Description

Technical Field

[0001] This utility model belongs to the field of servo driver technology, and in particular relates to a servo driver with dustproof function. Background Technology

[0002] A servo drive is a controller used to control a servo motor. However, servo drives generate heat during long-term operation, so heat dissipation holes need to be opened inside their housing for heat dissipation. At this time, dust in the outside air can enter the servo drive through the heat dissipation holes. In order to prevent damage to the lifespan and performance of the internal components, dustproof treatment is required for the heat dissipation holes.

[0003] For example, Chinese patent document (CN213350009U) discloses a dust removal device for a servo drive to improve heat dissipation performance. This device includes a servo drive body, a drive motor, a lead screw, and a storage box. The drive motor is located at the center of one side of the servo drive body, with a lead screw at one end and the servo drive body itself at the other end. The storage box is located inside one side of the servo drive body, with a circuit board at the bottom of one side and a fan at the center of the circuit board. This dust removal device for a servo drive improves heat dissipation performance by moving the lead screw and a moving block during dust removal. The moving block is connected to an upper and lower dust removal rod, which facilitates dust removal from the surface and inner walls of the servo drive body, improving the cleanliness of the interior. However, during use, dust generated during the cleaning process of the upper and lower dust removal rods on the heat dissipation grille may enter the drive due to the fan's airflow, affecting the dustproof effect. Therefore, improvements are needed. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A servo driver with dustproof function includes a driver housing, and dustproof boxes are fixedly connected to both sides of the driver housing. The dustproof boxes are respectively provided with a first through hole and a first cavity. A dustproof component is provided inside the first cavity, and a dust removal component is provided on one side of the dustproof component.

[0007] The dust removal assembly includes a fixed block that is slidably connected inside the dustproof box. A fixed frame is fixedly connected to the fixed block on the side away from the center of the dustproof box. Multiple air outlets are opened on one side of the fixed frame, and a second cavity is connected to the bottom of the fixed frame. An air outlet pipe is connected to one side of the second cavity, and an air bladder is connected to the other end of the air outlet pipe. A vertical plate is provided on one side of the air bladder, and a rack is fixedly connected to the top of the vertical plate. Multiple gears are meshed on one side of the top of the rack, and a rotating shaft is fixedly connected inside the gears. The rotating shaft is rotatably connected inside the dustproof box, and one end of the rotating shaft extends into the first through hole and is fixedly connected to a blade.

[0008] As a further description of the above technical solution:

[0009] The dustproof component includes a cam, which is disposed inside the first cavity and a rotating shaft is fixedly connected inside the cam. One end of the rotating shaft extends into the inside of the driver housing and is fixedly connected to a drive motor. The bottom of the drive motor is fixedly connected to the inner wall of the driver housing through a support seat. A second through hole is provided on both sides inside the driver housing, and the second through hole and the first through hole are on the same axis.

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

[0011] Sliding plates are provided on both sides of the cam. The sliding plates are slidably connected to the inside of the dustproof box. A connecting block is fixedly connected to the side of the sliding plate away from the cam. A spring is provided on one side of the connecting block. The two sides of the spring are fixedly connected to the sliding plate and the inner wall of the dustproof box, respectively.

[0012] As a further description of the above technical solution:

[0013] The other side of the connecting block extends into the first through hole and is fixedly connected to a cleaning block. A dustproof net is provided on one side of the cleaning block. The dustproof net is located inside the first through hole and is fixedly connected to the inner wall of the dustproof box.

[0014] As a further description of the above technical solution:

[0015] Both the dustproof net and the fixing block are located on the side opposite to the driver housing, with the dustproof net positioned between the cleaning block and the fixing block. The connecting block is slidably connected inside the dustproof box.

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

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the dust removal components enable the sliding plate to move the fixed block, fixed frame, vertical plate, and rack away from the center of the dustproof box.

At the same time, the sliding plate sprays the gas inside the airbag through the air outlet pipe, the second cavity, the fixed frame, and multiple air outlets onto the surface of the dustproof net. Combined with the cleaning action of the cleaning block on the dustproof net, the cleaning effect on the dustproof net is improved. This prevents some dust from entering the driver housing due to the radiator's suction effect when the cleaning block is cleaning the dustproof net, thus preventing the overall dustproof effect of the device from being affected.

[0020] 2. In this utility model, the dustproof component filters the gas entering the drive housing, preventing external dust from entering and thus preventing dust from affecting the service life and stability of the electronic components inside the drive housing. The drive motor drives the rotating shaft and cam to rotate, causing the sliding plate to move the connecting block and cleaning block up and down on the surface of the dustproof net to clean the surface of the dustproof net. This prevents a large amount of dust from adhering to the dustproof net after long-term use, which would cause blockage and thus affect the dustproof effect and heat dissipation efficiency of the device.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a servo driver with dustproof function, including a driver housing 1, dustproof boxes 2 are fixedly connected to both sides of the driver housing 1, a first through hole 3 and a first cavity 4 are respectively opened inside the dustproof box 2, a dustproof component 5 is arranged inside the first cavity 4, and a dust removal component 6 is arranged on one side of the dustproof component 5.

[0029] The dust removal component 6 includes a fixing block 601, which is slidably connected inside the dustproof box 2. A fixing frame 603 is fixedly connected to the side of the fixing block 601 away from the center of the dustproof box 2. Multiple air outlets 605 are opened on one side of the fixing frame 603, and a second cavity 604 is connected to the bottom of the fixing frame 603. An air outlet pipe is connected to one side of the second cavity 604, and an air bag 606 is connected to the other end of the air outlet pipe. A vertical plate 607 is provided on one side of the air bag 606, and a rack 608 is fixedly connected to the top of the vertical plate 607. Multiple gears 609 are meshed on one side of the top of the rack 608, and a gear 609 is fixedly connected inside the gear 609. A rotating shaft 610 is rotatably connected inside the dustproof box 2, and one end of the rotating shaft 610 extends into the first through hole 3 and is fixedly connected to a blade 602. An airbag 606 is disposed inside the first cavity 4, and the cross-section of the airbag 606 is rectangular. The two sides of the airbag 606 are fixedly connected to one side of the sliding plate 504 and the inner wall of the dustproof box 2, respectively. An air inlet pipe is connected to one side of the airbag 606. One-way valves are provided on both the air inlet pipe and the air outlet pipe. The bottom of the vertical plate 607 is fixedly connected to the top of the sliding plate 504. The second cavity 604 is located inside the fixed block 601 and is connected to the air outlet 605.

[0030] Detailed Implementation: First, place the driver housing 1 in a suitable external location. When the internal temperature of the driver housing 1 is high, external cold air is drawn into the driver housing 1 through the built-in heat sink, first through hole 3, and second through hole to increase airflow inside the driver housing 1 for heat dissipation. This causes the sliding plate 504 to move the fixed block 601, fixed frame 603, vertical plate 607, and rack 608 away from the center of the dustproof box 2. Utilizing the linkage effect between the rack 608 and gear 609, power is transmitted to the gear 609, causing the gear 609 to drive the rotating shaft 610 and blade 602 to rotate. The blade 602 seals the first through hole 3 on one side, at which point the heat sink... The first through hole 3 and the second through hole on one side draw in external cold air to maintain continuous heat exchange inside the driver housing 1. At the same time, the sliding plate 504 squeezes the airbag 606, transporting the gas inside the airbag 606 to the second cavity 604 through the air outlet pipe. Then, it is sprayed onto the surface of the dustproof net 508 through the fixing frame 603 and multiple air outlets 605. Combined with the cleaning block 506 cleaning the dustproof net 508, the cleaning effect on the dustproof net 508 is further improved. This prevents some dust from entering the driver housing 1 through the first through hole 3 and the second through hole when the cleaning block 506 is cleaning the dustproof net 508 due to the exhaust effect of the radiator, thereby preventing the overall dustproof effect of the device from being affected.

[0031] The dustproof component 5 includes a cam 501, which is disposed inside the first cavity 4. A rotating shaft 502 is fixedly connected inside the cam 501. One end of the rotating shaft 502 extends into the driver housing 1 and is fixedly connected to a drive motor 503. The bottom of the drive motor 503 is fixedly connected to the inner wall of the driver housing 1 via a support base. Second through holes are provided on both sides of the driver housing 1. The second through holes and the first through hole 3 are on the same axis. Sliding plates 504 are provided on both sides of the cam 501. The sliding plates 504 are slidably connected inside the dustproof box 2. A connecting block 505 is fixedly connected to the side of the sliding plate 504 away from the cam 501. A spring 507 is provided on one side of the 05. The two sides of the spring 507 are fixedly connected to the sliding plate 504 and the inner wall of the dustproof box 2, respectively. The other side of the connecting block 505 extends into the first through hole 3 and is fixedly connected to the cleaning block 506. A dustproof net 508 is provided on one side of the cleaning block 506. The dustproof net 508 is located inside the first through hole 3 and is fixedly connected to the inner wall of the dustproof box 2. The other side of the connecting block 505 extends into the first through hole 3 and is fixedly connected to the cleaning block 506. A dustproof net 508 is provided on one side of the cleaning block 506. The dustproof net 508 is located inside the first through hole 3 and is fixedly connected to the inner wall of the dustproof box 2.

[0032] Detailed implementation: The dustproof net 508 filters the gas entering the driver housing 1 to prevent external dust from entering the driver housing 1, thereby preventing dust from affecting the service life and operational stability of the electronic components inside the driver housing 1. The drive motor 503 is started as needed, which drives the rotating shaft 502 and the cam 501 to rotate. During the rotation, the cam 501 squeezes the sliding plate 504 and the spring 507 in sequence, causing the sliding plate 504 to drive the connecting block 505 and the cleaning block 506 to move up and down on the surface of the dustproof net 508 to clean the surface of the dustproof net 508. This prevents a large amount of dust from adhering to the dustproof net 508 after long-term use, which would cause blockage and affect the dustproof effect and heat dissipation efficiency of the device.

[0033] Working Principle: In use, first place the driver housing 1 in a suitable external location. When the internal temperature of the driver housing 1 is high, cool external air is drawn into the driver housing 1 through the built-in heat sink, first through-hole 3, and second through-hole to increase airflow. The dust filter 508 filters the air entering the driver housing 1. As needed, the drive motor 503 is activated, driving the rotating shaft 502 and cam 501 to rotate. During rotation, the cam 501 sequentially presses the sliding plate 504 and spring 507, causing the sliding plate 504 to move the connecting block 505 and cleaning block 506 up and down on the surface of the dust filter 508 to clean it. Simultaneously, the sliding plate 504 drives the fixing block 601 and fixing frame 60... 3. The vertical plate 607 and rack 608 move away from the center of the dustproof box 2. Utilizing the linkage effect between the rack 608 and gear 609, power is transmitted to the gear 609, causing the gear 609 to drive the rotating shaft 610 and blade 602 to rotate. The blade 602 seals the first through hole 3 on one side. At this time, the radiator draws in external cold air through the first through hole 3 and the second through hole on one side to maintain continuous heat exchange inside the driver housing 1. At the same time, the sliding plate 504 squeezes the airbag 606, transporting the gas inside the airbag 606 to the second cavity 604 through the air outlet pipe. Then, it is sprayed onto the surface of the dustproof net 508 through the fixed frame 603 and multiple air outlets 605. Combined with the cleaning block 506 cleaning the dustproof net 508, the cleaning effect on the dustproof net 508 is further improved.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
