Description

[0001] LI-ION BATTERY POUCH TYPE CELLS CASSETTE BONDING UNIT

[0002] Technical Field:

[0003] This invention relates to a gluing unit for li-ion battery pouch type cells to cassette.

[0004] State of the Art:

[0005] Batteries are devices that allow electrical energy to be stored and used when needed.

[0006] Lithium-ion batteries, or li-ion batteries for short, are fastrecharging batteries. Li-ion batteries provide a significant amount of power for a long time for their size and weight.

[0007] In contrast, li-ion batteries have significantly lower carbon emissions and toxic values than other battery types.

[0008] Due to said features, li-ion batteries are used in many electronic devices, especially in tablets and cell phones.

[0009] Today, li-ion batteries are also used in hybrid vehicles and electric vehicles, of which use increases.

[0010] Li-ion batteries are currently classified into three types: cylinder type li-ion batteries, prism type li-ion batteries, and sachet type li-ion batteries.

[0011] Spraying an adhesive liquid is required in Li-Ion battery pouch type cells to connect the parts and keep the cells in place in the module. However, no structure exists that can integrate the adhesive liquid spraying process with automation systems.

[0012] The current applied adhesive liquid spraying process is carried out under the supervision of the operation staff. As a result, adhesive liquid cannot be applied evenly and consistently to all cells. In this case, a standard adhesive liquid application cannot be provided.

[0013] On the other hand, since the process is performed by operators, it is necessary to constantly keep the process and the stock of adhesive liquid under control. This not only increases the rate of errors in the process and, ultimately, the products, but it also reduces production efficiency and speed.

[0014] The Object of the Invention:

[0015] The invention aims to provide a uniform and homogeneous adhesive liquid spraying process for all battery cells, ensuring a uniform standard of adhesion by automatically performing the process.

[0016] Another object of the invention is to improve production efficiency and speed by lowering the error rate of both the process and the final products by allowing the process to be performed automatically.

[0025] Description of the Invention:

[0026] The structure of the inventive li-ion battery pouch type cell cassette gluing unit (1) comprises an adhesive spraying module (1.1) , which performs the process of spraying adhesive liquid evenly and homogeneously by using the signals from the system when the cell cassettes are positioned in the desired position; a Y-axis motion module (1.2) providing vertical movement of the gluing unit (1) and an X-axis motion module (1.3) providing horizontal movement of the gluing unit (1) .

[0027] The inventive li-ion battery pouch type cell cassette gluing unit (1) performs the process of spraying adhesive liquid by using the signals from the system when the cell cassettes placed on the fixture are positioned in the desired position.

[0028] In this process, the fixture is an assembly or production layout in which the cell bowls are placed within a certain layout and positioning.

[0029] The adhesive spraying stage of the adhesive spraying module (1.1) applies uniform and homogeneous amounts of adhesive liquid to ensure that the cell cassettes are securely attached to one another.

[0030] The inventive li-ion battery pouch type cell cassette gluing unit (1) may comprise more than one adhesive spraying module

[0031] (1.1) .

[0032] The Y-axis motion module (1.2) allows the gluing unit (1) to move vertically along the Y-axis.

[0033] The X-axis motion module (1.3) allows the gluing unit (1) to move horizontally along the X-axis.

[0034] The Y-axis motion module (1.2) and X-axis motion module (1.3) are servo systems.

[0035] After the gluing process is completed, the battery cells are placed on the cassettes, which allows the glued parts to be fixed in the desired position. Thus, it is ensured that the battery cell cases are attached and fixed.

[0036] Thanks to the inventive gluing unit (1) , each part is properly attached and remains in the desired position in the module. The even and homogeneous application of the adhesive liquid creates a strong bond between the parts, increasing the mechanical durability of the battery module while also helping to safely maintain electrical contact for the batteries.
