Description

Technical Field

[0001] This utility model relates to the field of control board cleaning technology, and in particular to a cleaning device for a motor-driven control board. Background Technology

[0002] With the acceleration of industrial automation, motor drive control systems are increasingly widely used in rail transit, intelligent equipment, and new energy vehicles. As a core component, the motor drive control board's operational stability directly affects equipment performance. However, during long-term operation, the control board is prone to accumulating dust, oil, and metal debris, leading to poor heat dissipation, decreased insulation performance, and even short-circuit faults. Therefore, regular cleaning is necessary. Currently, cleaning methods mostly involve manual brushing and blowing with an insulated brush and fan. This method requires two hands—one to hold the fan and the other the brush—making it inconvenient. Furthermore, the airflow is obstructed by the brush, preventing direct targeting of the cleaning area and resulting in poor cleaning effectiveness. Utility Model Content

Several fixing rods are fixedly connected to both sides of the bottom of the inner wall of the positioning frame. An air-inflating piston is fixedly connected to one end of each fixing rod away from the inner wall of the positioning frame. A sliding block is movably connected to the inner wall of the positioning frame. Several piston holes are opened on both sides of the sliding block.

[0006] The technical effect achieved by adopting the above solution is that the solution allows for easy gripping and operation via the handle, thereby enabling the insulating bristles to contact the circuit board surface.

[0007] Preferably, in any of the above solutions, the length of the sliding block is less than the length of the inner wall of the positioning frame, the distance between the two sides of the sliding block and the two sides of the inner wall of the positioning frame is half the depth of the inner wall of the piston hole, and the sum of the lengths of the fixing rod and the air-inflating piston is adapted to the depth of the piston hole.

[0008] The technical effect achieved by adopting the above solution is that the sliding stroke of the sliding block on the inner wall of the positioning frame can be matched with the sliding stroke of the air piston on the inner wall of the piston hole.

[0009] Preferably, in any of the above schemes, the sum of the internal volumes of the plurality of piston holes is greater than twice the inner wall volume of the venting partition, the distribution area of ​​the venting partition is adapted to the range of the bottom surface of the sliding block, and the distribution range of the plurality of exhaust micro-holes and the plurality of insulating bristles is adapted to the range of the bottom surface of the sliding block.

[0010] The technical effect achieved by adopting the above solution is that by using this solution, the input airflow inside the piston hole can be greater than the internal space of the ventilation partition, which can increase the pressure of the output airflow and improve the blowing effect.

[0021] like Figures 1 to 3As shown, a cleaning device for a motor drive control board includes a positioning frame 1. Several fixing rods 13 are fixedly connected to both sides of the bottom of the inner wall of the positioning frame 1. An air-inflating piston 14 is fixedly connected to one end of each fixing rod 13 away from the inner wall of the positioning frame 1. A sliding block 2 is movably connected to the inner wall of the positioning frame 1. Several piston holes 15 are opened on both sides of the sliding block 2. The air-inflating pistons 14 at one end of each fixing rod 13 are slidably connected to the piston holes 15. An air inlet one-way valve 11 is fixedly connected to the top of one end of the inner wall of each piston hole 15, and an air outlet one-way valve 16 is fixedly connected to the bottom of one end of the inner wall of each piston hole 15. A ventilation partition 17 is opened at the bottom inside the sliding block 2. The output end of the air outlet one-way valve 16 is connected to the ventilation partition. The interior of layer 17 is interconnected. The bottom surface of sliding block 2 is provided with several exhaust micro-holes 12, which are all connected to the interior of the ventilation partition 17. Several insulating bristles 10 are fixedly connected to the bottom surface of sliding block 2. The several insulating bristles 10 and several exhaust micro-holes 12 are arranged alternately. The air inlet end of the air inlet one-way valve 11 passes through the top surface of sliding block 2. A connecting column 3 is fixedly connected to the center of the top surface of sliding block 2. A support plate 4 is fixedly connected to the center of one side of the top surface of positioning frame 1. A drive motor 5 is fixedly connected to the center of the top surface of support plate 4. A turntable 6 is fixedly connected to the output end of drive motor 5. A connecting shaft 7 is fixedly connected to the edge of the bottom surface of turntable 6. A connecting rod 8 is rotatably connected between connecting shaft 7 and connecting column 3.

[0022] As an optional technical solution of this utility model, an operating handle 9 is fixedly connected to the middle of the top surface of the positioning frame 1. The width of the sliding block 2 is adapted to the width of the inner wall of the positioning frame 1. The bottom surface of the sliding block 2 is flush with the bottom surface of the positioning frame 1. Several insulating bristles 10 protrude from the bottom surface of the sliding block 2. The operating handle 9 facilitates gripping and operation, thereby allowing the insulating bristles 10 to contact the surface of the circuit board.

[0023] As an optional technical solution of this utility model, the length of the sliding block 2 is less than the length of the inner wall of the positioning frame 1, the distance between the two sides of the sliding block 2 and the two sides of the inner wall of the positioning frame 1 is half the depth of the inner wall of the piston hole 15, and the sum of the lengths of the fixing rod 13 and the air-inflating piston 14 is adapted to the depth of the piston hole 15, so that the sliding stroke of the sliding block 2 on the inner wall of the positioning frame 1 and the sliding stroke of the air-inflating piston 14 on the inner wall of the piston hole 15 are matched.

[0024] As an optional technical solution of this utility model, the sum of the internal volumes of a plurality of piston holes 15 is greater than twice the internal volume of the ventilation partition 17. The distribution area of ​​the ventilation partition 17 is adapted to the range of the bottom surface of the sliding block 2. The distribution range of a plurality of exhaust micro-holes 12 and a plurality of insulating bristles 10 is adapted to the range of the bottom surface of the sliding block 2. This makes the airflow input inside the piston holes 15 greater than the internal space of the ventilation partition 17, which can increase the pressure of the output airflow and improve the blowing effect.

[0025] As an optional technical solution of this utility model, the position of the center of the turntable 6 corresponds to the position of the connecting column 3, and the radius of the turntable 6 is adapted to half the depth of the inner wall of the piston hole 15, so that the reciprocating stroke of the turntable 6 driving the sliding block 2 to slide matches the sliding stroke of the inner wall of the piston hole 15.

[0026] The cleaning device for this motor drive control board requires the following steps to use:

[0027] 1) The drive motor 5 drives the turntable 6 to rotate, and the connecting rod 8 pulls the sliding block 2 to slide back and forth, thereby driving several insulating bristles 10 to automatically brush back and forth.

[0028] 2) By sliding the sliding block 2 back and forth, it can drive several piston holes 15 to slide relative to the air pumping piston 14, thereby continuously compressing the airflow inside the piston hole 15 and introducing it into the ventilation partition 17 through the exhaust one-way valve 16.

[0029] 3) Through the distribution of the ventilation layer 17, the airflow is output from a number of exhaust micro-holes 12, so that the compressed airflow rushes from the exhaust micro-holes 12 between a number of insulating bristles 10 to the sweeping position, thereby blowing directly on the brush-sweeping contact position while brushing, thus effectively cleaning the sweeping position efficiently.

[0030] In summary, by driving the turntable 6 to rotate via the drive motor 5, the sliding block 2 can be pulled back and forth via the connecting rod 8, thereby driving several insulating bristles 10 to automatically brush back and forth, thus eliminating the need for manual brushing, making operation convenient, and providing stable and uniform brushing force, improving cleaning stability and preventing damage to the circuit board due to excessive force. The back and forth sliding of the sliding block 2 can drive several piston holes 15 to slide relative to the air piston 14, thereby continuously compressing the airflow inside the piston hole 15, which is then introduced into the ventilation partition 17 through the exhaust one-way valve 16. Through the distribution of the ventilation partition 17, the airflow is output from several exhaust micro-holes 12, so that the compressed airflow is pushed from the exhaust micro-holes 12 between several insulating bristles 10 to the sweeping position, thereby directly blowing up the brush contact position while brushing, thus effectively and efficiently cleaning the cleaning position.
