Description

Technical Field

[0001] This invention relates to the field of coaxial cable welding equipment technology, specifically a portable coaxial cable joint welding tool. Background Technology

[0002] In accordance with the State Grid Corporation's requirements for building a smart grid and with the development of current automation technology, the increasingly complex automation master stations and substations have placed higher demands on the commissioning and daily operation and maintenance of new equipment. This has led to insufficient commissioning time in the channel and three-level data network commissioning processes. In particular, the welding of coaxial cable joints consumes a significant amount of time, and the phenomenon of incomplete welding is very common, affecting communication performance and further increasing the workload of channel commissioning. The daily maintenance of the welded joints is also quite cumbersome. Therefore, the automation profession needs a device to solve these current problems.

[0003] Currently, there are two types of welding connectors for data leased lines: BNC and L9-J plugs. Their internal structures are similar. Due to the small size of the welding head, welding coaxial cable connectors is still done manually. Manual welding requires one hand to hold the fiber core while the other hand holds the soldering iron. However, because the coaxial cable fiber core is thin, it is difficult to hold it firmly when soldering with a soldering iron, easily causing burns and resulting in problems such as cold solder joints and short circuits at the 2M connector. Therefore, designing a portable coaxial cable connector welding tool is essential. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a portable coaxial cable joint welding tool that automatically welds cable joints. While ensuring the welding quality of cable cores, it optimizes the inconvenience of coaxial cable joint welding caused by complex working environments, improves work efficiency, and simplifies the workflow.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable coaxial cable connector welding tool, comprising a base, a central control cabinet mounted on one side of the top of the base, a control board mounted on one side of the central control cabinet, a back plate mounted on the side of the central control cabinet, a cable connector positioning component mounted on one side of the base located on the central control cabinet, a cable positioning component mounted on one side of the cable connector positioning component, a Z-axis lead screw drive component mounted on the back plate at the center of the cable connector positioning component and the cable positioning component, a positioning platform fixed on the Z-axis lead screw drive component, a welding head fixed on the positioning platform, a feed pipe fixed to the bottom of the positioning platform mounted on one side of the welding head, a driven wheel assembly and a driving wheel symmetrically mounted on the top of the feed pipe, and a welding wire roll fixed on the side of the welding head on the positioning platform via a material roller.

[0006] Preferably, the driven wheel assembly includes a pressure groove, a pressure rod, a spring, a receiver, and a driven wheel. The surface of the positioning platform is provided with a pressure groove, and a pressure rod is connected inside the pressure groove. The surface of the pressure rod is movably connected to the driven wheel, and the driven wheel is simultaneously movably connected inside the pressure groove. A spring is sleeved on the surface of the pressure rod. The surface of the positioning platform is provided with a receiver, and a transmitter is connected to the surface of the driven wheel. The receiver is electrically connected to a control board, and the control board is electrically connected to the driving wheel.

[0007] Preferably, the cable positioning component includes a positioning ring, an internal threaded seat, an external threaded rod, and a pressure plate;

[0008] The positioning ring is fixed to the top of the base. An internal threaded seat is provided at the center of the top of the positioning ring. An external threaded rod is screwed and fixed inside the internal threaded seat. A pressure plate is rotatably connected to the bottom end of the external threaded rod.

[0009] Preferably, a slide rod is installed on the top side of the pressure plate, and the slide rod is slidably connected inside the slide hole on the top side of the positioning ring.

[0010] Preferably, the cable connector positioning component includes a base plate fixed to the top of the base, the base plate having symmetrically opened grooves, a slider being slidably connected inside the grooves, and racks being staggered at the bottom of the two sliders, a gear being installed at the center of the bottom of the base and meshing with the racks, the gear being fixed to the output end of the stepper motor, the stepper motor being fixed to the bottom of the base by a motor frame, and a clamping plate being installed on the top of the slider.

[0011] Preferably, the slider has a through hole, and the rack is slidably connected inside the through hole.

[0012] Preferably, a pressure switch is installed at the center of the inner wall of the clamping plate, and the pressure switch is electrically connected to the stepper motor.

[0013] Preferably, universal self-locking wheels are installed at the four corners of the bottom of the base.

[0014] Preferably, the positioning ring includes an upper ring and a lower ring. A rotating block is connected to one side of the upper ring, and a fastening groove is provided on the other side of the upper ring. A rotating seat is provided on one side of the lower ring, and a fastening shaft is provided on the other side of the lower ring. A fastening bolt is movably connected to the surface of the fastening shaft, and a nut is threaded onto the surface of the fastening bolt. The fastening bolt is located in the fastening groove. A movable shaft is connected inside the rotating seat, and the rotating block is movably connected to the surface of the movable shaft.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. By setting up automatic cable joint welding, the welding quality of cable cores is ensured, while optimizing the inconvenience of coaxial cable joint welding caused by complex working environment, improving work efficiency and simplifying the workflow.

[0017] 2. By setting a transmitter on the passive wheel, when the passive wheel rotates one revolution or a set number of revolutions, the electrical signal emitted by the transmitter is received by the receiver. The receiver sends a signal to the control board, which controls the active wheel to stop working. After the active wheel stops, the welding wire will no longer be output, thus making it convenient to control the length of the welding wire.

[0018] 3. Pass the coaxial cable through the positioning ring and rotate the external threaded rod. Due to the limiting effect of the sliding rod and sliding hole, the pressure plate moves downward inside the positioning ring and presses against the top of the coaxial cable, ensuring the stability of the coaxial cable and making installation and disassembly convenient.

[0019] 4. Place the cable connector between the two clamps, the stepper motor works, drives the gear to rotate, thereby driving the rack to move, so that the two clamps move closer to each other, clamping the cable connector, with good clamping stability;

[0020] 5. The pressure switch is activated when the two clamps tighten the cable connector, causing the stepper motor to stop working, thus achieving a linkage control function.

[0021] 6. By setting a spring, the passive wheel is always in close contact with the welding wire under the action of the spring's own elastic force, which makes it easier for the active wheel to drive the welding wire better. At the same time, because the passive wheel is always in close contact with the welding wire, the welding wire will not be too much or too little, thus avoiding welding defects.

[0022] 7. By dividing the positioning ring into an upper ring and a lower ring, it is convenient for the coaxial cable to enter the positioning ring. At the same time, after welding is completed, the upper ring is opened from the lower ring, which makes it easy for the welded joint to pass through the positioning ring, thereby avoiding damage to the joint or positioning ring due to scraping when the joint passes through the positioning ring.

Therefore, they should not be construed as limitations on this invention.

[0034] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. Example

[0035] Depend on Figure 1, Figure 2 , Figure 8 The present invention provides the following technical solution: a portable coaxial cable connector welding tool, comprising a base 1, a central control cabinet 3 mounted on one side of the top of the base 1, a control board 4 mounted on one side of the central control cabinet 3, a back plate 5 mounted on the side of the central control cabinet 3, a cable connector positioning component 6 mounted on one side of the central control cabinet 3 on the base 1, a cable positioning component 7 mounted on one side of the cable connector positioning component 6, a Z-axis lead screw drive component 8 mounted on the back plate 5 at the center of the cable connector positioning component 6 and the cable positioning component 7, a positioning platform 9 fixed on the Z-axis lead screw drive component 8, a welding head 10 fixed on the positioning platform 9, a feed pipe 15 fixed to the bottom of the positioning platform 9 mounted on one side of the welding head 10, a driven wheel assembly 11 and a driving wheel 14 symmetrically mounted on the top of the feed pipe 15, and a welding wire roll fixed on the positioning platform 9 to the side of the welding head 10 via a material roller 12. 13. Fix the cable connector onto the cable connector positioning piece 6. Then, strip the appropriate length of the center core and shielding layer from the coaxial cable as required. Pass the coaxial cable through the cable positioning piece 7 and fix it inside the cable connector. Secure the coaxial cable with the cable positioning piece 7. Use the control board 4 to make the Z-axis lead screw drive 8, welding head 10 and drive wheel 14 work synchronously. The drive wheel 14 works to drive the welding wire to move inside the feed tube 15, so that the welding wire moves to directly below the welding head 10. Then, the Z-axis lead screw drive 8 moves downward, and the welding wire located below the welding head 10 is melted and welded to the connection between the cable connector and the coaxial cable through the welding head 10. The cable connector can be automatically welded. While ensuring the welding quality of the cable core, it optimizes the inconvenience of welding coaxial cable connectors caused by complex working environment, improves work efficiency and simplifies the workflow.

[0036] Preferably, the driven wheel assembly 11 includes a pressure groove 1101, a pressure rod 1102, a spring 1103, a receiver 1104, and a driven wheel 1105. The surface of the positioning platform 9 is provided with a pressure groove 1101, and a pressure rod 1102 is connected inside the pressure groove 1101. The surface of the pressure rod 1102 is movably connected to the driven wheel 1105, and the driven wheel 1105 is simultaneously movably connected inside the pressure groove 1101. The surface of the pressure rod 1102 is fitted with a spring 1103. The surface of the positioning platform 9 is provided with a receiver 1104, and a transmitter 16 is connected to the surface of the driven wheel 1105. The receiver 1104 is electrically connected to the control board 4, and the control board 4 is electrically connected to the driving wheel 14. By setting the spring 1103, the driven wheel 1105 is always in close contact with the welding wire under the action of the spring 1103's own elastic force, thereby facilitating the driving wheel 14 to better drive the welding wire. At the same time, since the driven wheel 1105 is always in close contact with the welding wire, the welding wire will not be over- or under-protruded, thereby avoiding welding defects.

[0037] Preferably, the base 1 is equipped with universal self-locking wheels 2 at the four corners of its bottom, which makes it easy to move and position on the ground. Example

[0038] Reference Figures 1 to 4 As another preferred embodiment, the difference from Embodiment 1 is that the cable positioning component 7 includes a positioning ring 17, an internal thread seat 18, an external thread rod 19, and a pressure plate 20. The positioning ring 17 is fixed to the top of the base 1. An internal thread seat 18 is provided at the center of the top of the positioning ring 17. An external thread rod 19 is screwed and fixed inside the internal thread seat 18. The pressure plate 20 is rotatably connected to the bottom end of the external thread rod 19. When the coaxial cable is passed through the positioning ring 17 and the external thread rod 19 is rotated, the pressure plate 20 moves downward inside the positioning ring 17 due to the limiting effect of the sliding rod 21 and the sliding hole 22, pressing against the top of the coaxial cable to ensure the stability of the coaxial cable fixation and facilitate installation and disassembly.

[0039] Preferably, the positioning ring 17 includes an upper ring 1701 and a lower ring 1702. A rotating block 1704 is connected to one side of the upper ring 1701, and a fastening groove 1709 is provided on the other side of the upper ring 1701. A rotating seat 1703 is provided on one side of the lower ring 1702, and a fastening shaft 1708 is provided on the other side of the lower ring 1702. A fastening bolt 1706 is movably connected to the surface of the fastening shaft 1708, and a nut 1707 is threaded onto the surface of the fastening bolt 1706. The fastening bolt 1706 is located in the fastening groove 1709. Inside, a movable shaft 1705 is connected to the rotating seat 1703, and a rotating block 1704 is movably connected to the surface of the movable shaft 1705. By dividing the positioning ring 17 into an upper ring 1701 and a lower ring 1702, it is convenient for the coaxial cable to enter the positioning ring 17. At the same time, after welding is completed, the upper ring 1701 is opened from the lower ring 1702, so that the welded joint can pass through the positioning ring 17, thereby avoiding damage to the joint or the positioning ring 17 due to scraping when the joint passes through the positioning ring 17.

[0040] Preferably, a slide rod 21 is installed on the top side of the tablet 20, and the slide rod 21 is slidably connected inside the slide hole 22 on the top side of the positioning ring 17. Example

[0041] Reference Figure 1 , Figure 5 and Figure 6As another preferred embodiment, the difference from embodiment one is that the cable connector positioning component 6 includes a base plate 23 fixed to the top of the base 1. The base plate 23 has symmetrically opened grooves 24. A slider 27 is slidably connected inside the groove 24, and racks 32 are staggered at the bottom of the two sliders 27. A gear 30 that meshes with the racks 32 is installed at the center of the bottom of the base 1. The gear 30 is fixed to the output end of the stepper motor 31. The stepper motor 31 is fixed to the bottom of the base 1 through the motor frame 28. A clamping plate 25 is installed on the top of the slider 27. When the cable connector is placed between the two clamping plates 25, the stepper motor 31 works, drives the gear 30 to rotate, thereby driving the racks 32 to move, so that the two clamping plates 25 move closer to each other and clamp the cable connector, resulting in good clamping stability.

[0042] Preferably, the slider 27 has a through hole 29, and the rack 32 is slidably connected inside the through hole 29 to avoid the movement of the rack 32 affecting the movement of the slider 27.

[0043] Preferably, a pressure switch 26 is installed at the center of the inner wall of the clamping plate 25. The pressure switch 26 is electrically connected to the stepper motor 31. When the two clamping plates 25 clamp the cable connector, the pressure switch 26 will be activated, causing the stepper motor 31 to stop working, thus playing a linkage control role.

[0044] Working principle:

[0045] The cable connector is fixed on the cable connector positioning piece 6. Then, the coaxial cable is stripped to the appropriate length of the center core and shielding layer. The coaxial cable is passed through the cable positioning piece 7 and fixed inside the cable connector. The coaxial cable is then fixed by the cable positioning piece 7. The control board 4 is used to make the Z-axis lead screw drive 8, the welding head 10 and the drive wheel 14 work synchronously. The drive wheel 14 works to drive the welding wire to move inside the feed tube 15, so that the welding wire moves to the underside of the welding head 10. Then, the Z-axis lead screw drive 8 moves downward, and the welding wire located below the welding head 10 is melted and welded to the connection between the cable connector and the coaxial cable through the welding head 10. The cable connector is automatically welded. While ensuring the welding quality of the cable core, it optimizes the inconvenience of welding coaxial cable connectors caused by complex working environment, improves work efficiency and simplifies the workflow.
