[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] In one embodiment, such as Figure 1 As shown, a modular servo driver power unit module is provided, which includes: a mounting bracket (10), a power board (20), a heat sink (30), a power input port (203), a control input port (202), a control output port (201), and multiple IPM modules (204).

[0028] The power board (20) integrates multiple IPM modules (204) in its middle area, and integrates a power input port (203), a control input port (202), and a control output port (201) in its edge area. The power input port (203) is used to receive external power. The control input port (202) is used to acquire control signals sent by external devices. The control output port (201) is used to send drive signals to external motors.

[0029] The power board (20) is fixedly mounted on the mounting bracket (10), and the heat sink (30) is connected to the middle area of ​​the power board (20) to make close contact with the plurality of IPM modules (204).

[0030] The heat sink (30) only covers the area where multiple IPM modules (204) are located. The power input port (203), control input port (202) and control output port (201) are located on the edge of the power board (20). The heat sink (30) does not cover the area where the power input port (203), control input port (202) and control output port are located, thereby allowing the power input port (203), control input port (202) and control output port to be connected to external devices.

[0031] The power input port (203) is connected to the power input circuit on the power board (20). Thus, the power input port (203) receives external power to provide the necessary electrical energy to the IPM module (204) and other circuits on the power board (20). The control output port (205) is connected to the feedback circuit on the power board (20) so that the feedback circuit of the power board (20) outputs processed status information, feedback signals, or control signals to external devices for outputting control signals. The control input port (202) is connected to the control circuit on the power board (20) to receive external control signals, which are typically from an external controller (such as a PLC, microcontroller, or other host computer), for controlling the operating state of the power board (20).

[0032] In the aforementioned modular servo driver power unit module, the power board (20) integrates multiple IPM modules (204), a power input port (203), a control input port (202), and a control output port (201). At the same time, the heat sink (30) is fixed in the area where the fixed IPM module (204) is located on the power board (20), and the power board (20) is fixed on the mounting bracket (10). Thus, the heat sink (30), power board (20), IPM module (204), power input port (203), control input port (202), and control output port (201) are individually packaged and installed, forming a whole with high structural strength. Therefore, the power unit module can be individually repaired and customized, has strong reusability, and reduces design and maintenance costs.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the servo driver power unit module also includes: a fixing device; the fixing device includes multiple press-fit studs (104), multiple hexagonal isolation posts (50), and fixing screws (60);

[0034] The power board (20) includes a plurality of first through holes, and the heat sink includes a plurality of second mounting holes;

[0035] The mounting bracket (10) is fixedly provided with a plurality of first press-fit studs (104) and second press-fit studs (103). One end of the hexagonal isolation post (50) passes through a plurality of first through holes on the power board (20) and is installed on the first press-fit studs (104) of the mounting bracket (10). A portion of the fixing screws (60) passing through a plurality of second mounting holes on the radiator (30) is installed on the other end of the hexagonal isolation post (50) to fix the power board (20).

[0036] The second press-fit stud (103) passes through a plurality of first through holes on the power plate (20), and another portion of the fixing screws (60) passes through a plurality of second mounting holes on the radiator (30) and are mounted on the second press-fit stud (103) to fix the radiator (30).

[0037] In one embodiment, the IPM module (204) includes a third through hole; the surface of the heat sink (30) is provided with a plurality of threaded holes (301), and a fixing screw (60) passes through the third through hole and is installed in the threaded hole (301) of the heat sink to realize the fixed connection between the IPM module (204) and the heat sink (30).

[0038] In one embodiment, the mounting bracket (10) further includes a fixing hole (101) and a fixing threaded hole (102) for fixing the servo driver power unit module.

[0039] In one embodiment, the edge of the power board (20) is provided with a limiting member (40), and the limiting member (40) is provided with a countersunk hole; the countersunk hole can be used in conjunction with an external positioning pin device.

[0040] In this embodiment, the limiting member (40) is installed on the power board (20) and has a countersunk hole, which can be used in conjunction with an external positioning pin device to ensure the uniqueness of the module assembly position.

[0041] In one embodiment, the radiator (30) includes multiple fins. This increases the surface area of ​​the radiator, thereby improving heat dissipation efficiency.

[0042] In one embodiment, the plurality of IPM modules (204) are of different models. Thus, the power board (20) can meet the motor requirements of different power levels by replacing the IPM modules (204) with different models.

[0043] The purpose of this invention is to provide a modular servo driver power unit module, which has the advantages of flexible configuration, simple disassembly and assembly, quick replacement and maintenance of the module, and meeting customized needs.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
