How to ensure the safe use of electric suction cups?


Theoretical safe suction means that when the electric sucker is not aging and hardened, the electric sucker will not be damaged or cracked, the surface of the electric sucker is clean, the surface of the board is of good quality, and the lip of the electric sucker is more closely attached to the surface of the board. In the case of less air leakage, the vacuum degree can reach more than 60%. How to ensure the safe use of electric suction cups?

Therefore, to ensureElectric suction cupPlease pay attention to the safe use of the system:

(1) Make sure to clean and inspect the lip surface of the electric suction cup (on the side attached to the board) regularly, and check the electric suction cup regularly for scratches, cracks and aging. If so, replace with a new electric suction cup immediately. I have seen that the electric suction cups used by many companies are unsafe, making people worry about safety accidents.

(2) When the surface of the steel plate is rusty and uneven, the safety factor should be enlarged, otherwise it may not be well absorbed. In response to this situation, Qi Ren innovatively designed a set of quick hooks (diamond hooks). The system is symmetrically integrated at both ends of the beam and is suitable for the following two situations:

-During the feeding process, if there is a sudden power failure and the diamond hook is used, the steel plate will not fall off when you call again.

-When the steel plate is rusty or exceeds 10 mm, lift it up with an electric suction cup, and then put on a diamond hook to ensure safety and safety.

The influence of vacuum power supply on vacuum pressure:

Electric suction cup feeding is a manual auxiliary feeding method, it is necessary to ensure the safety of personnel.

The vacuum of the vacuum generator is lower than that of the vacuum pump, so it is safer to use the vacuum pump as the vacuum power source. Professional gas supply system companies do not use vacuum generators. Another factor is that due to the requirements for high-pressure gas, some factories have insufficient gas sources and inconvenient gas pipe layout.

There are also two types of vacuum pumps, one is three-phase electricity, which needs to be connected from the workshop electrical box to the control box of the electric suction cup system.

One is to use a weak current vacuum pump as the vacuum power supply. If the customer drives too high on the spot and it is inconvenient to get electricity, please use this pump, use a 12V battery for power supply, and charge it regularly.

Sheet metal suspension requirements of electric suction cup system:

Overhang is the distance between the edge of the board and the edge of the closer electric suction cup.

When the amount of drape is large, the board sags seriously, and the electric suction cup cannot absorb it. 1mm piece, safety hanging 500 mm. Taking into account the amount of overhang, for steel plates of different sizes, the length of the main beam, the number of electric suction cups and the distance between electric suction cups must be specially designed.
