Mode of execution

Embodiment 1:

As shown in Figure 1, the embodiment of the automatic focusing machine comprises a frame 1, mounted on the frame 1 the bottom plate of the above 2 and PLC controller, the bottom plate 2 is provided with a bottom plate 2 the sliding of the sliding table 3, table 3 by the 1st drive device 6 drive, in particular, the bottom plate 2 is provided with two parallel series of guide rail, slider 3 is provided with a matched with the guide rail and the bottom of the guide groove, sliding table 3 by means of a guide rail and a guide chute is slidably mounted on the bottom plate 2 is, 1st driving device 6 is preferably a single-axis drive, single-axis driver driving sliding table 3 horizontal movement.

Frame 1 is provided with one side of the lifting frame 5, a lifting frame 5 is provided with a vertical mobile lifting platform 4, specifically, a lifting frame 5 is fixed on the frame by a bolt 1 of a side, a lifting frame 5 is provided with a vertical slide block 51, vertical slide block 51 and a lifting frame 5 sliding fit, the vertical slide block 51 is fixed on the lifting platform 4, lifting platform 4 by the 2nd driving device 7 drive, 2nd driving device 7 is preferably a telescopic cylinder, a telescopic cylinder drives a vertical slide block 51 the vertical moving.

In order to achieve automatic focusing, sliding table 3 is provided with at least two groups of test fixture, lifting platform 4 is provided with the focusing ring 11,1st driving device 6,2nd driving device 7 and the focusing ring 11 by the PLC controller. The focusing camera module to manual installation is placed in the test fixture is, then manual control operating platform, through the PLC controller to control the operating platform 1st driving device 6 drive the slide table 3 to the focusing ring the camera module 11 the underface, 2nd PLC controller to control the driving device 7 driven lifting platform 4 down, until the focusing ring 11 and the camera module docking complete, PLC controller controls the focusing ring 11 for the Image-capturing module for focusing, at the same time, slide table 3 of the other test fixture can be applied by the manual installation at the same time put to be focusing camera module set, the completion of the Image pickup module focus group, PLC controller will control the focusing ring 11 upstream, and let the sliding table 3 drives the next set of camera module horizontal movement, to the focusing ring 11 to the lower part of the focusing, at this moment the first set of camera module can be taken out. In this way, the whole focusing process only need manual taking camera module, the remaining focusing, the focusing process is finished automatically under the control of PLC controller, the focusing efficiency is high and accurate.

It should be understood, the above description of the specific embodiment used for the interpretation of this utility model, is not used for limiting the utility model. The utility model is extended by the spirit of the change or changes is still in the scope of protection of the utility model.
