Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, specifically a cable sheathing device based on vision grasping control servo adaptive. Background Technology

[0002] During the production, repair, and subsequent processing of cables, it is often necessary to peel off (i.e., break) the outer sheath of the cable in order to perform operations such as conductor connection and insulation testing.

[0003] Currently, the cable sheathing equipment commonly available on the market is mainly divided into two categories: manual sheathing tools and semi-automatic sheathing equipment. Manual sheathing tools rely on operators to manually position and exert force, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the sheathing accuracy. It is easy to cause problems such as cutting the outer sheath too deeply and damaging the internal conductor, or cutting too shallowly and causing the outer sheath to not be able to be peeled off smoothly. Especially for cables with different diameters and different sheathing materials, manual operation is extremely unsuitable. While semi-automatic cable sheathing equipment reduces labor intensity to some extent, it still has significant drawbacks. These devices typically require manual clamping of the cable onto specific fixtures before cutting through the sheath using a pre-set mechanical structure, failing to achieve automatic cable gripping and positioning. Furthermore, the motion parameters of their cutting mechanisms are often fixed, requiring manual adjustment of parameters when dealing with cables of different specifications (diameter, sheath thickness). This cumbersome operation and low adjustment precision fail to meet the demands of modern production for automation, precision, and efficiency in cable sheathing. In addition, some semi-automatic equipment lacks real-time monitoring and feedback mechanisms, making it impossible to adjust cutting force and speed promptly, which can easily lead to unstable sheathing quality due to cable misalignment or uneven material composition.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1 to 7 According to an embodiment of this utility model, a technical solution is provided: a cable stripping device based on vision grasping control servo adaptive, comprising: a base box 1, on the surface of the base box 1, a guide sleeve 2, a straightening component 4, a conveying component 3 and a stripping component 5 are connected sequentially from left to right; the straightening component 4 is provided in two sets, located on the left and right sides of the conveying component 3 respectively; the stripping component 5 includes a second bracket 54 connected to the base box 1, and cutting wheels 56 are connected to both the upper and lower ends of the second bracket 54. The cutting wheels 56 are connected to the second bracket 54 through a connecting shaft 55 and a third connecting plate 53. The third connecting plate 53 is concave in shape, and the left and right ends of the connecting shaft 55 are connected to the left and right ends of the third connecting plate 53. The connecting shaft 55 passes through the cutting wheels 56 and is fixedly connected to the cutting wheels 56, and one end is connected to a third motor 52.

[0017] The guide sleeve 2 device with the above-mentioned structure can play a preliminary guiding role for the cable, so that the cable can enter the subsequent components more accurately. The straightening component 4 can straighten the bent cable and ensure the stability of the cable during the conveying and sheathing process. The two sets of straightening components 4 straighten the cable from different directions to further improve the straightening effect. The conveying component 3 is responsible for smoothly conveying the cable to the sheathing component 5, ensuring the orderly movement of the cable in the entire sheathing process. When the third motor 52 is started, it can drive the connecting shaft 55 to rotate, thereby causing the cutting wheel 56 to rotate at high speed. The cutting wheels 56 at the upper and lower ends can cut the cable sheath from different angles. During the cutting process, the speed, torque and other parameters of the third motor 52 can be precisely controlled by the servo system to adapt to cables with different diameters and sheath thicknesses, so as to achieve precise sheathing.

[0018] In this embodiment, the left and right ends of the third connecting plate 53 are slidably connected to the second bracket 54. The top of the second bracket 54 is connected to the second telescopic cylinder 51. The output end of the second telescopic cylinder 51 is connected to the third connecting plate 53 connected to the upper end of the second bracket 54. The bottom end of the second bracket 54 is also connected to the baffle 57. The cutting wheel 56 at the bottom end of the second bracket 54 passes through the baffle 57, and the baffle 57 is inclined. The bottom end of the baffle 57 is also provided with a collection groove 58.

[0019] When the servo system issues an adjustment command based on the cable specifications (such as diameter and sheath thickness) recognized by vision, the second telescopic cylinder 51 can push or pull the upper third connecting plate 53 to slide along the second bracket 54, thereby driving the upper cutting wheel 56 to move up and down, and precisely adjusting the distance between the upper and lower cutting wheels 56. For example, when facing a cable with a larger diameter, the cylinder drives the upper cutting wheel 56 to move up, expanding the cutting channel; for cables with thicker sheaths, the cylinder fine-tunes the distance between the cutting wheels 56 to ensure that the cutting depth just penetrates the sheath without damaging the internal conductor. The inclined baffle 57 connected to the bottom of the second bracket 54 not only protects the bottom cutting wheel 56 and prevents external impurities from interfering with the cutting process, but its inclination angle (usually designed to be 30°-45°) can also guide the outer sheath waste generated during cutting to slide down the plate surface. The collection groove 58 at the bottom of the baffle 57 can directly receive the sliding waste, realizing the centralized collection of waste.

[0020] The straightening assembly 4 includes a base 42 connected to the top of the base box 1. The front and rear ends of the base 42 are connected to second connecting plates 43. Multiple straightening rollers 46 are connected to the opposite surfaces of the two second connecting plates 43. An extension block 44 is also provided at the bottom of the second connecting plate 43. A double-ended lead screw 45 is connected below the base 42. The double-ended lead screw 45 passes through the extension blocks 44 at the bottom of the two second connecting plates 43 and is threaded to them. The double-ended lead screw 45 is connected to the second motor 41.

[0021] Multiple straightening rollers 46 are connected to the opposing surfaces of the second connecting plates 43 at both ends of the base 42, forming a wrap-around straightening channel for the cable. The extension block 44 at the bottom of the second connecting plate 43 is threadedly connected to the double-ended lead screw 45 below the base 42, and the double-ended lead screw 45 is driven by the second motor 41. When facing cables of different diameters, the second motor 41 drives the double-ended lead screw 45 to rotate. Since the threads at both ends of the double-ended lead screw 45 are opposite, it will drive the two second connecting plates 43 to move closer or further away synchronously, thereby adjusting the distance between the front and rear straightening rollers 46. For thin-diameter cables, the connecting plates move closer to reduce the distance to ensure moderate straightening force. For thick-diameter cables, the connecting plates move further away to increase the distance to avoid excessive compression and damage to the cable. The design of multiple straightening rollers 46 can roll and straighten the cable from multiple angles, forming a continuous straightening action in conjunction with the conveying direction. This completely solves the problems of incomplete straightening by a single roller and easy cable deviation, providing a stable "straight input" for the subsequent exfoliation process.

[0022] The conveying assembly 3 includes a first bracket 33 connected to the surface of the base box 1. A lower conveying roller 36 is connected to the lower end of the first bracket 33. One end of the lower conveying roller 36 is connected to the first motor 32 through a gear and rack. A first connecting plate 34 is slidably connected to the upper end of the first bracket 33. The first connecting plate 34 is concave in shape and an upper conveying roller 35 is connected between its left and right sides. A first telescopic cylinder 31 is connected to the top of the first bracket 33. The output end of the first telescopic cylinder 31 is connected to the top of the first connecting plate 34.

[0023] The lower conveying roller 36 at the lower end of the first bracket 33 is connected to the first motor 32 via a gear and rack. The motor drives the lower conveying roller 36 to rotate at a constant speed, providing power for cable conveying. The first connecting plate 34 ("concave" shaped structure) at the upper end of the first bracket 33 is slidably connected to the upper end. The upper conveying roller 35 between the left and right sides of the connecting plate corresponds to the lower conveying roller 36. The output end of the first telescopic cylinder 31 at the top of the first bracket 33 is connected to the top of the first connecting plate 34. When the cable enters the conveying assembly 3, the first telescopic cylinder 31 pushes the first connecting plate 34 down along the bracket according to the cable diameter fed back by the vision system, driving the upper conveying roller 35 to press down until the upper and lower conveying rollers 36 stably clamp the cable (the clamping force is precisely controlled by the cylinder pressure to avoid damage to the cable due to excessive tightness or slippage due to excessive looseness).

[0024] Working principle: This equipment, centered on visual recognition and a central control system, operates collaboratively according to the process of "preparation – guidance – straightening – conveying – sheathing – waste disposal." First, the vision system scans the cable specifications and transmits the data to the central control system, calculating the appropriate parameters for straightening, conveying, and sheathing. Then, the cable is precisely fed into the guide sleeve 2 and passes through two sets of straightening components 4 (motor-driven double-headed lead screw 45 adjusts the spacing of straightening rollers 46, multi-roller rolling straightening) to ensure straightness. Subsequently, the conveying component 3 (motor-driven lower roller rotation, cylinder-adjusted upper roller for adaptive clamping) smoothly delivers the cable to the sheathing component 5. During sheathing, the cylinder adjusts the spacing of the cutting wheels 56, and the motor drives the cutting wheels 56 to cut the outer sheath at high speed. The cutting waste slides along the inclined baffle 57 into the collection tank 58 for centralized processing. Throughout the process, sensors provide real-time feedback, and the central control system dynamically adjusts parameters to ensure accurate and stable sheathing.
