Description
Technical Field
[0001] This utility model relates to the field of robotic arm technology, and in particular to a variable-distance robotic arm. Background Technology
[0002] Glass engraving technology is a high-precision glass processing technique that primarily uses CNC equipment to finely process hard and brittle materials such as glass. The core equipment of this technology is the glass engraving machine, which integrates multiple functions such as engraving, drilling, edge grinding, cutting, grooving, and precision forming, enabling high-precision processing of ultra-thin glass.
[0003] The loading and unloading process of a CNC engraving machine typically involves a suction nozzle picking up the workpiece to be processed from the material rack, then a robotic arm transporting the workpiece to the processing platform for engraving.

The spacing between the suction nozzles is determined at the factory and cannot be adjusted according to actual production needs, resulting in the equipment being unable to adapt to different sized material racks.

[0024] See Figures 1-3 This utility model provides a variable-distance robotic arm, including a robotic arm 1, a first adsorption element 2, and a second adsorption element 3. The robotic arm 1 is equipped with a first driving mechanism 4. Both the first adsorption element 2 and the second adsorption element 3 are mounted on the robotic arm 1. The first driving mechanism 4 is driven by the first adsorption element 2 and is used to drive the first adsorption element 2 to move, thereby adjusting the distance between the first adsorption element 2 and the second adsorption element 3. By driving the first adsorption element 2 to move through the first driving mechanism 4, the distance between the first adsorption element 2 and the second adsorption element 3 can be adjusted, allowing the robotic arm to adapt to different material racks and expanding its application range.

The first suction member 2 is fixed on the first guide rail 51. The first driving mechanism 4 drives the first guide rail 51 to move, and the first guide rail 51 drives the first suction member 2 on it to move synchronously, thereby adjusting the distance between the first suction member 2 and the second suction member 3. This allows the robotic arm to adapt to different material racks, expanding the applicability of the robotic arm.
[0026] In one embodiment, the robotic arm 1 is provided with a first transmission component 11, the first driving mechanism 4 includes a first driving motor 41, a first lead screw 42 and a first movable connecting block 43, the first movable connecting block 43 is movably disposed on the first lead screw 42, the first transmission component 11 is connected to the first movable connecting block 43, the first guide rail 51 is connected to the first transmission component 11, and the first adsorption component 2 is disposed on the first guide rail 51. The first drive mechanism 4 integrates core components such as the first drive motor 41, the first lead screw 42, and the first moving connecting block 43. Its overall structure is relatively compact, occupying little space, and boasts high transmission efficiency. It effectively converts the power of the first drive motor 41 into the linear motion of the first adsorption component 2, reducing energy loss. Driven by the first lead screw 42, power transmission is smooth, reducing impact and vibration during movement, making the first adsorption component 2 move more smoothly and lowering the risk of operational errors or component damage caused by shaking. The cooperation between the first lead screw 42 and the first moving connecting block 43 provides high transmission precision, accurately controlling the displacement of the first adsorption component 2 and ensuring its accurate movement position on the guide rail assembly 5, meeting the requirements of precision engraving machines and other equipment with high positioning accuracy.
[0027] It should be noted that the first movable connecting block 43 is helically mounted on the first lead screw 42, which can convert the rotation of the first drive motor 41 into parallel movement.
[0028] In one embodiment, the robotic arm 1 is equipped with a second drive mechanism 7, which is drivenly connected to the second guide rail 52 to drive the second adsorption member 3 to move. Simultaneously, the movement direction of the second adsorption member 3 is opposite to that of the first adsorption member 2. By driving the first adsorption member 2 and the second adsorption member 3 respectively through the first drive mechanism 4 and the second drive mechanism 7, the first adsorption member 2 and the second adsorption member 3 can be simultaneously driven to move closer together or to separate to both sides, thereby quickly adjusting the distance between the first adsorption member 2 and the second adsorption member 3 and improving the variable distance efficiency.
[0029] In one embodiment, the robotic arm 1 is provided with a second transmission component 12, the second drive mechanism 7 includes a second drive motor 71, a second lead screw 72 and a second movable connecting block 73, the second movable connecting block 73 is movably disposed on the second lead screw 72, the second transmission component 12 is connected to the second movable connecting block 73, the second guide rail 52 is connected to the second transmission component 12, and the second suction component 3 is disposed on the second guide rail 52.

It effectively converts the power of the second drive motor 71 into the linear motion of the second adsorption component 3, reducing energy loss. Driven by the second lead screw 72, power transmission is smooth, reducing impact and vibration during movement, making the second adsorption component 3 move more smoothly and lowering the risk of operational errors or component damage caused by shaking. The cooperation between the second lead screw 72 and the second moving connecting block 73 provides high transmission precision, accurately controlling the displacement of the second adsorption component 3 and ensuring its accurate movement position on the guide rail assembly 5, meeting the high positioning accuracy requirements of equipment such as engraving machines.
[0030] Similarly, the second movable connecting block 73 is helically mounted on the second lead screw 72, which can convert the rotation of the second drive motor 71 into parallel movement.

When the second driving mechanism 7 drives the second guide rail 52 to move, it can simultaneously drive the second adsorption element 3 and the fourth adsorption element 9 located on the second guide rail 52 to move. It can simultaneously adjust the distance between the first adsorption element 2 and the second adsorption element 3, as well as the distance between the third adsorption element 8 and the fourth adsorption element 9, to accommodate multiple material racks.
[0032] Specifically, the guide rail assembly 5 includes a first rotating block, a second rotating block, and a third guide rail. The two ends of the first guide rail 51 and the third guide rail are respectively connected to the first rotating block and the second rotating block.

[0033] In one embodiment, the robotic arm 1 is provided with a flipping mechanism 6, which is drivenly connected to the guide rail assembly 5 to drive the guide rail assembly 5 to flip.

[0034] In one embodiment, the flipping mechanism 6 includes a third drive motor 61 and a transmission assembly. The third drive motor 61 is mounted on the robotic arm 1.

The rotation of the output shaft of the third drive motor 61 drives the driving transmission gear to rotate, causing the synchronous belt 62 to rotate and drive the driven transmission gear, thereby causing the guide rail assembly 5 connected to the driven transmission gear to flip.
[0036] In one embodiment, vacuum nozzles are provided on the front and back surfaces of the first adsorption member 2, the second adsorption member 3, the third adsorption member 8, and the fourth adsorption member 9.
