A communication cable end processing apparatus

Abstract

This invention discloses a communication cable end-processing device, belonging to the technical field of communication cable processing equipment. It includes a frame, a material guiding mechanism, and a stripping and pressing mechanism. One side of the frame has an inlet port, and the other side has an inclined unloading plate. By setting the material guiding mechanism and the stripping and pressing mechanism on the frame, the moving part drives the cutting and pressing components to move obliquely along the guide rods via two symmetrically arranged sliding rods. The cutting blades on both sides complete the cutting and stripping of the cable end, achieving automatic cutting and collection of the outer sheath at the crimping position of the communication cable end. During the cutting process, all internal wiring of the cable is automatically crimped in a single pass, avoiding tearing of the end sheath caused by individual crimping processes, and also preventing damage to the already crimped cable joints.

Description

Technical Field

[0001] The present invention relates to the technical field of communication cable processing equipment, and particularly relates to a communication cable end processing equipment. Background Art

[0002] A communication cable consists of a cable core formed by multiple mutually insulated internal wires, and an outer skin with a sealed sheath on the outside. It has a relatively wide transmission bandwidth, a large communication capacity, and is less affected by external interference. During the press-fitting process of the end joint, the prior art often first cuts the outer skin of the end, and then uses semi-automatic equipment to complete the press-fitting of each internal core wire one by one.

[0003] However, in the long-term application process of the prior art, it is found that there are still certain drawbacks: First, the two processes of cable cutting and press-fitting are carried out separately, resulting in oxidation and other phenomena of the ends of the internal core wires during the long-term transportation process, and poor contact after press-fitting the external joints affects signal transmission; Second, after cutting the outer skin, press-fitting the joints of each internal core wire one by one. Since the protruding length of the inner core wire is short, a slight lateral pull is likely to cause the corresponding outer skin to crack. And because the internal core wire itself has a certain flexibility, the internal core wires that have been press-fitted often reset to the fitting position of adjacent core wires during the press-fitting process, resulting in damage to the cable joints after press-fitting. Summary of the Invention

[0004] The purpose of the present invention is to provide a communication cable end processing equipment to solve the above-mentioned defects in the prior art.

[0005] A communication cable end processing equipment includes a frame, a feeding mechanism, and a wire stripping and press-fitting mechanism. An inlet port is provided on one side of the frame, and an inclined discharge plate is arranged on the other side of the frame. The feeding mechanism is installed inside the frame and is used for bidirectional guiding of the communication cable for feeding and discharging. The wire stripping and press-fitting mechanism is installed on the frame and is used for removing the skin of the end of the communication cable and press-fitting joints to the internal cables.

[0006] Preferably, the feeding mechanism includes a "T-shaped" mounting frame, a rotating frame, and a tension spring. The mounting frame is fixedly arranged on the frame. A fixed feeding channel is fixedly connected to one side of the mounting frame. An avoidance hole is provided on the mounting frame. The rotating frame is hinged in the avoidance hole. The tension spring is connected between the side end of the rotating frame and the mounting frame. A movable feeding channel is fixedly connected to the lower end of the rotating frame. A plurality of evenly distributed rollers are installed on the movable feeding channel.

[0007] Preferably, the wire stripping and pressing mechanism includes a drive motor, guide rods, cutting and pressing components, and a moving part. The drive motor is mounted on the side of the frame, and a lead screw is mounted on the output end of the drive motor. The other end of the lead screw is rotatably mounted on the inner wall of the other side of the frame. A slider is threaded onto the lead screw. The upper end of the slider is slidably mounted on the lower end of the mounting bracket. An arc-shaped abutment is rotatably mounted on the side end of the slider via a torsion spring. Several evenly distributed arc-shaped suction cups are mounted on the lower end of the slider. The guide rod has two... The components are symmetrically fixed inside the frame. The cutting and pressing components are slidably mounted on the guide rod. A cutting blade is detachably mounted on the cutting and pressing components. An extrusion groove is opened on the side end of the cutting and pressing components. A connector feeder is installed on the upper end of the cutting and pressing components. A slide rod is rotatably mounted on the upper end of the cutting and pressing components. The lower part of the moving part is threaded onto the lead screw. The upper part of the moving part has an annular structure and is slidably connected to the slide rod. The two sides of the moving part are also slidably mounted on the inner wall of the frame. A contact is also installed on the moving part.

[0008] Preferably, the lead screw is a non-fully threaded lead screw, and the position of the lead screw near the moving part is a smooth rod structure.

[0009] Preferably, the side of the arc-shaped abutment away from the feed port is a smooth arc shape, and the arc-shaped abutment cooperates with the side end of the movable guide channel in the horizontal direction.

[0010] The advantages of this invention are as follows: By setting a material guiding mechanism and a wire stripping and pressing mechanism on the frame, the output end of the drive motor drives the lead screw to rotate, and with the suction force of the arc-shaped suction cup, the communication cable completes the positioning and guiding feeding under the combined action of the rollers on the fixed guide channel and the movable guide channel. By setting a moving part and a slider on the lead screw with a non-fully threaded structure, the moving part drives the cutting and pressing parts to move towards each other and obliquely along the guide rod through two symmetrically arranged sliding rods. The cutting heads on both sides complete the cutting and stripping of the cable end, realizing the automatic cutting and collection of the outer sheath at the crimping position of the communication cable end.

[0011] During the cutting process, as the moving part moves further on the lead screw, the cutting and pressing parts rotate in the reversing section of the guide rod, causing the extrusion grooves on the two cutting and pressing parts to engage and abut against each other. This allows the cable connectors provided by the connector feeder to complete the automatic pressing operation as they approach each other, achieving single-pass automated connector pressing for all internal wiring of the cable. This avoids tearing of the outer sheath of the end during the individual pressing process and also prevents damage to the already pressed cable connectors. Attached Figure Description

Specific embodiments

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] As Figures 1 to 4 shown, a communication cable end processing device includes a frame 1, a material guiding mechanism 2 and a wire stripping and pressing mechanism 3. An inlet port 4 is opened on one side of the frame 1, and an inclined discharging plate 5 is arranged on the other side of the frame 1. The material guiding mechanism 2 is installed in the frame 1 and is used for bidirectional guiding of the communication cable for feeding and discharging. The wire stripping and pressing mechanism 3 is installed on the frame 1 and is used for peeling the end of the communication cable and pressing a connector on the internal cable.

[0019] In this embodiment, the material guiding mechanism 2 includes a "T-shaped" mounting frame 21, a rotating frame 22 and a tension spring 23. The mounting frame 21 is fixedly arranged on the frame 1. A fixed material guiding channel 24 is fixedly connected to one side of the mounting frame 21. An avoidance hole 25 is opened on the mounting frame 21. The rotating frame 22 is hinged in the avoidance hole 25. The tension spring 23 is connected between the side end of the rotating frame 22 and the mounting frame 21. A movable material guiding channel 26 is fixedly connected to the lower end of the rotating frame 22. A plurality of evenly distributed rollers 27 are installed on the movable material guiding channel 26.

[0020] In this embodiment, the wire stripping and pressing mechanism 3 includes a drive motor 301, a guide rod 302, a cutting and pressing component 303, and a moving part 304. The drive motor 301 is mounted on the side of the frame 1, and a lead screw 305 is mounted on the output end of the drive motor 301. The other end of the lead screw 305 is rotatably mounted on the inner wall of the other side of the frame 1. A slider 306 is threaded onto the lead screw 305. The upper end of the slider 306 is slidably mounted on the lower end of the mounting bracket 21. An arc-shaped abutment 307 is rotatably mounted on the side end of the slider 306 via a torsion spring. Several evenly distributed arc-shaped suction cups 308 are mounted on the lower end of the slider 306. The guide rod 302 has... Two components are symmetrically fixed inside the frame 1. The cutting and pressing component 303 is slidably mounted on the guide rod 302. A cutting blade 309 is detachably mounted on the cutting and pressing component 303. An extrusion groove 310 is opened on the side end of the cutting and pressing component 303. A connector feeder 311 is installed on the upper end of the cutting and pressing component 303. A slide rod 312 is rotatably mounted on the upper end of the cutting and pressing component 303. The lower part of the moving part 304 is threaded onto the lead screw 305. The upper part of the moving part 304 has a ring structure and is slidably connected to the slide rod 312. The two sides of the moving part 304 are also slidably mounted on the inner wall of the frame 1. A contact 313 is also installed on the moving part 304.

[0021] It should be noted that the drive motor 301 is a servo motor, which adjusts its own speed according to the thickness of the communication cable sheath to prevent damage to the internal wiring of the cable during the cutting process. The arc-shaped suction cup 308 matches the outer edge of the communication cable sheath.

[0022] In this embodiment, the lead screw 305 is a non-fully threaded lead screw 305. The position of the lead screw 305 near the moving part 304 is a smooth rod structure. When the slider 306 is not in contact with the contact 313, the moving part 304 is in the smooth rod structure of the lead screw 305 and does not move. The side of the arc-shaped abutment block 307 away from the feed port 4 is a smooth arc surface. The arc-shaped abutment block 307 cooperates with the side end of the movable guide channel 26 in the horizontal direction, so that the arc-shaped abutment block 307 extends into the slider 306 during the forward movement, and the arc-shaped abutment block 307 extends out of the slider 306 during the return movement and pushes the rotating frame 22, so that the cable after the cable connector is pressed can be discharged smoothly.

[0023] Working process and principle: Before use, the cutting head 309 matching the communication cable to be processed is first installed on the cutting and pressing part 303. Then, the communication cable to be processed is placed at the port of 4 and pushed to the bottom of the arc suction cup 308. After the arc suction cup 308 is activated to attract the cable, the drive motor 301 is started so that its output end drives the lead screw 305 to rotate, causing the slider 306 to slide at the lower end of the mounting frame 21. During this process, under the tension of the tension spring 23, the lower end of the rotating frame 22 deflects and moves closer to the fixed guide channel 24, so that the roller 27 on the movable guide channel 26 cooperates with the fixed guide channel 24 on the other side to form a positioning guide for the cable. The smooth transition side of the arc abutment 307 is hidden in the slider 306 after contacting the rotating frame 22. When the arc suction cup 308 moves with the cable connector to the fixed guide channel, When the slider 306 is at the end of the lead screw 305, the slider 306 is in the bare rod position and contacts the contact 313 and pushes it, pushing the moving part 304 into another threaded section of the lead screw 305. The moving part 304 drives the cutting and pressing parts 303 to move towards each other and obliquely along the guide rod 302 via two symmetrically arranged sliding rods 312. The cutting blades 309 on both sides complete the cutting and stripping of the cable end to expose the inner core wire of the connector to be pressed. The cut cable sheath is discharged from the outside of the obliquely arranged 5. As the moving part 304 moves further on the lead screw 305, the cutting and pressing parts 303 rotate in the reversing section of the guide rod 302, so that the extrusion grooves 310 on the two cutting and pressing parts 303 cooperate and abut against each other, so that the cable connector provided by the connector feeder 311 completes the pressing operation during the approach process.

[0024] After the cutting, peeling and pressing process is completed, the drive motor 301 is restarted to make its output end rotate in the opposite direction, that is, to perform the above operation in reverse. During this process, since the non-arc section of the arc-shaped abutment 307 cooperates with the side end of the rotating frame 22, the arc-shaped abutment 307 will not be submerged in the slider 306, and will have a pushing and separating effect on the rotating frame 22, thereby allowing the cable end with the pressed connector to be smoothly discharged from 4 to complete the unloading.

[0025] Based on the above, the present invention sets a material guiding mechanism 2 and a wire stripping and pressing mechanism 3 on the frame 1. The output end of the drive motor 301 drives the lead screw 305 to rotate. With the suction force of the arc-shaped suction cup 308, the communication cable completes the positioning and guiding feeding under the joint action of the rollers 27 on the fixed guide channel 24 and the movable guide channel 26. By setting a moving part 304 and a slider 306 on the lead screw 305 with a non-fully threaded structure, the moving part 304 drives the cutting and pressing part 303 to move towards each other and obliquely along the guide rod 302 through two symmetrically arranged sliding rods 312. The cutting heads 309 on both sides complete the cutting and stripping of the cable end, realizing the automatic cutting and collection of the outer sheath at the crimping position of the communication cable end.

[0026] During the cutting process, as the moving part 304 moves further on the lead screw 305, the cutting pressing part 303 rotates in the reversing section of the guide rod 302, causing the extrusion grooves 310 on the two cutting pressing parts 303 to engage and abut against each other. This allows the cable connectors provided by the connector feeder 311 to complete the automatic pressing operation as they approach each other, achieving single-pass automated connector pressing for all internal wiring of the cable. This avoids tearing of the outer sheath of the end during the individual pressing process and also prevents damage to the already pressed cable connectors.

[0027] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or equivalent to the scope of this invention are included in this invention.
