Description

Technical Field

[0001] The invention relates to the technical field of cable terminal crimping, in particular to an automatic crimping machine for multi-core cable terminals for a wind turbine generator set. Background Art

[0002] Cable terminal crimping machines are necessary equipment for crimping wires. Existing crimping machines are divided into hydraulic crimping machines, large-tonnage crimping machines (punches), insulated terminal crimping machines, split-type crimping machines with crimping pliers, hand-cranked hydraulic crimping machines and other types.

[0003] The cables used in wind turbines are mostly large-diameter multi-core cables, which usually need to be crimped with hexagonal terminals when used. Due to the large diameter of the cables, the size of the crimped terminals is also relatively large. There are few automatic terminal crimping devices on the market that are suitable for the wind power industry. The crimping effect of existing large square hexagonal terminal crimping equipment is not ideal, and it is difficult to keep the crimped part of the terminal in a standard regular hexagonal shape, which affects the appearance quality of the product.

[0004] Since the cables used by wind turbines are mostly multi-core cables, the outer layer of the cables is an insulating rubber, and there are multiple core wires in the cables, and the core of each core wire is also covered with a layer of insulating rubber. When crimping the terminals, it is necessary to first peel off the outer insulating rubber at the end of the cable to expose the core wire, and then peel off the insulating rubber at the end of each core wire in the cable, and then crimp the terminal at the end of each core wire. The whole operation process is relatively cumbersome. At present, the production of cable terminal crimping is mostly semi-automatic, which is to first complete the stripping of the outer insulating rubber of the cable in the previous stripping equipment, and then transfer the cable to the next stripping equipment to complete the stripping of the insulating rubber at the end of each core wire, and then transfer the stripped cable to the crimping equipment to complete the terminal crimping. This semi-automatic method has low production efficiency, and because the multi-core cables used in wind turbines have a large diameter and the intermediate products are heavy, manual operation is required during the operation of each device and the transportation between devices, and the labor intensity of the operator is also high.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0022] like Figures 1 to 4 As shown, an automatic crimping machine for multi-core cable terminals for a wind turbine generator system includes a frame 100 on which a crimping assembly 200, a terminal conveying assembly 300 and a wire feeding assembly 500 are arranged.

[0023] The crimping assembly 200 includes a crimping hydraulic cylinder 201, a crimping swing arm 202, a crimping turntable 220, a crimping fixed plate 210 and six crimping blocks 230. The crimping fixed plate 210 is fixedly connected to the frame 100, the crimping turntable 220 is coaxially rotatably connected to the crimping fixed plate 210, one end of the crimping swing arm 202 is fixedly connected to the crimping turntable 220, the other end of the crimping swing arm 202 is rotatably connected to one end of the crimping hydraulic cylinder 201, and the other end of the crimping hydraulic cylinder 201 is rotatably connected to the frame 100. When the crimping hydraulic cylinder 201 is extended or retracted, the crimping turntable 220 can be driven to rotate on the crimping fixed plate 210 within a certain angle range.

[0024] The crimping block 230 is arranged between the crimping fixed disk 210 and the crimping rotating disk 220. The crimping rotating disk 220 is provided with a regular hexagonal slot 211. One side of the six crimping blocks 230 is respectively slidably connected with the six sides of the regular hexagonal slot 221. The crimping fixed disk 210 is evenly distributed with six crimping slots 211 on the circumference. The six crimping blocks 230 are respectively slidably connected with the six crimping slots 221 on the side away from the crimping rotating disk 220. Figure 3 , Figure 4 As shown, the shapes of the six crimping blocks 230 are adapted to form an iris structure of the crimping assembly 200 as a whole, and a regular hexagonal crimping hole 231 is formed between the six crimping blocks 230. When the crimping hydraulic cylinder 201 drives the crimping turntable 220 to rotate through the crimping swing arm 202, the six crimping blocks 230 can be driven to move simultaneously to make the crimping hole 231 larger or smaller, and the crimping hole 231 is always kept in a regular hexagon during the process.

[0025] The axis of the crimping hole 231 is arranged in the horizontal direction, and the center of the crimping turntable 220 and the center of the crimping fixed disk 210 are both provided with through holes adapted to the crimping hole 231, and the wire feeding assembly 500 and the terminal conveying assembly 300 are respectively arranged on both sides of the crimping hole 231. When in use, the wire feeding assembly 500 is used to first pass the stripped end of the cable or core wire through the central through hole of the crimping turntable 220 and then extend it into the center position of the crimping hole 231, and the terminal conveying assembly 300 is used to pass the crimping end of the terminal (which is a hollow cylinder) through the central through hole of the crimping fixed disk 210 and then extend it into the center position of the crimping hole 231, at which time the crimping end of the terminal is sleeved outside the stripped end of the cable or core wire; then the piston rod of the crimping hydraulic cylinder 201 is retracted, driving the crimping turntable 220 to rotate to shrink the crimping hole 231, and the crimping operation at this location can be completed. The crimping assembly 200 using the iris structure has a relatively simple structure and can maintain the crimping position in a regular hexagon during the crimping process of large square hexagonal terminals, thereby ensuring the appearance quality of the product.

[0026] The terminal conveying assembly 300 is used to extend the crimping end of the terminal into the center position of the crimping hole 231, and a variety of structures can be selected to achieve this. Figure 5 , Figure 6 As shown, the terminal conveying assembly 300 includes a terminal conveying seat 310, an electric push rod 320 and a terminal conveying mechanism.

[0027] A vertical slide groove 311 and a horizontal slide groove 312 are provided on the terminal conveying seat 310. The vertical slide groove 311 is arranged along the vertical direction. The vertical slide groove 311 is used to load the wiring terminals. The wiring terminals can slide downward in the vertical slide groove 311 under the action of their own weight; the electric push rod 320 is installed at the bottom end of the vertical slide groove 311, and the telescopic end of the electric push rod 320 can be extended into the vertical slide groove 311 to block the wiring terminals in the vertical slide groove 311. By controlling the telescopic action of the electric push rod 320, it is possible to automatically control whether the wiring terminals at the bottom end of the vertical slide groove 311 are released.

[0028] The horizontal slide groove 312 is arranged perpendicular to the vertical slide groove 311 and is adapted to be parallel to the axial direction of the crimping hole 231. The bottom end of the vertical slide groove 311 is arranged directly above the horizontal slide groove 312. Figure 6As shown, the terminal conveying mechanism includes a terminal conveying slider 330, a terminal conveying cylinder 331, a first terminal clamping cylinder 332 and a second terminal clamping cylinder 333. The terminal conveying slider 330 is slidably arranged in the horizontal slide groove 312. The terminal conveying cylinder 331 is used to make the terminal conveying slider 330 slide in the horizontal slide groove 312. The first terminal clamping cylinder 332 and the second terminal clamping cylinder 333 are both fixed and vertically installed on the terminal conveying slider 330. The telescopic end of the first terminal clamping cylinder 332 is fixedly installed with an upper clamping plate 335, and the second end The telescopic end of the sub-clamping cylinder 333 is fixedly installed with a lower clamping plate 334, and the first terminal clamping cylinder 332 and the second terminal clamping cylinder 333 can respectively drive the upper clamping plate 335 and the lower clamping plate 334 to rise and fall; a clamping space is formed between the upper clamping plate 335 and the lower clamping plate 334, and the clamping space is adapted to the end of the terminal away from its crimping end (this end is the terminal, used for connecting multi-core cables in a wind turbine, and is usually flat). When the upper clamping plate 335 and the lower clamping plate 334 are brought close to each other, the end of the terminal away from its crimping end can be clamped.

[0029] When the terminal conveying assembly 300 is used, Figure 5 , Figure 6 As shown, the telescopic end of the electric push rod 320 is first extended to block the terminal in the vertical slide groove 311, and the terminal is loaded in the vertical slide groove 311. At this time, the terminal at the bottom is positioned; then the piston rod of the conveying cylinder 331 is extended to drive the terminal conveying slider 330 to slide toward the crimping hole 231 until the end of the terminal at the bottom away from its crimping end is located between the upper clamping plate 335 and the lower clamping plate 334; then, under the action of the first terminal clamping cylinder 332 and the second terminal clamping cylinder 333, the upper clamping plate 335 and the lower clamping plate 334 move closer to each other to complete the clamping of the terminal; then the telescopic end of the electric push rod 320 is retracted , driven by the first terminal clamping cylinder 332 and the second terminal clamping cylinder 333, the clamped terminal is moved down to the center position basically facing the crimping hole 231; then the telescopic end of the electric push rod 320 extends to block other terminals; then the piston rod of the conveying cylinder 331 continues to extend, and the crimping end of the terminal clamped by the upper clamping plate 335 and the lower clamping plate 334 is conveyed to the center position of the crimping hole 231; after the crimping of the terminal is completed, the upper clamping plate 335 and the lower clamping plate 334 move away from each other and release, and the piston rod of the conveying cylinder 331 is retracted, and the terminal conveying slider 330 returns to the initial position to wait for the conveying of the next terminal. Thus, the conveying assembly 300 can extend the crimping end of each terminal into the center position of the crimping hole 231 in an orderly manner under automatic control according to the set program.

[0030] The wire feeding assembly 500 is used to insert the stripped end of the cable or core wire into the center position of the crimping hole 231, and a variety of structures can be selected to achieve this. In this embodiment, the wire feeding assembly in the automatic stripping device for the end of a multi-core cable for a wind turbine generator set in the Chinese invention patent application (application number: 202411443688.0) can be selected, and its structure is as follows: Figure 8 As shown, the wire feeding assembly 500 includes a wire feeding frame 510 and a wire feeding mechanism. The wire feeding frame 510 is connected to the frame 100, and the wire feeding mechanism includes an upper wire feeding roller 511, a lower wire feeding roller 512, a wire feeding motor 513 and a first cylinder 514. The upper wire feeding roller 511 and the lower wire feeding roller 512 are both arranged in the longitudinal direction, and the longitudinal direction refers to the horizontal direction and is perpendicular to the axis of the crimping hole 231. The upper wire feeding roller 511 is arranged directly above the lower wire feeding roller 512, and a wire feeding area is formed between the upper wire feeding roller 511 and the lower wire feeding roller 512, and the wire feeding area is directly opposite to the center position of the crimping hole 231. The lower wire feeding roller 512 is rotatably connected to the wire feeding frame 510, and the wire feeding motor 513 is installed on the wire feeding frame 510. The wire feeding motor 513 is used to drive the lower wire feeding roller 512 to rotate; the first cylinder 514 is vertically installed on the wire feeding frame 510, and the telescopic end of the first cylinder 514 is fixedly connected to the core shaft, and the upper wire feeding roller 511 is rotatably sleeved on the core shaft. When in use, the end of the stripped cable is first extended into the above-mentioned wire feeding area from the side away from the crimping assembly 200; then the first cylinder 514 is started, and the upper wire feeding roller 511 is driven to descend through the core shaft, and the end of the cable is clamped between the upper wire feeding roller 511 and the lower wire feeding roller 512; then the wire feeding motor 513 is started to extend the cable end to the center position in the crimping hole 231.

[0031] As can be seen from the above, as an implementation method (Example 1), the crimping assembly 200, the terminal conveying assembly 300 and the wire feeding assembly 500 can be used together to realize the automatic crimping of the end of a single-core cable. Specifically, during crimping, the wire feeding assembly 500 first extends the cable end to the center position of the crimping hole 231 in the above manner, and the terminal conveying assembly 300 simultaneously conveys the crimping end of the conveying terminal to the center position of the crimping hole 231 in the above manner; thereafter, the crimping assembly 200 can complete the crimping process in the above manner. After completing one crimping, the piston rod of the crimping hydraulic cylinder 201 in the crimping assembly 200 extends to enlarge the crimping hole 231, loosening the clamping of the crimping position of the terminal to prepare for the next crimping; the first terminal clamping cylinder 332 and the second terminal clamping cylinder 333 in the terminal conveying assembly 300 can drive the upper clamping plate 335 and the lower clamping plate 334 to separate, loosening the clamping of the end of the terminal, and the various components in the terminal conveying assembly 300 automatically return to wait for the next conveying terminal. In the wire feeding assembly 500, the wire feeding motor 513 drives the lower wire feeding roller 512 to reverse, and the crimped single-core cable is transported away from the crimping assembly 200. After most of the cable is located on the side of the wire feeding area away from the crimping assembly 200, the first cylinder 514 drives the upper wire feeding roller 511 to rise, and releases the clamping of the cable. The cable is separated from the wire feeding assembly 500 under the action of its own weight and the rotation of the lower wire feeding roller 512. At this time, the wire feeding assembly 500 can wait for the next wire feeding.

The wire splitting slider 402 is slidably connected to the bracket 401, and the sliding direction of the wire splitting slider 402 is arranged along the longitudinal direction. The wire splitting push rod 403 can use an electric push rod that can accurately control the position, which is used to drive the wire splitting slider 402 to slide; the lifting cylinder 404 is fixedly connected to the wire splitting slider 401, and the lifting cylinder 404 is arranged in the vertical direction. As shown Fig.10As shown, the wire-dividing mechanism includes a connecting block 410, two wire clamping devices and two wire-digging devices. The connecting block 410 is fixedly connected to the telescopic end of the lifting cylinder 404, and the lifting cylinder 404 can drive the connecting block 410 to rise and fall. A symmetry axis is also defined at a position parallel to the axis of the crimping hole 231; the wire clamping device includes a clip 411 and a spring 412, the clip 411 is slidably connected to the connecting block 410, the two ends of the spring 412 are respectively connected to the clip 411 and the connecting block 410, and the two clips 411 are symmetrically arranged along the above-mentioned symmetry axis; the wire-digging device includes a paddle 413 and a paddle cylinder 414, the paddle 413 is slidably connected to the connecting block 410, the paddle cylinder 414 is used to drive the paddle 413 to slide, and the two paddles 413 are symmetrically arranged along the above-mentioned symmetry axis.

[0033] As another embodiment (Example 2), the aforementioned crimping assembly 200, the terminal conveying assembly 300, the wire feeding assembly 500 and the aforementioned wire distribution assembly 400 are used in combination to realize automatic crimping of the ends of multi-core cables. Specifically, during implementation, after the wire feeding area of ​​the crimping assembly 200 receives the multi-core cable whose core wire ends have been stripped, the wire feeding motor 513 is first rotated to adjust the exposed core wire portion of the multi-core cable to be located between the upper wire feeding roller 511 and the lower wire feeding roller 512; then the upper wire feeding roller 511 and the lower wire feeding roller 512 are maintained in a clamping state on the core wire portion of the multi-core cable, and the wire feeding motor 513 is rotated forward and reversed multiple times until the core wires are arranged flat (arranged in a single row horizontally, without stacking in the vertical direction); then the wire feeding motor 513 is started to extend the ends of the flatly arranged core wires to directly below the connection block 410; then the lifting air is used. The cylinder 404 drives the connecting block 410 to descend, and drives the paddle 413 and the clamp 411 to be inserted into the row of core wires. At this time, the core wire to be crimped is clamped between the two clamps 411 and located between the two paddles 413; then the two paddle cylinders 414 drive the two stripping rollers 413 to open to both sides, pushing the remaining core wires to both sides; then the wire feed motor 513 drives the lower wire feeding roller 512 to rotate to move the cable toward the crimping assembly 200, and the core wire located between the two paddles 413 is extended into the crimping hole 231; then the crimping of the core wire can be completed through the terminal conveying assembly 300 and the crimping assembly 200. Since the wire-dividing slider 402 can slide longitudinally under the drive of the wire-dividing push rod 403, after the previous core wire is crimped, the connection block 410 is first driven up by the lifting cylinder 404 to separate the clamping piece 411 and the paddle 413 from the core wire, and the paddle cylinder 414 drives the paddle 413 to reset; then the wire-in motor 513 is rotated to flatten each core wire again and return each core wire end to the bottom of the connection block 410; then the wire-dividing push rod 403 drives the wire-dividing slider 402 to slide longitudinally for a set distance; then the lifting cylinder 404 drives the connection block 410 to descend, driving the paddle 413 and the clamping piece 411 to reset Insert into the row of core wires, at this time, another core wire is clamped between the two clamps 411 and located between the two paddles 413; then the two paddle cylinders 414 drive the two stripping pieces 413 to open to both sides, push the remaining core wires to both sides, and drive the wire dividing slider 402 to slide longitudinally through the wire dividing push rod 403 so that the core wire is clamped by the clamps 411 and moves horizontally to a position basically aligned with the center of the crimping hole 231; then the wire feed motor 513 drives the lower wire feeding roller 512 to rotate to move the cable toward the crimping assembly 200, and extends the core wire located between the two paddles 413 into the crimping hole 231 to complete the crimping.It can be seen that the branching assembly 400 can realize the core wire separation function. After separation, under the action of the wire feeding assembly 500, the ends of each core wire of the multi-core cable can be respectively transported to the crimping hole 231 to complete the crimping. Therefore, by making the branching assembly 400 cooperate with the aforementioned crimping assembly 200, the terminal conveying assembly 300, and the wire feeding assembly 500, the crimping operation of the ends of each core wire of the multi-core cable can be automatically completed.

[0034] Further, such as Figure 8 As shown, the wire feeding assembly 500 also includes a wire pressing mechanism, which includes an upper pressing plate 516, a lower pressing plate 517 and a second cylinder 515. The lower pressing plate 517 is fixedly connected to the wire feeding frame 510, and the lower pressing plate 517 is arranged on a side of the lower wire feeding roller 512 close to the crimping hole 231, and the lower pressing plate 517 is parallel to the axis of the lower wire feeding roller 512, and the height of the lower pressing plate 517 is adapted to the height of the lower wire feeding roller 512. The upper pressure plate 516 is arranged in parallel just above the lower pressure plate 517, and the second cylinder 515 is vertically installed on the wire feeding frame 510. The telescopic end of the second cylinder 515 is fixedly connected to the upper pressure plate 516. The upper pressure plate 516 can be driven to rise and fall by the second cylinder 515. When the upper pressure plate 516 descends, it moves closer to the lower pressure plate 517. Before the crimping assembly 200 works, the upper pressure plate 516 and the lower pressure plate 517 can clamp and fix the cable or core wire, which is beneficial to ensure the crimping quality.

[0035] Further, such as Figure 8 As shown, the wire feeding assembly 500 also includes a cutting mechanism, which includes an upper cutting knife 518, a lower cutting knife 519 and a third cylinder 520. The lower cutting knife 519 is fixedly connected to the wire feeding frame 510, and the lower cutting knife 519 is arranged on the side of the lower wire feeding roller 512 away from the lower pressing plate 517, and the height of the lower cutting knife 519 is adapted to the height of the lower wire feeding roller 512; the upper cutting knife 518 is adapted to be arranged directly above the lower cutting knife 519, and the third cylinder 520 is vertically installed on the wire feeding frame 510, and the telescopic end of the third cylinder 520 is fixedly connected to the upper cutting knife 518, and the upper cutting knife 518 can be driven to rise and fall by the third cylinder 520, and when the upper cutting knife 518 descends to engage with the lower cutting knife 519, the cable can be cut away from the end where it is crimped. Before the cutting mechanism works, the cable cutting position can be adjusted by the carrying mechanism of the wire feeding assembly 500, thereby obtaining a cable product of a set length.

[0036] According to the above-mentioned Example 1 and Example 2, the automatic production of single-core cable and multi-core cable products in the crimping process can be realized respectively. However, only in this embodiment, the production material is the intermediate product whose cable end has been stripped. It should be understood that when implementing this embodiment, it is also necessary to set an input mechanism at the front end of the wire feeding assembly 500, which is used to input the stripped intermediate products into the wire feeding assembly 500 in sequence under automatic control, thereby realizing continuous crimping production.

[0037] Further, such as Figure 1 , Figure 2 As shown, a stripping assembly 600 is also provided. The stripping assembly 600 and the crimping assembly 200 are arranged side by side in the longitudinal direction. The wire feeder 510 is slidably connected to the frame 100, and the wire feeder 510 can slide on the frame 100 in the longitudinal direction. The stripping assembly 600 can realize the automatic stripping operation of the cable end. When in use, the production raw material can be a cable coil. First, the end of the cable to be crimped is extended into the wire feeder 510 through an external traction device and clamped by the wire feed mechanism; then the wire feeder 510 slides to the position opposite to the stripping assembly 600 to complete the stripping operation of the cable end; then the wire feeder 510 slides to the position opposite to the crimping assembly 200 to complete the crimping operation in the above manner; then the cutting mechanism of the wire feeder 500 works to cut the cable according to the set length; then the collection of the cable products is completed. Therefore, after adding the stripping assembly 600, full-automatic production from stripping to crimping can be realized, and the crimped cable segment products are directly produced from the cable coil.

[0038] It should be noted that during the collection process of the above-mentioned cable products, the wire feed motor 513 can drive the lower wire feed roller 512 to reverse in the aforementioned manner, and the crimped cable can be transported in a direction away from the crimping assembly 200 to complete the separation of the cable segment product from the wire feed assembly 500; and since the wire feed frame 510 is slidably connected to the frame 100, after the crimping is completed, the wire feed frame 510 can also be slid to a collection position away from the stripping assembly 600 and the crimping assembly 200, and the wire feed motor 513 can directly drive the lower wire feed roller 512 to rotate forward to complete the separation of the cable segment product from the wire feed assembly 500.

[0039] The above-mentioned wire feeding assembly 500, stripping assembly 600, crimping assembly 200 and terminal conveying assembly 300 can form an automatic crimping device, which can realize the automatic crimping production of one end of a single-core cable in the above-mentioned manner (after adding the branching assembly 400, the automatic crimping production of one end of a multi-core cable can be realized). It should also be noted that since the wire feeding frame 510 can slide longitudinally on the frame 100, and since the wire feeding mechanism in the wire feeding assembly 500 can realize the front and back conveyance of the cable, when there are two wire feeding frames 510 arranged opposite to each other, the cable can be transferred from one of the wire feeding frames 510 to the other wire feeding frame 510; therefore, during implementation, the automatic crimping device can be used in two sets together, and the two sets of automatic crimping devices are arranged back to back. After one set of the automatic crimping devices completes the crimping of one end of the cable, it is transferred to the other set of automatic crimping devices to complete the crimping of the other end of the cable, thereby realizing the production of cable segment products with both ends crimped.

[0040] When implementing it, Figure 2 , Figure 7As shown, the wire feeding assembly 500 also includes a wire feeding motor 521, a driving pulley 523, a synchronous belt 522 and a driven pulley 524. The driving pulley 523 and the driven pulley 524 are both rotatably connected to the frame 100. The driving pulley 523 and the driven pulley 524 are connected by the synchronous belt 522. One side of the synchronous belt 522 is fixedly connected to the wire feeding frame 510. The wire feeding motor 521 is used to drive the driving pulley 523 to rotate. The wire feeding motor 521 can realize rapid sliding and automatic control of the wire feeding frame 510 on the frame 100. The use of the synchronous belt mechanism is conducive to accurate positioning of the wire feeding frame 510.

[0041] The stripping assembly 600 can be used in various structural forms for stripping the insulating rubber at the end of the cable (or core wire). In this embodiment, Figure 1 , Figure 2 , Figures 11 to 15 As shown, the stripping assembly 600 includes a drive mechanism and a stripping mechanism.

The driving shaft 610 and the first transmission shaft 611 are connected by the first transmission belt 614, and the first transmission shaft 611 and the intermediate transmission shaft 612 are connected by the second transmission belt 615. A transmission gear A616 is fixedly sleeved on the intermediate transmission shaft 612, a transmission gear B617 is fixedly sleeved on the second transmission shaft 613, and the transmission gear A is meshed with the transmission gear B.

During implementation, a peeling motor 601 and a reducer 602 are also provided on the frame 100 . The peeling motor 601 is used to rotate the driving shaft 610 .

[0043] The peeling mechanism includes a slide 620, a cutting friction roller 621, a cutting gear 622, a cutting belt 623, an upper rack 624, a lower rack 625, a connecting rod 626, a crank 627, a crank shaft 628, a sliding gear 629 and a half gear 630. The cutting friction roller 621 and the cutting gear 622 are rotatably connected to the slide 620, the axis of the cutting friction roller 621 and the axis of the cutting gear 622 are both parallel to the driving shaft 610, the cutting friction roller 621 is adapted to be arranged between the first friction roller 618 and the second friction roller 619, the cutting friction roller 621 and the cutting gear 622 are connected by a cutting belt 623, the upper rack 624 and the lower rack 625 are both slidably connected to the slide 620 and can slide in the vertical direction, the tooth surface of the upper rack 624 and the tooth surface of the lower rack 625 are arranged oppositely, and the cutting gear 622 is meshed with the upper rack 624 and the lower rack 625 at the same time. The slide 620 is slidably connected to the frame 100, the sliding direction of the slide 620 on the frame 100 is horizontal and perpendicular to the drive shaft 610, the crank shaft 628 is rotatably connected to the frame 100, one end of the crank 627 is fixedly sleeved on the crank shaft 628, the other end of the crank 627 is rotatably connected to one end of the connecting rod 626, the other end of the connecting rod 626 is rotatably connected to the slide 620, the sliding gear 629 is fixedly sleeved on the crank shaft 628, the half gear 630 is fixedly sleeved on the drive shaft 610, and the half gear 630 is meshed with the sliding gear 629. In a specific implementation, a material receiving box 603 is also fixedly provided on the slide 620, and the material receiving box 603 is used to receive the peeled insulating rubber.

[0044] Furthermore, there are two peeling mechanisms in the peeling assembly 600, and the two peeling mechanisms are arranged side by side in a direction parallel to the driving shaft 610, and the phases of the two half gears 630 are 180 degrees different. The upper rack 624 and the lower rack 625 of one peeling mechanism are respectively fixedly mounted with an upper ring cutter 631 and a lower ring cutter 632, and the assembly is Fig.12 , Fig.13 The upper rack 624 and the lower rack 625 of the other peeling mechanism are respectively fixed with an upper bevel cutter 633 and a lower bevel cutter 634, and the assembly is Fig.14 , Fig.15 The bottom end of the upper circular cutter 631 and the top end of the lower circular cutter 632 are respectively provided with mutually adapted arc-shaped cutting edges for stripping the outer insulating rubber of the multi-core cable; the bottom end of the upper bevel cutter 633 and the top end of the lower bevel cutter 634 are respectively provided with mutually adapted inclined cutting edges for stripping the insulating rubber of each core wire in the multi-core cable.

[0045] The specific structural principle of the stripping assembly 600 and the working process of its coordinated action with the wire feeding assembly 500 to realize continuous automatic stripping of the cable end or the core wire end are detailed in the Chinese invention patent application for automatic stripping device for multi-core cable ends for wind turbines (application number: 202411443688.0), which will not be repeated here. Since the wire feeding frame 510 in the wire feeding assembly 500 can slide longitudinally, it can automatically complete the position switching between the stripping assembly 600, the wire crimping assembly 200 and the collection area after cutting under automatic control, and according to the above, the crimping assembly 200, the terminal conveying assembly 300 and the wire feeding assembly 500 can cooperate to realize the automatic crimping of the end of a single-core cable, and the addition of the branching assembly 400 can realize the automatic crimping of the ends of each core wire in a multi-core cable, so that the entire equipment can realize the full process of automated continuous production of the cable end from stripping to crimping, with high production efficiency. Specifically, when one stripping mechanism is set in the stripping assembly 600 as described above, the stripping assembly 600, the wire feeding assembly 500, the crimping assembly 200, and the terminal conveying assembly 300 work together to realize the fully automatic continuous crimping production of single-core cables; when two stripping mechanisms are set in the stripping assembly 600 as described above, the stripping assembly 600, the wire feeding assembly 500, the wire distribution assembly 400, the crimping assembly 200, and the terminal conveying assembly 300 work together to realize the fully automatic continuous crimping production of multi-core cables.

[0046] It should be noted that when used for the fully automatic continuous crimping production of multi-core cables, since the wire splitting assembly 400 needs to separate each core wire and then crimp them separately during the crimping process, the process time of the crimping process is relatively long, and when the drive shaft 610 in the stripping assembly 600 rotates continuously, the ring cutting mechanism and the beveling mechanism operate according to a certain action cycle. If the process connection is directly performed, the stroke of the slide 620 in the ring cutting mechanism and the beveling mechanism needs to be increased and the rotation speed of the drive shaft 610 needs to be reduced, which will affect the production efficiency. Therefore, in the specific implementation, a set of automatic crimping mechanisms is formed by each set of the wire feeding assembly 500, the wire splitting assembly 400, the crimping assembly 200 and the terminal conveying assembly 300. A set of the automatic crimping mechanisms can be set on both sides of the stripping assembly 600. When one set of the automatic crimping mechanisms is in the crimping process, the other set of the automatic crimping mechanisms is in the stripping process, thereby better realizing the process connection and improving the production efficiency.
