Personalized automatic customization method and apparatus for a ring-pull can

1. A personalized automatic customization apparatus for a ring-pull can, comprising: a bin device, a distributing device, a pushing device, a positioning device, a discharging device and a control system, wherein the bin device is located at an upper part of the apparatus, the distributing device is installed below the bin device, and the pushing device is arranged on a side of the distributing device and the positioning device; and the bin device, the distributing device, the pushing device, the positioning device and the discharging device are respectively electrically connected to the control system, wherein,

in the bin device, a bin employs a V-shaped structure, an upper portion of the bin is free of lid, a lower portion of the bin is provided with an outfeed opening, a bin door is able to be opened, and the bin door is provided with an elongated hole;

the distributing device is mounted below the outfeed opening, and includes a feeding wheel which is machined with a nylon block, and the feeding wheel includes four semicircular feeding grooves arranged at equal intervals around an axial direction of the feeding wheel, and the feeding wheel is driven to rotate by a motor, and a chute is mounted below the feeding wheel, and the chute is connected to a U-shaped groove arranged below the chute;

the pushing device comprises a pushing motor and a screw rod, wherein the screw rod can be driven by the pushing motor to push the ring-pull can to a marking position and a discharging position;

the positioning device employs a roller type rotation mechanism, and comprises two positioning rollers, a motor is mounted below the two positioning rollers, the motor drives the two positioning rollers to rotate by means of a belt, and a positioning sensor is mounted above a first side of each of the two positioning rollers;

the pushing device is located on a common side of the U-shaped groove and the positioning device, the pushing device is an electric linear actuator, the screw rod is mounted on a sliding block of the pushing motor, and a tail end of the screw rod is a pushing plate;

an electric push rod is mounted on a rear side of the discharging device, a U-shaped discharging hopper is mounted at front of the electric push rod, and the U-shaped discharging hopper is mounted on a sliding plate.

2. A personalized automatic customization method for a ring-pull can, comprising steps of:

setting a pattern of a marking content on a control system, and inputting the marking content on the control system;

driving a feeding wheel of a distributing device by a feeding motor to rotate through a quarter turn per time under control of the control system, and providing one ring-pull can per quarter turn to fall into a pushing device arranged on a side of the distributing device and a positioning device;

driving a screw rod by a pushing motor in the pushing device, to push the ring-pull can to the positioning device;

rotating the positioning device, to trigger a positioning sensor above positioning rollers of the positioning device to send a signal which indicates successful positioning;

receiving the signal by the control system, and driving a laser head above the positioning rollers to mark the marking content on an outer surface of the ring-pull can;

driving the screw rod by the pushing motor to move forward, so as to push the ring-pull can towards a chute at one end of the screw rod which is away from the pushing motor; and

extending an electric push rod out of an electric cylinder by an electric push cylinder to push forward a discharging hopper, which receives the ring-pull can falling along the chute, wherein the discharging hopper is below the chute, the electric push rod is mounted on a rear side of the discharging device.
