Description

Technical Field

[0001] The present invention relates to the technical field of transformer production, and in particular to a semi-automatic transformer lamination system and method. Background Art

[0002] The iron core of the transformer is formed by stacking silicon steel sheets. The iron core of the UI type transformer is formed by a U-shaped lamination group and an I-shaped lamination group. The U-shaped lamination group is composed of iron sheets with different side column heights stacked together, and a gap is formed between two adjacent higher side columns, so that multiple gaps are formed at the top of the convex column of the U-shaped lamination group. The I-type lamination group is formed by the staggered stacking of iron sheets of the same size, and gaps are also formed at both ends of the I-type lamination group, so that the end of the I-type lamination group is inserted into the top of the convex column of the U-shaped lamination group to complete the installation of the iron core.

[0003] In the iron core assembly process, firstly, the coil is wound on the convex column of the U-shaped lamination group, and then the iron core sheets of the same size are inserted into the gap between the two convex columns of the U-shaped lamination group one by one, and the tail ends of the iron core sheets of the same size are stacked to form an I-type lamination group; another assembly method of the I-type lamination group is: firstly, a predetermined number of iron core sheets are manually taken, and then the iron core sheets are stacked one by one to complete the lamination, and after the lamination is completed, the two ends of the I-type lamination group are respectively inserted into the gap between the two convex columns of the U-shaped lamination group. Both of these assembly methods consume a lot of manpower to assemble the I-type lamination group and the U-type lamination group, affecting the assembly efficiency. After the convex column of the U-shaped lamination group is wound with the coil, the gap at the top of the convex column is easily deformed, which makes it difficult to insert the end of the I-type lamination group into the top of the convex column, and also affects the assembly efficiency.

DETAILED DESCRIPTION

[0041] The following will disclose the embodiments of the present invention with the aid of the accompanying drawings. For the sake of clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures will be shown in a simple schematic manner in the drawings. Figures 1 to 10 , a semi-automatic transformer lamination insertion system according to an embodiment of the present invention is described.

[0042] A semi-automatic transformer lamination insertion system of the present invention includes a slicing mechanism and a comb. The slicing mechanism includes a rectangular groove body 10 and a plurality of slicing grooves 20 arranged side by side. One end of the slicing groove 20 is located inside the rectangular groove body 10, and the notch of the slicing groove 20 faces the other end of the rectangular groove body 10; the distance L3 between the notch of the slicing groove 20 and the inner wall of the end of the rectangular groove body 10 is greater than or equal to the length L2 of the iron core sheet 1; the relationship between the groove width H of the slicing groove 20 and the thickness D of the iron core sheet 1 is: D < H < 2D; the relationship between the groove width H and the groove wall thickness T of the slicing groove 20 and the thickness D of the iron core sheet 1 is 2D < H + T < 3D. The comb includes a U-shaped groove body 01, and a plurality of second comb teeth 02 are arranged side by side inside the U-shaped groove body 01. The plurality of second comb teeth 02 are spaced apart, and a comb gap 03 is formed between two adjacent second comb teeth 02; the depth of the comb gap 03 is greater than the width of the iron core sheet, and the relationship between the width A of the comb gap 03 and the thickness D of the iron core sheet 1 is: D ≤ A < 2D.

[0043] Among them, the process of the slicing mechanism performing the slicing operation is as follows: The rectangular groove body 10 is in a horizontal state with the notch facing upward, a specified number of iron core sheets are placed into the rectangular groove body 10, and then the rectangular groove body 10 is rotated to a vertical state. Under the action of gravity, the ends of some iron core sheets are inserted into the slicing grooves 20, and the other part of the iron core sheets are restricted by the groove walls of the slicing grooves 20, and the specified number of iron core sheets in the rectangular groove body 10 are misaligned, realizing the rapid slicing of the I-shaped lamination group. The distance L3 between the notch of the slicing groove 20 and the end of the rectangular groove body 10 is greater than or equal to the length L2 of the iron core sheet, which can quickly place the specified number of un-sliced iron core sheets into the rectangular groove body 10. Based on the relationship between the groove width H of the slicing groove 20 and the thickness D of the iron core sheet: D < H < 2D, it is ensured that only one iron core sheet can enter the slicing groove 20. At the same time, it is required that the relationship between the groove width H and the groove wall thickness T of the slicing groove 20 and the thickness D of the iron core sheet is 2D < H + T < 3D, forming a slicing effect with adjacent iron core sheets misaligned. The length L1 inside the rectangular groove body is greater than the length of the iron core sheet.

[0044] The distance L3 between the slot opening of the slicing slot 20 and the end of the rectangular slot body 10 is slightly greater than the length L2 of the iron core piece, and preferably L3 is 2-3 mm longer than L2. While facilitating the placement of the iron core piece into the rectangular slot body 10, the iron core piece will not have too much room for movement in the rectangular slot body 10, thereby ensuring the accuracy of slicing. It should be noted that in actual production, the sizes of the iron core pieces will be different due to the different specifications of the UI transformers. In order to make the iron core slicing mechanism of the present invention applicable to transformers of various models, a pad 60 is placed on the side of the enlarged rectangular slot body 10 and / or on one end away from the slicing slot 20, so that the space for placing the iron core piece in the rectangular slot body 10 corresponds to the size of the iron core piece.

[0045] After the lamination is completed, the I-type lamination group needs to be inserted into the top of the protrusion of the U-type lamination group, so that the height of the rectangular trough body 10 and the height of the lamination slot 20 are both smaller than the width of the iron core sheet, which can make the iron core sheet protrude outside the rectangular trough body 10. When assembling the I-type lamination group and the U-type lamination group, the I-type lamination group is directly inserted into the top of the protrusion of the U-type lamination group under the support of the rectangular trough body 10. The lamination slot 20 of the rectangular trough body 10 can maintain the end gap of the I-type lamination group, and the assembly operation is faster.

[0046] Furthermore, the length of the segmented slot 20 is 0.2-0.5 times the length of the rectangular slot 10. Preferably, the length of the segmented slot 20 corresponds to the staggered length of the core sheets of the I-type lamination stack, which is more conducive to the rapid assembly of the I-type lamination stack and the U-type lamination stack.

[0047] Specifically, a plurality of first gaskets 30 and a plurality of first combs 40 are fixed at one end of the rectangular trough body 10, and the first gasket 30 is located between two adjacent first combs 40; the gap between two adjacent first combs 40 forms a slicing slot 20, so that the structure of the iron core slicing mechanism is simple and easy to produce. It is worth noting that the height of the first gasket 30 corresponds to the height of the first comb 40, so that the first gasket 30 forms the bottom of the slicing slot 20, and when the rectangular trough body 10 is flipped to a vertical state, the first gasket 30 has a better supporting effect on the iron core sheet.

[0048] Based on the fact that the iron core sheets of different models of UI transformers have different thicknesses, further, multiple first gaskets 30 and multiple first comb sheets 40 can be removably installed in the rectangular trough body 10, so that the first gaskets 30 and the first comb sheets 40 can be replaced corresponding to iron core sheets of different thicknesses, so that the iron core splitting mechanism can split iron core sheets of different thicknesses.

[0049] In order to simplify the detachable installation structure of the first gasket 30 and the first comb piece 40, a first positioning rod 50 is passed through one end of the rectangular trough body 10, and the first positioning rod 50 is detachably connected to the rectangular trough body 10. A plurality of first gaskets 30 and a plurality of first comb pieces 40 are sleeved on the first positioning rod 50, so that the first gasket 30 and the first comb piece 40 can be replaced by removing the first positioning rod 50. Specifically, the first positioning rod 50 is a round rod or a rectangular rod, and the first gasket 30 and the first comb piece 40 are provided with a through hole that matches the shape of the first positioning rod 50. When the first positioning rod 50 is a round rod, the through holes on the first gasket 30 and the first comb piece 40 are round holes, and the number of the first positioning rods 50 is two, so that the first gasket 30 and the first comb piece 40 are stably fixed in the rectangular trough body 10, the tail end of the round rod has a thread and the front end has a nut, and the round rod passes through the rectangular trough body 10 and the nut is tightened at its tail end to fix the round rod. When the first positioning rod 50 is a rectangular rod, the through holes on the first gasket 30 and the first comb piece 40 are rectangular holes, and a first positioning rod 50 can achieve a good positioning effect. The tail end of the rectangular rod has a socket and the front end has a limiting cap. After the rectangular rod passes through the rectangular slot body 10, a pin body is inserted into the socket at its tail end to fix the rectangular rod.

[0050] When the rectangular trough body 10 is flipped to a vertical state, the iron core piece located in the slice groove 20 needs to be positioned, so a limiting member 70 is provided on the top of the rectangular trough body 10, and the limiting member 70 spans the rectangular trough body 10, and the limiting member is used to limit the iron core piece in the rectangular trough body 10. Specifically, the limiting member 70 includes a connecting ear 71 and a plug-in piece 72, and the tops of both sides of the rectangular trough body 10 are connected with connecting ears 71; the two connecting ears 71 are provided with plug-in holes 711 for inserting the plug-in pieces 72. The plug-in pieces 72 are inserted into the plug-in holes 711 of the two connecting ears 71, so as to limit the iron core piece across the rectangular trough body 10. Preferably, the limiting member 70 is located in the middle of the rectangular trough body 10; the plug-in piece 72 has a larger width to form a larger limiting surface, thereby improving the reliability of the limitation.

[0051] It is worth noting that in order to facilitate the production and assembly of the iron core segmentation mechanism, the rectangular trough body 10 includes a U-shaped main trough body, a baffle is installed at one end of the main trough body, and the segmentation groove 20 is located at the other end of the main trough body, forming an accommodating space for the iron core segmentation chip between the baffle and the segmentation groove 20.

[0052] It is worth noting that the core slicing mechanism of the present invention can be applied to automatic slicing equipment and can also be used for manual slicing. When the core slicing mechanism is used for manual slicing, a first handle 80 is installed at the bottom of the rectangular trough 10 to facilitate manual flipping of the rectangular trough 10. The core slicing mechanism also includes a vibrator 90, which includes a base 91 and a mounting trough 92. The vibrator 90 is installed in the base 91, and the mounting trough 92 is connected to the vibrator 90; the opening of the mounting trough 92 is upward, and the opening of the mounting trough 92 is adapted to the end of the rectangular trough 10. The first handle 80 is manually operated to insert the end of the rectangular trough 10 into the mounting trough 92, and the rectangular trough 10 is in a vertical state. The vibrator 90 in the base 91 is turned on, so that the end of a part of the iron core sheet is inserted into the slicing slot 20, and the other part of the iron core sheet is limited by the slot wall of the slicing slot 20. The prescribed number of iron core sheets in the rectangular trough 10 are dislocated to achieve rapid slicing of the I-type lamination group.

[0053] The combing device in the present invention is similar to a comb, and is used to insert into the gap at the top of the protrusion of the U-type lamination group when assembling the I-type lamination group and the U-type lamination group, and to shape the gap, so as to facilitate the insertion of the end of the I-type lamination group into the top of the protrusion of the U-type lamination group. Specifically, the second combing piece 02 is inserted into the gap at the top of the protrusion of the U-type lamination group, and the size relationship between the width A of the combing slot 03 and the thickness D of the iron core sheet is: D≤A<2D, so that each iron core sheet is located in a combing slot 03, so that the iron core sheets of the U-type lamination group are arranged at equal intervals, ensuring that the gap size at the top of the protrusion of the U-type lamination group is the same, which is convenient for assembly with the I-type lamination group and improves assembly efficiency.

[0054] Furthermore, the U-shaped trough body 01 is also fixed with a plurality of second gaskets 04, and a second gasket 04 is provided between each of two adjacent second combing pieces 02. The second gasket 04 is used to arrange the plurality of second combing pieces 02 at equal intervals. The arrangement of the second gasket 04 and the second combing piece 02 makes the shaping combing device for the transformer core simple in structure and has good strength. It is worth noting that the width of the second gasket 04 corresponds to the width of the second combing piece 02, so that the second gasket 04 forms the bottom of the combing slit 03, and the combing slit 03 is not easy to deform. When the combing device is inserted into the U-shaped lamination group, the combing slit 03 has a better shaping effect on the iron core.

[0055] Based on the different thicknesses of the iron core sheets of different models of UI transformers, further, the second comb piece 02 and the second gasket 04 can be removably installed in the U-shaped groove body 01, so that the second gasket 04 and the second comb piece 02 can be replaced corresponding to the iron core sheets of different thicknesses, so that the combing device can comb the iron core sheets of different thicknesses.

[0056] In order to simplify the detachable installation structure of the second gasket 04 and the second comb piece 02, a second positioning rod 05 is passed through the bottom end of the U-shaped groove body 01, and the second positioning rod 05 is detachably connected to the U-shaped groove body 01. Multiple second gaskets 04 and multiple second comb pieces 02 are all mounted on the second positioning rod 05. Therefore, the second gasket 04 and the second comb piece 02 can be replaced by removing the second positioning rod 05.

[0057] Specifically, the second positioning rod 05 is a screw rod or a rectangular rod, and the second gasket 04 and the second comb piece 02 are both provided with a through hole that matches the shape of the second positioning rod 05. When the second positioning rod 05 is a screw rod, the through hole on the second gasket 04 and the second comb piece 02 is a round hole, and the number of the second positioning rods 05 is two, so that the second gasket 04 and the second comb piece 02 are stably fixed in the rectangular trough body, the tail end of the screw rod has a thread and the front end has a nut, and after the screw rod passes through the U-shaped trough body 01, the round rod can be fixed by tightening the nut at its tail end. When the second positioning rod 05 is a rectangular rod, the through hole on the second gasket 04 and the second comb piece 02 is a rectangular hole, and a second positioning rod 05 can achieve a good positioning effect, the tail end of the rectangular rod has a socket and the front end has a limit cap, and after the rectangular rod passes through the U-shaped trough body 01, the rectangular rod can be fixed by inserting a pin into the socket at its tail end.

[0058] Furthermore, the width of the second comb piece 02 gradually decreases from the bottom end toward the top end, so that the second comb piece 02 is trapezoidal; the second gasket 04 is located at the bottom end of the second comb piece 02, which has a better positioning effect on the second comb piece 02 and is also convenient for the installation of the second gasket 04; the side wall width of the U-shaped groove body 01 corresponds to the width of the second comb piece 02. The shape of the shaping comber for the transformer core is generally narrow at the top and large at the bottom, so that the top end is inserted into the gap from point to surface, and the comber is more easily aligned with the gap at the top end of the convex column of the U-shaped lamination group.

[0059] Furthermore, both sides of the top of the second comb piece 02 have inclined surfaces to reduce the thickness of the top of the second comb piece 02. The smaller width and thickness of the top of the second comb piece 02 make it easier to insert into the gap at the top of the boss of the U-shaped stack.

[0060] In order to make the thickness of the second comb piece 02 and the width of the combing slit 03 slightly larger than the thickness of the iron core sheet, when the comber is inserted into the gap at the top of the convex column of the U-shaped lamination group, the iron core sheet will be slightly deformed. In order to further facilitate the insertion of the comber into the iron core sheet, the gap width between the side wall of the U-shaped trough body 01 and the adjacent second comb piece 02 is larger than the width A of the combing slit 03, so as to reserve space for the deformation of the iron core sheet. Preferably, the width of the U-shaped trough body 01 is 110-120mm, the width of the combing slit 03 is 0.5-1mm, and the gap width between the side wall of the U-shaped trough body 01 and the adjacent second comb piece 02 is 3mm.

[0061] The shaping comber for transformer core of the present invention can be applied to automatic combing equipment or manual combing. When the comber is used for manual lamination, a second handle 06 is installed at the bottom of the U-shaped trough 01 to facilitate manual insertion of the comber into the gap at the top of the boss of the U-shaped lamination stack.

[0062] Accordingly, the present invention further provides a method for semi-automatic stacking of transformer sheets, characterized in that the method is applied to the above-mentioned semi-automatic stacking system of transformer sheets, and the method comprises the following steps:

[0063] A specified number of core sheets are placed in the rectangular trough body, and then the rectangular trough body is rotated to a vertical state. Under the action of gravity, the ends of some core sheets are inserted into the slicing grooves, and the other core sheets are restricted by the groove walls of the slicing grooves. The specified number of core sheets in the rectangular trough body are displaced, and the slicing is completed to obtain an I-type lamination group;

[0064] Insert the comb into the gap at the top of the boss of the U-shaped stack to shape the gap;

[0065] The I-type lamination group is inserted into the top of the protrusion of the U-type lamination group under the carrier, or the top of the protrusion of the U-type lamination group with a comber is inserted into the end of the I-type lamination group in the rectangular slot.

[0066] Other structures and operations of a system and method for semi-automatic stacking of transformers according to the embodiments of the present invention are well known to those skilled in the art and will not be described in detail here.
