Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial robot technology, specifically a multi-joint manipulator for industrial robots. Background Technology
[0002] A robotic arm is an automated device that mimics certain movements and functions of a human hand and arm to grasp, move objects, or manipulate tools according to a fixed program. Its key feature is that it can be programmed to perform various pre-defined tasks, and its construction and performance combine the advantages of both humans and machines. The robotic arm was the earliest industrial robot and also the earliest modern robot. It can replace heavy human labor to achieve mechanization and automation of production, and can operate in hazardous environments to protect human safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry, and nuclear energy sectors.
[0003] Current robotic arms are installed and used in a single-joint configuration. This limitation makes it difficult to precisely adjust to a specified angle when changing direction, affecting the efficiency of processing operations. In addition, the traction-type multi-joint structure causes the front joint to rotate along with the adjustment, making it impossible to achieve single-point control and resulting in insufficient adjustment precision. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-joint manipulator for industrial robots, in order to solve the problems mentioned in the background art, where current manipulators are installed and used in a single-joint form. This makes it impossible to accurately adjust to a specified angle when adjusting the direction due to the limitation of the joint, which affects the efficiency of processing operations. At the same time, in the traction-type multi-joint structure, the adjustment is affected by the rotation of the front joint, making it impossible to form a single point control and resulting in insufficient adjustment precision.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A multi-joint manipulator for industrial robots includes a mating sleeve block. One end of the mating sleeve block is connected to a docking box. A horizontally formed slot is provided at the end of the mating sleeve block away from the docking box. A flipping link is horizontally inserted into the inner side of the slot. One end of the flipping link is welded to an end connecting plate. One end of the mating sleeve block is connected to a stabilizing plate. The stabilizing plate has evenly distributed fixing screw holes at the end away from the mating sleeve block, and an electrical connection hole at the end of the stabilizing plate away from the mating sleeve block. The connecting plate has evenly spaced connecting screw holes at the end away from the flipping connecting rod. A flipping shaft is horizontally inserted into the side of the flipping connecting rod. The inner wall of the sleeve channel has symmetrically spaced inner sleeve holes. A fixed bearing is fixedly engaged on the inner side of the inner sleeve hole. A flipping motor is embedded in the inner side of the mating block. A side engaging block is welded to the end of the mating block away from the sleeve channel. A side engaging hole is opened at one end of the docking box. A side mating groove is opened on the inner side of the docking box. A rotating motor is bolted to the inner side of the side mating groove.
[0007] In a preferred embodiment of this utility model, there are multiple mating sleeves and docking boxes, and one end of each of the multiple mating sleeves is connected to one end of the docking box. The sleeve groove is horizontally opened at one end diameter of the mating sleeve, and both ends of the sleeve groove horizontally penetrate the outer side wall of the mating sleeve and extend to the outer side in an open shape.
[0008] In a preferred embodiment of this utility model, one end of the flipping connecting rod is horizontally inserted into the center of the inner side of the sleeve groove, and the other end is horizontally welded to the center of one end of the docking box and the end connecting plate. The stable mating plate is docked at one end of the mating block away from the end connecting plate.
[0009] In a preferred embodiment of this utility model, the fixing screw holes are arranged in a ring at equal intervals on one side of the stable plate near the edge. The internal connection of the power socket is electrically connected to the flip motor and the rotation motor. The arrangement of the connecting screw holes is consistent with the arrangement of the fixing screw holes.
[0010] In a preferred embodiment of this utility model: the flipping shaft is horizontally fixedly inserted at one end of the flipping connecting rod away from the docking box and the end connecting plate, the two ends of the flipping shaft are horizontally inserted at the inner side of the fixed bearing, the flipping motor is fixedly installed at the side near the sleeve groove, and the output end is horizontally extended and welded at one end of the flipping shaft.
[0011] In a preferred embodiment of this utility model: the side locking blocks are all locked one-to-one with the inner side of the side locking holes, the output end of the rotating motor extends horizontally to the inner side of the side locking holes, and the extended end is horizontally welded to the center position of one end of the side locking block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention features a stabilizing plate with one end connected to the connecting end, secured with bolts and screw holes for a unified installation. The connector plug is inserted into the power socket to provide power. The clamping structure is also bolted to the connecting screw holes at one end of the connecting plate, completing the arm assembly. For multi-angle adjustment, the corresponding rotating motor rotates, causing the side locking block to rotate within the side locking hole, thus rotating the mating sleeve to a specified angle. Simultaneously, the rotating motor on the side rotates, causing the rotating shaft to rotate inside the fixed bearing, rotating the rotating connecting rod inside the sleeve groove to a specified angle. This allows the connecting box and the connecting plate to rotate to the specified angle, satisfying the multi-angle rotation needs of the arm. The multi-joint connection structure allows for multi-angle operation, while the individual joint control structure allows for precise control. Attached Figure Description

[0022] Please see Figure 2-5In this embodiment of the present invention, a multi-joint manipulator for an industrial robot has a connecting plate 5 with connecting screw holes 9 evenly distributed at the end away from the flipping link 4. The arrangement of the connecting screw holes 9 is consistent with the arrangement of the fixing screw holes 7. A flipping shaft 10 is horizontally inserted into the side of the flipping link 4. The inner wall of the sleeve channel 3 has symmetrically opened inner sleeve holes 11. A fixing bearing 12 is fixedly engaged on the inner side of the inner sleeve hole 11. A flipping motor 13 is embedded in the inner side of the sleeve block 1.

The clamping structure is connected to one end of the end connecting plate 5 and fixed with bolts to the connection screw holes 9 to form an integrated arm installation. When multi-angle flipping adjustment is required, the rotation of the corresponding rotation motor 17 drives the output end to drive the side locking block 14 to rotate inside the side locking hole 15, thereby driving the mating sleeve block 1 to rotate to the specified angle. At the same time, the rotation of the side flipping motor 13 drives the output end to drive the flipping shaft 10 to rotate inside the fixed bearing 12, thereby driving the flipping connecting rod 4 to flip to the specified angle inside the sleeve groove 3. This causes the docking box 2 and the end connecting plate 5 to flip to the specified angle to meet the multi-angle flipping use of the arm.
