The button is then conveyed in the button conveying channel 210 and conveyed to the button dislocation groove 221 of the button dislocation plate 220. At this time, the cylinder will drive the button dislocation plate 220 to move, so that the button dislocation groove 221 is dislocated with the tail end of the button conveying channel 210. The button conveying module 230 drives the button suction nozzle 240 to move, and the button suction nozzle 240 absorbs the button in the button dislocation groove 221. Then, the button conveying module 230 drives the button suction nozzle 240 to move, and the button sucked is placed in the assembly groove 111 of the fixture 110.

After reaching the set position, the plastic shell suction nozzle 340 places the plastic shell into the assembly groove 111 of the fixture 110, so that the plastic shell and the press are assembled together, thereby realizing automatic loading of the plastic shell and automatic assembly with the press, and improving the degree of automation and assembly efficiency.

[0025] See also Figures 9 to 13 In order to realize automatic loading and assembly of the sealing cap, the sealing cap loading mechanism 400 in this embodiment includes a sealing cap conveying channel 410, a swing unit 420, a sealing cap transporting module 430, a sleeve unit 440 and a first lifting cylinder 450. The swing unit 420 is located at the tail end of the sealing cap conveying channel 410. The sealing cap transporting module 430 is provided with a sealing cap suction nozzle 460 and a transfer unit 470. The first lifting cylinder 450 acts on the push-lock ejector block 112 to lift the push-lock ejector block 112.

The sealing caps are conveyed in the sealing cap conveying channel 410 and conveyed to the swing unit 420. The swing unit 420 swings the sealing caps at a set angle, and then the sealing cap conveying module 430 drives the sealing cap suction nozzle 460 to absorb the sealing caps on the swing unit 420. After absorption, the sealing cap conveying module 430 drives the sealing cap suction nozzle 460 to place the absorbed sealing caps on the sleeve unit 440. At the same time, the sealing cap conveying module 430 drives the adapter unit 470 to adjust the sealing caps on the sleeve unit 440. The cap is transferred, and then the sealing cap transporting module 430 drives the transfer unit 440 to move toward the jig 110, and the transfer unit 440 puts the sealing cap onto the press stop, and when putting it into place, the first lifting cylinder 450 will lift the bottom of the press stop, so as to facilitate the transfer unit 440 to put the sealing cap onto the press stop, and finally, the sealing cap transporting module 430 drives the sealing cap nozzle 460 to move back and forth between the swing unit 420 and the sleeve unit 440, and drives the transfer unit 470 to move back and forth between the sleeve unit 440 and the jig 110, so as to realize the transfer of the sealing cap, and in this cycle, realize the automatic loading and automatic assembly of the sealing cap, thereby improving the assembly efficiency.

[0026] To ensure automatic loading of the sealing caps, the swing unit 420 in this embodiment includes a swing cylinder 421 and a swing plate 422. The middle portion of the swing plate 422 is rotatably connected to the sealing cap delivery channel 410. One end of the swing plate 422 is connected to the swing cylinder 421, and the other end is provided with a swing groove 423. The swing cylinder 421 drives the swing plate 422 to swing, thereby causing the swing groove 423 to communicate with or be misaligned with the rear end of the sealing cap delivery channel 410. In the initial state, the swing groove 423 of the swing plate 422 is connected to the rear end of the sealing cap delivery channel 410. When the sealing cap is delivered to the swing groove 423, the swing cylinder 421 is operated, driving the swing plate 422 to rotate about its middle portion, thereby causing the swing groove 423 to be misaligned with the rear end of the sealing cap delivery channel 410. This facilitates the sealing cap suction nozzle 460 to suck the sealing cap in the swing groove 423, ensuring automatic loading of the sealing cap.

[0027] See also Figures 11 to 13 In this embodiment, in order to put the sealing cap on the button, the sleeve unit 440 includes a sleeve seat 441, a sleeve needle 442, a sleeve lifting cylinder 443 and a sleeve clamping cylinder 444. The sleeve needle 442 passes through the sleeve seat 441 and is connected to a sleeve driving cylinder 445. The sleeve driving cylinder 445 drives the sleeve needle 442 to move along the sleeve seat 441, and the upper part of the sleeve needle 442 has a needle head 442a. The sleeve lifting cylinder 443 is set on one side of the sleeve seat 441, and the sleeve clamping cylinder 444 is connected to the sleeve. It is connected to the lifting cylinder 443 and cooperates with the sleeve needle 442; at the same time, the adapter unit 470 includes an adapter column 471, an adapter drive cylinder 472 and an adapter sleeve 473. The adapter column 471 and the adapter drive cylinder 472 are respectively installed on the sealing cap transport module 430, and the adapter sleeve 473 passes through the adapter column 471 and is connected to the adapter drive cylinder 472. The adapter drive cylinder 472 drives the adapter sleeve 473 to move along the adapter column 471, and the outer diameter of the adapter sleeve 473 is the same as the outer diameter of the sleeve needle 442.

[0028] 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, and then 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 is sleeved, the sleeve lifting The cylinder 443 will drive the sleeve clamping cylinder 444 to move upward. When the sleeve clamping cylinder 444 moves upward, it will slide the clamped sealing cap upward 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 sleeved onto the adapter sleeve 473, the sealing cap conveying 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 moving the adapter post 471 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 where 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.

[0029] See also Figure 16After the sealing cap is put onto the press-lock, it is necessary to clamp the sealing cap to the corresponding position of the press-lock. Therefore, the sealing cap needs to be press-fitted. Therefore, the press-fitting mechanism 700 in this embodiment includes a press-fitting cylinder 710 and a third ejecting cylinder 720. The press-fitting cylinder 710 is connected to a press-fitting head 730. The press-fitting cylinder 710 drives the press-fitting head 730 to move toward the jig 110. The third ejecting cylinder 720 acts on the press-fitting top block 112 to lift the press-fitting top block 112. When the turntable 100 drives the jig 110 to rotate to the pressing mechanism 700, the third lifting cylinder 720 will lift the push-button top block 112, thereby lifting the push-button, and then the rear pressing cylinder 710 will operate, driving the pressing head 730 to move downward, and the pressing head 730 will act on the top of the sealing cap and press the top of the sealing cap into the clamping groove of the push-button, so as to realize the clamping of the top of the sealing cap and the push-button, realize automated assembly, and improve assembly efficiency.

[0030] See also Figure 14 After the top of the sealing cap is clamped with the press, the bottom end of the sealing cap needs to be riveted to the top of the plastic shell. In order to achieve automatic riveting of the bottom end of the sealing cap and the top end of the plastic shell, the riveting mechanism 500 in this embodiment includes a riveting driving member 510, a hot riveting unit 520 and a second ejecting cylinder 530.

When the turntable 100 drives the jig 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. When the hot riveting unit 520 moves downward, it will also move the riveting head 530 downward, and make the riveting head 530 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, improving the degree of automation and assembly efficiency.

When the turntable 100 drives the jig 110 to rotate to the unloading mechanism 600, the unloading and handling module 610 will drive the unloading clamp 660 to clamp the assembled finished product in the assembly slot 111 of the jig 110, and move it to the good product channel 620 or the defective product channel 630. If the assembled finished product is qualified, the dividing rotary 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 finished product into the good product channel 620, and the good product channel 620 will carry out material collection processing. If the assembled finished product is unqualified, the dividing rotary cylinder 640 drives the dividing plate 650 to rotate to close the good product channel 620. The unloading clamp 660 will put the clamped assembled finished 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 finished products.

[0032] Finally, see Figure 1 and Figure 2 In order to ensure the assembly quality and assembly pass rate, 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 first be inspected by the inspection mechanism 800. The inspection mechanism 800 is a CCD visual inspection. The inspection mechanism 800 can detect whether there are any defects in the appearance of the plastic shell, whether the sealing cap is aligned with the press stud clamp, etc., thereby effectively improving the assembly quality and ensuring the assembly pass rate of the press stud, plastic shell and sealing cap.
