Problems solved by technology
Under the premise of not affecting the electrical performance of the piezoelectric buzzer, the present invention adopts a thin plate through a multi-stamping die to integrally form the guide pin shrapnel and the cylindrical guide pin lead-out pin, thereby solving the problem of insufficient rigidity of the flat pins of the current piezoelectric buzzer. When the automatic plug-in machine is plugged in, there are shortcomings of unstable pin cutting, poor welding reliability of the electric welding guide pin, and poor electrical performance consistency of the piezoelectric buzzer due to excessive elasticity of the pure circular guide pin.

The invention discloses an AI plug-in buzzer and a method of manufacturing a guide pin spring. The buzzer includes a bottom casing, a surface casing is arranged on the bottom casing, the space formed by the bottom casing and the surface casing is provided with a buzzer plate, two thin plate guide pin springs are arranged under the buzzer plate, each guide pin spring includes an elastic arm, guide pin buckle positions, a guide pin contact, and a pin, the guide pin contact is arranged at the top end of the elastic arm, the guide pin buckle positions are symmetrically arranged at the two sides of the elastic arm, the pin is arranged at the lower end of the elastic arm and is formed by curling a whole piece of thin plate, the bending end is provided with a slit, and the guide pin springs extend out of the bottom casing via the pins. Each plate guide pin spring is formed by one-step stamping of multi-step continuous stamping molds and is integrally formed. The AI plug-in buzzer solves the problems that the flat pin of the conventional piezoelectric buzzer is insufficient in rigidity, so that the pin shearing is unstable when an automatic plug-in device plugs in, the electric welding of an electric welding guide pin is bad in firmness, and the piezoelectric buzzer is bad in electrical property consistency because pure circular guide pins are large in elastic force.
Description
technical field [0001] The invention relates to an AI plug-in buzzer and a method for manufacturing guide pin shrapnel, belonging to the technical field of buzzer manufacturing. Background technique [0002] At present, most of the pins of thin-plate taped buzzers on the market use two types. One is the metal conductor guide pin design with a thickness of 0.20mm, and the pins are formed everywhere. This design is thin and insufficient in rigidity. There are defects such as that the pins are not easy to cut when the automatic plug-in machine is plugged in. One kind of lead-out pin is connected by spot welding, which solves the strength of the lead-out pins, but the electric welding connection process is complicated, and it is easy to cause unreliable electric welding, which leads to defective products. The above-mentioned defects are needs improvement. Contents of the invention [0003] In order to solve the above-mentioned technical defects, the present invention provides...
