Description

Technical Field

[0001] The present invention relates to the technical field of laser marking machines, and particularly to an automatic feeding platform vision positioning laser marking machine. Background Art

[0002] Laser marking machines can quickly engrave patterns on the surfaces of various materials, so they are widely used in the production and processing of various equipment. When used with an automatic feeding platform, conventional laser marking machines need to perform marking processing through vision positioning. However, once some workpieces are stacked, normal laser marking processing cannot be carried out, so manual auxiliary material placement is still required. On the other hand, since a large number of transmission components are provided on the tops of the laser head and the vision camera, once impurities fall on the surface, they will affect the movement of the laser head, thus easily causing an angular error. This error will cause the laser marking to shift, affecting the quality of the finished product. Conventional laser marking machines cannot shield the top and lack effective protection. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an automatic feeding platform vision positioning laser marking machine to solve the problems raised in the above background art. The present invention can automatically level the stacked materials and avoid blockage, can shield and protect the moving shaft part, prevent dust from floating in, and ensure the accuracy of marking.

[0004] To achieve the above purpose, the present invention is realized through the following technical solutions: An automatic feeding platform vision positioning laser marking machine includes a laser marking machine body. The laser marking machine body includes a frame, a blocking rod, a feeding rod, a vision camera, and a laser head. The frame is fixed on both sides of the conveyor table through support columns on both sides. One side of the support column is provided with a motor one. The output end of the motor one is provided with a driving gear. The driving gear meshes with a driven gear. The driven gear is respectively sleeved on one end of the blocking rod and the feeding rod. A moving horizontal axis and a moving vertical axis are arranged inside the frame. The laser head and the vision camera are installed at the bottom of the moving vertical axis.

[0005] In this embodiment, the moving horizontal axis and the moving vertical axis are connected through a bracket. Both sides of the laser head are connected to a pull rod through a connecting mechanism. The two ends of the pull rod are provided with rollers. The pull rod is installed inside the chute through the rollers.

[0006] In this embodiment, the chute is opened on both sides of the inner wall of the frame. A sliding rod is arranged in the middle of the pull rod. The moving distance of the moving vertical axis is the same as the length of the sliding rod. The laser head is sleeved on the surface of the sliding rod through metal plates on both sides.

[0007] In this embodiment, a protective film is connected to the surface of the pull rod, and the other end of the protective film is wound inside the reel. The housing part of the reel is fixedly installed on the inner wall of the frame.

[0008] In this embodiment, a support plate is provided at the other ends of the stop rod and the feeding rod. The top end of the support plate is integrally fixed with the support column, and the other end of the support plate is installed in the middle fixed area of the transfer table.

[0009] In this embodiment, the stop rod and the feeding rod are installed in parallel and both are in a horizontal state. The surface of the stop rod is smooth, and the surface of the feeding rod is provided with concave and convex patterns.

[0010] In this embodiment, the moving horizontal axis and the moving vertical axis are perpendicular to each other. The moving vertical axis passes through the housing of the frame and is connected to the external motor II. The other end of the moving vertical axis is installed in the housing of the frame through a bearing.

[0011] In this embodiment, a gap is provided in the middle of the transfer table. The feeding rod is installed inside the gap, and the top of the feeding rod is flush with the surface of the transfer table.

[0012] The beneficial effects of the present invention: An automatic feeding platform vision positioning laser marking machine of the present invention includes a laser marking machine body. The laser marking machine body includes a support column, a frame, a transfer table, a motor I, a stop rod, a feeding rod, a motor II, a chute, a reel, a protective film, a support plate, a driving gear, a driven gear, a moving vertical axis, a bracket, a moving horizontal axis, a vision camera, a laser head, a pull rod, a roller, and a sliding rod.

[0013] 1. By setting the stop rod to a height from the transfer table greater than the thickness of a single workpiece but less than the thickness of two stacked workpieces, the automatic feeding platform vision positioning laser marking machine can block the stacked workpieces once they occur and push off the top workpiece. At the same time, the transmission of the motor I can quickly push off the top workpiece in the reverse direction while blocking.

[0014] 2. A gap is provided in the middle of the transfer table of the automatic feeding platform vision positioning laser marking machine. The feeding rod is placed in the gap, and by using the feeding rod to rotate in the same direction as the transfer table, the workpieces piled up on the surface can be vibrated to avoid jamming, accelerate the dredging of the workpieces, and cooperate with the stop rod to place the randomly placed workpieces horizontally and individually one by one for delivery.

[0015] 3. The moving horizontal axis and the moving vertical axis at the top of the laser head of the automatic feeding platform vision positioning laser marking machine are blocked by the protective film. Therefore, when the laser head moves, the protective films on both sides can be driven to move synchronously by the pull rod, so as to always block the transmission structure at the top and reduce the probability of dust floating into the inside.

Detailed implementation manners

[0021] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a vision positioning laser marking machine for an automatic feeding platform, including a laser marking machine body. The laser marking machine body includes a frame 2, a stop bar 5, a feeding rod 6, a vision camera 17 and a laser head 18. The frame 2 is fixed on both sides of the conveyor table 3 through support columns 1 on both sides. One side of the support column 1 is provided with a motor 1 4. The output end of the motor 1 4 is provided with a driving gear 12. The driving gear 12 meshes with a driven gear 13. The driven gear 13 is respectively sleeved on one end of the stop bar 5 and the feeding rod 6. A moving horizontal axis 16 and a moving vertical axis 14 are arranged inside the frame 2. The bottom of the moving vertical axis 14 is provided with a laser head 18 and a vision camera 17. Place the workpiece on the conveyor table 3 and move it to the bottom of the laser head 18 for marking treatment, and then it can be sent out along with the conveyor table 3 to complete.

[0023] In this embodiment, the moving horizontal axis 16 and the moving vertical axis 14 are connected by a bracket 15. Both sides of the laser head 18 are connected by a connecting mechanism and a pull rod 19. Rollers 20 are installed at both ends of the pull rod 19. The pull rod 19 is installed inside the chute 8 through the rollers 20. After the visual camera 17 captures the real-time position of the workpiece, the moving horizontal axis 16 and the moving vertical axis 14 move under the control of an external control device, so as to align the laser head 18 with the surface of the workpiece to achieve marking processing. When the laser head 18 moves, it will drive the pull rod 19 to move longitudinally synchronously.

[0024] In this embodiment, the chute 8 is opened on both sides of the inner wall of the frame 2. A sliding rod 21 is arranged in the middle of the pull rod 19. The moving distance of the moving vertical axis 14 is the same as the length of the sliding rod 21. The laser head 18 is sleeved on the surface of the sliding rod 21 through metal plates on both sides. Since the conveyor table 3 itself will move in the horizontal coordinate, the moving horizontal axis 16 only plays a role in correcting errors. When it is necessary to move and change the horizontal coordinate, the laser head 18 will move on the sliding rod 21.

[0025] In this embodiment, a protective film 10 is connected to the surface of the pull rod 19. The other end of the protective film 10 is wound inside a reel 9. The housing part of the reel 9 is fixedly installed on the inner wall of the frame 2. When the laser head 18 moves longitudinally for marking, while driving the pull rod 19 to move, the surface of the pull rod 19 pulls the protective film 10 to move synchronously. Finally, the protective film shields the moving horizontal axis 16 and the moving vertical axis 14 at the top, so that they avoid excessive contact with external dust, extend the cleaning frequency, and improve the service life and marking accuracy.

[0026] In this embodiment, a support plate 11 is arranged at the other ends of the stop rod 5 and the feeding rod 6. The top end of the support plate 11 is integrally fixed with the support column 1. The other end of the support plate 11 is installed in the middle fixed area of the conveyor table 3. The support plate 11 connects the other ends of the stop rod 5 and the feeding rod 6 to keep them horizontal. The stop rod 5 and the feeding rod 6 are installed parallel to each other. The surface of the stop rod 5 is smooth, and the surface of the feeding rod 6 is provided with concave and convex patterns. Since the driving gear 12 is installed in the middle of the stop rod 5 and the feeding rod 6, the stop rod 5 and the feeding rod 6 rotate in opposite directions. The stop rod 5 pushes the stacked materials backward, and the feeding rod 6 pushes the falling workpieces forward, so as to flatten the stacked workpieces and avoid jamming.

[0027] In this embodiment, the moving horizontal axis 16 and the moving vertical axis 14 are perpendicular to each other. The moving vertical axis 14 passes through the housing of the frame 2 and is connected to the external second motor 7. The other end of the moving vertical axis 14 is installed in the housing of the frame 2 through a bearing. The moving vertical axis 14 drives the components at the bottom to move in the longitudinal coordinate by the second motor 7. The moving horizontal axis 16 drives the laser head 18 and the vision camera 17 to move horizontally alone, and the moving range is short.

[0028] In this embodiment, a gap is provided in the middle of the transfer table 3. The feeding rod 6 is installed inside the gap, and the top of the feeding rod 6 is flush with the surface of the transfer table 3. The surface of the feeding rod 6 is uneven. Therefore, while the workpieces stacked at this position are transferred forward, it can also play a role in vibrating. And the flush height avoids blocking the workpieces by itself, so that the part of the transfer table 3 at this place can smoothly deliver materials.
