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 wind turbines. Background Art

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

[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 equipment suitable for the wind power industry on the market. The crimping effect of existing large square hexagonal terminal crimping equipment is not ideal, and it is difficult to maintain the standard shape of the regular hexagon at the crimping point of the terminal, which affects the appearance quality of the product.

[0004] Because wind turbine cables are mostly multi-core cables with an outer layer of insulation rubber and multiple cores, each core is also covered with a layer of insulation rubber. When crimping terminals, the outer insulation rubber must first be stripped from the cable ends to expose the cores. The insulation rubber must then be stripped from the ends of each core within the cable, and then the terminals must be crimped onto each core. This process is quite cumbersome. Currently, cable terminal crimping is mostly semi-automated, with the outer insulation rubber being stripped from the cable in a previous stripping machine. The cable is then transferred to the next stripping machine to strip the insulation rubber from each core. The stripped cable is then transferred to the crimping machine to complete the terminal crimping. This semi-automatic method has low production efficiency. Furthermore, due to the large diameter of the multi-core cables used in wind turbines and the heavy weight of the intermediate products, manual operation is required during the operation of each device and during transfer between devices, which is labor-intensive for operators.

Thus, the coordinated action of the crimping assembly, terminal conveyor assembly, and wire feed assembly can achieve automatic crimping of the end of a single-core cable.

[0026] A branching assembly is provided, which can realize the core wire separation function. After separation, the ends of each core wire of the multi-core cable can be respectively transported to the crimping hole under the action of the wire feeding assembly to complete the crimping. Therefore, the crimping operation of each core wire end of the multi-core cable can be automatically completed under the coordinated action of the branching assembly, crimping assembly, terminal conveying assembly and wire feeding assembly.

[0027] A stripping assembly is provided, which works in conjunction with the wire feed assembly to achieve continuous, automated stripping of cable ends or individual wire ends within a cable. The wire feed assembly's longitudinally sliding frame automatically switches positions between the stripping assembly, crimping assembly, and collection area after cutting. This allows the entire equipment to achieve fully automated, continuous production of single-core and multi-core cable ends, from stripping to crimping, with high production efficiency.

[0043] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0044] like Figures 1 to 4 As shown, an automatic crimping machine for multi-core cable terminals for wind turbines includes a frame 100 on which a crimping assembly 200, a terminal conveying assembly 300 and a wire feeding assembly 500 are arranged.

[0045] 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, it can drive the crimping turntable 220 to rotate within a certain angle range on the crimping fixed plate 210.

[0046] 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 221. One side of the six crimping blocks 230 is respectively slidably connected with the six sides of the regular hexagonal slot 221. Six crimping slots 211 are evenly distributed on the circumference of the crimping fixed disk 210. The six crimping blocks 230 are respectively slidably connected with the six crimping slots 211 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.

[0047] The axis of the crimping hole 231 is arranged horizontally. 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. The wire feeding assembly 500 and the terminal conveying assembly 300 are respectively arranged on either side of the crimping hole 231. During use, the wire feeding assembly 500 first passes the stripped end of the cable or core wire through the central through-hole of the crimping turntable 220 and then into the center of the crimping hole 231. The terminal conveying assembly 300 then passes the crimping end of the terminal (which is a hollow cylinder) through the central through-hole of the crimping fixed disk 210 and then into the center of the crimping hole 231. At this point, the crimping end of the terminal is sleeved over the stripped end of the cable or core wire. The piston rod of the crimping hydraulic cylinder 201 is then retracted, driving the crimping turntable 220 to rotate and shrink the crimping hole 231, thereby completing the crimping operation at that location. 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.

[0048] 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 used 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.

[0049] The terminal conveying seat 310 is provided with a vertical slide groove 311 and a horizontal slide groove 312. The vertical slide groove 311 is arranged in 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. 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.

[0050] The horizontal chute 312 is arranged perpendicular to the vertical chute 311 and is adapted to be parallel to the axial direction of the crimping hole 231. The bottom end of the vertical chute 311 is arranged just above the horizontal chute 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 the wind turbine, usually in a flat shape). When the upper clamping plate 335 and the lower clamping plate 334 are close to each other, the end of the terminal away from its crimping end can be clamped.

[0051] When the terminal conveying assembly 300 is in use, 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 311, and the terminal is loaded in the vertical slide 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 a position substantially facing the center of the crimping hole 231; the telescopic end of the electric push rod 320 is then extended to block the other terminals; the piston rod of the conveying cylinder 331 is then further extended to convey the crimping end of the terminal clamped by the upper clamping plate 335 and the lower clamping plate 334 to the center of the crimping hole 231; after the crimping of the terminal is completed, the upper clamping plate 335 and the lower clamping plate 334 are separated from each other and released, and the piston rod of the conveying cylinder 331 is retracted, and the terminal conveying slider 330 returns to its initial position to wait for the conveyance of the next terminal. Thus, the conveying assembly 300 can automatically control the crimping end of each terminal in an orderly manner according to the set program to extend it into the center of the crimping hole 231.

[0052] 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. A variety of structures can be used 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 system in the Chinese invention patent application (application number: 202411443688.0) can be used. 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, which 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, which is directly opposite the center position of the crimping hole 231. The lower wire feed roller 512 is rotatably connected to the wire feed frame 510, and the wire feed motor 513 is mounted on the wire feed frame 510. The wire feed motor 513 is used to drive the lower wire feed roller 512 to rotate. The first cylinder 514 is vertically mounted on the wire feed frame 510. The telescopic end of the first cylinder 514 is fixedly connected to the core shaft, and the upper wire feed roller 511 is rotatably mounted on the core shaft. During use, the stripped cable end 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 activated, and the core shaft drives the upper wire feed roller 511 to descend, clamping the cable end between the upper wire feed roller 511 and the lower wire feed roller 512; then the wire feed motor 513 is activated to extend the cable end to the center position within the crimping hole 231.

[0053] As can be seen from the above, as an embodiment (Example 1), the crimping assembly 200, the terminal conveying assembly 300, and the wire feed assembly 500 are used together to automatically crimp the ends of single-core cables. Specifically, during crimping, the wire feed assembly 500 first inserts the cable end into the center of the crimping hole 231 in the manner described above. The terminal conveying assembly 300 then simultaneously conveys the crimping end of the conveying terminal to the center of the crimping hole 231 in the manner described above. The crimping assembly 200 then completes the crimping process in the manner described above. 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 retract to prepare for the next conveying of the terminal. In the wire feeding assembly 500, the wire feeding motor 513 drives the lower wire feeding roller 512 to reverse, and the single-core cable after crimping 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.

[0054] Further, such as Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 As shown, a line splitting assembly 400 is also provided, and the line splitting assembly 400 includes a bracket 401, a line splitting slider 402, a line splitting push rod 403, a lifting cylinder 404 and a line splitting mechanism. The bracket 401 is fixedly set on the frame 100, and the bracket 401 is set on the side of the crimping assembly 200 close to the wire feeding assembly 500. The line splitting slider 402 is slidably connected to the bracket 401, and the sliding direction of the line splitting slider 402 is set along the longitudinal direction. The line splitting push rod 403 can be an electric push rod that can accurately control the position, which is used to drive the line splitting slider 402 to slide; the lifting cylinder 404 is fixedly connected to the line splitting slider 401, and the lifting cylinder 404 is set in the vertical direction. As shown Figure 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 move up and down. 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, and 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, and 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.

[0055] 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, it first rotates the wire feed motor 513 to adjust the exposed core wire portion of the multi-core cable to be located between the upper wire feed roller 511 and the lower wire feed roller 512; then, the upper wire feed roller 511 and the lower wire feed roller 512 are kept in a clamped state on the core wire portion of the multi-core cable, and the wire feed motor 513 is rotated forward and reversed multiple times until the core wires are arranged flatly (arranged in a single row horizontally, without stacking in the vertical direction); then, the wire feed 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, driving the pick 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 is located between the two picks 413; then the two wire-pulling cylinders 414 drive the two picks 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 picks 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 line-dividing slider 402 can slide longitudinally under the drive of the line-dividing push rod 403, after the previous core wire is crimped, the connecting block 410 is first driven to rise by the lifting cylinder 404, so that the clip 411 and the paddle 413 are separated from the core wire, and the paddle 413 is driven to reset by the line-dividing cylinder 414; then the line-feeding motor 513 is rotated to flatten each core wire again and make the end of each core wire return to the bottom of the connecting block 410; then the line-dividing push rod 403 drives the line-dividing slider 402 to slide longitudinally to a set distance; then the lifting cylinder 404 drives the connecting block 410 to descend, driving the paddle 413 and the clip 411 Inserted into the row of core wires, at this time, the other core wire is clamped between the two clamps 411 and located between the two picks 413; then the two wire-pushing cylinders 414 drive the two picks 413 to open to both sides, pushing the remaining core wires to both sides, and driving the wire-pushing slider 402 to slide longitudinally through the wire-pushing 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-feeding motor 513 drives the lower wire feeding roller 512 to rotate so that the cable moves toward the crimping assembly 200, and the core wire located between the two picks 413 is extended into the crimping hole 231 to complete the crimping.It can be seen from this that the branching component 400 can realize the core wire separation function. After separation, under the action of the wire feeding component 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 component 400 cooperate with the aforementioned crimping component 200, the terminal conveying component 300, and the wire feeding component 500, the crimping operation of the ends of each core wire of the multi-core cable can be automatically completed.

[0056] 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 is arranged on a side of the lower wire feeding roller 512 close to the crimping hole 231. 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 parallel to and directly 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.

[0057] Further, such as Figure 8 As shown, the wire feeding assembly 500 also includes a cutting mechanism, which includes an upper cutting blade 518, a lower cutting blade 519, and a third cylinder 520. The lower cutting blade 519 is fixedly connected to the wire feeding frame 510 and is arranged on the side of the lower wire feeding roller 512 away from the lower pressure plate 517. The height of the lower cutting blade 519 is adapted to the height of the lower wire feeding roller 512. The upper cutting blade 518 is adapted to be arranged directly above the lower cutting blade 519. The third cylinder 520 is vertically mounted on the wire feeding frame 510. The telescopic end of the third cylinder 520 is fixedly connected to the upper cutting blade 518. The third cylinder 520 can drive the upper cutting blade 518 to rise and fall. When the upper cutting blade 518 descends to engage with the lower cutting blade 519, it can cut the cable away from its crimped end. Before the cutting mechanism is activated, the cable cutting position can be adjusted by the advancing mechanism of the wire feeding assembly 500, thereby obtaining a cable product of a set length.

[0058] 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 raw materials are intermediate products whose cable ends have been stripped. It should be understood that when implementing this embodiment, an input mechanism must be set at the front end of the wire feeding component 500 to input the stripped intermediate products into the wire feeding component 500 in sequence under automatic control, thereby realizing continuous crimping production.

[0059] 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 feed frame 510 is slidably connected to the frame 100 and can slide longitudinally on the frame 100. The stripping assembly 600 can automatically strip the cable ends. During use, the raw material can be a cable coil. First, the end of the cable to be crimped is inserted into the wire feed frame 510 through an external pulling device and clamped by the wire feed mechanism. The wire feed frame 510 then slides to a position opposite the stripping assembly 600 to complete the stripping of the cable end. The wire feed frame 510 then slides to a position opposite the crimping assembly 200 to complete the crimping operation in the same manner as described above. The cutting mechanism of the wire feed assembly 500 then operates to cut the cable to the set length, and the cable products are then collected. Thus, the addition of the stripping assembly 600 enables fully automated production from stripping to crimping, directly producing crimped cable segments from the cable coil.

[0060] 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 be directly used to 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.

[0061] One set of each of the aforementioned 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 aforementioned manner (automatic crimping production of one end of a multi-core cable can be realized by adding a branching assembly 400). 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 forward and backward conveyance of the cable, when there are two wire feeding frames 510 arranged opposite each other, the cable can be transferred from one wire feeding frame 510 to the other wire feeding frame 510; thus, during implementation, the automatic crimping device can be used in two sets together, with the two sets of automatic crimping devices arranged back to back, and 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.

[0062] When implementing it specifically, 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 a 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 this synchronous belt mechanism is conducive to accurate positioning of the wire feeding frame 510.

[0063] The stripping assembly 600 can be used in a variety of 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 peeling assembly 600 includes a drive mechanism and a peeling mechanism.

[0064] The driving mechanism includes a driving shaft 610, a first transmission shaft 611, an intermediate transmission shaft 612, a second transmission shaft 613, a first transmission belt 614 and a second transmission belt 615. The driving shaft 610, the first transmission shaft 611, the intermediate transmission shaft 612 and the second transmission shaft 613 are all rotatably connected to the frame 100 and are all arranged in the longitudinal direction. 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 provided on the intermediate transmission shaft 612, a transmission gear B617 is fixedly provided on the second transmission shaft 613, and the transmission gear A is engaged with the transmission gear B. A first friction roller 618 is fixedly provided on the first transmission shaft 611, and a second friction roller 619 is fixedly provided on the second transmission shaft 613. During implementation, a peeling motor 601 and a reducer 602 are further provided on the frame 100 . The peeling motor 601 is used to rotate the driving shaft 610 .

[0065] 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 both rotatably connected to the slide 620. The axes of the cutting friction roller 621 and the cutting gear 622 are both parallel to the drive 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 to each other through the 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 surfaces of the upper rack 624 and the tooth surfaces of the lower rack 625 are arranged opposite to each other. The cutting gear 622 is meshed with both the upper rack 624 and the lower rack 625. The slide 620 is slidably connected to the frame 100. The slide 620 slides horizontally on the frame 100 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 mounted 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 mounted on the crank shaft 628. The half gear 630 is fixedly mounted on the drive shaft 610 and meshes with the sliding gear 629. In a specific embodiment, a material receiving box 603 is also fixedly mounted on the slide 620. The material receiving box 603 is used to receive peeled insulating rubber.

[0066] Furthermore, there are two peeling mechanisms in the peeling assembly 600. The two peeling mechanisms are arranged side by side in a direction parallel to the driving shaft 610, and the phase difference between the two half gears 630 is 180 degrees. The upper rack 624 and the lower rack 625 of one peeling mechanism are respectively fixed with an upper ring cutter 631 and a lower ring cutter 632, and the assembly is formed. Figure 12 、 Figure 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 Figure 14 、 Figure 15 The circular cutting mechanism shown. The bottom end of the upper circular cutting knife 631 and the top end of the lower circular cutting knife 632 are respectively provided with mutually compatible arc-shaped cutting edges for stripping the outer insulating rubber of multi-core cables; the bottom end of the upper bevel cutting knife 633 and the top end of the lower bevel cutting knife 634 are respectively provided with mutually compatible inclined cutting edges for stripping the insulating rubber of each core wire in the multi-core cable.

[0067] The specific structural principle of the stripping assembly 600 and its coordinated operation with the wire feeding assembly 500 to achieve continuous automatic stripping of cable ends or core wire ends are detailed in the Chinese invention patent application "Automatic Stripping Device for Multi-core Cable Ends for Wind Turbine Generators" (Application No.: 202411443688.0), which will not be elaborated here. Because the wire feeding frame 510 in the wire feeding assembly 500 can slide longitudinally, it can automatically switch positions between the stripping assembly 600, the crimping assembly 200, and the collection area after cutting under automatic control. As mentioned above, the crimping assembly 200, the terminal conveying assembly 300, and the wire feeding assembly 500 cooperate to achieve automatic crimping of the ends of single-core cables. The addition of the branching assembly 400 can achieve automatic crimping of the ends of each core wire in a multi-core cable. As a result, the entire device can achieve full-process automated continuous production of cable ends 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 branching 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.

[0068] 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 the core wires and then crimp them separately during the crimping process, the process time of the crimping process is relatively long. 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 with each 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 automatic crimping mechanisms is in the crimping process, the other set of automatic crimping mechanisms is in the stripping process. This can better achieve process connection and improve production efficiency.
