Abstract

A feeding device includes a support mechanism, a movable platform, a driving mechanism mechanism, a clutching mechanism, and two or more holding mechanisms. The movable platform is movably connected to the support mechanism, and loads feed trays stacked together. The driving mechanism drives the movable platform to move relative to the support mechanism. The holding mechanisms are fixed on the support mechanism, and switch from a first position to a second position. When the holding mechanisms are positioned in the first position, the holding mechanisms grasp one feed tray adjacent to a feed tray at a top of the feed trays, and the clutching mechanism clutches the feed tray at the top of the feed trays. When the holding mechanisms are positioned in the second position, the holding mechanisms separate from the feed trays.

Claims

1. A feeding device, comprising:

a support mechanism;

a movable platform movably connected to the support mechanism, and loading a plurality of feed trays stacked together thereon;

a driving mechanism driving the movable platform to move relative to the support mechanism;

a clutching mechanism clutching the feed trays one by one;

at least two holding mechanisms fixed on the support mechanism, wherein when the at least two holding mechanisms are positioned in a first position, the at least two holding mechanisms grasp one feed tray adjacent to a feed tray at a top of the feed trays, and the clutching mechanism clutches the feed tray at the top of the feed trays;

when the at least two holding mechanisms are positioned in a second position, the at least two holding mechanisms separate from the feed trays.

2. The feeding device of claim 1, wherein each of the feed trays defines at least two positioning grooves on opposite sides thereof, the at least two holding mechanisms are engaging in the at least two positioning grooves in the first position.

3. The feeding device of claim 2, wherein each of the at least two holding mechanisms comprises a cylinder and two positioning assemblies connected to the cylinder.

4. The feeding device of claim 3, wherein each of the positioning assemblies comprises a guiding assembly, a positioning member, a connecting member, and an elastic member, the connecting member extending through the guiding assembly and the elastic member and fixed to the positioning member, and the connecting member corresponding to the at least two positioning grooves of the feed tray.

5. The feeding device of claim 4, wherein the guiding assembly comprises a first guiding member and a second guiding member fixed to the first guiding member, the first guiding member defines a guiding hole;
