FPC surface rubberizing device

Abstract

The invention discloses an FPC surface rubberizing device. The device comprises a mounting plate for positioning and mounting a whole FPC board, and a turnover plate which is connected to the mountingplate in a turnover manner and is used for positioning and mounting a PSA board; the surface of the mounting plate and the surface of the turnover plate are each provided with a plurality of suctionholes used for generating negative pressure suction effects on the FPC board and the PSA board, and the turnover plate enables the PSA board to be attached to the FPC board when being turned over to be attached to the surface of the mounting plate. Thus, under the action of the suction holes, when the FPC board is mounted on a surface of the mounting plate, the FPC board can be kept completely stretched under the action of negative pressure suction, and the phenomenon of curling and bending is avoided; and meanwhile, when the PSA board is mounted on the surface of the turnover plate, all partsof the surface of the PSA board can be kept flat under the action of negative pressure attraction, and the phenomenon of bending and wrinkling is prevented. Therefore, the FPC surface rubberizing efficiency can be improved, meanwhile, the PSA is prevented from bending and wrinkling in the attaching process, and it is guaranteed that the rubberizing position is accurate.

Description

technical field [0001] The invention relates to the technical field of SMT, in particular to an FPC surface gluing device. Background technique [0002] With the development of electronic technology, more and more electronic devices have been widely used. [0003] Cable is also called flexible printed circuit board (FPC, Flexible Printed Circuit), which stipulates the wiring rules, line sequence, line color, line number, etc. The data cables connecting the internal motherboard to the hard disk and optical drive, the data cables connecting the mobile phone motherboard to the display, and the data cables connecting devices are collectively referred to as flat cables. [0004] At present, the method of pasting PSA (pressure sensitive adhesive, pressure sensitive adhesive) on small FPCs is generally to divide the whole board of FPC into independent single FPCs with a sub-board machine, and then paste the PSA, because the PSA and Flex paste Together there are precision requirem...

Problems solved by technology

[0005] However, the PSA structure in the prior art can only process a small number (such as 4) of individual FPCs at the same time. If the number continues to increase, the material will easily bend and wrinkle due to the increase in the area of ​​the PSA. Pasting occurs, causing the entire PSA to be scrapped

Moreover, in the prior art, the entire FPC board must first be divided into boards, and then each individual FPC board must be subjected to PSA attachment processing, the process flow is relatively cumbersome, and the attachment efficiency is low.
