In SMT production, materials are often used in large quantities and there are many types of materials, so material management is an indispensable part of the entire production management. In SMT manufacturing, whether the required materials can be obtained quickly and accurately directly affects the production efficiency and production cost of the enterprise.

Among them, when a first angle is formed between the material moving member 42 and the fixing member 41, the material moving member 42 opens outward in a horizontal shape so that it can extend under the corresponding material tray, which is convenient for picking out the material tray. When a second angle is formed between the material moving member 42 and the fixing member 41 , the material moving member 42 is perpendicular to the fixing member 41 , so that the material tray can be stably clamped between the two.
