Description

Technical Field

[0001] The present invention relates to the technical field related to optical film cutting, and in particular to an automated processing equipment for producing optical films. Background Art

[0002] Optical films are divided into reflective films, anti-reflection films, filter films, optical protective films, polarizing films, spectroscopic films and phase films according to their applications. Optical reflective films are used to increase the reflectivity of mirror surfaces and are often used to manufacture reflective, refracting and resonant cavity devices. Optical anti-reflection films are deposited on the surface of optical components to reduce surface reflection and increase the transmission of optical systems, and are also called anti-reflection films. Optical filter films are used for spectral or other optical separation, and there are many types and complex structures. Optical protective films are deposited on the surface of metals or other soft and easily corroded materials or films to increase their strength or stability and improve their optical properties.

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-5As shown, an automated processing equipment for producing optical thin films comprises: a base 1, a pair of horizontal guide bars perpendicular to each other and fixedly mounted on the base 1, at least one pressing member 2 mounted on the base 1 and capable of vertical movement, and a pair of sliding arms 3 arranged parallel to the guide bars and capable of horizontal movement on the pressing member 2 in a direction perpendicular to the length direction of the guide bars, each sliding arm 3 is equipped with a pair of cutting units arranged in a symmetrical state, and each of the guide bars is movably equipped with a vertical limit plate 4;

[0031] The cutting unit includes an adjusting sleeve 5 slidably mounted on the sliding arm 3, a first locking bolt 6 mounted on the adjusting sleeve 5, a mounting plate 8 fixedly connected to the adjusting sleeve 5 via a first mounting frame 7, a fan-shaped pressure plate fixedly connected to the mounting plate 8 via a second mounting frame 9 and located below the mounting plate 8, a motor 10 mounted on the mounting plate 8, a horizontal rotating arm 11, a transmission mechanism connecting the rotating arm 11 and the output shaft of the motor 10 for driving the rotating arm 11 to swing back and forth around the axis of the fan-shaped pressure plate and driving the rotating arm 11 to move gradually downward, and a cutting knife 12 mounted on the rotating arm 11 via a mounting mechanism.

[0032] In the above technical scheme, the two side edges of the stacked film are respectively in contact with two limit plates 4, and a pair of limit plates 4 makes the edges of the film stacked neatly, and the lower pressure piece 2 moves downward so that the fan-shaped pressure plate is pressed on the corners of the film. The four groups of cutting units on the two sliding arms 3 correspond to the four corners of the film respectively. The motor 10 is started and the rotating arm 11 is driven to rotate around the axis of the fan-shaped pressure plate through the transmission mechanism. The cutting knife 12 can cut the edge of the film into a rounded corner. While the rotating arm 11 swings back and forth, the rotating arm 11 will also move downward, so that the cutting knife 12 continues to move downward, and the cutting knife 12 can cut the stacked film layer by layer.

[0033] When the specifications of the films to be cut are different, first adjust the position of the slide arm 3 on the lower pressure piece 2, and then adjust the position of the adjustment sleeve 5 on the slide arm 3, so that the positions of the four cutting units can be adjusted, so that the four cutting units can cut the edges and corners of the films at the same time, which is efficient and can cut films of different specifications, and is highly practical.

[0039] In the above technical solution, when adjusting the distance between the cutting knife 12 and the rotation axis of the rotating arm 11, the fan-shaped pressure plate is also adjusted. By increasing or decreasing the number of the first arc strips 18, the outer diameter of the fan-shaped pressure plate can be increased or decreased, and adjusted to match the required rounded corner diameter for cutting.

[0040] Open the locking mechanism and rotate the corresponding first arc strip 18 along the axial direction of the central connecting disk 17 so that the arc clip 21 is moved out of the corresponding arc clip groove 20, and the first arc strip 18 can be removed; insert the arc clip 21 into the arc clip groove 20 of the outermost first arc strip 18 along the axial direction of the central connecting disk 17, and then fix the two adjacent first arc strips 18 by the locking mechanism to complete the assembly of the first arc strip 18.
