What to Be Aware of During the Use of a Vacuum Suction Cup ?

Precautions for the use of vacuum suction cups

  • The digital pressure switch in the control box displays the vacuum degree. The red indicator light stops, and the green indicator light starts. The next switch is divided into automatic and manual modes. In normal use, just switch to automatic mode. During processing, the pull valve switch on the vacuum suction cup can control it directly.

  • During vacuum suction cup processing, the white silicone strip is sealed in the suction cup groove. Generally, the circumferential size is smaller than the workpiece path. The workpiece is placed on it, and the silicone strip can be reused.

  • The automatic pressure-maintaining vacuum suction cup has multiple suction holes on the working surface, which can be opened several holes at the same time, or one of them can be selected for use, and the others can be blocked.

  • When the auto-pressure vacuum suction cup inhales a large amount of cutting fluid during processing, there is a drainage hole at the bottom of the air tank in the control box, which can discharge the cutting fluid inside. The connected filter can also filter the chips that enter the suction cup and discharge them through the suction air hole.

  • When the vacuum suction cup is not used for a long time, please turn off the power on the control box and apply rust-proof oil on the surface of the suction cup.

Precautions during the use of suction vacuum cups

Suction vacuum cups are also called vacuum lifters. Generally, using vacuum suction cups to grab products is the cheapest method. Types of vacuum suction cups: rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grabbing rough surface products, and polyurethane suction cups are very durable.

In addition, in actual production, if the suction cup requires oil resistance, polyurethane, nitrile rubber, or polymers containing vinyl can be considered to make the suction cup.

Generally, to avoid surface scratching of the product, it is best to choose a corrugated suction cup made of nitrile rubber or silicone rubber. When using vacuum suction cup (without clamping), the robot arm should not move too fast, otherwise shear force will be generated on the suction cup, making the product easy to fall off during rapid rotation.

In some cases, clips can be used to ensure the safe delivery of products. Considering that the product may adhere to the mold, vacuum suction cups are usually equipped with an air clip to solve this problem.

Even in very special environments, vacuum suction cups have a wide range of applications. However, special maintenance is required for vacuum suction cups in special environments, and some issues should be noted during use.

  • For low-temperature environments

When using vacuum suction cups below 5°C, measures such as air drying should be taken to prevent condensation, water, and compressed air from solidifying or freezing.

  • Shock and vibration

The impact of electromagnetic pulses on vacuum components should be below 150 kPa, and the vibration should be below 40 kPa. If it exceeds this value, it may cause an operation error.

  • The wiring of the vacuum suction cup pressure sensor should be far away from high-voltage power sources, high-voltage wires, and power lines

It constituted interference to the high-voltage power supply. Otherwise, it will cause non-action or failure.
