Description

Technical Field

[0001] This utility model relates to the field of adhesive application tooling technology, specifically to an adhesive application tooling for hot riveting columns of an energy storage box. Background Technology

[0002] High-voltage energy storage systems are a crucial component of modern power grid peak shaving, renewable energy grid integration, and microgrids. One of their core components—the energy storage tank and its cover—not only provides mechanical protection and environmental isolation for the internal battery modules and power electronic equipment, but also maintains reliable structural strength, electrical insulation, and electromagnetic shielding performance under harsh conditions such as high voltage, high current, wide temperature range, and chemical corrosion. To ensure the stable fixation of complex components inside the high-voltage tank cover (such as battery modules, BMS (Battery Management System), and high-voltage interconnecting cables), hot riveting or bolt assembly methods are typically used to clamp and position each functional unit. However, with the increasing irregular shapes of energy storage tanks and the growing density of internal assembly, relying solely on the mechanical friction of fasteners can easily lead to loosening of screws due to vibration or thermal cycling stress, resulting in safety hazards such as poor electrical contact, short circuits, or even thermal runaway.

[0003] To improve the reliability of fastener connections, the industry often applies structural adhesive during hot riveting or bolt assembly to enhance bond strength and also provides vibration isolation and dust sealing. However, in actual production, assembly workers typically apply the adhesive manually by applying it by hand or brushing it on.

[0004] 1. Due to the varied shapes and limited internal space of the boxes, it is difficult to accurately apply the glue by hand with a glue gun, often resulting in insufficient glue, missed application, or glue overflow onto surrounding electronic components.

[0005] 2. After the glue overflows, the residual glue needs to be cleaned up one by one, and the glue layer is difficult to remove after it has hardened, which not only prolongs the assembly cycle, but also increases the rework cost;

[0006] 3. The manual gluing process has poor repeatability, and the thickness and coverage of the glue layer are inconsistent between different operators, which affects the subsequent temperature control and electrical insulation of the enclosure.

[0007] 4. With the increase in annual production of energy storage systems, the low efficiency of manual gluing has become a key bottleneck restricting the steady improvement of assembly capacity and quality.

[0008] Therefore, there is an urgent need for a special gluing tool that can accurately position the hot riveting columns inside the high-voltage energy storage tank cover, control the amount of glue, and is easy to operate and highly repeatable. This tool can solve the technical defects of the existing manual gluing process, such as easy glue overflow, difficulty in controlling the amount of glue, and time-consuming cleaning, significantly improve the efficiency of gluing operations and assembly quality, and ensure the safety and reliability of the high-voltage energy storage system. Utility Model Content

[0009] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hot riveting and gluing fixture for energy storage tanks. The fixture has a reasonable structural design, can accurately position the hot riveting columns inside the high-voltage energy storage tank cover, has controllable glue application, is easy to operate, has high repeatability, and is highly practical.

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a glue applicator for hot riveting columns of an energy storage box, comprising a glue applicator and a limiting ring. The limiting ring is installed at the bottom of the hot riveting column or bolt, and the glue applicator is installed at the top of the hot riveting column or bolt for positioning. The glue applicator includes a positioning hole and a glue outlet hole. The interior of the glue applicator is provided with a positioning hole that connects to the hot riveting column or bolt. A structural adhesive storage cavity and a main glue inlet hole are sequentially provided on one side of the positioning hole. Four glue outlet holes are provided on the inner wall of the structural adhesive storage cavity.

[0011] Preferably, the diameter of the dispensing hole is 1.5 mm.

[0012] Preferably, the glue head fixture is a photosensitive resin glue head fixture.

[0013] The beneficial effects of this utility model are as follows: The segmented glue head tooling (photosensitive resin 3D printing) of this utility model, through the progressive design of main glue inlet cavity → storage cavity → four-way diversion hole, ensures that the structural glue evenly covers the surface of the rivet / bolt, avoiding glue overflow or breakage; the silicone limiting ring has dual functions: it precisely raises and controls the glue brushing height, and during demolding, it uses flexible deformation to scrape the bottom glue upwards, achieving uniform axial glue layer thickness; the glue is evenly coated without bubbles or accumulation, effectively avoiding glue layer cracking or sealing failure during subsequent assembly.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Reference Figure 1-2The specific embodiment adopts the following technical solution: a glue applicator for hot riveting columns of an energy storage box, including a glue applicator 1 and a limiting ring 2. The limiting ring 2 is installed at the bottom of the hot riveting column or bolt, and the glue applicator 1 is installed at the top of the hot riveting column or bolt for positioning. The glue applicator 1 includes a positioning hole 3 and a glue outlet hole 4. The glue applicator 1 has a positioning hole 3 inside that is connected to the hot riveting column or bolt. A structural adhesive storage cavity 5 and a main glue inlet hole 6 are arranged sequentially on one side of the positioning hole 3. Four glue outlet holes 4 are arranged on the inner wall of the structural adhesive storage cavity 5.

[0019] It is worth noting that the diameter of the dispensing hole 4 is 1.5 mm.

[0020] Furthermore, the aforementioned glue head fixture 1 is a photosensitive resin glue head fixture.

[0021] This specific embodiment of the hot riveting post adhesive application fixture mainly consists of an adhesive applicator and a limiting ring. The adhesive applicator is made of photosensitive resin material through 3D printing. The adhesive outlet cavity of the adhesive applicator adopts a segmented design. The structural adhesive enters the storage cavity along the main adhesive inlet cavity, and then flows to the surface of the bolt or hot riveting post through four small holes on the inner wall of the storage cavity. The limiting ring is made of silicone material. Its main functions are twofold: first, to raise the post (the adhesive application height of the riveting post is required), and second, to evenly apply the structural adhesive from the bottom upwards when the post is removed upwards.

[0022] The specific operation method of this embodiment is as follows: first, put the limiting ring on the bottom of the hot riveting post or bolt, then install the glue head fixture on the top of the riveting post or bolt for positioning, then insert the structural glue tube into the tool hole at the top of the glue head for glue injection, and finally remove the glue head fixture and the limiting ring to complete the glue application.
