[0004] However, the above-mentioned patent has single shooting angle, and the inclined side of the part cannot be clearly shot. In resistance screening, it is necessary to detect whether the resistance cap is damaged and whether the color ring on it is missing. Therefore, the machine is not suitable for detecting resistance. SUMMARY
[0005] The utility model solves the technical problem in view of the above prior art, and provides an automatic resistance visual screening machine with high automation degree, multi-angle and multi-directional detection of resistance, high detection precision and light supplementing function.
[0006] In order to achieve the above object, the following technical scheme is adopted, a resistance multi-directional visual screening machine, comprising a machine table and a vibrating disc, the machine table is provided with a rotating disc, the vibrating disc arranges resistors to the rotating disc, the rotating disc is provided with an infrared sensor, at least two groups of optical detectors with different shooting angles, a plurality of screening boxes and a material blocking plate in sequence along the rotating direction, the optical detector comprises an adjusting support and two groups of opposite cameras arranged on the adjusting support, the adjusting support is provided with an angle adjusting groove, one end of the camera is rotatably arranged on the adjusting support, and the other end is rotatably arranged at any angle of the angle adjusting groove through the adjusting member with adjustable tightness, at least two high-speed airflow blow pipes for blowing the resistance into the screening box are arranged at the opening of the screening box, and the material blocking plate blocks the missed detected resistance into the screening box.
[0007] The rotating disc is driven to rotate by the motor, and the resistors are arranged on the rotating disc by the vibrating disc. Since the infrared sensor, the optical detector and the screening box and the material blocking plate are sequentially arranged along the rotating direction of the rotating disc, the resistors are first placed under the infrared sensor to detect whether there is a resistor, then pass through the first group of optical detectors, first shoot the resistor from this angle for detection, then enter the shooting range of the second group of optical detectors with the rotation of the rotating disc, and realize multi-angle shooting of the resistor by shooting from different angles to observe whether there is damage or broken ring at each direction of the resistor. Compared with a single camera, the shooting angle is more diversified, the defects of the resistor at different positions can be found, and the defective rate is further reduced. Each group of optical detectors realizes simultaneous shooting of both sides of the resistor through the opposite cameras, which is more comprehensive than single camera shooting. The high-speed airflow blow pipes are controlled respectively. When the optical detector detects a qualified product, one of the high-speed airflow blow pipes blows and blows the qualified resistor into one of the screening boxes for storing qualified products. Similarly, when the optical detector detects a defective product, the other high-speed airflow blow pipe blows and blows the defective resistor into the other screening box for storing defective products, thereby realizing visual screening of the resistor. However, the high-speed airflow blow pipe may also have a case where part of the resistor is not blown into the screening box, so the material blocking plate is needed to block the resistor not blown into the screening box by the high-speed airflow blow pipe into the screening box, thereby preventing mixing with the resistors to be detected arranged in the vibrating disc and causing inaccurate detection.
