Technical Field

[0001] This utility model relates to the field of laser marking equipment technology, and in particular to an automatic laser marking device. Background Technology

[0002] Laser marking technology uses a laser beam to print permanent marks on the surface of various materials to indicate information such as the production date, model, and category of a product. It can also achieve product traceability by processing patterns such as QR codes and barcodes.

[0003] Currently, Chinese Patent Publication No. CN207447615U discloses an automatic laser marking machine that solves the problem of wasted manpower in traditional laser marking machines. The key technical point of this automatic laser marking machine is that it includes an installation platform, a limiting baffle fixed to one side of the installation platform, a conveying and positioning component installed on the other side of the installation platform, and a laser marking head located above the installation platform. A conveying channel is formed between the limiting baffle and the conveying and positioning component. A feeding station, a marking station, and a discharging station are sequentially arranged on the conveying channel. The side of the conveying and positioning component facing the limiting baffle has a positioning groove for the lead screw nut to engage. The automatic laser marking machine also includes a longitudinal sliding component and a transverse sliding component.

[0004] Although the automatic laser marking machine can automatically mark workpieces, during use, the marking laser head is located at a fixed end, and each workpiece needs to be transported to the marking laser head for packaging. The structure is relatively cumbersome, the laser marking efficiency is low, and it is difficult to automatically collect the workpieces after marking. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a laser automatic marking device to solve the problem of low marking efficiency in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an automatic laser marking device, including a frame, a conveyor belt horizontally arranged on the frame for conveying workpieces, and a laser marking head arranged above the conveyor belt. The frame is provided with an identification component capable of identifying the position of each workpiece on the conveyor belt and a position adjustment mechanism electrically connected to the identification component to drive the laser marking head to move along the width direction of the conveyor belt. It also includes a receiving rack arranged at the end of the conveyor belt and a feeding conveying mechanism that can transport workpieces one by one to the receiving rack.

[0007] By adopting the above technical solution, the workpiece can be fed horizontally by the conveyor belt. During the conveying process, the workpiece position is identified and positioned by the identification component. When the workpiece enters the marking station, the identification component is linked with the position adjustment component to move the laser marking head to the upper side of the workpiece for marking. After the workpiece is marked, it is automatically unloaded and collected on the receiving rack by the conveyor belt and the unloading conveyor mechanism, realizing automated marking and unloading of workpieces and improving the marking efficiency of workpieces.

[0008] In one embodiment of the present invention, the position adjustment mechanism includes a support arranged along the width direction of the conveyor belt, a sliding seat fixedly connected to the side wall of the laser marking head and slidably connected to the support, and a first driving member arranged on the support to drive the sliding seat to move along the extension direction of the support.

[0017] By adopting the above technical solution and using multiple suction nozzles, the workpiece can be stably picked up from the end of the conveyor belt, making the connection more reliable when the robotic arm grasps it and not affecting the structure of the workpiece itself.

[0018] In one embodiment of the present invention, the support plate is provided with an adjustment component for adjusting the position of the suction nozzle. The adjustment component includes a second sliding groove on the support plate corresponding to the suction nozzle and an adjustment nut that is threaded to the outside of the suction nozzle and can abut against the support plate.

[0020] In one embodiment of the present invention, two limiting guide plates are respectively disposed on both sides of the conveyor belt along the width direction of the conveyor belt, and the adjusting plate is also provided with a first slide groove that can adjust the relative spacing between the limiting guide plates. The first slide groove extends along the width direction of the conveyor belt and multiple slide grooves are arranged in an array along the conveying direction of the conveyor belt, and each first slide groove is provided with an adjusting bolt.

[0021] By adopting the above technical solution, the relative distance between the two limiting guide plates can be adjusted, making them adaptable to workpieces of different widths.
