Description of drawings
Fig. 1 is system chart of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the utility model comprises computer control, shooting disposal system, mechanism controls unit, illuminator and transmission system.The shooting disposal system all is connected with computer control with the mechanism controls unit, and illuminator then all is connected with the mechanism controls unit with transmission system.Computer control is the core of whole device, and whole testing process of the present utility model is controlled to finish to other system and parts by computer control; Transmission system is used for monitoring and the location to battery; Illuminator is used to whole device that light source is provided, and white light can be decomposed into the obvious GTG light of colorama or comparison of light and shade, so that the different piece on the battery can be distinguished by system; The shooting disposal system is used for the image of picked-up battery and it is processed; The mechanism controls unit then is to control respectively transmission system and illuminator operation according to the instruction of computer control transmission, and also be respectively arranged with interface unit, control panel, status indicator lamp on this mechanism controls unit, interface unit is used for carrying out communication to computer control and the connecting gear of device systems outside, control panel is used for the control information of indication mechanism control module, and status indicator lamp then is for detection of the residing state of whole process.
Specifically, described illuminator comprises the light-regulator that is connected with lighting unit, and this light-regulator is connected with the mechanism controls unit.Described shooting disposal system comprises video camera, graphics processing unit and the image display that connects successively, and described graphics processing unit is connected with computer control, and as preferred, in the present embodiment, described video camera is ccd video camera.And described transmission system comprises the transmission support that is separately installed with sensor and steady arm, and respectively with the mechanism controls unit be connected support and be connected, and be used for the X/Y job control platform that the control battery moves in directions X and Y-direction.
