Description

Technical Field

[0001] The utility model relates to the technical field of aluminum die-casting inspection, in particular to an automobile aluminum die-casting inspection device. Background Art

[0002] When aluminum die castings are produced, defects are prone to occur on their surfaces, such as sunken areas, bubbles, cracks, deformations, cold shuts and mesh hair wings on the smooth surface of the castings. The main reasons for these defects are that the metal liquid is too low in the injection chamber, which easily generates air entrapment, the initial injection speed is too high; the mold pouring system is unreasonable and the exhaust is poor; the melting temperature is too high, the gas content is high, and the melt is not degassed, etc.

[0003] According to the authorization announcement number CN219266132U, a surface defect detection device for vehicle aluminum die-castings is provided. By connecting an external power supply, the die-casting body is placed above the conveyor belt transmission component, and the front of the die-casting body can be detected by the first detection camera. The conveyor belt transmission component is driven by starting the second motor to transport it to the drive roller and inserted into the groove. The die-casting body squeezes the pressure sensor in the groove, so that the pressure sensor starts the suction device and the first motor. The suction device sucks the die-casting body into the suction disk through the through hole at the suction disk, and then the first motor drives the installation shaft to rotate, so that the installation shaft drives the transmission roller to rotate, and the transmission roller drives the die-casting body to flip to the horizontal and vertical position of the second connecting plate, and the die-casting body can be detected by the second detection camera. After the detection is completed, the first motor drives the die-casting body to flip to the conveyor belt transmission component on the other side, and another first detection camera above the conveyor belt transmission component can clearly detect the back of the die-casting body. The structure is simple to operate and easy to use.

[0004] Aluminum die-castings can be conveyed and inspected through the above-mentioned conveyor belt transmission assembly and other structures. However, in the process of conveying the aluminum die-castings by the conveyor belt transmission assembly, the aluminum die-castings are easily displaced on the conveyor belt transmission assembly and misaligned with the inspection camera, thereby affecting the inspection results of the aluminum die-castings.
