Description
Technical Field
The utility model relates to a test machine technical field refers in particular to an automatic counterpoint LCD screen lights and judges test machine.
Background
In a liquid crystal module factory in the market at present, when a finished liquid crystal module after being processed is lightened to perform a functional performance test, a used functional test instrument product is a common pure manual tester, and alignment of a liquid crystal module FPC (flexible printed circuit) golden finger and a circuit switching board golden finger of the tester needs manual alignment, naked eyes need to look at the product, so that point-like defects are too small, alignment process efficiency is low, and the alignment process is not easy to find and pick out.
The foregoing test operations were as follows:
the method comprises the following steps that firstly, products are taken from a production line or a material tray and placed on a lighting tester;
secondly, after the product is placed, an operator needs to align the product by naked eyes (the FPC golden fingers and the tester switching plate golden fingers are aligned one by one, and the tester cannot be electrified to input signals to light the liquid crystal module due to alignment errors);
thirdly, after alignment, manually pressing down a pressure lever to press an FPC golden finger fixing block on the pressure lever, so that the FPC golden finger and a tester adapter plate golden finger are tightly combined to be in signal connection with each other;
fourthly, after the golden finger of the FPC of the liquid crystal module is aligned and tightly attached to the golden finger of the adapter plate of the tester, a switch of the tester is opened to electrify the tester and the liquid crystal module, and then the liquid crystal module is lightened;
and fifthly, after the liquid crystal module is lightened, the inspection picture is switched back and forth, and whether the defect exists or not is confirmed by staring a small liquid crystal module through an elbow of an operator.
As can be seen from the above description, the conventional LCD module test has the following disadvantages:
1. the golden finger of the FPC of the liquid crystal module and the golden finger of the adapter plate of the tester are too small, manual alignment is needed, and the efficiency is low;
2. the inspection needs the confirmation of lowering the head of an operator, and the operator is difficult to work for a long time and easy to hump back;
3. one defect (black and white point) is too small to be found easily and is easy to miss detection;
4. when people stare at the small-size screen for a long time to watch, the eyes are injured, and the killing power to the eyes is great;
5. the detected defective products are mixed in the good products due to operator negligence, and the good products flow to customers to cause customer complaints.
