When the transfer robot takes the material tray with the detected second surface of the product out of the material tray translation mechanism, the transfer robot takes the material tray with the detected second surface of the product out of the material tray translation mechanism and puts the material tray into the bidirectional material tray turnover mechanism; the material tray is turned over by 180 degrees through the bidirectional material tray turning mechanism to obtain the material tray with the first surface facing upwards after the material tray is turned over positively and negatively, and the material tray is taken out from the bidirectional material tray turning mechanism by the transfer robot and placed into a material discharging position.
The utility model is mainly designed in such a way that the turnover of the whole material tray is realized, the switching of the material trays on the front side and the back side of the material can be satisfied, the detection of the front side and the back side of a product is facilitated, and the conveying, turnover and detection efficiencies are greatly improved;
meanwhile, only a material tray needs to be replaced, compatibility to different products is strong, and the machine type is replaced quickly; because the whole material tray is adopted for overturning, the material tray is hardly influenced by the specification and the size of materials (such as lenses), only the corresponding material tray needs to be changed, and the product surface defect detection equipment can be compatible with different products, especially can be completely compatible under the conditions of different specifications and sizes of similar products; therefore, the machine type can be replaced quickly when different products are detected, the equipment acquisition cost and the equipment storage management cost of a production and processing manufacturer are effectively reduced, and the method is suitable for popularization and application.
Secondly, the cameras can move in the X/Y direction through the material carrying platform module, and a plurality of cameras are arranged along the X axis, so that multi-station continuous camera detection is realized, and a plurality of cameras are in multiple positions, so that a plurality of defect items of the whole disc product can be detected simultaneously, and the detection efficiency is effectively improved; the multi-station camera detection mechanism can be designed to be compatible with different products, and particularly can be completely compatible under the conditions of different specifications and sizes of similar products; only the height of the camera needs to be adjusted.
Moreover, its charging tray translation mechanism removes the setting of seat, elevating gear and synchronous transport arm through translation bed frame, translation drive arrangement, translation, especially, translation drive arrangement removes the electric jar for the X axle, and elevating gear is including motor and cam, realizes accurate translation, lift control to the tray, is favorable to promoting detection or machining precision.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
