What are the characteristics of automatic sandblasting machine for selecting sandblasting treatment of notebook shell surface?

Characteristics of sandblasting processing of notebook shell by automatic sandblasting machine

First, the processing consistency is high, and the appearance color difference of the whole machine is unified.

The aluminum alloy and plastic casing of notebook have extremely high requirements on matte texture and uniformity of sand surface. The automatic sandblasting machine adopts mechanical reciprocating+rotating tooling to work at a uniform speed. The walking speed, spraying distance and air pressure of the sandblasting gun are stable and controllable, and the impact force of sand particles on each casing has no deviation. Borders, corners and dead corners of curved surfaces can be evenly covered, and the common problems of local whitening, sand leakage and over-hitting depression caused by manual sandblasting will not occur. The appearance texture of batch products is uniform, which meets the high standard of 3C digital appearance.

Second, adapt to the complex irregular surface of the notebook, without dead angle processing.

The notebook shell contains complex structures such as circular corners, stepped grooves, rotating shafts, LOGO sinks, etc. The automation equipment can be matched with three-axis/four-axis linkage motion mechanism, and the tooling can be rotated and turned over. The spray gun can move with the contour of the workpiece at multiple angles, and the spray angle can be automatically adjusted for deep grooves and narrow slits, which completely solves the defects of sand accumulation and uneven texture in manual sand blasting, and perfectly adapts to the sand blasting requirements of various special-shaped shells of ultra-thin books and game books.

Third, the pressure and sand quantity are intelligently controllable to protect the shell from deformation.

Notebook shells are mostly thin aluminum alloy and magnesium alloy sheets, which are easy to penetrate and sag; The automatic sandblasting machine is equipped with a pressure-stabilizing and pressure-regulating system, and the sand flow rate can be accurately adjusted, which can distinguish between two processes: coarse sand matte and fine sand soft fog. The thin-walled shell can be processed in a low-pressure fine mode, which can not only remove CNC knife lines and scratches, but also cause shell deformation and wall thickness thinning, and the flatness of finished products reaches the standard, thus reducing the rejection rate.

Four, closed dust-free operation, environmental protection and dust-free, clean and tidy workshop environment.

The whole machine is fully sealed sandblasting cabin, equipped with strong pulse dust removal and recovery system, and the sand material is recycled and filtered automatically, so that the dust does not overflow; It is different from the open manual sand blasting, which has large dust and dust attached to the shell, and the automatic equipment continuously removes dust. After processing, the shell has no floating dust and does not need to be wiped a lot twice. At the same time, it meets the requirements of environmental impact assessment in the workshop and reduces the damage of dust to equipment and personnel.

Fifth, the sand material is recycled, and the production cost is lower.

The equipment has its own automatic sorting and recycling device, which separates and filters broken sand and dust, and the intact abrasive can be recycled and used continuously, greatly reducing the consumption of emery and glass sand; Manual sandblasting has high loss of sand, mixed dust can not be recycled, and the cost of automatic sandblasting consumables can be significantly reduced under long-term mass production, which is suitable for mass continuous production of notebook shells.

Six, auto production line adaptation, saving labor and stable production capacity.

It can connect the loading and unloading manipulator and the conveying line, and realize the full-automatic process of loading the notebook shell-turning sandblasting-dust removal and blanking, with only one person on duty to patrol instead of 3-5 sandblasting operators; The equipment can operate continuously for 24 hours, and the production capacity is stable and controllable, which effectively solves the pain points of difficult recruitment and low labor efficiency in 3C industry, and is suitable for mass order production of notebook shells.

Seven, the process parameters can be stored, and the change can be quickly switched.

There are many groups of process programs built into the equipment, and the parameters such as air pressure, walking speed, spray gun distance and so on can be preset for different types of notebook shells and different sand surface effects (coarse matte, fine matte and semi-gloss), and the model can be switched with one button without repeated debugging; With special positioning fixture, the shell positioning is accurate, and the time of production change and debugging is greatly shortened, taking into account multi-model small batch and mass production.

Eight, the whole protection, shell surface without secondary scratches.

Automatic tooling adopts soft positioning fixture, and no hard metal contacts the shell; After sandblasting is completed, the dust in the cabin is automatically removed by wind, so as to avoid scratches and fingerprints caused by manual taking and wiping, ensure the integrity and cleanliness of the shell surface after sandblasting, and directly enter the next process of anodizing and spraying, thus reducing rework.

Nine, perfect safety protection, reduce production hidden dangers.

The equipment is equipped with safety door interlock, overload protection, dust removal and wind pressure alarm, and the cabin is sealed to prevent sand splashing from hurting people; Centralized dust collection and treatment can reduce the risk of dust explosion and occupational diseases, and meet the safety production standards of 3C electronic workshop.
