[0002] Silicon steel sheet, also known as silicon steel strip, is cold-rolled electrical steel and one of the important materials for manufacturing electrical equipment such as transformers and motors. Silicon steel sheet has the characteristics of low hysteresis, low energy loss, low iron loss, high magnetic permeability, etc., which can effectively reduce the electromagnetic sound and energy loss of the equipment during operation.

[0003] 90° direct shear silicon steel sheets are a type of silicon steel sheets and are often used in transformers. The existing direct shear silicon steel sheets are produced by cutting silicon steel strips as raw materials. The silicon steel sheets formed after cutting need to be manually carried to packaging boxes for packaging. Since the silicon steel sheets are thin, it is not easy for workers to pick up the silicon steel sheets, thereby reducing the packaging efficiency of the silicon steel sheets.

[0006] By adopting the above technical scheme, the unfolded silicon steel strip is sheared into a narrow silicon steel strip by the longitudinal shearing mechanism and rolled into a narrow silicon steel strip coil. Then the narrow silicon steel strip coil is unfolded and sheared into a silicon steel sheet by the transverse shearing mechanism. The clamping and conveying mechanism conveys the silicon steel sheet formed by the transverse shearing to the placing mechanism, and the placing mechanism places the silicon steel sheet into the packaging box. Compared with the method of manually picking up the silicon steel sheet into the packaging box, this scheme improves the convenience of transferring the silicon steel sheet, thereby improving the packaging efficiency of the silicon steel sheet.

The drive member 22 in this embodiment is a drive motor 221, and the drive motor 221 is fixedly arranged on the mounting block 282. The output shaft of the drive motor 221 is fixedly connected to the drive shaft 23 through a coupling. The longitudinal cutter 24 is annular, and its inner diameter is adapted to the outer diameter of the drive shaft 23. The longitudinal cutter 24 is sleeved on the drive shaft 23. The longitudinal cutters 24 in the upper and lower groups correspond to each other one by one, and the two corresponding longitudinal cutters 24 are staggered to achieve staggered shearing of the silicon steel strip. The longitudinal cutter 24 is directly sleeved on the drive shaft 23, which can reduce the installation error of the longitudinal cutter 24, improve the concentricity of the longitudinal cutter 24 and the drive shaft 23, and thus improve the accuracy of silicon steel strip cutting.

The opposite sides of the two ridges 64 are provided with traction grooves 65 for the narrow silicon steel strip to be inserted. The narrow silicon steel strip is leveled by the S-shaped automatic feeder 42 and then slides onto the cutting support table 63. At this time, the two edges of the narrow silicon steel strip are inserted into the corresponding traction grooves 65. The traction grooves 65 guide the narrow silicon steel strip, so that the stability of the narrow silicon steel strip sliding on the cutting support table 63 can be guaranteed.

[0050] Reference Figure 5 , Figure 6The traction mechanism 5 in this embodiment includes two traction rollers 51, which are installed on the cutting support table 63 for vertical rotation and driven by an external motor. The narrow silicon steel belt passing through the traction groove 65 enters between the two traction rollers 51. The two traction rollers 51 abut against the narrow silicon steel belt and, driven by the motor, pull the narrow silicon steel belt to move, thereby achieving traction of the narrow silicon steel belt.

The piston rod of the hydraulic cylinder 62 is fixedly connected to the back of the cross-cutting knife 61. The hydraulic cylinder 62 drives the cross-cutting knife 61 to cut the narrow silicon steel strip on the cutting support platform 63. The motor driving the traction roller 51, the S-shaped automatic feeder 42, and the motor of the unfolding frame 41 are controlled by a control system to realize the intermittent movement of the narrow silicon steel strip. The hydraulic cylinder 62 cooperates with the intermittent movement of the narrow silicon steel strip to cut the narrow silicon steel strip to form a silicon steel sheet.

[0052] Reference Figure 5 , Figure 6 and Figure 7 The clamping conveying mechanism 7 is arranged downstream of the cross-cutting knife 61, and includes two groups of conveyor belt devices 71 arranged opposite to each other up and down. The conveyor belt device 71 in this embodiment includes a conveying plate 711, a conveying belt 712 and two conveying wheels 713.

The electromagnet 83 is controlled to be on and off by a timer. In conjunction with the use of the manipulator 81, the silicon steel sheet on the lower conveyor belt 712 is adsorbed and detached.

[0055] When the robot 81 drives the electromagnet 83 to move to the silicon steel sheet on the conveyor belt 712 below, the electromagnet 83 is energized to adsorb the silicon steel sheet to ensure the stability of the adsorption of the silicon steel sheet. Then the robot 81 places the silicon steel sheet into the packing box 9, the electromagnet 83 is powered off, and the silicon steel sheet is separated from the electromagnet 83, so that the silicon steel sheet is placed in the packing box 9. By continuously repeating the above operation process, the silicon steel sheets can be neatly placed in the packing box 9, thereby improving the convenience of transferring and placing the silicon steel sheets.

The conveyor belt 712 transports the silicon steel sheet to the manipulator 81, and the manipulator 81 drives the electromagnet 83 to adsorb the silicon steel sheet and place it in the packaging box 9 to realize the production of the silicon steel sheet. Compared with the method of manually picking up the silicon steel sheet to the packaging box 9, this scheme improves the convenience of transferring the silicon steel sheet, thereby improving the packaging efficiency of the silicon steel sheet.
