Description

Apparatus of manufacturing adhesive type laminating core and method of using the same}

The present invention relates to an adhesive laminated core manufacturing apparatus. More specifically, when applying an adhesive to the lower part of a lamina member to manufacture an adhesive laminated core, the contact pressure between the lower end of the lamina member and the upper end of the adhesive pillar is uniformly applied. It relates to a controllable adhesive laminated core manufacturing device and a manufacturing method using the same.

In the conventional adhesive laminated core manufacturing device, there is a risk of adhesive leakage and surrounding contamination at the exit of the nozzle where the adhesive is applied, and the adhesive is exposed to the outside of the nozzle, causing the adhesive to constrict on the surface of the nozzle, resulting in blockage of the nozzle outlet and There are problems such as contamination, which can become a further problem in the trend of quantitative and precise dispensing of adhesives and shorter curing times.

In addition, the conventional adhesive laminated core manufacturing device has difficulty in applying a certain amount of adhesive to the surface of the steel sheet at regular intervals in conjunction with the blanking process, and requires precise control of the adhesive ejection amount and nozzle operation time (adhesive application timing). It is necessary to carefully manage the adhesive supply pressure, that is, the adhesive pressure inside the nozzle. If the adhesive application process is not performed properly, the layers of the laminated core are separated, leading to product defects, which leads to an increase in the defect rate, worsening productivity and increasing management costs. Problems such as this may result.

Prior Art 1 (Korean Patent Publication, KR10-2015-0136877) “Adhesive laminated core member manufacturing device and adhesive application unit” refers to an adhesive application unit being pressed by a lamina member so that the surface of the lamina member and the adhesive application unit, that is, the outlet of the nozzle, are pressed together. The adhesive is discharged by the pressure of the adhesive inside the nozzle only when it is in contact, and when the lamina member and the adhesive application unit separate, the outlet of the nozzle is blocked to prevent leakage of the adhesive.

However, in prior art 1, since the adhesive is discharged by opening and closing the nozzle, there is still a risk of the nozzle being clogged, and because pressure must be applied to discharge the adhesive into the nozzle at the correct timing, there was difficulty in controlling the discharge of the adhesive.

Prior Art 2 (Japanese Patent Publication No. 2003-033711) “Adhesive application device and adhesive application method” is not applied by an application roller, but is applied in the form of two or more point spots for one core material, which prevents staining. It is an invention that not only prevents the problem but also sufficiently reduces the consumption of adhesives. However, even in prior art 2, there is still a risk of the nozzle being clogged, and since the cylinder containing the piston is retracted by an external force and the adhesive is applied, control is difficult.
