Abstract
Description
An automatic centering device for laser cutting of automotive gaskets Technical Field
[0001] This utility model relates to the field of laser cutting technology for automotive gaskets, specifically to an automatic centering device for laser cutting automotive gaskets. Background Technology
[0002] Adjusting the position of the laser nozzle is a crucial step in ensuring precise laser beam alignment. Smoothly apply transparent or white adhesive tape to the nozzle end face, ensuring the tape is oriented in a fixed direction and not rotated 45 degrees. Set the laser spot firing power to 10%-20% (depending on equipment requirements). Briefly press the spot firing button to leave a laser hole on the tape. After removing the tape, locate a circle with the same diameter as the nozzle hole and check if the laser hole is centered at 45 degrees. If the hole is off-center, the laser is not aligned with the nozzle center. Use an Allen wrench to adjust the left and right adjustment screws on the cutting head to make the adjustment. This method requires repeated adjustments by the operator, gradually moving the laser spot to the center of the circle. Due to the poor precision of manual adjustment, multiple tests are needed until alignment is achieved, resulting in low adjustment efficiency. Summary of the Invention

[0020] Referring to Figures 1 and 2, a guide rod 15 is connected to the top of the sliding plate 8. The top of the guide rod 15 is slidably connected to the horizontal plate 6. The sliding plate 8 is slidably connected to the side plate 3. A groove is provided on one side of the horizontal plate 6 corresponding to the industrial camera 14. When the cylinder 7 is pushed to retract and move the sliding plate 8 upward, the guide rod 15 can ensure stable movement. While the sliding plate 8 rises, the groove allows the industrial camera 14 to pass through.
[0021] Referring to Figure 2, the left and right clamps are connected by the same bolt on the side closest to each other, and the bottom of the left and right clamps are on the same horizontal line as the nozzle. When not in use, the switching plate 10 is raised, and the side plates 3 on both sides will not affect the operation of the nozzle.
[0022] Referring to FIG3, the inspected mechanism 11 includes a connecting seat 111 connected to the top of the switching disk 10 and a supplementary light 112 located inside the connecting seat 111. A fixing cover 114 is connected to the top of the connecting seat 111, and a test object 113 is connected between the fixing cover 114 and the connecting seat 111. The test object 113 can be made of transparent tape or black photographic paper.

[0024] The implementation principle of this application is as follows: When this utility model is in use, the cylinder 7 is pushed to extend and push the sliding plate 8 to move down, thereby driving the switching disk 10 to move down. Then, the drive motor 9 drives the switching disk 10 to rotate, causing one group of inspected mechanisms 11 to rotate directly below the nozzle. Then, laser spotting is started. After spotting is completed, the drive motor 9 drives the inspected mechanism 11 to rotate and switch to below the industrial camera 14. At the same time, the other group of inspected mechanisms 11 rotates to directly below the nozzle. The laser hole is photographed by the industrial camera 14 for observation. The photographed image is displayed on the display 5. Then, by passing through the laser hole and the center, a signal is sent to drive the corresponding adjustment unit 2 to adjust the adjustment bolt. The adjustment angle is controlled by the servo motor. After the adjustment is completed, spotting is started again on the other group of inspected mechanisms 11, and they are rotated to be tested under the industrial camera 14. The adjustment results are observed. After debugging, the photographic paper 113 in the two groups of inspected mechanisms 11 is replaced for later use.
