[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1 , is an Internet of Things digital display wrench disclosed in an embodiment of the utility model, including a shell 1, the shell 1 includes a working part 11 and a handle part 12, a working component 2 is installed inside the working part 11, the working component 2 includes a driving motor, the output end of the driving motor is connected to a reducer, the output end of the reducer is connected to a striking hammer, the output end of the striking hammer is installed with an impact head, the working component 2 is installed on the working part 11, the impact head penetrates the working part 11 to output torque, a camera 31 is fixedly installed on the upper end of the handle part 12, an information code 32 is set at the working bolt position, the camera 31 is used to identify the information code 32 information, an integrated module 4 is fixedly installed near the lower side of the handle part 12, the integrated module 4 includes a program control module, a torque control module 41, an acceleration sensor 42 and a satellite positioning module 43 are fixedly installed on the integrated module 4, the acceleration sensor 42 obtains the number of impacts of the striking hammer, and the satellite positioning module 43 obtains the location information, a battery terminal 5 is plugged and installed at the bottom of the handle part 12, a display module 6 is fixedly installed on the handle part 12, the display module 6 displays the parameters of the integrated module 4, and a torque adjustment button is set on the side of the display module 6.
[0030] Specifically, an integrated module 4 including a torque control module 41, an acceleration sensor 42 and a satellite positioning module 43 is arranged at the bottom of the electric wrench, and various parameters of the wrench when in use are acquired through the integrated module 4.
[0031] In this way, the location information and time information are obtained through the satellite positioning module 43, and the environmental conditions of the current location are obtained by obtaining the location and time, and the temperature, humidity and other conditions of the current location are obtained to obtain the most suitable torque value for tightening the bolt, which makes it easier to control the torque output of the wrench through the acceleration sensor 42 and the torque control module 41, so that the bolt can be tightened to a better state.
[0032] In some feasible ways, the housing 1, the working component 2 and the battery terminal 5 are all prior art and will not be described here. A camera 31 is fixedly installed on the front side of the junction between the handle portion 12 and the working portion 11. The camera 31 cooperates with the information code 32 of the working bolt position to obtain the information of the bolt, and after tightening the bolt or performing other operations, the relevant parameters of the working component 2 are obtained to record the current working situation, so as to obtain the record during the next maintenance work, etc., wherein the camera 31 and the information code 32 can be set as a QR code scanner and a QR code, and the position information of the working position is obtained by scanning the QR code, so as to facilitate the retrieval of the corresponding work record.
[0033] An integrated module 4 is installed at the bottom, and the integrated module 4 includes a programmable module. The programmable module can be selected as a FU6861L single-chip microcomputer, which is used to process data from other sensors and related modules. A torque control module 41, an acceleration sensor 42 and a satellite positioning module 43 are arranged on the integrated module 4. During the striking process of the striking hammer, the reaction force will cause the wrench to swing as a whole. The acceleration sensor 42 obtains the acceleration during the swing, analyzes the torque generated by the striking hammer, and then feeds back to the torque control module 41, so that the torque control module 41 can obtain and adjust the actual torque output by the wrench. At the same time, the integrated module 4 is installed as a whole at the lower part of the handle 12. It should be understood that the swing generated during the striking process of the striking hammer is a circular motion around the bolt rotation axis. In the circular motion, the farther away from the rotation axis, the greater the swing amplitude. The acceleration sensor 42 is partially arranged at the lower part of the handle 12, so that the acceleration sensor 42 is in an area with a larger swing amplitude, which is convenient for obtaining a smaller swing, and then it is convenient to improve the control accuracy of the torque.
[0034] As a specific implementation of an Internet of Things digital display wrench provided in the application, the integrated module 4 includes a communication module 44, which transmits data from a torque control module 41, an acceleration sensor 42 and a satellite positioning module 43.
[0035] In general, during use, the use of the wrench needs to be recorded so that the status of the working position can be queried when it is used in the same position next time. By setting up a communication module 44, the use of the wrench is transmitted to a data storage location such as a cloud platform through the communication module 44. After the camera 31 obtains the information of the information code 32, the last working status of the working position is retrieved from the storage location and displayed through the display module 6. After the work is completed, the work record is uploaded.
[0036] In some feasible embodiments, the communication module 44 is connected to the program control module via a UART serial port.
[0037] Furthermore, the communication module 44 includes a LoRa communication module 441 and an MQTT communication module 442 , wherein the LoRa communication module 441 is used for on-site communication, and the MQTT communication module 442 is used for communication with a data cloud platform.
[0038] It should be understood that the LoRa communication module 441 is a low-power wide area network wireless communication module. When a work location includes multiple workstations, communication is carried out through the LoRa communication module 441 to exchange data between multiple wrenches in the multiple workstations. The MQTT communication module 442 is used for data exchange between the wrench and the cloud platform. By setting up two communication modules, the mutual interference between the on-site control and the cloud platform communication is reduced.
[0039] In some feasible embodiments, an antenna module is installed on the upper end of the handle portion 12 away from the camera 31 for communication with the communication module 44 .
[0040] As another specific implementation of an IoT digital display wrench provided in the application, the integrated module 4 is fixedly connected to a tilt sensor 45, and the tilt sensor 45 measures the deflection angle of the wrench.
[0041] In combination with specific usage scenarios, by setting up an inclination sensor 45, the posture of the wrench is collected during use. On the one hand, the position state of the bolt can be obtained through the inclination sensor 45, and on the other hand, by obtaining the initial posture and final posture of the wrench, the deflection angle of the bolt during the tightening process can be obtained, so as to better determine the state of the bolt.
[0042] In some feasible embodiments, the tilt sensor 45 may be a gyroscope.
[0043] As another specific implementation of an Internet of Things digital display wrench provided in the application, a current detection module 461, a voltage detection module 462 and a current amplification module 463 are provided in the integrated module 4.
[0044] In combination with specific usage scenarios, during the use of the electric wrench, the attenuation of the battery terminal 5 will cause voltage fluctuations, resulting in a decrease in output power, thereby affecting the constancy of the output torque. By setting a current detection module 461 and a voltage detection module 462, when the voltage changes, the current is amplified through the current amplification module 463 to maintain the stability of the motor output power and thus maintain the stability of the torque output.
[0045] In some feasible embodiments, the current detection module 461 and the voltage detection module 462 are current and voltage sampling circuits connected to the programmable control module, and can also be selected as an integrated circuit module for current and voltage sampling connected to the programmable control module. The current amplification module 463 is a current amplification circuit connected to the programmable control module, which maintains the stability of the motor output power by amplifying the current.
[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
