Description
Technical Field
[0001] This invention provides a visual sorting device for recycling waste lithium batteries, specifically relating to the technical field of waste battery sorting equipment. Background Technology
[0002] Waste lithium batteries are rich in precious metals such as lithium, cobalt, and nickel, and contain a variety of harmful substances. Scientific and reasonable sorting and recycling can not only realize resource recycling and create considerable economic benefits, but also avoid environmental pollution, which is of great significance to the sustainable development of the new energy industry.
[0003] In the existing technology, the invention patent with authorization announcement number CN119771794B discloses an automatic sorting and recycling device for waste new energy batteries. It realizes the intermittent conveying of batteries through an inclined detection table, a limit rod, and a transmission component. It relies on a vision camera to identify the code on the surface of the battery, and then the processor controls the rotating component to drive the sorting table to rotate, thus completing the battery sorting and recycling.
[0004] However, the device has obvious drawbacks: the batteries remain stationary on the inspection platform, lacking a dedicated structure to adjust the battery's posture, and rely on the batteries' gravity to roll down for transport, which cannot avoid offset and stacking during the transport process. If the surface coding or identification features of the waste batteries are obscured due to stacking, the vision camera cannot fully collect information, which can easily lead to sorting misjudgments. It is difficult to achieve stable sorting of waste batteries, affecting sorting efficiency and accuracy, and further improvements are needed. Summary of the Invention

It aims to solve the technical problems mentioned in the background technology, namely, that "in existing waste lithium battery sorting devices, batteries are prone to stacking and shifting during transportation, and misjudgment occurs during identification due to surface coding or feature occlusion caused by the static state. Furthermore, the coordination between the transportation, identification, and sorting mechanisms is insufficient, and there is a lack of targeted posture adjustment structures, resulting in low sorting efficiency and accuracy."

[0029] By using a receiving motor and gearbox to drive the tray to rotate precisely, combined with the funnel-shaped inlet of the receiving chamber and the full-material alarm design, the problem of inaccurate sorting and positioning and the need for frequent manual cleaning in traditional receiving mechanisms is solved. This enables automatic classification and collection of batteries after sorting and full-material reminders, reducing manual intervention costs and improving sorting efficiency.

[0047] The present invention will be further described below with reference to embodiments.
[0048] As a first embodiment of this application:
[0049] Reference Appendix Figures 1 to 7 As shown, a visual sorting device for recycling waste lithium batteries includes a support frame 1. A control unit 11 is fixedly installed on one side of the outer wall of the support frame 1 by bolts, and a portal frame 12 is fixedly installed on the top side by welding. A recognition camera group 13 is fixedly installed on the portal frame 12 by fasteners.
[0050] Specifically, the support frame 1 is also equipped with a collaborative feeding mechanism 2;
[0051] The collaborative feeding mechanism 2 is located between the feeding end of the support frame 1 and the recognition camera group 13, and is used to transport the waste lithium batteries one by one to the detection area of the recognition camera group 13.
[0052] It includes a material dropping component 21 and a conveying component 22. The material dropping component 21 is fixedly mounted on the side of the support frame 1 away from the recognition camera group 13 by bolts. The conveying component 22 is arranged along the length of the support frame 1, and the feeding end of the conveying component 22 corresponds vertically to the discharging end of the material dropping component 21. The discharging end of the conveying component 22 extends to the top of the receiving mechanism 4.
[0053] Specifically, the material feeding assembly 21 consists of a feeding hopper 211, feeding channels 212, a material distribution component 213, an infrared detector 214, a material distribution motor 215, and a first pulley structure 216. The feeding hopper 211 is welded and fixed to the support frame 1. It has three integrally formed feeding channels 212 inside. Each feeding channel 212 has a material distribution component 213 rotatably mounted in it via bearings. The three material distribution components 213 are synchronously driven by the first pulley structure 216. A transparent window is opened at the bottom of the feeding hopper 211 at a position corresponding to the material distribution component 213. An infrared detector 214 is embedded and fixed in the transparent window. The material distribution motor 215 is mounted on the outer wall of the feeding hopper 211 via a motor mount. Its output shaft is connected to the active synchronous pulley in the first pulley structure 216 via a key. The material distribution motor 215 is also electrically connected to the control unit 11.
[0054] Furthermore, the infrared detector 214 monitors the position of the V-groove support block 222 in the lower conveying assembly 22 in real time. When an empty V-groove support block 222 is detected to move directly below the material drop channel 212, the infrared detector 214 sends a trigger signal to the control unit 11. The control unit 11 then controls the material distribution motor 215 to start, which drives the three material distribution components 213 to rotate synchronously at a fixed angle through the first pulley structure 216. This ensures that the single waste lithium battery contained between the adjacent material distribution plates of each material distribution component 213 falls precisely into the corresponding V-groove support block 222. This method, through "detection, triggering, and material distribution", avoids the stacking problem caused by multiple batteries falling at the same time, ensuring the accuracy of subsequent identification.
[0055] Specifically, the material distribution component 213 includes a central shaft and material distribution plates uniformly welded and fixed to the outer circumference of the shaft. A receiving space for accommodating a single waste lithium battery is formed between two adjacent material distribution plates. The first pulley structure 216 consists of four synchronous pulleys and a synchronous belt. Two synchronous pulleys are fixed to the shaft end of the central material distribution component 213 by a key. The shaft ends of the other two material distribution components 213 are each fixed to a synchronous pulley by a key. Adjacent synchronous pulleys are connected by a synchronous belt drive to ensure that the three material distribution components 213 rotate at the same speed and have a synchronized material distribution rhythm.
[0056] Specifically, the conveying assembly 22 includes an electric conveyor belt 221 and a V-groove support block 222. The electric conveyor belt 221 is mounted on the support frame 1 by a bracket. The V-groove support block 222 is fixed to the conveying surface of the electric conveyor belt 221 by bolts at intervals. The V-groove of the V-groove support block 222 is adapted to the cylindrical shape of the waste lithium battery, which can prevent the battery from shifting during the conveying process.
[0057] Furthermore, an infrared sensor is mounted on the support frame 1 at a position corresponding to the recognition camera group 13 via a bracket. The infrared sensor is electrically connected to the control unit 11. When the infrared sensor detects that the V-slot support block 222 carrying the waste lithium battery has moved to the detection area directly below the recognition camera group 13, it immediately sends a pause signal to the control unit 11. The control unit 11 controls the electric conveyor belt 221 to stop running, ensuring that the battery is in a stationary state when the recognition camera group 13 takes pictures, thereby improving the recognition accuracy. After the recognition is completed, the control unit 11 controls the electric conveyor belt 221 to resume running and transport the battery to the receiving mechanism 4.
[0058] As a second embodiment of this application:
[0059] Reference Appendix Figure 1 , Figures 8 to 9 As shown, in the above-mentioned waste lithium battery recycling visual sorting device, the collaborative transfer mechanism 3 is located below the recognition camera group 13 and is used to drive the waste lithium batteries in the detection area to rotate so that the recognition camera group 13 can fully recognize them. It includes a concave plate 31, a transfer motor 32, a first gear 33, a rotating shaft 34, a second gear 35, a transfer wheel 36, and a second pulley structure 37.
[0060] The concave plate 31 is fixed to the support frame 1 by bolts. The top of the concave plate 31 is fixedly mounted with a material transfer motor 32 by a motor base. The output shaft end of the material transfer motor 32 is fixed with a first gear 33 by a key. A rotating shaft 34 is rotatably connected to the concave plate 31 by bearings. A second gear 35 is fixed to the rotating shaft 34 by a key. The second gear 35 meshes with the first gear 33 for transmission. The two sides of the lower end of the concave plate 31 are symmetrically connected to the material transfer wheels 36 by bearings. The two ends of the rotating shaft 34 are respectively connected to the two material transfer wheels 36 by a second pulley structure 37. The material transfer motor 32 is electrically connected to the control unit 11.
[0061] Specifically, the second pulley structure 37 includes two synchronous pulleys and a synchronous belt. One synchronous pulley is fixed to the rotating shaft 34 by a key, and the other synchronous pulley is fixed to the rotating shaft of the transfer wheel 36 by a key. The two synchronous pulleys are connected by a synchronous belt. Several rubber protrusions for increasing friction are integrally formed on the outer circumferential surface of the transfer wheel 36, and the two transfer wheels 36 respectively contact the bottom of both ends of the waste lithium battery.
[0062] In other words, when the electric conveyor belt 221 is paused and the waste lithium battery is in the detection area, the control unit 11 synchronously starts the transfer motor 32. The transfer motor 32 drives the rotating shaft 34 to rotate through the meshing transmission of the first gear 33 and the second gear 35. The rotating shaft 34 then drives the two transfer wheels 36 to rotate synchronously and in the same direction through the second pulley structure 37 on both sides. The transfer wheels 36 drive the waste lithium battery to rotate slowly around its own axis through the friction between the outer rubber protrusion and the end of the battery. During this process, the identification camera group 13 continuously captures and collects information on the surface of the battery to ensure that the identification features such as labels and codes on the surface of the battery are not obstructed, thus completely solving the problem of identification failure caused by feature occlusion in traditional static identification.
[0063] Furthermore, the rotation speed of the transfer motor 32 can be adjusted by the control unit 11 to adapt to the rotation requirements of waste lithium batteries of different diameters, and the installation height of the transfer wheel 36 can be finely adjusted by the shims to ensure effective contact with the battery end.
[0064] As a third embodiment of this application:
[0065] like Figure 1 , Figure 10 , Figure 11 As shown, in the above-mentioned waste lithium battery recycling visual sorting device, the receiving mechanism 4 is located below the feeding end of the collaborative feeding mechanism 2, and is used to receive the waste lithium batteries after identification and sorting.
[0066] It includes a receiving motor 41, a gearbox 42, a tray 43, and a receiving chamber 45. The tray 43 is horizontally positioned below the feeding end of the collaborative feeding mechanism 2, and an annular placement area 44 is provided on the tray 43. The receiving chamber 45 is detachably placed in the placement area 44. The output end of the gearbox 42 is fixedly connected to the center of the tray 43 by a key, which is used to drive the tray 43 to rotate stably.
[0067] The receiving motor 41 is electrically connected to the control unit 11. After receiving the recognition signal from the recognition camera group 13, it drives the tray 43 to rotate to the corresponding receiving chamber 45, which is aligned with the feeding end of the collaborative feeding mechanism 2.
[0068] Specifically, there are three receiving chambers 45, which are evenly distributed around the circumference of the tray 43 in the placement area 44. Each receiving chamber 45 has a horn-shaped inlet on its top to facilitate the falling of batteries. The gearbox 42 is fixedly installed on the support frame 1 by a bracket. Its input end is connected to the output shaft of the receiving motor 41 by a coupling, and its output end is fixedly connected to the center of the tray 43. The gearbox 42 can reduce the output speed of the receiving motor 41 and increase the torque to ensure the accuracy of the rotation angle of the tray 43.
[0069] In other words, after the identification camera group 13 completes the identification, it sends the identification signals such as the type and specifications of the battery to the control unit 11. The control unit 11 calculates the position of the corresponding receiving compartment 45 according to the preset sorting rules, and then controls the receiving motor 41 to start. The transmission 42 drives the tray 43 to rotate at a fixed angle, so that the target receiving compartment 45 is accurately moved to the direct line of the electric conveyor belt 221. At the same time, the electric conveyor belt 221 resumes operation and transports the identified waste lithium batteries to the delivery end. The batteries fall into the corresponding receiving compartment 45 under their own gravity, realizing automatic sorting and collection.
[0070] Furthermore, an infrared full-load sensor is embedded and fixed on the upper part of the inner wall of each receiving chamber 45. The infrared full-load sensor is electrically connected to the control unit 11. When the waste lithium batteries in the receiving chamber 45 accumulate to a preset height, the infrared full-load sensor sends a full-load signal to the control unit 11. The control unit 11 can trigger an alarm prompt so that the waste batteries can be sent to the subsequent processing stage.
[0071] The complete working and usage principle of the above embodiments is as follows:
[0072] First, the messy used lithium batteries are poured into the discharge hopper 211, where they naturally disperse into the three discharge channels 212. An infrared detector 214 at the bottom of the discharge hopper 211 monitors the V-groove supports 222 on the conveyor belt 221 below in real time. When an empty V-groove support 222 is detected moving directly below the discharge channel 212, a trigger signal is immediately sent to the control unit 11. The control unit 11 then starts the dispensing motor 215, which, through the first pulley structure 216, drives the dispensing components 213 in the three discharge channels 212 to rotate synchronously at a fixed angle. This ensures that the individual batteries contained in the gaps between the dispensing plates of each dispensing component 213 fall precisely into the corresponding V-groove support 222, preventing battery stacking.
[0073] When the V-groove support block 222 carrying the battery moves to the detection area directly below the recognition camera group 13, the infrared sensor on the support frame 1 sends a signal to the control unit 11, triggering the electric conveyor belt 221 to stop. At the same time, the control unit 11 starts the transfer motor 32 of the cooperative transfer mechanism 3. The transfer motor 32 drives the rotating shaft 34 to rotate through the meshing of the first gear 33 and the second gear 35. The rotating shaft 34 drives the two transfer wheels 36 to rotate synchronously and in the same direction through the second pulley structure 37 on both sides. The transfer wheels 36 use the friction between the outer rubber protrusions and the end of the battery to drive the battery to rotate slowly around its own axis. The recognition camera group 13 continuously captures and collects complete information of the battery surface, eliminating recognition blind spots.
[0074] After identification, the identification camera group 13 transmits signals such as battery type and specifications to the control unit 11. The control unit 11 calculates the position of the target receiving compartment 45 according to the preset sorting rules, starts the receiving motor 41, and drives the tray 43 to rotate precisely through the gearbox 42, so that the corresponding receiving compartment 45 is aligned with the delivery end of the electric conveyor belt 221. Then the electric conveyor belt 221 resumes operation, and the batteries fall into the compartment through the horn-shaped inlet at the top of the receiving compartment 45, realizing automatic sorting and collection. When the batteries in the receiving compartment 45 accumulate to a preset height, the infrared full-material sensor on the inner wall sends a full-material signal, and the control unit 11 triggers an alarm, prompting the staff to move the batteries and ensuring the continuous operation of the device.
