Description

Technical Field

[0001] This utility model relates to the field of battery cutting device technology, and in particular to a precise and adaptive cutting device for batteries of different sizes. Background Technology

[0002] In recent years, my country's new energy vehicle industry has flourished, with a large number of lithium-ion batteries being produced and used. However, lithium batteries have a limited lifespan, and an increasing number of large-scale lithium battery production lines are facing retirement, creating a huge potential market for the power lithium battery recycling and reuse industry. Only by efficiently solving the environmental pollution and critical resource shortage problems caused by retired batteries can we provide long-term impetus for the sustainable development of the new energy battery industry.

[0003] Battery recycling methods include wet, pyrometallurgical, physical, and biological methods. Among these, physical recycling can effectively reduce carbon emissions, lower overall recycling costs by nearly 40%, and potentially increase resource utilization to over 98%. Physical recycling requires a high degree of precision in the disassembly of power lithium batteries, necessitating the accurate separation of each component—positive electrode, negative electrode, separator, and casing—for separate processing and recycling. Otherwise, the battery components become mixed together as impurities, negating the purpose of physical recycling.

[0004] Currently, regarding the issue of precise disassembly of lithium batteries, a utility model patent (application number CN 201720798396.8) discloses a cross-cutting device and a cutting system. The cross-cutting device includes a frame, a cross-cutting unit mounted on the frame, and a positioning system. The cross-cutting unit is used to cut thin-film batteries and includes a support and a cutter. The support is fixedly mounted on the frame, and the cutter is mounted on the support. The positioning system includes a sensor positioned above the thin-film battery to detect its position. However, this device can only control the cutting length of the thin-film battery, while the size of the cut battery is fixed, making it difficult to accurately cut various types and sizes of retired batteries on the market. If battery cutting equipment cannot adapt to changes in battery size, there will be over-cutting or under-cutting. Over-cutting will result in resource waste, while under-cutting will prevent the core from being removed. This places high demands on the adaptability of battery cutting equipment.

[0005] In view of this, it is necessary to design an improved, precise, adaptive cutting device for batteries of different sizes to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a precise and adaptive cutting device for batteries of different sizes. Through the coordinated operation of various components, the cutting size can be automatically adjusted without the need for frequent changes of battery clamps and sawing components, thereby improving battery cutting efficiency and increasing the recycling rate of waste lithium batteries.

[0007] To achieve the aforementioned utility model objectives, this utility model provides a precise adaptive cutting device for batteries of different sizes, including a feeding component, a feeding component, sensing components disposed on both sides of the feeding component, and a sawing component disposed perpendicular to the feeding direction of the feeding component. The sensing components are disposed between the feeding component and the sawing component, and a control system is provided connecting the two components. The feeding component is equipped with a battery clamp that holds the battery conveyed by the feeding component and pushes the battery to the sawing component under the drive of the feeding component. The sensing components measure the distance between themselves and the two ends of the battery and feed it back to the control system. The control system calculates and analyzes the distance and adjusts the cutting parameters of the sawing component to achieve precise cutting of the battery.

[0008] As a further improvement of this utility model, the sensing component includes two ranging sensors respectively disposed on both sides of the feeding component. The two ranging sensors are symmetrically arranged with respect to the feeding component, and the ranging sensors measure the distance between themselves and the two ends passing through the battery.

[0009] As a further improvement of this utility model, the sawing assembly includes two sawing units respectively disposed on both sides of the feed assembly and arranged opposite to each other. Each sawing unit includes a mounting base, a first linear module disposed on the mounting base, a cutting motor base fixedly connected to the slider of the first linear module, and a cutting motor and saw blade disposed on the cutting motor base. The saw blades of the two sawing units are disposed close to the feed assembly, and the first linear module moves perpendicular to the feed assembly. The sawing unit also includes a servo feed motor disposed at the end of the first linear module, and the servo feed motor controls the movement of the first linear module.

[0010] As a further improvement of this utility model, the feeding component includes a support, a second linear module disposed on the support, and a servo motor disposed at the end of the second linear module.

[0011] As a further improvement of this utility model, the battery clamp includes a clamp connecting plate, a dual-axis cylinder disposed on the clamp connecting plate, a push plate connected to the dual-axis cylinder, and a clamp side baffle perpendicularly connected to the end of the clamp connecting plate. The push plate and the clamp side baffle are arranged parallel to each other, and a space for clamping the battery is formed between the push plate and the clamp side baffle. The clamp connecting plate is fixedly connected to the slider of the second linear module.

[0012] As a further improvement of this utility model, the feeding assembly includes a feeding cylinder disposed above the feeding assembly, a feeding push plate connected to the feeding cylinder, and a baffle bracket disposed on the side of the feeding cylinder. The feeding cylinder is arranged perpendicularly to the feeding assembly, and the baffle bracket and the feeding push plate are disposed on the same side of the feeding assembly. The baffle bracket is arranged perpendicularly to the feeding assembly. The feeding cylinder drives the feeding push plate to move perpendicularly to the feeding assembly, pushing the battery into the battery clamp of the feeding assembly.

[0013] As a further improvement of this utility model, the cutting device also includes a battery limiting seat, which and the material blocking bracket are respectively disposed on both sides of the feeding component, so as to limit the battery in the battery clamp when the feeding component feeds the battery.

[0014] As a further improvement of this utility model, a position adjustment component is provided between the saw blade and the cutting motor. The position adjustment component controls the saw blade to move axially relative to the cutting motor, so as to perform a more precise secondary adjustment of the position of the saw blade.

[0015] As a further improvement of this utility model, the two ranging sensors are respectively disposed on the baffle brackets on both sides of the feeding assembly and on the battery limiting seat.

The battery clamps hold the batteries and, driven by the feeding assembly, push the batteries conveyed by the feeding assembly to the sawing assembly. Simultaneously, the sensing assembly measures the distance between the sensor and the two ends of the battery and feeds the data back to the control system, which calculates the actual size and relative position of the battery.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] Example

[0031] Please see Figure 1 As shown, a precise adaptive cutting device 100 for batteries of different sizes includes a feeding assembly 110, a feeding assembly 120, sensing assemblies 130 disposed on both sides of the feeding assembly 120, and a sawing assembly 140 disposed perpendicular to the feeding direction of the feeding assembly 120. The sensing assemblies 130 are disposed between the feeding assembly 110 and the sawing assembly 140, and a control system connecting the two is provided between the sensing assemblies 130 and the sawing assembly 140. A battery clamp 150 is provided on the feeding assembly 120 for clamping the battery. The battery 160 is conveyed by the feeding assembly 110 and pushed to the sawing assembly 140 by the feeding assembly 120. During the transmission of the battery 160 on the feeding assembly 120, when it passes the sensing assembly 130, the sensing assembly 130 measures the distance between itself and the two ends of the battery 160 and feeds the data back to the control system. The control system calculates the actual size and relative position of the battery 160, and then adjusts the cutting parameters of the sawing assembly 140 according to the calculation results to achieve precise cutting of the battery 160. This cutting device, through the feeding assembly 110, feeding assembly 120, sensing assembly 130, sawing assembly 140, and the control system connecting the sensing assembly 130 and the sawing assembly 140, achieves the purpose of adapting to batteries 160 of different sizes and precisely cutting the battery 160, avoiding over-cutting or under-cutting of the battery 160, ensuring that the core can be accurately ejected from the battery casing, and preventing resource waste.

[0032] Specifically, the sensing component 130 includes two distance sensors 131 respectively disposed on both sides of the feed component 120. The two distance sensors 131 are symmetrically arranged with respect to the feed component 120, that is, the height and horizontal position of the two distance sensors 131 are the same. During the process of the battery 160 being held by the battery clamp 150 and passing through the feed component 120 and approaching the sawing component 140, the two distance sensors 131 can accurately measure the distance between the two ends of the battery 160 and the two distance sensors 131, and then the control system can adjust the cutting parameters of the sawing component 140. The selection and arrangement of the distance sensors 131 can measure the distance between them and the two ends of the battery 160. After being fed back to the control system, not only the length of the battery 160 can be obtained, but also the relative position of the battery 160 can be obtained, realizing the precise cutting of the battery 160. At the same time, accurate cutting can be achieved for batteries 160 of different sizes, and batteries 160 of the same size but in different positions in the battery clamp 150 (the battery limit seat 170 may have a limit error).

[0033] Please see Figure 2 As shown, the sawing assembly 140 includes two sawing units respectively disposed on both sides of the feed assembly 120 and arranged opposite each other. Each sawing unit includes a mounting base 141, a first linear module 142 disposed on the mounting base 141, a cutting motor base 143 fixedly connected to the slider of the first linear module 142, and a cutting motor 144 and saw blades 145 disposed on the cutting motor base 143. The saw blades 145 of the two sawing units are positioned close to the feed assembly 120, and the first linear module 142 moves perpendicular to the feed assembly 120. The sawing unit also includes a servo feed motor 146 disposed at the end of the first linear module 142, which controls the movement of the first linear module 142. Thus, the servo feed motor 146, adjusted by the control system, controls the reciprocating movement of the first linear module 142, thereby adjusting the distance between the two saw blades 145 to fit the two ends of the battery 160 for precise cutting.

[0034] More specifically, a position adjustment component 147 is provided between the saw blade 145 and the cutting motor 144. The position adjustment component 147 controls the axial movement of the saw blade 145 relative to the cutting motor 144, enabling more precise secondary adjustment of the position of the saw blade 145. In application, the position of the saw blade 145 is adjusted by the position adjustment component 147, thus achieving position adjustment of the saw blade 145 relative to the cutting motor 144. In this way, through the movement of the first linear module 142 and the positional movement of the saw blade 145, the positions of the saw blades 145 in both sawing units are more accurate, resulting in higher cutting precision (approximately 0.1mm), good compatibility, high reliability, and a high product qualification rate.

[0035] It should be noted that the control system of this utility model is electrically connected to the sensing component 130 and the sawing component 140. The control system, as the terminal for data processing and parameter adjustment of the sawing component 140, can be a computer or a data control cabinet. The control system can not only calculate the length of the battery, but also the relative position of the battery, and then adjust the cutting parameters of the sawing component 140.

[0036] Please see Figure 3 As shown, the feed assembly 120 includes a support 121, a second linear module 122 disposed on the support 121, and a servo motor 123 disposed at the end of the second linear module 122. The servo motor 123 controls the feed movement of the second linear module 122. The slider of the second linear module 122 is connected to the battery clamp 150 to realize the linear movement of the battery clamp 150 along the feed assembly 120.

[0037] Please see Figure 4 As shown, the battery clamp 150 includes a clamp connecting plate 151, a dual-axis cylinder 152 disposed on the clamp connecting plate 151, a push plate 153 connected to the dual-axis cylinder 152, and a clamp side baffle 154 perpendicularly connected to the end of the clamp connecting plate 151. The push plate 153 and the clamp side baffle 154 are arranged in parallel, and both are arranged in parallel with the feeding direction of the feeding assembly 110. A space for clamping the battery 160 is formed between the push plate 153 and the clamp side baffle 154. The clamp connecting plate 151 is fixedly connected to the slider of the second linear module 122. Thus, when the feeding assembly 110 feeds the battery 160 between the push plate 153 and the clamp side baffle 154, the push plate 153, driven by the dual-axis cylinder 152, securely clamps the battery 160, preventing loosening during the cutting process and affecting the cutting accuracy of the battery 160; and the dual-axis cylinder 152 can flexibly adjust the distance between the push plate 153 and the clamp side baffle 154 to accommodate waste batteries of different sizes.

[0038] In practical applications, the inner surfaces of the push plate 153 and the clamp side baffle 154 are provided with anti-slip rubber plates 155 to firmly clamp the battery 160 and prevent the battery 160 from shifting during the cutting process, thus affecting the cutting accuracy of the battery 160.

[0039] Please see Figure 5As shown, the feeding assembly 110 includes a feeding cylinder 111 located above the feeding assembly 120, a feeding push plate 112 connected to the feeding cylinder 111, and a baffle bracket 113 located on the side of the feeding cylinder 111. The feeding cylinder 111 is vertically arranged with the feeding assembly 120, and the feeding push plate 112 is located below the feeding cylinder 111 to push the battery 160 for feeding. The baffle bracket 113 and the feeding push plate 112 are located on the same side of the feeding assembly 120. The baffle bracket 113 is perpendicular to the feeding assembly 120 and the feeding cylinder 111 to prevent the battery 160 from falling during the feeding process. In practical applications, the feeding cylinder 111 can drive the feeding push plate 112 to move perpendicularly to the feeding assembly 120, pushing the battery 160 into the battery clamp 150 on the feeding assembly 120. It should be noted that in this cutting device, the loading assembly 110 is generally used in conjunction with an existing conveying device. The conveying device and the feeding assembly 120 are parallel and close together. The loading assembly 110 is fixed to a steel frame. By adjusting the height of the steel frame, the loading push plate 112 in the loading assembly 110 is positioned above the platforms of the conveying device and the feeding assembly 120. When the battery 160 is placed on the conveying device (e.g., a conveyor belt), the conveying device transports the battery 160 to a position where it is aligned with the push plate 153 and the side baffle 154 of the battery clamp 150. At this point, the loading cylinder 111 of the loading assembly 110 drives the loading push plate 112 to move perpendicularly to the feeding assembly 120. The loading push plate 112 pushes the battery 160 from the conveying device into the battery clamp 150 of the feeding assembly 120, completing the loading process. Additionally, in Figure 1 To show the overall structure of the cutting device, the steel frame and conveying device are omitted from the display to avoid obscuring other components.

[0040] In addition, when the cutting device is actually used, the support 121 of the feed assembly 120, the mounting base 141 of the sawing unit, and the bottom of the stop bracket 113 are all fixed on the frame, and the positions of each component follow the above-mentioned positional relationship.

[0041] The precision adaptive cutting device 100 for batteries of different sizes also includes a battery limiting seat 170. The battery limiting seat 170 and the baffle bracket 113 are respectively disposed on both sides of the feeding assembly 120 to limit the battery 160 within the battery clamp 150 when the feeding assembly 110 feeds the battery 160. In practice, the battery limiting seat 170 can be fixed to a steel frame, perpendicular to the feeding direction of the feeding assembly 110, to prevent the feeding assembly 110 from pushing the battery 160 out of the battery clamp 150.

[0042] In some other embodiments, two ranging sensors 131 are respectively disposed on the stop bracket 113 and the ranging sensor 131 on both sides of the feed assembly 120.

[0043] Those skilled in the art should know that the linear modules (including the first linear module 142 and the second linear module 122) used in this utility model are all commonly used linear modules in the prior art that have sliders and can realize linear motion. The cylinders used in this device (including the feeding cylinder 111 and the dual-axis cylinder 152) are all metal parts in the prior art that can perform linear reciprocating motion.

[0044] The working principle of this utility model is as follows:

[0045] The present invention provides a precision adaptive cutting device 100 for batteries of different sizes, which includes a feeding component 110, a feeding component 120, a sensing component 130, a sawing component 140, and a control system connecting the sensing component 130 and the sawing component 140. The feeding component 120 is also provided with a battery clamp 150 suitable for different battery sizes 160. In application, the cutting device uses a feeding assembly 110 to feed waste batteries 160 to be cut into a battery clamp 150 on a feeding assembly 120. The battery clamp 150 firmly holds the battery 160 and moves towards the sawing assembly 140 under the push of the feeding assembly 120. Simultaneously, a sensing assembly 130 measures the distance between itself and the two ends of the battery 160 it passes and feeds the data back to the control system. The control system calculates the actual size and relative position of the battery 160 and then adjusts the cutting parameters of the sawing assembly 140. This includes controlling the movement of the first linear module 142 via a servo feed motor 146 and adjusting the position of the saw blade 145 relative to the cutting motor 144 via a position adjustment assembly 147. This allows the saw blade 145 to adapt to the battery size and precisely cut the battery 160. This invention's precise adaptive cutting device 100 for batteries of different sizes eliminates the need for frequent component replacements for batteries of different sizes or models, has a high degree of automation, improves battery cutting efficiency, and thus increases the resource recycling rate of waste lithium batteries.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
