Description

Technical Field

[0001] This utility model relates to the field of gripper technology, and in particular to an integrated gripper for AGV lifting machines. Background Technology

[0002] Currently, AGV lifting machines are widely used in the field of automated workpiece gripping. Their core components are mostly modular independent gripper assemblies. These grippers usually rely on transmission structures such as motor-driven lead screws or slide rails to achieve basic gripping.

[0003] The existing technology has the following main drawbacks: the gripper holding and supporting position is fixed, lacking multi-dimensional flexible adjustment, making it difficult to adapt to workpieces of different sizes, shapes and physical properties. Especially when facing fragile, irregular or thin workpieces, the gripping stability is poor, which can easily cause the workpiece to slip or the surface to be damaged, thus limiting the application range of grippers in modern automated production lines. Utility Model Content

[0004] The purpose of this invention is to propose an integrated gripper for AGV lifting machines in order to solve the problem of fixed gripping and support positions of existing grippers.

[0005] To achieve the above objectives, the present invention employs the following technology: an integrated gripper for an AGV lifting machine, comprising a frame, grippers, the grippers being composed of clamping plates and support plates, the frame being equipped with a drive assembly capable of driving the two grippers to move and clamp the workpiece, and a pressing component capable of improving the stability of the clamped workpiece during transport.

[0006] The drive assembly includes a first positive and negative threaded rod rotatably mounted at the bottom of the frame. A first motor and a slide are fixedly mounted on the frame. Two movable frames are slidably mounted between the slides, and the movable frames are threaded onto the first positive and negative threaded rod. The clamping plate is fixedly mounted at the bottom end of the movable frame. The clamping plate is also equipped with an adjustment component that can adjust the support position of the support plate on the workpiece.

[0007] As a further description of the above technical solution: the adjustment component includes guide rails symmetrically mounted on the clamping plate, a mounting bracket and a fixing plate respectively disposed between the two guide rails, and an electric push rod fixedly mounted on one side of the fixing plate.

[0008] As a further description of the above technical solution: the output end of the electric actuator is fixedly connected to the mounting bracket, and the mounting bracket is slidably installed between two guide rails.

[0009] As a further description of the above technical solution: the mounting bracket is provided with a second positive and negative threaded rod and a second motor. The two ends of the second positive and negative threaded rod are threadedly connected to sliders. The support plate is fixedly installed on the sliders, and one side of the support plate is set as an inclined surface.

[0010] As a further description of the above technical solution: the second positive and negative threaded rods are rotatably installed inside the mounting bracket, and one end of the second positive and negative threaded rods extending to the outside of the mounting bracket is fixedly installed on the output end of the second motor.

[0011] As a further description of the above technical solution: the pressing component includes mounting grooves symmetrically opened on the clamping plate, the pressure plate is set on the mounting groove by a rotating rod, rubber pads and connectors are respectively provided on both sides of the pressure plate, and a connecting plate is provided between the connector and the mounting frame.

[0012] As a further description of the above technical solution: a torsion spring is provided between the rubber pad and the mounting groove. The torsion spring is located on the surface of the rotating rod, and the two sides of the connector are rotatably connected to the pressure plate and the connecting plate, respectively.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] By adjusting the position, extension length, and spacing of the support plate, the grippers can precisely adapt to workpieces of different sizes and shapes, easily gripping everything from large heavy objects to small precision parts. In production scenarios where workpiece specifications change frequently, the grippers do not need to be replaced; they can be quickly deployed to new tasks with simple adjustments, greatly improving production flexibility and continuity. When the mounting frame moves, it also drives the connecting plate to push the connector, which in turn pushes one end of the pressure plate and gradually tilts it. At this time, the rubber pad will come into contact with the top of the workpiece. As the pressure plate gradually tilts, it will gradually squeeze the rubber pad, increasing the friction between the workpiece and the pressure plate. Together with the support plate at the bottom, this will press and fix the workpiece, keeping it stable on the support plate and preventing displacement or shaking due to external forces.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 5 The integrated gripper for AGV lifting machine provided in this embodiment includes a frame 10, a gripper 11, the gripper 11 is composed of a clamping plate 111 and a support plate 112, the frame 10 is equipped with a drive assembly 20 that can drive the two grippers 11 to move and clamp the workpiece, and a pressing component 30 that can improve the stability of the clamped workpiece during transportation.

[0026] The drive assembly 20 includes a first positive and negative threaded rod 21 rotatably mounted at the bottom of the frame 10. A first motor 22 and a slide 23 are fixedly mounted on the frame 10. Two movable frames 24 are slidably mounted between the slide 23. The movable frames 24 are kept stable by the slide 23 when moving. The movable frames 24 are threaded onto the first positive and negative threaded rod 21. The rotation of the first positive and negative threaded rod 21 enables the two movable frames 24 to move toward opposite or opposite sides. A clamping plate 111 is fixedly mounted at the bottom of the movable frames 24. When the two movable frames 24 move, they also drive the jaws 11 connected at the bottom to move, thereby causing the two jaws 11 to move toward opposite or opposite sides, thereby clamping or releasing the workpiece. The clamping plate 111 is also equipped with an adjustment component 25 that can adjust the support position of the support plate 112 on the workpiece.

[0027] Reference Figure 3 - Figure 4Specifically, in order to support the workpiece, an adjustment component 25 is provided. The adjustment component 25 includes guide rails 251 symmetrically mounted on the clamping plate 111, a mounting bracket 252 and a fixing plate 253 respectively disposed between the two guide rails 251, and an electric push rod 254 is fixedly mounted on one side of the fixing plate 253.

[0028] In more detail, the output end of the electric actuator 254 is fixedly connected to the mounting bracket 252. The electric actuator 254 can drive the mounting bracket 252 to move. The mounting bracket 252 is slidably mounted between two guide rails 251, and the mounting bracket 252 is kept stable by the guide rails 251 on both sides when it moves.

[0029] In more detail, the mounting bracket 252 is equipped with a second positive and negative threaded rod 255 and a second motor 256. The two ends of the second positive and negative threaded rod 255 are threaded with sliders. When the second positive and negative threaded rod 255 rotates, the sliders on both sides will move towards the opposite or opposite sides. The support plate 112 is fixedly installed on the slider. The slider can drive the support plate 112 to move, so that the distance between the two support plates 112 can be adjusted to suit workpieces of different sizes. One side of the support plate 112 is set as an inclined surface. When the support plate 112 moves with the clamping plate 111, the support plate 112 located at the bottom of the clamping plate 111 will first contact the bottom of the workpiece. The inclined surface at the top of the support plate 112 will gradually lift the workpiece, and then the clamping plates 111 on both sides will hold the workpiece, while the support plate 112 is located at the top of the workpiece to support it.

[0030] Specifically, in order to adjust the distance between the two support plates 112, the second positive and negative threaded rod 255 is rotatably installed inside the mounting bracket 252, and one end of the second positive and negative threaded rod 255 extending to the outside of the mounting bracket 252 is fixedly installed on the output end of the second motor 256, so that the second positive and negative threaded rod 255 can be driven to rotate by the second motor 256.

[0031] In use, the AGV lifter moves the frame 10 to a suitable position. Then, the first motor 22 is started, which drives the first positive and negative threaded screw 21 to start rotating. The moving frames 24 on both sides will start to move towards the opposite side, thereby driving the bottom gripper 11 to move towards the opposite side. The support plate 112 at the bottom of the clamping plate 111 will first contact the bottom of the workpiece. The workpiece is gradually lifted by the inclined surface at the top of the support plate 112. Then, the workpiece is clamped by the clamping plates 111 on both sides. Next, the electric push rod 254 is started to drive the mounting frame 252 to move, so that the mounting frame 252 drives the support plate 112 to extend outward, so that the support plate 112 extends to a suitable length to support the workpiece.

[0032] If the size of the workpiece is smaller than the distance between the support plates 112, the second motor 256 is started, which drives the second positive and negative threaded rod 255 to rotate. As a result, the slider will move the support plates 112 toward opposite or opposite sides, thereby changing the distance between the two support plates 112, which is suitable for workpieces of different sizes.

[0033] Reference Figure 5 Specifically, in order to improve the stability of the workpiece during clamping, a pressing component 30 is provided. The pressing component 30 includes mounting grooves symmetrically opened on the clamping plate 111. The pressure plate 31 is set on the mounting groove via a rotating rod. The pressure plate 31 can rotate via the rotating rod. Rubber pads 32 and connecting parts 33 are respectively provided on both sides of the pressure plate 31. The rubber pads 32 can increase the friction between the workpiece and the pressure plate 31. A connecting plate 34 is provided between the connecting part 33 and the mounting bracket 252.

[0034] In more detail, a torsion spring is provided between the rubber pad 32 and the mounting groove. The torsion spring allows the rubber pad 32 to rotate and return to its original position. The torsion spring is located on the surface of the rotating rod. The two sides of the connector 33 are rotatably connected to the pressure plate 31 and the connecting plate 34, respectively. When the mounting bracket 252 moves, it will also drive the connecting plate 34 to move. One end of the connecting plate 34 will push the connector 33, which will push one end of the pressure plate 31. The pressure plate 31 will then start to rotate and gradually tilt through the rotating rod. At this time, the rubber pad 32 will contact the top of the workpiece. As the pressure plate 31 gradually tilts, it will gradually squeeze the rubber pad 32. The rubber pad 32 increases the friction between the workpiece and the pressure plate 31. Together with the bottom support plate 112, the workpiece can be pressed and fixed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
