TECHNICAL FIELD

[0001] The present application relates to the technical field of servo driver, in particular to a servo driver conduction heat dissipation structure. BACKGROUND

[0002] As a core control component in the field of industrial automation, the servo driver is widely used. The internal power module of the servo driver will generate a large amount of heat during high-frequency switching operation, and needs to be assisted by a conduction heat dissipation structure for heat dissipation.

[0003] The conduction heat dissipation structure of the servo driver in the prior art is mostly through a metal heat conduction plate to transfer the heat generated by the internal components to the heat dissipation fins, so as to dissipate the heat to the environment. However, with the increase of use time, dust and other impurities are easy to adhere to the fin gap, and long-term accumulation will cause the effective heat dissipation area of the fin to decrease, the airflow circulation resistance to increase, and the heat dissipation efficiency to greatly decrease, thereby affecting the heat dissipation effect. Therefore, we propose a servo driver conduction heat dissipation structure. SUMMARY

[0004] In view of the shortcomings of the prior art, the present application provides a servo driver conduction heat dissipation structure, which solves the problem that the servo driver conduction heat dissipation structure mostly transfers the heat generated by the internal components to the heat dissipation fins through a metal heat conduction plate, so as to dissipate the heat to the environment. However, with the increase of use time, dust and other impurities are easy to adhere to the fin gap, and long-term accumulation will cause the effective heat dissipation area of the fin to decrease, the airflow circulation resistance to increase, and the heat dissipation efficiency to greatly decrease, thereby affecting the heat dissipation effect.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: A servo driver conduction heat dissipation structure, comprising a servo driver body, a first heat conduction plate fixedly connected to the outer side of the servo driver body, a shell fixedly connected to the outside of the servo driver body, a through hole formed on the side of the shell close to the first heat conduction plate, a second heat conduction plate fixedly installed in the through hole, the second heat conduction plate abutting against the first heat conduction plate, a plurality of heat dissipation fins fixedly connected in a straight line array on the side of the second heat conduction plate away from the first heat conduction plate, and a cleaning mechanism arranged in the shell for cleaning the heat dissipation fins.

A connecting seat is fixedly connected to the outside of the connecting shaft. A cleaning frame is installed on the outside of the connecting seat by bolts.

[0007] The technical effect of adopting the above-mentioned further solution is that the movement of the lifting seat can be limited by the setting of the limiting rod, so that the lifting seat slides along the limiting rod to prevent deviation. The cleaning rack is rotated by the connecting shaft and the connecting seat, which facilitates the storage or unfolding of the cleaning rack. The movement of the cleaning rack can drive the bristles on its outer side to clean the heat dissipation fins.

[0008] In a preferred embodiment, the inner wall of the housing is fixedly connected with a plurality of fixed rods in a linear array. One end of each fixed rod is fixedly connected to a fixed frame. The fixed frame has a vertical groove and an oblique groove inside, which are connected to each other. One end of the connecting shaft passes through the lifting seat and is fixedly connected to a connecting ring. A convex post is fixedly connected to the outside of the connecting ring. The convex post slides in contact with the vertical groove and the oblique groove respectively.

[0009] The technical effect of adopting the above-mentioned further solution is that the vertical groove and the oblique groove can be used in conjunction with the convex column during the movement of the lifting seat, thereby driving the connecting shaft to rotate, which facilitates the unfolding and use or storage of the cleaning rack.

[0010] In a preferred embodiment, the housing is provided with a lifting assembly for driving the lifting seat to move up and down. The lifting assembly includes a rotating shaft rotatably connected to the inner wall of the housing. One end of the rotating shaft is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a connecting column. The lifting seat is provided with a connecting groove that cooperates with the connecting column. A servo motor is fixedly connected to the outside of the housing, and the output end of the servo motor is fixedly connected to the rotating shaft.

[0011] The technical effect of adopting the above-mentioned further solution is that the servo motor drives the connecting rod to rotate through the rotating shaft, and the connecting rod drives the connecting column to rotate, so that the connecting column and the connecting groove can be used together, thereby squeezing and driving the lifting seat to move when the connecting column rotates.

[0012] In a preferred embodiment, a top plate is bolted to the top of the housing, and multiple air outlets are arranged in a linear array on the top of the top plate. A filter screen is bolted to the outside of the ventilation frame.

[0013] The technical effect of adopting the above-mentioned further solution is that the setting of the air outlet can accelerate the airflow inside the casing, thereby assisting in heat dissipation.

[0014] In a preferred embodiment, the fixing component includes a U-shaped support frame fixedly connected to the bottom of the housing. An adjustment block is slidably connected to the inner wall of the support frame. A support rod is fixedly connected to the outer side of the adjustment block. Multiple inserts are fixedly connected to the top of the support rod in a linear array. The inserts extend into the housing. Multiple slots that cooperate with the inserts are provided in a linear array at the bottom of the collection box.

[0015] The technical effect of adopting the above-mentioned further solution is that the adjustment block drives the support rod to move, and the support rod drives the insertion block to move into or out of the slot, which facilitates locking or unlocking the collection box for removal.

[0016] In a preferred embodiment, the inner wall of the support frame is symmetrically fixedly connected with sliding rods, the adjusting block is slidably connected to the sliding rods, the inside of the support frame is rotatably connected to a lead screw via a bearing, the adjusting block is threadedly connected to the lead screw, the bottom of the support frame is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to the lead screw.

[0017] The technical effect of adopting the above-mentioned further solution is that the drive motor drives the lead screw to rotate, thereby causing the adjusting block to slide. The movement of the adjusting block can be limited by the setting of the slide rod to prevent deviation.

[0018] In a preferred embodiment, the sealing assembly includes a fixed plate fixedly connected to the inner wall of the ventilation frame, a connecting rod fixedly connected to the side of the adjusting block away from the support rod, a lifting plate fixedly connected to one end of the connecting rod, a sliding plate fixedly connected to the top of the lifting plate, and multiple sets of ventilation slots arranged in a rectangular array inside both the fixed plate and the sliding plate.

[0019] The technical effect of adopting the above-mentioned further solution is that the adjusting block drives the sliding plate to move through the connecting rod and the lifting plate, so that the sliding plate and the ventilation groove of the lifting plate are aligned or deviated, which facilitates the sealing of the interior of the ventilation frame.

[0020] This invention provides a conductive heat dissipation structure for a servo driver. Compared with the prior art, it has the following advantages: 1. The servo driver's conductive heat dissipation structure achieves the function of conductive heat dissipation through the arrangement of a first heat-conducting plate, a second heat-conducting plate, heat dissipation fins and a fan. It can accelerate the air circulation inside the housing, form a directional airflow channel through the air outlet, realize the rapid dissipation of heat, effectively reduce the operating temperature of the servo driver body, and avoid performance degradation or failure due to overheating.

[0021] 2. The servo drive conduction heat dissipation structure, through the setting of lifting components and cleaning mechanism, can automatically clean the heat dissipation fins. When the lifting seat moves down, the convex column slides along the inclined groove of the fixed frame, driving the cleaning frame to rotate clockwise to the unfolded state. The gaps between the heat dissipation fins are thoroughly cleaned by a soft anti-static brush to avoid dust accumulation affecting the heat dissipation effect. After cleaning, the cleaning frame moves up with the lifting seat and automatically retracts into a vertical state, without obstructing the airflow channel, ensuring the heat dissipation effect.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 13 The present invention provides a technical solution: A servo driver heat dissipation structure includes a servo driver body 1. A first heat-conducting plate 11 is fixedly connected to the outer side of the servo driver body 1 to transfer the heat generated by the internal components of the servo driver body 1 during operation. A housing 2 is fixedly connected to the outside of the servo driver body 1. A through-hole is opened on the side of the housing 2 near the first heat-conducting plate 11. A second heat-conducting plate 25 is fixedly installed in the through-hole and abuts against the first heat-conducting plate 11. Multiple heat dissipation fins 24 are fixedly connected in a linear array on the side of the second heat-conducting plate 25 away from the first heat-conducting plate 11. A cleaning mechanism is provided inside the housing 2 for cleaning the heat dissipation fins 24. The arrangement of the first heat-conducting plate 11, the second heat-conducting plate 25 and the heat dissipation fins 24 can transfer the heat generated by the internal components of the servo driver body 1 during operation, thereby dissipating the heat into the environment. The cleaning mechanism can periodically clean the heat dissipation fins 24. A collection box 22 is slidably connected to the bottom of the inner cavity of the housing 2. One side of the collection box 22 extends to the outside of the housing 2. A fixing component for locking the collection box 22 is provided at the bottom of the housing 2. A ventilation frame 3 is fixedly connected to the outside of the housing 2. The ventilation frame 3 is connected to the housing 2. A fan 31 is installed on the inner wall of the ventilation frame 3 for blowing air into the inside of the housing 2 to accelerate the airflow. A sealing component for sealing the ventilation frame 3 is provided inside the ventilation frame 3.

[0026] In this solution, the dust generated during the cleaning of the heat dissipation fins 24 can be collected and treated by the collection box 22, the collection box 22 can be quickly installed and fixed by the fixing component, the ventilation frame 3 can be blocked by the sealing component when cleaning the heat dissipation fins 24, and the fan 31 can accelerate the airflow inside the housing 2, thereby achieving the effect of heat dissipation.

[0027] like Figures 3 to 9 As shown: In this solution, the cleaning mechanism includes limiting rods 26 symmetrically fixedly connected to the inner cavity of the housing 2. A lifting seat 41 is slidably sleeved on the outside of the limiting rods 26. The lifting seat 41 is open on both the side near the second heat-conducting plate 25 and at the bottom. A connecting shaft 74 is rotatably connected to the inner cavity of the lifting seat 41. A connecting base 71 is fixedly connected to the outside of the connecting shaft 74. A cleaning frame 7 is bolted to the outside of the connecting base 71. The cleaning frame 7 is comb-shaped, and bristles are provided in the groove on the comb-shaped side of the cleaning frame 7. Multiple fixing rods 61 are fixedly connected in a linear array to the inner wall of the housing 2. A fixing frame 6 is fixedly connected to one end of each fixing rod 61. The fixing frame 6 has vertical grooves 62 and oblique grooves 63 inside. The vertical groove 62 and the inclined groove 63 are connected. One end of the connecting shaft 74 passes through the lifting seat 41 and is fixedly connected to the connecting ring 73. The outer side of the connecting ring 73 is fixedly connected to the convex column 72, which slides in contact with the vertical groove 62 and the inclined groove 63 respectively. The inside of the housing 2 is provided with a lifting assembly for driving the lifting seat 41 to move up and down. The lifting assembly includes a rotating shaft 42 rotatably connected to the inner wall of the housing 2. One end of the rotating shaft 42 is fixedly connected to the connecting rod 44, and one end of the connecting rod 44 is fixedly connected to the connecting column 45. The inside of the lifting seat 41 is provided with a connecting groove 43 that cooperates with the connecting column 45 for driving the lifting seat 41 to move up and down. The outside of the housing 2 is fixedly connected to the servo motor 4, and the output end of the servo motor 4 is fixedly connected to the rotating shaft 42.

[0028] In this design, initially, the convex column 72 is located at the top of the inclined groove 63, and the cleaning rack 7 is in the retracted state. The servo motor 4 is activated, and it drives the connecting rod 44 to rotate closer to the fixed frame 6 via the rotating shaft 42. The connecting rod 44 drives the connecting column 45 to rotate, allowing the connecting column 45 to engage with the connecting groove 43. As the connecting column 45 rotates, it presses against and drives the lifting seat 41 downwards. Two sets of limiting rods 26 limit the movement of the lifting seat 41 to prevent deviation. During the downward movement of the lifting seat 41, the inclined groove 63 presses against and drives the convex column 72 to rotate clockwise around the connecting shaft 74. The convex column 72 is connected to the connecting ring 73 and the connecting shaft 74. 4 drives the connecting seat 71 to rotate, thereby driving the cleaning frame 7 to rotate clockwise. When the convex column 72 moves to the vertical groove 62, the cleaning frame 7 is in the unfolded state. At this time, the downward movement of the cleaning frame 7 can drive the bristles on its outer side to clean the heat dissipation fins 24. The bristles are made of soft anti-static material. The anti-static material is added to the nylon bristles to avoid static electricity generated by friction during cleaning and prevent static electricity from adsorbing dust residue. When the lifting seat 41 continues to move downward, the convex column 72 will move along the vertical groove 62. The connecting shaft 74 will not rotate. When it reaches the bottom, the cleaning work of the heat dissipation fins 24 is completed. The dust generated during cleaning will fall into the collection box 22 for collection. After cleaning is completed, the servo motor 4 is started. The servo motor 4 drives the connecting rod 44 to rotate away from the fixed frame 6 via the rotating shaft 42. The connecting rod 44 drives the connecting column 45 to rotate, so that the connecting column 45 and the connecting groove 43 cooperate. When the connecting column 45 rotates, it squeezes and drives the lifting seat 41 to move upward. When the lifting seat 41 moves upward, the convex column 72 first slides along the vertical groove 62. When the convex column 72 enters the inclined groove 63, the inclined groove 63 squeezes and drives the convex column 72 to rotate counterclockwise around the connecting shaft 74. The convex column 72 drives the connecting seat 71 to rotate through the connecting ring 73 and the connecting shaft 74, thereby driving the cleaning frame 7 to rotate counterclockwise. When it reaches the top of the inclined groove 63, the cleaning frame 7 rotates to a vertical position for storage, without obstructing the flow of gas.

[0029] like Figure 2 , Figure 11 and Figure 13As shown: In this scheme, a top plate 21 is bolted to the top of the housing 2. Multiple air outlets 23 are arranged in a linear array on the top of the top plate 21. A filter screen 32 is bolted to the outside of the ventilation frame 3. The fixing components include a U-shaped support frame 5 fixedly connected to the bottom of the housing 2. An adjusting block 57 is slidably connected to the inner wall of the support frame 5. A support rod 51 is fixedly connected to the outer side of the adjusting block 57. Multiple inserts 54 are fixedly connected in a linear array on the top of the support rod 51. The inserts 54 extend into the housing 2. Multiple slots 27 that cooperate with the inserts 54 are arranged in a linear array on the bottom of the collection box 22. A sliding rod 56 is symmetrically fixedly connected to the inner wall of the support frame 5. The adjusting block 57 is slidably connected to the sliding rod 56. A lead screw 55 is rotatably connected to the inside of the support frame 5 through a bearing. The adjusting block 57 is threadedly connected to the lead screw 55. A drive motor 53 is fixedly connected to the bottom of the support frame 5. The output end of the drive motor 53 is fixedly connected to the lead screw 55.

[0030] In this design, the drive motor 53 drives the lead screw 55 to rotate, thereby causing the adjusting block 57 to move up or down. The adjusting block 57 drives the insert block 54 to move up or down via the support rod 51, so that the insert block 54 moves into or out of the slot 27, which facilitates locking or unlocking the position of the collection box 22. Locking the position of the collection box 22 can prevent the collection box 22 from becoming loose during the operation of the equipment, which would cause some air to blow out from the gaps in the collection box 22 and affect the heat dissipation effect of the heat sink fins 24.

[0031] like Figure 12 and Figure 13 As shown: In this solution, the sealing component includes a fixed plate 33 fixedly connected to the inner wall of the ventilation frame 3, a connecting rod 52 fixedly connected to the side of the adjusting block 57 away from the support rod 51, a lifting plate 35 fixedly connected to one end of the connecting rod 52, a sliding plate 34 fixedly connected to the top of the lifting plate 35, the sliding plate 34 slidably connected to the ventilation frame 3, and the sliding plate 34 is in close contact with the fixed plate 33. The interior of the fixed plate 33 and the interior of the sliding plate 34 are both arranged in a rectangular array with multiple sets of ventilation slots.

[0032] In this scheme, initially, the ventilation slots of the sliding plate 34 and the fixed plate 33 are aligned, allowing ventilation. When cleaning the heat dissipation fins 24, the fan 31 is turned off to stop ventilation. The adjusting block 57 moves the sliding plate 34 downward through the connecting rod 52 and the lifting plate 35, causing the ventilation slots of the sliding plate 34 and the lifting plate 35 to be misaligned, thereby sealing the ventilation frame 3 and preventing dust from entering the ventilation frame 3 during cleaning of the heat dissipation fins 24. After cleaning, the adjusting block 57 moves the sliding plate 34 upward through the connecting rod 52 and the lifting plate 35, aligning the ventilation slots of the sliding plate 34 and the fixed plate 33, allowing ventilation.

[0033] Working principle: When in use, the device can be powered by an external power supply. During normal use, the cleaning rack 7 is in a retracted state and will not obstruct the airflow inside the housing 2. The first heat-conducting plate 11, the second heat-conducting plate 25 and the heat dissipation fins 24 can transfer the heat generated by the internal components of the servo driver body 1 during operation, thereby dissipating the heat into the environment. When the fan 31 is turned on, the ventilation slots of the fixed plate 33 and the sliding plate 34 are aligned during normal operation, and air can circulate. The fan 31 can blow air into the housing 2 through the ventilation slots and blow it out through the air outlet 23. The airflow can carry away the heat of the heat dissipation fins 24, thereby playing the role of heat conduction and heat dissipation. When it is necessary to clean the dust and other debris attached to the heat sink fins 24, turn off the fan 31 to stop ventilation and prevent the dust blown by the fan 31 from spreading everywhere. Start the drive motor 53, which drives the lead screw 55 to rotate, thereby moving the adjusting block 57 downward. The adjusting block 57 moves the sliding plate 34 downward through the connecting rod 52 and the lifting plate 35, so that the ventilation groove of the sliding plate 34 is misaligned with the ventilation groove of the lifting plate 35, thereby blocking the ventilation frame 3 and preventing dust from entering the ventilation frame 3 when cleaning the heat sink fins 24. At the same time, the adjusting block 57 moves the insert block 54 downward through the support rod 51, so that the insert block 54 is disengaged from the slot 27, thereby releasing the locking state of the collection box 22, making it easy to remove the collection box 22 after cleaning. Initially, the convex column 72 is located at the top of the inclined groove 63, and the cleaning rack 7 is in the retracted state. The servo motor 4 is activated, and the servo motor 4 drives the connecting rod 44 to rotate closer to the fixed frame 6 via the rotating shaft 42. The connecting rod 44 drives the connecting column 45 to rotate, causing the connecting column 45 to engage with the connecting groove 43. As the connecting column 45 rotates, it presses against and drives the lifting seat 41 downwards. Two sets of limit rods 26 limit the movement of the lifting seat 41 to prevent deviation. During the downward movement of the lifting seat 41, the inclined groove 63 presses against and drives the convex column 72 to move downwards. The connecting shaft 74 rotates clockwise, and the convex column 72 drives the connecting seat 71 to rotate through the connecting ring 73 and the connecting shaft 74, thereby driving the cleaning frame 7 to rotate clockwise. When the convex column 72 moves to the vertical groove 62, the cleaning frame 7 is in the unfolded state. At this time, the cleaning frame 7 can clean the heat dissipation fins 24 by moving downward. When it continues to move downward, the convex column 72 will move along the vertical groove 62, and the connecting shaft 74 will not rotate. When it reaches the bottom, the cleaning work of the heat dissipation fins 24 is completed, and the dust generated during cleaning will fall into the collection box 22 for collection. After cleaning is completed, the servo motor 4 is started. The servo motor 4 drives the connecting rod 44 to rotate away from the fixed frame 6 via the rotating shaft 42. The connecting rod 44 drives the connecting column 45 to rotate, so that the connecting column 45 and the connecting groove 43 cooperate. When the connecting column 45 rotates, it squeezes and drives the lifting seat 41 to move upward. When the lifting seat 41 moves upward, the convex column 72 first slides along the vertical groove 62. When it enters the inclined groove 63, the inclined groove 63 squeezes and drives the convex column 72 to rotate counterclockwise around the connecting shaft 74. The convex column 72 drives the connecting seat 71 to rotate through the connecting ring 73 and the connecting shaft 74, thereby driving the cleaning frame 7 to rotate counterclockwise. When it reaches the top of the inclined groove 63, the cleaning frame 7 rotates to a vertical position for storage, without obstructing the flow of gas.
