automatic COB laser cleaning machine

Equipment introduction

Spacious Division is engaged in laser devices, laser device, motion control, machine vision technology development, application and service of high-tech enterprises. For many years, we have made great progress in the field of motion control and machine vision based on laser technology, motion control technology, image and data acquisition and processing technology, PLC and other special motion controller. The technology of motion control, field bus, machine vision and so on.

PCB before solid crystal bonding, Goldfinger would have some subtle oil or dust, which will lead bonding of bad contact, make products scrap rate high, the rejection is the product, the cause is the economic loss. So in the state before the PCB gold finger on the oil or dust cleaning, which appeared on the artificial board and the machinery to wipe the board, artificial board and mechanical wipe board efficiency is low, the effect is not good, dust big, will produce mechanical friction, the requirements of personnel, work labor, quality is not stable, part of the product will make skin allergies, in order to solve these problems we developed a fully automatic laser.

Laser cleaning machine with long life laser, electro optical conversion efficiency is high, the use of air cooling, small size, output beam quality, high reliability.

Working mode: laser output specific wavelength laser, and ultra high speed scanning vibrating mirror so that the laser in accordance with the set of tracks on the need to clean the material to do the cleaning, gold finger on the oil or dust by laser irradiation from evaporation to achieve the cleaning function; the circuit board is stronger, better contact, bonding effect is more than 10 times the speed of the traditional manual brush plate, greatly improving the work efficiency.

The latest development of COB fully automatic vision on the board equipment, based on our fully independent intellectual property rights of motion control and machine vision software technology, the previous equipment in many places, many customers, different application occasions based on the actual experience to do a number of improvements. Cob automatic visual contraposition wiping machine in addition to maintaining the "direct discharge without fixture", "PCB 360 degrees of freedom put", "bad board automatic sense tagging" the original function of the "rub board optimal path" outside, also increased the light curtain sensor to prevent in advance to take in other functions.

At the same time, the efficiency of the equipment and the structure of the design has also greatly improved, still maintain the current domestic COB brush plate industry technology leader. The application of this device greatly reduces the use and dependence of the COB board in the process of cleaning board, and the operation is simple, which greatly improves the production efficiency and yield. Greatly improve the automation level and production efficiency of the COB industry, has been unanimously approved by the user.

Comparison of three kinds of rubbing plates

One, the chemical reagent to wash;
Two, manually erased by manual;
Three, the automatic device to erase the machine;

Comparison of three kinds of method for cleaning plate and the advantages of the machine:

1 the use of chemical reagent cleaning. This method has a certain pollution to the environment, but it can not completely remove the water in the PCB matrix and the hidden trouble of the products after the bonding.

2 the use of rubber block or fiber stick division. This method has the disadvantages of large workers, enthusiasm is not high, the production efficiency, especially after the clean PCB SMT, clean quality is very unstable, and requires a lot of manpower.

3 laser output specific wavelength of laser, and then by ultra high speed scanning vibrating mirror to set the track on the need to clean the material to do the cleaning, gold finger on the oil or dust by the laser irradiation from evaporation to achieve the cleaning function; the circuit board is more conductive, better contact, bonding effect is better, the speed is more than 10 times the speed of the traditional manual.

The characteristics of automatic visual alignment COB laser cleaning machine

1.winXP Chinese interface, easy to learn and easy to understand;
2 accurate CCD image visual instruction to achieve fast programming;
3 products are arbitrarily placed, the automatic positioning of the visual identification of continuous wipe;
4 high speed, no noise, no contact with the laser beam, the effect is better;
5 laser energy stability;
6 full automatic identification of bad boards, (bad plate automatically not rub);
7 to prevent incorrect operation of PCB board damage, (no bad rate);
8 circular table, suitable for different parts of the 360 degree automatic positioning.
9 the power consumption of the whole machine is low, the power consumption can be 24 hours continuously.
10 speed, the fastest speed per hour up to 8000.
