The terminal board 40 is connected to the main board 30, the driving board 20 and the motor through cables. Therefore, the terminal board 40 is arranged outside the housing 10 and is separated from the housing 10, so that the user can adjust its position according to the wiring requirements, thereby improving the flexibility and convenience of wiring.

[0037] Combination Figure 1-Figure 2 , Figure 4-Figure 6 As shown, in one embodiment of the utility model, a plurality of connection holes 132 are opened on one side of the housing 10, a first signal connection terminal 21 is provided on one side of the driving board 20, a second signal connection terminal 31 is provided on one side of the main board 30, and a plurality of third signal connection terminals 41 are provided on the surface of the terminal board 40.

[0038] In this embodiment, the first signal connection terminal 21 and the second signal connection terminal 31 are designed to correspond to the position of the connection hole 132, and have the same shape and size, so that the first signal connection terminal 21 and the second signal connection terminal 31 can be quickly identified and connected with the corresponding connection hole 132, reducing the possibility of wiring errors. The connection holes 132 are distributed on one side of the housing 10 to form an array arrangement to meet the wiring requirements in different directions.

[0039] Furthermore, both sides of the housing 10 are provided with connection holes 132, and a communication connection terminal is provided on one side of the mainboard 30 away from the second signal connection terminal 31, and the communication connection terminal is exposed in the connection hole 132 and is used to connect an external control unit, such as a host, a control machine, etc., so that the operator can send instructions to the mainboard 30 through the host, and control the driving board 20 through the mainboard 30 to drive the motor to move.

[0040] Furthermore, the number and layout of the third signal connection terminals 41 are optimized according to the specific requirements of the motor and the control system. Figure 4 As shown, the third signal connection terminal 41 for connecting the first signal connection terminal 21 is arranged on one side of the terminal board 40 and is arranged at intervals parallel to the width direction of the terminal board 40 to facilitate connection with the drive board 20; the third signal connection terminal 41 for connecting the second signal connection terminal 31 is large in size, so it is arranged in the middle of the terminal board 40 to provide sufficient connection space for the cable; the third signal connection terminal 41 for connecting the motor includes a power supply port, an X-axis power port, a Y-axis power port, a Z-axis power port, and an XYZ-axis encoder connection port. The XYZ-axis encoder connection port is long, so it is designed to be the periphery of the terminal board 40, and the power supply port, X-axis power port, Y-axis power port, and Z-axis power port are small in size, so they are designed in the gap in the middle of the terminal board 40. The above arrangement design of multiple third signal connection terminals 41 improves the convenience of cable connection and the compactness of the structural arrangement.

[0041] Combination Figure 1-Figure 2 , Figure 4-Figure 6 As shown, in one embodiment of the present utility model, the first signal connection terminal 21, the second signal connection terminal 31 and the third signal connection terminal 41 are all provided with a plug interface, and the cable is plug-connected with the driver board 20, the main board 30 and the terminal board 40 through the plug interface;

[0045] Combination Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the driving board 20 and the main board 30 are arranged in parallel and spaced apart in the housing 10 , and the driving board 20 and the main board 30 are communicatively connected via a pin header.

[0046] In this embodiment, the drive board 20 and the main board 30 are arranged in parallel with each other at an interval, and the two are connected by a pin header, so that the layout of the drive board 20 and the main board 30 is more compact, so as to reduce space occupation and improve the communication efficiency between components. It can be understood that one of the drive board 20 and the main board 30 is provided with a pin header, and the other is provided with a slot, and the communication connection between the drive board 20 and the main board 30 is achieved by inserting the pin header into the slot. The pin header adopts a gold plating process to improve the antioxidant ability and the stability of signal transmission. In addition, the length of the pin header connection is shorter than that of the cable to reduce electromagnetic interference (EMI) and improve the integrity of signal transmission.

[0047] Furthermore, a limiting groove is provided on the inner wall of the outer shell 10, and after the main board 30 is connected to the driving board 20, it is placed in the outer shell 10, and the outer edge of the main board 30 is limited in the limiting groove, so that the main board 30 and the driving board 20 are stably arranged in the outer shell 10, reducing the influence of vibration on the signal transmission of the main board 30 and the driving board 20.

[0048] Combination Figure 1-Figure 2 , Figure 5-Figure 6As shown, in one embodiment of the present invention, the housing 10 includes a rear housing 11, a cover 12 and two side panels 13, the cover 12 is disposed on the top of the rear housing 11, and the two side panels 13 are respectively disposed on both sides of the rear housing 11, and the rear housing 11, the cover 12 and the two side panels 13 enclose the housing 10;

[0049] The side of the two side plates 13 away from the cover 12 is bent to form a handle 131, and the handle 131 is bent in a direction away from the rear shell 11. The handles 131 on the two side plates 13 are used to install and fix the housing 10, so that the stepping drive control device 1 has a horizontal installation mode in which the two handles 131 and the side of the rear shell 11 away from the cover 12 are exposed to the outside;

[0050] Alternatively, the two side panels 13 have different sizes, and the outer periphery of the larger side panel 13 extends to the outside of the rear shell 11 and the face cover 12 to form a handle 131, which is used to install and fix the outer shell 10, so that the stepping drive control device 1 has a card-insertion installation mode in which the larger side panel 13 is exposed to the outside.

[0051] In this embodiment, the rear shell 11, the front cover 12 and the two side plates 13 of the housing 10 adopt a modular design, which is convenient for assembly and disassembly. The rear shell 11 includes a bottom wall and two oppositely arranged side walls, the two side plates 13 are respectively connected between the two side walls, and the front cover 12 is arranged at the upper end of the rear shell 11, thereby enclosing the housing 10. A convex protrusion 121 is convexly provided on the side of the front cover 12 facing the rear shell 11, and a groove is formed on the end surface of the side wall of the rear shell 11 facing the front cover 12, and the convex protrusion 121 is clamped in the groove so that the front cover 12 and the rear shell 11 can be detachably connected. The design of the handle 131 is convenient for the user to grasp, so as to facilitate the housing 10 to be installed in the installation hole of the control cabinet, or to remove the housing 10 from the control cabinet.

[0052] In one example, the side of the two side plates 13 away from the cover 12 is bent at 90 degrees to form a handle 131, and the handle 131 is parallel to the outer side of the rear shell 11. In this case, the stepping drive control device 1 adopts a horizontal installation mode. The shape of the shell 10 and the position of the handle 131 are as follows: Figure 1 As shown, the side of the housing 10 provided with the cover 12 is first inserted into the mounting hole of the control cabinet, and the housing 10 is inserted further until the handle 131 abuts against the outer surface of the control cabinet. The handle 131 is provided with a threaded connection hole 132, and the handle 131 is mounted on the control cabinet using a threaded connection member, thus completing the installation of the stepping drive control device 1.

[0053] In another example, the side plate 13 of the two side plates 13 that is away from the first signal connection terminal 21 of the driving board 20 is larger in size, and the periphery of the larger side plate 13 extends to the outside of the rear shell 11 and the cover 12, and forms a handle 131, and the smaller side plate 13 is flush with the rear shell 11 and the cover 12. In this case, the stepping drive control device 1 adopts a plug-in installation mode, and the shape of the housing 10 and the position of the handle 131 are as shown in FIG. Figure 5 As shown, the side of the housing 10 provided with the smaller side panel 13 is first inserted into the mounting hole of the control cabinet, and then the housing 10 is inserted further until the larger side panel 13 abuts against the outer surface of the control cabinet and is connected to the control cabinet.

[0054] Therefore, the housing 10 of the stepper drive control device 1 has two different installation options, and the installation flexibility with the control cabinet is higher. In addition, the bending design of the handle 131 also provides a certain degree of anti-collision protection, reducing the damage of the housing 10 during transportation and use.

[0055] Combination Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment of the utility model, the stepping drive control device 1 also includes a heat sink 50, which is arranged on the bottom wall of the rear shell 11 relative to the surface cover 12, and the driving plate 20, the heat sink 50 and the bottom wall of the rear shell 11 are all provided with threaded holes, and the driving plate 20, the heat sink 50 and the bottom wall of the rear shell 11 are connected in sequence by threaded connectors.

[0056] In this embodiment, the heat sink 50 can be silicone cloth, thermal grease, etc. The heat sink 50 is in the shape of a sheet and has good thermal conductivity and ductility. Therefore, the heat sink 50 can increase the thermal contact area with the driving board 20 to improve the heat dissipation efficiency. The driving board 20 and the heat sink 50 are fastened to the bottom wall of the housing 10 through threaded connectors, which further increases the contact area between the driving board 20 and the heat sink 50, and between the heat sink 50 and the bottom wall, thereby improving the heat dissipation efficiency. The threaded connector can be a screw, a bolt, etc. The size and position of the threaded hole are precisely matched according to the thermal expansion coefficient of the heat sink 50 and the rear housing 11 to ensure good contact at different temperatures.

[0057] Combination Figure 2-Figure 3 , Figure 6-Figure 7 As shown, in one embodiment of the present invention, a plurality of heat dissipation fins 111 are protruding from the bottom wall, a mounting plate 112 parallel to the bottom wall is disposed on the surface of the heat dissipation fins 111 , and the heat dissipation fins 50 are disposed on the mounting plate 112 .

[0058] In this embodiment, a plurality of heat dissipation fins 111 are arranged in parallel and spaced apart to increase the heat dissipation area, and the design of the heat dissipation fins 111 adopts aerodynamic principles to optimize air flow and enhance the heat dissipation effect between the drive board 20 and the bottom wall of the housing 10. The mounting plate 112 is parallel to the bottom wall to provide a stable support for the drive board 20 and the heat dissipation fins 50.

[0059] Combination Figure 2-Figure 3 , Figure 6-Figure 7 As shown, in one embodiment of the utility model, a avoidance groove 113 is provided on the side of the mounting plate 112 and the heat sink 111 facing the driving plate 20, and a first signal connection terminal 21 for connecting to the terminal board 40 is provided on the side of the driving plate 20 facing the bottom wall.

The driving plate 20 is fitted with the heat sink 50, and the first signal connection terminal 21 is embedded in the avoidance groove 113.

[0060] In this embodiment, the design of the avoidance groove 113 takes into account the space limitation of the driving board 20, ensuring that the first signal connection terminal 21 can be smoothly embedded without affecting other components. The shape of the avoidance groove 113 is precisely matched with the first signal connection terminal 21 to ensure the reliability and long-term stability of the electrical connection. By providing the avoidance groove 113 to avoid the first signal connection terminal 21 of the driving board 20, the compactness of the structure of the stepping drive control device 1 is improved.

[0061] In one embodiment of the present invention, the shell 10 is made of aluminum alloy. The shell 10 made of aluminum alloy is not only light in weight, but also has good heat dissipation performance and corrosion resistance, and is suitable for use in various environmental conditions. The surface of the shell 10 is anodized or sandblasted to improve the appearance and durability of the shell 10.

[0062] In one embodiment of the utility model, the drive board 20 is a four-axis driver, and the main board 30 is a PLC controller. The drive board 20 is designed as a four-axis driver, which can independently control the motion parameters of each axis of the motor, such as speed, acceleration and position.
