[0028] A sealing ring conveyor belt 1, on which sleeve rings 2 are evenly spaced, and on which an O-type rubber sealing ring 3 is sleeved, the movement of the sealing ring conveyor belt 1 drives the O-type rubber sealing ring 3 to move toward one side of the transfer manipulator 4;

[0029] The transfer robot 4 includes a base 5, which is fixedly connected to a hinged disk 6. A plurality of sleeve frames 8 are installed in a circular array on the hinged disk 6 through a rotating shaft 7. Conveying hook belts 9 are installed on the sleeve frames 8. The conveying hook belts 9 are driven by a rotating motor installed on each sleeve frame 8 to reciprocate. A tensioning mechanism is also provided on the base 5 to drive the plurality of sleeve frames 8 to perform synchronous rotation around the rotating shaft 7 at the upper end thereof. Through the setting of the tensioning mechanism, the elastic force of the O-type rubber sealing ring 3 is detected synchronously during the process of grabbing and transferring the O-type rubber sealing ring 3. The plurality of conveying hook belts 9 arranged in a circular array grab the O-type rubber sealing ring 3 conveyed on the sealing ring conveyor belt 1 and move it to one side of the sealing detection box 10; and,

[0030] A sealing test box 10 is provided with an airtight test platform 11 in the sealing test box 10, and a transfer robot 4 is used to transfer the O-type rubber sealing ring 3 to the airtight test platform 11, and an annular guide rail 12 is fixedly installed above the airtight test platform 11, and a plurality of sealing pressure plates 13 are slidingly and translationally arranged on the annular guide rail 12, and the plurality of sealing pressure plates 13 are alternately moved to the top of the airtight test platform 11, and a sealing push block 14 is also telescopically installed above the airtight test platform 11, and the sealing push block 14 pushes the sealing pressure plate 13 to move toward the side of the airtight test platform 11 so as to seal and squeeze the O-type rubber sealing ring 3, and the airtight test platform 11 and the sealing pressure plate 13 are enclosed to form an airtight test cabin 15, and an airtight test device is installed on one side of the airtight test cabin 15, so as to perform an airtight test on the O-type rubber sealing ring 3, and the O-type rubber sealing ring 3 after the test is completed is moved out of the sealing test box 10 by the adsorption of the sealing pressure plate 13.

[0031] In this embodiment, the sealing ring conveyor belt 1 is used to transport the O-type rubber sealing ring 3 with detection to one side of the transfer robot 4. The sealing ring conveyor belt 1 is evenly spaced with rings 2, and the O-type rubber sealing ring 3 is fixed by the rings 2. The rings 2 are comb-shaped structures arranged in an annular array, and grooves are provided on the rings for the O-type rubber sealing ring 3 to be embedded. After the O-type rubber sealing ring 3 is embedded in the rings 2, it is grabbed by the transfer robot 4. The front base 5 of the transfer robot 4 is installed on the multi-degree-of-freedom robot arm 20. The transfer robot 4 is provided with a conveyor hook belt 9 arranged in an annular array. The conveyor hook belt 9 moves under the drive of the rotating motor installed respectively.

Figure 3 At this time, the periphery of the transfer robot 4 has grabbed multiple O-type rubber sealing rings 3. In order to improve the detection efficiency, multiple transfer robots 4 can be set in this embodiment. When one is picking up the O-type rubber sealing ring 3, the other performs subsequent detection operations. When the transfer robot 4 completes the picking of multiple O-type rubber sealing rings 3, it can drive the sleeve frame 8 to stretch outwards through the set tensioning mechanism to achieve the attachment of the specification. Figure 3 In the rightmost state, before the release of the O-type rubber sealing ring 3, the extension and resilience of each O-type rubber sealing ring 3 are tested. When the O-type rubber sealing ring 3 needs to be released, the drive sleeve frame 8 is changed to the state attached to the instruction manual. Figure 3 The shape on the left side of the middle, at this time, the O-type rubber sealing ring 3 can be driven to separate from the transfer robot 4 through the rotation of the rotating motor. When the O-type rubber sealing ring 3 falls onto the airtightness detection platform 11, the sealing pressure plate 13 is driven to squeeze it, and the airtightness detection device is used to perform an airtightness detection.

The threaded screw 16 is provided with a lifting drive block 18 on its outer sleeve, and a plurality of support rods 19 are installed on the lifting drive block 18 in a circular array through the rotating shaft 7. The plurality of support rods 19 correspond to the socket frames 8 one by one, and the ends of the plurality of support rods 19 away from the lifting drive block 18 are hinged on the corresponding socket frames 8. The lifting and lowering of the lifting drive block 18 synchronously drives the plurality of socket frames 8 to shrink inward or stretch outward, thereby detecting the elastic force of the O-ring 3.

[0033] In this embodiment, the specific structure of the tensioning mechanism is further disclosed, where the tensioning motor 17 drives the lifting drive block 18 to perform lifting movement, and simultaneously drives the plurality of sleeve frames 8 to shrink inward or stretch outward, thereby detecting the elastic force of the O-type rubber sealing ring 3. Embodiment three:

[0034] The sealing pressure plates 13 are arranged one-to-one under a plurality of sliding seats 21, and the sliding seats 21 are slidably and translationally sleeved on the annular guide rail 12. Push plates 22 are also arranged one-to-one above the plurality of sliding seats 21. The sealing pressure plates 13 and the push plates 22 are fixedly connected by a plurality of sliding rods 23, and the sliding rods 23 are slidably arranged in the sliding rod holes provided in the sliding seats 21. Extrusion springs 24 are installed between the push plates 22 and the sliding seats 21. The extrusion springs 24 push the sealing pressure plates 13 to move toward the side close to the sliding seats 21 in the absence of external force. The sealing push block 14 is fixedly connected to the telescopic arm of the hydraulic telescopic mechanism, and the hydraulic telescopic mechanism is installed in the sealing detection box 10. The lifting and lowering movement of the sealing push block 14 pushes the push plate 22 and the sealing pressure plate 13 to perform synchronous lifting and lowering movements.

[0035] In this embodiment, the connection mechanism of the sealing pressure plate 13 is further disclosed, which performs lifting movement under the impetus of the hydraulic telescopic mechanism, and performs translational sliding during the translational movement of the sliding seat 21 around the annular guide rail 12, thereby performing the airtightness detection of the O-ring 3 and the operation of removing it. Embodiment 4:

[0036] An annular sealing groove 25 is correspondingly provided on the sealing platen 13 and the airtightness testing platform 11. An airtightness retaining rubber ring 26 is also installed on one side of the annular sealing groove 25 of the airtightness testing platform 11. The sealing platen 13 and the airtightness testing platform 11 enclose an airtightness testing cabin 15. A helium inlet pipe 27 is connected to one side of the sealing platen 13 through a pipeline. The helium inlet pipe 27 is connected to an external helium pump. The helium inlet pipe 27 is connected to an air outlet 28 provided at the axis of the sealing platen 13. An exhaust pipe 29 is also connected to the airtightness testing platform 11 on one side of the airtightness testing cabin 15. The exhaust pipe 29 is connected to a helium detector 30. The helium content in the airtightness testing cabin 15 is detected by the helium detector 30, so as to determine whether the helium on one side of the air outlet 28 enters the airtightness testing cabin 15. The air outlet 28 and the airtightness testing cabin 15 are respectively arranged on the inner and outer sides of the O-type rubber sealing ring 3.

[0037] In this embodiment, an air tightness detection mechanism built into the air tightness detection platform 11 is further disclosed, and its main body is a helium detector 30. Since helium has stable chemical properties and low density, it is easy to seep out through tiny gaps, and the helium detector has extremely high sensitivity. Therefore, helium is released to the inner ring of the O-type rubber sealing ring 3 through the air outlet 28. When the helium content in the air tightness detection chamber 15 of the outer ring of the O-type rubber sealing ring 3 exceeds the standard, it indicates that the O-type rubber sealing ring 3 is leaking. In this way, the air tightness of the sealing ring can be detected more accurately. Embodiment five:

[0038] An embedding groove 31 for embedding the O-type rubber sealing ring 3 is provided on one side where the sealing plate 13 and the airtightness detection platform 11 abut against each other. A negative pressure adsorption hole 32 is also provided in the embedding groove 31 on one side of the sealing plate 13. The negative pressure adsorption hole 32 is connected to a negative pressure tube 33 installed on one side of the sealing plate 13. The negative pressure tube 33 is connected to an external negative pressure vacuum pump. The O-type rubber sealing ring 3 is adsorbed on the bottom of the sealing plate 13 by the pumping of air by the vacuum pump, and is moved out of the sealing detection box 10 as the sliding seat 21 moves.

[0039] In this embodiment, a suction and removal mechanism for the O-type rubber sealing ring 3 is further disclosed. By opening a negative pressure suction hole 32 in the embedding groove 31 of the sealing pressure plate 13, and using an external negative pressure suction pump to evacuate air, the O-type rubber sealing ring 3 is forced to be firmly adsorbed in the embedding groove 31, and rises with the rise of the sealing pressure plate 13, and finally moves out of the sealing detection box 10.

[0040] The air tightness testing platform 11 is also installed on a lifting seat 34 , and a lifting hydraulic push rod 35 is provided on the lifting seat 34 for driving the air tightness testing platform 11 to perform lifting movement.
