Description

An indentation device for audio cable processing Technical Field

[0001] This utility model relates to the field of cable indentation technology, and in particular to an indentation device for audio cable processing. Background Technology

[0002] Audio cables require indentation during processing. The main purpose of indentation is for marking and identification. However, existing indentation machines are difficult to indent cables with a large diameter range and need to be improved.

[0003] Chinese patent CN216749475U discloses an indentation device for processing audio cables for audio equipment. The indentation wheel indents the audio cable with pressure. At the same time, during the indentation process, an electric slide rail drives an electric hydraulic push rod and the indentation wheel to move through a slider. The indentation wheel indents the audio cable during the movement, thus allowing the indentation depth and distance of the audio cable to be adjusted.

[0004] However, the device still has shortcomings: it needs to perform the creasing process on the audio cable while it is stopped from being wound up, which makes it take longer for long audio cables to complete the fixed-distance creasing, resulting in low creasing efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an indentation device for audio cable processing.

[0006] The technical solution of this utility model is: an indentation device for audio cable processing, including a base, a guide frame on the base, a guide wheel with a guide groove at each end of the guide frame, and two guide rollers between the two guide wheels on the guide frame;

[0007] The belt drives two guide rollers, and the guide frame is equipped with a support plate to support the heavy section of the belt.

[0008] The limiting mechanism is set on the support plate. In the working state, the limiting mechanism clamps and limits the audio wire falling on the belt from both sides without affecting the movement of the audio wire along the conveying direction of the belt.

[0009] A positioning component is mounted on the guide frame and measures the distance the audio cable moves when in operation.

[0010] And an indentation mechanism, which is set on the guide frame, and the indentation mechanism performs fixed-distance indentation on the audio line according to the positioning component.

[0011] Preferably, the cross-section of the guide groove along the radial direction of the guide wheel is V-shaped, and the weight-bearing section of the belt is not lower than that of the guide wheel.

[0012] Preferably, the limiting mechanism includes a carriage and a drive assembly A. Two carriages are symmetrically arranged on the support plate, and the two carriages are located on both sides of the belt. Each carriage has a mounting plate at both ends, and a limiting wheel is rotatably arranged on each mounting plate. The axis of the limiting wheel is perpendicular to the upper end face of the support plate, and the limiting wheel slides in contact with the upper surface of the weight-bearing section of the belt. Several flexible annular anti-slip pads are evenly spaced on the arc surface of the limiting wheel. The drive assembly A is arranged on the support plate and drives the two carriages to move closer or further away synchronously.

[0013] Preferably, the mounting plate is movably connected to the carriage, and a pressure sensor is installed on the carriage. The detection end of the pressure sensor contacts the mounting plate. A controller is installed on the base, and the controller is electrically connected to the pressure sensor. The drive assembly A is also electrically connected to the controller.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By setting guide wheels and a belt supported by a support plate on the guide frame, and setting a movable indentation roller, the indentation roller applies pressure to the cable on the belt, completing the indentation operation on the cable sheath while the cable is in motion; by setting a positioning component consisting of a speed sensor and a controller, the speed sensor measures the number of rotations of the guide wheels to determine the moving length of the cable, thus facilitating fixed-length indentation of the cable; by setting two sets of adjustable-gap limit wheels on the support plate, the limit wheels are used to press against the cable from both sides to prevent the cable from deviating or twisting when in contact with the indentation roller.

[0025] Example 1

[0026] As shown in Figures 1-4, the present invention discloses an indentation device for audio cable processing, comprising a base 1, a belt 6, a limiting mechanism, a positioning component, and an indentation mechanism. A guide frame 2 is mounted on the base 1, with a guide wheel 3 having a guide groove 301 at each end of the guide frame 2. Two guide rollers 5 are mounted on the guide frame 2 between the two guide wheels 3. The cross-section of the guide groove 301 along the radial direction of the guide wheel 3 is V-shaped. The belt 6 drives and connects the two guide rollers 5, and a support plate 7 is mounted on the guide frame 2 to support the weight-bearing section of the belt 6, wherein the weight-bearing section of the belt 6 is not lower than the guide wheel 3. The limiting mechanism is set on the support plate 7. The limiting mechanism includes a slide 8 and a drive assembly A12. Two slides 8 are symmetrically arranged on the support plate 7 and slidably connected to it. A guide rod is set on the support plate 7. The guide rod passes through the two slides 8 and is slidably connected to them. The two slides 8 are located on both sides of the belt 6. A mounting plate 9 is set at each end of each slide 8. A limiting wheel 11 is rotatably set on each mounting plate 9. The axis of the limiting wheel 11 is perpendicular to the upper end face of the support plate 7, and the limiting wheel 11 slides in contact with the upper surface of the weight-bearing section of the belt 6. Several flexible annular anti-slip pads are evenly spaced on the arc surface of the limiting wheel 11. The drive assembly A12 includes a motor A and a bidirectional lead screw. The bidirectional lead screw is set on the support plate 7 and rotatably connected to it. The two slides 8 are threadedly connected to the corresponding ends of the bidirectional lead screw. The body of the motor A is set on the support plate 7. The output end of the motor A is connected to the bidirectional lead screw. When the motor A is working, it drives the two slides 8 to move closer or further away synchronously. In operation, the limiting mechanism clamps and limits the audio cable falling on the belt 6 from both sides without affecting the movement of the audio cable along the conveying direction of the belt 6. The mounting plate 9 is movably connected to the carriage 8, and a pressure sensor 10 is installed on the carriage 8. The detection end of the pressure sensor 10 contacts the mounting plate 9. A controller is installed on the base 1, and the controller is electrically connected to the pressure sensor 10. The drive assembly A12 is also electrically connected to the controller. A positioning assembly is installed on the guide frame 2. The positioning assembly includes a speed sensor 4, which measures the rotational speed of one of the guide wheels 3 in operation. The speed sensor 4 is electrically connected to the controller. In operation, the positioning assembly measures the movement distance of the audio cable. The indentation mechanism is mounted on the guide frame 2. The indentation mechanism includes a support 13, an indentation roller 15, and a drive assembly B16. The support 13 is mounted on the guide frame 2, and a movable plate 14 is slidably mounted on the support 13. An ear plate is mounted on the bottom of the movable plate 14, and a pressure sensor is also mounted on the movable plate 14 to monitor the pressure feedback from the ear plate. This pressure sensor is electrically connected to the controller. The indentation roller 15 is rotatably connected to the ear plate and is located directly above the support plate 7. Indentation protrusions are provided on the arc surface of the indentation roller 15. The drive assembly B16 includes, but is not limited to, a hydraulic cylinder. The body of the hydraulic cylinder is mounted on the support 13, and the output end of the hydraulic cylinder is connected to the movable plate 14. The indentation mechanism performs fixed-distance indentation on the audio cable according to the positioning assembly.

[0027] It should be noted that the motors in this embodiment are all servo motors, the speed sensor 4 is a wheel speed sensor, and the controller is a PLC controller.

[0028] In this embodiment, the cable end is unwound from the unwinding device, then pulled around over the two guide wheels 3 and the belt 6, and then fixed on the winding device. At this time, the cable is naturally stuck in the guide groove 301, which can effectively prevent it from shifting laterally during movement. Then, the motor A is started, and the motor A drives the bidirectional lead screw to rotate, so that the two side carriages 8 move closer to each other until the two sets of limit wheels 11 flexibly press against the cable from both sides. The winding device is started, and the cable begins to move and drive the guide wheels 3 to rotate. At this time, the speed sensor 4 measures the number of rotations of the guide wheels 3, thereby measuring the moving distance of the cable. The spacing of the indentation on the cable is preset. When the position of the cable indentation is reached, the hydraulic cylinder presses down the movable plate 14, so that the indentation roller 15 abuts against the surface of the cable. The pressure of the compression is directly obtained by the pressure sensor. During the movement of the cable, the indentation roller 15 is automatically rotated and the belt 6 is driven to run, thereby avoiding the cable from rubbing and scratching the belt 6.

[0029] Example 2

[0030] As shown in Figures 1 and 5, the indentation device for audio cable processing proposed in this utility model, compared with Embodiment 1, has a bracket 17 at each end of the guide frame 2 on the base 1. A spline shaft 18 is rotatably mounted on one side of the bracket 17, and a winding roller 20 is sleeved on the spline shaft 18 and slides along its axial direction. The bracket 17 has a side groove 171 for the lateral movement of the winding roller 20. Two support rollers 21 for supporting the winding roller 20 are symmetrically arranged on the bracket 17, and a drive assembly C19 for driving the spline shaft 18 on one of the brackets 17 is provided. The drive assembly C19 includes, but is not limited to, a motor B, which is a servo motor. The motor B is electrically connected to the controller, the body of the motor B is connected to the bracket 17, and the output end of the motor B is connected to the spline shaft 18 on the bracket 17.

[0031] In this embodiment, the bracket 17 with motor B is a take-up roller bracket. The winding roller 20 on the bracket 17 is used as a take-up roller for audio cables, while the other winding roller 20 is used as an unwinding roller. Since one end of the bracket 17 is in an open state, it is convenient to put the winding roller 20 on the spline shaft 18 or to move it laterally off the spline shaft 18. The support roller 21 supports the guard plates at both ends of the winding roller 20 without affecting its rotation, so as to prevent the spline shaft 18 from being bent.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
