Description
Technical Field
The utility model belongs to the field of linear motors, and particularly relates to a linear motor with a dustproof structure.
Background
The linear motor module is a transmission device which directly converts electric energy into linear motion mechanical energy without any intermediate conversion mechanism. The linear motor rotor, the magnetic track, the linear guide rail, the feedback encoder, the aluminum alloy base and the sliding body form the linear motor rotor. The linear motor module is an automatic upgrading unit of a relay synchronous belt and a ball screw linear transmission mechanism. The linear and curvilinear motion of the load is realized through the combination of all the units, so that the automation of the light load is more flexible and the positioning is more accurate.
However, the linear motor module has the performances of high speed, high acceleration and the like, and the magnetic track of the linear motor is of a strong magnetic structure. The dustproof structure is necessary for the safety of using the linear motor and the daily maintenance of the linear motor. The dust prevention of the linear motor module can be divided into a semi-dust prevention mode and a full-dust prevention mode. However, the two dust-proof methods have respective disadvantages in different application occasions:
to traditional half dustproof linear electric motor module:
the upper cover plate can only be fixed through the end plates at the two ends of the linear motor module, and the large part of the section bar is in a suspended state. Has high requirements on the combination property of the mechanical structure and the material of the cover plate. For the long-stroke single-shaft module and the gantry structure with high speed and high acceleration, the strength of the cover plate cannot meet the requirements of equipment. Even because of the operation of the module, the structure, material and fixing manner of the cover plate. The cover plate can vibrate and scratch the module, so that the precision of the linear motor module is influenced. Even the linear motor module can not normally operate.
For the full dust-proof linear motor module:
from the aspect of structure, the structure of full dustproof linear motor module is more complicated than that of half dustproof linear motor module. Besides direct contact between the guide rail and the slide block, the dust-proof steel belt of the linear motor module also has friction with a guide structure (an organ cover and a guide rail, a flat belt and a pulley). This results in a fully dustproof module that is not suitable for high speed and high acceleration applications. It is also determined that it is maintained more frequently on a daily basis than the semi-dustproof module. In addition, the cost is higher than that of a semi-dustproof module from processing to maintenance.
