[0047] The utility model designs an automatic material receiving and testing machine for lens assembly, which realizes automatic cyclic feeding of material trays, automatic pressure maintenance, material throwing detection, material tray stacking and empty material tray stacking supply transfer, and realizes automatic batch and efficient material unloading. The utility model is arranged at the end of the lens automated assembly production line, and its function is to automatically unload and store the assembled lens accessories in batches. At the same time, before batch unloading, the lens frame and lens assembly complete the pressure maintenance process, the detection process, and the defective material throwing process. The pressure maintenance process improves the assembly quality of the lens frame and lens. After the defective assembly materials are screened out through the detection process, the defective materials are taken out and thrown away separately. Multiple processing processes are integrated into one, and the automatic and efficient unloading of the assembled lens accessories is realized, and the unloading yield rate is effectively guaranteed. In addition, based on the processing technology of using material trays as transport carriers in the automatic assembly line for lens accessories, the utility model also has a transmission line and a return material line arranged in parallel and at intervals as a material tray transmission mechanism, and the transmission line drives the material tray and its materials to automatically complete the above-mentioned pressure holding, detection process and unloading process. When the material in the material tray on the transmission line is taken out, the empty material tray is transferred to the return material line through the material tray transfer component, and the empty material tray is reversely transmitted to the front end of the automated assembly line through the return material line to reload the lens frame to be assembled, thereby realizing the automatic circulation feeding of the material tray; in addition, the material receiving mechanism of the utility model supplies stacked empty material trays at the tray placing station through the internal circulation method of the material tray, and the stacked empty material trays are transmitted inwardly to the top of the stacking tray support block through the material tray conveyor belt below, and the stacking tray support block lifts and supports from the bottom and drives the stacked empty material trays to move upward to supply The material in the material tray on the transmission line is taken out by the material taking robot and moved to the empty material tray at the closing station. After the empty material tray is full of materials, the material tray lifting arm takes out another empty material tray from the tray placing station and stacks it on top of the above-mentioned material tray full of materials, and the cycle continues. At the closing station, automatic material unloading and batch storage are realized in the form of material tray stacking. When the stacked material trays at the closing station reach the preset number, the stacking tray support block there drives the material tray to descend, and the stacked material tray filled with materials is placed on the material tray conveyor belt below, which is transmitted in a straight line from the inside to the outside of the machine through the material tray conveyor belt for material retrieval. By stacking the empty material trays and the material trays one by one, the storage and unloading of materials is realized, and the automatic circulation supply of the material trays is realized, which effectively increases the unloading capacity, saves the material changing time, and improves the unloading efficiency. At the same time, the utility model also has a correction component at the closing station. When stacking trays at this station, the correction component is used to correct and limit the position of the trays, thereby ensuring the relative position accuracy of the trays during stacking and avoiding situations such as material falling and damage.
