Abstract
Description
A multi-station synchronous correction control system for air conditioning copper pipes Technical Field
[0001] This application relates to the field of air conditioning copper pipe technology, and in particular to a multi-station synchronous correction control system for air conditioning copper pipes. Background Technology
[0002] In air conditioning systems, the copper pipes connecting the indoor and outdoor units are crucial for refrigerant circulation. Their geometric shape and dimensional accuracy, especially straightness, roundness, and pipe diameter consistency, directly affect the system's sealing performance, refrigerant flow efficiency, vibration and noise levels, and long-term operational reliability. During the air conditioning production line, after undergoing pre-processing such as winding, transportation, cutting, and bending, the copper pipes inevitably experience varying degrees of bending, twisting, or localized deformation. Therefore, precise straightening of the copper pipes before assembly is an essential and critical step.
[0003] Traditional copper pipe straightening methods primarily rely on manual inspection combined with simple mechanical clamps for single-point or segmental manual straightening. This method is not only labor-intensive and inefficient, but the straightening quality also depends entirely on the operator's experience and skill level, resulting in poor consistency and difficulty in guaranteeing accuracy. Manual straightening can easily lead to over- or under-straightening of the copper pipe, and may even cause damage to the pipe wall, create new stress concentration points, or cause the copper pipe to harden due to improper force, thus creating potential hazards for subsequent leaks.
[0004] In existing technologies, single-station equipment typically uses preset fixed parameters for correction, lacking real-time perception and dynamic feedback of the initial morphology of the copper tube. It cannot adaptively adjust the correction strategies and forces required for different positions and degrees of deformation, resulting in low intelligence. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] As shown in Figure 1, a preferred embodiment of the present application discloses a multi-station synchronous straightening control system for air conditioning copper pipes, comprising: a copper pipe straightening unit for straightening copper pipes to be processed; a detection unit for collecting structural parameters of the copper pipes to be processed; and a central control unit, comprising: a first processing module for establishing a copper pipe analysis model; the first processing module is further configured to set a primary straightening strategy based on the structural parameters of the copper pipes to be processed and the copper pipe analysis model; the first processing module is further configured to set the operating parameters of the copper pipe straightening unit based on the primary straightening strategy; and a second processing module for establishing a linkage monitoring model; the second processing module is further configured to determine whether to generate a compensation straightening command based on the linkage monitoring model.
[0027] Specifically, the copper tube straightening unit includes: multiple workstation structures; wherein, each workstation structure includes multiple straightening points; each straightening point is equipped with a straightening submodule and a monitoring submodule; the straightening submodule is used to execute the first-level straightening strategy; and the monitoring submodule is used to acquire straightening feedback data of the copper tube to be processed.
[0028] Specifically, the correction submodule is preferably a pressure actuator, which is used to apply radial correction force to the copper tube. The correction submodule is set on the position adjustment device, which can ensure that the force of the correction submodule is accurately applied above the copper tube.
[0029] Specifically, a single workstation structure includes multiple correction points, each of which is equipped with a correction submodule and a monitoring submodule. Different workstation structures can simultaneously correct different copper tubes in the same batch.
[0030] Specifically, the monitoring submodule preferably includes a force sensor and a displacement sensor (preferably a high-precision grating ruler in this application). The force sensor can monitor the actual corrective force applied to the copper tube to be processed in real time, and the displacement sensor can monitor the actual radial deformation of the pressure point of the copper tube to be processed in real time.
[0031] Specifically, the working parameters (i.e. the radial correction force and application position to be applied) to be executed by each correction sub-module in each individual workstation structure are set according to the primary correction strategy.
[0032] Specifically, the correction feedback data refers to the actual correction force applied to the copper tube to be processed and the actual radial deformation of the pressure point of the processed copper tube, collected by the monitoring submodule.
[0033] It is understandable that in the above embodiments, a central control unit and a copper pipe analysis model are added. By analyzing the structural parameters of the copper pipe to be processed, the correction parameters are dynamically adjusted, reducing the debugging cost of copper pipes of unknown specifications and improving the system's correction efficiency for air conditioning copper pipes.
[0034] In a preferred embodiment of this application, the first processing module is further configured to: establish a copper tube record library based on historical correction record data, the copper tube record library including multiple copper tube fittings; establish a copper tube fitting sequence A, A=(a1,a2…ai…an), where ai is the i-th copper tube fitting; n is the number of copper tube fittings; sequentially set ai as the target copper tube fitting according to the copper tube fitting sequence A; generate an associated data packet of the target copper tube fitting based on the historical correction record data; set the correction sub-strategy of the target copper tube fitting according to the associated data packet; sequentially generate the correction sub-strategy of each copper tube fitting; and establish a copper tube analysis model based on the copper tube record library and all correction sub-strategies.
[0035] Specifically, the historical correction record data includes the structural parameters of all batches of copper tubes that underwent correction processing by the system, the correction data performed on each copper tube, and the collected correction feedback data.
[0036] Specifically, a copper pipe record library is established based on the structural parameters of each copper pipe. Each copper pipe fitting represents a type of copper pipe, and the structures of each copper pipe fitting are different.
[0037] Specifically, the associated data packet of the target copper fitting contains the correction data that has been performed on the copper pipe corresponding to the fitting and the correction feedback data collected when the copper pipe is being corrected.
[0038] Specifically, set the correction sub-strategy for the target copper pipe fitting, including: establishing a correction point sequence B based on the station structure; B = (b1, b2…bi…bm), where bi is the i-th correction point in the single station structure based on the position order; m is the number of correction points in the single station structure; sequentially set bi as the target correction point according to the correction point sequence B; set the correction parameters of the target correction point for the target copper pipe fitting according to the associated data packet; sequentially set the correction parameters of each correction point for the target copper pipe fitting; set the basic sub-strategy of the target copper pipe fitting according to all the correction parameters; set the deviation correction sub-strategy of each correction point for the target copper pipe fitting; set the correction sub-strategy of the target copper pipe fitting according to the basic sub-strategy and all the deviation correction sub-strategies.
[0039] Specifically, establish a correction point sequence B according to the order of the positions of each correction point in the station structure (i.e., the order of first contacting the copper pipe).
[0040] Specifically, by analyzing the associated data packet of the target copper pipe fitting, generate the optimal working parameters of the target correction point (i.e., the optimal radial correction force and the application position when the target correction point completes the expected correction of the target copper pipe fitting), and set the optimal working parameters as the correction parameters of the target correction point for the target copper pipe fitting.
[0041] Specifically, generate a basic sub-strategy according to the set correction parameters of each correction point for the target copper pipe fitting. The single station structure can complete the correction work of the copper pipe corresponding to the target copper pipe fitting by executing the basic sub-strategy (in the case where there is no execution error in the station structure).
[0042] Specifically, set the deviation correction sub-strategy of each correction point for the target copper pipe fitting, including: sequentially set bi as the target correction point according to the correction point sequence B; generate the deviation correction efficiency value of each correction point for the target correction point; preset a deviation correction efficiency value threshold F1; if F1 < fi (i = 1, 2…m), set the i-th correction point as the deviation correction point of the target correction point; where fi is the deviation correction efficiency value of the i-th correction point for the target correction point; obtain all the deviation correction points of the target correction point; set the deviation correction sub-strategy of the target correction point according to all the deviation correction points.
[0043] Specifically, the deviation correction efficiency value threshold can be set according to historical parameters.
[0044] Specifically, the deviation correction efficiency value can set a first deviation correction value according to the relative position between the current correction point and the target correction point. If the current correction point is in front of the target correction point, the first deviation correction value is zero. If the current correction point is behind the target correction point, the first deviation correction value is set according to the position distance between the current correction point and the target correction point. The smaller the position distance, the larger the corresponding first deviation correction value, and the mapping relationship between the two can be set according to historical parameters.
[0045] Specifically, a second deviation correction value is set according to the expected correction amount of the current correction point. The larger the expected correction amount, the larger the corresponding second deviation correction value. The mapping relationship between the two can be set according to historical parameters, and the value ranges of the first deviation correction value and the second deviation correction value are the same.
[0046] Specifically, the deviation correction efficiency value of the current correction point with respect to the target correction point is set according to the weighted processing result of the first deviation correction value and the second deviation correction value. The weight coefficients of the first deviation correction value and the second deviation correction value can be set according to the position parameters of each correction point (generally, the farther the position of the current correction point is, the larger the weight coefficient of the first deviation correction value, the smaller the weight coefficient of the second deviation correction value, and the sum of the two weight coefficients is 1).
[0047] Specifically, if the deviation correction efficiency value of the current correction point with respect to the target correction point is greater than the preset deviation correction efficiency value threshold, it means that the current correction point can compensate and correct the deviation of the correction amount that appears in the target correction point, so as to ensure the precise correction of the copper tube to be processed.
[0048] Specifically, all deviation correction points corresponding to the target correction point are included in the deviation correction sub-strategy of the target correction point. When a deviation of the correction amount appears in the target correction point, each deviation correction point evenly distributes the deviation of the correction amount and performs compensation correction.
[0049] It can be understood that in the above embodiments, by analyzing all the correction points of the single-station structure, the basic sub-strategies of each copper pipe fitting (i.e., different types of historical copper tubes) are set, so as to achieve the precise correction of different copper pipe fittings, and by setting the deviation correction sub-strategies of each correction point for different copper pipe fittings, the interference of the operation error of a single correction point in the station structure on the overall correction effect is avoided, and the correction accuracy of the air-conditioning copper tube by the system is improved.
[0050] In the preferred embodiment of the embodiment of the present application, the first processing module is further configured to: obtain the structural parameters of the copper tube to be processed; generate the similarity values between the copper tube to be processed and each copper pipe fitting in the copper pipe record library according to the structural parameters; obtain the maximum value c of all the similarity values max ; preset a similarity value threshold C1; if c max > C1, set the correction sub-strategy of the copper pipe fitting corresponding to the maximum value c max as the first-level correction strategy; if c max < C1, generate a first-level correction instruction according to the structural parameters of the copper tube to be processed; set the basic sub-strategy of the copper pipe fitting corresponding to the maximum value c max as the initial basic strategy; generate a first-level basic strategy according to the first-level correction instruction and the initial basic strategy; obtain all the deviation correction sub-strategies of the copper pipe fitting corresponding to the maximum value c max ; generate a first-level correction strategy according to the first-level basic strategy and all the deviation correction sub-strategies.
[0051] Specifically, the similarity threshold can be set according to historical parameters. If the similarity value between the copper pipe to be processed and the current copper pipe fitting is greater than the preset similarity threshold, it means that the copper pipe to be processed is the copper pipe corresponding to the current copper pipe fitting (that is, the system has processed the same copper pipe as the copper pipe to be processed before). The correction sub-strategy of the copper pipe fitting can be directly called to complete the correction of the copper pipe to be processed.
[0052] Specifically, multiple structural indicators are set based on historical correction record data. These structural indicators include, but are not limited to, copper tube hardness, copper tube outer diameter, copper tube wall thickness, copper tube length, ellipticity of copper tube cross-section, overall curvature, and bending type, among other copper tube structural parameters that affect the correction effect of the workstation structure.
[0053] Specifically, based on the collected structural parameters of the copper tube to be processed, the various structural index parameters of the copper tube to be processed are screened, and the feature vector of the copper tube to be processed is generated. The various structural index parameters of the current copper fitting are obtained, and the feature vector of the current copper fitting is generated. The distance between the feature vector of the copper tube to be processed and the feature vector of the current copper fitting is calculated by cosine similarity. The smaller the distance, the greater the corresponding similarity value. The mapping relationship between the two can be set according to historical parameters.
[0054] Specifically, when the maximum value c max When the value is less than the similarity threshold, it indicates that the copper pipe to be processed is an unknown specification copper pipe that the system has never processed before. In this case, the maximum value c is called according to the first-level correction instruction. max The corresponding correction sub-strategy is optimized. The working parameters of the basic sub-strategy in the correction sub-strategy are dynamically modified according to the structural parameters of the copper tube to be processed. The first-level correction strategy is set according to the optimization and correction results. The first-level correction strategy is continuously corrected online by continuously collecting correction feedback data to ensure the correction accuracy of the copper tube to be processed.
[0055] In a preferred embodiment of this application, the second processing module is further configured to: obtain correction feedback data of all correction points; sequentially select correction points to be evaluated from all correction points; generate correction deviation value d of the correction points to be evaluated; preset correction deviation value threshold D1; if d>D1, generate compensation correction instruction for the correction points to be evaluated; and sequentially determine whether to generate compensation correction instructions for each correction point.
[0056] Specifically, the correction deviation threshold can be set based on historical parameters. If the correction deviation value of the point to be evaluated is greater than the preset correction deviation threshold, it indicates that the current correction point has not completed the expected correction task for the corresponding position of the copper pipe to be processed. A compensation correction instruction needs to be generated to complete the expected correction task for that position using subsequent correction points.
[0057] Specifically, the compensation and correction instructions include: setting the correction sub-strategy of the correction point to be evaluated as the correction strategy to be executed based on the primary correction strategy; generating the correction difference of the correction point to be evaluated; and setting the compensation and correction parameters based on the correction strategy to be executed and the correction difference.
[0058] Specifically, each correction point in the correction strategy to be executed is set as the execution correction point.
[0059] Specifically, the location point of the correction deviation on the copper tube to be processed caused by the correction point to be evaluated and the difference in correction amount (i.e., the difference between the expected correction amount at this location generated according to the first-level correction strategy and the actual correction amount at this location generated according to the correction feedback data collected by the monitoring submodule) are obtained. The difference in correction amount is then distributed evenly to generate the compensation amount for each correction point and compensation correction is performed.
[0060] Specifically, the correction deviation value d of the point to be evaluated is generated, including: d=g U1 (k1-k2) ； g=U2 ( j i Where, g is the correction compensation coefficient; U1 is the preset first fixed coefficient; U2 is the preset second fixed coefficient; k1 is the expected correction amount of the correction point to be evaluated; k2 is the actual correction amount of the correction point to be evaluated generated based on correction feedback data; r1 is the number of associated correction points of the correction point to be evaluated in the linkage monitoring model; j i It generates the auxiliary evaluation value of the i-th associated correction point based on the correction feedback data.
[0061] Specifically, the first and second fixed coefficients can be set based on historical parameters. By setting the first fixed coefficient, the correction deviation value is kept within a preset range. And g The larger the value of (k1-k2), the larger the corresponding correction deviation value.
[0062] Specifically, by presetting a second fixed coefficient, the correction compensation coefficient is kept within a fixed range, and ( j i The larger the value of ), the larger the corresponding correction compensation coefficient value, and the mapping relationship between the two can be set according to historical parameters.
[0063] Specifically, the correction points in the same position in different workstation structures are interconnected correction points.
[0064] Specifically, k1 is the expected correction amount of the to-be-evaluated correction point for the current position of the to-be-processed copper tube generated according to the primary correction strategy, and k2 is the actual correction amount of the current position point generated according to the correction feedback data collected by the monitoring sub-module.
[0065] Specifically, generate the correction amount difference of each associated correction point at the same moment, and set the auxiliary evaluation value of the current correction associated point according to the ratio of the correction amount difference of the current associated correction point to the correction amount difference of the to-be-evaluated correction point (the correction amount difference of the associated correction point is the numerator). The smaller the ratio (indicating that the possibility of correction deviation of the to-be-evaluated correction point is greater), the greater the corresponding auxiliary evaluation value, and the mapping relationship between the two can be set according to historical parameters.
[0066] It can be understood that in the above embodiments, a multi-station layout and a linkage monitoring model are added to timely warn of local deviations during the correction process of the to-be-processed copper tube, achieve synchronous correction of different copper tubes in the same batch, prevent error accumulation, and improve the correction accuracy of the system for air-conditioning copper tubes.
[0067] In the preferred embodiment of the present application, the central control unit further includes: an update module for obtaining the correction record data of the to-be-processed copper tube; the update module is also used to obtain the maximum value c of the similarity values of the to-be-processed copper tube and each copper fitting in the copper tube record library max ; If c max > C1, generate a primary update instruction for the copper tube analysis model according to the correction record data; if c max < C1, generate a secondary update instruction for the copper tube analysis model according to the correction record data.
[0068] Specifically, the primary update instruction is to optimize and update the correction sub-strategy of the copper fitting corresponding to the to-be-processed copper tube according to the correction record data, so as to improve the correction accuracy of the system for air-conditioning copper tubes.
[0069] Specifically, the secondary update instruction means that the to-be-processed copper tube is a brand-new copper tube. A new copper fitting is constructed according to the structural parameters of the to-be-processed copper tube, and by analyzing the correction record data, the corresponding basic sub-strategy and the deviation correction sub-strategy of each correction point are set, so as to add a new copper fitting and the corresponding correction sub-strategy to the copper tube analysis model, improve the matching efficiency of the copper tube analysis model for copper tubes of unknown specifications, and improve the adaptability of the system to complex and changeable working conditions.
[0070] According to the first concept of the present application, a central control unit and a copper tube analysis model are added. By analyzing the structural parameters of the to-be-processed copper tube, the correction parameters are dynamically adjusted, the debugging cost of copper tubes of unknown specifications is reduced, and the correction efficiency of the system for air-conditioning copper tubes is improved.
[0071] According to the second concept of this application, a multi-station layout and linkage monitoring model are added to provide timely warnings of local deviations during the copper tube straightening process, enabling synchronous straightening of different copper tubes in the same batch, preventing error accumulation, and improving the system's straightening accuracy for air conditioning copper tubes.
[0072] The above description is only a preferred embodiment of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
