[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an online laser marking device for circuit boards, comprising:

[0028] Conveyor line 1, which is used to transmit circuit board 1;

[0029] The laser marking assembly 2 includes a first mounting frame 21, an adjustment component 22, and a laser marking device 23. The first mounting frame 21 is disposed on the conveyor line 1, the adjustment component is disposed on the first mounting frame 21, and the laser marking device 23 is disposed on the adjustment component 22. The laser marking device 23 is located above the conveyor line 1.

[0030] A guiding component 3 is disposed on the conveyor line 1 and located at one end of the first mounting bracket 21. The guiding component 3 includes a second mounting bracket 31, a linear module 32, a moving guiding plate 33, and a fixed guiding plate 34. A second mounting bracket 31 is respectively disposed at both ends of the linear module 32 and is connected to the conveyor line 1. The moving guiding plate 33 and the fixed guiding plate 34 are respectively connected to both ends of the linear module 32. The linear module 32 drives the moving guiding plate 33 to move, and the fixed guiding plate 34 is fixedly connected to the linear module 32. A photoelectric probe 4 is disposed on the linear module 32.

[0031] The position signal of the circuit board detected by the photoelectric probe is sent to the control cabinet (not shown). The control cabinet controls the movement of the linear module, causing the moving guide plate to move towards the fixed guide plate. This aligns both sides of the circuit board 6 with the moving and fixed guide plates respectively, allowing the laser marking device to mark at the same position on the circuit board. Similarly, a photoelectric probe is also installed on the laser marking assembly. The control cabinet controls the laser marking device based on the position signal of the circuit board 6 detected by the photoelectric probe on the laser marking assembly.

[0032] Both the moving guide plate 33 and the fixed guide plate 34 are provided with pads 5. The pads are elastic pads, which can protect the circuit board.

[0033] The adjusting component 22 includes a first cylinder 221 mounted on the first mounting bracket 21. The piston rod of the first cylinder 221 is connected to a slide block 222. The slide block 222 is slidably connected to a first slide rail 223 on the first mounting bracket 21. A mounting plate 224 is mounted on the slide block 222. A second cylinder 225 is mounted on the top of the mounting plate 224. A slider 226 is connected to the bottom of the second cylinder 225. The slider 226 is slidably connected to a second slide rail 227 on the side of the mounting plate 224. The laser marking device 23 is mounted on the slider 226. The first cylinder can drive the slide block to move back and forth on the first slide rail, thereby adjusting the position of the mounting plate. The second cylinder drives the slider to move up and down on the second slide rail, thereby adjusting the position of the laser marking device and improving the marking quality.

[0034] A connecting plate 228 is provided on the slider 226, and the laser marking device 23 is mounted on the connecting plate 228. This facilitates the installation of the laser marking device.

[0035] The conveyor line 1 is a roller conveyor line.

[0036] Working principle: By installing laser marking components and alignment components on the conveyor line, when the circuit board passes the alignment component during the conveying process, the linear module will drive the moving alignment plate to move towards the fixed alignment plate, so that the two sides of the circuit board are aligned with the moving alignment plate and the fixed alignment plate respectively, making the circuit board parallel to the conveyor line and correcting any skewed circuit boards. After that, the aligned circuit board continues to move forward on the conveyor line. When it passes the laser marking device, the laser marking device can mark the circuit board. Marking can be achieved on the circuit board during the conveying process, which improves the marking efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
