Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 1 to 4, the present invention provides an assembly jig for an LCM, including: the tool body, the tool body includes: 1 support, locating piece 2 and a plurality of elastic component, 1 support and locating piece 2 pass through elastic component realizes elastic connection, and locating piece 2 can be relative support 2 downstream and upwards reset, locating piece 2 corresponds backlight unit and forms first location structure, first location structure is used for fixing a position backlight unit, it forms second location structure to correspond the LCD module on the first location structure, second location structure is used for fixing a position the LCD module, support 1 is in 1 below department of locating piece is formed with a boss 11, first location structure and second location structure correspond boss 11 is equipped with and keeps away the dead zone.

Specifically, with continuing reference to fig. 1 to 4, in the present embodiment, the first positioning structure includes: the first groove 21 is used for accommodating a backlight module, the third groove 23 is used for accommodating a backlight FPC (flexible printed circuit) in the backlight module, the second positioning structure comprises a second groove 22 arranged in the first groove 21, and the second groove 2 is used for accommodating an LCD module. In this embodiment, the elastic component is a spring 3. The jig body further comprises a plurality of screws 4, a first screw hole is formed in the support 2, a second screw hole is correspondingly formed in the positioning block 1, and the screws 4 are arranged at the first screw hole and the second screw hole. The jig body is formed with accommodation space in screw department, spring 3 locates in the accommodation space, just screw 4 runs through the cavity setting in spring 3 center. The screw 4 can be used for limiting and stabilizing the positioning block 2. The support 1 and the positioning block 2 can be made of Teflon. The jig body is provided with 2 notches 12 which are convenient for taking and placing the backlight module or the LCD module and are respectively arranged at the left side and the right side of the jig body.

Referring to fig. 1 to 4, when the present invention works, the LCD module is first placed in the second groove 22, the backlight module is then placed in the first groove 21, the positioning block 2 or the backlight module is then pressed to move the positioning block 2 downward, the backlight module moves downward along with the positioning block 2, and due to the presence of the boss 11 and the clearance area, the LCD module stops moving downward due to the blockage of the boss 11 when moving downward along with the positioning block to the position of the boss, and the backlight module continues to move downward until stopping moving downward due to the blockage of the LCD module, and at this time, the backlight module contacts with the LCD module to achieve alignment and attachment. When the downward force is released, the positioning block 2 is upwards bounced to reset due to the action of the spring 3, the backlight module and the LCD module are driven to move upwards, and then the attached products can be taken out through the gaps 12 on the two sides of the jig body.

In summary, the backlight module and the LCD module are aligned simultaneously by the positioning block in a reverse assembly mode, so that the requirement of high alignment precision can be met, and high-precision alignment is realized; the jig is simple and convenient to assemble, production efficiency is improved, damage to the modules is avoided, and yield and production efficiency can be improved.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
