Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a transformer lamination device. Background Art

[0002] Transformers are essential electrical equipment in power systems, used to change voltage levels to suit different applications. One of the core components of a transformer is the iron core (or magnetic core), which is typically made of multiple layers of thin silicon steel sheets or other high-permeability materials. High-frequency transformers, a type of transformer primarily used in high-frequency switching power supplies, are produced by stacking multiple silicon steel sheets in a molded cavity that mimics the shape of the sheets. Pressure is applied to lock the points between the sheets together, forming an iron core of a certain thickness. Pressing also ensures that the core is tightly packed and gapless, ensuring its integrity.

[0003] The invention with announcement number CN114203429B discloses an assembly equipment for the production of high-frequency electronic transformers. The equipment uses a pressing mechanism to press and a lifting mechanism to remove the iron core from the positioning groove, so as to solve the problem that the size of the stacked iron core is slightly different from that of the silicon steel sheet, causing the iron core to be easily stuck in the mold cavity and difficult to remove.

[0004] However, in the above scheme, the silicon steel sheets are placed manually, and each production requires the steps of jacking, manual removal, and then manual placement. On the one hand, the efficiency is low, and each placement of the silicon steel sheets requires manual quantification. On the other hand, when placed manually, the positioning groove is located below the pressing mechanism, which poses certain safety hazards. Utility Model Content

[0005] Based on the problems mentioned in the above background technology, the utility model provides a transformer lamination device.

[0006] The technical solution adopted by the utility model is as follows: a transformer lamination equipment, including a workbench, a quantitative mechanism and a discharging mechanism, the workbench is provided with a positioning groove, a pressing mechanism corresponding to the positioning groove is provided above the workbench, and an ejection mechanism is provided in the workbench corresponding to the positioning groove; the quantitative mechanism includes a discharge box arranged on the workbench, the discharge box includes a rectangular box surrounded by a first connecting plate and a second connecting plate respectively arranged opposite to each other, the two second connecting plates have mounting cavities on the opposite walls, an electromagnet is installed in the mounting cavity, and the bottom of the two first connecting plates has a discharge port; a first electric push rod is provided on the workbench, and a push block is connected to the output end of the first electric push rod, and the push block is used to push the silicon steel sheet from the discharge port to the positioning groove; the electromagnet is electrically connected to the first electric push rod, and the discharging mechanism is used to push the iron core out after ejection.

[0007] Furthermore, a guide groove is provided on the workbench, and the pusher block is slidably connected to the guide groove.

[0008] Furthermore, a cavity is formed at the bottom of the pusher block, and a sliding roller is provided in the cavity.

[0009] Furthermore, connecting blocks are provided at both ends of the first connecting plate close to one end of the first electric push rod, and connecting grooves matching the connecting blocks are provided on the two second connecting plates.

[0010] Furthermore, a cavity is provided at the bottom of the second connecting plate, and a transparent plate is arranged in the cavity.

[0011] Furthermore, the discharging mechanism includes a second electric push rod arranged on the workbench, and the second electric push rod is connected to a discharging block.

[0012] Beneficial effects of the utility model:

[0013] Through the setting of the quantitative mechanism, the discharge port of the discharge box determines each equal amount of discharge. Through the electrical connection between the electromagnet and the first electric push rod overall system, when the first electric push rod is working, the electromagnet generates magnetic force to adsorb the silicon steel sheet. The push block overcomes the magnetic force to push out a certain amount of silicon steel sheets, and the remaining silicon steel sheets are adsorbed by the electromagnet and will not slide down until the push block returns to its original position. The first electric push rod stops working, the electromagnet loses its magnetic force, and the upper silicon steel sheet falls to the surface of the workbench, waiting for the next equal amount to be pushed out, thereby realizing quantitative discharge without the need for tedious manual operation; the discharging mechanism pushes out the pressed and ejected iron core and enters the subsequent steps. The overall structure is simple, and automatic quantitative loading and discharging operations are realized with high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
