Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot production, specifically to an aluminum ingot production marking device. Background Technology

[0002] Aluminum ingot production marking devices are specialized equipment used to automatically print marking information on the surface of aluminum ingots. They are usually integrated at the end of the casting production line. Through mechanical positioning, laser or inkjet coding technology, they clearly engrave or spray data such as alloy grade, batch number, and production date on the surface of aluminum ingots to ensure product traceability. The device consists of a conveying mechanism, coding system, and control system. It is characterized by high temperature resistance and high precision, meets industry standards, and facilitates subsequent warehousing and distribution management. It is a key link in the quality control of aluminum ingot production. To avoid wear and tear from the marking, marking is usually performed on both sides of the aluminum ingot.

[0003] The existing aluminum ingot production marking equipment has certain limitations in use. The main problem is that it cannot lift and reverse the aluminum ingots on the conveyor rollers. Since the aluminum ingots can only move in one direction during the conveying process, if marking is required at different positions, two additional laser marking machines must be installed, or the aluminum ingots must be removed from the production line, manually adjusted in direction, and then put back into the conveying system for secondary marking. This operation method not only increases the equipment investment cost, but also causes production process interruption, prolongs processing time, and reduces overall production efficiency, which is not conducive to the needs of modern and efficient aluminum ingot production.

[0004] In summary, to improve the automation level and processing efficiency of aluminum ingot production lines, it is necessary to solve the problem that existing marking devices cannot automatically lift and reverse aluminum ingots on conveyor rollers, so that aluminum ingots can be marked on multiple sides in a single transmission process, thereby reducing repeated equipment investment, avoiding secondary handling, and improving production smoothness and economy. Utility Model Content

[0005] The purpose of this invention is to provide a marking device for aluminum ingot production.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Refer to the instruction manual appendix Figures 1 to 6 A marking device for aluminum ingot production includes an equipment cabinet 1, a conveyor roller 2 mounted on the equipment cabinet 1, a base plate 6 installed inside the equipment cabinet 1, a first support 7 fixed on the base plate 6, a slider 8 slidably connected to the first support 7, a locking assembly provided on the front side of the slider 8, a sliding rod provided on the locking assembly, a limit frame 10 provided on the slider 8, a drive motor 11 fixed on the base plate 6, a rotating shaft 12 mounted on the output end of the drive motor 11, and a connector 13 fixed to the end of the rotating shaft 12. A protrusion 14 is fixed on the connector 13, which is adapted to the limiting frame 10. A second bracket 15 is fixed on the base plate 6. A turntable 16 is rotatably connected between the first bracket 7 and the second bracket 15. A limiting strip 18 is provided on the outer side of the slide rod. Two intersecting guide grooves 17 are opened on the outer side of the turntable 16. A fixed platform 19 is fixed on the base plate 6. A drive shaft 20 is installed on the fixed platform 19. Two push rods 21 are installed on the outer side of the drive shaft 20. An anti-slip plate 26 is installed on the top of the slide rod.

[0025] It should be noted that the drive motor 11 drives the connector 13 and the protrusion 14 to rotate through the rotating shaft 12. The protrusion 14 is embedded in the limiting frame 10, and its rotational motion is converted into the reciprocating linear motion of the slider 8. The movement of the slider 8 drives the slide rod and the anti-slip plate 26 on its top (used to carry aluminum ingots) to move up and down through the locking assembly. This causes the anti-slip plate 26 to be pushed out from the gap of the conveying roller 2 and lift the aluminum ingot. At the same time, the limiting strip 18 on the outside of the slide rod restricts its direction of movement. When the transmission shaft 20 rotates, the end of the push rod 21 on it enters the corresponding guide groove 17, thereby driving the turntable 16 to rotate around its axis, and finally realizing the lifting and reversing of the aluminum ingot on the anti-slip plate 26.

[0026] Refer to the instruction manual appendix Figures 1 to 6A lifting assembly is provided on the outer side of the conveyor roller 2. A laser marking machine 4 is installed on the lifting assembly. A suction assembly for absorbing exhaust gas is provided on the outer side of the laser marking machine 4. A second synchronous wheel 23 is fixed on the outer side of the rotating shaft 12. A first synchronous wheel 22 is fixed on the outer side of the transmission shaft 20. A synchronous belt 24 is sleeved on the outer side of the first synchronous wheel 22 and the second synchronous wheel 23. A limit assembly is provided on the outer side of the transmission shaft 20. The limit assembly is used to limit the rotation of the turntable 16. A cleaning mechanism for cleaning the surface of aluminum ingots is provided on the conveyor roller 2.

[0027] It should be noted that the lifting component is used to adjust the height of the laser marking machine 4 to adapt to the position or different specifications of the aluminum ingot. The suction component is responsible for collecting the smoke and exhaust gas generated by laser marking to keep the working environment clean. The synchronous belt 24 connects the first synchronous pulley 22 and the second synchronous pulley 23 to ensure that the transmission shaft 20 and the rotating shaft 12 of the drive motor 11 rotate synchronously, so that the movement of the push rod 21 and the movement of the slide rod are coordinated. The limit component limits the position of the turntable 16 after the reversing action is completed to ensure the stable lifting and lowering of the slide rod. The cleaning mechanism automatically cleans the surface of the aluminum ingot before it enters the marking station to remove impurities and ensure the marking quality.

[0028] Refer to the instruction manual appendix Figures 2 to 5 The locking assembly includes a slot 91 on the outside of the slide bar and a locking rod 92 fixed on the slider 8. The locking rod 92 is slidably connected to the slot 91. The limiting assembly includes a fixing rod 251 fixed on the drive shaft 20, an arc plate 252 fixed at the end of the fixing rod 251, and a slot 253 on the turntable 16. The arc plate 252 is adapted to the slot 253.

[0029] It should be noted that by sliding the lever 92 in the slot 91 of the slide bar, the linear motion of the slider 8 is reliably transmitted to the slide bar without hindering the rotation of the slide bar. The arc plate 252 fixed on the transmission shaft 20 cooperates with the slot 253 on the turntable 16. In the non-reversing state, it is locked into the slot 253, effectively preventing the turntable 16 from rotating and ensuring the positional stability and accuracy of the aluminum ingot during the marking or transmission process.

[0030] Refer to the instruction manual appendix Figure 1 The lifting assembly includes a screw jack 31 fixed to the outside of the conveyor roller 2 and a fixing plate 32 fixed to the outside of the screw jack 31. The lifting end of the screw jack 31 is fixedly connected to the laser marking machine 4. The screw jack 31 is fixedly connected to the conveyor roller 2 through the fixing plate 32. The screw jack 31 is used to drive the laser marking machine 4 to lift.

[0031] It should be noted that the screw jack 31 can drive the laser marking machine 4 to perform vertical lifting movements, enabling it to precisely adjust the focusing position according to the actual height of the aluminum ingot or process requirements, ensuring the clarity and consistency of the marking.

[0032] Refer to the instruction manual appendix Figure 1 The suction assembly includes a positioning seat 51 fixed to the outside of the laser marking machine 4, an air tube 52 attached to the inside of the positioning seat 51, and a diffuser shroud 53 fixed to the bottom of the air tube 52. The air tube 52 is positioned by the positioning seat 51 and is connected to an external suction air pump.

[0033] It should be noted that an external air pump is used for suction, the diffuser 53 expands the suction range, and the air pipe 52 discharges the exhaust gas and centrally treats it, ensuring clean air in the operating area and meeting environmental protection requirements.

[0034] Refer to the instruction manual appendix Figure 1 and Figure 6 The cleaning mechanism includes a wiping component and an elastic component. The wiping component is used to clean the surface of the aluminum ingot, and the elastic component is used to apply an elastic preload to keep the wiping component in contact with the aluminum ingot.

[0035] It should be noted that the wiping component is responsible for performing the physical wiping action to remove dirt, while the elastic component ensures that the wiping component can adapt to the thickness of the aluminum ingot, always maintaining effective and uniform contact pressure, thus improving the cleaning effect.

[0036] Refer to the instruction manual appendix Figure 1 and Figure 6 The wiping assembly includes two supports 271 fixed on the conveyor roller 2, a slide block 272 slidably connected inside the support 271, a cleaning roller 273 rotatably connected between the two slide blocks 272, and a servo motor 274 fixed on the slide block 272. The output end of the servo motor 274 is fixedly connected to the cleaning roller 273, and the servo motor 274 is used to drive the cleaning roller 273 to rotate.

[0037] It should be noted that the servo motor 274 drives the cleaning roller 273 to rotate at high speed, effectively removing impurities such as dust, oil, or oxide layer from the surface of the aluminum ingot using friction, thus providing a clean surface base for subsequent laser marking.

[0038] Refer to the instruction manual appendix Figure 6 The elastic component includes a guide rod 275 fixed inside the support 271 and a spring 276 sleeved on the outside of the guide rod 275. The slide 272 is slidably connected to the guide rod 275, and the two ends of the spring 276 are fixedly connected to the slide 272 and the support 271, respectively.

[0039] It should be noted that the spring 276 generates a preload through its compression deformation, which enables the cleaning roller 273 to fit tightly against the surface of the aluminum ingot, ensuring stable and effective cleaning contact even if the size of the aluminum ingot changes slightly.

[0040] Working principle: The aluminum ingot is conveyed to the marking station by the conveyor roller 2. First, the servo motor 274 drives the cleaning roller 273 to rotate. Under the elastic pressure applied by the spring 276 through the guide rod 275, the cleaning roller 273 closely adheres to the surface of the aluminum ingot for cleaning. After marking on one side is completed, the drive motor 11 starts, driving the rotating shaft 12 and its end connector 13 and protrusion 14 to rotate. The protrusion 14 is embedded in the limiting frame 10 of the slider 8, converting the rotational motion into the linear reciprocating motion of the slider 8 along the first support 7. The slider 8 cooperates with the slot 91 on the outside of the slide bar through the locking rod 92 on it, driving the slide bar and the anti-slip plate 26 on the top to lift the aluminum ingot from the gap of the conveyor roller 2. Meanwhile, the rotating shaft 12 drives the transmission shaft 20 to rotate synchronously through the second synchronous wheel 23, the synchronous belt 24 and the first synchronous wheel 22. The push rod 21 on the transmission shaft 20 is inserted into the guide groove 17 of the turntable 16, driving the turntable 16 to rotate around the shaft, thereby driving the slide rod fixed on it and the aluminum ingot on the anti-slip plate 26 to complete the reversal. After the reversal is completed, the arc plate 252 is re-engaged into the slot 253 to lock the turntable 16. Then, the screw jack 31 adjusts the laser marking machine 4 to a suitable height for marking. The exhaust gas generated by marking is sucked out by the air pipe 52 fixed by the positioning seat 51 and the diffuser 53. Finally, the anti-slip plate 26 descends and the aluminum ingot falls back to the conveyor roller 2 and is sent out.
