Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6The utility model provides a technical solution: a peeling mechanism, including a first driving device 1, the first driving device 1 is provided with a peeling module 2 connected thereto, wherein the peeling module 2 includes a peeling head 3 and a brushless DC motor 4 matched with the peeling head 3, and also includes a mounting base 6, wherein the first driving device 1 includes a first servo motor 10 connected to the mounting base 6 and a first screw rod 11 matched with the first servo motor 10, wherein the first driving device 1 also includes a slide 12 matched with the first screw rod 11, wherein the peeling module 2 includes a bottom plate 20 fixedly connected to the slide 12, so that the first servo motor 10 drives the first screw rod 11 to rotate, thereby driving the slide 12 to slide on the mounting base 6, thereby driving the bottom plate 20 to slide synchronously, and then driving the entire peeling module 2 to move, and because the peeling module 2 is provided with a peeling head 3, by driving the peeling module 2 to slide, it is equivalent to moving the peeling head 3 so that one end of the cable is inserted into the peeling head 3 for peeling the cable skin.

[0024] The peeling head 3 includes a peeling cylinder 38, one end of which is provided with a limit plate 31 that cooperates with the peeling cylinder 38 to limit the position. The peeling cylinder 38 is also provided with an end plate 32 at the end provided with the limit plate 31, wherein the end plate 32 is fixedly connected to the peeling cylinder 38, which is equivalent to the limit plate 31 being located between the end plate 32 and the peeling cylinder 38. The peeling cylinder 38 is provided with a groove at this end that can just accommodate the limit plate 31, so the limit plate 31 can be placed in the groove and then connected between the end plate 32 and the peeling cylinder 38 so that the limit plate 31 is located between the end plate 32 and the peeling cylinder 38.

[0025] The rotary cutting head 3 also includes a rotating head 33 located inside the rotary cutting cylinder 38, wherein the rotating head 33 and the rotary cutting cylinder 38 are limited and slidably matched. When the rotating head 33 rotates, it can drive the rotary cutting cylinder 38 to rotate synchronously. One end of the rotating head 33 is provided with four connecting strips 34, wherein the connecting strips 34 respectively penetrate one end of the rotary cutting cylinder 38 and also penetrate the limiting plate 31. A cutter 30 is also provided inside the rotary cutting head 3, wherein the cutter 30 and the connecting strips 34 are limited and matched, and the cutter 30 is clamped between the limiting plate 31 and the rotary cutting cylinder 38, wherein the connecting strips 34 are inclined relative to the rotating head 33, and several connecting strips 34 are arranged inwardly relative to one end of the rotating head 33. A through hole 35 for the cable to pass through for rotary cutting is provided in the middle of the limiting plate 31 and the end plate 32. When the cable is to be cut and stripped, it is necessary to drive the rotary cutting module 2 to move so that the cable can pass through the through hole 35, thereby facilitating the cutter 30 in the rotary cutting head 3 to cut and strip the cable.

[0026] A transmission shaft 36 is provided at one end of the rotating head 33 and is connected thereto. A transmission gear 37 is slidably connected to the transmission shaft 36. A transmission belt is used to connect the brushless DC motor 4 and the transmission gear 37 in a transmission manner. When cutting and stripping the cable, the brushless DC motor 4 can drive the transmission gear 37 to rotate through the transmission belt, thereby driving the transmission shaft 36 to rotate, and further driving the cutter 30 located on the rotating head 33 and in limit fit with the connecting strip 34 to rotate, so as to cut and strip the cable. A sliding seat 21 is rotatably connected to the other end of the transmission shaft 36. A limit bearing is provided inside the sliding seat 21, and the transmission shaft 36 is in limit fit with the limit bearing. In this way, when the transmission shaft 36 rotates, it is rotatably connected to the limit bearing. A guide rail 22 is also provided on the bottom plate 20, and the sliding seat 21 is slidably engaged with the guide rail 22. The rotary cutting module 2 further includes a second driving device 5 for controlling the feed amount of the cutter 30 when cutting and stripping the cable. The second driving device 5 includes a second servo motor 50 installed on the bottom plate 20. The second servo motor 50 is drivingly connected to a second lead screw 51. The second lead screw 51 is in driving cooperation with the sliding seat 21. Therefore, by driving the second lead screw 51 to rotate by using the second servo motor 50, while the second lead screw 51 rotates, it drives the sliding seat 21 to slide. Since the sliding seat 21 is in limit rotational fit with the transmission shaft 36, when the sliding seat 21 moves, it drives the transmission shaft 36 to slide synchronously, thereby driving the rotating head 33 located at one end of the transmission shaft 36 to move horizontally. Since the connecting strip 34 on the rotating head 33 is inclined, and the cutter 30 in limit fit with the connecting strip 34 is clamped between the limit plate 31 and the rotary cutting cylinder 38, when the rotating head 33 moves horizontally, it drives the connecting strip 34 to slide horizontally, thereby changing the limit position between the cutter 30 and the connecting strip 34. Since the connecting strip 34 on the rotating head 33 is inclined relative to the horizontal plane in the transverse direction of the rotating head 33, when changing the limit position between the cutter 30 and the connecting strip 34, the longitudinal position of the cutter 30 is also changed, thereby changing the feed amount of the cutter 30 for the cable, and further controlling the cutting depth of the cutter 30 for the cable, so as to adapt to the cutting and stripping of multi-layer cables.

[0027] A support plate 23 connected thereto is also provided on the base plate 20, and a brushless DC motor 4 is fixedly connected to the support plate 23, wherein a transmission shaft 36 passes through the support plate 23, so that the rotary cutting head 3 is located on one side of the support plate 23, and a wire pressing device 7 for positioning the cable is provided on the support plate 23, and the wire pressing device 7 is located above the rotary cutting head 3, and the wire pressing device 7 comprises a driving cylinder 71 fixedly mounted on the support plate 23, wherein the driving cylinder 71 is provided with a wire pressing seat 70 connected thereto by transmission, and when the cable is ready to be cut and stripped, the driving cylinder 71 drives the wire pressing seat 70 to descend to press and position the cable, thereby preventing the cable from moving during cutting and stripping and affecting the cutting and stripping quality, and a collecting bucket 8 for collecting cutting and stripping waste is also provided below the rotary cutting head 3, and the collection bucket 8 can collect the cut and stripped wire skin in time, thereby ensuring the cleanliness of the equipment, and an air blowing pipe is also provided on the support plate 23, and the wire skin waste falling on the base plate 20 can be blown away and cleaned by the air blowing pipe.

[0028] The working principle of the utility model is as follows: when it is necessary to cut and strip the cable, the first servo motor 10 is first used to drive the first screw rod 11 to rotate, thereby driving the slide 12 to slide the first screw rod 11 in the horizontal direction. Since the bottom plate 20 of the peeling module 2 is fixedly connected to the slide 12, the peeling module 2 will be driven to slide synchronously when the slide 12 slides, so that the cable passes through the through hole 35 and extends into the peeling head 3. Four cutters 30 are provided in the peeling head 3, and the cutters 30 are limitedly matched with the inwardly inclined connecting strips 34. Then, the second servo motor 50 is used to drive the second screw rod 51 to rotate, thereby driving the slide 21 to slide in the horizontal direction of the second screw rod 51. Since the slide 21 is connected to the transmission shaft 36 for limited rotation, the transmission shaft 36 will also be driven when the slide 21 moves. The horizontal movement drives the connecting strip 34 on the rotating head 33 to move, so that the limit position between the cutter 30 and the connecting strip 34 can be changed, thereby changing the contact feed amount of the cutter 30 for the cable, which is equivalent to changing the cutting depth of the cutter 30 for the cable, so that it can adapt to the cutting and stripping of multiple layers of cables. After controlling the contact feed amount of the cutter 30 for the cable, the brushless DC motor 4 drives the transmission belt to rotate, thereby driving the transmission gear 37 to rotate, and then driving the transmission shaft 36 to rotate, and driving the cutter 30 to rotate to cut the cable cortex. After cutting, the first servo motor 10 is used to drive the entire rotary cutting module 2 to move, thereby driving the cutter 30 to move in the horizontal direction, and then using the side of the cutter 30 to peel off the cut wire skin, thereby completing the cable cortex cutting and stripping.

[0029] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model.
