Automatic feeding device and control method for buzzer dispensing

Abstract

The invention discloses an automatic feeding device and control method for buzzer dispensing. The device comprises a vibration conveying device and a dispensing positioning device. The vibration conveying device comprises a vibration plate, a first feeding guide rail, a second feeding guide rail and a direct vibration device. A first positioning convex strip and a second reflective photoelectric sensor are arranged on the side, in the direction opposite to the conveying direction of the second feeding guide rail, on a dispensing platform. A push mechanism is arranged at the end, in the direction perpendicular to the conveying direction of the second feeding guide rail, on the dispensing platform, and a second positioning convex strip and a first reflective photoelectric sensor are arrangedat the other end of the dispensing platform. By the adoption of the automatic feeding device for buzzer dispensing, whether the number of workpieces in the second feeding guide rail reaches the fullcapacity or not is judged according to a signal of an opposite-type optical fiber sensor, and the vibration disc is controlled to stop vibrating. When the number of workpieces in the second feeding guide rail reaches the set lower limit value, the vibrating plate is started, so that the continuity of the feeding is ensured, the vibration time of the vibrating plate is shortened, the energy is saved, the starting and stopping frequency of the vibrating plate is reduced, and the service life of the vibrating plate is prolonged.

Description

technical field [0001] The invention relates to an automatic feeding device and a control method, in particular to an automatic feeding device and a control method suitable for buzzer dispensing. Background technique [0002] The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, and timers. . Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. [0003] The sounding principle of the buzzer is composed of a vibration device and a resonance device, and the buzzer is divided into a passive self-excited type and an active self-excited type. The working and sounding principle of the passive separately excited buzzer is: the square wave signal is input into the resonance device and converted into the sound signal output; the workin...

AI Technical Summary

Problems solved by technology

[0005] Before the dispensing operation, the buzzer needs to be transported to the dispensing position by an external mechanism. However, the structure of the existing automatic feeding device is unreasonable, and the connection with the positioning device is not accurate enough, which affects the subsequent dispensing work. At the same time, The buzzer cannot be effectively positioned during the dispensing process, which further affects the dispensing effect
