Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a grinding device for processing stepper motor driver circuit boards. Background Technology

[0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. A stepper motor and its driver constitute a stepper motor drive system. The performance of a stepper motor drive system depends not only on the performance of the stepper motor itself but also on the quality of the stepper motor driver. Research on stepper motor drivers has been conducted almost simultaneously with research on stepper motors.

[0003] When processing the circuit board of the stepper motor driver, it is usually done manually to position and adjust the sides one by one for grinding. The whole process requires manual adjustment of the position, which is cumbersome and has low overall efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a grinding device for processing stepper motor driver circuit boards, thereby solving the problems mentioned in the background art.

[0005] A grinding device for processing a stepper motor driver circuit board includes a worktable and a grinding mechanism mounted on the worktable. The grinding mechanism includes a first motor, a bidirectional lead screw, a moving arm, a moving table, a second motor, a base, a support platform, a swing arm, a placement table, a gear ring, a gear, a third motor, a reduction motor, a cylinder, and a pressure application part. Two first motors are mounted opposite each other on the worktable. The bidirectional lead screw is mounted at the output end of the first motor. Two moving arms are mounted opposite each other at the ends of the bidirectional lead screw. The moving table is slidably mounted on the moving arm. The second motor is mounted at the top of the moving table. The base is rotatably mounted at the bottom end of the moving table. The swing arm is mounted at the output end of the reduction motor and passes through the base. The support platform is mounted in the middle of the worktable. The placement table is rotatably mounted on the support platform. The gear ring is fixed to the outer wall of the placement table. The gear is mounted at the output end of the third motor and meshes with the gear ring. The cylinder is mounted on the worktable via a bracket. The pressure application part is rotatably mounted at the output end of the cylinder.

[0006] By adopting the above technical solution, it is convenient to automatically grind the periphery of the circuit board, saving the time of manual adjustment.

[0007] The two motors on the two moving platforms are arranged opposite each other and symmetrical about the vertical center point of the support platform.

[0008] By adopting the above technical solution, the two sides of the circuit board are simultaneously ground.

[0009] The diameter of the through hole on the base is adapted to the outer wall diameter of the swing arm, and the length of the swing arm is greater than the length of its diagonal when the maximum distance between the two sets of moving arms is greater than the maximum distance between them.

[0010] By adopting the above technical solution, circuit boards of different sizes can be placed and polished.

[0011] The pressure-applying part is positioned directly above the placement platform, and is rotatably mounted at the cylinder output end via a rotating shaft.

[0012] By adopting the above technical solution, the position of the side of the circuit board can be easily adjusted.

[0013] The cutting blade of the second motor is positioned at the top surface of the placement platform.

[0014] By adopting the above technical solution, the circuit board is placed on the placement table for grinding.

[0015] The beneficial effects of the edge grinding device for processing stepper motor driver circuit boards of this utility model are:

[0016] Drive motor one drives two moving arms to move relative to each other via a two-way lead screw. The base moves along the swing arm, and the moving table synchronously drives motor two, so that the grinding disc of motor two is in contact with the side of the circuit board. Motor two is started, and the reduction motor is started to drive the base to move along the moving arm via the swing arm. Then, the grinding disc of motor two grinds the side of the circuit board. Because the pressure part is rotatably connected to the output end of the cylinder through a rotating shaft, after the two sides of the circuit board are ground, drive motor one pulls the distance between the two motors two, and then drive motor three to drive the gear ring to rotate, so that the circuit board on the platform can be rotated 90 degrees synchronously. Then, the other two sides of the circuit board can be ground by the grinding mechanism. This makes it convenient to automatically grind the perimeter of the circuit board and saves the time of manual adjustment. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3 A grinding device for processing a stepper motor driver circuit board includes a worktable 1 and a grinding mechanism mounted on the worktable 1. The grinding mechanism includes a first motor 2, a double-acting lead screw 3, a moving arm 4, a moving table 5, a second motor 6, a base 7, a support table 8, a swing arm 9, a placement table 10, a gear ring 11, a gear 12, a third motor 13, a reduction motor 14, a cylinder 16, and a pressure application part 17. Two first motors 2 are mounted opposite each other on the worktable 1. The double-acting lead screw 3 is mounted at the output end of the first motor 2. Two moving arms 4 are mounted opposite each other at the ends of the double-acting lead screw 3. At the location, the moving platform 5 is slidably set on the moving arm 4, the second motor 6 is installed at the top of the moving platform 5, the base 7 is rotatably installed at the bottom of the moving platform 5, the swing arm 9 is installed at the output end of the reduction motor 14 and passes through the base 7, the support platform 8 is installed in the middle of the worktable 1, the placement platform 10 is rotatably installed on the support platform 8, the gear ring 11 is fixed to the outer wall of the placement platform 10, the gear 12 is installed at the output end of the third motor 13 and meshes with the gear ring 11 for transmission, the cylinder 16 is installed on the worktable 1 through the bracket 15, and the pressure part 17 is rotatably installed at the output end of the cylinder 16.

[0023] When in use, place the circuit board to be processed on the placement table 10, and drive the cylinder 16 to push the pressure part 17 downward to press the circuit board, so that the circuit board is confined between the placement table 10 and the pressure part 17. (It should be noted that the circuit board should be placed neatly so that the side of the circuit board is flush with the grinding disc of the motor 6, so as to facilitate subsequent grinding of the circuit board.)

[0024] At this time, the drive motor 2 can drive the two moving arms 4 to move relative to each other through the bidirectional lead screw 3. At this time, the base 7 moves along the swing arm 9, and the moving table 5 drives the motor 6 in sync, so that the grinding disc of the motor 6 is attached to the side of the circuit board. Then the motor 6 is started, and the reduction motor 14 is started to drive the base 7 to move along the moving arm 4 through the swing arm 9, and then the grinding disc of the motor 6 is used to grind the side of the circuit board.

[0025] Because the pressure unit 17 is rotatably connected to the output end of the cylinder 16 via a rotating shaft, after the two sides of the circuit board are ground, the drive motor 12 pulls the distance between the two motors 26, and then the drive motor 3 13 drives the gear ring 11 to rotate through the gear 12, so that the circuit board on the placement platform 10 can rotate 90 degrees synchronously. Then the other two sides of the circuit board can be ground by the grinding mechanism.

[0026] The motors 6 on the two moving platforms 5 are arranged opposite each other and symmetrical about the vertical center point of the support platform 8. The motors 6 are fixedly installed on the moving platforms 5 by the mounting bracket, while the base 7 is rotatably installed on the bottom of the moving platforms 5. When the reduction motor 14 drives the swing arm 9 to swing, the swing arm 9 can drive the moving platform 5 to slide along the moving arm 4 through the base 7 to adjust the position of the motors 6.

[0027] The diameter of the through hole on the base 7 is matched with the outer wall diameter of the swing arm 9, and the length of the swing arm 9 is greater than the length of its diagonal when the maximum distance between the two sets of moving arms 4 is greater. Since the size of the circuit board may be different, in order to achieve side grinding of circuit boards of various specifications as much as possible, the swing arm 9 is lengthened to drive the moving table 5 to move along the moving arm 4, so as to completely grind the side of the circuit board.

[0028] The pressure application part 17 is positioned directly above the placement platform 10, and is rotatably mounted on the output end of the cylinder 16 via a rotating shaft. When the circuit board is placed on the placement platform 10, the cylinder 16 pushes the pressure application part 17 to apply pressure to the circuit board, thereby ensuring that the circuit board is restricted and positioned. After the two sides of the circuit board are ground, the placement platform 10 can be driven to rotate. Since the pressure application part 17 and the output end of the cylinder 16 are rotatably connected, the circuit board can be adjusted to rotate when the placement platform 10 and the pressure application part 17 restrict and position the circuit board. (This device is not limited to grinding the sides of the circuit board, but also grinds the corners after adjusting the position.)

[0029] The cutting blade of motor 26 is positioned at the top surface of the placement table 10; the cutting blade of motor 26 always corresponds to the height of the placement table 10, and after the circuit board is placed on the placement table 10, the sides of the circuit board can be completely ground.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
