[0003] Currently, before winding the electronic-grade fiberglass cloth, the air shaft and paper tube are statically inflated under normal conditions, and then placed on the frame for rotation to wind the fiberglass cloth onto the straight cylinder.

[0004] However, under the influence of gravity, the coaxiality of the paper tube and the air shaft will deviate. During winding, the misalignment between the air shaft and the paper tube will cause indentations or even wrinkles on the electronic-grade fiberglass cloth, affecting the quality of the product. Summary of the Invention

The winding device includes: a support assembly 1 having a support space 10 for supporting the air expansion shaft 200, the size of which is adjustable; and a pneumatic slip ring 2 disposed on the inner wall of the support space 10, the pneumatic slip ring 2 including a relatively rotatable stationary slip ring 21 and a movable slip ring 22, the stationary slip ring 21 containing a... There is an air supply chamber, and the moving slip ring 22 is provided with a gas flow channel that is connected to the air supply chamber and the air expansion shaft 200 respectively; the stationary slip ring 21 is connected to the air supply pipeline 300, and the moving slip ring 22 is connected to the air expansion shaft 200 so that air is supplied to the air expansion shaft 200 through the stationary slip ring 21 and the moving slip ring 22 while the air expansion shaft 200 rotates; the detection component 3 is set on the side of the air expansion shaft 200 and opposite to the air expansion shaft 200, and the runout value of the air expansion shaft 200 is detected by the detection component 3.

[0027] According to the present invention, a winding device is used to wind material onto a support cylinder 100, the support cylinder 100 being sleeved on an air expansion shaft 200. The winding device includes a support assembly 1, a pneumatic slip ring 2, and a detection assembly 3. The support assembly 1 has a support space 10 for supporting the air expansion shaft 200, the size of which is adjustable. The pneumatic slip ring 2 is disposed on the inner wall surface of the support space 10, and includes a relatively rotatable stationary slip ring 21 and a movable slip ring 22. The slip ring 21 has an air supply chamber, and the moving slip ring 22 has a gas flow channel that connects to both the air supply chamber and the air expansion shaft 200. The stationary slip ring 21 is connected to the air supply pipeline 300, and the moving slip ring 22 is connected to the air expansion shaft 200, so that air is supplied to the air expansion shaft 200 through the stationary slip ring 21 and the moving slip ring 22 while the air expansion shaft 200 rotates. The detection component 3 is located to the side of the air expansion shaft 200 and faces it, and detects the runout value of the air expansion shaft 200. This configuration allows for air supply while the air expansion shaft 200 rotates, and the detection component 3 automatically detects the runout value of the air expansion shaft 200 and calibrates the air expansion shaft 200 based on the detected runout value. The structure is simple and highly automated, avoiding the problem of indentations on the fiberglass cloth after winding, thus improving product quality.

[0028] Taking the winding of fiberglass cloth as an example, this application first places the support cylinder 100 on the air expansion shaft 200, and then winds the fiberglass cloth onto the support cylinder 100 during the rotation of the air expansion shaft 200.

[0029] Specifically, the winding device further includes a control valve 301, which is installed on the air supply line 300 to control the pressure within the air supply line 300. Preferably, the control valve 301 is an E / P pressure regulating valve to output a controllable air pressure.

[0030] In this application, as Figure 1 and Figure 2 As shown, the support assembly 1 further includes: a first support base 11 and a second support base 12, which are arranged opposite to each other and spaced apart to form a support space 10 between them. A pneumatic slip ring 2 is disposed on the first support base 11 and / or the second support base 12. The first support base 11 and the second support base 12 are movably disposed relative to each other. Each of the first support base 11 and the second support base 12 is provided with a clamp to hold both ends of the air expansion shaft 200.

[0031] Furthermore, the winding device also includes: a base 4, a first support 11 and a second support 12 spaced apart along the extending direction of the base 4; and a first driving component 5, which includes a first driving rod 50 connected to the first support 11, driving the first support 11 to move along the extending direction of the base 4. This arrangement allows the first support 11 and the second support 12 to move and clamp air shafts 200 of different sizes. The first driving rod 50 is a hydraulic rod, an electric actuator, or a cylinder piston rod. A linear bearing is provided on the base 4, and both the first support 11 and the second support 12 are connected to the linear bearing.

[0032] Furthermore, the winding device also includes a second driving component 6, which includes a second driving rod 60 connected to the second support base 12. The second driving rod 60 drives the second support base 12 to move along the extending direction of the base 4. Preferably, the second driving rod 60 is a hydraulic rod, an electric actuator, or a cylinder piston rod. The position of the second support base 12 is adjusted by the second driving rod 60.

[0033] In this application, the winding device further includes a lifting assembly 7, disposed within the support space 10. The lifting assembly 7 includes a vertically movable lifting bracket 70. After the air expansion shaft 200 is lifted to a predetermined position by the lifting bracket 70, the air expansion shaft 200 is supported by a first support seat 11 and a second support seat 12. Preferably, the lifting bracket 70 includes a first body, a second body, and a third body connected in sequence, with the first body and the third body arranged opposite to each other. The lifting bracket 70 is U-shaped and supports the connecting shafts at both ends of the air expansion shaft 200.

[0034] Specifically, the lifting assembly 7 includes: a lifting cylinder 71 disposed within the support space 10, and a lifting bracket 70 disposed on the drive rod of the lifting cylinder 71; there are at least two lifting cylinders 71, spaced apart, and at least two lifting brackets 70, each corresponding to one of the lifting cylinders 71. This arrangement allows the lifting cylinders 71 to lift the air shaft 200 to a designated clamping position, and then controls the movement of the first support seat 11 and the second support seat 12 to clamp the air shaft 200. This eliminates the need for manual positioning of the air shaft 200, saving labor and improving the positioning accuracy of the air shaft, thus preventing the danger and safety accidents caused by the air shaft 200 falling during operation.

[0035] The winding device also includes a support frame 8, of which there are at least two. A lifting cylinder 71 is mounted on the support frame 8. The support frame 8 includes a first frame, a second frame, and a third frame connected in sequence. The first frame and the third frame are opposite to each other, and the second frame is opposite to the base 4. The lifting cylinder 71 is mounted on the second frame. The first drive component 5 and / or the second drive component 6 are located between the first frame and the third frame. This arrangement makes the overall structure more compact and saves the installation space occupied by each component.

[0036] In the embodiment provided by the present invention, the detection component 3 is a runout detector, and the horizontal distance between the detection component 3 and the axis of the air expansion shaft 200 is 45cm to 60cm. The runout detector is used to monitor and measure the runout of the air expansion shaft 200, which is used to test whether the coaxiality of the air expansion shaft 200 and the support cylinder 100 meets the requirements.

[0037] The winding device of this application also includes a control module, which is connected to the first drive component, the second drive component, the lifting cylinder 71 and the control valve 301 respectively.

[0038] The present invention also provides a winding method applicable to the winding device of the above embodiments. The winding method includes: before winding the material, filling the air expansion shaft with a first pressure gas; while controlling the air expansion shaft 200 to rotate, filling the air expansion shaft 200 with a second pressure gas; detecting the runout value of the air expansion shaft 200, comparing the detected actual runout value with a preset runout threshold, and if the actual runout value is within the runout threshold range, ending the inflation.

[0039] When the actual runout value exceeds the runout threshold, the winding method further includes: reducing the pressure inside the air expansion shaft 200 to a third pressure; while controlling the air expansion shaft 200 to rotate in the opposite direction, continuing to inject gas into the air expansion shaft 200 until the actual runout value is within the runout threshold range. Preferably, the third pressure is 0.05 MPa.

[0040] Then, control the air shaft 200 to rotate in the initial rotation direction and fill the air shaft 200 with a second pressure gas; detect the runout value of the air shaft 200, compare the detected actual runout value with the preset runout threshold, and if the actual runout value is within the runout threshold range, end the inflation.

[0041] Before winding the material, the first drive component, the second drive component, the lifting cylinder 71 and the control valve 301 are debugged.

[0042] Preferably, the first pressure is 0.05 MPa to ensure that the support cylinder 100 and the air expansion shaft 200 are slightly tightened and fixed. Then, the control module controls the servo motors on the first support seat 11 and / or the second support seat 12 to rotate, thereby driving the air expansion shaft 200 to rotate. The rotation speed of the air expansion shaft 200 is 1000 to 3000 rpm. At this time, the precision E / P pressure regulating valve continues to control the input of compressed gas into the air pipe, and the air pressure gradually increases from 0.05 MPa before the air expansion shaft 200 rotates to 0.25 MPa (second pressure). With the high-speed circular motion, the concentricity of the support cylinder 100 and the air expansion shaft 200 gradually becomes consistent. At the same time as the rotation, a precision non-contact vibration tester detects the real-time vibration of the support cylinder 100. If the detected vibration value meets the system setting requirements, then the inflation process ends.

[0043] The beneficial effects of this application are: automated and rapid inflation of the air shaft, with inflation pressure freely adjustable via the system's built-in touchscreen, and the current pressure value displayed on the touchscreen interface. This device ensures uniform inflation during air shaft rotation, utilizing the centrifugal force generated by high-speed rotation to guarantee the coaxiality of the support cylinder and air shaft, solving the problem of poor coaxiality between the support cylinder and air shaft during static inflation. Simultaneously with rotational inflation, a high-precision runout tester measures and displays the runout of the rotating support cylinder in real time. When the displayed runout value meets the set threshold, it indicates that the inflation is satisfactory; otherwise, the control system issues a reverse command to reverse the inflation process until the support cylinder runout meets the set runout threshold, completing the inflation process.

[0044] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0045] According to the present invention, a winding device is used to wind material onto a support cylinder 100, the support cylinder 100 being sleeved on an air expansion shaft 200. The winding device includes a support assembly 1, a pneumatic slip ring 2, and a detection assembly 3. The support assembly 1 has a support space 10 for supporting the air expansion shaft 200, the size of which is adjustable. The pneumatic slip ring 2 is disposed on the inner wall surface of the support space 10, and includes a relatively rotatable stationary slip ring 21 and a movable slip ring 22. The slip ring 21 has an air supply chamber, and the moving slip ring 22 has a gas flow channel that connects to both the air supply chamber and the air expansion shaft 200. The stationary slip ring 21 is connected to the air supply pipeline 300, and the moving slip ring 22 is connected to the air expansion shaft 200, so that air is supplied to the air expansion shaft 200 through the stationary slip ring 21 and the moving slip ring 22 while the air expansion shaft 200 rotates. The detection component 3 is located to the side of the air expansion shaft 200 and faces it, and detects the runout value of the air expansion shaft 200. This configuration allows for air supply while the air expansion shaft 200 rotates, and the detection component 3 automatically detects the runout value of the air expansion shaft 200 and calibrates the air expansion shaft 200 based on the detected runout value. The structure is simple and highly automated, avoiding the problem of indentations on the fiberglass cloth after winding, thus improving product quality.
