[0002] At present, more and more photovoltaic electronic equipment on the market require overall glue filling in order to meet the requirements of long-term outdoor operation, outdoor waterproofing and product heat dissipation. The glue filling method of electronic equipment is generally to open one or more glue filling holes on the product, so that the potting glue is poured into the electronic equipment through the glue filling holes; at the same time of glue filling, in order to discharge the air inside the electronic equipment, there are usually one or more exhaust holes.

[0003] After the potting is completed, it needs to be left to stand or heated for a long time to solidify the potting glue. Only after the potting glue is solidified can the subsequent production be carried out, such as cleaning the overflowed potting glue and plugging the potting holes and exhaust holes with patches or plugs. In this process, there are many production steps and low efficiency. In addition, because the potting glue itself is oily, the reliability of patches or plugs is poor and the process requirements are high.

[0004] Therefore, how to provide a glue filling device to make the glue filling of products simple and efficient is a technical problem that technicians in this field currently need to solve. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0036] The purpose of the present invention is to provide a glue injection device to make the glue injection of products simple and efficient.

[0037] Please refer to Figures 1 to 3 , to achieve the above purpose, the present invention provides a glue injection device for injecting glue into the housing 100. The glue injection device includes an elastic component 200, a glue injector 300, and an exhaust device 400.

[0038] The elastic component 200 is installed at the first opening 110 and the second opening 120 of the housing 100, and the elastic component 200 is provided with a deformation part 210 that can recover after deformation.

[0039] It can be understood that the housing 100 is provided with a first opening 110 and a second opening 120. Both the first opening 110 and the second opening 120 communicate with the interior of the housing 100. After the elastic component 200 is installed at the first opening 110 of the housing 100, the sealing at the first opening 110 is achieved. Similarly, after the elastic component 200 is installed at the second opening 120 of the housing 100, the sealing at the second opening 120 is achieved.

[0040] The glue injector 300 is provided with a glue injection needle 310 that can penetrate the deformation part 210, so that the glue flows along the glue injection needle 310 into the interior of the housing 100.

[0041] The air exhaust device 400 can penetrate the deformation part 210 to communicate the interior of the housing 100 with the outside.

[0042] Both the glue injection needle 310 and the air exhaust device 400 are hollow tubular structures, and both the glue injection needle 310 and the air exhaust device 400 have relatively sharp pointed parts. By piercing the deformable part 210 that can recover after deformation with the glue injection needle 310 and the air exhaust device 400, the glue injection needle 310 and the air exhaust device 400 are communicated with the interior and the outside of the housing 100.

[0043] It can be understood that the glue injector 300 further includes a storage tank for storing glue. By connecting the storage tank to the end of the glue injection needle 310 away from the pointed part, the glue in the storage tank flows along the glue injection needle 310 into the interior of the housing 100 for subsequent glue filling.

[0044] The glue injector 300 is provided with a glue injection needle 310 that can penetrate the deformation part 210, and the air exhaust device 400 can penetrate the deformation part 210. When gluing, the glue injector 300 and the air exhaust device 400 used pierce the deformation part 210 of the elastic component 200 and enter the interior of the housing 100 for gluing and air exhausting. After the gluing is completed, the glue injector 300 and the air exhaust device 400 are pulled out. Due to the self-rebound closing characteristic of the deformation part 210, the holes pierced by the glue injector 300 and the air exhaust device 400 are automatically closed, so that the potting glue is sealed inside the housing 100 and the potting glue will not overflow. After the gluing is completed, the next production process can be directly carried out without waiting for a long time for curing or heating, making the product gluing simple and efficient.

[0045] In this embodiment, both the first opening 110 and the second opening 120 are stepped holes. The stepped hole includes a first hole with a larger diameter and a second hole with a smaller diameter. The first hole and the second hole are coaxially arranged, and the first hole is located on the side of the second hole away from the interior of the housing 100 to communicate the interior and the outside of the housing 100.

[0046] The first hole which is in line with the axis and is arranged on the outer side of the shell 100 and the second hole which is arranged on the inner side of the shell 100 are connected to realize the connection between the inside and the outside of the shell 100. The first opening 110 and the second opening 120 are both stepped hole structures including the first hole and the second hole, so as to facilitate the processing of the first opening 110 and the second opening 120, and at the same time facilitate the universality of the elastic component 200 installed in the first opening 110 and the second opening 120.

[0047] Among them, the elastic component 200 includes an elastic member, which is provided with a first section 221 that is matched and connected to the first hole, a second section 222 that is passed through the second hole, and a third section 223 that is connected to the second section 222 and located inside the shell 100. The outer diameter of the first section 221 and the outer diameter of the third section 223 are both larger than the outer diameter of the second section 222 and the diameter of the second hole, so that the elastic member can be clamped in the second hole.

[0048] Since the outer diameter of the first section 221 and the outer diameter of the third section 223 are both larger than the outer diameter of the second section 222 and the diameter of the second hole, the first section 221, the second section 222 and the third section 223 form an annular groove structure with the circumferential surface of the second section 222 as the bottom surface, and the annular groove structure is clamped to the second hole to prevent the deformation part 210 of the elastic member from entering the interior of the shell 100 when subjected to the pressure of the glue injection needle 310 and the exhaust device 400. At the same time, it can prevent the friction between the glue injection needle 310 and the deformation part 210 and the friction between the exhaust device 400 and the deformation part 210 from driving the elastic member to detach from the shell 100 when the glue injection needle 310 and the exhaust device 400 are pulled out of the deformation part 210 of the elastic member, thereby ensuring the stable connection of the elastic member relative to the shell 100.

[0049] Furthermore, the first hole is connected to an annular groove 130, which is located on the side of the first hole close to the interior of the shell 100. The first section 221 is provided with an annular first protrusion 224 adapted to the annular groove 130 to increase the adhesion of the elastic member at the first opening 110 and the second opening 120 to prevent the elastic member from moving relative to the shell 100.

[0050] In addition, the second hole is connected to an annular groove 140, which is arranged on the circumferential wall of the second hole at intervals along the axis of the second hole. The circumference of the second section 222 is provided with a circular second protrusion 225 adapted to the annular groove 140. When the annular groove 140 is a whole circular ring, the elastic member can be prevented from moving along its own axial direction. The provision of one or more annular grooves 140 facilitates the stable clamping of the elastic member with the first opening 110 and the second opening 120.

[0051] Taking into account the piercing process of the glue filling needle 310 and the exhaust device 400, the deformation part 210 is arranged in the middle of the second section 222, and the axis of the deformation part 210 is consistent with the axis of the second section 222. A groove 226 is opened in the middle of the first section 221, and the bottom of the groove 226 extends to an end face of the deformation part 210 on the axis of the second section 222. A groove body 227 is opened in the middle of the third section 223, and the groove body 227 extends to the other end face of the deformation part 210 on the axis of the second section 222.

[0052] By arranging the two end faces of the deformation part 210 on the axis of the second section 222 through the sink groove 226 and the groove body 227, the thickness of the deformation part 210 in its own axial direction is reduced while saving materials, so as to facilitate the piercing process of the glue filling needle 310 and the exhaust device 400, and at the same time, it can avoid excessive contact between the glue filling needle 310 and the exhaust device 400 and the deformation part 210 as much as possible, reduce the friction between the glue filling needle 310 and the exhaust device 400 and the deformation part 210 during the process of pulling out the glue filling needle 310 and the exhaust device 400, and also avoid the problem of blockage of the glue filling needle 310 and the exhaust device 400 caused by the deformation part 210.

[0053] In this embodiment, there is an interference fit between the elastic component 200 and the first opening 110, and between the elastic component 200 and the second opening 120 to ensure that the elastic component 200 can seal the first opening 110 and the second opening 120. The specific interference fit between the elastic component 200 and the first opening 110, and between the elastic component 200 and the second opening 120 can be adjusted according to actual conditions.

[0054] The elastic component 200 is made of any elastic material such as rubber, silicone, or plastic, as long as it can achieve the above purpose.

[0055] See also Figure 4 and Figure 5 In another embodiment, the first hole is provided with a plurality of third protrusions 150 and a fourth protrusion 160 located between the third protrusions 150 and the second hole, the third protrusions 150 are evenly arranged along the circumference of the bottom surface of the first hole, the fourth protrusion 160 is an annular protrusion, and the distance between the top of the third protrusion 150 and the bottom surface of the first hole is greater than the distance between the fourth protrusion 160 and the bottom surface of the first hole.

[0056] There may be a plurality of fourth protrusions 160 , and each of the plurality of fourth protrusions 160 is an annular protrusion located between the third protrusion 150 and the second hole.

[0057] The elastic component 200 includes a first seal 230. The first seal 230 includes a deformation part 210 and a limiting part 231 disposed on the outer periphery of the deformation part 210. The limiting part 231 is located in the middle of the deformation part 210 in the axial direction, so that the deformation part 210 forms an embedding part 232 adapted to the second hole and an outer convex part 233 located above the limiting part 231. The limiting part 231 is provided with a first through hole 234 adapted to the third protrusion 150, so that the bottom surface of the limiting part 231 can be attached to the top of the fourth protrusion 160.

[0058] The limiting part 231 is provided with a first through hole 234 corresponding to the third protrusion 150. After aligning the first through hole 234 with the third protrusion 150, the first seal 230 provided with the limiting part 231 is installed into the first hole and the second hole, and one side of the limiting part 231 is attached to the top of the fourth protrusion 160 to achieve the sealing of the second hole. After installation, the side of the limiting part 231 facing away from the fourth protrusion 160 should be flush with the top of the third protrusion 150.

[0059] Among them, the elastic component 200 further includes a second seal 240. The second seal 240 is located in the first hole and fixedly connected to the housing 100. A second through hole 241 adapted to the outer convex part 233 is provided in the middle of the second seal 240, so that the second seal 240 presses the first seal 230.

[0060] By installing the outer convex part 233 into the second through hole 241 in the middle of the second seal 240, the installation of the second seal 240 is realized. At the same time, the second seal 240 is embedded in the first hole to press the first seal 230. The second seal 240 is fixedly connected to the housing 100 by ultrasonic welding or other means, and the first seal 230 is pressed between the housing 100 and the second seal 240, so that the fourth protrusion 160 of the housing 100 and the second seal 240 exert pressure on the first seal 230 to achieve the sealing effect.

[0061] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0062] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
