A clamp for a plate-shaped device

Abstract

The invention relates to a plate-shaped device clamp, more specifically, the invention relates to a clamp for structure tests oriented to devices, such as notebook computer and flat computer products.The clamp is composed of a flexible clamping module, a mounting rack module and a main base plate module; the flexible clamping module is mainly used for clamping and fixing a plate-shaped device; the mounting rack module is fixedly mounted on the main base plate module, has capability of being quickly separated from the main base plate module and is mainly used for fixedly connecting the flexible clamping module; the main base plate module is used for realizing a clamping and fixing effect on the mounting rack module, and has capability of being connected with a conventional workbench and astandard mechanical frame. The plate-shaped device clamp has the characteristics of having good universality, flexibility, simplicity and convenience in operation and clamping stability, being capableof greatly improving efficiency of automatic test, and so on, moreover, main parts of the clamp are all modularized design, which is convenient for manufacturing and maintenance and also provides possibility for upgrading and rebuilding of the parts, thus, the clamp can be widely used for clamping and fixing the plate-shaped devices.

Description

technical field [0001] The invention relates to a clamp suitable for clamping a plate-shaped device. More specifically, the present invention relates to a fixture required for structural testing of devices such as notebook computers and tablet computer products. Background technique [0002] For automated testing of important components such as shafts and touch screens in laptops, tablet computers, etc., it is first necessary to effectively fix the device to be tested, and usually select a regular board-shaped structure in the device for fixing operations, such as the keyboard board of a laptop. to fix. [0003] A conventional fixing method is to provide a tray structure for placing and fixing the plate-shaped structural components in the device to be tested. For example, in the scheme of patent ZL201010103922.7, a workbench on which the capacitive touch screen to be tested can be placed on the top surface can be used to place a flat touch screen or a tablet computer; in t...

For example, in the scheme of patent ZL201010103922.7, a workbench on which the capacitive touch screen to be tested can be placed on the top surface can be used to place a flat touch screen or a tablet computer; in the scheme of patent ZL201210295129. To measure the ultra-thin carrier structure of the workpiece, place the laptop computer to be tested on it and fix it with clamping blocks in actual use. The disadvantage of this clamping method is that the vibration and structural thickness of the ultra-thin carrier will affect the test accuracy. It has a great influence on the movement range of the notebook computer's shaft angle; in the patent ZL201410224644.9 scheme, a modular and flexible fixture for clamping and fixing computer products is provided, which is composed of several fixture units, each fixture The units can clamp the side structure of the notebook computer, and the units can be horizontally installed on the reference table at any relative position to adapt to the clamping of computer products of different sizes, thereby realizing the mechanical performance of the notebook computer shaft. For automated testing, the solution of flexible fixtures in this method effectively overcomes the shortcomings of the aforementioned method of clamping and fixing the ultra-thin stage, but the operation of fixing and installing the notebook computer to be tested at a time is relatively cumbersome, and each fixture unit needs to be carried out correspondingly one by one. Slack operation, which affects its application in more automated testing situations
