Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Figure 1 This is a structural schematic diagram of the explosion-proof six-axis robot in this utility model; Figure 2 This is a schematic diagram of the structure of the first explosion-proof motor and the auxiliary arm in this utility model; Figure 3 This is a schematic diagram of the structure of the second explosion-proof motor and the auxiliary boom in this utility model. Please refer to [link / reference]. Figures 1 to 3The diagram illustrates a preferred embodiment of an explosion-proof six-axis robot, comprising a rotating base 1, a main arm 2, a secondary arm 3, a connecting seat 4, a first explosion-proof motor 5, and second explosion-proof motors 6. The main arm 2 is rotatably mounted on the upper end of the rotating base 1, and the connecting seat 4 is rotatably mounted on the upper end of the main arm 2. One end of the secondary arm 3 is rotatably connected to the connecting seat 4. The first explosion-proof motor 5 is mounted on one side of the connecting seat 4 and is connected to the secondary arm 3 via a first transmission mechanism. Two second explosion-proof motors 6 are mounted on one end of the connecting seat 4 and are connected to one end of the secondary arm 3 via a second transmission mechanism. An end effector is mounted on the other end of the secondary arm 3. In this embodiment, the secondary arm 3 is driven to rotate by the combined first and second explosion-proof motors 5 and 6, significantly increasing the driving torque of the secondary arm 3 compared to traditional single servo motor drives.

[0026] In this embodiment, the first transmission mechanism includes a driving gear 8 and a driven gear 9. The driven gear 9 is provided on the outer wall of one end of the auxiliary arm 3, and the driving gear 8 is provided on the output shaft of the first explosion-proof motor 5. The driving gear 8 meshes with the driven gear 9, providing driving force in one direction. The second transmission mechanism includes a first gear 11 and a second gear 12. The first gear 11 is provided in the middle of the mounting plate 10 installed at one end of the auxiliary arm 3, and the second gear 12 on the output shaft of each second explosion-proof motor 6 meshes with the first gear 11, providing driving force to the auxiliary arm 3 from another direction. In the rotation or handling of large parts, when the load weight increases to the point that a traditional single servo motor cannot drive the auxiliary arm 3 to rotate, the auxiliary arm 3 in this embodiment can easily complete the handling task by relying on the coordinated action of multiple explosion-proof motors, effectively improving the working efficiency and reliability of the robot under heavy load conditions.

[0027] Furthermore, as a preferred implementation, all motors of the explosion-proof six-axis robot are explosion-proof motors. In this embodiment, based on the existing explosion-proof six-axis robot, all motors of the explosion-proof six-axis robot are set as explosion-proof motors, and the wiring connected to the motors is treated with explosion-proof technology. In addition, the overall structure of the explosion-proof six-axis robot can also be treated with explosion-proof technology. For example, the cables connected to each motor in the explosion-proof six-axis robot are also treated with explosion-proof technology to improve the safety of use. The first explosion-proof motor 5 is connected to the connecting seat 4 through the mounting base 7. The two second explosion-proof motors 6 are connected to one end of the connecting seat 4 through the motor bracket 13. Each second explosion-proof motor 6 has a bearing seat 14 on its output shaft, and the bearing seat 14 is connected to one end of the connecting seat 4. This arrangement can ensure the stability of the motor installation.

[0028] Furthermore, as a preferred embodiment, the axis of the auxiliary arm 3, the axis of the mounting plate 10, and the axis of the first gear 11 are arranged collinearly, and the two second gears 12 are located on both sides of the first gear 11 and mesh with the first gear 11, thereby driving the first gear 11 to rotate.

[0029] In this embodiment, during use, the cooperation of the first explosion-proof motor 5 and the second explosion-proof motor 6 enhances the load-bearing capacity of the auxiliary arm 3 and makes its movement more stable. The first explosion-proof motor 5 and the second explosion-proof motor 6 can be connected to the robot control system. By controlling the operation of the first explosion-proof motor 5 and the second explosion-proof motor 6 through the robot control system, the forces on the auxiliary arm 3 during movement can be better balanced, which helps improve the robot's working accuracy. Furthermore, the explosion-proof design enables the explosion-proof six-axis robot to effectively resist the influence of external factors on the electrical system in harsh industrial environments, reducing the frequency of failures and ensuring long-term stable operation of the robot.

[0030] In this embodiment, the motor bracket 13 and the connecting seat 4 are welded or bolted together. The second explosion-proof motor 6 can be bolted to the motor bracket 13. The mounting seat 7 and the connecting seat 4 are bolted together. The first explosion-proof motor 5 is bolted to the mounting seat 7.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
