[0038] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0040] As Figure 1As shown in the figure, the present application provides a film pressing mechanism for a film laminating machine, including an operating table 1. A placing component 2 is arranged on the operating table 1. The placing component 2 is used for placing the plate to be laminated. The placing component 2 can be a conveyor belt. A placing plate 21 is arranged on the conveyor belt. The conveyor belt is connected with a driving mechanism. Driven by the driving mechanism, the conveyor belt moves, driving the placing plate 21 placed on the conveyor belt to move, which is convenient for moving the plate with the film laminated to the collecting device after the film laminating is completed;

[0041] A film laminating component 3 is arranged on the operating table 1. The film laminating component 3 is arranged above the placing component 2. As Figure 1 shown, the film laminating component 3 is provided with a supporting part. The supporting part includes a supporting rod 31. The supporting rod 31 is fixed on the operating table 1. And the supporting rods 31 are arranged in pairs, distributed on both sides of the placing component 2. A moving component is arranged on the supporting rod 31. The moving component includes a sliding seat 32. The sliding seat 32 is slidably arranged on the supporting rod 31. The sliding seat 32 is adapted to slide along the supporting rod 31 in the vertical direction;

[0042] As Figure 2 shown, a cylinder 33 is also arranged on the operating table 1. The output end of the cylinder 33 is fixedly connected with the sliding seat 32. Therefore, driven by the cylinder 33, the sliding seat 32 can slide along the supporting rod 31;

[0043] As Figure 1 shown, the sliding seat 32 is connected with vertical plates 34. The vertical plates 34 are arranged in pairs. And there is an installation cavity between a pair of vertical plates 34. A film laminating mechanism is arranged in the installation cavity. The film laminating mechanism includes a film releasing roller 35. The film releasing roller 35 is rotatably connected with the vertical plates 34. The film releasing roller 35 is used for winding the film to be laminated. A pulling roller 36 is arranged below the film releasing roller 35. The pulling roller 36 is used for pulling the released film to prevent the film from bending. The film laminating mechanism further includes a film winding roller 37. The film winding roller 37 is arranged on the vertical plates 34. The film winding roller 37 is used for winding the waste film generated after the film laminating is completed;

[0044] It can be understood that the operations of film feeding, film winding and waste film winding are all driven by a power device. And the structure and content of this part can refer to the Chinese utility model patent with the publication number CN218907759U. The present application only makes a simple description and will not be elaborated here;

[0045] As Figure 2 shown, a pressing structure 4 is also arranged between the vertical plates 34. The pressing structure 4 is used for pressing the plate after the film laminating is completed, so that the film adheres to the surface of the plate and discharges the bubbles that may appear during the film laminating process, improving the film laminating quality;

[0046] As Figure 3As shown, the pressing structure 4 includes a mounting plate 41 fixedly installed on the vertical plate 34. A sliding groove 42 is provided on the mounting plate 41. The sliding groove 42 is arranged in the vertical direction. A slider 43 is slidably arranged in the sliding groove 42. The slider 43 is adapted to slide in the sliding groove 42, and a fixing component is provided on the slider 43 to fix the slider 43 in a proper position;

[0047] The fixing component includes a fixing hole provided on the slider 43, and a bolt is arranged in the fixing hole. The fixing hole is used to be fixed by the bolt after the slider moves into place. At the same time, the slider 43 has a protrusion, and a mounting hole is provided at the protrusion. A fixing shaft 44 is slidably arranged in the mounting hole;

[0048] As Figure 3 shown, one end of the fixing shaft 44 is provided with a pressure roller seat 45. The pressure roller seat 45 is fixedly connected to the fixing shaft 44. A pressure roller 46 is connected by bearings in the pressure roller seat 45. The pressure roller 46 is used to contact the surface of the device with the film attached, so as to press the film and the device, so that the film adheres to the surface of the device. And before the film sticking starts, the pressure roller 46 and the placing component 2 can generate a gap by moving the fixing shaft 44. This gap is used to accommodate the film to be stuck and the device;

[0049] In order to adapt to devices with a smaller thickness and increase the pressing force of the pressure roller 46, as Figure 3 shown, a spring 47 is sleeved on the fixing shaft 44. The spring 47 is arranged between the slider 43 and the pressure roller seat 45. In the normal state, the spring 47 is in a natural state, that is, in a state of neither being compressed nor elongated. During the pressing process, the thickness of the device and the film will push the pressure roller 46 and the pressure roller seat 45 upward, so that the pressure roller seat 45 generates a squeezing force on the spring 47, and the spring 47 starts to contract. The contracted spring 47 will generate an elastic force in the direction of the pressure roller 46, so that the pressure roller 46 closely adheres to the surface of the device to be film-stuck, thereby improving the film-sticking quality;

[0050] When the thickness of the device to be film-stuck is small, it cannot generate an upward pushing force on the pressure roller 46 and the pressure roller seat 45. Therefore, the film-sticking effect is not good. At this time, the position of the slider 43 needs to be moved so that it moves in the direction of the pressure roller 46, so that the spring 47 is compressed to generate an initial elastic force, and this elastic force is applied to the pressure roller 46. When film-sticking the device to be film-stuck with a smaller thickness, the initial elastic force will press the pressure roller 46 onto the surface of the device to be film-stuck, improving the film-sticking effect.

[0051] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
