Double-channel rotary table assembly

Abstract

The invention discloses a double-channel rotary table assembly. The double-channel rotary table assembly comprises a barrel-shaped mounting seat, wherein a central shaft, which can rotate along the radial direction, is mounted in the barrel-shaped mounting seat; a rotary table module is fixedly arranged at the outer side of the upper part of the central shaft; the rotary table module comprises a rotary table; a rotary table lower stopping disc is arranged at the lower part of a rotary table plate; a vacuum friction sheet is arranged at the outer side of the upper part of the rotary table; a rotary table pressing plate is fixedly arranged at the inner side of the upper part of the rotary table; a vacuum ventilation block is arranged at the upper part of the vacuum friction sheet; a first vacuum connector is arranged at the upper part of the central shaft; a second vacuum connector is mounted at the upper part of the vacuum ventilation block; a first vacuum channel and a second vacuum channel are formed in the rotary table; the first vacuum channel is communicated with the first vacuum connector; the second vacuum channel is communicated with the second vacuum connector. The double-channel rotary table assembly disclosed by the invention has the advantages of stable performance, high reliability, high working efficiency and the like which do not belong to the prior art.

Description

technical field [0001] The invention relates to the field of LED detection, in particular to a dual-channel turntable assembly. Background technique [0002] In the field of LED testing, the turntable for testing is a core testing component. Existing detection turntables generally perform detection work through a single channel during application. In the specific application process, technical defects such as unstable performance, low detection efficiency, mutual interference, and high detection error rate are prone to occur. These defects seriously limit the This field is further developed and applied. [0003] In view of this, the purpose of the present invention is to provide a new technical solution to solve the existing technical defects. Contents of the invention [0004] In order to overcome the shortcomings of the prior art, the present invention provides a dual-channel turntable assembly, which solves the technical defects of the prior art such as unstable perfo...
