[0042] The first holding device 5 is detachably mounted on the drive shaft 43;

[0043] The conveying device 8 includes a feeding device 81 and a discharging device 82, which are respectively arranged on both sides of the cleaning device 1.

[0044] During operation, after the diodes to be cleaned are placed in the first holding device 5, the first holding device 5 containing the diodes is transported to the support frame 21 by the feeding device 81. The drive device 22 is started, and the output end drives the slider 23 to move. The slider 23 drives the lifting device 3 to move. The lifting device 3 drives the transmission device 4 to move. When the slider 23 moves above the first holding device 5, the lifting device 3 is started, and the output end drives the transmission device 4 to descend. After the first holding device 5 is assembled with the transmission shaft 43, the lifting device 3 is started, and the output end drives the protective shell 41 to rise. The protective shell 41 drives the first holding device 5 to rise through the transmission shaft 43. At the same time, the drive device 22 is started, and the output end drives the slider 23 and the lifting device 3 to move. The lifting device 3 drives the protective shell 41 to move. The protective shell 41 drives the transmission shaft 43 and the first holding device 5 to move.

[0045] When the first holding device 5 moves above the cleaning tank 11, the drive device 22 stops working and the lifting device 3 is activated. The output end drives the protective shell 41 and the drive shaft 43 to descend. The drive shaft 43 drives the first holding device 5 to descend into the cleaning tank 11. The cleaning tank 11 contains chemical cleaning solution to soak the diode and remove surface contaminants. During cleaning, the second motor 42 is activated, and the output end drives the drive shaft 43 to rotate slowly. The drive shaft 43 drives the first holding device 5 and the internal diode to rotate. At the same time, the lifting device 3 is activated, and the output end drives the first holding device 5 and the internal diode to move up and down continuously through the protective shell 41 and the drive shaft 43. During cleaning, the lifting device 3 and the second motor 42 drive the diode to rotate up and down, so that the cleaning solution can fully contact the surface of the diode, while preventing contaminants from settling on the diode surface, thus achieving a better cleaning effect.

[0046] After cleaning, turn off the second motor 42, start the lifting device 3 to lift the first holding device 5 from the cleaning tank 11, start the drive device 22 to move the first holding device 5 above the rinsing tank 12, start the lifting device 3 to put the first holding device 5 into the rinsing tank 12, the lifting device 3 drives the first holding device 5 to move up and down, and at the same time start the second motor 42 to drive the first holding device 5 to rotate slowly. The rinsing liquid is sprayed out of the rinsing tank 12 to rinse the cleaning liquid remaining on the surface of the diode, so that the rinsing liquid comes into full contact with the surface of the diode and achieves a better rinsing effect.

[0047] After rinsing, turn off the second motor 42, lift the first holding device 5 using the lifting device 3, start the drive device 22, move the first holding device 5 above the unloading device 82, and place the first holding device 5 on the unloading device 82 using the lifting device 3, and then proceed with the next processing operation on the diode after cleaning.

[0048] Please refer to the following: Figure 2 and Figure 4 The driving device 22 includes a first motor 221 and a threaded rod 222. The first motor 221 is installed inside the support frame 21. The threaded rod 222 passes through the slider 23 and is threadedly connected to the slider 23. One end of the threaded rod 222 is fixedly installed at the output end of the second motor 42, and the other end of the threaded rod 222 is rotatably connected to the support frame 21.

[0049] When in operation, the first motor 221 is started, and the output end drives the threaded rod 222 to rotate. The threaded rod 222 drives the slider 23 to move horizontally. The slider 23 drives the lifting device 3 to move horizontally. The lifting device 3 drives the first holding device 5 to move through the protective shell 41 and the transmission shaft 43, so as to achieve the purpose of horizontal transportation of the first holding device 5 and the diode inside.

[0050] Please refer to the following: Figure 4 The horizontal transport device 2 further includes a chute 211 and a slide rod 24. The chute 211 is formed on the support frame 21. The slide rod 24 passes through the slider 23 and is installed in the chute 211. The slider 23 is slidably connected in the chute 211.

[0051] During operation, after the first motor 221 is started, the slider 23 slides along the slide rod 24 inside the slide groove 211. The slide groove 211 and the slide rod 24 achieve the purpose of limiting the slider 23, while the slide rod 24 supports the slider 23 and the lifting device 3.

[0052] Please refer to the following: Figure 2 and Figure 4 The first holding device 5 includes a first cleaning frame 51 and a fixing rod 52. The fixing rod 52 is fixedly installed on the top of the first cleaning frame 51 and is slidably connected inside the transmission shaft 43. The transmission device 4 also includes a first bolt 44, which passes through the transmission shaft 43 and the fixing rod 52 and is threadedly connected to the transmission shaft 43.

[0053] During operation, the diode to be cleaned is placed in the first cleaning frame 51. When it is necessary to move the first cleaning frame 51, the fixing rod 52 is inserted into the drive shaft 43, and the first bolt 44 is inserted through the fixing rod 52 and the drive shaft 43 and then rotated so that the first bolt 44 is threadedly connected to the drive shaft 43, thereby achieving the purpose of fixing the first cleaning frame 51.

[0054] Second Embodiment

[0055] Please refer to the following: Figure 5 and Figure 6The surface treatment apparatus for diode processing also includes a connecting structure 6 and a plurality of second holding devices 7. The connecting structure 6 is mounted on the drive shaft 43. When the lifting device 3 enters the ready state, the plurality of second holding devices 7 are assembled with the connecting structure 6.

[0056] When there are many diodes to be cleaned, they may stack, resulting in a poorer cleaning effect for the diodes located in the middle. In this embodiment, a certain number of diodes are placed in each of the multiple second holding devices 7. After the multiple second holding devices 7 are assembled onto the connecting structure 6, the output end of the lifting device 3 drives the protective shell 41 and the transmission shaft 43 to move up and down. The transmission shaft 43 drives the diodes inside the second holding devices 7 to move through the connecting structure 6. At the same time, the second motor 42 is started, and its output end drives the transmission shaft 43 to rotate. The transmission shaft 43 drives the diodes inside the second holding devices 7 to rotate through the connecting structure 6, thus cleaning the diodes. By setting multiple second holding devices 7 to distribute the diodes, stacking of diodes when there are many diodes is avoided, which would affect the cleaning effect.

[0057] Please refer to the following: Figure 6 and Figure 7 The connecting structure 6 includes a connecting rod 61 and a second bolt 62. The connecting rod 61 is fixedly installed on the transmission shaft 43. The connecting rod 61 is configured in a cross shape. Each end of the connecting rod 61 is threaded with the second bolt 62.

[0058] In this embodiment, the connecting rod 61 is cross-shaped and is fixedly installed on the drive shaft 43. During cleaning, multiple second holding devices 7 are assembled on the connecting rod 61, and the second holding devices 7 are limited and fixed by the second bolt 62. When the lifting device 3 and the second motor 42 are started, the drive shaft 43 drives the connecting rod 61 and the assembled second holding devices 7 to move, so as to drive the diode to move up and down and rotate at the same time.

[0059] Please refer to the following: Figure 7 The second holding device 7 includes a second cleaning frame 71 and a U-shaped block 72. The U-shaped block 72 is fixedly installed on the top of the second cleaning frame 71. The U-shaped block 72 is engaged with the connecting rod 61. The second bolt 62 passes through the U-shaped block 72 and is threadedly connected to the connecting rod 61.

[0060] During operation, when the second cleaning frame 71 needs to be assembled onto the connecting rod 61, the U-shaped block 72 at the top of the second cleaning frame 71 is engaged with the connecting rod 61, and the second bolt 62 is inserted through the U-shaped block 72 and rotated so that the second bolt 62 is threadedly connected to the connecting rod 61, thereby achieving the purpose of limiting and fixing the second cleaning frame 71.

[0061] The working principle of the surface treatment device for diode processing provided by this utility model is as follows:

[0062] During operation, after the diode to be cleaned is placed in the first cleaning frame 51, the fixing rod 52 is inserted into the drive shaft 43. The first bolt 44 is then passed through the fixing rod 52 and the drive shaft 43 and rotated to thread the bolt 44 onto the drive shaft 43. The lifting device 3 is then activated, and its output end lifts the protective shell 41. The protective shell 41, via the drive shaft 43, lifts the first cleaning frame 51. The first motor 221 is then activated, and its output end drives the slider 23 to move horizontally via the threaded rod 222. The slider 23 then drives the lifting device 3 to move horizontally. The lifting device 3 drives the first cleaning frame 51 to move via the protective shell 41 and the drive shaft 43. When the first cleaning frame 51 moves above the cleaning tub 11, the first motor 221 stops working, and the lifting device 3 is started. The output end drives the protective shell 41 and the drive shaft 43 to descend. The drive shaft 43 drives the first cleaning frame 51 down into the cleaning tub 11 to soak and clean the diodes. During cleaning, the second motor 42 is started, and the output end drives the drive shaft 43 to rotate slowly. The drive shaft 43 drives the first cleaning frame 51 and the diodes inside to rotate. When the lifting device 3 is activated, the output end drives the first cleaning frame 51 to move continuously up and down through the protective shell 41 and the drive shaft 43, so that the diode moves up and down and rotates simultaneously, ensuring that the cleaning fluid fully contacts the surface of the diode, while preventing contaminants from settling on the diode surface, thus achieving a better cleaning effect. After cleaning, the second motor 42 is turned off, and the first cleaning frame 51 is transported from the cleaning tank 11 to the rinsing tank 12 through the lifting device 3 and the first motor 221. The second motor 42 and the lifting device 3 are activated again, so that the first cleaning frame 51 rotates slowly while moving up and down, ensuring that the rinsing fluid fully contacts the surface of the diode, thus achieving a better rinsing effect. A connecting rod 61 and a second cleaning frame 71 are set up, and multiple second cleaning frames 71 are assembled onto the connecting rod 61 through U-shaped blocks 72. After the lifting device 3 and the second motor 42 are activated, the connecting rod 61 and the assembled second cleaning frames 71 are moved through the drive shaft 43. By setting multiple second cleaning frames 71, the diodes are placed separately, avoiding stacking when there are many diodes, which would affect the cleaning effect.
