Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil preparation technology, and specifically relates to a heat treatment system for aluminum foil rolls, which is suitable for large-scale furnace applications. Background Technology

[0002] Battery aluminum foil is an important material widely used in lithium-ion batteries and other batteries. It is mainly used to connect the positive and negative electrodes of the battery to provide current conduction and electrolyte isolation.

[0003] Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness and improve machinability; reduce residual stress, stabilize dimensions, and reduce the tendency for deformation and cracking; refine grain size, adjust microstructure, and eliminate structural defects.

[0004] Currently, aluminum foil production typically involves annealing in an annealing furnace, and sometimes tempering. Existing aluminum foil roll heat treatment systems include a furnace body, a horizontally pushing loading / unloading trolley, a material rack tray, and furnace tracks at the bottom of the furnace body. The furnace body is arranged longitudinally. The horizontally pushing loading / unloading trolley includes a main carriage, running tracks on the main carriage that engage with the furnace body tracks, a tray hook trolley sliding on the running tracks, and two rotatable tray hooks at both ends of the tray hook trolley. The aluminum foil roll is placed on the material rack tray. The horizontally pushing loading / unloading trolley faces the furnace body and can move longitudinally. Its running tracks connect with the furnace body tracks (the horizontally pushing loading / unloading trolley moves towards the furnace body). The tray hooks can hook onto the corresponding ends of the material rack tray to drag the tray. The material rack tray can slide on the furnace body tracks and the running tracks. The horizontally pushing loading / unloading trolley allows the material rack tray to be transferred between the main carriage and the furnace body.

[0005] For example, patent application number CN202410616532.1 discloses an annealing furnace for aluminum foil production, including a furnace body, a trolley, and two blocking blocks. The furnace body is equipped with an air circulation mechanism and a heating mechanism. The air circulation mechanism circulates air between the furnace body and the heating mechanism, while the heating mechanism heats the air. One side of the furnace body has an opening with two openable furnace doors. A threshold is located at the bottom of the opening, and the upper surface of the threshold has two notches. Two parallel tracks pass through the two notches from the outside of the furnace body and into the furnace body. The trolley can move along the two tracks to enter and exit the furnace body. The bottom of the trolley is higher than the upper surface of the threshold. The upper surface of the threshold also has two grooves, located on one side of the two notches and connected to them. A pressure plate is fixedly installed on one side wall of each blocking block. The two blocking blocks are detachably installed in the two notches, and the two pressure plates are used for… The two blocks are placed in two grooves; each groove has a blind hole at the bottom, and two movable columns are movably installed in the two blind holes. Two compression springs are installed in the two blind holes, with one end of each spring abutting the bottom surface of the two blind holes and the other end abutting the lower end of each movable column. When the two blocks are removed from the two notches, both springs are in an extended state, and the upper ends of the two movable columns extend beyond the upper surface of the threshold. At this time, the two movable columns can block the two furnace doors so that they cannot be closed, and the bottom of the trolley is higher than the upper ends of the two movable columns. When the two blocks are placed in the two notches, two pressure plates are placed in the two grooves, and the two pressure plates press down on the two movable columns. The upper surfaces of the two pressure plates and the upper surfaces of the two blocks are flush with the upper surface of the threshold.

[0006] For example, patent application number CN202022166008.9 discloses a novel annealing furnace, including a furnace body and a furnace door. The furnace door is located at the front end of the furnace body, and a material rack tray is located on the inner side of the furnace body. An electrical control box is located on the right side of the furnace body at the front position. A traveling trolley is located at the front end of the furnace door. Traveling rails are located on the upper end of the traveling trolley at both the front and rear sides. Pulleys are located at the upper ends of the traveling rails, and a tray hook trolley is connected to the outer side of the pulleys. The tray hook trolley... The upper end is equipped with audible and visual alarm lights at the four corners. The front and rear ends of the pallet hook trolley are fitted with stainless steel hooks at the left and right sides. The upper end of the running trolley is equipped with a railing at the front right side. A fixed operating platform is provided inside the railing. The front end of the running trolley is equipped with a step at the middle right side. The material rack pallet is connected to a flat-push automatic material trolley. The upper end of the flat-push automatic material trolley is equipped with a ladder at the rear left side. A stainless steel material rack is provided at the upper end of the flat-push automatic material trolley.

[0007] Existing technologies are mainly applicable to single furnace bodies, with flat-push feeding and discharging trolleys that can be fixed or move freely; for multiple furnace bodies, multiple flat-push feeding and discharging trolleys need to be set up, which not only requires a large investment but also occupies a lot of space.
