[0038] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The first aspect of this utility model provides a coating device 10 for coating glass with a liquid, which ensures the uniformity of the coating. It is understood that the glass can be rolled glass. The following refers to… Figures 1 to 5 The following describes the coating apparatus 10 according to an embodiment of this application. Specifically, the coating apparatus 10 includes a coating section 100 and a drive assembly 200. The coating section 100 can be single or multiple; this embodiment illustrates the application with multiple coating sections 100 as an example.

[0040] Reference Figures 1 to 4The coating section 100 is used to coat glass with a liquid. The coating section 100 includes a base 110 and a coating head 120, which are connected to each other. Specifically, the coating head 120 can be detachably connected to the base 110. This facilitates the replacement of the coating head 120 to adapt to different application scenarios. The specific structural configuration of the coating section 100 can be determined according to actual conditions. A drive assembly 200 is used to drive the coating section 100 to move. It is understood that the drive assembly 200 is connected to the base 110. The drive assembly 200 includes a first drive part and a second drive part. The first drive part is used to drive the coating head 120 to press against the glass. For example, the coating head 120 and the glass are arranged vertically in a Z-direction, and the first drive part can drive the coating head 120 to press against the glass vertically in a Z-direction. The second drive part is used to drive the coating head 120 to scrape the glass.

[0041] It is understood that in some embodiments, the first driving unit may use a cylinder to drive the coating head 120 by air pressure. In other embodiments, the first driving unit may also use a hydraulic cylinder to drive the coating head 120 by hydraulic pressure. In other embodiments, the first driving unit may also use an electric motor to drive the coating head 120. The specific configuration of the first driving unit can be determined according to the actual situation. This application embodiment uses a cylinder-driven first driving unit as an example for explanation. The driving method of the second driving unit may be the same as or different from that of the first driving unit. This application embodiment uses a cylinder-driven second driving unit as an example for explanation.

[0042] It should be noted that during the process of the coating head 120 pressing against the glass, the coating head 120 can undergo elastic deformation, which can reduce the impact of the coating device 10 on the glass and prevent collisions. During the process of the coating head 120 scraping the glass, the coating head 120 can be tilted relative to the glass, so that the coating head 120 can evenly coat the glass and ensure the coating effect.

[0043] In the technical solution of this utility model, the coating device 10 includes a coating section 100 and a driving assembly 200. The coating section 100 includes a base 110 and a coating head 120 connected to each other. The driving assembly 200 is connected to the base 110 and includes a first driving part and a second driving part. In related technologies, coating rolled glass manually is prone to uneven coating due to the operator's coating ability, resulting in poor laser drilling effect and difficulty in ensuring glass quality. In this solution, the first driving part can drive the coating head 120 to press against the glass, and the second driving part can drive the coating head 120 to scrape the glass. During the process of the coating head 120 pressing against the glass, the coating head 120 can undergo elastic deformation, which can reduce the impact of the coating device 10 on the glass. During the glass coating process using the coating head 120, the coating head 120 can be tilted relative to the glass to apply the coating. Specifically, the end of the coating head 120 that first contacts the glass guides the liquid to spread evenly, and the subsequent parts of the coating head 120 follow sequentially. The gravitational force generated by its tilt assists the liquid flow, breaking the tendency to converge due to surface tension, thus achieving uniform coating of the glass, improving the laser drilling effect, and enhancing glass quality. Furthermore, this solution can achieve overall glass coating operation through the drive assembly 200, making the overall operation convenient and quick, improving coating accuracy and efficiency, and meeting the needs of high-speed production lines.

[0044] Reference Figures 1 to 4 The specific configuration of the coating head 120 is described below. In some embodiments, the coating head 120 includes a flow divider 121 and a coating cotton. The flow divider 121 is used to divide the liquid, and the coating cotton is used to contact the glass to achieve coating. The coating cotton is arranged to at least partially wrap around the flow divider 121, and the specific wrapping arrangement of the coating cotton can be determined according to the actual situation. The flow divider 121 includes an inlet hole 1211 and an outlet hole 1212. Liquid can flow into the flow divider 121 through the inlet hole 1211 and flow to the coating cotton through the outlet hole 1212. That is, the outlet hole 1212 can guide the liquid flowing into the inlet hole 1211 to the coating cotton to realize the coating operation on the glass and ensure the coating effect.

[0045] Reference Figure 4The specific configuration of the flow divider 121 is described below. In some embodiments, the flow divider 121 includes a plurality of liquid outlet holes 1212, which can be arranged at intervals. That is, the liquid flowing through the flow divider 121 can be dispersed into multiple fine liquid streams by the multiple liquid outlet holes 1212 before flowing to the coating cotton. This can effectively refine the liquid particles, reduce the influence of surface tension of the liquid, and allow the liquid to spread evenly on the glass surface, achieving uniform coating and ensuring the coating effect. It should be noted that the diameter of the liquid outlet hole 1212 can be smaller than the diameter of the liquid inlet hole 1211, that is, it can achieve a stable liquid supply from the liquid inlet hole 1211 to the liquid outlet hole 1212. The diameter of the liquid outlet hole 1212 is D, where D satisfies: 0.5mm≤D≤3mm. For example, D can be 0.5mm, 0.7mm, 0.85mm, 1mm, 1.5mm, 1.9mm, 2mm, 2.5mm, 2.7mm, or 3mm, etc. Furthermore, D satisfies: 0.5mm≤D≤1mm, and the specific aperture setting of the liquid outlet hole 1212 can be determined according to the actual situation.

[0046] The specific tilting configuration of the coating head 120 is described below. In some embodiments, the first driving unit is used to drive the coating head 120 to press against the glass vertically (Z), see reference. Figure 3 The orientation, i.e., the first driving unit can drive the coating head 120 to press against the glass in the vertical direction. During the process of coating the glass with the coating head 120, the tilt angle of the coating head 120 relative to the glass is A, where A satisfies: 5° ≤ A ≤ 30°. For example, A can be 5°, 8°, 10°, 15°, 20°, or 30°, etc. Further, A satisfies 5° ≤ A ≤ 10°. The coating head 120 of this solution adopts the above-mentioned tilt setting, which can effectively improve the coating effect and ensure the quality of glass processing.

[0047] Reference Figures 1 to 3 The specific structural configuration of the coating head 120 is described below. In some embodiments, the coating head 120 includes a fixing member 122, which is detachably connected to the diverter 121. Specifically, the fixing member 122 can be bolted or screwed to the diverter 121, or it can be snapped onto the diverter 121. The coating cotton can be disposed between the diverter 121 and the fixing member 122. The fixing member 122 can press the coating cotton tightly to the diverter 121, which can effectively improve the stability of the assembly connection between the coating cotton and the diverter 121.

[0048] Reference Figure 5The specific movement configuration of the coating head 120 is described below. In some embodiments, the first driving unit can drive the coating head 120 to press against the glass along the vertical Z direction. The coating device 10 includes a displacement assembly 300, which is used to drive the coating part 100 to move. Specifically, the displacement assembly 300 includes a first displacement part 310. To facilitate the description and understanding of the specific movement direction of the coating part 100, a first direction X is defined, which is perpendicular to the vertical Z direction. The first displacement part 310 can drive the coating part 100 to move relative to the glass along the first direction X, referring to... Figure 5 The orientation, specifically the first direction X, can point to the left or right. The displacement component 300 in this solution can move the glass along the first direction X, enabling liquid coating operations to be performed on multiple locations of the glass according to actual working conditions, thus meeting various liquid coating scenarios.

[0049] Reference Figure 5 The specific movement configuration of the coating section 100 is described below. In some embodiments, the displacement component 300 is used to drive the coating section 100 to move. Specifically, the displacement component 300 includes a second displacement section 320. To facilitate the description and understanding of the specific movement direction of the coating section 100, a second direction Y is defined. The second direction Y is perpendicular to the vertical direction Z and intersects with the first direction X. Further, the second direction Y can be perpendicular to the first direction X, or it can be at other non-perpendicular tilt angles. The second displacement section 320 is used to drive the coating section 100 to move relative to the glass along the second direction Y, referring to... Figure 5 The second direction, Y, can point up or down, while the vertical direction, Z, can point forward or backward. The displacement component 300 in this solution can move the glass along the second direction Y, enabling liquid coating operations to be performed on multiple locations on the glass according to actual working conditions, thus meeting more liquid coating scenarios.

[0050] Reference Figure 5 The specific motion configuration of the first displacement unit 310 is described below. In some embodiments, the first displacement unit 310 includes a first slider 311 and a first slide rail 312, which cooperate with each other. The first slider 311 can be connected to the base 110, and the first slider 311 can slide along the first direction X on the first slide rail 312, that is, the first slider 311 can drive the coating unit 100 to move along the first direction X. This solution can change the arrangement position of the coating unit 100 to meet the coating requirements of glass under different working conditions and improve coating efficiency.

[0051] Reference Figure 5The specific motion configuration of the second displacement unit 320 is described below. In some embodiments, the second displacement unit 320 includes a second slider 321 and a second slide rail 322, which cooperate with each other. The second slider 321 can be connected to the base 110, and the second slider 321 can slide along the second direction Y, that is, the second slider 321 can drive the coating unit 100 to move along the second direction Y. This solution can change the arrangement position of the coating unit 100 to meet the coating requirements of glass under different working conditions and improve coating efficiency.

[0052] Reference Figures 1 to 3 In some embodiments, the end of the diverter 121 in the coating section 100 can be arc-shaped. This increases the contact area between the coating head 120 and the glass when the coating cotton wraps around the diverter 121 during the coating operation, improving the coating effect and ensuring the uniformity of the glass coating. In other embodiments, the coating section 100 includes a solenoid valve and a dispensing valve. The solenoid valve controls the opening and closing of the gas passage, and the gas precisely controls the coating amount through the dispensing valve, accurately outputting the coating liquid. The coating cotton can be made of PVA material, which has excellent liquid-holding properties, ensuring both the coating amount and uniformity.

[0053] A second aspect of this utility model provides a production line for processing glass. The production line includes the coating device 10 and the drilling device described in the above embodiment. It is understood that the coating device 10 can apply liquid to the drilling location on the glass, and the drilling device can perform drilling operations on the glass. The coating head 120 of this solution can be tilted relative to the glass to apply liquid. That is, the end of the coating head 120 that first contacts the glass can guide the liquid to spread evenly, and the subsequent parts of the coating head 120 follow sequentially. The gravitational force generated by its tilt can assist the liquid flow, breaking the tendency of liquid surface tension to converge, achieving uniform coating of the glass, improving the laser drilling effect of the glass, improving glass quality, and ensuring glass processing efficiency.

[0054] The applicant discovered the following defects in the existing production line: First, the coverage of the coating position in the traditional coating process is insufficient, with actual deviations generally exceeding ±3cm, resulting in a laser drilling pass rate of only 72%-78%; second, adjusting the coating position is time-consuming, requiring 28-35 minutes for a single position change, causing a loss of 15%-20% of effective production time per shift; third, manual operation accounts for too high a proportion, with labor costs in the coating process accounting for more than 65%, and it is difficult to adapt to the needs of high-speed production lines. In a specific embodiment of this application, a coating device 10 is provided at the front end of the drilling device. The coating device 10 can coat the drilling position of the glass with liquid, and the amount of liquid coated in a single operation can be the same. The coating device 10 can be driven by a motor, positioned and centered by a cylinder, and the amount of liquid coated in a single operation is controlled by a solenoid valve. The coating head 120 is driven by a cylinder for automatic coating, which can improve the continuity of laser drilling production and adapt to the production rhythm of the connected equipment. This solution, through a dual positioning mechanism and centering system, achieves a coating accuracy of ±0.5mm, covering the entire glass surface and increasing the drilling pass rate from 78% to 92%. Employing a modular quick-change design, coupled with metric hexagonal tools and a measuring tape for positioning, it reduces changeover time to 8-15 minutes, increases equipment utilization by 22%, and constructs a fully automated coating system (95% automation rate) through servo drive and PLC intelligent control. Furthermore, adjustable coating components can be designed to support rapid switching between more than five glass specifications without hardware replacement, meeting the diverse production needs of the photovoltaic industry.

[0055] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
