An FPC bending hot air gun preheating device

Abstract

The invention discloses a preheating device for an FPC bending hot air gun, and relates to the technical field of FPC bending. The FPC bending hot air gun preheating device includes a motor, a turntable is fixedly installed on the output shaft of the motor, and a hot air blower is arranged above the turntable, and the air outlet of the hot air blower is fixedly connected with the top of the shunt pipe, and the shunt pipe The bottom end of the turntable is fixedly connected to the middle of the top of the turntable. The upper surface of the turntable is fixedly installed with several closed heating mechanisms distributed in an equidistant and surrounding shape, and each closed heating mechanism is provided with a hot air conveying mechanism and a micro cylinder. The FPC bending hot air gun preheating device, through the setting of the closed heating mechanism, enables the FPC to be heated in a closed environment. Compared with the traditional heating method, it can effectively reduce the heat loss. The batch heating mode can control the heating effect of a single FPC more precisely.

Description

technical field [0001] The invention relates to the technical field of FPC bending, in particular to an FPC bending hot air gun preheating device. Background technique [0002] The flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. Referred to as FPC or FPC, it has the characteristics of high wiring density, light weight and thin thickness. At present, with the upgrading and thinning of the functions of mobile electronic devices, in order to adapt to the internal structure of electronic devices, the requirements for the bending shape of FPC are getting higher and higher. Because of its good forming effect and small rebound, LCP sheets have been widely used in the past two years. However, cold bending of LCP board is prone to fracture or delamination, so the board needs to be preheated before bending. [0003] The traditional heating method heats the FPC surface by blowing hot air diversion. Such a h...

However, cold bending of LCP boards is prone to breakage or delamination, so the board needs to be preheated before bending

[0003] The traditional heating method heats the FPC surface by blowing the hot air. This heating method easily leads to uneven heating of the FPC surface, and there is a heating blind area, which affects the subsequent bending process.
