Description

Technical Field

[0001] This invention belongs to the field of battery discharge treatment technology, and in particular relates to a battery discharge treatment device. Background Technology

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It differs from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The lithium battery was invented by Thomas Edison. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. Therefore, lithium batteries were not widely used for a long time. However, with the development of microelectronics technology at the end of the 20th century, the increasing miniaturization of devices placed higher demands on power supplies. Lithium batteries subsequently entered a stage of large-scale practical application.

[0003] There are two main methods for safely discharging used lithium batteries. One is physical discharge, which mainly involves discharging the battery through an external load, i.e., by connecting the battery to a resistor. The charge in the battery is dissipated through heat release. However, this method is only for laboratory experiments and is not feasible for large-scale discharge. The other method is chemical discharge, which uses the positive and negative electrode metals of the battery as the cathode and anode, and consumes the residual charge in the battery through an electrolysis process in salt water. Currently, sodium chloride solution is mainly used as the electrolyte and used lithium batteries as the power source for discharge. However, in the actual discharge process, there are many procedures, the workload of workers is high, and the work efficiency is low. Summary of the Invention

[0004] The purpose of this invention is to provide a battery discharge treatment device that solves the technical problems of numerous procedures, high workload for workers, and low work efficiency in existing discharge treatment processes.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A battery discharge treatment device includes two electrically telescopic bases and a support plate fixedly installed on the upper side of the two electrically telescopic bases. A water tank is installed on the upper side of the support plate. A conveyor and a mounting plate are respectively installed on the upper side of the two electrically telescopic bases, and the conveyor is fixedly connected to the side of the mounting plate.

[0007] The bottom surface of the support plate is arrayed with multiple U-shaped guide frames along the transmission direction of the conveyor. The bottom surface of the support plate is equipped with a first electric push rod connected to the U-shaped guide frame. The bottom of the water tank is connected with two electrode telescopic rods that pass through the U-shaped guide frame. The upper side of the mounting plate is equipped with a second electric push rod corresponding to the U-shaped guide frame.

[0008] Optionally, the electrode telescopic rod includes a barrel, a spring installed on the inner wall of the barrel, and a conductive rod connected to the bottom end of the spring and slidably fitted inside the barrel.

[0009] Optionally, the bottom surface of the water tank is provided with a first through hole corresponding to the electrode telescopic rod, and the end of the sealed end of the barrel extends into the water tank through the first through hole.

[0010] Optionally, two electrode telescopic rods corresponding to the U-shaped guide frame are symmetrically arranged on both sides of the first electric push rod.

[0011] Optionally, a pressing plate is provided inside the U-shaped guide frame. A second through hole corresponding to the electrode telescopic rod is opened on the upper side of both the U-shaped guide frame and the pressing plate. The barrel passes through the second through hole located on the U-shaped guide frame, and the conductive rod passes through the second through hole located on the pressing plate. A dome is provided at the bottom end of the conductive rod.

[0012] Optionally, the conveyor end is fixed with a limiting baffle corresponding to multiple U-shaped guide frames.

[0013] Optionally, the electric telescopic base includes a base plate and a top plate connected to the bottom of the water tank. T-shaped grooves are provided on the inner sides of the base plate and the top plate. Two I-shaped sliders slide in the T-shaped grooves. Two transmission plate assemblies are connected between the base plate and the top plate and are hinged to the I-shaped sliders. A dual-shaft extension motor is installed in the T-shaped groove on the base plate. Threaded push rods are installed at both ends of the output shaft of the dual-shaft extension motor. The two threaded push rods in the T-shaped groove are threadedly engaged with the two I-shaped sliders.

[0014] Optionally, the transmission plate assembly includes two transmission plates that rotate and cooperate with each other, with one transmission plate having its two ends hinged to the I-shaped sliders on the top plate and bottom plate respectively, and the other transmission plate having its two ends hinged to the I-shaped sliders on the bottom plate and top plate respectively.

[0015] Optionally, a through hole is provided on one side of the transmission plate, and a rotating shaft is provided in the two third through holes between two adjacent transmission plates. The end of the rotating shaft extending out of the third through hole is provided with an outward flange.

[0016] Optionally, the dual-shaft extension motor is located between the two transmission plate groups, and the vertical cross-section of the T-shaped slide and the I-shaped slider are both T-shaped structures.

[0017] The embodiments of the present invention have the following beneficial effects:

[0018] In one embodiment of the present invention, the distance between the conductive rod and the conveyor is adjusted by opening an electric telescopic base according to the height of the battery. This reduces spring fatigue and prevents the distance between the conductive rod and the conveyor from becoming too low, which would affect the probability of normal contact between the battery and the conductive rod. Then, the first electric push rod is activated to push the U-shaped guide frame down, so that the distance between the bottom of the U-shaped guide frame and the conveyor is less than the height of the battery. Multiple U-shaped guide frames form a channel for guiding the battery transport. The batteries are then transported into the channel in sequence, facilitating stable sliding of the batteries within the channel. Multiple batteries correspond one-to-one with multiple U-shaped guide frames. The two electrode telescopic rods on the U-shaped guide frame are connected to the positive and negative terminals of the battery, respectively. The batteries are then discharged by electrolyzing the brine in the water tank through the two electrode telescopic rods. After the battery is discharged, the corresponding first electric push rod is activated to move the U-shaped guide frame upward to release the limit on the side of the battery. Then, the second electric push rod is activated to push the battery to slide in a direction perpendicular to the transmission direction of the conveyor. Then, the conveyor is activated, and the batteries located at the end away from the limit baffle are sequentially used to fill the empty space. This reduces the discharge process, the workload of the operator, and improves the battery discharge efficiency.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

[0029] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Please see Figure 1-3 As shown, this embodiment provides a battery discharge treatment device, including: two electric telescopic bases 1, a support plate 2 fixedly installed on the upper side of the two electric telescopic bases 1, a water tank 3 installed on the upper side of the support plate 2, a conveyor 4 and a mounting plate 5 respectively installed on the upper side of the two electric telescopic bases 1, and the conveyor 4 and the mounting plate 5 are fixedly connected to the side.

[0031] Multiple U-shaped guide frames 6 are arrayed on the bottom surface of the support plate 2 along the transmission direction of the conveyor 4. The bottom surface of the support plate 2 is equipped with a first electric push rod 7 connected to the U-shaped guide frame 6. The bottom of the water tank 3 is connected with two electrode telescopic rods 8 that pass through the U-shaped guide frame 6. The upper side of the mounting plate 5 is equipped with a second electric push rod 9 corresponding to the U-shaped guide frame 6.

[0032] The distance between the conductive rod 803 and the conveyor 4 is adjusted by opening the electric telescopic base 1 according to the battery height. This helps reduce the elastic fatigue of the spring 802, preventing the distance between the conductive rod 803 and the conveyor 4 from becoming too low, which would affect the probability of normal contact between the battery and the conductive rod 803. Then, the first electric push rod 7 is activated to push the U-shaped guide frame 6 down, so that the distance between the bottom end of the U-shaped guide frame 6 and the conveyor 4 is less than the height of the battery. Multiple U-shaped guide frames 6 form a channel to guide the battery transport. Then, the batteries are transported into the channel in sequence to facilitate stable sliding of the batteries within the channel. Multiple batteries and multiple The U-shaped guide frames 6 correspond one-to-one, and the two electrode telescopic rods 8 on the U-shaped guide frames 6 are connected to the positive and negative terminals of the battery respectively. Then, the salt water in the water tank 3 is discharged through the two electrode telescopic rods 8. After the battery is discharged, the corresponding first electric push rod 7 is activated to move the U-shaped guide frame 6 upward to release the limit on the side of the battery. Then, the second electric push rod 9 is activated to push the battery to slide in a direction perpendicular to the transmission direction of the conveyor 4. Then, the conveyor 4 is activated, and the batteries located at the end away from the limit baffle 11 are filled in the empty space in turn. This makes it easier to reduce the discharge process, reduce the workload of the operator, and improve the battery discharge efficiency.

[0033] The specific electrode telescopic rod 8 includes a barrel 801, a spring 802 installed on the inner wall of the barrel 801, and a conductive rod 803 connected to the bottom end of the spring 802 and slidably fitted inside the barrel 801. The bottom surface of the water tank 3 is provided with a first through hole corresponding to the electrode telescopic rod 8, and the sealed end of the barrel 801 extends into the water tank 3 through the first through hole. Two electrode telescopic rods 8 corresponding to the U-shaped guide frame 6 are symmetrically arranged on both sides of the first electric push rod 7. The U-shaped guide frame 6 is provided with a pressing plate 10. The upper side of the U-shaped guide frame 6 and the pressing plate 10 are provided with a second through hole corresponding to the electrode telescopic rod 8, and the barrel 801 passes through the second through hole located on the U-shaped guide frame 6. The conductive rod 803 passes through the second through hole located on the pressing plate 10. The bottom end of the conductive rod 803 is provided with a dome to facilitate the elastic sliding of the conductive rod 803 and to facilitate the connection between the conductive rod 803 and the battery terminals.

[0034] Specifically, the end of the conveyor 4 is fixed with a limiting baffle 11 corresponding to multiple U-shaped guide frames 6, which facilitates preventing the conveyor 4 from directly transporting the batteries in the channel away.

[0035] The specific electric telescopic base 1 includes a base plate 102 and a top plate 103 connected to the bottom of the water tank 3. T-shaped grooves 104 are provided on the inner sides of both the base plate 102 and the top plate 103. Two I-shaped sliders 105 are slidably fitted within the T-shaped grooves 104. Two transmission plate assemblies, hinged to the I-shaped sliders 105, are fitted between the base plate 102 and the top plate 103. A dual-shaft extension motor 107 is installed within the T-shaped grooves 104 on the base plate 102. Threaded push rods 108 are installed at both ends of the output shaft of the dual-shaft extension motor 107. The two threaded push rods 108 within the T-shaped grooves 104 are threadedly fitted to the two I-shaped sliders 105. The transmission plate assembly includes two transmission plates 106 that rotate with each other, and one transmission plate 106... The two ends of the transmission plate 106 are respectively hinged to the I-shaped sliders 105 on the top plate 103 and the bottom plate 102. The two ends of the transmission plate 106 are respectively hinged to the I-shaped sliders 105 on the bottom plate 102 and the top plate 103. A through hole is provided on one side of the transmission plate 106. A rotating shaft is provided in the two third through holes between two adjacent transmission plates 106. The end of the rotating shaft extending out of the third through hole is provided with an outward flange. The dual-shaft extension motor 107 is located between the two transmission plate groups. The vertical cross section of the T-shaped slide groove 104 and the I-shaped sliders 105 are both T-shaped structures. By turning on the dual-shaft extension motor 107, the threaded push rod 108 is driven to drive the two I-shaped sliders 105 located in the same T-shaped slide groove 104 to slide relative to each other, thereby facilitating the adjustment of the height of the electric telescopic base 1.

[0036] Working principle: Pour sufficient salt water into the water tank 3. Adjust the distance between the conductive rod 803 and the conveyor 4 according to the height of the battery by opening the electric telescopic base 1. Then, open the first electric push rod 7 to push the U-shaped guide frame 6 down, so that the distance between the bottom of the U-shaped guide frame 6 and the conveyor 4 is less than the height of the battery. Multiple U-shaped guide frames 6 form a channel to guide the battery transportation. Then, the batteries are transported into the channel one by one. Multiple batteries correspond one-to-one with multiple U-shaped guide frames 6. The two electrode telescopic rods 8 on the U-shaped guide frame 6 are connected to the positive and negative terminals of the battery, respectively. Then, the salt water in the water tank 3 is electrolyzed and discharged through the two electrode telescopic rods 8. When the battery is discharged, open the corresponding first electric push rod 7 to move the U-shaped guide frame 6 up to release the limit on the side of the battery. Then, open the second electric push rod 9 to push the battery to slide in a direction perpendicular to the transmission direction of the conveyor 4. Then, open the conveyor 4, and the batteries located at the end away from the limit baffle 11 after the batteries have been removed will fill the empty space one by one.
