Description

Energy storage box body hot riveting post rubber coating frock Technical Field The utility model relates to the technical field of gluing tools, in particular to a gluing tool for a hot riveting column of an energy storage box body. Background The high-voltage energy storage system is used as an important component of scenes such as peak shaving of a modern power grid, renewable energy grid connection, micro-grid and the like, and one of core components, namely the energy storage box body and the box cover thereof, not only bears the mechanical protection and environmental isolation of an internal battery module and power electronic equipment, but also maintains reliable structural strength, electrical insulation and electromagnetic shielding performance under severe working conditions such as high voltage, high current, wide temperature, chemical corrosion and the like. In order to ensure the stable fixation of complex components (such as a battery module, a BMS (battery management system), a high-voltage interconnection cable, etc.) inside the high-voltage tank cover, each functional unit is usually clamped and positioned by adopting a hot riveting column or bolt assembly mode. However, as the energy storage box body is shaped and the internal assembly density is continuously improved, the screw loosens due to vibration or thermal cycle stress easily due to mechanical friction force which is simply dependent on a fastener, so that potential safety hazards such as poor electrical contact, short circuit and even thermal runaway are caused. In order to improve the connection reliability of the fastener, structural adhesive is often coated in the assembly process of the hot riveting column or the bolt to enhance the bonding strength, and the hot riveting column or the bolt has the functions of vibration resistance, sealing and dust prevention. However, in actual production, an assembler generally performs the operations of manually dispensing or brushing the glue: 1. The box body is changeable in shape and narrow in internal space, the handheld dispensing gun is difficult to accurately position, and the phenomena of insufficient glue quantity, missing coating or overflow of glue solution to peripheral electronic elements often occur; 2. the residual glue is required to be cleaned one by one after glue overflow, and the glue layer is difficult to remove after solidification, so that the assembly period is prolonged, and the reworking cost is increased; 3. The manual gluing process is poor in repeatability, and the thickness and coverage area of the glue layer generated among different operators are inconsistent, so that the temperature control and electrical insulation effects of the subsequent box body are affected; 4. with the increase of annual output of energy storage systems, the inefficiency of manual gluing has become a key bottleneck restricting the steady increase of assembly productivity and quality. Therefore, a special gluing tool which can be used for accurately positioning a hot riveting column in a high-pressure energy storage box cover, is controllable in glue quantity, is simple and convenient to operate and is high in repeatability is needed, so that the technical defects of easiness in glue overflow, difficulty in glue quantity control, time consumption in cleaning and the like in the existing manual glue dispensing process are overcome, the gluing operation efficiency and the assembly quality are remarkably improved, and the safety and the reliability of a high-pressure energy storage system are ensured. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide the hot riveting column gluing tool for the energy storage box body, which has reasonable structural design, can accurately position the hot riveting column in the high-pressure energy storage box cover, has controllable glue quantity, is simple and convenient to operate, has high repeatability and is high in practicability. In order to achieve the purpose, the gluing tool for the hot riveting column of the energy storage box body comprises a rubber head tool and a limit ring, wherein the limit ring is arranged at the bottom of the hot riveting column or a bolt, the rubber head tool is arranged at the top end of the hot riveting column or the bolt and positioned, the rubber head tool comprises a positioning hole and a glue outlet hole, the inside of the rubber head tool is provided with the positioning hole connected with the hot riveting column or the bolt, one side of the positioning hole is sequentially provided with a structural glue storage cavity and a main glue inlet hole, and four glue outlet holes are formed in the inner wall of the structural glue storage cavity. Preferably, the diameter of the glue outlet hole is 1.5mm. Preferably, the rubber head tooling is photosensitive resin rubber head tooling. The sectional type glue head tool (photosensitive resin 3D printing) has the bene
