[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] An optical glass refractive index detection device provided by some embodiments of the present utility model will be described below in conjunction with the accompanying drawings.
[0024] Embodiment 1:
[0025] Combination Figure 1-Figure 4 As shown, the utility model provides an optical glass refractive index detection device, including a body 100 as a carrier of the entire device, glass is placed on the bottom wall of the body 100, an irradiation lamp 101 is provided on one side of the body 100, and a receiver 102 for receiving reflected light is installed on the other side of the body 100, and an adjustment mechanism 200 for detecting the refractive index of the glass in different directions is provided in the body 100. The optical element with specific optical properties can better design and customize the optical element that meets specific requirements by understanding the refractive index of the material in different directions.
[0026] The adjustment mechanism 200 includes a connecting frame 203 for driving the irradiation lamp 101 to translate. A driving component for adjusting the angle of the irradiation lamp 101 is provided on the load-bearing frame 204. After the driving component adjusts the angle of the irradiation lamp 101, the irradiation point of the irradiation lamp 101 will change. The connecting frame 203 moves the adjusted irradiation lamp 101 so that the irradiation point of the irradiation lamp 101 is always at the center point without deviation. The refractive index of the same point of the glass at different irradiation angles can be obtained, thereby further improving the accuracy and comprehensiveness of the detection.
[0027] Specifically, the driving assembly includes a transmission shaft 206 rotatably mounted on the load-bearing frame 204, a connecting sleeve 205 is fixedly connected to the transmission shaft 206, the connecting sleeve 205 is sleeved on the outside of the irradiation lamp 101, a rack 210 is fixedly connected to the body 100, and a gear 209 meshing with the rack 210 is fixedly connected to the end of the transmission shaft 206. When the connecting frame 203 moves, it drives the transmission shaft 206 to move. Since the gear 209 is meshed with the rack 210, the transmission shaft 206 will rotate during the movement, and then the angle of the irradiation lamp 101 can be changed. The irradiation angle can be changed while moving to ensure that the irradiation point will not be offset.
[0028] Furthermore, a motor 201 is fixedly installed in the body 100, and a screw 202 is fixedly connected to the output end of the motor 201. A connecting frame 203 is threadedly connected to the screw 202, and a load frame 204 is fixedly connected to the connecting frame 203. The end of the connecting frame 203 is slidably connected to the top wall of the body 100 through a slide groove. The motor 201 is started to drive the screw 202 to rotate, and the rotation of the screw 202 drives the connecting frame 203 to move. The irradiation lamp 101 moves with the connecting frame 203. By using the motor 201 as a single power source, the refractive index detection at different angles at the same point on the glass can be realized, which can reduce the cost of detection.
[0029] According to the embodiment, the irradiation lamp 101 emits a beam of light, which enters the sample in the body 100, and the adjustment mechanism 200 can check the incident angle of the light. Due to the different refractive indices of the samples, the light will be refracted in the sample, and the refracted light will be received by the receiver 102. The receiver 102 will measure the angle of the refracted light according to the position of the light. Through the measured angle data, combined with Snell's law, that is, the relationship between the incident angle and the refraction angle:
[0030] n1*sin(θ1)=n2*sin(θ2);
[0031] Among them, n1 and n2 are the refractive indices of the two media, θ1 and θ2 are the incident angle and refraction angle, respectively. The refractive index of the sample is calculated.
[0032] Embodiment 2:
[0033] Combination Figure 1 and Figure 3 As shown, on the basis of the first embodiment, an electromagnetic coil 207 is fixedly connected to the load frame 204, and an electromagnetic block 208 corresponding to the electromagnetic coil 207 is fixedly connected to the end of the transmission shaft 206. Since the electromagnetic block 208 rotates with the transmission shaft 206, the electromagnetic coil 207 can detect the position of the electromagnetic block 208, and then the irradiation angle of the irradiation lamp 101 can be obtained. The electromagnetic coil 207 can send the angle of the irradiation lamp 101 to the system on the body 100, so that the system can detect the refractive index of the glass.
[0034] Specifically, an angle ruler 105 for checking the angle of the light refraction line is installed in the middle of the inner wall of the body 100. The angle ruler 105 can be used to manually check the incident angle and the refraction angle and calculate the refractive index, which can be compared with the machine calculation to further improve the accuracy of the detection.
[0035] Furthermore, a control panel 103 is fixedly mounted on the body 100, and a door 104 is hinged on the body 100. The staff can control the components in the body 100 through the control panel 103 and view the detected data. When the staff needs to detect other points on the glass, they can move the position of the glass.
[0036] It can be known from the above embodiments that: the staff puts the glass into the body 100, and then the irradiation lamp 101 emits a beam of light, the light is injected into the glass in the body 100, and the electromagnetic coil 207 sends data to the system, and the system obtains the incident angle of the light. Due to the different refractive indices of the samples, the light will be refracted in the samples, and the refracted light will be received by the receiver 102. The receiver 102 will measure the angle of the refracted light through the position of the light, and calculate the refractive index through the measured angle data.
[0037] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
