Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Figure 1 and Figure 2 As shown, the preparation method of the pure copper tube holder for chip placement includes the following steps: Step 1: Incoming material inspection: Check the surface of the raw materials for scratches, cracks, rust and stains by visual inspection or using a magnifying glass, and remove the raw materials with cracks and rust, as well as serious scratches and stains.

[0024] Example 2: Figure 2 and Figure 3 As shown, when other parts are the same as those in the embodiment, the difference between this embodiment and the embodiment is that: The cleaning and drying device includes a mounting frame 100 , a cleaning mechanism 200 and a drying mechanism 300 .

[0025] The cleaning mechanism 200 includes a fixed cylinder 201 , a fixed cover 203 , a net cylinder 204 , a movable seat 205 , a mounting cylinder 206 and a driving assembly 210 .

[0026] The fixed cylinder 201 is installed on the top surface of the mounting frame 100, and the fixed cylinder 201 is used to contain pure water; the fixed cover 203 is installed on the inner bottom surface of the fixed cylinder 201; the net cylinder 204 is slidably connected to the inner wall of the fixed cylinder 201, and the net cylinder 204 is used to place the cleaned objects; the movable seat 205 is installed through the bottom surface of the net cylinder 204; the mounting cylinder 206 is fixedly connected to the inner bottom surface of the net cylinder 204, and the mounting cylinder 206 cover is arranged on the movable seat 205; the driving assembly 210 is used to drive the net cylinder 204 to move back and forth up and down, so that the net cylinder 204 is intermittently in contact with the pure water in the fixed cylinder 201.

[0027] The drying mechanism 300 is installed on the mounting frame 100 , and is used to dry the objects to be cleaned located on the net cylinder 204 .

[0028] Specifically, pure water is added into the fixed cylinder 201, and the items to be cleaned are placed in the net cylinder 204. Then, the driving component 210 drives the net cylinder 204 to move up and down reciprocatingly. When the net cylinder 204 moves downward, the net cylinder 204 and the cleaned items in the net cylinder 204 will sink into the pure water. When the net cylinder 204 moves upward, the net cylinder 204 and the cleaned items in the net cylinder 204 will be separated from the pure water. The reciprocating up and down movement of the net cylinder 204 allows the cleaned items to be cleaned with pure water.

[0029] After cleaning is completed, the net cylinder 204 is separated from the pure water by the driving assembly 210 , and then air is blown toward the net cylinder 204 by the drying mechanism 300 , so that the cleaned objects in the net cylinder 204 are dried quickly.

[0030] like Figure 3 and Figure 4 As shown, the driving assembly 210 includes a reciprocating screw 211 , an impeller 212 , a cross pipe 213 , an air nozzle 214 , a high-pressure air pump 215 and an air delivery hose 216 .

[0031] The reciprocating screw 211 penetrates the top surface of the fixed cover 203 and is rotatably connected to the fixed cover 203. The reciprocating screw 211 penetrates the movable seat 205, and the movable seat 205 can reciprocate up and down along the reciprocating screw 211. The impeller 212 is located in the fixed cover 203, and the impeller 212 is installed on the reciprocating screw 211; the transverse pipe 213 penetrates the side of the fixed cover 203 and is fixedly connected to the fixed cover 203; the air nozzle 214 is located in the fixed cover 203, and the air nozzle 214 is fixedly connected to the transverse pipe 213, and the air nozzle 214 faces the impeller 212; the high-pressure air pump 215 is installed on the mounting frame 100; one end of the air delivery hose 216 is fixedly connected to the air outlet end of the high-pressure air pump 215, and the other end of the air delivery hose 216 is detachably connected to the transverse pipe 213.

[0032] Specifically, when the high-pressure air pump 215 is running, the high-pressure gas will be delivered to the horizontal pipe 213 through the air delivery hose 216, and the high-pressure gas will be blown out through the air nozzle 214. The gas blown out of the air nozzle 214 will drive the impeller 212 to rotate, thereby driving the reciprocating screw 211 to rotate, and then causing the movable seat 205 to move back and forth up and down along the reciprocating screw 211, thereby driving the net cylinder 204 to move back and forth up and down, and then causing the net cylinder 204 to intermittently contact the pure water in the fixed cylinder 201.

[0033] like Figure 3-Figure 5 As shown, the cleaning mechanism 200 further includes a water stirring assembly 220 , and the water stirring assembly 220 includes a hollow ring 221 , a plurality of exhaust pipes 222 and an air guide pipe 223 .

[0034] The hollow ring 221 is installed on the inner bottom surface of the fixed cylinder 201; multiple exhaust pipes 222 are installed on the top surface of the hollow ring 221, and a one-way valve is installed in the exhaust pipe 222, so that pure water cannot enter the hollow ring 221 through the exhaust pipe 222. One end of the air guide pipe 223 is fixedly connected to the hollow ring 221, and the other end of the air guide pipe 223 is fixedly connected to the fixed cover 203.

[0035] Specifically, the air in the fixed cover 203 will enter the hollow ring 221 through the exhaust pipe 222, and the air in the hollow ring 221 will be discharged through multiple exhaust pipes 222. When the air is discharged through the exhaust pipe 222, bubbles will form and rise. When the bubbles rise, they disturb the pure water in the fixed cylinder 201, which helps to loosen and remove dirt and impurities on the surface of the object to be cleaned, thereby improving the cleaning effect and improving the cleaning efficiency.

[0036] like Figure 4 and Figure 5 As shown, the cleaning mechanism 200 further includes a guide groove 202 and a guide block 207. The guide groove 202 is formed on the inner wall of the fixed cylinder 201; the guide block 207 is installed on the side of the net cylinder 204, and the guide block 207 is slidably connected to the guide groove 202.

[0037] The guide groove 202 and the guide block 207 are provided to improve the stability of the net cylinder 204 when it moves.

[0038] like Figure 6-Figure 8 As shown, the drying mechanism 300 includes a hollow plate 301, a plurality of air outlet pipes 302, a fixed pipe 303, a fixed frame 304 and a driven gear 305. The hollow plate 301 is located directly above the net tube 204; the plurality of air outlet pipes 302 are all installed on the bottom surface of the hollow plate 301; the fixed pipe 303 is fixedly connected to the hollow plate 301; the fixed frame 304 is fixedly installed on the mounting frame 100, and the fixed frame 304 is rotatably connected to the fixed pipe 303; and the driven gear 305 is fixedly sleeved on the fixed pipe 303.

[0039] Specifically, when the cleaned objects in the mesh tube 204 need to be dried, the mesh tube 204 is separated from the pure water, and air is then transported into the fixed tube 303. The air enters the hollow plate 301, and the air in the hollow plate 301 is discharged through multiple air outlet pipes 302. The air discharged from the air outlet pipes 302 is blown toward the cleaned objects in the mesh tube 204, thereby accelerating the drying efficiency of the cleaned objects.

[0040] When the cleaned objects in the net cylinder 204 are dried, the hollow plate 301 and the plurality of air outlet pipes 302 can be driven to rotate by rotating the fixed pipe 303, thereby increasing the coverage of the air discharged by the air outlet pipes 302, thereby drying the cleaned objects in the net cylinder 204 more comprehensively.

[0041] like Figure 7As shown, the drying mechanism 300 further includes an air guide assembly 310, which includes a support frame 311, a first curved pipe 312, a connecting tube 313, and a second curved pipe 314. The support frame 311 is fixedly connected to the mounting frame 100; the first curved pipe 312 is installed on the support frame 311, and one end of the first curved pipe 312 matches the gas hose 216; the connecting tube 313 is fixedly connected to one end of the first curved pipe 312; one end of the second curved pipe 314 is fixedly connected to the connecting tube 313, and the other end of the second curved pipe 314 is rotatably connected to the fixed pipe 303.

[0042] Specifically, when it is necessary to dry the cleaned object in the mesh tube 204, one end of the air hose 216 is separated from the horizontal tube 213, and the air hose 216 is connected to the lower end of the first curved pipe 312 and fastened with a throat clamp, and then the high-pressure air pump 215 is started. The high-pressure air pump 215 will transport air into the air hose 216, and the air will enter the first curved pipe 312, the connecting tube 313 and the second curved pipe 314 in turn. The air in the second curved pipe 314 will enter the hollow plate 301 through the fixed pipe 303.

[0043] like Figure 8 As shown, the air guide assembly 310 also includes a vertical plate 315 , a rotating shaft 3151 , a plurality of fan blades 3152 , a first bevel gear 3153 , a vertical rod 316 , a second bevel gear 317 and a driving gear 318 .

[0044] The vertical plate 315 is installed in the connecting tube 313; the rotating shaft 3151 is rotatably installed on the vertical plate 315; the plurality of fan blades 3152 are all installed on the rotating shaft 3151; the first bevel gear 3153 is fixedly sleeved on the rotating shaft 3151; the vertical rod 316 passes through one side of the connecting tube 313 and is rotatably connected to the connecting tube 313; the second bevel gear 317 is installed at the upper end of the vertical rod 316, and the second bevel gear 317 is meshedly connected with the first bevel gear 3153; the driving gear 318 is installed at the lower end of the vertical rod 316, and the driving gear 318 is meshedly connected with the driven gear 305.

[0045] Specifically, when the air in the first curved pipe 312 enters the connecting tube 313, it will drive the fan blades 3152 to rotate, and then drive the rotating shaft 3151 to rotate, and then drive the first bevel gear 3153 to rotate. The rotating first bevel gear 3153 will engage and drive the second bevel gear 317 to rotate, and then drive the vertical rod 316 to rotate, and then drive the driving gear 318 to rotate, and then engage and drive the driven gear 305 to rotate, and then drive the fixed pipe 303, the hollow plate 301 and the air outlet pipe 302 to rotate.

[0046] Working principle: When in use, pure water is added into the fixed cylinder 201 , and then the items to be cleaned are placed in the net cylinder 204 .

[0047] Then, by starting the high-pressure air pump 215, the high-pressure air pump 215 transmits high-pressure gas to the cross tube 213 through the air hose 216, and the high-pressure gas in the cross tube 213 is blown out through the air nozzle 214. The gas blown out by the air nozzle 214 will blow the impeller 212 to rotate, thereby driving the reciprocating screw 211 to rotate, and then causing the movable seat 205 to move back and forth up and down along the reciprocating screw 211, thereby driving the net cylinder 204 to move back and forth up and down, and then causing the net cylinder 204 to intermittently contact with the pure water in the fixed cylinder 201, so as to use the pure water to clean the object to be cleaned.

[0048] The air in the fixed cover 203 will enter the hollow ring 221 through the exhaust pipe 222, and the air in the hollow ring 221 will be discharged through multiple exhaust pipes 222. When the air is discharged through the exhaust pipes 222, bubbles will form and rise. When the bubbles rise, they will disturb the pure water in the fixed cylinder 201, which will help loosen and remove dirt and impurities on the surface of the object to be cleaned, thereby improving the cleaning effect and improving the cleaning efficiency.

[0049] After cleaning is completed, the mesh cylinder 204 is transported upward by the driving assembly 210 to separate the mesh cylinder 204 from the pure water.

[0050] Then, one end of the air delivery hose 216 is separated from the cross pipe 213, and the air delivery hose 216 is connected to the lower end of the first curved pipe 312 and fastened with a throat clamp. Then, by starting the high-pressure air pump 215, the high-pressure air pump 215 will deliver air to the air delivery hose 216. The air enters the first curved pipe 312, the connecting tube 313 and the second curved pipe 314 in turn. The air in the second curved pipe 314 will enter the hollow plate 301 through the fixed pipe 303. The air in the hollow plate 301 will be discharged through multiple air outlet pipes 302. The air discharged from the air outlet pipes 302 will be blown toward the cleaned objects in the mesh tube 204, thereby accelerating the drying efficiency of the cleaned objects.

[0051] When air passes through the connecting tube 313, the flowing air will drive the fan blades 3152 to rotate, and then drive the rotating shaft 3151 to rotate, and then drive the first bevel gear 3153 to rotate. The rotating first bevel gear 3153 will mesh and drive the second bevel gear 317 to rotate, and then drive the vertical rod 316 to rotate, and then drive the driving gear 318 to rotate, and then mesh and drive the driven gear 305 to rotate, and then drive the fixed tube 303, the hollow plate 301 and the air outlet pipe 302 to rotate, thereby increasing the coverage of the air discharged by the air outlet pipe 302, so as to more comprehensively dry the cleaned objects in the net tube 204.

[0052] Example 3: Figure 9-11As shown, when other parts are the same as those in Example 2, the difference between this embodiment and Example 2 is that the cleaning and drying equipment also includes a bracket 101, a support block 102, two moving wheels 103, two mounting rods 104 and a push handle 105.

[0053] The bracket 101 is installed on the top surface of the mounting frame 100; the support block 102 is installed on the bottom surface of the mounting frame 100; the two moving wheels 103 are both installed on the bottom surface of the mounting frame 100; the two mounting rods 104 are respectively installed on the front and back of the support block 102; and the push handle 105 is installed on the mounting frame 100.

[0054] like Fig. 9 As shown, the driving assembly 210 further includes a first filter cover 217, a second filter cover 218 and two rotating drums 219. The first filter cover 217 is placed on the bracket 101, and the first filter cover 217 covers the air inlet end of the high-pressure air pump 215; the second filter cover 218 is placed on the bracket 101, and the second filter cover 218 contacts the first filter cover 217; the first filter cover 217 and the second filter cover 218 are both cylindrical, and the plane parts of the first filter cover 217 and the second filter cover 218 are both filter plates, and the filter hole diameter of the second filter cover 218 is larger than the filter hole diameter of the first filter cover 217.
