Driving method of ejector pin rod and negative pressure jacking type photovoltaic module laminating machine

Abstract

The invention provides a driving method of an ejector pin rod and a negative pressure jacking type photovoltaic module laminating machine to overcome the defects that when an air cylinder is adopted to drive the ejector pin rod in the prior art, the consistency of the ejection speed and time of the ejector pin rod is poor, battery assemblies are prone to being damaged and deviated, the ejection distance of the ejector pin rod is not prone to being detected, and defective products are prone to being generated. The laminating machine comprises a heating plate and an ejector pin system, the ejector pin system comprises a plurality of ejector pin rods and an ejector pin rod driving mechanism, a through hole for the ejector pin rods to pass through is formed in the heating plate, and the method comprises the steps that a telescopic pipe stretches out and draws back in the axial direction of the telescopic pipe by inflating and exhausting air in the telescopic pipe so as to drive the ejector pin rods fixedly connected with the telescopic pipe to reciprocate to drive the ejector pin rods to rise and fall. According to the driving method of the ejector pin rod and the negative pressure jacking type photovoltaic module laminating machine, additional debugging operation is not needed, manpower and material resources are saved, installation and debugging are easy, the debugging time is shortened, the production efficiency is improved, the problem of positioning failure is avoided, and the action is simple, reliable and easy to control.

Description

technical field [0001] The invention relates to the technical field of solar lamination equipment, in particular to a laminator and a driving method for a thimble rod thereof. Background technique [0002] The laminator is a lamination device for solar cell components. The cell components are laminated in the vacuum chamber of the laminator, and the cell components are transferred to the vacuum chamber of the laminator by the transmission device. Lift up from the heating plate for processing. After the processing is completed, the thimble rod will fall back, and then the battery assembly will be transported to the vacuum chamber by the transmission device for the next process. The thimble bar is driven up and down by the driving device. At present, in the laminating machine market, the common driving device of the thimble rod is the cylinder drive, and the magnetic switch is used for position feedback to control the stroke of the cylinder, thereby controlling the stroke of ...
