Description

Technical Field

[0001] This utility model belongs to the technical field of motor driver communication devices, specifically relating to a closed-loop stepper driver bus communication device. Background Technology

[0002] A closed-loop stepper driver is a common type of motor driver. It precisely controls the rotation of a stepper motor by controlling the current, achieving accurate positioning and motion control. During use, a closed-loop stepper driver typically communicates with other host computer devices via a bus communication device. Other host computer devices, such as PLCs or motion controllers, send motion control commands to the closed-loop stepper driver through the bus communication device, such as target position, speed, and acceleration. The driver then feeds back its own status information, such as current position, running speed, and fault alarms, to the host computer.

[0003] Bus communication devices generally consist of two parts: hardware and software. The hardware includes communication interface circuits, such as RS485 interface chips, CAN controllers and transceivers, and data interfaces such as terminal blocks, which are used to realize physical layer signal transmission and electrical connection. The software includes a communication protocol stack, which is used to realize functions such as data packing and unpacking, transmission control, error detection and handling, and ensure the accuracy of communication. When the bus communication device is installed on the housing of the closed-loop stepper driver, the bus communication device is equipped with terminal blocks. The terminal blocks are connected to the data lines of the closed-loop stepper driver. The terminal blocks on the bus communication device are exposed and there is no design to shield or protect the ends of the terminal blocks and data lines. The terminal blocks and the connected data lines are susceptible to external interference, which can affect the smoothness of the data connection.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a closed-loop stepper driver bus communication device, including a bus communicator 1 electrically connected to the closed-loop stepper driver. A terminal block 2 is fixedly connected to one side of the bus communicator 1 by screws. The bus communicator 1 is fixedly connected to the housing of a single closed-loop stepper driver by screws. A data line connects the bus communicator 1 and the closed-loop stepper driver, with one end of the data line connected to the terminal block 2. When the bus communicator 1 is connected to multiple closed-loop stepper drivers, different data lines are connected to the terminal block 2 in parallel. The number of closed-loop stepper drivers connected to the line communicator 1 is designed according to actual conditions; the protective components for the data line include a fixing plate 3 fixed to the bus communicator 1 by screws, a side plate 31 on the side of the vertical fixing plate 3, a fixing partition 5 in the middle of the vertical fixing plate 3, and a cover plate 4 connected to the side plate 31 by hinges. The inner surface of the fixing partition 5 is provided with equally spaced partition plates 51, the surface of the fixing plate 3 is provided with a blocking plate 32, and the side of the cover plate 4 is provided with a vertical end plate 41 and a hand-tightening locking screw 42. The fixing plate 3 and the side plate 31 Together with the cover plate 4, they form a protective shield to cover and protect the terminal block 2 and data cables, preventing the ends of the terminal block 2 and data cables from being exposed and interfered with by external factors. The fixed partition plate 5 and the partition plate 51 serve to separate the data cables, and the blocking plate 32 also serves to block the data cable bundle, preventing the data cables from being scattered and affecting the corresponding connection between the data cables and the terminal block 2. The protective components include a heat sink 6 fixed to the side of the cover plate 4 by screws, a heat-conducting copper pillar 61 perpendicular to the heat sink 6, a first rubber pad 8 sleeved on the outside of the heat-conducting copper pillar 61, and a protective layer that is attached to the surface of the first rubber pad 8. The shell 7, the second rubber pad 9 embedded inside the protective shell 7, the heat sink 6, the heat-conducting copper pillar 61, and the protective shell 7 are all made of metal materials with high thermal conductivity, such as copper and aluminum. The first rubber pad 8 and the second rubber pad 9 are made of rubber material. When the cover plate 4 is attached to the side plate 31, the heat sink 6 contacts the shell surface of the bus communicator 1. By utilizing thermal conductivity, heat is conducted from high temperature to low temperature to achieve the purpose of heat dissipation. The first rubber pad 8, the second rubber pad 9, and the protective shell 7 also play a protective role to prevent the bus communicator 1 from being bumped by other objects in case of accidents.

[0026] In this embodiment, the side plate 31 has an "L" shaped structure. The side plate 31, the baffle plate 32, and the fixed partition plate 5 are flush with the surface of the fixed plate 3. When the cover plate 4 is closed, the cover plate 4 is in contact with the side plate 31, the baffle plate 32, and the fixed partition plate 5.

The wire groove a and wire groove b facilitate the passage of the data cable and do not affect the connection between the data cable and the terminal block 2.

[0028] In this embodiment, the fixing plate 3 has a screw hole near the corner that mates with the hand-tightening screw 42. The surface of the cover plate 4 facing away from the fixing plate 3 is flush with the surface of the bus communicator 1. Under the locking action of the hand-tightening screw 42, the cover plate 4 is firmly connected to the fixing plate 3.

[0029] In this embodiment, the heat sink 6 and the protective shell 7 are perpendicular to each other. The first rubber pad 8 is a long, three-dimensional strip with the same width as the heat sink 6. The first rubber pad 8 has a circular hole through which the heat-conducting copper pillar 61 passes. The protective shell 7 and the second rubber pad 9 are both long, three-dimensional strips, and the side of the protective shell 7 facing away from the first rubber pad 8 is open. The first rubber pad 8, the second rubber pad 9, and the protective shell 7 also serve a protective function to prevent the bus communicator 1 from being bumped by other objects in case of accidents. When the cover plate 4 is attached to the side plate 31, the heat sink 6 contacts the surface of the casing of the bus communicator 1. By utilizing thermal conductivity, heat is conducted from high temperature to low temperature, thus achieving the purpose of heat dissipation.

[0030] Working principle and usage process of this utility model:

[0031] When the bus communicator 1 is used for communication and control of the closed-loop stepper driver, the terminal block 2 on the bus communicator 1 is connected to the data line.

[0032] When connecting the data cable, one end of the data cable is located in the space between the fixed plate 3 and the cover plate 4, and the other end of the data cable passes through the wire groove a on the fixed partition 5 and is connected to the socket on the corresponding terminal block 2.

[0033] When there are many data cables, different data cables are separated by the separator 51. In addition, the baffle 32 also blocks the separated data cables to prevent them from being scattered.

[0034] When the cover plate 4 is attached to the fixing plate 3, the fixing plate 3, the side plate 31 and the cover plate 4 form a protective shield to shield and protect the terminal block 2 and the data cable, so as to prevent the terminals of the terminal block 2 and the data cable from being exposed and interfered with by external factors.

[0035] When the cover plate 4 is attached to the fixing plate 3, the heat sink 6 contacts the housing surface of the bus communicator 1. By utilizing thermal conductivity, heat is transferred from high temperature to low temperature, thus achieving the purpose of heat dissipation.

[0036] The first rubber pad 8, the second rubber pad 9, and the protective shell 7 also serve a protective function, preventing the bus communicator 1 from being bumped or knocked by other objects in case of an accident.

[0037] In summary: The bus communication device has a design to shield and protect the terminals 2 and the ends of the data lines. The fixing plate 3, the side plate 31, and the cover plate 4 form a protective shield to shield and protect the terminals 2 and the data lines, preventing the terminals 2 and the ends of the data lines from being exposed and interfered with by external factors. The first rubber pad 8, the second rubber pad 9, and the protective shell 7 protect the bus communicator 1, preventing the bus communicator 1 from being bumped by other objects in case of accidents.
