[0054] When the sealing cap is assembled, the sealing cap transporting module 430 drives the sealing cap suction nozzle 460 to suck the sealing cap in the swing groove 423, and then drives it to move through the sealing cap transporting module 430. After moving to the set position, the sleeve driving cylinder 445 drives the sleeve needle 442 to move upward, and the sealing cap suction nozzle 460 places the sucked sealing cap directly on the needle head 442a of the sleeve needle 442. After that, the sleeve lifting cylinder 443 drives the sleeve clamping cylinder 444 to move, and after moving to the set position, the sleeve clamping cylinder 444 clamps the sealing cap on the needle head 442a. After clamping, the sleeve lifting cylinder 443 drives the sleeve lifting cylinder 443 to move. The sleeve clamping cylinder 444 moves downward, and the sleeve clamping cylinder 444 slides downward with the clamped sealing cap, so that the sealing cap slides to the lower part of the sleeve needle 442; when the sealing cap is sleeved to the lower part of the sleeve needle 442, the sealing cap transporting module 430 drives the sealing cap suction nozzle 460 to move to the swing unit 420, and the adapter unit 470 is moved to the sleeve unit 440. At this time, the adapter driving cylinder 472 drives the adapter sleeve 473 to move downward, and the needle head 422a of the sleeve needle 422 is inserted into the adapter sleeve 473, so that the sleeve needle 422 and the adapter sleeve 473 are sleeved with each other. After the sleeve connection, the sleeve lifting and lowering The cylinder 443 will drive the sleeve clamping cylinder 444 to move upward. When the sleeve clamping cylinder 444 moves upward, it will slide upward with the clamped sealing cap and slide onto the adapter sleeve 473. Since the outer diameter of the adapter sleeve 473 is the same as the outer diameter of the lower part of the sleeve needle 442, the sealing cap can slide smoothly onto the adapter sleeve 473. After the sealing cap is inserted into the adapter sleeve 473, the sealing cap transporting module 430 drives the adapter unit 470 to move toward the fixture 110. When it reaches the top of the press, the first ejecting cylinder 450 is pushed upward to lift the press block 112, thereby lifting the press, and at the same time, the sealing cap is transported. The module 430 drives the adapter unit 470 to move downward as a whole, thereby causing the adapter post 471 to move downward, and the adapter drive cylinder 472 drives the adapter sleeve 473 to move upward. During the upward movement of the adapter sleeve 473, the sealing cap will be blocked by the bottom of the adapter post 471, thereby forming a situation in which the adapter post 471 moves downward while the adapter sleeve 473 moves upward, until the bottom of the adapter post 471 abuts against the top of the button, and after the adapter sleeve 473 is completely pulled upward, the sealing cap will be directly rotated onto the button, ultimately realizing automatic loading of the sealing cap and automatic assembly with the button, thereby improving the degree of automation and assembly efficiency.

When the turntable 100 drives the fixture 110 to rotate to the riveting mechanism 500, the second ejecting cylinder 530 will also drive the push-lock ejector block 112 to lift upward, thereby lifting the push-lock, and the riveting driving member 510 will drive the hot riveting unit 520 to move downward. The hot riveting unit 520 will move downward with the riveting head 530 while moving downward, and the riveting head 530 will act on the bottom end of the sealing cap, so that the bottom end of the sealing cap and the top of the plastic shell are hot-riveted, thereby realizing automatic assembly of the sealing cap and the plastic shell, and improving the degree of automation and assembly efficiency.

[0057] See also Fig.15After the assembly of the button, the plastic shell and the sealing cap is completed, they need to be automatically unloaded. Therefore, the unloading mechanism 600 in this embodiment includes an unloading and transporting module 610, a good product channel 620, a defective product channel 630, a dividing rotary cylinder 640 and a dividing plate 650. The unloading and transporting module 610 is provided with an unloading clamp 660. The dividing plate 650 is located between the good product channel 620 and the defective product channel 630 and is connected to the dividing rotary cylinder 640. The dividing rotary cylinder 640 drives the dividing plate 650 to close the good product channel 620 or the defective product channel 630. When the turntable 100 drives the fixture 110 to rotate to the unloading mechanism 600, the unloading and handling module 610 will drive the unloading clamp 660 to clamp the finished assembly in the assembly slot 111 of the fixture 110, and move it to the good product channel 620 or the defective product channel 630. If the assembled product is qualified, the dividing rotating cylinder 640 drives the dividing plate 650 to rotate to close the defective product channel 630. At this time, the unloading clamp 660 will put the clamped assembled product into the good product channel 620, and the good product channel 620 will carry out material collection processing. If the assembled product is unqualified, the dividing rotating cylinder 640 drives the dividing plate 650 to rotate to close the good product channel 620, and the unloading clamp 660 will put the clamped assembled product into the defective product channel 630, and the defective product channel 630 will carry out material collection processing, thereby realizing automatic sorting and unloading of the assembled products.

[0058] Finally, see Figure 1 and Figure 2 In order to ensure the assembly quality and the qualified rate of assembly, in this embodiment, before the riveting mechanism 500 performs hot riveting on the sealing cap and the plastic shell, the semi-finished product in the assembly groove 111 of the fixture 110 will be inspected by the detection mechanism 800. The detection mechanism 800 is a CCD visual inspection. The detection mechanism 800 is used to detect whether there are any defects in the appearance of the plastic shell, whether the sealing cap is in contact with the button clamp, etc., thereby effectively improving the assembly quality and ensuring the qualified rate of the button, the plastic shell and the sealing cap.
