[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Pallets are the medium that transforms static goods into dynamic goods. They are a loading platform, and a movable platform, or in other words, a movable floor. Even goods that lose their flexibility when placed on the ground can immediately become mobile and flexible once they are loaded on a pallet, because the goods loaded on the pallet are always ready to be put into motion.

[0004] During the production process, the engine body needs to be transported using corresponding positioning pallets. Currently, positioning pallets are mostly used for positioning, transporting and material distribution in industrial automation. In scenarios such as automated production lines, logistics warehousing systems and sorting centers, the pallet needs to be docked with the production line. After docking, the body on the pallet (such as shell and cover parts) is transported along with the production line. Currently, some pallets are prone to inaccurate docking positions when docking with the production line, resulting in low docking efficiency. Collisions may occur during docking, causing partial structural damage. In addition, the accuracy of the body position needs to be ensured during transportation to prevent the body from shifting or falling before subsequent production and processing can be carried out. Although some pallets can currently be transported and positioned, their positioning accuracy and stability are limited, and only rough positioning can be achieved. They are prone to shaking during transportation, which will cause deviations in the subsequent processing and production positions. In addition, the size of the body that can be positioned is limited and cannot be flexibly adjusted, resulting in insufficient applicability. Utility Model Content

One side is the large flat surface of the shell and cover, which is supported by a circle of several pads (ground flat after assembly), and the pads are fastened to the clamp body with countersunk screws. The two pins, one is a cylindrical pin, and the other is a diamond pin (chamfered pin). The long axis of the diamond pin is perpendicular to the center line connecting the two pins, and the center distance of the two pins is equal to the center distance of the positioning pin holes of the shell and cover.). The positioning pin 3 is a fixing device used to limit and position the body, usually a cylindrical or conical pin, and its function is to prevent the body from displacement or rotation during installation or processing.

[0033] The positions of the first positioning member 2 and the second positioning member 10 can be flexibly adjusted. Several screw holes are provided on the tray body 4. The second positioning member 10 is installed first, and the second positioning member 10 is connected to the tray body 4 by the second fixing bolt 11.

[0036] Instructions for use: First, the pallet is positioned and docked with the production line through the docking plug 1, auxiliary guide groove 7, anti-collision roller 8, and movable guide groove 6. Next, one surface of the machine body is close to the first positioning part 2 and contacts it. At the same time, the machine body is adjusted to dock with the positioning pin 3 to achieve further precise positioning. The "two pins and one face" combination design fully restricts the six degrees of freedom of the machine body to ensure that it is fixed on the pallet. The empty pallet is loaded at the initial position and docked with the conveyor. The machine body is transported to the machine body processing position. After processing, the pallet is transported to the unloading position and unloaded by sinking the pallet. After unloading, the pallet reaches the pallet sinking position. After transportation, the pallet is reset, rises to the initial position and continues to load, and repeats. This makes the entire positioning and material distribution process more accurate and efficient, thereby improving the overall efficiency of the production line and product quality.

[0037] This positioning pallet can be used to complete the cyclic conveyor conveyor system at each workstation on the production line. Specifically, the positioning pallet uses two pins and one side to perform the initial positioning, completing the tightening of the tile covers at three workstations. The tile covers are the tiles on the vehicle. After completion, the body is removed and the positioning pallet returns to the initial positioning point via the lower roller to wait for the second body to be positioned. After the first completed body completes the subsequent work, it returns to the loosening of the tile covers. This positioning uses protruding blocks for rough positioning to complete the loosening of the tile covers.

Taking the positioning of the body as an example, a guide is provided by the first positioning member 2, and positioning is performed by the cooperation of the first positioning member 2 and the positioning pin 3. The positioning pin includes a diamond pin and a cylindrical pin. This positioning method is used to position the top surface of a body of a certain model; during positioning, the outer side surface of the first positioning member 2 provides a guide for the body. After the body reaches the corresponding position, a diamond pin is installed on the upper part of the first positioning member 2 at one end, and the diamond pin passes through the corresponding pin hole on the body. A cylindrical pin is installed on the upper part of the first positioning member 2 at the other end, and the cylindrical pin also passes through the corresponding pin hole on the body. Both the diamond pin and the cylindrical pin are at one end of the upper part of the first positioning member 2, thereby completing the positioning of the body.

[0041] Example 3:

[0042] In a typical implementation of this embodiment, a positioning tray assembly is provided. Taking the positioning of the body as an example, the body is positioned by cooperating with the first positioning member 2 and the positioning pin 3. This positioning method is used to position the bottom surface of another model of the body.
