Description

Technical Field

[0001] The utility model relates to the technical field of impedance iron core processing, in particular to a vacuum suction cup for an impedance iron core. Background Art

[0002] Impedance cores are an important component of resistors. They are prepared by arranging individual iron sheets neatly and then manually wrapping a marking tape around the neatly arranged iron sheets.

[0003] After the various sizes of core materials are transferred to the assembly line, the assemblers select the cores to be used according to the recipe. The cores are then arranged neatly, and a piece of Bakelite with glue evenly applied on both sides is inserted between the two cores. A press is then used to ensure that the multiple cores are glued together into a core group.

[0004] During the core assembly process, the core is often adsorbed, turned over, and other operations are often performed, which often require suction cups. The existing core operation suction cups have a single structure, and usually a single number of suction cups are used to adsorb the core, resulting in uneven adsorption force on the core, making the core adsorption unstable. In addition, for cores of different sizes, matching suction cups need to be set, which requires frequent adjustment and replacement of the suction cups, which is inconvenient to operate.

[0027] Analysis of the above content: When in use, the connecting base is connected to the driving mechanism through bolts and other structures. The driving mechanism is an existing hydraulic cylinder, servo slide, etc. The driving mechanism can perform operations such as horizontal and vertical movement of the installation base plate 1, side support plate 3, air pipe 5, vacuum control valve group, adsorption disc 7 and other structures through the connecting base. The air pipe 5, vacuum control valve group, and adsorption disc 7 are controlled based on the existing air supply circuit. When the impedance core needs to be adsorbed, the driving mechanism drives the installation base plate 1, side support plate 3, air pipe 5, vacuum control valve group, and adsorption disc 7 to descend and contact the corresponding impedance core. The adsorption disc 7 is vacuumed and adsorbed and fastened to the impedance core. Then the driving mechanism drives the entire body to move. When the position is reached, air is introduced into the adsorption disc 7 to separate the adsorption disc 7 from the impedance core.

The vacuum suction pump sucks the air in the air pipe 5 and the adsorption disc 7, so that the adsorption disc 7 is in a negative pressure state, and the iron core is adsorbed.
