DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] Reference Figure 1-5 A closed modular fiber laser marking machine includes a body 1 and a fiber laser 7 located in 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 a marking box 4. The Z-axis guide rail 5 and the X-axis guide rail 6 are both composed of guide rails and sliders arranged on the guide rails. The end of the X-axis guide rail 6 is fixed to the outer wall of the slider on the Z-axis guide rail 5. The fiber laser 7 is fixed to the lower side wall of the slider on the X-axis guide rail 6. The fiber laser 7 is driven by the Z-axis guide rail 5 and the X-axis guide rail 6 to move on the Z-axis and X-axis to achieve multi-directional laser marking.

[0017] The outer wall of the body 1 is connected to a gas purification device, and a slot 3 is opened on the outer wall of the body 1. A marking box 4 is slidably inserted in the slot 3. A clamping mechanism is provided in the marking box 4. The clamping mechanism includes a placement plate fixed inside the marking box 4. A clamp 32 located on the placement plate is slidably provided in the marking box 4. Rubber pads are fixedly embedded on one side of the two clamps 32. The clamps 32 are brought into contact with the workpiece through the sliding of the clamps 32 to complete the clamping of the workpiece. The provided rubber pads can increase the friction at the contact between the clamps 32 and the workpiece to ensure the stability of the clamping.

[0018] The inner wall of the marking box 4 is fixed with a telescopic rod 29 located at the lower side of the placement plate, and the driving 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 through a fixing rod 34. The inner wall of the push plate 30 is provided with an inclined surface 31 in contact with the outer wall of the circular plate 33, and a slide groove 35 is provided at the connection between the placement plate and the fixing rod 34. The marking box 4 is pulled out, and the workpiece is placed on the placement plate. The telescopic rod 29 is started, and the driving end of the telescopic rod 29 reaches the push plate 30 and moves forward, and squeezes the circular plate 33 to move toward the middle through the inclined surface 31 (the distance between the inclined surfaces 31 from front to back gradually decreases, so when the push plate 30 moves forward, it will continuously squeeze the circular plate 33 to move toward the middle), driving the clamping plate 32 to move toward the middle and contact the outer wall of the workpiece, thereby completing the clamping of the workpiece.

[0019] After the workpiece is clamped, the marking box 4 is pushed inward to move it into the machine body 1, and now the closed marking work of the workpiece can be carried out.

[0020] The gas purification device includes a purification box 8 fixed to the outer wall of the body 1 through a connecting plate 2, a storage tank 9 storing activated carbon is fixed in 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, and 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 the activated carbon, and a discharge port 28 is provided on the rotating column 27. The gas generated during the marking process is led out to the purification pipe 10 through the exhaust fan 11, and the activated carbon in the purification pipe 10 adsorbs the odor in the gas. After the gas is adsorbed, the discharge port 28 is vertically positioned by rotating the rotating column 27. At this time, the activated carbon that has adsorbed the odor is discharged along the discharge port 28, and the rotating column 27 is continuously rotated to make the discharge port 28 contact with the inner wall of the purification pipe 10, and the discharge port 28 is closed to stop the discharge of the activated carbon.

[0021] A connecting groove 13 is fixed in the purification box 8, and a slide plate 14 is slidably arranged in the connecting groove 13. A motor is fixed to the inner wall of the connecting groove 13, and a cam 16 is fixed to the driving 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 slide plate 14. A vertical rod 22 is fixed to the lower side wall of the slide plate 14, and a lever 21 is rotatably connected to the lower end of the vertical rod 22 through a torsion spring rotating shaft. A pawl 23 is fixed to the end of the lever 21. A ratchet 20 is rotatably installed in the purification box 8, and 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, and a pulley 24 is fixed to the outer wall of the rotating rod and the ratchet 20. A belt 25 is commonly sleeved between the two pulleys 24. A bearing is fixedly embedded at the connection between the purification tube 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, and the end of the cam 16 drives the upper end of the connecting rod 15 to make a circular motion. The lower end of the rod 15 makes a reciprocating motion up and down, driving the slide plate 14 to move up and down. When the slide plate 14 moves up, the pawl 23 is connected to the outer wall of the ratchet 20 when in contact, and will not push the ratchet 20 to rotate. When the slide plate 14 moves down, the pawl 23 will be stuck between the two ratchet teeth on the ratchet 20, thereby pushing the ratchet 20 to rotate downward. At this time, the belt 25 drives the rotating column 27 to rotate, so that the discharge port 28 is connected with the purification pipe 10. At this time, the activated carbon that adsorbs odor and harmful components is discharged from the lower end of the purification pipe 10. When the pawl 23 pushes the ratchet 20 to rotate next time, the discharge port 28 contacts the inner wall of the purification pipe 10 to stop the discharge of the activated carbon, and then the intermittent discharge of the activated carbon at the lower end of the purification pipe 10 can be achieved through the continuous rotation of the cam 16, and the activated carbon is discharged after it adsorbs the odor and harmful components, avoiding the problem of odor and harmful components escaping due to the weakening of the adsorption force of the activated carbon due to continuous work and the inability to replace it in time.

[0022] A guide rod 17 is slidably inserted into the upper side wall of the purification box 8, and a horizontal plate 18 located on the upper side wall of the cam 16 and in contact with the outer wall of the cam 16 is fixed to the upper end of the guide rod 17. A pressing rod 19 is fixed to the end of the horizontal plate 18, and a switch 36 located on the lower side of the end of the pressing rod 19 is fixed to 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 and the ratchet 20 is rotated by the pawl 23, the horizontal plate 18 moves downward under the action of gravity, the pressing rod 19 presses the switch 36, and the solenoid valve is energized and closed to ensure that the gas containing odor and harmful components will not be discharged from the lower end of the exhaust pipe 12 when the activated carbon is discharged.

[0023] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
