Description

Technical Field

[0001] This utility model relates to automated production technology and automated production equipment, specifically, a CCS laser welding mechanism. Background Technology

[0002] CCS, or Battery Connector System, is a core component of battery packs in the rapidly developing new energy vehicle industry. Its production quality directly impacts the safety and stability of the battery system. Laser welding, with its advantages of high precision, small heat-affected zone, and high connection strength, has become a key process in CCS module assembly. Currently, mainstream CCS laser welding mechanisms in the industry generally adopt a single-product-specific integrated cover plate structure. This means that for a specific CCS model, a matching integrated positioning cover plate is designed to fix the product before laser welding.

[0003] However, this traditional integral cover plate laser welding mechanism has significant limitations in practical applications, making it difficult to meet the "diversified, flexible, and rapid changeover" production needs of modern manufacturing. Specific problems are as follows: 1) Poor product compatibility and high replacement costs: The entire cover plate is tied to a specific product model. When producing CCS products of different specifications (such as connectors with different numbers of cells or busbars of different sizes), a complete set of dedicated cover plates must be redesigned and manufactured. The newly manufactured cover plates require machining and precision calibration, with a single set typically costing several thousand yuan and a processing cycle of 3-5 days, significantly increasing production costs and waiting time. 2) High maintenance difficulty and low flexibility: The overall cover plate structure is complex, and after long-term use, problems such as wear of the positioning reference and deformation of the cover plate are prone to occur. Maintenance requires complete disassembly, repair or replacement, which is not only time-consuming (1-2 hours for a single maintenance), but may also cause positioning accuracy deviation due to reinstallation; at the same time, the positioning points and clamping force of the cover plate are fixed in design, and cannot be flexibly adjusted according to the subtle adjustment needs of the product (such as the offset of welding points, the adaptation of clamping force for different material parts), and has poor adaptability to product design changes; 3) Significant environmental impact during welding: CCS laser welding generates a large amount of welding fumes (containing metal oxides and volatile gases) and irritating odors. Traditional methods often lack dedicated fume collection devices or place them too far from the welding area, making effective fume removal difficult. Long-term accumulation of fumes adheres to the laser head and positioning reference surface, affecting welding accuracy and equipment lifespan. Simultaneously, the irritating odor diffuses into the workshop environment, potentially impacting operator health and failing to meet environmental protection requirements.

[0004] Therefore, it is necessary to provide a CCS laser welding mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a CCS laser welding mechanism that enables rapid model changeover, low maintenance costs, and good dust collection, thereby solving the pain points of traditional mechanisms and improving CCS production efficiency and quality.

[0006] The technical solution is as follows: A CCS laser welding mechanism includes a laser welder mounting plate, on which a laser welder is mounted, and a welding fume extraction module is provided corresponding to the laser welder. A quick-connect welding head is also provided below the laser welder mounting plate, and the quick-connect welding head is connected to the laser welder mounting plate by means of screws for detachable fixing or quick-connect bayonet for quick insertion and removal. The quick-connect welding head includes a head body, and a holding part is located below the head body; The laser welder mounting plate has connecting plates at both ends, which are connected to a flexible floating connection structure.

[0007] Furthermore, quick-connect welding heads include various head bodies of the same length but different widths.

[0008] Furthermore, the quick-connect welding head includes a head body of the same specification and a holding part with different lengths and / or different setting positions.

[0009] Furthermore, the welding fume extraction module includes two suction heads, which are symmetrically arranged on both sides of the laser welder. The two suction heads are connected to an external suction pipe and suction equipment.

[0010] Furthermore, the connecting plate is slidably connected to a linear slide rail on an elastic adjustment bracket via a sliding block.

[0011] Furthermore, the top of the connecting plate holds an elastic element.

[0012] Furthermore, the elastic element is a spring.

[0013] Compared with existing technologies, this invention enables rapid model changeover, low maintenance costs, and excellent dust collection, solving the pain points of traditional mechanisms and improving CCS production efficiency and quality. Attached Figure Description
