AOI detection equipment

Abstract

The invention discloses AOI detection equipment which comprises a machine table, a mechanical arm arranged on the machine table, a visual detection module arranged on the mechanical arm and a control system arranged in the machine table. The visual detection module comprises a mounting bracket arranged at the front end of the mechanical arm, a 3D imaging module arranged on the mounting bracket, and a 2D area-array camera arranged beside the 3D imaging module. Through cooperative work of the mechanical arm and the visual detection system, the 2D area-array camera and the 3D imaging module are used for collecting product images, and the collected information is processed and analyzed, so that the quality problem of products can be detected more stably, the detection requirements of vertical direction and plane indexes of the products are met, the labor cost is effectively reduced, and the production efficiency and the production line quality control are improved.

Description

technical field [0001] The invention relates to the technical field of electronic product assembly testing equipment, in particular to an AOI testing equipment. Background technique [0002] In the production and assembly process of electronic products such as PCB boards or displays, it is necessary to carry out quality control on local details such as surface mount components, plug-in devices, soldering points, and locking screws on the product surface. In the traditional production and assembly process, for products with fewer control targets, manual quality inspection is mostly used to monitor the quality of the products. In the process of control, the work intensity of the operators is increased, and the operators are prone to failure due to fatigue. The rate is higher. For products with many control targets, AOI testing equipment is routinely used to complete the control of some plane indicators of the product. AOI (Automatic Optical Inspection) equipment is based on ...

AI Technical Summary

Problems solved by technology

However, it is difficult for AOI equipment to judge intuitively and accurately for indicators related to space, such as product height detection, whether the assembly is tilted, etc.

Therefore, the traditional detection method has very obvious limitations on the index detection in the vertical direction of the product, and cannot meet the updated and upgraded product quality control requirements.
