[0035] Working principle: Figure 5 The specific steps are as follows:

[0036] S1. Align the torque gun body 6 with the screw opening to be fixed, and the camera 5 captures the QR code on the small square boss;

[0037] S2, the camera 5 converts the scanned image into a digital signal and transmits it to the console 7, the console 7 completes the signal analysis, obtains the required torque value, and outputs a torque adjustment signal to the torque gun body 6;

[0038] S3, the torque gun body 6 starts to rotate and tighten the screw according to the adjusted torque value until the set torque value is reached.

[0039] More specifically, Figure 6 As shown, serial number 1 is the instrument panel skin, serial number 4 is the instrument panel steel frame. Serial number 2 is the screw mounting plate made according to the instrument panel structure, such as Figure 8 As shown, each screw installation hole is provided on the mounting plate, and a QR code is attached to the small square boss next to the hole. The torque gun 3 is composed of a camera 5, a torque gun body 6 and a console 7. Figure 7 As shown in the figure, the structure of the instrument panel assembly has different installation parts in different positions. In the figure, the position marked "a" is the connection between the plastic instrument panel skin and the steel instrument steel frame, which is the connection between plastic parts and steel parts; the position marked "b" is the connection between the plastic instrument panel skin parts, which is the connection between plastic parts and plastic parts; because the torque that can be withstood by plastic and steel parts, and plastic and plastic connections is different, two different installation torques are defined for the two assemblies.

[0040] The new structure torque gun has a camera 5 added near the gun head for real-time scanning of the QR code next to the fastener hole on the mounting plate 2.

The control system adjusts the output torque of the torque gun 3 according to the information to meet the requirements of fastener assembly. This automatic adjustment mechanism can ensure that the correct torque is automatically matched during the assembly process to complete the assembly, thereby improving the assembly efficiency and quality.

[0041] The utility model solves the following problems: 1. How to quickly and accurately identify the torque required for each fastener during the assembly process; 2. How to realize automatic adjustment of fasteners with different torque requirements. By setting a camera 5 near the head of the torque gun, real-time scanning of the QR code on the mounting plate 2 is realized, thereby intelligently identifying the required torque information. The camera 5 feeds back the QR code information to the control system, and the control system adjusts the torque output of the torque gun 3 according to the information, thereby realizing automatic adjustment of the torque of the electric gun and improving assembly accuracy and efficiency. It can also improve the work efficiency of the assembly line, reduce product defects caused by improper torque, and also reduce the labor intensity of workers due to frequent torque adjustments.
