Description

Technical Field

[0001] This utility model belongs to the technical field of cable winding and processing equipment, and particularly relates to a cable winding device for stretching and pressing to straighten the wire. Background Technology

[0002] Existing cable winding equipment typically includes a feeding guide roller, a cable guide roller, and a winding roller arranged sequentially along the conveying direction. The cable is introduced through the feeding guide roller, guided in direction and subjected to a certain tension by the cable guide roller, and finally wound onto the winding roller to form a coil. However, when the cable itself has local bending deformation (such as due to uneven stress during production or transportation), the constant tension applied by the cable guide roller alone is often insufficient to effectively eliminate these bends. During the winding process, the bent parts of the cable are prone to forming bulges on the winding roller or causing gaps between the winding layers, resulting in insufficient overall coil tightness, poor appearance, increased space occupation, and even affecting the smoothness of cable unwinding in subsequent use. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a cable winding device for stretching and pressing, which combines radial stretching and pressing with radial pressing of the pressing wheel to achieve efficient cable straightening and high-density winding.

[0004] Technical solution: To achieve the above objectives, this utility model provides a cable winding device for stretching and straightening, comprising a feeding guide wheel, a cable guide wheel, and a winding wheel arranged sequentially along the conveying direction. The cable guide wheel is arranged radially movable to stretch and straighten the cable by changing the tension path of the cable.

[0005] It also includes a pressure roller, which is parallel to the axis of the cable guide roller and located radially outside it. The pressure roller is radially movable and its surface extends into the guide groove of the cable guide roller by radial movement, thereby pressing and straightening the cable passing through the cable guide roller.

[0006] Furthermore, the system includes a guide rail, which is slidably provided with two sliders. The cable guide wheel and the pressure wheel are respectively connected to the corresponding sliders via their respective axles.

[0007] Furthermore, it includes a stretching drive unit, which is connected to a slider connected to the cable guide wheel for driving the cable guide wheel to move radially.

[0008] Furthermore, it includes a pressure-driving unit, which is connected to a slider connected to the pressure wheel for driving the pressure wheel to move radially.

[0009] Furthermore, the stretching drive and / or the pressing drive is a cylinder or an electric push rod.

[0010] Furthermore, it includes a cable laying drive mechanism, which is drivenly connected to the guide rail and is used to drive the guide rail to reciprocate along a line parallel to the axis of the winding wheel, thereby driving the cable laying guide wheel to move axially to achieve uniform cable laying.

[0011] Furthermore, the cable routing drive mechanism includes a lead screw, a servo motor, a guide rod, and a guide sleeve; the lead screw, driven by the servo motor, is rotatably connected to the frame and threaded through the guide rail; the guide rod is slidably mounted on the frame through the guide sleeve with axial displacement engagement and is fixedly connected to the guide rail.

[0012] Furthermore, it includes a first vision inspection component disposed at the front end of the feeding guide wheel, the first vision inspection component being interlocked with the stretching drive unit via a main controller.

[0013] Furthermore, it includes a second vision inspection component disposed between the feeding guide wheel and the wire guide wheel, the second vision inspection component being interlocked with the wire pressing drive unit via the main controller.

[0014] Beneficial effects: This utility model directly eliminates macroscopic bending deformation of the cable, such as arc deformation, and improves the straightness of the cable by actively adjusting the cable tension path and applying controllable tensile force to the bending section; it uses radial pressure to make the cable fit tightly against the bottom of the cable guide wheel groove, forcibly correcting local minor warping or kinking, and making up for the blind spots of tension correction, which is especially suitable for local shaping of high rigidity cables; tension correction and pressure correction work in sequence, first straightening large curvature deformation through tension, and then finely correcting residual deformation through local pressure, which significantly improves the correction coverage and success rate.

[0016] Figure 2 This is a three-dimensional structural diagram of the feeding guide wheel, the wire guide wheel, the winding wheel, and the corresponding components. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2As shown, a cable winding device for stretching and straightening includes a feeding guide wheel 1, a cable guide wheel 2, and a winding wheel 3 arranged sequentially along the conveying direction. The cable guide wheel 2 is radially movable to stretch and straighten the cable 10 by changing the tension path of the cable 10. By actively adjusting the tension path of the cable 10, a controllable tensile force is applied to the bent section to directly eliminate macroscopic bending deformation of the cable, such as arc deformation, and improve the straightness of the cable.

[0019] This utility model also includes a pressure roller 4, which is parallel to the axis of the cable guide roller 2 and located radially outward therefrom. The pressure roller 4 is radially movable, and its surface extends into the guide groove 20 of the cable guide roller 2 through radial movement, thereby pressing and straightening the cable 10 passing through the cable guide roller 2. Radial pressure is used to force the cable to adhere tightly to the bottom of the guide roller groove, forcibly correcting minor local warping or kinking, and compensating for blind spots in tensile straightening. This is particularly suitable for the local shaping of high-rigidity cables.

[0020] Tension orthodontics and suture orthodontics work sequentially, with tension orthodontics being the primary orthodontic treatment and suture orthodontics being the secondary orthodontic treatment: first, tension is used to straighten large curvature deformations, and then local pressure is used to finely correct residual deformations, significantly improving the orthodontic coverage and success rate.

[0021] This utility model includes a guide rail 5, on which two sliders 50 are slidably mounted. The cable guide wheel 2 and the pressure wheel 4 are respectively connected to the corresponding sliders 50 via their respective axles. This ensures the synchronous stability of the radial movement of the cable guide wheel 2 and the pressure wheel 4, avoiding relative positional deviations that occur when the two wheels move independently.

[0022] This invention includes a tension drive unit 2a, which is driven by a slider 50 connected to the cable guide wheel 2, for driving the cable guide wheel 2 to move radially. It also includes a pressure drive unit 4a, which is driven by a slider 50 connected to the pressure wheel 4, for driving the pressure wheel 4 to move radially. This achieves independent and precise control of the two-wheel straightening actions. Specifically, the tension drive unit 2a can adjust the tension according to the overall bending degree of the cable 10; while the pressure drive unit 4a dynamically adjusts the pressing depth as needed to adapt to different wire diameters and deformation intensities, avoiding overpressure damage to the cable.

[0023] In this invention, the stretching drive unit 2a and / or the pressing drive unit 4a are cylinders or electric push rods.

[0024] This utility model includes a cable laying drive mechanism, which is drivenly connected to the guide rail 5. The mechanism drives the guide rail 5 to reciprocate along a line parallel to the axis of the winding wheel 3, thereby causing the cable laying guide wheel 2 to move axially to achieve uniform cable laying and eliminate interlayer gaps. More specifically, as... Figure 2As shown, the cable routing drive mechanism includes a lead screw 8, a servo motor 9, a guide rod 11, and a guide sleeve 12. The lead screw 8, driven by the servo motor 9, is rotatably connected to the frame 6 and threaded through the guide rail 5. The guide rod 11 is slidably mounted on the frame 6 through the guide sleeve 12 with axial displacement engagement and is fixedly connected to the guide rail 5. The lead screw servo transmission has higher precision.

[0025] like Figure 1 As shown, this utility model includes a first vision detection component 13 disposed at the front end of the feeding guide roller 1. The first vision detection component 13 is interlocked with the tension drive unit 2a through a main controller. The first vision detection component 13 identifies the original bending state of the cable 10 in real time, triggering the tension drive unit 2a to actively intervene, realizing intelligent tension adjustment of detection before correction.

[0026] It also includes a second vision inspection component 14 disposed between the feeding guide roller 1 and the wire guide roller 2. The second vision inspection component 14 is interlocked with the wire pressing drive unit 4a through the main controller. It inspects the shape of the wire after stretching and straightening. If the residual deformation exceeds the standard, it interlocks and starts the wire pressing drive unit 4a, forming a closed-loop quality control of initial inspection, stretching, secondary inspection and wire pressing.

[0027] It is worth noting that the dual detection and interlocking control of this utility model differs from the traditional passive orthodontic mode. It makes judgments and actively executes orthodontics based on feedback from visual detection, which greatly reduces the failure rate.

[0028] Preferably, both the first visual inspection component 13 and the second visual inspection component 14 are industrial cameras.

[0029] It should be clarified that in this utility model, such as Figure 2 As shown, the feeding guide wheel 1 and the wire guide wheel 2 are both grooved wheels, while the pressing wheel 4 is a smooth wheel without grooves. The feeding guide wheel 1, the wire guide wheel 2, and the pressing wheel 4 can all rotate on their respective axles, while the winding wheel 3 is fixedly mounted on its axle. The rotation of the winding wheel 3 is controlled by a drive motor located inside the frame 6.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
