How to prevent static electricity in the process of SMT placement machine?
In the SMT production line, we will encounter the problem of static electricity, from the friction between the clothes and the dry air to the dry air, which is the end of the duckweed. If the condition is suitable, it is a few volts and the peak is hundreds of kilovolts, so anti static is the need to do in our work, today, the south. Give some measures to introduce mechanical anti electrostatic patch SMT.
Static electricity has three: static clothing, antistatic shoes (conductive shoes), electrostatic hand rings, antistatic shoes and electrostatic hand rings to guide the human body to avoid accumulation in the human body.
Ordinary clothes will have great electrostatic voltage in the walk (>1000V). And antistatic clothing does not happen when it moves. This is the main role of antistatic clothing, long strip antistatic clothing can not shield the inside of the clothing produced static (after wearing still >1000V), grid – like antistatic clothing can be shielded (<200V), the static electricity generated through the floor and the grounding line of various parts of the plant to the outside of the general grounding wire.
1, strengthen the consciousness of the workers on the anti static operation
2, reduce the poor production caused by static electricity
3, prevent static electricity from causing damage to the product
二，Scope of application: all SMT production lines
The generation of static electricity is not perceived, but the static electricity produces the voltage of tens of thousands of volts. When the static electricity comes into the tip (the static release point, such as the human finger), it releases all the energy in a moment, causing the contact material to be struck by electric shock, causing the capacitance, IC, line road and so on to be destroyed and burned, so that the product is strict. In the case of heavy damage, static electricity measures should be taken. .
四，The contents of the operation
（一）Prevention and treatment of human static electricity
1, the workers should wear electrostatic clothing, work shoes;
2, the operator should take electrostatic gloves when working.
3, the operator should take an electrostatic ring in the operation.
（二）Prevention and control of static electricity
Make use of electrostatic materials to produce production tools.
2, the storage place to prevent static electricity;
（三）Prevention and control of static electricity of a worktable / mobile vehicle
1, the anti static film should be pasted on the work table.
2, the operation platform / mobile vehicle must have antistatic grounding chain.Prevention of equipment static electricity: good grounding wire
（四）Prevention and control of material static electricity
When the material is taken, the operator should use the antistatic method: with electrostatic gloves and electrostatic rings.
2, the material storage should be anti static measures: material cabinet to paste electrostatic film, grounding chain.
3, there should be anti-static measures in temporary storage area: installing grounding chain.
（五）Prevention and control of static electricity related to production: anti static measures should be taken when using items related to production: static wires and antistatic films.
The online operators should strictly abide by this rule
The online operators are supervised by the team leader, and the engineers are supervised by the engineers.

Troubleshooting E-Stop and Interlock Circuits
On the Machine
Prerequisite setups and materials
These setups and materials are required before this module is presented:
IM8ECTT Study Guide (1 per trainee)
Machine in operating condition
The E-Stop and interlock circuits on Universal‘s products are designed to ensure that axis operation can occur only when these safety circuits are satisfied. The E-Stop and Interlock safety circuit is hard-wired and will perform its function independent of machine software.
In this lesson, you will look at the E-Stop and Interlock safety circuit in detail. Once you understand how it works you will get some practical experiences in troubleshooting this circuit.
Trace E-Stop/Interlock circuit at machine and check the Interlock system with the job aid provided.
Given a machine with a fault in the E-Stop/Interlock circuit, locate and repair the fault using information in the study guide and the MSD.
Instructional Strategy for the module
Discuss European Safety Standards
Discuss sequence of events of E-Stop and Safety interlock and how they relate to power distribution
Trace the troubleshooting steps:
European Safety Standards
European Safety Standard
Universal‘s E-Stop and Interlock circuit is in compliance with European Safety Standards, which include the following requirements:
Use of redundancy (i.e., two mechanical relays to disable dangerous voltages)
Use of contacts which move together and are positive guided (no contact can be in the de-energized state if one contact is stuck in the energized state)
All relays must have a normally closed contact used to test the relays.
the E-Stop and Interlock Circuits
This activity is intended to give you some practical experiences in troubleshooting the E-Stop and Interlock Circuits on a machine. In this activity your instructor will put one or more bugs in the machine E-Stop and Interlock circuits. Your job is to find and fix the bugs so that the machine is returned to normal operation.
High voltage is present on the machine when power is turned on. Take great care when troubleshooting the electrical assemblies in the machine!
Whenever possible, never reach into an electrical assembly when the machine power is on.
Use extreme caution when connecting or disconnecting a multimeter. When the situation warrants, use test probe clips to connect the multimeter to test points with power off at the assembly*, then apply power to read the meter; and turn assembly power off before disconnecting the meter.
*An E-Stop or circuit breaker can often be used to remove assembly power.
Working in a small group (never alone), locate and repair the bugs put into the machine by the instructor. The machine must be returned to normal operating condition when you have completed your work.
It is strongly recommended that you follow a sequence when troubleshooting the E-Stop and Interlock system. The Troubleshooting Flow Chart on the following page should help you determine what part of the subsystem is not working.
When looking for machine-specific information, always refer to the electrical diagrams that come with the machine on which you are working.
