[0041] The specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings.

[0042] The present application provides a film material winding mechanism 10, please refer to Figure 1 , Figure 2 and Figure 3 The film material winding mechanism 10 includes a winding roller 110 , a detection component 120 and a control component 130 .

[0043] The detection assembly 120 includes a movable roller 121, a fixed roller 122, a detection arm 123 and a position detection device 124, wherein the fixed roller 122 is disposed at a first end of the detection arm 123, and the movable roller 121 is disposed at a second end of the detection arm 123; the movable roller 121 can rotate relative to the fixed roller 122 along a first direction with the fixed roller 122 as the center under the action of gravity or other elastic components, so as to Figure 1 Taking the illustrated scenario as an example, the first direction is a clockwise rotation direction with the fixed roller 122 as the center.

[0044] During the rolling process of the first target film material 901, the first target film material 901 is rolled onto the rolling roller 110 after passing through the movable roller 121; when the rolling roller 110 rotates, it drives the first target film material 901 to apply a force to the movable roller 121 to rotate relative to the fixed roller 122 along the second direction with the fixed roller 122 as the center.

[0045] The position detection device 124 is used to detect the relative rotation position of the movable roller 121 with respect to the fixed roller 122 .

[0046] The control component 130 includes the first control component 131, which is connected to the position detection device 124, and the first control component 131 is used to control the winding rotation speed of the winding roller 110 according to the relative rotation position of the movable roller 121 relative to the fixed roller 122.

[0047] For example, when using the film material winding mechanism 10 provided in this embodiment to roll up the first target film material 901, please refer to Figure 1 The first target film material 901 passes under the movable roller 121, and the movable roller 121 rotates relative to the fixed roller 122 along a first direction with the fixed roller 122 as the center under the action of its own gravity or other elastic components; and then is rolled up to the winding roller 110.

[0048] For example, in this embodiment, the first end of the detection arm 123 may have a component for controlling the range of motion of the detection arm 123 and an elastic component for applying a force in a second direction to the detection arm 123 so that it exerts a downward pulling force on the first target film material 901 .

[0049] For example, when using the film material winding mechanism 10 provided in this embodiment to roll up the first target film material 901, please refer to Figure 1 , Figure 2 and Figure 3The detection component 120 detects the real-time position of the movable roller 121 relative to the fixed roller 122, and transmits the position signal to the first control component 131. The first control component 131 controls the winding speed of the winding roller 110 according to the signal to reduce the occurrence of the winding speed being too fast or too slow.

[0050] In some possible implementations, the winding roller 110 reciprocates along its radial direction.

[0051] The control component 130 also includes a second control component 132, which is connected to the position detection device 124 and is used to control the speed of the reciprocating movement of the winding roller 110 in the radial direction according to the relative rotation position of the movable roller 121 relative to the fixed roller 122.

[0052] In this embodiment, please refer to Figure 2 and Figure 3 When the winding roller 110 is winding the first target film material 901, the radial distance of the winding roller 110 is relatively large. In order to improve the use efficiency of the film winding mechanism 10, the first target film material 901 is radially spread over the winding roller 110 when being wound, and the winding roller 110 is radially reciprocating. The second control component 132 is connected to the detection component 120, and the real-time signal transmitted by the detection component 120 is used to control the radial reciprocating speed of the winding roller 110. For example, when it is detected that the movable roller 121 is at a lower position in the vertical direction, the first detection component 120 controls the winding speed of the winding roller 110 to increase, and the second detection component 120 controls the radial reciprocating speed of the winding roller 110 to increase.

[0053] In a possible implementation, the rotation plane of the detection arm 123 is perpendicular to the radial direction of the winding roller 110 .

[0054] In this embodiment, please refer to Figure 1 In order for the first target film material 901 to pass smoothly under the movable roller 121 and then be rolled up to the winding roller 110, the movable plane of the movable roller 121 should be radially perpendicular to the winding roller 110, and the rotating plane of the detection arm 123 should also be radially perpendicular to the winding roller 110.

[0055] In some possible implementations, the film winding mechanism 10 further includes a first roller 111 . In the vertical direction, the first roller 111 is higher than the winding roller 110 .

[0056] The film winding mechanism 10 further includes a second roller 112 . In the vertical direction, the second roller 112 is higher than the highest position of the motion trajectory of the movable roller 121 . In the horizontal direction, the movable roller 121 and the first roller 111 are located on both sides of the second roller 112 .

[0057] During the rolling process of the first target film material 901 , the first target film material 901 passes under the movable roller 121 , over the second roller 112 , and over the first roller 111 in sequence, and then is rolled up to the rolling roller 110 .

[0058] In this embodiment, please refer to Figure 4 In order to make the first target film material 901 pass through the bottom of the movable roller 121, the top of the second roller 112, and the top of the first roller 111 in sequence during the winding process and then be wound onto the winding roller 110, the first target film material 901 will not fall off the above rollers, and will always be subjected to a force rotating relative to the fixed roller 122 along the second direction with the fixed roller 122 as the center within the movable range of the movable roller 121, and will always be subjected to the upward pulling force of the first roller 111 and the second roller 112, and will finally be smoothly wound up, in the vertical direction, the first roller 111 should be higher than the winding roller 110, and the second roller 112 should be higher than the highest position of the movement trajectory of the movable roller 121, and in the horizontal direction, the movable roller 121 and the first roller 111 are located on both sides of the second roller 112.

[0059] In some possible implementations, the film winding mechanism 10 also includes a positioning and torsion assembly 140, and the positioning and torsion assembly 140 includes a first fixed roller 141 and a second fixed roller 142, the axis of the fixed roller is perpendicular to the extension line of the axis of the first roller 111, and is perpendicular to the transmission direction of the first target film material 901; the axis of the fixed roller intersects with the transmission direction of the first target film material 901; the first roller 111 and the second roller 112 are located on both sides of the fixed roller 122.

[0060] During the operation of the film winding mechanism 10, before passing through the first fixed roller 141, the first surface of the first target film material 901 faces the third direction; when passing through the first fixed roller 141, the first surface of the first target film material 901 faces the side of the first target film material 901 close to the first fixed roller 141; when passing through the second fixed roller 142, the first surface of the first target film material 901 faces the side of the first target film material 901 away from the second fixed roller 142; after passing through the second fixed roller 142, the first surface of the first target film material 901 faces the fourth direction.

[0061] In this embodiment, the third direction is a downward direction perpendicular to the transmission direction of the first target film material 901, and the fourth direction is an upward direction perpendicular to the transmission direction of the first target film material 901. Figure 5 and Figure 6 , when the first target film material 901 is transferred to the second roller 112, its first surface faces the third direction, and when it is finally rolled up, the first surface needs to face the fourth direction, so the first target film material 901 needs to be turned over before reaching the winding roller 110. The positioning and twisting assembly 140 is provided here, which can simultaneously meet the situation that the first target film material 901 needs to be turned over and does not need to be turned over. For example, during the operation of the film winding mechanism 10, when the direction needs to be turned over, before passing through the first fixed roller 141, the first surface of the first target film material 901 faces the third direction; when passing through the first fixed roller 141, the first surface of the first target film material 901 faces the side of the first target film material 901 close to the first fixed roller 141; when passing through the second fixed roller 142, the first surface of the first target film material 901 faces the side of the first target film material 901 away from the second fixed roller 142; after passing through the second fixed roller 142, the first surface of the first target film material 901 faces the fourth direction, realizing the turning over of the first target film material 901. When the orientation does not need to be reversed, it is only necessary that the first target film material 901 is always located at one side of the positioning and twisting assembly 140 when passing through the positioning and twisting assembly 140 .

[0062] In some possible implementations, the position detection device 124 includes a sensor, and the sensor is used to detect the position of the movable roller 121 .

[0063] Please refer again Figure 2 The position detection component 120 uses the sensor, which transmits the position signal to the first control component 131 and the second control component 132 by detecting the position of the movable roller 121. The first control component 131 and the second control component 132 control the winding speed and radial moving speed of the winding roller 110 according to the signal, so that the winding speed of the winding roller 110 will not be too large or too small, reducing the risk of the first target film material 901 falling off or deforming, while improving the use efficiency of the film material winding mechanism 10.

[0064] Furthermore, the sensor includes an angle sensor.

[0065] In some possible implementations, the detection assembly 120 further includes an adjustment assembly for adjusting the rotation range of the detection arm 122 .

[0066] In this embodiment, please refer to Figure 2 The adjustment component includes a cylinder 125 and a gear 126, which are used to adjust the rotation range of the detection arm 122. For example, the rotation range of the detection arm is set to 0-60°. When the sensor detects that the detection arm rotates beyond the set angle, a signal is fed back to the adjustment component. After the adjustment component receives the signal, the cylinder 125 drives the gear 126 to drive the detection arm to rotate back to the set angle range.

[0067] The present application also provides a film material laminating mechanism 20, please refer to Figure 7 and Figure 8 The film material laminating mechanism 20 is used to laminate and roll up the first target film material 901 and the second target film material 902 . The film material laminating mechanism 20 includes the above-mentioned film material rolling mechanism 10 .

[0068] During the operation of the film material bonding mechanism 20, before passing through the first roller 111, the transmission direction of the first target film material 901 is the fifth direction of the second roller 112 toward the first roller 111, and the transmission direction of the second target film material 902 is the sixth direction different from the fifth direction; after passing through the first roller 111, the second target film material 902 is bonded to the side of the first target film material 901 close to the winding roller 110; the winding roller 110 is used to wind up the first target film material 901 and the second target film material 902 after bonding.

[0069] The present application also provides a release film re-dispensing device 30, please refer to Fig. 9 The release film re-dispensing device 30 includes the aforementioned film material bonding mechanism 20, and is used to tear off the first target film material 901 from the third target film material 903, and bond a second target film material 902 different from the first target film material 901 to the third target film material 903, wherein the first target film material 901 includes a release film of a first width, and the second target film material 902 includes a release film of a second width.
