Each adsorption groove is connected to a vacuum generator, a control valve and a purification device, and each adsorption groove can be controlled separately. When the controller in the adsorption platform receives the specification information of the product, the controller opens the corresponding adsorption groove according to the specification information.

[0056] When loading, the tray is pulled out and the raw material tray containing the product is stacked on the tray. After loading is completed, the tray is pushed into the loading and unloading rack along the slide rail assembly. During the pushing process, the side baffle and the feed limit block limit the raw material tray so that the raw material tray can be neatly arranged on the loading position.
