Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm with a flipping function. Background Technology

[0002] A robotic arm is an automated device that mimics the functions of a human hand. It can perform tasks such as grasping, handling, and assembly, and is widely used in industrial automation, robotics, medical surgery, and laboratory operations. Robotic arms can perform a variety of complex operations, offering advantages in efficiency and precision. Depending on their application, robotic arms can be designed in different forms, such as humanoid robotic arms and wrist-based robotic arms.

[0003] A robotic arm device disclosed in Chinese Patent Publication No. CN211163988U utilizes multiple grippers on a support column to grasp different parts of a target object, thereby better securing the object and facilitating subsequent processing, such as in waste sorting. Different grippers grasping different parts of the same object enable division of labor and automation in object grasping. However, the robotic arm exhibits low flexibility, unable to quickly adjust the gripping angle according to actual needs, thus affecting its overall ease of use and applicability. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm with a flipping function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a robotic arm with a flipping function, comprising a mounting base, characterized in that: a moving mechanism is provided in the middle position inside the mounting base, side plates are provided on both sides of the bottom end of the moving mechanism, a rotating mechanism is provided inside the left side plate, a clamping plate is provided on one side of the side plate, an adsorption mechanism is provided on one side of the side plate, and a limiting mechanism is provided inside the right side plate.

[0006] Preferably, a hydraulic rod is installed at the middle position of the top of the mounting base, and a mounting plate is fixedly connected to the top of the hydraulic rod.

[0007] Preferably, the moving mechanism includes a first servo motor installed at the middle position on one side inside the mounting base, and a bidirectional threaded rod is installed at the output shaft end of the first servo motor. The two sides of the bidirectional threaded rod are threadedly connected to threaded blocks whose bottom ends are fixedly connected to the side plate.

[0008] Preferably, the rotating mechanism includes a second servo motor installed at the middle position of the top end inside the side plate, and a first gear is installed on the output shaft end of the second servo motor. One side of the first gear is meshed with a second gear that is fixedly connected to the clamping plate on one side.

[0009] Preferably, the adsorption mechanism includes a negative pressure pump installed on one side of the side plate, and a suction cup with one side communicating with the negative pressure pump is fixedly connected to the middle position of one side of the clamping plate.

[0010] Preferably, the limiting mechanism includes a rotating shaft rotatably connected to one side of the side plate, a positioning hole on one side of the clamping plate, a third gear fixedly connected to one side of the clamping plate, a fourth gear rotating inside the side plate meshing with one side of the third gear, a winding shaft fixedly connected to one side of the fourth gear, a pull rope fixedly connected to one side of the outer side of the winding shaft, a movable plate fixedly connected to one side of the pull rope, a positioning rod that engages with the positioning hole fixedly connected to one side of the movable plate, and a spring fixedly connected to the side of the movable plate away from the positioning rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of robotic arm with a flipping function has a rotating mechanism set on one side inside the side plate. When the two sets of side plates drive the clamping plate to clamp the workpiece, the second servo motor on the rotating mechanism can be started to rotate. At this time, the second servo motor drives the first gear to rotate, which can drive the workpiece held by the clamping plate to flip quickly through the second gear. An adsorption mechanism is set on one side of the side plate to increase the adsorption force of the clamping plate on the workpiece, thereby improving the overall functionality and ease of use of the robotic arm.

[0013] 2. This type of robotic arm with a flipping function has a limit mechanism inside the right side plate at the bottom of the mounting base. When the left clamping plate flips the clamped workpiece, the workpiece can drive the third gear on the limit mechanism to rotate through the right clamping plate. At this time, the third gear drives the winding shaft to rotate through the fourth gear, which can pull the pull rope to wind up and squeeze the spring through the movable plate. At the same time, the movable plate can drive the positioning rod to be pulled out from the positioning hole on the clamping plate. When the clamping plate is reset, due to the reaction force of the spring being squeezed, the positioning rod can be driven by the movable plate to insert into the interior of the clamping plate and quickly lock the clamping plate, ensuring the stability and safety of the robotic arm in subsequent use.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A robotic arm with a flipping function includes a mounting base 1. A moving mechanism 2 is provided in the middle of the mounting base 1. Side plates 3 are provided on both sides of the bottom end of the moving mechanism 2. A rotating mechanism 4 is provided inside the left side plate 3. A clamping plate 5 is provided on one side of the side plate 3. An adsorption mechanism 6 is provided on one side of the side plate 3. A limiting mechanism 7 is provided inside the right side plate 3.

[0022] A hydraulic rod 101 is installed at the middle position of the top of the mounting base 1. A mounting plate 102 is fixedly connected to the top of the hydraulic rod 101. The hydraulic rod 101 can push the robot arm to adjust its height. At the same time, the mounting plate 102 can facilitate the installation of the robot arm with external equipment.

[0023] The moving mechanism 2 includes a first servo motor 201 installed in the middle of one side of the mounting base 1. A bidirectional threaded rod 202 is installed on the output shaft end of the first servo motor 201. Threaded blocks 203 with their bottom ends fixedly connected to the side plates 3 are threaded on both sides of the bidirectional threaded rod 202. When the first servo motor 201 is started, it can drive the bidirectional threaded rod 202 to rotate. At this time, the threaded blocks 203 on both sides of the bidirectional threaded rod 202 can move relative to each other on the bidirectional threaded rod 202, and drive the two sets of side plates 3 at the bottom of the mounting base 1 to move relative to each other.

[0024] The rotating mechanism 4 includes a second servo motor 401 installed at the middle of the top of the side plate 3. A first gear 402 is installed on the output shaft of the second servo motor 401. A second gear 403 is meshed with one side of the first gear 402 and fixedly connected to the clamping plate 5. When the second servo motor 401 is started, it can drive the second gear 403 to rotate through the first gear 402. At this time, the second gear 403 can drive the clamping plate 5 on one side to rotate and cause the clamping plate 5 to rotate the clamped object.

[0025] The adsorption mechanism 6 includes a negative pressure pump 601 installed on one side of the side plate 3. A suction cup 602 with one side connected to the negative pressure pump 601 is fixedly connected to the middle position of one side of the clamping plate 5. When the negative pressure pump 601 is started, a negative pressure can be generated in the suction cup 602 on the clamping plate 5. At this time, the suction cup 602 can perform adsorption work on the clamped object.

[0026] Example 2 differs from Example 1 mainly in that:

[0027] A robotic arm with a flipping function includes a limiting mechanism 7 comprising a rotating shaft 301 rotatably connected to one side of a side plate 3, a positioning hole 501 on one side of a clamping plate 5, a third gear 701 fixedly connected to one side of the clamping plate 5, a fourth gear 702 meshing with one side of the third gear 701 and rotating within the side plate 3, a winding shaft 703 fixedly connected to one side of the fourth gear 702, a pull rope 704 fixedly connected to one side of the outer side of the winding shaft 703, a movable plate 705 fixedly connected to one side of the pull rope 704, a positioning rod 706 fixedly connected to one side of the movable plate 705 and engaging with the positioning hole 501, and a spring 707 fixedly connected to the side of the movable plate 705 away from the positioning rod 706. When the left clamping plate 5 is in operation... When the workpiece being clamped causes the right clamping plate 5 to rotate, the right clamping plate 5 can drive the fourth gear 702 to rotate via the third gear 701. At this time, the fourth gear 702 drives the winding shaft 703 to rotate, which can cause the winding shaft 703 to pull the pull rope 704 to wind up. At the same time, the pull rope 704 can drive the positioning rod 706 to be pulled out from the positioning hole 501 on the clamping plate 5 and squeeze the spring 707 on one side. When the clamping plate 5 is reset, due to the reaction force of the spring 707 being squeezed, the positioning rod 706 can be pushed into the positioning hole 501 on the clamping plate 5 via the movable plate 705, thus fixing the position of the clamping plate 5. Meanwhile, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] In this embodiment of the application, the position of the robot arm can be fixed by connecting the mounting plate 102 to the external equipment with bolts. At this time, the hydraulic rod 101 is activated to push the lower mounting base 1 to a suitable position. The first servo motor 201 in the mounting base 1 is activated to drive the bidirectional threaded rod 202 to rotate. At this time, the threaded blocks 203 on both sides of the bidirectional threaded rod 202 can drive the side plates 3 at the bottom to move. At the same time, the two sets of side plates 3 can perform workpiece clamping. The negative pressure pump 601 on the side plate 3 can generate negative pressure in the suction cup 602 and stably perform workpiece adsorption. At the same time, the second servo motor 401 in the side plate 3 is activated, which can drive the clamping plate 5 to rotate through the first gear 402. At this time, the clamping plate 5 can drive the clamped workpiece to flip.
