Abstract
The invention relates to a light leak detection device. The light leak detection device comprises a clamp unit and a detection device body. The clamp unit comprises a base. A fixing block is arranged at one end of the base, and a fixing sliding block is arranged at the other end of the base. An electronic product to be detected is installed between the fixing block and the fixing sliding block. Light blocking foam is arranged on the portion, between the fixing sliding block and the fixing block, of the base. A groove is formed in the portion, between the light blocking foam and the fixing block, of the base, and the detection device body is arranged in the groove. The arranged light blocking foam has the effect of preventing the surface of a display screen from making contact with the base in the detection process to protect the surface of the display screen and also has the effect of forming a closed space together with the fixing block to guarantee a sufficient detection light source; a plurality of sensors are arranged, an MCU control unit sends data to an external PC for calculation, and therefore the detection process is quantified.
Description
Technical field
The present invention relates to a kind of checkout equipment, be specifically related to a kind of light leakage detecting device for detection display screen.
Background technology
Along with the technical development of consumption electronic product, display screen has become the most key part of many consumption electronic products, and is the product quality ensureing to dispatch from the factory, and must detect the quality of display screen.Display screen is installed not in place, and causing screen liquid crystal to follow frame edge to coincide and closely do not cause fluorescent tube Transmission light out light leak, is a more common class problem.Current display light leakage detecting device structure is too complicated, and detection means lacks the method quantized, and can not test out display screen whether light leak rapidly by simple device.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of light leakage detecting device of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of can detection display screen love light leak pick-up unit, to meet the needs in display screen production run.
The technical scheme of a kind of light leakage detecting device of the present invention is as follows:
A kind of light leakage detecting device, comprise and add fixture unit and pick-up unit, described fixture unit comprises a pedestal, described pedestal one end is provided with a fixed block, the described pedestal other end is provided with a fixing slide block, between described fixed block and described fixing slide block, electronic product to be detected is installed, it is characterized in that: described pedestal is provided with between described fixing slide block and described fixed block one and is in the light foam, described pedestal is provided with a groove described being in the light between foam and described fixed block, and described pick-up unit is arranged in described groove.
Further, described pick-up unit comprises optical sensor module, communication interface module and operational analysis module, described communication interface module has a receiving end and output terminal, the photosignal that described receiving end sends for receiving described optical sensor module, described output terminal is used for described photoelectric signal transformation to become digital signal to send to described operational analysis module.
Further, being provided with MCU in described communication interface module is control module.
Further, described operational analysis module is PC.
By such scheme, the present invention at least has the following advantages:
(1) the be in the light foam of the present invention by arranging, can play two effects, one is protect display screen surface, to make in testing process not with base into contact, two is the effects serving an enclosure space with fixed block, makes detection light source abundant.
(2) the multiple sensors of the present invention by arranging, are calculated at the PC being sent the data to outside by MCU control unit, testing process are quantized.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
