[0026] Embodiment 1

[0027] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 A film pressing device that can closely fit and avoid wrinkles comprises: a workbench 1, two groups of servo motors 2 are fixed on the upper side of the workbench 1, a bidirectional screw rod 3 is fixed in the output direction of the servo motor 2, a bearing seat 4 is connected to one side of the bidirectional screw rod 3, two sliding rods 5 are threadedly connected to the outer surface of the bidirectional screw rod 3, a bottom plate 6 is fixed to the axial center of the workbench 1, and a pressing member 7 is fixed on the upper side of the bottom plate 6;

[0028] The pressing member 7 includes a fixed plate 71, and the fixed plate 71 is fixed on the upper side of the bottom plate 6. A circular tube 1 72 and a circular tube 2 73 are fixed on the fixed plate 71. A moving part 74 is arranged on the upper side of the circular tube 1 72 and the circular tube 2 73, and a spring 75 is fixed between the circular tube 1 72 and the moving part 74.

[0029] The pressing member 7 also includes a connecting tube 1 76, and the middle part of the movable member 74 is fitted and slidably connected with the connecting tube 1 76, and the lower sides of both ends of the movable member 74 are fixed with connecting tubes 2 77, and the lower sides of the connecting tubes 1 76 and 2 77 are fixed with supporting plates 78, and a rotating roller 79 is fixed and rotatably provided on the supporting plate 78 through a movable connecting device.

[0030] By rotating the nut provided on the connecting tube 1 76 to rotate the thread, the movable member 74 moves downward, and the downward movement of the movable member 74 compresses the spring 75, and the support plate 78 and the roller 79 thereon also move downward through the connecting tube 1 76 and the connecting tube 2 77. At this time, the downward movement of the roller 79 flattens the film. At the same time, due to its free rotation characteristic, it can be ensured that the film will not produce wrinkles due to friction during the flattening process.

[0031] Embodiment 2

[0032] Based on the above embodiment 1, reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , the movable connection device is a ball bearing or a sliding bearing.

[0033] The top of the connecting pipe 76 is provided with a thread, and a nut is threadedly connected to the outer surface of the thread.

[0034] By rotating the nut provided on the connecting pipe 76 to rotate the thread, the moving member 74 can be moved upward or downward.

[0035] The inner wall surface of the fixing plate 71 and the outer surfaces of both sides of the supporting plate 78 are in close contact with each other.

[0036] Round rods 8 are welded to both ends of the bottom plate 6 .

[0037] The round round stick 8 can prevent the film from being worn and scratched during the movement.

[0038] The pressing member 7 is located between the two slide bars 5 .

[0039] Working principle: Please refer to Figure 1-Figure 5 As shown, first, the device is in a non-working state, the pressing member 7 is located between the two slide bars 5, and is connected to the circular tube 1 72 and the circular tube 2 73 through the spring 75, so that the moving member 74 is at a certain height. The roller 79 is connected to the support plate 78 through a movable connection device (such as a ball bearing or a sliding bearing) and can rotate freely.

[0040] When placing the film, the staff places the film to be pressed on the workbench 1 to ensure that the film covers the top of the pressing member 7. Then start the device, and by starting the servo motor 2, the motor drives the bidirectional screw 3 to rotate. Since the bidirectional screw 3 is threadedly connected with the two slide bars 5, when the bidirectional screw 3 rotates, the two slide bars 5 will move toward or away from each other. When the slide bars 5 move to the predetermined position, the film is flattened and maintained under a certain tension. Then, by rotating the nut set on the connecting pipe 1 76, the thread is rotated to make the moving member 74 move downward, and the downward movement of the moving member 74 compresses the spring 75, and through the connecting pipe 1 76 and the connecting pipe 2 77, the support plate 78 and the roller 79 thereon are also moved downward. At this time, the downward movement of the roller 79 will flatten the film. At the same time, due to its free rotation characteristics, it can be ensured that the film will not be wrinkled due to friction during the flattening process.

[0041] The servo motor 2 stops working, the slide bar 5 stops moving, and the sheet pressing member 7 remains in the position of flattening the film. After the sheeting is completed, the staff can remove the flattened film from the workbench 1 for subsequent operations. When it is necessary to sheet again, the servo motor 2 is started again, but the bidirectional screw rod 3 rotates in the opposite direction, which will cause the slide bar 5 to move in opposite directions, and the sheet pressing member 7 is reset to the initial position under the action of the spring 75. Through the above working principle, the device can achieve the close fit and flattening of the film, and keep the film under a certain tension through the rotation of the roller 79 and the slide bar 5, so as to avoid wrinkles in the film during the flattening process.
