Abstract

A method and a device for controlling the cantilever crossbeam of a full automatic chip mounter to perform high-precision synchronous motion along the Y axis relate to the field of chip mounter control and aim to solve the problem that in the motion process of the cantilever crossbeam of the full automatic chip mounter along the Y axis, moving speeds and displacement of two ends of the cantilever crossbeam are asynchronous. According to the method and device for controlling the cantilever crossbeam of the full automatic chip mounter to perform high-precision synchronous motion along the Y axis, signals collected by a first magnetic railing ruler and a second magnetic railing ruler are guided into a motion control module, and a pulse signal sent to a second servo driver is revised by using software in the motion control module, so the aim of compensating the pulse error of the two magnetic railing rulers to the second servo driver in a mode of amending a pulse frequency in the shortest sampling time is ensured, and the moving speeds of the two ends of the cantilever crossbeam are controlled to be same. The method and device for controlling the cantilever crossbeam of the full automatic chip mounter to perform high-precision synchronous motion along the Y axis are suitable for controlling the cantilever crossbeam of the full automatic chip mounter to move along the Y axis.

Description

technical field [0001] The invention belongs to the field of chip mounter control. Background technique [0002] The fully automatic placement machine is the most important and most complex equipment on the entire (SMTSurfaceMountedTechnology, surface mount technology) production line. The motion control system of the automatic placement machine is divided into four parts: X, Y, Z, and θ axes. The automatic placement machine has high requirements on the control of the Y-axis, and the bilateral position error of the cantilever beam is required to be within 0.3mm during operation. Exceeding this error will not only affect the placement accuracy of the chip but also cause damage to the mechanical structure such as the cantilever beam. Arch-type structure automatic placement machine, the cantilever beam moves along the Y-axis direction, and the span of the cantilever beam is relatively large. If the cantilever beam is driven on one side, the mechanical requirements are too high...
