[0091] Example 8

[0092] A high-speed, 3D vision-guided automated assembly solution for production lines without precise positioning is proposed. The system includes a production line, a support mold, a vision system, a robotic arm, a fastening module, a screw feeding mechanism, a PLC control system, an electrical cabinet, a safety system, and a frame.

[0093] Production process:

[0094] 1) The operator places the bumper product on the assembly line, assembles other parts, and then moves it to the screw assembly station. The bumper is simply placed on the mold, with only simple support and no precise positioning. The position of the bumper is different each time, so a 3D vision camera is needed to take pictures to guide the screw assembly.

[0095] 2) After the bumper moves to the screw assembly station, it pauses for 40 seconds. At this time, the control system sends a vision command to the vision system camera to move along the convex guide rail via a servo motor. It first moves to the vicinity of the shooting area 1 to take a picture. After taking the picture, it identifies the two screw holes. After image processing, the signal is transmitted to the robotic arm and the screw feeding system. The screw feeding system first delivers the screw to the air blower alligator mouth of the locking module. At the same time, the robotic arm grabs the locking module and moves it to the shooting area 1. It moves forward and adjusts the two locking bits to the corresponding width via the first servo motor. Then, it moves forward via the second and third servo motors to lock the screw onto the bumper.

[0096] 3) The width adjustment of the locking bit is controlled by the first servo motor, which moves along the servo bidirectional lead screw. The position control is a fixed width programmed into the program.

[0097] 4) When tightening the screw, the second and third servo motors, through the screw tightening screw, rotate the screw forward and lock it into the corresponding hole on the bumper.

[0098] 5) The other six screws shall be assembled in three stages following the above procedure.

[0099] 6) After the screws are assembled, the mold is moved to the next station, and then the above operation is repeated.

[0100] This solution enables the automated assembly of parts such as screws, push pins, and radar, solving problems such as low efficiency, poor error prevention, and high costs associated with manual assembly due to increased manpower and molds during high-speed assembly.

[0101] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various changes can be made to the above embodiments of this utility model. For example, the number of robotic arms can be increased, the screw feeding method can be changed, and the assembly parts can be changed to push screws, nut clamps, radar, etc., to improve production capacity and compatibility with more products.

[0102] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
