Description

Technical Field

[0001] This invention relates to the field of automatic lamination technology, and in particular to an automatic lamination table for transformer cores that can automatically load and unload materials. Background Technology

[0002] In the production of transformer cores, the lamination process is a crucial step that determines core quality and production efficiency. Currently, transformer core lamination largely relies on manual labor or semi-automated equipment, which presents numerous technical challenges.

[0003] Among these issues, traditional equipment suffers from poor coordination between loading and unloading, and traditional suction nozzles cannot adapt to the gripping requirements of silicon steel sheets of different thicknesses, which can easily lead to material damage or detachment. The height connection between the material table and the stacking station requires manual adjustment, and the machine needs to be stopped when switching production specifications, which affects continuous production.

[0004] Furthermore, traditional equipment has insufficient adaptability and stability in lamination positioning. Existing rigid limiting structures can only limit in one direction and lack real-time pressure feedback and dynamic compensation, making them prone to interlayer misalignment. Switching to the production of irregular iron cores requires replacing special fixtures, which is costly and has a long changeover cycle.

[0005] In addition, traditional equipment suffers from low linkage accuracy between functional modules, with independent control of feeding, positioning, and stacking mechanisms, resulting in waiting time and low production efficiency. Single sensors are susceptible to environmental interference, leading to deviations in action and increasing the risk of equipment failure. Furthermore, the equipment layout lacks flexibility, with fixed layouts for the feeding mechanism and stacking station, making it less adaptable to different sites. The drive components are exposed to the elements, making them susceptible to dust and oil contamination, resulting in short service life and high maintenance workload.

[0006] For example, patent number CN114121475A discloses an overall layout for stacking iron cores into finished products. This patent uses a fixed suction nozzle structure, which cannot adaptively adjust the gripping pressure and height according to the thickness of the silicon steel sheets. When gripping thin silicon steel sheets, excessive pressure easily causes deformation, while insufficient pressure easily causes them to fall off. The height and posture adjustment of the material platform rely on manual operation, requiring machine shutdown when switching to different specifications of iron cores, resulting in excessively long changeover times, severely impacting continuous production efficiency, and causing excessively high material loss rates. Furthermore, the feeding, positioning, and stacking mechanisms use independent control logic, resulting in waiting times at each stage, excessively long cycle times, and reliance on only a single position sensor for status monitoring, making them susceptible to interference from workshop dust and oil. This leads to excessively high monthly equipment failure rates, accelerated component wear after long-term operation, and excessively high annual maintenance costs.

[0007] In addition, the feeding mechanism and stacking station layout of the above-mentioned patents are fixed and cannot be flexibly adjusted according to the size of the workshop. They have strict requirements for space and do not support modular expansion. If a stacking station or function upgrade is required, the main structure of the equipment needs to be modified. The modification cycle is long and the cost is high, making it difficult to meet the production needs of small batches and multiple varieties.

[0008] Therefore, there is a need for an automatic transformer core stacking table with automatic loading and unloading functions, precise positioning and adjustment, and coordinated operation of various mechanisms to solve the above-mentioned industry pain points. Summary of the Invention

[0023] 1. This invention uses a suction nozzle wrapped with a flexible anti-slip pad and a built-in negative pressure sensor. Combined with a first telescopic pump, it can adapt to the gripping pressure and height of silicon steel sheets of different thicknesses, avoiding material damage. The U-shaped frame, together with the second telescopic pump, drives the adjustment support plate to achieve automatic adjustment of the material posture and height without manual intervention.

The interlayer misalignment rate is controlled at an extremely low level, ensuring that each layer of silicon steel sheets can be precisely aligned during stacking. The interlayer misalignment rate does not exceed ±0.1 mm, effectively improving the overall quality and electromagnetic performance stability of the iron core, and significantly improving the magnetic permeability of the iron core.

[0025] 3. In this invention, the telescopic cylinder drives the upper working plate in conjunction with the drive gear inside the U-shaped moving groove to achieve arc-shaped conveying of the suction nozzle, shortening the path and avoiding interference.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 9 The present invention provides a technical solution:

[0041] An automatic stacking table for transformer cores with automatic loading and unloading includes a support leg 101 fixedly installed on the left side of the lower end face of the working plate 1 and at the front and rear edges. The bottom of the support leg 101 is provided with a liftable leveling pad, and a level sensor is embedded inside the leveling pad. The level sensor is electrically connected to an external controller.

[0042] Before the equipment is started, the level sensor automatically detects the levelness of the work plate 1. If the levelness deviation exceeds ±0.005°, the controller drives the lifting motor of the leveling foot pad to adjust the height of the corresponding support leg 101 until the work plate 1 reaches the preset level accuracy, ensuring that the subsequent stacking operation is not affected by tilt.

[0043] A through-hole 102 is provided from the upper end face to the lower end face of the working plate 1. A first limiting rod 103 is fixedly installed at the front and rear edges of the inner side of the through-hole 102. The outer side of the first limiting rod 103 is coated with a wear-resistant lubricating coating.

[0044] The inner middle of the two first limit rods 103 are fixedly installed with a first motor 104. The first motor 104 is a dual-axis servo motor and is electrically connected to an external controller. Threaded rods 105 are fixedly installed on the output shafts at both ends of the first motor 104. First slide rods 106 are threadedly rotatably installed on the circumferential surface of the threaded rods 105.

[0045] The first slide rod 106 has a first through groove 107 at both ends that matches the first limiting rod 103. The first limiting rod 103 and the first through groove 107 slide together. When the first motor 104 is started, the controller adjusts the motor speed according to the stacking requirements, drives the threaded rod 105 to rotate, and drives the first slide rod 106 to slide precisely along the first limiting rod 103. The sliding accuracy is controlled within ±0.01mm, which lays the foundation for the subsequent position adjustment of the frame plate 3.

[0046] The upper front and rear ends of the first slide rod 106 are provided with second through grooves 108. The upper end face of the working plate 1 is fixedly installed with a first limiting slide plate 109. The second slide rod 2 is slidably installed inside the first limiting slide plate 109. The middle of both sides of the second slide rod 2 is fixedly installed with connecting plates 201. The front and rear second through grooves 108 are slidably installed with a third slide rod 202. The middle of the third slide rod 202 is provided with a connecting groove 203 that is slidably connected to the connecting plate 201. The outer side of the connecting plate 201 is provided with a buffer pad.

[0047] The position sensor inside the first limiting slide plate 109 monitors the sliding position of the second slide rod 2 in real time. When the first slide rod 106 drives the third slide rod 202 to move, the connecting plate 201 slides synchronously in the connecting slot 203. The buffer pad absorbs the impact force of the collision to avoid wear of the parts. With the assistance of the external device, the second slide rod 2 moves to the preset stacking position. The position sensor sends a signal to the controller, and the first motor 104 stops running to ensure the accurate positioning of the frame plate 3.

[0048] The upper end face of the third slide bar 202 is provided with a moving groove 204. A moving block 205 is slidably installed inside the moving groove 204. An electromagnetic adsorption layer is fixedly installed inside the moving block 205, and a corresponding reverse magnetic field is set inside the moving groove 204.

[0049] After the frame plate 3 is placed on the upper surface of the second slide bar 2 and the third slide bar 202, the controller controls the electromagnetic adsorption layer to be energized. Therefore, the movable card block 205 can slide inside the movable groove 204. During the sliding process, it fits tightly with the frame plate 3, realizing the rapid fixation of the frame plate 3. The front and rear edges of the upper end of the frame plate 3 are slidably installed with limit step blocks 301. The inner side of the limit step block 301 is provided with a pressure sensing plate. The pressure sensing plate is electrically connected to the controller. During the stacking process, the pressure sensing plate provides real-time feedback on the contact pressure between the silicon steel sheet and the limit step block 301. If the pressure is abnormal, the controller adjusts the first motor 104 to drive the first slide bar 106 for fine adjustment to ensure that the stacking pressure is uniform and the gap is controlled within 0.03mm.

[0050] A telescopic cylinder 4 is fixedly installed on the left side of the working plate 1. An upper working plate 5 is fixedly installed on the telescopic rod of the telescopic cylinder 4. The upper working plate 5 can be moved up and down by the telescopic rod of the telescopic cylinder 4, and the height of the upper working plate 5 can be changed during the movement.

[0051] The lower end face of the upper working plate 5 is provided with a U-shaped moving groove 501. A drive gear 502 is rotatably installed inside the U-shaped moving groove 501. A dust cover is provided on the outside of the drive gear 502. A connecting shaft 503 is rotatably installed on the lower end face. A damping spring is fitted on the outside of the connecting shaft 503. The lower end is fixedly connected to the connecting frame 504.

[0052] It should be noted that the outer side of the drive gear 502 is a gear, while the inner side is a stator. Therefore, when energized, the drive gear 502 will move along the tooth groove path inside the U-shaped moving groove 501.

[0053] The lower ends of the two connecting shafts 503 extend to the outside of the U-shaped moving groove 501 and are jointly fixedly mounted with a connecting frame 504. Three first telescopic pumps 505 are fixedly mounted at equal intervals on the upper surface of the connecting frame 504. The telescopic rods of the first telescopic pumps 505 extend to the lower part of the connecting frame 504 and are fixedly mounted with support rods 506. Air pumps 507 are fixedly mounted on the upper parts of both ends of the support rods 506, and suction nozzles 508 are fixedly mounted on the lower ends of the air pumps 507. Figure 7 As shown.

[0054] Therefore, during use, when the telescopic cylinder 4 is activated, its telescopic rod will drive the upper working plate 5 to move up and down, thereby adjusting the height of the upper working plate 5 to meet the requirements of different sizes of transformer core laminations.

[0055] After the upper working plate 5 is moved to a suitable height, the drive gear 502 is powered on and starts to work. Since the gear on the outside of the drive gear 502 meshes with the tooth groove on the inner side of the U-shaped moving groove 501, the drive gear 502 will move horizontally along the tooth groove path inside the U-shaped moving groove 501 under the rotation of the drive gear 502, thereby driving the connecting shaft 503, the connecting frame 504 and the components installed on the connecting frame 504 to move together.

[0056] As the connecting frame 504 moves, the first telescopic pump 505 moves to the position above the transformer core laminations. At this time, the first telescopic pump 505 starts, and its telescopic rod extends downward, driving the support rod 506 to move downward, so that the air pump 507 and the suction nozzle 508 approach the transformer core laminations.

[0057] Once the suction nozzle 508 reaches the appropriate position, the air pump 507 starts working, generating negative pressure. A negative pressure sensor monitors the adsorption pressure in real time. If the pressure is lower than a preset value, the controller adjusts the air pressure of the air pump 507 to ensure stable adsorption of the material component 9, preventing it from falling off or being scratched. The suction nozzle 508 picks up the transformer core laminations. Then, the telescopic rod of the first telescopic pump 505 retracts upward, moving the support rod 506, air pump 507, suction nozzle 508, and the picked-up transformer core laminations upward. Next, the drive gear 502 continues to rotate, moving the entire device above the designated stacking position. The first telescopic pump 505 restarts, the telescopic rod extends downward, placing the transformer core laminations in the designated position. The air pump 507 stops working, and the suction nozzle 508 releases the transformer core laminations, completing one automatic loading and unloading process. This cycle repeats, achieving automatic lamination of the transformer core.

[0058] A mounting bracket 6 is provided on the lower right side of the upper working plate 5. Threaded holes are provided at the inner corners of the mounting bracket 6, and screws are installed inside the threaded holes to fix the mounting bracket 6 to the ground. Furthermore, sliding rods are slidably installed at the four corners of the top of the mounting bracket 6. The top of the sliding rods is fixedly connected to the lower end face of the upper working plate 5. Therefore, the state of the mounting bracket 6 will not be affected when the upper working plate 5 moves up and down.

[0059] Secondly, a symmetrical second telescopic pump 601 is fixedly installed on the inner bottom surface of the mounting frame 6, and U-shaped frames 7 are fixedly installed on both the front and rear sides near the edge of the upper end of the mounting frame 6. Adjustable support plates 701 are rotatably installed at equal intervals on the upper inner side of the U-shaped frames 7, and the upper front and rear sides of the adjustable support plates 701 have a trapezoidal structure, such as... Figure 9As shown, a limiting rod 702 is fixedly installed on the inner side of the U-shaped frame 7 and above the adjusting support plate 701. The limiting rods 702 are in pairs and are in contact with the upper outer side of the adjusting support plate 701. This prevents the adjusting support plate 701 from rotating again after returning to a horizontal state, ensuring that the adjusting support plate 701 remains horizontal. This also ensures that the upper inner surface of the two adjusting support plates 701 can be used to support the material plate 8. The upper surface of the material plate 8 holds the material component 9, such as... Figure 8 As shown.

[0060] Therefore, during use, when it is necessary to place material component 9 above material plate 8, the material plate 8, along with material component 9, is transported to the top of the second telescopic pump 601 via a conveyor belt or other device. The second telescopic pump 601 is then started, lifting the material plate 8 upwards. The material plate 8, along with material component 9, moves synchronously, pushing the adjusting support plate 701 to rotate. After passing the adjusting support plate 701, the adjusting support plate 701 automatically resets and then becomes horizontal under the action of the limit rod 702. At this time, the telescopic rod of the second telescopic pump 601 moves downwards, allowing the material plate 8 to be placed on the upper surfaces of the front and rear adjusting support plates 701. By repeating the above steps, multiple material components 9 can be loaded.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
