As an important component in many devices, the replacement of the seal ring of the sediment cup is particularly important. An automatic seal ring replacement device has been developed under such circumstances.

[0003] This device usually uses a mechanical structure and a control system to work together. First, the position and state of the sediment cup are detected by sensors.

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.

[0024] Referring to Figure 1 and Figure 2 As shown in the figure, an embodiment provided by the present invention: an automatic replacement device for the sediment cup sealing ring, including a workbench 1, a placing table 2 is fixedly connected to the front end of the top of the workbench 1, conveyor belt 2 4 and conveyor belt 1 3 are respectively arranged at the left and right ends of the workbench 1, and the tops of conveyor belt 2 4 and conveyor belt 1 3 are at the same horizontal line as the top of the workbench 1.

[0025] The conveyor belt 1 conveys new sealing rings, and the conveyor belt 2 conveys the old sealing rings away. The sedimentation cup that needs to have its sealing ring replaced is fixed at the top of the placement table 2. The motor 1 is started, and the rotating shaft 1 drives the rotating plate 2 to rotate, so that the directions and positions of the motor 2, the rotating shaft 2, the connecting plate 3, and the electric telescopic rod 4 on the rotating plate 2 are changed, thereby driving the positions and directions of the two external replacement components and the two internal replacement components below to change. Through the cooperation of the two external replacement components with the corresponding electric telescopic rod 4 and motor 2, the sealing ring installed on the outer side of the component to be sealed can be replaced. Through the cooperation of the two internal replacement components with the corresponding electric telescopic rod 4 and motor 2, the sealing ring installed on the inner side of the component to be sealed can be replaced, improving the automation degree and practicality of the sealing ring automatic replacement device, and at the same time solving the problem that the mechanical gripper is sharp and easy to scratch the sealing ring.

[0026] Referring to Figure 2 and Figure 3 , the left-end external replacement component includes a fixing plate 1, at the top of the fixing plate 1 is fixedly connected a spacer sleeve 2, on both the left and right sides of the spacer sleeve 2 are fixedly connected side plates 4, the tops of the two side plates 4 are respectively fixedly connected to the output ends of the adjacent electric telescopic rods 4. At the bottom of the fixing plate 1 are equidistantly provided four chutes 1, inside the spacer sleeve 2 at the top of the fixing plate 1 is fixedly connected a driver 1, the output end of the driver 1 is fixedly connected a connecting shaft 1, at the bottom of the connecting shaft 1 in the upper middle part of the fixing plate 1 is fixedly connected a bevel gear 1, at the outer bottom of the bevel gear 1 are equidistantly meshed four bevel gears 2, in the middle of the four bevel gears 2 are respectively fixedly connected lead screws 1, on the outer sides of the lead screws 1 are threadedly connected sliding rods 1, at the opposite bottom sides of the sliding rods 1 are respectively fixedly connected suction cups 1, on both sides of the adjacent suction cups 1 of the sliding rods 1 are fixedly connected pressing blocks 1, at the top of the spacer sleeve 2 is fixedly connected a vacuum pump 1, the output end of the vacuum pump 1 is fixedly connected a main pipe 1, at the outer bottom of the main pipe 1 are equidistantly communicated four branch pipes 1, the ends of the four branch pipes 1 are respectively communicated with the opposite ends of the suction cups 1, the opposite ends of the lead screws 1 are respectively rotatably connected to the opposite ends of the chutes 1, the tops of the sliding rods 1 slide inside the same-side chutes 1, there is a distance between the bottom of the main pipe 1 and the driver 1, and the side of the pressing block 1 in the central direction of the driver 1 and the opposite side of the suction cup 1 are on the same horizontal line.

[0027] The electric telescopic rod 13 can drive the first fixing plate 14 to move up and down. Start the first driver 16 to make the first connecting shaft 17 drive the first bevel gear 18 to rotate, thereby driving the meshing second bevel gear 19 to rotate. When the second bevel gear 19 rotates, it will drive the first lead screw 20 to rotate. The thread directions of the first lead screws 20 are the same, so that the first sliding rod 21 moves synchronously towards the center of the first fixing plate 14 or synchronously away from the center of the first fixing plate 14 inside the first chute 40, thereby adjusting the distance between the four first suction cups 22. When the adjacent sides of the first suction cups 22 are all in contact with the outer side of the sealing ring, start the first vacuum pump 24 to pump out the air between the first suction cups 22 and the sealing ring, thereby adsorbing the sealing ring. Supplying air between the first suction cups 22 and the sealing ring can make the sealing ring separate from the first suction cups 22. When the first fixing plate 14 rotates, it can drive the first suction cups 22 and the first pressing block 23 to move synchronously. When the first pressing block 23 contacts the sealing ring, the displacement can squeeze the sealing ring so that the sealing ring is located inside the sealing groove.

[0028] Refer to Figure 2 and Figure 4 For the right-end internal replacement component, it includes the second fixing plate 27. The top ends of the second fixing plate 27 are respectively fixedly connected to the output ends of the adjacent electric telescopic rods 13. Four second chutes 41 are equidistantly arranged at the bottom end of the second fixing plate 27. The top end of the second fixing plate 27 is fixedly connected with the second driver 28. The output end of the second driver 28 is fixedly connected with the second connecting shaft 29. The bottom end of the second connecting shaft 29 is fixedly connected with a third bevel gear 30 in the upper middle part of the second fixing plate 27. Four fourth bevel gears 31 are meshed and connected to the outer side of the bottom end of the third bevel gear 30 at equal distances. The middle parts of the four fourth bevel gears 31 are all fixedly connected with second lead screws 32. Second sliding rods 34 are threadedly connected to the outer sides of the second lead screws 32. The bottom ends of the mutually remote sides of the second sliding rods 34 are all fixedly connected with second suction cups 35. Second pressing blocks 36 are fixedly connected to both sides of the adjacent second suction cups 35 of the second sliding rods 34. The bottom end of the second fixing plate 27 is fixedly connected with a second vacuum pump 37. The output end of the second vacuum pump 37 is fixedly connected with a second main pipe 38. Four second branch pipes 39 are communicated with the outer side of the bottom end of the second main pipe 38. The four second branch pipes 39 penetrate through the mutually opposite ends of the second sliding rods 34 and are communicated with the mutually opposite ends of the second suction cups 35. The mutually remote ends of the second lead screws 32 are respectively rotatably connected to the mutually remote ends of the second chutes 41. The top ends of the second sliding rods 34 are slidably connected to the adjacent second chutes 41. The mutually remote sides of the second suction cups 35 and the sides of the second pressing blocks 36 away from the center of the second fixing plate 27 are on the same horizontal line.

[0029] The electric telescopic rod 13 can drive the second fixed plate 27 to move up and down. Start the second driver 28 to make the second connecting shaft 29 drive the third bevel gear 30 to rotate, thereby driving the fourth bevel gear 31 meshing with it to rotate. Since the second lead screw 32 is fixedly connected to the middle of the fourth bevel gear 31, the second lead screw 32 will rotate when the fourth bevel gear 31 rotates. The thread directions of the second lead screws 32 are the same, so that the second slide rod 34 moves synchronously towards the center of the second fixed plate 27 or synchronously away from the center of the second fixed plate 27 inside the second chute 41, thereby adjusting the distance between the four second suction cups 35. When the far sides of the second suction cups 35 are all in contact with the inner side of the sealing ring, by starting the second vacuum pump 37, the air between the second suction cups 35 and the sealing ring can be pumped away, thereby adsorbing the sealing ring. Supplying air between the second suction cups 35 and the sealing ring can make the sealing ring separate from the second suction cups 35. When the second fixed plate 27 rotates, it can drive the second suction cups 35 and the second pressing block 36 to move synchronously. When the second pressing block 36 contacts the sealing ring, the displacement can squeeze the sealing ring so that the sealing ring is located inside the sealing groove.

[0030] Working principle: First, fix the cup body or cup cover of the precipitation cup where the sealing ring needs to be replaced on the placing table 2. If the internal sealing ring needs to be replaced, drive the second fixing plate 27 to move downward through the two electric telescopic rods 13 on the front side, so that the bottom end of the second sliding rod 34 enters the interior. By starting the second driver 28, the away sides of the four second suction cups 35 are made to fit against the inner side of the sealing ring to be replaced. Then, start the second vacuum pump 37 to pump out the air between the second suction cups 35 and the sealing ring, thereby fixing the sealing ring on the away sides of the second suction cups 35. Then, start the second driver 28 to drive the second sliding rod 34 to move the second suction cups 35 relatively, so that the sealing ring is disengaged from the sealing groove. Then, start the corresponding electric telescopic rod 13 to move the sealing ring out of the interior. The four second suction cups 35 on the right side use the same method to adsorb the inner side of the new sealing ring on the first conveyor belt 3. Then, start the first motor 7 to drive the second fixing plate 27 on the front side to rotate to the left, and the second fixing plate 27 on the right side to rotate to the front side. Then, insert the second suction cups 35 adsorbing the new sealing ring into the interior of the precipitation cup, align the outer side of the sealing ring with the sealing groove. Then, start the second driver 28 to make the second suction cups 35 place the new sealing ring into the sealing groove. Then, start the corresponding second motor 10 to drive the second fixing plate 27 to rotate, so that the second pressing block 36 squeezes the new sealing ring in a circle, making the new sealing ring fit tightly against the sealing groove. If the external sealing ring needs to be replaced, move the rear first fixing plate 14 to the front through the first motor 7, and drive the first fixing plate 14 to move downward through the two electric telescopic rods 13 on the front side, so that the position of the first suction cups 22 corresponds to the position of the external old sealing ring. By starting the first driver 16, the adjacent sides of the four first suction cups 22 are made to fit against the outer side of the old sealing ring to be replaced. Then, start the first vacuum pump 24 to pump out the air between the first suction cups 22 and the sealing ring, thereby fixing the sealing ring on the adjacent sides of the first suction cups 22. Then, start the first driver 16 to drive the first sliding rod 21 to move the first suction cups 22 in the reverse direction, so that the sealing ring is disengaged from the external sealing groove. Then, start the corresponding electric telescopic rod 13 to make the sealing ring located at the top of the precipitation cup. The four first suction cups 22 rotated to the right use the same method to adsorb the outer side of the new sealing ring on the first conveyor belt 3. Then, start the first motor 7 to drive the first fixing plate 14 located on the front side to rotate to the left, and the first fixing plate 14 on the right side to rotate to the front side. Then, align the position of the first suction cups 22 adsorbing the new sealing ring with the sealing groove. Then, start the first driver 16 to make the first suction cups 22 place the new sealing ring into the sealing groove. Start the corresponding second motor 10 to drive the first fixing plate 14 to rotate, so that the first pressing block 23 squeezes the new sealing ring in a circle, making the new sealing ring fit tightly against the sealing groove.
