Description
Technical Field
[0001] This utility model relates to the field of tray separation and stacking technology, specifically to an automatic tray separation and stacking device. Background Technology
[0002] Trays are instruments used in industrial production to carry and transfer various parts or products. They are widely used in many industries such as electronics, machinery, and food. In large-scale production processes, trays need to go through multiple stages such as conveying, processing, and storage. In order to ensure the continuity and efficiency of production, it is urgent to separate the trays in an orderly manner so that they can enter the processing area individually, and to re-stack the processed trays for storage and turnover. The separation and stacking of trays has become an indispensable part of the production process.
[0003] Traditional tray handling methods rely heavily on manual operation. Before the trays enter the processing area, they must be manually separated one by one. After processing, the scattered trays must be manually re-stacked. This method not only consumes a lot of manpower and increases labor costs, but also has low efficiency, making it difficult to meet the needs of high-speed production. At the same time, during manual separation and stacking, improper operation can easily lead to tray damage or parts falling off, affecting product quality. Fatigue and other factors can also cause operational errors, posing a threat to production safety and seriously restricting the level of automation and overall efficiency of production. To address this, we propose an automatic tray separation and stacking device. Utility Model Content

[0057] PLC control box 22: Located at the front end of the conveyor base 1, it receives instructions to control each mechanism, switches between separation / stacking modes, and ensures the precise and orderly operation of the device.
[0058] Working principle: After the device is started, the PLC control box 22 receives the running command and determines whether the current mode is separation mode or stacking mode according to the preset program. Each mechanism enters the initial working state. When performing the tray separation operation, the stacked tray body 9 is placed on the horizontal support plate 8, located between the two separation cylinders 10. The L-shaped claws 11 support the tray body 9 from below. The lifting cylinder 7 is activated, and the piston pushes the horizontal support plate 8 upward, causing the tray body 9 to rise. At the same time, the guide column slides along the support plate 6 to ensure stability during the rising process. The drive motor 13 on the support frame 12 starts, driving the threaded rod 14 to rotate, causing the fixed guide 16 to slide along the fixed frame, adjusting the bearing plate 18 to be directly above the material tray body 9. The stacking cylinder 17 pushes the bearing plate 18 down, and the vacuum suction cup 19 contacts the uppermost material tray and generates suction force. The vacuum suction cup 19 is used to attach the material tray body 9 to the bottom of the bearing plate 18. The separation cylinder 10 drives the L-shaped claw 11 to retract, releasing the material trays below the uppermost layer. Then, the stacking cylinder 17 drives the bearing plate 18 to rise, completing the single-layer material tray... The tray separates, the support plate 18 moves to directly above the synchronous belt 2, the vacuum suction cup 19 releases the tray, and at the same time the small cylinder 20 pushes the pressing isolation plate 21 to push the tray body 9. At this time, the tray body 9 falls on the synchronous belt 2, and the drive motor 5 drives the transmission roller 3 to rotate through the crawler 4, so that the synchronous belt 2 runs and transports the tray along the conveyor base 1 to the designated processing position. The processed tray is transported by the synchronous belt 2 to the stacking mechanism end. At this time, the device switches to stacking mode, and the horizontal support plate 8 rises to the receiving position under the action of the lifting cylinder 7. The vacuum suction cup 19 is used to hold the tray body 9, and the sliding of the fixed guide 16 is used to transport the tray body 9 to the top of the horizontal pallet 8. At this time, the separation cylinder 10 drives the L-shaped claw 11 to extend and hold the newly transported tray. The lifting cylinder 7 drives the horizontal pallet 8 to rise a certain distance, the L-shaped claw 11 extends to hold the tray body 9, and the lifting cylinder 7 descends, realizing the stacking of trays layer by layer. Throughout the process, the PLC control box 22 dynamically adjusts the actions of each mechanism according to the feedback to ensure that the separation and stacking process is precise and orderly.
