Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a photovoltaic glass coating device. Background Technology

[0002] In glass coating processes, the fitting precision between the coating roller and the first lower support roller directly affects the uniformity of the coating layer and the surface quality of the glass substrate. In traditional coating equipment, the coating roller and the first lower support roller typically employ an aligned design (i.e., parallel roller shafts and aligned contact lines). However, this design has the following technical drawbacks in actual production:

[0003] First: The extrusion of the glass head during feeding causes deformation of the coating roller surface and jamming: When the glass substrate enters the gap between the coating roller and the first lower support roller, the coating roller (the front end entering the gap) is prone to deformation due to local stress concentration because the glass travels in the opposite direction to the coating roller. This can even lead to jamming, especially in high-speed coating or large-size glass processing, where the incidence of such defects increases significantly.

[0004] Second: Defects such as color difference in the glass coating layer: Because the first lower roller is fixed in a vertical position and is on the same axis as the coating roller, the glass substrate must be kept horizontal before entering the roller gap. When the glass has a slight thickness difference, the pressure of the coating roller on the glass surface is uneven, resulting in uneven distribution of the coating layer, thus causing color difference, uneven coating thickness (too thick at the head), burrs, and regular surface defects.

[0005] Third: Reduced lifespan of coating rollers: Due to the collision and friction between the glass edges and the coating rollers, as well as the burrs from the previous edge grinding and chamfering processes, the lifespan of the coating rollers is reduced. Utility Model Content

[0006] The purpose of this invention is to provide a photovoltaic glass coating device that can alleviate the problems of deformation of the coating roller surface and material jamming caused by the extrusion of the glass head during feeding, thereby improving the coating quality and extending the service life of the coating roller.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] This utility model discloses a photovoltaic glass coating device, comprising: a frame; a transport mechanism mounted on the frame; the transport mechanism including a first transport roller, a conveyor belt, and a second transport roller, the first transport roller cooperating with a drive mechanism; the conveyor belt cooperating with the first transport roller and the second transport roller; a coating roller mounted on the frame and located above the conveyor belt; a first lower support roller mounted between the first transport roller and the second transport roller, the first lower support roller abutting against the lower surface of the conveyor belt and correspondingly arranged with respect to the coating roller; a second lower support roller and a steering roller, the second lower support roller and the steering roller being sequentially arranged between the first transport roller and the first lower support roller, the steering roller abutting against the upper surface of the conveyor belt and pressing down on the conveyor belt; wherein: a support plate is provided between the first lower support roller and the second lower support roller, the support plate being located above the steering roller; the diameter of the first lower support roller is smaller than the diameter of the coating roller, and the axis of the first lower support roller and the axis of the coating roller are staggered along the transport direction of the conveyor belt.

[0009] In some embodiments, the photovoltaic glass coating apparatus further includes an upper roller, which is mounted on the frame and is disposed corresponding to the second lower roller. The diameter of the upper roller is larger than the diameter of the second lower roller, and the axis of the upper roller and the axis of the second lower roller are staggered along the transport direction of the conveyor belt.

[0010] In some embodiments, the photovoltaic glass coating apparatus further includes a roller seat and an adjustment mechanism. The roller seat is adjustablely mounted on the frame and is used to support the first lower roller. The adjustment mechanism is mounted on the frame and connected to the roller seat, and is used to drive the roller seat to move to adjust the distance between the first lower roller and the coating roller.

[0011] In some specific embodiments, the adjustment mechanism includes: a vertical adjustment component connected to the idler roller seat, the vertical adjustment component being used to drive the idler roller seat to move in the vertical direction; and a horizontal adjustment component connected to the vertical adjustment component, the horizontal adjustment component being used to drive the vertical adjustment component to move in the horizontal direction.

[0012] In some more specific embodiments, the vertical adjustment assembly includes: a vertical drive source connected to the horizontal adjustment assembly; a lead screw connected to the vertical drive source; and a nut fitted to the lead screw and connected to the idler roller seat.

[0013] In some alternative embodiments, the horizontal adjustment assembly includes a horizontal drive source and a movable plate, the movable plate being movably mounted to the frame in a horizontal direction, the power output end of the horizontal drive source being connected to the movable plate to drive the movable plate to move in a horizontal direction, and the movable plate being used to mount the vertical drive source.

[0014] In some alternative embodiments, a first slide rail is provided on one of the idler roller seat and the movable plate, and a first slider is provided on the other of the idler roller seat and the movable plate. The first slide rail extends vertically, and the first slider is slidably mounted on the first slide rail.

[0015] In some alternative embodiments, a second slide rail is provided on one of the movable plate and the frame, and a second slider is provided on the other of the movable plate and the frame. The second slider extends horizontally and is slidably mounted on the second slide rail.

[0016] In some embodiments, the photovoltaic glass coating apparatus further includes a mounting base, which is adjustablely mounted on the frame in a vertical direction, and the tray is mounted on the mounting base.

[0017] In some specific embodiments, the mounting base is provided with a fixing hole, and the frame is provided with a fixing elongated hole. The fixing member passes through the fixing elongated hole and is connected to the fixing hole to fix the mounting base on the frame.

[0018] The beneficial effects of this photovoltaic glass coating device are as follows: In actual operation, the transport mechanism transports photovoltaic glass under the drive of a drive motor. Because a guide roller is installed between the first and second lower support rollers, the guide roller can press down on the conveyor belt, ensuring that the tail of the photovoltaic glass is close to the conveyor belt before entering the coating roller, thus forming a 2°-3° angle between the head of the photovoltaic glass and the transport plane. Simultaneously, the diameter of the first lower support roller is smaller than the diameter of the coating roller, and the axis of the first lower support roller is staggered from the axis of the coating roller along the transport direction of the conveyor belt. This allows the glass to enter the coating roller more smoothly, reducing the likelihood of defects such as jamming, deformation, and burrs. Therefore, the photovoltaic glass coating device can alleviate the problems of deformation of the coating roller surface and jamming caused by the pressure of the glass head during feeding, improving coating quality and extending the service life of the coating roller.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] This utility model discloses a photovoltaic glass coating device, referenced... Figure 1 and Figure 3 As shown, the photovoltaic glass coating apparatus of this embodiment includes a frame 1, a transport mechanism 2, a coating roller 3, a first lower support roller 4, a second lower support roller 5, and a steering roller 6. The transport mechanism 2 is mounted on the frame 1. The transport mechanism 2 includes a first transport roller 201, a conveyor belt 202, and a second transport roller 203. The first transport roller 201 cooperates with a drive mechanism, and the conveyor belt 202 cooperates with the first transport roller 201 and the second transport roller 203. The coating roller 3 is mounted on the frame 1 and located above the conveyor belt 202. The first lower support roller 4 is mounted on the first transport roller 201 and the second transport roller 203. Between 03, the first lower idler roller 4 abuts against the lower surface of the conveyor belt 202 and is correspondingly arranged with the coating roller 3. The second lower idler roller 5 and the guide roller 6 are arranged sequentially between the first transport roller 201 and the first lower idler roller 4. The guide roller 6 abuts against the upper surface of the conveyor belt 202 and presses down on the conveyor belt 202. A support plate 7 is provided between the first lower idler roller 4 and the second lower idler roller 5, and the support plate 7 is located above the guide roller 6. The diameter of the first lower idler roller 4 is smaller than the diameter of the coating roller 3, and the axis of the first lower idler roller 4 is staggered from the axis of the coating roller 3 along the transport direction of the conveyor belt 202. It can be understood that in actual operation, the transport mechanism 2 transports photovoltaic glass under the drive of the drive motor. Because the guide roller 6 is provided between the first lower idler roller 4 and the second lower idler roller 5, the guide roller 6 can press down on the conveyor belt 202 so that the tail of the photovoltaic glass is close to the conveyor belt 202 before entering the coating roller 3, thereby forming a 2°-3° angle between the head of the photovoltaic glass and the transport plane. Meanwhile, the diameter of the first lower roller 4 is smaller than that of the coating roller 3, and the axis of the first lower roller 4 is staggered from the axis of the coating roller 3 along the transport direction of the conveyor belt 202. This allows the photovoltaic glass to enter the coating roller 3 more smoothly, and it is less likely to have defects such as jamming, deformation and burrs. As a result, the photovoltaic glass coating device can alleviate the problem of deformation of the coating roller surface and jamming caused by the extrusion of the glass head, improve the coating quality and extend the service life of the coating roller 3.

[0030] refer to Figure 3 As shown, the photovoltaic glass coating device also includes an upper support roller 8, which is mounted on the frame 1 and positioned corresponding to the second lower support roller 5. The diameter of the upper support roller 8 is larger than the diameter of the second lower support roller 5, and the axis of the upper support roller 8 and the axis of the second lower support roller 5 are staggered along the transport direction of the conveyor belt 202. It is understood that the upper support roller 8 can press the photovoltaic glass downwards, ensuring stable transport of the photovoltaic glass when the guide roller 6 is in operation.

[0031] refer to Figure 2 and Figure 4As shown, the photovoltaic glass coating apparatus also includes a roller seat 9 and an adjustment mechanism. The roller seat 9 is adjustablely mounted on the frame 1 and supports the first lower roller 4. The adjustment mechanism is mounted on the frame 1 and connected to the roller seat 9, and drives the roller seat 9 to adjust the distance between the first lower roller 4 and the coating roller 3. It can be understood that by mounting the first lower roller 4 on the adjustable roller seat 9 and then adjusting the position of the roller seat 9 through the adjustment mechanism to adjust the distance between the first lower roller 4 and the coating roller 3, the photovoltaic glass coating apparatus of this embodiment can adapt to photovoltaic glass of various thicknesses and sizes. Furthermore, it can further alleviate the problems of deformation of the coating roller surface and material jamming caused by the extrusion of the glass head during feeding, improve coating quality, and extend the service life of the coating roller 3.

[0032] refer to Figure 1 and Figure 4 As shown, the adjustment mechanism includes a vertical adjustment component 10 and a horizontal adjustment component 11. The vertical adjustment component 10 is connected to the idler roller seat 9 and is used to drive the idler roller seat 9 to move in the vertical direction. The horizontal adjustment component 11 is connected to the vertical adjustment component 10 and is used to drive the vertical adjustment component 10 to move in the horizontal direction. It can be understood that in actual operation, the vertical adjustment component 10 can drive the idler roller seat 9 to move in the vertical direction, and the horizontal adjustment component 11 can drive both the idler roller seat 9 and the vertical adjustment component 10 to move in the horizontal direction. This two-way adjustment improves the adjustment accuracy of the first lower idler roller 4, thereby precisely adjusting the distance between the first lower idler roller 4 and the coating roller 3.

[0033] refer to Figure 4 As shown, the vertical adjustment assembly 10 includes a vertical drive source (not shown), a lead screw, a nut, and a roller seat 9. The vertical drive source is connected to the horizontal adjustment assembly 11, the lead screw is connected to the vertical drive source, and the nut is fitted to the lead screw and connected to the roller seat 9. It can be understood that in actual operation, after the vertical drive source is started, it can drive the lead screw to rotate. The rotation of the lead screw can drive the nut to move, thereby causing the roller seat 9 to move, thus driving the roller seat 9 to rise and fall. The transmission structure of the lead screw and nut ensures that the roller seat 9 can rise and fall stably, reducing the probability of the roller seat 9 becoming skewed. Furthermore, it enables precise control of the rise and fall of the roller seat 9, improving the adjustment accuracy of the first lower roller 4, thereby accurately adjusting the distance between the first lower roller 4 and the coating roller 3.

[0034] It should be further noted that the vertical drive source may include a drive motor and a reducer, or it may only include a drive motor or a rotary drive cylinder, depending on the actual needs. Of course, in other embodiments of this utility model, the vertical adjustment component 10 may be a structure such as an electric push rod or a cylinder that directly drives the roller seat 9 to rise and fall.

[0035] To improve motion stability, vertical adjustment components 10 and corresponding horizontal adjustment components 11 can be provided on both sides of the idler seat 9 along the axial direction of the first lower idler 4.

[0036] refer to Figures 2-4 As shown, the horizontal adjustment assembly 11 includes a horizontal drive source and a movable plate 1101. The movable plate 1101 is movably mounted on the frame 1 in the horizontal direction. The power output end of the horizontal drive source is connected to the movable plate 1101 to drive the movable plate 1101 to move in the horizontal direction. The movable plate 1101 is used to mount the vertical drive source. It can be understood that in actual operation, the horizontal drive source driving the movable plate 1101 to move can drive the vertical drive source to move, thereby causing the idler roller seat 9 to move in the horizontal direction, thus facilitating the adjustment of the idler roller seat 9.

[0037] refer to Figure 2 As shown, a first slide rail 12 is provided on the upper part of the movable plate 1101, and a first slider 13 is provided on the roller seat 9. The first slide rail 12 extends vertically, and the first slider 13 is slidably mounted on the first slide rail 12. In actual operation, when the nut drives the roller seat 9 to slide vertically, the first slider 13 slides relative to the first slide rail 12. The cooperation between the first slider 13 and the first slide rail 12 can restrict the movement direction of the roller seat 9, preventing the roller seat 9 from becoming skewed and jammed. Of course, in other embodiments of this utility model, the movable plate 1101 is provided with a first slider 13, the roller seat 9 is provided with a first slide rail 12, and the movable plate 1101 and the roller seat 9 can also be guided by other guiding structures.

[0038] refer to Figure 2 As shown, a second slide rail 14 is provided in the frame 1, and a second slider 15 is provided on the movable plate 1101. The second slider 15 extends horizontally and is slidably mounted on the second slide rail 14. In actual operation, when the horizontal drive source drives the movable plate 1101 to move horizontally, the second slider 15 slides relative to the second slide rail 14. The cooperation between the second slider 15 and the second slide rail 14 can restrict the movement direction of the movable plate 1101, preventing the movable plate 1101 from becoming skewed and jammed. Of course, in other embodiments of this utility model, the frame 1 is provided with a second slider 15, the movable plate 1101 is provided with a second slide rail 14, and the movable plate 1101 and the frame 1 can also be guided by other guiding structures.

[0039] Optional, see reference Figure 4As shown, the photovoltaic glass coating apparatus also includes a mounting base 16, which is vertically adjustable on the frame 1, and a support plate 7 is mounted on the mounting base 16. It is understood that by adjusting the position of the mounting base 16, the support plate 7 can be adjusted, thereby ensuring that the support plate 7 can stably support the photovoltaic glass.

[0040] Alternatively, the mounting base 16 has a fixing hole, and the frame 1 has a fixing elongated hole. A fastener passes through the fixing elongated hole and connects to the fixing hole to secure the mounting base 16 to the frame 1. Understandably, in actual operation, the fastener can be pulled out of the fixing hole, then repositioned within the fixing elongated hole, and finally re-engaged with the fixing hole. This allows for easy adjustment of the mounting base 16. The fastener can be a screw, a pin, or other structural form, depending on actual needs.
