Description

Solar panel aluminum profile frame processing drilling machine

Technical Field

The utility model relates to the technical field of solar panel production, in particular to a drilling machine for processing aluminum profile frames of solar panels.

Background Art

Solar cells are a type of photoelectric semiconductor sheet that uses sunlight to generate electricity directly. Single solar cells cannot be used directly as a power source. To be used as a power source, several single solar cells must be connected in series and parallel and tightly sealed into components. Solar panels are assembled with multiple solar cells and are the core part of the solar power generation system. When manufacturing the above-mentioned aluminum frame, solar panel manufacturers need to use a drilling machine to open reserved holes at the four corners of the solar panel aluminum frame for subsequent on-site positioning and assembly.

The Chinese patent application number CN202321102715.9 discloses a drilling machine for processing the aluminum profile frame of a solar panel. It includes a base, a movable platform is provided on the top of the base, and the movable platform is used to place the aluminum profile, and also includes: a fixing assembly, the fixing assembly includes a lower fixing seat, a first slide plate and a second slide plate, and the first slide plate and the second slide plate can both move toward the inner side wall of the lower fixing seat.

The above scheme still has limitations in actual use. In the above scheme, when drilling holes in the aluminum frame, the debris generated by the drilling will remain on the surface of the processing table. When the subsequent aluminum frame is drilled, the debris will cause the aluminum frame to be unable to be placed flat, which affects the accuracy of the hole. Secondly, after the hole is drilled, a large amount of debris is adsorbed on the surface of the drill bit. If it is not cleaned in time, the service life of the drill bit will be reduced. In addition, the drill bit containing debris will affect the accuracy of the hole when used, and cause the surface of the aluminum frame hole to contain a large amount of burrs. To this end, we provide a solar panel aluminum profile frame processing drilling machine to solve the above problems.
