Description

Technical Field

[0001] The invention relates to the technical field of battery processing equipment, and in particular to an all-in-one ultrasonic welding machine for positive and negative electrodes of a battery. Background Art

[0002] Ultrasonic welding is a process that uses high-frequency vibration waves to transfer energy, causing the surfaces of two objects to be welded to rub against each other under pressure and form a fusion between the molecular layers. During the process, the vibration acts on the material to be welded, causing high-speed friction between the two parts of the material, thereby causing the temperature to rise due to friction; when the temperature reaches the melting point of the material, the material interface will melt rapidly and cool and take shape under a certain pressure, forming a certain welding effect. The welding effect is stable, energy-saving, and does not require a heat dissipation and smoke dispersion structure. It has been widely used in the field of battery processing; the existing welding devices for the positive and negative electrodes of batteries can basically meet the daily use effects, but there are still certain shortcomings. First, the existing welding equipment for the positive and negative electrodes of batteries needs to manually replace the welding joints according to the actual situation during the processing of different batches of products, which increases the labor intensity of the staff; second, the existing welding equipment for the positive and negative electrodes of batteries needs to provide pressure during welding to ensure the welding quality, but the structure of the welding part is simple, and it is impossible to detect the deviation of the product during the pressure application process.
