Description

Screen brightness uniformity detection jig Technical Field The utility model relates to the technical field of screen detection, in particular to a screen brightness uniformity detection jig. Background In modern electronic devices, screen brightness is one of the key factors affecting display quality and user experience. Proper screen brightness ensures that the user can see the content on the screen clearly under different ambient light conditions, whether in bright outdoor sunlight or in dim indoor environments. At present, along with development of technology in the prior art, the shapes of screens are more and more diversified, besides a common rectangular screen, a curved screen, a special-shaped screen and the like, a fixed screen detection jig cannot be adjusted according to the shapes of the screens, and therefore, a screen brightness uniformity detection jig is provided. Disclosure of utility model The main objective of the present utility model is to provide a screen brightness uniformity detection fixture, which can solve the problems set forth in the above background art. In order to achieve the above object, the utility model provides a screen brightness uniformity detection jig, which comprises a base, wherein the base is slidably connected with a lifting rod, the lifting rod is fixedly connected with an operation table, one side of the base is provided with a detection assembly, the detection assembly is provided with a tester, the base is fixedly connected with a workbench, a clamping limiting assembly is arranged on the workbench, a cleaning dust removing device is arranged on the clamping limiting assembly, and the clamping limiting assembly comprises: The motor is fixedly connected with the outer wall of the workbench, and the output end of the motor is fixedly connected with the bevel gear I; The bevel gear II is in meshed connection with the bevel gear II, penetrates through the operating platform, and is fixedly connected with the bidirectional screw rod. Preferably, the two-way screw thread connection has the grip block, the one end sliding connection that the grip block kept away from the two-way screw is in the spout of seting up on the operation panel surface, and two sets of grip blocks motion on the two-way screw, and the spout is supplementary steady slip in the slip process prevents the off normal, and when two sets of grip blocks moved in opposite directions, they can be close to gradually and contact the screen, finally press from both sides the screen clamp fastening on the operation panel. Preferably, the cleaning and dust removing device comprises a supporting seat, and the outer wall of the workbench is fixedly connected with the supporting seat. Preferably, the connecting rod of the bevel gear II is in transmission connection with the rotating rod through a transmission belt, the rotating rod is rotationally connected to the supporting seat, and the motion is transmitted to the rotating rod through the rotation of the bevel gear II. Preferably, the dwang and clearance cylinder fixed connection, clearance cylinder sets up in the top of operation panel, and the dwang drives the upset of clearance cylinder, conveys the screen that will detect the end to next step flow through the clearance of clearance cylinder. Preferably, the one end that the dwang was kept away from to the clearance cylinder rotates to be connected in the backup pad, and the steady rotation of clearance cylinder receives the support of backup pad to guaranteed the stationarity to screen clearance and conveying. The utility model provides a screen brightness uniformity detection jig. The beneficial effects are as follows: (1) This screen luminance homogeneity detects tool passes through the centre gripping spacing subassembly that sets up, work through the motor drives the output and then influences bevel gear one's rotation activity, bevel gear one and bevel gear two meshing are connected, realize the uniform velocity rotation of two sets of grip blocks on the two-way lead screw, the motion of sliding in-process spout is supplementary steady slip, prevent the off normal, when two sets of grip blocks move in opposite directions, they can be close to gradually and contact the screen, finally press from both sides the screen tightly to be fixed on the operation panel, the screw thread precision of two-way lead screw can ensure the positioning accuracy of grip block in the removal in-process, make the screen can be fixed in the preset position of operation panel accurately, can carry out accurate screen location, ensure the reliability and the uniformity of testing result. (2) This screen luminance homogeneity detects tool passes through the clearance dust collector who sets up, transmits the motion to the dwang through bevel gear two's rotation on, and the dwang drives the upset of clearance cylinder, conveys the screen that will detect the end to next step flow through the clearance of clearance cylinder,
