[0030] Embodiment:

[0031] Please refer to Figures 1-4 The embodiment is a kind of sealing ring automatic assembly device 100, it includes sealing ring feeding unit 1, sealing ring taking unit 2 and sealing ring carrying assembly unit 3.

[0032] Sealing ring feeding unit 1 includes vibration disc 11 and the receiving plate 12 of setting in vibration disc 11 output end. Vibration disc 11 exports the sealing ring 200 in vertical standing state to receiving plate 12. The narrow flow channel 121 of vertical is provided in receiving plate 12, the upper of the narrow flow channel 121 is open structure, and sealing ring 200 enters the narrow flow channel 121 in standing state. The end of the narrow flow channel 121 is closed state, and the receiving plate 12 is provided with the take material avoiding groove 122 of horizontal transverse through the narrow flow channel 121 at the last position, so that sealing ring taking unit 2 is taken out into sealing ring 200.

[0033] The seal ring taking unit 2 comprises a first cylinder 21, a first support plate 22 driven by the first cylinder 21 to rotate around a horizontal axis, a second cylinder 23 fixed on the first support plate 22, a second support plate 24 driven by the second cylinder 23 to move up and down or left and right, a third cylinder 25 fixed on the second support plate 24, and a pair of support rods 26 driven by the third cylinder 25 to open or close, which are in the shape of outer eight characters.

[0034] The seal ring taking unit 2 is further provided with a taking auxiliary unit 4 beside the support rods 26, which slightly lifts one side of the seal ring 200 on the support rods 26 to be higher than the other side.

[0035] The seal ring taking unit 2 mainly uses the support rods 26 to extend into the narrow flow channel 121 along the taking avoiding groove 122 to take out one seal ring 200 at the end of the taking plate 12, and then turns over the seal ring 200 to the horizontal state. When the seal ring 200 is turned over to the horizontal state, one side of the body is located above the scraper 42, and the scraper 42 is moved upward to slightly lift the one side of the body, so that one side of the seal ring 200 is high and the other side is low, which facilitates the subsequent seal ring carrying and assembling unit 3 to open and transfer the seal ring.

[0036] The seal ring carrying and assembling unit 3 comprises a motor 31, a third support plate 32 driven by the motor 31 to move horizontally, a fifth cylinder 33 fixed on the third support plate 32, a fourth support plate 34 driven by the fifth cylinder 33 to move up and down, a taking cylinder 35 and a sixth cylinder 36 fixed below the fourth support plate 34, and a pushing ring 37 driven by the sixth cylinder 36 to move up and down outside the taking cylinder 35. The taking cylinder 35 is used to extract the seal ring 200 opened to a certain size, and the bottom of the taking cylinder 35 is upwardly recessed to form an inner hole structure, which is used to accommodate a bearing assembly above the seal ring mounting position, so that the bottom end of the taking cylinder 35 can be directly connected to the seal ring mounting groove on the bearing assembly. The pushing ring 37 is used to push the seal ring 200 sleeved on the outer periphery of the taking cylinder 35 downward to the mounting position to complete the assembly of the seal ring.

[0037] The cooperation process of the seal ring taking unit 2, the seal ring carrying and assembling unit 3, and the taking auxiliary unit 4 is as follows: the support rod 26 takes out a standing seal ring 200 from the narrow flow channel 121, and then turns over 90° to turn the seal ring 200 to the horizontal state; the scraper 42 lifts one side (hereinafter referred to as A side, and the other side is referred to as B side) of the seal ring 200; at this time, there is a height difference space between the A side and the B side, and the taking cylinder 35 moves to the position of the height difference space, such as Figure 4As shown, the right side of the bottom of the taking-out cylinder 35 is matched with the taking-out cylinder 35 to slowly move to the right, the sealing ring A side is wound on the taking-out cylinder 35 and is opened to the right; when the sealing ring is opened to the outer diameter of the taking-out cylinder 35, the supporting rod 26 is withdrawn downward, under the blocking of the scraper 42, the sealing ring 200 cannot move downward with the withdrawal of the supporting rod 26, instead, the B side of the sealing ring 200 is automatically attached to the taking-out cylinder 35, and the extraction of the sealing ring is completed. In the sealing ring extraction process, the opening degree of the sealing ring is greatly reduced, and only slightly larger than the outer diameter of the taking-out cylinder 35 is required, so that the taking-out cylinder 35 can extend into the inner ring area of the sealing ring, and the opening process is opened by the side area of the taking-out cylinder 35. As long as the sealing ring is once opened to be slightly larger than the outer diameter of the taking-out cylinder 35, the sealing ring can be completely transferred to the taking-out cylinder 35 by withdrawing the supporting rod 26 downward, realizing the extraction of the sealing ring, effectively reducing the opening degree of the sealing ring, and meeting the assembly process requirements of the sealing ring.

[0038] The sealing ring carrying and assembling unit 3 moves to the assembling position of the bearing assembly 300 after extracting the sealing ring 200, uses the taking-out cylinder 35 to abut the sealing ring mounting groove on the bearing assembly 300, and then uses the pushing ring sleeve 37 to push the sealing ring 200 on the taking-out cylinder 35 downward to the sealing ring mounting groove, completing the sealing ring assembly.

[0039] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
