The shape of the dripping bucket groove 6391 fits the end of the dripping bucket's guide tube.When the dripping bucket is placed on the fixture 15, the guide tube end of the dripping bucket protrudes from the bottom of the fixture 15. The dripping bucket lifting cylinder 632 drives the dripping bucket rotation motor 6313 and the dripping bucket rotation electric cylinder 637 to move upward. The dripping bucket rotation electric cylinder 637 drives the dripping bucket rotation clamping finger 639 to clamp the guide tube end of the dripping bucket. The motor shaft of the dripping bucket rotation motor 6313 drives the drive gear 6314 to rotate, thereby the auxiliary gear 6316, the driven gear 6318 and the clamping finger rotation shaft 6317 all start to rotate. The clamping finger rotation shaft 6317 drives the dripping bucket rotation clamping finger 639 and the dripping bucket inside the fixture 15 to rotate.

[0050] In the above technical solution: the drip dispensing mechanism 62 includes a dispensing base 621 and a dispensing moving cylinder 622. The dispensing base 621 is fixed on the support frame 10. A dispensing column 623 is fixed on the dispensing base 621. A dispensing top block 624 is fixed on the top of the dispensing column 623. A dispensing support plate 625 is fixed on the top of the dispensing top block 624. Figure 15 As shown, an adhesive filling cylinder fixing plate 627 is installed on the adhesive filling support plate 625, and an adhesive filling moving cylinder 622 is installed on the adhesive filling cylinder fixing plate 627. In this embodiment, there are four sets of adhesive filling moving cylinders 622. An L-shaped adhesive filling moving slider 628 is provided on the adhesive filling moving cylinder 622, and the adhesive filling moving cylinder 622 drives the adhesive filling moving slider 628 to move. An adhesive filling translation connecting block 629 is installed on the horizontal part of the L-shaped adhesive filling moving slider 628, and a glue gun 6210 is installed on the adhesive filling translation connecting block 629. A glue tank 6211 is provided on the glue gun 6210, and the glue tank 6211 stores glue. The glue gun 6210 sprays the glue from the glue tank 6211. A glue manifold 626 is also fixed to the side of the adhesive filling top block 624.

[0051] The working process of this invention is as follows: The puncture device feeding device 2 feeds the puncture device into the puncture hole 1512 of the fixture 15. The fixture 15 moves the puncture device to the nut feeding device 3, which feeds the nut and places it on the puncture device. The fixture 15 moves the puncture device and nut to the sealing ring feeding device 4, which feeds the sealing ring and places it on the puncture device. The fixture 15 moves the puncture device, nut, and sealing ring to the dripping bucket feeding device 5, which feeds the dripping bucket into the rotating sleeve 1533 of the fixture 15. The fixture 15 moves the puncture device, nut, sealing ring, and dripping bucket to their respective positions for assembly. The drip chamber lifting cylinder 632 of the drip chamber rotating assembly 63 drives the drip chamber rotating electric cylinder 637 to move upward until the end of the guide tube of the drip chamber protruding from the bottom of the fixture 15 is positioned between the two drip chamber rotating fingers 639. The drip chamber rotating electric cylinder 637 drives the drip chamber rotating fingers 639 to clamp the end of the guide tube of the drip chamber. The drip chamber rotating motor 6313 drives the drip chamber rotating fingers 639 and the drip chamber inside the fixture 15 to rotate. The glue-adding moving cylinder 622 drives the glue gun 6210 to move closer to the drip chamber rotating assembly 63. The glue gun 6210 sprays glue, which falls onto the piercing end of the drip chamber. The rotation of the drip chamber makes the glue spread more evenly. When the piercing end of the drip chamber is covered with a full circle of glue, the glue gun 6210 stops spraying glue, the glue-adding moving cylinder 622 drives the glue gun 6210 to move away from the drip chamber rotating assembly 63, and the drip chamber rotating motor 6313 stops running. The puncture device gripping mechanism 61 grips the puncture device, which already has a nut and sealing ring installed on the fixture 15, and moves the puncture device directly above the drip chamber. The lifting assembly 617 then lowers the puncture device, and the connecting end of the puncture device gradually enters the puncture device end of the drip chamber until the puncture device step abuts against the end of the drip chamber. Adhesive completes the connection between the puncture device and the drip chamber. The drip chamber rotating cylinder 637 rotates the drip chamber, and the clamping finger 639 releases the guide tube end of the drip chamber.

[0052] Next, fixture 15 moves the assembled piercing device and dripping bucket to vision inspection device 65. Vision inspection device 65 detects and judges whether the assembly between the dripping bucket, piercing device, sealing ring, and nut is correct. When the system determines that the assembly between the dripping bucket, piercing device, sealing ring, and nut is incorrect, fixture 15 moves the incorrectly assembled defective product to defective product unloading device 9 for unloading. When the system determines that the assembly between the dripping bucket, piercing device, sealing ring, and nut is correct, fixture 15 moves to sheath feeding device 7, which feeds the sheath and places it on the piercing device. At this point, the dripping bucket assembly is complete. Fixture 15 then moves the dripping bucket assembly to finished product unloading device 8 for unloading.
