Working principle, characteristics and application of empty suction cup (vacuum spreader)

- Aug 02, 2019-

The vacuum spreader consists of a vacuum handling system, a vacuum automatic pick and place system, a vacuum clamp and all other vacuum handling accessories. It uses the vacuum principle to absorb objects and thus balance the gravity of the object. The operator can easily carry out the handling, turning, assembly and other processes of the object without substantially grasping the gravity of the object. The vacuum spreader is simple to operate, labor-saving, efficient and safe. Therefore, it is widely used in industries where automobiles, home appliances, packaging, etc. are frequently transported!


First, the working principle of vacuum spreader


A vacuum is generated by evacuating the air in the suction cup, and an atmospheric pressure of 1 kg/cm 2 (950 to 1050 mbars) is withdrawn. Therefore, the suction cup was pressed at a pressure of 1 kg/cm 2 . We can get a pressure of 10000kg on a 1m2 vacuum chuck. This physical fact leads to a very efficient handling system.


Second, the main advantages of using vacuum spreaders


1. Fast operation


The vacuum energy is stored in the vacuum accumulator. Within one second, it can be transferred to the suction cup for instant suction. Within two seconds, the vacuum in the suction cup can be returned to an atmospheric pressure for immediate release.


2. Safe use


The vacuum of the spreader usually comes from the accumulator. The energy reserve can be kept for several hours in the event of a power failure of the vacuum pump. The degree of vacuum is controllable. The sensor can show the system in case of a leak and the release of the load. As long as there is a proper vacuum in the suction cup, the load will not fall. Just a physical rule.


3. Safe adsorption, no damage to the surface of the material


The vacuum spreader mainly relies on the vacuum source to generate vacuum in the air inside the suction cup. The general suction cup is made of silica gel, natural rubber, nitrile rubber, etc., and can carry out the damage-free handling or loading of materials such as plates and glass.


4. Easy to operate


Since the operation of the vacuum spreader is on the top, it becomes easier to grab, lower, and release. This is one of the main advantages of using a vacuum spreader to carry things.


5. Saving time and effort


The use of vacuum spreaders can reduce the number of employees in the storage area. Suction and release can be done with just one person: the driving operator. In any case, it is possible and necessary to reduce the number of workers engaged in hard and dangerous work.


Since the handling of the vacuum device is very fast, cost savings are present in the speed. Our vacuum handling system does not leave marks on the product, so it can handle materials that require careful handling.


Third, the general application of vacuum spreaders


Vacuum spreaders are used in:


1. Plate handling of iron plates, aluminum plates, steel plates, slate, etc. and laser cutting machine loading.


2. Handling and loading of coils such as iron coils, steel coils and aluminum coils


3. Handling and loading of concrete prefabricated parts


4. Handling and loading of pipes such as iron pipes and steel pipes


5. Handling of various types of glass.


6. Applicable to all kinds of material handling with flat surface and regular shape
