Automatic soldering machine

Automatic soldering machine is a wave soldering reflow position after the station, the main role is to weld the original component which cannot over the furnace, its applications and industries is widely. In principle, the use of artificial solder stations as well as use automatic soldering machine. Due to product differences, there will be differences in efficiency and clamping mode, its main supply to the electronics manufacturer, the main application industry, home appliances, toys, communications, medical equipment and many other industries.

Automatic soldering machine’s quality is our primary concern. But inevitably there will be some minor problems, such as leakage welding, stacking tin, solder joints and other issues. How to made these problem happened? Is there any solution to solved the problems? With these questions, our engineer evaluate the problems. Weld generally refers to the welding process can also look at the solder joints, in fact, when welding or fishing through the tin is not enough. The main reason for the soldering problem is the soldering iron tip on the residence time is not enough or the temperature is too low caused. So we only extend the tip of the residence time or elevated temperature, then can be resolved. Sinrad Technology Co., Ltd will research and develop more innovative machine in near future.

The Application of Laser Technology in Mobile Phone

Mobile phone is popular in market, and now people in daily life essential personal items, instant messaging, camera, use the APP, play games and even pay for the purchase, all inseparable from smart phones. A small cell phone, even with so many features, it makes people have to wonder!

As you know, "laser" as an advanced processing technology, in the mobile phone manufacturing process, played a pivotal role.

Laser Marking

Laser marking is the use of high-energy laser irradiation of the workpiece on the local exposure, the surface material vaporization or color change of the chemical reaction, leaving a permanent mark of a marking method, with high precision, fast, clear mark And so on. Mobile phone laser marking this permanent marking method, can improve the anti-counterfeiting ability, but also increase the added value, the product looks higher grade, more brand.

In the phone we can find the shadow of laser marking, such as: Logo marking, cell phone keys, cell phone casing, cell phone batteries, mobile phone accessories, marking, etc., even in your invisible cell phone, there are parts laser .

laser cutting

Laser cutting can be metal or non-metallic components such as small parts for precision cutting or micro-hole processing, cutting with high precision, speed, heat and small advantages. Mobile phone common laser cutting technology: sapphire glass mobile phone screen laser cutting, lens protection lens laser cutting, mobile phone Home key laser cutting, FPC flexible circuit board laser cutting, mobile phone handset network laser drilling and so on.

Laser welding

Laser welding is the use of high-energy-density laser beam as a heat source, the material surface melting and then solidified into a whole. Heat affected zone size, weld aesthetics, welding efficiency, is an important indicator of good or bad welding process. HG laser precision laser welding machine for the processing of parts, precision instruments and other small parts, high precision welding, integrated, split and other welding supporting the choice of workstations.

Problems in Soldering Robot Application and Solution

Share from OFweek robot network

(1) There is welding bias problem:

It may be that the welding position is incorrect or there is a problem with the welding torch. At this time, to consider the TCP (welding torch center point) is accurate, and be adjusted. If this happens frequently check the zero position of each axis of the robot and recalibrate the zero to reset it.

(2) Undercut problem:

May be improper selection of welding parameters, welding torch angle or welding gun position is not right, need to be adjusted appropriately.

(3) The emergence of stomatal problems:

May be poor gas protection, the workpiece is too thick or not enough protective gas drying, the corresponding adjustment can be handled.

(4) Too much splash problem:

The improper selection of welding parameters, the reason of gas components or the extension length of welding wire is too long. The welding power can be adjusted by changing the welding parameters, adjusting the proportion of gas mixture and adjusting the relative position of welding torch and workpiece.

(5) The end of the weld after cooling to form a crater problem:

Programmable in the work step to add the function of buried crater, you can fill it.

Automatic Soldering Machine Application

According to IFR (International Robot Federation) data show that the prospects for the world industrial robot market is bright, China will become the world's industrial robot demand in the next few years, the first big demand country. The electronics industry has become the second largest industrial robot application after automotive components, accounting 30% demand for industrial robots in the overall level of. From the current development of China's electronics industry point of view, industrial robots are mainly used in handheld electronic devices, household appliances, spare parts and other fields. Robots are subdivided into applications such as automatic soldering robots, mobile printing robots, automatic screwing robots, automatic cutting robots, automatic oiling robots, and automatic dispensing robots, and automated solder robots is particularly important in all of them.

Soldering technology in the development of modern industry plays an important role in related technology, related to materials, information, machinery, electronics and other disciplines. At present, the automated soldering equipment in a wide range of applications on the basis of a technical breakthrough and development of the end of the traditional human solder production model, the production efficiency has been greatly improved. Automatic soldering equipment development and application is an inevitable trend, and has penetrated into the electronics-related industries. Soldering equipment in the electronics industry as shown below.

 

Automatic soldering equipment, the operation of stability, and its core strengths is the automation and intelligent mode of operation to ensure consistency of welding products, flexible design to achieve a variety of product operations; In addition it has a high production efficiency, Put material links need artificial support.

Solder application technology development, has also expanded its application areas, is currently widely used in automotive electronics, home appliances, parts, LCD, circuit boards and other advanced manufacturing industries. Automation soldering technology has become the mainstream of the development trend of related industries, automated soldering equipment in the following occasions the application has a pivotal role.

(1) In the aerospace, defense, aviation, automotive and communications equipment and other industries, in order to ensure the welding accuracy and reliability of solder joints in different extreme conditions, automatic welding technology is the best choice.

(2) Devices that are not sensitive to temperature and can not pass reflow and wave soldering, such as connectors, DIP packages, shields, sensors, transformers, cables, cables, horns and motors.

(3) mixed circuit boards, rigid-flex combination board, soft and hard combination plate, with three-dimensional structure or stacked design of the workpiece limits the wave soldering and reflow soldering and other production equipment.

(4) small batch production or trial production, will not use complex production methods or expensive large-scale equipment.

With the rise of raw materials, rising labor costs and homogenization of competition to the industry with many variables and difficulties, automatic soldering machine industry has drawn greater attention in recent years, its growth potential is huge. So we have to be ready to seize the market demand, efforts to expand the advantages of the products and applications, automatic soldering machine for the entire industry to bring more successful cases and proven solutions.
