Description

A device for sticking film

technical field

The utility model relates to a device for pasting films.

Background technique

An optical sheet formed by laminating multiple layers of liquid crystal film, polarizing film, retardation film, luminance enhancement film, electromagnetic wave shielding film, etc. on the surface of a display panel, optical device lens, etc. In order to bond two thin films together, it is necessary to position each film accurately, and to prevent the entry of air bubbles while overlapping without causing wrinkles.

In the early days, the lamination of the film was mostly manual lamination. The alignment of the film layer and the carrier position was determined manually, and the lamination pressure was controlled by the operator's experience. This method is inefficient, and the bonding quality is not easy to guarantee, which greatly depends on the proficiency of the operator. Therefore, a semi-automatic fitting device appeared later. But the general bonding efficiency is not high.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for pasting films.

The utility model is achieved through the following technical solutions:

A device for pasting films, comprising an upper workbench and a lower workbench parallel to the upper workbench, grooves and through grooves parallel to the upper workbench are formed on both sides of the upper workbench, and inside the grooves There is a moving rod that can move in the groove, the moving rod is fixedly connected to the vertical rod passing through the through groove, the vertical rods on both sides of the upper worktable are fixedly connected to a rotating shaft, and a film roll is wound around the rotating shaft One side is also connected to a rubber roller parallel to the rotating shaft and located below the rotating shaft through a connecting rod, and the film reel can rotate around the rotating shaft.

In the above-mentioned device for sticking film, the rubber roller can rotate around the rotating shaft through the connecting rod.

In the above-mentioned device for pasting films, the upper workbench is supported by a column and moves up and down driven by a cylinder.

In the above-mentioned device for pasting films, positioning holes are arranged on the lower workbench.

In the above-mentioned device for pasting films, a CCD detection and positioning system is arranged on the lower workbench.

In the above-mentioned device for pasting films, the moving rod is driven by a motor.

The beneficial effects achieved by the utility model:

The device of the utility model is easy to use. The film reel is obtained by rolling the film on the cylinder, and the film reel can rotate around the rotating shaft. The film is pressed and pasted on the object to be filmed by the rubber roller, and only the moving rod drives the rotating shaft to move. , so as to complete the film sticking process, the film sticking effect is good, and no air bubbles will be generated due to the pressing effect of the rubber roller.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in the figure, a device for pasting films of the present invention includes an upper workbench 1 and a lower workbench 2 parallel to the upper workbench 1, and both sides of the upper workbench 1 are provided with 1 Parallel groove 3 and through groove 4, there is a moving rod 5 that can move in the groove 3 in the groove 3, and the moving rod 5 is fixedly connected to the vertical rod 6 passing through the through groove 4, and the upper The vertical rods 6 on both sides of the workbench 1 are fixedly connected to a rotating shaft 7, on which a film reel 8 is wound, and one side is connected to a rubber roller 10 parallel to the rotating shaft 7 and located below the rotating shaft 7 through a connecting rod 9 , the film reel 8 can rotate around the rotating shaft 7 .

The rubber roller 10 can rotate around the rotating shaft 7 through the connecting rod 9 . The upper workbench 1 is supported by a column 11 and moved up and down driven by a cylinder (not shown). Positioning holes 13 are arranged on the lower workbench 2 . A CCD detection and positioning system 14 is arranged on the lower workbench 2 . The moving rod 5 is driven by a motor 15 .

The rubber roller 10 can rotate around the rotating shaft 7 through the connecting rod 9, which is convenient to operate, and can be put away when the film is not needed; the upper workbench 1 moves up and down under the drive of the cylinder (not shown), and the rubber roller can be adjusted 10 the distance from the lower workbench 2; the positioning hole 13 on the lower workbench 2 can be used for positioning to ensure the accuracy of fitting; the CCD detection and positioning system 14 on the lower workbench 2 is used for detection and positioning to improve accuracy; The moving rod 5 is driven by a motor 15, without manual operation, and has a high degree of automation.

When the device of the present invention is in use, the object to be filmed is placed on the lower workbench 2, and the rubber roller 10 presses the film on the film reel to one end of the object, and the film reel 8 is driven by the moving rod 5 to rotate and the rubber roller 10 move, so that the film is pressed on the object, and the film sticking process is completed.
