Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of orthopedic insoles, and in particular to a method and device for evaluating the function of an additive manufacturing orthopedic insole. BACKGROUND

[0002] Additive manufacturing (3D printing) of personalized orthopedic insoles has become a widely used method for treating foot problems. Through precise design and additive manufacturing technology, personalized orthopedic insoles can effectively improve the pressure distribution of the foot bottom, reduce foot pain, correct foot disease problems, and help restore normal gait. The production process of personalized orthopedic insoles usually includes several important steps: taking shape, designing, manufacturing, evaluating and modifying, etc. Among them, the evaluation and feedback of the wearing effect are particularly important, as they directly determine the correction effect and comfort of the orthopedic insole. However, in the current additive manufacturing process of personalized orthopedic insoles, there are some significant challenges in the evaluation and modification stage, especially in the selection and fitting of test insoles.

[0003] One feature of additive manufacturing is that once the manufacturing is complete, the design of the insole becomes unchangeable, which means that if deficiencies in the design or incompatibility with user needs are found during the wearing test, it is necessary to re-enter the design link, modify, re-manufacture, and evaluate again; this process not only takes time, but also consumes additional materials each time it is re-manufactured, increasing costs.

[0004] To solve the limitation of unchangeable additive manufacturing, some researchers or hospital manufacturers, etc. try to achieve flexibility through a modular design, i.e. assembling multiple modular components into a test insole, which can be adjusted according to the configuration of the modules to more accurately adapt to different foot problems and correction needs. This modular insole is usually composed of multiple detachable and adjustable parts, which can be flexibly modified according to user feedback during wearing, but its problems cannot be ignored. Due to the splicing and connection between the components of the modular insole, the overall stability of the test insole may be affected, resulting in discomfort or instability during wearing. This instability may affect the accuracy of the orthopedic effect, especially in cases where precise support and pressure distribution are required.

[0005] In addition, during the production process of test insoles, due to the personalized needs of orthopedic insoles, the number of insoles generated is small, which also makes it extremely rare for automatic production test insole equipment, or it is mostly operated by hand. SUMMARY

Herein, the illustrative embodiments of the present application and the description thereof are used to explain the present application, but not as a limitation to the present application.

[0055] It should be emphasized that the term "comprises / comprising" as used herein means the presence of the stated features, elements, steps or components, but does not preclude the presence or addition of one or more other features, elements, steps or components.

[0056] Herein, it is also necessary to mention that, if not specially mentioned, the term "connection" as used herein can not only mean direct connection, but also mean indirect connection with an intermediate.

[0057] Hereinafter, the embodiments of the present application will be described with reference to the drawings. In the drawings, the same reference signs represent the same or similar components, or the same or similar steps.

[0058] To address or alleviate the problems of time-consuming, labor-intensive, and costly repetitive manufacturing of personalized orthopedic insoles during testing in existing technologies, this invention provides an insole molding base for manufacturing test insoles, as well as an automated molding system for test insoles. Based on the personalized orthopedic insole design provided by the orthotist, this invention can automatically assemble a suitable insole molding base, or automatically place an integrated insole molding component on the insole molding base and press it into a test insole of the desired specific shape through heating and pressurization.

[0059] The method and apparatus for evaluating the function of additively manufactured orthotic insoles of this invention provide an efficient, precise, and automated solution for the production of test insoles. Through automated operating devices, heating and pressurizing devices, combined with precise component selection from the design model, personalized insoles that meet biomechanical requirements can be produced, making them widely applicable in medical, sports, and personalized customization fields.

[0060] In one aspect, the present invention provides an insole molding base for manufacturing test insoles, such as... Figure 1 and Figure 2 As shown, the manufacturing process of the test insole relies on precise component assembly and efficient molding technology, with the insole molding base being the key part of the entire insole molding system.

[0061] The base 210 is the basic structure of the insole. It can be made of rigid material and is used to support the shape of the entire insole. It supports all functional components (such as the orthotic component 220) and the insole molding component 230, ensuring that the insole has sufficient support and stability during compression molding. The design of the base 210 can be based on foot shape, gait, comfort, and other needs, combined with the requirements of foot orthotics.

[0062] Orthotic components 220 are additional parts designed to meet specific foot needs (such as plantar support, shock absorption, and arch correction). These components typically have different shape characteristics and can be individually selected and installed according to the patient's foot condition. Orthotic components 220 can be installed on the base 210 via magnetic adsorption, bonding, or snap-fit, serving to adjust foot pressure, improve gait, and provide comfortable support. For example, orthotic components 220 may include forefoot supports, medial arch supports, lateral arch supports, and heel cup supports zoned according to anatomical structure, and may also include metatarsal pads, transverse arch pads, and circular or elliptical shape modules for support and correction of specific foot problems.

[0063] The shoe insole forming piece 230 is a material and component for making a test shoe insole, which generates a test shoe insole by copying the surface shape of the shoe insole forming base. The shoe insole forming piece 230 is made of a plastic material, such as a low-temperature thermoplastic plate or EVA foam material, which has the ability to deform at a certain temperature and maintain the shape at room temperature. By copying the surface shape of the base, the test shoe insole meets the design requirements in appearance and function. In the case of using the same base 210, the shoe insole forming piece 230 can generally be reused, i.e. after each test is completed, it is flattened and the forming operation for the next test shoe insole is performed again.

[0064] The shoe insole forming piece 230 is a one-piece structure, compared to the assembled shoe insole in the prior art, the shoe insole forming plate has a smooth and continuous curved surface structure, which is more consistent with the shape of the shoe insole in daily use, optimizing the comfort, support and stability of the shoe insole, and also restoring the design model of the test shoe insole realistically. The press forming method simplifies the production process, reduces the cost, and can be customized according to user needs. The coherence of the overall structure, uniform pressure distribution and high-strength support make this design have significant advantages in foot correction and comfort.

[0065] On the other hand, the present application provides a device for evaluating the function of an additive manufacturing orthopedic shoe insole, as shown in Figure 3 and Figure 4 The device for evaluating the function of the additive manufacturing orthopedic shoe insole includes a control module, a component storage device 110, an operation table 120, a heating device 130, a pressurizing device 140, and an operation execution device 150, etc. The components include the above-mentioned base, orthopedic function piece, and shoe insole forming piece, etc.

[0066] The component storage device 110 includes a base storage area 111, an orthopedic function piece storage area 112, and a shoe insole forming piece storage area 113, and each component placed in each storage area can be obtained one by one by the operation execution device 150. The area division of each storage area can be scientific and reasonable, which can store various required components, and also should consider the acquisition path of the operation execution device 150, etc.

[0067] The control module is configured to obtain shape design parameters of the orthopedic insole from a design model of the orthopedic insole, and determine the selected base 210, orthopedic functional part 220 and insole forming part 230 according to the shape design parameters. The design model accurately generates components meeting the biomechanical requirements according to the foot requirements and orthopedic goals of the individual. The steps of selecting the base, orthopedic functional part and insole forming part can be performed by extracting the shape features and positions of feature points of the bottom contour, forefoot, medial arch, lateral arch and heel of the design model, and then using ICP (nearest point selection) registration, PointNet++, VoxelNet and other point cloud data-based target detection algorithms or CorrNet3D (unsupervised non-rigid point cloud registration network) to extract parameters and determine the most matching components to be used. The control module is in communication connection with the heating device 130, the pressing device 140 and the operation execution device 150 to control the execution of corresponding actions; for example, controlling the heating device 130 to turn on or off, or controlling the heating device to adjust the heating power; for example, controlling the movement of the pressing part of the pressing device 140 in the horizontal and vertical directions, and also controlling the movement speed and pressure size, etc.; for example, controlling the operation execution device 150 to obtain (which can be in the form of grabbing, adsorbing or pushing and pulling, etc.) the corresponding components in each storage area, and place them on the operation table. Optionally, the control module can be a computer host integrated with data input, algorithm program and sending control instructions and other functions.

[0068] The operation execution device 150 is configured to obtain the corresponding base 210 from the base storage area 111 based on the selected base, and place the base 210 on the operation table 120; and is also configured to obtain the corresponding orthopedic functional part 220 from the orthopedic functional part storage area 112 based on the selected orthopedic functional part, and fixedly install the orthopedic functional part 220 on the base 210. The base and at least one orthopedic functional part form an insole forming base; the operation execution device 150 is also configured to obtain the corresponding insole forming part 230 from the insole forming part storage area 113 based on the selected insole forming part, and place the insole forming part 230 on the insole forming base. After the test insole is prepared, or when it is necessary to prepare another improved test insole, the operation execution device 150 is also configured to move the base 210 and orthopedic functional part 220 on the operation table 120 back to the original position after the insole forming part 230 is formed and removed.

[0069] The heating device 130 is used to heat the selected insole forming piece to a set temperature. This heating process can ensure that the insole forming piece has sufficient plasticity and softness, so that it can accurately replicate the surface shape of the insole base in the subsequent pressing process. The heating device 130 can provide uniform temperature distribution to avoid molding problems caused by uneven heating.

[0070] The pressing device 140 is located above or on one side of the operation table 120, and is used to press the insole forming piece to replicate the surface shape of the insole forming base, thereby obtaining a test insole. The pressing device 140 functions to, after the insole forming piece is heated to an appropriate temperature, apply appropriate pressure to make the insole forming piece fully contact the surface of the base, so that the surface of the insole forming piece accurately replicates the shape of the base. This process ensures accurate replication of the surface shape of the insole by applying uniform pressure, thereby ensuring high precision of the test insole. The final test insole is used for subsequent testing and evaluation of the additive manufacturing orthopedic insole.

[0071] In the above embodiment, the device for evaluating the function of the additive manufacturing orthopedic insole in the embodiment of the present application can greatly improve production efficiency and reduce human operation errors through the fully automated operation execution device 150. The present application can quickly and accurately combine various functional modules of the insole, reducing the cumbersome process of traditional handmade insoles. The present application reduces human intervention and unnecessary steps through automation, which can significantly shorten the production cycle of the test insole. At the same time, the automated equipment can effectively reduce material waste and improve production efficiency. In addition, since the base, the orthopedic functional piece and the insole forming piece are all generated based on the design model of the orthopedic insole, the present application can customize personalized test insoles according to the foot conditions of different patients, and accurately match different functional evaluation requirements.

[0072] The device for evaluating the function of the additive manufacturing orthopedic insole in the embodiment of the present application provides an efficient, accurate and automated solution for the production of test insoles. Through the automated operation execution device 150, the heating and pressing device 140, combined with the accurate component selection of the design model, personalized insoles that meet the requirements of biomechanics can be produced, which can be widely used in the fields of medical treatment, sports and personalized customization.

[0073] It can be understood that the components in the embodiment of the present application do not depend on a certain specific production process or material, and suitable production methods (such as additive manufacturing, traditional mold manufacturing, etc.) can be selected for the manufacture of each component according to actual needs.

[0074] In some embodiments, during the forming process of the test insole, the substrate generally needs to be fixed on the operation table 120 to ensure that the substrate does not move or displace during the forming process of the insole. Whether it is heating, pressing or forming operation, the substrate needs to be kept stable and avoid interference from external forces. Therefore, the operation table 120 is provided with a substrate fixing mechanism for fixing the substrate during the forming process of the test insole and releasing the substrate after forming. After forming is completed, a convenient way is needed to release the substrate from the operation table 120 so as to take out the formed insole or for further processing. At this time, the release function of the substrate fixing mechanism is very important, which can ensure that the substrate is not damaged after the forming is completed.

[0075] As at least one implementation manner, the substrate fixing mechanism is a negative pressure adsorption mechanism, a clamping mechanism or a magnetic adsorption mechanism, the negative pressure adsorption mechanism or the magnetic adsorption mechanism is used for adsorbing from the bottom of the substrate, and the clamping direction of the clamping mechanism is along the length and / or width direction of the substrate.

[0076] Optionally, taking the negative pressure adsorption mechanism as an example, the negative pressure adsorption mechanism forms a low-pressure area at the bottom of the substrate, so that the substrate is adsorbed on the operation table 120. By controlling the negative pressure strength, the fixing strength of the substrate can be accurately controlled to avoid the substrate being too tight or too loose. The negative pressure adsorption can uniformly adsorb the entire substrate on the operation table 120, avoiding the substrate being fixed insecurely due to uneven local adsorption. The operation is relatively simple, and the fixing strength can be adjusted by adjusting the strength of the negative pressure, without complex mechanical structure. Since the negative pressure adsorption does not involve physical contact, the surface of the substrate can be prevented from being damaged or leaving scratches.

[0077] Optionally, taking the clamping mechanism as an example, the clamping mechanism can clamp along the length or width direction of the substrate through mechanical devices (such as air cylinders, springs, etc.), to ensure that the substrate does not displace during the forming process. The clamping can be realized by a clamp, which applies pressure along the edge, length or width direction of the substrate to firmly fix the substrate on the operation table 120. The clamping mechanism can provide strong fixing force, and is especially suitable for forming processes that require high fixing strength. The clamping mechanism can adjust the clamping force according to the needs, adapt to substrates of different thicknesses or materials, and ensure that the substrate is stable and not damaged. The clamping mechanism can be adjusted according to the specific size and shape of the substrate, and is suitable for different types of insole substrates.

[0078] Optionally, the magnetic adsorption mechanism is used as an example. The magnetic adsorption mechanism uses magnetic force to adsorb the substrate from the bottom of the base, so that it is firmly fixed on the operation table 120. The magnetic adsorption can be embedded with a magnet in the surface of the operation table 120 or use a magnetic material to build an adsorption area according to the needs. The substrate itself needs to contain ferromagnetic material. The magnetic adsorption mechanism can quickly adsorb and release the substrate in a short time, and the operation is very convenient. Due to the characteristics of magnetic adsorption, it does not need to be in direct contact with the substrate, so it can avoid damaging the surface of the substrate, and is especially suitable for high-precision and high-surface substrates.

[0079] In some embodiments, the design and configuration of the heating device 130 are both for the purpose of providing precise heat control during the insole forming process, so as to facilitate the shaping, softening or enhancing the physical properties of the insole forming piece. The specific heating scheme and heating position have an important influence on the effect and efficiency of the forming process.

[0080] Optionally, the heating device 130 is arranged in the insole forming piece storage area 113. The heating device 130 is arranged in each storage unit of the insole forming piece storage area 113, and the heating of each storage unit can be controlled individually, which is used for heating the selected insole forming piece. This mode can realize automatic management, heat a plurality of insole forming pieces in batches, and improve production efficiency; it can also reduce the time for making test insoles to a certain extent, that is, the heating process can be realized in the storage unit. This mode can also allow individual heating of the insole forming piece to meet the forming requirements of insole forming pieces of different materials or shapes. As another implementable mode, the heating device 130 includes a common heating block 131 (as shown in Figure 3 The heating block 131 is used to transfer the operation execution device 150 from the insole forming piece storage area 113 to the selected insole forming piece of the heating block 131 for heating. Compared with independent heating of each storage unit, the design of the common heating block can reduce the number of heating pieces and simplify the system structure. The heating block as a centralized heating area is convenient for unified control and monitoring of the heating process.

[0081] Optionally, the heating device 130 is arranged on the operation table 120, and the heating device 130 is used to heat the entire insole forming base and insole forming piece. Integrating the heating device 130 on the operation table 120 can reduce the occupied space of the equipment and facilitate the heating control of the operator. The heating device 130 can cover the entire or part of the operation table 120, which can uniformly heat the insole forming base and the insole forming piece, and ensure the temperature consistency during the heating process.

[0082] Optionally, the heating device 130 is arranged in each substrate 210 (as shown in Figure 2The heating device 130 is configured to heat the base and the insole forming piece. The design integrates the heating device 130 into each base to facilitate heating of the base and the insole forming piece. The base is an important part of the forming process, which can provide stable support and facilitate heating. Precise heating can be provided for different bases and insole forming pieces to ensure uniform and accurate temperature of each part.

[0083] Optionally, the heating device 130 is arranged on the pressing member of the pressing device 140 to directly heat the insole forming piece. In this way, heating and pressing are synchronized, which can form the insole while heating, reducing the time of heating and pressing, and improving efficiency. Synchronous heating during pressing helps to ensure uniform heating of the insole forming piece and avoid poor forming effect due to uneven heat distribution.

[0084] In the above embodiments, different heating device 130 configurations can be selected according to different process requirements and operation procedures. Separate control heating (heating of each storage unit inside the storage area) is suitable for scenarios with individualized requirements for different insole forming pieces. Public heating block is suitable for situations where the production process is simple, the number of insole forming pieces is small, or the shapes are consistent. The operation table 120 heating is suitable for large-scale production processes, providing uniform heating effect, but requiring higher space and equipment arrangement of the operation table 120. The base internal heating and the pressing member heating are suitable for efficient and precise control of heating, especially in the heat forming process that requires synchronous heating and pressing, which can improve production efficiency and forming precision.

[0085] In some embodiments, the device further comprises a cooling device 160 for cooling the formed insole forming piece; the cooling device 160 comprises a cooling fan arranged above or at least one side of the operation table 120, which is used to blow natural wind or cold wind. In these embodiments, the design of the cooling device 160 aims to quickly and effectively cool the formed insole forming piece to an appropriate hardness or stable state, so as to facilitate demolding from the base, subsequent processing and use. The cooling process is a key step in the insole forming process, which needs to ensure uniform cooling speed to avoid deformation or uneven material of the forming piece. The wind blown by the cooling fan can help to quickly reduce the temperature of the forming piece. By controlling parameters such as wind speed, wind direction, and wind temperature, the cooling speed can be adjusted to ensure the uniformity of the insole forming piece during the cooling process, preventing deformation or quality problems caused by uneven cooling.

[0086] When using air cooling, the cooling fan can be positioned above or at least to one side of the operating table 120. This positioning ensures that cool air is evenly distributed across the entire molding area, preventing defects in the molded parts caused by uneven cooling in certain areas. If the cooling fan is positioned above the operating table 120, cool air can naturally flow from above to the surface of the insole molded part, contributing to a more uniform temperature drop. Positioning the cooling fan to the side of the operating table 120 allows for adjustment of the airflow direction as needed, enabling targeted cooling to ensure effective cooling of specific areas of the insole molded part.

[0087] Cooling fans can blow either natural wind or cool air. Natural wind refers to air that has not undergone additional cooling treatment. It is suitable for scenarios where extremely rapid cooling is not required, or when the external ambient temperature is low; using natural wind for cooling can save energy. Cool air refers to air that has been processed by cooling equipment (such as air conditioning or refrigeration). This type of cool air is suitable for situations requiring rapid cooling, especially when insole molding parts need to be cooled quickly to ensure production efficiency and molding quality; cool air will be more effective in these cases. In other embodiments, other cooling methods can also be used, such as liquid cooling or compressed air cooling.

[0088] In some embodiments, such as Figure 4 As shown, the device for evaluating the function of additively manufactured orthotic insoles also includes a closed or open housing 101. A closed housing 101 helps maintain a clean and temperature-controlled working environment within the system, preventing dust, moisture, or external environmental factors from affecting the quality of the molded parts. An open design, on the other hand, helps improve ventilation, especially in scenarios requiring rapid cooling or air circulation. The component storage device 110 is located at the upper part of the housing 101, and the operating table 120 is located in the middle of the housing 101. This design allows the operating table 120 to easily connect the upper and lower component storage devices 110 and the insole outlet 103, facilitating effective management and processing. As the core component of the entire molding system, the operating table 120 is responsible for tasks such as placing raw materials, controlling the molding process, and processing the final molded parts. Its central location helps optimize workflow and ensures smooth transitions between different processes.

[0089] As at least one implementation manner, the base storage area 111 can be located on the left side of the upper part of the box 101, for storing base modules of different heights and sizes; the orthopedic functional part storage area 112 can be located in the middle position of the upper part of the box 101, for storing orthopedic functional parts of different types and different shape parameters; and the insole forming part storage area 113 can be located on the right side of the upper part of the box 101, for storing low-temperature thermoplastic plates of different sizes and shapes. Such a design can make the components to be used have a reasonable storage space in the system, thereby facilitating loading and unloading operations and not interfering with the work flow of other parts.

[0090] In some embodiments, as shown in Figure 4 The lower position of the box 101 is provided with an insole outlet 103, and the operation execution device 150 is further used to move the insole forming part demolded after forming and cooling to the insole outlet 103 position. After the insole forming part goes through the steps of forming, cooling, demolding, etc., it finally needs to be taken out or transported to the next process through the outlet position. The lower position can utilize the action of gravity, so that the forming part can automatically or easily move to the outlet after cooling, facilitating subsequent sorting or evaluation.

[0091] In the above embodiments, the design of the device for evaluating the function of the additive manufacturing orthopedic insole shows an efficient work flow, and by reasonably arranging the box 101, the storage device, the operation table 120, the cooling device 160 and the operation execution device 150, the production efficiency and the automation degree of the system can be greatly improved. The formed insole is quickly transferred from the operation table 120 to the insole outlet 103 by the precise handling system, and is prepared for subsequent processing and transportation. The entire system can adapt to different production demands, improve the production capacity and precision.

[0092] In some embodiments, the box 101 is further provided with an operation panel 102, which is used for manually inputting the design model of the test insole.

[0093] For example, the specific implementation process is as follows: (1) the user inputs the designed insole model on the operation panel 102. (2) The device for evaluating the function of the additive manufacturing orthopedic insole in the application automatically converts the insole model into component parameters of the base, orthopedic functional parts, etc. The mechanical arm (operation execution device 150) selects the corresponding components according to the component parameters in the left upper module storage area, places them on the operation table 120 with the heating device 130, and splices them as the insole forming base. (3) The mechanical arm selects the low-temperature thermoplastic plate (insole forming part) of the corresponding size according to the calculation parameters and places it at the insole forming base. (4) The heating device 130 starts to be powered on, controls the temperature of the base at about 60 degrees, and at the same time, the pressing device 140 repeatedly rolls on the surface of the low-temperature thermoplastic plate to make the low-temperature thermoplastic plate completely adhere to the surface of the base. (5) After the production is completed, the heating device 130 closes the heating function, opens the ventilation function, and quickly cools down to play the demolding role. (6) The mechanical arm puts the insole for testing (i.e., the insole forming part after forming) into the outlet area and puts the remaining components back into the storage area.

[0094] In other embodiments, the device for evaluating the function of the additive manufacturing orthopedic insole further comprises a data receiving module for automatically receiving the design model of the insole for testing. For example, the data receiving module can exchange data with an external computer system or design software through network connection, USB interface, or wireless communication, etc. In this design, the design model can be generated by a three-dimensional design software or a CAD system and directly transmitted to the device for evaluating the function of the additive manufacturing orthopedic insole through the data receiving module. This way can greatly reduce human input errors and achieve a more efficient production process. The design model can adopt standard data formats (such as CAD drawings, STL files, G codes, etc.), which contain detailed parameters required for forming, such as the geometry of the insole, the required material, the size, the thickness, etc.

[0095] In the above embodiments, the introduction of the operation panel 102 and the data receiving module makes the device for evaluating the function of the additive manufacturing orthopedic insole more flexible and efficient when dealing with different production tasks. The operation panel 102 provides a convenient manual input interface, which is suitable for customized production needs, while the data receiving module improves production efficiency through automation, reduces human errors, and adapts to batch production. The combination of the two can meet the diversified production needs, while improving the stability and intelligence level of the system.

[0096] In some embodiments, the pressure-applying member of the pressure device 140 comprises at least one of a pressure roller, a ball, a flexible plate, and a pressure bladder. In this design, the pressure-applying member of the pressure device 140 is used to apply uniform pressure to the test insole during the molding process, ensuring that the insole mold is accurately shaped according to the predetermined design model. Each pressure-applying member has different functions and characteristics, and can be selected or used in combination according to specific application requirements.

[0097] Optionally, the pressure roller is used to apply uniform pressure during the molding process, and is particularly suitable for continuous and efficient production processes. For example, during hot pressing, the pressure roller can uniformly press the insole material to ensure that the surface is flat and the thickness is uniform. The pressure roller can uniformly distribute pressure by rotating and rolling, avoiding excessive or insufficient local pressure. The pressure of the pressure roller can be adjusted by adjusting the rotation speed and pressure of the roller.

[0098] Optionally, the ball can be used as a pressure-applying member to precisely apply local pressure or uniformly distribute pressure, and is suitable for molding processes that require high precision. The use of balls can avoid large-area compression and is suitable for more complex and delicate molding requirements. Balls can provide more localized pressure and are suitable for more detailed and complex insole molding processes. The pressure applied by the ball is relatively soft, reducing damage to the material surface, and is suitable for production processes that require high surface quality.

[0099] Optionally, the flexible plate pressure-applying member is made of soft material and can adapt to the shape of the product. This type of flexible plate adapts to different insole designs by deforming, providing uniform and adaptive pressure distribution. Flexible plates can cover a large contact area and provide more uniform pressure distribution, making them suitable for processes that require high surface finish and uniformity.

[0100] Optionally, the pressure bladder adjusts the pressure by inflating or deflating, and is a very flexible pressure-applying method. The bladder can adjust the pressure as needed and uniformly distribute the pressure, and is commonly used in scenarios that require precise pressure control. The bladder can adapt to the surface profile of the object and adjust the intensity and uniformity of the applied pressure by changing the gas pressure. The pressure bladder can be equipped with an automated control system that can adjust the air pressure based on real-time feedback to ensure the accuracy of the pressure distribution.

[0101] In the above embodiments, different pressure-applying members can be selected or used in combination according to production requirements and product characteristics to achieve the best pressure-applying effect.

[0102] In some embodiments, the operation execution device 150 comprises a mechanical hand device with visual positioning. This configuration realizes precise positioning and automatic operation by integrating a visual positioning system (such as a camera and image processing algorithm) with a mechanical hand device (such as an industrial robot arm). The visual system guides the mechanical hand to perform precise grabbing, placing, assembling, etc. tasks by capturing images of the work area in real time. For example, the mechanical hand device can accurately identify the position of the insole forming piece through the visual positioning system, and then precisely move it to the required position to complete various complex operations such as assembly, disassembly or adjustment. The visual system can correct the positioning error of the mechanical hand in real time to ensure the accuracy of the operation. Through the computer vision system, different types of components and operation tasks can be quickly and flexibly handled. Complex shapes and highly variable work environments can be handled.

[0103] In some embodiments, the operation execution device 150 comprises a push rod arranged behind each component, a linear guide for moving the components from the push-out position to the operation table 120, and a mechanical hand for disassembling and assembling each component. This configuration realizes the movement, disassembly and precise positioning of components by using the push rod, linear guide and mechanical hand. The push rod is used to move the components from the storage position to the push-out position (such as the side where the operation table 120 is located), which can provide linear motion. The linear guide is used to move the components from the push-out position to a position close to the operation table 120. The mechanical hand is used for disassembly, handling, assembly, etc. operations, which realize the disassembly, handling and assembly of components through grabbing and placing.

[0104] In some embodiments, the device for evaluating the function of the additively manufactured orthopedic insole further comprises a temperature detection device for non-contact monitoring of the real-time temperature of the insole forming piece. During the molding process of the insole forming piece, if the real-time temperature of the insole forming piece monitored by the temperature detection device is lower than the set temperature, the heating device 130 is controlled to be turned on or the heat generation is increased to make the temperature of the insole forming piece reach the set temperature; during the cooling process after the insole forming piece is formed, if the real-time temperature of the insole forming piece monitored by the temperature detection device reaches the demolding temperature, the operation execution device 150 is controlled to remove the insole forming piece and throw it to the insole outlet 103 position.

[0105] In this embodiment, the device for evaluating the function of the orthopedic insole manufactured by additive manufacturing integrates multiple key components, aiming to achieve efficient and accurate management of the insole forming process through precise temperature control and automated operation. The temperature detection device is used to monitor the temperature of the insole forming piece in real time and non-contact manner. The temperature detection device can use infrared temperature sensors or laser temperature measurement technology, which can accurately sense the surface temperature of the insole forming piece without direct contact. If the temperature detection device detects that the temperature of the insole forming piece is lower than the set value, the system will automatically start or increase the heating amount, and the insole forming piece will be heated by the heating device 130 (such as an electric heater, a hot air gun, an infrared heater, etc.) to raise the temperature to the set forming temperature range. Ensure that the insole forming piece maintains an ideal temperature level throughout the forming process, thereby ensuring the plasticity, shape retention, and final forming quality of the material.

[0106] When the insole forming piece is completed, the system enters the cooling stage. In this process, the temperature detection device continues to monitor the temperature of the insole forming piece, and once the temperature drops to the demolding temperature (i.e., the temperature at which the mold can be safely removed), the next operation is triggered. The demolding temperature refers to the surface temperature of the insole forming piece during cooling, which is low enough to ensure that the forming piece can be smoothly removed without damage. Through precise temperature management, the insole forming piece has the best physical properties when demolding, reducing the rate of defective products.

[0107] The device for evaluating the function of the orthopedic insole manufactured by additive manufacturing achieves efficient and accurate temperature control management during the insole forming process through precise temperature detection and control. The close cooperation of the temperature detection device, the heating device 130, and the operation execution device 150 ensures that the forming piece is completed at an ideal temperature, while the automated pick-and-place system improves production efficiency.

[0108] In another aspect, the present application also provides a method for evaluating the function of the orthopedic insole manufactured by additive manufacturing, as shown in the following schematic diagram: Figure 5 The implementation of the method is based on the device for evaluating the function of the orthopedic insole manufactured by additive manufacturing described above, and the method further includes the following steps:

[0109] S10: The control module obtains the shape design parameters of the orthopedic insole from the design model of the orthopedic insole, and determines the selected base, orthopedic functional piece, and insole forming piece according to the shape design parameters. In this step, the control module can refer to the processor and controller of the device, etc., with functions such as data reception, calculation, and sending of control instructions. The shape design parameters of the orthopedic insole can include size, thickness, curve, etc. Through analysis of the design model, each component is accurately selected and configured to ensure that the test insole is prepared as close as possible to the design model of the orthopedic insole in terms of appearance and fidelity. The higher the shape restoration degree of the test insole, the better the data reliability of the evaluation of the function of the orthopedic insole manufactured by additive manufacturing.

[0110] S20: The control operation execution device acquires the corresponding base in the base storage area and places it on the operation table; the control operation execution device acquires the corresponding orthopedic functional part in the orthopedic functional part storage area and places it on the base of the operation table to form a shoe pad forming base; the control operation execution device acquires the corresponding shoe pad forming part in the shoe pad forming part storage area and places it on the shoe pad forming base. In this step, the base and the orthopedic functional part are assembled on the operation table according to the design requirements to build the forming base of the shoe pad, preparing for the subsequent forming and heating process. The path planning of the operation execution device, the grabbing and placing of the components, etc. can be controlled by the control module.

[0111] S30: The control heating device directly or indirectly heats the selected shoe pad forming part to a set temperature. In this step, heating the shoe pad forming part can make it soft, which is convenient for the subsequent forming and copying process. The setting of the heating temperature can be selected according to the characteristics of the material to ensure that the forming can be effectively carried out without damaging the material.

[0112] S40: The control pressure device performs pressure forming on the shoe pad forming part to make the shoe pad forming part tightly adhere to the upper surface of the shoe pad forming base and copy its shape to obtain a test shoe pad. Through pressure, the forming part completely copies the shape of the forming base, thereby generating a test shoe pad that can be used for functional evaluation. This step ensures that the design model of the orthopedic shoe pad can be accurately converted into a physical model to meet the expected functional requirements.

[0113] S50: After the test shoe pad is cooled, the control operation execution device takes it out and puts it into the shoe pad outlet. The cooling process makes the forming part stable and can retain its shape at room temperature. After the shoe pad is taken out, subsequent functional tests or other applications can be performed.

[0114] In addition to the application of test shoe pads in the field of personalized orthopedic shoe pads, the device for evaluating the function of additive manufacturing orthopedic shoe pads of the present application can also be widely applied in many fields such as sports shoes, medical shoe pads, fashion shoe pads, work shoe pads, special function shoe pads, shoe pad material research and development, shoe pad automatic production line, etc. Through automatic, personalized and precise temperature control management, the device can improve production efficiency, product quality and meet the diversified needs of shoe pads in different scenarios.
