Description

Technical Field

[0001] This invention belongs to the field of shielded cable production technology, specifically relating to a fully automatic anti-surge cable threading device for shielded cable processing. Background Technology

[0002] Shielded cables are cables covered with a wave shield (i.e., a shielding mesh) and are used in applications where high signal shielding effectiveness is required. For example, in equipment such as filters, a large number of interconnecting cables need to be shielded; also, in electromagnetic compatibility testing, shielding effectiveness enhancement, and other testing and rectification processes, it is often necessary to temporarily add a wave shield to the cable.

[0003] For pre-purchased shielded cables, the anti-surge sleeve is pre-installed on the cable and can be used directly. However, for specific application requirements of different equipment, because the cables used often include multiple strands of conductors of different specifications (including the conductor core and insulation layer), it is generally necessary to temporarily or on-site insert the conductors into the anti-surge sleeve to form a shielded cable. This process is generally called anti-surge sleeve insertion.

[0004] For applications requiring temporary or on-site installation of wave shields, the traditional method involves manually threading the wires into the wave shield step by step, which usually requires two or more people working together, resulting in time-consuming, labor-intensive, and inefficient processes. Summary of the Invention

[0005] The purpose of this invention is to provide a fast and efficient fully automatic anti-surge cable threading device for processing shielded cables in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A fully automatic anti-surge sleeve threading device for processing shielded cables, used to thread wires into the anti-surge sleeve, includes a base, a drive motor, a drive bracket, a transmission shaft, a drive wheel, a driven wheel, rolling bearings, an air compressor, an air pipe, a wire feeding pipe, a wire feeding bracket, a tapered tube, a guide end, and an anti-surge sleeve hanger. The drive motor, drive bracket, air compressor, and wire feeding bracket are respectively mounted on the base. The drive wheel and driven wheel, arranged close to each other and vertically, are respectively fitted onto the middle section of the transmission shaft through their central through holes. Both ends of the transmission shaft are respectively mounted on the drive bracket through the rolling bearings. One end of the transmission shaft connected to the drive wheel is connected to the shaft of the drive motor. The transverse wire feeding pipe is mounted on... Mounted on the wire feeding bracket, the outlet of the air compressor is connected to the wire feeding pipe through the air pipe. The large-diameter end of the tapered tube is connected to one end of the wire feeding pipe, and the small-diameter end of the tapered tube extends outward to form a straight pipe. Multiple transverse support columns are installed on the anti-surge sleeve bracket. One end of the wire passes through the gap between the driving wheel and the driven wheel, and then passes through the wire feeding pipe, the tapered tube, and the straight pipe in sequence before connecting to the guide end. A gap for high-pressure gas to pass through is provided between the inner wall of the straight pipe and the outer wall of the wire. The support column is close to the guide end. The outer diameter of the guide end is larger than the diameter of the wire but not larger than the outer diameter of the straight pipe. The surface of the guide end closest to the support column is a conical surface or a hemispherical surface.

[0008] Preferably, in order to facilitate the smooth insertion and forward movement of the guide end into the anti-surge sleeve through vibration, and for ease of processing and assembly, the guide end includes a housing, a guide end, a terminal block, and a miniature vibration motor. The miniature vibration motor is installed inside the housing, which is formed by two semi-circular shells joined together. The guide end, with a conical or hemispherical surface, is installed at one end of the housing and close to the support column. The terminal block, equipped with a welding cup, is installed at the other end of the housing and welded to the wire.

[0009] Preferably, in order to facilitate assembly, reduce volume, and increase smoothness, the two semi-circular shells are welded together, the outer shell and the guide end are welded together, and the outer shell and the terminal are welded together.

[0010] Preferably, in order to better guide the high-pressure gas to push the guide end forward, the wall of the feed tube is provided with an air inlet, and the air inlet is inclined at 30°-60° from the outer end to the inner end towards the tapered tube.

[0011] Preferably, in order to better guide the high-pressure gas to push the guide head forward, there are two air inlets arranged sequentially along the axial direction of the feed pipe, and the outlet of the air compressor is connected to the outer ends of the two air inlets through two air pipes respectively.

[0012] Preferably, in order to prevent the wire from deviating from the driving wheel and the driven wheel and to improve the reliability of pushing the wire, the middle part of the outer circumference of the driving wheel and the middle part of the outer circumference of the driven wheel are respectively provided with limiting concave rings for limiting the wire, and the wire is simultaneously located in the limiting concave rings of the corresponding driving wheel and the driving wheel.

[0013] Preferably, to facilitate the binding and fixing of one end of the anti-surge sleeve, an annular groove for binding and fixing the anti-surge sleeve is provided on the outer wall of the middle section of the straight pipe.

[0014] Preferably, in order to achieve a smoother and more reliable driving effect on the wire, one drive bracket, two drive shafts, one drive wheel, one driven wheel and four rolling bearings together constitute a drive assembly. The three drive assemblies are installed on the base in sequence. The shaft of the drive motor is connected to the drive shaft corresponding to one of the drive assemblies. A pulley is installed on the drive shaft connected to the drive wheel. Adjacent pulleys are connected by a belt. The wire passes through the three drive assemblies in sequence.

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

[0016] This invention designs a series of components that work together: a drive motor, a transmission shaft, a driving wheel, a driven wheel, rolling bearings, an air compressor, an air pipe, a wire feed pipe, a tapered tube, and a guide end. The drive motor rotates the driving wheel, which in turn moves the wire within the wire feed pipe and the tapered tube. The guide end moves forward within the anti-surge sleeve to expand the sleeve, thus smoothly enveloping the wire. Simultaneously, high-pressure gas continuously propels the guide end forward, improving threading efficiency. Ultimately, this invention achieves fully automated wire threading, significantly improving threading efficiency. Furthermore, the addition of a micro-vibration motor to the guide end allows for smoother expansion of the anti-surge sleeve during its movement, preventing difficulties in expansion that could hinder the guide end's continued movement.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-7 As shown, the fully automatic anti-surge sleeve threading device for shielded cable processing of the present invention is used to thread the wire 1 into the anti-surge sleeve 21. It includes a base 16, a drive motor (not visible in the figure due to being blocked by the drive bracket 2), a drive bracket 2, a transmission shaft 3, a drive wheel 7, a driven wheel 4, a rolling bearing 6, an air compressor 9, an air pipe 10, a wire feeding pipe 11, a wire feeding bracket 15, a tapered pipe 12, a guide end 14, and an anti-surge sleeve hanger 17. The drive motor, drive bracket 2, air compressor 9, and wire feeding bracket 15 are respectively mounted on the base 16. The anti-surge sleeve hanger 17 can be mounted on the base 16 or independently mounted on the ground. The drive wheel 7 and driven wheel 4, close to each other and arranged vertically, are respectively fitted onto the middle section of the transmission shaft 3 through their central through holes. The two ends of the transmission shaft 3 are respectively mounted on the drive bracket 2 through rolling bearings 6. The transmission shaft 7 is connected to the drive wheel 7... One end of the moving shaft 3 is connected to the rotating shaft of the drive motor. The transverse feed pipe 11 is installed on the feed support 15. The outlet of the air compressor 9 is connected to the feed pipe 11 through the air pipe 10. The large diameter end of the tapered pipe 12 is connected to one end of the feed pipe 11. The small diameter end of the tapered pipe 12 extends outward to form a straight pipe 13 that is interconnected. Multiple transverse support columns 18 are installed on the anti-surge sleeve bracket 17. One end of the wire 1 passes through the gap between the driving wheel 7 and the driven wheel 4 and then passes through the feed pipe 11, tapered pipe 12, and straight pipe 13 in sequence before connecting to the guide end 14. A gap is provided between the inner wall of the straight pipe 13 and the outer wall of the wire 1 for high-pressure gas to pass through. The support column 18 is close to the guide end 14. The outer diameter of the guide end 14 is larger than the diameter of the wire 1 but not larger than the outer diameter of the straight pipe 13. The surface of the guide end 14 near the support column 18 is a conical surface or a hemispherical surface.

[0026] like Figures 1-7 As shown, the present invention also discloses the following more optimized specific structures:

[0027] To facilitate the smooth insertion and forward movement of the guide end 14 into the anti-surge sleeve 21 via vibration, and for ease of processing and assembly, the guide end 14 includes a housing, a guide end 145, a terminal 142, and a miniature vibration motor 144. The miniature vibration motor 144 is installed inside the housing, which is formed by two semi-circular shells 143 joined together. The guide end 145, with a conical or hemispherical surface, is installed at one end of the housing near the support column 18. The terminal 142, equipped with a solder cup 141, is installed at the other end of the housing and is soldered to the wire 1 through the solder cup 141. The switch for the miniature vibration motor 144 extends from the terminal 142 to control the start and stop of the miniature vibration motor 144, while avoiding the extended switch from affecting the smooth movement of the guide end 14.

[0028] To facilitate assembly, reduce volume, and increase smoothness, the two semi-circular shells 143 are welded together, the outer shell and the guide end 145 are welded together, and the outer shell and the wiring end 142 are welded together.

[0029] In order to better guide the high-pressure gas to push the guide end 14 forward, the pipe wall of the feed pipe 11 is provided with an air inlet 20. The air inlet 20 is inclined at 30°-60° from the outer end to the inner end towards the cone pipe 12, preferably 45°.

[0030] In order to better guide the high-pressure gas to push the guide end 14 forward, there are two air inlets 20, which are arranged sequentially in the axial direction of the feed pipe 11. The outlet of the air compressor 9 is connected to the outer ends of the two air inlets 20 through two air pipes 10.

[0031] To prevent the wire from deviating from the driving wheel 7 and the driven wheel 4 and to improve the reliability of pushing the wire 1, the middle part of the outer circumference of the driving wheel 7 and the middle part of the outer circumference of the driven wheel 4 are respectively provided with limiting concave rings 5 ​​for limiting the wire 1. The wire 1 is simultaneously located in the limiting concave rings 5 ​​of the corresponding driving wheel 7 and the limiting concave rings 5 ​​of the driven wheel 4.

[0032] To facilitate the binding and fixing of one end of the anti-surge sleeve 21, an annular groove 19 for binding and fixing the anti-surge sleeve 21 is provided on the outer wall of the middle section of the straight pipe 13.

[0033] To achieve a smoother and more reliable driving effect on the wire 1, a drive bracket 2, two drive shafts 3, a drive wheel 7, a driven wheel 4, and four rolling bearings 6 together constitute a drive assembly. The three drive assemblies are installed sequentially on the base 16. The shaft of the drive motor is connected to the drive shaft 3 corresponding to one of the drive assemblies. A pulley (not marked in the figure) is installed on the drive shaft 3 connected to the drive wheel 7. Adjacent pulleys are connected by a belt 8. The wire 1 passes through the three drive assemblies in sequence.

[0034] Combination Figures 1-7 In application, first place the anti-surge sleeve 21 on multiple support columns 18, manually insert the guide end 14 into one end of the anti-surge sleeve 21, and pull that end of the anti-surge sleeve 21 to fit over the straight pipe 13. Use the strap 22 to tie the part of the anti-surge sleeve 21 near that end into the annular groove 19, thus fixing one end of the anti-surge sleeve 21 to the straight pipe 13. Then turn on the drive motor, air compressor 9 and micro vibration motor 144. The drive wheel 7 starts to rotate, using friction to push the wire 1 towards the guide end 14. The driven wheel 4 rotates accordingly, working with the drive wheel 7 to ensure sufficient friction on the wire 1. At the same time, the air compressor 9 generates high-pressure gas, which passes through the air pipe 10, the wire delivery pipe 11 and the tapered pipe 1 in sequence. 2. The straight pipe 13 and part of the anti-surge sleeve 21 exert a forward thrust on the guide end 14. When the high-pressure gas passes through the tapered pipe 12, it will be pressurized due to the reduced cross-section, which will help push the guide end 14. The guide end 14 expands and moves forward inside the anti-surge sleeve 21, allowing the wire 1 to move forward continuously inside the anti-surge sleeve 21. The guide end 14 and the wire 1 move forward continuously and are supported by the support column 18 to prevent the wire 1 from bending and affecting the smooth threading process. Until the wire 1 is completely threaded into the anti-surge sleeve 21, the drive motor, air compressor 9 and micro vibration motor 144 are turned off. The anti-surge sleeve 21 is removed from the straight pipe 13, and the guide end 14 is separated from the wire 1. The anti-surge sleeve 21 shrinks and covers the wire 1 under its own elasticity, resulting in a shielded cable.

[0035] Generally, when using this invention for threading, the length of the wire 1 to be threaded is between 1 and 3 meters, which is not very long. Therefore, although the high-pressure gas will leak inside the anti-surge sleeve 21, there is still a certain amount of airflow to push the guide end 14. Combined with the pushing force of the drive wheel 7 on the wire 1 and the vibration of the micro vibration motor 144, the guide end 14 can smoothly expand the anti-surge sleeve 21 and move forward. This invention is not suitable for threading operations with excessively long lengths (such as more than 5 meters), because when the length is too long, the high-pressure gas is difficult to reach the guide end 14, and the thrust loss of the drive wheel 7 will also be greater, which will affect the normal threading function.

[0036] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
