[0041] See also Figure 1 、 Figure 2 and Figure 6 The docking assembly 52 includes a detector 521 installed on the upper side of the horizontal section of the L-shaped mounting frame 51, and a bellows 522 is installed on the lower side of the detector 521, which passes through the horizontal section of the L-shaped mounting frame 51 from top to bottom. A mounting pipe 523 is fixedly provided at the lower end of the bellows 522, and a quick-connect female connector 2 is installed at the lower end of the mounting pipe 523. A U-shaped frame 524 is fixedly provided on the mounting pipe 523 in a left-right symmetrical manner through an L-shaped connecting frame.

[0042] See also Figure 1 、 Figure 2 and Figure 6The driving component 2 56 includes a pneumatic cylinder 1 561 fixedly arranged on the front side of the vertical section of the L-shaped mounting frame 51 by a support 4, and the telescopic ends of the pneumatic cylinder 1 561 are fixedly provided with a sliding sleeve 562 that moves up and down and is elastically slidably connected to the mounting tube 523 through a spring. The lower side of the sliding sleeve 562 is fixedly provided with a connecting plate 563 symmetrically on the left and right, and the lower end of the connecting plate 563 is fixedly provided with a rack 1 564 symmetrically front and back through a U-shaped connecting frame.

[0043] When the quick-connect male connector 1 to be tested is aligned with the quick-connect female connector 2 under the transportation of the rotating disk 421, the sliding sleeve 562 is driven downward by the pneumatic cylinder 1 561, and the sliding sleeve 562 then presses the mounting tube 523 downward through the spring. The mounting tube 523 then stretches the bellows 522 downward and drives the quick-connect female connector 2 at the lower end to be aligned and inserted into the mounting end of the quick-connect male connector 1. At this time, the mounting tube 523 can no longer move downward.

[0044] See also Figure 2 、 Figure 6 and Figure 7 The release assembly 53 includes a support two that is symmetrically fixed on the U-shaped frame 524 near the side of the mounting tube 523, and a slide rail 531 is symmetrically fixed on the opposite side of the support two through a connecting rod. A slider 532 that moves left and right is slidably provided on the slide rail 531, and a return frame 533 is fixed between the front and back symmetrical sliders 532. The return frame 533 is sleeved on the upper end of the corresponding clamping part on the quick-connect female head 2, and a tooth plate 1 534 is fixed on the side of the return frame 533 away from the mounting tube 523. The upper side of the tooth plate 1 534 is meshed with a gear 2 535. The gear 2 535 is symmetrically fixed on the front and back through a rod member 1 with a gear 3 536 that is rotatably connected to the U-shaped frame 524 through a connecting shaft 1, and the rack 1 564 is meshed with the corresponding gear 3 536 for transmission.

[0045] When the quick-connect female head 2 and the quick-connect male head 1 are aligned and plugged in, the pneumatic cylinder 1 561 continues to drive the sliding sleeve 562 to move downward, and the sliding sleeve 562 then moves downward along the mounting tube 523 and synchronously drives the U-shaped connecting frame and the rack 1 564 to move downward through the connecting plate. The rack 1 564 then drives the corresponding gear 2 535 to rotate synchronously through the meshing transmission with the corresponding gear 3 536. The gear 2 535 then drives the return frame 533 and the slider 532 along the corresponding slide rail 531 toward the direction close to the quick-connect female head 2 through the meshing transmission with the corresponding tooth plate 1 534 until the rack 1 564 is completely disengaged from the gear 3 536. At this time, the upper end of the unmated clamping part on the quick-connect female head 2 is just attached to the inner surface of the corresponding return frame 533, close to the side of the corresponding tooth plate 1 534.

[0046] When the quick-connect female head 2 is aligned with the quick-connect male head 1 through the clamping piece under the action of the fastening component 54, the upper end of the clamping piece that has been docked and installed on the quick-connect female head 2 is just attached to the side of the inner surface of the corresponding return frame 533 away from the corresponding tooth plate 1 534, and the pneumatic cylinder 1 561 drives the rack 1 564 to move upward, and the rack 1 564 then drives the corresponding gear 2 535 to rotate synchronously through the meshing transmission with the corresponding gear 3 536, and the gear 2 535 then drives the corresponding gear 2 535 to rotate synchronously through the meshing transmission with the corresponding tooth plate 1 534. The return frame 533 and the slider 532 are driven to move along the corresponding slide rail 531 in the direction away from the quick-connect female head 2, and the return frame 533 synchronously pulls the upper end of the clamping part until the lower end of the clamping part deflects outward and disengages from the arc-shaped clamping groove on the quick-connect male head 1, thereby releasing the installation lock of the quick-connect female head 2 and the quick-connect male head 1. At this time, the upward-moving sliding sleeve 562 can just drive the quick-connect female head 2 to move upward and reset through the mounting tube 523 until the quick-connect female head 2 and the quick-connect male head 1 are completely separated.

[0047] See also Figure 2 、 Figure 6 and Figure 8 The fastening assembly 54 includes a rod member 2 fixedly arranged on the lower side of the support 2, and a tooth plate 2 541 that moves up and down is slidably arranged on the front and rear symmetrical rod members 2. A fastening block 542 that is press-fitted with the corresponding clip on the quick-connect female head 2 is fixedly arranged on the side of the tooth plate 2 541 close to the mounting tube 523. The side of the tooth plate 2 541 away from the mounting tube 523 is meshed with a gear 4 543 that is rotatably connected to the corresponding U-shaped frame 524 through the connecting shaft 2, and the rack 1 564 is meshed with the corresponding gear 4 543 for transmission.

[0048] When the rack 1 564 that continues to move downward is completely disengaged from the gear 3 536, the rack 1 564 drives the gear 4 543 to rotate through meshing transmission, and the gear 4 543 drives the fastening block 542 to move upward through meshing transmission with the tooth plate 2 541, and the fastening block 542 is then attached to the side of the corresponding clamping part away from the quick-connect male head 1. As the rack 1 564 continues to move upward, the fastening block 542 continues to press the corresponding clamping part, causing the lower end of the clamping part to deflect inward and stably engage with the arc-shaped clamping groove on the quick-connect male head 1, so that the quick-connect female head 2 and the quick-connect male head 1 to be tested are stably installed and locked together, wherein the corresponding square through groove on the rotating disk 421 can prevent the rotating disk 421 from obstructing the downward-moving rack 1 564 and tooth plate 2 541.

[0049] When rack 1 564 moves upward from the bottom to reset, rack 1 564 then moves the fastening block 542 downward to reset through gear 4 543 and disengages from the corresponding clamping piece until rack 1 564 is completely disengaged from gear 4 543 and meshes with gear 3 536 for transmission. Gear 3 536 then makes the return frame 533 pull the upper end of the corresponding clamping piece through gear plate 1 534, thereby releasing the installation lock of the quick-connect female connector 2 and the quick-connect male connector 1.

[0050] The above-mentioned operation method can realize the automatic and rapid alignment and stable installation of the quick-connect male connector 1 and the quick-connect female connector 2, and automatically release the installation lock of the quick-connect male connector 1 and the quick-connect female connector 2 after the inspection is completed, and at the same time, the quick-connect female connector 2 and the quick-connect male connector 1 are synchronously and stably separated, thereby not only greatly improving the overall efficiency of the installation, disassembly and air tightness testing of the quick-connect male connector 1, but also greatly reducing the overall burden of manual installation and disassembly operations, and reducing the overall labor cost.

[0051] See also Figure 6 、 Figure 7 and Figure 8 The positioning assembly 55 includes a positioning rotating plate 551 fixedly set on the end of the connecting shaft away from the corresponding gear three 536 and the end of the connecting shaft away from the corresponding gear four 543. A card slot 552 is provided on the upper side of the positioning rotating plate 551. A spring rod 553 is elastically slidably provided on the U-shaped frame 524 and above the corresponding positioning rotating plate 551 through the support three. The lower end of the spring rod 553 is fixedly provided with a card block 554 that moves up and down and engages with the corresponding card slot 552.

[0052] When rack 1 564 is completely disengaged from the corresponding gear 3 536 or gear 4 543, the positioning rotating plate 551, which rotates synchronously with gear 3 536 or gear 4 543, drives the slot 552 to align with the corresponding block 554. Under the action of the spring rod 553, the block 554 is then snapped downward into the corresponding slot 552, so that the positioning rotating plate 551 and its corresponding gear 3 536 or gear 4 543 cannot rotate without the action of external force, thereby ensuring that gear 3 536 or gear 4 543 can stably engage with the corresponding rack 1 564 and transmit transmission cooperation.

[0053] See also Figure 9 The sealing mechanism 6 includes a plurality of elastic columns 61 fixedly arranged on the lower side of the detection platform 3 , a lifting component 62 is commonly provided on the plurality of elastic columns 61 , and a sealing component 63 is provided on the lifting component 62 .

[0054] See also Figure 9 and Figure 10The lifting assembly 62 includes a lifting plate 621 that is elastically slidably arranged on multiple elastic columns 61 and moves up and down. A driven column 622 that slides up and down through the detection platform 3 and is press-fitted with the V-groove 423 is fixed on the upper side of the lifting plate 621. A ball is rolled on the upper end of the driven column 622. A rotating sleeve 623 is rotatably arranged on the lifting plate 621. A gear five 624 is fixed on the lower end of the rotating sleeve 623. A rectangular through groove that runs through the upper and lower parts is provided on the rotating sleeve 623 and the gear five 624. A pneumatic cylinder two 625 is fixedly arranged on the right side of the lifting plate 621 through the support five. The telescopic end of the pneumatic cylinder two 625 is fixedly provided with a rack two 626 that moves left and right and is meshed with the gear five 624.

[0055] See also Figure 9 and Figure 10 The sealing assembly 63 includes a rectangular column 631 slidably set in a rectangular through groove, and a pressure plate 632 that slides up and down and penetrates the detection table 3 is fixedly set on the upper end of the rectangular column 631. A threaded column 633 with an inclined upper end and spirally connected to the corresponding internal threaded end of the quick-connect male head 1 is fixedly set on the upper side of the pressure plate 632. A sealing ring 634 is fixedly set on the upper side of the pressure plate 632 and on the outside of the threaded column 633.

[0056] When the rotating disk 421 rotates to convey the quick-connect male connector 1, the upper end of the driven column 622 moves downward under the pressure of the corresponding V-shaped groove 423, and the driven column 622 drives the lifting plate 621 to move downward along the elastic column 61, and the lifting plate 621 drives the rotating sleeve 623 to move downward synchronously, and the pressing plate 632 drives the threaded column 633 and the sealing ring 634 to move downward under the action of its own weight, until the rotating disk 421 conveys the next quick-connect male connector 1 to be tested to the lower side of the quick-connect female connector 2, at which time the upper end of the driven column 622 is just stuck The lifting plate 621 is connected to the V-groove 423 corresponding to the quick-connect male connector 1. Under the action of the elastic column 61, the lifting plate 621 drives the pressure plate 632 and the threaded column 633 to move upward through the rotating sleeve 623. The upper end of the thread on the threaded column 633 then docks with the internal thread at the lower end of the quick-connect male connector 1. When the quick-connect male connector 1 rotates synchronously with the rotating disk 421, the threaded column 633 can move downward to make way under the pressure of the upper end inclined surface and the lower end of the quick-connect male connector 1 to avoid obstructing the rotation of the rotating disk 421 and the corresponding quick-connect male connector 1.

[0057] When the upper end of the thread on the threaded column 633 is connected with the internal thread at the lower end of the quick-connect male head 1 to be tested, the quick-connect female head 2 and the quick-connect male head 1 are first stably installed through the driving component 2 56, and then the pneumatic cylinder 2 625 drives the rack 2 626 to move to the left, and the rack 2 626 then drives the rotating sleeve 623 to rotate through the meshing transmission with the gear 5 624. The rotating sleeve 623 then drives the pressure plate 632 and the threaded column 633 to rotate synchronously through the rectangular column 631, and the threaded column 633 then drives the pressure plate 632 and the threaded column 633 to rotate synchronously. The internal thread spiral docking at the lower end of the quick-connect male connector 1 drives the pressure plate 632 and the sealing ring 634 to move upward until the pressure plate 632 presses the sealing ring 634 to stably seal the lower end of the quick-connect male connector 1. The above-mentioned operation method can automatically and stably seal the internal thread end of the quick-connect male connector 1, thereby not only improving the overall sealing speed and efficiency of the quick-connect male connector 1, but also greatly improving the consistency and stability of the overall sealing of the quick-connect male connector 1, thereby ensuring the accuracy of the connection air tightness test results of the quick-connect male connector 1.

[0058] See also Figure 1 and Figure 4 The blanking mechanism 7 includes a blanking port 71 extending vertically through the right side of the testing platform 3 , and a blanking assembly 72 is provided on the lower side of the testing platform 3 and below the blanking port 71 .

[0059] The material discharge assembly 72 includes a pneumatic cylinder 3 721 which is fixed symmetrically on the lower side of the inspection platform 3 through a support 6. A bidirectional material discharge hopper 722 which can move left and right is fixed between the telescopic ends of the front and back symmetrical pneumatic cylinder 3 721 through a plate. The bidirectional material discharge hopper 722 is provided with guide grooves 723 which are symmetrical on the left and right.

[0060] The qualified quick-connect male connector 1 is driven by the rotating disk 421 to rotate and align above the discharge port 71, and the qualified quick-connect male connector 1 then falls into the guide groove 723 on the right side of the two-way discharge hopper 722 through the corresponding positioning groove 422 and the discharge port 71. The guide groove 723 on the right side then guides the qualified quick-connect male connector 1 to the right for discharge. If the quick-connect male connector 1 to be discharged is an unqualified finished product, the two-way discharge hopper 722 is driven to move to the right by the pneumatic cylinder 3 721 until the left side of the two-way discharge hopper 722 is filled with the qualified quick-connect male connector 1. The guide groove 723 on the side is aligned with the discharge port 71. At this time, the unqualified quick-connect male connector 1 discharged through the discharge port 71 is guided to the left by the guide groove 723 on the left side. The above operation method can not only realize the automatic and stable discharge of the quick-connect male connector 1 that has completed the inspection, but also can separate the unqualified finished products from the qualified finished products, thereby avoiding the unqualified finished products and the qualified finished products from being mixed together, thereby greatly reducing the operational burden of subsequent manual sorting, and further reducing the overall labor cost.
