Problems solved by technology

[0006] However, the above method adopts cold roll embossing, which easily leads to high deformation resistance of the material, and the material flows and deforms at a micro scale. Due to the existence of the size effect, the influence of the material type, grain size and orientation will cause the material to flow fully during the micro deformation process. The shape is uneven, the process parameters are unstable, and the quality of the imprinted product is not high

Embodiment 1

[0041] like figure 2 As shown, the light-transmitting mold 3 and the light-transmitting roller 4 are arranged separately, the light-transmitting mold 3 is a flat mold, placed on the upper surface of the material 2, and the light-transmitting mold 3 is transported along the support synchronously with the material 2 When the mechanism moves in the running direction, the light-transmitting roller 4 rolls relative to the upper surface of the light-transmitting mold 3 .

[0042] The supporting and conveying mechanism is a linear motion platform 5, and the linear motion platform 5 is driven by the first drive mechanism 8 to perform linear reciprocating motion. In any one of them, the first driving mechanism 8 is a servo motor or a linear motor.

[0043] In this embodiment, the following steps are performed when laser heating roller embossing is performed on the material 2:

[0044] The first step is to adjust the light-transmitting roller 4 to a suitable height through the rolling ...

Embodiment 2

[0050] like image 3 As shown, based on Example 1, the light-transmitting mold 3 is replaced, specifically: the light-transmitting mold 3 is arranged around the outer roller wall of the light-transmitting roller 4, and is integrally formed with the light-transmitting roller 4, and is transparent During the rotation of the light roller 4 , the light-transmitting mold 3 on it acts on the surface of the material 2 . Roll stamping has the following steps:

[0051] The first step is to adjust the height of the light-transmitting roller 4, and place the material 2 that needs to be rolled on the linear motion platform 5;

[0052] The second step is to adjust the rolling gap adjuster 11, so that the light-transmitting roller 4 moves vertically downward, and the microstructure on the surface of the light-transmitting mold 3 on the outer ring of the light-transmitting roller 4 is pressed into the surface layer of the material 2 to the required rolling depth;

[0053] The third step is...

Embodiment 3

[0055] like Figure 4 , Based on Example 1, the linear motion platform 5 is replaced with a rotating roller 6, that is, the supporting and conveying mechanism is a rotating roller 6, and the rotating roller 6 is driven to rotate by the first driving mechanism 8, and the rotating roller 6 and the light-transmitting roller 4 are rotated. The shafts are parallel to each other, the rotating roller 6 is mounted on the frame 7 through a bearing, and the bearing is any one of a hydraulic bearing, a pneumatic bearing or a magnetic bearing, and the first driving mechanism 8 is a servo motor or a brushless motor. , hydraulic motor or pneumatic motor. Roll stamping has the following steps:

[0056] The first step is to adjust the height of the light-transmitting roller 4, place the material 2 that needs to be rolled on the rotating roller 6, and place the light-transmitting mold 3 on the top of the material 2, so that the light-transmitting mold 3 has a side with microstructure features...

Abstract

The invention discloses a laser heating roller type micro-imprinting device, comprising a frame, a supporting conveying mechanism, a laser, a light-transmitting mold, a light-transmitting roller and a rolling gap adjusting mechanism. The light-transmitting roller can be rotatably installed on the rolling gap adjustment At the lower end of the mechanism, the laser is installed above the transparent roller. The central axis of the transparent roller and the conveying direction of the supporting conveying mechanism are perpendicular to each other. The transparent roller acts on the surface of the transparent mold, forming a rolling pressure between the transparent mold and the supporting and conveying mechanism. The material is placed in the rolling gap, and the beam emitted by the laser acts on the material through the light-transmitting roller and the light-transmitting mold in sequence; the present invention reduces the imprinting force through the near-linear contact between the light-transmitting roller, the light-transmitting mold and the material. , using laser non-contact heating of the surface of the fine forming area of ​​the material to improve the forming stability and forming accuracy of the material; the traditional rolling process and the plane embossing process are combined to improve the embossing efficiency.

Description

technical field [0001] The invention relates to the technical field of micro-fabrication equipment, in particular to a laser heating roller type micro-imprint device. Background technique [0002] Functional surface microstructure refers to the characteristic size range of the product surface microstructure is 0.01 ~ 1mm, which is between the microscale and the macroscale (called meso scale). These surface microstructures can enhance product functions and improve products. performance, and optimize product economy and ecological environmental protection, especially large-area functional surface microstructures such as microchannels, microribs, micropits, etc. There are significant advantages in terms of rate and so on.
