Description

Technical Field

[0001] This utility model relates to the field of stress detection technology, and in particular to a glass stress distribution detection device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary raw materials. It is widely used in buildings to insulate against wind and allow light to pass through, and is a mixture.

[0003] Glass needs to undergo internal stress testing using a glass stress meter to determine whether the stress distribution of the glass meets the standards. The glass stress meter mainly consists of components such as the main body, objective lens, and analyzer.

[0004] Existing glass stress meters require operators to place the glass directly on the testing platform when performing polarized stress testing. This exposes the glass to the external environment, where beams of light randomly strike the glass, affecting the accuracy of stress distribution testing. Therefore, a glass stress distribution testing device is proposed to address this issue. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a glass stress distribution detection device, which aims to improve the problem that when glass is exposed to the external environment, the beams of light from the external environment may irradiate randomly, and some may directly irradiate the glass to be tested, thus affecting the effectiveness of glass stress distribution detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass stress distribution detection device, comprising a glass stress meter body, a stage for carrying an objective lens on the top of the glass stress meter body, an adjustment mechanism on one side of the top of the glass stress meter body, an analyzer connected to the adjustment mechanism, a light-shielding mechanism on the top of the glass stress meter body, the light-shielding mechanism covering the outside of the stage for carrying an objective lens, and a placement mechanism on the top of the stage for carrying an objective lens.

[0007] The light-shielding mechanism includes a light-shielding cover, which is connected to the top of the glass stress meter body via a mounting assembly. The light-shielding cover is located outside the objective lens stage, and a fixing assembly is provided outside the objective lens stage.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes a mounting block, which is fixedly connected to the top of the glass stress meter body. The top of the mounting block has a mounting groove, and the bottom of the light shield is inserted into the inner wall of the mounting groove.

[0010] As a further description of the above technical solution:

[0011] The fixing component includes elastic clips and slots. A plurality of elastic clips are evenly distributed on the outer side of the light shield, and a plurality of slots are evenly opened on the outer side of the mounting block.

[0012] As a further description of the above technical solution:

[0013] One end of the elastic clip engages with the inner wall of the opposite side slot.

[0014] As a further description of the above technical solution:

[0015] The adjustment mechanism includes a positioning cylinder, which is fixedly connected to the top through hole of the glass stress meter body. An adjustment rod is slidably connected to the inner wall of the positioning cylinder, and the top of the adjustment rod is fixedly connected to the outer side of the analyzer.

[0016] As a further description of the above technical solution:

[0017] The adjusting rod is connected to the positioning cylinder via a positioning screw.

[0018] As a further description of the above technical solution:

[0019] The placement mechanism includes a placement plate, the bottom of which is provided with a limiting component, and the placement plate is connected to the top of the objective stage through the limiting component.

[0020] As a further description of the above technical solution:

[0021] The limiting assembly includes limiting rods and limiting grooves. The tops of the multiple limiting rods are fixedly connected to the bottom of the placement plate, and the multiple limiting grooves are all opened on the top of the objective stage. The bottoms of the multiple limiting rods are respectively inserted into the inner wall of the limiting groove on the opposite side.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the light shield is inserted into the mounting groove on the mounting block. Multiple elastic clips evenly distributed on the outside of the light shield engage with the clips on the outside of the mounting block, so that the light shield is firmly placed on the outside of the objective lens stage, preventing external light from entering and providing a relatively dark environment for detection, reducing the interference of stray light on the detection results. The adjustment mechanism allows the detection light to shine on the glass at the optimal angle, thereby improving the detection accuracy.

[0024] 2. In this utility model, the limiting rod on the placement plate is inserted into the corresponding limiting groove to fix the placement plate. Then the glass is placed on the placement plate, thereby avoiding wear between the mirror and the glass on the objective lens stage. This extends the service life of the objective lens stage and reduces the cost of device replacement and maintenance. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a glass stress distribution detection device, comprising a glass stress meter body 1, a stage 2 mounted on the top of the glass stress meter body 1, and an analyzer 6 connected to an adjustment mechanism 3. The glass stress meter body 1, stage 2, and analyzer 6 are all prior art and will not be described in detail here. A light-shielding mechanism 4 is mounted on the top of the glass stress meter body 1, covering the outside of the stage 2. The light-shielding mechanism 4 effectively blocks external light from entering the detection area, providing a relatively stable and dark environment for detection, thus reducing interference from stray light and ensuring the reliability of the detection data. The light-shielding mechanism 4 includes a light-shielding cover 403, which is connected to the top of the glass stress meter body 1 via a mounting assembly. The light-shielding cover 403 is located outside the stage 2. The light-shielding cover 403 has a simple and practical design, and its connection to the glass stress meter body 1 via the mounting assembly facilitates installation and disassembly, as well as maintenance and cleaning. Meanwhile, the light shield 403 is located outside the stage 2, which can completely block external light and provide a good light shielding effect for the inspection.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The mounting assembly includes a mounting block 401, which is fixedly connected to the top of the glass stress meter body 1, providing a stable foundation for the installation of the light shield 403. A mounting groove 402 is formed on the top of the mounting block 401, providing a clear positioning for the installation of the light shield 403. The bottom of the light shield 403 is inserted into the inner wall of the mounting groove 402. This insertion-type installation method is simple and quick, facilitating the installation and removal of the light shield 403. When maintenance or replacement of the light shield 403 is required, it can be easily removed from the mounting groove 402.

[0034] Reference Figure 1 , Figure 2 and Figure 3The objective stage 2 is externally equipped with a fixing component, which provides further stability for the installation of the light shield 403 outside the objective stage 2, ensuring that the light shield 403 will not accidentally loosen or fall off during the inspection process, thereby maintaining a stable inspection environment. The fixing component includes elastic clips 404 and slots 405. Multiple elastic clips 404 are evenly distributed on the outer side of the light shield 403. The evenly distributed elastic clips 404 can fix the light shield 403 from multiple directions, making the force on the light shield 403 more uniform and improving the stability of the fixation. Multiple slots 405 are evenly opened on the outer side of the mounting block 401. The even distribution of multiple slots 405 makes it easy for the elastic clips 404 to quickly and accurately find the snap-fit ​​position. One end of the elastic clip 404 engages with the inner wall of the opposite slot 405. The snap-fit ​​operation is simple and can be completed without the use of additional tools. The elastic clip 404 can provide a certain clamping force after being inserted into the clip slot 405, ensuring that the connection between the sunshade 403 and the mounting block 401 is firm and reliable, and effectively preventing the sunshade 403 from loosening.

[0035] Reference Figure 1 and Figure 2 An adjustment mechanism 3 is provided on one side of the top of the glass stress meter body 1. The adjustment mechanism 3 includes a positioning cylinder 301, which is fixedly connected to the top through hole of the glass stress meter body 1. An adjustment rod 302 is slidably connected to the inner wall of the positioning cylinder 301. The top of the adjustment rod 302 is fixedly connected to the outer side of the analyzer 6. The adjustment rod 302 is connected to the positioning cylinder 301 through a positioning screw 303.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The top of the stage 2 is provided with a placement mechanism 5, which includes a placement plate 501. The placement plate 501 prevents the mirror and glass on the stage 2 from being worn. The bottom of the placement plate 501 is provided with a limiting component. The placement plate 501 is connected to the top of the stage 2 through the limiting component to ensure that the placement plate 501 is accurately positioned on the stage 2 and to prevent the placement plate 501 from shifting or shaking during the testing process.

[0037] Reference Figure 3 and Figure 4 The limiting assembly includes limiting rods 502 and limiting grooves 503. The tops of multiple limiting rods 502 are fixedly connected to the bottom of the placement plate 501, and multiple limiting grooves 503 are opened on the top of the stage 2. The bottoms of multiple limiting rods 502 are respectively inserted into the inner wall of the limiting groove 503 on the opposite side. The insertion and engagement of the limiting rods 502 and the limiting grooves 503 can effectively prevent the placement plate 501 from moving in the horizontal direction, ensuring that the glass is always in the correct position during the inspection process and avoiding the impact of positional deviation on the inspection results.

[0038] Working principle: First, the limiting rod 502 on the placement plate 501 is inserted into the corresponding limiting groove 503 to fix the placement plate 501. Then, the glass is placed on the placement plate 501, and the light shield 403 is inserted into the mounting groove 402 on the mounting block 401. Multiple elastic clips 404 evenly distributed on the outside of the light shield 403 engage with the slots 405 on the outside of the mounting block 401, so that the light shield 403 is firmly covered on the outside of the stage 2, preventing external light from entering and providing a relatively dark environment for detection, reducing the interference of stray light on the detection results.

[0039] Then, the position of the analyzer 6 is adjusted using the adjustment mechanism 3. The adjusting rod 302 slides on the inner wall of the positioning cylinder 301 and at the top through-hole of the glass stress meter body 1, thereby changing the height of the analyzer 6. After adjusting to the appropriate position, the adjusting rod 302 is fixed to the positioning cylinder 301 using the positioning screw 303 to ensure that the analyzer 6 is stable during the testing process. This ensures that the testing light shines onto the glass at the optimal angle.

[0040] Finally, the main body 1 of the glass stress meter emits specific light that shines onto the glass on the placement plate 501 on the stage 2. The light undergoes a specific polarization change after passing through the glass. The analyzer 6 analyzes the polarized light transmitted through the glass and determines the stress distribution in the glass based on the change in the polarization state of the light.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
