Adjustable device for matched installation of display module and mobile terminal base

Abstract

The invention discloses an adjustable device for matched installation of a display module and a mobile terminal base. The device comprises an LCM module fixing device, a front shell assembly fixing device, a negative pressure pneumatic adsorption device, a distance adjusting transmission device and a base platform device. The LCM module fixing device is rotatably connected with the base platform device. The negative pressure pneumatic adsorption device is mounted on the LCM module fixing device, for adsorbing the LCM module on the LCM module fixing device. The distance adjusting transmission device is mounted on the base platform device. When the LCM module fixing device drives the LCM module to press down, the front shell assembly fixing device is driven by the distance adjusting transmission device to move forward, so that a FPC just matches when the LCM module and the front shell assembly are installed, so as to prevent the FPC from being too short and broken by strong force pulling.

Description

technical field [0001] The invention relates to a smart phone, in particular to an adjustable device for matching and installing a display module and a mobile terminal base. Background technique [0002] As the application of smart phones becomes more and more popular, consumers are increasingly dissatisfied with simple functional requirements for smart phones, and tend to have high performance of smart phone functions, and have more and more requirements for the appearance of the visible area of ​​mobile phones. more stringent. [0003] The display and touch module (LCM module for short) assembled in the mobile phone is used as a separate material, which needs to be installed on the front shell of the mobile phone when the mobile phone is produced in the factory. The traditional method can only be installed manually, because the LCM module There are two features that make the fixture unusable: a. The LCM module is an electrical device.

[0003] The display and touch module (LCM module for short) assembled in the mobile phone is used as a separate material, which needs to be installed on the front shell of the mobile phone when the mobile phone is produced in the factory. The traditional method can only be installed manually, because the LCM module There are two features that make the fixture unusable: a. The LCM module is an electrical device. Because it must communicate with the motherboard, it must have a connector. The connector is snapped on the connector of the motherboard to achieve communication. For the purpose, the connector is extended from the LCM module body by the FPC, so that the fixture or equipment cannot be automatically positioned; b, the LCM module must be pasted to the front shell fixing area with double-sided tape, and this area is pre-installed with multi-section double-sided The surface adhesive and double-sided adhesive centrifugal paper need to be removed manually before installation, and this work cannot be carried out with effective fixture automation equipment; c, the FPC is relatively short, and the entire LCM module needs to be lowered after the connector is fastened Only when moving can be assembled, if the moving distance cannot be effectively controlled, the FPC will be pulled and broken

So there are currently the following problems: (1) It is easy to have deviations and cause uneven gaps; (2) It is easy to tear the FPC, resulting in defects; (3) The operation is difficult and takes a long time; (4) The consistency is poor, resulting in each piece being installed. The visual effect is different
