[0104] 1. The detection device can detect the current disc turning device body before each disc turning, and store the disc turning device body when the disc turning device body is not needed;

[0105] The current disc turning device body is detected before each disc turning to avoid the current disc turning device being abnormal, and then the medium-speed disc turning is affected, the disc turning quality is affected, and the installation time is wasted;

[0106] 2. The static deviation is calculated based on the image processing module, the size deviation of the ratchet teeth and the size deviation of the driving block are calculated, and the maximum deviation state of the ratchet teeth The maximum deviation state of the driving block Obtain the overall deviation of the moving parts of the turning gear in static state;

[0107] And calculate the size deviation of the ratchet teeth and the size deviation of the driving block, both considering the length, width, height, volume of the corresponding deviation area to obtain the average value (such as ), and the maximum value (such as ), so that the calculation is more reliable;

[0108] 3. And perform motion simulation detection to obtain dynamic information of the moving parts (rotary disc speed, simulation piece speed, driving block vibration information, driving block moving speed, driving block displacement), and based on the deviation state of the rotary disc speed, the simulation piece speed The deviation state of the moving speed of the driving block And the displacement deviation state of the driving block (combined with the displacement times and displacement size) And the vibration frequency deviation state Obtain the dynamic deviation of the turning gear body, and the calculation is more reliable;

[0109] 4. When γ≥γ0, the first warning is performed, and the first speed sensor, the second speed sensor, the displacement sensor, the driving motor, the speed sensor, and the first vibration sensor do not work; γ0 is the first preset value corresponding to γ; when the static deviation is too large, the corresponding parts are checked and replaced in time;

[0110] When γ<γ0, control the first speed sensor, the second speed sensor, the displacement sensor, the driving motor, the speed sensor, and the first vibration sensor to work to obtain β; when the static deviation meets the requirements, obtain the dynamic deviation;

[0111] When γ<0.5γ0, and β≥β0, the second warning is performed; and according to the dynamic deviation result Provide a basis for adjusting the turning gear, realize that the static deviation is small, but the dynamic deviation is large, at this time the connection state of the parts of the turning gear body may be abnormal, at this time adjust the connection state of the parts of the turning gear body to ensure that the turning rotation movement is more reliable;

[0112] When 0.5γ0<γ<γ0, and β≥β0, the third warning is performed. Realize that the static deviation is large, and the dynamic deviation is large, and prefer to replace the corresponding parts before detection.

[0113] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
