[0030] Working principle: Trays are generally used to store precision products (such as chips and tiny parts), and a single tray is usually loaded with multiple products; When in use, first move the movable carrier plate on the first horizontal transport module of the loading unit to the rear end away from its vertical transport module, and place a plurality of (e.g., 20) vertically stacked trays on the movable carrier plate of the first horizontal transport module of the loading unit by manual or external handling mechanism; Move the movable carrier block on the vertical carrier module of the loading unit to a low position, at which point the movable carrier block is lower than the material tray stacked on the movable carrier plate of the first horizontal carrier module of the loading unit; Driving the movable carrier plate of the first horizontal carrier module to move forward until the material tray stacked thereon moves to just above the movable carrier block on the vertical carrier module of the loading unit; Driving the movable carrier block of the vertical carrier module of the loading unit to move upward, thereby moving the stacked trays upward from the movable carrier plate of the first horizontal carrier module; Continue to drive the movable carrier block of the vertical transport module on the loading unit to move up to a high position, and make the stacking gap formed between the two material trays on the uppermost layer consistent with the height of the left material block and the right material block; At the same time, the left cylinder and the right cylinder are switched from the initial contracted state to the extended state, thereby driving the left push plate and the right push plate to move synchronously in the direction close to the material tray, so that the left material block and the right material block installed on the left push plate and the right push plate are simultaneously embedded in the stacking gap formed between the two material trays on the uppermost layer and overlap and contact with the lower surface at the edge of the material tray on the uppermost layer; At the same time, the side push block moving with the left push plate or the right push plate can be pressed and contacted with the side surface of the tray under the action of the spring, so as to realize the clamping and positioning of the tray in the left and right directions, and also avoid damage to the tray; Furthermore, the left material dividing block, the right material dividing block and the lower pressing block can cooperate to realize the clamping and positioning of the material tray in the vertical direction, thereby further improving the positioning accuracy; The movable carrier block of the vertical transport module on the loading unit is driven to move downward. At this time, the material tray on the uppermost layer cannot move upward with the left material dividing block and the right material dividing block, thereby separating the material tray on the uppermost layer from the material tray below it; Next, the vertical cylinder 20 is used to place the strip plate and the horizontal carrier plate that moves with it at the low position of its stroke, and then the cylinder 15 drives the beam plate to move from the rear end to the front end until the horizontal carrier plate that moves with it moves to the bottom of the material tray between the left material dividing block and the right material dividing block. At this time, there is a certain gap between the upper surface of the horizontal carrier plate and the lower surface of the material tray, and then the vertical cylinder 20 is used to drive the strip plate and the horizontal carrier plate that moves with it to move up until the upper surface of the horizontal carrier plate contacts the lower surface of the material tray, thereby realizing the stable connection of the separated material tray; Next, the left cylinder and the right cylinder are switched from the extended state back to the contracted state so that the side push block and the lower pressure block release the clamping of the material tray, and then the left cylinder, the right cylinder, the rear cylinder and the front cylinder are switched from the contracted state to the extended state at the same time, thereby driving the side push block, the lower pressure block, the movable push block and the fixed push block to move toward the material tray from four directions at the same time until they are in contact with the four side surfaces of the material tray respectively. The side push block and the movable push block can realize the elastic clamping and positioning of the material tray under the action of the spring, thereby protecting the material tray and improving its position accuracy, so as to facilitate the subsequent picking of the product in the material tray and avoid the situation in which the material tray is deflected by external force and the position accuracy of the internal products is affected during the process of picking up the product in the material tray; When the products in the tray on the horizontal carrier are picked up, the left cylinder, the right cylinder, the rear cylinder and the front cylinder are switched from the extended state to the retracted state so that the side push block, the lower pressure block, the movable push block and the fixed push block release the clamping of the tray; Then, the movable base plate is moved to the top of the tray that has picked up the product through the second horizontal transport module of the transfer unit, and then the transfer cylinder is switched from the initial contracted state to the extended state so that each vacuum suction cup on the movable base plate is in suction contact with the upper surface of the tray, and then the movable base plate with the tray adsorbed is moved to the top of the movable carrier block on the vertical transport module of the unloading unit through the second horizontal transport module of the transfer unit, and the vacuum in the vacuum suction cup is disconnected so that the tray falls onto the movable carrier block of the vertical transport module; In this reciprocating process, when the material trays on the movable carrier block of the unloading unit are stacked to a certain number, the movable carrier plate on the first horizontal transport module of the unloading unit is moved to the bottom of its movable carrier block, and the movable carrier block of the vertical transport module on the unloading unit is driven to move downward until the stacked material trays thereon are transferred to the movable carrier plate on the first horizontal transport module, and then the movable carrier plate on the first horizontal transport module of the unloading unit is moved to the rear end away from its vertical transport module, and several (e.g., 20) vertically stacked material trays are moved away by manual or external transport mechanisms.

[0031] When the above-mentioned tray loading and unloading mechanism is adopted, it can not only automatically and batch-load the products in the tray, but also automatically transport and unload the empty trays after loading, thereby improving the efficiency and stability of production and processing; further, the stacked trays containing products can be automatically separated one by one and the separated trays can be stably connected, and the stability of the trays and the products in the trays can be guaranteed throughout the whole process.

[0032] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
