[0002] PCB board is a printed circuit board. It is a support for electronic components and a provider of circuit connections for electronic components. The main function of PCB board is to provide connections between electronic components. It is also a support for electronic components and a connection carrier for circuits. PCB board can be sprayed with glue through a dispensing machine. The glue can make the PCB board moisture-proof, insulated, and anti-aging. After the PCB board is sprayed with glue, an air-drying device is needed to quickly air-dry the glue on the PCB board, so that the PCB board can be quickly processed. The existing quick-drying device still has certain defects when used.

[0003] In the prior art, the quick-drying device usually uses a fan for air drying. The fan can accelerate the air flow speed, so that the glue on the PCB board can be quickly cured. Since there are certain dust particles in the indoor air, dust particles are present in the wind blown by the fan. The dust particles are easy to adhere to the surface of the PCB board, which will affect the use of the PCB board for a long time. Utility Model Content

[0004] The utility model aims to provide a PCB board glue spraying quick-drying device to solve the problem that the quick-drying devices currently on the market are difficult to filter dust particles as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PCB board glue spraying quick-drying device, comprising: a conveyor body, a conveyor belt, an air-drying box, a controller and an electric fan, the conveyor belt is installed on the inner side of the conveyor body, the air-drying box is installed on the top of the conveyor body, the controller is installed on the front of the air-drying box, and the electric fan is installed on the top of the air-drying box.

[0006] Preferably, a connecting frame is installed on the top of the air-drying box body by screws, the top of the connecting frame is installed with an induced draft fan body, a mounting block is welded to the inner wall of the connecting frame, a connecting rod is welded inside the mounting block, a docking block is movably connected to the outer side of the connecting rod, and a knob is connected through the inside of the docking block.

[0007] Preferably, a filter frame is provided between the mounting blocks, an exhaust port is provided through the bottom of the filter frame, a dust filter is placed inside the filter frame, and a connecting block is connected to the outside of the filter frame near the mounting block.

[0008] Preferably, a threaded structure is formed between the knob and the connecting block, and two groups of the mounting blocks are symmetrically arranged about the center of the connecting frame.

[0009] Preferably, a guide seat is welded on the top of the air-drying box body, and a fixing block is welded on the top of the air-drying box body away from the guide seat.

[0010] Preferably, the interior of the fixed block is connected to a screw rod via a bearing, the outer side of the screw rod is movably connected to a slider, and both sides of the slider are connected to pressure plates.

[0011] Preferably, a limiting protrusion is bonded to the bottom of the pressing plate, and a through hole is opened through the interior of the pressing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when the filter frame of the PCB board glue spraying and quick-drying device moves, the connecting block can be driven to move; when the connecting block moves to the inner wall surface of the connecting frame, the docking block can be pulled; when the docking block moves, it can be rotated by the connecting rod; when the knob is turned, the connecting block can be threaded through and threadedly fixed to the connecting frame; when the limiting protrusion is completely removed from the surface of the electric fan, the electric fan can be disassembled and maintained; and by quickly disassembling the electric fan, the maintenance efficiency of the electric fan can be improved.

[0013] 1. The quick-drying device can accelerate the curing time of the glue on the PCB board through the electric fan, but it is difficult to filter the dust particles in the air. When the filter frame moves, the connecting block can be driven to move. When the connecting block moves to the inner wall surface of the connecting frame, the docking block can be pulled. When the docking block moves, it can be rotated by the connecting rod. When the knob is turned, the thread can penetrate the connecting block and be threadedly fixed with the connecting frame. At this time, the filter frame can be installed inside the connecting frame. At this time, the induced draft fan body can be started. When the induced draft fan body is running, the air outside the connecting frame can be discharged into it. At the same time, the dust particles in the air can be filtered through the dust filter, so that the wind delivered by the electric fan to the conveyor belt does not contain dust particles, thereby preventing the surface of the PCB board from adhering to dust particles. By filtering the dust particles, the wind discharged by the electric fan is relatively clean and will not affect the PCB board.

[0014] 2. The two sets of electric fans on the quick-drying device are usually fixed to the top of the air-drying box body by screws, resulting in low disassembly and maintenance efficiency of the electric fans. When the screw rotates forward, it can drive the slider to slide upward. When the slider slides, it can drive the two sets of pressure plates to move. When the pressure plates move, they can slide through the guide seats. When the limit protrusions move, shape reset can occur. When the limit protrusions are completely removed from the surface of the electric fan, the electric fan can be disassembled and maintained. By quickly disassembling the electric fan, the maintenance efficiency of the electric fan can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 3It can be seen that the utility model provides a technical solution: a PCB board glue spraying quick-drying device, comprising: a conveyor body 1, a conveyor belt 2, an air-drying box body 3, a controller 4 and an electric fan 5, the conveyor belt 2 is installed on the inner side of the conveyor body 1, the air-drying box body 3 is installed on the top of the conveyor body 1, the controller 4 is installed on the front of the air-drying box body 3, the electric fan 5 is installed on the top of the air-drying box body 3, the top of the air-drying box body 3 is installed with a connecting frame 6 by screws, the top of the connecting frame 6 is installed with an induced draft fan body 7, the inner side of the connecting frame 6 is provided with a connecting frame 6, and the inner side of the connecting frame 6 is provided with a connecting frame 6. A mounting block 8 is welded to the wall, a connecting rod 9 is welded inside the mounting block 8, a docking block 10 is movably connected to the outside of the connecting rod 9, a knob 11 is connected to the inside of the docking block 10, a filter frame 12 is arranged between the mounting blocks 8, an exhaust port 13 is opened through the bottom of the filter frame 12, a dust filter 14 is placed inside the filter frame 12, a connecting block 15 is connected to the outside of the filter frame 12 near the mounting block 8, a threaded structure is formed between the knob 11 and the connecting block 15, and two groups of mounting blocks 8 are symmetrically arranged about the center of the connecting frame 6.

[0022] In specific implementation, the quick-drying device can accelerate the curing time of the glue on the PCB board through the electric fan 5, but it is difficult to filter the dust particles in the air. For this reason, the dust filter 14 can be placed inside the filter frame 12, and the filter frame 12 is pushed. When the filter frame 12 moves, the connecting block 15 can be driven to move. When the connecting block 15 moves to the inner wall surface of the connecting frame 6, the docking block 10 can be pulled. When the docking block 10 moves, it can be rotated by the connecting rod 9. When the docking block 10 rotates, it can drive the knob 11 to move. When one side of the docking block 10 is When it moves to the bottom surface of the connecting block 15, the knob 11 can be rotated. When the knob 11 is rotated, it can be threaded through the connecting block 15 and threadedly fixed with the connecting frame 6. At this time, the filter frame 12 can be installed inside the connecting frame 6. At this time, the induced draft fan body 7 can be started. When the induced draft fan body 7 is running, the air outside the connecting frame 6 can be discharged into the inside thereof. At the same time, the dust particles in the air can be filtered through the dust filter 14, so that the wind delivered by the electric fan 5 to the conveyor belt 2 does not contain dust particles, thereby preventing dust particles from adhering to the surface of the PCB board.

[0023] See also Figure 1 , Figure 2 and Figure 3 It can be seen that by filtering the dust particles, the air exhausted by the electric fan 5 is relatively clean and will not affect the PCB board.

[0024] See also Figure 2 and Figure 4It can be known that a guide seat 16 is welded to the top of the air-drying box body 3, and a fixed block 17 is welded to the top of the air-drying box body 3 away from the guide seat 16. The interior of the fixed block 17 is connected to a screw rod 18 through a bearing, and the outer side of the screw rod 18 is movably connected to a slider 19. Both sides of the slider 19 are connected to a pressure plate 20, and a limiting protrusion 21 is bonded to the bottom of the pressure plate 20. A through hole 22 is opened inside the pressure plate 20, and the limiting protrusion 21 is made of rubber.

[0025] In specific implementation, the two groups of electric fans 5 on the quick-drying device are usually fixed to the top of the air-drying box body 3 by screws, which results in low disassembly and maintenance efficiency of the electric fan 5. For this reason, the screw rod 18 can be rotated forward. When the screw rod 18 rotates forward, it can drive the slider 19 to slide upward. When the slider 19 slides, it can drive the two groups of pressure plates 20 to move. When the pressure plate 20 moves, it can slide through the guide seat 16. When the pressure plate 20 moves, it can drive the limiting protrusion 21 to move. The limiting protrusion 21 is made of rubber. When the limiting protrusion 21 moves, shape reset can be generated. When the limiting protrusion 21 is completely removed from the surface of the electric fan 5, the electric fan 5 can be disassembled and maintained.

[0026] See also Figure 2 and Figure 4 It can be seen that by quickly disassembling the electric fan 5, the maintenance efficiency of the electric fan 5 can be improved.

[0027] In summary, when the PCB board glue spraying and quick-drying device is used, when the PCB board is moved to the inside of the air-drying box body 3 through the conveyor belt 2 after being sprayed with glue, the electric fan 5 can be started by the controller 4. At this time, the electric fan 5 can air-dry the glue on the PCB board, so that the PCB board can be immediately processed. The PCB board glue spraying and quick-drying device is a prior art and will not be described in detail here. When the induced draft fan main body 7 is in operation, the air outside the connecting frame 6 can be discharged into the inside thereof, and at the same time, the dust particles in the air can be filtered through the dust filter 14, so that the electric fan 5 can be blown to the outside of the connecting frame 6. The air transported by the conveyor belt 2 does not contain dust particles, thereby preventing dust particles from adhering to the surface of the PCB board. By filtering the dust particles, the air exhausted by the electric fan 5 is relatively clean and will not affect the PCB board. When the limiting protrusion 21 moves, the shape can be reset. When the limiting protrusion 21 is completely removed from the surface of the electric fan 5, the electric fan 5 can be disassembled and maintained. By quickly disassembling the electric fan 5, the maintenance efficiency of the electric fan 5 can be improved.
