Embodiment 1
[0028] Such as Figure 1-2 As shown, the laser coding equipment used for coding the automobile body in this embodiment includes: a motion mechanism 6, which stores the coding track information of the coding content corresponding to different vehicle models (the coding content includes VIN code , can specifically be characters or patterns such as numbers and letters, and the coding trajectory information is the moving path of the laser, and the coding content is formed through the moving path), in this embodiment, the moving mechanism 6 is a multi-axis moving mechanism, This satisfies the coding of multiple models and different moving positions, and the repeat positioning accuracy of the motion mechanism 6 is ±0.2mm;
[0029] Laser coding device 4, which is connected to the moving mechanism 6, and generates laser for coding, and can move with the moving mechanism 6. At the same time, the coding range of the laser coding device 4 is ≥ 120×60mm 2 , depth of focus ≥ 3mm, coding d...
Embodiment 2
[0034] This embodiment still provides a kind of laser coding equipment used for marking the automobile body. device), which is connected to the motion mechanism 6, and is used to obtain the height information of the vehicle body, and compare it with the standard vehicle body height information, because the height position of the coding area 2 on the vehicle body 1 is fixed, therefore, by The position information of the actual coding area 2 can be obtained by comparing with the standard vehicle height information; further, the measuring device 3 sends the comparison result to the motion mechanism 6; the motion mechanism 6 receives the comparison result, and based on this Drive the laser coding device 4 to accurately move to the coding area 2 of the automobile body 1; in this embodiment, the measuring range of the measuring device 3 is 300-500mm, the measurement deviation range is ±5mm, and the measurement accuracy is 0.1mm. Since the deviation of the general body size in the he...
Embodiment 3
[0038] This embodiment provides a laser marking method for an automobile body realized by the laser marking device described in Embodiment 1 or 2, such as Figure 4 As shown, it includes the following steps:
[0039] S1. Set the number of times of coding on the main control device. After the car body enters the coding station, the main control device obtains the information of the car model, calls the coding content corresponding to the car model, and sends the code The code content is sent to the motion mechanism;
[0040] S2. The measuring device obtains the height information of the vehicle body, and compares it with the standard body height information to obtain a comparison result, and sends the comparison result to the motion mechanism; the motion mechanism receives the comparison result, And accordingly drive the laser coding device to accurately move to the coding area of the automobile body 1;
[0041] The main control device controls the laser coding device to ge...
