Abstract

This utility model discloses an LED cabinet splicing accuracy calibration device, relating to the field of LED cabinet splicing technology. It includes a calibration platform, an LED cabinet positioning mechanism, a first distance sensor, a second distance sensor, and a third distance sensor. The LED cabinet positioning mechanism includes a first positioning component and a second positioning component. The first positioning component is disposed on the top of the calibration platform, and the second positioning component is disposed on a first side plate. A moving beam is provided above the first and second side plates. A first distance sensor is disposed at the bottom of a first slide block. A second distance sensor is disposed on the first positioning component, and a third distance sensor is disposed on the second positioning component. The first distance sensor of this utility model can comprehensively calibrate the flatness error after LED cabinet splicing, while the second and third distance sensors disposed on the first positioning component can be used to calibrate the splicing regularity error after LED cabinet splicing.
