What Is a Vacuum Actuator?

Vacuum suction cup, also known as vacuum spreader, is one of the vacuum equipment actuators. In general, vacuum suction cups are the cheapest way to grab an article. There are various types of vacuum chucks. Suction cups made of rubber can be operated at high temperatures. Suction cups made of silicone rubber are very suitable for grasping products with rough surfaces. Suction cups made of polyurethane are very durable. In addition, if the suction cup is required to have oil resistance in actual production, materials such as polyurethane, nitrile rubber, or a vinyl-containing polymer may be considered for manufacturing the suction cup. Generally, in order to avoid the surface of the product being scratched, it is best to choose a suction cup material with a corrugated tube made of nitrile rubber or silicone rubber, which is made of nitrile rubber and has a large breaking force, so it is widely used in Various vacuum holding equipment.

Use of vacuum chuck

The end tool for in-mold labeling can perform three actions: In a limited space, EOAT first picks and inserts the trademark, and then fixes the trademark in the mold. Compared to a static labeling device, this operation can reduce the size of the device. EOAT's final action is to remove the labeled plastic bottle from the mold. In general, care must be taken when handling automotive parts with Class A surface finish when injecting automotive parts. To avoid scratches on the surface, the use of vacuum chucks must be absolutely prohibited. At this time, you can consider installing a clamp made of acetal on EOAT, which can effectively avoid scratching the surface of the product. So, how to use EOAT for complex processing? To illustrate this problem, we will give an example of overmolding with nylon and rubber. In this example, a multifunctional robotic end-of-arm tool (EOAT) is used by the operator.

As an important branch of industrial robots--

Selection of vacuum chuck

First, the quality of the transferred object-determine the size and number of suction cups

Second, the shape and surface state of the transferred object-the type of suction cup selected

Third, the working environment (temperature)-choose the material of the suction cup

Fourth, the connection method-suction cup, joint, buffer connector

Five, the height of the transferred object

Buffer distance

Vacuum suction cup application

An amateur inventor in the United Kingdom, using two vacuum cleaners as a power source, developed a vacuum suction cup, each holding a giant suction plate connected to the back of the vacuum cleaner's backpack, which can crawl on the wall, like Spiderman Very enjoyable.

The inventor was Stansfield. He bought two 1500-watt vacuum cleaners in the supermarket. After removing the casing, he mounted the two machines on a back plate and carried it like a backpack on the back.

British man invented vacuum suction cup to transform Spider-Man wall climbing

The long suction throats of the two shell vacuum cleaners are each connected to two vacuum suction plates, and the suction plates are sealed with rubber to ensure extra strong suction. Stansfield hung the vacuum engine rucksack in his back, then held a vacuum suction plate in each hand, and stepped his feet on a long belt hanging from the suction cup.

When you start the vacuum cleaner, you can use the suction principle to move the wall by holding two suction plates. When you push the suction plate upward, you step on one step to cooperate, so it is like climbing a wall and crawling up step by step.

Using this vacuum suction cup, he successfully climbed the 30-foot-high school exterior wall step by step in front of a group of audiences and straight up to the rooftop. The street audience was dazzled.

Stansfield is currently a host of a BBC show and has previously produced special effects for the science fiction film Lost in Space.

Vacuum Sucker Maintenance

In the case of EOAT using a vacuum suction cup (without clamps), it should be noted that the moving speed of the manipulator cannot be too high, otherwise a shear force will be generated on the suction cup, so that the product will easily fall off during the rapid twist . In some cases, a clamp can be used to ensure the safe transportation of the product. Considering that the product may adhere to the mold, an air clamp can usually be installed to solve this problem. When the surface area of the product is too small or the product is too heavy to use a vacuum chuck, this problem can also be solved by using clamps.

If the product has strict requirements on appearance, the part to be clamped cannot be the outer surface. To solve this problem, a sensing circuit can be installed. After confirming that the clamp or suction cup has held the product firmly, the sensor will send a signal to the robot to enable it to perform the next operation. If the robot has limited movement ability and requires manual twisting or tilting to demould the product or move the product and EOAT out of the molding area, a special cylinder that can move the EOAT independently without relying on the operation of the robot can be added to make One problem was improved.
