[0065] Figure 1 A schematic diagram of the structure of a curved surface component according to an embodiment of this application is shown. Figure 2 A schematic diagram of the fixing device in one embodiment of this application is shown. Figure 3 It shows Figure 2 A schematic diagram of the load-bearing component is shown. In the diagram, the first direction F1 and the second direction F2 are opposite.

[0066] Please see Figures 1 to 3 This application provides a fixing device 100 for fixing a curved component 10. The curved component 10 has a first curved surface 10a disposed along a first direction F1, and the first curved surface 10a is bent toward the first direction F1. The fixing device 100 includes a support member 110 and a positioning member 120. The support member 110 has a support surface 110a recessed along the first direction and an adsorption hole k penetrating the support surface 110a. The support surface 110a is used to support the curved component 10 by means of the first curved surface 10a. The positioning member 120 is configured to be movably disposed relative to the support member 110. The fixing device 100 has a positioning state and a fixing state. In the positioning state, the positioning member 120 engages with the curved component 10 to position the curved component 10. In the fixing state, the positioning member 120 is separated from the curved component 10, the support surface 110a is in contact with the first curved surface 10a, and the support surface 110a is fixed relative to the first curved surface 10a by means of the adsorption hole k.

[0067] The curved surface component 10 refers to a product with a curved surface. Specifically, in some embodiments, the curved surface component 10 can be, for example, a curved lens or curved eyeglasses. The curved surface component 10 has a first curved surface 10a disposed along a first direction F1, and simultaneously has a second curved surface (not shown in the figure) disposed along a second direction F2; that is, the first curved surface 10a and the second curved surface are two curved surfaces of the curved surface component 10 that are opposite to each other. The first curved surface 10a is curved towards the first direction F1, that is, the first curved surface 10a can be roughly considered as a convex surface, and the second curved surface can be roughly considered as a concave surface. It should be noted that the edge region of the first curved surface 10a, that is, the edge region of the curved surface component 10, is the processing area R. Furthermore, the curvature and thickness of the curved surface component 10 can be set according to actual conditions; this embodiment does not impose any limitations on this.

[0068] The support member 110 refers to the component used to support the curved component 10. The support member 110 has a support surface 110a recessed along the first direction F1, that is, the support surface 110a can be roughly regarded as a concave surface curved towards the first direction F1. It should be noted that the support surface 110a can be a continuous surface or a discontinuous surface. A portion of the surface of the first curved surface 10a can fit into a portion or all of the surface of the support surface 110a, thereby allowing the curved component 10 to be supported on the support member 110.

[0069] Furthermore, an adsorption hole k penetrating the bearing surface 110a is provided on the bearing member 110. This adsorption hole k refers to a structure that allows gas flow under negative pressure operation. The adsorption hole k can be a round hole, a rectangular hole, or other shaped hole, or it can be a slot, and can be set according to actual needs; this embodiment does not impose specific limitations on this. It should be noted that when a portion of the surface of the first curved surface 10a is in contact with a portion or all of the surface of the bearing surface 110a, the opening of the adsorption hole k can be in contact with the first curved surface 10a, or the opening of the adsorption hole k can be located below the first curved surface 10a, that is, the opening of the adsorption hole k can be located at the bottom or side of the bearing surface 110a, as long as it can reduce the air pressure between the first curved surface 10a and the bearing surface 110a under negative pressure operation, so that the first curved surface 10a can be held by the bearing surface 110a.

[0070] The positioning component 120 refers to a component used to position the circumferential orientation of the curved surface component 10 (i.e., the circumferential orientation of the outer contour of the first curved surface 10a). For example, positioning marks can be set on the first curved surface 10a, and the positioning component 120 can be aligned with the positioning marks. As long as the circumferential orientation of the curved surface component 10 can be positioned, this embodiment does not impose specific limitations. It should be noted that during the positioning process of the positioning component 120 on the curved surface component 10, the positioning component 120 will more or less obstruct the area to be processed of the curved surface component 10. By setting the positioning component 120 to be movable relative to the support component 110, after positioning is completed, the positioning component 120 can be moved away from the support component 110, that is, moved away from the area around the curved surface component 10, so that the area R to be processed of the curved surface component 10 can be fully exposed, facilitating subsequent tool processing. It should be noted that the positioning element 120 can be a detachable structure or a movable structure, as long as it can be removed from the support element 110 after positioning is completed. This embodiment does not impose specific limitations on this. In addition, there can be a transition state between the positioning state and the fixing state of the fixing device 100. That is, the positioning element 120 can be removed from the support element 110 after the negative pressure operation is completed (completely fixing the curved part 10 to the support element 110).

[0071] Specifically, during the process of placing the curved part 120 on the carrier 110, the curved part 10 is first positioned by the positioning member 120, and part of the surface of the first curved surface 10a can be in contact with part or all of the surface of the carrier surface 110a. After the positioning member 120 has positioned the curved part 10, the positioning member 120 can be moved away from the curved part 10. Then, a negative pressure operation can be performed by using the suction hole k to hold the first curved surface 10a on the carrier surface 110a. In this way, the curved part 10 is fixed to the carrier 110, reducing the movement of the curved part 10 during the processing, and allowing the edge area of ​​the curved part 10 (i.e., the area R to be processed) to be fully exposed, which is convenient for subsequent tool processing.

[0072] The fixing device 100 in this embodiment includes at least a support member 110 and a positioning member 120. By providing a support surface 110a that is recessed along a first direction, the support surface 110a can support the curved part 10 with the help of the first curved surface 10a. By providing an adsorption hole k that penetrates the support surface 110a, the support surface 110a can be fixed relative to the first curved surface 10a with the help of the adsorption hole k. By providing a positioning member 120 that can move relative to the support member 110, after the positioning member 120 has completed positioning the curved part 10, the positioning member 120 can move away from the curved part 10, so that the entire area R to be processed of the curved part 10 is exposed, achieving one-time positioning. Then, the first curved surface 10a is fixed to the support surface 110a, which facilitates the subsequent processing of the area R to be processed of the curved part 10 by the tool, so as to achieve one-time processing and improve the processing accuracy of the curved part 10.

[0073] Compared to related technologies where the carrier 110 and the positioning element 120 are integrated into a single structure, the positioning element 120 obstructs part of the machined area R of the curved surface part 10, requiring multiple positioning and machining operations to complete the machining of the entire machined area R. However, during these multiple positioning operations, the positioning position is prone to deviation, causing the tool to deviate from the alignment reference position of the curved surface part 10. In this embodiment, by setting the positioning element 120 to be movable relative to the carrier 110, after the positioning element 120 has completed positioning of the carrier 110, it can be moved away from the periphery of the curved surface part 10, so that the machined area R of the curved surface part 10 can be fully exposed, facilitating subsequent tool machining. This achieves a one-time positioning and machining process, improving the machining accuracy of the curved surface part 10.

[0074] Figure 4 A projection diagram of a curved surface component supported on a carrier component is shown in one embodiment of this application.

[0075] See Figure 4In some embodiments, the orthographic projection of the bearing surface 110a onto the reference plane (i.e., the first projection s1) lies within the orthographic projection of the curved component 10 onto the reference plane (i.e., the second projection s2). The reference plane is a plane perpendicular to the first direction F1. It should be noted that the outer contour shape of the orthographic projection of the bearing surface 110a onto the reference plane can be circular, elliptical, or other closed shapes with curves, or it can be rectangular or other closed shapes without curves. The outer contour shape of the orthographic projection of the curved component 10 onto the reference plane can be circular, elliptical, or other closed shapes with curves.

[0076] Specifically, the orthographic projection of the bearing surface 110a onto the reference surface lies within the orthographic projection of the curved part 10 onto the reference surface, and the outer contour of the orthographic projection of the curved part 10 onto the reference surface lies outside the outer contour of the orthographic projection of the bearing surface 110a onto the reference surface. That is, a portion of the surface of the first curved surface 10a is in contact with a portion or all of the surface of the bearing surface 110a. A gap exists between the outer contour of the first curved surface 10a and the outer contour of the bearing surface 110a along the first direction F1, allowing the edge region of the first curved surface 10a (i.e., the edge region of the curved part 10) to be exposed. This facilitates subsequent machining of the entire edge region of the curved part 10 by the subsequent cutting tool, contributing to a one-time machining process.

[0077] In other embodiments, the orthographic projection of the bearing surface 110a onto the reference surface coincides with the orthographic projection of the curved component 10 onto the reference surface. Alternatively, the orthographic projection of the bearing surface 110a onto the reference surface may be located outside the orthographic projection of the curved component 10 onto the reference surface. Specifically, the curvature of the bearing surface 110a can be adjusted, or the bearing surface 110a can be configured as a surface with different curvatures, as long as there is a gap along the first direction F1 between the outer contour of the first curved surface 10a and the outer contour of the bearing surface 110a to facilitate subsequent processing. This embodiment does not impose specific limitations on this.

[0078] Continue reading Figure 2 and Figure 3 In some embodiments, the positioning element 120 is arranged around the outer contour (i.e., the first outer contour w1) of the bearing surface 110a. For example, a positioning mark can be set on the first curved surface 10a, and the positioning element 120 can be aligned with the positioning mark. As long as the circumferential orientation of the curved surface element 10 can be positioned, this embodiment does not impose any specific limitations.

[0079] In this way, the circumferential orientation of the curved part 10 can be adjusted according to the positioning part 120 located around the outer contour of the bearing surface 110a, so as to position the circumferential orientation of the curved part 10, which helps to improve the machining accuracy of the curved part 10, and also makes it easier for the tool to keep the alignment reference position of each subsequent curved part 10 basically unchanged, thereby improving the positioning machining efficiency.

[0080] See Figure 5 and Figure 6 , Figure 5 It shows Figure 2 A schematic diagram of the limiting component in the middle. Figure 6 It shows Figure 2 This is a schematic diagram of the use of a fixing device. In some embodiments, the positioning member 120 includes a positioning portion 121, which is disposed around the outer contour of the bearing surface 110a. Along the circumferential direction of the outer contour of the bearing surface 110a, the positioning portion 121 is provided with a limiting space Q. The limiting space Q is used to accommodate at least a portion of the curved surface member 10 to limit the curved surface member 10. Further, the curved surface member 10 is provided with a protrusion p, which is located on the first curved surface 10a. Along the circumferential direction of the first curved surface 10a, the limiting space Q is used to limit the protrusion p.

[0081] It should be noted that the positioning part 121 can refer to a component used for positioning the circumferential orientation of the curved surface part 10. The positioning part 121 can be a single integral component or composed of multiple sub-components. Along the circumferential direction of the outer contour of the bearing surface 110a, the positioning part 121 is provided with one or more grooves, and the space within the groove is also known as the limiting space Q.

[0082] For example, the curved component 10 can be a curved lens, and the convex surface (i.e., the first curved surface 10a) of the curved lens has a protrusion p. The protrusion p can refer to a structure that facilitates the positioning of the curved lens, or it can refer to a structure that facilitates the mounting of the curved lens to the product housing. The protrusion p is placed in a limiting space Q, which can cooperate with the protrusion p. In this way, in the positioning state, the protrusion p is limited by the limiting space Q, thereby positioning the curved component 10 in its circumferential direction, which not only helps to improve the positioning accuracy of the curved component 10, but also facilitates operation.

[0083] Continue reading Figure 5 and Figure 6 In some embodiments, the positioning part 121 includes a plurality of sub-positioning parts 121a. The plurality of sub-positioning parts 121a are spaced apart around the outer contour of the bearing surface 110a. Specifically, a sub-positioning part 121a refers to a sub-component used for positioning the circumferential orientation of the curved surface member 10. The plurality of sub-positioning parts 121a are spaced apart around the outer contour of the bearing surface 110a, thus defining a limiting space Q between adjacent sub-positioning parts 121a. Further, the curved surface member 10 has a protrusion p located on the first curved surface 10a. Along the circumferential direction of the first curved surface 10a, the limiting space Q limits the protrusion p.

[0084] For example, the curved component 10 can be a curved lens, and the convex surface of the curved lens (i.e., the first curved surface 10a) has three protrusions p. Three sub-positioning parts 121a can be provided to define three limiting spaces Q. The three protrusions p can be inserted into the three limiting spaces Q, or the spacing between two adjacent sub-positioning parts 121a can be set according to the actual situation, so that the three protrusions p are placed in the corresponding three limiting spaces Q in the positioning state. Among the two sidewalls of the protrusions p arranged opposite each other along the outer contour circumferential direction of the bearing surface 110a, at least one sidewall blocks the sidewall of a nearby sub-positioning part 121a to limit the protrusion p in the clockwise or counterclockwise direction. Thus, by reasonably setting the positions of the three sub-positioning parts 121a, the curved component 10 can be positioned in its circumferential direction, which not only helps to improve the positioning accuracy of the curved component 10, but also facilitates operation.

[0085] Continue reading Figure 5 In some embodiments, the sub-positioning part 121a is provided with a clearance area r. This clearance area r refers to the region where at least another portion of the protrusion p of the curved member 10 is avoided when at least a portion of the protrusion p is placed in the limiting space Q. For example, the protrusion p can be constructed as a structure generally resembling a step. A portion of the protrusion p can be placed in the limiting space Q, and another portion of the protrusion p can be placed in the clearance area r of the sub-positioning part 121a. This reduces positioning deviation and improves the positioning accuracy of the positioning member 120 for the curved member 10.

[0086] In some embodiments, in the positioning state, the positioning member 120 contacts the first curved surface 10a. Further, the positioning portion 121 is configured to make line contact with the first curved surface 10a. Specifically, the side of the positioning portion 121 near the bearing surface 110a can be constructed as a curved side structure. Thus, while a portion of the surface of the first curved surface 10a is in contact with the bearing surface 110a, another portion of the first curved surface 10a can make line contact with the positioning portion 121, improving positioning accuracy.

[0087] Alternatively, the positioning part 121 can be configured to contact the surface of the first curved surface 10a. Specifically, the side of the positioning part 121 near the bearing surface 110a can be constructed as a curved side structure. In this way, when a portion of the surface of the first curved surface 10a is in contact with the bearing surface 110a, another portion of the first curved surface 10a can contact the surface of the positioning part 121, thereby improving positioning accuracy.

[0088] Continue reading Figure 2 , Figure 3 and Figure 5In some embodiments, the positioning member 120 further includes a fixing portion 122, which has a positioning portion 121. The fixing portion 122 is sleeved on the support member 110. For example, at least a portion of the support member 110 can be constructed as a cylindrical structure, and the at least portion of the support member 110 has a bearing surface 110a. The fixing portion 122 has a through hole, which allows the fixing portion 122 to be sleeved on the at least portion of the support member 110, and the positioning portion 121 to be disposed around the outer contour of the bearing surface 110a.

[0089] Figure 6 It shows Figure 2 A schematic diagram of the use of the fixing device in the middle. Figure 7 It shows Figure 2 A schematic diagram illustrating another usage process of the fixing device. (See attached diagram.) Figure 6 and Figure 7 In some embodiments, the positioning member 120 is configured to reciprocate along a first direction F1. Specifically, the fixing part 122 can be configured to move along the first direction F1, so that the positioning member 120 can move along the first direction F1. Thus, after the positioning member 120 is positioned, its position is lowered, facilitating the machining of the entire machined area R of the curved surface part 10 by the cutting tool. Simultaneously, the fixing part 122 can be configured to move along a second direction F2, so that the positioning member 120 can move along the second direction F2. Thus, when different positioning members 120 are used for different curved surface parts 10, the height of the positioning member 120 can be easily adjusted to improve the positioning accuracy of the curved surface part 10.

Figure 8(b) shows a schematic diagram of the structure of another clamp consisting of a carrier and a positioning element in a pair of proportions of this application.

[0091] See Figures 8(a), 8(b) and Figure 9The positioning member 120 is fixed to the carrier member 110 to form a fixture 200 with an integral structure. The fixture 200 uses the carrier member 110 to support the curved part 10 and uses the positioning member 120 to limit the protrusion p of the curved part 10. However, during the clamping of the curved part 10, the positioning part 121 of the positioning member 120 limits the limiting part A1 of the curved part 10. The limiting part A1 is part of the area to be processed R. Therefore, using a fixture 200 to clamp the curved part 10 will result in a part of the area to be processed R not being processed. As shown in Figure 8(b), another fixture 300 needs to be made. The spacing of the positioning part 121 of fixture 300 is different from that of the positioning part 121 of fixture 200. The positioning part 121 of fixture 300 limits the limiting part A2 of curved part 10, so that the limiting part A1 can be processed to complete the processing of the entire processing area R of curved part 10. However, in this process, the two clamping and positioning positions are prone to deviation, which will also cause the tool to deviate from the alignment and processing reference position of curved part 10, thus affecting the overall processing accuracy of the product.

[0092] Compared to the above-mentioned integrated structure of positioning member 120 and bearing member 110, this embodiment of the application sets the height of positioning member 120 to be adjustable. After positioning member 120 is completed, its position can be lowered, which facilitates the tool to process all the areas R to be processed of curved surface part 10. In this way, the processing can be completed in one go, reducing the need for secondary clamping. At the same time, the tool's alignment reference position for each subsequent curved surface part 10 remains basically unchanged, improving the positioning processing efficiency.

[0093] Continue reading Figure 2 and Figure 6 In some embodiments, the positioning member 120 is configured to reciprocate along a first direction F1. Specifically, the positioning member 120 can move along either the first direction F1 or the second direction F2. After the positioning member 120 has positioned the curved part 10, it can be moved along the first direction F1 so that the entire area to be machined on the curved part 10 can be exposed for easy tooling. Then, before the next curved part 10 is placed on the support member 110, the positioning member 120 can be moved along the second direction F2 to a preset position so that it can position the curved part 10.

[0094] Continue reading Figure 2 and Figure 6 and combined Figure 10 In some embodiments, the fixing device 100 further includes a drive mechanism 130. The drive mechanism 130 is configured to drive the positioning member 120 to reciprocate along a first direction F1.

[0095] Specifically, the drive mechanism 130 may include two drive components 131 and a platform 132. The platform 132 has two oppositely arranged sides, each connected to a drive component 131. Each drive component 131 may include a guide 131a and a drive component 131b. The guide 131a may be a linear guide rail. The drive component 131b may be a lifting cylinder or a linear motor. The guide 131a is connected to the platform 132. The drive component 131b drives the guide 131a to reciprocate along a first direction F1, that is, the drive component 131b drives the guide 131a to move along the first direction F1 or a second direction F2. The two drive components 131b on both sides of the platform 132 can synchronously drive the corresponding guide 131a to realize the reciprocating movement of the platform 132 along the first direction F1. Further, the bearing 110 and the positioning 120 may both pass through the platform 132, and the positioning 120 is detachably installed on the platform 132. Thus, when the stage 132 reciprocates along the first direction F1, the positioning member 120 can also reciprocate along the first direction F1.

[0096] Furthermore, the fixing device 100 also includes a limiting member 140. The limiting member 140 is configured to limit the positioning member 120 during its movement along the second direction F2.

[0097] Specifically, the limiting member 140 refers to a component that limits the movement displacement of the positioning member 120. In the case where the drive mechanism 130 includes two drive components 131 and a platform 132, limiting members 140 are provided on both sides of the platform 132. Thus, during the movement of the platform 132 along the second direction F2, the platform 132 is limited; that is, during the movement of the positioning member 120 along the second direction F2, the positioning member 120 is limited, causing it to move to a preset position along the second direction F2, thereby enabling the positioning member 120 to perform the function of positioning the curved surface member 10.

[0098] Continue reading Figure 6 Furthermore, the drive mechanism 130 also includes a buffer 133, which is located on the side of the platform 132 opposite to the positioning member 120. During the movement of the platform 132 along the first direction F1, the contact between the platform 132 and the buffer 133 can determine the descent position of the platform 132 and also serve as a buffer.

[0099] Referring again to 3, in some embodiments, the fixing device 100 further includes a seal 150. The seal 150 is sealably connected between the first curved surface 10a and the bearing surface 110a. Further, the orthographic projection of the seal 150 onto the reference surface is outside the orthographic projection of the adsorption hole k onto the reference surface. The reference surface is a plane perpendicular to the first direction F1.

[0100] Specifically, the seal 150 can be made of a flexible material such as rubber. The seal 150 can be configured as a ring structure. The seal 150 can be mounted on the bearing surface 110a, with the first curved surface 10a of the curved member 10 contacting the seal 150, and the seal 150 and the first curved surface 10a in contact along the circumferential direction of the seal 150. Furthermore, the orthographic projection of the seal 150 on the reference surface is outside the orthographic projection of the adsorption hole k on the reference surface, that is, the adsorption hole k is located on the side of the bearing surface 110a away from the first curved surface 10a along the first direction F1. Thus, the first curved surface 10a and the bearing surface 110a are sealed together by the sealing element 150, and under the negative pressure operation by means of the adsorption hole k, the first curved surface 10a and the bearing surface 110a can be attracted to each other, improving the sealing effect between the first curved surface 10a and the bearing surface 110a. In addition, the flexible material sealing element 150 can play a certain protective role for the curved surface part 10 and reduce the risk of the curved surface part 10 breaking.

[0101] In some embodiments, the fixing device 100 further includes an air extraction component configured to extract air via an adsorption hole k. The inlet of the air extraction component and the adsorption hole k can be connected by a pipe, so that after the first curved surface 10a and the bearing surface 110a are in contact, the air extraction component performs a negative pressure operation via the adsorption hole k, causing the first curved surface 10a and the bearing surface 110a to be held together, thereby fixing the curved surface 10 to the bearing surface 110.

[0102] Referring further to section 2, the fixing device 100 also includes a control element 160. The control element 160 is configured to control the switching of the suction component. And / or, the control element 160 is configured to control the switching of the drive mechanism 130. Specifically, the control element 160 is electrically connected to the suction component and the drive mechanism 130. This facilitates control of the negative pressure operation of the suction component and / or the lifting operation of the drive mechanism.

[0103] According to the same inventive concept, embodiments of this application also provide a processing apparatus, including a fixing device 100 as described in any previous embodiment. The processing apparatus may further include a cutting tool. The cutting tool is used to process the processing area R of the curved surface part 10.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
