SMT Industry Introduction
Surface Mount Technology, or SMT for short. As a new generation of electronic assembly technology, it has penetrated into various fields. SMT products have the advantages of compact structure, small size, vibration resistance, and high production efficiency. SMT has occupied a leading position in the circuit board assembly process. The main equipment of SMT assembly line: printing machine, placement machine, reflow soldering, etc.
SMT machine detailed operation tutorial
1). Preliminary inspection
1. Check whether the barometer of the placement machine is between 0.40-0.55Mpa and whether the power connection is normal.
2. By checking the temperature and humidity meter hanging on the production site, confirm that the temperature and humidity meter of the working environment is within the specified range of temperature 20-28 ℃, 50-60 atmospheric humidity), and adjust immediately if the working environment changes.
3. Do a good job of the 6S standard for machines and jobs, check whether there are foreign objects inside, and whether there are foreign objects in the moving parts such as guide rails, conveyor belts, placement heads, supports, and their movement ranges, and clean them up in time. Whether the emergency stop button is reset, and whether the front protective cover is closed normally.
4. Confirm that the machine feeder is firmly fixed on the feeder and does not float. There are no foreign objects on the feeder.
5. Confirm that there is no defect in the suction nozzle, sticky cream, and poor rebound.
2）. Operation steps
1. Start
(1) Turn on the main control power switch of the placement machine and turn the main control power switch to the right so that the switch arrow points to the ON position, the main control power is turned on, the placement machine host is powered on, the computer is started and the device hardware detection is performed (automatic completion), After loading the program required for the machine to run, the Initializing page is displayed.
(2) After the initialization of returning to the origin is completed, click the button of returning to the origin with the mouse, the device will automatically perform the operation of returning to the origin, and automatically enter the interface after the completion of the return to the origin.
2. Warm up
The first step is to click the warm-up button to enter the warm-up interface.
The second step, on the warm-up interface, click Stop at the specified time.
The third step, enter the warm-up time in the warm-up time text box, usually 10 minutes.
The fourth step, click start, the placement machine enters the warm-up operation. The fifth step, after the warm-up is completed, click the close button to complete the warm-up and return to the main interface.
3). Production
(1) Select the substrate program In the first step, the user clicks the substrate selection button on the production design page to enter the substrate selection window; in the second step, in the substrate selection window, find the patch program to be produced and click to select, and then click the selection button , to complete the substrate selection operation, the machine reads the substrate data and returns to the main interface.
Adjust the guide rail Click the button of Device-Conveyor-Transmission Width on the main interface to enter the transmission width interface, input the width of the substrate in the changed transmission width, click the OK button to adjust the width of the guide rail, and the user will put it from the docking station rail. After transferring the substrate to the placement machine track, push the substrate back and forth by hand to confirm that there is a tiny gap of about 1mm between the substrate and the transfer track.
4). Check the production design button on the main interface of the material point, click the button in the lower left corner (feeder list), move the scroll bar to view the material position in the feeding list window, and install the feeders in sequence according to the installation position.
Steps to install the feeder:
①Press the emergency stop button and open the top cover of the machine. If the feeder is installed without stopping the operation of the placement machine, there is a danger of being caught in the placement machine.
②Remove the dust on the feeder frame If the feeder is caught in components or dust, the feeder will be inclined and the adsorption will be unstable.
③Install the feeder Lift the handle of the Feeder upward, align the feeder installation position, and insert it into the positioning hole while sliding on the guide rail.
④ Confirm the installation status of the feeder, whether the cover tape is loose, and whether it has been inserted in place accurately.
5). Start production
①Release the emergency stop button and press the READY button on the operation panel to power on the servo motor.
②Press the START button on the operation panel after confirming the safety.
③ After the entrance sensor senses the substrate, the conveyor belt starts to rotate, transfers the substrate to the working position, and begins to mount components.
④When the green indicator light is on (in automatic operation), it is strictly forbidden to enter the movable range of the placement head.
6). Shut down
(1) Save the program After the production is completed, press the SOTP button on the operation panel to exit the production state, click the substrate save button on the interface, open the substrate save window and click the close button in turn to save the substrate data.
(2) Turn off the host Click the power-off button on the interface, follow the prompts in the pop-up dialog box, and turn off the main control power switch when the display shows restart.
