[0002] When manufacturing a PCB board, a screen is usually required for solder mask printing and text printing. The screen is generally prepared through the following steps: first, draw a pattern on a film negative, then expose the screen through the pattern on the film negative, and finally develop the exposed screen.
[0003] When developing a screen in the prior art, generally one end of a hose is connected to a faucet, and then the front end of the hose is held by hand to rinse the screen. The surface of the screen is coated with a photosensitive glue. Based on the pattern of the film negative, the surface of the screen will be divided into a large number of exposed areas and light-shielding areas; the photosensitive glue in the exposed areas has been photocured and will not be washed away by water; the photosensitive glue in the light-shielding areas will be washed away by water; in this way, the development can be completed to obtain a patterned screen.
[0004] Due to the lack of a dedicated developing and rinsing device, the above-mentioned developing method has the following problems in the operation process: 1. The staff needs to hold the screen with one hand and hold the hose to rinse with the other hand, which is very inconvenient to operate and the water splashes everywhere. 2. When rinsing, the staff needs to hold up the screen against the light to check; if it is found that the pattern on the screen is not rinsed clean, then put down the screen and continue to rinse; the whole inspection process is very troublesome.

[0028] The following is combined with the attached Figure 1 ~Attached Figure 2A detailed description is given of the embodiments of the present utility model.
[0029] An embodiment of the present utility model provides a developing and rinsing device for a PCB printing screen. The developing and rinsing device includes: a rinsing table 1. The rinsing table 1 is provided with a left side plate 2, a right side plate 3, and a rear side plate extending upward to block splashing water. It should be understood that the left side plate 2, the rear side plate, and the right side plate 3 are connected in sequence as a whole. A water blocking strip 4 is provided on the front side of the rinsing table 1 to cooperate with the left side plate 2, the right side plate 3, and the rear side plate to form a confluence pool. The confluence pool is provided with a drain port 5 to communicate with a drain pipe. A window 6 is provided on the rear side plate, and a baffle made of a transparent material is installed in the window 6. It should be understood that the transparent material for making the baffle can be selected from glass or transparent plastic. A detection lamp 7 is provided on the rear side of the baffle. It should be understood that the detection lamp 7 is usually selected as a strip-shaped or plate-shaped lamp, so that the light can be more uniform.
[0030] The following describes the specific implementation manner of the present utility model: Stand the screen on the rinsing table 1, make the screen close to the rear side plate, and make the surface to be rinsed of the screen face forward; turn on the detection lamp 7, and connect the hose 18 to the water source, then the staff can hold the hose 18 to rinse the screen. The left side plate 2, the right side plate 3, and the rear side plate surrounding the rinsing table 1 can not only prevent water splashing out, but also block the external light, making the area where the screen is located darker. In this way, with the irradiation of the rear detection lamp 7, it can be checked whether the screen is rinsed clean. The present utility model not only facilitates the staff to rinse the screen, but also facilitates the staff to check the screen, and has the value of popularization and use.
[0031] Furthermore, it further includes: a top plate 8 extending forward from the top of the rear side plate; the front-back width of the top plate 8 is smaller than the front-back width of the left side plate 2, the right side plate 3, and the rinsing table 1 to form a rinsing area at the rear section of the rinsing table 1. It should be understood that the top plate 8 can block the external light, making the rinsing area darker, so as to facilitate the staff to check the screen through the irradiation of the rear detection lamp 7.
[0032] Furthermore, a light shielding strip 9 is provided on the front side edge of the top plate 8 extending downward. It should be understood that the light shielding strip 9 can block the external light, making the rinsing area darker, so as to facilitate the staff to check the screen through the irradiation of the rear detection lamp 7.
[0033] Furthermore, a lamp shade is installed on the rear side of the rear side plate, and the detection lamp 7 is installed in the lamp shade. It should be understood that the lamp shade can block the external dust and prevent the brightness of the detection lamp 7 from decreasing due to dust accumulation.
[0034] Further, it also includes: a bracket 10; the bracket 10 includes: a cross-frame 11 for placing the screen punching table 1, and vertical frames 12 located on both sides of the cross-frame 11 and supporting it; the cross-frame 11 is provided with holes for the drain pipe to pass through. It should be understood that the cross-frame 11 and the vertical frames 12 can be arranged in a plate shape or a grid shape.
[0035] Further, the bracket 10 also includes: a first reinforcing plate 13 and a second reinforcing plate 14; the first reinforcing plate 13 is vertically arranged and connected to the rear side edges of the cross-frame 11 and the two vertical frames 12; the second reinforcing plate 14 is horizontally arranged, and its two ends are respectively connected to the two vertical frames 12. It should be understood that the second reinforcing plate 14 can also serve as a placement table for placing related items for rinsing the screen plate.
[0036] Further, it also includes: a high-pressure water gun; the high-pressure water gun is connected to a water source through a hose 18. It should be understood that the water pressure of tap water is unstable and it is easy to have a situation where the water pressure is insufficient; this will cause the photosensitive glue in the light-shielding area of the screen plate not to be rinsed clean, resulting in the screen plate not being oiled during subsequent screen printing, and further causing product rework or scrapping. By using a high-pressure water gun, it can be ensured that the photosensitive glue in the light-shielding area of the screen plate is rinsed clean. The water source generally refers to the tap water pipe network.
[0037] Further, a connecting pipe 15 is installed on the right side of the right side plate 3; the rear end of the connecting pipe 15 is connected to the water source and the front end is connected to the hose 18. It should be understood that the connecting pipe 15 can also be installed on the left side of the left side plate 2, and a pipe hole 16 is provided in the upper front part of the left side plate 2. The rear end of the connecting pipe 15 is generally connected to the water source through a rubber pipe.
[0038] Further, a pipe hole 16 is provided in the upper front part of the right side plate 3 for the hose 18 to pass through. It should be understood that by setting the pipe hole 16 to restrict the hose 18, the hose 18 can be stored more conveniently and neatly.
