Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a bionic robotic arm for loading and unloading raw materials. Background Technology

[0002] Bionic robotic arms are high-tech products that combine biomechanics and mechatronics. They are designed to simulate the motor function and sensory capabilities of the human arm, providing a near-natural arm alternative for amputees or patients with motor dysfunction.

[0003] The prior art, disclosed in publication number CN211890860U, describes a bionic robotic arm for loading and unloading materials. Addressing the problem of poor stability in existing bionic robotic arms, which are prone to damage or tipping during material loading and unloading, thus reducing work efficiency, the following solution is proposed: It includes a base with a fixing groove at its top. A rotating seat is rotatably mounted within the fixing groove. A fixing hole is formed on one side of the rotating seat, and a rotating plate is rotatably mounted within the fixing hole. A lifting rod is rotatably mounted at the bottom of the rotating plate, and a hanging plate is welded to the bottom end of the lifting rod. A second thread guide wheel is rotatably mounted on one side of the rotating plate. A fixed seat is fixedly mounted on the top of the rotating seat, and a first thread guide wheel is rotatably mounted on the top of the fixed seat. This utility model has a reasonable structure, is easy to operate, and provides good stability, reducing the risk of damage or tipping during material loading and unloading, thereby improving work efficiency.

[0004] The above-mentioned loading and unloading operations of raw materials are carried out by lifting rods and lifting platforms. However, when transporting raw materials by lifting platforms, no clamping device is set up. During transportation, the raw materials on the lifting platforms are prone to falling off the platforms, causing them to collide with the ground and thus damaging the raw materials.

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.

[0030] Please see Figure 1-6 The present invention provides the following technical solution:

[0031] A bionic robotic arm for loading and unloading raw materials includes a clamp 1 and a robotic arm 2. The bottom end of the robotic arm 2 is equipped with a base 3, and the robotic arm 2 is mounted at the middle position of the top of the clamp 1.

[0032] The clamp 1 includes a connector 11, a clamping device 12 is welded to the bottom surface of the connector 11, and adjustment components 13 are installed at the left and right ends of the clamping device 12.

[0033] The clamping device 12 includes a metal horizontal plate 121, and a fixed threaded rod 122 is welded to the top surface of the metal horizontal plate 121. The top of the fixed threaded rod 122 is movably connected to a limit cover plate 123.

[0034] The adjustment assembly 13 includes an adjustment housing 131, which is movably connected to the surface of the fixed threaded rod 122 and to the top surface of the metal cross plate 121. A nut is rotated on the surface of the fixed threaded rod 122, and the nut and the fixed threaded rod 122 lock the limiting cover plate 123 and the adjustment housing 131 together.

[0035] An adjusting screw 135 is inserted into the middle position of the adjusting housing 131. A metal lug 132 is welded to the bottom end of the adjusting housing 131. A threaded rod 133 is welded to the bottom surface of the adjusting housing 131. A synchronous motor 134 is bolted to the front of the adjusting screw 135. The synchronous motor 134 is bolted to the front of the adjusting housing 131. The output end of the synchronous motor 134 drives the adjusting screw 135 to rotate, which can adjust the position of the clamping plate 136. There are two synchronous motors 134. The two synchronous motors 134 are controlled by a PLC controller so that the output ends of the two synchronous motors 134 rotate together.

[0036] The synchronous motor 134 is threadedly connected to an adjusting threaded sleeve 137. The bottom end of the adjusting threaded sleeve 137 is movably connected to a metal lug 138. The metal lug 138 is movably connected to the bottom surface of the metal horizontal plate 121. The clamping plate 136 is movably connected to the bottom surface of the metal horizontal plate 121. The clamping plate 136 slides on the bottom surface of the metal horizontal plate 121, and the raw material is clamped and fixed by means of the clamping plate 136.

[0037] The inner surface of the metal ear 138 is welded with a clamp 136, which is usually equipped with anti-slip texture and rubber pad.

[0038] The adjusting threaded sleeve 137 includes a first threaded sleeve 1371. Limiting rods 1374 are welded to the left and right ends of the first threaded sleeve 1371. A second threaded sleeve 1372 is movably connected to the surface of the first threaded sleeve 1371. The second threaded sleeve 1372 is slidably connected to the inner wall surface of the adjusting housing 131. The first threaded sleeve 1371 is slidably connected to the inner wall surface of the adjusting housing 131. The first threaded sleeve 1371 is movably connected to the bottom surface of the limiting cover plate 123. The second threaded sleeve 1372 is threadedly connected to the surface of the adjusting screw 135. The adjusting screw 135 drives the first threaded sleeve 1371 and the second threaded sleeve 1372 to move, so as to facilitate the adjustment of the position of the clamping plate 136.

[0039] The bottom surface of the threaded sleeve 1372 is welded with a threaded rod 1373. The metal lugs 138 are divided into two groups, with two pieces in each group. The two pieces of metal lugs 138 in the same group are threadedly connected to the surface of the threaded rod 133. The threaded rod 133 and the threaded rod 1373 lock and fix the metal lugs 138 together, thereby determining the position of the clamping plate 136. The threaded rod 1373 is inserted into the outward end of the metal lug 138. The nut rotates on the surface of the threaded rod 1373 to lock and fix the threaded rod 1373 and the metal lug 138 together, thereby determining the position of the clamping plate 136.

[0040] When in use, start the synchronous motor 134. The output end of the synchronous motor 134 drives the threaded sleeves 1371 and 1327 to move, which in turn drives the threaded rod 1373 to move.

[0041] The adjusting housing 131 and the threaded sleeve 1372 slide on the inner wall surface of the adjusting housing 131. The threaded sleeve 1372 moves through the threaded rod 1373. The threaded rod 1373 drives the clamping plate 136 to slide on the bottom surface of the metal plate 121 through the metal lug 138.

[0042] Threaded sleeve 1371 and threaded sleeve 2 1372 slide on the inner wall surface of the adjusting housing 131, while the limiting cover 123 slides on the top surface of threaded sleeve 1371. The adjusting housing 131 and the base 3 limit the threaded sleeve 1371 and threaded sleeve 2 1372, protecting the safety of threaded sleeve 1371 and threaded sleeve 2 1372.

[0043] The clamping plate 136 clamps and fixes the raw material. At this time, the robotic arm 2 drives the clamping device 12 to move through the connector 11. The clamping device 12 and the clamping plate 136 transport the raw material.
