Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, and particularly relates to a handling fixture for an industrial robot. Background Technique

[0002] At present, on the assembly lines of some production workshops, industrial robots are often used to replace manual labor. This can not only save a large amount of labor, but also the industrial robots have high working efficiency during operation and can reduce the occurrence of safety accidents. Industrial robots need to use [a certain device] when clamping workpieces;

[0003] Among them, a handling fixture for an industrial robot proposed in the prior art with the authorization announcement number CN215149234U includes a connecting rod. A connecting plate is installed at the bottom end of the connecting rod. A first electric push rod is installed at the bottom of the connecting plate. A flat plate is installed at the bottom end of the first electric push rod. A cross plate is installed at the bottom of the flat plate. Clamping arms are hinged on both the left and right sides of the bottom of the cross plate. A plurality of clamping mechanisms are arranged on the side where the two clamping arms are close to each other. Mounting plates are installed on both the left and right sides of the bottom of the flat plate. Second electric push rods are hinged on the side where the two mounting plates are close to each other. The end of the second electric push rod away from the mounting plate is hinged to the clamping arm. The clamping mechanism includes a connecting block, a spring, and a pushing block;

[0004] The current grasping machine is prone to insecure fixation when grasping objects with relatively smooth surfaces. During the handling of heavier objects, the object will move downward due to gravity. There is no lifting device below the grasping device, which is likely to cause the object to fall under the action of gravity. For this reason, we propose a handling fixture for an industrial robot. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a handling fixture for an industrial robot, which can grasp objects with relatively smooth surfaces and prevent heavier objects from falling under the action of gravity through a rotatable lifting device during the object handling process, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A handling fixture for an industrial robot includes a mounting frame, a moving unit, a clamping and fixing unit, and a flipping and lifting unit;

[0007] Mounting frame: A moving unit is installed at the lower end;

[0008] Moving unit: It includes a limit support column, a first threaded rod, a first motor, and a mounting plate. The rear end inside the mounting frame is fixedly connected to the limit support column. The front end inside the mounting frame is rotatably connected to the first threaded rod. The left end of the mounting frame is fixedly connected to the first motor. The output shaft of the first motor is fixedly connected to one end of the first threaded rod. Two mounting plates are slidably connected to the outside of the limit support column. The upper end of the mounting plate is threadedly connected to the first threaded rod;

[0009] Clamping and fixing unit: Installed on the moving unit;

[0010] Flipping and lifting unit: Installed on the clamping and fixing unit and the mounting frame.

[0011] The first motor drives the first threaded rod to rotate. The rotation of the first threaded rod drives the mounting plates to move towards each other, so as to achieve the purpose of clamping and fixing the article. The limit support column plays a role in supporting the mounting plate and the heavy object below.

[0012] Furthermore, the clamping and fixing unit includes a limit frame, a fixing plate, and an anti-slip sticker. The lower end of the mounting plate is fixedly connected to the limit frame. The front and rear ends inside the limit frame are slidably connected to the fixing plate. The inside of the fixing plate is fixedly connected to the anti-slip sticker. The limit frame limits the fixing plate. The fixing plate fixes the object. The anti-slip sticker prevents the object from sliding down due to gravity when being fixed, achieving the purpose of anti-slip.

[0013] Furthermore, the clamping and fixing unit also includes a threaded rod, a first pulley, a rotating shaft, a second pulley, and a belt. One end of two threaded rods is rotatably connected to the front and rear ends inside the limit frame. The threaded rod is threadedly connected to the fixing plate. The other end of the threaded rod is fixedly connected to the first pulley. The middle of the mounting plate is rotatably connected to the rotating shaft. The two ends of the rotating shaft are fixedly connected to the second pulley. The first pulley and the second pulley are connected by the belt. The rotating shaft drives the second pulley to rotate. The belt connects the first pulley, so that the fixing plates at both ends can move towards the middle at the same time, so as to achieve the fixation and grasping of the object.

[0014] Furthermore, the clamping and fixing unit also includes a second motor and a motor fixing plate. The rear end of the limit frame is fixedly connected to the motor fixing plate. The upper end of the motor fixing plate is fixedly connected to the second motor. The output shaft of the second motor is fixedly connected to a first pulley. The motor fixing plate fixes the second motor. The second motor provides power for the fixing device.

[0015] Furthermore, the flipping and lifting unit includes a suction cup fixing box, rubber suction cups, a delivery pipe, and a vacuum machine. In the middle of the outer side of the limiting frame, there is a fixed connection with the suction cup fixing box. The suction port of the suction cup fixing box is fixedly connected with a plurality of rubber suction cups. At the upper left and right ends of the mounting frame, there are two fixed connections with vacuum machines. The air inlet of the vacuum machine is fixedly connected with one end of the delivery pipe, and the other end of the delivery pipe is fixedly connected with the air outlet of the suction cup fixing box. When handling an object with a relatively smooth surface, the rubber suction cups are in contact with the smooth surface. Air is transported through the suction cup fixing box and the delivery pipe, and air is extracted through the vacuum machine, thereby creating a vacuum between the rubber suction cups and the object surface, so as to achieve the adsorption effect and prevent the object from sliding down.

[0016] Furthermore, the flipping and lifting unit further includes a motor three, a rotating shaft, a lifting plate, and two rotating shafts are fixedly connected to the lower end of the limiting frame. The lifting plate is fixedly connected to the outside of the rotating shaft. The lower end of the motor fixing plate is fixedly connected with a motor three, and the output shaft of the motor three is fixedly connected with the rotating shaft. The motor three drives the rotating shaft to rotate, and the rotating shaft drives the lifting plate to rotate. When grasping an object, the lifting plate rotates outward, and after grasping the object, the lifting plate rotates inward, so as to lift the object from below, thereby achieving the purpose of preventing the object from falling.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This handling fixture for industrial robots has the following advantages:

[0018] 1. This handling fixture for industrial robots can grasp an object with a relatively smooth surface. The rubber suction cups are in contact with the smooth surface. Air is transported through the suction cup fixing box and the delivery pipe, and air is extracted through the vacuum machine, thereby creating a vacuum between the rubber suction cups and the object surface, so as to achieve the adsorption effect and prevent the object from sliding down.

[0019] 2. After this handling fixture for industrial robots grasps an object, the lifting plate rotates inward, so as to lift the object from below, thereby achieving the purpose of preventing the object from falling. During the object handling process, through the flippable lifting device, it is possible to prevent a heavier object from falling under the action of gravity. BRIEF DESCRIPTION OF THE DRAWINGS
