DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the structures of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] In the description of the present invention, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use, or are the orientation or position relationship commonly understood by those skilled in the art. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0048] Furthermore, the terms “first,” “second,” “third,” etc., are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0049] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0050] During the battery module assembly process, the batteries need to be placed in the battery pack shell before welding. To increase the energy level of the battery module, welding parts are used to connect the batteries in series or parallel. In actual production, high-energy fusion is generally used. The welding parts are placed on the battery welding surface. After the welding parts are pressed against the battery cell welding surface, high-energy laser is emitted to the welding parts surface, and high-temperature fusion welding is carried out to the battery welding surface.

[0051] Existing welding heads are typically copper indenters. The indenter is pressed against the welding surface, compacting it. Energy then flows through the indenter to weld the workpiece to the battery. Laser welding equipment welds battery modules at high temperatures and high energy levels. During the welding process, welding slag and ash continuously adhere to the inner wall of the laser welding head. Long-term accumulation can seriously affect weld quality.

[0052] The current method for cleaning welding heads typically involves workers manually cleaning the welding slag and ash from the inner wall of the welding head with a cotton swab at regular intervals. This method not only increases labor intensity but also reduces the degree of automation. Furthermore, this method can easily cause dropped welding slag and ash to enter the interior of the equipment, making it difficult to maintain 5S standards within the equipment.

[0053] Based on the above situation, the embodiments of this specification provide a welding head cleaning device and equipment, which can effectively alleviate the above technical problems.

[0059] When cleaning the welding head, the welding head is fixed to the cleaning brush 21, and the cleaning brush 21 is driven by the brush drive assembly 22 to clean the inner hole of the welding head. At the same time, the air supply pipe 31 is moved to the cleaning brush 21 to supply air, and the cleaned welding slag and welding ash are sucked away from the dust suction port through the dust suction pipe 11 to prevent the welding slag and welding ash from entering the interior of the equipment.

When cleaning the welding pressure head, an air supply device can be connected to the air inlet 341. The air sent out by the air supply device enters the interior of the air supply pipe 31 through the air inlet 341, and then flows out from the air outlet 311 set at the front end of the air supply pipe 31.

[0078] Optionally, the second fixing assembly 60 includes a backing plate 61, a second fixing horizontal plate 62 and a second fixing vertical plate 63;
