Abstract
Description
Technical Field
[0001] The utility model relates to the field of manufacturing liquid crystal glass substrates, and specifically relates to a positioning device for processing and forming liquid crystal glass substrates. Background Technique
[0002] Liquid crystal glass substrates are an important part of liquid crystal flat panel displays and are also one of the irreplaceable raw materials in the production process of liquid crystal panels. They mainly play a role in fixing liquid crystal molecules, and the touch functions of some displays are also realized based on glass substrates.
[0003] There are mainly three production processes for liquid crystal glass substrates: the floating method, the downward drawing method through a flow hole, and the overflow method. Among them, the overflow method has the advantages of better controllability of surface characteristics, no need for grinding, and simpler processes, and is particularly suitable for producing ultra-thin flat glass with a thickness less than 2 mm.
[0004] During the process of forming liquid crystal glass substrates using the overflow method, a core clamping and traction roller needs to be used. The clamping force state of the core clamping and traction roller is currently in an uncontrolled state, and it is impossible to keep its clamping force in a constant and stable state, thus having a greater impact on the forming process of liquid crystal glass substrates. Content of the Utility Model
[0005] The purpose of the utility model is to provide a positioning device for processing and forming liquid crystal glass substrates, which effectively solves the problem that during the production process of liquid crystal glass substrates, the core clamping and traction roller cannot be precisely controlled, affecting the forming process of liquid crystal glass substrates.
[0006] The technical solution of the utility model is as follows:
[0007] A positioning device for processing and forming liquid crystal glass substrates includes a mounting panel. Above the mounting panel, two mutually parallel positioning rods are symmetrically arranged. On each positioning rod, sliding rings are symmetrically arranged. On two sliding rings on adjacent positioning rods, bearing seats are symmetrically arranged and are perpendicularly distributed to the positioning rods. Inside the two bearing seats, a clamping and traction roller one and a clamping and traction roller two are movably connected. At the ends of the clamping and traction roller one and the clamping and traction roller, traction roller wheels are provided.
[0008] A fixed limiting component is arranged between the clamping and traction roller one and the positioning rod. The fixed limiting component is used to fix the clamping and traction roller one on the positioning rod. On the side of the clamping and traction roller two away from the clamping and traction roller one, a pressure sensor is provided. On one side of the pressure sensor, a cylinder is provided.
[0009] Furthermore, the cross-section of the positioning rod is circular. On the outer wall of the positioning rod, limiting grooves are arranged in a circumferential arrangement. Inside the inner wall of the sliding ring, balls are movably embedded, and the balls are slidably matched in the limiting grooves.
[0010] Further, a bearing is fixedly installed inside the bearing seat. The first clamping and traction roller and the second clamping and traction roller are rotatably connected inside the bearing, and the two extend out of the bearing seat and are parallel to each other.
[0011] Further, the fixing and limiting assembly includes a retaining plate, a groove, a jack, and a limiting insert. The retaining plate is fixedly connected to the positioning rod. The groove is provided on the sliding ring of the first clamping and traction roller, and the groove is provided on the side of the sliding ring away from the retaining plate.
[0012] Further, the jack penetrates through the positioning rod. When the first clamping and traction roller contacts the retaining plate, the limiting insert is simultaneously inserted into the groove and the jack to fix the first clamping and traction roller.
[0013] Further, mating grooves are symmetrically provided on the bearing seat. A locking insertion plate is fixedly connected to the top of the sliding ring. The locking insertion plate is inserted into the mating groove, and the locking insertion plate and the bearing seat are fixedly connected by threads.
[0014] Further, an electrically connected electric air valve is provided on the air cylinder. The electric air valve is electrically connected to a DCS system device, and the DCS system device is electrically connected to the pressure sensor.
[0015] The advantages of the present utility model are as follows:
[0016] 1. By arranging parallel positioning rods, the two bearing seats can slide on the positioning rods through the sliding rings. When one sliding ring is fixed, the bearing seat will be fixed. Under the action of the air cylinder, the other bearing seat is pushed to move, thereby adjusting the distance between the two traction roller wheels. After adjustment, the clamping force when the glass clamping plate passes through the gap is kept constant, so that a constant clamping force is applied to the glass substrate, ensuring a consistent thickness when the glass substrate passes through the gap, and optimizing the processing technology for the forming of the liquid crystal glass substrate.
[0017] 2. By arranging the fixing and limiting assembly, when the sliding ring at the bottom of the first clamping and traction roller contacts the retaining plate, it is blocked. At this time, the groove and the jack coincide exactly. The limiting insert is inserted into the two to fix the sliding ring, thereby keeping the first clamping and traction roller and the bearing seat fixed. The distance is controlled by adjusting the position of the bearing seat on the other side, which is convenient, simple and flexible.
[0018] 3. In the present utility model, a pressure sensor is connected to the air cylinder. When the liquid crystal glass substrate is being formed, the pressure on the bearing seat of the second clamping and traction roller will be transmitted to the pressure sensor, and the pressure is then transmitted to the DCS system device. There is a rated pressure value in the DCS system device. By comparing with the rated pressure value, the electric air valve is controlled to move the telescopic rod of the air cylinder, thereby realizing the automatic movement of the bearing seat of the second traction roller, automatically adjusting the pressure magnitude, and making the device more intelligent.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0026] As Figures 1 to 5 shown, the present utility model provides a positioning device for processing the formation of liquid crystal glass substrates, which includes a mounting panel 1. Above the mounting panel 1, two parallel positioning rods 2 are symmetrically arranged. One end of the positioning rod 2 is fixed on the mounting panel 1. By arranging them in parallel, the bearing seats 4 can slide parallel to each other, thereby ensuring that during the process of processing liquid crystal glass substrates, the gaps are consistent.
[0027] A sliding ring 3 is symmetrically arranged on each positioning rod 2. Through the sliding ring 3, movement in the positioning can be achieved. On the two sliding rings 3 on adjacent positioning rods 2, bearing seats 4 perpendicular to the positioning rod 2 are symmetrically arranged. Inside the two bearing seats 4, a clamping and traction roller I 5 and a clamping and traction roller II 6 are movably connected. Traction roller wheels 7 are arranged at the ends of the clamping and traction roller I 5 and the clamping and traction roller. Through the arranged traction roller wheels 7, during the processing of the glass substrate, it flows down through the gap between the two traction roller wheels 7;
[0028] A fixed limiting component is arranged between the clamping and traction roller I 5 and the positioning rod 2. The fixed limiting component is used to fix the clamping and traction roller I 5 on the positioning rod 2. On the side of the clamping and traction roller II 6 away from the clamping and traction roller I 5, a pressure sensor 8 is arranged. On one side of the pressure sensor 8, a cylinder 9 is arranged. The telescopic rod of the cylinder 9 is connected to the bearing seat 4, so that the bearing seat 4 can be pushed to move, and the distance between the two bearing seats 4 can also be kept fixed.
[0029] The vertical cross-section of the positioning rod 2 is circular. On the outer wall of the positioning rod 2, limiting grooves 10 are arranged in a circumferential arrangement. On the inner wall of the sliding ring 3, balls 11 are movably embedded. The balls 11 are slidably matched in the limiting grooves 10, so that the sliding ring 3 can slide on the positioning rod 2 better.
[0030] A bearing 12 is fixedly installed inside the bearing seat 4. The clamping and traction roller I 5 and the clamping and traction roller II 6 are rotatably connected inside the bearing 12, and the two pass through the bearing seat 4 and are parallel to each other. Through the arranged bearing 12, the clamping and traction roller I 5 and the clamping and traction roller II 6 can rotate inside the bearing 12, so that when the traction roller wheels 7 form the liquid crystal glass substrate, they rotate.
[0031] The fixed limiting component includes a retaining piece 13, a groove 14, a jack 15, and a limiting insert 16. The retaining piece 13 is fixedly connected to the positioning rod 2. The groove 14 is arranged on the sliding ring 3 on the clamping and traction roller I 5, and the groove 14 is arranged on the side of the sliding ring 3 away from the retaining piece 13.
[0032] The jack 15 penetrates through the positioning rod 2. When the clamping and traction roller I 5 contacts the retaining piece 13, the limiting insert 16 is simultaneously inserted into the groove 14 and the jack 15 to fix the clamping and traction roller I 5. With the arranged fixed limiting component, the position of the clamping and traction roller I 5 is fixed, the position of the clamping and traction roller II 6 can be flexibly adjusted, the adjustment of the gap is realized, and it can be flexibly adjusted according to the production of liquid crystal glass substrates with different thicknesses.
[0033] The bearing housing 4 is symmetrically provided with mating grooves 17. The top of the sliding ring 3 is provided with a locking plug 18 fixedly connected thereto. The locking plug 18 is inserted into the mating groove 17, and the locking plug 18 and the bearing housing 4 are fixedly connected by threads, realizing the connection between the bearing housing 4 and the sliding ring 3. Moreover, the fixation is achieved by screws, which also facilitates the disassembly of the two and is conducive to maintenance.
[0034] An electrically connected electric air valve 19 is provided on the air cylinder 9. The electric air valve 19 is electrically connected to a DCS system device 20. The DCS system device 20 is electrically connected to the pressure sensor 8. There is a rated pressure value in the DCS system device 20. By comparing with the rated pressure value, the electric air valve 19 is controlled to move the telescopic rod of the air cylinder 9, thereby realizing the automatic movement of the bearing housing 4 on the second traction roller and automatically adjusting the pressure magnitude, making the device more intelligent.
[0035] The detailed usage method and functions of the above embodiments:
[0036] When it is necessary to manufacture a liquid crystal glass substrate, first insert the bearing housing 4 into the locking plug 18 on the sliding ring 3. After aligning the mating groove 17 with the locking plug 18 and inserting it to the bottom, use screws to fix the bearing housing 4 and the locking plug 18. The locking plug 18 and the sliding ring 3 are fixedly connected. Move the bearing housing 4 on the first clamping traction roller 5 so that the sliding ring 3 fits on the baffle 13. When it fits on the baffle 13, insert the limit insert 16 into the groove 14 on the sliding ring 3 and the jack 15 on the positioning rod 2, realizing the fixation of the position of the first clamping traction roller 5.
[0037] The air cylinder 9 is fixedly connected to the mounting panel 1. Start the air cylinder 9 to drive the connected bearing housing 4 to move and drive the second clamping traction roller 6 to change its position. After adjusting the position, keep the air cylinder 9 stationary, realizing the fixation of the position of the traction roller wheels 7 at the ends of the first clamping traction roller 5 and the second clamping traction roller 6. The liquid crystal glass substrate will flow down from the gap between the two, and the traction roller wheels 7 will roll and clamp the liquid crystal glass substrate during the forming process. The clamping force will act on the pressure sensor 8 through the second clamping traction roller 6, and thus the vertical pressure will be transmitted to the DCS system device 20. The pressure sensor 8 and the electric air valve 19 are respectively connected to the signal input end and the output end of the DCS system device 20.
[0038] Set a constant pressure value X through the DCS system device 20. If the pressure sensor 8 measures that the current pressure is less than X, a signal is given to the electric air valve 19 to increase the pressure of the air cylinder 9, so that the second clamping traction roller 6 is extruded towards the first clamping traction roller 5.
[0039] When the pressure sensor 8 measures that the current pressure is equal to X, a signal is given to the electric air valve 19 to keep the pressure of the air cylinder 9 and make the second clamping traction roller 6 stable.
[0040] When the pressure sensor 8 detects that the current pressure is greater than X, a signal is given to the electric air valve 19 to reduce the pressure of the cylinder 9, so that the pressure value of the clamping and traction roller II 6 on the clamping and traction roller I 5 is reduced.
[0041] Through timely detection, the pressure value during the processing of the liquid crystal glass can be kept constant, thereby improving the processing and forming effect of the liquid crystal glass substrate.
[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
