A processing method of a profile laser device according to any one of claims 1-8, characterized in that: the processing method comprises the following processing steps: Large-size profile positioning: place the large-size profile on the top wall of the machine body (1) so that the profile is against the interference part (4), and the suction part (71) sucks the interference part (4) through the suction pipe (72) air, so that the contact part (4) and the profile form a negative pressure space, thereby improving the positional stability of the large-size profile on the body (1); Positioning of small-sized profiles: Lift the supporting part (5) through the driving part (6), so that the interference part (4) set on the supporting part (5) passes through the preset channel (11) to move to the body (1) above; place the small-sized profile between two adjacent conflicting parts (4); the suction part (71) sucks the air at the conflicting part (4) through the suction pipe (72), so that the profile is tight against the Between two conflicting parts (4); Profile processing: the cutting mechanism (2) is displaced on the machine body (1) to cut large-size profiles or small-size profiles.
