Description

Technical Field

[0001] The present invention relates to the technical field of wire stripping machines, in particular to a wire peeling machine. Background Art

[0002] A wire stripping machine is a machine that separates the outer sheath of a cable from its inner metal core. Existing wire stripping machines typically consist of a wire feed mechanism and a wire outlet mechanism, with a wire cutting device located between them. These three mechanisms work together to perform operations such as cutting and stripping the cable.

[0003] Existing wire peeling machines typically use pneumatic cylinders to control two or four upper and lower blades to separate the wire sheath. However, during the separation process, especially when the wire sheath is intermittently separated, the wire can easily shift due to inadequate clamping and fixation. This can cause the upper and lower cutting edges to misalign, ultimately resulting in incomplete and incomplete sheath separation. Furthermore, because the pneumatic cylinder controls the blades, the cutting depth is also imprecise, significantly affecting the quality and stability of the wire stripping. Furthermore, the middle sheath is also held in place by a pair of blades, and peeled off by the pull of a wheel, resulting in less than ideal results.

[0004] Therefore, it is necessary to design a wire peeling machine to greatly improve the accuracy and stability of the wire stripping process, thereby improving the efficiency and quality of wire stripping. Summary of the Invention

[0005] In response to the above technical problems, the present invention provides a wire peeling machine. When in use, a marking mechanism, a conveying mechanism and a peeling mechanism are set up to realize mechanical automation from the division of the middle outer skin of the wire to the peeling, and finally cutting according to the set length, thereby improving the efficiency of wire stripping. More importantly, a motor is set on each mechanism to control the action, which can accurately control the depth and position of the blade entering the outer skin, greatly improving the peeling quality and stability of the middle outer skin of the wire.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A wire stripping machine, characterized in that it comprises a chassis, a panel is provided on the front side of the chassis, a marking mechanism, a conveying mechanism and a peeling mechanism are sequentially provided on the panel, the marking mechanism is used to split the outer skin of the wire, the conveying mechanism is used to convey the split wire, and the peeling mechanism is used to peel the middle outer skin of the wire from the conveying mechanism;

[0008] The marking mechanism includes a first lifting motor and a marking motor, the first lifting motor is connected to the lifting mechanism, the lifting mechanism is provided with a first lifting screw, the first lifting screw is symmetrically provided with an upper wire guard clamp and a lower wire guard clamp, the upper wire guard clamp and the lower wire guard clamp are both equipped with built-in cutting tools, the cutting tools are arranged oppositely and collinearly and are respectively connected to the marking motor, and the marking motor is used to drive the cutting tools in the upper wire guard clamp and the lower wire guard clamp to move back and forth.

[0009] By adopting the above technical solution, it can be ensured that when stripping the wire, the upper wire guard clamp and the lower wire guard clamp are first clamped and fixed by the first lifting motor on the marking mechanism in cooperation with the first lifting screw to prevent displacement during segmentation, resulting in incomplete segmentation dislocation. Then, the marking motor is used to control the tool built into the upper wire guard clamp and the lower wire guard clamp to score from one end of the wire to the other end to achieve the segmentation of the outer skin. During the segmentation, the marking motor reciprocates back and forth so that the wire can continuously enter the upper wire guard clamp and the lower wire guard clamp for segmentation. Since the tools in the upper wire guard clamp and the lower wire guard clamp are relatively and collinearly set, that is, the blade of the tool is facing the blade, it can be ensured that the upper and lower segmentation openings are also in the same plane, thereby avoiding the occurrence of segmentation dislocation and improving accuracy. At the same time, the marking motor is used to control the depth of the tool entering the outer skin to always remain consistent, thereby improving the quality and stability of wire stripping.

[0010] Furthermore, the conveying mechanism is provided with a second lifting motor, the output end of the second lifting motor is provided with a gear, the gear is meshed with a first tooth plate and a second tooth plate, and the first tooth plate and the second tooth plate move toward each other under the drive of the gear.

[0011] By adopting the above technical solution, it can be ensured that the second lifting motor is used to drive the gear to rotate, and the gear will move the meshed first tooth plate and the second tooth plate toward each other, and then the synchronous pulley groups on each gear box can be controlled to achieve changes in the spacing. By using the second lifting motor, the pressure and transmission speed of the synchronous pulley group on the wire can be stably and accurately controlled. At the same time, a single motor can also be used to stably control the change in the distance between the upper and lower gear boxes, greatly reducing the cost of the overall equipment and structural optimization.

[0012] Furthermore, the first tooth plate and the second tooth plate are respectively provided with a gear box, the gear box is equipped with a synchronous pulley set, the synchronous pulley set is equipped with a synchronous belt, and a conveying motor is provided at one end of the synchronous pulley set, and the conveying motor is used to provide conveying power to the conveying mechanism.

[0013] By adopting the above technical solution, it can be ensured that the first tooth plate and the second tooth plate are used to connect their respective gear boxes, and the first tooth plate and the second tooth plate are controlled by the second lifting motor to move toward each other to achieve the change of the distance between the upper and lower gear boxes. The gear box can be used to install the synchronous pulley group on it, and the conveying motor can be used to provide conveying power for the synchronous pulley group. When conveying wire, a synchronous belt is installed on the synchronous pulley group and conveyed by the conveying motor.

[0014] Furthermore, the peeling mechanism is provided with a third lifting motor, the third lifting motor is provided with a second lifting screw, the second lifting screw is provided with two bearing seats, the two bearing seats are respectively provided with a blade mounting block, and one end of the blade mounting block is provided with a cutting blade and a peeling device.

[0015] By adopting the above technical solution, it can be ensured that the third lifting motor and the second lifting screw can be used to control the two bearing seats to move closer or farther away from each other, and then the two bearing seats are used to drive the blade mounting blocks equipped with cutting blades to move closer or farther away from each other to cut the wire that has been peeled off.

[0016] Furthermore, the stripping device is provided with a fixed frame, and two stripping blades are arranged opposite to each other in the fixed frame.

[0017] By adopting the above technical solution, it can be ensured that the separated outer sheets are squeezed and peeled off by using the two oppositely arranged stripping blades to move closer to each other, thereby completing the complete separation of the wire sheath from the metal wire.

[0018] Furthermore, a telescopic motor is provided at one end of the blade mounting block away from the cutting blade.

[0019] By adopting the above technical solution, it can be ensured that the stripping blade and the cutting blade can be switched by using the telescopic motor. During operation, the stripping blade is first used to strip the already separated outer skin, and then the telescopic motor is extended to place the wire between the cutting blades for cutting.

[0020] Furthermore, the peeling mechanism is provided with a separation mechanism, and the separation mechanism is provided with a slide cylinder, a guide plate is horizontally provided below the slide cylinder, an eight-shaped guide groove is provided through one end of the guide plate, and the lower part of the guide plate is connected to a separation plate through the guide groove, a guide rod is provided between the separation plates, and a slide is provided at one end of the separation plate away from the guide rod, and blocks are provided on both sides of the slide.

[0021] By adopting the above technical solution, it can be ensured that the slide cylinder drives the separation plates to move closer and separate from each other along the eight-shaped guide groove, and then the slide under the separation plate slides along the blocks on both sides. The blocks serve as a limit for the slide, and the sliding of the slide drives the two sets of opposing stripping blades to move towards each other, thereby realizing the extrusion and separation of the outer skin. At the same time, the guide rod between the separation plates is used to realize the linkage of the upper and lower stripping blades. While the two blade mounting blocks separate and move closer in the vertical direction, the extrusion and separation of the stripping blades is also realized.

[0022] Furthermore, a wire feeding mechanism is provided between the conveying mechanism and the peeling mechanism, the wire feeding mechanism is provided with a base plate, a slide rail is provided on the base plate, a slider is provided on the slide rail, a guide tube frame is provided on the slider, and the lower end of the slider is connected to a wire feeding cylinder.

[0023] By adopting the above technical solution, it can be ensured that the wire-entry cylinder can improve the guiding performance of the wire, improve the rigidity of the wire itself, and can quickly and accurately enter the wire into the conduit.

[0024] Furthermore, the upper wire protection clamp and the lower wire protection clamp are both provided with wire protection clamp fingers and a fixing portion. The wire protection clamp fingers are V-shaped as a whole and long holes are provided between the wire protection clamp fingers along the length direction of the fixing portion. The wire protection clamp fingers of the upper wire protection clamp and the lower wire protection clamp are arranged crosswise.

[0025] By adopting the above technical solution, it can be ensured that the wire between the upper wire guard clamp and the lower wire guard clamp can be firmly fixed by utilizing the V-shaped wire guard clamp finger structure and the cross arrangement, thereby avoiding the position displacement of the wire during cutting and the incomplete cutting dislocation. At the same time, the long hole is utilized to provide path guidance for the tool under the drive of the marking motor, thereby improving the stability of the tool during cutting.

[0026] Furthermore, the first tooth plate and the second tooth plate are symmetrically arranged and are both provided with a connecting portion and a rack portion, and the rack portion is arranged at an end portion of one side of the connecting block.

[0027] By adopting the above technical solution, it can be ensured that the connecting part can be connected to the gear box, and the rack part can be engaged with the gear on the second lift to drive the change of the distance between the gear box and the synchronous pulley set.

[0028] In summary, the beneficial technical effects of the present invention are:

[0029] (1) The first lifting motor on the marking mechanism cooperates with the first lifting screw to clamp the upper wire guard clamp and the lower wire guard clamp to fix the wire material, so as to prevent displacement during segmentation, resulting in incomplete segmentation. Then, the marking motor is used to control the tool built into the upper wire guard clamp and the lower wire guard clamp to score from one end of the wire material to the other end to achieve the segmentation of the outer skin. During the segmentation, the marking motor reciprocates back and forth so that the wire material in the upper wire guard clamp and the lower wire guard clamp can be continuously entered for segmentation. Since the tools in the upper wire guard clamp and the lower wire guard clamp are relatively and collinearly arranged, that is, the blades of the tools are facing the blades, it can be ensured that the upper and lower segmentation ports are also in the same plane, thereby avoiding the occurrence of segmentation dislocation and improving the accuracy. At the same time, the marking motor is used to control the tool so that the depth of the tool entering the outer skin is always consistent, thereby improving the quality and stability of wire stripping.

[0030] (2) The V-shaped wire protection clamp finger structure can be used for wires of different diameters, without the need to adapt different conduits according to the wire diameter. At the same time, when splitting, the wire is first surrounded and protected and then split, which improves the stability and accuracy of the splitting.

[0031] (3) The use of the first tooth plate and the second tooth plate not only adjusts the spacing between the gear boxes, but also simplifies the structure and reduces the overall cost in conjunction with the second lifting motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention will be described clearly and completely below with reference to the embodiments.

[0052] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention.

[0054] See attached Figure 1-2 , a wire peeling machine is shown, including a chassis 1, a panel 2 is vertically provided on the front side of the chassis 1, and a marking mechanism 3, a conveying mechanism 4, a wire feeding mechanism 6, a peeling mechanism 5 and a conveying mechanism 4 are provided on the panel 2 from left to right. The marking mechanism 3 is used to cut the outer skin 59 of the wire entering between the upper wire guard clamp 10 and the lower wire guard clamp 11, and the conveying mechanism 4 is used to convey the wire to the next workstation. The wire feeding mechanism 6 is used to increase the guiding property of the wire to facilitate its introduction into the guide tube 45, and the peeling mechanism 5 is used to peel off the outer skin 59 of the wire from the marking mechanism 3. A guide tube seat 52 is fixedly provided on the panel 2, and a guide tube 45 is provided on the guide tube seat 52. The guide tube 45 is located between the marking mechanism 3, the conveying mechanism 4 and the peeling mechanism 5. The guide tube 45 is used to enhance the guiding property and protection of the wire and facilitate entry into each mechanism;

[0055] See attached Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 14 , Attachment Figure 15As shown, the marking mechanism 3 is provided with a rear plate 53, the rear plate 53 is bolted to one side of the panel 2, the bottom of the rear plate 53 is vertically provided with a side plate 54, one end of the side plate 54 is provided with a connecting plate 55, the connecting plate 55 is provided with a marking motor 8, the marking motor 8 is used to provide a driving force for the marking operation, the bottom of the rear plate 53 is provided with a first lifting motor 7, the output end of the first lifting motor 7 is provided with a step pulley, the step pulley is linked to the step pulley at the other end of the rear plate 53 through a synchronous belt, the step pulley at the other end of the rear plate 53 is provided with a first lifting screw 9, the first Two bearing seats 22 with opposite threads are provided on the lifting screw 9. Two tool clamps 48 are respectively provided on the ends of the two bearing seats 22 away from the first lifting screw 9. Each tool clamp 48 is provided with a tool guide rail 47. A tool fixing block 46 is provided on the tool guide rail 47. The tool fixing block 46 and the tool guide rail 47 slide with each other through a slider 37. Two screw fixing blocks 51 are symmetrically provided at one end of the tool 12 fixing block. A screw nut is provided between the two screw fixing blocks 51. The screw nut is connected to the marking motor 8 through a screw.

[0056] The front end of the tool holder 48 is provided with a mounting square hole, in which an upper wire guard clip 10 and a lower wire guard clip 11 are provided. The tool holder 48 is provided with a side plate 54 at one end of the mounting square hole, and an upper cover plate 49 is provided on the upper portion of the mounting square hole. The upper cover plate 49 has a long hole along the length direction. Figure 14 The upper and lower wire guard clamps 10 and 11 are both provided with a fixing portion 41 and a wire guard finger 40. The fixing portion 41 is used to be placed in the mounting square hole of the tool clamp seat 48 for fixing. The fixing portion 41 is provided with an elongated hole 42 along the height direction. The elongated hole 42 is used for the movement and limitation of the tool 12, thereby improving the marking accuracy of the tool 12. At the same time, the wire guard finger 40 is arranged in a V-shape, and the wire guard fingers 40 of the upper and lower wire guard clamps 10 and 11 are arranged crosswise, so that the wire can be firmly fixed during cutting, thereby preventing the wire from being offset and causing cutting misalignment. The elongated holes 42 of the upper and lower wire guard clamps 10 and 11 are respectively provided with knives 12, and the two knives 12 are in a collinear relationship, and the directions of the blades are the same. In this way, when moving in the elongated hole 42, the cutting accuracy of the wire sheath 59 can be greatly improved, ensuring that the sheath 59 is cut thoroughly, and the shank portion of the tool 12 is fixed to the tool fixing block 46 through the elongated hole of the upper cover plate 49;

[0057] Not only that Figure 14 The cutting portion of the tool 12 shown, i.e. the tip portion, is higher than the lowest point of the wire guard clamp finger 40. In this way, when the upper wire guard clamp 10 and the lower wire guard clamp 11 clamp the wire, the cutting portion of the tool 12 will be inserted into the wire sheath 59, ensuring that the sheath 59 is cut through.

[0058] When the marking mechanism is working, it first uses the first lifting motor 7 to separate the two bearing seats 22 on the first lifting screw 9 through the step pulley and the synchronous belt linkage. Replacing the cylinder with a motor can not only improve efficiency, but the most important thing is that the motor control accuracy is high. The separation of the two bearing seats 22 drives the tool 12 clamp seat, the upper wire guard clamp 10 and the lower wire guard clamp 11 connected thereto to separate. At this time, the wire to be peeled is placed between the upper wire guard clamp 10 and the lower wire guard clamp 11, and then the first lifting motor 7 is used to reverse the first lifting screw 9 to The upper wire guard clamp 10 and the lower wire guard clamp 11 approach each other. When the set approach distance is reached, the two collinear tools 12 both enter the outer skin 59. Then the marking motor 8 is started. Through the cooperation of the lead screw and the lead screw nut, the lead screw nut will pull the lead screw fixing block 51 set on the left and right sides to move from right to left. At this time, the lead screw fixing block 51 will link the tool fixing block 46 and the guide rod 32 to drive the tool 12 along the long hole of the upper cover plate 49 and the long strip hole 42 of the upper wire guard clamp 10 and the lower wire guard clamp 11, thereby realizing the segmentation of the wire outer skin 59.

[0059] It should be noted that in order to ensure that the marking motor 8 moves the tool 12 when the upper wire guard clamp 10 and the lower wire guard clamp 11 are separated and approached, the two screw fixing blocks 51 set on the tool 12 fixing block will slide along the circular screw nut.

[0060] It should be noted that the first lifting screw 9 and the second lifting screw 21 are composed of two parts with symmetrical threads, and can separate and approach the two bearing seats 22 when rotating.

[0061] See attached Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 16 , the conveying mechanism 4 is provided with a fixed plate, which is fixed to one side of the panel 2, and a vertical plate 56 is vertically provided at the bottom of the fixed plate, and a second lifting motor 13 is provided on the vertical plate 56, and a gear 14 is provided at the output end of the second lifting motor 13, and a first gear plate 15 and a second gear plate 16 are provided on the left and right sides of the gear 14 respectively. The first gear plate 15 and the second gear plate 16 have the same structure and are symmetrically arranged on both sides of the gear 14, as shown. Figure 16The first tooth plate 15 and the second tooth plate 16 are both provided with a connecting portion 43 and a rack portion 44. The rack portion 44 is used to mesh with the gear 14. Under the rotation of the gear 14, the first tooth plate 15 and the second tooth plate 16 are driven to move closer to or away from each other. A pad is connected to the side of the connecting portion 43 close to the vertical plate 56. Driven by the gear 14, the first tooth plate 15 and the second tooth plate 16 can slide up and down relative to the pad. A gear box 17 is provided on the other side of the connecting portion 43 of the first tooth plate 15 and the second tooth plate 16. The same number of synchronous pulley groups 18 are provided on the two gear boxes 17. The synchronous pulley groups 18 are divided into a driven wheel and a driving wheel. The driving wheel is connected to the conveying motor 19 through a transmission shaft. The conveying motor 19 is located on the same side of the second lifting motor 13 as shown in FIG. Figure 3 As shown;

[0062] When the conveying mechanism 4 is working, a synchronous belt is installed on the upper and lower synchronous pulley groups 18, and the second lifting motor 13 is started to drive the gear 14 to rotate. The gear 14 moves the first tooth plate 15 and the second tooth plate 16 meshed on the left and right sides away from each other, so that the distance between the synchronous pulley groups 18 on the two gear boxes 17 is increased, and the wire is placed between the upper and lower synchronous pulley groups 18. Then the second lifting motor 13 is controlled to reverse and the distance between the first tooth plate 15 and the second tooth plate 16 is reduced until the synchronous belt is close to the wire sheath 59. Then the conveying motor 19 is started to use the driving wheel to drive the entire synchronous pulley group 18 to rotate. At this time, the friction force of the synchronous belt on the wire sheath 59 is used to generate a forward pulling force, which also enhances the rigidity of the wire entering the marking mechanism 3 and facilitates the forward transmission of the wire.

[0063] See attached Figure 9-12 As shown, the peeling mechanism 5 is provided with a rear plate 53, and a third lifting motor 20 is provided at the bottom of the rear plate 53. The output end of the third lifting motor 20 is provided with a synchronous pulley, and the synchronous pulley is linked to the second lifting screw 21 at the other end of the rear plate 53 through a synchronous belt. The second lifting screw 21 is also provided with two bearing seats 22 with opposite thread directions. When the second lifting screw 21 rotates, the distance between the two bearing seats 22 will be increased and decreased. A tool holder seat is connected to the two bearing seats 22, and a blade mounting block 23 is provided slidingly in the tool holder seat. The blade mounting block 23 is provided with a telescopic motor 27 at one end close to the third lifting motor 20. The telescopic motor 27 is fixed on the vertical plate 56 perpendicular to the rear plate 53. The telescopic motor 27 drives the blade mounting block 23 to extend and retract back and forth through the screw at the output end. See the attached Figure 17As shown, two cutting blades 24 are symmetrically provided at one end of the blade mounting block 23 away from the telescopic motor 27. When cutting the wire, the third lifting motor 20 is used to control the two cutting blades 24 to separate and approach via the second lifting screw 21 to cut the outer skin 59 and peel the two ends. A fixed frame 25 is provided at the end of the blade mounting block 23. Two stripping blades 26 are provided in parallel within the fixed frame 25. The stripping blades 26 are used to clamp and cut the wire at the front and rear ends after the outer skin 59 has been separated, and then squeeze and separate the outer skin.

[0064] The left and right ends of the fixed frame 25 are provided with clamping blocks 34, and two sliding seats 33 are provided between the two clamping blocks 34. Figure 12 , the two slides 33 can slide between the two blocks 34, and a separation plate 31 is provided on the top of each slide 33, and a guide rod 32 is provided on the end of the separation plate 31 away from the slide 33. The guide rod 32 is used to link the upper and lower sets of stripping blades 26, and a guide plate 29 is provided on the top of the separation plate 31. The guide plate 29 is provided with an eight-shaped guide groove 30 at one end close to the separation plate 31. A slide cylinder 28 is provided above the guide plate 29, and a linkage bottom plate is provided at the bottom of the slide cylinder 28. The linkage bottom plate is a component on the slide cylinder. The linkage bottom plate is connected to the telescopic end of the slide cylinder 28. A guide column is provided between the linkage bottom plate and the separation plate 31. When the telescopic end of the slide cylinder 28 is extended or retracted, the linkage bottom plate will be used to drive the guide column to slide along the guide groove 30;

[0065] When the peeling mechanism 5 is working, the third lifting motor 20 is first started. The third lifting motor 20 will drive the second lifting screw 21 through the step pulley to separate the upper and lower bearing seats 22 and the tool holder seat and the blade mounting block 23. Then the wire from the conveying mechanism 4 will enter between the upper and lower sets of stripping blades 26. Then, the third lifting motor 20 is reversed to clamp the upper and lower sets of stripping blades 26, that is, four blades, two by two, on the two ends of the wire skin that has been cut open. As the clamping force of the third lifting motor 20 increases, the four stripping blades 26 will cut off the wire skin 59. Then, the telescopic end of the slide cylinder 28 is retracted. At this time, the linkage bottom plate will drive the guide column to The four upper and lower separation plates 31 are brought close to each other. The close proximity of the separation plates 31 will act on the slide 33 to drive the stripping blades 26 to approach each other. At this time, the four stripping blades 26 will squeeze the cut wire sheath 59 from both ends to the middle. Since the wire sheath 59 at this time has been divided by the scribing mechanism 3, it will be separated from the wire metal wire and fall off under the squeezing of the stripping blades 26, thus achieving peeling; after the wire is peeled, the telescopic motor 27 is used to act on the tool 12 mounting block and the cutting blade 24 to extend. At this time, the peeled wire is located between the two cutting blades 24, and then the third lifting motor 20 is used to control the cutting blade 24 to achieve cutting.

[0066] It should be noted that in order to prevent the wire from bending when peeling with the stripping blade 26, a conveying mechanism 4 is also provided on the right side of the peeling mechanism 5. When peeling the wire, the conveying mechanisms 4 on both sides of the peeling mechanism 5 are used to frictionally tighten the two ends of the wire, thereby increasing the rigidity of the wire.

[0067] See attached Figure 13 As shown, in order to facilitate the entry of the wire into the peeling station, an entry mechanism 6 is added between the conveying mechanism 4 and the peeling mechanism 5. The entry mechanism 6 is provided with a base plate 35, and the base plate 35 is fixed on the panel 2. A slide rail 36 is provided on the base plate 35, and a slider 37 is provided on the slide rail 36. The bottom of the slider 37 is provided with an entry cylinder 39, and a guide tube frame 38 is provided on one side of the slider 37. A guide tube 45 is provided in the guide tube frame 38. After the wire is cut by the cutting blade 24, in order to guide the wire end into the end conveying mechanism 4, the entry cylinder 39 is used to slide the guide tube 45 forward. Due to the presence of the guide tube 45, the guiding property of the wire is enhanced. After the wire is fed into the end conveying mechanism 4, the entry cylinder 39 retracts the guide tube 45 to avoid interference with the next peeling and cutting.

[0068] In order to better improve the working efficiency, accuracy and consistency of each mechanism, sensors 57 and induction sheets 58 are set on the marking mechanism 3, the conveying mechanism 4 and the peeling mechanism 5. The sensor 57 and induction sheet 58 on the marking mechanism 3 can control the separation distance between the upper wire guard clamp 10 and the lower wire guard clamp 11 and the clamping force on the wire; the sensor 57 and induction sheet 58 on the conveying mechanism 4 can control the friction between the synchronous belt and the wire outer skin 59 to ensure the normal conveying of the wire; the sensor 57 and induction sheet 58 on the peeling mechanism 5 can control the cutting force of the stripping blade 26 on the outer skin 59 to prevent the cutting force from being too strong. The outer skin 59 cannot be cut through when the metal wire is cut too much or the cutting force is too small; at the same time, the sensor 57 and the first lifting motor 7, the second lifting motor 13, and the third lifting motor 20 are electrically connected, so that the operation can be performed more accurately and efficiently, which not only improves the efficiency of marking, peeling, and cutting of the wire, but also ensures the quality of the operation. In addition, the V-shaped structure and the long strip hole 42 of the upper wire guard clamp 10 and the lower wire guard clamp 11 are used to improve the fixing quality of the wire during marking, prevent segmentation dislocation, and improve the segmentation accuracy. The working principle of the sensor 57 and the induction plate 58 and the equipment itself are existing technologies, so they will not be repeated here.

[0069] The working principle is as follows: first, the first lifting motor 7 is used to separate the two bearing seats 22 on the first lifting screw 9 through the step pulley and the synchronous belt linkage, and the separation of the two bearing seats 22 drives the tool clamp seat 48, the upper wire guard clamp 10 and the lower wire guard clamp 11 connected thereto to separate, and at the same time, the second lifting motor 13 is started to drive the gear 14 to rotate, and the gear 14 moves the first tooth plate 15 and the second tooth plate 16 meshed on the left and right sides away from each other, so that the distance between the synchronous pulley groups 18 on the two gear boxes 17 is increased, and the wire is placed between the upper and lower synchronous pulley groups 18 and between the upper wire guard clamp 10 and the lower wire guard clamp 11, and then the second lifting motor 13 is controlled to reverse to reduce the distance between the first tooth plate 15 and the second tooth plate 16 to The synchronous belt is pressed against the outer skin 59 of the wire, and then the conveying motor 19 is started to use the driving wheel to drive the entire synchronous pulley group 18 to rotate. At this time, the friction force of the synchronous belt on the outer skin 59 of the wire is used to generate a forward pulling force, and then the first lifting motor 7 is used to reverse the first lifting screw 9 to move the upper wire guard clamp 10 and the lower wire guard clamp 11 closer to each other. When the set approach distance is reached, the two collinear tools 12 both enter the outer skin 59, and then the marking motor 8 is started. Through the cooperation of the screw and the screw nut, the screw nut will pull the screw fixing block 51 set on the left and right sides to move from right to left. At this time, the screw fixing block 51 will link the tool fixing block 46 and the guide rod 32 to drive the tool 12 along the long hole of the upper cover plate 49 and the upper wire guard clamp 10 and the long strip hole 42 of the lower wire guard clamp 11 move, thereby realizing the segmentation of the wire sheath 59, and then the conveying mechanism 4 is used to continue to convey the already segmented wire forward, and when it reaches the peeling mechanism 5, the third lifting motor 20 is started, and the third lifting motor 20 drives the second lifting screw 21 through the step pulley to separate the upper and lower bearing seats 22 and the tool holder seat and the blade mounting block 23, and then the wire from the conveying mechanism 4 will enter between the upper and lower stripping blades 26, and then the third lifting motor 20 is used to reverse and clamp the upper and lower stripping blades 26, that is, the four blades, two by two, at both ends of the wire, and as the clamping force of the third lifting motor 20 increases, the four stripping blades 26 will cut off the wire sheath 59, and then use When the telescopic end of the slide cylinder 28 is retracted, the linkage base plate 35 will drive the guide column to make the upper and lower four separation plates 31 move closer together. The moving closer of the separation plates 31 will act on the slide 33 to drive the stripping blades 26 to move closer to each other. At this time, the four stripping blades 26 will squeeze the cut wire skin 59 from both ends to the middle. Since the wire skin 59 has been divided by the scribing mechanism 3 at this time, it will be separated from the wire metal conductor and fall off under the squeezing of the stripping blades 26, thus achieving peeling; after the wire is peeled, the telescopic motor 27 is used to act on the tool 12 mounting block and the cutting blade 24 to extend. At this time, the peeled wire is located between the two cutting blades 24, and then the third lifting motor 20 is used to control the cutting blade 24 to achieve cutting.

[0070] It should be noted that, see the attached Figure 18The figure shows the effect of the present invention on the peeling of the wire. It can be seen that the present invention can not only peel the outer skin of the wire in the middle, that is, intermittent peeling, but also peel both ends of the wire.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
