The simple structure is: 1 motor, 1 multi-shaft output reducer, n universal joints, n connecting rods, n quick clamp couplings and n screwdriver heads from top to bottom.
The more complex structure is basically the same as above, but generally the whole set of things is mounted on a 3-axis or 2-axis coordinate manipulator (usually with an air cylinder or oil cylinder for both axes). The control system mostly adopts servo system, which is convenient for multi-specification and small batch production.
Power is generally single-axis electric and pneumatic, multi-axis pure electric, electric hybrid and electro-hydraulic hybrid.
Some manufacturers in Taiwan Province Province can produce it, and Qingdao Sentinel, a domestic manufacturer, may also produce it, but the failure rate and nail sticking rate are relatively high. Foreign manufacturers, such as Bosch and Atlas, have this technology, especially DEPRAG technology, which is relatively mature.
Supplement: Multi-head screws are generally transported by automatic nail feeder, which is produced by many domestic manufacturers.
There is no hand! A single axis weighs several hundred grams, and a multi-axis cannot be several kilograms to several hundred kilograms.
Looking at the number of shafts at a fixed price, the low-end shaft is about 5~20W, and the high-end shaft 4~6 may exceed 70W.
