Description

Stackable and cut acrylic sheet structure

This creation is a stackable acrylic sheet structure, especially a laser that cuts a large number of processed bodies in a single shot to improve the efficiency of fabrication, processing and output. Do not stick to each other when heated.

According to the conventional processing of Polymethylmethacrylate (PMMA), most of them are mechanically processed, that is, the steps of cutting, drilling, planing, engraving, grinding and polishing the acrylic sheets respectively. The acrylic shape is shaped as the shape to be formed; however, in terms of the cutting step, the cutter is used for cutting, and the cutting process is quite time consuming, and a large amount of dust is generated, which greatly affects the environment and the operator. The health, in addition, the rough surface after cutting with a cutter, the post-processing process is extremely complicated.

Therefore, a laser cutting machine for performing acryl is provided for transmitting a laser beam for thermal cutting, whereby a laser is converted into an approximately parallel beam having a very small divergence angle by a Resonator. Then, after widening the beam with a Beam Amplifier, the beam is concentrated on the acryl by a focusing lens, thereby heating and sublimating the acryl, and in order to prevent burning due to overheating during the cutting process, Spraying a gas that is inert or slow in reaction rate, such as helium, argon or nitrogen, to isolate the air; thereby, the overall processing procedure of the acrylic can be greatly shortened, and the edge after cutting is smooth, and Dust is not easy to be generated during processing, which can effectively avoid environmental pollution and affect the health of the operator; however, in laser cutting, only a single acrylic cutting can be performed in a single time, because it is mainly for pressing The force is heated to be sublimated by the heat. Therefore, during the cutting process, the cutting surface of the acrylic will partially melt due to heat, so if the acrylic is stacked and cut, it will result in The adhesion between the crescennes is so hard that it is difficult to separate the acrylics of the stack, and it will also affect the quality of the acrylic. If the acrylic cutters are used one by one, it is quite time consuming, which will make the finished product difficult to quantify. Producer.

In view of this, the creator specially researched and improved the cutting of acrylic, and improved the above problems with a better design, and after long-term research and development and continuous testing, the creation of this creation began.

Therefore, in order to solve the problem of using laser-cutting acrylic, it is impossible to carry out quantitative cutting of the stack, and it is only possible to cut a single acrylic in a single time, which affects the yield of the finished product.

In order to achieve the above object, our creator provides a stackable cut acrylic sheet structure comprising: a plurality of processed bodies stacked one on another, and each of the processed bodies is provided with a corresponding spacer layer In order to separate the processed body, the spacer layer is such that when the processed body is cut, the processed bodies are not bonded to each other by heat fusion.

According to the acrylic plate structure described above, the processed body is Polymethylmethacrylate (PMMA).

According to the acrylic plate structure described above, the spacer layer is mainly a thin layer of paper maker.

According to the acrylic plate structure described above, the spacer layer is mainly a thin layer of paper maker.

According to the acrylic plate structure described above, a laser cutting device corresponding to cutting the processed body by the stacking direction of the processed body is further included, and the depth of focus of the laser cutting device corresponds to the processed body and the interval The thickness of the layer stack.

It is from the above description and settings that it is obvious that this creation has the following several advantages and functions, which are detailed as follows:

1. The creation of the spacer layer allows the laser cutting device to cut a plurality of stacked processed bodies in a single pass, and the partition between the processed bodies during the laser cutting process is blocked by the spacer layer. It does not stick to adjacent processing bodies, which can improve the quality of processed products and effectively improve the efficiency of manufacturing, processing and output.

This creation is a stackable and cut acrylic sheet structure, its implementation means, characteristics and functions. Several preferred and feasible examples are described in detail below with reference to the drawings. This creation.

First, as shown in Figure 1, this creation is a stackable cutting acrylic sheet structure that includes:

a plurality of processed bodies 1 which are stacked with each other (PMMA), which are arranged one above another, and a corresponding spacer layer 2 is respectively disposed between the processed bodies 1 to separate the processed body 1, the spacer layer 2, when the processed body 1 is cut, the processed bodies 1 are not bonded to each other by heat fusion, and the spacer layer 2 is mainly a thin layer of paper maker;

Corresponding to the laser cutting device 3 for cutting the processed body 1 by the stacking direction of the processed body 1, and the depth of focus (depth of field) of the laser cutting device 3 corresponds to the thickness of the stacked body 1 and the spacer 2 By.

As shown in FIG. 1 , the user can select the number of the processed bodies 1 to be stacked according to requirements, and the spacer layer 2 is disposed between the two processed bodies 1 to penetrate the spacer layer 2 . The processed body 1 is separated, and the thickness T of the processed body 1 and the spacer 2 as a whole is calculated, wherein the spacer layer 2 is prevented from being excessively affected by the thickness T of the processed body 1 Thinner papers are preferred.

As shown in FIG. 2, it is assumed that it is the original focus depth L ₀ of the laser cutting device 3, and the focus of the laser cutting device 3 will affect the speed and quality of the cutting, wherein the smaller the focus, The density of its laser power will also increase, and the size of the focus is as shown in Mathematical Formula 1:

[Math 1]

Where d is the focus size, M is the beam propagation parameter of the laser cutting device 3, λ is the laser light wavelength of the laser cutting device 3, D is the diameter of the incident laser, and f is the focal length of the laser cutting device 3 .

In order to enable the laser cutting device 3 to cut the stacked processed body 1 at a time, the depth of focus is required to correspond to the thickness of the entire processed body 1 and the spacer layer 2, and the depth of focus generally refers to a change in the focus size of 5%. The distance of the range (that is, the focus size of 1 to 1.05 times) can be simplified to the following mathematical formula 2:

[Math 2]

Therefore, the focus depth can be adjusted by adjusting the above parameters, so as shown in FIG. 3, the focus depth L ₁ can be adjusted to correspond to the thickness T of the processed body 1 and the spacer layer 2 as a whole. The processed body 1 and the spacer layer 2 can be cut.

In the process of laser cutting, the laser cutting device 3 covers the entire depth of the processed body 1 and the spacer layer 2, so that the light beam is concentrated on the processed body 1 and the spacer layer 2 through the focusing lens to process the processed body. 1 and the spacer layer 2 is heated and sublimated, since the cut surface of the processed body 1 is heated to form a liquid state, and the hot melt processed body 1 is not separated by the adjacent processed body 1 because it is separated by the spacer layer 2, so when the cutting is completed After that, only the spacer layer 2 is torn off, and the processed body 1 having the same shape and no mutual adhesion can be obtained, thereby clearly showing that the creation of the plurality of processed bodies 1 can be performed in a single operation, and the system can be improved. The efficiency of production, processing and output, as well as the quality of finished products.
