Vacuum pads F&Q

Vacuum pads application?

Also named Suction cups, Vaccum cups and vacuum grippers,  It use vacuum principle to absorb the workpiece in order to achieve the purpose of moving the workpiece. It used to move the objects or grip the products. 

Selecting the type of vacuum pads must consider the operating temperature, stroke, speed, pressure, in order to achieve the most appropriate results.

Vacuum pads feature?

  1. EASY LOSS : Most vacuum pads types made of rubber. It contacts the objects directly, therefore, it easy to wear and loss quickly.
  2. EASY USE : No matter what material object need to be sucked, only if it can seal and can be used.
  3. WITHOUT POLLUTION : There are no light, heat, electromagnetic and other pollution.
  4. CANNOT HURT THE WORKPIECE : It is made of rubber material. It will not cause any harm to the workpiece when gripping or laying down the workpiece , but not for hook spreader and cable type spreader.

How to select Vacuum pads?

  1. The adsorption area of workpiece determine the pad diameter and number of pads. If the workpiece is big, taking into consideration the balance of the workpiece, idendiry the adsorption positioning and distribute the pads reasonable.
  2. Selecting the type of suction pads based on the the transferred object and surface condition such like permeability, anti-static, resistance to copper ions, absorption shape, absorption area, flatness…… and so on.
  3. According to different temperature to select different pad material. Recommended the use of silicone (SI) material or polyurethane (PU) material in high temperature environment  ; using natural rubber (NR) material in low temperature environment.
  4. Connection - vacuum pad, connector, connector with buffer.
  5. To transfer from different level - horizontal lifting or vertical lifting.
  6. Stroke Dimensions .

What is ESD vacuum pad?

Electrostatic causes : friction, peel, induction……and etc.
The substance is charged by loss or gain of electrons.

What is ESD discriminate three levels as below?

ESD discriminate three levels as below:

  1. ANTI-STATIC :
  2. SURFACE ELECTRIC RESISTANCE 109~1012

  3. Electrostatic dissipative :
  4. SURFACE ELECTRIC RESISTANCE 106 ~ 109Ω

  5. Conductive :
  6. SURFACE ELECTRIC RESISTANCE 104~106Ω
    DIN IEC 1340-4-1 request antistatic material level is 106~109Ω

Why do I need anti-static dissipative grade material?

People walking or friction, is the main source of static electricity. Static electricity build-up can cause electric shock or damage to the precision equipment.

EX : Most moden offices use the central air-conditioning, which use all day will make the air more dry and will cause static electricity easy to produce, gathered and not easy to dissipate.

Why do I need conductive grade material?

In the high-precision space, such as wafer production line, operation room, ammunition depot……and etc. The static electricity can not be gathered. It must be discharge via static-conducting agent in order to avoid danger

EX : Doctors need to monitor a variety of index on precision instruments. If the computer and the instrument are interfered due to static and make the reading is not correct. It may lead to a doctor misjudgment and results in irreparable error.

What is conclusion of ESD vacuum pad?

Electro Static dissipative : Suitable for offices, schools, hospitals, public indoor places, factory offices, processing factory.

Conductive : Suitable for surgery room, ammunition depots, IC equipment, wafer production lines, and other precision plant.

CNL provides two level anti-static materials?

  • Conductive :

    SURFACE ELECTRIC RESISTANCE 104~106Ω

  • Electro Static dissipative :

    SURFACE ELECTRIC RESISTANCE106~109Ω

Two kinds of material can be selected?

  1. Silicon
  2. NBR

CNL will use a professional surface resistance measuring instruments to test materials and finished products during the manufacture and QC to sure to meet the above two levels. 

These antistatic materials are widely used in vacuum suction cups in order to prevent the production line free from the static electricity and cause product damage.

Static Electricity Is The Killer Of The Electronics Industry

Electrostatic causes in many ways, such as contact, friction, and so on.

The process can be summarized as: contact → charge → transfer → charge layer formation → charge separation

Equipment or human body cause the electronics up to tens of thousands of volts or even hundreds of thousands of volts, even under normal operating conditions are often caused hundreds to thousands of volts.

The human body due to its own action and contact with other objects - separation, friction or induction and other factors, can bring thousand volts or even tens of thousands of volts of static electricity.

Static electricity is the result of positive and negative charge lose balance.

It is a kind of performance in the object with electric energy. The featuress are high potential, low power, small current and short acting time.

It differentiates hard breakdown and soft breakdown.

  1. Hard breakdown causes dielectric breakdown, burnout or permanent failure in one-time.
  2. Soft breakdown is caused by the performance degradation of the device or parameter indicator.
