Description

Technical Field

[0001] This utility model belongs to the field of guiding device technology, and more specifically, it relates to a guiding device for processing irregularly shaped materials based on visual recognition. Background Technology

[0002] Against the backdrop of the rapid development of modern manufacturing, irregularly shaped materials, namely those with irregular shapes, special contours, or complex geometric structures, are being processed and applied more and more widely. Typical applications include the processing and manufacturing of complex curved metal components in the aerospace field, which have extremely high requirements for the strength and precision of the materials; and the production of various irregular plastic parts in automobile manufacturing, whose quality directly affects the overall performance and appearance of the car. However, due to the special shape of irregularly shaped materials, traditional processing methods are difficult to meet the high-precision and high-quality processing requirements, resulting in low processing efficiency and high scrap rates, which seriously restricts the development of related industries.

[0003] Currently, robotic arms typically require guiding devices to assist in processing irregularly shaped materials, but existing processing guiding devices have significant technical shortcomings:

[0004] Firstly, existing guide structures generally lack the function of real-time detection of the travel accuracy of the processing device. During equipment maintenance, it is necessary to rely on special testing equipment to complete the detection of travel accuracy, which increases maintenance costs and operational complexity.

[0005] Secondly, the existing guiding structure has a single function. When the robotic arm processes irregularly shaped materials along a straight line, it is difficult to effectively suppress the vibration generated by the robotic arm during the movement. This vibration will directly lead to a decrease in processing accuracy, which cannot meet the increasingly stringent processing accuracy requirements of irregularly shaped materials, and has become a key bottleneck restricting the development of irregularly shaped material processing technology. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model relates to a vision-based guiding device for processing irregularly shaped materials. This addresses the common lack of real-time detection capabilities for the movement accuracy of existing guiding structures. During equipment maintenance, specialized testing equipment is required to assess movement accuracy, increasing maintenance costs and operational complexity. Furthermore, existing guiding structures are functionally limited; when the robotic arm processes irregularly shaped materials along a straight line, it struggles to effectively suppress vibrations generated during movement. These vibrations directly lead to decreased processing accuracy, failing to meet the increasingly stringent precision requirements for processing irregularly shaped materials and becoming a key bottleneck restricting the development of irregularly shaped material processing technology.

[0007] The first aspect of this disclosure provides a visual recognition-based guiding device for processing irregularly shaped materials, achieved through the following specific technical means:

[0008] A vision-based guiding device for processing irregularly shaped materials, comprising:

[0009] The mounting mechanism includes a main body and assembly holes. The main body has a U-shaped structure. The assembly holes are symmetrically located at both ends of the inner side of the main body. The mounting mechanism is equipped with a sliding mechanism. The sliding frame of the sliding mechanism is located on the front side of the main body, and the rear side of the sliding frame can slide horizontally along the guide rod on the inner side of the main body. The mating block on the rear side of the sliding frame slides in cooperation with the guide groove on the guide rod. The mounting mechanism is equipped with two sets of guide mechanisms. The guide plates of the guide mechanisms are located on both sides of the upper end of the main body, and the fixing rod at the outer end of the guide plate slides in cooperation with the mounting hole on the upper part of the main body. The positioning hole in the fixing rod is penetrated by the locking rod on the main body.

[0010] According to some solutions of this utility model, the installation mechanism includes: a guide rod, a guide groove, and a mounting rod; the guide rod is located on the inner front side of the main body; the guide groove is opened at the upper end of the guide rod; the mounting rod is located at the outer end of the guide rod, and the mounting rod is inserted into the assembly hole.

[0011] According to some solutions of this utility model, the installation mechanism includes: mounting holes and locking rods; the mounting holes are symmetrically opened on both sides of the upper end of the main body; the locking rods are vertically inserted into both sides of the upper end of the main body, and the locking rods pass through the mounting holes.

[0012] According to some embodiments of this utility model, the sliding mechanism includes: a sliding frame, a mating block, and a tightening bolt; the sliding frame has a rectangular structure; the mating block is disposed inside the rear side of the sliding frame; and the tightening bolt is threadedly installed on the rear side of the sliding frame.

[0013] According to some solutions of this utility model, the sliding mechanism includes: a sliding groove and a moving platform; the sliding groove is formed inside the sliding frame; the moving platform is movably installed in the sliding groove by a screw.

[0014] According to some solutions of this utility model, the guiding mechanism includes: a guide plate, a fixing rod, and positioning holes; the upper end of the guide plate has a wedge-shaped structure; the fixing rod is symmetrically arranged on the back of the guide plate, and the outer end of the fixing rod is provided with a scale groove; the positioning holes are equidistantly arranged on the inner side of the guide plate, and the through positioning holes are arranged vertically.

[0015] According to some solutions of this utility model, the guiding mechanism includes: side holes and an outer plate; the side holes are symmetrically arranged on both sides of the guide plate; the outer plate is located at both ends of the guide plate, and the circular rod on the outer side of the outer plate is inserted into the side hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this device, a fixed rod is installed on the side of the guide plate and slides into the mounting hole. A scale is set on the fixed rod to set the distance between the two sets of guide plates. By inputting a command, the moving stage drives the robotic arm through the two sets of guide plates. When a deviation occurs, the robotic arm will contact the guide plate, thereby causing the fixed rod to move within the mounting hole. By observing whether the locking rod can be smoothly inserted into the positioning hole of the fixed rod, it is possible to quickly determine whether there is a deviation in the movement of the robotic arm. This achieves the detection of the travel accuracy of the processing device without relying on special testing equipment, reducing maintenance costs and simplifying the operation process.

[0018] 2. In this device, when processing irregularly shaped materials in a straight line, the external plates inserted at both ends of the guide plate together with the guide plate provide guidance and constraint for the robotic arm. The robotic arm moves in close contact with the guide plate and external plates during processing, which can effectively resist the vibration generated during movement, greatly reduce the shaking of the robotic arm, significantly improve the processing accuracy, and meet the increasingly stringent high-precision processing requirements of irregularly shaped materials.

The fixing rod 3011 of the guide plate 301 is inserted into the mounting holes 103 on both sides of the upper end of the main body 101. Referring to the scale groove on the outer end of the fixing rod 3011, the two sets of guide plates 301 are moved to both ends of the workpiece processing position so that the spacing of the guide plates 301 is adapted to the passing size of the robotic arm.
