Tray charging method and vibratory tray charger

Abstract

The invention discloses a tray charging method and a vibratory tray charger. The method comprises that: a hopper type vibrating device conveys integrated circuit blocks in accordance with position and direction requirements to a gripping reference position of a conveying guide rail corresponding to a fixed gripping position one by one; a tray adaptive charging device conveys troughs on a tray to a placing reference position corresponding to a fixed placing position one after another; a suction nozzle of a gripping and placing device reciprocates between the fixed gripping position and the fixed placing position according to a fixed path, and grips the integrated circuit blocks reaching the conveying position of the vibrating device when reaching the gripping position; then, the suction nozzle of the gripping and placing device moves the placing position; and when reaching the placing position, the suction nozzle places the integrated circuit blocks sucked by the suction nozzle into the troughs reaching the conveying position of the charging device. The method can improve the stability of the tray charger under the cooperation of the gripping and placing device and the charging device, and limit the total stroke of the suction nozzle to minimum.

Description

technical field [0001] The invention relates to a tray loading method for integrated circuit blocks and a tray loading device capable of realizing the method. Background technique [0002] The integrated circuit chips produced in batches need to be arranged on the tray according to the front and back sides and the same direction before being sent to the next process for processing, weaved into the braid, or loaded into the material tube. [0003] At present, most of the methods of loading integrated circuit chips into trays rely on cheap labor for tray loading. However, with the shortage of labor market and the increase of labor costs in recent years, as well as the improvement of the quality requirements for tray loading, Many chip manufacturers hope to have a tray loading machine that can replace manual tray loading with low cost, high efficiency and good quality. [0004] The key issue of tray loading is to realize the accuracy and stability of the material grabbing and ...

Problems solved by technology

[0004] The key issue of tray loading is to realize the accuracy and stability of the material grabbing and discharging positions. The key issue of tray loading is to realize the accuracy and stability of the material grabbing and discharging positions. The position of the suction nozzle is fixed, and the discharge position of the suction nozzle changes with the position of the tray trough. In this way, the structure of the grasping and discharging device that drives the suction nozzle is complex and large in size, and the cost is high. Moreover, the moving distance of the suction nozzle changes each time. The total stroke of the movement is large, which affects the stability and efficiency of the suction nozzle
