The end tool for in-mold labeling can complete three actions: In a limited space, EOAT first picks up and inserts the trademark, and then fixes the trademark in the mold. This operation reduces the size of the unit compared to static labeling units. The final action of EOAT is to remove the branded plastic bottle from the mold. Generally, when injection molding automotive parts, extreme caution should be exercised with products with Class A surfaces. In order to avoid scratches on its surface, the use of vacuum suction cups must be absolutely prohibited. At this time, you can consider installing a clamp made of acetal on the EOAT, which can effectively avoid scratching the surface of the product. So, how to use EOAT in complex machining and molding processes? To illustrate this problem, let’s take an example of over-injection molding using nylon and rubber. In this example, a versatile end-of-arm tool (EOAT) is utilized to keep the operator at hand.
As an important branch of industrial robots - manipulators in
1. The quality of the objects being moved – determines the size and number of suction cups
2. The objects being moved The shape and surface condition of the object – select the type of suction cup
3. Working environment (temperature) – select the material of the suction cup
4. Connection method – suction cup, joint, buffer connector
5. The height of the moved object
6. Buffer distance
A British amateur inventor used two vacuum cleaners as power to develop a vacuum cleaner. This is a vacuum suction cup. Each hand holds a giant suction plate connected to the vacuum cleaner backpack on the back. It can crawl on the wall, just like Spider-Man, which is very enjoyable.
The inventor is Stansfield. He bought two 1,500-watt vacuum cleaners in the supermarket. After removing the casings, he installed the two machines on a back plate. It is carried like a bag on the back. The long suction throats of the two shelling vacuum cleaners are each connected to two vacuum suction plates. The suction plates are sealed with rubber to ensure strong suction power. Stansfield hung the vacuum engine backpack on his back, then held a vacuum suction board in each hand, while his feet stepped on the long strap hanging from the suction cup.
When you start the vacuum cleaner, you can use the air extraction principle to walk on the wall with the two suction boards. When pushing the suction boards upward, take one step to match, so it is like climbing a wall. , crawling up step by step.
He used this vacuum suction cup to successfully climb up the 30-foot-high school exterior wall step by step in front of a group of spectators, straight to the rooftop. Spectators on the street were dazzled.
Stansfield is currently a presenter on BBC One and previously produced special effects for the science fiction film "Lost in Space". When EOAT uses a vacuum suction cup (without clamp), 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, making the product easily fall during rapid twisting. . In some cases, a clamp may be used to ensure safe delivery of the product. Considering that the product may stick 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 suction cup, this problem can also be solved by using a clamp.
If the appearance of the product is very strict, then the clamped part cannot be the outer surface. To solve this problem, a sensing circuit can be installed. After confirming that the clamp or suction cup has firmly grasped the product, the sensor will send a signal to the manipulator so that it can proceed with the next operation. In cases where the manipulator has limited movement capabilities and requires manual twisting or tilting to demould the product or move the product and EOAT out of the molding area, a special cylinder can be added that can move the EOAT independently without relying on the manipulator's operation. One problem has been improved.
The end tool for in-mold labeling can complete three actions: In a limited space, EOAT first picks up and inserts the label, and then fixes the label in the mold. This operation reduces the size of the unit compared to static labeling units.
The final action of EOAT is to remove the branded plastic bottle from the mold. Generally, when injection molding automotive parts, extreme caution should be exercised with products with Class A surfaces. Vacuum suction cups are included in the quick and easy automatic selection. In order to avoid scratches on their surfaces, the use of vacuum suction cups must be absolutely prohibited. At this time, you can consider installing a clamp made of acetal on the EOAT, which can effectively avoid scratching the surface of the product.
