Description

Technical Field

[0001] This utility model relates to the field of Arabica detection technology, and in particular to an Arabica instrument fixture. Background Technology

[0002] In the current optical cold processing industry, when performing Arabic inspection on lenses, the lens is held flat and placed on the lens of the Arabic instrument. The lens is then illuminated by an LED light and moved back and forth, so that the image is displayed on the screen panel, showing the Arabic black spots on the lens surface.

[0003] However, this method has slight deviations when manually calibrating the focus point for each lens. It takes 1 to 3 minutes to calibrate one lens, which is too time-consuming, cumbersome, and inefficient. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide an Arabic instrument gauge.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An Arabic instrument fixture includes an Arabic instrument body, a fixture body, and an LED light fixture. The fixture body is embedded and fixed directly above the Arabic instrument body. The LED light fixture is located directly above the fixture body. A lens to be measured is placed on the top surface of the fixture body. A lens is positioned at the center of the Arabic instrument body. The fixture body is located directly above the lens. The lens, fixture body, lens to be measured, and LED light fixture are all on the same vertical axis. A display screen is electrically connected to the lens of the Arabic instrument body. The display screen is located on one side of the Arabic instrument body.

[0007] Furthermore, a circular placement groove is provided on the top surface of the main body of the inspection tool; the placement groove is a hollow groove that runs vertically through the top and bottom; the placement groove is located directly above the lens, and the circular position of the placement groove is consistent with the center position of the lens.

[0008] Furthermore, the placement groove is a groove with a smooth and flat surface.

[0009] Furthermore, the placement slot is a slot with a width equal to that of the lens to be measured and a height lower than that of the lens to be measured.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention involves embedding and fixing the instrument fixture body directly above the lens of an Arabic instrument. The lens to be measured is placed on top of the fixture body, and then the LED light above the lens is illuminated to illuminate the lens's focus point. The placement slot allows the lens to be placed more stably on the top surface of the fixture body. The lens, fixture body, lens to be measured, placement slot, and LED light are all on the same vertical axis, thereby avoiding deviations in the lens's focus point alignment, improving lens calibration accuracy, reducing measurement and calibration time, simplifying operation steps, increasing lens yield, effectively reducing scrap caused by inaccurate lens measurement, and lowering production costs. Furthermore, the Arabic instrument fixture has a simple structure and is easy to use. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Example

[0019] like Figure 1 and 2As shown, an Arabic instrument fixture is used on a testing table (not shown in the figure), comprising an Arabic instrument body 1, a fixture body 2, and an LED lamp 3; the fixture body 2 is embedded and fixed directly above the Arabic instrument body 1; the LED lamp 3 is located directly above the fixture body 2, and the LED lamp (3) is fixed on a lamp holder (not shown in the figure), which is fixed on the table behind the Arabic instrument body 1 (not shown in the figure); a lens 4 to be measured is placed on the top surface of the fixture body 2; a lens 7 is set at the center of the Arabic instrument body 1; the fixture body 2 is located directly above the lens 7; the lens 7, fixture body 2, lens 4 to be measured, and LED lamp 3 are on the same vertical axis; the lens 7 of the Arabic instrument body 1 The instrument is electrically connected to a display screen 5, which is located on one side of the Arabic instrument body 1. A circular placement slot 6 is provided on the top surface of the gauge body 2. The placement slot 6 is hollow and runs vertically through the entire structure. The placement slot 6 is located directly above the lens 7, and its circular position coincides with the center of the lens 7. This eliminates the need for cumbersome manual focusing; simply placing the lens to be measured 4 flat into the placement slot 6 completes the focusing process, preventing deviations in focus point positioning. The placement slot 6 has a smooth and flat surface, preventing wear and scratches on the lens to be measured 4. The placement slot 6 has a width equal to and a height lower than the lens to be measured 4, facilitating the insertion and removal of the lens to be measured without causing movement that could alter the focus point.

[0020] The working principle of this utility model is as follows:

[0021] First, fix the main body 2 of the inspection fixture to the top of the main body 1 of the Arabic instrument by embedding and fixing it, and fix the LED light fixture 3 to ensure that the center positions of the lens 7, the placement slot 6 and the LED light fixture 3 are consistent and on the same vertical axis. Then, place the lens 4 to be measured in the placement slot 6, and then turn on the LED light fixture 3 so that the LED light fixture 3 illuminates the lens 4 to be measured and the focus point is on the lens 7. The lens 7 and the display 5 are electrically connected so that the Arabic black spot phenomenon on the surface of the lens 4 to be measured is displayed on the display screen 5.

[0022] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
