Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, specifically to an automatic raw material scanning and feeding system. Background Technology

[0002] In industries such as lithium batteries, chemicals, and food, the automated identification and processing of powder raw materials is a crucial aspect of intelligent manufacturing. Currently, powder raw materials are commonly packaged in woven bags or ton bags, each with a QR code printed on its surface containing key information such as batch number and composition. The accurate identification of these codes directly impacts the traceability of the production process, the precise control of process parameters, and the quality stability of the final product. With the continuous improvement of industrial automation, achieving efficient and accurate identification of powder packaging bags has become a significant challenge for technological development in the industry.

[0003] In existing technologies, powder raw materials are mostly packaged in bags, and their outer surfaces often become wrinkled and deformed due to transportation and stacking, resulting in uneven QR code areas. Traditional industrial camera scanning solutions face serious challenges under these conditions: the uneven bag surface makes it difficult for the camera to focus, significantly reducing the recognition success rate; secondly, existing equipment lacks effective bag positioning and flattening mechanisms, making it impossible to ensure that the QR code is always in the optimal recognition position. These shortcomings not only increase equipment maintenance costs but also severely restrict the operating efficiency of automated production lines, forcing companies to retain manual verification steps and making it difficult to achieve true end-to-end automation. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides an automatic raw material barcode scanning and feeding system with automatic flattening, positioning and identification functions, which solves the problem of QR code recognition difficulty caused by surface wrinkles of bagged powder.

[0005] (II) Technical Solution: To achieve the above-mentioned purpose of having automatic flattening, positioning and identification functions, this utility model provides the following technical solution: an automatic raw material scanning and feeding system, including a conveyor frame, a conveyor belt is provided on the conveyor frame, a powder bag to be scanned is placed on the upper surface of the conveyor belt, and the direction of movement of the conveyor belt is forward; a camera is provided above the upper surface of the conveyor belt; a flattening device is provided at the side end of the conveyor belt, and the flattening device is located at the rear end of the conveyor belt relative to the camera; the flattening device includes rollers, and when the powder bag to be scanned moves on the conveyor belt, the rollers flatten the upper surface of the powder bag to be scanned.

[0006] Preferably, the flattening device includes spring plates, which are disposed on both sides of the conveyor frame. The spring plates are connected to the conveyor frame by springs, which have a degree of freedom of scaling in the vertical direction.

[0007] Preferably, the spring pressure plates located on both sides of the conveyor frame are positioned correspondingly, and a rotating shaft is fixedly connected between the two spring pressure plates. The roller is sleeved on the rotating shaft through a bearing and can rotate freely along the outer surface of the rotating shaft. The rolling direction of the roller is the same as that of the conveyor belt. When the powder bag to be scanned passes under the roller, the roller flattens the upper surface of the powder bag to be scanned.

[0008] Preferably, the upper surface of the conveyor belt is provided with a guide groove, the guide groove has a V-shaped structure, the guide groove is made of a flexible material, and the lowest point of the guide groove coincides with the center line of the conveyor belt.

[0009] Preferably, the angle between the left and right inclined surfaces of the guide groove and the horizontal plane is in the range of 30-45 degrees.

[0010] Preferably, the outer surface of the roller is provided with an elastic protective layer.

[0011] Preferably, the length of the roller is greater than the width of the powder bag to be scanned.

[0012] (III) Beneficial Effects: Compared with the prior art, this utility model provides an automatic raw material scanning and feeding system, which has the following beneficial effects:

[0013] 1. This automatic raw material barcode scanning and feeding system uses a flattening device and rollers to flatten the upper surface of the powder bag to be scanned. The rollers are connected to the conveyor frame via spring pressure plates. The spring pressure plates have elastic lifting freedom in the vertical direction, so the rollers can flexibly adjust their position according to the thickness of the powder bag to be scanned, achieving flattening of powder bags of different sizes and shapes. After the upper surface of the powder bag is flattened, it moves to the area under the camera via a conveyor belt, where the camera scans and identifies the QR code on the bag. The flattening device significantly improves the flatness of the QR code area, greatly increasing the recognition success rate and effectively solving the problem of recognition failure caused by bag wrinkles in traditional methods. Compared with the existing technology that requires manual scanning one by one, this system integrates flattening, conveying and scanning functions into one, greatly improving work efficiency by replacing manual operation with a fully automated process, realizing a fully automatic barcode scanning system.

[0014] 2. This automatic raw material scanning and feeding system features a guide trough made of flexible material connected to the conveyor belt. This structure guides the flexible packaged powder bags to be scanned to automatically center on the conveyor belt during transport, creating favorable conditions for subsequent flattening and camera recognition. Furthermore, compared to the cumbersome process of manual scanning followed by material transfer using a lift in existing technologies, this system fully utilizes the continuous conveying characteristics of the conveyor belt to achieve automatic transfer and positioning of the scanned powder bags, simplifying the material flow process and significantly improving overall operational efficiency.

[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] Please see Figures 1-2An automatic raw material barcode scanning and feeding system includes a conveyor frame 1, a conveyor belt 5 mounted on the conveyor frame 1, and powder bags 2 to be scanned placed on the upper surface of the conveyor belt 5. The conveyor belt 5 moves forward. A camera 3 is mounted above the upper surface of the conveyor belt 5 and is connected to an image processing system. The camera 3 can scan and identify the QR code labels on the powder bags passing below. This camera 3 is existing technology and will not be described in detail here. A flattening device 4 is mounted on the side of the conveyor belt 5. The flattening device 4 is located at the rear end of the conveyor belt 5, so the upper surface of the powder bags passing below the camera 3 has been processed by the flattening device 4, making its upper surface flatter. The flattening device 4 includes rollers 41 and spring pressure plates 42. The spring pressure plates 42 are located on both sides of the conveyor frame 1 and are connected to the conveyor frame 1 by springs 43. The springs 43 have elastic extension and contraction freedom in the vertical direction and are located on the conveyor frame 1. The spring pressure plates 42 on both sides are positioned correspondingly, and a rotating shaft 44 is fixedly connected between the two spring pressure plates 42. The roller 41 is sleeved on the rotating shaft 44 through a bearing. When the powder bag 2 to be scanned moves on the conveyor belt 5, the roller 41 flattens the upper surface of the powder bag 2 to be scanned. The roller 41 flattens the upper surface of the powder bag 2 to be scanned, and the roller 41 is connected to the conveyor frame 1 through the spring pressure plate 42. The spring pressure plate 42 has elastic lifting freedom in the vertical direction, so the roller 41 can flexibly adjust its position according to the thickness of the powder bag 2 to be scanned, so as to flatten the powder bags 2 of different sizes and shapes. After the upper surface of the powder bag 2 to be scanned is flattened, it moves to the area below the camera 3 through the conveyor belt 5 and is scanned and identified by the camera 3. The flattening device 4 significantly improves the flatness of the QR code area, greatly improves the recognition success rate, and effectively solves the problem of recognition failure caused by bag wrinkles in the traditional method.

[0022] Please see Figure 1 and Figure 4 The roller 41 can rotate freely along the outer surface of the rotating shaft 44, thereby reducing the friction between the outer surface of the roller 41 and the upper surface of the powder bag 2 to be scanned, and preventing the powder bag 2 to be scanned from shifting on the conveyor belt 5. The rolling direction of the roller 41 is the same as that of the conveyor belt 5. An elastic protective layer 411 is provided on the outer surface of the roller 41. The length of the roller 41 is greater than the width of the powder bag 2 to be scanned. When the powder bag 2 to be scanned passes under the roller 41, the roller 41 flattens the upper surface of the powder bag 2 to be scanned, so that the camera 3 located at the rear can scan and photograph the upper surface of the powder bag 2 to be scanned.

[0023] Please see Figure 1 and Figure 3The upper surface of the conveyor belt 5 is provided with a guide groove 51, which has a V-shaped structure and is made of flexible material. The lowest point of the guide groove 51 coincides with the center line of the conveyor belt 5. The angle between the left and right inclined surfaces of the guide groove 51 and the horizontal plane is between 30 and 45 degrees. This structure can guide the flexible packaged powder bag 2 to be scanned to automatically center to the center line of the conveyor belt 5 during the conveying process, creating favorable conditions for subsequent flattening and camera 3 recognition. At the same time, compared with the cumbersome process of manual scanning and material transfer by elevator in the existing technology, this system makes full use of the continuous conveying characteristics of the conveyor belt 5 to realize the automatic transmission and positioning of the powder bag after scanning, simplifying the material flow process and significantly improving the overall operation efficiency.

[0024] In summary, the roller 41 connected to the spring pressure plate 42 in the flattening device 4 allows the roller 41 to flexibly adjust its position according to the thickness of the powder bag 2 to be scanned, achieving automatic flattening of packaging bags of different sizes. This significantly improves the flatness of the QR code area and effectively solves the problem of recognition failure caused by bag wrinkles in traditional methods. Simultaneously, the system features a flexible guide groove 51 on the conveyor belt 5 to guide the powder bag to automatically center it to the center line of the conveyor belt 5, creating favorable conditions for subsequent processing. Compared to the cumbersome process of manual scanning followed by material transfer using an elevator in existing technologies, this system integrates flattening, centering, conveying, and scanning functions into one, fully utilizing the continuous conveying characteristics of the conveyor belt 5 to achieve full automation from scanning and identification to material positioning, greatly improving operational efficiency and simplifying material flow.
