[0030] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0031] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0032] See attached Figure 1-6 One of the embodiments of the present application provides a control cabinet for a robot. In actual use, the control cabinet controls the movement of the robot, and the control cabinet directly affects the speed and accuracy of the robot. The control cabinet includes a cabinet body 10 and functional modules installed in the cabinet body 10, wherein the functional modules mainly include a power supply assembly 30, a control assembly 50, and a driver assembly 40. The cabinet body 10 includes a front panel assembly 11, a rear panel assembly 12, a bottom plate assembly 13 and a cover plate assembly 14. The bottom plate assembly 13 is provided with a first mounting portion 131 and a second mounting portion 132 that are independent of each other. The front panel assembly 11 is provided with a third mounting portion 111. The power supply assembly 30, the driver assembly 40 and the control assembly 50 can all be independently assembled and independently installed in the first mounting portion 131, the second mounting portion 132 and the third mounting portion 111. The cover plate assembly 14 is covered on the front panel assembly 11, the rear panel assembly 12 and the bottom plate assembly 13.

[0033] In this embodiment, multiple installation parts are set on the bottom plate component 13 and the front panel component 11. During assembly, the power supply component 30, the control component 50, and the driver component 40 are independently installed in each installation part to achieve partitioned installation, which can enhance the stability of the system. In actual use, the front panel component 11 and the rear panel component 12 can be first assembled with the bottom plate component 13 to form a basic frame. At this time, the side of the cabinet 10 is not blocked by sheet metal, which is convenient for the operator to assemble various components in the cabinet 10. In addition, each component can be assembled independently outside the cabinet 10, which means that the assembly of different components can be carried out simultaneously, which can greatly improve the assembly efficiency. After the components are assembled, they are installed as a whole in the cabinet 10, realizing modular design, improving assembly efficiency, and facilitating later maintenance. Moreover, the overall structure of the cabinet 10 is simple, and the height space is fully utilized, so the volume of the cabinet 10 can be reduced to meet the use requirements of miniaturized robots. The power supply assembly 30, the control assembly 50 and the driver assembly 40 of the utility model can be pre-wired externally and then integrally installed in the cabinet, thereby avoiding the inconvenience of wiring in a narrow area and improving assembly efficiency.

[0034] In order to simplify the structure of the cabinet 10, facilitate the structural design of the cabinet 10 and reduce the volume of the cabinet 10, the cover assembly 14 of one embodiment of the present invention is generally U-shaped, see the attached Figure 3 The cover plate assembly 14 includes a top plate 141 and side plates 142 arranged at both ends of the top plate 141.
