Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical processing motion platforms, in particular to a double-station precision motion platform. Background Art

[0002] Many current granite precision motion platforms utilize a dual-station design. Dual-station technology is a highly efficient production model that allows two different tasks or processes to be performed simultaneously within the same machine or space. This design aims to improve production efficiency, reduce equipment idle time, and lower production costs. Especially in laser processing equipment, where the laser system costs a significant portion of the overall machine cost, a dual-station design is a crucial means of enhancing production continuity and flexibility.

[0003] However, most of the current double-station platforms adopt a left-right side-by-side form. When the product format is large, the left-right side-by-side approach will make the overall size of the granite base too large, thereby increasing the cost, weight and floor space of the motion platform, and the load-bearing requirements of the factory will also increase.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a dual-station precision motion platform to make it more valuable for industrial use. Utility Model Content

[0063] When the motion platform is working, the front of the platform is the loading position, the upper Y-axis fixture 303 loads the material, and then moves to the bottom of the Z-axis module 700 for processing. During the processing, the lower Y-axis fixture 203 loads the material and waits at the loading position; after the processing is completed, the lower Y-axis module 200 moves to the bottom of the Z-axis module 700 for processing, and the Z-axis compensates for the height difference. During the processing, the upper Y-axis fixture 303 loads the material and waits at the loading position; this rotation is used to achieve the purpose of cyclic loading and reduce the waiting time of the equipment.

[0064] The left-right direction mentioned in this article is the X-axis direction, the front-back direction is the Y-axis direction, and the vertical direction is the Z-axis direction.

[0065] The double-station platform design of this utility model improves production efficiency, reduces equipment idle time, and reduces production costs at the same time; the upper and lower stacking platforms reduce the width of the granite base, reduce costs, and reduce the load-bearing requirements for the factory building; it has a wide range of applications and can be used for laser processing, dispensing machines, AOI inspection and other equipment.
