When the longitudinal adjustment is performed, because the mitre bar 55 contacts the total longitudinal contact 57, when the transverse adjustment mechanism 5 is completed, the longitudinal adjustment mechanism 6 is in circuit communication, which facilitates the longitudinal adjustment, and because the central support bar 34 contacts the display screen 4 first and because of the curved screen, the pressure applied to the central support bar 34 is the largest, the pressure applied to the piezoresistors 36 of the two side auxiliary support bars 32 and the side support bars 33 is smaller than the pressure applied to the piezoresistor 36 of the central support bar 34, as shown in fig. 6, the pressure applied to the piezoresistor 36 of the central support bar 34 is greater than the pressure applied to the side support bar 33 and the piezoresistor 36 of the auxiliary support bar 32, so that the electromagnetic forces of the side induction electromagnet 61 and the central induction electromagnet 62 generate deviation, thereby the longitudinal adjustment movable bar 63 contacts the longitudinal adjustment contact 65, and the piezoresistors 36 inside the side support bar 33 and the auxiliary support bar 32 are smaller than the pressure applied to the central support bar 34, the hydraulic pump 31 moves the corresponding auxiliary support bar 32 and the side support bar 33 upward.
Therefore, the pressure balance of the piezoresistors 36 in each support rod is achieved, and the auxiliary support rod 32, the side support rod 33 and the central support rod 34 are adapted to the radian of the display screen 4 at the moment. The effect of automatically adapting to the radian of the curved surface is achieved. Effectively guarantee the application scope of the device, increase the result of use of the device.
During detection, the lifting rod 8 controls the top pressing ring 11 to move downwards, so that the top pressing ring 11 is adaptive to the display screen 4 to be pressed, the display screen 4 is conveniently fixed, and meanwhile, the sliding rail 9 is used for controlling the optical measurement mechanism 10 to perform optical detection.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
