Description

Technical Field

[0001] The present application relates to the technical field of coaxial cable production, and in particular to a cable braiding device and a process thereof. Background Art

[0002] Coaxial cable is a high-precision electronic component that can be used in radar systems, electronic countermeasure systems, and electronic measurement systems. The voltage standing wave ratio of coaxial cable is one of the important indicators to measure the electrical performance of coaxial cable. The voltage standing wave ratio refers to the sum of reflected signals caused by impedance mismatch when transmitting RF signals. This indicator determines the fit of the coaxial cable in the entire electronic system, which means that the voltage standing wave ratio directly determines the quality level of the RF coaxial cable.

[0003] The shielding layer of the coaxial cable is often produced by a braiding process. The utility model patent with reference authorization announcement number CN203931664U discloses a cable braiding machine, which includes a workbench, a wire taking-up device and a braiding device, both of which are arranged on the workbench, and the braiding device includes at least one rotating disk, and the wire taking-up device includes a fixed frame arranged on the workbench, a wire taking-up disk arranged on the fixed frame and located above the rotating disk, and a threading shaft that allows the metal wires on all spindles on the rotating disk to pass through, and the threading shaft is arranged on the fixed frame and located between the wire taking-up disk and the rotating disk.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: In order to ensure the smooth and stable braiding of the coaxial cable, the take-up reel often rotates at a uniform speed to reel the cable, but in the actual winding process, the take-up device inevitably produces periodic vibrations due to factors such as dimensional accuracy. This periodic vibration will cause periodic changes in the cable braiding structure, thereby causing regular periodic changes in the characteristic impedance of the cable. When transmitting radio frequency signals, the reflections caused by impedance mismatch will be periodically superimposed at a fixed frequency, causing the voltage standing wave ratio to have a very high peak at certain frequencies, affecting the performance of the cable. Summary of the invention

[0005] In the first aspect, in order to mitigate the high peak of the voltage standing wave ratio of the cable, the purpose of this application is to provide a braiding device for a cable, which adopts the following technical solution:

[0006] A cable braiding device comprises a braiding machine body and a wire-taking device connected to the braiding machine body, the wire-taking device comprises a base frame connected to the braiding machine body, a winding mechanism for winding up the cable, and a speed regulating mechanism for adjusting the moving speed of the cable, the speed regulating mechanism is located on a side of the winding mechanism close to the braiding machine body, the speed regulating mechanism comprises a direction adjusting cam and a first driving member for driving the direction adjusting cam to rotate, the first driving member is located on the base frame, the direction adjusting cam is rotationally connected to the base frame, and the outer edge surface of the direction adjusting cam is pressed and fitted against the cable.

[0007] By adopting the above technical solution, the braided cable moves toward the winding mechanism under the action of the winding mechanism, and the outer edge surface of the adjustment cam keeps in contact with the cable to control the moving speed of the cable. When the adjustment cam rotates, the moving direction of the cable will change with the rotation of the adjustment cam. The change in the moving direction of the cable will change the moving speed of the cable, thereby driving the structure of the braided shielding layer of the cable to change, thereby destroying the change in the characteristic impedance of the cable during the braiding process, reducing the regular reflection of electromagnetic waves in the cable, and optimizing the voltage standing wave ratio of the coaxial cable.

[0008] Preferably, the speed regulation mechanism also includes an auxiliary wheel, and a sliding member is slidably provided on the base frame to drive the outer edge surface of the adjustment cam to maintain contact with the outer cylindrical surface of the auxiliary wheel. The auxiliary wheel is located on the sliding member, and a speed regulation space for the cable to move and change speed is formed between the outer edge surface of the adjustment cam and the outer cylindrical surface of the auxiliary wheel.

[0009] By adopting the above technical solution, when the cable passes through the variable speed regulating space, the auxiliary wheel presses the cable against the outer cylindrical surface of the regulating cam, thereby making the change control of the cable moving speed facing the outer edge of the regulating cam more stable.

[0010] Preferably, the sliding member includes a sliding block slidably arranged on the base frame along the vertical direction and a reset elastic member fixedly arranged on the sliding block at one end, the reset elastic member is located on the side of the sliding block away from the adjustment cam, the other end of the reset elastic member is fixedly connected to the base frame, and the auxiliary wheel is rotatably connected to the sliding block.

[0011] By adopting the above technical solution, the resetting elastic member provides a force to the sliding block toward the adjustment cam, so that the outer circumferential surface of the auxiliary contact wheel is kept in contact with the outer edge surface of the adjustment cam.

[0012] Preferably, the wire taking-up device also includes a stable conveying mechanism, which is located on the side of the speed regulating mechanism close to the winding mechanism. The stable conveying mechanism includes two clamping wheels rotatably arranged on the base frame and a second driving member that drives the clamping wheels to rotate, and a clamping space for the cable to pass through is formed between the two clamping wheels.

[0013] By adopting the above technical solution, when the winding mechanism is winding the cable, the cables on the winding drum gradually increase so that the winding radius of the cable gradually increases, thereby causing the winding speed of the winding mechanism to gradually increase. This will cause the winding speed of the earlier wound portion of the cable on the same winding drum to be lower than the winding speed of the later wound portion of the cable, and the clamping wheel of the stable conveying mechanism only clamps and delivers the cable instead of winding the cable, so that the moving speed of the cable remains stable. As a result, the moving speed change of the cable woven by the braiding device is only controlled by the speed regulating mechanism, so that the moving speed of the cable presents a stable change.

[0014] Preferably, the wire taking-up device comprises a winding roller rotatably arranged on the base frame and a third driving member driving the winding roller to rotate, and the winding roller is detachably provided with a wire taking-up disk, and friction transmission is performed between the wire taking-up disk and the winding roller.

[0015] By adopting the above technical solution, the third driving member drives the winding roller to rotate to drive the take-up drum to reel in the cable delivered by the stable conveying mechanism. When the take-up drum is full of cables, it can be disassembled and replaced with a new one.

[0016] Preferably, the winding roller is detachably provided with a first positioning seat and a second positioning seat, the first positioning seat and the second positioning seat are both frictionally transmitted with the winding roller, the first positioning seat is embedded in one end of the take-up drum, and the second positioning seat is embedded in the other end of the take-up drum.

[0017] By adopting the above technical solution, the first positioning seat and the second positioning seat are respectively embedded in the two ends of the take-up drum, and the winding roller drives the first positioning seat and the second positioning seat to rotate through friction to drive the take-up drum to rotate. The take-up drum does not directly contact the take-up roller, thereby reducing the wear of the take-up drum.

[0018] Preferably, a slip adjustment mechanism is provided on the winding roller, and the slip adjustment mechanism includes a driving gear detachably provided to rotate with the winding roller and a driving slider slidably provided on the first positioning seat, and the driving slider is embedded in or disengaged from the tooth groove of the driving gear.

[0019] By adopting the above technical solution, the driving slider is embedded in the tooth groove to limit the relative rotation between the driving slider and the driving gear, so that the first positioning seat can rotate the winding roller so that the first positioning seat can drive the take-up drum to rotate. As the number of cables wound on the take-up drum increases, the winding radius increases so that the winding speed of the take-up drum increases. When the winding speed of the take-up drum is greater than the feeding speed of the stable conveying mechanism, the tension applied by the cable on the take-up drum drives the first positioning seat and the take-up roller to rotate relative to each other. At this time, the driving slider slides along the tooth surface of the driving gear to disengage from the tooth groove so that the first positioning seat and the take-up roller can slip, thereby protecting the cable. The driving gear is detachable, and the driving gear with different full tooth heights can be replaced, so that the cable tension required for the driving slider to slide out of the tooth groove can be adjusted.

[0020] Preferably, a rotation limiting mechanism for limiting the reversal of the take-up drum is provided on the winding roller, and the rotation limiting mechanism includes a ratchet fixedly arranged on the second positioning seat and a pawl cooperating with the ratchet, the pawl is rotatably connected to the base frame, and the axis of the ratchet coincides with the axis of the winding roller.

[0021] By adopting the above technical solution, the ratchet is fixedly connected to the second positioning seat so that the ratchet can be disassembled and assembled to the winding roller following the second positioning seat. When the second positioning seat is installed on the winding roller, the ratchet and the pawl cooperate to enable the winding drum to rotate only in one direction, thereby preventing the winding drum from reversing when slippage occurs between the winding drum and the winding roller.

[0022] Secondly, in order to mitigate the high peak of the voltage standing wave ratio of the cable, the present application provides a cable braiding process, which adopts the following technical solution:

[0023] A cable braiding process comprises the following steps:

[0024] S1, braiding, braiding the shielding layer on the outer wall of the cable (c);

[0025] S2, conveying, conveying the cable (c) and adjusting the moving speed of the cable (c);

[0026] S3, rewinding.

[0027] By adopting the above technical solution, when weaving the cable shielding layer, the conveying speed will change with the adjustment of the adjustment cam, and the braiding structure of the cable shielding layer will change with the change of the conveying speed, thereby destroying the periodic change of the cable characteristic impedance, reducing the regular reflection of electromagnetic waves in the cable, and optimizing the voltage standing wave ratio of the coaxial cable.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The braided cable moves toward the winding mechanism under the action of the winding mechanism, and the outer edge of the adjustment cam keeps in contact with the cable to control the moving speed of the cable. When the adjustment cam rotates, the moving direction of the cable will change with the rotation of the adjustment cam. The change in the moving direction of the cable will change the moving speed of the cable, which will drive the structure of the braided shielding layer of the cable to change, thereby destroying the change of the characteristic impedance of the cable during the braiding process, reducing the regular reflection of electromagnetic waves in the cable, and optimizing the voltage standing wave ratio of the coaxial cable;

[0030] 2. When the reeling mechanism reels the cable, the cable on the reel gradually increases so that the reeling radius of the cable gradually increases, thereby causing the reeling speed of the reeling mechanism to gradually increase. This will cause the reeling speed of the cable that is reeled earlier on the same reel to be lower than the reeling speed of the cable that is reeled later. The clamping wheel of the stable conveying mechanism only clamps and delivers the cable but does not reel it, thereby keeping the moving speed of the cable stable. As a result, the moving speed of the cable woven by the braiding device is only controlled by the speed regulating mechanism to keep the moving speed of the cable constantly changing.

[0031] 3. When weaving the cable shielding layer, the conveying speed will change with the adjustment of the directional cam, and the braiding structure of the cable shielding layer will change with the change of the conveying speed, thereby destroying the periodic change of the cable characteristic impedance, reducing the regular reflection of electromagnetic waves in the cable, and optimizing the voltage standing wave ratio of the coaxial cable.

[0047] The implementation principle of a cable braiding device and its process in an embodiment of the present application is as follows: the prepared cable c moves toward the winding mechanism 2 under the action of the winding mechanism 2, the second driving member 42 drives the clamping wheel 41 to rotate to stably convey the cable c, the first driving member 32 drives the adjusting cam 31 to rotate so that the moving direction of the cable c close to the clamping wheel 41 on the braiding machine body a side changes, thereby changing the moving speed of the cable c, and the third driving member 22 drives the winding roller 21 to rotate to drive the take-up reel winding clamping wheel 41 away from the cable c on the braiding machine body a side.

[0048] In order to alleviate the high peak of the voltage standing wave ratio of the cable C, the present application also discloses a braiding process for the cable.

[0049] Reference Figure 1 and Figure 2 The cable braiding process includes the following steps:

[0050] S1. Braiding: The braiding machine body a braids the shielding layer of the wire core to form a cable c.

[0051] S2. Conveying: The second driving member 42 drives the clamping wheel 41 to rotate so that the cable c located in the clamping space is kept in constant speed conveying, and the first driving member 32 drives the adjusting cam 31 to rotate so that the moving direction of the cable c attached to the outer edge surface of the adjusting cam 31 is adjusted, thereby changing the tension applied to the cable c in the braiding machine body a to change the length of the cable c between the braiding machine body a and the clamping wheel 41, thereby changing the moving speed of the cable c in the braiding machine body a.

[0052] S3, winding: The third driving member 22 drives the winding roller 21 to rotate to drive the take-up drum to rotate through friction transmission. When the winding speed of the take-up drum is less than the conveying speed of the clamping wheel 41, the rotation speed of the take-up drum is kept the same as the rotation speed of the winding roller 21 to reel the cable C. When the winding speed of the take-up drum is greater than the conveying speed of the clamping wheel 41, the take-up drum slips between the winding roller 21 under the action of the tension of the cable C.

[0053] The implementation principle of a braiding process for a cable C in an embodiment of the present application is as follows: the prepared cable C moves toward the winding mechanism 2 under the action of the winding mechanism 2, the second driving member 42 drives the clamping wheel 41 to rotate to stably convey the cable C, the first driving member 32 drives the adjusting cam 31 to rotate so that the moving direction of the cable C on the side of the clamping wheel 41 close to the braiding machine body a changes, thereby changing the tension applied to the cable c in the braiding machine body a to change the length of the cable c between the braiding machine body a and the clamping wheel 41, thereby changing the moving speed of the cable c in the braiding machine body a, and the third driving member 22 drives the winding roller 21 to rotate to drive the winding clamping wheel 41 of the take-up reel to move away from the cable C on the side of the braiding machine body a.
