Abstract

The invention discloses a screwdriver. The screwdriver comprises a driving device, a screwdriver bit device, a control device and a photoelectric detection device for detecting whether a screw is locked tightly, wherein the driving device comprises a power mechanism and a transmission mechanism, and the power mechanism and the photoelectric detection device are both electrically connected with thecontrol device; the transmission mechanism comprises a transmission shaft which is in transmission connection with the power mechanism; the screwdriver bit device comprises a screwdriver bit mechanism, the screwdriver bit mechanism comprises a screwdriver bit which is rotationally connected with the transmission shaft; the photoelectric detection device, the screwdriver bit device and the power mechanism are mounted on the transmission mechanism. According to the screwdriver, when the screw is locked by the screwdriver and the photoelectric detection device detects that the screw is not tightly locked in place, the photoelectric detection device sends a non-locking signal to the control device, the control device receives the non-locking signal and controls the power mechanism to increasetorsion for continuous locking, so that screw locking yield is increased, and product quality is improved.

Description

technical field [0001] The invention relates to screw locking equipment technology, in particular to a screwdriver. Background technique [0002] At present, the production process of electronic assembly, hardware accessories, automobiles and other industries includes screw locking technology. The traditional method is to use pure manual operation for screw locking. This technology is not only time-consuming and laborious, but also has extremely low work efficiency. Now It has been replaced by the developed automatic locking screw machine. The electric screwdriver is one of the main components of the automatic locking screw machine, and it is a tool for turning screws. [0003] But there is following defective in existing electric screwdriver: [0004] It is impossible to detect whether the screw is locked in place, so it is difficult to control the yield rate of the screw, which affects product quality. Contents of the invention [0005] In order to overcome the defici...
