Description

Technical Field

[0001] This utility model relates to the field of industrial machinery technology, and more specifically, to a multi-axis collaborative device for industrial robots. Background Technology

[0002] Industrial robots are key equipment for achieving automated and intelligent production in modern manufacturing. One of their core performance characteristics lies in the precision and efficiency of coordinated motion control between multiple axes. Currently, most common multi-axis industrial robots adopt serial or parallel robotic arm structures, driven by servo motors at each joint to achieve complex end-effector trajectories.

[0003] However, existing multi-axis collaborative devices still have some shortcomings: First, traditional structures often rely on complex gearboxes or linkage mechanisms, resulting in high system rigidity and inertia, making it difficult to achieve high-speed, high-precision fine-tuning motion; second, their lifting and translation functions are usually controlled independently by different drive units, resulting in poor coordination and easy accumulation of motion errors, affecting the positioning accuracy of the end effector; third, end effectors often have single functions and poor adaptability, requiring frequent tooling changes when dealing with workpieces of different shapes and sizes, reducing production efficiency.

[0004] Therefore, there is an urgent need in the field for a multi-axis collaborative device that is compact, flexible in movement, highly accurate in control, and adaptable to end effectors, in order to meet the growing demand for high-precision automated operations. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a multi-axis collaborative device for industrial robots to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A multi-axis collaborative device for an industrial robot includes a top beam, a connecting plate on the outside of the top beam, support columns at both ends of the connecting plate, a collaborative mechanism mounted on the upper surface of the top beam, a second support column on the outside of the top beam, a base plate at the bottom end of the second support column, a lifting plate slidably connected to the outside of the collaborative mechanism, a support plate on the upper surface of the lifting plate, a slider on the outside of the support plate, a guide rail slidably connected inside the slider, and the guide rail being located outside the first support column.

[0007] Preferably, to facilitate the coordinated operation of the front-end transmission, the coordinated mechanism includes a first conveyor belt, the lower surface of which is mounted on the upper surface of the top beam, the bottom end of which is located on a first connecting block, a support frame at the bottom of the first connecting block, a first motor mounted on the bottom of the first connecting block, the output end of which is connected to the first conveyor belt, a second connecting block mounted on the upper surface of the support frame, a second motor at the bottom of the second connecting block, the output end of which is connected to the second conveyor belt, the bottom of the second conveyor belt mounted on the upper surface of the top beam, and a lifting assembly at the output end of the second conveyor belt.

[0008] Preferably, to facilitate position adjustment during operation of the front end, the lifting assembly includes a screw, the top end of which is connected to the output end of the second conveyor belt, the bottom end of which is threaded into the interior of the base plate, the output end of the first conveyor belt is connected to a slide rod, the bottom end of which is located inside the base plate, a third conveyor belt is installed outside the slide rod, the outside of which is installed at the bottom of the lifting plate, and a snap-fit ​​mechanism is installed at the output end of the conveyor belt.

[0009] Preferably, in order to limit and fix the component, the snap-fit ​​mechanism includes a snap-fit ​​housing, and the interior of the snap-fit ​​housing is provided with a sliding groove.

[0010] Preferably, in order to facilitate the adjustment of the position of the sliding base, a sliding base is installed inside the sliding groove.

[0011] Preferably, a damping nut is provided inside the sliding base to facilitate disassembly and replacement of the sliding base and adjustment according to different materials.

[0012] Preferably, in order to facilitate the gripping and locking of materials, the upper surface of the sliding base is provided with a claw, and the outside of the claw is equipped with an anti-slip pad.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model organically integrates horizontal transmission with vertical lifting motion through the unique layout of the top beam, coordinating mechanism and lifting components. The drive of multiple motors is effectively transmitted through the conveyor belt and screw mechanism, realizing the composite motion of the lifting plate in multiple directions of X, Y and Z. The motion of each axis is closely coupled and has good coordination, reducing the cumulative error caused by traditional multi-independent drive systems.

[0014] 2. By incorporating a locking mechanism with grooves and a sliding base with built-in damping nuts, the position of the chuck can be flexibly adjusted and locked according to the workpiece size. The anti-slip pads on the outside of the chuck further enhance the stability and reliability when gripping different materials, enabling rapid and flexible workpiece switching and improving the versatility and production efficiency of the entire device.

Detailed Implementation

[0018] 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.

[0019] According to an embodiment of the present invention, a multi-axis collaborative device for industrial robots is provided.

[0020] like Figure 1-5As shown, a multi-axis collaborative device for an industrial robot includes a top beam 1, a connecting plate 2 on the outside of the top beam 1, and support columns 3 at both ends of the connecting plate 2. These components provide support for a collaborative mechanism 4, which can lift and rotate the terminal. A second support column 6 is located on the outside of the top beam 1, and a base plate 5 is located at the bottom of the second support column 6. These components provide bottom support and are primarily made of aluminum alloy. A lifting plate 7 is supported by the collaborative mechanism 4, and a support plate 8 is connected to the lifting plate 7 and slides on a guide rail 10 via an external slider 9. The guide rail 10 is fixed to the outside of the support column 3. The collaborative mechanism 4 includes a transmission belt 41, and the first and second transmission belts 41 and 44 are mounted on connecting blocks 42 and 45 above the top beam 1 and support frame 43. Motor 1 (46) and Motor 2 (47) are installed below for transmission. The output end of conveyor belt 2 (44) is connected to a lifting assembly, which includes a screw 48. The top end of screw 48 is connected to the output end of conveyor belt 2 (44), and the bottom end of screw 48 is threaded into the inside of the base plate 5. Screw 48 drives the lifting plate 7 to slide above the slide bar 49. Conveyor belt 1 (41) drives the lifting plate 7 to rise and fall. Conveyor belt 2 (44) drives the slide bar 49 to slide the lifting plate 7, which in turn drives the conveyor belt 3 (410) below the lifting plate 7 to rise and fall. The rotating shaft on the conveyor belt 3 (410) can slide on the slide bar 49 and can be driven by conveyor belt 2 (44) alone. Conveyor belt 3 (410) drives the locking mechanism 11 below. The controller 12 installed outside the support column 1 (3) can coordinate the operation of motor 1 (46) and motor 2 (47), thereby driving the end to rise and rotate.

[0021] like Figure 1-5 As shown, the clamping mechanism 11 includes a clamping housing 111. The bottom of the clamping housing 111 is connected to the rotating shaft of the conveyor belt 410, which drives the whole to rotate. A sliding groove 112 is provided inside the housing. The sliding base 113 is driven by external hydraulic pressure and slides inside it. The sliding speed is adjusted according to the damping nut 114. It can also be disassembled and replaced. The upper surface of the sliding base 113 is provided with a claw 115. An anti-slip pad 116 is installed on the outside of the claw 115 to prevent the clamped items from falling off during transportation.

[0022] Working principle: When this utility model is in use, the controller 12 drives the motor 46 to drive the conveyor belt 41, the conveyor belt 41 drives the screw 48 to lift the lifting plate 7, the conveyor belt 44 drives the slide bar 49 to drive the lower conveyor belt 410, and the end clamping mechanism 11 at the upper end of the conveyor belt 410 rotates, thereby realizing the lifting and rotating effect at the end.

[0023] The sliding bases 113 on both sides inside the housing 111 are moved by hydraulic drive, which drives the upper gripper 115 to clamp the material. At the same time, the gripper 115 on either side can be clamped individually by the controller 12 to achieve a coordinated clamping effect. The clamping speed and component replacement can be adjusted by the damping nut 114 on the upper side to improve practicality.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
