[0002] Sealing rings are suitable for installation on various mechanical equipment to seal at a specified temperature, pressure, and in different liquid and gas media, in a static or moving state. Various types of sealing rings are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, engineering machinery, construction machinery, and various instruments and meters.

[0003] When installing sealing rings on various equipment, a sealing ring discharging device is required. However, the existing sealing ring discharging device does not detect the front and back states of the sealing ring when discharging. This will not have an impact on some sealing rings that do not need to distinguish between the front and back sides. However, for sealing rings with front and back sides, the sealing rings need to face a specified direction during assembly, which requires that the front and back states of the sealing rings transported to the assembly equipment are all consistent. The prior art usually uses manual labor or adds multiple sets of equipment to detect the direction of the sealing ring, which undoubtedly increases the production cost and time. For devices that require continuous, uninterrupted, efficient and fast discharging, this limitation is obviously disadvantageous. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 8 The utility model is further described in detail:

[0024] The utility model discloses a device for discharging and detecting the front and back of a sealing ring, such as Figure 1 , Figure 2 , Figure 3As shown, a device for discharging and positive and negative detection of a sealing ring of the utility model comprises a sealing ring barrel 1, a discharging port 11 is provided at the bottom of the sealing ring barrel 1, and also comprises a mounting base plate 12, a swing cylinder 13 and a sealing ring detection device; an upper opening of the sealing ring barrel 1 is detachably connected with an upper cover 3, a compressed air interface 4 is fixedly installed on the top of the upper cover 3, a stirring lever 5 is rotatably connected to the bottom of the sealing ring barrel 1, a swing cylinder 13 for rotating the stirring lever 5 is fixedly installed at the bottom of the sealing ring barrel 1 by bolts, a mounting base plate 12 is fixedly connected at the bottom of the swing cylinder 13 by bolts, and a sealing ring detection device for detecting the direction of the sealing ring is fixedly installed on the side wall of the mounting base plate 12 by bolts; a discharging assembly 6 cooperating with the sealing ring detection device is provided on the outer wall of the discharging port 11; in this embodiment, the position of the discharging port 11 is as shown in FIG. Figure 2 As shown, the mounting base plate 12 can be used to mount the entire device on a wall or operating table by bolts. Figure 3 As shown, both ends of the stirring lever 5 are arc-shaped surfaces, and the output end of the swing cylinder 13 passes through the bottom of the sealing ring barrel 1 and is connected to the stirring lever 5. The stirring lever 5 can be rotated inside the sealing ring barrel 1 through the swing cylinder 13, and then with the compressed air entering from the compressed air interface 4, a positive pressure can be formed in the barrel, and the sealing ring is pushed out from the discharge port 11 into the discharge assembly 6. It is worth noting that the height of the discharge port 11 should be slightly larger than the height of the sealing ring rubber body to ensure that only one sealing ring passes through each time. By setting up the compressed air interface 4 and the swing cylinder 13, the sealing ring can be automatically discharged continuously and quickly; by setting up a sealing ring detection device, the front and back of the sealing ring can be detected to prevent the sealing ring from being installed incorrectly, thereby improving the yield rate.

[0025] like Figure 1 , Figure 4As shown, the sealing ring detection device includes a detection arm 21, a detection cylinder 22, an elastic connecting rod 23, a metal proximity switch 24 and a conical detection fixture 25; the side wall of the mounting base 12 is fixedly connected with a first mounting plate 26 by bolts, the side wall of the first mounting plate 26 is fixedly installed with a detection cylinder 22 by bolts, the output end of the detection cylinder 22 is fixedly connected with the detection arm 21 by bolts, the top of the detection arm 21 is fixedly installed with a metal proximity switch 24, the bottom of the detection arm 21 is fixedly installed with one end of the elastic connecting rod 23, and the elastic connecting rod 23 is fixedly installed with the metal proximity switch 24. The other end is fixedly connected with a conical detection fixture 25; in the present embodiment, the conical detection fixture 25 can be used to detect the direction of the sealing ring. When in use, the detection cylinder 22 will drive the detection arm 21 to move up and down, so that the conical detection fixture 25 at the end of the elastic connecting rod 23 can enter the center hole of the sealing ring in the discharge assembly 6. Since the sealing ring has two sides, the depth of the conical detection fixture 25 in the center hole of the sealing ring will be different, so that it can be detected by the metal proximity switch 24 to determine the direction of the sealing ring.

[0026] like Figure 4 , Figure 5 , Figure 6 As shown, the elastic connecting rod 23 includes a connecting rod seat 231 and an elastic rod 232; a through hole 233 is opened at the top of the detection arm 21, and the bottom of the detection arm 21 is fixedly connected to the connecting rod seat 231, and the elastic rod 232 is slidably connected inside the connecting rod seat 231. One end of the elastic rod 232 is fixedly connected to the conical detection fixture 25, and the other end of the elastic rod 232 passes through the through hole 233 and can enter the detection area of ​​the metal proximity switch 24; in this embodiment, the specific structure of the connecting rod seat 231 and the elastic rod 232 is as follows Figure 5 , Figure 6 As shown, the elastic rod 232 can slide in the connecting rod seat 231. During the detection, as the conical detection fixture 25 enters the center hole of the sealing ring, the end of the elastic rod 232 will pass through the through hole 233 at the top of the detection arm 21 to reach the detection area of ​​the metal proximity switch 24. After the detection is completed, when the detection cylinder 22 lifts the detection arm 21, the elastic rod 232 will automatically return to the previous position in the connecting rod seat 231 under the action of elasticity. It is worth noting that although the distance of the conical detection fixture 25 in the sealing ring is different when the sealing ring is in different directions, the difference caused by this distance is very small. Since the metal proximity switch 24 can only produce two detection results, namely: sensing the elastic rod 232 and not sensing the elastic rod 232, therefore, in this embodiment, it is necessary to strictly set the lifting distance of the detection cylinder 22, so as to strictly control the position state of the conical detection fixture 25 in the sealing ring in different directions.

[0027] like Figure 1 , Figure 2 , Figure 7As shown, the discharge assembly 6 includes a discharge base 61, a discharge cover plate 62 and a lifting cylinder 66; the outer wall of the discharge port 11 is fixedly connected to the discharge base 61 by bolts, the top of the discharge base 61 is provided with a discharge slide 63 for the sealing ring to pass through, the top of the discharge base 61 is fixedly connected to the discharge cover plate 62 by bolts, and the top of the discharge cover plate 62 is provided with a detection hole 64 for the conical detection fixture 25 to pass through; the side wall of the mounting base 12 is fixedly connected to the second mounting plate 65 by bolts, and the side wall of the second mounting plate 65 is fixedly installed with a lifting cylinder 66 by bolts, and the lifting cylinder The output end of 66 is fixedly connected by bolts with a limit plate 67 for limiting the sealing ring that reaches the lower side of the detection hole 64; in this embodiment, the limit plate 67 is arranged at the outlet of the discharge chute 63, so that the sealing ring entering the discharge chute 63 is blocked by the limit plate 67, and the sealing ring is just below the detection hole 64 at this time, so that the conical detection fixture 25 can just enter the center hole of the sealing ring. After the conical detection fixture 25 completes the detection of the sealing ring, the lifting cylinder 66 will lower the limit plate 67, and the sealing ring can be taken out from the discharge base 61 by the mechanical arm. It is worth noting that a contact sensor (not released in the figure) can be arranged inside the limit plate 67. When the sealing ring reaches the limit plate 67, it can be sensed by the limit plate 67 to cooperate with the sealing ring detection device for detection. At the same time, the coordination between the limit plate 67 and the sealing ring detection device can also be controlled by optical fiber sensors and manual operation.

[0028] like Figure 1 , Figure 2 , Figure 8 As shown, a threaded hole 14 is provided on the side wall of the upper opening of the sealing ring barrel 1, a bolt is connected to the threaded hole 14, and a slide groove 31 matching the bolt is provided on the side wall of the upper cover 3; in this embodiment, the specific structure of the upper cover 3 is as shown in Figure 8 As shown, a bolt (not shown) is threadedly connected to the threaded hole 14. The upper cover 3 can be quickly fixed to the upper opening of the sealing ring barrel 1 through the cooperation of the slide groove 31 and the bolt. Preferably, a handle 32 is fixed to the top of the upper cover 3 by bolts.

[0029] The implementation principle of the embodiment of the utility model is:

[0030] First, pour a large amount of bulk sealing ring material into the sealing ring barrel 1, start the swing cylinder 13, and the stirring lever 5 will stir the sealing ring in the barrel. The sealing ring close to the bottom will continue to move, and the stirring lever 5 will gently press the sealing ring into the discharge port 11. The sealing ring barrel 1 is connected to compressed air through the compressed air interface 4 at the top, and positive pressure is formed in the sealing ring barrel 1. As long as the sealing ring slightly enters the discharge port 11, it will enter the discharge chute 63 of the discharge base 61 through the discharge port 11 under the action of positive pressure to realize single-circle material collection;

[0031] Secondly, after the sealing ring reaches the discharge base 61, it is blocked by the limit plate 67, and the detection cylinder 22 starts to press down, and the conical detection fixture 25 at the end of the elastic connecting rod 23 is pressed into the center hole of the sealing ring. Since the sealing ring conical detection fixture 25 of different directions enters to different depths, the lifting height position of the upper end of the elastic connecting rod 23 is also at different heights. The direction of the sealing ring is determined based on whether the metal proximity switch 24 can sense the signal at the top of the elastic connecting rod 23;

[0032] Finally, after the detection is completed, the detection cylinder 22 is started and lifted, the lifting cylinder 66 is started to lower the limit plate 67, and the mechanical arm takes the sealing ring out of the discharge base 61; the above operation can be repeated to complete the discharge and detection of the sealing ring.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
