[0002] A linear slide module is a mechanical device that enables high-precision linear reciprocating motion. It is widely used in automation equipment, CNC machinery, laser equipment and other scenarios. It is usually composed of a base, a slider, a guide rail and a lead screw. In use, the linear slide module drives the lead screw to rotate through a motor, thereby driving the slider to move linearly along the outside of the guide rail.

[0003] However, existing linear slide modules lack dust protection structures during use. During long-term operation, dust, metal shavings, oil stains, etc. can easily enter the guide rails and lead screws, causing uneven movement or even jamming, thus reducing the service life of the linear slide module. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a linear slide module with a dustproof protection mechanism, which aims to improve the problem in the prior art that dust, metal shavings, oil stains and other contaminants can easily enter the guide rail and lead screw during long-term operation, resulting in uneven movement or even jamming.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4This utility model provides an embodiment of a linear slide module with a dustproof protection mechanism, comprising: a base 1; fixed blocks 2, which are fixedly connected to the outer sides of the base 1; a lead screw 5, which is rotatably connected to the outside of the two fixed blocks 2; a slider 7, which is threadedly connected to the middle of the lead screw 5; a telescopic protective shell 9, which is disposed outside the two fixed blocks 2 and the slider 7; a locking block 10, which is fixedly connected to the outer sides of the telescopic protective shell 9; a moving block 25 and a protrusion 12, which are slidably connected inside the two fixed blocks 2 and the slider 7, and the protrusion 12 is fixedly connected to the top of the moving block 25; a spring 13 and a plug 14, which are fixedly connected to the bottom of the moving block 25 and the plug 14 is fixedly connected to the top of the moving block 25; and a lubrication assembly, which is used to lubricate the lead screw 5. Mounting grooves 24 are provided on the outside of both the fixed blocks 2 and the slider 7, and the two locking blocks 10 are connected to the two mounting grooves 24. The locking block 2 and the slider 7 are both provided with through holes 11 on their upper parts. The protrusion 12 is slidably connected inside the through hole 11. The through hole 11 facilitates the movement of the protrusion 12. The locking block 2 and the slider 7 are both provided with through holes 26 inside. The insertion block 14 is slidably connected inside the through hole 26. The through hole 26 facilitates the movement of the insertion block 14. The locking block 10 is provided with a locking groove 15 inside. The insertion block 14 is inserted into the locking groove 15. The slider 7 is fixedly connected to baffles 8 on both sides of its exterior. The base 1 is fixedly connected to a slide rail 6 on its top. The bottom of the slider 7 is slidably connected to the outside of the slide rail 6. The right side of the locking block 2 is fixedly connected to a support block 3. The support block 3 is fixedly connected to the top of the support block 3. The support block 3 facilitates the fixing of the motor 4. The lead screw 5 is fixedly connected to the output end of the motor 4. By starting the motor 4, the lead screw 5 fixed at the output end rotates. The rotation of the lead screw 5 causes the slider 7, which is externally threaded, to move outside the slide rail 6, thus completing the linear movement.

[0035] Specifically, during the installation of the telescopic protective shell 9, firstly, the protrusions 12 inside the fixed block 2 and the slider 7 need to be moved synchronously. When the protrusions 12 move, they drive the movable block 25 fixed at its bottom to move synchronously. Since the top structure of the movable block 25 is fixedly connected to the insert block 14, the movement of the movable block 25 will directly drive the insert block 14 to make synchronous linear motion. During this process, the movement of the movable block 25 will compress the spring 13 installed at its bottom. The spring 13 is thus compressed and undergoes elastic deformation, storing elastic energy. Subsequently, as the insert block 14 gradually disengages from the mounting groove 24 inside the fixed block 2 and the slider 7 during the movement, the outer sides of the telescopic protective shell 9 can be pre-installed. The installed locking blocks 10 are aligned and inserted into the mounting slots 24 corresponding to the positions on the outside of the fixing block 2 and the slider 7, respectively, to achieve the initial positioning and fixation of the telescopic protective shell 9. After the locking blocks 10 and the mounting slots 24 are engaged, the protrusion 12 is released. At this time, under the reaction force of the spring 13, the moving block 25 and the insert block 14 connected to its top are pushed to reset. Finally, the insert block 14 will be inserted into the locking slot 15 inside the locking block 10, thereby completing the installation of the telescopic protective shell 9. Through the above installation operation, the telescopic protective shell 9 is firmly fixed to the outside of the linear slide module. Its main function is to prevent dust, metal shavings, cutting fluid and other pollutants from the external environment from entering the inside of the module, thereby extending the service life of the slide module.

[0036] Reference Figures 2-5 The lubrication assembly includes a reservoir tube 17, which is fixedly connected to the inside left side of the slider 7. A micro pump 19 is fixedly connected to the front side of the slider 7. The input end of the micro pump 19 is fixedly connected to the inside of the reservoir tube 17, and the output end of the micro pump 19 is fixedly connected to a delivery tube 20. A nozzle 22 is fixedly connected to the top of the delivery tube 20. The nozzle 22 facilitates the spraying of lubricating fluid onto the outside of the lead screw 5. A filling port 18 is fixedly connected to the top of the reservoir tube 17. A sealing cap is installed on the top of the filling port 18. The filling port 18 facilitates the filling of lubricating fluid. A fixing ring 21 is fixedly connected to the front side of the slider 7. The delivery tube 20 is slidably connected inside the fixing ring 21. The fixing ring 21 facilitates the fixation of the delivery tube 20. A fixing ring 23 is fixedly connected to the outside of the nozzle 22. The bottom of the fixing ring 23 is fixedly connected to the outside of the slider 7. The fixing ring 23 facilitates the fixation of the nozzle 22.

[0037] Specifically, when lubricating the lead screw 5 of the linear module, firstly, lubricant is injected into the reservoir 17 through the filling port 18. After the lubricant is injected, the micro pump 19 is started. The micro pump 19 draws the pre-injected lubricant from the reservoir 17. Then, under the action of the micro pump 19, the lubricant is transported to the nozzle 22 through the delivery pipe 20. When the lubricant reaches the nozzle 22, it is evenly sprayed onto the surface of the lead screw 5 through the nozzle 22, reducing the direct contact between the lead screw 5 and the slider 7, reducing frictional resistance, and preventing problems such as overheating, jamming or damage caused by long-term operation, thereby improving the stability of the lead screw 5 operation.

[0038] Working principle: When installing the telescopic protective shell 9, firstly, the protrusions 12 inside the fixed block 2 and the slider 7 are moved synchronously. When the protrusions 12 move, the bottom fixed moving block 25 moves, and the top fixed insert block 14 moves. At the same time, when the moving block 25 moves, it squeezes the bottom fixed spring 13, causing the spring 13 to deform under force. Then, when the insert block 14 disengages from the mounting groove 24 opened inside the fixed block 2 and the slider 7, the locking blocks 10 fixed on both sides of the telescopic protective shell 9 are respectively locked into the mounting groove 24 opened outside the fixed block 2 and the slider 7. Finally, when the protrusions 12 are released, under the reaction force of the spring 13, the insert block 14 is inserted into the slot 15 opened inside the locking block 10. Thus, the telescopic protective shell 9 can be installed on the outside of the linear slide module. The telescopic protective shell 9 can prevent dust, metal shavings, cutting fluid and other contaminants from entering the module, thereby extending the service life of the slide module and reducing the failure rate.

[0039] When lubricating the lead screw 5 of the linear module, firstly, lubricant is added into the reservoir 17 through the filling port 18. Then, the micro pump 19 is started to draw lubricant from the reservoir 17. Subsequently, the lubricant is delivered to the nozzle 22 through the delivery pipe 20. Finally, the lubricant is sprayed onto the lead screw 5 through the nozzle 22, thus lubricating the lead screw 5. This facilitates the lubrication of the lead screw 5 of the linear module, and the lubrication enables the lead screw 5 to operate continuously and stably, reducing sudden failures and improving the stability of the lead screw 5's operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
