Description

Technical Field

[0001] The invention relates to the technical field of substrate glass manufacturing, and in particular to a substrate glass liquid level probe mounting fixture and a use method thereof. Background Art

[0002] In the production process of liquid crystal glass substrates, the control of the glass liquid level in the kiln is one of the three elements of kiln stability. The stability of the liquid level is not only related to the balance of the temperature and flow field of the glass liquid inside the kiln, but also a key factor in reducing platinum defects and bubble defects. Given that the surface of the substrate glass production kiln is often covered with a floating sand layer, in order to obtain more accurate data on the kiln liquid level, the industry generally chooses to install a liquid level detection device in a specific channel.

[0003] At present, most manufacturers in the TFT substrate glass industry use a mobile probe measurement method. The fatal flaw of this technology is that the probe is easy to stick to the material during the measurement process, causing the automatic control system of the feeder to be unreliable and the failure rate is high. Therefore, the patent document "CN221404418U" provides a TFT substrate glass large lead-out channel liquid level measurement device that prevents the probe from sticking to the material, including a mobile probe, a liquid level lead-out tube and a probe rod; the liquid level lead-out tube has glass liquid; the mobile probe extends into the liquid level lead-out tube; one end of the mobile probe is connected to the probe rod, and the contact surface of the other end of the mobile probe with the glass liquid is an arc shape; the measuring device uses the arc design of the end of the mobile probe to make the probe contact with the liquid surface reliably, and the measurement voltage can be quickly detected, thereby shortening the contact time between the probe and the liquid surface, reducing the risk of sticking to the material, and successfully solving the technical problem of probe sticking to the material in the measurement of the glass liquid level height.

[0004] However, although the device solves the technical problem of the probe easily sticking to the material when measuring the glass liquid level, it also brings about new challenges. The liquid level lead-out pipe is built into the insulation brick, and the temperature of the glass liquid near the liquid level lead-out pipe is greater than 1500℃. During the installation of the probe, due to the long length of the probe and the high temperature and humidity of the on-site environment, it is difficult to maintain stability for a long time by manual hand-held installation, and it is easy for the probe to touch the wall of the liquid level detection tube and the probe installation to be eccentric. Once the probe touches the tube wall, it may not only cause deformation of the probe end, but also cause distortion of the liquid level detection due to scratches, and even produce platinum-rhodium defects. When the probe is installed eccentrically, due to the presence of bubbles on the outer high edge of the glass liquid at the liquid level detection port, it is easy to cause glass hanging on the end of the probe, which in turn causes glass or bubble defects.

[0005] Therefore, how to ensure the stability of probe installation has become a key technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0006] The object of the present invention is to provide a substrate glass liquid level probe installation fixture and a use method to overcome the problem of insufficient stability of manually holding the installation probe in the prior art.

[0007] The present invention solves the above technical problems through the following technical solutions: A mounting fixture for a substrate glass liquid level measuring device comprises a probe rod clamping portion and a retractable support portion, wherein the probe rod clamping portion is connected to the support portion; during installation, the probe rod of the substrate glass liquid level measuring device is placed on the probe rod clamping portion.

[0008] A further improvement of the present invention is that the telescopic support portion comprises a telescopic rod and a fixed base which are sequentially connected from top to bottom.

[0009] A further improvement of the present invention is that the fixed base is in an I-shape.

[0010] A further improvement of the present invention is that the probe rod clamping portion is a V-shaped structure.

[0012] A further improvement of the present invention is that the probe rod clamping portion is made of platinum material.

[0013] A further improvement of the present invention is that the support portion is made of platinum material.

[0014] A further improvement of the present invention is that the connection between the probe rod clamping portion and the support portion is welding.

[0015] The present invention also provides a method for using a mounting fixture for a substrate glass liquid level measuring device, using the mounting fixture as described above, comprising the following steps: Place the support part on the insulation brick below the probe rod, and adjust the position of the support part so that the support part and the liquid level outlet pipe of the substrate glass liquid level measuring device are in a vertical alignment state; Place the probe rod on the probe rod clamping part and adjust the height of the support part to make the probe rod horizontal; Use the substrate glass liquid level measuring device to lock the probe rod, remove the installation fixture, and complete the installation.

[0016] A further improvement of the present invention is that the working environment temperature of the installation fixture is 70-80 degrees Celsius.

[0017] Compared with the prior art, the positive and progressive effects of the present invention are: The installation fixture for the substrate glass liquid level measuring device provided by the present invention includes a probe rod clamping portion and a retractable support portion, wherein the probe rod clamping portion is connected to the support portion; during installation, the probe rod of the substrate glass liquid level measuring device is placed on the probe rod clamping portion, and the use of this device can improve the stability of the probe installation and reduce the occurrence of platinum-rhodium defects, glassy or bubble defects and other problems during substrate glass liquid level measurement. On the one hand, the installer can quickly and accurately install the probe in place, effectively preventing the problem of deformation of the probe end due to touch during the installation process; on the other hand, through the use of this installation fixture, the probe can be more easily centered during installation, so that the axis of the probe is consistent with the axis of the liquid level lead-out tube. This centering effect not only avoids the measurement error caused by the centering deviation, but also can further avoid the phenomenon of the probe end and the liquid level lead-out tube wall being scratched, effectively preventing the touch damage during the probe measurement process.

[0018] Furthermore, the retractable support part includes a telescopic rod and a fixed base connected in sequence from top to bottom. The design of the telescopic rod allows the height of the support part to be adjusted according to actual needs, ensuring that the probe can be accurately placed at the required position, thereby improving the accuracy and reliability of the measurement; the fixed base serves as the lower end of the support part, providing a stable supporting foundation, ensuring the stability of the entire fixture during the installation process, and preventing measurement errors or probe damage caused by shaking or tilting.

[0019] Furthermore, the fixed base is I-shaped, and its cross-sectional shape can effectively disperse the pressure it bears, making the force distribution more even, and can withstand greater vertical pressure without easily deforming, thereby enhancing the stability of the base and ensuring that the clamp is not prone to shaking or tilting during installation and use.

[0020] Furthermore, the probe rod clamping portion is designed as a V-shaped structure, which facilitates the placement of the horizontal portion of the probe and the removal of the installation fixture, improves the convenience of the installation fixture, and not only simplifies the installation process but also improves work efficiency.

[0021] Furthermore, the probe rod clamping portion is a detachable annular structure, so that the probe rod clamping portion can be easily assembled and disassembled as needed; the probe rod clamping portion with an annular structure can distribute the clamping force more evenly, thereby enhancing the clamping stability.

[0024] Furthermore, the probe rod clamping portion and the support portion are connected by welding, which can ensure the structural stability between the two and prevent them from loosening or falling off due to external forces, thereby helping to improve the working reliability of the entire installation fixture.
