Smart-Screwdriver

The first AI vision screwdriver control system

Patent application number:2021108198383

Smart-ScrewdriverProducts

Smart Screwdriver console uses a telescopic motor connected to a spring, through the compression of the spring can control the output torque of the reducer; through the stroke of the motor, it can control the compression amount of the compression spring; according to the compression amount, the output torque is precisely controlled to achieve digital torque adjustment. Meanwhile, by installing or wearing a wearable camera above the operation area, the camera will continuously collect visual images of the operation and transmit them to the AI module for screw model and position identification; if the current screw model or position is found to be wrong, invalid torque output and warning messages will be displayed and must be adjusted before the operation can continue. Smart Screwdriver allows users to remotely configure the parameters of the screwdriver, remotely monitor the operation of the screwdriver, and analyze the operation data, thus promoting product quality control. Also based on the scenario design of Industrial Internet of Things, using MQTT and MES system for data transmission, users can define the operation content according to MPI requirements, breaking through the hardware and software barriers to achieve software-defined operations.

Core Functions

Visual intelligence against dumbing down

A wearable camera is installed or worn above the operation area. The camera will continuously collect visual images of the operation and transmit them to the AI terminal, and the AI module will identify the screw model and position of the received images; if the current screw model or position is found to be wrong, an intelligent warning will be given, displaying invalid torque output and warning messages; the user must make adjustments before continuing the operation.

Torque closed loop control

The motor torque is estimated by a certain algorithm to calculate a more accurate current torque of the motor, and the torque is controlled in closed loop. The dynamic torque sensor is integrated in the bottom of the screwdriver to collect the output torque value during the operation. The collected torque value is compared with the set value in real time, and once the set value is exceeded, the motor power output will be shut down, and the digital display will send an alarm signal and display an error message in the system. The user loosens the screw and retightens it according to the prompt message.

Software Defined Operations

This product adopts artificial intelligence technology, which allows users to remotely define the job content, remotely configure the parameters of the screwdriver, remotely monitor the operation of the screwdriver, and analyze the operation data through the system according to MPI requirements, thus promoting the quality control of the product. By breaking the barrier between software and hardware, the two can be integrated faster, thus saving manpower and time and improving the efficiency of enterprises.

Torque Smart Calibration

The torque of the screwdriver is calibrated by the torque sensor, and the error accuracy of the torque loop is monitored in time according to the historical data of torque control and closed-loop comparison data; once the control accuracy exceeds the requirement an intelligent warning will be made to prompt the user to calibrate the torque. The user will fix the screwdriver on the specified screw, and the screwdriver will be automatically calibrated for accuracy, which improves work efficiency and saves manpower.
