Description

Technical Field

[0001] This invention relates to the field of lens inspection technology, and more specifically, to an automatic detection device for manufacturing defects in lenses used in mobile phone lenses. Background Technology

[0002] Currently, PE lenses used in mobile phone lens modules are prone to appearance defects such as black spots, bubbles, scratches, and defects after injection molding. In traditional production processes, lens cutting equipment lacks automatic inspection capabilities, relying heavily on manual inspection. Manual inspection suffers from low efficiency, high missed detection rates, high false detection rates, high labor costs, and inconsistent inspection standards, severely impacting production efficiency and product yield, and failing to meet the automated production requirements of modern intelligent manufacturing.

[0003] While some existing testing equipment is equipped with automated testing, most of the testing is done on one side. This makes it easy to miss defects such as oblique scratches, edge chipping, or localized coating defects from a single angle, leading to false acceptance. Summary of the Invention

[0004] This invention provides an automatic detection device for defects in the production of lenses for mobile phone lenses, which solves the technical problem in related technologies where the inability to perform multi-angle detection leads to the easy omission of defects such as oblique scratches, edge chipping, or local coating when detecting defects from a single angle, resulting in false judgments of acceptance.

[0005] This invention provides an automatic detection device for defects in the production of lenses for mobile phone lenses, including a frame and a lifting unit located on the right side of the frame. The lifting unit is controlled by a servo motor at its top. The output end of the lifting unit is connected to a fixture rotation unit via a connecting seat. The fixture rotation unit is provided with a fixture flipping unit and a detection and pressing unit at its rear and top, respectively. A detection unit is provided at the top left side of the frame.

[0006] The fixture rotation unit includes a drive base fixedly connected to the connecting base, and a drive motor fixedly connected to the bottom of the drive base. The output shaft of the drive motor passes through the top of the drive base and is fixedly connected to a fixture disk. An encoder disk is fixedly connected to the surface of the output shaft of the drive motor, and a sensor is fixedly connected to the bottom of the drive base.

[0007] A material tray is placed on the top of the fixture tray, and the material tray is composed of a connecting cylinder, a connecting rod and a fixing ring. A flipping assembly is provided between the material tray and the drive seat. The flipping assembly includes a toothed sleeve fixedly connected to the outside of the connecting rod. A fixing cylinder is fixedly connected to the upper end of the drive seat, and a rack is fixedly connected to the rear end of the top of the fixing cylinder.

[0008] As a further optimization of the present invention, the toothed sleeve meshes with the rack, the length of the rack is one-third of the circumference of the toothed sleeve, and the connecting rod is rotatably connected to the connecting cylinder through a damping bearing.

[0009] As a further optimization of the present invention, the fixture flipping unit includes a flipping cylinder fixedly connected to the left side of the connecting seat, and the output shaft of the flipping cylinder is movably connected to the drive seat through a flipping connecting rod. A flipping limit seat is fixedly connected to the left side of the connecting seat, and the connecting seat and the drive seat are rotatably connected through a flipping bearing.

[0010] As a further optimization of the present invention, the detection and clamping unit includes a clamping cylinder fixedly connected to the top of the drive seat, and the output shaft of the clamping cylinder is fixedly connected to a first clamping connecting rod. The top of the first clamping connecting rod is rotatably connected to a pressure rod, and a second clamping connecting rod is movably connected between the pressure rod and the clamping cylinder. The bottom of the pressure rod is fixedly connected to a pressure block through a push rod.

[0011] As a further optimization of the present invention, the detection unit includes a slide cylinder fixedly connected to the top of the frame, and the output shaft of the slide cylinder is fixedly connected to a mounting bracket. The top of the mounting bracket is movably connected to a lifting cylinder through a height adjustment plate, and the output shaft of the lifting cylinder is fixedly connected to a vision camera. A lamp is fixedly connected to the right side of the mounting bracket. The vision camera and the mounting bracket are jointly covered by a light shield, and a supplementary light is provided on the inner wall of the lamp.

[0012] As a further optimization of the present invention, the inside of the material tray is provided with a dust removal component. The dust removal component includes a fixed seat fixedly connected to the inside of the connecting cylinder, and a fixed rod fixedly connected to the circumferential side of the fixed seat. A piston cylinder is movably connected inside the connecting rod. The fixed rod passes through the inside of the piston cylinder and is fixedly connected to a connecting plate. A first spring is fixedly connected between the connecting plate and the piston cylinder. A guide block is fixedly connected to the outside of the piston cylinder. A guide groove adapted to the guide block is opened on the inner wall of the connecting rod. A limit strip is fixedly connected to the surface of the fixed rod.

[0013] As a further optimization of the present invention, the guide grooves are arranged in three groups at equal intervals, and the guide grooves are composed of an inclined groove and a vertical groove connected together. The elastic force of the first spring is greater than the sliding friction between the piston cylinder and the connecting rod. The end of the connecting rod is open and connected to the fixing ring.

[0014] As a further optimization of the present invention, the bottom of the lamp tube is provided with a supplementary light angle adjustment component. The supplementary light angle adjustment component includes a toothed ring rotatably connected to the bottom of the lamp tube. The top of the toothed ring is provided with a groove, and an airbag ring is fixedly connected inside the groove. The inside of the lamp tube is provided with a movable groove that is narrow inside and wide outside. The supplementary light is placed inside the movable groove. One end of the supplementary light located inside the movable groove is rotatably connected to a lifting rod, and a second spring is fixedly connected between the top of the lifting rod and the movable groove.

[0015] As a further optimization of the present invention, the airbag ring is divided into multiple sacs with narrow channels between adjacent sacs, the elastic force of the second spring is greater than the weight of the lifting rod, and a toothed block that meshes with the toothed ring is fixedly connected to the outer side of the pressure block.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The automatic detection device for manufacturing defects of mobile phone lens described in this invention detects the lens from multiple angles by driving the connecting rod to rotate during the detection process. This avoids the omission of defects such as oblique scratches, edge chipping, or local coating under single-angle detection, thus improving the accuracy of detection.

[0018] 2. The automatic defect detection device for mobile phone lens manufacturing described in this invention drives the piston cylinder to reciprocate inside the piston cylinder by rotating the connecting rod. When the piston cylinder is displaced, it can draw external air into the interior of the connecting rod, and when the piston cylinder is reset, it can quickly squeeze the air out of the interior of the connecting rod, so that the air is quickly ejected from the opening at the end of the connecting rod. The resulting jet airflow blows on the lens surface and can blow away the floating dust on the lens surface, thereby ensuring the cleanliness of the lens surface and preventing floating dust from adhering to the lens surface and affecting the accuracy of lens appearance inspection.

[0019] 3. The automatic detection device for manufacturing defects of mobile phone lens described in this invention can detect the appearance of the lens under different irradiation angles by adjusting the angle of the supplementary light, thereby avoiding the difficulty in identifying the surface defects of the lens due to the coverage of reflected light caused by single-angle irradiation, and greatly improving the accuracy of lens surface defect detection.

[0040] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0041] like Figures 1 to 3 As shown in the figure, an automatic detection device for manufacturing defects of lenses for mobile phone lenses according to an embodiment of the present invention includes a frame 10 and a lifting unit 11 located on the right side of the frame 10. The lifting unit 11 is controlled by a servo motor 12 at its top. The output end of the lifting unit 11 is connected to a fixture rotation unit 14 through a connecting seat 13. A fixture flipping unit 15 is provided on the rear side of the fixture rotation unit 14. The servo motor 12 drives the lifting unit 11 to raise the connecting seat 13 to a predetermined height. When the connecting seat 13 rises, it drives the fixture rotation unit 14 and the fixture flipping unit 15 to rise synchronously.

[0042] The fixture rotation unit 14 includes a drive seat 145 fixedly connected to the connecting seat 13, and a drive motor 141 fixedly connected to the bottom of the drive seat 145. The output shaft of the drive motor 141 passes through the top of the drive seat 145 and is fixedly connected to a fixture disk 144. An encoder disk 142 is fixedly connected to the surface of the output shaft of the drive motor 141. A sensor 143 is fixedly connected to the bottom of the drive seat 145.

[0043] The fixture flipping unit 15 includes a flipping cylinder 151 fixedly connected to the left side of the connecting seat 13, and the output shaft of the flipping cylinder 151 is movably connected to the drive seat 145 through a flipping connecting rod 152. A flipping limit seat 153 is fixedly connected to the left side of the connecting seat 13. The connecting seat 13 and the drive seat 145 are rotatably connected through a flipping bearing 154. A detection and pressing unit 16 is provided on the top of the fixture rotating unit 14, and a detection unit 17 is provided on the top left side of the frame 10.

[0044] It should be noted that during the process of the drive seat 145 in the fixture rotation unit 14 being raised by the connecting seat 13, the output shaft of the tilting cylinder 151 extends and retracts, and the tilting connecting rod 152 drives the drive seat 145 to rotate with the connecting seat 13 via the tilting bearing 154, thereby tilting the drive seat 145 to a supporting posture to facilitate material reception. During the rotation, the tilting limit seat 153 limits the maximum rotation angle of the drive seat 145. After the material tray 18 falls onto the fixture tray 144 at the upper end of the drive seat 145, the detection and clamping unit 16 clamps the material tray 18. Then, the servo motor 12 drives the lifting unit 11 to lower the connecting seat 13 to the detection position. During the descent, the output shaft of the tilting cylinder 151 extends and retracts, pushing the drive seat 145 back to the water position. In a flat state, the detection unit 17 then detects the lenses on the tray 18. During the detection process, the drive motor 141 drives the fixture tray 144 to rotate the tray 18, making the tray 18 rotate 360 ​​degrees, thereby enabling the detection unit 17 to detect the lenses on the tray 18. While the drive motor 141 rotates, its output shaft drives the encoder tray 142 to rotate synchronously. The codes on the encoder tray 142 correspond one-to-one with the lenses on the tray 18. During the rotation, the sensor 143 identifies the codes on the encoder tray 142 one by one, which can provide real-time information on the rotation angle of the tray 18 and the detection results of the lenses on the tray 18, thereby avoiding missed detections and quickly finding the unqualified lenses on the tray 18 after the detection is completed.

[0045] like Figure 2 As shown, the detection and clamping unit 16 includes a clamping cylinder 161 fixedly connected to the top of the drive seat 145, and the output shaft of the clamping cylinder 161 is fixedly connected to a first clamping connecting rod 162. The top of the first clamping connecting rod 162 is rotatably connected to a pressure rod 164, and a second clamping connecting rod 163 is movably connected between the pressure rod 164 and the clamping cylinder 161. The bottom of the pressure rod 164 is fixedly connected to a pressure block 166 through a push rod 165.

[0046] It should be noted that when the detection and clamping unit 16 is used to clamp the material tray 18, the output shaft of the clamping cylinder 161 extends and pushes one end of the pressure rod 164 with the first clamping connecting rod 162. After the pressure rod 164 is subjected to force, it rotates with the connection point between itself and the second clamping connecting rod 163 as the fulcrum, thereby causing the other end of it to descend. The push rod 165 pushes the pressure block 166 from the top to cooperate with the fixture plate 144 to clamp and clamp the material tray 18, so as to avoid the material tray 18 from being displaced during the detection process, which would cause the detection result to be deviated.

[0047] like Figure 1 and Figure 4As shown, the detection unit 17 includes a slide cylinder 171 fixedly connected to the top of the frame 10, and the output shaft of the slide cylinder 171 is fixedly connected to a mounting bracket 172. The top of the mounting bracket 172 is movably connected to a lifting cylinder 175 through a height adjustment plate 174, and the output shaft of the lifting cylinder 175 is fixedly connected to a vision camera 176. A lamp tube 173 is fixedly connected to the right side of the mounting bracket 172. The vision camera 176 and the mounting bracket 172 are jointly covered by a light shield 177. A supplementary light 19 is provided on the inner wall of the lamp tube 173.

[0048] It should be noted that after the material tray 18 moves to the inspection area, the slide cylinder 171 pushes the mounting bracket 172 to move, so that the vision camera 176 and the lamp tube 173 move to directly above the lens. Then, the lifting cylinder 175 pushes the vision camera 176 down to dock with the lamp tube 173. The light shield 177 and the lamp tube 173 are used to block the ambient light, reducing the influence of ambient light on the inspection results. The supplementary light 19 on the inner wall of the lamp tube 173 illuminates the lens to provide brightness. Then, the vision camera 176 takes pictures of the lens to identify surface defects.

[0049] like Figure 5 As shown, a material tray 18 is placed on the top of the fixture tray 144, and the material tray 18 is composed of a connecting cylinder 181, a connecting rod 182, and a fixing ring 183. A flipping assembly 20 is provided between the material tray 18 and the drive seat 145. The flipping assembly 20 includes a toothed sleeve 22 fixedly connected to the outside of the connecting rod 182. A fixing cylinder 21 is fixedly connected to the upper end of the drive seat 145, and a rack 23 is fixedly connected to the rear end of the top of the fixing cylinder 21. The toothed sleeve 22 meshes with the rack 23. The length of the rack 23 is one-third of the circumference of the toothed sleeve 22. The connecting rod 182 is rotatably connected to the connecting cylinder 181 through a damping bearing.

[0050] It should be noted that during the testing process, as the drive motor 141 drives the fixture disk 144 to rotate the material disk 18, the toothed sleeve 22 on the surface of the connecting rod 182 on the material disk 18 rotates synchronously with the material disk 18. When the lens fixed on the fixing ring 183 at the end of the connecting rod 182 is tested, the connecting rod 182, having completed the test, rotates to the rear of the fixture disk 144. During this process, the toothed sleeve 22 on the connecting rod 182 meshes with the rack 23 at the upper end of the fixing cylinder 21, driving the connecting rod 182 to rotate, thereby changing the tilt angle of the lens inside the fixing ring 183 at the end of the connecting rod 182. This continues until the material disk 18 rotates 360 degrees, at which point all the connecting rods 182 on the material disk 18 rotate. Then, the material disk 182 is driven to rotate again. 8. A second rotation is performed to inspect the lens from another tilt angle. This avoids the possibility of missing defects such as oblique scratches, edge chipping, or localized coating defects under a single-angle inspection, thus improving the accuracy of the inspection. At the same time, since the length of the rack 23 is one-third of the circumference of the sleeve 22, when the sleeve 22 meshes with the rack 23, it drives the sleeve 22 to rotate the connecting rod 182 by one-third of a turn, thereby driving the lens to rotate 60 degrees. After the material tray 18 rotates one revolution, it is driven to rotate again, causing the lens to rotate to 120 degrees. This process is repeated to achieve multi-angle inspection of the lens at 0 degrees, 60 degrees, 120 degrees, 180 degrees, 240 degrees, and 300 degrees, further improving the accuracy of lens inspection.

[0051] like Figures 5 to 8 As shown, the material tray 18 is equipped with a dust removal assembly 30 inside. The dust removal assembly 30 includes a fixed seat 37 fixedly connected inside the connecting cylinder 181, and a fixed rod 31 fixedly connected to the circumferential side of the fixed seat 37. A piston cylinder 32 is movably connected inside the connecting rod 182. The fixed rod 31 passes through the inside of the piston cylinder 32 and is fixedly connected to a connecting plate 33. A first spring 34 is fixedly connected between the connecting plate 33 and the piston cylinder 32. A guide block 35 is fixedly connected to the outside of the piston cylinder 32. A guide groove 36 adapted to the guide block 35 is opened on the inner wall of the connecting rod 182. A limit strip 38 is fixedly connected to the surface of the fixed rod 31.

[0052] The guide grooves 36 are arranged in three groups at equal intervals, and each guide groove 36 is composed of an inclined groove and a vertical groove connected together. The elastic force of the first spring 34 is greater than the sliding friction between the piston cylinder 32 and the connecting rod 182. The end of the connecting rod 182 is open and connected to the fixing ring 183.

[0053] It should be noted that during the testing process, as the connecting rod 182 rotates, the connecting rod 182 and the piston cylinder 32 rotate relative to each other. This causes the guide block 35 on the surface of the piston cylinder 32 to slide along the guide groove 36 on the inner wall of the connecting rod 182. Since the fixed rod 31 is fixedly connected to the fixed seat 37, and the surface of the fixed rod 31 is provided with a limiting strip 38, the piston cylinder 32 is restricted by the limiting strip 38 and cannot rotate. This causes the guide groove 36 to rotate with the connecting rod 182. The guide block 35 drives the piston cylinder 32 to make a horizontal displacement inside the connecting rod 182 and move it closer to the fixed seat 37. During the displacement of the piston cylinder 32, the first spring is pulled. When the spring 34 unfolds, and because the guide groove 36 is composed of a sloping groove and a vertical groove connected together, when the guide block 35 moves from the sloping groove to the inside of the vertical groove, the first spring 34 will pull the piston cylinder 32 to reset by sliding the guide block 35 inside the vertical groove. When the piston cylinder 32 is displaced, it can draw external air into the inside of the connecting rod 182. When the piston cylinder 32 is reset, it will quickly squeeze the air inside the connecting rod 182 out, so that the air will be quickly ejected from the opening at the end of the connecting rod 182. The resulting jet airflow can blow away the floating dust on the lens surface, thereby ensuring the cleanliness of the lens surface and preventing floating dust from adhering to the lens surface and affecting the accuracy of the lens appearance inspection.

[0054] like Figure 4 and Figure 9 As shown, the bottom of the lamp tube 173 is provided with a supplementary light angle adjustment component 40. The supplementary light angle adjustment component 40 includes a toothed ring 42 rotatably connected to the bottom of the lamp tube 173. The top of the toothed ring 42 is provided with a groove 43, and an airbag ring 44 is fixedly connected inside the groove 43. The inside of the lamp tube 173 is provided with a movable groove 45 that is narrow inside and wide outside. The supplementary light 19 is placed inside the movable groove 45. One end of the supplementary light 19 located inside the movable groove 45 is rotatably connected to a lifting rod 47, and a second spring 46 is fixedly connected between the top of the lifting rod 47 and the movable groove 45. The airbag ring 44 is divided into multiple sacs with narrow channels between adjacent sacs. The elastic force of the second spring 46 is greater than the weight of the lifting rod 47. A toothed block 41 that meshes with the toothed ring 42 is fixedly connected to the outside of the pressure block 166.

[0055] It should be noted that during the testing process, the rotation of the fixture disc 144 and the material disc 18 will cause the pressure block 166 to rotate synchronously. When the pressure block 166 rotates, the toothed block 41 on its surface meshes with the toothed ring 42 at the bottom of the lamp tube 173, thereby causing the toothed ring 42 to rotate. After the toothed ring 42 rotates, the lifting rod 47 inside the lamp tube 173 moves to the upper end of one of the bladders in the airbag ring 44. At this time, the bladder is in an inflated state, pushing the lifting rod 47 to rise to the highest point. After the lifting rod 47 rises, it pushes the supplementary light 19 to rotate inside the movable groove 45, so that the supplementary light 19 shines downward. After the initial injection, the second spring 46 applies force to the lifting rod 47, causing the lifting rod 47 to compress the capsule, squeezing the gas in the capsule into adjacent capsules. During this process, the compressed capsules gradually deflate, causing the lifting rod 47 to gradually move downwards, thereby driving the supplementary light 19 to rotate and changing the illumination angle of the supplementary light 19. By adjusting the angle of the supplementary light 19, the appearance of the lens can be inspected under different illumination angles, thus avoiding the difficulty in identifying lens surface defects due to reflected light coverage caused by single-angle illumination, and greatly improving the accuracy of lens surface defect detection.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
