Description

Technical Field

[0001] This utility model relates to the field of lithium battery sorting technology, specifically a laser identification lithium battery sorting device. Background Technology

[0002] By equipping a high-power laser emitter and a high-sensitivity laser receiver, when the lithium battery moves at a constant speed on the conveyor belt, the laser beam emitted by the laser emitter quickly scans the surface of the battery. When the laser beam comes into contact with the surface of the battery, it will produce phenomena such as reflection and scattering. The receiver accurately captures these feedback signals. By analyzing the changes in the intensity, phase, reflection angle and other characteristics of the laser signal, the receiver obtains key information such as the size, shape and surface texture of the battery, and converts it into digital signals and transmits them to the control system, thereby realizing the sorting of lithium batteries.

[0003] While laser identification of lithium batteries using a laser emitter is simple to operate and highly efficient, it is prone to laser scattering due to impurities such as dust and moisture in the environment, which can cause laser signal attenuation or distortion, thus affecting the accuracy of lithium battery identification.

[0004] Therefore, there is an urgent need for a laser-based lithium battery sorting device to solve the above problems. Utility Model Content

A hot air blower is provided on the side of the L-shaped plate away from the identification frame. The air outlet of the hot air blower is connected to the other of the two fixed pipes.

[0009] The conveyor belt is provided with a limiting component for limiting the lithium battery body. The limiting component includes multiple limiting frames detachably disposed on the side wall of the conveyor belt. Each limiting frame is fixedly connected to a limiting cover on the side away from the conveyor belt. The limiting cover is conical. The identification frame is provided with a rotating component for rotating the lithium battery body.

[0010] The end of each of the limiting covers that is furthest from the limiting frame is lower than the highest sidewall of the lithium battery body.

[0011] The rotating assembly includes mounting brackets fixedly connected to the side walls of the identification frame near both ends of the lithium battery body. Two mounting brackets are rotatably connected to rubber wheels. A motor for driving the rubber wheels to rotate is provided on the side of the two mounting brackets that are far apart from each other.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-4 The figure shows a laser identification lithium battery sorting device, which includes a lithium battery body 101 and a conveyor belt 102. A robot 103 is provided on one side of the conveyor belt 102. The device also includes an identification component provided on the robot 103 for laser identification of the lithium battery body 101 and a cleaning component provided on the identification component for removing dust, moisture and other impurities during the identification process of the lithium battery body 101.

[0023] The recognition component includes a recognition frame 201 fixedly connected to the operating end of the robotic arm of robot 103, and a laser generator 202 is provided on the bottom wall of the inner wall of the recognition frame 201.

[0024] The cleaning component includes two U-shaped tubes 301 fixedly connected to the two opposite side walls of the identification frame 201. The four U-shaped tubes 301 are connected to the interior of the identification frame 201 through multiple connecting tubes. The two U-shaped tubes 301 located on the same side are connected by a fixing tube 302. A collection box 303 is fixedly connected to the side of the identification frame 201 away from the conveyor belt 102. A fan 304 is provided on one side of the collection box 303. The air inlet of the collection box 303 is connected to one of the two fixing tubes 302 through an installation tube 305.

[0025] It should be noted that the identification component enables precise sorting of lithium batteries, thereby effectively improving product quality and production efficiency. Simultaneously, the cleaning component isolates the lithium battery body 101 from the external environment and removes dust, moisture, and other impurities from the detection environment, reducing the risk of laser scattering and thus decreasing the likelihood of laser signal attenuation or distortion, thereby improving the accuracy of lithium battery identification.

[0026] It is worth noting that sorting mechanisms typically employ high-speed pneumatic push rods, robotic arms, or electromagnetic sorting devices. For example, when a defective battery is detected, the robotic arm picks up the lithium battery from the conveyor belt 102 and moves it to the defective product collection area. For qualified lithium batteries, they are allowed to continue to be transported on the conveyor belt 102 to the qualified product collection area. As this is existing technology, it is not illustrated here.

[0027] It should be emphasized that this application is aimed at laser identification and sorting of cylindrical lithium batteries. For lithium batteries of other shapes, laser identification and sorting can be achieved through improvements to the limiting components, which will not be elaborated here.

[0028] Please see Figure 3 In the figure, an L-shaped plate 306 is fixedly connected to the side of the identification frame 201 away from the mounting pipe 305. A hot air blower 307 is provided on the side of the L-shaped plate 306 away from the identification frame 201. The air outlet of the hot air blower 307 is connected to the other of the two fixed pipes 302.

[0029] It should be noted here that the hot air blower 307 is used to dry the moisture in the environment of the lithium battery body 101.

[0030] Please see Figure 4 The conveyor belt 102 shown in the figure is provided with a limiting component for limiting the lithium battery body 101. The limiting component includes multiple limiting frames 401 detachably disposed on the side wall of the conveyor belt 102. Each limiting frame 401 is fixedly connected to a limiting cover 402 on the side away from the conveyor belt 102. The limiting cover 402 is cone-shaped. The identification frame 201 is provided with a rotating component for rotating the lithium battery body 101.

[0031] It should be noted here that the setting of the limiting component is used to improve the stability of the lithium battery body 101 during the identification and sorting process;

[0032] It is worth noting that the limiting component is detachably mounted on the conveyor belt 102, which facilitates the appropriate replacement of lithium battery models as needed for identification and sorting.

[0033] Please see Figure 4 In the diagram, the end of each limiting cover 402 that is away from the limiting frame 401 is lower than the highest side wall of the lithium battery body 101.

[0034] It should be noted here that by setting the end of the limiting cover 402 away from the limiting frame 401 to be lower than the highest side wall of the lithium battery body 101, it is easier for the robotic arm to grab the lithium battery body 101 after it has been identified, thereby completing the sorting operation.

[0035] Working principle: When performing laser identification and sorting on the lithium battery body 101, the lithium battery body 101 is first placed inside the limiting cover 402 on the side wall of the conveyor belt 102. The conical inner wall of the limiting cover 402 is used to limit the lithium battery body 101. After the lithium battery body 101 is limited, the lithium battery body 101 can be moved to the robot 103 by the conveyor belt 102.

[0036] When the lithium battery body 101 moves to the robot 103, the rotation of the conveyor belt 102 is stopped. At this time, the robot 103 is started, and the recognition frame 201 moves closer to the limiting cover 402. When one end of the recognition frame 201 abuts against the end face of the limiting cover 402, the movement of the robot 103 is stopped. At this time, the lithium battery body 101 is isolated from the external environment. Then, the rotating component drives the lithium battery body 101 to rotate. At the same time, the exhaust fan 304 is started to absorb dust and other impurities in the environment of the lithium battery body 101 into the collection box 303. At the same time, the hot air fan 307 is started to dry the moisture in the environment of the lithium battery body 101. This removes dust, moisture and other impurities in the detection environment of the lithium battery body 101, reduces the risk of laser scattering, and reduces the probability of laser signal attenuation or distortion, thereby improving the recognition accuracy of the lithium battery.

[0037] After removing dust, moisture, and other impurities from the detection environment at the lithium battery body 101, the laser generator 202 can be activated. The emitted laser beam quickly scans the surface of the lithium battery body 101. When the laser beam contacts the surface of the lithium battery body 101, it will produce phenomena such as reflection and scattering. The receiver accurately captures these feedback signals. By analyzing the changes in the intensity, phase, reflection angle, and other characteristics of the laser signal, the receiver obtains key information such as the size, shape, and surface texture of the battery and converts it into digital signals for transmission to the control system.

[0038] The control system uses advanced image recognition algorithms and machine learning models to perform in-depth analysis and processing of the collected laser data. Based on preset lithium battery standard parameters and feature templates, the algorithm quickly identifies the battery model, specifications, production batch, and whether there are appearance defects (such as scratches, dents, bulges, etc.). For batteries with defects or abnormal parameters, the system quickly marks them and generates corresponding sorting instructions.

[0039] Once the control system generates a sorting command, the sorting mechanism responds immediately. The sorting mechanism typically employs high-speed pneumatic push rods, robotic arms, or electromagnetic sorting devices. For example, when a defective battery is detected, the robotic arm picks up the lithium battery from the conveyor belt 102 and moves it to the defective product collection area. For qualified lithium batteries, they are allowed to continue to be transported on the conveyor belt 102 to the qualified product collection area, thereby achieving precise sorting of lithium batteries and effectively improving the product quality and production efficiency of lithium batteries.

[0040] Example 2

[0041] Please see Figure 2 and Figure 4 This embodiment further illustrates Example 1. The rotating assembly shown in the figure includes a mounting bracket 501 fixedly connected to the sidewalls of the identification frame 201 near both ends of the lithium battery body 101. Two mounting brackets 501 are rotatably connected to rubber wheels 502. A motor 503 for driving the rubber wheels 502 to rotate is provided on the side of the two mounting brackets 501 that is far apart from each other. A rotating roller 504 is rotatably connected to the limiting frame 401. Both ends of the rotating roller 504 are provided through the limiting frame 401.

[0042] It should be noted that, through the setting of the rotating component, when the recognition frame 201 abuts against the end face of the limiting cover 402, the rubber wheels 502 on the two mounting brackets 501 will abut against the side wall of the rotating roller 504. Then, when the motor 503 drives the rubber wheels 502 to rotate, the friction between the rubber wheels 502 and the rotating roller 504 will drive the rotating roller 504 to rotate, which in turn drives the lithium battery body 101 to rotate, thereby improving the comprehensiveness of laser recognition of the lithium battery body 101.

[0043] Please see Figure 1 and Figure 4 The rotating roller 504 in the diagram has multiple anti-slip grooves interlaced on its side wall;

[0044] It should be noted that by setting multiple anti-slip grooves on the side wall of the rotating roller 504, the friction between the rotating roller 504 and the lithium battery body 101 and the rubber wheel 502 can be increased, thereby improving the stability of rotating the lithium battery body 101.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
