Description

Technical Field

[0001] This utility model relates to the technical field of core wire processing equipment, specifically a servo-controlled core wire meshing mechanism. Background Technology

[0002] In the field of core wire processing, core wire meshing is a key process to ensure product quality. Its meshing accuracy directly affects the conductivity, mechanical strength and service life of the core wire.

[0003] Traditional core wire conveying mechanisms mostly use ordinary motors for driving, resulting in low precision in conveying speed adjustment. This leads to speed fluctuations that cause core wire stretching or accumulation. Furthermore, the fixed guide structure cannot adapt to core wires of different diameters, and wire jamming is prone to occur during feeding, severely affecting conveying stability and processing efficiency. Core wire quality inspection relies heavily on manual sampling, which is inefficient, prone to errors, and difficult to identify defects such as diameter deviations and surface scratches in real time. Substandard raw materials flowing into subsequent processes lead to a decline in finished product quality and increased production costs. At the same time, existing equipment lacks coordinated control in conveying, inspection, straightening, and meshing processes. The parameters of each process cannot be matched in real time, resulting in low automation and requiring a large amount of manual intervention. This not only leads to low processing efficiency but also makes it easy for human error to affect the consistency of finished products. Utility Model Content

[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 4 According to an embodiment of the present utility model, a technical solution is provided: a servo-controlled core wire meshing mechanism, including: a base box 1, a detection component, a straightening component and a meshing component are connected sequentially from left to right on the surface of the base box 1, and the left end of the base box 1 is also connected to a conveying component; the meshing component includes a fixed frame 5, the upper end of the fixed frame 5 is connected to an upper meshing roller 9 through a lifting component, and the lower end of the fixed frame 5 is connected to a lower meshing roller 8.

[0017] The conveying assembly with the above structure stably transports the core wires to be processed (such as cable cores, metal wires, etc.) to the subsequent workstation. The detection assembly is connected to the right side of the conveying assembly. Its core function is to perform pre-processing detection on the conveyed core wires. It can integrate devices such as diameter sensors and surface defect detectors to identify problems such as core wire diameter deviation and surface scratches in real time, and promptly trigger warnings or stop commands to eliminate the impact of unqualified raw materials on subsequent processes from the source. The straightening assembly is located between the detection assembly and the meshing assembly, and adopts a multi-roller cooperative structure, driven by a servo motor. The bidirectional screw adjusts the roller spacing to accommodate core wires of different diameters. When the core wire passes through the roller gap, the squeezing and guiding action of the rollers eliminates bending deformation, providing raw materials with straightness that meet the standards for subsequent meshing processes and avoiding meshing misalignment caused by core wire bending. The fixed frame 5 provides an installation benchmark for the overall structure, ensuring the positioning accuracy of the rollers. The lifting component is controlled by a servo system, which can precisely adjust the height of the upper meshing roller 9 to achieve micron-level control of the roller gap. The upper and lower meshing rollers 8 are driven by a servo to rotate synchronously, and the core wire is shaped, merged, or fixed through the meshing action of the gear teeth.

[0018] In this embodiment, the lifting assembly includes a telescopic cylinder 6, a lifting plate 12, a slide groove 10, and a slider 11. The telescopic cylinder 6 is connected to the top of the fixed frame 5, and its output end passes through the fixed frame 5 and is connected to the lifting plate 12 through the connecting block 13. Slides 11 are connected to both sides of the lifting plate 12, and the two slides 11 are connected to the upper meshing roller 9. The fixed frame 5 has slide grooves 10 on both sides corresponding to the slides 11.

[0019] When it is necessary to adjust the gap between the upper and lower meshing rollers 8, the servo system sends a control signal to the telescopic cylinder 6. The cylinder piston rod extends or retracts, driving the lifting plate 12 to move through the connecting block 13. The slider 11 slides synchronously in the slide groove 10, limiting the lateral displacement of the lifting plate 12 and ensuring that the upper meshing roller 9 moves only in the vertical direction, ultimately achieving precise control of the roller gap.

[0020] The conveying assembly includes a support frame 2, with multiple conveying rollers 3 connected to the surface of the support frame 2. The multiple conveying rollers 3 are connected to an external motor. The support frame 2 is also connected to a guide plate 4. Four guide plates 4 are provided, and a guide channel is formed between two guide plates 4. One end of the guide channel is open.

[0021] The support frame 2 is a metal frame structure with multiple conveying rollers 3 arranged parallel to the core wire conveying direction on its surface (the roller surface is covered with a rubber anti-slip layer to increase friction with the core wire). One end of each conveying roller 3 is connected to the output shaft of an external servo motor via a coupling. The motor can precisely adjust the speed of the conveying rollers 3 according to the speed requirements of subsequent processes, ensuring that the core wire is conveyed smoothly at a constant speed, avoiding core wire stretching or accumulation due to speed fluctuations. Four guide plates 4 (made of transparent acrylic material, for easy observation of the core wire conveying status) are symmetrically fixed on the surface of the support frame 2 at the inlet end and middle of the conveying rollers 3. Two guide plates 4 are arranged in a group and symmetrically distributed on both sides of the core wire conveying path. A continuous guide channel is formed between the two groups of guide plates 4 (the channel width can be finely adjusted by bolts according to the core wire diameter). The entrance end of the guide channel is designed to be open, so that the core wire to be processed can enter the channel quickly and smoothly, avoiding the wire from getting stuck at the entrance. The core wire to be processed enters from the open end of the guide channel and enters the channel under the guidance of the trumpet-shaped entrance. The external servo motor drives the conveying roller 3 to rotate, and the friction between the roller and the core wire drives the core wire to move stably along the guide channel, and finally accurately feeds the core wire into the detection component.

[0022] The straightening assembly includes a base frame 14, with two side plates 17 connected to the top of the base frame 14. Multiple straightening rollers 16 are connected to the opposite sides of the two side plates 17. A drive motor 7 is also provided at the bottom of the base frame 14. A double-ended lead screw is connected to the output end of the drive motor 7. The bottom end of the side plate 17 passes through the base frame 14 and is threadedly connected to the double-ended lead screw. The detection assembly includes a detector 15, which is connected above the straightening assembly.

[0023] Based on the core wire diameter parameters, the servo system controls the drive motor 7 to rotate, which in turn moves the two side plates 17 via a double-headed lead screw, adjusting the spacing of the straightening rollers 16 to the appropriate size. After the core wire enters the straightening assembly, it passes through the horizontal and vertical straightening rollers 16 in sequence. Under the squeezing and guiding action of the rollers, the bent parts are gradually corrected, and finally enter the meshing assembly in a straight state. The detector 15 is fixed above the straightening assembly by the bracket 2, with the detection probe pointing vertically downwards directly above the core wire conveying path, and can collect the core wire diameter data and surface image information in real time. The detector 15 is connected to the servo system via a data cable, and the detection data can be transmitted to the control system in real time. When the core wire enters the detection area from the conveying assembly, the detector 15 starts the detection program, measures the core wire diameter in real time, and identifies whether there are scratches, dents, or other defects on the surface. If the detected diameter deviation exceeds the preset range or there are defects on the surface, the detector 15 immediately sends a signal to the servo system. The system can trigger an alarm device (such as an audible and visual alarm) according to preset instructions, or control the conveying assembly and meshing assembly to stop operating, so that the staff can handle the situation in time.

[0024] Working principle: During operation, the core wire to be processed first enters from the opening end of the guide channel of the conveying component. Guided by the guide plate 4, it enters the channel. The external servo motor drives the conveying roller 3, which is covered with an anti-slip layer, to rotate. The friction force drives the core wire to be conveyed smoothly at a constant speed and accurately fed into the detection component. The detector 15 of the detection component collects the core wire diameter data and surface image information in real time, and identifies problems such as diameter deviation and scratches. If a non-conforming condition is detected, a signal is immediately sent to the servo system. The system can trigger an alarm or control the equipment to stop running for timely handling. The servo system controls the drive motor 7 of the straightening assembly to rotate according to the core wire diameter parameter. The double-headed lead screw drives the side plate 17 to move, adjusting the spacing of the straightening rollers 16 to the appropriate size. After the core wire enters, it is squeezed and guided by the horizontal and vertical straightening rollers 16, and the bent parts are corrected, entering the meshing assembly in a straight state. In the meshing assembly, the servo system sends a control signal to the telescopic cylinder 6 of the lifting assembly, driving the lifting plate 12 to move the upper meshing roller 9 vertically along the slide 10, realizing micron-level precise control of the roller gap. The upper and lower meshing rollers 8 rotate synchronously under the servo drive, and complete the shaping, merging or shaping of the core wire by means of the gear meshing action. The entire process is achieved through the precise coordination of each link by the servo system, ensuring processing quality and efficiency.
