Technical Field
[0001] The utility model relates to the technical field of printer component production, and in particular to an automatic screw tightening device for a printer feeder cover. Background Art
[0002] The printer's paper feeder is one of the core components of a printer. Its main function is to extract paper from the paper box or tray and feed it into the printer for printing. The printer's paper feeder cover, as an integral part of the printer, is usually located at the bottom or side of the printer. Its main function is to cover and protect the paper feeder.
[0003] During the production and assembly process of the printer feeder cover, the cover needs to be precisely assembled with the printer body. This process usually involves placing the printer feeder cover on a movable table, then starting the mobile device and moving the screw tightening device to the cover position for screw assembly. However, the existing placement platform design is relatively simple, mainly using a matching concave surface to form a recessed inlay to provide a platform for the placement of the printer feeder cover. However, this method has poor adaptability for different models of printer feeder covers. Because different printer feeder covers have different external dimensions, the placement support mold platform needs to be frequently replaced, which not only brings inconvenience to the operation, but also affects the assembly efficiency.
