Description

Balanced mass damping system of high-precision chip mounter

Technical Field

The utility model relates to the technical field of chip mounters, in particular to a high-precision chip mounter balance mass damping system.

Background

When the chip mounter works, the mover on the portal frame is driven by the linear motor to move, so that the chip is sucked from the bearing workbench and then moved to the welding end to weld the fetched chip. When the linear motor receives the pulse to move or decelerate to stop, the portal frames can receive a reaction force with equal magnitude and opposite directions. In a working system without damping treatment, the opposite force can deform the portal frame, and vibration with different sizes is generated according to different materials used for the portal frame. Because the mover reciprocates frequently, the mover makes a round trip within about 1200 milliseconds, namely, the mover receives instantaneous force of acceleration and deceleration for 4 pulses in total, vibration generated by single impact cannot be completed in a system which does not do damping treatment, and the vibration effects are overlapped with each other finally.

The damping mode in the prior art is to use a damping system, namely, active or passive damping systems are added on two sides of a portal frame or the bottom of a workbench; this approach reduces the vibration amplitude and even stops the vibrations generated in the system by damping or counter-buffering. However, the disadvantage is that an additional damping control system is required, the damping effect is uneven due to the fact that the damping system judges the vibration frequency, and additional energy consumption is caused by the additional damping system.
