The invention relates to an electric screwdriver control circuit, an electric screwdriver and an automatic installation device for a threaded fastener, and belongs to the technical field of electric screwdrivers. The electric screwdriver control circuit comprises a motor module, a rotation detection module, a timing counting module, a signal input reading module, a controller and an execution module, wherein the rotation detection module is used for detecting rotation of a motor in the motor module and outputting a high-low level change signal capable of indicating the number of rotation turns; the timing counting module is used for receiving the high-low level change signal and converting the high-low level change signal into the number of rotation turns; the signal input reading module is used for reading the number of rotation turns and sending the number of rotation turns to the controller; the controller is used for sending a level signal for indicating the motor to stop rotatingto the execution module when the number of rotation turns reaches a set process number of turns; and the execution module is used for executing a corresponding control action after receiving the levelsignal, so that the motor in the motor module stops rotating. Through the electric screwdriver control circuit, the electric screwdriver and the automatic installation device, the improvement of thequality and efficiency of electric screwdriver tightening operation is facilitated.
Description
technical field [0001] The application belongs to the technical field of electric batch, in particular to electric batch control circuit, electric batch and screw fastener automatic installation equipment. Background technique [0002] Screws and other threaded fasteners are commonly used in the product assembly process. On the product assembly line, an electric screwdriver is used to fix the two parts to be joined together with screws. For example, when a variety of electronic components need to be processed together with a heat sink, take the IPM power module as an example. During the pre-processing of the IPM, screws are used to assemble the IPM and the heat sink. In the related technology, there are the following problems in the operation of the electric screwdriver: during the use of the electric screwdriver, the torque of the electric screwdriver may be distorted and abnormal, which makes the screw tightening operation unqualified, which leads to quality problems of th...
