Description

Technical Field

[0001] This utility model relates to the field of brazing plate processing technology, specifically a dust removal device for brazing plate processing. Background Technology

[0002] In the production process of heat sinks, the heat conduction efficiency of heat sinks can be improved by connecting the fins with brazing plates. During the processing of brazing plates, dust removal is required after the brazing seams are ground to ensure the subsequent processing of the brazing plates. Therefore, a dust removal device is needed.

[0003] A Chinese patent with authorization announcement number CN118438302A discloses an infrared template grinding dust removal device, including a dust removal machine and a perforated table. The dust removal machine has a support rod shaft and two movable partitions inside, forming a dust suction chamber between the two movable partitions. Each movable partition is equipped with a dust suction component. The device also includes two dust cleaning components and at least one pushing component. The pushing component can drive the guide rotation component to move vertically back and forth on the outer wall of the dust removal machine. The support rod shaft can rotate as it moves back and forth with the guide rotation component. The dust cleaning component can clean dust particles on the suction end surface of the dust suction component. This invention can adjust the position and size of the dust suction chamber according to the grinding area, ensuring that the airflow enters the dust suction chamber through the grinding area, effectively removing dust. Furthermore, the perforated table shakes and swings slightly to clean residual debris and dust particles. The device is easy to operate and highly practical.

[0004] However, the aforementioned dust removal devices still have some problems. In practical applications, brazed plates have uneven surfaces and raised weld seams. The existing dust collection hoods are rigid structures that cannot adapt to brazed plates, which reduces the dust removal effect and affects the working environment. Therefore, a dust removal device for brazed plate processing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a dust removal device for brazing plate processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A dust removal device for brazing plate processing according to this utility model includes a workbench. A cylinder is installed directly above the top side of the workbench. A mounting frame is installed at the working end of the cylinder. Mounting plates are installed on both sides of the mounting frame. Sliding rods are installed at both ends of the mounting plates. Limiting blocks are installed at the top of each sliding rod. Springs are fixed between each limiting block and the mounting plate. The springs are fitted onto the outside of the sliding rods. A dust suction hood is installed at the bottom end of the sliding rod of each mounting plate. Side plates are installed on both sides of the dust suction hood. A support frame is installed on the bottom side of each side plate. The support frame has rollers installed on both sides via pins. A dust conveying pipe, which is a telescopic corrugated pipe, is installed on the top side of each dust hood. A cylinder drives the mounting frame and dust hood to descend. During descent, a sliding rod slides on the mounting plate, and a spring stretches, allowing the dust hood to adaptively adjust its height according to the surface of the brazed board. Combined with the telescopic corrugated pipe, this enables flexible height adjustment of the dust hood during operation, improving its adaptability and allowing it to better conform to the surface of the brazed board for dust collection. This effectively improves the dust removal effect during brazed board processing, reduces dust emissions, and ensures a clean working environment.

[0007] Preferably, a grinding motor is installed on one side of the mounting bracket, and a grinding roller is installed at the output end of the grinding motor. Dust hoods are located on both sides of the grinding roller. The grinding motor drives the grinding roller to rotate, and the dust hoods are located on both sides of the grinding roller. When the grinding motor drives the grinding roller to perform grinding operations on the weld seam of the brazed plate, the dust hoods on both sides can promptly suck away the dust generated during grinding, prevent the dust from spreading, further improve the dust removal effect, and ensure the smooth progress of the grinding operation.

[0008] Preferably, a fixed frame is installed on both sides of the workbench. A reciprocating motor is installed at one end of the top side of the fixed frame, and a threaded rod is installed at the output end of the reciprocating motor. A slide rail is provided inside the top side of the fixed frame, and a slider is slidably installed inside the slide rail. A threaded hole is provided inside the slider. One end of the threaded rod passes through the threaded hole and is rotatably installed inside one side of the slide rail. A cylinder is installed on the bottom side of the slider. The reciprocating motor drives the threaded rod to rotate, and the slider slides in the slide rail through the threaded hole and the threaded rod, thereby driving the grinding roller to reciprocate. This allows the grinding roller to evenly grind the surface of the brazed board, expand the grinding range, improve the grinding effect of the brazed board, and ensure that the surface of the brazed board is flat and smooth.

[0009] Preferably, dust collection boxes are installed on both sides of the fixing frame, one end of the dust conveying pipe is connected to the top side of the dust collection box, a filter screen is installed inside the middle of the dust collection box, a negative pressure motor is installed inside the bottom side of the dust collection box, three fan blades are installed at the output end of the negative pressure motor, a movable door is installed on one side of the dust collection box through a hinge, a handle is installed on one side of the movable door, and an exhaust hole is opened on one side of the dust collection box. The negative pressure motor drives the fan blades to rotate and generate negative pressure, which concentrates the dust adsorbed by the dust collection hood into the dust collection box. The filter screen can filter the dust and prevent the dust from being discharged with the airflow. Clean air is discharged through the exhaust hole. The design of the movable door and handle makes it convenient to clean the dust in the dust collection box.

[0010] Preferably, the workbench has an internal mounting groove, a support block is installed on the bottom inner wall of the mounting groove, a drive motor is installed on the top of the support block, and a gear is installed on the output end of the drive motor. Two sliding grooves are symmetrically opened on the top side of the workbench, communicating with the mounting groove. Fixed clamping plates are slidably installed inside each sliding groove. A silicone pad is installed on one side of the top of each fixed clamping plate, and a rack is installed on one side of the bottom of each fixed clamping plate. The racks are symmetrically arranged around a central axis and mesh with the gears. A rectangular groove is opened inside the bottom side of the mounting groove, and a moving block is slidably installed inside the rectangular groove. One rack is installed on the top side of the moving block, and a through hole is opened at the middle of one of the fixed clamping plates. The drive motor drives the gear to rotate, and the two racks meshing with the gear respectively drive the two fixed clamping plates to slide towards or away from each other in the sliding groove, achieving clamping and fixing of brazing plates of different sizes. The silicone pad increases the friction between the fixed clamping plate and the brazing plate, while preventing scratches on the surface of the brazing plate. The through hole does not affect the movement of the other rack.

[0011] Preferably, a control panel is installed on one side of the mounting bracket. The control panel is electrically connected to the electrical components inside the device and is used to operate and control the electrical components inside the device. Operators can centrally operate and control the electrical components inside the device, such as cylinders, grinding motors, reciprocating motors, negative pressure motors, and drive motors, through the control panel, which improves the convenience and accuracy of operation.

[0012] The advantages of this utility model are:

[0013] 1. During grinding, the rollers of this utility model move along the surface of the brazed plate. If there are slight undulations on the surface of the brazed plate, the slide bar slides inside the mounting plate, and the spring automatically adjusts the height of the dust hood through extension and retraction. The dust hood is always close to the surface of the plate to prevent dust from escaping. This ensures that the height of the dust hood can be flexibly adjusted during operation, improving the adaptability of the dust hood and enabling it to better fit the surface of the brazed plate for dust collection. This effectively improves the dust removal effect of brazed plate processing, reduces dust flying, and ensures a clean working environment.

[0014] 2. This utility model starts the drive motor, and the output end of the drive motor drives the gear to rotate. When the gear rotates, the racks on both sides move in opposite directions. The racks drive the fixed clamping plate to slide in the slide groove, and the moving block slides synchronously in the rectangular groove, ensuring the stable movement of the rack at the bottom end. This achieves the clamping of the brazing plate by the two fixed clamping plates, and the silicone pad avoids scratching the plate. Because the racks are symmetrically arranged, they can be adapted to brazing plates of different sizes, ensuring the stability of the brazing plate grinding process. One of the fixed clamping plates has a through hole to avoid the grinding roller, preventing collision with the clamping plate during grinding and ensuring unobstructed grinding operation.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a dust removal device for brazing plate processing includes a workbench 1. A cylinder 2 is mounted directly above the top side of the workbench 1. A mounting bracket 201 is mounted on the actuating end of the cylinder 2. Mounting plates 202 are mounted on both sides of the mounting bracket 201. Slide rods 203 are mounted on both ends of the mounting plates 202. Limiting blocks 204 are mounted on the top of each slide rod 203. Springs 205 are fixedly connected between each limiting block 204 and the mounting plate 202. Spring 205 is fitted onto the outside of slide rod 203. A dust suction hood 206 is mounted at the bottom end of the slide rod 203 on each mounting plate 202. Side plates 207 are mounted on both sides of the dust suction hood 206. A support frame 208 is mounted on the bottom side of the side plate 207. Rollers 209 are mounted between the two sides of the support frame 208 via pins. A dust conveying pipe 210, which is a telescopic corrugated pipe, is mounted on the top side of each dust suction hood 206.

[0024] Dust collection boxes 5 are installed on both sides of the fixing frame 4. One end of the dust conveying pipe 210 is connected to the top side of the dust collection box 5. A filter screen 501 is installed inside the middle of the dust collection box 5. A negative pressure motor 502 is installed inside the bottom side of the dust collection box 5. Three fan blades 503 are installed at the output end of the negative pressure motor 502. A movable door 504 is installed on one side of the dust collection box 5 via a hinge. A handle 505 is installed on one side of the movable door 504. An exhaust port 506 is opened on one side of the dust collection box 5.

[0025] A control panel 7 is installed on one side of the fixed frame 4. The control panel 7 is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device. In actual application, the brazed plate has an uneven surface and raised weld seams. In the prior art, the dust hood 206 is a rigid structure and cannot adapt to the brazed plate, which will reduce the dust removal effect and affect the working environment. During the grinding process, the roller 209 will move along the surface of the brazed plate. If the surface of the brazed plate has slight undulations, the slide bar 203 slides in the mounting plate 202, and the spring 205 automatically adjusts the height of the dust hood 206 by extension and retraction. The dust hood 206 is always close to the surface of the plate to prevent dust from escaping. This ensures that the height of the dust hood 206 can be flexibly adjusted during operation, which improves the adaptability of the dust hood 206. It can better fit the surface of the brazed plate for dust removal, effectively improve the dust removal effect of brazed plate processing, reduce dust flying, and ensure a clean working environment.

[0026] During vacuuming operations, the negative pressure motor 502 starts simultaneously with the operation of the grinding motor 3, driving the three fan blades 503 to rotate, creating a negative pressure inside the dust collection box 5. Air is then drawn into the dust collection hood 206 through the dust conveying pipe 210. When the grinding motor 3 drives the grinding roller 301 to grind the weld seam, the generated dust spreads to both sides. The dust collection hood 206 is located on both sides of the grinding roller 301. Under the action of negative pressure, the dust is directly drawn into the dust collection hood 206. The dust is carried by the airflow through the dust conveying pipe 210 into the dust collection box 5, filtered by the filter screen 501 to intercept dust particles, and clean air is discharged from the exhaust port 506. Later, the movable door 504 can be opened by the handle 505 to clean the dust inside the dust collection box 5. The telescopic corrugated state of the dust conveying pipe 210 can prevent the pipe from getting stuck when the vacuuming components move.

[0027] Please see Figure 1 , 2 As shown in Figures 3 and 5, a grinding motor 3 is mounted on one side of the mounting bracket 201, and a grinding roller 301 is mounted on the output end of the grinding motor 3. The dust collection hoods 206 are located on both sides of the grinding roller 301.

[0028] The workbench 1 is fitted with a fixed frame 4 on both sides. A reciprocating motor 401 is mounted on one top end of the fixed frame 4. A threaded rod 402 is mounted on the output end of the reciprocating motor 401. A slide rail 403 is provided inside the top side of the fixed frame 4. A slider 404 is slidably mounted inside the slide rail 403. A threaded hole is provided inside the slider 404. One end of the threaded rod 402 passes through the threaded hole and is rotatably mounted inside one side of the slide rail 403. The cylinder 2 is mounted on the bottom side of the slider 404.

[0029] The workbench 1 has an internal mounting groove 6. A support block 601 is mounted on the bottom inner wall of the mounting groove 6. A drive motor 602 is mounted on the top of the support block 601. A gear 603 is mounted on the output end of the drive motor 602. Two sliding grooves 604 are symmetrically formed on the top side of the workbench 1, communicating with the mounting groove 6. A fixing plate 605 is slidably mounted inside each sliding groove 604. A silicone pad 606 is mounted on one side of the top of each fixing plate 605. Each of the bottom sides of the heat sink is equipped with a rack 607, which are symmetrically arranged around the central axis. Each rack 607 meshes with a gear 603. A rectangular groove 608 is formed inside the bottom side of the mounting groove 6, and a moving block 609 is slidably installed inside the rectangular groove 608. One rack 607 is mounted on the top side of the moving block 609. A through hole 610 is formed at the middle of one of the fixing plates 605. During operation, in the heat sink manufacturing process, after the fins are connected by a brazing plate, the heat sink can... To improve the heat transfer efficiency of the heat sink, a dust removal process is required after the brazing seam is ground during the processing of the brazed plate to ensure the smooth operation of subsequent processing. Therefore, a dust removal device is needed. The brazed plate is placed on the top side of the workbench 1, and the drive motor 602 is started. The output of the drive motor 602 drives the gear 603 to rotate. The gear 603 meshes with the racks 607 on both sides, which are centrally symmetrical. When the gear 603 rotates, the racks 607 on both sides move in opposite directions, and the racks 607 drive the fixed clamp. Plate 605 slides in groove 604, and moving block 609 slides synchronously in rectangular groove 608, ensuring stable movement of rack 607 at the bottom end, realizing clamping of brazing plate by two fixed clamping plates 605, and silicone pad 606 avoids scratching the plate. Because rack 607 is symmetrically arranged, it can be adapted to brazing plates of different sizes, ensuring stability during the grinding process of brazing plate. The through hole 610 of one of the fixed clamping plates 605 is used to avoid the grinding roller 301, avoiding collision with the clamping plate during grinding, and ensuring unobstructed grinding operation.

[0030] The reciprocating motor 401 is started, and its output end drives the threaded rod 402 to rotate. When the threaded rod 402 rotates, the slider 404 moves linearly back and forth along the slide rail 403. The slider 404 moves synchronously with the slider 404. The cylinder 2 is extended and retracted through the control panel 7, which drives the mounting bracket 201 and the grinding motor 3 and dust hood 206 below to rise and fall, so that the grinding roller 301 fits the height of the brazed plate weld. The grinding motor 3 is started, and its output end drives the grinding roller 301 to rotate at high speed. The material of the grinding roller 301 is adapted to the brazed plate to ensure that the weld is ground flat. The reciprocating motor 401 continues to drive the threaded rod 402 to rotate, and the slider 404 drives the grinding roller 301 to move back and forth along the length of the brazed plate, so that the grinding roller 301 evenly covers the weld area and avoids local over-grinding or missed grinding.

[0031] Working principle: The brazing plate is placed on the top side of the workbench 1. The drive motor 602 is started. The output end of the drive motor 602 drives the gear 603 to rotate. The gear 603 meshes with the racks 607 on both sides that are centrally symmetrical. When the gear 603 rotates, the racks 607 on both sides move in opposite directions. The racks 607 drive the fixed clamping plate 605 to slide in the slide groove 604. The moving block 609 slides synchronously in the rectangular groove 608 to ensure the stable movement of the rack 607 at the bottom end. This achieves the clamping of the brazing plate by the two fixed clamping plates 605. The silicone pad 606 avoids scratching the plate. Because the racks 607 are symmetrically arranged, they can be adapted to brazing plates of different sizes, ensuring the stability of the brazing plate grinding process. The through hole 610 of one of the fixed clamping plates 605 is used to avoid the grinding roller 301, preventing it from colliding with the clamping plate during grinding and ensuring that the grinding operation is unobstructed.

[0032] The reciprocating motor 401 is started, and its output drives the threaded rod 402 to rotate. When the threaded rod 402 rotates, the slider 404 moves linearly back and forth along the slide rail 403. The slider 404 moves synchronously with the slider 404. The cylinder 2 is extended and retracted through the control panel 7, which drives the mounting bracket 201 and the grinding motor 3 and dust hood 206 below it to rise and fall, so that the grinding roller 301 fits the height of the brazed plate weld. The grinding motor 3 is started, and its output drives the grinding roller 301 to rotate at high speed. The material of the grinding roller 301 is adapted to the brazed plate to ensure that the weld is ground flat. The reciprocating motor 401 continues to drive the threaded rod 402 to rotate, and the slider 404 drives the grinding roller 301 to move back and forth along the length of the brazed plate, so that the grinding roller 301 evenly covers the weld area, avoiding local over-grinding or missed grinding.

[0033] During the grinding process, the roller 209 moves along the surface of the brazed plate. If there are slight undulations on the surface of the brazed plate, the slide bar 203 slides within the mounting plate 202, and the spring 205 automatically adjusts the height of the dust hood 206 by extension and retraction. The dust hood 206 is always close to the surface of the plate to prevent dust from escaping. This ensures that the height of the dust hood 206 can be flexibly adjusted during operation, improving the adaptability of the dust hood 206. It can better fit the surface of the brazed plate for dust collection, effectively improving the dust removal effect of brazed plate processing, reducing dust flying, and ensuring a clean working environment.

[0034] During vacuuming operations, the negative pressure motor 502 starts simultaneously with the operation of the grinding motor 3, driving the three fan blades 503 to rotate, creating a negative pressure inside the dust collection box 5. Air is then drawn into the dust collection hood 206 through the dust conveying pipe 210. When the grinding motor 3 drives the grinding roller 301 to grind the weld seam, the generated dust spreads to both sides. The dust collection hood 206 is located on both sides of the grinding roller 301. Under the action of negative pressure, the dust is directly drawn into the dust collection hood 206. The dust is carried by the airflow through the dust conveying pipe 210 into the dust collection box 5, filtered by the filter screen 501 to intercept dust particles, and clean air is discharged from the exhaust port 506. Later, the movable door 504 can be opened by the handle 505 to clean the dust inside the dust collection box 5. The telescopic corrugated state of the dust conveying pipe 210 can prevent the pipe from getting stuck when the vacuuming components move.
