[0045] The present invention will be further described below with reference to the accompanying drawings.

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0047] On the contrary, the present invention covers any alternatives, modifications, equivalent methods and solutions made within the spirit and scope of the present invention defined by the claims. Further, in order to enable the public to have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these details.

[0048] As Figures 1 to 3 shown, a fully automatic faucet valve core assembly machine includes a frame 6. A turntable 7 is arranged on the frame 6. Along the circumferential side of the turntable 7, a valve sleeve feeding station 1, a rubber gasket assembly station 2, a rubber gasket compaction station 3, a core body assembly station 4, and a valve core unloading station 5 are sequentially distributed.

[0049] As Figure 1 、 Figure 4 shown, on the frame 6, a cam intermittent dividing mechanism 72 is arranged below the turntable 7. The cam intermittent dividing mechanism 72 is connected to a motor 71 through a synchronous belt 73. The cam intermittent dividing mechanism 72 is arranged at the lower end of the turntable 7, and the rotating shaft of the cam intermittent dividing mechanism 72 is connected to the turntable 7. The cam intermittent dividing mechanism 72 controls the turntable 7 to rotate at a set angle, ensuring that the loading plate 8 passes through the above stations in sequence.

[0050] As Figure 4 and Figure 5 shown, a plurality of loading plates 8 are arranged on the turntable 7. The loading plates 8 are evenly distributed on the circumferential side of the turntable 7. One end of the loading plate 8 is fixed to the turntable 7 by screws, and the other end extends out of the turntable 7. And an installation hole is arranged in the vertical direction at the end of the loading plate 8 extending out of the turntable 7. A sleeve 81 is arranged in the installation hole. The lower end of the sleeve 81 passes through the installation hole and is connected to a driving gear 82. The inner circle of the sleeve 81 is matched with the shape of the valve sleeve. The shape shown in the present invention is hexagonal.

[0051] The material loading plate 8 includes a first sheet body and a second sheet body. The first sheet body and the second sheet body are fixed by bolts. The mounting holes penetrate through the first sheet body and the second sheet body. Limiting bearings 83 are arranged in the mounting holes of the first sheet body and the second sheet body. A limiting convex block 81a is arranged on the circumferential side of the sleeve 81. After installation, the two limiting bearings 83 are respectively located at both ends of the limiting convex block 81a, restricting the sleeve 81 from disengaging from the mounting hole in the vertical direction and not affecting the rotation of the sleeve 81. First grooves are respectively arranged on the opposite sides of the first sheet body and the second sheet body. Second grooves are arranged at the bottoms of the two first grooves. A positioning rod 84 is arranged in the first groove. One end of the positioning rod 84 is in contact with the limiting convex block 81a. The other end of the positioning rod 84 extends out of the material loading plate 8. A second return spring 85 fixed in the second groove is sleeved on the positioning rod 84.

[0052] As Figure 1 , Figure 6 and Figure 7 shown, the valve sleeve loading station 1 mainly includes a first support 13. A first slide plate 14 and a first linear feeder 19 are arranged on the first support 13. The first slide plate 14 is vertically erected on one side of the first linear feeder 19. The first slide plate 14 is slidably fitted on the first support 13 through a slide rail. A loading manipulator 15 and a first vertical cylinder 12 are installed on the first slide plate 14. The first vertical cylinder 12 can drive the loading manipulator 15 to move up and down. A first horizontal cylinder 11 is installed on the first support 13. The piston rod of the first horizontal cylinder 11 is connected to the first slide plate 14. The first horizontal cylinder 11 drives the entire first slide plate 14 and the components thereon to move horizontally.

[0053] As Figure 5 , Figure 6 , Figure 7 , Figure 8 shown, a transverse moving block 17 is arranged at the discharging end of the first linear feeder 19 and is driven to move horizontally by a first pushing cylinder 18 arranged below the first linear feeder 19. A clamping notch 17a is arranged on the side of the transverse moving block 17 facing the first linear feeder 19. Its width only allows one valve sleeve to enter. The transverse moving block 17 is integrally in a concave structure. An upper limiting block 16 is arranged on the upper side of the transverse moving block 17 to restrict the transverse moving block 17 from moving below the first linear feeder 19 and the loading manipulator 15. On the other side of the transverse moving block 17 is a turntable 7. After the loading manipulator 15 clamps the valve sleeve 91 downward, takes out the valve sleeve from the clamping notch 17a of the transverse moving block 17 upward, horizontally transfers it above the in-place material loading plate 8, and then puts it into the sleeve 81 of the material loading plate 8 downward.

[0054] As Figure 1 , Figure 9 , Figure 10 , Figure 11As shown in the figure, the rubber pad assembly station 2 includes a second support 23. A second linear feeder 26 and a second slide plate 24 are arranged on the second support 23. The second slide plate 24 is vertically arranged on one side of the second linear feeder 26. The second slide plate 24 is arranged on the second support 23 through a slide rail. A second vertical cylinder 22 is installed on the second slide plate 24. The piston rod of the second vertical cylinder 22 is connected with a mounting block 210. A plug 29 is fixed on the lower end face of the mounting block 210. A pressing cylinder 27 is arranged vertically above the mounting block 210. The inner diameter of the pressing cylinder 27 is larger than the diameter of the plug 29. The pressing cylinder 27 and the plug 29 are coaxially arranged. A first return spring 28 is arranged inside the pressing cylinder 27. The lower end of the first return spring 28 supports on the mounting block 210, and the upper end abuts against the top end of the pressing cylinder 27, so that the upper part of the pressing cylinder 27 protrudes above the mounting block 210. The lower end of the pressing cylinder 27 is limited on the mounting block 210 to prevent the pressing cylinder 27 from disengaging from the mounting block 210. A first downward pressing cylinder 25 is further arranged above the valve sleeve. The first downward pressing cylinder 25 is arranged on the frame 6.

[0055] In this embodiment, a notch is arranged on the side wall of the pressing cylinder 27 for assembling with the mounting block 210. The second transverse cylinder 21 drives the second slide plate 24 and the components on the second slide plate 24 to move horizontally together. The second vertical cylinder 22 drives the mounting block 210 to move up and down. Initially, the mounting block 210 first moves towards the discharge end direction of the second linear feeder 26, and the plug 29 is used to insert into the inner hole of the rubber gasket to fix the rubber gasket on the plug 29. Then the mounting block 210 moves up, is horizontally transported above the loading plate 8, and then moves down to be close to the top end of the valve sleeve. At this time, the first downward pressing cylinder 25 presses the pressing cylinder 27 downward. The pressing cylinder 27 overcomes the elastic force of the first return spring 28, passes through the mounting block 210 and abuts against the outer edge of the upper surface of the rubber gasket, so that the rubber gasket is separated from the plug 29 and is squeezed into the sealing groove at the top of the valve sleeve, and then each mechanism retracts.

[0056] Among them, the first downward pressing cylinder 25 can be fixed on the second slide plate 24 or can be separately fixed on the frame and is always placed above the corresponding loading plate 8. A support cylinder 211 is arranged below the loading plate 8. The cylinder body of the support cylinder 211 is fixed on the frame 6. When the first downward pressing cylinder 25 presses downward, the support cylinder 211 supports upward on the bottom surface of the loading plate 8, which can prevent the downward pressure of the first downward pressing cylinder 25 from being too large and causing damage to the loading plate 8.

[0057] Such as Figure 1 、 Figure 5 、 Figure 12 、 Figure 13 、 Figure 15As shown in the figure, the rubber pad compaction station 3 is arranged between the rubber pad assembly station 2 and the core assembly station 4, and includes the third bracket 33, the lower radial cylinder 31, the upper radial cylinder 32, the third slide plate 34, the pressure plate 35, the first driving gear 36, and the support plate 37. The third slide plate 34 is slidably arranged on the third bracket 33 through a slide rail. The lower radial cylinder 31 is connected to one end of the third slide plate 34 facing away from the loading plate 8, the upper radial cylinder 32 and the support plate 37 are installed on the third slide plate 34, and the upper radial cylinder 32 is connected to one end of the support plate 37 facing away from the loading plate 8. The support plate 37 is rotatably connected with a pressure plate 35 at one end opposite to the loading plate 8. The pressure plate 35 is cylindrical, and its bottom surface is arranged as an arc surface. The first driving gear 36 is arranged at the front end of the third slide plate 34, and a motor (hidden in the third bracket 33 and not shown in the figure) for driving the first driving gear 36 to rotate is arranged below the third slide plate 34. Initially, the lower radial cylinder 31 drives the slider to move radially towards the loading plate 8 until the first driving gear 36 meshes with the transmission gear 82 on the lower surface of the material plate; the upper radial cylinder 32 drives the pressure plate 35 to move towards the rubber gasket on the top of the valve sleeve through the support plate 37 until the lower surface of the pressure plate 35 abuts against the circumferential side surface of the rubber gasket and applies a downward pressure to it. The motor drives the first driving gear 36 to rotate, so that the sleeve 81 drives the entire valve sleeve 91 to rotate, realizing the compaction of the rubber gasket 92 and preventing the rubber gasket 92 from warping.

[0058] As Figure 1 , Figure 2 , Figure 14 , Figure 15 shown, the core assembly station 4 includes the fourth bracket 410. A radial cylinder four 411 and a fourth slide plate 49 are arranged on the fourth bracket 410. The radial cylinder four 411 is connected to one end of the fourth slide plate 49 facing away from the turntable 7. On the fourth slide plate 49, a second driving gear 48 is arranged. The second driving gear 48 is rotatably arranged at the front end of the fourth slide plate 49, and a driving motor 416 for driving the second driving gear 48 to rotate is arranged at the bottom of the fourth slide plate 49. An installation frame 47 is also arranged at the front end of the fourth slide plate 49. A second pressing cylinder 45 is installed at the top of the installation frame 47, and a pressing rod 46 is connected to the piston rod of the second pressing cylinder 45.

[0059] The core transmission device includes a vibrating disk three (not shown in the figure) and a support frame 414. The vibrating disk three is connected with a vertically arranged core transmission pipeline 44. The core transmission pipeline 44 is arranged on the support frame 414. Upper limit cylinders 42 and lower limit cylinders 43 are respectively arranged at both ends of the core transmission pipeline 44. The piston rods of the upper limit cylinders 42 and the lower limit cylinders 43 extend into the core transmission pipeline 44 to ensure that only one core falls out at a time.

[0060] As Figure 4 , Figure 14 , Figure 15As shown, the core support platform 413 is arranged below the core transfer pipeline 44. The core support platform 413 is connected to the second push cylinder 41 to achieve lateral movement. The second push cylinder 41 is fixed on the support frame 414. A through hole is arranged in the core support platform 413 in the vertical direction. A core support lifting rod 415 is arranged in the through hole. A lifting cylinder 412 is arranged at the bottom of the core support lifting rod 415. The cylinder block of the lifting cylinder 412 is fixed on the core support platform 413. A notch is arranged on the top surface of the core support lifting rod 415 for fitting the bottom of the core. When the core support lifting rod 415 is in the initial position, it is coaxial with the core transfer pipeline 44. The core vertically falls onto the core support lifting rod 415 through the core transfer pipeline 44 and is laterally driven by the core support platform 413 to be transferred below the loading plate 8. The fourth radial cylinder 411 drives the second driving gear 48 to move radially and engage with the transmission gear 82. The lifting cylinder 412 jacks up the core upward so that the core is aligned with the threaded hole at the tail of the core docking valve sleeve 91. Then, the second pressing cylinder 45 drives the pressing rod 46 to press down the valve sleeve 91 to ensure the axial position of the valve sleeve 91 is fixed. Then, the driving motor 416 drives the second driving gear 48 to rotate, driving the valve sleeve 91 to rotate, and gradually screwing the core into the threaded hole of the valve sleeve 91.

[0061] As Figure 1 , Figure 16 , Figure 17 shown, the valve core blanking station 5 includes a fifth bracket 53. A valve core blanking track 56 is arranged on the fifth bracket 53. The valve core blanking track 56 is inclined to facilitate material falling. A fifth slide plate 54 is arranged on the fifth bracket 53. The back of the fifth slide plate 54 is connected to a horizontal cylinder 51. The horizontal cylinder 51 is arranged on the fifth bracket 53. A third vertical cylinder 52 is arranged on the surface of the fifth slide plate 54. The piston rod of the third vertical cylinder 52 is connected to an oil blanking manipulator 55. The blanking manipulator 55 clamps the assembled valve core from the loading plate 8 and places it into the valve core blanking track 56.

[0062] Among them, both the loading manipulator 15 and the blanking manipulator 55 are preferably of pneumatic gripper structure. The working surface of the gripper is set as an arc to adapt to the top contour of the valve sleeve 91.
