Description

Technical Field

[0001] The present invention belongs to the technical field of silicon steel sheet conveying, and more specifically, relates to a silicon steel sheet conveying device with a dispensing function. Background Art

[0002] Silicon steel sheets are key materials for manufacturing transformer cores. Through their excellent magnetic conductivity and low loss characteristics, they play a role in concentrating magnetic flux and reducing energy loss in transformers, and are core components indispensable for ensuring the efficient and stable operation of transformers. However, before silicon steel sheets become transformer cores, they need to go through strict screening and rejection and other dispensing processes before being sent to the stacking equipment through the conveying equipment for stacking and forming.

[0003] Currently, the production method of silicon steel sheets mainly relies on an open-loop production mode that does not adjust according to real-time feedback during the production process. In this mode, the control of the accuracy of silicon steel sheets entirely depends on manual measurement of the calibrated sheets after each material change of the front-end transverse shearing equipment, comparison with the current parameters, and then data compensation of the front-end transverse shearing equipment according to the comparison results. The existence of this situation leads to the subsequent accuracy of silicon steel sheets being overly dependent on the performance of the front-end transverse shearing equipment, resulting in the problem of difficulty in ensuring the continuous stability of the subsequent accuracy of silicon steel sheets. In addition, although manual sampling inspection can be used to reduce the defective rate of subsequent silicon steel sheets in a small range, this dispensing process including measurement, comparison, data compensation, sampling inspection, and rejection of materials is not only cumbersome but also needs to be repeated multiple times, seriously restricting the dispensing and conveying efficiency of silicon steel sheets. Therefore, this application proposes a silicon steel sheet conveying device with a dispensing function to solve the above problems. Summary of the Invention

The vision screening camera is used to screen each group of silicon steel sheets and is configured to transmit the information of the defective products screened out to the material rejection mechanism and the front-end transverse cutting equipment.

[0009] The material rejection mechanism includes a material rejection component configured to be able to reject the defective products according to the information and transfer the remaining silicon steel sheets in each group of silicon steel sheets to the buffer table;

[0046] Embodiment: Figure 1 Fig. 5 shows a schematic structural diagram of a silicon steel sheet conveying device with a dispensing function from a first perspective according to an embodiment of the present invention; Figure 2 Fig. 7 shows a schematic structural diagram of a silicon steel sheet conveying device with a dispensing function from a second perspective according to an embodiment of the present invention; Figure 3 Fig. 9 shows a schematic structural diagram of a silicon steel sheet conveying device with a dispensing function from a third perspective according to an embodiment of the present invention; Figure 4 Fig. 11 shows a schematic structural diagram of a magnetic attraction assembly according to an embodiment of the present invention.

[0047] Referring to Figures 1 - 4 , an embodiment of the present invention provides a silicon steel sheet conveying device with a dispensing function, which is configured to be disposed between a front-end transverse cutting device and a rear-end stacking device;

[0048] The silicon steel sheet conveying device includes a conveying mechanism, a screening mechanism, a rejection mechanism, and a buffer table 1;

[0049] The conveying mechanism includes a conveying component having a conveyor belt 2, and the conveying component is used to sequentially convey each group of silicon steel sheets in several groups of silicon steel sheets in the front-end transverse cutting device to the rear-end stacking device;

[0050] The screening mechanism includes a vision screening camera installed at the starting end of the conveyor belt 2. The vision screening camera is used to screen each group of silicon steel sheets and is configured to be able to transmit the information of the screened defective products to the rejection mechanism and the front-end transverse cutting device. The defective products include calibrated sheets and defective sheets. The calibrated sheet is the first silicon steel sheet cut by the front-end transverse cutting device after each material change for correcting its current parameters, and the defective sheet is a silicon steel sheet cut by the front-end transverse cutting device under the corrected parameters that does not meet the corrected parameters and is used for further correction;

[0051] The rejection mechanism includes a rejection component configured to be able to reject defective products according to the information and transfer the remaining silicon steel sheets in each group of silicon steel sheets to the buffer table 1;

[0052] After the front-end horizontal cutting device processes the supplementary silicon steel sheets corresponding to the defective products according to the information, the material rejection component can place the supplementary silicon steel sheets and the remaining silicon steel sheets on the conveyor belt 2 in a preset order.

[0053] In a specific embodiment, each group of silicon steel sheets includes five silicon steel sheets arranged in a preset order along the conveying direction. Specifically, the five silicon steel sheets are an upper jaw sheet, a lower jaw sheet, a left side sheet, a right side sheet, and a middle column sheet with different shapes. Of course, it should be realized that the arrangement order, shape, and quantity of the silicon steel sheets during conveying can be preset according to the type of transformer core or actual production requirements, and the present invention is not limited thereto.

[0054] In a specific embodiment, the conveying mechanism further includes a carrier table 3 for installing the conveying component. Moreover, the carrier table can also carry the part of the silicon steel sheet that extends beyond the conveyor belt, thereby effectively preventing the silicon steel sheet from falling off the conveyor belt and ensuring the integrity of the silicon steel sheet.

[0055] In one embodiment, the conveying component includes a driving unit for driving the conveyor belt 2.

[0056] In a specific embodiment, the driving unit includes a driving motor 4, a driving roller 5, and a driven roller 6 respectively arranged at both ends of the carrier table 3. The driving motor 4 is used to drive the conveyor belt 2 sleeved on the driving roller 5 and the driven roller 6 to rotate.

[0057] Specifically, the driving motor drives the driving roller through a synchronous belt, thereby driving the conveyor belt to rotate. During this process, the driven roller can play a role in tensioning and guiding the conveyor belt to ensure its running stability.

[0058] In one embodiment, the conveying mechanism further includes a plurality of magnetic adsorption components. Each magnetic adsorption component in the plurality of magnetic adsorption components includes a magnetic plate 7 arranged below the conveyor belt 2 and a first air cylinder 8 for driving the magnetic plate 7 to move away from or close to the conveyor belt 2, as Figure 4 shown. Specifically, the magnetic plate can be combined with the first air cylinder to moderately adsorb the silicon steel sheets on the conveyor belt. This can not only improve the stability of the silicon steel sheets during conveying, prevent situations such as displacement that affect their subsequent stacking operations, but also facilitate the removal operation of the silicon steel sheets, making the conveying mechanism have higher operation flexibility.

[0059] In addition, the magnetic plate can also be replaced by a vacuum chuck, and the suction force of the chuck is controlled by adjusting the air pressure intensity set by the air source to achieve moderate adsorption of the silicon steel sheets.

[0060] In a specific embodiment, the visual screening camera is installed on the front cross-cutting device at the starting end of the conveyor belt 2 (not shown in the figure). After screening out defective products, it can give the material rejection mechanism enough operation time. While achieving the rapid rejection of defective products, it can also reduce the impact on the conveyance of other non-defective silicon steel sheets, thereby greatly improving the conveyance efficiency of the silicon steel sheets. Specifically, the visual screening camera is a prior art, and its structure and working principle will not be elaborated here.

[0061] Specifically, since the front cross-cutting device needs to change materials at least 20 times to complete a core manufacturing process, and after each material change, it is necessary to manually measure and compare the calibrated material sheet and perform data compensation on the front cross-cutting device. Moreover, due to the limitation of the manual measurement accuracy during this process, the comparison result error of the silicon steel sheets is relatively large. Therefore, considering the improvement of the accuracy of the silicon steel sheets, multiple measurements, comparisons, and data compensations are required. However, it takes about 10 minutes for manual workers to complete one measurement and comparison process, which directly leads to a reduction in the conveyance efficiency of the silicon steel sheets.

[0062] In the present invention, the visual screening camera is combined with the conveying mechanism, so that during the material change and the cutting process of the front cross-cutting device, it can quickly and accurately perform data self-adaptive correction based on the information of the defective products captured in real time, completely abandoning the above-mentioned manual participation in the allocation method. While ensuring the screening accuracy of the silicon steel sheets, it also significantly improves the efficiency of the conveyance and subsequent stacking operations of the silicon steel sheets by at least 3 hours compared with manual operations.

[0063] In addition, it should be noted that after each material change of the front cross-cutting device, it first performs the first data correction based on the calibrated material sheet, and then performs the second data correction according to the feedback information of the subsequent defective material sheets to ensure the continuous stability of the accuracy of the subsequent silicon steel sheets.

[0064] In a specific embodiment, the material rejection mechanism further includes a mounting frame 9, and the material rejection assembly is arranged above the conveyor belt 2 through the mounting frame 9.

[0065] In an embodiment, the material rejection assembly includes a lifting unit, a linear module 10, and a material suction frame 12 having a plurality of suction cups 11. The material suction frame 12 can move away from or close to the conveyor belt 2 through the lifting unit and move above the buffer stock table 1 through the linear module 10.

[0066] In a specific embodiment, the lifting unit includes a second cylinder 13 and a third cylinder 14 respectively arranged at both ends of the material suction frame 12. Specifically, the upper ends of the second cylinder and the third cylinder are both connected to the linear module so that they can move along the linear module.

[0067] In a specific embodiment, the reject mechanism further includes a recycling cart 15 for rejecting defective products. Specifically, the linear module is arranged to extend from above the buffer table to above the recycling cart, so that the suction cup can move to the position of the recycling cart to realize the rejection of the grabbed defective products.

[0068] In one embodiment, the control ends of the vision screening camera, the motor, the first cylinder, the second cylinder and the third cylinder are all electrically connected to a controller (not shown in the figure) to achieve coordinated control of the silicon steel sheet conveying device.

[0069] When the silicon steel sheet conveying device of the present invention is in use, first, the vision screening camera screens the silicon steel sheets conveyed to the starting end of the conveyor belt. If defective products are screened out, the information of the defective products is transmitted to the reject component and the front-end transverse shearing equipment. Then, the reject component drives the suction cup to approach the conveyor belt through the linear module, the second cylinder and the third cylinder. When the defective product is conveyed below the suction cup, the defective product is grabbed, and then moved above the recycling cart through the linear module to reject the defective product. Then, the suction cup moves above the conveyor belt again to sequentially grab the other silicon steel sheets in each group of silicon steel sheets and place them on the buffer table. Next, the conveyor belt continues to convey each group of silicon steel sheets placed thereon. At the same time, the front-end transverse shearing equipment processes supplementary silicon steel sheets corresponding to the defective products and conveys them to the conveyor belt. After screening, they are conveyed below the suction cup. Finally, the suction cup places the supplementary silicon steel sheets and the remaining silicon steel sheets on the conveyor belt in a preset order, and then conveys them to the rear stacking equipment through the conveyor belt in sequence for stacking and forming.

[0070] It should be noted that the silicon steel sheet conveying device of the embodiment of the present invention can screen, reject and supplement each silicon steel sheet on the conveyor belt through the above structure, so as to ensure the quality of each silicon steel sheet while ensuring the sequentiality of the conveyance of each group of silicon steel sheets, facilitating subsequent stacking and forming.

[0071] In addition, the silicon steel sheet conveying device of the embodiment of the present invention only performs operations such as rejecting materials when defective products appear, so the influence on the conveying efficiency of good-quality silicon steel sheets is relatively small, realizing the efficient conveyance of good-quality silicon steel sheets.

[0072] The silicon steel sheet conveying device with a dispensing function proposed by the present invention includes a conveying component with a conveyor belt and used to sequentially convey each group of silicon steel sheets in several groups of silicon steel sheets in the front-end transverse shearing equipment to the rear-end stacking equipment; a screening mechanism, including a vision screening camera installed at the starting end of the conveyor belt, which is used to screen each group of silicon steel sheets and is configured to be able to transmit the information of the screened defective products to the material removal mechanism and the front-end transverse shearing equipment; a material removal mechanism, including a material removal component configured to be able to remove defective products according to the information and transfer the remaining silicon steel sheets in each group of silicon steel sheets to the buffer table; after the front-end transverse shearing equipment processes supplementary silicon steel sheets corresponding to the defective products according to the information, the material removal component can place the supplementary silicon steel sheets and the remaining silicon steel sheets on the conveyor belt in a preset order.

[0073] Therefore, compared with the existing method that relies on the open-loop production mode and manual dispensing of silicon steel sheets, the silicon steel sheet conveying device of the present invention has significant progress. On the one hand, it can accurately screen silicon steel sheets at the starting end of the conveyor belt by using a vision screening camera, which not only ensures the efficiency of the screening process but also greatly improves the screening accuracy; on the other hand, it can quickly remove defective products by using the material removal component, effectively breaking through the inherent limitations of manual operation in terms of rhythm and efficiency; on the other hand, the front-end transverse shearing equipment can quickly complete data adjustment based on the instantaneously feedback information to achieve closed-loop compensation of the production process, thereby improving the dispensing efficiency. In addition, the setting of the buffer table also guarantees the sequentiality of silicon steel sheets during the conveying process.

[0074] In summary, the silicon steel sheet conveying device of the present invention realizes the accurate dispensing and efficient conveying of silicon steel sheets through its high integration, automation, and high efficiency performance.

[0075] Although the above describes one or more embodiments of the present invention, those of ordinary skill in the art should know that the present invention can be implemented in any other form without departing from its gist and scope. Therefore, the above-described embodiments are illustrative rather than restrictive, and many modifications and substitutions are obvious to those of ordinary skill in the art of this technology without departing from the spirit and scope of the present invention as defined by the appended claims.
