Description
Technical Field
The utility model belongs to the technical field of lead acid battery, concretely relates to battery wall welding strength testing arrangement.
Background
In the manufacturing process of the lead-acid storage battery, the pole groups of the storage battery are connected in series by welding the biased tabs by adopting a through-wall welding process basically, so that the rated voltage of the storage battery is ensured. The wall-through welding process is that the polarized lugs of two groups of poles are extruded through welding holes reserved in the wall of the storage battery and then are welded together under the action of ohmic heat of current. In order to control the quality of the storage battery product, the through-wall welding spot is usually detected by a resistance method. The resistance method is a method in which a certain direct current is applied to both sides of a welding spot after the completion of wall-piercing welding, the welding quality is judged by the voltage across the welding spot, and when the voltage is higher than a limit value, the welding quality of the wall-piercing welding is considered to be unqualified. Since the resistance method is tested according to the ohm's law principle, the quality defect of the through-wall welding cold welding of the storage battery cannot be found. The cold welding is characterized in that when the through-wall welding is carried out on the storage battery, because the contact area of the two bus bars after being extruded is large, the welding area is small, the resistance of a welding point is small, but the strength is low, the desoldering is easy to occur in the subsequent use process, and the phenomenon that the whole storage battery is scrapped is caused. Therefore, it is necessary to develop a device for testing the welding strength of the through-wall welding.
