Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery recycling, and in particular to a high-efficiency sorting device based on lithium battery recycling. Background Art

[0002] With the rapid development of the new energy industry, lithium batteries are increasingly being used in applications such as electric vehicles and energy storage systems. However, as lithium batteries age, their performance gradually declines, becoming unable to meet initial requirements. To maximize the value of lithium batteries and reduce resource waste and environmental pollution, lithium battery recycling technology has emerged.

[0003] Lithium battery second-use refers to the testing, sorting, and reassembly of retired or discarded lithium batteries, enabling their continued use in other applications, such as low-speed electric vehicles and energy storage power stations. Sorting equipment is a key component of lithium battery second-use, and its performance directly impacts the efficiency and cost of second-use.

[0004] The existing lithium battery recycling and sorting equipment has the following main shortcomings:

[0005] Low sorting efficiency: Most existing sorting devices use manual sorting or semi-automatic sorting methods, which have low sorting efficiency and cannot meet the needs of large-scale production.

[0006] Low sorting accuracy: Existing sorting devices have low accuracy in detecting the internal charge of lithium batteries, which can easily lead to misjudgment, causing usable lithium batteries to be misjudged as unusable, resulting in a waste of resources.

[0007] Poor adaptability: Existing sorting devices have poor adaptability to different types of lithium batteries, and require frequent replacement of sorting molds or adjustment of sorting parameters, which increases sorting costs and operational difficulty.

[0008] Low degree of automation: The existing sorting equipment has a low degree of automation and requires a lot of manual intervention, which increases labor intensity and production costs.

[0009] Therefore, this proposal proposes an efficient sorting device based on the cascade utilization of lithium batteries to solve the above problems. Utility Model Content

[0010] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a high-efficiency sorting device based on the cascade utilization of lithium batteries.

[0011] To achieve the above objectives, the technical solution of the present invention is implemented as follows: an efficient sorting device based on the cascade utilization of lithium batteries, comprising a material guide ramp, a reusable recycling trough, and an unreusable recycling box, wherein the material guide ramp and the reusable recycling trough are connected by a sorting component, and the unreusable recycling box is distributed directly below the sorting component;

[0012] The sorting component specifically includes the following structure:

[0013] A sorting platform communicating with the slope of the material guide ramp and the surface of the available recovery trough;

[0014] A top platform located directly above the sorting platform;

[0015] Measuring components distributed on the left and right sides below the top platform;

[0016] A distance adjustment mechanism installed in the top platform for synchronously adjusting the distance between the measuring components on both sides;

[0017] A material blocking assembly installed at the front end of the top platform;

[0018] A downward-turnable outlet door is installed in the sorting table.

[0019] Preferably, a turning motor capable of driving the output door to turn 90° is installed on the right side wall of the sorting table.

[0020] Preferably, the sorting platform and the top platform are connected by pillars distributed at four corner ends.

[0021] Preferably, the material blocking assembly specifically includes the following structure:

[0022] A mounting frame installed at the center of the front end of the top platform;

[0023] a second telescopic cylinder mounted on the mounting frame;

[0024] A material blocking plate is docked at the telescopic end of the second telescopic cylinder, and when the material blocking plate moves downward, it blocks the front of the sorting platform.

[0025] Preferably, the distance adjustment mechanism specifically includes the following structure:

[0026] A dual-axis reduction motor installed at the bottom center of the top platform;

[0027] Drive screws connected to the output ends of both sides of the dual-axis reduction motor respectively;

[0028] The screw sleeves are respectively threadedly sleeved on the driving screws on both sides, and the bottom tube walls of the screw sleeves on both sides are respectively connected to the top centers of the measuring components on both sides.

[0029] Preferably, the measuring component specifically includes the following structure:

[0030] A side plate connected to the bottom wall of the screw sleeve on the same side;

[0031] Contact electrode sheets distributed on the inner surface of the side panels.

[0032] Preferably, side guide plates are provided on both the left and right sides of the top of the material guiding ramp, and first telescopic cylinders are installed at the centers of the left and right edges of the material guiding ramp to drive the side guide plates on both sides to slide toward the center.

[0033] The beneficial effects of the present invention are as follows:

[0034] Improve sorting efficiency: The device automatically transports the cylindrical lithium batteries to be tested to the sorting assembly through the material guide ramp, realizing a continuous operation process, reducing manual intervention, and greatly improving sorting efficiency.

[0035] Precision Sorting: The measuring component within the sorting unit detects the internal charge level of lithium batteries, while the distance adjustment mechanism adjusts based on battery size to ensure accurate measurement. The contact electrode can also detect the size, shape, or electrical characteristics of lithium batteries, further enhancing sorting accuracy and enabling accurate classification of usable and unusable lithium batteries.

[0036] Adaptable to Multiple Models: The side guide plates on the guide ramp slide toward the center via a first telescopic cylinder, ensuring that lithium batteries of different sizes are always centered along the ramp, ensuring accurate entry into the sorting assembly. A distance adjustment mechanism simultaneously adjusts the distance between the measuring assemblies on both sides to accommodate lithium batteries of varying sizes, enhancing the device's versatility and applicability.

[0037] Automated Operation: The retaining plate in the retaining assembly, driven by a second telescopic cylinder, automatically blocks the rolling of lithium batteries, forcing them to remain on the sorting table awaiting inspection. The discharge gate, controlled by a flip motor, automatically directs unusable lithium batteries into the unusable recycling bin based on inspection results, while usable lithium batteries are automatically rolled into the usable recycling trough. This automates the entire sorting process, reducing labor intensity and improving work efficiency.

[0038] Rational use of resources: The device can recycle usable lithium batteries and unusable lithium batteries into usable recycling slots and unusable recycling bins respectively, realizing the cascade utilization of lithium batteries, improving resource utilization, reducing resource waste, and being beneficial to environmental protection and sustainable development.

[0039] In summary, this efficient sorting device based on the cascade utilization of lithium batteries achieves efficient lithium battery sorting and rational resource utilization through automated operating procedures, precise detection and sorting functions, and adaptability to different lithium battery models, with significant economic and environmental benefits. It not only improves sorting efficiency and accuracy, reduces labor intensity, but also provides reliable technical support for the cascade utilization of lithium batteries, promotes the development of the lithium battery recycling industry, and is of great significance to the realization of resource recycling and sustainable development.

Furthermore, the technical solutions of the various embodiments may be combined with each other, but this must be based on the premise that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0058] Please refer to the instruction manual Figures 1-6 The present invention provides an efficient sorting device based on the cascade utilization of lithium batteries, comprising a material guide ramp 1, a reusable recycling trough 2, and an unusable recycling box 4. The device is characterized in that the material guide ramp 1 and the reusable recycling trough 2 are connected via a sorting component 3, and the unusable recycling box 4 is located directly below the sorting component 3.

[0059] Description of the overall structure of the device:

[0060] A guide ramp 1, located at the top of the device, conveys the cylindrical lithium batteries to be inspected to a sorting assembly 3. Located between the guide ramp 1 and the reusable recycling trough 2, the sorting assembly 3 is responsible for sorting reusable and unusable lithium batteries, directing them to the reusable recycling trough 2 and the unusable recycling bin 4, respectively.

[0061] Guide ramp and side guide plate:

[0062] Side guide plates 11 are located on either side of the top of the ramp 1, guiding the cylindrical lithium batteries to be inspected as they roll down the ramp. First telescopic cylinders 12, mounted at the center of the left and right edges of the ramp, allow the side guide plates 11 to slide toward the center, ensuring that lithium batteries of varying sizes remain centered on the ramp 1, ensuring their accurate entry into the sorting assembly 3.

[0063] Sorting component structure description:

[0064] The sorting assembly 3 includes a sorting platform 31 , a top platform 33 , a measuring assembly 36 , a distance adjustment mechanism 35 , a material blocking assembly 34 and a lead-out gate 32 .

[0065] The sorting platform 31 and the support pillars 311: The sorting platform 31 is used to receive the lithium batteries that roll down the material guide ramp 1 and is connected to the top platform 33 through the support pillars 311 to ensure the stability of the structure.

[0066] Top platform 33 and measuring component 36: The top platform 33 is set directly above the sorting platform 31, and the measuring components 36 are distributed on the left and right sides below the top platform 33, and are mainly responsible for detecting the internal power of the lithium battery.

[0067] Distance adjustment mechanism 35: A distance adjustment mechanism 35 is installed within the top platform 33. This mechanism uses a dual-axis reduction motor 351 to drive two drive screws 352 on either side, which in turn moves a screw sleeve 353 threaded onto the screws. This mechanism synchronously adjusts the distance between the two measuring assemblies 36 to accommodate lithium batteries of varying sizes. The distance adjustment mechanism 35, in conjunction with the measuring assembly 36, ensures accurate lithium battery sorting during the sorting process.

[0068] The blocking assembly 34, mounted at the front end of the top platform 33, comprises a mounting bracket 341, a second telescopic cylinder 342, and a blocking plate 343. When cylindrical lithium batteries roll down the guide ramp 1, the blocking plate 343, driven by the second telescopic cylinder 342, stops the batteries from rolling and temporarily stops them on the sorting platform 31, awaiting detection by the measuring assembly 36.

[0069] The discharge gate 32 is installed inside the sorting platform 31 and is used to flip unusable lithium batteries into the unusable recycling bin 4 below. The discharge gate 32 is controlled by a flip motor 321 installed on the right side wall of the sorting platform 31 and can achieve a 90° flip, ensuring the smooth discharge of unusable lithium batteries.

[0070] Specific structure of measuring component 36:

[0071] Measuring assembly 36 consists of a side plate 361 and contact electrodes 362. Side plate 361 is connected to the bottom wall of screw sleeve 353, and its position is adjusted by the action of distance adjustment mechanism 35. Contact electrodes 362 are located on the inner surface of side plate 361 and are used to detect the size, shape, or electrical characteristics of lithium batteries to determine their usability.

[0072] Working process:

[0073] The cylindrical lithium battery to be tested rolls onto the sorting platform 31 via the guide ramp 1. The blocking assembly 34 prevents the lithium battery from continuing to roll, causing it to remain above the sorting platform. The measuring assembly 36 detects the relevant parameters of the lithium battery and adjusts its position via the distance adjustment mechanism 35 to accommodate lithium batteries of different sizes. If the test results indicate that the lithium battery is unusable, the flip motor 321 drives the export gate 32 to flip 90°, exporting the lithium battery to the unusable recycling bin 4. If the lithium battery is usable, the blocking plate 343 in the blocking assembly 34 is recovered, and the usable lithium battery rolls through the sorting platform 31 into the usable recycling tank 2.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
