Mask plate replacing device and method

Abstract

The invention discloses a mask plate replacing device and method. The mask plate replacing device comprises a substrate frame used for bearing a mask plate, an automatic locking mechanism which is arranged on the substrate frame and used for selectively locking or loosening the mask plate, and a supporting tray which is arranged below the substrate frame and used for lifting the mask plate. The substrate frame comprises a supporting tray hole, and the supporting tray can selectively enter and exit out of the supporting tray hole to lift up or put down the mask plate. According to the mask plate replacing device and method, the mask plate is arranged on the supporting tray through a clamping mechanism, the supporting tray is placed on the substrate frame, positioning of positioning pins reduces abrasion of the mask plate relative to fixing of threads, the automatic locking mechanism is stable and effective in fixing, and operation is convenient.

Description

technical field [0001] The invention relates to a sputtering coating machine, more specifically, to a mask replacement device and a replacement method of the sputtering coating machine. Background technique [0002] Sputtering coating machines are widely used in the coating process of TP, LCD, and OLED. In the coating process, there are many film-forming processes that do not require the entire substrate to be filmed. A close alignment system is used to deposit a film of a specific shape, and different product types use different masks. Every time the product model is replaced, the corresponding mask board will also be replaced, and after each replacement, the relative position of the mask board and the substrate frame must be kept unchanged during the film forming process, so as to produce The specific film pattern required. [0003] With the development of new technologies, the application of horizontal magnetron sputtering coating machines with mask plates and alignment...

Problems solved by technology

Especially for single-cavity coating, it takes more than 3 hours to replace each time. For continuous coating machines, the replacement is also a waste of time, and each time the substrate rack is taken from the machine, a substrate rack trolley must be used, which increases equipment costs and risk factor

Due to the large number of fastening screws, it is a waste of time to replace each mask, and repeated replacement of the fastening screws will cause the mask to fail, and a new mask needs to be replaced, which increases the cost; the entire replacement process is manual work done, inefficient
