Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to an intelligent welding device and method for high magnetic induction steel. Background Technology

[0002] In existing technologies, silicon steel, as a high-magnetic-induction steel, is often used in the processing of iron cores for various electromechanical equipment. After the silicon steel coil is cut, some end pieces are generated. These end pieces are naturally curved. To improve the utilization rate of the material, these end pieces are usually recycled and reused. One recycling method is to weld two end pieces of silicon steel sheets along the curved edge to form a larger curved silicon steel sheet for subsequent processing. However, during the welding process, because the dimensions of the end pieces are irregular, the edges need to be cut to be consistent before welding. In addition, the curvature of each end piece is inconsistent, so the edges of the two silicon steel sheets need to be spliced ​​to the same curvature before welding. Therefore, for the welding of silicon steel sheet end pieces, cutting, straightening and alignment are required before welding, resulting in low welding efficiency.

[0003] In summary, this application proposes an intelligent welding device and method for high magnetic induction steel, which improves the aforementioned technical problems. Summary of the Invention

[0025] In a further preferred embodiment of the present invention, such as Figures 9-11 As shown, it also includes a second linear slide rail 401, a third electric slider 402, and a cleaning insert 403; two front-to-back symmetrical second linear slide rails 401 are fixedly connected to the lower side of the ring frame 2; a third electric slider 402 is slidably connected to each second linear slide rail 401; two cleaning inserts 403 are fixedly connected to each third electric slider 402 through a connecting plate; each cleaning insert 403 is nested and engaged with a corresponding groove 5002.

[0026] In a further preferred embodiment of the present invention, such as Figure 12 and Figure 13 As shown, both cleaning blocks 403 on the left side are equipped with air supply channels 40301; the air supply channels 40301 are connected to an external air pump device.

[0027] In this embodiment, in the initial state, such as Figure 1 As shown, the pressure plate 5 and its connecting parts are located on the upper side of the ring of the fixing frame 1, and the pressure plate 5 is located on the upper side of the ring frame 2. The operator first places the silicon steel sheet 6 vertically, so that the silicon steel sheet 6 is close to the front support plate 3, and the outline dimension of the silicon steel sheet 6 is larger than the outline dimension of the support plate 3. Since the silicon steel sheet 6 is in a vertical state at this time, the upper, lower, front, and rear edges of the silicon steel sheet 6 are close to the corresponding edge of the support plate 3. Then, the upper edge of the silicon steel sheet 6 is manually inserted into the clamping groove 2001. Figure 2 and Figure 3As shown, the linear push rod on the ring frame 2 drives the front clamping plate 4 to clamp the upper edge of the silicon steel sheet 6, thereby fixing the silicon steel sheet 6 onto the ring frame 2. Then, the first driving component 203 on the front side adjusts the height of the front pressure plate 5, leaving a gap between the front suction plate 5001 and the ring frame 2 that matches the thickness of the silicon steel sheet 6. Taking the view from front to back in the figure as a reference, the first electric slider 202 on the front side is controlled to rotate 90 degrees counterclockwise on the corresponding annular slide rail 201, thereby driving the front pressure plate 5 and the suction plate 5001 to rotate 90 degrees counterclockwise. The plate 5001 rotates to the left side of the ring frame 2. During the rotation of the suction plate 5001, the left edge of the suction plate 5001 continuously scrapes the surface of the silicon steel sheet 6, thereby smoothing the silicon steel sheet 6. Under the limiting action of the suction plate 5001, the silicon steel sheet 6 is tightly attached to the surface of the ring frame 2 and the front support plate 3, thus achieving the fixing operation of the front silicon steel sheet 6. Considering that the recycled silicon steel sheets 6 are of different sizes, the edges of the silicon steel sheets 6 need to be cut to a uniform size before welding to facilitate the butt joint of the weld.

[0028] The following is a detailed description of the cutting operation of the silicon steel sheet 6. After the silicon steel sheet 6 on the front side is attached to the ring frame 2 and the support plate 3, the second electric slider 206 and its connecting parts are controlled to move forward on the corresponding first linear slide rail 205, so that the laser welding gun 210 moves to align with the junction of the front edge and the lower edge of the front support plate 3. The second drive unit 209 is controlled to bring the laser welding gun 210 close to the surface of the front silicon steel sheet 6. It should be noted that at this time, the laser welding gun 210 needs to be switched to the cutting mode. The silicon steel sheet 6 is penetrated by the high-power laser. At the same time, as shown in the figure, with the view from front to back as the reference, the arc slider 208 is controlled to slide clockwise on the arc slide rail 207, thereby driving the laser welding gun 210 to rotate clockwise along the front edge of the front support plate 3. In this way, the front edge of the silicon steel sheet 6 is cut by the laser welding gun 210. It is explained here that servo motors are provided at both the left and right ends of the arc-shaped slider 208 to ensure that the arc-shaped slider 208 can slide smoothly between the upper and lower arc-shaped slide rails 207. The distance between the two arc-shaped slide rails 207 is used to avoid the connecting rod used to connect the support plate 3 and the ring frame 2. When the laser welding gun 210 moves clockwise to the junction of the front edge and the upper edge of the support plate 3, the second electric slider 206 is located on the upper arc-shaped slide rail 207 and controls the arc-shaped slider 208 to stop sliding. Simultaneously, the second electric slider 206 drives the laser welding gun 210 to move backward, so that the laser welding gun 210 cuts the silicon steel sheet 6 along the upper edge of the support plate 3. When the laser welding torch 210 moves to the junction of the upper and rear edges of the support plate 3, the arc-shaped slider 208 is controlled to rotate the laser welding torch 210 counterclockwise to the junction of the rear and lower edges of the support plate 3, so that the laser welding torch 210 cuts the silicon steel sheet 6 along the rear edge of the support plate 3; then the arc-shaped slider 208 is controlled to stop moving, and the second electric slider 206 is controlled to move the laser welding torch 210 forward, so that the laser welding torch 210 cuts the silicon steel sheet 6 along the lower edge of the support plate 3; In summary, by cooperating and moving the second electric slider 206 and the arc slider 208, the laser welding gun 210 is driven to cut the silicon steel sheet 6 along the periphery of the support plate 3, so that the edge size of the silicon steel sheet 6 is consistent with the edge size of the support plate 3. Similarly, after the silicon steel sheet 6 on the front side is cut, the other silicon steel sheet 6 is fixed in the groove 2001 on the rear side using the same steps, and the silicon steel sheet 6 is tightly attached to the surface of the ring frame 2 and the rear support plate 3 by the suction plate 5001 on the rear side. Then, the laser welding gun 210 is used to cut the silicon steel sheet 6 on the rear side, so that the outline size of the two silicon steel sheets 6 is consistent, so as to facilitate the butt joint of the weld. It should be noted that the edges of the two grooves 5002 on the same suction plate 5001 are aligned with the upper and lower edges of the corresponding support plate 3. When cutting the upper and lower edges of the silicon steel sheet 6, the grooves 5002 avoid the laser, so as to ensure that the laser can completely penetrate the silicon steel sheet 6.

[0029] After both silicon steel sheets 6 are cut, welding begins. An external air extraction device is used to extract air from the two suction plates 5001, creating suction at the suction holes 5003. This causes the silicon steel sheets 6 to adhere to the surface of the suction plates 5001. Then, the first driving component 203 moves the pressure plate 5 and its connecting parts away from the ring frame 2, causing the suction plates 5001 to detach the corresponding silicon steel sheets 6 from the support plate 3. Simultaneously, the silicon steel sheets 6 are separated from the cutting waste. Then, using a front-to-back view, the first electric slider 202 on the front side rotates the corresponding suction plate 5001 90 degrees counterclockwise, and simultaneously, the first electric slider 202 on the rear side rotates the corresponding suction plate 5001 90 degrees clockwise, causing the two suction plates 5001 to come into contact with each other, and the two silicon steel sheets 6 to come into contact with each other as well. Then, the first driving component 203 moves the corresponding pressure plate 5 closer to the ring frame 2, causing the two silicon steel sheets 6 to come into contact with the bottom of the ring frame 2. The state at this point is as follows: Figure 10 As shown; Then, the second electric slider 206 is controlled to move the laser welding gun 210 to the middle position of the support frame 204, with the laser welding gun 210 facing the edge junction of the two silicon steel sheets 6. Then, the arc slider 208 is controlled to adjust the laser welding gun 210 toward the through groove 2002, and to make the laser welding gun 210 face the right edge of the two silicon steel sheets 6. Figure 11 As shown, the second driving component 209 is controlled to bring the laser welding gun 210 close to the junction of the two silicon steel sheets 6. Then, the arc-shaped slider 208 is controlled to drive the laser welding gun 210 to rotate counterclockwise to the left and right edges of the two silicon steel sheets 6. During the rotation of the laser welding gun 210, the laser welding gun 210 is switched to welding mode. At this time, by adjusting the pulse frequency of the laser, the laser welds the two silicon steel sheets 6 together. This achieves the welding of the two silicon steel sheets 6. After the two silicon steel sheets 6 are welded, the first driving component 203 is controlled to disengage the suction plate 5001 and the silicon steel sheet 6 from the bottom of the ring frame 2. Then, the suction plate 5001 is controlled to stop sucking air so that the workers can take out the welded silicon steel sheet 6.

[0030] Compared with conventional welding methods, before welding, the silicon steel sheet 6 is flattened by the suction plate 5001 to ensure that the silicon steel sheet 6 is in a smooth arc state, and the silicon steel sheet 6 is clamped and fixed by the support plate 3 so that the laser welding gun 210 can cut and trim the silicon steel sheet 6 to ensure that the silicon steel sheet 6 to be welded is consistent in size. During welding, the suction plate 5001 and the ring frame 2 work together to limit the bending arc of the two silicon steel sheets 6, so that the bending arc of the two silicon steel sheets 6 is consistent. Therefore, there is no need to use an additional support structure to limit the welding of the silicon steel sheet 6, thus improving welding efficiency and quality.

[0031] In this embodiment, during the process of laser welding torch 210 cutting silicon steel sheet 6, molten slag will inevitably be sputtered out. The slag will adhere to the edges of support plate 3 and suction plate 5001. If not handled in time, the slag will solidify on the edges of support plate 3 and suction plate 5001, making subsequent cleaning difficult. At the same time, the solidified slag will affect the surface flatness. Therefore, in the initial state, the protrusion 30401 on the front scraper ring 304 is in contact with the rear edge of the corresponding through groove 2002 and gap 3001. After the silicon steel sheet 6 is cut, the control clamp 4 releases the clamp on the silicon steel sheet 6 scrap, and then the control of the front fourth drive member 303 drives the front... The scraper ring 304 moves forward, causing the protrusion 30401 to slide forward within the corresponding clamping groove 2001 and gap 3001. This allows the protrusion 30401 to scrape away the molten slag adhering to the upper and lower edges of the support plate 3. Simultaneously, the protrusion 30401 scrapes the surface of the corresponding groove 5002, removing the molten slag adhering to the surface of the groove 5002. Furthermore, as the protrusion 30401 moves forward, it simultaneously pushes the silicon steel sheet 6 waste forward, causing the silicon steel sheet 6 waste to detach from the front of the support plate 3. This achieves automatic detachment of the silicon steel sheet 6 waste, eliminating the need for manual removal and improving the processing efficiency of the silicon steel sheet 6.

[0032] In this embodiment, further, as Figure 5 and Figure 6 As shown, during the process of laser welding gun 210 cutting the front edge of silicon steel sheet 6, the direct drive motor 301 is controlled to drive scraper 302 to rotate, so that the rear edge of scraper 302 is aligned with the front edge of support plate 3. Thus, during the process of cutting the front edge of silicon steel sheet 6, scraper 302 simultaneously scrapes the front edges of support plate 3 and suction plate 5001 to clean the slag on the front edges of support plate 3 and suction plate 5001. Similarly, during the cutting of the rear edge of the silicon steel sheet 6, the scraper 302 cleans the slag on the rear edge of the support plate 3 and the suction plate 5001. In summary, during the cutting of the silicon steel sheet 6, the welding slag on the four edges of the support plate 3 and the suction plate 5001 is scraped off simultaneously, reducing the workload of cleaning the slag afterward. At the same time, it can ensure the flatness of the surface of the support plate 3 and the suction plate 5001 and prevent the protruding slag from scratching the surface of the silicon steel sheet 6.

[0033] In this embodiment, it is also considered that during the welding of silicon steel sheet 6, although conventional welding equipment can spray protective gas (specifically argon) to protect the weld pool area, the welding part is exposed to the outside air. If a strong airflow is encountered, the protective gas is easily blown away, resulting in a decrease in the protection effect on the weld pool. Therefore, the above problem is solved by adding a baffle 305. In the initial state, the baffle 305 covers the through groove 2002. When the suction plate 5001 drives the silicon steel sheet 6 to adhere to the bottom of the ring frame 2, the through groove 2002 is then protected by the upper baffle 305 and the lower suction plate 5001. 1. The laser welding gun 210 is moved closer to the silicon steel sheet 6 by the second drive unit 209, so that the laser welding gun 210 and the scraper 302 are inserted into the corresponding round hole and strip groove on the baffle 305 respectively. Then, the laser welding gun 210 is controlled to weld along the arc weld of the silicon steel sheet 6. During this process, the baffle 305 rotates synchronously with the laser welding gun 210 and always fits against the top of the through groove 2002. In this way, the through groove 2002 is isolated by the baffle 305 and the suction plate 5001, preventing the external airflow from blowing away the protective gas and ensuring the welding quality.

[0034] In this embodiment, it is also considered that during the welding process, argon gas needs to be continuously sprayed to protect the molten pool area. However, the argon gas in the through groove 2002 will escape into the outside air through the groove 5002. Therefore, during the welding process, argon gas needs to be continuously supplied, resulting in most of the argon gas escaping into the outside air and being unable to be recovered. This means that purchasing argon gas accounts for a portion of the welding cost. To reduce the cost of purchasing argon gas, after the suction plate 5001 drives the silicon steel sheet 6 to adhere to the bottom of the ring frame 2, the third electric slider 402 is controlled to move towards the center side of the ring frame 2 on the second linear slide rail 401, thereby driving the corresponding cleaning insert 403 to insert into the corresponding groove 5002. At this time, the state is as follows. Figures 11-13As shown, since the groove 5002 is blocked by the cleaning insert 403, it should be noted that at this time, the two suction plates 5001 are in contact with each other. The two suction plates 5001, the ring frame 2, the baffle 305, and the cleaning insert 403 together block the through groove 2002, making the through groove 2002 a closed space that is not connected to the outside air. Then, the external air pump device is controlled to evacuate the air supply pipe 404 on the right side, thereby removing the air from the through groove 2002. Then, the external air pump device is controlled to supply argon gas to the air supply pipe 404 on the left side, so that the through groove 2002 is filled with argon. Argon gas is then returned to the external air pump device via the right-side gas supply pipe 404, causing the argon gas to circulate from left to right within the channel 2002. The laser welding torch 210 is then controlled to perform welding operations. After welding is completed, the external air pump device is controlled to evacuate the right-side gas supply pipe 404 to recover the argon gas within the channel 2002. Subsequently, the external air pump device is controlled to resupply air to the left-side gas supply pipe 404, restoring normal pressure within the channel 2002. This, combined with the cleaning insert 403, seals the space within the channel 2002. This allows argon gas to circulate and be recovered within the channel 2002, reducing argon waste and lowering welding costs. Furthermore, using a front-to-back view as a reference, as the laser welding torch 210 rotates clockwise along the arc-shaped weld seam of the silicon steel sheet 6, it simultaneously drives the scraper 302 to rotate clockwise. This causes the front and rear edges of the scraper 302 to scrape the front and rear edges of the channel 2002, respectively. The scraper 302 promptly removes the slag splashed onto the channel 2002, preventing slag from solidifying on the surface of the channel 2002, thus reducing the difficulty of cleaning the channel 2002. The lower edge of plate 302 simultaneously scrapes the welded surfaces of the two silicon steel sheets 6. During this process, argon gas is kept blowing from the left side to the right side of scraper 302 through the ventilation holes 30201 on scraper 302. At the same time, the ventilation holes 30201 intercept the slag mixed in the argon gas, causing the slag to remain on the left side of scraper 302. As scraper 302 pushes the slag to the left, the argon gas blows from left to right to ensure that the scraped slag does not fall on the unwelded parts on the left side, thereby preventing slag from mixing into the weld and forming a whole, thus improving the welding quality.

[0035] In this embodiment, further, when the laser welding torch 210 welds to the left edge of the silicon steel sheet 6, the laser welding torch 210 is stopped. Using a front-to-back view as a reference, the arc-shaped slider 208 is then controlled to continue rotating the laser welding torch 210 and the scraper 302 clockwise until the scraper 302 is aligned with the groove 5002 on the left side. This pushes the scraped slag into the groove 5002. Then, argon gas is recovered according to the above steps, and the through-slot 2002 is filled with air. An external air pump is then controlled to supply air to the rear left-side gas delivery channel 40301, while simultaneously evacuating air from the front left-side gas delivery channel 40301. The airflow flows from back to front within the left groove 5002, blowing the molten slag out of the groove 5002 into the through-slot 2002. The blown-out molten slag is discharged through the front air supply channel 40301. In summary, the through-slot 2002 is sealed by the baffle 305, suction plate 5001, and cleaning block 403, thus preventing external airflow from affecting the welding process. This also reduces argon gas waste and lowers welding costs. Furthermore, during each welding process, the scraper 302 promptly scrapes off the molten slag adhering to the surface of the through-slot 2002 and uses airflow to discharge the molten slag from the groove 5002, eliminating the need for manual slag cleaning and reducing the maintenance difficulty of the welding equipment.

[0036] Example 2: Based on Example 1, as follows Figure 7 and Figure 8 As shown, the suction plate 5001 is made of elastic material; the suction plate 5001 is detachably connected to the corresponding pressure plate 5, and also includes a third driving component 211; a third driving component 211 is fixedly connected to each pressure plate 5, and the third driving component 211 is an electric push rod; the telescopic end of the third driving component 211 is fixedly connected to the adjacent suction plate 5001.

[0037] Considering that the silicon steel sheet 6 needs to undergo weld inspection after welding, the first driving component 203 is controlled to move the pressure plate 5, suction plate 5001, and silicon steel sheet 6 downwards to the lowest point after welding is completed. At this point, the silicon steel sheet 6 is completely detached from the bottom of the ring frame 2, while the suction plate 5001 still holds the silicon steel sheet 6. Then, the third driving component 211 is controlled to move the suction plate 5001 and silicon steel sheet 6 upwards, causing the suction plate 5001 to detach from the pressure plate 5. Since the suction plate 5001 is made of elastic material, after the suction plate 5001 detaches from the pressure plate 5, the suction plate 5... Under its own elastic force, 001 returns from a curved shape to a flat shape, thereby deforming the silicon steel sheet 6 and the weld into a flat shape. Then, the third driving component 211 is controlled to move the suction plate 5001 and the silicon steel sheet 6 downward, so that the suction plate 5001 re-fits the pressure plate 5. This is repeated 4-5 times, so that the silicon steel sheet 6 can switch between a curved and a straight state multiple times, thereby subjecting the welded part of the silicon steel sheet 6 to bending stress. Then, the welded part of the silicon steel sheet 6 is manually observed to check for incomplete welds or cracks, thereby testing the weld strength of the silicon steel sheet 6.

[0038] A smart welding method for high magnetic induction steel includes the following steps: S1: Feeding: First, fix the silicon steel sheet 6 on the support plate 3, and then straighten the silicon steel sheet 6 through the suction plate 5001 and the support plate 3; S2: Cutting, the four edges of the silicon steel sheet 6 are cut by the laser welding gun 210 to make the outline dimensions of the two silicon steel sheets 6 consistent, so as to facilitate the butt joint of the weld. S3: Welding, two silicon steel sheets 6 are welded by laser welding gun 210, and during the welding process, the slag splashed on the through groove 2002 is scraped off in time by scraper 302 to prevent the slag from solidifying on the surface of the through groove 2002. S4: Inspection. After welding is completed, the suction plate 5001 and the pressure plate 5 move together to switch the silicon steel sheet 6 between a bent and a straight state multiple times, so that the welded part of the silicon steel sheet 6 is subjected to bending stress, thereby inspecting the weld strength of the silicon steel sheet 6.
