[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] This embodiment provides an automatic production device for punching slots of stators and rotors, such as Figure 1-6 As shown, it includes an upper material handling mechanism 1, a first swing arm manipulator 2, a first punching machine 3, a second swing arm manipulator 4, a second punching machine 5 and a third swing arm manipulator 6 which are arranged in sequence. The upper material handling mechanism 1 is used for automatically loading and positioning blanks. The first swing arm manipulator 2 is used for carrying the blanks after positioning between the upper material handling mechanism 1 and the first punching machine 3. The first punching machine 3 is used for stator notching and punching the blanks. The second swing arm manipulator 4 is used for carrying the blanks after one processing between the first punching machine 3 and the second punching machine 5. The second punching machine 5 is used for rotor notching of the blanks after one processing to form products. The third swing arm manipulator 6 is used for unloading the products after processing by the second punching machine 5. This automated production device can achieve the production process without human intervention. One employee can operate two production lines and four punching machines at the same time.

[0028] Specifically, the upper material handling mechanism 1 includes a material pile platform, a sheet feeder 11 and a sheet sorter 12. The material pile platform is stacked with fallen sheets. The sheet sorter 12 is arranged on one side of the material pile platform. The sheet feeder 11 includes a first frame 111 and a material picking arm 112. The material picking arm 112 is arranged above the material pile platform and the sheet sorter 12 through the first frame 111. The material picking arm 112 is used to transfer the single fallen sheet from the material pile platform to the sheet sorter 12. The material picking arm 112 is provided with an electromagnetic induction sensor, and the sheet sorter 12 is used to position the fallen sheets.

[0029] The material suitable for the material pile platform is round sheet material with a material diameter of 800mm~1300mm, an axial hole in the center of the material, an axial hole diameter of 200mm-600mm, a thickness of 0.5mm silicon steel blanks, and a stacking height of 840mm (including the wooden support at the bottom of the pile of 120mm).

[0030] The lower limit of the up and down movement of the material picking arm 112 is 100mm away from the material pile platform, and the upper limit of the material picking must be larger than the working platform surface of the sheet sorter, and no collision should occur (the electromagnetic induction sensor is used to detect the falling pieces. When the material picking arm 112 reaches the top of the material pile, it automatically descends. When the electromagnetic induction sensor senses the signal sent by the iron material, the material picking arm 112 stops moving downward, the vacuum generator is activated to suck the falling pieces, and the material picking arm 112 moves upward to grab the falling pieces and transfer them to the sheet sorter 12. The material picking arm 112 includes a front and rear translation structure, an up and down translation structure and a material picking suction cup. The fixed end of the front and rear translation structure is connected to the first frame 111, the movable end of the front and rear translation structure is connected to the fixed end of the up and down translation structure, the movable end of the up and down translation structure is connected to the material picking suction cup, and the material picking suction cup is connected to the vacuum generator. The front and rear translation structure and the up and down translation structure can be existing electric linear slides, belt drive structures or chain drive structures.

[0031] In order to avoid taking out two sheets at the same time when the material taking arm 112 takes materials from the material pile, a magnetic divider 13 is required on the material pile platform. The magnetic divider 13 can be selected as model G3, and the number of magnetic dividers 13 is not less than 3 positions. At least 3 magnetic dividers 13 are provided on the material pile platform along the circumference of the material pile, and the magnetic divider 13 is rotated by a hinge connection.

[0032] Specifically, the sheet sorting machine 12 includes a second frame 121, a stripping plate 122, a positioning cylinder 123 and a central rotating assembly. The second frame 121 is arranged on the rear side of the material pile platform. Multiple positioning cylinders 123 are arranged on the upper surface of the second frame 121. The positioning cylinders 123 are used to position the outer circumferential surface of the blank. The central rotating assembly includes a turntable 124 and a central positioning frame 125. The turntable 124 is arranged in the middle of the upper surface of the second frame 121. The central positioning frame 125 is installed on the turntable 124 and moves up and down relative to the turntable 124. The central positioning frame 125 is used to center the axial hole of the blank. The stripping plate 122 is arranged on the upper surface of the second frame 121 and is located around the turntable 124.

[0033] Specifically, the center positioning frame 125 includes a rotating shaft 1251, a supporting plate and a mounting plate. The supporting plate is connected to the upper part of the rotating shaft 1251. The lower end of the rotating shaft 1251 is connected to a servo motor. The mounting plate is arranged above the supporting plate. The mounting plate extends the mounting frame outward in four directions in the same horizontal plane. The mounting frame is slidably connected with a center positioning part. A driving part for driving the center positioning part to slide is arranged between the supporting plate and the mounting plate. The driving part drives the center positioning part to slide to adjust the position of the center positioning part to adapt to the blanking sheet shaft holes of different sizes.

[0034] Specifically, the center positioning portion includes a guide rail 1252, a slider 1253, a positioning column sliding plate 1254, a positioning column fixing strip 1255 and a center positioning column 1256. The guide rail 1252 is arranged on the mounting frame, the positioning column fixing strip 1255 is installed on the slider 1253 through the positioning column sliding plate 1254, the slider 1253 is slidably connected to the guide rail 1252, and the center positioning column 1256 is arranged on the positioning column fixing strip 1255.

[0035] Specifically, the driving part includes an upper and lower pull block 1257, a positioning adjustment rod 1258 and an adjustment screw 1259. The upper and lower pull blocks 1257 are arranged on the upper surface of the support plate. One end of the positioning adjustment rod 1258 is hinged to the upper and lower pull blocks 1257, and the other end of the positioning adjustment rod 1258 is hinged to the positioning column sliding plate 1254. The adjustment screw 1259 passes through the mounting plate and is threadedly connected to the upper and lower pull blocks 1257. When the adjustment screw 1259 is turned, the rotation direction of the adjustment screw 1259 becomes larger or smaller, and the positioning column sliding plate 1254 is pulled to slide along the mounting frame by the upper and lower pull blocks 1257 and the positioning adjustment rod 1258, so as to adjust the positions of the central positioning column 1256 and the positioning column fixing strip 1255, which can meet the product requirements within the shaft hole diameter of 200mm-600mm. Optionally, the stripper plate 122 is provided with an electromagnet, which is used to attract the blanking piece; the shape of the electromagnet is to ensure that it can attract any shape of the product. Optionally, the center positioning frame 125 is also provided with a spring positioning pin, and as the center positioning frame 125 rotates, the spring positioning pin is engaged with the positioning hole of the blanking piece.

[0036] The wafer sorter 12 processes 0.5mm thick silicon steel blanks with an outer diameter of 800mm-1300mm and an axial hole diameter of 200mm-600mm. The picking arm 112 grabs the blanks and places them on the stripping plate 122. An electromagnetic induction sensor is installed on the upper surface of the second frame 121 of the wafer sorter 12. When a blank is detected, the positioning cylinders 123 around the wafer sorter 12 are actuated to push the blank for circumferential positioning. At the same time, the center positioning column 1256 at the center of the turntable 124 of the wafer sorter 12 is lifted up to adapt to the axial hole of the blank. The center positioning column 1256 centers the blank, and the center positioning of the blank on the wafer sorter 12 is completed. After that, the electromagnet installed on the stripping plate 122 is energized to suck the blanking piece, and after ensuring that the blanking piece does not rotate, the servo motor drives the center positioning frame 125 to rotate. When it rotates to the positioning hole of the blanking piece, the spring positioning pin installed on the center positioning frame 125 automatically pops up to pin the blanking piece. An electromagnetic induction sensor is also provided under the spring positioning pin. At this time, the electromagnetic sensor under the spring positioning pin detects that the spring positioning pin pops up, and sends a signal to cut off the power of the electromagnet. The center positioning frame 125 rotates under the drive of the servo motor. Since the spring positioning pin is pinned to the positioning hole of the blanking piece, the center positioning frame 125 drives the blanking piece to rotate together until it rotates to the set angle and stops. In this embodiment, the spring positioning pin is selected with a diameter of 6mm, and the specific size of the spring positioning pin can be selected and used according to the actual size of the positioning hole of the blanking piece.

[0037] Specifically, the first swing arm manipulator 2, the second swing arm manipulator 4 and the third swing arm manipulator 6 all adopt the existing relatively mature four-axis linkage manipulators, the first punch press 3 and the second punch press 5 are both servo punch presses, and the servo punch press and the four-axis linkage manipulator belong to the existing mature technology. The height requirement of the sheet sorting machine 12 is the same as the height of the lower die of the stamping die of the first punch press 3 (950mm in this embodiment), and the adjustment range is 900mm-1150mm. In order to adapt to production, a first material receiver 7 can be set at the second swing arm manipulator 4 to buffer the falling sheets after one processing, and a second material receiver 8 can be set at the third swing arm manipulator 6 to store the processed products.

[0038] The working process of this embodiment is as follows: the upper feeding mechanism 1 automatically feeds and positions the blanks, the first swing arm manipulator 2 transports the positioned blanks between the upper feeding mechanism 1 and the first punch press 3, the first punch press 3 performs stator notching and punching on the blanks, the second swing arm manipulator 4 transports the blanks that have been processed once between the first punch press 3 and the second punch press 5, the second punch press 5 performs rotor notching on the blanks that have been processed once to form products, and the third swing arm manipulator 6 unloads the products processed by the second punch press 5.

[0039] The advantages and positive effects of the present invention are as follows: the present invention provides an automated production device for stator and rotor slot punching, which completes automated control integration through the cooperation of the first swing arm manipulator, the second swing arm manipulator and the third swing arm manipulator 6 with the first punching machine and the second punching machine, so that the production process is unmanned. Except for loading and unloading material piles, changing molds and adjusting machines, the entire production line does not require manual intervention, thus saving manpower and improving production efficiency.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
