LV13253B - Device and method for coating roll substrates in vacuum - Google Patents

Abstract

The invention relates to coating roll substrates in vacuum, particularly to the deposition process, which are associated with depositing significant amounts of metals or other materials, causing significant thermal loads on the substrate. Nonmetallic roll materials, polymeric films or thin metal foils can be used as substrate. According to the invention the roll vacuum coating device shown on fig.1 and fig.2, consists of vacuum chamber (1), source of deposited material (2), installed inside the chamber, and rotatable drum (3) with cylindrical pressure rollers (4). Source of deposited material (2) and rotatable drum (3) compose zone (5) inside the vacuum chamber (1) of coating the substrate (6). The device is equipped with the means of the substrate-hold down and transverse spreading as the elastic laces (7) of the specials asymmetrical profile, guide rollers and pressure rollers (9). Shell of drum (3) is equipped with system of holes (10), which are connected with the pipeline (11) of gas introduction. Gas from a relevant source (not shown) is introduced through the said pipeline, gas manifold (12) and holes (10) into gap (13) between the surface of drum (3) and substrate (6). The drum is also provided with pipeline (14) of the liquid coolant introduction into its inside space and with pipeline (15) of the liquid coolant withdrawal. The section of holes (10), which is not covered by substrate (6), can be separated by locks (16) from deposition zone (5) for additional decrease of the load onto the vacuum pumping means. A method offered for coating roll substrates in vacuum is characterized by the step of depositing the coating on the central zone of the substrate width, leaving the substrate edges free from the coating, and by the step of holding down the said free edges of the substrate to the supporting surface of the rotatable drum in the deposition zone in such a manner, that the component of the frictional force of the substrate against the supporting surface provides the force of the substrate transverse spreading to both sides in addition to the lengthwise tension.

Claims (12)

A device for applying a coating in a vacuum on a rolled material (substrate) comprising: a rotating drum, the surface of which serves as a base for the substrate, and comprising channels with outlet openings in said base surface; a gas source and a gas collector connected to said channels; coating application means in the immediate vicinity of the drum; characterized in that, in order to expand the technological capabilities of the device and increase the process productivity at the expense of heat exchange intensification between the base and the base, the device comprises means for forcing the side edges of the base onto the drum and the base for transverse stretching. Device according to claim 1, characterized in that the means for forcing the side edges of the base onto the drum and the base for transverse stretching are provided in the form of a elastic twine with a special asymmetrical profile, a guide roller and a press roller for ripping the cords together with the drum, the press rolls being arranged such that the gap between the rollers and the base at the beginning of the contact between the twine and the base is equal to the height of the twine profile, while at the end of the twine and the base the said gap is less than the height of the twine profile. Device according to claim 1, characterized in that the means for pressing the side edges of the base and transverse stretching of the substrate are provided in the form of elastic cords and guide rollers for the twine to be twisted together with the twisting plane at an angle to the direction of movement of the base; but the apex of that angle is directed against the movable base. Device according to claim 3, characterized in that the angle between the twisting plane of the twine and the direction of movement of the base is from 10 to 20 degrees. Device according to claim 1, characterized in that the means for forcing the lateral edges of the base and transverse stretching of the base is formed as a set of press rollers mounted at an angle to the rotational plane of the drum, said apex being directed against the movable base. Device according to claim 5, characterized in that the angle of installation of the compression roller against the rotational plane of the drum is from 10 to 20 degrees. Device according to claim 5 or 6, characterized in that the press rollers are formed in the form of pairs of wheels, each pair of wheels being pressed against the surface of the drum in such a way that each pair of wheels is in direct contact with the drum bearing surface, but this pair's second wheel is in contact with the drum surface through the bottom of the roller-mounted base. Device according to claim 1, characterized in that the means for transverse stretching of the substrate is formed in the form of a disc mounted on the ball head at the ends of the drum coaxially with a drum, and in the form of a support which is placed on the outside of each disc, with the diameters of the discs being equal to drum diameter and springs mounted on the perimeter of the disc. A method for applying a coating in a vacuum on a roller-bearing substrate comprising: forming a deposition area and equipping said area with a rotating drum having a footprint for said base and channels with outlets on the base surface; transporting the rolled substrate through the coating deposition area; providing gas through said channels in the gap between the base and the base, characterized in that, in order to increase process productivity at the expense of heat exchange between the substrate and the base, the coating is deposited in the central zone of the substrate along its width, leaving the edges of the substrate free of coating, in addition, the free edges of said base in the coating deposition area are pressed into the rotating drum in such a way that the friction force component between the base and the support surface in addition to the longitudinal tension provides transverse stretching of the substrate on both sides. 10. A method according to claim 9, wherein the base area on which the coating is applied is at least 80% of the base width. 11. A method according to claim 7, characterized in that the total tensile strength of the base in the transverse direction is at least 10% of the longitudinal stretching force. Method according to claim 8, characterized in that the gas pressure in the gap between the base and the base is between 10 and 500 Pa.
