Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0027] Please see Figures 1 to 4A fully sealed, dustproof industrial robot reducer includes a reducer body 1, a sealing shell 2 fitted over the reducer body 1, a connecting groove 3 on the outer wall of the sealing shell 2, and a mounting groove 4 above the connecting groove 3. A ventilation mechanism 5 is installed inside the mounting groove 4. The ventilation mechanism 5 includes a rubber plate 501 rotatably connected inside the connecting groove 3. A rotating rod 502 extends through the rubber plate 501, and a driven gear 503 is fixedly mounted at one end of the rotating rod 502. An active gear 503 is rotatably connected to the outer wall of the driven gear 503. Gear 504, drive rod 505 extends through the inside of drive gear 504, micro motor 506 is fixedly installed at the bottom of drive rod 505, plasma fan rod 507 is embedded in the lower part of the inside of the mounting groove 4, dust collection electrode 508 is embedded on both sides of the inside of the mounting groove 4, filter screen 509 is embedded in the top of the inside of the mounting groove 4, rubber plate 501 forms a rotating structure with connecting groove 3 through rotating rod 502, connecting groove 3 communicates with mounting groove 4, drive rod 505 passes through the inside of drive gear 504, drive gear 504 meshes with driven gear 503.

[0028] By adopting the above technical solution, the sealing shell 2 firstly protects the reducer body 1, protecting the internal components from exposure and dust accumulation, which could affect lubrication or even cause wear. The micro motor 506 operates, and under the rotation of the drive rod 505, the active gear 504 and driven gear 503 work together to rotate the rotating rod 502, driving the rubber plate 501 to rotate. Depending on the weather, the connecting groove 3 and the mounting groove 4 of the sealing shell 2 are sealed to prevent adverse weather conditions from affecting the internal components. Under normal conditions, the rubber plate 501 is open, and in conjunction with the plasma fan 507, it increases the gas flow speed to maintain heat dissipation and allows dust and impurities to carry charged ions. Simultaneously, the air filters 509 on both sides allow dust and impurities to flow close to the dust collecting electrode 508, where they are adsorbed, effectively filtering dust and preventing it from entering the sealing shell 2 and affecting the operation of the reducer body 1. The micro motor 506, plasma fan 507, and dust collecting electrode 508, among other energized components, are connected to the control terminal and cables of the industrial robot.

[0029] Specifically, such as Figure 4 and Figure 5As shown, a sealing plate 6 is fixedly installed on one side of the outer wall of the sealing shell 2, which is connected to the groove 3. A storage mechanism 7 is provided on one side of the sealing plate 6. The storage mechanism 7 includes an insertion frame 701, which is slidably connected to the inside of the placement groove 4. A storage groove 702 is opened inside the insertion frame 701. A rotating frame 703 is rotatably connected to the outer wall of the dust collection electrode 508. An insertion rod 704 is fixedly installed on the rotating frame 703 facing the outer wall of the dust collection electrode 508. A rotating locking block 705 is fixedly installed at one end of the insertion rod 704 that penetrates into the sealing shell 2. A rubber scraper 706 is fixedly installed on one side of the insertion rod 704 on the outer wall of the rotating frame 703.

[0030] By adopting the above technical solution, dust can be cleaned regularly. For example, after a day's work, the plasma fan bar 507 and dust collection electrode 508 can be closed. Then, the micro motor 506 can be started to make the rubber plate 501 rotate, which will make it fit the filter screen 509 and generate a vibration to shake off the dust. At the same time, the rubber plate 501 abuts against the rotating frame 703 and rotates stably with the cooperation of the insertion rod 704 and the rotating block 705, which makes the rubber scraper 706 fit against the dust collection electrode 508 and rotate, thereby scraping off the adsorbed dust. Finally, the dust falls into the collection slots 702 at both ends of the insertion frame 701 for unified collection, which is convenient for unified cleaning after the sealing plate 6 is disassembled and installed.

[0031] Working Principle: First, a sealing shell 2 is installed on the outside of the reducer body 1 to protect the internal components and prevent direct contact with external dust. Rubber plates 501 are installed inside the connecting groove 3 and the mounting groove 4 of the sealing shell 2. A micro motor 506 drives two active gears 504 via a drive rod 505, which in turn drives the rotating rod 502 to rotate the rubber plates 501. This allows the connecting groove 3 and the mounting groove 4 to be closed depending on conditions such as cold or inclement weather, preventing damage to the internal components of the sealing shell 2. When heat dissipation is required, the micro motor 506 adjusts to open the rubber plates 501, allowing air to circulate. With the assistance of a plasma fan bar 507, the air circulates and ions are charged in dust and impurities. Combined with a filter screen 509, the air flows through both sides and is filtered, and a dust collection electrode is also present. 508 can adsorb charged dust and other particles, thus achieving a filtering effect and providing dust prevention while maintaining ventilation and heat dissipation. When dust removal is required, the plasma fan bar 507 is closed, and the micro motor 506 is activated to rotate the rubber plate 501. This rotation, which is in contact with the filter screen 509, generates vibration that causes dust to fall off. At the same time, the rubber plate 501 abuts against the rotating frame 703. The insertion rod 704, which is fixed to the rotating frame 703, passes through the dust collection electrode 508 and is rotatably connected to the sealing shell 2 via the rotating latch 705. Three rotating frames 703 are set up to abut against each other and rotate through transmission, so that the rubber scraper 706 abuts against the dust collection electrode 508 to scrape off the adsorbed dust and other particles, which fall into the collection slot 702 of the insertion frame 701 for unified collection. The insertion frame 701 is fixed to the sealing plate 6, which is convenient for cleaning after the sealing plate 6 is disassembled and installed later. The through hole between the two collection slots 702 inside the insertion frame 701 provides space for gas circulation.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
