Backlight module and FPC welding alignment device

Abstract

The invention discloses a backlight module and FPC welding alignment device. The device comprises a mounting bottom plate, an adsorption mechanism, an X-direction alignment driving mechanism, a Y-direction alignment mechanism, a Z-direction movement mechanism and a switching connection piece; the X-direction alignment driving mechanism comprises a first movement module sliding in an X direction and a first driving device connected with the first movement module; the Y-direction alignment mechanism comprises a second movement module, a third movement module, a second driving device, and an upper alignment part, wherein the second movement module and the third movement module slide in a Y direction, the second driving device is connected with the second movement module, and the upper alignment part is connected with the second driving device; a third driving device can drive the upper alignment part to move in a Z direction; a second connecting piece is fixedly connected with the third movement module; the upper alignment part is an upper clamping jaw or a friction rod; the Z-direction movement mechanism is fixedly connected with the second movement module and comprises a lower clamping jaw and a fourth driving device; and the switching connection piece is selectively and fixedly connected with the first movement module and the second movement module or the second movement moduleand the third movement module. The device has a friction alignment mode and a clamping alignment mode, and can be quickly switched between the two alignment modes.

Description

technical field [0001] The invention relates to the technical field of flexible circuit board welding, in particular to a backlight module FPC welding alignment device. Background technique [0002] In the welding production process of the LCD display product FPC, the product FPC is diverse, and the welding position of the backlight FPC and the main FPC needs to be aligned to meet the alignment requirements during welding, and then welded. [0003] At present, the common alignment method is clamping alignment. Usually, the clamping part is used to clamp the pins of the backlight FPC from the gap between the main FPC and the backlight FPC, so that the gold fingers set at one end of the pins move to the main FPC. At the pad, the alignment is realized by confirming OK through the image. This clamping alignment method requires that the gap between the main FPC and the backlight FPC must be moderate, allowing the clamping part to pass through. If the gap is too small, it will be...
