Scribing device for glass substrate coating

Abstract

The invention discloses a scribing device for glass substrate coating. The scribing device comprises a positioning support, a first guide through groove is formed in the upper end of the positioning support, a top plate is fixed to the upper side of the positioning support, a second guide through groove penetrating through one end of the top plate is formed in the top plate, and scribing needle assemblies are arranged on the positioning support and the top plate; each scribing needle assembly comprises a positioning column, a second positioning concave hole is formed in the second guide through groove, a first positioning concave hole is formed in the first guide through groove, a central threaded hole is formed in the positioning column, a scribing needle is in threaded connection with the central threaded hole, a placement hole is formed in the positioning column, and an adjusting rod is inserted into the placement hole; a second adjusting block and a first adjusting block are formed on the adjusting rod, a second positioning ball head is formed on the second adjusting block, the second positioning ball head is embedded in the second positioning concave hole, a first positioning ball head is formed on the first adjusting block, and the first positioning ball head is embedded in the first positioning concave hole. The scribing needle assembly is convenient to add, and meanwhile, the position of the scribing needle is convenient to adjust and position.

Description

Technical field: [0001] The invention relates to the technical field of vacuum coating equipment, in particular to a scribing device for coating a glass substrate. Background technique: [0002] Coated glass, also known as reflective glass, is a glass that is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass and meet certain specific requirements. In order to meet specific requirements, a glass substrate does not necessarily have to be coated on the entire area. In this way, before coating, the staff needs to mark the coating area on the glass substrate. However, manual scribing is often inefficient and less accurate, so it needs Design a device specially designed for scribing glass substrates. This type of device needs to be equipped with a scribing mechanism for scribing. The position of the scribing needle in the scribing mechanism needs to be adjustable. At the same time, some ...

In order to meet specific requirements, a glass substrate does not necessarily have to be coated on the entire area. In this way, before coating, the staff needs to mark the coating area on the glass substrate. However, manual scribing is often inefficient and less accurate, so it needs Design a device specially designed for scribing glass substrates. This type of device needs to be equipped with a scribing mechanism for scribing. The position of the scribing needle in the scribing mechanism needs to be adjustable. At the same time, some glass substrates are equipped with multiple lines. Multiple scribing needles are required in the organization to complete the scribing work at one time
