Description

Technical Field

[0001] This invention belongs to the field of servo controller devices, and specifically relates to a servo controller that is easy to assemble and disassemble. Background Technology

[0002] A servo system is a closed-loop automatic control system with high-precision motion control at its core. Through real-time feedback and dynamic adjustment, it enables the output position, speed, or torque to accurately follow the input command signal. It is widely used in fields that require high-precision, high-response, and high-stability motion control and is the core execution unit of modern industrial automation and intelligent manufacturing.

[0003] The servo controller is the core control unit of a servo system. It receives command signals and feedback signals, and outputs drive signals through algorithm calculations to control parameters such as the position, speed, and torque of the servo motor. Traditional servo controllers have their printed circuit board (PCB) components layered and fixed inside the controller housing. This makes disassembling and reassembling the PCB components difficult when debugging or repairing the controller, increasing overall maintenance time. Furthermore, the lack of precise internal positioning in the servo controller makes it prone to wiring misalignment or module misalignment during disassembly and reassembly, increasing the risk of secondary servo controller failures. Summary of the Invention

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a servo controller that is easy to disassemble and assemble, so as to solve the problems of difficult disassembly and assembly of printed circuit boards in existing servo controllers, and the easy occurrence of wiring misalignment or module installation misalignment during assembly.

[0005] To achieve the above objectives, the present invention provides a servo controller that is easy to assemble and disassemble, comprising: The mounting housing has an opening at one end. Inside the mounting housing are a drive board assembly, a bleed plate assembly, and a capacitor assembly. The capacitor assembly is connected to the bleed plate assembly, and the bleed plate assembly is connected to the drive board assembly. The drive plate assembly, the bleed plate assembly, and the capacitor assembly are arranged at intervals within the housing; The drive plate assembly and the discharge plate assembly are detachably connected to the bottom wall of the mounting housing, and the capacitor assembly is detachably connected to the side wall of the mounting housing. The mounting housing has multiple mounting interfaces on its sidewall facing the drive board assembly, and the drive board assembly communicates with an external connector through the mounting interfaces.

A first mounting space is formed inside the first mounting bracket. A drive module is provided in the first mounting space. The drive module is attached to the bottom surface of the first mounting bracket. The drive module, the bottom surface of the first mounting bracket, and the bottom surface of the mounting housing form a heat conduction channel.

[0007] As a further improvement of the present invention, an amplifier board is provided between the first mounting bracket and the second mounting bracket. The amplifier board is connected to the drive module and is detachably connected to the first mounting bracket by screws.

[0008] As a further improvement of the present invention, the second mounting bracket is provided with a drive plate on the side opposite to the first mounting bracket, and a control plate is provided at intervals on the side opposite to the second mounting bracket of the drive plate, and a plurality of first pillars are provided between the drive plate and the control plate.

[0009] As a further improvement of the present invention, the first mounting bracket, the power amplifier board, the second mounting bracket, the driver board and the control board are connected by long screw threads.

[0010] As a further improvement of the present invention, the vent plate assembly includes a vent plate, which is spaced apart from the mounting housing. A plurality of second pillars are provided between the vent plate and the mounting housing. One end of each second pillar is connected to the vent plate, and the other end is connected to the bottom wall of the mounting housing.

[0011] As a further improvement of the present invention, the mounting housing is connected to the drive plate assembly, the discharge plate assembly and the capacitor assembly by screws from the outside to the inside.

[0013] As a further improvement of the present invention, the mounting interface is also provided with an adapter bracket, which is fixed on the side wall of the mounting housing, and the first power output connector and the second power output connector are both connected to the mounting interface through the adapter bracket.

[0014] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0015] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: (1) The servo controller of the present invention is easy to disassemble and assemble.

[0023] Example: Please see Figures 1-5 The servo controller in a preferred embodiment of the present invention includes a mounting housing 1 with an opening at one end. The mounting housing 1 contains a drive board assembly 2, a bleed plate assembly 3, and a capacitor assembly 12. The capacitor assembly 12 is connected to the bleed plate assembly 3, and the bleed plate assembly 3 is connected to the drive board assembly 2. The drive board assembly 2, the bleed plate assembly 3, and the capacitor assembly 12 are arranged at intervals within the housing. The drive board assembly 2 and the bleed plate assembly 3 are detachably connected to the bottom wall of the mounting housing 1, and the capacitor assembly 12 is detachably connected to the side wall of the mounting housing 1. Multiple mounting interfaces are provided on the side wall of the mounting housing 1 facing the drive board assembly 2, through which the drive board assembly 2 communicates with an external connector.

[0024] The servo controller of this invention, which is easy to disassemble and assemble, separates the drive board assembly 2, the bleeder board assembly 3, and the capacitor assembly 12 within the mounting housing 1, and all are detachably connected to the mounting housing 1. This allows for direct disassembly and assembly of the drive board assembly 2, the bleeder board assembly 3, and the capacitor assembly 12, without interference between the components when they are removed from the mounting housing 1, facilitating the overall disassembly and assembly of the servo controller. Furthermore, in this invention, the drive board assembly 2, the bleeder board assembly 3, and the capacitor assembly 12 are first separated and then connected sequentially. The servo controller and the external connector are both located on one side wall of the mounting housing 1, ensuring that the internal structure of the servo controller and the external interconnection lines do not interfere with or become entangled. This facilitates the disassembly and reinstallation of the servo controller, improves the efficiency of servo controller disassembly and assembly, and reduces maintenance time.

[0025] Furthermore, the mounting housing 1 in this invention is also provided with an end cap, which is detachably connected to the mounting housing 1, facilitating the assembly and disassembly of the servo controller. Optionally, the side wall where the mounting interface is located is offset from the side wall connecting to the capacitor assembly 12 to avoid interference between the external connector and the capacitor assembly 12. The circuit board structure involved in the easily assembled and disassembled servo controller of this invention is all a printed circuit board. Optionally, the outer wall of the mounting housing 1 is also provided with mounting lugs for connecting and fixing the easily assembled and disassembled servo controller to an external servo system.

[0026] Further, as an optional embodiment of the present invention, the drive board assembly 2 includes a first mounting bracket 208 and a second mounting bracket 205 stacked vertically. The first mounting bracket 208 is attached to the bottom surface of the mounting housing 1, and a first mounting space is formed within the first mounting bracket 208. A drive module 209 is disposed within the first mounting space, and the drive module 209 is attached to the bottom surface of the first mounting bracket 208. A heat conduction channel is formed between the drive module 209, the bottom surface of the first mounting bracket 208, and the bottom surface of the mounting housing 1. The present invention uses the first mounting bracket 208 and the second mounting bracket 205 to fix the drive board assembly 2, facilitating the assembly and disassembly of the drive board assembly 2 from the mounting housing 1. In addition, the form in which the drive module 209 is attached to the first mounting bracket 208 and the mounting housing 1 respectively facilitates the conduction of heat generated by the drive module 209 to the outside of the servo controller, facilitating heat dissipation of the drive module 209 and ensuring the stable operation of the servo controller.

[0027] Furthermore, there are two drive modules 209, and each drive module 209 has lugs on both sides. The two drive modules 209 are connected to the first mounting bracket 208 through the lugs. The first mounting bracket 208 has a groove-shaped structure. When the drive module 209 is installed on the first mounting bracket 208, its bottom surface can form a direct conduction with the mounting housing 1 for heat dissipation. A heat dissipation gap is left at the top of the drive module 209 to further enhance the heat dissipation effect of the drive module 209.

[0028] Furthermore, as an optional embodiment of the present invention, a power amplifier board 206 is further provided between the first mounting bracket 208 and the second mounting bracket 205. The power amplifier board 206 is connected to the driver module 209, and is detachably connected to the first mounting bracket 208 by screws. Optionally, the signal terminal connection holes of the power amplifier board 206 are connected to the signal terminals of the driver module 209, and the two are connected by solder.

[0029] Furthermore, as an optional embodiment of the present invention, the second mounting bracket 205 of the present invention is further provided with a drive plate 204 on the side opposite to the first mounting bracket 208. Control plates 202 are spaced apart on the side of the drive plate 204 opposite to the second mounting bracket 205. A plurality of first support pillars 203 are provided between the drive plate 204 and the control plates 202. The plurality of first support pillars 203 can suspend the control plates 202 above the second mounting bracket 205, facilitating heat dissipation and disassembly of the control plates 202. In addition, the drive plate 204 is mounted on the second mounting bracket 205 by fixing screws 207.

[0030] More preferably, the first mounting bracket 208, the power amplifier board 206, the second mounting bracket 205, the driver board 204, and the control board 202 are threaded together by long screws 201. The first mounting bracket 208, the power amplifier board 206, the second mounting bracket 205, the driver board 204, and the control board 202 form a stacked structure, all threaded together by long screws 201, thus forming the entire driver board assembly 2, facilitating the assembly and disassembly of the entire driver board assembly 2 from the mounting housing 1. Furthermore, the long screws 201 pass through the first support post 203 to connect the control board 202 to the driver board 204, the second mounting bracket 205, the power amplifier board 206, and the first mounting bracket 208 as a single unit, and the long screws 201 and the fixing screws 207 are staggered to avoid interference between them.

[0031] Further, as an optional embodiment of the present invention, the bleed plate assembly 3 is spaced apart from the mounting housing 1, and the bleed plate assembly 3 includes a bleed plate 301. A plurality of second support pillars 302 are provided between the bleed plate 301 and the mounting housing 1. One end of each second support pillar 302 is connected to the bleed plate 301, and the other end is connected to the bottom wall of the mounting housing 1. The second support pillar 302 has a segmented structure along the vertical direction, with one segment connected to the bleed plate 301 and the other segment connected to the bottom wall of the mounting housing 1, facilitating the fixing and disassembly of the bleed plate 301. Optionally, the bleed plate 301 is connected to the drive plate assembly 2, which has terminals, via two wires with solder tabs.

[0032] Optionally, in this invention, the capacitor on the capacitor assembly 12 is connected to the bleed plate assembly 3 by directly soldering the tail end of the wire to the bleed plate assembly 3.

[0033] Furthermore, as an optional embodiment of the present invention, the mounting housing 1 is connected to the drive board assembly 2, the bleeder plate assembly 3, and the capacitor assembly 12 respectively by screws from the outside to the inside thread. To facilitate the disassembly and assembly of the components in the servo controller, the drive board assembly 2, the bleeder plate assembly 3, and the capacitor assembly 12 are connected by screws from the outside to the inside thread. When disassembly and assembly are required, the threads can be removed from the outside of the mounting housing 1, and after the end cover is removed, the drive board assembly 2, the bleeder plate assembly 3, and the capacitor assembly 12 can be directly taken out.

[0034] Optionally, the servo controller of the present invention, which is easy to disassemble and assemble, can be installed into the mounting housing 1 after the drive board assembly 2, the discharge board assembly 3 and the capacitor assembly 12 have been connected and debugged.

[0035] Furthermore, as an optional embodiment of the present invention, the side wall of the mounting housing 1 is further provided with a first control signal output connector 4, a second control signal output connector 5, a first power output connector 6, a second power output connector 8, a control power supply input connector 9, a power supply input connector 10, and a signal input connector 11. All of these connectors are connected to the drive board assembly 2 via mounting interfaces. In this invention, all connectors for external interaction are located on one side wall of the mounting housing 1, facilitating information exchange between the servo controller and external devices. Additionally, the fact that all connectors are located on a single side wall makes it easier for the connectors to connect to the drive board assembly 2, reducing the possibility of wiring misalignment.

[0036] Optionally, the first control signal output connector 4, the second control signal output connector 5, the control power input connector 9, and the signal input connector 11 are soldered to the drive board assembly 2 via wires. After being connected to the drive board assembly 2, the first control signal output connector 4, the second control signal output connector 5, the control power input connector 9, and the signal input connector 11 are fixed to the mounting housing 1 with screws.

[0037] Furthermore, as an optional embodiment of the present invention, an adapter bracket 7 is also provided at the mounting interface. The adapter bracket 7 is fixed to the side wall of the mounting housing 1, and both the first power output connector 6 and the second power output connector 8 are connected to the mounting interface through the adapter bracket 7. The first power output connector 6 and the second power output connector 8 need to be fixed with multiple screws. To ensure the stable installation of the first power output connector 6 and the second power output connector 8 on the mounting housing 1, they are connected and fixed through an adapter. First, the adapter bracket 7 is fixed to the mounting housing 1, and then the first power output connector 6 and the second power output connector 8 are respectively fixed to the adapter bracket 7.
