Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a detection device for optical lens coating. Background Art

[0002] Optical lens coating is a technology that coats the surface of a lens with a thin film to improve its optical performance. These films are usually composed of oxides, metals or rare earth materials and are used to enhance the transmission, reflection or polarization properties of the lens. Optical lens coating is designed to improve the performance of the lens at specific incident and polarization angles. By using appropriate optical film layers, the reflectivity of the lens surface can be reduced, the transmittance can be increased, and the optical system can transmit light more efficiently. In order to ensure the performance of the optical lens, a detection device is usually used to detect the lens after coating.

[0003] After searching, the utility model with announcement number CN214668346U discloses a detection device for optical lens coating, including a frame, a motor is connected to the top of the frame, the output end of the motor is downward and connected to a torque transmission cylinder, the torque transmission cylinder is slidably connected to a counterweight cylinder, a friction device is connected below the counterweight cylinder, and a clamping mechanism and a fixing mechanism are connected above the frame base; the base of the frame is provided with a T-slot; a square hole is provided in the center of the torque transmission cylinder; the counterweight cylinder is a hollow cylinder with an opening at one end, a rotating shaft that can match the square hole is provided in the center of the counterweight cylinder, a weight is connected inside the counterweight cylinder, and a mounting rod is provided at the other end of the counterweight cylinder; the friction device is cylindrical, and steel wool is connected below the friction device; the clamping mechanism is provided with a slider that can match the T-slot, a concave tube is connected above the slider, a plurality of springs are connected above the inner wall of the concave tube, and the spring is fixedly connected to a pressure plate, so that when the lens is subjected to friction detection, not only the detection efficiency can be improved, but also the accuracy of the friction detection can be increased.

[0004] Regarding the above scheme, the applicant believes that although the above scheme can clamp the head lens through the spring, and limit the fixing mechanism and the clamping mechanism through bolts to achieve the fixation and limitation of the lens, when the staff needs to inspect multiple lenses of different sizes, they need to frequently disassemble and install the bolts, which makes it not only troublesome and cumbersome for the staff to clamp and limit the lens, but also reduces the efficiency of lens inspection due to long-term installation and disassembly. Utility Model Content

[0005] The purpose of this application is to solve the problem that when workers need to inspect multiple lenses of different sizes, they need to frequently disassemble and install bolts, thereby reducing the efficiency of lens inspection. This application provides an inspection device for optical lens coating.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A detection device for optical lens coating, comprising a working plate, a fixing frame fixedly connected to the outer side of the working plate, a servo motor fixedly connected to the upper side of the fixing frame, an output shaft of the servo motor passing through the fixing frame, a mounting groove opened on the upper side of the working plate, a clamping mechanism and an auxiliary mechanism are arranged on the upper side of the working plate, two of each of the clamping mechanism and the auxiliary mechanism are arranged, and a friction mechanism is arranged on the lower side of the servo motor.

[0008] Furthermore, the clamping mechanism includes a bidirectional screw, a first threaded block, a second threaded block, a rotating rod, and a first clamping block. Two rotating rods are provided. The bidirectional screw is rotatably connected to the inside of the mounting groove. The first threaded block and the second threaded block are both threadedly connected to the outside of the bidirectional screw, and the first threaded block and the second threaded block are both slidably connected to the inside of the mounting groove. The two rotating rods are respectively rotatably connected to the upper sides of the first threaded block and the second threaded block, and the first clamping block is rotatably connected to one side of the two rotating rods.

[0009] By adopting the above technical solution, the working plate can install and connect the bidirectional screw through the installation groove, so that the bidirectional screw can rotate smoothly inside the working plate, and the threads on both sides of the bidirectional screw are opposite. At the same time, the working plate can also cooperate with the bidirectional screw to realize the connection between the first thread block and the second thread block.

[0010] Furthermore, the auxiliary mechanism includes a moving block, a connecting plate, a first one-way screw and a second clamping plate, the moving block is threadedly connected to the outside of the bidirectional screw, and the moving block is slidably connected to the inside of the mounting groove, the connecting plate is fixedly connected to the upper side of the moving block, the first one-way screw is threadedly connected to the inner side of the connecting plate, and the second clamping plate is fixedly connected to one end of the first one-way screw.

[0011] By adopting the above technical solution, the bidirectional screw can also connect the moving block, and the working plate can also limit the moving block, so that the moving block can move following the rotation of the bidirectional screw.

[0012] Furthermore, the friction mechanism includes a fixed rod, a sleeve, a connecting tube and steel wool, the fixed rod is fixedly connected to the output shaft of the servo motor through a coupling, the sleeve is slidably connected to the outside of the fixed rod, the connecting tube is slidably connected to the outside of the sleeve, and the steel wool is fixedly connected to the lower side of the connecting tube.

[0013] By adopting the above technical solution, the fixing rod can be connected to the connecting pipe through the sleeve, and the connecting pipe can install and fix the steel wool, so that the fixing rod can be connected to the servo motor through itself.

[0014] Furthermore, a fixed block is fixedly connected to the outer side of the sleeve, a second one-way screw is rotatably connected to the upper side of the connecting pipe, the second one-way screw is threadedly connected to the inside of the fixed block, a limiting block is fixedly connected to the outer side of the fixing rod, and the limiting block is arranged on the upper side of the sleeve.

[0015] By adopting the above technical solution, the connecting tube can be connected to the second one-way screw. When the second one-way screw rotates, it can smoothly drive the connecting tube to move downward, thereby realizing the downward pressure when rubbing the lens, and the limit block can limit the sleeve.

[0016] Furthermore, one end of the two bidirectional screws is fixedly connected to an extension rod, the two extension rods pass through the working plate, and the two extension rods are rotationally connected to the working plate, and the outer sides of the two extension rods are transmission-connected with belts.

[0017] By adopting the above technical solution and setting the belt, the staff only needs to rotate a single extension rod to realize the rotation of the two bidirectional screws, which not only makes the rotation of the two bidirectional screws more synchronous, but also makes the rotation of the two bidirectional screws more convenient and simple.

[0018] Furthermore, a rubber limiting layer is fixedly connected to the upper side of the working plate, and the rubber limiting layer is arranged directly below the connecting pipe.

[0019] By adopting the above technical solution, the provision of the rubber limiting layer can not only effectively increase the friction between the lens and the working plate, but also reduce the possibility of the lens being worn due to contact with the working plate.

[0020] Furthermore, a first rubber protective layer is fixedly connected to one side of the first clamping block, and a second rubber protective layer is fixedly connected to one side of the second clamping plate.

[0021] By adopting the above technical solution, the first rubber protective layer can reduce the wear on the edge of the lens caused by the first clamping block when clamping the lens, and can also increase the friction between the first clamping block and the lens, thereby increasing the stability of the lens when clamping.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. In the present application, the first threaded block and the second threaded block can realize the connection of the two rotating rods, and the rotating rod can be connected to the first clamping block, so that when the first threaded block and the second threaded block move in opposite directions, the first clamping block can be smoothly pushed by the two rotating rods, and after the first clamping block is pushed to a certain distance, the lens can be clamped and limited, so that the basic clamping of the lens can be achieved by rotating a single extension rod, and the stable limitation of the lens can be increased by rotating the first one-way screw, and the rotation of the single extension rod and the first one-way screw can greatly increase the convenience of limiting the lens, thereby improving the efficiency of optical lens detection.

[0024] 2. The limit block in the present application can limit the sleeve, so that when the second one-way screw is rotating, it can smoothly drive the connecting pipe to move downward, but it is not easy to drive the sleeve to move upward. At the same time, the setting of the fixed block and the second one-way screw makes it convenient and simple for the staff to replace the connecting pipe and steel wool when they need to.

The moving block 71 is threadedly connected to the outside of the bidirectional screw 51, and the moving block 71 is slidably connected to the inside of the mounting groove 4.

[0037] Reference Figure 1 and Figure 4 The friction mechanism 6 includes a fixed rod 61, a sleeve 62, a connecting tube 63 and steel wool 64. The fixed rod 61 is fixedly connected to the output shaft of the servo motor 3 through a coupling, the sleeve 62 is slidably connected to the outer side of the fixed rod 61, the connecting tube 63 is slidably connected to the outer side of the sleeve 62, and the steel wool 64 is fixedly connected to the lower side of the connecting tube 63. More specifically, the fixed rod 61 can be connected to the connecting tube 63 through the sleeve 62, and the connecting tube 63 can install and fix the steel wool 64, so that the fixed rod 61 can smoothly drive the sleeve 62, the connecting tube 63 and the steel wool 64 to rotate together through the connection between itself and the servo motor 3 when the servo motor 3 is operating, and the steel wool 64 can smoothly rub the lens placed on the upper side of the working plate 1 when rotating, thereby realizing the detection of the lens.

[0038] Reference Figure 4 and Figure 5 The outer side of the sleeve 62 is fixedly connected with a fixing block 8, and the upper side of the connecting tube 63 is rotatably connected with a second one-way screw 9, which is threadedly connected to the inside of the fixing block 8.

More specifically, the sleeve 62 can be installed on the fixing block 8, and the connecting tube 63 can be connected to the second one-way screw 9. When the second one-way screw 9 rotates, it can smoothly drive the connecting tube 63 to move downward, thereby realizing the downward pressure when rubbing the lens, and the limiting block 10 can limit the sleeve 62, so that when the second one-way screw 9 rotates, it can smoothly drive the connecting tube 63 to move downward, but it is not easy to drive the sleeve 62 to move upward.

[0039] Reference Figure 2 One end of the two bidirectional screw rods 51 is fixedly connected with an extension rod 11, and the two extension rods 11 both penetrate the working plate 1, and the two extension rods 11 are rotatably connected to the working plate 1, and the outer sides of the two extension rods 11 are transmission-connected with a belt 12. More specifically, the setting of the extension rod 11 can facilitate the staff to rotate the bidirectional screw rod 51, and the setting of the belt 12 enables the staff to rotate the two bidirectional screw rods 51 only by rotating a single extension rod 11, which can not only make the rotation of the two bidirectional screw rods 51 more synchronous, but also make the rotation of the two bidirectional screw rods 51 more convenient and simple.

[0040] Reference Figure 2A rubber limiting layer 13 is fixedly connected to the upper side of the working plate 1, and the rubber limiting layer 13 is arranged directly below the connecting tube 63. More specifically, the setting of the rubber limiting layer 13 can not only effectively increase the friction between the lens and the working plate 1, but also reduce the possibility of the lens being worn due to contact with the working plate 1.

[0041] Reference Figure 2 A first rubber protective layer 14 is fixedly connected to one side of the first clamping block 55, and a second rubber protective layer 15 is fixedly connected to one side of the second clamping plate 74. More specifically, the first rubber protective layer 14 can reduce the wear on the edge of the lens caused by the first clamping block 55 when clamping the lens, and can also increase the friction between the first clamping block 55 and the lens, thereby increasing the stability of the lens when clamping. The second rubber protective layer 15 has a similar function to the first rubber protective layer 14, and can increase the stability of the second clamping plate 74 when clamping the lens and the protectiveness of the lens when clamping.

[0042] Working principle: When the device is in use, the staff can place the lens to be inspected on the upper side of the rubber limiting layer 13, and rotate one of the extension rods 11 after placement. When one of the extension rods 11 rotates, it can drive the other extension rod 11 to rotate together through the belt 12, and the rotation of the extension rod 11 can smoothly drive the bidirectional screw 51 to rotate. When the bidirectional screw 51 rotates, it will smoothly drive the first threaded block 52 and the second threaded block 53 to move in opposite directions. When the first threaded block 52 and the second threaded block 53 move, they can smoothly push the first clamping block 55 through the rotating rod 54 to realize the movement of the first clamping block 55. After the first clamping block 55 moves to a certain distance, it can realize the preliminary clamping of the lens.

[0043] When the bidirectional screw 51 rotates, it can also smoothly drive the moving block 71 and the second clamping plate 74 to move. After the first clamping block 55 clamps the lens, the staff can rotate the first one-way screw 73. The rotation of the first one-way screw 73 will smoothly drive the second clamping plate 74 to move. After the second clamping plate 74 moves to a certain distance, it can further fix and clamp the lens, thereby limiting the position of the lens.

[0044] After that, the staff can rotate the second one-way screw 9, and the steel wool 64 can smoothly contact the lens through the rotation of the second one-way screw 9, and start the servo motor 3 after completing the above operations. The servo motor 3 will drive the connecting tube 63 and the steel wool 64 to rotate through its own operation, and the friction and detection of the lens are realized through the rotation of the steel wool 64. This can solve the problem that when the staff needs to detect multiple lenses of different sizes, they need to frequently disassemble and install bolts, which makes it troublesome and cumbersome for the staff to clamp and limit the lens, and the efficiency of lens detection is reduced due to long-term installation and disassembly.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
