Workbench action process:

Manually place the material box (0110) filled with the valve body on the corresponding position of the material box mounting plate (0117), the proximity sensor on the sensor bracket I (0111) senses that the material box (0110) is in place, and the rodless cylinder ( The slider on 0102) descends, driving the air claw (0106) to descend, and pushes against the buffer I (0120). After the slider slides in place, the magnetic switch on it sends a signal, and the air claw (0106) closes to grab a valve body, the proximity switch on it sends a signal, the slider rises, and the magnetic switch sends a signal when it is in place, the motor AI (0103) rotates, drives the ball screw (0105) to rotate through the coupling, and the entire pick-up mechanism passes through the sliding connecting plate ( 0108) Move to the right along the linear guide rail AI (0104), place the valve body on the line body, and repeat this action. When the first row of valve bodies is taken out, the motor BI (0113) in the feeding mechanism drives the ball wire The bar and the linear guide rail BI (0109) move the material box (0110) forward and bring the second row of valve bodies to the pick-up position. Repeat this action like this, after the valve body in the material box (0108) is taken, manually material box (0110) is taken away, changes the material box of filling valve body.

Working principle: Two sets of precision transmission chains composed of servo motor-ball screw-linear guide pair are used to ensure the accuracy of displacement in the vertical and horizontal directions; the combination of rodless cylinder-sensor-buffer limiter is used to Realize the fast and precise up and down movement of the air claw; use the air claw-solenoid valve-magnetic switch combination to control the timely opening and closing of the air claw; thus realize the functions of grabbing, feeding and changing the row of the valve body.
