Circuit board automatic smoothing machine and smoothing method

Abstract

The invention discloses an automatic smoother for a circuit board. The automatic smoother for the circuit board includes a frame platform, a feeding mechanism, a hot-pressing smoothing mechanism and a discharge mechanism are arranged on the frame platform in sequence, and the hot-pressing smoothing mechanism includes a beam frame and at least one smoothing device. The automatic smoother for the circuit board in the invention can rapidly perform automatic smoothing operation on an OLB position of a flexible circuit board, has a good smoothing effect, enables the OLB position of the flexible circuit board not to be easy to restore, facilitates subsequent fitting operation of the flexible circuit board, can reduce a reject rate in a fitting process and production cost, and has the advantages of high work efficiency, simple structure, convenient operation and the like. In addition, the invention also discloses a smoothing method of the automatic smoother for the circuit board.

Description

technical field [0001] The invention relates to the technical field of flexible circuit board processing equipment, and more specifically relates to an automatic circuit board smoothing machine and a smoothing method thereof. Background technique [0002] Flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film, referred to as soft board or FPC, with high wiring density and light weight. , thin thickness, mainly used in many electronic products such as mobile phones, tablet computers, notebook computers and digital cameras. [0003] OLB (outer lead bonding) refers to TAB (Tape Automatic Bonding, tape automatic combination) outer four-sided external pins, which can be soldered to the corresponding pads on the circuit board, called "outer lead bonding" ". [0004] In the process of attaching and connecting flexible circuit boards, it is generally necessary to attach the OLB of the circuit board to the termin...

AI Technical Summary

Problems solved by technology

[0004] In the process of attaching and connecting flexible circuit boards, it is generally necessary to attach the OLB of the circuit board to the terminals of the panel (LCD screen) with ACF (anisotropic conductive film) through an ACF attaching machine, such as Figure 11 As shown, in the process of OLB identification and bonding, because the OLB part of the newly produced circuit board is easy to bend upwards (that is, warped), the identification of the OLB is poor. high, increasing production costs

Therefore, manufacturers generally smooth the OLB part of the circuit board first, but the existing smoothing operation is usually manual or semi-automatic flattening operation, because the flexible circuit board has recovery characteristics, so it will be restored after a period of time To the tilted state, the smoothing effect is not ideal. In addition, the above two operation methods have the disadvantage of low work efficiency
