The hot shaping optical module mold plays a crucial role in the production process of the optical module, especially for ensuring the precise forming and fitting degree of the precision components inside the optical module.
[0003] Currently, there are still defects in the operation methods of traditional hot shaping optical module molds. On the one hand, during the temperature rise process, the upper and lower modules often adopt an asynchronous temperature rise method. This method is extremely likely to cause uneven thermal stress in the mold due to the temperature difference between the upper and lower modules, and then lead to problems such as internal structural stress concentration and warping deformation in the formed optical module, seriously affecting the optical and electrical performance of the optical module, and significantly increasing the failure rate of the product in subsequent communication tests. On the other hand, after the mold is processed, the separation operation of the upper and lower modules lacks precise synchronous control, which is prone to mechanical pulling during demolding, scratching and damaging the precision surface of the formed optical module, thus reducing the yield rate of the product.

Understanding the thermal expansion coefficient and other properties of the material can avoid problems such as deformation caused by temperature changes and improve the mold quality.
[0072] Among them, the mold of the optical module to be processed refers to the mold for manufacturing the optical module that will undergo a specific synchronous heating and separation process in the optical module production process. It is a mold used for thermal shaping of the precision components inside the optical module. This mold includes an upper module and a lower module. In the traditional operation mode, there are problems such as uneven thermal stress caused by asynchronous heating of the upper and lower modules and lack of precise synchronous control during separation; the material property data refers to various attribute information related to the material of the mold of the optical module to be processed, including but not limited to the thermal conductivity of the material, which determines the ability of the material to conduct heat and has a key impact on the heat transfer between the upper and lower modules of the mold during the heating process; the coefficient of thermal expansion, which is related to the change in the size of the mold when the temperature changes and helps to estimate the deformation of the mold caused by heating; and data such as the melting point and specific heat capacity of the material. Optionally, the acquisition of the material property data corresponding to the mold of the optical module to be processed can be achieved through experimental testing methods, such as tensile tests, thermal analysis experiments, etc.
[0073] Furthermore, based on the material property data, the present invention analyzes the heating application scenario corresponding to the mold of the optical module to be processed, can accurately adapt the heating power, determines the appropriate heating rate and power according to the thermal properties of the material, and avoids mold damage or optical module forming defects caused by improper heating.
[0074] Among them, the heating application scenario refers to a comprehensive consideration of key temperature nodes, material properties and other factors, and depicts a comprehensive and specific mold heating implementation plan covering heating equipment selection, heating rate setting, heating duration control, and temperature monitoring methods.
[0075] As an embodiment of the present invention, the analysis of the heating application scenario corresponding to the mold of the optical module to be processed based on the material property data includes: performing hierarchical analysis on the material property data to obtain a hierarchical data group; identifying sensitive attribute elements corresponding to each layer of data in the hierarchical data group; calculating the temperature adaptation values of the mold of the optical module to be processed under different heating methods based on the sensitive attribute elements; analyzing the internal heat transfer curve corresponding to the mold of the optical module to be processed based on the temperature adaptation values; extracting key temperature nodes from the internal heat transfer curve; and constructing the heating application scenario corresponding to the mold of the optical module to be processed based on the key temperature nodes.
[0076] Among them, the hierarchical data group refers to a set of hierarchical structured data formed by carefully dividing material property data according to criteria such as different property categories, influence degrees, or data sources. For example, it can be stratified by major categories such as thermophysical properties and mechanical properties. Under thermophysical properties, it is further subdivided into minor categories such as thermal conductivity and specific heat capacity. Each minor category contains corresponding data, which together constitute the hierarchical data group; the sensitive attribute element refers to the characteristic element represented by the key data in the hierarchical data group that is extremely sensitive to temperature changes and the heating process and can significantly affect the mold performance, molding quality, and the effects of heating and separation operations; the temperature adaptation value refers to the quantified value of the ideal temperature range and change rate that the optical module mold to be processed can withstand and adapt to under different heating methods such as conduction heating, radiation heating, and convection heating, in combination with material properties, through a specific algorithm or model; the internal heat transfer curve refers to a curve plotted with time as the horizontal axis and the temperature difference or heat transfer rate between different positions inside the mold as the vertical axis; the key temperature node refers to the temperature value corresponding to a special time point in the internal heat transfer curve that corresponds to key physical changes in the mold (such as the start of material phase change, sudden change in thermal stress, etc.), has a significant impact on the molding quality, or marks the conversion of the heating stage.
[0077] Furthermore, the hierarchical analysis of the material property data can be achieved through a classification method based on data characteristics. For example, by classifying and stratifying according to characteristics such as the physical meaning of the material property data and the influence degree on the heating process, the hierarchical data group can be obtained; the identification of the sensitive attribute elements corresponding to the data in each layer of the hierarchical data group can be achieved through the principal component analysis method. For example, the principal component analysis method can help find the principal components that contribute more to the data variance, and the material property elements corresponding to these principal components can be used as sensitive attribute elements; the calculation of the temperature adaptation value of the optical module mold to be processed under different heating methods can be achieved through the following calculation formula; the analysis of the internal heat transfer curve corresponding to the optical module mold to be processed can be achieved through the finite volume method. For example, the optical module mold to be processed is divided into multiple control volumes, and the finite volume method is used to calculate the temperature changes in each control volume, and then the internal heat transfer curve of the entire mold can be obtained; the extraction of the key temperature nodes in the internal heat transfer curve can be achieved through the peak detection algorithm. For example, when the material reaches the melting point in the heat transfer curve, the temperature will remain unchanged temporarily, forming a plateau, and the peak detection algorithm can be used to find the temperature value corresponding to this plateau, which is the key temperature node; the construction of the heating application scenario corresponding to the optical module mold to be processed can be achieved through optimization algorithms. For example, algorithms such as genetic algorithms and particle swarm optimization algorithms.
[0078] As an embodiment of the present invention, calculating the temperature adaptation value of the optical module mold to be processed under different heating methods based on the sensitive attribute elements includes:
[0079] Calculating the temperature adaptation value of the optical module mold to be processed under different heating methods by using the following formula:

[0081] Wherein, TA represents the temperature adaptation value of the optical module mold to be processed under different heating methods, n represents the number of elements corresponding to the sensitive attribute elements, i represents the quantity index corresponding to the sensitive attribute elements, represents the standard value of the i-th sensitive attribute element under a specific heating method, represents the measured value of the i-th sensitive attribute element during the actual heating process, represents the measurement error value of the i-th sensitive attribute element, t represents the heating time, represents the number of heating methods corresponding to different heating methods, j represents the quantity index corresponding to different heating methods, represents the heating power value corresponding to the j-th heating method, represents the temperature state ratio corresponding to the j-th heating method.
[0082] Specifically, the temperature adaptation value is a comprehensive consideration index used to evaluate the adaptability and tolerance of the optical module mold to be processed to temperature changes under different heating methods, as well as the impact of this adaptability on the mold performance and the molding quality of the optical module. It synthesizes the performance of various sensitive attribute elements of the mold material under different heating conditions and is a quantitative value that can reflect the overall temperature adaptability of the mold; the standard value refers to the ideal numerical range or specific value determined based on a large amount of experimental data, theoretical research, and industry experience, etc., for each sensitive attribute element under a specific heating method. It represents the target value that the sensitive attribute element should possess in order to enable the mold to achieve the best performance and the molding quality of the optical module under this heating method; the measurement error value refers to the deviation degree between the measurement result and the true value during the actual measurement of the sensitive attribute element due to reasons such as the accuracy limitation of the measuring instrument, the interference of the measurement environment (such as temperature fluctuations, electromagnetic interference, etc.), and operation factors, etc.; the heating time refers to the time length experienced from the start of the heating operation on the optical module mold to reaching a certain specific heating stage (such as the mold reaching the preset molding temperature, completing a certain heat treatment process step, etc.) or the end of the entire heating process; the heating power value refers to the power magnitude of the heating device providing heat to the optical module mold under a specific heating method. It determines the amount of energy input into the mold per unit time and directly affects the heating rate, temperature uniformity, and the final temperature level of the mold, etc. Different heating methods (such as resistance heating, induction heating, infrared heating, etc.) can have different heating power values; the temperature state ratio refers to the ratio of the time when the mold is in different temperature ranges or temperature states to the total heating time under a certain heating method. It is used to describe the relative duration distribution of each temperature stage during the entire heating process of the mold and can reflect the temperature change rhythm of the heating process and the influence weight of different temperature stages on the temperature adaptability of the mold.
[0083] According to the heating application scenario, the present invention configures the heating power parameters of the upper and lower modules corresponding to the optical module mold to be processed, which can ensure that the heating rhythms of the upper and lower modules are adapted, accurately reduce the temperature difference, greatly reduce the risk of uneven thermal stress, avoid structural defects in the optical module after molding, and ensure the stability of optical and electrical performance.
[0084] Among them, the upper and lower modules refer to two key parts in the hot shaping optical module mold structure that cooperate with each other to achieve hot pressing forming of the optical module components. The upper module is usually located above, responsible for applying a certain pressure and coordinating heat transfer. The lower module is located at the bottom, playing a role in supporting and jointly constructing a closed hot shaping space with the upper module. The two are closely fitted and linked to ensure that the optical module is precisely formed under precise thermal environment and pressure conditions. The heating power parameter refers to the energy supply index set to drive the upper and lower modules to achieve the expected heating effect, specifically covering the electric power value provided to each module per unit time, which is determined in detail based on material characteristics and heating application scenarios. For example, for mold materials with low thermal conductivity, a relatively high heating power can be configured to ensure that the module is heated to the appropriate temperature range within the specified time, so as to precisely control the hot shaping process. Optionally, configuring the heating power parameters of the upper and lower modules corresponding to the optical module mold to be processed can be achieved through finite element analysis tools, such as tools like ANSYS and COMSOL.
[0085] Furthermore, based on the heating power parameter, the present invention constructs a synchronous heating simulation environment corresponding to the optical module mold to be processed, which can predict in advance the temperature distribution during the heating process. Through simulation, the heating trajectories of the upper and lower modules at different powers can be visually seen, which helps to optimize the setting of the heating power parameter and avoid temperature non-uniformity caused by improper power in actual operation.
[0086] Among them, the synchronous heating simulation environment refers to a virtual environment constructed by simulation means for simulating the synchronous heating process of the optical module mold to be processed under the given heating power parameter. This environment considers various factors such as the material properties, geometric shape, heat conduction characteristics, and boundary conditions of the mold, and can real-time simulate the temperature changes of each part of the mold during the heating process, as well as the transfer and distribution of temperature inside the mold.
[0087] As an embodiment of the present invention, constructing the synchronous heating simulation environment corresponding to the optical module mold to be processed based on the heating power parameter includes: performing spectral analysis on the heating power parameter to obtain power spectral data; performing filtering processing on the power spectral data to obtain filtered spectral data; performing feature extraction on the filtered spectral data to obtain spectral feature vectors; setting the initial heating conditions corresponding to the optical module mold to be processed based on the spectral feature vectors; and constructing the synchronous heating simulation environment corresponding to the optical module mold to be processed based on the initial heating conditions.
[0088] Among them, the power spectrum data refers to the result obtained by performing spectrum analysis on the heating power parameter, which shows the distribution of the heating power at different frequencies. Specifically, the signal of the heating power changing with time is converted into a frequency-domain representation through methods such as Fourier transform, which contains information such as various frequency components and their corresponding power amplitudes; the filtered spectrum data refers to the spectrum data obtained after filtering the power spectrum data. The purpose of the filtering process is to remove noise or unwanted frequency components in the power spectrum data, so that the obtained data can better reflect the key information and main characteristics during the mold heating process; the spectrum feature vector refers to a vector composed of key features extracted from the filtered spectrum data that can characterize the mold heating characteristics. These features can include main frequency components, spectrum peak positions, spectrum bandwidths, power spectral densities, etc.; the initial heating condition refers to the temperature state of the optical module mold to be processed at the beginning of the synchronous heating simulation environment set based on the spectrum feature vector, which covers factors such as the thermal inertia of the mold. A suitable initial temperature is determined according to the mold heating characteristics reflected by the spectrum feature vector to more accurately simulate the actual heating process of the mold.
[0089] Furthermore, the spectrum analysis of the heating power parameter can be achieved through the fast Fourier transform method. For example, it can convert the heating power parameter signal in the time domain into power spectrum data in the frequency domain; the filtering process of the power spectrum data can be achieved through filtering algorithms. For example, algorithms such as median filtering and low-pass filtering; the feature extraction of the filtered spectrum data can be achieved through feature extraction models. For example, models such as Word2Vec and GloVe; the setting of the initial heating condition corresponding to the optical module mold to be processed can be achieved through a regression analysis model. For example, models such as linear regression models and neural networks; the construction of the synchronous heating simulation environment corresponding to the optical module mold to be processed can be achieved through environment construction tools. For example, tools such as ABAQUS and OpenFOAM.

[0094] Among them, the discrete temperature sequence refers to the temperature data of the upper and lower modules continuously recorded in the synchronous heating simulation environment, which is extracted according to a specific time interval or sampling rule to form a set of discrete and time-ordered temperature values; the temperature trend curve refers to a smooth curve with time as the horizontal axis, which outlines the general trend of temperature by applying a fitting algorithm (such as least squares fitting of a straight line or a polynomial curve) to the discrete temperature sequence; the temperature mutation points refer to the special points on the temperature trend curve where the slope suddenly changes greatly, the temperature value jumps sharply, and deviates from the normal change range of adjacent points. These points usually indicate abnormal situations during the heating process, such as instantaneous fluctuations in heating power, sudden changes in the heat conduction characteristics of the mold material, etc.; the temperature stage refers to the different time periods into which the entire heating process of the upper and lower modules is divided based on the temperature mutation points, and the temperature changes within each stage show relatively unified characteristics, such as the initial slow heating stage, the stable and rapid heating stage, the fine-tuning stage near the target temperature, etc.
[0095] Furthermore, the discretization of the data in the synchronous heating simulation environment can be achieved by the equidistant sampling method.

[0099] Among them, the temperature equilibrium degree is a comprehensive index used to measure the corresponding uniformity of the temperature distribution of the upper and lower modules during the heating process. It is calculated by considering the differences in the heating rates of the upper and lower modules at multiple temperature sampling points and combining the influencing factors and their weights of the heating rate parameter. The smaller this value, the better the temperature equilibrium of the upper and lower modules during the heating process, and vice versa.

[0101] Use the following formula to calculate the temperature equilibrium degree of the upper and lower modules during the heating process:
[0102]

The heating rate refers to the value of the temperature increase per unit time, which reflects the speed of the object's temperature rise. For the upper and lower modules, the heating rate is the speed at which the temperature of the upper module or the lower module changes with time at specific temperature sampling points. The influencing factors refer to various factors that can affect the heating rates of the upper and lower modules and thus affect the temperature equilibrium. These factors can include the material properties of the mold (such as thermal conductivity, specific heat capacity, etc.), the structural design of the mold (such as the thickness and shape of the upper and lower modules), the heating method (such as the position and power distribution of the heat source), and the surrounding environmental conditions (such as air flow and heat dissipation). The factor weight value refers to the value assigned to reflect the degree of influence of each influencing factor on the temperature equilibrium.

[0107] Among them, different initial temperature difference conditions refer to the temperature difference situations of the upper and lower modules or different parts of the optical module mold to be processed at the beginning of heating. These differences can be various different numerical combinations. For example, the initial temperature of the upper module is 20°C and the initial temperature of the lower module is 25°C. This is an initial temperature difference condition; or the initial temperature of the center part of the mold is 30°C and the initial temperature of the edge part is 28°C. This is also a different initial temperature difference condition. The synchronous heating effect refers to the synchronous degree and consistency performance of the temperature rise of each part of the mold (such as the upper and lower modules or different regions) during the heating process, which includes aspects such as whether the temperature rise rates are similar, whether the times to reach the target temperature are basically the same, and the change situation of the temperature difference between each part during the heating process. Optionally, analyzing the synchronous heating effect of the optical module mold to be processed under different initial temperature difference conditions can be achieved by multiple sets of comparative experiments. For example, by comparing the times when each part reaches the same target temperature under different initial temperature difference conditions, the change curves of the temperature difference during the heating process, etc., to analyze the synchronous heating effect.

[0111] Among them, the temperature increase quantification index refers to the digital representation of the synchronous temperature increase effect, which is calculated by comprehensively considering factors such as temperature difference and temperature increase rate difference. For example, calculating the standard deviation of the temperature increase rates at different positions, or the sum of the absolute values of the temperature differences between each position and the average temperature at a specific time point, etc.; the temperature-sensitive area refers to the area on the optical module mold to be processed that is significantly responsive to temperature changes, usually at the uneven temperature increase locations, such as where the temperature gradient is large and the temperature increase rate difference is obvious, like the corners of the mold, the combined parts of different materials, etc.; the strain gauge layout plan refers to the specific plan for reasonably arranging strain gauges within the temperature-sensitive area, which determines the number, position, and pasting direction of the strain gauges. For example, at the stress concentration points or key connection parts in the temperature-sensitive area, the strain gauges are pasted along the main stress direction to ensure accurate measurement of the mold deformation caused by temperature changes; the temperature-strain data set refers to the set of strain data collected by the strain gauges during the mold test, which changes with temperature. These data reflect the small deformations generated in the temperature-sensitive area due to temperature changes, covering the strain values of the strain gauges at different times and positions.
[0112] Furthermore, the quantitative evaluation of the synchronous temperature increase effect can be achieved through a quantitative evaluation tool, such as the built-in functions AVERAGE, STDEV, etc. in Excel; the division of the temperature-sensitive area corresponding to the optical module mold to be processed can be achieved through a method based on temperature gradient, such as measuring the temperatures at different positions of the mold and calculating the temperature differences between adjacent positions. The areas with larger temperature differences are often the temperature-sensitive areas; the arrangement of strain gauges in the temperature-sensitive area can be achieved through the equal-spacing arrangement method. For example, when the overall strain situation of the temperature-sensitive area is required, the method of arranging strain gauges at equal intervals can be adopted; the collection of the temperature-strain data set in the strain gauge layout plan can be achieved through the multi-round collection method. For example, each time the temperature is raised to the same termination temperature, the data of the strain gauges are collected, and a more comprehensive temperature-strain data set can be obtained under different initial conditions; the query of the thermal stress change situation of the optical module mold to be processed during the test can be achieved through a finite element analysis tool, such as tools like ANSYS, ABAQUS, etc.

[0115] Among them, the separation guiding device refers to a key component in the optical module mold, usually composed of guide posts, guide sleeves, and related positioning structures. After the optical module is produced, the upper and lower modules need to be separated to take out the product. The role of the separation guiding device is to provide a precise guiding path for the relative movement of the upper and lower modules during the module separation process, ensuring that they smoothly separate along a predetermined trajectory. Optionally, the adjustment of the separation guiding device corresponding to the upper and lower modules can be achieved through a genetic algorithm. For example, through the iterative process of the genetic algorithm, the optimal design scheme is searched to obtain a separation guiding device adapted to the thermal stress change.

[0121] Among them, the source of the factors refers to the origin of various factors that interfere with the synchronous heating and separation process of the upper and lower modules, which can cover multiple aspects. For example, equipment failures are due to equipment aging and improper maintenance; environmental factors may come from unstable temperature and humidity in the workshop and strong electromagnetic interference around; material property differences may be due to different raw material batches and lax quality control, etc.; the existing operation characteristics refer to the characteristics and manifestation forms presented in the current synchronous heating and separation operation of the upper and lower modules. For example, the heating rate, heating method, mechanical action characteristics during separation, and contact state between modules, etc.; the key operation identifiers refer to the marks made on those parts of the existing operation characteristics that have a greater impact on the synchronous heating and separation process and are more critical. These identifiers can be specific operation steps, operation parameters, or operation actions, etc. For example, a certain key temperature control point during the heating process, a specific mechanical movement trajectory during separation, etc.; the optimizable links refer to the operation steps or process parts that can be improved and enhanced by in-depth analysis of the key operation identifiers. For example, if it is found that the heating rate is too fast resulting in uneven thermal stress, then adjusting the heating rate is an optimizable link; or if it is found that there is a jam in the mechanical action during separation, optimizing the mechanical structure or adjusting the operation method is an optimizable link.
[0122] Further, the querying of the source of the factors corresponding to the interference factors can be achieved through an association rule mining algorithm.
