A closed modular fiber laser marking machine

Abstract

This invention discloses a closed modular fiber laser marking machine, comprising a main body and a fiber laser located within the main body. A gas purification device is connected to the outer wall of the main body, and a slot is provided on the outer wall of the main body. A marking box is slidably inserted into the slot, and a clamping mechanism is provided within the marking box. The gas purification device includes a purification chamber fixed to the outer wall of the main body via a connecting plate, and a storage tank containing activated carbon is fixed within the purification chamber. This invention removes odors and harmful components by venting the gas generated during the marking process and adsorbing them with activated carbon. The intermittent connection between the discharge port and the purification pipe is achieved through the continuous rotation of a cam, allowing for the intermittent discharge of activated carbon. This ensures that the activated carbon is discharged after adsorbing odors and harmful components, avoiding the problem of odors and harmful components escaping due to weakened adsorption capacity caused by continuous operation of the activated carbon and the inability to replace it in time.

Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a closed modular fiber laser marking machine. Background Technology

[0002] Fiber optic marking machines use laser beams to create permanent marks on the surfaces of various materials, revealing the desired patterns, text, barcodes, and other graphics.

[0003] Fiber optic marking primarily works by evaporating the surface material to expose the deeper material. However, the evaporation and burning of the surface material produces a pungent odor. Directly releasing this odor would cause air pollution and discomfort for workers. Therefore, continuously absorbing and removing the odor during fiber optic marking is a problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a closed modular fiber laser marking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A closed modular fiber laser marking machine includes a body and a fiber laser located inside the body. A gas purification device is connected to the outer wall of the body. A slot is provided on the outer wall of the body, and a marking box is slidably inserted into the slot. A clamping mechanism is provided in the marking box. The gas purification device includes a purification box fixed to the outer wall of the body by a connecting plate. A storage tank containing activated carbon is fixed inside the purification box. A purification pipe is connected to the lower side wall of the storage tank. An exhaust pipe is connected between the purification pipe and the body. An exhaust fan is installed on the exhaust pipe. An air outlet is also connected to the outer wall of the purification pipe. The purification pipe has a rotating column for intermittently discharging activated carbon. A discharge port is provided through the rotating column.

[0007] Preferably, the inner wall of the machine body is fixed with a Z-axis guide rail and an X-axis guide rail located on the upper side of the marking box. The Z-axis guide rail and the X-axis guide rail are both composed of a guide rail and a slider that is matched on the guide rail. The end of the X-axis guide rail is fixed to the outer wall of the slider located on the Z-axis guide rail. The fiber laser is fixed to the lower side wall of the slider located on the X-axis guide rail.

[0008] Preferably, the clamping mechanism includes a placement plate fixed inside the marking box, a clamping plate slidably disposed inside the marking box on the placement plate, a telescopic rod fixed to the inner wall of the marking box on the lower side of the placement plate, a push plate arranged in a "∩" shape fixed to the driving end of the telescopic rod, a circular plate fixed to the lower side wall of each clamping plate by a fixing rod, an inclined surface on the inner wall of the push plate that contacts the outer wall of the circular plate, and a sliding groove provided at the connection between the placement plate and the fixing rod.

[0009] Preferably, a connecting groove is fixed inside the purification chamber, a sliding plate is slidably disposed inside the connecting groove, a motor is fixed to the inner wall of the connecting groove, a cam is fixed to the drive end of the motor, a connecting rod is rotatably connected between the front side wall of the end of the cam and the upper side wall of the sliding plate, a vertical rod is fixed to the lower side wall of the sliding plate, a lever is rotatably connected to the lower end of the vertical rod via a torsion spring shaft, a pawl is fixed to the end of the lever, a ratchet is rotatably installed inside the purification chamber, the end of the pawl contacts the outer wall of the ratchet, a rotating rod is fixed to the outer wall of the rotating column, pulleys are fixed to the outer walls of both the rotating rod and the ratchet, a belt is sleeved between the two pulleys, a bearing is fixedly embedded at the connection between the purification tube and the rotating rod, and the rotating rod passes through the bearing and is fixedly connected to the inner ring of the bearing.

[0010] Preferably, a guide rod is slidably inserted into the upper side wall of the purification box, and a horizontal plate located on the upper side wall of the cam and in contact with the outer wall of the cam is fixed at the upper end of the guide rod. A pressing rod is fixed at the end of the horizontal plate, and a switch located below the end of the pressing rod is fixed on the upper side wall of the connecting plate. A solenoid valve connected to the switch is installed on the outer wall of the exhaust pipe.

[0011] Preferably, a rubber pad is fixedly embedded on one side of each of the two clamping plates.

[0012] Compared with existing technologies, the advantages of this enclosed modular fiber laser marking machine are:

[0013] This invention removes the gas generated during the marking process by venting it out and adsorbing and removing odors and harmful components with activated carbon. The continuous rotation of the cam enables intermittent connection between the discharge port and the purification pipe, allowing the activated carbon to be discharged intermittently. This avoids the problem of odors and harmful components escaping due to the weakening of the adsorption capacity of activated carbon caused by continuous operation and the inability to replace it in time.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Reference Figure 1-5 A closed modular fiber laser marking machine includes a body 1 and a fiber laser 7 located inside the body 1. The inner wall of the body 1 is fixed with a Z-axis guide rail 5 and an X-axis guide rail 6 located on the upper side of the marking box 4. Both the Z-axis guide rail 5 and the X-axis guide rail 6 are composed of guide rails and sliders that are matched on the guide rails. The end of the X-axis guide rail 6 is fixed to the outer wall of the slider located on the Z-axis guide rail 5. The fiber laser 7 is fixed to the lower side wall of the slider located on the X-axis guide rail 6. The fiber laser 7 is driven to move on the Z-axis and X-axis by the Z-axis guide rail 5 and the X-axis guide rail 6 to realize multi-directional laser marking work.

[0023] A gas purification device is connected to the outer wall of the machine body 1. A slot 3 is opened on the outer wall of the machine body 1. A marking box 4 is slidably inserted into the slot 3. A clamping mechanism is provided inside the marking box 4. The clamping mechanism includes a placement plate fixed inside the marking box 4. A clamping plate 32 is slidably arranged inside the marking box 4 on the placement plate. Rubber pads are fixedly embedded on one side of both clamping plates 32. The clamping plates 32 are brought into contact with the workpiece by sliding, and the workpiece is clamped. The rubber pads can increase the friction at the contact point between the clamping plates 32 and the workpiece to ensure stable clamping.

[0024] The inner wall of the marking box 4 is fixed with a telescopic rod 29 located on the lower side of the placement plate. The drive end of the telescopic rod 29 is fixed with a push plate 30 arranged in a "∩" shape. The lower side wall of each clamping plate 32 is fixed with a circular plate 33 by a fixing rod 34. The inner wall of the push plate 30 is provided with an inclined surface 31 that contacts the outer wall of the circular plate 33. A sliding groove 35 is provided at the connection between the placement plate and the fixing rod 34. The marking box 4 is pulled out, the workpiece is placed on the placement plate, and the telescopic rod 29 is activated. The drive end of the telescopic rod 29 reaches the push plate 30 and moves forward. The inclined surface 31 squeezes the circular plate 33 to move towards the center (the distance between the inclined surfaces 31 gradually decreases from front to back, so the circular plate 33 will be continuously squeezed towards the center when the push plate 30 moves forward). This causes the clamping plate 32 to move towards the center and contact the outer wall of the workpiece, thus completing the clamping of the workpiece.

[0025] After the workpiece is clamped, push the marking box 4 inward to move it into the machine body 1, and then the closed marking workpiece can be carried out.

[0026] The gas purification device includes a purification box 8 fixed to the outer wall of the body 1 by a connecting plate 2. A storage tank 9 containing activated carbon is fixed inside the purification box 8. A purification pipe 10 is connected to the lower side wall of the storage tank 9. An exhaust pipe 12 is connected between the purification pipe 10 and the body 1. An exhaust fan 11 is installed on the exhaust pipe 12. An outlet pipe 26 is also connected to the outer wall of the purification pipe 10. The purification pipe 10 is provided with a rotating column 27 for intermittently discharging activated carbon. A discharge port 28 is provided through the rotating column 27. The gas generated during the marking process is led out into the purification pipe 10 by the exhaust fan 11. The activated carbon in the purification pipe 10 adsorbs the odor in the gas. After the gas is adsorbed, the rotation of the rotating column 27 makes the discharge port 28 vertical. At this time, the activated carbon that has adsorbed the odor is discharged along the discharge port 28. The rotating column 27 is rotated again to make the discharge port 28 contact the inner wall of the purification pipe 10, thereby sealing the discharge port 28 and stopping the discharge of activated carbon.

[0027] A connecting groove 13 is fixed inside the purification box 8. A sliding plate 14 is slidably installed inside the connecting groove 13. A motor is fixed to the inner wall of the connecting groove 13. A cam 16 is fixed to the drive end of the motor. A connecting rod 15 is rotatably connected between the front side wall of the end of the cam 16 and the upper side wall of the sliding plate 14. A vertical rod 22 is fixed to the lower side wall of the sliding plate 14. A lever 21 is rotatably connected to the lower end of the vertical rod 22 via a torsion spring shaft. A pawl 23 is fixed to the end of the lever 21. A ratchet 20 is rotatably installed inside the purification box 8. The end of the pawl 23 contacts the outer wall of the ratchet 20. A rotating rod is fixed to the outer wall of the rotating column 27. Pulleys 24 are fixed to the outer walls of both the rotating rod and the ratchet 20. A belt 25 is fitted between the two pulleys 24. A bearing is fixedly embedded at the connection between the purification pipe 10 and the rotating rod. The rotating rod passes through the bearing and is fixedly connected to the inner ring of the bearing. The motor drives the cam 16 to rotate. The end of the cam 16 drives the upper end of the connecting rod 15 to perform a circular motion. The lower end of lever 15 reciprocates up and down, causing slide plate 14 to move up and down. When slide plate 14 moves upward, pawl 23 contacts the outer wall of ratchet 20 and connects, preventing ratchet 20 from rotating. When slide plate 14 moves downward, pawl 23 gets stuck between two ratchet teeth on ratchet 20, thus pushing ratchet 20 to rotate downward. At this time, belt 25 drives rotating column 27 to rotate, connecting discharge port 28 to purification pipe 10. Activated carbon that has adsorbed odors and harmful components is discharged from the lower end of purification pipe 10. When pawl 23 pushes ratchet 20 to rotate again, discharge port 28 contacts the inner wall of purification pipe 10, stopping the discharge of activated carbon. Furthermore, the continuous rotation of cam 16 enables intermittent discharge of activated carbon from the lower end of purification pipe 10, ensuring that activated carbon adsorbs odors and harmful components before being discharged. This avoids the problem of odors and harmful components escaping due to weakened adsorption capacity caused by continuous operation of activated carbon and failure to replace it in time.

[0028] A guide rod 17 is slidably inserted into the upper side wall of the purification box 8. A horizontal plate 18 is fixed at the upper end of the guide rod 17, which is located on the upper side wall of the cam 16 and in contact with the outer wall of the cam 16. A pressing rod 19 is fixed at the end of the horizontal plate 18. A switch 36 located below the end of the pressing rod 19 is fixed on the upper side wall of the connecting plate 2. A solenoid valve connected to the switch 36 is installed on the outer wall of the exhaust pipe 12. When the cam 16 drives the connecting rod 15 to move downward, the ratchet 20 is rotated by the pawl 23. Under the action of gravity, the horizontal plate 18 moves downward, the pressing rod 19 presses the switch 36, and the solenoid valve is energized and closed, ensuring that gases containing odors and harmful components will not be discharged from the lower end of the exhaust pipe 12 when the activated carbon is discharged.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
