Description

Technical Field

[0001] This utility model belongs to the field of marking machine technology, specifically relating to a dual-head laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam 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, thus engraving exquisite patterns, trademarks, and text. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are mainly used in applications requiring higher precision and finer details.

[0003] The laser marking machine used in general has its marking head installed at the top of the equipment. It can only mark one side of the material. If it is necessary to mark both sides of the material, the material needs to be flipped after marking one side, and then the other side needs to be marked. This marking method is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a dual-head laser marking machine, in which two laser marking heads mark two surfaces of a nameplate respectively, thereby improving marking efficiency and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-head laser marking machine, comprising a base and a turntable, the turntable being rotatably connected to the top of the base, the side wall of the turntable being provided with mounting structures equidistantly distributed around the axis of the turntable, a mounting frame being provided at the center of the top of the base, an L-shaped column being provided on the side wall of the base, a laser marking head being provided at one end of the mounting frame and one end of the L-shaped column, the two laser marking heads being arranged correspondingly above and below, a detection component being provided on the side wall of the base, an electric telescopic rod for pushing the mounting structures being provided at the top of the base, and a controller being provided on the side wall of the base.

[0006] Furthermore, a ring is fixedly connected to the middle of the bottom end of the turntable. The ring is rotatably connected to the top of the base through a bearing. A first gear is fixedly sleeved on the bottom of the ring. A servo motor is installed inside the base. A second gear is fixedly sleeved on the output shaft of the servo motor. The second gear meshes with the first gear.

[0007] Furthermore, the mounting structure includes a mounting groove provided on the side wall of the turntable, a discharge assembly is slidably connected inside the mounting groove, and support strips are fixedly connected to both sides of the inner wall of the mounting groove.

[0008] Furthermore, the discharge assembly includes a baffle and a pusher plate. Both sides of the baffle are fixedly connected to cylinders, and the side walls of the two cylinders are respectively fixedly connected to both sides of the pusher plate. The cylinders are slidably connected to both sides of the mounting groove.

[0009] Furthermore, a spring is fixedly connected inside the cylinder, and one end of the spring is fixedly connected to one end of the mounting groove.

[0010] Furthermore, the detection component includes a detection component fixedly connected to the side wall of the base, a mounting rod fixedly connected to the top of the detection component, an infrared emitting end fixedly installed at one end of the mounting rod, and an infrared receiving end provided at the top of the tray, with the infrared emitting end and the infrared receiving end being correspondingly arranged.

[0011] Furthermore, the infrared receiver is electrically connected to the controller, and both the electric telescopic rod and the servo motor are electrically connected to an external power supply through the controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: when the nameplate rotates between the two laser marking heads, the turntable stops rotating, and the two laser marking heads mark the two surfaces of the nameplate respectively, improving the marking efficiency.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1-4 As shown, a dual-head laser marking machine includes a base 1 and a turntable 2. The turntable 2 is rotatably connected to the top of the base 1. The side wall of the turntable 2 is provided with mounting structures 3 equidistantly distributed around the axis of the turntable 2. The middle of the top of the base 1 is provided with a mounting bracket 4. The side wall of the base 1 is provided with an L-shaped column 5. One end of the mounting bracket 4 and one end of the L-shaped column 5 are provided with laser marking heads 6. The two laser marking heads 6 are arranged vertically and vertically. The side wall of the base 1 is provided with a detection component 7. The top of the base 1 is provided with an electric telescopic rod 8 for pushing the mounting structure 3. The side wall of the base 1 is provided with a controller 9.

[0021] According to the above structure, during use, the nameplate to be marked is placed inside the mounting structure 3, and then the mounting structure 3 is rotated by the turntable 2. When the nameplate rotates between the two laser marking heads 6, the turntable 2 stops rotating, and the two laser marking heads 6 mark the two surfaces of the nameplate respectively. After the marking is completed, the turntable 2 drives the nameplate to rotate again. When the nameplate rotates to correspond to one end of the electric telescopic rod 8, the electric telescopic rod 8 extends to push out the mounting structure 3, thereby pushing out the nameplate. The detection component 7 is used to detect whether there is a nameplate inside the mounting structure 3, so as to prevent the mounting structure 3 without a nameplate from rotating between the two laser marking heads 6 and causing equipment damage.

[0022] like Figure 4 As shown, a ring 21 is fixedly connected to the middle of the bottom end of the turntable 2. The ring 21 is rotatably connected to the top of the base 1 through a bearing. A first gear 22 is fixedly sleeved on the bottom of the ring 21. A servo motor 23 is installed inside the base 1. A second gear 24 is fixedly sleeved on the output shaft of the servo motor 23. The second gear 24 meshes with the first gear 22.

[0023] According to the above structure, in use, the servo motor 23 drives the second gear 24 to rotate, which is then transmitted through the first gear 22, thereby driving the ring 21 and the turntable 2 to rotate.

[0024] like Figure 2As shown, the installation structure 3 includes an installation groove 31 set on the side wall of the turntable 2. A discharge assembly 32 is slidably connected inside the installation groove 31. Support bars 33 are fixedly connected to both sides of the inner wall of the installation groove 31. The discharge assembly 32 includes a baffle 321 and a push plate 322. A cylinder 323 is fixedly connected to both sides of the baffle 321. The side walls of the two cylinders 323 are fixedly connected to both sides of the push plate 322 respectively. The cylinders 323 are slidably connected to both sides of the installation groove 31. A spring 324 is fixedly connected inside the cylinder 323. One end of the spring 324 is fixedly connected to one end of the installation groove 31.

[0025] According to the above structure, when the nameplate is placed, the discharge assembly 32 retracts into the mounting groove 31. The nameplate is placed inside the mounting groove 31 and supported by two support bars 33. When the nameplate needs to be removed, the push plate 322 is pushed outward by extending the electric telescopic rod 8. At this time, the cylinder 323 and the baffle 321 move outward together with the push plate 322, and the spring 324 is stretched. While the push plate 322 moves outward, it pushes the nameplate to slide outward. When the nameplate is separated from the support bar 33, it will automatically fall and be retrieved. After the nameplate falls, the electric telescopic rod 8 retracts, and the push plate 322 retracts inward under the elastic force of the spring 324.

[0026] like Figure 4 As shown, the detection component 7 includes a detection component 7 fixedly connected to the side wall of the base 1. A mounting rod 72 is fixedly connected to the top of the detection component 7. An infrared emitting end 73 is fixedly installed at one end of the mounting rod 72. An infrared receiving end 74 is provided at the top of the support plate 71. The infrared emitting end 73 and the infrared receiving end 74 are correspondingly arranged. The infrared receiving end 74 is electrically connected to the controller 9. The electric telescopic rod 8 and the servo motor 23 are both electrically connected to an external power supply through the controller 9.

[0027] According to the above structure, nameplates are placed inside the mounting slot 31 in sequence during use. As the turntable 2 rotates, the nameplates move closer to the laser marking head 6. When the mounting slot 31 moves between the infrared emitting end 73 and the infrared receiving end 74, if there is no nameplate inside the mounting slot 31, the infrared receiving end 74 receives the infrared signal from the infrared emitting end 73. The infrared receiving end 74 sends the received signal to the controller 9, and the controller 9 controls the servo motor 23 to stop rotating, so as to prevent the mounting slot 31 without a nameplate from rotating between the two laser marking heads 6.

[0028] The working principle of this utility model is as follows: In use, the servo motor 23 drives the second gear 24 to rotate, which in turn drives the ring 21 and the turntable 2 to rotate via the first gear 22. When placing the nameplate, the discharge assembly 32 retracts entirely into the mounting groove 31, and the nameplate is placed inside the mounting groove 31 and supported by two support bars 33. When it is necessary to remove the nameplate, the extension electric telescopic rod 8 pushes the push plate 322 outward. At this time, the cylinder 323 and the baffle 321 move outward together with the push plate 322, and the spring 324 is stretched. As the push plate 322 moves outward, it pushes the nameplate to slide outward. When the nameplate is separated from the support bar 33... The nameplate can be automatically dropped for recycling. After the nameplate falls off, the retractable electric telescopic rod 8 retracts inward under the elastic force of the spring 324, and the push plate 322 retracts inward. During use, nameplates are placed into the mounting slot 31 in sequence. As the turntable 2 rotates, the nameplates move closer to the laser marking head 6. When the mounting slot 31 moves between the infrared emitting end 73 and the infrared receiving end 74, if there is no nameplate inside the mounting slot 31, the infrared receiving end 74 receives the infrared signal from the infrared emitting end 73. The infrared receiving end 74 sends the received signal to the controller 9. The controller 9 controls the servo motor 23 to stop rotating to prevent the mounting slot 31 without a nameplate from rotating between the two laser marking heads 6.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
