[0001] The utility model relates to the technical field of linear modules, in particular to a linear module that does not require disassembly, oiling or maintenance. Background Art

[0002] There are several names for linear modules, such as linear modules, rectangular coordinate robots, linear slides, etc. They are automated upgrade units following linear guides, linear motion modules, and ball screw linear transmission mechanisms.

[0003] The linear modules currently on the market often require disassembly of their external parts during long-term use before the internal slide rails can be oiled and maintained. However, disassembly of the external parts is inconvenient, and improper disassembly may also lead to the risk of damage.

[0004] For example, a linear module with disassembly-free oiling and maintenance disclosed in announcement number CN217761724U has an oiling nozzle installed on the slider and the lead screw nut, and the oiling nozzle is connected to the oiling holes of the slider and the lead screw nut. The staff can directly oil the slider, guide rail and lead screw nut through the two oiling nozzles for maintenance without removing any parts such as the upper cover. There is no risk of disassembly, low maintenance cost and quick and convenient use.

[0005] However, the device is unable to clean impurities adhering to the surface of the screw during use, thereby affecting the transmission accuracy of the linear module.

[0006] For this reason, we urgently need to provide a linear module that does not require disassembly and oil injection maintenance. Utility Model Content

[0029] The cleaning unit is arranged on the right side of the nut seat 5, the impurity removal unit is arranged at the lower end of the cleaning unit, and the sweeping unit is arranged at the bottom of the nut seat 5.

[0030] The cleaning unit includes a motor 2 601, a driving shaft 602, a gear 1 603, a driven shaft 604, a gear 2 605 and a brush roller 606.
