Description

Technical Field

[0001] This utility model relates to an auxiliary positioning device for lithium battery tabs, belonging to the field of lithium battery core processing technology. Background Technology

[0002] With the continuous growth of global demand for new energy, the battery industry, especially the production of lithium-ion batteries, has become a core component of the modern energy industry. Battery performance and safety are closely related to every step of its manufacturing process, particularly the processing of battery cores, where precision requirements are extremely stringent. Core processing equipment, as a core component in this process, plays a crucial role in improving battery production efficiency, reducing costs, and enhancing product quality.

[0003] Due to the characteristics of foil materials, copper foil and aluminum foil have low strength in their natural state and are prone to deformation. This results in poor consistency of the tab's condition during the core transportation and processing, low processing efficiency, and potential safety hazards in the produced batteries. Current technology involves placing a non-metallic flexible tube under the tab to assist in its positioning. However, because the tab moves rapidly on the flexible tube and causes friction, it is difficult to ensure that the tab is not damaged. Consequently, current technology cannot eliminate the waste generated when the core flows to the next process on the conveyor line. Utility Model Content

[0024] 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.

[0025] This utility model provides a lithium battery tab auxiliary positioning device, such as... Figures 1-3 As shown, the positioning device includes:

[0026] The machine base 1 has a guide positioning block assembly on its upper part. The guide positioning block assembly includes a guide positioning block 2 and a first air pipe connector 3 that is bolted to the end of the guide positioning block 2. The first air pipe connector 3 is connected to a compressed air source by a quick connector or other means.

[0027] The connecting rod assembly is disposed between the machine base 1 and the guide positioning block 2, and serves as a support;

[0028] The positioning device also includes an air blowing assembly, which is located on the machine base 1 to the left of the guide positioning block assembly. The position of the air blowing assembly is adjusted according to the different size specifications of the pole core 11.

[0029] As a further description of this embodiment, the air blowing assembly includes a strong magnetic base 4 fixed on the machine base 1 by strong magnetism, a bamboo tube 5 is provided above the strong magnetic base 4, and an air nozzle 6 is connected to the upper end of the bamboo tube 5.

[0030] As a further description of this embodiment, the strong magnetic base 4 is provided with a second air pipe connector 7 on its side wall.

[0031] As a further description of this embodiment, the connecting rod assembly includes a connecting rod 8 and fixing blocks 9 installed at the upper and lower ends of the connecting rod 8. The fixing blocks 9 at the upper and lower ends of the connecting rod 8 are respectively fixed to the guide positioning block 2 and the machine base 1 by bolts.

[0032] As a further description of this embodiment, the guide positioning block 2 is made of resin and is hollow inside. Its upper surface is provided with a plurality of air holes 10, and the plurality of air holes 10 are connected to the hollow inside.

[0033] As a preferred technical solution in this embodiment, the connecting rod 8 is made of aluminum alloy.

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

[0035] Step 1: First, fix the device of this utility model on the workbench and place it on both sides of the conveying system. The second air pipe connector 7 of the air blowing component and the first air pipe connector 3 on the right side of the guide positioning block 2 are both connected to compressed air.

[0036] Step 2: Place the pole core 11 above the air blowing assembly, adjust the bamboo tube 5 to the target direction, and adjust the compressed air pressure so that the pole tab 12 of the pole core 11 reaches the target state.

[0037] Step 3: Place the pole core 11 above the guide positioning block 2, adjust the compressed air pressure so that the pole tab 12 of the pole core 11 reaches the target state. After the adjustment is completed, remove the pole core for debugging.

[0038] Working principle: When the electrode core 11 is transported to the production line, the electrode tab 12 first passes through the air blowing assembly. The naturally drooping electrode tab is transformed from a drooping state to the target state by the compressed air released by the air blowing assembly. Simultaneously, the conveying system carries the electrode core 11 to the right and smoothly moves it above the guide positioning block 2. The electrode tab 12 is still able to maintain the target state by the compressed air in the air hole 10 of the guide positioning block 2. It is then transported by the conveying system to various processes on the production line for processing until all processing of the electrode core 11 is completed.
