An infrared positioning sensor can be embedded on the upper side of the electromagnetic suction plate 8 to align and find the workpiece to be cut. In the process of picking up the workpiece, when the workpiece is stuck in the cutting hole of the steel plate raw material, the first translation mechanism and the second translation mechanism adjust the electromagnetic suction plate 8 to the bottom of the workpiece, start the electric push rod 7 to work and extend, and push the energized electromagnetic suction plate 8 to contact the workpiece for adsorption and fixation. Then, start the electric push rod 7 to work and contract, which can drive the workpiece on the electromagnetic suction plate 8 to move downward and separate from the steel plate raw material. Then, start the swing arm motor 6 to work and drive the electric push rod 7 to swing to tilt the workpiece.

The two connecting rods 15 pass through the two sliding openings 16 respectively and are fixedly connected to the movable strip shell 4. The first motor 9 is started to work, and the first rotating rod 10 is driven to rotate. Since the two driving wheels 11 are transmitted to the two driven wheels 13 through two transmission belts 14, at this time, the two transmission belts 14 are synchronously transmitted, thereby driving the two connecting rods 15 to move synchronously, which can drive the movable strip shell 4 to translate along the X-axis direction, thereby realizing the position adjustment of the electromagnetic suction plate 8, so as to accurately find the workpiece after cutting.

[0023] like Figure 3 As shown, the first rotating rod 10 and the two driving wheels 11, and the second rotating rod 12 and the two driven wheels 13 are fixedly connected by welding, and the connection is firm.

[0024] like Figure 4 As shown: the second translation mechanism includes a second motor 17 fixed at the front end of the moving strip housing 4, the main shaft end of the second motor 17 passes through the moving strip housing 4 and is fixedly connected to a screw rod 18, and a threaded block 19 is threadedly connected to the screw rod 18, and a connecting block 20 is fixedly connected to the upper side of the threaded block 19, and an opening 21 is provided on the upper side of the moving strip housing 4.

[0028] Working principle: When the device is used to pick up the cut workpiece during the laser cutting process, if the workpiece is stuck in the cutting hole of the steel plate raw material, the first motor 9 is started to drive the first rotating rod 10 to rotate. Since the two driving wheels 11 are transmitted to the two driven wheels 13 through the two transmission belts 14, the two transmission belts 14 are synchronously transmitted at this time, thereby driving the two connecting rods 15 to move synchronously, and the movable strip shell 4 can be driven to translate along the X-axis direction. Secondly, the second motor 17 is started to drive the screw rod 18 to rotate. Since the screw rod 18 is threadedly connected to the threaded block 19, the threaded block 19 is forced to translate along the Y-axis direction to realize the electromagnetic suction plate. 8 is adjusted to the position of the workpiece after cutting; then, when the electromagnetic suction plate 8 is adjusted to the position just below the workpiece, the electric push rod 7 is started to extend, and the energized electromagnetic suction plate 8 is pushed to contact the workpiece for adsorption and fixation, and then, the electric push rod 7 is started to retract, which can drive the workpiece on the electromagnetic suction plate 8 to move downward and separate from the steel plate raw material, and then, the swing arm motor 6 is started to drive the electric push rod 7 to swing to tilt the workpiece, and then, the electromagnetic suction plate 8 is powered off to lose its adsorption force on the workpiece. At this time, the workpiece can be automatically unloaded due to gravity. The device can quickly remove the workpiece stuck in the cutting groove of the steel plate raw material, and the material removal is stable and efficient.
