Description

Technical Field

[0001] This utility model relates to a self-built fifth axis device for a robot. Background Technology

[0002] Currently, in the robotic palletizing industry, five-axis robots are preferred due to their advantages in cost, speed, and flexibility. However, only five axes (1 / 2 / 3 / 4 / 6) of a five-axis robot are drivable, while the fifth axis is not. When palletizing tasks require rotating the palletized product at an appropriate angle along the fifth axis, the five-axis robot cannot fulfill this requirement.

[0003] When faced with palletizing situations that require products to rotate along the fifth axis, existing users will abandon five-axis robots and choose six-axis robots to achieve this task. Although six-axis robots have one more degree of freedom than five-axis robots, enabling rotation along the fifth axis to cover this situation, using six-axis robots will lose the advantages of five-axis robots, such as high speed, high flexibility, and lower investment costs.

[0004] Therefore, a self-built fifth axis device for robots is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the existing defects and provide a self-built fifth axis device for robots, which enables five-axis robots to simultaneously palletize products horizontally and vertically.

[0006] The technical solution to achieve the above objective is: a self-built fifth axis device for a robot, comprising a connecting column, a rotary connecting assembly, and a rotary driving assembly; the upper end of the connecting column is connected to the sixth axis of the five-axis robot, and the lower end is connected to a palletizing fixture through the rotary connecting assembly; the rotary driving assembly is connected to the lower side wall of the connecting column, and the other end of the rotary driving assembly is connected to the palletizing fixture.

[0007] Preferably, the rotary connection assembly includes a rotary seat, a rotating shaft, and multiple connectors; the rotary seat is connected to the lower end of the connecting column, and the rotating shaft is rotatably connected inside the rotary seat; the multiple connectors are equidistantly connected to the upper surface of the palletizing fixture, and the multiple connectors are fixedly connected to both ends of the rotating shaft.

[0008] Preferably, the rotary drive assembly includes a tilting cylinder, a fixed base, a fixed clamp, and a hinged base; the lower end sidewall of the connecting column is connected to the fixed base, the middle part of the tilting cylinder is rotatably connected to the fixed base via the fixed clamp, the upper end face of the palletizing fixture is connected to the hinged base, and the output end of the tilting cylinder is connected to the hinged base.

[0009] Preferably, the plurality of the connectors are connected to one side of the upper end face of the palletizing fixture.

[0010] Preferably, the hinge seat is connected to the middle of the upper end face of the palletizing fixture.

[0011] The beneficial effects of this utility model are: the self-built fifth axis device of this robot makes up for the lack of freedom of the fifth axis of a five-axis robot, realizing the simultaneous horizontal and vertical palletizing of products by the five-axis robot, achieving a win-win situation in terms of functionality and cost. This device only adds simple parts such as connecting columns, flipping cylinders, and rotating shafts to the palletizing fixture to achieve flipping, replacing the function of the fifth axis, and has a simple structure.

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, a self-built fifth axis device for a robot includes a connecting column 1, a rotary connection assembly, and a rotary drive assembly. The upper end of the connecting column 1 is connected to the sixth axis of the five-axis robot, and the lower end is connected to a palletizing fixture 2 via the rotary connection assembly. The rotary drive assembly is connected to the lower side wall of the connecting column 1, and the other end of the rotary drive assembly is connected to the palletizing fixture 2. The upper end of the connecting column 1 is fixed to the sixth axis of the five-axis robot.

[0019] Specifically, the rotary connection assembly includes a rotary seat 3, a rotating shaft 4, and multiple connectors 5. The rotary seat 3 is connected to the lower end of the connecting column 1, and the rotating shaft 4 is rotatably connected inside the rotary seat 3. Multiple connectors 5 are equidistantly connected to the upper end face of the palletizing fixture 2, and multiple connectors 5 are fixedly connected to both ends of the rotating shaft 4. Multiple connectors 5 are connected to one side of the upper end face of the palletizing fixture 2. The rotary drive assembly includes a tilting cylinder 6, a fixed seat 7, a fixed clamp 8, and a hinge seat 9. The fixed seat 7 is connected to the lower side wall of the connecting column 1, and the middle part of the tilting cylinder 6 is rotatably connected to the fixed seat 7 via the fixed clamp 8. The upper end face of the palletizing fixture 2 is connected to the hinge seat 9, and the output end of the tilting cylinder 6 is connected to the hinge seat 9. The hinge seat 9 is connected to the middle of the upper end face of the palletizing fixture 2. The extension and retraction of the tilting cylinder 6 drives the palletizing fixture 2 to rotate and tilt around the rotary seat 3.

[0020] During operation, the robot moves the palletizing fixture 2 to the picking position to horizontally pick up the product. The robot picks up the product and moves it above the palletizing trolley. During the movement, when the palletizing fixture 2 needs to be flipped, the output end of the flipping cylinder 6 retracts, causing the palletizing fixture 2 to flip from horizontal to vertical, thereby changing the product's position to vertical. When the robot reaches the palletizing position, the palletizing fixture 2 places the flipped vertical product onto the trolley.

[0021] The self-built fifth axis device of this robot is installed on the sixth axis of the five-axis robot. When the product only needs to be stacked horizontally and does not need to be flipped, this mechanism does not move; when the product needs to be flipped and stacked vertically, this mechanism replaces the robot's fifth axis to complete the vertical stacking of the product. This device makes up for the lack of degrees of freedom of the fifth axis of the five-axis robot, realizing the simultaneous horizontal and vertical stacking of products by the five-axis robot, achieving a win-win situation in terms of functionality and cost. This device only adds simple parts such as connecting column 1, flipping cylinder 6, and rotating shaft 4 to the stacking fixture to achieve flipping, replacing the function of the fifth axis, and has a simple structure.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
