Description

Technical Field

[0001] This invention belongs to the field of automatic stacking of transformer cores, and specifically relates to a feeding and correction device for an automatic stacking production line of transformer cores. Background Technology

[0002] Currently, the manufacturing of transformer cores in China is almost entirely done manually, which is inefficient, error-prone, and labor-intensive. With the rapid development of the power industry, manually manufactured transformer cores can no longer meet market demand. Automated lamination production lines first separate silicon steel sheets at the automatic feeding port. During this process, uneven core stock can cause the separated silicon steel sheets to deviate from the center of the guide rail at the automatic feeding port, leading to jamming and even production line shutdowns, thus impacting production efficiency. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide a material feeding and correction device for an automatic transformer core stacking production line, which can overcome the above problems or at least partially solve or alleviate them.

[0004] This invention proposes a feeding and correction device for an automatic transformer core stacking production line, comprising:

[0005] A pair of segmented guide rails, the two segmented guide rails being arranged side by side;

[0006] Two drive shafts, each of which is longitudinally arranged at the lower part of one of the segmented guide rails;

[0007] Multiple alignment rollers, each of which is fixed on the drive shaft;

[0008] Two drive motors are provided, each of which is located at one end of the outer side of one of the segmented guide rails. The main shaft of the drive motor is directly or indirectly connected to the transmission shaft, driving the correction wheel to roll outwards from the segmented guide rails.

[0009] The present invention also has the following optional features.

[0010] Optionally, it also includes a guard plate, which is made of a non-magnetic material. The guard plate is disposed on the inner side of the upper part of each of the segmented guide rails, and the inner side of the guard plate is tangent to the wheel surface of the correction wheel.

[0011] Optionally, it also includes a first set of correction wheels and a second set of correction wheels, the first set of correction wheels and the second set of correction wheels are respectively disposed in the rectangular notches at both ends of the segmented guide rail, and the main shafts of the first set of correction wheels and the second set of correction wheels are connected to both ends of the transmission shaft.

[0012] Optionally, each of the segmented guide rails has multiple rectangular notches on its lower side, and the correction wheel, the first correction wheel group, and the second correction wheel group are respectively located in each of the rectangular notches.

[0013] Optionally, a transmission mechanism is connected between the drive motor and the main shaft of the first correction wheel set.

[0014] Optionally, the first and second correction wheel sets each include a wheel seat and a roller, the roller being rotatably mounted in the wheel seat via a wheel axle, and the wheel seat being fixedly connected to the segmented guide rail.

[0015] Optionally, the correction wheel and the roller are made of non-metallic materials.

[0016] The automatic transformer core stacking production line feeding and correction device of the present invention drives the segmented guide rails set on both sides of the feeding port. The drive motor set on the segmented guide rails drives the transmission shaft and the correction wheel to rotate in opposite directions, realizing online correction of the silicon steel sheet column. This ensures that each silicon steel sheet is centered within the range between the segmented guide rails on both sides of the feeding port, which can avoid material jamming or machine stoppage caused by silicon steel sheet segmentation during the operation of the automatic stacking machine. Its structure is simple, highly reliable, and can realize efficient stacking production of transformer cores. Attached Figure Description

[0023] Example 1

[0024] refer to Figure 1 , Figure 2 and Figure 3The present invention provides a feeding and correction device for an automatic transformer core stacking production line, comprising: a pair of segmented guide rails 5, two drive shafts 3, multiple correction wheels 4, and two drive motors 1; the two segmented guide rails 5 are arranged side by side; each drive shaft 3 is rotatably disposed at the lower part of one segmented guide rail 5; each correction wheel 4 is fixed on the drive shaft 3; each drive motor 1 is disposed at one end of the outer side of one segmented guide rail 5, and the main shaft of the drive motor 1 is directly or indirectly connected to the drive shaft 3, driving the correction wheel 4 to roll in the outer direction of the segmented guide rail 5.

[0025] When stacking transformer cores on an automated stacking production line, the silicon steel sheet column 9 is first positioned at the feeding port. Then, several silicon steel sheets 8 are placed between two slitting guide rails 5 using slitting technology. At the same time, a correction device is used to correct the silicon steel sheets 8 that did not enter the area between the two slitting guide rails 5 during slitting and place them into the slitting guide rails 5, thus completing the slitting work before stacking. Finally, the material-grabbing robot grabs the silicon steel sheets at the slitting guide rails 5 for stacking.

[0026] When the correction device corrects the silicon steel sheet that has not entered the two segmented guide rails 5, the correction wheel 4 fixed on the transmission shaft 3 is driven by the drive motor 1 to rotate in the opposite direction. If the silicon steel sheet 8 in the gradually rising silicon steel sheet column 9 is deviated, the silicon steel sheet 8 that has deviated out of the range of the two segmented guide rails 5 will first contact the correction wheel 4 on one of the segmented guide rails 5. Under the rotation of the correction wheel 4, it moves towards the middle, and finally ensures that the deviated silicon steel sheet 8 is corrected to the area between the two segmented guide rails 5.

[0027] Example 2

[0028] refer to Figure 1 Based on embodiment 1, it also includes a guard plate 7, which is made of non-magnetic material. The guard plate 7 is disposed on the inner side of the upper part of each segmented guide rail 5, and the inner side of the guard plate 7 is tangent to the wheel surface of the correction wheel 4.

[0029] As the core column 8 rises to the feeding port, the silicon steel sheet 9 on the core column 8 is corrected by multiple correction wheels 4 on the two side guide rails 5, and then reaches between the guard plates 7 on the two guide rails 5. The guard plates 7 are tangent to the wheel surfaces of each correction wheel 4, which can straighten each silicon steel sheet 9 sent to the feeding port.

[0030] Example 3

[0031] refer to Figure 1 and Figure 2 Based on embodiment 1, it also includes a first correction wheel group 2 and a second correction wheel group 6.

The main shafts of the first correction wheel group 2 and the second correction wheel group 6 are connected to both ends of the transmission shaft 3.

[0032] The first and second alignment wheel sets 2 and 6, together with the drive shaft 3 and multiple alignment wheels 4 fixed on the drive shaft 3, form a whole. The first and second alignment wheel sets 2 and 6 can be removed from the segmented guide rail 5 and then disassembled together with the drive shaft 3 and multiple alignment wheels 4.

[0033] Example 4

[0034] refer to Figure 1 Based on embodiment 3, each segmented guide rail 5 has multiple rectangular notches on its lower side, and the correction wheel 4, the first correction wheel group 2 and the second correction wheel group 6 are respectively located in each rectangular notch.

[0035] The segmented guide rail 5 can separate each correction wheel 4 through a rectangular notch, while allowing the first correction wheel group 2, the second correction wheel group 6 and each correction wheel 4 to be close to the inner side of the segmented guide rail 5. The lower ends of the first correction wheel group 2, the second correction wheel group 6 and each correction wheel 4 extend out of the rectangular notch, so that they can contact the skewed silicon steel sheet 9 as soon as possible.

[0036] Example 5

[0037] refer to Figure 1 Based on embodiment 3, a pulley transmission mechanism 10 is connected between the drive motor 1 and the main shaft of the first correction wheel group 2. The pulley transmission mechanism is prior art and will not be described in detail here.

[0038] The drive motor 1 is fixed on the outside of the segmented guide rail 5. The main shaft of the drive motor 1 is connected to the main shaft of the first correction wheel group 2 through a transmission mechanism 10. The transmission mechanism 10 can be a gear transmission mechanism or a belt transmission mechanism, etc.

[0039] Example 6

[0040] refer to Figure 1 , Figure 2 and Figure 4 Based on embodiment 1, the first correction wheel group 2 and the second correction wheel group 6 respectively include a wheel seat 11 and a roller 12. The roller 12 is rotatably mounted in the wheel seat 11 through a wheel axle, and the wheel seat 11 is fixedly connected to the segmented guide rail 5.

[0041] The first alignment wheel group 2 and the second alignment wheel group 6 are respectively fixed in the rectangular notches at both ends of the segmented guide rail 5 through wheel seats 11, and the rotating shaft of their rollers 12 is connected to the transmission shaft 3 where the alignment wheel 4 is located.

[0042] Example 7
