Next, turn on the ceiling fan to rotate the fan blade, the weight to be added to the fan blade and the fan blade thereof can be thereby determined accurately and swiftly from the position of laser beam spot on the calibration target, and it takes only one detection to complete, which is a rapid detection and saves a lot of time and labor.

Description

45 56 7 9 V. Description of the invention (1) The present invention relates to a "photoelectric detection method of ceiling fan deflection", especially it only needs to use reflective photoelectric crystals on the photodetector to receive the adhesive attached to the fan blade The light source of the upper reflector is used to drive the laser display lamp to emit laser light points and fall on the calibration target, that is, the fan blades and weights to be weighted can be accurately and quickly determined, and the detection result is not only highly accurate And, the detection action is very simple, fast, saves time and labor, can reduce costs, and has a high degree of economic and competitive benefits. <Background of the Invention> Most ceiling fans currently installed indoors are currently installed in the ceiling. After the center of gravity is detected by a counterweight, a counterweight is blindly selected first, and then the counterweight is installed in the On one of the fans of the ceiling fan, turn on the power of the ceiling fan, visually check whether the ceiling fan is skewed or shaken when rotating, and then turn off the power of the ceiling fan. After that, unplug the weight on the fan blade, and then again Or repeatedly installed on other fan blades in sequence, and judge the shaking of the ceiling fan one by one according to the same visual inspection method described above. If the weight of the counterweight selected above is wrong, and it is too heavy or too light It is very likely that the shaking of the ceiling fan will become larger, so it is necessary to choose a heavier or lighter weight, and then make a judgment on each fan blade in sequence until the ceiling fan shakes less and is not biased. Oblique, and when a more correct fan blade and a suitable weight are selected, the weight installed on the selected fan blade can be removed, and the replacement device can be replaced only on the opposite side of the fan blade. , This completes the detection of the ceiling fan. It can be known from the above detection methods that there are still the following shortcomings: (1) it is detected visually, and the detection result is likely to be completely wrong, and it is also very likely

Page 4 4 5 56 7 9 5 'Description of the invention (2) After the detection, the shaking of the ceiling fan becomes larger or smaller, so the position of the center of gravity of the ceiling fan cannot be judged and detected once and correctly. Covering the ground for testing, so the whole testing process is not only tedious, time-consuming, labor-intensive, and relatively expensive, so it is not economically beneficial; (2) When testing, it is only visually, and the ceiling fan shakes minimally and deflects. In the smallest case, it is possible to roughly judge and select the fan blades to be weighted. Therefore, this detection method is less reliable. It is impossible to make the ceiling fan rotate in a balanced manner, and the center of gravity is slightly biased to one side and shakes. C) If the ceiling fan is rotating at high speed after testing, it will cause the center of gravity of the ceiling fan to be sideways, which will cause great shaking, deflection or vibration. Therefore, after using for a period of time, the screw will shake and fall off. Loosening and falling of the entire ceiling fan create danger of danger and endanger life. In view of the above-mentioned lack of general knowledge, the inventor of the present invention is continually experimenting with processes and products in consideration of the creation of process methods. After many experiments and years of experience, he has improved the creation that is currently missing, and then introduced samples and applied for this. inventor. _ <Objective of the invention>
