[0002] A stepper motor controller is a device used to control the operation of a stepper motor. With the development of technology, in order to improve work efficiency, stepper motor controllers have gradually evolved from being able to control only one stepper motor at a time to being able to control multiple stepper motors at a time. In order to enable a single stepper motor controller to better control multiple stepper motors, the number of circuit boards inside the stepper motor controller has also increased.

In order to improve the compactness of the arrangement of the circuit boards in the circuit board assembly, the multiple circuit boards in the circuit board assembly are usually arranged at intervals along a preset direction.

[0004] However, the specifications and sizes of the circuit boards in the circuit board group are different, and various electrical components need to be installed on the surface of the circuit boards. If the circuit boards are simply arranged at intervals along a preset direction, a large enough clearance space needs to be left between two adjacent circuit boards, which makes the structure of the circuit board group less compact.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] The following is for reference. Figures 1 to 5 The stepper motor controller of the first aspect of this application will be described in detail.

[0034] refer to Figure 1 and Figure 2 The stepper motor controller according to the first aspect of the present invention includes a housing 100 and a circuit board assembly 200.

[0035] A receiving cavity 120 is formed within the outer casing 100; a circuit board assembly 200 is disposed within the receiving cavity 120. The circuit board assembly 200 includes a main control board 210, an adapter board 220, an interface board 230, and a driver board assembly 240. The main control board 210, the adapter board 220, and the driver board assembly 240 are stacked sequentially along a preset direction. The driver board assembly 240 includes a plurality of driver boards 241 stacked along the preset direction. A portion of the periphery of the driver board 241 and the adapter board 220 define a receiving cavity. In area 201, interface board 230 is located within the receiving area 201, and the peripheral edge of interface board 230 is inserted into the surface of adapter board 220. Main control board 210, interface board 230 and drive board 241 are all electrically connected to adapter board 220. Main control board 210 is provided with multiple communication interfaces for communication with external devices. Interface board 230 is provided with encoder interface 231. Drive board 241 is provided with stepper motor wire connector 241a and drive power connector 241b.

[0036] For example, such as Figure 1 , Figure 2 and Figure 5 As shown, the preset direction is left and right. The stepper motor controller includes a housing 100 and a circuit board assembly 200. A receiving cavity 120 is formed inside the housing 100, and the circuit board assembly 200 is disposed inside the receiving cavity 120. The circuit board assembly 200 includes a main control board 210, an adapter board 220, an interface board 230, and a driver board assembly 240. The main control board 210, the adapter board 220, and the driver board assembly 240 are stacked sequentially from left to right. The driver board assembly 240 includes multiple driver boards 241 stacked in the left and right direction. The front peripheral side of the driver board 241, the rear peripheral side of the driver board 241, and the right side of the adapter board 220 together limit the... The main control board 210 has a receiving area 201, and an interface board 230 is disposed in the receiving area 201. The interface board 230 is located in front of the drive board 241. The left edge of the interface board 230 is inserted into the surface of the adapter board 220. The left side of the main control board 210 is provided with multiple communication interfaces for communication with external devices. The front side of the interface board 230 is provided with an encoder interface 231. The right side of the drive board 241 is provided with a stepper motor wire connector 241a and a drive power connector 241b. The main control board 210, the interface board 230 and the drive board 241 are electrically connected to the adapter board 220.

[0037] It is understandable that by placing the interface board 230 within the receiving area 201, the size of the circuit board assembly 200 in the left-right direction can be reduced, and the space in the receiving area 201 can be fully utilized, making the overall structure of the circuit board assembly 200 of the stepper motor controller of this utility model more compact.

[0038] It is understandable that, since each driver board 241 is provided with a drive power connector 241b, each driver board 241 can be connected to a drive power supply independently. When using the stepper motor controller of this utility model, the operator can select the number of drive power supplies connected to the stepper motor controller of this utility model according to the voltage of the stepper motor. Thus, the stepper motor controller of this utility model can be adapted to stepper motors of various specifications.

[0039] It is understandable that the encoder interface 231 is relatively large. Since the interface board 230 is located in the receiving area 201, by setting the encoder interface 231 on the interface board 230, the influence of the encoder interface 231 on the size of the circuit board assembly 200 in the preset direction can be reduced, so that the size of the circuit board assembly 200 of the stepper motor controller of this utility model in the preset direction can be set to be smaller.

[0040] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 The main control board 210 has multiple communication interfaces including a gigabit Ethernet port 211, an EtherCAT expansion port 212, a USB port 213, an HDMI interface 214, an SD card slot 215, and a WIFI antenna 216; the adapter board 220 is equipped with a power supply connector 221, an input IO connector 222, an output IO connector 223, and a serial port connector 224; the interface board 230 is also equipped with IO indicator lights and a light guide column 232.

[0041] In some embodiments of this utility model, reference is made to Figure 2 The stepper motor controller also includes a connection structure 300, which extends along a preset direction and passes through the main control board 210, the adapter board 220 and each drive board 241 in sequence. Both ends of the connection structure 300 in the preset direction are connected to the housing 100.

[0042] Furthermore, when assembling the stepper motor controller of this utility model, the operator can arrange the main control board 210, the adapter board 220 and each drive board 241 in sequence along a preset direction, and then use the connecting structure 300 to pass through the main control board 210, the adapter board 220 and each drive board 241 in sequence to realize the connection between the main control board 210, the adapter board 220 and each drive board 241. Next, the operator can place the interface board 230 in the receiving area 201 and insert the peripheral edge of the interface board 230 into the adapter board 220. Then, the operator can install the assembled circuit board group 200 in the receiving cavity 120 of the housing 100, thereby completing the assembly of the stepper motor controller of this utility model.

[0043] It is understandable that the connection structure 300 allows the circuit board assembly 200 to form a whole. The main control board 210, the adapter board 220 and each drive board 241 do not need to be individually connected to the cavity wall of the receiving cavity 120. The circuit board assembly 200 can be installed as a whole in the receiving cavity 120 of the housing 100 after assembly. The assembly process of the stepper motor controller of this utility model is simpler and more convenient.

[0044] In some embodiments of this utility model, the connection structure 300 includes a plurality of connectors 310 that are threaded together in sequence along a preset direction. The main control board 210, the adapter board 220 and each drive board 241 are all provided with connectors 310.

[0045] For example, such as Figure 2 and Figure 3 As shown, the connection structure 300 includes multiple connectors 310 that are connected end to end in the left-right direction by threads. A connector 310 is respectively passed through the main control board 210, the adapter board 220 and each drive board 241.

[0046] It is understandable that when assembling the stepper motor driver of this utility model, the operator can first install a connector 310 on the main control board 210, the adapter board 220 and each driver board 241 respectively. Then, the operator can connect the connectors 310 end to end in sequence and insert the interface board 230 on the adapter board 220 to complete the assembly of the circuit board group 200.

[0047] Understandably, since the connection structure 300 includes multiple connectors 310 that are threaded together sequentially along a preset direction, and the main control board 210, the adapter board 220, and each drive board 241 are all equipped with connectors 310, when the operator removes a circuit board from the main control board 210, the adapter board 220, and each drive board 241, they only need to remove the connector 310 corresponding to the circuit board from the connection structure 300, which is simple and convenient.

[0048] In some embodiments of this utility model, the connector 310 includes a head 311 and a rod 312. Between any two adjacent connectors 310, the rod 312 of one connector 310 is threadedly connected to the head 311 of the other connector 310, and a clamping area 301 is formed between any two adjacent heads 311. The main control board 210, the adapter board 220 and each drive board 241 are respectively clamped in a clamping area 301.

[0049] For example, such as Figure 3As shown, the connector 310 extends in the left-right direction. The connector 310 includes a head 311 and a rod 312 connected together. In the same connector 310, the right end of the rod 312 is connected to the left end of the head 311, and the cross-sectional dimension of the rod 312 is smaller than the cross-sectional dimension of the head 311. In any two adjacent connectors 310, the rod 312 of the connector 310 on the right side is threadedly connected to the head 311 of the connector 310 on the left side. A clamping area 301 is formed between the heads 311 of any two adjacent connectors 310. The main control board 210, the adapter board 220 and each drive board 241 are clamped in a clamping area 301.

[0050] Taking the connection between the main control board 210 and the connecting structure 300 as an example, the rod 312 of the connector 310 passes through the main control board 210 and is threadedly connected to the head 311 of another connector 310. At this time, the main control board 210 is located in the clamping area 301 formed by the heads 311 of the two connectors 310, and the heads 311 of the two connectors 310 cooperate to clamp the main control board 210.

[0051] Understandably, the clamping area 301 allows the main control board 210, adapter board 220, and each drive board 241 to be connected to the connecting structure 300. The two heads 311 adjacent to the main control board 210 can clamp and fix the main control board 210, the two heads 311 adjacent to the adapter board 220 can clamp and fix the adapter board 220, and the two heads 311 adjacent to the drive board 241 can clamp and fix the drive board 241. Therefore, the installation of the main control board 210, adapter board 220, and each drive board 241 on the connecting structure 300 is more secure and stable.

[0052] In some embodiments of this utility model, multiple connection structures 300 are provided, and the multiple connection structures 300 are distributed at intervals along the edge of the drive plate 241.

[0053] It is understandable that by setting multiple connection structures 300, the overall structure of the circuit board assembly 200 can have higher strength and higher stability.

[0054] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The outer shell 100 includes a plurality of shells 110 sequentially spliced ​​along a preset direction, and the plurality of shells 110 together define a receiving cavity 120.

[0055] It is understandable that by setting the outer shell 100 as a splicing of multiple shells 110, each shell 110 can be manufactured using an integral molding process, and the manufacturing difficulty of a single shell 110 is relatively low, thereby reducing the overall manufacturing difficulty of the outer shell 100.

[0056] It should be noted that, since the main control board 210, the adapter board 220 and each drive board 241 are stacked sequentially along a preset direction, as the stepper motor controller of this utility model works, a large amount of heat will accumulate between the main control board 210 and the adapter board 220, between the adapter board 220 and the drive board 241, and between any two adjacent drive boards 241. If this heat is not dissipated in time, the temperature of the circuit board assembly 200 will rise, thereby damaging the circuit board assembly 200.

[0057] Based on the above problems, in some embodiments of this utility model, the stepper motor controller further includes at least one cooling fan 400 disposed in the receiving cavity 120. Heat dissipation channels are formed between the main control board 210 and the adapter board 220, between the adapter board 220 and the drive board group 240, and between any two adjacent drive boards 241. Each heat dissipation channel is connected to the air outlet of at least one cooling fan 400.

[0058] For example, such as Figure 2 As shown, the cavity 120 is equipped with two cooling fans 400, which are arranged in the left-right direction. Both cooling fans 400 are located below the circuit board assembly 200 and are used to provide upward airflow.

[0059] It is understood that in the stepper motor controller of this utility model, by setting a cooling fan 400, the cooling fan 400 can blow airflow into the heat dissipation channel to remove the heat in the heat dissipation channel, thereby cooling the circuit board assembly 200 and extending the service life of the circuit board assembly 200.

[0060] In a further embodiment of the present invention, the cavity wall of the receiving cavity 120 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is directly opposite the air inlet of the cooling fan 400, and the air outlet 102 is directly opposite the air outlet of the cooling fan 400 and is connected to the heat dissipation channel.

[0061] For example, such as Figure 2 As shown, an air inlet 101 is provided on the lower cavity wall of the receiving cavity 120, and an air outlet 102 is provided on the upper cavity wall of the receiving cavity 120.

[0062] Understandably, under the action of the cooling fan 400, air enters the heat dissipation channel through the air inlet 101 and is discharged through the air outlet 102 to carry away the heat in the heat dissipation channel.

[0063] In some embodiments of this utility model, reference is made to Figure 4 Both the main control board 210 and the adapter board 220 have clearance notches 210a on their periphery to allow the cooling fan 400 to pass.

[0064] It is understandable that the main control board 210 and the adapter board 220 are both larger than the drive board 241. By opening clearance notches 210a on the periphery of the main control board 210 and the adapter board 220, the cooling fan 400 located directly below the main control board 210 and the adapter board 220 can be partially accommodated in the clearance notches 210a, so that each cooling fan 400 in the accommodating cavity 120 can be located on the same horizontal plane.

[0065] The automation equipment provided according to the second aspect of the present invention includes the stepper motor controller provided in the first aspect of the present invention.

[0066] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
