[0002] The robot arm refers to a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. The handling robot arm can increase the packing speed of finished products, grab them in batches through the robot arm, and put them into the packaging box, reducing manual labor;

[0003] The existing robotic arms of cartoning machines have a relatively simple structure when in use. They use vacuum suction cups to suck up objects for transportation. When the shapes of the objects are special, the area of ​​adsorption of the objects by the robotic arms is small, which may lead to insufficient suction and cause the objects to fall off. The objects are easily broken when they fall, and the handling dimensions of the robotic arms are usually fixed, which has poor applicability. Utility Model Content

[0004] The main purpose of the utility model is to provide a mechanical arm of a case packing machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A mechanical arm of a case packing machine comprises a mechanical arm body, a mounting frame is installed at the front end of the mechanical arm body, and a clamping assembly is arranged at the bottom end of the mounting frame;

[0007] The clamping assembly includes a vacuum suction cup 1 and a threaded rod. The vacuum suction cup 1 is fixedly connected and installed at the rear position of the bottom end of the mounting frame. The threaded rod is rotatably installed inside the mounting frame. The outer ring of the threaded rod is threadedly connected with a vacuum suction cup 2, and the size of the vacuum suction cup 2 is consistent with that of the vacuum suction cup 1. The ends of the vacuum suction cup 1 and the vacuum suction cup 2 that are away from each other are fixedly connected with a connecting plate. A sliding groove is provided at the lower part of the two connecting plates, and a support plate is slidably installed in the sliding groove. An electric telescopic rod is installed on one side of the connecting plate, and the push rods of the two electric telescopic rods are respectively connected to the ends of the two support plates that are away from each other.

[0008] As a further solution of the utility model, the size of the support plate matches the size of the lower part of the connecting plate, and the bottom ends of the two support plates are connected to a push plate near the center point of the mounting frame through fixing bolts.

[0009] As a further solution of the utility model, the connecting plate is arranged in an "L" shape, and a movable groove matching with the push plate is opened at the bottom end of the connecting plate.

[0010] As a further solution of the utility model, an adjusting motor is installed at a center position of the front end of the mounting frame, and the shaft of the adjusting motor is connected to the front end of the threaded rod.

[0011] As a further solution of the utility model, the top of the vacuum suction cup 2 is fixedly connected to limit blocks on both sides, and a sliding rod is slidably connected to the front and rear ends of the limit blocks, and the two ends of the sliding rod are fixedly connected to the inner wall of the mounting frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model provides a clamping assembly to cooperate with the mechanical arm body. When the vacuum suction cup 1 and the vacuum suction cup 2 suck the workpiece, the support plate is used to lift the object clamped by the vacuum suction cup 1 and the threaded rod. The support plate plays a bearing role and can prevent the object from falling directly when the vacuum suction cup 1 and the threaded rod have insufficient suction force. At the same time, a push plate is installed at the bottom of the support plate, which can open the box opening when packing to prevent the box opening from blocking the placement of objects.

[0014] By setting up an adjustment motor and a threaded rod in conjunction with the vacuum suction cup 2, before clamping, the adjustment motor can be rotated to drive the threaded rod to rotate, so that the vacuum suction cup 2 can be driven closer to or away from the threaded rod, thereby adjusting the handling size, making it easier to adjust the suction size according to the size of the object and improving applicability.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, a mechanical arm of a case packing machine comprises a mechanical arm body 1, a mounting frame 2 is mounted on the front end of the mechanical arm body 1, and a clamping assembly 3 is arranged at the bottom end of the mounting frame 2;

[0021] The clamping assembly 3 includes a vacuum suction cup 4 and a threaded rod 5. The vacuum suction cup 4 is fixedly connected and installed at the rear position of the bottom end of the mounting frame 2. The threaded rod 5 is rotatably installed inside the mounting frame 2. The outer ring of the threaded rod 5 is threadedly connected with a vacuum suction cup 2 6, and the size of the vacuum suction cup 2 6 is consistent with that of the vacuum suction cup 1 4. The ends of the vacuum suction cup 1 4 and the vacuum suction cup 2 6 that are away from each other are fixedly connected with a connecting plate 7. A slide groove 8 is provided at the lower part of the two connecting plates 7. A support plate 9 is slidably installed in the slide groove 8. An electric telescopic rod 10 is installed on one side of the connecting plate 7, and the push rods of the two electric telescopic rods 10 are respectively connected to the ends of the two support plates 9 that are away from each other.

[0022] In this embodiment, the size of the support plate 9 matches the size of the lower part of the connecting plate 7, and the bottom ends of the two support plates 9 are connected to the push plates 11 near the center point of the mounting frame 2 through fixing bolts 12. The support plates 9 are moved by the electric telescopic rod 10, so that the two driven push plates 11 are moved away from each other, making it easier to open the box opening and avoiding the box opening from blocking objects.

[0023] In this embodiment, the connecting plate 7 is set in an "L" shape, and a movable groove matching the push plate 11 is opened at the bottom of the connecting plate 7. The movable groove can prevent the connecting plate 7 from affecting the movement of the push plate 11.

[0024] In this embodiment, an adjusting motor 14 is installed at the center of the front end of the mounting frame 2. The shaft of the adjusting motor 14 is connected to the front end of the threaded rod 5. The threaded rod 5 is driven to rotate by the rotation of the shaft of the adjusting motor 14. The rotation of the threaded rod 5 pushes the vacuum suction cup 2 6 to move, which makes it easy to control the vacuum suction cup 2 6 to move away from or close to the vacuum suction cup 1 4, thereby adjusting the distance between the two.

[0025] In this embodiment, the top of the vacuum suction cup 2 6 is fixedly connected to the limiting blocks on both sides, and the front and rear ends of the limiting blocks are slidably connected with a sliding rod 13, and the two ends of the sliding rod 13 are fixedly connected to the inner wall of the mounting frame 2. By setting the sliding rod 13, the sliding stability of the vacuum suction cup 2 6 can be improved, thereby facilitating improving the sliding smoothness.

[0026] It should be noted that the utility model is a mechanical arm of a packing machine. When in use, first, when clamping an object for packing, the mechanical arm body 1 drives the vacuum suction cup 1 4 and the vacuum suction cup 2 6 to move, and the vacuum suction cup 1 4 and the vacuum suction cup 2 6 are moved to the surface of the object to suck the object, and when sucking, the push rod of the electric telescopic rod 10 can be controlled to retract and drive the support plate 9 to extend from the bottom of the connecting plate 7 to block the bottom of the vacuum suction cup 1 4 and the vacuum suction cup 2 6. The support plate 9 plays an anti-dropping role to prevent the object from falling directly due to the small suction force of the vacuum suction cup 1 4 and the vacuum suction cup 2 6;

[0027] At the same time, the push plate 11 is installed under the support plate 9 through the fixing bolt 12, so that when the robot body 1 drives the workpiece to move to the box opening position, the push plate 11 is inserted into the box body, and then the push rod of the electric telescopic rod 10 is extended to drive the push plates 11 to move away from each other and open the box opening, thereby preventing the box opening from accidentally shrinking and blocking the object;

[0028] When in use, since the vacuum suction cup 2 6 is threadedly connected to the threaded rod 5, the adjusting motor 14 can be started, and the threaded rod 5 is driven to rotate by the rotation of the shaft of the adjusting motor 14, thereby pushing the vacuum suction cup 2 6 to move. The adjusting motor 14 can be controlled to rotate forward or reverse as needed, and the vacuum suction cup 2 6 can be controlled to move away from or close to the vacuum suction cup 1 4, thereby changing the distance between the two, thereby adjusting the suction size and improving applicability.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
