At present, the development of the manufacturing industry is more and more important in various countries, and various countries accelerate promotion of technical innovation, promote transformation and upgrade of the manufacturing industry, and thus, the intelligent manufacturing strategy is continuously increased. The intelligent detection belongs to a branch of intelligent manufacturing, and manufacturing enterprises develop automatic intelligent devices suitable for processing failure detection used in respective industries to replace traditional manual detection modes. For example, the welding strength of a circuit board is generally observed by naked eyes in the traditional manufacturing industry, at present, part of enterprises detect the inside of a welding part in a mode of automatic identification of a gray scale image machine which is easier to observe by penetrating X rays through the circuit board, and the welding surface is detected by AOI contrast.

Firstly, the welding spots with the problem images are observed and knocked in a visual observation mode. Then, a live test is performed to find a solder joint that generates heat, and then whether the connection is a virtual connection is tested. Although some parts are successfully welded on the surface of part welding points, the welding surface is small, and the parts can be separated after a certain impact is applied, so that the welding is called as cold welding or cold connection. The work efficiency of visual inspection of welding spots is low, operators are required to have abundant operation experience, otherwise missing images are easy to appear, and the welding spots are already being eliminated. Irradiating the circuit board under X-ray to image, and finding out the false soldering hollow point. The method seems to be effective, but the imaging time of the test is long, each welding point needs to be observed, the time consumption is long, the production efficiency is not greatly improved, and in addition, the ray pollution exists. The problem of the largest AOI contrast is that the precision is low, the number of false alarms is large, and the internal weld strength cannot be detected. There is therefore a need for improved current circuit board weld strength failure detection approaches.

In addition, the failed parts are easy to drop in the equipment, have irremovable influence on the processing and detection of other materials, and need to be removed from the detection device in time.

A device in which a pulsating voltage obtained by half-wave rectifying an alternating current is applied to a coil and a movable core is vibrated by an electromagnetic force is called an electromagnetic vibrator. The vibration intensity can be adjusted by a controller. The parts after welding are vibrated by the electromagnetic vibrator, the failure parts are removed or damaged in advance, but the welding strength of the normal parts is not influenced, so that the method becomes a new research direction for intelligently detecting the welding failure mode of the circuit board.

The invention provides a failure detection electromagnetic vibration test system and a control method thereof, wherein the failure parts and materials are separated and removed by utilizing electromagnetic vibration, and the control system can automatically check and replace risk equipment according to failure positions, so that the material failure detection efficiency is improved, and the failure parts are prevented from influencing further processing of the materials.
