Detailed description of the invention
Enforcement to core board measurement jig described in the utility model below in conjunction with the accompanying drawings is described in detail; so that the advantages and features of utility model can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made and apparent clearly defines.
As shown in Fig. 1-1,1-2, the present embodiment vapour liquid crystal instrument for vehicle general purpose core core measurement jig includes that the 4th, base the 1st, auxiliary stopper plate the 2nd, depression bar the 3rd, pressing plate tests probe the 5th, quick clip the 6th, action bars the 7th, guide rod the 8th, linear bearing 9 and the equipment control panel 10 being arranged in base；Place auxiliary stopper plate 2 above base 1, be used on auxiliary stopper plate 2 placing core board A to be measured.The upper plane of base 1 is vertically fixed and is connected guide rod 8, and guide rod 8 slides up and down formula and coordinates linear bearing 9, and linear bearing 9 is fixing with pressing plate 4 to be connected, and pressing plate 4 is perpendicular with guide rod 8.Pressing plate 4 moves up and down with linear bearing 9, controls sliding up and down of test probe 5, pressing plate 4 is fixedly connected several depression bar 3, and depression bar 3 is perpendicular to pressing plate 4, and lower the rectifying of depression bar 3 treats survey core board A.
Connecting test probe 5 vertically fixed by pressing plate 4, and test probe 5 is arranged down, and it is down just to board under test A.Briquetting 11 is placed on pressing plate 4.
The upper end fixed installation bearing 12 of guide rod 8, bearing 12 is provided with upper and lower two support arms 13, and lower branch arm 13 forms vertical guide hole, and this vertical guide hole slides up and down cooperation quick clip 6, and the lower of quick clip 6 is rectified to briquetting 11.The upper end of quick clip 6 is rotatably assorted action bars 7.As Figure 1-1, before action bars 7 is not operating, it is put on upper branch arm.After action bars 7 rotates, departing from upper branch arm, and being pressed downward against quick clip 6, quick clip 6 moves downward along lower branch arm.
Just being rotated from top to bottom by action bars, driving the quick clip on tool top to be pressed downward against, quick clip is guided by linear bearing and the guide rod being fixed on base being connected on pressing plate, can press down at a vertical direction；Quick clip and guide rod, matched by the pressing plate at middle part and the linear bearing being fixed on pressing plate, and the former is responsible for transmission operation functional realiey, and the latter is responsible for direction positioning.Pressure briquetting is pushed up downwards in the lower end of quick clip, briquetting, pressing plate, depression bar, test probe and linear bearing is made to move downward, after motion puts in place, depression bar is downwardly against core board to be measured, it is located, and tests the test point to core board for the probe and measure, realized the transmission of signal by probe, equipment control panel bottom probe connection, it is achieved final detection function.
By depression bar and auxiliary stopper plate in order to position core board PCBA to be measured, meanwhile, probe is contacted by the I/O pin and test point with core board, it is achieved the offer of test signal and power supply, probe is connected by inner lead with equipment control panel, it is achieved the detection function of resulting device.
Equipment control panel is provided with TF card socket, serial ports, USB2, USB1, network interface, corresponding, and the side of base forms opening corresponding thereto, so that each socket of equipment control panel communicates with the external world.Network interface, by the external netting twine of LAN8720 to PC, configures computer fixed ip address, and it is whether normal that core board ping this address detects network communication.USB port is in order to read USB flash disk content.Serial ports passes through MAX3232 internal loopback, and wherein serial ports 2 is for carrying out communication, bidirectional transmit-receive with MCU.TF card socket is in order to read TF card content.
Base has a face tilting upward, and this face is installed panel, and panel is connected with equipment control panel 7.As in figure 2 it is shown, panel comprises front panel POWER indicator lamp, LED signal lamp, key switch, power switch and 7 cun of liquid crystal displays and touch-screen.Power switch drives the power supply of core board work in order to provide.Whether normal display screen is in order to the LVDS signal or rgb signal showing output.In the present embodiment, switch key 8, instruction LED 8, switch 2.
Fig. 3 shows that this enforcement row detection tool is perfect by software extensions, can possess up to 15 functions.
Fig. 4 shows the functional module of this detection tool equipment control panel, by block diagram it is known that reserved affluent resources in this Control System Design, possess the functional requirements such as display, storage, loudspeaker, clearing lamp, KEY, UART, CAN communication, USB, Ethernet, TF card.
Core board is positioned by the present embodiment measurement jig by base, probe, and tool can carry out voltage detecting, SD burning, 3 kinds of functions of USB burning to core board, and concrete operations mode is as follows:
1st, voltage is detected
POWER detection module can detect the magnitude of voltage of each project on core board, and can redden process when magnitude of voltage is abnormal, passes through to show for green when normal.
2nd, SD burning
SD detection module is responsible for programming system in emmc, but premise is in addition to outside USB module, and other module projects must be all by just carrying out this module (can limiting and remind in program).
3rd, USB burning
Scorification silk so that the core board of burning can directly start from emmc without dial-up, and this step is the final step of all detections, it is necessary to wait until other detection projects all by just carrying out (can limiting and remind in program).
Owing to core board veneer cannot work alone, therefore, the utility model is individually for the hardware configuration of core board, makes measurement jig and tests 15 test points on core board, to detect whether core board can normally use.
