Description

Technical Field

[0001] This utility model relates to the field of stepper motor manufacturing, and in particular to an automatic assembly device for stepper motor cover plates. Background Technology

[0002] A stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. When manufacturing a stepper motor, a cover needs to be installed.

[0003] Currently, installation is usually done manually by hand, which is slow and dangerous because if the worker doesn't hold it properly, the entire stepper motor might start spinning.

[0004] Therefore, we need to provide an automatic assembly device for stepper motor cover plates. Utility Model Content

[0005] In order to overcome the shortcomings of existing manual hand-held installation, which is dangerous if the operator does not hold the stepper motor properly and the entire stepper motor may start to rotate, the technical problem of this utility model is to provide an automatic assembly device for stepper motor cover plates.

[0006] The technical implementation scheme of this utility model is as follows: an automatic assembly device for a stepper motor cover plate, comprising a base, a cylinder, guide rods, a sliding plate and an electric screwdriver. The cylinder is mounted on the base, and multiple guide rods are circumferentially mounted on the base. The output shaft of the cylinder is connected to the sliding plate, which is slidably connected to the guide rods. Multiple electric screwdrivers are mounted on the sliding plate, and the electric screwdrivers correspond to the locking screws of the stepper motor.

[0007] In a preferred embodiment of this utility model, it further includes a limiting block, a dual-axis motor, a screw, a limiting rod, and clamping plates. Limiting blocks are installed on both sides of the base, and a dual-axis motor is installed in the middle of the base. A screw is connected to the output shaft of the dual-axis motor. A limiting rod is fixedly installed between the two limiting blocks. The screw and the limiting rod are adjacent to each other and are rotatably connected to the limiting blocks. Two clamping plates are slidably provided between the screw and the limiting rod, and the two clamping plates are separated by the base.

[0008] In a preferred embodiment of this utility model, the two clamping plates are angled on the side that is close to each other, which makes it easier to fix the stepper motor.

[0009] In a preferred embodiment of the present invention, the device further includes a fixing plate, an electric telescopic rod, and a push plate. The fixing plate is installed on one side of the base, and multiple electric telescopic rods are provided on the fixing plate. The push plate is connected between the output shafts of the electric telescopic rods.

[0010] In a preferred embodiment of the present invention, a baffle is also included, and multiple baffles are installed circumferentially on the top of the base.

[0011] In a preferred embodiment of this utility model, a pad is installed on the side of the push plate away from the electric telescopic rod.

[0012] In a preferred embodiment of this invention, a stop is installed at the top of the guide rod.

[0013] In a preferred embodiment of this utility model, there are four electric screwdrivers, each corresponding to one of the four screws of the stepper motor.

[0014] The beneficial effects of this utility model are as follows: 1. By opening the cylinder, the cylinder will drive the sliding plate and the electric screwdriver to move downward. When the electric screwdriver comes into contact with the fixing screw of the stepper motor, the electric screwdriver will start, so that the fixing screw is tightened, thus achieving the effect of automatic assembly of the stepper motor.

[0015] 2. By turning on the dual-axis motor, the output shaft of the dual-axis motor rotates, which drives the screw to rotate. The rotation of the screw causes the two clamping plates to move in the same direction, so that the clamping plates can clamp the stepper motor, achieving a stable effect during automatic assembly of the stepper motor.

[0022] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names.

[0023] Example 1

[0024] An automatic assembly device for a stepper motor cover plate, such as Figures 1-5 As shown, the system includes a base 1, a cylinder 2, guide rods 3, a sliding plate 4, an electric screwdriver 5, a limiting block 6, a dual-axis motor 7, a screw 8, a limiting rod 9, a clamping plate 10, a fixing plate 11, an electric telescopic rod 12, a push plate 13, and a baffle 14. The cylinder 2 is mounted on the base 1. Multiple guide rods 3 are circumferentially mounted on the base 1 (three in total). The sliding plate 4 is connected to the output shaft of the cylinder 2, and the sliding plate 4 is slidably connected to the guide rods 3. A stop block is mounted on the top of each guide rod 3, limiting the upward position of the sliding plate 4. Multiple electric screwdrivers 5 are mounted on the sliding plate 4, corresponding to the locking screws of the stepper motor (four in total). Limiting blocks 6 are mounted on both sides of the base 1, and the dual-axis motor 7 is mounted in the middle of the base 1. The output shaft of the dual-axis motor 7 is connected to the screw 8. The limiting rod 9 is fixedly installed between the two limiting blocks 6. The screw 8 and the limiting rod 9 are adjacent to each other. The screw 8 and the limiting block 6 are rotatably connected. Two clamping plates 10 are slidably provided between the screw 8 and the limiting rod 9. The two clamping plates 10 are separated by the base 1. The side of the two clamping plates 10 that is close to each other is at an angle. The angle allows the stepper motor to move more accurately to the middle of the base 1, which is convenient for fixing the stepper motor. A fixing plate 11 is installed on one side of the base 1. The fixing plate 11 is provided with a plurality of electric telescopic rods 12. The output shafts of the electric telescopic rods 12 are connected to the push plate 13. A pad is installed on the side of the push plate 13 away from the electric telescopic rods 12. A plurality of baffles 14 are installed circumferentially on the top of the base 1. There are four baffles 14, two on the front and two on the back.

[0025] When this device is needed, first place the stepper motor on the base 1, then activate the electric telescopic rod 12. The electric telescopic rod 12 will push the stepper motor to the center of the base 1. During this push, the baffle 14 will limit the stepper motor to prevent it from moving erratically and causing positional deviation. Then activate the dual-axis motor 7. The rotation of the output shaft of the dual-axis motor 7 will drive the screw 8 to rotate. The rotation of the screw 8 will cause the two clamping plates 10 to move in a similar direction, allowing the clamping plates 10 to clamp the stepper motor. The angled side of the clamping plates 10 can also clamp any misaligned stepper motor. The position of the stepper motor will be offset by the two clamping plates 10. The angled surface continuously presses the stepper motor towards the center, allowing for more accurate fixation. Then, the cylinder 2 is activated, causing the sliding plate 4 and the electric screwdriver 5 to move downwards together. When the electric screwdriver 5 contacts the fixing screw of the stepper motor, it activates, tightening the fixing screw on the stepper motor. After the stepper motor is assembled, the dual-axis motor 7 reverses its drive, causing the screw 8 to reverse. Then, the two clamping plates 10 move in opposite directions, removing the stepper motor. The electric telescopic rod 12 is then activated again to push the stepper motor to the appropriate position. Repeating the above operations allows for continuous assembly of the stepper motor.

[0026] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
