Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, and in particular to a board washing device for processing optical module circuit boards. Background Technology

[0002] Optical module circuit boards are key components in electronic devices. Their processing involves multiple stages, including design, manufacturing, assembly, and testing. During processing, various contaminants may be generated, such as resin residues, flux residues, oil stains, and dust. If these contaminants are not removed in time, they may negatively affect the performance and reliability of the circuit board. Cleaning the circuit board can remove contaminants generated during processing, ensuring that the surface of the circuit board is clean and tidy. This helps to improve the overall quality of the product and reduce circuit failures or malfunctions caused by contaminants.

[0003] Patent publication number CN221269118U discloses a circuit board cleaning machine that not only meets the basic needs of cleaning circuit boards, but also allows users to easily place or remove the cleaning structure into the cleaning device and quickly transfer the cleaned circuit board out of the cleaning device, thereby improving the efficiency of cleaning circuit boards.

[0004] However, the above solution still has some shortcomings in the implementation process. For example, the circuit boards are placed in the cleaning sieve tank and are in a close contact with each other, so they cannot fully contact the cleaning liquid, resulting in poor cleaning effect. At the same time, the circuit boards are also easily damaged due to friction between each other during the process of moving the cleaning sieve tank. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a board washing device for processing optical module circuit boards.

[0006] The technical implementation of this utility model is as follows: a board washing device for processing optical module circuit boards, including a base plate, a water tank, a valve pipe, an ultrasonic generator, a lifting assembly, a placement assembly, and a drying assembly. The water tank is fixedly connected to the top of the base plate. A valve pipe is provided on the front side of the water tank. An ultrasonic generator is embedded on the front side of the water tank. A lifting assembly is provided on the rear side of the water tank. A placement assembly for placing the circuit board to be cleaned is provided on the lifting assembly. A drying assembly for drying the circuit board is provided on the placement assembly. The lifting assembly is used to lift the placement assembly.

[0007] Furthermore, the lifting assembly includes a mounting base, an L-shaped sliding plate, a cylinder, and a crossbeam. Two mounting bases are fixedly connected at intervals to the rear side of the water tank, and L-shaped sliding plates are slidably mounted on both mounting bases. A cylinder is installed in the middle of the rear side of the water tank, and a crossbeam is fixedly connected between the upper parts of the two L-shaped sliding plates. The piston rod end of the cylinder is fixedly connected to the crossbeam.

[0008] Furthermore, the placement assembly includes a fixed plate, fixed rods, horizontal plates, vertical plates, clamping plates, and positioning plates. A fixed plate is fixedly connected between the upper parts of the two L-shaped sliding plates. Four fixed rods are fixedly connected at intervals to the bottom of the fixed plate. Horizontal plates are fixedly connected between the lower ends of two fixed rods located on the same side in the front-back direction. Multiple vertical plates are fixedly connected at intervals to the bottom of the two horizontal plates. Clamping plates are fixedly connected to the upper and lower sides of each vertical plate. Positioning plates are fixedly connected between the lower sides of two adjacent vertical plates on the front side and the corresponding two adjacent vertical plates on the rear side.

[0009] Furthermore, the drying assembly includes a mounting plate, air knives, connecting pipes, hoses, a hot air blower, and an air outlet pipe. The top of each of the two horizontal plates is fixedly connected to a mounting plate, and multiple air knives are rotatably connected between the two mounting plates at intervals. The bottom of the fixed plate is fixedly connected to a connecting pipe, and a hose is connected to the middle of the top of each air knife. The end of the hose away from the air knife is connected to the connecting pipe. A hot air blower is installed in the middle of the top of the fixed plate, and two air outlet pipes are symmetrically connected to the front of the hot air blower. The end of the air outlet pipe away from the hot air blower passes through the fixed plate and is connected to the connecting pipe.

[0010] Furthermore, it also includes mounting blocks, swing rods, electric push rods, short shafts, and extrusion blocks. Mounting blocks are symmetrically fixedly connected to the top of the front horizontal plate, and swing rods are slidably connected between two mounting blocks. An electric push rod is installed on the right side of the top of the front horizontal plate, and the telescopic rod end of the electric push rod is fixedly connected to the right end of the swing rod. A short shaft is fixedly connected to the front of each air knife. Multiple extrusion blocks are fixedly connected to the swing rod at intervals. Each extrusion block corresponds to a short shaft. Each extrusion block has a strip-shaped limiting hole, and each short shaft is located in the strip-shaped limiting hole opened on the adjacent extrusion block.

[0011] Furthermore, the length of the hose is greater than the vertical height between the air knife and the connecting pipe.

[0012] This invention has the following advantages: the clamping plate stably holds the circuit board and effectively separates it, creating a gap between the circuit boards. This allows the circuit boards to come into more full contact with the cleaning solution, thereby enhancing the cleaning effect. At the same time, the separated circuit boards also avoid damage caused by mutual friction during cleaning and lifting. By setting up components such as a hot air blower and air knife, the hot air blown by the hot air blown by the hot air blown by the hot air blown evenly into the gap between the circuit boards through the air knife. This not only quickly removes the moisture from the surface of the circuit boards, but also significantly improves the drying speed of the circuit boards. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Example: A board washing device for processing optical module circuit boards, such as... Figure 1-Figure 4As shown, it includes a base plate 1, a water tank 2, a valve pipe 21, an ultrasonic generator 22, a lifting assembly, a placement assembly, and a drying assembly. The top of the base plate 1 is fixedly connected to the water tank 2 for containing cleaning fluid. A valve pipe 21 for draining water is provided on the front side of the water tank 2. An ultrasonic generator 22 is embedded on the front side of the water tank 2. A lifting assembly is provided on the rear side of the water tank 2. A placement assembly for placing the circuit board to be cleaned is provided on the lifting assembly. A drying assembly for drying the circuit board is provided on the placement assembly. The lifting assembly is used to lift the placement assembly.

[0020] like Figure 1 and Figure 2 As shown, the lifting assembly includes a mounting base 31, an L-shaped sliding plate 32, a cylinder 33, and a crossbeam 34. Two mounting bases 31 are welded and fixed at intervals on the rear side of the water tank 2. An L-shaped sliding plate 32 is slidably mounted on each of the two mounting bases 31. A cylinder 33 is bolted to the middle of the rear side of the water tank 2. A crossbeam 34 is welded and fixed between the upper parts of the two L-shaped sliding plates 32. The piston rod end of the cylinder 33 is fixedly connected to the crossbeam 34.

[0021] like Figure 1 and Figure 3 As shown, the placement assembly includes a fixing plate 35, fixing rods 41, horizontal plates 42, vertical plates 43, clamping plates 44, and positioning plates 45. The fixing plate 35 is welded and fixed between the upper parts of the two L-shaped sliding plates 32. Four fixing rods 41 are fixed to the bottom of the fixing plate 35 at intervals by bolts. Horizontal plates 42 are welded and fixed between the lower ends of the two fixing rods 41 located on the same side in the front-back direction. Multiple vertical plates 43 are fixedly connected to the bottom of the two horizontal plates 42 at intervals. Clamping plates 44 are fixedly connected to the upper and lower sides of each vertical plate 43. The two clamping plates 44 located on different vertical plates 43 are mirror images of each other, and the clamping plates 44 are elastic plates. Positioning plates 45 are welded and fixedly connected between the lower sides of the two adjacent vertical plates 43 on the front side and the corresponding two adjacent vertical plates 43 on the rear side. When placing the circuit board to be cleaned and processed, the lower end of the circuit board can be kept in contact with the positioning plate 45 and then pushed backward between the clamping plates 44.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the drying assembly includes a mounting plate 51, an air knife 52, a connecting pipe 53, a flexible hose 54, a hot air blower 55, and an air outlet pipe 56. The tops of the two horizontal plates 42 are both welded and fixed with mounting plates 51. Multiple air knives 52 are rotatably connected between the two mounting plates 51 at intervals. The bottom of the fixed plate 35 is fixedly connected with a connecting pipe 53. A flexible hose 54 is connected to the middle of the top of each air knife 52. The end of the flexible hose 54 away from the air knife 52 is connected to the connecting pipe 53. The hot air blower 55 is bolted to the middle of the top of the fixed plate 35. Two air outlet pipes 56 are symmetrically connected to the front of the hot air blower 55. The end of the air outlet pipe 56 away from the hot air blower 55 passes through the fixed plate 35 and is connected to the connecting pipe 53. The hot air blower 55 is connected to the air knife 52 through the air outlet pipe 56, the connecting pipe 53, and the flexible hose 54.

[0023] First, the operator vertically inserts the circuit board to be cleaned between the upright plates 43. Two adjacent clamping plates 44 secure the circuit board to its top and bottom. Then, the cylinder 33 is activated, causing its piston rod to retract and move the L-shaped sliding plate 32 and all its upper components (including the placement components and the circuit board) downwards until the circuit board is completely immersed in the cleaning solution in the water tank 2. At this point, the operator activates the ultrasonic generator 22. The ultrasonic waves emitted by the generator work in conjunction with the cleaning solution to perform ultrasonic cleaning on the circuit board. Because the circuit board is separated between the upright plates 43, there are gaps between them, allowing for better contact between the circuit board and the cleaning solution, resulting in a better cleaning effect. This also prevents the circuit boards from rubbing against each other during the lifting and lowering process. This effectively prevents circuit board damage caused by friction. After cleaning, the staff restarts cylinder 33. The piston rod of cylinder 33 extends, driving the circuit board and all its components upward to separate the circuit board from the cleaning solution. Since the circuit board is placed vertically, it is easy to drain the cleaning solution from the circuit board. To speed up the drying of the circuit board, the staff can start the hot air blower 55. The hot air blower 55 blows dry hot air into the connecting pipe 53 through two air outlet pipes 56. Then, this hot air is evenly blown out from the air knife 52 through multiple hoses 54. Since the air knife 52 is set directly above the upright plate 43, that is, above the gap between the circuit boards, the hot air can blow through the gap between the circuit boards to dry the sides of the circuit board, thereby further accelerating the drying speed of the circuit board.

[0024] like Figure 4As shown, it also includes mounting blocks 61, swing rods 62, electric push rods 63, short shafts 64, and extrusion blocks 65. Mounting blocks 61 are symmetrically welded and fixed to the top of the front horizontal plate 42. Swing rods 62 are slidably connected between the two mounting blocks 61. Electric push rods 63 are installed on the right side of the top of the front horizontal plate 42 by bolts. The telescopic rod end of the electric push rod 63 is fixedly connected to the right end of the swing rod 62. Short shafts 64 are welded and fixed to the front of each air knife 52. Multiple extrusion blocks 65 are welded and fixed to the swing rods 62 at intervals. Each extrusion block 65 corresponds to a short shaft 64. Each extrusion block 65 has a strip-shaped limiting hole. Each short shaft 64 is located in the strip-shaped limiting hole on the adjacent extrusion block 65.

[0025] When using the hot air blower 55 to dry the circuit board, the operator can also start the electric push rod 63. The telescopic rod of the electric push rod 63 reciprocates by extending and retracting, pushing the swing rod 62 to swing left and right. The pressing block 65 follows the swing of the swing rod 62 and reciprocates left and right. It also pushes the short shaft 64 to make the air knife 52 swing. In this way, the hot air blown out from the air knife 52 can better contact the circuit board, further accelerating the drying speed of the circuit board.

[0026] like Figure 3 As shown, the length of the hose 54 is greater than the vertical height between the air knife 52 and the connecting pipe 53, so that the hose 54 does not restrict the swing of the air knife 52.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
