Abstract
Description
Technical Field
[0001] The utility model relates to a laser dust removal technology, in particular to a module pole laser cleaning and dust removal structure. Background Art
[0002] A power battery module is a combination of several battery cells connected in series and parallel. The battery pole is a crucial component of the battery cell, used to electrically connect the cells. Multiple batteries are electrically connected through the poles, often requiring welding of metal connecting wires to the poles. Because the surfaces of the battery cell poles are rarely cleaned, they can become contaminated with dust, oil, and other contaminants. Direct welding can result in poor welds. Therefore, laser cleaning of the poles is a crucial step in the battery module manufacturing process. The cleanliness of the pole surface after laser cleaning significantly impacts the welding results in the next welding process step.
[0003] In existing technologies, the laser cleaning solution for battery pack modules uses a non-metallic plate with through-holes corresponding to the positions of the poles. The laser passes through the through-holes to clean the poles. Simultaneously, an open dust collection structure is used above the non-metallic plate to remove dust during the cleaning process. Due to the large size of power batteries, a relatively large non-metallic plate is required to cover the entire battery module.
[0004] However, the strength of non-metallic plates is generally low. When the area of the non-metallic plate is too large, the non-metallic plate is prone to deformation. Similarly, the through-hole for passing the laser will also be deformed. In this way, it is difficult to ensure that the laser beam remains coaxial with the pole being cleaned after passing through the through-hole. This deviation in coaxiality will lead to cleaning deviations during the laser cleaning process, and it is easy for some positions to not be cleaned, affecting the cleanliness of the pole. In the prior art, the thickness of the non-metallic plate is often increased to increase its strength. However, thickening the non-metallic plate increases the cost. At the same time, due to the increase in thickness and the fact that the dust suction port is located above the non-metallic plate, the dust suction port is far away from the pole being cleaned by the laser, resulting in the smoke and welding slag generated after welding cannot be sucked away by the dust removal.

[0026] The present invention will be further described below through specific implementation methods in conjunction with the accompanying drawings. DETAILED DESCRIPTION
[0027] See also Figures 1 and 2 The utility model discloses a module pole laser cleaning and dust removal structure, comprising a fixing frame 1, a laser generator 2, a laser galvanometer 3 and a dust removal cover 4;
[0028] The laser generator is fixedly mounted on a first side of the top surface of the fixing frame, and the dust cover is mounted on a second side of the fixing frame and passes through the fixing frame; the laser galvanometer is located on the top surface of the fixing frame and between the laser generator and the dust cover;
[0029] The dust hood includes a dust removal pipeline and a non-metallic bottom plate 41; the internal cavity of the non-metallic bottom plate serves as a dust collection chamber, and the dust collection chamber is connected to the dust removal pipeline;
[0030] The dust removal pipeline passes through the fixed frame; the main dust suction port 42 on the dust removal pipeline for connecting to the external dust suction pipeline is located above the fixed frame; the non-metallic bottom plate is located below the fixed frame, and a laser dust removal port 411 is provided on the non-metallic bottom plate 41, and the laser dust removal port is connected to the dust removal pipeline through the dust suction chamber.
[0031] The utility model provides a modular pole laser cleaning and dust removal structure. When the pole laser cleaning is performed, the mobile fixed frame drives each component to move above the battery pole. The laser dust removal port of the non-metallic bottom plate corresponds to the pole position, and the laser passes through the laser dust removal port to clean the pole. During the cleaning process, the welding slag smoke generated is sucked through the laser dust removal port, passes through the dust suction chamber and enters the dust removal pipeline and is sucked away. The use of a non-metallic bottom plate with relatively high insulation performance can prevent the pole from short-circuiting, provide safety protection, and ensure the safety and reliability of insulation. The utility model provides a modular pole laser cleaning and dust removal structure, which can be moved at any time according to the use position. This mobile dust removal structure can effectively avoid the inconvenience of movement and cost waste caused by large-sized non-metallic plates.
[0032] In a specific implementation, the fixing frame is a square frame surrounded by four rectangular plates.
[0033] The four rectangular plates are connected end to end in sequence to form a hollow square frame.
[0034] During specific implementation, a first mounting plate 11 is provided on a first side of the top surface of the fixing frame 1 , and the laser generator 2 is fixedly mounted on the upper surface of the first mounting plate 11 .
[0035] In a specific implementation, a second mounting plate 12 is provided in the fixing frame. The second mounting plate and the first mounting plate are perpendicular to each other and are adjacent to each other. The laser galvanometer 3 is fixedly mounted on the second mounting plate 12 .
[0036] The second mounting plate is perpendicular to the first mounting plate and is L-shaped. The first mounting plate is a horizontal plate, and the laser generator is located on the top surface of the first mounting plate. The second mounting plate is a vertical plate, and the laser galvanometer is fixed to the side of the second mounting plate away from the second mounting plate.
[0037] During specific implementation, the dust removal pipeline includes a main dust suction port 42, a first dust removal branch 43 and a second dust removal branch 44; the main dust suction port is used to connect to an external dust suction pipeline; the upper ends of the first dust removal branch and the second dust removal branch are both connected to the main dust suction port, and the lower ends of the first dust removal branch and the second dust removal branch are both connected to the dust collection chamber.
[0038] Two dust removal branches, located on either side of the dust collection chamber, deliver dust drawn into the chamber to the main suction port, completing dust absorption and transfer. The use of one dust collection chamber and two dust removal branches ensures uniform and stable airflow distribution. The two dust removal branches converge at the main suction port, ensuring the stability of the entire dust collection pipeline.
[0039] During specific implementation, the first dust removal branch and the second dust removal branch are divided into an upper section and a lower section; the lower section is a vertical tube perpendicular to the surface of the non-metallic bottom plate, and the upper section is an inclined tube, which is obliquely leaned against the side wall of the main dust suction port.
[0040] The first dust removal branch and the second dust removal branch both adopt a bent pipe structure. By changing the bending angles of the two dust removal branches, the wind speed of the air flow in the dust removal branches can be adjusted to improve the dust removal effect.
[0041] In a specific implementation, a fixing bracket 5 is provided on the second side of the fixing frame, and the first dust removal branch and the second dust removal branch pass through the fixing bracket and are fixed to the fixing frame through the fixing bracket.
[0042] During specific implementation, the first dust removal branch and the second dust removal branch are connected to the non-metallic bottom plate 41 via reinforcing ribs 45 .
[0043] The reinforcement ribs ensure the connection reliability between the two dust removal branches and the non-metallic bottom plate, while improving the strength and stability of the dust removal branches and the non-metallic bottom plate.
[0044] During specific implementation, a plurality of laser dust removal ports 411 are provided on the non-metallic bottom plate 41 , and the laser dust removal ports are communicated with the dust collection chamber.
[0045] Laser light passes through the laser dust removal port to clean the corresponding pole. The laser dust removal port also serves as a shielding and dust removal suction port. The laser dust removal port has a small gap. This small gap can ensure dust removal air speed while protecting the area outside the pole. Furthermore, multiple laser dust removal ports and multiple laser galvanometers are used, with each laser dust removal port cleaning a pole, allowing more poles to be cleaned at once.
[0046] During specific implementation, a fixing plate 13 is provided on the outer side surface of the second side of the fixing frame 1 , and a visual component 6 is provided on the fixing plate 13 .
[0047] The vision component is a CCD camera, used to detect the module tray's mark point (reference point) for precise positioning. The mark point forms a coordinate system for the poles, guiding the laser to the corresponding poles for cleaning. Please explain the purpose of the vision component.
[0048] This utility model features a modular pole laser cleaning and dust removal structure. When welding poles, the non-metallic bottom plate beneath the dust hood is adjusted according to the pole's position, while the laser focal length of the laser galvanometer is also adjusted. This adjustment allows the dust hood to be positioned close to the pole. Because the dust hood is in close proximity to the pole, the laser dust removal port effectively draws smoke and welding slag into the dust chamber during welding. The dust chamber then transports the smoke and welding slag to the main dust intake via two dust removal branches, completing the dust removal process.
[0049] At the same time, after cleaning a group of poles, the dust removal cover moves synchronously with the fixed frame, and the laser dust removal port moves to the next group of poles, ensuring that the laser dust removal port is coaxial with the poles and aligned with the poles to effectively prevent the laser from cleaning outside the poles.
