From operation to maintenance: Efficient use guide for diagonal arm screen printing machine
The operation process should follow the "three-level preparation method". Before starting up, it is necessary to check the lubrication status of the inclined arm rotating joint to ensure that the movement is not stuck; Calibrate the printing origin through the touch screen to control the positioning error within 0.02mm; Select scraper hardness based on substrate material - use 65 ° polyurethane scraper for printing plastic parts, and switch to 80 ° steel scraper for metal curved surfaces. During the printing process, the pressure curve displayed on the touch screen should be monitored in real time. When the fluctuation exceeds ± 2N, the machine should be stopped immediately to check the tension of the screen.
Daily maintenance focuses on three core areas. After daily homework, clean the screen and scraper with a special solvent to avoid ink curing and blocking the mesh holes; Check the oil level of the harmonic reducer inside the inclined arm every week. If it is lower than 1/3 of the scale line, special gear oil should be replenished; Clean the linear guide rail for dust prevention every month and lubricate the slider with Vaseline. The practice of a certain factory shows that adhering to standardized maintenance can extend the equipment failure interval to over 800 hours.
Fault handling requires mastering the principle of "simplicity first, complexity later". If there is an angle positioning deviation, priority should be given to checking whether the connection wire of the absolute value encoder is loose; When the printed pattern is blurry, it is necessary to first check whether the tension of the screen has decreased (the standard value is 25-30N/cm), and then consider the parameters of the servo motor. For sudden arm jamming, the "zero calibration" can be performed after emergency stop reset, and 90% of minor faults can be resolved through this operation.
This set of guidelines deeply binds equipment performance with operating standards, ensuring the stability of printing accuracy and reducing downtime losses through preventive maintenance, keeping the diagonal arm screen printing machine in an efficient operating state at all times.
