[0002] With the development of chip technology, chips are gradually moving towards integration, miniaturization and high speed. Chips are also called microcircuits, microchips, and wafers. In electronics, chips are a way to miniaturize circuits (mainly semiconductor devices, but also passive components, etc.) and are often manufactured on the surface of semiconductor wafers.

[0003] Currently, in the chip production process, the chip needs to be burned, and burning is mainly used to burn and write control programs and data into blank chips.

[0004] The chip is sucked and placed in the burning seat for burning. In this process, when the nozzle sucks the chip from the tray / tape / tube, there is a certain gap between the chip and the center of the nozzle in the cavity of the tray / tape / tube. After the suction action is completed, there is a certain deviation between the center of the chip and the center of the nozzle in the XY direction. If the chip is directly placed in the cavity of the burning seat, there will be a problem of chip placement deviation. The placement position of the chip needs to be positioned and calibrated.

[0023] (3) The moving plate is driven to move by an electric telescopic rod, and the meshing connection between the moving teeth and the rotating teeth is utilized so that the electric telescopic rod drives one moving plate to move, thereby driving the other moving plate to move.
