Description

Technical Field

[0001] The utility model relates to the technical field of chip processing and fixing, in particular to a clamping device for positioning and fixing chips. Background Technique

[0002] In the chip grasping and testing technology, it is often necessary to fix the chip during the grasping process to ensure that subsequent functions and quality are not affected during related operations. During the process of chip detection and fixing, it is also necessary to clamp and fix the circuit board used for detection.

[0003] Existing clamping devices have certain limitations in practical applications. These devices usually fix the circuit board by designing clamping grooves that match the size of the circuit board. During installation, the user only needs to align the circuit board with these clamping grooves and then press down directly to fix the circuit board. This design can indeed meet the requirements of limit fixing to a certain extent and ensure that the circuit board does not shift during use. However, if the clamping device cannot flexibly adjust the clamping position, then the picking up and placing of the circuit board before and after installation will become relatively difficult. When the size or shape of the circuit board changes slightly, the original clamping grooves may no longer be applicable, and the user needs to find a suitable position to fix the circuit board again. This not only increases the complexity of the operation but also may lead to a reduction in the installation efficiency, and thus optimization and improvement are required.
