Description

Puncture punching and bending tool for producing flexible circuit board

Technical Field

The utility model relates to a flexible circuit board technical field specifically is a puncture towards curved frock of production flexible circuit board.

Background

A Flexible Printed Circuit Board (FPC) is a Printed Circuit Board having high reliability and excellent flexibility, which is made by etching a Circuit on a copper foil using a mylar or polyimide as a base material. The flexible printed circuit board has many advantages that the rigid printed circuit board does not have, for example, it can freely bend, roll and fold, can be randomly arranged according to the space layout requirement, and can freely move and stretch in a three-dimensional space, thereby achieving the integration of component assembly and wire connection.

Along with the society constantly develops, more and more people use cell-phone terminal as communication tool, and the function realization of cell-phone button needs flexible circuit board and shell fragment laminating, however traditional laminating mode in the present trade is manual laminating, because the size of flexible circuit board itself is less, produces the off normal easily in manual laminating in-process, and machining efficiency is low, therefore the flexible circuit board through the mode production of manual laminating can't satisfy the market demand.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a puncture towards curved frock of production flexible circuit board has solved the problem that current flexible circuit board and shell fragment still need manual laminating.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a puncture punching and bending frock of production flexible circuit board, includes fixed panel and is fixed in the locating plate of fixed panel one side, be equipped with the push rod on the locating plate, push rod and fly leaf fixed connection, still be equipped with the spring between fly leaf and the locating plate, the fly leaf opposite side is fixed with the drift, the drift bottom is equipped with the bottom plate, set up the indent with drift shape matched with on the bottom plate.

Preferably, a pressing block is further arranged between the bottom plate and the movable plate.

Preferably, the punch and the pressing groove are provided in plurality.

Preferably, the movable plate is provided with a clearance groove, and the punch can move in the clearance groove and limit.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model punches the flexible circuit board by the punch of the movable plate driven by the push rod, and can bend and stick the redundant metal of the elastic sheet to the flat FPC when the flexible circuit board is punctured, the whole process is automatic, manual sticking is not needed, time and labor are saved, and safety and high efficiency are realized; and a spring is arranged between the movable plate and the positioning plate, and the movable plate can automatically reset through the spring after being stamped once.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. fixing the panel; 2. positioning a plate; 3. a push rod; 4. a movable plate; 5. a spring; 6. a punch; 7. a base plate; 8. pressing a groove; 9. briquetting; 10. and (5) avoiding a clearance groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in the accompanying drawing 1, the utility model provides a production flexible circuit board puncture towards curved frock, include mounting panel 1 and be fixed in the locating plate 2 of mounting panel 1 one side, be equipped with push rod 3 on the locating plate 2, push rod 3 and fly leaf 4 fixed connection, still be equipped with spring 5 between fly leaf 4 and the locating plate 2, fly leaf 4 opposite side is fixed with

drift

6, 6 bottoms of drift are equipped with bottom plate 7, set up on the bottom plate 7 with 6 shape matched with indent 8 of drift.

A pressing block 9 is further arranged between the bottom plate 7 and the movable plate 4, a plurality of punches 6 and pressing grooves 8 are arranged, clearance grooves 10 are formed in the movable plate 4, and the punches 6 can move in the clearance grooves 10 and are limited.

The utility model discloses at the during operation, push rod 3 and cylinder are connected, and the cylinder drives push rod 3 and moves down to it moves down to drive fly leaf 4, flexible circuit board and shell fragment are fixed at briquetting 9 downside, and its position that needs the laminating sets up with indent 8 on the bottom plate 7 is corresponding, then fly leaf 4 drives drift 6 and moves down to the direction removal that is close to the flexible circuit board, and drift 6 can be with the surplus metal of shell fragment bending subsides flat flexible circuit board when pricking flexible circuit board, and drift 6 can move in keeping away dead slot 10 when pushing down simultaneously, frictional force when buffering the punching press, fly leaf 4 is after accomplishing a punching press step, because spring 5's setting can automatic re-setting, in order to make things convenient for next punching press process.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
