Description

Technical Field

[0001] The present invention relates to the technical field of lens surface defect detection, and in particular to a device for detecting surface defects of VR lenses. Background Art

[0002] To achieve comprehensive, high-precision inspection of VR lenses, traditional methods typically require testing both sides of the lens separately, which inevitably involves flipping the lens. Furthermore, to obtain more comprehensive information, the lens must be illuminated from the side at a specific angle and analyzed based on the image captured from the opposite side.

[0003] However, the arrangement of multiple light sources not only increases the cost of the equipment, but also makes the optical path adjustment extremely complicated. In order to allow the light to illuminate the lens in all directions, the lens needs to be adjusted multiple times during the detection process, and the operation of removing and re-clamping the lens is also involved. This series of tedious steps not only consumes a lot of time, causing the equipment to idle and wait, reducing the detection efficiency, but also each re-clamping may introduce new errors, affecting the accuracy of the detection. More importantly, during the adjustment process, the frequent light changes and brightness adjustments seriously interfere with the stability and reliability of the detection for equipment that relies on light irradiation for detection. Based on this, the present invention purposely provides a device for VR lens surface defect detection that can perform all-round irradiation detection on the lens through a single light source. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for detecting surface defects of VR lenses in order to address the shortcomings of the prior art and solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A device for detecting surface defects of VR lenses, comprising:

[0007] A base, wherein a mounting seat is fixedly mounted on the base, a rotating ring is rotatably mounted on the mounting seat, the rotating ring is driven to rotate by an output source built into the mounting seat, a first electric cylinder is fixedly mounted on the rotating ring, a first output source is fixedly mounted on a movable end of the first electric cylinder, a loading frame is fixedly mounted on an output end of the first output source, clamps are slidably mounted on all four sides of the loading frame, the clamps are driven to move by a first driving source, and the four clamps are used to clamp and fix the lens;

[0008] A light source assembly is slidably mounted on the base and driven by a second driving source built into the base to move along the radial direction of the rotating ring;

[0009] The top plate is fixedly mounted on the base, and a camera assembly is fixedly mounted on the bottom of the top plate. The camera assembly is coaxially arranged with the rotating ring, and the object loading frame is located between the camera assembly and the light source assembly. When the lens is inspected, the lens is in a horizontal state, and the lens, light source assembly and camera assembly are coaxially arranged.

[0010] As a further solution of the present invention: a loading area is provided on the base, and a pallet is slidably installed on the base. The pallet is located in the loading area, and the pallet is driven to rise and fall by a third driving source. When the first electric cylinder contracts so that the loading frame is located directly above the pallet, the third driving source drives the pallet to rise and abut against the bottom of the loading frame.

[0011] As a further solution of the present invention: a lifting seat is provided on the top plate, and two air blowing pipes are fixedly installed on the bottom of the lifting seat, and a gap is formed between the two air blowing pipes. When the first output source drives the carrier frame to rotate so that the lens is in a vertical state, the first electric cylinder extends to drive the carrier frame through the gap.

[0012] As a further solution of the present invention: the lifting seat is slidably installed on the top plate, and the lifting seat is driven by a fourth driving source to perform lifting motion.

[0013] As a further solution of the present invention: a discharge port is provided on the base, and when the lens is restored to a horizontal state after detection, the first electric cylinder drives the loading frame to move so that the distance between the lens and the axis of the rotating ring is consistent with the distance between the discharge port and the axis of the rotating ring, and the rotating ring rotates to drive the first electric cylinder to move so that the lens is located directly above the discharge port.

[0014] As a further solution of the present invention, the number of the blanking ports is three, and the three blanking ports are arranged circumferentially, and the three blanking ports correspond to qualified, reworked and unqualified lenses in sequence.

[0015] As a further solution of the present invention: each unloading port has a second electric cylinder corresponding to a unloading plate, the second electric cylinder is fixedly installed on the bottom plate of the base, the second electric cylinder is located directly below the unloading port, and the unloading plate is fixedly installed on the movable end of the second electric cylinder. When the lens moves to directly above the unloading port, the second electric cylinder extends to drive the unloading plate to abut against the loading frame.

[0016] As a further solution of the present invention: the distance between the support plate and the axis of the rotating ring is consistent with the distance between the discharge port and the axis of the rotating ring.

[0017] Beneficial effects of the present invention:

[0018] 1. In the present invention, the carrier frame that clamps and fixes the lens can be flipped, thereby realizing basic defect detection on both sides of the lens. By flipping the carrier frame at a certain angle, the lens axis and the light emitted by the light source assembly form an angle, and the light source assembly can be translated so that the light it emits illuminates the side of the lens. The rotating ring drives the rotation of the first electric cylinder and the carrier frame, causing the lens to rotate around the axis of the rotating ring. In this way, the light can illuminate the side of the lens in all directions, thereby realizing all-round surface defect detection. There is no need to re-clamp and fix the lens during the entire process, which not only avoids long waiting times but also avoids errors that may occur during repositioning, thereby improving the efficiency of single detection. In addition, the light of the single light source assembly during the entire process also simplifies the adjustment of the optical path during detection.

[0019] 2. In the present invention, a lifting pallet is provided. When loading is required, the loading frame is moved to the top of the pallet, and then the third driving source drives the pallet to rise and abut against the bottom of the loading frame. Subsequently, the lens is placed on the pallet, that is, in the middle of the loading frame, and then the lens is clamped and fixed by four clamps. When the clamps touch the lens, they push the lens to slide on the pallet, and finally the lens and the loading frame are coaxial, and the loading task is completed. In this way, the lens loading work can be completed simply and quickly without the need for precise instruments or cumbersome operations, thereby improving the efficiency and accuracy of loading.

[0020] 3. In the present invention, lenses can be classified into three categories according to their inspection results: qualified, reworked, and unqualified, which respectively mean that they can enter the next process, need to reprocess the surface, and are discarded as waste. Therefore, three unloading ports are set, corresponding to qualified, reworked, and unqualified lenses respectively. After the inspection is completed, the loading frame is directly moved to the corresponding unloading port, and then the lens falls into the corresponding unloading port. In this way, the classification of the lenses can be completed in the unloading stage, avoiding the problem of lenses with different inspection results being mixed together, which makes classification difficult, and realizes a clear and definite inspection process.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 As shown, the present invention is a device for detecting surface defects of VR lenses, comprising:

[0032] A base 1, a mounting seat 2 is fixedly mounted on the base 1, a rotating ring 3 is rotatably mounted on the mounting seat 2, the rotating ring 3 is driven to rotate by an output source built into the mounting seat 2, a first electric cylinder 4 is fixedly mounted on the rotating ring 3, a first output source 5 is fixedly mounted on the movable end of the first electric cylinder 4, a loading frame 6 is fixedly mounted on the output end of the first output source 5, clamps 7 are slidably mounted on all four sides of the loading frame 6, the clamps 7 are driven to move by a first driving source, and the four clamps 7 are used to clamp and fix a lens 8;

[0033] A light source assembly 9 is slidably mounted on the base 1 and driven by a second driving source built into the base 1 to move along the radial direction of the rotating ring 3;

[0034] The top plate 10 is fixedly mounted on the base 1, and a camera assembly 11 is fixedly mounted on the bottom of the top plate 10. The camera assembly 11 is coaxially arranged with the rotating ring 3, and the object frame 6 is located between the camera assembly 11 and the light source assembly 9. When the lens 8 is inspected, the lens 8 is in a horizontal state, and the lens 8, the light source assembly 9 and the camera assembly 11 are coaxially arranged.

[0035] In one case of this embodiment, the first driving source and the second driving source can both be selected from electric cylinders, electric telescopic rods and other components, and other mechanisms that can realize linear reciprocating motion can also be selected. The output source and the first output source 5 can both be selected from servo motors, pulley assemblies, and gear and ring gear meshing transmission assemblies, etc., and other mechanisms that can realize rotational motion can also be selected. This embodiment does not make specific limitations here; it should be noted that the light source assembly 9 described in the present invention includes a coaxial light source, a light source controller, etc., and the top plate 10 includes image sensors, cameras, image processors and other components. The above components and the first electric cylinder 4 are all existing technologies, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0036] The working principle of the present invention is: first, the lens 8 is loaded, and the specific operation is: control the first electric cylinder 4 to contract, so that the loading frame 6 is close to the edge of the rotating ring 3. At this time, a manual or robotic arm places the lens 8 to be inspected in the middle of the loading frame 6, and then starts the four first driving sources to drive the clamps 7 to clamp and fix the lens 8, that is, the loading is completed. At this time, the axis of the lens 8 coincides with the axis of the loading frame 6, and the lens 8 is also coaxial with the camera assembly 11. Then, the first electric cylinder 4 is controlled to extend so that the lens 8 moves to a position that coincides with the axis of the rotating ring 3. The purpose is to allow the output source to drive the rotating ring 3 to rotate, and the lens 8 will rotate by itself. Then, the light source assembly 9 is driven to move by the second driving source, so that the light source emitted by the light source assembly 9 is coaxial with the lens 8, and then surface defect detection can be started.

[0037] First, turn on the light source component 9 under the premise of ensuring that there are no other light sources in the detection environment. The light emitted by the light source component 9 passes through the lens 8 from below. At this time, the camera component 11 takes and analyzes the image of the top surface of the lens 8 to check whether there are defects such as scratches and burrs, and records the situation. Subsequently, the first output source 5 drives the object frame 6 to flip one hundred and eighty degrees, so that the lens 8 is turned over. At this time, the camera component 11 can detect and record the other side of the lens 8. The conventional two-sided defect detection of the lens 8 by light irradiation is completed. Next, the side of the lens 8 is inspected by irradiating light. Here, it means to let the light shine on the lens 8 at a certain angle. This is to distinguish between concave and convex defects, and the light is incident from the side, which can highlight edge defects such as broken edges and uneven chamfers that are difficult to capture with traditional vertical light. The specific operations are as follows.

[0038] First, the first output source 5 drives the loading frame 6 to rotate a certain angle, so that the axis of the lens 8 forms an angle with the light emitted by the light source component 9, and then the second driving source drives the light source component 9 to move along the radial direction of the rotating ring 3. At this time, the light emitted by the light source component 9 is irradiated onto the side of the lens 8. The two steps of moving the light source component 9 and rotating the loading frame 6 can be interchanged and can be designed according to actual production needs. Then, the rotating ring 3 is controlled to rotate so that the light can illuminate a circle of the lens 8. During this process, the camera component 11 continuously captures images and records the degree of defects. Finally, the three records are combined to determine whether the lens 8 is qualified, reworked or unqualified. Then, the lens 8 can be cut and then replaced with a new lens 8 to be tested to start the next round of testing.

[0039] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, a loading area is provided on the base 1, and a pallet 13 is slidably mounted on the base 1. The pallet 13 is located in the loading area, and the pallet 13 is driven to rise and fall by a third driving source. When the first electric cylinder 4 contracts so that the loading frame 6 is located directly above the pallet 13, the third driving source drives the pallet 13 to rise and abut against the bottom of the loading frame 6.

[0040] In one case of this embodiment, the third driving source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0041] In actual application of this embodiment, considering that the loading frame 6 is hollow, the lens 8 is suspended in the middle of the loading frame 6 waiting to be clamped by the clamping plate 7. The operation needs to be very delicate and cumbersome. Therefore, a lifting support plate 13 is provided. When loading is required, the loading frame 6 is moved to the top of the support plate 13, and then the third driving source drives the support plate 13 to rise and abut against the bottom of the loading frame 6. Then, the lens 8 is placed on the support plate 13, that is, in the middle of the loading frame 6, and then the lens 8 is clamped and fixed by four clamping plates 7. When the clamping plate 7 touches the lens 8, it will push the lens 8 to slide on the support plate 13, and finally make the lens 8 coaxial with the loading frame 6, and complete the loading task. In this way, the loading of the lens 8 can be completed simply and quickly without the need for precise instruments or cumbersome operations, thereby improving the efficiency and accuracy of loading.

[0042] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, a lifting seat 14 is provided on the top plate 10, and two air blowing pipes 15 are fixedly installed on the bottom of the lifting seat 14, and a gap 16 is formed between the two air blowing pipes 15. When the first output source 5 drives the carrier frame 6 to rotate so that the lens 8 is in a vertical state, the first electric cylinder 4 extends to drive the carrier frame 6 to pass through the gap 16.

[0043] In one case of this embodiment, the air blowing pipe 15 is connected to an external blowing device, and the air blowing pipe 15 blows out plasma wind to clean the surface of the lens 8.

[0044] In actual application of this embodiment, since impurities on the lens 8 may be mistakenly regarded as defects by the camera component 11, before inspecting the lens 8, the first output source 5 drives the loading frame 6 to rotate so that the lens 8 is in a vertical state, and the first electric cylinder 4 extends to drive the loading frame 6 to pass through the gap 16. At this time, the plasma wind blown out by the blowing pipe 15 can clean the surface of the lens 8 and blow away the surface impurities, thereby avoiding the problem of the presence of impurities interfering with the detection results.

[0045] like Figure 5 As shown, as a preferred embodiment of the present invention, the lifting seat 14 is slidably installed on the top plate 10, and the lifting seat 14 is driven by a fourth driving source to perform lifting motion.

[0046] In one case of this embodiment, the fourth driving source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0047] In actual application of this embodiment, when the lens 8 is located in the gap 16 between the two lifting seats 14, the fourth driving source can be used to drive the lifting seats 14 to descend, so that the air blowing pipe 15 can be used to blow the surface of the lens 8 from top to bottom to ensure that the lens 8 is thoroughly cleaned. In addition, the first output source 5 can be used to drive the loading frame 6 to rotate slightly to tilt the lens 8, so that the air blowing pipe 15 can be closer to the surface of the lens 8, allowing a stronger airflow to blow to the surface of the lens 8, thereby improving the cleaning effect of impurities on the surface of the lens 8.

[0048] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, a discharge port 12 is opened on the base 1. When the lens 8 returns to a horizontal state after the inspection is completed, the first electric cylinder 4 drives the loading frame 6 to move so that the distance between the lens 8 and the axis of the rotating ring 3 is consistent with the distance between the discharge port 12 and the axis of the rotating ring 3. The rotating ring 3 rotates to drive the first electric cylinder 4 to move so that the lens 8 is located directly above the discharge port 12.

[0049] In actual application of this embodiment, a discharge port 12 is opened on the base 1. When the lens 8 returns to a horizontal state after the inspection is completed, the first electric cylinder 4 drives the loading frame 6 to move, so that the distance between the lens 8 and the axis of the rotating ring 3 is consistent with the distance between the discharge port 12 and the axis of the rotating ring 3. The rotating ring 3 rotates to drive the first electric cylinder 4 to move so that the lens 8 is located directly above the discharge port 12. Then the first driving source drives the splint 7 to contract and release the clamping of the lens 8. At this time, the lens 8 will fall to the discharge port 12 to complete the discharge. There is no need to manually remove the lens 8 from the loading frame 6, which increases the discharge speed, thereby shortening the time of the single lens 8 inspection process and improving the inspection efficiency.

[0050] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the number of the blanking ports 12 is three, and the three blanking ports 12 are arranged circumferentially, and the three blanking ports 12 correspond to qualified, reworked and unqualified lenses 8 in sequence.

[0051] In actual application, this embodiment can be divided into three types according to the inspection results of the lenses 8: qualified, reworked and unqualified, which respectively mean that they can enter the next process, need to reprocess the surface and are discarded as waste. Therefore, three discharge ports 12 are set, corresponding to qualified, reworked and unqualified lenses 8 respectively. After the inspection is completed, the loading frame 6 is directly moved to the corresponding discharge port 12, and then the lenses 8 fall into the corresponding discharge port 12. In this way, the classification of the lenses 8 can be completed in the discharge stage, avoiding the problem of lenses 8 with different inspection results being mixed together to cause classification difficulties, and realizing a clear and definite inspection process.

[0052] like Figure 4-Figure 6 As shown, as a preferred embodiment of the present invention, each discharge port 12 has a second electric cylinder 17 and a corresponding discharge plate 18, the second electric cylinder 17 is fixedly installed on the bottom plate of the base 1, the second electric cylinder 17 is located directly below the discharge port 12, and the discharge plate 18 is fixedly installed on the movable end of the second electric cylinder 17. When the lens 8 moves to directly above the discharge port 12, the second electric cylinder 17 extends to drive the discharge plate 18 to abut against the loading frame 6.

[0053] In one case of this embodiment, each of the second electric cylinders 17 can be surrounded by mechanical claws to assist in unloading, and a vacuum suction cup can be used to suck up the lens 8, and a conveyor belt can be equipped to transport the lens 8 out of the base 1. It should be noted that the second electric cylinders 17 described in the present invention are prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0054] In actual application of this embodiment, before the clamping plate 7 is released to fix the lens 8, the second electric cylinder 17 extends to drive the blanking plate 18 to abut the loading frame 6. At this time, the lens 8 is located on the blanking plate 18. Then the clamping plate 7 to the lens 8 is released, and then the second electric cylinder 17 contracts. The blanking plate 18 will support the lens 8 from the blanking port 12 to complete the blanking and classification operations, thereby avoiding the problem of the lens 8 falling directly from a high place into the blanking port 12 and causing damage, and each second electric cylinder 17 can be surrounded by a mechanical claw for auxiliary blanking, which can be used to suck the lens 8 in the form of a vacuum suction cup, and can be equipped with a conveyor belt to transport the lens 8 out of the base 1, ensuring that the lens 8 will not be damaged during the blanking stage, resulting in new defects on the surface, thereby affecting the detection accuracy.

[0055] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the distance between the support plate 13 and the axis of the rotating ring 3 is consistent with the distance between the discharge port 12 and the axis of the rotating ring 3.

[0056] When this embodiment is actually used, after the loading frame 6 completes unloading at the unloading port 12, the loading frame 6 is immediately loaded, and the distance between the support plate 13 and the axis of the rotating ring 3 is consistent with the distance between the unloading port 12 and the axis of the rotating ring 3. At this time, the loading frame 6 can be directly rotated to the top of the support plate 13 by rotating the rotating ring 3, thereby connecting the loading operation. In this way, the unloading position can be used to eliminate the need to adjust the position of the loading frame 6 by extending and retracting the first electric cylinder 4, thereby enhancing the continuity of the unloading and loading operations and making the process of detecting the lens 8 smoother.

[0057] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
