Description

Technical Field

[0002] The traditional linear motor driven gantry structure usually adopts a two vertical and one horizontal bed frame structure. The X-axis beam is rigidly fixed on two mutually parallel Y-axis linear motor drive mechanisms. The X-axis beam can only move in the Y direction and cannot rotate. However, the above-mentioned gantry has the following disadvantages: it is affected by the processing accuracy and installation accuracy, and the verticality of the beam and the two Y-axis directions is difficult to adjust. At the same time, if the parallelism and synchronous drive between the two Y-axis guide mechanisms are not guaranteed well, internal stress will be generated between the systems when the beam is running, which will increase the friction of the guide mechanism and affect the life of the guide mechanism. Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative flexible linear motor dual-drive gantry platform to overcome the above-mentioned defects in the prior art.
