Description

Technical Field

[0001] The utility model relates to the technical field of junction box assembly, in particular to a disassembly tool for a backplane junction box of a photovoltaic module. Background Art

[0002] In the field of new energy power generation, solar photovoltaic power generation occupies an important position. Solar photovoltaic power stations can directly convert light energy into electrical energy, and have the advantages of no pollution, long service life, and no need for maintenance. In recent years, the development of photovoltaic power generation projects has been very rapid. In the existing photovoltaic module system, the connection between each photovoltaic module is generally realized through a junction box and its connecting wire. The junction box is adhered to the backplane of the photovoltaic module by using glue. In different stages such as the production and manufacturing, engineering installation, and power station operation of the photovoltaic module, diode failures and damages in the junction box may occur due to different factors such as quality, environment, and construction, thus causing each module to be unable to generate electricity normally.

[0003] For example, the patent with the publication number CN202223051636.8 discloses "A Disassembly Tool for a Junction Box". By setting baffle components on both sides of the tool bit, the tool bit can be shielded and limited, so that the tool bit always accurately faces the glue between the module and the backplane, avoiding possible damage to the backplane of the module or the battery chip during manual operation, and improving the service life of each photovoltaic module.

[0004] Although the above-mentioned tool bit is shielded and limited by the baffle components, when replacing the backplane junction box, it is necessary to use a knife to separate the glue of the backplane junction box of the photovoltaic module. When the force is too strong, there is a risk of damaging the photovoltaic module, which is not conducive to the convenience of disassembling the photovoltaic module. Summary of the Utility Model
