Problems solved by technology
In the traditional method, after the welding of the modules is completed, the employees will check the firmness and reliability one by one. This method requires a lot of manpower, and the inspection standards cannot be unified due to the inconsistent methods of each person, and it is easy to damage the well-welded modules. point
It is easy to miss detection, misjudgment, and low efficiency
In addition, in the prior art, there are also visual detection technologies such as 2D detection or 3D. This method has high detection efficiency, but the visual detection is a non-contact detection, and there is no substantial contact with the detection object, so it cannot be expressed intuitively. Welding strength is prone to misjudgment and misjudgment

An embodiment of the invention provides a welding detection apparatus and a detection method, which are used for performing welding detection on a battery cell in a battery module. The welding detection device comprises a suction nozzle, a pipeline, a vacuum generator, a cylinder and a control apparatus. One end of the pipeline is connected with the suction nozzle, and the other end of the pipeline is connected with the vacuum generator. The cylinder is connected with the suction nozzle through a connecting arm, and the control apparatus is electrically connected with the vacuum generator andthe cylinder. The cylinder is used for moving up and down under the control of the control apparatus and driving the suction nozzle to move in a vertical direction through the connecting arm. The vacuum generator is used for generating a vacuum pressure under the control of the control apparatus. The suction nozzle is used for generating a suction force under the effect of the vacuum generator, soas to suck a welding tab on the battery cell to detect the welding strength of the welding tab. According to the welding detection scheme, the vacuum generator and the suction nozzle are fitted to generate the suction force, so as to adsorb the welding tab, thereby detecting the welding strength, the structure is simple, the automation degree is high, and the detection accuracy is high.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a welding detection device and a detection method. Background technique [0002] At present, laser welding and ultrasonic welding technology have been widely used in automobiles, electronics and other fields. In the field of new energy, there are more and more applications of laser welding, such as the welding of battery poles and pole pieces, the welding of manifolds and pole pieces, and so on. After using the laser to weld the battery core and pole piece, it is necessary to check the firmness and reliability of the laser welding point. In the traditional method, after the welding of the modules is completed, the employees will check the firmness and reliability one by one. This method requires a lot of manpower, and the inspection standards cannot be unified due to the inconsistent methods of each person, and it is easy to damage the well-welded modules. point. I...
