Abstract

The invention discloses a system and method for detecting position offset of a chip. The system comprises the following parts of a chip conveying device comprising a guide rail and a jig mounted on the guide rail and movable along the guide rail; a chip detecting device comprising a sensor mounting structure disposed along both sides of the rail and a light curtain shooting sensor coupled to the sensor mounting structure; and a position correcting device comprising a vibrating mechanism with a fixed connection to the jig. The system and method provided by the invention greatly improve the detection precision and can avoid the leakage detection phenomenon of the existing point or line sensor by setting the light curtain shooting sensor, and can vibrate the chip with position offset to flatin time, avoid the chip with position offset from flowing into the next process to damage the chip and improve the automatic detection efficiency by setting the vibration mechanism connected to the jig.

Description

technical field [0001] The invention relates to the technical field of chip detection, in particular to a system and method for detecting chip position deviation. Background technique [0002] In the production process of the chip, after the chip is placed in the groove of the jig, it is necessary to test chips of different sizes and thicknesses according to the testing requirements. At present, point or line-to-shoot sensors are mainly used to detect the presence or absence of chips and the phenomenon of positional deviation. However, there are obvious loopholes in this method, especially when detecting chips with small size or serious position deviation, it is easy to miss detection. Therefore, it is necessary to adopt a new detection method to avoid the disadvantages of point and line-to-shoot sensors. Contents of the invention [0003] The object of the present invention is to provide a system and method for detecting chip position deviation, avoid the missing detect...
