[0036] Embodiment one

[0037] As shown in Figures 1-3 , it is a schematic view of the three-dimensional structure of the winding device. Figure 1 Figure 2 ​Figure 1 is a schematic view of the cooperation between the winding member 3 and the sensing member 4; Figure 3 Figure 2 is a schematic view of the cooperation between the rotating shaft 11, the winding member 3 and the force receiving member 8. The winding device of the present application comprises a rotating assembly 1, a driving member 2, a winding member 3, a sensing member 4 and a transmission member 5. The output end of the driving member 2 is connected with the rotating assembly 1. The winding member 3 is arranged on the rotating assembly 1. The sensing member 4 is arranged on the outer surface of the winding member 3. The transmission member 5 is electrically connected with the winding member 3.

[0038] In use, the film material (brightness enhancement film) needs to be wound on the outer surface of the winding member 3. The driving member 2 is operated to drive the rotating assembly 1 to rotate. The rotating assembly 1 drives the winding member 3 to rotate. The winding member 3 gradually winds the film material on its surface in the process of rotation. The sensing member 4 is located between the film material and the winding member 3. The pressure between the film material and the winding member 3 is collected by the sensing member 4. The sensing member 4 transmits the collected detection signal to the transmission member 5. The transmission member 5 outputs the detection signal. Then, the output of the driving member 2 is adjusted according to the detection signal. In the present embodiment, the specific position of the transmission member 5 is not specifically limited. The transmission member 5 only needs to be within the range of receiving and transmitting signals, for example, it is arranged beside the rotating assembly 1 or directly arranged on the rotating assembly 1.

[0039] Specifically, after the transmission member 5 outputs the detection signal, the operator can adjust the driving member 2 according to the detection signal, for example, the output of the driving member 2 is adjusted to be larger, so that the rotating speed of the rotating assembly 1 becomes faster, and vice versa. In the present embodiment, the detection signal is a pressure signal. According to the detection signal, the size of the force of the film material acting on the winding member 3 can be known. When the pressure is too large, the defects (defective parts) on the winding member 3 will be transferred to the film material, causing the film material to be defective. Therefore, by adjusting the output of the driving member 2, the pressure between the film material and the winding member 3 can be within the required range, so as to ensure the quality of the wound film material.

[0040] Please refer to Figure 2 In the present embodiment, the winding member 3 is a hollow roller. The sensing member 4 is arranged on a partial area of the outer surface of the winding member 3. That is, the length of the sensing member 4 after being unfolded is less than the circumference of the winding member 3, so as to facilitate the installation of the sensing member 4 and reduce the cost.

[0041] Please refer to Figure 1The rotating assembly 1 comprises a rotating shaft 11, two supporting seats (not shown in the figure) and two chucks (not shown in the figure), the two supporting seats are rotatably connected with the two chucks respectively, the two ends of the rotating shaft 11 are detachably connected with the two chucks respectively, the winding element 3 is sleeved on the outer surface of the rotating shaft 11, and the output end of the driving element 2 is connected with any one of the chucks. In work, the driving element 2 drives the chuck to rotate, the chuck drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the winding element 3 to rotate, so that the winding of the film material is realized. Specifically, the driving element 2 is a motor; the output end of the driving element 2 is the output shaft of the driving element 2, and the connection between the output shaft of the driving element 2 and the chuck is realized by using the existing means, for example, the chuck extends outwardly with a shaft rod (not shown in the figure), and the shaft rod and the output shaft of the driving element 2 are connected through a shaft coupling.

[0042] Further, the winding device further comprises a control element 6 and a speed changing element 7, the control element 6 is electrically connected with the transmission element 5 and the speed changing element 7, and the speed changing element 7 is connected with the output shaft of the driving element 2 and the rotating assembly 1. In work, the transmission element 5 transmits the detection signal to the control element 6, the control element 6 is used for adjusting the speed changing element 7, the driving element 2 has constant output, and the output of the driving element 2 is adjusted through the speed changing element 7, so that the rotating speed transmitted to the rotating assembly 1 is changed. Specifically, Figure 1 F1 in the figure is the film material feeding direction, and F2 is the signal transmission direction.

[0043] In the embodiment, the sensing element 4 is a thin film pressure sensor, which can detect the pressure of the film material acting on the winding element 3; the transmission element 5 is a pressure transmitter, which can receive the detection signal transmitted by the sensing element 4 and transmit the corresponding signal analog quantity to the control element 6 through PLC, for example, outputting a voltage in the range of 0-10V; the control element 6 is an automatic tension controller, which transmits a working signal to the speed changing element 7 after receiving the signal transmitted by the transmission element 5; the speed changing element 7 is a magnetic powder clutch, which can adjust the output of the driving element 2 according to the working signal transmitted by the control element 6, for example, the speed changing element 7 outputs a rotating speed smaller than that of the driving element 2 to the rotating assembly 1. It should be noted that the signal transmission between the sensing element 4, the transmission element 5, the control element 6 and the speed changing element 7 is a conventional means, and the signal transmission will not be further described herein.

[0044] Further, the winding device further comprises a force receiving element 8, the force receiving element 8 is arranged on the outer surface of the winding element 3, and the force receiving element 8 is in abutment with the sensing element 4, that is, the sensing element 4 is located between the force receiving element 8 and the winding element 3. In work, the film material is wound on the outer surface of the force receiving element 8 (i.e. the side away from the winding element 3), the force receiving element 8 evenly applies the pressure of the wound film material to the sensing element 4, so that the pressure signal collected by the sensing element 4 is more accurate. In the embodiment, the force receiving element 8 is made of soft material, for example, foam, which can not only better transmit the pressure of the wound film material to the sensing element 4, but also avoid damaging the film material.

[0045] In summary, the driving component 2 drives the rotating assembly 1 to rotate, and the rotating assembly 1 drives the winding component 3 to rotate together. During the rotation of the winding component 3, the film material is wound up. During the winding process, the winding component 3 is subjected to pressure from the film material, which is collected by the sensing component 4. The sensing component 4 transmits the collected detection signal to the transmission component 5. The detection signal transmitted by the transmission component 5 adjusts the output of the driving component 2 to ensure that the pressure on the winding component 3 is kept within the preset value. This avoids film transfer problems caused by excessive pressure between the film material and the winding component 3, thereby reducing the defective loss and cost of the film material and improving the quality of the film material.

[0047] like Figure 4 As shown, Figure 4 This is another three-dimensional structural diagram of the winding device. The difference between this embodiment and Embodiment 1 is that the winding device also includes a transmission component 9, which is connected to the output end of the speed change component 7 and the chuck respectively; during operation, the drive component 2 outputs through the speed change component 7, and the speed change component 7 drives the chuck to rotate through the transmission component 9.

[0048] The transmission component 9 includes a drive wheel 91, a driven wheel 92, and a transmission belt 93. The drive wheel 91 is connected to the output end of the speed change component 7. The driven wheel 92 is mounted on the shaft of the chuck. The transmission belt 93 is wound around the drive wheel 91 and the driven wheel 92. The speed change component 7 drives the drive wheel 91 to rotate. The drive wheel 91 drives the driven wheel 92 to rotate through the transmission belt 93. The driven wheel 92 then drives the chuck to rotate.

[0049] In this embodiment, the transmission component 7 is a dual-shaft magnetic powder clutch, with one shaft connected to the drive component 2 as the input shaft and the other shaft connected to the drive wheel 91 as the output shaft.

[0050] The arrangement of the transmission component 9 allows for flexible positioning of the drive component 2. For example, placing the drive component 2 at the bottom of the support base not only makes full use of the available space but also reduces the overall size of the winding device.

The width of the area wrapped by the sensor 4 is half the width of the take-up member 3. It can be understood that the unfolded length of the sensor 4 is equal to or greater than the circumference of the take-up member 3.

[0057] Example 6

[0058] The difference between this embodiment and Embodiment Two is that: the sensing element 4 is wrapped around a portion of the winding member 3, with the axial direction of the winding member 3 as its width, and the width of the area wrapped by the sensing element 4 is 1 / 2 of the width of the winding member 3. It can be understood that the unfolded length of the sensing element 4 is equal to or greater than the circumference of the winding member 3.

[0059] Example 7

[0060] like Figure 7 As shown, Figure 7 This is the fourth schematic diagram showing the cooperation between the take-up member 3 and the sensor 4. The difference between this embodiment and Embodiment 1 is that the sensor 4 wraps around the outer surface of the take-up member 3, meaning the sensor 4 completely encloses the take-up member 3. It can be understood that the unfolded length of the sensor 4 is equal to or greater than the circumference of the take-up member 3.
