Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of visual detection, and particularly relates to a micro transformer detection production line and a detection method. BACKGROUND

[0002] A micro transformer is a kind of transformer with small size, which is usually used in low-voltage environment. It is widely used in various electronic devices, such as handheld devices, power adapters of notebook computers and various portable electronic devices. The design goal of the micro transformer is to reduce the volume and weight while maintaining high efficiency and reliability. As shown in the accompanying drawings, the width of the commonly used micro transformer is between 20-96mm. The micro transformer needs to be detected in multiple aspects during the production process, and appearance detection is an important item. The micro transformer has the following problems during appearance detection. Figure 11

[0003] 1. During appearance detection of the micro transformer, industrial visual detection technology is usually used to take a photo of the micro transformer by a CCD camera. The photo is compared with the photo of the qualified product in the database to detect whether the transformer is qualified. However, different models of transformers have different sizes, and the factory may produce different models of micro transformers in the same batch according to customer demand. The situation of detecting different models of micro transformers at the same time may be faced. However, the existing detection equipment needs to adjust the corresponding fixtures, the number and position of the CCD camera and the corresponding supporting equipment when detecting different models of micro transformers. It is difficult to detect different models of micro transformers at the same time, and even different detection equipment needs to be replaced for detection, which is high in cost and low in efficiency.

[0004] 2. Whether the micro transformer is directly shipped after production or stored for shipment, it needs to be detected before shipment. During production and storage, debris and impurities will be generated on the micro transformer, which will affect the detection result. Therefore, the dust removal step is necessary. The existing detection equipment generally does not have dust removal function, and detection is carried out after a separate dust removal step, which increases the detection time and is low in efficiency. The dust removal step needs to be separately provided with a driving source, which increases the equipment use cost. During dust removal, the micro transformer usually remains stationary and is directly blown to remove dust. The gas is difficult to blow to each surface of the micro transformer, and the dust removal effect is poor.

[0005] ​3. In the micro transformer appearance detection, a CCD camera is usually used to take a single angle of the micro transformer, which can only detect whether the micro transformer at a single angle has defects, has a large detection error and reduces the detection accuracy, since the cracks, oil leakage traces or rust of the transformer shell may be distributed on different sides of the transformer, and the obvious degree of these defects observed at different angles is different, and even cannot be directly observed at some specific angles, so it is necessary to observe the transformer at multiple angles.

At this time, the moving mechanism 6 drives the multi-point self-adaptive clamping mechanism 7 and the clamped micro transformer thereon to move downwards, which shortens the distance between the micro transformer and the CCD industrial camera 15, ensures the quality of the photo shooting, and simultaneously drives the fixed arm 18 and the No. 1 U-shaped frame 17 thereon to move downwards, synchronously drives the roller 16 to move downwards, until the roller 16 moves into the groove at the top of the limiting slide rail 13. At this time, the No. 2 driving gear 741 does not contact the No. 1 gear rack 8, and the limiting clamping of the roller 16 and the limiting slide rail 13 ensures the accuracy of the movement of the micro transformer from right to left. At this time, as the moving mechanism 6 drives the multi-point self-adaptive clamping mechanism 7 and the clamped micro transformer thereon to move from right to left, when the No. 2 driving gear 741 contacts and engages with the No. 1 gear rack 8, as it moves from right to left, it drives the No. 2 driving gear 741 and the mounting shaft 742 thereon to start rotating, simultaneously drives the rotating plate 748 and the clamping plate 746 to rotate, and then synchronously drives the micro transformer to rotate, realizing the rotation of the micro transformer while moving from right to left. During the rotation, the CCD industrial camera 15 with a pre-set distance shoots each face of the micro transformer, and the shooting pictures are transmitted to the background processor for feature recognition and analysis comparison, and the analysis results are directly displayed on the display 11, realizing the detection and rotation of the transformer at the same time. Through the comprehensive judgment of multiple photos shot by the CCD industrial camera 15, it is determined whether there is oil leakage, rust or crack outside the transformer. At the same time, through the rotation during detection, the heat dissipation silicone grease inside the transformer can be easily leaked out of the gap through the action of centrifugal force, which is more convenient to reflect the obviousness of the crack. At the same time, through the rotation during detection, the working state of some special transformers can be simulated to ensure that there is no scratching or magnetic circuit abnormality under the working state. The distance of the CCD industrial camera 15 can be adjusted according to the size of the micro transformer and the moving speed of the moving mechanism 6. When the No. 2 driving gear 741 rotates, it synchronously drives the No. 1 driven gear 21 to rotate rapidly, simultaneously drives the No. 2 driven gear 27 and the No. 2 connecting shaft 29 thereon to rotate rapidly, and synchronously drives the suction blade 24 to rotate and suck, so that the external air is sucked into the suction box 22, then transported to the air jet pipe 26 through the suction pipe 25 and sprayed out, and the sprayed air is used to blow and clean the surface of the micro transformer. Since the micro transformer itself rotates, the cleaning effect is improved, and the micro transformer itself rotates to realize dust removal, further improving the cleaning efficiency.

[0059] S3, rotating shooting: when the different types of micro transformers are synchronously clamped and stabilized, the mobile mechanism 6 is used to move the clamped micro transformer into the base 1, until the roller 16 is clamped into the limiting slide rail 13, and then the mobile mechanism 6 drives the different types of micro transformers to move from right to left, until the second driving gear 741 on the multi-point adaptive clamping mechanism 7 is engaged with the first gear rack 8, and then the micro transformer is rotated with the movement;

[0060] S4, automatic dust removal: the mobile mechanism 6 drives the different types of micro transformers to move from right to left, and the multi-point adaptive clamping mechanism 7 drives the blowing dust removal mechanism 2 to rotate and blow air synchronously, so as to blow and clean different surfaces of the micro transformer;

If the error feature is recognized, it means that the micro transformer has defects in appearance, including whether there are cracks and depressions on the surface, whether the label and logo are missing, whether the pins are bent and lack welding, whether the accessories are installed in place, and whether the key dimensions are qualified. The detection result is directly displayed on the display 11.
