[0038] The first aspect of the embodiments of the present application provides a glue filling box, such as Figures 1 to 5 As shown, the glue filling box comprises a box body 10 and a cover plate 20;

[0039] The box body 10 has an opening 100, and the box body 10 forms an accommodation space for accommodating a PCB;

[0040] The cover plate 20 is detachably mounted at the opening 100 of the box body 10;

[0041] The first connecting assembly comprises a first connecting piece 11 and a first limiting piece 12, and the second connecting assembly comprises a second connecting piece 13 and a second limiting piece 14, the first connecting piece 11 is used for being connected with the second connecting piece 13 on another box body 10, and the first limiting piece 12 is used for being matched and limited with the second limiting piece 14 on another box body 10.

[0042] The glue filling box provided by the embodiment of the present application can be combined through the first connecting assembly and the second connecting assembly between each glue filling box, modular assembly is realized, the glue filling of the PCB module with different expansion functions can be adapted, and therefore the applicability of the glue filling box is improved.

[0043] In application, the cover plate 20 is detachably mounted at the opening 100 of the box body 10, which includes but is not limited to clamping, plug-in, bonding and the like. It should be noted that the cover plate 20 and the box body 10 are detachably connected when the glue filling operation is not performed, but after the glue filling operation, the cover plate 20 and the box body 10 are generally sealed by the sealing glue, and generally will not be disassembled.

[0044] Specifically, the glue filling box provided by the embodiment of the present application is used in the glue filling and waterproofing of the PCB module, and is particularly suitable for the glue filling of the PCB module with expansion functions, for example, A function module, B function module, C function module and ABC module can be individually placed in the glue filling box provided by the embodiment of the present application, the size of the glue filling box is the smallest box that can adapt to any one of A, B and C modules, that is, A, B and C can be individually placed in the box for glue filling, and the size of the box is the smallest. In one application mode, for example, product function upgrade, B module can be added on the basis of A, and the specific method is as follows: ABC modules are individually glued, when B or C or BC module needs to be added on the basis of A, the required glue filling boxes can be stacked with each other through the structure of the glue filling boxes (connection of the first connecting piece 11 and the second connecting piece 13, limiting and fixing of the first limiting piece 12 and the second limiting piece 14).

[0045] In application, when two or more PCBs are glued, two or more glue filling boxes are required, and in the existing glue filling box, each glue filling box is independent and cannot be assembled, so when unified glue filling is performed, each glue filling box needs to be fixed, and therefore the efficiency is low. When the glue filling boxes provided by the embodiment of the present application are used to simultaneously glue different function PCBs, the first connecting piece 11, the second connecting piece 13, the first limiting piece 12 and the second limiting piece 14 on the glue filling box are matched, and mutual assembly is realized, thereby facilitating glue filling.

[0046] In some embodiments, as shown in FIG. 6, the first connecting assembly and the second connecting assembly are arranged on the same side of the box body 10. Figures 1 to 3As shown, the first connecting piece 11 and the second connecting piece 13 are respectively located on two adjacent side walls of the box body 10. In this way, the assembly is facilitated. The first connecting piece 11 is a slide buckle, and the second connecting piece 13 is a clamping plate. The clamping plate is in clamping connection with the slide buckle. As shown in Figure 1 and Figure 2 As shown, the slide buckle has a clamping groove in the middle, and the clamping plate is matched with the clamping groove in the middle of the slide buckle, so as to realize the assembly of multiple glue filling boxes. In other embodiments, the first connecting piece 11 and the second connecting piece 13 can also be located on two non-adjacent side walls of the box body 10, and the specific design can be set according to actual needs.

[0047] It should be noted that the clamping connection of the first connecting piece 11 and the second connecting piece 13 is a limiting and fixing in the thickness direction of the glue filling box, and in order to strengthen the connection firmness between multiple glue filling boxes, two groups of first connecting pieces 11 are symmetrically arranged on each box body 10, and two groups of second connecting pieces 13 are symmetrically arranged for the same reason. In this way, the limiting and fixing in the width direction of the glue filling box can be realized. The thickness direction of the glue filling box refers to the X direction in the figure, the width direction of the glue filling box refers to the Y direction in the figure, and the length direction of the glue filling box refers to the Z direction in the figure. The above directions are for the convenience of understanding the technical solutions of the present application, and should not be understood as a limitation on the protection scope of the present application.

[0048] In some embodiments, as shown in Figures 1 to 3 As shown, the box body 10 is also provided with a sliding groove 101 on the side close to the clamping plate, and the sliding groove 101 is used for sliding the slide buckle on another glue filling box, so as to realize the clamping connection of the slide buckle and the clamping plate. In this way, the sliding groove 101 plays a guiding role. When two or more glue filling boxes are assembled, the clamping plate is not easy to directly clamp the clamping groove of the slide buckle, so the sliding groove 101 is arranged on the box body 10 to guide the clamping plate and the slide buckle.

[0049] In some embodiments, as shown in Figure 2 As shown, the middle part of the first limiting piece 12 is recessed inward to form a recess 120, and the second limiting piece 14 is arranged at the end of the sliding groove 101 away from the second connecting piece 13. The second limiting piece 14 is a protrusion, and the protrusion is matched with the recess 120 to limit and fix two glue filling boxes. In this way, the matching of the first limiting piece 12 and the second limiting piece 14 limits and fixes the assembled glue filling box in the length direction, so as to comprehensively strengthen the connection strength of the assembled glue filling box.

[0050] In some embodiments, as shown in Figure 2As shown, the first limiting member 12 is arranged side by side and spaced apart from the first connecting member 11, specifically, the first limiting member 12 and the first connecting member 11 are arranged along the length direction of the glue filling box, so as to facilitate the assembly of multiple glue filling boxes without affecting each other. The second limiting member 14 is arranged side by side and spaced apart from the second connecting member 13. Specifically, the second limiting member 14 and the second connecting member 13 are arranged along the length direction of the glue filling box, so as to facilitate the assembly of multiple glue filling boxes without affecting each other.

[0051] In some embodiments, as shown in Figures 1 to 3 As shown, the outer side wall of the box body 10 is provided with a let go slot 102. The existence of the let go slot 102 can facilitate the movement and removal of the glue filling box; especially when multiple assembled glue filling boxes need to be moved, the let go slot 102 provides operation space, facilitating the taking and moving. In a preferred embodiment, the let go slot 102 is arranged on the corner of the box body 10, and is arranged side by side and spaced apart from the sliding groove 101. In this way, the processing of the let go slot 102 and the sliding groove 101 is facilitated.

[0052] In some embodiments, as shown in Figure 4 As shown, a plurality of limiting columns 15 are arranged in the box body 10, and the plurality of limiting columns 15 are arranged between the adjacent side walls of the box body 10. The existence of the limiting column 15 can limit and fix the PCB located in the box body 10. Further, as shown in Figure 2 、 Figure 4 and Figure 5 As shown, the side of the cover plate 20 close to the accommodating space is provided with a positioning column 21. The positioning column 21 can further strengthen the limiting and fixing of the PCB.

[0053] In some embodiments, as shown in Figure 5 As shown, the cover plate 20 is provided with a wire outlet hole 200 and a glue filling hole 201. The wire outlet hole 200 is used to lead the wires or connectors on the PCB out of the box, so as to be connected with other external devices. It ensures that the wires will not be sealed during the glue filling process, while keeping the wires neat and safe. The glue filling hole 201 is the entrance for the glue filling material to enter the inside of the glue filling box. It ensures that the glue filling material can flow smoothly into the box to cover all parts of the PCB.

[0054] In application, there are usually sealing measures such as rubber rings or sealing glue around the wire outlet hole 200 to prevent glue filling material from leaking from the hole. It ensures the sealing of the inside of the glue filling box, prevents moisture and dust from entering, and improves the protection effect of the PCB. Specifically, organic silicone gel or polyurethane transparent sealant is used, which has good chemical stability and insulation, moisture resistance, shock resistance, weather resistance, moderate viscosity, so that the PCB truly achieves the purpose of dust and moisture proofing, and ensures the functional reliability of the PCB;

[0055] During the glue filling process, the glue filling hole 201 can also serve as an exhaust hole to help expel the air in the box and reduce the generation of air bubbles. Reducing air bubbles can improve the uniformity and quality of glue filling and ensure that the PCB is fully protected. After glue filling is completed, the glue filling hole 201 needs to be closed to ensure internal sealing. Preventing glue from seeping out of the hole, maintaining the overall aesthetic and protective effect. When the glue filling box fills and seals a soft silicone-based glue, the cover plate 20 can limit the PCB to prevent the pull line from pulling the PCB out.

[0056] In some embodiments, as shown in Figure 2 The box body 10 is not adjacent to the two side walls, and a buckle structure for fixing the elastic sheet is further provided. The buckle structure includes:

[0057] The clamping block 16 is arranged on the side wall of the box body 10, and the clamping block 16 is used for plug-in cooperation with the clamping hole on the elastic sheet.

[0058] The protruding strips 17 are distributed on the box body 10 along the two sides of the clamping block 16, and the protruding strips 17 are used for strengthening the connection and fixation between the clamping block 16 and the elastic sheet. In this way, the glue filling box can be fixed on the elastic sheet through the buckle to ensure the stability and accuracy of the PCB during the glue filling process. Since the elastic sheet has resilience and the size of the elastic sheet may vary, the glue filling box may still shake even when it is fixed through the clamping block 16. However, the protruding strips 17 can prevent the glue filling box from shaking and improve the installation stability of the glue filling box.

[0059] In some embodiments, as shown in Figure 2 The box body 10 is not adjacent to the two side walls, and a buckle structure for fixing the elastic sheet is further provided. The buckle structure includes:

[0060] The protruding strips 17 are distributed on the box body 10 along the two sides of the clamping block 16, and the protruding strips 17 are used for strengthening the connection and fixation between the clamping block 16 and the elastic sheet. In this way, the glue filling box can be fixed on the elastic sheet through the buckle to ensure the stability and accuracy of the PCB during the glue filling process. Since the elastic sheet has resilience and the size of the elastic sheet may vary, the glue filling box may still shake even when it is fixed through the clamping block 16. However, the protruding strips 17 can prevent the glue filling box from shaking and improve the installation stability of the glue filling box.

[0061] The glue filling box provided by the embodiments of the present application has the following main advantages:

[0062] Convenient modular assembly: Due to the structural design of the glue filling box, multiple glue filling boxes can be assembled with each other to realize modular stacking.
