Jig for welding mobile phone display screen and backlight

Abstract

The invention discloses a jig for welding a mobile phone display screen and a backlight. The jig comprises a base, a supporting device fixedly arranged on the base to support the jig, a placing devicefixedly installed on the supporting device to place the mobile phone display screen and the backlight, a positioning device fixedly arranged on the placing device to position the mobile phone displayscreen and the backlight, a first fixing device mounted on the placing device to fix a flat cable of the backlight, and a second fixing device mounted on the placing device to fix the mobile phone display screen and the backlight; the supporting device can complete the adjustment of an angle ranging from 0 degree to 90 degrees, which is convenient for the placement, positioning and fixing of themobile phone display screen and the backlight and the positioning and fixing of the flat cable of the backlight, and the jig has the advantages of being convenient and fast in soldering, high in soldering accuracy, good in soldering effect and capable of adjusting the angle from 0 degree to 90 degrees.

Description

technical field [0001] The invention relates to the technical field of welding jigs, in particular to a jig used for welding a mobile phone display screen and a backlight source. Background technique [0002] The existing mobile phone display module generally includes a mobile phone display and a backlight. The mobile phone display is a liquid crystal display, and the end of the mobile phone display is provided with a cable. The backlight includes a backplane, a reflector, and a light guide plate from bottom to top. , Diaphragm, there is an LED light bar on the back panel, and the end of the LED light bar is provided with a backlight cable. During assembly, the mobile phone display cable and the backlight cable need to be plugged and then welded and fixed. Among them The cable refers to the flexible circuit board carrying electronic components.

Problems solved by technology

When the existing mobile phone display module is welded, the welding fixture generally used is a rectangular platform. When welding, the mobile phone display is placed on the rectangular platform with the back panel facing upward. At this time, the mobile phone display cable and backlight The source cable is closely attached to the back panel, and then use an electric soldering iron to solder the connection between the mobile phone display cable and the backlight cable, that is to say, the entire welding operation is carried out on the back panel, but the backlight The components of the backlight are relatively fragile, and the high temperature during welding can easily cause damage to the components in the backlight. For example, high temperature can cause local melting of the light guide plate, and the melting of the light guide plate will cause abnormal display of the backlight, which will lead to overall failure of the mobile phone display module. When using the existing welding jig for welding, there will be difficulties in the alignment of the mobile phone display cable and the backlight cable, welding difficulties and local high temperature generated by welding, resulting in low production and processing efficiency and production yield of mobile phone display modules.
