It should be noted that when the body vibration plate 8 vibrates and distributes the body 1 and transmits it through the body 1 transmission pipeline into the second body material discharge hole 26 on the second feeder of the body 1, the installation cavity opening 70 of the body 1 faces directly upward.

[0048] like Figure 7 As shown, the round plug placement mechanism includes a round plug vibration disk 10 and a round plug distribution mechanism 11; the round plug distribution mechanism 11 includes a first round plug positioning member 27, a second round plug positioning member 28 and a fifteenth driving device 29; one end of the first round plug positioning member 27 is placed directly above the fixture 7 and is provided with a first round plug discharge hole 30 adapted to the round plug 2; one end of the second round plug positioning member 28 is provided with a second round plug discharge hole adapted to the round plug 2; a round plug 2 transmission pipeline connected to the second discharge hole of the round plug 2 is provided on the round plug vibration disk 10; the fifteenth driving device 29 is used to drive the second round plug positioning member 28 to move on the upper end surface of the first round plug positioning member 27, so that the second discharge hole of the round plug 2 can coincide with the first discharge port of the round plug 2, thereby realizing the discharge of the round plug 2 into the installation cavity of the main body 1 directly below.

[0049] like Figure 8 As shown, at the upstream station of the round plug placement mechanism, a body 1 detection mechanism for detecting whether the installation cavity opening 70 is facing upward is also provided; it includes a detection needle 32 and a first driving device 33 for driving the detection needle 32 to move in the vertical direction; the diameter of the detection needle 32 is smaller than the diameter of the installation cavity opening 70, and smaller than the diameter of the other end opening opposite to the installation cavity opening 70. When the installation cavity opening 70 of the body 1 is not facing upward, the detection needle 32 cannot be inserted into the installation cavity of the body 1.

[0051] In this embodiment, if Figures 11 to 14 As shown, the first positioning assembly 15 includes a third positioning member 40 having a first positioning groove 39 for placing the body 1, a first servo motor 41 for driving the third positioning member 40 to flip, and a second servo motor 42 for driving the third positioning member 40 to move in the vertical direction; the second positioning assembly 16 includes a fourth positioning member 45 having a second positioning groove 49 for placing the rubber sleeve 5 and the flow limiter 4, and a third servo motor 46 for driving the fourth positioning member 45 to flip, and a fourth servo motor 47 for driving the fourth positioning member 45 to move closer to or away from the third positioning member 40; a positioning pin 48 is provided at the axis of the second positioning groove 49. The positioning pin 48 is used to realize the preliminary assembly positioning of the rubber sleeve 5 and the flow limiter 4, so that the flow limiter 4 can be assembled synchronously when the rubber sleeve 5 is pressed with the body 1. At the same time, the positioning pin 48 also prevents the rubber sleeve 5 and the flow limiter 4 from falling off when the fourth positioning member 45 is flipped.

[0052] like Fig.15 As shown, the first transfer mechanism 14 includes a first mechanical gripper 50, a fifth driving device 51 for driving the first mechanical gripper 50 to move, a sixth driving device 52 for driving the first mechanical gripper to move in a vertical direction, and a seventh driving device 53 for driving the first mechanical gripper to move in a horizontal direction. The first mechanical gripper 50 grabs the body 1 assembled with the spring 3 from the jig 7 on the turntable 6 and transfers it to the first positioning groove 39 of the third positioning member 40, and the first positioning groove 39 is opened upward.

[0053] like Fig.16 and Fig.17 As shown, the rubber sleeve distributing mechanism 18 includes a rubber sleeve vibration plate 54, a fifth positioning member 55 and a sixth positioning member 56 for positioning the rubber sleeve 5 distributed and transmitted from the rubber sleeve vibration plate 54, and an eighth driving device 57 for driving the fifth positioning member 55 to move along the vertical direction; the fifth positioning member 55 and the sixth positioning member 56 are arranged at one end of the transmission channel of the rubber sleeve 5, and the sixth positioning member 56 limits the transmission direction of the rubber sleeve 5; a supporting platform connected with the transmission channel of the rubber sleeve 5 is arranged at the bottom thereof, and is used to receive the rubber sleeve 5 transmitted from the transmission channel of the rubber sleeve 5; the fifth positioning member 55 positions the rubber sleeve 5 laterally.

[0055] An ejection rod 43 and a fourth driving device 44 are provided on one side of the bottom of the third positioning member 40; an ejection hole is provided at the bottom of the first positioning groove 39, and the fourth driving device 44 can drive the ejection rod 43 to move in the ejection hole to eject the assembled body 1.

[0056] Specifically, the entire assembly process is described in detail below:

[0057] First, the main body 1 passes through the material distribution of the main body vibration disk 8, and enters the second discharge hole 26 of the main body 1 of the second positioning piece of the main body 1 with the installation cavity opening 70 facing upward, and is driven by the fourteenth driving device 23 to move on the upper end surface of the first positioning piece of the main body 1 so that the second discharge hole 26 of the main body can coincide with the first discharge port of the main body 1. The main body 1 placed in the second discharge hole 26 of the main body is discharged through the first discharge port of the main body 1 into the jig 7 on the turntable 6, and the fourteenth driving device 23 drives the first positioning piece of the main body 1 to return to the initial position to continue to receive the next body 1.

[0058] Then, the detection needle 32 placed directly above the jig 7 moves downward under the drive of the first driving device 33 to detect whether the installation cavity opening 70 of the main body 1 is facing directly upward; then the turntable 6 rotates to the next workstation, and the round plug 2 enters the second discharge hole of the round plug 2 through the distribution of the round plug vibration disk 10, and the fifteenth driving device 29 drives the second round plug positioning member 28 to move on the upper end surface of the first round plug positioning member 27, so that the second discharge hole of the round plug 2 coincides with the first discharge port of the round plug 2, and the round plug 2 is discharged through the first discharge port of the round plug 2 and enters the installation cavity of the main body 1 directly below.

[0059] Then, the turntable 6 rotates to the next workstation, and the spring 3 enters the positioning tube 34 through the distribution of the spring vibration disk 12. The second driving device 36 drives the positioning tube 34 to approach the installation cavity opening 70. At this time, the third driving device 37 drives the positioning plates to move away from each other, so that the limiting rods 35 move away from each other, and the spring 3 placed in the positioning tube 34 enters the installation cavity through the installation cavity opening 70.

[0060] Then, the turntable 6 rotates to the next station, the sixth driving device 52 drives the first mechanical gripper 50 to descend, the fifth driving device 51 drives the first mechanical gripper 50 to clamp the installation cavity opening 70 end of the body 1, the sixth driving device 52 drives the first mechanical gripper 50 to rise to make the body 1 leave the fixture 7, the seventh driving device 53 drives the first mechanical gripper 50 to move to the first positioning groove 39 of the third positioning member 40, at this time, the first positioning groove 39 is opened upward, and the sixth driving device 52 drives the first mechanical gripper 50 to move to the first positioning groove 39 of the third positioning member 40. The gripper 50 descends and places the main body 1 on the first positioning groove 39, and then the fifth driving device 51 drives the first mechanical gripper 50 to move to loosen the clamping of the main body 1, so that the main body 1 installed with the round plug 2 and the spring 3 is placed on the first positioning groove 39, and the second servo motor 42 drives the third positioning member 40 to move to a suitable height, and the first servo motor 41 drives the third positioning member 40 from the original state where the opening of the first positioning groove 39 faces directly upward to the state where the opening of the first positioning groove 39 faces horizontally to the side of the fourth positioning member 45.

[0061] At this time, the rubber sleeve 5 is divided by the rubber sleeve vibration disk 54, and enters the fifth positioning member 55 and the sixth positioning member 56 through the rubber sleeve 5 transmission channel with the installation opening facing upward; the flow limiter 4 is divided by the flow limiter vibration disk 59, and enters the seventh positioning member 61 through the flow limiter 4 transmission channel in the state shown in the accompanying drawing.

[0062] Then, the twelfth driving device 67 synchronously drives the second mechanical gripper 64 and the adsorption tube 65 to move, so that the second mechanical gripper 64 is placed above the rubber sleeve 5, and the adsorption tube 65 is placed above the flow limiter 4. The thirteenth driving device 68 and the sixteenth driving device 69 drive the second mechanical gripper 64 and the adsorption tube 65 to move in the vertical direction close to the rubber sleeve 5 and the flow limiter 4. The eighth driving device 57 drives the fifth positioning member 55 to move downward in the vertical direction so that there is space for grasping on both sides of the rubber sleeve 5. The eleventh driving device 66 enables the second mechanical gripper 64 to grasp the rubber sleeve 5, and the vacuum generator enables the adsorption tube 65 to adsorb the flow limiter 4.

[0063] Then, the second transfer mechanism 17 places the rubber sleeve 5 and the flow limiter 4 on the second positioning groove 49 of the fourth positioning member 45 in sequence, and the opening of the second positioning groove 49 is now facing upward; the third servo motor 46 drives the fourth positioning member 45 to flip, so that the installation opening of the rubber sleeve 5 is horizontally facing the installation cavity opening 70 of the main body 1, and the fourth servo motor 47 drives the fourth positioning member 45 to approach the third positioning member 40, so that the rubber sleeve 5 is pressed against the main body 1, thereby completing the valve core assembly; the second transfer mechanism 17 returns to its original position; finally, the fourth drive device 44 drives the ejector rod 43 to move, and ejects the assembled valve core from the first positioning groove 39 and drops it into the finished product collection box below.

[0064] Of course, when the detection needle 32 detects that the installation cavity opening 70 of the body 1 is not facing upward, the body 1 will not be assembled with the round plug 2 and the spring 3, and finally the first mechanical gripper 50 will grab it and drop it into the defective product collection box below. It should be noted that the entire assembly machine is controlled by an electronic control system, and the above-mentioned driving device can be a servo motor or a cylinder.

[0065] The assembly machine can realize the fully automated assembly of the valve core, greatly improving the efficiency of production assembly and reducing labor costs; the pressing mechanism uses a servo motor to position each assembly action, ensuring the position accuracy of the pressing and the torque during pressing, improving the quality of the product and reducing the number of defective products.
