Description

Technical Field

[0001] The utility model relates to the field of robot trusses, in particular to a robot linkage truss. Background Art

[0002] A robot-linked truss refers to a system that enables the robot to move and operate on a truss by combining the robot with the truss structure. This system can improve the robot's working range and flexibility and is suitable for scenarios where the robot needs to operate in different positions.

[0003] In order to facilitate the robot to work better, it is necessary to use a robot linkage truss to facilitate the movement of the robot. For example, the prior art Chinese patent announcement number "CN218802250U" discloses a truss robot that can be quickly positioned, including two supporting columns and a truss robot body. The truss robot body is correspondingly assembled on the top of the two supporting columns, and a moving component is hidden and installed at the bottom of the two supporting columns. A monitoring component is installed on the truss robot body, and the manipulator moving position of the truss robot body can be monitored and positioned in real time with the help of the monitoring component. The utility model facilitates the subsequent rapid displacement of the truss robot body with the help of the moving component, and can realize the rapid positioning operation of the truss robot body, saving time and labor, and does not require large-scale lifting equipment for lifting and moving. In addition, the moving position of the truss robot body can be dynamically monitored with the help of the monitoring component, and the real-time positioning monitoring of the handling position can be realized, which can play an auxiliary role in the overall handling work, ensure the safety and stability of the overall handling action, and avoid the problem of accidental collision.

[0004] Some robot linkage trusses are provided with a set of universal wheels at the bottom of the truss, and the universal wheels are used to move the truss under the action of the cylinder to adjust the truss height. However, in actual operation, considering that the bottom of a similar truss is only moved by a set of parallel universal wheels, when moving the truss, if the truss height is too high or the weight of the robot is too large, it may cause the center of gravity of the truss to be unstable and lose balance, resulting in accidents and poor practicality.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5A robot linkage truss comprises a frame 1, the top of the frame 1 is slidably connected with a mounting plate 3 through a driving assembly 2, a robot 5 for transferring goods is arranged on the top of the mounting plate 3 through a cylinder 4, a reinforcing rod 6 is fixedly mounted on the lower end of the frame 1, and a moving part 8 is arranged inside the bottom thereof through an adjusting assembly 7, the adjusting assembly 7 is used to adjust the height of the frame 1, and the moving part 8 is used to move the frame 1, the height of the frame 1 is changed by the adjusting assembly 7, and the frame 1 is moved in cooperation with the moving part 8, so that it is convenient to change the position of the truss, and the robot can be quickly transferred to facilitate operations in multiple positions.

[0022] Furthermore, the driving assembly 2 includes a pair of rotating seats 21 fixedly installed on one side of the top of the frame 1, wherein a first motor 22 is fixedly installed on the side of one of the rotating seats 21, the shaft end of the first motor 22 is rotatably connected to the rotating seat 21, and a synchronous belt 23 is sleeved between the shaft end of the first motor 22 and the other rotating seat 21.

[0023] Furthermore, a round rod 25 is fixedly mounted on the other side of the top of the frame 1 through a pair of support plates 24, one side of the mounting plate 3 is fixedly connected to one side of the synchronous belt 23 through a fixing seat 26, and the other side thereof is slidably connected to the round rod 25.

[0024] In detail, the round rod 25 fixes one side of the mounting plate 3, and the fixing seat 26 cooperates with the synchronous belt 23 to fix the other side of the mounting plate 3, and then the robot 5 is driven to move by the synchronous belt 23 under the drive of the first motor 22.

[0025] In more detail, the adjustment assembly 7 includes a movable block 71, the frame 1 is composed of a plurality of support rods 11 arranged side by side, the reinforcing rod 6 is fixedly installed between the lower ends of the support rods 11 on adjacent sides, the movable block 71 is fixedly installed at the bottom of the support rod 11, and a screw rod 72 is threadedly connected at its center point, and the moving part 8 includes a universal wheel 73 fixedly installed at the bottom of the screw rod 72.

[0026] It should be added that the reinforcing rod 6 is used to improve the stability of the frame 1 on the one hand, and to protect the first connecting rod 75 and the second connecting rod 78 on the other hand, to prevent damage caused by external factors;

[0027] In addition, a plurality of feet 12 are provided at the bottom of the support rod 11, and anti-slip pads are provided at the bottom of the feet 12. When the frame 1 is lowered, the feet 12 will come into contact with the ground and stick to it, thereby preventing the universal wheel 73 from contacting the ground and moving at will. After that, when the frame 1 is raised, the feet 12 do not contact the ground, and the universal wheel 73 contacts the ground and can move.

[0028] In general, a first driven bevel gear 74 is fixedly installed on the top of the screw rod 72, and a first connecting rod 75 is rotatably connected between the laterally adjacent support rods 11 through the reinforcing rod 6. Both ends of the first connecting rod 75 are located in the support rod 11 and are fixedly installed with a second driven bevel gear 76. The second driven bevel gear 76 meshes and rotates with one side of the first driven bevel gear 74.

[0029] Specifically, when the first driven bevel gear 74 is driven by the active bevel gear 79 to rotate, it will drive the second driven bevel gear 76 to rotate. At this time, one end of the first connecting rod 75 is driven to drive the second driven bevel gear 76 at the other end to rotate. At the same time as the first driven bevel gear 74 rotates, it will drive the screw rod 72 to cooperate with the movable block 71 to drive the support rod 11 to rise or fall, so that the first connecting rod 75 can be used to synchronously adjust the height of the laterally arranged support rods 11.

[0030] Finally, a second motor 77 is fixedly installed on the side of one of the support rods 11 on the outermost side, and a second connecting rod 78 is rotatably connected between the support rod 11 and another longitudinally adjacent support rod 11 through the reinforcing rod 6. The shaft end of the second motor 77 passes through the support rod 11 and is fixedly connected to the second connecting rod 78. Driving bevel gears 79 are fixedly installed at both ends of the second connecting rod 78, and the driving bevel gear 79 meshes and rotates with the other side of the first driven bevel gear 74.

[0031] The specific operation is to use the second motor 77 to drive the second connecting rod 78 to drive the active bevel gear 79 to rotate. The function of the active bevel gear 79 is to drive the first driven bevel gear 74 and the second driven bevel gear 76 to rotate, so that the first connecting rod 75 and the second connecting rod 78 can rotate at the same time. The second connecting rod 78 is used to provide driving force for the adjustment component 7 in the longitudinally arranged support rod 11 and rotate the screw rod 72, so as to achieve the function of adjusting the overall height of the frame 1.

[0032] Working mode: When working, the first motor 22 drives the synchronous belt 23 to cooperate with the round rod 25 to drive the robot 5 to move and clamp the goods. When the position of the truss needs to be changed, the second motor 77 drives the second connecting rod 78 to drive the active bevel gear 79 to rotate. While the active bevel gear 79 rotates, it will also drive the first driven bevel gear 74 and the second driven bevel gear 76 to drive the screw rod 72 and the first connecting rod 75 to rotate synchronously. The first connecting rod 75 and the second connecting rod 78 are used to make the horizontal and longitudinal support rods 11 rise and fall synchronously, so as to achieve the purpose of adjusting the height of the frame 1.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
