DETAILED DESCRIPTION

[0074] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0075] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0076] like Figure 1 , Figure 2 FIG. 1 is a schematic diagram of a structure of an electric chuck device based on PLC control provided by an embodiment of the present invention, comprising:

[0077] Install the housing 1;

[0078] A mounting bracket 2, wherein the mounting bracket 2 is disposed on the mounting housing 1 and is connected to a control system 100 for driving the mounting bracket 2 to move;

[0079] A mounting base 3, wherein the mounting base 3 is fixed on the mounting bracket 2;

[0080] End seats 4, the end seats 4 are fixed to both ends of the mounting base 3, and an actuator 200 is rotatably arranged between the two end seats 4;

[0081] A movable shell 5, wherein the movable shell 5 is slidably disposed in the end seat 4;

[0082] A first drive sleeve 6, wherein the first drive sleeve 6 is slidably connected to the actuator 200, the first drive sleeve 6 is slidably connected to the end seat 4, and the first drive sleeve 6 is rotatably connected to the movable shell 5;

[0083] A second driving sleeve 7, wherein the second driving sleeve 7 is rotatably disposed at an end of the end seat 4 away from the actuator 200;

[0084] A first driving rod 8, wherein the first driving rod 8 is slidably connected to the second driving sleeve 7, the first driving rod 8 is rotatably connected to the movable shell 5, and the first driving rod 8 is connected to one end of the first driving sleeve 6 located in the movable shell 5 through a gear pair;

[0085] A first elastic member 9, two ends of which are respectively connected to the outer wall of the movable shell 5 and the inner wall of the end seat 4;

[0086] A scraper 10, wherein the scraper 10 abuts against the surface of the actuator 200;

[0087] A driving mechanism 300, wherein the driving mechanism 300 is used to utilize the movement of the first driving rod 8 to drive the scraping member 10 to move synchronously;

[0088] The state control unit 400 is used to automatically control the rotation state of the first driving rod 8 .

[0089] In the embodiment of the present invention, when in use, the actuator 200 is inserted between each actuator 200. At this time, the control system 100 controls the mounting bracket 2 to move toward the direction close to the actuator 200, and the mounting bracket 2 drives the mounting base 3, the end seat 4, and the actuator 200 to move. First, the actuator 200 contacts the actuator 200, and the mounting base 3 is in the contact position. Then the actuator 200 squeezes the actuator 200, and the actuator 200 drives the first drive sleeve 6, the end seat 4, the gear pair and the first drive rod 8 to move. The movable shell 5 squeezes the first elastic member 9 until it cannot move. At this time, the mounting base 3 is in a predetermined clamping position; then the control system 100 stops driving the actuator 200. The mounting bracket 2 is controlled by the state control unit 400 to switch the first driving rod 8 from the initial non-rotatable state to the unidirectional rotation state. In this state, the actuator 200 can only continue to move toward the device in one direction, so that the position of the actuator 200 to be processed can be adjusted without retreating. It has a stable feeding state and improves the positioning accuracy. When the actuator 200 continues to feed, the actuator 200 is driven to rotate by friction, and the actuator 200 drives the first driving sleeve 6 to rotate. The first driving sleeve 6 drives the first driving rod 8 to rotate through the gear pair until the actuator 200 moves to the processing area. Then, on the one hand, the mounting bracket 2 is controlled to continue to move by the control system 100 to increase The holding force is increased so that the actuator 200 cannot move during processing. On the other hand, the state control unit 400 controls the first driving rod 8 to switch from the unidirectional rotation state to the free rotation state, and at this time, the mounting base 3 is in a fixed clamping position; in the process of the mounting base 3 moving from the initial position to the predetermined clamping position, the first driving rod 8 moves, and the driving mechanism 300 synchronously drives the scraping member 10 to move toward the mounting base 3 through its movement, so that the scraping member 10 is away from the actuator 200, which facilitates the rotation of the actuator 200, and the state control unit 400 controls the first driving rod 8 to switch from the unidirectional rotation state to the free rotation state; after the processing of the actuator 200 is completed, , the control system 100 controls the mounting bracket 2 to move to the contact position in the direction away from the actuator 200. At this time, the movable shell 5 is driven to reset under the elastic force of the first elastic member 9, and the movable shell 5 drives the first drive sleeve 6, the first drive rod 8, and the actuator 200 to reset. The driving mechanism 300 uses the reset of the first drive rod 8 to abut against the surface of the actuator 200, and then the residual material after processing is taken out. The residual material drives the actuator 200 to rotate in the opposite direction, so that the scraping member 10 can be used to automatically clean the stains on the surface of the actuator 200 to a clean state. After cleaning, the state control unit 400 controls the first drive rod 8 to switch from a free rotation state to a non-rotatable state.

[0090] In one case of an embodiment of the present invention, the control system 100 includes an input / output module, which includes a servo motor and can be used to drive the mounting bracket 2 to move. The input / output module is controlled by a PLC control system, and the PLC control system is connected to a LORA wireless communication module, and the LORA wireless communication module is connected to an industrial control panel; the control system 100 also includes a rotary motor, which is used to drive the mounting shell 1 to rotate.

[0091] like Figure 6 As shown, specifically, by operating on the operation interface on the industrial control screen, the operation instructions are sent to the LORA wireless communication module. The LORA communication module transmits the instructions to the PLC module, and the PLC module controls the servo motor to perform precise operations. The motor can control the movement of the mounting bracket 2 by adopting traditional transmission structures such as screw rods and screw rod groups. The mounting bracket 2 drives the mounting base 3 and other components to operate the actuator 200, which can intelligently control the clamping force, and the clamping accuracy and control method become more diversified and intelligent.

[0092] like Figure 2 As shown, as a preferred embodiment of the present invention, the driving mechanism 300 includes:

[0093] A first connecting rod 11, wherein the first connecting rod 11 is rotatably connected to the first driving rod 8;

[0094] A first gear rod 12, which is slidably disposed in the mounting base 3 and fixedly connected to the first connecting rod 11;

[0095] A pinion 13, the pinion 13 is rotatably disposed in the mounting base 3 and meshedly connected with the first gear rod 12;

[0096] A large gear 14, wherein the large gear 14 is rotatably disposed on a side of the small gear 13 away from the first gear rod 12, and the large gear 14 is meshedly connected with the small gear 13;

[0097] A second gear rod 15, the second gear rod 15 is arranged on a side of the large gear 14 away from the small gear 13, the second gear rod 15 is meshed and connected with the large gear 14, and the second gear rod 15 is fixedly connected with the scraper 10;

[0098] The guide member 16 is slidably disposed in the mounting base 3 and fixedly connected to the second gear rod 15 .

[0099] In the embodiment of the present invention, when in use, the first driving rod 8 drives the first connecting rod 11 to move, the first connecting rod 11 drives the first gear rod 12 to move, the first gear rod 12 drives the pinion 13 to rotate, the pinion 13 drives the large gear 14 to rotate in the opposite direction, the large gear 14 drives the second gear rod 15 to move in the direction of the first gear rod 12, and the second gear rod 15 drives the scraper 10 to move. Due to the transmission ratio of the pinion 13 and the large gear 14, the moving distance of the large gear 14 is greater than the moving distance of the first gear rod 12, that is, the moving distance of the first driving rod 8, so that the distance between the actuator 200 and the scraper 10 is greater than the moving distance of the first driving rod 8, and the scraper 10 switches from the state of bending and abutting the actuator 200 to the state of being separated from the actuator 200.

[0100] It should be noted that in the initial state, the scraper 10 is bent and abuts against the actuator 200, that is, the actuator 200 is stationary without external interference, satisfying the situation that the state control unit 400 controls the first drive rod 8 to be unable to rotate in the initial state.

[0101] like Figure 3 As shown, as another preferred embodiment of the present invention, the state control unit 400 includes:

[0102] A first connecting plate 17, wherein the first connecting plate 17 is fixed in the mounting base 3;

[0103] A third driving sleeve 18, wherein the third driving sleeve 18 is rotatably connected to the first connecting plate 17;

[0104] A state control installation box 19, wherein the state control installation box 19 is fixedly connected to the first connecting plate 17, and the state control installation box 19 is rotatably connected to the third driving sleeve 18;

[0105] A fourth drive sleeve 20, wherein the fourth drive sleeve 20 is rotatably connected to the state control installation box 19, and the fourth drive sleeve 20 is slidably connected to the first drive rod 8;

[0106] A sliding sleeve 21, wherein the sliding sleeve 21 is mounted on the first driving rod 8 through a first clamping assembly, and the sliding sleeve 21 is provided with a clamping groove that cooperates with the third driving sleeve 18;

[0107] A sealing slide plate 22, wherein the sealing slide plate 22 is rotatably connected to the sliding sleeve 21, and the sealing slide plate 22 slides in a sealed manner with the state control installation box 19;

[0108] The sliding sleeve 21 is connected to the inner wall of the state control installation box 19 via a one-way limiting mechanism 500;

[0109] The sliding sleeve 21 is connected to an elastic support mechanism 600 for elastically supporting the sliding sleeve 21;

[0110] The cavity of the first driving rod 8 located on the side of the sealing slide 22 away from the end seat 4 is connected to a gas pressure control mechanism 700 for automatically controlling its pressure.

[0111] In the embodiment of the present invention, in the initial state, the first driving rod 8 can rotate along the sealing slide 22 through the first clamping assembly, and its rotation is not restricted by it. When the first driving rod 8 drives the sliding sleeve 21 and the sealing slide 22 to move upward, the sliding sleeve 21 drives the one-way limiting mechanism 500 to move, and the sliding sleeve 21 cooperates with the third driving sleeve 18 through the clamping groove, thereby restricting it, so that the third driving sleeve 18 can only rotate in one direction. Since the third driving sleeve 18 is slidingly connected to the first driving rod 8, the first driving rod 8 can only rotate in one direction. The sealing slide 22 and the sliding sleeve 21 can be driven to move by the air pressure control mechanism 700, so that the sliding sleeve 21 is separated from the third driving sleeve 18, specifically, separated from the restriction of the first clamping assembly. The sliding sleeve 21 is supported by the elastic support mechanism 600, and the first driving rod 8 is switched from the one-way rotation state to the free rotation state. After resetting, the first driving rod 8 is re-matched with the sliding sleeve 21 through the first clamping assembly.

[0112] In one case of an embodiment of the present invention, the first clamping assembly includes a clamping slider 23 and a second elastic member 24, the clamping slider 23 is slidably arranged in the first driving rod 8, one end of the clamping slider 23 is arc-shaped and partially nested in the sliding sleeve 21, and the sliding sleeve 21 is provided with an arc-shaped sliding groove matching therewith, and the two ends of the second elastic member 24 are respectively fixedly connected to the bottom wall of the clamping slider 23 and the inner wall of the first driving rod 8, and the clamping slider 23 is nested in the arc-shaped sliding groove through the elastic force of the second elastic member 24, so that the first driving rod 8, the clamping slider 23, and the sliding sleeve 21 are in a synchronous state in the moving direction of the first driving rod 8.

[0113] like Figure 3 As shown, as another preferred embodiment of the present invention, the one-way limiting mechanism 500 includes:

[0114] A ratchet groove 30, wherein the ratchet groove 30 is fixed on the inner wall of the state control installation box 19;

[0115] A fourth connecting plate 31, wherein the fourth connecting plate 31 is fixed to the outer wall of the sliding sleeve 21;

[0116] A pawl 32, the pawl 32 is rotatably disposed on the fourth connecting plate 31, and the pawl 32 is connected to the outer wall of the sliding sleeve 21 through a fifth elastic member;

[0117] The pawl 32 matches with the pawl slot 30 .

[0118] In the embodiment of the present invention, when in use, due to the restriction of the pawl groove 30 on the pawl 32, the pawl 32 can only be flipped toward the direction of the fifth elastic member, which has the effect of one-way limiting. When the first driving rod 8 drives the sealing slide 22 to move, the sealing slide 22 drives the fourth connecting plate 31 and the pawl 32 to move, so that they can disengage from the pawl groove 30, and the first driving rod 8 switches from a one-way rotation state to a free rotation state.

[0119] like Figure 3 As shown, as another preferred embodiment of the present invention, the elastic support mechanism 600 includes:

[0120] A second connecting plate 27, wherein the second connecting plate 27 is fixed to the bottom of the sliding sleeve 21;

[0121] A third connecting plate 28, wherein the third connecting plate 28 is fixed in the state control installation box 19;

[0122] The third elastic member 29 has two ends fixedly connected to the second connecting plate 27 and the third connecting plate 28 respectively.

[0123] In the embodiment of the present invention, when in use, the sliding sleeve 21 drives the second connecting plate 27 to move, thereby compressing the third elastic member 29, and then the elastic force of the third elastic member 29 drives the second connecting plate 27 and the sliding sleeve 21 to reset, and then re-match with the first clamping assembly to play the role of elastic support.

[0124] like Figure 4 As shown, as another preferred embodiment of the present invention, the air pressure control mechanism 700 includes:
