How to achieve large-format laser cutting? XY two-axis platform plus vision!

The laser marking machine in the prior art is mainly used for marking objects on the assembly line. During the marking process, the position of the workpiece on the assembly line is often required to be consistent with the position of the template workpiece. In actual production, expensive tooling fixtures are required to position the workpiece, which has a high manufacturing cost and is not intelligent enough.

In addition, the marking machine with visual inspection function in the prior art has the problems of cumbersome and complicated operation, long image processing time and the need to mark the workpiece in a stationary state. Therefore, it is required that the conveyor belt be controlled to stop moving after the workpiece reaches the designated marking position, and then be restarted after the workpiece marking is completed. This operation mode makes it impossible for the conveyor belt to transmit too fast when the automatic alignment marking system is in use, otherwise it will greatly affect the production efficiency of workpiece marking and thus affect the production benefits of the enterprise.

This requires an online vision-guided laser marking system that can reduce production costs, is easy to operate, improves production efficiency, and has strong versatility. It can effectively solve the technical problems of the existing marking machines that are cumbersome to operate and have low work efficiency.

XY axis platform visual positioning and marking system

XY axis moving platform CCD visual positioning laser marking system can realize accurate marking as long as the product is within the processing range of the laser marking scanning galvanometer, that is, even if the position is different each time, the processing position can be fine. The CCD visual positioning marking system uses the principle of visual positioning. First, the template of the product is formulated, and the standard template is saved. During processing, the product is photographed, and the computer is used for comparison and position positioning. After adjustment, the product can be accurately processed. The shape of the processed product can be round, square, and irregular shapes. This process is particularly suitable for small products. It can avoid the processing of positioning trays and fixing fixtures, greatly saving the laser marking processing cycle.

System Features:

1. One-key automatic calibration, linking the laser and visual coordinates;

2. One-key distortion correction, suitable for high-precision occasions, to calibrate the visual lens;

3. Adaptive automatic positioning mode, only need a frame to realize automatic positioning function, single multiple product marking;

4. Marking information can be fixed or changed (support communication access);

5. Communication support: IO, TCP/IP, RS232, RS485 and other protocols;

6. Multi-template product management, convenient switching of different products;

7. The camera has a large imaging field of view, suitable for marking any flat product;

8. The camera can automatically identify and mark products at any angle and in any quantity;

9. It can be integrated with laser optical paths of various wavelengths such as optical fiber, CO2, and semiconductors;

10. Splicing and marking of large-format products can be achieved through motion control;

11. It takes up little space and does not occupy any space on the work platform, so the existing laser installation space can be upgraded.

Product advantages:

1. Reduce production costs

It can adjust the working posture in real time according to the workpiece to be marked and mark accurately. There is no need to assemble expensive high-precision fixtures to limit the shape and position of the marked workpiece, which greatly reduces the production cost.

2. Simple operation and convenient use

Compared with existing visual marking machines, the XY axis platform visual positioning marking system only needs to be triggered once and only needs to take a frame of image and send it to the image processing system for comparison with the template workpiece image to complete the corresponding data comparison and adjustment work. In addition, different types of products only need to create one template, which is simple to operate and easy to use.

3. Improve production efficiency

In the existing technology, most visual marking machines use a coaxial optical path structure between the camera and the marking machine. The marking machine can only mark the workpiece when it runs into the working range of the marking machine and is in a stationary state, so the working efficiency is low. However, our XY-axis platform visual positioning marking system can mark multiple workpieces at the same time within the camera's field of view, so it can effectively improve production efficiency compared to the existing visual marking machine.

4. Strong versatility

The existing visual marking machines need to be used with corresponding marking software and control boards, while our XY-axis platform visual positioning marking system only needs to adopt the universal marking machine protocol, so it does not need to rely on specific control boards and marking software, and has the advantages of strong versatility.

Application areas:

IC marking, keyboard marking, consumer electronics product marking, wafer marking, automotive parts marking, battery welding marking, thin-film solar cell marking, etc.
