[0027] See also Figures 1 to 7 , is a multifunctional wire stripping machine according to an embodiment of the present invention, which is used to strip the wires 90 to be processed. Figure 6 and Figure 7 As shown, it includes an insulator 91 and a conductor 92. The multifunctional wire stripping machine includes a base 10, a wire stripping mechanism 20 mounted on the base 10, and a wire unwinding drive mechanism 30 for driving the wire stripping mechanism 20 to move forward and backward. The wire stripping mechanism 20 includes a wire stripping bracket 21 mounted on the wire unwinding drive mechanism 30, a wire stripping assembly 22 mounted on the wire stripping bracket 21, a wire stripping driver 23 for driving the wire stripping assembly 22, and a contact sensor 24 mounted on the wire stripping assembly 22 for sensing the cable 90.

[0028] The working principle of the multifunctional wire stripping machine of the present invention is as follows: when the cable 90 to be processed is placed on the contact sensing member 24 of the wire stripping mechanism 20, the wire stripping mechanism 20 senses the cable 90 to be processed through the contact sensing member 24, starts the wire stripping driver 23 to drive the wire stripping assembly 22 to move, and shears the insulator 91 of the cable 90; after the shearing of the insulator 91 is completed, the wire retracting drive mechanism 30 drives the wire stripping mechanism 20 to move backward; the insulator 91 to be cut off is gradually separated from the cable 90.

[0029] Compared with the prior art, the multifunctional wire stripping machine of the present invention can quickly and accurately complete the shearing and separation of the insulator 91 when the cable 90 touches the contact sensing element 24 through the coordinated work of the wire stripping assembly 22 and the wire retraction drive mechanism 30, thereby effectively improving work efficiency; there is no need to manually adjust the position of the cable 90 or judge the timing of wire stripping, only need to put the cable 90 into the specified position, and the wire stripping machine can automatically complete the wire stripping operation, reducing the work intensity and technical requirements of the operator; the automated wire retraction drive mechanism 30 can automatically separate the cut insulator 91 from the cable 90, making the entire wire stripping process smoother and more convenient; the wire stripping assembly 22, under the control of the wire stripping driver 23, can accurately shear the insulator 91 of the cable 90, ensuring a neat incision without damaging the internal conductor, thereby improving the quality of wire stripping.

[0030] In this embodiment, the multifunctional wire stripping machine also includes a control system. By inputting a PLC control program into the control system, the size of the cable 90 to be cut and the number of cuts are set in the program; for example, if ten cuts are required, the first five cuts are for a 1.7 cm cable 90, and the insulator 91 to be cut is 0.5 cm. The last five cuts are for a 1.3 cm cable 90, and the insulator 91 to be cut is 0.4 cm. The PLC control program can accurately set the cutting parameters for different cable 90 sizes. Whether it is a 1.7 cm or 1.3 cm cable 90, it can be accurately cut according to the set thickness of the insulator 91, ensuring the accuracy and consistency of each wire stripping, and meeting various specific processing requirements. The user only needs to input the PLC control program into the control system to complete the complex wire stripping task settings, without the need for tedious mechanical adjustments. The operation is simple and convenient, and the requirements for the operator's technical level are reduced.

[0031] See also Figure 2 、 Figure 4 and Figure 5The wire stripping assembly 22 includes a first drive member 220 mounted on a wire stripping driver 23, two wire stripping arms 221 movably mounted on a wire stripping bracket 21, and wire stripping blades 222 mounted on mating surfaces of the wire stripping arms 221. The wire stripping driver 23 is used to drive the first drive member 220 back and forth toward the cable 90 to be processed. The wire stripping assembly 222 also includes rollers 223 mounted on the free ends of the wire stripping arms 221. The tapered ends of the first drive member 220 contact and engage the rollers 223 on the two wire stripping arms 221. The first drive member 220 has driving surfaces 228 on either side that are inclined toward the extension direction of the cable 90 to be processed. The distance between each driving surface 228 and the centerline axis of the first drive member 220 increases gradually from the end closest to the wire stripping blades 222 toward the end farther from the wire stripping blades 222. When the cable 90 is placed on the contact sensing component, the contact sensing member 24 senses the signal, and the wire stripping driver 23 drives the first driving member 220 to move back and forth toward the cable 90 to be processed; the tapered end of the first driving member 220 contacts and connects with the rollers 223 on the two stripping arms 221; since the driving surfaces 228 on both sides of the first driving member 220 are inclined to the extension direction of the cable 90 to be processed, and the distance between each driving surface 228 and the central axis of the first driving member 220 gradually increases from the end close to the stripping blade 222 to the end away from the stripping blade 222; as the first driving member 220 moves forward, its driving surface 228 pushes the roller 223, so that the two stripping arms 221 begin to close relative to each other; the stripping arms 221 are at the first driving member 22 0, the stripping blade 222 installed on the mating surface of the stripping arm 221 will gradually approach the cable 90; when the stripping arm 221 is closed to a certain extent, the stripping blade 222 cuts into the outer sheath of the cable 90; as the stripping arm 221 continues to close, the stripping blade 222 will cut the outer sheath of the cable 90 along the circumferential direction of the cable 90 and split the outer sheath; because of the contact method between the roller 223 and the first driving member 220 and the special shape of the driving surface 228, it can ensure that the stripping arm 221 has appropriate force and angle to complete the stripping action during the closing process, making the stripping process more stable and accurate; when the stripping blade 222 completes cutting the outer sheath of the cable 90, it cooperates with the wire-retracting driving mechanism 30 to remove the insulator 91 to achieve wire stripping of the cable 90.

[0032] The wire stripping assembly 22 also includes a positioning post 224 and a movable post 225. The roller 223 is mounted on the wire stripping arm 221 via the positioning post 224, and the wire stripping arm 221 is movably mounted on the wire stripping bracket 21 via the movable post 225. The roller 223 is mounted on the wire stripping arm 221 via the positioning post 224, which precisely fixes the position of the roller 223. When the wire stripping driver 23 drives the first driving member 220 to move, the tapered end of the push rod contacts the roller 223. Due to the fixed positioning post 224, the roller 223 can only rotate about the axis of the positioning post 224 or move within the small displacement range allowed by the positioning post 224. This ensures that the contact relationship between the roller 223 and the first driving member 220 is stable and predictable during the opening and closing of the wire stripping arm 221. The wire stripping arm 221 is movably mounted on the wire stripping bracket 21 through the movable column 225. The movable column 225 is the key component that enables the wire stripping arm 221 to open and close; the movable column 225 allows the wire stripping arm 221 to rotate around its axis, thereby realizing the opening and closing action of the wire stripping arm 221; when the first driving member 220 moves forward to squeeze the roller 223, the roller 223 will be subjected to an outward force, and this force is transmitted to the movable column 225 through the wire stripping arm 221; due to the movable installation method of the movable column 225, the wire stripping arm 221 will rotate outward with the movable column 225 as the axis to realize the opening action; and when the first driving member 220 moves backward, the wire stripping arm 221 loses the external force extrusion, and under the action of its own elastic restoring force, it will rotate inward with the movable column 225 as the axis, returning to its original position to realize the closing action.

[0033] The wire stripping bracket 21 includes a first wire stripping frame 210, a second wire stripping frame 211 and a connecting rod 212; the first wire stripping frame 210 is installed on the wire retraction drive mechanism 30, and the second wire stripping frame 211 is installed on the first wire stripping frame 210 through the connecting rod 212; the wire stripping driver 23 is a wire stripping linear motor installed on the first wire stripping frame 210, the wire stripping linear motor is connected to the lead screw, the sliding block 51 is sleeved on the lead screw, and the first driving member 220 is fixed on the sliding block 51. Insertion and sensing of cable 90: When cable 90 is put into the wire stripping machine and touches the contact sensing element 24, the contact sensing element 24 senses the cable 90, and the linear motor drives the screw rod to rotate, causing the sliding block 51 to move forward on the screw rod; as the sliding block 51 moves forward, the first driving member 220 fixed thereon also moves forward; the tapered end of the first driving member 220 gradually inserts into the gap between the two stripping arms 221 facing away from one end of the stripping blade 222, stretching the stripping arms 221 to open the stripping blade 222; after the cable 90 is adjusted to the appropriate position, the stripping linear motor rotates in the opposite direction, driving the screw rod to cause the sliding block 51 to move backward; the first driving member 220 then moves forward After the movement, the stripping arm 221 that has lost its supporting function gradually closes under the action of its own elasticity or other reset mechanism, and the stripping blade 222 approaches the insulator 91 of the cable 90 and cuts it; after completing the cutting of the insulator 91, the wire-retracting drive mechanism 30 is started, driving the first stripping frame 210 to move back and forth, and then driving the entire stripping bracket 21 and the stripping member installed thereon to move back and forth, so that the cut insulator 91 is separated from the cable 90; through the coordinated action of the stripping linear motor, the lead screw, the sliding block 51 and the first driving member 220, precise control of the stripping arm 221 and the stripping blade 222 is achieved, ensuring the efficiency and accuracy of the stripping operation.

[0034] The wire-retracting drive mechanism 30 includes a drive rod 31 connected to the first stripping frame 210. A guide rod 40 is positioned between the first and second stripping frames 210, 211. Initially, the wire stripping assembly 22 is positioned to await insertion of the cable 90. At this point, the wire-retracting drive mechanism 30 is also stationary. When the wire stripping element completes shearing of the insulator 91 of the cable 90, the wire-retracting driving mechanism 30 drives the driving rod 31 to perform a linear motion in the forward and backward directions. Since the driving rod 31 is connected to the first wire stripping frame 210, the movement of the driving rod 31 directly drives the first wire stripping frame 210 to move forward and backward. During the movement of the first wire stripping frame 210, the guide rod 40 ensures that the first wire stripping frame 210 and the second wire stripping frame 211 maintain a stable direction and position during the forward and backward movement to prevent deviation or shaking. At the same time, the guide rod 40 also helps to disperse the force during the movement, making the movement of the entire wire stripping bracket 21 more stable. As the first wire stripping frame 210 moves forward and backward, the wire stripping element installed on the wire stripping bracket 21 also moves accordingly. The cut insulator 91 is gradually separated from the cable 90 under the drive of the wire stripping element, completing the wire-retracting operation. Through the coordinated action of the driving rod 31 and the guide rod 40, the wire-retracting driving mechanism 30 can accurately control the forward and backward movement of the wire stripping bracket 21, thereby achieving smooth separation of the insulator 91 from the cable 90.

[0035] The guide rod 40 includes an inner guide rod 41 and an outer guide rod 42. The outer guide rod 42 is sleeved on the outer guide rod 41. The inner guide rod 41 passes through the first wire stripping frame 210 and the second wire stripping frame 211. The two ends of the outer guide rod 42 respectively abut against the first wire stripping frame 210 and the second wire stripping frame 211. When the wire-retracting drive mechanism 30 starts working and the drive rod 31 drives the first wire stripping frame 210 to move, the two ends of the outer guide rod 42 respectively abut against the first wire stripping frame 210 and the second wire stripping frame 211. The outer guide rod 42 provides a stable support between the first wire stripping frame 210 and the second wire stripping frame 211; prevents the wire stripping frame 21 from shaking or deforming during movement, and ensures the accuracy of the wire stripping operation; the inner guide rod 41 passes through the first wire stripping frame 210 and the second wire stripping frame 211. During the wire-retracting drive process, the inner guide rod 41 provides a guide for the forward and backward movement of the wire stripping frame 21; when the first wire stripping frame 210 moves forward and backward under the action of the drive rod 31, the inner guide rod The guide rod 41 restricts the movement of the first stripping frame 210, forcing it to move only along the axis of the guide inner rod 41. Simultaneously, because the guide inner rod 41 also extends through the second stripping frame 211, the second stripping frame 211, driven by the first stripping frame 210, also moves smoothly along the direction of the guide inner rod 41. During the wire withdrawal process, the force transmitted from the drive rod 31 to the first stripping frame 210 is transmitted to the second stripping frame 211 via the guide rod 40. The combined structure of the guide inner rod 41 and the guide outer rod 42 effectively disperses the force, ensuring a more uniform force distribution throughout the entire stripping frame 21 during movement, reducing localized stress concentration and improving the stability and durability of the device. Through the synergistic action of the guide inner rod 41 and the guide outer rod 42, the guide rod 40 provides stable support and precise guidance for the wire withdrawal movement of the stripping frame 21, ensuring smooth separation of the insulator 91 from the cable 90.

[0036] See also Figure 2 and Figure 3The first wire stripping frame 210 is provided with a guide rail 50 and a sliding block slidably mounted on the guide rail 50, and the sliding block 51 is mounted on the sliding block. The multifunctional wire stripping machine also includes a wire stripping sensor and a wire withdrawal sensor. The wire stripping sensor includes a wire stripping receiving end 61 mounted on the first wire stripping frame 210 on one side of the guide rail 50 and a wire stripping sensor end 62 mounted on the sliding block 51. The wire stripping sensor end 62 cooperates with the wire stripping receiving end 61. When the wire stripping driver 23 pushes the first driving member 220 forward, the wire stripping sensor end 62 disengages from the wire stripping receiving end 61. The wire withdrawal sensor includes a wire withdrawal receiving end 71 mounted on the base 10 and a wire withdrawal sensor end 72 mounted on the first wire stripping frame 210. The wire withdrawal receiving end 71 cooperates with the wire withdrawal sensor end 72. When the wire withdrawal driving mechanism 30 pushes the wire stripping mechanism 20 forward, the wire withdrawal sensor end 72 disengages from the wire withdrawal receiving end 71. When the wire stripping sensing component is working, in the initial state, the wire stripping driver 23 is not started, and the sliding block 51 is located at the initial position on the guide rail 50; at this time, the wire stripping sensing end 62 installed on the sliding block 51 is in a mating state with the wire stripping receiving end 61 installed on the first wire stripping frame 210 on one side of the guide rail 50; the wire stripping driver 23 starts to push the first driving member 220 forward. As the first driving member 220 moves forward, the first driving member 220 fixed on the sliding block 51 drives the sliding block 51 to slide forward on the guide rail 50; in the process of the sliding block 51 sliding forward, the wire stripping sensing end 62 installed on the sliding block 51 gradually separates from the wire stripping receiving end 61; in this process, the wire stripping sensing member separates from the sensing end and the receiving end; if an abnormality occurs during the wire stripping process, such as the wire stripping sensing end 62 fails to normally separate from the wire stripping receiving end 61 or the separation time does not match the preset, when the wire stripping driving mechanism 30 is not started, the wire stripping mechanism 20 is in the initial position; at this time, the wire stripping sensing end 72 installed on the first wire stripping frame 210 and the wire stripping receiving end 7 installed on the base 10 1 is in a mating state; when the wire stripping operation is completed, the wire-retracting driving mechanism 30 starts to push the wire stripping mechanism 20 to move forward. As the wire stripping mechanism 20 moves, the wire-retracting sensing end 72 installed on the first wire stripping frame 210 gradually separates from the wire-retracting receiving end 71 installed on the base 10; the wire-retracting sensing element feeds back the working state of the wire-retracting driving mechanism 30 and the position change of the wire stripping mechanism 20 to the control system through the separation of the sensing end and the receiving end; the function of the wire-retracting sensing element is to monitor whether the action of the wire-retracting driving mechanism 30 is normal and whether the wire-retracting position of the wire stripping mechanism 20 is accurate; if an abnormal situation occurs during the wire-retracting process, it ensures that the insulator 91 and the cable 90 can be separated smoothly, while ensuring the safe operation of the equipment.

[0037] See also Figure 2 and Figure 3The multifunctional wire stripping machine further includes a fixing mechanism, which includes a fixing assembly 80 movably mounted on the base 10 and a fixed drive assembly for driving the fixing assembly 80. The fixing mechanism includes two fixing arms 81, a second drive member 82, and a fixing member 83. The fixing arms 81 are movably mounted on the base 10. The fixing member 83 is mounted on the fixing arm 81 on the side facing away from the wire stripping assembly 22. One end of the second drive member 82 is connected to the fixed drive assembly, and the other end abuts against one end of the two fixing arms 81 facing away from the fixing member 83. In the initial non-working state, the fixed drive assembly is in a stationary state and does not generate driving force; the second drive member 82 is stationary and is only slightly in contact with the end of the two fixed arms 81 opposite to the fixed member 83. At this time, the two fixed arms 81 are in a natural state, and the fixed arms 81 movably mounted on the base 10 do not have any fixing effect on the cable 90, and the fixed member 83 is also away from the cable 90; when the cable 90 is placed in a specific position of the wire stripping machine, the contact sensing member 24 senses the presence of the cable 90, and the fixed drive assembly starts to generate power. In this embodiment, the fixed drive assembly is a cylinder. The power of the fixed driving assembly is transmitted to the second driving member 82, which pushes the second driving member 82 to start moving; as the second driving member 82 moves, its tapered end gradually inserts into the gap between the two fixed arms 81 and the ends of the fixing member 83 that are opposite to each other; due to the characteristics of the tapered structure, the second driving member 82 will gradually open the two fixed arms 81; under the action of the second driving member 82, the two fixed arms 81 take their mounting points on the base 10 as axes and gradually open to both sides; the fixing member 83 installed on the fixed arm 81 on the side away from the wire stripping assembly 22 also opens accordingly, making room for the cable 90 to enter; when the cable 90 is in the appropriate position, The fixed drive assembly moves in the opposite direction, pulling the second drive member 82 to move backward; the two fixed arms 81, which have lost the support effect of the second drive member 82, gradually close under the action of their own elasticity or other reset mechanisms; at this time, the fixing member 83 approaches the cable 90 as the fixed arm 81 closes, and finally clamps the cable 90 tightly with appropriate force to fix the cable 90; the fixing member 83 firmly clamps the cable 90, ensuring that the cable 90 will not move or shake when the stripping assembly 22 shears the insulator 91 and the wire-retracting drive mechanism 30 drives the stripping mechanism 20 to move back and forth, thereby ensuring the accuracy and quality of the wire stripping.

[0038] The wire stripping assembly 22 also includes a protective shell 229 mounted on the second wire stripping frame 211. The wire stripping arm 221 is movably mounted within the protective shell 229 via a movable post 225. The protective shell 229 is mounted on the second wire stripping frame 211 to form a relatively enclosed space. The wire stripping arm 221 moves within the protective shell 229 via the movable post 225, providing physical protection for the wire stripping arm 221. During the wire stripping process, the protective shell 229 prevents accidental collisions with the wire stripping arm 221 and affects the accuracy of the stripping operation. It also prevents the wire stripping arm 221 from being damaged by accidental contact with other components during movement. The wire stripping arm 221 is connected to the protective shell 229 via the movable post 225, which enables the wire stripping arm 221 to flexibly rotate or translate within the protective shell 229. When the tapered end of the first driving member 220 pushes the roller 223 on the wire stripping arm 221, the wire stripping arm 221 moves relative to the movable post 225.

[0039] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
