Although some manufacturers have adopted automated inspection equipment for optical glass, the current equipment has certain limitations, such as incomplete inspection, inability to automatically inspect both sides of optical glass, low inspection efficiency, and poor automation.

[0004] In other words, existing automated testing equipment for optical glass suffers from the problem of simultaneously failing to achieve both comprehensive testing and high testing efficiency. Utility Model Content

[0005] The main objective of this invention is to provide an automated testing device for optical glass, thereby solving the problem that existing automated testing devices for optical glass cannot simultaneously achieve both comprehensive testing and testing efficiency.

The second detection camera is movably arranged along the radial and Z-axis of the stage.

[0008] Furthermore, the flipping mechanism includes: a base, which is movably disposed along the radial direction of the stage; a bracket, which is disposed on the base; and a flipping component, which is movably disposed on the bracket along the Z-axis. The flipping component includes a driving part and a flipping part, and the driving part is drivenly connected to the flipping part to drive the flipping part to rotate.

[0009] Furthermore, the flipping part includes: a connecting plate, a driving part being driven to the center position of the connecting plate so that the connecting plate rotates around its central axis; and an arm structure, of which there are multiple arm structures, which are circumferentially spaced on the outer peripheral side of the connecting plate, and each arm structure has an adsorption structure on the side away from the connecting plate, with the adsorption surfaces of two adjacent adsorption structures perpendicular to each other.

[0010] Furthermore, the loading and unloading assembly also includes a QR code reader and a positioning camera. The picking arm is movable along at least the X, Y, and Z axes, and the positioning camera is movable along the Z axis.

[0013] Furthermore, the automated inspection equipment for optical glass also includes a recognition camera located between the tray transport assembly and the stage. The recognition camera is used to detect the state of the optical glass on the picking arm.

[0014] Furthermore, the stage is circular, and there are multiple support fixtures. These multiple support fixtures are spaced apart in the outer periphery of the stage, and each support fixture has at least two holes for placing optical glass.

[0015] Furthermore, the optical glass includes an optical waveguide sheet; and / or the automated inspection equipment also includes a control component electrically connected to the stage, loading / unloading components and inspection components.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0033] To address the problem that existing automated testing equipment for optical glass struggles to simultaneously achieve both comprehensive testing and high testing efficiency, this invention provides an automated testing device for optical glass.

[0034] like Figure 1 and Figure 2 As shown, the automated inspection equipment for optical glass includes a stage 10, a loading / unloading assembly 30, and an inspection assembly. The stage 10 is rotatably mounted, and a support fixture 20 is mounted on the stage 10. The loading / unloading assembly 30 includes a picking arm 31, which is used to load and unload optical glass. The loading / unloading assembly 30 and the inspection assembly are arranged around the outer periphery of the stage 10. The inspection assembly includes an inspection camera and a flipping mechanism. The inspection camera is used to take pictures of the optical glass on the support fixture 20 for inspection, and the flipping mechanism is used to flip the optical glass on the support fixture 20.

[0035] By setting up a picking arm 31, the picking arm 31 can load the optical glass to be inspected onto the carrier fixture 20, and can also remove the inspected optical glass from the carrier fixture 20 for unloading. This allows for both loading and unloading operations to be completed with a single picking arm 31, maximizing its utilization and automating the loading and unloading process, thus improving efficiency. It also avoids the need for two picking arms 31 to handle loading and unloading separately, saving workpieces and reducing costs. By setting up an inspection camera and a flipping mechanism, the flipping mechanism can flip the optical glass to be inspected, enabling automated inspection of both sides of the optical glass. This allows for appearance defect checks on both sides of the optical glass, such as checking for dirt, scratches, and chips, as well as surface structural damage, making the inspection more comprehensive.

[0036] Furthermore, the automated inspection equipment for optical glass of this application can efficiently and accurately inspect the double-sided quality of optical glass. It is suitable for optical glass production and inspection lines in fields such as optical communication, lidar, and AR / VR, significantly improving inspection efficiency and accuracy, reducing errors caused by manual operation, enabling the production line to operate 24 hours a day without interruption, maximizing the utilization efficiency of the equipment, and ensuring the consistency and reliability of the inspection results for each optical glass, thus providing a solid guarantee for product quality.

[0037] In a specific embodiment of this application, the aforementioned optical glass is an optical waveguide sheet 80. A flipping mechanism can be used to inspect the appearance defects and surface nanoimprint structures of optical waveguide sheets 80 of different sizes and shapes, thereby detecting whether there are appearance defects (dirt, scratches, chips, etc.) and damage to the nanoimprint structure on both sides of the optical waveguide sheet 80. This has the advantage of handling multiple models with a single device, reducing personnel requirements and the error rate of manual inspection.

[0038] like Figure 2 , Figures 8 to 11 As shown, the detection assembly includes a front detection assembly and a back detection assembly. The back detection assembly is located downstream of the front detection assembly. The front detection assembly includes a first detection camera 51 and a first flipping mechanism 52. The first flipping mechanism 52 is located downstream of the first detection camera 51. The first detection camera 51 is movably arranged along the radial and Z-axis of the stage 10. The back detection assembly includes a second detection camera 53 and a second flipping mechanism 54. The second flipping mechanism 54 is located downstream of the second detection camera 53. The second detection camera 53 is movably arranged along the radial and Z-axis of the stage 10. During operation, the loading and unloading assembly 30 is located upstream of the first inspection camera 51. The picking arm 31 loads the optical glass to be inspected from the tray onto the carrier fixture 20. As the stage 10 rotates, the optical glass to be inspected in the carrier fixture 20 moves to the inspection station of the first inspection camera 51. Then, the first inspection camera 51 moves above the optical glass and takes a picture of the front of the optical glass. Then, the stage 10 continues to rotate until it reaches the station of the first flipping mechanism 52. The first flipping mechanism 52 flips the optical glass that has completed the front inspection so that the back of the optical glass faces the front. Then, it is placed in the carrier fixture 20. Then, as the stage 10 rotates, the optical glass is transferred to the inspection station of the second inspection camera 53. The second inspection camera 53 takes a picture of the back of the optical glass, thereby completing the double-sided inspection of the optical glass. Then, the stage 10 continues to rotate, causing the optical glass that has completed double-sided inspection to rotate to the position of the second flipping mechanism 54. The second flipping mechanism 54 flips the optical glass so that the front side is facing up, and then places it in the carrier fixture 20. Finally, the carrier fixture 20 rotates to the position corresponding to the loading and unloading assembly 30, and the unloading action is realized by the picking arm 31.

[0039] In summary, this setup enables the equipment to continuously inspect both the front and back sides of optical glass, further improving inspection efficiency. It is suitable for optical glass requiring high-precision double-sided inspection, such as waveguide sheets, lenses, and prisms, ensuring high-quality product output. In practical applications, this design significantly shortens the inspection cycle for optical glass and reduces inconsistencies caused by manual operation. Especially in the manufacturing process of optical communication equipment, it effectively improves product yield and reduces production costs.

[0040] Specifically, the front detection component and the back detection component have the same structure but different functions. More specifically, the first detection camera 51 and the second detection camera 53 have the same structure but different functions. The first detection camera 51 is used to photograph and detect the front of the optical glass to be detected, while the second detection camera 53 is used to photograph and detect the back of the optical glass to be detected. The first flipping mechanism 52 and the second flipping mechanism 54 have different structures and functions. The first flipping mechanism 52 is used to flip the optical glass that is facing up to face down, while the second flipping mechanism 54 is used to flip the optical glass that is facing down to face up.

[0041] The specific structural components of the flipping mechanism are described below with reference to the accompanying drawings.

[0042] Figure 9 and Figure 11 The first flipping mechanism 52 and the second flipping mechanism 54 are shown respectively. Since they have the same composition, the flipping mechanism will be used directly in the following description. That is to say, the flipping mechanism in the following description can be either the first flipping mechanism 52 or the second flipping mechanism 54.

[0043] like Figure 9 and Figure 11 As shown, the flipping mechanism includes a base 61, a support frame 62, and a flipping element 63. The base 61 is movably disposed along the radial direction of the platform 10. The support frame 62 is disposed on and connected to the base 61, and moves with the base 61. The support frame 62 has a track extending along the Z-axis. The flipping element 63 is movably disposed on the track of the support frame 62 along the Z-axis. The flipping element 63 includes a drive unit 631 and a flipping unit 632. The drive unit 631 is drivenly connected to the flipping unit 632 to drive the flipping unit 632 to rotate. In an optional embodiment of this application, the drive unit 631 may be a motor with an output shaft, and the flipping unit 632 is connected to the output shaft of the motor.

[0044] Specifically, the flipping part 632 includes a connecting plate 6321 and an arm structure 6322. The driving part 631 is driven to the center of the connecting plate 6321, so that the connecting plate 6321 rotates around its central axis. Multiple arm structures 6322 are arranged circumferentially around the connecting plate 6321 on its outer peripheral side. The arm structures 6322 can be integrally formed with the connecting plate 6321. Each arm structure 6322 has an adsorption structure 6323 on its side away from the connecting plate 6321, and the adsorption surfaces of two adjacent adsorption structures 6323 are perpendicular to each other. Specifically, the adsorption structure 6323 is located on the side of the arm structure 6322, and the adsorption surface of the adsorption structure 6323 is parallel to the extending direction of the arm structure 6322 it is located on.

[0045] Depend on Figure 9 and Figure 11 As shown in the figure, in a specific embodiment of this application, three arm structures 6322 can be provided, arranged in a "T" shape. As can be seen from the figure, the multiple arm structures 6322 rotate around the R-axis, and the adsorption surfaces of the adsorption structures 6323 on each arm structure 6322 are all oriented towards the direction of rotation. This design ensures the stability and safety of the optical glass during the flipping process, and is suitable for the inspection of fragile, high-precision optical glass, such as optical waveguide sheets 80, reducing the risk of damage to the optical glass during the inspection process.

[0046] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the loading / unloading assembly 30 also includes a QR code reader 32 and a positioning camera 33. The picking arm 31 is movably arranged along at least the X-axis, Y-axis, and Z-axis, and the positioning camera 33 is movably arranged along the Z-axis. The picking arm 31 is located between the QR code reader 32 and the positioning camera 33. Specifically, the loading / unloading assembly 30 also includes a bracket 34, which is located on the outer periphery of the stage 10. The bracket 34 has a slide rail that extends along the Y-axis direction, and the picking arm 31, the QR code reader 32, and the positioning camera 33 are slidably arranged on the slide rail. In a specific embodiment of this application, the picking arm 31 can also adjust the level of the optical glass it picks up.

[0047] refer to Figure 6 and Figure 7 As shown, the QR code reader 32 is used to identify the product information of the optical glass and upload the product information to the MES. The positioning camera 33 is used for positioning guidance of the picking arm 31 before picking up materials and for positioning guidance of materials onto the carrier fixture 20. The combination of the QR code reader 32 and the positioning camera 33 improves the accuracy and speed of loading and unloading, making it suitable for large-scale production environments such as optical communication equipment manufacturing and optical instrument production, ensuring the continuity and stability of the production line. In actual production, the QR code reader 32 can quickly and accurately identify the unique identifier of each optical glass, and the positioning camera 33 can accurately locate the position of the optical glass on the carrier fixture 20. This design greatly improves the efficiency and accuracy of loading and unloading, ensuring the correct detection and recording of each optical glass on the production line.

[0048] like Figure 2 and Figure 3As shown, the automated inspection equipment for optical glass also includes a tray transport assembly 70, which is located between the loading / unloading assembly 30 and the stage 10. Specifically, at least a portion of the tray transport assembly 70 is located below the support 34. The tray transport assembly 70 includes a guide rail extending along the X-axis, at least two trays, and multiple clamping cylinders 73. At least two trays are slidably mounted on the guide rail, and each tray has clamping cylinders 73 on at least two sides for clamping and fixing the tray. Each tray has multiple holes for placing optical glass. In a specific embodiment of this application, there are two trays, namely a first tray 71 and a second tray 72. The first tray 71 has multiple contoured holes that match the shape and size of the optical glass to be placed. The first tray 71 can be filled with optical glass to be inspected according to the number of contoured holes. The holes after unloading are automatically used as the placement holes for qualified products after inspection. The second tray 72 has the same structure as the first tray 71. The second tray 72 is an empty tray and is used to place defective products that have completed the inspection.

[0049] Specifically, the tray transport assembly 70 enables efficient transport and positioning of optical glass, suitable for batch inspection of optical glass, such as the production inspection of optical waveguide sheets 80, improving the continuity and automation level of inspection. In practical applications, the tray transport assembly 70 can continuously transport the optical glass to be inspected to the inspection position, and simultaneously transport both qualified and unqualified optical glass to the unloading position, avoiding the inefficiency and errors caused by manual handling. Especially in the production inspection of optical waveguide sheets 80, it enables efficient and accurate inspection of optical waveguide sheets 80, improving the continuity and automation level of inspection, and is suitable for large-scale, high-efficiency production environments.

[0050] like Figure 2 and Figure 5As shown, the automated inspection equipment for optical glass also includes a recognition camera 40, located between the tray transport assembly 70 and the stage 10. The recognition camera 40 is used to detect the state of the optical glass on the picking arm 31. Specifically, the recognition camera 40 detects whether there is optical glass on the picking arm 31 and whether the optical glass is square. The recognition camera 40 is also equipped with an alarm structure; when the picking arm 31 completes picking up material, but the recognition camera 40 detects no optical glass on the picking arm 31, the alarm is activated. The recognition camera 40 is configured to monitor the state of the optical glass in real time, ensuring the accuracy and reliability of the inspection. In actual production, the recognition camera 40 can monitor the state of the optical glass on the picking arm 31 in real time, promptly detect and correct problems such as offset and tilt of the optical glass, ensuring that each piece of optical glass can be accurately placed on the support fixture 20. It is suitable for environments with extremely high production precision requirements, such as the manufacture of precision optical instruments, and can significantly improve the accuracy and reliability of inspection, providing strong assurance for product quality.

[0051] like Figure 2 As shown, the stage 10 has multiple support fixtures 20, which are spaced apart on the outer periphery of the stage 10. Each support fixture 20 has at least two holes for placing optical glass, and these holes are matched to the size and shape of the optical glass. When it is necessary to inspect optical glass of different shapes and sizes, the tray and support fixture 20 can be replaced accordingly, which helps to ensure the compatibility and versatility of the automated inspection equipment, eliminating the need for dedicated machines and reducing costs. In a specific embodiment of this application, there are five support fixtures 20, each with two holes, so that the two holes can be used to place the optical glass with the front and back facing up, respectively.

[0052] refer to Figure 1 and Figure 2 As shown, the automated testing equipment also includes a control component. This control component is electrically connected to the stage 10, the loading / unloading component 30, the testing component, the tray transport component 70, and the recognition camera 40. In other words, the control component is electrically connected to all components in the automated testing equipment to rationally control the timing and operating status of each component, ensuring the stable operation of the automated testing equipment. The automated testing equipment also includes a housing 90, which has an accommodating space. The aforementioned control component, stage 10, loading / unloading component 30, testing component, tray transport component 70, and recognition camera 40 are all housed within this accommodating space, thus protecting each component and preventing external dust and dirt from affecting the testing results.

[0053] Specifically, a platform surface is provided in the housing 90. The aforementioned platform 10, loading and unloading assembly 30, front detection assembly, back detection assembly, material tray transport assembly 70 and recognition camera 40 are all set on the platform surface. The surface enclosed by the X-axis and Y-axis is located on the platform surface. The aforementioned Z-axis refers to the height direction relative to the platform surface.

[0054] This configuration helps ensure the balance and stability of each component, thus guaranteeing reliable operation.

[0055] In a specific embodiment of this application, the length * width * height of the automated testing equipment is 2000mm * 1600mm * 2000mm, the housing 90 is made of metal frame, and the platform surface is made of marble tabletop. This can effectively reduce vibration and ensure the movement accuracy of each component.

[0056] The following describes the specific operational procedures of the automated inspection equipment for optical glass described in this application:

[0057] Step 1: The material handling arm 31 moves above the first material tray 71 and descends to a suitable height. The QR code reader 32 identifies the product information of the optical waveguide sheet 80 in the first material tray 71 and uploads it to the MES system.

[0058] Step 2: Positioning camera 33 takes a picture of optical waveguide sheet 80 to identify the position of optical waveguide sheet 80, and picking arm 31 descends and picks up optical waveguide sheet 80.

[0059] Step 3: The stage 10 is circular and rotatable. When the stage 10 rotates to the receiving position, the positioning camera 33 photographs the position of the support fixture 20 on the stage 10, identifies the desired placement location of the optical waveguide sheet 80, and controls the picking arm 31 to place the picked-up optical waveguide sheet 80 into a hole in the support fixture 20. It should be noted that when the picking arm 31 finishes picking up material, the identification camera 40 detects whether there is any product on the picking arm 31, whether the product is placed correctly, and issues an alarm if there is no material.

[0060] Step 4: The stage 10 continues to rotate, and the support fixture 20, which was used for loading in step 3, rotates to the front inspection station. At the same time, the rear support fixture 20 rotates to the receiving position. The first inspection camera 51 moves to the inspection position to perform front-side appearance defect inspection on the optical waveguide sheet 80 in the support fixture 20. Step 4 is performed simultaneously with steps 1, 2, and 3.

[0061] Step 5: After the front inspection is completed, the stage 10 continues to rotate to the first flipping mechanism 52, and at the same time, the newly added optical waveguide sheet 80 moves to the position corresponding to the first inspection camera 51, and the empty carrier fixture 20 moves to the receiving position.

[0062] Step 6: The arm structure 6322 of the first flipping mechanism 52 uses a combination of rotating around the R-axis, lifting and lowering around the Z-axis, and moving forward and backward around the Y-axis to pick up the optical waveguide sheet 80 that has been tested at the upper station. Then, through a combination of rotating around the R-axis, lifting and lowering around the Z-axis, and moving forward and backward around the Y-axis, the flipped optical waveguide sheet 80 is placed in another hole of the carrying fixture 20.

[0063] Step 7: After the preceding station completes its operation, the stage 10 continues to rotate, and the initial optical waveguide sheet 80 reaches the back inspection station. At the same time, the preceding station repeats the operation steps that should be performed.

[0064] Step 8: The second inspection camera 53 moves to the inspection position to inspect the appearance defects on the other side of the optical waveguide sheet 80.

[0065] Step 9: After the inspection is completed, the stage 10 continues to rotate, and the product reaches the corresponding position of the second flipping mechanism 54. The second flipping mechanism 54 flips the optical waveguide 80 to the initial hole position.

[0066] Step 10: For waveguide sheets 80 that pass both inspections, the material handling arm 31, after identifying the specific feeding position via the positioning camera 33, picks up the qualified sheets and places them in the first empty slot of the first tray 71. Subsequent qualified sheets are placed in the same manner. Waveguide sheets 80 that fail the inspection are placed in the second tray 72.

[0067] At this point, the inspection process for the optical waveguide sheet 80 is complete. Once all untested products in the first tray 71 have been inspected, the inspection of all products in the first tray 71 will be finished. The new first tray 71 will then continue operating. The second tray 72 can be replaced simultaneously with an empty tray, or it can be replaced only when it is full.

[0068] In summary, the automated inspection equipment for optical glass provided in this application, through the cooperation of the stage 10, the loading / unloading assembly 30, and the inspection assembly, realizes the automated loading, inspection, and unloading process of optical glass, improving inspection efficiency and accuracy. In particular, the flipping mechanism enables automatic flipping of the optical glass for double-sided inspection, avoiding manual intervention, reducing inspection costs, and improving production efficiency. Furthermore, the equipment has a reasonable structural design, stable operation, and is suitable for large-scale production environments, significantly promoting improved product quality and production automation levels.
