Description

Technical Field

[0001] This application relates to the field of cables, and more particularly to the field of cable manufacturing. Background Technology

[0002] In medical cables, ultra-fine cables are commonly used. These cables typically have a diameter of around φ0.5mm, and can even be as thin as φ0.1mm, φ0.03mm, or smaller, and are often insulated wires or coaxial cables. Due to their thinness, light weight, and flexibility, these cables are widely used in precision fields such as microelectronic packaging (e.g., chip bonding wires, interconnects), precision medical equipment (e.g., endoscope leads, implantable sensor connectors), miniature sensors, high-end headphones, and miniature coils.

[0003] Currently, the mainstream method for winding such ultra-fine cables still heavily relies on manual operation. Operators, relying on experience, use their hands or simple auxiliary tools to wind the cable from the pay-off reel to the take-up reel (such as a bobbin, spool, or coil bobbin). However, this manual operation mode has significant inherent drawbacks, such as low production efficiency and lack or instability in tension control. These shortcomings of manual winding, especially the problem of uncontrolled tension, pose a serious challenge to the performance of ultra-fine cables and the quality of the final product.

[0004] In view of this, the present invention is proposed.

[0005] Application content

[0006] This invention provides a winding system and method for ultra-fine cables. This invention enables automatic winding of ultra-fine cables and allows for precise control of the tension applied to the cable.

[0007] On one hand, the present invention provides a winding system for ultra-fine cables, including an unwinding module, a tension adjustment module, and a winding module;

[0008] The winding module includes a winding shaft and a winding motor;

[0009] The unwinding module is located upstream of the winding module; the ultra-fine cable passes through the unwinding unit and is wound onto the reel of the winding module;

[0010] The tension adjustment module, located between the unwinding module and the winding module, is used to adjust the tension on the cable. The tension adjustment module includes a U-shaped frame and multiple shielding units. The inner side of the U-shaped frame has multiple evenly distributed air holes. The air holes spray high-speed gas towards the inner side of the U-shaped frame to suspend the ultra-fine cable. The shielding units correspond one-to-one with the air holes and are used to adjust the opening and closing degree of the air holes.

[0011] Furthermore, the blocking unit includes at least two blocking plates and a blocking motor; the blocking motor is connected to the control unit and is used to control the opening and closing degree of the blocking plates.

[0012] Furthermore, it also includes a control module, which is used to control the winding motor and the blocking motor, thereby indirectly adjusting the tension on the cable.

[0013] Furthermore, it also includes a temperature and humidity control module for adjusting the temperature and humidity of the environment in which the winding module is located.

[0014] Furthermore, it also includes a tension sensor for real-time monitoring of the tension on the cable and transmitting the detected value to the control module; the control module compares the detected value with the preset value and adjusts the winding speed of the winding motor and the opening and closing degree of the air hole in the winding module based on the comparison result.

[0015] Furthermore, it also includes a display unit for inputting and displaying control parameters.

[0016] Furthermore, it also includes a cutting unit for cutting extremely fine cables.

[0017] On the other hand, the present invention also provides a winding method based on the above-described winding system, comprising the following steps:

[0018] Step 1: Fix one end of the ultra-fine cable to the starting position of the reel;

[0019] Step 2: Input the preset values, humidity, and temperature into the display unit, and start the winding motor;

[0020] Step 3: The control module monitors and adjusts the tension value of the ultra-fine cable in real time.

[0021] Step 4: When the winding is finished, the cutting unit cuts the ultra-fine cable.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1) This invention enables the automatic winding of extremely fine cables.

[0024] 2) This invention achieves the adjustment of the tension on the cable by combining the adjustment of winding speed and support force, which is stable, reliable and has high adjustment accuracy.

[0025] 3) This invention avoids the influence of friction caused by traditional transmission methods (i.e., direct contact) by using a non-contact method, making tension adjustment more precise. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Figure 1 A side view of the winding system of this embodiment is shown. Figure 1 As shown, the winding system includes an unwinding module 20, a tension adjustment module 30, and a winding module 40. From left to right, these are the unwinding module 20, the tension adjustment module 30, and the winding module 40. The ultra-fine cable 10 is output from the unwinding module 20 and wound by the winding module 40, with the tension adjusted by the tension adjustment module 30 along the way. The tension adjustment module 30 includes a U-shaped frame 301 and a support 301, with the U-shaped frame 301 fixedly supported by the support 301.

[0034] Figure 2 A partial structural schematic diagram of the U-shaped frame in this embodiment is shown. Multiple air holes 303 are evenly distributed on the inner wall of the U-shaped frame 302 facing the cable 10. The air holes 303 uniformly eject airflow, so that the cable 10 is suspended and supported to achieve non-contact support.

[0035] Preferably, this embodiment also includes a blocking unit 304. Figure 3 A schematic diagram of the shading unit is shown. (For example...) Figure 3As shown, the shielding unit in this embodiment includes at least two shielding plates 3042 and a shielding motor 3041. The shielding plates 3042 move left and right under the drive of the shielding motor 3041, thereby controlling the opening and closing degree of the air hole 303, thereby realizing the tension adjustment of the cable 10.

[0036] Figure 4 This shows a top view of the structure of the winding module 40. For example... Figure 4 As shown, the winding module 40 includes a winding motor 401 and a winding shaft 402. The winding motor 401 determines the rotation speed of the winding shaft 402, and the winding speed also affects the tension on the cable 10.

[0037] Preferably, the surface of the reel 402 has a spiral groove to guide the winding of the cable 10.

[0038] Preferably, this embodiment also includes a control module 50. Figure 5 The diagram shows the control module 50. The control module 50 directly controls the winding motor 401 and the blocking motor 3041, thereby adjusting the tension on the cable 10.

[0039] Preferably, this embodiment also includes a tension sensor (not shown in the figure) for real-time monitoring of the tension on the cable 10 to generate a detection value. The control module 50 acquires this detection value and compares it with a preset value to obtain a comparison result. The control module 50 then jointly adjusts the winding motor 401 and the blocking motor 3041 based on the comparison result. Preferably, this embodiment can use the comparison result as an index to obtain the adjustment parameters of the winding motor 401 and the blocking motor 3041 by looking up a table. Furthermore, this table can be calibrated in advance through experiments.

[0040] Preferably, this embodiment also includes a temperature and humidity control module 60 for adjusting the temperature and humidity of the environment in which the winding system is located. The temperature and humidity control module 60 is directly controlled by the control module 50.

[0041] Preferably, it also includes a display unit for inputting and displaying control parameters.

[0042] Ideally, it also includes a cutting unit for cutting extremely fine cables.

[0043] On the other hand, the winding method based on the above winding system includes the following steps:

[0044] Step 1: Fix one end of the ultra-fine cable to the starting position of the reel;

[0045] Step 2: Input the preset values, humidity, and temperature into the display unit, and start the winding motor;

[0046] Step 3: The control module monitors and adjusts the tension value of the ultra-fine cable in real time.

[0047] Step 4: When the winding is finished, the cutting unit cuts the ultra-fine cable.
