10. A processing technology of an RO membrane filter element is characterized in that: the method comprises the following steps:

s1, feeding of membrane: after the membrane material feeding and cutting device (13) cuts the membrane material roll (114), the membrane is pulled by a first manipulator (15), and the membrane is laid on a first placing table top (111);

s2, feeding through a separation net: after a screen material roll (113) is cut by a screen feeding and cutting device (12), a screen is pulled by a second manipulator (16), the screen is stacked on a membrane of a first placing table top, the cutting length of the screen is half of that of the membrane, the screen is stacked at one end of the membrane, and the membrane is aligned with the end part of the screen;

s3, folding the membrane: the folding device (3) acts on the middle part of the diaphragm, the first mechanical arm (15) drives one end of the diaphragm, which is not stacked with the separation net, to move towards the other end until the two ends of the diaphragm are aligned, at the moment, the middle part of the diaphragm forms a crease under the action of the folding device, and the separation net is clamped in the folded diaphragm to form a filtering unit at first;

s4, transfer: a grabbing component of the third manipulator (17) grabs the primary filtering unit and moves the primary filtering unit to the second placing table board (112);

s5, flow guiding and distributing feeding: the guide cloth feeding and cutting device (14) is lifted under the driving of a third lifting electric cylinder (116), and after the guide cloth roll (115) is cut, the guide cloth is pulled by a grabbing component of a third manipulator (17) and stacked on the primary filtering unit to form a reverse osmosis membrane unit;

s6, feeding and welding a central pipe: the central pipe clamping and rotating device (2) clamps the central pipe, the moving frame (21) drives the central pipe to move above the welding device, the outer layer flow guide cloth feeding device (19) conveys the outer layer flow guide cloth between the welding device and the central pipe, and the welding device welds and fixes the front end of the outer layer flow guide cloth on the outer wall of the central pipe;

s7, winding the outer layer of flow guide cloth: the central tube clamping rotating device (2) drives the outer layer flow guide cloth to wind and wind on the outer wall of the central tube, and the number of winding turns is 3-10;

s8, rolling the film: the reverse osmosis membrane unit is transferred to a supporting platform (118) from a second placing table board (112) by a translational conveying device (7), an obliquely inserted feeding device (4) clamps the overlapped reverse osmosis membrane unit, the reverse osmosis membrane unit is obliquely inserted into an included angle between a central pipe and outer layer flow guide cloth at an inclined angle of 20-50 degrees, so that the reverse osmosis membrane unit is overlapped with the outer layer flow guide cloth, the central pipe clamping rotating device (2) drives the central pipe to rotate, and the reverse osmosis membrane unit is wound into a filter element;

s9, blanking: the central tube clamping and rotating device (2) loosens the clamping of the central tube, and then the material can be discharged.
