Description

Technical Field

[0001] The present application relates to the technical field of workpiece sorting, and in particular to a detection and automatic sorting device for plastic workpieces. Background Art

[0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise size. Injection molding is a processing method used in mass production of certain complex-shaped workpieces.

[0003] Plastic workpieces produced by injection molding usually need to be manually unloaded and transported after production. During the unloading or transportation process, it is inevitable that structures will be missing or damaged. Therefore, workers are required to inspect the workpieces before use and distinguish between qualified and unqualified products to prevent unqualified products from affecting the quality of subsequent use.

[0004] However, when manual inspection is used, when there are many workpieces to be inspected, especially when the structure of the workpiece to be inspected is small, since it is necessary to inspect and judge the local structure on the workpiece, the method of judging only by the naked eye of workers is not only time-consuming and labor-intensive, but also has low inspection efficiency and it is difficult to ensure that there are no errors in the inspection, which is not conducive to practical use.

The second blowing assembly 5 is arranged on the side of the turntable 22 away from the detection assembly 3, and a sensor is arranged at the second blowing assembly 5. The induction switch 20 is fixed on the frame 1 and is electrically connected to the PLC device. When in use, the qualified workpiece is moved away from the detection component 3 under the rotation of the turntable 22. When it rotates to the second blowing nozzle 52, the induction switch 20 detects that the workpiece transmits an electrical signal to the PLC device. The PLC device receives and processes the electrical signal, thereby controlling the air pump to ventilate the second ventilation pipe 53, and then blows the workpiece away from the turntable 22 through the second blowing nozzle 52, so that the qualified workpiece is finally unloaded through the second unloading component 7.

When the workpiece rotates to the bottom of the industrial camera 32, the industrial camera 32 transmits a signal to the PLC device, the PLC device receives and processes the signal, and controls the rotating shaft of the motor 23 to stop rotating. After that, the industrial camera 32 detects and determines whether the workpiece is qualified. If the workpiece is unqualified, the industrial camera 32 transmits a signal to the PLC device again, the PLC device receives and processes the signal, and controls the air pump to ventilate the first ventilation pipe 43, and blows air through the first blowing nozzle 42, thereby blowing the unqualified workpiece into the first The discharge port 61 slides into the first storage box 9 along the first discharge guide rail 62; if the workpiece is qualified, the industrial camera 32 transmits a signal to the PLC device, the PLC device receives and processes the signal, and at the same time controls the shaft of the motor 23 to restart, driving the turntable 22 to rotate to transport the workpiece.
