The charger, as one of the essential parts of the mobile phone, has brought an infinite business opportunity to the huge market demand.
Now that the overall profits of the mobile phone industry continue to fall, and even some of them are already selling at BOM costs, the only possible solution for chargers in this environment is to reducing management costs constantly, or to invest in automation equipment.
Mobile phone charger shell is one of the important component for mobile phone safety using, For aesthetic reasons, the current mobile phone charger is becoming smaller and smaller. With the decrease of volume, the heat dissipation in the process of charger use is considered by the manufacturers. Countries also have corresponding safety standards for charger products. European and American countries have clear regulations that the plastic materials around the needle must conform to UL94-V0 fire prevention grade.
Because the cost of plastic raw materials in accordance with this fire prevention grade is very high, in order to reduce the production cost, the current mobile phone charger producers basically use the secondary injection molding process. Secondary injection molding refers to the injection molding of the part that needs to be made of UL94-V0 grade material with the pin, and then the semi-finished product is put into the mold to complete the injection molding of the shell. This production process includes semi-finished parts-embedded-finished / sprue removal-finished phone charger placement and so on.
Alfa has developed a whole set of complete process automation solutions for charger industry. The scheme adopts mold embedded insert vibrating disk discharge system, full servo robot, we use the main arm to complete semi-finished product embedded and finished mobile phone charger shell removal, and sub-arm to complete sprue removal operation.
The product design and process application in this whole process solution is advanced, stable, reliable and consistent. In mass production, it can improve labor productivity, stabilize and improve product quality, improve working conditions, reduce production area, reduce production cost, shorten production cycle and ensure production balance, which has remarkable economic benefits. It can also provide a single machine solution for all kinds of customers; truly solve the industry problem, perfectly reduce the labor cost of its key stations, improve the profits for customers, and strive for greater living space.
