Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

When the combination of technical solutions results in contradictions or inability to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0023] In the prior art, in the field of precision manufacturing, it is often necessary to attach sheet-shaped functional materials to the surface of a substrate with a special-shaped curved surface. The traditional manual attachment method relies on the operator's experience. When facing a complex surface with a large curvature change or a region with minute features, it is difficult to ensure the attachment efficiency and accuracy. Especially in the manufacturing of optoelectronic devices, the decorative layer and the protective layer need to be closely attached to the curved surface structure of the temple or the frame. Manual operation is prone to generating bubbles or wrinkles, resulting in the deterioration of optical performance and the decrease in the product qualification rate.
[0024] To solve the above problems, the R & D personnel observed that the existing attachment devices are only applicable to flat or simple curved surfaces and cannot adapt to special-shaped surfaces with high complexity. By analyzing the material forming mechanism, it was found that rigid support and dynamic positioning are the key factors to ensure the attachment accuracy. Therefore, it was proposed to combine the forming component with the linear motion mechanism to achieve the adaptive forming of multi-form materials through modular design.
[0025] Therefore, please refer to Figure 1 and Figure 2 , this application proposes a flat material shaping mechanism, which includes a linear module 10 and at least one forming component 20. The forming component 20 includes a forming block 21 and a forming workpiece 22 installed on the slider of the linear module 10. The forming workpiece 22 is arranged adjacent to the forming block 21 and is used to attach the flat material to the forming block 21 so that it is shaped closely following the contour of the forming block 21.
[0026] Among them, the linear module 10 refers to a mechanical transmission device with high-precision linear displacement function, which can be specifically realized by a ball screw drive or a synchronous belt drive structure, and is used to drive the forming component 20 to move along a predetermined trajectory. The forming block 21 refers to a rigid support body with a target forming profile, which can be specifically processed and formed by aluminum alloy or engineering plastics, and its surface profile matches the special-shaped curved surface of the substrate to be adhered. The forming and processing part 22 refers to an auxiliary forming device for flattening materials, and is used to generate a binding force that makes the materials adhere to the forming block 21. The forming block 21 is detachably mounted on the slider. The flattened material is a graphite sheet or a heat sink.
[0027] The profile of the forming surface 21b of the forming block 21 matches the curved surface profile of the target area of the special-shaped shell substrate to be attached.
[0028] Specifically, the linear module 10 drives the forming component 20 to move to a preset station through the slider. After the forming and processing part 22 is started, a force is applied to the flattened material, and the material is adhered and fixed to the surface of the forming block 21 and completely fits its profile. The three-dimensional curved surface structure of the forming block 21 maintains the shape of the material through rigid support, and the linear module 10 can adjust the position of the forming component 20 to adapt to materials or substrates of different sizes. After the material is formed, it is transferred to the target substrate for attachment by a supporting manipulator.
[0029] Compared with the prior art, traditional manual attachment depends on the operator's experience and cannot guarantee the surface fitting degree and repeat accuracy. This solution realizes the mechanical positioning and automatic control of the material pre-forming process through the combination of the rigid forming block 21 and the linear module 10, and eliminates the deformation error caused by manual operation. The synergistic effect of the forming and processing part 22 and the forming block 21 enables the material to form a three-dimensional shape matching the target substrate before transfer, significantly reducing the adjustment difficulty of the subsequent attachment process, that is, improving the attachment efficiency and thus enhancing the attachment quality.
[0030] This application can effectively solve the problems of wrinkles and bubbles in the process of attaching to special-shaped curved surfaces, and improve the fitting accuracy between the optical film layer and complex substrates. The three-dimensional contour replication function of the forming block 21 ensures that the shape of the material is highly consistent with the target curved surface, and the adjustability of the linear module 10 supports the rapid switching production of multiple varieties of materials. This flattened material shaping mechanism is particularly suitable for the automatic mounting scenario of small special-shaped components such as the temple of AR glasses, significantly improving the production yield and efficiency.
[0031] Please refer to Figure 1 and Figure 2 In this application, it is further proposed that the forming block 21 is provided with at least one suction hole 21a, the forming and processing part 22 is a vacuum generator, and the vacuum generator is communicated with the suction hole 21a, and is used to make the suction hole 21a on the forming block 21 generate negative pressure so that the flattened material adheres to the forming block 21.
[0032] Among them, the air suction hole 21a refers to a through hole opened on the surface of the forming block 21, which is used to adsorb and flatten the material through negative pressure. Specifically, it can be realized by a microhole array. Its function is to make the material adhere evenly through the negative pressure distribution. The vacuum generator refers to a pneumatic component that can generate negative pressure. Specifically, it can be realized by a Venturi tube structure or a vacuum pump. A closed air path is formed with the air suction hole 21a through a connecting pipe, so as to form a stable adsorption force at the air suction hole 21a. The air suction hole 21a communicates with the vacuum generator through a connecting pipe provided in the forming block 21, and the connecting pipe forms a branch network inside the forming block 21.
[0033] Specifically, air suction holes 21a are arranged inside the forming block 21. When the vacuum generator is started, a negative pressure area is formed at the air suction holes 21a, and the flattened material is adsorbed to the surface of the forming block 21 and closely adheres to its contour. The negative pressure distribution covers the entire forming surface 21b through the evenly arranged air suction holes 21a, ensuring that the flattened material has no local detachment or wrinkling deformation. During this process, the vacuum generator adjusts the negative pressure intensity to adapt to flattened materials of different materials, such as optical films or flexible circuits.
[0034] Compared with the prior art, traditional manual attachment relies on the operator's experience to apply force, and it is easy to cause stretching deformation or insecure adhesion of the material due to uneven force application. Moreover, mechanical pressing devices are difficult to adapt to complex curved surfaces. This solution realizes automatic uniform negative pressure distribution through vacuum adsorption, enabling the material to be accurately attached to the shaped curved surface without manual intervention, especially suitable for the surface of a housing including a micro feature area.
[0035] Through the above technical solution, this application solves the problem that air bubbles, wrinkles or local detachment are likely to occur when the flattened material is attached to a complex curved surface, ensures that the material accurately adheres to the contour of the forming block 21, avoids unstable attachment quality caused by manual operation errors, and improves the attachment efficiency at the same time.
[0036] Please refer to Figure 1 and Figure 2 , this application further proposes that the forming block 21 has a forming surface 21b, and the forming surface 21b is the surface for attaching the flattened material; a plurality of air suction holes 21a are provided on the forming surface 21b, and the plurality of air suction holes 21a are evenly distributed.
[0037] Among them, the forming surface 21b refers to the surface area of the forming block 21 that is in direct contact with the flattened material. The forming surface 21b can adopt a plane, a curved surface or a composite geometric shape, and its contour matches the three-dimensional structure of the target product. The uniform distribution of the air suction holes 21a means that a plurality of holes are arranged in the area of the forming surface 21b according to a preset spacing rule or in an irregular spacing. Specifically, it can be realized by a matrix arrangement, a concentric circle arrangement or an equidistant or non-equidistant arrangement along the normal direction of the curved surface, and uniform coverage is formed by maintaining the consistency of the adjacent hole spacing.
[0038] Specifically, the forming surface 21b is configured as a contoured curved surface that matches the surface morphology of the irregular shell substrate. The suction holes 21a are evenly distributed across this contoured surface. When the vacuum generator is activated, negative pressure is applied to the flat material surface through the evenly distributed suction holes 21a, ensuring balanced suction force across areas of varying curvature, edge transitions, and subtle features. For example, negative pressure is simultaneously applied to both raised and recessed areas of the curved surface, preventing the material from detaching from the forming surface 21b or creating wrinkles due to insufficient localized suction force. For irregularly shaped surfaces with sharp inflections, the suction holes 21a are symmetrically distributed along the inflection line to ensure simultaneous material adhesion on both sides.
[0039] The evenly distributed suction holes 21a of the present application make the negative pressure intensity of each area of the forming surface 21b tend to be consistent, especially for the area with sudden change in curvature. By increasing the hole density per unit area to compensate for the attenuation of adsorption force caused by the curved surface morphology, it can eliminate bubbles, wrinkles or edge lift caused by insufficient local adsorption force during the attachment process of flat materials on complex curved surfaces, ensure that the material is tightly fitted on the surface of the special-shaped shell in the entire area, and improve the yield and molding accuracy of the curved surface attachment process.
[0040] See also Figure 1 and Figure 2 The present application further proposes that the flat material shaping mechanism also includes a positioning component 30, which is installed on the slider of the linear module 10 and is spaced apart from the forming component 20 for pre-positioning the flat material before forming.
[0041] In this embodiment, the positioning assembly 30 is a device that mechanically constrains the material to its spatial position, eliminating deviations during material transport. The positioning assembly 30 and the forming assembly 20 are arranged to maintain a specific spacing, which can be achieved through slider travel control. This spacing must be greater than the material length to prevent interference, ensuring that positioning and forming operations are performed separately.
[0042] Specifically, when the linear module 10 drives the slider, the positioning assembly 30 and the forming assembly 20 are synchronously moved to the processing station. After the material is conveyed to the positioning assembly 30, its centerline is aligned with the axis of the forming block 21. After positioning, the slider continues to drive the forming assembly 20 to move over the flat material for attachment and forming. During this time, the positioning assembly 30 remains stationary to avoid interfering with the forming process.
[0043] See also Figure 1 and Figure 2, the present application further proposes that the positioning assembly 30 includes a positioning platform 31 and at least two side push members 32. The positioning platform 31 is installed on the slider of the linear module 10; the two side push members 32 are installed on the positioning platform 31 and are located on both sides of the positioning platform 31 for defining both sides of the flat material.
[0044] In this embodiment, the positioning platform 31 refers to a support structure for carrying the flat material, which can be specifically implemented by a metal plate or an engineering plastic plate. Its position is adjusted through the slider of the linear module 10 to provide a stable placement reference for the flat material. The side push member 32 refers to a device for applying constraints to both sides of the flat material, which can be specifically implemented by a mechanical structure combining cylinder drive and elastic buffering. By synchronously acting on both sides, it forms a clamping limit on the material to prevent the material from laterally shifting during the forming process.
[0045] Specifically, after the positioning platform 31 moves to the preset station with the slider of the linear module 10, the flat material is placed on the surface of the positioning platform 31. The side push members 32 on both sides simultaneously push towards the material direction. Through the cooperation of the rigid push head 323 and the elastic member 322, a flexible clamping force is generated when contacting the material. The physical boundaries formed by the two push heads 323 limit the material within a predetermined area to ensure that the center of the material is aligned with the contour of the forming block 21. When the pre-positioning of the material is completed, the side push members 32 reset to release the constraint, and the linear module 10 drives the positioning platform 31 and the forming assembly 20 into the subsequent forming process.
[0046] Compared with the prior art, traditional manual positioning relies on the operator's visual adjustment and is easily affected by the deformation of the material edge or visual error, resulting in deviation of the attachment position. However, this solution forms a repeatable physical positioning reference on both sides of the material through a mechanized side push limiting structure, eliminating the uncertainty brought by human intervention. It realizes the precise pre-positioning of the flat material before forming, ensures the complete alignment of the center of the material with the contour of the forming block 21, avoids attachment wrinkles or edge warping caused by material offset, and provides stable initial position conditions for the subsequent vacuum adsorption or electrostatic forming process.
[0047] In some specific embodiments, vacuum adsorption holes or electrostatic adsorption devices are provided on the positioning platform 31 for adsorbing and fixing the flat material during the pre-positioning stage.
[0048] Please refer to Figure 1 and Figure 2 , the present application further proposes that each side push member 32 includes a side push cylinder 321 installed on the positioning platform 31. One end of the elastic member 322 is connected to the telescopic rod of the side push cylinder 321, and the push head 323 is connected to the other end of the elastic member 322 so that the push head 323 is movable relative to the side push cylinder 321.
[0049] In this embodiment, the side push cylinder 321 refers to a power device used to drive the push head 323 to perform linear movement. Specifically, a pneumatic linear actuator can be used to achieve this, and the extension and retraction of the telescopic rod are controlled by compressed air. The elastic member 322 refers to a connecting component with elastic deformation ability. Specifically, a helical spring or a rubber pad can be used to achieve this, and it is used to provide buffering and maintain a constant contact force when the push head 323 contacts the material. The push head 323 refers to the end component that directly contacts and pushes the flat material. Specifically, it can be made of metal or engineering plastic, and is flexibly connected to the side push cylinder 321 through the elastic member 322 to compensate for the position deviation of the material.
[0050] Specifically, the telescopic rod of the side push cylinder 321 is connected to the push head 323 through the elastic member 322. When the side push cylinder 321 is activated, the telescopic rod pushes the elastic member 322 and the push head 323 to move towards the material. The elastic member 322 undergoes compressive deformation after the push head 323 contacts the material, absorbs the impact force caused by the position deviation or uneven thickness of the material, and at the same time maintains the continuous contact pressure of the push head 323 on the material. The push head 323 can adaptively fine-tune its position under the flexible support of the elastic member 322 to ensure that both sides of the material are synchronously and evenly pressed, avoiding material offset or deformation caused by unilateral overload.
[0051] In this solution, by introducing the elastic member 322 as an intermediate buffer element, the push head 323 is equipped with an adaptive adjustment ability. While ensuring the positioning accuracy, it effectively avoids damage to the surface or internal structure of the material caused by rigid impact, eliminates the problem of uneven lateral pressure caused by material size error or positioning deviation, ensures that the material is accurately centered before entering the forming process, and at the same time avoids surface scratches or structural deformation caused by hard contact between the push head 323 and the material, improving the yield of the finished product.
[0052] Please refer to Figure 1 and Figure 2 , the present application further proposes that a flexible portion is provided on the side of the push head 323 facing away from the elastic member 322, and the flexible portion is used to contact the flat material.
[0053] The flexible portion refers to the area where the push head 323 directly contacts the flat material. Specifically, it can be achieved by covering with soft materials such as silicone, rubber or polyurethane. Its function is to buffer the contact pressure of the push head 323 on the flat material, avoid surface scratches or deformation of the material caused by rigid contact, and at the same time adapt to the edges of materials with different curved profiles through material deformation.
[0054] Since the flexible part has the ability of elastic deformation, it can automatically adjust the contact area according to the curvature change of the material surface during the contact process, avoiding damage to the material surface caused by local stress concentration. For example, when there are small concave and convex structures at the edge of the material, the flexible part can fill the gap by local compression to ensure a stable contact between the pusher 323 and the material. At the same time, the telescopic characteristic of the elastic part 322 allows the pusher 323 to produce a small amount of retraction after contacting the material, further reducing the risk of rigid impact.
[0055] Optionally, a sensor is provided on the pusher 323 or the flexible part for detecting whether it contacts a flat material or detecting the contact force.
[0056] In another embodiment, it is further proposed that the formed part 22 is an electrode body, and the electrode body is located on the side of the forming block 21 facing away from the flat material. The electrode body is used to generate a strong electrostatic field after being energized, so that the flat material is polarized and attached to the forming block 21.
[0057] Among them, the electrode body refers to a conductive component that can generate an electrostatic field by applying a voltage. Specifically, it can be realized by using a metal plate, a conductive coating or a graphene material, and a potential difference is formed by connecting a high-voltage power supply. The side of the forming block 21 facing away from the flat material refers to the relative direction of the contact surface between the forming block 21 and the material. Specifically, positioning can be realized by mechanical fixing or embedded installation to ensure that the electrode body maintains a preset distance from the forming block 21. The strong electrostatic field refers to an electric field environment where the electric field strength is sufficient to polarize non-conductive materials. Specifically, it can be realized by adjusting the voltage amplitude or the electrode spacing, so that the surface charges of the flat material are redistributed and an electrostatic adsorption force is generated.
[0058] Specifically, the electrode body forms a non-uniform electric field after being energized. When the flat material enters the action area of the electric field, the dielectric molecules inside it are polarized, generating induced charges opposite to the direction of the electric field. Since the forming block 21 is grounded or in a low-potential state, the polarized material is adsorbed to the surface of the forming block 21 under the action of electrostatic attraction and bends naturally along the contour of the forming block 21. During this process, the electric field strength can be dynamically adjusted according to the material thickness or material characteristics. For example, for thin film materials with a low dielectric constant, the voltage value can be appropriately increased.
[0059] Compared with the prior art, electrostatic adsorption can apply force uniformly on the entire surface without physical contact, especially suitable for materials with micropores or breathable materials. In addition, the penetration characteristic of the electrostatic field enables an effective adsorption force to be generated between the material and the forming block 21 without complete fitting, avoiding material stretching and deformation caused by mechanical pressing.
[0060] Optionally, the electrode body is a flat electrode or a curved electrode matching the contour of the forming block 21. The electrode body is connected to a high-voltage power supply, and the high-voltage power supply can adjust the output voltage and / or current.
[0061] Please refer to Figure 1 and Figure 2 , this application further proposes that the flat material shaping mechanism includes two forming components 20, the two forming components 20 are arranged at intervals, and each forming component 20 is used to form a flat material.
[0062] The two forming components 20 maintain a non-overlapping spatial relationship in the moving direction of the linear module 10, which can be specifically achieved by horizontal juxtaposition or vertical dislocation to ensure that the two components do not interfere with each other during operation. The two forming components 20 are driven by the linear module 10 to work alternately. When the picking suction nozzle 2 transfers the first type of flat material to the area of one of the forming components 20, this component makes the material adhere and form through vacuum adsorption or electrostatic action, while the other forming component 20 is in a standby state; after the first material is formed, the linear module 10 drives the other forming component 20 to move to the processing area to perform synchronous forming operations on the second type of material provided by the feeding suction nozzle 3. This alternating operation mechanism enables two different materials to be continuously processed in the same device. For example, in the manufacturing of AR glasses temples, the curved surface forming requirements of optical films and metal shielding layers can be processed simultaneously.
[0063] In some specific embodiments, the forming blocks 21 of the two forming components 20 can be configured with different curvature radii, that is, the forming blocks 21 of the two forming components 20 have different contour shapes for forming flat materials with different shapes respectively. For example: one of the forming blocks 21 is designed to adapt to the gradually changing curved surface on the inner side of the temple, and the other forming block 21 is adapted to the stepped curved surface on the outer side of the temple. The forming processing parts 22 can respectively adopt a vacuum generator and an electrode body, so that one forming component 20 uses negative pressure adsorption when processing breathable materials, and the other forming component 20 uses electrostatic adsorption when processing non-breathable materials.
[0064] Compared with the prior art, traditional equipment is limited by a single forming component 20. When processing multiple types of materials, it is necessary to repeatedly change the mold or adjust parameters, resulting in an extended processing cycle and a decrease in positioning accuracy. This solution realizes the continuous processing of two materials through a dual-component parallel architecture without the need for downtime adjustment. For example, in the AR glasses production line, the forming processes of optical films and touch sensors can be completed synchronously, avoiding equipment idling caused by process switching.
[0065] Please refer to Figure 1 and Figure 2, the present invention also provides a processing device, which includes a base 1, a material taking suction nozzle 2, a feeding suction nozzle 3, and a flat material shaping mechanism. The material taking suction nozzle 2 is movably connected to the base 1 and is used to suck the flat material to be formed; the feeding suction nozzle 3 is movably connected to the base 1 and is spaced from the material taking suction nozzle 2, and is used to suck the finished product after forming; the flat material shaping mechanism is installed on the base 1 and is used to form the flat material. The specific structure of the flat material shaping mechanism refers to the above-mentioned embodiments. Since this processing device adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.
[0066] The base 1 refers to the supporting structure that bears the main body of the device and is used to provide an installation reference and rigid support for other functional components. The material taking suction nozzle 2 refers to the end effector with an adsorption function, which can be specifically realized by a vacuum suction cup or an electromagnetic adsorption accessory combined with a robotic arm, and is used to transfer the material to be formed between the material storage area and the shaping station. The feeding suction nozzle 3 refers to an adsorption device symmetrically structured with the material taking suction nozzle 2, which can be specifically realized by a multi-degree-of-freedom robotic arm equipped with a vacuum generator, and is used to transfer the formed material to the discharging station. The flat material shaping mechanism refers to a composite device including a linear module 10 and a shaping component 20, and is used to form the flat material according to a preset curved surface contour. The material taking suction nozzle 2 and / or the feeding suction nozzle 3 is an end effector of a multi-degree-of-freedom robotic arm. The processing device further includes a control system, and the control system is used to coordinately control the actions of the material taking suction nozzle 2, the feeding suction nozzle 3, the linear module 10, the shaping workpiece 22, and the positioning component 30.
[0067] Specifically, the material taking suction nozzle 2 moves within the planar space covered by the base 1 through a movable connection structure, grabs the material to be formed from the material storage area and transfers it to the station where the flat material shaping mechanism is located. The flat material shaping mechanism drives the shaping component 20 to move through the linear module 10, makes the shaping block 21 contact the material, and at the same time uses vacuum adsorption or electrostatic field action to make the material adhere to the surface of the shaping block 21 to complete three-dimensional shaping. After the forming is completed, the feeding suction nozzle 3 takes out the finished product from the forming station and transfers it to the discharging area, realizing the continuous automatic processing of the material from material taking to forming and then to discharging.
[0068] Compared with the prior art, traditional processing devices usually require multiple independent devices to separately complete the material taking, forming, and discharging processes, resulting in the accumulation of multiple positioning errors of the material and a large floor area of the devices. This solution integrates the functions of material taking, forming, and discharging into a single device, and uses the movably connected suction nozzle assembly and the shaping mechanism to cooperate, reducing the number of material transfers and avoiding repeated positioning errors. In addition, the flat material shaping mechanism can select vacuum adsorption or electrostatic field forming methods according to different material characteristics, improving the adaptability to materials of different materials.
[0069] Through the above technical solutions, the present application realizes the full-process automatic processing of flat materials from material taking to forming and blanking, solving the problems of low efficiency and poor attachment accuracy in traditional manual operations. Through the coordinated control of the movable suction nozzle and the shaping mechanism, it is ensured that the material maintains accurate positioning during the transfer and forming processes, avoiding defects such as wrinkles or offsets caused by multiple manual interventions. The integrated design reduces the occupation of equipment space and is compatible with multiple forming methods at the same time, meeting the high-efficiency attachment requirements of complex curved surface shell substrates.
[0070] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
