s101, when a product is conveyed to a feeding sensor, detecting whether the product is qualified or not by an online detection system to obtain a detection result.
The use scene of this scheme is whether detect the product on the product conveyer belt of production line and pass or not, carries out accurate rejection to unqualified product. Fig. 2 is a schematic diagram of online detection and rejection according to an embodiment of the present invention, and as shown in fig. 2, the online detection and rejection system includes a product 21 on a conveyor belt, a feeding sensor 22, an online detection system 23, a discharging sensor 24, and a rejection system 25. The installation position of each device is shown in fig. 2. In order to avoid accumulation of single products on the conveyor belt or inaccurate detection results, a certain distance should be kept between the feeding sensor 22 and the feeding sensor 24, the distance is determined according to the time of the products, and the longer the detection time, and conversely, the shorter the detection time. The method is beneficial to guaranteeing the product detection time and the accuracy of product detection.
In one embodiment, the feed sensor position may be used to determine the position at which the feed sensor is installed, which may be adjusted accordingly for different product types. The on-line detecting means may be means for detecting whether the product is acceptable. The feeding sensor and the online detection system can be arranged at the initial position of the conveyor belt, and the online detection system can be directly triggered to be started when the feeding sensor detects products. The test results may include pass and fail. In one embodiment, when the product is conveyed to a position which can be detected by the feeding sensor during the process of conveying the product by the product conveying belt, the detection condition of the online detection system is triggered, and the product passing through the position at the moment is detected by the online detection system. Specifically, whether the product meets the detection condition can be detected according to the corresponding algorithm, and if the product meets the detection condition, the product is determined to be unqualified, otherwise, the product is determined to be qualified. The detection conditions may be preset and may include the number in the product, appearance, date of manufacture, etc. By way of example, the online detection system detects whether the appearance of the product is defective, whether the product exceeds its shelf life, whether the product is missing, etc. When the appearance is damaged, the detected product is determined to be unqualified if the product exceeds the quality guarantee period and the quantity of the product is lost, and the detected product is determined to be qualified if the conditions are not met.

The pulse encoder is an optical position detecting element, and the encoding disk is directly mounted on the rotating shaft of the motor to detect the rotation angle position and speed change of the shaft, determine the rotation condition of the encoding disk, and output a pulse signal, which may be an electric pulse. When the discharging sensor detects the unqualified product, the encoding disk on the motor rotating shaft is triggered to rotate.

The displacement distance may be the distance of the product center point from the discharge inductor. Optionally, the pulse editor is arranged on the encoding disc.
In one embodiment, when the detection result is failed, the code plate on the rotating shaft of the motor is triggered to rotate and a pulse signal is output when the center point of the product is conveyed to the detection position of the discharge sensor.
