Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and particularly relates to a drying device for battery steel shells. Background Art

[0002] During the production process of battery steel shells, it is necessary to dry the electroplating solution and antirust oil on the surface of the battery steel shells. At present, air drying is adopted for the battery steel shells, and the drying efficiency is relatively low. Therefore, in some cases, the battery steel shells to be dried are placed in a drying chamber, and then hot air is introduced into the drying chamber to raise the temperature in the drying chamber to the corresponding drying temperature, while maintaining continuous ventilation in the drying chamber to improve production efficiency. However, since the battery steel shells in the drying chamber are stacked together, the liquid on the inner walls of some battery steel shells located in the inner layer is difficult to effectively remove, resulting in poor treatment effects and reduced treatment efficiency.

The battery steel shell can rotate around the limit columns, accelerating the liquid on the inner wall of the battery steel shell to be thrown out, improving the drying efficiency. At the same time, the limit top plate limits the battery steel shell to prevent the battery steel shell from detaching from the limit columns; meanwhile, hot air enters the ventilation cavity in the heat dissipation disc through the air inlet pipe, and then evenly flows to the battery steel shell on the limit chassis through the air outlet holes distributed on the upper end surface of the heat dissipation disc. Moreover, the hot air flow can enter the inner wall of the battery steel shell through the air blowing holes on the limit columns, which is beneficial to avoiding liquid residues on the inner walls of some battery steel shells. Place the battery steel shell to be dried into the blanking hole on the loading tray. The third spring pushes the limit block to press and position the battery steel shell in the blanking hole. During feeding, just align the limit posts on the limit chassis with the blanking holes on the loading tray. The driving motor drives the winding cylinder to rotate, causing all the limit blocks to move towards the positioning ring side simultaneously and the third spring to contract. After the limit blocks disengage from the battery steel shell, the battery steel shells in all the blanking holes enter the limit posts on the limit chassis correspondingly, thus loading the battery steel shells on multiple loading trays onto multiple limit chassis, which facilitates loading. A support boss can be provided at the bottom of the loading tray. After the support boss passes through the first relief hole on the limit chassis, it supports on the workbench, which facilitates aligning the limit posts on the limit chassis with the blanking holes on the loading tray during loading.
