Surface focusing position detecting mechanism

Abstract

The invention discloses a surface focusing position detecting mechanism which comprises a channel bottom plate. A first homocentric squares-shaped plate is arranged on the channel bottom plate. A light source assembly is arranged on the surface of the first homocentric squares-shaped plate. A second homocentric squares-shaped plate is arranged on the first homocentric squares-shaped plate and provided with a beam frame. One end of the beam frame is connected with a first electric slide table moving in the X-axis direction, and the other end of the beam frame is connected with an auxiliary slide rail. Two first cameras moving in the Z-axis direction are perpendicularly arranged on the beam frame. Slide assemblies moving in the Y-axis direction are arranged between the first cameras and the beam frame. A three-axis mechanical hand is arranged between the first homocentric squares-shaped plate and the second homocentric squares-shaped plate, provided with a second camera and arranged between two portal frames. The portal frames are arranged on the channel bottom plate and provided with code scanning guns. The surface focusing position detecting mechanism is reasonable in design, compact in structure, good in detecting effect and high in universality.

Description

technical field [0001] The invention relates to the field of detection mechanisms, in particular to a surface focus position detection mechanism. Background technique [0002] Many precision electronic circuit board components are usually placed in the carrier for transmission assembly. After the components are mounted on the surface, it is necessary to check the installation position of the components to check whether the position is within the set range, so as to facilitate the overall circuit board assembly. Layout, since the circuit board is placed in the carrier, for the stability of transportation, the carrier will adopt clamping and other stops to stabilize, so it will block the corners of the circuit board and cause some trouble to find the center point, so only The inner edge can be used as the basis to locate the center point, and then it can be calculated whether it is qualified by multiple coordinate distances between the position of the component to be inspected...
