[0041] The embodiments of the utility model will be described below in combination with Figures 1 to 7

[0042] According to the embodiments of the utility model, on the one hand, a modular multi-output pulse power supply is provided. The modular multi-output pulse power supply comprises: a device frame 1, a plurality of pulse modules 2, a switch module 3 and a control module 4. The plurality of pulse modules 2 are arranged at intervals in the device frame 1. The switch module 3 is arranged in the device frame 1 and is electrically connected with the plurality of pulse modules 2; the control module 4 is arranged on the side wall of the device frame 1 and is electrically connected with the plurality of pulse modules 2.

[0043] The device frame 1 provides mounting space for the pulse module 2, the switch module 3 and the control module 4, and the installation of the entire pulse power supply is completed by mounting and fixing the device frame 1. The commercial power can be supplied to the pulse module 2 through the switch module 3 to provide power supply for the pulse module 2. Each pulse module 2 can output pulse power, and the external dimensions and internal structure of each pulse module 2 are the same. The control module 4 can control each pulse module 2 to output pulse current with required parameters according to requirements.

[0044] This pulse power supply adopts a modular design, the internal structure is simplified, the layout is simple, the line connection is less, and each module can be taken out separately for replacement or maintenance, which is convenient for maintenance. In this way, it is not necessary to reserve maintenance space in the device frame 1, the internal space utilization rate of the device frame 1 is high, so the overall volume of the pulse power supply is relatively small, and the occupied installation space is also relatively small.

[0045] In one embodiment, the device frame 1 is arranged above the electroplating equipment.

[0046] The device frame 1 is arranged above the electroplating equipment and then supplies pulse current to the electroplating equipment through the pulse module 2. This installation mode does not occupy additional space of the factory, saves land area and reduces economic cost.

[0047] ​Of course, in other embodiments, the pulse power supply can also be arranged near the electroplating device.

[0048] In one embodiment, the device frame 1 arranges the side wall of the control module 4 as an inclined surface.

[0049] As shown in the drawings, Figure 1 In the present embodiment, the device frame 1 is not a complete cuboid, and the side wall of the control module 4 is arranged as an inclined surface, and the inclined direction of the inclined surface is inclined from top to bottom to the inside of the device frame 1.

[0050] Since the device frame 1 is arranged above the electroplating device, the overall height is high, and the control module 4 is arranged on the inclined surface, which is convenient for workers to watch and operate.

[0051] In other embodiments, the device frame 1 can also be a cuboid, or when the installation height of the device frame 1 is low, the inclined direction of the inclined surface can also be changed, that is, the inclined direction is from top to bottom to the outside of the device frame 1.

[0052] In one embodiment, the device frame 1 arranges the side wall opposite to the control module 4 with a mounting port for connecting the power supply and the switch module 3.

[0053] As shown in the drawings, Figure 2 The device frame 1 arranges the opposite side of the control module 4 with a mounting port, and the switch module 3 is arranged at the mounting port and fixedly connected with the inner wall of the device frame 1. Through the mounting port, the power supply can be conveniently delivered to the switch module 3 through the cable.

[0054] In other embodiments, the mounting port can also be arranged on other side walls.

[0055] In one embodiment, four pulse modules 2 are arranged along the length direction of the device frame 1.

[0056] The number and installation method of the pulse module 2 can be adjusted according to the output demand and the internal space of the device frame 1. Specifically, as shown in the drawings, Figure 1 , Figure 2 In the present embodiment, four pulse modules 2 are arranged. The four pulse modules 2 are arranged along the length direction of the device frame 1 and are separated by the switch module 3, that is, two of them are located on one side of the switch module 3, and the other two are located on the other side of the switch module 3.

[0057] In other embodiments, other arrangement methods can also be used, such as two rows and two columns, two rows and three columns, and other array forms. The number and installation method of the pulse module 2 are not limited in the present embodiment.

[0058] In one embodiment, the pulse module 2 comprises a shell 21, a power conversion circuit and a pulse generation circuit, the power conversion circuit and the pulse generation circuit are arranged in the shell 21, the switch module 3 is electrically connected with the power conversion circuit, the power conversion circuit and the pulse generation circuit are electrically connected, and the control module 4 is electrically connected with the pulse generation circuit.

[0059] The power conversion circuit can convert the power energy delivered by the switch module 3 into electric energy suitable for the pulse generation circuit, and then deliver the converted electric energy to the pulse generation circuit, and the pulse generation circuit generates a pulse current with corresponding pulse parameters according to the control signal sent by the control module 4.

[0060] In one embodiment, the front side plate of the shell 21 is provided with a handle 23.

[0061] As shown in Figure 4 , the shell 21 is in the shape of a cuboid, both ends of the front side plate are provided with two handles 23, the handle 23 is approximately U-shaped, the handle 23 is arranged in the vertical direction, and both ends are fixedly connected with the front side plate. After the handle 23 is arranged, it is convenient for the staff to carry the pulse module 2.

[0062] In one embodiment, the rear side plate of the shell 21 is provided with a pull handle 24.

[0063] As shown in Figure 5 , a pull handle 24 is arranged on the rear side plate of the shell 21, the shape of the pull handle 24 is also approximately U-shaped, but the arrangement direction of the pull handle 24 is perpendicular to the arrangement direction of the handle 23. Moreover, the pull handle 24 is rotatable, and when not in use, the pull handle 24 is in the state shown in Figure 5 , and is attached to the rear side plate, and when in use, it can be turned upward. After the pull handle 24 is arranged, it is also convenient for the staff to carry the pulse module 2.

[0064] In some embodiments, the pulse module 2 further comprises a water cooling assembly arranged in the shell 21.

[0065] Since the power conversion circuit and the pulse generation circuit in the shell 21 will generate heat when working, heat dissipation and cooling are needed to ensure the normal operation of the power conversion circuit and the pulse generation circuit. In the related art, the air cooling heat dissipation mode is mostly used, but this heat dissipation mode needs to open a through hole on the equipment frame 1, which will result in poor sealing of the equipment frame 1, poor protection of the internal electrical elements, and higher requirements for the working environment. The water cooling heat dissipation mode can make the equipment frame 1 into a frame with better sealing, which can well protect the internal electrical elements, the external environment has less interference on the electrical elements, and the range of application is wider.

[0066] In one embodiment, the water-cooling assembly includes: an inlet connector 221, an outlet connector 222, and a water circulation pipe. The inlet connector 221 and the outlet connector 222 are disposed on the side wall of the housing 21, and the water circulation pipe is disposed inside the housing 21 and connected to the inlet connector 221 and the outlet connector 222.

[0067] like Figure 5 As shown, both the inlet connector 221 and the outlet connector 222 are located on the rear panel of the housing 21. The inlet connector 221 is connected to the external water supply pipe, and the outlet connector 222 is connected to the external water outlet pipe. The water circulation pipe is located inside the housing 21. The water circulation pipe can be U-shaped, serpentine, or other shapes. One end of the water circulation pipe is connected to the inlet connector 221, and the other end is connected to the outlet connector 222.

[0068] The inlet connectors 221 of multiple pulse modules 2 can be connected in parallel to an external water supply pipeline, and the outlet connectors 222 can be connected in parallel to an external water outlet pipeline.

[0069] The working process of the modular multi-output pulse power supply provided in this embodiment is described below:

[0070] Switching module 3 connects to the mains power supply and provides power to each pulse module 2. Control module 4 sends control signals to pulse modules 2 as needed, causing them to output pulse power with the required pulse parameters. During operation, external water supply pipes supply cooling water to the water circulation pipes via inlet connector 221 to dissipate heat from the pulse modules 2. The used cooling water flows out to the external outlet pipes via outlet connector 222.

[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
