Description

Technical Field

[0001] This application relates to the field of silicon nitride ceramic substrate processing. Specifically, it relates to a cutting device for silicon nitride ceramic substrates. Background Art

[0002] Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. Silicon nitride has high strength. Especially hot-pressed silicon nitride is one of the hardest substances in the world, with properties such as high strength, low density, and high temperature resistance. Si3N4 ceramic is a covalent bond compound, and its basic structural unit is a [SiN4] tetrahedron. The silicon atom is located at the center of the tetrahedron, and there are four nitrogen atoms around it, located at the four vertices of the tetrahedron respectively. Then, in the form of sharing one atom for every three tetrahedrons, a continuous and strong network structure is formed in three-dimensional space. Silicon nitride ceramic needs to be cut during production and processing.

[0003] The patent document with the publication number CN220008364U discloses a cutting device for silicon nitride ceramic substrates, including a base, a lifting mechanism, a translation mechanism, and a cutting head. The lifting mechanism is installed on the base, and the output end of the lifting mechanism faces the base. The translation mechanism is installed on the output end of the lifting mechanism, and the cutting head is installed on the driving end of the translation mechanism. A first dust suction component is provided on the cutting head. When a cutting device for silicon nitride ceramic substrates is cutting, the silicon nitride ceramic substrate is placed on the base, the cutting head is started, and the cutting head is driven to move along the moving groove through the lifting mechanism and the translation mechanism. And while cutting, the second dust suction component moves in the moving groove following the cutting head to continue absorbing the dust under the silicon nitride ceramic substrate, while the first dust suction component moves following the cutting head to absorb the dust on the silicon nitride ceramic substrate, realizing the cleaning of the dust after cutting. Although the first dust suction component moves following the cutting head to absorb the dust on the silicon nitride ceramic substrate and realizes the cleaning of the dust after cutting in the above application document, when cutting the silicon nitride ceramic substrate, the silicon nitride ceramic substrate will move along, resulting in a decrease in the cutting accuracy of the silicon nitride ceramic substrate.
