[0034] The following is based on the attached Figure 1 To the attached Figure 3 The utility model introduces a battery casing dust removal device.

[0035] like Figure 1 、 Figure 2 As shown, in this embodiment, the battery housing dust removal device mainly includes a blowing member 1 and a dust removal base 2. The blowing member 1 has an air inlet at the bottom and an air outlet at the top. The blowing member 1 can penetrate into the interior of the housing assembly 5, thereby blowing air to clean the interior of the housing assembly 5. The dust removal base 2 is used to support the blowing member 1 and the housing assembly 5. The dust removal base 2 is provided with an air intake 211 and an air hole 212. The air intake 211 is used to draw air from the interior of the housing assembly 5, and the air hole 212 is used to input air into the air inlet of the blowing member 1.

[0036] When in use, the open end of the shell assembly 5 is directed toward the dust removal base 2, and then the shell assembly 5 is placed on the dust removal base 2, and the blowing member 1 is extended into the interior of the shell assembly 5 through the opening (such as Figure 2 Then, air is blown into the blowing member 1 through the blowing hole 212, and the gas inside the shell assembly 5 is sucked through the suction port 211, so that a circulating airflow can be formed inside the shell assembly 5 (as shown). Figure 3 The airflow can carry away metal debris, dust and other non-metallic foreign matter, and discharge them out of the housing assembly 5 and the battery housing dust removal device through the air intake 211, thereby achieving dust removal and cleaning of the interior of the housing assembly 5.

[0037] Through the battery shell dust removal device, the interior of the shell component 5 can be conveniently and thoroughly blown clean, and by absorbing the air inside the shell component 5, a circulating airflow is formed inside the shell component 5, thereby quickly and thoroughly cleaning and separating the metal debris, dust and other non-metallic foreign matter inside the shell component 5, ensuring the cleanliness of the assembly process and avoiding abnormal phenomena such as battery short circuit and performance degradation.

[0038] Preferably, in this embodiment, a first limiting groove 213 is provided on the top surface of the dust removal base 2, an air intake 211 and an air blowing hole 212 are provided on the bottom surface of the first limiting groove 213, and the blowing member 1 is placed or fixedly disposed in the first limiting groove 213. The bottom end of the housing assembly 5 can be inserted between the side wall of the first limiting groove 213 and the outer wall of the blowing member 1 to limit and fix the housing assembly 5 in a direction parallel to the dust removal base 2, preventing the housing assembly 5 from moving under the action of airflow, thereby facilitating cleaning work.

[0039] It should be noted that in the present invention, there is no requirement for the specific shape of the shell assembly 5. For example, taking a common cylindrical battery as an example, its shell assembly 5 includes a cylindrical battery shell, and in this case, the first limiting groove 213 can be set as a circular groove. For a square battery, its shell assembly 5 includes a square battery shell, and in this case, the first limiting groove 213 can be set as a corresponding square groove. Therefore, the specific shape of the first limiting groove 213 is not limited in the present invention, as long as it can limit and fix the shell assembly 5 in a direction parallel to the dust removal base 2.

[0040] Optionally, in this embodiment, the cross-sectional areas of the blowing member 1 are arranged from large to small along the direction from the bottom end of the shell assembly 5 to the top end of the shell assembly 5. For example, referring to Figure 3 As shown, the blowing member 1 adopts a conical structure, thereby forming a larger space inside the shell assembly 5, facilitating the flow of airflow and achieving a better cleaning effect.

[0041] Preferably, to achieve a better air cleaning effect, the blow piece 1 adopts a conical structure, thereby forming a larger space for air flow inside the cylindrical battery housing or the prismatic battery housing. Furthermore, the blow piece 1 is provided with at least two air outlet holes, and the blow piece 1 is provided with air outlet holes on the top and side surfaces, so that a large area of ​​the inner surface of the housing assembly 5 can be directly blown, further improving the air cleaning effect and ensuring that no metal debris, dust and other non-metallic foreign matter remain.

[0042] Optionally, the bottom of the blowing piece 1 and the side wall of the first limiting groove 213 can clamp and fix the shell assembly 5, thereby further improving the stability of the shell assembly 5 during air blowing cleaning. At the same time, a ventilation groove 12 is provided on the side of the blowing piece 1, and the ventilation groove 12 extends in a direction perpendicular to the dust removal base 2. The bottom end of the ventilation groove 12 is connected to the air intake 211, thereby avoiding the blowing piece 1 from blocking the air intake 211 when clamping and fixing, so that the air flow can carry metal debris, dust and other non-metallic foreign matter and enter the air intake 211 through the ventilation groove 12. For example, in this embodiment, Figure 1 As shown, the blowing member 1 adopts a conical structure, and a plurality of ventilation grooves 12 are arranged at intervals on the bottom of the side surface.

[0043] Furthermore, if Figure 1 、 Figure 3 As shown, the battery housing dust removal device also includes a protective cover 3 and an upper cover 4. The protective cover 3 is open at both ends. One end of the protective cover 3 is used to abut the dust removal base 2, and the other end of the protective cover 3 is used to fix the upper cover 4. The dust removal base 2, the protective cover 3 and the upper cover 4 can define a dust removal space to accommodate the housing assembly 5 and the blowing member 1. By forming a dust removal space, it is possible to further reduce the adhesion of metal debris, dust and other non-metallic foreign matter to the outside of the housing assembly 5 during air blowing cleaning. It can also prevent metal debris, dust and other non-metallic foreign matter from further entering the interior of the housing assembly 5 during the assembly process, thereby ensuring the cleanliness of the assembly environment.

[0044] like Figure 1 As shown, the top surface of the dust removal base 2 is provided with a second limiting groove 214, into which the bottom end of the protective cover 3 can be inserted to limit and fix the protective cover 3 in a direction parallel to the dust removal base 2. The first limiting groove 213 is arranged inside the second limiting groove 214 at intervals, so that a space is formed between the protective cover 3 and the housing assembly 5 for the operator or the robot to reach in, thereby further facilitating air cleaning.

[0045] Preferably, if Figure 3 As shown, in this embodiment, the bottom surface of the upper cover 4 is provided with an abutting portion 41, which is used to abut the housing assembly 5 to press the housing assembly 5 against the dust removal base 2. The upper cover 4 and the protective cover 3 can be fixed by means of threaded connection, snap connection, etc., and the protective cover 3 can be inserted and fixed in the second limiting groove 214 by means of interference fit, bonding, etc., so that the upper cover 4 can press the housing assembly 5 against the dust removal base 2.

[0046] Alternatively, as Figure 3As shown, in this embodiment, the dust removal base 2 includes an air suction base 21 and an air blowing base 22, and the air blowing member 1, the air suction base 21 and the air blowing base 22 are connected from top to bottom. Among them, the air suction base 21 is provided with the above-mentioned first limiting groove 213, the second limiting groove 214, the air blowing hole 212 and the air suction port 211, and the air blowing base 22 is provided with a air blowing channel 221. One end of the air blowing channel 221 is connected to the air blowing device, and the other end can be connected to one end of the air blowing hole 212, so that the gas is blown into the air blowing member 1 connected to the other end of the air blowing hole 212. The air suction port 211 adopts an annular groove or a square groove corresponding to the shape of the shell component 5, and an air suction channel 215 is provided in the air suction base 21. One end of the air suction channel 215 is connected to the air suction device, and the other end is connected to the air suction port 211, so that the interior of the shell component 5 is evenly sucked through the air suction port 211.

[0047] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
