Description

Material box conveying device of die bonder

Technical Field

The utility model relates to the technical field of semiconductor die bonding equipment, in particular to a die bonder magazine conveying device.

Background

The die bonder is a common device in a semiconductor production line, and the working process is as follows: the material box with the multi-layer metal frames inside is stored in a material box bin, the material box is conveyed forward to a corresponding supporting mechanism by a conveying mechanism, then the material box is lifted to a proper height by a jacking mechanism, and then the single-piece metal frames are pushed to corresponding stations by a pushing mechanism; and the swing arm takes out the crystal grains on the crystal disc and transfers the crystal grains to the metal frame after dispensing. After die bonding of the single metal frame is completed, the single metal frame is pushed back to the raw material box, and then the height of the raw material box is adjusted, so that the pushing mechanism pushes the next metal frame to the corresponding station to continue die bonding operation. After all the metal frames in one material box are subjected to die bonding, the material box is taken out, the supporting mechanism is unloaded, and then the supporting mechanism is lowered to an outlet of a material box bin through the jacking mechanism to receive the next material box.

In the actual production process, in order to facilitate the storage and taking of the material box in the material box bin, two ends of the material box bin are necessarily open, namely, the inlet is used for throwing the material box, and the material box moves to the supporting mechanism through the outlet at the other end. Because the material box in the material box bin is intermittently pushed forward under the action of the transmission mechanism, when the material box moves to the outlet of the open material box bin, the material box is easily offside to the vertical area of the supporting mechanism due to inaccurate control of the transmission mechanism, and when the supporting mechanism is lowered to the outlet of the material box bin to receive a new material box, the material box is easily collided with the offside material box, so that the die bonding equipment is damaged.
