Description

Technical Field

[0001] This invention relates to the field of lithium battery production technology, specifically to the design of an automatic appearance inspection and barcode scanning mechanism for cylindrical batteries. Background Technology

[0002] In the current era of rapid development in the new energy industry, cylindrical batteries, with their high energy density, good structural stability, and excellent charge-discharge performance, have been widely used in many fields such as new energy vehicles, portable electronic devices, and energy storage systems. As market demand continues to expand, the production scale of cylindrical batteries is constantly increasing, and the requirements for their production efficiency and product quality are becoming increasingly stringent. Appearance quality and traceability are key links in the entire battery production process, directly affecting the battery's safety, reliability, and full lifecycle management capabilities. Therefore, building an efficient and accurate automated appearance inspection and barcode traceability system has become an inevitable requirement for industry development.

[0003] Cylindrical batteries exhibit a variety of surface defects, primarily including scratches on the casing, dents, bulges, leakage, deformed tabs, and damaged insulation. These defects not only affect the battery's sealing performance but can also lead to internal electrolyte leakage, poor electrode contact, and in severe cases, even short circuits and fires.

[0004] Traditional visual inspection methods rely primarily on manual visual inspection. This approach is susceptible to problems such as low efficiency, high rates of missed or false positives, and inconsistent inspection standards, due to factors like subjective judgment, visual fatigue, and differences in experience among inspectors. It can no longer meet the "high-speed, high-precision, and large-scale" inspection requirements of modern production lines. Therefore, this invention proposes an automated visual inspection and barcode scanning mechanism for cylindrical batteries. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an automatic appearance inspection and barcode scanning mechanism design for cylindrical batteries, which solves the problems of low efficiency, high rate of missed and false detections, and inconsistent inspection standards in traditional manual appearance inspection.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an automatic appearance inspection and barcode scanning mechanism for cylindrical batteries, comprising a rotating platform, a vision and barcode scanning mechanism, and a photoelectric detection mechanism. The rotating platform uses its base plate as the core mounting reference. The vision and barcode scanning mechanism is fastened to the base plate of the rotating platform through its fixed base plate. The photoelectric detection mechanism is correspondingly connected to the base plate of the rotating platform through its mounting bracket.

[0010] Preferably, the camera fine-tuning assembly further includes a rotating adapter plate and an adjusting adapter plate, which are stacked and fastened to the outer wall of the middle part of the camera adjusting plate. The camera component can be adjusted in the front-back and left-right directions by the adjusting screw between the adjusting block and the camera adjusting plate, and the camera component can be adjusted in angle by the relative rotation of the rotating adapter plate and the adjusting adapter plate, together forming a multi-dimensional adjustment structure for the camera component.

[0011] Preferably, the scanning assembly includes a support frame, a barcode scanner, and a barcode mounting bracket; the support frame is vertically positioned on the side of the adjustment adapter plate away from the camera adjustment plate, and the barcode mounting bracket has an L-shaped structure, with its vertical section firmly connected to the middle side wall of the support frame, and the barcode scanner fixed to the lower surface of its horizontal section, with the scanning end of the barcode scanner vertically downward and aligned with the area directly above the magnetic cup; the barcode scanner can be adjusted in angle and four directions synchronously with the adjustment adapter plate via the support frame.

[0012] Preferably, the light source assembly includes a side bracket, a light source adapter block, a light source mounting bracket, and a light source plate; the side bracket is vertically fixed to the upper surface of the base plate of the rotating platform and is located on the side of the camera component away from the magnetic cup; the light source adapter block is vertically adjustable and connected to the top of the side bracket, the light source mounting bracket is horizontally fixed to the side of the light source adapter block facing the magnetic cup, and the light source plate is mounted on the light source mounting bracket with its light-emitting surface facing the surface of the cylindrical battery component on the magnetic cup; the light source adapter block allows for angular rotation and four-directional position adjustment of the light source plate.

[0013] Preferably, the photoelectric detection mechanism includes a mounting bracket, a photoelectric support rod, a bracket fixing clamp, a photoelectric sensor, and a sensor bracket; the mounting bracket is horizontally fixed to the upper surface of the base plate of the rotating machine platform and located in the side area of ​​the magnetic cup; the photoelectric support rod is vertically fixed to the upper surface of the mounting bracket; the bracket fixing clamp is adjustablely sleeved on the mounting bracket along the vertical direction of the mounting bracket and is fixedly connected to the end of the photoelectric support rod facing the mounting bracket; the sensor bracket is horizontally arranged on one side of the bracket fixing clamp and fixedly connected to the middle section of the photoelectric support rod along the vertical direction of the photoelectric support rod; the photoelectric sensor is mounted on one side of the sensor bracket and distributed on one side of the magnetic cup.

[0014] In summary, the technical effects and advantages of this invention are as follows: 1. This invention utilizes a worm gear transmission structure and a servo motor in precise coordination to drive a magnetic cup to rotate a cylindrical battery component smoothly 360°. The rotation process is completely synchronized with the high-speed imaging by the vision camera and the information acquisition by the barcode scanner. Compared to the traditional intermittent "rotation-stop-detection-scanning" process, this mechanism significantly shortens the single-battery detection and scanning cycle, effectively adapting to the operational needs of high-speed production lines, and substantially improving production efficiency compared to manual operation and semi-automatic equipment. The facility integrates the entire process of "battery positioning - appearance inspection - information scanning - NG removal," eliminating the need for manual intervention during transport or secondary operations. Through real-time data linkage between the vision system and the scanning module, it can automatically bind and record the appearance defects and identification information of unqualified battery cells, triggering the subsequent waste removal mechanism to accurately remove NG products, achieving closed-loop management of "inspection-traceability-sorting." This design effectively avoids the problems of mixing and missing materials caused by manual sorting, significantly enhancing the continuity of the production process.

[0015] 2. In the vision and scanning mechanism of this invention, the camera fine-tuning component, through the combined design of the adjusting screw, rotating adapter plate, and adjusting adapter plate, achieves multi-directional fine-tuning and angle adjustment of the camera component. Combined with the adjustable light emission angle and brightness of the light source plate, it can accurately focus on the curved area of ​​the cylindrical battery component, effectively eliminating light and shadow interference. The barcode scanner, through the linkage adjustment of the support frame and the adjusting adapter plate, can accurately align with the QR code / laser code on the top or side of the battery. Even if the battery has slight eccentricity due to processing errors, scanning alignment can be achieved through angle and position fine-tuning. Improved battery positioning stability: The magnetic cup uses magnetic force to attract cylindrical battery components, and combined with the high-precision coaxiality design of the turbine shaft, it effectively prevents the battery from slipping or shifting during 360° rotation, ensuring stable positioning. This design avoids detection ambiguity and barcode misalignment caused by battery movement, significantly enhancing the consistency of detection and traceability.

[0016] 3. In this invention, the photoelectric detection mechanism employs two sets of through-beam photoelectric sensors: one set horizontally detects the battery's tilt, and the other vertically detects the battery's excessive height. The status can be pre-judged before the battery enters the detection area. If an anomaly is detected, the system immediately triggers the servo motor to stop, preventing the tilted battery from colliding with the camera lens or barcode scanner, or the excessively tall battery from interfering with the mechanism frame. Compared to traditional methods without pre-detection equipment, this mechanism significantly reduces the collision failure rate and effectively controls equipment maintenance costs. The main frame of the rotary table is rigidly connected to the fixed plate, base plate, and support columns to form a vibration-resistant structure. Combined with the buffer design of the internal coupling and connecting shaft series in the drive transmission assembly, it effectively absorbs vibrations from the servo motor during operation. This robust design allows the equipment to maintain a low failure rate even under long-term continuous operation, significantly extending its service life compared to similar equipment and greatly improving its overall utilization rate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figures 1-6 The design of an automatic appearance inspection and barcode scanning mechanism for cylindrical batteries, as shown, includes a rotating platform 1, a vision and barcode scanning mechanism 2, and a photoelectric detection mechanism 3. A specific embodiment is shown below: Example 1: This mechanism uses the base plate 12 of the rotating platform 1 as a unified installation reference. The vision and barcode scanning mechanism 2 and the photoelectric detection mechanism 3 are fixed to the base plate 12 via the fixed base support plate 21 and the mounting bracket 31, respectively. The three form a collaborative detection layout around the magnetic suction cup 114. This integrated design breaks through the limitations of the traditional equipment's dispersed functions, realizing the integrated operation of cylindrical battery appearance inspection, identification information collection, and placement status monitoring. It significantly reduces process connection time, making the battery inspection process more efficient and continuous, and providing a stable end-to-end solution for high-speed production lines.

[0021] Example 2: The rotating platform 1 consists of a main frame and a drive transmission assembly. The main frame is rigidly connected to the base plate 12 and the fixed plate 11 through support columns 13, forming a stable, vibration-resistant structure. In the drive transmission assembly, the servo motor 117 and the bearing seat 17 are precisely fixed to the fixed plate 11, and the rotational engagement between the transition plate 14 and the bearing component 15 provides a solid foundation for subsequent battery rotation testing. This frame design can effectively withstand the load of long-term equipment operation, avoid affecting the testing accuracy due to structural shaking, and extend the continuous working time of the equipment.

[0022] Example 3: The drive transmission assembly of the rotating machine achieves its core drive function through the collaborative operation of multiple components. The servo motor 117 drives the worm gear 16 via a series of couplings and a connecting shaft. Through the meshing of the worm gear and worm wheel, the worm shaft 113 rotates, ultimately causing the magnetic cup 114 at the top to operate smoothly. The core advantage lies in the combination of the precise control of the servo motor 117 and the transmission characteristics of the worm gear and worm wheel, which enables the battery to rotate 360° without dead angles. Combined with the magnetic positioning of the magnetic cup 114, battery slippage and offset are completely avoided, ensuring the stability of the target position during subsequent inspection and scanning processes, thus improving inspection reliability from the source.

[0023] Example 4: The camera fine-tuning component of the vision and scanning mechanism 2 is key to improving detection accuracy. The fixed base plate 21 provides a stable mounting foundation, and the cooperation between the adjusting block 22 and the adjusting screw 25 allows the camera adjusting plate 23 to be flexibly adjusted in position, ensuring that the camera component 27 is precisely aligned with the battery on the magnetic cup 114. The camera cover 26 effectively isolates dust and vibration interference in the production environment, protecting the core detection components and extending the service life of the camera component 27. This adjustable design allows the mechanism to adapt to cylindrical battery components 119 of different specifications without the need to replace special parts, reducing changeover costs.

[0024] Example 5: The rotating adapter plate 29 and adjusting adapter plate 210 of the camera fine-tuning component, together with the adjusting screw 25, form a multi-dimensional adjustment structure, which can easily calibrate the angle and position of the camera component 27, ensuring that it can clearly capture the subtle defects of the battery surface. The barcode scanning component is linked with the adapter plate through the support frame 211, so that the barcode scanner 213 is always aligned with the barcode area of ​​the battery. Even if there is slight processing misalignment of the battery, it can be quickly adjusted and adapted, greatly improving the scanning success rate. A sliding structure can be configured later to connect and drive the entire structure on the support frame 211 to adapt to the barcode scanning cylindrical battery component 119. This "detection-scanning" linkage adjustment design allows the data of the two to be accurately bound, providing reliable data association guarantee for battery quality traceability.

[0025] Example 6: The adjustable design of the light source assembly via the side bracket 212 and the light source adapter block 215 allows the light emission angle and position of the light source board 217 to flexibly adapt to battery testing requirements. The light from the light source can be precisely focused on the battery surface, effectively eliminating interference from curved surface light and shadow, allowing the camera component 27 to clearly identify defects such as minor scratches and bulges, avoiding missed or incorrect detections due to lighting issues. At the same time, the directional illumination design of the light source reduces light pollution and minimizes the aging impact on surrounding components, balancing testing effectiveness with equipment maintenance costs.

[0026] Example 7: The photoelectric detection mechanism 3 achieves dual protection through a through-beam photoelectric sensor 34. The sensor is strategically positioned on the side of the magnetic cup 114, enabling early detection of battery misalignment or excessive height. Upon detection of an anomaly, it immediately triggers a shutdown, preventing collisions between the battery and core components such as the camera 27 and barcode scanner 213, significantly reducing equipment wear and maintenance costs. This pre-detection design makes equipment operation safer and more stable, especially suitable for unattended automation production lines, reducing production accidents caused by untimely human intervention.

[0027] Working principle of this invention: The overall mechanism is centered on the rotating platform 1. Through the coordinated operation of rotation drive, visual inspection, barcode scanning traceability, and photoelectric protection, it completes the entire battery inspection process. During operation, the cylindrical battery component 119 is first placed on the magnetic cup 114 of the rotating platform 1. The magnetic cup 114 quickly positions the battery using magnetic force to prevent displacement during subsequent rotation.

[0028] After the battery is positioned, the photoelectric detection mechanism 3 starts first, and two sets of through-beam photoelectric sensors 34 detect whether the battery is tilted or at an abnormal height. If an abnormality is detected, the system immediately triggers the servo motor 117 to stop to prevent the battery from colliding with equipment components; if the detection is normal, the subsequent process is triggered. The servo motor 117 of the rotating platform 1 drives the worm gear 16 to rotate through the plum blossom coupling 118. The worm gear 18 meshes with the worm gear 16, driving the turbine shaft 113 and the magnetic cup 114 at the top to rotate smoothly, enabling the battery to rotate 360° without dead angles.

[0029] Simultaneously, the vision and scanning mechanism 2 is activated. The light source assembly precisely illuminates the battery surface through the adjustable light source plate 217, eliminating interference from curved surface light and shadow, and providing a clear environment for visual inspection. The camera fine-tuning assembly, through a multi-dimensional adjustment structure consisting of a rotating adapter plate 29, an adjusting adapter plate 210, and an adjusting screw 25, allows the lens 28 of the camera component 27 to focus on the battery surface, capturing appearance images in real time as the battery rotates, and quickly identifying defects such as scratches and bulges.

[0030] The barcode scanning component and the camera fine-tuning component work together. The barcode scanner 213 is adjusted and aligned with the battery barcode area by the adjustment adapter plate 210. During the battery rotation, the barcode information is collected, and the data is linked to the detection results of the camera component 27 in real time. After detection and barcode scanning, the system automatically determines whether the battery is qualified. Unqualified products are precisely discharged by triggering the waste discharge mechanism, while the traceability information of qualified products is simultaneously uploaded to the management system, realizing a closed-loop operation of "detection-traceability-sorting". The base plate 12 of the rotating platform 1 provides stable support for each component, ensuring the stability and reliability of the entire process.

[0031] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
