Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide table technology, and in particular discloses a fully enclosed linear motor slide table module with centralized oil injection. Background Technology
[0002] Linear motor slide modules are widely used in semiconductor equipment, precision machine tools, and other fields due to their high precision and high response characteristics. During high-speed movement, the sliding or rolling contact between the guide rail and the slider generates dry friction, leading to scraping or wear on the surface of metal materials. Lubricating grease can form an oil film between the contact surfaces, converting dry friction into fluid friction or mixed friction, significantly reducing friction loss. Traditional slide modules use an open guide rail design, requiring manual periodic addition of grease to the slider's oil injection hole. However, with the increasing use of cleanrooms and corrosive environments, fully enclosed slide modules have become the mainstream. The oil injection operation for fully enclosed slide modules is complex, requiring the removal of the steel strip or end cap to expose the internal slider, with each maintenance taking nearly 30 minutes, resulting in low efficiency. Therefore, there is an urgent need to develop a fully enclosed linear motor slide module that allows for centralized oil injection. Utility Model Content

Both ends of the steel belt are fixed to the base and cover the guide slot, forming a closed structure within the inner cavity. The mover seat is slidably installed in the inner cavity via the sliding assembly, and the mover seat has a worktable protruding from the guide slot. An oil nozzle is provided on the worktable, and the mover seat has an oil passage inside, one end of which is connected to the oil nozzle, and the other end of which extends toward the sliding assembly to form an oil outlet. External lubricating grease enters the oil passage through the oil nozzle and then flows to the friction surface of the sliding assembly through the oil outlet.
[0005] Furthermore, the sliding assembly has two parallel slide rails; there are two oil outlets, each facing one of the two slide rails, and external lubricating grease lubricates the two slide rails simultaneously through the two oil outlets.

[0007] Furthermore, the moving part has a slide, one end of which is mounted on the moving part, and the other end of which protrudes from the inner cavity of the base through a guide slot to form a worktable. The oil circuit has a first flow path and a second flow path. The first flow path is located inside the slide and the second flow path is located inside the moving part. The first flow path and the second flow path are connected, and the oil nozzle is connected to the first flow path.
[0008] Furthermore, the first flow path and the second flow path are arranged in parallel.

[0009] Furthermore, the oil circuit has two drain ports, which are located on opposite sides of the mover seat.
[0010] Furthermore, the inner cavity of the base has an oil collection groove and a guide slope, so that external lubricating grease seeps out from the friction surface and is guided to the oil collection groove through the guide slope.
[0011] Furthermore, the bottom of the oil collection tank has an oil drain port, through which the waste liquid in the oil collection tank is discharged from the base.
[0012] Furthermore, a sealing ring is provided between the first oil outlet and the second oil inlet.
