Description

Carousel turning detection system

This creation is about an optical flip detection system, which more clearly states that this creation is a disc flip detection system that can perform flip and accurate alignment defect detection.

In the automatic testing equipment, the optical image shooting system is a part of the testing equipment that has a high cost ratio. In order to increase the efficiency of its testing capacity, the testing stage will try to carry a plurality of objects to be tested. By covering the entire object to be tested, the optical image is detected The system can detect at most a plurality of test objects at a time.

Generally, after the test object is produced by the previous process station, a plurality of test objects will be placed in a plastic tray. The plastic tray will be used as the smallest unit for transportation in the production line. When the plastic disc is transferred to the optical inspection station, the objects to be tested must be taken out of the plastic disc and placed on the inspection carrier of the optical inspection station one by one before scanning the objects to be tested for optical defects. At present, the plastic tray is transported, and the plurality of objects to be tested are taken out of the plastic tray transported in the production line by using a robotic arm. The front end of the robotic arm has a plurality of suction devices, which can suck a plurality of objects to be tested at one time The objects to be tested are placed on the inspection carrier of the optical inspection station, and it is repeated until they are full.

However, if the object to be measured is getting smaller and smaller, the suction nozzle of the robot arm is prone to suck up and cause a material drop, which will affect the overall yield of adsorption and handling. You can only find a smaller suction nozzle and a more precise fine-tuning device to ensure the handling of multiple analytes at a time, so that there is no material loss.

If the plastic disc is placed directly on the inspection carrier of the optical inspection station for measurement, it will be caused by the deformation, roughness and precision of the plastic disc being too poor, resulting in uneven positions or flatness of the object to be measured in the plastic disc One. If the optical inspection station directly measures the object to be measured in the plastic disc, it is easy to affect the shooting focal length due to the height or flatness of the object, or the light source is blocked by the limit post of the plastic disc, resulting in poor detection data. In addition, in response to the needs of the inspection project, the optical inspection station must detect the back of the object to be measured, and the robotic arm must also perform a flip operation before the object is placed on the inspection carrier. Therefore, if this creation can provide a flip-up detection system for turning and accurately aligning a plurality of objects to be tested at one time, the detection time efficiency will be improved and it will be industrially practical.
