Description

Technical Field

[0001] The utility model belongs to the field of machine vision detection, and in particular relates to a high-speed online detection device for cylindrical battery filling defects. Background Art

[0002] As common cylindrical batteries, No. 5 and No. 7 batteries play an indispensable role in many small appliances and digital products due to their small size and moderate capacity, and are widely used in civilian and military fields.

[0003] As an important part of the traditional manufacturing industry, batteries are prone to some quality problems. During the production and preparation of batteries, especially on high-speed production lines, defects may occur in the positive and negative electrodes of the battery due to factors such as processing accuracy, equipment wear and human operation. In order to ensure product quality and production efficiency, each battery must be accurately defect-detected. Defect detection is not only a key step in determining whether a battery is a qualified product, but is also directly related to the arrangement of subsequent processing procedures. For batteries that fail the inspection, rework, reprocessing or scrapping may be required. Therefore, defect detection of produced batteries is an indispensable task for enterprises. At the same time, online detection of the positive and negative electrodes of batteries during the production process is of great significance for improving product quality, reducing scrap rates and optimizing production processes.

[0004] In the existing methods, the measurement of battery filling defects is mostly manual inspection. However, traditional manual inspection methods can no longer meet the needs of modern production lines. Manual inspection is not only time-consuming, labor-intensive, and costly, but also inefficient and prone to missed inspections. In the face of high-speed and efficient automated production lines, a new method that can replace manual inspection is urgently needed. The emergence of machine vision technology provides a solution to this problem. The principle of machine vision filling defect detection is to convert the target to be detected into an image signal through a CCD camera, and then transmit it to a dedicated image processing system. This system converts it into a digital signal based on information such as pixel distribution, brightness, and color, and extracts the defect characteristics of the target through various existing algorithm operations. According to the preset tolerance and other conditions, the system can automatically judge and output the results, including bruises, scratches, contamination, etc., to achieve automatic recognition function. However, the prior art mostly adopts multiple disc devices to produce batteries, the inspection disc completes the defect detection of the battery in the inspection area, and transfers the battery to the rejection disc, the rejection rod on the rejection disc rejects the defective battery to the defective disc, the defective disc guides the defective battery to the defective recovery basket, and the non-defective battery is guided by the rejection disc to the collection disc through the guide device. The disadvantage of this scheme is that the mechanical structure is complicated, and multiple discs are required to respectively undertake the tasks of detection, diversion, rejection, and collection, and multiple guide devices are required to undertake the diversion work between the discs, and the installation and maintenance costs are high.

[0005] Therefore, it is of great significance to propose an online detection device with simple structure, low cost, strong practicality and high speed requirements for the filling defect detection of cylindrical batteries such as No. 5 batteries and No. 7 batteries. Summary of the invention

[0038] In a specific embodiment of the utility model, preferably, the inductive proximity switch sensor 3-3 includes three parts: an oscillator, a switching circuit and an amplifying output circuit; when the sensor is working, the oscillator generates a variable alternating magnetic field, and when the metal shell of the battery reaches the sensing distance, eddy currents are generated in the metal, thereby causing the oscillation to attenuate or stop; the changes in the oscillation attenuation and stop of the oscillator are processed by the post-amplifying circuit and converted into a switching signal, thereby achieving non-contact identification of the battery to control a high-speed camera aimed at the upper end face of the battery filling to trigger taking pictures.

[0041] Figure 5 The figure shows an implementation mode of the battery magnetic attraction device 4, wherein the battery magnetic attraction device 4 comprises an electromagnet controller 4-1, a semicircular magnetic battery slot 4-2 and an electromagnet 4-3; the semicircular magnetic battery slot 4-2 is located on the conveyor belt 1-1 of the conveying device 1, with the semicircular opening facing outward, the electromagnet 4-3 is arranged on the inner wall of the semicircular magnetic battery slot 4-2, and the electromagnet controller 4-1 is respectively connected to the electromagnet 4-3 and the main control system.

[0042] The height of the semicircular magnetic battery slot 4 - 2 is uniform, and the battery 6 to be tested is adsorbed on the semicircular magnetic battery slot 4 - 2 to ensure uniform height.

[0043] The battery conveying device 1 is driven by the motor 2-1 in the conveying drive device 2, and the conveyor belt 1-1 runs along the battery production line. Several semicircular magnetic battery slots 4-2 are arranged on the outer edge of the conveyor belt 1-1, and electromagnets 4-3 are arranged inside to attract batteries; the conveying drive device 2 is installed on the inner side of the conveying device 1, and the conveying drive device 2 drives the conveyor belt 1-1 to run through gears.

[0044] The battery 6 to be tested is adsorbed in the semicircular magnetic battery slot 4-2 by the electromagnet 4-3. The electromagnet controller 4-1 is provided with a code and stored in the main control system. When the high-speed visual inspection device 3 detects that the battery in the semicircular magnetic battery slot 4-2 is defective and sends a signal to the main control system, the main control system sends a rejection instruction to the electromagnet controller 4-1 with the corresponding code of the semicircular magnetic battery slot 4-2. The corresponding electromagnet controller 4-1 receives the rejection instruction issued by the main control system and controls the electromagnet 4-3 to demagnetize, so that the unqualified battery immediately leaves the semicircular magnetic battery slot 4-2 and falls into the defective battery recovery tray 5 below the recovery area of ​​the conveyor belt 1-1.

[0045] The utility model adopts the conveyor belt 1-1 with a semicircular magnetic battery slot 4-2, which not only provides higher stability, but also ensures fast and stable working efficiency. Specifically, the conveying mechanism of the conveyor belt 1-1 with a semicircular magnetic battery slot 4-2 enables the battery to move smoothly and orderly during the detection process, avoiding detection errors or production interruptions caused by unstable transmission.

[0046] The utility model has a conveyor with a semicircular magnetic battery slot 4-2, which realizes stable fixation of the battery and facilitates the staff to observe the operation status of the production line. The high-speed visual inspection device 3 is located on one side of the conveyor 1, and the high-speed cameras thereon are installed above and below the inspection area of ​​the conveyor 1. The height is adjusted according to the focal plane of the camera, and a high-speed camera is aimed at the negative electrode of the battery. This design not only simplifies the structure of the device and reduces the cost, but also greatly improves the inspection efficiency.

[0047] Figure 6 An embodiment of the defective battery recovery tray 5 is shown.

[0048] Figure 7 The figure shows a presentation style of the battery 6 to be tested.

[0049] The main control system is connected to the driving device 2, the high-speed visual inspection device 3 and the battery magnetic device 4 respectively; the main control system receives the battery image transmitted by the high-speed visual inspection device 3 and determines whether there are defects. If the battery has defects, the battery magnetic device 4 is controlled to guide the unqualified battery into the defective tray 5. If the battery does not have defects, it is transported to the next processing area by the conveying device 1.

[0050] According to this embodiment, preferably, the annular light source 3-2 uses a blue annular light source with diffuse reflective glass material to supplement the negative electrode of the battery. The high-speed camera 3-1 uses a high-speed color CCD camera. The annular light source is coaxially placed with the lens of the high-speed color CCD camera, aligned with the edge of the telecentric lens, and adjusted to a suitable distance from the battery to effectively reduce shadows and improve the contrast of the defect feature to be measured; the use of a blue annular light source is most effective in detecting defects on the surface of highly reflective materials; therefore, the use of a blue annular light source is very suitable for battery filling defect measurement. At the same time, by image color gain and increasing the camera aperture, reducing the exposure time can effectively alleviate the motion blur generated when taking pictures. According to this embodiment, preferably, the exposure time of the high-speed camera 3-1 is 60 microseconds.

[0051] The inductive proximity switch sensor 3-3 is used to identify the approaching battery signal and transmit it to the amplifying output circuit, converting the battery signal into a switch signal and transmitting it to the main control system. The main control system controls the high-speed camera 3-1 at the negative end of the battery to trigger a photo.

[0052] The detection method of the cylindrical battery filling defect high-speed online detection device based on vision comprises the following steps: the battery 6 to be tested completes the previous process, passes through the semicircular magnetic battery slot 4-2 on the conveyor belt 1-1, and after being adsorbed, it is recognized when it is close to the inductive proximity switch sensor 3-3 as the conveyor belt 1-1 runs at high speed. At the same time, when passing through the high-speed visual detection device 3, the high-speed camera 3-1 recognizes the battery, triggers the photo, and transmits the negative electrode filling picture taken to the main control system; the main control system performs cylindrical battery filling defect detection on the battery negative electrode filling picture based on the principle of existing machine vision filling defect detection. If the detection is unqualified, the main control system controls the electromagnet controller 4-1 of the battery magnetic device 4 to cut off the power supply of the electromagnet 4-3 on the semicircular magnetic battery slot 4-2, so that the defective battery is separated from the semicircular magnetic battery slot 4-2 and falls into the defective battery recovery tray 5; if the detection is qualified, the conveyor belt 1-1 continues to convey the qualified battery to the next processing area.

[0053] The 1-1 rotating design of the conveyor belt adopted in the utility model not only provides higher stability, but also ensures fast and stable working efficiency. Specifically, the magnetic transmission mechanism enables the battery to move smoothly and orderly during the detection process, avoiding detection errors or production interruptions caused by unstable transmission.

[0054] The utility model adopts electromagnet 4-3 adsorption to achieve stable fixation of the battery and ensure that the negative electrode of the battery is completely exposed in the camera imaging focal plane. This design not only simplifies the structure of the device and reduces the cost, but also greatly improves the detection efficiency.

[0055] The utility model can realize rapid detection of battery defects, has extremely high detection speed and practicability, and greatly improves measurement efficiency.

[0056] The utility model adopts the visual inspection means of the existing technology, combined with the assembly line operation mode, to achieve rapid detection of battery filling defects. The entire system integrates multiple stations such as battery detection and rejection and collection, and rejects defective products by controlling the electromagnet to ensure the effective separation and collection of defective and finished batteries. The highly integrated design of the utility model not only improves the detection efficiency, but also greatly simplifies the operation process. The battery ensures the stability and low failure rate of the structure by combining the magnetic suction device and the conveyor belt transmission. At the same time, it is also equipped with a battery limit device-a semi-circular magnetic suction battery notch 4-2, so that the battery can be arranged horizontally and neatly, which is convenient for the visual system to detect and identify. The electromagnetic on-off control of the rejection of defective batteries in the transmission and defective separation process ensures the high stability and high efficiency of repeated operations. The entire working process is highly intelligent and does not require human intervention. It not only reduces labor costs, but also improves work efficiency, which is in line with the green and environmentally friendly production concept.
