Detection jig and detection method thereof

Abstract

The invention discloses a detection jig and a detection method thereof. By disposing a supporting frame having a first guide rail extending along a first direction and at least one sliding guide railextending along a second direction, disposing the sliding guide rails on the first guide rail and locating the sliding guide rails on the same horizontal plane, a plurality of magnetic detection probes are arranged on the sliding guide rails, the magnetic detection probes are located at the same height, so that the magnetic detection probes collect the magnetic induction intensity of magnetic isolation plates at the same height, and the errors of the magnetic induction intensity collected by different magnetic detection probes are reduced. The magnetic induction intensity collected by the magnetic detection probes is obtained by a magnetic processing unit, and a magnetic induction intensity difference value between the magnetic induction intensity and the reference magnetic induction intensity is calculated; and when at least one magnetic induction intensity difference value does not meet a preset magnetic induction intensity difference value range, it is determined that the magneticfield distribution of the magnetic isolation plates is uneven, and the accuracy of the result indicating whether the magnetic field distribution of the magnetic isolation plates is even can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a detection fixture and a detection method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) display has the advantages of low energy consumption, self-illumination, wide viewing angle and fast response speed. At present, the method of preparing the film layer in the pixel unit of the OLED display by evaporation is relatively extensive. When the evaporation method is used to form a film, the mask plate is generally adsorbed on the substrate to be evaporated by the magnetic separator in the evaporation device, so as to fix the evaporation mask plate. [0003] However, the magnetic field of the magnetic spacer may be non-uniform, which will lead to a poor effect of the mask, thereby affecting the performance of the prepared film layer, and further affecting the overall performance of the OLED display. At present, the detection jig used to detect the unif...

[0003] However, the magnetic field of the magnetic spacer may be uneven, which will lead to poor mask effect, thereby affecting the performance of the prepared film layer, and then affecting the overall performance of the OLED display

At present, the detection jig used to detect the uniformity of the magnetic field of the magnetic partition can only read one piece of data at a time, and there is no uniform height during detection, resulting in large detection errors
