The fan direction is air suction, and the outer cavity needs to achieve a certain sealing effect to penetrate the entire driver heat sink, with poor efficiency; 3. There is no bundling point for the power output line of the driver, and there is a risk of connector detachment during transportation vibration; 4. The power output line of the driver and the encoder communication line are relatively long, and it is easy to interfere with other signals externally or be interfered by other signals. Summary of the Invention

[0011] A driver, which is mounted on the driver mounting plate, and a heat sink and high-power electrical components are provided on the driver.

[0012] The driver mounting plate, the bottom plate, the left side plate, and the fan bracket form an air duct cavity, and the heat of the air duct cavity is discharged from the left side plate through the fan.

[0013] A ventilation opening is provided on the left side plate.

[0014] Control components are installed on the guide rail of the fan bracket, and first retaining edges are symmetrically bent and arranged on the fan bracket.

[0027] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below.

[0028] As Figures 1 to 6 shown, a robot control cabinet includes:

[0029] The control cabinet main body 2 is composed of a bottom plate 21, a left side plate 22 and a right side plate 23, wherein the left side plate 22 and the right side plate 23 are detachably mounted on the bottom plate 21;

[0030] The driver mounting plate 3 is mounted on the bottom plate 21 of the control cabinet main body 2 at the bottom and on the left side plate 22 on the left side. A sealing gasket can be added at the contact between the driver mounting plate 3 and the bottom plate 21 and the left side plate 22 to improve the sealing performance;

[0031] The fan bracket 4 is mounted vertically on the right side of the driver mounting plate 3, and a fan 41 and a guide rail 42 for mounting electrical components are horizontally arranged at the upper end of the fan bracket 4. The high-voltage and control circuits are separately arranged through the fan bracket 4;

[0032] The wiring harness mounting plate 5 is mounted on the left side plate 22 on the left side and on the fan bracket 4 on the right side, and a process hole 51 is provided above the wiring harness mounting plate 5;

[0033] The driver 6 is mounted on the driver mounting plate 3, and a heat sink 61 and high-power electrical components 31 are provided on the driver 6. The high-power electrical components 31 include components with large heat dissipation amounts such as a braking resistor 31a and a switching power supply 31b.

[0034] The driver mounting plate 3, the bottom plate 21, the left side plate 22 and the fan bracket 4 form an air duct cavity 7, and the heat of the air duct cavity 7 is discharged from the left side plate 22 through the fan 41.

[0035] A ventilation opening 221 is formed in the left side plate 22.

[0036] A control component 47 is installed on the guide rail 42 of the fan bracket 4. First baffle edges 44 are symmetrically bent and arranged on the fan bracket 4. The fan bracket 4 is used to isolate the strong and weak electricity. At the same time, heat can be easily discharged through the air duct cavity 7, reducing the temperature inside the control cabinet. Moreover, with the air suction effect of the fan, the heat of the controller is discharged. By optimizing the layout of the power harness and the communication harness, the interference of the power line to the communication line is significantly reduced.

[0037] As Figure 2 、 Figure 3 and Figure 4 shown, more than 3 fans 41 are arranged at the bottom of the fan bracket 4. The fans 41 are arranged horizontally along the air duct cavity 7. Through the operation of the fans 41, the heat in the air duct cavity 7 can be discharged from the ventilation opening 221 of the left side plate 22, thereby achieving the effect of reducing the temperature inside the robot control cabinet 1. A guide rail 42 is installed on the fan bracket 4, and a control component 47 is installed on the guide rail 42, including a motion controller and a digital quantity IO module.

[0038] As Figure 3 、 Figure 5 and Figure 6 shown, threaded through holes 45 and 46 are provided on the fan bracket 4. The fan bracket 4 is fixed on the wire harness mounting plate 5 through the threaded through holes 45 and 46. Three fan mounting holes are provided at the bottom of the fan bracket 4 for installing the fans 41. The first baffle edges 44 bent on both sides of the fan bracket 4 are used to fix the wire harness of the control circuit. A bent second baffle edge 52 is provided at the upper end of the wire harness mounting plate 5, which is connected to the left side plate 22. A third baffle edge 53 is provided at the lower end of the wire harness mounting plate 5, which is connected to the fan bracket 4. The grounding performance of the wire harness mounting plate 5 is increased through the contact of the second baffle edge 52 and the third baffle edge 53, thereby improving the anti-interference ability of the communication wire harness 8 installed thereon. A process hole 51 is provided on the wire harness mounting plate 5. The communication wire harness 8 and the power wire harness 9 can be quickly fixed through the process hole 51, thereby improving the reliability of connection and operation.

[0039] The wire harness mounting plate 5 is provided with an upwardly bent second baffle edge 52 and a downwardly bent third baffle edge 53.

[0040] The communication wire harness 8 is fixed above the process hole 51 of the wire harness mounting plate 5, and the power wire harness 9 is fixed below the process hole 51. By making a layered treatment of the power wire harness 9 and the communication wire harness 8, the interference of the power wire harness 9 to the communication wire harness 8 can be significantly reduced. At the same time, due to the presence of the wire harness mounting plate 5, the risk of connector detachment is effectively avoided and the reliability is increased.

[0041] During use, inside the control cabinet main body 2 of the robot control cabinet 1, the control circuits for high-voltage and low-voltage are separated by the fan bracket 4, which can effectively reduce the interference of high-voltage on the control components 47. Additionally, through the fan 41 installed on the fan bracket 4, the heat in the air duct cavity 7 can be effectively discharged, reducing the impact of high heat on the electrical components inside the control cabinet main body 2. At the same time, due to the air suction effect of the fan 41, the heat of the control components 47 can be sucked into the air duct cavity 7 for joint discharge. Moreover, the wire harness mounting plate 5 located above the driver 6 can effectively increase the reliability of the wire harness. By arranging the communication wire harness 8 and the power wire harness 9 in layers, the interference on the communication wire harness 8 is reduced, and the overall anti-interference ability is improved.
