Abstract

This invention provides a method for optimizing the material drop position of a feeding system. By comparing the actual drop position with the predicted drop position, the method determines whether the deviation exceeds a preset threshold. Based on the determination, the influencing parameters are adjusted accordingly. This method effectively optimizes the material drop position of the feeding system through model simulation and actual operation. By comparing the simulation prediction results with the actual operation results, and by comparing the deviation with the preset threshold, the corresponding influencing factors are adjusted to make the actual drop position of the material closer to the predicted drop position, thereby ensuring the efficiency and quality of subsequent automated laser cutting.

Description

Technical Field

[0001] This invention relates to the technical field of feeding device control technology, and specifically to a method for optimizing the material dropping position of a feeding system. Background Technology

[0002] The feeding process of the feeding system usually involves placing the material at the inlet end of the feeding component, which then feeds the material from the inlet end to the outlet end. The lifting device at the outlet end then lifts the material to the height of the chuck. The material is then clamped by the extension and retraction of the chuck and then transported to the machine tool behind for corresponding laser cutting and other operations.

[0003] During the feeding process, since subsequent laser cutting is often automated, a significant deviation between the actual landing point and the predicted landing point of the material at the top of the machine tool will adversely affect the efficiency and quality of the subsequent automated laser cutting.

[0004] Therefore, there is an urgent need to provide an optimization method for the material dropping position of the feeding system in order to solve the defects and shortcomings of the existing technology. Summary of the Invention

[0005] To address the shortcomings and deficiencies in existing technologies, this invention provides a method for optimizing the material drop position of a feeding system.

[0006] The specific solution provided by this invention is as follows:

[0009] S2: Input the initial position of the lifting device into the established feeding system model, and predict the landing position of the material;

[0010] S3: Determine the threshold parameters and optimization parameters based on the established feeding system model;

[0011] S4: The material is put in from the inlet end of the feeding device, fed to the outlet end by the feeding device, then lifted by the lifting device, and then sent to the top of the machine tool after being clamped by the chuck, and finally lowered to the top of the machine tool.

[0016] S7.2: When the material exceeds the preset radial deviation threshold only in the radial direction, the influencing parameters are adjusted accordingly based on the preset radial priority and preset radial adjustment amount;

[0017] S7.3: When the material exceeds the preset radial deviation threshold in both the axial and radial directions, first adjust the influencing parameters according to the preset axial priority and preset axial adjustment amount, repeat steps S4 to S7, and when the judgment condition is met, adjust the influencing parameters according to the preset radial priority and preset radial adjustment amount.

[0018] S8: Repeat steps S4 to S7 until the deviation between the actual landing point and the predicted landing point does not exceed the corresponding preset threshold.

[0019] S9: Record the optimization data and correct the parameters to be corrected in step S2.

[0020] As a further preferred embodiment of the present invention, the initial position of the lifting device in step S2 and the threshold parameter in step S3 are determined by a combination of empirical data and optimization data.

[0021] As a further preferred embodiment of the present invention, in step S3,

[0022] The threshold parameters include at least a preset threshold for axial deviation and a preset threshold for radial deviation;

[0023] The optimization parameters include at least a preset axial priority, a preset radial priority, a preset axial adjustment amount, and a preset radial adjustment amount.

[0025] As a further preferred embodiment of the present invention, in step S7.1, the preset axial priority satisfies the following: the adjustment priority of the rotation angle of the lifting shaft is higher than the adjustment priority of the position of the lifting device, and the adjustment priority of the position of the lifting device is higher than the adjustment priority of the telescopic displacement of the chuck.

[0026] As a further preferred embodiment of the present invention, in step S7.2, the preset radial priority satisfies the following: the adjustment priority of the position of the lifting device is higher than the adjustment priority of the telescopic displacement of the chuck, and the adjustment priority of the telescopic displacement of the chuck is higher than the adjustment priority of the rotation angle of the lifting shaft.

[0032] 1) This invention provides a method for optimizing the material drop position of a feeding system. By comparing the actual drop position of the material with the predicted drop position, it is determined whether the deviation between the two exceeds the corresponding preset threshold. Then, the influencing parameters are adjusted accordingly based on the judgment result. Thus, the material drop position of the feeding system is effectively optimized through model simulation and actual operation. By comparing the simulation prediction result with the actual operation result, and by comparing the deviation with the preset threshold, the corresponding influencing factors are adjusted so that the actual drop position of the material is closer to the predicted drop position, thereby ensuring the efficiency and quality of subsequent automated laser cutting work.

[0033] 2) This invention provides an optimization method for the material dropping position of a feeding system.

[0040] [First Embodiment]

[0041] like Figure 1-2 The figure shows a method for optimizing the material dropping position of a feeding system provided by the present invention, which includes the following steps:

[0042] S1: Input the feeding system parameters and establish a feeding system model. The established model is used to simulate the feeding process and thus predict the landing position of the material. In this embodiment, the input feeding system parameters should at least include feeding device parameters, lifting device parameters, and chuck parameters.

[0043] S2: Input the initial position of the lifting device into the established feeding system model and predict the landing position of the material; In this embodiment, the initial position of the lifting device is determined by a combination of empirical data and optimized data. By combining optimized data and empirical data as the basis for determining the initial position of the lifting device, the landing position can be continuously corrected and optimized, thereby further improving the accuracy and stability of the landing position.

[0044] S3: Determine the threshold parameters and optimization parameters based on the established feeding system model; the threshold parameters are determined by combining empirical data and optimization data. By combining optimization data and empirical data as the basis for determining the threshold parameters, continuous correction and optimization of the material dropping position can be achieved, further improving the accuracy and stability of the material dropping position; in this embodiment,

[0045] The determined threshold parameters include at least a preset threshold for axial deviation and a preset threshold for radial deviation; thus, when comparing the actual landing point of the material with the predicted landing point, the determination of whether the difference meets the preset thresholds for axial and radial deviation provides a basis for judgment.

[0046] The determined optimization parameters include at least the preset axial priority, preset radial priority, preset axial adjustment amount, and preset radial adjustment amount. The preset axial priority and preset radial priority determine the adjustment priority of the influencing factors in the axial and radial directions, respectively. The preset axial adjustment amount and preset radial adjustment amount determine the adjustment range of the influencing factors in the axial and radial directions, respectively. The adjustment priority and adjustment range will affect the accuracy and efficiency of the optimization adjustment.

[0047] S4: The material is fed into the inlet of the feeding device 1, then conveyed to the outlet position by the feeding device 1, then lifted by the lifting device 2, and then clamped by the chuck (not shown) slidably set on the sliding 3 before being sent above the machine tool, and finally lowered to the top of the machine tool; Figure 2 As shown, the length extension direction of material A is taken as the axial direction in this embodiment, and the width extension direction of material A is taken as the radial direction in this embodiment. Since the change in the height direction of material A during the feeding process is negligible relative to the deviation of the landing point in its length and width directions, the radial direction in this embodiment does not include the height extension direction in the usual sense.

[0048] S5: Record the actual landing point of the material;

[0049] S6: Compare the actual landing point of the material with the predicted landing point to determine whether the deviation between the two exceeds the corresponding preset threshold.

[0050] S7: Adjust the influencing parameters according to the judgment results: By comparing the actual landing position of the material with the predicted landing position, it is determined whether the deviation between the two exceeds the corresponding preset threshold. Then, the influencing parameters are adjusted accordingly based on the judgment results. Thus, the landing position of the feeding system is effectively optimized through model simulation and actual operation. By comparing the simulation prediction results with the actual operation results, and by comparing the deviation with the preset threshold, the corresponding influencing factors are adjusted so that the actual landing position of the material is closer to the predicted landing position, thereby ensuring the efficiency and quality of subsequent automated laser cutting work.

[0051] In this embodiment, the determined influencing parameters include at least the position of the lifting device, the rotation angle of the lifting shaft, and the telescopic displacement of the chuck. The position of the lifting device affects both the axial and radial positions of the actual landing point of the material. The rotation angle of the lifting shaft reflects the displacement change of the material's axis during the lifting process and ultimately affects the axial position of the actual landing point of the material. In order to achieve the clamping operation with the material lifted to a high position, the telescopic displacement of the chuck also affects the axial and radial positions of the actual landing point of the material.

[0052] The specific adjustment steps are as follows:

[0053] S7.1: When the material exceeds the preset threshold for axial deviation only in the axial direction, the influencing parameters are adjusted accordingly based on the preset axial priority and preset axial adjustment amount. In this embodiment, the preset axial priority satisfies the following: the adjustment priority of the rotation angle of the lifting shaft is higher than the adjustment priority of the position of the lifting device, and the adjustment priority of the position of the lifting device is higher than the adjustment priority of the telescopic displacement of the chuck. This is because when the lifting device lifts the material, the material at the top of the lifting shaft may move axially relative to the lifting shaft. This axial movement is intended to ensure that the material can find the optimal axial position after movement to achieve stable support at the top of the lifting shaft, and also indicates that the lifting device is capable of lifting. Since no unexpected damage occurred while the material was being lifted, this axial movement was unavoidable and caused the greatest axial deviation in the material's axial direction, thus requiring priority adjustment. The lifting device's position includes both axial and radial settings, so it affects the material's deviation in both directions. However, to achieve stable engagement with the top chuck, this effect is relatively small compared to the rotation angle of the lifting shaft, therefore its adjustment priority is second. The chuck's telescopic displacement is for engaging with the material, and it only achieves axial and radial telescopic movement within a small range (the chuck is simultaneously positioned in both axial and radial dimensions), therefore its adjustment priority is the lowest.

[0054] S7.2: When the material exceeds the preset radial deviation threshold only in the radial direction, the influencing parameters are adjusted accordingly based on the preset radial priority and preset radial adjustment amount. In this embodiment, the preset radial priority satisfies the following: the adjustment priority of the lifting device's position is higher than the adjustment priority of the chuck's telescopic displacement, and the adjustment priority of the chuck's telescopic displacement is higher than the adjustment priority of the lifting shaft's rotation angle. This is because the lifting device's position includes both its axial and radial positions, thus affecting the material's deviation in both the axial and radial directions. Therefore, its adjustment priority needs to be set to the highest during radial adjustment. The chuck's telescopic position only achieves axial and radial telescopic movement within a small range, so its adjustment priority can be set relatively low. The rotation angle of the lifting shaft only causes the material to change axially (the material is clamped on both radial sides), and does not change radially, thus not affecting the radial position of the material's actual landing point. Therefore, its adjustment priority is set to the lowest.

[0055] S7.3: When the material exceeds the preset threshold for radial deviation in both the axial and radial directions, the influencing parameters are first adjusted according to the preset axial priority and preset axial adjustment amount. Steps S4 to S7 are repeated. When the judgment condition is met, that is, the axial deviation between the actual landing point and the predicted landing point does not exceed the preset threshold for axial deviation, the influencing parameters are then adjusted according to the preset radial priority and preset radial adjustment amount. This is because the axial deviation caused by the feeding device, lifting device, and chuck device to the actual landing point of the material has a greater impact than the radial deviation. On the other hand, in the subsequent automated laser cutting and other corresponding operations performed on the rear machine tool, the axial deviation of the actual landing point of the material has a greater impact than the radial deviation. Therefore, it is necessary to minimize or eliminate the axial deviation as much as possible before considering the radial deviation. Therefore, correspondingly, as a preferred embodiment, the preset axial adjustment amount of the position of the lifting device and the extension displacement of the chuck are both greater than the corresponding preset radial adjustment amount.

[0056] S8: Repeat steps S4 to S7 until the deviation between the actual landing point and the predicted landing point does not exceed the corresponding preset threshold.

[0057] S9: Record optimization data and correct the parameters to be corrected. In this step, the recorded optimization data includes at least the influencing parameters of the optimization adjustment and the corresponding optimization adjustment amount, so that the process and magnitude of each adjustment are recorded to provide a basis for subsequent optimization processes. The parameters to be corrected include at least the initial position and threshold parameters of the lifting device. By combining the optimization data and empirical data as the basis for determining the initial position and threshold parameters of the lifting device, the dropping position can be continuously corrected and optimized, thereby further improving the accuracy and stability of the dropping position.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
