[0036] The material withdrawal tube 95 is disposed obliquely, and the obliquely disposed material withdrawal tube 95 is used to facilitate the sliding of the power battery 7 .

[0037] The puncture mechanism includes a transmission arm 101, which is connected to the bottom of the end of the push column 93 away from the discharge bin 1 by bolts, and a sliding groove is provided at the end of the sliding arm close to the discharge bin 1.

The top end of the first crankshaft 102 is slidably connected to the sliding groove of the transmission arm 101, and a sliding frame 104 is slidably connected to the bottom of the discharge bin 1, and the sliding frame 104 is close to the preparation bin 91.

[0038] The puncture needle of the puncture device 106 is made of tungsten carbide, and the tungsten carbide puncture needle of the puncture device 106 is used to better puncture the power battery 7.

[0039] A circulation pump 12 is also included. The circulation pump 12 is connected to one side of the discharge chamber 1 by bolts. The liquid inlet and liquid outlet of the circulation pump 12 are both connected to the inside of the discharge chamber 1. The circulation pump 12 is used to increase the fluidity of the conductive liquid in the discharge chamber 1.

[0040] A guide bar 13 is also included. The guide bar 13 is connected to the material withdrawal tube 95 by bolts. The guide bar 13 is used to guide the power battery 7 to tilt downward into the material withdrawal tube 95 .

[0041] At first, the U-shaped bar 87 presses against a group of sliding bars 82 at the highest point through the roller 88, so that the tension spring 85 is compressed, so that a kind of clip 83 at the highest point is in an expanded state through the guide bar 84, and the drain valve 2 is in a closed state. First, the operator adds conductive liquid to the discharge bin 1, and then puts a number of power batteries 7 into the preparation bin 91, and at the same time connects the subsequent processing equipment with the return pipe 95. Then the operator controls the output shaft of the servo motor 3 to drive the wheel chain to rotate sixty degrees. The rotation of the sprocket 4 sixty degrees will drive the support seat 6 to rotate through the chain 5. After the support seat 6 at the original highest point rotates, the U-shaped bar 87 no longer presses against the sliding bar 82 at the original highest point through the roller 88, and the tension spring 85 at the original highest point is reset, so that the original highest point The slide bar 82 drives the clip 83 at the original highest position to return to its original position through the guide bar 84. When the clip 83 at the original highest position returns to its original position, it will first rotate half a circle through the guide bar 84, and then approach the power battery 7 and contact the power battery 7 placed on the support seat 6 at the original highest position. The tension spring 85 at the original highest position applies pressure to the power battery 7 at the original highest position through the slide bar 82 and the clip 83, so that the clip 83 at the original highest position clamps the power battery 7 at the original highest position, and at the same time, the other support seat 6 moves to the highest position. When the other support seat 6 moves to the highest position, the U-shaped bar 87 will squeeze the slide bar 82 at the current highest position to slide outward through the roller 88, and the tension spring 85 at the current highest position will be stretched. At the same time, the slide bar 82 will drive the clip 83 to pass through the guide bar 84 to After sliding outward for a certain distance, it rotates downward half a circle to be in an expanded state. After the servo motor 3 drives the sprocket 4 to rotate multiple times, the power battery 7 will follow the chain 5 through the support seat 6 to enter the conductive liquid. The power battery 7 immersed in the conductive liquid will cause a short circuit, and then the power battery 7 will release the remaining power. Then the operator controls the telescopic rod of the electric push rod 92 to drive the pushing column 93 to move toward the direction close to the discharge bin 1, so that the pushing column 93 pushes the power battery 7 from the preparation bin 91 into the support seat 6 at the top. If there is a discharged power battery 7 on the support seat 6, the pushing column 93 will push the discharged power battery 7 to the guide bar 13 through the power battery 7 pushed out from the preparation bin 91, and the guide bar 13 will guide the discharged power battery 7 to The power battery 7 after discharge is completed will enter the obliquely arranged return tube 95 and enter the next processing equipment through the return tube 95. After the push column 93 replaces the power battery 7, the servo motor 3 continues to drive the chain 5 to rotate through the sprocket 4, and repeats this process. The push column 93 replaces the power battery 7 on the support seat 6 in turn. At the same time, the clamp 83 clamps the power battery 7 after it leaves the highest position. Then, the power battery 7 follows the support seat 6 and is immersed in the conductive liquid in turn for discharge. In this way, the clamp 83 at the top is unfolded by the U-shaped bar 87 to replace the discharged power battery 7 with the power battery 7 waiting to be discharged, thereby continuously discharging multiple power batteries 7, thereby improving the discharge speed of the power battery 7.Thereby improving the discharge efficiency of the waste power battery 7; while the pushing column 93 pushes the material, it will drive the first crankshaft 102 to rotate through the transmission arm 101, and the rotation of the first crankshaft 102 will squeeze the sliding frame 104 to move in the direction close to the drain valve 2, and the movement of the sliding frame 104 will squeeze the piercer 106 upward through the oblique groove of the sliding frame 104, and the upward movement of the piercer 106 will penetrate into the power battery 7 through the piercing needle made of tungsten carbide of the piercer 106. In this way, while the pushing column 93 pushes the material, the piercing needle of the piercer 106 penetrates into the interior of the power battery 7, and then punctures the power battery 7, so that the discharge device can perform short-circuit discharge by destroying the internal structure of the power battery 7, thereby enhancing the discharge of the waste power battery 7. Electric effect; after the pushing column 93 completes the pushing, the telescopic rod of the electric push rod 92 drives the pushing column 93 to reset, and the reset of the pushing column 93 drives the first crankshaft 102 to reset through the transmission arm 101, and the reset of the first crankshaft 102 drives the puncture device 106 to reset through the sliding frame 104, and the puncture device 106 resets so that the puncture needle of the puncture device 106 is pulled out from the power battery 7. During the short-circuit discharge process of the power battery 7 after the puncture, it is easy to cause the local temperature in the conductive liquid to rise. At this time, the operator turns on the circulation pump 12, and the circulation pump 12 sucks the conductive liquid in the discharge chamber 1 through the liquid inlet, and then re-injects the conductive liquid into the discharge chamber 1 through the liquid outlet, thereby increasing the fluidity of the liquid inside the discharge chamber 1, and thereby making the temperature of the conductive liquid warmer.

[0042] Embodiment 2: Based on embodiment 1, Figure 1-Figure 13 As shown, it also includes an anti-rotation mechanism, which is arranged on the support beam 105. The anti-rotation mechanism is used to prevent the power battery 7 from rotating when the puncture device 106 punctures the power battery 7. The anti-rotation mechanism includes a lifting frame 111, and two lifting frames 111 are slidably connected to both sides of the support beam 105. The two lifting frames 111 are symmetrically arranged, and sliding grooves are provided at both ends of the two lifting frames 111. Pressure springs 114 are connected between the two lifting frames 111 and the support beam 105, respectively. The top two ends of the support beam 105 are rotatably connected to two second curved The two second crankshafts 112 are symmetrically arranged, and the two ends of the two second crankshafts 112 are respectively slidably connected to the sliding grooves at the two ends of the two lifting frames 111. Each of the second crankshafts 112 is connected to two rubber wheels 113 through a key groove. The lifting frame 111 is used to drive the rubber wheels 113 to rotate through the second crankshaft 112. The two rubber wheels 113 on the same second crankshaft 112 form a group, and the two rubber wheels 113 in the same group are symmetrically arranged. The two groups of rubber wheels 113 are symmetrically arranged, and the rubber wheels 113 are used to squeeze the power battery 7.

[0043] The rubber wheel 113 is provided with a plurality of grooves, and the grooves of the rubber wheel 113 are used to increase the resistance of the power battery 7 to rotation.

[0044] Initially, the puncture device 106 presses against the lifting frame 111, so that the pressure spring 114 is compressed. When the puncture device 106 moves upward for puncture, the puncture device 106 no longer presses against the lifting frame 111, and the pressure spring 114 resets to make the lifting frame 111 move upward. The upward movement of the lifting frame 111 will squeeze the second crankshaft 112 through the sliding groove to rotate upward. The upward rotation of the second crankshaft 112 will drive the rubber wheel 113 to rotate upward. The upward rotation of the rubber wheel 113 will squeeze the power battery 7, and at the same time, the groove on the rubber wheel 113 will increase the resistance to the rotation of the power battery 7. Force, in this way, before puncturing the power battery 7, the power battery 7 is squeezed by four rubber wheels 113 with a plurality of grooves, so that the cylindrical power battery 7 is not easy to rotate, and the cylindrical power battery 7 is more stable, thereby further enhancing the discharge effect of the power battery 7; after the power battery 7 is punctured, the puncture device 106 moves downward and resets, and the puncture device 106 resets and squeezes the lifting frame 111 downward and resets again, and the pressure spring 114 returns to the initial state, and the lifting frame 111 resets so that the second rotating shaft drives the rubber wheel 113 to reset.
