[0002] A three-axis truss robot is an automated device commonly used for material handling and processing operations in industrial production lines. It usually consists of three linear motion axes and can move in the X, Y, and Z directions. This type of robot is widely used in manufacturing industries such as automobiles, electronics, and food processing, improving production efficiency and safety.

[0003] In the existing technology, although the three-axis truss manipulator can cover a larger working area and is suitable for various task requirements, there are still some problems in its use. For example, in actual use, the manipulator can only perform handling work in the area below it and cannot be turned to face the left area or the right area. When the manipulator carries larger materials to the highest point, the work cannot be completed due to excessive stacking of materials in the high space, resulting in a smaller high space. Therefore, a flip structure for a three-axis truss manipulator is proposed to solve the above problems. Utility Model Content

The driving member is fixed to the front face of the vertical shaft, and the output shaft of the driving member is connected to the front end of the connecting rod. The connecting block is fixed to the outside of the rotating shaft, and the bottom surface of the connecting block passes through the groove. The connecting block is connected to the claw hand.

[0007] Furthermore, a transverse axis is provided on the back of the vertical axis, longitudinal axes are provided at both ends of the transverse axis, and support columns are fixed at both ends of the longitudinal axis.

[0008] Furthermore, the connecting block is located behind the second gear, the connecting block is rotatably connected in the groove, and the width of the connecting block is equal to the width of the vertical axis.

[0010] Furthermore, a through hole for the connecting rod to pass through is provided on the vertical shaft, and a through hole for the rotating shaft to pass through is provided on the vertical shaft.

[0011] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The flipping unit 2 includes a driving member 21, a first gear 22, a second gear 23, a connecting rod 25, a rotating shaft 27 and a connecting block 24. A groove 26 is provided on the bottom surface of the vertical shaft 6. The connecting rod 25 is longitudinally rotated and connected in the groove 26, and both ends of the connecting rod 25 pass through the vertical shaft 6. The rotating shaft 27 is longitudinally rotated and connected in the groove 26, and both ends of the rotating shaft 27 pass through the vertical shaft 6. The rotating shaft 27 is located below the connecting rod 25. The first gear 22 is fixed to the outside of the connecting rod 25, and the second gear 23 is fixed to the outside of the rotating shaft 27. The first gear 22 is meshed with the second gear 23.
