What Is The Magnetic Pick Up Type Screw Tightening Machine

Magnetic - type screw machine is an automatic equipment that uses electromagnetic principle to pick up screws and fasten them. The following is a detailed introduction to it:
Working principle:

The magnetic - type screw fastening machine generally adopts an electromagnetic device. When it runs, it moves above the feeder and picks up the screws through the magnetic force generated by the electromagnet. Then it moves above the hole position where the screws need to be fastened, goes deep into the hole position, and starts to fasten the screws. It directly uses the bit rod to pick up the screws without installing a suction nozzle like the adsorption - type or air - blowing - type screw machines. Therefore, it solves the problem that the suction nozzle cannot go deep into the deep hole with narrow space to fasten the screws, expands the application range, and improves the fastening production efficiency.
Scope of application:
Applicable screw materials: It is mainly applicable to magnetizable screws, generally screws made of iron materials.
Common screw specifications: It is usually applicable to screws with a specification of M2 - M4 and a length within 12mm.
Applicable products: Various irregular products such as deep - hole, curved - surface products. It can also be applicable to the situation of fastening multiple different screws at the same time, but the corresponding shapes of the screws and the bit heads need to be the same.
Performance characteristics:
Operation space and limit: It has a large operation space and a small Z - axis limit, which can flexibly adapt to the shape and position requirements of different products to a certain extent.
Running speed and accuracy: It has a fast running speed and high - repeat positioning accuracy, which can accurately fasten the screws to the specified position.
Maintenance and service life: It requires no maintenance and has a long service life, reducing the equipment maintenance cost and downtime.
Operational convenience: It is suitable for one - person - multiple - machines operation and has a simple structure, which reduces the labor cost and operation difficulty and has a high cost - performance ratio.
Detection function: It has the functions of detecting bad conditions such as screw slipping, missing fastening, and floating, which is helpful to ensure the assembly quality of products.
Efficiency: Generally, it takes 1.8 - 3 seconds per screw. The specific time will vary depending on the length of the screw fastening and the moving range of the arm.
