A single battery unit of a lead-acid battery includes a positive plate, a negative plate and sulfuric acid to form a charge-discharge unit, and a separator is arranged between the positive plate and the negative plate to avoid short circuit. The specific energy of the lead-acid battery is small. To achieve a larger electric capacity, the volume and weight of the lead-acid battery are often set to be larger, so as to provide a longer-lasting power supply. During the installation of heavy lead-acid batteries, manual installation of the electrode plate group requires a huge labor cost; at the same time, the labor efficiency is low, the installation consistency is poor, and the product yield is affected.

In some production workshops, automated assembly equipment is used to improve the efficiency of installation. The positive plates, negative plates and separators are respectively sent to the installation place through the conveyor line for assembly, and assembled into a plate group and then installed as a whole to the shell of the lead battery. body. During the installation process, the transport is carried out by grasping, hoisting and other operations by a robotic arm, such as a slot-in device for lead-acid battery pole plates recorded in the patent document CN111987367B. During the hoisting process, the dislocation and deformation of the pole plate group is prone to occur when it is turned over, which affects the installation effect and the quality of the product; at the same time, the current conveyor line needs to erect and tighten the positive plates, negative plates and separators when transporting them. For transportation, as disclosed in the patent application document CN114050300A, an automatic assembly device for lead-acid battery plates of electric vehicles needs to be erected, which cannot improve the efficiency of transportation.

Therefore, there is still room for improvement in the pole plate installation technology used in the production of the existing lead-acid batteries. The pole plate installation process not only has the problem of low efficiency, but also has the problem of dislocation and deformation of components caused by installation and transportation, which reduces the installation accuracy and quality. In addition, in the process of installing heavy plates and lead-acid batteries, the existing technology is difficult to implement smoothly.
