Description

Technical Field

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

[0002] The main reason why electrical wiring needs to be stripped at the end is to ensure the effective connection of the conductor, improve the conductivity and ensure safe use. The insulation layer on the outer layer of the wire is made of non-conductive materials (such as plastic or rubber). Its core function is to protect the internal conductor and prevent short circuits. However, at the end that needs to be connected, the insulation layer must be stripped to expose the metal conductor to achieve smooth transmission of current. In addition, stripping can also ensure the reliability of subsequent processes (such as crimping terminals, welding or access interfaces), so that the conductors are in close contact with the connecting parts, reducing signal attenuation or energy loss. Especially in high-voltage or high-precision wiring harness applications, precise stripping can avoid uneven contact resistance caused by residual insulation layer, thereby extending equipment life and reducing the probability of failure. Therefore, end stripping is a necessary step in electrical wiring to ensure conductivity, connection stability and safety.

[0003] A Chinese patent publication numbered CN118676806B discloses a stripping device for automotive wiring harnesses, which drives the stripping knife to move through a transmission screw, adjusts the spacing between multiple stripping knives, and implements a ring-cutting and stripping operation on wiring harnesses of different diameters; the protective skin outside the wiring harness can be ring-cut by the ring-shaped rotation of the stripping mechanism, and when the transmission pulley slides in the spiral section, the stripping mechanism rotates spirally, and the protective skin after ring cutting can be ejected when the stripping mechanism rotates; however, the technical solution still has the following defects; 1. Only one wire harness can be stripped at a time, which affects the overall processing efficiency; 2. Although the spiral rotation of the peeling mechanism can be used to push out the protective skin after circumcision, when the cut protective skin is hard and long, the side of the peeling knife will be subject to great resistance during the ejection process, which may easily lead to the risk of the peeling knife breaking and being damaged.

DETAILED DESCRIPTION

[0021] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 10 As shown, the present invention is an electrical wiring processing equipment, including a base 1 and a threading plate 2 vertically installed on the top of the base 1, a plurality of rotating parts 4 for the wire harness 3 to pass through and uniformly distributed in the circumferential direction are rotatably installed on the threading plate 2, a cutter 6 is symmetrically arranged on the side of the rotating part 4 away from the threading plate 2, and a linkage processing mechanism 5 is installed between the rotating part 4 and the threading plate 2, the linkage processing mechanism 5 is used to control the two cutters 6 to feed towards each other, and to control the cutter 6 to perform annular cutting on the outer skin of the wire harness 3, a peeling mechanism 7 is arranged on the side of the threading plate 2 away from the rotating part 4, the peeling mechanism 7 is used to position the wire harness 3 when the outer skin is cut, and the peeling mechanism 7 is used to separate the wire harness 3 from the conductor of the wire harness 3 after the outer skin of the wire harness 3 is cut.

[0023] It should be noted that, when in use, multiple wire harnesses 3 to be processed are passed through each rotating member 4 in turn, so that the cutter 6 corresponds to the part of the outer skin of the wire harness 3 that needs to be cut, and the peeling mechanism 7 is used to puncture and position the wire harness 3 passing through the rotating member 4. The other parts of the wire harness 3 that do not need to be peeled are clamped by an adjustable clamp (not shown in the figure), and the linkage processing mechanism 5 is started to drive the multiple rotating members 4 on the threading plate 2 to rotate synchronously, and cooperate with the cutters 6 symmetrically arranged on the rotating member 4, not only can the multiple wire harnesses 3 be synchronously annularly cut and processed, but also, in the process of the rotation of the rotating member 4, the linkage processing mechanism 5 can be used to drive the two cutters 6 symmetrically arranged on the rotating member 4 to intermittently approach each other, so that the cutter 6 is convenient for embedding into the outer skin of the wire harness 3, and the cutter 6 can be self-rotated during the feeding movement, so that the cutter 6 can be more easily cut into the outer skin of the wire harness 3 during feeding, which is beneficial to improve the cutting effect of the outer skin of the wire harness 3; After the outer skin of the wire harness 3 is cut off, the peeling mechanism 7 is controlled to move in the direction away from the threading plate 2. During the movement, a pulling force is applied to the cut outer skin of the wire harness 3, thereby facilitating the separation of the outer skin from the conductor of the wire harness 3. During the separation process, there is no need for the cutter 6 to squeeze the outer skin, so that the cutter 6 is not easily damaged, which is beneficial to increasing the service life.

[0024] like Figure 1 and Figure 5 As shown, the rotating member 4 includes a through-heart toothed disc 41 and a rotating tube 42 . The rotating tube 42 passes through the threading plate 2 and is coaxially connected to the through-heart toothed disc 41 . The rotating tube 42 is rotatably connected to the threading plate 2 .

[0025] It should be noted that a first bearing is installed between the rotating tube 42 and the threading plate 2. The first bearing not only allows the rotating tube 42 to rotate along the threading plate 2, but also facilitates the connection between the rotating tube 42 and the threading plate 2, so that the rotating tube 42 and the threading plate 2 will not be out of position.

[0026] like Figure 1 and Figure 3-Figure 4 As shown, the linkage processing mechanism 5 includes a driving component 51 and a rotating feeding component 52. The driving component 51 is installed on the threading plate 2, and the driving component 51 is used to drive multiple heart-shaped toothed discs 41 to rotate synchronously. The rotating feeding component 52 is installed between the heart-shaped toothed disc 41 and the threading plate 2, and the rotating feeding component 52 is used to drive the two cutters 6 to approach each other during the rotation of the heart-shaped toothed disc 41, and drive the cutter 6 to rotate when feeding.

[0027] It should be noted that the driving component 51, as a power source, can drive multiple concentric toothed discs 41 to rotate synchronously. During the rotation of the concentric toothed discs 41, the rotating feeding component 52 is linked, which not only facilitates the two cutters 6 on the threading plate 2 to intermittently approach each other, but also causes the cutter 6 to rotate during the feeding process, thereby facilitating the cutter 6 to cut into the outer skin of the wiring harness 3.

[0028] like Figure 2-Figure 3 As 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 is used to clamp the outer skin of the wire harness 3. The moving component 71 is installed on the base 1 and is used to drive the pneumatic clamping component 72 to translate.

[0029] It should be noted that the pneumatic clamping assembly 72 is used to facilitate the synchronous puncture, positioning and clamping of multiple wire harnesses 3 to be peeled at one time, and the moving assembly 71 is used to facilitate the horizontal movement of the pneumatic clamping assembly 72, so that after the outer skin of the wire harness 3 is cut off, the moving assembly 71 drives the pneumatic clamping assembly 72 to move away from the threading plate 2, so that the cut outer skin can be separated from the conductor of the wire harness 3.

[0030] like Figure 1 and Figure 4 As shown, the driving assembly 51 includes a first motor 511, an outer gear ring 512 and a connecting member 513. The connecting member 513 is fixedly installed between the inner rings of the outer gear ring 512. The outer gear ring 512 is meshed with multiple concentric toothed discs 41. The first motor 511 is installed on the side of the threading plate 2 away from the concentric toothed disc 41, and the output shaft of the first motor 511 is coaxially connected to the outer gear ring 512 through the connecting member 513.

[0031] 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 member 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, it can synchronously drive multiple concentric toothed discs 41 meshing with it to synchronously and adaptively rotate.

[0032] like Figure 1 and Figure 5-Figure 7 As shown, the rotary feed assembly 52 includes a fixing ring 522 with teeth 521, an L-shaped member 523, a driving gear 524, a telescopic member 525, a bevel gear 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 slot 43 for the rotating pin 529 to pass through is provided on the concentric toothed disk 41. The first fixing member 527 and the second fixing member 528 are both installed on a side of the concentric toothed disk 41 close to the threading plate 2. The fixed portion of the telescopic member 525 is rotatably connected to the first fixing member 527, and the movable portion of the telescopic member 525 is connected to the first fixing member 527. The second fixing member 528 is threadedly connected, and when the fixed part of the telescopic member 525 rotates, the movable part can be driven to rotate synchronously. The L-shaped member 523 is respectively sleeved with the rotating pin 529 and the movable part of the telescopic member 525. The two bevel gears 526 are meshed with each other and are respectively installed on the rotating pin 529 and the end of the telescopic member 525. The driving gear 524 is sleeved on the fixed part of the telescopic member 525. The fixing ring 522 is installed on the side of the threading plate 2 close to the through-heart toothed disk 41. The tooth 521 is partially arranged on the side of the fixing ring 522 away from the threading plate 2, and the tooth 521 is meshed with the driving gear 524.

[0033] It should be noted that, in this embodiment, the telescopic member 525 includes an outer cylinder 5251 with a limit groove 5252 and an inner rod 5253 with a limit key 5254, the inner rod 5253 extends into the outer cylinder 5251, and the limit key 5254 is slidably connected with the limit groove 5252, so that not only the outer cylinder 5251 can drive the inner rod 5253 to rotate synchronously, but also the inner rod 5253 can be relatively displaced with the outer cylinder 5251, and the inner rod 5253 is provided with a second fixing member 528 is threadedly connected to the outer thread. 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 be fed or retracted along the second fixing member 528, thereby driving the two cutters 6 to move toward or away from each other. In addition, in order to improve the feeding stability of the cutter 6, in this embodiment, a guide column 530 is installed on the L-shaped member 523, and the guide column 530 slides through the second fixing member 528. When the concentric toothed disk 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 excessively rotating, in this embodiment, the teeth 521 on the fixed ring 522 are partially arranged so that the outer cylinder 5251 will not excessively rotate when the concentric toothed disk 41 rotates one circle, so that the inner rod 5253 drives the cutter 6 to gradually cut in, so that the circular cutting operation of the outer skin of the wire harness 3 will be gradually fed inward, avoiding incomplete cutting of the outer skin of the wire harness 3 due to excessive feeding of the cutter 6 when the circular cutting operation is not completed.

[0034] like Figure 1-Figure 2 As shown, the moving assembly 71 includes a second motor 711, a screw rod 712, a slide rail 713 and a moving plate 714. The slide rail 713 is symmetrically installed on the top of the base 1. The moving plate 714 is slidably connected to the slide rail 713. The second motor 711 is installed on the upper surface of the base 1 near one end. The screw rod 712 is coaxially connected to the output end of the second motor 711, and the moving plate 714 is threadedly sleeved with the screw rod 712.

[0035] It should be noted that the second motor 711 in this embodiment is also a servo motor that can switch between forward and reverse directions. In order to improve the rotation stability of the screw rod 712, a bearing seat rotatably connected to the end of the screw rod 712 is installed on the top of the base 1. When the second motor 711 drives the screw rod 712 to rotate, it can drive the movable plate 714 to slide stably along the slide rail 713.

[0036] like Figure 2 and Figure 8-Figure 10 As shown, the pneumatic clamping assembly 72 includes a threading tube 721, an elastic sleeve 722, a negative pressure tube 723, a piston 724, a slide rod 725, a spring 726, a bracket 727, a negative pressure pipe 728 and an arc-shaped clamping plate 729 with a puncture. A plurality of threading tubes 721 are evenly inlaid and installed on the moving plate 714 in an annular shape. Two elastic sleeves 722 are respectively installed at the positions of the threading tubes 721 at both ends. A plurality of negative pressure tubes 723 are evenly distributed along the wall of the threading tube 721. The bracket 727 is installed on the negative pressure tube 72 At the inner cylinder wall near one end of the threading cylinder 721, the piston 724 is located in the negative pressure cylinder 723, the slide rod 725 slides 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 clamping plate 729 is located in the threading cylinder 721, and the arc clamping plate 729 is connected to one end of the slide rod 725 away from the piston 724, a plurality of punctures are evenly arranged on the side of the arc clamping plate 729 away from the slide rod 725, and the negative pressure pipe fitting 728 is installed between the plurality of threading cylinders 721.

[0037] It should be noted that the diameters of the two elastic sleeves 722 gradually decrease from the direction away from the movable plate 714, and the minimum diameter of the elastic sleeve 722 is smaller than the outer diameter of the wiring harness 3, so that when the wiring harness 3 passes through the elastic sleeve 722, the elastic sleeve 722 can be adaptively expanded by it, and the inner cavity of the threading tube 721 passing through the wiring harness 3 is in a closed state. When the inner cavity of the threading tube 721 is pumped to a negative pressure state by the negative pressure pipe 728, the piston 724 will approach the threading tube 721 along the negative pressure tube 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 clamp 729 to press the wiring harness 3. In this embodiment, the puncture length on the arc clamp 729 is less than the thickness of the outer skin of the wiring harness 3, thereby realizing the puncture positioning and clamping of the wiring harness 3.

[0038] like Figure 1 and Figure 8 As shown, the negative pressure pipe fitting 728 includes a connecting pipe 7281, an exhaust pipe 7282 and a solenoid valve 7283. The connecting pipe 7281 is installed between two adjacent threading tubes 721, and the connecting pipe 7281 is connected to the inner cavity of the threading tube 721. The solenoid valve 7283 is installed on one of the connecting pipes 7281, and the exhaust pipe 7282 is connected to one of the connecting pipes 7281.

[0039] It should be noted that, in this embodiment, one end of the exhaust pipe 7282 away from the connecting pipe 7281 is connected to a negative pressure device (not shown in the figure), and the negative pressure device can be installed on the side wall of the movable plate 714. The multiple connecting pipes 7281 facilitate the connection of multiple threading tubes 721 in series, so that each threading tube 721 maintains a connected state. When the negative pressure state needs to be cancelled, the solenoid valve 7283 is controlled to open so that the outside air can enter the inner cavity of the threading tube 721 through the connecting pipe 7281, so that the compressed spring 726 drives the piston 724 (such as Fig. 9 as shown) reset.

[0040] An embodiment of the present invention provides an electrical wiring processing method, comprising the following steps: Step 1: Pass the multiple wire harnesses 3 to be peeled through each rotating member 4 in turn, and adjust the end thereof to maintain a set distance with the threading plate 2, and then start the peeling mechanism 7 to puncture, clamp and position the outer skin of each wire harness 3; 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 cutter 6 to revolve along the wire harness 3. During the rotation of the rotating member 4, the linkage processing mechanism 5 is used to drive the two cutters 6 to rotate in a process of approaching each other, thereby performing a circular feed cutting on the outer skin of the wire harness 3; Step three: After the outer skin of the wire harness 3 is cut off, the peeling mechanism 7 is controlled to move in a direction away from the threading plate 2, thereby pulling the cut outer skin of the wire harness 3 apart from the conductor of the wire harness 3, and the stripping process of the end of the wire harness 3 is completed.

[0041] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
