[0034] Example:

[0035] This embodiment provides a material delivery tray for gear shaft parts, such as Figures 1 to 3 As shown, the tray body 1 includes a rectangular tray body 1, which includes an upper tray 11 and a lower tray 12 connected to each other; the upper tray 11 is provided with a plurality of equally spaced first cylinder support holes 13, and the lower tray 12 is provided with a plurality of second cylinder support holes 14, and the first cylinder support holes 13 and the second cylinder support holes 14 are coaxially arranged;

[0036] An axis part limiter 2 and a plurality of gear limit plates 3 are installed on the tray body 1. An identification vertical plate 4 is provided at each lateral end of the upper tray 11. A pair of wear-resistant strips 5 arranged parallel to the longitudinal direction of the lower tray 12 are installed at the bottom of the lower tray 12. A pair of wear-resistant strips 5 are arranged on the outside of the second through hole 14 of the cylinder support. A guide bearing 6 is installed at both ends of each wear-resistant strip 5. A limit block 7 is provided at the center position of the longitudinal ends of the bottom of the lower tray 12.

[0037] In this embodiment, the shaft part limiter 2 and the gear limiter 3 provided on the pallet body 1 are used to place the complete set of shaft parts and gears required for a single product. A pair of wear-resistant strips 5 on the lower pallet 12 are in contact with the conveying rollers of the automatic transport track to avoid wear of the lower pallet 12 by the conveying rollers during the transmission process. If there is wear, only the wear-resistant strips 5 need to be replaced to reduce maintenance costs. The guide bearings 6 at both ends of the wear-resistant strips 5 match the conveying rollers on both sides of the automatic transport track and are used for automatic guidance during the loading and unloading docking process of the material delivery pallet to improve the operation stability. When the material delivery pallet is running on the automatic transport track, when the visual recognition picking system recognizes the identification vertical plates 4 provided at the horizontal ends of the upper pallet 11, That is, when it reaches one of the material automatic grabbing stations, the limit blocks 7 at the longitudinal ends of the bottom of the lower pallet 12 can be engaged with the stop mechanism of the conveyor roller to stop the material delivery pallet, and then the top of the lifting cylinder push rod on the automatic transport track corresponds one-to-one with the second through hole 14 of the cylinder support and the first through hole 13 of the cylinder support, and the stepped edge of the lifting cylinder push rod is engaged with the bottom surface of the lower pallet 12 to lift the entire pallet body 1. After the entire pallet body 1 is lifted by the lifting cylinder, automatic loading and unloading of parts are carried out, and finally the complete set of shaft parts and gears required for a single product are assembled on the material delivery pallet, and at the same time, it can be docked with the AGV roller for transportation and transported to the assembly line roller for assembly operations.

[0038] As a preferred solution of this embodiment, the gear limiting plate 3 in this embodiment includes a Y-shaped support frame 31, and the Y-shaped ends of the support frame 31 each extend upwardly with a limiting protrusion 32, and a Y-shaped support block 33 extends upwardly from the top center of the support frame 31. The overall Y-shaped structure of the gear limiting plate 3 can not only ensure that the gear is placed firmly, but also reduce its own weight, thereby reducing production costs. The length of the limiting protrusion 32 from the center of the support frame 31 matches the radius of the gear's tooth top circle, and the length of the Y-shaped end of the support block 33 from the center of the support block 33 matches the radius of the gear's hub hole. When the gear is placed on the gear limiting plate 3, the gear's hub hole is mounted on the support block 33, and the Y-shaped structure of the support frame 31 supports the entire gear from below. The three limiting protrusions 32 contact the gear's tooth top from three directions, surround the gear, improve the placement stability, avoid gear displacement during transportation, and thereby avoid the gears from affecting the quality and cleanliness of the parts due to collisions.

[0039] Furthermore, a fixing screw 34 is provided at the bottom center of the support frame 31, and a coaxial mounting through hole 15 is provided on the upper tray 11 and the lower tray 12. A long nut 16 is provided in the mounting through hole 15, and a countersunk bolt 17 is installed in the mounting through hole 15 of the lower tray 12.

[0044] As a preferred solution of this embodiment, the diameter of the second through hole 14 of the cylinder support in this embodiment is larger than the diameter of the first through hole 13 of the cylinder support. The diameter difference between the two forms a stepped structure, which can be matched with the top rod of the lifting cylinder with a stepped end on the automatic transport track, ensuring that the lifting cylinder can lift the material delivery pallet as a whole to avoid falling and ensure production safety.

[0045] As a preferred solution of this embodiment, a pair of anti-collision strips 8 are respectively provided on the two longitudinal side walls of the lower tray 12 in this embodiment. The anti-collision strips 8 are made of polyurethane material to protect the entire material delivery tray from collision damage during operation.

The bottom of the identification plate 4 is fixedly installed in the mounting groove 19, and an identification QR code is provided on the vertical side wall of the identification plate 4. The identification QR code in this embodiment is a metal QR code. The identification QR code of each pallet has a single exclusivity, which is convenient for the visual identification picking system to read. As the unique identification of the pallet, it is bound to the parts during the picking process, which facilitates the tracing of the source of parts in the production process and timely avoids quality problems.

[0047] As a preferred solution of this embodiment, the gear limiting plates 3 in this embodiment include three large-sized gear limiting plates and three small-sized gear limiting plates. The number and size of the gear limiting plates 3 can be adjusted according to work order requirements.

[0048] In this embodiment, the entire material delivery tray, except for the bottom surface of the wear-resistant strip 5, is plated with white zinc for corrosion protection.
