Description

Technical Field

[0001] This invention belongs to the field of transformer core stacking technology, specifically relating to a dual-station automatic core stacking production line and method. Background Technology

[0002] In modern power systems, transformers are a crucial component, and the quality of their core iron core directly affects their performance and reliability. Traditional manual iron core stacking methods are labor-intensive and inefficient, while existing stacking production lines are linearly distributed, occupying large spaces and making it difficult to guarantee consistent stacking quality. Therefore, developing a highly automated, efficient, and stable dual-station automatic iron core stacking production line has significant practical implications and broad market prospects.

[0003] Chinese patent document CN118645355A discloses a dual-station automatic transformer core stacking production line, including a first station and a second station, at least one of which is arranged in a U-shape. The two stations operate independently to stack cores of the same or different specifications. The two stations have identical structures and are arranged in a mirror image. Each station includes a yoke feeding device, a yoke pre-positioning area, a three-column feeding device, a three-column pre-positioning area, a core stacking position, and a stacking center. Arranging the yoke feeding device, yoke pre-positioning area, core stacking position, three-column pre-positioning area, and three-column feeding device in a U-shape allows for simultaneous operation of both stations, improving production efficiency. Furthermore, the core specifications within the two stations are not limited, accommodating the stacking of multi-specification transformer core blanks. Compared to the traditional linear (or straight) layout, the U-shaped layout reduces the floor space, is more compact, and meets the cycle time requirements for core blank gripping and stacking. The two workstations in this document have the same structure and are arranged in a mirror image, which can accommodate the stacking of iron cores of different specifications. The feeding process requires the use of an external rotary conveyor to change the direction of the iron core materials to meet the requirements of feeding from the same side.

After installation, the automatic stacking production line for the iron cores at two workstations is concave in shape. Compared with a linear distribution, this invention has a compact structure and beautiful appearance, and to a certain extent reduces the floor space and operating space required.

[0038] Example 2:

[0039] Based on Example 1, such as Figure 2 As shown, a dual-station automatic iron core stacking production line includes a yoke double-feeding device 1 comprising a double-feeding frame 26, a yoke feeding base plate 13, two sets of yoke feeding mechanisms 27, a yoke feeding lifting mechanism 12, and a yoke double-feeding drive system. The bottom of the yoke feeding lifting mechanism 12 is connected to the bottom of the double-feeding frame 26. The lifting end of the yoke feeding lifting mechanism 12 is connected to the two sets of yoke feeding mechanisms 27 through the yoke feeding base plate 13. The two sets of yoke feeding mechanisms 27 are distributed on the left and right sides, and the two sets of yoke feeding mechanisms 27 are electrically connected to the yoke double-feeding drive system.

[0040] Specifically, the yoke column double feeding device 1 has two sets of yoke column feeding mechanisms 27 fixed in parallel on the yoke column feeding base plate 13. The feeding process uses a common set of yoke column double feeding drive system. The yoke column feeding lifting mechanism 12 is fixed to the bottom end of the yoke column feeding base plate 13, so that the two sets of yoke column feeding mechanisms 27 can be raised and lowered synchronously, which increases the resource utilization rate and saves feeding time.

[0041] Preferably, the yoke double feeding device 1 further includes a yoke segmentation mechanism 14, which is connected to the upper part of the double feeding frame 26 and is located above the two sets of yoke feeding mechanisms 27.

[0042] Specifically, by setting a yoke column segmenting mechanism 14 corresponding to its position directly above the yoke column feeding mechanism 27, the yoke column feeding and lifting mechanism 12 and the yoke column segmenting mechanism 14 cooperate to achieve segment compensation and ensure the accuracy and continuity of segmentation.

[0043] Preferably, the dual pre-positioning device 3 for the yoke column includes a pre-positioning frame 28 for the yoke column, a pre-positioning base plate 15 for the yoke column, and two sets of pre-positioning mechanisms for the yoke column.

The yoke gripping drive system is laterally connected between the two sets of yoke gripping motion modules 16. The yoke gripping drive system is electrically connected to the multiple gripping arms 29.

[0046] Specifically, the yoke gripping device 2 is driven by a yoke gripping drive system that simultaneously moves multiple gripping arms 29 up and down to grip and release. Two yoke gripping motion modules 16 longitudinally pass through the yoke double loading device 1 and the yoke double pre-positioning device 3, and are fixed on their left and right sides, enabling the yoke gripping device 2 to move longitudinally and horizontally. Through the yoke gripping device 2 and the yoke double pre-positioning device 3, the iron core is accurately gripped and positioned. This results in high work efficiency and a significant reduction in wafer retrieval time.

[0047] Example 3:

[0048] Based on Example 2, such as Figure 3 and Figure 5 As shown, a dual-station automatic iron core stacking production line includes a three-column double-feeding device 9 comprising a three-column double-feeding frame 30, a rotary platform 18, a three-column feeding lifting mechanism 17, and two sets of three-column feeding mechanisms 31.

[0049] Specifically, two sets of three-column feeding mechanisms 31 are fixed on the rotary platform 18. The rotary platform 18 turns the material tray, turns the material, and changes the direction of the material. The three-column feeding lifting mechanism 17 is fixed below the rotary platform 18 to realize the lifting and lowering of the three-column feeding mechanism 31, which increases the resource utilization rate and saves feeding time.

[0050] Preferably, the three-column double-feeding device 9 further includes a three-column segmentation mechanism 19, which is connected to the upper part of the three-column double-feeding frame 30 and is located above the two sets of three-column feeding mechanisms 31.

The centers of the two sets of three-column pre-positioning mechanisms are aligned with the centers of the two sets of three-column sheet-splitting mechanisms 19, respectively. The sheet placement guide rail of the three-column dual pre-positioning device 6 is aligned with the direction of the tray after the three-column feeding mechanism of the three-column dual feeding device 9 has rotated, and is horizontally perpendicular to the tray direction of the yoke-column dual feeding device 1.

[0054] Preferably, the three-column material gripping device 8 includes a three-column material gripping drive system, two sets of three-column material gripping motion modules 25 and multiple gripping arms 24.

[0055] Specifically, the three-column gripping device 8 is driven by a three-column gripping drive system that simultaneously moves multiple gripping arms 24 up and down to grip and release. Two sets of three-column gripping motion modules 25 run longitudinally through the three-column double loading device 9 and the three-column double pre-positioning device 6, and are fixed on their left and right sides, enabling the three-column gripping device 8 to move horizontally. The precise gripping and positioning of the iron core is achieved through the three-column gripping device 8 and the three-column double pre-positioning device 6. This results in high working efficiency and a significant reduction in wafer retrieval time.

[0056] Example 4:

[0057] Based on Example 3, such as Figure 6 As shown, a dual-station automatic stacking production line for iron cores includes a dual-station finished product output device 10 comprising two finished product output devices arranged side by side on the middle of the base frame 11.

The dual-station finished product output device 10 can simultaneously convey two stacking platforms 23, or independently convey a single station, making it highly functional.

[0061] Example 5:

[0062] Based on Embodiment 4, a dual-station automatic iron core stacking production line is provided, wherein the top of the yoke stacking device 4 and the top of the three-column stacking device 7 are both connected to the top frame 5 via a linear motor; the yoke stacking device 4 includes a yoke stacking frame 1, multiple gripping arms 3, and a width adjustment mechanism 1, with multiple gripping arms 3 connected to the yoke stacking frame 1, and the width adjustment mechanism 1 connected between two adjacent gripping arms 1; the three-column stacking device 7 includes a three-column stacking frame 1, multiple gripping arms 4, and a width adjustment mechanism 2, with multiple gripping arms 4 connected to the three-column stacking frame 1, and the width adjustment mechanism 2 connected between two adjacent gripping arms 4.

Multiple gripping arms are fixed on the yoke stacking frame 1, and a width adjustment mechanism 1 is provided between the gripping arms 3 to realize the automatic adjustment of the position of each gripping arm 3 to correspond with the yoke sheet material. At the same time, each pair of gripping arms 3 automatically adjusts its width and operates synchronously to ensure the accuracy of the spacing between the upper and lower yoke sheets. The yoke stacking device 4 moves horizontally and grips vertically directly above the yoke double pre-positioning device 3 and the dual-station finished product output device 10.

[0064] The top of the three-column stacking device 7 is fixed to the other side inside the top frame 5 by a linear motor. The gripping end is connected to the three-column double pre-positioning device 6. The three-column stacking device 7 and the yoke stacking device 4 share a linear motor. The three-column stacking device 7 has multiple gripping arms four fixed on the three-column stacking frame one. A width adjustment mechanism two is provided between the gripping arms four to automatically adjust the position of each gripping arm four. The gripping arm direction of the three-column stacking device 7 is horizontal and perpendicular to the gripping arm direction of the yoke stacking device 4. The three-column stacking device 7 moves horizontally and grips vertically directly above the three-column double feeding device 9 and the double-station finished product output device 10. The three-column stacking device 7 and the yoke stacking device 4 are located on the same straight line and run in opposite directions.

[0065] The simultaneous and precise stacking of the yoke stacking device 4 and the three-column stacking device 7 greatly reduces the stacking time and improves the stacking accuracy.

[0066] Example 6:

[0067] Based on Example 5, a stacking method for a dual-station automatic iron core stacking production line includes the following steps:

[0068] The double feeding device 1 of the yoke column feeds the iron core to the target position one. The yoke column grabbing device 2 grabs the iron core at the target position one and places it into the double pre-positioning device 3 of the yoke column. The double pre-positioning device 3 of the yoke column positions the iron core. The stacking device 4 of the yoke column grabs and stacks the positioned iron core, thus completing the stacking of the yoke columns at the two stations.

[0069] The three-column double feeding device 9 feeds the iron core to the target position two. The three-column gripping device 8 grips the iron core at the target position two and places it into the three-column double pre-positioning device 6. The three-column double pre-positioning device 6 positions the iron core. The three-column stacking device 7 grips and stacks the iron core positioned by the three-column double pre-positioning device 6, thus completing the three-column stacking of the two stations.

[0070] After multiple overlapping and repeated stacking of yoke columns and three-column stacks, the dual-station finished product output device 10 independently outputs single-station iron core finished products or simultaneously outputs dual-station iron core finished products.

[0071] Specifically, during feeding, the double-feeding device 1 lowers the material tray to a suitable position, and the yoke feeding mechanism 27 conveys it outward via chain drive to connect with the external material tray. Then, the material tray with stacked pieces is automatically fed inward via chain drive to a predetermined position. It can simultaneously feed four yoke material trays or feed them one by one. The triple-feeding device 9 feeds on the same side as the double-feeding device 1, and the feeding principle is the same. After the material tray is conveyed inward, the triple-feeding mechanism 31 is turned by the rotary platform 18 so that the material trays of the three columns are horizontal and perpendicular to the yoke material trays. After feeding is completed, the yoke feeding lifting mechanism 12 and the triple-feeding lifting mechanism 17 are activated to lift the material tray upward, so that the pieces connect with the slitting mechanism (yoke slitting mechanism 14 and triple-slitting mechanism 19), and the slitting mechanism magnetically suspends multiple pieces of material, completing the slitting of the yoke and the three columns. During gripping, the yoke gripping device 2 and the triple-gripping device... 8. Each component moves horizontally above the slitting mechanism via its motion module. The corresponding gripping arm moves downward to grab the sheet material from the slitting mechanism, then moves horizontally to the pre-positioning mechanism. The gripping arm lowers the sheet material, and the yoke double pre-positioning device 3 and the three-column double pre-positioning device 6 position the sheet material, preparing for the next step. During stacking, the yoke stacking device and the three-column stacking device operate interactively via linear motors. First, the gripping arm of the yoke stacking device grabs the sheet material from the yoke pre-positioning device, and the two pairs of gripping arms automatically adjust their width.
