Embodiment 3

[0045] Embodiment 3 The influence of the position of the glue supply container on the state of glue application among the present invention

[0046] Such as Figure 4 As shown, suppose that in the connecting device formed by the glue supply container (1) and the glue spraying device (2), the vertical distance between the glue spraying port and the lowest point of the connecting device is h 22 , when the glue supply container is in different positions A, B, and C, the vertical distances between it and the lowest point of the connector are h A 、h B 、h C . When the glue supply container is higher than the glue spraying device in the vertical direction, that is h A > h 22 , the pressure difference generated by the height difference of the liquid level on the lowest point of the connector will promote the glue liquid to flow to the glue spraying device. When the positions of the glue supply container and the glue spraying device are unchanged, the pressure difference remains c...

Abstract

The invention provides a glue supply device used for continuous, stable and uniform glue coating, and a glue liquid coating method, and belongs to the field of continuous production advection film coating. The glue supply device comprises a glue supply container, a glue spraying device, a low-position glue storage container and a liquid conveying device. The glue supply container comprises a glueinlet, a glue outlet and a glue supply area. The glue spraying device comprises a glue supply opening and a glue coating opening. The liquid conveying device comprises a liquid inlet and a liquid outlet. The liquid outlet of the liquid conveying device is connected with the liquid inlet of the glue supply container, the glue outlet of the glue supply container is connected with the glue supply opening of the glue spraying device, the low-position glue storage container is connected with the liquid inlet of the liquid conveying device, and all connection mentioned above is pipeline connection.The height of the liquid level the glue supply area in the glue supply container is stable and controllable, the highest point of the liquid level is higher than the highest point of the liquid levelof the glue spraying opening in the glue spraying device in the vertical direction, the low-position glue storage container is connected with the liquid inlet of the liquid conveying device, and all connection mentioned above is pipeline connection. The height of the liquid level of the glue supply area in the glue supply container is stable and controllable, the highest point of the liquid levelis higher than the highest point of the liquid level of the glue spraying opening in the glue spraying device in the vertical direction, stable pressure is provided for glue liquid flowing of the gluespraying opening in the glue spraying device, and therefore continuous, stable and uniform glue coating can be achieved for meniscus film coating devices.

Description

technical field [0001] The invention belongs to the field of making stable and uniform single-sided continuous advection coating films, and in particular relates to an adjustable automatic, stable and uniform glue supply device and a glue coating method, which are applied to meniscus glue coating equipment. Background technique [0002] At present, many large-diameter optical switching devices, optical lenses, and optical displays need to be coated with a single film, some require a single-sided multi-layer film, and some require a double-sided heterogeneous film. Moreover, industrial coating requires continuous efficiency. At present, continuous coating of single-sided optical thin films is a common physical method in industry, such as magnetron sputtering is a commonly used method. The wet chemical method currently has a lifting method, but it cannot coat a single film, and the continuous film coating is also limited by equipment to a certain extent; although the spin coa...
