Description

Technical Field

[0001] This utility model belongs to the technical field of cable processing equipment, and in particular relates to a high-speed cable aluminum foil stripping device. Background Technology

[0002] In the production and processing of high-speed cables, it is often necessary to remove the aluminum foil wrapping around the cable to facilitate subsequent welding and other processes.

[0003] Currently, the outer aluminum foil shielding layer of high-speed cables (such as coaxial high-speed cables and high-speed flexible flat cables) is mostly removed by manually cutting with a blade and then pulling it out. This method has the following drawbacks: 1. The cutting depth of the blade depends on manual experience, and it is difficult to precisely adjust the depth of the blade cutting into the aluminum foil. If the cutting depth is too shallow, the aluminum foil cannot be effectively cut, leading to difficulty in removal; if the cutting depth is too deep, it is easy to damage the core wire of the high-speed cable, which will also affect the performance and service life of the cable. 2. It is difficult to completely remove the aluminum foil when using a blade to pull it out, and aluminum foil residue is easily left on the high-speed cable. When the aluminum foil layer is tightly bonded to the core wire, the residue rate can be as high as 15%-30%. These residual aluminum foils may cause short circuits and other problems in subsequent welding processes, seriously affecting the performance and quality of the high-speed cable.

[0004] Therefore, there is an urgent need for an automatic stripping device that is adaptable, efficient, reliable, and clean in removing aluminum foil from high-speed cables, while avoiding cutting the core wires. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] The utility model embodiment provides a kind of high-speed cable aluminum foil stripping device, including rack and be installed on the clamping mechanism 200 of the rack, cutting mechanism, swing mechanism 400, specifically:

[0036] As Figure 1 And Figure 2As shown, the frame includes the installation base and support of other functional mechanisms, including the cabinet 100 for protecting the internal components from the external environment, the fixed platform for fixing the high-speed cable 700 and the clamping mechanism 200, and the lifting platform for installing the cutting mechanism and the swing mechanism 400.

[0037] The cabinet 100 is made of metal plates and has a vertical back plate 101 with a certain thickness. The fixed platform includes a first fixed plate 102 and a second fixed plate 103 arranged face to face. The first fixed plate 102 is vertically fixed on the back plate 101 of the cabinet 100 by a fixed block 104. The second fixed plate 103 is fixed on the back plate 101 by two symmetrically arranged fixed rods 105. The second fixed plate 103 is parallel to the first fixed plate 102 and maintains a certain distance. The lifting platform is located below the fixed platform and can be lifted up and down relative to the fixed platform. The lifting platform includes a first linear motion mechanism and a lifting plate 111. The first linear motion mechanism includes a first mounting bracket 106 fixed on the back plate 101 by bolts, a first linear slide rail 107 vertically fixed on the first mounting bracket 106, a first linear slide table 108 in sliding cooperation with the first linear slide rail 107, a second mounting bracket 109 fixedly connected with the first linear slide table 108, and a first driving mechanism 110 for driving the first linear slide table 108 to slide up and down along the first linear slide rail 107. The first driving mechanism 110 is a telescopic air cylinder or an electric push rod. The main body of the first driving mechanism 110 is fixed on the lower part of the back plate 101. The execution part of the first driving mechanism 110 is connected with the first linear slide table 108 through a transmission rod. The lifting plate 111 is horizontally fixed on the second mounting bracket 109 and can be lifted up and down with the sliding of the first linear slide table 108. In this embodiment, the first mounting bracket 106 and the second mounting bracket 109 are made of aluminum profiles, which are easy to assemble and maintain, can ensure good installation precision and straightness, and provide accurate installation reference for functional components in the equipment.

[0038] As Figures 2 to 4As shown, in the embodiment, the clamping mechanism 200 is used to clamp and fix the high-speed cable 700 to be cut, which comprises a cable clamp 201 and a pressing member 204. Wherein, the cable clamp 201 is detachably fixedly installed on the first fixed plate 102, which comprises a clamping plate 202 and a pressing handle 203 linked with the clamping plate 202, and the correct position of the cable can be clamped by pressing the pressing handle 203, so as to expose the part to be cut. Through this pre-clamping operation, the cable can be quickly installed on the cutting device, saving installation time and improving work efficiency. At the same time, it can also ensure the accuracy of the cutting position, avoid deviation during installation and cutting, and improve the cutting quality.

[0039] The pressing member 204 is horizontally installed on the second fixed plate 103, and the pressing member 204 comprises a second driving mechanism 205, a second linear slide rail 206, a second linear slide table 207 and a pressing plate 208. The second linear slide rail 206 is fixedly installed on the second fixed plate 103, the second linear slide table 207 is in sliding fit with the second linear slide rail 206 and can slide along the second linear slide rail 206 horizontally towards the first fixed plate 102, and the pressing plate 208 is fixed on the end face of the second linear slide table 207, and a buffer pad is further arranged on the pressing surface of the pressing plate 208 to avoid crushing the high-speed cable 700 and the cable clamp 201. The second driving mechanism 205 is also a telescopic cylinder, and the cylinder body of the telescopic cylinder is fixed on the second fixed plate 103, and the telescopic rod of the telescopic cylinder is parallel to the second linear slide rail 206 and movably connected with the second linear slide table 207. By driving the second driving mechanism 205, the pressing plate 208 can be driven to move towards the cable clamp 201 to press the pressing handle 203, and the cable clamp 201 can further press the high-speed cable 700 by the stable pressure of the telescopic cylinder, so as to ensure that the cable does not loosen or shift during cutting and ensure the smooth cutting.

[0040] As Figures 4 to 6As shown, as a preferred embodiment, the cutting mechanism is installed below the clamping mechanism 200 for cutting the clamped and fixed high-speed cable 700. Specifically, the cutting mechanism includes a third driving mechanism 301, a third linear slide rail 302, a third linear slide table 303, and a cutting knife 304. The third linear slide rail 302 is horizontally fixed on the upper surface of the lifting plate 111. The third linear slide table 303 has two parts, one of which is fixed at the end of the stroke of the third linear slide rail 302, and the other of which is in sliding cooperation with the third linear slide rail 302. The cutting knife 304 includes two knife seats 305 and two knife blades 306. The two knife seats 305 are mirror installed on the two second linear slide tables 207. A fixing groove for horizontally fixing the knife blade 306 is formed in the middle of the knife seat 305. A clamping surface protruding outward for clamping the outer skin of the high-speed cable 700 is arranged below the fixing groove. The clamping surface is provided with anti-slip micro serration structure to facilitate the downward peeling of the aluminum foil after cutting. The two knife blades 306 of the cutting knife 304 are respectively detachably fixed in the two knife seats 305 by bolts. The cutting edge of the knife blade 306 protrudes from the knife seat 305 by a certain width. By controlling the width of the knife blade 306 exposed to the knife seat 305, the cutting depth of the knife blade 306 can be controlled to a certain extent. The main body of the third driving mechanism 301 is fixed on the upper surface of the lifting plate 111. The execution part of the third driving mechanism 301 is connected with the third linear slide table 303. The third driving mechanism 301 can drive the cutting knife 304 to move close to each other, thereby realizing the cutting of the high-speed cable 700.

[0041] As shown in Figure 7 and Figure 8 In this embodiment, the swinging mechanism 400 is arranged below the cutting mechanism for swinging the high-speed cable 700. Specifically, the swinging mechanism 400 includes a fourth driving mechanism 401, a fourth linear slide rail 402, a fourth linear slide table 403, and a swing arm 404. The fourth linear slide rail 402 is horizontally fixed and installed on the lower surface of the lifting plate 111 parallel to the cutting direction of the cutting mechanism. The fourth linear slide table 403 is slidingly installed on the fourth linear slide rail 402. The swing arm 404 includes a vertical rod 405 fixed on the fourth linear slide table 403 and two horizontal rods 406 horizontally arranged at the top end of the vertical rod 405. The two horizontal rods 406 are parallel to each other and spaced apart by a certain gap, so that high-speed cables 700 of various specifications (such as coaxial high-speed cables 700 and high-speed flexible flat cables) can all pass through the gap between the two horizontal rods 406. The fourth driving mechanism 401 also adopts a telescopic cylinder. Through the fourth driving mechanism 401, the swing arm 404 can swing the end of the cut high-speed cable 700 back and forth along the cutting direction, thereby ensuring that the aluminum foil of the high-speed cable 700 is cut more cleanly.

[0042] To further ensure the motion accuracy of each linear motion mechanism, as a preferred embodiment, a displacement sensor is further arranged on the linear slide rail of the lifting platform, the cutting mechanism and the swing mechanism 400, and the displacement sensor is a slot photoelectric switch 500, and correspondingly, a light barrier 600 is arranged on each linear slide table to cooperate with the slot photoelectric switch 500, so as to accurately limit the maximum motion stroke of each linear motion mechanism.

[0043] The specific working process of the high-speed cable 700 aluminum foil stripping device is as follows: when it is necessary to strip the aluminum foil of the high-speed cable 700, first, the high-speed cable 700 is pre-clamped by the cable clamp 201, and then is installed on the first fixed plate 102, and the high-speed cable 700 is further clamped by the pressing part 204 of the clamping mechanism 200. Then the third driving mechanism 301 of the cutting mechanism is controlled to drive the cutting knife 304 to slide on the third linear slide table 303, and the aluminum foil is cut. During the cutting process, the cutting depth of the cutting knife 304 is accurately controlled by the width of the blade 306 exposed relative to the cutter seat 305 and the cooperation of the displacement sensor, so as to avoid cutting the core wire. After cutting, the swing mechanism 400 is started to drive the swing arm 404 to swing on the fourth linear slide table 403, and the cut aluminum foil is swung to cut the aluminum foil completely and avoid residue. Finally, the lifting platform is driven to descend, and the cut aluminum foil is stripped from the high-speed cable 700 body, and after stripping, the telescopic cylinder of the clamping mechanism 200 is controlled to release the pressing plate 208, and the high-speed cable 700 after stripping the aluminum foil is taken out.

[0044] The above-described embodiments only express the implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
