Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0050] Example 1

[0051] Reference Figure 1-Figure 8 A surface flushing device for circuit board production in this embodiment includes a cleaning box 1, and a bracket 2 is fixedly installed at the bottom of each side of the cleaning box 1 to support the entire device. Inside the cleaning box 1, a filter screen plate 3 is slidably arranged along its length direction. One side of the filter screen plate 3 extends to the outside of the cleaning box 1 for easy cleaning and replacement. The setting of the filter screen plate 3 can effectively filter impurities in the flushing process and keep the board washing water clean.

[0052] At the bottom of one side of the cleaning box 1, a booster pump 4 is fixedly installed, the water suction end of the booster pump 4 extends into the cleaning box 1, and the water outlet end is connected to a delivery pipe 5, which extends along the side wall of the cleaning box 1 to the inside and is located above the filter plate 3. The delivery pipe 5 is fixedly connected to the side wall of the cleaning box 1 to ensure its stability. Inside the delivery pipe 5, a connecting pipe 6 is tightly and slidably connected, and one end of the connecting pipe 6 extends to the inside of the cleaning box 1 and is connected to a nozzle assembly.

[0053] The spray head assembly consists of an installation box 7, which is fixedly installed on the first adjustment mechanism. The specific structure of the first adjustment mechanism here is described later. One end of the connecting pipe 6 extends into the interior of the installation box 7 and is fixedly connected to the inner wall of one side of the installation box 7. An electric push rod 8 is installed at the bottom of the installation box 7. The output shaft of the electric push rod 8 is connected to the bottom of a spray plate 14. The spray plate 14 is located inside a closed cover 12. An outer tube 11 is fixed on the top of the closed cover 12. The outer tube 11 is slidably mounted on the support tube 9. The support tube 9 passes through the top of the installation box 7 and extends to the inside of the cleaning box 1. The outer tube 11 is connected to the inner tube 10, and the inner tube 10 slides in the support tube 9, thereby realizing the lifting and lowering adjustment of the spray plate 14. A retaining ring 13 is fixed at the bottom of the closed cover 12, and a plurality of drainage holes 15 are evenly spaced on the side to facilitate the discharge of plate washing water.

[0054] The first adjustment mechanism is used to adjust the position of the nozzle assembly. One side of the adjustment mechanism passes through the adjustment hole of the cleaning box 1, extends to the outside of the cleaning box 1, and is connected to the top of the other side of the cleaning box 1 to form a stable sliding support. Through the first adjustment mechanism, the position of the nozzle assembly in the cleaning box 1 can be flexibly adjusted to adapt to circuit board bodies 29 of different sizes and positions.

[0055] The support mechanism is installed above the cleaning box 1 to support the circuit board body 29. The support mechanism is used to fix the circuit board body 29. The second adjustment mechanism is installed on the support mechanism to adjust the position of the circuit board body 29 in the horizontal or vertical direction so as to accurately align the nozzle assembly for flushing.

[0056] During use, first fix the circuit board body 29 on the supporting mechanism and adjust its position through the second adjusting mechanism. Then, start the booster pump 4 to pump out the board washing water in the cleaning box 1 and deliver it to the nozzle assembly through the delivery pipe 5 and the connecting pipe 6. At this time, the electric push rod 8 drives the spray plate 14 and the closing cover 12 to rise to the position in contact with the circuit board body 29. The spray plate 14 sprays the board washing water to rinse the circuit board body 29. During the rinsing process, the board washing water is discharged from the drainage hole 15 of the closing cover 12, falls on the filter screen plate 3, and is recycled after filtration.

[0057] Through the above design, the surface flushing device for circuit board production in this embodiment can achieve accurate and efficient flushing of the circuit board body 29, while reducing the waste of washing water and the diffusion of impurities.

[0058] First, inside the cleaning box 1, two first limit rods 17 are symmetrically fixed and installed. The two limit rods ensure the stable sliding of the support frame 16 in the horizontal direction. Slide grooves are respectively provided on both sides of the support frame 16, so that the two first limit rods 17 can be respectively inserted into and slide along the inner walls of the slide grooves. The mounting box 7 is fixedly connected to the support frame 16. Therefore, when the support frame 16 slides horizontally in the cleaning box 1, the mounting box 7 and the nozzle assembly thereon will also move accordingly. This design allows the flushing position of the closure cover 12 to be conveniently adjusted according to the specific position of the circuit board body 29 during actual use to achieve precise flushing.

[0059] At the top of the other side of the cleaning box 1, a mounting frame 18 is fixedly installed, and two sliding holes are provided on it for the clamping plates 20 to slide through. The two clamping plates 20 are respectively located on both sides of the support frame 16, and limit strips 21 are fixedly installed on the side close to each other. These limit strips 21 can extend into the slide groove of the support frame 16 to form a clamp with the inner wall of the slide groove, thereby realizing the braking and limiting of the support frame 16. The bottom of the mounting frame 18 is rotatably connected to an adjusting rod 19, and the adjusting rod 19 is provided with two sections of thread grooves 191 with opposite thread directions, which are respectively threadedly connected to the two clamping plates 20. When the position of the mounting box 7 needs to be fixed, it is only necessary to rotate the adjusting rod 19, and the two clamping plates 20 are brought close to each other through thread transmission until the limit strips 21 tightly clamp the slide groove of the support frame 16, so as to achieve accurate positioning of the flushing position.

[0060] A fixed frame 22 is fixedly installed on the cleaning box 1, and two movable plates 23 are slidably connected to the inner walls of the two sides thereof. A bracket 27 is fixedly installed on the inner side of each movable plate 23, and a plurality of stop wheels 28 are symmetrically rotatably connected to the inner wall of the bracket 27 for clamping and supporting the circuit board body 29. A fastening assembly is installed on the top outer side of the movable plate 23, which consists of a connecting plate 25, an adjusting nut 26 and an adjusting screw 24. The connecting plate 25 is fixed on the movable plate 23, and the adjusting nut 26 is fixed on one side of the connecting plate 25. The adjusting screw 24 is rotatably connected to one side of the fixed frame 22 and penetrates the adjusting nut 26 and the connecting plate 25. By rotating the adjusting screw 24 and utilizing the threaded transmission between the adjusting screw 24 and the adjusting nut 26, the connecting plate 25 and the movable plate 23 can be pushed to slide along the fixed frame 22, thereby adjusting the distance between the two brackets 27 to adapt to circuit board bodies 29 of different widths.

[0061] In actual use, the circuit board body 29 is first passed through the fixing frame 22, and is clamped and supported by the stopper wheel 28. Then, according to the width of the circuit board body 29, the connecting plate 25 and the moving plate 23 are driven to slide along the fixing frame 22 by rotating the adjusting screw 24 until the distance between the two brackets 27 matches the width of the circuit board body 29. At this time, the circuit board body 29 is stably supported on the bracket 27, which is convenient for subsequent flushing operations.

[0062] On one side of the top of the fixing frame 22, a limiting plate 39 is fixedly installed, and two L-shaped rods 40 are symmetrically penetrated and slidably connected on the limiting plate 39. The two L-shaped rods 40 can slide freely on the limiting plate 39. A plurality of card slots 41 are evenly spaced at the top of the L-shaped rod 40 for subsequent positioning and fixing. One end of the L-shaped rod 40 is connected to a pull rod 42. By pulling or pushing the pull rod 42, the two L-shaped rods 40 can be moved synchronously. The other end of the L-shaped rod 40 is fixedly connected to an L-shaped positioning plate 32, which is used to support and position the circuit board body 29.

[0063] Two slide bars 31 are symmetrically fixedly installed on the top of the L-shaped positioning plate 32, and two second limit rods 30 are slidably connected to the two slide bars. The four second limit rods 30 are symmetrically fixedly installed on both sides of the fixing frame 22 to ensure the stability of the L-shaped positioning plate 32 during movement.

[0064] On one side of the top of the L-shaped positioning plate 32, a fixing plate 33 is fixedly installed, and two moving rods 34 are symmetrically penetrated and slidably connected on the fixing plate 33. One end of the two moving rods 34 is commonly connected to a linkage plate 35. At the top of the fixing plate 33, a fixing nut 38 is rotatably connected, and a fixing screw 37 is fixedly connected to the top of one side of the linkage plate 35. One end of the fixing screw 37 penetrates the fixing nut 38 and is rotatably connected to the top of one side of the L-shaped support plate 36. The bottom of the L-shaped support plate 36 extends to the bottom of the L-shaped positioning plate 32, and is used to cooperate with the L-shaped positioning plate 32 to clamp the circuit board body 29.

[0065] After the circuit board body 29 is initially limited by the two brackets 27, it can be inserted into the L-shaped positioning plate 32. Subsequently, by rotating the fixing nut 38 and utilizing the threaded transmission between it and the fixing screw 37, the fixing screw 37 and the linked plate 35 and the moving rod 34 connected thereto can be driven to move laterally, thereby pushing the L-shaped bracket 36 closer to the circuit board body 29 to achieve its clamping and positioning.

[0066] At the same time, by pulling or pushing the pull rod 42, the two L-shaped rods 40 and the L-shaped positioning plates 32 connected thereto can be driven to move laterally, thereby adjusting the position of the circuit board body 29 on the fixing frame 22 to meet different flushing requirements.

[0067] A support plate 43 is fixedly installed on the top of the fixed frame 22, and a support shaft 44 is fixedly installed on the support plate 43. Two rotating arms 45 are symmetrically rotatably mounted on the support shaft 44, and a clamping rod 47 is fixedly installed on the two rotating arms 45. When it is necessary to fix the position of the L-shaped rod 40 and the L-shaped positioning plate 32, the clamping rod 47 can be aligned and clamped into the clamping groove 41 at the top of the L-shaped rod 40.

[0068] In order to provide the support arm 45 with the function of resetting and maintaining tension, two torsion springs 46 are symmetrically mounted on the support shaft 44, and the two ends of the two torsion springs 46 are respectively fixedly connected to one side of the support plate 43 and one side of the rotating arm 45. After adjusting the position of the circuit board body 29, the two rotating arms 45 are released. At this time, the torsion spring 46 in a stressed state will drive the rotating arm 45 to rotate automatically until the clamping rod 47 is clamped into the corresponding clamping groove 41, thereby fixing the L-shaped rod 40 and the L-shaped positioning plate 32, thereby ensuring the stability of the circuit board body 29 during the flushing process.

[0069] The present invention provides a method for using a surface flushing device for circuit board production, comprising the following steps:

[0070] S1, insert the circuit board body 29 into the two brackets 27 and the L-shaped positioning plate 32 respectively;

[0071] S2. The two adjusting screws 24 are rotated respectively, and the connecting plate 25 can be driven to move under the thread transmission of the corresponding adjusting nuts 26. At this time, the bracket 27 can be driven to move horizontally through the moving plate 23, so that the width of the two brackets 27 can be adjusted according to the width of the circuit board body 29, so as to facilitate the support of the circuit board body 29;

[0072] S3, rotating the fixing nut 38, under the action of the thread transmission with the fixing screw 37, can drive the fixing screw 37 to move horizontally, thereby driving the L-shaped support plate 36 to move, and using the L-shaped support plate 36 to clamp and position the circuit board body 29;

[0073] S4. Pushing or pulling the pull rod 42 can drive the two L-shaped rods 40 to move, thereby driving the L-shaped positioning plate 32 to move horizontally, so that the position of the circuit board body 29 can be adjusted. After the position adjustment of the circuit board body 29 is completed, the two rotating arms 45 can be released, and the two torsion springs 46 in a stressed state can drive the corresponding rotating arms 45 to rotate, so that the clamping rod 47 and the corresponding two clamping slots 41 can be used for clamping, and the two L-shaped rods 40 can be positioned, so that the circuit board body 29 can be positioned;

[0074] S5, pull the support frame 16 to adjust the position of the closed cover 12, so that the closed cover 12 corresponds to the position to be cleaned of the circuit board body 29. After the position of the closed cover 12 is adjusted, the adjusting rod 19 can be rotated, and the two clamping plates 20 can be brought close to each other by the threaded transmission of the two-section thread groove 191 and the corresponding clamping plate 20. After the limit bar 21 is moved into the corresponding slide groove, the slide groove can be clamped by the limit bar 21, so that the support frame 16 can be braked and limited, so that the position of the closed cover 12 can be positioned;

[0075] S6, start the electric push rod 8 to drive the spray plate 14 to move upward, so that the sealing cover 12 contacts the circuit board body 29;

[0076] S7, start the booster pump 4 to pump out the board washing water in the cleaning box 1, and then transport it to the installation box 7 through the delivery pipe 5 and the connecting pipe 6, and then spray it through the support pipe 9, the inner pipe 10 and the spray plate 14, so that the circuit board body 29 can be washed, and the sealing cover 12 keeps in contact with the circuit board body 29, which can prevent the board washing water from splashing everywhere, and the sprayed board washing water can be discharged from the multiple drainage holes 15 and fall on the filter screen plate 3, at this time, the impurities in the board washing water can be filtered;

[0077] S8. Finally, when the filter screen plate 3 is pulled, the filtered impurities can be cleaned.

[0078] However, as is well known to those skilled in the art, the working principles and wiring methods of the booster pump 4 and the electric push rod 18 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
