The invention relates to the field of organic light-emitting display, and provides a metal mask welding fixture and a metal mask welding method. The metal mask welding fixture comprises a stretching base, a stretching executing unit and an attracting device, wherein the stretching base is provided with a first side surface and a second side surface which are opposite to each other, a preformed hole which runs through the first side surface and the second side surface is formed in the stretching base, the stretching executing unit is used for stretching a metal mask which is located above the first side surface, and the attracting device is arranged in the preformed hole and used for releasing attracting force so as to attach the stretched metal mask to a bearing frame and maintain the relative position relationship of the metal mask and the bearing frame. By means of the metal mask welding fixture and the metal mask welding method, the problems of pseudo welding, poor welding spot morphology, reduced welding spot strength, welding spot sealing-off and the like which possibly occur on the metal mask in the welding process can be prevented.
Description
technical field [0001] The present application relates to the field of organic light-emitting displays, and in particular to a metal mask welding tool, a robot, an elastic body for the metal mask welding tool, and an object sensing method. Background technique [0002] Currently, due to OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display has the advantages of self-illumination, wide viewing angle, low power consumption, high contrast, high color gamut, flexible display, low power consumption, and extremely high response speed, etc., so received more and more attention. [0003] OLED displays can be classified into PMOLED (Passive matrix organic light emitting diode, passive organic light emitting diode) display and AMOLED (Active-matrix organic light emitting diode, active organic light emitting diode) display according to the driving method. [0004] Among them, the production process of the AMOLED display is as follows: the OLED material is evaporate...
