[0035] The mounting assembly 10 can be applied to control devices such as servo drives or industrial controllers, and can also be applied to other devices or equipment requiring a heat dissipation bracket 100, a circuit board 300, and power devices. For ease of description, the following uses the mounting assembly 10 as an example of its application to a servo drive.

[0036] See also Figures 1 to 5 In one embodiment of the present utility model, the mounting assembly 10 includes a heat dissipation bracket 100, a circuit board 300, a first power device 400 and a connecting block 200. The heat dissipation bracket 100 is provided with a first mounting hole 101. The circuit board 300 is provided on the heat dissipation bracket 100. The first power device 400 is provided inside the heat dissipation bracket 100 and is electrically connected to the circuit board 300.

The fastener 600 passes through the first mounting hole 101 and the second mounting hole 401 in sequence and is threadedly connected to the connecting block 200.

[0037] In this embodiment, the fastener 600 passes through the first mounting hole 101 and the second mounting hole 401 in sequence, and is threadedly connected to the connecting block 200. The first mounting hole 101 and the second mounting hole 401 are through holes, and the connecting block 200 has a certain thickness. The fastener 600 is threadedly connected to the connecting block 200. Usually, the fastener 600 is provided with an external thread, and the connecting block 200 is provided with a third mounting hole 201. The third mounting hole 201 is provided with an internal thread that is adapted to be connected to the external thread.

[0041] It's understood that in a servo drive, power devices refer to those components that directly process and regulate electrical power. Power devices are responsible for converting input electrical energy into the power required to drive the motor, enabling the servo system to operate efficiently. Common power devices include, but are not limited to, power transistors, power diodes, power modules, current sensors, and power capacitors. One type of power diode can be a flat bridge rectifier.

[0042] The technical solution of the present invention, through the setting of the connecting block 200, enables the fastener 600 used to fix the power device inside the heat dissipation bracket 100 to be installed from the outside to the inside of the heat dissipation bracket 100, thereby reducing the installation difficulty of the power device inside the heat dissipation bracket 100 and improving the installation efficiency of the power device inside the heat dissipation bracket 100.

[0043] The specific structure of the servo drive will be described in detail below.

[0044] In this embodiment, the servo driver includes a heat dissipation bracket 100, a circuit board 300, a panel assembly, and a housing. The panel assembly includes components such as a panel, a display, operation buttons or indicator lights, etc. that provide a user operation and monitoring interface. The above main structures will be described in detail below.

[0045] The heat dissipation bracket 100, which can also be called a mounting bracket, provides a stable mounting base to fix the servo drive in a cabinet or device. The mounting bracket is usually fixed to the bottom or side of the casing and fixed with screws or clips to make the device stable; the heat dissipation bracket 100 includes a base 110 and a connecting frame 120. The base 110 is provided with a fan and heat dissipation fins, etc. to achieve heat dissipation of the circuit board 300 and the power devices arranged on the circuit board 300.

[0046] The circuit board 300 contains control circuitry, drive circuitry, feedback circuitry, and communication circuitry, performing signal processing and drive control. The circuit board 300 is typically mounted on a mounting bracket and connected to a power source via a cable or socket. In this embodiment, the first power device 400 is mounted on the circuit board 300. Typically, the circuit board 300 has mounting holes, through which the pins of the first power device 400 pass, and are then soldered to the other side of the circuit board 300.

[0047] The outer shell is provided on the heat dissipation bracket 100, and is usually used to protect the internal electronic components, provide structural support, and have heat dissipation and electromagnetic shielding functions. The outer shell is connected to the mounting bracket by screws or buckles and fixed in the installation position.

[0048] The panel assembly is usually set in the outer casing. The panel assembly usually includes a panel, a display, operation buttons or indicator lights, etc., which provide a user operation and monitoring interface and are installed on the panel. In addition, the display and operation buttons are connected to the internal circuit board 300 through connecting wires or connectors to realize signal transmission.

[0049] In an exemplary embodiment, see Figure 2 The heat dissipation bracket 100 includes a base 110 and a connecting frame 120 arranged on the base 110. The circuit board 300 is located on one side of the connecting frame 120 and is respectively connected to the base 110 and the connecting frame 120; the first mounting hole 101 is provided on the connecting frame 120, and the first power device 400 is provided on the inner side of the connecting frame 120.

[0050] For details on the inner and outer sides of the connecting frame 120, see Figure 2The inner side and outer side of the connecting frame 120 refer to the area formed by the base 110, the first frame edge 121, the second frame edge 122 and the third frame edge 123, with the connecting frame 120 as the boundary. The outer side of the connecting frame 120 refers to the other side outside the first frame edge 121, the second frame edge 122 and the third frame edge 123.

[0051] In a preferred embodiment, to facilitate the aligned installation of the first power device 400 and thereby improve the installation efficiency of the first power device 400, the connecting frame 120 is provided with a first limiting groove 102 on its inner side. The first limiting groove 102 has two opposing ends. The first power device 400 is installed in the first limiting groove 102 in a direction from the first end of the first limiting groove 102 to the second end of the first limiting groove 102 and is plugged into the circuit board 300. Thus, the provision of the first limiting groove 102 in this embodiment avoids the problem of rotational displacement of the first power device 400 during the fixing process, thereby effectively solving the problem of simple and effective installation in a narrow space and facilitating the miniaturization design of the driver.

[0052] In one embodiment, in order to facilitate the positioning of the connecting block 200, the connecting block 200 includes a first connecting portion 210 and a second connecting portion 220, the first connecting portion 210 and the second connecting portion 220 are arranged at an angle, the third mounting hole 201 is provided in the first connecting portion 210, and the second connecting portion 220 abuts against the connecting frame 120.

[0053] Among them, the first connecting part 210 and the second connecting part 220 are arranged at an angle. For example, the first connecting part 210 and the second connecting part 220 can be L-shaped, V-shaped, or other shapes, etc., which are not specifically limited here. The size of the angle between the first connecting part 210 and the second connecting part 220 is adapted to the shape of the second frame edge 122, which is generally a right angle. The first connecting part 210 and the second connecting part 220 are usually plate-shaped. In addition, the setting of the second connecting part 220 increases the contact area between the first power device 400 and the heat dissipation bracket 100, thereby achieving a good heat dissipation effect and improving the heat dissipation effect of the first power device 400.

[0054] Thus, in this embodiment, the connection block 200 is configured in this way to effectively fix the power device on the heat sink without any tooling assistance. Conventional screw tools can be easily used to firmly fix the power device to the heat sink through screws. This structure is stable, greatly reduces auxiliary tooling and special tools, simplifies the installation steps, improves assembly efficiency, saves costs, and improves heat dissipation capacity.

[0055] On the basis of the previous embodiment, to further improve the installation efficiency of the first power device 400, a second limiting groove 103 is provided on the side of the connecting frame 120 facing away from the circuit board 300. The second limiting groove 103 extends from the inner side of the connecting frame 120 to the outer side thereof, and the second connecting portion 220 is limited to the second limiting groove 103. Thus, in this embodiment, the second limiting groove 103 is provided to limit the position of the connecting block 200, thereby facilitating the alignment of the connecting block 200, particularly when the connecting block 200 and the first power device 400 are provided separately.

[0056] See also Figure 2 Considering that a servo drive typically includes multiple power devices, some of which are disposed outside the connecting frame 120, in order to improve the installation efficiency of these power devices, in another embodiment, the connecting frame 120 is further provided with a third limiting groove 104 for limiting the second power device 500. The third limiting groove 104 is located outside the connecting frame 120; the third limiting groove 104 has opposite ends. The second power device 500 is inserted into the third limiting groove 104 from the first end to the second end of the third limiting groove 104 and is plugged into the circuit board 300. Thus, the provision of the third limiting groove 104 in this embodiment avoids the problem of rotational displacement of the second power device 500 during the fixing process, thereby effectively solving the problem of simple and effective installation in a narrow space, facilitating the miniaturization design of the drive, and better improving heat dissipation capabilities.

[0057] In the above embodiment, the first limiting groove 102 can be directly formed on the edge of the connecting frame by a lathe or milling machine, or by injection molding. Of course, limiting ribs can also be provided on the connecting frame 120, and the number of limiting ribs can be two, three, four, etc., which enclose the first limiting groove 102. The second limiting groove 103 and the third limiting groove 104 can refer to the first limiting groove 102, and can also be directly formed on the edge of the connecting frame by a lathe or milling machine, or by injection molding.

[0058] In an exemplary embodiment, the connecting frame 120 includes a first frame edge 121, a second frame edge 122 and a third frame edge 123 connected in sequence, the first frame edge 121 and the third frame edge 123 are connected to the base 110, the first mounting hole 101 is provided in the second frame edge 122, and the first power device 400 is provided on the side of the second frame edge 122 close to the base 110.

[0059] In other embodiments, the connecting frame 120 may have only one or two frame edges, or may be formed by four or five frame edges.

[0060] The present invention also proposes a controller, which includes a shell and an installation component 10. The specific structure of the installation component 10 refers to the above embodiment. Since the present controller adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0061] The controller may be a control device such as a servo drive or an industrial controller, or may be other devices or equipment having a heat dissipation bracket 100 , a circuit board 300 and a power device.

[0062] A servo drive is the controller for a servo system, a system used to precisely control the position, speed, and torque of mechanical equipment. A servo system is based on closed-loop control, achieving precise motion control through real-time feedback and regulation.

[0063] The general workflow of a servo system is that the user sets parameters such as target position, speed or torque. These target values ​​are received and processed by the control system, and the control unit (such as a servo drive) converts the target values ​​into control signals suitable for the servo motor; control algorithms (such as PID control) are used to calculate the required output signals; the control signal drives the power circuit (such as an inverter) to convert the power supply into the voltage and current required by the servo motor, prompting the motor to move as expected; the feedback device (such as an encoder or sensor) measures the position, speed or torque of the motor in real time and feeds this information back to the control unit; the control unit adjusts the control signal based on the error between the feedback signal and the set target to reduce the error and ensure that the motor reaches the set target; the system monitors the status of the motor and drive to ensure that they operate within a safe range and provides protection functions such as overload and overheating.
