Summary of the invention

To this end, the present invention provides an RPC cover plate intelligent preparation system to overcome the problem that the RPC cover plate preparation system in the prior art lacks necessary detection and parameter adjustment means, resulting in low qualification rate and production efficiency of RPC cover plate preparation.

To achieve the above object, the present invention provides an RPC cover plate intelligent preparation system, comprising:

A mixing module, which is used to complete dry mixing and water mixing of RPC cover plate raw materials;

A molding module, which is arranged at the output end of the stirring module, comprises a cover plate mold for casting and molding, a feed port arranged above the cover plate mold, and a first belt conveyor arranged below the cover plate mold for supporting and conveying the cover plate mold;

A vibrating module, which is arranged at the output end of the forming module and vibrates the cast cover plate based on vibration;

A first testing module, which is arranged at the output end of the primary curing module, and is used to detect the surface image and elastic modulus of the cover plate after the primary curing and demoulding;

A final curing module, which is arranged at the output end of the first test module, and is used to perform final curing on the cover plate that meets the preset standard in the initial curing, wherein the final curing is to complete heating, constant temperature and cooling treatment in a constant humidity environment;

A second testing module, which is arranged at the output end of the final curing module, and is used to detect the compressive strength of the cover plate after the final curing;

a process determination module, which is connected to the first test module and the second test module respectively, determines the initial evaluation value of the cover plate based on the result of the detection by the first detection module, and determines whether the cover plate after the initial curing meets the preset standard according to the initial evaluation value of the cover plate, and determines whether the cover plate after the final curing meets the preset standard according to the compressive strength measured by the second test module;

A parameter adjustment module is respectively connected to the process determination module, the stirring module, the molding module, the vibration module, the calendering module, the primary curing module and the final curing module, and is used to adjust the operating parameters of the system according to the results determined by the process determination module.

Furthermore, the initial evaluation value of the cover plate is set to L, which is obtained by formula (1):

In formula (1), λ is the defect evaluation coefficient, which is set to 1025, β is the elasticity evaluation coefficient, which is set to 0.86, Sj is the area of the jth defect in the single surface pattern of the cover plate detected by the first test module, j=1,2,3...n, n is the total number of defects in the surface pattern of the cover plate, and the defects include holes and cracks, S0 is the surface area of the single cover plate, E is the elastic modulus of the cover plate, and E0 is the elastic modulus threshold.

The process determination module determines whether the operation of the vibration module meets the preset standard according to the vibration module evaluation value, or marks the cover plate as a second-level defective cover plate. The process determination module determines whether the operation of the initial curing module meets the preset standard according to the proportion of the cover plates marked as second-level defective cover plates within the preset time.

Furthermore, the evaluation value of the vibration module is set to Q, which is obtained by formula (2):

In formula (2), Li is the initial evaluation value of the i-th first-level defective cover plate, i=1, 2, ...n, and n is the total number of first-level defective cover plates marked within a preset time period.

Furthermore, the increase in the vibration frequency is positively correlated with the difference in vibration module evaluation values.

Furthermore, the process determination module is provided with several correction methods for the increase of the vibration frequency under the first preset condition, and each correction method has a different correction amplitude for the increase of the vibration frequency; under the first preset condition, the vibration module completes the increase of the vibration frequency and after the vibration frequency is increased, the hardness difference between the upper and lower surfaces of the cover plate is greater than a preset hardness difference threshold.

Furthermore, the process determination module determines whether the operation of the primary cultivation module meets the preset standard according to the proportion of the second-level defective cover plates marked within the preset time period, wherein:

If the proportion is less than the preset proportion threshold, the process determination module determines that the operation of the initial culture module meets the preset standard, and increases the dry mixing time of the mixing module for the raw materials within the next preset time period based on the difference between the preset proportion threshold and the proportion;

If the proportion is greater than or equal to a preset proportion threshold, the process determination module determines that the operation of the primary curing module does not meet the preset standard and increases the constant temperature curing temperature of the primary curing module within the next preset time period.

Furthermore, when the process determination module determines that the optimization of the initial curing module does not meet the preset standard based on the comparison result of the initial evaluation value of the cover plate after adjustment with the initial evaluation value of the cover plate before adjustment under the second preset condition, the constant temperature curing time of the initial curing module is increased within the next preset time. The second preset condition is that the process determination module completes the adjustment of the temperature of the constant temperature curing of the initial curing module.

Furthermore, when the process determination module determines based on the compressive strength that the cover plate that has completed final curing does not meet the preset standard, the cooling rate of the cooling treatment of the final curing module within the next preset time period is reduced, or the humidity inside the final curing module within the next preset time period is reduced.

Furthermore, the present invention fits the initial evaluation value of the cover board based on the surface defect area ratio collected by the image and the elastic modulus of the cover board, so as to scientifically and accurately evaluate the performance of the cover board after initial curing.

Furthermore, when the present invention determines that the cover plate after initial curing does not meet the preset standard based on the initial evaluation value of the cover plate, it determines whether the operation of the vibration module or the initial curing module meets the standard by marking the defective grade of the cover plate and determining the quantity and proportion.

Furthermore, the present invention determines the evaluation value of the vibration module based on the initial evaluation value and quantity of the first-level defective cover plates, thereby accurately determining the operating status of the vibration module.

Furthermore, the present invention determines whether the operation of the vibration module meets the preset standard based on the evaluation value of the vibration module, thereby accurately determining the operating parameters of the system in the next time period.
