Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor device defect detection devices, in particular to a defect detection tool for semiconductor cavity components. Background Art

[0002] A semiconductor cavity is a micro optical cavity that uses semiconductor materials as its constituent elements. It retains light in a small space through multiple reflections and diffractions, thereby forming a resonant cavity, enhancing the propagation speed and energy of light in it, and improving the power and efficiency of the laser. Therefore, the components inside the semiconductor cavity need to be inspected for defects before assembly after processing.

[0003] For example, a semiconductor device defect visual detection device disclosed in Chinese patent publication number CN218726694U drives a bidirectional screw to rotate through a first reduction motor, thereby driving two screw sleeves threadedly connected to the bidirectional screw and a clamping plate connected to the screw sleeve to move toward each other, thereby fixing the detection device and ensuring the detection effect of the semiconductor device; the second reduction motor drives the active bevel gear and the driven bevel gear to rotate, realizes the rotation of the rotating shaft and the fixed frame, drives the clamping plate and the device to automatically turn over, and realizes the detection of the front and back sides of the device. Compared with the traditional manual turning, it reduces labor intensity and improves the detection rate.

[0004] The following technical issues exist:

[0005] The above-mentioned device enables the device to automatically flip over through a transmission linkage structure. During this process, the power source is mainly provided by the motor, so its flipping force is difficult to control. Flipping too quickly can easily lead to loose connections between components inside the device, causing functional failure of the component after assembly, affecting efficiency. In addition, the stability of the original fixing mechanism must be ensured during the flipping process. Improper maintenance during long-term use can easily cause the cavity component to flip and detach, resulting in the cavity component falling or colliding, which has adverse effects on the integrity of the cavity component and even the safety of the inspection and processing.

During the above rotation process, the insertion block drives the detection assembly set thereon to perform multi-angle detection, and the setting of multiple groups of detection assemblies can ensure the comprehensiveness of the cavity assembly detection.

The connecting shaft body is fixedly installed in the arc-shaped connecting block, the articulated rod is rotatably installed on the connecting shaft body, the other end of the articulated rod is fixedly connected to the crankshaft, and the other end of the crankshaft is connected to the interlocking sleeve.
