Description

[0002] With the rapid development of lightweight photovoltaic modules, more and more photovoltaic modules are installed directly and quickly on the base surface by gluing. Specifically, when implementing the gluing, the construction workers need to apply the adhesive in strips on the base surface or the back of the photovoltaic module through the glue injection head of the glue injection gun, which not only has low construction efficiency, but also leads to poor uniformity of each adhesive strip, and even causes individual adjacent adhesive strips to adhere to each other, resulting in poor quality of glue injection construction.

[0003] The utility model patent with authorization announcement number CN 211587320U discloses a glue dispensing head with multiple glue outlets 3. However, since all glue outlets 3 are connected to the glue connecting part 2 through a single guide channel 4, it is found in actual construction that the glue discharge uniformity of each glue outlet 3 is poor, some glue outlets 3 discharge too much glue, and some glue outlets 3 discharge too little glue, and the quality of glue injection construction is still poor.
