Description

Technical Field

[0001] This utility model relates to the field of glass processing, and in particular to a glass drying device. Background Technology

[0002] The core principle of glass drying technology in related fields is to use the heat generated by an electrically energized heating wire (furnace wire) to heat the printed glass, thereby achieving drying by evaporating moisture. It mainly consists of the following steps: 1. Preheating stage: After printing, the glass enters the infrared dryer and is first preheated at a low temperature. This stage is mainly to allow the solvent on the surface of the ink to evaporate slowly, so as to avoid the surface from drying rapidly due to sudden high temperature, while the internal solvent cannot be discharged and forms bubbles or pinholes.

[0003] 2. Heating and curing stage: As the temperature inside the infrared dryer rises, a large amount of solvent in the ink evaporates, and at the same time, the film-forming substances (such as resin, pigment, etc.) begin to undergo chemical reactions (such as cross-linking and polymerization). This stage is the core of drying. Through continuous heating, the film-forming substances are transformed from a dispersed state into a continuous and hard solid film, while enhancing the adhesion to the glass surface.

[0004] 3. Cooling and Shaping Stage: After curing, the glass enters the cooling zone, and the temperature gradually decreases to near room temperature. This stage can prevent stress cracking of the glass or the cured ink layer due to sudden cooling, ensuring the stable shaping of the ink film layer and ultimately forming a firm, wear-resistant, and weather-resistant printing effect.

[0005] Because infrared dryers have limited heating depth and moderate drying speed, and because B-pillar glass usually has two layers of ink printing, the drying effect after being dried by infrared dryers is poor, and the second layer of ink printing often fails to dry completely. Utility Model Content

[0006] Therefore, it is necessary to provide a glass drying apparatus that can rapidly evaporate ink contaminants while ensuring the drying effect.

[0007] A glass drying apparatus, comprising: A conveyor for carrying glass to be dried and conveying the glass to a drying station located upstream of the glass in the direction of movement; A laser generator, which is used to generate a laser beam; A laser shaping device is provided at the drying station to receive a laser beam emitted by the laser generator and to shape the laser beam to form a drying laser, which is used to dry the glass. A robotic arm is connected to the laser shaping device, and the robotic arm is capable of moving the laser shaping device.

[0008] In one embodiment, the glass drying apparatus includes a first blower configured to output a jet of air, the outlet of the first blower facing the area where the drying laser intersects with the glass.

[0009] In one embodiment, the robotic arm can drive the laser shaper and the first blower to move synchronously.

[0010] In one embodiment, the robotic arm is provided with a mounting base, and the laser shaper and the first blower are both mounted on the mounting base.

[0011] In one embodiment, the glass drying apparatus includes a second air blower disposed at the drying station, with the air outlet of the second air blower facing the glass, for blowing away the volatiles generated when the drying laser dries the glass.

[0012] In one embodiment, a cooling station is also formed on the conveyor, the cooling station being formed downstream of the drying station, the cooling station being provided with a cooling mechanism for cooling the dried glass.

[0013] In one embodiment, the cooling mechanism includes a cooling fan with its outlet facing the glass at the cooling station.

[0014] In one embodiment, the cooling fans include a plurality of cooling fans, and the plurality of cooling fans are spaced apart along the direction of movement of the glass.

[0015] In one embodiment, the conveying member includes a conveying drive and a plurality of conveying rollers, the plurality of conveying rollers being spaced apart, and the conveying drive being connected to the plurality of conveying rollers for driving the plurality of conveying rollers to rotate.

[0016] In one embodiment, the glass drying apparatus further includes a control module connected to the laser generator and the laser shaper.

[0017] In the above scheme, glass can be transported to the drying station by setting up a conveyor. A laser generator is set up to generate a laser beam, and a laser shaper is set up to receive the laser beam emitted by the laser generator and shape the laser beam to form a drying laser that meets the requirements for sintering ink contaminants. A robotic arm can be set up to move the laser shaper so that the drying laser can dry the glass. The drying laser energy after being shaped by the laser shaper is concentrated, which can raise the temperature of the drying area instantly, which can quickly evaporate ink contaminants and ensure that the drying laser accurately acts on the ink contaminants.

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] Please see Figure 1This application relates to a glass drying apparatus 10, including a frame 100, a conveyor 200, a laser generator 300, a laser shaper 400, and a robotic arm 500. The conveyor 200 is mounted on the frame 100, and the laser generator 300 is mounted on one side of the frame 100. The robotic arm 500 is capable of moving the laser shaper 400.

[0024] The conveyor 200 carries the glass to be dried and transports it to the drying station. It should be noted that glass feeding can be done manually or automatically by the robotic arm 500. The drying station is located upstream in the direction of glass movement. For example, the drying station is positioned near the inlet of the conveyor 200.

[0025] A laser generator 300 generates a laser beam, providing the energy source for the entire drying and sintering process. A laser shaper 400 is located at the drying station and receives the laser beam emitted by the laser generator 300, shaping the laser beam to form a drying laser used to dry the glass. The laser shaper 400 shapes the laser beam so that the shape, size, etc., of the drying laser beam meets the requirements for sintering ink contaminants. For example, the ink contaminant is an alcohol-based ester substance in the ink.

[0026] It should be noted that the principle of laser drying is to use the high energy density of the drying laser to precisely and efficiently heat the ink contaminants on the glass surface, causing the solvent in the ink contaminants to evaporate or solidify, thereby completing the drying of the glass.

[0027] By setting up a conveyor 200, glass can be transported to the drying station. By setting up a laser generator 300, which generates a laser beam, and a laser shaper 400, which receives the laser beam emitted by the laser generator 300 and shapes the laser beam to form a drying laser that meets the requirements for sintering ink contaminants. By setting up a robotic arm 500, the laser shaper 400 can be moved so that the drying laser can dry the glass. The drying laser energy after shaping by the laser shaper 400 is concentrated, which can instantly raise the temperature of the drying area, quickly evaporate ink contaminants, and ensure that the drying laser accurately acts on the ink contaminants. By adjusting the power and irradiation time of the drying laser, the heat penetration depth can be precisely controlled to ensure the drying effect.

[0028] Please see Figure 1According to some embodiments of this application, optionally, the glass drying apparatus 10 includes a first blowing element configured to output a jet of air, the outlet of the first blowing element facing the intersection area of ​​the drying laser and the glass. Exemplarily, the first blowing element is a jet generator, the air inlet of which is connected to an external airflow generator, for example, a hair dryer.

[0029] The first air blower directs a jet of air towards the intersection of the drying laser and the glass, enabling airflow regulation in the drying area. This helps to aid in heat dissipation and remove volatiles generated during the laser drying process. It should be noted that the first air blower generates a high-speed jet, making it significantly more powerful than a typical fan.

[0030] Please see Figure 1 According to some embodiments of this application, optionally, the robotic arm 500 can drive the laser shaper 400 and the first blower to move synchronously. Specifically, the robotic arm 500 is provided with a mounting base 510, and the laser shaper 400 and the first blower are both mounted on the mounting base 510. This allows the first blower to immediately act on the intersection area between the drying laser and the glass while the drying laser is drying the glass, quickly cleaning up the volatiles generated during the drying laser's drying of the glass, minimizing interference between the drying laser and the volatiles, and effectively improving drying efficiency. It should be noted that the mounting base 510 is located at the end of the robotic arm 500, and the mounting base 510 faces the conveyor 200. The first blower... Figure 1 It is not shown in the text.

[0031] Please see Figure 1 According to some embodiments of this application, optionally, the glass drying apparatus 10 includes a second blowing element 600, which is disposed at the drying station. The air outlet of the second blowing element 600 faces the glass to form an airflow to blow away volatiles generated during the laser drying of the glass. Specifically, the second blowing element 600 is disposed on one side of the conveyor 200. Exemplarily, the second blowing element 600 is a fan. Exemplarily, the second blowing element 600 may also be a jet generator.

[0032] By setting a second blowing component 600, the volatiles generated during the drying of laser-dried glass can be blown away to avoid the volatiles affecting the drying effect or remaining on the surface of the equipment and workpiece.

[0033] Please see Figure 1 According to some embodiments of this application, optionally, a cooling station is also formed on the conveyor 200, which is downstream of the drying station. The cooling station is equipped with a cooling mechanism for cooling the dried glass. The cooling station is located near the outlet of the conveyor 200.

[0034] In this embodiment, the cooling mechanism includes a cooling fan 700, the air outlet of which faces the glass on the cooling station. The cooling fan 700 is located on one side of the conveyor 200. In other embodiments, the cooling mechanism may also employ water cooling.

[0035] By setting up a cooling fan 700, the dried glass can be cooled, which can quickly lower the glass temperature, ensure the smooth progress of subsequent processes, and at the same time guarantee the performance and quality of the glass.

[0036] Please see Figure 1 According to some embodiments of this application, optionally, a plurality of cooling fans 700 are included, and the plurality of cooling fans 700 are spaced apart along the moving direction of the glass. In this embodiment, the number of cooling fans 700 is two. In other embodiments, the number of cooling fans 700 may be three, four, five or even more.

[0037] By setting up multiple cooling fans 700, the glass can be cooled down more quickly.

[0038] Please see Figure 1 According to some embodiments of this application, optionally, the conveying component 200 includes a conveying drive component 210 and a plurality of conveying rollers 220, the plurality of conveying rollers 220 being spaced apart, and the conveying drive component 210 being connected to the plurality of conveying rollers 220 for driving the plurality of conveying rollers 220 to rotate. Exemplarily, the conveying rollers 220 in the drying station are ceramic rollers, while the conveying rollers 220 in other areas are ordinary rubber rollers. It should be noted that ceramic rollers have high strength, high toughness, and good wear resistance, and also have strong chemical stability, resisting the erosion of various chemical substances.

[0039] Please see Figure 1 According to some embodiments of this application, optionally, a control module is also included. The control module is connected to the laser generator 300 and the laser shaper 400, and can precisely control the heat penetration depth by adjusting the power and irradiation time of the drying laser. The control module can also control the operating status of the robotic arm 500, and can control the first and second air blowers 600 to blow away volatiles generated during the drying laser drying of the glass. The control module can also control the cooling fan 700 to cool the dried glass. The control module can also control the conveying drive 210 to drive the rotation of multiple conveying rollers 220.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
