Description

Technical Field

[0001] This invention belongs to the field of profile handling equipment, and specifically relates to an automated intelligent handling mechanism for profile production lines. Background Technology

[0002] Profile handling robotic arms are indispensable equipment in modern industrial production. Their main function is to transfer profiles from one production stage to the next, such as cutting, welding, or assembly. Traditional profile handling robotic arms typically use preset programs for control, fixing the profiles in a specific position via clamping devices for transport. This method cannot adaptively adjust the clamping position, meaning that traditional handling robotic arms can only be used in production equipment where the material unloading position is precisely fixed. Otherwise, problems such as unstable clamping and inconsistent placement postures can easily occur. These problems not only affect production efficiency but may also lead to profile damage or safety hazards.

[0003] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Summary of the Invention

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In the following embodiments, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, terms such as first, second, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown.

[0024] Reference Figures 1 to 4 An automated intelligent handling mechanism for a profile production line includes a rotating robotic arm. A clamping plate 20 is mounted on the movable end of the robotic arm. A mounting base 23 is mounted on the clamping plate 20 via a lifting structure 30. A central clamping roller 21 is mounted on the mounting base 23. Side clamping rollers 22 are mounted on both sides of the clamping plate 20. The central clamping roller 21 and the side clamping rollers 22 are arranged in an inverted isosceles triangle. The side clamping rollers 22 are connected to the clamping plate 20 via bearings 24. A pressure sensor 25 is mounted on the clamping plate 20 above the bearings 24. The side clamping rollers 22 are driven to rotate by an adjusting motor 26.

[0025] During clamping and handling, the central clamping roller 21 scoops into the bottom of the profile, and then the lifting mechanism drives the central clamping roller 21 to rise, so that the profile is clamped between the side clamping rollers 22 and the central clamping roller 21. Taking the central clamping roller 21 as the midpoint, when the weight distribution of the profile on both sides of the central clamping roller 21 is uneven, the pressure values ​​measured by the pressure sensors 25 on the side clamping rollers 22 on both sides will have a numerical difference. The adjusting motor 26 drives the side clamping rollers 22 to rotate, and the side clamping rollers 22 move the profile to adjust the position until the weight distribution of the profile on both sides of the central clamping roller 21 is uniform. Compared with the prior art, the present invention can adjust the clamping position when clamping the profile to ensure clamping stability and consistent posture when the profile is placed.

[0026] Furthermore, the design of the above structure allows for the placement of profiles according to the requirements of different equipment. For example, on production and processing equipment using conveyor belts, the profiles need to be placed longitudinally on the conveyor belt, meaning the length of the profile is aligned with the conveyor belt's transport direction. The handling mechanism described in this invention can place one end of the profile on the conveyor belt, and then use the rotation of the side clamping rollers in conjunction with the rotation of the conveyor belt to move the entire profile onto the conveyor belt, without requiring a specific length for the conveyor belt. In contrast, traditional handling robotic arms, unable to move their clamping positions, can only place the entire profile on the conveyor belt, which necessitates that the length of the conveyor belt be greater than the length of the profile.

[0027] To ensure clamping stability, the center clamping roller 21 includes an assembly end, a middle section, and a movable end. The assembly end is assembled and connected to the mounting base 23, and the movable end is provided with a pointed part. The pointed part design facilitates the center clamping roller 21 to scoop into the bottom of the profile, making it easier to clamp the profile. The outer diameter of the middle section is smaller than the maximum outer diameter of the movable end to prevent the profile from slipping off during handling due to operations such as flipping.

[0028] Furthermore, the side surfaces of the center clamping roller 21 and the side clamping roller 22 used for clamping are made of a soft material. This design increases the frictional resistance between the profile and the center clamping roller 21 or the side clamping roller 22, and avoids damage to the profile surface. The side surfaces of the center clamping roller 21 and the side clamping roller 22 are provided with anti-slip textures 27, which can increase the frictional resistance between the profile and the center clamping roller 21 or the side clamping roller 22.

[0029] In this invention, the lifting structure 30 includes a lifting seat 31 and a lifting screw 32. The lifting screw 32 is connected and fixed to the clamping plate 20. A lifting motor 35 for driving the lifting screw 32 is provided on one side of the lifting seat 31. The mounting base 23 is equipped with limiting posts 33 on both sides of the lifting screw 32, and the clamping plate 20 is provided with limiting sleeves 34 that are slidably assembled with the limiting posts 33. By controlling the lifting motor 35, the middle clamping roller 21 can move up and down to achieve the clamping function.

[0030] In this invention, the rotating robotic arm includes a base 10, on which a rotating seat 11 is mounted, rotating about the center of the base 10. A first rotating arm 12 is mounted on the rotating seat 11, and a second rotating arm is mounted at the end of the first rotating arm 12. A mounting joint 15 is mounted at the end of the second rotating arm, and a clamping plate 20 is fixedly mounted to the mounting joint 15. The second rotating arm includes a rotating arm base 13 and a connecting arm 14, rotating about the center of the rotating arm base 13. The mounting joint 15 is hinged to the end of the connecting arm 14. The rotating robotic arm can perform multi-degree-of-freedom rotation, and by setting different rotation programs, the handling mechanism can be adapted to different production processes.

[0031] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
