Full decryption of the structure of the automatic screw feeder: a guide to precise adjustment from the 0.5mm gap of the electromagnet to the 5Bar air pressure

When purchasing Xiaomao Automation's automatic screw locking machine, some customers will want to know the structural diagram of the equipment. However, the structural diagram can often only show the approximate appearance of the equipment. In order to have a deeper understanding of the structure of Xiaomao Automation's automatic screw locking machine, especially its core feeding system, we will introduce the structure and function of its main components in detail here.

Overall structure of Xiaomao Automation's automatic screw locking machine
Xiaomao Automation's automatic screw locking machine is mainly composed of a control system, a feeding system, and a locking execution system. This article will focus on the detailed analysis of the feeding system.

Spiral feeding structure
The spiral feeding structure of Xiaomao Automation's automatic screw locking machine is centered on the spiral feeder, which is responsible for the orderly delivery of screws.

Tail structure:
1.Arc plate return device: guides unsuccessfully locked screws back to the screw barrel for recycling.
2.Screw barrel: As a storage container for screws, it is placed directly on the roller bracket.
3.Driving roller: driven by the transmission motor through the universal joint, driving the spiral drum to roll up and down.
4.Universal joint: realize power transmission between the transmission motor and the drive roller.
5.Brush: used to unscrew the screw from the straight channel and send it back to the screw barrel to ensure the smoothness of the screw delivery.

Screw feeding part:
1.Separator: separate the screw from the screw barrel to prepare for subsequent distribution.
2.Distributor: distribute the separated screws to each blow pipe to ensure uniform delivery of the screw.
3.Blow pipe: use air pressure to blow the screw to the screw delivery pipe.

4.Screw delivery pipe: deliver the screw to the locking actuator to complete the locking task.

In this process, the screw of the straight channel is transmitted to the distribution port through the vibrator, and the separator cylinder pulls the screw to the pipe mouth, so that it falls into the pipe, and then blows it out through the blow pipe, and finally blows the screw accurately to the locking mechanism.

Feed channel structure:
1.Screw full material sensor: senses the full and empty state of the screw in the straight material channel, turns off the screw light when the channel is full, lights up the screw light when it is empty, and stops the machine when the full screw supply is insufficient.
2.Linear vibrator: provides forward power for the screw to ensure smooth movement of the screw in the channel.
3.Pressure plate and material channel acceleration tube: work together to prevent the screw from being squeezed during transportation, ensuring the integrity and transportation efficiency of the screw.

Adjustment of related components and linear vibration feeding part
Electromagnet adjustment:
1.Fix the lower part of the electromagnet to the bracket of the machine.
2.Place the armature of the electromagnet directly above the electromagnetic coil.
3.Use the screws on the upper and lower electromagnets to pre-lock the spring sheets on both sides of the electromagnet.
4.Adjust the distance between the electromagnetic coil and the armature to ensure that it is between 0.5 and 1.0 mm.
5.Install the screw guide seat and guide rail to ensure accurate delivery of the screw.

Air pressure adjustment:
1.Pull up the regulating valve knob and turn it to the right.
2.Observe the pressure on the air pressure gauge until it reaches 5 bar.
3.Press the knob after the adjustment is completed to fix the air pressure value.

Distributor adjustment:
1.Install the components of the distributor.
2.Install the distributor to the bracket of the machine.
3.Make sure that the distribution screw inlet is well connected to the linear vibration feed track and the height is the same.
4.Adjust the position of the pressure plate above the linear vibration feed track to ensure that the lower surface of the pressure plate is

0.5 to 1.0 mm higher than the upper surface of the nut.

Brush height adjustment:
1.Observe the status of the brush and adjust its height as needed.
2.Make sure that the brush can sweep down the screws on the side of the material path, but it does not need to be adjusted too high or too low.

The above is a detailed introduction to the feeding system of the Xiaomao Automation automatic screw locking machine. By understanding the structure and working principle of these components, customers will be able to have a more comprehensive understanding of our equipment and make a more informed purchasing decision.
