COLOUR MARKING METAL SURFACES

摘要

Apparatus related to marking a metal surface are provided. The solution comprises receiving (600) control data comprising information on the marking of a pattern on the metal surface; controlling (604, 606) a temperature control unit and a gas unit to produce a temperature and atmosphere in space under a cover on the basis of the control data; controlling (602) the focus and bandwidth of a laser marking unit on the basis of the control data to produce the pattern defined in the control data on the metal surface; and controlling (608) a coating unit on the basis of the control data to produce a coating on the metal surface.

主权项

1. An apparatus for marking a metal surface, comprising:
a bed for an object comprising a metal surface; a cover forming an airtight space over the bed; a laser marking unit capable of forming a laser beam onto the metal surface; a gas unit for controlling the atmosphere of the space under the cover; a coating unit for producing a coating on the metal surface; a temperature control unit for controlling the temperature of the space under the cover; at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: receive from a remote computer control data comprising parameters to create a pattern on the metal surface; control the temperature control unit and the gas unit to produce a temperature and atmosphere in space under the cover on the basis of the parameters; control the focus and bandwidth of the laser marking unit on the basis of the parameters to produce the pattern on the metal surface; and control the coating unit on the basis of the parameters to produce a coating on the metal surface.
