Independent rotary nozzle type compact gluing head capable of being detected online and gluing method thereof

Abstract

The invention discloses an independent rotary nozzle type compact gluing head capable of being detected online and a gluing method thereof. An existing frame gluing machine realizes change of a nozzle angle by rotating a gluing valve integrally, and is complex in structure and large in power consumption. The gluing head comprises a glue supply assembly of the gluing valve, a nozzle rotating mechanism and an online bilateral detection device, wherein a rotating air cylinder of the nozzle rotating mechanism drives a flat needle nozzle to rotate and the flat needle nozzle rotates directly to glue photovoltaic frames arranged inside and outside with different orientations by a single gluing head, such that the power consumption is reduced. The online bilateral detection detects whether the flat needle nozzle is aligned with a gluing groove of a to-be-glued frame or not online and whether the height of the gluing groove meets a gluing demand or not, the glue surface height after gluing changes, such that it is ensured that the system finds the quality problem of the gluing groove in time to replace the gluing frame as well as finds and corrects a gluing error caused by deviation of the gesture of the flat needle nozzle, unsmooth glue discharge or too quick glue discharge, thereby improving the gluing quality to the maximum extent.

Description

technical field [0001] The invention belongs to the field of photovoltaic module preparation mechanical equipment, and in particular relates to an independent rotating nozzle type compact gluing head capable of on-line detection and a gluing method thereof. Background technique [0002] Photovoltaic energy converts solar radiation energy into electrical energy based on the principle of photovoltaic effect. It has the advantages of no pollution, no noise, low maintenance cost, and long service life. It is considered to be the most important new energy in the 21st century. A single solar cell cannot be directly used as a power source. As a power source, a number of battery cells assembled from single solar cells, special tempered glass, packaging materials, functional backplanes, junction boxes, and aluminum alloy frames must be assembled in series. , parallel and tightly packaged into photovoltaic cell modules. The photovoltaic cell module is the core part of the solar power...

Problems solved by technology

Among them, the gluing operation of the gluing system that has the most critical impact on the quality of gluing, when the transfer platform sends the frame arranged in a preset way to the gluing area, the gluing valve is used to rotate as a whole to drive the nozzle fixed to it Although this existing rotary gluing valve method can better meet the gluing requirements of the gluing head on the frames arranged in different directions on the gluing area, its cumbersome and heavy mechanical structure takes up a large working space and Power consumption, and there is no online detection device for a single set of gluing heads, it is difficult to detect and feed back gluing errors caused by needle posture and poor gluing in real time during the gluing process, which affects gluing efficiency and coating efficiency. glue quality
