[0036] On the basis of the first embodiment, the driving mechanism 120 includes a servo motor 121 , a gear 122 , a rack 123 , and a sliding groove 124 .

[0037] The frame 110 is installed on the fixed gantry 400, the servo motor 121 is fixedly connected to the frame 110, the gear 122 is drivingly connected to the output shaft of the servo motor 121, the rack 123 is meshingly connected to the gear 122, the rack 123 is fixedly connected to the fixed gantry 400, the sliding groove 124 is fixedly connected to the frame 110, and the sliding groove 124 is slidingly connected to the fixed gantry 400.

[0038] The adsorption mechanism includes a mounting frame 131, a vacuum suction cup 132, an adsorption cylinder 133, and an electromagnet 134. Figure 3 and Figure 4As shown in the figure, the mounting bracket 131 is fixedly connected to the bottom of the frame 110. There are several mounting brackets 131, and the several mounting brackets 131 are arranged in parallel. The vacuum suction cup 132 is connected to the adsorption cylinder 133. The vacuum suction cup 132 generates a vacuum through the adsorption cylinder 133, thereby realizing the adsorption effect on the silicon steel sheet. The adsorption cylinder 133 is fixedly connected to the middle position of the mounting bracket 131 along the length direction. Several vacuum suction cups 132 and adsorption cylinders 133 are evenly arranged. There are several electromagnets 134, and the several electromagnets 134 are evenly spaced on the mounting bracket 131. The electromagnet 134 is located at the peripheral position of the vacuum suction cup 132.

[0039] In the utility model, through several adsorption cylinders 133 with vacuum suction cups arranged evenly, after the yoke plate is grabbed by the vacuum suction cup 132, the yoke plate is adsorbed by the electromagnets arranged on the periphery. This grabbing method has an accurate adsorption position, a compact structure, and a light weight. It can adapt to yoke plates with different sheet lengths and widths, and has stronger flexibility than the method of using only vacuum suction cups.

[0040] The core yoke plate translation manipulator of the utility model further includes a positioning assembly 200.

[0041] The positioning assembly 200 includes a positioning pin 201 and a positioning pin adjusting mechanism 202. As Figure 6 shown, the positioning pin 201 is movably installed on the positioning pin adjusting mechanism 202, and the positioning pin adjusting mechanism 202 is used to adjust the position of the positioning pin 201 to adapt to the hole pitch of the positioning holes of silicon steel sheets with different sheet types.

[0042] As Figure 7 shown, the positioning pin adjusting mechanism 202 includes a positioning pin lead screw 203, a first slide rail 204, a first sliding frame 205, and a positioning gear 206. The two ends of the positioning pin lead screw 203 are respectively rotatably connected to the two ends of the first slide rail 204, and the positioning pin lead screw 203 is arranged parallel to the first slide rail 204. The first sliding frame 205 is movably sleeved on the positioning pin lead screw 203 and the first slide rail 204. The first sliding frame 205 is rotatably connected to the positioning pin lead screw 203, and the first sliding frame 205 is slidably connected to the first slide rail 204. The two ends of the positioning pin lead screw 203 are fixedly connected to the positioning gear 206. By driving the positioning gear 206 to rotate through a motor, the positioning pin lead screw 203 rotates, realizing the horizontal displacement of the first sliding frame 205 on the first slide rail 204. The positioning pin 201 is fixed to one side of the first sliding frame 205, that is, the horizontal displacement of the positioning pin 201 is realized, and the positioning of the positioning holes of silicon steel sheets with different sheet types is realized.

[0043] The positioning pin 201 has a three-lobe structure, and each lobe is provided with a magnet that attracts adjacent lobes to keep the positioning pin 201 in a closed state. During operation, the lower end of the positioning pin 201 is inserted into the positioning hole of the silicon steel sheet, and the positioning pin 201 opens to position the silicon steel sheet.

[0044] The utility model can remotely adjust the position of the positioning pin 201, has high positioning accuracy and high reliability, and can adapt to the hole distances of different sheet types; the positioning pin 201 has a three-lobe structure, which can effectively correct the sheet position and improve the lamination accuracy.

[0045] As Figure 7 shown, a pressure bar 207 is arranged on one side of the positioning pin 201. The pressure bar 207 is telescopically arranged on the first sliding frame 205. In this embodiment, the pressure bar 207 is driven by a cylinder, and the cylinder is fixed on the first sliding frame 205. After the positioning pin 201 is positioned, the silicon steel sheet to be positioned is first pressed tightly by the pressure bar 207, and then the positioning pin 201 is lifted. The pressure bar 207 helps the silicon steel sheet to maintain the correct position after the positioning pin 201 is disengaged by applying pressure, and can also prevent the displacement of the silicon steel sheet caused by other operations, thereby improving the lamination accuracy.

[0046] The positioning assembly 200 is arranged at the bottom of the side surface of the frame 110. As Figure 5 shown, both ends of the first slide rail 204 are fixedly connected to the frame 110.

[0047] The core yoke sheet translation manipulator of the utility model further includes a pressure feeding assembly 300.

[0048] As Figure 8 shown, the pressure feeding assembly 300 includes a pressure bar 301, a pressure feeding cylinder 302, a second sliding frame 303, and a second slide rail 304. When the large silicon steel sheet falls rapidly, it may cause other adjacent silicon steel sheets to be blown and displaced. The pressure feeding assembly 300 can fall to press the adjacent silicon steel sheets tightly.

[0049] The pressure feeding cylinder 302 drives the pressure bar 301 to expand and contract. The pressure feeding cylinder 302 is fixedly connected to the second sliding frame 303. The second sliding frame 303 is slidably connected to the second slide rail 304. The position of the second sliding frame 303 can be adjusted manually, or can also be driven by a lead screw or a rack and pinion. The pressure feeding assembly 300 can move to adapt to the pressure feeding of silicon steel sheets of different sheet types.

[0050] The pressure feeding assembly 300 is arranged at the bottom of the side surface of the frame 110. As Figure 5 shown, both ends of the second slide rail 304 are fixedly connected to the frame 110.

[0051] The working principle of the utility model is as follows:

[0052] First, manually adjust the position of the blanking component 300 in advance before the equipment operates. The yoke plates are conveyed to the receiving platform 600 by the belt conveyor 500. At this time, the core yoke plate translation manipulator of the present utility model moves above the receiving platform 600. The vacuum chuck 132 of the adsorption mechanism 130 first sucks up the middle part of the yoke plate. Immediately afterwards, the electromagnet 134 is energized to suck up the entire yoke plate. Then, the core yoke plate translation manipulator of the present utility model moves above the stacking platform 700. The blanking component 300 drops to press the adjacent silicon steel sheets. The electromagnet 134 is powered off, and the silicon steel sheets drop. The vacuum chuck 132 is ventilated, and the positioning pin 201 drops following the yoke plate. After dropping, the positioning pin 201 expands for positioning. The silicon steel sheet to be positioned is pressed by the pressing rod 207. Then, the positioning pin 201 is raised, and the core yoke plate translation manipulator moves to the initial position to complete the stacking of the upper yoke plate.

[0053] Among them, the belt conveyor 500 is a magnetic belt conveyor. The receiving platform 600 can receive the upper yoke plates that lose magnetism and fall on the conveyor belt 500 and rotate 90°. The conveyor belt 500, the receiving platform 600, and the stacking platform 700 are all conventional equipment on the existing market and will not be elaborated here.

[0054] The components and structures not described in detail in the embodiments belong to the well-known components, common structures, or common means in this industry and will not be described one by one here.
