Description

Technical Field

[0001] This invention relates to the field of lithium battery recycling technology, specifically to a device for separating the positive and negative electrodes of lithium batteries based on X-rays. Background Technology

[0002] As the core components of lithium batteries, the positive and negative electrode sheets contain precious metals such as cobalt, lithium, and nickel, as well as non-ferrous metals such as copper and aluminum. Achieving efficient separation of the positive and negative electrode sheets is a key step in improving the purity of lithium battery recycling and reducing recycling costs. Currently, existing separation methods mainly include physical separation and chemical separation. Among them, physical separation is widely used in industrial production due to its advantages such as no secondary pollution and convenient operation.

[0003] However, existing physical separation equipment still has certain shortcomings in practical applications. On the one hand, traditional separation equipment mostly uses screening and air classification, which are limited by factors such as differences in electrode size and surface impurities, resulting in low separation accuracy and easy mixing of positive and negative electrodes, affecting the quality of subsequent recycling. On the other hand, some separation equipment lacks an effective material pretreatment mechanism, and mixed electrodes are easily stacked and transported, which not only reduces separation efficiency but also aggravates equipment wear. At the same time, the detection and sorting components of existing equipment are mostly single-set, and their performance is prone to degradation after long-term continuous operation, shortening the service life of the equipment. In addition, some equipment has poor adaptability, making it difficult to meet the separation needs of electrodes of different sizes and thicknesses, and the separation angle cannot be flexibly adjusted, further limiting the improvement of separation effect.

[0004] In view of this, we propose a device for separating the positive and negative electrodes of lithium batteries based on X-rays. Summary of the Invention

[0005] The purpose of this invention is to provide a device for separating the positive and negative electrodes of a lithium battery based on X-rays, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An apparatus for separating positive and negative electrode sheets of lithium batteries based on X-rays includes a body and a support. The body is provided with a conveying mechanism for conveying the dispersed positive and negative electrode sheets of lithium batteries. A separation chamber is provided on one side of the body at the end of the conveying mechanism. A separation assembly is provided on the body.

[0007] In a further embodiment, the X-ray tube transmitter and the X-ray receiver and signal processing unit are configured in two sets to improve separation efficiency.

[0008] In a further embodiment, the nozzles are arranged in multiple sets, and the multiple sets of nozzles are arranged in a linear array with equal spacing.

[0009] In a further embodiment, the support is provided with a feeding assembly, which includes a feeding rack. Both the feeding rack and the top of the support are fixedly installed with limit posts. Multiple sets of limit posts are provided. Vibration springs are fixedly installed on the outside of two adjacent sets of limit posts in the vertical direction. A vibration motor fixing end is fixedly installed on the feeding rack.

[0010] In a further embodiment, a protrusion is fixedly installed on the outside of the feed rack, and a rotating rod is fixedly installed inside the protrusion by fasteners. An inclined plate is fixedly installed on the rotating rod. Two sets of the protrusion, rotating rod and inclined plate are provided, and the two sets of the protrusion, rotating rod and inclined plate are mirrored on both sides of the output end of the feed rack to better guide the material.

[0011] In a further embodiment, the fastener includes a nut and a washer to adjust the orientation of the ramp.

[0012] In a further embodiment, a movable component is provided outside the separation chamber. The movable component includes an auxiliary frame, which is fixedly installed on the feed rack. An auxiliary hydraulic cylinder is fixedly installed at the top of the auxiliary frame. The bottom of the piston end of the auxiliary hydraulic cylinder is fixedly connected to the center of the top of a rectangular plate. Multiple sets of limiting rods are fixedly installed at the top of the rectangular plate, and the limiting rods are slidably installed inside the auxiliary frame.

[0013] In a further embodiment, a fixed frame is fixedly installed at the top of the machine body, an asynchronous motor is fixedly installed at the center of the top of the fixed frame, a rotating shaft is fixedly installed at the output end of the asynchronous motor, and a baffle is fixedly installed on the rotating shaft. The baffle is arranged in three sets, and the three sets of baffles are arranged in a circumferential array with equal spacing to better divert materials.

[0014] In a further embodiment, a plurality of spring rods are fixedly connected to one end of the end of the baffle away from the rotating shaft, and a slider is fixedly installed on the other end of the spring rod. The slider is slidably installed inside the baffle and slides against the side wall of the machine body.

[0015] In a further embodiment, a cleaning assembly is provided on the fixed frame. The cleaning assembly includes a rectangular frame, which is fixedly installed on the fixed frame. Multiple sets of screws are threaded inside the rectangular frame. The bottom end of the screws is rotatably installed inside a movable frame. An electrostatic cleaning roller is rotatably installed inside the movable frame via bearing components to clean the electrode sheets.

[0016] Compared with the prior art, the present invention provides a device for separating the positive and negative electrodes of lithium batteries based on X-rays, which has the following beneficial effects: 1. This X-ray separation device for lithium battery positive and negative electrode sheets utilizes a separation component and a conveyor mechanism on the machine body to transport the dispersed electrode sheets into the X-ray detection and sorting chamber via a conveyor belt. The X-ray tube emits X-rays continuously onto the conveyor surface. After the X-rays irradiate the electrode sheets, they are received by the X-ray receiver and signal processing unit. The X-ray receiver and signal processing unit captures the different X-ray imaging signals of the two types of electrode sheets and transmits these signals to the controller in real time. The controller converts the judgment result into an electrical signal and transmits it to the corresponding nozzle, controlling the nozzle's spray timing and duration to achieve physical separation of the two types of electrode sheets. The device also uses an arc plate and a guide plate to block and guide the separated electrode sheets. When the hydraulic cylinder is activated, the hinged frame causes the air distribution box to swing, thereby adjusting the nozzle orientation and further improving separation.

[0017] 2. This X-ray separation equipment for lithium battery positive and negative electrode sheets improves production efficiency by setting up a feeding component to pour the mixed positive and negative electrode sheets into the feeding rack. The vibration motor is started in advance, and the feeding rack vibrates in conjunction with the limit post and vibration spring, so that the material is continuously conveyed to the conveying mechanism. With the help of two sets of protrusions, rotating rods and inclined plates, it can accommodate more sizes of materials in the current batch. The two sets of inclined plates can guide the material to be conveyed one by one, so that the electrode sheets are distributed in a single layer and uniformly on the conveyor belt, thereby improving production efficiency.

[0018] 3. To improve the practicality of this X-ray separation device for lithium battery positive and negative electrode sheets, a moving component is incorporated. When the auxiliary hydraulic cylinder on the auxiliary frame is activated, the rectangular plate moves up and down under the limit of the limit rod, thereby servo-controlling the quantity and rate of material output from the feeding rack. When the asynchronous motor on the fixed frame is activated, the rotating shaft drives the baffle to rotate, and the slider squeezes the machine body, causing the spring rod to compress and deform, thus separating the positive and negative electrode sheets of the battery. For example, when the rotating shaft rotates forward, the electrode sheets between two adjacent sets of baffles move towards the conveyor belt in the conveying mechanism and are subsequently identified and separated by X-rays on the same side. Conversely, when the rotating shaft rotates backward, the electrode sheets between two adjacent sets of baffles move towards the other side of the conveyor belt in the conveying mechanism and are subsequently identified and separated by X-rays on the same side. This alternating conveying ensures that one side of the X-ray identification component is always idle, thus improving its service life.

[0019] 4. In order to improve the separation efficiency, this X-ray-based equipment for separating positive and negative electrode sheets of lithium batteries is equipped with a cleaning component. By synchronously rotating a screw inside a rectangular frame, the moving frame can move up and down, thereby causing the electrostatic cleaning roller to move synchronously to accommodate positive and negative electrode sheets of varying thicknesses. When the positive and negative electrode sheets come into contact with the electrostatic cleaning roller, the latter rotates, thereby electrostatically adsorbing dust and improving the separation efficiency.

[0027] In one embodiment of the present invention, a moving component 7 is provided outside the separation chamber 4.

[0028] In one embodiment of the present invention, a cleaning component 8 is provided on the fixed frame 75. The cleaning component 8 includes a rectangular frame 81, which is fixedly installed on the fixed frame 75. Two sets of screws 82 are threadedly fitted inside the rectangular frame 81. The bottom ends of the screws 82 are rotatably installed inside the movable frame 83. An electrostatic cleaning roller 84 is rotatably installed inside the movable frame 83 through a bearing component to clean the electrode sheet.

[0029] Working principle: First, the feeding component 6 is started, and the mixed lithium battery positive and negative electrode sheets are poured into the feeding rack 61. The vibration motor 64 is started in advance, and the vibration motor 64 drives the feeding rack 61 to vibrate. The limiting post 62 limits the feeding rack 61. The vibration spring 63, together with the vibration motor 64, amplifies the vibration effect, so that the material in the feeding rack 61 is continuously conveyed to the conveying mechanism 3. When the moving component 7 is started, the auxiliary hydraulic cylinder 72 on the auxiliary frame 71 works. Under the limiting action of the limiting rod 74, it drives the rectangular plate 73 to move up and down. The quantity and rate of material output by the feeding rack 61 are adjusted by servo control to ensure that the electrode sheets on the conveying mechanism 3 are evenly distributed. The angle of the inclined plate 67 is adjusted by the protrusion 65 and the rotating rod 66. The two sets of mirrored inclined plates 67 guide the material, so that the electrode sheets are distributed in a single layer and evenly on the conveyor belt of the conveying mechanism 3, avoiding the stacking of electrode sheets from affecting the subsequent detection and separation effect.

[0030] When the asynchronous motor 76 on the fixed frame 75 is started, the asynchronous motor 76 drives the rotating shaft 77 to rotate, which in turn drives the three sets of equally spaced circular array baffles 78 to rotate. The sliders 710 on the baffles 78 slide against the side wall of the machine body 1, and the spring rods 79 play a buffering role. When the rotating shaft 77 rotates forward, the electrode plates intercepted between two adjacent sets of baffles 78 move to one side of the conveyor belt of the conveyor mechanism 3, and are detected and separated by the X-ray recognition component on that side. When the rotating shaft 77 rotates in reverse, the electrode plates move to the other side of the conveyor belt and are processed by the X-ray recognition component on the other side. Through alternating conveying, the X-ray recognition components on both sides can alternately stop and rest, extend the service life of the components, and improve the practicality of the equipment.

[0031] The two sets of screws 82 inside the rectangular frame 81 are rotated synchronously in advance, which drives the moving frame 83 to move up and down, thereby adjusting the height of the electrostatic cleaning roller 84 to accommodate battery positive and negative electrode sheets of different thicknesses. When the electrode sheet passes through the electrostatic cleaning roller 84 with the conveying mechanism 3, the electrode sheet contacts the electrostatic cleaning roller 84 and drives it to rotate. The electrostatic cleaning roller 84 removes dust from the surface of the electrode sheet through electrostatic adsorption, improving the subsequent separation efficiency.

[0032] The electrode sheet enters the X-ray detection and sorting chamber 51 of the separation component 5 along with the conveying mechanism 3. The X-ray tube emitting end 53 is activated and continuously emits X-rays towards the conveying surface. After the X-rays irradiate the electrode sheet, they are received by the X-ray receiving and signal processing end 54. Due to the different material density and composition of the positive electrode sheet (aluminum foil + positive active material) and the negative electrode sheet (copper foil + negative active material), there is a significant difference in their ability to reflect X-rays. The X-ray receiving and signal processing end 54 captures the different X-ray imaging signals of the two types of electrodes and transmits the signals to the controller 52 in real time. The image processing module of the controller 52 performs rapid analysis, identification and judgment on the X-ray imaging signals, accurately distinguishes the positive electrode sheet and the negative electrode sheet on the conveyor belt, and converts the judgment result into an electrical signal and transmits it to the corresponding nozzle 510 to control the jetting timing and jetting duration of the nozzle 510. The determined positive / negative electrode sheets move to the sorting area at the end of the conveyor belt of the conveyor mechanism 3. If it is the target electrode sheet (such as a positive electrode sheet), the controller 52 triggers the high-pressure air pump 55 to work. The high-pressure gas enters the air distribution box 58 through the air pipe 56 and the connector 59, and then sprays out high-pressure airflow through multiple sets of equally spaced linear array nozzles 510, blowing the electrode sheet off the conveyor belt. If it is another type of electrode sheet (such as a negative electrode sheet), the nozzles 510 do not move, and the electrode sheet slides off the conveyor belt naturally, realizing the physical separation of the two types of electrode sheets. The arc plate 512 inside the separation chamber 4 plays a blocking role for the blown-off electrode sheet, and the guide plate 513 guides the electrode sheet to fall in an orderly manner to prevent the electrode sheet from scattering. If it is necessary to adjust the separation angle, the adjusting hydraulic cylinder 511 is activated. The adjusting hydraulic cylinder 511 drives the hinge frame 57 to swing, which in turn drives the air distribution box 58 to rotate, adjusting the orientation of the nozzles 510 to further improve the separation effect.

[0033] All electrical components mentioned in this application are electrically connected to the controller 52 and the 220V mains power. The controller 52 is a conventional and known device that controls the conveying mechanism 3, the X-ray detection and sorting chamber 51, the X-ray tube transmitter 53, the X-ray receiver and signal processing terminal 54, the high-pressure air pump 55, the connector 59, the nozzle 510, the regulating hydraulic cylinder 511, the vibration motor 64, the auxiliary hydraulic cylinder 72, the asynchronous motor 76, and the electrostatic cleaning roller 84. The signal interaction of each component adopts the PLC control protocol commonly used in industrial equipment, which is common knowledge to those skilled in the art and can be implemented without additional detailed description. The control logic and signal interaction method are existing technologies and will not be described in detail. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The standard parts all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.
