[0019] The following is a detailed description of a roller pressing head for intelligent robots according to an embodiment of the present invention, with reference to the accompanying drawings.

[0020] Example

[0021] Figure 1 This diagram illustrates a three-dimensional structure of a roller pressing head for an intelligent robot, according to an embodiment of the present invention. Figure 2 This illustration shows a top view of a roller pressing head for an intelligent robot, provided by an embodiment of the present invention. Figure 3 A three-dimensional structural schematic diagram of the roller assembly provided in an embodiment of the present invention is shown; Figure 4 A bottom view of the roller assembly provided in an embodiment of the present invention is shown. Figures 1 to 4 As shown in the figure, the present invention provides a roller pressing head for intelligent robots, mainly used for roller pressing and bending forming operations on sheet metal workpieces. The roller pressing head for intelligent robots provided in this embodiment includes: a roller assembly 1, a pressure rod 2, a pressure sensor 3, and a connecting plate 4. Specifically, the roller assembly 1 is disposed at one end of the pressure rod 2 (i.e.,...). Figure 1The right end of the pressure rod 2 is rotatable to achieve the rolling operation of the workpiece. The intelligent robot's robotic arm drives the rolling head to move during the rolling process of sheet metal workpieces, thereby realizing the rolling of the rolling roller assembly 1 along the rolling direction on the surface of the sheet metal workpiece. The pressure sensor 3 is located between the pressure rod 2 and the connecting plate 4, and is mechanically connected to both the pressure rod 2 and the connecting plate 4 to monitor the force on the rolling head. Specifically, one side of the pressure sensor 3 is mechanically connected to the other end of the pressure rod 2, and the other side of the pressure sensor 3 is mechanically connected to the connecting plate 4. This embodiment shows a cylindrical structure of the pressure sensor 3. By electrically connecting the pressure sensor 3 to an external data acquisition system (such as a control cabinet in a workstation), real-time monitoring and data processing of the force on the intelligent robot's robotic arm can be achieved. This design allows the intelligent robot to make corresponding adjustments based on monitoring data to prevent uneven force during the rolling process, achieving precise control over the workpiece rolling process, improving workpiece rolling quality, preventing unevenness on the workpiece surface or edges, and preventing damage to the intelligent robot due to excessive force, thus improving equipment safety. The central axes of the pressure sensor 3, pressure rod 2, and connecting plate 4 are aligned to improve the accuracy of force monitoring and avoid significant deviations in the monitoring information of pressure sensor 3 due to uneven force. The connecting plate 4 mechanically connects to the robotic arm of the intelligent robot, enabling the intelligent robot to drive the rolling head to perform the rolling operation on the workpiece. This allows for intelligent control of the workpiece rolling process by the intelligent robot, further realizing intelligent control of the entire workstation and production line. It is worth noting that one end of the pressure rod 2 can be set as a single-sided notch or a central notch, allowing the rolling roller assembly 1 to be positioned at the notch, making the force direction of the rolling roller assembly 1 as close as possible to or coincident with the central axis of the pressure rod 2, thereby reducing force deviation of the pressure rod 2.

[0022] In a roller pressing head for an intelligent robot provided in this embodiment of the present invention, the roller pressing assembly 1 further includes: a roller shaft 101 and a bearing 102, wherein the bearing 102 is mechanically connected to the roller shaft 101 to enable the bearing 102 to rotate around the roller shaft 101, and the roller shaft 101 is mechanically connected to one end of the pressure rod 2, thereby enabling the roller pressing assembly 1 to rotate around the roller shaft 101, and the roller pressing assembly 1 is used to realize the roller pressing operation on the workpiece.

[0023] In a roller pressing head for an intelligent robot provided in this embodiment of the present invention, the roller pressing assembly 1 further includes a retaining spring 103. The retaining spring 103 is disposed at the lower end of the roller pressing assembly 1 to limit the position of the bearing 102, fix the bearing 102, and prevent the bearing 102 from moving axially, thereby improving the accuracy of the roller pressing.

[0024] In a roller pressing head for an intelligent robot provided in this embodiment of the present invention, one end of the pressure rod 2 is provided with an end face 201, and the cylindrical surface of the roller assembly 1 is in the direction along the axis of the pressure rod 2 (i.e., Figure 2 The end face 201 of the pressure rod 2 should be flush with or protrude from the right end of the center axis of the pressure rod 2. This is to prevent the end face 201 of the pressure rod 2 from interfering with the position of the workpiece during the rolling process and to ensure good contact between the cylindrical surface of the roller assembly 1 and the workpiece. Of course, the end face 201 can be a plane or a curved surface (such as a sphere or a cylinder), including but not limited to the above forms. The shape of the end face 201 is not specifically limited here, as long as it does not interfere with the roller assembly 1 during the rolling process of the workpiece.

[0025] Compared with the prior art, the roller pressing head for intelligent robots provided in this embodiment of the utility model has a reasonable design and simple structure. By using pressure sensor 3, the intelligent robot realizes real-time monitoring and control of the roller pressing head during the rolling process, which improves the rolling quality, consistency, safety and intelligence.
