[0002] When processing the WIFI module, the printed circuit board (PCB) needs to be cut, and then the components (such as resistors, capacitors, diodes, etc.) need to be accurately mounted on the PCB surface. Then the chip and other components need to be soldered to the PCB. After debugging, the WIFI module can be coated with three-proof paint, and finally packaged to complete the WIFI module.

[0003] In the WIFI module processing flow, the PCB board after cutting will have pollutants such as dust and debris, which will affect the accuracy and reliability of the patch.

[0030] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0031] Embodiment The technical solution of the present invention will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. Please refer to Figures 1 to 6 A WIFI module processing device provided by this application. Please pay special attention to referring to Figure 1 and Figure 2 , which includes a workbench 1 and a conveyor belt 11 installed on the workbench 1; On the workbench 1, a main cleaning roller assembly 2, an auxiliary cleaning roller assembly 3, and a drying roller assembly 4 are rotatably connected in sequence from front to back. A driving mechanism 5 is arranged on the workbench 1 for driving the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3, and the drying roller assembly 4 to rotate synchronously; A water supply assembly 6 is arranged on the workbench 1 for quantitatively supplying water inside the main cleaning roller assembly 2; Two groups of symmetrically arranged positioning plate assemblies 7 are slidably connected to the workbench 1, and a moving mechanism 8 is arranged on the workbench 1 to drive the two positioning plate assemblies 7 to reciprocate.

[0032] Specifically, by starting the conveyor belt 11, the PCB board is placed on the conveyor belt 11 for transmission. The moving mechanism 8 drives the two positioning plate assemblies 7 to reciprocate, thereby being able to position each PCB board during transmission. The driving mechanism 5 drives the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3, and the drying roller assembly 4 to rotate synchronously, so that the PCB board undergoes three steps of cleaning, wiping, and drying in sequence, thus completing the cleaning operation. Through the water supply assembly 6, water can be quantitatively supplied inside the main cleaning roller assembly 2, so as to keep the main cleaning roller assembly 2 always in a wet state.

[0033] Please pay special attention to referring to Figure 2 and Figure 3, the driving mechanism 5 includes a first gear 51, an internal tooth belt 52, a bracket 53 and a motor 54; First gears 51 are connected to the same-side shafts of the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3 and the drying roller assembly 4. The outer walls of the three first gears 51 are jointly engaged with an internal tooth belt 52. A bracket 53 is installed on the workbench 1, and a motor 54 is installed on the bracket 53. The output end of the motor 54 is sleeved on the side shaft of the main cleaning roller assembly 2.

[0034] Specifically, the main cleaning roller assembly 2 is driven to rotate by the motor 54, causing the first gear 51 on the side shaft to rotate. Under the driving action of the internal tooth belt 52, the other two first gears 51 are driven to rotate, and then the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3 and the drying roller assembly 4 rotate synchronously.

[0035] Please refer specifically to Figure 1 and Figure 4 , the main cleaning roller assembly 2 includes a first hollow roller 21, a first water outlet 22 and a first cleaning cotton 23; A first hollow roller 21 is rotatably connected to the workbench 1. A plurality of first water outlets 22 are equidistantly arranged on the first hollow roller 21, and a first cleaning cotton 23 is coated on the outer wall of the first hollow roller 21.

[0036] Specifically, when the first hollow roller 21 rotates, the water inside the first hollow roller 21 flows out through the first water outlet 22, and the water adheres to the first cleaning cotton 23, thereby wetting the first cleaning cotton 23. When the PCB board is transported on the conveyor belt 11, the wet first cleaning cotton 23 will adhere to the PCB board, so that the dust and debris on the PCB board can be removed.

[0037] Please refer specifically to Figure 1 and Figure 4 , the auxiliary cleaning roller assembly 3 includes a second hollow roller 31, a first air outlet 32 and a second cleaning cotton 33; A second hollow roller 31 is rotatably connected to the workbench 1. A plurality of first air outlets 32 are equidistantly arranged on the second hollow roller 31, and a second cleaning cotton 33 is coated on the outer wall of the second hollow roller 31.

[0038] Please refer specifically to Figure 3 and Figure 4 , the drying roller assembly 4 includes a third hollow roller 41, a second air outlet 42, a hot air blower 43, an air delivery pipe 44 and a connecting rod 45; A third hollow roller 41 is rotatably connected to the workbench 1. A plurality of second air outlets 42 are equidistantly arranged on the third hollow roller 41. A hot air blower 43 is installed on the workbench 1. The air outlet of the hot air blower 43 is rotatably connected to one side shaft end of the third hollow roller 41. The other side shaft end of the third hollow roller 41 is rotatably connected to an air delivery pipe 44. The other end of the air delivery pipe 44 is rotatably connected to the end of the second hollow roller 31. Both ends of the air delivery pipe 44 are communicated with the third hollow roller 41 and the second hollow roller 31 respectively. A plurality of connecting rods 45 are equidistantly connected to the bottom end of the air delivery pipe 44. Each connecting rod 45 is connected to the workbench 1.

[0039] Specifically, the hot air blower 43 supplies air to the inside of the third hollow roller 41, so that the hot air is ejected through the second air outlets 42. Part of the hot air will enter the inside of the second hollow roller 31 through the air delivery pipe 44, thereby playing a role in preheating the second hollow roller 31. Part of the hot air will be ejected along the first air outlet 32. When the PCB board is cleaned by the wet first cleaning cotton 23, the PCB board will contact the outer wall of the second cleaning cotton 33, so that the second cleaning cotton 33 wipes the water stains attached to the PCB board. Since the second hollow roller 31 is in a preheated state, it will accelerate the evaporation of the water on the second cleaning cotton 33. At the same time, the first air outlet 32 on the second hollow roller 31 will eject part of the hot air to accelerate the removal of the water stains on the PCB board. When the PCB board moves below the third hollow roller 41 after being wiped, the third hollow roller 41 ejects a large amount of hot air through the second air outlets 42, thereby playing a role in drying the PCB board, and thus avoiding water stains remaining on the PCB board.

[0040] Please refer specifically to Figure 3 and Figure 5 , the water supply assembly 6 includes a water inlet tank 61, a water inlet 62, a second water outlet 63, a one-way valve 64, a water outlet pipe 65, a pressing plate 66, a pressing rod 67, a first spring 68, a first cam 69; The water inlet tank 61 is connected to the workbench 1. The left and right sides of the bottom end of the water inlet tank 61 are respectively provided with a water inlet 62 and a second water outlet 63. One-way valves 64 are installed on the inner walls of the water inlet 62 and the second water outlet 63. The end of the water inlet 62 is externally connected to a water supply tank. The end of the second water outlet 63 is connected to a water outlet pipe 65. The top end of the water outlet pipe 65 is rotatably connected to and communicated with one end of the first hollow roller 21 far from the motor 54. A pressing plate 66 is slidably connected to the inside of the water inlet tank 61. The top end of the pressing plate 66 is connected to a pressing rod 67. The outer wall of the pressing rod 67 is connected to a first spring 68. The other end of the first spring 68 is connected to the top end of the water inlet tank 61. One end side shaft of the second hollow roller 31 far from the first gear 51 is connected to a first cam 69. The outer wall of the first cam 69 is attached to the top end of the pressing rod 67.

[0041] Specifically, when the second hollow roller 31 rotates, it drives the first cam 69 to rotate, causing the first cam 69 to squeeze the pressure rod 67. The pressure rod 67 drives the pressing plate 66 to move downward inside the water inlet tank 61. Then, the water inside the water inlet tank 61 enters the inside of the water outlet pipe 65 through the second water outlet 63. The water flows along the water outlet pipe 65 into the inside of the first hollow roller 21, thereby replenishing water inside the first hollow roller 21. Under the action of the first spring 68, the pressure rod 67 will move upward, and then drive the pressing plate 66 to move upward synchronously. At this time, since the inside of the water inlet tank 61 is in a negative pressure state, when the pressing plate 66 moves upward, it will draw the water inside the water tank externally connected to the water inlet 62, thereby being able to maintain the water storage inside the water inlet tank 61 and simultaneously realizing the function of quantitatively supplying water to the inside of the first hollow roller 21.

[0042] Please refer particularly to Figure 1 and Figure 2 , the positioning plate assembly 7 includes a positioning frame 71, rollers 72 and sliding rods 73; Two positioning frames 71 are symmetrically attached to the top of the conveyor belt 11. A plurality of rollers 72 are equidistantly rotatably connected to the inner wall of each positioning frame 71. Two sliding rods 73 are connected to the outer wall of each positioning frame 71, and each sliding rod 73 is slidably connected to the workbench 1.

[0043] Specifically, by providing the rollers 72, the wear on the side wall of the PCB board can be reduced, and at the same time, it can still play a positioning role when the positioning plate assembly 7 approaches the PCB board. By providing the sliding rods 73, the positioning plate assembly 7 can be kept stable during lateral movement and will not produce an offset phenomenon.

[0044] Please refer particularly to Figure 1 and Figure 2 , the moving mechanism 8 includes a fixed plate 81, a vertical shaft 82, a first connecting rod 83, a second connecting rod 84, a second gear 85, a rack 86, a limiting block 87 and a power assembly 88; A fixed plate 81 is connected to the workbench 1. A vertical shaft 82 is rotatably connected to the fixed plate 81. The bottom end of the vertical shaft 82 is connected to a first connecting rod 83. Both ends of the first connecting rod 83 are rotatably connected to a second connecting rod 84. The ends of the two second connecting rods 84 far from the first connecting rod 83 are rotatably connected to the top of the positioning frame 71. The upper end of the vertical shaft 82 is connected to a second gear 85. The outer wall of the second gear 85 meshes with a rack 86. The rack 86 is slidably connected to the workbench 1. Limiting blocks 87 are connected to both ends of the rack 86. A power assembly 88 is provided on the outer wall of the workbench 1 to drive the rack 86 to reciprocate.

[0045] Specifically, the power assembly 88 drives the rack 86 to reciprocate, thereby causing the vertical shaft 82 connected inside the second gear 85 to rotate, driving the first connecting rod 83 to rotate, and then driving the two second connecting rods 84 to rotate. When the second connecting rods 84 rotate, they drive the positioning plate assembly 7 to reciprocate on the conveyor belt 11, so that the positioning plate assembly 7 can intermittently position and clamp the PCB board moving on the conveyor belt 11.

[0046] Please refer particularly to Figure 1 and Figure 6 , the power assembly 88 includes side plates 881, a rotating rod 882, a first bevel gear 883, a second bevel gear 884, a second cam 885, and a second spring 886; The side plates 881 are connected to the workbench 1, and the rotating rod 882 is rotatably connected to the side plates 881. One end of the rotating rod 882 is connected to the first bevel gear 883. The outer wall of the first bevel gear 883 meshes with the second bevel gear 884. The second bevel gear 884 is connected to the side shaft of the first hollow roller 21 near the motor 54. The other end of the rotating rod 882 is connected to the second cam 885. The outer wall of the second cam 885 is attached to the outer wall of any one of the limit blocks 87. The outer wall of the other limit block 87 is connected to the second spring 886, and the other end of the second spring 886 is connected to the outer wall of the workbench 1.

[0047] Specifically, the motor 54 drives the first hollow roller 21 to rotate, causing the second bevel gear 884 on the side shaft of the first hollow roller 21 to drive the first bevel gear 883 to rotate. Then, the first bevel gear 883 drives the rotating rod 882 to rotate, and the rotating rod 882 drives the second cam 885 to rotate. When the second cam 885 rotates, it continuously presses the limit block 87, so that the limit block 87 drives the rack 86 to move on the workbench 1. Under the action of the second spring 886, the limit block 87 can quickly return to its original position. Under the action of the second cam 885 and the second spring 886, the reciprocating movement of the rack 86 can be realized.

[0048] On the other hand, the embodiment of the present application also provides a processing method for a WIFI module processing device according to the above, including the following steps: S1: Start the conveyor belt 11 and place the PCB board to be cleaned on the conveyor belt 11 for transmission; S2: Drive the two positioning plate assemblies 7 to reciprocate on the conveyor belt 11 through the moving mechanism 8, so that the two positioning plate assemblies 7 are intermittently attached to the side walls of the PCB board; S3: Start the water supply assembly 6 to supply a fixed amount of water to the main cleaning roller assembly 2; S4: Start the hot air blower 43 to make the drying roller assembly 4 spray hot air; S5: Receive the surplus hot air of the drying roller assembly 4 through the air delivery pipe 44 to preheat the auxiliary cleaning roller assembly 3; S6: Drive the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3, and the drying roller assembly 4 to rotate synchronously through the driving mechanism 5, so that the PCB board undergoes three steps of cleaning, wiping, and drying in sequence, thereby completing the cleaning operation.

[0049] Working principle: Drive the first hollow roller 21 to rotate through the motor 54, so that the second bevel gear 884 on the side shaft of the first hollow roller 21 drives the first bevel gear 883 to rotate. Furthermore, the first bevel gear 883 drives the rotating rod 882 to rotate, and the rotating rod 882 drives the second cam 885 to rotate. When the second cam 885 rotates, it continuously presses the limit block 87, so that the limit block 87 drives the rack 86 to move on the workbench 1. Under the action of the second spring 886, the limit block 87 can quickly return to its original position. Under the action of the second cam 885 and the second spring 886, the reciprocating movement of the rack 86 can be realized. Through the reciprocating movement of the rack 86, the vertical shaft 82 connected inside the second gear 85 is driven to rotate, driving the first connecting rod 83 to rotate, and further driving the two second connecting rods 84 to rotate. When the second connecting rod 84 rotates, it drives the positioning plate assembly 7 to reciprocate on the conveyor belt 11, so that the positioning plate assembly 7 can intermittently position and clamp the PCB board moving on the conveyor belt 11; Drive the main cleaning roller assembly 2 to rotate through the motor 54, so that the main cleaning roller assembly 2 drives the first gear 51 on the side shaft to rotate. Under the transmission action of the internal tooth belt 52, the other two first gears 51 are driven to rotate, and further the main cleaning roller assembly 2, the auxiliary cleaning roller assembly 3, and the drying roller assembly 4 rotate synchronously; Through the rotation of the first hollow roller 21, the water inside the first hollow roller 21 flows out through the first water outlet 22, and the water adheres to the first cleaning cotton 23, thereby wetting the first cleaning cotton 23. When the PCB board is transported on the conveyor belt 11, the wet first cleaning cotton 23 will stick to the PCB board, so that the dust and debris on the PCB board can be removed. Send air into the third hollow roller 41 through the hot air blower 43, so that the hot air is ejected through the second air outlet 42. Part of the hot air will enter the second hollow roller 31 through the air delivery pipe 44, thereby playing a role in preheating the second hollow roller 31. Part of the hot air will be ejected along the first air outlet 32. When the PCB board passes through the wet first cleaning cotton 23 for cleaning, the PCB board will contact the outer wall of the second cleaning cotton 33, so that the second cleaning cotton 33 wipes the water stains attached to the PCB board. Since the second hollow roller 31 is in a preheated state, the evaporation of the water on the second cleaning cotton 33 will be accelerated. At the same time, part of the hot air will be ejected from the first air outlet 32 on the second hollow roller 31, accelerating the removal of the water stains on the PCB board. When the PCB board moves to the lower part of the third hollow roller 41 after being wiped, the third hollow roller 41 ejects a large amount of hot air through the second air outlet 42, thereby playing a role in drying the PCB board, and further avoiding water stains remaining on the PCB board; When the second hollow roller 31 rotates, it drives the first cam 69 to rotate, causing the first cam 69 to press the pressure rod 67, and the pressure rod 67 drives the pressing plate 66 to move downward inside the water inlet tank 61. Then, the water inside the water inlet tank 61 enters the inside of the water outlet pipe 65 through the second water outlet 63. The water flows along the water outlet pipe 65 into the inside of the first hollow roller 21, thereby replenishing the water inside the first hollow roller 21. Under the action of the first spring 68, the pressure rod 67 will move upward, and then drive the pressing plate 66 to move upward synchronously. At this time, since the inside of the water inlet tank 61 is in a negative pressure state, when the pressing plate 66 moves upward, it will extract the water from the water tank connected to the water inlet 62, thereby being able to maintain the water storage inside the water inlet tank 61 and simultaneously realizing the function of quantitatively supplying water to the inside of the first hollow roller 21.
