[0046] The internal settings of the control panel 13 include a processor, a data collection module, a data analysis module, and an execution module. The data collection module collects the part preprocessing condition information on the preprocessing equipment during the surface preprocessing of medical metal parts. The preprocessing condition information consists of a water body cleaning factor, a sandblasting volume factor, and a disinfectant solution temperature factor, and transmits it to the data analysis module;

[0047] It should be noted specifically that: the water body cleaning factor represents the vibration frequency data of the vibration rod 19 collected by the vibration frequency sensor. The vibration frequency sensor is installed on the inner wall of the cleaning tank 12. The larger the water body cleaning factor, the better the cleaning effect of cleaning medical metal parts through water body vibration. The sandblasting volume factor represents the sandblasting volume data of the sandblasting port collected by the flow sensor. The flow sensor is installed at one end of the conveying pipe 40 close to the exhaust fan 39.

The disinfectant solution temperature factor represents the disinfectant solution temperature data collected by the temperature sensor. The temperature sensor is installed on the inner wall of the disinfection and sterilization tank 6. The larger the disinfectant solution temperature factor, the better the disinfection and sterilization effect of disinfecting medical metal parts through the disinfectant solution;

[0048] The data analysis module then performs part surface preprocessing control analysis operations based on the received part preprocessing condition information on the preprocessing equipment during the surface preprocessing of medical metal parts. The specific steps are as follows:

[0049] Step 1: Obtain the part preprocessing condition information on the preprocessing equipment during the surface preprocessing of medical metal parts, and calibrate the water body cleaning factor, the sandblasting volume factor, and the disinfectant solution temperature factor therein as Q, P, and X respectively;

[0050] Step 2: According to the formula: , obtain the preprocessing level R on the conveying table 3 during the surface preprocessing of medical metal parts, where a, b, and c are all process correction factors, c > b > a and ;

[0051] It should be noted specifically that: the larger the value of the preprocessing level R, the better the preprocessing effect on the surface of medical metal parts, enabling medical metal parts to meet subsequent processing requirements. There is a direct proportional relationship between the preprocessing level R and the water body cleaning factor Q, the sandblasting volume factor P, and the disinfectant solution temperature factor X, indicating that increasing the vibration frequency of the vibration rod 19, increasing the sandblasting volume, and increasing the disinfectant solution temperature can all improve the preprocessing effect on the surface of medical metal parts;

[0052] Step 3: When the pre-treatment level R of the medical metal part on the conveying table 3 during the surface pre-treatment process is greater than the maximum value of the preset range r, within the preset range r, or less than the minimum value of the preset range r, process excellent signal, process normal signal, and process poor signal are generated respectively;

[0053] And the process excellent signal, process normal signal, and process poor signal are transmitted to the execution module via the processor;

[0054] After receiving the process excellent signal, the execution module does not perform any processing;

[0055] After receiving the process normal signal, the execution module immediately controls to increase the vibration frequency of the vibration motor 20 and start the electric heating plate 5 to work. By increasing the vibration frequency of the vibration motor 20, the vibration frequency of the vibrating rod 19 is increased. By the work of the electric heating plate 5, the disinfectant liquid in the disinfection and sterilization tank 6 is heated to increase the temperature of the disinfectant liquid;

[0056] After receiving the process poor signal, the execution module immediately controls to increase the vibration frequency of the vibration motor 20, start the electric heating plate 5 to work, and start the movable motor 43 to work. By increasing the vibration frequency of the vibration motor 20, the vibration frequency of the vibrating rod 19 is increased. By the work of the electric heating plate 5, the disinfectant liquid in the disinfection and sterilization tank 6 is heated to increase the temperature of the disinfectant liquid. By the work of the movable motor 43, the movable turntable 45 is driven to rotate, the rotating connecting rod 46 is driven to move, the movable seat 48 and the movable block 50 are driven to move, the sliding sleeve 51 is driven to move, and the closing block 38 is driven to move upward along the opening, increasing the amount of abrasive blasting sprayed into the processing tank 9 from the abrasive blasting port;

[0057] Through the data collection module in the control panel 13, the part pre-treatment working condition information during the surface pre-treatment process of the medical metal part is collected, and the collected information is transmitted to the data analysis module. Through the processing of the data analysis module, the process excellent signal, process normal signal, and process poor signal are obtained. The obtained signals are transmitted to the execution module via the processor. Through the operation of the execution module, the surface pre-treatment process of the part is accurately controlled and adjusted. It can intelligently adjust the vibration frequency of the vibrating rod 19, the amount of abrasive blasting at the abrasive blasting port, the temperature of the disinfectant liquid, and the ratio among the three according to the specific situation in the surface pre-treatment of the part, and can perform efficient and sufficient pre-treatment operations on the part to ensure that the pre-treated part fully meets the requirements of subsequent processing.
