[0053] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0054] The following is for reference. Figures 1-5 The positioning fixture 100 provided in the embodiments of this application is described. The positioning fixture 100 includes an installation platform 110, a plurality of support members 120 and a limiting member 130.

[0055] It should be noted that the size and shape of the installation platform 110 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0056] Multiple support members 120 are circumferentially spaced apart. Each support member 120 protrudes from the top surface of the mounting platform 110 and forms a positioning part, which is used for positioning and engaging with the body 910 of the component to be tested. A limiting member 130 protrudes from the top surface of the mounting platform 110 and is used for limiting and engaging with the cable 920 of the component to be tested. The connection methods between the support members 120 and the mounting platform 110, as well as between the limiting member 130 and the mounting platform 110, include, but are not limited to, threaded connections, snap-fit ​​connections, or welding.

[0057] It should be noted that the items to be tested include, but are not limited to, wearable devices such as VR glasses.

[0058] Understandably, multiple support members 120 are circumferentially distributed to provide uniform support for the part to be tested. Simultaneously, the support members 120 protrude from the top surface of the mounting platform 110, enabling support of the part to be tested while avoiding obstruction of its temples. Furthermore, the support members 120 form a positioning part that matches the body 910 of the part to be tested, ensuring accurate positioning of the part on the mounting platform 110 and facilitating subsequent testing. The limiting member 130, located on the mounting platform 110, secures the cable 920 of the part to be tested, reducing displacement of the cable 920 during subsequent testing and ensuring testing efficiency and reliability.

[0059] The positioning fixture 100 provided in the embodiments of this application improves the efficiency and reliability of testing by accurately positioning the workpiece to be tested.

[0060] In some embodiments, such as Figure 2 and Figure 3As shown, the support member 120 includes a main body segment 121, a first abutting segment 122, and a second abutting segment 123. The lower end of the main body segment 121 is disposed on the mounting platform 110. The first abutting segment 122 protrudes from the upper end surface of the main body segment 121. The second abutting segment 123 protrudes from the upper end surface of the main body segment 121 and is connected to the first surface 1221 of the first abutting segment 122, and the top surface of the second abutting segment 123 is lower than the top surface of the first abutting segment 122. The positioning part includes the top surfaces of the first surface 1221 and the second abutting segment 123. Exemplarily, the shape of the main body segment 121 includes, but is not limited to, an L-shape.

[0061] Understandably, the main body segment 121 extends vertically and is mounted on the mounting platform 110 to provide support; the first abutment segment 122 and the second abutment segment 123 are both located on the top surface of the main body segment 121 and connected to each other, and the top surface of the first abutment segment 122 is higher than the top surface of the second abutment segment 123 to form a step, so that the main body 910 can simultaneously abut against the top surfaces of the first surface 1221 and the second abutment segment 123, increasing the contact area while improving the accuracy and stability of positioning.

[0062] In some embodiments, such as Figure 3 As shown, the first surface 1221 of the first abutting section 122 faces the center of the mounting platform 110 along the first horizontal direction, and at least a portion of the first surface 1221 of the support member 120 is an arc surface that protrudes away from the mounting platform 110. It should be noted that the size and radius of curvature of the arc surface can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0063] Understandably, the second abutment section 123 is connected to the first surface 1221, meaning the second abutment section 123 is closer to the center of the mounting platform 110 than the first abutment section 122. The first surface 1221 is an arc surface with its center of curvature close to the center of the mounting platform 110, which can reduce stress concentration, increase the contact area with the outer wall of the part to be tested, reduce the risk of damage to the part to be tested during positioning, and help the part to be tested move smoothly during the picking process.

[0064] In this embodiment, as Figure 3 As shown, the first surface 1221 of the support member 120 located at the corner of the mounting platform 110 is an arc surface, while the first surface 1221 of the support member 120 near the middle of the edge of the mounting platform 110 is a flat surface.

[0065] In some embodiments, such as Figure 3 As shown, along the second horizontal direction, the side surface of the second abutment segment 123 and the side surface of the first abutment segment 122 together form a continuous plane.

[0066] It should be noted that the first horizontal direction and the second horizontal direction intersect. In this embodiment, when the part to be tested is placed on the positioning fixture 100, the first horizontal direction refers to the width direction of the body 910, and the second horizontal direction refers to the length direction of the body 910.

[0067] It is understandable that, since the first surface 1221 is located on the side of the first abutting section 122 arranged along the first horizontal direction, and the second abutting section 123 is connected to the first surface 1221, by making the two sides of the second abutting section 123 arranged opposite to each other along the second horizontal direction and the two sides of the first abutting section 122 corresponding to each other form a continuous plane, it helps to improve the support and play the role of dispersing stress and avoiding the test piece.

[0068] In some embodiments, such as Figure 2 As shown, the support member 120 also includes a buffer member 124, which covers the outer walls of the first abutment section 122 and the second abutment section 123, and the outer wall of the buffer member 124 and the outer wall of the main body section 121 together form a continuous plane. The material of the buffer member 124 includes, but is not limited to, rubber or silicone.

[0069] It is understood that the buffer 124 covers the outer walls of the first abutment section 122 and the second abutment section 123. That is, the body 910 of the component to be tested abuts against the first abutment section 122 and the second abutment section 123 respectively through the buffer 124, to provide additional protection and cushioning, reduce the possibility of surface damage to the component to be tested, and increase friction, thereby reducing the possibility of displacement of the component to be tested during the testing process, which helps to ensure the stability and positioning accuracy of the component to be tested. At the same time, the outer wall of the buffer 124 and the outer wall of the main body section 121 together form a continuous plane, reducing stress concentration points and structural weaknesses, and improving the durability, reliability and aesthetics of the support 120.

[0070] In some embodiments, such as Figures 1 to 5 As shown, the positioning fixture 100 includes multiple support members 120. A portion of the support members 120 is located at the corner of the mounting platform 110, and another portion of the support members 120 is located at the center of the edge of the mounting platform 110. It should be noted that the number and specific distribution of the support members 120 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0071] Understandably, the support member 120 located at the corner can accurately position the corner of the body 910, and the support member 120 located in the middle of the edge may be used to support the middle edge of the body 910, ensuring that the entire test piece is subjected to uniform force while avoiding the lens of the body 910, so as to improve the reliability of subsequent testing.

[0072] In this embodiment, as Figures 1 to 5 As shown, there are five support members 120, four of which are located at the four corners of the mounting platform 110, and the other support member 120 is located between two support members 120 spaced apart along the second horizontal direction.

[0073] In some embodiments, the top surface of the support member 120 located at the corner of the mounting platform 110 is a flat surface, and the top surface of the support member 120 located at the middle of the edge of the mounting platform 110 is an upwardly convex arc surface. It should be noted that the size and shape of the flat surface and the arc surface can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0074] Understandably, the flat top surface of the support member 120 provides solid support at the corners, which helps to maintain the stability of the part under test; the curved top surface of the support member 120 provides better adaptability at the middle of the edge, which can match the curvature shape of the part under test, increase the contact area with the part under test, and improve the overall support effect.

[0075] In some embodiments, such as Figures 1 to 5 As shown, a limiting member 130 is provided between at least two adjacent support members 120, and the limiting member 130 is provided with a through groove 131 along the first horizontal direction, and the opening of the through groove 131 faces downward.

[0076] Understandably, the limiting member 130 has a through groove 131 extending along the first horizontal direction, thereby allowing the ribbon cable 920 to pass through the through groove 131 along the first horizontal direction to accommodate ribbon cables 920 of different lengths. At the same time, the opening of the through groove 131 faces downward, which not only facilitates the entry and exit of the ribbon cable 920 into the through groove 131 and limits the ribbon cable 920 in the vertical direction, but also reduces the possibility of dust and other impurities remaining in the through groove 131.

[0077] In this embodiment, as Figures 1 to 5 As shown, there are two limiting members 130, and the two limiting members 130 and three support members 120 spaced apart along the second horizontal direction are staggered.

[0078] In some embodiments, such as Figures 1 to 5 As shown, the height of the through slot 131 is adjustable, thus accommodating cabling 920 at different heights, improving adaptability, positioning efficiency, and accuracy. It should be noted that the specific shape and size of the through slot 131 can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0079] In some embodiments, such as Figures 1 to 3As shown, the positioning fixture 100 also includes an adjusting block 140 corresponding to the limiting member 130. The adjusting block 140 is disposed on the mounting platform 110. The lower part of the limiting member 130 and one of the adjusting blocks 140 are provided with a first connecting hole 132 in the shape of an elongated strip. The lower part of the limiting member 130 and the other of the adjusting blocks 140 are provided with a plurality of first mounting holes spaced apart in the vertical direction. That is, by cooperating with the first connecting hole 132 and different first mounting holes, the height of the limiting member 130 can be adjusted on the adjusting block 140, thereby realizing the height adjustment of the through groove 131.

[0080] In this embodiment, as Figure 1 As shown, the first connecting hole 132 is provided on the limiting member 130, and the first mounting hole is provided on the adjusting block 140.

[0081] This application also provides a detection device.

[0082] like Figure 4 As shown, the detection device includes a base 200, a rotation drive 300, an imaging structure, and the aforementioned positioning fixture 100. The fixed end of the rotation drive 300 is connected to the base 200. The positioning fixture 100 is used to carry the workpiece to be detected. The driving end of the rotation drive 300 is connected to the positioning fixture 100 and is used to drive the positioning fixture 100 to rotate in the up-down direction. The imaging structure is used to obtain image information of the body 910 of the workpiece to be detected. The imaging structure includes a prism assembly 400, which is disposed on the positioning fixture 100 and located below the body 910 of the workpiece to be detected. Exemplarily, the rotation drive 300 includes, but is not limited to, a rotary motor.

[0083] It should be noted that the camera and lens of the imaging component are both located above the main body 910. The camera above can capture a direct image of the lens surface from the vertical direction, while the prism 420 below can use the principle of reflection to enable the camera to capture the bottom of the lens or parts that are not directly visible, thus enhancing the comprehensiveness of the detection.

[0084] Understandably, after the workpiece to be inspected is fixed onto the positioning fixture 100, the rotation drive 300 drives the positioning fixture 100 to rotate, while simultaneously cooperating with the imaging structure to obtain a 360-degree image of the workpiece, thereby achieving comprehensive and reliable inspection of the workpiece. Meanwhile, the prism assembly 400 is positioned on the positioning fixture 100 and below the main body 910, which not only makes the overall structure of the inspection device more compact but also enables effective optical interaction with the workpiece to perform optical scanning or analysis, improving the accuracy and efficiency of the inspection.

[0085] The detection device provided in the embodiments of this application improves detection efficiency and reliability by performing comprehensive imaging of the test piece.

[0086] In some embodiments, such as Figure 5 As shown, the prism assembly 400 includes two mounting bases 410 and two prisms 420 arranged at an angle. The mounting bases 410 are disposed on the positioning fixture 100; the prisms 420 and the mounting bases 410 correspond to each other and are connected.

[0087] It is understandable that the mounting base 410 is set on the mounting platform 110, and by setting two prisms 420 at an included angle, the direction of light propagation is changed, so as to accurately control the path of light, expand the imaging range of the object to be inspected, and thus improve the inspection efficiency and reliability.

[0088] In this embodiment, as Figure 5 As shown, the mounting base 410 is located near the center of the mounting platform 110, and the two mounting bases 410 are distributed sequentially along the second horizontal direction.

[0089] In some embodiments, such as Figure 5 As shown, multiple support members 120 are arranged circumferentially around the mounting base 410, which ensures that the entire testing device has a compact structure while achieving uniform support for the test piece and comprehensive testing.

[0090] In some embodiments, such as Figure 5 As shown, the two prisms 420 are tilted downwards in a direction that keeps them apart from each other. It should be noted that the tilt angle of the prisms 420 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0091] Understandably, the two prisms 420 are tilted downwards in a direction that moves away from each other, meaning that the sides of the two prisms 420 closest to the body 910 form an obtuse angle with each other, thus creating an optical layout in which the light path diverges outwards. This allows the lens of the imaging component to cover a wider field of view, thereby expanding the detection area and improving the comprehensiveness and accuracy of the detection.

[0092] In some embodiments, such as Figure 5 As shown, the opposing sides of the two prisms 420 are curved surfaces, and the center of curvature of the curved surfaces is located inside the prisms 420. It should be noted that the radius of curvature of the curved surfaces can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0093] Understandably, the two prisms 420 have opposing sides that are curved surfaces that bulge in opposite directions. This allows for adjustment of the light's focal point, enabling more precise control of the light path and enhancing the imaging quality and detection capability at the edge of the body 910.

[0094] In some embodiments, such as Figure 5As shown, the installation angle of prism 420 is adjustable to precisely control the propagation direction of light, adapting to different sizes of test pieces and testing requirements, thus improving the flexibility and versatility of the testing device.

[0095] In some embodiments, such as Figure 5 As shown, the prism assembly 400 also includes two first mounting members 430 and two second mounting members 440. The two first mounting members 430, the two second mounting members 440 and the two prisms 420 correspond one-to-one. The first mounting member 430 is perpendicular to the side of the prism 420 away from the body 910 and is hinged to the second mounting member 440. The second mounting member 440 is connected to the mounting base 410. One of the first mounting member 430 and the second mounting member 440 is provided with an arc-shaped second connecting hole, and the other of the first mounting member 430 and the second mounting member 440 is provided with a second mounting hole. That is, the inner edges of the second mounting hole and the second connecting hole are matched at different points, so that the angle of the first mounting member 430 can be adjusted by being set on the second mounting member 440, thereby realizing the angle adjustment of the prism 420.

[0096] In some embodiments, such as Figure 5 As shown, the installation height of prism 420 is adjustable to precisely control the direction of light propagation, adapting to different sizes of test pieces and testing requirements, thus improving the flexibility and versatility of the testing device.

[0097] In some embodiments, such as Figure 5 As shown, one of the mounting base 410 and the second mounting member 440 is provided with a third connecting hole in the shape of an elongated strip, and the other of the mounting base 410 and the second mounting member 440 is provided with different third mounting holes. That is, by cooperating with the third connecting hole and the different third mounting holes, the first mounting member 430 is height-adjustably set on the mounting base 410, so as to realize the angle adjustment of the prism 420.

[0098] In this embodiment, as Figure 5 As shown, the second connecting hole is provided on the first mounting member 430, the second mounting hole and the third mounting hole are both provided on the second mounting member 440, and the third connecting hole is provided on the mounting base 410.

[0099] In some embodiments, such as Figure 5 As shown, the mounting base 410 includes a vertical section and a horizontal section, and the prism 420 is mounted on the upper end of the vertical section; one end of the horizontal section is connected to the lower end of the vertical section, and the extension direction of the horizontal section intersects the arrangement direction of the two mounting bases 410.

[0100] It is understandable that the horizontal segment extends along the first horizontal direction, and by connecting the end of the horizontal segment to the lower end of the vertical segment, i.e., the mounting base 410 is L-shaped, the stability of the mounting base 410 is improved to ensure the support strength of the prism 420.

[0101] In some embodiments, such as Figure 4 As shown, the detection device also includes a sensing element and multiple proximity sensors 500. The sensing element is disposed on the positioning fixture 100; the proximity sensors 500 are disposed on the base 200 and are used to determine the rotation angle of the positioning fixture 100 based on the sensing element. It should be noted that the number and specific distribution of the proximity sensors 500 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0102] It is understandable that when the installation platform 110 is rotated by the rotary drive 300, the sensing element and different proximity sensors 500 are coordinated, thereby accurately determining the rotation angle of the positioning fixture 100, avoiding the influence of excessive rotation on the rotary drive 300, and improving detection efficiency and reliability.

[0103] In this embodiment, as Figure 4 As shown, proximity sensors 500 are respectively installed on the four sides near the base 200.

[0104] In some embodiments, such as Figure 4 As shown, the detection device also includes a movable drive unit 600, the drive end of which is connected to the base 200 and is used to drive the base 200 to move horizontally. The movable drive unit 600 includes, but is not limited to, a linear guide rail.

[0105] Understandably, by setting the moving drive 600 to move the base 200 in the horizontal direction (including at least one of the first and second horizontal directions), the detection device can cover a larger detection area, improving the flexibility and applicability of the detection. It also facilitates connection with previous and subsequent processes, providing greater flexibility and automation, making the detection process more efficient, accurate and safe.
