Description

Technical Field

[0001] The utility model belongs to the technical field of silicon steel sheet stacking, and more specifically relates to a positioning device and stacking equipment for silicon steel sheet stacking. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Silicon steel sheets are the primary component of the iron core. They are processed into five shapes: upper jaw sheets, lower jaw sheets, left sheets, right sheets, and center 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 pattern. Before stacking these five shapes of silicon steel sheets, they need to be clamped on both sides, then the ends of the silicon steel sheets need to be aligned using a guiding mechanism, and the position of the silicon steel sheets needs to be adjusted so that after being grasped by external grasping equipment, the silicon steel sheets can be stacked in an offset manner for subsequent use.

[0003] However, the existing positioning device for silicon steel sheets is difficult to be compatible with five shapes of silicon steel sheets and can only support the correction of the ends of silicon steel sheets of one shape. The existence of this structural defect limits the scope of use of the existing positioning device for silicon steel sheets, resulting in a decrease in the stacking efficiency of silicon steel sheets. In addition, if the correction of the ends of silicon steel sheets of five shapes is to be required, it is necessary to manually replace the correction mechanism or integrate positioning devices that are compatible with the ends of silicon steel sheets of each shape. However, the volume of the integrated positioning device is increased, and in actual application, it will take up a large space, be difficult to carry, and be costly, making it difficult to implement.

[0004] Therefore, the existing positioning device is still not conducive to the stacking and use of silicon steel sheets, and needs further improvement. Utility Model Content

[0060] Reference Figures 1 - 6 The embodiment of the present utility model provides a positioning device for stacking silicon steel sheets, comprising:

[0061] A carrying platform 1 is provided with a first through slot 2 and a second through slot 3;

[0062] The first positioning mechanism includes a plurality of clamping assemblies, each of which includes a first movable plate 4 and a second movable plate 5 relatively arranged at the lower end of the first through slot 2 and capable of moving relative to or toward each other along the first through slot 2. The first movable plate 4 and the second movable plate 6 are both provided with a clamping wheel 6, which is configured to be able to rotate circumferentially, and its upper end passes through and exceeds the first through slot 2, and is used to clamp both sides of the silicon steel sheet;

[0063] The second positioning mechanism includes a base 7 which is arranged at the lower end of the second through slot 3 and can move along the second through slot 3. A first guide plate 8 is provided on the base 7, the upper end of which passes through and exceeds the second through slot 3. A second guide plate 9 and a third guide plate 10 are relatively provided on both sides of the first guide plate 8. The second guide plate 9 and the third guide plate 10 are both configured to be able to be independently lifted and lowered relative to the base 7. The three guide plates are all used to guide the ends of the silicon steel sheets.

[0064] In a specific embodiment, the side of the carrying platform 1 used for carrying the silicon steel sheet is coated with a coating. The coating is used to reduce the friction between the silicon steel sheet and the carrying platform, improve the surface smoothness of the carrying platform, and facilitate the positioning operation of the silicon steel sheet.

[0065] In a specific embodiment, the material of the carrying platform 1 is aluminum.

[0066] In a specific embodiment, the first positioning mechanism includes five clamping assemblies evenly distributed along the extension direction of the carrying platform 1. Of course, it should be appreciated that the clamping assemblies in the present invention can be provided in other numbers, and the present invention is not limited thereto. Any number of clamping assemblies that can achieve the same technical effect of the present invention is within the scope of protection of the present invention.

[0067] In one embodiment, each clamping assembly further includes a second 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 .

[0068] In a specific embodiment, the first positioning mechanism further includes a second driving unit 11 for driving the second driving component.

[0069] In a specific embodiment, the second driving component includes a second lead screw 12 and a second guide rail 13. One end of the second lead screw 12 is connected to the transmission end of the second driving unit 11, and the other end thereof is threadedly connected to the first movable plate 4 and the second movable plate 5. The second guide rail 13 is disposed on the bearing platform 1 for guiding the movement of the first movable plate 4 and the second movable plate 5.

[0070] In a specific embodiment, the first positioning mechanism further includes a plurality of synchronous belts 14. Each of the plurality of synchronous belts 14 is respectively used to connect adjacent two second lead screws 12 and adjacent second lead screws 12 and the second driving unit 11, so as to connect the second lead screws 12 in each clamping and straightening assembly to the transmission end of the second driving unit 11.

[0071] In a specific embodiment, two fixed shafts 15 are symmetrically disposed on the first movable plate 4 and the second movable plate 5, and the clamping wheels 6 are sleeved on the fixed shafts 15.

[0072] In a specific embodiment, the first through groove 2 is provided in one-to-one correspondence with the clamping wheels 6.

[0073] Specifically, the clamping wheels can move relatively under the drive of the first movable plate and the second movable plate. When contacting the silicon steel sheet, the clamping wheels are in a rotating state, and the friction force between them and the silicon steel sheet is small. During the process of gradually clamping and straightening the silicon steel sheet, the problem of jamming or deformation of the silicon steel sheet can be avoided, which is convenient for clamping or releasing the silicon steel sheet. In addition, the clamping and straightening mechanism can also meet the requirement of clamping both sides of the silicon steel sheet with a width of 40 - 440 mm and a length of 400 - 2000 mm, so as to improve the utilization rate of the positioning device.

[0074] In an embodiment, the second positioning mechanism further includes a first driving component for driving the base 7 to move along the second through groove 3.

[0075] In a specific embodiment, the first driving component includes a first driving unit 16, a first lead screw 17 and a first guide rail 18. One end of the first lead screw 17 is connected to the transmission end of the first driving unit 16, and the other end thereof is threadedly connected to the base 7. The first guide rail 18 is connected to the bearing platform 1 for guiding the movement of the base 7.

[0076] Specifically, since the silicon steel sheets need to be offset by a certain distance during stacking, the first guide rail has a first track and a second track disposed on both sides of the second chute. When the first driving unit drives the first lead screw, the base can move along the second chute through the interaction with the first lead screw and the guidance of the first track and the second track, so as to adjust the distance between the base and the silicon steel sheets. At the same time, the position of the silicon steel sheets can be adjusted, so that after the external grasping device grasps the silicon steel sheets, the silicon steel sheets can be stacked in a staggered manner, which is convenient for subsequent use.

[0077] In one embodiment, a first lifting assembly and a second lifting assembly are disposed in the base 7 and are respectively used to drive the second guiding plate 9 and the third guiding plate 10 to lift independently.

[0078] In a specific embodiment, both the first lifting assembly and the second lifting assembly include a connecting plate 19 and a cylinder 20 for driving the connecting plate 19 to lift, and the connecting plates 19 of the two are respectively connected to the second guiding plate 9 and the third guiding plate 10.

[0079] When it is necessary to align the end of any one of the five types of silicon steel sheets, the second guiding plate and / or the third guiding plate can be pushed up or down through the cylinder connected thereto to achieve the alignment of the end of the silicon steel sheet. Specifically, the following three implementation manners are included:

[0080] In the first implementation manner, only the second guiding plate 9 moves upward, then the second guiding plate 9 and the first guiding plate 8 are jointly used to align the ends of the other silicon steel sheets except the middle column sheet 21.

[0081] In the second implementation manner, only the third guiding plate 10 moves upward, then the third guiding plate 10 and the first guiding plate 8 are jointly used to align the ends of the other silicon steel sheets except the middle column sheet 21.

[0082] In the third implementation manner, the second guiding plate 9 and the third guiding plate 10 move upward simultaneously to align the end of the middle column sheet 19.

[0083] Specifically, the ends of the upper jaw piece, the lower jaw piece, the left side piece, and the right side piece all have angles that can face the second guiding plate and / or the third guiding plate. Therefore, when only the second guiding plate or the third guiding plate moves upward, the requirement of aligning the ends of the other silicon steel sheets except the middle column sheet can be satisfied simultaneously, making the second positioning mechanism more flexible and capable of satisfying the precise alignment of the ends of the five-shaped silicon steel sheets.

[0084] When the positioning device of the present utility model is in use, first, the silicon steel sheet to be positioned needs to be placed on the bearing platform through an external feeding device. Then, the second driving unit is started to drive the first movable plate and the second movable plate to move relatively, so that the clamping wheels gradually clamp both sides of the silicon steel sheet. Then, the first driving unit is started to drive the base close to the end of the silicon steel sheet, and according to the inclination direction of the end of the silicon steel sheet, the air cylinder is started to drive the second guiding plate or the third guiding plate to move upward, so that the second guiding plate or the third guiding plate cooperates with the first guiding plate to guide the end of the silicon steel sheet. Then, the first driving unit can be started again to push the silicon steel sheet to the designated position by using the second guiding plate or the third guiding plate and the first guiding plate. Finally, the positioned silicon steel sheet on the bearing platform can be grabbed and transported by an external grabbing device to enter the stacking process.

[0085] The positioning device for silicon steel sheet stacking proposed by the present utility model realizes the clamping of both sides of the silicon steel sheet by arranging a plurality of clamping components, using the first movable plate and the second movable plate that are oppositely arranged at the lower end of the first through groove and can move relatively or in opposite directions in each clamping component, and the clamping wheels arranged on both the first movable plate and the second movable plate and configured to be able to rotate circumferentially, with their upper ends penetrating and exceeding the first through groove. Then, by arranging the base at the lower end of the second through groove and capable of moving along the second through groove, using the first guiding plate arranged on the base with its upper end penetrating and exceeding the second through groove, and the second guiding plate and the third guiding plate that are oppositely arranged on both sides of the first guiding plate and are both configured to be able to independently lift relative to the base, the three guiding plates can be changed according to the shape of the end of the silicon steel sheet to realize the guiding of the end of the silicon steel sheet.

[0086] Therefore, compared with the existing positioning devices, the positioning device of the present utility model can be compatible with silicon steel sheets of five shapes, realize the positioning of silicon steel sheets of five shapes. In addition, by setting the clamping wheels to be able to rotate circumferentially, when the clamping wheels clamp the silicon steel sheet, they are in a rotating state, reducing the friction between the clamping wheels and the silicon steel sheet, thereby being able to avoid the problems of jamming or deformation of the silicon steel sheet during the adjustment process, being conducive to the stacking and use of the silicon steel sheet, and thus improving the stacking efficiency of the silicon steel sheet.

[0087] Correspondingly, the present utility model also provides a stacking device, including the positioning device for silicon steel sheet stacking in any of the above embodiments. The stacking device further includes:

[0088] An electric control box (not shown in the figure) for supplying power and controlling the first driving unit 16 and the second driving unit 11.

[0089] In a specific embodiment, both the first driving unit 16 and the second driving unit 11 are motors.

[0090] In a specific embodiment, the stacking device further includes a plurality of middle column pieces 21, a plurality of upper jaw pieces 22, a plurality of lower jaw pieces 23, a plurality of left side pieces 24, and a plurality of right side pieces 25, as Figure 6 shown.

[0091] Although one or more embodiments of the present invention have been described above, those of ordinary skill in the art should understand that the present invention can be implemented in any other form without departing from its gist and scope. Therefore, the above-described embodiments are illustrative rather than restrictive, and many modifications and substitutions will be obvious to those of ordinary skill in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
