Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery classification and screening, and particularly to an automatic machine suitable for lithium battery classification and screening. Background Art

[0002] A large number of non-renewable and highly valuable metal resources are contained in waste lithium batteries. The cathode plate material in the lithium battery is lithium cobalt oxide powder, and the anode plate material is graphite powder. A large amount of metal materials such as nickel, copper, and aluminum are contained in both the cathode plate and the anode plate. If waste or unqualified lithium batteries can be effectively recycled and processed, it can not only reduce the environmental pressure caused by waste batteries, but also avoid waste of metal resources such as cobalt and nickel.

[0003] An automatic disassembly and sorting machine for the positive and negative electrodes and diaphragm of a lithium battery such as "CN110364779A" includes: a to-be-decomposed electrode feeding mechanism arranged on the mounting plate of the frame, which is used to provide lithium batteries to be decomposed; a diaphragm collecting mechanism located above the to-be-decomposed electrode feeding mechanism, which is used to collect the diaphragms of the lithium batteries on the to-be-decomposed electrode feeding mechanism; a positive electrode decomposition and transplanting robotic arm and a negative electrode decomposition and transplanting robotic arm arranged at both ends of the to-be-decomposed electrode feeding mechanism, which are respectively used to grab the positive and negative electrodes of the lithium battery and place the positive and negative electrodes of the lithium battery into the positive electrode collection bin and the negative electrode collection bin respectively. The present invention realizes the automatic disassembly of the positive and negative electrodes and the diaphragm of the lithium battery, classifies the disassembled positive and negative electrodes, reduces the contact time between personnel and the lithium battery electrodes, thereby reducing the harm to operating personnel, improving the automation degree of the lithium battery disassembly industry, saving manpower, and reducing the operating costs of lithium battery disassembly manufacturers.

[0004] However, in the prior art, during the battery screening process, generally a large number of batteries are screened. In order to improve the screening efficiency, a large number of batteries are loaded in the feeding box during feeding. During the falling process of the batteries, they are likely to collide with the inner wall of the feeding box or between the batteries. If the number of impacts is large or the falling height is large, the batteries are likely to be damaged, thus affecting the quality of the batteries. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the batteries are easily damaged due to collision during the sorting and falling process.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An automated machine applicable to the classification and screening of lithium batteries, comprising a sorting frame, a blanking box, and a sorting plate. The sorting plate is arranged on the sorting frame. A plurality of sorting grooves are provided on the sorting plate. A pushing groove is provided on the sorting plate at one end of the sorting groove. The pushing groove is communicated with the sorting groove. A collection box is provided on the sorting frame. The end of the sorting groove away from the pushing groove is detachably communicated with the collection box. A pushing mechanism is provided in the pushing groove. There are two blanking boxes respectively arranged at both ends of the sorting plate. A screening box is provided above the blanking box. The lower end of the screening box is respectively communicated with the two blanking boxes. Two screening cylinders are rotatably provided in the screening box and are respectively communicated with the upper parts of the two blanking boxes below. A guiding roller is rotatably provided below the interior of the blanking box. A plurality of guiding strips are spacedly provided on the inner wall of the blanking box above the guiding roller. A plurality of buffer strips are spacedly provided on both sides of the guiding strip. The upper part of the blanking box is communicated with the discharging end of the screening box through a buffer box. A pushing plate is slidably provided in the buffer box. A testing mechanism is provided outside the guiding roller. The lower end of the blanking box is communicated with the pushing groove.

[0007] As a preferred embodiment, the buffer strip is arranged in a semi-cylindrical structure on the side wall of the guiding strip. An assembly groove is opened above the buffer strip. A long strip is provided in the assembly groove through a first spring. The outer wall of the long strip is made of rubber and is arranged in an arc structure. By setting the surface of the buffer strip as an arc-shaped material, it is convenient for the battery to slide smoothly on the buffer strip. By providing a long strip in the buffer strip through a first spring, the buffering effect when the battery drops onto the long strip can be effectively increased, improving the protection of the battery.

[0008] As a preferred embodiment, a sliding groove is provided on the inner wall of the buffer box. Both ends of the pushing plate are slidably arranged in the sliding groove through sliders. A gear is rotatably provided at one end of a slider away from the pushing plate. The gear is meshed with one side of the sliding groove. The gear is driven to rotate by a first motor. By driving the gear to rotate by the first motor, the pushing plate is driven to slide relative to the sliding groove, achieving the effect of pushing and dispersing the batteries.

[0009] As a preferred embodiment, a rotating plate is rotatably provided on one side of the upper end of the guiding strip. The rotating plate and the guiding strip are assembled and connected through a second spring below. By providing the rotating plate, the moving range of the battery in the buffer box when the battery is pushed by the pushing plate can be increased, thereby achieving a more random effect of the battery falling to different positions in the blanking box, and avoiding the effect of a large accumulation of batteries in some positions.

[0010] As a preferred embodiment, the guiding roller is rotatably arranged inside the blanking box. The guiding roller is driven to rotate by a second motor. A limiting groove for engaging with the battery is provided at the edge of the guiding roller. Inclined plates are provided in the blanking box on both sides of the guiding roller. The testing mechanism is arranged on the blanking box below the inclined plates. By driving the second motor, the guiding roller is driven to rotate. The battery falling between the guiding strips directly falls into the limiting groove. By rotating the guiding roller, the battery in the limiting groove can be rotated to the position of the testing mechanism, and the battery is tested by the testing mechanism.

[0011] As a preferred embodiment, the testing mechanism includes a detection device and a cylinder. A control box is provided on the blanking box. A single-chip microcomputer is arranged inside the control box. The detection device is arranged on the sorting rack. A detection slot is formed in the side wall of the blanking box. The detection slot is communicated with a limiting groove. A detection head on the detection device is slidably arranged in the detection slot. The detection head is assembled and connected to the outer wall of the blanking box through the cylinder. When the battery in the limiting groove passes through the detection slot, the cylinder contracts, driving the detection head to move towards the battery until the detection head contacts the end face of the battery to realize power-on for detection. The detection device can be a capacity detection device. The detected result data is converted into an electrical signal by the single-chip microcomputer and transmitted to the pushing mechanism at the corresponding position. When the battery passes through the pushing mechanism, the pushing mechanism is driven to realize the classification of the battery.

[0012] As a preferred embodiment, a conveyor belt is arranged in the pushing slot. A plurality of limiting strips are arranged at intervals on the conveyor belt. The distance between adjacent limiting strips is adapted to the length of the battery. There are two conveyor belts and they are symmetrically arranged. The feeding end of the conveyor belt is located directly below the discharge port of the blanking box. The discharge ends of the two conveyor belts are arranged oppositely. By arranging the conveyor belt, it is used to guide the tested battery into the pushing slot. By arranging the limiting strips, it is used to separate adjacent batteries to ensure that the battery entering the sorting slot is correct.

[0013] As a preferred embodiment, there are a plurality of pushing mechanisms which are respectively corresponding to the sorting slots. The pushing mechanism includes a telescopic rod, a third spring, a first magnetic block and a second magnetic block. The first magnetic block is electrically connected to an external power supply. The second magnetic block is assembled and connected to the pushing slot. The first magnetic block and the second magnetic block repel each other. The first magnetic block and the second magnetic block are assembled and connected through the telescopic rod and the third spring. The third spring is sleeved outside the telescopic rod. When a corresponding pushing mechanism receives the electrical signal transmitted by the single-chip microcomputer in the control box, the first magnetic block in the pushing mechanism is powered on. At this time, a repulsive magnetic force is generated between the first magnetic block and the second magnetic block, and the first magnetic block and the second magnetic block quickly separate, which can just push the battery on the conveyor belt into the sorting slot to achieve the sorting effect.

[0014] As a preferred embodiment, a flap is rotatably provided at one end of the sorting tank close to the pushing tank. The upper part of the flap is rotatably connected to the upper part of the pushing tank through a torsion spring. By providing the flap, it is convenient to limit the batteries on the conveyor belt and prevent the batteries from directly rolling into the non-corresponding sorting tank. Only when the first magnetic block pushes the battery, the battery can be pushed and the flap can be pushed open against it.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows. 1. The batteries sorted by size in the present invention are respectively introduced into the buffer boxes above the two discharging boxes. Through the pushing of the push plates in the buffer boxes, the batteries can be randomly pushed between any two adjacent guiding strips. When the battery passes between the two guiding strips, since the distance between the adjacent guiding strips is just slightly larger than the diameter of the battery, the battery can smoothly slide between the guiding strips. By arranging a plurality of buffer strips at intervals on both sides of the guiding strips, the battery can directly contact the buffer strips after falling a short distance to obtain buffering, and the surface of the buffer strips is arranged in an arc structure, which can make the battery fall more smoothly when passing through the buffer strips. By arranging a plurality of buffer strips at intervals, the falling speed of the battery can be greatly reduced, achieving the effect of protecting the battery.

[0016] 2. In the present invention, the first motor is driven to drive the gear to rotate, and then the push plate slides relative to the chute, achieving the effect of pushing and dispersing the batteries.

[0017] 3. In the present invention, through the provided rotating plate, the moving range of the battery in the buffer box when the battery is pushed by the push plate can be increased, so as to achieve a more random effect that the battery falls into different positions in the discharging box, and the effect of avoiding a large accumulation of batteries in some positions can be achieved.

[0018] 4. In the present invention, by providing the flap, it is convenient to limit the batteries on the conveyor belt and prevent the batteries from directly rolling into the non-corresponding sorting tank. Only when the first magnetic block pushes the battery, the battery can be pushed and the flap can be pushed open against it. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 - Figure 10, the present invention provides a technical solution: an automated machine applicable to the classification and screening of lithium batteries, including a sorting frame 1, a blanking box 2 and a sorting plate 3. The sorting plate 3 is arranged on the sorting frame 1. A plurality of sorting grooves 4 are provided on the sorting plate 3. A pushing groove 5 is provided on the sorting plate 3 at one end of the sorting groove 4. The pushing groove 5 is communicated with the sorting groove 4. A collecting box 6 is provided on the sorting frame 1. One end of the sorting groove 4 away from the pushing groove 5 is detachably communicated with the collecting box 6. A pushing mechanism is provided in the pushing groove 5. There are two blanking boxes 2 which are respectively arranged at both ends of the sorting plate 3. A screening box 7 is provided above the blanking box 2. The lower end of the screening box 7 is respectively communicated with the two blanking boxes 2. A screening cylinder 8 is rotatably provided in the screening box 7. There are two screening cylinders 8 and the lower parts are respectively communicated with the upper parts of the two blanking boxes 2. A guiding roller 9 is rotatably provided below the inner part of the blanking box 2. A plurality of guiding strips 10 are spacedly arranged on the inner wall of the blanking box 2 above the guiding roller 9. A plurality of buffer strips 12 are spacedly arranged on both sides of the guiding strip 10. The upper part of the blanking box 2 is communicated with the discharging end of the screening box 7 through a buffer box 11. A push plate 13 is slidably provided in the buffer box 11. A testing mechanism is provided outside the guiding roller 9. The lower end of the blanking box 2 is communicated with the pushing groove 5.

[0023] As Figure 1 - Figure 10 shown, the buffer strip 12 is arranged on the side wall of the guiding strip 10 in a semi-cylindrical structure. An assembly groove 141 is opened above the buffer strip 12. A long strip 143 is provided in the assembly groove 141 through a first spring 142. The outer wall of the long strip 143 is made of rubber and is arranged in an arc structure. By setting the surface of the buffer strip 12 as an arc material, it is convenient for the battery to slide smoothly on the buffer strip 12. By providing the long strip 143 in the buffer strip 12 through the first spring 142, the buffer effect when the battery drops onto the long strip 143 can be effectively increased, and the protection of the battery can be improved.

[0024] As Figure 1 - Figure 10 shown, a sliding groove 151 is provided on the inner wall of the buffer box 11. Both ends of the push plate 13 are slidably arranged in the sliding groove 151 through sliders 152. A gear 153 is rotatably provided at one end of a slider 152 away from the push plate 13. The gear 153 is meshed with one side of the sliding groove 151. The gear 153 is driven to rotate by a first motor 154. By driving the first motor 154 to drive the gear 153 to rotate, the push plate 13 is driven to slide relative to the sliding groove 151, so as to achieve the effect of pushing and dispersing the battery.

[0025] As Figure 1 - Figure 10As shown in the figure, a rotating plate 161 is rotatably arranged on one side of the upper end of the guiding bar 10. A second spring 162 is assembled and connected between the lower part of the rotating plate 161 and the guiding bar 10. By providing the rotating plate 161, the moving range of the battery in the buffer box 11 when the battery is pushed by the pushing plate 13 can be increased, so as to achieve a more random effect that the battery falls to different positions in the blanking box 2, and the effect of avoiding a large accumulation of batteries in some positions can be achieved.

[0026] As Figure 1 - Figure 10 shown in the figure, a guiding roller 9 is rotatably arranged inside the blanking box 2. The guiding roller 9 is driven to rotate by a second motor 171. A limiting groove 172 engaged with the battery is arranged at the edge of the guiding roller 9. Inclined plates 173 are arranged in the blanking box 2 on both sides of the guiding roller 9. The testing mechanism is arranged on the blanking box 2 below the inclined plates 173. By driving the second motor 171, the guiding roller 9 is driven to rotate. The battery falling between the guiding bars 10 directly falls into the limiting groove 172. The battery in the limiting groove 172 can be rotated to the position of the testing mechanism by the rotation of the guiding roller 9, and the battery is tested by the testing mechanism.

[0027] As Figure 1 - Figure 10 shown in the figure, the testing mechanism includes a detection device 181 and a cylinder 182. A control box 183 is arranged on the blanking box 2. A single-chip microcomputer is arranged inside the control box 183. The detection device 181 is arranged on the sorting rack 1. A detection slot 184 is opened on the side wall of the blanking box 2. The detection slot 184 is communicated with a limiting groove 172. A detection head 185 on the detection device 181 is slidably arranged in the detection slot 184. The detection head 185 is assembled and connected with the outer wall of the blanking box 2 through the cylinder 182. When the battery in the limiting groove 172 passes through the detection slot 184, the cylinder 182 contracts, driving the detection head 185 to move towards the battery until the detection head 185 contacts the end face of the battery to realize power-on for detection. The detection device can be a capacity detection device. The detected result data is converted into an electrical signal by the single-chip microcomputer and transmitted to the pushing mechanism at the corresponding position. When the battery passes through the pushing mechanism, the pushing mechanism is driven to realize the classification of the battery.

[0028] As Figure 1 - Figure 10 shown in the figure, a conveyor belt 191 is arranged in the pushing slot 5. A plurality of limiting bars 192 are arranged at intervals on the conveyor belt 191. The distance between adjacent limiting bars 192 is adapted to the length of the battery. There are two conveyor belts 191 and they are symmetrically arranged. The feeding end of the conveyor belt 191 is directly below the discharge port of the blanking box 2. The discharge ends of the two conveyor belts 191 are arranged opposite to each other. By providing the conveyor belt 191, it is used to guide the detected battery into the pushing slot 5. By providing the limiting bars 192, it is used to separate adjacent batteries to ensure that the battery entering the sorting slot 4 is correct.

[0029] As Figure 1 - Figure 10 shown, there are multiple pushing mechanisms which are respectively connected to the corresponding sorting grooves 4. The pushing mechanism includes a telescopic rod 201, a third spring 202, a first magnet 203 and a second magnet 204. The first magnet 203 is electrically connected to an external power supply. The second magnet 204 is assembled and connected to the pushing groove 5. The first magnet 203 and the second magnet 204 repel each other. The first magnet 203 and the second magnet 204 are assembled and connected through the telescopic rod 201 and the third spring 202. The third spring 202 is sleeved outside the telescopic rod 201. When a corresponding pushing mechanism receives an electrical signal transmitted by the single-chip microcomputer in the control box 183, the first magnet 203 in the pushing mechanism is powered on. At this time, a repulsive magnetism is generated between the first magnet 203 and the second magnet 204, and the first magnet 203 and the second magnet 204 quickly separate, and the battery located on the conveyor belt 191 can be just pushed into the sorting groove 4 to achieve the sorting effect.

[0030] As Figure 1 - Figure 10 shown, a flap 21 is rotatably provided at one end of the sorting groove 4 close to the pushing groove 5. The upper part of the flap 21 is rotatably connected to the upper part of the pushing groove 5 through a torsion spring. By providing the flap 21, it is convenient to limit the battery on the conveyor belt 191 and prevent the battery from directly rolling into the non-corresponding sorting groove 4. Only when the first magnet 203 pushes the battery, the battery can be pushed and the flap 21 can be pushed open.

[0031] Working principle: When classifying batteries, the batteries are slowly introduced into the screening box 7 above. By rotating the two screening cylinders 8 in the screening box 7, batteries of different sizes can be classified. The batteries with a larger diameter pass through one screening cylinder 8, and the batteries with a smaller diameter pass through the other screening cylinder 8. The sorted batteries are exported from the screening box 7 below the two screening cylinders 8 and are respectively introduced into the buffer boxes 11 above the two blanking boxes 2. By the pushing of the push plates 13 in the buffer boxes 11, the batteries can be randomly pushed between any two adjacent guiding strips 10. When the batteries pass between the two guiding strips 10, since the distance between the adjacent guiding strips 10 is just slightly larger than the diameter of the battery, the battery can smoothly slide between the guiding strips 10. By arranging a plurality of buffer strips 12 at intervals on both sides of the guiding strips 10, the battery can directly contact the buffer strips 12 after falling a short distance to obtain buffering. Moreover, the surface of the buffer strips 12 is arranged in an arc structure, which can make the battery fall more smoothly when passing through the buffer strips 12. By the plurality of buffer strips 12 arranged at intervals, the falling speed of the battery can be greatly reduced, achieving the protection effect on the battery until the battery steadily falls onto the guiding roller 9. By the rotation of the guiding roller 9, the batteries are sequentially guided downward. When passing through the testing mechanism, the batteries are tested by the testing mechanism, the performance of the batteries is tested and classified, and the test results are transmitted to the corresponding pushing mechanism in the pushing groove 5 through the console. When the battery passes through the position of the corresponding pushing mechanism, the pushing mechanism is driven to push the battery into the corresponding sorting groove 4, achieving the classification and collection effect of the batteries. Through the arranged collection box 6, it is convenient to uniformly collect the batteries stacked in the sorting groove 4.

[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
