Description

Technical Field

[0001] This utility model relates to a power battery sorting tray size inspection tooling, which belongs to the field of power battery manufacturing technology. Background Technology

[0002] In the production process of power batteries, the sorting tray, as a core load-bearing component, undertakes the functions of transferring, processing and positioning, and temporary storage of power battery cells. Its dimensional accuracy directly determines the safety and stability of the cell transfer process. Among them, the slot width of the sorting tray is a critical control dimension: if the slot width exceeds the tolerance (too large a width can easily cause the cells to shake and collide during transfer, while too small a width can easily cause the cells to jam and the casing to be scratched), it will directly cause damage to the cell casing. In severe cases, it may induce electrolyte leakage, thermal runaway, or even fire and other safety accidents, posing a significant risk to the production process and product quality.

[0003] Currently, the industry typically measures the width of card slots manually using handheld vernier calipers, slot by slot. This method has two major problems: first, it is extremely inefficient, requiring a large amount of manpower and failing to meet the inspection needs of mass production scenarios; second, it has significant measurement deviations, with results easily influenced by human error, making it difficult to guarantee consistent inspection accuracy and potentially leading to the influx of defective pallets. Therefore, the industry needs a more efficient and accurate solution for measuring the dimensions of sorting pallets. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a power battery sorting tray size inspection fixture that can more efficiently and accurately measure the size of sorting trays. It aims to improve the accuracy and efficiency of sorting tray size inspection and is suitable for batch inspection scenarios of different models of sorting tray slot width dimensions during power battery production.

[0005] This utility model discloses a tooling for inspecting the dimensions of a power battery sorting tray, characterized in that the tooling comprises:

[0006] Tooling body 1;

[0007] A plurality of upper comb teeth 2 are distributed on the upper side of the tooling body 1;

[0008] A plurality of lower comb teeth 3 are distributed on the lower side of the tooling body 1;

[0009] Tooling handle 4 is installed in the middle of the tooling body 1.

[0010] Furthermore, the tooling body 1 is provided with a plurality of positioning holes 5.

[0011] Furthermore, the tooling body 1, the several upper comb teeth 2, and the several lower comb teeth 3 are all made of high-hardness stainless steel.

[0012] Furthermore, the tips of several of the upper comb teeth 2 are rounded.

[0013] Furthermore, the tips of several of the lower comb teeth 3 are all rounded.

[0014] Furthermore, the spacing between the upper comb teeth 2 is slightly larger than the spacing between the lower comb teeth 3.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model tooling can quickly detect and accurately determine the width of the sorting tray slot. The operation process is simple and convenient, and no complicated debugging steps are required.

[0017] 2. Compared with traditional testing methods, this utility model has a significant cost advantage. By applying this tooling, the dimensional accuracy of the sorting tray can be effectively controlled, providing a reliable guarantee for the stability and product quality of the subsequent power battery production process.

[0023] The following is a specific embodiment of this utility model with reference to the accompanying drawings, and the structure of this utility model is described in detail. It should be noted that the scope of application of this utility model is not limited to the following embodiment; all similar structures based on this utility model are within the scope of application of this utility model.

[0024] This utility model provides a tooling for inspecting the dimensions of a power battery sorting tray, such as... Figures 1-2 As shown, the tooling includes:

[0025] Tooling body 1;

[0026] A plurality of upper comb teeth 2 are distributed on the upper side of the tooling body 1;

[0027] A plurality of lower comb teeth 3 are distributed on the lower side of the tooling body 1;

[0028] Tooling handle 4 is installed in the middle of the tooling body 1 to facilitate workers to pick up the tool for work.

[0029] As a further description of this embodiment, the tooling body 1 is provided with a plurality of positioning holes 5 for positioning and connection with the sorting tray 6.

[0030] As a further description of this embodiment, the tooling body 1, the plurality of upper comb teeth 2 and the plurality of lower comb teeth 3 are all made of high-hardness stainless steel, which can effectively ensure the long-term accuracy of the tooling.

[0031] As a further description of this embodiment, the tips of several of the upper comb teeth 2 are rounded, which can effectively avoid scratching the inner wall of the slot of the sorting tray 6.

[0032] As a further description of this embodiment, the tips of several of the lower comb teeth 3 are all rounded, which can effectively avoid scratching the inner wall of the slot of the sorting tray 6.

[0033] As a further description of this embodiment, the spacing between the upper comb teeth 2 is slightly larger than the spacing between the lower comb teeth 3.

[0034] The working principle of this utility model is as follows:

[0035] like Figure 3 As shown, the operator uses the tool handle 4 to move the inspection tool to the sorting tray 6 to be inspected, aligns the positioning hole 5 with the positioning post of the sorting tray 6, and inserts the positioning pin to complete the precise alignment; then, several lower comb teeth 3 are aligned with the slots of the sorting tray 6. If several lower comb teeth 3 can be smoothly inserted into the slots without obvious looseness, it means that the width of the slot is not less than the lower limit value; then, several upper comb teeth 2 are aligned with the same slot. If several upper comb teeth 2 cannot be inserted into the slots, it means that the width of the slot is not greater than the upper limit value; if both of the above conditions are met, it can be determined that the width of the slot of the sorting tray 6 is qualified, otherwise it is unqualified. The number and size of the upper comb teeth 2 and lower comb teeth 3 of the inspection tool of this utility model are produced according to the number and size of the slots of different sorting trays 6.
