Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, and in particular to a lithium battery sorting and recycling device. Background Technology

[0002] Reusing spent lithium batteries not only avoids resource waste and makes the most of resources, but also reduces the environmental pollution caused by metal ions contained in the batteries. Currently, the process typically involves separating the valuable metals and non-metals from the batteries, and then recycling the valuable metals and non-metals from the lithium battery components separately.

[0003] Patent document CN113145504A discloses a sorting device for lithium battery cells, including a machine body. A placement box is installed at one end of the machine body. A rotating shaft of a motor on a fixed base behind the placement box passes through one side of the placement box, and a feeding wheel is installed on the rotating shaft. The ring teeth on the feeding wheel stack the battery cells, thereby pushing them into the slots on the chain plate by a telescopic rod. At the same time, a parallel motor is installed in the cavity inside the machine body, and a gear is installed on the rotating shaft of the motor. The outer ring of the gear is connected to the inner ring of the chain plate. The outer ring of the chain plate has multiple slots, and the chain plate passes through a fixed slot fixed on the machine body. The diameter of the slot is the same as the diameter of the battery cell. A parallel hydraulic cylinder is located on the same side of the motor. The hydraulic cylinder pushes the fixed plate to move the cylinder on the mounting base up and down, pushing the battery cells in the slots on the chain plate, so that they fall into the collection box, achieving the sorting purpose.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: manual screening is required, which reduces work efficiency, and human error is prone to occur, affecting the quality of sorting and recycling; furthermore, manual observation is required to check whether the recycling bins for receiving sorted parts are full, and manual replacement is necessary when full, further reducing work efficiency. Therefore, a lithium battery sorting and recycling device is designed to provide an alternative technical solution to the above-mentioned technical problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a lithium battery sorting and recycling device to address the aforementioned technical problems, thereby solving the technical issues of needing to combine manual screening with manual observation or manual replacement of recycling bins.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A lithium battery sorting and recycling device, comprising:

[0008] The first conveying device is used to convey lithium battery components;

[0009] The testing mechanism is located on the first conveying device and is configured to classify lithium battery components based on image detection, wherein the lithium battery components are detected and classified into two categories: valuable metals and non-metals.

[0010] A sorting mechanism, also mounted on the first conveying device and located on one side of the detection mechanism, is used to drive relative movement between valuable metal and non-metal lithium battery components; and

[0011] Two second conveying devices are provided, each equipped with multiple recycling bins. The recycling bins are used to receive valuable metal or non-metal lithium battery components pushed by the sorting mechanism. The second conveying device is used to drive one of the recycling bins to correspond to the sorting mechanism.

[0012] In a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, two guide troughs and a first proximity sensor are arranged opposite to each other on the first conveying device. The guide troughs are used to receive two types of lithium battery components, namely valuable metals and non-metals. The first proximity sensor is used to sense the recycling bins on the second conveying device so that one of the recycling bins corresponds to the guide trough.

[0013] As a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, the detection mechanism includes a bracket, an industrial camera fixed to the top of the bracket, and a second proximity sensor fixed to one side of the bracket. The industrial camera is used to photograph lithium battery components to generate image information, and the second proximity sensor is used to sense lithium battery components on the first conveying device.

[0014] As a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, the sorting mechanism includes a linearly movable pusher frame, which is disposed between two guide troughs. The pusher frame is used to transfer two types of lithium battery components, namely valuable metals and non-metals, from the first conveying device to one of the guide troughs.

[0015] As a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, the sorting mechanism further includes linear modules that are interleaved and fixed to the first conveying device. The pusher is driven by the linear modules, and the linear modules are used to drive the pusher to move linearly back and forth.

[0016] In a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, the two second conveying devices are further provided with multiple bases for placing recycling boxes, and weight sensors are embedded in the bases.

[0017] As a preferred embodiment of the lithium battery sorting and recycling device provided by this utility model, it also includes a PLC controller. The PLC controller is used to receive image information and classify it into two categories: valuable metals and non-metals, and to control the movement direction and stroke of the linear module; it is also used to receive the weight information of the weight sensor and, in conjunction with the first proximity sensor, control the conveying stroke of the second conveying device to switch the corresponding guide trough of the recycling box.

[0018] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0019] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0020] The present invention provides a lithium battery sorting and recycling device, which continuously transports lithium battery components through a first conveying device, and the detection mechanism determines the category of lithium battery components. Then, the sorting mechanism places different categories of lithium battery components into recycling bins on one or the other side, thereby eliminating the need for manual screening, greatly reducing the error rate, and thus improving sorting efficiency.

[0021] The present invention provides a lithium battery sorting and recycling device. Since the recycling box is located on the second conveying device, it can drive the recycling box to move on the second conveying device, allowing another recycling box to switch to the corresponding one, thus eliminating the need for manual observation and switching, thereby further improving the sorting efficiency.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1 and Figure 2 As shown, this lithium battery sorting and recycling device includes a first conveying device 1, a detection mechanism 2, a sorting mechanism 4, and two second conveying devices 5. The first conveying device 1 is used to successively convey dismantled lithium battery components from one end to the other end for detection by the detection mechanism 2 located at the other end of the first conveying device 1. Specifically, the detection mechanism 2 is used to detect and classify the lithium batteries corresponding to their own positions based on images, so that the lithium battery components are detected and classified into two categories: valuable metals and non-metals.

[0034] The sorting mechanism 4 is also located at the other end of the first conveying device 1 and on one side of the detection mechanism 2. The sorting mechanism 4 is used to push the lithium battery parts of valuable metal and non-metal respectively. For example, the lithium battery parts of valuable metal are pushed to one side and the lithium battery parts of non-metal are pushed to the other side, so as to achieve the sorting and recycling of lithium battery parts of valuable metal and non-metal.

[0035] Two second conveying devices 5 are respectively located on both sides of the first conveying device 1, and multiple recycling bins 6 are equally spaced on each of the two second conveying devices 5. The recycling bins 6 are used to receive lithium battery components pushed by the sorting mechanism 4. For example, the recycling bin 6 on one of the second conveying devices 5 specifically receives lithium battery components that are valuable metals, while the recycling bin 6 on the other second conveying device 5 receives non-metallic components.

[0036] It should be noted that the first conveying device 1 and the second conveying device 5 have the same structure, as can be found in the prior art. For example, they both include a support leg assembly, a frame fixed on the support leg assembly, multiple rollers rotatably connected in the frame, a belt sleeved on the multiple rollers, and a motor fixed between the frame and the support assembly and coaxially connected to one of the rollers. The motor drives the rollers to rotate, so that the belt rotates outside the multiple rollers, and the rotation of the belt conveys the lithium battery parts placed on top of it.

[0037] like Figure 2 As shown, and for reference Figure 1 On both sides of the other end of the first conveying device 1, there are guide troughs 7. The top of the guide troughs 7 extends to the top of the first conveying device 1, and the bottom extends to the second conveying device 5. The lithium battery parts pushed by the sorting mechanism 4 slide down the guide troughs 7 into the recycling bins 6 on the second conveying device 5. In order to ensure that the parts fall accurately into the recycling bins 6 after passing through the guide troughs 7, first proximity sensors 8 are fixed on both sides of the first conveying device 1, which are located below the two guide troughs 7. The first proximity sensors 8 are used to sense the position of the recycling bins 6 on the second conveying device 5. That is, by sensing the position of the recycling bins 6 through the first proximity sensors 8, the second conveying device 5 stops working, and the second conveying device 5 moves the recycling bins 6 to correspond to the guide troughs 7 and then stops moving, so that the recycling bins 6 are accurately aligned with the guide troughs 7.

[0038] like Figure 3 As shown, and for reference Figure 2 The detection mechanism 2 includes a bracket 21, an industrial camera 22 fixed to the top of the bracket 21, and a second proximity sensor 23 fixed to one side of the bracket 21. Specifically, when the second proximity sensor 23 senses that the lithium battery parts are being transported into the bracket 21, it triggers the first conveying device 1 to stop working, allowing the parts to be temporarily located in the bracket 21. Then, the industrial camera 22 above captures images of the parts to determine the category of the parts (see below for details). Finally, the first conveying device 1 transports the detected parts. Specifically, the transport distance is such that the parts enter the operable part of the sorting mechanism 4, and the parts on the adjacent side enter the sensing range of the second proximity sensor 23. The sorting mechanism 4 pushes the parts to one side or to the other side into the recycling bin 6 based on the category of the parts.

[0039] In some embodiments (not shown in the figure), the detection mechanism 2 includes a bracket 21, a brake and an electroscope disposed at the top of the bracket 21, and a second proximity sensor 23 fixed to one side of the bracket 21. Specifically, the brake is a cylinder or electric cylinder and is vertically fixed to the bracket 21. The contact of the electroscope is fixed to the piston end of the brake with its contact facing downward. The brake drives the contact of the electroscope to descend and contact the lithium battery component. The component is detected by whether it is charged or not, and is divided into valuable metals and non-metals. The second proximity sensor 23 has the same function as the previous example, as described above.

[0040] like Figure 4 As shown, and for reference Figure 3 The sorting mechanism 4 consists of a linear module 42 and a pusher 41 located on the linear module 42. Specifically, the linear module 42 has a screw braking structure, as described in the prior art. For example, the linear module 42 is provided with a slide that moves back and forth driven by a screw. One side of the middle part of the pusher 41 is fixed on the slide. The two sides of the pusher 41 that are connected to the slide extend downward and are located between the two guide grooves 7. The operable part of the sorting mechanism 4 is the area between the two downwardly extending parts of the pusher 41. Thus, the pusher 41 is moved to one side or to the other side by the slide. When the pusher 41 moves, the downwardly extending parts on the pusher 41 drive the parts to move.

[0041] like Figure 5 As shown, and for reference Figure 1 The second conveying device 5 is also equipped with multiple bases 9 for placing recycling bins 6. By placing the recycling bins 6 on the bases 9, the recycling bins 6 are stably positioned on the second conveying device 5. It should be noted that the conveying length of the second conveying device 5 is not limited to the length shown in the figure, so that it can carry and convey a larger number of recycling bins 6.

[0042] A weight sensor 3 is embedded in the base 9. The weight sensor 3 is used to sense the weight of the recycling bin 6. It is set to trigger the second conveying device 5 to work after sensing a certain weight value, so that the recycling bin 6 that has reached the braking weight moves and the recycling bin 6 on the adjacent side is aligned with the second proximity sensor 23. Finally, the second proximity sensor 23 triggers the second conveying device 5 to stop working by sensing the recycling bin 6, thereby achieving automatic switching of the recycling bin 6, so that no manual observation or manual transfer is required.

[0043] In some embodiments, the recycling bin 6 is equipped with an inductive counter. After the inductive component enters the recycling bin 6 a certain number of times, the second conveying device 5 performs the same action as in the previous example.

[0044] Based on the above, it also includes a PLC controller (not shown in the figure). The PLC controller integrates an image processing module and a relay module. The image processing module is used to receive image information captured by the industrial camera 22 and compare it with the imported image information of all lithium battery components belonging to both valuable metal and non-metal categories. Under the action of a computer-readable program, it determines whether the component is a valuable metal or non-metal lithium battery component. For example, when it is determined to be a valuable metal lithium battery component, the relay module controls the linear module 42 to drive the pusher 41 to move to one side to the maximum stroke and then reset back to the middle. Conversely, it moves in the opposite direction and resets.

[0045] The first conveying device 1 is controlled to start and stop based on the first proximity sensor 8 via the intermediate device of the relay module; the second conveying device 5 is controlled to start and stop based on the position information of the second proximity sensor 23 and the weight information of the weight sensor 3 or the number of counters.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
