Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to an industrial robot manipulator structure. Background Art

[0002] Industrial robotics is a key technology in modern manufacturing, and industrial robotic manipulators are widely used, particularly in high-intensity, highly repeatable, and high-precision operations. Existing industrial robotic manipulators typically utilize multi-degree-of-freedom motion and clamping mechanisms to grasp, transport, and assemble workpieces. However, in existing technologies, in some high-precision assembly and operation scenarios, the manipulator's movement is easily affected by external interference or inherent design flaws, resulting in positioning errors and motion deviations. This is particularly true in applications requiring multi-dimensional precision movement, where materials cannot be gripped at different locations according to their intended use, impacting the quality and efficiency of industrial production. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0005] Preferably, the edge of the chute is provided with scale lines, and a pointer is fixedly mounted on the surface of the slider, the pointer corresponding to the position of the scale lines. Here, the position of the slider can be displayed in real time and accurately, facilitating intuitive displacement control and position confirmation by the operator when adjusting the manipulator, thereby improving the accuracy and reliability of the operation.

[0006] Preferably, the vertical rod passes through the interior of the movable plate, and the movable plate is slidably connected to the surface of the vertical rod. Here, it can ensure that the movable plate moves smoothly and vertically along the vertical rod, enhance the vertical stability and control accuracy of the manipulator, reduce deviation during movement, and ensure reliable operation of the system.

[0007] Preferably, there are two sets of chutes and sliders, each symmetrically distributed on either side of the U-shaped plate. This improves the stability and uniformity of the sliders within the chutes, avoids wear or errors caused by uneven force on one side, and increases the durability and service life of the manipulator.

[0008] Preferably, the number of the vertical rods is four, and the four groups of vertical rods are evenly distributed around the surface of the movable plate. This can provide more support points, enhance the structural stability and load-bearing capacity of the movable plate, ensure that the movable plate remains balanced during movement, reduce vibration and deflection generated by the manipulator during operation, and improve working accuracy.

[0009] Preferably, a drive block is slidably connected to the interior of the fixed seat, the clamping plate is mounted at the bottom of the drive block, and a bidirectional screw is rotatably connected to the interior of the fixed seat. A driven wheel is fixedly mounted on the surface of the bidirectional screw, a second motor is fixedly mounted on the surface of the fixed seat, a driving wheel is fixedly mounted on the output end of the second motor, and a belt is connected between the driving wheel and the driven wheel. Here, the belt drives the driven wheel, which drives the bidirectional screw to rotate, thereby controlling the drive block to drive the clamping plate to open and close. This achieves flexible control of the clamping plate, enabling precise clamping and loosening actions, accommodating objects of different sizes and shapes, and improving the flexibility and adaptability of the industrial robot.

[0010] Preferably, a notch is formed on the surface of the fixing seat, and the belt is located inside the notch. Here, the belt can be effectively protected from external interference or damage, thereby improving the reliability and durability of the transmission component.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, high-precision displacement adjustment of the manipulator in the vertical direction is achieved through precise control of the cylinder. The vertical movement of the movable plate remains smooth and accurate under the guidance of the vertical pole, ensuring that no shaking or deviation occurs during operation, thereby greatly improving the movement stability of the manipulator. The rotating rod is driven to rotate by the No. 1 motor and transmitted to the connecting frame and the fixed seat through the rotating rod, further affecting the operation of the splint, which not only realizes the multi-dimensional movement of the manipulator, but also ensures that the angle and direction of the splint can be flexibly adjusted when clamping objects.

[0013] 2. In the present invention, the driving block is driven to move by a bidirectional screw, and the splint can accurately realize the opening and closing operation. The No. 2 motor drives the screw to rotate through the belt transmission system, which ensures the flexible control of the splint and enables the manipulator to accurately grasp objects of different shapes and sizes, thereby enhancing the versatility of the industrial robot, being suitable for a variety of industrial production needs, improving the flexibility of operation, and adapting to changing operational tasks.
