In electronic equipment, a large number of tiny parts need to be precisely riveted to ensure the reliability and miniaturization of the equipment. The core principle of riveting technology is to use pressure to cause the rivet to undergo plastic deformation under the action of the mold, thereby achieving a fastened connection. The prototype of this technology uses a simple mechanical pressure device to apply vertical pressure to the rivet, causing one end of the rivet to deform and fill the hole in the connector. Compared with traditional riveting, it can more accurately control the deformation process of the rivet.

[0037] The remaining structures are the same as those of Example 1.

[0038] Example 3

[0039] Reference Figure 1 , 6 , which is the third embodiment of the present invention, which is different from the second embodiment in that: a rectangular mounting tray 28 is also provided at the vertical surface of the mold operation table 1, an electromagnetic inductor 29 is provided at the upper surface of the rectangular mounting tray 28, an operational amplifier 30 is also provided at the upper surface of the rectangular mounting tray 28, and the operational amplifier 30 and the electromagnetic inductor 29 are connected through a data transmission line 31, an electronic metering device 32 is also provided at the vertical surface of the mold operation table 1, and a battery 33 is also provided at the upper surface of the electronic metering device 32, and a circular hole is opened through the upper surface of the rectangular mounting tray 28, and the electromagnetic inductor 29 is based on the law of electromagnetic induction.

It has two input terminals (an inverting input terminal and a non-inverting input terminal) and an output terminal. Various amplifiers can be constructed by external resistors, capacitors and other components. In sensor signal processing, such as temperature sensors, pressure sensors, etc., operational amplifiers can amplify the weak electrical signals output by the sensors for subsequent analog-to-digital conversion and processing.

During the falling process of the parts, the electromagnetic sensor 29 will change the magnetic field around the sensor when the metal object approaches, thereby generating an induced current, and finally generating an electrical signal surface, which is then transmitted to the operational amplifier 30 through the data transmission 31. After the weak signal is amplified by the operational amplifier 30, the amplified signal will be transmitted to the electronic measuring device 32, and finally the electronic measuring device 32 will react to perform measurement.
