Description

Technical Field

[0001] This invention belongs to the field of transformer assembly technology, and specifically discloses a mechanized assembly structure for transformers. Background Technology

[0002] During the transformer assembly process, the use of a mechanized inserter to drive the silicon steel sheets into the coil frame not only significantly improves the transformer assembly efficiency, but also helps to accurately control the number of silicon steel sheets inserted, thus ensuring the stability of the overall transformer performance.

[0003] Currently, the equipment available on the market for inserting silicon steel sheets into coil bobbins mainly includes a clamping structure and inserting structures that are relatively distributed on both sides of the clamping structure. In actual use, the clamping structure clamps the coil bobbin, and the relatively distributed inserting structures drive the silicon steel sheets to be inserted into the coil bobbin. The shape of these silicon steel sheets is usually E-shaped or U-shaped. Since the two inserting structures are relatively distributed, the silicon steel sheets inserted into the coil bobbin by the inserting structures are also relatively distributed.

[0004] When silicon steel sheets are inserted into the coil frame, the relatively distributed silicon steel sheets will be stacked in an overlapping manner. When the overlapping silicon steel sheets are inserted into the coil frame, there will be a gap between two silicon steel sheets distributed in the same direction. In order to make the silicon steel sheets on the coil frame work stably, it is also necessary to insert I-shaped silicon steel sheets into the gap.

[0005] Since the I-shaped silicon steel sheet is inserted into the interior of two E-shaped silicon steel sheets or between two U-shaped silicon steel sheets, the insertion of the I-shaped silicon steel sheet has high process requirements. Currently, there is no good I-shaped silicon steel sheet insertion equipment on the market. Usually, the I-shaped silicon steel sheet is inserted manually. This method of inserting silicon steel sheets not only consumes more manpower, but also reduces the insertion efficiency of silicon steel sheets.

[0006] At the same time, when the I-shaped silicon steel sheet is inserted between two adjacent silicon steel sheets, the worker's hand is likely to come into contact with the bent corner of the silicon steel sheet. This makes it easy for the worker's hand to be pricked by the bent corner of the silicon steel sheet, which in turn poses a significant safety risk when manually inserting the I-shaped silicon steel sheet. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to propose a mechanized assembly structure for transformers to solve the problems mentioned above.

[0008] To achieve the above objectives, the present invention provides a mechanized assembly structure for a transformer, including a movable base with placement slots evenly spaced on the movable base, a height adjustment structure distributed above the movable base, telescopic shells fixed at equal intervals on the height adjustment structure, a telescopic plate sliding inside the telescopic shell, a supporting magnetic block fixed at the lower end of the telescopic plate, and an mounting plate adsorbed on the lower part of the supporting magnetic block.

[0009] The top walls of the telescopic plate and the inner cavity of the telescopic shell are fixed with spring telescopic rods and auxiliary telescopic rods. The side walls of the telescopic shell are fixed with displacement sensors. The supporting magnetic block is opposite to the receiving end of the placement slot. A rotating assembly is distributed on one side of the placement slot. A magnetic suction component is fixed to the top wall of the inner cavity of the telescopic shell. A magnetic block is fixed to the upper part of the telescopic plate.

[0010] In the above technical solution, the rotating assembly further includes a mounting plate that slides on the movable seat, a rotating motor is mounted on the mounting plate near the placement slot, and a rotating head is fixed to the output end of the rotating motor.

[0011] In the above technical solution, the lower end of the mounting plate is further fixed with a base plate, a moving track is fixed on the base plate, the moving seat slides on the moving track, a moving hydraulic cylinder is fixed at one end of the base plate, and the output end of the moving hydraulic cylinder is fixed to the moving seat.

[0012] In the above technical solution, a supporting hydraulic cylinder is further fixed at the part of the movable seat near the placement groove, the output end of the supporting hydraulic cylinder passes through the placement groove, and a supporting block is fixed at the end where the supporting hydraulic cylinder and the placement groove pass through.

[0013] In the above technical solution, the height adjustment structure further includes a support rail and a sliding rail fixed to one side of the base plate. A lead screw rotates inside the sliding rail. A connecting rod slides inside both the sliding rail and the support rail. The connecting rod inside the sliding rail is threadedly connected to the lead screw. A drive motor is fixed to the upper end of the sliding rail. The output shaft of the drive motor is fixed to the lead screw.

[0014] In the above technical solution, the height adjustment structure further includes a conveyor seat distributed above the movable seat, and a placement cavity is provided on the conveyor seat above the placement groove, and a through hole is provided on the bottom wall of the placement cavity.

[0015] In the above technical solution, a mounting box is further fixed on the conveyor seat above the placement cavity, and the telescopic shell is fixed at equal intervals inside the mounting box, with the inner cavity of the mounting box communicating with the inner wall of the placement cavity.

[0016] In the above technical solution, the cross-sections of the supporting magnetic block and the telescopic plate are both rectangular strips, the supporting magnetic block and the telescopic plate are fitted through the through hole, and the mounting piece is also fitted through the through hole.

[0017] In the above technical solution, the spring telescopic rods are distributed on both sides of the auxiliary telescopic rods, the spring telescopic rods and the auxiliary telescopic rods are distributed in parallel, and the telescopic plate does not contact the displacement sensor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this structure, after the external controller controls the rotary motor to drive the coil frame to rotate through the rotary head, the external controller controls the extended end of the support hydraulic cylinder to drive the support block to abut against the coil frame. Then the rotary head stops working and waits for the extended end of the support hydraulic cylinder to reset. After that, the extended end of the support hydraulic cylinder will drive the coil frame to reset through the support block. This facilitates the height adjustment structure to drive the mounting piece to be inserted into the gap between the two silicon steel sheets, thereby realizing the automatic flipping of the part of the coil frame that inserts the mounting piece, which facilitates the automatic insertion of the mounting piece into the coil frame.

[0020] 2. When the mounting plate in this structure is inserted into the gap between the two silicon steel sheets, the lower end of the mounting plate will abut against the bottom wall of the inner cavity of the placement slot. At this time, the mounting plate completes the insertion work on the coil frame. As the height adjustment structure continues to move downward, the telescopic shell will accommodate the length of the telescopic plate. The working ends of the spring telescopic rod and the auxiliary telescopic rod will be squeezed by the telescopic plate. The displacement sensor will also detect the length of the working end of the spring telescopic rod, and thus determine whether the mounting plate has completed the insertion between the two silicon steel sheets.

[0021] 3. When the supporting magnetic block in this structure is not working, the height adjustment structure will drive the telescopic shell to reset. The magnetic suction component is an electromagnet that can be purchased on the market, and the magnetic block component is a magnetic block that can be purchased on the market. The magnetic poles of the magnetic suction component and the magnetic block component attract each other. When the external controller controls the magnetic suction component to work, the magnetic suction component will drive the telescopic plate to reset through the magnetic block component, which will facilitate the subsequent placement of the mounting plate under the supporting magnetic block by the external equipment, so as to realize the internal loading of the height adjustment structure by the external equipment.

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] During transformer assembly, I-shaped silicon steel sheets are inserted into the interior of two E-shaped silicon steel sheets or between two U-shaped silicon steel sheets. This makes the insertion of I-shaped silicon steel sheets a process with high requirements. Currently, there is no good I-shaped silicon steel sheet insertion equipment on the market. Usually, I-shaped silicon steel sheets are inserted manually. This method of inserting silicon steel sheets not only consumes a lot of manpower, but also reduces the insertion efficiency of silicon steel sheets. In order to solve the above problems, the following structure is proposed.

[0034] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution:

[0035] The present invention is a mechanized assembly structure for a transformer, including a movable base 13, on which placement slots 12 are provided at equal intervals. A height adjustment structure is distributed above the movable base 13, and telescopic shells 33 are fixed at equal intervals on the height adjustment structure. A telescopic plate 31 slides inside the telescopic shell 33. A supporting magnetic block 32 is fixed at the lower end of the telescopic plate 31, and an mounting piece 4 is adsorbed on the lower part of the supporting magnetic block 32.

[0036] The top walls of the inner cavities of the telescopic plate 31 and the telescopic shell 33 are fixed with a spring telescopic rod 35 and an auxiliary telescopic rod 36. The side walls of the telescopic shell 33 are fixed with a displacement sensor 34. The supporting magnetic block 32 is opposite to the receiving end of the placement slot 12. A rotating component is distributed on one side of the placement slot 12. The top wall of the inner cavity of the telescopic shell 33 is fixed with a magnetic suction component 39. The upper part of the telescopic plate 31 is fixed with a magnetic block component 310.

[0037] In actual use, the external robotic arm drives the coil frame with E-shaped or U-shaped silicon steel sheets to be placed inside the placement slot 12. At this time, the moving seat 13 can store the coil frame through the placement slot 12. When the E-shaped or U-shaped silicon steel sheets are inserted into the coil frame, there will be a gap between the two silicon steel sheets distributed in the same direction. In order to make the silicon steel sheets on the coil frame work stably, it is also necessary to insert I-shaped silicon steel sheets inside the gap between the silicon steel sheets.

[0038] When the movable seat 13 moves the coil frame to below the support magnetic block 32, the rotating component can rotate the coil frame by ninety degrees. At this time, the gap between the two silicon steel sheets will be opposite to the mounting plate 4, which makes it easier for the height adjustment structure to drive the I-shaped silicon steel sheet to be inserted into the gap between the two silicon steel sheets.

[0039] When the mounting plate 4 is distributed above the movable base 13, the height adjustment structure can drive the telescopic plate 31 to move down through the telescopic shell 33, thereby enabling the telescopic plate 31 to drive the mounting plate 4 to move down through the supporting magnetic block 32, so that the mounting plate 4 can be inserted into the gap between the two silicon steel sheets.

[0040] When the mounting piece 4 is inserted into the gap between the two silicon steel sheets, the lower end of the mounting piece 4 will abut against the bottom wall of the inner cavity of the placement slot 12. At this time, the mounting piece 4 completes the insertion work on the coil frame. As the height adjustment structure continues to move down, the telescopic shell 33 will accommodate the working length of the telescopic plate 31. The working ends of the spring telescopic rod 35 and the auxiliary telescopic rod 36 will be squeezed by the telescopic plate 31. The displacement sensor 34 will also detect the working length of the spring telescopic rod 35, and thus determine whether the mounting piece 4 has completed the insertion between the two silicon steel sheets.

[0041] It should be noted that the mounting piece 4 shown in this document is an I-shaped silicon steel sheet. The I-shaped silicon steel sheet is magnetic. The supporting magnetic block 32 drives the mounting piece 4 to be fixed on the telescopic plate 31. The supporting magnetic block 32 is an electromagnet that can be purchased on the market. When the displacement sensor 34 detects that the working end of the spring telescopic rod 35 has reached the preset value, the displacement sensor 34 can send a signal to the control end of the supporting magnetic block 32. At this time, the supporting magnetic block 32 does not work, thereby realizing the separation of the supporting magnetic block 32 from the mounting piece 4.

[0042] When the supporting magnetic block 32 is not working, the height adjustment structure will drive the telescopic shell 33 to reset. The magnetic suction component 39 is an electromagnet that can be purchased on the market, and the magnetic block component 310 is a magnetic block that can be purchased on the market. The magnetic poles of the magnetic suction component 39 and the magnetic block component 310 attract each other. When the external controller controls the magnetic suction component 39 to work, the magnetic suction component 39 will drive the telescopic plate 31 to reset through the magnetic block component 310, which will facilitate the subsequent placement of the mounting plate 4 under the supporting magnetic block 32 by external equipment.

[0043] It should be added that the telescopic shell 33, spring telescopic rod 35, auxiliary telescopic rod 36 and telescopic plate 31 need to be made of non-magnetic materials.

[0044] Example 2: Please refer to Figures 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, after the external controller controls the rotary motor 18 to drive the coil frame to rotate through the rotary head 17, the external controller controls the extended end of the support hydraulic cylinder 16 to drive the support block to abut against the coil frame. Then, the rotary head 17 stops working and waits for the extended end of the support hydraulic cylinder 16 to reset. The extended end of the support hydraulic cylinder 16 will drive the coil frame to reset through the support block, thereby facilitating the height adjustment structure to drive the I-shaped silicon steel sheet to be inserted into the gap between the two silicon steel sheets.

[0045] The rotating assembly includes a mounting plate 14 that slides on the movable seat 13. A rotary motor 18 is mounted on the mounting plate 14 near the placement slot 12. A rotating head 17 is fixed to the output end of the rotary motor 18.

[0046] The lower end of the mounting plate 14 is fixed with a base plate 1, and a moving rail 11 is fixed on the base plate 1. The moving seat 13 slides on the moving rail 11. A moving hydraulic cylinder 15 is fixed at one end of the base plate 1, and the output end of the moving hydraulic cylinder 15 is fixed to the moving seat 13.

[0047] A supporting hydraulic cylinder 16 is fixed at the part of the movable seat 13 near the placement groove 12. The output end of the supporting hydraulic cylinder 16 passes through the placement groove 12, and a supporting block is fixed at the end where the supporting hydraulic cylinder 16 and the placement groove 12 pass through.

[0048] When used under normal conditions, the external controller controls the extended end of the support hydraulic cylinder 16 to drive the moving seat 13 to move forward on the moving track 11. This allows the moving seat 13 to be not distributed below the height adjustment structure. The external robot arm drives the coil frame with E-shaped or U-shaped silicon steel sheets to be placed inside the placement slot 12.

[0049] When the coil frame is placed inside the placement slot 12, the external controller controls the extended end of the support hydraulic cylinder 16 to move the coil frame upward through the support block. The silicon steel sheet on the coil frame will approach the rotating head 17. The rotating head 17 is an electromagnet that can be purchased on the market. When the external controller controls the rotating head 17 to work, the extended end of the support hydraulic cylinder 16 is reset. At this time, the rotating head 17 will attract the silicon steel sheet on the coil frame. Then the external controller controls the rotating motor 18 to drive the coil frame to rotate 90 degrees through the rotating head 17. This will make the gap between the two silicon steel sheets opposite to the mounting plate 4.

[0050] When the external controller controls the rotary motor 18 to drive the coil frame to rotate through the rotary head 17, the external controller controls the extended end of the support hydraulic cylinder 16 to drive the support block to abut against the coil frame. Then the rotary head 17 stops working and waits for the extended end of the support hydraulic cylinder 16 to reset. The extended end of the support hydraulic cylinder 16 will drive the coil frame to reset through the support block, which will facilitate the height adjustment structure to drive the I-shaped silicon steel sheet to be inserted into the gap between the two silicon steel sheets.

[0051] The height adjustment structure includes a support rail 2 and a sliding rail 21 fixed to one side of the base plate 1. A lead screw 22 rotates inside the sliding rail 21. A connecting rod slides inside both the sliding rail 21 and the support rail 2. The connecting rod inside the sliding rail 21 is threadedly connected to the lead screw 22. A drive motor 24 is fixed to the upper end of the sliding rail 21. The output shaft of the drive motor 24 is fixed to the lead screw 22.

[0052] The height adjustment structure also includes a conveyor seat 23 distributed above the movable seat 13. A placement cavity 38 is provided on the conveyor seat 23 above the placement groove 12. A through hole 37 is provided on the bottom wall of the placement cavity 38.

[0053] An installation box 3 is fixed on the conveyor seat 23 above the placement cavity 38. The telescopic shell 33 is fixed at equal intervals inside the installation box 3. The inner cavity of the installation box 3 is connected to the inner wall of the placement cavity 38.

[0054] The cross-sections of the supporting magnetic block 32 and the telescopic plate 31 are both rectangular strips. The supporting magnetic block 32 and the telescopic plate 31 are connected to the through hole 37. The mounting piece 4 is also connected to the through hole 37.

[0055] The spring telescopic rods 35 are distributed on both sides of the auxiliary telescopic rods 36. The spring telescopic rods 35 and the auxiliary telescopic rods 36 are distributed in parallel. The telescopic plate 31 does not contact the displacement sensor 34.

[0056] In actual use, the external robotic arm can drive the mounting piece 4 to be placed inside the placement cavity 38. Then, the external controller controls the support magnetic block 32 to work. When the support magnetic block 32 works, it will attract the mounting piece 4. Then, the external controller controls the drive motor 24 to work. The output shaft of the drive motor 24 drives the lead screw 22 to rotate in the forward direction. At this time, the connecting rod will drive the conveyor seat 23 to move down. During the downward movement of the conveyor seat 23, the external controller controls the magnetic suction component 39 to stop working. At this time, the working ends of the spring telescopic rod 35 and the auxiliary telescopic rod 36 will be reset. When the working ends of the spring telescopic rod 35 and the auxiliary telescopic rod 36 are reset, the side wall of the telescopic plate 31 will rub against the inner wall of the telescopic shell 33, thereby enabling the telescopic plate 31 to drive the mounting piece 4 to slowly pass through the through hole 37 through the support magnetic block 32, thereby enabling the mounting piece 4 to extend out from the inside of the placement cavity 38.

[0057] When the mounting piece 4 extends out of the placement cavity 38, the lead screw 22 drives the conveyor seat 23 to move down, which enables the support magnetic block 32 to drive the mounting piece 4 to be inserted into the coil frame, and simultaneously located between the two silicon steel sheets on the coil frame.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
