Description

Technical Field

[0001] This utility model belongs to the field of battery carbon rod production technology, and relates to a battery carbon rod testing and sorting machine. Background Technology

[0002] As a key component of batteries, the quality of battery carbon rods directly affects battery performance, lifespan, and safety. However, quality control of battery carbon rods faces numerous challenges in traditional production processes, especially due to the limitations of manual inspection, which cannot effectively handle high production speeds and high precision requirements. This leads to defective products not being removed in a timely manner, thus affecting the overall battery quality. Currently, although machine vision technology is widely used in industrial inspection, it still faces several problems in defect detection of battery carbon rods. First, due to the complex shape and surface condition of battery carbon rods, existing technologies may miss some minor defects when handling comprehensive defect detection, thus affecting product quality control. Furthermore, while there has been progress in automation and intelligence, many production lines still cannot completely eliminate manual operation. Especially in the defect removal and packaging processes, many production lines still rely on manual intervention, which not only reduces production efficiency but also increases the possibility of human error. This reliance on manual labor affects the stability and consistency of the production line, making it impossible to guarantee that every carbon rod is accurately inspected and processed. Simultaneously, existing conveying systems and inspection equipment are prone to problems such as carbon rod overlap, missed detections, and misalignment when handling high-speed, high-volume production. Because overlapping of carbon rods was not effectively avoided during the conveying process, the detection system could not perform timely and accurate independent inspection of each carbon rod, increasing the risk of missed detections and thus affecting the final product's pass rate. In summary, current carbon rod defect detection and sorting still suffer from problems such as insufficient comprehensive inspection, low automation, low production efficiency, and excessive manual intervention. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a battery carbon rod detection and sorting machine that reduces missed detections.

[0004] The objective of this utility model can be achieved through the following technical solution: a battery carbon rod detection and sorting machine, including a second sorting mechanism, the second sorting mechanism including a synchronous toothed belt and a sorting drive motor, the sorting drive motor driving the synchronous toothed belt to move, the second sorting mechanism also including a first camera, a second camera, a third camera and an air nozzle arranged sequentially on the synchronous toothed belt, the first camera and the second camera being located on both sides of the synchronous toothed belt and staggered front and back, a number of battery carbon rods being placed on the synchronous toothed belt, the first camera, the second camera and the third camera taking pictures of the battery carbon rods and transmitting them to the controller to identify defective battery carbon rods with end notches and lengths that are too long or too short, the controller controlling the air nozzle to blow off the defective battery carbon rods.

[0005] In the aforementioned battery carbon rod inspection and sorting machine, a plurality of sorting grooves for placing battery carbon rods are uniformly formed on the synchronous toothed belt. A sorting baffle is also arranged parallel above the synchronous toothed belt. A first detection notch is formed on the sorting baffle at a position corresponding to the first camera, and a second detection notch is formed on the sorting baffle at a position corresponding to the second camera. The two ends of the battery carbon rod are exposed sequentially from the first detection notch and the second detection notch, respectively. The first camera takes a picture of the end of the battery carbon rod exposed from the first detection notch to identify end defects. The second camera takes a picture of the end of the battery carbon rod exposed from the second detection notch to identify end defects. A third camera is located above the synchronous toothed belt. Two third detection notches are formed on the sorting baffle. The third detection notches are located directly below the third camera. The two ends of the battery carbon rod are exposed from the third detection notches. The third camera takes a picture of the battery carbon rod exposed from the third detection notches to identify the length of the battery carbon rod.

[0006] In the aforementioned battery carbon rod inspection and sorting machine, the air nozzle is located on the side of the synchronous toothed belt. The air inlet of the air nozzle is connected to an air compressor through an air pipe, and the air outlet of the air nozzle faces the synchronous toothed belt and can blow off the defective battery carbon rods on the synchronous toothed belt by outputting a strong airflow.

[0007] The battery carbon rod detection and sorting machine described above also includes a feeding and conveying mechanism, a first sorting mechanism, and a transfer mechanism. The battery carbon rods pass through the feeding and conveying mechanism, the first sorting mechanism, and the transfer mechanism in sequence and are then located on the synchronous toothed belt.

[0008] In the aforementioned battery carbon rod detection and sorting machine, the feeding and conveying mechanism includes a feeding conveyor belt and a feeding motor. The feeding motor drives the feeding conveyor belt to move. Several battery carbon rods are placed on the feeding conveyor belt. A pressing baffle is also provided parallel above the feeding conveyor belt. The longitudinal space between the pressing baffle and the feeding conveyor belt allows the battery carbon rods lying flat on the feeding conveyor belt to pass through.

[0009] In the aforementioned battery carbon rod detection and sorting machine, the first sorting mechanism includes a sorting block connected to the feeding conveyor belt. The sorting block has a sorting drop hole in its center, and a sorting baffle is provided above the sorting block, extending above the feeding conveyor belt. The battery carbon rods on the feeding conveyor belt move to the sorting block and are pressed forward by subsequent battery carbon rods. When the middle of a battery carbon rod breaks, it falls into the sorting drop hole. Unbroken battery carbon rods continue to move forward to the transfer mechanism under the pressure of subsequent battery carbon rods.

[0010] In the aforementioned battery carbon rod inspection and sorting machine, the transfer mechanism includes a single-track curved-straight flow channel, a brush wheel, and a guide wheel. The inlet of the single-track curved-straight flow channel is connected to the tail of the first sorting mechanism. The single-track curved-straight flow channel includes a connected curved flow channel and a vertical straight flow channel. The curved flow channel is located above the straight flow channel. The single-track curved-straight flow channel is used to arrange the battery carbon rods for vertical placement. The brush wheel is driven to rotate by a brush wheel motor. The side of the single-track curved-straight flow channel has an opening for the brush wheel to pass through. The brush wheel enters the opening and contacts the battery carbon rod. The rotation of the brush wheel assists in moving the battery carbon rod in the single-track curved flow channel downward. The guide wheel is provided with several guide wheel grooves evenly spaced on its circumference to accommodate one battery carbon rod. The guide wheel is driven to rotate by the guide wheel motor. The battery carbon rod on the first sorting mechanism moves to the single-track curved flow channel. The battery carbon rod falling in the single-track curved flow channel enters the guide wheel groove on the guide wheel. The guide wheel drives the battery carbon rod to rotate to the second sorting mechanism.

[0011] Compared with existing technologies, this battery carbon rod detection and sorting machine transmits images captured by a first, second, and third camera to a controller to identify defective battery carbon rods with end notches, excessive length, or excessive shortness. It then controls an air nozzle to blow away the defective carbon rods, ensuring that defective rods are sorted out and reducing missed detections. The air nozzle uses a strong airflow to quickly blow away detected defective carbon rods, ensuring they are promptly removed and preventing them from affecting the quality of qualified carbon rods, thus improving removal efficiency and accuracy. The defective carbon rods blown away by the air nozzle fall into a recycling box through a recycling tube. The collection process is carried out internally; the sorting grooves on the synchronous toothed belt allow each battery carbon rod to be placed individually and limit the placement of the battery carbon rods, avoiding overlapping or tilting of the battery carbon rods and causing missed detection, thus avoiding affecting the final product qualification rate; the first sorting mechanism sorts the battery carbon rods that are broken in the middle, causing the broken battery carbon rods to fall into the sorting drop hole; through the coordinated work of the feeding conveyor mechanism, the first sorting mechanism, the transfer mechanism, and the second sorting mechanism, the automated carbon rod conveying and defect removal are realized, reducing manual intervention, lowering production costs and human error, and improving production efficiency and consistency.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 and Figure 2 As shown, this battery carbon rod detection and sorting machine includes a feeding and conveying mechanism 1, a first sorting mechanism 2, a transfer mechanism 3, and a second sorting mechanism 4.

[0017] In the above technical solution: the feeding conveyor mechanism 1 includes a feeding conveyor belt 11 and a feeding motor. The feeding motor drives the feeding conveyor belt 11 to move, and several battery carbon rods are placed on the feeding conveyor belt 11. A pressing baffle 12 is also provided parallel above the feeding conveyor belt 11. The longitudinal space between the pressing baffle 12 and the feeding conveyor belt 11 allows the battery carbon rods placed flat on the feeding conveyor belt 11 to pass through. The pressing baffle 12 prevents the battery carbon rods from overlapping during feeding, ensuring that the battery carbon rods are neatly arranged during feeding. At the same time, the pressing baffle 12 prevents the battery carbon rods from detaching from the feeding conveyor belt 11 during its movement.

[0018] In the above technical solution: the first sorting mechanism 2 includes a sorting block 21 connected to the feeding conveyor belt 11. A sorting drop hole 22 is formed in the middle of the sorting block 21. A sorting baffle 23 is provided above the sorting block 21, extending above the feeding conveyor belt 11. Battery carbon rods on the feeding conveyor belt 11 move to the sorting block 21 and are pressed forward by subsequent battery carbon rods. The sorting baffle 23 prevents the battery carbon rods from stacking, ensuring that the battery carbon rods are neatly arranged. When the middle of a battery carbon rod breaks, it falls into the sorting drop hole 22 and is discarded as a defective product. Unbroken battery carbon rods continue to move forward to the transfer mechanism 3 under the pressure of subsequent battery carbon rods.

[0019] In the above technical solution: the transfer mechanism 3 includes a single-track curved-straight flow channel 31, a brush wheel 32, and a guide wheel 33. The inlet of the single-track curved-straight flow channel 31 is connected to the tail of the first sorting mechanism 2. The single-track curved-straight flow channel 31 includes a connected curved flow channel and a vertical straight flow channel. The curved flow channel is located above the straight flow channel. The single-track curved-straight flow channel 31 is used to arrange the battery carbon rods vertically, preventing the battery carbon rods after passing through the first sorting mechanism 2 from stacking during the downward movement. At the same time, the curved flow channel can reduce the falling speed of the battery carbon rods, making them easier to arrange. The brush wheel 32 is driven to rotate by the brush wheel motor 34. The brush wheel 32 is located on the side of the single-track curved-straight flow channel 31. Specifically, the brush wheel 32 is located on the side of the straight flow channel. The side of the single-track curved-straight flow channel 31 has an opening for the brush wheel 32 to pass through. The brush wheel 32 enters the opening and contacts the battery carbon rod. The rotation of the brush wheel 32 assists in moving the battery carbon rods in the single-track curved-straight flow channel 31 downward, preventing the battery carbon rods from blocking the single-track curved-straight flow channel 31. The guide wheel 33 has several evenly spaced guide wheel grooves on its circumference, each capable of accommodating a single battery carbon rod. The guide wheel 33 is driven to rotate by a guide wheel motor. The battery carbon rod on the first sorting mechanism 2 moves to the monorail curved straight flow channel 31. The battery carbon rod falling into the monorail curved straight flow channel 31 enters the guide wheel groove on the guide wheel 33. The guide wheel 33 drives the battery carbon rod to rotate to the second sorting mechanism 4. The guide wheel 33 is used to change the direction of travel of the battery carbon rod between the monorail curved straight flow channel 31 and the second sorting mechanism 4.

[0020] In the above technical solution: the second sorting mechanism 4 includes a synchronous toothed belt 41 and a sorting drive motor 49, which drives the synchronous toothed belt 41 to move. The synchronous toothed belt 41 has multiple sorting grooves evenly formed on it for placing battery carbon rods. Each sorting groove holds one battery carbon rod. A sorting baffle 42 is also arranged parallel above the synchronous toothed belt 41. After passing through the feeding and conveying mechanism 1, the first sorting mechanism 2, and the transfer mechanism 3 in sequence, the battery carbon rods are located in the sorting grooves on the synchronous toothed belt 41, so that several battery carbon rods are placed on the synchronous toothed belt 41. The second sorting mechanism 4 also includes a first camera 43, a second camera 44, a third camera 45, and an air nozzle 46 sequentially arranged on the synchronous toothed belt 41. The first camera 43 and the second camera 44 are located on both sides of the synchronous toothed belt 41 and are staggered. A first detection notch 421 is formed on the sorting baffle 42 at the position corresponding to the first camera 43, and a second detection notch 422 is formed on the sorting baffle 42 at the position corresponding to the second camera 44. The two ends of the battery carbon rod are exposed from the first detection notch 421 and the second detection notch 422 respectively. The first camera 43 takes a picture of the end of the battery carbon rod exposed from the first detection notch 421 to identify end defects, and the second camera 44 takes a picture of the end of the battery carbon rod exposed from the second detection notch 422 to identify end defects. The third camera 45 is located above the synchronous toothed belt 41. Two opposing third detection notches 423 are formed on the sorting baffle 42, directly below the third camera 45. The ends of the battery carbon rods are exposed through the third detection notches 423. The third camera 45 photographs the exposed battery carbon rods to identify their length. An air nozzle 46 is located on the side of the synchronous toothed belt 41. The air inlet of the air nozzle 46 is connected to an air compressor via an air pipe, and the air outlet of the air nozzle 46 faces the synchronous toothed belt 41, capable of blowing off defective battery carbon rods from the synchronous toothed belt 41 by outputting a strong airflow. The first camera 43, the second camera 44, and the third camera 45 photograph the battery carbon rods and transmit the images to the controller to identify end notches and defective battery carbon rods that are too long or too short. The controller controls the solenoid valve to open the air compressor, causing the air nozzle 46 to blow off the defective battery carbon rods. The side of the synchronous toothed belt 41 is also provided with a recycling tube 47, which is arranged opposite to the air nozzle 46. A recycling frame 48 is provided below the recycling tube 47. The defective battery carbon rods blown off by the air nozzle 46 fall into the recycling frame 48 through the recycling tube 47.

[0021] In this battery carbon rod inspection and sorting machine, images captured by the first camera 43, the second camera 44, and the third camera 45 are transmitted to the controller to identify defective battery carbon rods with end notches, excessive length, or excessive shortness. The controller then controls the air nozzle 46 to blow away the defective carbon rods, ensuring that defective carbon rods are sorted out and reducing missed detections. The air nozzle 46 can quickly blow away detected defective carbon rods with a strong airflow, ensuring that defective carbon rods are promptly removed, avoiding affecting the quality of qualified carbon rods, and improving removal efficiency and accuracy. The defective battery carbon rods blown away by the air nozzle 46 fall into the recycling box 48 through the recycling pipe 47. The carbon rods are collected internally; the sorting grooves on the synchronous toothed belt 41 allow each battery carbon rod to be placed individually and limit the placement of the battery carbon rods to avoid overlapping or tilting of the battery carbon rods, which would cause missed inspections and affect the final product qualification rate; the first sorting mechanism 2 sorts the battery carbon rods that are broken in the middle, so that the broken battery carbon rods fall into the sorting drop hole 22; through the coordinated work of the feeding conveyor mechanism 1, the first sorting mechanism 2, the transfer mechanism 3, and the second sorting mechanism 4, the carbon rod conveying and defect removal are automated, reducing manual intervention, production costs and human error, and improving production efficiency and consistency.
