Person in charge of the project timeintender inspector level 1 maintenance each shift operator production supervisor level 2 maintenance monthly operator production supervisor level 3 maintenance semi-annual after-sales manager 4. Maintenance supplies vacuum cleaner, dust-free paper, rags, brushes, alcohol, lubricating oil (NSL) 5. First-level maintenance content 1.Clean the surface of the machine with a clean rag dipped in alcohol 2.Check whether the input air pressure is normal (0.40-0.55MPa)3.Remove the throwing box material 4.Clean the dirt inside the machine and the material parts that fly off 5.The suction nozzle status confirmation 1).Open the [Device]-[HEAD] tab screen, press the [Initialize] button at the bottom right of the screen, refresh the vacuum level value. 2). In the [Device] - [HEAD] tab screen, open all the placement head [Inhale] buttons, after the value rises, turn off the button after 5-10 seconds. Reading the value of the [maximum value], below 110 is a normal value, and if it is greater than 110, the nozzle hole may be dirty and the nozzle needs to be cleaned. SMT Machine Nozzle 6.Clean feeder holder 1) Sweep the feeder holder with a included soft brush. If there are smd elements and foreign objects falling on the feeder rack, when the feeder is installed, it will cause the adsorption position to be offset and cause damage to the feeder. 2) Check whether there are any adhesion elements under the material gun. Figure 2: Clean the feeder rack 7.Use a magnifying glass to check whether the tip of the nozzle is dirty. As shown in Figure 3, the state of the suction nozzle Figure 4 The dirty suction nozzle is removed and removed, and the surface and interior of the suction nozzle are cleaned with alcohol until the surface of the suction nozzle is clean and the internal blowing is unobstructed. Sixth, the second level of maintenance content: before maintenance, please press the emergency switch button (to ensure safety, to prevent the machine from suddenly starting) 1. Check whether there are foreign objects such as patch elements adhered to the screw and linear guide rail? In an emergency shutdown state (pressing the emergency stop button), push the X or Y axis with your hand to check whether the screw screw is making any abnormal noise. 2X, Y, W, PU shaft screw screw cleaning, refueling 1) move each shaft to one end with a moving handle 2) Wipe off the dirty lubricating oil and other dirt of the screw screw, linear rail full rod with dust-free paper, etc. 3) After moving each shaft to the other end, wipe the spiral screw at the other end and the full rod of the linear guide rail with dust-free paper. (X-axis Y-axis W-axis PU shaft) Wipe spiral screw with dust-free paper etc. Wipe spiral screw 4) Apply lubricating oil X and Y axis lubricating oil gun, and inject the designated lubricating oil (NSL) from the lubricating oil injection nozzle. Apply the specified lubricating oil in the groove of the screw screw with your finger, after moving the shaft by hand, wipe off the excess lubricating oil W shaft The specified lubricating oil (NSL) is evenly applied with your fingers on the surface of the screw screw and the pu shaft of the spiral groove part with your fingers Dipped in about 2cm Of the new lubricating oil is evenly kneaded into the spiral groove part of the spiral screw To confirm the vacuum degree of the vacuum solenoid valve Confirm the vacuum degree of the vacuum solenoid valve Seven. Three-level maintenance content: before maintenance, please press the emergency switch button (to ensure safety and prevent the machine from suddenly starting) 1 vacuum solenoid valve filter cleaning and replacement 1) Move the placement head to the center of the two rails of the Y axis and press the [Axis Movement] button of the [Device] - "Head" (or "Conveyor") tab screen, open the "Axis Movement" screen, move the placement head to the center of the two rails of the Y axis 2) Disassemble the filter cover and loosen the filter cover with a slotted screwdriver and remove it 3) Remove the filter with forceps, when there is only a small amount of dirt, you can use the air gun to blow away and reload the drain. 4) Install the filter: embed the filter with the O-ring into the filter cover and insert it into the drain, rotate to the right and lock the filter cover. (Make a "click" sound) 5) Vacuum solenoid valve vacuum check (1) Pull out the gas pipe of all placement heads from the airtight joint in the lower part of the vacuum solenoid valve (2) Confirm the vacuum degree of a single vacuum solenoid valve, open the [device] - "Head" tab to plug the airtight joint with your fingers for all placement heads, and press [Inhale] button. Record the maximum value of the airtight joint in the closed state, confirm whether the vacuum degree of the vacuum solenoid valve is confirmed above the measurement reference value 2.Cleaning in the spline shaft 1) Move the placement head to an easy-to-operate position 2) Remove the suction nozzle on all placement heads 3) Pull out the gas pipe inserted in the upper part of the spline shaft of each placement head 4) Remove the 4 bolts that fix the vacuum solenoid valve device frame with a hex wrench 5) Inject IPA (isopropanol alcohol) into the cleaning container Pad a dust-free cloth just below the working position 6) Remove the spring from the spring hook by hand 7) Remove the fastening bolt with a precision wrench (6 corners) 8) Insert the nozzle of the cleaning tool into the air passage of the IPA to clean the multi-slot shaft 9) Prepare the air gun, block the position of removing the tightening bolt with the cleaning with your hand to prevent air leakage, one While blocking the front end of the multi-slot shaft with a dust-free cloth, while implementing jet chip evacuation in the multi-slot shaft to confirm that the dust-free cloth blocking the front part of the multi-slot shaft is no longer dirty, install the fastening bolt 10) Hang the spline shaft spring on the spring hook by hand. 11) Repeat the operation of steps 7-11 to clean the spline shaft inside all placement heads. 12) Tighten 4 bolts with a hex wrench to fix the vacuum solenoid valve device frame. 13) Put the trachea and suction nozzle back in place. Put the gas pipe and suction nozzle back in place Put the gas pipe and suction nozzle back into place Spline shaft refueling 1) Turn off the power supply of the placement machine, make the spline shaft run by hand, confirm that there is no abnormality by moving the spline shaft up and down by hand, confirm that there is no abnormality in terms of action and abnormal noise compared with other multi-slot shafts, 2) Wipe the multi-slot shaft with dust-free paper and cotton swabs that do not produce dust 3) Apply lubricating oil on the multi-slot shaft with your hand on the surface of the spline shaft, evenly apply a thin layer of lubricating oil 4) Move the spline shaft several times by hand and wipe the excess lubricating oil with dust-free paper Eight. Precautions: 1 Precautions on machine operation Do not use an airsoft gun when cleaning the machine. (Dust scattering, will cause adverse effects on the machine) When cleaning the machine nearby, it must be carried out in a shutdown state of the machine, do not cut off the air source during operation 2 Precautions in the event of a power outage If the power is out in automatic operation, the main control switch must be placed in the OFF state to avoid misoperation and machine damage after power-on, in addition, if there is a substrate left in the machine, it must be taken out 3. Before starting the equipment, it must be checked whether there is a tool forgotten in the machine.
