Description

Technical Field

[0001] This utility model relates to a test fixture for detecting the heating uniformity of ITO glass, specifically a standard test fixture for detecting the heating uniformity of ITO glass. Background Technology

[0002] ITO (Indium Tin Oxide Conductive Glass) is a high-tech product in which a layer of indium tin oxide (ITO) conductive film is deposited on a glass substrate through methods such as physical vapor deposition or magnetron sputtering. This type of glass combines the transparency of glass with the conductivity of ITO film, and has high conductivity, high transparency (visible light transmittance can typically reach over 90%), corrosion resistance, and good processability.

[0003] ITO glass is often used in applications requiring uniform heating; therefore, heating uniformity is one of the key quality indicators for ITO glass. Uneven heating of ITO glass can lead to localized overheating or underheating, affecting the normal operation of the equipment. Furthermore, it can damage the ITO film or accelerate its aging, thus impacting the lifespan of the ITO glass.

[0004] However, in existing technologies, when testing the heating uniformity of ITO glass, multiple resistors are usually arranged on the surface of the TO glass as detection points, and then the heating uniformity of the ITO glass is evaluated by detecting the resistance values ​​of different areas.

[0005] However, in the existing technology, after each ITO glass is tested and a new ITO glass is placed for a new round of testing, the test points on the ITO glass need to be rearranged, which results in a long testing time and affects the testing speed and efficiency.

[0006] Furthermore, existing technologies typically involve manually arranging measurement points, which makes it difficult to ensure consistency in each measurement, leading to reduced consistency in test data and consequently affecting the accuracy of the test data. Utility Model Content

[0007] In order to solve the problems in related technologies, this utility model provides a standard testing fixture for detecting the heating uniformity of ITO glass. This device solves the problems of long testing time and the impact on testing accuracy caused by differences in the position of test points due to human operation.

[0008] To solve the above problems, the following technical solutions are provided:

[0009] A standard test fixture for detecting the heating uniformity of ITO glass is characterized by comprising a lower mold and an upper mold. The lower mold has recesses for fixing the ITO glass, and the upper mold has multiple test pieces with intervals between adjacent test pieces. When the lower mold and the upper mold are closed, all test pieces are in contact with the ITO glass.

[0010] With the above technical solution and the setting of multiple detection components, each time the heating uniformity is tested, it is only necessary to place the ITO glass on the lower mold and then place the upper mold on the lower mold. At this time, multiple detection components will simultaneously contact the top of the ITO glass, so that each detection point of the ITO glass can be determined at the same time and quickly. There is no need to rearrange the detection points every time a new ITO glass is replaced, thereby quickly detecting the heating uniformity of the ITO glass and improving the detection speed and efficiency.

[0011] Furthermore, even if new ITO glass is replaced, each test piece is placed against the same position on the ITO glass, thus ensuring that the test point position of each ITO glass is consistent, avoiding inaccurate data due to human operation, and thus ensuring the accuracy of the test results.

[0012] Furthermore, the upper mold corresponding to the detection component has mounting holes, which are through holes;

[0013] The detection component includes a cylindrical probe connector. The upper part of the probe connector is fixed in the mounting hole in a one-to-one correspondence. When the lower mold and the upper mold are closed, the bottom of the probe connector abuts against the ITO glass. The inner cavity of the probe connector has a temperature measuring probe, which contacts the bottom end face of the inner cavity of the probe connector in a one-to-one correspondence.

[0014] The upper mold top corresponding to the mounting hole has a limiting component, and the limiting component has a through hole communicating with the corresponding mounting hole; the end of the temperature probe away from the probe connector is connected to a temperature measuring wire, and the outer periphery of the temperature measuring wire is covered with a fixing plug, the diameter of the fixing plug decreasing from top to bottom, the lower diameter of the fixing plug being smaller than the diameter of the through hole, and the upper diameter of the fixing plug being larger than the diameter of the through hole, and the fixing plugs are in a one-to-one correspondence with the through holes in an interference fit.

[0015] Through the above technical solution, by setting the fixing plug inside the limiting component, the upper part of the fixing plug is interference-fitted with the through hole, which can ensure the connection stability between the fixing plug and the limiting component, and avoid displacement, shaking or other displacement of the temperature probe during the glass detection process, thereby ensuring the stability of the temperature probe and improving the accuracy of the detection results.

[0016] Furthermore, the limiting member is integrally formed with the upper mold.

[0017] With the above technical solution, the limiting component and the upper mold are integrally formed, and there are no connection points or seams between the limiting component and the upper mold. This allows it to better withstand external pressure, impact and torque, thereby improving mechanical strength and stability.

[0018] Furthermore, the lower mold includes a rectangular lower support plate, each of the four corners of which has a first notch. A first limiting strip is provided on the lower support plate between adjacent first notches, and the four first limiting strips form the recess. A first notch is provided on a set of two parallel first limiting strips, one end of which extends into the lower support plate, and the other end of which passes through the corresponding first limiting strip and extends outward.

[0019] The upper mold includes a rectangular upper support plate with a second notch at each of the four corners. A second limiting strip is provided on the upper support plate between adjacent second notches. A second notch is provided on a set of two parallel second limiting strips. One end of the second notch extends into the upper support plate, and the other end of the second notch extends outward through the corresponding second limiting strip.

[0020] Through the above technical solution, the setting of the first notch and the first notch facilitates the routing of thermocouple wires for ITO glass, thereby facilitating the display of the actual working state of ITO glass and realizing the function of this device to test the uniformity of ITO glass.

[0021] By setting the second notch and the second notch, although the first notch and the first notch can complete the routing of the thermocouple wires of the ITO glass, if the corresponding second notch and the second notch are not set when the upper mold is installed, the connection between the ITO glass and the thermocouple wires will be blocked by the upper mold. The second notch and the second notch can facilitate the inspection of the connection between the ITO glass and the thermocouple wires, thereby ensuring the normal conduct of the test.

[0022] Furthermore, the detection components are provided in multiple sets, and each set of detection components is provided with multiple detection components. The multiple sets of detection components are arranged sequentially along the length direction of the upper support plate, and the multiple detection components of each set of detection components are arranged sequentially along the width direction of the upper support plate.

[0023] By using the above technical solution, and by setting up multiple groups, each group including multiple test pieces, comprehensive data on the heating uniformity of ITO glass can be collected, avoiding inaccurate test results due to insufficient local testing.

[0024] Furthermore, the upper support plate has a third notch that extends through the thickness direction of the upper support plate; the lower support plate has a fourth notch that extends through the thickness direction of the lower support plate.

[0025] By using the above technical solution, the weight of the upper mold and the lower mold can be reduced by setting the third and fourth notches, thereby reducing the difficulty of transporting the upper mold and the lower mold and improving the transport efficiency.

[0026] Furthermore, the bottom of the lower mold is provided with multiple bosses.

[0027] By using the above technical solution, the setting of the boss can leave a gap between the bottom of the lower mold and the ground or operating platform, which facilitates the handling of the lower mold and improves handling efficiency.

[0028] The above solution has the following advantages:

[0029] 1. By setting up multiple testing components, each time the heating uniformity is tested, simply place the ITO glass on the lower mold and then place the upper mold on the lower mold. At this time, multiple testing components will simultaneously contact the top of the ITO glass, so that each testing point of the ITO glass can be determined simultaneously and quickly. There is no need to rearrange the testing points every time a new ITO glass is replaced, thus quickly testing the heating uniformity of the ITO glass, thereby improving the testing speed and efficiency. In addition, even if a new ITO glass is replaced, each testing component is pressed against the same position on the ITO glass, thus ensuring that the test point position of each ITO glass is consistent, avoiding inaccurate data caused by human operation, and thus ensuring the accuracy of the test results.

[0030] 2. By setting the internal fixing plug of the limiting component, the upper part of the fixing plug is interference-fitted with the through hole, which can ensure the connection stability between the fixing plug and the limiting component, and avoid displacement, shaking or other displacement of the temperature probe during the glass detection process, thereby ensuring the stability of the temperature probe and improving the accuracy of the detection results.

[0031] 3. By integrating the limiting component with the upper mold, there are no connection points or seams between the limiting component and the upper mold, which can better withstand external pressure, impact and torque, thereby improving mechanical strength and stability.

[0032] 4. The first notch and the first notch facilitate the routing of the thermocouple wires for the ITO glass, thereby making it easier to demonstrate the actual working state of the ITO glass and enabling the device to test the uniformity of the ITO glass. Although the first notch and the first notch can complete the routing of the thermocouple wires for the ITO glass, if the corresponding second notch and the second notch are not provided when the upper mold is installed, the connection between the ITO glass and the thermocouple wires will be blocked by the upper mold. The second notch and the second notch facilitate the inspection of the connection between the ITO glass and the thermocouple wires, thereby ensuring the normal conduct of the test.

[0033] 5. By setting the third and fourth notches, the weight of the upper and lower molds can be reduced respectively, thereby reducing the difficulty of transporting the upper and lower molds and improving the transport efficiency.

[0034] 6. By setting up multiple groups, each group including multiple test pieces, comprehensive data on the heating uniformity of ITO glass can be collected, avoiding inaccurate test results due to insufficient local testing.

[0035] 7. By setting the boss, a gap can be left between the bottom of the lower mold and the ground or operating platform, which facilitates the handling of the lower mold and improves handling efficiency. Attached Figure Description

[0045] 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.

[0046] In a specific embodiment, such as Figure 1-7 As shown, a standard test fixture for detecting the heating uniformity of ITO glass includes a lower mold 2 and an upper mold 1. The lower mold 2 has a recess for fixing the ITO glass 15, and the upper mold 1 has multiple test pieces with gaps between adjacent test pieces. When the lower mold 2 and the upper mold 1 are closed, all test pieces are in contact with the ITO glass 15.

[0047] Each time the heating uniformity is tested, simply place the ITO glass 15 on the lower mold 2, and then place the upper mold 1 on the lower mold 2. At this time, multiple test pieces will simultaneously contact the top of the ITO glass 15, so that each test point of the ITO glass 15 can be determined simultaneously and quickly. There is no need to rearrange the test points every time a new ITO glass 15 is replaced, thus quickly testing the heating uniformity of the ITO glass 15, thereby improving the testing speed and efficiency. Even if a new ITO glass 15 is replaced, each test piece is pressed against the same position on the ITO glass 15, thus ensuring that the test point position of each ITO glass 15 is consistent, avoiding inaccurate data caused by human operation, and thus ensuring the accuracy of the test results.

When the lower mold 2 and the upper mold 1 are closed, the bottom of the probe connector 5 abuts against the ITO glass. The inner cavity of the probe connector 5 has a temperature measuring probe 3, which is in contact with the bottom end face of the inner cavity of the probe connector 5 in a one-to-one correspondence.

The diameter of the fixing plug 9 decreases from top to bottom. The lower diameter of the fixing plug 9 is smaller than the diameter of the through hole 8, and the upper diameter of the fixing plug 9 is larger than the diameter of the through hole 8. The fixing plug 9 is in a one-to-one correspondence with the through hole 8 and has an interference fit; after the upper part of the fixing plug 9 is interference-fitted with the through hole 8, it can ensure the connection stability between the fixing plug 9 and the limiting part 7, avoid the temperature probe 3 from shifting or shaking during the glass detection process, and thus ensure the stability of the temperature probe 3, thereby improving the accuracy of the detection results.

[0050] The limiting component 7 is integrally formed with the upper mold 1. After the limiting component 7 and the upper mold 1 are integrally formed, there are no connection points or seams between the limiting component 7 and the upper mold 1, which can better withstand external pressure, impact and torque, thereby improving mechanical strength and stability.

[0051] The lower mold 2 includes a rectangular lower support plate 201, with first notches 17 at each of its four corners.

A first notch 10 is provided between a set of two parallel first limiting strips 102, with one end of the first notch 10 extending into the lower support plate 201 and the other end passing through the corresponding first limiting strip 102 and protruding outwards. The upper mold 1 includes a rectangular upper support plate 101, with second notches 18 at each of its four corners. A first limiting strip 102 is provided between adjacent second notches 18 on the upper support plate 201. There is a second limiting strip 202; a set of two parallel second limiting strips 202 have a second notch 11, one end of the second notch 11 extends to the upper support plate 101, and the other end of the second notch 11 passes through the corresponding second limiting strip 202 and extends outward; in this specific embodiment, the distance between the second limiting strips 202 on both sides of the upper support plate 101 in the length direction is equal to the length of the lower support plate 201; along the width direction of the upper mold 1, the distance between the second limiting strips 202 on both sides of the lower support plate 201 in the width direction is equal to the width of the lower support plate 201; the upper mold 1 is covered and fastened on the lower mold 2; the first notch 10 and the first notch 17 facilitate the routing of thermocouple wires for ITO glass, thereby facilitating the display of the actual working state of ITO glass, thus realizing the function of this device to test the uniformity of ITO glass;

[0052] Although the first notch 10 and the first notch 17 can complete the routing of the thermocouple wires of the ITO glass, if the second notch 11 and the second notch 18 are not set accordingly when the upper mold 1 is installed, the connection between the ITO glass and the thermocouple wires will be blocked by the upper mold 1. The second notch 11 and the second notch 18 can facilitate the inspection of the connection between the ITO glass and the thermocouple wires, thereby ensuring the normal conduct of the test.

In this specific embodiment, the fourth notch 13 is a strip-shaped notch. The third notch 12 and the fourth notch 13 can reduce the weight of the upper mold 1 and the lower mold 2 respectively, thereby reducing the difficulty of transporting the upper mold 1 and the lower mold 2 and improving the transport efficiency.

[0054] The testing components are arranged in multiple groups, with each group containing multiple testing components. These groups are arranged sequentially along the length of the upper support plate 101, and the multiple testing components in each group are arranged sequentially along the width of the upper support plate 101. By setting up multiple groups, each containing multiple testing components, comprehensive data on the heating uniformity of the ITO glass can be collected, avoiding inaccurate test results due to insufficient local testing. The number of groups and the quantity in each group can be designed according to the testing requirements. In this specific embodiment, three groups are provided, with each group containing three components.

[0055] The bottom of the lower mold 2 is provided with multiple bosses 14; the bosses 14 can leave a gap between the bottom of the lower mold 2 and the ground or operating platform, which facilitates the handling of the lower mold 2 and improves handling efficiency.

[0056] During assembly, place the lower mold 2 on a flat, clean work surface and ensure that the temperature and humidity of the test environment are constant. The room temperature is 22-23℃ and the humidity is 50-60%. Place the ITO glass 15 inside the top of the lower mold 2 and lead out the multiple thermocouple wires 16 of the ITO glass 15 from the first notch 10 or the first notch 17 respectively. Place the upper mold 1 above the heated glass and visually ensure that the bottom of the probe connector 5 is in contact with the top surface of the ITO glass 15.

[0057] Insert the temperature probe 3 into and pass through the corresponding through hole 8 and mounting hole 4 in sequence.
