An engine cylinder head screw missing detection device and detection method

Abstract

The invention discloses an apparatus and method for detecting less installed screws on an engine cylinder cover. The apparatus comprises a control cabinet and a top work platform, wherein a main computer and light six-shaft robot are arranged above the work bench, and the end part of the light six-shaft robot is provided with a shooting unit and a platform precision detection unit. The other side of the work bench is provided with the engine cylinder cover with installed screws. The control cabinet controls the shooting unit to shoot the images of the engine cylinder cover and send the images to the main computer for image matching, the main computer searches and records the position of points to be tested, plans a detection path, and sends a starting signal to the light six-shaft robot, and the light six-shaft robot drives the shooting unit to move according to the pre-planned detection path to detect whether less screws are installed on the engine cylinder cover. The apparatus has the advantages of high flexibility and universality, low cost and comprehensive detection, effectively prevents the defects of mixed flow of heterotype products in the prior art.

Description

technical field [0001] The invention relates to a detection technology for engine cylinder head screw leakage, in particular to an engine cylinder head screw leakage detection device. Background technique [0002] In the industrial assembly line, the pose of the parts is not fixed. There is always some deviation between the pose of the actual target object and the pose of the ideal target object, and it is this deviation that often causes the robot to fail to perform tasks, and there are some parts. It needs to be detected through multiple faces and multiple angles, and this kind of detection often needs to be detected by installing multiple vision sensors, which leads to increased cost requirements. The cost of the detection system is proportional to the number of points to be detected, and the versatility is poor, which makes the robot The practical application range is greatly limited, and it is not flexible enough to be suitable for mixed-flow production lines with a lar...

[0002] In industrial assembly line occasions, the pose of parts is not fixed, and there is always some deviation between the pose of the actual target object and the pose of the ideal target object, and it is this deviation that often causes the robot to fail to perform tasks, and some parts It needs to be detected by multi-faceted and multi-angle, and this kind of detection often needs to be detected by installing multiple visual sensors, resulting in increased cost requirements. The cost of the detection system is proportional to the number of points that need to be detected, and the versatility is poor. The actual application range is greatly limited, and it is not flexible enough to be suitable for mixed-flow production lines and small-batch production lines with a large number of special-shaped products.
