The invention relates to the field of battery production, and discloses a seal nail welding system. The system comprises a rotating disc, a seal nail positioning mechanism, a welding mechanism and a detection mechanism; multiple battery clamps are arranged on the rotating disc, the multiple battery clamps are evenly arranged around the center of the rotating disc, the seal nail positioning mechanism, the welding mechanism and the detection mechanism are sequentially arranged on the periphery of the rotating disc in a surrounding manner, the seal nail positioning mechanism is used for placing asealing nail on the assembling position of the seal nail on the battery, the detection mechanism is used for detecting whether welding of the seal nail is qualified or not, the welding mechanism comprises a first drive component, a welding head and a protection device, the connecting end of the welding head is rotatably arranged at the action end of the first drive component, the connecting end of the protection device is connected with the laser emitting-out end of the welding head and is used for blowing protection gas to the welding position, and the protection device is coaxial with the welding head. The seal nail welding system can accurately weld the seal nail on the assembling position on the battery, and the seal nail assembling yield is improved.
Description
technical field [0001] The invention relates to the field of battery production, in particular to a sealing nail welding system. Background technique [0002] Laser welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. [0003] In the prior art, when welding the battery, first, the sealing nail is pressed into the injection port of the electrolyte by manual setting; then, the sealing nail is welded by laser welding, that is, the laser is perpendicular to the battery cover Welding; after the welding is completed, the battery leaves the factory. The existing battery sealing nail welding method has problems such as inconvenient operation, inaccurate sealing nail welding, low efficiency, etc., resulting in the problem of poor quality of the factory batter...
