[0024] Reference Figures 1 to 3 The embodiment of the present application provides an automatic riveting machine, including: a machine base 100; a lower die 200, which is arranged on the machine base 100, and the lower die 200 is provided with four support columns 210, and the four support columns 210 correspond to the four riveting holes of the circuit board 600 respectively, and a sleeve 220 is placed on the top of the support column 210; an upper die 300, which is arranged above the lower die 200, and the upper die 300 is provided with a punch 310, and the punch 310 is adapted to the support column 210; a lifting mechanism 400, which is arranged on the machine base 100, and the lifting mechanism 400 is connected to the upper die 300, and the lifting mechanism 400 drives the upper die 300 to descend, so that the punch 310 cooperates with the support column 210 to rivet the sleeve 220 to the circuit board 600.

[0025] When in use, the circuit board 600 is placed above the sleeve 220, so that the top of the sleeve 220 is inserted into the riveting hole of the circuit board 600; then the lifting mechanism 400 drives the upper die 300 to descend, so that the punch 310 cooperates with the support column 210, thereby riveting the sleeve 220 to the circuit board 600. By providing four support columns 210, the punch 310 is adapted to the support column 210, so that multiple sleeves 220 can be riveted at one time, avoiding the imbalance of the sleeve 220, reducing labor intensity, shortening working time, and improving work efficiency.

[0026] Reference Figures 1 to 3 , wherein the lifting mechanism 400 is set as a lifting cylinder, which has a simple structure and stable operation. It can be imagined that the support column 210 is lifted and lowered with a guide mechanism 230, and the sleeve 220 is arranged between the guide mechanisms 230. Since the bottom of the sleeve 220 is a plane, when the sleeve 220 is placed above the support column 210, it is easy for the position of the sleeve 220 to be offset. Therefore, by providing the guide mechanism 230, the position of the sleeve 220 can be limited, thereby improving the quality of the riveting. Specifically, the guide mechanism 230 includes a plurality of guide rods 231, a mounting ring 240 is provided in the middle of the support column 210, and a plurality of guide rods 231 are circumferentially arranged on the mounting ring 240, and the sleeve 220 is located between the guide rods 231. At this time, the sleeve 220 is restricted by the guide rods 231 all around, thereby preventing the sleeve 220 from sliding off the support column 210, improving the stability of the work, and improving the product quality. It can be imagined that the guide rod 231 is lifted and arranged on the mounting ring 240, and the top of the guide rod 231 abuts against the circuit board 600, so as to increase the contact area and ensure the stability of the circuit board 600. By lifting and setting the guide rod 231 on the mounting ring 240, when the punch 310 lowers the riveting sleeve 220, the position of the circuit board 600 will be slightly lowered. At this time, the guide rod 231 is lowered with the circuit board 600 to avoid damage to the circuit board 600 and improve product quality. Furthermore, a limit block 232 is provided at the bottom end of the guide rod 231, and a reset spring 233 is provided between the limit block 232 and the mounting ring 240. By providing the reset spring 233, the guide rod 231 can be automatically reset, so as to facilitate the riveting of the next circuit board 600 and improve work efficiency.

[0027] Reference Figure 1 to Figure 2In this embodiment, the lower die 200 is horizontally slidably arranged on the base 100, so that the lower die 200 slides away from the upper die 300, thereby facilitating the loading and unloading of the sleeve 220 and the circuit board 600 and improving safety. Specifically, the base 100 is provided with a sliding cylinder 250, and the sliding cylinder 250 is connected to the lower die 200. The sliding cylinder 250 drives the lower die 200 to slide, and the structure is simple and the operation is stable. It can be imagined that the lower die 200 is provided with a plurality of mounting holes 260 arranged in an array, and the support column 210 is penetrated in the mounting hole 260. By providing a plurality of mounting holes 260, the position of the support column 210 can be adjusted, and accordingly, the position of the punch 310 should also be adjustable, so that it can adapt to circuit boards 600 of different specifications and expand the scope of application. It is easy to understand that the mounting hole 260 is set as a bar hole, and the plurality of mounting holes 260 are connected through the connecting hole, and the support column 210 is slidably set in the mounting hole 260. By adopting the above structure, it is easy to adjust the position of the support column 210, and the structure is simple and the operation is easy.

[0028] Reference Figure 1 In some embodiments, the automatic riveting machine further includes a sensor 510 and a controller 520. The sensor 510 is disposed on the machine base 100. The sensor 510 is used to sense whether the circuit board 600 exists. The sensor 510 is electrically connected to the lifting mechanism 400. The controller 520 is electrically connected to the sensor 510 and the lifting mechanism 400. When working, the circuit board 600 is placed above the sleeve 220, and the top of the sleeve 220 is penetrated through the riveting hole on the circuit board 600. At this time, the sensor 510 senses the existence of the circuit board 600 and sends a signal to the controller 520, which is recorded and stored by the controller 520. At the same time, the sensor 510 also feeds back the signal to the lifting mechanism 400, so that the lifting mechanism 400 drives the lower die 200 to descend, so that the punch 310 cooperates with the support column 210 to rivet the sleeve 220 to the circuit board 600, thereby realizing automatic riveting of the sleeve 220 and improving work efficiency. It is conceivable that the base 100 is provided with a fixing plate 110, the fixing plate 110 is vertically provided with an elongated hole 120, and the sensor 510 is passed through the elongated hole 120. By adopting the above mechanism, it is convenient to adjust the position of the sensor 510, with a simple structure and easy operation.
