[0011] Furthermore, the female buckle conveying unit includes a female buckle conveying base frame; the female buckle conveying base frame is installed on the outer wall of the main frame away from the vertical mounting plate; a female buckle riveting mechanism is movably engaged at the top of the female buckle conveying base frame.

[0012] Furthermore, the female buckle riveting mechanism includes a female buckle riveting base and an electric push rod. The female buckle riveting base is movably engaged with the top of the female buckle conveying base frame. A female buckle conveying cavity is opened inside the female buckle riveting base. A lifting rod mounting cavity is provided below the female buckle conveying cavity. The electric push rod is installed in the lifting rod mounting cavity.

[0016] The beneficial effects of this invention are:

[0017] 1. The punching head and the sub-clamping head are simultaneously installed on the bottom of the electric turntable, on the same plane. When the punching head descends to punch the belt, the sub-clamping head is pulled in by its descent. Then, the electric turntable rotates the sub-clamping head to directly above the punching point, and the riveting work is performed directly. This achieves integrated punching and riveting, eliminating the need for an additional punching process and manual adjustment, thus shortening working time and improving work efficiency.

[0018] 2. The sub-buckle is conveyed to the top groove via the second conveyor belt. An infrared sensor detects it first, then the control unit activates the cylinder, allowing the abutment rod to contact the sub-buckle. This allows the fan-shaped ring support and the abutment rod to limit the sub-buckle from both front and rear directions. The sliding connection between the slide plate and the guide rail then transports the sub-buckle into the sub-buckle limiting groove, ready for subsequent riveting. This achieves automatic sub-buckle feeding, thus improving workflow smoothness.

[0019] 3. After the punching process is completed, the first vibratory feeder is activated, and the first conveyor belt transports the female buckle from the first vibratory feeder to the female buckle limiting groove, where it contacts the pressure sensor. The pressure sensor then sends a signal to the control unit, which in turn controls the electric push rod to raise the female buckle limiting seat into the female buckle riveting groove. Then, the punching hydraulic cylinder is activated to rivet the female buckle onto the belt from both above and below. This automates the female buckle feeding process, thereby reducing labor intensity.

[0020] 4. By rotating the first threaded rod, the belt limiting top plate is fixed to the top of the belt. Then, the third threaded rod is rotated. Since the threads of the third and second threaded rods are set in opposite directions, when the third threaded rod is rotated, both sets of belt limiting side plates will move simultaneously towards the middle of the belt and eventually abut against the belt from both sides, thus fixing the belt. This not only improves the stability of the punching operation but also allows the belt fixing mechanism to fix belts of any size and thickness, improving the overall compatibility of the device.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a punching and riveting machine. It includes a main frame 100, a first vibratory feeder 200, a second vibratory feeder 300, a female buckle conveying unit 400, a riveting unit 500, and a female buckle conveying unit 600. For example,... Figure 1 and Figure 2 As shown, the first vibratory plate 200 and the second vibratory plate 300 are symmetrically installed on the outer walls of both sides of the main frame 100.

[0037] A first conveyor belt 210 is fixedly installed on the output end of the first vibratory plate 200, and a second conveyor belt 310 is fixedly installed on the output end of the second vibratory plate 300.

[0038] The sub-button conveying unit 400 is fixedly installed on the top of the main frame 100, and the input end of the sub-button conveying unit 400 is connected to the end of the second conveyor belt 310 away from the second vibrating plate 300.

[0039] The female buckle conveying unit 600 is fixedly installed on the outer wall of the main frame 100 on one side perpendicular to the first vibrating plate 200. The input end of the female buckle conveying unit 600 is connected to the end of the first conveyor belt 210 away from the first vibrating plate 200.

[0040] The riveting unit 500 is fixedly installed on the top of the main frame 100, and the output end of the riveting unit 500 is movably attached to the output ends of the male buckle conveying unit 400 and the female buckle conveying unit 600, respectively.

[0041] A control unit 700 is fixedly installed on the main frame 100. The control unit 700 is electrically connected to the first vibratory plate 200, the second vibratory plate 300, the female buckle conveying unit 400, the riveting unit 500, and the female buckle conveying unit 600.

[0042] The buckle conveying unit 400 includes a buckle conveying seat 410, a sliding plate 450, a support ring 460, and a front abutment rod 470. For example, as shown... Figure 3 and Figure 4As shown, the top of the sub-button conveyor 410 has a top groove 420, and the end of the top groove 420 near the female button conveyor unit 600 is an open structure. A feed inlet 421 is provided on the side wall of the top groove 420 near the second vibrating plate 300, and the feed inlet 421 communicates with the second conveyor belt 310. A sub-button limiting groove 430 is provided on the side of the top groove 420 near the opening. A slide rail 440 is provided on the side of the sub-button conveyor 410 away from the second vibrating plate 300, and a sliding plate 450 is slidably connected to the slide rail 440. A cylinder is fixedly installed on the sliding plate 450. A support ring mounting plate 451 is installed on the sliding plate 450, and the other end of the support ring mounting plate 451 extends directly above the sub-button conveyor 410. The ring support portion 460 includes a ring support connecting rod 461 and a ring support body 462. The ring support connecting rod 461 is installed at the bottom of the ring support mounting plate 451, and the ring support body 462 is installed at the bottom of the ring support connecting rod 461. The ring support body 462 has a fan-shaped annular structure, and the bottom of the ring support body 462 is attached to the bottom inner wall of the top groove 420. A stop rod rotating rod 452 is provided on the side of the ring support mounting plate 451 near the opening of the top groove 420. The front stop rod 470 includes a pneumatic rotating rod 471 and a stop rod body 472. The pneumatic rotating rod 471 is rotatably connected to the stop rod rotating rod 452, and the other end of the pneumatic rotating rod 471 is fixedly connected to the stop rod body 472. The pneumatic rotating rod 471 communicates with the cylinder. The other end of the stop rod body 472 is movably attached to the bottom inner wall of the top groove 420. The angle between the abutment body 472 and the bottom inner wall of the top groove 420 is greater than the angle between the pneumatic rotating rod 471 and the top inner wall of the top groove 420. A far-infrared sensor 480 is fixedly installed on the inner wall of the top groove 420 away from the feed inlet 421.

[0043] The first vibratory feeder 200 and the second vibratory feeder 300 are activated respectively. The second vibratory feeder 300 conveys the sub-buckle to the second conveyor belt 310, and then the second conveyor belt 310 conveys it to the top groove 420 through the feed port 421. It then adheres to the fan-shaped ring support body 462. At the same time, the far-infrared sensor 480 detects the presence of the sub-buckle and sends a signal to the control unit 700. The control unit 700 then activates the cylinder, which drives the pneumatic rotating rod 471 and the abutment rod body 472 to rotate, so that the abutment rod body 472 abuts against the sub-buckle. Then the power system of the slide rail 440 is activated, so that the slide plate 450 drives the ring support part 460 and the front abutment rod 470 to move as a whole towards the sub-buckle limiting groove 430. Finally, the sub-buckle is conveyed into the sub-buckle limiting groove 430.

[0044] The sub-button is conveyed to the top groove 420 via the second conveyor belt 310 and detected by the far-infrared sensor 480. Then, the cylinder is activated by the control unit 700, allowing the abutment body 472 to abut against the sub-button. This allows the fan-shaped ring support body 462 and the abutment body 472 to limit the sub-button from both front and rear directions. The sliding connection between the slide plate 450 and the slide rail 440 then transports the sub-button to the sub-button limiting groove 430, ready for subsequent riveting. This achieves automatic sub-button feeding, reducing labor intensity and thus improving work flow.

[0045] The riveting unit 500 includes a vertical mounting plate 510, a punching hydraulic cylinder 530, and an electric turntable 550. For example, Figure 5 and Figure 6 As shown, the vertical mounting plate 510 is fixedly installed on the top edge of the main frame 100 on the side away from the female buckle conveying unit 600. A top plate 520 is installed on the top wall of the vertical mounting plate 510 near the female buckle conveying unit 600. The punching hydraulic cylinder 530 is mounted on the top plate 520, and a turntable connecting rod 540 is drivenly connected to the output end of the punching hydraulic cylinder 530. An electric turntable 550 is installed at the bottom of the turntable connecting rod 540. A female buckle rivet joint 560 and a punching head 570 are installed at the bottom of the electric turntable 550. The distance from the female buckle rivet joint 560 to the punching head 570 is the same as the distance from the female buckle limiting groove 430 to the output end of the female buckle conveying unit 600.

[0046] First, the belt is secured by the female buckle conveyor unit 600, and then the male buckle is conveyed to the male buckle limiting groove 430 by the male buckle conveyor unit 400. Next, the position of the punching head 570 is adjusted so that it is directly above the belt. Since the distance between the male buckle limiting groove 430 and the belt is the same as the distance between the male buckle rivet joint 560 and the punching head 570, when the punching head 570 is lowered by the punching hydraulic cylinder 530 to punch the belt, the male buckle rivet joint 560 also lowers simultaneously, attracting the male buckle in the male buckle limiting groove 430, allowing the punching operation and the male buckle loading to be performed simultaneously. After the punching operation is completed, the punching head 570 and the male buckle rivet joint 560 rise, and the electric turntable 550 rotates the male buckle rivet joint 560 to directly above the punching point.

[0047] The female buckle in the first vibratory feeder 200 is then transported to the female buckle conveying unit 600 via the first conveyor belt 210, and finally delivered directly below the punching point, so that the male buckle and the female buckle are on the same vertical line. Then, the punching hydraulic cylinder 530 is activated, which drives the male buckle on the male buckle riveting joint 560 to descend, so that the male buckle and the female buckle are riveted to the belt from both above and below. This achieves integrated punching and riveting, eliminating the need for an additional punching process, shortening working time, and improving work efficiency.

[0048] The female buckle conveying unit 600 includes a female buckle conveying base frame 610, a female buckle riveting mechanism 620, and a female buckle limiting part 640. For example, Figure 7 and Figure 8 As shown, the female buckle conveying base frame 610 is fixedly installed on the outer wall of the main frame 100 away from the vertical mounting plate 510. The female buckle riveting mechanism 620 includes a female buckle riveting base 621 and an electric push rod 624. The female buckle riveting base 621 is movably engaged with the top of the female buckle conveying base frame 610. A female buckle conveying cavity 622 is formed inside the female buckle riveting base 621. A lifting rod mounting cavity 623 is provided below the female buckle conveying cavity 622. The electric push rod 624 is installed in the lifting rod mounting cavity 623, and the output end of the electric push rod 624 passes through the female buckle conveying cavity 622 and is fixedly connected to the female buckle limiting part 640. A female buckle riveting groove 630 is formed at the top of the female buckle conveying cavity 622. The distance from the female buckle riveting groove 630 to the male buckle limiting groove 430 is the same as the distance between the male buckle riveting head 560 and the punch head 570. The female buckle limiting part 640 can be inserted into the female buckle riveting groove 630 through the electric push rod 624. The end of the first conveyor belt 210 away from the first vibrating plate 200 is inserted into the female buckle conveying cavity 622 and a female buckle guide plate 211 is fixedly installed thereon. The other end of the female buckle guide plate 211 is connected to the female buckle limiting part 640.

[0049] The female buckle limiting part 640 includes a female buckle limiting seat 641. For example, as shown... Figure 9 As shown, the female buckle limiting seat 641 is installed on the output end of the electric push rod 624. The top of the female buckle limiting seat 641 is provided with a female buckle limiting groove 642, and a pressure sensor 643 is installed in the female buckle limiting groove 642.

[0050] After the punching operation is completed, the first vibratory feeder 200 is activated, and the first conveyor belt 210 transports the female buckle from the first vibratory feeder 200 to the female buckle limiting groove 642, where it contacts the pressure sensor 643. The pressure sensor 643 then sends a signal to the control unit 700, which in turn controls the electric push rod 624 to raise the female buckle limiting seat 641 into the female buckle riveting groove 630. Then, the punching hydraulic cylinder 530 is activated to rivet the female buckle onto the belt from both above and below. This automates the female buckle feeding process and reduces labor intensity.

[0051] Two sets of belt fixing mechanisms 650 are symmetrically installed on both sides of the female buckle riveting groove 630. Each belt fixing mechanism 650 includes a belt limiting seat 651, a first threaded rod 653, and a second threaded rod 655. For example,... Figure 10 and Figure 11 As shown, the belt limiting seat 651 has a belt through hole 660, both ends of which are open structures. A threaded sleeve 652 is provided at the top of the belt limiting seat 651. A first threaded rod 653 is threadedly connected to the threaded sleeve 652, with one end of the first threaded rod 653 penetrating into the belt through hole 660 and fixedly mounted with a belt limiting top plate 654. A belt mounting cavity is provided below the belt through hole 660. One end of the second threaded rod 655 is rotatably connected to the inner wall of the belt mounting cavity, and the other end is fixedly mounted with a threaded rod isolation block 670. A third threaded rod 656 is fixedly mounted at the other end of the threaded rod isolation block 670. The third threaded rod 656 is rotatably connected to the inner wall of the belt mounting cavity, and the other end extends to the outside of the belt limiting seat 651. The thread directions of the second threaded rod 655 and the third threaded rod 656 are opposite. Both the second threaded rod 655 and the third threaded rod 656 have a set of sliding grooves 661 on their upper surfaces, and a set of sliders 662 are slidably connected in each of the two sets of sliding grooves 661. One end of each set of sliders 662 is threaded to the second threaded rod 655 and the third threaded rod 656, respectively, and the other end of each set of sliders 662 passes through the belt through hole 660, and a set of belt limiting side plates 663 are fixedly installed in each of them.

[0052] First, the belt is inserted through the belt through hole 660 on one side and exited through the belt through hole 660 on the other side, so that the rivet point is directly above the rivet groove 630 of the female buckle. Then, the belt is fixed by the belt limiting top plate 654 and the two sets of belt limiting side plates 663 respectively.

[0053] Rotating the first threaded rod 653 fixes the belt-limiting top plate 654 to the top of the belt. Then, rotating the third threaded rod 656 causes both sets of belt-limiting side plates 663 to move simultaneously towards the middle of the belt, ultimately abutting against it from both sides and securing the belt. This not only improves the stability of the punching operation but also allows the belt fixing mechanism to secure belts of any size and thickness, enhancing the overall compatibility of the device.
