[0058] See also Figure 1 As shown, an embodiment of the present application provides a method for designing and implementing a process for a square-outer-circle inner-circle product. The method for designing and implementing a process for a square-outer-circle inner-circle product includes:

[0059] Based on the design drawing parameters and actual processing parameters of the outer square inner circle product, the finished product specification parameters corresponding to the outer square inner circle product are obtained; based on the finished product specification parameters, the production process operation analysis is carried out to determine the actual operation process parameters corresponding to each production process;

[0060] Based on the actual operation process parameters, the operation state of each production process is controlled, and the actual operation information of each production process is obtained; based on the actual operation information, the operation state of each production process is adjusted, and the adjusted operation process parameters of each production process are obtained;

[0061] The finished products obtained from actual production are tested to determine whether they meet the preset requirements for finished product size and shape; the operating process parameters of all adjusted production processes corresponding to the finished products that meet the preset requirements for finished product size and shape are integrated to obtain the full process parameters.

[0062] The beneficial effects of the above embodiments are as follows: the process design and implementation control method for outer square inner circle products obtains the finished product specification parameters corresponding to the outer square inner circle products based on the design drawing parameters and actual processing parameters of the outer square inner circle products, thereby determining the actual operating process parameters corresponding to each production process, which serve as a basis for setting the initial operating state of each production process; based on the actual operating process parameters, controlling the operating state of each production process and obtaining the actual operating information of each production process, thereby adjusting the operating state of each production process to ensure that the production process implements the corresponding production operation with the most matching operating process parameters; detecting and judging whether the finished products actually produced meet the preset finished product size and shape requirements, and integrating the adjusted operating process parameters of all production processes into full-process parameters, adjusting the process parameters of the outer square inner circle products from the design stage and the actual production stage, and obtaining the full-process parameters that can guide subsequent actual production through a single design and actual production test, thereby improving the design and production accuracy and repeatability of outer square inner circle products.

[0063] In another embodiment, based on the design drawing parameters and actual processing parameters of the outer square inner circle product, the finished product specification parameters corresponding to the outer square inner circle product are obtained; based on the finished product specification parameters, the production process operation analysis is performed to determine the actual operation process parameters corresponding to each production process, including:

[0064] Based on the design drawing parameters of the outer square inner circle product, a three-dimensional design model of the outer square inner circle product is constructed, and a three-dimensional contour feature of the three-dimensional design model is obtained; wherein the three-dimensional contour feature includes the three-dimensional dimensions and tolerances of the outer square part and the inner circle part of the three-dimensional design model;

[0065] The three-dimensional contour feature is compared with the actual processing accuracy parameters of the outer square part and the inner circle part of the production line to obtain the finished product specification parameters corresponding to the outer square inner circle product; wherein the finished product specification parameters include the size range parameters of the outer square part and the inner circle part in the finished product corresponding to the outer square inner circle product;

[0066] Obtaining the production process information of the production line regarding the outer square part and the inner circle part; wherein the production process information includes the type and motion parameters of the production process operation for processing and forming the outer square part and the inner circle part; comparing the production process information with the finished product specification parameters to determine the actual operation process parameters corresponding to each production process; wherein the actual operation process parameters include the motion amplitude and posture parameters corresponding to the cutting and / or stretching operations of each production process.

[0067] The beneficial effects of the above embodiments are that the production process of the outer square inner circle products such as the outer square inner circle special-shaped tube mainly includes the design stage and the actual production stage. Among them, the design stage requires the designer to construct the corresponding design drawings according to the product shape and size requirements; the actual production stage is to set the operating parameters of the production line according to the design drawings, so that the production line performs the corresponding product production operation process. In view of the structural irregularity and complexity of the outer square inner circle products, the production line includes multiple production processes that sequentially perform different types of production operations such as cutting and stretching. Correspondingly, the production operation type and action parameters performed by each production process are also different. In order to enable all production processes on the production line to accurately perform the corresponding production operations to obtain the outer square inner circle products matching the design drawings, it is necessary to compare the design drawings of the outer square inner circle products with the actual production processes of the production line, and determine the actual operation process of each production process in the production line in a targeted manner, so as to set the initial operation state of each production process, and ensure that the initial operation state of the entire production line basically matches the parameters of the design drawings. To this end, based on the design drawing parameters of the outer square inner circle products, a three-dimensional design model of the outer square inner circle products is constructed, and the three-dimensional contour features of the three-dimensional design model are obtained, and the three-dimensional dimensions and tolerances of the outer square part and the inner circle part of the three-dimensional design model are accurately and comprehensively characterized. Limited by the actual processing accuracy of the production line itself, it cannot be guaranteed that the outer square inner circle products made by the production line are completely consistent with the design drawings, and there will inevitably be deviations between the two. In order to minimize the deviation between the above two, it is necessary to determine the actual movement amplitude and posture within the allowable variation range of the operation actions corresponding to all production processes in the production line, and ensure that the operation process of all production processes meets the molding requirements of the shape and size of the outer square inner circle products. Specifically, the three-dimensional contour feature and the actual processing accuracy parameters of the production line for the outer square part and the inner circle part are compared to obtain the size range parameters of the outer square part and the inner circle part of the finished product corresponding to the outer square inner circle product, which are used as the finished product specification parameters, and the production process information of the production line on the outer square part and the inner circle part is compared with the finished product specification parameters to determine the movement amplitude and posture parameters corresponding to the cutting and / or stretching operation corresponding to each production process, which is the basis for setting the initial operation state of each production process in the subsequent process.

[0068] In another embodiment, based on the actual operation process parameters, the operation state of each production process is controlled, and the actual operation information of each production process is obtained; based on the actual operation information, the operation state of each production process is adjusted, and the adjusted operation process parameters of each production process are obtained, including:

[0069] Based on the actual operation process parameters and the initial mechanical action state of each production process, the initial operation process parameters of each production process are determined to control the mechanical operation state of each production process; the actual mechanical operation process of each production process is visually identified to obtain the actual operation information of each production process; wherein the actual operation information includes the three-dimensional trajectory information of the actual mechanical action of each production process;

[0070] Based on the motion drift amplitude of the actual mechanical motion three-dimensional trajectory information contained in the actual operation information, the mechanical operation state of each production process is adjusted, and the motion amplitude and posture parameters corresponding to the adjusted mechanical operation of each production process are obtained.

[0071] The beneficial effect of the above embodiment is that all production processes within the production line perform different types of operations respectively, and the action state of each production process performing the operation directly affects the shape and size of the outer square inner circle product. In order to ensure that each production process can accurately perform the corresponding operation, based on the actual operation process parameters and the initial mechanical action state of each production process (such as the initial action state of the mechanical parts corresponding to each production process), the initial operation process parameters of each production process are set to be consistent with the actual operation process parameters, so as to control the mechanical operation state of each production process, and ensure that the mechanical parts corresponding to each production process can have the action amplitude and posture parameters corresponding to the cutting and / or stretching operation at the beginning of the working stage. At the same time, the actual operation process of the mechanical parts corresponding to each production process is visually identified to obtain the actual mechanical action three-dimensional trajectory information of each production process, and the actual action of the mechanical parts performing the corresponding operation is fully characterized. The mechanical components of each production process are affected by their own internal factors and external environmental factors. The movement of the mechanical components will inevitably lead to unstable movements such as motion drift. In order to improve the movement stability of the mechanical components, the mechanical operation state of each production process is adjusted (for example, the closed-loop feedback working state of the mechanical components of each production process is adjusted) based on the motion drift amplitude of the actual mechanical motion three-dimensional trajectory information contained in the actual operation information. At the same time, the motion amplitude and posture parameters corresponding to the mechanical operation of each production process after adjustment are obtained to comprehensively and quantitatively characterize the mechanical operation movements of each production process.

[0072] In another embodiment, adjusting the operating state of each production process based on the actual operation information includes:

[0073] Step S1, using the following formula (1), according to the operating status of each production process, obtain the operating status value of each production process,

[0074]

[0075] In the above formula (1), S irepresents the operating state value of the i-th production process, that is, the overall performance state value of the process; P i represents the actual process parameter of the i-th production process, which may be, but is not limited to, temperature or pressure; max represents the maximum process parameter of the ith production process, that is, the best process value that can be achieved in the ith production process; Q i represents the actual quality parameter of the i-th production process, which may be but is not limited to product weight or size; Q max represents the maximum quality parameter of the ith production process, that is, the best quality standard that the ith production process can produce; T i represents the actual time parameter of the i-th production process, that is, the time required to complete the i-th production process; T max represents the maximum time parameter of the ith production process, that is, the shortest time required for the ith production process under ideal conditions; W P +W Q +W T represents the total weight coefficient, which reflects the combined influence of all parameters, and W P , W Q , W T Respectively represent the weight coefficients corresponding to process parameters, quality parameters, and time;

[0076] Step S2, using the following formula (2), based on the operation status value of each production process, generate the operation information feedback of each production process,

[0077]

[0078] In the above formula (2), F i represents the actual operation information feedback value of the i-th production process, which represents the feedback effect of the i-th production process; M i represents the target operating state value of the i-th production process, that is, the operating state value achieved under ideal conditions; α represents the first adjustment coefficient, which represents the degree of influence of the difference between the target operating state and the current state on the feedback value; E i represents the actual external environmental parameter of the i-th production process, which may be, but is not limited to, temperature or humidity; E0 represents the target external environmental parameter of the i-th process, that is, the standard value of the external environmental parameter under ideal conditions; β represents the second adjustment coefficient, which characterizes the degree of influence of the external environmental parameter deviation on the feedback value; γ represents the weight coefficient of the sine function; It means that the sine function is introduced to reflect the nonlinear influence of external environmental parameters on the operating state;

[0079] Step S3, using the following formula (3), adjust each production process according to the feedback value of the operation information of each production process,

[0080]

[0081] In the above formula (3), C i represents the control adjustment value of the i-th production process, that is, the amount of adjustment required; δ represents the control coefficient, which represents the actual operation information feedback value F i The actual operation information target feedback value R i The impact of the differences between R i represents the actual operation information target feedback value of the i-th production process; ∈ represents the adjustment factor, which represents the actual operation information feedback value F i The actual operation information target feedback value R i The influence of the absolute error between |F i -R i |Indicates the actual operation information feedback value F i The actual operation information target feedback value R i The absolute error between

[0082] If the control adjustment value C i If the preset threshold is exceeded, the operating process parameters of the i-th production process are adjusted, and the operating process parameters may be but are not limited to temperature or pressure; otherwise, the operating process parameters of the i-th production process are kept unchanged.

[0083] The beneficial effect of the above embodiment is that the above formula (1) is used to obtain the operation state value of each production process according to the operation state of each production process, and each step of the process state is analyzed in detail to make the state calculation more comprehensive and accurate; then the above formula (2) is used to generate the operation information feedback of each production process according to the operation state value of each production process, thereby providing a quantitative basis for subsequent control; then the above formula (3) is used to adjust each production process according to the operation information feedback value of each production process, and by modeling the dynamic relationship between the operation state, feedback information and control adjustment, an innovative control method is provided, which can optimize the operation state of the production process and improve production efficiency and product quality. This system can realize closed-loop control and ensure the flexibility and adaptability of the production process.

[0084] In another embodiment, the finished product actually produced is tested to determine whether the finished product meets the preset finished product size and shape requirements; the operating process parameters of all adjusted production processes corresponding to the finished product that meets the preset finished product size and shape requirements are integrated to obtain the full process parameters, including:

[0085] Performing three-dimensional visual recognition on the finished product actually produced to obtain three-dimensional size and shape information of the finished product; wherein the three-dimensional size and shape information includes the three-dimensional size and shape of the outer square part and the inner circle part of the finished product, and the relative three-dimensional spatial position relationship between the outer square part and the inner circle part of the finished product; based on the three-dimensional size and shape information, judging whether the finished product meets the preset finished product size and shape requirements;

[0086] Based on the execution sequence of all adjusted production processes corresponding to the finished products that meet the preset finished product size and shape requirements, the operating process parameters of all adjusted production processes are integrated to obtain the full process parameters.

[0087] The beneficial effect of the above embodiment is that all production processes within the production line will be updated and changed after the mechanical operation state is adjusted. In order to determine whether all production processes within the current production line can produce the final finished product of the outer square inner circle product that meets the requirements, it is necessary to perform three-dimensional visual recognition on the finished product actually produced to obtain the three-dimensional size and shape information of the finished product, and perform threshold comparison on the three-dimensional size and shape of the outer square part and the inner circle part contained in the three-dimensional size and shape information of the finished product, as well as the relative three-dimensional spatial position relationship between the outer square part and the inner circle part of the finished product, so as to determine whether the finished product meets the preset finished product size and shape requirements, and accurately determine whether the production line as a whole can currently produce qualified outer square inner circle products. Based on the execution timing of all adjusted production processes corresponding to the finished product that meets the preset finished product size and shape requirements, the operating process parameters of all adjusted production processes are integrated to obtain the full process parameters of the process, so that the full process parameters of the process that can guide the subsequent actual production can be obtained through a single design and actual production test, thereby improving the design and production accuracy and repeatability of outer square inner circle products.

[0094] The operation process parameter integration module is used to integrate the operation process parameters of all production processes adjusted corresponding to the finished product that meets the preset finished product size and shape requirements, and obtain the full process parameters.

[0095] The beneficial effects of the above embodiments are as follows: the process design and implementation control system for outer square inner circle products obtains the finished product specification parameters corresponding to the outer square inner circle products based on the design drawing parameters and actual processing parameters of the outer square inner circle products, thereby determining the actual operating process parameters corresponding to each production process, which serve as a basis for setting the initial operating state of each production process; based on the actual operating process parameters, the operating state of each production process is controlled and the actual operating information of each production process is obtained, thereby adjusting the operating state of each production process to ensure that the production process implements the corresponding production operation with the most matching operating process parameters; detects and determines whether the finished products actually produced meet the preset finished product size and shape requirements, and integrates the adjusted operating process parameters of all production processes into full-process parameters, adjusts the process parameters of outer square inner circle products from the design stage and the actual production stage, and obtains the full-process parameters that can guide subsequent actual production through a single design and actual production test, thereby improving the design and production accuracy and repeatability of outer square inner circle products.

[0096] In another embodiment, the finished product specification parameter determination module is used to obtain the finished product specification parameters corresponding to the outer square inner circle product based on the design drawing parameters and actual processing parameters of the outer square inner circle product, including:

[0097] Based on the design drawing parameters of the outer square inner circle product, a three-dimensional design model of the outer square inner circle product is constructed, and a three-dimensional contour feature of the three-dimensional design model is obtained; wherein the three-dimensional contour feature includes the three-dimensional dimensions and tolerances of the outer square part and the inner circle part of the three-dimensional design model;

[0098] The three-dimensional contour feature is compared with the actual processing accuracy parameters of the outer square part and the inner circle part of the production line to obtain the finished product specification parameters corresponding to the outer square inner circle product; wherein the finished product specification parameters include the size range parameters of the outer square part and the inner circle part in the finished product corresponding to the outer square inner circle product;

[0099] The actual operation process parameter determination module is used to perform production process operation analysis based on the finished product specification parameters to determine the actual operation process parameters corresponding to each production process, including:

[0100] Obtaining the production process information of the production line regarding the outer square part and the inner circle part; wherein the production process information includes the type and motion parameters of the production process operation for processing and forming the outer square part and the inner circle part; comparing the production process information with the finished product specification parameters to determine the actual operation process parameters corresponding to each production process; wherein the actual operation process parameters include the motion amplitude and posture parameters corresponding to the cutting and / or stretching operations of each production process.

[0101] The beneficial effects of the above embodiments are that the production process of the outer square inner circle products such as the outer square inner circle special-shaped tube mainly includes the design stage and the actual production stage. Among them, the design stage requires the designer to construct the corresponding design drawings according to the product shape and size requirements; the actual production stage is to set the operating parameters of the production line according to the design drawings, so that the production line performs the corresponding product production operation process. In view of the structural irregularity and complexity of the outer square inner circle products, the production line includes multiple production processes that sequentially perform different types of production operations such as cutting and stretching. Correspondingly, the production operation type and action parameters performed by each production process are also different. In order to enable all production processes on the production line to accurately perform the corresponding production operations to obtain the outer square inner circle products matching the design drawings, it is necessary to compare the design drawings of the outer square inner circle products with the actual production processes of the production line, and determine the actual operation process of each production process in the production line in a targeted manner, so as to set the initial operation state of each production process, and ensure that the initial operation state of the entire production line basically matches the parameters of the design drawings. To this end, based on the design drawing parameters of the outer square inner circle products, a three-dimensional design model of the outer square inner circle products is constructed, and the three-dimensional contour features of the three-dimensional design model are obtained, and the three-dimensional dimensions and tolerances of the outer square part and the inner circle part of the three-dimensional design model are accurately and comprehensively characterized. Limited by the actual processing accuracy of the production line itself, it cannot be guaranteed that the outer square inner circle products made by the production line are completely consistent with the design drawings, and there will inevitably be deviations between the two. In order to minimize the deviation between the above two, it is necessary to determine the actual movement amplitude and posture within the allowable variation range of the operation actions corresponding to all production processes in the production line, and ensure that the operation process of all production processes meets the molding requirements of the shape and size of the outer square inner circle products. Specifically, the three-dimensional contour feature and the actual processing accuracy parameters of the production line for the outer square part and the inner circle part are compared to obtain the size range parameters of the outer square part and the inner circle part of the finished product corresponding to the outer square inner circle product, which are used as the finished product specification parameters, and the production process information of the production line on the outer square part and the inner circle part is compared with the finished product specification parameters to determine the movement amplitude and posture parameters corresponding to the cutting and / or stretching operation corresponding to each production process, which is the basis for setting the initial operation state of each production process in the subsequent process.

[0102] In another embodiment, the production process operation control module is used to control the operation state of each production process based on the actual operation process parameters and obtain the actual operation information of each production process, including:

[0103] Based on the actual operation process parameters and the initial mechanical action state of each production process, the initial operation process parameters of each production process are determined to control the mechanical operation state of each production process; the actual mechanical operation process of each production process is visually identified to obtain the actual operation information of each production process; wherein the actual operation information includes the three-dimensional trajectory information of the actual mechanical action of each production process;

[0104] The production process operation adjustment module is used to adjust the operation state of each production process based on the actual operation information, and obtain the adjusted operation process parameters of each production process, including:

[0105] Based on the motion drift amplitude of the actual mechanical motion three-dimensional trajectory information contained in the actual operation information, the mechanical operation state of each production process is adjusted, and the motion amplitude and posture parameters corresponding to the adjusted mechanical operation of each production process are obtained.

[0106] The beneficial effect of the above embodiment is that all production processes within the production line perform different types of operations respectively, and the action state of each production process performing the operation directly affects the shape and size of the outer square inner circle product. In order to ensure that each production process can accurately perform the corresponding operation, based on the actual operation process parameters and the initial mechanical action state of each production process (such as the initial action state of the mechanical parts corresponding to each production process), the initial operation process parameters of each production process are set to be consistent with the actual operation process parameters, so as to control the mechanical operation state of each production process, and ensure that the mechanical parts corresponding to each production process can have the action amplitude and posture parameters corresponding to the cutting and / or stretching operation at the beginning of the working stage. At the same time, the actual operation process of the mechanical parts corresponding to each production process is visually identified to obtain the actual mechanical action three-dimensional trajectory information of each production process, and the actual action of the mechanical parts performing the corresponding operation is fully characterized. The mechanical components of each production process are affected by their own internal factors and external environmental factors. The movement of the mechanical components will inevitably lead to unstable movements such as motion drift. In order to improve the movement stability of the mechanical components, the mechanical operation state of each production process is adjusted (for example, the closed-loop feedback working state of the mechanical components of each production process is adjusted) based on the motion drift amplitude of the actual mechanical motion three-dimensional trajectory information contained in the actual operation information. At the same time, the motion amplitude and posture parameters corresponding to the mechanical operation of each production process after adjustment are obtained to comprehensively and quantitatively characterize the mechanical operation movements of each production process.

[0107] In another embodiment, the finished product detection and judgment module is used to detect the finished product actually produced to determine whether the finished product meets the preset finished product size and shape requirements, including:

[0108] Performing three-dimensional visual recognition on the finished product actually produced to obtain three-dimensional size and shape information of the finished product; wherein the three-dimensional size and shape information includes the three-dimensional size and shape of the outer square part and the inner circle part of the finished product, and the relative three-dimensional spatial position relationship between the outer square part and the inner circle part of the finished product; based on the three-dimensional size and shape information, judging whether the finished product meets the preset finished product size and shape requirements;

[0109] The operation process parameter integration module is used to integrate the operation process parameters of all production processes adjusted corresponding to the finished product that meets the preset finished product size and shape requirements, and obtain the full process parameters, including:

[0110] Based on the execution sequence of all adjusted production processes corresponding to the finished products that meet the preset finished product size and shape requirements, the operating process parameters of all adjusted production processes are integrated to obtain the full process parameters.

[0111] The beneficial effect of the above embodiment is that all production processes within the production line will be updated and changed after the mechanical operation state is adjusted. In order to determine whether all production processes within the current production line can produce the final finished product of the outer square inner circle product that meets the requirements, it is necessary to perform three-dimensional visual recognition on the finished product actually produced to obtain the three-dimensional size and shape information of the finished product, and perform threshold comparison on the three-dimensional size and shape of the outer square part and the inner circle part contained in the three-dimensional size and shape information of the finished product, as well as the relative three-dimensional spatial position relationship between the outer square part and the inner circle part of the finished product, so as to determine whether the finished product meets the preset finished product size and shape requirements, and accurately determine whether the production line as a whole can currently produce qualified outer square inner circle products. Based on the execution timing of all adjusted production processes corresponding to the finished product that meets the preset finished product size and shape requirements, the operating process parameters of all adjusted production processes are integrated to obtain the full process parameters of the process, so that the full process parameters of the process that can guide the subsequent actual production can be obtained through a single design and actual production test, thereby improving the design and production accuracy and repeatability of outer square inner circle products.

[0112] In general, the process design and implementation control method and system of the outer square inner circle product obtains the finished product specification parameters corresponding to the outer square inner circle product based on the design drawing parameters and actual processing parameters of the outer square inner circle product, so as to determine the actual operating process parameters corresponding to each production process, which serve as the basis for setting the initial operating state of each production process; based on the actual operating process parameters, the operating state of each production process is controlled and the actual operating information of each production process is obtained, so as to adjust the operating state of each production process to ensure that the production process implements the corresponding production operation with the most matching operating process parameters; detects and determines whether the finished product actually produced meets the preset finished product size and shape requirements, and integrates the adjusted operating process parameters of all production processes into the full process parameters of the process, adjusts the process parameters of the outer square inner circle product from the design stage and the actual production stage, and obtains the full process parameters of the process that can guide the subsequent actual production through a single design and actual production test, thereby improving the design and production accuracy and repeatability of the outer square inner circle product.
