Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 One embodiment provided by this utility model:

[0031] A copper sheet salt spray test apparatus, comprising:

[0032] Test chamber 1 has a sealing cover 2 installed on its top. The bottom of test chamber 1 is connected and fixed to the top of treatment chamber 3. A transfer tube 4 is installed through one side of the connection between the bottom of test chamber 1 and the top of treatment chamber 3. The bottom surfaces of test chamber 1 and treatment chamber 3 are both set as slopes, and the inclination directions of the bottom slopes of test chamber 1 and treatment chamber 3 are opposite. The transfer tube 4 is installed at the center of the lowest end of the bottom slope of test chamber 1. The above structural design allows the dripping salt spray test solution to quickly enter the treatment chamber 3 from the transfer tube 4 along the bottom slope of test chamber 1, which is convenient for the neutralization mechanism in the treatment chamber 3 to process. A side shaft 5 is installed in the middle of the side wall of test chamber 1. A crank 6 is fixed at the end of the side shaft 5 located on the outside of test chamber 1.

[0033] Side shaft 5, located at the end inside the test chamber 1, is connected and fixed to the outer side of the movable frame 7. The center of side shaft 5 and the center of movable frame 7 are on the same horizontal straight line. The frontal length of movable frame 7 is greater than 3 / 4 of the frontal length of test chamber 1. The above structural design allows movable frame 7 to rotate stably around side shaft 5, and the size is sufficient to install multiple mobile phone copper plates inside. The center of movable frame 7 and the center of test chamber 1 are on the same vertical plane. The sideal length of movable frame 7 is less than the sideal width of test chamber 1. The above structural design ensures that movable frame 7 and its mounting mechanism will not collide with the inner wall of test chamber 1 when rotating. The top and bottom of movable frame 7 are provided with track windows 8. Positioning bolts 9 are installed through the track windows 8. Positioning nuts 10 are installed on the positioning bolts 9. Positioning clips 11 are fixedly installed at the ends of positioning bolts 9.

[0034] Test chamber 1, with an inlet pipe 12 fixed at the bottom of the side wall near the treatment chamber 3, and a first nozzle 13 installed at the top of the inlet pipe 12. Neutralizing liquid pipe 14 is fixed at the top of the inner wall of the treatment chamber 3, and a second nozzle 15 is installed at the bottom of the neutralizing liquid pipe 14. Waste discharge pipe 16 is installed at the bottom of one side of the treatment chamber 3.

[0035] In one embodiment, the positioning bolt 9 is slidably connected to the track window 8, and the length of the track window 8 is greater than 3 / 4 of the frontal length of the movable frame 7. The above structural design allows the positioning bolt 9 to slide smoothly and over a wide range of lateral and longitudinal adjustments along the track window 8.

[0036] In one of the preferred embodiments, the track windows 8 are symmetrically distributed about the center of the movable frame 7. Positioning nuts 10 are symmetrically installed on the positioning bolts 9 on the upper and lower sides of the track windows 8. The above structural design enables the relative position of the positioning bolts 9 and the track windows 8 to be adjusted conveniently, and facilitates the symmetrical installation of the positioning cards 11.

[0037] In one of the embodiments, the side view cross-sectional shape of the positioning card 11 is "U"-shaped, and the positioning cards 11 are symmetrically distributed about the center of the movable frame 7. The above structural design can stably squeeze and position the two ends of the mobile phone copper sheets of different sizes.

[0038] In one of the preferred embodiments, the liquid inlet pipes 12 and the neutralizing liquid pipes 14 are both horizontally and equally spaced. First nozzles 13 are equally spaced and installed on the top of the liquid inlet pipes 12, and second nozzles 15 are equally spaced and installed on the bottom of the neutralizing liquid pipes 14. The above structural design enables the salt spray test solution and the neutralizing liquid to be sprayed evenly, ensuring the test effect and the harmless treatment effect.

[0039] The working principle of the present utility model is as follows: When in use, open the sealing cover 2 and turn the Figure 2 positioning nuts 10 symmetrically distributed on the positioning bolts 9 away from the inner and outer surfaces of the movable frame 7. According to the size of the mobile phone copper sheet to be tested, push the positioning bolts 9 to slide horizontally and vertically along the track windows 8, adjust the spacing between adjacent positioning cards 11 and the spacing between the symmetric positioning cards 11, insert the mobile phone copper sheet into the inner side of the symmetrically distributed positioning cards 11, and the inner walls of the positioning cards 11 squeeze the mobile phone copper sheet from both ends to fix it. Rotate the symmetrically distributed positioning nuts 10 to squeeze and fix them against the inner and outer surfaces of the movable frame 7, and fix the mobile phone copper sheets of different sizes;

[0040] Then close the sealing cover 2, and evenly shake the side shaft 5 through the crank 6. The side shaft 5 drives the movable frame 7 and the mobile phone copper sheet to rotate stably. The salt spray test solution is sprayed upward from the first nozzles 13 through the liquid pump connected to the liquid inlet pipe 12, and the salt spray contacts the mobile phone copper sheet evenly. After completing the test according to the test requirements, open the sealing cover 2, loosen the positioning nuts 10, and remove the mobile phone copper sheet;

[0041] During the test, the dripping salt spray solution flows along the inner bottom surface of the inclined test chamber 1 to the transfer pipe 4 and falls into the treatment chamber 3 through the transfer pipe 4. When the salt spray solution flows along the inclined surface at the bottom of the inner side of the treatment chamber 3, the neutralizing liquid is sprayed downward through the second nozzles 15 by the liquid pump connected to the neutralizing liquid pipe 14, and is fully mixed with the flowing salt spray solution below to perform harmless treatment on the salt spray solution. Open the waste discharge pipe 16 regularly to discharge the neutralized waste liquid.

[0042] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
