Description

Technical Field

[0001] The utility model relates to the technical field of motherboard production, in particular to a positioning device for motherboard production. Background Art

[0002] The motherboard, also called the motherboard, is installed in the computer mainframe. It is one of the most basic and important components of the computer and plays a pivotal role in the entire computer system. The quality of the motherboard determines the stability of the hardware system. During the production and processing of the motherboard, a positioning device is often required to fix the motherboard so as to facilitate welding or grinding of the motherboard.

[0003] Chinese utility model (publication number: CN217072152U) discloses a positioning device for computer motherboard production. The computer motherboard is placed on the upper end of the clamping platform, and the transmission rod is pulled to drive the rotation of the turntable. Since the connecting slider is slidably connected with the arc groove excavated at the upper end of the turntable, when the turntable rotates, it will drive multiple connecting sliders to slide toward the middle at the same time, and push the clamping baffle to clamp the computer motherboard. At the same time, when the triangular clamping block at the outer end of the turntable rotates, it will push the rotating clamping block to rotate into the fan-shaped groove, so that the spring piece is squeezed and deformed. When the highest part of the triangular clamping block slides over the rotating clamping block, the spring piece resets and pushes the rotating clamping block to be clamped on the surface of the triangular clamping block, limiting the triangular clamping block, so that the turntable is not easy to rotate clockwise, and the turntable is fixed, so that the device is not easy to loosen after clamping the computer motherboard.

[0004] Since two surfaces of the motherboard need to be processed in the actual operation process, when the above device is used, after one surface of the motherboard is processed, the motherboard needs to be removed from the positioning device, turned over and re-fixed, that is, the motherboard is fixed twice, which is inconvenient. Therefore, how to design a positioning device for motherboard production has become a problem that we need to solve at present. Utility Model Content
