Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology, specifically relating to a robotic arm for post-coating of barrels. Background Technology

[0002] Some products undergo off-line post-processing for barrel galvanizing, which requires multiple processes and tanks. Therefore, robotic arms are needed to replace manual labor. The compact layout can reduce labor, save costs, and improve efficiency. In existing robotic arms, after being fixed to the working position by a counterweight mounting base, the robotic arm is placed on the surface of the counterweight mounting base and secured with fixing bolts. After the bolts are fixed, the ends and bottom of the robotic arm are easily subjected to external forces during frequent post-barrel plating processing. This frequent external force can easily cause the fixing bolts to loosen and become unstable, resulting in instability of the robotic arm, reduced stability during operation, and even danger. This also affects the problem of preventing loosening and strengthening the fixation of the robotic arm during post-barrel plating processing. Therefore, this utility model proposes a robotic arm for post-barrel plating processing. Utility Model Content

[0003] The purpose of this utility model is to provide a robot for post-barrel plating processing, in order to solve the problem mentioned in the background art where the robot is fixed to the surface of the counterweight fixing seat by fixing bolts. After the bolts are fixed, the robot is prone to external force at both the end and bottom of the robot during frequent post-barrel plating processing. When the robot is frequently subjected to external force, the fixing bolts are prone to loosening and instability, which leads to instability in the operation of the robot, reduces the stability during operation, and may even cause danger.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a robot for post-coating of barrels, including a counterweight fixing base, a rotating base fixedly mounted on the upper surface of the counterweight fixing base by fixing bolts, a robot arm provided on the upper surface of the rotating base, a gripper provided at the end of the robot arm, an anti-loosening reinforcing fixing mechanism provided between the counterweight fixing base and the rotating base, and a protective mechanism provided on the end surface of the robot arm; The anti-loosening and reinforcing fixing mechanism includes a positioning and mounting assembly disposed between the bottom end of the rotating seat and the top end of the counterweight fixing seat, a rotating pressing assembly disposed at the upper surface edge of the counterweight fixing seat, and a clamping fixing assembly disposed at the bottom edge of the rotating seat. The protective mechanism includes a protective component disposed on the outer surface of the end of the robotic arm, and fixed mounting components are provided at both ends of the protective component.

[0005] Preferably, the positioning and mounting assembly includes a positioning post integrally disposed at the middle position of the upper surface of the counterweight fixing seat, and the bottom end of the rotating seat is provided with a positioning groove that matches the positioning post.

[0006] Preferably, the rotary clamping assembly includes an external threaded ring welded and fixed to the edge of the upper surface of the counterweight fixing seat, an internal threaded pressure ring being threadedly connected to the outer surface of the external threaded ring, and the inner top end of the internal threaded pressure ring pressing against the surface of the fixing bolt, and an engagement groove being formed on the surface of the internal threaded pressure ring.

[0007] Preferably, the clamping and fixing assembly includes a limiting groove formed at the bottom edge of the rotating seat, a clamping plate is limited inside the limiting groove, an arc-shaped push plate is integrally provided on the surface of the clamping plate, and an inner arc-shaped surface is formed at the inner top edge of the internal thread pressure ring.

[0008] Preferably, the inner surface of the clamping plate is in tight contact with the outer surface of the positioning post, and a return spring is fixed between the top side of the clamping plate and the end of the limiting groove.

[0009] Preferably, the protective component includes an outer flexible protective cover fitted onto the outer surface of the end of the robotic arm, with connecting rings integrally provided at both ends of the outer flexible protective cover.

[0010] Preferably, the fixed mounting assembly includes screws disposed on the surface of the connecting ring, and the end surface of the robotic arm is integrally provided with two fixing rings that are closed and installed with the connecting ring, and the surface of the fixing rings is provided with internal threaded holes that match the screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By designing an anti-loosening and reinforcing fixing mechanism, after the counterweight fixing seat and the rotating seat are fixed with bolts, when the external threaded ring rotates and the internal threaded pressure ring moves downward, the surface of the inner arc-shaped surface contacts the surface of the arc-shaped push plate, which is then pressed and moved. When the arc-shaped push plate moves, it drives the clamping plate to move within the limiting groove until it is clamped on the surface of the positioning column. After rotating into place, the top of the inner surface of the internal threaded pressure ring presses tightly against the surface of the fixing bolt. This facilitates double reinforcement installation after installation, making the robot arm more stable to operate during frequent processing after barrel plating, reducing the risk of danger, and improving the anti-loosening and reinforcing fixing of the robot arm during post-barrel plating processing.

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.

[0014] Please see Figures 1 to 4 This utility model provides a technical solution: a robot for post-processing of barrel plating, including a counterweight fixing base 101, a rotating base 102 fixedly mounted on the upper surface of the counterweight fixing base 101 by fixing bolts, a robot arm 103 provided on the upper surface of the rotating base 102, a gripper 104 provided at the end of the robot arm 103, and a PLC controller provided on the surface of the counterweight fixing base 101. The robot arm is controlled by the PLC controller. After the product is barrel-plated with zinc on the automatic line, it is unloaded into the unloading bin. The unloading bin is automatically transferred to the designated position along the track. The robot arm 103 moves to drive the gripper 104 to grab the unloading bin. According to the set PLC controller program, all post-processing is automatically completed in sequence. After processing, the robot arm pours the product out of the unloading position and unloads it into the flat oven. A loosening-resistant reinforcing fixing mechanism is provided between the counterweight fixing seat 101 and the rotating seat 102. The loosening-resistant reinforcing fixing mechanism includes a positioning and mounting component disposed between the bottom end of the rotating seat 102 and the top end of the counterweight fixing seat 101, a rotating clamping component disposed at the upper surface edge of the counterweight fixing seat 101, and a clamping fixing component disposed at the bottom edge of the rotating seat 102. When the robot is installed in the post-coating process, the loosening-resistant reinforcing fixing mechanism further reinforces and fixes the counterweight fixing seat 101 and the rotating seat 102 for stable installation and use.

[0015] To facilitate positioning and reinforcement of the counterweight fixing seat 101 and the rotating seat 102 after installation, in this embodiment, preferably, the positioning and installation component includes a positioning post 1013 integrally disposed at the middle position of the upper surface of the counterweight fixing seat 101, and a positioning groove 1014 matching the positioning post 1013 is opened at the bottom end of the rotating seat 102. After the positioning post 1013 is positioned inside the positioning groove 1014, the rotating seat 102 is fixed to the surface of the counterweight fixing seat 101, which facilitates positioning and reinforcement installation.

[0016] To facilitate rotational clamping and reinforcement installation using the rotary clamping assembly, in this embodiment, preferably, the rotary clamping assembly includes an external threaded ring 1015 welded and fixed to the edge of the upper surface of the counterweight fixing seat 101. The outer surface of the external threaded ring 1015 is threadedly connected to an internal threaded pressure ring 1011, and the inner top end of the internal threaded pressure ring 1011 presses tightly against the surface of the fixing bolt. The surface of the internal threaded pressure ring 1011 has a meshing groove 1012, which allows the internal threaded pressure ring 1011 to be rotated and lowered during reinforcement installation, thereby strengthening the fixation and stabilizing the use. Furthermore, the meshing groove 1012 allows for adjustment by using a tool to mesh the surface.

[0017] To facilitate the reinforcing installation between the counterweight fixing seat 101 and the rotating seat 102 using a clamping and fixing assembly, in this embodiment, preferably, the clamping and fixing assembly includes a limiting groove 1018 formed at the bottom edge of the rotating seat 102, a clamping plate 1019 limiting the inside of the limiting groove 1018, an integrally formed arc-shaped push plate 1017 on the surface of the clamping plate 1019, and an inner arc-shaped surface 1016 formed at the inner top edge of the internal threaded pressure ring 1011. The inner surface of the inner threaded pressure ring 1011 is in tight contact with the outer surface of the positioning post 1013. When the inner threaded pressure ring 1011 is rotated and moved down, the inner arc-shaped surface 1016 contacts the surface of the arc-shaped push plate 1017 and pushes the clamping plate 1019 to clamp it on the surface of the positioning post 1013 for reinforcement. A return spring 1010 is fixed between the top side of the clamping plate 1019 and the end of the limiting groove 1018. When disassembling without tight pressure, the clamping plate 1019 can be reset by the deformation of the return spring 1010.

[0018] The end surface of the robotic arm 103 is provided with a protective mechanism, which includes a protective component disposed on the outer surface of the end of the robotic arm 103. The two ends of the protective component are provided with fixed mounting components, which can protect the end surface of the robotic arm 103 by the protective mechanism when the robotic arm is in use, effectively preventing splashed materials, dust from falling in and being touched.

[0019] In order to facilitate the protection of the end of the robotic arm 103 by means of a protective component, and to prevent the material from splashing and the dust from falling on the end surface of the robotic arm 103 during operation, in this embodiment, preferably, the protective component includes an outer flexible protective cover 1031 that fits onto the outer surface of the end of the robotic arm 103. Both ends of the outer flexible protective cover 1031 are integrally provided with connecting rings 1033. The outer flexible protective cover 1031 is fixedly installed on the end surface of the robotic arm 103 by means of connecting rings 1033, which facilitates installation and protection, and prevents splashing materials, dust from falling in and external contact.

[0020] To facilitate the fixed installation of the fixing ring 1032 and the outer flexible protective cover 1031 using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes a screw 1034 disposed on the surface of the connecting ring 1033, and two fixing rings 1032 integrally disposed on the end surface of the robotic arm 103 to be closed and installed with the connecting ring 1033. The surface of the fixing ring 1032 is provided with an internal thread hole that matches the screw 1034. After the connecting ring 1033 is closed on the surface of the fixing ring 1032, the screw 1034 is rotated to insert into the internal thread hole for reinforcement.

[0021] The working principle and usage process of this utility model are as follows: When using this type of rotary plating post-processing robot, firstly, the counterweight fixing seat 101 is placed and fixed in the desired position. After the positioning pin 1013 engages with the positioning groove 1014, the rotating seat 102 is positioned and closed on the surface of the counterweight fixing seat 101, and the fixing bolts are rotated for reinforcement. Next, the internal thread pressure ring 1011 is rotated on the upper surface of the counterweight fixing seat 101 via the external thread ring 1015. As the internal thread pressure ring 1011 moves downwards, the inner arc-shaped surface 1016 contacts the arc-shaped push plate. The surface of 1017 presses against the arc-shaped push plate 1017 and moves. When the arc-shaped push plate 1017 moves, it drives the clamping plate 1019 to move within the limiting groove 1018 until the clamping plate 1019 is clamped on the surface of the positioning column 1013. At the same time, after rotating into place, the top of the inner surface of the internal thread pressure ring 1011 presses tightly against the surface of the fixing bolt. This facilitates more stable use after various reinforcement installations. The robot arm is more stable to operate during frequent processing after barrel plating, and is less prone to danger. It also improves the robot arm's anti-loosening and strengthening of fixation during barrel plating post-processing. Then, when the robot is in use, the outer flexible protective cover 1031 and the connecting ring 1033 are fitted together and installed on the outer surface of the robot arm 103, and the inner surface of the connecting ring 1033 contacts the outer surface of the fixing ring 1032. The rotating screw 1034 is inserted into the internal threaded hole to fix and install the outer flexible protective cover 1031 for protection. This facilitates end protection during the post-barrel plating process, preventing material splashes and dust from falling onto the end surface of the robot arm 103. At the same time, the outer flexible protective cover 1031 is made of rubber, which facilitates slight cushioning protection and is not easily damaged by contact, thus improving the convenience of end protection for the robot arm 103 during the post-barrel plating process.
