Embodiment 1

[0044] In a typical embodiment of the present invention, such as figure 1 As shown, a high-precision scraping equipment with adjustable scraping angle is proposed, which includes an electric translation platform 100, a scraper height adjustment mechanism 200, a scraper angle adjustment mechanism 300, a lifting table 400, an electric translation platform 100, and a scraper height adjustment mechanism. Mechanism 200, scraper angle adjustment mechanism 300, and lifting workbench 400 are all fixed in the cabinet. The lifting table 400 is connected with the electric translation table 100, and the electric translation table drives the lifting table to move in the horizontal direction; the scraper angle adjustment mechanism 300 is arranged on the top of the scraper height adjustment mechanism 200, and the scraper height adjustment mechanism 200 can drive the scraper angle adjustment mechanism 300 Move up and down to adjust the height of the scraper, the scraper angle adjustment mecha...

Embodiment 2

[0072] In this embodiment, compared with Embodiment 1, the difference is that: the scraping angle is 15°, the worm shaft 330 is rotated by manual rotation of the worm shaft, and the angle of the scraper 341 is adjusted to a desired angle.

Embodiment 3

[0074] In this embodiment, compared with the embodiment 1, the difference is that: the scraping thickness is 15 μm, and the differential head 210 is rotated to adjust to the desired height.

Abstract

The invention discloses high-precision blade coating equipment and method with adjustable blade coating angle. The equipment comprises a scraper angle adjusting mechanism connected with a scraper andcapable of adjusting the scraper angle, and a scraper height adjusting mechanism connected with the scraper angle adjusting mechanism and comprising an inclined block capable of moving horizontally, the top surface of the inclined block is an inclined surface, the bottom of the scraper angle adjusting mechanism is connected with a top plate, the bottom of the top plate is connected with a roller through a supporting rod, the roller is in contact with the top surface of the inclined block, and the inclined block moves to drive the scraper angle adjusting mechanism to lift so as to adjust the height of the scraper.

Description

technical field [0001] The invention belongs to the technical field of flexible electronics, and in particular relates to a high-precision scraping coating device and method with adjustable scraping angle. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Field-effect transistors are active devices based on the controlled injection of free carriers into semiconductors. An Organic Field-Effect Transistor (OFET) uses an organic semiconductor material as a transport layer. Compared with inorganic semiconductors, the unique flexibility of organic semiconductors makes them compatible with flexible substrates, thereby realizing flexible and stretchable circuits, which have great potential application value in wearable devices, medical monitoring, electronic skin, etc. The morphology and microstructure of the organic semiconductor layer play a very import...
