The invention also discloses a display screen detection device and a display screen detection method, and the display screen detection device and the display screen detection method comprise the following steps:
s1: when the defect detection is carried out on the display screen, the display screen can be placed on the supporting plate on the inner side of the lower movable plate, and at the moment, the counterweight guide block on the upper movable plate can drive the power plate to move downwards under the action of self gravity, so that the fixed push ring can drive the connecting tooth movable rod to move through the connecting tooth movable rod, the connecting tooth movable rod can move along the single moving groove, the connecting tooth movable rod can rotate the supporting plate by shifting the connecting tooth movable wheel, one end of the supporting plate on the inner side of the upper movable plate is rotated to the position above the upper movable plate, and at the moment, the supporting plate on the inner side of the upper movable plate cannot shield the display screen;
s2: at the moment, the position of the display screen can be calibrated, and then the defect detection treatment can be carried out on one surface of the display screen on the lower movable plate through the detection probe;
s3: after one side of the display screen is detected, the rotating rod handle can be held, then the rotating rod handle is pulled towards the direction far away from the circle center of the pin connecting fixed ring, at the moment, the moving swing rod can move relative to the force adjusting sleeve block along with the movement of the rotating rod handle, one end of the pushing connecting spring is pulled by the moving swing rod to extend in the process, meanwhile, the rotating clamping pin is far away from the clamping hole along with the movement of the moving swing rod, when the rotating rod handle is far away from the circle center of the pin connecting fixed ring, the moving swing rod can be limited through the locking piece, at the moment, the pushing connecting spring can keep the extending state all the time, then, the rotating rod handle can be rotated, so that the rotating rod handle rotates along the circle center of the pin connecting fixed ring, the force arm generated by the rotating bidirectional spiral rod can be increased due to the fact that the circle center of the rotating rod handle is far away from the circle center of the bidirectional spiral rod, at the moment, the bidirectional spiral rod can be rotated by only needing small force, and the labor intensity of workers can be reduced;
s4: the bidirectional spiral moving rod rotates, so that the sleeve position block drives the lower moving plate and the upper moving plate to move towards the transverse central axis of the rotary connection frame, the pushing rod on the upper moving plate is limited by the lower moving plate, so that the counterweight guide block on the upper moving plate and the counterweight guide block on the lower moving plate are respectively far away from the upper moving plate and the lower moving plate, and the pushing rod on the upper moving plate can move relative to the upper moving plate in the process, so that the connecting gear moving wheel is driven to rotate reversely by the power plate, the fixed pushing ring, the pulling connecting block and the connecting gear moving rod, one end of the supporting plate is rotated to the inner side of the sleeve position rotating ring, and the display screen can be clamped, so that the stability of the display screen is improved;
s5: the fixed rod connecting block can be extruded by the extruding and pushing connecting rod in the process of relative movement of the two sleeve positioning blocks, so that the fixed rod connecting block moves towards the outer side of the rotary connecting frame, the I-shaped displacement frame can be pushed to move through the guiding and pushing column, the rotation blocking connecting pin can move towards the position far away from the circle center of the connecting and clamping disc under the moving action of the I-shaped displacement frame, and after the clamping and connecting assembly completely clamps the display screen through the relative movement of the sleeve positioning blocks, the rotation blocking connecting pin is just completely separated from the rotation blocking hole, and the connecting and clamping disc can lose the limit of the rotation blocking connecting pin, so that the eccentric rotating block is prevented from rotating when the display screen is not completely clamped, and the use safety of equipment is improved;
s6: at the moment, the eccentric rotating block can be rotated, the connecting and clamping connecting disc drives the spiral clamping rod to rotate through the rotation of the eccentric rotating block, the spiral clamping wheel can be driven to rotate when the spiral clamping rod rotates, so that the spiral clamping wheel drives the connecting and clamping connecting disc to rotate, the display screen is overturned, and meanwhile, the stability of the display screen during rotation is improved through the self-locking effect of the spiral clamping wheel and the spiral clamping rod;
s7: when the display screen is rotated by ninety degrees, the side face of the display screen can be subjected to defect detection through the detection probe, meanwhile, a worker can rotate the sleeve position rotating ring through the rotating ring handle, so that the sleeve position rotating ring drives the clamped display screen to rotate, and therefore, the defect detection can be performed on the periphery of the outer side of the display screen, the detection range is improved, the efficiency of the equipment for detecting the side face of the display screen is improved, and then the display screen can be rotated by ninety degrees again through the rotating assembly, so that the back face of the display screen can be upward;
s8: at the moment, the bidirectional spiral moving rod is reversely rotated through the clamping and connecting assembly so as to separate the upper moving plate from the lower moving plate, and the rotation-resisting connecting pin is inserted into the corresponding rotation-resisting hole on the outer side of the clamping and connecting disc again through the reverse movement of the sleeving position block, so that the stability of the eccentric rotating block is improved, the eccentric rotating block is prevented from rotating under the non-artificial action, and the stability of the display screen after being placed is improved;
s9: because the last movable plate at this moment is located the below of lower movable plate, the bracing board in the last movable plate does not take place to rotate under the effect of counter weight guide block this moment, so alright support the display screen through the bracing board in the last movable plate, and counter weight guide block on the lower movable plate pushes away the positioning rod and moves down under self effect this moment, so alright make the bracing board in the lower movable plate roll up to prevent that the bracing board on the lower movable plate from causing the back of display screen to shelter from, alright carry out defect detection through the detection probe to the back of display screen and handle afterwards, whole in-process display screen is in initial placement position always, with this detection efficiency that improves.
The detection probe of the present application can be judged by adopting a judgment mode of the detection probe or the light source such as disclosed in US20180246044A1 or chinese patent CN110160750a, and other accessory devices thereof are not detailed in the present application.
