Description

Technical Field

[0001] This utility model relates to the field of optical lens testing technology, and in particular to an optical lens refractive index testing and calibration device. Background Technology

[0002] Optical lenses are lenses made using optical glass. Optical glass is defined as glass with specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance, and light absorption, and with uniform optical properties. Refractive index refers to the ratio of the speed of light in air to the speed of light in the material. During the production process of optical lenses, most lenses have a certain refractive index to meet different imaging effects. If the refractive index of the lens does not meet the standard, it will affect the imaging effect, so it is necessary to test its refractive index.

[0003] In existing technologies, the surface of optical lenses is usually wiped manually by staff to avoid impurities adhering to the surface of the optical lenses and affecting the test results. However, this method is relatively cumbersome and reduces the test efficiency. In response to the above problem, the literature with application number: 202322944916.X discloses an optical lens refractive index testing device, which includes a frame, on which a laser emitting device and a photosensitive plate are slidably mounted. A fixing frame is provided on the frame, located between the laser emitting device and the photosensitive plate. The fixing frame is provided with a fixing component and a wiping component. The fixing component fixes or releases the optical lens, and the wiping component wipes the opposite surfaces of the optical lens simultaneously.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: during use, the optical lens needs to be detached from its fixing component before another optical lens can be inspected, which is a cumbersome process that affects the production efficiency of optical lenses and leaves room for improvement.

[0005] Therefore, we propose an optical lens refractive index detection and calibration device to solve the problems in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an optical lens refractive index detection and calibration device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An optical lens refractive index detection and calibration device includes a base plate, a feeding mechanism, and a fixing mechanism;

[0009] A bracket is fixedly connected to the base plate, and a round tube and a control module are fixedly installed on the bracket. An optical lens is provided inside the round tube, and a feeding mechanism is provided on the base plate, which is connected to the round tube.

[0010] The feeding mechanism includes a cylinder, a frame, a first partition, a second partition, a housing, a circular plate, and a motor. The housing is fixedly installed on the base plate, and a circular plate is rotatably connected inside the housing. The circular plate has four through holes, each containing a fixing mechanism. The fixing mechanism includes a fixing plate, a clamping plate, a spring, and a pulley. The fixing plate is fixedly installed in each of the four through holes. Through the coordinated design of the circular tube, the feeding mechanism, the fixing mechanism, and the control module, not only can the refractive index of the optical lens be detected, but also the automatic feeding and unloading can be achieved. This enables automated production line inspection and processing of the optical lens, improving the inspection and processing efficiency. Moreover, the structure is simple and highly practical.

[0011] Specifically, one of the four through holes corresponds to the circular tube. A motor is fixedly installed on the base plate, and the output end of the motor is fixedly connected to the circular plate. The motor is connected to the control module. A second through hole is provided on the housing, corresponding to the first through hole. Driven by the motor, the circular plate rotates intermittently within the housing, thereby intermittently conveying the optical lens to the position corresponding to the laser emitting mechanism and the photosensitive plate, thus achieving the effect of intermittent feeding.

[0012] Specifically, a cylinder is fixedly installed on the base plate, and a frame is fixedly connected to one end of the cylinder. A partition plate 1 and a partition plate 2 are fixedly installed on the frame. Both partition plates 1 and 2 are slidably connected to the circular tube. The four through holes 1 are adapted to the optical lens. The extension and retraction of the cylinder causes the frame to drive partition plates 1 and 2 to move back and forth. During this process, since the distance between partition plates 1 and 2 is adapted to the optical lens, the effect of intermittent feeding of the optical lens is achieved.

[0013] Specifically, an arc plate is fixedly connected to the frame. The arc plate is slidably connected to and adapted to the housing. The distance between the first partition and the second partition corresponds to the optical lens. The arc plate facilitates the clamping plate to hold and fix the optical lens, and also facilitates the pulley to roll on the inner wall of the housing.

[0014] Specifically, a clamping plate is slidably connected to the fixing plate. The clamping plate interacts with the circular plate to hold and fix the optical lens. The clamping plate and the circular plate are slidably connected to hold and fix the optical lens.

[0015] Specifically, a spring is fixedly sleeved on the clamping plate, one end of the spring is fixedly connected to the fixing plate, and a pulley is fixedly installed on one end of the clamping plate. The pulley abuts against the machine housing, and a groove is provided on the machine housing, which corresponds to the pulley. The clamping plate is restored to its original state by the action of the spring.

[0016] Specifically, the base plate is provided with a laser emitting mechanism and a photosensitive plate. The laser emitting mechanism and the photosensitive plate are each associated with one of the four through holes. The laser emitting mechanism and the photosensitive plate are both connected to the control module. Through the cooperation between the laser emitting mechanism and the photosensitive plate, the refractive index of the optical lens can be detected.

[0017] Specifically, a conveyor is provided on the base plate, and the conveying mechanism corresponds to one of the four through holes. The conveyor is connected to the control module. A groove is provided on the housing, which corresponds to the conveyor. When the optical lens moves to be opposite the conveyor, the clamping plate releases the optical lens through the action of the groove and the elastic potential energy of the spring, so that the optical lens falls onto the conveyor. Then, the optical lens is transported to the next processing step by the action of the conveyor, thereby realizing the effect of automated assembly line processing of the optical lens and improving the production efficiency of optical lenses.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The optical lens refractive index detection and calibration device of this utility model uses the extension and retraction drive of the cylinder to drive the frame to move the partition one and the partition two back and forth. During this process, since the distance between the partition one and the partition two is adapted to the optical lens, the effect of intermittent feeding of the optical lens is achieved. The circular plate is driven by the motor to rotate intermittently in the housing, thereby intermittently conveying the optical lens to the position corresponding to the laser emitting mechanism and the photosensitive plate, thus achieving the effect of intermittent feeding.

[0020] (2) An optical lens refractive index detection and calibration device of the present invention, when the cylinder extends, the frame drives the arc plate to connect with the housing, and the arc plate pushes the clamping plate to slide on the fixed plate and the circular plate through the pulley, so that the spring is stretched and the optical lens is held and fixed.

[0032] The feeding mechanism 4 includes a cylinder 41, a frame 42, a first partition 43, a second partition 44, a housing 46, a circular plate 47, and a motor 48. The housing 46 is fixedly installed on the base plate 1. The circular plate 47 is rotatably connected inside the housing 46. The circular plate 47 has four through holes, and each of the four through holes is equipped with a fixing mechanism 6. The fixing mechanism 6 includes a fixing plate 61, a clamping plate 62, a spring 63, and a pulley 64. The fixing plate 61 is fixedly installed in each of the four through holes. Through the coordinated design between the circular tube 9, the feeding mechanism 4, the fixing mechanism 6, and the control module 5, not only can the refractive index of the optical lens 7 be detected, but also the automatic feeding and unloading effects can be achieved. This enables automated production line inspection and processing of the optical lens 7, improving the inspection and processing efficiency of the optical lens 7. Moreover, the structure is simple and more practical.

[0033] In this method, one of the four through holes corresponds to the circular tube 9. A motor 48 is fixedly installed on the base plate 1. The output end of the motor 48 is fixedly connected to the circular plate 47. The motor 48 is connected to the control module 5. A second through hole is opened on the housing 46 and corresponds to the first through hole. Driven by the motor 48, the circular plate 47 rotates intermittently inside the housing 46, thereby intermittently conveying the optical lens 7 to the position corresponding to the laser emitting mechanism 2 and the photosensitive plate 8, thus achieving the effect of intermittent feeding.

[0034] In this method, a cylinder 41 is fixedly installed on the base plate 1. A frame 42 is fixedly connected to one end of the cylinder 41. A partition 43 and a partition 44 are fixedly installed on the frame 42. Both partitions 43 and 44 are slidably connected to the round tube 9. The four through holes are adapted to the optical lens 7. The extension and retraction of the cylinder 41 causes the frame 42 to drive the partitions 43 and 44 to move back and forth. During this process, since the distance between partitions 43 and 44 is adapted to the optical lens 7, the effect of intermittent feeding of the optical lens 7 is achieved.

[0035] In this method, an arc plate 45 is fixedly connected to the frame 42. The arc plate 45 is slidably connected to the housing 46 and is adapted to the housing 46. The distance between the partition 1 43 and the partition 2 44 corresponds to the optical lens 7. The arc plate 45 facilitates the clamping plate 62 to hold and fix the optical lens 7, and facilitates the pulley 64 to roll on the inner wall of the housing 46.

[0036] In this method, a clamping plate 62 is slidably connected to the fixing plate 61. The clamping plate 62 interacts with the circular plate 47 to hold and fix the optical lens 7. The clamping plate 62 and the circular plate 47 are slidably connected to hold and fix the optical lens 7.

[0037] In this method, a spring 63 is fixedly sleeved on the clamping plate 62. One end of the spring 63 is fixedly connected to the fixing plate 61. A pulley 64 is fixedly installed on one end of the clamping plate 62. The pulley 64 abuts against the machine housing 46. A groove 11 is opened on the machine housing 46. The groove 11 corresponds to the pulley 64. The clamping plate 62 is restored to its original state by the action of the spring 63.

[0038] In this method, a laser emitting mechanism 2 and a photosensitive plate 8 are provided on the base plate 1. Both the laser emitting mechanism 2 and the photosensitive plate 8 correspond to one of the four through holes. Both the laser emitting mechanism 2 and the photosensitive plate 8 are connected to the control module 5. Through the cooperation between the laser emitting mechanism 2 and the photosensitive plate 8, the refractive index of the optical lens 7 can be detected. The specific structure and working principle of the laser emitting mechanism 2 and the photosensitive plate 8 can be referred to the literature with application number: 202322944916.X. This is the prior art and will not be described in detail.

[0039] In this method, a conveyor 10 is provided on the base plate 1, and the conveying mechanism corresponds to one of the four through holes. The conveyor 10 is connected to the control module 5. A groove 11 is provided on the housing 46, which corresponds to the conveyor 10. When the optical lens 7 moves to be opposite the conveyor 10, the clamping plate 62 releases the optical lens 7 through the action of the groove 11 and the elastic potential energy of the spring 63, so that the optical lens falls on the conveyor 10. Then, the optical lens 7 is transported to the next processing step by the action of the conveyor 10, thereby realizing the effect of automated assembly line processing of the optical lens 7 and improving the production efficiency of the optical lens 7.

[0040] Working principle: During use, the control module 5 drives and controls the cylinder 41, the electric motor 48, the laser emitting mechanism 2, the photosensitive plate 8, and the conveyor 10.

[0041] The extension and retraction drive of cylinder 41 causes frame 42 to drive partition 1 43 and partition 2 44 to move back and forth. During this process, since the distance between partition 1 43 and partition 2 44 is adapted to the optical lens 7, the effect of intermittent feeding of optical lens 7 is achieved, so that optical lens 7 intermittently falls into the corresponding through hole 1.

[0042] Meanwhile, the electric motor 48 drives the circular plate 47 to rotate intermittently within the housing 46, thereby intermittently conveying the optical lens 7 to the position corresponding to the laser emitting mechanism 2 and the photosensitive plate 8, thus achieving the effect of intermittent feeding; at the same time, the cooperation between the laser emitting mechanism 2 and the photosensitive plate 8 can achieve the effect of refractive index detection of the optical lens 7.

[0043] During this process, when the cylinder 41 extends, the frame 42 drives the arc plate 45 to connect with the housing 46. At the same time, the arc plate 45 pushes the clamping plate 62 to slide on the fixed plate 61 and the circular plate 47 through the pulley 64, and the spring 63 is stretched to hold and fix the optical lens 7. Then, while the motor 48 is driven, the circular plate 47 drives the optical lens 7 to rotate synchronously through the action of the clamping plate 62, and at the same time, the pulley 64 rolls on the inner wall of the housing 46.

[0044] Subsequently, when the optical lens 7 moves to be opposite the conveyor 10, the clamp 62 releases the optical lens 7 through the action of the groove 11 and the elastic potential energy of the spring 63, so that the optical lens falls onto the conveyor 10. Then, the optical lens 7 is transported to the next processing step by the action of the conveyor 10, thereby realizing the effect of automated assembly line processing of the optical lens 7 and improving the production efficiency of the optical lens 7.

[0045] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the refractive index of the optical lens 7 be detected, but also the automatic feeding and unloading effects can be achieved, thereby realizing the automated production line detection and processing of the optical lens 7, improving the detection and processing efficiency of the optical lens 7, and the structure is simple and more practical.
