[0002] The surface of the electroplated electronic product (continuous PIN terminal material belt) will form a layer of metal film, which has good conductivity and can ensure the stability and accuracy of electronic signal transmission. After surface electroplating, the electronic product usually needs to be covered with a layer of oily hole sealing agent on the product surface. The hole sealing oil agent can fill the pores and defects in the electroplated layer, making the electroplated layer more uniform and smooth, thereby achieving better corrosion protection effect.

[0003] The common oil sealing process has full immersion type and direct spraying type. The full immersion type is to immerse the entire product in the hole sealing agent.

The direct spraying type is to atomize the hole sealing agent through the spray head. The atomized hole sealing agent finally adheres to the product surface to achieve the purpose of hole sealing. However, the atomization effect of the oily hole sealing agent is related to the structure of the spray head. If the oily hole sealing agent is not completely atomized, it will form a point-shaped liquid oily hole sealing agent on the product surface, forming an oil spot, which not only causes the oily hole sealing agent on the product surface to be unevenly covered, but also causes the product surface to be easy to get dust in the later stage, thereby affecting the appearance.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of this utility model, a nozzle is disclosed for reducing the content of dotted liquid oil in the atomized oily sealant and spraying the atomized oily sealant to adhere to the surface of the material belt 6. The nozzle includes...

[0030] The nozzle body 1 has a hollow cavity 16 with openings at both ends. The openings include an inlet 111 and an outlet 141. The inlet 111 is connected to an atomizer 5 that sprays atomized oily sealing agent via a pipe. After passing through the hollow cavity 16, the atomized oily sealing agent is sprayed out from the outlet 141. The hollow cavity 16 has at least two baffles 15, and can also have four or six baffles as needed. The two baffles 15 are arranged parallel to each other, spaced apart, and staggered on the upper and lower inner walls of the hollow cavity 16. The two baffles 15 and the hollow cavity 16... An S-shaped channel is formed between the inner walls of the material belt 6. When the atomized oily sealant passes through the S-shaped channel quickly, the dotted liquid oil in the atomized oily sealant will collide with the surface of the baffle 15 and the inner wall of the hollow cavity 16 due to factors such as weight and volume, and finally converge at the bottom of the S-shaped channel. The atomized oily sealant, due to its small volume and weight, passes through the S-shaped channel smoothly and is finally sprayed out from another outlet 141. The sealant adheres to the surface of the material belt 6 to form a uniform oily sealant protective film, which greatly reduces the oil spots on the surface of the material belt 6 and improves the problem of dust easily sticking to the surface of the material belt 6.

[0031] Furthermore, a discharge hole is provided at the bottom of the S-shaped channel, through which the oily sealing agent that has accumulated at the bottom of the S-shaped channel can be discharged. During operation, the discharge hole is sealed by a sealing element.

[0032] Reference Figure 1 As shown, further, in order to facilitate the machining of an S-shaped channel within the nozzle body 1, the nozzle body 1 is configured as a split structure composed of multiple parallel and closely arranged splicing plates. The splicing plates are preferably made of stainless steel. The discharge port and through holes of different sizes and shapes can be milled separately on each splicing plate first, and then the multiple splicing plates are welded together. The through holes of the multiple splicing plates are interconnected and together form the S-shaped channel. The baffle 15 mentioned above can be regarded as part of the splicing plate.

[0033] Reference Figure 1 As shown, further, the plurality of splicing plates include a first splicing plate 11 with the feed inlet 111, a second splicing plate 12 with the first through hole 121, a third splicing plate 13 with the second through hole 131, and a fourth splicing plate 14 with the discharge outlet 141. The outer contours of the first splicing plate 11, the second splicing plate 12, the third splicing plate 13, and the fourth splicing plate 14 are all the same and flush with each other. The second splicing plate 12 and the third splicing plate 13 are alternately arranged between the first splicing plate 11 and the fourth splicing plate 14. The first splicing plate 11, the second splicing plate 12, the third splicing plate 13, and the fourth splicing plate 14 all have the same outer contour and are flush with each other. The second splicing plate 12 and the third splicing plate 13 are alternately arranged between the first splicing plate 11 and the fourth splicing plate 14. Two splicing panels 12, two third splicing panels 13; and the first splicing panels 11 and the fourth splicing panels 14 on both sides are adjacent to the first splicing panel 11. The first through holes 121 of the three second splicing panels 12 are all arranged facing each other, and the first through holes 121 and the second through holes 131 are arranged facing each other. The second through holes 131 of the adjacent third splicing panels 13 are staggered. The purpose is to allow the three first through holes 121 of the three second splicing panels 12 and the two second through holes 131 of the two third splicing panels 13 to communicate with each other to form an S-shaped channel.

[0034] Reference Figure 1 and Figure 2 As shown, in order to improve the efficiency and uniformity of spraying, both the first through hole 121 and the second through hole 131 are rectangular and extend horizontally, so that the hollow cavity 16 extends horizontally. Multiple outlets 141 are evenly distributed along the length of the first through hole 121, and the diameter of the outlet 141 is smaller than the diameter of the inlet 111. When the atomized oily sealing agent enters the hollow cavity 16, the oily sealing agent diffuses to both sides of the hollow cavity 16 and is finally evenly sprayed out from the multiple outlets 141.

[0035] Reference Figure 1As shown, the inlet 111 of the first splicing plate 11 and the outlet 141 of the fourth splicing plate 14 are both positioned directly opposite the first through hole 121. The purpose of this is to ensure that the atomized oily sealant can enter the first through hole 121 of the first second splicing plate 12 from the inlet 111 and be sprayed out of the outlet 141 from the first through hole 121 of the last second splicing plate 12.

[0036] Reference Figure 1 As shown, a blocking part 132 is further provided in the middle of the second through hole 131. The blocking part 132 is positioned directly opposite the feed inlet 111. The blocking part 132 guides the atomized oily sealant entering the first through hole from the feed inlet 111, causing the atomized oily sealant to diffuse to both sides of the second through hole 131, preventing the atomized oily sealant from being too concentrated in the hollow cavity.

[0037] Example 2

[0038] Reference Figure 5 As shown, to solve the above problems, a spray oil sealing fixture is also provided, including the nozzle and a closed first housing 2. The nozzle is disposed in the first housing 2. The nozzle is used to spray atomized oily sealing agent to seal the material belt 6 located in the first housing 2. The first housing 2 can prevent the atomized oily sealing agent from spreading to other work stations and causing pollution.

[0039] Reference Figure 6 As shown, in order to collect excess oily sealant, the bottom of the first box 2 is configured as a funnel structure 23, and the bottom of the funnel structure 23 is provided with a discharge port 231. After the oily sealant adheres to the surface of the funnel structure 23, it gathers into liquid oily sealant and is discharged to the outside of the first box 2 through the discharge port 231.

[0040] Reference Figure 5 As shown, in order to quickly dry and cure the material strip 6 after it is covered with a layer of oily sealant, a closed second box 3 is also included. The second box 3 is located on one side of the first box 2. The second box 3 is equipped with a drying component. The material strip 6 covered with oily sealant is conveyed to the second box 3. The drying component located below the material strip 6 heats it to 100°C for drying. In order to heat the material strip 6 evenly, a perforated plate 4 is provided between the drying component and the material strip 6. Multiple round holes arrayed on the perforated plate 4 evenly distribute the hot air.

[0041] Reference Figure 4 and Figure 5As shown, since the material strip 6 (continuous PIN terminals) is strip-shaped, in order to realize the automated conveying of the material strip 6 and improve the oil sealing efficiency, the first feeding port 3 is arranged opposite to the two side walls of the first box 2, and the second feeding port 31 is arranged opposite to the two side walls of the second box 3. The first feeding port 3 and the second feeding port 31 are arranged opposite to each other. The material strip 6 passes through the first feeding port 3 and the second feeding port 31 through the first box 2 and the second box 3. During oil sealing, one end of the material strip 6 moves slowly under the traction of the traction machine, so as to realize the continuous and uninterrupted operation of oil sealing and drying in sequence.

[0042] Reference Figure 4 As shown, in order to prevent the strip material 6 from swaying during the conveying process and causing unevenness of the protective film of the oily sealing agent, a roller assembly is also included at the first feed port 3 and the second feed port 31. The roller assembly includes a mounting base 8 connected to the side wall of the second housing 3, two vertical rollers 81 facing each other and vertically arranged, and a horizontal roller 82 arranged horizontally. The vertical rollers 81 and the horizontal rollers 82 are rotatably connected to the mounting base 8. The two vertical rollers 81 are positioned facing the first feed port 3, and the horizontal rollers 82 are positioned facing the gap between the two vertical rollers 81. The strip material 6 passes through the gap between the two vertical rollers 81 before entering the second housing 3 and after leaving the second housing 3, and the bottom of the strip material 6 is supported by the horizontal rollers 82.

[0043] Reference Figure 5 As shown, in order to recover and process excess atomized oily sealing agent and save raw materials, a recovery component 7 is also included outside the first housing 2. The recovery component 7 includes an air pipe, a filter screen located inside the air pipe, an oil storage tank located below the filter screen, and an air pump. One end of the air pipe is connected to the interior of the first housing 2, and the other end is connected to the air pump. The air pump extracts the air and excess atomized oily sealing agent from the first housing 2. The filter screen filters the atomized oily sealing agent and air. The oily sealing agent adheres to the filter screen and finally drips into the oil storage tank to achieve recovery.

[0044] The working principle of the nozzle and spray oil seal fixture described in this utility model is as follows:

[0045] One end of the metering pump connecting pipe is inserted into the oil storage tank, and the other end is connected to the liquid port of the atomizer 5. The gas port of the atomizer 5 is connected to the air pipe extending from the air-oil-water separator. After ensuring that all pipes are properly connected, the air pressure in the air pipe is set to 0.4 atmospheres. The traction machine starts to convey the material belt 6 through the first box 2 and the second box 3 in sequence. At the same time, the atomizer 5 sprays atomized oily sealing agent into the nozzle body 1 through the feed inlet 111. When the atomized oily sealing agent passes through the S-shaped channel, the atomized oil... The dotted liquid oil in the sealant is blocked by the baffle 15 and the inner wall of the hollow cavity 16 and remains at the bottom of the S-shaped channel. After the atomized oil sealant is sprayed out from the outlet 141, it continuously and evenly diffuses in the first box 2 and finally adheres to the surface of the material belt 6 to form a uniform and dense protective film of atomized oil sealant. Then, after the material belt 6 is conveyed to the second box 3, the protective film of oil sealant covering the surface of the material belt 6 is dried and solidified by the drying component, realizing continuous and uninterrupted operation of oil sealing and drying.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
