Slot coater and method for adjusting slit

Abstract

The invention provides a slit type coating machine and a slit adjustment method. The slit type coating machine is provided with a driven shaft at each adjusting bolt; a drive shaft is arranged above each driven shaft; a motor drives the main shafts to rotate and then the drive shafts drive the driven shafts to rotate so as to realize torsion of the adjusting bolts. The whole adjustment process is finished under the control of the motor, and manual operation is unnecessary; the adjusting speed is fast; the controllability is strong; the accuracy rate is high; quantized operation and real-time operation can be realized; and the slit type coating machine and the slit adjustment method are not limited by the technical level of workers.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a slit coating machine and a slit adjustment method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Usually, the liquid crystal display panel consists of a color filter substrate (CF, Color Filter), a thin film transistor substrate (TFT, ThinFilm Transistor), a liquid crystal (LC, Liquid Crystal) sandwiched between the color filter substrate and the thin film transistor substrate, and a sealant frame (Sealant ), the molding process generally includes: the front-end array (Array) process (film, yellow light, etching ...

AI Technical Summary

Problems solved by technology

The width of the slit 4 is adjusted by tightening the adjusting bolt 3 or loosening the adjusting bolt 3. At present, the tightening or loosening of the adjusting bolt 3 is manually adjusted by the operator using a hexagonal wrench. When adjusting, the operator twists and adjusts The bolt 3 monitors the deformation of the lower end of the first nozzle split 1 or the second nozzle split 2 through a dial indicator to determine the adjustment level, and then passes through the film thickness measuring machine to measure the material film coated by the coating machine after adjustment. To check whether the adjustment is successful, repeat it many times until the adjustment is successful. This method requires the adjustment personnel to have high experience and high requirements for the technique. Only some trained personnel can implement it, and the required time for a single adjustment At the same time, it is difficult to return to the original state after adjustment, and the comparison between front and rear adjustments is relatively small, especially when the size of the product changes. At this time, manual adjustment by ordinary operators is difficult to achieve the accuracy required for production. Coating is necessary. It takes a lot of manpower and material resources to make on-site adjustments by the professionals of the coating machine manufacturer, and it cannot be adjusted if the professionals of the coating machine manufacturer are not in place, which seriously affects the normal production process and has poor flexibility.
