Automatic layer positioning device

Abstract

This invention belongs to the field of silicon steel sheet layer positioning technology, and particularly to an automatic layer positioning device. It includes two magnetic covers with a layering zone formed between them, an end positioning plate between the two magnetic covers, and an adsorption traction mechanism above the two magnetic covers. The positioning mechanism is installed through the magnetic covers. This invention positions stacked silicon steel sheet workpieces within the layering zone between the two magnetic covers. A magnetic field separates the stacked silicon steel sheet workpieces into layers. Then, through the cooperation of the positioning mechanism, the end positioning plate, and the adsorption traction mechanism, the position of the silicon steel sheet workpieces can be defined from three directions. This allows the gripping mechanism of the subsequent automatic stacking machine to accurately grip the silicon steel sheet workpiece at the target position, and the gripped position of the silicon steel sheet workpiece is consistent each time. Therefore, the automatic stacking machine does not need to readjust the position of the silicon steel sheet workpieces during subsequent stacking.

Description

Technical Field

[0001] This invention relates to the field of silicon steel sheet layer positioning technology, and more particularly to an automatic layer positioning device. Background Technology

[0002] In the transformer manufacturing industry, strip silicon steel sheets produced by shearing machines need to be precisely stacked in multiple layers to form complete unit blocks. Then, various silicon steel sheets are assembled using equipment (welding or riveting). An automatic silicon steel sheet stacking machine for transformer cores is an automated device used for efficient and precise stacking of silicon steel sheets, widely used in the manufacture of electromagnetic components such as transformers and motors. Its core objective is to achieve rapid, neat, and low-loss stacking of silicon steel sheets, ensuring optimal magnetic circuit performance of the core. The automatic stacking machine needs to pick up individual silicon steel sheets from a silo or conveyor belt.

[0003] However, since the silicon steel sheets in the material warehouse are stacked together, the gripping mechanism on the automatic stacking machine can easily lift the silicon steel sheets stuck to the bottom when it grabs the upper layer of silicon steel sheet workpieces. This causes the lower silicon steel sheet workpieces to be misaligned. When the gripping mechanism grabs the lower silicon steel sheet workpieces and feeds them into the automatic stacking machine for stacking, it is necessary to readjust the position of the misaligned silicon steel sheet workpieces again in order to achieve accurate stacking. Therefore, an automatic layer positioning device is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes an automatic layer positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic layered positioning device, comprising two magnetic covers, a layered area formed between the two magnetic covers, an end positioning plate provided between the two magnetic covers, and an adsorption traction mechanism provided above the two magnetic covers. A positioning mechanism is installed through the magnetic covers, the positioning mechanism comprising multiple cylinders spaced apart and multiple positioning columns two spaced apart. A positioning column one is fixedly installed at the end of the piston rod of each cylinder. After the stacked silicon steel sheet workpieces are layered in the layered area between the two magnetic covers, the two rows of positioning columns one limit the height of the uppermost silicon steel sheet workpiece, and the two rows of positioning columns two limit the left and right positions of the uppermost silicon steel sheet workpiece. The adsorption traction mechanism adsorbs and drags the uppermost silicon steel sheet workpiece to abut against the end positioning plate to limit the end position of the silicon steel sheet workpiece.

[0006] Preferably, the positioning mechanism includes a positioning strip fixed on the side of the magnet cover away from the end positioning plate. Multiple swing arms 1 are rotatably mounted on the top of the positioning strip. Each swing arm 1 passes through the magnet cover and is movably connected to the magnet cover. The side of each swing arm 1 near the layering area is fixedly connected to a corresponding cylinder. Multiple swing arms 2 are rotatably mounted on the bottom of the positioning strip. Each swing arm 2 passes through the magnet cover and is movably connected to the magnet cover. The side of each swing arm 2 near the layering area is rotatably connected to a corresponding positioning post 2.

[0007] Preferably, the magnet cover has multiple access ports 3 and 1 on the side near the layered area, and multiple access ports 2 on the side away from the layered area. Adjacent swing arms 1 and 2 pass through the same access port 2, and swing arms 1 and 2 located in the same access port 2 pass through the corresponding access ports 1 and 3 respectively.

[0008] Preferably, the positioning mechanism further includes an adjusting rod 1 and an adjusting rod 2 disposed on the side of the magnet cover away from the layered area. Multiple swing arms 1 are rotatably connected to the adjusting rod 1, and multiple swing arms 2 are rotatably connected to the adjusting rod 2. Mounting frames are fixedly installed at both ends of the magnet cover. L-shaped frames are fixedly installed on the mounting frames. One L-shaped frame is hinged to one end of the swing arm 2 with the same telescopic cylinder 1, and the other L-shaped frame is hinged to one end of the adjusting rod 1 with the same telescopic cylinder 2.

[0009] Preferably, the magnet cover is composed of multiple rectangular covers connected in sequence, with a partition plate between two rectangular covers, and adjacent access ports one, two and three are opened on the same rectangular cover.

[0010] Preferably, the end positioning plate is provided with a positioning protrusion.

[0011] Preferably, the adsorption traction mechanism includes a linear module disposed on one side of the two magnet covers. A movable frame is fixedly installed on the slider of the linear module, and a telescopic cylinder three is fixedly installed on the movable frame. The telescopic cylinder three is located directly above the layered area, and a vacuum suction cup is fixedly installed at the end of the piston rod of the telescopic cylinder three.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention places stacked silicon steel sheet workpieces within a layered area formed between two magnetic covers. The magnetic field separates the stacked silicon steel sheet workpieces into layers. Then, through the cooperation of a positioning mechanism, an end positioning plate, and an adsorption traction mechanism, the position of the silicon steel sheet workpieces can be defined from three directions. This allows the gripping mechanism of the subsequent automatic stacking machine to accurately grip the silicon steel sheet workpieces at the target position, and the position of the gripped silicon steel sheet workpieces is consistent each time. Therefore, the automatic stacking machine does not need to readjust the position of the silicon steel sheet workpieces when stacking them later. Attached Figure Description

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please refer to Figures 1-10 This invention provides a technical solution: an automatic layered positioning device, comprising two magnetic covers 1, a layered area 6 formed between the two magnetic covers 1, an end positioning plate 4 provided between the two magnetic covers 1, an adsorption traction mechanism 5 provided above the two magnetic covers 1, and a positioning mechanism 3 installed through the magnetic covers 1. The positioning mechanism 3 includes multiple cylinders 34 spaced apart and multiple positioning posts 36 spaced apart. A positioning post 35 is fixedly installed at the end of the piston rod of the cylinder 34. After the stacked silicon steel sheet workpieces are layered in the layered area 6 between the two magnetic covers 1, the two rows of positioning posts 35 limit the height of the uppermost silicon steel sheet workpiece, and the two rows of positioning posts 36 limit the left and right positions of the uppermost silicon steel sheet workpiece. The adsorption traction mechanism 5 adsorbs and drags the uppermost silicon steel sheet workpiece to abut against the end positioning plate 4 to limit the end position of the silicon steel sheet workpiece.

[0027] Furthermore, the magnet cover 1 is made of stainless steel. This device is located inside the automatic stacking machine. The magnetic field in the automatic stacking machine forms a non-uniform magnetic field in the layering zone 6. The magnetic field gradient force is used to separate the stacked silicon steel sheet workpieces in the layering zone 6. The stacked silicon steel sheet workpieces are usually subjected to the magnetic force of the magnetic field, the adhesive force of the adjacent silicon steel sheet workpieces below, and the gravity of the silicon steel sheet workpieces themselves.

[0028] Among them, the force on the top silicon steel sheet workpiece is Fmagnetic > Fadhesion + Fgravity, while the force on the adjacent lower silicon steel sheet workpiece is Fmagnetic < Fadhesion + Fgravity. Therefore, the top silicon steel sheet workpiece can be suspended.

[0029] The spacing between the two magnet covers 1 can be adjusted according to the different sizes of the silicon steel sheet workpiece.

[0030] The positioning mechanism 3 includes a positioning strip 31 fixed on the side of the magnet cover 1 away from the end positioning plate 4. Multiple swing arms 32 are rotatably mounted on the top of the positioning strip 31. The multiple swing arms 32 pass through the magnet cover 1 and are movably connected to the magnet cover 1. The side of the multiple swing arms 32 near the layering area 6 is fixedly connected to the corresponding cylinder 34. Multiple swing arms 33 are rotatably mounted on the bottom of the positioning strip 31. The multiple swing arms 33 pass through the magnet cover 1 and are movably connected to the magnet cover 1. The side of the multiple swing arms 33 near the layering area 6 is rotatably connected to the corresponding positioning post 36.

[0031] The magnet cover 1 has multiple access ports 3 14 and access port 12 on the side near the layered area 6, and multiple access ports 2 13 on the side away from the layered area 6. The adjacent swing arms 1 32 and swing arms 2 33 pass through the same access port 2 13, and the swing arms 1 32 and swing arms 2 33 located in the same access port 2 13 pass through the corresponding access ports 1 12 and access ports 3 14 respectively.

[0032] The positioning mechanism 3 also includes an adjustment rod 37 and an adjustment rod 38 disposed on the side of the magnet cover 1 away from the layered area 6. Multiple swing arms 32 are rotatably connected to the adjustment rod 37, and multiple swing arms 33 are rotatably connected to the adjustment rod 38. Mounting brackets 2 are fixedly installed at both ends of the magnet cover 1. An L-shaped frame 21 is fixedly installed on the mounting bracket 2. One L-shaped frame 21 is hinged to one end of the swing arm 33 with the same telescopic cylinder 39, and the other L-shaped frame 21 is hinged to one end of the adjustment rod 37 with the same telescopic cylinder 310.

[0033] Furthermore, such as Figures 9-7 As shown, by controlling the extension and retraction of the telescopic cylinder 39, multiple swing arms 33 can be driven to rotate synchronously around the positioning bar 31 via the adjusting rod 38;

[0034] By controlling the extension and retraction of the telescopic cylinder 310, multiple swing arms 32 can be driven to rotate synchronously around the positioning bar 31 via the adjusting rod 37.

[0035] The magnet cover 1 is composed of multiple rectangular covers 11 connected in sequence. A partition plate is provided between two rectangular covers 11, and adjacent access ports 12, 13 and 14 are opened on the same rectangular cover 11.

[0036] The end positioning plate 4 is provided with a positioning protrusion 41.

[0037] The adsorption traction mechanism 5 includes a linear module 51 disposed on one side of the two magnet covers 1. A movable frame 52 is fixedly installed on the slider of the linear module 51. A telescopic cylinder 53 is fixedly installed on the movable frame 52. The telescopic cylinder 53 is located directly above the layered area 6. A vacuum suction cup 54 is fixedly installed at the end of the piston rod of the telescopic cylinder 53.

[0038] Furthermore, before positioning, each positioning post 1 35 and positioning post 2 36 is located within its respective rectangular cover 11.

[0039] In this embodiment: When in use, the silicon steel sheet workpieces are stacked in the layered area 6. Under the action of the two magnet covers 1, the upper silicon steel sheet workpieces will be suspended. By controlling all the cylinders 34 on the two positioning mechanisms 3 to extend and retract synchronously, each positioning post 35 abuts against the top of the uppermost silicon steel sheet workpiece, thereby limiting the position and height of the uppermost silicon steel sheet workpiece.

[0040] Then, the positioning pins 36 on the two positioning mechanisms 3 are simultaneously extended into the layered area 6, and the two rows of positioning pins 36 abut against the left and right sides of the uppermost silicon steel sheet workpiece.

[0041] Then, the linear module 51 and the telescopic cylinder 53 drive the vacuum suction cup 54 to move back and forth and up and down, so that the vacuum suction cup 54 adsorbs the uppermost silicon steel sheet workpiece. Then, the linear module 51 drives the moving frame 52 to move, and the moving frame 52 drags the silicon steel sheet workpiece adsorbed below through the vacuum suction cup 54, and drags the silicon steel sheet workpiece so that its end abuts against the positioning protrusion 41.

[0042] The silicon steel sheet workpiece is positioned and its height is limited from above by two rows of positioning posts 35, and its front and rear positions are limited from the left and right sides by two rows of positioning posts 36. Finally, the end positioning plate 4 limits the end of the silicon steel sheet workpiece. By limiting the position of the silicon steel sheet workpiece from three directions, it is ensured that the silicon steel sheet workpiece can be accurately positioned at the target position. Then, the gripping mechanism on the automatic stacking machine can quickly and accurately grip the silicon steel sheet workpiece at the target position.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
