Description

Technical Field

[0001] This utility model relates to the field of photocuring technology, specifically to a photocuring device for electromagnetic wire insulating varnish. Background Technology

[0002] The quality of the insulation varnish curing process of reactors directly affects the product quality and the cost required for safety and environmental protection. Existing insulation varnishes cannot accurately control the thickness of the varnish during the spraying process, which can lead to situations where the thick varnish cannot be effectively cured after the wire harness is exposed to ultraviolet light. Utility Model Content

[0003] The purpose of this invention is to provide a device for curing electromagnetic wire insulating varnish, which forcibly corrects the thickness of the varnish film after spraying through the dual action of mechanical scraping and elastic extrusion, so that it reaches a uniform state before curing without damaging the wire harness conductor, thus solving the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic wire insulating varnish light curing device, comprising a main body and a wire harness, wherein a spraying unit is provided above one end of the main body and an ultraviolet curing box is provided above the other end of the main body, wherein a leveling unit is provided inside the ultraviolet curing box, and a dust removal fan is provided below the spraying unit and the ultraviolet curing box.

[0005] Preferably, the leveling unit includes a vertical track frame, a conduit shaft, and a horizontal coupling, wherein the horizontal coupling is slidably connected to the vertical track frame, and the vertical track frame is connected to the main body of the chassis by screws.

[0006] Preferably, the threading tube shafts are arranged horizontally inside the horizontal coupling, and the threading tube shafts are connected to the horizontal coupling by screws.

[0007] Preferably, the inside of the threading tube shaft is provided with a wire cavity, and four sets of rubber rollers are provided around the wire cavity, wherein the outer surface of the rubber rollers is provided with a sponge sleeve.

[0008] Preferably, the outer surface of the threading tube shaft is provided with a scraping groove, which extends through to the surface of the rubber roller.

[0009] Preferably, the inner side of the ultraviolet curing chamber is provided with a ring lamp tube, and both ends of the ring lamp tube are provided with light shields.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, when the wire harness passes through the central cavity, the rotating roller rotates in close contact with the paint surface with elastic pressure, and the scraper groove penetrates to the surface of the rotating roller to form a continuous annular scraper blade. When the rotating roller moves and rotates with the wire harness, the scraper groove scrapes off excess paint with controllable pressure, while the sponge sleeve absorbs the overflow paint. Through the dual action of mechanical scraping and elastic extrusion, the thickness of the paint film after spraying is forcibly corrected so that it reaches a uniform state before curing, without damaging the wire harness conductor.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To address the issue that existing insulating varnishes cannot precisely control their thickness during spraying, which leads to ineffective curing of thicker varnish layers after UV exposure; please refer to... Figure 1-4 The present invention provides the following solution:

[0019] refer to Figure 1-4An electromagnetic wire insulating varnish UV curing device includes a main body 1 and a wire harness 4. A spraying unit 2 is arranged above one end of the main body 1, and an ultraviolet curing box 3 is arranged above the other end of the main body 1. A leveling unit 6 is arranged inside the ultraviolet curing box 3. A dust removal fan 5 is arranged below the spraying unit 2 and the ultraviolet curing box 3. An annular lamp tube 301 is arranged inside the ultraviolet curing box 3, and a light shield 302 is arranged at both ends of the annular lamp tube 301.

[0020] In this embodiment, the wiring harness 4 enters from the inlet end of the main body 1 of the chassis, and ascends to the spraying unit 2, where it is evenly covered with insulating varnish by the atomizing nozzle. The spraying unit adopts closed-loop control, which can dynamically control the amount of varnish output per unit time, thus initially ensuring the uniformity of the varnish film. The fan is located between the spraying unit 2 and the ultraviolet curing chamber 3, and removes excess varnish from the inside of the chamber through negative pressure adsorption or directional airflow.

[0021] refer to Figure 2-3 The leveling unit 6 includes a vertical track shaft 601, a cable guide shaft 602, and a horizontal coupling 603. The horizontal coupling 603 is slidably connected to the vertical track shaft 601, and the vertical track shaft 601 is connected to the main body 1 of the housing by screws. The cable guide shafts 602 are arranged horizontally inside the horizontal coupling 603 and are connected to the horizontal coupling 603 by screws. The cable guide shaft 602 has a cable cavity 6021 inside, and four sets of rubber rollers 6022 are arranged around the cable cavity 6021. The outer surface of the rubber rollers 6022 is provided with a sponge sleeve, and the outer surface of the cable guide shaft 602 is provided with a scraping groove 6023, which extends through to the surface of the rubber rollers 6022.

[0022] In this embodiment, before the wire harness enters the UV curing chamber 3, it first passes through the leveling unit 6. Four sets of rubber rollers 6022 with sponge sleeves are embedded in the wire tube shaft 602. When the wire harness passes through the wire cavity 6021 in the center, the rollers rotate tightly against the paint surface with elastic pressure. The scraping groove 6023 penetrates to the surface of the rollers to form a continuous annular scraping blade. When the rollers move and rotate with the wire harness, the scraping groove scrapes off excess paint with controllable pressure. At the same time, the sponge sleeve absorbs the overflow paint to avoid secondary accumulation.
