Description

Technical Field

[0001] This utility model belongs to the field of robotic arm suspension support technology, specifically, it relates to a multi-unit suspension bracket for modularly assembled robotic arms. Background Technology

[0002] In modern manufacturing's modular assembly workshops, modular assembly robots, with their flexibility and efficiency, have become key equipment for achieving rapid product assembly. Currently, most modular assembly robots are fixed to the ground using brackets or booms, with each robot group corresponding to an independent supporting boom. This installation method, to a certain extent, ensures the operational stability of the robot and is suitable for scenarios involving single-function robotic arms, playing a vital role in early industrial production.

[0003] However, with the increasing complexity of modular assembly processes, multiple sets of robotic arms with different functions (such as guided and assembly robotic arms) often need to work together in the workshop. Therefore, the drawbacks of individual support systems are becoming increasingly apparent: First, the one-to-one installation method of the boom occupies a large amount of floor space, resulting in a significant reduction in workbench area. The fixed supports required for robotic arm installation and the robotic arm's range of motion mutually encroach on each other's space, severely limiting the layout of workshop equipment and production efficiency. Second, since each set of robotic arms corresponds to an independent boom, the installation positions between robotic arms are relatively fixed. In the limited workshop space, the range of motion of the robotic arms is prone to overlap or blind spots, making it difficult to flexibly plan the robotic arm's operating path and failing to fully utilize the advantages of multiple sets of robotic arms working together. Third, the existing support frame mounting base design cannot meet the installation requirements of different types of robotic arms. Therefore, considering the above, the existing support structure occupies a large footprint in a limited space, limiting the operating efficiency of multiple robotic arms and affecting the versatility and scalability of the production line. Utility Model Content

[0004] In view of this, the present invention provides a multi-unit suspension bracket for modular assembly robots, which can solve the problem that the support structure occupies a large space, affecting the versatility and scalability of the robot production line.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a multi-unit suspension frame for modular assembly robotic arms, including a suspension frame. The four corners of the suspension frame are fixedly installed to the ceiling of the workshop via booms. The suspension frame includes an outer frame and a central horizontal suspension steel. The central part of the horizontal suspension steel is divided into multiple mounting sections by adjusting uprights. Each mounting section can be detachably installed with multiple sets of fixing seats. The fixing seats include vertical fixing seats and long wall-mounted fixing seats. A robotic arm mounting seat is provided at the bottom of each fixing seat.

[0007] The technical advantages of this utility model for a multi-unit suspension bracket for modular assembly robotic arms are as follows: By setting an installation frame and a suspension crossbar in the suspension bracket, and using adjusting uprights to divide the suspension crossbar into multiple installation parts, each installation part is equipped with a detachable vertical fixing seat and a long wall-mounting fixing seat, and the bottom of each part is equipped with a robotic arm mounting seat for fixed installation with the robotic arm; compared with the limitation of traditional one set of robotic arms corresponding to one supporting arm, multiple sets of robotic arms can be installed simultaneously through multiple installation parts, saving ground space; the detachable fixing seat can be flexibly installed according to the type of robotic arm, meeting the needs of different functional robotic arms, solving the problems of limited workbench area and inflexible installation of robotic arms in the prior art, and realizing the efficient layout and collaborative work of multiple robotic arms in a limited space.

[0008] Based on the above technical solution, the multi-unit suspension bracket for modular assembly robotic arms of this utility model can be further improved as follows:

[0009] The boom has reinforcing ribs on the outside, and multiple sets of expansion bolt mounting holes are opened on the outer perimeter of the boom's base plate. The mounting frame is a rectangular frame structure, which is fixedly connected by four horizontal steel bars with bolts.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the structural strength of the boom is enhanced by reinforcing ribs, making it more stable when subjected to the forces and vibrations generated during the operation of the robotic arm; and the boom is firmly connected to the ceiling by positioning and installing multiple sets of expansion anchor bolts corresponding to the expansion bolt mounting holes.

[0011] Furthermore, the two ends of the suspension crossbar are fixedly connected to the mounting frame by bolts, and a double-track groove is provided in the middle. A support rib is provided at the top of the mounting base corresponding to the position of the double-track groove.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: By opening a double-track groove in the middle and setting a support rib at the top of the mounting base corresponding to the position of the double-track groove, the double-track groove and the support rib cooperate with each other, providing precise guidance for the installation of the mounting base. At the same time, the support rib can effectively distribute the weight transmitted by the robotic arm to the suspension crossbar, reduce the local stress on the suspension crossbar, avoid structural loosening and damage caused by stress concentration, and extend the service life of the suspension crossbar.

[0013] Furthermore, the suspension crossbar is provided with multiple sets of adjusting screw holes arranged at equal intervals on both sides of the double rail groove, and the two sides of the fixing seat are fixedly installed with bolts to the corresponding adjusting screw hole positions.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting multiple sets of adjusting screw holes on both sides of the suspension cross steel, the fixed base can be fixedly installed on both sides by bolts to the corresponding adjusting screw hole positions, so as to flexibly adjust the installation position of the robotic arm according to the width requirements of different work positions.

[0015] Furthermore, the adjusting pole includes a support column, the bottom of which has a threaded channel, and the pole is connected to the inside of the threaded channel by threads. The bottom of the pole is connected to the pad.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the height of the upright can be adjusted by rotating the upright and using the threaded structure; the pads play a role in stabilizing the upright and preventing it from sliding after adjustment, and provide auxiliary support in conjunction with adjusting the upright.

[0017] Furthermore, the top of the upright is provided with an external thread structure that adapts to the threaded channel, and the bottom is fixedly connected to the pad foot, with a rubber pad at the bottom of the pad foot.

[0018] Furthermore, the two ends of the suspension crossbar are L-shaped and are fixedly connected to the mounting frame by bolts through the short side end.

[0019] Furthermore, the top of the support column is fixedly connected to the bottom of the suspension cross steel with bolts, and multiple sets of stress cables are installed between the two sides of the suspension cross steel and the long side cross steel of the outer frame.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are: by using stress cables to share the stress borne by the suspension cross steel when multiple robotic arms are working simultaneously, the force is evenly distributed to the mounting frame, reducing the deformation of the suspension cross steel and improving the stability of the overall structure.

[0021] Furthermore, the double-track groove is shaped like a dovetail groove, and the supporting rib is a dovetail block adapted to the direction of the dovetail groove.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are: the dovetail groove and the dovetail block have good guiding and anti-lateral force capabilities. Compared with the ordinary groove block structure, it can more effectively prevent the fixed seat from loosening and falling out when the robot arm is working.

[0023] Furthermore, the robotic arm mounting base of the vertical fixed base is located at its bottom end; the long wall-mounted fixed base includes an extension and a bottom mounting part, with support ribs and through holes provided on the extension, and the robotic arm mounting base located at the bottom end of the bottom mounting part.

[0024] The beneficial effects of adopting the above-mentioned improved scheme are as follows: different fixed seats can be installed according to different assembly needs; vertical fixed seats save horizontal space; long wall-mounted fixed seats can provide a longer operating radius through the design of the extension part and the bottom hanging part, which is suitable for robotic arms that require a large range of operations; by using two fixed seats with different structures in combination, more working scenarios and robotic arm installation needs are covered, solving the problem that traditional installation methods cannot meet the installation needs of different types of robotic arms, and improving the versatility and applicability of the suspension bracket.

[0025] Compared with existing technologies, the advantages of the multi-unit suspension bracket for modular assembly robotic arms provided by this utility model are as follows: the suspension bracket adopts a top-mounted method, fixing the mounting frame to the ceiling of the workshop via a boom, which significantly saves the workbench installation area compared to ground-mounted brackets; through the combination structure of the mounting frame and the suspension crossbar, combined with the multiple mounting sections separated by the adjustable uprights, multiple sets of robotic arms can be installed in a concentrated manner, optimizing the utilization of workshop space; in terms of the flexibility of robotic arm installation, the design of both vertical fixed base and long wall-mounted fixed base can adapt to the installation needs of robotic arms with different functions.
