This article mainly explains the "matters needing attention in the safe operation of SMT mounter". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what matters needing attention in the safe operation of SMT mounter.

Basic process elements of SMT

Printing (or dispensing)-- > mounting-- > (curing)-- > reflow soldering-- > cleaning-- > testing-- > rerepair.

I. matters needing attention in board operation

1. The board should be placed on the track parallel to the track and gently pushed forward.

2. Make sure that the board is placed on the belt of the track when putting on the board. Don't put it askew, causing the track to be pried open. Cause the plate to get stuck, and for a long time it will also cause the track to become a trumpet.

Second, the processing of machine alarm

1 if the on-site operator is familiar with the alarm information and knows the clear treatment measures and implementation results, he can confirm and deal with the alarm fault information by himself. You can refer to Table 1, "key equipment alarm information processing authority (operator)".

2 if the on-site operator is familiar with the alarm information and does not know the clear treatment measures and implementation results, he may not confirm the alarm information by himself, but should protect the alarm information and inform the engineer or technician on the line immediately to deal with it.

3 if the on-site operator is not familiar with the alarm information, it is not allowed to confirm the alarm information on its own. The alarm information should be protected and notified to the engineer or technician on the line immediately.

Third, the protection and treatment of the fault site: it is divided into three situations.

(1) the equipment has abnormal performance in operation. For example, abnormal sound, bad smell, overheating of motor, etc., can be stopped and notified to the line engineer or technician to deal with it; (special attention: when stopping, first make sure that the product being produced has left the area where damage will occur after the shutdown, such as: reflux furnace, wave soldering high temperature zone)

2 after the failure of the equipment in operation, there will be no further harm to the product or personnel. If the motor is stuck, the normal execution action cannot be carried out, the moving parts are damaged or the impact occurs, the crimping is abnormal, the computer crashes are controlled, etc., the on-site operator should stop all operations related to the equipment, immediately notify the on-line engineer or technician to deal with it after protecting the site.

(3) after the failure of the equipment in operation, it may cause further harm to the product or person. Such as: cleaning machine card board, in and out trigger card board, ICT line card board, automatic container operation does not stop, line leakage, etc., the on-site operator should press the emergency stop switch (turn off the power supply), and immediately notify the line engineer or technician to deal with it after protecting the site.

IV. matters needing attention in safe operation of placement machine

Placement machine as a high-tech product, safe and correct operation is very important for both machines and people.

The most basic thing to operate the mounter safely is that the operator should make the most accurate judgment and follow the following basic safety rules:

1. Machine operators should be trained to operate in the correct way.

2. Power should be turned off when inspecting the machine, replacing parts or repairing and internal adjustment (the maintenance of the machine must be carried out when the emergency button is pressed or the power supply is cut off.

3. Make sure that the YPU (programming components) is in your hands to stop at any time when "reading coordinates" and adjusting the machine.

4. Make sure that the "interlock" safety equipment remains effective to stop the machine at any time, and the safety inspection on the machine can not be skipped or short connected, otherwise it is very easy to cause personal or machine safety accidents.

5. Only one operator is allowed to operate one machine during production.

6. During operation, make sure that all parts of the body, such as hands and head, are outside the range of movement of the machine.

7. The machine must be properly grounded, not the zero wire.

Do not use the machine in a gas or extremely dirty environment.

Note:

A) those who have not received training are strictly forbidden to operate on the computer.

B) Safety first, the machine operator should operate the machine in strict accordance with the operating specifications, otherwise it may cause machine damage or endanger personal safety.

C) Machine operators should be careful and careful.

V. explanation and practice of practical operation

1. Explain the operation interface

2. Explain the safety matters around the machine

3. Explanation of machine alarm (throwing material, no material, MARK point, transmission, etc.)

4. Matters needing attention in using FEEDER

5. Matters needing attention on FEEDER
