Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a material loading robot. Background Technology

[0002] In modern industrial production, especially in assembly, packaging, and machine tool loading and unloading, robotic arms are widely used to replace manual labor in repetitive grasping, moving, and placing tasks, thereby improving production efficiency and consistency. Existing loading robotic arms have some shortcomings: for example, they are complex in structure and have high manufacturing costs; or they have limited degrees of freedom of movement and insufficient positioning accuracy, making it difficult to adapt to precise loading position requirements; furthermore, their gripping mechanisms are often inconvenient to adjust and cannot quickly adapt to workpieces of different sizes or shapes. Therefore, there is an urgent need for a robotic arm that is compact, flexible in movement, precise in positioning, and has an adjustable gripping range to solve these problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a feeding robot with a simple structure and stable operation.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a loading robot, including a mounting base with a accommodating cavity, a rotating shaft pivotally connected to the mounting base, a motor fixed outside the mounting base and connected to one end of the rotating shaft, a first mounting plate on the rotating shaft, a lifting cylinder on the first mounting plate, a second mounting plate connected to the telescopic rod of the lifting cylinder, a clamping cylinder on the second mounting plate, and a clamping arm connected to the clamping cylinder. The principle of this utility model is as follows: During operation, the motor drives the rotating shaft and the first mounting plate to rotate, causing the clamping arm to rotate above the conveyor belt; then, the lifting cylinder actuates, pushing the second mounting plate and the clamping arm downwards; next, the clamping cylinder actuates, driving the two clamping arms to move towards each other to clamp the workpiece; after that, the lifting cylinder retracts, lifting the workpiece, and the motor drives the rotating shaft to rotate again, transferring the workpiece above the target workstation; finally, the lifting cylinder extends again, the clamping cylinder releases, and the workpiece is placed in the target position, completing one loading cycle.

[0005] As an improvement, the second mounting plate is located on one side of the first mounting plate, and a third mounting plate is provided on the other side of the first mounting plate. The first mounting plate, the second mounting plate, and the third mounting plate are arranged parallel to each other. A support sleeve is provided between the third mounting plate and the first mounting plate, and a guide post is provided on the second mounting plate that slides with the support sleeve.

[0006] As an improvement, the clamping arm includes a connecting part and a clamping part, which are perpendicular to each other. One end of the connecting part is connected to the clamping cylinder, and the other end of the connecting part is provided with an elongated hole. One end of the clamping part is locked to the connecting part by a bolt.

[0007] As an improvement, the first mounting plate is connected to the rotating shaft by bolts.

[0008] As an improvement, the mounting base includes two opposing upright plates, a skin plate disposed on the top and one side between the two upright plates, and a mounting ear disposed on the outer side of the lower end of the upright plates.

[0009] As an improvement, the loading robot is positioned above one end of the conveyor belt.

[0010] The beneficial effects of this utility model compared with the prior art are: 1. Compact structure and high integration: The three motion units of rotation, lifting and clamping are modularly integrated into a single mounting base, resulting in a compact structure and small footprint; 2. Smooth movement and precise positioning: By setting up a guiding mechanism consisting of a support sleeve and a guide column, the stability of the second mounting plate during the lifting process is effectively guaranteed, preventing rotation and swaying, and greatly improving the positioning accuracy of gripping and placement. 3. Easy to adjust and widely applicable: The clamping arms adopt a split design and are connected through elongated holes, which can easily adjust the extension length of the clamping part or the relative distance between the two clamping arms, thereby quickly adapting to workpieces of different sizes and having strong versatility.

[0013] Figure 3 This is a bottom view of the robotic arm. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, a loading robot is typically installed above one end of a conveyor belt 12 to pick up workpieces from the conveyor belt 12 and transfer them to the next work station.

[0016] like Figures 1 to 3 As shown, the core support structure of the robotic arm is the mounting base 1, which consists of two relatively parallel upright plates 101, a skin plate 102 connecting the top and one side of the two upright plates 101, and a mounting ear 103 located on the outer side of the lower end of the upright plates 101. The skin plate 102 serves a protective and aesthetic purpose, while the mounting ear 103 has through holes for fixing the entire robotic arm in place with bolts. A cavity is formed between the two upright plates 101.

[0017] like Figures 1 to 3As shown, the rotating shaft 2 is pivotally connected between two upright plates 101 via bearings. The motor 3 is fixed to the outside of one of the upright plates 101 by a bracket, and its output shaft is connected to one end of the rotating shaft 2 via a coupling to drive the rotating shaft 2 to rotate in both directions.

[0018] like Figures 1 to 3 As shown, the first mounting plate 4 is fixedly mounted on the rotating shaft 2 by bolts and rotates together with the rotating shaft 2, thereby realizing the horizontal rotational movement of the robot arm. A lifting cylinder 5 is mounted on one side of the first mounting plate 4, and the telescopic rod of the lifting cylinder 5 extends downward and connects to the second mounting plate 6.

[0019] like Figures 1 to 3 As shown, to ensure that the second mounting plate 6 does not rotate or wobble during lifting, a third mounting plate 9 is bolted to the other side of the first mounting plate 4. The first mounting plate 4, the second mounting plate 6, and the third mounting plate 9 are parallel to each other. At least one support sleeve 10 is fixed between the third mounting plate 9 and the first mounting plate 4. Correspondingly, a number of guide posts 11 equal to the number of support sleeves 10 are fixed on the second mounting plate 6. The guide posts 11 are inserted vertically upward into the support sleeves 10 and can slide smoothly up and down along their inner holes. This guiding mechanism ensures the straightness and stability of the lifting movement.

[0020] like Figures 1 to 3 As shown, a clamping cylinder 7 is mounted on the second mounting plate 6, and a clamping arm 8 is connected to the piston rod of the clamping cylinder 7. The clamping arm 8 consists of a connecting part 801 and a clamping part 802, which are perpendicular to each other and form an L-shape. The upper end of the connecting part 801 is connected to the clamping cylinder 7, and the lower end has an elongated hole 803. One end of the clamping part 802 is bolted to the connecting part 801 through the elongated hole 803 and locked. By loosening the bolt 804, the position of the clamping part 802 within the range of the elongated hole 803 can be adjusted, thereby changing the position of the clamping point or the opening distance between the two symmetrically arranged clamping arms 8 to accommodate workpieces of different sizes. After adjustment, tightening the bolt 804 will fix it in place.

[0021] During operation, motor 3 drives shaft 2 and first mounting plate 4 to rotate, causing clamping arm 8 to rotate above conveyor belt 12. Then, lifting cylinder 5 actuates, pushing second mounting plate 6 and clamping arm 8 downwards until clamping part 802 reaches both sides of the workpiece. Next, clamping cylinder 7 actuates, driving the two clamping arms 8 to move towards each other to clamp the workpiece. Afterwards, lifting cylinder 5 retracts, lifting the workpiece, and motor 3 drives shaft 2 to rotate again, moving the workpiece above the target station. Finally, lifting cylinder 5 extends again, clamping cylinder 7 releases, and the workpiece is placed in the target position, completing one loading cycle.
