The invention relates to an integrated welding shooting structure, and a device and a method for detecting automatic welding of a cell. According to the welding shooting structure, functional devices with two different characters, i.e., laser welding and image shooting, are integrated through the way that an illumination light and a laser sharing share one light path. The welding shooting structure comprises a pedestal, a shooting component, a laser input light path component and a sharing light path component, wherein the shooting component comprises an industrial camera; the laser input light path component comprises a collimating tube and a water-cooling module; the sharing light path component comprises a welding lens; a shooting lens is arranged on the industrial camera; the collimating tube, the industrial camera and the welding lens are respectively connected onto the pedestal; the water-cooling module is positioned on the pedestal; the welding lens and the shooting lens are arranged face to face; and a reflecting surface and a coated reflecting lens component which are parallel to each other are arranged in the pedestal, and a 45-degree angle is formed between the bottom side of the pedestal and the coated reflecting lens component. Due to the fact that welding laser and shooting illumination share one light path, the structure is simplified, image acquisition for detection can be immediately finished after welding is finished, space resource is saved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to an automatic laser welding detection device for a power battery battery cell, more specifically an integrated welding shooting structure and an automatic welding detection device and method for a battery cell. Background technique [0002] With the adjustment of the national industrial policy and the intensive introduction of new energy vehicle support policies, the new energy vehicle market has shown explosive growth. The power battery is the core of the industry. The development of the new energy vehicle market has caused power battery companies to expand production one after another. Market competition white hot. In order to continuously meet the requirements of higher production efficiency and quality control, enhance the market competitive advantage of products, and increase market share, it has become an inevitable choice for power battery manufacturers to carry out technological transformation of the existing power batte...
