After the manipulator takes out the material from the material tray of the feeding station of the feeding mechanism, it moves the material and places it in the material tray after the load, support and limit correction at the above-mentioned material picking station. After the material tray is full of material, the blocking assembly releases the material tray, and the material tray flows into the cleaning station.

When the trays at the feeding station are taken out, the stacked trays loaded with materials are sent in again, and the cycle is repeated. By stacking the trays one by one, the continuous supply of materials is achieved, and the stability and continuity of the feeding are ensured. The utility model sets a tray transport mechanism at a side edge perpendicular to the machine platform. The tray transport mechanism includes a transmission line and a return line arranged in parallel and at intervals, wherein the transmission line is used to linearly transmit the trays loaded with materials to different processing stations for assembly and processing, and the return line is used to reversely transmit the empty trays that have been processed on the transmission line and have taken out the materials. The transmission line and the return line are used to realize the recycling of the trays, and the continuous stability of the feeding is ensured.At the same time, a material picking station and a cleaning station are provided on the material tray transmission channel of the transmission line. A guide plate, a blocking assembly and a top supporting assembly are provided at the material picking station. After the transmission line transmits the empty material tray to the material picking station, it slides into the gap between the guide plate and the transmission belt, and is limited by the upper and lower guides of the guide plate. At the same time, the blocking assembly blocks the subsequent material tray from flowing into the material picking station, and then the top supporting assembly lifts and supports the material tray from below to ensure the material tray load and position accuracy. After the manipulator takes out the material from the material tray of the feeding station of the feeding mechanism, it moves the material and places it in the material tray after the load, support and limit correction at the above-mentioned material picking station. After the material tray is full of material, the blocking assembly releases the material tray, and the material tray flows into the cleaning station. After being blocked and limited by the blocking assemblies arranged on the front and rear sides of the cleaning station, the cleaning mechanism located above the cleaning station cleans the material with plasma gas to ensure the surface cleanliness of the material during subsequent assembly and processing, thereby improving the assembly and processing quality.
