Description

[0001] This application is a divisional application of application number CN202510493028.1, filed on April 18, 2025, entitled "An apparatus and method for automatically receiving silicon steel sheets". Technical Field

[0002] This invention relates to the field of silicon steel sheet production and processing equipment, and particularly to a silicon steel sheet receiving assembly, an automatic receiving device having a silicon steel sheet receiving assembly, and a method for receiving silicon steel sheets applied to the automatic receiving device. Background Technology

[0003] In the production and manufacturing of silicon steel sheets, the double-layer receiving and unloading of silicon steel sheets is a critical step in the production process. The accuracy and efficiency of its operation directly affect the continuity of the entire production process and the product quality. Currently, in the production practice of double-layer silicon steel sheets, the common receiving methods mainly rely on fixed gantry cranes for unloading, or unloading through external hoists.

[0004] However, during the hoisting process, fixed gantry cranes are prone to collisions and friction between silicon steel sheets due to the large number of stacked layers and uneven weight distribution. This is especially problematic when double-layered silicon steel sheets need to be output from different heights, as the gantry crane struggles to precisely control the receiving position, easily causing scratches, surface wear, or localized deformation of the silicon steel sheets. Similarly, external hoists require manual adjustment for each unloading operation to receive and transport silicon steel sheets at different heights. This provides insufficient cushioning and protection for the silicon steel sheets during receiving, easily causing damage. Furthermore, the instability of manual operation can lead to misaligned stacking or drops during transport, significantly impacting product quality.

[0005] In addition, traditional material receiving methods lack the ability to transfer double-layer silicon steel sheets in a step-by-step and unified manner. They usually require processing the silicon steel sheets output from the upper and lower conveying layers separately, resulting in inconsistent output heights. Subsequent discharges require additional equipment adjustments or manual handling, which is not only cumbersome and inefficient, but also further increases the probability of silicon steel sheets being damaged during multiple transfers.

[0006] The aforementioned problems severely restrict the automation level of the silicon steel sheet production process and reduce the stability of product quality. There is an urgent need for a technical solution that can adapt to the output characteristics of double-layer silicon steel sheets, reduce material receiving damage, and facilitate material discharge. Summary of the Invention

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a silicon steel sheet receiving assembly that can adapt to different feeding heights, flexibly respond to changes in production scenarios, ensure the smooth transfer of silicon steel sheets of different heights to the rollers and their smooth outward conveyance, improve production efficiency, enhance production flexibility and stability, and has high practical value.

[0008] The present invention also proposes an automatic receiving device having the above-mentioned silicon steel sheet receiving assembly, and a method for receiving silicon steel sheets applied to the automatic receiving device.

[0009] The silicon steel sheet receiving assembly according to the present invention comprises: frame; A conveyor line is installed on the frame. The conveyor line includes a conveyor frame, a conveyor chain, a conveyor motor, multiple spaced rollers, and multiple pressure sprockets. The conveyor motor is connected to and drives the conveyor chain to move in a closed loop. The conveyor chain is connected to and drives the multiple rollers to rotate together. The pressure sprockets are located between two rollers and below the rollers. The conveyor chain is wound around the lower side of the pressure sprockets. The conveyor frame is provided with multiple receiving slots, each of which corresponds to a pressure sprocket and is located above the pressure sprocket. A lifting assembly is disposed on the frame. The lifting assembly includes a lifting motor and a lifting frame. The lifting motor is connected to and drives the lifting frame to move in the vertical direction. The lifting frame can hold a receiving plate for receiving silicon steel sheets. The lifting frame has a frame structure and includes multiple support beams. The support beams are staggered with the roller and can sink downward into the receiving groove to transfer the receiving plate onto the roller.

[0010] The silicon steel sheet receiving assembly according to the present invention has at least the following beneficial effects: the lifting motor of the lifting assembly drives the lifting frame to move vertically, adapting to different unloading heights. After receiving the material on the receiving plate, it can transfer it to the rollers. Furthermore, the conveyor line uses multiple rollers arranged at intervals, which can both stably support the receiving plate and facilitate the conveying of the receiving plate. For example, when the silicon steel sheet sorting machine releases silicon steel sheets at a high height, the lifting frame can quickly and accurately move to the corresponding height, avoiding the problem of receiving difficulties or poor receiving effect caused by height mismatch. By adjusting the height of the lifting frame, the receiving plate can be positioned appropriately for receiving materials. After receiving the materials, the receiving plate can sink into the roller, transferring the plate onto the roller. By transferring the double-layered silicon steel sheets onto the roller in stages, the rolling characteristics of the roller allow the silicon steel sheets to be smoothly conveyed to subsequent processes, achieving a uniform discharge height. This enables convenient and stable transfer using a handcart or automatic transfer using an AGV to the next process, reducing damage to the silicon steel sheets during receiving, improving production efficiency, and enhancing the flexibility and stability of production.

[0011] According to some embodiments of the present invention, the silicon steel sheet receiving assembly includes a screw rotatably disposed on the frame and a screw block fixedly connected to the lifting frame. The screw is arranged vertically, the lifting frame is slidably disposed on the frame in the vertical direction, the lifting motor is connected to and drives the screw to rotate, and the screw block is threadedly driven to the screw to drive the lifting frame to move in the vertical direction.

[0012] According to some embodiments of the present invention, the silicon steel sheet receiving assembly has two screws and two screw blocks, the two screw blocks are respectively fixedly connected to both ends of the lifting frame, and the lifting motor drives the two screws to rotate together.

[0013] According to some embodiments of the present invention, the silicon steel sheet receiving assembly further includes a drive shaft and two reducers. The screw is arranged in a one-to-one correspondence with the reducers and is connected to the output side of the reducers. The lifting motor is connected to and drives the drive shaft to rotate. The two ends of the drive shaft are respectively connected to the input side of the reducers.

[0014] The automatic receiving device according to the present invention includes: a feeder for conveying silicon steel sheets and capable of releasing and dropping the silicon steel sheets; and a receiving unit including a shift motor and two silicon steel sheet receiving assemblies as described in the present invention, the two silicon steel sheet receiving assemblies being arranged opposite to each other, the shift motor being connected to and driving the two silicon steel sheet receiving assemblies to reciprocate linearly together, so as to drive one silicon steel sheet receiving assembly to enter laterally into the feeder and receive the stacked silicon steel sheets, and drive the other silicon steel sheet receiving assembly to move out of the feeder to unload the silicon steel sheets.

[0015] The automatic receiving device according to the present invention has at least the following beneficial effects: By setting an upper conveying layer and a lower conveying layer in the material handling machine, both of which can convey and release falling silicon steel sheets from their bottom surfaces, the device can flexibly adapt to silicon steel sheets in different conveying states, ensuring their smooth entry into the receiving stage and improving the adaptability of the device to different production conditions. Specifically, in the receiving unit, a shifting motor connects to and drives two opposing receiving components to reciprocate linearly. This design allows one receiving component to promptly enter the material handling machine laterally to receive stacked silicon steel sheets, while the other receiving component can simultaneously move out of the material handling machine for unloading, achieving continuous and efficient silicon steel sheet receiving and unloading, greatly improving efficiency. This design improves production efficiency and avoids production stoppages caused by asynchronous receiving and unloading. Furthermore, the receiving assembly consists of a frame, conveyor line, and lifting components. The conveyor line stably supports the silicon steel sheets falling from the lower conveyor layer, while the lifting components effectively support the silicon steel sheets falling from the upper conveyor layer and accurately transfer them to the conveyor line. This layered design fully considers the receiving requirements of silicon steel sheets at different conveying heights and in different ways, ensuring the accuracy and stability of the silicon steel sheets' position during the receiving process. It effectively prevents damage caused by falling or collisions, improves product quality, and comprehensively ensures the reliability and stability of the equipment operation, providing strong support for the smooth operation of the silicon steel sheet production process.

[0016] According to some embodiments of the present invention, the automatic receiving device further includes a track, which is arranged horizontally perpendicular to the conveying direction of the silicon steel sheet, and two silicon steel sheet receiving assemblies are slidably disposed on the track.

[0017] According to some embodiments of the present invention, the automatic receiving device for receiving silicon steel sheets includes a plurality of rollers, which are disposed around the bottom of the frame. The rollers are in rolling cooperation with the track, and the shifting motor is connected to and drives two rollers symmetrically disposed on the frame to rotate together.

[0018] According to some embodiments of the present invention, the automatic receiving device further includes a connecting rod, the two ends of which are fixedly connected to two silicon steel sheet receiving assemblies to drive the two silicon steel sheet receiving assemblies to move together.

[0019] According to some embodiments of the present invention, the automatic receiving device further includes two anti-collision rubbers, which are respectively disposed on opposite sides of the two silicon steel sheet receiving assemblies.

[0020] The silicon steel sheet receiving method according to the present invention is applied to an automatic receiving device as described in the present invention; the material handling machine is provided with an upper conveying layer and a lower conveying layer, the bottom surfaces of the upper conveying layer and the lower conveying layer are used to convey silicon steel sheets and can release and drop the silicon steel sheets; The silicon steel sheet receiving method includes the following steps: Receiving: The lower conveying layer of the material sorting machine drops the silicon steel sheet onto the conveying line, and the upper conveying layer of the material sorting machine drops the silicon steel sheet onto the lifting assembly; Shifting: After receiving the material, the shifting motor runs to move the silicon steel sheet receiving assembly out of the material handling machine and move another silicon steel sheet receiving assembly into the material handling machine; Manual unloading: After relocation, the silicon steel sheet located on the conveyor line is manually removed, and then the lifting assembly is operated to transfer the silicon steel sheet on the lifting assembly to the conveyor line and then remove it.

[0021] The silicon steel sheet receiving method according to the present invention has at least the following beneficial effects: In the receiving step, the lower and upper conveying layers of the material handling machine accurately convey the silicon steel sheets to the conveyor line and the lifting assembly, respectively, ensuring that the silicon steel sheets can enter the receiving device in an orderly manner; in the shifting step, the shifting motor drives the receiving assembly to work alternately, so that the receiving and unloading process of the silicon steel sheets can be carried out continuously, improving production efficiency; in the manual unloading step, the silicon steel sheets on the conveyor line are removed first, and then the lifting assembly is operated to transfer the silicon steel sheets on the lifting assembly to the conveyor line and then remove them. This sequence arrangement is reasonable, avoids operational chaos, and ensures the smooth progress of the unloading process. The entire silicon steel sheet receiving method is closely integrated with the structural design of the device, giving full play to the various advantages of the device, further improving the automation level, work efficiency and product quality of the silicon steel sheet production process, and reducing labor costs and safety risks.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] Therefore, such as Figures 1 to 5As shown, this invention provides an automatic receiving device for silicon steel sheets, comprising a feeder 500 and a receiving unit 600. The feeder 500 is used to transport silicon steel sheets and release them for dropping. For example, the feeder 500 magnetically attracts the silicon steel sheets for transport and releases them at a higher position to allow them to fall. Further, the receiving unit 600 includes a shift motor 610 and two receiving components 620. The two receiving components 620 are arranged opposite each other. The shift motor 610 connects to and drives the two receiving components 620 to reciprocate linearly, causing one receiving component 620 to laterally enter the feeder 500 and receive stacked silicon steel sheets, while simultaneously moving the other receiving component 620 out of the feeder 500 to unload the silicon steel sheets. It is easy to understand that the silicon steel sheets are conveyed and dropped by the feeder 500, and the shift motor 610 in the receiving unit 600 drives two opposing receiving components 620 to reciprocate linearly. When one receiving component 620 enters the feeder 500 to receive the stacked silicon steel sheets, the other receiving component 620 can move out of the feeder 500 at the same time to unload the sheets. This avoids the problem of having to stop the machine to transport the sheets after receiving and stacking them, which is a traditional device. It realizes continuous operation of silicon steel sheet conveying and stacking, which greatly improves production efficiency, reduces the increase in labor costs, equipment wear and tear and interference with the production cycle caused by downtime, and ensures the smoothness and efficiency of production.

[0031] Refer to Figure 1 and Figure 2In some embodiments of the present invention, the receiving unit 600 includes a track 630, which is horizontally arranged perpendicular to the conveying direction of the silicon steel sheets. Two receiving components 620 are slidably disposed on the track 630, making the movement of the receiving components 620 more stable and precise, and enabling them to easily extend into the feeder 500 to receive silicon steel sheets. Furthermore, the track 630 provides a clear movement path for the receiving components 620, limiting unnecessary shaking and offset, and ensuring that under the drive of the shift motor 610, the receiving components 620 can accurately perform linear reciprocating motion along a predetermined trajectory. Whether entering the feeder 500 to receive silicon steel sheets or removing them from the feeder 500 for unloading operations, the precision of the movements is guaranteed, thereby improving the reliability and stability of the entire device and contributing to improving the quality and efficiency of silicon steel sheet receiving, stacking, and unloading. Furthermore, in some embodiments of the present invention, the receiving assembly 620 includes a frame 100 and a plurality of rollers 110. The rollers 110 are disposed around the bottom of the frame 100, and the rollers 110 roll in cooperation with the track 630, greatly reducing the friction when the receiving assembly 620 moves on the track 630. Compared with sliding, the rolling friction coefficient is much smaller, allowing the receiving assembly 620 to move more easily and smoothly on the track 630. This not only reduces the power consumption required for the shift motor 610 to drive the receiving assembly 620, reducing energy costs, but also further improves the speed and response performance of the receiving assembly 620. It can complete the actions of receiving material into the feeder 500 and unloading material from the feeder 500 more quickly, thereby improving the working efficiency of the entire automatic silicon steel sheet receiving device. Specifically, the shift motor 610 connects to and drives two rollers 110 symmetrically arranged on the frame 100 to rotate together. It is easy to understand that the symmetrically arranged rollers 110, driven by the shift motor 610, enable a more balanced power transmission. The synchronous rotation of the two rollers 110 ensures that the frame 100 experiences more even force on the track 630, preventing problems such as instability, jamming, or deviation from the track 630 caused by uneven force on one side. This design guarantees the smooth movement of the receiving assembly 620, ensuring it maintains a precise position and orientation during the receiving and conveying of silicon steel sheets. This improves the neatness and accuracy of silicon steel sheet stacking, thereby enhancing product quality. Optionally, the symmetrically arranged rollers 110 are fixedly connected by a rotating rod, and the shift motor 610 connects to and drives the rotating rod to rotate.

[0032] Refer to Figure 2In some embodiments of the present invention, the receiving unit 600 includes a connecting rod 640, the two ends of which are fixedly connected to two receiving components 620 to drive the two receiving components 620 to move together. It should be noted that the presence of the connecting rod 640 enhances the coordination and overall integrity between the two receiving components 620. Under the action of the shifting motor 610, the connecting rod 640 ensures that the two receiving components 620 always maintain a consistent relative position and synchronously perform linear reciprocating motion. This not only enables the two receiving components 620 to complete their work more coordinatedly and smoothly when alternating between receiving and unloading operations, but also avoids problems such as collisions and interference that may occur due to asynchronous movement of the two receiving components 620, further improving the reliability and stability of the device operation and ensuring the smooth progress of silicon steel sheet receiving, stacking, and unloading operations. Furthermore, during actual operation, due to potential vibrations or movement deviations in the equipment, the two receiving components 620 may collide when approaching their limit positions or in unexpected situations. To address this, the receiving unit 600 includes two anti-collision rubbers 650, each positioned on one side opposite to the other of the two receiving components 620. The anti-collision rubbers 650 possess excellent cushioning properties, absorbing and dispersing the energy generated by the collision, thus preventing damage to the receiving components 620 from direct impact. For example, the anti-collision rubbers 650 may be made of polyurethane or rubber.

[0033] In some applications, 500 magnetic silicon steel sheet feeders are used to transport silicon steel sheets and release them at a higher position to allow them to fall. However, most existing feeding devices lack the ability to flexibly adjust the feeding height, failing to adapt quickly and accurately to different feeding heights according to actual needs. For example, when feeding at a higher position, it is inconvenient to manually remove the silicon steel sheets after feeding, while feeding at a lower position results in a larger falling distance for the silicon steel sheets, which may lead to significant positional deviations during the fall and poor feeding results. This often necessitates complex adjustments or even replacements of the equipment during production, increasing operational complexity and workload, severely impacting production efficiency, and reducing the continuity and stability of production.

[0034] In this regard, refer to Figure 3 and Figure 4In some embodiments of the present invention, the receiving assembly 620 includes a conveyor line 200 and a lifting assembly 300. The lifting assembly 300 can support the silicon steel sheets and transfer them to the conveyor line 200. Furthermore, the lifting assembly 300 can precisely adjust the height of the silicon steel sheets as needed, ensuring that the silicon steel sheets are accurately placed on the conveyor line 200, avoiding problems such as slippage and collisions caused by inconsistent heights. Simultaneously, the lifting assembly 300 also facilitates the stacking of silicon steel sheets, enabling them to be neatly stacked according to a set height and order, improving the quality and efficiency of silicon steel sheet stacking.

[0035] The conveyor line 200 includes multiple spaced rollers 210, and the lifting assembly 300 includes a lifting motor 310 and a lifting frame 320. The lifting motor 310 connects to and drives the lifting frame 320 to move vertically. The lifting frame 320 can hold the receiving plate 400 and can sink down into the rollers 210 to transfer the receiving plate 400 onto the rollers 210. It should be noted that the lifting motor 310 of the lifting assembly 300 drives the lifting frame 320 to move vertically, adapting to different material discharge heights. After the receiving plate 400 receives the material, it can transfer it onto the rollers 210. Furthermore, the conveyor line 200 uses multiple spaced rollers 210, which can both stably support the receiving plate 400 and facilitate the conveying of the receiving plate 400. For example, when the silicon steel sheet feeder 500 releases silicon steel sheets at a relatively high height, the lifting frame 320 can quickly and accurately move to the corresponding height, avoiding problems such as difficulty in receiving materials or poor receiving effect caused by height mismatch. In this regard, by adjusting the height of the lifting frame 320, the receiving plate 400 can be placed in a suitable position for receiving materials. After receiving the materials, the receiving plate 400 can sink into the roller 210, so that the receiving plate 400 is transferred to the roller 210, realizing a smooth transition of the silicon steel sheets from the receiving plate 400 to the conveyor line 200. Utilizing the rolling characteristics of the roller 210, the silicon steel sheets can be smoothly conveyed in subsequent processes. The whole process is smooth and continuous, further improving production efficiency.

[0036] When the receiving plate 400 is transferred onto the roller 210, in addition to manually pulling out the receiving plate 400, refer to... Figures 1 to 4 In some embodiments of the present invention, the conveyor line 200 includes a conveyor chain 220 and a conveyor motor 230. The conveyor motor 230 is connected to and drives the conveyor chain 220 in a closed-loop motion. The conveyor chain 220 is connected to and drives multiple rollers 210 to move together, making the power source of the conveyor line 200 more stable and reliable. The receiving plate 400 can be conveyed outward by operating the conveyor motor 230. For example, refer to... Figure 1The receiving plate 400 is conveyed outwards to the receiving trolley, allowing workers to transport the receiving plate 400 as a whole using the trolley. Furthermore, the closed-loop conveyor chain 220 ensures the synchronous rotation of each roller 210, preventing problems such as jamming or deviation of the silicon steel sheets during conveying due to differences in the rotational speed of individual rollers 210. Further, the conveyor line 200 includes multiple pressure sprockets 240, located between two rollers 210 and below them. The conveyor chain 220 is wound around the pressure sprockets 240 to allow space for the lowering of the lifting frame 320. On one hand, the presence of the pressure sprockets 240 effectively tensions the conveyor chain 220, preventing slackness during operation and ensuring that the conveyor chain 220 is always under appropriate tension, thereby ensuring the stability and accuracy of the chain drive. On the other hand, the reasonable arrangement of the pressure sprocket 240 provides the necessary space for the lifting frame 320 to descend, allowing it to smoothly sink between the rollers 210 when the receiving plate 400 needs to be transferred to the rollers 210. This avoids interference with the conveyor chain 220, ensuring the normal operation of the receiving assembly 620 and the smooth progress of the receiving operation. Furthermore, the conveyor line 200 includes a conveyor frame 250 with multiple receiving slots 2501. Each receiving slot corresponds to one of the pressure sprockets 240 and is located above it, further preventing interference with the conveyor chain 220 around the pressure sprocket 240 when the lifting frame 320 sinks into the receiving slot 2501, thus ensuring the stability of the conveyor line 200.

[0037] In some embodiments of the present invention, the lifting frame 320 has a frame structure, which has high structural strength and rigidity, and can withstand large weight and external forces. During the material receiving process, it can stably support and transfer the receiving plate 400 and the silicon steel sheets stacked on it, and is not easily deformed or damaged. Secondly, the frame structure is relatively lightweight and will not place an excessive load on the lifting motor 310, which is beneficial to the stable operation of the lifting motor 310 and extends its service life. Specifically, as... Figure 3 As shown, the lifting frame 320 includes multiple support beams 321, which are staggered from the rollers 210 and can sink downwards between the two rollers 210. This staggered arrangement of the support beams 321 better adapts to the arrangement of the rollers 210, avoiding potential collisions or slippage that could occur if the lifting frame 320 directly contacts the rollers 210 during descent, thus ensuring the safety and stability of the receiving plate 400 during transfer.

[0038] Refer to Figure 3 and Figure 4In some embodiments of the present invention, the lifting assembly 300 includes a screw 331 rotatably mounted on the frame 100 and a screw block 332 fixedly connected to the lifting frame 320. The screw 331 is vertically arranged, and the lifting frame 320 is slidably mounted on the frame 100 in a vertical direction. The lifting motor 310 is connected to and drives the screw 331 to rotate. The screw block 332 is threadedly engaged with the screw 331 to drive the lifting frame 320 to move in a vertical direction. The threaded drive method has significant advantages in terms of high transmission accuracy and good stability. Through the precise engagement of the screw 331 and the screw block 332, the lifting motor 310 can precisely control the rising and falling positions of the lifting frame 320, thereby achieving precise adaptation to different material feeding heights. Compared to traditional hydraulic or pneumatic drives, threaded drives are unaffected by external environmental factors (such as temperature and humidity), maintaining stable performance in various complex working environments. Furthermore, threaded drives have a self-locking function, ensuring the receiving assembly 620 can reliably operate at a preset height, thus improving equipment reliability. Specifically, there are two screws 331 and two screw blocks 332, each fixedly connected to both ends of the lifting frame 320. The lifting motor 310 drives both screws 331 to rotate together, effectively preventing tilting or swaying of the lifting frame 320 during movement, ensuring the smoothness and accuracy of the receiving plate 400 transfer process. Simultaneously, the dual-screw drive 331 also increases the load-bearing capacity of the lifting assembly 300, enabling it to handle heavier receiving plates 400 and silicon steel sheet loads, further enhancing equipment stability and reliability, extending its service life, and reducing the failure rate. Furthermore, the lifting assembly 300 includes a drive shaft 350 and two reducers 340. A screw 331 is arranged correspondingly to each reducer 340 and connected to the output side of the reducer 340. A lifting motor 310 is connected to and drives the drive shaft 350 to rotate. Both ends of the drive shaft 350 are connected to the input side of the reducer 340. It is easy to understand that the combined use of the drive shaft 350 and the reducers 340 can effectively adjust the speed and torque of the lifting motor 310, making it more suitable for the movement requirements of the lifting frame 320. Specifically, the reducers 340 can convert the high-speed rotation of the lifting motor 310 into the low-speed, high-torque output required by the screw 331, thereby ensuring that the lifting frame 320 can move smoothly and slowly, avoiding shaking or damage to the receiving plate 400 due to excessive speed. The drive shaft 350 evenly transmits the power of the lifting motor 310 to the reducer 340, ensuring that the two screws 331 can rotate synchronously, further improving the stability and reliability of the lifting assembly 300, and enabling the receiving assembly 620 to maintain good working performance under different load conditions.

[0039] Refer to Figure 5In some embodiments of the present invention, the feeder 500 is provided with an upper conveying layer 510 and a lower conveying layer 520. The bottom surfaces of both the upper and lower conveying layers 510 and 520 are used to convey silicon steel sheets and release them for dropping. The dual-layer design increases the conveying channel and bearing area of ​​the silicon steel sheets, meaning the device can process more silicon steel sheets simultaneously, greatly improving the conveying efficiency and meeting the high-capacity requirements of large-scale production. For example, for silicon steel sheets that need to be separated after being input from the feeder 500, multiple input silicon steel sheets can be alternately conveyed to the upper and lower conveying layers 510 and 520, achieving a reasonable interval for conveying the silicon steel sheets in the upper and lower conveying layers 510 and 520. Secondly, this design also has advantages in equipment layout and space utilization. Compared with the traditional single-layer conveying design, the structure of the upper and lower conveying layers 510 and 520 is more compact and reasonable, enabling more efficient silicon steel sheet conveying and processing within a limited space, and facilitating equipment maintenance and management.

[0040] It is easy to understand that the receiving plate on the lifting frame can also be placed on the conveyor line in advance (not shown in the figure). When manually unloading, the receiving plate on the conveyor line needs to be removed first, and then the lifting motor is run to place the receiving plate on the lifting frame on the conveyor line before removing it.

[0041] Refer to Figure 6 The silicon steel sheet receiving method according to an embodiment of the present invention is applied to an automatic silicon steel sheet receiving device according to an embodiment of the present invention. The silicon steel sheet receiving method includes the following steps: S100, receiving: the lower conveying layer 520 of the material handling machine 500 drops silicon steel sheets onto the conveyor line 200, and the upper conveying layer 510 of the material handling machine 500 drops silicon steel sheets onto the lifting assembly 300. S200, Shifting: After receiving the material, the shifting motor 610 runs to move the receiving assembly 620 out of the material handling machine 500 and move another receiving assembly 620 into the material handling machine 500; S300, Manual unloading: After relocation, the silicon steel sheets located on the conveyor line 200 are manually removed, and then the lifting assembly 300 is operated to transfer the silicon steel sheets on the lifting assembly 300 to the conveyor line 200 and then remove them.

[0042] It should be noted that in the receiving step, the lower conveying layer 520 and upper conveying layer 510 of the material handling machine 500 accurately convey the silicon steel sheets to the conveyor line 200 and the lifting assembly 300, respectively, ensuring that the silicon steel sheets can enter the receiving device in an orderly manner. In the shifting step, the shifting motor 610 drives the receiving assembly 620 to work alternately, so that the receiving and unloading process of silicon steel sheets can be carried out continuously, improving production efficiency. In the manual unloading step, the silicon steel sheets on the conveyor line 200 are removed first, and then the lifting assembly 300 is run to transfer the silicon steel sheets on the lifting assembly 300 to the conveyor line 200 before being removed. This sequence arrangement is reasonable, avoids operational chaos, and ensures the smooth progress of the unloading process. The entire silicon steel sheet receiving method is closely integrated with the structural design of the device, giving full play to the various advantages of the device, further improving the automation level, work efficiency and product quality of the silicon steel sheet production process, and reducing labor costs and safety risks.

[0043] Other configurations and operations of the silicon steel sheet receiving method according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
