A fully sealed steel belt linear motor module with rollers

Abstract

The invention provides a fully-sealed steel belt type linear motor module with rollers and relates to the field of linear motors. According to the technical scheme of the invention, the two ends of a rotor installation plate along the width direction are fixedly provided with roller plates and the roller plates are fixedly provided with an object stage. The two ends of a bottom plate along the length direction are provided with end plates. The two ends of the bottom plate along the width direction are provided with lateral baffle plates. An upper cover plate is arranged on the end plates and the lateral baffle plates. The upper cover plate is provided with a square groove. The roller plates are capable of moving within the square groove. A square steel strip is arranged between the roller plates and the object stage. The square steel strip covers the square groove. According to the technical scheme of the invention, through arranging the end plates and the lateral baffle plates at the periphery of the bottom plate, arranging the upper cover plate on the end plates and the lateral baffle plates and arranging the square steel strip above the square groove to cover the square groove, the steel belt type linear motor module is fully sealed. Therefore, dusts, foreign matters and the like cannot get inside the linear motor, so that the linear motor can be applied in harsh environments. Meanwhile, the linear motor is prevented from being maintained and the service life of the linear motor is prolonged.

Description

technical field [0001] The invention relates to the field of linear motors, in particular to a fully sealed linear motor module. Background technique [0002] Linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotary motor that is cut radially and developed into a plane. Linear motors have gradually replaced ball screws and become the mainstream for driving linear motion. [0003] In the prior art, there are many linear motor modules with closed requirements, which are mainly protected by bellows. The bellows are arranged on both sides of the loading platform. The organ shield of the module shrinks, while the organ shield on the other side of the stage will extend, which can prevent dust and debris from entering the module to a certain extent. However, with the above protection methods, the protection level is not high when used in harsh e...

AI Technical Summary

Problems solved by technology

However, with the above protection methods, the protection level is not high when used in harsh environments, and dust and foreign matter are easy to enter the linear motor, which is troublesome to clean and maintain, and affects the performance. In addition, the organ cover is mostly made of three-proof cloth. Easily damaged, pierced or scratched by laser or iron core, and the service life is not long
