Description

Technical Field

[0001] The utility model relates to the technical field related to driving devices, in particular to a motor driving device. Background Art

[0002] A motor driver is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called the "step angle") in the set direction. Its rotation is performed step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, thereby achieving accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation and positioning.

[0003] Due to the large number of internal circuits, there are many integrated circuit components, so a lot of heat will be generated during operation. If the heat dissipation effect is not good, it is easy to cause damage to the internal components and affect their normal operation. However, the motor drive devices currently used are mostly designed with holes on the shell surface, and their heat dissipation effect is general. If the working environment is highly airtight, the heat dissipation effect is almost zero, so it is difficult to meet the actual use requirements. In addition, dust is easy to accumulate after long-term use, further affecting the heat dissipation. At the same time, the fixed installation is relatively cumbersome. In the existing technical solution, there is a motor drive device, including a heat dissipation side plate, the outer side of the heat dissipation side plate, etc. A card slot is provided at a distance, a card block is connected to the inner wall of the card slot by a buckle, a heat conducting plate is fixedly connected to the outer side of the card block, a heat conducting sheet is equidistantly provided on the outer side of the heat conducting plate, a cooling fan is provided at the front end of the heat conducting sheet, a fixing seat is provided at the upper and lower ends of the heat conducting sheet, a winding iron core is provided inside the fixing seat, which solves the problem of low heat dissipation efficiency of the current motor drive device, but this solution also has certain drawbacks. Although the heat sink is directly plugged into the heat conducting plate for easy disassembly, the heat conducting plate is still fixed to the protective shell by bolts, and the disassembly and assembly is still cumbersome.

[0027] A motor driver is an actuator that converts electrical pulses into angular displacement. When a stepper driver receives a pulse signal, due to the large number of internal circuits, there are many integrated circuit components, so a lot of heat will be generated during operation. If the heat dissipation effect is not good, it is easy to cause damage to the internal components and affect its normal operation.

[0028] In the related art, there is a prior art solution in which a motor drive device is provided, including a heat dissipation side plate, the outer side of the heat dissipation side plate is equidistantly provided with card slots, the inner wall of the card slot is buckled and connected with a card block, and the heat dissipation problem is solved by a heat conducting plate and a heat sink. However, this solution also has certain disadvantages. Although the heat sink is directly plugged into the heat conducting plate for easy disassembly, the heat conducting plate is still fixed to the protective shell by bolts, and the disassembly and assembly is still cumbersome and has certain limitations.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a motor drive device. When in use, the motor driver only needs to be placed in the protective shell 11, and then the upper heat conduction plate 13 is placed on the top and fixed by the installation component 2, and then the upper heat sink 14 is placed on the heat conduction plate 13 and fixed by the installation component 2 in the same way. Then, when disassembling, replacing and cleaning, it can be removed by adjusting the component 3, which is convenient and quick.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-2 FIG. 1 , an embodiment of the present application provides a motor drive device, wherein a main body component 1 comprises: a protective shell 11 in which an integrated circuit board 12 is arranged; a heat conducting plate 13 is arranged above the protective shell 11; a heat sink 14 is arranged above the heat conducting plate 13; a heat dissipation fan 15 is arranged at one end of the heat sink 14; a mounting component 2 is arranged on the protective shell 11, and the mounting component 2 comprises: a clamping cavity 21 opened on the side of the protective shell 11; a spring 24, one end of the spring 24 is fixed in the clamping cavity 21; a clamping block 22 is arranged in the clamping cavity 21, and the clamping block 22 is fixed to the other end of the spring 24; a clamping member 25 is arranged on the heat conducting plate 13.

[0032] When in use, just place the motor drive into the protective shell 11, and then place the heat conducting plate 13 on top.

The clamping cavity 21 is provided with a spring 24 and a clamping block 22. The clamping piece 25 is clamped by the clamping block 22 to achieve fixation, which is convenient and quick. The same is true for the heat sink 14, which can be plugged into the installation component 2 on the heat conducting plate 13. At the same time, if it needs to be disassembled, it only needs to be disassembled through the adjustment component 3, which greatly improves its convenience.

[0033] Specifically, the integrated circuit board 12 is arranged on the motor driver, and the heat conducting plate 13 is listed here only to express that when placed, it is placed on the integrated circuit board 12 to dissipate heat.

[0034] In some embodiments, the mounting assembly 2 is provided in multiple groups, so that it can be fixedly installed more stably.

[0035] In some embodiments, the installation components 2 located on the same side of the protective shell 11 are arranged in a mirror image.

First, the handle 34 is rotated to drive the wire rope 32 to wind, and then the clamping block 22 on the two-layer installation component 2 is pulled by the wire rope 32 to move, so that the clamping part 25 is separated from the clamping cavity 21, and finally disassembly is achieved.

[0037] In some embodiments, the adjustment component 3 also includes: a U-shaped rod 31 is arranged on the clamping block 22 at the same end of both sides of the protective shell 11, and the U-shaped rod 31 connects the installation components 2 on both sides, so that all the installation components 2 can be adjusted and disassembled by controlling on one side.

[0038] In some embodiments, each of the clamping members 25 is provided with a passage slot 26 , which allows the U-shaped rod 31 to move and prevents movement interference.

[0040] In some embodiments, the heat conducting plate 13 is also provided with the same number of mounting components 2 and adjustment components 3 as those on the protective shell 11.
