Abstract
Description
Technical Field
[0001] The utility model relates to the field of gas sensors, in particular to the spraying field in the microelectronics field, and specifically refers to a spraying mask tooling device. Background Technique
[0002] Gas sensors mainly include sensors based on optical principles, catalytic combustion principles, electrochemical principles, and semiconductor principles. Among them, different principle sensors involve the preparation of catalytic slurries, so that the sensors can have responses. After the catalytic slurries are prepared, they are coated onto substrates or supports through processes such as screen printing, spraying, drop gluing, and dipping, so that they are firmly adhered to the substrates or supports. Among them, the spraying process has the advantages of high production efficiency, being suitable for manual and automated production, and wide application range. It is a relatively common and popular way of slurry coating. Spraying mainly disperses the slurry into uniform and fine droplets by means of a spray gun or atomizer with the help of pressure or centrifugal force and coats them on the surface of an object, which can be divided into air spraying, airless spraying, electrostatic spraying, etc.
[0003] During the spraying process, it is necessary to disperse the slurry. However, different sensors use different spraying slurries and spraying shapes, etc. Therefore, a mask plate is needed to block it, so that the sprayed substance presents the desired shape. However, the mask plate is often directly placed on the substrate or support. The catalytic layer in the gas sensor is often relatively thin, so the thickness requirement for the mask plate is relatively high. When the mask plate is thin, it is easy to deform during the spraying process, resulting in an unattractive and incomplete sprayed pattern. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art and provide a spraying mask tooling device that is not easy to deform, easy to spray, and has a relatively wide range of applications.
[0005] In order to achieve the above purpose, the spraying mask tooling device of the utility model is as follows:
[0006] The spraying mask tooling device, its main feature is that the device includes an upper plate, a lower plate, and a mask plate. The upper plate is installed on the lower plate, and the mask plate is placed between the upper plate and the lower plate. The upper plate includes a frame, large threaded holes on the upper plate, small threaded holes on the upper plate, and cross beams. The frame includes a left side, a right side, and a rear side. More than 5 large threaded holes on the upper plate are provided on the frame, and the upper plate, the lower plate, the cross beams, and the mask plate are fixed through the large threaded holes on the upper plate. There are more than 2 cross beams in the middle of the upper plate, and at least one small threaded hole on the upper plate is provided on each cross beam.
[0007] Preferably, the length of the cross beam is flush with the frame, the width matches the mask plate, and is less than the interval width between two columns of cutouts of the mask plate.
