During the production and processing of circuit boards, washing and drying equipment is required to clean and dry them.

[0003] However, in the existing washing and drying equipment, the circuit board is usually rinsed with cleaning solution during use. Even after rinsing, some small impurities may still remain on the surface of the circuit board. These residues may be grease and dust, which affect the quality of the circuit board.

[0004] If a flexible brush is used to clean the surface of the circuit board, oil and impurities are likely to remain on the surface of the cleaning solution. During the process of lifting the circuit board above the liquid surface, the remaining oil and impurities are likely to adhere to the circuit board, causing secondary pollution and affecting the cleaning effect.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] This embodiment addresses the problem in existing washing and drying devices where, during use, the circuit board is typically rinsed with cleaning fluid. However, even after rinsing, some small impurities may remain on the circuit board surface, such as grease and dust, affecting the quality of the circuit board.

[0029] Please see Figure 1 - Figure 4 As shown, this embodiment is an integrated washing and drying device for circuit boards used in the production of electrical instruments and meters. It includes a fixed frame 1, and a support plate 101 and a cleaning component 2 are movably installed inside the fixed frame 1. There is a moving gap between the two ends of the support plate 101 and the inner wall of the fixed frame 1. The moving gap is used to prevent the rotating shaft 201, the liquid extraction pipe 206 and the hot air blower 110 from blocking the support plate 101 when the support plate 101 moves.

[0030] The fixed frame 1 is movably installed with lead screw 106 and lead screw 2 107. Lead screw 106 and lead screw 2 107 are connected by belt drive. Both lead screw 106 and lead screw 2 107 are movably connected with rotating nuts 108 by threads. The rotating nuts 108 are fixedly connected to both sides of the support plate 101. The bottom of the fixed frame 1 is fixedly installed with motor 2 109. The output end of motor 2 109 is fixedly connected to lead screw 106.

[0031] In actual use, the motor 109 drives the lead screw 106 to rotate, and the lead screw 107 rotates synchronously with the lead screw 106. At this time, the rotating nut 108 moves on the lead screw 106 and the lead screw 107 under the action of the thread, thereby driving the support plate 101 to move. Both the lead screw 1 and the lead screw 2 are threaded, but they are not shown in the figure.

[0032] A hot air blower 110 is fixedly installed inside the fixed frame 1. The hot air blower 110 is located above the cleaning component 2. Multiple hot air blowers 110 are provided. The cleaning component 2 includes a rotating shaft 201 and a moving block 202. Slide grooves 102 are opened on both sides of the fixed frame 1. Slide rails 103 are fixedly installed on both sides of the fixed frame 1. The moving block 202 is movably installed on the slide rails 103. After cleaning, the support plate 101 is raised to be flush with the bottom of the hot air blower 110. The hot air blowers 110 on both sides are started to dry the circuit board. After drying, the support plate 101 is raised again to unload the circuit board.

[0033] A motor 204 is fixedly mounted on the top of the movable block 202. A rotating shaft 201 is movably mounted in the slide groove 102. The output end of the motor 204 is fixedly connected to the rotating shaft 201. A flexible brush 205 is fixedly mounted on the rotating shaft 201. A gear 209 is fixedly mounted on the rotating shaft 201 and is positioned close to the motor 204. A rack 210 is fixedly mounted on the top of the slide rail 103. The rack 210 meshes with the gear 209. When the motor 204 drives the rotating shaft 201 to rotate, the gear 209 rotates accordingly. By utilizing the cooperation of the rack 210 and the gear 209, the movable block 202 is driven to slide on the slide rail 103.

[0034] The support plate 101 has multiple positioning grooves 104, which are evenly spaced on the support plate 101. Multiple drainage grooves 105 are provided in the positioning grooves 104. The multiple positioning grooves 104 enable multi-station cleaning of the circuit board, while ensuring the stability of the circuit board during cleaning. The drainage grooves 105 at the bottom ensure that water droplets on the surface of the circuit board fall off smoothly after cleaning.

[0035] The circuit board to be cleaned is placed on the support plate 101. The support plate 101 is moved to below the liquid surface in the fixing frame 1. The circuit board is initially cleaned with the cleaning solution. Then, the support plate 101 is moved to the liquid surface. The motor 204 is started, which drives the rotating shaft 201 to rotate. Through the sliding of the moving block 202, the flexible brush 205 is used to brush the circuit board on the support plate 101, effectively cleaning the impurities adhering to the circuit board and thus improving the quality of the circuit board.

[0036] Example 2:

[0037] This embodiment addresses the problem that when a flexible brush is used to clean the surface of a circuit board, oil and impurities easily remain on the surface of the cleaning solution. During the process of lifting the circuit board above the liquid surface, the residual oil and impurities easily adhere to the circuit board, causing secondary pollution and affecting the cleaning effect.

[0038] Please see Figure 5 - Figure 6 As shown, this utility model also includes a connecting plate 203, which is fixedly installed on one side of the moving block 202. A liquid extraction pipe 206 is fixedly installed at the end of the connecting plate 203. A box 3 is fixedly installed on one side of the fixing frame 1. The liquid extraction pipe 206 is fixedly connected to the box 3 through a pipeline 207. A pipeline 208 is fixedly installed on the side of the box 3 away from the fixing frame 1. One end of the pipeline 208 extends into the interior of the fixing frame 1.

[0039] A filter plate 301 is fixedly installed inside the housing 3. Pipeline 207 is located above the filter plate 301, and pipeline 208 is located below the filter plate 301. Multiple water pumps are also fixedly installed in the housing 3, which are connected to pipeline 207 or pipeline 208 respectively. They are used to draw the cleaning solution using the suction pipe 206 and to transport the purified cleaning solution through pipeline 208. After passing through pipeline 207, the cleaning solution enters the housing 3 and falls onto the filter plate 301, thereby filtering the cleaning solution. The water pumps are not shown in the figure.

[0040] Pipeline 207 is a rubber hose, and its length is adaptable. As the liquid extraction tube 206 moves, pipeline 207 moves and extends accordingly.

[0041] While the flexible brush 205 is brushing the circuit board, the liquid extraction pipe 206 moves synchronously with the moving block 202. During the brushing, the liquid extraction pipe 206 and pipeline 1 207 are used to extract impurities on the liquid surface into the box 3. After filtration and purification, the liquid is then transported back to the fixed frame 1 by pipeline 208. This completes the purification of the cleaning solution, avoids secondary contamination of the circuit board, and effectively improves the cleaning effect.

[0042] Combining Embodiment 1 and Embodiment 2, the rotating shaft 201 and the moving block 202 work together. The motor 204 drives the rotating shaft 201 to rotate, and the moving block 202 slides, using the flexible brush 205 to brush the circuit board on the support plate 101, effectively cleaning the impurities adhering to the circuit board and thus improving the quality of the circuit board. At the same time, the liquid extraction pipe 206 and the box 3 work together, using the liquid extraction pipe 206 and the pipeline 207 to extract the impurities on the liquid surface into the box 3. After filtration and purification, the impurities are then transported back to the fixed frame 1 by the pipeline 208, thus completing the purification of the cleaning solution, avoiding secondary contamination of the circuit board and effectively improving the cleaning effect.

[0043] The working process and principle of this utility model are as follows:

[0044] First, the rotating shaft 201 is driven to rotate by the motor 204. Through the sliding of the moving block 202, the flexible brush 205 is used to brush the circuit board on the support plate 101, effectively cleaning the impurities stuck to the circuit board and thus improving the quality of the circuit board.

[0045] Furthermore, the impurities on the liquid surface are drawn into the box 3 using the suction pipe 206 and the first pipeline 207. After filtration and purification, the liquid is then transported back to the fixed frame 1 by the second pipeline 208. This completes the purification of the cleaning solution, avoids secondary contamination of the circuit board, and effectively improves the cleaning effect.

[0046] In summary, this utility model, through the cleaning component 2, not only thoroughly cleans the circuit board but also cleans the surface of the cleaning solution.

[0047] The above description is merely an example and illustration of the structure of the present invention.
