A high-efficiency heat dissipation servo driver housing

Abstract

This utility model relates to the field of servo drive technology, specifically to a high-efficiency heat dissipation servo drive housing; it includes a base and a heat dissipation mechanism, the heat dissipation mechanism including a protective shell base plate, a heat-conducting plate, a locking block, a first fan, an insulating column, a control circuit board body, a protective shell, a connecting block, a limiting block, a second fan, a first filter screen, and auxiliary devices. When the servo drive is working, it will generate a large amount of heat, which can be conducted through the heat-conducting plate. Then, the first fan blows the heat-conducting plate to cool the outer surface, so that the heat can be conducted to the external low-temperature side more quickly, which is conducive to reducing the temperature of the internal working cavity. At the same time, the second fan directly draws the cold air inside the control cabinet and delivers it to the working cavity of the drive. The internal hot air is discharged through the ventilation slot, realizing the rapid discharge of the internal working heat of the servo drive, thereby enabling timely discharge of the internal working heat of the servo drive and improving the control stability of the servo drive.

Description

Technical Field

[0001] This utility model relates to the field of servo drive technology, and in particular to a servo drive housing with high-efficiency heat dissipation. Background Technology

[0002] A servo driver, also known as a servo amplifier, is a precision controller used to control servo motors. Its function is similar to that of a frequency converter for ordinary AC motors. It is an important component of servo control systems and is primarily used in high-precision positioning system control. Currently, it is widely used in CNC system control and industrial robot control.

[0003] The servo drive housing is a structure that isolates and protects the internal electronic components. Existing high-efficiency heat dissipation servo drive housings have the following problems: Current servo drives tend to generate a lot of heat during operation. The accumulation of heat is not easy to dissipate and will affect the operating performance of heat-generating components. Furthermore, the excessive temperature will lead to a sharp reduction in component lifespan and seriously affect control stability. Utility Model Content

[0004] The purpose of this invention is to provide a servo drive housing with high-efficiency heat dissipation, which aims to dissipate the internal working heat of the servo drive in a timely manner, thereby improving the control stability of the servo drive.

[0005] To achieve the above objectives, this utility model provides a high-efficiency heat dissipation servo driver housing, including a base and a heat dissipation mechanism;

[0006] The heat dissipation mechanism includes a protective shell base plate, heat-conducting plates, locking blocks, a first fan, an insulating column, a control circuit board body, a protective outer shell, a connecting block, a limiting block, a second fan, a first filter, and auxiliary devices. Multiple heat-conducting plates are fixed to the protective shell base plate and detachably connected to the base. Multiple locking blocks are detachably connected to the base and positioned on top of the base, abutting against each other. The first fan is mounted on top of the locking blocks. The insulating column is integrally formed with the protective shell base plate. The control circuit board body is detachably connected to the insulating column and electrically connected to the auxiliary devices. The protective outer shell is detachably connected to the protective shell base plate and covers the outside of the control circuit board body, with multiple ventilation slots on its left and right bottom sides. The connecting block is detachably connected to the base and located on the top left rear side of the base. The limiting block is detachably connected to the connecting block and slides against the left end face of the leftmost locking block. The second fan is mounted outside the air inlet on top of the protective outer shell. The first filter is mounted on the top of the second fan's housing. The auxiliary devices are located on the front side of the protective outer shell.

[0007] The auxiliary device includes a data display screen and a connection component. The data display screen is electrically connected to the main body of the control circuit board and is located on the upper left side of the front of the protective housing. The connection component is electrically connected to the main body of the control circuit board and is located on the right side of the protective housing.

[0008] The data display screen has adjustment buttons on its lower side.

[0009] The connecting assembly includes an upper connecting seat and a lower connecting seat. The upper connecting seat is electrically connected to the main body of the control circuit board and is disposed on the upper right side of the protective housing. The lower connecting seat is electrically connected to the main body of the control circuit board and is disposed on the lower side of the upper connecting seat.

The mounting base is detachably connected to the protective housing and is located outside the ventilation slot; the second filter is detachably connected to the mounting base and is located on the mounting base.

[0011] This invention relates to a high-efficiency heat dissipation servo drive housing. During operation, the working cavity, composed of a protective base plate and a protective outer shell, generates a large amount of heat due to the operation of electronic components. This heat is conducted through a heat-conducting plate, and then a first fan blows cool air onto the outer surface of the heat-conducting plate, allowing the heat to be transferred to the lower-temperature external side more quickly, thus reducing the temperature of the internal working cavity. Simultaneously, a second fan directly draws in cool air from inside the electrical control cabinet and delivers it to the working cavity of the drive. The hot air inside is discharged through ventilation slots, achieving rapid heat dissipation from the servo drive and improving the control stability of the servo drive. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a servo driver housing with high-efficiency heat dissipation. Figure 2 This is a schematic diagram of the protective shell base plate 102. This utility model provides a high-efficiency heat dissipation servo drive housing: it includes a base 101 and a heat dissipation mechanism.

This solution enables timely dissipation of internal heat from the servo drive, improving the control stability of the servo drive. It is understood that this solution can improve the control stability of the servo drive.

[0021] In this embodiment, the base 101 can be fixed to the inner wall of the electrical control cabinet with bolts. The electrical control cabinet is equipped with a cooling air conditioner for cooling the entire interior area. The top of the base 101 has a non-through groove from left to right to facilitate the sliding and easy disassembly of the locking block 104.

[0022] The protective shell base plate 102 is fixed with multiple heat-conducting plates 103 and is detachably connected to the base 101. Multiple locking blocks 104 are detachably connected to the base 101 and are disposed on the top of the base 101, abutting against each other. The first fan 105 is mounted on the top of the locking blocks 104. The insulating pillar 106 is integrally formed with the protective shell base plate 102. The control circuit board body 107 is detachably connected to the insulating pillar 106 and electrically connected to the auxiliary device. The protective shell 108 is detachably connected to the protective shell base plate 102 and covers the base. The control circuit board body 107 is attached to the outside, and multiple ventilation slots 109 are provided at the bottom of the left and right sides. The connecting block 110 is detachably connected to the base 101 and is located at the top of the left rear side of the base 101. The limiting block 111 is detachably connected to the connecting block 110 and slides against the left end face of the leftmost locking block 104. The second fan 112 is installed on the outside of the air inlet at the top of the protective shell 108. The first filter screen 113 is installed on the top of the housing of the second fan 112. The auxiliary device is located on the front side of the protective shell 108. Both the protective shell base plate 102 and the protective shell 108 are made of high-strength plastic parts. The protective shell base plate 102 can be connected to the base 101 by bolts, and the protective shell 108 can be connected to the protective shell base plate 102 by bolts. The locking block 104 is a rectangular block with vertical ventilation holes. The first fan 105 is fixed to the top by bolts. The locking block 104 can be directly connected to the first fan 105 at the factory. The control circuit board body 107 is fixed to the insulating post 106 by bolts. The bottom of the left and right sides of the protective shell 108 is provided with multiple ventilation slots 109 for ventilation. The top is provided with an air inlet. The second fan 112 is fixed to the top of the air inlet by bolts. The first fan 105 and the second fan 112 have the same structure and can be connected to the power supply inside the electrical control cabinet. They can also be electrically connected to the power module provided on the control circuit board body 107. The first filter screen 113 is fixed by bolts and is used to filter the cold air entering the interior to reduce dust entering the interior. The auxiliary device works with the control circuit board body 107 to achieve control. The protective housing 108 has gaps between its four inner sidewalls and the edges of the control circuit board body 107, facilitating airflow to the end surface of the heat-conducting plate 103 located within the working cavity of the driver. The rear end of the limiting block 111 is engaged with the slot on the connecting block 110 and secured by a vertically downward-pointing bolt. Multiple heat-conducting plates 103 are arranged in a line at intervals.

[0023] Secondly, the data display screen 114 is electrically connected to the control circuit board body 107 and is located on the upper left side of the protective housing 108; the connecting component is electrically connected to the control circuit board body 107 and is located on the right side of the protective housing 108. The data display screen 114 is used to display corresponding data and status during operation, and can also display corresponding alarm codes in case of abnormalities, so that maintenance personnel can quickly understand the situation and carry out maintenance. For example, the control circuit board body 107 is equipped with a temperature monitoring module. When the internal working chamber temperature is too high, the data display screen 114 will display an over-temperature alarm code. The connecting component is used to connect and cooperate with the servo motor and CNC system.

[0024] Then, an adjustment button 115 is provided on the lower side of the data display screen 114. The adjustment button 115 is used for debugging or parameter setting of the servo drive.

[0025] Finally, the upper connector 116 is electrically connected to the control circuit board body 107 and is located on the upper right side of the protective housing 108; the lower connector 117 is electrically connected to the control circuit board body 107 and is located below the upper connector 116.

Simultaneously, aviation connectors for the driver's main power input and servo motor power connection are provided on the right sides of the lower connector 117 and the upper connector 116 for engagement. Threaded posts are symmetrically arranged on both sides of the upper connector 116 and the lower connector 117 in the vertical direction for locking the external connectors after insertion.

[0026] When using this invention to promptly dissipate the internal heat of the servo drive and improve its control stability, the working cavity formed by the protective shell base plate 102 and the protective shell 108 generates a large amount of heat due to the operation of electronic components on the control circuit board body 107. This heat is first conducted through the heat-conducting sheet 103, and then cooled by multiple first fans 105 blowing on the outer surface of the heat-conducting sheet 103, allowing the heat to be transferred more quickly to the lower-temperature external side, thus reducing the internal working cavity temperature. Simultaneously, the second fan 112 directly draws and delivers cool air from inside the control cabinet to the working cavity of the drive, while the hot air is discharged through the ventilation slot 109. This rapid dissipation of internal heat from the servo drive, with the discharged hot air inside the control cabinet equipped with a cooling air conditioner, further facilitates the timely dissipation of internal heat from the servo drive and improves its control stability.

[0028] like Figure 3 and Figure 4 As shown, where Figure 3 This is a schematic diagram of the overall structure of a servo driver housing with high-efficiency heat dissipation. Figure 4 This is a structural schematic diagram of the fixed base 201. Based on the first embodiment, this utility model provides a servo driver housing with high-efficiency heat dissipation. The servo driver housing with high-efficiency heat dissipation also includes a protective mechanism, which includes the fixed base 201 and a second filter 202.

[0029] The mounting base 201 is detachably connected to the protective housing 108 and is located outside the ventilation slot 109; the second filter 202 is detachably connected to the mounting base 201 and is located on the mounting base 201.

The second filter 202 has an L-shaped structure and is slidably disposed on the mounting base 201 during installation, fitting against the surface of the protective housing 108, and then fixed with bolts.

[0030] In this embodiment, by providing the second filter 202 on the outside of the ventilation slot 109, it is beneficial to reduce the amount of dust entering the interior when the second fan 112 is damaged and not rotating.
