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

[0004] However, after the water-blocking adhesive tape is pasted, the glue cannot overflow to the A surface through the gap due to the influence of the water-blocking adhesive tape, resulting in no glue in the overflow groove of the A surface, which causes the glue on the C surface to be unable to overflow to the A surface. After the heterojunction cell module is packaged, the sealing performance is insufficient, and long-term exposure to rain and sunlight causes water vapor to penetrate around the module, which reduces the power generation efficiency of the cell piece and even causes the cell piece to fail. INVENTION CONTENTS

[0014] The second glue injection hole is at least partially located in the range of the glue overflow groove.

[0015] In an embodiment of the present application, the second glue injection hole is towards the inner wall of the connector, and does not exceed the surface of the part to be glued.

[0016] In an embodiment of the present application, the size of the second glue injection hole along the height direction of the glue injection pipe is 1 / 7-1 / 4 of the depth of the mounting groove.

[0017] And / or, the size of the second glue injection hole along the width direction of the glue injection pipe is 1 / 3-3 / 2 of the width of the glue injection pipe.

DETAILED DESCRIPTION

[0038] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are 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 a variety of ways other than those described herein without departing from the spirit of the present application, and it is understood that similar modifications can be made by those skilled in the art in the light of the foregoing description. Therefore, it is not intended to limit the present application to the following specific embodiments disclosed in the following description.

[0039] In the description of the present application, it should be understood that if 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 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.

[0040] In addition, if these terms "first", "second" appear, 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 the 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 present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0041] In the present application, unless otherwise specifically defined and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be understood in a broad sense. 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 specifically 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.

[0042] In the present application, unless specifically stated and limited otherwise, if there is a description of a first feature "on" or "under" a second feature, etc., 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 "on", "above" and "over" the second feature can be that the first feature is directly above or obliquely above the second feature, or only means that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only means that the first feature is lower in horizontal height than the second feature.

[0043] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can be a mediating element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a mediating 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.

[0044] It can be understood that at present, during the assembling process of the heterojunction battery assembly, sealing glue needs to be injected 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 after extrusion, the glue overflows 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 penetrating.

[0045] However, after the water-blocking adhesive tape is pasted, due to the influence of the water-blocking adhesive tape, the glue cannot overflow to the A surface through the gap, causing no glue in the overflow groove of the A surface, resulting in that the glue on the C surface cannot overflow to the A surface, and after the heterojunction battery assembly is packaged, the sealing performance is insufficient, and after long-term outdoor rain and sunshine, water vapor penetrates around the assembled component, the power generation efficiency of the battery piece is reduced, and even the battery piece is invalid.

[0046] Therefore, referring to Figures 1 to 3 The present application provides a new glue injection head 100. Figure 1 The schematic view of the glue injection head 100 of an embodiment of the present application from one viewing angle, Figure 2 The schematic view of the glue injection head 100 from another viewing angle, Figure 1 The front view of the glue injection head 100. Figure 3 The front view of the glue injection head 100. Figure 1 The front view of the glue injection head 100.

[0047] The dispensing head 100 is used in a dispensing device (not shown) to inject adhesive into the mounting groove 210 of the part to be dispensed 200. The edge of the part to be installed (not shown) is set in the mounting groove 210. The adhesive is used to achieve a sealed connection between the part to be dispensed 200 and the part to be installed, ensuring a high degree of sealing at the connection.

[0048] In this application, injecting adhesive into the mounting groove 210 of the part to be adhesiveted 200 is called adhesive application. The following description of the adhesive injection head 100 into the mounting groove 210 will only be used as an example of adhesive application. Optionally, the adhesive may be silicone or other adhesives capable of bonding and sealing.

[0049] In this embodiment, the component to be glued 200 is the frame of the photovoltaic module, and the component to be installed is tempered glass. Typically, the edge of the tempered glass of the photovoltaic module is installed within the frame. After injecting adhesive into the frame, the frame and the tempered glass are sealed together by the adhesive, thereby ensuring an effective seal for the photovoltaic module and preventing moisture from entering the inside of the photovoltaic module, thus ensuring the performance of the photovoltaic module.

[0050] Of course, in other embodiments of this application, the component to be glued 200 may also be other structures or parts that require glue sealing, and the component to be installed may also be other parts that need to be installed onto the component to be glued 200. This application only uses the example of the frame of the photovoltaic module being the component to be glued 200 and the tempered glass of the photovoltaic module being the component to be installed as an example for illustration.

[0051] To better illustrate the structure of the glue applicator 100, the structure of the part to be glued 200 will be described first. (See also...) Figure 4 and Figure 5 , Figure 4 for Figure 1 The diagram shows the mating of the glue applicator 100 and the part 200 to be glued. Figure 5 for Figure 4 The image shows a side perspective view of the glue applicator 100 mating with the part to be glued 200. The part to be glued 200 is generally arranged in a strip shape.

[0052] The part 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 facing each other, such as Figure 4 and Figure 5 As shown. When the glue applicator 100 applies glue to the mounting groove 210, it applies glue to the first surface 211 and the second surface 212 respectively.

[0053] When the glue head 100 of the present application applies glue to the mounting groove 210 of the to-be-glued part 200, the glue can be injected to the first surface 211 and the second surface 212 respectively. After the to-be-mounted part is mounted to the mounting groove 210 of the to-be-glued part 200, the first surface 211 and the second surface 212 can be sealedly connected through the glue and the to-be-mounted part, without glue overflow through the gap, so that the first surface 211 and the second surface 212 have sufficient glue, and the sealing between the to-be-mounted part and the to-be-glued part 200 is ensured to avoid water vapor from the outside.

[0054] The specific structure of the glue head 100 of an embodiment will be introduced below.

[0055] Referring to Figures 1 to 5 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 that is in communication with the connecting head 110. The glue pipe 120 has a first glue hole 122 that is arranged obliquely at the end away from the connecting head 110. The side surface of the glue pipe 120 has a second glue hole 123 that penetrates through the thickness direction of the glue pipe 120. The first glue hole 122 and the second glue hole 123 are both in communication with the glue channel 121. The first glue hole 122 and the second glue hole 123 are oppositely directed, the first glue hole 122 can be directed to the first surface 211, and the second glue hole 123 can be directed to the second surface 212.

[0056] The present application is described based on the up-down, left-right, front-back directions of the glue head 100. As shown in Figures 1 to 3 The height direction of the glue head 100 is the up-down direction and the top-bottom direction of the glue head 100. The left-right direction of the glue head 100 is the width direction of the glue head 100. The front-back direction of the glue head 100 is the thickness direction of the glue head 100.

[0057] The connecting head 110 is a connecting component 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. The bottom of the connecting head 110 is connected to the glue pipe 120. The connecting head 110 and the glue pipe 120 are hollowly arranged. The hollow cavity of the glue head 100 is the glue channel 121. The glue structure delivers glue to the glue channel 121 through the connecting head 110, and then the glue is injected into the mounting groove 210 through the glue head 100.

[0058] The end of the glue pipe 120 away from the connecting head 110 is referred to as the bottom of the glue pipe 120. The bottom of the glue pipe 120 has the first glue hole 122 that penetrates through the glue channel 121 along the height direction. The first glue hole 122 is arranged obliquely. The side surface of the glue pipe 120 also has the second glue hole 123 that penetrates through the thickness direction of the glue pipe 120. The second glue hole 123 is also in communication with the glue channel 121.

[0059] Moreover, the first glue injection hole 122 and the second glue injection hole 123 are opposite to each other. That is, the first glue injection hole 122 and the second glue injection hole 123 are opposite to each other in the thickness direction of the glue injection pipe 120. After the bottom of the glue injection head 100 is inserted into the mounting groove 210, the first glue injection hole 122 is opposite to the first surface 211, and the second glue injection hole 123 is opposite to the second surface 212.

[0060] When the glue injection head 100 injects glue into the mounting groove 210, the glue in the glue injection pipe 120 enters the mounting groove 210 through the first glue injection hole 122 and adheres to the first surface 211, and the glue in the glue injection pipe 120 also enters the mounting groove 210 through the second glue injection hole 123 and adheres to the second surface 212.

[0061] In this way, the glue injection head 100 can simultaneously inject glue into the first surface 211 and the second surface 212, and the first surface 211 and the second surface 212 are both provided with glue. After the edge of the to-be-mounted member is mounted into the mounting groove 210, the two surfaces of the to-be-mounted member are respectively attached to the first surface 211 and the second surface 212 through the glue, thereby ensuring the sealing between the to-be-glued member 200 and the to-be-mounted member.

[0062] In this way, the second surface 212 does not need to be connected to the to-be-mounted member through glue overflow of the first surface 211, thereby avoiding the situation that the second surface 212 is not provided with glue, and the glue injection head 100 can ensure that the first surface 211 and the second surface 212 are both provided with sufficient glue, thereby realizing effective sealing between the to-be-glued member 200 and the to-be-mounted member and effectively preventing water vapor from entering from the surrounding.

[0063] The glue injection head 100 of the above embodiment is provided with the first glue injection hole 122 and the second glue injection hole 123 opposite to each other on the glue injection pipe 120. After glue is injected into the mounting groove 210 of the to-be-glued member 200, the glue injection head 100 injects glue into the first surface 211 through the first glue injection hole 122 and injects glue into the second surface 212 through the second glue injection hole 123. In this way, the glue injection head 100 can simultaneously inject glue into the first surface 211 and the second surface 212 of the mounting groove 210, without glue overflow through the gap, thereby ensuring that the first surface 211 and the second surface 212 are both provided with sufficient glue and ensuring the sealing between the to-be-glued member 200 and the to-be-mounted member.

[0064] Referring to Figures 1 to 3 In an embodiment, the glue injection pipe 120 at least includes opposite first plate body 125 and second plate body 126, the first plate body 125 is opposite to the first surface 211, and the second plate body 126 is opposite to the second surface 212. In the height direction of the glue injection pipe 120, the size of the first plate body 125 is smaller than the size of the second plate body 126, and the first glue injection hole 122 is formed to be inclined. The second plate body 126 is provided with the second glue injection hole 123.

[0065] Referring toFigure 1 and Figure 2 The glue applicator 120 has a first plate 125 and a second plate 126 opposite each other in the thickness direction. The dimension of the first plate 125 in the height direction is smaller than the dimension of the second plate 126 in the height direction. In this way, the bottom of the first plate 125 and the bottom of the second plate 126 can form an inclined first glue applicator hole 122, which faces the first surface 211.

[0066] The second plate 126 has a second glue-applying hole 123 that extends through the thickness direction of the glue-applying tube 120. In this way, the first glue-applying hole 122 and the second glue-applying hole 123 are arranged in opposite ways so that the first glue-applying hole 122 can apply glue to the first surface 211 and the second glue-applying hole 123 can apply glue to the second surface 212.

[0067] In this embodiment, the glue applicator 120 is generally square. Of course, in other embodiments of this application, the glue applicator 120 may also be circular, polygonal, or other shapes.

[0068] See Figures 1 to 3 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.

[0069] 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 are an integral structure.

[0070] See Figures 1 to 7 In one embodiment, the end of the glue applicator 120 furthest from the connector 110 is the glue applicator end 124. The second glue applicator hole 123 is close to the inner wall of the glue applicator end 124, and the distance between the second glue applicator hole 123 and the glue applicator end 124 is less than the depth of the mounting groove 210. Figure 6 for Figure 5 The enlarged view of the glue applicator 100 and the part 200 to be glued at point A is shown. Figure 7 for Figure 4 The diagram shows a portion of the glue applicator 100 being removed from the mounting slot 210.

[0071] The bottom of the adhesive applicator 100 is the adhesive applicator end 124. The adhesive applicator 100 applies adhesive to the first surface 211 of the mounting groove 210 through the first adhesive applicator hole 122 of the adhesive applicator end 124, and applies adhesive to the second surface 212 of the mounting groove 210 through the second adhesive applicator hole 123 on the side. Figure 4 and Figure 5It can be seen that the second glue injection hole 123 is located in the range of the mounting groove 210. Figure 6 In order to show the second glue injection hole 123 of the glue injection head 100, the second glue injection head 100 is partially removed from the mounting groove 210.

[0072] As shown in Figure 5 and Figure 6 , the distance between the bottom wall of the second glue injection hole 123 and the glue injection end 124 is d1, the depth of the mounting groove 210 is h, and the distance h1 from the bottom wall of the second glue injection hole 123 to the glue injection end 124 is less than the depth h of the mounting groove 210.

[0073] In this way, after the glue injection head 100 is inserted into the mounting groove 210, the second glue injection hole 123 can be located in the depth range of the mounting groove 210. When the glue injection head 100 injects glue through the second glue injection hole 123, the second glue injection hole 123 can deliver glue into the mounting groove 210, so that the glue can adhere to the second surface 212, facilitating the sealed connection between the glue injection part 200 and the mounting part.

[0074] Referring to Figure 5 and Figure 6 , in an embodiment, the inner wall of the second glue injection hole 123 close to the glue injection end 124 is 1 / 5-3 / 4 of the depth of the mounting groove 210 away from the glue injection end 124. That is, the distance d1 between the bottom of the second glue injection hole 123 and the glue injection end 124 is 1 / 5-3 / 4 of the depth h of the mounting groove 210. In this way, after the glue injection head 100 is inserted into the mounting groove 210 of the glue injection part 200, the second glue injection hole 123 is located in the mounting groove 210 and faces the second surface 212 of the mounting groove 210.

[0075] In this way, when the glue injection head 100 injects glue into the mounting groove 210 through the second glue injection hole 123, it can ensure that a sufficient amount of glue adheres to the second surface 212, ensuring that the second surface 212 of the mounting groove 210 can be sealed and fitted to the mounting part, and ensuring the sealing between the glue injection part 200 and the mounting part.

[0076] Referring to Figures 4 to 7 , in an embodiment, the mounting groove 210 further has a glue overflow groove 213 recessed on the second surface 212. The second glue injection hole 123 is at least partially located in the range of the glue overflow groove 213. The glue overflow groove 213 is recessed above the second surface 212.

[0077] Generally, the glue overflow groove 213 is used to accommodate excess glue. If glue is only injected on the first surface 211 of the mounting groove 210, there may be little or even no glue on the second surface 212 and the glue overflow groove 213, affecting the sealed connection between the glue injection part 200 and the mounting part.

[0078] To this end, the second glue hole 123 is arranged on the glue head 100 and faces the second surface 212, and the second glue hole 123 is at least partially located in the range of the glue overflow groove 213. In this way, when the glue head 100 glues through the second glue hole 123, part of the glue enters the mounting groove 210 and adheres to the second surface 212, and part of the glue enters the glue overflow groove 213. In this way, the to-be-mounted part 200 can be sealed and bonded by the glue in the second surface 212 and the glue overflow groove 213.

[0079] As shown in Figure 5 and Figure 6 , in the embodiment, the second glue hole 123 partially corresponds to the glue overflow groove 213 and partially corresponds to the second surface 212. In this way, glue can be applied to the glue overflow groove 213 and the second surface 212, respectively. Of course, in other embodiments of the present application, the second glue hole 123 can also completely correspond to the glue overflow groove 213.

[0080] Referring to Figures 4 to 6 , in an embodiment, the second glue hole 123 faces the inner wall of the connecting head 110 and does not exceed the surface of the to-be-glued part 200. That is, the top wall of the second glue hole 123 is lower than the top surface of the to-be-glued part 200. That is, the second glue hole 123 is located below the top surface of the to-be-glued part 200, and the second glue hole 123 will not be exposed to the top surface of the to-be-glued part 200.

[0081] In this way, when the glue head 100 glues the second surface 212 through the second glue hole 123, the glue will not overflow the mounting groove 210, and then will not move to the surface of the to-be-mounted part and the to-be-glued part 200, reducing the difficulty of cleaning and reducing damage to the to-be-mounted part caused by cleaning.

[0082] Referring to Figures 1 to 3 , Figure 6 , Figure 8 and Figure 9 , in an embodiment, the size of the second glue hole 123 in the height direction of the glue pipe 120 is 1 / 7-1 / 4 of the depth of the mounting groove 210. Figure 8 For Figure 1 the rear view of the glue head 100, Figure 9 for Figure 8 the partial enlarged view of the glue head 100 at B.

[0083] The size d2 of the second glue hole 123 in the height direction is the opening size of the second glue hole 123 in the height direction. The present application limits the size d2 of the second glue hole 123 in the height direction to be 1 / 7-1 / 4 of the depth h of the mounting groove 210. In this way, the second glue hole 123 can cover part of the mounting groove 210 in the height direction, so that the second glue hole 123 can deliver a sufficient amount of glue to the second surface 212.

[0084] Referring to Figures 1 to 3 , Figure 6 , Figure 8 and Figure 9 , in an embodiment, the size of the second glue hole 123 along the width direction of the glue pipe 120 is 1 / 3~3 / 2 of the width of the glue pipe 120. The size d3 of the second glue hole 123 along the width direction of the glue pipe 120, i.e. the opening size of the second glue hole 123 along the width direction.

[0085] The application limits the size d3 of the second glue hole 123 along the width direction to be 1 / 3~3 / 2 of the width of the glue pipe 120. In this way, the second glue hole 123 can cover part of the mounting groove 210 in the height direction, so that the second glue hole 123 can deliver a sufficient amount of glue to the second surface 212.

[0086] The application limits the height and width of the second glue hole 123, i.e. the opening size of the second glue hole 123. In this way, the amount of glue injected by the second glue hole 123 to the second surface 212 can be ensured. At the same time, the opening size of the second glue hole 123 can be adjusted to adjust the amount of glue injected to the second surface 212.

[0087] Referring to Figure 1 , Figure 2 , Figure 8 and Figure 9 , in the embodiment, the shape of the second glue hole 123 is oblong. Of course, in other embodiments of the application, the second glue hole 123 can also be in the shape of an ellipse, a circle, a square, or other regular or irregular shapes, as long as it can inject glue to the second surface 212.

[0088] Referring to Figure 1 , Figure 3 , Figure 8 and Figure 9 , in an embodiment, the first glue hole 122 and the second glue hole 123 partially overlap along the height direction of the glue pipe 120. In the height direction of the glue pipe 120, the first glue hole 122 and the second glue hole 123 partially overlap.

[0089] The first glue hole 122 is inclinedly arranged, and the lower part of the second glue hole 123 communicates with the upper part of the first glue hole 122. In this way, during glue injection, the glue in the glue channel 121 can enter the first glue hole 122 and the second glue hole 123 at the same time, and the situation that the glue is only injected into the mounting groove 210 through the second surface 212 can be avoided, thereby ensuring the synchronization of glue injection to the first surface 211 and the second surface 212.

[0090] The glue head 100 of the present application is provided with the first glue hole 122 and the second glue hole 123 on the glue pipe 120, which are opposite to each other. After injecting the glue into the installation groove 210 of the to-be-glued member 200, the glue head 100 injects the glue into the first surface 211 through the first glue hole 122 and injects the glue 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. When the to-be-installed member is installed, the glue of the first surface 211 and the second surface 212 is simultaneously extruded by the to-be-installed member, which further fills the installation groove 210 of the to-be-glued member 200, so that the glue fills the gap of the installation groove 210 and the overflow groove 213, and covers the waterproof adhesive tape at the same time. After the glue solidifies, the to-be-glued member 200 and the to-be-installed member are tightly adhered, and the glue and the waterproof adhesive tape play a double protection role, which greatly reduces the probability of rainwater introduction.

[0091] When the glue head 100 of the present application is used to glue the frame of the photovoltaic module, the glue head 100 injects the glue into the first surface 211 through the first glue hole 122 and injects the glue 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. When the tempered glass is installed, the glue of 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 fills the gap of the installation groove 210 and the overflow groove 213, and covers the waterproof adhesive tape at the same time. After the glue solidifies, the frame and the tempered glass are tightly adhered, and the glue and the waterproof adhesive tape play a double protection role, which greatly reduces the probability of rainwater introduction.

[0092] Meanwhile, the size of the glue amount can be controlled by the opening size of the second glue hole 123 and the pressure of the glue pumping structure, so that the glue amount is controllable and the glue will not overflow to the surface of the to-be-installed member, the cleaning difficulty is reduced, and the scratch of the to-be-installed member caused by cleaning the to-be-installed member 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.

[0093] The present application also provides a glue injection device, which comprises a glue injection structure and the glue head 100 of any one of the above embodiments. The glue head 100 is connected to the glue injection structure through the connecting head 110, and the glue injection structure injects the glue into the to-be-glued member 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 to the glue pipe 120.

[0094] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
