Abstract: A feeding device includes a support mechanism, a movable platform, a driving 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.

Abstract: A scale includes a stationary bracket, a movable bracket, a linear displacement sensor and a plurality of the resilient mechanisms. The movable bracket is disposed opposite to the stationary bracket. The linear displacement sensor is disposed between the stationary bracket and the movable bracket. The resilient mechanisms are disposed between the stationary bracket and the movable bracket. Each resilient mechanism includes a limiting shaft, a sleeve movably sleeved on the limiting shaft and a resilient member received in the sleeve. The limiting shaft is fixed to one of the stationary bracket or the movable bracket, and the sleeve is fixed to the other. The resilient member is elastically deformed by resisting a free end of the limiting shaft. The linear displacement sensor registers a displacement of the movable bracket.
