Abstract
Description
Technical Field
[0001] The present application relates to the technical field of logistics handling, and specifically to a manipulator for logistics handling. Background Art
[0002] Robots are commonly used in the cigarette manufacturing process. Robots usually use pneumatic or electric devices and have adjustable grippers to grab, move and place raw materials, finished products or semi-finished products required in the cigarette manufacturing process.
[0003] At present, the manipulators at the front end of the robotic arm are mostly fixedly installed. This type of manipulator can only grip and carry fixed types of goods. Therefore, the scope of application of the manipulator will be limited. When it is necessary to handle goods of different types or sizes, the manipulator may need to be replaced. The lack of response to various changes in the working environment can easily reduce production efficiency. Utility Model Content
[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a logistics handling robot to solve the problems existing in the prior art.
[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions:
[0006] A manipulator for logistics handling comprises a manipulator arm, to which a connecting rod is fixedly connected, a fixing frame is movably sleeved on the outer surface of the connecting rod, a plurality of groups of limiting through holes are opened on the outer surface of the connecting rod, a screw is movably penetrated on the inner side of the fixing frame, a nut is threadedly sleeved on the outer surface of the screw, an end of the fixing frame away from the connecting rod is fixedly connected to a fixing seat, and a clamping mechanism is arranged on the fixing seat.
[0007] Preferably, the clamping mechanism includes a first frame shaft fixedly connected to the outer surface of the fixed seat, and the outer surface of the first frame shaft is rotatably connected to a swing frame. The clamping mechanism can stably clamp the goods, and the rubber pad can reduce damage to the goods.
[0008] Preferably, one end of the swing frame away from the first frame shaft is rotatably connected to the second frame shaft, and the outer surface of the second frame shaft is rotatably connected to mechanical claws, and the mechanical claws are designed to have three groups and are symmetrically distributed around the periphery of the fixed base.
[0009] Preferably, a rubber pad is provided at the bottom end of the mechanical claw, and the cross-sectional shape of the rubber pad is an arc-shaped design.
[0010] Preferably, an electric push rod is fixedly installed inside the fixing seat, an output end of the electric push rod is fixedly connected to a tripod, and an outer surface of the tripod is slidably connected to an inner surface of the fixing seat.
[0011] Preferably, an end shaft is fixedly connected to the end of the tripod, and the outer surface of the end shaft is rotatably connected to the top of the mechanical claw.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The logistics handling manipulator passes the screws through the fixing frame into different limit holes, and the screws are tightened with the nuts. The position of the mechanical claw can be adjusted or different types of manipulators can be replaced, so that the manipulator can handle goods of different sizes, shapes and types, thereby expanding its scope of application and improving its flexibility and applicability.
[0014] 2.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] See also Figure 1-4A logistics handling robot comprises a robot arm 1, to which a connecting rod 2 is fixedly connected, a fixing frame 3 is movably sleeved on the outer surface of the connecting rod 2, a plurality of groups of limiting through holes 4 are opened on the outer surface of the connecting rod 2, a screw 5 is movably penetrated on the inner side of the fixing frame 3, a nut 6 is threadedly sleeved on the outer surface of the screw 5, and a fixing seat 7 is fixedly connected to one end of the fixing frame 3 away from the connecting rod 2, and a clamping mechanism is arranged on the fixing seat 7.
[0023] Through the above technical solution, the manipulator can stably clamp columnar goods of different diameters through the clamping mechanism during use. When clamping goods of different types or at different positions, the position of the mechanical claw 11 can be adjusted, or different types of mechanical claws 11 can be directly replaced.
[0024] Specifically, the clamping mechanism includes a first frame shaft 8 fixedly connected to the outer surface of the fixing seat 7, and the outer surface of the first frame shaft 8 is rotatably connected to a swing frame 9.
[0025] Through the above technical solution, three groups of swing frames 9 are provided, which can drive the mechanical claws 11 at corresponding positions through the first frame shaft 8 respectively.
[0026] Specifically, one end of the swing frame 9 away from the first frame shaft 8 is rotatably connected to the second frame shaft 10 , and the outer surface of the second frame shaft 10 is rotatably connected to the mechanical claw 11 .
[0027] Through the above technical solution, the opening and closing angle of the mechanical claw 11 can be adjusted during the deflection along the second frame axis 10.
[0028] Specifically, a rubber pad 12 is provided at the bottom end of the mechanical claw 11 , and the cross-sectional shape of the rubber pad 12 is an arc-shaped design.
[0029] Through the above technical solution, the arc-shaped rubber pad 12 is designed to match the columnar cargo and improve the stability of clamping.
[0030] Specifically, an electric push rod 13 is fixedly installed inside the fixing seat 7 , an output end of the electric push rod 13 is fixedly connected to a tripod 14 , and an outer surface of the tripod 14 is slidably connected to an inner surface of the fixing seat 7 .
[0031] Through the above technical solution, when the electric push rod 13 pushes the tripod 14 to move, the mechanical claw 11 will move up and down through the end shaft 15.
[0032] Specifically, an end shaft 15 is fixedly connected to the end of the tripod 14 , and an outer surface of the end shaft 15 is rotatably connected to the top of the mechanical claw 11 .
[0033] Through the above technical solution, the mechanical claws 11 will be relatively limited by the swing frame 9 during the up and down movement, so that the mechanical claws 11 can rotate along the end shaft 15 to adjust the opening and closing degree of the three groups of mechanical claws 11.
[0034] Working principle: When the device is clamping the goods, the electric push rod 13 can be turned on to drive the tripod 14 to move. During this process, the tripod 14 can push the mechanical claw 11 to gradually move downward through the end shaft 15. During the downward movement of the mechanical claw 11, it will rotate along the second frame axis 10, and the swing frame 9 will be deflected through the second frame axis 10. During the rotation of the swing frame 9 along the first frame axis 8, it will pull the mechanical claw 11 through the second frame axis 10, thereby changing the opening and closing degree of the mechanical claw 11, so that the bottom ends of the three groups of mechanical claws 11 gradually move closer until they cooperate with the arc-shaped rubber pad 12 to stably clamp the goods. The arc-shaped rubber pad 12 here can effectively reduce the wear caused to it when clamping the goods, and the clamping mechanism can clamp columnar goods of different diameters within a certain range, and when it is necessary to clamp goods at different positions or handle different types of goods. When the object is being picked up, the position of the mechanical claw 11 can be adjusted, or it can be directly replaced. At this time, it is only necessary to unscrew the nut 6 from the screw 5 and pull out the screw 5, and the fixing frame 3 can be directly pulled out from the connecting rod 2, so as to replace different types of manipulators, or move the fixing frame 3 to slide along the connecting rod 2, so as to move the screw 5 perforation on the fixing frame 3 to different limiting perforations 4, and then reinsert the screw 5 into the limiting perforations 4, and finally turn the knob nut 6 to tighten the screw 5, so as to complete the adjustment of the position of the fixing frame 3, that is, adjust the position of the mechanical claw 11, so that it can clamp the goods at different distances. It becomes easier to adjust the position of the mechanical claw 11 or replace different types of manipulators, so that the mechanical arm 1 can handle goods of different sizes, shapes and types, thereby expanding its scope of application and improving its flexibility and applicability.
[0035] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
