Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to Following embodiments.
Embodiment
As shown in Figure 1, 2, the automatic testing stand frame system of wireless charging system for electric automobile includes in rack braced frame Part 2 under part 1 and braced frame, upper mounting plate 3, lower platform 4, the support connecting frame 5, centre being mounted in the braced frame Connecting plate 6, lead screw and bearing 7, XYZ axis servo motor 8, movable pedestal 9, controller 12 and reseting sensor 11.The set System support has power analyzer 13 and rack host computer 14, and rack bottom is provided with locking idler wheel 10.
Part 1 includes the upper lower platform for placing coil system in braced frame, need to be considered when coil working in ambient enviroment Influencing each other between metal and generation magnetic field, therefore upper part integrally uses bakelite material.Part 2 is apart from work under braced frame Platform farther out, influences each other smaller negligible with magnetic field, compares upper frame, lower frame is subjected to more weight, therefore lower part The whole aluminum alloy materials using high-intensitive light weight
Upper mounting plate 3 is mounted on the top of part 1 in braced frame, fixed, for placing receiving coil.Meanwhile being The drift condition between transmitting coil on the receiving coil placed thereon convenient for eye-observation and lower platform 4, comprehensively considers magnetic Field influences, and upper mounting plate 3 is using transparent glue doubling steel glass and posts graduated scale.Lower platform 4 is placed in braced frame in part 1 Face is connected by support connecting frame 5 with middle connecting plate 6 for placing transmitting coil.Both it needs to do insulation processing, unite One uses bakelite material.
Lead screw and bearing 7 are fixedly installed under middle connecting plate 6, lead screw uses ball-screw, and precision is higher, can guarantee Offset error is in 2mm or so.Meanwhile including three servo motors, it is fixed on movable pedestal 9, is respectively disposed on XYZ axis three On a direction, by the connection of ball-screw and bearing 7, middle connecting plate 6 is driven to move together with lower platform 4 thereon, from And realize the clearance offsets between upper lower platform, and be directly controlled by PLC12.Support connecting frame 5 is in arch bridge type in structure, and totally four It is a, it is symmetrically distributed in four angles and carries out uniform load-bearing, middle connecting plate 6 and movable pedestal 9 are all made of high-strength alloy thickness steel Plate has certain mass, can mitigate shaking when lower platform moves integrally.9 bottom of mobile base is equipped with two X-axis and Y-axis sides To shifting sledge, the setting of sliding rail ensure that the whole ride comfort mobile in X/Y plane of lower platform 4.
Host computer 14 can simultaneously and controller 12 and the progress data communication of power analyzer 13.The host computer interface can be set XYZ coordinates of targets, while can realize that the automatic running of rack and data acquire, it is and each for the spacing distance of automatic running It is spaced residence time, all programmable.Controller 12 uses programmable logic controller (PLC), is able to achieve the data with host computer 14 Real-time collected 8 position data of servo motor is sent to host computer 14 by communication.Power analyzer 13 can real-time measurement coil The current and voltage signals of system input and output, and data are transmitted to host computer 14 in real time.
Three reseting sensors 11 are separately positioned on origin position defined in tri- axis of XYZ and are used for using photoelectric sensor 4 position of lower platform is resetted.When the sheet metal being arranged on movable pedestal 9 slides into origin, sheet metal is passed right through Sensor, the light between two sides are blocked, and photoelectric sensor output photoelectric signal is to controller 12, and lower platform 4 exists at this time Origin is resetted and is completed.
When it is implemented, operating mode is roughly divided into two kinds:
1, when only need to specific to space some offset point carry out the test of coil whole efficiency when, only need to be at 14 interface of host computer Coordinates of targets, such as offset X-direction 200mm, Y-direction 150mm, Z-direction 150mm is set in advance, then clicks starting operation, on Data command is sent to controller 12 by position machine 14, after controller 12 receives instruction, is directly controlled to XYZ axis servo motor 8 System, motor are operated according to setting speed, drive bottom movable pedestal 9 to carry out the sliding of X/Y plane on the slide rail, while in silk Z axis is risen under the lifting of thick stick and bearing 7, and final lower platform 4 is displaced to coordinates of targets under the drive of support connecting frame 5, The transmitting coil that the receiving coil and lower platform that upper mounting plate is placed at this time are placed reaches target offset, and power analyzer starts to measure Current and voltage signals at this time finally obtain the data such as input-output power and transmission efficiency, and are stored in table, and test is completed.
2, when needing to carry out the test of coil whole efficiency to all the points in given plane or spatial dimension, host computer 14 Automatic running pattern, the trajectory model of the operation can be started are as follows: using Z axis as most higher level, X-axis is secondary, and Y-axis is most junior, Constant, all the points of the complete X/Y plane of first traversal of Z axis height are first fixed, then are lifted Z axis, continue to traverse next corresponding high The X/Y plane of degree, until space, all offset points all traverse completion, and entire test can be completed.When on X/Y plane, similarly press X-axis is first fixed according to priority, all the points of the complete corresponding Y-axis of first traversal are further added by X-axis offset, continue to traverse next corresponding X Under Y, until all offset points of the plane all traverse completion, the standoff distance between each point can pass through with the residence time Host computer 14 is set.The mode is realized by controller programming, need to only call open on host computer 14 in practical applications Dynamic, once test starts, power analyzer 13 and controller 12 can the corresponding coil currents of each Dislocations of real-time Transmission Voltage signal receives data with corresponding XYZ coordinate, host computer 14, and real-time display is simultaneously stored in table.
