AI Technical Summary

Technical Problem

Existing syringe filling equipment occupies a large space, has a complex structure, and is prone to damage during the pressing of the rubber stopper.

Method used

The system employs a tray slide and a rubber stopper pressing mechanism. The entire tray of syringes is positioned by the tray receiving groove on the tray slide, and the rubber stopper is smoothly installed by using the vacuuming of the transition connecting sleeve and the synchronous action of the rubber stopper push rod. Combined with the filling mechanism and the rubber stopper feeding mechanism, efficient filling and rubber stopper pressing are achieved.

Benefits of technology

The equipment has a compact structure, occupies little space, has high filling efficiency, low stopper damage rate, extremely high production efficiency, and low cost.

Abstract

The utility model discloses automatic filling equipment for syringes. Comprising a filling rack, a tray sliding plate horizontally and linearly installed on the filling rack in a sliding mode, a tray positioning mechanism used for braking and positioning trays in tray containing grooves in the tray sliding plate, a tray feeding and discharging mechanical arm used for feeding and discharging the tray containing grooves, and a sliding plate driving device used for driving the tray sliding plate to slide intermittently. The device comprises a tray sliding plate, a filling mechanism used for filling liquid medicine into a row of injectors in a tray located on the tray sliding plate, a rubber plug feeding mechanism used for placing rubber plugs at the opening ends of the row of filled injectors, a rubber plug pressing mechanism used for pressing the rubber plugs into the injectors by set depth, a manipulator used for controlling feeding and discharging of the tray, and a tray positioning mechanism. The automatic filling device for the rubber plug is compact in structure, small in occupied space, high in filling efficiency of the injector and capable of preventing the rubber plug from being damaged when the rubber plug is pressed.
