Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a laser engraving machine. Background Technology

[0002] Laser engraving machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, by causing chemical and physical changes in the surface material through light energy to create marks, or by burning away part of the material with light energy to reveal the desired pattern or text.

[0003] When processing automotive parts, laser engraving machines are typically used to meet the automotive industry's comprehensive requirements for permanent traceability, extremely high precision, wide applicability, high efficiency and automation, and environmental protection and energy saving.

[0004] When processing automotive parts using laser engraving machines, they usually need to be fixed before laser processing. However, the commonly used fixing devices will block part of the automotive parts during fixing. When this part needs to be engraved, the fixing device can only be removed. At this time, the vibration generated by the operation of the whole device will cause instability of the automotive parts, making it easy to engrave defective products. Therefore, this utility model proposes a laser engraving machine. Utility Model Content

[0005] The purpose of this utility model is to provide a laser engraving machine to solve the problem mentioned in the background art that the existing laser engraving machine fixing device will block part of the car parts when fixing, which will cause the fixing device to need to be moved and cause instability of the car parts.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The laser engraving machine shown includes a laser engraving machine frame 1, with a support plate 101 inside the frame 1. The top surface of the support plate 101 is provided with a picking device for moving automotive parts. The top surface of the support plate 101 is provided with a conveying device 2, which includes a guide rail 10 fixed to the top surface of the support plate 101. The top surface of the guide rail 10 is provided with a support member that moves along the guide rail 10. The support member is provided with a detection sensor 16. The two sides of the support member are provided with clamping devices for fixing automotive parts. The two clamping devices are provided with two parallel pressing members 21. The clamping devices are provided with a driver that drives the pressing members 21 to rotate synchronously. One side of the guide rail 10 is provided with a driving device for moving the support member. The top surface of the laser engraving machine frame 1 is provided with a laser emitter 6, and the outer wall of the laser engraving machine frame 1 is provided with a control panel 7.

[0022] In use, the automotive parts are first placed on the conveying device 2, and then fixed on the conveying device 2 by the clamping device. After fixing, the parts are moved to the bottom of the laser emitter 6 for engraving. It should be noted that the detection sensor 16 will detect whether the orientation of the automotive parts is correct. If it is incorrect, the control panel 7 will provide an alarm message and processing will be impossible. In addition, if the laser emitter 6 needs to process the part of the automotive parts that is blocked by the lower pressing member 21, the lower pressing member 21 will be rotated at an angle, and the blocked part will be exposed. The other lower pressing member 21 will fix the automotive parts.

[0023] like Figure 2 As shown, the support includes a slider 12 that is slidably connected inside the cavity of the guide rail 10. A horizontal plate 13 is fixedly connected to the top surface of the slider 12. A detection sensor 16 is fixedly installed on the top surface of the horizontal plate 13. Two support plates 14 are fixedly connected to the top surface of the horizontal plate 13. A limit block 15 is fixedly connected to one end of the support plate 14.

[0024] The automotive parts are placed on two support plates 14, and the limit block 15 prevents the automotive parts from slipping off the support plates 14. It should be noted that the height of the detection sensor 16 fixed on the horizontal plate 13 is lower than the thickness of the support plate 14. The detection sensor 16 can be a MRON E3ZG-T61A photoelectric sensor.

[0025] like Figure 2 and Figure 3 As shown, the clamping device includes collars 18 fixed on both sides of the support plate 14. A square tube 19 is slidably connected inside the collar 18. The bottom ends of the two square tubes 19 are fixedly connected to a movable plate 17 that can move up and down. The square tubes 19 are located below the lower pressing member 21. One end of the movable plate 17 is fixedly connected to the driver. Both lower pressing members 21 include a circular plate rotatably connected to the top of the square tube 19 and a pressure rod fixedly connected to the side of the circular plate. The two pressure rods are placed in parallel.

[0026] To address the issue that existing laser engraving machine fixing devices sometimes obstruct automotive parts during installation, requiring the device to be moved and causing instability, this new invention addresses this problem. First, a driver rotates two lower pressure members 21, aligning the pressure rod with the side of the support plate 14. Then, a moving plate 17 moves the square tube 19 upwards, which in turn moves the lower pressure members 21 upwards until they are positioned on the top surface of the automotive part. Notably, at this point, the driver deflects the lower pressure members 21. Only two... The angle at which one of the pressing parts 21 is deflected is such that it can press the automotive parts when the pressing part 21 moves downward. If one of the pressing parts 21 blocks the area to be engraved, the moving plate 17 drives the square tube 19, which in turn drives the pressing part 21 to move upward. The other pressing part 21 is then deflected in the opposite direction to be above the automotive parts. Finally, the pressing part 21 is pressed down to fix the automotive parts. At this point, the area blocked by the pressing part 21 is exposed and can be engraved. It is worth noting that the bottom surface of the pressing part 21 is covered with a rubber layer to prevent deformation of the parts when they are pressed down.

[0027] like Figure 3 and Figure 4 As shown, the driver includes a servo motor 20 fixed to one end of the moving plate 17. The output end of the servo motor 20 is fixedly connected to a transmission rod 26. The rod wall of the transmission rod 26 is fixedly sleeved with a drive gear 22 located in the inner cavity of the square tube 19. The bottom end of the circular plate of the pressing member 21 is fixedly connected to a rotating rod 24 that is rotatably connected to the moving plate 17. The rod wall of the rotating rod 24 is fixedly sleeved with a driven gear 25 that meshes with the drive gear 22.

[0028] When the driver drives the pressing component 21 to rotate, the servo motor 20 is started first, which drives the transmission rod 26 to rotate. The transmission rod 26 drives the drive gear 22 to rotate. The rotation of the drive gear 22 drives the meshing driven gear 25 to rotate. Finally, the driven gear 25 drives the rotating rod 24 and the pressing component 21 at the top of the rotating rod 24 to rotate.

[0029] like Figure 3 As shown, a connecting plate is fixedly connected to one end of the slider 12, and a micro cylinder 23 is fixedly connected to the top surface of the connecting plate. The output end of the micro cylinder 23 is fixedly connected to the bottom surface of the moving plate 17.

[0030] The micro cylinder 23 enables the moving plate 17 to move up and down. When moving up, it is convenient to adjust the angle of the pressing member 21. When pressing down, it can drive the pressing member 21 to move down to fix the automotive parts.

[0031] like Figure 2As shown, the driving device includes a servo motor 8 fixed on the top surface of the bearing plate 101. The output end of the servo motor 8 is fixedly connected to a coupling 9. One end of the coupling 9 is fixed to a lead screw 11. The slider 12 is threaded onto the rod wall of the lead screw 11. One end of the lead screw 11 is rotatably connected to the limiting plate at the top of the guide rail 10.

[0032] When the drive unit is in operation, the servo motor 8 is started first, which drives the coupling 9 to rotate. The coupling 9 drives the lead screw 11 to rotate, and the slider 12, which is threadedly connected to the lead screw 11, moves along the guide rail 10, thereby driving the support component that carries the automotive parts to move.

[0033] like Figure 1 As shown, a limiting groove 102 is provided on the top surface of the support plate 101. The picking device includes a three-finger gripper 4 disposed inside the limiting groove 102. An electric slide 3 for driving the three-finger gripper 4 to move is provided on the bottom surface of the support plate 101. The electric slide 3 is located on the bottom surface of the support plate 101.

[0034] The electric slide 3 drives the three-finger gripper 4 to move. After the automotive parts are processed, the three-finger gripper 4 can grab the automotive parts. The electric slide 3 drives the three-finger gripper 4 to move out of the support component that holds the automotive parts.

[0035] like Figure 1 As shown, the control module inside the control panel 7 is connected to the three-finger gripper 4, electric slide 3, servo motor 8, detection sensor 16, servo motor 20 and miniature cylinder 23 via electrical signals. The control module can be a DAM-3232 control module. In addition, the control panel 7 can control the operation of the internal machinery and intuitively observe the processing progress.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
