Detailed Implementation

[0024] Example 1, please refer to Figures 1 to 4This is a schematic diagram of a turnover pallet and conveyor production line for assembly line carriers provided by this utility model. The turnover pallet for assembly line carriers includes: a pallet body 10, and a carrier positioning structure 20 disposed on the pallet body 10. It is conceivable that this turnover pallet for assembly line carriers first fixes the parts with the carrier, and then positions the carrier and parts with the turnover pallet to achieve the overall conveying and turnover on the assembly line. This turnover pallet for assembly line carriers also includes other cooperating functional components and specific structures, such as assembly line components, robotic arm components, etc., which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0025] The pallet body 10 is typically rectangular, circular, or other conventional structures. In this embodiment, a rectangular shape is used as an example for detailed explanation. A carrier positioning step is provided on the pallet body 10 for positioning and installing the carrier and its clamping components.

[0026] Specifically, the carrier positioning structure 20 includes a recessed mounting groove 21 on the upper end of the pallet body 10. The mounting groove 21 serves as the overall installation space, and the carrier typically protrudes from the upper end of the mounting groove 21 after installation, facilitating automatic gripping and placement by the robotic arm. A recessed contour positioning groove 22 is provided at the bottom of the mounting groove 21, approximating the bottom structure of the carrier. The bottom of the carrier fits and is confined within the contour positioning groove 22, forming bottom positioning. A radially connected protruding positioning groove 23 is provided on one side of the mounting groove 21. Utilizing the radially protruding structure with the highest circumferential outer wall strength of the carrier, it can fit snugly into the protruding positioning groove 23, forming circumferential fixation of the carrier structure. A clearance notch 24 is provided at the edge of the contour positioning groove 22 near the inner wall of the mounting groove 21. The clearance notch 24 provides horizontal adjustment space for the carrier positioning and embedding in the mounting groove 21, reducing impacts between the carrier and the inner wall of the mounting groove 21 during installation, as well as the impact of external impacts on the pallet body 10 on the internal carrier. Furthermore, a limiting step 25 is formed between the inner wall of the mounting groove 21 and the contour positioning groove 22. The limiting step 25 is used to ensure the positioning effect of the contour positioning groove 22.

[0027] Ideally, the height of step 25 is limited to be greater than the bottom height of the contour groove, and the height of step 25 is limited to be less than the bottom height of the mounting groove 21. By setting different heights in the mounting groove 21, it is beneficial for the carrier and its parts to be guided into the contour positioning groove 22 in a layered manner. Ideally, the upper edge of the protrusion positioning groove 23 is provided with an guide slope 28, which provides a guiding effect for the radially protruding structure of the carrier to enter the protrusion positioning groove 23.

[0028] The main body 10 of this pallet includes a base and stacking trays. In this embodiment, the main body 10 of the pallet, which serves as the base, is a solid block structure made of metal. It is relatively heavy and has a flat bottom, which can stably ensure stability on the production line. The inner wall of the mounting groove 21 and the outer wall of the main body 10 have a main body partition 13. The main body partition 13 is a high-strength structure that is not easily deformed under stress, providing a structural foundation for the stacking of trays.

[0029] In this embodiment, the tray body 10, serving as the stacking tray, has a thin-shell structure and is typically made of plastic. The carrier and its components can be used individually when inserted, and can be stacked when empty. The tray body 10 is lightweight, does not affect the overall center of gravity when stacked, has deformation capability, and is easier to load and unload. Due to its thin-shell structure, the recessed mounting groove 21 forms a reverse-protruding structural protrusion 14 at the bottom of the tray body 10. A buffer gap 15 is provided between the outer periphery of the tray body 10 and the structural protrusion 14, forming a partition so that impacts to the outer periphery of the tray body 10 will not affect the carrier and its components directly reaching the mounting groove 21. Optimally, a radially protruding annular edge 17 is provided at the peripheral edge of the bottom of the tray body 10, increasing the support of the thin-shell structure of the tray body 10.

[0030] A tapered surface 11 is provided on the circumferential outer wall of the pallet body 10, meaning the pallet body 10 has a structure that is narrower at the top and wider at the bottom, which facilitates vertical stacking. Stacking positioning steps 12 are provided at intervals on the circumferential outer wall of the pallet body 10. In this embodiment, the stacking positioning steps 12 are located at the corners of the pallet body 10. During the stacking of multiple pallets, the stacking positioning steps 12 can limit the maximum stacking depth, ensuring the positioning accuracy of the stacked pallets and preventing unremoved carriers from flowing into the next process. Anti-adsorption grooves 16 are provided at intervals on the circumferential outer wall of the pallet body 10. The anti-adsorption grooves 16 of the lower pallet body 10 are always partially exposed, avoiding the problem of negative pressure adsorption caused by circumferential closure during stacking, which would make separation difficult.

[0031] A recessed positioning blind hole 26 is provided on the stacking positioning step 12, and a corresponding positioning protrusion 27 is formed at the bottom of the tray body 10. When stacking trays, the positioning protrusion 27 of the upper tray body 10 is inserted into the positioning blind hole 26 below, further improving the positioning accuracy.

[0032] Example 2: This utility model also provides a conveyor production line having a turnover pallet for the assembly line carrier as described above. Except for the turnover pallet for the assembly line carrier, all other components are existing technology or commercially available parts.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
