Description

Technical Field

[0001] This utility model relates to the field of wire stripping equipment technology, specifically a fully automatic wire stripping and separating device. Background Technology

[0002] In the traditional wire processing industry, manual operation or semi-automated equipment still dominates the stripping and sorting process for wires wrapped with multiple strands. In manual operation, workers must use utility knives to slice open the wire sheath section by section, then rely on visual inspection and finger dexterity to sort the strands. This is not only inefficient but also prone to occupational health problems such as finger strain due to repetitive labor. While semi-automated equipment introduces simple mechanical transmission devices to assist in wire feeding and cutting, it still requires full-process human monitoring and intervention, failing to meet the demands for efficient and high-precision processing of multi-specification wires. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a fully automatic wire stripping and splitting device that automatically strips, splits, and rewinds the outer sheath of multiple wire bundles, solving the problems of low efficiency, insufficient precision, and poor adaptability in traditional manual or semi-automatic processing.

[0004] The technical solution adopted by this utility model is as follows: a fully automatic wire stripping and separating device, including a workbench, on which a wire feeding mechanism, a sheathing mechanism, a wire pressing and separating mechanism, and a winding mechanism are arranged in sequence along the processing direction, and a movable wire clamping mechanism is arranged on the side of the workbench.

[0005] The wire feeding mechanism includes an upper wire feeding drum and a lower wire feeding drum that are positioned opposite each other. The surfaces of the upper wire feeding drum and the lower wire feeding drum are provided with friction stripes to enhance friction. The wire is fed to the opening mechanism through the clamping area between the two drums.

[0006] The opening mechanism is arranged adjacent to the wire feeding mechanism, including an upper opening drum and a lower opening drum that are positioned opposite each other. A ring of blades is respectively arranged in the middle of the upper opening drum and the lower opening drum. A cutting area is formed between the ring blades, and the cutting area coincides with the central axis of the clamping area.

[0007] The wire pressing and separating mechanism is connected to the sheath opening mechanism, including a first conveyor belt group and a second conveyor belt group arranged in parallel. A compression gap adapted to the diameter of the wire is formed between the first conveyor belt group and the second conveyor belt group. After the wire with its sheath cut open by the sheath opening mechanism enters the gap, the first conveyor belt group and the second conveyor belt group drive the wire forward. At the same time, the compression action between the conveyor belts separates the wire bundle inside the wire from the cut sheath.

[0008] The winding mechanism includes multiple winding shafts and a servo motor that drives them to rotate;

[0009] The wire clamping mechanism includes a multi-axis robotic arm, a gripper fixedly installed at the front end of the multi-axis robotic arm, and a vision recognition module linked to the gripper. The vision recognition module is used to identify a single wire harness, and the gripper is used to clamp the single wire harness and send it to the winding spool.

[0010] It also includes drive components that provide power to the wire feeding mechanism, the wire opening mechanism, and the wire pressing and separating mechanism.

[0011] Furthermore, the lower feed drum and the lower open-skin drum are waist-shaped with a small diameter in the middle and a large diameter at both ends, while the upper feed drum and the upper open-skin drum are spindle-shaped with a large diameter in the middle and a small diameter at both ends.

[0012] Furthermore, the visual recognition module includes an industrial camera and an image processing unit. The industrial camera acquires image information, and the image processing unit processes the image information to identify the position of a single wire harness.

[0013] Furthermore, the wire feeding mechanism also includes a wire feeding stand fixed on the workbench, with both ends of the lower wire feeding drum rotatably engaged with the wire feeding stand, the upper wire feeding drum rotatably mounted on the wire feeding movable seat, the wire feeding movable seat slidably engaged with the wire feeding stand, and the wire feeding movable seat connected to a lifting mechanism, the lifting mechanism driving the wire feeding movable seat to move vertically, adjusting the axial distance between the upper and lower wire feeding drums to accommodate wires of different diameters.

[0014] Furthermore, the opening mechanism also includes an opening support frame fixed on the workbench, with both ends of the lower opening drum rotatably engaged with the opening support frame, and the upper opening drum rotatably mounted on the opening movable seat. The opening movable seat is slidably engaged with the opening support frame, and the opening movable seat is connected to a lifting mechanism. The lifting mechanism drives the opening movable seat to move vertically, and the axial distance between the upper and lower opening drums is adjusted to accommodate wires of different diameters.

[0015] Furthermore, a visual diameter sensor for detecting the outer diameter of the wire entering the clamping area is installed on the wire feeding stand. The visual diameter sensor is signal-connected to the control unit of the lifting mechanism. The control unit drives the lifting mechanism to operate according to the detected outer diameter data of the wire, so as to automatically adjust the clamping area distance between the upper and lower wire feeding drums, as well as the cutting area distance between the annular blades on the upper and lower open drums.

[0016] Furthermore, the length of the first conveyor belt group is less than the length of the second conveyor belt group, and the side of the second conveyor belt group near the winding mechanism extends beyond the first conveyor belt group, forming a space that facilitates the grippers of the clamping mechanism to grasp the single wire bundle after it has been separated by the wire pressing and separating mechanism.

[0017] Furthermore, the workbench surface is provided with a hollow guide groove in the section between the wire pressing and separating mechanism and the winding mechanism. The hollow guide groove is used to guide the outer sheath of the wire stripped by the wire pressing and separating mechanism from the outside of the workbench.

[0018] Furthermore, the edge of the workbench is provided with a ring-shaped guide rail. The multi-axis robotic arm moves and engages with the ring-shaped guide rail via a movable base. The movable base is provided with a motion drive component that forms a motion coupling with the ring-shaped guide rail, which is used to drive the movable base to move circumferentially along the ring-shaped guide rail, so that the working range of the multi-axis robotic arm covers the entire circumferential operating area of ​​the workbench.

[0019] Furthermore, the winding mechanism includes two rows of winding shafts, which are arranged in a staggered manner.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) This utility model realizes automatic wire feeding and precise wire cutting through the linkage control of the wire feeding mechanism and the sheathing mechanism. The sheathing mechanism cuts the upper and lower surfaces of the wire synchronously through the symmetrically arranged ring blades, which provides conditions for the subsequent separation of the sheath and the wire bundle.

[0022] (2) The wire separation mechanism continuously applies linear extrusion force during the wire conveying process, so that the cut outer skin and the inner wire bundle gradually separate in motion. Combined with the staggered design of the first conveyor belt group and the second conveyor belt group, an exposed wire bundle area is formed to avoid the interference of the conveyor belt on the clamping action and ensure that the wire clamping mechanism accurately grasps the wire.

[0023] (3) The wire clamping mechanism is based on the vision recognition module to position a single wire harness. It works with the multi-axis robotic arm to move along the ring guide rail for the whole circumference, so as to realize the multi-angle adaptive clamping of the wire harness from the separation station to the winding shaft. Combined with the staggered winding shaft group, it avoids spatial conflicts when the wire harness is wrapped, and improves the winding density and neatness.

[0024] (4) By synchronously adjusting the spacing of the wire feeding drum, the cutting depth of the annular blade and the extrusion gap of the conveyor belt group, the processing needs of wires of different specifications can be met;

[0025] (5) The wire feeding, cutting, separating and winding processes are integrated into a continuous workflow to achieve efficient and high-precision closed-loop control of the entire wire stripping and splitting process. Attached Figure Description

[0030] To facilitate understanding of this utility model, the following description will be more comprehensive and detailed in conjunction with the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0031] like Figures 1-4 As shown, this embodiment provides a fully automatic wire stripping and separating device, including a workbench 100 and a drive assembly. The workbench 100 is provided with a wire feeding mechanism 200, a sheathing mechanism 300, a wire pressing and separating mechanism 400, and a winding mechanism 500 arranged sequentially along the processing direction. A movable wire clamping mechanism 600 is provided on the side of the workbench 100.

[0032] The wire feeding mechanism 200 includes an upper wire feeding drum 203 and a lower wire feeding drum 202 that are positioned opposite each other. The surfaces of the upper wire feeding drum 203 and the lower wire feeding drum 202 are provided with friction stripes to enhance friction. The upper wire feeding drum 203 and the lower wire feeding drum 202 are driven to rotate synchronously in opposite directions by a drive assembly, or one of the wire feeding drums rotates while the other wire feeding drum moves accordingly, so as to convey the wire through the clamping area between the two to the opening mechanism 300.

[0033] The wire cutting mechanism 300 is arranged adjacent to the wire feeding mechanism 200 and includes an upper cutting drum 303 and a lower cutting drum 302 that are positioned opposite each other. A ring blade 304 is respectively arranged in the middle of the upper cutting drum 303 and the lower cutting drum 302. A cutting area is formed between the ring blades 304, and the cutting area coincides with the central axis of the clamping area. The upper cutting drum 303 and the lower cutting drum 302 are driven to rotate synchronously in opposite directions by a driving component, or one of the cutting drums rotates and the other cutting drum moves accordingly, so as to complete the simultaneous cutting of the upper and lower surfaces of the wire.

[0034] The wire separation mechanism 400 is connected to the sheathing mechanism 300 and includes a first conveyor belt group 401 and a second conveyor belt group 402 arranged in parallel. A compression gap adapted to the diameter of the wire is formed between the first conveyor belt group 401 and the second conveyor belt group 402. After the wire with its sheath cut open by the sheathing mechanism 300 enters the gap, the first conveyor belt group 401 and the second conveyor belt group 402 are driven by a drive component to achieve reverse differential speed operation. While driving the wire forward, the compression action between the conveyor belts separates the wire bundle inside the wire from the cut sheath.

[0035] The winding mechanism 500 includes multiple winding shafts 501 and servo motors that drive them to rotate, for winding up separate single wire bundles.

[0036] The wire clamping mechanism 600 includes a multi-axis robotic arm 603, a gripper 601 fixedly installed at the front end of the multi-axis robotic arm 603, and a vision recognition module 602 linked with the gripper 601. The vision recognition module 602 is used to identify a single wire harness and includes an industrial camera and an image processing unit. The industrial camera acquires image information, and the image processing unit processes the image information to identify the position of the single wire harness. The gripper 601 is used to clamp the single wire harness and send it to the winding spool 501.

[0037] The drive assembly provides power to the wire feeding mechanism 200, the wire opening mechanism 300, and the wire pressing and separating mechanism 400.

[0038] In another embodiment, the lower feed drum 202 and the lower open-end drum 302 are waist-shaped with a small diameter in the middle and a large diameter at both ends, while the upper feed drum 203 and the upper open-end drum 303 are shuttle-shaped with a large diameter in the middle and a small diameter at both ends. The combination of the waist-shaped and shuttle-shaped drums allows the wire to be automatically centered and positioned in the clamping and cutting areas, avoiding radial offset during conveying or cutting.

[0039] In another embodiment, the wire feeding mechanism 200 further includes a wire feeding stand 201 fixed on the workbench 100. The two ends of the lower wire feeding drum 202 are rotatably engaged with the wire feeding stand 201. The upper wire feeding drum 203 is rotatably mounted on the wire feeding moving seat. The wire feeding moving seat is slidably engaged with the wire feeding stand 201. The wire feeding moving seat is connected to a lifting mechanism. The lifting mechanism drives the wire feeding moving seat to move vertically and adjusts the axial distance between the upper wire feeding drum 203 and the lower wire feeding drum 202 to accommodate wires of different diameters.

[0040] The opening mechanism 300 also includes an opening support frame 301 fixed on the workbench 100. The two ends of the lower opening drum 302 are rotatably engaged with the opening support frame 301. The upper opening drum 303 is rotatably mounted on the opening movable seat. The opening movable seat is slidably engaged with the opening support frame 301. The opening movable seat is connected to a lifting mechanism. The lifting mechanism drives the opening movable seat to move vertically. The axial distance between the upper opening drum 303 and the lower opening drum 302 is adjusted to accommodate wires of different diameters.

[0041] The wire feeding stand 201 is equipped with a visual diameter sensor 205 for detecting the outer diameter of the wire entering the clamping area. The visual diameter sensor 205 is connected to the control unit of the lifting mechanism. The control unit drives the lifting mechanism to operate according to the detected outer diameter data of the wire, so as to automatically adjust the clamping area distance between the upper wire feeding drum 203 and the lower wire feeding drum 202, as well as the cutting area distance between the annular blades 304 on the upper and lower open drums 303 and 302.

[0042] This design uses a visual diameter sensor to detect the outer diameter of the wire and links it with the lifting mechanism to achieve synchronous adaptive adjustment of the wire feeding clamping distance and the cutting depth, ensuring that wires of different diameters are always in the optimal clamping force and cutting accuracy state.

[0043] In another embodiment, the length of the first conveyor belt group 401 is less than the length of the second conveyor belt group 402. The second conveyor belt group 402 extends beyond the first conveyor belt group 401 on the side near the winding mechanism 500, forming a space that facilitates the gripper 601 of the clamping mechanism 600 to grasp the single wire bundle after it has been separated by the wire pressing and separating mechanism 400.

[0044] To facilitate waste collection, the workbench 100 has a perforated guide groove 101 in the section between the wire pressing and separating mechanism 400 and the winding mechanism 500. The perforated guide groove 101 is used to guide the outer sheath of the wire stripped by the wire pressing and separating mechanism 400 from the outside of the workbench 100.

[0045] To extend the range of motion of the robotic arm, a ring-shaped guide rail 700 is provided along the edge of the workbench 100. The multi-axis robotic arm 603 moves and engages with the ring-shaped guide rail 700 via a movable base. The movable base is provided with a moving drive component that forms a motion coupling with the ring-shaped guide rail 700, which drives the movable base to move circumferentially along the ring-shaped guide rail 700, so that the working range of the multi-axis robotic arm 603 covers the entire circumferential operating area of ​​the workbench 100.

[0046] To avoid interference during winding, the winding mechanism 500 includes two rows of winding shafts 501, which are staggered.

[0047] With the aid of the teachings present in the foregoing description and related drawings, those skilled in the art will conceive of many modifications and other embodiments of the present invention. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used in a general and descriptive sense only and are not intended to be limiting.
