Description

Technical Field

[0001] This invention belongs to the field of battery processing technology, and in particular relates to an image recognition and monitoring system for battery packaging lines. Background Technology

[0002] During the battery manufacturing process, there are issues such as missing, crooked, damaged, or incorrectly affixed labels, improper installation of battery accessories, damage to accessories, and missing traceability codes. Generally, the quality of a battery is determined by manually observing its appearance.

[0003] Manual inspection has the following drawbacks:

[0004] 1. Judgment errors exist. For example, humans cannot accurately judge the precise distance between the label placement position and the intended label placement position, resulting in judgment errors.

[0005] 2. It is easy to miss cases.

[0006] To address the aforementioned issues, an image recognition and monitoring system for battery packaging lines is designed to monitor the appearance information of batteries and assess their product quality. Summary of the Invention

[0007] This invention addresses the problems of manual inspection in existing technologies by proposing the following technical solution:

[0008] A video recognition and monitoring system for a battery packaging line includes:

[0009] Conveying unit one transports the battery to be tested to the testing position;

[0010] An image acquisition unit is set at the detection position and is used to acquire the appearance information of the battery to be tested.

[0011] An illumination unit is located at the detection position and provides a light source for the image acquisition unit to acquire appearance information of the battery to be detected.

[0012] The computer terminal is connected to the image acquisition unit. The computer terminal is used to store the appearance information of qualified batteries and compare it with the appearance information of the battery to be tested acquired by the image acquisition unit to determine whether the appearance of the battery is qualified.

[0013] As a preferred embodiment of the above technical solution, a defective product ejection unit is also included, which ejects batteries with substandard appearance from the conveying track of the conveying unit one.

[0014] Conveying unit two is set up opposite to the defective product ejection unit. Conveying unit two transports the batteries on the conveying track of ejection conveying unit one.

[0015] Defective batteries should be disposed of promptly to prevent their accumulation.

[0016] As a preferred embodiment of the above technical solution, it also includes two sets of limiting mechanisms correspondingly arranged on both sides of the conveying unit. The battery passes between the two sets of limiting mechanisms, and the limiting mechanisms complete the operation of limiting the movement trajectory of the battery.

[0017] As a preferred embodiment of the above technical solution, the limiting mechanism includes a roller group consisting of roller one, roller two and roller three. Roller one is connected to the driving component. Roller one, roller two and roller three are externally sleeved with the same transmission belt. The outer ring of the transmission belt is provided with a push rod.

[0018] The line connecting roller 2 and roller 3 is set parallel to the edge line of conveying unit 1, and the line connecting roller 1 and roller 2 intersects the edge line of conveying unit 1. The distance between two roller 1s is greater than the distance between two roller 2s.

[0019] As a preferred embodiment of the above technical solution, the limiting mechanism further includes a plate, which is disposed inside the transmission belt and located between roller one and roller two, and between roller two and roller three.

[0020] The plate design provides rigid support for the push rod, preventing it from failing to reach the correct position when pushing the battery due to the deformation capacity of the transmission belt.

[0021] As a preferred embodiment of the above technical solution, the inner ring of the transmission belt is provided with a limiting belt, the first roller, the second roller and the third roller are provided with annular grooves that match the limiting belt, the plate is provided with a strip groove that matches the limiting belt, and the top rod is provided at a position corresponding to the limiting belt.

[0022] The combination of the limiting belt and the annular groove and strip groove prevents the transmission belt from flipping up and down, while keeping the push rod in a horizontal state to ensure the pushing effect of the push rod on the battery.

[0023] As a preferred embodiment of the above technical solution, the push rod includes a threaded sleeve connected to the transmission belt, a screw is threadedly fitted in the threaded sleeve, and a block is connected to one end of the screw located outside the threaded sleeve, the movable end of the block being a rubber end.

[0024] The push rod is composed of a threaded sleeve and a screw, which allows the overall length of the push rod to be changed. The overall length can be adjusted according to the specifications of the battery to be tested, making it adaptable and highly flexible.

[0025] As a preferred embodiment of the above technical solution, the conveying unit includes a frame, a conveying roller mounted on the frame, and a drive component that drives the conveying roller to rotate.

[0026] The conveying roller includes a shaft 1, and two ends of the shaft 1 are connected to a shaft 2 that cooperates with the driving component. The shaft 1 and the shaft 2 are fitted with a sleeve body. A ring body extends radially from the inner wall of the sleeve body corresponding to the middle part of the shaft 1. A spring is provided between the ring body and the shaft 2.

[0027] As a preferred embodiment of the above technical solution, a groove is provided on the shaft 2, and a rod is provided on the sleeve corresponding to the inner wall of the groove. One end of the rod is provided with a roller and inserted into the interior of the groove.

[0028] The rods provide support points for the sleeve, thereby increasing its load-bearing capacity.

[0029] The beneficial effects of this invention are as follows:

[0030] The installation of an image recognition monitoring system on the battery packaging line can effectively prevent the omission or incorrect installation of battery accessories, including but not limited to plugs, handles, safety valves, photoelectric sensors, and coding devices. It can effectively determine whether the label position is qualified and whether the label is peeling, damaged, reversed, or missing, thereby improving product quality.

[0031] The limit mechanism is designed to adjust and maintain the movement trajectory of the battery, preventing the battery from shifting its position during operation and causing invalid image captures, thus improving the effectiveness of the battery packaging line image recognition monitoring system.

[0032] The conveyor roller is composed of an internal shaft 1 and shaft 2 and an external sleeve. While supporting the battery and fulfilling the conveying requirements, the limiting mechanism and the defective product ejection unit push the battery to move in the axial direction of the conveyor roller, and the sleeve moves at the same time to reduce the friction between the battery shell and the conveyor roller and reduce the wear of the battery shell.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0039] Example 1

[0040] Figure 1 The diagram shown is a structural schematic of the image recognition and monitoring system for the battery packaging line in this embodiment. Figure 2 The diagram shown is a top view of the image recognition and monitoring system for the battery packaging line in this embodiment.

[0041] refer to Figure 1 , Figure 2 The battery packaging line image recognition and monitoring system includes a conveying unit 10, an image acquisition unit 20, an illumination unit 30, a computer terminal 40, a defective product ejection unit 50, a second conveying unit 60, and a limiting mechanism 80. In this embodiment, it also includes a protective housing 70. The first conveying unit 10 passes through the housing 70. The image acquisition unit 20, the illumination unit 30, the defective product ejection unit 50, and the limiting mechanism 80 are all installed inside the housing 70. The computer terminal 40 is installed on the outer wall of the housing 70.

[0042] Conveying unit 10 transports the battery to be tested to the testing position;

[0043] Image acquisition unit 20 is positioned at the detection location. It is used to acquire the appearance information of the battery under test, including label position information, label peeling, damage, reversed application, missing labels, improper installation of battery accessories, accessory damage, misalignment, and missing traceability codes. When detecting label position information, a corresponding reference system is established on the battery label; for example, the battery casing can be used as a reference system. Figure 2 The positioning line indicates the position and direction of the positioning tag. The battery image is compared with the detected battery tag image by comparing the stored battery image. If the comparison image is within the error range, it is considered qualified; otherwise, it is considered unqualified.

[0044] The illumination unit 30 is set at the detection position. The illumination unit 30 provides a light source for the image acquisition unit 20 to acquire the appearance information of the battery to be tested, ensuring sufficient light during image acquisition.

[0045] Computer terminal 40 is connected to image acquisition unit 20. Computer terminal 40 is used to store the appearance information of qualified batteries and compare it with the appearance information of the battery to be tested acquired by image acquisition unit 20 to determine whether the appearance of the battery surface is qualified.

[0046] The defective product ejection unit 50 ejects batteries with substandard appearance from the conveying track of the conveying unit 10. In this embodiment, the defective product ejection unit 50 can be an electric push rod. In other embodiments, other methods can also be used to achieve the requirement of ejecting batteries with substandard labels from the conveying track of the conveying unit 10.

[0047] A second conveying unit 60 is arranged opposite to the defective product ejection unit 50. The second conveying unit 60 conveys the battery on the conveying track of the ejection conveying unit 10.

[0048] Two sets of limiting mechanisms 80 are set on both sides of the conveying unit 10. The battery passes between the two sets of limiting mechanisms 80. The limiting mechanism 80 completes the operation of limiting the movement trajectory of the battery. The setting of the limiting mechanism 80 reduces the position error during the battery conveying process and improves the accuracy of the battery position during image recognition.

[0049] In the technical solution of this image recognition and monitoring system for battery packaging lines, the battery is placed on the conveying unit 10 and between two sets of limiting mechanisms 80 from the input end (the right side of this device is the input end). (The battery is placed facing the same direction.) Under the limiting action of the limiting mechanism 80, the conveying unit 10 moves the battery to the detection position. The image acquisition unit 20 collects the label information on the surface of the battery to be detected. The lighting unit 30 provides a light source for the image acquisition unit 20. The label information on the surface of the battery to be detected collected by the image acquisition unit 20 is compared with the label information on the surface of qualified batteries stored in the computer terminal 40. Batteries with qualified labels are continued to be conveyed by the conveying unit 10. Batteries with unqualified labels are pushed out of the conveying track of the conveying unit 10 by the defective product ejection unit 50 and sent to the conveying unit 2 60, where the conveying unit 2 60 continues to convey them.

[0050] The installation of an image recognition monitoring system on the battery packaging line can effectively prevent the omission or incorrect installation of battery accessories, including but not limited to plugs, handles, safety valves, photoelectric sensors, and coding devices. It can effectively determine whether the label position is qualified and whether the label is peeling, damaged, reversed, or missing, thereby improving product quality.

[0051] Example 2

[0052] Figure 3 The diagram shown is a top view of the limiting mechanism in this embodiment; Figure 4 The diagram shown is a structural schematic of the top rod in this embodiment; Figure 5 The diagram shown is a structural schematic of the conveyor roller in this embodiment.

[0053] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 3The limiting mechanism 80 includes a roller group consisting of roller 1 81, roller 2 82, and roller 3 83. Roller 1 81 is connected to a driving component, which drives the transmission belt 84 to move as shown in the figure through roller 1 81, roller 2 82, and roller 3 83. Figure 3 The rollers 81, 82, and 83 move in the direction indicated by the middle arrow. The same transmission belt 84 is connected to the outside of the rollers 81, 82, and 83. The outer ring of the transmission belt 84 is provided with a push rod 85.

[0054] The line connecting roller 2 82 and roller 3 83 is set parallel to the side line of conveying unit 10, and the line connecting roller 1 81 and roller 2 82 intersects the side line of conveying unit 10. The distance between the two rollers 1 81 is greater than the distance between the two rollers 2 82.

[0055] The battery is placed on the conveying unit 10, between the two limiting mechanisms 80, and in the area between roller 1 81 and roller 2 82. The area between roller 1 81 and roller 2 82 is configured such that during the conveying process of the battery by the conveying unit 10, the moving push rod 85 contacts the battery that has shifted position and pushes the battery, causing it to gradually move to the middle position of the conveying unit 10. The area between roller 2 82 and roller 3 83 ensures that the passing battery is conveyed forward while remaining parallel to the edge line.

[0056] The limit mechanism 80 is set to adjust and maintain the movement trajectory of the battery, preventing the battery from shifting its position during operation and causing invalid image capture, thereby improving the effectiveness of the image recognition monitoring system for the battery packaging line.

[0057] refer to Figure 3 The limiting mechanism 80 also includes a plate 86, which is disposed inside the transmission belt 84, between roller 1 81 and roller 2 82, and between roller 2 82 and roller 3 83. The plate 86 provides rigid support for the push rod 85, preventing the push rod 85 from failing to push the battery properly due to the deformation capability of the transmission belt 84.

[0058] refer to Figure 3 The inner ring of the transmission belt 84 is provided with a limiting belt 841. Rollers 1, 82 and 3 are provided with annular grooves that match the limiting belt 841. Plate 86 is provided with a strip groove that matches the limiting belt 841. During the rotation of the transmission belt 84, the limiting belt 841 is located inside the annular groove and the strip groove and slides with them. The push rod 85 is set at the position corresponding to the limiting belt 841 to prevent the transmission belt 84 from flipping up and down, and at the same time keep the push rod 85 in a horizontal state to ensure the pushing effect of the push rod 85 on the battery.

[0059] refer to Figure 4 The push rod 85 includes a threaded sleeve 851 connected to the transmission belt 84. A screw 852 is threadedly fitted in the threaded sleeve 851. To increase the contact area with the battery, a block 853 is connected to one end of the screw 852 located outside the threaded sleeve 851. The movable end of the block 853 is set as a rubber end, so that the block 853 and the battery have flexible contact.

[0060] The push rod 85 is composed of a threaded sleeve 851 and a screw 852, which allows the overall length of the push rod 85 to be changed. The overall length can be adjusted according to the specifications of the battery to be tested, which has a wide range of adaptability and high flexibility.

[0061] refer to Figure 2 , Figure 5 The conveying unit 10 includes a frame 11, a conveying roller 12 mounted on the frame 11, and a drive unit that drives the conveying roller 12 to rotate.

[0062] The conveying roller 12 includes a shaft 121, and two ends of the shaft 121 are connected to a shaft 122 that cooperates with the drive component. A sleeve 123 is fitted on the shaft 121 and the shaft 122. A ring 124 extends radially from the inner wall of the sleeve 123 corresponding to the middle of the shaft 121. The ring 124 slides with the shaft 121. A spring 125 is provided between the ring 124 and the shaft 122.

[0063] When the battery moves upward on the axis of the conveying roller 12 under the action of the limiting mechanism 80 and the defective product ejection unit 50, it drives the sleeve 123 to move synchronously under the action of gravity and friction. At this time, the corresponding spring 125 is compressed or stretched. When the battery is removed from the corresponding conveying roller 12, the sleeve 123 is reset under the action of the spring 125.

[0064] The conveying roller 12 is composed of an internal shaft 121 and shaft 122 and an external sleeve 123. While supporting the battery and fulfilling the conveying requirements, the limiting mechanism 80 and the defective product ejection unit 50 push the battery to move in the axial direction of the conveying roller 12, and the sleeve 123 moves at the same time to reduce the friction between the battery shell and the conveying roller 12 and reduce the wear of the battery shell.

[0065] refer to Figure 5 A groove 127 is provided on the shaft 122. A rod 126 is provided on the sleeve 123 corresponding to the inner wall of the groove 127. The rod 126 provides a support point for the sleeve 123 and improves the load-bearing capacity of the sleeve 123. At the same time, in order to reduce the friction between the rod 126 and the groove 127, a roller is provided at one end of the rod 126 and inserted into the inside of the groove 127. The roller makes rolling contact with the groove 127.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
