Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a device for dust removal and dehumidification of sheet metal. Background Technology

[0002] Circuit board assembly and processing, its core components are circuit boards and components. In the process of manufacturing the board material, the selection of materials is crucial, especially the material selection of PCB boards, which varies from product to product. Specifically, there are many types of PCB materials, mainly including 94HB, 94V0, FR-4, CEM-1, aluminum substrate and flexible board. FR-4 board material has become the most common choice due to its excellent performance and wide range of applications.

[0003] A search revealed Chinese Patent Publication No. CN221453452U, which discloses a dust removal and dehumidification device for sheet metal, belonging to the field of sheet metal processing technology. It addresses the problems of low dust removal and dehumidification efficiency and difficulty in cleaning up dust debris. The device includes a workbench with a placement box fixedly connected to its top surface. A pad is fixedly connected to the inner wall of the placement box's bottom surface, and a rotating motor is fixedly connected to the top surface of the pad. A drive shaft is fixedly connected to the output end of the rotating motor, and a rotating head is fixedly connected to the top of the drive shaft. This invention uses two sets of clamping rods to fix the sheet metal within the clamps. The two sets of clamping rods are used alternately, improving the dust removal and dehumidification efficiency of the sheet metal. A collection bucket is included, allowing dust debris to fall into the collection bucket through a drain hole. Clean water is injected into the collection bucket through a water inlet pipe, mixing the debris with the water and discharging it through an outlet pipe. This effectively avoids the problems of low dust removal and dehumidification efficiency and difficulty in cleaning up dust debris. Spray cleaning is suitable for cleaning large areas of board surfaces, but it is not effective at cleaning impurities inside crevices. Dry ice cleaning, as a physical method, can avoid chemical residues, but its strong impact can damage precision electronic components. Therefore, a device for dust removal and dehumidification of board materials is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for dust removal and dehumidification of sheet metal, aiming to improve the problem that the large impact force during cleaning in the prior art leads to damage to precision electronic components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for dust removal and dehumidification of sheet metal, comprising a cleaning box, a shelf fixedly connected to the top inner side of the cleaning box, a heater fixedly connected to the top of the cleaning box, one end of the heater penetrating the top of the cleaning box and fixedly connected to a heating pipe, connecting pipe 1 connecting to both the front and rear sides of the cleaning box, a fan connecting to adjacent ends of the two connecting pipe 1, the other ends of the two fans penetrating the front and rear sides of the cleaning box and connected to connecting pipe 2, multiple nozzles connecting to adjacent ends of the two connecting pipe 2, an air inlet connecting to the top of the cleaning box, and a clamping mechanism provided inside the cleaning box.

[0006] The above technical solution achieves effective removal of dust particles from the board surface by adjusting the fan pressure difference. The dust falls into the bottom of the cleaning box and is absorbed by the clean water at the bottom. Then, the drying mode is switched on, the heater is turned on and the appropriate temperature is preset. At the same time, the fan sends warm air to the board to accelerate the evaporation rate. By adopting non-contact cleaning technology, the potential damage caused by physical friction is greatly reduced.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes multiple mounting plates. Adjacent sides of each mounting plate are fixedly connected to the left and right sides of the cleaning box. Adjacent mounting plates are rotatably connected to rollers. A servo motor is fixedly connected to the rear side of the right mounting plate. The output end of the servo motor passes through the rear side of the mounting plate and is fixedly connected to the rear end of the roller. The outer walls of two rollers are connected by connecting strips. Multiple mounting blocks are fixedly connected to the outer walls of two connecting strips. Toothed plates are fixedly connected to the front and rear sides of the interior of the cleaning box. Gears are rotatably connected to adjacent sides of each mounting block. The outer walls of multiple gears are meshed with the top of the toothed plates. A fixing frame is fixedly connected to adjacent gears. Sliding grooves are provided on the left and right sides of the fixing frame. Clamping plates are slidably connected inside the two sliding grooves. Adjusting bolts are threadedly connected to the front and rear sides of the fixing frame. Adjacent ends of two adjusting bolts pass through the front and rear sides of the fixing frame and are threadedly connected to the inner wall of the clamping plate.

[0009] The above technical solution involves rotating the adjusting bolts on both sides of the fixed frame to drive the clamping plates to move back and forth, thereby clamping the plate. The servo motor drives the roller to move the mounting block on the connecting belt. During the movement of the fixed frame, the meshing of gears and toothed plates causes the fixed frame to rotate the plate, achieving a more comprehensive cleaning process.

[0010] As a further description of the above technical solution:

[0011] A filter plate is fixedly connected to the top of the air inlet, and multiple fasteners are installed on the front and rear sides of the air inlet.

[0012] The above technical solution involves sealing the air inlet with a filter plate to prevent dust from adhering to the intake air.

[0013] As a further description of the above technical solution:

[0014] Each of the cleaning boxes has multiple observation windows fixedly connected to its front side, and each of the observation windows has bolts threadedly connected to its front side.

[0015] The above technical solution allows for real-time monitoring of the internal cleaning process through an observation window, enabling staff to operate on the internal conditions more quickly.

[0016] As a further description of the above technical solution:

[0017] The bottom of the cleaning box is fixedly connected to a support frame, and the bottom end of the support frame is fixedly connected to multiple rubber pads.

[0018] The above technical solution improves the stability and robustness of the entire device by supporting the cleaning box with a support frame.

[0020] A collection box is slidably connected to the top right side of the support frame, and the collection box has fastening slots on both the left and right sides.

[0021] The above technical solution involves using collection boxes to collect the cleaned boards, facilitating subsequent handling.

[0022] As a further description of the above technical solution:

[0023] A control box is fixedly connected to the front side of the support frame, and the control box is electrically connected to the servo motor, the heater and the fan respectively.

[0024] The above technical solution allows for convenient and simple operation and control of the equipment throughout the entire device via a control box.

[0025] As a further description of the above technical solution:

[0026] A placement rack is fixedly connected to the front side of the support frame, and the top of the placement rack is fixedly connected to the bottom of the control box.

[0027] The above technical solution involves reinforcing the control box with a mounting frame to ensure its stability.

[0038] 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.

[0039] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a device for dust removal and dehumidification of sheet materials, comprising a cleaning box 1, a shelf 3 fixedly connected to the top inner side of the cleaning box 1, a heater 4 fixedly connected to the top of the cleaning box 1, one end of the heater 4 penetrating the top of the cleaning box 1 and fixedly connected to a heating pipe 5, the heating pipe 5 being positioned between the shelf 3 and the cleaning box 1, and the temperature being controlled by the heater 4 to achieve more suitable drying treatment of the sheet materials; connecting pipes 6 are connected to both the front and rear sides of the cleaning box 1, and adjacent ends of the two connecting pipes 6 are connected to fans 7, the other ends of the two fans 7 penetrating the front and rear sides of the cleaning box 1 and connected to connecting pipes 8, and adjacent ends of the two connecting pipes 8 are connected to The cleaning box 1 has multiple nozzles 9, which are located at the bottom. By activating the fan 7, external air is drawn in and sprayed onto the surface of the board, achieving fine removal of dust from the board surface. By activating the heater 4, the temperature inside the shelf 3 is increased, and the fan 7 works in conjunction with the nozzles 9 to dry the surface of the board. The top of the cleaning box 1 is connected to an air inlet 10. The cleaning box 1 is equipped with a clamping mechanism 2. A filter plate 11 is fixedly connected to the top of the air inlet 10. Multiple fasteners 12 are installed on the front and rear sides of the air inlet 10. By installing the filter plate 11 on the top of the air inlet 10, the external air is filtered to prevent dust from entering.

[0040] Specifically, a shelf 3 is firmly fixed to the top inner side of the cleaning box 1. The shelf 3 acts as a separator, clearly dividing the heating area from the board processing area, ensuring that the heating process does not directly cause thermal stress to the board. A heater 4 is securely installed on the top of the cleaning box 1, with one end passing through the top and tightly connected to a heating pipe 5. The heating pipe 5 is cleverly arranged between the shelf 3 and the bottom of the cleaning box 1, forming a uniform heating area. By precisely controlling the power and operating time of the heater 4, the internal temperature of the cleaning box 1 can be precisely adjusted, providing a more suitable and uniform drying environment for the board. This temperature control mechanism helps to quickly and effectively remove moisture from the board while avoiding potential damage caused by overheating. Connecting pipes 6 are respectively installed on the front and rear sides of the cleaning box 1, tightly connected to the fan 7, forming a key part of the air circulation system. When the fan 7 starts, it draws in external air through connecting pipe 6, pressurizes it, and then delivers it to the bottom of the cleaning box 1 through connecting pipe 8. At the end of connecting pipe 8, multiple precisely designed nozzles 9 are arranged. These nozzles 9 spray with specific... The angle and spacing of the airflow ensures that the sprayed air can evenly cover the surface of the board. The powerful airflow generated by the fan 7, combined with the fine spray of the nozzle 9, can effectively remove dust and impurities from the surface of the board, achieving a fine cleaning effect. At the same time, when the heater 4 is started, the temperature below the shelf 3 rises rapidly, forming a hot air layer. The fan 7 continues to work, spraying the hot air onto the surface of the board through the nozzle 9, further accelerating the drying process and ensuring that the board reaches the ideal dry state in a short time. In order to ensure that the air entering the cleaning box 1 is pure and dust-free, the device is equipped with a filter plate 11 at the air inlet 10. The filter plate 11 is made of high-efficiency filter material, which can effectively intercept and adsorb small particles and dust in the air. Multiple fasteners 12 are also installed on the front and rear sides of the air inlet 10 to firmly fix the filter plate 11 to the top position of the air inlet 10. This design not only enhances the stability and sealing of the filtration system, but also facilitates subsequent maintenance and replacement operations. Through the effective operation of the filtration system, it can be ensured that the air quality entering the cleaning box 1 meets the standard requirements, avoiding dust and other impurities from contaminating the board.

[0041] Reference Figure 1 , Figure 4 and Figure 5The clamping mechanism 2 includes multiple mounting plates 201. Adjacent sides of the mounting plates 201 are fixedly connected to the left and right sides of the cleaning box 1. Rollers 203 are rotatably connected between adjacent mounting plates 201. The rollers 203 on both sides are mounted via the mounting plates 201. A servo motor 202 is fixedly connected to the rear side of the right mounting plate 201. The output end of the servo motor 202 passes through the rear side of the mounting plate 201 and is fixedly connected to the rear end of the roller 203. The servo motor 202 is fixedly mounted via the mounting plates 201 to ensure its robustness and stability. The outer walls of the two rollers 203 are connected via connecting straps 204. Starting the servo motor 202 drives the rollers 203 to rotate synchronously via the connecting straps 204. Multiple mounting blocks 206 are fixedly connected to the outer walls of the two connecting straps 204. Toothed plates 205 and multiple mounting blocks 206 are fixedly connected to the front and rear sides of the interior of the cleaning box 1. Gears 207 are rotatably connected to each adjacent side of the plate, thereby driving the mounting block 206 to mesh and rotate with the gears 207 on the surface of the toothed plate 205. The outer walls of multiple gears 207 are meshed and connected to the top of the toothed plate 205. Fixing frames 208 are fixedly connected between adjacent gears 207. The gears 207 drive the fixing parts 208 fixed between them to rotate, realizing the flipping of the plate and allowing the plate to be cleaned more thoroughly. Sliding grooves 211 are opened on the left and right sides of the fixing frame 208. Clamping plates 210 are slidably connected inside the two sliding grooves 211. Adjusting bolts 209 are threadedly connected to the front and rear sides of the fixing frame 208. The adjacent ends of the two adjusting bolts 209 pass through the front and rear sides of the fixing frame 208 and are threadedly connected to the inner wall of the clamping plate 210. Rotating the adjusting bolts 209 drives the clamping plates 210 in the sliding grooves 211 to move adjacently and away from each other, realizing the clamping and fixing of the plate.

[0042] Specifically, multiple mounting plates 201 are fixed on the left and right sides of the cleaning box 1. These mounting plates 201 not only provide a stable support platform for the entire clamping mechanism, but also serve as key nodes connecting other components. Adjacent mounting plates 201 are connected to rollers 203 through a precision rotating device. These rollers 203 are key components for driving the plate to flip. To ensure that the rollers 203 can work stably and efficiently, a servo motor 202 is fixedly installed on the rear side of the right mounting plate 201. The output end of the servo motor 202 directly passes through the mounting plate 201 and is firmly connected to the rear end of the roller 203. Driven by the servo motor 202, the rollers 203 can achieve precise synchronous rotation, thereby driving the plate to flip. To transmit servo motor power... The power source for the machine 202 is connected to the outer walls of the two rollers 203 by a high-strength connecting belt 204. This connecting belt 204 not only has excellent wear resistance and corrosion resistance, but also maintains stable transmission performance under high-speed operation. When the servo motor 202 starts, the connecting belt 204 quickly transmits power to the two rollers 203, making them rotate synchronously. Multiple mounting blocks 206 are also fixedly connected to the outer wall of the connecting belt 204. The front and rear sides of the interior of the cleaning box 1 are fixedly connected to the toothed plate 205, which closely cooperates with the gear 207 on the mounting block 201. When the servo motor 202 drives the rollers 203 to rotate, the gear 207 will start to mesh and rotate on the surface of the toothed plate 205 through the transmission action of the connecting belt 204 and the mounting block 201. Multiple gears 207 are interconnected and fixed together by a fixing frame 208, forming a stable transmission chain. As the gears 207 rotate, the fixing frame 208 also rotates, thereby causing the plate fixed on it to flip. In order to achieve precise clamping and fixing of the plate, sliding grooves 211 are opened on the left and right sides of the fixing frame 208. Clamping plates 210 are slidably connected inside these sliding grooves 211. The clamping plates 210 are made of high-strength material and the surface is specially treated to increase friction and wear resistance. By adjusting the adjusting bolts 209 connected to the front and rear threads of the fixing frame 208, the distance between the clamping plates 210 can be easily adjusted. When the adjusting bolts 209 rotate, they drive the clamping plates 210 in the sliding grooves 211 to move adjacently or away from each other, thereby achieving firm clamping or release of the plate.

[0043] Reference Figure 1 and Figure 2Multiple observation windows 13 are fixedly connected to the front side of the cleaning box 1. Bolts 14 are threadedly connected to the front side of the multiple observation windows 13. The observation windows 13 are installed and fixed by the multiple bolts 14. The observation windows 13 can be conveniently observed to observe the internal cleaning status. A support frame 15 is fixedly connected to the bottom of the cleaning box 1. Multiple rubber pads 16 are fixedly connected to the bottom end of the support frame 15. The support frame 15 supports and fixes the entire device, improving the stability of the device. A collection box 17 is slidably connected to the top right side of the support frame 15. The left and right sides of the collection box 17 are provided with buckle grooves 18. A control box 20 is fixedly connected to the front side of the support frame 15. The control box 20 is electrically connected to the servo motor 202, heater 4 and fan 7 respectively. A placement rack 19 is fixedly connected to the front side of the support frame 15. The top of the placement rack 19 is fixedly connected to the bottom of the control box 20. The control box 20 can be used to conveniently operate and control the operating equipment on the entire device.

[0044] Specifically, observation windows 13 are evenly distributed on the front side of the cleaning box, ensuring that the operator can clearly observe the cleaning status inside the box from different angles. The front side of each observation window 13 is tightly connected to bolts 14 through a precise threaded connection. This connection method not only ensures the stable installation of the observation window 13, but also facilitates disassembly and maintenance when needed. A support frame 15 is fixedly connected to the bottom of the cleaning box 1. The support frame 15 can withstand the weight of the entire device and various forces during operation. The rubber pad 16 not only increases the contact area with the ground and improves the stability of the device, but also has the function of shock absorption and noise reduction, effectively reducing the impact of vibration and noise during equipment operation on the surrounding environment. The control box 20 realizes real-time monitoring and precise control of the entire device's operating status.

[0045] Working principle: First, the blower 7 is started to draw in outside air through connecting pipe 6, and after being pressurized, it is delivered to the bottom of the cleaning box 1 through connecting pipe 8. At the end of connecting pipe 8, multiple precision-designed nozzles 9 are arranged. The airflow from the nozzles 9 can evenly cover the surface of the board. The powerful airflow generated by the blower 7, combined with the fine spray from the nozzles 9, can effectively remove dust and impurities from the surface of the board, achieving a fine cleaning effect. At the same time, the heater 4 is started, and the temperature below the shelf 3 rises rapidly, forming a hot air layer. The blower 7 continues to work, spraying the hot air onto the board through the nozzles 9. The surface of the material is further accelerated to ensure that the board reaches the ideal drying state in a short time. The servo motor 202 is started to drive the roller 203 to rotate synchronously with the connecting belt 204, thereby driving the mounting block 206 to mesh with the gear 207 on the surface of the toothed plate 205. The gear 207 drives the fixed part 208 to rotate, realizing the flipping process of the board, so that the board can be cleaned more thoroughly. The rotating adjusting bolt 209 drives the clamping plate 210 in the sliding groove 211 to move adjacently and away from each other, realizing the clamping and fixing of the board.
