Description

Technical Field

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

[0002] A servo controller is a type of controller used to control servo motors. Its function is similar to that of a frequency converter for ordinary AC motors. It is part of a servo system and is mainly used in high-precision positioning systems.

[0003] For example, CN216313676U discloses a servo controller, including a control board, a power board, and a heat sink. The power board is disposed between the control board and the heat sink. The lower surface of the power board is fixedly connected to the upper surface of the heat sink by at least one solder joint. A plurality of power I / O connectors are disposed in a plurality of first through holes in the control board. The plurality of first through holes are disposed on a first side of the control board. The first end of each power I / O connector is fixedly connected to the upper surface of the power board. A plurality of signal I / O connectors are disposed on a second side of the control board. The first side and the second side are disposed opposite to each other.

[0004] However, in existing technologies, power devices such as power amplifiers and IGBTs in servo controllers draw large currents during operation, generating significant heat. Furthermore, as the power of the servo system increases, the heat generated by these power devices also increases accordingly. This heat buildup inside the controller raises the temperature of the internal electronic components, causing changes in their parameters. The resistance value changes with temperature, affecting the signal accuracy of the control circuit. This, in turn, reduces the accuracy of position and speed control of the servo motor, making it impossible to accurately track command signals. In some high-precision automated production scenarios, this can lead to product quality issues. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where heat accumulation inside the controller causes the temperature of the electronic components inside the servo controller to rise, resulting in changes in their parameters and resistance values, which in turn affects the signal accuracy of the control circuit. Therefore, this invention proposes a servo controller with high heat dissipation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high heat dissipation servo controller, comprising a controller body, wherein a heat dissipation component is fixedly installed on one side of the controller body;

[0007] The heat dissipation assembly includes a positioning plate, a baffle plate, and a movable plate. The positioning plate is fixedly installed on the inner wall of the controller body. The baffle plate is fixedly installed at the edge of the positioning plate and is perpendicular to the positioning plate. The movable plate is fitted between two adjacent baffle plates. One of the baffle plates has an inclined surface at its corner. An electric cylinder is fixedly installed on one side of the positioning plate. A connecting piece is fixedly installed at the corner of the movable plate. One end of the piston rod of the electric cylinder is fixedly connected to a triangular piece, and one end of the connecting piece is movably connected inside the triangular piece.

[0008] Preferably, a strip-shaped hole is provided at the junction of the triangular piece and the connecting piece, and the strip-shaped hole is inclined.

[0009] Preferably, a slider is fixedly connected to one side of the triangular piece, and the slider is in a vertical position.

[0010] Preferably, a guide plate is fixedly installed on one side of the positioning plate, and the guide plate is slidably connected to the slider.

[0011] Preferably, a limiting groove is provided on one side of the positioning plate, and an inclined groove is provided inside the limiting groove.

[0012] Preferably, an arc-shaped groove is fixedly connected to one side of the limiting groove.

[0013] Preferably, a protrusion is fixedly installed at the end of the movable plate, and the protrusion is slidably connected inside the limiting groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a heat dissipation assembly consisting of a baffle plate and a movable plate is provided. During actual use, if a large amount of heat accumulates inside the controller, the electric cylinder can be activated to move the movable plate out from between the two baffle plates, directly exposing the power devices inside the controller, allowing the heat to be quickly dissipated, thereby achieving the purpose of efficient heat dissipation. After heat dissipation is completed, the movable plate can be returned to between the two baffle plates to continue protecting the power devices inside the controller.

[0016] 2. In this utility model, the movement path of the triangular piece is determined by setting a guide plate, so that the movable plate can move up and down, which will not occupy too much space in the controller. The limit groove, tilt groove and arc groove determine the movement path of the movable plate, ensuring that the movable plate can be completely fitted between the two blocking plates, thus ensuring the overall structural stability.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a high heat dissipation servo controller, including a controller body 1, and a heat dissipation component 2 is fixedly installed on one side of the controller body 1;

[0026] The heat dissipation assembly 2 includes a positioning plate 21, a baffle plate 22, and a movable plate 23. The positioning plate 21 is fixedly installed on the inner wall of the controller body 1. The baffle plate 22 is fixedly installed at the edge of the positioning plate 21 and is perpendicular to the positioning plate 21. The movable plate 23 is fitted between two adjacent baffle plates 22. One of the baffle plates 22 has an inclined surface 24 at its corner. An electric cylinder 25 is fixedly installed on one side of the positioning plate 21. A connecting piece 27 is fixedly installed at the corner of the movable plate 23. One end of the piston rod of the electric cylinder 25 is fixedly connected to a triangular piece 29. One end of the connecting piece 27 is movably connected inside the triangular piece 29.

[0027] The specific settings and functions of this embodiment are described below. The heat dissipation component 2 is installed on the side of the controller body 1. Under normal circumstances, the movable plate 23 is spliced ​​between the two baffle plates 22 to form a complete plate to protect the power devices inside the controller body 1. When too much heat accumulates inside the controller body 1, the electric cylinder 25 is activated.

[0028] The electric cylinder 25 drives the connecting plate 27 through the triangular piece 29 to move the movable plate 23 out from between the two blocking plates 22. As the piston rod continues to move, the movable plate 23 will gradually rise, thus completely exposing the space between the two blocking plates 22, allowing the heat inside the controller body 1 to be quickly discharged. The presence of the inclined surface 24 can ensure that the blocking plate 22 does not affect the normal movement of the movable plate 23.

[0029] The positioning plate 21 and the blocking plate 22 are perpendicular to each other and have a right-angle structure, which can ensure the structural stability of the controller body 1. The two blocking plates 22 are arranged symmetrically, one above the other, to ensure that the opening is located in the center of the controller body 1.

[0030] Example 2: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a strip hole 210 is provided at the junction of the triangular piece 29 and the connecting piece 27. The strip hole 210 is in an inclined state. A slider 28 is fixedly connected to one side of the triangular piece 29. The slider 28 is in a vertical state. A guide plate 26 is fixedly installed on one side of the positioning plate 21. The guide plate 26 is slidably connected to the slider 28. A limiting groove 212 is provided on one side of the positioning plate 21. An inclined groove 213 is provided inside the limiting groove 212. An arc groove 214 is fixedly connected to one side of the limiting groove 212. A protrusion 211 is fixedly installed at the end of the movable plate 23. The protrusion 211 is slidably connected inside the limiting groove 212.

[0031] The overall effect of this embodiment is that the presence of the strip hole 210 provides sufficient space for the connecting piece 27 to move. When the movable plate 23 and the blocking plate 22 are spliced ​​together, one protrusion 211 is at the end of the limiting groove 212, and the other protrusion 211 is inside the arc groove 214. When the electric cylinder 25 pushes the movable plate 23, the movable plate 23 rotates with the protrusion 211 below it as the center. The connecting piece 27 moves from the top to the bottom of the triangular piece 29 along the direction of the strip hole 210. At this time, the top protrusion 211 will enter the limiting groove 212 from the arc groove 214, and the bottom protrusion 211 will enter the inclined groove 213. Then, the electric cylinder 25 continues to operate and pushes the movable plate 23 to the top of the controller body 1, thereby exposing the side opening and allowing the heat inside the controller body 1 to be discharged. After the heat is discharged, the electric cylinder 25 pulls the movable plate 23 back between the two blocking plates 22.

[0032] The usage and working principle of this device: Under normal circumstances, the movable plate 23 is spliced ​​between the two blocking plates 22 to form a complete plate to protect the power devices inside the controller body 1. At this time, one protrusion 211 is at the end of the limiting groove 212, and the other protrusion 211 is inside the arc groove 214. When too much heat accumulates inside the controller body 1, the electric cylinder 25 is activated.

[0033] The electric cylinder 25 drives the connecting piece 27 through the triangular piece 29. The connecting piece 27 moves from the top to the bottom of the triangular piece 29 along the direction of the strip hole 210. The top protrusion 211 enters the limiting groove 212 from the arc groove 214. Then, when the electric cylinder 25 continues to push the movable plate 23, the bottom protrusion 211 enters the inclined groove 213. Finally, both protrusions 211 enter the limiting groove 212. As the piston rod continues to move, the movable plate 23 gradually rises, thus completely exposing the space between the two blocking plates 22, allowing the heat inside the controller body 1 to be quickly discharged. After the heat is discharged, the electric cylinder 25 pulls the movable plate 23 back between the two blocking plates 22.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
