[0040] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0041] As Figures 1 to 4 is a schematic structural diagram of an embodiment of the robot control cabinet of the present invention. As Figure 2As shown in the figure, this embodiment includes a cabinet body 1, a partition 11 and an intake fan 2; the partition 11 is arranged inside the cabinet body 1, and the partition 11 divides the cabinet body 1 into two spaces, namely a sealed space 12 and a semi-open space 13; the sealed space 12 is not connected to the outside; the intake fan 2 is arranged at the semi-open space 13, and the intake fan 2 is arranged on a plane of the cabinet body 1, and the intake fan 2 conveys the air outside the cabinet body 1 into the semi-open space 13 of the cabinet body 1; an air exchange hole 14 is arranged on the cabinet body 1 at the semi-open space 13 for the air in the semi-open space 13 to flow out of the semi-open space 13; the partition 11 is located on one side of the sealed space 12 for installing electrical components.

[0042] This embodiment can be applied to a robot control system. The electronic components in the robot control cabinet that require dust prevention are arranged in the sealed space 2, and the electronic components with low requirements for dust prevention performance are arranged in the semi-open space 3.

[0043] When this embodiment is in use, the intake fan 2 can be arranged on the ground or the top surface or the side surface of the semi-open space 13. The intake fan 2 conveys the external air into the semi-open space 13. The gas pressure in the semi-open space 13 increases, so that there is an internal and external air pressure difference at the air exchange hole 14 and drives the other air in the semi-open space 13 to flow outwards, forming a stable air circulation. It should be noted that if the intake fan 2 is arranged on the bottom surface of the semi-open space 2, wheels or support feet need to be installed on the bottom surface of the cabinet body 1 to lift the bottom surface of the cabinet body 1 so that air can enter from the gap between the bottom surface of the cabinet body 1 and the ground.

[0044] As a specific implementation manner, the intake fan 2 is arranged on the side surface of the semi-open space 13 away from the partition 11, and the intake fan 2 is arranged at a position close to the upper end of the cabinet body 1; the air exchange hole is arranged at the lower half part of the semi-open space 13. Usually, the fan is an axial flow fan. At this time, the intake fan 2 conveys air towards the partition 11, and can effectively cool the partition at the position corresponding to the intake fan 2. At the same time, due to the characteristic that the lower the gas temperature, the greater the density, the intake fan 2 inputs cooling air into the semi-open space 13 from the upper end of the cabinet body 1. The density of the cooling air 13 is greater than the density of the heated air in the cabinet body 1. The cooling air 13 will move downward. At the same time, the continuously introduced cooling air by the intake fan 2 also makes the pressure in the upper part of the semi-open space greater, so that the air in the lower part of the semi-open space 13 continuously takes away heat through the air exchange hole 14.

[0045] As a specific implementation manner, the partition 11 can be in an I shape, and the partition 11 can also be set into a space shape according to the shape requirements of the electronic components, such as Figure 2As shown, the partition 11 includes an upper vertically - arranged part, a lower vertically - arranged part, and a connecting part that horizontally connects the upper and lower vertically - arranged parts. The partition with a special structure facilitates the position design and layout of the components inside the robot control cabinet according to requirements.

[0046] Furthermore, as Figure 3 , Figure 4 shown, it further includes a cooling fan 3 and an orifice plate 15. The orifice plate 15 divides the semi - open space 13 into an upper cavity 131 and a lower cavity 132; the intake fan 2 is arranged on the upper cavity 131; the cooling fan 3 is arranged in the lower cavity 132. The cooling fan 3 drives the air in the lower cavity 132 to move towards the partition 11 and dissipates heat from the partition 11. Vent holes for exhausting the heated air are arranged on both sides of the lower cavity 132 between the cooling fan 3 and the partition 11.

[0047] The orifice plate 15 can be a plate with several through - holes, or it can be a filter mesh. The orifice plate 15 can also be a ring with a through - hole in the middle or just a marker for identifying the boundary between the upper cavity 131 and the lower cavity 132.

[0048] As a specific implementation manner, when the orifice plate 15 is a ring with a through - hole in the middle or just a marker for identifying the boundary between the upper cavity 131 and the lower cavity 132, the function of the orifice plate 15 is only to divide the semi - open space 13. As a specific implementation manner, when the orifice plate 15 is a plate with several through - holes or a filter mesh, the orifice plate 15 can filter the air flowing from the upper cavity 131 to the lower cavity 132, such as filtering large - particle dust, making it safer to place electronic components in the lower cavity.

[0049] During the use of this embodiment, the axis of the cooling fan 3 is horizontal and perpendicular to the partition 11. The cooling fan 3 can promote the air flow in the lower cavity 132, enhance the heat dissipation ability of the partition 11 at the lower cavity 132. The air reaches the partition 11 under the action of the cooling fan 3 and spreads around. After the air dissipates heat from the partition 11, it flows out of the lower cavity 132 through the vent holes 14 and forms a stable lateral - flowing air current. The cooling fan 3 can also rapidly cool the air flowing from the upper cavity 131 to the lower cavity 132 and exhaust it from the lower cavity 132, increasing the heat dissipation ability of this embodiment.

[0050] Further, it further includes a power supply module 4, a control unit 5, a servo drive module 6, and a transformer 7. The transformer 7 converts the input voltage into the voltage required by the device, such as the voltage required by the power supply module 4; the power supply module 4 can convert alternating current into direct current as needed and supply power to the control unit 5 and the servo drive module 6 respectively. The control unit 5 is the brain of the robot control cabinet. The control unit 5 includes a central processing unit or a chip unit with similar functions. The control unit 5 can control modules with specific functions such as the servo drive module 6 to act according to instructions.

[0051] The power supply module 4, the control unit 5, and the servo drive module 6 have relatively high requirements for dust prevention. Therefore, the power supply module 4, the control unit 5, and the servo drive module 6 are arranged in the enclosed space 12, and the power supply module 4, the control unit 5, and the servo drive module 6 are respectively installed on the surface of the partition 11; for the electronic components with relatively low dust requirements in this embodiment, they can be arranged in the semi-open space 13, such as the transformer 7. The electronic components with relatively low dust requirements can also be arranged in the upper cavity 131 or the lower cavity 132 of the semi-open space 13 as needed. The stable air flow in the semi-open space 13 will prevent dust from depositing on the electronic components and ensure the safety of the device. As a specific implementation, this embodiment may further include a safety unit, and the safety unit is arranged in the enclosed space 12.

[0052] As a specific implementation, the transformer 7 is arranged inside the lower cavity 132, and the cooling fan 3 is arranged between the transformer 7 and the partition 11; a ventilation hole 14 is arranged in the middle of the side of the lower cavity 132 away from the partition 11, and the position of the ventilation hole 14 corresponds to the position of the transformer 7. The cooling air moves downward from the upper cavity 131, cools the transformer 7 and then moves towards the ventilation hole 14 on the side away from the partition 11, and is discharged from the lower cavity 132 through the ventilation hole 14.

[0053] At the same time, part of the air in the lower cavity 132 moves towards the partition 11 through the cooling fan 3. The moving air cools the partition and then moves towards the ventilation holes 14 on both sides, and is discharged from the lower cavity 132 through the ventilation holes 14 on both sides.

[0054] As a specific implementation, the power supply module 4 and the control unit 5 are arranged at the upper part of the enclosed space 12, and the servo drive module 6 is arranged at a position corresponding to the cooling fan 3. Since the servo drive module 6 includes an integrated circuit and power devices and generates a large amount of heat, the cooling fan 3 forcibly cools the partition 11 at the position where the servo drive module 6 is installed, which helps to reduce the temperature of the servo drive module 6 and ensure the stable operation of the device. As a specific implementation, the power supply module 4 and / or the control unit 5 are arranged at a position corresponding to the intake fan 2, and the cooling air introduced by the intake fan 2 can also dissipate heat from the partition 11 at the position where the power supply module 4 and / or the control unit 5 are installed, reducing the temperature of the power supply module and / or the control unit 5 and ensuring the stable operation of the device.

[0055] Furthermore, a circulation device 8 is further included. The circulation device 8 causes a gas circulation to be formed inside the enclosed space 12, improving the heat dissipation capacity of the enclosed space. Specifically, the heat exchange capacity between the air and the electronic components inside the enclosed space 12 is enhanced through the gas circulation, and at the same time, the heat exchange between the air inside the enclosed space 12 and the cabinet 1 where the enclosed space 12 is located is enhanced.

[0056] The circulation device 8 includes a circulation fan 81 and an air flow pipeline 82. The circulation device 8 is arranged inside the enclosed space 12 and on the side surface far from the partition 11. The air flow pipeline 82 is hollow tubular and vertically arranged, and gaps are provided between both ends of the air flow pipeline 82 and the upper and lower inner surfaces of the enclosed space 12. The circulation fan 81 and the air flow pipeline 82 are in an up-and-down positional relationship, that is, the circulation fan 81 is arranged at the upper end of the air flow pipeline 82, or the circulation fan 81 is arranged at the lower end of the air flow pipeline 82; one end of the air flow pipeline 82 is arranged at the air inlet of the circulation fan 81, and the circulation fan 81 sucks the air inside the air flow pipeline 82 and drives the air to move towards the partition 11.

[0057] As a specific implementation, the power supply module 4 and the control unit 5 are arranged in the upper half of the enclosed space 12; the servo drive module 6 is arranged in the lower half of the enclosed space 12; the circulation fan 81 is arranged at the upper end of the air flow pipeline 82, and the circulation fan 81 corresponds to the position of the power supply module 4 and / or the control unit 5, and the circulation fan 81 drives the air to move towards the power supply module 4 and / or the control unit 5. At this time, the air flow direction inside the enclosed space 12 is that the circulation fan 81 located at the upper part of the enclosed space 12 drives the air horizontally to the power supply module 4. After the air cools the power supply module 4, it moves downward, and at the same time, it continuously dissipates heat through the partition 11. After the air cools the servo drive module 6 at the lower part of the enclosed space 12, it moves in a direction away from the partition 11. The air moves upward through the air flow pipeline 82 to the circulation fan 81 for the next cycle, and at the same time, it cools down by continuously exchanging heat with the outside through the structural members and side panel of the enclosed space 12.

[0058] As a specific implementation, the air flow pipeline 82 is in a hollow manner. Specifically, the air flow pipeline 82 can be a square pipe, a circular pipe, or a material with a C-shaped or concave cross-section combined with the side plate of the sealed space 12 to form a hollow tube.

[0059] Furthermore, it further includes a shunt plate 16. The shunt plate 16 is arranged in the lower cavity 132, and the shunt plate 16 is between the transformer 7 and the cooling fan 3. The shunt plate 16 is arranged along the height direction. The lower end of the shunt plate 16 is connected to the bottom plane inside the lower cavity 132, and there is a gap between the two ends of the shunt plate 16 along the horizontal direction and the side plates of the lower cavity 132; there is a gap between the cooling fan 3 and the shunt plate 16.

[0060] When this embodiment is in use, the air in the lower cavity 132 reaches the air inlet of the cooling fan 3 through the gaps between the two ends of the shunt plate 16 along the horizontal direction and the side plates of the lower cavity 132, and the air is driven by the cooling fan 3 to move towards the partition plate 11. The setting of the shunt plate 16 can prevent the air cooling the transformer 7 from directly moving towards the cooling fan, reduce the air temperature at the air inlet of the cooling fan 3, and improve the cooling effect.

[0061] As a specific implementation, as Figure 2 shown, the upper end of the shunt plate 16 is connected to the partition plate 11 to prevent the air cooling the transformer 7 from reaching the air inlet of the cooling fan 3 through the upper end of the shunt plate 16.

[0062] As a specific implementation, as Figure 4 shown, a plurality of rows of vertically arranged air exchange holes 14 are provided on the side plate of the lower cavity 132 away from the partition plate 11. Some of the air exchange holes 14 are arranged in the middle of the side plate of the lower cavity 132 away from the partition plate 11, and some of the air exchange holes 14 are arranged at both edges of the side plate of the lower cavity 13 away from the partition plate 11, corresponding to the gaps between the shunt plate 16 and the side plates of the lower cavity 132. The transformer 7 is arranged in the middle of the bottom surface of the lower cavity 132. The air exchange holes 14 in the middle position on the side plate away from the partition plate 11 are mainly used to discharge the air cooling the transformer 7, and the air exchange holes 14 near the edge on the side plate away from the partition plate 11 are used to provide cooler air for the cooling fan, so as to better cool the partition plate. As a specific implementation, as Figure 5As shown, an air supply channel can also be set in the lower cavity 132. Specifically, a tubular channel can be set between the side plate of the lower cavity 132 away from the partition 11 and the diverter plate, so as to isolate the air supplied to the cooling fan 3 from the air cooling the transformer 7. Specifically, tubular components can be used or two parallel baffles can be set between the side plate of the lower cavity 132 away from the partition 11 and the diverter plate. The two baffles and the diverter plate 16 isolate the transformer 7 from the cooling fan 3. At the same time, a channel for supplying air to the cooling fan 3 is formed between the baffle and the side plates of the lower cavity 132 on both sides of the partition 11.

[0063] As a specific implementation, air ventilation holes 14 may be provided for the cooling fan 3 on the side panels of the lower cavity 132 on both sides of the partition 11 corresponding to the two ends of the diverter plate 16 .

[0064] Furthermore, a heat sink 9 is provided between the cooling fan 3 and the partition 11. The heat sink 9 is mounted on the partition 11. The heat sink 9 improves the cooling capacity of the partition 11 and further improves the heat dissipation capacity of the electronic components in the enclosed space 12. The heat sink 9 can be made of a metal material with a high thermal conductivity, specifically a copper alloy or an aluminum alloy.

[0065] As a specific implementation, the heat sink 9 includes a heat sink 91 and heat sink fins 92. The heat sink fins 92 are in the form of sheets and are arranged horizontally and vertically to the heat sink 91. The heat sink fins 92 are arranged in a plurality of pieces, and the space between each two heat sink fins 92 can serve as a gas flow channel to guide the flowing air. Along the horizontal direction of the heat sink fins 92, ventilation holes are arranged at corresponding positions of the two side plates corresponding to the corresponding lower cavity 132, such as Figure 5 shown.

[0066] The electronic components in the enclosed space are installed on the partition 11, and the heat of the electronic components flows to the partition 11, and the heat on the partition 11 flows to the heat sink 91 and the heat sink fins 92. The cooling fan 3 drives the air to move toward the partition 11, and the moving air reaches the heat sink fins 92 and the heat sink 91. The flowing air takes away the heat on the heat sink fins 92 and the heat sink 91, and moves to both sides along the heat sink fins 92, and is discharged from the lower cavity 132 through the ventilation holes at the corresponding positions of the heat sink fins 92, thereby improving the heat dissipation capacity of the electronic components in the enclosed space 12.

[0067] As a specific implementation, the heat sink 9 can be made of aluminum alloy, specifically 6061 aluminum alloy or 6063 aluminum alloy. The heat sink 9 can also be integrally formed, for example, integrally formed by extruding aluminum alloy.

[0068] As a specific implementation manner, the servo drive module has two groups of 6 bits, and the cooling fan has two of 3 bits; the two groups of servo drive modules are arranged in parallel at the same height on the partition 11, and the positions of the two cooling fans 3 correspond to the two groups of servo drive modules 6. When implementing this embodiment specifically, one of the two groups of servo drive modules 6 is the main servo drive module, and the other group is the auxiliary servo drive module.

[0069] Furthermore, the enclosed space 12 includes a movable door 121, and the movable door 121 is arranged on the side of the enclosed space 12 away from the partition 11. The movable door 121 is hinged to the enclosed space 12, and a sealing material is arranged between the movable door 121 and the enclosed space 12.

[0070] The movable door 121 is away from the partition 11. When the movable door is opened, it is more convenient to install and repair the electronic components arranged in the enclosed space 12, and the accessibility is good. At this time, the circulation device 8 is arranged on the movable door 121.

[0071] As a specific implementation manner, the sealing material can be made of materials with elasticity and good sealing performance such as rubber strips and soft plastics. The sealing material can be arranged at the edge of the movable door 121, or the sealing material can also be arranged at the connection between the enclosed space 12 and the movable door. When using the sealing material with elasticity and good sealing performance, when the movable door 121 is closed, the movable door 121 acts on the sealing material and deforms the sealing material. At this time, the sealing material can achieve a good sealing effect.
