Mask bearing device and evaporation device

Abstract

The invention relates to the technical field of production equipment for display devices and discloses a mask bearing device and an evaporation device. The mask bearing device comprises a bearing frame. The bearing frame comprises two parallel support plates. A walking gap is formed between the two support plates. Multiple foundation stop dogs higher than the support face are arranged on each support plate. A first stop dog is formed on the portion, corresponding to the second end of the walking gap, in each support plate. A first end facing the walking gap and a mask posture correction face in the direction perpendicular to the extending direction of the walking gap are formed in each stop dog, and in the direction perpendicular to the support face, the heights of the posture correction faces are higher than that of the foundation stop dogs. According to the mask bearing device, the postures of masks on a mask conveying trolley are adjusted by the first stop dogs so that the masks canbe precisely put on the bearing frame, secondary adjustment of the mask positions is avoided, the working efficiency is improved effectively, and the productivity can be improved.

Description

Technical field [0001] The present invention relates to the technical field of manufacturing equipment for display devices, in particular to a mask plate carrying device and an evaporation device. Background technique [0002] The high-precision metal mask mode is now a common way to prepare display devices. The organic electroluminescent material is vapor-deposited on the backplane according to a predetermined procedure by vapor deposition, and red, green, and blue are vapor-deposited using the patterns on the mask. Organic matter to the specified location. In the current production process, the mask on the carrier is picked up and placed by a manual car. However, due to the uncertainty of the process direction of the manual car, it often happens that the mask cannot be accurately placed in the definite slot of the carrier. In the position, secondary adjustments are also required, which causes problems such as reduced work efficiency of the preparation process and reduced produ...

Problems solved by technology

In the current production process, the mask plate on the carrier is picked and placed by a manual cart, but due to the uncertainty of the direction of the process of artificially pushing the manual cart, it often happens that the mask plate cannot be placed accurately in the determined slot of the carrier frame Within the position, a secondary adjustment is required, which leads to problems such as reduced work efficiency and reduced production capacity in the preparation process.
