Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection, and more specifically, to a flatness detection device. Background Art

[0002] Flatness detection is sometimes also called frontality detection or coplanarity detection. A flatness detection system is specifically used to detect various indexes such as the horizontal straightness, coplanarity, gap, and pin width of the pins of various electronic components such as various IC chips and electronic connectors. The flatness detection system has developed from a single-camera flatness detection system to a detection with two cameras, three cameras, and multi-camera linkage. The single-camera flatness detection system can achieve an accuracy of more than 0.01 mm when detecting the calibration flatness, and the flatness error range can be set according to the detection requirements;

[0003] Currently, due to different products to be detected, the positions of the corresponding two-dimensional codes are different, so the position of the barcode scanner needs to be changed. The barcode scanners of the current flatness detection equipment cannot be adjusted correspondingly according to different products, or manual adjustment and installation are required, which is troublesome to operate;

[0004] The Chinese patent with the patent application number CN202221591993.0 discloses a 3D flatness detection device, including: a machine table, on which a fixture platform is installed through a support frame; an X transverse movement module and a Y transverse movement module. For this flatness detection device, when changing different products, the distance between the two barcode scanners can be adjusted through the variable distance module to correspond to the positions of the two-dimensional codes of different products, so as to achieve the purpose of scanning the two-dimensional codes of different products;

[0005] However, it can be seen from the accompanying drawings of its specification that the height and the front and rear positions of the detector are fixed relative to the height of the fixture platform and do not have an adjustment function. When the sizes of the workpieces on the surface of the fixture platform are different, it is inconvenient to adjust the height and the front and rear positions of the detector according to actual needs, which affects the detection use effect.
