Description

Technical Field

[0001] The present invention relates to the technical field of power batteries, and in particular to an operating method of a recycling device for recycling scrapped power batteries. Background Art

[0002] Lithium-ion power battery is a new type of high-energy battery successfully developed in the 20th century. The negative electrode of this battery is made of materials such as graphite, and the positive electrode is made of materials such as lithium iron phosphate, lithium cobalt oxide, and lithium titanate. Due to its advantages such as high energy, high battery voltage, wide operating temperature range, and long storage life, it has been widely used in military and civilian small electrical appliances. At the same time, large-capacity lithium-ion batteries have been tried in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century.

[0003] The life cycle of a power battery includes production, use, scrapping, decomposition and reuse. After the power battery is scrapped, except for the decrease in chemical activity, the chemical composition inside the battery has not changed. It’s just that its charging and discharging performance does not meet the power requirements of the vehicle, but it can be used in places where the power requirements are lower than those of the car. Since the top of the power battery is sealed by laser welding when it leaves the factory, it is difficult to disassemble manually and the process is cumbersome. The disassembly is inefficient and the waste gas, waste liquid and dust generated during the processing will harm the health of the operator. In addition, most of the battery cells have been severely deformed during use, which will make it impossible or difficult to pull the core out of the shell. Summary of the invention

[0015] Compared with the prior art, the recycling device for scrapped power batteries in the present invention has the following advantages:

[0016] (1) The flip mechanism can drive the power battery to flip up and down. Specifically, the flip motor drives the flip plate and the power battery to rotate 180 degrees in the forward direction to reach an inverted state after being driven by the belt transmission system. Conversely, the flip motor drives the flip plate and the power battery to rotate 180 degrees in the reverse direction after being driven by the belt transmission system to return to the upright state. The contents of the power battery in the inverted state are easier to dump out.

[0017] (2) The deflection mechanism can drive the power battery to deflect left and right. Specifically, the deflection motor rotates forward 90 degrees and transmits through the deflection bar and the linkage bar, which drives the linkage plate and the power battery to rotate 90 degrees. Conversely, the deflection motor rotates reversely 90 degrees and transmits through the deflection bar and the linkage bar, which drives the linkage plate and the power battery to rotate 90 degrees. The power battery that can rotate by itself avoids the installation of cutting components on the left and right sides, simplifying the overall structure of the recovery device.

[0018] (3) The power battery can be temporarily fixed on the deflection mechanism through the clamping mechanism. Specifically, the power battery is clamped in the front-to-back direction by the clamping blocks on both sides, and then the piston rod of the clamping cylinder contracts and drives the lifting bar downward, thereby driving the clamping plates on both sides to complete the self-centering clamping of the power battery in the left-to-right direction. Conversely, the piston rod of the clamping cylinder extends and drives the lifting bar upward, thereby driving the clamping plates on both sides away from the power battery, that is, releasing the power battery.

[0019] (4) The shell of the power battery is cut in an annular shape by means of a cutting mechanism. Specifically, the piston rod close to the cylinder is contracted to drive the rodless cylinders on both sides close to the power battery, and then the rodless cylinder drives the rotating cutting blade to cut the front and rear sides of the power battery. Then, the piston rod close to the cylinder is extended to drive the rodless cylinders on both sides away from the power battery. After the power battery rotates 90 degrees, the above-mentioned cutting process is performed again, thereby achieving an annular cutting of the shell of the power battery.

The piston rod of the clamping cylinder (311) contracts and drives the lifting bar (312) downward, driving the clamping plates (307) on both sides to complete the self-centering clamping of the power battery (50) in the left-right direction; Step 2: The piston rod close to the cylinder (410) contracts to drive the rodless cylinders (404) on both sides close to the power battery (50), and the rodless cylinders (404) drive the rotating cutting blades (408) to cut the front and rear sides of the power battery (50), and the piston rod close to the cylinder (410) extends and drives the rodless cylinders (404) on both sides away from the power battery (50); Step 3: The deflection motor (207) rotates forward 90 degrees and after being transmitted by the deflection bar (20+) and the linkage bar (206), drives the linkage plate (205) and the power battery (50) to rotate 90 degrees; Step 4: The piston rod close to the cylinder (410) contracts and drives the rodless cylinders (404) on both sides to approach the power battery, the rodless cylinder (404) drives the rotating cutting blade (408) to cut the front and rear sides of the power battery (50), and the piston rod close to the cylinder (410) extends and drives the rodless cylinders (404) on both sides away from the power battery (50); Step 5: After being driven by the belt transmission system, the flip motor (106) drives the flip plate (102) and the power battery (50) to rotate 180 degrees in the forward direction to reach an inverted state; Step 6: The deflection motor (207) reverses 90 degrees and drives the deflection bar (209) and the linkage bar (206) to drive the linkage plate (205) and the power battery (50) to rotate 90 degrees, so as to quickly vibrate out the material inside the power battery (50) and convey it away through the conveyor belt below; Step 7: The piston rod of the clamping cylinder (311) extends and drives the lifting bar (312) downward, thereby driving the clamping plates (307) on both sides away from the shell of the power battery (50), and the shell of the power battery (50) falls to the conveyor belt below under its own gravity and is conveyed away; Step 8: After being driven by the belt transmission system, the flip motor (106) drives the flip plate (102) and the power battery (50) to rotate 180 degrees in the opposite direction to reach an upright state.

2. The operating method of a recycling device for scrapped power batteries according to claim 1, characterized in that: A corrosion-resistant friction pad (308) is pasted on the inner wall of the clamping plate (307).
