Background

After the chip is produced, the chip is usually required to be tested and sorted, and the chip is classified into different class grades according to sorting and testing results and is put into different trays for storage. The existing tray taking and taking mode is that a tray carrying mechanism takes out a tray from a bottom stock bin, the tray is put into an intermediate tray, and then the tray supports the tray to be lifted to a fixed taking position for a manipulator to take out materials to be produced in a subsequent process; the discharging and discharging mode is that the mechanical arm takes materials from the previous working procedure and discharges the tray, then the tray descends to a discharging position on the tray, and then the tray is conveyed to the storage bin for storage through the tray conveying mechanism.

When the manipulator takes out the chip from the tray, the manipulator has higher requirements on the position of the chip, so that the tray needs to be positioned so as to prevent the position change of the tray from affecting the material taking of the manipulator. At present, the existing positioning mode for the tray is usually realized by matching a positioning pin arranged on a tray for bearing the tray with the tray, however, the positioning mode cannot eliminate a gap between a linear guide rail sliding block and a guide rail when the tray is lifted or lowered, and particularly, the service time is long, and after the guide rail is worn seriously, the positioning precision of the tray on the tray can be greatly influenced.
