Description

Technical Field

[0001] The utility model belongs to the technical field of motors, in particular to an integrated stepping motor driver. Background Art

[0002] With the rapid development of industrial automation and intelligent manufacturing technologies, stepper motors have been widely used as actuators in a variety of fields, including automated production lines, precision instruments, and medical equipment. Traditional stepper motor systems typically include independent motors, drivers, and controllers. This separate design not only increases system complexity but also limits overall performance, particularly in terms of complex installation, high maintenance costs, and large space requirements. Against this backdrop, integrated stepper motor drivers have emerged, representing a major innovation in motor technology. Patent publication number CN221487526U discloses an integrated stepper motor driver, comprising a stepper motor driver and a stepper motor. The stepper motor driver has a mounting structure disposed on its top, comprising a collar with two sides having slots formed thereon. Bars are fixedly mounted on both sides of the stepper motor's end, with the cross-sectional diameter of the bar matching the width of the slot. A locking mechanism is disposed on the top of the stepper motor driver, comprising a clamping block, the bottom of which is rotatably connected to the top of the stepper motor driver. A torsion spring is installed at the connection between the clamping block and the stepper motor driver. During the process of implementing the present invention, the inventors discovered that there are at least the following problems in the prior art.

[0003] In the current prior art, when a stepper motor is in use, it is easy for the power connection to become loose, causing the stepper driver to not work properly or to work unstably.

[0004] Therefore, an integrated stepper motor driver is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the stepper motor driver cannot work normally or works unstably due to loose power connection during use, an integrated stepper motor driver is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: an integrated stepper motor driver according to the present invention comprises a motor body and a drive protection mechanism assembled on one side of the motor body, an encoder is mounted inside the drive protection mechanism, mounting seats are mounted at the four corners of the drive protection mechanism outside the encoder, one side of the mounting seat is connected to a drive control module via a mounting bolt, a damping ring is sleeved around the mounting bolt on the other side of the drive control module, a power connection box is mounted on the top of the drive protection mechanism, and an anti-drop mechanism is movably mounted on one side of the power connection box;

[0007] The anti-falling mechanism includes a flip plate, a lower pressure plate and a line clamp. The flip plate is rotatably installed on one side of the power connection box, the lower pressure plate is movably installed on the top of the flip plate, and the line clamp is installed on the other side of the lower pressure plate.

[0008] Preferably, the anti-drop mechanism further includes a pull rod and a first spring. The bottom of the lower pressure plate is mounted with several pull rods extending into the interior of the flip plate, and the first spring is sheathed around the outer periphery of the pull rods. During use, the lower pressure plate can pull the pull rods upward to secure power connectors of varying sizes. The movement of the pull rods compresses the first spring, leveraging its elasticity to increase the pressure applied by the line clamp to the power connector, preventing it from loosening.

[0009] Preferably, the anti-drop mechanism further includes a second spring and a fixing seat, the fixing seat being mounted at both ends of the power connection box, and the fixing seat being rotationally connected to the flip plate via the second spring. During use, the second spring and the fixing seat can stretch the flip plate, preventing it from rotating and tipping over during use, thereby making the flip plate more stable.

[0010] Preferably, the drive protection mechanism includes an aluminum die-cast end cap, a connecting seat, and a connecting bolt. The connecting bolt is removably mounted on one side of the motor body. The four corners of the connecting bolt are connected to the motor body via the connecting seat, and the aluminum die-cast end cap is mounted on one side of the connecting bolt. The aluminum die-cast end cap enhances the device's anti-interference capabilities to adapt to complex working environments. The connecting seat is connected to the stepper motor box through the connecting bolt, completing the assembly of the motor body and the drive protection mechanism for easy maintenance.

[0011] Preferably, the drive protection mechanism further includes a heat dissipation fan and a heat dissipation window. The heat dissipation fan is mounted on one side of the interior of the aluminum die-cast end cover, and the heat dissipation window is mounted on one side of the aluminum die-cast end cover. When powered on, the heat dissipation fan can dissipate heat from the interior of the drive protection mechanism, thereby preventing the drive control module and encoder installed within the drive protection mechanism from overheating and damage during use. The heat dissipation window can facilitate the flow of air between the interior of the drive protection mechanism and the external environment.

[0012] Preferably, the motor body includes a stepper motor housing, an assembly base, and a transmission shaft. The stepper motor housing is mounted on the other side of the drive protection mechanism, the assembly base is mounted on the other side of the stepper motor housing, and the transmission shaft is mounted on the other side of the stepper motor housing through the assembly base. During operation, the stepper motor housing drives the transmission shaft to rotate, thereby achieving power transmission. The assembly base can be used to limit the position of the stepper motor housing.

[0013] Preferably, the drive control module is electrically connected to the stepper motor housing, the cooling fan, the power connection box, and the encoder via wires. After the power connection box is connected to an external power source, the drive control module can be used to control the stepper motor housing, the cooling fan, and the encoder for easy use.

[0014] Beneficial effects of the utility model:

[0015] The utility model provides an integrated stepper motor driver. By arranging an anti-falling mechanism, the external power supply connector connected to the power supply connection box can be pressed down and limited by using the anti-falling mechanism during use, so as to prevent the power supply connector from loosening and falling due to vibration generated during the operation of the motor body, so that the operation of the stepper driver is more stable. By arranging a damping ring between the mounting seat and the drive control module, the influence of the vibration generated by the motor body on the drive control module can be effectively reduced, thereby extending the service life.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Specific examples are given below.

[0027] See also Figures 1-6 The utility model provides an integrated stepper motor driver, comprising a motor body 1 and a drive protection mechanism 2 assembled on one side of the motor body 1, an encoder 9 being mounted inside the drive protection mechanism 2, mounting seats 8 being mounted at the four corners of the drive protection mechanism 2 outside the encoder 9, a drive control module 5 being connected to one side of the mounting seat 8 via a mounting bolt 6, a damping ring 7 being sleeved around the mounting bolt 6 on the other side of the drive control module 5, a power connection box 3 being mounted on the top of the drive protection mechanism 2, and an anti-falling mechanism 4 being movably mounted on one side of the power connection box 3;

[0028] The anti-falling mechanism 4 includes a flip plate 401, a lower pressing plate 402 and a line clamp 405. The flip plate 401 is rotatably installed on one side of the power connection box 3, the lower pressing plate 402 is movably installed on the top of the flip plate 401, and the line clamp 405 is installed on the other side of the lower pressing plate 402.

[0029] During operation, the motor body 1 is first installed in the specified position, and the power connection box 3 is used to connect it to the external power supply. After the connection, the flip plate 401 is rotated to rotate the lower pressure plate 402 to the interface on the power connection box 3, and then the line clamp 405 is used to clamp and limit the connected power line to avoid loose power. During the operation of the device, the encoder 9 monitors the rotation position of the motor body 1 in real time, and feeds this information back to the drive control module 5, so that the drive control module 5 can accurately know the current position of the motor body 1, thereby realizing precise control of the motor body 1, and using the drive protection mechanism 2 to wrap and protect the drive control module 5 and the encoder 9.

[0030] Further, such as Figure 6 As shown, the anti-drop mechanism 4 also includes a pull rod 403 and a first spring 404. The bottom of the lower pressure plate 402 is equipped with several pull rods 403 that extend into the interior of the flip plate 401, and the first spring 404 is sheathed around the pull rods 403. The flip plate 401 has a slot inside that accommodates the movement of the first spring 404. Specifically, when in use, the lower pressure plate 402 can pull the pull rod 403 upward to limit the position of power connectors of different sizes. During the movement of the pull rod 403, the first spring 404 is squeezed, and the elasticity of the first spring 404 increases the pressure applied by the line clamp 405 on the power connector to prevent it from loosening.

[0031] Further, such as Figure 6 As shown, the anti-fall mechanism 4 further includes a second spring 406 and a fixing seat 407. The fixing seat 407 is mounted at both ends of the power connection box 3. The fixing seat 407 is rotationally connected to the flip plate 401 via the second spring 406. The second spring 406 is at the same horizontal position as the rotation position of the bottom of the flip plate 401. Specifically, during use, the second spring 406 and the fixing seat 407 can stretch the flip plate 401, preventing the flip plate 401 from rotating and tipping over during use, thereby making the flip plate 401 more stable.

[0032] Further, such as Figure 2 and Figure 4 As shown, the drive protection mechanism 2 includes an aluminum die-cast end cap 201, a connecting seat 204, and a connecting bolt 205. The connecting bolt 205 is detachably mounted on one side of the motor body 1. The four corners of the connecting bolt 205 are connected to the motor body 1 via the connecting seat 204. The aluminum die-cast end cap 201 is mounted on one side of the connecting bolt 205. Specifically, the aluminum die-cast end cap 201 can enhance the device's anti-interference ability to adapt to complex working environments. The motor body 1 and the drive protection mechanism 2 are assembled by connecting the connecting seat 204 through the connecting bolt 205 and the stepper motor box 101, facilitating maintenance.

[0033] Further, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the drive protection mechanism 2 further includes a heat dissipation fan 202 and a heat dissipation window 203. The heat dissipation fan 202 is mounted on one side of the interior of the aluminum die-cast end cover 201, and the heat dissipation window 203 is mounted on one side of the aluminum die-cast end cover 201. Specifically, when powered on, the heat dissipation fan 202 can dissipate heat from the interior of the drive protection mechanism 2, thereby preventing the drive control module 5 and encoder 9 installed inside the drive protection mechanism 2 from overheating and damage during use. The heat dissipation window 203 can promote the flow of air between the interior of the drive protection mechanism 2 and the external environment.

[0034] Further, such as Figure 2 As shown, the motor body 1 includes a stepper motor case 101, an assembly base 102, and a transmission shaft 103. The stepper motor case 101 is mounted on the other side of the drive protection mechanism 2, and the assembly base 102 is mounted on the other side of the stepper motor case 101. The transmission shaft 103 is mounted on the other side of the stepper motor case 101 through the assembly base 102. Specifically, during the operation of the stepper motor case 101, the transmission shaft 103 is driven to rotate, thereby realizing power transmission. The assembly base 102 can be used to limit the position of the stepper motor case 101.

[0035] Further, such as Figures 1-6 As shown, the drive control module 5 is electrically connected to the stepper motor box 101, the cooling fan 202, the power connection box 3, and the encoder 9 via wires. Specifically, after the power connection box 3 is connected to an external power source, the drive control module 5 can be used to control the stepper motor box 101, the cooling fan 202, and the encoder 9 for easy use.

[0036] Working principle: When in use, the device is installed in the designated position using the assembly seat 102, and the power connection box 3 is used to connect to the external power supply. After the connection, the flip plate 401 is rotated to rotate the lower pressure plate 402 to the interface on the power connection box 3, and the connected power line is clamped and limited by the line clamp 405. The pull rod 403 is pulled upward to move, so that power connectors of different sizes can be limited. During the movement of the pull rod 403, the first spring 404 is squeezed, and the elasticity of the first spring 404 is used to increase the pressure applied by the line clamp 405 on the power line connector. During the operation of the device, the encoder 9 monitors the rotation position of the motor body 1 in real time and feeds this information back to the drive control module 5, so that the drive control module 5 can accurately know the current position of the motor body 1, thereby achieving precise control of the motor body 1. When the heat dissipation fan 202 is energized, it can dissipate heat inside the drive protection mechanism 2 to prevent the drive control module 5 and encoder 9 installed inside the drive protection mechanism 2 from overheating and damage during use. The heat dissipation window 203 can promote the flow of air between the inside of the drive protection mechanism 2 and the external environment.
