Abstract
Description
Technical Field
[0001] This invention relates to the technical field of mechanical manufacturing, and in particular to a method, device, equipment and medium for controlling the flaring of a tube expander. Background Technology
[0002] With the rapid development of technology, tube expander technology has gradually been widely applied. Among the many types of tube expanders, the horizontal tube expander is favored due to its unique advantages. This type of machine generally adopts a separate working method for tube expansion and flaring, that is, the two tubes are expanded first, and then flaring is performed. However, in actual operation, the expanded copper tubes of the two tubes often have inconsistent heights, which directly leads to some tube ends not being effectively flared. If the flaring depth is blindly increased, it is very easy to cause cracking of other tube ends, thus causing a series of subsequent problems. In the existing technology, the two tubes often need to be manually expanded, and in some cases, the entire two tubes may be scrapped due to flaring problems. This series of problems not only significantly increases labor costs, but also significantly increases the material scrap rate, posing a serious challenge to production efficiency and cost control. Summary of the Invention
[0003] This invention provides a method, apparatus, equipment, and medium for controlling the flaring of a tube expander, aiming to solve the problem that existing tube expanders cannot perform flaring efficiently and accurately.
[0004] In a first aspect, embodiments of the present invention provide a flaring control method for a tube expander. When applied to an equipment controller, the method includes: generating flaring parameters based on the workpiece to be flared; flaring a plurality of tube openings in the workpiece according to the flaring parameters; if flaring adjustment information is received from a vision processing terminal, adjusting the flaring parameters according to the flaring adjustment information; and controlling the tube expander to flare the workpiece according to the adjusted flaring parameters.
[0005] Secondly, embodiments of the present invention also provide a flaring control device for a tube expander. When the method is applied to a vision processing end, it includes: acquiring an image of the tube opening of a flared workpiece; performing image recognition on the tube opening image to determine whether an abnormal tube opening appears in the tube opening of the flared workpiece; if so, performing flaring analysis on the abnormal tube opening to generate corresponding flaring adjustment information; and sending the flaring adjustment information to the equipment controller.
[0006] Thirdly, embodiments of the present invention also provide a flaring control device for a tube expander, which includes a unit for performing the method as described in any of the first aspects, or includes a unit for performing the method as described in any of the second aspects.
[0007] Fourthly, embodiments of the present invention also provide a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described method.
[0008] Fifthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, the computer program including program instructions that, when executed by a processor, can implement the above-described method.
[0009] This invention provides a flaring control method, apparatus, equipment, and medium for a tube expander. When applied to an equipment controller, flaring parameters are generated based on the workpiece to be flared, and several ends of the workpiece are flared according to these parameters. If flaring adjustment information is received from a vision processing unit, the flaring parameters are adjusted according to the adjustment information. The tube expander is then controlled to flare the workpiece according to the adjusted flaring parameters. When applied to a vision processing unit, the method acquires images of the flared ends of the workpiece, performs image recognition on the images to determine if any abnormal ends are present. If abnormal ends are found, flaring analysis is performed on the abnormal ends to generate corresponding flaring adjustment information. This flaring adjustment information is then sent to the equipment controller. In this embodiment of the invention, a device controller controls a tube expander to expand the workpiece to be expanded. A vision processing unit acquires images of the expanded workpiece's opening and analyzes these images to determine if any anomalies have occurred during the expanding process. This analysis assesses whether the current expanding parameters are sufficient for accurate expanding. If an anomaly occurs, it indicates that the current parameters are insufficient for accurate expanding. Therefore, the abnormal opening is analyzed to generate corresponding expanding adjustment information. This information allows the device controller to control the tube expander to expand subsequent workpieces to be expanded. By enabling data interaction between the vision processing unit and the device controller, the time cost of manual identification and adjustment is reduced, and the equipment scrap rate is effectively decreased, thereby achieving accurate expanding of the workpiece to be expanded.

[0025] Please see Figure 1 , Figure 1 This is a flowchart illustrating the flaring control method for a tube expander provided in this embodiment of the invention. The flaring control method for the tube expander in this embodiment can be applied to workpieces requiring tube expansion and flaring, such as the two components of an air conditioner (condenser and evaporator). The equipment controller controls the tube expander to perform tube expansion and flaring, and a vision processing unit uses a camera to capture images of the flared workpiece tube opening and determines whether any abnormalities have occurred. For example, if insufficient flaring is detected, the equipment controller controls a supplementary flaring device to perform supplementary flaring. Using this method reduces labor costs and improves the equipment's yield rate.
[0026] Figure 1 This is a schematic diagram of the process of applying the tube expander flaring control method provided in this embodiment of the invention to the equipment controller. As shown in the figure, the method includes the following steps S110-S130.
[0027] S110. Generate flaring parameters based on the workpiece to be flared, and flare several pipe openings in the workpiece according to the flaring parameters.
[0028] In this embodiment, the workpiece to be flared is a workpiece that needs to be expanded and flared using a tube expander, such as the condenser and evaporator in an air conditioning unit. The tube expander flares and flares the copper tubes of the two units, causing them to expand and harden, facilitating subsequent processing steps such as extraction or bending. Flaring mainly enlarges the ends of the copper tubes, making it easier to add parts and weld them in later processes. Flaring parameters are generated based on the workpiece to be flared. Specifically, the equipment controller performs a detailed analysis of the workpiece, including its material, wall thickness, tube diameter, and the required shape and size after flaring. Flaring parameters are generated based on the analysis results, or they can be directly generated based on preset workpiece requirements. These flaring parameters are the parameters required for flaring the workpiece, including flaring diameter, flaring depth, and flaring speed. The equipment controller controls the tube expander to flare several ends of the workpiece to be flared according to the generated flaring parameters. By flaring several ends of the workpiece according to the flaring parameters, the workpiece to be flared is precisely flared.
[0029] In one embodiment, such as Figure 2 As shown, step S110 is followed by steps S1101-S1102.
[0030] S1101. Determine whether the signal to be amplified sent by the vision processing terminal has been received;
[0031] S1102. If received, the expanded pipe opening at the expansion position is expanded according to the expansion depth, wherein the expansion signal carries the expansion depth and the expansion position.
[0032] In this embodiment, the signal to be expanded is generated when the tube expander fails to expand the tube opening sufficiently. For example, if the target expansion diameter is 4.5mm, but the expanded diameter is only 4mm, it indicates that the tube opening expansion was unsuccessful and requires further expansion. It is understood that a workpiece to be expanded may have multiple tube openings. Normally, the tube opening diameters are consistent and within the allowable range of the process requirements. However, there may still be a small number of tube openings with diameters different from the required dimensions, resulting in insufficient expansion of some tube openings, thus requiring further expansion. If the signal to be expanded is received from the vision processing terminal, the expanded tube openings are expanded according to the expansion depth and expansion position in the expansion signal. The tube openings requiring further expansion are determined based on the expansion position, and the equipment controller controls the expansion device to expand them according to the expansion depth. By receiving the expansion signal sent by the vision processing terminal, the pipe ends that have been expanded but not successfully expanded are expanded to ensure that all pipe ends in the workpiece to be expanded are expanded in place, thereby improving the expansion quality of the workpiece to be expanded.
[0033] S120. If the flare adjustment information sent by the vision processing terminal is received, the flare parameters are adjusted according to the flare adjustment information.
[0034] In this embodiment, after the flaring is completed, the device controller sends a flaring completion signal to the vision processing terminal and determines whether it receives flaring adjustment information from the vision processing terminal within a preset time. For example, it determines whether it receives flaring adjustment information from the vision processing terminal after 20 minutes of flaring. If it does not receive such information, or if it receives information to continue flaring, it continues to flare several pipe ends in the workpiece to be flared according to the generated flaring parameters. If it receives flaring adjustment information from the vision processing terminal, it parses the received information to determine the flaring parameters that need to be adjusted. This may include adjustments to the flaring diameter, flaring angle, flaring depth, flaring position, etc. Based on the parsed adjustment information, the corresponding flaring parameters are adjusted. For example, increasing or decreasing the flaring diameter, adjusting the flaring angle, changing the flaring depth, fine-tuning the flaring position, etc. It should be noted that the flaring adjustment information will be received when the pipe end breaks during flaring. By adjusting the flaring parameters according to the flaring adjustment information, the flaring parameters are reasonably adjusted and the adjustment measures are strictly implemented, thereby ensuring the stability and reliability of flaring and improving the quality and efficiency of flaring.
[0035] S130. Control the tube expander to expand the workpiece to be expanded according to the adjusted flaring parameters.
[0036] In this embodiment, the equipment controller controls the tube expander to expand the tube according to the adjusted flaring parameters. Specifically, the expanded tube expander expands workpieces that have not yet been expanded, according to the adjusted flaring parameters. It is important to note that if the tube expander causes the tube end to break during flaring, it will receive flaring adjustment information. This indicates that the expanded workpiece has broken and is transferred to the next processing station. Therefore, the adjusted flaring parameters are used when expanding other workpieces. By expanding the workpiece according to the adjusted flaring parameters, the flaring process is continuously optimized, thereby ensuring the stability and reliability of the flaring process and improving its quality and efficiency.
[0037] Figure 3 This is a flowchart illustrating the application of the tube expander flaring control method provided in this embodiment of the invention to a vision processing end. As shown in the figure, the method includes the following steps S210-S230.
[0038] S210. Acquire an image of the flared workpiece's pipe opening, and perform image recognition on the pipe opening image to determine whether there is an abnormal pipe opening in the flared workpiece's pipe opening.
[0039] In this embodiment, the vision processing end acquires images of the workpiece after it has been flared by the tube expander using a camera. The vision processing end then performs image recognition on the tube opening image. Specifically, the vision processing end preprocesses the acquired tube opening image, including steps such as noise reduction, contrast enhancement, and grayscale conversion, to improve image quality and provide more favorable conditions for subsequent image recognition. It then extracts key features, such as edge contours and tube diameter, from the preprocessed tube opening image using image processing algorithms. Based on these extracted key features, it determines whether there are any abnormal tube openings in the flared workpiece. For example, if a broken tube opening is shown in the image, an abnormal tube opening can be identified. The specific method for image recognition of the tube opening image is not limited, as long as it can effectively identify the image. By acquiring images of the flared workpiece's tube opening, it determines whether there are any abnormal tube openings in the flared workpiece, thus identifying any abnormalities in the flaring process performed by the tube expander, allowing for timely adjustment of flaring parameters or timely supplementary flaring.
[0040] In one embodiment, such as Figure 4 As shown, step S210 includes steps S211-S213.
[0041] S211. Perform image recognition on the pipe opening image to obtain the pipe opening diameter of each pipe opening and compare it with the target pipe opening diameter;
[0042] S212. If there is a pipe opening with a diameter smaller than the target pipe opening, then the pipe opening is determined to be an abnormally flared pipe opening.
[0043] S213. If there is a pipe opening with a diameter larger than the target pipe opening and a gap, then the pipe opening is determined to be a ruptured abnormal pipe opening.
[0044] In this embodiment, the target pipe diameter is the standard pipe size transmitted from the device controller to the vision processing end, wherein the standard pipe size can be determined according to specific process requirements. Image recognition is performed on the pipe image; specifically, the acquired pipe image can be input into a pre-trained image recognition system. This system can be an image recognition model based on deep learning (such as a convolutional neural network CNN), which can automatically identify and extract key features from the image, including the edges and contours of the pipe, and can accurately measure the diameter of each pipe. The specific method for image recognition is not limited, as long as accurate diameters and images of each pipe are obtained. The diameter of each pipe is compared with the target pipe diameter. If the comparison shows that there is a pipe with a diameter smaller than the target pipe diameter, then these pipes are determined to be abnormally flared pipes. If the diameter of a pipe is larger than the target pipe diameter, and image recognition confirms that there is a gap or crack in the pipe, then these pipes are determined to be abnormally broken pipes. By performing image recognition on the pipe opening images, obtaining the pipe opening diameter of each opening and comparing it with the target pipe opening diameter, abnormal pipe openings can be identified. This can improve production efficiency, reduce the cost and error of manual inspection, and provide strong data support for subsequent process improvement and quality control.
[0045] S220. If an abnormal port is found, an flaring analysis is performed on the abnormal port to generate corresponding flaring adjustment information.
[0046] In this embodiment, if the vision processing terminal detects the abnormal pipe opening, it performs a flaring analysis on the abnormal pipe opening. Specifically, it performs detailed problem localization on the identified abnormal pipe opening. This includes determining the type of abnormal pipe opening (e.g., insufficient flaring, crack, etc.) and the specific location and severity of the abnormality (e.g., diameter deviation, gap size, etc.). Corresponding flaring adjustment information is generated for the specific problem of the abnormal pipe opening. Specifically, for a cracked pipe opening, the flaring parameters that need adjustment are determined based on its diameter after the crack, and flaring adjustment information is generated based on these parameters. By performing flaring analysis on abnormal pipe openings and generating corresponding flaring adjustment information, quality problems in the production process can be effectively solved, improving product quality and production efficiency. This process requires the comprehensive application of professional knowledge, data analysis capabilities, and practical experience to ensure the accuracy and effectiveness of the adjustment measures.
[0047] In one embodiment, such as Figure 5 As shown, step S220 includes steps S221-S222.
[0048] S221. If the abnormal pipe opening is a ruptured abnormal pipe opening, the diameter of the ruptured abnormal pipe opening is compared with the diameter of the target pipe opening to obtain the difference in rupture diameter.
[0049] S222. Generate flaring adjustment information with new flaring parameters based on the preset diameter-to-depth ratio between the pipe diameter and the flaring depth and the difference in the rupture diameter.
[0050] In this embodiment, if the abnormal pipe opening is a ruptured abnormal pipe opening, i.e., a pipe opening ruptured due to a large flaring depth, the diameter of the ruptured abnormal pipe opening is compared with the target pipe opening diameter to obtain the difference between the actual diameter of the ruptured abnormal pipe opening and the target diameter. This difference reflects the degree of deviation of the ruptured abnormal pipe opening in terms of diameter. Flaring adjustment information with new flaring parameters is generated based on a preset diameter-to-depth ratio between the pipe opening diameter and the flaring depth. The preset diameter-to-depth ratio can be determined according to the specific flaring workpiece and production target. The flaring depth is directly proportional to the pipe opening diameter; for every 1mm increase in flaring depth, the pipe opening size increases by a corresponding value according to the preset diameter-to-depth ratio. Therefore, flaring adjustment information with new flaring parameters can be generated based on the preset diameter-to-depth ratio and the difference in ruptured diameter. Specifically, the value by which the flaring depth needs to be reduced can be determined based on the difference in ruptured diameter and the flaring ratio, thereby generating the flaring adjustment information according to the required reduction in flaring depth. By calculating the difference in rupture diameter and using a preset diameter-to-depth ratio, flaring adjustment information with new flaring parameters is generated. This combines production experience and data analysis to ensure that the quality of the adjusted pipe end meets the standards, while improving production efficiency and product quality.
[0051] In one embodiment, such as Figure 6 As shown, step S220 further includes steps S223-S226.
[0052] S223. If the abnormal pipe opening is a flared abnormal pipe opening, then obtain the difference between the pipe opening diameter of the flared abnormal pipe opening and the flared diameter of the target pipe opening.
[0053] S224. Determine the expansion depth when expanding the abnormal flared pipe opening based on the ratio of the flared diameter difference to the preset diameter depth;
[0054] S225. Determine the re-expansion position of the abnormal flaring port based on the preset initial port position and the preset distance between the ports;
[0055] S226. Generate a signal to be expanded based on the expansion position and the expansion depth, and send it to the device controller.
[0056] In this embodiment, the abnormal pipe opening is a flared abnormal pipe opening, i.e., a pipe opening with insufficient flaring. The difference in flaring diameter between the current pipe opening diameter and the target pipe opening diameter is calculated. It should be noted that the abnormality is due to insufficient flaring, so the diameter of the flared abnormal pipe opening should be smaller than the target pipe opening diameter. The supplementary flaring depth is determined based on the ratio of the flaring diameter difference to a preset diameter-depth ratio. For example, assuming a preset diameter-depth ratio of 1:0.5, meaning that for every unit increase in diameter, 0.5 units of depth are required. If the flaring diameter difference is 2 units, then the supplementary flaring depth should be increased by 1 unit from the original flaring depth. The location for re-expansion of the abnormally flared pipe opening is determined based on the preset initial pipe opening position and the preset distance between the pipe openings. The distance between the pipe openings is usually fixed; assuming a distance of 10 cm, and the distance between the re-expansion device at its initial position and the first pipe opening is measured on-site (assumed to be 11 cm), if the 6th pipe opening needs re-expansion, the distance the re-expansion device needs to travel is: 11 + 10 * (6 - 1) (re-expansion location). Here, the preset initial pipe opening position is the distance between the re-expansion device at its initial position and the first pipe opening. Finally, a re-expansion signal is generated based on the determined re-expansion location and re-expansion depth, and this signal is sent to the equipment controller. The equipment controller receives this signal and controls the relevant re-expansion device to perform the re-expansion operation. By generating the re-expansion signal based on the re-expansion location and re-expansion depth, the abnormally flared pipe opening is accurately re-expanded, ensuring its diameter meets production requirements.
[0057] In one embodiment, such as Figure 7 As shown, step S226 further includes steps S2261-S2262.
[0058] S2261. After the abnormal flaring of the pipe is completed, determine whether the flared pipe is still an abnormal flaring pipe.
[0059] S2262, If so, an abnormal alarm signal will be generated.
[0060] In this embodiment, after the equipment controller controls the expansion device to expand the abnormally flared pipe opening, the vision processing terminal re-captures the pipe opening image to determine whether the expanded pipe opening is still an abnormally flared opening. The specific judgment steps are not detailed here. If, after inspection, the expanded pipe opening is still found to be abnormal, meaning its diameter still does not meet the target pipe opening diameter requirement, then the expansion device is malfunctioning. For example, the flaring tool on the expansion device may not be installed, making it impossible to correct the pipe opening. Therefore, an abnormal alarm signal needs to be generated. This alarm signal can be a simple indicator light flashing, a buzzer alarm, or a more complex electronic signal used to trigger a production line shutdown, mark the abnormal pipe opening, or notify operators. By generating an abnormal alarm signal based on whether the expanded pipe opening is still abnormally flared, relevant personnel can be notified in a timely manner so that they can take further measures to handle the abnormally flared pipe opening, preventing it from flowing into the next process or the final product, thereby ensuring product quality and production efficiency.
[0061] S230, The flare adjustment information is sent to the device controller.
[0062] In this embodiment, the flaring adjustment information refers to the information generated when the pipe end breaks, which adjusts the flaring parameters. For example, the information includes, but is not limited to, information on flaring depth adjustment. The flaring adjustment information is sent to the equipment controller, for example, via wired communication (such as Ethernet, RS-485, etc.) and wireless communication (such as Wi-Fi, Bluetooth, etc.). The specific communication method chosen depends on the production line layout, equipment type, and communication requirements. By sending the flaring adjustment information to the equipment controller, the equipment controller can produce flared workpieces that meet production requirements based on the flaring adjustment information, thereby improving product quality and production efficiency.
[0063] Corresponding to the above-described tube expander flaring control method, the present invention also provides a tube expander flaring control device. This tube expander flaring control device includes a unit for executing the above-described tube expander flaring control method, and the device can be configured in a desktop computer, tablet computer, laptop computer, or other terminal.

[0072] The acquisition unit 410 is used to acquire images of the flared workpiece's nozzle, and to perform image recognition on the nozzle images to determine whether there are any abnormal nozzles in the flared workpiece's nozzle.
