Automatic wire bending and cutting device

Abstract

The invention relates to an automatic wire bending and cutting device of a wire of a buzzer. The device comprises a support. A wire bending mechanism used for bending the wire is arranged on the support, and a cutting mechanism used for cutting the wire bended by the wire bending mechanism is arranged on one side of the wire bending mechanism. The wire bending mechanism comprises a driving wire bending gear arranged on the support, a driven wire bending gear matched with the driving wire bending gear to conduct wire bending, a measurement disc arranged on the driven wire bending gear and rotating with the driven wire bending gear and a detection sensor located on one side of the measurement disc to detect rotating distance of the measurement disc in real time. The cutting mechanism comprises a cutting knife, a driver arranged on the support and used for driving the cutting knife to cut the bended wire and a controller used for receiving measurement disc rotating distance signals detected by the detection sensor. The controller controls the driver to work according to the received measurement disc rotating distance. The automatic wire bending and cutting device is capable of bending a straight wire into a bended wire automatically and automatically cutting the wire according to required length, thereby being high in working efficiency.

Description

Technical field [0001] The invention relates to the technical field of wire cutting equipment, in particular to a buzzer automatic wire bending and cutting device. Background technique [0002] Piezoelectric patch type buzzers use straight wires to conduct electricity, and when the straight wires are glued and fixed, because the glue position of the glue machine is fixed, if the position of the straight wires cannot be placed in the designated position, It will increase the difficulty of glueing, and the glue will not stick to the wire, and because the straight wire has no tension, it is easy to cause the wire to be broken in the production and use process; now the bent wire is used to replace the straight wire to eliminate the above The problem is that the bending line needs to be carried out with equipment. Summary of the invention [0003] In view of the above technical problems, the present invention provides an automatic wire bending and cutting device, which can automatical...

Problems solved by technology

[0002] Piezoelectric chip buzzers use straight wires to conduct electricity, and when the straight wires are glued and fixed, due to the fixed position of the glue machine, if the position of the straight wires cannot be placed at the specified position, It will increase the difficulty of gluing, and there will be situations where the glue cannot bond the wires, and because the straight wires have no tension, it is easy to cause wire breakage during production and use; now bent wires are used to replace straight wires to eliminate the above-mentioned The problem, and the bending line needs to use equipment to carry out
