Problems solved by technology
[0003] However, the blades of the existing fans do not have good detection tools after the processing is completed, especially the radian of the blades, which is difficult to measure, and it is very difficult to detect the quality and installation consistency of the blades
Existing fan manufacturers generally only use visual inspection to inspect the fan blades, and in the process of fan blade processing and assembly, the blades will inevitably bump, resulting in a certain deformation of the final assembled fan blades. The deformation of the blades will lead to increased fan noise, reduced energy conversion rate, and poor balance.

The invention discloses a fan blade detection device, which comprises a bottom mold and a lifting mold. The bottom mold is provided with positioning grooves for positioning the blades. The bottom of the lifting mold is provided with a plurality of liftable push rods, and the upper ends of the several push rods are provided with elastic pieces. Each ejector rod is provided with a light hole, and the ejector rods on both sides are respectively provided with an infrared transmitter and an infrared receiver. The infrared receiver is connected to the single-chip microcomputer of the control circuit board, and the control circuit board is connected to the power supply and indication Light, the single-chip microcomputer is connected to the electric signal of the infrared receiver to control the indicator light to light up. When the lifting mold is pressed down to the fan blade of qualified shape, the infrared rays sent by the infrared transmitter pass through several light holes to the infrared receiver. The fan blade detection device can quickly and accurately detect whether the fan blades meet the requirements, effectively prevent defective fan blades from leaving the factory, and improve product quality.
Description
technical field [0001] The invention belongs to the technical field of fan processing and testing equipment, in particular to a fan blade testing device. Background technique [0002] A fan is a commonly used ventilation device. It is mainly used for air circulation and smoke exhaust. In the production process of fans, different fans have different blade parameters, which have high requirements for the radian parameters and installation angle of the blades in the fan blades. [0003] However, the blades of the existing fans do not have good inspection tools after the processing is completed, especially the radian of the blades, which is difficult to measure, and it is very difficult to inspect the quality and installation consistency of the blades. Existing fan manufacturers generally only use visual inspection to inspect the blades, but in the process of blade processing and assembly, the blades will inevitably bump, resulting in a certain deformation of the final assemble...
