Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, and in particular to a feeding mechanism. Background Technology

[0002] After the sprue is removed, aluminum die-cast parts such as lampshades require grinding of the edges and some cut surfaces to remove burrs, sharp edges, and cutting marks. In related technologies, this grinding work is done manually in conjunction with mechanical grinding, which is not only inefficient but also labor-intensive. Current methods utilize robotic equipment to assist grinding, creating an automated grinding process. For example, document CN216029927U discloses a six-axis robotic grinding device.

[0003] Robotic grinding requires continuous material feeding. In the subsequent processing of the workpiece, the workpiece needs to be fed in an orderly manner and leveled before the robot can pick it up and process it.

[0004] The existing feeding mechanism has only one feeding station. After feeding is completed, the machine needs to be paused before feeding is resumed and then restarted, which is very time-consuming. In addition, the existing feeding mechanism does not have the function of automatically leveling the workpiece, which makes the gripping position inaccurate and affects the technical problem of subsequent processing accuracy of the workpiece. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism that solves the problem of inaccurate gripping position affecting the subsequent processing accuracy of the workpiece.

[0006] To achieve the above objectives, the solution adopted by this utility model is: a feeding mechanism, the feeding mechanism comprising;

[0007] A material transfer device is provided with a material transfer area. The material transfer device includes two staggered material transfer mechanisms. The two material transfer mechanisms can move alternately into the material transfer area. The material transfer mechanisms are used to carry the workpiece to be processed.

[0008] A leveling device includes a connecting frame and a connecting plate fixed to the connecting frame. The connecting plate is inclined and has multiple rolling elements mounted on its surface. The multiple rolling elements form a movable plane. The connecting plate is provided with multiple limiting rods, which are used to position the edge of the workpiece.

[0009] A mobile device is provided with a gripper mechanism, which moves between the material transfer device and the leveling device.

[0010] In this solution, a material transfer device is set up so that the workpiece is placed on one transfer mechanism and then moves to the transfer area, while another transfer mechanism is ready for use, thus forming a continuous material supply. The gripper mechanism moves along the moving device, grabs the workpiece located in the transfer area from the transfer mechanism, and moves it to the leveling device for leveling and fixing. The gripping position is accurate and will not affect the subsequent processing of the workpiece.

[0011] Preferably, the material transfer device further includes a positioning frame, on which two material transfer slides are provided, and each of the material transfer slides can be slidably provided with one of the material transfer mechanisms.

[0012] In this solution, two material transfer slides are installed by setting a positioning frame. After the workpiece is transported by one material transfer mechanism, the material transfer mechanism moves to the loading point, and the other material transfer mechanism moves along the material transfer slide to the material transfer area to continue loading. With two material transfer mechanisms, the loading will not stop, saving processing time.

[0013] As a further preferred embodiment, each of the material transfer mechanisms includes a sliding plate, a bracket, and a support plate; the sliding plate is slidably connected to each of the material transfer slide bars, the bracket is provided at the upper end of the sliding plate, and the support plate is provided at the upper end of the bracket.

[0014] In this scheme, a support plate is set up, the workpiece is installed on the support plate, and the sliding plate slides along the material transfer slide rod to drive the bracket and the support plate to slide, so as to transport the workpiece to the material transfer area.

[0015] As a further preferred embodiment, the material transfer mechanism further includes fixing rods, and the upper end of the support plate is provided with a plurality of fixing rods for positioning the workpiece.

[0016] In this solution, by setting a fixed rod, the workpiece can be positioned, making the workpiece placement more accurate and preventing it from shifting.

[0017] As a further preferred embodiment, the two material transfer slides are arranged parallel to each other vertically, and the position height of the material transfer mechanism on the upper material transfer slide is lower than the position height of the support plate on the lower material transfer slide.

[0018] In this solution, by setting up parallel material transfer slide bars, the sliding of the two material transfer mechanisms will not interfere with each other.

[0019] As a further preferred embodiment, a driving mechanism is provided on the lower side of each of the material transfer slide bars. The driving mechanism is connected to the sliding plate to drive the sliding plate to slide along the material transfer slide bar to feed materials.

[0020] In this solution, a driving mechanism is used to drive the sliding plate to slide along the material transfer slide bar.

[0021] Preferably, the rolling element is configured as a bullseye bearing.

[0022] In this design, the bullseye bearing has rolling steel balls that work together with multiple bullseye bearings to form a rolling support plane.

[0023] As a further preferred embodiment, multiple limiting rods are distributed on the two lower edges of the connecting plate.

[0024] In this solution, by setting a limit rod, the workpiece will automatically level itself due to gravity because the connecting plate is tilted, and the limit rod can prevent the workpiece from slipping.

[0025] As a further preferred option, the lines connecting the multiple limiting rods are arranged at right angles.

[0026] In this solution, the limiting rod positions the edge of the workpiece at a right angle. By setting a bullseye bearing, the moving device moves the workpiece to the connecting plate, and the workpiece is leveled by gravity. Then, the bullseye bearing is used to position and fix the workpiece so that it can automatically level itself for convenient subsequent processing.

[0027] Preferably, the moving device further includes a support frame and a guide rail, the guide rail being disposed on the support frame, the guide rail portion being disposed above the material transfer area, and the gripper mechanism being movably disposed on the guide rail.

[0028] In this solution, by setting a guide rail, the gripper mechanism grabs the workpiece and slides it along the guide rail to place the workpiece on the leveling device. Attached Figure Description

[0036] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0037] like Figures 1 to 4 As shown, this utility model discloses a feeding mechanism, which is set on a base platform 1 to form an overall regional feeding range. The feeding mechanism includes a material transfer device 2, a leveling device 3, and a moving device 4; the material transfer device 2 is set on the base platform 1, and a material transfer area 21 is set on the material transfer device 2. The material transfer device 2 includes two staggered material transfer mechanisms 22, which are movably set on the base platform 1 and can be alternately moved into the material transfer area 21. The material transfer mechanisms 22 are used to carry the workpieces to be processed.

[0038] The leveling device 3 is mounted on the base platform 1 and is used to fix the workpiece 5. The moving device 4 is mounted on the base platform 1 and is equipped with a gripper mechanism 41 for moving the workpiece 5 of the material transfer device 2 to the leveling device 3.

[0039] The leveling device 3 includes a connecting frame 31 and a connecting plate 32. The connecting frame 31 is mounted on the base platform 1, and the connecting plate 32 is mounted on the connecting frame 31, with the connecting plate 32 being inclined. Multiple rolling elements are mounted on the surface of the connecting plate 32, forming a movable plane. The connecting plate 32 is inclined overall, with its upper surface being a slope. The rolling elements are positioned on the slope of the connecting plate 32, and when a workpiece is placed on the movable plane formed by the rolling elements, the workpiece slides along the movable plane.

[0040] The connecting plate 32 is provided with multiple limiting rods 33. When the workpiece slides along the sliding plane, the limiting rods 33 are used to position the edge of the workpiece. Preferably, multiple limiting rods 33 are distributed on the lower edge of the connecting plate 32 to form an angled positioning of the workpiece edge, so as to keep the workpiece automatically positioned under its own weight.

[0041] Furthermore, as a preferred embodiment, the connecting plate 32 is provided with a plurality of bullseye bearings 34 for positioning the workpiece 5.

[0042] Specifically, in this embodiment, a connecting frame 31 is provided on the base platform 1, and a connecting plate 32 is inclinedly provided on the connecting frame 31. The connecting plate 32 is inclined downward, and multiple bullseye bearings 34 are provided at the upper end of the connecting plate 32. Multiple limiting rods 33 are provided on the two sides of the connecting plate 32 in the inclined direction. When the workpiece 5 is placed on the connecting plate 32, the two sides of the workpiece 5 abut against the limiting rods 33 under the action of gravity, and are then fixed and automatically leveled by the bullseye bearings 34.

[0043] Specifically, in this embodiment, the inclined connecting plate 32 supports and fixes the workpiece 5. The limiting rod 33 prevents the workpiece 5 from slipping because the inclined connecting plate 32 automatically levels the workpiece 5 under gravity. The bullseye bearing 34 moves the workpiece 5 onto the connecting plate 32, levels it under gravity, and then positions and fixes it to facilitate subsequent processing.

[0044] Specifically, in this embodiment, a material transfer device 2 is provided on the base platform 1, a moving device 4 is provided on one side of the material transfer device 2, and a leveling device 3 is provided on one side of the moving device 4. The material transfer device 2 is used for material transfer, the moving device 4 is used for gripping the workpiece 5 on the material transfer device 2, and the leveling device 3 is used to automatically level the material after the moving device 4 grips it and places it on it for subsequent processing. A material transfer area 21 is provided on the side of the material transfer device 2 closest to the moving device 4, and a loading area is provided on the side of the material transfer device 2 furthest from the moving device 4. The material transfer device 2 includes two staggered material transfer mechanisms 22. One material transfer mechanism 22 is located in the loading area for loading and waiting, and the other material transfer mechanism 22 is located in the material transfer area 21 for the moving device 4 to grip the workpiece 5. When the workpiece 5 of the material transfer mechanism 22 located in the material transfer area 21 is loaded, the positions of the two material transfer mechanisms 22 in the material transfer area 21 and the loading area are interchanged. Because the two material transfer mechanisms 22 are staggered, they do not affect each other during movement. The moving device 4 includes a gripper mechanism 41, which can adjust the angle; the gripper mechanism 41 can grip the workpiece 5 in the material transfer area 21 and move it to the leveling device 3.

[0045] Specifically, in this embodiment, after the material transfer device 2 places the workpiece 5 on one material transfer mechanism 22, it moves to the material transfer area 21, while another material transfer mechanism 22 stands by for use. The gripper mechanism 41 moves along the moving device 4 to grip the workpiece 5 located in the material transfer area 21 from the material transfer mechanism 22 and places it on the leveling device 3 for leveling and positioning. The gripping position is accurate and will not affect the subsequent processing of the workpiece 5.

[0046] like Figures 2 to 5 As shown, further, as a preferred embodiment, the material transfer device 2 also includes a positioning frame 23, on which two material transfer slide bars 24 are provided, and each material transfer slide bar 24 is slidably provided with a material transfer mechanism 22.

[0047] Furthermore, as a preferred embodiment, each material transfer mechanism 22 includes a sliding plate 221, a bracket 222, and a support plate 223; each material transfer slide bar 24 is slidably connected to a sliding plate 221, the upper end of the sliding plate 221 is provided with a bracket 222, and the upper end of the bracket 222 is provided with a support plate 223.

[0048] Furthermore, as a preferred embodiment, the material transfer mechanism 22 also includes fixing rods 224, and the upper end of the support plate 223 is provided with a plurality of fixing rods 224 for positioning the workpiece 5.

[0049] Furthermore, as a preferred embodiment, the two material transfer slides 24 are arranged parallel to each other vertically, and the position height of the material transfer mechanism 22 on the upper material transfer slide 24 is lower than the position height of the support plate 223 on the lower material transfer slide 24.

[0050] Furthermore, as a preferred embodiment, a drive mechanism 225 is provided on the lower side of each material conveying slide bar 24. The drive mechanism 225 is connected to the sliding plate 221 to drive it to slide along the material conveying slide bar 24 to feed materials.

[0051] Specifically, in this embodiment, a positioning frame 23 is provided on the upper end of the base platform 1. Two parallel material transfer slide rods 24 are provided on the positioning frame 23. A sliding plate 221 is slidably provided on each material transfer slide rod 24. A bracket 222 is provided on the upper end of each sliding plate 221. A support plate 223 is connected to the upper end of each bracket 222. Two fixing rod groups are provided around the upper end of each support plate 223. Each fixing rod group includes multiple fixing rods 224. The fixing rod groups divide the support plate 223 into two placement areas. Multiple workpieces 5 can be stacked vertically in each placement area. A driving mechanism 225 is provided at the lower end of each material transfer slide rod 24. The movable end of the driving mechanism 225 is connected to the sliding plate 221 to drive the sliding plate 221 to slide along the material transfer slide rod 24.

[0052] The drive mechanism 225 is a drive motor, and an electrical box is installed on the base platform 1, which is connected to the drive motor. The height of the material transfer mechanism 22 on the upper material transfer slide 24 is lower than the height of the support plate 223 on the lower material transfer slide 24, so that the two material transfer mechanisms 22 are staggered and will not interfere with each other when moving relative to each other.

[0053] Specifically, in this embodiment, two transfer slide bars 24 are installed by setting a positioning frame 23. After the workpiece 5 of one transfer mechanism 22 is transported, the transfer mechanism 22 moves to the loading point, and the other transfer mechanism 22 moves along the transfer slide bars 24 to the transfer area 21 to continue loading. There are two transfer mechanisms 22, so loading will not stop, saving processing time.

[0054] The workpiece 5 is mounted on the support plate 223. The sliding plate 221 slides along the material transfer slide bar 24, causing the bracket 222 and the support plate 223 to slide, thereby transporting the workpiece 5 to the material transfer area 21. The fixed rod 224 can position the workpiece 5, making the placement of the workpiece 5 more accurate and preventing it from shifting. By setting the material transfer slide bars 24 to be arranged vertically and horizontally, the sliding of the two material transfer mechanisms 22 will not interfere with each other. A drive mechanism 225 is set to drive the sliding plate 221 to slide along the material transfer slide bar 24.

[0055] The mobile device 4 also includes a support frame 42 and a guide rail 43. The support frame 42 is provided at the upper end of the base platform 1, and the guide rail 43 is provided on the support frame 42. The guide rail 43 is partially located above the material transfer area 21, and the gripper mechanism 41 is movably located on the guide rail 43.

[0056] Specifically, in this embodiment, a support frame 42 is provided at the upper end of the base platform 1, and a guide rail 43 is provided on the support frame 42. The guide rail 43 is partially located above the material transfer area 21, and the gripper mechanism 41 is movably mounted on the guide rail 43. The gripper mechanism 41 is similar to a robotic arm mechanism in the prior art, and can move in the vertical direction and adjust the angle; it can also slide in the horizontal direction along the guide rail 43. The gripper mechanism 41 is provided with a drive motor, which drives it to slide along the guide rail 43, and the drive motor is electrically connected to the electrical box; the gripper mechanism 41 can grip the workpiece 5 in the material transfer area 21 onto the connecting plate 32 of the leveling device 3.

[0057] Specifically, in this embodiment, by setting the guide rail 43, the gripper mechanism 41 grips the workpiece 5 and slides it along the guide rail 43 to place the workpiece 5 on the leveling device 3.
