Multi-linear array camera online single-face detection device

Abstract

The invention provides a multi-linear array camera online single-face detection device which comprises a detection rack and a following structure: a transmission assembly and a single-face detection optical system. The transmission assembly comprises an input mechanism, a detection zone transmission mechanism and an output mechanism which are connected in sequence; the input mechanism comprises a plurality of conveying idler wheels arranged in perpendicular to the running direction of to-be-detected pieces, two guide plates arranged on the conveying idler wheels and arranged in perpendicular to the conveying idler wheels, and a first driving mechanism for driving the two guide plates to synchronously move in an opposite direction or a contrary direction; the two guide plates are respectively provided with accommodating grooves for accommodating the conveying idler wheels; the detection zone transmission mechanism comprises a conveying belt and a plurality of pressing idler wheels arranged above the conveying belt and used for auxiliary pressing of the to-be-detected pieces; the single-face detection optical system comprises a camera assembly and a light source assembly. The quality of images collected from the to-be-detected pieces is improved.

Description

technical field [0001] The invention relates to the technical field of on-line inspection of circuit boards, in particular to an on-line single-sided inspection device with multi-line array cameras. Background technique [0002] Traditional circuit board inspection equipment installs the optical imaging system on the beam (called the X-axis), so that the optical imaging system can move left and right on the beam, and the lighting system is fixed above the vacuum adsorption platform, which can also be connected to the X-axis , with the optical imaging system moving left and right, the circuit board is placed on the vacuum adsorption platform. The vacuum adsorption platform can move back and forth, so that the circuit board can pass smoothly under the field of view of the optical imaging system. Through the left and right movement of the optical imaging system and the forward and backward movement of the vacuum adsorption platform, the optical imaging system collects all the ...

AI Technical Summary

Problems solved by technology

Its outstanding disadvantages are: the existing circuit board inspection equipment manually places the circuit board on the vacuum adsorption platform, and then moves the circuit board to the image acquisition area of ​​the optical imaging system by controlling the movement of the vacuum adsorption platform. The operation process is complicated. And the efficiency is low; it cannot be used in connection with the circuit board production line
