Description

Technical Field

[0001] The utility model belongs to a photovoltaic production device, and in particular relates to a photovoltaic glass glue coating device. Background Art

[0002] The application publication number CN117324198A discloses a method for gluing the edges of photovoltaic glass. No proper fixing measures are taken at the middle gluing position. When the glass itself is deformed (the glass is very thin) or vibrates, the gluing effect will be affected. In addition, the first conveying mechanism and the second conveying mechanism designed in the front and back are arranged alternately and staggered at intervals so as not to interfere with each other. In this way, when the incoming glass is lifted and transported to the gluing position by the first conveying mechanism, the suspended widths on both sides of the glass will be inconsistent, which will cause the glass to have a certain deformation and affect the accuracy of the gluing. In addition, the lifting and adjusting blocks and rollers used in the two conveying mechanisms are designed to achieve the lifting and lowering of the adsorption tray. However, the rollers and the lifting and adjusting blocks are in contact with each other without any restrictions in the vertical direction, which is not conducive to the prevention and control of vibration and other situations.

[0025] The utility model provides a photovoltaic glass glue coating device, such as Figure 1-Figure 8 As shown, it mainly includes a frame 1, a conveying mechanism arranged horizontally on the frame 1, and a gluing mechanism 2 arranged longitudinally in the middle of the frame 1. The conveying mechanism includes a first conveying mechanism 3a and a second conveying mechanism 3b, which are arranged at the front and rear sides of the gluing mechanism 2 and are each composed of a plurality of conveying belts arranged longitudinally side by side. Figure 1 As shown, the first conveying mechanism 3a and the second conveying mechanism 3b each have three conveying belts, and two of them are located on the same route horizontally, and the conveying belts in the first conveying mechanism 3a and the conveying belts in the second conveying mechanism 3b operate independently. Figure 2 As shown, the gluing mechanism 2 has a pair of gluing heads 21a, 21b that can move longitudinally. The conveying mechanism also includes: a plurality of vacuum conveyors 4 arranged longitudinally side by side below the gluing mechanism 2. Figure 2 There are also three vacuum conveyors 4, which are respectively located between the head and tail of the corresponding three conveyor belts of the front and rear conveyor mechanisms, so as to form three synchronous conveyor lines with the conveyor belts of the first and second conveyor mechanisms 3a and 3b. The vacuum conveyor 4 has a vacuum adsorption surface that adsorbs and supports the photovoltaic glass and can convey the photovoltaic glass.

[0026] The specific structure of each vacuum conveyor 4 is as follows Figure 3As shown, they all include a vacuum suction table 41, a vacuum belt 42 wound on the vacuum suction table 41 and provided with suction holes 44 on the surface, and a vacuum machine for vacuuming the upper surface of the vacuum belt 42. The vacuum machine can be composed of a vacuum chamber 43 connected to the suction holes 44 built into the vacuum suction table 41 and an external blower (not shown in the figure) connected to the vacuum chamber 43 through a pipeline. The upper surface of the vacuum belt 42 forms a vacuum suction surface, and by driving the vacuum belt 42 to rotate, the photovoltaic glass located on its upper surface can be driven forward, and the glass on its upper surface can be firmly sucked by vacuuming. Therefore, even if the glass itself has slight unevenness and deformation, it will be firmly sucked by the vacuum conveyor 4 during the glue coating process to avoid vibration and other factors affecting the glue coating quality. Furthermore, the three conveyor belts are arranged symmetrically in the center, and the spacing between the two outermost conveyor belts is designed to meet the minimum width specification of the glass products. The inner side spacing of the two outermost vacuum conveyors also matches the conveyor belts, while the outer side spacing of the two outermost vacuum conveyors is designed to meet the maximum width specification of the glass products. This makes it possible to accommodate glass coatings of different sizes. The glass coating of CN117324198A is supported by a conveying mechanism, but the conveying mechanism and the conveying mechanism are staggered in design, and therefore cannot meet the requirements of glass coatings of different sizes.

[0027] A conveying channel 5 is formed between adjacent conveying belts of the first conveying mechanism 3a and adjacent conveying belts of the second conveying mechanism 3b. Figure 1 , Figure 4 There are two transport channels 5, which are located between the three conveying lines. The front and back of the horizontal transport channels are connected by a passage gap in the middle. Each transport channel 5 is provided with a transport mechanism 6 that can transport photovoltaic glass between the first conveying mechanism 3a, the vacuum conveyor 4, and the second conveying mechanism 3b.

[0028] like Figure 4-Figure 6As shown, the transport mechanism 6 includes a lateral translation mechanism, a lifting mechanism and an adsorption transport plate 67. The lateral translation mechanism 61 includes a first guide rail 61 arranged transversely in the transport channel 5, a first base 62 arranged on the first guide rail 61, and a lateral driving device 63 driving the base to translate forward and backward on the first guide rail 61. The lateral driving device 63 can adopt a gear rack transmission mechanism, which can drive the first base 62 to slide from the first conveying mechanism 3a to the second conveying mechanism 3b on the first guide rail 61. The lifting mechanism is arranged on the first base 62, including a first screw motor 64 arranged transversely, a slider rail assembly 65 connected to the first screw motor 64, a connecting rod 66 with one end hinged on the slider rail assembly 65 and the other end hinged on the bottom of the adsorption transport plate 67, and a lifting guide column 68 vertically arranged between the base and the adsorption transport plate 67. The slider rail assembly 65 is composed of a slide rail fixed on the first base 62 and a slider matched with the slide rail, and the slider is driven by the first screw motor 64. When the first screw motor 64 rotates forward and reverse, it can drive the slider on the slider rail assembly 65 to move forward and backward along the rail, so that the connecting rod 66 can be propped up or down, and then drive the adsorption conveying plate 67 at its upper end to move up or down, and at the same time, the lifting guide column 68 plays the role of lifting and lowering guide. The maximum lifting height of the adsorption conveying plate 67 should be greater than the height of the upper surface of the conveyor belt. According to the length of the adsorption conveying plate 67, multiple groups of slider rail assemblies 65, connecting rods 66 and lifting guide columns 68 can be set, and the slider rail assemblies 65 are connected by connecting rods 70, and the same first screw motor 64 drives one of the slider rail assemblies 65 to drive the remaining slider rail assemblies 65 to move in linkage, so that the adsorption conveying plate 67 can be lifted and lowered. Vacuum adsorption holes 69 are distributed on the adsorption conveying plate 67, and a vacuum machine for vacuuming is connected to the outside through the vacuum channel. The vacuum machine is not shown in the figure.

[0029] like Figure 5 As shown, the two groups of conveying mechanisms 6 have a total of four adsorption conveying plates 67, wherein two adsorption conveying plates 67 located in different conveying channels 5 operate synchronously to form a group of conveying mechanisms 6. Preferably, Figure 5 The first and third adsorption conveying plates 67a from the inside to the outside constitute one group of conveying mechanisms 6, and the second and fourth adsorption conveying plates 67b constitute another group of conveying mechanisms 6. Each group of conveying mechanisms 6 can operate independently, and the efficiency can be improved by alternating front and back operations.

[0030] When the suction conveying plate 67 is raised to a high position, its surface is flush with the surface of the vacuum conveyor 4. A passage interval is formed between adjacent conveyors 4 to allow the conveying mechanism 6 to pass through so as not to interfere with the forward and backward movement of the suction conveying plate 67.

[0031] like Figure 4 , Figure 7 As shown, a plurality of lifting and guiding mechanisms 7 are provided on both outer sides of the first conveying mechanism 3a. Figure 4 There are three pairs of lifting guide mechanisms 7 of the first conveying mechanism 3a. Each lifting guide mechanism 7 includes a second base 71 arranged on the frame 1, a second screw motor 72 longitudinally arranged on the second base 71, a roller bracket 73 driven to rise and fall by the second screw motor 72, and a plurality of lifting rollers 74 arranged on the roller bracket 73. Each lifting guide mechanism 7 is independently controlled, and the lifting rollers 74 can be driven to rise and fall by the second screw motor 72 to support the edges of the glass on both sides.

[0032] like Figure 1 As shown, a pair of first detection cameras 8a for detecting the state of the front process of the incoming glass are respectively provided on both sides of the front end of the frame 1. A pair of second detection cameras 8b for detecting the glue coating state of the glass are respectively provided on both sides of the rear end of the frame 1.

[0033] like Figure 2 , Figure 4 As shown, the first conveying mechanism 3a is also provided with a positioning mechanism, including a front stopper wheel mechanism disposed at the front and rear ends of the first conveying mechanism 3a, and a rear stopper wheel mechanism ( Figure 2 , Figure 4 Only a pair of rear blocking wheel mechanisms 91 are shown, and the front blocking wheel mechanism is not shown, which has been disclosed in the CN117324198A patent and will not be repeated here) and several side blocking wheel mechanisms 92 ( Figure 4 Two pairs of side blocking wheel mechanisms are shown in FIG. Figure 8 As shown, each side stop wheel mechanism includes a second guide rail 921 arranged laterally, a longitudinal clamping mechanism 922 slidably arranged on the second guide rail 921, and a side stop wheel 923 driven for longitudinal translation by the longitudinal clamping mechanism 922. The position of the side stop wheel 923 in the length direction of the glass can be adjusted by lateral translation on the second guide rail 921, and the longitudinal clamping mechanism can also use a screw motor combined with a guide rail and a slider to drive the side stop wheel 923 to clamp the two sides of the glass in the longitudinal direction.

[0034] The above is the photovoltaic glass glue coating device of the utility model, and its working method is as follows:

[0035] A. A piece of photovoltaic glass is used as the current glass and is conveyed by the conveyor belt of the first conveying mechanism 3a into the photovoltaic glass gluing device. When the front end of the current glass enters the first conveying mechanism 3a, the first detection camera 8a can check the two coating vertex angles of the front end of the current glass. When the rear end of the current glass enters the first conveying mechanism 3a, the first detection camera 8a can check the two coating vertex angles of the rear end of the current glass. If it is detected that the previous process of the current glass is unqualified, the gluing process is not performed, and the conveying mechanism 6 directly conveys the current glass to the second conveying mechanism 3b.

[0036] B. When the current glass completely enters the first conveying mechanism 3a, the glass can be clamped and positioned by the front stop wheel mechanism, the raised rear stop wheel mechanism and the stop wheels of the side stop wheel mechanism. After positioning, one of the transport mechanisms 6 in the first conveying mechanism 3a serves as the current transport mechanism 6 to push the current glass upward off the conveying belt of the first conveying mechanism 3a, and the lifting and guiding mechanisms 7 on both sides are simultaneously lifted to lift the suspended areas on both sides of the current glass.

[0037] C. The current transport mechanism 6 absorbs the current glass and transports it forward. When the front short side of the current glass is directly below the glue coating mechanism 2, it pauses, and then the front short side of the current photovoltaic glass is supported by the vacuum conveyor 4.

[0038] D. The front short side of the current glass is coated with glue by the glue coating mechanism 2. Since the front short side of the current glass is adsorbed and fixed by the vacuum conveyor 4 during the entire process of coating the front short side, the front short side of the current glass will not vibrate, thereby ensuring the quality of the coating.

[0039] like Fig. 9 As shown, the method of gluing the front short side of the current glass by the gluing mechanism 2 is as follows: the two gluing heads 21a and 21b of the gluing mechanism 2 are located at the same starting position of the short side, wherein the gluing head 21a on the outside is located outside the gluing starting point of the short side, and the gluing head 21b on the inside is just at the gluing starting point of the short side. After the gluing starts, the gluing head 21b on the inside moves longitudinally toward the other end of the short side of the glass to apply glue to the short side. When the gluing head 21b on the inside moves to the gluing end point at the other end of the short side, it stops moving and stops gluing. When the gluing head 21b on the inside is applying glue to the short side, the other gluing head 21a on the outside should move to the gluing starting point of the short side.

[0040] E. After the front short side is glued, the current transport mechanism 6 and the vacuum conveyor 4 simultaneously adsorb the current glass and convey it to the second conveying mechanism 3b. During the conveying process, the gluing mechanism 2 applies glue to the long sides of the current glass. At this time, during the entire long side gluing process, the two side edges of the current photovoltaic glass are always adsorbed and supported by the vacuum conveyor 4 to drive and move, and there is also a lifting and guiding mechanism 7 to support it from the rear, so that the long side will not vibrate during the gluing process, thereby ensuring the gluing quality.

[0041] like Fig. 9As shown, the method for the gluing mechanism 2 to apply glue to the two long sides of the current glass is: after completing the gluing of the front short side, the two gluing heads 21a and 21b are respectively located at the gluing starting position and the gluing ending position of the front short side, that is, the two gluing heads 21a and 21b are both located at the gluing starting position of the long sides on both sides, and the two gluing heads 21a and 21b do not move but apply glue, and the glue is applied to the long sides on both sides through the forward movement of the current glass.

[0042] F. When the short side of the rear end of the current glass is transported to the bottom of the gluing mechanism, the current transport mechanism 6 and the vacuum conveyor 4 stop driving the current glass forward, and the gluing mechanism then applies glue to the short side of the rear end of the current glass. During the entire gluing process of the short side of the rear end, the short side of the rear end of the current glass is also adsorbed and fixed by the vacuum conveyor 4. Therefore, the short side of the rear end of the current glass will not vibrate, thereby ensuring the quality of gluing.

[0043] like Fig. 9 As shown, the method of gluing the short side of the current glass by the gluing mechanism is as follows: the gluing head 21b that originally applied glue to the short side of the front end continues to move longitudinally toward the other end of the short side of the rear end, and applies glue to the short side of the rear end during the movement until it is connected to the end position of the other long side of the gluing. In this process, the other gluing head 21a moves outward to avoid. Compared with the gluing method in the CN117324198A patent, the above-mentioned gluing method has only overlapping gluing points at the four vertices, while the latter has one more overlapping gluing point in the middle of the two short sides.

[0044] G. After the glue coating on the short side of the rear end is completed, the current transport mechanism 6 drives the current glass to continue to be transported to the second transport mechanism 3b. When the current glass has completely entered the second transport mechanism 3b, the current transport mechanism 6 drops the current glass onto the conveyor belt of the second transport mechanism 3b, and the conveyor belt of the second transport mechanism 3b then transports the glued current glass forward. During the transmission process, the second detection camera sequentially detects the two glued vertices at the front end, the two glued long sides, and the two glued vertices at the rear end. If there is any abnormality in the glue coating, a corresponding alarm can be issued.

[0045] After placing the current glass onto the conveyor belt of the second conveyor mechanism 3b, the current transport mechanism 6 quickly returns to the first conveyor mechanism 3a to wait for new incoming photovoltaic glass.

[0046] In the above step E, as the current glass moves forward, the next incoming photovoltaic glass as the new current glass begins to perform the above steps A and B. In the new step A, the three lifting and guiding mechanisms are successively lowered in the order of separation from the current glass so as not to block the new current glass, so that the new current glass can be smoothly transferred to the conveyor belt of the first conveying mechanism 3a. When the new current glass is positioned, another conveying mechanism 6 waiting in the first conveying mechanism 3a is used as the new current conveying mechanism to participate in the above steps C to H.

[0047] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
