[0098] VR (Virtual Reality) is characterized by immersion, interactivity, and imagination. AR (Augmented Reality) is a new human-computer interaction technology that allows users to interact with virtual objects in real time. These technologies are typically implemented using lenses, which render virtual images. Therefore, the optical performance of these lenses determines the user experience.
[0099] Figure 1 A schematic structural diagram of a curved lens 10 at one viewing angle in an embodiment of the related art is shown; Figure 2 A schematic structural diagram of a curved lens 10 at another viewing angle in an embodiment of the related art is shown; for ease of explanation, only content related to the embodiment of the related art is shown. Figure 1 One of the viewing angles is the side viewing angle of the curved lens 10, Figure 2 Another perspective in the figure is a top view of the curved lens 10.
[0100] Please refer to Figure 1 and Figure 2 In one embodiment of the related art, a curved lens 10 is provided. The curved lens 10 is a round 3D spherical lens. The curved lens 10 can be bonded to other types of lenses to form a lens assembly for use with corresponding wearable devices. Conventionally, the edges of the curved lens 10 produced by manufacturing may have certain defects, requiring a CNC (Computer Numerical Control) machine tool (e.g., a CNC cutting machine) to cut the edges of the curved lens 10.
[0101] Figure 3 A schematic structural diagram of a carrier 20 in an embodiment of the related art is shown; for ease of explanation, only contents related to the embodiment of the related art are shown.
[0102] Please refer to Figure 3 Taking the curved lens 10 as a circular 3D spherical lens as an example, before cutting the edge of the curved lens 10, it is necessary to use Figure 3 The carrier 20 shown in the figure carries and fixes the curved lens 10. Figure 3As shown in the figure, in one embodiment of the related art, the support surface 21 of the carrier 20 is a contoured surface that matches the surface of the curved lens 10 to facilitate support. The carrier 20 is also provided with a suction hole 22 extending through the support surface 21. The suction hole 22 is externally connected to a negative pressure line, which secures the curved lens 10 via vacuum suction. To improve sealing performance, the carrier 20 is also provided with a mounting groove 23, which contains a sealing ring m.
[0103] Figure 4 A schematic diagram showing a first use state of a carrier 20 carrying a curved lens 10 in an embodiment of the related art; Figure 5 A schematic diagram showing a second use state of a carrier 20 carrying a curved lens 10 in an embodiment of the related art is shown; Figure 6 A schematic diagram of a carrier 20 carrying a curved lens 10 in a third use state in an embodiment of the related art is shown; for ease of explanation, only content related to the embodiment of the related art is shown.
[0104] The inventors of this application have noticed that, on the one hand, it is difficult to control the size of the mounting groove 23 and the processing accuracy of the sealing ring m, which makes it difficult for the lower surface of the curved lens 10 to be in close contact with the supporting surface 21. Figure 4 As shown, the sealing ring m is also difficult to be in close contact with the lower surface of the curved lens 10 at the maximum contact surface. Figure 5 As shown, if the mounting groove 23 is too shallow, the lower surface of the curved lens 10 is difficult to contact the bearing surface 21, resulting in insufficient support and easily causing the curved lens 10 to deviate during processing. Figure 6 As shown, if the mounting groove 23 is too deep, the sealing ring m will have difficulty contacting the lower surface of the curved lens 10, resulting in the sealing ring m failing to perform its load-bearing and sealing functions. Furthermore, the carrier 20 is typically made of plastic or metal, and the hard contact between the carrier 20 and the curved lens 10 can easily cause scratches and other damage to the surface of the curved lens 10. Consequently, the appearance and optical performance of the curved lens 10 can be affected.
[0105] The inventors of this application further discovered that due to the high cutting force of CNC, it is difficult to stably adsorb the curved lens 10 by relying solely on the sealing ring m, which in turn causes the position of the curved lens 10 to shift during the cutting process, affecting the processing accuracy of the curved lens 10 contour. Figure 7 As shown, the first contour line L1 and the second contour line L2 are obtained by experiments using a coordinate measuring machine. The first contour line L1 is a standard contour line, and the second contour line L2 is an actual cutting contour line. It can be seen that the second contour line L2 is offset relative to the first contour line L1.
[0106] To address at least some of the aforementioned issues, the inventors of this application, after in-depth research, have improved the structure of the carrier to avoid the aforementioned risks associated with the sealing structure of the mounting groove and the sealing ring. The following describes the carrier provided in the embodiments of this application, in conjunction with the relevant drawings and some embodiments.
[0107] It should be noted that the carrier provided in the embodiments of the present application can be used to support and fix curved lenses, but is not limited to supporting and fixing other types of curved objects, such as curved cover plates. Such curved objects can be used in electronic devices such as wearable display devices and mobile phones, and the materials of such curved objects can be, but are not limited to, glass. The use of these devices can be based on specific usage scenarios, and the embodiments of the present application do not impose specific limitations on this.
[0108] Figure 8 A structural diagram of a viewing angle carrier 110 in an embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0109] In some embodiments, please refer to Figure 8 , combined with the reference shown later Figures 10 to 13 The embodiment of the present application provides a carrier 110, which includes a main body 111 and a plurality of elastic members 112. The main body 111 has a plurality of penetrating receiving holes along the first direction F1. Each elastic member 112 is filled in a receiving hole. The main body 111 and all the elastic members 112 form a bearing surface 110a along one side of the first direction F1. The bearing surface 110a is used to bear a curved object t along the first direction F1. The carrier 110 is provided with adsorption holes k penetrating the bearing surface 110a along the first direction F1. The adsorption holes k are used to adsorb and fix the curved object t.
[0110] Therefore, by using a main body 111 with a receiving hole and filling the elastic member 112 in the receiving hole, the main body 111 can increase the overall rigidity strength. Compared with the sealing ring in the related technology, the contact area t1 between the elastic member 112 in the receiving hole and the curved object t is larger, which can improve the sealing and friction, thereby improving the adsorption stability, thereby improving the damage and deformation of the curved object t, and improving the appearance quality and optical performance of the curved object t.
[0111] In some embodiments, the hardness of the main body 111 is greater than the hardness of the elastic member 112. In this way, the overall rigidity strength can be increased with the help of the main body 111, and the damage to the curved object t can be reduced with the help of the elastic member 112. For example, the material of the main body 111 is a polymer material. Optionally, a porous polymer material can be selected to utilize the porous characteristics of the material and fill the elastic member 112 in the pores of the material. In this case, the porous structure of the material constitutes a receiving hole. For another example, the material of the elastic member 112 can be a soft rubber material. In this case, the material of the main body 111 can be a hard rubber material, and the required receiving holes can be set on the main body 111. The selection can be made according to the actual use situation, and the embodiment of the present application does not impose specific restrictions on this.
[0112] In some embodiments, please refer to Figure 8 Multiple adsorption holes k are provided, and all adsorption holes k are evenly distributed on the supporting surface 110a. This avoids the aforementioned problem of difficult uniform distribution of adsorption holes k due to the need to create mounting grooves for the sealing ring. When the adsorption holes k are evenly distributed, the vacuum adsorption force can be more evenly distributed, which can improve the deformation of the curved object t caused by uneven adsorption force and enhance the imaging quality of the curved object t.
[0113] Figure 9 A structural diagram of a viewing angle carrier 110 in another embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0114] In some embodiments, please refer to Figure 9 The receiving hole is constructed as a hexagonal structure, and the main body 111 is a honeycomb porous structure, and the adsorption holes k are distributed on the carrying surface 110a. In this way, the overall structure can be made more uniform and the adsorption stability can be further improved.
[0115] Of course, it should be noted that the accommodating holes can be evenly distributed on the bearing surface 110a, or unevenly distributed on the bearing surface 110a. The accommodating holes can be the same size or different sizes. On the basis that the bearing surface 110a is composed of the main body 111 and the elastic member 112 on one side along the first direction F1, the adsorption holes k can be evenly distributed. The adsorption holes k can be located on the elastic member 112, or partially on the elastic member 112 and partially on the main body 111. The number of adsorption holes k can be set according to specific actual conditions, and this embodiment of the application does not impose any specific restrictions on this.
[0116] In some embodiments, please refer to Figure 8 and Figure 9The diameter d of the adsorption hole k is 1 mm to 3 mm. This not only reduces the risk of debris clogging the adsorption hole k during subsequent cutting processes due to a too small adsorption hole k, but also mitigates the risk of the curved object t's surface shape changing and affecting optical performance due to an overly large adsorption hole k. Alternatively, the diameter d of the adsorption hole k is 2 mm, which further enhances the ease of fabrication of the material transfer device 100.
[0117] Based on the same inventive concept, the present application also provides a material transfer device 100, including the carrier 110 in any of the above embodiments. Since the material transfer device 100 includes the carrier 110 in any of the above embodiments, it has the advantages mentioned above, which will not be repeated here.
[0118] Figure 10 A structural schematic diagram of a material moving device 100 from another perspective in an embodiment of the present application is shown; for ease of explanation, only content related to the embodiment of the present application is shown.
[0119] In some embodiments, please refer to Figure 10 The material moving device 100 further includes a limiting member 120. The limiting member 120 is configured to limit the curved object t in a first direction F1 and a second direction F2, wherein the first direction F1 and the second direction F2 are perpendicular to each other. Figure 10 As an example, the first direction F1 is a vertical direction and the second direction F2 is a horizontal direction.
[0120] In this way, the curved object t can be positioned by the limiting member 120 , thereby improving the horizontal position accuracy of the curved object t.
[0121] Figure 11 A schematic structural diagram of the position limiting member 120 in a first position is shown in an embodiment of the present application; Figure 12 A schematic structural diagram showing an embodiment of the present application in which the limiting member 120 is in the second position; Figure 13 A structural schematic diagram of the position limiting member 120 in an embodiment of the present application is shown in the third position; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0122] In some embodiments, please refer to Figures 10 to 13 The limiting member 120 is configured to be able to reciprocate in the first direction F1, and the limiting member 120 has a first position, a second position and a third position during the movement. Figure 11 As shown, the limiting member 120 is in the first position, and the limiting member 120 is used to support and limit the curved surface object t so that a gap is formed between the curved surface object t and the supporting surface 110a. Figure 12 As shown, the limiting member 120 is in the second position, and the limiting member 120 and the supporting surface 110a jointly support the curved surface object t. Figure 13As shown, the limiting member 120 is in the third position. The limiting member 120 is located below the plane where the supporting surface 110 a is located, and the limiting member 120 is separated from the curved object t located on the supporting surface 110 a.
[0123] Therefore, through the three positions of the limiter 120, the horizontal position of the curved object t can be limited by the limiter 120 first, and then the curved object t can be supported together by the limiter 120 and the supporting surface 110a. After the carrier 110 adsorbs and fixes the curved object t, the limiter 120 is retracted to the third position to avoid subsequent cutting or bonding processes.
[0124] In some embodiments, the material moving device 100 further includes a first position detecting member (not shown in the figure), a second position detecting member (not shown in the figure), and a third position detecting member (not shown in the figure). The first position detecting member is used to detect whether the position limiting member 120 is in the first position, the second position detecting member is used to detect whether the position limiting member 120 is in the second position, and the third position detecting member is used to detect whether the position limiting member 120 is in the third position. Optionally, the first position detecting member, the second position detecting member, and the third position detecting member are position sensors.
[0125] In this way, by detecting the position of the limiting member 120 , it is convenient to control the opening of the adsorption hole k and the subsequent cutting process or bonding process.
[0126] In some embodiments, please refer to Figures 10 to 13 The limiting member 120 has a limiting surface w configured to limit the edge of the curved object t in both the first direction F1 and the second direction F2. Optionally, a corresponding slot can be provided on the limiting member 120, with the slot walls forming the limiting surface w. By limiting the edge of the curved object t, the horizontal position accuracy of the curved object t during loading can be further improved.
[0127] It is understood that during the cutting process of the curved object t, since the edge of the curved object t needs to be cut, the supporting surface 110a is supported on the non-edge portion of the curved object t. When the curved object t is a round 3D spherical glass, the edge of the curved object t is located above the supporting surface 110a. That is, when the stopper 120 is in the first position and the second position, the limiting surface w is also located above the supporting surface 110a.
[0128] In some embodiments, please refer to Figures 10 to 13The material transfer device 100 further includes a limit driver 130 configured to drive the limit member 120 to reciprocate in the first direction F1. Optionally, the limit driver 130 may be a pressure cylinder. This facilitates the slow descent of the curved object t until it contacts the supporting surface 110a, thereby increasing the levelness of the curved object t in the first direction F1.
[0129] In some embodiments, please refer to Figures 10 to 12 The material transfer device 100 further includes a loading member 140. The loading member 140 is used to transfer the curved surface object t to the carrying surface 110a of the carrier 110. Thus, the curved surface object t can be placed on the carrying surface 110a by the cooperation between the loading member 140 and the limiting member 120.
[0130] In some embodiments, the material transfer device 100 further includes a pressure detection member (not shown) connected to the loading member 140. The loading member 140 is capable of adjusting the pressure applied to the curved object t in response to a detection signal from the pressure detection member. Optionally, the pressure detection member may be a pressure sensor. The provision of the pressure detection member facilitates detection of the downward pressure of the loading member 140 during loading, and the movement of the loading member 140 is controlled based on the detection signal from the pressure detection member.
[0131] In some embodiments, the loading member 140 is configured as a loading suction cup, and the loading member 140 can support the curved surface object t by means of suction force, thereby reducing damage to the curved surface object t.
[0132] In some embodiments, the material transfer device 100 further includes a material removal unit (not shown) for removing the curved object t from the support surface 110a of the carrier 110. This facilitates the material removal process by using the material removal unit. When the material transfer device 100 includes both the material removal unit 140 and the material removal unit, continuous processing and other processes can be achieved.
[0133] In some embodiments, the blanking member is configured as a blanking suction cup, which can support the curved object t on the supporting surface 110a by means of suction force, thereby reducing damage to the curved object t.
[0134] Based on the same inventive concept, the present embodiment also provides a loading method using the carrier 110 described in any of the above embodiments. This loading method can be used not only in the cutting process of curved surface objects t, but also in processes requiring fixed positions, such as the lamination and assembly process of curved surface objects t. The method can be selected based on the specific application, and the present embodiment does not impose any specific limitations on this.
[0135] Figure 14 A flow chart of a loading method in one embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0136] In some embodiments, please refer to Figure 14 , combined with reference Figures 8 to 13 The feeding method provided in the embodiment of the present application includes the following steps:
[0137] S110. Provide a carrier 110. The carrier 110 includes a body 111 and a plurality of elastic members 112. The body 111 has a plurality of receiving holes extending along a first direction F1. Each elastic member 112 is filled in a receiving hole. The body 111 and all the elastic members 112 form a supporting surface 110a along one side of the first direction F1. The carrier 110 has adsorption holes k extending along the first direction F1 and extending through the supporting surface 110a.
[0138] Specifically, since the carrier 110 has been described in any of the above embodiments, it will not be repeated here.
[0139] S120 , supporting the curved object t with the support surface 110 a , and fixing the curved object t by adsorption with the adsorption holes k.
[0140] Specifically, after placing the curved object t on the support surface 110a, the vacuum adsorption process is initiated, securing the curved object t via the adsorption holes k. Using this carrier 110 to secure the curved object t not only provides rigid support for the curved object t but also further enhances sealing and friction, improving the stability of the carrier 110 in securing the curved object t. This, in turn, reduces the risk of damage and deformation to the curved object t, enhances the appearance quality and optical performance of the curved object t, and facilitates subsequent processing of the curved object t.
[0141] In some embodiments, when the loading method is applied to a cutting process for a curved object t, the curved object t is supported by the supporting surface 110a and fixed by suction via the suction holes k. The method then includes cutting the curved object t through a cutting process. After cutting is completed, the carrier 110 is controlled to release the cut curved object t, and the cut curved object t is removed from the supporting surface 110a using a blanking member.
[0142] Figure 15 A flow chart of a loading method in another embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0143] In some embodiments, please refer to Figure 15 , combined with reference Figures 8 to 13 The feeding method provided in the embodiment of the present application includes the following steps:
[0144] S210. Provide a carrier 110. The carrier 110 includes a body 111 and a plurality of elastic members 112. The body 111 has a plurality of receiving holes extending along a first direction F1. Each elastic member 112 is filled in a receiving hole. The body 111 and all the elastic members 112 form a supporting surface 110a along one side of the first direction F1. The carrier 110 has adsorption holes k extending along the first direction F1 and extending through the supporting surface 110a.
[0145] For details, please refer to the contents of some of the aforementioned embodiments, which will not be repeated here.
[0146] S220, placing the curved object t on the carrying surface 110a with the aid of the loading member 140 and the limiting member 120; wherein the limiting member 120 is configured to limit the curved object t in a first direction F1 and a second direction F2; the first direction F1 and the second direction F2 are perpendicular to each other;
[0147] Specifically, by providing the limiting member 120 , the curved object t can be positioned, thereby improving the horizontal position accuracy of the curved object t.
[0148] S230 , supporting the curved object t with the support surface 110 a , and fixing the curved object t by adsorption with the adsorption holes k.
[0149] For details, please refer to the contents of some of the aforementioned embodiments, which will not be repeated here.
[0150] Figure 16 A flow chart of step S220 in an embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0151] In some embodiments, the limiting member 120 is configured to be able to reciprocate in the first direction F1, and the limiting member 120 has a first position and a second position during the movement; Figure 16 As shown, combined with reference Figures 10 to 13 , step S220 specifically includes:
[0152] S221, using the loading member 140 to carry the curved surface object t;
[0153] Specifically, the loading member 140 can be configured as a loading suction cup, which can support the curved object t by means of suction force. This can reduce damage to the curved object t. When the loading member 140 releases the curved object t in a subsequent step, the stability of the release process can also be further improved.
[0154] S222, using the loading member 140 to move the curved object t onto the limiting member 120 at the first position, so that a gap is formed between the curved object t and the carrying surface 110a;
[0155] Specifically, if Figure 11 As shown, the limiting member 120 in the first position can cooperate with the loading member 140, and the position of the curved object t can be adjusted before the curved object t is placed on the supporting surface 110a, thereby improving the accuracy of the loading position.
[0156] S223, using the loading member 140 and the limiting member 120 to jointly drive the curved object t to be placed on the carrying surface 110a; wherein, the limiting member 120 is in the second position, and the limiting member 120 and the carrying surface 110a jointly support the curved object t.
[0157] Specifically, if Figure 12 As shown, as the loading member 140 and the stopper 120 cooperate to drive the curved object t downward, the loading member 140 can continue to press the curved object t downward until the curved object t is completely in contact with the supporting surface 110a. This can improve loading accuracy while allowing the curved object t to better fit the supporting surface 110a.
[0158] In some embodiments, when loading with the aid of the loading member 140, the pressure applied by the loading member 140 to the curved object t can be controlled according to the detection signal of the pressure detection member; wherein the pressure detection member is connected to the loading member 140. The loading member 140 can adjust the pressure applied to the curved object t in response to the detection signal of the pressure detection member. Optionally, the pressure detection member can be a pressure sensor. Since the pressure detection member is provided, it is convenient to detect the downward pressure of the loading member 140 during loading, and to control the movement of the loading member 140 according to the detection signal of the pressure detection member. In this way, it is more conducive to controlling the loading process of the curved object t.
[0159] In some embodiments, as Figure 13 As shown, the limiting member 120 also has a third position during movement. After the curved object t is placed on the support surface 110a, the limiting member 120 is controlled to be in the third position so that the limiting member 120 is located below the support surface 110a on the plane, and the limiting member 120 is separated from the curved object t. Thus, through the three positions of the limiting member 120, the horizontal position of the curved object t can be first limited by the limiting member 120, and then the curved object t can be supported by the limiting member 120 and the support surface 110a. After the carrier 110 absorbs and fixes the curved object t, the limiting member 120 is retracted to the third position to avoid subsequent cutting or bonding processes.
[0160] In some embodiments, in conjunction with reference Figure 10 and Figure 13Before placing the curved object t on the supporting surface 110a using the loading member 140 and the stopper 120, the method further includes machining the stopper 120 through a processing technique so that the stopper 120 can engage with the edge of the curved object t. This reduces the relative coordinate error between the machine platform and the stopper 120, thereby reducing the relative error of the tool relative to the stopper 120 during the cutting process, improving the contour machining accuracy of the curved object t, and reducing the relative error between the bonding part and the curved object t during the bonding process, thereby improving the optical performance of the curved object t.
[0161] In some embodiments, in conjunction with reference Figure 10 and Figure 13 The curved object t has a contact surface t1 that contacts the supporting surface 110a. Before supporting the curved object t on the supporting surface 110a and securing the curved object t by suction via the suction holes k, the method further includes: processing the carrier 110 through a processing technique to adapt the shape of the supporting surface 110a to the shape of the contact surface t1. This reduces the relative coordinate error between the machine platform and the supporting surface 110a, thereby reducing the relative error of the tool relative to the carrier 110 during the cutting process, improving the contour processing accuracy of the curved object t, and reducing the relative error between the bonded component and the curved object t during the bonding process, thereby improving the optical performance of the curved object t.
[0162] It should be noted that some of the technical solutions described above can be implemented as independent embodiments in the actual implementation process, or they can be combined with each other and implemented as combined embodiments. In addition, when describing the contents of the above-mentioned embodiments of the present application, different embodiments are described in the corresponding order based on the idea of convenient description, such as the order preset according to the requirements in the actual implementation process, rather than limiting the execution order between different embodiments. Accordingly, in the actual implementation process, if it is necessary to implement multiple embodiments provided in the embodiments of the present application, it is not necessarily necessary to follow the execution order provided when the embodiments are described in the present invention, but the execution order between different embodiments can be arranged according to the needs.

[0164] Figure 17 A schematic diagram of the cutting deviation test results of a curved lens in one embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.
[0165] In combination with the contents of some of the above embodiments, taking the curved surface object t as a curved lens, and the curved lens being a round 3D spherical lens, the cutting process of the curved surface object t is taken as an example, the carrier 110, the limiter 120 and the loading member 140 shown in some of the above embodiments are used, and the limiter 120 and the loading member 140 cooperate with each other to load the curved surface object t, and CNC is used for cutting to obtain the following Figure 17 The test results are shown in the figure. Using a coordinate measuring machine, we can obtain the third contour line L3 and the fourth contour line L4. The third contour line L3 is the standard contour line, and the fourth contour line L4 is the actual cutting contour line. It can be seen that the third contour line L3 and the fourth contour line L4 basically overlap, showing a higher consistency.
[0166] In summary, in the carrier 110, the material transfer device 100 and the loading method provided by the embodiment of the present application, by using a body 111 with a receiving hole, the elastic member 112 is filled in the receiving hole, and the curved object t is fixed by adsorption with the help of the adsorption hole k, which not only satisfies the rigid support of the carrier 110, but also improves the sealing and friction, thereby improving the situation where the curved object t is damaged and deformed, and improving the appearance quality and optical performance of the curved object t. At the same time, the adsorption holes k can be opened more evenly on the carrier 110 to more evenly distribute the vacuum adsorption force, reducing the microscopic changes caused to the curved object t by uneven adsorption force. In the material transfer device 100, by setting the loading member 140 and the limiting member 120 to cooperate with the carrier 110, the position accuracy of the curved object t is further improved. Furthermore, through the relevant detection parts and by driving the limiting member 120 with the help of a pressure cylinder, the process of placing the curved object t on the carrier 110 can be further made more stable, further improving the position accuracy of the curved object t. This process allows for more precise loading of curved objects t. Prior to loading, machining the stopper 120 and the support surface 110a can reduce the errors introduced by the stopper 120 and the support surface 110a themselves. In other words, improvements to the carrier 110, along with improvements to the loading process and pre-loading procedures, ultimately further improve the machining accuracy of the curved object t's contour or the accuracy of its fitting. This reduces the risk of damage and deformation to the curved object t, improving its appearance quality and optical performance.
