[0028] Beneficial effects of the present invention:

[0029] 1. Put the aluminum plate on the rotating platform, detect the size of the aluminum plate with a visual detector, and control the rotation of the aluminum plate in conjunction with the rotating platform until the four sides are aligned. Then the conveying device clamps the aluminum plate and moves it to the cutting device. After being cut by the cutting device, it is sent out by the direction-dividing mechanism. The four sides of the aluminum plate can be effectively sheared at one time, and then sent out through the direction-dividing mechanism, which effectively reduces manpower and significantly improves production efficiency.

[0030] 3. The directional moving device for the workpiece to be lifted first drives the directional mounting frame to move above the aluminum plate, then descends along the Z axis, the directional suction cup absorbs the aluminum plate, the directional mounting frame moves upward along the Z axis, and the directional rotating device drives the absorbed aluminum plate to rotate, and then the aluminum plate is transported by the directional moving device, which is beneficial to increase the turning speed, improve the processing efficiency of the production line, and avoid safety accidents.

[0031] 4. Drive the split cylinder to drive the split connection block to rotate around the split connection shaft through its output end, and at the same time force the mounting end of the split cylinder to rotate, effectively ensuring the normal rotation of the split connection shaft, thereby driving the split suction cup to rotate; wherein a bearing (not marked in the figure) is connected to the split connection shaft to improve the rotation stability of the split connection shaft; since the size of the split connection block and the distance between the mounting end of the split cylinder and the split connection shaft are fixed, the maximum retractable distance of the split cylinder can be changed according to actual processing needs, thereby changing the swing amplitude of the split connection block around the split connection shaft, thereby changing the rotation angle of the split suction cup.

[0032] 5. The horizontal position of the rotating frame can be arbitrarily changed by combining the first linear motion mechanism and the second linear motion mechanism, which has strong applicability and is convenient for realizing horizontal movement.

[0033] 6. Driving the third servo motor to drive the placement table to rotate is conducive to adjusting the placement of the aluminum plate on the placement table according to actual processing needs. Combining the first linear motion mechanism and the second linear motion mechanism, the rotation accuracy is high and the applicability is strong, which is convenient for horizontal movement and meets any horizontal placement angle.

[0034] 7. As there are rotating exhaust pipes and rotating exhaust holes, the rotating exhaust pipes are connected to a vacuum exhaust device. After the aluminum plate is placed on the placement table, the aluminum plate covers the rotating exhaust holes, the vacuum exhaust device is turned on, and the air at the bottom of the aluminum plate is extracted through the rotating exhaust holes and the rotating exhaust pipe to form a negative pressure, thereby sucking the aluminum plate. The first linear motion mechanism and the second linear motion mechanism are combined to drive the rotating frame to move along the X-axis and the Y-axis to adjust the position of the aluminum plate. The placement table rotates under the drive of the third servo motor to process the aluminum plate. The placement table returns to the origin, the vacuum exhaust device is closed, and the negative pressure at the bottom of the aluminum plate is released, which is convenient for subsequent processing.

[0035] 8. The two clamp limiters are driven to move synchronously along the X and Y axes by the clamp moving parts to fix the position of the aluminum plate, and then return along the X and Y axes, which is beneficial to ensure the clamping stability of the aluminum plate, achieve good processing effect, improve the processing quality of the aluminum plate, and reduce processing costs.

[0036] 9. Slide the clamp limiter along the first guide rail of the clamp, adjust it in the X-axis direction, align it with the position of the aluminum plate, and then use the clamp driver to drive the clamp limiter on the second guide rail of the clamp to move along the Y-axis to effectively fix the aluminum plate.

The active telescopic component 4061 is a split cylinder, the output end of the split cylinder is hinged to the other end of the split connection block 4062, and the mounting end of the split cylinder is hinged to the split rotation frame 405.

[0054] The split cylinder is driven to drive the split connection block 4062 to rotate around the split connection shaft through its output end, and at the same time, the mounting end of the split cylinder is forced to rotate, effectively ensuring the normal rotation of the split connection shaft, thereby driving the split suction cup 404 to rotate; wherein a bearing (not marked in the figure) is connected to the split connection shaft to improve the rotation stability of the split connection shaft; since the size of the split connection block 4062 and the distance between the mounting end of the split cylinder and the split connection shaft are fixed, the maximum retractable distance of the split cylinder can be changed according to actual processing needs, so that the swing amplitude of the split connection block 4062 around the split connection shaft can be changed, thereby changing the rotation angle of the split suction cup 404, and the split cylinder returns to its position, and the split suction cup 404 returns to the origin to wait for the next arrival instruction.

One of the clamp limit members 501 is slidably connected to one of the clamp first guide rails 5021. The clamp second guide rail 5022 is slidably connected to another clamp first guide rail 5021. The clamp second guide rail 5022 extends along the Y-axis. Another clamp limit member 501 is slidably connected to the clamp second guide rail 5022. The clamp driving part 5023 is arranged on the clamp second guide rail 5022 and drives the clamp limit member 501 to move along the Y-axis.

[0077] The clamp limiter 501 is slid along the first guide rail 5021 of the clamp, adjusted in the X-axis direction to align with the position of the aluminum plate, and then the clamp limiter 501 located on the second guide rail 5022 of the clamp is driven by the clamp driving member 5023 to move along the Y-axis to effectively fix the aluminum plate.

[0078] The fixture driving member 5023 includes a fixture driving seat 50231 and a fixture driving electric cylinder 50232. The fixture limiting member 501 is fixedly connected to the fixture driving seat 50231. The electric cylinder is fixedly connected to the bottom of the fixture driving seat 50231. The output end of the fixture driving electric cylinder 50232 is connected to the fixture second guide rail 5022. The fixture driving electric cylinder 50232 drives the fixture limiting member 501 to move along the Y axis.

[0079] The first clamp rail 5021 is provided with a clamp rail electric cylinder 506, one of which is fixedly connected to the clamp stopper 501, and the other is fixedly connected to the second clamp rail 5022.
