Hard disk magnetic head front control soft line board v-l-u bending three-in-one device

Abstract

The invention relates to a V-L-U bending three-in-one device of hard disc magnetic head predictor control soft line board. The V-L-U bending three-in-one device comprises a turn platform, a V-shaped bending mechanism, an L-shaped bending mechanism and a U-shaped bending mechanism. A locating block is arranged on the turn plate, and the V-shaped bending mechanism, the L-shaped bending mechanism, the U-shaped bending mechanism and a blanking mechanism are sequentially arranged on the circumference of the side portion of the turn plate. The V-L-U bending three-in-one device achieves three-in-one bending, V-shaped bending, L-shaped bending and U-shaped bending are combined and completed in one step, and bending of three shapes is completed with once location. The influence brought by repeated location of a product and locating basis changes is solved, and the accuracy and the stability of V-shaped forming, L-shaped forming and U-shaped forming of the products are guaranteed with once location.

Description

technical field [0001] The invention relates to a device for bending and forming a hard disk magnetic head front control flexible wire board, in particular to a hard disk magnetic head front control flexible wire board V-L-U bending three-in-one device. Background technique [0002] The forming technology of the hard disk head front control soft line board is very critical. There are three bending shapes: V-shape, L-shape and U-shape. The flexible wire board consists of three parts: the flexible wire circuit board with a thickness of 0.06mm, the front-end board and the base board. At this time, the protection of the soft line board is particularly important. [0003] In the existing production process, the bending of flexible wire board is also divided into V, L and U-shaped bending, but it is divided into two processes to complete. The L-shaped bending and V-shaped bending are formed by a set of tooling and transferred to the In the next process, another set of tooling is...

AI Technical Summary

Problems solved by technology

The quality after bending cannot be guaranteed from the analysis of the production process, so the CPK of the products produced now is less than 1.0, and the UPH is 230 pieces per hour. A large number of technicians to maintain production

Because it is a different process to complete the highly correlated bending, not only the relevant dimensions cannot be guaranteed due to human factors, but also the positioning of two different positions produces a large positioning error, and the quality is difficult to guarantee
