Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and more specifically, to an integrated cleaning and drying device for circuit board processing. Background Art

[0002] During the initial processing of the circuit board, it is necessary to clean and dry the circuit board. The prior art generally integrates the dryer in the post-cleaning stage to make it more convenient to transfer the circuit board. Since the initially processed circuit board is relatively wide and has a relatively low flatness, after the circuit board is cleaned, some cleaning liquid will accumulate and remain on the side of the circuit board. After the circuit board is transported from the cleaning machine to the dryer by the conveyor roller, the dryer needs to dry a large amount of cleaning liquid accumulated on the side of the circuit board, which is inefficient. At the same time, during the operation of the dryer, the hot air inside it will flow into the cleaning machine, causing heat loss, which is not conducive to energy conservation and emission reduction. Summary of the invention

[0003] In order to overcome the disadvantages that a large amount of cleaning liquid accumulates on the side of the circuit board, resulting in low drying efficiency, and hot air in the dryer flows into the cleaning machine, causing heat loss, the present invention provides an integrated cleaning and drying device for circuit board processing.

At the same time, the mesh cloth can intercept and absorb the blown water droplets to prevent them from splashing onto the already dried circuit board on the left. At the same time, the obliquely symmetrically distributed mesh cloth can also intercept the hot air in the dryer, that is, it reduces the size of the air flow channel, which is conducive to reducing the probability of the hot air in the dryer flowing to the frame, thereby improving the hot air interception effect and further reducing heat loss.

[0031] The box body 2 also includes a guide plate 203 ; the guide plate 203 is welded on the box body 2 , and the guide plate 203 is tilted toward the cleaning machine 1 , so that the liquid inside the box body 2 is guided into the cleaning machine 1 through the guide plate 203 .

[0034] A pressing plate 208 is also included; each airbag 7 is fixedly connected to a pressing plate 208, and the pressing plate 208 cooperates with the movable block 206 to squeeze the airbag 7 in all directions.

[0035] The working principle of the above embodiment is as follows:

[0036] First, the circuit board to be cleaned is placed on the electric conveying roller group on the right side of the cleaning machine 1 through the external conveying mechanism, and then the circuit board is driven to move to the left by the electric conveying roller group, so that the circuit board passes through the frame 4 and the dryer 3 to the left in turn, and finally moves to the electric conveying roller group on the left side of the cleaning machine 1, and then is taken out by the electric conveying roller group. During this process, the electric slide rail 201 and the electric slider 202 are started, so that the electric slider 202 slides back and forth on the electric slide rail 201, and the electric slider 202 drives the frame 4 to reciprocate within fifteen degrees, and the frame 4 drives the electric conveying roller group inside it to reciprocate within fifteen degrees. When the electric conveying roller group inside the frame 4 rotates to the extreme position, its highest point is still lower than the electric conveying roller group in the cleaning machine 1, and its lowest point is still higher than the electric conveying roller group in the dryer 3, so that the circuit board can move smoothly to the left between the three different electric conveying roller groups, and the circuit board passes through the cleaning machine During the process of cleaning the circuit board in the cleaning machine 1, the cleaning machine 1 sprays and cleans the circuit board. During the process of the circuit board passing through the drying machine 3, the drying machine 3 dries the circuit board. When the circuit board moves to the electric conveying roller group on the frame 4, the electric conveying roller group on the frame 4 drives the circuit board to rotate back and forth, thereby pouring out the cleaning liquid collected on the side of the circuit board, and then the circuit board is transported to the drying machine 3 for drying, which effectively avoids the problem of low drying efficiency caused by a large amount of cleaning liquid collected on the side of the circuit board. When the cleaning liquid is poured out from the circuit board, the cleaning liquid is poured into the upper side of the guide plate 203. Since the guide plate 203 is tilted toward the cleaning machine 1, the cleaning liquid will flow back to the cleaning machine 1 along the upper surface of the guide plate 203, so that this part of the cleaning liquid re-participates in the spraying cycle to avoid wasting the cleaning liquid. In this process, the cleaning liquid is intercepted by the baffle 204 located at the left end of the guide plate 203 to prevent it from flowing into the drying machine 3.

[0037] During the reciprocating rotation of the frame 4, the front and rear sides of the frame 4 will alternately squeeze the two airbags 7. When the airbags 7 are squeezed, the gas in the airbags 7 flows into the cavity 1 91 through the pipe 10 and the one-way valve 11. Since the width of the nozzle 92 is much smaller than the width of the cavity 1 91, the gas first fills the cavity 1 91, and then is ejected obliquely to the left from the two nozzles 92 into the dryer 3. When the airbags 7 stop being squeezed, the airbags 7 rebound so that the gas in the dryer 3 flows into the airbags 7 through the pipe 1 8 and the one-way valve 1 9. In this process, the filter cartridge 2010 filters out the water vapor in the gas flowing through the pipe 1 8 to prevent the water vapor from condensing in the airbags 7. On the inner side of the airbag 7, that is, by utilizing the reciprocating frame 4, a circulating airflow is formed between the dryer 3 and the airbag 7. After the airflow is ejected obliquely to the left from the nozzle 92, an air curtain is formed at the left opening of the frame 4, which can prevent the hot air in the dryer 3 from escaping through the frame 4 and flowing into the cleaning machine 1, thereby greatly reducing the heat loss in the dryer 3. When in use, the frame 4, which is used to pour out the cleaning liquid collected on the side of the circuit board, is also used to cooperate with the airbag 7 to form an air curtain at the left opening of the frame 4, which can prevent the hot air in the dryer 3 from passing through the frame 4 and flowing into the cleaning machine 1, thereby greatly reducing the heat loss in the dryer 3.

[0038] If the rotation amplitude of the frame 4 is small, the squeezing effect on the airbag 7 is low, resulting in low air curtain strength, and further resulting in low hot air interception effect. If the rotation amplitude of the frame 4 is large, the highest point of the electric conveying roller group in the frame 4 will be higher than the electric conveying roller group in the cleaning machine 1, resulting in the circuit board being stuck when it is transferred from the cleaning machine 1 to the frame 4. Therefore, during the rotation of the frame 4, Figure 5 From the perspective shown in , the frame 4 drives the movable block 1 205 to move downward, and the movable block 1 205 drives the movable block 2 206 to move downward at the end away from the airbag 7, while the movable block 206 can only rotate around the rotating shaft on the connecting block 207, so that the movable block 206 close to the end of the airbag 7 moves upward, so that the movable block 206 pushes the pressure plate 208 to move upward, and the airbag 7 is squeezed by the pressure plate 208. In this process, since the connecting shaft between the movable block 206 and the connecting block 207 is close to the connection between the movable block 1 205 and the movable block 206, that is, by using the lever principle, the frame 4 only needs to drive the movable block 206 to move downward a relatively small distance at the end away from the airbag 7, and the movable block 206 close to the end of the airbag 7 can push the pressure plate 208 to move upward a relatively large distance, so that the airbag 7 can be fully squeezed to ensure the strength of the air curtain, thereby ensuring the hot air interception effect.

[0039] According to the above working principle, we know that the present invention has the following effects:

[0040] The frame 4 drives the circuit board to rotate back and forth, and the cleaning liquid collected on the circuit board is poured out before the drying operation is performed, which is beneficial to improving the drying efficiency. At the same time, the frame 4 used to pour out the cleaning liquid collected on the side of the circuit board is also used to cooperate with the air bag 7 to form an air curtain at the left opening of the frame 4, which can prevent the hot air in the dryer 3 from passing through the frame 4 and flowing into the cleaning machine 1, thereby greatly reducing the heat loss in the dryer 3. At the same time, the frame 4 only needs to drive the end of the movable block 206 away from the air bag 7 to move downward a relatively small distance, and the end of the movable block 206 close to the air bag 7 can push the pressure plate 208 to move upward a relatively large distance, so that the air bag 7 can be fully squeezed, avoiding the problem of low air curtain interception effect caused by the small rotation amplitude of the frame 4. Example 2

[0041] On the basis of Example 1, Figure 3 As shown, it also includes a mesh 209; three meshes 209 arranged downwardly inclined are fixedly connected to the upper part of the dryer 3, and another three meshes 209 arranged upwardly inclined are fixedly connected to the lower part of the dryer 3. The mesh 209 is set close to the partition 5, and the water droplets are absorbed by the mesh 209.

[0042] The outer surfaces of the cleaning machine 1, the housing 2 and the drying machine 3 are all coated with an anti-corrosion layer to prevent rust.

[0043] The working principle of the above embodiment is as follows:

[0044] After pouring out the cleaning liquid collected on the circuit board as described in Example 1:

[0045] There are still some water droplets remaining on the circuit board. At this time, the circuit board passes through the left opening of the frame 4 and moves toward the inside of the dryer 3. The air curtain sprayed from the nozzle 92 will blow to the surface of the circuit board, thereby blowing the water droplets remaining on the surface of the circuit board to the left to other circuit boards that have been dried on the left. Therefore, a mesh 209 is arranged on the inside of the dryer 3 to intercept and absorb the splashing water droplets to prevent them from splashing onto other circuit boards that have been dried on the left. At the same time, the mesh 209 with an oblique and symmetrical distribution can also intercept the hot air in the dryer 3, that is, the size of the airflow channel is reduced, which is beneficial to reducing the probability of the hot air in the dryer 3 flowing to the frame 4, thereby improving the hot air interception effect and further reducing heat loss.

[0046] According to the above working principle, we know that the present invention has the following effects:

[0047] The air curtain used to intercept hot air can also blow away the water droplets remaining on the circuit board, thereby improving the drying efficiency of the circuit board. At the same time, the blown water droplets are intercepted and absorbed by the mesh 209 to prevent them from splashing onto the already dried circuit board on the left. At the same time, the obliquely symmetrically distributed mesh 209 can also intercept the hot air in the dryer 3, that is, the size of the air flow channel is reduced, which is beneficial to reducing the probability of the hot air in the dryer 3 flowing to the frame 4, thereby improving the hot air interception effect and further reducing heat loss.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
