Abstract
Description
Technical Field
[0001] The utility model relates to the field of PCB board plating, in particular to a sampling box. Background Art
[0002] During the electroplating process of PCB boards, the PCB boards need to be immersed in electrolyte and a layer of metal ions is plated on the PCB boards by applying current.
[0003] Before electroplating, the concentration of the electrolyte needs to be measured. In existing electroplating equipment, the electrolyte is stored in a chemical liquid pool with an open structure. The conventional sampling method is to manually twist a measuring cup and scoop out a certain amount of the chemical liquid pool. This sampling method is unsafe. The electrolyte is corrosive and splashing onto the skin can cause skin ulcers and other conditions.
[0004] Another sampling method is to use a pipe with a valve body and place the sampling cup at the bottom of the pipe. The pipe is in a vertical position and the discharge port is set at the bottom. By opening the valve body, the pipe discharges the electrolyte. This treatment method can avoid close contact with the human body, but the electrolyte will splash around, causing new cleaning problems for the ground and causing corrosion to the ground. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a sampling box, which can replace the method of measuring cup and spoon for electrolyte, does not require close assistance of human body for sampling, and can also prevent corrosion of the bottom surface.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sampling box, comprising a box body with an internal hollow cavity structure, a support plate for supporting the sampling piece is also provided in the cavity structure, a plurality of drainage holes are provided on the support plate, and a liquid outlet hole is provided at the bottom of the cavity structure, and a liquid inlet pipe connected to the chemical liquid pool and a nozzle for spraying clean water are provided above the inside of the box body.
[0007] Furthermore, the box body is a rectangle formed by sequentially connecting four side panels, wherein at least one side panel is a movable first side panel, and the first side panel is attached to the inner side surface of the adjacent side panel and moves up and down.
[0008] Furthermore, a handle is connected to the top of the first side panel.
[0009] Furthermore, a surface of the first side panel has a viewing window.
[0010] Furthermore, the support plate and the cavity structure are detachably connected.
[0011] Furthermore, the detachable connection is that the inner side plate of the box body is provided with a support bar, and the support plate is directly mounted on the support bar.
[0012] Furthermore, the bottom of the cavity structure is a three-section structure, the middle area is lower than the two sides, the areas on both sides are inclined toward the middle area, and the liquid outlet is located in the middle area.
[0013] Beneficial effects of the utility model:
[0014] 1. The entire sampling process involves operations that involve close contact with the human body. These operations revolve around the two parts of inserting the sampling piece and opening the valve from the outside and removing the sampling piece. The two parts are respectively in the stages before and after sampling. There is no close participation in the sampling process. For the traditional sampling method, directly twisting the measuring cup to take samples will easily cause the skin to contact the electrolyte and cause skin ulcers. This problem can be completely solved. In other words, the safety of sampling has been significantly improved.
[0015] 2. After the sampling is completed, the nozzle will continue to spray clean water to flush the electrolyte remaining in the box during sampling, and discharge it through the drainage hole and the outlet hole in sequence. It can be seen that the problem of inconvenience in cleaning the ground caused by sputtering in the prior art has been solved. Therefore, the utility model solves the safety problem and the problem of ground corrosion at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] References in the specification to "one embodiment," "an embodiment," or "some embodiments" mean that a particular feature, structure, or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, phrases in the specification referring to "in one embodiment," "in an embodiment," or "in some embodiments" are not necessarily referring to the same embodiment or embodiments. The particular features, structures, or elements may be further combined in any suitable manner in any embodiment.
[0020] like Figure 1-3As shown, a sampling box includes a box body, which has at least one side that presents an internal hollow cavity structure when opened, and a support plate 1 for supporting the sampling piece is further provided in the cavity structure, and a plurality of drainage holes 1a are provided on the support plate 1, and a liquid outlet hole 2 is provided at the bottom of the cavity structure. Above the inside of the box body, there are provided a liquid inlet pipe 3 connected to the chemical liquid pool and a nozzle 4 for spraying clean water. The end of the liquid inlet pipe 3 inside the box body is facing the support plate 1. After the position of the sampling piece corresponds to the end of the liquid inlet pipe 3, it is placed on the support plate 1, and then the opened side of the box body is closed, and the corresponding valve is opened, and the electrolyte is poured into the sampling piece from the liquid inlet pipe 3; after obtaining a certain amount of electrolyte, the valve is closed, the side is opened, and the sampling piece is taken away.
[0021] The entire sampling process involves operations that involve close contact with the human body, centered around inserting the sampling piece and removing the sampling piece after opening the valve from the outside. The two parts are respectively in the pre-sampling and post-sampling stages, and there is no close involvement in the sampling process. For the traditional sampling method, directly twisting the measuring cup to take samples will easily cause the skin to contact the electrolyte and cause skin ulcers. This problem can be completely solved. In other words, the safety of sampling has been significantly improved.
[0022] After the sampling is completed, the nozzle 4 will continue to spray clean water to flush the electrolyte remaining in the box body. The electrolyte is discharged through the drainage hole 1a and the liquid outlet hole 2 in sequence. It can be seen that the utility model solves the safety problem and the ground corrosion problem at the same time.
[0023] The box body is a rectangle formed by sequentially connecting four side panels. In this embodiment, the movable first side panel 5 is attached to the inner side surface of the adjacent side panel and moves up and down.
[0024] The nozzle 4 is connected to the clean water tank and is also controlled by a valve.
[0025] The valves mentioned above for controlling the shutoff or flow of liquid in the nozzle 4 and the liquid inlet pipe 3 are prior art, and therefore, their structures are not described in detail here.
[0026] In order to facilitate opening of the first side panel 5 , a handle 5 a is connected to the top of the first side panel 5 .
[0027] In some embodiments, the surface of the first side plate 5 has a visual window 5b, which is made of a transparent material for observing the extent to which the sampling member collects the electrolyte; the transparent material is, for example, transparent PVC.
[0028] The support plate 1 and the cavity structure are connected in a detachable manner. After the sampling is completed, the support plate 1 can be taken out separately and cleaned.
[0029] The inner plate is provided with a support bar 5c, and the support plate 1 is directly mounted on the support bar 5c. This support method has the characteristics of easy assembly and disassembly.
[0030] It should be noted that in order to prevent the accumulation of clean water or electrolyte at the bottom of the cavity structure, the bottom of the cavity structure is a three-section structural bottom plate 6. The middle area is located lower than the two sides, and the areas on both sides are inclined toward the middle area. The liquid outlet 2 is located in the middle area, and the electrolyte or clean water flows toward the liquid outlet 2 along the inclined direction.
[0031] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not 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 technicians in this field should fall within the scope of protection determined by the claims of the present invention.
