Abstract

The invention discloses a spring, base material and edge material connection structure which is conveniently split. The structure comprises springs, base materials and edge materials, wherein two ends of each base material are in semi-etching connection with the edge materials, one side of each spring is in semi-etching connection with each base material, each base material is in semi-etching connection with one side of each spring through two connecting positions, each edge material is in semi-etching connection with the multiple base materials, each base material is in semi-etching connection with the multiple springs, one row of springs and the edge materials of corresponding positions are compacted by use of a fixture, only etching portions are reserved, the base materials are separated from the edge materials by use of tweezers, then, the base materials are drawn along the normal direction of the springs to enable the base materials and the springs to be cut separate along a semi-etching line, afterwards, base material portions are removed, and the springs are obtained. The spring, base material and edge material connection structure is simple and ingenious in structure, only one side of each spring is in semi-etching connection with the base materials, compared to a conventional mode of connecting two edges or four edges of each spring with the base materials, after splitting, the springs can be directly put into production and service, distinguishing of direction surfaces is prevented, and production and application of defective products are reduced.

Description

Shell fragment, mother metal and rim charge syndeton and shell fragment method for splitting

Technical field

The present invention relates to field of motors, shell fragment, mother metal and rim charge syndeton that especially a kind of convenience splits and shell fragment method for splitting.

Background technology

The fractionation major part of existing voice coil motor is separated with mother metal by single product shell fragment with trembling shell fragment machine, then carries out balance by certain face, direction, come into operation after product being set dish.Present shell fragment and mother metal mainly carry out half-etching with four limits or both sides and are connected, this connected mode is shell fragment and mother metal separation difficulty when splitting, in split process, very easily cause distortion again simultaneously, shell fragment positive and negative after fractionation is classified, balance after needing face, direction to distinguish when so just causing balance, adds working strength and defective products.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of convenient shell fragment, mother metal and rim charge syndeton split, avoid shell fragment to overlap when splitting, be out of shape and balance time differentiation to face, shell fragment direction, directly can use aborning, save balance operation.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is:

Shell fragment, mother metal and rim charge syndeton, comprise shell fragment, mother metal and rim charge, and mother metal two ends are connected with rim charge half-etching, and shell fragment side is connected with mother metal half-etching.

Further, mother metal is connected with the side half-etching of shell fragment by connection bit.

Preferably, the width of connection bit is 0.30mm to 0.6mm.

Further, the connection bit quantity that mother metal is connected with each shell fragment half-etching is determined according to shell fragment size.

Preferably, mother metal and shell fragment half-etching part total length are 7% to 13% of shell fragment local width.

Preferably, the length of mother metal and rim charge half-etching part is 12% to 19% of shell fragment length.

Preferably, each rim charge is connected with multiple mother metal half-etching, and mother metal is uniformly distributed, and each mother metal is connected with multiple shell fragment half-etching, and shell fragment is uniformly distributed.

Shell fragment method for splitting, the steps include:

One row's shell fragment and corresponding position rim charge are compressed with tool when splitting, only reserve etching part, with tweezers, mother metal is separated with rim charge, then mother metal is drawn along shell fragment normal direction, mother metal is separated along half-etching Linear cut with shell fragment, rear removal mother metal part, obtain shell fragment, shell fragment directly puts into production use.

The invention has the beneficial effects as follows:

Shell fragment of the present invention only has side to be connected with mother metal half-etching, and compare existing shell fragment both sides or four limits are connected with mother metal, and after fractionation, shell fragment can directly put into production use, and avoids and distinguishes face, direction, reduces defective products and produces and balance.
