Technical Field

The invention belongs to the field of preparation of ceramic substrates, and particularly relates to a powder coating machine for coating powder on the surface of a ceramic substrate.

Background

In the preparation process of the silicon oxide/silicon nitride ceramic substrate, ceramic substrate raw materials are required to be sintered into ceramic substrate clinker, the surface of the ceramic substrate raw materials is required to be coated with powder before sintering, and then the ceramic substrate raw materials are stacked and arranged in order. Therefore, the ceramic substrate raw material entering the sintering furnace is not easy to be adhered to each other in the sintering process, so that the ceramic substrate clinker with good quality is finally sintered.

The existing powder coating equipment has a plurality of defects, for example, the texture of the ceramic substrate raw material is crisp and light, and the existing mechanical arm mechanism cannot be suitable for transferring the ceramic substrate raw material to the conveying mechanism; for example, a large amount of adhesive powder separating slurry is scattered on the conveying mechanism in the powder coating process, and the subsequent conveying is influenced because the scattered adhesive powder separating slurry cannot be timely treated by the conventional conveying mechanism; for example, the ceramic substrates on the upper side after the ceramic substrates coated with the powder are stacked are easy to shift and fall in the conveying process, and the existing material receiving mechanism cannot avoid the situation.

The use process comprises the following steps:

1) the ceramic substrates are placed into the substrate stacking box body, the speed reducing motor drives the ejector rod to move upwards under the action of the lifting belt, the ejector rod enables the lifting base and the lifting base connecting strip to be lifted upwards, the ceramic substrates are lifted, the height of the ceramic substrates exceeds the upper edge of the substrate stacking box body, then the transverse moving motor drives the belt sliding block to move forwards along the horizontal belt, the vacuum suction cups are enabled to reach the positions right above the substrate stacking box body, the vertical air cylinders drive the vacuum suction cups to move downwards, and finally the ceramic substrates are adsorbed; after the ceramic substrate is adsorbed, the vacuum chuck returns to the initial position under the driving of the horizontal belt, a conveying mechanism can be arranged below the initial position, and the ceramic substrate can be placed on the conveying mechanism by the vacuum chuck.

2) The main conveyor is placed to the ceramic substrate on, main conveyer motor and belt drive main conveyer belt, the ceramic substrate is when powder mechanism is being laid to the process, it is on the ceramic substrate that powder mechanism sprays the powder thick liquid to the ceramic substrate, unnecessary powder thick liquid can spill on the main conveyer belt, the guiding panel is blown down to the powder thick liquid on the main conveyer belt to the air knife, partly powder thick liquid along being the flat guiding panel landing of slope to the recovery dish of retrieving the mechanism, another part falls to having the guide panel who connects the function greatly.
