The present invention relates to the field of mobile power production equipment and provides an automatic bonding device, comprising a base and an automatic pressing device, an automatic glue dispensing
machine and a
welding part mechanical arm arranged on the base, wherein the automatic pressing device is used for pressing battery core components, that is, battery cores and circuit board components welded to each other, the automatic glue dispensing
machine is used for adhering the battery core components pressed by the automatic pressing device to a shell, and the
welding part mechanical arm is used for transferring the battery core components on the automatic pressing device to a shell carried by a shell sliding device; the structure integrates the automatic pressing device, the automatic glue dispensing
machine and the
welding part mechanical arm into one to realize automatic pressing of battery core and circuit board components and automatic glue dispensing of the shell, so that the welded parts meet the flatness requirements and the battery core components and the shell are automatically bonded, and the operation process does not require manpower, and the degree of
automation and work efficiency are high.
