Problems solved by technology

[0002] With the development of modern industrial technology and the growth of market demand, more and more electric tightening tools have entered households and industrial sites. Electric tightening tools are sold all over the world, and the total output and export volume are among the top in the world. However, the electric tightening tools on the market are not only basically the same in appearance and function, but also have serious shortages in the fields of intelligence, informationization, and high-precision control. The design, safety and practicability are also not ideal, mainly reflected in the lack of tool innovation, low efficiency and backward technology, which restrict the long-term development and popularization of electric tightening tools
[0003] Existing tightening tools are mainly based on mechanical structure to achieve torque control and screw tightening, with low precision and extremely low efficiency. After repeated use, the tools need to be checked and calibrated repeatedly, resulting in low tightening yield and no guarantee of quality. Great hidden dangers of product quality
[0004] In the high-end tightening tools, it is only aimed at the problem of accurate tightening torque. For problems such as wiring error prevention and assembly error prevention, it still relies on the subjective initiative of the operator; for production management, it does not involve

Embodiment 3

[0067] see Figure 18 , Figure 18 It is a database workflow flow chart of the intelligent tightening tool of the present invention. This embodiment discloses an intelligent management method for an intelligent tightening tool, which provides an authority management module, a parameter setting module, a database storage module, and a database. The user data, wiring equipment data and template data are saved and regularly updated. The image acquisition module scans the equipment code and cable number and sends the scanned equipment code and cable code to the image processing module. The image processing module Algorithms are used to match the scanned image with the barcode or equipment code in the database. If the match is successful, the tightening power structure starts to run at the installation position. If the match fails, the image acquisition module continues to scan the information of the equipment. The above database interacts with the server at any time for user dat...
