The invention discloses a computer fan blade flatness detection device and a flatness detection method thereof. The computer fan blade flatness detection device includes: fan clamping and driving mechanisms each of which includes a fan support assembly used for supporting a fan and a blade rotating assembly used for rotating a fan blade; a one-dimensional code recognition device used for collecting one-dimensional code information of the fan supported on the fan support assembly; a distance measuring device used for collecting at least two sets of height distance information of a fixed point of a fan shell supported on the fan support assembly and height distance information of a measuring fixed point on the fan blade in a rotation process; and an upper computer which is in communication connection with the one-dimensional code recognition device and the distance measuring device. The computer fan blade flatness detection device provided by the invention can perform one-dimensional code scanning and measurement of the flatness of the computer fan blade at the same time, thereby improving detection efficiency.
Description
technical field [0001] The invention relates to a computer fan blade flatness detection device and a flatness detection method thereof. Background technique [0002] At present, the flatness detection of computer fan blades is a process that must be inspected for quality control after fan assembly. It directly affects the operation reliability of the fan and the traceability of the quality of the production process. Due to the deformation of the fan blade due to factors such as manufacturing and installation, it is required to detect the flatness of the fan during the rotation process, and the accuracy requires 0.01mm. However, in the existing detection devices, it is necessary to manually scan the one-dimensional code first, and then manually measure. The speed of the detection and recording equipment is low, and it is a semi-automatic detection equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the de...
