Description

Technical Field

[0001] This utility model relates to the field of post-processing technology for circuit board mounting, and in particular to a hanger for use after conformal coating. Background Technology

[0002] Conformal coating is a specially formulated protective coating mainly used to protect electronic circuit boards and related equipment from environmental corrosion. Its functions are not limited to the three basic functions of "moisture protection, salt spray protection, and mildew prevention", but also extend to multiple dimensions such as electrical performance optimization and mechanical protection.

[0003] Most conformal coatings are applied locally by dipping, while some are applied to entire panels. This latter method results in a large amount of conformal coating remaining on the panel after application. The panel is often placed vertically on a rack to allow the coating to dry and to prevent it from dripping onto other areas and polluting the environment. However, this current method is inconvenient for collecting the conformal coating, leading to some waste and increasing production costs for companies. Utility Model Content

[0004] This utility model provides a hanging rack for use after applying conformal coating, which solves the shortcomings of the prior art and facilitates the drying and collection of conformal coating, and has strong practicality.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0006] A hanger for use after applying conformal coating includes a bottom trough. A pair of inclined arms are welded to the bottom of the trough, and a surrounding plate is welded to the upper end of the inclined arms. The surrounding plate has a rectangular structure, and an inclined plate is welded to the surrounding plate. The upper end of the inclined plate extends outward at an angle, and multiple placement plates are welded to the inclined plate. There is a gap between the placement plate and the surrounding plate, and the end of the placement plate with the gap extends downward at an angle. After the control board is coated with conformal coating, it is placed on the placement plate. The inclined plate, after placement, supports the control board to prevent it from falling. The inclined placement plate also facilitates the dripping of conformal coating and subsequent collection operations.

[0007] The lower end of the enclosure is provided with an outlet, and a pair of inclined guide plates are provided at the outlet. The lower end of the inclined guide plates extends inward at an inclination, and the lower end of the inclined guide plates is bent into a vertical guide plate. The lower end of the vertical guide plate is provided with a collection box. The collection box facilitates the collection of conformal coating. In addition, the inclined guide plates facilitate the collection of conformal coating into the collection box.

[0008] Furthermore, a guide plate is welded to the lower end of the inclined plate. The guide plate is located directly below the gap between the placement plate and the surrounding plate. The inner end of the guide plate is located at the outlet. The inner end of the guide plate extends downward at an angle. The guide plate facilitates the introduction of the conformal coating to the outlet, preventing the conformal coating from accumulating at the lower end of the surrounding plate and affecting the collection of the conformal coating.

[0009] Furthermore, to facilitate the disassembly and installation of the collection box, a concave part is bent at the lower end of the vertical guide plate, and a pair of wing plates are provided at the upper end of the collection box, with the wing plates passing through the concave part.

[0010] Furthermore, to facilitate the removal of the collection box, a concave pull plate is welded to the upper end of the collection box.

[0011] Furthermore, to prevent the control board from shifting due to the tilted placement of the mounting plate, connecting posts are welded onto the inclined plate. These connecting posts correspond one-to-one with the mounting plates, with each post positioned above its corresponding mounting plate. To ensure the stability of the control board after placement and prevent it from tipping over, a spring pin is welded to the outer end of the connecting post. An outer disc is located at the outer end of the spring pin, and a spring is fitted onto the spring pin, positioned inside the outer disc. An inner pressure plate is fitted onto the spring pin, positioned inside the spring.

[0012] Furthermore, in order to prevent the inner pressure plate from limiting the control plates of different thicknesses, a rubber pad is provided on the inner wall of the inner end of the inner pressure plate.

[0013] Furthermore, to avoid rotation issues after the inner pressure plate is connected, the rod part of the spring pin is designed with a spline structure.

[0014] The advantages of the above technical solution are:

[0015] This invention facilitates the drying process after the entire board is impregnated with conformal coating, and also facilitates the collection of conformal coating for reuse, thereby reducing production costs. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0017] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0018] Figure 2 A magnified view of point A is shown. Detailed Implementation

[0019] like Figures 1-2As shown, a hanger for use after applying conformal coating includes a bottom groove 1, a pair of inclined arms 2 welded to the bottom of the bottom groove 1, a surrounding plate 3 welded to the upper end of the inclined arms 2, the surrounding plate 3 having a rectangular structure, and an inclined plate 30 welded to the surrounding plate 3, the upper end of the inclined plate 30 extending outward at an angle.

[0020] Multiple placement plates 31 are welded onto the inclined plate 30. There is a gap between the placement plate 31 and the surrounding plate 3, and the end of the placement plate 31 with the gap between it and the surrounding plate 3 extends downward at an angle.

[0021] The lower end of the enclosure 3 has an outlet, at which a pair of inclined guide plates 38 are provided. The lower ends of the inclined guide plates 38 extend inward at an incline. The lower ends of the inclined guide plates 38 are bent into vertical guide plates 39. The lower ends of the vertical guide plates 39 are provided with collection boxes 41. The upper ends of the collection boxes 41 are welded with concave pull plates 43. The lower ends of the vertical guide plates 39 are bent into concave parts 40. The upper ends of the collection boxes 41 are provided with a pair of wing plates 42, which pass through the concave parts 40. The lower ends of the inclined plates 30 are welded with guide plates 37. The guide plates 37 are located directly below the gap between the placement plate 31 and the enclosure 3. The inner end of the guide plates 37 is located at the outlet, and the inner end of the guide plates 37 extends downward at an incline.

[0022] A connecting post 32 is welded onto the inclined plate 30. The connecting post 32 and the placement plate 31 are in a one-to-one correspondence, and the connecting post 32 is located above the corresponding placement plate 31. A spring pin 33 is welded to the outer end of the connecting post 32. The outer end of the spring pin 33 is provided with an outer plate. Optionally, the rod part of the spring pin 33 has a spline structure. A spring 34 is sleeved on the spring pin 33. The spring 34 is located inside the outer plate. An inner pressure plate 35 is sleeved on the spring pin 33. The inner pressure plate 35 is located inside the spring 34. A rubber pad 36 is provided on the inner wall of the inner end of the inner pressure plate 35.

[0023] In this embodiment, during operation, the operator places the control board card, which is impregnated with conformal coating, on the placement plate 31. When placing the control board card, one side of the control board card is against the inclined plate 30, and the connecting column 32 limits one end of the control board card to ensure that the control board card is stably located on the placement plate 31. After the control board card is placed, the control board card also needs to be limited by the inner pressure plate 35 and the rubber pad 36 on it to prevent the control board card from falling off.

[0024] During the drying process, the dripping conformal coating flows along the inclined plate 30, the placement plate 31, and the guide plate 37 towards the outlet, and finally flows into the collection box 41. In addition, the operator needs to regularly empty and clean the conformal coating in the collection box 41.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
