Description

Technical Field

[0001] The utility model relates to the technical field of oil removal, in particular to a laser oil removal device. Background Art

[0002] Copper-aluminum composite plate is a new type of material that is made by welding copper and aluminum plates together through cold rolling, hot rolling, explosive bonding, explosive rolling, etc., and cannot be separated. However, when copper and aluminum are composited, there is an occasional oil stain problem on the surface of the copper strip, which affects the strength of the copper strip and the aluminum liquid.

[0003] In order to better solve the problem of copper strip degreasing, degreasing is often carried out by scrubbing and scraping. Although the degreasing effect can be achieved, it consumes a lot of man-hours and affects the processing efficiency. It is now proposed to use laser degreasing method to remove oil stains from copper strips. However, after degreasing, some dust will adhere to the surface of the copper strip due to the effect of laser cleaning. The residual dust will still affect the composite strength of the copper strip and the aluminum liquid. Utility Model Content

[0004] In response to the shortcomings of existing oil removal equipment, the utility model provides a laser oil removal equipment, which has the advantages of removing oil stains and cleaning dust on the surface of copper strips by laser, improving the strength of copper-aluminum composite, softening oil stains by heating, and improving the oil removal effect, solving technical problems such as cleaning oil stains on copper strips and cleaning dust on the surface of copper strips.

[0005] The utility model provides the following technical solution: a laser degreasing device, comprising a base, and further comprising:

[0006] The mounting plate is fixedly mounted on the right side of the top surface of the base, and baffles are fixedly mounted on the front and rear side surfaces of the mounting plate. The uncoiler wheel is rotatably mounted on the left side of the top surface of the mounting plate through a support rod, and the top surface of the mounting plate is located on the right side of the uncoiler wheel and is rotatably mounted on a follower wheel through a support rod;

[0007] The casting roller is rotatably mounted on the top surface of the base and located on the lower side of the follower wheel. The top surface of the base is located on the left side of the casting roller and is rotatably mounted with a coiler wheel through a support rod. A through groove is provided on the top surface of the mounting plate. A copper strip is wrapped around the uncoiler wheel. The copper strip is sequentially wrapped around the outer surface of the follower wheel, passes through the through groove, and is wrapped around the outer surfaces of the casting roller and the coiler wheel.

[0008] Preferably, the mounting plate includes:

[0009] The laser device is fixedly connected to the right side wall of the mounting plate and is located on the upper side of the casting roller.

[0010] Preferably, the mounting plate further includes:

[0011] A fixing block, fixedly connected to the right side wall of the mounting plate and located at the lower side of the laser device;

[0012] The movable cavity is arranged inside the fixed block.

[0013] Preferably, the interior of the active cavity includes:

[0014] A movable plate, slidably connected to the interior of the movable cavity;

[0015] A connecting plate fixedly connected to the middle portion of the side of the movable plate facing the casting roll;

[0016] A spring is fixedly connected to the middle portion of the side surface of the movable plate facing the mounting plate, and one end of the spring away from the movable plate is fixedly connected to the side wall of the movable cavity.

[0017] Preferably, the connecting plate includes:

[0018] A cleaning plate is fixedly connected to one end of the connecting plate facing the casting roll, and the end surface of the cleaning plate is in contact with the copper strip.

[0019] Preferably, the through groove includes:

[0020] A mounting block fixedly connected to the side wall of the through slot;

[0021] a heating rod, fixedly connected to the mounting block;

[0022] A switch is fixedly connected to the top surface of the mounting plate and is located at the side of the through slot, and the switch is used to control the opening and closing of the heating rod.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By designing laser equipment, during the process of copper strip and aluminum liquid compounding, the laser equipment is set up between the uncoiler wheel and the follower wheel. Since the uncoiler wheel and the coiler wheel form a tension closed-loop system, the angle between the follower wheel and the casting roll is unchanged. Therefore, setting the laser equipment between the uncoiler wheel and the follower wheel can shorten the distance between the copper strip and the aluminum liquid. Then, by utilizing the effect of tension, since the copper strip composite surface is coated with passivation liquid and rolling oil, the surface of the copper strip is cleaned by the action of laser without damaging the surface quality of the copper strip, thereby increasing the peeling strength during copper-aluminum compounding.

[0025] 2. By designing the fixed block, movable cavity, movable plate, connecting plate and cleaning plate, the elastic potential energy of the spring is used to prompt the movable plate to drive the connecting plate and the cleaning plate to contact the outer surface of the copper strip. Since the copper strip has been degreased by the laser equipment at this time, the dust generated after laser degreasing will be removed by the cleaning plate, making the outer surface of the copper strip cleaner and further improving the peeling strength of the copper-aluminum composite.

[0026] 3. By designing the mounting block, heating rod and switch light, during the process of compounding the copper strip and the aluminum liquid, turn on the switch to make the heating rod work and generate heat. At this time, the heating rod is used to heat the oil stains on the surface of the copper strip to soften the oil stains, thereby improving the effect of laser degreasing of the copper strip and avoiding some thicker oil stains that are difficult to be cleaned by the laser equipment. In addition, the preheating of the copper strip by the heating rod allows the copper strip and the aluminum liquid to be better compounded, thereby improving the compounding effect.

A through groove 8 is opened on the top surface of the mounting plate 2, and a copper strip 9 is wrapped around the uncoiler wheel 4. The copper strip 9 is sequentially wound around the outer surface of the follower wheel 5, passes through the through groove 8, and is wound around the outer surfaces of the casting roller 6 and the coiler wheel 7.

[0038] See also Figure 1-Figure 5 A cleaning plate 27 is fixedly welded to one end of the connecting plate 25 facing the casting roller 6. The end face of the cleaning plate 27 is in contact with the copper strip 9. The spring 26 pushes the movable plate 24 so that the cleaning plate 27 can always be in contact with the copper strip 9.

[0039] See also Figure 1-Figure 5 A mounting block 81 is fixedly welded on the side wall of the through groove 8, and a heating rod 82 is fixedly mounted on the mounting block 81. A switch 83 is fixedly mounted on the top surface of the mounting plate 2 at the side of the through groove 8. The switch 83 is used to control the opening and closing of the heating rod 82. When the switch 83 is used to turn on the heating rod 82, the heating rod 82 will heat the oil stains on the copper strip 9, softening the thicker oil stains and facilitating cleaning. In addition, the heating of the copper strip 9 is conducive to the compounding of the copper strip 9 and the aluminum liquid.

[0040] Working principle: During the process of copper strip 9 and aluminum liquid compounding, a laser device 21 is set up between the uncoiler wheel 4 and the follower wheel 5. Since the uncoiler wheel 4 and the coiler wheel 7 form a tension closed loop system, the angle between the follower wheel 5 and the casting roller 6 is unchanged. Therefore, the laser device 21 is set up between the uncoiler wheel 4 and the follower wheel 5 to shorten the distance between the copper strip 9 and the aluminum liquid. Then, by utilizing the effect of the tension, since the composite surface of the copper strip 9 is coated with passivation liquid and rolling oil, the surface of the copper strip 9 is cleaned by the effect of the laser without damaging the surface quality of the copper strip 9, thereby increasing the peeling strength during copper-aluminum compounding. At the same time, the elastic potential energy of the spring 26 is used to prompt the movable plate 24 to drive the connecting plate 25 and the cleaning plate 27 to contact each other. On the outer surface of the copper strip 9, since the copper strip 9 has been degreased by the laser equipment 21 at this time, the dust generated after the laser degreasing will be removed by the cleaning plate 27, making the outer surface of the copper strip 9 cleaner, further improving the peeling strength during copper-aluminum composite. Secondly, during the composite process of the copper strip 9 and the aluminum liquid, the switch is turned on to make the heating rod 82 work and generate heat. At this time, the heating rod 82 is used to heat the oil stains on the surface of the copper strip 9 to soften the oil stains, thereby improving the effect of laser degreasing of the copper strip 9 and avoiding some thicker oil stains that are difficult to be cleaned by the laser equipment 21. In addition, the preheating of the copper strip 9 by the heating rod 82 allows the copper strip 9 and the aluminum liquid to be better composited, thereby improving the composite effect.
