A kind of FPC assembly jig and assembly method thereof

Abstract

The invention discloses an FPC assembly jig, which comprises a base and a block, the base is provided with positioning pins, and the block is vertically arranged on the top surface of the base. The FPC gold finger rests on the stopper and can pass through the through hole of the bracket accurately. The functions of aligning the PFC with the bracket and inserting the gold finger into the through hole of the bracket are realized in the same process of the same jig, avoiding the gap between the holes. The misalignment caused the customer to not be able to drive in the screw, which solved the problem of difficulty in sticking the golden finger.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an FPC assembly fixture and an assembly method thereof. Background technique [0002] FPC is the abbreviation of Flexible Printed Circuit, also known as flexible circuit board, flexible printed circuit board, flexible circuit board, widely used in many electronic products such as mobile phones, notebook computers, PDAs, digital cameras, LCM, etc., realizing lightweight, Miniaturization and thinning, so as to achieve the integration of component devices and wire connections. Some of the FPCs need to be pasted on the bracket. For practitioners, how to achieve fast and accurate pasting is a direction worth studying. [0003] Such as Figure 1a As shown, the patent document No. 200720122023.5 discloses a positioning device for pasting FPC boards, including a base 3, a product positioning seat 4, and a product backing plate 5; The product backing plate 5 and the product positioning pin 9 of the ...

AI Technical Summary

Problems solved by technology

[0004] In the actual production process, such as Figure 1b to Figure 1d As shown, the FPC may include a gold finger 1 structure that needs to be bent. The flat part 2 of the finished FPC is on the front of the bracket, and the gold finger 1 is on the back of the bracket. There are mainly two installation methods. The first method adopts the simple Fixture, there are positioning pins 3 on the fixture. This fixture can only ensure the alignment of the FPC flat part 2 and the bracket. Afterwards, it is still necessary to manually insert the FPC gold finger 1 into the bracket hole 4. This process is very difficult to operate, because the FPC gold finger 1 The area is small, the bracket hole 4 is small, but the human finger is much larger than the bracket hole 4, it is very difficult to insert the golden finger 1 alone into the bracket hole 4, and even the FPC will be torn or the bending part will be seriously wrinkled

The second way is to manually remove the FPC release paper, first insert the gold finger 1 into the bracket hole 4, and then paste the FPC plane part 2, but the alignment between the FPC and the bracket cannot be guaranteed, and there are great hidden dangers in the quality, and the stability cannot be guaranteed.
