Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and more particularly to an automatic lamination machine for main transformers. Background Technology

[0002] Currently, the stacking of main transformer cores in China is mainly done manually. The emergence of automated core stacking production lines has broken the traditional core manufacturing method. However, during automated core stacking, each silicon steel sheet needs to be precisely positioned to prevent inaccurate stacking of the main transformer cores in the next stacking process, which would affect the overall quality of the main transformer stacking.

[0003] Ensuring precise positioning of the main transformer core before automatic lamination becomes a crucial step in the automatic core lamination production line. Precise positioning of the upper and lower yoke silicon steel sheets and the silicon steel sheets of each core column is essential for the simultaneous lamination of each silicon steel sheet in the next step, ensuring accuracy. Therefore, current technology lacks a device for precise positioning of each silicon steel sheet in automatic transformer core lamination. To achieve precise positioning of each silicon steel sheet before core lamination, an automatic main transformer lamination machine is proposed. Summary of the Invention

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.

[0032] Please refer to Figures 1-9 This invention provides a technical solution: an automatic stacking machine for main transformers, comprising two horizontally and vertically arranged horizontal plates 1, with a mounting plate 3 below the horizontal plates 1. A lifting device 2 is provided between the horizontal plates 1 and the mounting plate 3, and the lifting device 2 is used to drive the mounting plate 3 to move up and down. Below the mounting plate 3 are a material-tapping opening and closing mechanism 4, a negative pressure adsorption component 5, and a magnetic adsorption positioning mechanism 6. The negative pressure adsorption component 5 performs negative pressure adsorption on the silicon steel sheet workpiece by moving up and down. After the adsorbed silicon steel sheet workpiece is transferred by the negative pressure adsorption component 5 to the magnetic adsorption positioning mechanism 6, the magnetic adsorption positioning mechanism 6 adsorbs the silicon steel sheet workpiece by magnetic force. The material-tapping opening and closing mechanism 4 is used to position the silicon steel sheet workpiece adsorbed by the magnetic adsorption positioning mechanism 6 left and right. The magnetic adsorption positioning mechanism 6 itself is also used to position the adsorbed silicon steel sheet workpiece front and back. A gantry frame 7 is provided below the horizontal plates 1, and the horizontal plates 1 are slidably mounted on the top of the gantry frame 7. The gantry frames 7 at the bottom of the two horizontal plates 1 are arranged in parallel, and both gantry frames 7 are slidably mounted on the ground rail 8.

[0033] Furthermore, the components below the two horizontal and vertically arranged horizontal plates 1 can be used to stack silicon steel sheet workpieces on the horizontal and vertical sides of the main transformer, respectively.

[0034] Furthermore, users can adjust the number of negative pressure adsorption components 5 and magnetic adsorption positioning mechanisms 6 according to actual production needs, thus making it suitable for gripping and positioning silicon steel sheet workpieces with longer positioning lengths.

[0035] The two horizontal and vertically arranged horizontal plates 1 can move in the XY direction at the top of the gantry 7, while the gantry 7 can move in the ZW direction.

[0036] The negative pressure adsorption assembly 5 includes a cross plate 51 installed below the mounting plate 3. The cross plate 51 and the mounting plate 3 are connected by a lifting mechanism 52. The lifting mechanism 52 is used to drive the cross plate 51 to move up and down. Two profiles 54 are installed at the bottom of the cross plate 51.

[0037] The second lifting mechanism 52 includes two internally threaded sleeves 521 that pass through the mounting plate 3 and are rotatably connected to the mounting plate 3. Each of the two internally threaded sleeves 521 is fixedly fitted with a pulley 524. Both pulleys 524 are located above the mounting plate 3. The second lifting mechanism 52 also includes a motor 523 fixed to the top of the mounting plate 3. A drive wheel is fixedly installed on the output shaft of the motor 523. The two pulleys 524 and the drive wheel are fitted with the same synchronous belt. A screw 522 is threadedly connected through the internally threaded sleeve 521. The bottom ends of the two screws 522 are fixedly connected to the top of the cross plate 51.

[0038] Furthermore, the drive wheel is driven to rotate by the motor 523, and the drive wheel then drives the two internal threaded sleeves 521 to rotate synchronously in the same direction via the synchronous belt, so that the two screws 522 can synchronously drive the cross plate 51 to move up and down.

[0039] The magnetic adsorption positioning mechanism 6 includes two belts 61 and two belts 62 rotatably mounted below the mounting plate 3. The two belts 62 are located between the two belts 61. The position of the two belts 62 below the mounting plate 3 remains unchanged. The two belts 61 can move horizontally synchronously below the mounting plate 3, and the moving directions of the two belts 61 are opposite.

[0040] Furthermore, the two belts 262 are located between the two profiles 354.

[0041] Both belt 1 61 are equipped with magnet frame 1 63 inside, and both belt 2 62 are equipped with magnet frame 2 64 inside. The two magnet frames 1 63 and the two magnet frames 2 64 can move up and down synchronously, and the two magnet frames 1 63 can move horizontally synchronously below the mounting plate 3 following the corresponding belt 1 61.

[0042] The magnetic adsorption positioning mechanism 6 also includes a second moving mechanism 65 and a third lifting mechanism 66. The second moving mechanism 65 includes two wheel frames 651 fixed to the bottom of the mounting plate 3, and two belts 62 rotatably disposed between the two wheel frames 651. The second moving mechanism 65 also includes two long plates 654 slidably mounted on the top of the mounting plate 3. The two ends of the two long plates 654 are fixedly mounted with moving frames 653, and the bottom of the moving frames 653 is fixedly mounted with wheel frames 652. The wheel frames 652 pass through the mounting plate 3 and are slidably connected to the mounting plate 3. The two belts 61 are rotatably disposed in the corresponding wheel frames 652. The second moving mechanism 65 also includes a second lead screw 655 rotatably disposed on the top of the mounting plate 3. The second lead screw 655 is provided with two threads with opposite directions of rotation, and the two long plates 654 are respectively adapted to the threads with corresponding directions of rotation.

[0043] The lifting mechanism 366 includes four cylinders 2663 arranged in a rectangular shape. All four cylinders 2663 pass through the mounting plate 3 and are slidably connected to the mounting plate 3. Two cylinders 2663 located on the same side are fixedly connected to the same long plate 654. L-shaped brackets 661 are fixedly installed at the piston rod ends of all four cylinders 2663. The bottom ends of the two L-shaped brackets 661 located on the same side are fixedly connected to the top of the same magnet bracket 163. The lifting mechanism 366 also includes two cylinders 364 that pass through the mounting plate 3 and are fixedly connected to the mounting plate 3. T-shaped brackets 662 are fixedly installed at the piston rod ends of the two cylinders 364. The bottom ends of the two T-shaped brackets 662 are fixedly connected to the top of the two magnet brackets 264.

[0044] Furthermore, the two belts 61 on the magnetic adsorption positioning mechanism 6 are respectively adapted to the two adsorption mechanisms 53. The profile 531 on the adsorption mechanism 53 is located on one side of the belt 61, and the two profiles 532 are located on the other side of the belt 61. The two adsorption mechanisms 53 and the corresponding belts 61 can move left and right synchronously in the same direction, and the adsorption mechanism 53 can also move up and down independently.

[0045] Furthermore, the second lead screw 655 is driven by a motor. If the number of magnetic adsorption positioning mechanisms 6 is increased, all the second lead screws 655 will rotate synchronously.

[0046] The material-tapping opening and closing mechanism 4 includes two lifting mechanisms 41 located below the mounting plate 3. Each of the two lifting mechanisms 41 is equipped with a tapping rod 43. The material-tapping opening and closing mechanism 4 also includes multiple moving mechanisms 42 that are evenly distributed on the top of the mounting plate 3. The multiple moving mechanisms 42 that move synchronously are used to drive the two lifting mechanisms 41 to move synchronously, and the two lifting mechanisms 41 move in opposite directions.

[0047] The material-tapping opening and closing mechanism 4 includes multiple movable plates 411 that are slidably installed at equal intervals on the bottom of the mounting plate 3. A cylinder 412 is fixedly installed on the movable plate 411, and the piston rod end of the cylinder 412 is fixedly connected to the corresponding tapping rod 43.

[0048] The moving mechanism 42 includes a lead screw 421 rotatably mounted above the mounting plate 3. The lead screws 421 on the multiple moving mechanisms 42 rotate synchronously. Two moving frames 422 are threaded on the lead screw 421. The two moving frames 422 pass through the mounting plate 3 and are fixedly connected to the corresponding moving plate 411. The lead screw 421 is provided with two sections of threads with opposite directions of rotation. The two sections of threads with opposite directions of rotation are respectively adapted to the corresponding moving frames 422.

[0049] Furthermore, all lead screws 421 on the multiple moving mechanisms 42 rotate synchronously in the same direction. Each lead screw 421 can be driven independently by a motor, or a single motor can be used to drive each lead screw 421 synchronously in the same direction through gear transmission.

[0050] In this embodiment: when used, as follows Figure 1 , Figure 3 As shown, the mounting plate 3 is first moved above the silicon steel sheet workpiece to be gripped. Then, the lifting device 2 drives the mounting plate 3 to move down, so that the corresponding suction cups 533 and 55 of the negative pressure adsorption component 5 are in close contact with the top of the silicon steel sheet workpiece and perform negative pressure adsorption on the silicon steel sheet workpiece. Then, the lifting mechanism 52 drives the cross plate 51 to move up, and the cross plate 51 then drives the silicon steel sheet workpiece below to move up. When the silicon steel sheet workpiece moves up and is in contact with the corresponding belts 61 and 62, the lifting mechanism 52 no longer drives the silicon steel sheet workpiece to move up.

[0051] like Figure 1 , Figures 4-5 As shown, as the silicon steel sheet workpiece comes into contact with the corresponding belt 61 and belt 62, the lifting mechanism 66 controls all the magnet frames 63 and 64 to move down. When the magnet frame 63 moves down and comes into contact with the lower half of belt 61 and the magnet frame 64 moves down and comes into contact with the lower half of belt 62, the magnet frame 63 will provide magnetic attraction to the silicon steel sheet workpiece below through belt 61 and the magnet frame 64 through belt 62, so that the silicon steel sheet workpiece is magnetically attracted to the bottom of the corresponding belt 61 and belt 62.

[0052] Then the negative pressure adsorption component 5 can be released from the negative pressure adsorption of the silicon steel sheet workpiece, and the cross plate 51 can be driven to move upward, so that the silicon steel sheet workpiece is attached to the bottom of the corresponding belt 61 and belt 62 by the magnetic attraction of the corresponding magnet frame 63 and magnet frame 64, and at this time the silicon steel sheet workpiece is between the two lifting mechanisms 41.

[0053] like Figures 1-2 , Figures 4-6 As shown, for a silicon steel sheet workpiece located between two lifting mechanisms 41, multiple moving mechanisms 42 can drive the two lifting mechanisms 41 to move the two levers 43 closer to each other. The two levers 43 push the silicon steel sheet workpiece from the left and right sides respectively, so that the silicon steel sheet workpiece can slide at the bottom of the corresponding belts 61 and 62, thereby completing the coarse positioning of the silicon steel sheet workpiece on the left and right sides. After the silicon steel sheet workpiece completes the coarse positioning in the left and right directions, a certain gap is maintained between the silicon steel sheet workpiece and the two levers 43.

[0054] like Figures 1-2 , Figures 4-5As shown, the two belts 61 and 62 on the magnetic adsorption positioning mechanism 6 are then controlled to rotate synchronously in the same direction, thereby driving the silicon steel sheet workpiece at the bottom to move in the front and back direction. By installing positioning blocks suitable for the shape of the front and back ends of the silicon steel sheet workpiece at the bottom of the mounting plate 3, when the silicon steel sheet workpiece moves back and forth and the end abuts against the corresponding positioning block, the precise positioning of the silicon steel sheet workpiece in the front and back direction is completed.

[0055] like Figures 1-2 , Figures 4-6 As shown, after the front-back direction of the silicon steel sheet workpiece is accurately positioned, the left-right direction of the silicon steel sheet workpiece is then accurately positioned by the two levers 43. At this point, the accurate positioning of the front-back and left-right directions of the silicon steel sheet workpiece is completed.

[0056] like Figure 9 As shown, after the precise positioning of the silicon steel sheet workpiece located under the mounting plate 3 in the front-back direction and left-right direction is completed, the silicon steel sheet workpiece located under the mounting plate 3 can be moved to the target position for orderly and precise stacking by the cooperation of the gantry 7 and the ground rail 8.

[0057] like Figure 1 , Figures 4-5 As shown, when stacking silicon steel sheet workpieces, all magnet frames 1 63 and magnet frame 2 64 are moved upward by lifting mechanism 3 66. As magnet frames 1 63 and magnet frame 2 64 move upward and the distance between them and the bottom increases, the magnetic attraction force on the silicon steel sheet workpieces will decrease. Then, the silicon steel sheet workpieces will separate from the corresponding belts 1 61 and 2 62 under the action of gravity and fall. The precisely positioned silicon steel sheet workpieces will be stacked on the target workstation after falling.

[0058] 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.
