at least two parallel arranged conveying rails 21;

the manipulator 22 is used for grabbing the display panel, is arranged on the conveying track 21, can move along the conveying track 21 and can lift;

When the GAMMA detection stations 23 are arranged in groups, the GAMMA detection stations 231 in each group are arranged vertically along the conveying rails 21, the space utilization efficiency is improved to the maximum extent by vertically arranging the GAMMA detection stations 231 (as shown in fig. 8a, 2 GAMMA detection stations 231 arranged in a high-low arrangement), at the same time, the GAMMA detection stations 231 can move on the conveying rails 21 to reach under the manipulators 22 on any one conveying rail 21 or leave under the manipulators 22, when the GAMMA detection stations 231 need to be placed in a display panel, the GAMMA detection stations 231 move to be under the manipulators 22, the manipulators 22 place the display panel to be detected on the GAMMA detection stations 231, then the GAMMA detection stations 231 with the display panel placed thereon leave under the manipulators 22 along the conveying rails 21, at this time, another GAMMA detection station 231 in the same group can reach under the manipulators 22, to receive the display panel, after the GAMMA detection is completed, the GAMMA detection station 231 with the display panel placed thereon reaches the position right below the manipulator 22 along the conveying rail 21, and waits for the manipulator 22 to take away the display panel on the GAMMA detection station 231.
