[0003] At present, the brush is usually replaced manually, and such manual operation needs to disassemble the pressing plate and screws and other accessories for fixing the brush, and therefore has the problems of long replacing time and inconvenient operation. In addition, the current brush needs to use special tools to install and disassemble the brush, and multiple actions are needed from installation to disassembly, and therefore the installation and disassembly steps cannot be well simplified, and therefore the time cannot be reduced in the material processing process, and therefore the material processing efficiency cannot be effectively improved. SUMMARY

[0004] In order to solve the above technical problems, the present application discloses a brush replacing system, which can realize the quick replacement of the brush, save the brush disassembly and assembly time, and effectively improve the material processing efficiency.

[0005] The specific technical scheme of the present application is as follows:

[0006] A brush replacing system comprises a brush replacing assembly, and the brush replacing assembly comprises:

[0012] a clamping assembly movably arranged in the brush receiving and releasing seat and movably connected with the moving slider;

[0013] The first driving mechanism drives the moving slider to move relative to the brush receiving and releasing seat, so that the moving slider drives the clamping assembly to switch between a releasing position and a clamping position.

[0014] The action of the first driving mechanism can drive the moving slider to move relative to the brush receiving and releasing seat, so that the moving slider drives the clamping assembly to move, so that the clamping assembly meets the requirements of releasing the brush and clamping the brush, and thereby realizes the automatic operation of the brush replacing.

[0015] Preferably, the brush replacing mechanism further comprises:

[0016] a first elastic member, one end of the first elastic member being connected with the moving slider, and the other end being connected with the brush receiving and releasing seat.

[0017] The first elastic member can keep the position of the brush replacing mechanism, so that the clamping assembly is kept in the clamping station, and when the clamping assembly is in the releasing station and the brush is in the proper position, the clamping assembly can be quickly switched from the releasing station to the clamping station through the deformation recovery of the first elastic member, thereby further improving the efficiency of replacing the brush and the position stability.

[0021] Under the driving of the moving slider, the two clamping members move towards different directions to realize the switching of the clamping assembly between the releasing station and the clamping station; since the extension direction of the waist-shaped hole is inclined to the movement path of the moving slider, when the sliding member slides in the waist-shaped hole, the sliding member can realize the rotary driving of the clamping members, thereby meeting the requirement of switching the clamping assembly between the releasing station and the clamping station.

[0033] When the telescopic mechanism is switched from the retracted position to the extended position, the telescopic mechanism slides on the inner wall of the matching hole through the inclined surface of the wedge-shaped structure, thereby pulling the brush changing mechanism from the clamped position to the loosened position.

[0034] During the process that the free end of the telescopic mechanism extends into the matching hole, the telescopic mechanism is always in contact with the matching hole in the preset telescopic direction, thereby moving the brush changing mechanism relative to the brush holder, and the brush changing mechanism is switched from the clamped position to the loosened position.

[0035] Preferably, the first driving mechanism further comprises:

[0036] a rotating mechanism arranged on the base and used for covering the telescopic mechanism in the retracted position.

DETAILED DESCRIPTION

[0058] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with specific embodiments.

[0059] As shown in Figures 1-2 , a brush replacement system comprises a brush replacement assembly 100, the brush replacement assembly 100 comprising a brush replacement mechanism 101 and a first driving mechanism 102; the first driving mechanism 102 is used to drive the brush replacement mechanism 101 to switch between a loosening position and a clamping position; the brush replacement mechanism 101 comprises a brush holder 1, a moving block 2 and a clamping assembly; the moving block 2 is movably arranged in the brush holder 1; the clamping assembly is movably arranged in the brush holder 1 and movably connected with the moving block 2; the first driving mechanism 102 drives the moving block 2 to move relative to the brush holder 1, so as to drive the clamping assembly to switch between a releasing position and a clamping position.

[0060] In the embodiment, the brush replacement assembly 100 is a component for picking up the brush 200 and releasing the brush 200, and specifically, the clamping assembly is used to clamp the brush 200. The brush 200 is provided with an annular groove 3 on the outer circumferential side, and the clamping assembly can clamp the brush 200 by extending into the annular groove 3. Of course, in another embodiment, the clamping assembly can directly clamp the outer circumferential side of the brush 200.

[0061] ​In the embodiment, the setting of the annular groove 3 can provide a limit for the clamping assembly, thereby improving the accuracy of clamping the brush 200, and the clamping of each brush 200 can be achieved at the same position, thereby improving the repeatability and better realizing the automation.

[0062] In the embodiment, the clamping assembly is driven by the movement slider 2, and the movement slider 2 is driven by the first driving mechanism 102. Therefore, when the first driving mechanism 102 is actuated, the release or clamping of the brush 200 can be achieved through the cooperation among the clamping assembly, the movement slider 2 and the first driving mechanism 102.

[0063] As shown in Figure 3 and Figure 4 Further, the clamping assembly comprises two clamping pieces 4 oppositely arranged in the brush receiving seat 1; the clamping pieces 4 are hinged to the brush receiving seat 1; the clamping pieces 4 are provided with a waist-shaped hole 5, the extension direction of the waist-shaped hole 5 is inclined to the movement path of the movement slider 2; and the movement slider 2 is provided with a sliding piece 6 matched with the waist-shaped hole 5.

[0064] It should be noted that the two clamping pieces 4 are the same in structure and are installed in the brush receiving seat 1 in the same way, and it should be understood that the two clamping pieces 4 are symmetrically arranged in the brush receiving seat 1, thereby better achieving the clamping of the brush 200. Specifically, when the brush replacing mechanism 101 is at the loosening position, the movement slider 2 is driven to slide relative to the brush receiving seat 1 by the action of the first driving mechanism 102, and then the two clamping pieces 4 are driven to rotate away from each other, thereby reserving the space for the brush 200 to enter the brush receiving seat 1. When the brush 200 is at the clamping position, the first driving mechanism 102 is reversely actuated, at this time, the two clamping pieces 4 are rotated towards each other, thereby clamping the brush 200 on the brush receiving seat 1.

[0065] In the embodiment, a movement guide piece is arranged between the movement slider 2 and the brush receiving seat 1.

[0066] Specifically, the movement guide piece comprises a sliding groove 7 and a limiting block 8 which are slidably matched with each other, one of the sliding groove 7 and the limiting block 8 is arranged on the movement slider 2, and the other is arranged on the brush receiving seat 1. In the embodiment, the sliding groove 7 is arranged on the movement slider 2, and the limiting block 8 is arranged on the brush receiving seat 1. The extension direction of the sliding groove 7 is consistent with the movement direction of the movement slider 2, thereby further providing the movement stability of the clamping assembly between the release station and the clamping station.

[0067] To better utilize this embodiment, a portion of the motion slider 2 extends out of the brush take-up and take-down seat 1, and this portion is provided with a mating hole 9; the free end of the first drive mechanism 102 extends into the mating hole 9 to drive the motion slider 2 to move relative to the brush take-up and take-down seat 1.

[0068] Furthermore, such as Figure 5 As shown, the first driving mechanism 102 includes a base 10 and a telescopic mechanism 11; the telescopic mechanism 11 is disposed on the base 10, and the telescopic mechanism 11 can switch between an extended position and a shortened position; a portion of the moving slider 2 extends out of the brush receiving seat 1, and this portion is provided with a mating hole 9; the free end of the telescopic mechanism 11 is a wedge-shaped structure 12; when the telescopic mechanism 11 switches from the shortened position to the extended position, the telescopic mechanism 11 slides on the inner wall of the mating hole 9 through the inclined surface of the wedge-shaped structure 12, so as to pull the brush changing mechanism 101 from the clamping position to the releasing position.

[0069] Specifically, the explanation is based on the brush holder 1 being in a horizontal position. When the telescopic mechanism 11 switches from the shortened position to the extended position, the telescopic mechanism 11 switches between the extended and shortened positions in the vertical direction. Therefore, during the process of the telescopic mechanism 11 switching from the shortened position to the extended position, since there is a certain inclination angle between the inclined surface of the wedge structure 12 and the horizontal plane, as the telescopic mechanism 11 extends continuously, it can gradually move the moving slider 2 away from the brush receiving seat 1 while abutting the mating hole 9, thereby pulling the moving slider 2 away from the brush receiving seat 1. That is to say, during the process of the brush changing mechanism 101 switching from the clamping position to the releasing position, the moving slider 2 gradually moves away from the brush receiving seat 1, so that the brush 200 can be positioned in the brush receiving seat 1. Thus, after the telescopic mechanism 11 switches from the shortened position to the extended position, the clamping component clamps the brush receiving seat 1. In other words, this embodiment converts the vertical movement of the telescopic mechanism 11 into the horizontal movement of the moving slider 2, and converts the horizontal movement of the moving slider 2 into the rotational movement of the clamping component to achieve release and clamping.

[0070] To simplify the structure of this embodiment and further improve the efficiency of picking up and putting down the brush 200, the brush changing mechanism 101 further includes a first elastic element 13, one end of which is connected to the motion slider 2, and the other end is connected to the brush receiving and putting seat 1. In addition, the clamping assembly also includes a second elastic element 14 corresponding to the two clamping members 4, one end of which is connected to the clamping member 4, and the other end is connected to the brush receiving and putting seat 1.

[0071] In the embodiment, the active end of the telescopic mechanism 11 has only one slope, and on the basis of the first elastic member 13, the first elastic member 13 is deformed when the telescopic mechanism 11 is switched from the shortened position to the lengthened position, at which time the first elastic member 13 stores elastic potential energy, and after the telescopic mechanism 11 is switched from the lengthened position to the shortened position, the first elastic member 13 releases the elastic potential energy to push the moving slider 2 into the brush holder 1, so that the clamping assembly rotates in the opposite direction to achieve clamping of the brush 200, and after the slope of the wedge-shaped structure 12 is disengaged from the matching hole 9, the clamping assembly can be kept in the clamped state with the brush 200 by the continuous elastic force provided by the first elastic member 13, thereby better satisfying the use stability of the brush 200. On this basis, each second elastic member 14 acts on the corresponding clamping piece 4, and when the moving slider 2 is in the release position, the second elastic member 14 is deformed, at which time the second elastic member 14 stores elastic potential energy, so that when the moving slider 2 is in the clamping position, the second elastic member 14 releases the elastic potential energy, so that the clamping assembly better clamps the brush 200. It can be understood that in the embodiment, the cooperative relationship between the first elastic member 13 and the second elastic member 14 well satisfies the clamping requirements of the brush 200, so that the brush 200 better maintains use stability during taking and placing. In addition, in the embodiment, the extension direction of the first elastic member 13 is consistent with the movement path of the moving slider 2, and the extension direction of the second elastic member 14 is substantially perpendicular to the movement path of the moving slider 2, thereby satisfying the elastic force output requirements of the first elastic member 13 and the second elastic member 14. It can be understood that when the moving slider 2 is in the clamping position, the elastic force provided by the first elastic member 13 and the second elastic member 14 can be a compression force or a tensile force, and in order to simplify the structure and facilitate assembly, as an optimal choice, the embodiment maintains the elastic force output in the form of a compression force.

[0072] In the embodiment, as shown in Figure 5 The first driving mechanism 102 further includes a rotating mechanism 15 arranged on the base 10 and used for covering the telescopic mechanism 11 in the shortened position.

[0073] Therefore, in use of the embodiment, the rotating mechanism 15 needs to be driven to open before the telescopic mechanism 11 is driven to act, and it can be known that by locking the telescopic mechanism 11 in the shortened position through the rotating mechanism 15, misoperation can be well avoided.

[0074] As shown in Figure 1 and Figure 2As shown, in the present embodiment, the brush replacing assembly 100 further comprises a floating foot 103, the floating foot 103 having a pulling member 16; the brush holder 1 is provided with a connecting hole 17 matched with the pulling member 16; the pulling member 16 can drive the brush replacing mechanism 101 to move close to or away from the floating foot 103.

[0075] The floating foot 103 is provided with a pulling member 16 at opposite ends, therefore, the connecting hole 17 is arranged at both ends of the brush holder 1. When the pulling member 16 drives the brush holder 1 to move close to the floating foot 103, the brush holder 1 is actually attached to the floating foot 103, that is, at this time, the brush holder 1 is relatively fixedly connected to the floating foot 103, at this time, the position of the brush 200 is also relatively determined, thus better meeting the requirements of taking and placing the brush 200.

[0076] In addition, it should be noted that, in the present embodiment, the base 10 of the first driving mechanism 102 is arranged on the floating foot 103.

[0077] As shown in Figure 6 and Figure 7 In order to better use the present embodiment, a brush storage assembly 300 is further included, the brush storage assembly 300 is arranged on one side of the brush replacing assembly 100, the brush storage assembly 300 comprises a base 18, a moving seat 19 and a storage mechanism; the moving seat 19 is connected to the base 18 through a second driving mechanism, so as to switch the moving seat 19 between a waiting position and a taking and placing position; the storage mechanism is connected to the moving seat 19, for storing the brush 200; the storage mechanism is provided with a limiting member 20 for limiting the brush 200.

[0078] In the present embodiment, the moving seat 19 is driven by the second driving mechanism to produce relative movement with the base 18, so as to switch the moving seat 19 between the waiting position and the taking and placing position. Specifically, the waiting position refers to the position of the moving seat 19 placed on the base 18, and the taking and placing position refers to the predetermined position reached by the moving seat 19 driven by the second driving mechanism to move away from the base 18, that is, when the moving seat 19 is located at the waiting position, the damaged brush 200 on the storage mechanism can be replaced, so that the storage mechanism is repositioned with a new brush 200, when the moving seat 19 is located at the taking and placing position, the new brush 200 is picked up by an external mechanism for installation, and the damaged brush 200 can be placed on the storage mechanism by the brush replacing mechanism 101.

[0079] In the present embodiment, the inner side of the brush 200 has a groove matched with the limiting member 20, when the limiting member 20 abuts against the groove surface, the movement of the brush 200 is limited.

[0080] In the embodiment, the collecting mechanism comprises a collecting shaft 21 and a placing platform 22; the collecting shaft 21 is arranged in the inner cavity of the moving seat 19, one end of the collecting shaft 21 is detachably connected with the moving seat 19, and the other end of the collecting shaft 21 is provided with a positioning portion 23; the placing platform 22 is connected with the collecting shaft 21, and the placing platform 22 is located on the side of the positioning portion 23 close to the base 18.

[0081] Since the collecting shaft 21 is fixed in the inner cavity of the moving seat 19, the collecting shaft 21 can move along with the moving seat 19 under the driving of the second driving mechanism, so as to switch between the waiting position and the taking and placing position, thereby meeting the transfer requirement of the brush 200. The placing platform 22 can well place the brush 200. In the embodiment, the middle part of the brush 200 is a hole portion, and the positioning portion 23 is a protruding structure matched with the hole portion, so as to position the placing position of the brush 200. When the collecting shaft 21 is a stepped shaft, the protruding structure can be a part of the stepped shaft, and of course, can also be a component detachably connected with the end of the collecting shaft 21.

[0082] Therefore, in the embodiment, the limiting member 20 can be configured as a bead mechanism, that is, the limiting member 20 is a bead mechanism arranged along the circumferential outer wall of the positioning portion 23. It can be understood that the bead mechanism has a plurality of beads arranged in a circular array.

[0083] As shown in Figure 8 Generally, the bead mechanism can be composed of a fourth elastic member 24 and a steel bead 25, that is, the fourth elastic member 24 extends into the positioning portion 23, one end of the fourth elastic member 24 is fixedly connected in the positioning portion 23, and the other end of the fourth elastic member 24 is connected with the steel bead 25. Therefore, in the process of taking and placing the brush 200, the fourth elastic member 24 is deformed and compressed, so that the steel bead 25 sinks into the positioning portion 23 to avoid the movement of the brush 200. When the brush 200 is located on the placing platform 22, the fourth elastic member 24 returns to the normal state, and the steel bead 25 is matched with the groove arranged on the brush 200.

[0084] In order to better use the embodiment, the collecting mechanism further comprises a third elastic member 26, the third elastic member 26 is sleeved on the outside of the collecting shaft 21; the placing platform 22 is slidably connected with the collecting shaft 21, one end of the third elastic member 26 is connected with the placing platform 22, and the other end of the third elastic member 26 is connected with the moving seat 19.

[0085] When the brush changing mechanism 101 wants to pick up the brush 200 on the placing platform 22 or wants to place the brush 200 on the placing platform 22, the brush changing mechanism 101 continuously moves and presses the placing platform 22, so that the third elastic member 26 is compressed and deformed, so that the brush changing mechanism 101 can realize the movement of overstroke, thereby well realizing the movement buffering and well driving the movement of the bead mechanism relative to the positioning portion 23, so that the brush changing mechanism 101 well picks up the brush 200 or places the brush 200 on the placing platform 22.

[0086] In the embodiment, the second driving mechanism includes a linear cylinder 27, one end of the linear cylinder 27 is connected with the base 18, and the other end is connected with the movement seat 19. The second driving mechanism further includes a guide rod 28, one end of the guide rod 28 is connected with the movement seat 19, so that the movement seat 19 moves along the extension direction of the guide rod 28.

[0087] The linear cylinder 27 can drive the linear movement of the movement seat 19, and through the guidance of the guide rod 28, the movement seat 19 can reciprocate on the preset movement path. Further, the opposite ends of the movement seat 19 are provided with accommodating portions 29, all or part of the linear cylinder 27 is located in one of the accommodating portions 29, and all or part of the guide rod 28 is located in the other accommodating portion 29. That is, the linear cylinder 27 and the guide rod 28 are respectively located at the opposite ends of the movement seat 19.

[0088] Therefore, in the embodiment, the two ends of the movement seat 19 are respectively limited by the linear cylinder 27 and the guide rod 28, that is, the movement seat 19 can only reciprocate along the extension direction of the linear cylinder 27 and the extension direction of the guide rod 28, thereby better meeting the stability requirement of the movement of the movement seat 19.

[0089] In order to better use the embodiment, a sensing assembly is further included for detecting whether the movement seat 19 is located at the preset position of the base 18. Specifically, the sensing assembly includes a sensing plate 30 and a sensor 31; the sensing plate 30 is arranged on the movement seat 19; and the sensor 31 is arranged on the base 18 and is used for detecting the position of the sensing plate 30.

[0090] When the movement seat 19 is ejected, the brush changing mechanism 101 picks up or places the brush 200 on the placing platform 22, and then the movement seat 19 is reset to the preset position, that is, the position of the movement seat 19 placed on the base 18. That is, when the movement seat 19 is located at the preset position, the brush 200 on the placing platform 22 can be replaced more accurately, thereby ensuring the stability of the picking and placing of the brush 200. In the embodiment, the sensor 31 is an infrared sensor 31.

[0091] The above merely describes the preferred embodiments of the present application, and it should be pointed out that the above preferred embodiments should not be regarded as a limitation to the present application, and the protection scope of the present application should be defined by the scope of the claims. For those skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
