A self-cleaning transport arm mechanism for glass substrates

Abstract

This invention discloses a self-cleaning transport arm mechanism for glass substrates. The bottom of the glass substrate transport arm assembly is configured with a suction cup structure for up-and-down buffering. The self-cleaning component on the upper surface of the glass substrate forms a rotating self-cleaning structure at the bottom of the glass substrate transport arm assembly. The up-and-down movement of the bottom of the glass substrate transport arm assembly forms a structure that drives the self-cleaning component on the upper surface of the glass substrate to rotate and clean itself. In use, the glass substrate transport arm moves down to contact the glass substrate. At this time, the glass substrate suction cup first contacts and fixes with the glass substrate. Then, the bottom arm of the glass substrate transport arm moves up. Through the cooperation of the spiral guide rail groove and the inner wall guide protrusion, the self-cleaning component on the upper surface of the glass substrate forms a rotating wiping and cleaning mechanism outside the glass substrate transport arm assembly. When the glass substrate is transported and hoisted, the bottom arm of the glass substrate transport arm moves down due to the gravity of the glass substrate. The above process is repeated.

Description

Technical Field

[0001] This invention belongs to the field of glass substrate handling technology, and specifically relates to a self-cleaning glass substrate handling arm mechanism. Background Technology

[0002] Glass substrates are one of the key basic materials in the flat panel display industry. A transparent conductive layer of In₂O₃ or SnO₂, known as an ITO film, is deposited on its surface. This layer is then processed using photolithography to create transparent conductive patterns. These patterns consist of pixel patterns and external lead patterns. Therefore, the external leads cannot be soldered using traditional methods; they must be connected using conductive rubber strips or conductive tapes. Scratches, cuts, or corrosion will render the device unusable.

[0003] The existing technology has the following problems: When handling glass substrates or placing them between boards, it is necessary to ensure that the upper surfaces of the boards are dust-free. At the same time, during handling, it is necessary to prevent dust from falling onto the upper board, because the contact between the boards will cause the dust to stick firmly between them, making subsequent cleaning incomplete or troublesome. It is also necessary to prevent debris from falling during handling. Therefore, there is an urgent need for a self-cleaning glass substrate handling arm mechanism to solve the above problems. Summary of the Invention

At this time, the rotation direction of the cleaning and wiping of the glass substrate upper surface self-cleaning assembly is opposite to the above direction. Through this structure and method, the upper surface of the glass substrate is cleaned during transport, preventing dust or other particles from adhering to the upper surface of the glass substrate during transport, effectively and reliably ensuring the cleanliness of the upper surface of the glass substrate during transport.
