Traditional lubrication methods for linear module slides mainly rely on manual periodic application of grease or lubricating oil, which presents the following problems:

[0003] Uneven lubrication: Manual application makes it difficult to ensure uniform distribution of the lubricating medium, which can easily lead to localized wear and affect the smoothness of movement.

[0004] High maintenance costs: Frequent downtime for maintenance increases labor costs and reduces production efficiency.

[0005] Uncontrollable lubrication: Excessive lubrication may cause contamination, while insufficient lubrication will accelerate wear and is difficult to control precisely.

[0024] like Figures 1 to 3 As shown, the present invention proposes a linear module slide structure, including a linear module body 100 and a slide body 110. The slide body 110 can move along the length direction of the linear module body 100. Lubrication devices 200 are provided on both sides of the linear module body 100. The lubrication devices 200 include a driving device and a storage container 230. The storage container 230 is fixed to both sides of the slide body 110 by fasteners 220. A sealing piston 260 is provided inside the storage container 230. The driving device is used to drive the sealing piston 260 to squeeze out the lubricating medium in the cavity of the storage container. A lubrication channel 111 is provided on the slide body 110. The lubricating medium enters the slide rail of the linear module body 100 through the lubrication channel 111.

[0025] The sealing piston 260 is driven by a drive device to squeeze out the lubricating medium, which is then transported to the slide rail through the lubrication channel 111 to achieve automatic lubrication.

[0026] The drive unit includes a drive motor 210, a reciprocating lead screw 240, and a lead screw nut 250, with the reciprocating lead screw 240 and lead screw nut 250 engaging with each other. The lead screw nut 250 is embedded within a sealed piston 260. The drive motor 210 drives the reciprocating lead screw 240 to rotate, causing the sealed piston 260 to move and extrude the lubricating medium. The drive unit uses a motor 210 to drive the reciprocating lead screw 240, with the lead screw nut 250 embedded in the sealed piston 260. When the motor rotates, it drives the piston to move, thereby extruding the lubricating medium.

[0027] The storage container 230 is a detachable structure and is fixedly connected to the slide body 110 by fasteners 220. The storage container 230 is fixed to the slide by fasteners 220 and can be removed to replace or replenish the lubricating medium.

[0028] The lubrication channel 111 is a multi-branch channel, evenly distributed on the contact surface between the slide body 110 and the linear module body 100. The multi-branch structure of the lubrication channel 111 ensures that the lubricating medium is evenly distributed on the contact surface between the slide and the slide rail.

[0029] The drive motor 210 is a stepper motor or a servo motor, and its output shaft is directly connected to the reciprocating lead screw 240 or connected through a coupling. The drive motor 210 is a stepper motor or a servo motor, which can precisely control the speed and stroke, and ensure that the lubrication amount is controllable.

[0030] The sealing piston 260 is made of corrosion-resistant material and has a sealing ring on its outer edge to ensure the airtightness of the cavity of the storage container 230. The sealing piston 260 uses corrosion-resistant materials such as PTFE and is equipped with a sealing ring to ensure the airtightness of the storage container 230.

[0031] The lubrication device 200 also includes a control module, which controls the start and stop of the drive device based on the moving distance or time interval of the slide body 110. The control module automatically starts and stops the drive device based on the moving distance or time interval of the slide, achieving lubrication on demand.

[0032] The slide rail surface of the linear module body 100 is coated with a wear-resistant coating, and the lubricating medium is a high-viscosity grease or lubricating oil. The slide rail surface is coated with a wear-resistant coating such as DLC or ceramic, and a high-viscosity grease or lubricating oil is used.

[0033] In summary, the slide body 110 can move along the length of the linear module body 100. Lubrication devices 200 are provided on both sides of the linear module body 100. The lubrication device 200 includes a drive device and a storage container 230. The storage container 230 is fixed to both sides of the slide body 110 by fasteners 220. The storage container 230 has a sealing piston 260 inside. The drive device is used to drive the sealing piston 260 to squeeze out the lubricating medium in the cavity of the storage container. It should be noted that the slide body 110 is provided with a lubrication channel 111. After the lubricating medium is squeezed out, it enters the slide rail of the linear module body 100 through the lubrication channel 111 to achieve the lubrication effect.

[0034] The drive device includes a drive motor 210, a reciprocating lead screw 240 and a lead screw nut 250. The reciprocating lead screw 240 and the lead screw nut 250 cooperate with each other. The lead screw nut 250 is embedded in the sealing piston 260, so that the sealing piston 260 can be moved and squeeze out the lubricating medium under the drive action of the drive motor 210.
