Considerations for repairing and maintaining vacuum suction cups

One of the vacuum equipment actuators is a vacuum suction cup, often known as a vacuum spreader. In general, employing vacuum suction cups to grab objects is a low-cost strategy. There are several types of vacuum suction cups. Rubber suction cups can withstand high temperatures, silicone rubber suction cups are ideal for gripping objects with rough surfaces, and polyurethane suction cups are extremely durable.

Furthermore, if oil resistance is necessary, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers might be explored for suction cup manufacturing. To minimize scratching the surface of the products, it is usually best to use suction cups made of NBR or silicone rubber with bellows suction cup material made of NBR, which has a high tearing force and is thus widely used in various vacuum suction holding equipment. So, what factors should we consider when employing vacuum suction cups? What are the things to keep in mind when using vacuum suction cups?

The choice of vacuum suction cup precautions:

1. The quality of the object to be transferred-determine the size and number of suction cups

2. the shape and surface state of the object to be transferred - the type of selected suction cups

3. Working environment (temperature)-select the material of the suction cup

4. The connection method-suction cup, connector, buffer connector

5. The height of the object to be moved

6. Buffer distance

Vacuum suction cup maintenance and repair methods: In the case of EOAT using vacuum suction cups (without clamping), it should be noted that the robot's movement speed cannot be too fast, as this will produce a tangential force on the suction cups and cause the products to fall off easily during the rapid twisting process. In some circumstances, a gripper can be employed to ensure that the products are delivered safely. If the product is likely to adhere to the mold, an air clamp can usually be fitted to remedy the problem. When the surface area of the product is too tiny or the product is too heavy to employ a vacuum chuck, a clamp can be used to remedy the problem.

If the product has a highly rigid appearance, the clamped element cannot be the exterior surface. A sensor circuit can be installed to solve this problem. After establishing that the gripper or suction cup has grabbed the product, the sensor sends a signal to the manipulator, allowing it to proceed with the next operation. If the robot's movement capabilities are limited and require a manual twist or tilt to release the product or move the product and EOAT out of the molding region, a specific cylinder that can move the EOAT without relying on the robot can be installed to solve this problem.

The end tool for in-mold labeling does three things: it picks up the logo, inserts it into a small spot, and finally fixes it in the mold. In comparison to a static labeling device, the EOAT's final operation is the removal of the labeled plastic bottle from the mold. while molding automotive parts, special care should be used while working with Class A surfaces. The vacuum suction cups are included in the Fuyu Automation vacuum suction cup selection, and their use must be prevented to avoid scratches on their surfaces. In this instance, try placing an acetal clamp on the EOAT to successfully avoid scratching the product's surface.
