Best solution for automated and semi-automatic solar photovoltaic industry

Not all vacuum fixtures are suitable for the process steps of producing photovoltaic modules. In the face of such thin and fragile products as chips, it is difficult for traditional fixtures to break through the barrier of how to take action on them in a light and safe manner without damaging objects. At this industrial exposition, Schmitz Company brought the latest technology to solve this problem at its new product conference.

On the booth of Schmitz, there were many large vacuum lifting devices on display, but they could not see the relevant introduction of their “fist product” – originally, they kept this “secret weapon” at the new product conference held at 4:30 p.m. At this press conference, Schmitz introduced the excellence of the product to everyone with rich videos and concise explanations.

SWG, a special fixture for solar photovoltaic industry, sounds a bit mysterious, but actually it refers to the special fixture for automatic handling of wafers and solar cells using vacuum technology. This fixture is not simple. It can safely and accurately absorb, transport, locate and release fragile chips that are as thin as paper. It has the following six characteristics:

1. Large contact area. SWG clamps are divided into 2 specifications, namely 5 inches and 6 inches. It has a large contact surface when gripping the wafer, which can ensure that the maximum gripping force is evenly distributed on the entire wafer surface, so as not to crack it.

2. High speed and high precision. As the saying goes, “Slow work produces meticulous work”, but in today’s flow production, efficiency cannot be ignored. Although SWG is also engaged in “delicate work”, it operates at a high speed of 1 piece per second, which is amazing. Not only that, it does not produce displacement during transportation, which is really fast and accurate.

3. Low gas consumption. Compared with Bernoulli principle fixture, SWG has a lower operating cost and realizes energy conservation and environmental protection.

4. Low vacuum. 60% vacuum is the critical value of SWG, and its large contact surface also ensures the minimum torque and the lowest risk of fracture.

5. High suction. SWG’s strong adsorption force firmly “sticks” the chip to its surface, even if it is damaged or deformed, it can not be “thrown off”. This makes the production process safer and more stable without residues.

6. Modular design. The fixture surfaces, sensors and optional damping units made of different materials can meet the different demands of different products on the fixtures and make their installation more convenient. In addition, the small holes on its surface can also be additionally installed with sensors and detection devices, so that manufacturers can detect products while carrying them, killing two birds with one stone.

As a world leader in vacuum technology, Schmitz not only introduced SWG, but also brought new devices of other vacuum fixture systems, such as metal processing vacuum fixtures, various types of lifting equipment, rail systems, etc. It shows us the technological innovation and infinite possibilities in the handling industry.
