[0001] The invention relates to the technical field of automobile parts processing, and in particular to an automobile parts processing production line and a production process thereof. Background Art

[0002] In the existing automotive parts processing technology, it is usually necessary to continuously and finely process the workpiece in multiple processes to achieve the required accuracy and quality. To achieve this, the existing technology often uses multiple machining centers to form a collaborative production line, and each machining center independently processes different parts of the workpiece. However, due to the different working environments, workpiece clamping positions and processing temperatures of each machining center, when the workpiece travels back and forth between different machining centers during a long, intermittent transfer and clamping process, cumulative errors are likely to occur, especially when the production cycle is long or the line is changed frequently. In this way, when the workpiece is finally tested for accuracy, the accumulated errors will have a significant impact on the dimensional accuracy and comprehensive performance of the finished product.

[0003] For this reason, an automobile parts processing production line and a production process thereof are proposed to solve the above-mentioned problems. Summary of the invention

[0004] The present invention aims to provide an automobile parts processing production line and its production process, so as to solve or improve the above-mentioned technical problem that in the collaborative operation of multiple machining centers in the automobile parts processing process, due to differences in environment and operation, the workpiece generates cumulative errors during the processing, which ultimately affects the accuracy and performance of the finished product.

[0005] In view of this, a first aspect of the present invention is to provide an automobile parts processing production line.

[0006] A second aspect of the present invention is to provide a production process.

[0007] The first aspect of the present invention provides an automobile parts processing production line, comprising: n machining centers, arranged in sequence along a machining sequence to gradually process a blank into the automobile parts; on each of the machining centers, a first temperature parameter for processing the blank is set according to the position in the machining sequence, and a temperature path for processing the blank is constructed according to all the first temperature parameters; a turnover mechanism, at least one of which is provided and located between adjacent machining centers; the turnover mechanism is used to transport the blank to the machining center so that the current second temperature parameter of the blank is adapted to the first temperature parameter.

[0008] In any of the above technical solutions, the turnover mechanism includes a sensor unit corresponding to the processing position of the blank, and the sensor unit is used to obtain temperature values ​​of multiple positions of the blank; the turnover mechanism heats or cools the blank according to all the second temperature parameters.

[0009] In any of the above technical solutions, the first temperature parameter is a range value, and the temperature path is a broken line path formed by connecting multiple temperature nodes in sequence, and there is a preset threshold between the temperature value included in the second temperature parameter and the temperature value of the temperature node.

[0010] In any of the above technical solutions, the preset threshold is set according to the machining error required by the blank in the current machining center, and / or the temperature value of the temperature node is within the range of the first temperature parameter.

[0011] In any of the above technical solutions, the automobile parts processing production line also includes a temperature control system, which is used to control the turnover mechanism to heat or cool the blank according to the first temperature parameter and the second temperature parameter; the temperature control system adjusts each of the first temperature parameters through the third temperature parameter of the current processing environment to correct the temperature path, and the temperature control system updates and stores the temperature path at each moment.

[0012] In any of the above technical solutions, the temperature control system includes: a temperature acquisition module, connected to the sensor unit; the temperature acquisition module is used to package the temperature values ​​of multiple parts of the blank as the second temperature parameter at the current moment; a workpiece temperature control module, connected to the turnover mechanism; the temperature control module is used to generate control data based on the second temperature parameter and the first temperature parameter of the blank when it arrives at the machining center.

[0013] In any of the above technical solutions, the temperature control system also includes: a path update module, which is used to determine whether the control data controls the turnover mechanism to adjust the temperature difference of the blank is greater than the preset threshold; if it is greater, adjust the temperature value of the temperature node and update the temperature path.

[0014] In any of the above technical solutions, the blank includes a frame structure, and the automobile accessories include an automobile ladder frame formed by processing the frame structure; the turnover mechanism includes a turnover box capable of accommodating the frame structure.

[0015] In any of the above technical solutions, when the turnover box transports the frame structure between adjacent machining centers, the following situations occur: In situation one, the frame structure is heated or cooled so that the temperature of each circumferential portion of the frame structure is consistent; In situation two, each circumferential portion of the frame structure is heated or cooled so that the first temperature parameter of the frame structure is adapted to the second temperature parameter of the machining center at the next position in the machining sequence.

[0016] The second aspect of the present invention provides a production process, comprising the following steps: preheating the blank to a set temperature value, and passing the heated blank through the machining center in sequence along the machining sequence; continuously judging whether the second temperature parameter of the blank is compatible with the first temperature parameter of the machining center to be reached, and if not, heating or cooling the blank.

[0017] Compared with the prior art, the present invention has the following beneficial effects: By setting the first temperature parameter that matches the processing sequence position for the blank in each machining center, the blank can be in the ideal temperature range of precise control before entering the respective processing link. This not only helps to reduce deformation and errors in subsequent cutting, forming or welding processes, but also ensures the orderly connection and stable quality between the various processes as a whole.

[0018] When the blank is transferred between adjacent machining centers, the turnover mechanism can dynamically adjust the actual temperature of the blank to the aforementioned first temperature parameter range through its heating and cooling functions, thereby avoiding the influence of sudden temperature changes on material properties and dimensional accuracy during the continuous transfer of the workpiece, and effectively ensuring that the blank is always maintained at an appropriate temperature condition during a long, multi-step production process.

[0019] The overall temperature path constructed after considering the first temperature parameters of all machining centers makes the temperature of the blank transition smoothly and evenly distributed along the machining sequence by reasonably arranging the values ​​of each temperature node. This not only reduces the heating and cooling time and energy consumption of the blank to a minimum, but also enables the entire production line to achieve continuous control of temperature conditions in production tasks of different types and batches, reducing cumulative errors and improving the final accuracy of the finished product.

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] See also Figure 1-Figure 3 , the following describes an automobile parts processing production line and its production process according to some embodiments of the present invention.

[0025] The embodiment of the first aspect of the present invention provides an automobile parts processing production line. In some embodiments of the present invention, such as Figure 1-Figure 2 As shown, the automotive parts processing production line includes: n machining centers are arranged in sequence along a machining sequence to gradually process the blank into auto parts; the first temperature parameter of the blank is set on each machining center according to the position in the machining sequence, and the temperature path of the blank is constructed according to all the first temperature parameters. The blank is a rough blank with the general shape and structure of auto parts after die casting; the first temperature parameter is different in each machining sequence, and the required temperature of the machining center in each machining sequence is considered respectively. The temperature path constructed by the first temperature parameter considers the machining temperature value and the difference between each other, ensuring the stability of the blank shape during long-term and multi-process machining, so as to minimize the accumulated error caused by multiple intermittent machining.

[0026] A turnover mechanism is provided, and at least one is located between adjacent machining centers to transfer the blanks between the machining centers and realize continuous machining operations; when the turnover mechanism is used to transport the blanks to the machining center, the blanks are adapted to the first temperature parameters at the current second temperature parameters, not only to ensure that the blanks can meet the temperature requirements of the next processing operation after long-term and multiple intermittent processing, but also to establish temperature continuity between adjacent machining operations, so as to avoid morphological changes and inevitable machining errors of the blanks caused by temperature differences when they are processed in different processes.

[0027] The present invention provides an automobile parts processing production line, which aims to effectively reduce the cumulative error caused by intermittent transmission and clamping during the collaborative operation of multiple processing centers by optimizing the temperature control path, thereby improving the dimensional accuracy and comprehensive performance of the finished product. In the specific implementation process, the automobile parts processing production line includes multiple (n) processing centers, which are arranged in sequence according to a specific processing sequence, and gradually process the blank into the final automobile parts. First, the blank is a rough blank with a rough shape structure of automobile parts after die casting, which ensures the basic form of subsequent processing. In each processing center of the production line, a corresponding first temperature parameter is set according to its specific position in the entire processing sequence. The first temperature parameters of each processing center are different, and the setting of these temperature parameters fully considers the processing temperature required by the center to adapt to the specific temperature requirements of different processing processes. By comprehensively considering the first temperature parameters set by all processing centers, a complete temperature path for processing blanks is constructed. This temperature path not only covers the specific temperature values ​​required by each processing center, but also considers in detail the differences in temperature parameters between adjacent processing centers to ensure the smoothness and rationality of temperature transition.

[0028] During long-term and multi-process processing, the blank may be deformed due to temperature changes in different processing centers. By constructing a scientific and reasonable temperature path, the temperature change amplitude of the blank in each processing link can be effectively controlled, the stability of its shape can be maintained, and deformation and stress concentration caused by temperature fluctuations can be prevented, thereby reducing the cumulative errors generated during the processing process. Since the transfer and clamping of workpieces between multiple processing centers are intermittent, each clamping and transfer may introduce tiny errors. The optimized design of the temperature path unifies and coordinates the temperature control of each processing center, reduces the processing errors caused by temperature differences, and effectively suppresses the accumulation of errors as a whole, ensuring that the workpiece can still maintain high precision after going through multiple processing links.

[0029] A reasonable temperature path not only helps to stabilize the shape and control errors, but also optimizes the efficiency of thermal energy utilization during the processing. By accurately controlling the temperature parameters of each processing center, the heating and cooling time of the workpiece in each processing link can be shortened, the processing efficiency of the entire production line can be improved, the production cycle can be reduced, and the production capacity can be increased. The construction of the temperature path requires close coordination between the various processing centers. The temperature parameters of each center are uniformly managed and adjusted through an integrated control system to ensure that each processing center processes at the most suitable temperature in the same time period. This collaborative optimization not only improves the overall coordination of the production line, but also extends the service life of the equipment and reduces maintenance costs. By building a stable temperature path, the temperature environment of each batch of workpieces during the processing process is ensured to be consistent, thereby ensuring the consistency of product quality. No matter how long the production line runs or how complex the processing task is, the temperature path can be controlled to maintain the stability and repeatability of the workpiece processing process and ensure the high quality of the final product.

[0030] The turnover mechanism is arranged between adjacent processing centers, and the number is determined to be at least one according to the specific needs of the production line. The main components of the turnover mechanism may include one or more of the following: a conveyor belt, a temperature control device, an automatic clamping device, and a control system. The conveyor belt is used to move the blanks between the processing centers to ensure that they can be processed smoothly and continuously. The temperature control device is integrated in the turnover mechanism and is responsible for adjusting the temperature of the blanks during the transportation process to achieve the adaptation of the second temperature parameter to the first temperature parameter. The automatic clamping device is used to quickly and accurately complete the clamping and release of the blanks during the transportation process, reducing the errors caused by human operation. The control system uses software algorithms to monitor and adjust the various parameters of the turnover mechanism in real time to ensure the stability and efficiency of the entire transportation process.

[0031] When the turnover mechanism transports the blank to the machining center, it needs to adapt the temperature of the blank. Specifically, after being processed by the previous machining center, the blank is at the current second temperature parameter. The turnover mechanism gradually adjusts the temperature of the blank to the first temperature parameter required by the next machining center. This process not only involves the rise and fall of temperature, but also needs to consider the rate of temperature change and the smoothness of transition to prevent the workpiece from being unstable or causing stress concentration due to sudden temperature changes. After the blank leaves the previous machining center, the turnover mechanism begins to make preliminary temperature adjustments to ensure that the temperature of the blank fluctuates within a reasonable range and avoids the impact of changes in ambient temperature. Through the precise control of the temperature control device, the temperature of the blank is gradually adjusted to the first temperature parameter required by the next machining center. In this process, the temperature change of the blank is monitored in real time and fed back to the control system to ensure the accuracy of the temperature adjustment process. In order to achieve a smooth transition of temperature, the control system formulates a reasonable temperature adjustment curve according to the temperature requirements of the machining center to avoid changes in the workpiece shape and machining errors caused by too fast temperature changes.

[0032] By adapting the temperature of the blank to the turnover mechanism, the temperature continuity between adjacent processing steps is established. This design effectively avoids the morphological changes and processing errors of the workpiece caused by excessive temperature differences. Between the processing centers, the turnover mechanism adjusts the temperature gradient to ensure that the temperature changes of the blank between different processes remain within a controllable range. This not only reduces the thermal stress of the workpiece during the transmission process, but also avoids deformation caused by uneven temperature. The temperature control device of the turnover mechanism maintains the thermal balance of the blank during the transportation process, ensuring that it is in an ideal temperature state when entering the next processing center. This helps to improve processing accuracy and reduce dimensional errors caused by temperature fluctuations. The construction of temperature continuity enables each process in the entire processing process to be carried out in a consistent temperature environment, thereby ensuring the consistency and stability of the processing technology and improving the quality of the final product.

[0033] In a production line with multiple machining centers working together, it is inevitable that small errors will occur during the transfer and clamping of workpieces between different machining centers. As the number of machining times increases, these errors may accumulate, ultimately affecting the accuracy and performance of the product. The temperature adaptation function of the turnover mechanism effectively controls the accumulation of errors. By accurately controlling the temperature of the blank, the morphological changes of the workpiece caused by temperature fluctuations are reduced, thus reducing the generation of machining errors from the source. By real-time monitoring of temperature and workpiece status, timely adjustment of temperature parameters and transfer speed, it is ensured that all parameters in the machining process are always in the best state to prevent the accumulation of errors.

[0034] The turnover mechanism not only functions independently, but also works in coordination with other parts of the entire processing line to achieve overall optimization. The temperature control system of the turnover mechanism and the processing center is managed uniformly through an integrated control system to ensure that the temperature parameters between the processing centers are coordinated and consistent, optimizing the overall production process. Through the sensor network, the turnover mechanism shares key data such as temperature, humidity, and processing speed with each processing center, and uses big data analysis and machine learning algorithms to optimize the construction and adjustment strategies of the temperature path and improve the intelligence level of the production line.

[0035] In any of the above embodiments, the turnover mechanism includes a sensor unit corresponding to the processing position of the blank, and the sensor unit is used to obtain temperature values ​​of multiple positions of the blank.

[0036] The turnover mechanism heats or cools the blank according to all the second temperature parameters. If the second temperature parameter of the current blank meets the first temperature parameter requirement of the next machining center along the machining sequence, the temperature of the blank can be maintained according to the difference between the ambient temperature and the second temperature parameter of the blank.

[0037] In this embodiment, a sensor unit needs to be introduced in the design of the turnover mechanism, which is responsible for real-time monitoring of the temperature values ​​of multiple parts of the blank. The sensor unit is set at different parts of the blank, mainly used to accurately obtain the temperature data of each key part of the blank. These temperature data will be fed back to the control system of the turnover mechanism in real time and participate in the dynamic adjustment of the temperature control process. Specifically, the role of the sensor unit includes: the sensor unit monitors the temperature of the blank in real time and transmits it to the central control system of the turnover mechanism. These temperature data reflect the actual temperature condition of the blank at the current stage, which helps to find the temperature deviation in time, facilitates to take measures to adjust the temperature, and avoids the situation where the temperature does not meet the requirements. The temperature changes of blanks at different parts may be inconsistent during the processing, so the sensor unit can help identify the temperature distribution of different parts. This information is crucial for further optimizing the temperature control strategy to ensure that the blank as a whole is within a suitable temperature range. The sensor unit can continuously feedback data to the control system, and these data are used to adjust the subsequent heating or cooling operations. For example, if the temperature of a part of the blank is too high or too low, the control system will automatically adjust the temperature control operation of the turnover mechanism according to the sensor data, so that the blank can meet the temperature conditions required for its processing when it reaches the next processing center.

[0038] Based on the temperature values ​​of multiple parts of the blank obtained from the sensor unit, the temperature control system of the turnover mechanism heats or cools the blank according to all the second temperature parameters. The temperature control function of the turnover mechanism mainly adjusts the temperature of the blank by heating or cooling it to ensure that the blank can meet the first temperature parameter requirements of the process when entering the next processing center. The temperature adjustment process includes: if the current temperature of the blank is lower than the first temperature parameter required by the next processing center, the temperature control device of the turnover mechanism will start the heating process; if the temperature is too high, the cooling process will be started. In this process, the turnover mechanism will determine the rate and intensity of heating or cooling according to the difference between the actual temperature value of the blank and the ambient temperature to achieve precise control. Since the shape of the blank is closely related to the temperature, too fast or too slow temperature changes may cause processing errors. By accurately controlling the heating or cooling rate, the turnover mechanism can gradually and steadily adjust the temperature of the blank to the target temperature, avoiding the adverse effects of sudden temperature difference changes on the workpiece shape or processing accuracy. When adjusting the temperature, the temperature adjustment path is optimized based on the working environment of the turnover mechanism and the difference between the current second temperature parameter of the blank and the target temperature. This intelligent adjustment function accurately controls the working mode of the heating and cooling equipment by analyzing and processing the real-time data feedback from the sensor unit, ensuring that the temperature adjustment is gradual and meets the process requirements.

[0039] In any of the above embodiments, the first temperature parameter is a range value, the range value is set according to the processing temperature requirement of the machining center and the material properties of the workpiece itself, and the temperature path is a broken line path formed by connecting multiple temperature nodes in sequence, and there is a preset threshold between the temperature value included in the second temperature parameter and the temperature value of the temperature node, which is used to limit the difference between the temperature nodes of the first temperature parameter on adjacent machining centers.

[0040] In this embodiment, the first temperature parameter is set according to the specific processing requirements of the machining center and the material properties of the blank itself. This temperature parameter has a certain range of values, which is intended to set a suitable temperature range for each machining process to ensure that the blank can maintain its ideal physical and chemical properties during the machining process, while avoiding deformation, cracks or other machining defects caused by excessively high or low temperatures. Specifically, the setting process of the first temperature parameter includes: the temperature required for each machining center is different when performing different processes. For example, in some processes, higher temperatures may be required to promote certain physical processes (such as annealing, quenching, etc.), while in other processes, lower temperatures may be required to ensure delicate processing. In this case, the first temperature parameter will be set to a temperature range according to different machining processes to ensure that the machining center can perform machining tasks within a suitable temperature range. The sensitivity of the material properties of the blank to temperature is crucial, and the performance of different materials at different temperatures varies greatly. For example, the processing temperature requirements of aluminum alloys and steel are very different. In order to ensure the processing quality of the blanks on each processing center, the first temperature parameter will be appropriately adjusted according to the thermophysical properties of the material (such as thermal expansion coefficient, thermal conductivity, etc.) and the corresponding processing requirements to ensure that the temperature range can match the optimal processing temperature of the material. Since the temperature requirements of different processes may fluctuate to a certain extent, the first temperature parameter is set to a range value so that the temperature fluctuation during the processing is within an acceptable range and will not have an adverse effect on the processing of the blanks. The setting of this temperature range allows the production line to adjust the temperature more flexibly when facing different workpieces, thereby adapting to different processing requirements.

[0041] The temperature path is a broken line path formed by connecting multiple temperature nodes in sequence. The purpose is to describe the temperature change trajectory of the blank between each processing step to ensure the continuity and stability of the temperature change. The functions and effects of the temperature path include: the temperature path is composed of multiple temperature nodes, each temperature node represents a specific temperature value, and the blank needs to adjust its temperature in sequence according to these temperature nodes during the processing. Each temperature node has a certain temperature difference with its previous and next nodes. The size and order of these differences will directly affect the morphological stability and processing accuracy of the blank. The broken line structure of the temperature path allows the temperature change to gradually transition between different processing steps, avoiding sudden temperature jumps or sharp changes. Each inflection point of the broken line path corresponds to a specific temperature node, and by controlling the difference between the temperature nodes, the blank can smoothly transition to the temperature state required by the next process during the processing, thereby reducing the processing error. When constructing the temperature path, the control system needs to reasonably arrange the temperature nodes according to the requirements of different processing steps. By optimizing the construction of the temperature path, the temperature change can be made smoother, and it is ensured that the temperature conversion from one processing center to the next processing center will not affect the morphological stability of the blank due to excessive temperature fluctuations.

[0042] The second temperature parameter is used to describe the temperature state reached by the blank during the transportation and temperature control process of the turnover mechanism. The function of the second temperature parameter is to adjust the temperature of the blank according to the relationship between the actual temperature value of the blank and its preset first temperature parameter, so as to ensure that the temperature meets the requirements during the processing of each processing center. The temperature value of the second temperature parameter corresponds to each temperature node in the temperature path. By setting the second temperature parameter, the control system can ensure that the temperature of the blank is kept within a reasonable range during the transportation process, thereby avoiding the adverse consequences caused by the temperature change too fast or too slow during the transportation of the blank. There is a preset threshold between the temperature value contained in the second temperature parameter and the temperature value of the temperature node. The threshold is used to limit the difference between the temperature nodes of adjacent processing centers, so as to avoid the morphological changes or inevitable processing errors caused by the excessive temperature difference during the transportation of the blank from one processing center to the next processing center. The purpose of the preset threshold is to limit the temperature change amplitude of the blank during the actual processing process to avoid the processing error caused by the excessive temperature difference. By setting a suitable threshold, the system can smoothly transition between each processing step, avoiding the morphological changes and errors caused by temperature fluctuations, thereby ensuring the processing accuracy. In some cases, if the temperature requirements of the processing process are more special, the control system can adjust the threshold according to the actual situation to adapt to the processing requirements of different materials or different workpieces. For example, for some parts with high precision requirements, the threshold can be set more strictly to ensure that the temperature difference during the processing is minimized and reduce errors.

[0043] Specifically, the first temperature parameter is used as a range value to ensure that the temperature of each machining center is processed within an appropriate range; while the second temperature parameter ensures that the blank can smoothly transition to the temperature requirement of the next machining center by adjusting the temperature in real time. The temperature path forms a broken line path by connecting multiple temperature nodes, ensuring the continuity and stability of temperature changes. Through the synergistic effect of these three features, the entire production line can reduce the error caused by temperature changes while ensuring accuracy. The sensor unit monitors the temperature of the blank in real time and feeds the data back to the temperature control system, which adjusts the second temperature parameter based on the feedback data to maintain the temperature of the blank. Between each machining center, the temperature control system adjusts the temperature of the blank according to each temperature node in the temperature path to ensure a smooth transition between different processes and avoid morphological changes due to excessive temperature differences. The entire system adjusts the temperature path, temperature nodes and thresholds of the blank in real time through intelligent control to ensure that the temperature changes continuously between multiple machining centers, avoids large temperature jumps or fluctuations, and minimizes morphological changes and machining errors caused by temperature differences.

[0044] In any of the above embodiments, the preset threshold is set according to the machining error required by the blank in the current machining center, and / or the temperature value of the temperature node is within the range value of the first temperature parameter to ensure that the temperature value of the temperature node that has been corrected and updated multiple times must meet the machining process requirements of the machining center.

[0045] In this embodiment, the main function of the preset threshold in the present invention is to ensure that the change of the temperature node meets the processing requirements of each machining center during the correction and update of the temperature of the blank during the machining process, and can effectively limit the morphological changes and machining errors caused by excessive temperature fluctuations. The setting process of the preset threshold takes into account the following aspects: The setting of the preset threshold first considers the machining error range required by the blank in the current machining center. The machining process of each machining center has a certain error tolerance. Excessive temperature differences may cause the blank to undergo morphological changes (such as expansion, contraction, etc.), thereby causing a decrease in machining accuracy. To this end, the preset threshold is set according to the actual machining error requirements of each machining process. This error requirement is dynamically adjusted based on the accuracy requirements and process characteristics of the machining center. An important function of the preset threshold is to limit the difference in temperature nodes between adjacent machining centers according to the specific machining requirements of the machining center. For example, in some precision machining processes, the requirements for temperature changes are very strict, and any temperature fluctuations may affect the final machining quality. In other more relaxed processes, the tolerance for temperature fluctuations is relatively high. Therefore, by setting appropriate thresholds, the temperature node differences between adjacent machining centers can be kept within an acceptable range, ensuring that the morphological changes of the blank are minimized, thereby effectively reducing machining errors. The preset threshold also ensures that the temperature values ​​of the temperature nodes after multiple corrections and updates always meet the machining process requirements required by each machining center. Before the blank is transferred to the next machining center, the temperature control system will adjust and correct its temperature in real time to ensure that the temperature nodes meet the preset temperature range and the difference between the temperature nodes also meets the tolerance requirements for machining errors. This can effectively avoid deformation or unqualified parts caused by excessive or insufficient temperature.

[0046] The temperature node is a key element in building the temperature path, representing the temperature state of the blank between each machining center. The role of the preset threshold is to limit the temperature difference between these temperature nodes to avoid excessive or rapid temperature changes, which may lead to machining errors. The following is the relationship between the temperature node and the preset threshold: Due to the different processing requirements of each machining center, the temperature change of the blank from one machining center to another needs to be properly adjusted. The preset threshold limits the maximum temperature difference of the temperature nodes between adjacent machining centers to ensure that the temperature change is not too large, avoiding part deformation or reduced machining accuracy caused by excessive temperature differences. In this way, the transition of the temperature path appears smoother, so that the temperature difference between each machining process is reasonably controlled. The preset threshold can be adjusted according to the requirements of different machining processes. For example, for precision machining processes, strict control of temperature fluctuations is required, so a smaller threshold is set to make the changes between temperature nodes smoother; while for some machining processes with a larger tolerance, the threshold can be appropriately relaxed to allow a slightly larger temperature difference. The flexible adjustment of the preset threshold enables temperature control to be precisely adjusted according to different machining requirements. Each machining center has a specific range of temperature requirements, and the temperature of the blank needs to be processed within this range. Before processing in each machining center, the system will adjust the second temperature parameter to ensure that the temperature value of the temperature node is within the preset range. If the temperature value of the temperature node exceeds the required range of the machining center, the preset threshold will trigger the temperature correction mechanism, thereby automatically adjusting the temperature path to ensure that the temperature adjustment meets the process requirements of each machining process.

[0047] The temperature path is the temperature change trajectory of the blank between the various processing centers. The setting of the preset threshold is closely related to the construction of the temperature path. Specifically, the preset threshold has a correlation effect on the smoothness and stability of the temperature path: the temperature path consists of multiple temperature nodes, and the temperature change between the nodes needs to transition smoothly. The preset threshold limits the temperature difference between adjacent nodes to avoid excessive fluctuations in the temperature path and ensure that the temperature changes are smooth and stable throughout the production process. This smooth temperature change helps to maintain the shape of the blank and avoid deformation or processing errors caused by excessive temperature fluctuations. During the processing, the temperature of the blank may fluctuate due to changes in the external environment or heat loss during the transmission process. At this time, the preset threshold plays a role in optimizing the adjustment of the temperature path. By monitoring the temperature of the blank in real time and dynamically correcting the temperature nodes according to the preset threshold, the system can ensure that the temperature path is always kept within the optimal range, thereby ensuring that the temperature requirements of each processing center are met. The setting of the preset threshold ensures that the temperature difference between each node of the temperature path is not too large, which meets the temperature control standards of the processing technology. The smooth transition of the temperature path and the reasonable temperature difference between nodes help to ensure the temperature consistency of the blank between multiple processing steps, avoid processing errors caused by excessive temperature changes, and ultimately improve the accuracy of the finished product.

[0048] The setting of the preset threshold is related to the function of the temperature control system. In practical applications, the temperature control system adjusts the temperature of the blank by collecting the temperature data of the blank in real time and comparing it with the preset threshold. The specific synergy includes: when the temperature control system detects that the temperature of the blank deviates from the preset temperature range, it triggers the temperature correction mechanism to adjust the temperature path and temperature nodes. The role of the preset threshold is to limit the amplitude of the temperature correction and avoid temperature fluctuations caused by excessive correction. The temperature control system achieves precise temperature control of the blank by adjusting the heating or cooling equipment according to the preset temperature path and temperature nodes. The preset threshold ensures that the difference between the temperature nodes does not exceed the tolerance of the processing technology, thereby ensuring the accuracy and stability of the temperature control. By reasonably setting and applying the preset threshold, the temperature control system can avoid morphological changes caused by excessive temperature differences while ensuring temperature stability, thereby significantly improving the processing accuracy of the blank.

[0049] In any of the above embodiments, the automobile parts processing production line further includes a temperature control system, and the temperature control system is used to control the turnover mechanism to heat or cool the blank according to the first temperature parameter and the second temperature parameter.

[0050] The temperature control system adjusts each first temperature parameter by a third temperature parameter of the current processing environment to correct the temperature path, and the temperature control system updates and stores the temperature path at each moment. The temperature control system includes a path storage module for updating and storing the temperature path in real time.

[0051] In this embodiment, the main function of the temperature control system is to heat or cool the blank according to the first temperature parameter and the second temperature parameter, and to ensure that the blank is kept in a suitable temperature range during the processing by real-time monitoring and adjusting the temperature required by each processing center. The temperature control system mainly has the following functions: The temperature control system heats or cools the blank based on the first temperature parameter (i.e., the temperature range required by each processing center) and the second temperature parameter (i.e., the current temperature of the blank). Through the precise adjustment of the temperature control system, it is ensured that the blank is always in a suitable processing temperature state, avoiding deformation or unqualified problems caused by excessively high or low temperatures. The temperature control system controls the heating or cooling device so that the temperature of the blank gradually reaches or is maintained within the required temperature range. The temperature control system adjusts the first temperature parameter of each processing center in real time according to the third temperature parameter (i.e., the actual temperature of the current processing environment) to correct and optimize the temperature path in the entire production process. By real-time monitoring the impact of the ambient temperature on the temperature of the blank, the temperature control system can dynamically adjust the temperature nodes in the temperature path to ensure a smooth temperature change and avoid the adverse effects of temperature fluctuations caused by changes in the external environment on the processing accuracy. The temperature control system can not only obtain the temperature data of the blank and the processing environment in real time, but also has the function of updating and storing the temperature path in real time. The temperature control system saves the temperature path data of all processing processes through the storage module, which is convenient for subsequent temperature control adjustment and quality traceability, ensuring that there are no omissions or errors in the temperature control process.

[0052] The first temperature parameter and the second temperature parameter work together in the temperature control system to ensure the temperature stability of the blank throughout the entire processing line: the first temperature parameter is the temperature requirement of each processing center, which is set according to the process requirements of the processing process. The first temperature parameter is different in the processing sequence of each processing center, and the specific value depends on the temperature control requirements of different processing processes. By setting the first temperature parameter, the system can guide the required temperature range of each processing center and provide the blank with an ambient temperature suitable for processing. The second temperature parameter refers to the current actual temperature of the blank. The temperature control system determines the current temperature state of the blank according to the second temperature parameter, and then decides whether to heat or cool the blank to reach the temperature range set by the first temperature parameter. When the temperature control system detects that there is a gap between the temperature of the blank (the second temperature parameter) and the temperature requirement of the processing center (the first temperature parameter), the system will start the heating or cooling device to gradually adjust the temperature of the blank to the required temperature range.

[0053] The third temperature parameter is the temperature of the current processing environment, which directly affects the temperature change of the blank. Fluctuations in ambient temperature may cause uneven changes in the temperature of the blank, which in turn affects the accuracy of processing. Therefore, the temperature control system needs to dynamically correct the temperature path according to the current ambient temperature to ensure that the temperature changes in the entire production process meet the predetermined requirements: when the third temperature parameter changes, the temperature control system will adjust the first temperature parameter according to this change to correct the temperature path. In this way, the accuracy of the temperature parameters required by each machining center can be maintained to avoid unnecessary temperature errors caused by changes in ambient temperature. The temperature control system updates and adjusts the temperature path in real time to ensure that at any time, the temperature of the blank can adapt to the current processing environment and processing requirements. In this way, the temperature control system avoids processing errors caused by excessive temperature fluctuations while ensuring a smooth temperature transition.

[0054] The path storage module is one of the core components of the temperature control system, responsible for updating and storing the data of the temperature path in real time. This module can not only save the data of all temperature changes during the processing, but also make dynamic adjustments according to the actual changes of the temperature path. The functions of the path storage module are reflected in the following aspects: the temperature control system monitors each temperature node in the processing process in real time, and records the temperature value and its changes of each node in the path storage module. When the temperature control system detects that the temperature path needs to be adjusted, the storage module will automatically update the temperature path to ensure that the temperature changes of each processing center are accurately recorded and adjusted. The path storage module is not only used to store the current temperature path data in real time, but also to archive and manage historical data. In this way, the temperature control system can be optimized and adjusted according to historical data to ensure more accurate temperature control in future processing. By storing and updating the temperature path, the path storage module can provide important temperature reference data for subsequent processing procedures. In this way, each processing procedure can be adjusted according to the temperature data of the previous process to ensure the consistency and stability of temperature control of the entire production line.

[0055] In any of the above embodiments, the temperature control system includes: The temperature acquisition module is connected to the sensor unit; the temperature acquisition module is used to package the temperature values ​​of multiple parts of the blank as the second temperature parameter at the current moment.

[0056] The workpiece temperature control module is connected to the turnover mechanism; the temperature control module is used to generate control data according to the second temperature parameter and the first temperature parameter of the blank material when it arrives at the machining center.

[0057] In this embodiment, the temperature acquisition module is the first module in the temperature control system, which is mainly responsible for real-time monitoring and acquisition of the temperature of each part of the blank through the sensor unit. These temperature data will be used to construct the second temperature parameter, that is, the real-time temperature state of the current blank during the processing. The functions of the temperature acquisition module include: the temperature acquisition module obtains the temperature values ​​of different parts of the blank through the connection with the sensor unit. These temperature values ​​provide the current state information of the blank and provide basic data for the subsequent temperature control process. The sensor unit is usually installed at multiple key positions of the blank to ensure that the temperature change of the blank can be fully and accurately monitored. In the temperature acquisition module, the temperature values ​​of multiple parts are packaged and processed to form a complete second temperature parameter. These data not only represent the current temperature state of the blank, but also reflect the distribution of the temperature of the blank at different parts. Through these data, the system can accurately identify the parts with uneven temperature and perform heating or cooling as needed. The temperature acquisition module acquires the temperature data of the blank in real time at all times, and updates these data in real time to the second temperature parameter at the current moment. Such real-time monitoring and data updating ensure that the temperature control system can dynamically adjust subsequent temperature control operations according to the changing temperature conditions of the blank during the production process.

[0058] The workpiece temperature control module is the second key module of the temperature control system. It is responsible for generating control data based on the second temperature parameter (i.e., the real-time temperature data of the blank obtained by the temperature acquisition module) and the first temperature parameter required by the machining center, and transmitting the data to the turnover mechanism to adjust the temperature of the blank. The main functions of this module include: the workpiece temperature control module generates specific temperature control data based on the second temperature parameter provided by the temperature acquisition module, i.e., the current temperature state of the blank, and the first temperature parameter (i.e., the temperature required by each machining center). The first temperature parameter is the temperature range set under the process requirements of the machining center, while the second temperature parameter reflects the current temperature state of the blank. The function of the workpiece temperature control module is to match these two parameters to ensure that the blank can be processed under the process requirements of the next machining center. The workpiece temperature control module determines whether the blank is in the appropriate temperature range by comparing the current second temperature parameter with the first temperature parameter of the target machining center. If there is a difference between the temperature of the blank and the requirements of the first temperature parameter, the workpiece temperature control module will generate corresponding control data based on the difference, instructing the turnover mechanism to heat or cool the blank to reach the temperature required by the machining center. Through this adjustment method, the system ensures that each machining center can perform precise processing under the set temperature conditions. The workpiece temperature control module is connected to the turnover mechanism through the generated control data to ensure that the temperature adjustment can be carried out smoothly. Specifically, the temperature control module transmits the control signal for adjusting the temperature of the blank to the turnover mechanism, instructing it to heat or cool the blank. The turnover mechanism starts the relevant heating or cooling device according to these control signals, thereby adjusting the temperature of the blank to adapt to the upcoming processing steps. The workpiece temperature control module not only ensures that the temperature of the blank reaches the first temperature parameter requirement required by the machining center, but also ensures the stability of the temperature change. By generating control data, the workpiece temperature control module can effectively avoid machining errors caused by excessive or small temperature fluctuations, ensuring that the machining process of each machining center can proceed smoothly and the quality of the final product is guaranteed.

[0059] Specifically, first, the temperature acquisition module is responsible for monitoring the temperature of the blank and summarizing the temperature data of each part into the second temperature parameter to provide basic data for the workpiece temperature control module. The workpiece temperature control module compares these data with the first temperature parameter (temperature requirement of the machining center) to generate the control data required to adjust the temperature of the blank. The control data is then transmitted to the turnover mechanism to instruct it to perform heating or cooling operations, and finally achieve precise temperature adjustment. The temperature acquisition module provides real-time and comprehensive temperature data to help the workpiece temperature control module identify the temperature state of the blank. The workpiece temperature control module formulates the most suitable temperature adjustment scheme by comprehensively considering the difference between the second temperature parameter and the first temperature parameter. The control data of the temperature control module ensures that the blank can be accurately adjusted in the turnover mechanism, avoiding extreme situations of too high or too low temperature, thereby ensuring that the temperature of the blank always meets the requirements during the processing process. The entire temperature control system forms a closed-loop control process. The temperature acquisition module provides real-time data, and the workpiece temperature control module generates control instructions based on the data and adjusts the temperature through the turnover mechanism. In this way, the temperature control system can adjust and optimize the temperature control strategy in real time during the production process to ensure that the temperature of each process is always in the most suitable state.

[0060] In any of the above embodiments, the temperature control system further includes: The path updating module is used to determine whether the temperature difference of the blank adjusted by the control data control turnover mechanism is greater than a preset threshold; if it is greater, the temperature value of the temperature node is adjusted, the temperature path is updated, and the updated temperature path is transmitted to the path storage module.

[0061] In this embodiment, the primary function of the path update module is to determine whether the difference in the temperature of the blank controlled by the turnover mechanism to adjust the temperature of the blank generated by the workpiece temperature control module is greater than a preset temperature threshold. This judgment is based on the fact that the control data generated by the workpiece temperature control module contains a temperature adjustment instruction calculated based on the second temperature parameter (current temperature of the blank) and the first temperature parameter (temperature requirements of each processing center). These control data clearly define the temperature change requirements of the blank. The path update module calculates the temperature difference of the blank between different processing centers in real time, especially when the turnover mechanism needs to be heated or cooled during the processing process, the temperature difference of the blank is an important reference value. The difference reflects the gap between the current temperature of the blank and the temperature of the target processing center. The preset threshold is a maximum allowable temperature difference set according to the material properties of the blank and the precision requirements of the processing technology. When the temperature difference exceeds this threshold, the path update module will determine that the temperature is not suitable and needs to be adjusted.

[0062] Once the path update module detects that the temperature difference is greater than the preset threshold, the module triggers a series of adjustment actions. The specific process is as follows: the path update module adjusts the temperature nodes in the temperature path according to the temperature difference. Each temperature node represents the temperature target value of the blank on a specific machining center. If the temperature value of a temperature node is too high or too low, the path update module will make appropriate adjustments based on the current temperature difference to make it more in line with the requirements of the machining process. The adjusted temperature value of the temperature node will affect the entire temperature path. The temperature path is a broken line path formed by connecting multiple temperature nodes in sequence. It is not only the temperature change trajectory during the machining process, but also reflects the temperature change trend of the blank during the entire machining process. The path update module replans and updates the temperature path according to the adjusted temperature node value to ensure that the temperature requirements of each machining center can be met throughout the production process. By updating the temperature path, the path update module ensures the temperature continuity and consistency during the machining process. No matter which link of the production line, the temperature of the blank will be accurately controlled to reduce the machining error caused by uneven temperature, thereby ensuring the accuracy of the final product.

[0063] After the temperature path is updated, the path update module passes the latest temperature path data to the path storage module. The functions of the path storage module are as follows: the path storage module will receive and save the latest version of the temperature path in real time, ensuring that the historical data of the temperature path can be retrieved at any time to avoid losing key information of temperature control. The path storage module not only saves data, but also provides a basis for subsequent temperature path adjustment and optimization. During the production process, if the temperature path needs to be readjusted or corrected at a certain stage, the historical data stored in the path storage module can provide the necessary information support for such adjustment. The path storage module can also provide data backtracking function. When any problems occur during the production process, the operator can trace back the temperature path data to the temperature state of the blank at a certain moment, help locate potential problems caused by temperature changes, and take effective corrective measures.

[0064] Furthermore, the temperature control system also includes a data sending module, and the turnover mechanism includes a temperature control device, which heats or cools the blank by heating the air and generating airflows of different temperatures; wherein the data sending module is connected to the temperature control device of the turnover mechanism by wire or wireless means to transmit control data to the temperature control device.

[0065] As can be seen from the above, the data transmission module is responsible for transmitting control data between various components in the temperature control system. These control data are calculated based on the current temperature of the blank, the target temperature and related processing requirements. The control data usually includes instruction information such as temperature setting value, adjustment method, target time, etc. These data will guide the temperature control equipment to heat or cool the blank, so as to ensure that its temperature meets the requirements during the processing of each processing center. The data transmission module is connected to the temperature control equipment in the turnover mechanism by wired or wireless means, which means that the system can work in a traditional wired network environment, and can also transmit data through a wireless network or other wireless protocols in a wireless communication environment. Through this flexible connection method, the temperature control system can be widely used in different production environments and different layouts. The real-time and accuracy of the data transmission module ensure the effective operation of the temperature control system. It continuously obtains and transmits the latest control data, so that the temperature control equipment can adjust the temperature of the blank in time to avoid the impact of temperature deviation on the quality of the workpiece.

[0066] In any of the above embodiments, the blank includes a frame structure, and the automobile accessory includes an automobile ladder frame formed by processing the frame structure.

[0067] The turnover mechanism includes a turnover box that can accommodate the frame structure. The sensor unit and the temperature control device are both installed on the turnover box and aligned with the position where the blank is installed inside the turnover box, specifically the part where the blank is processed. Therefore, the sensor unit includes multiple temperature sensors with different detection directions.

[0068] In this embodiment, the blank is a raw material that has undergone preliminary processing and has a general shape and structure of an automobile part. In an embodiment of the present invention, the blank includes a frame structure, which provides a basic shape for the blank and supports the processing of the entire part. Specifically, the frame structure not only determines the initial shape of the blank, but also serves as a key part for supporting and transmitting force during the processing, and plays a role of bearing and positioning in subsequent processing steps. The blank is processed multiple times by the machining center and finally forms an automobile accessory, specifically an automobile ladder frame. The automobile ladder frame is obtained by processing and forming the frame structure, completing the final processing of the blank so that it meets the structural requirements of automobile accessories.

[0069] As a key device for transferring blanks from one processing center to the next, the turnover mechanism can ensure that the blanks are smoothly transferred and continued to be processed between multiple processing centers. The design of the turnover mechanism not only needs to meet the basic function of transporting blanks, but also needs to provide support for temperature control and monitoring. The function of the turnover mechanism is not limited to material transportation, it is also closely related to the temperature monitoring and regulation of the temperature control system. Through the coordinated work of the sensor unit and the temperature control equipment, the turnover mechanism ensures that the blanks maintain an ideal temperature during the transfer process between the processing centers to avoid errors caused by temperature differences. The main function of the sensor unit is to monitor the temperature of multiple parts of the blank in real time and transmit the temperature data to the temperature control system, thereby providing necessary feedback information for the temperature control equipment. Specifically, the sensor unit includes multiple temperature sensors with different directions, which are distributed in multiple positions of the turnover box to ensure comprehensive temperature detection of each processing part of the blank.

[0070] Specifically, the arrangement and orientation of each temperature sensor are set according to the processing part, with the aim of ensuring the comprehensiveness and accuracy of the temperature data. Through temperature sensors in multiple directions, the sensor unit can capture the temperature change information of each local area in a timely manner when different temperature changes occur in different parts of the blank, and accurately reflect the temperature state of the entire blank. The orientation design of the sensor is adapted to the processing part of the blank to ensure that the temperature of each processing part can be accurately monitored. For example, the key processing surface of the blank may be equipped with more temperature sensors for parts that need special attention, while the number of sensors can be reduced for other less sensitive parts. The sensor unit can transmit the data to the temperature control system in a timely manner by monitoring the temperature of the blank in real time. These temperature data will serve as input signals to help the temperature control equipment adjust the temperature of the heating or cooling airflow to ensure that the temperature of the blank is always in the best state during the processing process.

[0071] In any of the above embodiments, when the turnover box is transporting the frame structure between adjacent processing centers, the following conditions exist: In the first case, a part or the entire structure of the frame structure along the circumference is heated or cooled so that the temperature of each part of the frame structure along the circumference is consistent.

[0072] In the second scenario, each position of the frame structure along the circumference is heated or cooled so that the first temperature parameter of the frame structure is adapted to the second temperature parameter of the machining center at the next position in the machining sequence.

[0073] In this embodiment, when the turnover box transports the frame structure between adjacent processing centers, it particularly realizes temperature control of the frame structure to ensure its temperature uniformity and adaptability during the processing. Specifically, the turnover box performs the following two operations through the temperature control device to adapt to different processing requirements and ensure the temperature adaptability of the frame structure. These two situations have their own functions and interrelated effects.

[0074] Regarding scenario 1, in this case, the temperature control device focuses on adjusting the temperature of the frame structure along the circumference to ensure that the temperature of each part is consistent. This is usually important in the processing process because the uniformity of temperature directly affects the processing accuracy and the physical properties of the material. By heating or cooling specific parts of the frame structure, the temperature control device adjusts the temperature distribution so that the temperature of each part along the circumference is consistent, thereby reducing physical deformation or stress concentration caused by uneven temperature. Temperature control of specific parts can prevent the overall processing quality from being affected by local excessively high or low temperatures, especially in complex processing tasks such as welding or heat treatment. The sensor unit monitors the real-time temperature of each part of the frame structure along the circumference and feeds the data back to the temperature control device. Based on this data, the temperature control device can accurately adjust the temperature of the required parts to ensure uniform temperature distribution. Maintaining the temperature uniformity of the frame structure helps maintain the consistency of the entire temperature path, which is the key to achieving high-quality processing. The path update module adjusts the temperature path based on real-time data to ensure that the temperature regulation meets the requirements of the processing center.

[0075] For scenario 2, this scenario is more focused on ensuring that the temperature of each part of the frame structure is not only uniform, but also adapts to the temperature requirements of the upcoming machining center. This is a more sophisticated temperature control process that involves pre-adjusting the temperature to adapt to the specific needs of the next process. By adjusting the temperature of each part, it is ensured that the temperature of the entire frame structure is not only uniform, but also meets the specific temperature requirements of the next machining center. This adaptive temperature adjustment helps optimize subsequent processing efficiency and quality. In multi-process processing, each machining center may have different requirements for the temperature of the material. By pre-adjusting the temperature of the frame structure, problems caused by temperature mismatch when entering a new machining center can be prevented, such as unstable material properties or reduced machining accuracy.

[0076] The embodiment of the second aspect of the present invention provides a production process. In some embodiments of the present invention, such as Figure 3 As shown, the production process includes the following steps: S101, preheating the blank to a set temperature value, and passing the heated blank through the machining center in sequence along the machining sequence.

[0077] S102, continuously judging whether the second temperature parameter of the blank is adapted to the first temperature parameter of the processing center to be reached, and if it is not adapted, heating or cooling the blank.

[0078] In a production process provided by the present invention, the main function of step S101 is to heat the blank to a preset temperature value. Preheating is a key preliminary stage in the entire production process, and the purpose is to make the blank reach a temperature state suitable for processing to ensure that the physical and chemical properties of the blank meet the processing requirements when it is processed in the subsequent machining center. The temperature value is determined based on the material properties of the blank and the specific processing technical requirements of the machining center. Correct temperature setting can reduce the internal stress of the material, avoid cracks or deformation during processing, thereby improving processing accuracy and material utilization. The preheated blank will be further processed by different machining centers in turn. Each machining center has specific processing tasks, and the blank preheated to the appropriate temperature can more effectively accept these processes, such as cutting, forming, welding, etc. For example, in the manufacture of automotive parts, the steel plate blank may need to be preheated to about 250°C in order to be formed in the subsequent stamping machining center. Preheating ensures the ductility and shape stability of the steel plate during stamping, reducing material loss and workpiece scrap rate.

[0079] Step S102 involves real-time monitoring of the temperature of the blank (the second temperature parameter) and determining whether it matches the temperature (the first temperature parameter) required by the upcoming machining center. This continuous monitoring and determination is to ensure that the blank is always kept at the best temperature conditions throughout the production process to meet the process requirements of different machining centers. If the current temperature of the blank does not meet the temperature requirements of the next machining center, heating or cooling adjustments are required. This adjustment ensures that the blank has a temperature state suitable for processing when it arrives at each machining center, thereby improving machining efficiency and reducing errors in the machining process. For example, when manufacturing aviation parts, the temperature of an aluminum alloy blank may be too high after processing in the initial machining center, and the temperature needs to be adjusted by cooling before being transferred to the precision machining center. The real-time monitoring system ensures that the aluminum alloy reaches the ideal processing temperature of about 200°C before precision machining to avoid material softening caused by high temperature affecting machining accuracy.
