In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] Example 1

[0065] like Figure 1 As shown, a silicon steel sheet welding device includes: a frame 10; a first main board 20, fixedly connected to one side of the top of the frame 10, and a silicon steel sheet is placed on the first main board 20; a second main board 30, movably arranged on the other side of the top of the frame 10 along the X-axis direction, and a feeding device 40 is provided on the side of the second main board 30 away from the first main board 20, and the feeding device 40 is used to transport the silicon steel sheet to the second main board 30; a welding device 50, movably arranged above the frame 10 along the Y-axis direction, and the welding device 50 is used to weld the silicon steel sheets in the first main board 20 and the second main board 30.

[0066] Further explanation, the first main board 20 and the second main board 30 are respectively arranged on the top of the frame 10, and silicon steel sheets are arranged in the first main board 20 and the second main board 30. The two silicon steel sheets are welded by a welding device 50 to obtain a whole silicon steel sheet with a larger volume. Further explanation, the first main board 20 is fixedly connected to the frame 10, and the silicon steel sheet in the first main board 20 is also immovable. With the first main board 20 fixedly arranged below the welding device 50, the second main board 30 can move laterally at the top of the frame 10 along the X-axis direction. Specifically, a guide rail and a slider are arranged at the bottom of the second main board 30. The slider moves on the guide rail to drive the second main board 30 to move along the X-axis direction. When the second main board 30 is idle, the second main board 30 will move toward the direction of the feeding device 40 until the second main board 30 is connected to the feeding device 40. At this time, the silicon steel sheets are transferred from the feeding device 40 to the second main board 30, and the second main board 30 moves toward the direction of the first main board 20 until the silicon steel sheets on the second main board 30 and the silicon steel sheets on the first main board 20 are against each other. Since the welding device 50 is arranged above the frame 10 along the Y-axis direction (specifically, it is arranged directly above the position where the silicon steel sheets of the first main board 20 and the silicon steel sheets of the second main board 30 are connected), the welding device 50 can perform welding along the gap between the two silicon steel sheets, thereby integrating a larger silicon steel sheet.

[0067] The welding process of the utility model does not require human operation, realizes the automation of welding two silicon steel sheets, reduces errors caused by human operation, and improves the welding accuracy; the first main board 20 is fixedly connected to the frame 10, so that the position of the silicon steel sheet on the first main board 20 is fixed, which facilitates the alignment of the silicon steel sheet transferred by the second main board 30 with the silicon steel sheet on the first main board 20, and facilitates the subsequent welding device 50 to weld the two silicon steel sheets.

[0068] like Figure 2 As shown, in order to avoid collision between the first main board 20 and the second main board 30, the present embodiment also includes: a baffle 21, which is arranged on the side opposite to the first main board 20 and the second main board 30, and the baffle 21 and the first main board 20 are perpendicular to each other; a buffer 22, which is arranged at the bottom of the first main board 20, and the buffer 22 and the baffle 21 are perpendicular to each other.

[0069] To further explain, the baffle 21 is arranged between the first main board 20 and the second main board 30, specifically, it is arranged on the edge of the side opposite to the first main board 20 and the second main board 30, and the baffle 21 and the first main board 20 are perpendicular to each other. The baffle 21 can well separate the first main board 20 and the second main board 30 to prevent the second main board 30 from hitting the first main board 20.

[0070] The buffer 22 is arranged at the bottom of the first main board 20 and extends toward the second main board 30. The buffer 22 and the slider at the bottom of the second main board 30 are at the same horizontal height. The buffer 22 is used to limit the moving distance of the slider in the X-axis direction to prevent the second main board 30 at the top of the slider from colliding with the first main board 20. At the same time, it can also effectively limit the collision between the silicon steel sheets on the second main board 30 and the silicon steel sheets on the first main board 20.

[0071] like Figure 3 As shown, the present embodiment is further described, the feeding device 40 includes: a belt conveyor 41, one end of which is connected to the second main board 30, and the belt conveyor 41 is used to convey the silicon steel sheets to the second main board 30; a platform 42, which is connected to the other end of the belt conveyor 41, and the platform 42 is provided with stacked silicon steel sheets; a loading device 43, which is movably arranged above the belt conveyor 41 and the platform 42 along the X-axis direction, and the loading device 43 sucks the silicon steel sheets on the platform 42 and transfers them to the belt conveyor 41.

[0072] Specifically, the loading device 43 includes a guide rail, a slider, a cylinder and a suction cup. The cylinder drives the suction cup to move in the Z-axis direction, thereby sucking the silicon steel sheet on the platform 42. After the suction cup sucks the silicon steel sheet, the silicon steel sheet is transported to the belt conveyor 41 (including a belt and a synchronous pulley, and the synchronous pulley drives the belt to operate) with the cooperation of the guide rail and the slider. The belt conveyor 41 transports the silicon steel sheet to the second main board 30, thereby completing the transportation of the silicon steel sheet from the platform 42 to the second main board 30. The transportation process of the silicon steel sheet is highly automated, does not require manual operation, is convenient and fast, and improves the handling efficiency of the silicon steel sheet.

[0073] This embodiment is further described as follows. Figure 4 As shown, the welding device 50 includes: a moving device 51, which is movably arranged above the frame 10 along the Y-axis direction; a welding gun 52, which is connected to one end of the moving device 51 close to the silicon steel sheet, and the welding gun 52 is driven by the moving device 51 to weld along the edge of the first main board 20.

[0074] Specifically, the moving device 51 includes a moving bracket, a guide rail and a slider. The moving bracket moves along the Y-axis direction with the cooperation of the guide rail and the slider. A welding gun 52 is arranged on the moving bracket. The welding gun 52 is used to weld the silicon steel sheets on the first main board 20 and the second main board 30. Specifically, the welding gun 52 is located directly above the edge of the first main board 20. Since the first main board 20 is fixedly arranged on the frame 10, the position of the first main board 20 will not change, and the position of the silicon steel sheets on the first main board 20 is also fixed. Therefore, the position of the weld can be determined, and the welding gun 52 can be directly arranged directly above the edge of the first main board 20. There is no need to additionally position the welding gun 52 before each welding, which saves the welding cycle.

[0075] Example 2

[0076] like Figure 5-6 As shown, in order to ensure that the silicon steel sheets on the first main board 20 and the second main board 30 do not move during welding, the present embodiment provides two clamping devices 60 that move along the Z-axis direction, and the two clamping devices 60 are respectively arranged on the adjacent sides of the first main board 20 and the second main board 30. The clamping devices 60 can respectively squeeze the silicon steel sheets on the first main board 20 and the second main board 30, so that the silicon steel sheets are tightly attached to the first main board 20 and the second main board 30, thereby improving the subsequent welding accuracy.

[0077] To further illustrate this embodiment, the clamping device 60 includes: a driving device 61, fixedly connected to the frame 10; a pull rod 62, one end of which is connected to the output end of the driving device 61, and the other end is connected to the pressure plate 63; the driving device 61 drives the pull rod 62 and the pressure plate 63 to move in the Z-axis direction, and the pressure plate 63 applies a force to the silicon steel sheet, so that the silicon steel sheet fits tightly with the first main board 20 or the second main board 30.

[0078] Specifically, the driving device 61 is a cylinder, and the pull rod 62 is connected to the output end of the cylinder. The cylinder drives the pull rod 62 to perform lifting and lowering movements in the Z-axis direction. Since the pressure plate 63 is connected to the pull rod 62, the pressure plate 63 is driven to lift and lower movements in the Z-axis direction. When the two silicon steel sheets are transported to the first main board 20 and the second main board 30 respectively, the driving device 61 will drive the pull rod 62 to move downward, thereby driving the pressure plate 63 to move downward. The pressure plate 63 applies a force to the silicon steel sheet, so that the silicon steel sheet is tightly fitted to the first main board 20 or the second main board 30.

[0079] Further explanation, the end of the pressing plate 63 in contact with the silicon steel sheet is inclined ( Figure 5 ), on the one hand, it can continuously apply a certain force to the silicon steel sheet to ensure that the silicon steel sheet does not move during welding; on the other hand, the inclined pressure plate 63 at one end can reduce the contact area with the silicon steel sheet to prevent the pressure plate 63 from scratching the silicon steel sheet.

[0080] Example 3

[0081] like Figure 7As shown, since there are various specifications of silicon steel sheets, in order to enable the welding equipment of the present invention to match silicon steel sheets of different sizes, the platform 42 of this embodiment also includes a fixing rod 421, an adjustment groove 422 and a sliding rod 423; wherein the fixing rod 421 is inserted into the platform 42, and is used to fix one side wall of the silicon steel sheet; the adjustment groove 422 is provided on one side of the fixing rod 421, and a sliding rod 423 that can slide along the adjustment groove 422 is provided in the adjustment groove 422, and the sliding rod 423 slides in the adjustment groove 422 according to the width of the silicon steel sheet and fixes the other side wall of the silicon steel sheet.

[0082] Specifically, the fixing rod 421 and the adjusting groove 422 are relatively arranged on both sides of the silicon steel sheet, so as to fix the two sides of the silicon steel sheet. Since the sliding rod 423 can slide in the adjusting groove 422, the distance between the fixing rod 421 and the sliding rod 423 can be changed, so that silicon steel sheets of different sizes can be placed between the two, which increases the diversity of welding equipment and is suitable for welding silicon steel sheets of different sizes.

[0083] Further explanation, in order to ensure that the silicon steel sheets do not move in the X-axis direction when stacked on the platform 42, a limit rod can be set at at least one end of the silicon steel sheet, which can limit the movement of the silicon steel sheet in the X-axis and ensure that the suction cup can stably absorb the silicon steel sheet.

[0084] Example 4

[0085] like Figure 8 As shown, the silicon steel sheet is transferred to the second main board 30 by the belt conveyor 41. Since the end of the silicon steel sheet close to the first main board 20 and the end of the second main board 30 close to the first main board 20 may not be in an aligned state, resulting in low subsequent welding quality and a large weld. Therefore, a first adjustment device 70 is provided in this embodiment. Specifically, the first adjustment device 70 is provided on the second main board 30. The first adjustment device 70 is used to adjust the welding position of the silicon steel sheet on the second main board 30;

[0086] To further explain, the first adjusting device 70 includes: a transverse moving device 71, which moves on the second main board 30 along the X-axis direction; a U-shaped base 72, which is arranged on the transverse moving device 71, and the U-shaped base 72 is provided with a suction cup device 73 which can move along the Y-axis direction, and the suction cup device 73 is used to absorb the silicon steel sheet.

[0087] Specifically, the transverse movement device 71 includes a guide rail and a slider, which are used to realize the movement of the U-shaped base 72 in the X-axis direction. The U-shaped base 72 is provided with a guide rail and a slider along the Y-axis direction. The suction cup device 73 realizes movement in the Y-axis direction through the guide rail and the slider, so as to facilitate the suction of the silicon steel sheet by the suction cup device 73 (including a suction cup and a cylinder, and the output end of the cylinder is connected to the suction cup). After the suction cup device 73 sucks the silicon steel sheet, the transverse movement device 71 drives the U-shaped base 72 and the suction cup device 73 to move in the X-axis direction. When one end of the silicon steel sheet is aligned with one end of the second main board 30, the transverse movement device 71 stops moving, and the suction cup device 73 places the silicon steel sheet on the second main board 30, waiting for the subsequent welding device 50 to weld the silicon steel sheet.

[0088] Example 5

[0089] like Figure 9-11 As shown, when the silicon steel sheets on the first main board 20 and the second main board 30 are welded, a large piece of silicon steel sheet is often manually moved away from the welding equipment. This process is time-consuming and labor-intensive, and there are certain safety risks. In order to overcome the above problems, a transporting device 80 is provided in this embodiment. The transporting device 80 is arranged on the side of the frame 10 opposite to the feeding device 40. The transporting device 80 is used to transport the welded silicon steel sheet out of the first main board 20.

[0090] To further explain, the transporting device 80 includes: a unloading device 81, which is connected to the side of the first main board 20 facing away from the second main board 30; a second adjusting device 82, which is arranged on the first main board 20, and the structure of the second adjusting device 82 is consistent with that of the first adjusting device 70; the second adjusting device 82 transports the welded silicon steel sheets to the unloading device 81, and the unloading device 81 transports the silicon steel sheets out of the welding equipment.

[0091] To further explain, the unloading device 81 includes: a connecting plate 811, which is connected to the side of the first main board 20 facing away from the second main board 30; two baffle bars 812, one baffle bar 812 is fixedly connected to the connecting plate 811, and the other baffle bar 812 is movably arranged on the connecting plate 811 along the Y-axis direction, and the silicon steel sheet is transported between the two baffle bars 812 under the action of the second adjusting device 82; a first pressing wheel 813, and a plurality of first pressing wheels 813 for pressing and transporting the silicon steel sheet are arranged between the two baffle bars 812.

[0092] The second adjusting device 82 transports the welded silicon steel sheets to the connecting plate 811. Two baffles 812 are provided on the connecting plate 811. The width of the two baffles 812 is consistent with the width of the silicon steel sheets. After the silicon steel sheets enter between the two baffles 812, they will be squeezed by the first pressure wheel 813 to ensure that the silicon steel sheets are flat and do not deform in the Z-axis direction. Further explanation: the distance between the two baffles 812 is adjustable, one of which is fixedly connected to the connecting plate 811, and the other baffle 812 is movably connected to the connecting plate 811. The installation method of the movable baffle 812 can refer to the installation method of the slide bar 423 and the adjustment slot 422 in Example 3, so that the distance between the two baffles 812 can be changed to adapt to silicon steel sheets of different sizes.

[0093] In order to further ensure the flatness of the silicon steel sheet, an H-shaped bracket 814, a second pressure wheel 815 and a roller 816 are also provided on the side of the connecting plate 811 away from the first main board 20, wherein the second pressure wheel 815 is sleeved on the H-shaped bracket 814, the roller 816 is located below the second pressure wheel 815, and the two ends of the roller 816 are movably connected to the H-shaped bracket 814.

[0094] The silicon steel sheet is further rolled by the second pressing wheel 815 so that the thickness of the silicon steel sheet is kept uniform. Furthermore, a pressure regulating device is provided on the top of the H-shaped bracket 814. The pressure between the second pressing wheel 815 and the roller 816 can be adjusted by the pressure regulating device to ensure that the thickness of the silicon steel sheet is kept within the required range.
