Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a dry ice cleaning machine. Background Art

[0002] In the electronics processing industry, circuit board cleaning is a vital link. In order to remove pollutants generated during the electronics manufacturing process, such as flux, solder paste and adhesives, the circuit boards are usually spray-cleaned with cleaning fluid. However, there are some obvious problems with this cleaning method. First, the chemical components in the cleaning fluid may damage the circuit board, thereby affecting its stability and increasing the failure rate. Secondly, the waste liquid treatment of the cleaning fluid will not only pollute the environment, but the toxins and volatile harmful gases it produces may also pose a threat to the health of the cleaning personnel.

[0003] In order to solve these problems, dry ice washer was introduced into the circuit board cleaning process. Dry ice, that is, solid carbon dioxide, can absorb a lot of heat during the sublimation process due to its physical properties, thereby achieving the effect of cooling and cleaning. Dry ice washer uses this property of dry ice to clean circuit boards. It not only has a good cleaning effect, but also does not cause chemical damage to the circuit board. The treatment of exhaust gas is also relatively simple, and will not cause too much pressure on the environment.

[0004] However, the use of dry ice plate washing machine is inseparable from dry ice cleaning machine. Dry ice cleaning machine is responsible for crushing large pieces of dry ice into fine particles suitable for cleaning and then supplying them to the outside through pipes. However, existing dry ice cleaning machines often get blocked during the dry ice crushing and feeding process. Once blocked, it will not only affect the supply of dry ice, and then affect the cleaning efficiency of the dry ice plate washing machine, but may also cause damage to the dry ice cleaning machine itself.

[0005] Therefore, there is an urgent need for a dry ice cleaning machine that can effectively prevent material discharge blockage. Utility Model Content

[0036] See attached Figure 1 To Attachment Figure 6 , the figure shows a specific embodiment of a dry ice cleaning machine provided by the utility model.

[0037] See attached Figure 1 and attached Figure 2 , dry ice cleaning machine includes:

[0038] The machine body 1 is provided with a feeding port 110;

[0039] A dry ice bin 2 is disposed in the body 1, and the dry ice bin 2 is connected to the loading port 110;

[0041] An ice pushing mechanism 4 movably mounted in the dry ice bin 2, the ice pushing mechanism 4 is used to push the dry ice in the dry ice bin 2 toward the blade 3;

[0042] A feeding mechanism 5 is arranged near the cutter disc 3 , and the feeding mechanism 5 is used to receive high-pressure air to spray out the dry ice crushed by the cutter disc 3 .

[0043] See attached Figure 2 and attached Figure 3 In the above embodiment, dry ice is placed in the dry ice bin 2 through the loading port 110. When the operation is started, the ice pushing mechanism 4 in the dry ice bin 2 pushes the dry ice to move toward the cutter disc 3. The cutter disc 3 is provided with a plurality of blades. When the cutter disc 3 rotates, the dry ice is crushed into dry ice particles. In some embodiments, the ice pushing mechanism 4 can be arranged at the top and the cutter disc 3 is arranged at the bottom, so as to push the dry ice from top to bottom. In this embodiment, the ice pushing mechanism 4 and the cutter disc 3 are arranged at the left and right ends of the dry ice bin 2, and the ice pushing mechanism 4 pushes the dry ice in the dry ice bin 2 in a lateral movement. The crushed dry ice particles fall into the unloading mechanism 5 and are ejected by high-pressure air, thereby preventing the dry ice particles from freezing and clogging in the unloading mechanism 5.

[0044] See attached Figure 3 and attached Figure 5 In the above embodiment, the unloading mechanism 5 includes a guide groove 510, and a unloading shaft 520 rotatably arranged at the lower end of the guide groove 510. The unloading shaft 520 is provided with a plurality of unloading grooves 521 along the circumference. When high-pressure air is blown into the unloading groove 521, the dry ice in the unloading groove 521 is taken out. In the embodiment, the guide groove 510 guides the dry ice particles crushed by the blade 3 and collects them into the unloading groove 521 of the unloading shaft 520. In the embodiment, the unloading shaft 520 is provided with two rows of unloading grooves 521 in the circumference, and each row has 6 unloading grooves 521 evenly arranged, and the two rows of unloading grooves 521 are staggered with each other. The dry ice particles fall from the guide groove 510 from top to bottom into the discharge groove 521. When the discharge shaft 520 rotates, the dry ice particles are driven downward, and then high-pressure air is blown into the discharge groove 521 to spray the dry ice particles out. At the same time, other discharge grooves 521 also rotate to receive the dry ice particles falling from the guide groove 510 from top to bottom, so as to avoid a large amount of dry ice particles accumulating and causing freezing.

In the embodiment, the unloading funnel 530 is used to limit the flow path of the high-pressure air so that the high-pressure air can only enter one unloading groove 521. Among them, the air input port 532 and the air output port 533 correspond to a discharge trough 521 at the same time. When the high-pressure air is sprayed into the discharge trough 521 from the air input port 532, the dry ice particles are sprayed out from the air output port 533. By limiting the effective range of the high-pressure air, the spraying force on a single discharge trough 521 is increased, so that the high-pressure air can bring out the dry ice particles in the discharge trough 521 completely, further avoiding ice blockage.
