraction pipe 7282, and a solenoid valve 7283. The connecting pipe 7281 is installed between two adjacent wire threading cylinders 721, and the connecting pipe 7281 communicates with the inner cavity of the wire threading cylinder 721. The solenoid valve 7283 is installed on one of the connecting pipes 7281, and the air extraction pipe 7282 is connected to one of the connecting pipes 7281.

[0058] It should be noted that in this embodiment, the end of the air extraction pipe 7282 away from the connecting pipe 7281 is connected to a negative pressure device (not marked in the figure). The negative pressure device can be installed on the side wall of the moving plate 714. The multiple connecting pipes 7281 facilitate the series connection of multiple wire threading cylinders 721, so that each wire threading cylinder 721 remains in a connected state. When it is necessary to cancel the negative pressure state, the solenoid valve 7283 is controlled to open so that external air can enter the inner cavity of the wire threading cylinder 721 through the connecting pipe 7281, facilitating the reset of the compressed spring 726 to drive the piston 724 (as Figure 9 shown).

[0059] An embodiment of the present invention provides an electrical wiring processing method, including the following steps:

[0060] Step 1: Pass multiple wire harnesses 3 to be peeled through each rotating member 4 in sequence. After adjusting the distance between their ends and the wire threading plate 2 to a set distance, start the peeling mechanism 7 to perform puncture clamping and positioning on the outer skins of each wire harness 3.

[0061] Step 2: Use the linkage processing mechanism 5 to drive each rotating member 4 to rotate synchronously, so that the rotating member 4 drives the cutting knife 6 to revolve along the wire harness 3. During the rotation of the rotating member 4, use the linkage processing mechanism 5 to drive the two cutting knives 6 to rotate themselves while approaching each other, thereby performing circular feed cutting on the outer skin of the wire harness 3.

[0062] Step 3: After the outer skin of the wire harness 3 is cut off, control the peeling mechanism 7 to move away from the wire threading plate 2, thereby pulling the cut-off outer skin of the wire harness 3 away from the conductor of the wire harness 3, and the peeling process of the end of the wire harness 3 can be completed.
