[0023] The suction clamping mechanism 8 also includes a slide plate 802, a bracket 803, and a sliding groove 804. The inner wall of the adapter block 7 is provided with evenly distributed sliding grooves, and the slide plate 802 is slidably connected between the sliding grooves.

[0024] The working principle of this utility model is as follows:
[0025] When handling injection-molded products, the microcontroller 14 controls the operation of motor 9. The output shaft of motor 9 drives the rotating shaft to rotate, which in turn drives the support rod 3 to rotate. Then, motor 2 10 operates, and its output shaft drives the transmission shaft to rotate, which in turn drives the support rod 4 to rotate. Next, motor 3 11 operates, and its output shaft drives the rotating column to rotate, which in turn drives the support bar 5 to rotate. Then, motor 4 12 operates, and its output shaft drives the rotating column to rotate, which in turn drives the connecting rod 6 to rotate. Finally, motor 5 13 operates, and its output shaft drives the rotating column to rotate, which in turn drives the adapter block 7 to rotate, which in turn moves the suction clamping mechanism 8 to the top of the injection-molded product.
[0026] Next, an external hydraulic pump pressurizes the hydraulic rod 801, causing it to operate. The telescopic end of the hydraulic rod 801 pushes the slide plate 802 downward between the sliding grooves. Simultaneously, as the support 803 moves downward, its lower end slides and rotates inside the slide groove 804, causing the middle part of the gripper 806 to open under the rotation within the slot 805. As the gripper 806 opens, the slide plate 802, through the support column 807 and the vacuum generator 808, drives the suction cup 810 to make close contact with the injection-molded product. Then, the vacuum generator 808 and the solenoid valve 809 operate. (An external air compressor is connected to the vacuum generator 808 via an air pipe.) When the external air compressor is running, the solenoid valve 809 opens, and compressed air enters from the air pipe of the vacuum generator 808. It passes through a Laval nozzle, which accelerates the air as it passes through. The increased fluid velocity leads to a decrease in pressure. At the nozzle outlet, the high-speed flowing air forms a low-pressure area. The air around the suction cup 810 is drawn into this area through the connecting pipe at the vacuum inlet. The drawn-in air mixes with the high-speed flowing compressed air in the mixing chamber and then is discharged together from the exhaust port of the vacuum generator 808.
[0027] As compressed air is continuously supplied, a negative pressure is continuously generated, connecting the suction cup 810 to the vacuum generator 808 via a connecting pipe. When the suction cup 810 comes into contact with the injection molded product, a relatively sealed space is formed between them. Due to the pressure difference, an adsorption force is generated, causing the suction cup 810 to lift the injection molded product. Then, the external hydraulic pump depressurizes the hydraulic rod 801, and the telescopic end of the hydraulic rod 801 pulls the slide plate 802 upward, which in turn drives the slide plate 802 upward. The slide plate 802, through the bracket 803 and the slide groove 804, causes the middle part of the gripper 806 to close under the rotation inside the strip hole 805 to clamp the injection molded product. After the injection molded product is moved to the desired position, the external hydraulic pump pressurizes the hydraulic rod 801, and the gripper 806 is released. Then, the external air compressor and vacuum generator 808 are turned off, the suction cup 810 returns to normal pressure, and the suction cup 810 releases the injection molded product.
[0028] It is worth noting that the vacuum generator 808, solenoid valve 809, motor 1 9, motor 2 10, motor 3 11, motor 4 12 and motor 5 13 disclosed in the above embodiments are as follows: vacuum generator 808 can be CV-15HS, solenoid valve 809 can be 2V025-08, motor 1 9, motor 2 10, motor 3 11 and motor 4 12 can all be KS-370, motor 5 13 can be 35BYJ46, and the single-chip microcomputer 14 controls the operation of vacuum generator 808, solenoid valve 809, motor 1 9, motor 2 10, motor 3 11, motor 4 12 and motor 5 13 using methods commonly used in the prior art.
