AI Technical Summary

Technical Problem

Existing automated testing equipment suffers from problems such as insufficient positioning accuracy, inaccurate correlation between product information and testing data, and susceptibility to bumps and damage during transportation when testing double-sided products. These issues make it difficult to meet the high efficiency, high precision, and high reliability requirements of the precision manufacturing field.

Method used

By combining the top and bottom visual inspection mechanisms with the adsorption and transfer function of the robotic arm, automated continuous inspection of the front and back of the product is achieved. Precise positioning is achieved through the lifting slide and camera adjustment knob, and four sets of side light-emitting plates provide appropriate lighting. The buffer module of the robotic arm prevents collisions, and the NG product placement mechanism isolates unqualified products through the partition placement frame and suction cup module.

Benefits of technology

It enables automated continuous inspection of both sides of the product, improving inspection efficiency, avoiding damage from bumps during transportation, increasing inspection accuracy, reducing misjudgments, ensuring inspection quality and efficiency, and adapting to mass production.

Abstract

The invention discloses a product front and back side detection device, and particularly relates to the technical field of keyboard product detection equipment, and the product front and back side detection device comprises a top appearance visual detection mechanism and a bottom appearance visual detection mechanism. Through cooperation of the top appearance visual detection mechanism and the bottom appearance visual detection mechanism and combination of the adsorption transfer function of the manipulator mechanism, automatic continuous detection of the front and back surfaces of a product is realized, manual overturning and repeated transfer are not needed, the detection efficiency is greatly improved, collision damage possibly occurring in the transfer process is avoided, and the product quality is improved. The main camera can be accurately positioned through a lifting sliding table, a camera front-back adjusting knob and a camera left-right adjusting knob, four sets of side light-emitting plates can adjust the height and angle to provide adaptive illumination, clear images are ensured, the detection precision is improved, misjudgment is reduced, a buffer module of the mechanical arm mechanism can buffer taking and placing impact, full-process automatic operation reduces manual intervention, and the working efficiency is improved. The method is suitable for batch production and effectively guarantees the detection quality and efficiency.
