[0002] In the manufacturing process of printed circuit boards (PCBs), irradiation with a curing lamp in a UV curing unit is a common curing process, mainly used to cure UV-curable materials, such as UV-curable adhesives or UV-curable inks.

[0033] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0034] In this application, the term "parallel" includes not only absolute parallelism but also approximate parallelism as commonly understood in engineering. For example, "parallel" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between -1° and 1°. Similarly, "perpendicular" also includes not only absolute perpendicularity but also approximate perpendicularity as commonly understood in engineering. For example, "perpendicular" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between 89° and 91°. Equal distances or equal angles include not only absolute equality but also approximate equality as commonly understood in engineering, meaning there may be a certain degree of error, such as a tolerance range of -1% to 1%.

[0035] This application discloses a photocuring apparatus, which is a device that uses a light source of specific wavelength and intensity, such as ultraviolet (UV), to cure or harden certain materials. This technology is widely used in various fields, such as for curing protective coatings (e.g., conformal coatings) on PCBAs. This application embodiment uses the curing of a protective coating on a PCBA by a photocuring apparatus as an example for illustration.

[0036] The photocuring apparatus of this application embodiment has a conveying direction X, a first direction Y, and a second direction Z, wherein the conveying directions X, Y, and Z are perpendicular to each other.

[0037] Reference Figures 1 to 5As shown, the photocuring apparatus includes a main body 10, a curing lamp 20, a conveying assembly 30, a first refracting plate 40, and a second refracting plate 50. The main body 10 is connected to the curing lamp 20 and the conveying assembly 30, respectively, with the curing lamp 20 and the conveying assembly 30 spaced apart. The first refracting plate 40 and the second refracting plate 50 extend along the conveying direction X of the conveying assembly 30. In the first direction Y, the first refracting plate 40 is connected to one side of the conveying assembly 30, and the end of the first refracting plate 40 facing away from the conveying assembly 30 extends to one side of the curing lamp 20. The second refracting plate 50 is connected to the other side of the conveying assembly 30, and the end of the second refracting plate 50 facing away from the conveying assembly 30 extends to the other side of the curing lamp 20. The first refracting plate 40 and the second refracting plate 50 are used to reflect the light emitted by the curing lamp 20.

[0038] The main body 10 is used to install and support the curing lamp 20 and the conveying assembly 30. The main body 10 includes a bracket 12, a protective cover 11, support legs, and other structures.

[0039] In this embodiment of the application, in the height direction of the photocuring device, i.e. the second direction Z, the curing lamp 20 and the conveying component 30 are arranged at intervals. The interval between the curing lamp 20 and the conveying component 30 is used to set the first refracting plate 40 and the second refracting plate 50. The first refracting plate 40 and the second refracting plate 50 are used to reflect the light emitted by the curing lamp 20.

[0040] In the photocuring apparatus of this application embodiment, since the first refracting plate 40 and the second refracting plate 50 extend along the conveying direction X of the conveying assembly 30, and in the first direction Y, the first refracting plate 40 is connected to one side of the conveying assembly 30 and the second refracting plate 50 is connected to the other side of the conveying assembly 30, when the PCBA is on the conveying assembly 30, the PCBA can receive the light reflected from the first refracting plate 40 and the second refracting plate 50. The light reflected from the first refracting plate 40 and the second refracting plate 50 can illuminate the edge area of ​​the PCBA near the conveying assembly 30; and when there are tall components blocking the edge of the PCBA, the reflected light can also illuminate the blocked area. That is, the first refracting plate 40 and the second refracting plate 50 can reflect the light from the curing lamp 20 and concentrate it on the edge area of ​​the PCBA from both sides, increasing the energy density of the light in the edge area of ​​the PCBA. Therefore, in the photocuring device, the light reflected from the first refracting plate 40 and the second refracting plate 50 and the light emitted from the curing lamp 20 together irradiate the PCBA, which can irradiate the PCBA without dead angles and with uniform energy, so as to cure the protective coating on the PCBA, avoid the phenomenon of insufficient curing at the edges of the PCBA, improve the curing effect of the protective coating on the PCBA, and make the photocuring device have the advantage of high yield.

[0042] The photocuring apparatus of this application embodiment adjusts the distance between the first conveying component 31 and the second conveying component 32 using the adjusting component 60, enabling the photocuring apparatus to be compatible with PCBAs of different widths. Furthermore, the distance between the first refracting plate 40 and the second refracting plate 50 changes with the first conveying component 31 and the second conveying component 32, allowing the light reflected by the first refracting plate 40 and the second refracting plate 50 to adapt to PCBAs of different widths, achieving a better curing effect.

[0043] In some embodiments, a first blocking block 311 and a first conveying track 312 are sequentially arranged on the side of the first conveying component 31 facing the second conveying component 32, with at least a portion of the first blocking block 311 being higher than the first conveying track 312; a second blocking block 321 and a second conveying track 322 are sequentially arranged on the side of the second conveying component 32 facing the first conveying component 31, with at least a portion of the second blocking block 321 being higher than the second conveying track 322; the space enclosed by the first blocking block 311, the first conveying track 312, the second blocking block 321, and the second conveying track 322 is used to convey the part to be cured.

When the drive motor drives the lead screw 61 to rotate, the first support 65 and the second support 63 move closer to each other or further away from each other, thereby causing the first conveying component 31 and the second conveying component 32 to move closer to each other or further away from each other.

[0048] It is understood that two lead screws 61 can be provided, each connected to a first support 65 and a second support 63. Alternatively, at least two lead screws 61 can be provided, with at least two first supports 65 and at least two second supports 63, each lead screw 61 connected to one first support 65 and one second support 63.
