Magnetic material industry - NdFeB workpiece size appearance detection equipment

With the continuous growth of market demand, the application of NdFeB permanent magnet products has become more and more extensive, and the output has been rising year by year. However, the headaches for major manufacturers are that the backward quality inspection methods and extremely low detection efficiency are associated with spurt-type The production of huge contradictions has become one of the bottlenecks that limit its development. The use of automated rapid testing equipment to replace the manual sampling method in the past can provide customers with a comprehensive increase in the rate of qualified products and enhance their market competitiveness.

【Device Overview】
NdFeB workpiece size appearance detection equipment, using optical control technology, the use of non-contact optical measurement methods, can quickly detect the size of various permanent magnet products, data defects and appearance, and automatic sorting. The entire equipment has no wearing parts and the maintenance cost is very low.

【Fundamental】
The system consists of industrial computer, digital acquisition card, motion controller, test unit, material transfer unit and sorting unit. The proximity sensor is responsible for triggering the detection sensor; the digital acquisition card transmits the digital signal collected by the test unit to the industrial control computer, and the industrial control computer performs data processing; the motion controller receives the control signal transmitted by the industrial control computer, and the material conveying unit and the sorting unit Control; material transfer unit will automatically discharge the material in the material box, and then transmitted to the test station; after the completion of the test, the sorting unit will automatically sort the products according to the user-set quality standards, and classified output.

[Specifications]
(1) Detection efficiency: 200~400 pieces/min (depending on the size and shape of the workpiece);
(2) Test items: It can detect various size data of various specifications and appearance defects on both sides;
(3) Shapes of products that can be detected: square rings (including outer racetrack rings), square pieces (including inner racetrack rings), rings, wafers, VCM magnetic pieces, etc.;
(4) Product size detection range: 2mm~25mm, thickness no more than 3mm;
(5) Automatic discharge and cutting;
(6) Automatic sorting: automatic sorting according to the user-defined eligibility criteria, and classification output;
(7) It can automatically store product inspection data and statistics data such as qualification rate of each batch of products, and can automatically generate reports to facilitate quality tracking and control;

[equipment value comparison]

(1) Improve product quality: For the detection of the finished product size, the user can only adopt the sampling inspection method at the moment, causing the products to be returned in batches. After adopting this scheme, the size will be fully inspected, and the rate of unqualified products will be greatly reduced when the product is delivered. For appearance detection, the user currently uses manual methods for detection, which is easily affected by human eye fatigue and other factors. The test result is not objective. After this solution is adopted, computer vision technology can be used to objectively judge appearance defects, thereby improving the quality of delivered products. .

(2) Enhancing market position: Currently, in the NdFeB permanent magnet products industry, inspections are basically performed manually. The highly efficient and automated testing equipment provided by this program improves the quality of product delivery and also enhances the user's overall Market status creates conditions for users to get more orders.
