Two of the six L-shaped limiting blocks are located in the middle of the inner side of a pair of corresponding lower frame sides, and the remaining four are located in pairs in the middle of the inner side of another pair of corresponding lower frame sides, with a gap between them. The midpoint between the two pairs coincides with the midpoint of the corresponding two lower frame sides. The horizontal plate of each L-shaped structure is fixed on the connecting base plate, and the vertical plate of the L-shaped structure is adjacent to the upper and lower frame sides. The two limiting posts are respectively set outside the two L-shaped limiting blocks on the same frame side, fixed on the connecting base plate, and respectively set close to a pair of lower frame sides, and are symmetrically set along the midpoint.

[0027] The beneficial effects of this utility model are:

[0028] 1. This utility model provides a logistics carrier for the entire production process of shell workpieces. Through the configuration of the connecting base plate and the workpiece limiting component, it can be adapted to up to 10 different types of shell workpieces, realizing the universality of the logistics carrier for shell workpieces. At the same time, its connecting base plate and workpiece limiting component are configurable, which can realize the rapid adaptation and adjustment of the carrier. It solves the problem of high cost and long cycle of carrier change caused by product change. It also significantly reduces the management complexity of the carrier, reduces the input of labor costs, effectively reduces the storage space occupation, and improves the economy and efficiency of the overall logistics operation.

[0029] 2. This utility model provides a logistics carrier for the entire production process of shell-shaped workpieces. By setting multiple robotic gripping blocks along one pair of edges of the logistics carrier, unmanned carrier handling operations are achieved on an automated production line, effectively avoiding the inefficiency and cost of manual handling. Furthermore, a unique identification code is set on the logistics carrier, which strictly corresponds to the workpiece information to be loaded onto the carrier within the automated management system, thereby ensuring that the automated production line can accurately allocate the workpieces to be loaded into the corresponding logistics carriers. Further, by limiting the height of the logistics carrier's frame, the loaded workpieces can be smoothly and stably transported and stacked, improving the flexibility and efficiency of the entire logistics process.

[0030] 3. This utility model provides a logistics carrier for the entire production process of shell-type workpieces, which adopts an innovative hollow structure design. This effectively solves the problem of insufficient compatibility with adaptable equipment in existing technologies and reduces the weight of the carrier itself. It ensures that the loaded workpieces can be cleaned without dead angles in six directions, greatly improving the cleaning effect. At the same time, this hollow design significantly reduces the overall weight of the logistics carrier, thus facilitating efficient and convenient handling operations using automated equipment and manual labor, further improving production efficiency and operational flexibility.

Detailed Implementation

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] like Figure 1 and Figure 2 As shown, a logistics carrier for the entire production process of shell workpieces includes an upper frame 1, a lower frame 2, multiple columns 3 connected and fixed to the corners of the upper and lower frames, four basic positioning plates 4, multiple bottom support ribs 11, a connecting base plate 17, and a workpiece limiting unit.

[0041] like Figure 2 , Figure 5 , Figure 6 and Figure 7 The workpiece limiting unit shown includes six L-shaped limiting blocks 18. These limiting blocks perform coarse positioning, effectively constraining the movement of the shell workpiece in four external directions, thereby simplifying the loading process of the shell workpiece. There is also a U-shaped limiting block 19 and two limiting posts 20, which together undertake the precision limiting task. By accurately positioning the shell workpiece in space, they ensure that the robot arm can perform gripping operations accurately. These limiting units are installed as follows: Figure 3 The upper surface of the connecting base plate 17 is shown, and it is fastened to other circular holes inside the connecting base plate 17 by mounting bolts. This combination design exhibits high flexibility and can adapt to up to 10 different types of housing workpieces, realizing the versatility of logistics vehicles for housing workpieces.

[0042] To ensure the installation accuracy of the workpiece limiting unit, such as Figure 1 As shown, four base positioning plates 4 are arranged at the four corners inside the lower frame 2; the mounting holes of the base positioning plates 4 and the bolt assembly holes 21 provided at the four corners of the connecting base plate 17 are connected by bolts to achieve stable assembly and positioning, while the base positioning plates 4 provide a support surface for the connecting base plate 17.

[0043] To strengthen the supporting role of the base positioning plate 4 on the connecting base plate 17, such as Figure 1 As shown, a U-shaped rib 12 is provided on the side of the lower frame 2 near the clearance groove 7. The two ends of the U-shaped rib 12 are connected to the lower frame 2 and the base positioning plate 4 respectively. Multiple parallel bottom support ribs 11 are provided in the lower frame 2. The U-shaped rib 12 and the bottom support ribs 11 provide auxiliary support for the connecting base plate 17.

[0044] To strengthen the connection between the top border 1 and the bottom border 2, such as Figure 1 As shown, W-shaped ribs 9 are provided on the four edges of the lower frame 2, and two straight vertical ribs 10 are provided on each of a pair of edges, both of which are connected to the upper frame 1.

[0045] To achieve unmanned logistics vehicle handling on automated production lines, such as Figure 1 and Figure 4 As shown, a guide plate 5 is provided on the inner side of each pair of edges of the lower frame 2, forming a flat surface at the bottom of the lower frame 2, allowing the logistics carrier to move smoothly along the roller conveyor; the light shield 6 and the guide plate 5 are integrally formed and connected to the column 3, ensuring that the logistics carrier can be accurately identified and detected by relevant equipment during automated transportation and positioning; between one pair of upper frame 1 and lower frame 2, there are robotic gripper blocks 14 distributed on both sides of the W-shaped rib, one side connected to the straight vertical rib 10, and the other side connected to the W-shaped rib 9. The upper side is connected to the upper frame 1, facilitating the robotic gripper's grasping of the logistics carrier. An identification code mounting plate 15 is located on one side of the robotic gripper block 14, between the upper frame 1, the straight rib 10, and the column 3. An identification code 16 is mounted on the mounting plate 15, and the two are connected by rivets. This identification code is unique and strictly corresponds to the workpiece information to be loaded onto the carrier within the automated management system, thus ensuring that the automated production line can accurately allocate the workpieces to be loaded into the corresponding logistics carriers. Furthermore, for large-structure shell workpieces, by limiting the height of the logistics carrier's frame, the robotic gripper can grasp the carrier from multiple angles, ensuring that the loaded workpieces can be smoothly and stably transported and stacked.

[0046] To allow multiple vehicles to be stacked together, saving storage space, such as Figure 1 As shown, one pair of edges of the lower frame 2 are recessed inward to form a relief groove 7; an inverted U-shaped structure 8 is connected to the outside of the relief groove 7 of the lower frame 2. The inverted U-shaped structure 8 is connected to the upper frame 1. The upper end of the inverted U-shaped structure 8 is higher than the upper frame 1, and the upper width of the inverted U-shaped structure 8 and the distance between the inverted U-shaped structures 8 are respectively matched with the upper width of the relief groove 7 and the distance between the two relief grooves 7.

[0047] To correctly identify and operate carriers in automated production lines or logistics processes, such as Figure 1 As shown, a square front and back identification plate 13 is connected to one side of the upper frame 1, and is connected to the W-shaped rib 9 and the upper frame 1.

[0048] like Figure 1As shown, the logistics carrier adopts a structure design with a fully hollowed-out bottom and all four sides to ensure that the workpiece can be cleaned from all angles, thus achieving compatibility and adaptability with various cleaning equipment throughout the entire production process.

[0049] like Figure 1 The components shown are welded together as a single piece. Figure 5 , Figure 6 , Figure 7 The component shown is integrally molded by high-pressure injection molding.
