Description

Technical Field

[0001] This utility model belongs to the field of lens testing technology, and specifically relates to a lens focusing testing device. Background Technology

[0002] Optical lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be measured with optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. Only qualified glass blocks are heated and forged to form optical lens blanks.

[0003] However, traditional lens focusing inspection devices mostly have only a single illumination component. When different standards of inspection are required, different specifications of illumination plates need to be temporarily replaced, which is quite inconvenient. Moreover, traditional inspection devices are difficult to inspect multiple lenses at the same time during actual inspection, which further leads to low inspection efficiency.

[0004] Therefore, those skilled in the art have provided a lens focusing detection device to solve the problems mentioned in the background art. Utility Model Content

[0008] In a preferred embodiment, a protective frame is installed on the fixed platform, and the electric push rod is located inside the protective frame.

[0009] In a preferred embodiment, a light-concentrating cover is provided at the opening at the bottom of the mounting frame, and the light-concentrating cover is generally funnel-shaped.

[0010] In a preferred embodiment, the clamping mechanism includes a placement slot, and the placement plate is provided with a plurality of placement slots, which are distributed in a rectangular array.

[0014] This utility model, by setting up a fixed platform, a mounting frame, a slider, an electric push rod, a motor, a turntable, and light panels, allows the user to first connect the electric push rod on the fixed platform to power during lens focusing tests. The electric push rod then pushes the mounting frame, which moves within the fixed platform via the slider until it is adjusted to a suitable height. Next, the motor is connected to power, causing the turntable to rotate. The turntable then rotates multiple light panels on it. Depending on the actual situation, the required light panels can be rotated and adjusted to the opening on the mounting frame, making it convenient to replace different specifications of light panels to meet different light focusing test standards, thus making the operation more convenient.

[0015] This invention, by setting up a placement plate, placement slots, a first clamping frame, a second clamping frame, and springs, allows the lenses to be tested to be placed into different placement slots on the placement plate before actual testing. Then, the first and second clamping frames can be pushed in opposite directions, and the corresponding springs will contract simultaneously until the lens to be tested is placed between the first and second clamping frames. Then, the pressure on the first and second clamping frames can be released, and under the action of the springs, the first and second clamping frames can clamp and limit the lens to be tested, thus facilitating the simultaneous placement and testing of multiple lenses.

[0025] Please see Figure 1-6 This utility model provides a lens focusing detection device, including a fixed platform 1, on which multiple support rods 2 are fixedly connected. A pushing mechanism 3 is provided on the fixed platform 1, and the pushing mechanism 3 includes a mounting frame 301. The mounting frame 301 is located inside the fixed platform 1. An electric push rod 304 is provided on the fixed platform 1. An illumination mechanism 4 is located inside the mounting frame 301. The illumination mechanism 4 includes a turntable 402. The turntable 402 is rotatably connected inside the mounting frame 301. Multiple lamp plates 403 are installed on the turntable 402. A motor 401 is located inside the mounting frame 301. The transmission end of the motor 401 is connected to the turntable 402. A placement plate 5 is provided between the multiple support rods 2. A clamping mechanism 6 is provided on the placement plate 5.

[0026] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a slider 302 is fixedly connected to each side of the mounting frame 301. The slider 302 is slidably connected to the inside of the fixed platform 1. The slider 302 facilitates the movement of the mounting frame 301.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, a protective frame 303 is installed on the fixed platform 1, and an electric push rod 304 is located inside the protective frame 303. The protective frame 303 facilitates the placement of the electric push rod 304.

[0028] Specifically, such as Figure 2 As shown, a condenser 305 is provided at the opening at the bottom of the mounting frame 301, and the condenser 305 is shaped like a trumpet. The condenser 305 is used to better concentrate the detection light source.

[0029] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, the clamping mechanism 6 includes a placement groove 601. The placement plate 5 has multiple placement grooves 601 arranged in a rectangular array. A first clamping frame 602 and a second clamping frame 603 are slidably connected within each placement groove 601. A spring 605 is fixedly connected to each of the first clamping frame 602 and the second clamping frame 603, and the spring 605 is fixedly connected to the inner wall of the placement plate 5. A limiting rod 604 is fixedly connected to each of the first clamping frame 602 and the second clamping frame 603, and the limiting rod 604 is slidably connected inside the placement plate 5. Furthermore, the spring 605 is wound around the limiting rod 604. In use, the first clamping frame 602 and the second clamping frame 603 can be pushed in opposite directions, and the corresponding spring 605 will contract simultaneously. The limiting rod 604 will limit and guide the spring 605 until the lens to be tested enters between the first clamping frame 602 and the second clamping frame 603. Then, the pressure on the first clamping frame 602 and the second clamping frame 603 can be released. Under the action of the spring 605, the first clamping frame 602 and the second clamping frame 603 can clamp and limit the lens to be tested.

[0030] The working principle and usage process of this utility model are as follows: Before actual testing, the lenses to be tested can be placed into different placement slots 601 on the placement plate 5. Then, the first clamping frame 602 and the second clamping frame 603 can be pushed in opposite directions, and the corresponding springs 605 will contract at the same time until the lens to be tested enters between the first clamping frame 602 and the second clamping frame 603. Then, the pressure on the first clamping frame 602 and the second clamping frame 603 can be released. Under the action of the spring 605, the first clamping frame 602 and the second clamping frame 603 can clamp and limit the lens to be tested, thereby facilitating the simultaneous placement and testing of multiple lenses.

[0031] Then, when performing focus testing on the lens, the user can first turn on the power to the electric push rod 304 on the fixed stage 1. The electric push rod 304 will push the mounting frame 301, and the mounting frame 301 will move inside the fixed stage 1 through the slider 302 until the mounting frame 301 is adjusted to a suitable height. Next, the power to the motor 401 will be turned on, and the rotation of the motor 401 will drive the turntable 402 to rotate together. The rotation of the turntable 402 will drive the multiple lamp plates 403 on it to rotate together. According to the actual situation, the corresponding lamp plate 403 can be rotated and adjusted to the opening on the mounting frame 301, so as to facilitate the replacement of different specifications of illumination plates according to the actual situation to meet different illumination focus testing standards, making the operation more convenient.
