Description

Technical Field

[0001] The invention relates to the technical field of laser processing, and in particular to a surface coating laser cleaning device applied to waste hard alloy. Background Art

[0002] Waste carbide plates contain valuable components such as tungsten, cobalt, and titanium. In order to reuse waste carbide plates, they need to be restored to a state close to the original material. Generally, staff will use lasers to process the surface coating. Laser cleaning is a non-contact cleaning method. By adjusting relevant parameters, the laser energy is mainly applied to the coating of the waste carbide plates, avoiding damage to the carbide substrate caused by physical friction and impact.

[0003] When laser cleaning waste carbide plates, it is necessary to use a clamp to limit and fix them to ensure that the laser can accurately irradiate the surface area that needs to be cleaned. When a traditional clamp is used to limit the waste carbide plates, the limiter in the clamp needs to contact the surface of the waste carbide plates to limit and fix the waste carbide. However, when the limiter contacts the surface of the carbide plates, the limiter will block its surface. After cleaning, the covered area will show obvious signs of uncleaning, affecting the uniformity and integrity of the overall cleaning effect and reducing the cleaning quality.

[0043] The principle and advantages of laser cleaning equipment for surface coating of scrap hard alloy:

[0044] Loading process:

[0045] First, the staff places the waste carbide plate on the top of the feeding rack 32. At this time, the electric slide rail at the bottom of the base 21 will drive the mounting rack 31 to move to the bottom of the ring rack 241. The telescopic unit inside the mounting rack 31 will drive the waste carbide plate to move to the bottom of the ring rack 241. Then, the driving member in the mounting seat will drive the gear 2453 to rotate. Since the gear 2453 and the gear ring 2452 are meshed with each other, the ring plate 2451 will rotate along the slide groove at the top of the ring rack 241. When the ring plate 2451 rotates a corresponding angle, the abutment plate 2454 inside it will rotate synchronously with the ring frame 241. It is worth mentioning that the middle position of the concave arc plate is the thinnest, and the thickness increases gradually toward both sides, and the middle position of the convex arc plate is the thickest, and the thickness decreases gradually toward both sides. In addition, magnetic parts are provided inside the concave arc plate and the convex arc plate, which can generate adsorption force between the abutment block 2455 to ensure that the abutment block 2455 can always fit with the curved surface of the abutment plate 2454.

[0046] The abutment block 2455 on the movable plate 2442 fits with the thinnest position in the middle of the inner concave arc plate, and the abutment block 2455 on the telescopic rod 2432 fits with the thickest position of the outer convex arc plate. At this time, the limit long plate 24422 is farthest from the waste carbide plate, and the limit short plate 24441 is closest to the waste carbide plate. As the ring plate 2451 rotates, the abutment block 2455 on the movable plate 2442 will gradually be squeezed by the inner concave arc plate, so that the movable plate 2442 will gradually approach the side wall of the waste carbide plate. Since the movable plate 2442 is connected to the square rod 2444 through the connecting plate 24442, when the movable plate 2442 is close to the square rod 2444 When approaching the waste carbide plate, the square rod 2444 will drive the limiting short plate 24441 to gradually move away from the waste carbide plate, and the movable plate 2442 will drive the limiting long plate 24422 to gradually approach the waste carbide plate. During the movement of the movable plate 2442, the counterweight block 24431 installed on the top of the clamping plate 2443 will, under the action of its own gravity, engage the clamping plate 2443 in the clamping slot 24421, and the plane position between the clamping plate 2443 and the clamping slot 24421 will fit together, thereby further limiting the movable plate 2442 to prevent the movable plate 2442 from loosening and affecting the limiting effect of the limiting long plate 24422 on the waste carbide plate.

[0047] It is worth noting that one side of the slot 24421 and the card plate 2443 is set as an inclined surface, and the other side is set as a plane. When engaged, the card plate 2443 will fit with the side wall of the slot 24421. When the movable plate 2442 drives the limiting long plate 24422 to move toward the waste carbide plate, due to the large inclination angle of the inclined surface (the inclination angle of the inclined surface is greater than 45 degrees), only a small force needs to be applied to push the movable plate 2442, and a large vertical component force will be generated on the inclined surface, making it easier for the card plate 2443 to escape from the slot 24421, reducing the difficulty of separation between the card plate 2443 and the slot 24421, and avoiding the problem of difficulty in separation due to excessive engagement.

[0048] At the same time, the telescopic unit will drive the waste carbide plate to move into the support frame 242. When the limiting long plate 24422 is in contact with the side wall of the waste carbide plate, the limiting short plate 24441 will move to the farthest distance from the waste carbide plate, thereby firmly fixing the two side walls of the waste carbide plate. In addition, the limiting long plate 24422 is connected to the movable plate 2442 by an elastic member. When the ring plate 2451 continues to rotate, the movable plate 2442 can further improve the limiting effect of the limiting long plate 24422 on the waste carbide plate by squeezing the elastic member.

[0049] At the same time, the abutment block 2455 on the telescopic rod 2432 will move along the arc surface of the convex arc plate to the thinnest position. At this time, the electromagnet and the magnetic part inside the telescopic rod 2432 are in a state of mutual adsorption, so that the telescopic rod 2432 is in a contracted state, and then the limit block 2433 is farthest from the waste carbide plate. Then, the electric slide rail and the telescopic unit reset the mounting frame 31 to prevent the limit assembly 24 from interfering with the rotation of the flip frame 23 when it rotates, thereby affecting the normal rotation of the flip frame 23.

[0050] Cleaning process:

[0051] When the waste carbide plate is firmly fixed by the limiting long plate 24422, the laser cleaning body 1 will move to the top of the waste carbide plate and start cleaning the surface of the waste carbide plate from the side of the waste carbide plate close to the limiting block 2433 until the upper surface of the waste carbide plate is cleaned. After the cleaning is completed, the external driving unit will drive the flip frame 23 to flip 180 degrees (during the flipping process, the limiting long plate 24422 is still in a limiting state with respect to the waste carbide plate). After the flipping is completed, the driving part will drive the gear 2453 to rotate in the opposite direction, so that the ring plate 2451 can rotate in the opposite direction synchronously. At this time, the abutment block 2455 on the movable plate 2442 will gradually move toward the thinnest position of the inward concave arc plate, and the limiting long plate 24422 will gradually separate from the waste carbide plate. At the same time, the square rod 2444, in cooperation with the connecting plate 24442, will drive the limiting short plate 24441 to gradually approach the waste carbide plate until the limiting short plate 24441 and the waste carbide plate complete the limiting.

[0052] It is worth noting that when the external driving unit drives the flip frame 23 to flip 180 degrees, the counterweight block 24431 will move the card plate 2443 downward until it is out of the card slot 24421. After the flipping is completed, the limiting long plate 24422 and the limiting short plate 24441 are switched. At this time, the limiting short plate 24441 limits the waste carbide plate, and the limiting long plate 24422 and the waste carbide plate are released from the limit. In addition, the limiting long plate 24422 and the limiting short plate 24441 are both set to L shape. When the limiting long plate 24422 limits the waste carbide plate, the horizontal plate of the limiting long plate 24422 will be aligned with the uncleaned lower surface of the waste carbide plate. The surfaces are fitted together. When the limiting short plate 24441 limits the waste carbide plate, the horizontal plate of the limiting short plate 24441 will fit with the cleaned upper surface of the waste carbide plate. At the same time, the limiting long plate 24422 and the vertical plate of the limiting short plate 24441 are both provided with inclined surfaces. The vertical plate is not completely fitted with the side wall of the waste carbide plate, and a certain space is left with the inclined surface to avoid the limiting long plate 24422 and the limiting short plate 24441 covering the surface of the waste carbide plate during the cleaning process, thereby affecting the cleaning effect. At the same time, the length of the two limiting short plates 24441 is the same as that of the limiting long plate 24422, which can ensure the stability of the waste carbide plate during the limiting process.

[0053] When switching the limit long plate 24422 and the limit short plate 24441, the abutment block 2455 on the telescopic rod 2432 will move along the arc surface of the convex arc plate to the thickest position of the convex arc plate. At this time, the telescopic rod 2432 will be squeezed by the convex arc plate, driving the limit block 2433 to approach the waste carbide plate by a certain distance until the end face of the limit block 2433 fits with the side wall of the waste carbide plate, and then the electromagnet inside the telescopic rod 2432 will change the direction of the current, so that the electromagnet and the magnetic part repel each other, and then the telescopic rod 2432 will be in an extended state, so that the limit block 2433 can fit with the waste carbide plate through the limit groove 2434, and the waste carbide plate can be supported when the limit long plate 24422 and the limit short plate 24441 are switched to avoid its position changing and affecting the limit and subsequent cleaning.

[0054] After the switching of the limiting long plate 24422 and the limiting short plate 24441 is completed, the turning frame 23 drives the limiting assembly 24 and the waste carbide plate to turn 180 degrees. At this time, the uncleaned surface of the waste carbide plate will face upward, and the laser cleaning body 1 can be used to clean the surface of the waste carbide plate. After the cleaning is completed, the staff can remove the waste carbide plate and repeat the operation to clean the waste carbide plates in batches.

[0055] The present invention adopts the flip frame 23 and the limit assembly 24, which has the following advantages:

[0056] Advantage 1: By controlling the rotation of the flip frame 23 through an external driving unit, the waste carbide plate can be automatically turned over. After the laser cleaning body 1 completes the laser cleaning of one side of the waste carbide plate, the flip frame 23 automatically flips 180 degrees to make the other side of the waste carbide plate face the laser cleaning body 1, thereby completing the laser cleaning of the waste carbide plate. In conjunction with the feeding part 3, automatic loading can be achieved, with a high degree of automation, without the need for a large amount of manual operation, which is beneficial to improving the laser cleaning efficiency of the waste carbide plate.

[0057] Advantage 2: The laser cleaning body 1 starts cleaning the waste carbide plate from the non-clamping surface each time, which can effectively prevent the clamping part from being directly affected by the laser, causing changes in the material properties of the part and damage to the clamping part. It ensures that the waste carbide plate is stably clamped during the cleaning process, reducing problems such as uneven cleaning or accidental movement caused by unstable clamping.

[0058] Advantage three, by utilizing the different rotation angles and directions of the switching member 245, initially, the clamping member 244 supports from its lower surface, which can provide stable support to prevent it from displacement or shaking during the cleaning process. When switching, the clamping member 244 supports the cleaned surface of the waste carbide plate to avoid certain areas of the surface of the waste carbide plate from being unable to be fully cleaned due to the obstruction of the clamping member 244, forming a cleaning blind spot, thereby facilitating comprehensive and dead-angle cleaning of the entire surface of the waste carbide plate, thereby improving the cleaning quality.

[0059] Advantage four, the limiting long plate 24422 and the limiting short plate 24441 in the clamping member 244 are both arranged in an L shape, and the vertical plate position is provided with an inclined surface. Since the limiting long plate 24422 and the limiting short plate 24441 only clamp more than half of the side wall of the waste carbide plate, rather than the entire side wall, during the laser cleaning process, the unclamped part will not be blocked by the clamping member 244, which enables the laser beam of the cleaning equipment to more fully irradiate the surface of the alloy plate, reduce the cleaning blind area, and improve the cleaning effect.

[0060] Advantage five, when the switching member 245 is used to switch the limiting long plate 24422 and the limiting short plate 24441, during the switching process, the limiting block 2433 extends out, and cooperates with the limiting groove 2434 inside it to support the waste carbide plate, and can make up for the gap when the limiting long plate 24422 has just separated from the waste carbide plate and the limiting short plate 24441 has not yet limited the waste carbide plate, thereby preventing the waste carbide plate from falling due to the sudden loss of support from the limiting long plate 24422 and the limiting short plate 24441, causing damage to the waste carbide plate. The limiting member 243 continues to support the waste carbide plate during the switching process, which can effectively prevent the waste carbide plate from falling, thereby ensuring the stability and safety of the entire switching process.

[0061] Advantage six, when the limit block 2433 in the limit member 243 cooperates with the limit groove 2434 inside it to support and limit the waste carbide plate, since the limit block 2433 approaches the side wall of the waste carbide plate from the middle of both sides of the waste carbide plate simultaneously, when the limit block 2433 is completely in contact with the waste carbide plate, the waste carbide plate can be kept stable during the switching process of the limit long plate 24422 and the limit short plate 24441, without sudden shaking or displacement, and a smooth transition can be achieved. In addition, when the limit block 2433 approaches the waste carbide plate from both sides of the waste carbide plate simultaneously, it can ensure that the waste carbide plate is always in the center position, thereby ensuring the continuity and accuracy of the cleaning process and avoiding the need to readjust the cleaning parameters or reposition due to changes in the position of the waste carbide plate.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
