Abstract
Description
Technical Field
[0001] The present application relates to the technical field of code reading equipment, and more specifically, to a code reading equipment with a detection function. Background Art
[0002] The main processing methods for wafers are piece processing and batch processing, which means processing one or more wafers at the same time. As the feature size of semiconductors becomes smaller and smaller, the processing method tends to be more direct component identification, and product identification is done on the product itself. Wafer manufacturers spray product character information on the wafer body, which saves space and is not easy to damage.
[0003] The document CN 220933500U provides a code reading device with a detection function. A calibration instrument is set up to judge whether a wafer is placed stably and not tilted, and a code reader is used to read the wafer. Whether the bottom surface height signals of the wafer detected by two sensors are different is used to judge whether the wafer has been thinned. The wafer can be detected while being read, thereby reducing the error rate and improving the product yield. The recognition blind area of the code reader can be eliminated by setting a first camera and a second camera, thereby ensuring the code reading accuracy of the code reader. The placement plate is driven to rotate by a motor, thereby driving the wafer located at the upper end of the placement plate to rotate, and the reading code position on the upper surface of the wafer is adjusted to facilitate the reading of the code reader. When the light is not good, the set fill light can be used for fill light, thereby improving the speed of the code reader in identifying the reading code.
[0004] Although the device has many beneficial effects, the following problems still exist: when reading the code of the wafer, it is difficult for the staff to adjust the distance between the two code readers according to the specific conditions on site, which easily reduces the flexibility of the device when using it. In view of this, we propose a code reading device with a detection function. Utility Model Content

[0032] Reference Figure 2 and Figure 3 The other end of the insertion rod 37 is fixedly connected to a pull plate 38 , and the size of the pull plate 38 is larger than the size of the two ends of the insertion rod 37 , so that it is convenient for the staff to pull the pull plate 38 to move the insertion rod 37 out of the opening 36 .
