[0031] Among them, the lower transport plate driving device includes a first driving motor 1-11, a first lead screw 1-14, a first light rod 1-15, a first moving slider 1-32, a first lead screw nut 1-16, and a first connecting member 1-13; the first driving motor 1-11 drives the first lead screw 1-14, the first lead screw nut 1-16 of the first lead screw 1-14 is connected to the first moving slider 1-32, and the first moving slider 1-32 is sleeved on the first light rod 1-15; and the top of the first light rod 1-15 is connected to the first lead screw 1-32 through the first connecting member 1-13. 14; the first movable slider 1-32 is connected to the lower transport plate 1-30; the first drive motor 1-11 drives the first lead screw 1-14 to rotate, and the first lead screw 1-14 drives the first movable slider 1-32 to move along the first light rod through the first lead screw nut 1-16, and the first movable slider 1-32 drives the lower transport plate 1-30 to move downward; the lower transport plate 1-30 and the first movable slider 1-32 are connected by a hinge 1-27, that is, under the action of external force, the lower transport plate 1-30 can be flipped relative to the first movable slider 1-32.

[0032] The above-mentioned first driving motor 1-11 drives the first screw 1-14 after being decelerated by the reduction gear box 1-12.

[0033] The above-mentioned upper transport plate driving device includes a second driving motor 1-7, a second lead screw 1-23, a second rod 1-22, a second movable slider 1-8, a second lead screw nut 1-33, and a second connecting piece 1-24; the second driving motor 1-7 drives the second lead screw 1-23, the second lead screw nut of the second lead screw 1-23 is connected to the second movable slider 1-8, and the second movable slider 1-8 is mounted on the second rod 1-22; and the top of the second rod 1-22 is connected to the second lead screw 1-23 through the second connecting piece 1-24; the second movable slider 1-8 is connected to the upper transport plate; the second driving motor 1-7 drives the second lead screw 1-23 to rotate, and the second lead screw 1-23 drives the second movable slider 1-8 to move along the second rod 1-22 through the second lead screw nut 1-33, and the second movable slider 1-8 drives the upper transport plate 1-9 to move downward with the steel sheet.

[0034] The above-mentioned second drive motor 1-7 drives the second screw 1-23 after being decelerated by the reduction gear box.

[0035] The lower transport plate turning device in this embodiment includes a cylinder 1-20, a rack 1-19, and a gear 1-17; a cylinder slide 1-29 is vertically arranged on the outer shell, and the cylinder body of the cylinder 1-20 is connected to the cylinder slide 1-29 through a slide plate 1-21; the piston rod of the cylinder 1-20 is connected to a rack 1-19; the rack 1-19 is arranged in a limiting groove 1-18, and the cylinder 1-20 can push the rack 1-19 to make a linear motion, and the rack 1-19 is meshed with the gear 1-17. When the rack moves linearly, the gear 1-17 will rotate; the gear The central axis of the wheel 1-17 is fixed in a connecting plate fixed to the lower transport plate. When the rack 1-19 drives the gear 1-17 to rotate, the gear 1-17 can realize the synchronous rotation of the connecting plate, thereby realizing the flipping of the lower transport plate 1-30; the limiting groove 1-18 is connected to the above-mentioned first movable slider 1-32; it is connected to the above-mentioned first movable slider 1-32 through the limiting groove 1-18, so that when the lower transport plate driving device drives the lower transport plate to move up and down, the entire lower transport plate flipping device can move up and down with the lower transport plate, thereby realizing the flipping of the lower transport plate at any height position.

[0036] Furthermore, a plurality of upper limit rods 1-10 are arranged at the bottom of the upper transport plate 1-9; a plurality of lower limit rods 1-25 are arranged at the top of the lower transport plate 1-30; by arranging the upper limit rods 1-10 and the lower limit rods 1-25, the silicon steel sheets can be aligned up and down on the upper transport plate 1-9 and the lower transport plate 1-30.

[0037] Furthermore, a gravity sensor 1-26 is also provided on the lower transport plate 1-30; the gravity sensor measures the mass of the silicon steel sheets, calculates the number of silicon steel sheets according to the mass of a single silicon steel sheet, and establishes the accumulation of different numbers of silicon steel sheets under different magnetic requirements of different motors to realize subsequent automatic aluminum casting.

[0038] Furthermore, the upper limit rod 1-10 is a magnetic metal and has an adsorption effect, and can directly adsorb the silicon steel sheet to the bottom of the upper transport plate 1-9, and the upper limit rod 1-10 can be magnetically controlled by powering on or off, thereby achieving the adsorption or lowering of the silicon steel sheet.

[0039] Based on the above stacking device, this embodiment further provides a stacking method, and the specific working process is as follows:

[0040] The electromagnet 1-3 on the robot arm 1-1 places the silicon steel sheets on the silicon steel sheet stacking tray on the lower transport tray 1-30;

[0041] When the gravity sensor 1-26 on the lower transport plate 1-30 detects the weight, it counts, and at this time, the upper transport plate 1-9 starts to move downward, and the lower transport plate 1-30 starts to move upward;

[0042] During the transportation process, when the upper transport plate 1-9 moves to the top position of the lower transport plate 1-30, since an upper limit rod 1-10 is provided at the bottom of the upper transport plate 1-9, and the upper limit rod 1-10 has a certain magnetic force, the upper transport plate 1-9 can suck the silicon steel sheet from the lower transport plate 1-30 to its bottom and align it through the upper limit rod 1-10 with a built-in electromagnet;

[0043] Then, the lower transport tray flipping device controls the lower transport tray 1-30 to flip down or flip up, leaving a passage for the upper transport tray 1-9 to continue to move downward;

[0044] The upper transport plate 1-9 stops moving after being transported to the position where the lower base 1-28 is located. At this time, the upper limit rod 1-10 is controlled to lose its magnetic force, and the silicon steel sheet falls downward to the specified position, and the whole work is completed.

[0045] It needs to be further explained that when the lower transport tray 1-30 is flipped upward, the upper transport tray 1-9 needs to move upward (backward) a certain distance before the lower transport tray 1-30 is flipped upward again; when flipping down, the lower transport tray 1-30 can be flipped down directly, but it is necessary to ensure that after the lower transport tray 1-30 is flipped down, it does not affect the lowering distance of the silicon steel sheet.

[0046] Example 2

[0047] In this embodiment, another rotor silicon steel sheet stacking device is proposed, which is different from Example 1 in that the lower transport plate driving device in this embodiment can be changed into a lower transport plate fixing device, that is, the lower transport plate does not move up and down, and only the upper transport plate moves up and down; at this time, the lower transport plate can be directly hinged to the side wall of the shell, or a connecting plate can be provided on the side wall, the lower transport plate is hinged to the connecting plate, and then the lower transport plate flipping device is connected to the lower transport plate, driving the lower transport plate to flip downward, and the function of stacking silicon steel sheets can still be realized.

[0048] The rotor silicon steel sheet stacking devices proposed in the above two embodiments are devices that can realize automatic alignment, counting and precise placement of silicon steel sheets, which will greatly improve the efficiency of this process, reduce dependence on manpower, and reduce the risk of human error, thereby promoting the intelligentization and automation of the production process. This not only helps to improve production efficiency, but also effectively reduces production costs and improves overall production safety and reliability.
