Description

Technical Field

[0001] The invention relates to the technical field of valve body assembly equipment, in particular to a valve body assembly and air tightness detection device. Background Art

[0002] The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. The valve body is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop and can control its flow. The material of the valve body is selected according to different process media. Commonly used materials are: cast iron, cast steel, stainless steel, carbon steel, plastic, copper, etc.

[0003] As a pipeline control part in the process of gas or liquid transmission, the valve body is widely used in industries closely related to residents' lives and industrial production, such as gas and oil. Since valve bodies are mostly made of metal materials, compressed gas or liquid is transported through pipelines. If there is a leak between the valve body and the pipeline, it will cause some very serious consequences. In addition to affecting the function of the product itself, it will also cause dangerous events such as fire and explosion in serious cases, causing great losses to people's lives and property. In addition, when small burrs appear on the inlet and outlet ports of the valve body, it will also have a great impact on its use. Therefore, valve body inspection is related to the safety of people's lives and property. In order to ensure the quality of the product and the safety of the valve body, the valve body must be inspected for burrs and sealing performance during the assembly process and before leaving the factory.

[0004] like Figure 1 A three-way valve is shown, which includes a valve body 10, a gasket 11, a spring 12, a positioning shell 13 and an upper cover 14. In the prior art, the valve body 10 needs to be manually inspected to check whether there are burrs on its inlet and outlet ports. After the inspection, the valve body is placed on a press for assembly, and finally placed on an airtightness detection device for airtightness detection. The traditional assembly and detection method uses manual detection, which has a relatively large workload and is prone to burrs or airtightness leakage. Summary of the invention

DETAILED DESCRIPTION

[0053] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0054] like Figures 2 to 3 As shown, a valve body assembly and air tightness detection device of the present invention includes: a machine platform 100, a valve body feeding mechanism 200, a gasket feeding mechanism 300, an assembly mechanism 400, an air tightness detection mechanism 500 and a sorting mechanism 600.

[0055] A rotating disk 110 is provided at the upper end of the machine 100, and a plurality of valve body positioning seats 120 are provided on the rotating disk 110; a valve body feeding mechanism 200 is provided on the machine 100, and the valve body feeding mechanism 200 can put the valve body 10 into the valve body positioning seat 120; a gasket feeding mechanism 300 is provided on the machine 100 and is located on the side of the valve body feeding mechanism 200, and a suction pipe 310 is provided on the gasket feeding mechanism 300, and the suction pipe 310 can put the gasket 11 into the valve body 10, and the suction pipe 310 is a hollow cylindrical tube, and the outer diameter of the suction pipe 310 is smaller than the diameter of the gasket, and the upper end of the suction pipe 310 is used to connect the air source. When working, the lower end of the suction pipe 310 is pressed against the upper surface of the gasket, and the suction pipe 310 is connected to the air source, and then the air source extracts the air in the suction pipe 310. The body generates negative pressure inside the suction tube 310, so that the suction tube 310 can absorb the gasket 11 and drive the gasket 11 to move; the assembly mechanism 400 is arranged on the machine platform 100 and is located on the side of the gasket feeding mechanism 300, and the assembly mechanism 400 can install the spring 12, the positioning shell 13 and the upper cover 14 on the valve body 10; the airtightness detection mechanism 500 is arranged on the machine platform 100 and is located on the side of the assembly mechanism 400, and the airtightness detection mechanism 500 is used to detect the airtightness of the assembled valve body 10; the sorting mechanism 600 is arranged on the machine platform 100 and is located between the valve body feeding mechanism 200 and the airtightness detection mechanism 500, and the sorting mechanism 600 can grab the valve body 10 in the valve body positioning seat 120 that has been detected by the airtightness detection mechanism 500 from the valve body positioning seat 120.

[0056] The rotating disk 110 is arranged on the machine platform 100. When working, the rotating disk 110 can drive the valve body positioning seat 120 to rotate on the rotating disk 110 around the axis direction of the rotating disk 110. The valve body feeding mechanism 200 can put the valve body 10 to be assembled into the valve body positioning seat 120. After the valve body 10 is placed on the valve body positioning seat 120, the rotating disk 110 drives the valve body positioning seat 120 to move toward the direction of the gasket feeding mechanism 300. When the valve body positioning seat 120 moves to the preset position, the suction pipe 310 arranged on the gasket feeding mechanism 300 can put the gasket 11 to be assembled into the valve body 10, and then assemble the gasket 11 and the valve body 10 together. Then the rotating disk 110 continues to drive the valve body positioning seat 120 to rotate toward the assembly mechanism 400. When the valve body positioning seat 120 rotates to the bottom of the assembly mechanism 400, the operator can put the spring 12, the positioning shell 13 and the upper cover 14 into In the valve body, the upper cover 14 is pressed into the valve body 10 through the assembly mechanism 400 to complete the installation of the valve body 10, and then the rotating disk 110 continues to drive the valve body positioning seat 120 to rotate toward the airtightness detection mechanism 500. When the valve body positioning seat 120 moves the assembled valve body 10 to the bottom of the airtightness detection mechanism 500, the airtightness detection mechanism 500 performs an airtightness detection on the valve body 10, and then the rotating disk 110 continues to rotate with the valve body positioning seat 120. When the valve body positioning seat 120 rotates with the valve body that has been tested to the bottom of the sorting mechanism 600, the sorting mechanism 600 can grab the valve body 10 that is qualified and the valve body 10 that is unqualified from the valve body positioning seat 120 and distinguish them. At this point, the assembly and airtightness detection of the valve body 10 are completed. The device of the present invention has a high degree of automation, can improve the efficiency of valve body assembly and airtightness detection, and greatly shortens the production time of the valve body.

[0057] like Figure 3 and Figure 4 As shown, the valve body feeding mechanism 200 includes: a valve body positioning block 210, which is arranged on the machine platform 100, and the valve body positioning block 210 is used to place the valve body 10 to be assembled; a valve body detection component 220, which is arranged on the machine platform 100, and the valve body detection component 220 can detect whether there are burrs on the valve body 10; a valve body picking component 230, which is arranged on the machine platform 100, and the valve body picking component 230 is movably provided with a plurality of first valve body clamping cylinders 231, and the first valve body clamping cylinders 231 can grab the valve body 10 on the valve body positioning block 210 and put it on the valve body detection component 220 for detection.

[0058] During operation, the first valve body clamping cylinder 231 arranged on the valve body picking piece 230 grabs the valve body 10 on the valve body positioning block 210 and puts it on the valve body detection piece 220 for detection. The valve body detection piece 220 mainly detects whether there are burrs on the valve body's air inlet and outlet ports. After the detection is completed, the first valve body clamping cylinder 231 grabs the valve body 10 and puts it on the valve body positioning seat 120 for the next process.

[0059] Specifically, the valve body detection member 220 includes: a fixed seat 221, which is arranged on the machine 100, and a first motor 222 is arranged on the fixed seat 221; a rotation positioning platform 223, which is arranged at the output end of the first motor 222, and the first motor 222 can drive the rotation positioning platform 223 to rotate on the fixed seat 221; a first sensor 224, which is arranged between the valve body positioning block 210 and the fixed seat 221 and is electrically connected to the first motor 222, and the first sensor 224 can record the direction of the valve body and transmit it to the first motor 222; The second sensor 225 is arranged on the valve body picking piece 230 and is electrically connected to the first valve body clamping cylinder 231. The second sensor 225 is used to detect whether there are burrs on the valve body; the light source 226 is movably arranged on the valve body picking piece 230 in the vertical direction and is directly above the rotating positioning platform 223; the storage box 227 is arranged on one side of the fixed seat 221. When the second sensor 225 detects that there are burrs on the valve body 10, the first valve body clamping cylinder 231 can grab the valve body 10 with burrs into the storage box 227.

[0060] The first valve body gripper cylinder 231 first grabs the valve body 10 to the top of the first sensor 224. The first sensor 224 determines the position of the valve body 10 by comparing the direction of the arrow on the lower end surface of the valve body 10. Then the first sensor 224 transmits the detection data to the first motor 222. The first motor 222 adjusts the posture of the rotary positioning platform 223 according to the data transmitted by the first sensor 224, so that when the first valve body gripper cylinder 231 grabs the valve body 10, the relative position of the valve body 10 and the rotary positioning platform 223 is always consistent. After the rotary positioning platform 223 receives the valve body 10 transported by the first valve body gripper cylinder 231, the light source 226 moves vertically downward and is aligned with the rotary positioning platform The valve body 10 on 223 is against each other, so that the light emitted by the light source 226 can be emitted from the air inlet and outlet ports of the valve body. At this time, the first motor 222 starts and drives the rotary positioning platform 223 to drive the valve body 10 to rotate. The second sensor 225 determines the condition of the burrs inside the valve body 10 by detecting the light emitted from the valve body 10. After the detection is completed, the light source 226 moves back to the initial position. When the second sensor 225 detects that there are burrs inside the valve 10, the first valve body clamping claw cylinder 231 grabs the valve body 10 with the burrs into the storage box 227; when the second sensor 225 detects that there are no burrs inside the valve body 10, the first valve body clamping claw cylinder 231 grabs the valve body 10 onto the valve body positioning seat 120.

[0061] like Figure 4As shown, the valve body material picking part 230 also includes: a fixed frame 232, which is arranged on the machine platform 100, and a first cylinder 233 that can move in the horizontal direction is provided on the fixed frame 232; a movable frame 234, which is arranged at the output end of the first cylinder 233, and when the first cylinder 233 is actuated, it can drive the movable frame 234 to move in the vertical direction, and each first valve body clamping cylinder 231 is arranged on the movable frame 234.

[0062] The horizontal movement of the first cylinder 233 on the fixing frame 232 can realize the horizontal movement of the moving member 630 , and the first cylinder 233 realizes the vertical movement of the first valve body clamping cylinder 231 by driving the moving member 630 to move in the vertical direction.

[0063] like Figure 5 As shown, the gasket feeding mechanism 300 also includes: a gasket positioning block 320, which is arranged on the machine platform 100, and a third sensor 330 is provided on the gasket positioning block 320; a vertical plate 340, which is arranged on the machine platform 100 and is located on one side of the gasket positioning block 320, and a horizontally arranged second cylinder 350 is provided on the vertical plate 340; a moving platform 360, which is arranged on the vertical plate 340 and connected to the output end of the second cylinder 350, the second cylinder 350 can drive the moving platform 360 to move horizontally on the vertical plate 340, and a third cylinder 370 is provided on the moving platform 360, and a suction pipe 310 is connected to the output end of the third cylinder 370, and the third cylinder 370 can drive the suction pipe 310 to move in the vertical direction.

[0064] The third sensor 330 is used to detect whether there is a gasket on the gasket positioning block 320. When the third sensor 330 detects that a gasket is placed on the gasket positioning block 320, the third cylinder 370 drives the suction pipe 310 to move downward to absorb the gasket 11. After the suction pipe 310 absorbs the gasket 11, the second cylinder 350 drives the moving platform 360 to move horizontally on the vertical plate 340 to the valve body positioning seat 120. After the suction pipe 310 moves to the preset position, the suction of the gasket is released, and the gasket 11 is assembled into the valve body 10. Then the second cylinder 350 drives the suction pipe 310 back to the initial position, waiting for the next gasket 11 movement operation.

[0065] like Figure 3 , Figure 6 and Figure 7 As shown, the assembly mechanism 400 includes: a movable positioning block 410, which is movably arranged on the machine platform 100, and a positioning hole 420 is provided on the movable positioning block 410, and the positioning hole 420 is used to place the spring 12, the positioning shell 13 and the upper cover 14; an upper cover pressing member 430, which is arranged on the machine platform 100 and is located on the side of the movable positioning block 410, and the upper cover pressing member 430 is used to press the upper cover 14 onto the valve body 10.

[0066] When the rotating disk 110 drives the valve body positioning seat 120 equipped with the valve body 10 to rotate onto the assembly mechanism 400, the movable positioning block 410 is first started and drives the movable positioning block 410 to move above the valve body positioning seat 120. At this time, the positioning hole 420 is just above the middle position of the valve body 10. The operator can put the spring 12, the positioning shell 13 and the upper cover 14 into the valve body 10 through the positioning hole 420. Then the rotating disk 110 continues to drive the valve body positioning seat 120 to rotate to the bottom of the upper cover clamping piece 430, and the upper cover clamping piece 430 presses the upper cover 14 into the valve body 10 to complete the installation of the valve body 10.

[0067] like Figure 6 As shown, a blocking grating is also provided on the assembly mechanism 400. The blocking grating can control the rotating disk 110 to stop rotating when the operator puts the spring 12, the positioning shell 13 and the upper cover 14 into the valve body. The rotating disk 110 can continue to rotate only after the operator completes the placement action and leaves the blocking grating. The blocking grating can protect the operator and prevent the operator from being crushed when the rotating disk 110 rotates suddenly.

[0068] like Figure 7 As shown, a second motor 431 is provided on the upper cover pressing member 430 in the vertical direction, and an extrusion block 432 is provided at the output end of the second motor 431 . The second motor 431 can drive the extrusion block 432 to move in the vertical direction.

[0069] When the rotating disk 110 drives the valve body with the spring 12, the positioning shell 13 and the upper cover 14 to rotate to just below the extrusion block 432, the second motor 431 pneumatically drives the extrusion block 432 to move downward to press the upper cover 14 into the valve body.

[0070] like Figure 3 and Figure 8 As shown, the air tightness detection mechanism 500 is provided with completely identical positive pressure detection components and negative pressure detection components, and both the positive pressure detection components and the negative pressure detection components include: a fourth cylinder 510, which is arranged on the machine 100, and the output end of the fourth cylinder 510 is provided with an air source connector 520, and the air source connector 520 is used to connect the air source, and the air source connector 520 is provided with a fourth sensor 530; a plurality of plug cylinders 540, and each plug cylinder 540 has a plug 550 at its output end, and each plug cylinder 540 can move the plug 550 to be tightly against the valve body.

[0071] The positive pressure detection component and the negative pressure detection component are used to detect gas leakage after the gas source is connected to the inside of the valve body after the assembly is completed. Specifically, when the rotating disk 110 rotates with the assembled valve body to the positive pressure detection component, the fourth air cylinder 510 after the air source is connected drives the air source connector 520 to press against the air inlet port of the valve body, and the plug cylinder 540 drives the plug 550 to press against the air outlet port of the valve body, and then the air source connector 520 supplies air into the valve body, and the fourth sensor 530 starts to detect the gas flow inside the valve body; after the positive pressure detection is completed, the rotating disk 110 continues to drive the valve body to rotate to the negative pressure detection test for negative pressure detection. The negative pressure detection of the valve body 10 by the negative pressure detection component is basically the same as the positive pressure detection, except that the air source connector 520 changes from inflating into the valve body to extracting gas from the valve body 10, and the fourth sensor 530 also detects the gas flow in the valve body 10.

[0072] like Figure 3 and Fig. 9 As shown, the sorting mechanism 600 is provided with two completely identical valve body moving components, and each valve body moving component includes: a support frame 610, which is arranged on the machine 100 in the vertical direction, and a fifth cylinder 620 is arranged on the support frame 610 in the horizontal direction; a moving part 630, which 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 part 630 to move on the support frame 610, and the moving part 630 is provided with a sixth cylinder 640 arranged in the vertical direction, and the output end of the sixth cylinder 640 is provided with a second valve body clamping cylinder 650.

[0073] Two completely identical valve body moving assemblies can be used to respectively grab valve bodies that fail the positive pressure test and pass the positive pressure test, that pass the negative pressure test and fail the positive pressure test, that fail the positive and negative pressure tests, and that pass the positive and negative pressure tests. The specific allocation method can be determined according to actual conditions. The specific operation process of the valve body moving assembly is as follows: when the rotating disk 110 rotates the valve body that has been inspected by the airtightness detection mechanism 500 to the sorting mechanism 600, the fifth cylinder 620 controls the moving part 630 to move on the support frame 610, so that the second valve body clamping cylinder 650 moves to the top of the valve body positioning seat 120, and then the sixth cylinder 640 drives the second valve body clamping cylinder 650 to approach the valve body until the second valve body clamping cylinder 650 can grab the valve body. After the second valve body clamp grabs the valve body, the sixth cylinder 640 drives the second valve body cylinder to move upward to the initial height. Finally, the sixth cylinder 640 drives the second valve body clamping cylinder 650 back to the initial position.
