Turntable machine is a kind of high-precision equipment, mainly used in the back end of mold production or injection molding products, the processed products, through the servo motor as the power of the transmission system, rotate a certain point of view for stopping, for the manipulator to grab. The cooperation between the turntable and the manipulator is very tacit, and the motion model can be imagined to be similar to the industrial "dining table". If the positioning accuracy is not good, it will lead to the difficulty of the manipulator "not being able to clamp the dish".
The principle of the equipment is: a circular turntable, on which the workpiece can be placed, the two-station turntable machine is driven by the motor reducer, the reducer drives the turntable through the gear meshing small wheel with the large wheel, and the mechanical station is completed in the positive rotation between station 1 and station 2.
At present, the turntable machine in the mall has the following problems:
1. Processes such as glue melting, mold opening and closing, and injection are controlled by ordinary motors and hydraulic valves, with poor control accuracy and high energy consumption.
2. The rotation of the turntable is driven by a hydraulic motor, and then an external signal is used to decelerate and park. The positioning speed is slow, the accuracy is not high, and the wear and tear of the positioning pin is serious.
Based on this, customers in the toy manufacturing profession in Dongguan need to transform their equipment.
According to the needs of customers, INVT provides customers with a solution plan for non-standard vocational aircraft. In this plan, INVT DA200 servo software through non-standard customization, built-in servo point function, and then select multiple turns of positive value with memory function encoder, the data of the turntable is like a scale on the servo motor to complete the positioning, power off and restart any direction can be no longer need to find a reference point.
INVT Program Advantages
1. Use the DA200 servo internal return to origin function to find the origin. Generally, in order to find the origin of the switch to find the Z signal back, followed by a section of the way to offset, just about the initial device, the back of the machine can be recalled without dismantling.
2. Correct the given speed parameters of the interval point interval and analog quantity through the parameters. Through the IO trigger pathway.
3. Use the positive orientation mode, so that after the point is interrupted, you can continue to walk left or right to the fixed station. This is the end of the inching function.
Customer benefits
1. The turntable is controlled by an independent servo motor, the positioning accuracy can reach 0.16 minutes (1 degree = 60 minutes), the turntable speed can be adjusted arbitrarily, the turntable controlled by the servo motor rolls more smoothly, and the output power can be increased by 30%-50%.
2. The computer accurately monitors the orientation of the servo motor position of the turntable at station 1 and station 2, and if it is in place, there will be a signal to give it to prevent the direction from damaging the turntable when the cylinder moves, and the real high power! High coping! High precision!
Taking the 85-ton two-station disc machine as an example, the positioning time of the turntable rotating 180° < 1.5s
As a non-standard servo, DA200 for turntable machine integrates servo drive and PLC function, which is tailored for the professional type of turntable machine. Through a long period of shopping mall verification, it has been proved that it can help customers increase the power by 30%-50%, simplify the complex, simplify the operation performance of the host computer system, and improve the real end, high power! High coping! High precision
