[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] A multi-axis servo drive power module is arranged, installed and electrically connected with a drive module through the cooperation of a rear end bottom plate component and a connecting seat component.

[0036] like Figure 1-6 As shown together, this embodiment includes a power supply housing 10 which is open on one side and has an inner cavity, a power supply middle frame 20 is installed at the open portion of the power supply housing 10, and also includes a fan assembly 50 and a keyboard assembly 70 which are independently arranged and detachably connected;

[0037] A keyboard assembly mounting slot 11 and a control board mounting slot 12 are formed on the corresponding side of the installation side of the power supply middle frame 20 of the power supply shell 10. A control cover plate 13 is detachably connected to the control board mounting slot 12. The control board mounting slot 12 is provided with a control board 41 at a position corresponding to the inner cavity of the power supply shell 10. The power supply middle frame 20 includes a bottom plate 21 and an isolation plate 22 vertically connected to each other. A power board 30 and a power board 40 are installed on the isolation plate 22. The power board 30 and the power board 40 are electrically connected through a pin header / female header.

[0038] The keyboard assembly 70 is installed in the keyboard assembly installation slot 11. The keyboard assembly 70 includes a lens 71, a keyboard upper shell 72, a keyboard button 73, a keyboard board 74, and a keyboard cover 75 which are arranged in sequence from top to bottom. The lens 71 is formed in a way to avoid the keyboard button 73. The bottom of the keyboard assembly installation slot 11 is provided with a keyboard network port via 14 and a keyboard power strip via 15. Correspondingly, a keyboard network port 35 and a keyboard power strip 36 are respectively provided on the power board 30. When the keyboard assembly 70 is connected to the power board 30, the power strip of the power board 30 is connected and paired to realize electrical connection and communication between the keyboard assembly 70 and the power board 30; when the working environment space is limited and it is inconvenient to operate the keyboard, the keyboard assembly 70 can be disassembled and connected to the keyboard network port 35 of the power board 30 through an ordinary network cable to realize electrical connection and communication, which is very practical.

[0039] A control board socket through hole 16 is provided on the control board installation slot 12, which is convenient for the control board socket to pass through and the installation of the control board 41. The socket on the control board 41 is connected and paired with the power board 30 to achieve electrical connection between the control board 41 and the power board 30. It should be noted that the control board 41 and the power board 30 are both fixed to the grounding terminal 80 by screws to ensure that both are effectively grounded; when the control board 41 is installed, the control cover 13 is covered, and the socket, USB and grounding terminal 80 on the control board 41 are all connected to the control cover 13, which protects the device and facilitates customer wiring; different control boards 41 need to be used when dealing with different application sites. To replace the control board 41, you only need to open the control cover 13, and there is no need to disassemble the entire power module, which is convenient and quick.

[0040] The bottom plate 21 fits into the open part of the power supply housing 10, and a connector through hole 23 is provided on the bottom plate 21; the isolation plate 22 separates the inner cavity of the power supply housing 10 into a heat dissipation duct and a circuit space, and a heat dissipation port 24, a capacitor fixing ring 25, a grounding terminal slot 26, and a fan assembly slot 27 are provided on the isolation plate 22.

[0041] Preferably, the heat dissipation duct of the isolation plate 22 includes a heat sink 60 that blocks the heat dissipation port 24. A brake resistor 42 is installed on the teeth of the heat sink 60, which is beneficial to the heat dissipation of the brake resistor 42 and better utilizes the internal space of the power module. The lead of the brake resistor 42 passes through the protective coil 43 located on the isolation plate 22 and is connected to the power board 30. The protective coil 43 can not only protect the cables, but also seal and isolate the heat dissipation duct of the isolation plate 22 and the circuit space.

[0042] The power board 30 is arranged in the circuit space of the isolation board 22. The power board 30 is provided with a rectifier bridge 31 as the main heating device, a planar transformer 32 with a large heating effect and an electrolytic capacitor 33. The power board 30 is also provided with a connector 34 adapted to the connector via 23 at the edge position near the bottom plate 21. The connector 34 is fitted with the inner side of the bottom plate 21, and the connector 34 is used to electrically connect with the rear end drive module.

[0043] Preferably, a plurality of heating devices are mounted on the power board 40, and the PCB of the power board 40 is an aluminum substrate for facilitating heat conduction. A heat conductive sheet 44 is provided between the aluminum substrate and the planar transformer 32. Specifically, the aluminum substrate is extended to form an area adapted to the size of the magnetic core of the planar transformer 32, and the heat conductive sheet 44 is placed between the area and the planar transformer 32. After installation, the heat conductive sheet 44 is pressed by the aluminum substrate of the power board 40 and the magnetic core of the planar transformer 32, thereby transferring the heat of the planar transformer 32 to the aluminum substrate of the power board 40.

[0044] The aluminum substrates of the rectifier bridge 31 and the power board 40 pass through the heat dissipation port 24 and are tightly attached to the substrate of the radiator 60. In this way, the heat of the rectifier bridge 31, the planar transformer 32, and the power board 40 can be conducted to the radiator 60, thereby improving the heat dissipation efficiency and heat dissipation capacity. The electrolytic capacitor 33 passes through the capacitor fixing ring 25 and its free end passes through the heat dissipation duct. The capacitor fixing ring 25 is also tightly sealed with the power board 40.

[0045] Based on the above structure, it should be noted that all and / or most of the structures of the radiator 60, the brake resistor 42 and the electrolytic capacitor 33 are located in the heat dissipation duct. At the same time, a wind shield is also provided on the isolation plate 22, which is used to separate the radiator 60 and the brake resistor 42 from the electrolytic capacitor 33, so that most of the airflow in the heat dissipation duct passes through the radiator 60 and the brake resistor 42, which account for a large proportion of the heat, and only a small part of the airflow passes through the electrolytic capacitor 33, which generates little heat, thereby improving the overall balance of heat dissipation. There is no air flow on one side of the circuit space, and the internal environment is clean and tidy without dust intrusion, thereby ensuring the stable operation of the power module.

[0046] The ground terminal 80 is installed in the ground terminal slot 26 .

[0047] Since the fan is a wearing part and requires regular maintenance or replacement, the fan assembly 50 of the present embodiment is installed in the fan assembly slot 27 through the power supply housing 10. The fan assembly 50 includes a fan 51 and a fan cover 52 for installing the fan 51, and the fan cover 52 is detachably connected to the fan assembly slot 27; it should be noted that a plug buckle position and a lead slot of the fan 51 are provided on the side of the fan cover 52. After the fan 51 is installed in the fan cover 52, the fan lead is pressed into the lead slot, and then the fan plug is fixed to the plug buckle position, and the whole can be installed in the fan assembly slot 27, which is simple and convenient to operate.

[0048] It should be noted that this embodiment is also applicable to frequency converters, AC converters, and uninterruptible power supplies.

[0049] In this way, the multi-axis servo drive power module provided in this embodiment effectively reduces the overall volume through a reasonable internal structure layout, and has good heat dissipation effect and a high level of protection; at the same time, it adopts an independent keyboard component and fan component design, and the installation, debugging and maintenance are also extremely simple and convenient; by setting the connector at a reasonable position, it can quickly and efficiently make an electrical connection with the rear-end drive module.

[0050] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
