Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and in particular to a method, device, equipment and medium for controlling the expansion of a tube expander. Background Art

[0002] With the rapid development of science and technology, tube expander technology has gradually been widely used. Among the many types of tube expanders, horizontal tube expanders are favored because of their unique advantages. This type of machine generally adopts a working mode that separates tube expansion and mouth expansion, that is, the two devices are expanded first, and then the mouth expansion is carried out. However, in actual operation, the expanded copper tubes of the two devices often have the problem of height inconsistency, which directly leads to the failure of some pipe openings to be effectively expanded. If the expansion depth is increased blindly, it is very easy to cause the expansion and cracking of another part of the pipe opening, which leads to a series of subsequent problems. The two devices in the existing technology often need to rely on manual expansion operations, and in some cases, the entire two devices may be scrapped due to the expansion problem. This series of problems not only greatly increases labor costs, but also significantly increases the scrap rate of materials, posing a severe challenge to production efficiency and cost control. Summary of the invention

[0003] The embodiments of the present invention provide a method, device, equipment and medium for controlling the expansion of a tube expander, aiming to solve the problem that the tube expander in the prior art cannot expand the tube efficiently and accurately.

[0009] The embodiment of the present invention provides a method, device, equipment and medium for controlling the expansion of a tube expander. When applied to the device controller, the expansion parameters are generated according to the workpiece to be expanded, and the expansion parameters are expanded for several tube openings in the workpiece to be expanded according to the expansion parameters; if the expansion adjustment information sent by the visual processing end is received, the expansion parameters are adjusted according to the expansion adjustment information; the tube expander is controlled to expand the workpiece to be expanded according to the adjusted expansion parameters; when the method is applied to the visual processing end, the tube opening image of the expanded workpiece is collected, and the tube opening image is subjected to image recognition to determine whether an abnormal tube opening appears in the tube opening of the expanded workpiece; if an abnormal tube opening appears, the expansion analysis is performed on the abnormal tube opening to generate corresponding expansion adjustment information; and the expansion adjustment information is sent to the device controller. The embodiment of the present invention controls the tube expander to expand the workpiece to be expanded through the device controller, and the visual processing end collects images of the expanded workpiece's tube mouth, and analyzes whether there is an abnormality in the expanding process based on the collected image, so as to determine whether the current expanding parameters can accurately expand the workpiece. If so, it means that the current expanding parameters cannot accurately expand, so the expansion analysis of the abnormal tube mouth is performed to generate corresponding expansion adjustment information, so that the device controller can control the tube expander to expand the subsequent workpiece to be expanded according to the expansion adjustment information. Data interaction between the visual processing device and the device controller can reduce the time cost of manual identification and adjustment, and can effectively reduce the equipment scrap rate, thereby achieving accurate expansion of the workpiece to be expanded.

[0025] See also Figure 1 , Figure 1 A flow chart of a method for controlling the expansion of a tube expander provided in an embodiment of the present invention. The method for controlling the expansion of a tube expander in this embodiment can be applied to workpieces that need to be expanded and expanded, for example, two devices (condenser and evaporator) of an air conditioner. The tube expander is controlled by a device controller to expand and expand, and the visual processing end collects the image of the expanded workpiece tube mouth through a camera device, and determines whether the expansion is abnormal. For example, if the expansion is not fully expanded, the device controller controls the supplementary expansion device to supplement the expansion of the tube mouth. By adopting the method of the present invention, labor costs can be reduced and the qualification rate of the equipment can be improved.

[0026] Figure 1 The following is a flow chart of the expansion control method of the tube expander provided by the embodiment of the present invention applied to the device controller. As shown in the figure, the method includes the following steps S110-S130.

[0027] S110, generating expansion parameters according to the workpiece to be expanded, and expanding a plurality of pipe openings in the workpiece to be expanded according to the expansion parameters.

[0028] In this embodiment, the workpiece to be expanded is a workpiece that needs to be expanded and expanded by a tube expander, for example, the condenser and evaporator in the air conditioning equipment, which are expanded and expanded by the tube expander so that the copper tubes of the two devices expand, thereby hardening the two devices to facilitate the subsequent processing steps to extract the two devices or bend, etc., and the expansion is mainly to expand the copper tube openings of the two devices to facilitate the subsequent process of adding parts for welding. The expansion parameters are generated according to the workpiece to be expanded. Specifically, the equipment controller performs a detailed analysis of the workpiece to be expanded, including its material, wall thickness, pipe diameter, and shape and size requirements after expansion, and generates the expansion parameters according to the analysis results, or directly generates the expansion parameters according to the preset workpiece requirements, wherein the expansion parameters are the parameters required when expanding the workpiece to be expanded, and the expansion parameters include expansion diameter, expansion depth, expansion speed and other parameters. The equipment controller controls the tube expander to expand several pipe openings in the workpiece to be expanded according to the generated expansion parameters. By expanding several pipe openings in the workpiece to be expanded according to the expansion parameters, the workpiece to be expanded can be accurately expanded.

[0029] In one embodiment, if Figure 2 As shown, the step S110 further includes steps S1101 - S1102 .

[0030] S1101, determining whether a signal to be supplemented and expanded sent by the visual processing end is received;

[0031] S1102: If received, supplementary expansion is performed on the expanded pipe opening at the supplementary expansion position according to the supplementary expansion depth, wherein the signal to be supplementary expanded carries the supplementary expansion depth and the supplementary expansion position.

[0032] In this embodiment, the signal to be supplemented is a signal generated when the tube expander does not sufficiently expand the tube orifice. For example, the target expansion diameter should be 4.5 mm, but the diameter of the expanded tube orifice is only 4 mm, which means that the expansion of the tube orifice is unsuccessful, and it needs to be supplemented. It can be understood that there are multiple tube orifices in a workpiece to be expanded. Under normal circumstances, the diameters of the tube orifices are consistent and within the range allowed by the process requirements, but there may still be a small number of tube orifice diameters that are different from the size required by the process. Therefore, some tube orifices are not sufficiently expanded, so they need to be supplemented. If the signal to be supplemented sent by the visual processing end is received, the expanded tube orifice is supplemented according to the supplementary expansion depth and the supplementary expansion position in the supplementary expansion signal. The tube orifice that needs to be supplemented in the expanded tube orifice is determined according to the supplementary expansion position, and the equipment controller controls the supplementary expansion device to supplement it according to the expansion depth. By receiving the signal to be expanded sent by the visual processing end, the expanded but unsuccessful pipe openings are expanded to ensure that all pipe openings 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 expansion adjustment information sent by the visual processing end is received, the expansion parameters are adjusted according to the expansion adjustment information.

[0034] In this embodiment, the device controller sends a flaring completion signal to the visual processing end after the flaring is completed, and determines whether the flaring adjustment information sent by the visual processing end is received within a preset time. For example, it determines whether the flaring adjustment information sent by the visual processing end is received after 20 minutes of flaring. If it is not received, or the information of continuing flaring is received, the flaring of several pipe openings in the workpiece to be flared is continued according to the generated flaring parameters. If the flaring adjustment information sent by the visual processing end is received, the received information is parsed to clarify the flaring parameters that need to be adjusted. This may include adjustments in flaring diameter, flaring angle, flaring depth, flaring position, etc. According to the parsed adjustment information, the corresponding flaring parameters are adjusted. For example, increase or decrease the flaring diameter, adjust the flaring angle, change the flaring depth, fine-tune the flaring position and other parameters. Among them, it should be noted that the flaring adjustment information will be received when the flaring of the pipe opening is broken. 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 the flaring and improving the quality and efficiency of the flaring.

[0035] S130, controlling the tube expander to expand the workpiece to be expanded according to the adjusted expanding parameters.

[0036] In this embodiment, the equipment controller controls the tube expander to expand according to the adjusted expanding parameters, specifically, expands the workpiece to be expanded that has not been expanded according to the adjusted expanding parameters. It should be noted that when the tube expander expands the tube mouth and causes the tube mouth of the workpiece to rupture, it will receive the expansion adjustment information, that is, the expanded workpiece has been ruptured at this time, and it will be transferred to the next station for processing. Therefore, the adjusted expansion parameters are the parameters used when expanding other workpieces to be expanded. By expanding the workpiece to be expanded according to the adjusted expansion parameters, the expansion process is continuously optimized, thereby ensuring the stability and reliability of the expansion, and improving the quality and efficiency of the expansion.

[0037] Figure 3 The following is a flow chart of the expansion control method of the tube expander provided by the embodiment of the present invention applied to the visual processing end. As shown in the figure, the method includes the following steps S210-S230.

[0038] S210, collecting an image of a pipe opening of the expanded workpiece, and performing image recognition on the image of the pipe opening to determine whether an abnormal pipe opening appears in the pipe opening of the expanded workpiece.

[0039] In this embodiment, the visual processing end acquires the image of the tube mouth of the workpiece after the tube expander is expanded by an acquisition device, wherein the acquisition device may be a camera. The visual processing end performs image recognition on the tube mouth image. Specifically, the visual processing end may preprocess the acquired tube mouth image, including steps such as denoising, contrast enhancement, and grayscale, so as to improve the image quality and provide more favorable conditions for subsequent image recognition, and extract key features such as edge contour and tube mouth diameter from the preprocessed tube mouth image through an image processing algorithm, so as to judge whether an abnormal tube mouth appears in the tube mouth of the expanded workpiece according to the extracted key features. For example, if a cracked tube mouth is shown in the tube mouth image, it can be judged that an abnormal tube mouth appears. The specific method for image recognition of the tube mouth image is not limited, and it is sufficient to be able to effectively judge the image. By acquiring the tube mouth image of the expanded workpiece, it is judged whether an abnormal tube mouth appears in the tube mouth of the expanded workpiece, so as to judge whether the expansion of the workpiece by the tube expansion device is abnormal, so as to adjust the expansion parameters in time or perform supplementary expansion in time.

[0040] In one embodiment, if Figure 4 As shown, the step S210 includes steps S211-S213.

[0041] S211, performing image recognition on the nozzle image, obtaining the nozzle diameter of each nozzle and comparing it with the target nozzle diameter;

[0042] S212, if there is a pipe opening with a diameter smaller than the target pipe opening, determining the pipe opening as an abnormally expanded pipe opening;

[0043] S213: If there is a pipe opening with a diameter larger than the target pipe opening and a gap, the pipe opening is determined to be an abnormally broken pipe opening.

[0044] In this embodiment, the target nozzle diameter is the standard nozzle size transmitted by the device controller to the visual processing end, wherein the standard nozzle size can be determined according to specific process requirements. The nozzle image is subjected to image recognition, specifically, the acquired nozzle 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 convolutional neural network CNN), which can automatically identify and extract key features from the image, including the edge, contour and other features of the nozzle, and can accurately measure the diameter of each nozzle. Among them, the specific method for image recognition is not limited, and it is sufficient to obtain the accurate diameter and the image of each nozzle. The nozzle diameter of each nozzle is compared with the target nozzle diameter. If the comparison result shows that there are nozzles smaller than the target nozzle diameter, then these nozzles are determined to be abnormal nozzles with expanded openings. If the nozzle diameter is larger than the target nozzle diameter, and it is confirmed by image recognition that there are gaps or cracks in the nozzle, then these nozzles are determined to be abnormal nozzles with broken openings. By performing image recognition on the nozzle image, obtaining the nozzle diameter of each nozzle and comparing it with the target nozzle diameter to determine abnormal nozzles, production efficiency can be improved, the cost and error of manual inspection can be reduced, and strong data support can be provided for subsequent process improvement and quality control.

[0045] S220, if any, perform expansion analysis on the abnormal pipe opening and generate corresponding expansion adjustment information.

[0046] In this embodiment, if the visual processing end finds the abnormal pipe mouth, the abnormal pipe mouth is expanded and analyzed, and specifically, the problem of the identified abnormal pipe mouth is carefully located. This includes determining the type of abnormal pipe mouth (such as insufficient expansion, rupture, etc.), as well as the specific location and degree of the abnormality (such as diameter deviation, notch size, etc.). Corresponding expansion adjustment information is generated for the specific problem of the abnormal pipe mouth. Specifically, for the ruptured pipe mouth, the expansion parameters that need to be adjusted are determined according to the diameter after the rupture, and the expansion adjustment information is generated according to the expansion parameters. By performing expansion analysis on the abnormal pipe mouth and generating corresponding expansion adjustment information, quality problems in the production process can be effectively solved, and product quality and production efficiency can be improved. This process requires the comprehensive use of professional knowledge, data analysis capabilities and practical experience to ensure the accuracy and effectiveness of the adjustment measures.

[0047] In one embodiment, if Figure 5 As shown, the step S220 includes steps S221-S222.

[0048] S221, if the abnormal pipe opening is a ruptured abnormal pipe opening, comparing the pipe opening diameter of the ruptured abnormal pipe opening with the target pipe opening diameter to obtain a rupture diameter difference;

[0049] S222: Generate the expansion adjustment information with new expansion parameters according to a preset diameter-depth ratio between the pipe orifice diameter and the expansion depth and the rupture diameter difference.

[0050] In this embodiment, if the abnormal pipe mouth is a ruptured abnormal pipe mouth, that is, a pipe mouth that is ruptured due to a large flaring depth, the pipe mouth diameter of the ruptured abnormal pipe mouth is compared with the target pipe mouth diameter to obtain the difference between the actual diameter of the ruptured abnormal pipe mouth and the target diameter. This difference reflects the degree of deviation of the ruptured abnormal pipe mouth in diameter. According to the preset diameter-depth ratio between the pipe mouth diameter and the flaring depth, the flaring adjustment information with new flaring parameters is generated. Among them, the preset diameter-depth ratio can be determined according to the specific flaring workpiece and the production target, the flaring depth is proportional to the pipe mouth diameter, and for every increase of 1mm in the flaring depth, the pipe mouth size will increase by a corresponding value according to the preset diameter-depth ratio. Therefore, according to the preset diameter-depth ratio and the rupture diameter difference, the flaring adjustment information with new flaring parameters can be generated. Specifically, according to the rupture diameter difference and the flaring ratio, the value of the flaring depth that needs to be reduced can be determined, so that the flaring adjustment information is generated according to the flaring depth that needs to be reduced. By calculating the rupture diameter difference and using the preset diameter-depth ratio to generate flaring adjustment information with new flaring parameters, it combines production experience and data analysis to ensure that the quality of the adjusted pipe mouth meets the standards while improving production efficiency and product quality.

[0051] In one embodiment, if Figure 6 As shown, the step S220 also includes steps S223-S226.

[0052] S223, if the abnormal pipe opening is an abnormal expansion pipe opening, obtaining the expansion diameter difference between the pipe opening diameter of the abnormal expansion pipe opening and the target pipe opening diameter;

[0053] S224, determining the supplementary expansion depth of the abnormally expanded pipe opening according to the expansion diameter difference and the preset diameter-depth ratio;

[0054] S225, determining the supplementary expansion position of the abnormally expanded pipe opening according to the preset position of the initial pipe opening and the preset distance between the pipe openings;

[0055] S226: Generate a signal to be supplemented according to the supplemented position and the supplemented depth, and send the signal to the device controller.

[0056] In this embodiment, the abnormal pipe opening is an abnormal expansion pipe opening, that is, an insufficiently expanded pipe opening, and the expansion diameter difference between the pipe opening diameter of the pipe opening and the target pipe opening diameter is calculated, wherein it should be noted that the abnormal pipe opening is caused by insufficient expansion, so the pipe opening diameter of the abnormal expansion pipe opening should be smaller than the target pipe opening diameter. The expansion depth of the abnormal expansion pipe opening when the expansion is performed is determined according to the expansion diameter difference and the preset diameter-depth ratio. For example, assuming that the preset diameter-depth ratio is 1:0.5, that is, for every increase of 1 unit of diameter, 0.5 units of depth need to be increased. If the expansion diameter difference is 2 units, then we can calculate that the expansion depth should be increased by 1 unit on the original expansion depth. The supplementary expansion position of the abnormally expanded pipe mouth is determined according to the preset initial pipe mouth position and the preset distance between the pipe mouths, wherein the distance between the pipe mouths is usually fixed. Assuming that the distance between the pipe mouths is 10 cm, and measuring the distance between the supplementary expansion device and the first pipe mouth at the initial position (assuming it is 11 cm) on site, assuming that the sixth pipe mouth needs to be supplemented, the distance the supplementary expansion device needs to travel is: 11+10*(6-1)(supplementary expansion position). Among them, the preset initial pipe mouth position is the distance between the supplementary expansion device and the first pipe mouth at the initial position. Finally, a signal to be supplemented is generated according to the determined supplementary expansion position and supplementary expansion depth, and the signal is sent to the equipment controller. The equipment controller will receive this signal and control the relevant supplementary expansion device to perform supplementary expansion operations. By generating a signal to be supplemented according to the supplementary expansion position and the supplementary expansion depth, the abnormally expanded pipe mouth is accurately supplemented to ensure that its diameter meets the production requirements.

[0057] In one embodiment, if Figure 7 As shown, step S226 also includes steps S2261-S2262.

[0058] S2261, after the expansion of the abnormally expanded pipe opening is completed, determining whether the expanded pipe opening is still an abnormally expanded pipe opening;

[0059] S2262: If yes, an abnormal alarm signal is generated.

[0060] In this embodiment, after the device controller controls the supplementary expansion device to supplement the expansion of the abnormal expansion nozzle, the visual processing end collects the nozzle image again to determine whether the nozzle after supplementary expansion is still an abnormal expansion nozzle, wherein the specific judgment steps are not repeated. If it is found after inspection that the nozzle after supplementary expansion is still an abnormal expansion nozzle, that is, its diameter still does not meet the target nozzle diameter requirement, then it means that there is an abnormality in the supplementary expansion device, such as the expander on the supplementary expansion device is not installed, and the nozzle cannot be corrected because the expander is not installed. Therefore, it is necessary to generate an abnormal alarm signal, which can be a simple indicator light flashing, a buzzer alarm, or a more complex electronic signal, which is used to trigger the shutdown of the production line, mark the abnormal nozzle or notify the operator. By generating an abnormal alarm signal when the nozzle after supplementary expansion is still an abnormal expansion nozzle, the relevant personnel are notified in time so that they can take further measures to deal with the abnormal expansion nozzle to prevent it from flowing into the next process or the final product, thereby ensuring product quality and production efficiency.

[0061] S230, sending the expansion adjustment information to the device controller.

[0062] In this embodiment, the flaring adjustment information is information for adjusting flaring parameters generated when the pipe mouth ruptures, for example, the information includes but is not limited to information for adjusting flaring depth. The flaring adjustment information is sent to the device controller, for example, information transmission can be performed through wired communication (such as Ethernet, RS-485, etc.) and wireless communication (such as Wi-Fi, Bluetooth, etc.), wherein the specific communication mode selected depends on the layout of the production line, the type of equipment, and the communication requirements. By sending the flaring adjustment information to the device controller, the device controller produces flared workpieces that meet the production requirements according to the flaring adjustment information, thereby improving product quality and production efficiency.
