Description

Technical Field

[0001] The utility model relates to the technical field of light shielding sheet processing, in particular to a light shielding sheet gluing device. Background Art

[0002] The shading sheet is an optical element used to regulate the amount of light. External light passing through the shading sheet can block the entry of unwanted light, thereby blocking the light exposure. The shading sheet is located between the two lenses. The shading sheet is used to block excess light to prevent stray light and improve the shooting effect of electronic equipment.

[0003] At present, in the production process of shading sheets, it is necessary to glue the shading sheets. The current method is to glue them between extrusion rollers. However, the gluing effect of the shading sheets using a single extrusion roller extrusion bonding method is unstable, and the phenomenon of glue deviation is prone to occur during multiple continuous processing. In addition, it is not suitable for gluing shading sheets of different sizes. Therefore, we propose a shading sheet gluing device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a light shielding sheet gluing device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Preferably, the extrusion mechanism includes two fixed columns fixed on both sides of the upper ends of the first fixed frame and the second fixed frame, the upper ends of the two fixed columns on the same side are commonly fixed with a fixed plate, the upper end of one of the moving blocks on the same side is fixed with two springs, and the upper ends of the two springs on the same side are commonly fixed to the lower end of a fixed plate.

[0008] Preferably, a limiting rod is fixed between opposite side walls of the first fixing frame and the second fixing frame.

[0009] Preferably, the squeezing roller is made of stainless steel.

[0010] Preferably, the crank handle is covered with a rubber sleeve.

[0011] In the present invention, when it is necessary to glue the shading sheet, the shading sheet is placed on the corresponding conveyor belt, and then the glue-dipped shading sheet is conveyed and squeezed and conveyed between the corresponding squeezing rollers as needed. When it is necessary to fully glue a large-sized shading sheet, three sets of squeezing rollers are used for squeezing and conveying, and the forward and reverse screws are driven to rotate by turning the crank, so that the two movable plates simultaneously drive the two sets of squeezing rollers on both sides to move toward the middle at the same time, thereby improving the squeezing effect. When it is necessary to glue a small-sized shading sheet, one set of squeezing rollers or two sets of squeezing rollers are used for gluing. When a single set is used for extrusion, the spring squeezes one of the moving blocks to achieve full extrusion, thereby ensuring the gluing effect.

[0012] The utility model can not only achieve full gluing of the shading sheet, but also adapt to the gluing requirements of shading sheets of different specifications, and at the same time can adjust the tightness of the gluing as needed, which greatly improves the processing efficiency, ensures the gluing quality, and enhances the practicability and stability of the gluing.
