Description

Technical Field

[0001] This application relates to the field of laser marking technology, and in particular to a high-efficiency laser marking device. Background Technology

[0002] Laser marking is increasingly widely used in the marking industry, such as for PCB boards and copper-clad laminates. The production process requires processes like edge QR code marking and pre-defined marking. Currently, there is a batch of board-shaped products where incoming materials are stacked in material boxes, one box holding one product. Each layer of products has a separating paper surface for dust prevention and protection. These products come in various sizes, each with different marking positions and patterns. Currently, no fully automated marking equipment can meet all these marking requirements.

[0003] Compared to actual use, one type of existing laser marking equipment places multiple workpieces on top of the conveyor mechanism and marks the workpiece surface through self-identification by the marking equipment. However, when the volume of the workpiece is larger than the recognition range of the recognition structure, the position to be marked needs to be manually adjusted by the operator, which prolongs the processing and reduces the marking efficiency.

[0004] Therefore, in order to solve the above problems, this application provides a high-efficiency laser marking device.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0019] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0020] Example 1

[0021] Reference Figures 1-3 A high-efficiency laser marking device includes a processing table 1. The device is characterized by: a transmission motor 18 mounted on the outer side of one end of the processing table 1 via a base; a conveyor belt 2 mounted on the inner side of the processing table 1 via a rotating shaft; a marking support frame 3 provided on the outer side of one end of the processing table 1; a laser marking device 4 mounted on one side of the top of the marking support frame 3; a lateral adjustment screw 5 rotatably connected to one end of the processing table 1 to achieve the marking function; a lateral support plate 7 rotatably connected to one end of the lateral adjustment screw 5; two lateral adjustment stabilizing rods 6 welded to both sides of one end of the lateral support plate 7 to adjust, fix, and limit the lateral position of the workpiece; one end of the two lateral adjustment stabilizing rods 6 extending through to the outer side of the processing table 1; and a positioning cylinder 8 mounted on the outer side of one end of the processing table 1 via a base. A gathering groove is formed on the outer surface of one end of the positioning cylinder 8. 9. The extension end of the positioning cylinder 8 is connected to a clamping plate 10. In order to adjust, limit and fix the vertical position of the workpiece, the length of the limiting main plate 12 is greater than the width of the clamping plate 10. In order to prevent the limiting main plate 12 from hitting the clamping plate 10 when flipping, a limiting motor 11 is installed on the outer side of one end of the clamping plate 10 through the base. The transmission end of the limiting motor 11 is welded to the limiting main plate 12. A vertical adjusting screw 13 is rotatably connected to one end of the limiting main plate 12. A vertical plate 14 is rotatably connected to one end of the vertical adjusting screw 13. A vertical stabilizing rod 15 is welded to the outer side of one end of the vertical plate 14. One end of the vertical stabilizing rod 15 extends through to the outer side of the limiting main plate 12. A flipping rod 16 is rotatably connected to the outer side of one end of the laser marking device 4. In order to provide a reference for horizontal adjustment, a calibrating rod 17 is rotatably connected to the outer side of one end of the flipping rod 16.

[0022] Working principle: First, the operator adjusts the transverse limiting mechanism according to the marking position of the workpiece. The operator first measures the distance from the marking position on the wide surface of the workpiece to the far edge on one side. Then, the operator flips the rotating rod 16 connected to the middle of the outer side of one end of the laser marking equipment 4 to a vertical state. Then, the operator flips the folded alignment rod 17 on the inner side of the rotating rod 16 to a parallel state. Then, the operator rotates the transverse adjusting screw 5. At that time, the transverse adjusting screw 5 will rotate and move on the outer side of one end of the processing table 1, pushing the transverse abutment 7 connected to one end to move. During this period, the two transverse adjusting stabilizing rods 6 welded on both sides of one end of the transverse abutment 7 can provide stability for the movement of the transverse abutment 7. Since the transverse abutment 7 is directly below the alignment rod 17, after the position of the transverse abutment 7 is at the middle of the laser marking equipment 4, which is the distance from the marking position on the wide surface of the workpiece to the far edge on one side, the operator stops rotating the transverse adjusting screw 5 and then resets the rotating rod 16 and the alignment rod 17.

[0023] The operator then determines the distance from the marking position on the long surface of the workpiece to its nearest edge. Next, the operator rotates the vertical adjusting screw 13. The screw, supported by the clamping plate 10, moves the vertically connected vertical abutment 14 until the distance between the vertical abutment 14 and the laser marking equipment 4 equals the distance from the marking position on the long surface of the workpiece to its nearest edge. The operator then stops rotating the vertical adjusting screw 13 and starts the conveyor motor 18. The conveyor motor 18 drives the conveyor belt 2 mounted on the rotating shaft. Once the laser marking equipment 4 scans a workpiece passing by, the control terminal activates the limit motor 11, which then drives the conveyor belt 2... The clamping plate 10 connected to the moving end flips until one end of the clamping plate 10 is attached to the top surface of the conveyor belt 2. At this time, the vertical plate 14 connected to the clamping plate 10 through the vertical adjusting screw 13 flips, thereby blocking the workpiece at the top of the conveyor belt 2. Then, the control terminal starts the positioning cylinder 8, which pushes the clamping plate 10 connected to its extension end to move until the other side of the workpiece is attached to the horizontal plate 7. Then, the control terminal shuts off the conveyor motor 18 and starts the laser marking device 4 to mark the top surface of the workpiece. The position at this time corresponds to the bottom of the laser marking device 4. Then, the cycle is repeated to process the workpiece. This design can make the workpiece processing process faster.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
