The O-ring feeding device 2 is installed on the frame 1 and is used to output O-rings. The valve seat feeding device 3 is installed on the frame 1 and is used to hold valve seats without assembled O-rings. The O-ring assembling device 4 is installed on the frame 1 and is used to assemble O-rings onto the card slots of the valve seats. The O-ring separating device 5 is installed on the frame 1 and is used to transfer the O-rings output by the O-ring feeding device 2 to the O-ring assembling device 4. The robot device 6 is installed on the frame 1 and is used to grab the valve seats on the valve seat feeding device 3 to the O-ring assembling device 4. The valve seat discharging device 7 discharges the valve seats with assembled O-rings by the O-ring assembling device 4, thus completing the entire automatic assembling process of the O-rings.

[0043] In this automatic O-ring assembling machine for faucet valve seats, when assembling the O-rings of the faucet valve seats, workers stack the O-rings onto the O-ring feeding device 2 and place the valve seats on the valve seat feeding device 3 at the same time. The O-ring feeding device 2 outputs the O-rings regularly. The O-ring separating device 5 grabs the regularly output O-rings onto the O-ring assembling device 4. At the same time, the robot device 6 grabs the valve seats to the O-ring assembling device 4. Then the O-ring assembling device 4 assembles the O-rings onto the valve seats. The valve seats with assembled O-rings are discharged by the valve seat discharging device 7, thus completing the entire automatic assembling process of the O-rings. This automatic O-ring assembling machine for faucet valve seats automatically and mechanically assembles O-rings through the O-ring feeding device 2, the valve seat feeding device 3, the O-ring assembling device 4, the O-ring separating device 5, the robot device 6, and the valve seat discharging device 7, avoiding manual assembly, ensuring the assembling quality of the O-rings, and improving the assembling qualification rate. Moreover, during the assembling process, human contact is avoided, ensuring the cleanliness of the valve seats.

[0044] As Figures 2 - 3 shown in the figure, in this embodiment, the O-ring feeding device 2 includes a vibrating bowl 8 and a discharging block 9. The discharging block 9 is installed at the outlet of the vibrating bowl 8. A channel 10 for providing the sliding of a single O-ring is arranged in the discharging block 9. A U-shaped opening 11 is arranged at the bottom of the discharging block 9. In this structure, the vibrating bowl 8 is a common vibrating bowl on the market. The vibrating bowl is used to output the stacked O-rings regularly one by one. Here, the vibrating bowl 8 will not be introduced in detail.

[0045] The specific implementation process of feeding the O-ring by the O-ring feeding device 2 is as follows: The vibrating disk 8 outputs the O-rings regularly to the outlet. The discharging block 9 is vertically arranged at the outlet. There is a channel 10 for providing a single O-ring to slide in the discharging block 9. A U-shaped opening 11 is arranged at the bottom of the discharging block 9. When the O-ring slides to the U-shaped opening 11, the O-ring separating device 5 grabs the O-ring at the U-shaped opening 11 and grabs the O-ring onto the O-ring assembling device 4.

[0046] As Figures 4 - 6 shown, in this embodiment, the valve seat feeding device 3 includes a valve seat mounting frame 12, a valve seat disk 13, a first feeding component 14 and a second feeding component 15.

The second linear module 20 is installed on the valve seat mounting plate 26. The transfer plate 18 is installed at the output end of the second linear module 20. The lifting cylinder 21 is installed on the transfer plate 18. The second feeding plate 19 is installed at the output end of the lifting cylinder 21. The second feeding plate 19 is located above the transfer plate 18 and below the first feeding plate 17.

[0047] The specific implementation process of feeding the valve seat by the valve seat feeding device 3 is as follows: The valve seat disk 13 is used to place the valve seats without O-rings installed. The first feeding component 14 and the second feeding component 15 are arranged overlappingly. The first feeding component 14 includes a first linear module 16 and a first feeding plate 17. The first linear module 16 is installed on the valve seat mounting frame 12. The first feeding plate 17 is installed at the output end of the first linear module 16, realizing the movement of the first feeding plate 17 on the valve seat mounting frame 12. When the valve seats on the first feeding component 14 are taken out, move it to one side of the valve seat mounting frame 12. At this time, since the second linear module 20 is installed on the valve seat mounting plate 26, the transfer plate 18 is installed at the output end of the second linear module 20, the lifting cylinder 21 is installed on the transfer plate 18, the second feeding plate 19 is installed at the output end of the lifting cylinder 21, the second feeding plate 19 is located above the transfer plate 18 and below the first feeding plate 17, move the transfer plate 18 to stagger it from the first feeding plate, start the lifting cylinder 21 to lift the second feeding plate 19 to the same horizontal plane as the first feeding plate, then grab the valve seats on the first feeding component 14. After taking them out, lower the second feeding plate and then grab the valve seats replenished on the first feeding component 14, thus realizing automatic and continuous feeding, greatly improving the valve seat assembly efficiency.

[0048] AsFigure 6 As shown, in this embodiment, the second feeding component 15 further includes a plurality of guiding mechanisms. The guiding mechanism includes a guiding block 22 and a guiding rod 23. A guiding hole is provided on the transfer plate 18, and a through hole communicating with the guiding hole is provided on the guiding block 22. One end of the guiding rod 23 is fixed on the second feeding plate 19, and the other end of the guiding rod 23 passes through the through hole and the guiding hole and extends below the transfer plate. In this structure, one end of the guiding rod 23 is fixed on the second feeding plate 19, and the other end of the guiding rod 23 passes through the through hole and the guiding hole and extends below the transfer plate, playing a guiding role when the second feeding plate 19 is lifted or lowered.

[0049] As Figures 7 - 9As shown, in this embodiment, the O-ring assembly device 4 includes an assembly mounting base 24, an assembly mounting frame 25, a valve seat mounting plate 26, a first lifting assembly 27, and an expansion assembly 28; the assembly mounting base 24 is installed on the frame 1, a slide rail 44 is provided on the assembly mounting base 24, a slider 45 is provided at the bottom of the assembly mounting frame 25, and the slider 45 is slidably connected to the slide rail 44; a number of support rods 29 are provided on the assembly mounting frame 25, the valve seat mounting plate 26 is fixed to the support rods 29, and a valve seat hole 30 for passing through the valve seat mounting plate 26 is provided on the valve seat mounting plate 26; the expansion assembly 28 includes an X-axis expansion mechanism 31 and a Y-axis expansion mechanism 32, the X-axis expansion mechanism 31 includes an X-axis double-acting cylinder 33, two X-axis connecting plates 34, and two X-axis expansion blocks 87, the X-axis double-acting cylinder 33 is installed on the assembly mounting frame 25, the two X-axis connecting plates 34 are respectively installed at the two output ends of the X-axis double-acting cylinder 33, and the two X-axis expansion blocks 87 are respectively installed on the two X-axis connecting plates 34; the Y-axis expansion mechanism 32 includes a Y-axis mounting seat 35, a Y-axis double-acting cylinder 36, two Y-axis connecting plates 37, and two Y-axis expansion blocks 38, the Y-axis mounting seat 35 is installed on the assembly mounting frame 25, the Y-axis double-acting cylinder 36 is installed on the Y-axis mounting seat 35, the two Y-axis connecting plates 37 are respectively installed at the two output ends of the Y-axis double-acting cylinder 36, and the two Y-axis expansion blocks 38 are respectively installed on the two Y-axis connecting plates 37; the first lifting assembly 27 includes a first lifting cylinder 39, a connecting plate, an O-ring mounting plate 40, and two lifting rods 41, the first lifting cylinder 39 is installed on the assembly mounting frame 25, the connecting plate is installed at the output end of the first lifting cylinder 39, one ends of the two lifting rods 41 are respectively fixed to both ends of the connecting plate, the other ends of the lifting rods 41 pass through the assembly mounting frame 25 and extend to the lower side of the valve seat mounting plate 26, the O-ring mounting plate 40 is fixed to the two lifting rods 41, and the O-ring mounting plate 40 is provided with an X-axis moving slot 42 and a Y-axis moving slot 43, and the X-axis expansion block 87 can move along the X-axis moving slot 42, and the Y-axis expansion block 38 can move along the Y-axis moving slot 43.

[0050] The specific process of the O-ring assembling device 4 for assembling the O-ring is as follows: The O-ring separating device 5 grabs the O-ring from the discharge port U-shaped opening 11 of the O-ring feeding device 2, passes through the valve seat hole 30 on the valve seat mounting plate 26 and places it on the O-ring mounting plate 40, and makes the two X-axis expansion blocks 87 and the two Y-axis expansion blocks 38 located inside the O-ring. The two X-axis expansion blocks 87 and the two Y-axis expansion blocks 38 are driven by the X-axis double-acting cylinder 33 and the Y-axis double-acting cylinder 36 to move outward along the X-axis moving groove 42 and the Y-axis moving groove 43 respectively to expand the O-ring. At the same time, the robot device 6 grabs the valve seat from the valve seat feeding device 3 to the valve seat mounting plate 26, aligns it with the valve seat hole 30 and moves it downward to the upper part of the O-ring. At this time, the first lifting cylinder 39 of the first lifting assembly 27 is started, and the first lifting cylinder 39 jacks up the O-ring mounting plate 40 upward. Since the O-ring is placed on the O-ring mounting plate 40, the O-ring mounting plate 40 moves the O-ring upward. During the upward movement of the O-ring, the O-ring disengages from the X-axis expansion block 87 and the Y-axis expansion block 38, and the valve seat is located above the O-ring. The O-ring disengaged from the X-axis expansion block 87 and the Y-axis expansion block 38 just falls into the clamping groove of the valve seat, thus realizing the automatic assembly of the valve seat and the O-ring.

[0051] As Figure 10 shown, in this embodiment, the O-ring separating device 5 includes a separating bracket 46, a separating mounting plate 47, a first rotating assembly 48, a translation assembly 49 and a grasping assembly 50; the separating bracket 46 is installed on the frame 1, and the separating mounting plate 47 is slidably connected to the separating bracket 46; the first rotating assembly 48 includes a first rotating cylinder 51 and a rotating plate 53, the first rotating cylinder 51 is installed on the separating mounting plate 47, and the rotating plate 53 is installed on the output end of the first rotating cylinder 51; the translation assembly 49 includes a translation cylinder 54 and a translation plate 55, the translation cylinder 54 is installed on the rotating plate 53, and the translation plate 55 is installed on the output end of the translation cylinder 54; the grasping assembly 50 includes a grasping cylinder 56 and a gripper 57, the grasping cylinder 56 is installed on the translation cylinder 54, and the gripper 57 is installed on the output end of the grasping cylinder 56.

[0052] The specific implementation process of the O-ring separation device 5 is as follows: Since the translation cylinder 54 is installed on the rotating plate 53 and the grasping cylinder 56 is installed on the translation cylinder 54, when grasping the O-ring, the first rotating cylinder 51 rotates the grasping cylinder 56 to the horizontal state, that is, the gripper 57 is in the horizontal state. The gripper 57 specifically includes two oppositely arranged expansion blocks. Start the translation cylinder 54 to align the gripper 57 with the vertically arranged O-ring and move the gripper 57 into the O-ring. Start the gripper 57 cylinder, and the gripper 57 expands to clamp the O-ring tightly. Then, the translation cylinder 54 moves the O-ring above the valve seat mounting plate 26. Rotate the first rotating cylinder 51 to rotate the grasping cylinder 56 to the vertical state. At this time, the O-ring is in the horizontal state. The translation cylinder 54 then moves the O-ring downward to the O-ring mounting plate 40 and aligns it with the X-axis expansion block 87 and the Y-axis expansion block 38. The gripper 57 cylinder contracts, and the O-ring disengages from the gripper 57 and falls onto the O-ring mounting plate 40, and the X-axis expansion block 87 and the Y-axis expansion block 38 are located inside the O-ring, thus realizing the automatic separation and feeding of the O-ring.

The gripper cylinder 60 is installed at the output end of the mobile robot 58, and both the clamping block 61 and the stopper 62 are installed at the output end of the gripper cylinder 60. In this structure, the mobile robot 58 is a standard robot and will not be elaborated here.

[0054] The specific implementation process of the robot device 6 for grasping the valve seat is as follows: Start the mobile robot 58, align the robot gripper 59 with the valve seat on the valve seat feeding device 3, start the gripper cylinder 60, the clamping block 61 and the stopper 62 open and align with the valve seat. The mobile robot 58 continues to move the robot gripper 59 downward so that the valve seat is located between the block and the stopper 62. Then, contract the gripper cylinder 60, the stopper 62 blocks one side of the valve seat, the clamping block 61 clamps the valve seat tightly, and the mobile robot 58 moves the grasped valve seat above the valve seat mounting plate 26 and aligns it with the valve seat hole 30.
