Description

Technical Field

[0001] This utility model relates to the technical field of circuit board cleaning equipment, specifically, to a circuit board surface cleaning device for copper plating of circuit boards. Background Technology

[0002] In the circuit board manufacturing process, the cleanliness of the circuit board surface plays a crucial role in the quality of subsequent copper plating processes. If dust, impurities, or other contaminants are present on the circuit board surface, it can lead to uneven copper plating, poor adhesion, or even incomplete plating, severely affecting the performance and lifespan of the circuit board.

[0003] Currently, the common methods for cleaning circuit board surfaces mainly include the following:

[0004] Firstly, manual cleaning. Operators use simple tools such as brushes and air guns to clean the surface of the circuit boards. This method is not only inefficient and difficult to meet the needs of large-scale production, but the cleaning effect also largely depends on the operator's experience and diligence, easily resulting in incomplete cleaning. For example, on some circuit boards with complex structures, it is difficult for manual cleaning to reach certain corners and crevices, leading to contaminant residue.

[0005] Secondly, there are traditional automated cleaning equipment. Some automated equipment only uses a single cleaning method, such as simple air blowing or simple mechanical brushing. Simple air blowing may not be effective in removing some sticky contaminants; simple mechanical brushing may scratch the circuit board surface due to improper force control, affecting the electrical performance of the circuit board. Moreover, most of these devices do not have the function of flipping the circuit board for cleaning, and can only clean one side of the circuit board. For circuit boards that require double-sided copper plating, an additional flipping operation is required, increasing the process flow and time costs.

[0006] In summary, existing circuit board surface cleaning devices have varying degrees of deficiencies in terms of cleaning efficiency and cleaning effect. Therefore, a device capable of cleaning the surface of circuit boards was designed. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a circuit board surface cleaning device for copper plating of circuit boards. The device is equipped with a first cleaning component and a second cleaning component. The first cleaning component is connected to an inclined discharge channel and works with an auxiliary flipping component to achieve double-sided cleaning of the circuit board. The first fan and the first electrostatic dust removal rod in the first cleaning component can blow air and remove dust from one side of the circuit board. After cleaning, the circuit board slides down through the discharge channel to the auxiliary flipping component, and after flipping, it enters the second cleaning component for further cleaning, ensuring that both sides of the circuit board are effectively cleaned.

[0008] A circuit board surface cleaning device for copper plating of circuit boards includes a first cleaning component and a second cleaning component. The first cleaning component is connected to a discharge channel, which is inclined. Both the first and second cleaning components are mounted on a base. An auxiliary flipping component is fixedly mounted on the base, and the auxiliary flipping component corresponds to the lower end of the discharge channel.

[0009] The auxiliary flipping assembly includes a fixed column that fixes the base. An electric push rod is fixed to one side of the fixed column. The telescopic rod of the electric push rod is fixedly connected to a push block. The upper side of the push block is an inclined surface. The push block corresponds to the lower end of the discharge channel, and the lower end of the discharge channel is an arc-shaped surface.

[0010] As a further limitation of this technical solution, the first cleaning component includes a first conveyor belt assembly, which is mounted on a first conveyor belt support. First support legs are fixedly installed at the four corners of the first conveyor belt support, and these legs are fixed to a base. A first fan mounting bracket is fixedly connected to one side of the first conveyor belt support, and a first fan is fixedly mounted on the first fan mounting bracket. The first fan is located on the upper side of one end of the first conveyor belt assembly. A first electrostatic dust removal rod is located on the upper side of the other end of the first conveyor belt assembly. The first electrostatic dust removal rod is fixedly connected to a first bracket, which fixes the first conveyor belt support. The first electrostatic dust removal rod is located at one end of the discharge channel, and the lower arc-shaped surface of the discharge channel corresponds to the feed end of the second cleaning component. The feed end of the second cleaning component corresponds to the auxiliary flipping component.

[0011] As a further limitation of this technical solution, the second cleaning component includes a second conveyor belt assembly, which is mounted on a second conveyor belt support. Second support legs are fixedly installed at the four corners of the second conveyor belt support, and the second support legs are fixed to the base. A second fan mounting bracket is fixedly installed at the upper end of one side of the second conveyor belt support, and the second fan mounting bracket secures the second fan. A second bracket is fixedly installed at the upper end of the other side of the second conveyor belt support, and the second bracket secures the second electrostatic dust removal rod, which corresponds to the discharge port of the second conveyor belt assembly.

[0012] As a further limitation of this technical solution, the first support leg is higher than the second support leg, and the first conveyor belt assembly is disposed on the upper side of the second conveyor belt assembly;

[0013] As a further limitation of this technical solution, a container is provided on the base, and the container corresponds to the discharge port of the second conveyor belt assembly.

[0014] As a further limitation of this technical solution, both the first conveyor belt assembly and the second conveyor belt assembly include a motor, a conveyor belt, a conveyor belt pulley, and a drive shaft. The two ends of the first conveyor belt support and the second conveyor belt support are respectively bearing connected to the drive shaft.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are:

[0016] This device is equipped with a first cleaning component and a second cleaning component. The first cleaning component is connected to an inclined discharge channel and, together with an auxiliary flipping component, can achieve double-sided cleaning of the circuit board. The first fan and the first electrostatic dust removal rod in the first cleaning component can blow air and remove electrostatic dust on one side of the circuit board. After cleaning, the circuit board slides down through the discharge channel to the auxiliary flipping component, flips over, and enters the second cleaning component for further cleaning, ensuring that both sides of the circuit board can be effectively cleaned.

[0017] A container is installed below the discharge port of the second conveyor belt assembly to collect circuit boards;

[0018] The auxiliary flipping component uses an electric push rod to push a push block with an inclined surface. Combined with the arc-shaped surface at the lower end of the discharge channel, this design exerts a gentler force on the circuit board during the flipping process, effectively preventing damage to the circuit board during the flipping operation.

[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0025] A circuit board surface cleaning device for copper plating of circuit boards includes a first cleaning component and a second cleaning component. The first cleaning component is connected to a discharge channel 5, which is inclined. Both the first cleaning component and the second cleaning component are mounted on a base 9. An auxiliary flipping component is fixedly mounted on the base 9, and the auxiliary flipping component corresponds to the lower end of the discharge channel 5.

[0026] The auxiliary flipping assembly includes a fixed column 8, which fixes the base 9. An electric push rod 7 is fixed to one side of the fixed column 8. The telescopic rod of the electric push rod 7 is fixedly connected to a push block 6. The upper side of the push block 6 is an inclined surface. The push block 6 corresponds to the lower end of the discharge channel 5. The lower end of the discharge channel 5 is an arc-shaped surface 14.

[0027] In this embodiment, the circuit board at the lower end of the discharge channel 5 slides down to the auxiliary flipping assembly. At this time, the electric push rod 7 is activated, and the telescopic rod extends to push the push block 6. Since the upper side of the push block 6 is an inclined surface and the lower end of the discharge channel 5 is an arc surface 14, the circuit board is flipped along the arc surface 14 and the inclined surface under the push of the push block 6. The flipped circuit board is pushed to the feeding end of the second cleaning assembly.

[0028] The first cleaning component includes a first conveyor belt assembly 1, which is mounted on a first conveyor belt support 4. First support legs 10 are fixedly installed at the four corners of the first conveyor belt support 4 and are fixed to a base 9. A first fan mounting bracket 12 is fixedly connected to one side of the first conveyor belt support 4. A first fan 13 is fixedly installed on the first fan mounting bracket 12. The first fan 13 is located on the upper side of one end of the first conveyor belt assembly 1. A first electrostatic dust removal rod 2 is installed on the upper side of the other end of the first conveyor belt assembly 1. The first electrostatic dust removal rod 2 is fixedly connected to a first bracket 3, which fixes the first conveyor belt support 4. The first electrostatic dust removal rod 2 is located at one end of the discharge channel 5. The lower arc-shaped surface 14 of the discharge channel 5 corresponds to the feed end of the second cleaning component, which corresponds to the auxiliary flipping component.

[0029] In this embodiment, after the device is started, the circuit board is placed on the first conveyor belt assembly 1. The motor 101 drives the transmission shaft 104 to rotate, which in turn causes the conveyor belt pulley 103 to rotate, and the circuit board moves on the first conveyor belt assembly 1 via the conveyor belt 102. When the circuit board moves below the first fan 13, the air blown by the first fan 13 blows up some of the dust and impurities on the surface of the circuit board. As the circuit board continues to move, it reaches the position of the first electrostatic dust removal rod 2. The first electrostatic dust removal rod 2 generates static electricity, adsorbing the remaining dust and fine particles, thus initially completing the cleaning of one side of the circuit board. The cleaned circuit board slides down the inclined discharge channel 5.

[0030] The second cleaning component includes a second conveyor belt (102) component, which is mounted on a second conveyor belt support 19. The four corners of the second conveyor belt support 19 are respectively fixed with second support legs 11, which are fixed on the base 9. A second fan mounting bracket 16 is fixedly mounted on the upper end of one side of the second conveyor belt support 19, which fixes the second fan 15. A second bracket 18 is fixedly mounted on the upper side of the other side of the second conveyor belt support 19, which fixes the second electrostatic dust removal rod 17. The second electrostatic dust removal rod 17 corresponds to the discharge port of the second conveyor belt (102) component.

[0031] In this embodiment, the flipped circuit board enters the second conveyor belt (102) assembly. Similar to the first conveyor belt assembly 1, the motor 101 drives the circuit board to move on the second conveyor belt (102) assembly. When the circuit board passes under the second fan 15, the second fan 15 further blows away any dust that may have been stirred up during the flipping process. Then, the circuit board reaches the position of the second electrostatic dust removal rod 17, which again adsorbs residual impurities, completing the cleaning of the other side of the circuit board. Finally, the cleaned circuit board is discharged from the outlet of the second conveyor belt (102) assembly and falls into the container 20 below.

[0032] The first support leg 10 is higher than the second support leg 11, and the first conveyor belt assembly 1 is disposed on the upper side of the second conveyor belt (102) assembly;

[0033] A container 20 is provided on the base 9, and the container 20 corresponds to the discharge port of the second conveyor belt (102) assembly.

[0034] The first conveyor belt assembly 1 and the second conveyor belt (102) assembly both include a motor 101, a conveyor belt 102, a conveyor belt pulley 103 and a drive shaft 104. The two ends of the first conveyor belt support 4 and the second conveyor belt support 19 are respectively bearing connected to the drive shaft 104. The two ends of the drive shaft 104 are respectively fixedly connected to the conveyor belt pulley 103. The conveyor belt pulley 103 is driven by the conveyor belt 102. The first conveyor belt support 4 and the second conveyor belt support 19 are respectively fixedly connected to the motor 101. The motor 101 is fixedly connected to the corresponding drive shaft 104.

[0035] In this embodiment, the first conveyor belt assembly 1 and the second conveyor belt (102) assembly have opposite conveying directions.

[0036] The working process of this utility model is as follows:

[0037] Place the circuit board to be cleaned at the feed end of the first conveyor belt assembly 1. Ensure the circuit board is placed stably to avoid tilting or getting stuck. Start the first cleaning assembly and the second cleaning assembly. The first cleaning assembly blows air and electrostatically removes dust from one side of the circuit board. After cleaning, the circuit board slides down the discharge channel 5 to the auxiliary flipping assembly for flipping. Then, it enters the second cleaning assembly to clean the other side. The cleaned circuit board falls from the discharge port of the second conveyor belt (102) assembly into the container 20. The operator can periodically take out the cleaned circuit board from the container 20 for subsequent copper plating and other processes.

[0038] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
