Description

[0002] In modern manufacturing, trays are commonly used carriers for various small parts and electronic components, and their storage and processing efficiency plays a crucial role in the overall operation of the production line.

Second, when the elevator splits stacked trays, it mostly uses simple mechanical separation methods, making it difficult to accurately control the splitting force and sequence, which can easily damage the trays or cause incomplete splitting. Third, insufficient tray positioning accuracy makes it easy for the robotic arm to have grasping deviations when picking up materials, affecting the accuracy of picking up materials and production quality. Fourth, the stacking process of trays after picking up materials lacks orderly control, which may result in unstable stacking, tilting, etc., increasing the difficulty of subsequent processing and safety hazards.

[0042] Please refer to Figures 10 to 12 As shown, the working process of a tray sorting and stacking bin device in this embodiment is as follows:

[0043] The operator pulls the drawer slide to extend the drawer storage mechanism, then places the stacked trays onto the drawer carrier, and initially positions them using the drawer limit side panel and drawer limit vertical bar. Next, the operator pushes the drawer slide and the drawer storage mechanism into the lower rack. Once in place, the drawer locking component activates, inserting the locking pin upwards into the carrier's locking hole to lock the drawer carrier. The lower conveyor mechanism then starts, transporting the stacked trays backwards. At this point, the buffer lifting baffle is in a high position, blocking the stacked trays. When the subsequent lifting conveyor has no trays, the buffer lifting baffle descends, and the stacked trays are continued to be transported backwards until they contact the lifting limit bar, thus completing the transport.

[0044] The lifting and conveying mechanism is activated, and the first lifting platform raises the stacked trays until the uppermost tray is raised to the splitting mechanism. The splitting translation block moves the splitting claws between the uppermost tray and the tray below it. Then, the first lifting platform lowers the remaining trays, with the uppermost tray supported by the splitting claws. At the same time, the descent of the first lifting platform makes room for the lifting platform assembly to move.

[0045] The positioning mechanism is activated, and the corner positioning moving block drives the second corner positioning block to move, pushing the tray against the first corner positioning block to complete the positioning of the tray. At this time, the external robot picks up the material from the tray.

[0046] After all materials are picked up, the lifting platform assembly moves to below the splitting and positioning mechanism; the second lifting platform rises to receive the empty trays after material picking, and the lifting platform assembly moves to below the stacking mechanism. The second lifting platform then lifts the trays, allowing them to stack in the stacking vertical guide rails. As the trays are continuously fed, they are stacked in an orderly manner in the stacking vertical guide rails.

[0047] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.

A tray sorting and stacking hopper device according to claim 9, characterized in that: The stacking mechanism includes stacking components on the left and right sides of the front area of ​​the upper frame; the stacking components include stacking mounting blocks; a flip support block is hinged to the stacking mounting block; the flip support block includes a support part and a limiting part; a return torsion spring is also provided between the flip support block and the stacking mounting block; in the initial position, the top surfaces of the multiple support parts constitute a bearing surface for supporting the tray. The limiting part abuts against the stacking mounting block to maintain the supporting function of the support part; the stacking mechanism cooperates with the upper conveying mechanism to allow the support part to flip upward due to the movement of the tray when the second lifting carrier plate conveys the tray upward. After the tray passes the flipping support block, the support part returns to its initial position under the action of the return torsion spring. The second lifting carrier plate descends, and the tray is placed on the bearing surface of multiple support parts; the stacking mechanism also includes stacking vertical guide strips fixed to the front area of ​​the upper frame, and multiple trays are stacked from the bottom side along the stacking vertical guide strips.
