Description

Technical Field

[0001] This utility model relates to the technical field of insulating glass production equipment, and in particular to a coating device for insulating glass production. Background Technology

[0002] In fields such as building energy conservation, transportation, and high-end electronic displays, insulated glass has become one of the core basic materials due to its excellent heat insulation, sound insulation, and light transmission control performance. The coating process, as a key step in improving the optical performance (such as low emissivity, high light transmittance, and anti-glare) and functional attributes (such as self-cleaning and UV protection) of insulated glass, directly determines the final product quality and market competitiveness of the insulated glass. Therefore, the stability, clamping reliability, and coating uniformity of the insulated glass coating equipment, as the core equipment for realizing this process, have always been a key focus of industry technology research and development and equipment improvement.

[0003] The current mainstream coating equipment for insulating glass production still suffers from two major technological defects in practical industrial applications, which seriously restrict production efficiency and product yield. The specific problems are as follows: Firstly, traditional clamping structures suffer from the dual limitations of rigid contact and single-material design, making them prone to glass damage. Existing devices often use rigid clamping plates made of metal or hard plastic, driven by hydraulic or pneumatic cylinders to clamp and fix the glass. On one hand, due to the inherent micro-stress at the edges of insulated glass (residue from cutting and grinding during production), the point / line contact mode of rigid clamping easily causes localized stress concentration. When the clamping force control precision is insufficient, it can easily lead to glass edge breakage or the formation of irreversible stress marks on the glass surface. Such defects directly result in product scrap; according to industry statistics, the glass loss rate due to improper clamping can reach 3%-8%. On the other hand, traditional clamping surfaces are made of a single material (such as pure rubber or ordinary plastic), providing only basic anti-slip properties and lacking effective buffering and stress dispersion capabilities. During dynamic adjustments of the clamping force (such as when switching between different glass thicknesses), they cannot adapt to the brittle characteristics of the glass, further exacerbating the risk of glass damage.

[0004] Secondly, the glass displacement caused by airflow disturbance during the coating process directly affects the uniformity of the coating layer. Existing coating devices mostly employ high-pressure atomization spraying designs. As the nozzle moves along the glass surface during coating, it generates continuous airflow impact, especially during nozzle start-up, shutdown, and turning, where the airflow velocity can reach 5-8 m / s. Traditional clamping structures rely solely on mechanical force for fixation, offering weak resistance to airflow impact, easily leading to a micro-displacement of 0.1-0.5 mm in the insulating glass. Although this displacement is difficult to detect with the naked eye, it can cause problems such as superimposed coating, missed areas, or uneven thickness, resulting in optical performance deviations of the coated glass exceeding standard requirements. This, in turn, affects the performance in downstream applications, such as uneven light transmission in building curtain walls and poor visibility in automotive windshields.

[0005] Furthermore, while some existing devices attempt to alleviate displacement issues by increasing clamping force, this approach further amplifies the risk of glass damage caused by rigid clamping, creating a dilemma. Simultaneously, the lack of real-time monitoring and feedback mechanisms for clamping force prevents dynamic adjustment of clamping parameters based on glass specifications, resulting in poor adaptability and difficulty in meeting the diverse and customized production needs of current insulated glass. Therefore, developing a coating device that combines flexible buffer clamping with anti-airflow displacement fixing functions is crucial for addressing industry pain points and improving product quality. Utility Model Content

[0007] The technical solution adopted by this utility model includes a workbench, a mounting plate, a mounting box for placing the PLC control panel, a drive assembly, a clamping plate, a composite clamping layer, a micro suction cup, and a coating liquid spraying assembly.

[0024] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] like Figures 1-6 As shown, this embodiment provides a coating device for insulating glass production, including a workbench 1, a mounting plate 2, a mounting box 3 for placing a PLC control panel, a drive assembly 4, a clamping plate 5, a composite clamping layer 6, a micro suction cup 7, and a coating liquid spraying assembly 8. The mounting box 3 is an existing structure used to protect the PLC control panel, and a conventional one can be selected during use.

[0026] A polyurethane synchronous belt 9 is installed at the upper end of the workbench 1 for conveying insulating glass; A sliding groove is provided on the upper inner side of the mounting plate 2. An industrial camera 10 is mounted on one end of the mounting plate 2. The industrial camera 10 is electrically connected to the PLC control panel.

[0027] The mounting box 3 is fixedly installed at one end of the mounting plate 2; like Figure 3 and Figure 4 As shown, the driver component 4 includes: A square plate 401 is fixedly installed at both ends of the mounting plate 2. A square groove is opened at one end of the square plate 401, and a square rod 402 is inserted into the square groove. A first lead screw 403 is rotatably installed in the square groove, and the outer side of the first lead screw 403 is connected to the square rod 402. The first motor 404 is fixedly installed at one end of the square plate 401. The output end of the first motor 404 is fixedly connected to the first lead screw 403, and the first motor 404 is electrically connected to the PLC control panel. Guide rods 11 are inserted into both ends of the mounting plate 2. One end of the guide rod 11 is fixedly connected to the clamping plate 5, and one end of the clamping plate 5 is fixedly connected to the square rod 402. A miniature pressure sensor is installed inside one end of the clamping plate 5, and the miniature pressure sensor is electrically connected to the PLC control panel. During use, the PLC control panel identifies... The parameters of the insulating glass are sent to the first motor 404, which drives the first lead screw 403 inside the square plate 401 to rotate, causing the square rod 402 to move along the square groove, thereby pushing the clamping plate 5 closer to the edge of the insulating glass. The guide rods 11 at both ends of the mounting plate 2 are fixedly connected to the clamping plate 5 to ensure that the clamping plate 5 does not shift during movement, thus improving the adjustment accuracy. A miniature pressure sensor at one end of the clamping plate 5 detects the contact force between the composite clamping layer 6 and the edge of the glass in real time and feeds the data back to the PLC control panel. When the pressure reaches a preset threshold, the PLC control panel controls the first motor 404 to stop operating to avoid excessive clamping force causing the glass to break or insufficient clamping force causing displacement.

[0028] like Figure 5 As shown, the composite clamping layer 6 includes: The inner sensing layer 601 is fixedly installed at one end of the clamping plate 5. The inner sensing layer 601 is made of conductive silicone and has a thickness of 1.5mm. The middle buffer layer 602 is fixedly installed at one end of the inner sensing layer 601. The middle buffer layer 602 is made of porous silicone and has a thickness of 3mm. The outer wear-resistant layer 603 is fixedly installed at one end of the middle buffer layer 602. The outer wear-resistant layer 603 is made of fluororubber and has a thickness of 0.5mm. The micro suction cups 7 are linearly arrayed and installed at one end of the composite clamping layer 6. During use, the three layers of the composite clamping layer 6 work together: the inner sensing layer 601 transmits pressure signals to the micro pressure sensor; the middle buffer layer 602 absorbs the clamping impact force through micro-airbag deformation, reducing stress concentration; the outer wear-resistant layer 603 improves the wear resistance in contact with the insulating glass and avoids hard contact damage to the insulating glass; at the same time, the micro suction cups 7 are activated, adsorbing the surface of the insulating glass through negative pressure, forming a double fixation of "mechanical force + adsorption force" with the mechanical clamping, further resisting the airflow impact generated by the movement of the fan-shaped nozzle during the coating process, preventing the insulating glass from shifting. The negative pressure of the micro suction cups 7 is adjusted according to the thickness of the insulating glass, so that the micro suction cups 7 can stably adsorb the insulating glass.

[0029] like Figure 6 As shown, the coating liquid spraying assembly 8 is installed at one end of the mounting plate 2. The coating liquid spraying assembly 8 includes a second lead screw 801, a sliding rod 802, a sliding plate 803 with an internal cavity, a water pump 804, and a water tank 805. The second lead screw 801 is rotatably installed in the sliding groove. A second motor 12 is fixedly installed at one end of the mounting plate 2. The output end of the second motor 12 is fixedly connected to the second lead screw 801. The second motor 12 is electrically connected to the PLC control panel. One end of the sliding rod 802 is connected to the second lead screw 801, and the other end of the sliding rod 802 is fixedly connected to the sliding plate 803. A linearly distributed fan-shaped nozzle is fixedly installed at one end of the sliding plate 803. One end of the fan-shaped nozzle is connected to the cavity. The water pump 804 and the water tank 805 are both fixedly installed on the upper end of the mounting plate 2. One end of the water tank 805 is connected to the water pump 804 through a pipe. The inlet end of the water pump 804 is connected to the cavity via the water supply pipe 13. The water pump 804 is electrically connected to the PLC control panel. During use, a certain length is reserved at one end of the water supply pipe 13 to facilitate the movement of the sliding plate 803. During coating, the second motor 12 drives the second lead screw 801 in the sliding groove to rotate under the control of the PLC control panel, which drives the sliding rod 802 and the sliding plate 803 to move smoothly along the length of the insulating glass. At the same time, the PLC control panel controls the water pump 804 to start, drawing the coating liquid in the water storage tank 805 through the pipeline and sending it into the cavity of the sliding plate 803 through the water supply pipe 13. The linearly distributed fan-shaped nozzles at one end of the sliding plate 803 atomize and spray the coating liquid in the cavity evenly. With the movement of the sliding plate 803, the coating liquid is fully covered on the surface of the insulating glass.

[0030] Working principle: First, the polyurethane synchronous belt 9 on the upper end of the workbench 1 is started, which smoothly transports the insulating glass to be coated to the clamping area inside the mounting plate 2. The polyurethane synchronous belt 9 has a certain elasticity, which can reduce the vibration of the insulating glass during transportation and lay the foundation for subsequent precise clamping. The industrial camera 10 at one end of the mounting plate 2 takes real-time pictures of the insulating glass entering the clamping area and transmits the image information to the PLC control panel inside the mounting box 3. The PLC control panel quickly analyzes the glass parameters (such as length, width, and edge contour) through image recognition algorithms to determine the required clamping range and force threshold, realizing specification adaptation without manual intervention. According to the recognized insulating glass parameters, the PLC control panel sends control commands to the first motor 404 of the drive component 4 to move the clamping plates 5 on both sides. The miniature pressure sensor at one end of the clamping plate 5 detects the contact force between the composite clamping layer 6 and the edge of the insulating glass in real time and feeds the data back to the PLC control panel. When the pressure reaches the preset threshold (dynamically matched according to the glass thickness), the PLC control panel controls the first motor 404 to stop operating to avoid excessive clamping force causing glass breakage or insufficient clamping force causing displacement. After the clamping plate 5 is in place, the composite clamping layer 6 and the micro suction cup 7 work together to achieve stable fixation of the insulating glass. At the same time, the composite clamping layer 6 improves the buffering effect. The PLC control panel controls the start of the coating liquid spraying component 8 to carry out the coating process. After the coating is completed, the PLC control panel controls the following in sequence: the coating liquid spraying component 8 stops working, the micro suction cup 7 releases negative pressure, the first motor 404 reverses to drive the clamping plate 5 to reset, and the polyurethane synchronous belt 9 starts to transport the coated insulating glass to the next process.
