Description

Technical Field

[0001] The invention relates to the technical field of transformer core assembly, and in particular to a transformer core positioning and assembly device. Background Art

[0002] The transformer consists of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. It can transform AC voltage, current and impedance.

[0003] At present, the iron core of the transformer usually needs to be assembled with silicon steel sheets on the outside. When assembling the silicon steel sheets, they need to be stacked neatly layer by layer manually. The number of stacked silicon steel sheets is large, which is particularly time-consuming and labor-intensive. In addition, before stacking and assembling each silicon steel sheet, the surface needs to be manually coated with insulating oil. This process is also very time-consuming, which makes the assembly efficiency of the transformer core very low.

[0021] 3. By setting up a lifting mechanism and a pumping mechanism, when the silicon steel sheets are moved for stacking, the sliding plug will squeeze the air in the pumping cavity into the cavity through the one-way air outlet pipe, and the air will blow the fan blades to rotate, thereby driving the reciprocating screw to rotate, so that the slider moves upward first, driving the top plate to move upward, and pushing the silicon steel sheet under the transformer core upward for a distance. When the next silicon steel sheet partially moves under the silicon steel sheet, the slider will drive the top plate to move downward and reset. When the next silicon steel sheet is stacked in place, the top plate will also just reset, so that each time the silicon steel sheets are stacked, the previous silicon steel sheet will be pushed upward to avoid the silicon steel sheets from resisting each other, thereby preventing effective stacking.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0034] Reference Figure 1 - Fig.10 , a transformer core positioning and assembly device, comprising a processing table 1, a transformer core 2 and a silicon steel sheet 3;

[0035] The assembly mechanism includes two feeding boxes 4 symmetrically fixedly connected to the upper end of the processing table 1 through a bracket, two guide rails 5 are symmetrically fixedly connected between the two feeding boxes 4, a limiting groove 6 is provided on the upper end of the processing table 1, a vertical rod 7 is slidably connected to the inner wall of the limiting groove 6, a feeding plate 8 is fixedly connected to the upper end of the vertical rod 7, a rotating shaft 9 is rotatably connected to the upper end of the processing table 1, a cross rod 10 is fixedly connected to the side wall of the rotating shaft 9, a connecting rod 11 is fixedly connected to the side wall of the vertical rod 7, a sliding groove 12 is provided on the upper end of the connecting rod 11, the sliding groove 12 passes through the connecting rod 11, a driving rod 13 is fixedly connected to the upper end of the cross rod 10, and the side wall of the driving rod 13 is slidably connected to the inner wall of the sliding groove 12, a motor 14 is fixedly connected to the lower end of the processing table 1, and an output end of the motor 14 passes through the lower end of the processing table 1 and is fixedly connected to the rotating shaft 9.

[0036] The assembly mechanism also includes two first rotating rods 15 (such as Fig. 9 As shown), the side walls of the two first rotating rods 15 are fixedly connected with a push plate 16, and the side walls of the first rotating rods 15 are symmetrically sleeved with two torsion springs 17, and the two ends of the two torsion springs 17 are respectively fixedly connected to the side walls of the loading plate 8 and the inner walls of the push plate 16, and the side walls of the loading plate 8 are symmetrically fixedly connected with two limit plates 18 that cooperate with the push plate 16.

[0037] It should be noted that when the push plate 16 is reset, it will abut against the silicon steel sheet 3 in the loading box 4. Then the push plate 16 will rotate in the direction away from the limit plate 18, so as to facilitate the reset of the push plate 16. When the push plate 16 is completely reset, the push plate 16 will be reset to a vertical state under the action of the torsion spring 17, and the push plate 16 will abut against the limit plate 18 when pushing materials, so that the push plate 16 cannot rotate in the opposite direction, and the materials can be pushed successfully. In addition, the length of the push plate 16 entering the loading box 4 is less than the thickness of a silicon steel sheet 3, so two silicon steel sheets 3 will not be pushed at one time.

[0038] Furthermore, the driving motor 14 rotates, driving the cross bar 10 to rotate, and then driving the driving rod 13 to rotate. The driving rod 13 slides against the inner wall of the slide groove 12, and then slides on the inner wall of the slide groove 12, thereby driving the connecting rod 11 to move back and forth, driving the loading plate 8 to move back and forth, and then driving the pushing plates 16 on both sides to move back and forth, pushing the silicon steel sheets 3 in the loading box 4 to move, so that the silicon steel sheets 3 move to the transformer core 2, so that they are snapped into the transformer core 2, and the silicon steel sheets 3 are continuously stacked, and there is no need for manual stacking and assembly of the silicon steel sheets 3, which saves time and effort and has high assembly efficiency.

[0039] The guide rail 5 is provided with an oiling mechanism, which includes four L-shaped frames 26 symmetrically fixedly connected to the side walls of the guide rail 5, wherein two L-shaped frames 26 located on the same side are symmetrically connected to the side walls close to each other by two second rotating rods 27 (such as Fig.10 As shown), the side walls of the two second rotating rods 27 close to each other are fixedly connected with a rotating roller 28, and the side wall of the rotating roller 28 is fixedly connected with a plurality of bristles 281. An oil inlet cavity 29 is opened in the rotating roller 28, and a plurality of oil outlet holes 30 are opened on the inner wall of the oil inlet cavity 29.

[0040] The oiling mechanism also includes a rack 32 fixedly connected to the side wall of the loading plate 8 through a bracket, one end of a second rotating rod 27 passes through the side wall of the L-shaped frame 26 and is fixedly connected to a gear 31, and the gear 31 is meshed with the rack 32.

[0041] The processing table 1 is provided with an oil pump mechanism, which includes two slide cylinders 33 symmetrically fixedly connected to the side wall of the processing table 1 through a bracket, and the inner walls of the two slide cylinders 33 are both sealed and slidably connected with a slide plug 34 (such as Figure 8 As shown in the figure, the sliding plug 34 divides the interior of the slide cylinder 33 into two parts: a pump oil chamber 341 and a pump air chamber 342. The side wall of the loading plate 8 is symmetrically fixedly connected to two fixing rods 45. The two fixing rods 45 respectively penetrate the side walls of the two slide cylinders 33 and are fixedly connected to the sliding plug 34.

[0042] The oil pumping mechanism also includes a one-way oil inlet pipe 35 fixedly connected to the inner wall of the oil pumping chamber 341. The one-way oil inlet pipe 35 is connected to an external container storing insulating oil, and the one-way oil inlet pipe 35 only allows external insulating oil to enter the oil pumping chamber 341. The side wall of the L-shaped frame 26 is fixedly connected with a rotating joint 37 through a bracket. One end of the second rotating rod 27 is fixedly connected to the rotating joint 37. An oil inlet groove 38 is opened in the second rotating rod 27. One end of the oil inlet groove 38 is connected to the oil inlet chamber 29. A one-way oil outlet pipe 36 is fixedly connected to the inner wall of the oil pumping chamber 341. The other end of the one-way oil outlet pipe 36 is fixedly connected to the rotating joint 37. The one-way oil outlet pipe 36 only allows the insulating oil in the oil pumping chamber 341 to enter the oil inlet groove 38.

[0043] Furthermore, when the silicon steel sheets 3 are stacked and assembled, when the push plate 16 pushes the silicon steel sheets 3 to move toward the transformer core 2, the loading plate 8 will synchronously drive the fixed rod 45 to move, and then drive the sliding plug 34 to slide in a sealed manner. At this time, the sliding plug 34 will squeeze the insulating oil in the pump oil chamber 341 into the oil inlet groove 38 through the one-way oil outlet pipe 36, and then the insulating oil will enter the oil inlet chamber 29. Finally, the insulating oil will be sprayed out through multiple oil outlet holes 30 and sprayed onto the surface of the silicon steel sheets 3. While the loading plate 8 moves, it will drive the rack 32 to move, and then drive the gear 31 to rotate, drive the second rotating rod 27 to rotate, thereby driving the rotating roller 28 to rotate, and drive multiple bristles 281 to rotate, so that the insulating oil on the surface of the silicon steel sheet 3 is evenly applied, without the need for manual application of insulating oil, reducing the process, and thus further improving the assembly efficiency of the transformer core 2.

[0044] It should be noted that, since the silicon steel sheets 3 in the loading boxes 4 on both sides are loaded and stacked alternately, the oil pumping and oil suction states in the slide cylinders 33 on both sides are also opposite. When one slide cylinder 33 is pumping oil, the other side is sucking oil.

[0045] A lifting mechanism is installed on the processing table 1, and the lifting mechanism includes a limit rod 19 fixedly connected to the upper end of the processing table 1, a slider 20 is slidably connected to the side wall of the limit rod 19, and a top plate 21 is fixedly connected to the upper end of the slider 20 through a fixed shaft.

[0046] The lifting mechanism also includes a reciprocating screw 22 rotatably connected to the upper end of the processing table 1, the side wall of the reciprocating screw 22 is threadedly connected to the slider 20, a cavity 23 is opened in the processing table 1, the lower end of the reciprocating screw 22 extends into the cavity 23 and is fixedly connected to a plurality of fan blades 24, an exhaust hole 25 is opened on the inner wall of the cavity 23, a one-way air inlet pipe 39 is fixedly connected to the inner wall of the pump air cavity 342, and the pump air cavity 342 is connected to the cavity 23 through a one-way air outlet pipe 40.

[0047] It should be noted that the diameter of the one-way air outlet pipe 40 at the connection point with the cavity 23 is much smaller than the diameter of the one-way air outlet pipe 40 at the connection point with the slide cylinder 33, so that the wind speed entering the cavity 23 through the one-way air outlet pipe 40 is faster, thereby increasing the driving force of the wind blowing the fan blades 24. Even if too many silicon steel sheets 3 are stacked, the reciprocating screw 22 can still rotate normally.

[0048] It should be noted that when the next silicon steel sheet 3 partially moves to the bottom of the silicon steel sheet 3 already installed in the transformer core 2, the slider 20 will drive the top plate 21 to move downward and reset, so that the top plate 21 will not interfere with the stacking of the silicon steel sheets 3. When the next silicon steel sheet 3 is stacked in place, the top plate 21 is also reset.

[0049] Furthermore, when the silicon steel sheets 3 are moved for stacking, the sliding plug 34 will squeeze the air in the pump air cavity 342 into the cavity 23 through the one-way air outlet pipe 40, and the air will blow the fan blades 24 to rotate, thereby driving the reciprocating screw 22 to rotate, so that the slider 20 moves upward first, driving the top plate 21 to move upward, and pushing the silicon steel sheets 3 under the transformer core 2 upward for a distance. When the next silicon steel sheet 3 partially moves below the silicon steel sheet 3, the slider 20 will drive the top plate 21 to move downward and reset. When the next silicon steel sheet 3 is stacked in place, the top plate 21 is also reset, so that each time the silicon steel sheets 3 are stacked, the previous silicon steel sheet 3 will be pushed upward to avoid the silicon steel sheets 3 from resisting each other, thereby preventing effective stacking.

[0050] Two baffles 41 are symmetrically fixedly connected to the side wall of the loading box 4. The baffles 41 can block the silicon steel sheets 3 in the loading box 4 to prevent the silicon steel sheets 3 on the upper layer from moving due to the friction between the silicon steel sheets 3 when the silicon steel sheets 3 on the bottom layer move to load.

[0051] The two side walls of the two guide rails 5 are symmetrically fixedly connected with two fixing plates 42, and the side walls of the two fixing plates 42 are fixedly connected with electric push rods 43. The movable ends of the electric push rods 43 pass through the side walls of the fixing plates 42 and are fixedly connected with clamping plates 44. The side walls of the guide rails 5 are symmetrically fixedly connected with two blocking pieces 46.

[0052] It should be noted that the distance between the inner top of the baffle 46 and the upper end of the guide rail 5 is the thickness of a silicon steel sheet 3, so that when the silicon steel sheet 3 is inserted into the bottom layer, the baffle 46 can be against the upper silicon steel sheet 3, thereby preventing the upper silicon steel sheet 3 from moving out of the transformer core 2 due to the friction force when the silicon steel sheet 3 is inserted, causing the assembly position of the silicon steel sheet 3 to be offset.

[0053] In the present invention, the transformer core 2 is first placed in the center position of the upper end of the guide rail 5, and then the electric push rod 43 is driven to extend, driving the clamping plate 44 to clamp and fix the transformer core 2, and then the silicon steel sheets 3 are placed in the loading box 4, and then the driving motor 14 is driven to rotate, driving the cross bar 10 to rotate, and then driving the driving rod 13 to rotate, and the driving rod 13 slides against the inner wall of the slide groove 12, and will slide on the inner wall of the slide groove 12, and then drive the connecting rod 11 to move back and forth, drive the loading plate 8 to move back and forth, and then drive the pushing plates 16 on both sides to move back and forth, push the silicon steel sheets 3 in the loading box 4 to move, so that the silicon steel sheets 3 move to the transformer core 2, so that they are clamped into the transformer core 2, and the silicon steel sheets 3 are continuously stacked, and there is no need to manually stack and assemble the silicon steel sheets 3, which saves time and effort and has high assembly efficiency.

[0054] When the silicon steel sheets 3 are stacked and assembled, when the push plate 16 pushes the silicon steel sheets 3 to move toward the transformer core 2, the loading plate 8 will synchronously drive the fixing rod 45 to move, thereby driving the sliding plug 34 to slide in a sealed manner. At this time, the sliding plug 34 will squeeze the insulating oil in the pump oil chamber 341 into the oil inlet groove 38 through the one-way oil outlet pipe 36, and then the insulating oil will enter the oil inlet chamber 29. Finally, the insulating oil will be sprayed out through multiple oil outlet holes 30 and sprayed onto the surface of the silicon steel sheets 3. When the loading plate 8 moves, it will drive the rack 32 to move, thereby driving the gear 31 rotates, driving the second rotating rod 27 to rotate, thereby driving the rotating roller 28 to rotate, and driving the multiple bristles 281 to rotate, so that the insulating oil on the surface of the silicon steel sheet 3 is evenly applied, without the need for manual application of the insulating oil, reducing the process, thereby further improving the assembly efficiency of the transformer core 2, and when the feeding plate 8 is reset, the sliding plug 34 will slide and reset, and then the external insulating oil will be drawn into the slide cylinder 33 through the one-way oil inlet pipe 35 for storage. Since the silicon steel sheets 3 on both sides are stacked alternately, the oil pumping and oil suction states in the slide cylinders 33 on both sides are opposite.

[0055] In addition, when the silicon steel sheets 3 are moved for stacking, the sliding plug 34 will squeeze the air in the pump air cavity 342 into the cavity 23 through the one-way air outlet pipe 40. The air will blow the fan blades 24 to rotate, and then drive the reciprocating screw 22 to rotate, so that the slider 20 moves upward first, driving the top plate 21 to move upward, and pushing the silicon steel sheets 3 under the transformer core 2 upward for a distance. When the next silicon steel sheet 3 partially moves below the silicon steel sheet 3, the slider 20 will drive the top plate 21 to move downward and reset. When the next silicon steel sheet 3 is stacked in place, the top plate 21 is also reset, so that each time the silicon steel sheets 3 are stacked, the previous silicon steel sheet 3 will be pushed upward to avoid the silicon steel sheets 3 from resisting each other, thereby preventing effective stacking.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
