Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a material preparation detection device for transformer core assembly. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface. The core and the coils wound on it form a complete electromagnetic induction system. The core is mostly IE-type silicon steel sheets stacked and fixed on a support frame. Therefore, when assembling the transformer, it is necessary to first separate the I-type part from the E-type, and then position the high-voltage winding and the low-voltage winding on the E-type silicon steel sheet, and then install the I-type silicon steel sheet on the E-type silicon steel sheet to complete the core assembly.

[0003] After searching, according to the Chinese invention patent application number CN202211560343.4, an automatic stacking and continuous loading and unloading device for transformer cores is proposed. The invention content records that "the present invention is equipped with a material taking manipulator, a stacking plate and a transmission plate. The outer wall of one side of the bracket is connected to the lifting silicon steel sheet warehouse. Traditionally, the material is taken directly through the lifting silicon steel sheet warehouse. Now, silicon steel sheets of different sheet widths are placed on the stacking plate and then put into the warehouse. The two silicon steel sheets of different sheet widths are automatically pulled from the warehouse to the material position of the bracket through the servo screw push-pull mechanism. After the stacking plate is in place, the material is taken through the material taking The suction cup of the robot picks up the silicon steel sheet and moves to the left to place the silicon steel sheet in the secondary shaping mechanism. For example, when thirty silicon steel sheets of one specification are taken to meet the number of sheets required, the material-retrieving robot moves directly to the top of the silicon steel sheet of another sheet width to directly retrieve the material again. At the same time, the silicon steel sheet of the original sheet width is pushed back to the original material warehouse through the servo screw push-pull mechanism, and then the stacking plate of the silicon steel sheet of the next sheet width specification in the material warehouse is pulled to the material position of the equipment. Waiting for the next material retrieval, this alternating repetition can achieve automatic loading of silicon steel sheets without stopping, thereby reducing pauses and speeding up the loading and unloading speed.

[0004] When the staff uses the automatic stacking and continuous loading and unloading device for the transformer core to load the silicon steel sheets, due to the improper operation of storing the silicon steel sheets in the early stage, it is inevitable that the silicon steel sheets with the same sheet width will be stored in different shapes. In the early preparation process, it is necessary to classify and collect the silicon steel sheets on the back in advance, or turn the silicon steel sheets on the back over so that the silicon steel sheets are in the same shape. Manual operation is time-consuming and labor-intensive, which reduces the preparation efficiency and affects the assembly speed of the transformer core. Therefore, a preparation detection device for transformer core assembly is proposed to solve the above problems. Summary of the invention
