When the rotating disc 110 drives the valve body positioning seat 120 with the valve body 10 mounted thereon to rotate to the assembling mechanism 400, the movable positioning block 410 is firstly started and drives the movable positioning block 410 to move to the upper side of the valve body positioning seat 120, at this time, the positioning hole 420 is just above the middle position of the valve body 10, an operator can put the spring 12, the positioning shell 13 and the upper cover 14 into the valve body 10 from the positioning hole 420, then the rotating disc 110 continues to drive the valve body positioning seat 120 to rotate to the lower side of the upper cover pressing piece 430, and the upper cover pressing piece 430 presses the upper cover 14 into the valve body 10 to complete the mounting of the valve body 10.

As shown in fig. 6, the assembling mechanism 400 is further provided with a grating, the grating can control the rotation of the rotating disc 110 to stop when the operator puts the spring 12, the positioning shell 13 and the upper cover 14 into the valve body, the rotating disc 110 can continue to rotate after the operator finishes the throwing action and leaves the grating, and the grating can protect the operator to prevent the operator from being crushed when the rotating disc 110 rotates suddenly.

As shown in fig. 7, a second motor 431 is arranged on the upper cover pressing member 430 along the vertical direction, a squeezing block 432 is arranged at the output end of the second motor 431, and the second motor 431 can drive the squeezing block 432 to move in the vertical direction.

When the rotating disc 110 drives the valve body with the spring 12, the positioning shell 13 and the upper cover 14 placed thereon to rotate to a position right below the extrusion block 432, the second motor 431 pneumatically drives the extrusion block 432 to move downwards to press the upper cover 14 against the valve body.

As shown in fig. 3 and 8, the airtightness detection mechanism 500 is provided with a positive pressure detection assembly and a negative pressure detection assembly that are identical, and both the positive pressure detection assembly and the negative pressure detection assembly include: the fourth cylinder 510 is arranged on the machine table 100, an output end of the fourth cylinder 510 is provided with an air source connector 520, the air source connector 520 is used for connecting an air source, and the air source connector 520 is provided with a fourth sensor 530; the output end of each plug cylinder 540 is provided with a plug 550, and each plug cylinder 540 can move the plug 550 to be tightly abutted to the valve body.

The positive pressure detection assembly and the negative pressure detection assembly are used for detecting the gas leakage condition after the inside of the assembled valve body is connected with a gas source, specifically, when the rotating disc 110 drives the assembled valve body to rotate to the positive pressure detection assembly, the fourth cylinder 510 connected with the gas source drives the gas source connector 520 to abut against the gas inlet port of the valve body, the plug cylinder 540 drives the plug 550 to abut against the gas outlet port of the valve body, then the gas source connector 520 supplies gas into the valve body, and the fourth sensor 530 starts to detect the gas circulation condition inside the valve body; after the positive pressure detection is completed, the rotating disc 110 continues to drive the valve body to rotate to the negative pressure detection for negative pressure detection, the negative pressure detection of the negative pressure detection assembly on the valve body 10 is basically consistent with the positive pressure detection, only the air source connector 520 is changed from inflating into extracting air from the valve body 10, and the fourth sensor 530 is used for detecting the air flowing condition in the valve body 10.

As shown in fig. 3 and 9, the sorting mechanism 600 is provided with two identical valve body moving assemblies, each of which includes: the supporting frame 610 is arranged on the machine table 100 along the vertical direction, and a fifth cylinder 620 is arranged on the supporting frame 610 along the horizontal direction; the moving member 630 is arranged on the support frame 610 and connected to the output end of the fifth cylinder 620, the fifth cylinder 620 can drive the moving member 630 to move on the support frame 610, the sixth cylinder 640 is arranged on the moving member 630 in the vertical direction, and the output end of the sixth cylinder 640 is provided with the second valve body clamping jaw cylinder 650.

Two identical valve body moving assemblies can be used for snatching respectively that the malleation detects unqualified malleation and detects qualified, negative pressure detects qualified malleation and detects unqualified, positive negative pressure and detects unqualified and positive negative pressure and detect qualified valve body, and concrete distribution mode can be confirmed according to actual conditions, and the specific operation process of valve body moving assembly is as follows: when the rotating disc 110 rotates the valve body after being inspected by the air tightness inspection mechanism 500 onto the sorting mechanism 600, the fifth cylinder 620 acts to control the moving member 630 to move on the supporting frame 610, so that the second valve body clamping jaw cylinder 650 moves right above the valve body positioning seat 120, then the sixth cylinder 640 acts to drive the second valve body clamping jaw cylinder 650 to approach towards the valve body until the second valve body clamping jaw cylinder 650 can grab the valve body, after the second valve body clamping jaw grabs the valve body, the sixth cylinder 640 drives the second valve body cylinder to move upwards to the initial height, and finally the sixth cylinder 640 drives the second valve body clamping jaw cylinder 650 to move back to the initial position.

As shown in fig. 3, a fifth sensor is further disposed on the rotary disc 110, a detection direction of the fifth sensor is opposite to the valve body loading mechanism 200, the fifth sensor is used as a start switch of the rotary disc 110, and the rotary disc 110 can be controlled to start rotating after the fifth sensor senses that a valve body is placed on the valve body positioning seat 120.
