[0017] By adopting the above technical solution, the blanking bin provides a centralized and unified collection space, making the subsequent processing of the cleaned circuit boards more convenient.

[0018] Further, a plurality of installation grooves are provided, and the plurality of installation grooves are arranged at equal intervals in a linear array.

[0019] By adopting the above technical solution, the installation grooves enable multiple circuit boards to be processed simultaneously on the conveyor belt, greatly improving the production efficiency.

One of the spring telescopic rods 5 is fixedly connected to a first clamping block 6. An inclined surface 7 is arranged on the top of the first clamping block 6. The other spring telescopic rod 5 is fixedly connected to a second clamping block 8;

[0033] Bases 1 are arranged on both sides of the conveyor belt 3. A blanking baffle 9 is arranged on one side of the base 1. The blanking baffle 9 is adapted to the first clamping block 6. The spring telescopic rod 5 has a certain elasticity and can adapt to circuit boards of different thicknesses, ensuring that the clamping block can firmly clamp the circuit board without causing excessive pressure on the circuit board. The conveyor belt 3 enables the circuit board to continuously and smoothly pass through the cleaning area, realizing the automatic processing of the circuit board and greatly improving the production efficiency.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the height of the inclined surface 7 at the top of the first clamping block 6 is slightly higher than the outer surface of the conveyor belt 3. The height of the top of the second clamping block 8 is lower than the outer surface of the conveyor belt 3. The height of the inclined surface 7 being slightly higher than the outer surface of the conveyor belt 3 can effectively enable the blanking baffle 9 to more easily push the first clamping block 6 to realize the automatic blanking of the circuit board. The height of the top of the second clamping block 8 being lower than the outer surface of the conveyor belt 3 effectively avoids the blanking baffle 9 squeezing the second clamping block 8 and thus squeezing the circuit board, causing damage to the circuit board.

[0035] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the plasma cleaner 2 includes a radio frequency power supply 201. An air inlet 204 is arranged on the outer surface of the radio frequency power supply 201. A spray pipe 202 is arranged on the top of the radio frequency power supply 201. A plasma generator 203 is arranged on the top of the spray pipe 202. The plasma generator 203 contains special electrodes and gas channels inside, and can excite gas molecules into plasma under the action of a high-frequency electric field. The spray pipe 202 enables the plasma to be evenly sprayed onto the surface of the circuit board.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 , two plasma cleaners 2 are provided. The two plasma cleaners 2 are symmetrically arranged along the central axis of the conveyor belt 3. The plasma cleaner 2 can generate plasma. This high-energy substance can effectively remove pollutants on the surface of the circuit board, such as oil stains, oxides, etc., so as to achieve efficient and non-damaging cleaning of the circuit board. The two symmetrically arranged plasma cleaners 2 can clean both sides of the circuit board simultaneously, improving the cleaning efficiency. Embodiment

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 , a fixing block 10 is provided below the blanking baffle 9. A chute 11 is opened on one side of the fixing block 10. A slider 12 is engaged and slidably mounted in the chute 11. The fixing block 10 provides a stable support and fixing point for the blanking bin 13, preventing the blanking bin 13 from shaking or tilting, so as to ensure that the circuit board can accurately fall into it. The chute 11 is opened on one side of the fixing block 10 and cooperates with the slider 12 to realize the sliding installation and disassembly of the blanking bin 13.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 , one side of the slider 12 is fixedly connected to the blanking bin 13. A handle 14 is provided on the outer surface of the blanking bin 13. The blanking bin 13 provides a centralized collection space, making the subsequent processing of the cleaned circuit board more convenient. The handle 14 makes the removal and installation of the blanking bin 13 more convenient.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , a number of installation slots 4 are provided. The number of installation slots 4 are arranged in a linear array at equal intervals and evenly. The installation slots 4 enable multiple circuit boards to be processed simultaneously on the conveyor belt, greatly improving the production efficiency. The equally spaced and evenly arranged installation slots 4 ensure that each circuit board can receive the same treatment during the cleaning process, ensuring the consistency and uniformity of the cleaning.

[0040] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , four bases 1 are provided. The four bases 1 are arranged in a rectangular array. An anti-corrosion coating is provided on the outer surface of the base 1. The four bases 1 arranged in a rectangular array provide stable and uniform support for the entire device. The setting of the anti-corrosion coating effectively protects the base 1 from corrosion and rust.

[0041] The implementation principle of the present utility model is as follows: First, place the circuit board in the installation groove 4 and clamp the circuit board through the first clamping block 6 and the second clamping block 8. Then, the circuit board moves with the conveyor belt 3 to the lower part of the plasma generator 203, and the nozzle 202 bombards the surface of the circuit board with plasma to complete the cleaning of both sides of the circuit board. After that, as it moves with the conveyor belt 3, the blanking baffle 9 presses the inclined surface 7, increasing the gap between the first clamping block 6 and the second clamping block 8, causing the cleaned circuit board to fall into the blanking bin 13. When it is necessary to take out the circuit board in the blanking bin 13, the operator can hold the bottom of the blanking bin 13 with one hand and pull the handle 14 with the other hand to slide the slider 12 out of the chute 11, remove the blanking bin 13 and carry it away.
