Description

Technical Field

[0001] The utility model relates to the technical field of electronic coil processing, in particular to an insulating layer coating device for electronic coils. Background Art

[0002] During the processing of electronic coils, it is necessary to first coat the surface of the coil's conductor with insulating material to form an insulating layer, thereby preventing the conductors from interfering with each other after the coil is wound.

[0003] Currently, the insulation coating of electronic coils is mostly done manually or semi-automatically, which is not only inefficient, but also difficult to precisely control during the manual coating process. This not only results in uneven coating, but also easily leads to different thicknesses of the insulation layer, affecting the insulation effect and overall performance of the electronic coils, and also causes serious waste of the insulation layer paint liquid.

[0004] To this end, we propose an insulation layer coating device for electronic coils to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an insulating layer coating device for electronic coils to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An insulating layer coating device for electronic coils includes a working box and a barrel. The wire inlet and wire outlet of the working box are both provided with a pair of upper and lower symmetrical guide wheels, and a coating barrel and a cooling barrel are sequentially provided in the working box from the wire inlet to the wire outlet. A liquid inlet pipe is connected to the outer wall of the coating barrel, and the liquid inlet pipe and the barrel are connected by a liquid guide pipe and a liquid suction pump. A scraper is installed at the outlet end of the coating barrel, and a cooling fan is connected to the outside of the cooling barrel through an air duct.

[0008] In a further embodiment, the working box consists of a coating box and a cooling box connected by a plurality of bolts, the coating cylinder is installed in the coating box, and the cooling cylinder is installed in the cooling box.

[0009] In a further embodiment, the scraper is connected to the side surface of the coating cylinder port by a plurality of bolts.

[0010] In a further embodiment, the inner diameter of the inlet end of the coating cylinder is smaller than the inner diameter of the outlet end.

[0011] In a further embodiment, the cooling cylinder adopts a double-layer hollow cylindrical structure, and a plurality of air holes are evenly provided on the surface of the inner shell of the cooling cylinder.

[0012] In a further embodiment, the liquid inlet pipes are symmetrically distributed above and below the coating cylinder, and the two liquid inlet pipes are connected to the liquid guide tube through a three-way joint.

[0013] In a further embodiment, the cooling fans are symmetrically distributed above and below the working box, and a filter is installed at the air inlet end of the cooling fan.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model transports the insulating layer paint liquid into the coating cylinder through the liquid inlet pipe. When the wire body of the electronic coil passes through the coating cylinder, the surface of the wire body is coated with the paint liquid. Under the restriction of the scraper, the excess paint liquid on the surface of the wire body can be scraped off, reducing the dripping situation, and the paint liquid coating is more uniform, so that the thickness of the insulating layer is kept consistent. At the same time, the cooling cylinder provided can quickly cool and shape the insulating layer, which is beneficial to improving the efficiency of the coating process of the insulating layer.

These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.

A liquid inlet pipe 6 is connected to the outer wall of the coating cylinder 4, and the liquid inlet pipe 6 is connected to the barrel 2 through a liquid guide pipe 7 and a liquid extraction pump 8. The barrel 2 is arranged on the side of the working box 1 to facilitate the extraction of the paint liquid in the barrel 2 into the coating cylinder 4, thereby coating the wire body. A scraper 41 is installed at the outlet end of the coating cylinder 4. The opening size of the scraper 41 limits the coating thickness of the insulating layer, so that excess paint liquid is blocked in the coating cylinder 4, and a cooling fan 10 is connected to the outside of the cooling cylinder 5 through an air duct 9.

[0028] See also Figure 4-5 In order to facilitate the adjustment of the coating thickness of the insulating layer, a scraper 41 is connected to the side of the coating cylinder 4 by several bolts to facilitate the replacement of the scraper 41. By controlling the opening size of the scraper 41, the amount of paint scraped off the surface of the conductor can be controlled.

[0029] See also Figure 5 In order to prevent the scraped paint liquid from overflowing from the inlet end of the coating cylinder 4, the inner diameter of the inlet end of the coating cylinder 4 is set to be smaller than the inner diameter of the outlet end, so that the inlet end of the coating cylinder 4 is high, thereby preventing the paint liquid from overflowing.
