Description

Technical Field

[0001] This application relates to the field of servo all-in-one machine technology, and more specifically, to a servo all-in-one machine. Background Technology

[0002] A servo motor integrated unit, simply put, is a device that integrates a servo motor and a driver into one unit. It tightly combines the three main components of a servo system—the motor, encoder, and driver—into a compact and efficient unit. This integrated design not only simplifies the system structure but also improves the system's response speed and accuracy.

[0003] There are two main wiring methods for existing servo all-in-one machines: one is to connect the wiring to the internal circuit board, and then the wiring runs out of the servo all-in-one machine to connect to the outside; the other is to install a pluggable aviation socket on the back cover of the servo all-in-one machine, and then the rear end of the pluggable aviation socket extends into the servo all-in-one machine to connect to the internal circuit board, and can be directly connected to the external pluggable plug through the pluggable aviation socket. The advantage of the former is that there are not many external cables for the servo all-in-one machine, making the connection more convenient.

[0004] However, in existing servo PCs with pluggable aviation sockets, the sockets are usually exposed when the servo PC is not in use. Dust can easily get into the pins inside the socket, affecting the contact during power-on. In addition, when the pluggable aviation socket is connected to an external plug, the plug can easily detach from the socket when the connector is pulled by external force, resulting in poor contact between the plug and socket. This causes the servo PC to malfunction. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this application is to provide a servo all-in-one machine to solve the problem that when the servo all-in-one machine is not in use, the pluggable aviation socket on it is directly exposed to the outside, and the pins inside the socket are prone to dust, which affects the poor contact of power supply later.

[0006] To achieve the above objectives, this application provides the following technical solution: A servo all-in-one machine includes a motor body, a circuit board detachably mounted on the rear side of the motor body, a gap between the front side of the circuit board and the rear side of the motor body, a magnetic drum on the rear side of the motor body, an encoder chip on the front side of the circuit board, the encoder chip being positioned corresponding to the magnetic drum, a rear cover detachably connected to the rear side of the motor body, the circuit board being located inside the rear cover, a pluggable aviation socket mounted on one side of the rear cover, the pluggable aviation socket being electrically connected to the circuit board; it also includes a protective component for protecting the pluggable aviation socket, the protective component including semi-circular tubes located on both sides of the pluggable aviation socket, the semi-circular tubes being slidably arranged along the width direction of the rear cover, a semi-circular plate being fixed on the semi-circular tubes; it also includes a locking member for locking the semi-circular tubes onto the rear cover, the pluggable aviation socket being shielded and protected when the two semi-circular tubes are moved to close.

[0007] Preferably, a strip seat is fixedly connected to both sides of the pluggable aviation socket on the back cover. The strip seat is set along the width direction of the back cover. A groove is provided on the side of the strip seat away from the back cover. A groove with a thickness matching the strip seat is provided on the side of the semi-circular tube near the back cover. A slider is fixed in the middle of the groove and is slidably connected in the groove.

[0008] Preferably, the locking component includes a threaded post and a threaded locking ring. The top of the strip seat is provided with a strip groove that communicates with the slide groove. The middle part of the threaded post is slidably disposed in the strip groove. One end of the slider extends a length toward the outer wall of the semi-circular tube. The bottom end of the threaded post is fixedly connected to the slider. The threaded locking ring is threadedly connected to the upper part of the threaded post.

[0009] Preferably, the semi-circular plate includes a plate and a cover, the plate having a receiving groove on the side near the cover, and the cover being fixedly connected to the opening of the receiving groove of the plate.

[0010] Preferably, the middle part of the planar side of the plate and the plate cover is provided with a first arc-shaped groove and a second arc-shaped groove, respectively. The first arc-shaped groove is provided with an insertion hole that communicates with the receiving groove. A sliding block is slidably provided in the insertion hole and can slide into the receiving groove.

[0011] Preferably, a rear seat is fixedly provided on the side of the inner wall of the receiving groove away from the sliding block, a horizontally arranged guide block is fixedly connected to the inner wall of the receiving groove, the sliding block is provided with a guide groove that is adapted to slide with the guide block, and a compression spring is also included, with the two ends of the compression spring being connected and fixed to the rear seat and the sliding block respectively.

[0012] Preferably, the top and bottom of the sliding block are provided with limiting edges. When no external force is applied to the sliding block, the compression spring pushes the sliding block so that the limiting edges abut against the inner wall of the guide groove.

[0013] Preferably, multiple heat dissipation fins are fixedly connected to the rear side of the back cover.

[0014] Compared with the prior art, the beneficial effects of this application are: This servo all-in-one machine features a protective component that shields the pluggable aviation socket when it is not in use, preventing dust from entering the internal pins of the socket due to direct exposure.

[0015] When the pluggable aviation socket needs to be connected to an external plug, the two semi-circular tubes on both sides can hold the plug's wires. The locking mechanism locks the two semi-circular tubes, thus holding the plug's wires in place. This prevents the plug from being pulled away by external force, which could cause poor contact between the plug and socket, resulting in the servo all-in-one machine malfunctioning.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a technical solution: A servo all-in-one machine, please refer to Figures 1-14 The system includes a motor body 10, a circuit board 30 detachably mounted on the rear side of the motor body 10, a gap between the front side of the circuit board 30 and the rear side of the motor body 10, a magnetic drum 100 on the rear side of the motor body 10, and an encoder chip 302 on the front side of the circuit board 30. The encoder chip 302 is positioned corresponding to the magnetic drum 100. When the magnetic drum 100 rotates, the encoder chip 302 senses the rotation of the magnetic drum 100 and outputs an electrical signal indicating the position of the motor rotor to the main chip. The main chip and the encoder chip are connected through circuit board wiring. The main chip controls the motor body according to the motor rotor position signal transmitted from the encoder chip.

[0033] In this application, the circuit board 30 is a servo driver + encoder circuit board; the circuit board with driver chip and encoder chip 302 is the prior art, which centrally sets the driver and encoder on the same circuit board.

[0034] Specifically, the circuit board 30 has two round holes 300. On the side of the circuit board 30 near the motor body 10, corresponding to the positions of the two round holes 300, there are fixed pins 301. The pins 301 have a channel hole with the same diameter as the round hole 300, and the channel hole is positioned opposite to the round hole 300. The rear side of the motor body 10 has a slot 101 corresponding to the position of the pin 301. The slot 101 is adapted to the size of the pin 301. The slot 101 also has a threaded groove 102.

[0035] When installing the circuit board 30, the two pins 301 on the circuit board 30 are aligned with the two slots 101 on the motor body 10, and then the pins 301 are inserted into the slots 101. The position of the circuit board 30 can be positioned first. Since the positions of the pins 301 and the slots 101 are designed, when the pins 301 are inserted into the slots 101, the circuit board 30 is located at the center of the rear side of the motor body 10. Then, the circuit board 30 is locked by the second bolt 31. The second bolt 31 passes through the round hole 300 and the pins 301 and is threaded into the threaded groove 102, thereby fixing the circuit board 30 to the rear side of the motor body 10.

[0036] A rear cover 20 is detachably connected to the rear side of the motor body 10. The circuit board 30 is located inside the rear cover 20. A sealing gasket 50 is provided at the connection between the rear side of the motor body 10 and the front side of the rear cover 20. The sealing gasket 50 can seal the connection between the motor body 10 and the rear cover 20, effectively preventing dust from entering. Of course, the sealing gasket 50 can be glued to the front side of the rear cover 20 for easy installation. The sealing gasket 50 can be made of rubber or silicone material.

[0037] Specifically, each corner of the rear cover 20 is provided with a through hole, and the sealing gasket 50 is also provided with a corresponding through hole. Each corner of the rear side of the motor body 10 is provided with a threaded slot corresponding to the position of the through hole. It also includes a first bolt 202, which passes through the through hole and is threadedly connected to the threaded slot, so that the rear cover 20 can be installed on the rear side of the motor body 10.

[0038] In this application, multiple heat dissipation fins 200 are fixedly connected to the rear side of the back cover 20. The heat dissipation fins 200 can better dissipate heat from the back cover 20 and prevent the back cover 20 from overheating.

[0039] A pluggable aviation socket 201 is installed on one side of the back cover 20. The pluggable aviation socket 201 is electrically connected to the circuit board 30 via wires. Specifically, a mounting hole is provided on one side of the back cover 20, and the pluggable aviation socket 201 is installed at the mounting hole.

[0040] This application also includes a protective component 4 for protecting the pluggable aviation socket 201. The protective component 4 includes two semi-circular tubes 40 located on both sides of the pluggable aviation socket 201. The semi-circular tubes 40 are slidably disposed along the width direction of the rear cover 20, and a semi-circular plate 41 is fixed on the semi-circular tubes 40. Specifically, strip seats 42 are fixedly connected to both sides of the pluggable aviation socket 201 on the back cover 20. The strip seats 42 are horizontally arranged along the width direction of the back cover 20. A groove 420 is provided on the side of the strip seat 42 away from the back cover 20. A groove 400 adapted to the thickness of the strip seat 42 is provided on the side of the semi-circular tube 40 near the back cover 20. A slider 401 is fixed in the middle of the groove 400. The slider 401 is slidably connected in the groove 420. At the same time, the strip seat 42 is also placed in the groove 400, so that the semi-circular tube 40 can slide along the length direction of the strip seat 42 to adjust its position.

[0041] It also includes a locking device for locking the semi-circular tube 40 onto the rear cover 20. After the two semi-circular tubes 40 are moved together, they can shield and protect the pluggable aviation socket 201. When the servo all-in-one machine is not in use, it can protect the pluggable aviation socket 201 and prevent the pluggable aviation socket 201 from being directly exposed to the outside, which would cause dust to enter the pins inside the socket.

[0042] Specifically, the locking components include a threaded post 402 and a threaded locking ring 43. The top of the strip seat 42 is provided with a strip groove 421 that communicates with the slide groove 420. The middle part of the threaded post 402 is slidably disposed in the strip groove 421. One end of the slider 401 extends a length toward the outer wall of the semi-circular tube 40. The bottom end of the threaded post 402 is fixedly connected to the slider 401. Specifically, the bottom end of the threaded post 402 is fixedly connected to the extended length of the slider 401. The threaded locking ring 43 is threadedly connected to the upper part of the threaded post 402, so that the threaded locking ring 43 abuts against the top of the strip seat 42, thereby fixing the position of the semi-circular tube 40.

[0043] When the two semi-circular tubes 40 are brought close together, they can protect the pluggable aviation socket 201. Of course, when the two semi-circular tubes 40 are brought close together, the two semi-circular plates 41 will also be brought close together. When the pluggable aviation socket 201 needs to be used with an external plug, the two semi-circular tubes 40 can be separated from each other to facilitate the plugging of the pluggable aviation socket 201.

[0044] When existing pluggable aviation sockets are connected to external plugs, the plug can easily detach from the socket when the connector cable is pulled by external force, resulting in poor contact between the plug and socket. This causes the servo all-in-one machine to malfunction. To solve this technical problem, the following technical solution is designed: The semi-circular plate 41 includes a plate 410 and a cover 411. The plate 410 has a receiving groove 4101 on the side near the cover 411, and the cover 411 is fixedly connected to the opening of the receiving groove 4101 of the plate 410.

[0045] The middle part of the planar side of the plate 410 and the cover 411 (the side where the two plates 410 are close to each other, or the side where the two covers 411 are close to each other) is respectively provided with a first arc-shaped groove 4100 and a second arc-shaped groove 4110. The first arc-shaped groove 4100 is provided with an insertion hole 412 that communicates with the receiving groove 4101. A sliding block 413 is slidably provided in the insertion hole 412. The sliding block 413 can slide into the receiving groove 4101.

[0046] A rear seat 4102 is fixedly provided on the side of the inner wall of the receiving groove 4101 away from the sliding block 413. A horizontally arranged guide block 416 is fixedly connected to the inner wall of the receiving groove 4101. The sliding block 413 is provided with a guide groove 4130 that is slidably adapted to the guide block 416. It also includes a horizontally arranged compression spring 415. The two ends of the compression spring 415 are respectively connected and fixed to the rear seat 4102 and the sliding block 413.

[0047] Of course, guide posts can be installed on the side of the rear seat 4102 and the sliding block 413 that are close to each other. The two ends of the compression spring 415 can be respectively sleeved on the two guide posts and then connected to the rear seat 4102 and the sliding block 413. Of course, when the sliding block 413 is completely slid into the receiving groove 4101, the two guide posts will not contact or interfere.

[0048] The top and bottom of the sliding block 413 are provided with limiting edges 414. When there is no external force acting on the sliding block 413, the compression spring 415 pushes the sliding block 413 so that the limiting edges 414 abut against the inner wall of the guide groove 4130. At this time, part of the sliding block 413 will protrude from the plate 410. When the two semi-circular tubes 40 are moved closer to each other, the two sliding blocks 413 will first abut against each other. Then, as the two semi-circular tubes 40 continue to move closer, the sliding block 413 will move into the receiving groove 4101 until the two semi-circular tubes 40 abut against each other.

[0049] Of course, a rubber sealing gasket can be glued to one side of the two semi-circular tubes 40 abutting together, which can seal the joint when the two semi-circular tubes 40 abutting together.

[0050] When the pluggable aviation socket needs to be connected to an external plug, first move the two semi-circular tubes 40 apart, then plug the external plug into the pluggable aviation socket. Then move the two semi-circular tubes 40 closer together, so that the wire behind the plug is aligned with the sliding block 413. Continue to move the two semi-circular tubes 40 closer together, until the wire behind the plug is placed in the first arc groove 4100 and the second arc groove 4110. The wire connected to the plug can be clamped by the two semi-circular tubes 40 on both sides. The two semi-circular tubes 40 are locked by the locking device, which clamps the wire connected to the plug. This prevents the plug from being pulled away from the pluggable aviation socket by external force, which would cause poor contact between the plug and the socket and cause the servo all-in-one machine to malfunction.

[0051] Of course, the length of the semi-circular tube 40 is greater than the overall length of the plug and the pluggable aviation socket after they are connected.
