[0002] The production and manufacturing of lithium-ion batteries is a process that is closely linked to each process step. Generally speaking, the production of lithium batteries includes the manufacturing process of pole pieces, the battery assembly process, and the final filling, sealing, formation, and aging processes. Aging is to charge and discharge the manufactured lithium-ion batteries with a small current. After the lithium battery is manufactured, the battery needs to be charged and discharged with a small current.

Since the batteries are closely arranged, the heat conduction is slow and uneven, resulting in uneven heating of individual batteries and inconsistent diffusion of the internal electrolyte, which affects the electrical performance of the batteries. In addition, the interior of the current aging chamber is usually a one-way transmission belt assembly structure, which will cause the battery carrier to be heated differently at different positions of the motor during internal operation, and the residence time in the aging chamber is short, and a high number of battery carriers aged at a single time cannot be maintained.

[0006] As a preferred embodiment, the uniform heating mechanism includes an auxiliary motor, a rotating disk, an engaging frame, two groups of force-bearing slide rails, a transmission belt assembly, three groups of convex teeth and an air guide tube. The rotating disk is fixedly connected to the output shaft of the auxiliary motor, and the two groups of force-bearing slide rails are respectively fixedly connected to the left and right ends of the bottom of the engaging frame. One side of the rotating disk is movably connected to the force-bearing slide rail through a toggle pin. The three groups of convex teeth are all engaged with the top of the engaging frame, and the three groups of convex teeth are distributed in equidistant straight lines about the engaging frame. The air guide tube is fixedly connected to one side of the convex teeth.

[0007] As a preferred embodiment, the auxiliary motor is fixedly connected to the aging chamber via a fixed frame, the engaging frame is slidably connected to the aging chamber via a slide frame, the air guide tube is located at the top end of the aging chamber, and the end of the air guide tube away from the convex teeth is movably connected to the air supply pipe.

[0008] As a preferred embodiment, the two groups of force-bearing slide rails correspond to two groups of rotating disks respectively, and the two groups of rotating disks are connected by a transmission belt assembly, one end of the transmission belt assembly is movably connected to the output shaft of the auxiliary motor through a pulley, and an air port is opened at the bottom of the air guide cylinder, and the air port is aligned with the straight transmission belt and the arc transmission belt.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-6 As shown, the present invention provides a technical solution: a cylindrical rechargeable battery aging and aging device, comprising an aging chamber 1, an end cover 2 and a carrier bracket 6, the end cover 2 is fixedly connected to the top of the aging chamber 1, the top of the end cover 2 is fixedly connected to a thermal engine 3, three groups of straight conveyor belts 4 are arranged inside the aging chamber 1, an arc conveyor belt 5 is arranged at one end of adjacent straight conveyor belts 4, and the straight conveyor belts 4 and the arc conveyor belts 5 are movably connected to the aging chamber 1 through a fixed frame, the carrier bracket 6 is located at the top of the straight conveyor belt 4, a double mechanism 7 is arranged on one side of the arc conveyor belt 5, a uniform heating mechanism 8 is fixedly connected to one side of the aging chamber 1, and an air supply duct 9 is fixedly connected to the other side of the aging chamber 1 away from the uniform heating mechanism 8.

[0025] In this embodiment, the carrier bracket 6 is first placed on the surface of the linear conveyor belt 4, and then the double-link mechanism 7 between the two adjacent groups of linear conveyor belts 4 in the aging chamber 1 is driven. After the double-link mechanism 7 is driven, it can drive the linear conveyor belt 4 and the arc-shaped conveyor belt 5 to transmit, and the movement speeds of the linear conveyor belt 4 and the arc-shaped conveyor belt 5 can be kept consistent under the control of the double-link mechanism 7, so that the carrier bracket 6 is driven by the linear conveyor belt 4 and the arc-shaped conveyor belt 5 to enter the belt aging chamber 1. At this time, the thermal engine 3 on the top of the end cover 2 is driven to provide heat to the inside of the aging chamber 1, thereby achieving better aging operation, and the three groups of linear conveyors The belt 4 cooperates with two groups of arc-shaped conveyor belts 5 to present an S-shaped movement trajectory inside the aging chamber 1, which effectively increases the time that the carrier bracket 6 stays inside the aging chamber 1, and can meet the operation of simultaneous aging of multiple groups of carrier brackets 6, effectively improving the aging efficiency. During the aging process, the uniform heating mechanism 8 on one side of the aging chamber 1 is driven. Under the air supply operation of the air supply pipe 9, the uniform heating mechanism 8 reciprocates and blows the surface of the straight conveyor belt 4 and the arc-shaped conveyor belt 5 inside the aging chamber 1, thereby achieving uniform heat inside the aging chamber 1, effectively improving the aging quality, and ensuring that the batteries at various positions on the surface of the carrier bracket 6 are heated uniformly.

[0026] like Figure 3 and Figure 5 As shown, the heat uniforming mechanism 8 includes an auxiliary motor 801, a rotating disk 802, an engagement frame 803, two groups of force-bearing slide rails 804, a transmission belt assembly 805, three groups of convex teeth 806 and an air guide tube 807. The rotating disk 802 is fixedly connected to the output shaft of the auxiliary motor 801, the two groups of force-bearing slide rails 804 are respectively fixedly connected to the left and right ends of the bottom of the engagement frame 803, one side of the rotating disk 802 is movably connected to the force-bearing slide rail 804 through a toggle pin, the three groups of convex teeth 806 are all engaged with the top of the engagement frame 803, and the three groups of convex teeth 806 are equidistantly distributed in straight lines with respect to the engagement frame 803, and the air guide tube 807 is fixedly connected to one side of the convex teeth 806. The auxiliary motor 801 is fixedly connected to the aging chamber 1 through a fixed frame, the engaging frame 803 is slidably connected to the aging chamber 1 through a sliding frame, the air guide tube 807 is located at the top of the aging chamber 1, and one end of the air guide tube 807 away from the convex teeth 806 is movably connected to the air supply pipe 9. The two groups of force-bearing slide rails 804 correspond to the two groups of rotating disks 802 respectively, and the two groups of rotating disks 802 are connected through a transmission belt assembly 805, one end of the transmission belt assembly 805 is movably connected to the output shaft of the auxiliary motor 801 through a pulley, and an air port is opened at the bottom of the air guide tube 807, and the air port is aligned with the linear transmission belt 4 and the arc transmission belt 5.

[0027] In this embodiment, first, the auxiliary motor 801 is driven to drive the rotating disk 802 to rotate, and the force-bearing slide rail 804 at the bottom of the meshing frame 803 is affected by the toggle pin on the surface of the rotating disk 802, driving the meshing frame 803 to produce a reciprocating motion effect on one side of the aging chamber 1. At the same time, under the transmission effect of the transmission belt assembly 805, the two groups of force-bearing slide rails 804 work simultaneously, which effectively improves the stability of the movement of the meshing frame 803. During the reciprocating motion of the meshing frame 803, the three groups of convex teeth 806 on the top can be realized. Reciprocating rotation, thereby driving the rotation effect of the air guide tube 807 inside the aging chamber 1, so that the air inlet at the bottom of the air guide tube 807 can effectively align with various positions on the surface of the linear conveyor belt 4 and the arc conveyor belt 5. At this time, the air supply duct 9 again introduces gas into the air guide tube 807, and the air pressure directly and evenly brings heat to the batteries on the surface of the carrier bracket 6, thereby effectively improving the aging effect of the batteries at various positions.

[0028] like Figure 4 and Figure 6 As shown, the double-link mechanism 7 includes a main motor 701, a linkage rod 702, two sets of main bevel gears 703, two sets of secondary bevel gears 704 and a linkage roller 705. One end of the linkage rod 702 is fixedly connected to the output shaft of the main motor 701. Both sets of main bevel gears 703 are fixedly connected to the linkage rod 702. Two sets of secondary bevel gears 704 are respectively meshed with the left and right ends of the main bevel gears 703, and the two sets of secondary bevel gears 704 are oppositely distributed to each other. The linkage roller 705 is fixedly connected to the secondary bevel gears 704. The main motor 701 is fixedly connected to the fixed frame on the surface of the linear transmission belt 4. The linkage roller 705 is fitted with one end of the linear transmission belt 4 and the arc-shaped transmission belt 5, and the linear transmission belt 4 and the arc-shaped transmission belt 5 are transmission-connected to the main motor 701 through the linkage roller 705. One end of the linkage rod 702 away from the main motor 701 is movably connected to a fixing frame on the surface of the arc-shaped conveyor belt 5 through a shaft sleeve, and both ends of the arc-shaped conveyor belt 5 are aligned with the linear conveyor belt 4 .

[0029] After the main motor 701 is driven, the connecting rod 702 is driven to rotate. Two groups of main bevel teeth 703 are fixed on the surface of the connecting rod 702. The two groups of main bevel teeth 703 correspond to the transmission of the two groups of auxiliary bevel teeth 704 respectively, and the two groups of auxiliary bevel teeth 704 are distributed opposite to each other. In this way, after the main bevel teeth 703 rotate, the two groups of auxiliary bevel teeth 704 can be driven to rotate in the wrong direction, thereby driving the connecting roller 705 to rotate respectively. The connecting roller 705 is directly in contact with one end of the linear conveyor belt 4 and the arc conveyor belt 5. In this way, the rotation effect of the connecting roller 705 can effectively drive the linear conveyor belt 4 and the arc conveyor belt 5 to transmit, thereby realizing the movement effect of the top carrier bracket 6, and the three groups of linear conveyor belts 4 cooperate with the two groups of arc conveyor belts 5 to form an S-shaped motion trajectory inside the aging chamber 1, which effectively increases the number of carrier brackets 6 for single aging, effectively extends the aging distance, and improves the aging efficiency.

[0030] Working principle: first, the carrier bracket 6 is placed on the surface of the linear conveyor belt 4, and then the double-link mechanism 7 between the two adjacent groups of linear conveyor belts 4 in the aging chamber 1 is driven. After the main motor 701 is driven, it drives the connecting rod 702 to rotate, and the main bevel gear 703 drives the main bevel gear 703 to rotate, so that the two groups of secondary bevel gears 704 are forced to rotate in the wrong direction, thereby driving the connecting roller 705 to rotate, and different connecting rollers 705 are respectively fitted with one end of the linear conveyor belt 4 and the arc conveyor belt 5, thereby driving the linear conveyor belt 4 and the arc conveyor belt 5 to rotate at the same speed, thereby driving the carrier bracket 6 to move inside the aging chamber 1, and an S-shaped motion trajectory is formed between the three groups of linear conveyor belts 4 and the two groups of arc conveyor belts 5 inside the aging chamber 1, which effectively increases the number of carrier brackets 6 for single aging, and extends the aging distance, effectively improving the aging efficiency, and the thermal engine 3 on the top of the end cover 2 is driven to provide a normal aging environment inside the aging chamber 1. During the aging process, the auxiliary motor 801 in the uniform heating mechanism 8 on one side of the aging chamber 1 is driven, and the auxiliary motor 801 drives the rotating disk 802 to rotate. The rotating disk 802 drives the force-bearing slide rail 804 at the bottom of the meshing frame 803 through the toggle pin, and the transmission belt assembly 805 realizes the transmission between the two sets of rotating disks 802, so that the reciprocating lateral movement effect of the meshing frame 803 on one side of the aging chamber 1 can be effectively realized. During the reciprocating motion of the meshing frame 803, the convex teeth 806 engaged at the top can be realized to reciprocate, and the convex teeth 806 drive the air guide tube 807 to rotate at the top inside the aging chamber 1, so that the air outlet at the bottom of the air guide tube 807 is aligned with various positions on the surface of the linear conveyor belt 4 and the arc conveyor belt 5, and one end of the air guide tube 807 is directly connected to the air supply pipe 9, so that the gas is blown to the carrier bracket 6 at various positions, so that the heat at various points inside the aging chamber 1 is maintained constant, effectively improving the aging effect.
