Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a high-efficiency airtight hydrogen battery shell sealing device. Background Art

[0002] A hydrogen battery is a device that uses hydrogen as fuel to generate electricity through chemical reactions. It utilizes hydrogen and oxygen to undergo electrochemical reactions under the action of a catalyst to generate water and release energy. Hydrogen batteries have the advantages of high energy density, cleanliness and environmental protection, and are an important development direction in the future energy field.

[0003] After searching, the document of announcement number "CN218385468U" mentioned that "the utility model discloses a cylindrical battery shell sealing mechanism, the sealing mechanism includes a sealing base, a slit for inserting the cylindrical battery shell is provided in the sealing base, and the shape of the slit is adapted to the shape of the cylindrical battery shell; a plurality of first sealing bodies are provided in the slit, and the first sealing bodies are inflatable and deflable annular airbags, and the first sealing bodies are provided on the outside of the cylindrical battery shell; the sealing base is provided with a first air channel for inflating and defleasing air to the first sealing bodies; a gap is provided between the end of the cylindrical battery shell and the bottom of the slit". When in use, the utility model can seal the end of the cylindrical battery shell in the radial direction of the cylindrical battery shell to complete the airtightness test of the cylindrical battery shell. This method can effectively solve the problem of sealing the end of the cylindrical battery shell in the prior art. However, during the sealing process of the hydrogen battery, the safety of the battery is reduced due to the installation of the top cover of the hydrogen battery itself, such as installation misalignment. Most of the current battery installations are installed in an ectopic manner. Even if the glue coating equipment is finished, it is moved to another device to install the top cover. However, this easily causes the top cover and the glue coating position to have a force point misalignment, resulting in the colloid not completely and tightly bonding the top cover to the hydrogen battery shell.

[0004] Therefore, we provide a high-efficiency airtight hydrogen battery shell sealing device to solve the above problems. Utility Model Content

[0011] Preferably, the glue supply head and the extrusion plate are welded, and the glue supply head and the glue supply pump are connected by a pipeline.

[0012] Preferably, a sealing auxiliary component is installed on the inner side of the sealing frame, and the sealing auxiliary component includes an infrared sensor, a control panel, a hydraulic rod and a limit plate.

[0013] Preferably, the limit plate and the hydraulic rod are welded, and the limit plate and the hydraulic rod are symmetrically arranged about the central axis.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the setting of the hydrogen battery shell sealing mechanism, when it is needed, the hydraulic pump rod will push the mounting frame and the extrusion plate downward to complete the injection when injecting glue. Then, after the cover is installed, it will be pushed down again for extrusion, so that the installation position of the cover and the battery shell is perfectly bonded to reduce the gap. The force damping will be squeezed for the second time on the extrusion plate to seal the shell and the cover, thereby avoiding damage to the battery shell due to excessive extrusion force and improving safety. At the same time, due to its own strength, it can also ensure the sealing of the installation. Finally, the glue supply head will first supply glue from the glue supply pump for smearing, and then follow the second descent of the extrusion plate. The glue supply head will squeeze the cover to achieve the bonding effect. Since it is in the same position as the glue, it can ensure the sealing of the colloid to the cover and the hydrogen battery shell.

[0016] 2. Through the setting of the sealing auxiliary component, when it is needed, the infrared sensor will sense the placement of the battery shell in real time. When hydrogen leaks, the infrared sensor will sense the infrared changes of the hydrogen leakage, which will be displayed through the control panel to improve the airtightness detection during the processing.
