Description

1. Technical field

[0002] The utility model belongs to the technical field of wheel hub manufacturing, and particularly relates to a two-dimensional code engraving device for an automobile wheel hub. 2. Background technology

[0004] QR codes have the advantages of large capacity, strong confidentiality, strong resistance to damage and error correction, and are widely used in product identification and logistics management. In the current stage of wheel production, the original product traceability records are recorded and saved by manual identification or semi-automatic methods. When tracing back, it is necessary to look through previous records, which requires a lot of manpower and financial resources to achieve. Therefore, when the wheel is produced, engraving a QR code on the wheel can perfectly solve this problem. In the existing production line, when engraving a QR code on the wheel, it is often an industrial robot that engraves a wheel at a workstation. Due to the high cost of the laser and industrial camera carried by the industrial robot, its utilization rate is reduced, which greatly increases the production cost of the wheel. (III) Summary of the invention

An industrial robot carrying a laser and an industrial camera can engrave the wheels on both sides of the workstations, thereby improving the utilization rate of the equipment and saving the production cost. (IV) Description of the drawings

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] Attached Figure 1 It is a structural schematic diagram of the utility model;

[0017] In the figure, 1 is an industrial robot, 2 is a conveyor roller, 3 is a one-dimensional code detector, 4 is a wheel hub gripper, 5 is an industrial camera, 6 is a rangefinder, 7 is a laser, 8 is a grating detector, 9 is a centering push rod, 10 is a centering cylinder, 11 is a flip axis, 12 is a flip motor, and 13 is a lifting cylinder. (V) Specific implementation methods

[0019] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes an industrial robot 1, with conveying rollers 2 provided on both sides of the industrial robot 1, a one-dimensional code detector 3 provided above the conveying roller 2, a hub clamp 4 provided at the front of the conveying roller 2, an industrial camera 5, a rangefinder 6 located above the industrial camera 5, and a laser 7 located above the rangefinder 6 provided on the upper part of the industrial robot 1. A grating detector 8 is provided above the hub clamp 4. Centering push rods 9 are provided on both sides of the conveying roller 2, and the centering push rods 9 are installed at the output end of the centering cylinder 10. The hub clamp 4 is installed on the flip shaft 11, and the flip shaft 11 is driven by the flip motor 12. The flip motor 12 is installed on the lifting cylinder 13.

[0020] With the automobile wheel hub two-dimensional code engraving device of the utility model, the wheel hub enters the conveyor roller 2 of the one-dimensional code scanning station from the running roller through the code engraving waiting process, and the one-dimensional code linear laser scanning device in the one-dimensional code detector 3 scans the 3D one-dimensional code on the side of the wheel hub. By comparing the one-dimensional code database, the wheel hub model and information are retrieved and transmitted to the central control server. The server integrates the wheel hub offline time, product production line information, temperature information, heat treatment information and other contents, generates a two-dimensional code, and sends it to the laser 7 for standby. After the wheel hub is scanned by the one-dimensional code, it arrives at the wheel hub flipping station, and the grating detector 8 detects whether the wheel hub is in the center position of the conveyor roller 2. If not, the centering cylinder 10 drives the centering push rod 9 to push the wheel hub to be centered. After the centering is completed, according to the wheel hub model, wheel hub diameter and height information retrieved from the database, the lifting cylinder 13 drives the flipping motor 12 to descend to the appropriate position for clamping the wheel hub, the wheel hub clamp 4 clamps the wheel hub, and the lifting cylinder 13 drives the flipping motor 12 to rise. After rising to the appropriate height, the flipping motor 12 is started. During the wheel hub flipping process, the industrial robot 1 carries the laser 7 and the industrial camera 5 to the top of the wheel hub. The flipping is completed, the industrial camera 5 takes a picture of the inner flange of the wheel hub, and the visual software calculates the coordinates of the center of the inner flange of the wheel hub and the position to be coded, and transmits the coordinates to the industrial robot 1. The industrial robot 1 moves to the top of the coding position according to the coordinate axis, and the rangefinder 6 measures the coding position. The measurement data is transmitted to the industrial robot 1. The industrial robot 1 adjusts the Z-axis height according to the measurement data and the focal length of the laser 7, so that the distance between the lens of the laser 7 and the wheel hub coding position is within the focal length error range of the laser 7, and the laser 7 starts to etch the QR code.

[0021] After the QR code is etched, the industrial robot 1 swings to a different position and swings the industrial camera 5 again to the top of the wheel hub to take a picture of the wheel hub QR code to identify whether the QR code etching is successful. After completion, the industrial robot 1 carries the laser 7 to the other side to continue the coding process. The laser 7 and the industrial camera 5 are the most expensive equipment in this system, accounting for about 75% of the total value of the entire set of coding equipment. The industrial robot 1 carries the laser 7, the rangefinder 6, and the industrial camera 5 to realize a set of equipment for two-station coding, which greatly increases the equipment utilization rate and significantly reduces the equipment cost.
