[0002] With the development of robotics technology, robotic structures that utilize high speed, high precision, and a high load-to-weight ratio have attracted attention in the industrial and aerospace sectors. Robotic arms are complex systems characterized by high precision, multiple inputs and outputs, high nonlinearity, and strong coupling. Due to their unique operational flexibility, they have been widely used in industrial assembly, safety, and explosion protection.

[0003] Currently, in the manufacturing and processing field, researchers have developed hoisted robotic arms, primarily used for processing the upper or top surfaces of products. However, these existing hoisted arms are complex and occupy a large area, making them difficult to quickly install and use. Furthermore, due to structural limitations, they lack flexible adjustment of rotation angles and can interfere with adjacent robotic arms.

[0004] In view of this, this technical solution proposes a processing robot arm module with a top lifting structure. It adopts a modular installation structure and multiple moving axes to achieve multi-angle rotation. The overall structure is compact and adopts an assembleable mechanism.

[0026] DETAILED DESCRIPTION

[0027] as follows:

[0028] Please see the attached Figure 1-5 ,

[0029] The main structure includes a guide rail assembly 1 and a robotic arm assembly 2 located on the guide rail assembly 1. The guide rail assembly 1 includes a lifting bracket 12 and a lifting plate 10 arranged on the top of the lifting bracket 12. A slide 14 is provided under the lifting bracket 12, and a slide rail 15 is installed on the slide 14, and the slide 14 is located on the slide rail 15. A servo motor 11 for controlling the operation of the slide 14 is provided on one side of the lifting bracket 12. The robotic arm assembly 2 includes a first X-axis motor 21 arranged on one side of the mounting base 20, and a second X-axis motor 22 arranged on one side of the first X-axis motor 21. A Y-axis motor 23 connected to the processing head 24 is provided on one side of the second X-axis motor 22. The second X-axis motor 22 is connected to the processing head 24 through a transmission belt, and the top of the first X-axis motor 21 is connected to the slide 16 through a connector 25.

[0030] Here's how it works:

[0031] During operation, the servo motor 11 drives the slide 14 and the slide 16 to reciprocate on the slide rail 15, and the slide 16 drives the robotic arm assembly 2 through the connecting member 25. The first X-axis motor 21 of the robotic arm assembly 2 is used to drive the entire robotic arm assembly 2 to rotate on the X-axis. The second X-axis motor 22 arranged on one side of the first X-axis motor 21 is used to drive the processing head 24 on one side to rotate on the X-axis. The Y-axis motor 23 arranged on the processing head 24 is used to drive the processing head 24 to perform telescopic movement on the Y-axis.

[0032] Multiple robotic arm assemblies 2 can be installed on a single mounting bracket 12, depending on actual processing requirements. For example, two sets of robotic arm assemblies 2 can be used for coordinated processing. Assembly and disassembly of the robotic arm assembly 2 is also simple: simply disconnect the connector 25 from the slide 16 to remove the entire robotic arm assembly 2 from the mounting bracket 12. The robotic arms sliding on the slide rails 15 replace traditional long-arm mechanical structures, allowing them to operate independently of each other.

[0033] In a preferred embodiment of the present invention, the bottom surface of the slide 16 is provided with holes 18 for secure connection with the connector 25. Holes 18 are also provided on the sides and bottom of the slide 16. At least two slides 14 are provided on the slide rail 15. Holes 18 are also provided on the bottom, sides, and top of the slide 16 for docking with the slides 14. These holes 18 can be screw holes or other fixing holes.

[0034] In a preferred embodiment of the present invention, the connecting member 25 is a metal disc with an open hole structure.

[0035] The mechanical arm assembly 2 has a certain weight. If other materials are used as the lifting connector 25, the strength may not be enough. However, the use of a perforated metal disc as the connector 25 ensures the connection strength and the force is evenly distributed during rotation.

[0036] A preferred embodiment of the present invention is that a locking member 13 for fixing the slide 14 is provided on the side of the hanging bracket.

[0037] The locking member 13 is convenient for fast fixed connection and quick disassembly. The locking member 13 is a detachable locking mechanism matched with a latch and a screw.

[0038] A preferred embodiment of the present invention is that one end of the hanging bracket 12 is provided with an end cover 17 that can be opened for assembly.

[0039] By opening the end cover 17 , the length of the hanging bracket 12 can be extended and spliced.

[0040] The first axis of the lifting robot (not a manipulator) featured in this solution can be lengthened or shortened based on customer needs, allowing for flexible customization based on the specific dimensions of the machine. Conventional robots cannot accommodate this flexibility with their arm spans. The key advantage of this type of lifting robot with walking travel is the lack of blind spots directly below the Z-axis. This eliminates any spatial limitations during processes such as placing or placing products, assembling, screwing, gluing, loading and unloading, palletizing, handling, labeling, welding, and attaching auxiliary materials. The walking robot offers flexible installation options and can be mounted in either an inverted or upright position. The upright position, meaning it is hoisted from overhead, saves space on the machine floor and reduces collision risk. To increase efficiency, multiple robots can be hoisted simultaneously, with three being the most common method. Installed side by side, it takes up less space than a single scara-shaped lifting robot while achieving over three times the efficiency of a single robot. The three machines will not interfere with each other or collide in a small space. From a control logic perspective, regional position interlocking and the position difference of the linear axes can effectively avoid overlapping trajectory areas, thereby ensuring that the three robots will not collide in a small space and other risks, and perfectly solving the problem of collision of overlapping trajectories. In the horizontal space, the characteristics of the hoisting walking robot are that the first axis X-axis can use a linear motor to realize a dual-motor solution. Each mover hoists a hoisting robot, realizing multiple robots moving independently on one axis. Expanding to 5-axis and 6-axis hoisting walking robots effectively solves the problem of insufficient CT cycle time of a single robot and its inability to meet the requirements, thus perfectly solving the problem of high-speed, high-precision and high-efficiency application solutions at the optimal cost.

[0041] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. All equivalent structural transformations made by using the contents of the description and drawings of the technical solution of the present utility model under the conception of the technical solution of the present utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present utility model.
