Description

Motor brake module

This case relates to a motor brake module, and more particularly to a motor brake module that is not easily vibrated when the motor is braked.

Generally speaking, the motor brake module is mounted on the motor, and is used for decelerating, stopping or more accurately positioning the motor. The conventional motor brake module is shown in Figs. 1A, 1B, 2A, and 2B. Among them, Fig. 1A is a schematic diagram of the structure of the conventional motor brake module, and Fig. 1B is the conventional motor brake module shown in Fig. 1A. A schematic diagram of the structure from another perspective. FIG. 2A is a schematic diagram of the conventional motor brake module shown in FIG. 1A when it is not braked, and FIG. 2B is a conventional motor brake module shown in FIG. 2A. A schematic view of the structure from another perspective. The conventional motor brake module 1 is used in the motor 11 to brake the motor 11 and has ratchet teeth 12, a blocking member 13, and an armature base 14, of which the ratchet teeth 12 It is sleeved on the rotating shaft 111 of the motor 11 and is located between the blocking member 13 and the armature base 14 so that the ratchet 12 is rotated by being driven by the rotating shaft 111 of the motor 11, and the ratchet 12 has a plurality of teeth 121 and a plurality of teeth 121. Each tooth 121 also rotates around the shaft 111 of the motor 11 in synchronization with the rotation of the ratchet 12. In addition, the armature base 14 is used to drive the blocking member 13 in the direction of the armature base 14 or away from the armature base 14. Move in the direction.

When the motor 11 does not need to brake, as shown in Figures 1A and 1B, not only the rotating shaft 111 of the motor 11 drives the ratchet 12 to rotate, but also the armature base 14 drives the blocking member 13 to move away from the armature base 14 so that the blocking The piece 13 is not in contact with the tooth portion 121 of the ratchet tooth 12. When the conventional motor brake module 1 wants to brake the motor 11, as shown in FIGS. 2A and 2B, the armature base 14 drives the blocking member 13 to move in the direction of the armature base 14, so that the blocking member 13 moves to the ratchet. The position of the same height of the teeth 12 abuts against one of the tooth portions 121, thereby blocking the rotation of the ratchet teeth 12 and stopping the rotation of the rotating shaft 111 of the motor 11 to achieve the purpose of braking the motor 11. However, because the plurality of teeth 121 have a large angular distance from each other, when the blocking member 13 and one of the teeth 121 abut against each other, the conventional motor brake module 1 is apt to be caused by the plurality of teeth 121. The existence of large angular intervals results in a large backlash, which makes the conventional motor brake module 1 lack of easy vibration when performing the braking operation.

Therefore, how to develop a motor brake module that can improve the lack of the conventional technology is a problem that needs to be solved by those skilled in the related art.

The purpose of this case is to provide a motor brake module, which solves the lack of the conventional motor brake module which has a large backlash, which causes easy vibration during the braking operation.

The brake component is located between the housing and the driving part, and includes a shaft hole, a plurality of teeth and a plurality of perforations. The shaft hole is provided for the shaft portion to pass through, so that the brake component rotates synchronously when the shaft portion rotates. The armature base assembly is arranged on the housing and is connected with the blocking assembly to drive the blocking assembly to move between the armature base assembly and the braking assembly, so that when the blocking assembly moves toward the braking assembly, the blocking assembly A part of the structure abuts against one of the plurality of teeth, and the blocking component has a part of the structure through one of the plurality of perforations to brake the motor.

Please refer to FIGS. 3-6, wherein FIG. 3 is a schematic structural diagram of a motor brake module of the first preferred embodiment of the present invention, and FIG. 4 is an exploded view of the structure of the motor brake module shown in FIG. FIG. 5 is a schematic diagram of the side structure of the motor brake module shown in FIG. 3 when it is not braked, and FIG. 6 is a schematic diagram of the side structure of the motor brake module shown in FIG. 3 when it is not braked. As shown in Figs. 3-6, the motor brake module 2 of this embodiment may be, but is not limited to, applied to the automation industry, for example, applied to a robot module, and used to control a motor 41, such as a motor in a robot module. To perform a braking operation, wherein the motor 41 includes a housing 410, a rotating shaft portion 411, and a driving portion 412. The housing 410 covers the motor brake module 2, at least a portion of the driving portion 412, and at least a portion of the shaft portion 411. The rotating shaft portion 411 is provided on the driving portion 412. When the motor 41 receives electric power and operates, the rotating shaft portion 411 is driven by the driving portion 412 to rotate correspondingly. Of course, the motor brake module 2 can also be applied to devices with motors in other fields, and is not limited thereto.

The motor brake module 2 includes a brake component, a blocking component, and an armature seat component. In this embodiment, the brake assembly is located between the housing 410 and the driving portion 412 and includes a brake pad 22. The brake pad 22 is located between the housing 410 and the driving portion 412 of the motor 41 and includes a main body 221 and a plurality of Of the teeth 222. The plurality of tooth portions 222 are respectively protruded from the outer edge of the main body 221 and surround the outer edge of the main body 221. Each tooth portion 222 can abut against the first blocking member 24. The main body 221 includes a shaft hole 223 and a plurality of perforations 224. The shaft hole 223 is provided at the center of the body 221 for the shaft portion 411 of the motor 41 to pass through, so that the brake plate 22 rotates synchronously when the shaft portion 411 rotates. A plurality of perforations 224 pass through the main body 221 and are arranged around the rotation shaft hole 223 and are respectively interposed between the outer edge of the main body 221 and the rotation shaft hole 223. Each of the perforations 224 can be penetrated by the second blocking member 25.

In this embodiment, the blocking component is connected to the armature base component and includes a first blocking member 24 and a second blocking member 25. The first blocking member 24 is connected to the first armature base 231 and is located between the first armature base 231 and the brake pad 22. In addition, the position of the first blocking member 24 is connected to the main body 221 of the brake pad 22. The outer edge corresponds. The second blocking member 25 is connected to the second armature base 232 and is located between the second armature base 232 and the brake pad 22. In addition, the second blocking member 25 is disposed with a plurality of perforations 224 in the main body. The position on 221 corresponds.

In this embodiment, the armature base assembly is used to drive the blocking assembly to move between the armature base assembly and the brake assembly, and is disposed on the housing 410 and includes a first armature base 231 and a second armature base 232. . The first armature base 231 is disposed on the housing 410 to drive the first blocking member 24 to move between the first armature base 231 and the brake pad 22. When the first armature base 231 drives the first blocking member 24 When moving toward the brake pad 22, the first blocking member 24 will abut against one of the plurality of teeth 222 during the rotation of the brake pad 22 to brake the motor 41, otherwise, when the first When an armature base 231 drives the first blocking member 24 to move in the direction of the first armature base 231, the first blocking member 24 does not abut against any of the tooth portions 222 of the plurality of tooth portions 222, and then stops the motor 41 Brake action. The second armature base 232 is disposed on the housing 410 and is disposed adjacent to the first armature base 231 to drive the second blocking member 25 to move between the second armature base 232 and the brake pad 22, when When the second armature base 232 drives the second blocking member 25 to move toward the brake pad 22, the second blocking member 25 will penetrate one of the plurality of perforations 224 during the rotation of the brake pad 22 to The motor 41 brakes. On the contrary, when the second armature base 232 drives the second blocking member 25 to move in the direction of the second armature base 232, the second blocking member 25 does not pass through any of the plurality of perforations 224. Then, the braking operation of the motor 41 is stopped. As can be seen from the above, in this embodiment, when the armature seat assembly drives the blocking assembly to move in the direction of the braking assembly, the blocking assembly has a partial structure that abuts against one of the plurality of teeth 222, that is, when When the first armature base 231 drives the first blocking member 24 to move toward the brake pad 22, the first blocking member 24 abuts against one of the plurality of teeth 222. In addition, when the armature base assembly drives the blocking assembly to move in the direction of the brake assembly, the blocking assembly is partially structured with one of the plurality of perforations 224, that is, when the second armature base 232 drives the second blocking member When the 25 is moved in the direction of the brake pad 22, the second blocking member 25 passes through one of the plurality of perforations 224.

In some embodiments, the first blocking member 24 and the second blocking member 25 may be disposed in parallel and parallel to the rotation shaft portion 411 respectively. In some embodiments, the motor brake module 3 may further include an encoder, but the arrangement of the encoder does not affect the operation of the present invention, so it is not shown in the drawings of this case.

The operation of the motor brake module 2 will be briefly described below. When the motor brake module 2 does not need to brake the motor 41, as shown in FIG. 5, not only the rotation shaft portion 411 of the motor 41 will rotate to drive the brake pad 22 to rotate, but also the first blocking member 24 is held by the first armature seat. 231 is magnetically moved away from the brake pad 22, that is, moved toward the first armature base 231, while the second blocking member 25 is magnetically moved by the second armature mount 232 toward the direction away from the brake pad 22, That is, it moves in the direction of the second armature base 232, so the first blocking member 24 does not abut against any of the teeth 222, and the second blocking member 25 does not pass through any perforations 224.

Conversely, when the motor brake module 2 intends to brake the motor 41, as shown in FIG. 6, the first blocking member 24 is driven by the first armature base 231 to move toward the brake pad 22, so that the first blocking The piece 24 abuts against one of the plurality of teeth 222 of the brake pad 22. At the same time, the second blocking member 25 is driven by the second armature base 232 toward the brake pad 22, so that the second blocking member 25 passes through one of the plurality of perforations 224 of the brake pad 22. In this way, the first stopper 24 abuts one of the plurality of teeth 222 of the brake pad 22, and the second stopper 25 passes through one of the plurality of perforations 224 of the brake pad 22. When one of the holes 224 is perforated, the brake pad 22 can be stopped from rotating, and the rotation shaft portion 411 of the motor 41 can be stopped to achieve the effect of braking the motor 41.

It can be known from the above that the motor brake module 2 of this case uses the first blocking member 24 to abut against the tooth portion 222 of the brake pad 22, and uses the second blocking member 25 to penetrate the perforation 224 of the brake pad 22, thereby achieving The effect of braking the motor 41, therefore, compared with the conventional tooth brake 121 of the motor brake module 1, there is a larger backlash. The motor brake module 2 of the present case actually uses a second stopper 25 through the perforation 224 provided on the brake pad 22 to reduce the possible backlash between the plurality of teeth 222 of the brake pad 22, so the motor brake module 2 in this case has the advantage of a small backlash, which can make the motor brake The module 2 does not easily vibrate when braking the motor 41.

Corresponding perforations 224 are arranged on the main body 221 in the direction, so that each tooth 222 corresponds to two perforations 224 adjacent to each other. Therefore, the number of perforations 224 is actually equal to twice the number of the perforations 222. In addition, when the brake pad 22 rotates clockwise, as shown in FIG. 7, the first stopper 24 will abut against the first side 225 of one of the plurality of teeth 222, and the second stop The piece 25 is provided with a perforation 224 adjacent to the first side 225 of the tooth portion 222 that abuts against the first blocking member 24. Conversely, when the brake pad 22 rotates counterclockwise, the first blocking member 24 will be in contact with a plurality of teeth The second side 226 of one of the teeth 222 of one of the portions 222 abuts against each other, and the second blocking member 25 passes through a perforation 224 adjacent to the second side 226 of the tooth portion 222 abutting against the first blocking member 24. Among them, in FIG. 7, the first blocking member 24 and the second blocking member 25 are shown by dotted lines, respectively.

As shown, the brake pad 22 of this embodiment is similar to the brake pad 22 shown in FIG. 7, but the size of each hole 224 of the brake pad 22 of this embodiment is actually larger than the size of the second stopper 25. Moreover, the shape of each perforation 224 may be, but not limited to, an oval shape. In addition, each perforation 224 corresponds to a single perforation 224 adjacent to each other. Therefore, in this embodiment, the number of perforations 224 is actually equal to the teeth The number of 222. In addition, when the brake pad 22 rotates clockwise, as shown in FIG. 8, the first stopper 24 will abut against the first side 225 of one of the plurality of teeth 222, and the second stop The member 25 is a perforation 224 adjacent to the tooth portion 222 which abuts against the first blocking member 24 and abuts against the inner wall surface of the perforation 224 which is worn. The position of the inner wall surface corresponds to the first side 225 of the tooth portion 222 that abuts against the first blocking member 24. Conversely, when the brake pad 22 rotates counterclockwise, the first blocking member 24 will be in contact with the plurality of tooth portions 222. The second side 226 of one of the tooth portions 222 abuts against the second side 226, and the second blocking member 25 is provided with a perforation 224 adjacent to the tooth portion 222 abutting against the first blocking member 24, and is in contact with the perforated 224 provided.
