Vacuum suction cup maintenance and maintenance precautions, how much do you know?

Vacuum suction cups, also known as vacuum spreaders, are one of the vacuum actuators. In general, the use of vacuum chucks to grab articles is one of the cheapest methods. Vacuum chucks are available in a variety of sizes. The suction cups made of rubber can be operated at high temperatures. Suction cups made of silicone rubber are ideal for gripping rough surfaces; suction cups made of polyurethane are durable.

In addition, in actual production, if the suction cup is required to have oil resistance, it is conceivable to use a material such as polyurethane, nitrile rubber or vinyl-containing polymer to manufacture the suction cup.Generally, in order to avoid scratching the surface of the product, it is preferable to select a suction cup with a bellows made of nitrile rubber or silicone rubber, which is made of nitrile rubber and has a large breaking force, so it is widely used. Various vacuum holding devices. So, what should we pay attention to when using vacuum chucks?

First, choose the vacuum sucker precautions

1. The quality of the object being transported – the size and number of the suction cup 
, the shape and surface condition of the object being transported – the type of suction cup selected 
, the working environment (temperature) – the material of the suction cup 
4, the connection method – the suction cup, the joint , buffer connector 
5, the height of the object being transported 
6, buffer distance

Second, vacuum suction cup maintenance and repair methods

In the case of EOAT using a vacuum chuck (without clamp), it should be noted that the movement speed of the robot should not be too high, otherwise a shear force will be generated on the suction cup, which will make the product fall easily during the rapid twisting process. . In some cases, a clamp can be used to ensure safe delivery of the product. In view of the possibility that the product may adhere to the mold, a gas clamp can usually be installed to solve the problem. When the surface area of the product is too small or the product is too heavy to use the vacuum chuck, the same problem can be solved by using a clamp.

If the product is very strict in appearance, the clamped portion cannot be the outer surface. To solve this problem, a sensing circuit can be installed. After confirming that the clamp or suction cup has gripped the product, the sensor sends a signal to the robot to enable it to proceed to the next step. In the case where the manipulator has limited athletic ability and needs to be manually twisted or tilted to demold the product or remove the product and EOAT from the molding zone, a special cylinder capable of moving the EOAT alone without relying on the robot can be added, thereby making this possible. A problem has been improved.

The end tool for in-mold labeling can perform three actions: in a limited space, EOAT picks up and inserts the mark and then fixes the mark in the mold. This operation can reduce the size of the device compared to static labeling devices. The next action of EOAT's z* is to remove the branded plastic bottle from the mold. In general, care must be taken in the handling of Class A surface products when injecting automotive parts.Vacuum suction cups are easy to use and automatic selection. In order to avoid scratches on the surface, vacuum suction cups must be absolutely prohibited. At this time, it is conceivable to install a clamp made of acetal on the EOAT to effectively avoid scratching the surface of the article.
