[0002] Assembly stations are the core operational areas in manufacturing where workers assemble and debug parts. Their efficiency and quality directly affect the product qualification rate. By combining high-precision CCD camera attitude capture and dynamic error correction algorithms, a closed loop of "collection-analysis-feedback" is constructed, providing a technical foundation for the gradual realization of intelligent manufacturing evolution from "human assistance → human-machine collaboration → fully automated assembly".
[0003] Existing human-machine collaboration technologies still have some problems during use. For example, the robotic arm is permanently fixed by welding or bolts, and replacement / maintenance requires professional tools and a long downtime, which affects assembly efficiency. Workers' non-standard operation and manual inspection or video playback cannot correct errors in real time, resulting in batch defects. To address these issues, we provide a dynamic error correction device for human-machine collaboration posture at the assembly station. Utility Model Content
[0004] The purpose of this invention is to provide a dynamic error correction device for human-machine collaboration posture at an assembly station. By cooperating with the posture acquisition and correction mechanism and the fixing mechanism, it solves the problem in the existing human-machine collaboration technology that requires professional tools for replacing / maintaining the robotic arm and has a long downtime, which affects assembly efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0006] This utility model relates to a human-machine collaborative posture dynamic error correction device for an assembly station, comprising an assembly table, a support frame fixedly connected to the top of the assembly table, an posture acquisition and error correction mechanism fixedly connected to one side of the support frame, a vertical plate fixedly connected to the top of the assembly table, robotic arms mounted on both sides of the vertical plate, and fixing mechanisms mounted on both sides of the vertical plate. The posture acquisition and error correction mechanism includes a CCD camera fixedly connected to one side of the support frame, a display screen fixedly connected to one side of the support frame, and a control terminal fixedly connected to one side of the support frame. The fixing mechanism includes a fixing box fixedly connected to both sides of the vertical plate, a fixing block fixedly connected to one side of the robotic arm, a fixing plate inserted into the fixing block, and an anti-detachment rod inserted into the fixing plate.
[0007] The present invention is further configured such that a buzzer is installed inside the display screen, the front side of the assembly table is a worker assembly area, and the posture acquisition and error correction mechanism is located on one side of the worker assembly area.
[0008] The present invention is further configured such that a fixing groove adapted to the fixing block is provided on one side of the fixing box, and anti-detachment plates are fixedly connected to the top and bottom of the fixing block, and an anti-detachment groove adapted to the anti-detachment plate is provided inside the fixing box.
[0009] The present invention is further provided that the fixing box and the fixing block are both provided with fixing holes adapted to the fixing plate, and the surface of the fixing plate is provided with an anti-detachment through groove adapted to the anti-detachment rod.
[0010] The present invention is further configured such that the bottom of the fixing box is provided with an insertion through hole adapted to the anti-detachment rod, and the anti-detachment rod is located at the bottom of the fixing box.
[0011] The present invention is further configured such that electric push rods are fixedly connected to both sides of the vertical plate, and the top of the electric push rods is fixedly connected to the bottom of the anti-detachment rod.

[0013] The present invention has the following beneficial effects.
[0014] 1. This utility model uses a CCD camera to capture the worker's operating posture in real time, and the control terminal embeds an AI algorithm to accurately compare with the standard action template. Once an assembly error is detected, the display screen is immediately triggered to highlight the error part and overlay the correct action animation. At the same time, the buzzer sounds an alarm to prompt the operator to stop the erroneous operation. This closed-loop system transforms post-production quality inspection into process interception, reduces the assembly defect rate, and accumulates a data foundation for fully autonomous assembly by the robotic arm.
[0015] 2. This utility model innovates a three-level locking mechanism: the fixing block is embedded in the fixing groove of the fixing box to achieve lateral limiting → the anti-detachment plate is stuck into the anti-detachment groove to resist shearing force → the electric push rod drives the anti-detachment rod through the fixing plate to complete vertical locking. When disassembling, the robotic arm can be pulled out simply by retracting the anti-detachment rod. No tools are required for operation, reducing maintenance time and helping to reduce production line downtime losses.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figures 1-5 This utility model is a human-machine collaborative posture dynamic error correction device for an assembly station, including an assembly table 1, a support frame 2 fixedly connected to the top of the assembly table 1, a posture acquisition and error correction mechanism 3 fixedly connected to one side of the support frame 2, a vertical plate 4 fixedly connected to the top of the assembly table 1, robotic arms 5 on both sides of the vertical plate 4, and fixing mechanisms 6 on both sides of the vertical plate 4. The posture acquisition and error correction mechanism 3 includes a CCD camera 301 fixedly connected to one side of the support frame 2, a display screen 302 fixedly connected to one side of the support frame 2, and a control terminal 303 fixedly connected to one side of the support frame 2. The fixing mechanism 6 includes a fixing box 601 fixedly connected to both sides of the vertical plate 4, a fixing block 602 fixedly connected to one side of the robotic arm 5, a fixing plate 603 inserted into the fixing block 602, and an anti-detachment rod 604 inserted into the fixing plate 603.
[0027] Specifically: Through the setting of posture acquisition and correction mechanism 3, the CCD camera 301 collects the assembly process of the operator at the assembly station. The AI algorithm embedded in the control terminal 303 compares the captured data with the standard action template, highlights the incorrect parts on the display screen 302, overlays the correct action diagram, triggers the buzzer to emit an alarm sound, prompting the operator to interrupt the incorrect operation, and provides the robotic arm 5 with operator action status information to realize dynamic task allocation. The posture acquisition and correction mechanism 3 ensures the standardization of manual actions and accumulates data for the later fully autonomous assembly of the robotic arm 5. Through the setting of fixing mechanism 6, the rapid assembly and disassembly between the robotic arm 5 and the vertical plate 4 is realized. Specifically, the fixing block 602 is embedded in the fixing box 601 and cooperates with the anti-detachment plate 7 and the anti-detachment groove 8 to achieve initial positioning and anti-shear; the fixing plate 603 is inserted into the fixing hole 9 to provide lateral constraint; the electric push rod 12 drives the anti-detachment rod 604 to insert into the anti-detachment through groove 10 and the insertion through hole 11 to achieve vertical locking. This structural design facilitates the installation and disassembly of the robotic arm 5 by controlling the electric push rod 12 to raise and lower the anti-detachment rod 604, thus simplifying the operation process.
[0028] Example 2
[0029] Please see Figures 1-5 Based on Embodiment 1, a buzzer is installed inside the display screen 302, the front side of the assembly table 1 is the worker assembly area, the posture acquisition and correction mechanism 3 is located on one side of the worker assembly area, a fixing groove adapted to the fixing block 602 is opened on one side of the fixing box 601, and anti-detachment plates 7 are fixedly connected to the top and bottom of the fixing block 602, and anti-detachment grooves 8 adapted to the anti-detachment plates 7 are opened inside the fixing box 601, and anti-detachment grooves 8 adapted to the anti-detachment plates 7 are opened inside both the fixing box 601 and the fixing block 602, and anti-detachment grooves 8 adapted to the fixing plates 603 are opened inside both the fixing box 601 and the fixing block 602. The fixed plate 603 has a matching fixed insertion hole 9, and the surface of the fixed plate 603 has an anti-detachment through groove 10 that matches the anti-detachment rod 604. The bottom of the fixed box 601 has an insertion through hole 11 that matches the anti-detachment rod 604. The anti-detachment rod 604 is located at the bottom of the fixed box 601. Electric push rods 12 are fixedly connected to both sides of the vertical plate 4. The top of the electric push rod 12 is fixedly connected to the bottom of the anti-detachment rod 604. An installation plate is fixedly connected to the bottom of the vertical plate 4. The installation plate is fixedly connected to the top of the assembly table 1 by bolts.
[0030] Specifically: a buzzer is used to issue an alarm to alert assembly workers of assembly process errors; the posture acquisition and correction mechanism 3 and the worker assembly area are used to collect the worker's posture during assembly; a fixing groove is used to fix the fixing block 602 inside the fixing box 601; the anti-detachment plate 7 and the anti-detachment groove 8 are used to limit the fixing block 602 and prevent it from sliding outward; the fixing hole 9 allows the fixing plate 603 to be inserted into the fixing box 601 and the fixing block 602; the anti-detachment through groove 10 allows the anti-detachment rod 604 to be inserted into the fixing plate 603 and limit its movement to prevent it from slipping; the insertion through hole 11 allows the bottom anti-detachment rod 604 to be inserted upward into the fixing box 601; the electric push rod 12 is used to move the anti-detachment rod 604 up and down; and the mounting plate is used to fix the vertical plate 4 at a designated position on the assembly table 1.
[0031] The working principle of this utility model is as follows: When installing the robotic arm 5, the fixing block 602 on the robotic arm 5 is inserted into the fixing groove of the fixing box 601. The fixing block 602 is pushed to one side by the robotic arm 5 so that the fixing block 602 contacts the inner wall of the fixing box 601. Then, the fixing plate 603 is inserted into the corresponding fixing hole 9. Then, the electric push rod 12 drives the anti-detachment rod 604 to move upward and enter the fixing box 601 through the insertion through hole 11 at the bottom of the fixing box 601. Then, it continues to be inserted upward into the anti-detachment through groove 10 of the fixing plate 603. At this time, the fixing block 602 is limited and the robotic arm 5 is installed.
[0032] During assembly, workers assemble workpieces in the worker assembly area. During the assembly process, CCD camera 301 collects the worker's assembly process, and control terminal 303 records and analyzes the collected information. When an error occurs in the worker's assembly process, the screen marks the error location and overlays a standard posture animation, the buzzer sounds three short alarms, and the current collaborative task of robotic arm 5 is paused until the posture is corrected, thus realizing a closed loop of "perception-decision-execution".
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
