[0044] The specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings.

[0045] The present application provides a film material winding mechanism 10, please refer to Figure 1 and Figure 2 The film material winding mechanism 10 includes a first roller 110 , a slide rail 100 , a position detection component 200 , a winding roller 310 and a winding control component 320 .

[0046] The slide rail 100 is vertically arranged, and the first roller 110 is arranged on the slide rail 100 and can move downward along the slide rail 100 under the action of gravity.

[0047] During the rolling process of the first target film material 910 , the first target film material 910 passes under the first roller 110 and is rolled onto the rolling roller 310 ; when the rolling roller 310 rotates, it drives the first target film material 910 to apply an upward pulling force to the first roller 110 .

[0048] The position detection component 200 is connected to the winding control component 320, and the position detection component 200 is used to detect the position of the first roller 110 on the slide rail 100. The winding control component 320 is used to control the winding speed of the winding roller 310 according to the position of the first roller 110 on the slide rail 100.

[0049] For example, when using the film winding mechanism 10 provided in this embodiment to separate the first target film 910, please refer to Figure 1 , the first target film material 910 passes under the first roller 110 , and the first roller 110 moves vertically on the slide rail 100 under the action of its own gravity to separate the first target film material 910 .

[0050] For example, when using the film material winding mechanism 10 provided in this embodiment to roll up the first target film material 910, please refer to Figure 1 , Figure 2 and Figure 3 The position detection component 200 detects the real-time position of the first roller 110 on the slide rail 100, and transmits the position signal to the winding control component 320. The winding control component 320 controls the winding speed of the winding roller 310 according to the signal to reduce the occurrence of the winding speed being too fast or too slow.

[0051] In some possible implementations, the film winding mechanism 10 also includes a second roller 120 and a third roller 130; the positions of the second roller 120 and the third roller 130 are fixed; in the horizontal direction, the first roller 110 is located between the second roller 120 and the third roller 130; in the vertical direction, the second roller 120 and the third roller 130 are not lower than the lowest position of the first roller 110 on the slide rail 100.

[0052] During the rolling process of the first target film material 910 , the first target film material 910 passes over the second roller 120 , under the first roller 110 , and over the third roller 130 in sequence, and then is rolled up to the rolling roller 310 .

[0053] In this embodiment, please refer to Figure 4In order for the first roller 110 to separate the first target film material 910 by its own weight, in the horizontal direction, the first roller 110 should be located between the second roller 120 and the third roller 130; in the vertical direction, the second roller 120 and the third roller 130 should not be lower than the lowest position of the first roller 110 on the slide rail 100.

[0054] Furthermore, in the vertical direction, the second roller 120 and the third roller 130 are higher than the highest position of the first roller 110 on the slide rail 100 .

[0055] In this embodiment, please refer to Figure 5 In order to make the first target film material 910 pass over the second roller 120, under the first roller 110 and over the third roller 130 in sequence during the winding process, so that the first target film material 910 will not fall off the above rollers, it is always subjected to the downward pulling force of the first roller 110 within the movable range of the first roller 110, and is always subjected to the upward pulling force of the fixed rollers, the second roller 120 and the third roller 130, and is finally smoothly wound, in the vertical direction, the second roller 120 and the third roller 130 should be higher than the highest position of the first roller 110 on the slide rail 100.

[0056] In some possible implementations, a counterweight block 311 with replaceable weight is disposed on the first roller 110 .

[0057] In this embodiment, please refer to Figure 6 Since the downward pulling force of the first roller 110 required for separating and winding different film materials is different, a counterweight block 311 with a replaceable weight is set on the first roller 110. For example, for film materials with greater viscosity, a counterweight block 311 with a heavier weight is used; for film materials with less viscosity, a counterweight block 311 with a lighter weight is used or no counterweight block 311 is used.

[0058] In some possible implementations, the position detection assembly 200 includes a first sensor 210 and a second sensor 220 , and the sensors are disposed on the slide rail 100 .

[0059] The slide rail 100 includes a first end and a second end along a vertical direction. The first end is an end of the slide rail 100 close to the second roller 120 , and the second end is an end of the slide rail 100 away from the second roller 120 .

[0060] The first sensor 210 is located at one end of the slide rail close to the first end, and the second sensor 220 is located at one end of the slide rail close to the second end.

For example, when the position of the first roller 110 is close to the second sensor 220, the winding control component 320 controls the winding speed of the winding roller 310 to increase; when the position of the first roller 110 is close to the first sensor 210, the winding control component 320 controls the winding speed of the winding roller 310 to decrease. In this way, the winding speed of the winding roller 310 will not be too large or too small, reducing the risk of the first target film 910 falling off or deforming, and at the same time controlling the movement range of the first roller 110 to be controlled between the first sensor 210 and the second sensor 220.

[0062] In some possible implementations, the sensor includes a photoelectric sensor or the like.

[0063] For example, when using the film material winding mechanism 10 provided in this embodiment, please refer to Figure 7 The photoelectric sensor continuously emits a light beam toward the target through the transmitter, and then the light beam returns from the reflective plate set on the first roller 110. The receiver of the photoelectric sensor receives the signal and filters out the useful signal through its detection circuit, thereby controlling the winding speed of the winding roller 310.

[0067] In this embodiment, please refer to Figure 8In order to make the first target film material 910 pass through the bottom of the fourth roller 140, the top of the second roller 120, the bottom of the first roller 110, and the top of the third roller 130 in sequence during the winding process, so that the first target film material 910 will not fall off the above rollers, and the first target film material 910 can be smoothly transferred to the second roller 120, and the first target film material 910 can always be subjected to an upward pulling force at the second roller 120, and finally be smoothly wound up, the second roller 120 should be located between the third roller 130 and the fourth roller 140 in the horizontal direction, and the fourth roller 140 should not be higher than the second roller 120 in the vertical direction.
