Description

Technical Field

[0001] This utility model relates to the field of visual inspection of robot end effectors, specifically to a universal target mounting linkage device for robot end flanges. Background Technology

[0002] In robot performance testing, the target serves as a key measurement element. The stability and proper positioning of the target directly impact the testing quality and are crucial for the accuracy of data acquisition. Precise measurement of the target's position allows for the acquisition of the robot's end effector's pose information, thereby enabling the evaluation of core performance indicators such as motion accuracy and repeatability of industrial robots. For instance, on industrial production lines, high-precision robots need to ensure that the end effector's positioning error is within a minimal range during repetitive tasks, which relies on the accurate measurement and analysis of target position data.

[0003] Existing target installation methods have the following limitations: 1) Due to unreasonable target installation positions or the influence of vibration and impact during robot movement, data acquisition is prone to data loss. When the robot performs high-speed or complex trajectory movements, the target may temporarily leave the field of view of the measuring equipment, causing data acquisition interruption and affecting the complete analysis of robot performance accuracy. 2) Fixed-installation targets may not be able to reach certain specific measurement space positions of the robot. For example, when the robot is working in a specific scenario, the range of motion of its end effector is limited by its own structure and the surrounding working environment. If the target installation position is improper, it may not be able to cover all the workspace areas that need to be detected by the robot, thus making it impossible to comprehensively evaluate the robot's performance in the entire workspace. 3) Detection equipment (such as infrared detection systems) has certain requirements for the installation position of the target to ensure measurement accuracy. However, traditional fixed-connection target installation methods cannot meet the optimal installation position requirements of the measuring equipment.

[0004] Currently, robot end flanges commonly come in various sizes such as M3, M4, M5, and M6, which need to be adapted to different types of targets, making target installation very inconvenient. Utility Model Content

[0005] To at least partially address the shortcomings of the existing technology, the main objective of this utility model is to provide a universal target mounting linkage device for robot end flanges, which has the advantages of simple and convenient connection and strong practicality.

[0006] To achieve the aforementioned main objectives, this utility model discloses a universal target mounting link device for robot end flanges, comprising a target, a support link, a mounting link, and a locking assembly. The support link has a connecting end and a mounting end. The connecting end is plate-shaped and has a connecting groove extending along the length of the support link. The locking assembly includes a first locking member and a second locking member. The first locking member passes through the connecting groove and connects to the robot end flange, pressing the connecting end against the surface of the robot end flange. The mounting link is attached to the mounting end via the second locking member. The target is removably mounted on the mounting link. The first locking member is configured to slide and lock within the connecting groove to change the relative position of the target and the robot end flange.

[0007] According to a specific embodiment of the present invention, the locking assembly further includes a washer, and the first locking member passes through the washer and the connecting groove in sequence to connect with the robot end flange.

[0008] Furthermore, the first locking element includes locking bolts of different sizes and specifications.

[0009] According to a specific embodiment of this utility model, the mounting end is provided with a through hole, and the support connecting rod is vertically inserted into the through hole.

[0010] Furthermore, a blocking ring is provided in the middle of the mounting rod, and one end of the mounting rod passes through a through hole. When the second locking member locks the mounting rod, the blocking ring abuts against the mounting end.

[0011] According to a specific embodiment of the present invention, the other end of the mounting rod is provided with a stepped mounting part, and the target is inserted into the stepped mounting part.

[0012] According to one specific embodiment of this utility model, the support connecting rod is in the shape of a long strip plate.

[0013] According to a specific embodiment of the present invention, the connecting end has an auxiliary connecting platform protruding from the side away from the mounting end, and the auxiliary connecting platform is provided with a small connecting hole.

[0014] According to a specific embodiment of this utility model, both the support link and the mounting link are metal links.

[0015] Furthermore, the support link and mounting link are made of stainless steel.

[0016] This utility model has the following advantages: It provides a universal target mounting linkage device, which is adapted to the flange through a support linkage. The target is attached to the mounting end of the support linkage through the mounting linkage, realizing the quick and convenient installation of the same target on the flange. At the same time, because the connecting groove has a certain length, the distance between the mounting linkage (target) and the end flange can be adjusted, solving the problem of the target being blocked by other tooling at the end of the robot. The connection is simple and convenient, and it is highly practical.

[0017] In addition, the first locking element can be adapted to fit different flange sizes and interface types, making the entire device highly versatile. At the same time, the mounting rod can be installed circumferentially to achieve 360° full coverage of the target position, completely solving problems such as missed points, limited measurement space, and limited equipment installation position that may occur during the sampling stage.

[0018] To more clearly illustrate the purpose, technical solution, and advantages of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description with reference to the embodiments in order to provide a full understanding of this utility model; however, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of this utility model.

[0026] The general-purpose target mounting linkage device in this embodiment is used on the robot's end effector flange, primarily for enabling flexible target mounting and adjusting the target's suitable mounting position. For example... Figure 1-2As shown, the universal target mounting linkage device includes a target 10, a support link 20, a mounting link 30, and a locking assembly. The support link 20 is used to connect to the robot end flange, the mounting link 30 is attached to the support link 20 to fix the target 10, and the locking assembly is used to provide stable locking installation for the support link 20 and the mounting link 30.

[0027] like Figure 3-4 As shown, the support link 20 has a connecting end 20a and a mounting end 20b. The connecting end 20a is plate-shaped and has a connecting groove 21 extending along the length of the support link 20. The connecting groove 21 has a large width, for example, large enough to allow M6 or M8 bolts to pass through. The locking assembly includes a first locking member, which includes locking bolts of different sizes and specifications. The first locking member passes through the connecting groove 21 and connects to the robot end flange. Figure 6 As shown.

[0028] Furthermore, the locking assembly also includes a washer, and the first locking member passes through the washer and the connecting groove 21 in sequence to connect with the robot's end flange, such as... Figure 6 As shown in the example, the use of washers allows for the universal application of bolts of various sizes, enhancing its practicality. In... Figure 5 In the extended embodiment shown, the surface of the connecting groove 21 may also have a recessed groove 22, the width of which is basically the same as the diameter of the washer so as to place the washer, thus ensuring the relative accuracy of the washer installation position.

[0029] In this embodiment, the first locking member can slide and lock in place within the connecting groove 21, thereby changing the relative position of the target 10 and the robot end flange. This structure expands the measurement space, allowing the robot's performance to be measured throughout the entire workspace, avoiding performance evaluation blind spots caused by limited measurement space.

[0030] The locking assembly includes a second locking member, through which the mounting rod 30 is attached to the mounting end 20b. The mounting end 20b has a through hole 23, into which the support rod 20 is vertically inserted. The second locking member is, for example, a nut, with threads at the end of the support rod 20 inserted into the through hole 23. The mounting rod 30 is assembled through the engagement of the nut and the threads. In some embodiments, the mounting rod 30 may also be directly attached to the mounting end 20b, for example, through a plug-in connection, such as a tight fit.

[0031] Furthermore, a blocking ring 31 is provided in the middle of the mounting link 30, and one end of the mounting link 30 passes through the through hole 23. When the second locking member locks the mounting link 30, the blocking ring 31 abuts against the mounting end 20b.

[0032] The target 10 is removably mounted on the mounting rod 30. A stepped mounting part 32 is provided at the other end of the mounting rod 30, and the target 10 is inserted into the stepped mounting part 32. The target 10 can be any conventional target 10 (target ball), and the structure of the target 10 is not limited here.

[0033] For ease of installation, the support rod 20 in the embodiment is in the shape of a long plate, and the mounting rod 30 is in the shape of a long rod. Both are metal rods, such as stainless steel rods, which have high strength and high structural stability during use.

[0034] Optionally, an auxiliary connecting platform 24 protrudes from the side of the connecting end 20a away from the mounting end 20b. The auxiliary connecting platform 24 is provided with a connecting hole 25. On the one hand, the connecting hole 25 can be used directly as a fixed connecting hole when connecting small-sized flanges, further increasing the versatility. On the other hand, it can also be used in conjunction with the connecting groove 21 for multi-point fixing, increasing the stability of the structure.

[0035] The installation effect of the embodiment is as follows Figure 6 As shown, compared with the conventional target 10 installation method, the embodiment has at least the following advantages:

[0036] 1) High compatibility: The target is compatible with robot end flanges of different specifications, solving the matching problem caused by fixed connection methods.

[0037] 2) Adaptable to installation location: This device can flexibly adjust the position of the target 10 according to the installation location of the measuring equipment to meet the measurement accuracy requirements of the measuring equipment.

[0038] 3) Expanding the measurement space: The adjustability of this device enables the target to break through the spatial limitations of traditional fixed installation. By adjusting the length and angle of the support link 20, the target can reach more positions in the robot's workspace, thereby achieving comprehensive testing of the robot's performance throughout the entire workspace.

[0039] 4) Improve measurement accuracy: By optimizing the target installation method, the phenomenon of missing points can be reduced, the flexibility of the measurement space can be improved, and ultimately the accuracy of robot performance measurement can be improved.

[0040] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
