When the adjustment opening 1596 needs to be reduced, the bolt is positioned with a screwdriver, and the nut is rotated toward the head of the bolt until the adjustment opening 1596 is reduced to the required extent.

[0030] In the above technical solutions: such as Figure 4 , 5 As shown in Figure 8, Figure 5 for Figure 4 In the cross-sectional view along section line A-A, the lower jig block 152 has sequentially formed first guide post holes 1521, second guide post holes 1522, third guide post holes 1523, fourth guide post holes 1524, and fifth guide post holes 1525. First guide posts 1509 are installed in the first guide post holes 1521, third guide post holes 1523, and fifth guide post holes 1525, and second guide posts 154 are installed in the second guide post holes 1522 and fourth guide post holes 1524. A supporting top plate 158 is provided below the lower jig block 152, and the bottoms of the first guide posts 1509 and second guide posts 154 are fixed to the supporting top plate 158. Figure 8 As shown, the bottom of the first guide post hole 1521, the third guide post hole 1523, and the fifth guide post hole 1525 is provided with a cylindrical groove 1526, which facilitates the assembly of the first guide post 1509. The top of the second guide post hole 1522 and the fourth guide post hole 1524 is provided with a third limiting ring 1527, as shown... Figure 5 , 8As shown, an oil-free bushing 155 is fitted on the second guide post 154. The top of the oil-free bushing 155 abuts against the third limiting ring 1527. A fixture pad 156 is provided at the bottom of the oil-free bushing 155. A support spring 157 is fitted at the bottom of the second guide post 154. One end of the support spring 157 abuts against the fixture pad 156, and the other end abuts against the support top plate 158.

[0031] In the above technical solutions: such as Figure 4 , 7 As shown in Figure 9, the top of the lower fixture block 152 is provided with more than one first protrusion 1528, and a groove 1529 is formed between two adjacent first protrusions 1528. The upper fixture block 151 is located on top of the lower fixture block 152, and the side of the upper fixture block 151 is provided with second protrusions 1511 corresponding to the grooves 1529. The second protrusions 1511 are located in the grooves 1529. The upper fixture block 151 is provided with a plurality of puncture holes 1512. One end of the puncture device is responsible for puncture (hereinafter referred to as the puncture end), and the other end is connected to the drip chamber (hereinafter referred to as the connection end). A puncture device step is provided between the puncture end and the connection end of the puncture device. After the puncture device is inserted into the puncture hole 1512, the connection part of the puncture device is set downward and in contact with the top of the lower fixture block 152. In this embodiment, four puncture holes 1512 are provided.

[0032] 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 the assembly device 6 for assembly. The assembly device 6 rotates the dripping bucket inside the fixture 15, while simultaneously applying glue to the puncture end of the dripping bucket. The rotation of the dripping bucket ensures that the glue is applied more evenly. After the puncture end of the drip chamber is covered with a full circle of glue, the assembly device 6 stops spraying glue and moves the puncture device, which already has a nut and a sealing ring installed on the fixture 15, to directly above the drip chamber. The assembly device 6 then lowers the puncture device, and the connecting end of the puncture device gradually enters the puncture end of the drip chamber until the step of the puncture device abuts against the end of the drip chamber, and the glue completes the connection between the puncture device and the drip chamber.

[0033] 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.

[0034] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should fall within the protection scope of the present invention.
