The existing manual operation method is to use a wire stripping device to cut two marks perpendicular to the cable axis, and then cut a mark along the cable axis, and finally manually strip off the insulation sheath. The manual wire stripping method is relatively complicated, and for safety reasons, it is often necessary to shut down the power supply, which affects the stability of power operation.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1 As shown, this embodiment provides a cable insulation stripping device, including a stripping mechanism 1 and a moving mechanism 2. The stripping mechanism 1 is arranged on the moving mechanism 2. The moving mechanism 2 drives the stripping mechanism 1 to move to cut and strip the cable insulation layer, thereby improving the wire stripping efficiency.

[0046] Specifically, Figure 2As shown, the stripping mechanism 1 includes a circular cutting component 11 and a longitudinal cutting component 12. The circular cutting component 11 is located on one side of the longitudinal cutting component 12. The circular cutting component 11 includes a first circular cutting knife 111 and a second circular cutting knife 112 that are relatively arranged. The first circular cutting knife 111 and the second circular cutting knife 112 can move towards or away from each other to clamp the circumference of the cable 100 and cut the cable insulation layer circumferentially or away from the cable 100; the longitudinal cutting component 12 includes a first longitudinal cutting knife 121 and a second longitudinal cutting knife 122 that are relatively arranged. The first longitudinal cutting knife 121 and the second longitudinal cutting knife 122 can move to the opposite sides of the cable 100 to abut and cut the cable insulation layer to cut the cable insulation layer along the axial direction. The cable insulation layer is cut along the circumferential direction of the cable 100 by the ring cutting component 11. The ring cutting component 11 cuts the cable insulation layer at the first stripping position and the second stripping position of the cable 100 respectively. The specific positions of the first stripping position and the second stripping position can be selected according to actual needs and cutting length. When cutting the cable insulation layer, the ring cutting component 11 first moves to the first stripping position to cut the cable insulation layer circumferentially, and then moves to the second stripping position to cut the cable insulation layer circumferentially, so that the cable insulation layer of the set cutting length can be separated from the metal insulation layer at other positions on the cable 100. Then the first longitudinal cutting knife 121 and the second longitudinal cutting knife 122 of the longitudinal cutting component 12 respectively abut against the opposite sides of the cable 100 and penetrate into the cable insulation layer to cut the cable insulation layer. The longitudinal cutting component 12 moves from the first stripping position to the second stripping position, or from the second stripping position to the first stripping position, so that the cable insulation layer between the first stripping position and the second stripping position is divided into two parts along the axial direction of the cable 100, namely the first part and the second part.

[0047] like Figure 3 As shown, the moving mechanism 2 includes a first moving component 21 and a second moving component 22 which are vertically arranged. The first moving component 21 extends along the axial direction of the cable 100. The stripping mechanism 1 is slidably arranged on the first moving component 21. The first moving component 21 is used to drive the stripping mechanism 1 to move along the axial direction of the cable 100. The first moving component 21 is slidably arranged on the second moving component 22. The second moving component 22 drives the stripping mechanism 1 to move along the direction perpendicular to the axial direction of the cable 100 through the first moving component 21. The moving mechanism 2 is used to drive the stripping mechanism 1 to move along the extension direction of the first moving component 21 and the extension direction of the second moving component 22, so as to realize the circumferential cutting of the first stripping position and the second stripping position respectively, and the axial cutting of the cable insulation layer between the first stripping position and the second stripping position, and can realize the stripping of the cable insulation layer at the same time.

[0048] For example, the first moving assembly 21 extends along the X-axis direction, and the second moving assembly 22 extends along the Y-axis direction. The first moving assembly 21 and the second moving assembly 22 are both slide rails and sliders that cooperate to perform linear motion, and the driving member can be driven by a linear motor. By controlling the number of rotations of the linear motor, the moving distance of the stripping mechanism 1 can be accurately controlled, so that the distance between the first stripping position and the second stripping position can be accurately controlled, thereby achieving accurate control of the stripping length of the cable insulation layer.

[0049] Of course, the slider of the second moving assembly 22 is connected to the slide rail of the first moving assembly 21, so that the slider of the second moving assembly 22 moves along the slide rail of the second moving assembly 22, and can drive the first moving assembly 21 to move along the extension direction of the slide rail of the second moving assembly 22. In this embodiment, the specific structures of the first moving assembly 21 and the second moving assembly 22 are not limited, and they only need to meet the linear movement in the corresponding directions.

[0050] In one embodiment, continue to refer to Figure 2 The peeling mechanism 1 further comprises a second mounting seat 13, a second driving assembly 14 and a third driving assembly 15. The second mounting seat 13 is slidably mounted on the first moving assembly 21. The second driving assembly 14 is connected to the circular cutting assembly 11 and is used to drive the circular cutting assembly 11 to move synchronously in a direction close to or away from each other. The third driving assembly 15 is connected to the longitudinal cutting assembly 12 and is used to drive the longitudinal cutting assembly 12 to move in a direction perpendicular to the first moving assembly 21 and the second moving assembly 22.

[0051] The second mounting seat 13 includes a first side and a second side which are adjacently arranged, the first side is arranged perpendicular to the axis of the first moving assembly 21, the second driving assembly 14 and the cutting assembly 11 are both installed on the first side, the second side is arranged parallel to the axis of the first moving assembly 21, and the third driving assembly 15 and the longitudinal cutting assembly 12 are both installed on the second side. The cutting assembly 11 is arranged perpendicular to the axis of the first moving assembly 21, the first cutting knife 111 and the second cutting knife 112 are symmetrically arranged on opposite sides of the axis of the first moving assembly 21, the second driving assembly 14 drives the first cutting knife 111 and the second cutting knife 112 to move in a direction close to each other at the same time, and the first cutting knife 111 and the second cutting knife 112 can clamp the cable 100 in the circumferential direction to achieve circumferential cutting. The longitudinal cutting component 12 is arranged parallel to the axis of the first movable component 21, and the projections of the first longitudinal cutting knife 121 and the second longitudinal cutting knife 122 are both located on the axis of the first movable component 21. The projection of the axis of the cable 100 is also located on the axis of the first movable component 21. When the cable insulation layer is axially cut, the cable insulation layer can be separated into two completely identical parts with the axis of the cable 100 as the center axis of symmetry, avoiding damage to the core of the cable 100 during cutting.

[0052] In one embodiment, the second drive assembly 14 includes a second drive motor 141, a second bidirectional screw 142, a first nut seat 143 and a second nut seat 144. The main shaft of the second drive motor 141 is connected to the second bidirectional screw 142, and the first nut seat 143 and the second nut seat 144 are respectively connected to the bidirectional threaded transmission of the second bidirectional screw 142. The second drive motor 141 drives the second bidirectional screw 142 to rotate, which can drive the first nut seat 143 and the second nut seat 144 to move towards or away from each other; the first ring cutter 111 is detachably connected to the first nut seat 143, and the second ring cutter 112 is detachably connected to the second nut seat 144. The second bidirectional screw 142 is driven to rotate by the second driving motor 141, and the first nut seat 143 and the second nut seat 144 can drive the first ring cutter 111 and the second ring cutter 112 to move in the direction of approaching or moving away from each other at the same time, so that the first ring cutter 111 and the second ring cutter 112 can always be symmetrical relative to the axis of the first moving component 21, so as to ensure that when the cable insulation layer is cut in the circumferential direction, the cutting depth and position of the first ring cutter 111 and the second ring cutter 112 are accurate, and the cutting depth on one side is avoided to damage the core of the cable 100. The cutting of the cable insulation layer can be achieved because the ring diameter of the first ring cutter 111 and the second ring cutter 112 needs to be compatible with the outer diameter of the cable 100. The first ring cutter 111 and the second ring cutter 112 are both set to be detachably connected, so that when cutting cables 100 of different specifications, the first ring cutter 111 and the second ring cutter 112 that are compatible with the outer diameter of the cable 100 of the specification can be replaced, so that the versatility of the stripping mechanism 1 is better.

[0053] The third driving assembly 15 includes a third driving motor 151, a lead screw 152 and a third nut seat 153. The main shaft of the third driving motor 151 is connected to the lead screw 152, the third nut seat 153 is connected to the lead screw 152, the first longitudinal cutter 121 is connected to the third nut seat 153, and the second longitudinal cutter 122 is connected to the second mounting seat 13. By setting the second longitudinal cutter 122 on the second mounting seat 13 and making it immovable and abutting against one side of the cable 100, when the third driving motor 151 is used to cut the cable insulation layer axially along the axial cutting of the cable 100, it is only necessary to drive the first longitudinal cutter 121 to move to abut against the other side of the cable 100, and the cable insulation layer can be cut axially without adjusting the positions of the first longitudinal cutter 121 and the second longitudinal cutter 122 in the direction perpendicular to the axis of the first moving assembly 21, so that accurate cutting can be achieved, and the core of the cable 100 is not damaged, while the stripping efficiency is improved.

[0054] Furthermore, the stripping mechanism 1 further includes a second guide assembly and a third guide assembly, the second guide assembly includes a second guide rod 16, the second guide rod 16 is arranged parallel to the second bidirectional screw 142, the first nut seat 143 and the second nut seat 144 both pass through the second guide rod 16, and the second guide rod 16 provides guidance for the movement of the first nut seat 143 and the second nut seat 144, so as to avoid the first ring cutter 111 and the second ring cutter 112 being deflected when the first nut seat 143 and the second nut seat 144 move, thereby damaging the core of the cable 100 during cutting. One or two second guide rods 16 can be provided, and if two second guide rods 16 are provided, one second guide rod 16 is provided on each side of the second bidirectional screw 142. The third guide assembly includes a third guide rod 17, which is arranged parallel to the screw 152. The third nut seat 153 passes through the third guide rod 17. The third guide rod 17 provides guidance for the movement of the third nut seat 153 to avoid the first ring cutter 111 being deflected relative to the second ring cutter 112 due to the deviation of the third nut seat 153 during movement, thereby damaging the core of the cable 100 during cutting.

The second moving component 22 drives the two clamping and centering mechanisms 3 to move synchronously through the first moving component 21 to clamp the two ends of the cable 100 respectively, ensuring that the axis of the cable 100 and the axis of the stripping mechanism 1 are located on the same straight line when the cable 100 is cut, thereby avoiding damage to the core of the cable 100 when cutting the cable insulation layer, and ensuring that the cable 100 is not damaged when the cable insulation layer is stripped.

The first mounting seat 31 is fixed to the end of the first movable component 21. The two clamping blocks 32 are relatively arranged on the first mounting seat 31, and the two clamping blocks 32 are symmetrically arranged on both sides of the axis of the first movable component 21. The two clamping blocks 32 can clamp the cable 100 by moving from a direction away from each other to a direction close to each other. The two clamping blocks 32 are symmetrically arranged on both sides of the axis of the first movable component 21. When clamping the cable 100, the two clamping blocks 32 move towards each other at the same time. After clamping the cable 100, it is ensured that the axis of the cable 100 and the axis of the first movable component 21 are located on the same straight line. Since the first circular cutter 111 and the second circular cutter 112 are symmetrically arranged on both sides of the axis of the first movable component 21, and the projections of the first longitudinal cutter 121 and the second longitudinal cutter 122 are both located on the axis of the first movable component 21, it is ensured that when cutting the cable insulation layer, the axis of the cable 100, the center lines of the first circular cutter 111 and the second circular cutter 112, and the center lines of the first longitudinal cutter 121 and the second longitudinal cutter 122 coincide, thereby ensuring the accuracy when cutting the cable insulation layer and not easily cutting the core of the cable 100.

[0059] Furthermore, the clamping and centering mechanism 3 also includes a first driving assembly 33, the first driving assembly 33 includes a first driving motor 331 and a first bidirectional screw 332, the main shaft of the first driving motor 331 is connected to the first bidirectional screw 332, the first bidirectional screw 332 is rotatably connected to the first mounting seat 31, the two clamping blocks 32 are respectively connected to the bidirectional thread transmission of the first bidirectional screw 332, the first driving motor 331 drives the first bidirectional screw 332 to rotate, and can drive the two clamping blocks 32 to move in a direction close to or away from each other. The first mounting seat 31 includes a mounting base plate 311 and mounting vertical plates 312 arranged on both sides of the mounting base plate 311, the first driving motor 331 is fixed on one of the mounting vertical plates 312, one end of the first bidirectional screw 332 is connected to the main shaft of the first driving motor 331 through a coupling, the main shaft of the first driving motor 331 is rotatably connected to the mounting vertical plate 312, and the other end of the first bidirectional screw 332 is rotatably connected to the other mounting vertical plate 312. The first driving motor 331 drives the first bidirectional screw 332 to rotate, and the two clamping blocks 32 move toward or away from each other.

[0060] Furthermore, the clamping and centering mechanism 3 further includes a first guide assembly, which includes two first guide rods 34, which are both arranged in parallel with the first bidirectional screw 332, and are respectively located on both sides of the first bidirectional screw 332; the two first guide rods 34 both pass through the two clamping blocks 32 and are connected to the first mounting seat 31. The two first guide rods 34 guide the translation of the clamping blocks 32, so as to avoid the two clamping blocks 32 from being deflected during the translation of the two clamping blocks 32 driven by the first bidirectional screw 332, thereby causing the axis of the clamped cable 100 to be deflected.

[0061] Furthermore, a clamping structure is provided on the side where the two clamping blocks 32 are close to each other, and the clamping structure is set as a V-shaped groove 321. When the two clamping blocks 32 are close to each other, the two side walls of the V-shaped groove 321 abut against the circumferential surface of the cable 100, and the cable 100 can be clamped between the two V-shaped grooves 321. When the two clamping blocks 32 move toward each other to clamp the cable 100, the circumference of the cable 100 gradually abuts against the two side walls of the V-shaped groove 321, and the axis of the cable 100 is adjusted during the movement of the two clamping blocks 32, so that when the two clamping blocks 32 clamp the cable 100, the projection of the axis of the cable 100 coincides with the axis of the first moving component 21.

[0062] Furthermore, the side walls of the V-shaped groove 321 are all configured as anti-slip friction surfaces. The anti-slip friction surfaces are in circumferential contact with the cable 100, increasing the friction between the side walls of the V-shaped groove 321 and the cable 100, and preventing the cable 100 from moving again after the two V-shaped grooves 321 clamp the cable 100. The friction surface can be configured as a concave-convex structure, such as convex patterns or convex dots.

[0063] The stripping device for the cable insulation layer provided in this embodiment comprises a stripping mechanism 1, a moving mechanism 2 and two clamping and centering mechanisms 3. The two clamping and centering mechanisms 3 are coaxially arranged at the two ends of the first moving component 21, and the axes of the two clamping and centering mechanisms 3 are parallel to the axis of the first moving component 21. The second moving component 22 drives the two clamping and centering mechanisms 3 to move synchronously through the first moving component 21 to clamp the two ends of the cable 100 respectively, so as to ensure that the axis of the cable 100 and the axis of the stripping mechanism 1 are located on the same straight line when the cable 100 is cut, thereby avoiding damage to the core of the cable 100 when cutting the cable insulation layer. The stripping mechanism 1 moves along the first moving component 21 to the first stripping position of the cable 100, and the first ring cutter 111 and the second ring cutter 112 move in a direction close to each other to clamp the circumference of the cable 100 and cut the cable insulation layer along the circumferential direction; then the stripping mechanism 1 moves along the first moving component 21 to the second stripping position of the cable 100, and cuts the cable insulation layer along the circumferential direction at the second stripping position. Then the first longitudinal cutter 121 and the second longitudinal cutter 122 move to the opposite sides of the cable 100 and abut against the cable 100, and the stripping mechanism 1 moves from the second stripping position to the first stripping position along the first moving component 21 to cut the cable insulation layer into the first part and the second part along the axial direction. Finally, the second moving component 22 drives the first longitudinal cutter 121 and the second longitudinal cutter 122 to move in turn along the extension direction of the second moving component 22 toward the direction close to the first part to strip the first part, and then moves toward the direction close to the second part to strip the second part, thereby realizing the rapid stripping of the cable insulation layer and improving the stripping efficiency. The stripping device for the cable insulation layer realizes the safe and efficient stripping of the cable insulation layer.
