Description

Technical Field

[0001] This utility model relates to the field of servo driver technology, specifically a servo driver with a through-type heat dissipation structure. Background Technology

[0002] A servo drive, also known as a servo controller or servo amplifier, is a 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 primarily used in high-precision positioning systems. Generally, it controls the servo motor through three methods: position, speed, and torque, achieving high-precision positioning of the transmission system. It is a high-end product in transmission technology.

[0003] Some existing servo drives generate significant heat during operation, thus requiring strong heat dissipation capabilities. However, existing servo drives typically achieve efficient heat dissipation through a dual structure of fans and heat sink fins. However, the heat sink fins rely on natural airflow to dissipate heat, resulting in low heat dissipation efficiency and poor cooling performance, impacting the servo drive's operating efficiency. Prolonged use with high-power drive motors can damage the servo drive and even cause fires, making it impractical. Therefore, we propose a servo drive with a through-type heat dissipation structure to address these issues. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6This utility model provides a technical solution: a servo driver with a through-type heat dissipation structure, including a servo driver body 1. Both sides of the servo driver body 1 have internally connected first mounting slots 2. The inner wall of the first mounting slot 2 has a through groove 4, and heat dissipation fins 3 are disposed inside the through groove 4. Two second mounting slots 5 are formed on the upper surface of the servo driver body 1, and cooling fans 6 are disposed inside the second mounting slots 5. The rear cooling fan 6 is connected to the interior of the servo driver body 1. The main body 1 has an internal cavity 7, and the front second mounting slot 5 is connected to the cavity 7. The servo driver main body 1 has an internal ventilation chamber 8, which is connected to the cavity 7. The inner wall of the through slot 4 has a first ventilation groove 9, which is connected to the ventilation chamber 8. The inner wall of the first mounting slot 2 has a second ventilation groove 10, which is connected to the ventilation chamber 8. The inner walls of the upper and lower sides of the first mounting slot 2 have slots 11, and the inner wall of the upper slot 11 has a connecting groove 12. The device is internally equipped with a drive assembly, and the servo drive body 1 is internally equipped with a baffle 13. By activating two cooling fans 6, the rear cooling fan 6 will draw away the heat inside the servo drive body 1, while the heat dissipation fins 3 will conduct the heat inside the servo drive body 1. At this time, the rear cooling fan 6 and the heat dissipation fins 3 will simultaneously exhaust the heat inside the servo drive body 1. The front cooling fan 6 will cause air to pass through the cavity 7, the ventilation chamber 8, the first ventilation slot 9 and the second ventilation slot 10 to exhaust the heat on the surface of the heat dissipation fins 3. When the heat dissipation fins 3 need to be replaced, the baffle 13 can block the through slot 4 when the heat dissipation fins 3 are removed by the drive assembly. The above structure further improves the heat dissipation effect of the device and ensures the heat dissipation efficiency of the servo drive body 1. First, the rear cooling fan 6 and the heat dissipation fins 3 work together to dissipate heat inside the servo drive body 1, and then the airflow generated by the front cooling fan 6 dissipates heat from the heat dissipation fins 3. It has high practicality and high heat dissipation efficiency.

[0025] Furthermore, both ends of the heat dissipation fins 3 are fixedly connected to connecting plates 14. The upper surface of the connecting plates 14 is provided with a first sliding groove 15. A locking block 16 is slidably connected inside the first sliding groove 15. The locking block 16 is compatible with the locking groove 11. The surface of the connecting plates 14 is provided with a second sliding groove 17. An operating plate 18 is slidably connected inside the second sliding groove 17. The operating plate 18 is fixedly connected to the locking block 16. A first spring 19 is fixedly connected between the locking block 16 and the inner wall of the first sliding groove 15. When the operator needs to disassemble the heat dissipation fins 3, by bringing the operating plates 18 on the upper and lower sides closer together, the movement of the operating plate 18 can drive the locking block 16 to slide inside the first sliding groove 15, and the first spring 19 will deform, ultimately realizing that the locking block 16 is disengaged from the inside of the locking groove 11, thereby realizing the disassembly of the heat dissipation fins 3. The above structure greatly improves the efficiency of the operator in disassembling and assembling the heat dissipation fins 3. The operation steps are very simple, realizing the rapid disassembly and assembly of the heat dissipation fins 3, thereby further improving the overall practicality of the device.

[0026] Furthermore, the drive assembly includes a trapezoidal block 20, which is slidably connected inside the communicating groove 12. A sliding through groove 21 is provided on the inner wall of the servo drive body 1, and the communicating groove 12 is connected to the interior of the servo drive body 1 through the sliding through groove 21. A connecting rod 23 is fixedly connected to the surface of the trapezoidal block 20, and the connecting rod 23 is slidably connected inside the sliding through groove 21 and extends into the interior of the servo drive body 1. A fixing plate 22 is fixedly connected to the upper end of the baffle 13, and the connecting rod 23 and the fixing plate 22 are fixedly connected. A second spring 24 is fixedly connected between the trapezoidal block 20 and the inner wall of the communicating groove 12. When the operator installs the heat dissipation fins 3, during the process of the locking block 16 sliding into the locking slot 11, the locking block 16 will first contact the inclined surface of the trapezoidal block 20, thereby pushing the trapezoidal block 20 to slide inside the communicating groove 12. At this time, the second... Spring 24 deforms, and when trapezoidal block 20 moves, it drives connecting rod 23 to slide inside sliding groove 21. The movement of connecting rod 23 drives fixed plate 22 to move, and the movement of fixed plate 22 drives baffle 13 to move. Ultimately, when heat dissipation fins 3 are installed, baffle 13 does not block groove 4. After heat dissipation fins 3 are removed, the elastic force of the second spring 24 drives baffle 13 to move, thereby blocking groove 4. Through the cooperation of drive component and baffle 13, external dust and foreign objects are prevented from entering the servo drive body 1 through groove 4 after heat dissipation fins 3 are removed, thus ensuring the safety of servo drive body 1 and its normal use. At the same time, it improves the overall protection of the device. It is highly practical and safe, and no additional operation is required from personnel.

[0027] In the above embodiment, both the baffle 13 and the fixing plate 22 are in contact with the inner wall of the servo driver body 1.

[0028] Working principle:

[0029] When the servo driver with a through-type heat dissipation structure is in use, by activating the two cooling fans 6, the rear cooling fan 6 will draw away the heat inside the servo driver body 1, and at the same time the heat dissipation fins 3 will conduct the heat inside the servo driver body 1. At this time, the rear cooling fan 6 and the heat dissipation fins 3 will simultaneously exhaust the heat inside the servo driver body 1. The front cooling fan 6 will cause the air to pass through the cavity 7, the ventilation chamber 8, the first ventilation slot 9 and the second ventilation slot 10 to exhaust the heat on the surface of the heat dissipation fins 3. When the heat dissipation fins 3 need to be replaced, the baffle 13 can be used to block the through slot 4 when the heat dissipation fins 3 are removed by setting the drive component.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
