Description

Technical Field

[0001] The invention relates to the field of linear modules, and in particular to a linear module capable of independent oil injection. Background Art

[0002] In the automation industry, linear modules are one of the commonly used mechanical equipment in automation equipment. Linear modules have different names in different industries. The more common names are: linear slide, linear slide, electric slide, robotic arm, etc. A slide is usually installed on the linear module, and other required workpieces are installed on the slide and a set of motor forward and reverse programs are set to make the workpiece automatically reciprocate, thereby achieving the purpose of mass production and intensive production of equipment.

[0003] In the existing linear modules, a motion unit is generally composed of a slider supporting a slide, wherein the slide reciprocates along the lead screw, and the slider reciprocates along the guide rail. In order to reduce the friction of the slide on the lead screw and the friction of the slider on the guide rail, lubricating oil needs to be injected into the slide and the lead screw as well as the slider and the guide rail. The existing linear modules usually adopt a set of lubrication pipeline system to solve this problem. All lubrication pipelines are connected in series and a single oil nozzle is used to supply oil. This kind of lubrication pipeline system will cause uneven oiling of the slide or slider when adding lubricating oil, and it is impossible to accurately oil the slide and the slider, so that the slide and the slider cannot be fully lubricated. Due to the large friction coefficient of the motion unit, jamming will occur, which seriously affects the motion accuracy of the linear module.

[0004] Therefore, it is necessary to develop a linear module that can accurately inject oil to the slide table and the slider independently. Summary of the invention
