[0002] Laser cleaning machine refers to a process that uses high-energy laser beams to irradiate the surface of a workpiece, causing dirt, rust or coating on the surface to evaporate or peel off instantly, and quickly and effectively removes the surface attachments or surface coatings of the cleaning object, thereby achieving a clean process. When using a laser cleaning machine, in order to improve the convenience of cleaning the surface of the workpiece, a cleaning machine that is easy to position is required. The currently commonly used laser cleaning machine clamps the material through a fixed module, and then irradiates the laser from top to bottom.

[0003] For example, publication number CN202223208261.1, a laser cleaning with stable positioning. The above patent has the following shortcomings in actual use:

[0004] The device clamps the material through the stabilizing components on both sides of the base surface, and then controls the laser mechanism located on the top of the stabilizing component to irradiate the surface of the material with laser to achieve the cleaning effect. However, the efficiency of one-to-one fixed cleaning is low, and the debris cleared by the laser irradiation on the surface of the material is easy to fly away, thereby coming into contact with the device and the operator, posing a safety hazard. Utility Model Content

[0005] In order to improve the problem that conventional laser cleaning machines have low cleaning efficiency and cannot effectively collect debris, posing a potential safety hazard, the present application provides a high-speed laser flying galvanometer cleaning machine.

[0037] The following is combined with Figure 1 —5 further describes this application in detail.

[0038] The embodiment of the present application discloses a high-speed laser flying galvanometer cleaning machine.

[0039] Example 1

[0040] Reference Figure 1 A high-speed laser flying galvanometer cleaning machine comprises a main chassis 1, a cavity is provided inside the main chassis 1, a chassis door 12 is rotatably provided at the middle part of the front end of the side surface of the main chassis 1, the chassis door 12 can be movably opened and closed and is connected to the inside of the cavity of the main chassis 1, and at the same time, heat dissipation windows 11 are provided on both sides of the side surface of the main chassis 1 on both sides of the chassis door 12, the two heat dissipation windows 11 penetrate the side wall and are connected to the inside of the cavity of the main chassis 1, and an operation switch 10 is fixedly provided on the side of one of the heat dissipation windows 11 away from the chassis door 12, a mechanical arm 8 is rotatably connected to the side of the main chassis 1 adjacent to the operation switch 10, the mechanical arm 8 can be raised and lowered and rotated, and a display screen 9 is fixedly connected to the top of the mechanical arm 8.

[0041] It should be noted that a computer control system and an electrical supply system and other structures are installed in the cavity of the main chassis 1. At the same time, the operating switch 10 is electrically connected to the computer control system and the electrical supply system and other structures through lines, and real-time feedback is provided to the display screen 9. Since the computer control system and the electrical supply system and other structures are existing conventional technologies, their structural principles will not be described in detail.

[0042] Through the above arrangement, the opened chassis cabinet door 12 is convenient for personnel to maintain and replace the internal structure of the main chassis 1. At the same time, when the device is started, the electrical heat generated by the operation of the internal structure of the main chassis 1 is discharged to the outside through the heat dissipation window 11 to prevent the device from being damaged due to overheating.

[0043] Reference Figure 1 , 2 Three connecting columns 2 are screwed on both sides of the upper end surface of the main chassis 1, and the tops of the connecting columns 2 on both sides are fixedly connected to the bottom of the shell of the X-axis moving mechanism 3, the screw surfaces of the two X-axis moving mechanisms 3 are threadedly connected with matching connecting plates 13, and the tops of the connecting plates 13 are fixedly connected to the bottom of the shell of the Y-axis moving mechanism 4 by screws, the screw surface of the Y-axis moving mechanism 4 is also threadedly connected with a matching connecting plate 13, and the connecting plate 13 of the Y-axis moving mechanism 4 is fixedly connected to the shell of the Z-axis moving mechanism 5 on one side close to the center of the main chassis 1, the screw surface of the Z-axis moving mechanism 5 is threadedly connected with a matching connecting plate 13, and the end face of the connecting plate 13 of the Z-axis moving mechanism 5 faces the center of the main chassis 1.

[0044] It should be noted that the X-axis moving mechanism 3, the Y-axis moving mechanism 4 and the Z-axis moving mechanism 5 are all fixedly connected with adapted motors, and the power supply end of the motor is configured with a corresponding electrical supply system. At the same time, in the subsequent description, the three connecting plates 13 are divided into three directions of bottom, top and front corresponding to the connection relationship of the X-axis moving mechanism 3, the Y-axis moving mechanism 4 and the Z-axis moving mechanism 5.

[0045] Through the above arrangement, the lead screws of the two X-axis moving mechanisms 3 rotate to drive the connecting plate 13 located below to translate along the X-axis, and the connecting plate 13 located below drives the shell of the Y-axis moving mechanism 4 to reciprocate along the X-axis. At the same time, the lead screw of the Y-axis moving mechanism 4 rotates to drive the connecting plate 13 located above to translate along the Y-axis, and the connecting plate 13 located above drives the shell of the Z-axis moving mechanism 5 to reciprocate along the Y-axis. When the lead screw of the Z-axis moving mechanism 5 rotates, it drives the connecting plate 13 located in the front to move up and down along the Z-axis. Therefore, the X-axis moving mechanism 3, the Y-axis moving mechanism 4 and the Z-axis moving mechanism 5 are integrated into one, so that the connecting plate 13 located in the front has the function of multi-axis movement at the same time.

[0046] Reference Figure 1 , 3 The cleaning mechanism 6 includes a laser galvanometer lens 61 fixed on the outer surface of the front connecting plate 13, a fixing plate 62 is welded and fixed to one end of the side surface of the laser galvanometer lens 61, a through hole is provided in the middle of the fixing plate 62 and the through hole is connected to the access end of the laser galvanometer lens 61, a connecting piece 63 is fixed to the side surface of the fixing plate 62 away from the laser galvanometer lens 61, and the connecting hole in the middle of the connecting piece 63 is aligned with the through hole of the fixing plate 62, the connecting piece 63 has a through hole and is connected and fixed to an adjusting mechanism 64, an optical fiber is fixed to the top of the adjusting mechanism 64, and a visual CCD module 65 is fixed to the end screw of the side surface of the connecting piece 63 adjacent to the adjusting mechanism 64.

[0047] It should be noted that the optical fiber at the top of the adjustment mechanism 64 is connected to the laser generator, so that the laser is transmitted to the inside of the connector 63 to facilitate subsequent laser cleaning operations. At the same time, a refraction mirror for refracting the laser is provided in the through hole of the connector 63.

[0048] Through the above arrangement, the optical fiber transmits the laser to the inside of the adjustment mechanism 64. During this process, the personnel focus or diverge the transmitted laser by debugging the button outside the adjustment mechanism 64 to control the laser intensity. The laser is shot into the connecting piece 63 and contacts the refractor, thereby making a 90° turn and shooting into the laser galvanometer lens 61, and finally contacts the material to perform the cleaning operation. At the same time, the visual CCD module 65 is docked with the computer control system and moves synchronously with the connection plate 13 located in the front, thereby transmitting the laser orientation information to the computer system, which is convenient for personnel to fine-tune the laser coordinates and helps to improve the cleaning accuracy.

[0049] Reference Figure 1 , 4 5. A cleaning base 14 is fixedly provided at the middle of the upper end surface of the main chassis 1. The rotating mechanism 7 includes two fixing columns 71 fixedly provided on the upper end surface of the cleaning base 14 (the fixing columns 71 are arranged in groups of two, and there are at least six groups). A cleaning table 72 is rotatably provided between two of the multiple groups of fixing columns 71 on the upper end surface of the cleaning base 14. Two fixing washers 73 are fixed to the upper end surfaces of the multiple fixing columns 71 with screws, and a rotating fixture 74 is rotatably connected between the two fixing washers 73.

[0050] It should be noted that the multiple cleaning tables 72 are movable through the bottom of the cleaning base 14 and connected to the output end of the motor through gears, connecting rods and other structures to achieve synchronous rotation. Since the connection between gears and connecting rods to achieve rotation is not the main technology, its structural principle will not be described in detail.

[0051] Through the above arrangement, the cleaning base 14 provides a fixed fulcrum for the fixed column 71 and the cleaning table 72. At the same time, the cleaning table 72 rotates to drive the material placed on the surface of the cleaning table 72, so that the material rotates while being cleaned by the laser, thereby increasing the cleaning area and improving the cleaning effect.

[0052] Reference Figure 1 , 5The middle parts of both sides of the rotating clamp 74 are rotatably connected with force-bearing plates 75. The top materials of the two force-bearing plates 75 are hardened rubber materials, which have a certain deformation while retaining hardness to play a supporting role. The tops of the two force-bearing plates 75 are fixedly connected with downward pressing mechanisms 76. The middle parts of the opposite sides of the two force-bearing plates 75 are rotatably connected with an amplifying hub 77. The top of the amplifying hub 77 is hook-shaped and abuts against the middle part of the lower end surface of the downward pressing mechanism 76. At the same time, the bottom of the amplifying hub 77 is rotatably connected with two fixed gaskets 1 73. The side of the rotating clamp 74 away from the amplifying hub 77 is set as a ring, and a dust suction pipe 78 is movably inserted on the inner surface of the ring. The upper and lower ends of the surface of the dust suction pipe 78 are threadedly connected with fixed gaskets 2 79, and the two fixed gaskets 2 79 are respectively fixed to the upper and lower ends of the ring of the rotating clamp 74.

[0053] Through the above arrangement, the pressing mechanism 76 applies pressure to the two force-bearing plates 75, and the rubber parts on the top of the two force-bearing plates 75 are squeezed downward by the pressure. As the pressing mechanism 76 is pressed in, pressure is applied to the amplifying hub 77, so that the amplifying hub 77 rotates clockwise around the connection point of the two fixed gaskets 73, thereby amplifying the rotational force to the two force-bearing plates 75. At this time, the force-bearing plates 75 are subjected to pressure from the top and tension from the sides, so that they rotate counterclockwise around the connection point of the two fixed gaskets 73, thereby applying pressure to the rotating clamp 74, which presses the rotating clamp 74 downward, shortening the distance between the dust suction tube 78 and the surface of the material, and facilitating the absorption of debris cleaned by the laser.

[0054] Among them, the device also includes an X-axis moving mechanism 3, a Y-axis moving mechanism 4, a Z-axis moving mechanism 5, a laser galvanometer lens 61, a visual CCD module 65, a pressing mechanism 76 and a display screen 9, which are all existing technologies and their structural principles will not be described in detail.

[0055] The implementation principle of a high-speed laser flying galvanometer cleaning machine in the embodiment of the present application is as follows: when using the device, the material to be cleaned needs to be placed on the surface of the cleaning table 72, and the motor device at the bottom of the cleaning table 72 is started, so that the cleaning table 72 drives the material to rotate, and then the personnel controls the operation of the X-axis moving mechanism 3, the Y-axis moving mechanism 4, and the Z-axis moving mechanism 5 by debugging the operating switch 10;

[0056] When the lead screw in the X-axis moving mechanism 3 rotates, it drives the connecting plate 13 located below to translate along the X-axis, and then the connecting plate 13 below drives the housing of the Y-axis moving mechanism 4 to reciprocate along the X-axis;

[0057] When the lead screw in the Y-axis moving mechanism 4 rotates, it drives the connecting plate 13 located above to perform Y-axis translation, and then the connecting plate 13 above drives the housing of the Z-axis moving mechanism 5 to reciprocate along the Y-axis;

[0058] When the lead screw in the Z-axis moving mechanism 5 rotates, it drives the connecting plate 13 in the front to perform Z-axis translation, and then the connecting plate 13 in the front drives the laser galvanometer lens 61 to perform reciprocating lifting and lowering movement along the Z-axis. At the same time, due to the three-way linkage of the X-axis moving mechanism 3, the Y-axis moving mechanism 4 and the Z-axis moving mechanism 5, the laser galvanometer lens 61 finally has the effect of multi-axis synchronous movement at the same time. When the laser emission port of the laser galvanometer lens 61 moves to the top of the material, the laser irradiation cleans the surface of the material;

[0059] As the laser cleans the surface of the material and produces debris, the operator controls the pressing mechanism 76 to start by operating the switch 10, thereby applying pressure to the force-bearing plate 75, causing the rotating clamp 74 to rotate counterclockwise, thereby driving the dust suction pipe 78 to be pressed downward to shorten the distance to the material surface. When the dust suction pipe 78 is pressed into the dust suction range, the operator controls the fan and other devices on the top of the dust suction pipe 78 to exhaust air, thereby absorbing the debris on the surface of the material and removing it into the storage mechanism to prevent the debris from flying and causing safety hazards.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
