Description

Technical Field

[0001] The invention relates to the field of lithium battery production, and in particular to a pole piece drying device for lithium battery production. Background Art

[0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on the transfer of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is embedded and deintercalated back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops all use lithium-ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium elements as electrodes and are the representative of modern high-performance batteries. However, real lithium batteries are rarely used in daily electronic products due to their high risk. Compared with traditional batteries, lithium-ion batteries have excellent performance advantages such as high operating voltage and good cycle life; these excellent performances are largely derived from the fact that the system in which lithium-ion batteries work belongs to a non-aqueous electrochemical system. Therefore, if you want to manufacture lithium-ion batteries with excellent performance, you must do a good job of drying the batteries, especially the electrodes; Existing drying devices generally use electric heating devices to bake directly, which can easily cause local overheating, causing the electrode to be overheated and damaged. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a lithium battery production electrode drying device, which has the advantages of solving the problems raised in the above background technology.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A lithium battery production pole piece drying device comprises a base, a drying box is fixedly connected to the top of the base, a moving groove is provided at the top of the drying box, a moving block is slidably matched in the moving groove, a pushing assembly is provided in the moving groove for driving the moving block to move horizontally left and right, a fan is provided at the bottom of the moving block, a support plate is fixedly connected to the bottom of the drying box below the fan, a drying assembly is provided on the support plate, the drying assembly comprises an annular groove provided on the upper surface of the support plate, an annular tube is matched and connected in the annular groove, the upper part of the annular tube extends to the outside of the annular groove, and the annular tube is provided with a push assembly to drive the moving block to move horizontally left and right. An annular heat conducting plate is fixedly connected above the extended end of the tube, and a plurality of electrode sheets are placed on the upper surface of the annular heat conducting plate. A water pump is connected to one end of the annular tube, and a water outlet pipe is connected to the other end of the annular tube. Both the water pump and the water outlet pipe extend to the outside of the drying box. A water pump is connected to the extended end of the water pump, and a water receiving pipe is connected to the side of the water pump away from the water pump, and a water storage tank is connected between the water receiving pipe and the water outlet pipe. The water storage tank is fixedly connected to the outer wall of the base, and a power connection is provided on the outer wall of the water storage tank. The power connection is electrically connected to an electric heating pipe, and the electric heating pipe is placed in the water storage tank.

[0005] By adopting the above technical scheme, when in use, the operator places the electrode sheets on the annular heat conduction plate in sequence, and then the operator starts the water pump to pump the water in the annular tube into the water tank through the water connecting pipe. The external civil electricity can be connected to the electric heating tube by connecting the power supply, so that the electric heating tube can be powered, so that the temperature of the electric heating tube rises, and the water in the water tank can be further heated. The heated water in the water tank will flow back to the annular tube through the water outlet, so that the temperature in the drying box and the temperature of the annular heat conduction plate can be increased, and the electrode sheets can be evenly heated and dried. During the drying process, the operator starts the push assembly, cooperates to move the moving block and the fan at the bottom of the moving block horizontally left and right, and turns on the fan to speed up the air flow rate in the drying box, thereby improving the drying efficiency. Further configuration: the pushing assembly includes fixed seats arranged on both sides of the moving groove, a screw rod is rotatably connected between the fixed seats, the moving block is matched and connected to the outside of the screw rod, one end of the screw rod extends to the outside of the drying box, and the extended end of the screw rod is connected to a servo motor through a coupling.

[0006] By adopting the above technical solution, during operation, the operator turns on the servo motor to drive the screw to rotate. At this time, the moving block on the screw and the fan at the bottom of the moving block move back and forth left and right, so as to blow air to various areas of the drying box, thereby accelerating the air flow rate in the drying box and improving the efficiency of the drying operation.

[0007] It is further configured that: a lifting cylinder is fixedly connected to the bottom of the moving block, a lifting plate is fixedly connected to the bottom of the output end of the lifting cylinder, and the lifting plate is fixedly connected to the top of the fan at a side away from the lifting cylinder.

[0008] By adopting the above technical solution, when the fan is performing the blowing operation, the operator can open the lifting cylinder and cooperate with the lifting plate to lift the fan up and down to a suitable height, thereby cooperating with the fan to blow and dry the surface of the electrode sheet, thereby indirectly improving the drying operation efficiency.

[0009] It is further configured that a door is hinged on the outside of the drying box, a plurality of heat dissipation holes are opened on the door, and dust screens are arranged in the plurality of heat dissipation holes.

[0010] By adopting the above technical solution, the hot air generated in the drying box can be ventilated and dissipated through the multiple heat dissipation holes on the box door, and the dust shielding net can also play a dust shielding role.

[0011] Further configuration: universal wheels are arranged around the bottom of the drying box.

[0012] By adopting the above technical solution, the setting of the universal wheel makes it easy for the operator to move the entire equipment, which is flexible and convenient.

[0013] In summary, the present invention has the following beneficial effects: When the present invention is used, the operator places the electrode sheets on the annular heat conduction plate in sequence, and then the operator starts the water pump to pump the water in the annular tube into the water tank through the water connecting pipe. The external civil electricity can be connected to the electric heating tube by connecting the power supply, so that the electric heating tube can be powered, so that the temperature of the electric heating tube rises, and the water in the water tank can be further heated. The heated water in the water tank will flow back to the annular tube through the water outlet, so that the temperature in the drying box and the temperature of the annular heat conduction plate can be increased, and the electrode sheets can be evenly heated and dried. During the drying process, the operator starts the pushing assembly, cooperates to move the moving block and the fan at the bottom of the moving block horizontally left and right, and turns on the fan to speed up the air flow rate in the drying box, thereby improving the drying efficiency.
