In the present invention, when the left mounting module 7 is mounting, the CCD visual positioning module 9 moves to the right, and when the right mounting module 8 is mounting, it moves to the left. The left and right mounting are performed alternately, respectively, and the mounting position can be continuously mounted, thereby better realizing fast and high-precision mounting, having a good operating effect, and being easy to be widely promoted.

[0050] The beneficial effect of the present invention is that compared with the prior art, in the present invention, the high-speed visual positioning and dual-station flexible mounting device can be arranged on an automated production line and electrically connected to an external control device. The first material conveying device 5 and the second material conveying device 6 are used to convey mounting materials. The moving work bracket on the production line places the pre-mounted object on the vacuum adsorption platform 4, and then the control device controls the Y-axis motion module 3 to drive the vacuum adsorption platform 4 to move back and forth so that the pre-mounted object moves to the bottom of the CCD visual positioning module 9. After the CCD visual positioning module 9 takes a photo for positioning, it transmits the data coordinates of the pre-mounted object to the control device, and the control device transmits the information to the left mounting module 7 and the right mounting module. 8. At this time, the left mounting module 7 and the right mounting module 8 move to the two ends of the material respectively, absorb the mounting materials of the first material conveying device and the second material conveying device respectively, and then mount them on the pre-mounted objects in a left-right order. The CCD visual positioning module 9 moves left-right after taking pictures to avoid the positions of the left and right mounting modules 8 during mounting. Through the above-mentioned settings, the left mounting module 7 and the right mounting module 8 and a CCD visual positioning module 9 are simultaneously placed on the same X-axis motion module 2. By the left mounting module 7 and the right mounting module 8 on both sides working alternately, the CCD visual positioning module 9 is alternately positioned, which effectively saves the movement distance and equipment space, and greatly improves the speed and precision requirements of mounting.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
