[0001] The present application relates to the technical field of glue dispensing, in particular to a glue dispensing head and a glue dispensing device. BACKGROUND

[0002] Generally, the solar photovoltaic industry uses aluminum frames as the frames of solar cell modules to protect the laminated plates in the modules. For heterojunction cell modules, sealing glue needs to be injected into the mounting groove of the frame during the framing process of the heterojunction cell module.

[0003] During glue dispensing, the glue adheres to only one side surface (C surface) of the frame due to the influence of the inclined surface of the glue dispensing head, and the glue overflows to the other side surface (A surface) after being extruded. Generally, the mounting groove is like a U-shaped structure that clamps the edge of the glass, and the glue needs to be on both sides of the U-shaped structure to effectively prevent water vapor from penetrating.

[0004] At present, the photovoltaic module is supplemented with glue (silicone) on the A surface, and a part of the silicone is injected into the overflow groove through the hole on the A surface. Since the silicone is sticky, the flowability deviates over time, which causes the silicone to not accurately fall into the overflow groove.

[0005] During actual measurement, the amount of glue in each part of the mounting groove is different, which causes the sealing position of the mounting groove to be different, resulting in different distances between the sealing result and the edge of the frame. In the place where the glue is less, the sealing is poor, and water vapor easily penetrates, which affects the sealing effect. INVENTION CONTENTS

[0040] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0041] ​​​​​In addition, if there are these terms "first", "second", these terms are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one feature. In the description of the present application, if the term "a plurality of" appears, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In the present application, unless otherwise explicitly specified and limited, if the first feature is described as "on" or "below" the second feature and the like, it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the second feature, or only indicate that the first feature is higher than the second feature in horizontal height. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the second feature, or only indicate that the first feature is lower than the second feature in horizontal height.

[0044] It should be noted that if an element is referred to as "fixed to" or "provided on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.

[0045] It can be understood that at present, in the process of assembling the heterojunction battery assembly, it is necessary to inject sealant into the mounting groove of the frame. When the glue is injected, due to the influence of the inclined surface of the glue head, the glue is only attached to one side surface (C surface) of the frame, and the glue is extruded to the other side surface (A surface). Generally, the mounting groove, like a U-shaped, clamps the edge of the glass, and the glue needs to be on both sides of the U-shaped to effectively prevent water vapor from entering.

[0046] At present, the photovoltaic module is supplemented with glue (silicone) on the A surface, and a part of the silicone is injected into the overflow groove through the A surface opening. Since the silicone is sticky, the flowability deviates over time, causing the silicone to not accurately fall into the overflow groove portion. In the actual measurement process, the amount of glue in each part of the installation groove is different, which in turn causes the sealing position of the installation groove to be different, resulting in different distances between the sealed edge and the frame edge. In the area with less glue, the sealing is poor, and water vapor easily penetrates, affecting the sealing effect.

[0047] To this end, referring to Figures 1 to 3 The application provides a novel glue head 100. Figure 1 The schematic view of the glue head 100 of an embodiment of the application from one perspective, Figure 2 The schematic view of the glue head 100 from another perspective, Figure 1 The perspective view of the glue head 100. Figure 3 The perspective view of the glue head 100. Figure 1 The perspective view of the glue head 100.

[0048] The glue head 100 is applied to a glue injection device (not shown) and is used to inject glue 300 into an installation groove 210 of a to-be-glued part 200. The edge of a to-be-installed part 400 (not shown) is arranged in the installation groove 210, and the two side surfaces of the to-be-installed part 400 can be in contact with the installation groove 210 of the to-be-installed part 400 through the glue 300, thereby achieving a sealed connection between the to-be-glued part 200 and the to-be-installed part 400 and ensuring high sealing performance at the connection between the to-be-glued part 200 and the to-be-installed part 400.

[0049] In the application, injecting the glue 300 into the installation groove 210 of the to-be-glued part 200 is referred to as glue injection. In the following description of the injection of the glue 300 into the installation groove 210 by the glue head 100, glue injection is sometimes used for description.

[0050] Optionally, the glue 300 is silicone, which has good adhesion and can well achieve the sealing between the to-be-glued part 200 and the to-be-installed part 400. Of course, in other embodiments of the application, the glue 300 can also be other types of glue that can play a sealing role.

[0051] In this embodiment, the to-be-glued part 200 is a frame of a photovoltaic module, and the to-be-installed part 400 is tempered glass of the photovoltaic module. Generally, the edge of the tempered glass of the photovoltaic module is installed in the frame. After the glue 300 is injected into the frame, the frame and the tempered glass are sealed and connected through the glue 300, thereby ensuring the effective sealing of the photovoltaic module and preventing water vapor from entering the inside of the photovoltaic module, so as to ensure the service life and power generation efficiency of the photovoltaic module.

[0052] Of course, in other embodiments of the present application, the to-be-glued member 200 can also be other structures or components that need to be glued and sealed, and the to-be-installed member 400 can also be other components that need to be installed to the to-be-glued member 200.

[0053] The present application only takes the to-be-glued member 200 as the frame of the photovoltaic module and the to-be-installed member 400 as the tempered glass of the photovoltaic module as an example for description, and in the following description of the structure of the glue head 100, the to-be-glued member 200 is replaced by the frame of the photovoltaic module and the to-be-installed member 400 is replaced by the tempered glass of the photovoltaic module.

[0054] To better illustrate the structure of the glue head 100, the structure of the to-be-glued member 200 is introduced first. Referring to Figures 4 to 7 , Figure 4 To Figure 1 the schematic view of the glue head 100 and the to-be-glued member 200 cooperating in one perspective, Figure 5 To Figure 4 the schematic view of the glue head 100 and the to-be-glued member 200 cooperating in another perspective, Figure 6 To Figure 5 the side view of the glue head 100 and the to-be-glued member 200 cooperating, Figure 7 To Figure 6 the perspective view of the glue head 100 and the to-be-glued member 200 cooperating. The to-be-glued member 200 is arranged in a strip shape.

[0055] The to-be-glued member 200 has a recessed installation groove 210, and the installation groove 210 has a first surface 211 and a second surface 212 arranged opposite to each other, as shown in Figures 4 to 7 When the glue head 100 glues to the installation groove 210, the first surface 211 and the second surface 212 are glued respectively. After the to-be-installed member 400 is installed to the installation groove 210, the two side surfaces of the to-be-installed member 400 are sealed and contacted with the first surface 211 and the second surface 212 through the glue 300, so as to ensure the sealing performance between the to-be-glued member 200 and the to-be-installed member 400.

[0056] In addition, the installation groove 210 is also provided with a glue overflow groove 213, and the glue overflow groove 213 is recessed on the first surface 211. The glue 300 can overflow from the glue overflow groove 213 only after the glue 300 is injected into the glue overflow groove 213 and gradually fills the glue overflow groove 213. In this way, the glue overflow groove 213 can accommodate more glue 300 and prevent too much glue 300 from overflowing.

[0057] When the surface of the component to be installed 400 contacts the first surface 211, the adhesive 300 overflowing from the adhesive overflow groove 213 can contact the surface of the component to be installed 400, ensuring the seal between the component to be installed 400 and the component to be glued 200. At the same time, it can also prevent excessive adhesive 300 from entering the mounting groove 210, reducing adhesive 300 waste while ensuring the seal.

[0058] The mounting groove 210 also has a third surface 214, which is the bottom surface of the mounting groove 210 and connects the first surface 211 and the second surface 212. When the dispensing head 100 injects the adhesive 300 into the first surface 211 and the second surface 212, the adhesive 300 has good fluidity and can flow from the first surface 211 and the second surface 212 to the third surface 214.

[0059] After the component to be installed 400 is installed into the mounting groove 210, the surface of the component to be installed 400 is pressed against the first surface 211 of the component to be glued 200 and squeezed into the mounting groove 210, and then pressed against the second surface 212 of the component to be glued 200, until the bottom of the component to be installed 400 touches the third surface 214 of the component to be glued 200, at which point the component to be installed 400 stops moving. At this time, the first surface 211, the second surface 212, and the third surface 214 all have adhesive 300 in contact with the surface of the component to be installed 400.

[0060] After the colloid 300 cures, the colloid 300 on the first surface 211, the colloid 300 on the second surface 212, and the colloid 300 on the third surface 214 can completely seal the part to be glued 200 and the part to be installed 400. The mounting groove 210 of the part to be glued 200 is completely sealed, and water vapor cannot enter, thus ensuring the sealing between the part to be installed 400 and the part to be glued 200.

[0061] The directions of this application are up, down, left, right, front, and back. Figure 1 and Figure 4 Using the directions shown as a reference, the vertical direction of the dispensing head 100 represents the height direction, top-to-bottom direction, and extension direction; the horizontal direction of the dispensing head 100 represents the width direction; and the front-to-back direction of the dispensing head 100 represents the thickness direction. The mounting groove 210 is recessed along the height direction, and the first surface 211 and the second surface 212 are positioned opposite each other along the thickness direction. The part to be glued 200 extends along the width direction. The height direction, width direction, and thickness direction will not be described again in the following text.

[0062] The glue head 100 of the present application can respectively glue the first surface 211 and the second surface 212, and guide the glue 300 of the first surface 211 into the overflow groove 213, so as to ensure that the overflow groove 213 has sufficient glue 300, and then ensure that the first surface 211 and the second surface 212 have sufficient glue 300, and ensure that the glue amount of each part of the mounting groove 210 is roughly balanced, and ensure the sealing between the glue member 200 and the to-be-mounted member 400.

[0063] The following introduces the specific structure of the glue head 100 of an embodiment.

[0064] Referring to Figures 1 to 8 In an embodiment, the glue head 100 includes a connecting head 110 and a glue pipe 120. The glue pipe 120 is arranged at one end of the connecting head 110, and the glue pipe 120 has a glue channel 121 connected to the connecting head 110, and the glue pipe 120 also has a first glue hole 122 and a second glue hole 123 penetrating the glue channel 121, the first glue hole 122 is arranged on the side of the glue pipe 120 and faces the first surface 211, and the second glue hole 123 is arranged obliquely on the bottom of the glue pipe 120 and faces the second surface 212.

[0065] The glue pipe 120 further includes a flow guide part 124, which is protrudingly arranged on the side of the glue pipe 120 and faces the overflow groove 213, and is used to guide the glue 300 output by the first glue hole 122 into the overflow groove 213. Figure 8 For Figure 7 The glue head 100 shown in the figure is matched with the glue member 200 at A, and the local enlarged view is shown.

[0066] The connecting head 110 is a connecting part 130 of the glue head 100, the top of the connecting head 110 is used to connect the glue structure (not shown) of the glue device, and the bottom of the connecting head 110 is connected with the glue pipe 120. The connecting head 110 and the glue pipe 120 are hollowly arranged, and the hollow cavity of the glue head 100 is the glue channel 121. The glue structure delivers the glue 300 into the glue channel 121 through the connecting head 110, and then injects it into the mounting groove 210 through the glue head 100.

[0067] The side of the glue pipe 120 has the first glue hole 122, and the end of the glue pipe 120 away from the connecting head 110 is called the bottom of the glue pipe 120. That is, as shown in Figure 1 、 Figure 6 and Figure 7 The first glue hole 122 is located on the left side of the glue pipe 120. The first glue hole 122 penetrates the pipe wall of the glue pipe 120 along the thickness direction of the glue pipe 120, and is connected to the glue channel 121.

[0068] The bottom of the glue pipe 120 has an inclined second glue hole 123. That is, as shown in Figure 1 、 Figure 6 and Figure 7 , the first glue hole 122 is located on the left side of the glue pipe 120, the second glue hole 123 is towards the right side of the glue pipe 120, and the glue channel 121 penetrates the bottom wall of the glue pipe 120 in the height direction of the glue pipe 120 to form the second glue hole 123 at the bottom of the glue pipe 120.

[0069] The first glue hole 122 and the second glue hole 123 are both communicated to the glue channel 121, and the orientations of the first glue hole 122 and the second glue hole 123 are opposite. That is, the first glue hole 122 and the second glue hole 123 are towards both sides of the thickness direction of the glue pipe 120. In this way, after the bottom of the glue head 100 extends into the mounting groove 210, the first glue hole 122 is towards the first surface 211, and the second glue hole 123 is towards the second surface 212.

[0070] When the glue head 100 glues the mounting groove 210, the glue 300 enters the glue channel 121 of the glue pipe 120 through the connecting head 110, the glue 300 in the glue channel 121 enters the mounting groove 210 through the first glue hole 122 and the second glue hole 123, and adheres to the first surface 211, and the glue 300 in the glue channel 121 enters the mounting groove 210 through the second glue hole 123, and adheres to the second surface 212.

[0071] At the same time, the inclined second glue hole 123 can also inject part of the glue 300 into the third surface 214, and since the glue 300 has a certain flowability, the glue 300 on the first surface 211 and the second surface 212 can also flow to the third surface 214. In this way, when the glue head 100 glues in the mounting groove 210, the glue 300 can be coated on the first surface 211, the second surface 212 and the third surface 214.

[0072] Hereinafter, when describing the glue head 100 gluing the mounting groove 210, only the glue head 100 gluing the first surface 211 and the second surface 212 will be described as an example, and the glue to the third surface 214 will not be described.

[0073] In addition, in order to accurately inject the glue 300 output by the first glue hole 122 into the glue overflow groove 213, the glue pipe 120 of the present application is further provided with a flow guide portion 124 on the outer side wall thereof, the flow guide portion 124 protrudes from the outer side wall of the glue pipe 120 and is opposite to the glue overflow groove 213. The glue 300 output by the first glue hole 122 can flow along the flow guide portion 124, and then be injected into the glue overflow groove 213 through the flow guide portion 124.

[0074] That is, after the glue head 100 extends into the overflow groove 213, the bottom of the glue head 100 is located in the mounting groove 210, and the flow guide part 124 is opposite to the overflow groove 213 to guide the glue 300 output by the first glue hole 122 into the overflow groove 213, which has the effect of guiding flow and ensures that the glue 300 accurately enters the overflow groove 213. In this way, it can be ensured that the overflow groove 213 is filled with glue 300, and the glue 300 is prevented from overflowing outside the frame.

[0075] Referring to Figures 1 to 7 When the glue head 100 of the present application is used to glue the mounting groove 210 of the to-be-glued part 200, the glue 300 enters the glue channel 121 of the glue pipe 120 through the connecting head 110, and then the glue 300 in the glue pipe 120 is injected into the overflow groove 213 through the first glue hole 122, so that the glue 300 adheres to the first surface 211, and the glue 300 is injected into the second surface 212 through the second glue hole 123 and adheres to the second surface 212.

[0076] When the to-be-mounted part 400 is installed into the mounting groove 210, the surface of the to-be-mounted part 400 is pressed into the mounting groove 210 and is close to the second surface 212 of the to-be-glued part 200 until the bottom of the to-be-mounted part 400 touches the third surface 214 of the to-be-glued part 200, and the to-be-mounted part 400 stops moving. At this time, the first surface 211, the second surface 212 and the third surface 214 all have glue 300 in contact with the surface of the to-be-mounted part 400.

[0077] When the glue 300 solidifies, the glue 300 at the first surface 211, the glue 300 at the second surface 212 and the glue 300 at the third surface 214 can completely seal between the to-be-glued part 200 and the to-be-mounted part 400, and a sealed space is completely formed in the mounting groove 210 of the to-be-glued part 200, so that water vapor cannot enter, thereby ensuring the sealing between the to-be-glued part 200 and the to-be-mounted part 400.

[0078] In this way, the glue head 100 of the present application can simultaneously glue the first surface 211 and the second surface 212, and inject the glue 300 into the overflow groove 213 through the flow guide part 124, so that the first surface 211 and the second surface 212 both have the glue 300. After the edge of the to-be-mounted part 400 is installed into the mounting groove 210, the two surfaces of the to-be-mounted part 400 are respectively attached to the first surface 211 and the second surface 212 through the glue 300, thereby ensuring the sealing between the to-be-glued part 200 and the to-be-mounted part 400.

[0079] In this way, the second surface 212 does not need to be bonded to the to-be-mounted part 400 through overflow of the first surface 211, thereby avoiding the situation that the second surface 212 is not glued, and the glue head 100 can make the first surface 211 and the second surface 212 have sufficient glue 300, so as to realize effective sealing between the to-be-glued part 200 and the to-be-mounted part 400, and effectively prevent water vapor from penetrating from the surrounding.

[0080] The glue head 100 of the above embodiment is provided with the first glue hole 122 and the second glue hole 123 facing opposite directions on the glue pipe 120, and the flow guide part 124 is correspondingly arranged at the first glue hole 122. When the first glue hole 122 injects the glue 300 to the first surface 211, the flow guide part 124 can guide the glue 300 into the overflow groove 213, and at the same time, the second glue hole 123 injects the glue 300 to the second surface 212. In this way, it can be ensured that the overflow groove 213 has sufficient glue 300, and the first surface 211 and the second surface 212 have sufficient glue 300, the glue amount of each part of the mounting groove 210 is substantially balanced, and the sealing between the to-be-glued part 200 and the to-be-mounted part 400 is ensured.

[0081] Referring to Figures 1 to 3 , Figure 9 and Figure 10 , in an embodiment, the glue pipe 120 at least includes the first plate body 125 and the second plate body 126 facing opposite directions. The first plate body 125 faces the first surface 211, and the second plate body 126 faces the second surface 212. The first plate body 125 has the first glue hole 122, and the second plate body 126 has the second glue hole 123. Figure 9 For Figure 1 the front view of the glue head 100, Figure 10 for Figure 9 the sectional view of the glue head 100 at B-B.

[0082] The glue pipe 120 has the first plate body 125 and the second plate body 126 facing opposite directions in the thickness direction. The first plate body 125 has the first glue hole 122 penetrating in the thickness direction, and the first glue hole 122 faces the first surface 211. The size of the first plate body 125 in the height direction is smaller than the size of the second plate body 126 in the height direction. In this way, the bottom of the first plate body 125 and the bottom of the second plate body 126 can form the inclined second glue hole 123, and the second glue hole 123 faces the second surface 212.

[0083] In this way, the first glue-applying hole 122 and the second glue-applying hole 123 are arranged in opposite ways and are both connected to the inner cavity of the glue-applying tube 120. This allows the first glue-applying hole 122 to apply glue to the first surface 211 and the second glue-applying hole 123 to apply glue to the second surface 212. This ensures that the amount of glue 300 meets the sealing requirements between the part to be installed 400 and the part to be glued 200, while reducing the amount of glue 300 used and lowering costs.

[0084] In this embodiment, the glue applicator 120 is roughly square in shape, such as... Figures 1 to 10 As shown. Of course, in other embodiments of this application, the glue applicator 120 may also be circular, polygonal or other shapes, as long as the first glue applicator hole 122 is aligned with the first surface 211 and the second glue applicator hole 123 is aligned with the second surface 212.

[0085] See Figures 1 to 3 , Figure 9 and Figure 10 In one embodiment, the dispensing head 100 further includes a connecting portion 130, which connects the dispensing tube 120 and the connector 110. The connecting portion 130 is located between the connector 110 and the dispensing tube 120, and is used to achieve a transition connection between the connector 110 and the dispensing tube 120.

[0086] It is worth noting that the shape of the connecting part 130 is not limited in principle, as long as it can seamlessly connect the glue applicator tube 120 and the connector 110. Optionally, the connector 110, the connecting part 130, and the glue applicator tube 120 can be integrated into one piece. This ensures the sealing of the glue applicator head 100 at the connection point and prevents leakage from the joint during the glue application process.

[0087] See Figures 1 to 4 , Figures 9 to 12 In one embodiment, the shape of the first glue-applying hole 122 is circular, elliptical, oblong, rectangular, square, or rhomboid. Figure 11 for Figure 1 The image shown is a magnified view of the glue applicator 100 at point C. Figure 12 for Figure 9 The enlarged view of the glue applicator 100 at point D.

[0088] Understandably, the shape of the first glue-applying hole 122 is not limited in principle, as long as it allows the glue 300 to be injected into the glue overflow tank 213. In this embodiment, the shape of the first glue-applying hole 122 is oblong. Of course, in other embodiments of this application, the shape of the first glue-applying hole 122 may also be rectangular, circular, or other regular or irregular shapes.

[0089] See Figures 1 to 4 , Figures 9 to 12In an embodiment, the flow guide 124 is arranged around the first glue hole 122. That is, the longitudinal section of the flow guide 124 is in a closed shape, the flow guide 124 protrudes from the outer wall of the glue pipe 120, and is arranged around the first glue hole 122.

[0090] In this way, the annular channel surrounded by the flow guide 124 can guide the glue 300 output by the first glue hole 122 to guide the glue 300 output by the first glue hole 122 into the glue overflow groove 213, and can also prevent the glue 300 output by the first glue hole 122 from overflowing the mounting groove 210, thereby ensuring the accuracy of glue injection.

[0091] Referring to Figures 1 to 4 , Figures 9 to 12 In an embodiment, the longitudinal section of the flow guide 124 is adapted to the longitudinal section of the first glue hole 122. That is, the longitudinal section of the flow guide 124 is the same as the longitudinal section of the first glue hole 122.

[0092] In this embodiment, the first glue hole 122 is in an oblong shape, and the longitudinal section of the flow guide 124 is also in an oblong shape. In this way, the glue 300 output by the oblong first glue hole 122 can accurately enter the oblong flow guide 124 and be transported to the glue overflow groove 213 through the oblong flow guide 124.

[0093] In other embodiments of the present application, the first glue hole 122 is in a square, circular or other shape, and the longitudinal section of the flow guide 124 is adapted to the shape of the first glue hole 122 to ensure that the glue 300 output by the first glue hole 122 accurately enters the glue overflow groove 213.

[0094] Of course, in other embodiments of the present application, the longitudinal section of the flow guide 124 is different from the longitudinal section of the first glue hole 122, and the longitudinal section area of the flow guide 124 is greater than the longitudinal section area of the first glue hole 122.

[0095] That is, the longitudinal section of the flow guide 124 can also be different from the longitudinal section of the first glue hole 122, as long as the longitudinal section area of the flow guide 124 is greater than the longitudinal section area of the first glue hole 122. In this way, the glue 300 output by the first glue hole 122 can be accurately output through the flow guide 124, and the glue 300 output by the first glue hole 122 can be prevented from being blocked by the flow guide 124.

[0096] Exemplarily, the longitudinal section shape of the flow guide part 124 is rectangular, the longitudinal section shape of the first glue injection hole 122 is oblong, and the longitudinal section area of the first glue injection hole 122 is smaller than the longitudinal section area of the flow guide part 124. Of course, the shapes of the flow guide part 124 and the first glue injection hole 122 can also be other shapes.

[0097] Referring to Figures 6 to 8 In an embodiment, the height dimension of the flow guide part 124 is smaller than the height dimension of the glue overflow groove 213 along the height direction of the glue injection tube 120. That is, the dimension of the flow guide part 124 along the height direction is smaller than the dimension of the glue overflow groove 213 along the height direction.

[0098] In this way, after the glue injection head 100 is inserted into the mounting groove 210, the flow guide part 124 can be inserted into the glue overflow groove 213, so that the flow guide part 124 can accurately inject the glue 300 into the glue overflow groove 213, avoiding the glue 300 overflowing from the edge of the glue overflow groove 213, and further avoiding the glue 300 overflowing from the mounting groove 210.

[0099] In another embodiment of the present application, the flow guide part 124 includes a guide part and two limiting parts, the two limiting parts are arranged on the side surface of the flow guide part 124, and the guide part communicates the first glue injection hole 122 and the glue overflow groove 213. That is, the flow guide part 124 is arranged below the first glue injection hole 122 in a semi-enclosed structure.

[0100] That is, the flow guide part 124 can be in the form of a flow guide plate, the guide part is the main flow guide plate of the flow guide part 124, and the limiting parts are arranged on the front and back sides of the flow guide part 124 to guide and limit the glue 300 transported by the guide part.

[0101] After the glue 300 is transported to the guide part by the first glue injection hole 122, the glue 300 can flow along the guide part, and at the same time, the limiting parts can limit the glue 300 in the guide part, avoiding the glue 300 overflowing from the front and back sides of the guide part. In this way, the guide part can accurately transport the glue 300 into the glue overflow groove 213.

[0102] In an embodiment, the guide part is coplanar with the bottom wall of the first glue injection hole 122, or the guide part is below the bottom wall of the first glue injection hole 122. That is, the guide part is flush with the bottom wall of the first glue injection hole 122, or lower than the bottom wall of the first glue injection hole 122, to guide the glue 300 output by the first glue injection hole 122.

[0103] Referring to Figures 1 to 10In an embodiment, the size of the guide portion 124 along the thickness direction of the glue pipe 120 ranges from 0.5mm to 5mm. That is, the size of the guide portion 124 extending out of the side of the glue pipe 120 ranges from 0.5mm to 5mm, which is determined according to the size of the guide portion 124 along the thickness direction. In this way, the guide portion 124 can accurately extend into the glue overflow groove 213.

[0104] In an embodiment, the ratio of the glue output of the first glue hole 122 to the glue output of the second glue hole 123 ranges from 1 / 2 to 1 / 4. That is, the ratio of the glue output of the first glue hole 122 to the glue output of the second glue hole 123 ranges from 1 / 2 to 1 / 4.

[0105] In this way, the glue overflow groove 213 can be more stably filled, and the glue 300 at the first surface 211 can be prevented from overflowing to the outside of the mounting groove 210, while the glue outputs of the first glue hole 122 and the second glue hole 123 can be accurately controlled, the sealing effect of the to-be-mounted member 400 and the to-be-glued member 200 at the connection can be ensured, and the amount of glue can be reduced.

[0106] In an embodiment, the glue pipe 120 is made of an anti-adhesion material. In this way, the glue pipe 120 can be prevented from adhering to the glue 300 as much as possible, and the glue pipe 120 can be prevented from taking out the glue 300 in the mounting groove 210 by the glue head 100, so that the mounting groove 210 has enough glue 300, and the service life of the glue pipe 120 can be ensured.

[0107] In an embodiment, the glue pipe 120 is made of Teflon material, or the inner wall and the outer wall of the glue pipe 120 are sprayed with Teflon material. After the outer side of the glue pipe 120 is sprayed with Teflon material or the glue pipe 120 is made of Teflon material, the anti-adhesion effect of the glue pipe 120 can be ensured, and the service life of the glue head 100 can be prolonged.

[0108] Of course, in other embodiments of the present application, the glue pipe 120 can also be made of other anti-adhesion materials, as long as the glue pipe 120 can be prevented from adhering to the glue 300 and the service life of the glue pipe 120 can be prolonged.

[0109] Referring to Figures 1 to 13 , Figure 13 To Figure 7The partial view shows the installation of the to-be-installed part 400 in the installation groove 210 of the to-be-glued part 200. When the glue head 100 of the present application is used to glue the installation groove 210 of the to-be-glued part 200, the glue 300 enters the glue channel 121 of the glue pipe 120 through the connecting head 110, and then the glue 300 in the glue pipe 120 is injected into the overflow groove 213 through the first glue hole 122, so that the glue 300 adheres to the first surface 211, and the glue 300 is injected into the second surface 212 through the second glue hole 123 and adheres to the second surface 212.

[0110] When the to-be-installed part 400 is installed into the installation groove 210, the surface of the to-be-installed part 400 is pressed into the installation groove 210 and is attached to the second surface 212 of the to-be-glued part 200 until the bottom of the to-be-installed part 400 touches the third surface 214 of the to-be-glued part 200, and the to-be-installed part 400 stops moving. At this time, the first surface 211, the second surface 212 and the third surface 214 are all in contact with the surface of the to-be-installed part 400.

[0111] When the glue 300 solidifies, the glue 300 at the first surface 211, the glue 300 at the second surface 212 and the glue 300 at the third surface 214 can completely seal the to-be-glued part 200 and the to-be-installed part 400, and a sealed space is formed in the installation groove 210 of the to-be-glued part 200, so that water vapor cannot enter, thereby ensuring the sealing between the to-be-glued part 200 and the to-be-installed part 400.

[0112] In this way, the glue head 100 of the present application can glue the first surface 211 and the second surface 212 at the same time, and the glue 300 is injected into the overflow groove 213 through the flow guide part 124, so that the first surface 211 and the second surface 212 both have the glue 300. After the edge of the to-be-installed part 400 is installed into the installation groove 210, the two surfaces of the to-be-installed part 400 are attached to the first surface 211 and the second surface 212 through the glue 300 respectively, thereby ensuring the sealing between the to-be-glued part 200 and the to-be-installed part 400.

[0113] In this way, the second surface 212 does not need to be connected to the to-be-installed part 400 by overflow gluing, thereby avoiding the situation that the first surface 211 has no glue, and the glue head 100 can make the first surface 211 and the second surface 212 have enough glue 300, thereby realizing effective sealing between the to-be-glued part 200 and the to-be-installed part 400 and effectively preventing water vapor from entering from the surrounding.

[0114] In the glue injection process, the side of the glue injection pipe 120 is provided with the flow guide part 124 surrounding the first glue injection hole 122, which can better guide the glue 300 to the overflow groove 213, so that the glue 300 fills the overflow groove 213. Compared with the conventional structure without holes or without bosses after the holes are opened, the glue injection head 100 of the present application can make the glue 300 more fully fill the overflow groove 213 through the flow guide part 124.

[0115] As shown in Figure 13 , after the glue injection, the glue 300 on the first surface 211 is farther away from the side of the to-be-installed part 400, and the uniformity is better, which ensures that the first surface 211 and the second surface 212 have enough glue 300, ensures that the glue amount of each part of the installation groove 210 is roughly balanced, and ensures the sealing between the to-be-glued part 200 and the to-be-installed part 400.

[0116] At the same time, as shown in Figure 13 , after the overflow groove 213 is filled with glue 300, the glue 300 is closer to the upper part of the installation groove 210, and there is a certain distance from the third surface 214, which has a better water-blocking effect, further ensuring the sealing between the to-be-glued part 200 and the to-be-installed part 400.

[0117] The glue injection head 100 of the present application is provided with the flow guide part 124 on the side of the glue injection pipe 120, which can accurately align the first glue injection hole 122 with the overflow groove 213, thereby ensuring that the glue injection head 100 injects glue more accurately at the overflow groove 213 of the first surface 211, avoiding excess glue 300 outside the overflow groove 213, and also avoiding the existence of voids in the overflow groove 213, ensuring better adhesion between the to-be-installed part 400 and the to-be-glued part 200, and further making the to-be-glued part 200 have greater advantages in terms of load, etc., improving the structural strength of the to-be-glued part 200.

[0118] The glue injection head 100 of the present application is provided with the first glue injection hole 122 and the second glue injection hole 123 on the glue injection pipe 120, and the flow guide part 124 is correspondingly arranged at the first glue injection hole 122. When the first glue injection hole 122 injects glue 300 into the first surface 211, the flow guide part 124 can guide the glue 300 into the overflow groove 213, and at the same time, the second glue injection hole 123 injects glue 300 into the second surface 212, which can ensure that the overflow groove 213 has enough glue 300, and further ensure that the first surface 211 and the second surface 212 have enough glue 300, ensure that the glue amount of each part of the installation groove 210 is roughly balanced, and ensure the sealing between the to-be-glued part 200 and the to-be-installed part 400.

[0119] When the glue head 100 is used to glue the frame of the photovoltaic module, the glue head 100 injects the glue 300 into the overflow groove 213 through the first glue injection hole 122 and injects the glue 300 into the second surface 212 through the second glue injection hole 123, so as to ensure that the overflow groove 213 and the second surface 212 have enough glue 300, and further ensure that the glue 300 on the first surface 211 is more uniform.

[0120] When the tempered glass is installed, the glue 300 on the first surface 211 and the second surface 212 is simultaneously extruded by the tempered glass, which further fills the installation groove 210 of the frame, so that the glue 300 fills the gap of the installation groove 210 and covers the water-blocking tape. After the glue 300 solidifies, the glue 300 and the water-blocking tape tightly adhere the frame to the tempered glass, thereby playing a double protection role and greatly reducing the probability of rainwater introduction.

[0121] Meanwhile, the amount of glue can be controlled by the opening size of the first glue injection hole 122 and the second glue injection hole 123 and the pressure of the glue injection structure such as the glue pump, so that the glue 300 will not overflow to the surface of the to-be-installed part 400, the cleaning difficulty is reduced, and the to-be-installed part 400 is less likely to be scratched due to cleaning. Moreover, the frame assembling machine does not need to be specially adjusted, and the frame can be assembled in a normal state, thereby reducing the equipment adjustment time.

[0122] The glue head 100 can be used as it is, that is, the main structure of the glue head 100 is not changed, the side structure of the glue injection pipe 120 is changed, the second glue injection hole 123 is retained at the bottom of the glue injection pipe 120, and the first glue injection hole 122 is arranged on the side of the glue injection pipe 120. In this way, the glue head 100 can be seamlessly compatible with the current glue injection device.

[0123] Moreover, after the amount of glue injected from the first glue injection hole 122 and the second glue injection hole 123 is limited, the glue head 100 can more accurately control the amount of glue during glue injection, reduce the risk of contamination of the glue 300 on the first surface 211 of the to-be-glued part 200, facilitate cleaning of the excess glue 300 after the to-be-glued part 200 and the to-be-installed part 400 are assembled, improve the operation efficiency, and reduce the production cost.

[0124] The glue head 100 is connected to the glue injection structure through the connecting head 110, and the glue injection structure injects the glue 300 into the to-be-glued part 200 through the glue head 100. Optionally, the glue injection structure is a glue pump. Of course, in other embodiments of the present application, the glue injection structure can also be other structures for delivering the glue 300 to the glue injection pipe 120.

[0125] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0126] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
