Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glue injection processing, in particular to a glue injection head and a glue injection 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] The conventional glue injection method is to inject glue at an angle of 45 degrees by using a beveled nozzle, and the glue adheres to the BC surface in the groove of the frame. A small amount of glue is extruded to the A surface by the glass, and most of the glue is extruded to the outside through the C surface to form a round glue strip. At this time, the A and C surfaces are sealed by the glue, and the inside of the groove of the frame has formed a sealed environment, and the B surface has little effect on the large amount of glue, resulting in material waste and increased cost of the module.

[0004] At present, the area of the photovoltaic module is getting larger and larger, and excessive glue injection will increase the cost, thereby increasing the material cost of the photovoltaic module. In order to reduce the cost of the photovoltaic module, most of the purposes are achieved by reducing the amount of glue to reduce the cost and increase the efficiency.

[0005] However, reducing the amount of glue may cause a lack of glue on the C surface, thereby causing insufficient sealing between the glass and the C surface, resulting in air and water leakage at the edge of the photovoltaic module. At the same time, the load performance of the photovoltaic module is reduced, the risk of explosion is increased, and the power generation efficiency and service life of the photovoltaic module are affected.

[0018] In an embodiment of the present application, the width dimension of the second glue hole is greater than the width dimension of the first glue hole along the width direction of the glue pipe.

[0019] In an embodiment of the present application, the height dimension of the second glue hole is greater than the height dimension of the first glue hole along the height direction of the glue pipe.

[0020] In an embodiment of the present application, the first glue hole is circular, oblong, elliptical, rectangular, square or diamond-shaped.

[0021] In an embodiment of the present application, the second glue hole is circular, elliptical, oblong, rectangular, square or diamond-shaped.

[0022] In an embodiment of the present application, the distance between the bottom wall of the first glue hole and the bottom of the glue pipe is 1 / 5 to 3 / 4 of the depth of the installation groove.

[0023] In an embodiment of the present application, the end of the glue pipe away from the connector is a sealing portion.

[0024] The sealing part seals the glue injection channel at the bottom of the glue injection pipe, or the glue injection pipe further has a third glue injection hole penetrating the sealing part along the height direction and communicating with the glue injection channel, and the area of the third glue injection hole is 1 / 10-1 / 5 of the area of the first glue injection hole.

DETAILED DESCRIPTION

[0043] In order to make the above objectives, features and advantages of the present application more apparent and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in many different ways from those described herein without departing from the scope of the present application, and skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0044] ​​​​​​​​In the description of the application, it should be understood that, if there are these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, 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 application and simplifying the description, and do not indicate or imply 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 a limitation on the application.

[0045] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if there are terms "a plurality of", the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0046] In this application, unless otherwise explicitly specified and limited, if there are terms "installation", "connection", "connection", "fixation" and the like, these terms should be broadly understood. 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 this application can be understood according to the specific circumstances.

[0047] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on" or "below" the second feature, the meaning can be 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 that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0048] It is to be noted that if an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intervening element. If an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions used herein are used only for the purpose of illustration and do not indicate the only embodiment.

[0049] It can be understood that at present, in the process of assembling the heterojunction battery assembly, sealing glue needs to be injected into the mounting groove of the frame. The traditional glue injection method is to inject glue at an angle of 45° by using a beveled glue head. The glue adheres to the BC surface in the frame groove. A small amount of glue is overflowed to the A surface platform by glass extrusion. Most of the glue is overflowed to the outside through the C surface to form a rounded glue strip. At this time, the A and C surfaces are sealed by the glue, and a sealed environment has been formed inside the frame groove. The B surface has little effect on the large amount of glue, resulting in material waste and increased cost of the assembly.

[0050] At present, the area of photovoltaic modules is getting larger and larger. Excessive glue injection will lead to increased cost, and in turn, increase the material cost of photovoltaic modules. In order to reduce the cost of photovoltaic modules, most of them are through reducing the amount of glue to achieve the purpose of reducing cost and increasing efficiency. However, reducing the amount of glue may cause C surface glue deficiency, and in turn, the sealing of glass and C surface is insufficient, resulting in edge air leakage and water leakage of photovoltaic modules. At the same time, the load performance of photovoltaic modules is reduced, the risk of explosion is increased, and the power generation efficiency and service life of photovoltaic modules are affected.

[0051] Therefore, referring to Figures 1 to 3 The application provides a new type of glue injection head 100. Figure 1 The schematic view of the glue injection head 100 of an embodiment of the application from one perspective, Figure 2 The schematic view of the glue injection head 100 from another perspective, Figure 1 The perspective view of the glue injection head 100. Figure 3 Figure 1 The perspective view of the glue injection head 100.

[0052] The glue injection head 100 is applied to a glue injection device (not shown) and is used for injecting glue 300 into a mounting groove 210 of a to-be-glued part 200. The edge of a to-be-mounted part (not shown) is arranged in the mounting groove 210, and the two side surfaces of the to-be-mounted part can contact the mounting groove 210 of the to-be-mounted part through the glue 300, so as to realize the sealed connection between the to-be-glued part 200 and the to-be-mounted part and ensure the high sealing performance of the connection between the to-be-glued part 200 and the to-be-mounted part.

[0053] ​In the present application, injecting the adhesive 300 into the mounting groove 210 of the member to be glued 200 is called gluing. In the following description, the injection of the adhesive 300 into the mounting groove 210 by the gluing head 100 is sometimes described as gluing.

[0054] Optionally, the adhesive 300 is silicone adhesive, which has good viscosity and can well realize the sealing between the member to be glued 200 and the member to be mounted. Of course, in other embodiments of the present application, the adhesive 300 can also be other adhesives that can play a role in bonding and sealing.

[0055] In the present embodiment, the member to be glued 200 is the frame of a photovoltaic module, and the member to be mounted is the tempered glass of the photovoltaic module. Generally, the edge of the tempered glass of the photovoltaic module is mounted in the frame.

[0056] After the adhesive 300 is injected into the frame, the frame and the tempered glass are sealed and connected by the adhesive 300, thereby ensuring the effective sealing of the photovoltaic module, preventing water vapor from entering the inside of the photovoltaic module, thereby ensuring the use performance of the photovoltaic module and avoiding the explosion of the photovoltaic module.

[0057] Of course, in other embodiments of the present application, the member to be glued 200 can also be other structures or components that need to be glued and sealed, and the member to be mounted can also be other components that need to be mounted to the member to be glued 200.

[0058] The present application only takes the member to be glued 200 as the frame of the photovoltaic module and the member to be mounted as the tempered glass of the photovoltaic module as an example for description, and in the following description of the structure of the gluing head 100, the member to be glued 200 is replaced by the frame of the photovoltaic module and the member to be mounted is replaced by the tempered glass of the photovoltaic module.

[0059] To better illustrate the structure of the gluing head 100, the structure of the member to be glued 200 is first introduced here. Referring to Figures 4 to 7 , Figure 4 To Figure 1 the schematic view of the cooperation between the gluing head 100 and the member to be glued 200 from one perspective, Figure 5 to Figure 4 the schematic view of the cooperation between the gluing head 100 and the member to be glued 200 from another perspective, Figure 6 to Figure 5 the side view of the cooperation between the gluing head 100 and the member to be glued 200, Figure 7 to Figure 6 the perspective view of the cooperation between the gluing head 100 and the member to be glued 200. The member to be glued 200 is arranged in a substantially strip shape.

[0060] The member to be glued 200 has a recessed mounting groove 210, and the mounting groove 210 has a first surface 211 and a second surface 212 arranged facing each other, as shown in Figures 4 to 7The glue head 100 is used to glue the installation groove 210, and the glue is injected to the first surface 211 and the second surface 212 respectively. After the to-be-installed member is installed in the installation groove 210, the two side surfaces of the to-be-installed member are sealedly 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.

[0061] The up-down-left-right front-back directions of the present application are shown in Figure 1 and Figure 4 The up-down direction of the glue head 100 is the height direction, the top-bottom direction and the extension direction, the left-right direction of the glue head 100 is the width direction, and the front-back direction of the glue head 100 is the thickness direction. The installation groove 210 is recessed along the height direction, the first surface 211 and the second surface 212 are oppositely arranged along the thickness direction, and the to-be-glued member 200 extends along the width direction. The height direction, the width direction and the thickness direction will not be described below.

[0062] When the glue head 100 of the present application is used to glue the installation groove 210 of the to-be-glued member 200, the glue 300 can be injected to the first surface 211 and the second surface 212 respectively. After the to-be-installed member is installed in the installation groove 210 of the to-be-glued member 200, the to-be-installed member can be sealedly contacted with the first surface 211 and the second surface 212 without glue overflow through the gap, so as to avoid the situation that the second surface 212 is short of glue due to the reduction of the amount of glue, to reduce the amount of glue 300, to reduce the cost, and to ensure the product quality and the service life.

[0063] The specific structure of the glue head 100 of an embodiment is introduced below.

[0064] Referring to Figures 1 to 7 In an embodiment, the glue head 100 comprises 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 communicated to the connecting head 110. The end of the glue pipe 120 away from the connecting head 110 is closed, and the glue pipe 120 has a first glue hole 122 and a second glue hole 123. The first glue hole 122 and the second glue hole 123 are arranged at two opposite pipe walls of the glue pipe 120 and penetrate the glue channel 121. The first glue hole 122 can face the first surface 211, and the second glue hole 123 can face the second surface 212.

[0065] The connector 110 is a connecting part 130 of the dispensing head 100. The top of the connector 110 is used to connect to the dispensing structure (not shown) of the dispensing device, and the bottom of the connector 110 is connected to the dispensing tube 120. The connector 110 and the dispensing tube 120 are hollow, and the hollow cavity of the dispensing head 100 is the dispensing channel 121. The dispensing structure delivers the adhesive 300 through the connector 110 to the dispensing channel 121, and then injects it into the mounting groove 210 through the dispensing head 100.

[0066] The end of the glue applicator 120 furthest from the connector 110 is the bottom of the glue applicator 120, and the bottom of the glue applicator 120 is closed. That is, the glue application channel 121 does not extend to the bottom of the glue applicator 120; the bottom of the glue application channel 121 is closed, making it a blind hole. Thus, after the glue 300 enters the glue application channel 121 from the connector 110, the glue application channel 121 will not inject the glue 300 into the mounting groove 210 from the bottom.

[0067] The glue applicator 120 has a first glue applicator hole 122 and a second glue applicator hole 123 respectively on its two opposite walls along the thickness direction. For example... Figure 1 , Figure 4 and Figure 5 As shown, a first glue-applying hole 122 is provided on the left side wall of the glue-applying tube 120, and a second glue-applying hole 123 is provided on the right side wall of the glue-applying tube 120. Furthermore, the first glue-applying hole 122 penetrates the tube wall along the thickness direction and connects to the glue-applying channel 121, and the second glue-applying hole 123 penetrates the tube wall along the thickness direction and connects to the glue-applying channel 121.

[0068] The first glue-applying hole 122 and the second glue-applying hole 123 are disposed on two opposite walls of the glue-applying tube 120 along the thickness direction, that is, the first glue-applying hole 122 and the second glue-applying hole 123 face opposite directions, respectively facing the two sides of the glue-applying tube 120 along the thickness direction. In this way, after the bottom of the glue-applying tube 120 extends into the mounting groove 210, the first glue-applying hole 122 faces the first surface 211, and the second glue-applying hole 123 faces the second surface 212.

[0069] When the caulking head 100 applies caulking compound to the mounting groove 210, the caulking compound 300 enters the caulking channel 121 of the caulking tube 120 through the connector 110. The caulking compound 300 in the caulking channel 121 enters the mounting groove 210 through the first caulking hole 122 and the second caulking hole 123 and adheres to the first surface 211. The caulking compound 300 in the caulking channel 121 enters the mounting groove 210 through the second caulking hole 123 and adheres to the second surface 212.

[0070] In this way, the glue head 100 can simultaneously glue the first surface 211 and the second surface 212, and the first surface 211 and the second surface 212 are both provided with the glue 300. After the edge of the to-be-installed part is installed into the installation groove 210, the two surfaces of the to-be-installed part are respectively attached to the first surface 211 and the second surface 212 through the glue 300, so as to ensure the sealing between the to-be-glued part 200 and the to-be-installed part.

[0071] In this way, the first surface 211 is not required to be connected to the to-be-installed part through the glue overflow of the second surface 212, so as to avoid the situation that the second surface 212 is not provided with glue, and the glue head 100 can ensure that the first surface 211 and the second surface 212 are both provided with sufficient glue 300, so as to effectively seal the to-be-glued part 200 and the to-be-installed part, and effectively prevent the water vapor from penetrating from the surrounding.

[0072] In addition, when the to-be-installed part, such as the photovoltaic module, has a large area, the glue is respectively applied to the first surface 211 and the second surface 212 through the glue pipe 120, and the first surface 211 and the second surface 212 are not required to be provided with the glue 300 through the glue overflow, so as to reduce the amount of the glue 300 while ensuring the sealing between the to-be-installed part and the to-be-glued part 200, reduce the cost, and ensure the power generation efficiency and the service life of the photovoltaic module.

[0073] The glue head 100 of the above embodiment is provided with the first glue hole 122 and the second glue hole 123 which are oppositely arranged on the two opposite walls of the glue pipe 120 and are oppositely arranged, so that the glue head 100 can simultaneously glue the first surface 211 and the second surface 212, and the to-be-installed part can be in sealing contact with the first surface 211 and the second surface 212 without glue overflow through the gap, so as to avoid the situation that the second surface 212 is not provided with glue due to the reduction of the amount of glue, reduce the amount of the glue 300 while ensuring the sealing between the to-be-glued part 200 and the to-be-installed part, reduce the cost, and ensure the product quality and the service life.

[0074] Referring to Figures 1 to 3 , Figure 8 and Figure 9 In an embodiment, the glue pipe 120 at least includes the first plate body 124 and the second plate body 125 which are oppositely arranged, the first plate body 124 is arranged towards the first surface 211, the second plate body 125 is arranged towards the second surface 212, the first plate body 124 is provided with the first glue hole 122, and the second plate body 125 is provided with the second glue hole 123. Figure 8 As shown in the front view of the glue head 100, Figure 1 As shown in the sectional view of the glue head 100 at A-A, Figure 9 As shown in the sectional view of the glue head 100 at A-A, Figure 8

[0075] ​The glue applicator 120 has a first plate 124 and a second plate 125 opposite each other in the thickness direction, and the bottoms of the first plate 124 and the second plate 125 are directly connected so that the glue application channel 121 is sealed at the bottom of the glue applicator 120. At the same time, the first plate 124 has a first glue application hole 122 extending in the thickness direction, and the second plate 125 has a second glue application hole 123 extending in the thickness direction.

[0076] 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 and the part to be glued 200, while reducing the amount of glue 300 used and lowering costs.

[0077] In this embodiment, the glue applicator 120 is roughly square in shape, such as... Figures 1 to 9 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.

[0078] See Figures 1 to 3 , Figure 8 and Figure 9 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.

[0079] 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.

[0080] See Figure 4 , Figure 6 , Figure 7 and Figure 10 In one embodiment, the mounting groove 210 further includes an overflow groove 213, which is recessed into the first surface 211. Along the height direction of the glue applicator 120, the first glue applicator hole 122 is at least partially located within the overflow groove 213. Figure 10 for Figure 7 The enlarged view of the glue applicator 100 mating with the part to be glued 200 at point B.

[0081] The glue 300 is injected into the overflow groove 213, and gradually fills the overflow groove 213, and then the glue 300 can overflow from the overflow groove 213. In this way, the overflow groove 213 can accommodate more glue 300, and can prevent too much glue 300 from moving out. When the surface of the to-be-mounted member is in contact with the first surface 211, the glue 300 overflowing from the overflow groove 213 can be in contact with the surface of the to-be-mounted member, ensuring the sealing between the to-be-mounted member and the to-be-glued member 200.

[0082] When the first glue injection hole 122 injects the glue 300 into the mounting groove 210, part of the glue 300 enters the mounting groove 210 and adheres to the first surface 211, and part of the glue 300 enters the overflow groove 213. In this way, the to-be-glued member 200 can be sealed and bonded to the to-be-mounted member through the first surface 211 and the glue 300 in the overflow groove 213, further improving the sealing between the to-be-mounted member and the to-be-glued member 200.

[0083] Referring to Figure 4 , Figure 6 , Figure 7 and Figure 10 , in an embodiment, the bottom wall of the first glue injection hole 122 is higher than the overflow groove 213. That is, the first glue injection hole 122 is arranged higher than the overflow groove 213. It can be understood that the glue 300 has certain viscosity and fluidity, and after the first glue injection hole 122 is arranged higher than the overflow groove 213, the first glue injection hole 122 can inject the glue 300 into the overflow groove 213, so that the glue 300 adheres to the first surface 211.

[0084] Of course, in other embodiments of the present application, the bottom wall of the first glue injection hole 122 can also be flush with the overflow groove 213. That is, the first glue injection hole 122 and the overflow groove 213 are substantially at the same level. In this way, the first glue injection hole 122 can also inject the glue 300 into the overflow groove 213.

[0085] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, along the height direction of the glue injection pipe 120, the second glue injection hole 123 is located above the first glue injection hole 122. Figure 11 For Figure 3 the enlarged view of the glue injection head 100 at C, Figure 12 for Figure 3 the rear view of the glue injection head 100.

[0086] In Figure 3 , Figure 9 , Figure 11 and Figure 12In the embodiment, the first glue injection hole 122 is located at the lower side, and the second glue injection hole 123 is located at the upper side. The first glue injection hole 122 is arranged corresponding to the glue overflow groove 213, and the second glue injection hole 123 is arranged corresponding to the upper side of the second surface 212. In this way, the first glue injection hole 122 injects the glue 300 into the glue overflow groove 213, and the second glue injection hole 123 injects the glue 300 above the second surface 212.

[0087] Since the glue 300 has certain viscosity and fluidity, the glue 300 injected by the second glue injection hole 123 can flow along the second surface 212 and adhere to the second surface 212. When the to-be-installed part is installed into the installation groove 210, the to-be-installed part is squeezed from the first surface 211 of the to-be-glued part 200 and contacts the second surface 212 until the bottom of the to-be-installed part contacts the third surface 214, and the to-be-installed part stops moving.

[0088] When the glue 300 solidifies, the contact position of the first surface 211 with the to-be-installed part and the contact position of the second surface 212 with the to-be-installed part are completely sealed by the glue 300, the inside of the installation groove 210 forms a sealed space, and water vapor cannot enter, thereby ensuring the sealing effect of the to-be-installed part and the to-be-glued part 200 at the connection position, and reducing the amount of glue 300 used to achieve the purpose of reducing cost and increasing efficiency.

[0089] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, along the height direction of the glue injection pipe 120, there is a preset interval d1 between the bottom wall of the second glue injection hole 123 and the top wall of the first glue injection hole 122. That is, there is a preset interval between the bottom of the second glue injection hole 123 and the top of the first glue injection hole 122 along the height direction.

[0090] That is, the first glue injection hole 122 and the second glue injection hole 123 do not overlap in the height direction. In this way, the glue injection amount of the first glue injection hole 122 and the second glue injection hole 123 can be accurately ensured, and the glue 300 can be accurately injected into the glue overflow groove 213 and accurately adhered to the second surface 212, thereby ensuring the sealing effect of the to-be-installed part and the to-be-glued part 200 at the connection position.

[0091] In an embodiment, the size of the preset interval ranges from 2 mm to 8 mm. That is, the distance between the bottom wall of the second glue injection hole 123 and the top wall of the first glue injection hole 122 ranges from 2 mm to 8 mm. In this way, the glue 300 can be accurately injected into the glue overflow groove 213 and accurately adhered to the second surface 212, thereby ensuring the sealing effect of the to-be-installed part and the to-be-glued part 200 at the connection position.

[0092] Referring to Figures 5 to 7In an embodiment, the second glue hole 123 is partially located in the mounting groove 210 and partially located above the top surface of the glue-recipient 200. That is, the second glue hole 123 is partially located in the mounting groove 210 and partially located outside the mounting groove 210.

[0093] After the glue 300 flows out of the second glue hole 123, the glue 300 can be attached to the second surface 212, and part of the glue 300 is located at the edge of the top of the second surface 212. Because the glue 300 has certain viscosity and fluidity, the glue 300 at the top of the second surface 212 can flow down along the second surface 212, while part of the glue 300 stays at the top of the second surface 212, ensuring the sealing effect of the connection between the to-be-mounted component and the glue-recipient 200.

[0094] In an embodiment, the height of the top wall of the second glue hole 123 above the top surface of the glue-recipient 200 is 2mm-5mm. That is, the height of the second glue hole 123 above the mounting groove 210 is 2mm-5mm, which can ensure the sealing effect of the connection between the to-be-mounted component and the glue-recipient 200.

[0095] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, the first glue hole 122 is circular, elliptical, oblong, rectangular, square or diamond-shaped. It can be understood that the shape of the first glue hole 122 is not limited in principle as long as it can inject glue 300 into the glue overflow groove 213.

[0096] In the embodiment, the first glue hole 122 is oblong. Of course, in other embodiments of the application, the first glue hole 122 can also be rectangular, circular or other regular or irregular shapes.

[0097] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, the second glue hole 123 is circular, elliptical, oblong, rectangular, square or diamond-shaped. It can be understood that the shape of the second glue hole 123 is not limited in principle as long as it can inject glue 300 into the second surface 212.

[0098] In the embodiment, the second glue hole 123 is oblong. Of course, in other embodiments of the application, the second glue hole 123 can also be rectangular, circular or other regular or irregular shapes.

[0099] Referring to Figure 3 and Figure 11In the embodiment, the first glue injection hole 122 has the same shape as the second glue injection hole 123. That is, the first glue injection hole 122 and the second glue injection hole 123 are both long circular holes. The first glue injection hole 122 and the second glue injection hole 123 in the shape of long circular holes inject the glue 300 into the mounting groove 210.

[0100] Of course, in other embodiments of the present application, the first glue injection hole 122 and the second glue injection hole 123 can also have different shapes. For example, the first glue injection hole 122 is long circular, the second glue injection hole 123 is rectangular or circular, and of course, the first glue injection hole 122 and the second glue injection hole 123 can also have other shapes as long as they can inject the glue 300 into the mounting groove 210.

[0101] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, the area of the second glue injection hole 123 is greater than the area of the first glue injection hole 122. In this way, the glue injection amount of the first glue injection hole 122 is less than the glue injection amount of the second glue injection hole 123, realizing accurate control of the glue injection amount, reducing the glue amount while ensuring the sealing effect of the to-be-mounted part and the to-be-glued part 200 at the connection.

[0102] Referring to Figures 1 to 3 , Figure 9 , Figure 11 and Figure 12 , in an embodiment, along the width direction of the glue injection pipe 120, the width dimension of the second glue injection hole 123 is greater than the width dimension of the first glue injection hole 122, and / or, along the height direction of the glue injection pipe 120, the height dimension of the second glue injection hole 123 is greater than the height dimension of the first glue injection hole 122.

[0103] In the embodiment, the height dimension of the first glue injection hole 122 is less than the height dimension of the second glue injection hole 123, and the width dimension of the first glue injection hole 122 is less than the width dimension of the second glue injection hole 123. In this way, accurate control of the glue injection amount is realized, reducing the glue amount while ensuring the sealing effect of the to-be-mounted part and the to-be-glued part 200 at the connection.

[0104] Of course, in other embodiments of the present application, only the height dimension of the first glue injection hole 122 can be less than the height dimension of the second glue injection hole 123, or only the width dimension of the first glue injection hole 122 can be less than the width dimension of the second glue injection hole 123.

[0105] Referring to Figure 7 and Figure 10In an embodiment, the distance between the bottom wall of the first glue injection hole 122 and the bottom of the glue injection tube 120 is 1 / 5 to 3 / 4 of the depth of the mounting groove 210. That is, the distance d2 between the bottom of the first glue injection hole 122 and the bottom of the glue injection tube 120 is 1 / 5 to 3 / 4 of the depth h of the mounting groove 210. In this way, after the glue injection head 100 extends into the mounting groove 210 of the to-be-glued component 200, the first glue injection hole 122 is located in the mounting groove 210 and faces the first surface 211 of the mounting groove 210.

[0106] In this way, when the glue injection head 100 injects the glue 300 into the mounting groove 210 through the first glue injection hole 122, a sufficient amount of glue 300 can be ensured to adhere to the first surface 211, the first surface 211 of the mounting groove 210 can be ensured to be sealed and attached to the to-be-mounted component, and the sealing between the to-be-glued component 200 and the to-be-mounted component can be ensured.

[0107] In the glue injection head 100 of the present application, the bottom of the glue injection tube 120 is closed, the first glue injection hole 122 and the second glue injection hole 123 are arranged on the opposite walls of the glue injection tube 120 according to the extension of the mounting groove 210 of the to-be-glued component 200, in this way, the glue injection head 100 can simultaneously inject glue to the first surface 211 and the second surface 212, the to-be-mounted component can be in sealed contact with the first surface 211 and the second surface 212 without glue overflow through the gap, the sealing between the to-be-glued component 200 and the to-be-mounted component can be ensured, the amount of glue 300 can be reduced, the cost can be reduced, and the product quality and service life can be ensured.

[0108] In an embodiment, the end of the glue injection tube 120 away from the connector 110 is a blocking portion. The blocking portion closes the glue injection channel 121 at the bottom of the glue injection tube 120, or the glue injection tube 120 further has a third glue injection hole, the third glue injection hole penetrates the blocking portion along the height direction and is connected to the glue injection channel 121, and the area of the third glue injection hole is 1 / 10 to 1 / 5 of the area of the first glue injection hole 122.

[0109] The blocking portion is arranged at the bottom of the glue injection tube 120 and blocks the glue injection channel 121 at the bottom of the glue injection tube 120. The blocking portion can completely close the glue injection channel 121, or a third glue injection hole with a small area can be arranged on the blocking portion. In this way, the glue injection tube 120 can not inject glue or inject a small amount of glue at the bottom.

[0110] After the bottom of the glue injection tube 120 injects glue, the glue 300 can be coated on the third surface 214 of the mounting groove 210. In this way, the to-be-mounted component can be fixed to the third surface 214 through the glue 300, and the service life of the to-be-mounted component can be ensured. Of course, according to different models of the to-be-glued component 200 such as a photovoltaic module, no hole or a small third glue injection hole can be arranged on the blocking portion to meet actual needs.

[0111] In an embodiment, the third glue injection hole is circular, elliptical, oblong, rectangular, square or diamond-shaped. It can be understood that the shape of the third glue injection hole is not limited in principle as long as it can inject glue 300 into the glue overflow groove 213.

[0112] In an embodiment, the third glue injection hole is oblong. Of course, in other embodiments of the application, the third glue injection hole can also be rectangular, circular or other regular or irregular shapes.

[0113] Referring to Figures 1 to 7 When the glue head 100 of the application is used to glue the mounting groove 210 of the to-be-glued part 200, the glue 300 enters the glue injection channel 121 of the glue injection pipe 120 through the connecting head 110, and then the glue 300 in the glue injection pipe 120 is injected into the first surface 211 through the first glue injection 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 injection hole 123 and adheres to the second surface 212.

[0114] After the to-be-mounted part is installed into the mounting groove 210 of the to-be-glued part 200, the surface of the to-be-mounted part is pressed into the mounting groove 210 of the to-be-glued part 200 and is pressed against the second surface 212 of the to-be-glued part 200 until the bottom of the to-be-mounted part touches the third surface 214 of the to-be-glued part 200, and the to-be-mounted part stops moving.

[0115] When the glue 300 solidifies, the glue 300 at the first surface 211 and the glue 300 at the second surface 212 can completely seal the to-be-glued part 200 and the to-be-mounted part, and a completely sealed space is formed in the mounting groove 210 of the to-be-glued part 200, and water vapor cannot enter. In addition, the third surface 214 without or with a small amount of glue 300 can seal the gap of the to-be-mounted part, achieving the purpose of reducing cost and increasing efficiency.

[0116] The glue head 100 of the application is provided with the first glue injection hole 122 and the second glue injection hole 123 facing opposite directions on the opposite two pipe walls of the glue injection pipe 120, so that the glue head 100 can simultaneously glue the first surface 211 and the second surface 212, and the to-be-mounted part can be in sealed contact with the first surface 211 and the second surface 212 without glue overflow through the gap, thereby avoiding the lack of glue on the second surface 212 caused by the reduction of glue amount, ensuring the sealing between the to-be-glued part 200 and the to-be-mounted part, reducing the amount of glue 300, reducing the cost, and ensuring the product quality and service life.

[0117] When the frame of the photovoltaic module is glued by the glue head 100, the glue head 100 injects the glue 300 into the first surface 211 through the first glue hole 122 and injects the glue 300 into the second surface 212 through the second glue hole 123, so as to ensure that the first surface 211 and the second surface 212 have enough glue 300.

[0118] When the tempered glass is installed, the glue 300 of the first surface 211 and the second surface 212 is simultaneously extruded by the tempered glass, which further fills the mounting groove 210 of the frame, so that the glue 300 fills the gap of the mounting groove 210 and covers the water-blocking tape. After the glue 300 solidifies, the frame and the tempered glass are tightly adhered, and the glue 300 and the water-blocking tape play a double protection role, which greatly reduces the probability of rainwater introduction.

[0119] Meanwhile, the size of the glue amount can be controlled by the opening size of the first glue hole 122 and the second glue hole 123 and the pressure of the glue pumping structure, so that the glue 300 will not overflow the surface of the to-be-installed part, the cleaning difficulty is reduced, and the to-be-installed part is scratched due to cleaning. The situation is reduced. Moreover, the frame assembling machine does not need to be specially debugged, and the frame can be assembled in a normal state, which reduces the equipment debugging time.

[0120] The present application can use the original glue head 100, that is, the main structure of the glue head 100 is unchanged, and the bottom structure of the glue pipe 120 is changed, and the first glue hole 122 and the second glue hole 123 are opened on the glue pipe 120. In this way, the glue head 100 can be seamlessly compatible with the current glue device.

[0121] Moreover, after the position and area of the first glue hole 122 and the second glue hole 123 are limited, the glue head 100 can more accurately control the glue amount during gluing, reduce the risk of contamination of the glue 300 at 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 are assembled, improve the operation efficiency, and reduce the production cost.

[0122] The present application also provides a glue device, which comprises a glue structure and the glue head 100 of any one of the above embodiments. The glue head 100 is connected to the glue structure through the connecting head 110, and the glue structure injects the glue 300 into the to-be-glued part 200 through the glue head 100. Optionally, the glue structure is a glue pump. Of course, in other embodiments of the present application, the glue structure can also be other structures for delivering the glue 300 to the glue pipe 120.

[0123] 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.

[0124] The above-described embodiments only express several implementation manners of the present 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 present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
