Description

TECHNICAL FIELD

[0001] The utility model relates to material conveying technical field, especially relate to a material tray feeding device. BACKGROUND

[0002] The material tray feeding device is a device used in an automatic production line or a material conveying system, mainly used for conveying material trays from a storage area to a production line or a processing device.

[0003] The conventional material tray feeding method usually relies on manual operation, which is low in efficiency and prone to errors. With the development of industrial automation technology, the material tray feeding device gradually develops towards automation and intelligence. For example, the Chinese utility model patent with the announcement number CN221115929U discloses a discharging mechanism for a coil holder, which comprises a rack, a material conveying assembly and a material clamping assembly. A pair of discharging racks are arranged on both ends of the rack, and a material waiting area is formed between the pair of discharging racks. The discharging racks are used to store storage boxes, and first limiting air cylinders are arranged on both sides of the discharging racks. The periphery of the storage boxes is movably abutted by the two first limiting air cylinders, so that the storage boxes are at a preset height in the discharging racks. After a plurality of storage boxes are sequentially stacked in one of the discharging racks, the feeding disc of the material conveying assembly can drive the single storage box to be sequentially conveyed to the other discharging rack. When the storage box moves to the material waiting area, the clamping jaws of the material clamping assembly can orderly place the grasped coil holder in the storage box. After the storage box is filled with coil holders, it is sent to the other discharging rack for stacking and storage. Finally, the feeding disc is reset and moved to the lower side of the starting discharging rack to perform the next group of actions.

[0004] The discharging mechanism for the coil holder has low material tray feeding efficiency. The feeding disc needs to move the storage box from the first discharging rack to the material waiting area, complete the coil holder tray filling, and then move to the second discharging rack. Finally, the feeding disc returns to the first discharging rack. The feeding disc has a long moving path, a long reset idle stroke time, and the material clamping assembly needs to be stopped for a long time, which increases the cycle time, cannot quickly supply the material tray, and affects the overall production efficiency.
