Routine management and maintenance of the bonder?

The reflector plate plays a critical role in detecting component electrodes, component sizes, and nozzle numbers. If any of these functions are poorly recognized during the placement process, the reflector plate and reflector cap should be inspected and, if necessary, replaced.

Filters are essential for compressing and filtering air, ensuring the cleanliness of the compressed gas. If the filter becomes dirty, its effectiveness diminishes, impacting the suction power of the nozzles, which directly affects placement accuracy. It's crucial to develop a habit of regularly replacing filters, typically on a monthly basis, as they are consumable parts. Keeping an adequate supply of spare filters is recommended.

Conveyor belts are used to transfer target boards during the mounting process. Over time, they wear out and may eventually break. To ensure uninterrupted operation, it’s necessary to have at least one spare conveyor belt readily available and additional spares for parts that experience frequent wear.

Cylinders:
Cylinders, often used in conjunction with solenoid valves, are responsible for lifting and stopping in the mounter. Common issues include:

  1. Unclean compressed air, leading to sluggish or incomplete cylinder extension and retraction. This should be addressed by cleaning the affected parts.
  2. Air leaks, possibly due to aging seals, which should be replaced.
  3. Piston wear, requiring cylinder replacement.

Bearings are standard parts used extensively in the mounter’s structure. Over time, they can wear out. Regular inspections are necessary, and if radial play is detected, which could disrupt the equipment’s normal operation, the bearings should be replaced immediately. This applies to both joint bearings and rolling bearings.

A synchronous belt consists of an annular belt with equally spaced teeth on its surface that mesh with a corresponding wheel. It offers high transmission efficiency, typically up to 98%, and features a compact structure suitable for multi-axis transmission. Since it operates without lubrication, it’s ideal for working in environments that require minimal contamination.

How to deal with SMT bonder production run alarm?

A. Issues with PCB Transmission:
If there are problems with the smooth transmission of PCBs or if abnormal PCB sizes are detected, report the defective products to IPQC for inspection. Simultaneously, inform technicians to address and improve the issue.

B. Track Problems with the SMT Mounter:
If there are issues with the SMT mounter’s track, notify technicians so they can make the necessary adjustments.

If the vacuum is insufficient due to a clogged suction nozzle or vacuum line, notify the technician to either replace the suction nozzle or clean the nozzle and vacuum line.

Check the machine's air supply connector for any leaks. If a leak is detected, notify a technician or engineer for immediate resolution.

If a manual shift overflow occurs, it may be normal after startup and operation. However, if it happens during operation, notify an engineer for inspection.

  • A. If an operating error occurs, notify the technician to reload the materials and restart the process.
  • B. If there is an abnormal stoppage, inform the technician for further action.
  • A. If a nozzle is defective, stop the machine and inspect the components corresponding to that nozzle.
  • B. If the vacuum is insufficient, notify the technician to conduct a vacuum check.
  • C. If the PCB is not properly fixed, inspect and correct the PCB's positioning.
  • A. If the fixed position is consistently off, have a technician adjust the coordinates.
  • B. If the PCB is not properly fixed, leading to an uneven surface, mounting sinking, or shifting, re-adjust the positioning device.
  • C. If poor solder paste adhesion is causing issues, have a technician or engineer analyze and address the problem.
  • SMT mounter operators must undergo training in the correct operation methods.
  • When checking the mounter, replacing parts, or performing repairs and internal adjustments, ensure the power is turned off. (Machine maintenance must be done with the emergency button pressed or the power off.)
  • Ensure that you can "read coordinates" and stop the bonder's (programmed parts) movement at any time during adjustments.
  • The "interlock" safety equipment must remain effective to stop the machine instantly. Safety tests should never be bypassed or short-circuited, as this could lead to personal injury or machine damage.
  • Only one operator is permitted to operate a machine during production.
  • During operation, all body parts, such as hands and head, must remain outside the machine’s range of motion.
  • The SMT equipment must be correctly grounded (proper grounding, not just connected to the neutral line).
  • Do not use the machine in environments with gases or extreme dirtiness.
  • Check the SMT mounter for any internal impurities or foreign objects and clean them promptly.
  • Ensure there are no abnormalities in the placement of the Fidelity.
  • Verify that the configuration and status of the suction nozzle are normal.
  • Check that the safety guard is functioning correctly.
  • Inspect the area around the equipment for any safety hazards.
  • Follow the SMT equipment safety operation specifications to power on the SMT mounter, and ensure the air pressure and rated voltage are normal before turning it on.
  • Check that the vacuum pressure of the SMT mounter meets the equipment requirements. The vacuum value is typically around 5.5 bar.
  • Activate the mounter’s servo system.
  • Reset the mounter’s X and Y axes to their initial home positions.
  • Adjust the width of the SMT mounter’s guide rail according to the width of the PCB. The guide rail width should be 1mm wider than the PCB to ensure it slides freely.
  • Set the PCB positioning device accordingly.

What are the main accessories of SMT mounter?

Vacuum signal generators 7. photoelectric sensors 8. cylinders 9. conveyor belts 10. solenoid valves 11. high-performance industrial control machines12. and other essential components.

What should I do if I encounter insufficient air pressure in my bonder?

When the air pressure is either lower or higher than the target value, the bonder will sound an alarm. Common causes of low air pressure include deformation, damage, clogged nozzles, insufficient air supply, or air leaks, which can prevent the nozzles from properly picking up or placing materials. If the nozzles are not functioning correctly, they may need to be replaced frequently. Regular maintenance is essential to ensure the bonder operates smoothly during the placement process.

What should I pay attention to during the lifting and handling of the bonder?

SMT machines are high-tech products that are typically large and heavy. It is important to assess the customer’s workshop in advance to plan the lifting process and estimate costs accurately. Key site conditions to consider include the width of the factory gate and the height of the plant, which will help determine the appropriate vehicles, such as the size of lift trucks and wagons needed, as well as the height of the crane required. Additionally, because SMT machines have higher environmental requirements, it is necessary to use special air cushions during the lifting process to protect the workshop floor.

How to change the wire and load the SMT bonder equipment?

When SMT is producing new products or switching production lines, the foreman provides the material handler with the correct station list for the corresponding products. The material handler then loads the materials into the machine according to the station list. After loading, the materials are placed in the corresponding stations, and the team leader is notified for review. IPQC (In-Process Quality Control) will then verify the materials against the station list, material specifications, and material numbers. Once confirmed to be error-free, the technician is notified to proceed with the first piece production.

How to perform daily management and maintenance of the machine?

1. Filter Replacement: Develop a habit of regularly replacing the filter, typically on a monthly basis. 2. Reflective Cap and Plate: If poor recognition occurs, inspect or replace the reflective cap and plate. 3. Conveyor Belts: Always have a backup conveyor belt for replacement when necessary. 4. Cylinders, Bearings, and Synchronous Belts: Regularly check and replace these components as needed.

How much do you know about the operation and debugging methods of the bonder?

Once the new product sequence is prepared and optimized, the sequence and database must be adjusted on the bonder for production. This involves: 1. Adjusting parameters in the component database, 2. Setting placement coordinates for the components, 3. Defining coordinates for the datum point, and 4. Configuring the type and direction of the feeder.
