Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a multifunctional switchable robotic arm. Background Technology

[0002] Traditional robotic arms often employ rigid structural designs, making it difficult to quickly replace or combine the functional modules of their joints and end effectors. For example, robotic arms on industrial production lines are typically customized for specific tasks (such as welding, handling, and assembly), with their mechanical structure, drive methods, and control logic deeply tied to task requirements. This "specialized" design leads to frequent equipment replacements or reprogramming when faced with complex and ever-changing production demands, resulting in resource waste and inefficiency. For instance, in the automotive manufacturing industry, a robotic arm designed for car body welding cannot be directly used for assembling precision electronic components, requiring additional equipment and significantly increasing the company's hardware investment costs. The limited functionality results in low equipment utilization and an inability to flexibly adjust to task requirements. Furthermore, existing robotic arm transmission systems often use single-motor drives, lacking multi-level linkages and resulting in insufficient stability and precision.

[0003] Therefore, a multifunctional switchable robotic arm needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: In use, firstly, the base 1 is fixed on the workbench. Different replacement components are installed according to the requirements. When vertical plane motion control is performed, the connecting frame 13 is fixed to the first worm gear 7 with screws. At the same time, the first motor 3 is turned on, so that the first motor 3 causes the first driving wheel 10 and the first synchronous wheel 12 to rotate synchronously through the first driven wheel 11. This causes the first worm 8 to drive the first worm gear 7 to rotate, thereby enabling the first replacement component to achieve a vertical swing range of ±110° for the initial vertical angle adjustment. At this time, the second... The second motor 16 causes the second driving wheel 20 and the second synchronous wheel 22 to rotate synchronously via the second driven wheel 21, thereby causing the second worm 19 to drive the second worm wheel 18 to rotate. This allows the connecting seat 23 to be adjusted within a 360-degree horizontal angle range. Then, the third motor 24 is activated, causing the pinion 25 and the large gear 29 to rotate synchronously, thereby causing the third worm to drive the third worm wheel 27 to rotate. Therefore, in use, the third worm wheel 27 can be connected to the workpiece to be controlled for secondary left and right angle control.

[0025] Example 2: When switching the second replacement component, horizontal motion control is performed. The second connecting frame 30 is fixed to the first worm gear 7 with screws. The rotation angle of the second replacement component is adjusted by the first motor 3 to achieve the initial vertical adjustment of ±110°. The fourth motor 32 is turned on, so that the third driving wheel 38 and the third synchronous wheel 40 rotate synchronously through the third driven wheel 39, thereby causing the fourth worm 52 to drive the fourth worm gear 36 to rotate, thus allowing for a second adjustment of the rotation angle of the second replacement component. The fifth motor 44 is turned on, so that the fourth driving wheel 48 and the fourth synchronous wheel 50 rotate synchronously through the fourth driven wheel 49, thereby causing the fifth worm 47 to drive the fifth worm gear 46 to rotate, thus achieving a horizontal rotation of ±180° for the mounting base 51. In use, the third worm gear 27 can be connected to the workpiece to be controlled and adjusted. Composite motion control is achieved through a three-stage transmission system.

[0026] In summary, different replacement components can be selected according to different needs to achieve different functions and improve the versatility of the device's functions.
