Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a dense immersion nozzle water jet. Background Art

[0002] In the process of producing printed circuit boards, printed circuit boards often need to undergo copper deposition, etching, development, chemical washing, water washing and drying in the production tank equipment; in the process of chemical washing or water washing, the circuit board generally needs the assistance of a water jet, and the process is as follows: the circuit board will be immersed in the tank, but because the holes of the circuit board are very small, it is not easy for the soaking water (chemical solution) to enter the holes of the circuit board, so a water jet is needed for spraying, and under the spraying pressure of the water jet, the water (chemical solution) can enter the holes of the circuit board; at present, the water outlet holes of the existing water jets are generally circular structures, and during the spraying process, only a water column structure (direct spraying) is formed, and there are gaps between adjacent water columns; the effect of cross-covering cannot be formed, so that the water (chemical solution) sprayed by the water jet cannot completely cover the circuit board, resulting in a lack of spraying pressure on some holes on the circuit board, making it difficult for water (chemical solution) to enter, thereby affecting the production quality of the circuit board; for this reason, we propose a dense immersion nozzle water jet. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a dense immersion nozzle water jet. After the improvement, the nozzle of the water jet has a fan-shaped structure, and the sprayed water or medicine can form a cross coverage, which will fully cover the holes on the circuit board without blind spots, so that the small holes on the circuit board can all enter the water or medicine, thereby ensuring the production quality of the circuit board.

[0004] The technical solution of the utility model is:

[0005] A dense immersion nozzle water jet comprises a water jet body and a nozzle;

[0006] The interior of the water jet body is a hollow structure, and a plurality of nozzles are provided at one end of the water jet body. The water outlets of the nozzles are fan-shaped structures so that water sprayed from adjacent nozzles forms a cross-coverage. A water spray channel is provided inside the nozzle, and the water spray channel is a structure that is larger inside and smaller outside.

[0007] Furthermore, the distance between adjacent nozzles is 15 mm.

[0008] Furthermore, a water jet connector is installed at one end of the water jet body.

[0009] Furthermore, a plug is installed at the other end of the water jet body.

[0010] Furthermore, a filter screen is installed inside the water jet joint.

[0012] The beneficial effects of the utility model are:

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-2 As shown,

[0019] A dense immersion nozzle water jet comprises a water jet body 1 and a nozzle 2; the water jet body 1 and the nozzle 2 are both made of plastic; the interior of the water jet body 1 is a hollow structure, the purpose is to facilitate water injection into the water jet body 1, and the water jet body 1 is a cylindrical structure; one end of the water jet body 1 is provided with a plurality of nozzles 2, and the plurality of nozzles 2 are arranged at equal intervals; the water outlet 3 of the nozzle 2 is a fan-shaped structure, so that the water sprayed between adjacent nozzles 2 forms a cross-coverage, it can be understood that the sprayed water will extend outward, the distance between the adjacent nozzles 2 spraying water is greater than the distance between the adjacent nozzles 2, and the water is sprayed and intersected; the interior of the nozzle 2 is provided with a water spray channel 4, the water spray channel 4 is a large inside and small outside structure; the structural setting of the water spray channel 4 increases the pressure of the water spray, which facilitates the water to enter the small holes on the circuit board.

[0020] As a preferred embodiment, the distance between adjacent nozzles 2 is 15 mm. The purpose of setting this distance is to make it easier for the sprayed water to form cross-coverage, thereby shortening the spray distance between the water jet and the circuit board. In the present application, the distance between the water jet and the circuit board can be 16 mm. At a shorter distance, the pressure of the water jet spray will be greater and the effect will be better.

[0021] As a preferred embodiment; a water jet connector 5 is installed at one end of the water jet body 1; it can be understood that the water jet connector 5 is detachably connected to the water jet body 1, the water jet body 1 is similar to a straight water pipe structure, the water jet connector 5 can be screwed and fixed to the water jet body 1, and can also be screwed and removed, and the use effect is better.

[0022] As a preferred embodiment, a plug 6 is installed at the other end of the water jet body 1. By providing the plug 6, the plug 6 and the water jet body 1 are also detachably connected. When the water jet is maintained and cleaned, the plug 6 can be removed to facilitate cleaning of the water jet.

[0023] As a preferred embodiment, a filter screen 7 is installed inside the water jet joint 5; the structure of the filter screen 7 is similar to the bag filter screen 7, but the material used is plastic, the purpose is to improve the filtering effect during the rapid water injection process.

[0024] The usage method and application scenario of the utility model are as follows: an external water pipe is connected to the water jet connector 5, so that water can be injected into the water jet body 1. Driven by the water pressure, water will be sprayed out from the nozzle 2. The shape of the water sprayed from the nozzle 2 is a fan-shaped water column, so that the water or medicine sprayed between adjacent nozzles 2 forms a cross-coverage; in addition, the water jet of the present application can be used in the process of chemical washing or water washing of the circuit board. The circuit board is transported to the water tank through the roller structure. The water or medicine in the water tank can soak the circuit board, and the water jet is arranged above and below the circuit board (in the water tank). The purpose is to perform double-sided spraying on the circuit board. It should be noted that the distance between the water jet nozzle 2 of the present application and the circuit board is 16 mm, so that the effect of chemical washing or water washing of the circuit board is better; when the water sprayed by the water jet fully covers the small holes of the circuit board, all the small holes on the circuit board are subjected to the spraying pressure, so that the water can enter the small holes of the circuit board.

[0025] It should be pointed out that the main problems in the prior art are: the water outlet holes of the existing water jet are generally circular structures, and during the jetting process, only a water column structure is formed, and there are gaps between adjacent water columns; the circuit board cannot be completely covered, resulting in a lack of jetting pressure in some holes on the circuit board, making it difficult for water to enter, thereby affecting the production quality of the circuit board;

[0026] Therefore, after the improvement of the present application, the water outlet 3 of the nozzle 2 is set to be a fan-shaped structure, and the water or medicine sprayed out is a fan-shaped water column, so that the water or medicine sprayed out between adjacent nozzles 2 forms a cross-coverage, which will fully cover the holes on the circuit board without blind spots. The holes on the circuit board can all be subjected to the spray pressure, so that the small holes on the circuit board can all enter the water or medicine, thereby ensuring the production quality of the circuit board.

[0027] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
