Automatic LED Repair System

I. Functions:
  1. Optical alignment, precise led beads placement, completely avoid misalignment;
  2. Breeze adjustment function, according to the size of the chip to adjust the wind speed, more  efficient repair, even tiny led beads will not be blown away;
  3. Laser positioning, place the motherboard in one step;
  4. With a led bead feeding device for a small volume of led beads be placed at a time, avoiding to fetch led beads one by one during the rework to increase the efficiency of the rework several times higher;
 5. The preheated temperature zone is covered with a fine layer of steel mesh to effectively prevent the led beads and other small devices from falling into the machine and damaging the machine.
  6. External temperature interface, easy to detect the temperature at any time, more accurate and reliable temperature control;
  7. Touch screen operation, the program is built-in in advance, can be skilled use without professional technical training, so that the chip rework becomes very simple;
  8. Both manual and automatic operation modes, debugging or batch rework are more convenient and simple;
  9. External USB interface for software updates and upgrades and various rework data imported into computer analysis and storage.
 
1. High-definition touch screen man-machine interface, integrated motion control card, and instant curve analysis function. Real-time display settings and measured temperature curve, can analyze and correct the curve.

  2. High-precision K-type thermocouple closed-loop control and automatic temperature compensation system. Accurately control the integrated motion control card to maintain the temperature deviation at ±1 degree. At the same time, the external temperature measurement interface can accurately detect the temperature and realize the actual measurement. Accurate analysis and calibration of temperature curves.

  3. Using stepping motion control system: stable, reliable, safe and efficient; using high-precision digital video alignment system, PCB board positioning using V groove and linear slide, so that the three axes of X, Y, Z can be fine-tuned or quick positioning, conveniently and accurately. Meet the different PCB board layout and different size PCB board positioning.

  4. The flexible and convenient removable universal fixtures can protect the PCB board, prevent PCB edge device damage and PCB distortion, and can adapt to the repair of various sizes BGA package.

  5. For the rework of LED bead, there is LED bead feeding device, the minimum can be repaired 1 * 1 LED lamp beads.

  6. With a variety of alloy nozzles, the nozzle can be rotated 360 degrees arbitrary positioning, easy to install and replace

  7. There are three independent temperature zones, three temperature zones can simultaneously perform multiple sets of multi-stage temperatures, to ensure that different temperature zones achieve the best welding results. Heating temperature, time, slope, cooling and vacuum can all be set on the man-machine interface.

  8. The upper and lower temperature zones can be set with 8 temperature control, mass storage temperature curve, can be called at any time according to different BGA. Curve analysis, setting and correction can also be performed on the touch screen. Three heating zones using an independent PID algorithm Control the heating process, increase the temperature evenly, and the temperature is more accurate;

  9. The use of high-power cross-flow fan to quickly cool the PCB board to prevent PCB board deformation. The process of placement, welding, disassembly are intelligent automation controlled;

  10. The joystick can be used to control the head to move up and down and enlarge and shrink the image. The operation is quick and easy.

  11. With voice-activated "early alarm" function. Voice-controlling the operator to make relevant preparations 5-10 seconds before disassembly and welding. After the upper and bottom hot air is stopped heating, the cooling system starts and automatically stop when the temperature drops to room temperature. Ensure that the machine will not age after heat up!

  12. CE certification, there is an emergency stop switch and accidental automatic power failure protection device.
