The advantages of this utility model are: accurate counting, small error, and easy packaging after counting.

The invention relates to an optical mark positioning device for PC component mold visual inspection and a detection method. The method comprises the following detection steps: step 1, a preparation stage: selecting a base matched with the height of a to-be-detected mold, assembling the optical mark positioning device, and loading component quality inspection data by a machine vision system background; secondly, a mold and a mark are placed, specifically, an operator places the PC component mold on a mold table, and then an optical mark positioning device is adsorbed to the mold table according to a preset rule; step 3, triggering detection: triggering a machine vision system; step 4, image acquisition and processing: shooting by a camera, and identifying an optical mark and identification information thereof in an image by software; the machine vision system calculates the actual position and posture of the mold according to the marked position, the actual position and posture are compared with standard data, and whether the mold is qualified or not is judged; and step 6, result feedback and mark removal: the HMI displays the result, and the magnetically attracted mark positioning device is taken down from the mold table for storage after the detection is completed.

The application discloses a small household grey water treatment device, which comprises a tank body buried underground, a replaceable filter unit arranged in the middle of the tank body, a grey water precipitation unit arranged at the front end of the filter unit, and a water outlet sterilization unit arranged at the rear end of the filter unit; the grey water to be treated flows into the grey water precipitation unit to remove ash, is then pumped into the filter unit for filtration, and is discharged after sterilization by the water outlet sterilization unit. In the small household grey water treatment device, the tank body is buried underground, so that the occupied area of the ground can be greatly saved; moreover, the filter units at all levels can be flexibly taken out to replace filter elements, and the accumulated ash can be conveniently cleaned, so that the use and maintenance are extremely convenient.

The utility model discloses a portable charging fan, including fan body, fan body has the air outlet part, the characteristic is detachably provided with the mosquito repellent ring with mosquito repellent function on the fan body, and the mosquito repellent ring is set around the air outlet part, and the air outlet part is located in the mosquito repellent ring. The advantage is simple structure, and the mosquito repellent ring is integrated detachably on the fan body, so that the mosquito repellent function is combined with the fan function, and it is unnecessary to carry the mosquito repellent liquid, mosquito repellent bracelet and other equipment extra, reduces the travel burden, and improves the convenience of outdoor use. The mosquito repellent ring is detachably installed on the fan body, and the user can flexibly install or remove the mosquito repellent function according to the demand, without complex operation. The mosquito repellent ring is set around the air outlet part, does not occupy additional space, does not significantly increase the volume or weight of the fan, is convenient for keeping the light and nimble characteristics of portable fan, simultaneously also does not affect the air supply effect, and the mosquito repellent component on the mosquito repellent ring can be driven to diffuse along with airflow when the fan operates, increases the mosquito repellent range, and improves the mosquito repellent efficiency.

The invention discloses a singular value decomposition and wavelet threshold denoising combined signal processing method and system. The method comprises the following steps: acquiring a noise-containing fault signal; performing matrix conversion and singular value decomposition on the fault signal, and calculating an energy contribution value of each singular value; and processing the wavelet decomposition coefficient for the singular value of which the energy contribution value is higher than a set threshold value by adopting an improved threshold value and a threshold value function, and reconstructing an original signal through inverse wavelet transformation. By implementing the method provided by the invention, more flexible and effective denoising can be realized, and the accuracy and reliability of fault detection are improved.
