Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component manufacturing, in particular to a glue head for gluing a full-screen photovoltaic component. Background Art

[0002] With the development of the photovoltaic industry, photovoltaic frames without A-side and full-screen photovoltaic modules have been launched on the market. This means that the top of the photovoltaic frame is removed, so that the front of the entire photovoltaic module is not blocked by the photovoltaic frame. This can solve the problem of dust accumulation in the photovoltaic layer caused by the photovoltaic frame blocking, reduce the cleaning frequency, and improve the photoelectric conversion efficiency.

[0003] The glue head for the frame of traditional photovoltaic modules is usually beveled, and the glue head needs to be inserted into the U-shaped notch of the frame for glue application, and ensure that the glue head is perpendicular to the B side of the frame. However, the notch of the frame of full-screen photovoltaic modules is "L" shaped, and the traditional glue application method cannot meet the glue application needs of the frame of full-screen photovoltaic modules.

[0004] At present, the glue application on the frame of full-screen photovoltaic modules usually adopts the method of making the glue head perpendicular to the C side of the frame. Since the frame of full-screen photovoltaic modules has no A side to block, there are higher requirements for the overflow effect of the frame, and therefore there are also higher requirements for the glue type of the frame glue application, and it is necessary to ensure that the height and width of the glue type are as consistent as possible. However, traditional glue heads for frame glue application cannot meet this requirement. Utility Model Content

[0020] A transition cavity is provided in the transition piece, the mounting hole and the glue passage cavity are communicated with each other through the transition cavity, and the cavity diameter of the transition cavity is smaller than the hole diameter of the mounting hole.

[0021] In some embodiments, a flow guide is further included, and the flow guide is disposed between the transition piece and the hose;

[0025] The top wall connects the top edges of the two side walls and extends along the two side edges of the side walls to be connected with the two short sides of the hose.

[0026] In some embodiments, the distance between the two short sides of the glue passage cavity is greater than the cavity diameter of the transition cavity, and the distance between the two long sides of the glue passage cavity is smaller than the cavity diameter of the transition cavity.

[0027] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are:

[0041] See also Figure 1 A glue head for gluing a full-screen photovoltaic module according to an embodiment of the present application includes a mounting seat 1 and a glue hose 4 that are connected and communicated with each other.

[0042] The rubber hose 4 is a flat structure, and a rubber cavity 5 is formed inside. The rubber cavity 5 extends along the axial direction of the rubber hose 4 to penetrate the top surface of the rubber hose 4 to form a rubber inlet (not shown), and penetrates the bottom surface of the rubber hose 4 to form a rubber outlet 6. The bottom surface of the rubber hose 4 is horizontally arranged and perpendicular to the axial direction of the rubber hose 4.

[0043] A flow restriction port 7 is provided on one long side of the rubber tube 4, and the flow restriction port 7 is connected with the rubber passage cavity 5. The flow restriction port 7 extends from the bottom surface of one long side of the rubber tube 4 along the axial direction of the rubber tube 4 toward the rubber inlet, and the width of the flow restriction port 7 in the horizontal direction is equal to the width of the rubber passage cavity 5.

[0044] When applying glue, the bottom surface of the glue tube 4 is parallel to the glue application surface of the photovoltaic frame 100 and is located 1mm to 4mm above the glue application surface, so that the direction of the flow restriction port 7 is opposite to the glue application direction of the glue head. Figure 2 As shown, the glue direction of the glue head is parallel to the long side of the photovoltaic frame 100. After the glue flows out through the glue outlet 6, the width and height of the glue after the glue is discharged can be kept consistent due to the restrictions of the flow direction, the glue outlet 6 and the flow restriction 7. At the same time, by accurately controlling the flow, shape and direction of the glue, waste can be avoided, the amount of glue used can be saved, the production cost can be reduced, and the efficiency of the production line can be improved. The direction of the glue head is as shown in FIG. Figure 2 As shown by arrow a.

[0045] In some embodiments, the flow restriction opening 7 is rectangular. Specifically, the height of the flow restriction opening 7 in the axial direction of the hose 4 is 1 mm to 6 mm.

[0046] Alternatively, the flow restriction opening 7 is in any one of a trapezoidal shape, a triangular shape, a semicircular shape, and an inverted "U" shape, and the height of the flow restriction opening 7 in the axial direction of the rubber tube 4 is 1 mm to 6 mm. This application does not make any specific limitation on this.

[0047] In some embodiments, the long side of the cross section of the hose 4 is a straight line structure, and the short side is an arc structure convex outward.

[0048] In some embodiments, the mounting seat 1 includes a main body 11 and a mounting boss 12 .

[0049] Specifically, the main body 11 is cylindrical in structure, and a mounting hole (not shown) is provided in the main body 11. The mounting boss 12 is arranged around the outer periphery of the main body 11 and is located at one end of the main body 11 away from the rubber tube 4, and is used to further fasten the rubber head through a fastener (not shown) when the rubber head is installed.

[0050] In some embodiments, the diameter of the mounting hole gradually increases from close to the rubber tube 4 to away from the rubber tube 4. That is, the mounting hole is an inverted truncated cone structure, which facilitates the assembly of the glue head and the gun head of the glue machine.

[0051] In some embodiments, a transition piece 2 is disposed between the mounting seat 1 and the hose 4 .

[0052] Specifically, the transition piece 2 is a cylindrical structure. A transition cavity (not shown) is provided in the transition piece 2, and the mounting hole and the glue-passing cavity 5 are connected through the transition cavity, and the cavity diameter of the transition cavity is smaller than the hole diameter of the mounting hole. The distance between the two short sides of the glue-passing cavity 5 is larger than the cavity diameter of the transition cavity, and the distance between the two long sides of the glue-passing cavity 5 is smaller than the cavity diameter of the transition cavity.

[0053] In some embodiments, a flow guide 3 is provided between the transition piece 2 and the rubber hose 4. A flow guide cavity (not shown) is provided in the flow guide 3, and the transition cavity is connected with the rubber passage cavity 5 through the flow guide cavity. The flow guide 3 is provided with a feed port (not shown) and a discharge port (not shown) at both ends of the axial direction, respectively. The shape of the feed port is adapted to the cross-sectional shape of the transition cavity, and the shape of the discharge port is adapted to the cross-sectional shape of the rubber passage cavity 5.

[0054] Specifically, the flow guide 3 includes a top wall 31 and two side walls 32 arranged opposite to each other. The bottom edges of the two side walls 32 are arranged horizontally and are connected to the two long sides of the hose 4 in a one-to-one manner, and the two side edges of the side walls 32 gradually converge toward the middle from the bottom end to the top end of the side walls 32. The top wall 31 connects the top edges of the two side walls 32 and extends along the two side edges of the side walls 32 to connect to the two short sides of the hose 4.

[0055] Based on the same inventive concept, the present application also proposes a glue spraying machine, including the above-mentioned glue head, which is installed on the gun head of the glue spraying machine. When in use, the glue flows out through the glue hose 4 to the glue outlet 6. In operation, the glue outlet 6 of the glue hose 4 is located 1mm to 4mm above the glue spraying surface of the photovoltaic frame 100, and the bottom surface is parallel to the glue spraying surface, and the direction of the flow restriction port 7 is opposite to the glue spraying direction of the glue head.

[0056] During the automatic gluing process, the glue sticks to the gluing surface, and is restricted by the traveling direction, the glue outlet 6 and the flow limiting port 7. The width and height of the glue after the glue is discharged are consistent, and it extends along the length direction of the photovoltaic frame 100. When assembling the frame, the module is inserted into the "L"-shaped groove of the photovoltaic frame 100, and the "L"-shaped groove of the photovoltaic frame 100 is filled with glue. Since the width and height of the glue after the glue is discharged are consistent, a uniform and tight glue layer is formed between the module and the photovoltaic frame 100, thereby improving the bonding strength and sealing between the module and the frame.

[0057] Finally, it should be noted that the above are only preferred embodiments of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
