Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel production equipment, in particular to a device for automatically placing a junction box cover by a mechanical arm. Background Art

[0002] The junction box cover on the photovoltaic panel mainly plays the following important roles: 1. Protecting internal components: The junction box contains electronic components such as wire connection terminals and bypass diodes. The cover can effectively prevent moisture, dust and other external contaminants from entering, protecting these sensitive components from environmental damage, thereby extending the service life of the junction box and the entire photovoltaic module. 2. Safety protection: The circuit connection in the photovoltaic junction box is directly related to the safety of power transmission. The cover can prevent accidental electric shock and protect the safety of operators and maintenance personnel. 3. Waterproof and fireproof: Especially for photovoltaic modules used outdoors, the junction box cover usually adopts a waterproof and fireproof design, which can keep the interior dry under severe weather conditions and prevent short circuits or fire risks. 4.
