[0053] like Figure 1As shown, an embodiment of the present application provides a robotic arm 100, including the robotic arm 100, including a moving mechanism 110, a shock absorbing mechanism 120 and a clamping mechanism 130. The moving mechanism 110, the shock absorbing mechanism 120 and the clamping mechanism 130 are connected in sequence to form an independent robotic arm 100, which can be connected to any robot and cooperate with different robots to achieve different operation purposes.
[0054] When the traction robot in the related art travels on an uneven road section, the mechanical arm 100 vibrates, causing the cargo to easily come off the hook, thereby reducing the efficiency of transportation.
[0055] In view of the above problems, a shock absorbing mechanism 120 is provided, which includes a limit component 121 and a first movable component 122. The first movable component 122 is movably connected to the moving mechanism 110 so that the first movable component 122 moves relative to the moving mechanism 110 in a first direction. In this way, when the robot arm 100 drives the goods through an uneven road section, the clamping mechanism 130 can move synchronously with the material in the vertical direction to prevent the connection between the goods and the clamping mechanism 130 from being directly shaken apart and causing decoupling. In addition, the first movable component 122 is also connected to the limit component 121, and the limit component 121 is used to apply a reverse force to the movable component to reduce the movement range of the first movable component 122 in the first direction. The clamping mechanism 130 is connected to the first movable component 122. In this way, the range of movement of the connection between the goods and the clamping mechanism 130 is reduced, further reducing the occurrence of decoupling.
[0056] In one embodiment, the first movable assembly 122 includes a first fixing member 1221 , a first movable member 1222 , a first cantilever 1223 , and a second cantilever 1224 .
[0057] Please refer to Figure 1 and Figure 2 The first movable part 1222 and the first fixed part 1221 are separated from each other; one end of the first cantilever 1223 is rotatably connected to the first fixed part 1221, and the other end is rotatably connected to the first movable part 1222; the first cantilever 1223 and the second cantilever 1224 are arranged at intervals, and one end of the second cantilever 1224 is rotatably connected to the first fixed part 1221, and the other end is rotatably connected to the first movable part 1222.
[0058] It should be noted that the first direction is along the length direction of the first fixing member 1221. Generally, when the robot arm 100 is used to pull goods, the first fixing member 1221 is vertically arranged on the ground to achieve a shock absorption effect. In other embodiments, the first direction may be changed accordingly if the robot arm 100 is used for different purposes.
[0059] It should be noted that "movable parts" and "fixed parts" do not specifically refer to the parts being in a fixed state or a movable state. There is a relative motion relationship between the fixed parts and the movable parts. For example, Figure 1 The first fixed member 1221 can move along with the moving mechanism 110 , but the first fixed member 1221 is fixed relative to the first movable member 1222 , and the first movable member 1222 is movable relative to the first fixed member 1221 .
[0060] like Figure 1 As shown, the first fixing member 1221 is in a groove shape, and the first movable member 1222 is also in a groove shape. The first movable member 1222 is embedded in the first fixing member 1221 , thereby reducing the volume of the first movable component 122 .
[0061] The first movable member 1222 and the first fixed member 1221 are separated from each other, so that a structure capable of relative movement is formed between the first fixed member 1221 and the first movable member 1222 .
[0062] The first cantilever 1223 and the first fixed part 1221 are hinged via a pin, and the first cantilever 1223 and the first movable part 1222 are hinged via a pin; the second cantilever 1224 and the second fixed part 1121 are hinged via a pin, and the second cantilever 1224 and the second movable part 1122 are hinged via a pin.
[0063] like Figure 4 As shown, in this embodiment, the number of the first cantilever 1223 is two, and the two first cantilever 1223 are respectively arranged on two opposite sides of the first fixed member 1221. Correspondingly, the number of the second cantilever 1224 is two, and the two second cantilever 1224 are respectively arranged on two opposite sides of the first fixed member 1221. The first cantilever 1223 and the second cantilever 1224 are arranged at intervals along the first direction. In this way, one side of the first fixed member 1221 and the first movable member 1222 forms four active points through one first cantilever 1223 and one second cantilever 1224, and the four active points form a parallelogram.
[0064] The first cantilever 1223 and the second cantilever 1224 are of equal length, and the line between the connection point between the first cantilever 1223 and the first movable member 1222 and the connection point between the second cantilever 1224 and the first movable member 1222 is parallel to the first direction. In this way, when the first fixed member 1221 is fixed relative to the first movable member 1222, the first movable member 1222 can move back and forth along the first direction relative to the first fixed member 1221 in the event of vibration, so that the clamping mechanism 130 can move up and down synchronously with the material in the vertical direction, thereby preventing the connection point between the goods and the clamping mechanism 130 from being directly shaken apart and causing decoupling.
[0065] In other embodiments, the number of the first cantilever 1223 and the second cantilever 1224 is the same, and the number of the first cantilever 1223 can be three or more. In the actual production process, it can be increased as needed. For example, when the consigned goods are heavy, or the first fixed part 1221 and the first movable part 1222 are large in volume, the weight of the first cantilever 1223 and the second cantilever 1224 can be appropriately increased to make the connection between the first fixed part 1221 and the first movable part 1222 more stable.
[0066] In one embodiment, the limiting assembly 121 includes a baffle 1211 and a restoring member 1212 .
[0067] like Figure 2 As shown, the baffle 1211 is connected to the first fixing member 1221, and the baffle 1211 and the first movable member 1222 are spaced apart along the first direction. In this embodiment, the baffle 1211 is disposed at the bottom end of the first fixing plate 11211 to limit the lowest position of the first movable member 1222.
[0068] The reset member 1212 is an elastic member, such as a spring, an elastic sleeve, a spring sheet, or the like having an elastic structure.
[0069] The reset member 1212 connects the baffle 1211 and the first movable member 1222. Thus, when the traction robot vibrates, the reset member 1212 provides a force opposite to the moving direction of the first movable member 1222, thereby reducing the vibration amplitude of the first movable member 1222, making the traction robot's travel process smoother and further preventing the material from being decoupled from the clamping mechanism 130.
[0070] In other embodiments, the baffle 1211 can also be set at the top of the first fixed plate 11211, or the baffle 1211 can also be set at the bottom and top of the first fixed plate 11211 to limit the highest position of the activity of the first movable part 1222, or to limit the lowest position and the highest position of the activity of the first movable part 1222 at the same time, thereby reducing the vibration amplitude of the first movable part 1222, making the moving process of the traction robot smoother, and further preventing the material from being decoupled from the clamping mechanism 130.
[0071] In one embodiment, the moving mechanism 110 includes a second movable assembly 112 , and the second movable assembly 112 includes a second fixed member 1121 , a second movable member 1122 , a third cantilever 1123 , and a fourth cantilever 1124 .
[0072] like Figure 1 As shown, the second movable member 1122 and the second fixed member 1121 are spaced apart, and the first fixed member 1221 is connected to a side of the second movable member 1122 away from the second fixed member 1121 .
[0073] Specifically, the second fixing member 1121 includes a fixing plate 11211 and a connecting plate 11212 , wherein the fixing plate 11211 and the second movable member 1122 are spaced apart, and the connecting plate 11212 is connected to the fixing plate 11211 at one side of the second movable member 1122 .
[0074] It should be noted that the robot arm 100 as a whole is a mechanism that can operate independently and can be adapted to mechanisms for multiple purposes. The robot arm 100 can be connected to other mechanisms through the connecting plate 11212 to play different roles.
[0075] It should be noted that in the present application, the robot arm 100 is connected to the traction robot, so that the robot arm 100 of the present application is used to drag materials. In other embodiments, for example, the robot arm 100 can also be connected to the three-way moving mechanism 110 to achieve material transfer and feeding on the production line; for example, the robot arm 100 can also cooperate with the laser welding head, and the robot arm 100 can be used as a fixture for clamping the workpiece to be welded, etc. The robot arm 100 cooperates with mechanisms with different functions to play different roles, thereby improving the scope of application of the robot arm 100.
[0076] One end of the third cantilever 1123 is rotatably connected to the second fixed member 1121 , and the other end is rotatably connected to the second movable member 1122 . The fourth cantilever 1124 is arranged parallel to the third cantilever 1123 , and one end of the fourth cantilever 1124 is rotatably connected to the second fixed member 1121 , and the other end is rotatably connected to the second movable member 1122 .
[0077] Exemplarily, the third cantilever 1123 and the fixed plate 11211 are hinged by a pin, and the third cantilever 1123 and the second movable part 1122 are hinged by a pin; the third cantilever 1123 and the fourth cantilever 1124 are spaced apart along the first direction, the fourth cantilever 1124 and the fixed plate 11211 are hinged by a pin, and the fourth cantilever 1124 and the second movable part 1122 are hinged by a pin.
[0078] like Figure 3 As shown, in this embodiment, the connection between the third cantilever 1123, the fourth cantilever 1124, the fixed plate 11211 and the second movable member 1122 forms a parallelogram. The moving mechanism 110 also includes a first driving component 111, which is arranged in the parallelogram, making the structure of the moving mechanism 110 more compact.
[0079] The first driving assembly 111 includes a first driving member 1111 and a first telescopic rod 1112. The first driving member 1111 is connected to the second fixing member 1121; the first telescopic rod 1112 is connected to the output end of the first driving member 1111, and one end of the first telescopic rod 1112 away from the first driving member 1111 is connected to the second movable member 1122, and the first driving member 1111 drives one end of the first telescopic rod 1112 away from the first driving member 1111 to move toward or away from the second fixing member 1121, so that the second movable member 1122 moves along the first direction, and the shock absorbing mechanism 120 and the clamping mechanism 130 move along the first direction with the second movable member 1122.
[0080] Specifically, Figure 1 and Figure 3 As shown, when the end of the first telescopic rod 1112 away from the first driving member 1111 moves toward the direction close to the second fixed member 1121, the length of the first telescopic rod 1112 becomes longer, and the first movable member 1222 and the second fixed member 1121 move upward; when the end of the first telescopic rod 1112 away from the first driving member 1111 moves toward the direction away from the second fixed member 1121, the length of the first telescopic rod 1112 becomes shorter, and the first movable member 1222 and the second fixed member 1121 move downward.
[0081] It should be noted that when the first driving member 1111 is stationary, the above-mentioned parallelogram is divided into two trapezoids, and six supporting points are provided to share the weight of the goods carried on the clamping mechanism 130, so that the overall structure of the robot arm 100 is more stable and not easy to move.
[0082] It should be noted that the number of the moving mechanisms 110 can be increased.
[0083] For example, there are two moving mechanisms 110, one moving mechanism 110 is connected to the shock absorbing mechanism 120, driving the shock absorbing mechanism 120 to move along the first direction, and the movable part of the other moving mechanism 110 is connected to the fixed plate 11211, so that the moving mechanism 110 drives the other moving mechanism 110 and the shock absorbing mechanism 120 to move in a direction perpendicular to the first direction.
[0084] For example, there are three moving mechanisms 110, and the three moving mechanisms 110 and the shock absorbing mechanisms 120 are connected in sequence. The moving directions of the movable parts of the three moving mechanisms 110 are perpendicular to each other. In this way, the three moving mechanisms 110 can drive the shock absorbing mechanisms 120 to move in three directions.
[0085] In one embodiment, the clamping mechanism 130 includes a third movable component 132 and a second driving component 131 that drives the third movable component 132 to move.
[0086] The third movable assembly 132 includes a third fixing member 1321 , a third movable member 1322 , a fifth cantilever 1323 and a sixth cantilever 1324 .
[0087] like Figure 1 As shown, the third fixing member 1321 is connected to the first movable member 1222. Specifically, the third fixing member 1321 is connected to the bottom end of the first movable member 1222. The third fixing member 1321 and the first movable member 1222 are connected to form an L-shaped structure.
[0088] The third movable member 1322 is spaced apart from the third fixing member 1321 and the first movable member 1222 , respectively. The third movable member 1322 is disposed close to the bending portion of the L-shaped structure.
[0089] In one embodiment, the third movable member 1322 and the first movable member 1222 are integrally formed to improve structural strength.
[0090] The third movable member 1322 is in a groove-shaped structure, and the third movable member 1322 is opposite to the opening of the first movable member 1222 .
[0091] One end of the fifth cantilever 1323 is rotationally connected to a side of the first movable part 1222 away from the first fixed part 1221, and the other end is rotationally connected to the third movable part 1322; the sixth cantilever 1324 is spaced apart from the fifth cantilever 1323, and one end of the sixth cantilever 1324 is rotationally connected to a side of the first movable part 1222 away from the first fixed part 1221, and the other end is rotationally connected to the third movable part 1322.
[0092] The fifth cantilever 1323 and the sixth cantilever 1324 are both plate-shaped, one end of the fifth cantilever 1323 is hinged to the third movable plate through a pin, and the other end is hinged to the second movable plate through a pin, and the fifth cantilever 1323 and the sixth cantilever 1324 are spaced apart along the first direction; one end of the fifth cantilever 1323 is hinged to the third movable plate through a pin, and the other end is hinged to the second movable plate through a pin. In this way, the connection between the fifth cantilever 1323 and the first movable member 1222 and the third movable member 1322, respectively, and the connection between the sixth cantilever 1324 and the first movable member 1222 and the third movable member 1322, respectively, form a parallelogram.
[0093] The second driving assembly 131 includes a second driving member 1311 and a second telescopic rod 1312. The second driving member 1311 is hinged to the first movable member 1222; the second telescopic rod 1312 is connected to the output end of the second driving member 1311, and one end of the second telescopic rod 1312 away from the second driving member 1311 is connected to the third movable member 1322. The second driving member 1311 drives one end of the second telescopic rod 1312 away from the second driving member 1311 to move toward or away from the second movable member 1122, so that the third movable member 1322 moves toward or away from the third fixed member 1321.
[0094] In one embodiment, the clamping mechanism 130 further includes a clamping claw 1313, which is connected to a side of the third movable member 1322 away from the first movable member 1222, and moves with the third movable member 1322 toward or away from the third fixed member 1321 to clamp or release the material.
[0095] Specifically, Figure 1 and Figure 5 As shown, when the end of the second telescopic rod 1312 away from the second driving member 1311 moves toward the direction close to the first movable member 1222, the length of the second telescopic rod 1312 becomes shorter, and the clamping claw 1313 and the third fixed member 1321 are separated, thereby releasing the activity; when the end of the second telescopic rod 1312 away from the second driving member 1311 moves toward the direction away from the first movable member 1222, the length of the second telescopic rod 1312 becomes longer, and the clamping claw 1313 approaches the third fixed member 1321, thereby clamping the cargo.
[0096] Through the linkage of the above three parallelograms, the functions of lifting and lowering, clamping and releasing of materials as well as preventing unhooking can be realized.
[0097] In one embodiment, the shock absorbing mechanism 120 further includes a visual component 123. Figure 1 As shown, it is fixed above the first fixing member 1221 and is used to determine the relative position of the clamping jaw 1313 and the material so that the clamping jaw 1313 and the material can be quickly and accurately docked.
