[0029] To solve the problem that the detection equipment for AMI detection of display modules in the prior art cannot improve efficiency, as shown in Figures 1-5 This application discloses a display module AMI detection device, including a product fixture 10, a fixture conveyor line 20, and two AMI detection mechanisms 30;

[0030] The product fixture is used for obliquely loading two display modules and is arranged on the fixture conveyor line to be conveyed and moved by the fixture conveyor line;

[0031] Two AMI detection mechanisms are respectively arranged on the opposite sides of the jig conveyor line. The AMI detection mechanism includes a detection machine table 31 with an inclined tabletop, a longitudinal automatic adjustment component 32 arranged on the tabletop of the detection machine table, a transverse bracket 33 connected to the longitudinal automatic adjustment component, two transverse adjustment components 34 respectively arranged on the opposite sides of the transverse bracket, an angle adjustment component 35 respectively connected to the two transverse adjustment components, and a camera detection component 36 installed on the angle adjustment component.

[0032] Based on the above structure, the working principle of this application will be briefly described as follows:

[0033] In the first step, the operator first adjusts the detection angle of the camera detection component through the angle adjustment component, then adjusts the horizontal position of the angle adjustment component through the horizontal adjustment component, and then adjusts the position of the transverse bracket through the longitudinal drive component;

[0034] In the second step, the operator loads two display modules onto the product jig and conveys it through the jig assembly line to the space between the two AMI detection mechanisms. After reaching the set position, the camera detection components of the two AMI detection mechanisms detect it.

[0035] And when the product jig enters the space between the two AMI detection mechanisms, the operator needs to respectively wire and power on the two display modules loaded on the product jig.

[0036] In addition to the above, this application further includes an outer frame 40. Relative to the lower part of the middle of the outer frame, there are two vertical brackets 50.

[0037] In order to further increase the brightness near the display module and thus improve the detection quality of the camera detection component, in this application, on the opposite sides of the middle part of the jig conveyor line, there are respectively rectangular frames 80 inclined towards the jig conveyor line. The two rectangular frames are connected to the outer frame through a connecting plate 90.
