Description

Technical Field

[0001] This utility model relates to the technical field of motors, and specifically to an automatic adhesive printing device. Background Technology

[0002] For bonding motor insulation end plates, methods such as brushing, spraying, dipping, and rolling are generally used to evenly distribute the adhesive on the surface of the insulation end plate.

[0003] The brush coating method involves applying adhesive to the surface of the insulating end plate using a brush or paintbrush. To ensure a thorough and even coating, the adhesive needs to be spread evenly with a brush. The brush should be applied in one direction only, without back-and-forth motion, and at a relatively slow speed to avoid introducing air bubbles. The brush coating method has low production efficiency and poor working conditions.

[0004] Spraying is one method where adhesive is applied to the surface of the insulating end plate using a glue gun. Spraying is characterized by a uniform adhesive layer thickness, high production efficiency, and suitability for large-area bonding. However, it requires low-viscosity adhesive, resulting in a high content of volatile solvents, which pollutes the environment and poses safety risks. Furthermore, the non-adhesive-coated surfaces require protection, which is time-consuming and labor-intensive, making it unsuitable for small insulating end plates.

[0005] Dip coating is a process in which the insulating end plate is immersed in an adhesive solution or adhesive dispersion for coating. It is suitable for small, thin, and complex objects to be bonded, and its advantages include simple equipment, low adhesive consumption, and high production efficiency. However, it is not suitable for insulating end plates that require single-sided coating.

[0006] Among them, the roller coating method involves immersing a roller in the adhesive solution before transferring it to the surface to be bonded or coated. It is suitable for coating pressure-sensitive adhesives and hot melt adhesives. This method provides uniform coating, can be applied to single or double sides, and has high coating efficiency, making it suitable for continuous large-scale production. Its disadvantages are high equipment investment and the need for high output. Utility Model Content
