Description

Technical Field

[0001] This utility model relates to the field of toothbrush manufacturing technology, and in particular to an automatic toothbrush handle feeding device. Background Technology

[0002] Traditional toothbrush manufacturers currently use manual brush placement and material handling for feeding, which is slow, has low automation, and results in high labor intensity. There is an urgent need for digital and intelligent improvements to the toothbrush feeding method. Chinese patent CN216334654U proposes an intelligent feeding toothbrush manufacturing equipment. Addressing the problem of uneven arrangement caused by finished toothbrushes falling from the packaging, it designs an automatic toothbrush sorting and arrangement device to ensure that toothbrushes are neatly arranged in the semi-finished product box, facilitating subsequent packaging and reducing worker labor intensity. Chinese patent CN221241997U discloses an intelligent feeding toothbrush manufacturing equipment, proposing a chain conveyor device with toothbrush handle recognition and a rotating mechanism. This device can automatically feed toothbrush handles through recognition, positioning, and detection functions, ensuring fast and accurate feeding. Both of the above patents improve the toothbrush handle feeding mechanism. However, Chinese patent CN216334654U, while using a conveyor belt for horizontal toothbrush transport, still suffers from some toothbrushes not being neatly arranged due to randomness. Chinese patent CN221241997U only addresses the toothbrush handle feeding and conveying section, without considering the structure from the toothbrush handle to the conveyor belt. Existing technologies suffer from low toothbrush handle feeding accuracy and incomplete automatic feeding mechanism design. Therefore, a more stable, accurate, and highly automated automatic feeding system needs to be designed.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The bottom of the toothed handle feeding pallet bin 1 and the empty pallet recycling bin 5 are respectively equipped with a device for fixing the AGV transport trolley. The AGV transport vehicle 6 carries empty pallets 20 and transport trays 7. The toothbrush feeding pallet robot 2 and the empty pallet recycling robot 4 realize the automatic feeding function inside the toothbrush feeding pallet bin 1 and the automatic empty pallet 20 recycling function inside the empty pallet recycling bin 5, respectively. This makes the toothbrushes neatly arranged inside the toothbrush feeding pallet bin 1 and the empty pallets 20 neatly recycled inside the empty pallet recycling bin 5. This reduces the labor intensity of workers and realizes lean and automated feeding operations. The AGV transport vehicle 6 transports materials and recycles empty pallets 20, which not only meets the needs of flexible, multi-variety, small-batch automatic feeding production, but also adapts to the needs of large-scale production lines.

[0044] The structural device includes a robotic arm 24, a tray buckle 25, and a robotic arm actuation cylinder 26. The robotic arm actuation cylinder 26 drives the robotic arm 24. The end of the robotic arm 24 is connected to the tray buckle 25, which holds the empty tray 20. The movement of the robotic arm 24 drives the empty tray 20 to move.

[0045] The pallet transfer device 3 includes a second motor 36, a second conveyor belt 32, a slide rail 29, a second slider 30, an extension arm 31, a telescopic three-bar cylinder 33, a rotary cylinder 34, and a three-section vacuum suction cup 35.

[0046] The second motor 36 drives the second conveyor belt 32, causing the second slider 30 on the second conveyor belt 32 to rotate along the slide rail 29. An extension arm 31 is fixed on the upper surface of the second slider 30. A telescopic three-bar cylinder 33 is fixedly installed at the end of the extension arm 31. The telescopic three-bar cylinder 33 drives the rotary cylinder 34 to rise and fall.
