If the distance between the laser emitter 22 and the product to be processed is not adjusted, the laser beam cannot be correctly focused on the product to be processed. The specific structure of the driving assembly 21 will be described below.

[0046] The scanning module 30 is mounted on the rack 10. Here, the specific connection mode between the scanning module 30 and the rack 10 is not limited, and the designer can reasonably design according to the actual needs; for example, the scanning module 30 can be but not limited to at least one of the modes of screwing, clamping or plugging to be detachably connected with the rack 10; for another example, the scanning module 30 can also be but not limited to welded or riveted to be non-detachably connected with the rack 10.

[0047] The control module 40 is the control mechanism of the laser marking device 1; on the one hand, the control module 40 is electrically connected with the laser emitter 22, and controls the laser emitter 22 to perform laser processing on the product to be processed to form a mark when the product to be processed is in a preset processing position; on the other hand, the control module 40 is electrically connected with the scanning module 30, and controls the scanning module 30 to scan the mark formed by the laser on the processed product and store the corresponding data information; the specific structure of the control module 40 will be introduced in the following.

[0048] The control module 40 is mounted on the rack 10.

[0049] It should be noted that the laser marking device 1 in the present application is suitable for all products to be processed which need to be processed by laser and scanned, so the specific product form of the product to be processed is not limited here. After being processed by the laser module 20, the product to be processed can be but not limited to forming a pattern or a two-dimensional code on its surface.

[0050] Based on the laser marking device 1 in the present application, the control module 40 and the laser emitter 22 cooperate with each other, the control module 40 can control the laser emitter 22 to perform laser processing on the product to be processed to form a mark when the product to be processed is at a preset processing position, so that the marking operation of the product to be processed can be realized mechanically and automatically. Compared with the manual labeling operation of the product to be processed in the related art, the mark is not easy to fall off and be contaminated and invalid, and the work efficiency can be effectively improved, the personnel investment is reduced to reduce the cost. The control module 40 and the scanning module 30 cooperate with each other, and the control module 40 can also control the scanning module 30 to scan and store the corresponding data information of the mark formed by the product processed by the laser. Thus, the scanning operation of the mark formed by the product processed by the laser can be realized mechanically and automatically, and the data information stored by the control module 40 can be used for future tracing or research. Compared with the manual scanning operation of the labeled product in the related art, the work efficiency can be improved, the personnel investment is reduced to reduce the cost. The driving assembly 21 and the distance measuring assembly cooperate with each other, the driving assembly 21 can adjust the position of the connecting end thereof in the preset direction MM' based on the distance measured by the distance measuring assembly, so as to change the distance between the laser emitter 22 and the product to be processed, so that the focal length of the laser emitter 22 is adjustable. Thus, the laser emitter 22 can perform laser processing on the product to be processed of different sizes, so as to improve the practicability and applicability of the laser marking device 1.

[0051] In some embodiments, the operator can manually operate the driving assembly 21 to adjust the distance between the laser emitter 22 and the product to be processed to ensure that the laser beam is correctly focused.

[0052] In still some embodiments, the distance measuring assembly comprises a laser receiver (not shown in the figure) and a signal processing unit (not shown in the figure); the laser receiver is arranged in parallel with the laser emitter 22 to receive the laser signal reflected from the surface of the product to be processed; the signal processing unit can be a microcontroller, which is electrically connected with the laser receiver and the laser emitter 22 respectively, and is configured to calculate the distance between the laser emitter 22 and the product to be processed based on the laser signal received by the laser receiver; and the driving assembly 21 adjusts the distance between the laser emitter 22 and the product to be processed according to the distance measured by the signal processing unit.

[0053] In some embodiments, the scanning module 30 comprises a camera, the scanning module 30 can read the mark formed by the product processed by the laser through the camera, the scanning range of the camera covers the marking range of the laser emitter 22, and the control module 40 is electrically connected with the camera. The ranging assembly comprises a signal processing unit (not shown in the figure), the ranging assembly (specifically, the signal processing unit) is electrically connected with the camera of the scanning module 30, and the ranging unit (specifically, the signal processing unit) detects the distance between the laser emitter 22 and the product to be processed through the camera. For example, first, the laser emitter 22 emits a low-power laser beam to the product to be processed, when the laser emitter 22 is in focus, the laser beam will converge on the surface of the product to be processed to form a very small spot, when the laser emitter 22 is not in focus, the laser beam will diffuse on the surface of the product to be processed to form a larger spot. The spot image formed by the laser beam on the surface of the product to be processed captured by the camera will be transmitted to the signal processing unit. The signal processing unit judges whether the laser beam is in the best focus state by analyzing the size, shape and brightness of the spot, or judges whether the laser emitter 22 is in focus according to the size and shape of the spot. If the spot is small and concentrated, it means that the laser emitter 22 is in good focus and does not need to be adjusted; if the spot is large and dispersed, it means that the laser emitter 22 is not in focus and needs to be adjusted. At this time, the signal processing unit will send instructions to the driving assembly 21 to adjust the position of the laser emitter 22 until the laser beam reaches the best focus state. Then the laser emitter 22 switches to a larger power to perform laser processing on the surface of the product to be processed, and after the product to be processed is completed by laser marking, the camera reads the mark formed by the product processed by the laser. In this way, the laser module 20 reuses the camera of the scanning module 30 to realize the focusing of the laser emitter 22.

[0054] Specifically, as shown in Figures 1-3 The driving assembly 21 comprises a track 211, a connecting frame 212 and a driving member 213; the track 211 is installed on the rack 10; the connecting frame 212 is slidably connected with the track 211, and the connecting frame 212 is fixedly connected with the laser emitter 22 as a connecting end of the driving assembly 21; the driving member 213 is connected with the connecting frame 212, and the driving member 213 is configured to drive the connecting frame 212 to slide along a preset direction MM' relative to the track 211.

[0055] The track 211 is used as a support frame of the driving assembly 21 for slidably connecting with the connecting frame 212; here, the specific connection mode between the track 211 and the rack 10 is not limited, and the designer can reasonably design according to the actual needs; for example, the track 211 can be but is not limited to detachably connected with the rack 10 by screwing; for another example, the track 211 can be but is not limited to fixedly connected with the rack 10 by welding.

[0057] The driving member 213 is used as a power source of the driving assembly 21 to drive the connecting frame 212 to move along the preset direction MM' of the track 211. Here, the specific form of the driving member 213 is not limited, and the designer can reasonably design according to actual needs; for example, the driving member 213 can be a driving motor (not shown in the figure), at this time, the output shaft of the driving motor is fixedly connected with the screw rod, the screw rod is rotationally connected with the track 211, and the connecting frame 212 is threadedly connected with the screw rod; for another example, the driving member 213 can also be a driving handle, at this time, the driving handle is fixedly connected with the screw rod, the screw rod is rotationally connected with the track 211, and the connecting frame 212 is threadedly connected with the screw rod.
