Abstract

The invention discloses high speed visual detection and recognition equipment. The high speed visual detection and recognition equipment comprises a main body support, a bearing platform, a first moving mechanism, a first shooting device and a control device, wherein the bearing platform is arranged in the main body support and used for placing and conveying to-be-detected and recognized finishedcircular boards; the first moving mechanism is arranged at the top of the main body support and can move in the Y-axis direction; the first shooting device is arranged on the first moving mechanism and used for shooting the finished circuit boards; the control device is arranged in the main body support, is connected with the first moving mechanism and the first shooting device and is used for controlling. The high speed visual detection and recognition equipment disclosed by the invention has the advantages of low quantity of required shooting devices, high degree of automation and high shooting efficiency.

Description

technical field [0001] The invention relates to the technical field of visual detection and recognition, in particular to a high-speed visual detection and recognition device. Background technique [0002] Finished circuit board (Printed Circuit Board + Assembly, referred to as PCBA), that is, the finished circuit board is PCBA, PCBA is one of the key components of electronic equipment. The product does not require this step) to obtain a circuit board, that is, various electronic devices are assembled on the PCB through the surface packaging process. The position of the components on the PCBA, the short circuit of the solder joints and the number of pin headers directly affect the performance and yield of the circuit board. Therefore, PCBA has become an indispensable and very important link to check whether the product is qualified before delivery. [0003] At present, the existing PCBA defect detection and recognition mainly adopts the logical type of automatic optical in...
