Abstract

The invention relates to a clamping device. The clamping device comprises a main jig and a first jig. The main jig is provided with a storage groove and a first positioning hole, the storage groove isused for storing a backlight module, the first jig is inserted into the first positioning hole, and the first jig is used for pressing the backlight module into the storage groove. When the clampingdevice is used, firstly the backlight module is placed into the storage groove of the main jig, then the first jig is inserted into the first positioning hole, and the first jig is made to tightly prop against the backlight module, so that the backlight module is prevented from being separated from the main jig. The backlight module can be stabilized through match between the main jig and the first jig, sliding of the backlight module in the detection process is avoided, and thus the accuracy of the detection result can be improved.

Description

technical field [0001] The invention relates to the field of optical component inspection, in particular to a clamping device. Background technique [0002] A liquid crystal display includes a display screen and a backlight module arranged in layers. The display screen itself does not emit light. The backlight module supplies the display screen with a light source with sufficient brightness and uniform distribution. The lighting effect of the backlight module directly affects the imaging quality of the display screen. Therefore, in order to ensure that the backlight module has a good luminous effect, it is necessary to strictly control the processing requirements of the backlight module, and accordingly, the detection of the backlight module is particularly important. [0003] The backlight module mainly has two specifications of right angle and arc angle. When using the traditional method to detect the backlight module, the backlight module is usually fixed with tape, and t...
