[0018] The technical solutions in the present utility model will be described below in conjunction with the drawings in the present utility model.

[0019] It should be noted that: Similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0020] Please refer to Figures 1 to 2 , the present utility model provides a multi-axis robotic arm. In the prior art, the degree of freedom of robotic arms is often low, and it is often necessary for humans to move or carry them during operation, which is time-consuming and laborious. To solve the above technical problems, the present utility model optimizes the structure of the robotic arm to achieve more degrees of freedom control, facilitate operation, and improve the operation efficiency.

[0021] As shown in the figure, the multi-axis robotic arm includes a moving component and a six-axis robotic arm 1 disposed above the moving component. The six-axis robotic arm 1 can be a product directly purchased on the market, and a main tower 3 is disposed at the bottom of the six-axis robotic arm 1. The main tower 3 can move on the moving component, thereby driving the six-axis robotic arm 1 to move on the moving component. Through the setting of the moving component, more moving directions can be provided for the six-axis robotic arm 1, and thus the degrees of freedom of multiple axes and multiple angles can be realized, which can meet more complex working environments and improve the operation efficiency.

[0022] The moving component includes guide rails 2. As shown in the figure, there are 2 guide rails 2, which are respectively located on both sides of the main tower 3. A sliding block is disposed at the bottom of the main tower 3, and the sliding block can be slidably engaged with the guide rail 2. In addition, a ball screw 4 is disposed between the two guide rails 2. The ball screw 4 is driven by a driving motor 5. In addition, an inward groove strip 6 is disposed at the bottom of the main tower 3, and a threaded sleeve capable of sleeving outside the ball screw 4 is disposed in the groove strip 6. Under the action of the driving motor 5, the main tower 3 can move more flexibly along the guide rail 2 and the ball screw 4. This structure is more stable and smoother during movement.

[0023] To make the structure of the present device more perfect and more automated, a moving platform 7 is further provided. Preferably, the moving platform 7 is an AGV mobile vehicle. The moving component is disposed above the moving platform 7. In addition, driving wheels are disposed at the bottom of the moving platform 7. The moving platform 7 can be provided with a control system, such as a PCL controller, etc., to control the movement of the moving platform 7, so that it can reach the required working place more flexibly. The driving motor 5 can also be provided with a corresponding control module to make it more automated. In addition, support legs are further disposed at the bottom of the AGV mobile vehicle. When the AGV mobile vehicle travels to the processing station, the support legs can automatically contact the ground to ensure the stability of the entire robotic arm during work.

[0024] The working process of the present utility model is as follows:

[0025] The moving platform 7 is moved to the required processing position through the driving wheels of the moving platform 7, and then the processing area drives the ball screw 4 through the driving motor 5 to adjust the specific position of the six-axis robotic arm 1, so as to achieve multi-angle and multi-direction movement, and thus achieve the purpose of improving work efficiency.

[0026] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
