Electric screwdrivers, also known as electric screwdrivers, are electric tools used for tightening and loosening screws. Due to its high precision and high efficiency, it has become an indispensable tool in the assembly industry. The voltage is divided into AC high voltage and DC low voltage. There are semi-automatic and fully automatic forms. The operation start mode includes push-down type and hand-press type.
Semi-automatic screwdriver: A. A screwdriver that does not automatically brake after reaching the set torque is called a semi-automatic electric screwdriver. Usually semi-automatic is designed as a manual push.
B. The voltage of the semi-automatic series is divided into AC high-voltage in-line type, and DC low-voltage type through power transformation.
Fully automatic screwdriver: A. A screwdriver that can completely automatically brake and stop after reaching the set torque is called a fully automatic electric screwdriver. B. Fully automatic electric screwdrivers are divided into two series, AC high voltage and DC low voltage. To operate the start mode with a hand screwdriver, you need to press and hold the start lever, or the pressure plate button, etc. with your finger.
Push-down screwdriver: No need to hold the start lever, or the platen button, etc. with your fingers to operate the start mode. It can be started by pressing directly on the workpiece. The AC high-voltage screwdriver does not require a separate power supply to convert the voltage, and is directly connected to the mains, which is quick to operate and takes up less space.
Low-voltage screwdriver: small size and light weight, driven by low-voltage DC motor, long life and high safety factor.
Vacuum suction type electric screwdriver: an suction part for sucking the screw is added to the head of the BL/CL/SS/a/VZ type screwdriver, and the screw is sucked to the head of the screwdriver head by vacuum negative pressure to save picking up action of the screw. It can also attract non-magnetic screws, slotted screws, etc., so the work efficiency is high. In addition, vacuum suction screwdrivers can also be used to eliminate dust that occurs during the screwing process.
Anti-static specifications: The former electric screwdriver discharges the static electricity on the workpiece from the screwdriver head through the ground, but the static electricity of the screwdriver itself cannot be eliminated. In particular, since screwdrivers are designed to be lighter and lighter and made of resin, the incidence of static electricity in the use environment is getting higher and higher. This kind of screwdriver is especially suitable for assembling computer peripheral products that are taboo against static electricity. From the body to the switch lever and screwdriver power cord, anti-static resin is used to protect the workpiece from static interference.
Dust-free and anti-static specifications: For screwdrivers used in a dust-free environment, in order to reliably absorb dust and other objects generated during the screw assembly process, a vacuum is formed in the screwdriver body and the suction part to absorb dust.
. In order to facilitate maintenance, the design structure of an independent vacuum pump is adopted.
Noise-free specification: The noise-free specification reduces electrical noise caused by the screwdriver.
Pistol-type specifications: The pistol-type electric screwdriver is ideal for horizontal assembly work. The pistol type also has noise-free specifications.
