Description

Technical Field

[0001] This utility model belongs to the field of glass inkjet printing technology, and in particular relates to a novel inkjet printing device for glass substrates. Background Technology

[0002] Glass substrate inkjet printing equipment is a highly precise non-contact digital manufacturing equipment. It uses inkjet printing technology to deposit functional inks (such as metal nanoparticle inks, insulating materials, organic light-emitting materials, photoresists, quantum dot inks, etc.) directly onto designated locations on glass substrates in precisely controlled droplet form to form the required patterns or functional layers. Its core function is to achieve micron or even submicron level patterned deposition on glass substrates, replacing or supplementing traditional processes such as photolithography, etching, vapor deposition, and screen printing.

[0003] Therefore, currently, ordinary glass is first cut, then screen-printed with patterns, and then tempered. The tempering process solidifies the patterns and prevents them from fading. However, this method prevents the glass from being cut again, otherwise it will shatter. To address this problem, we provide a novel inkjet printing device for glass substrates. Utility Model Content

[0004] The purpose of this invention is to provide a novel inkjet printing device for glass substrates. By first screen printing patterns onto the glass substrates and then curing them in a sintering box, the glass substrates can be guaranteed not to crack after cutting.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model provides a glass substrate inkjet printing device, including a loading machine, a directional conveyor frame, and storage racks located on both sides of the directional conveyor frame. A four-sided grinder is located at the right end of the directional conveyor frame, and an intelligent cleaning machine is located at the right end of the four-sided grinder. A three-way conveyor is located to the right of the intelligent cleaning machine. The three-way conveyor includes two sets of bidirectional conveying components arranged symmetrically and a linkage conveyor frame located between the two sets of bidirectional conveying components. One set of bidirectional conveying components is aligned with the intelligent cleaning machine in the left-right direction. A sintering box is located at the left end of the other set of bidirectional conveying components, and a unloading machine is located at the left end of the sintering box. A digital inkjet printer is located at the right end of both sets of three-way conveyors.

[0007] The present invention is further configured such that the bidirectional conveying assembly includes a roller conveyor frame and a belt conveyor frame, the roller conveyor frame and the belt conveyor frame are arranged alternately from left to right, and the conveying directions of the roller conveyor frame and the belt conveyor frame are perpendicular to each other.

[0008] The present invention is further configured such that the conveying direction of one set of roller conveyor frames is consistent with the conveying direction of the intelligent cleaning machine and the digital inkjet printer, and the conveying direction of the other set of roller conveyor frames is consistent with the conveying direction of the sintering box and the other set of digital inkjet printers.

[0009] The present invention is further configured such that the conveying direction of the belt conveyor is consistent with the conveying direction of the linkage conveyor.

[0010] The present invention is further configured such that a compressor and a gas storage tank are provided on the outside of the sintering box at the positions of the preheating sintering zone, the high-temperature sintering zone and the annealing zone, and each group of adjacent compressors and gas storage tanks are respectively connected to the interior of the corresponding preheating sintering zone, the high-temperature sintering zone and the annealing zone.

[0011] The present invention is further configured such that an intelligent robotic arm is fixed above each set of storage racks.

[0012] The present invention is further configured such that the internal space of the sintering box is arranged from right to left as follows: a preheating sintering zone, a high-temperature sintering zone, an annealing zone one, an annealing zone two, an annealing zone three, an annealing zone four, an annealing zone five, and a cooling zone.

[0013] This invention has the following advantages: First, the glass substrate is transferred to the interior of the corresponding digital inkjet printer for inkjet printing, and then transferred to the corresponding sintering box via a three-way conveyor. The preheating sintering zone and high-temperature sintering zone in the sintering box perform high-temperature curing treatment on the screen printing on the surface of the glass substrate, and the glass substrate passes through annealing zone one, annealing zone two, annealing zone three, annealing zone four and annealing zone five in sequence, thereby reducing the temperature of the glass substrate surface. This allows for screen printing of patterns on the glass substrate first, followed by curing and cutting, which can effectively improve the production efficiency of glass.

Detailed Implementation

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first embodiment of this utility model provides a glass substrate inkjet printing device. By first screen printing a pattern onto the glass substrate, and then curing the glass substrate in a sintering box 6, it can be ensured that the glass substrate will not crack after cutting.

[0024] Specifically, the loading machine 1 includes a directional conveyor frame 101 and storage racks 103 located on both sides of the directional conveyor frame 101. A four-sided grinder 2 is located at the right end of the directional conveyor frame, and an intelligent cleaning machine 3 is located at the right end of the four-sided grinder 2. A three-way conveyor 5 is located to the right of the intelligent cleaning machine 3. The three-way conveyor 5 includes two sets of bidirectional conveying components 501 arranged symmetrically and a linkage conveyor frame 502 located between the two sets of bidirectional conveying components 501. One set of bidirectional conveying components 501... The positions of 01 and the intelligent cleaning machine 3 are consistent in the left and right direction. The sintering box 6 is set at the left end of another set of bidirectional conveying components 501. The unloading machine 7 is set at the left end of the sintering box 6. The digital inkjet printer 4 is set at the right end of both sets of three-way conveyors 5. The internal space of the sintering box 6 is arranged from right to left as follows: preheating sintering zone 601, high temperature sintering zone 602, annealing zone one 603, annealing zone two 604, annealing zone three 605, annealing zone four 606, annealing zone five 607 and cooling zone 608.

[0025] With the above-described structure, the glass substrates are fed one by one to the four-sided grinder 2 by the loading machine 1. The glass substrates pass through the inside of the four-sided grinder 2 and the intelligent cleaning machine 3 in sequence. The four-sided grinder 2 grinds the glass substrates, while the intelligent cleaning machine 3 cleans the two ends of the glass substrates. Then, the substrates are screen-printed and cured by the three-way conveyor 5, the digital inkjet printer and the sintering box 6. This ensures that the glass substrates will not crack after cutting.

[0026] After the glass substrate moves into the preheating sintering zone 601, the ink on the glass substrate solidifies with the glass. The glass substrate takes 150 seconds to pass through the interior of the preheating sintering zone 601. Therefore, the compressor 609 delivers the gas in the gas storage tank 6010 into the interior of the preheating sintering zone 601. The upper and lower furnace bodies are equipped with compressed air convection auxiliary heating. The heating wires inside the preheating sintering zone 601 are designed in 13 groups, and the ceramic conveying rollers in the preheating sintering zone 601 are spaced 135 mm apart.

[0027] The glass substrate takes 150 seconds to pass through the interior of the high-temperature sintering zone 602. Therefore, the compressor 609 delivers the gas in the gas storage tank 6010 to the interior of the preheating sintering zone 601. The upper and lower furnace bodies are equipped with compressed air convection auxiliary heating. The heating wires inside the preheating sintering zone 601 are designed in 13 groups. The ceramic conveying rollers in the high-temperature sintering zone 602 have a spacing of 110 mm.

[0028] When the glass substrate passes through the interior of annealing zone 603, the basic temperature of the glass needs to be controlled to drop from 600℃ to 540℃, which takes 150s and has a cooling efficiency of 0.4 degrees / s. The ceramic conveying rollers are spaced 110mm apart. The upper and lower heating wires inside the sintering box 6 located in annealing zone 603 provide a constant annealing temperature field. The compressed air inside the sintering box 6 is cooled by convection, thereby ensuring that the glass cools down at a rate of 0.4 degrees / s.

[0029] When the glass substrate passes through the interior of annealing zone 2 604, the basic temperature of the glass needs to be controlled to drop from 540℃ to 520℃, which takes 150s and has a cooling efficiency of 0.13 degrees / s. The ceramic conveying rollers are spaced 120mm apart. The upper and lower heating wires inside the sintering box 6 located in annealing zone 2 604 provide a constant annealing temperature field. The compressed air inside the sintering box 6 is cooled by convection, thereby ensuring that the glass cools down at a rate of 0.13 degrees / s.

[0030] When the glass substrate passes through the interior of annealing zone 3 605, the basic temperature of the glass needs to be controlled to drop from 520℃ to 480℃, which takes 150s and has a cooling efficiency of 0.27 degrees / s. The ceramic conveying rollers are spaced 120mm apart. The upper and lower heating wires inside the sintering box 6 located in annealing zone 3 605 provide a constant annealing temperature field. The compressed air inside the sintering box 6 is cooled by convection, thereby ensuring that the glass cools down at a rate of 0.27 degrees / s.

[0031] When the glass substrate passes through the interior of annealing zone 4 606, the basic temperature of the glass needs to be controlled to drop from 480℃ to 420℃, which takes 150s and has a cooling efficiency of 0.4 degrees / s. The ceramic conveying rollers are spaced 150mm apart. The upper and lower heating wires inside the sintering box 6 located in annealing zone 4 606 provide a constant annealing temperature field. The compressed air inside the sintering box 6 is cooled by convection, thereby ensuring that the glass cools down at a rate of 0.4 degrees / s.

[0032] When the glass substrate passes through the interior of annealing zone 5 607, the basic temperature of the glass needs to be controlled to drop from 420℃ to 250℃, which takes 150s and has a cooling efficiency of 1.13 degrees / s. The ceramic conveying rollers are spaced 200mm apart. The upper and lower heating wires inside the sintering box 6 located in annealing zone 5 607 provide a constant annealing temperature field. The compressed air inside the sintering box 6 is cooled by convection, thereby ensuring that the glass cools down at a rate of 1.13 degrees / s.

[0033] After the glass substrate enters the cooling zone 608, the temperature of the glass substrate drops from 250°C to 60°C in 150 seconds, resulting in a reduction efficiency of 1.27°C / s.

[0034] Furthermore, the bidirectional conveying assembly 501 includes a roller conveyor frame 5011 and a belt conveyor frame 5012, which are arranged alternately from left to right. The conveying directions of the roller conveyor frame 5011 and the belt conveyor frame 5012 are perpendicular to each other. The belt conveyor frame 5012 is controlled by a lifting device, allowing it to move up and down. This enables the belt conveyor frame 5012 to move the glass substrate away from the upper surface of the roller conveyor frame 5011 and detach it from the conveyor frame.

[0035] It should be noted that the height of the roller conveyor 5011 is greater than the height of the belt conveyor 5012. Therefore, after the glass substrate initially moves to the position above the bidirectional conveyor assembly 501, the glass substrate will initially contact the surface of the roller conveyor 5011, so that the roller conveyor 5011 initially transfers the glass substrate into the digital inkjet printer 4.

[0036] Example 2

[0037] Please see Figure 1 and Figure 4 Based on Example 1, this example uses the compressor 609 and the air tank 6010 together to ensure stable heating or cooling of the glass substrate.

[0038] Specifically, the conveying direction of one set of roller conveyor frames 5011 is consistent with the conveying direction of the intelligent cleaning machine 3 and the digital inkjet printer 4. The conveying direction of the other set of roller conveyor frames 5011 is consistent with the conveying direction of the sintering box 6 and the other set of digital inkjet printer 4. The conveying direction of the belt conveyor frame 5012 is consistent with the conveying direction of the linkage conveyor frame 502. Compressors 609 and gas storage tanks 6010 are installed on the outside of the sintering box 6 at the positions of the preheating sintering zone 601, the high-temperature sintering zone 602 and the annealing zone. Each set of adjacent compressors 609 and gas storage tanks 6010 are connected to the interior of the corresponding preheating sintering zone 601, the high-temperature sintering zone 602 and the annealing zone, respectively. An intelligent robotic arm 102 is fixed on the top of each set of storage racks 103.

[0039] With the above-described structure, the compressed gas is delivered to the sintering chamber 6 by the compressor 609 and the gas storage tank 6010, ensuring that the glass substrate can be stably subjected to high-temperature treatment in the preheating sintering zone 601 and the high-temperature sintering zone 602, and ensuring that the glass substrate can be stably cooled in the annealing zone 1 603, annealing zone 2 604, annealing zone 3 605, annealing zone 4 606, annealing zone 5 607 and cooling zone 608. At the same time, the use of the intelligent robotic arm 102 ensures the stable transfer of the glass substrate.
