9. The method of using a laser processing assembly tool for an instrument panel passenger side air bag zone of an automobile as described in claim 6, wherein, When producing the air bag frame laser cutting, the following steps are included: Step 1: loosen the locking mechanism handle (10-2) of the air bag frame locking mechanism (10) to pull the locking mechanism lock rod (10-1) outward, so that the upper locking hook (10-1-1) of the locking mechanism lock rod (10-1) is away from the air bag frame upper clamping limiting round block (16-1), thereby loosening the air bag frame locking mechanism (10), and the air bag frame upper clamping pad (3-1) and the air bag frame lower clamping pad (3-2) open the air bag frame clamping tool upper panel (4) of the air bag frame cutting tool (1) upward under the action of the flip hinge (6); during this process, the lower locking hook (10-1-2) contacts the air bag frame lower clamping limiting round block (16-2) to limit the opening angle of the locking mechanism lock rod (10-1), Step 2: the operator moves the air bag frame cutting tool (1) through the air bag frame clamping tool longitudinal handle (5) and the air bag frame clamping tool oblique handle (12), and places the air bag frame to be processed into the air bag frame cutting tool (1), and completely positions the air bag frame to be processed in the air bag frame cutting tool (1) through the clamping tool first limiting column (7), the clamping tool second limiting column (8), the air bag frame installation positioning block (14), the air bag frame supporting block (15), and the third air bag frame tool combined limiting block (9-6) and the fourth air bag frame tool combined limiting block (9-7), and closes the air bag frame clamping tool upper panel (4) downward under the action of the flip hinge (6), and completes the closing limiting through the air bag frame upper clamping limiting round block (16-1) and the air bag frame lower clamping limiting round block (16-2) contacting each other, and locks the air bag frame clamping tool upper panel (4) through the air bag frame locking mechanism (10), and at the same time, the pressing bolt (13-1) and the air bag frame pressing spring (13-2) installed on the air bag frame clamping tool upper panel (4) press the air bag frame cutting tool (1) together with the air bag frame to be processed as a whole, which also plays a role in correcting the deformation of the air bag frame during the pressing process; Step 3: The airbag frame cutting tool (1) is placed on the instrument panel skeleton laser weakening tool (2) together with the airbag frame to be processed. The basic positioning of the airbag frame cutting tool (1) is completed through the first cutting tool auxiliary limiting column (41-1), the second cutting tool auxiliary limiting column (42-1), the third cutting tool auxiliary limiting column (41-2) and the fourth cutting tool auxiliary limiting column (42-2). The horizontal limiting is completed by inserting and positioning the first airbag frame tool combined positioning hole (9-3) and the first airbag frame cutting tool combined positioning column (35) of the airbag frame cutting tool (1), and by inserting and positioning the second airbag frame tool combined positioning hole (9-5) and the second airbag frame cutting tool combined positioning column (32). The vertical support is achieved by the first airbag frame tool combined limiting block (9-2) and the second airbag frame tool combined limiting block (9-4) of the airbag frame cutting tool (1) contacting the first bottom plate tool combined positioning block (39-2) and the third bottom plate tool combined positioning block (39-4). In addition, the second bottom plate tool combined positioning block (39-3) and the fourth bottom plate tool combined positioning block (39-5) contact the third airbag frame tool combined limiting block (9-6) and the fourth airbag frame tool combined limiting block (9-7) below the airbag frame cutting tool (1), also achieving vertical support. The airbag frame cutting tool (1) is completely positioned and fixed on the skeleton laser weakening tool (2), and the cutting tool detection sensor (33) recognizes that the airbag frame cutting tool (1) is placed on the tool. The program used is the airbag frame laser cutting program. Step 4: Start the laser cutting program.
