Description

Technical Field

[0001] This invention relates to the field of TFT glass manufacturing technology, specifically to a clamping device, a pushing system, and a method for producing electrode bricks in TFT substrate glass production. Background Technology

[0002] In the field of substrate glass manufacturing, TFT-LCD liquid crystal glass furnaces are currently the most widely used technology for melting glass. By utilizing the good electrical conductivity of glass in a high-temperature molten state, electrodes are inserted into the glass melt. Due to the Joule effect, the electrical energy inside the glass melt is converted into heat energy, thereby achieving the melting of glass.

[0003] In the production of TFT-LCD liquid crystal glass substrates, the stability of the temperature and flow fields of the molten glass within the furnace is a decisive factor in product quality. Since the furnace used in substrate glass production is an electric flux furnace, melting is achieved by generating heat through the resistive conductivity of the molten glass itself. The internal temperature of the molten glass is high, and convection is strong. During use, the electrodes are gradually and slowly eroded by the impact of convection and temperature. Therefore, to ensure the long-term stability of the temperature and flow fields within the furnace and the effective heating of the electrodes, the electrodes need to be periodically advanced. The verticality and horizontality of the electrodes are closely related to the distribution of electric field lines in the molten glass within the furnace. Therefore, the electrodes need to maintain uniform verticality and horizontality over a long period. The currently used structure is a screw-type propulsion system, including eight screw propulsion rods and a bottom lifting device, which can effectively maintain the lateral horizontality of the electrodes. However, this structure can only effectively prevent the electrodes from tilting backward; it cannot prevent the electrodes from tilting forward. Because the electric field lines at the bottom of the electrodes are dense, forward tilting of the electrodes will lead to accelerated erosion of the bottom support bricks. Uneven lateral electric field lines within the molten glass will alter convection and temperature, thus causing fluctuations in the equipment itself and the quality of the process. Summary of the Invention

[0004] To address the problems in existing technologies, such as electrode tilting leading to increased erosion of the bottom pad brick, uneven electric field lines in the molten glass altering convection and temperature, and affecting equipment lifespan and process quality, this invention provides an electrode brick pressing device, a pushing system, and a method for TFT substrate glass production.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A clamping device for electrode bricks in TFT substrate glass production includes an insulating ball box containing a plurality of insulating balls. The insulating balls abut against the top of the electrode brick to be pushed, thereby limiting the top of the electrode brick. A clamping mechanism is provided on the insulating ball box for limiting the insulating ball box and the electrode pushing frame.

[0006] Preferably, the fastening mechanism includes suspensions respectively disposed at both ends of the insulating ball box, and the suspensions are provided with fixing bolts.

[0007] Preferably, the fixing bolt is threadedly connected to the suspension, and the fixing bolt passes through the top of the suspension and abuts against the electrode pusher.

[0008] Preferably, the suspension is made of stainless steel.

[0009] Preferably, the suspension is perpendicular to the insulating ball bearing box.

[0010] Preferably, the insulating ball is made of aluminum oxide.

[0011] Preferably, the insulating balls are provided in a set of four and are evenly distributed inside the insulating ball box.

[0012] A TFT substrate glass production electrode brick pushing system includes the aforementioned TFT substrate glass production electrode brick pressing device.

[0013] The TFT substrate glass production electrode brick propulsion system further includes a lifting mechanism and an electrode propulsion mechanism. The electrode propulsion mechanism is arranged along the electrode brick propulsion direction to propel the electrode brick. The lifting mechanism is located at the lower end of the electrode propulsion frame, and the top end of the lifting mechanism abuts against the bottom end of the electrode brick to limit the bottom end of the electrode brick.

[0014] A method for advancing electrode bricks in TFT substrate glass using the above-mentioned propulsion system includes the following steps: Adjust the electrode brick to a horizontal position; Fix the electrode brick clamping device to the electrode pusher frame, and adjust the electrode brick clamping device so that the insulating ball is in close contact with the top surface of the electrode brick after it has been adjusted to a horizontal state; After the insulating ball bearings are tightly attached to the top surface of the electrode brick, the electrode brick is pushed forward. When the top of the electrode brick is close to disengaging from the electrode brick clamping device, the relative position of the electrode brick clamping device and the electrode pushing frame is adjusted and fixed. The electrode brick is then pushed forward until it reaches the target position, thus completing the pushing of the electrode brick.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides an electrode brick clamping device for TFT substrate glass production. The device uses an insulating ball bearing box fixed to the top of the electrode brick via an electrode pushing frame. The insulating ball bearing box contains several insulating balls. By abutting the top of the electrode brick to be pushed, the top of the electrode brick is limited, effectively preventing the electrode brick from tipping forward during the pushing process. This avoids the problems caused by the electrode tipping forward, such as increased erosion of the bottom pad brick, uneven electric field lines in the molten glass altering convection and temperature, etc., thus ensuring that the equipment itself and process quality are not affected. The device is simple, safe and controllable in use, easy to install, and can be upgraded on existing production lines without shutdown, resulting in low modification costs. It effectively solves a series of equipment damage and process quality fluctuation problems caused by changes in verticality during electrode pushing.

[0016] The clamping mechanism includes suspensions respectively located at both ends of the insulated ball bearing box, with fixing bolts on the suspensions. The fixing bolts are threadedly connected to the suspensions and pass through the top of the suspensions to abut against the electrode propulsion frame. This provides support for the entire clamping device while allowing for the fixing and disassembly of the clamping device and the electrode propulsion frame, as well as horizontal position adjustment and limitation at any time. This increases the flexibility of the clamping device and allows it to operate throughout the entire electrode propulsion process.

[0017] The suspension is made of stainless steel, which is beneficial for the effective support of the clamping device.

[0018] The insulating balls are made of aluminum oxide and serve to provide insulation, heat resistance, and support.

[0019] The present invention also provides a TFT substrate glass production electrode brick pushing system, including the above-mentioned TFT substrate glass production electrode brick pressing device. The pushing system can simultaneously position the electrode brick at the top, bottom and side during the pushing process, ensuring that the electrode brick maintains a long-term uniform verticality and horizontality during the pushing process, so as to avoid the electrode brick from tilting forward or backward, and avoid the aggravation of local corrosion of the electrode brick, which affects the stability of the equipment and the stability of production quality.

[0020] The present invention also provides a method for advancing electrode bricks in TFT substrate glass production using the above-mentioned advancing system. This method uses an electrode brick clamping device to limit the top of the electrode brick during the advancing process, preventing the electrode brick from falling forward, and ensuring that the electrode brick maintains uniform verticality and horizontality throughout the advancing process. This avoids the impact of severe local corrosion of the electrode brick on the production life of the equipment and the quality of the produced products. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0031] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0032] See Figure 1 The present invention discloses an electrode brick pressing device for TFT substrate glass production, including an insulating ball box 1, wherein a plurality of insulating balls 3 are disposed in the insulating ball box 1, the insulating balls 3 abut against the top of the electrode brick 9 to be pushed, thereby limiting the top of the electrode brick 9; the insulating ball box 1 is provided with a fastening mechanism for fixing the insulating ball box 1 to the electrode pusher 6.

[0033] The fastening mechanism includes suspensions 2 respectively located at both ends of the insulating ball box 1. The suspensions 2 are provided with fixing bolts 4, which are threadedly connected to the suspensions 2 and pass through the top of the suspensions 2 to abut against the electrode pusher 6.

[0034] Preferably, to ensure the supporting function of the suspension 2, the suspension 2 is made of stainless steel and is perpendicular to the insulating ball box 1; in addition to limiting the insulating balls 3, the insulating ball box 1 can also effectively prevent the risk of grounding short circuit breakdown caused by contact between the electrode brick 9 and the electrode pusher frame 6.

[0035] To ensure the insulating, heat-resistant, and supportive functions of the insulating balls 3, it is preferable that the insulating balls 3 are made of aluminum oxide, and that there are four insulating balls 3 arranged evenly inside the insulating ball box 1.

[0036] See Figure 2 This invention discloses an electrode brick pushing system for TFT substrate glass production, including the aforementioned electrode brick pressing device 5, lifting mechanism 8, and electrode pushing mechanism 7. The electrode pushing mechanism 7 is arranged along the pushing direction of the electrode brick 9 to push the electrode brick 9. The lifting mechanism 8 is arranged at the lower end of the electrode pushing frame 6, and the top end of the lifting mechanism 8 abuts against the bottom end of the electrode brick 9 to limit the bottom end of the electrode brick 9.

[0037] This propulsion system enables the electrode brick to be positioned simultaneously from the top, bottom, and sides during the propulsion process, ensuring that the electrode brick maintains a consistent verticality and horizontality over a long period of time. It prevents the electrode brick from tilting forward or backward, thus avoiding the aggravation of local corrosion of the electrode brick, which would affect the stability of the equipment and the stability of production quality.

[0038] See Figure 3 The present invention also provides a method for producing electrode bricks using the above-mentioned propulsion system on TFT substrate glass, comprising the following steps: S1: Adjust electrode brick 9 to a horizontal position; S2: Fix the electrode brick clamping device 5 to the electrode pusher frame 6, and adjust the electrode brick clamping device 5 so that the insulating ball 3 is in close contact with the top surface of the electrode brick 9 after it has been adjusted to a horizontal state. S3: After the insulating ball 3 is tightly attached to the top surface of the electrode brick 9, the electrode brick 9 is pushed forward. When the top of the electrode brick 9 is close to disengaging from the electrode brick pressing device 5, the relative position of the electrode brick pressing device 5 and the electrode pushing frame 6 is adjusted and fixed. The electrode brick 9 is then pushed forward until it reaches the target position, thus completing the pushing of the electrode brick 9.

[0039] During the long-term operation of the kiln, when advancing the electrodes, repeating the above operation can ensure that the electrode bricks are advanced with uniform verticality and horizontality, thus preventing the electrode bricks from tipping forward.

[0040] In summary, this invention provides an electrode brick clamping device, a pushing system, and a method for TFT substrate glass production.

It can be upgraded on existing production lines without shutting down the line. It effectively solves the problems of equipment damage and process quality fluctuations caused by changes in verticality during electrode pushing.
