[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-12 , the present invention provides a technical solution: a double-layer sealing device for the output shaft of a speed reducer, including a base metal frame 1. The two sides of the top of the base metal frame 1 are symmetrically and fixedly installed with first ground rails 2. A sealing frame 3 is slidably connected to the first ground rails 2. The sealing frame 3 is connected to a first driving assembly 4 arranged on the top of the base metal frame 1. The first driving assembly 4 provides energy for the movement of the sealing frame 3 on the first ground rails 2, and then drives the output shaft to be sealed to move. The movement of the sealing frame 3 on the first ground rails 2 can load the output shaft in a preset area or move to a preset area for the output shaft sealing process;

[0033] At the top of the sealing frame 3, a storage bin 5 is fixedly installed. The storage bin 5 is used to fill sealing oil. At the top of the storage bin 5, several chassis seats 6 are fixedly installed. At the top of the chassis seats 6, a sealing chamber 7 is installed in an embedded and detachable manner. In the middle area at the bottom of the sealing chamber 7, a first intelligent valve 8 is provided. At the top of the storage bin 5, several first pumps 9 are provided. Each first pump 9 is calibrated and correspondingly matched with the first intelligent valve 8 of a sealing chamber 7. The first pump 9 pumps the sealing oil filled in the storage bin 5 into the sealing chamber 7 through the first intelligent valve 8, so that the sealing chamber 7 is filled with sealing oil, and the surface of the output shaft is infiltrated and coated with this sealing oil;

[0034] Several sealing cylinders 10 are fixedly installed in the sealing chamber 7. The top of the sealing cylinder 10 is uncovered, and the sealing cylinder 10 is divided into single cylinders and double cylinders. The single cylinder is used to place one output shaft, and the double cylinder is used to place two output shafts. Single cylinders and double cylinders can be installed simultaneously in the same sealing chamber 7. Several guide holes 11 are sequentially arranged on the side wall of the sealing cylinder 10 from top to bottom. The sealing oil enters the sealing cylinder 10 from the sealing chamber 7 through the guide holes 11, and finally achieves the effect of infiltrating and coating the output shaft;

[0035] Some speed reducers are provided with two output shafts, and the double cylinder is arranged to seal the output shafts of the same specification together;

[0036] On one side of the base metal frame 1, a second ground rail 12 is provided. A transport bin 13 is slidably connected to the second ground rail 12. The transport bin 13 carries sealing oil. The transport bin 13 is connected to a second drive assembly 14 provided at the end of the second ground rail 12. The second drive assembly 14 provides energy for the movement of the transport bin 13 on the second ground rail 12, thereby achieving the purpose that the transport bin 13 can move synchronously with the sealing frame 3, so that the sealing oil is transported during the movement of the sealing frame 3, and the transport speed of the sealing oil and the sealing speed of the output shaft are improved;

[0037] A casing 15 is provided in the transport bin 13. A second pump 16 and a third pump 17 are provided in the casing 15. An extended first conduit 18 is provided on the second pump 16. The first conduit 18 is connected to the side wall of the storage bin 5. The second pump 16 transports the sealing oil in the transport bin 13 into the storage bin 5 through the first conduit 18, and then completes the filling of the sealing oil in the storage bin 5;

[0038] On one side of the base metal frame 1, a base 19 is provided. On the top of the base 19, a telescopic structure 20 is provided. The telescopic structure 20 can be a telescopic rod. At the end of the telescopic structure 20, a first motor 21 is fixedly installed. On the output end of the first motor 21, a first support rod 22 is fixedly installed. The first support rod 22 is a telescopic component. In this embodiment, it can be a telescopic rod. At the end area of the first support rod 22, a support block 24 is fixedly installed. At the bottom of the support block 24, a first electromagnet 23 and a second electromagnet 25 are provided. The electromagnet is a prior art structure, and its function is to adsorb the output shaft;

[0039] The specifications of the first electromagnet 23 and the second electromagnet 25 are the same as those of the sealing cylinder 10. By presetting the PLC program, it can be realized whether to adsorb one output shaft or two output shafts at a time, and then corresponding to a single cylinder and a double cylinder;

[0040] By moving the sealing frame 3 on the first ground rail 2, lifting the telescopic structure 20, and telescoping the first support rod 22, the movement process of the first electromagnet 23 and the second electromagnet 25 is controlled, so that the first electromagnet 23 and the second electromagnet 25 can adsorb all the output shafts in the sealing chamber 7. If one output shaft is adsorbed at a time, only the first electromagnet 23 needs to be driven. If two output shafts are adsorbed at a time, both the first electromagnet 23 and the second electromagnet 25 need to be driven simultaneously. The above realizes the process of adsorbing and fixing the output shaft;

[0041] The up and down movement of the telescopic structure 20 drives the up and down movement of the first motor 21. The up and down movement of the first motor 21 drives the up and down movement of the first support rod 22. The up and down movement of the first support rod 22 drives the up and down movement of the support block 24. The up and down movement of the support block 24 drives the up and down movement of the first electromagnet 23 and the second electromagnet 25. The above process controls the distance between the first electromagnet 23 and the second electromagnet 25 and the sealing chamber 7;

[0042] The operation of the first motor 21 drives the rotation of the first support rod 22. The rotation of the first support rod 22 drives the rotation of the support block 24. The rotation of the support block 24 drives the rotation of the first electromagnet 23 and the second electromagnet 25, and then the angle control of the output shaft adsorbed on the first electromagnet 23 and the second electromagnet 25 can be completed, so that the output shaft can be rotated to different angles;

[0043] At the top of the telescopic structure 20, a first lifting rod 26 is fixedly installed. At the top of the first lifting rod 26, a first connecting rod 27 is fixedly installed. At the end area of the first connecting rod 27, an oil removal chamber 28 is fixedly installed. At the top of the oil removal chamber 28, a second conduit 29 is provided. The second conduit 29 is connected to the third pump 17. The third pump 17 adsorbs the sealing oil in the oil removal chamber 28;

[0044] A first connecting pipe 30 is provided on the inner wall of the oil removal tank 28. The end pipe of the first connecting pipe 30 is connected to the telescopic pipe 31. A scraping plate 32 is provided at the end of the telescopic pipe 31. An internal ring pipe 36 is provided inside the scraping plate 32. The internal ring pipe 36 is connected to the second connecting pipe 33 through a pipe. A suction hole 34 is provided at the end of the second connecting pipe 33. A third connecting pipe 35 is connected to the first connecting pipe 30 through a pipe. The third connecting pipe 35 extends to be connected to the second conduit 29 through a pipe. When the output shaft is moved into the oil removal tank 28, the telescopic pipe 31 starts to operate and drives the scraping plate 32 to descend from the highest position. During the descent of the scraping plate 32, the sealing oil on the surface of the output shaft will be removed. During the descent of the scraping plate 32, the third pump 17 continues to operate. Then, the sealing oil scraped from the surface of the output shaft enters the second connecting pipe 33 through the suction hole 34, then enters the internal ring pipe 36 through the second connecting pipe 33, enters the telescopic pipe 31 through the internal ring pipe 36, enters the first connecting pipe 30 through the telescopic pipe 31, enters the third connecting pipe 35 through the first connecting pipe 30, enters the second conduit 29 through the third connecting pipe 35, and is transported into the transportation tank 13 through the second conduit 29, realizing the reflux recovery of the sealing oil;

[0045] A second support rod 37 is fixedly installed on the side wall of the retractable structure 20. The second support rod 37 is a retractable component. In this embodiment, it can be a telescopic rod. A second connecting rod 48 is fixedly installed at the end of the second support rod 37. A second motor 38 is fixedly installed at the end of the second connecting rod 48. The output end of the second motor 38 is fixedly installed with a side plate 39. The first winding drum 40, the second winding drum 41, the third winding drum 42, and the fourth winding drum 43 are symmetrically arranged at both ends on the side wall surface of the side plate 39. The first winding drum 40 and the second winding drum 41 are a group and wind the sealing film for sealing the upper surface of the output shaft. The third winding drum 42 and the fourth winding drum 43 are a group and wind the sealing film for sealing the lower surface of the output shaft. Among them, the first winding drum 40 and the third winding drum 42 wind the unused sealing film, and the second winding drum 41 and the fourth winding drum 43 wind up the used carrier layer. The sealing film includes a carrier layer and a sealing layer. The sealing layer adheres to the carrier layer. After the sealing layer contacts the surface of the output shaft, it will be adhered by the sealing oil attached to the surface of the output shaft, causing the sealing layer to separate from the carrier layer, and then completing the sealing process of the output shaft through the sealing layer;

[0046] The top and bottom of the side plate 39 are respectively fixedly installed with second lifting rods 44, and the end parts of the second lifting rods 44 are fixedly installed with pressing plates 45. By rotating the first reel 40, the second reel 41, the third reel 42, and the fourth reel 43, the unused sealing layer is moved to the upper and lower sides of the output shaft. Then, the second lifting rod 44 moves to drive the pressing plate 45 to move, and then pushes the sealing film close to the output shaft, so that the sealing layer adheres to the surface of the output shaft. After the sealing layer on the output shaft adheres, the output shaft is placed back into the original sealing cylinder 10. At this time, the surface of the output shaft is attached with sealing oil, and the sealing layer is adhered through the sealing oil. Through the above double sealing method, the sealing performance of the output shaft is improved, ensuring that the output shaft is properly stored during transportation;

[0047] After the output shaft rotates and moves to the position facing the reel through the first support rod 22, then the second support rod 37 moves to drive the entire structure for adhering the sealing layer to move until the output shaft, the first reel 40, the second reel 41, the third reel 42, the fourth reel 43, the second lifting rod 44, and the pressing plate 45 all reach the preset area, and the adhesion of the sealing layer can be carried out;

[0048] A camera assembly 47 is arranged in the middle area of the side wall of the side plate 39. The camera assembly 47 is used to detect whether the sealing layer falls off. If the camera assembly 47 detects that the sealing layer does not fall off from the carrier layer, the output shaft is reset into the sealing cylinder 10, so that the surface of the output shaft is attached with sealing oil again. If the sealing layer still cannot adhere to the output shaft this time, the sealing layer is removed and the next sealing layer is replaced for adhesion until a sealing layer adheres to the surface of the output shaft to ensure the successful sealing of the output shaft;

[0049] A robotic arm 46 is arranged on one side of the base metal frame 1. The function of the robotic arm 46 is to grab the cover plate matching the sealing chamber 7 and embed the cover plate into the top of the sealing chamber 7 to seal the sealing chamber 7.
