Description

Technical Field

[0001] The present invention belongs to the technical field of motion controllers, and specifically discloses a motion controller for a servo motor with an independent heat dissipation function. Background Art

[0003] Currently, the servo motor motion controller generates heat during operation, especially during long-term high-load work, and the heat accumulation may cause the temperature of the internal electronic components of the controller to be too high.

Therefore, the servo motor motion controller is equipped with an active heat dissipation mechanism.

[0004] The active heat dissipation structure of the servo motor motion controller in the prior art is generally air-cooled heat dissipation or liquid-cooled heat dissipation, etc. Among them, liquid-cooled heat dissipation mainly relies on the flow of liquid in the pipeline and uses heat conduction to dissipate heat and cool down the servo motor motion controller.

Detailed implementation manners

[0029] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0031] As Figures 1-9 shown, a motion controller for a servo motor with an autonomous heat dissipation function includes a motion control device 1. An outer housing 2 is provided outside the motion control device 1. The housing 2 is used to provide an installation position and can protect the interior of the motion control device 1. An active cooling mechanism 3 is provided at the bottom of the housing 2. The active cooling mechanism 3 is used to actively dissipate heat for the motion control device 1. A heat dissipation mechanism 4 is provided inside the active cooling mechanism 3. The heat dissipation mechanism 4 is used to assist the active cooling mechanism 3 in dissipating heat. Mounting mechanisms 5 are provided on both sides of the housing 2. The mounting mechanisms 5 are used to mount the housing 2.

[0032] The active cooling mechanism 3 includes a water tank 301 which can provide a liquid storage space. The top of the water tank 301 is fixedly connected to the bottom of the housing 2. Two mounting rings 302 are fixedly connected to the inner side of the water tank 301, which can provide mounting positions. An air-cooling fan 303 is arranged inside the mounting ring 302, which can generate wind and thus achieve air-cooling heat dissipation. A stable mounting housing 304 is fixedly connected inside one of the mounting rings 302, which can provide a stable mounting position. A liquid pumping pump head 305 is fixedly connected inside the stable mounting housing 304. The input shaft of the liquid pumping pump head 305 is fixedly connected to the bottom of the air-cooling fan 303. An inlet water pipe 306 is fixedly connected to the input end of the liquid pumping pump head 305, which can provide conditions for liquid flow. The output end of the liquid pumping pump head 305 is fixedly connected to a cooling and heat dissipation pipe 307, which can make the liquid flow and conduct heat, and thus achieve the heat dissipation effect. A heat-conducting fitting ring 308 is fixedly connected inside the housing 2. A dust-proof plate 309 is fixedly connected to the inner bottom of the mounting ring 302. The cooling and heat dissipation pipe 307 is arranged outside the heat-conducting fitting ring 308. An anti-slip pad is arranged inside the heat-conducting fitting ring 308. One end of the inlet water pipe 306 away from the liquid pumping pump head 305 penetrates through the inner wall of the mounting ring 302. The cooling and heat dissipation pipe 307 penetrates through the bottom of the housing 2. When the air-cooling fan 303 is started, the wind generated after the air-cooling fan 303 rotates can perform air-cooling heat dissipation for the motion control device 1. At the same time, when one of the air-cooling fans 303 rotates, it can drive the input shaft of the liquid pumping pump head 305 to rotate, and thus enable the liquid pumping pump head 305 to have the function of pumping water. The liquid enters the inside of the liquid pumping pump head 305 through the inlet water pipe 306, and enters the inside of the cooling and heat dissipation pipe 307 through the output end of the liquid pumping pump head 305, and dissipates heat for the heat-conducting fitting ring 308. At the same time, through the heat conduction of the heat-conducting fitting ring 308, the inside of the motion control device 1 is cooled, so that liquid cooling and air cooling heat dissipation can be combined.

[0033] The heat dissipation mechanism 4 includes a driving rotating rod 401 which can transmit the power of rotation. The top of the driving rotating rod 401 is fixedly connected to the bottom of another air-cooled cooling fan 303. The bottom of the water tank 301 is rotatably connected to a driving rotating rod 402 which can provide an installation position. The inner bottom end of the water tank 301 is rotatably connected to a driven rotating rod 403 which can also provide an installation position. A first belt is sleeved between the driving rotating rod 402 and the driven rotating rod 403, and a second belt is sleeved between the bottom of the driving rotating rod 401 and the bottom of the driving rotating rod 402. Stirring heat dissipation blades 404 are fixedly connected to the exteriors of the driving rotating rod 402 and the driven rotating rod 403. After the stirring heat dissipation blades 404 rotate, they can stir the liquid inside the water tank 301 and then accelerate the heat dissipation of the liquid inside the water tank 301. The stirring heat dissipation blades 404 are arranged inside the water tank 301. The bottom of the water tank 301 is fixedly connected to a protective housing 405 which has a protective function, preventing the rotation of the second belt from causing injury to the user and also protecting the structure inside the protective housing 405. The driving rotating rod 401, the driving rotating rod 402 and the second belt are all arranged inside the protective housing 405. A stabilizing frame 406 is rotatably connected to the exterior of the driving rotating rod 401, and the outer circumference of the stabilizing frame 406 is fixedly connected to the inner side of the mounting ring 302. A plurality of heat conducting fins 407 are fixedly connected to the exterior of the water tank 301 which can accelerate the heat dissipation of the liquid inside the water tank 301. When the other air-cooled cooling fan 303 rotates, it can drive the driving rotating rod 401 to rotate. The driving rotating rod 401 drives the driving rotating rod 402 to rotate through the second belt. After the driving rotating rod 402 rotates, it drives the driven rotating rod 403 to rotate through the first belt, and then can drive the two stirring heat dissipation blades 404 to rotate. Then, by stirring the liquid inside the water tank 301, the heat dissipation of the liquid inside the water tank 301 is accelerated, and at the same time, the heat dissipation of the water tank 301 can be accelerated again through the heat conducting fins 407, and then a better heat dissipation effect can be achieved.

[0034] The installation mechanism 5 includes an installation clamping bin 501 which provides the conditions for clamping and installation. The top of the installation clamping bin 501 is fixedly connected to the bottom of the motion control device 1. On the side of the installation clamping bin 501 away from the outer shell 2, there is a fixedly connected fixed installation box 502 which provides a space for sliding and installation. Inside the fixed installation box 502, there is a slidably connected sliding limit plate 503 which has a limiting function. On the side of the sliding limit plate 503 close to the outer shell 2, there is a fixedly connected abutting block 504. On the side of the sliding limit plate 503 away from the outer shell 2, there is a fixedly connected pressing sliding plate 505. On both outer sides of the outer shell 2, there are fixedly connected clamping elastic pieces 506. The abutting block 504 can press the clamping elastic pieces 506 to force the clamping elastic pieces 506 to deform, so that the clamping elastic pieces 506 can be drawn out from the inside of the installation clamping bin 501. The pressing sliding plate 505 penetrates through the side of the fixed installation box 502 away from the outer shell 2, and the abutting block 504 penetrates through the side of the installation clamping bin 501 close to the outer shell 2. A protective pad is sleeved outside the abutting block 504. When installing the outer shell 2, first align the clamping elastic piece 506 and push it into the bottom of the installation clamping bin 501. When the clamping elastic piece 506 touches the inner wall of the bottom of the installation clamping bin 501, since the clamping elastic piece 506 is beveled, it will deform towards the outer shell 2 under the extrusion inside the bottom end of the installation clamping bin 501. After the bottom of the clamping elastic piece 506 enters the inside of the installation clamping bin 501, it will reset under the elastic action of the clamping elastic piece 506, and then the bottom of the clamping elastic piece 506 can be used to clamp to the bottom of the installation clamping bin 501 to complete the installation of the outer shell 2. When it is necessary to disassemble the outer shell 2, press the pressing sliding plate 505. The pressing sliding plate 505 drives the sliding limit plate 503 and the abutting block 504 to move towards the outer shell 2, and then the abutting block 504 can be used to press the clamping elastic piece 506 to force the clamping elastic piece 506 to deform. At this time, the outer shell 2 can be pulled out, and at this time, the clamping elastic piece 506 can also leave the inside of the installation clamping bin 501, and then the disassembly of the outer shell 2 can be completed.

[0035] Working principle: When the motion controller actively dissipates heat, start the air-cooling fan 303. After the air-cooling fan 303 rotates, the generated wind can conduct air-cooling for the motion control device 1. At the same time, when one of the air-cooling fans 303 rotates, it can drive the input shaft of the liquid pumping head 305 to rotate, and then the liquid pumping head 305 can have the function of pumping water. The liquid enters the inside of the liquid pumping head 305 through the water inlet pipe 306 and enters the inside of the cooling and heat dissipation pipe 307 through the output end of the liquid pumping head 305 to dissipate heat for the heat conduction bonding ring 308. At the same time, through the heat conduction of the heat conduction bonding ring 308, the inside of the motion control device 1 is cooled, so that liquid cooling and air cooling can be combined for heat dissipation;

[0036] When another air-cooled cooling fan 303 rotates, it can drive the active rotating rod 401 to rotate. The rotation of the active rotating rod 401 drives the driven rotating rod 402 to rotate through the second belt. After the driven rotating rod 402 rotates, it drives the driven rotating rod 403 to rotate through the first belt. Then, it can drive the two stirring heat dissipation blades 404 to rotate. Then, by agitating the liquid inside the water tank 301, the heat dissipation of the liquid inside the water tank 301 is accelerated. At the same time, the heat dissipation of the water tank 301 can be accelerated again through the heat conduction sheet 407, and then a better heat dissipation effect can be achieved.

[0037] When installing the outer shell 2, first push the clamping elastic piece 506 against the bottom of the installation clamping bin 501. When the clamping elastic piece 506 touches the inner wall of the bottom of the installation clamping bin 501, since the clamping elastic piece 506 is a slope, it deforms towards the direction of the outer shell 2 under the extrusion inside the bottom end of the installation clamping bin 501. When the bottom of the clamping elastic piece 506 enters the inside of the installation clamping bin 501, it will reset under the elastic action of the clamping elastic piece 506. Then, the bottom of the clamping elastic piece 506 can be used to clamp at the bottom of the installation clamping bin 501 to complete the installation of the outer shell 2. When it is necessary to disassemble the outer shell 2, press the pressing sliding plate 505. The pressing sliding plate 505 drives the sliding limiting plate 503 and the pushing block 504 to move towards the direction of the outer shell 2. Then, the pushing block 504 can be used to squeeze the clamping elastic piece 506, forcing the clamping elastic piece 506 to deform. At this time, the outer shell 2 can be pulled out. At this time, the clamping elastic piece 506 can also leave the inside of the installation clamping bin 501, and then the disassembly of the outer shell 2 can be completed.
