As shown in fig. 10 to 12, the specific structure of the automatic gripping mechanism is: the automatic grabbing mechanism 5 comprises a moving frame 51, a transmission assembly 52 arranged on the moving frame 51 and a positioning piece arraying grabbing assembly 53 arranged at the lower end of the moving frame 51, wherein the positioning piece arraying grabbing assembly 53 comprises first gripper assemblies 54 oppositely arranged at two sides of the lower end of the moving frame 51, second gripper assemblies 55 arranged between the first gripper assemblies 54 and a lifting driving mechanism 56 for driving the second gripper assemblies 55 to lift and move, and the position of the second gripper assemblies 55 is changed through the lifting driving mechanism 56 so that the multifunctional automatic grabbing mechanism can switch to grab a single channel for clamping the backboard between the first gripper assemblies 54; or a dual channel grip that clamps the backing plate between the first gripper assembly 54 and the actuating second gripper assembly 55. The product which is positioned on the positioning sheet arranging machine is grabbed and transmitted to the upper surface of the back plate glass of the vacuum platform through the grabbing mechanism, the product is released to the platform, and then the product and the back plate are adsorbed together through vacuum adsorption. Therefore, the scheme can switch single-channel grabbing or double-channel grabbing according to the preset positioning sheet arrangement. Thereby effectively improve the efficiency of snatching the transport, its switch is simple moreover, and automatic switch only needs to rise the second tongs subassembly that will be located between the first tongs subassembly through lift actuating mechanism and can switch into the single channel and snatch. The method is designed and produced under the current large environmental trend that the requirement on the coating yield is higher and higher, and is very practical for coating products with strict requirements on multiple specifications and sizes, mass production, short period, less pollution, high precision, high quality and the like.

Snatch mechanism branch single channel and binary channels, the product washs according to single channel or binary channels, is decided according to the product size, and the size is big on the large side only can the single channel transmission, and the size is little on the small side, can the binary channels, and also the cleaning machine can once wash two rows of products to arranging the piece locating machine, snatchs the mechanism and also can once snatch two rows of products to backplate glass, and the binary channels snatchs is in order to improve the takt, reduces small glass's the number of times of snatching.
