A glue coating method with symmetrically arranged double glue heads

Abstract

The invention discloses a gluing method with symmetrically arranged double gluing heads. It has become an urgent need to design a gluing method and device that can improve gluing efficiency, gluing effect, simple and precise control, and meet process requirements. The horizontal device of the present invention drives the longitudinal base of the longitudinal device to move along the direction of gluing, and the longitudinal servo motor drives the two gluing units respectively placed on the upper and lower belt sections of the synchronous belt to move symmetrically towards or against each other. The cylinder drives the glue applicator to move in the direction of the plumb weight, realizing the three-dimensional movement of the two glue applicators. The invention utilizes the symmetrical opposite or opposite movement characteristics of two gluing units placed on the upper and lower belt sections of the synchronous belt, and can most effectively realize the frame sorting and gluing work of "long, short, short, long" due to process requirements, Moreover, the power source is less, the cost is lower, the control method is simple, and the precision is high. It is convenient to disassemble and maintain when a certain gluing unit fails, while the other gluing unit can still perform gluing operations.

Description

technical field [0001] The invention belongs to the field of photovoltaic module preparation machinery, and in particular relates to a glue coating method and device with symmetrically arranged double nozzles. Background technique [0002] As a renewable energy source, solar energy has the advantages of cleanliness, safety, universality, sufficiency, and economy, and plays an important role in long-term energy strategies. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. According to statistics from the National Energy Administration, in 2019, the country's photovoltaic power generation capacity reached 224.3 billion kWh, a year-on-year increase of 26.3%. The huge power generation is due to the huge installed capacity of photovoltaic power generation equipment, which has reached 223 million kilowatts. At the same time, the installed capacity of photovolta...

Problems solved by technology

[0005] The current gluing methods mainly include the following methods: Method 1, equipped with XY coordinate dual servo motor control, using a single gluing head to complete the gluing work of the four frames; this gluing method is inefficient and takes a long time to complete the four frames

Method 2, equipped with double X and single Y coordinate servo motor control, using double gluing heads to complete the four frame gluing work; this method uses double X-axis in method 1, and the distance between the two X-axes is fixed. For "long and short" , short, long" frame arrangement process requirements, when one gluing head glues the long frame, the other gluing head corresponds to the short frame, and the total gluing time is the time for coating two long frames; The time still needs to be improved, and at the same time, the equipment cost of this method is high and the control is complicated
