Description

Technical Field

[0001] The present application relates to the field of photovoltaic processing technology, and in particular to a photovoltaic module, a gluing device and a photovoltaic module installation method. Background Art

[0002] In the photovoltaic industry, aluminum frames are generally used as frames of photovoltaic modules to protect the photovoltaic panels in the photovoltaic modules. During the photovoltaic module frame assembly process, sealant is injected into the mounting groove of the aluminum frame, and then the edge of the photovoltaic panel is inserted into the mounting groove, so as to bond and seal the aluminum frame and the photovoltaic panel.

[0003] In traditional photovoltaic modules, the aluminum frame will block the front of the photovoltaic panel. During the assembly process of the photovoltaic panel and the aluminum frame, the sealant will overflow to the front of the photovoltaic panel when squeezed by the photovoltaic panel. The aluminum frame and the overflowing sealant block the photovoltaic panel, reducing the lighting area of ​​the photovoltaic panel, which in turn affects the power generation efficiency of the photovoltaic panel. Summary of the invention

[0004] Based on this, it is necessary to provide a photovoltaic module, a sealing device and a photovoltaic module installation method, which can avoid the frame and sealant from blocking the photovoltaic panel and improve the power generation efficiency of the photovoltaic module.

[0005] In a first aspect, the present application provides a photovoltaic assembly, including a photovoltaic panel and a frame, wherein the photovoltaic panel and the frame are connected by a colloid, and the frame includes:

[0006] Main frame;

[0007] A trough body is arranged on the main frame, the trough body includes a lower trough wall and a trough bottom, the lower trough wall and the trough bottom surround a mounting trough, the colloid is arranged on the lower trough wall, the back of the photovoltaic panel is connected to the lower trough wall, the vertical surface of the photovoltaic panel is connected to the trough bottom, a card slot is arranged on the trough bottom, and the colloid can be inserted into the card slot when squeezed.

[0008] In one embodiment, one end of the lower groove wall away from the groove bottom extends out of the main frame, so that the colloid can be bonded to the outer side surface of the lower groove wall.

[0009] In a second aspect, the present application provides a glue applying device for applying glue to the photovoltaic module in the above embodiment, the glue applying device comprising:

[0010] A positioning jig, wherein the positioning jig is provided with a positioning groove, the positioning groove is used to accommodate the frame to be glued, and the frame is positioned in the positioning groove at a preset inclination angle;

[0011] A locking assembly is configured to limit the frame from being separated from the positioning groove.

[0012] In one embodiment, the glue applying device further comprises:

[0013] The mounting frame, the positioning fixture is detachably connected to the mounting frame, the positioning fixture is configured in several groups, and the positioning grooves of different forms are respectively arranged on the several groups of positioning fixtures.

[0014] In a third aspect, the present application provides a photovoltaic assembly installation method for installing the photovoltaic assembly in the above embodiment, the photovoltaic assembly installation method comprising:

[0015] Injecting colloid into the lower groove wall at one end of the groove of the mounting groove on the frame;

[0016] Insert the photovoltaic panel into the mounting groove so that the edge of the photovoltaic panel presses on the colloid, and then push the photovoltaic panel toward the bottom of the mounting groove so that the photovoltaic panel presses the colloid into the bottom of the mounting groove and squeezes the colloid out from the back of the photovoltaic panel.

[0017] In one of the embodiments, before gluing the lower groove wall at one end of the groove of the mounting groove on the frame, the relative position between the frame and the gluing head is adjusted so that the inner wall of the lower groove wall faces the glue outlet of the gluing head.

[0018] In one of the embodiments, the angle α between the inner wall surface of the lower groove wall and the plane perpendicular to the glue discharge direction of the glue head is set to 15°-60°.

[0019] In one of the embodiments, when applying glue to the lower groove wall, the thickness of the glue is gradually increased from one side close to the groove bottom to the other side.

[0020] In one of the embodiments, the angle between the glue outlet surface of the glue head and the inner wall surface of the lower groove wall is set to 0°-25°.

[0021] In one embodiment, after the colloid is squeezed out from the back side of the photovoltaic panel, the colloid on the back side of the photovoltaic panel is pressed toward the outer wall surface of the lower groove wall so that the colloid is adhered to the outer wall surface.

[0022] The photovoltaic assembly proposed in this application has the back of the photovoltaic panel supported on the lower groove wall, the facade of the photovoltaic panel connected to the bottom of the groove, and the frame does not block the front of the photovoltaic panel, so that the front of the photovoltaic panel can be completely exposed, which is conducive to improving the power generation efficiency of the photovoltaic panel. Furthermore, a card slot is provided on the bottom of the groove, and the colloid enters the card slot when squeezed, which is conducive to preventing the colloid from overflowing upward to the front of the photovoltaic panel to avoid blocking the photovoltaic panel, and is also conducive to improving the appearance of the photovoltaic panel. Moreover, a card connection structure is formed between the colloid and the groove body, which is conducive to preventing the colloid from detaching from the frame, thereby improving the firmness of the connection between the colloid and the photovoltaic panel and the frame.

[0023] The gluing device proposed in the present application, through the structural design of the positioning groove, makes the lower groove wall of the frame tilt upward at one end close to the groove opening, so that the colloid dripping vertically from the gluing head can drip directly onto the lower groove wall, avoiding the upper groove wall blocking the lower groove wall and causing the colloid to be unable to drip directly onto the lower groove wall. At the same time, the lower groove wall receives the colloid so that the colloid can stay on the lower groove wall.

[0024] The photovoltaic module installation method proposed in the present application injects colloid into the lower groove wall of the mounting groove on the frame and hits the position on the lower groove wall near the groove opening. When the photovoltaic panel is assembled with the frame, the photovoltaic panel is inserted into the mounting groove from the groove opening and pushes the colloid on the lower groove wall to move to the bottom of the groove, which is beneficial to control the overflow of the colloid to the front of the photovoltaic panel after passing through the bottom of the groove; and the colloid will overflow from the back of the photovoltaic panel due to being squeezed. Since the photovoltaic panel has a tendency to move toward the bottom of the groove, the amount of glue overflowing from the back of the photovoltaic panel is also relatively easy to control, thereby improving the continuity and uniformity of the overflow lines on the front and back of the photovoltaic module, thereby improving the sealing effect and appearance.

[0045] Referring to Figure 1, Figure 1 shows a schematic diagram of the partial structure of a photovoltaic module provided in an embodiment of the present application. The photovoltaic module includes a photovoltaic panel 2 and a frame 1. The four edges of the photovoltaic panel 2 are inserted into the frame 1, and the photovoltaic panel 2 is fixed by connecting the frame 1 to the frame. Among them, the photovoltaic panel 2 includes a stacked glass layer 21, a film layer 22 and a back plate layer 23. One side of the glass layer 21 is the front of the photovoltaic panel 2, and one side of the back plate layer 23 is the back of the photovoltaic panel 2. When the frame 1 and the photovoltaic panel 2 are assembled, a colloid 3 is injected between the frame 1 and the photovoltaic panel 2 for bonding and sealing. The colloid 3 generally uses a sealant. The structure of the frame 1 and the continuity and uniformity of the colloid 3 have an important influence on the performance of the photovoltaic module.

[0046] As shown in FIG. 2 , FIG. 2 shows a schematic diagram of the structure of a frame 1 provided in an embodiment of the present application. The frame 1 includes a main frame 11 and a slot 12, and the main frame 11 is used to connect with a frame (not shown in the figure). The slot 12 is arranged on the main frame 11, and the slot 12 includes a lower slot wall 121 and a slot bottom 122, and the lower slot wall 121 and the slot bottom 122 surround a mounting slot 120, and the colloid 3 is arranged on the lower slot wall 121, and the back of the photovoltaic panel 2 is connected to the lower slot wall 121, and the vertical surface of the photovoltaic panel 2 is connected to the slot bottom 122, and a card slot 1221 is arranged on the slot bottom 122, and the colloid 3 can be inserted into the card slot 1221 when squeezed.

[0047] The groove body 12 of the frame 1 is an L-shaped structure. When assembled with the photovoltaic panel 2, the back of the photovoltaic panel 2 is supported on the lower groove wall 121, and the vertical surface of the photovoltaic panel 2 is connected to the groove bottom 122. The frame 1 does not block the front of the photovoltaic panel 2, and the front of the photovoltaic panel 2 can be completely exposed, which is conducive to improving the power generation efficiency of the photovoltaic panel 2. Furthermore, a card slot 1221 is provided on the groove bottom 122. When the colloid 3 is squeezed, it enters the card slot 1221, which is conducive to preventing the colloid 3 from overflowing upward to the front of the photovoltaic panel 2, so as not to block the photovoltaic panel 2, and at the same time, it is also conducive to improving the appearance of the photovoltaic panel 2. Moreover, a card connection structure is formed between the colloid 3 and the groove body 12, which is conducive to preventing the colloid 3 from detaching from the frame, thereby improving the firmness of the connection between the colloid 3 and the photovoltaic panel 2 and the frame.

[0048] In one embodiment, the height of the groove bottom 122 is not higher than the front side of the photovoltaic panel 2 , thereby ensuring the flatness of the front side of the photovoltaic module.

[0049] Photovoltaic modules installed outdoors will inevitably be exposed to wind and sun for a long time, especially in some windy and dusty areas, which will cause dust accumulation on the photovoltaic modules. The dust accumulation on the photovoltaic modules will cause a serious reduction in power consumption and hot spot effect problems, so it is necessary to clean the surface of the photovoltaic modules. Flushing with water is a commonly used cleaning method, but many photovoltaic modules are installed at a small angle on the roof. During flushing, the mud and dust washed off the photovoltaic panel 2 will be blocked by the frame 1 and accumulate at the lower edge of the photovoltaic panel 2, forming a serious obstruction. By adopting the above-mentioned L-shaped frame 1, the upper surface of the frame 1 is lower than the photovoltaic panel 2, which will not block the mud and dust washed off the photovoltaic panel 2, so that the mud and dust can flow smoothly out of the photovoltaic module.

[0050] In one embodiment, as shown in FIG2 , an anti-skid pattern 1211 is provided on the inner wall of the lower groove wall 121 near one end of the groove to increase friction. When applying glue, the glue 3 is applied to the anti-skid pattern 1211 .

[0051] As shown in FIG1 , in order to further improve the firmness of the connection between the photovoltaic panel 2 and the frame 1, one end of the lower groove wall 121 away from the groove bottom 122 extends out of the main frame 11, so that the colloid 3 can be bonded to the outer side of the lower groove wall 121. A snap fit is also formed between the colloid 3 and the lower groove wall 121, further improving the firmness of the connection between the colloid 3 and the frame 1, and ensuring that the photovoltaic panel 2 is firmly installed on the frame 1.

[0052] The above-mentioned frame 1 is particularly suitable for the lower edge of the photovoltaic panel 2. The frame 1 applicable to the upper edge, left edge and right edge of the photovoltaic panel 2 generally does not form a barrier to mud, sand and dust. Therefore, in order to ensure the firmness of the installation of the photovoltaic panel 2, the frame 1 applicable to the upper edge, left edge and right edge of the photovoltaic panel 2 can adopt a structure with better wrapping. Specifically, as shown in Figure 3, Figure 3 shows a structural schematic diagram of another frame 1 provided in an embodiment of the present application. The frame 1 also includes an upper groove wall 123, and the upper groove wall 123, the groove bottom 122 and the lower groove wall 121 form a U-shaped installation groove 120. The photovoltaic panel 2 is inserted into the U-shaped installation groove 120, so that the upper groove wall 123 forms a pressure against the front of the photovoltaic panel 2, thereby ensuring better connection strength.

[0053] In the related art, when the frame 1 and the photovoltaic panel 2 are assembled, the frame 1 is generally placed horizontally with the notch of the mounting groove 120 facing upward, and the colloid 3 is vertically dripped onto the groove bottom 122 of the mounting groove 120. When the photovoltaic panel 2 is inserted into the mounting groove 120, the colloid 3 is squeezed so that the colloid 3 overflows from the front and back of the photovoltaic panel 2, forming a connection and seal between the photovoltaic panel 2 and the frame 1. For the frame 1 proposed in this embodiment, especially the L-shaped frame 1, the method of injecting the colloid 3 into the groove bottom 122 will cause serious unevenness of the front overflow line. Therefore, a method of injecting the colloid 3 into the lower groove wall 121 is proposed in this embodiment.

[0054] Adapted to this glue injection method, as shown in Figures 4 to 6, Figures 4 and 5 show a partial structural schematic diagram of a glue-spraying device 4 provided in an embodiment of the present application, and Figure 6 shows a schematic diagram of the working state of a glue-spraying head 41. This embodiment provides a glue-spraying device 4, which includes a glue-spraying head 41, a positioning fixture 42, and a locking assembly 43. The positioning fixture 42 is provided with a positioning groove 420, which is used to accommodate a frame 1 to be glued, and the frame 1 is positioned in the positioning groove 420 at a preset tilt angle. The locking assembly 43 is configured to limit the frame 1 from being separated from the positioning groove 420. By designing the structure of the positioning groove 420, the end of the lower groove wall 121 of the frame 1 close to the groove opening is tilted upward, and the colloid 3 dripping vertically from the glue head 41 can drip directly onto the lower groove wall 121, avoiding the upper groove wall 123 blocking the lower groove wall 121 and causing the colloid 3 to be unable to drip directly onto the lower groove wall 121. At the same time, the lower groove wall 121 receives the colloid 3 so that the colloid 3 can stay on the lower groove wall 121.

[0055] Specifically, the positioning groove 420 is set as a V-shaped groove, and the main frame body 11 of the frame 1 is stuck in the positioning groove 420. By designing the inclination angle of the groove wall of the V-shaped groove, the lower groove wall 121 of the installation groove 120 is in a position and angle suitable for receiving the drip glue.

[0056] Optionally, the glue-spraying device 4 further includes a mounting frame 44, and a positioning fixture 42 is detachably connected to the mounting frame 44. The positioning fixture 42 is configured in a plurality of groups, and a plurality of groups of positioning fixtures 42 are respectively provided with positioning grooves 420 of different forms. The positioning fixture 42 is detachably connected to the mounting frame 44 by a plurality of fasteners such as bolts or screws, and a suitable positioning fixture 42 can be selected according to the structural parameters of the frame 1 to be positioned.

[0057] Two sets of the above-mentioned positioning fixtures 42 can be installed on the mounting frame 44 to simultaneously position two frames 1 , thereby improving the gluing efficiency of the frames 1 .

[0058] In one embodiment, as shown in FIG. 5 , the positioning fixture 42 includes a plurality of positioning blocks 421, and the plurality of positioning blocks 421 are provided with positioning grooves 420 of the same shape, and the plurality of positioning blocks 421 are arranged at intervals along the length direction of the frame 1 to jointly support and position the frame 1. Among them, two positioning blocks 421 are respectively supported at the two ends of the frame 1, and the other positioning blocks 421 are supported at the middle position of the frame 1. Each group of positioning fixtures 42 is configured with two locking components 43, and the two locking components 43 are provided at the positioning blocks 421 at the two ends to lock the two ends of the frame 1.

[0059] Optionally, as shown in FIG4 , the locking assembly 43 includes a driving member 431 and a pressing plate 432, wherein the fixed end of the driving member 431 is disposed on the mounting frame 44, and the driving end of the driving member 431 is connected to the pressing plate 432 to drive the pressing plate 432 to approach or move away from the positioning groove 420. The pressing plate 432 can press the frame 1 in the positioning groove 420 under the drive of the driving member 431, fix the frame 1 in the positioning groove 420, and prevent the frame 1 from moving along its length direction in the positioning groove 420, thereby ensuring the accuracy of the glue application. In one embodiment, the driving member 431 is an oil cylinder or a pneumatic cylinder.

[0060] Specifically, the pressing plate 432 presses the groove bottom 122 of the frame 1 so that the main frame body 11 is pressed tightly against the groove wall of the positioning groove 420 , thereby clamping two opposite sides of the frame 1 to fix the frame 1 in the positioning groove 420 .

[0061] As shown in Figures 7 and 8, Figure 7 shows a flow chart of a photovoltaic module installation method provided in an embodiment of the present application, and Figure 8 shows a schematic diagram of the gluing position of the frame 1 provided in an embodiment of the present application. This embodiment also provides a photovoltaic module installation method, which includes:

[0062] S1: injecting the colloid 3 into the lower groove wall 121 at one end of the groove of the mounting groove 120 on the frame 1;

[0063] S2: Insert the photovoltaic panel 2 into the mounting groove 120 so that the edge of the photovoltaic panel 2 is pressed on the colloid 3, and then push the photovoltaic panel 2 toward the groove bottom 122 of the mounting groove 120, so that the photovoltaic panel 2 presses the colloid 3 into the groove bottom 122 of the mounting groove 120 and squeezes the colloid 3 out from the back side of the photovoltaic panel 2.

[0064] The photovoltaic module installation method provided in this embodiment injects the colloid 3 into the lower groove wall 121 of the mounting groove 120 on the frame 1, and hits the position on the lower groove wall 121 near the groove. When the photovoltaic panel 2 is assembled with the frame 1, the photovoltaic panel 2 is inserted into the mounting groove 120 from the groove, and pushes the colloid 3 on the lower groove wall 121 to move toward the groove bottom 122, which is beneficial to control the overflow of the colloid 3 to the front of the photovoltaic panel 2 after passing through the groove bottom 122; and the colloid 3 will overflow from the back of the photovoltaic panel 2 due to being squeezed. Since the photovoltaic panel 2 has a tendency to move toward the groove bottom 122, the amount of glue overflowing from the back of the photovoltaic panel 2 is also relatively easy to control, thereby improving the continuity and uniformity of the overflow lines on the front and back of the photovoltaic module, thereby improving the sealing effect and appearance.

[0065] Optionally, the colloid 3 printed on the lower groove wall 121 extends to both ends of the frame 1 along the length direction of the frame 1, thereby ensuring sufficient glue at the ends of the frame 1 and preventing glue shortage at the joints of the frame 1, thereby further ensuring sealing.

[0066] In one embodiment, as shown in Figure 9, the photovoltaic module installation method includes step S0: before gluing the lower groove wall 121 at one end of the groove of the installation groove 120 on the frame 1, adjust the relative position between the frame 1 and the gluing head 41 so that the lower groove wall 121 faces the glue outlet of the gluing head 41, so that the colloid 3 dripping vertically from the gluing head 41 can drip smoothly onto the lower groove wall 121.

[0067] Based on the aforementioned glue applying device 4, the frame 1 is placed in the positioning groove 420 on the positioning fixture 42, so that the lower groove wall 121 is tilted upward to face the glue applying head 41. For both the L-shaped frame 1 and the U-shaped frame 1, the angle of the positioning fixture 42 can be adjusted to expose the lower groove wall 121 to the glue applying head 41, so that the glue head dripping vertically from the glue applying head 41 can drip smoothly onto the lower groove wall 121.

[0068] In one embodiment, as shown in FIG6 , the angle α between the inner wall surface of the lower groove wall 121 and the plane perpendicular to the glue discharge direction of the glue head 41 is set to 15°-60°, and the angle α is preferably set to 45°. Generally, the glue head 41 discharges glue vertically downward, and the inner wall surface of the lower groove wall 121 is inclined. Within this angle range, it is suitable for receiving the colloid 3 and the colloid 3 is not easy to flow downward along the lower groove wall 121.

[0069] In one embodiment, when applying glue to the lower groove wall 121, the thickness of the colloid 3 is gradually increased from one side close to the groove bottom 122 of the mounting groove 120 to the other side. In other words, the thickness of the colloid 3 is larger at one end close to the groove, and when the photovoltaic panel 2 squeezes the colloid 3 toward the groove bottom 122, a sufficient amount of the colloid 3 can be ensured to overflow from the back of the photovoltaic panel 2.

[0070] In order to achieve the above-mentioned difference in the thickness of the colloid 3, please continue to refer to Figure 6. The angle between the glue outlet surface 411 of the glue head 41 and the inner wall surface of the lower groove wall 121 is set to 0°-25°, so that the distance between the lower groove wall 121 and the glue outlet surface 411 of the glue head 41 gradually increases from the side close to the groove bottom 122 to the side close to the groove opening, thereby making the thickness of the glue head hit by the glue head 41 on the lower wall surface gradually increase from the side close to the groove bottom 122 to the side close to the groove opening.

[0071] In one embodiment, the photovoltaic module installation method further includes step S3: after the colloid 3 is squeezed out from the back of the photovoltaic panel 2, the colloid 3 on the back of the photovoltaic panel 2 is squeezed toward the outer wall surface of the lower groove wall 121, so that the colloid 3 is adhered to the outer wall surface of the lower groove wall 121. In actual operation, a flat plate can be used to squeeze the colloid 3 on the back of the photovoltaic panel 2.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
