Silicon steel sheets are the main components of the iron core. Silicon steel sheets are processed into five shapes: upper jaw sheets, lower jaw sheets, left sheets, right sheets, and middle column sheets. These five shapes of silicon steel sheets can be used in the production of iron cores after being stacked according to a certain rule. Before stacking the five shapes of silicon steel sheets, it is necessary to clamp both sides of the silicon steel sheets, and then use the guiding mechanism to guide the ends of the silicon steel sheets, and adjust the position of the silicon steel sheets so that after the external grasping equipment grasps the silicon steel sheets, the silicon steel sheets can be stacked in an offset manner for subsequent use.

[0067] Reference Figure 1-6 , an embodiment of the present invention provides a positioning device for stacking transformer silicon steel sheets, comprising:

[0068] A carrying platform 1 having a first through slot 2 and a second through slot 3;

[0069] The clamping mechanism includes a plurality of clamping assemblies, each of which includes a first movable plate 4 and a second movable plate 5 which are relatively arranged at the lower end of the first through slot 2 and can move relative to or towards each other along the first through slot 2. The first movable plate 4 and the second movable plate 5 are both provided with a clamping wheel 6, which is configured to be able to rotate in a circumferential direction, and the upper end thereof passes through and exceeds the first through slot 2, and is used to clamp both sides of the transformer silicon steel sheet;

[0070] The guiding mechanism includes a base 7 which is arranged at the lower end of the second through groove 3 and can move along the second through groove 3. A guiding assembly is arranged on the base 7. The guiding assembly includes a first rotating rod 8 and a second rotating rod 9 which are connected in a cross-rotating manner. The first rotating rod 8 and the second rotating rod 9 are both provided with a first push plate 10. The two first push plates 10 are both configured to be able to be independently lifted and lowered relative to the base 7 so as to guide the end of the transformer silicon steel sheet.

[0071] In a specific embodiment, a coating is applied to one side of the carrying platform 1 for carrying the transformer silicon steel sheet. The coating is used to reduce the friction between the transformer silicon steel sheet and the carrying platform, improve the surface smoothness of the carrying platform, and facilitate the positioning operation of the transformer silicon steel sheet.

[0072] In a specific embodiment, the material of the carrying platform 1 is aluminum.

[0073] In a specific embodiment, the clamping mechanism includes four clamping components evenly distributed along the extension direction of the carrying platform 1. Of course, it should be appreciated that the clamping components in the present invention can also be set to other numbers, and the present invention is not limited thereto. Any number of clamping components that can achieve the same technical effect of the present invention is within the protection scope of the present invention.

[0074] In one embodiment, each clamping assembly further includes a third driving assembly for driving the first movable plate 4 and the second movable plate 5 to move relative to or toward each other along the first through slot 2 .

[0075] In one embodiment, the clamping mechanism further includes a third driving unit 11 for driving the third driving assembly and a transmission rod 12 , and one end of the transmission rod 12 is connected to the transmission end of the third driving unit 11 .

[0076] In a specific embodiment, the third drive assembly includes a third screw rod 13 and a third guide rail 14, one end of the third screw rod 13 is gear-connected to the transmission rod 12, and the other end thereof is threadedly connected to the first movable plate 4 and the second movable plate 5, and the third guide rail 14 is arranged on the supporting platform 1 to guide the movement of the first movable plate 4 and the second movable plate 5.

[0077] In a specific embodiment, two fixed shafts 15 are symmetrically arranged on the first movable plate 4 and the second movable plate 5 , and the clamping wheel 6 is sleeved on the fixed shafts 15 .

[0078] In a specific embodiment, the first through slots 2 and the clamping wheels 6 are arranged in a one-to-one correspondence.

[0079] Specifically, the clamping wheel can move relatively under the drive of the first movable plate and the second movable plate. When contacting the transformer silicon steel sheet, the clamping wheel is in a rotating state, and the friction between the clamping wheel and the transformer silicon steel sheet is small. In the process of gradually clamping the transformer silicon steel sheet, the problem of the transformer silicon steel sheet being stuck or deformed can be avoided, and the clamping or loosening of the transformer silicon steel sheet is convenient. In addition, the clamping mechanism can also meet the requirements of clamping both sides of the transformer silicon steel sheet with a width of 40 to 440 mm and a length of 400 to 2000 mm, so as to improve the utilization rate of the positioning device.

[0080] In a specific embodiment, the guiding mechanism also includes a second drive assembly, which includes a second drive unit 16, a second screw rod 17 and a second guide rail 18. One end of the second screw rod 17 is connected to the transmission end of the second drive unit 16, and the other end thereof is threadedly connected to the base 7. The second guide rail 18 is connected to the supporting platform 1 for guiding the movement of the base 7.

[0081] Specifically, since the transformer silicon steel sheets need to be staggered a certain distance when stacked, and the second guide rail has a first track and a second track relatively arranged on both sides of the second slide groove, when the second driving unit drives the second screw rod, the base can move along the second slide groove through the interaction with the second screw rod and the guidance of the first track and the second track to adjust the distance between the first push plate and the transformer silicon steel sheet. At the same time, the position of the transformer silicon steel sheet can be adjusted, so that after the external grasping equipment grasps the transformer silicon steel sheet, the transformer silicon steel sheet can be staggered and stacked, which is convenient for subsequent use.

[0082] In a specific embodiment, the guiding assembly also includes a first drive assembly, which includes a first screw rod 19, a synchronous belt 20, a first drive unit 21, a first guide rail 22, a first connecting seat 23 and a second connecting seat 24. The first screw rod 19 is connected to the transmission end of the first drive unit 21 through the synchronous belt 20, and the first connecting seat 23 and the second connecting seat 24 are relatively arranged on the first screw rod 19. The upper ends of the two are respectively connected to the first rotating rod 8 and the second rotating rod 9, and the lower ends of the two are connected to the first guide rail 22.

[0083] Specifically, the first drive unit is arranged at the lower end of the base, and the first screw rod and the first guide rail are arranged on the lower sides of the first rotating rod and the second rotating rod, so that when the first drive unit drives the first connecting seat and the second connecting seat to move relative to or toward each other, the angle between the first rotating rod and the second rotating rod can be adjusted to adapt to the end shape of the transformer silicon steel sheet and achieve compatibility with five shapes of transformer silicon steel sheets.

[0084] In one embodiment, the adjustment range of the included angle between the first rotating rod 8 and the second rotating rod 9 is 30-60°.

[0085] Specifically, the first rotating rod and the second rotating rod can complete the angle conversion within 0.6S according to the end angle of the transformer silicon steel sheet placed on the supporting platform. Compared with the existing method that requires manual replacement and adjustment of the guiding mechanism, the present invention effectively improves the guiding efficiency of the end of the transformer silicon steel sheet through the mutual cooperation of the first rotating rod and the second rotating rod, so that the guiding mechanism can be compatible with more end angles of the transformer silicon steel sheet, and the utilization rate is higher.

[0086] In one embodiment, the first rotating rod 8 and the second rotating rod 9 are both provided with a second push plate 25 for cooperating with the first push plate 10 to align the end of the transformer silicon steel sheet.

[0087] In a specific embodiment, both the first push plate 10 and the second push plate 25 have a boss 26 for limiting the position of the transformer silicon steel sheet.

[0088] In one embodiment, a lifting assembly is disposed on both the first rotating rod 8 and the second rotating rod 9 . The lifting assembly includes a connecting plate 27 and a cylinder 28 for driving the connecting plate 27 to lift and lower. The upper end of the connecting plate 27 is connected to the first push plate 10 .

[0089] Specifically, the first push plate and the second push plate on the first rotating rod and the second rotating rod are both arranged along the extension direction thereof, the upper end of the second push plate exceeds the second sliding groove, and the height is fixed.

[0090] When it is necessary to correct the end of any transformer silicon steel sheet of the five shapes, the cylinder on the first rotating rod or the second rotating rod can drive the first push plate thereon to move upward or downward respectively, so as to correct the end of any transformer silicon steel sheet, specifically including the following three implementation methods:

[0091] In the first embodiment, only the first push plate 10 of the first rotating rod 8 moves upward, and the first push plate 10 and the second push plate 25 on the first rotating rod 8 are used together to align the ends of the transformer silicon steel sheets except the center column sheet 29 .

[0092] In the second embodiment, only the first push plate 10 of the second rotating rod 9 moves upward, and the first push plate 10 and the second push plate 25 on the second rotating rod 9 are used together to align the ends of the transformer silicon steel sheets except the center column sheet 29 .

[0093] In the third embodiment, the first push plate 10 in the first rotating rod 8 and the first push plate 10 in the second rotating rod 9 move upward simultaneously to align the end of the center column piece 29 .

[0094] Specifically, the ends of the upper jaw piece, the lower jaw piece, the left piece and the right piece all have an angle that can be directed toward the first rotating rod and / or the second rotating rod. Therefore, when only the first push plate of the first rotating rod or the second rotating rod moves up, it can simultaneously meet the needs of guiding the ends of other transformer silicon steel sheets except the center column sheet, making the guiding mechanism more flexible and able to meet the needs of precise guiding of the ends of transformer silicon steel sheets of five shapes.

[0095] When the positioning device of the present invention is in use, first, the transformer silicon steel sheet to be positioned needs to be placed on the carrying platform through an external feeding device, then, the third driving unit is started to drive the first movable plate and the second movable plate to move relative to each other, so that the clamping wheel gradually clamps the two sides of the transformer silicon steel sheet, and then, the second driving unit is started to drive the base to approach the end of the transformer silicon steel sheet until the end of the transformer silicon steel sheet is placed on the second push plate of the first rotating rod or the second rotating rod, then, the first driving unit is started to adjust the angle of the first rotating rod or the second rotating rod to be consistent with the inclination angle of the end of the transformer silicon steel sheet, and then the cylinder is started to drive the first push plate on the first rotating rod or the second rotating rod to move upward, so that the protrusions of the first push plate and the second push plate limit the end of the transformer silicon steel sheet, and then, the second driving unit can be started again, and the transformer silicon steel sheet can be pushed to the specified position by using the first push plate and the second push plate in contact with the end of the transformer silicon steel sheet, and finally, the positioned silicon steel sheet on the carrying platform can be grabbed and transported by an external grasping device to enter the stacking program.

[0096] The positioning device for stacking transformer silicon steel sheets proposed by the present invention realizes clamping of both sides of the transformer silicon steel sheets by setting a plurality of clamping assemblies, using the first movable plate and the second movable plate in each of the plurality of clamping assemblies which are relatively arranged at the lower end of the first through slot and can move relatively or towards each other along the first through slot, and the first movable plate and the second movable plate both have clamping wheels which can rotate in the circumferential direction. Then, through the base which is arranged at the lower end of the second through slot and can move along the second through slot and the guiding assembly arranged on the base, the first rotating rod and the second rotating rod which are cross-rotatingly connected in the guiding assembly, and the first push plate which is arranged on the first rotating rod and the second rotating rod and is configured to be independently lifted and lowered relative to the base, can realize the guiding of the ends of the transformer silicon steel sheets.

[0097] Furthermore, by arranging the second push plate on the first rotating rod and the second rotating rod, and making the first push plate and the second push plate both have bosses capable of limiting the position of the transformer silicon steel sheets, the ends of the transformer silicon steel sheets can be accurately guided.

[0098] In summary, compared with the existing positioning device of transformer silicon steel sheet, the positioning device of the present invention, on the one hand, can be compatible with the angle range of the end of the transformer silicon steel sheet of five shapes by the first rotating rod and the second rotating rod connected in a cross rotation, and the lifting and lowering transformation of the first push plate arranged on the first rotating rod and the second rotating rod, without the need to manually replace and adjust the guiding mechanism, and can adjust the position of the transformer silicon steel sheet by adjusting the position of the base, so as to meet the positioning of the transformer silicon steel sheet of five shapes, and expand the scope of application of the positioning device, on the other hand, by setting the clamping wheel to be able to rotate circumferentially, so that when the clamping wheel clamps the transformer silicon steel sheet, it is in a rotating state, reducing the friction between the clamping wheel and the transformer silicon steel sheet, so as to avoid the problem of the transformer silicon steel sheet being stuck or deformed during the adjustment process. In addition, the positioning device of the present invention is small in size and highly practical, and can achieve efficient positioning of the transformer silicon steel sheet under the cooperation of the clamping mechanism and the guiding mechanism, thereby improving the stacking efficiency of the transformer silicon steel sheet.

[0100] An electric control box (not shown) for supplying power to and controlling the first drive unit 21 , the second drive unit 16 and the third drive unit 11 .

[0101] In a specific embodiment, the first drive unit 21, the second drive unit 16 and the third drive unit 11 are all motors.

[0102] In a specific embodiment, the stacking device further includes a plurality of middle column pieces 29, a plurality of upper jaw pieces 30, a plurality of lower jaw pieces 31, a plurality of left pieces 32, and a plurality of right pieces 33, such as Figure 6 shown.

[0103] Although one or more embodiments of the present invention are described above, it should be known to those skilled in the art that the present invention can be implemented in any other form without departing from its subject matter and scope. Therefore, the embodiments described above are illustrative rather than restrictive, and many modifications and substitutions are obvious to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
