[0083] In summary, the entire process of "brush box 1 loading → carbon brush body 2 loading → wire arrangement → spring 3 loading → welding wire fixing → box closing → pulling test → carbon brush unloading" is fully automated to improve the assembly efficiency of carbon brushes.

[0084] In some embodiments, reference Figures 2 to 4 The mounting fixture 100 includes a base 110, a first clamping mechanism 120 and a stop block 130. A clamping hole 140 is provided at the front end of the base 110. The first clamping mechanism 120 is installed in the base 110. The first clamping mechanism 120 is located behind the clamping hole 140. The first clamping mechanism 120 is used to clamp the carbon brush body 2. The stop block 130 is slidably connected to the base 110. The stop block 130 is located above the clamping hole 140. The stop block 130 can be raised and lowered to open all the clamping holes 140 or block part of the clamping holes 140.

[0085] In the feeding stage of the brush box 1, the brush box 1 is fixed in the clamping hole 140 under the clamping of the brush box feeding mechanism 200, and in the feeding stage of the carbon brush body 2, the carbon brush body 2 is directly inserted into the brush box 1 under the clamping of the mechanism, and in the subsequent process of straightening the carbon brush body 2, the stop block 130 is used to prevent the brush box 1 from slipping out of the clamping hole 140. In addition, when the spring feeding mechanism 500 performs the spring 3 installation process, the stop block 130 can be raised to make room for the spring 3, and in the box closing process after welding and fixing, the stop block 130 can be raised so that the brush box 1 can completely and tightly close the end, and further, in the above-mentioned process of straightening the carbon brush body 2 In the embodiment, the clamping mechanism in the installation fixture 100 can clamp the end of the carbon brush body 2 away from the copper wire to prevent the carbon brush body 2 from slipping. When the spring 3 is installed, the spring 3 pushes the carbon brush body 2 to move toward the rear end of the installation fixture 100. At this time, the clamping mechanism needs to make room for the carbon brush body 2 to move. After the spring 3 is inserted into the brush box 1, the clamping mechanism is used to re-clamp the carbon brush body 2. The clamping hole 140 can effectively constrain the position of the brush box 1. For the carbon brush body 2 that can move in the brush box 1, the clamping mechanism is used to constrain the position from the end away from the processing mechanism, thereby ensuring the position stability of the carbon brush body 2 and the brush box 1 during online processing, which is convenient for the application of multi-process automatic processing production lines.

[0086] Furthermore, the clamping hole 140 is used to clamp the brush box 1. Therefore, the size of the clamping hole 140 should be consistent with the size of the brush box 1, and the brush box 1 should be clamped. In order to avoid interference between the brush box 1 and the clamping hole 140 when the brush box 1 is inserted, in some embodiments, a first clamping portion 141 and a second clamping portion 142 are provided on the base 110. The first clamping portion 141 is fixedly connected to the base 110, and the second clamping portion 142 is slidably connected to the base 110 to approach or move away from The first clamping part 141 is provided with a first clamping groove, and the second clamping part 142 is provided with a second clamping groove. The first clamping groove cooperates with the second clamping groove to form a clamping hole 140. When the brush box 1 is loaded, the clamping hole 140 is enlarged by sliding the second clamping part 142, and the brush box 1 is inserted into the enlarged clamping hole 140. Finally, the second clamping part 142 is reset, so that the second clamping part 142 cooperates with the first clamping part 141 to clamp the brush box 1. Preferably, the first clamping mechanism 120 includes a first pneumatic finger 121 and a first clamping jaw 122. The first pneumatic finger 121 is fixedly connected to the base 110. Two first clamping jaws 122 are provided, and the two first clamping jaws 122 are respectively fixed to the two driving ends of the first pneumatic finger 121. The first pneumatic finger 121 drives the two first clamping jaws 122 to move away from or approach each other, and there is a clamping gap 123 between the two first clamping jaws 122. The first pneumatic finger 121 drives the two first clamping jaws 122 to move away from or toward each other, and a clamping gap 123 is formed between the two first clamping jaws 122. The first pneumatic finger 121 drives the first clamping jaws 122 to separate and approach, so that the clamping gap 123 is expanded or narrowed to release space for the carbon brush to move, or to clamp the carbon brush.

[0087] Specifically, the base 110 is provided with a slide rail 111, the second clamping portion 142 and the slide rail 111 are slidably connected, and the base 110 is fixedly connected with a displacement driving mechanism 150, the displacement driving mechanism 150 includes a displacement cylinder 151 and a roller 152, the roller 152 is pivotally mounted on the second clamping portion 142, the driving end of the displacement cylinder 151 can be extended and abutted against the roller 152, and the driving end of the displacement cylinder 151 is located between the center of the roller 152 and the outermost side close to the first clamping portion 141. Preferably, in order to realize automatic resetting of the second clamping portion 142, a second resetting spring (not shown in the figure) is arranged between the second clamping portion 142 and the base 110. When the driving end of the displacement cylinder 151 is extended and abuts against the surface of the roller 152, the rotatable roller 152 can slide along the driving end of the displacement cylinder 151 and drive the second clamping portion 142 away from the first clamping portion 141, so that the clamping hole 140 is expanded; when the driving end of the displacement cylinder 151 is reset, the second clamping portion 142 will be reset under the action of the second resetting spring, and cooperate with the first clamping portion 141 to clamp the brush box 1 located in the clamping hole 140.

[0088] In some embodiments, reference Figure 4 The carbon brush automatic assembly mechanism also includes a lifting mechanism 160, which is used in conjunction with the installation fixture 100. The lifting mechanism 160 includes a first lifting cylinder 161 and a first push rod 162. The driving end of the first lifting cylinder 161 is set upward; the first push rod 162 is fixedly connected to the driving end of the first lifting cylinder 161, and the first push rod 162 is located below the stop block 130. The first push rod 162 can rise and abut against the bottom of the stop block 130. Among them, the stop block 130 is connected to the first lifting block 131, and the first lifting block 131 is slidably connected to the base 110 so that the first lifting block 131 can slide up and down on one side of the base 110 to realize the up and down lifting of the stop block 130. In the above-mentioned steps of loading the brush box 1, loading the carbon brush body 2, loading the spring 3 and closing the box, it is necessary to cooperate with the lifting mechanism to drive the first lifting block 131. In order to facilitate the rapid resetting of the stop block 130 to avoid affecting the next process, in some embodiments, a first reset spring (not shown in the figure) is arranged between the first lifting block 131 and the bottom of the base 110, and the first reset spring drives the first lifting block 131 to descend.

The second clamping mechanism 410 is located below the mounting fixture 100 and is used to clamp the portion of the carbon brush body 2 protruding from the mounting fixture 100. The first clamping mechanism 420 is located on the side of the mounting fixture 100 where the carbon brush body 2 is installed. The first clamping mechanism 420 is used to clamp the copper wire of the carbon brush body 2. The linear drive mechanism 430 is connected to the first clamping mechanism 420, and the linear drive mechanism 430 is used to drive the first clamping mechanism 420 to approach the mounting fixture 100 or to move away from the mounting fixture 100 along a straight line. The rotation drive mechanism 440 is connected to the first clamping mechanism 420, and the rotation drive mechanism 440 is used to drive the first clamping mechanism 420 to pivot. Specifically, as a detailed description of the working process of the wire management mechanism 400, it is explained in the form of steps:

[0094] The wire management mechanism 400 has the following working process:

[0095] Wire management step 1, move the installation fixture 100 to above the second clamping mechanism 410 and correspond to the first clamping mechanism 420;

[0096] Wire arrangement step 2: using the second clamping mechanism 410 to clamp the portion of the carbon brush body 2 protruding from the mounting fixture 100 to fix the position of the carbon brush body 2;

[0097] Wire arrangement step 3, the linear drive mechanism 430 drives the first clamping mechanism 420 to feed forward;

[0098] Wire arrangement step 4: using the first clamping mechanism 420 to clamp the copper wire of the carbon brush body 2;

[0099] Wire arrangement step 5, the linear drive mechanism 430 and the rotary drive mechanism 440 are started synchronously, the linear drive mechanism 430 drives the first clamping jaw mechanism 420 to retreat, and at the same time, the rotary drive mechanism 440 drives the first clamping jaw mechanism 420 to pivot;

[0100] Wire arrangement step 6: After completing the wire arrangement process of the carbon brush body 2 on the current installation fixture 100, the current installation fixture 100 is moved out of the position and step 1 is repeated.

[0101] Preferably, the second clamping mechanism 410 includes a second pneumatic finger 411 and a second clamping jaw 412, and the second clamping jaw 412 is fixedly connected to the two driving ends of the second pneumatic finger 411. The two driving ends of the second pneumatic finger 411 can drive the two second clamping jaws 412 to open or merge, thereby releasing or clamping the carbon brush body 2 of the brush box 1 in the installation fixture 100, so that the first clamping jaw mechanism 420 can organize the copper wire of the carbon brush body 2. Furthermore, a first lifting mechanism 413 is connected to the bottom of the second clamping mechanism 410, and the first lifting mechanism 413 is used to drive the second clamping mechanism 410 to move up and down. The second clamping mechanism 410 that can be lifted and lowered can avoid motion interference between the second clamping mechanism 410 and the turntable 10 or the installation fixture 100.

[0102] Preferably, the first clamping mechanism 420 includes a third pneumatic finger 421 and a third clamping jaw 422 , and the third clamping jaw 422 is fixedly connected to two driving ends of the third pneumatic finger 421 . The two driving ends of the third pneumatic finger 421 can drive the two third clamping jaws 422 to open or merge, thereby releasing or clamping the copper wire of the carbon brush body 2. After the two third clamping jaws 422 cooperate and clamp the copper wire, the copper wire is straightened through the coordinated control of the linear drive mechanism 430 and the rotation drive mechanism 440 to complete the wire sorting process. Furthermore, a curved hook portion 4221 is provided at the front end of the third clamping jaw 422. The hook portions 4221 of the two third clamping jaws 422 are bent relative to each other. The inwardly bent hook portion 4221 can form an avoidance area between the two third clamping jaws 422. After the two hook portions 4221 cooperate to clamp the copper wire, the front end of the copper coin can be in the avoidance area and will not be clamped, thereby avoiding the clamping area being too large and causing damage to the copper wire, thereby further improving the clamping effect. A third clamping groove 4222 is provided at the opposite end of the hook portion 4221. The third clamping groove 4222 is used to embed the copper wire of the carbon brush body 2.

[0103] In some embodiments, reference Fig.12The spring feeding mechanism 500 includes a sleeve 510, a linear feeding mechanism 520 and a pushing mechanism 530. The middle part of the sleeve 510 is used to sleeve the copper wire of the carbon brush body 2, and the outer part of the sleeve 510 is used to sleeve the spring 3. The sleeve 510 and the clamping hole 140 are correspondingly arranged; the linear feeding mechanism 520 and the sleeve 510 are fixedly connected, and the linear feeding mechanism 520 is used to drive the sleeve 510 to approach the installation fixture 100 or move away from the installation fixture 100; the pushing mechanism 530 is telescopically arranged on the linear feeding mechanism 520, and the telescopic path of the pushing mechanism 530 is the same as the length direction of the sleeve 510, and the pushing mechanism 530 is used to push out the spring 3 sleeved on the sleeve 510.

[0104] In actual use, the mounting fixture 100 is driven by the turntable 10 to move to a position corresponding to the sleeve 510, so that the sleeve 510 can be aligned with the brush box 1 in the clamping hole 140. The stopper 130 in the mounting fixture 100 partially covers the clamping hole 140, so that the brush box 1 completely located in the clamping hole 140 will not fall out of the mounting fixture 100, and the carbon brush body 2 in the brush box 1 is partially exposed outside the mounting fixture 100. The purpose is to facilitate the processing of the previous steps. In the step of installing the spring 3, the brush to be installed is first sleeved on the sleeve 510. Spring 3, and use the lifting mechanism 160 to lift the stop block 130 on the installation fixture 100, open the complete clamping hole 140, and then move the sleeve 510 to the installation fixture 100 through the linear feed mechanism 520, so that the sleeve 510 is sleeved outside the copper wire, and then use the pushing mechanism 530 to push the spring 3 on the sleeve 510 into the brush box 1. It should be emphasized that when the pushing mechanism 530 pushes the spring 3 into the brush box 1, it will also push the carbon brush body 2 and the spring 3 into the brush box 1 at the same time, waiting for the subsequent process to further assemble and process the brush box 1.

[0105] Furthermore, the spring feeding mechanism 500 further includes a positioning mechanism 540, which is disposed between the mounting fixture 100 and the sleeve 510. The positioning mechanism 540 is used to position the copper wire of the carbon brush body 2. After the mounting fixture 100 is moved to a position corresponding to the sleeve 510, the positioning mechanism 540 is first used to preliminarily constrain the copper wire to ensure that the sleeve 510 can accurately sleeve the copper wire. The positioning mechanism 540 includes a rotating seat 541 and a swing arm 542, one end of the swing arm 542 is rotatably connected to the rotating seat 541, and the other end is provided with a V-shaped positioning groove 5421. The positioning groove 5421 is used to embed the copper wire to constrain the position of the copper wire.

[0106] In some embodiments, the pushing mechanism 530 includes a first mounting seat 531, a third slider 532 and a pushing block 533. The first mounting seat 531 is connected to the linear feed mechanism 520 and is driven to move by the linear feed mechanism 520. The sleeve 510 is fixed at the front end of the first mounting seat 531. The first mounting seat 531 is provided with a first track 5311. The first track 5311 and the sleeve 510 are arranged parallel to each other. The third slider 532 is slidably connected to the first track 5311. One end of the pushing block 533 is sleeved on one end of the sleeve 510 close to the first mounting seat 531 and is slidably connected to the sleeve 510. The other end of the pushing block 533 is fixedly connected to the third slider 532. During actual operation, when the sleeve 510 is completely sleeved with the copper wire, the third slider 532 slides on the first mounting seat 531 and moves along the length direction of the sleeve 510, pushing the spring 3 sleeved on the sleeve 510 forward and abutting against the carbon brush body 2 in the brush box 1. The spring 3 pushes the carbon brush body 2 and enters the brush box 1 together with the carbon brush body 2 to complete the assembly. The third slider 532 is connected to a reciprocating cylinder, which is used to drive the third slider 532 to slide back and forth.

[0107] In some embodiments, the linear feed mechanism 520 includes a sliding seat 521, a linear feed motor 522 and a screw 523. The sliding seat 521 is provided with a second track, and the second track is slidably connected with a fourth slider 524. The linear feed motor 522 is fixed to an end of the second track away from the mounting fixture 100. The screw 523 is pivotally mounted on the sliding seat 521. The screw 523 and the linear feed motor 522 are fixedly connected and driven to rotate by the linear feed motor 522. The fourth slider 524 and the screw 523 are threadedly matched. The linear feed mechanism 520 is used to drive the sleeve 510 forward or backward, wherein the linear feed motor 522 drives the screw 523 to pivot and converts the rotational motion of the screw 523 into the linear motion of the fourth slider 524 on the sliding seat 521.

[0108] In some embodiments, reference Figure 14 to Figure 15The wire welding mechanism 600 includes a spot welding machine 610 and a clamping mechanism 620. The spot welding machine 610 is used to weld and fix the copper wire of the carbon brush body 2 and the inner side of the end face of the brush box 1. The clamping mechanism 620 includes a fifth pneumatic finger 621 and two clamping blocks 622. One end of the clamping block 622 is fixedly connected to one of the driving ends of the fifth pneumatic finger 621, and the other end is provided with a clamping groove 6221. The clamping grooves 6221 of the two clamping blocks 622 are arranged opposite to each other. Specifically, the turntable 10 moves the mounting fixture 100 to a position corresponding to the wire welding mechanism 600. At this time, the copper wire of the carbon brush body 2 and the end face of the brush box 1 are fixedly connected to each other. In the welding area of ​​the spot welding machine 610, two positioning grooves 6221 are respectively abutted against the two sides of the end face to position the end face, and then the copper wire and the end face are fixed by internal welding using the spot welding machine 610. It should be emphasized that the positioning mechanism 620 is provided with a second lifting mechanism 623 for lifting the positioning mechanism 620. Specifically, when the turntable 10 moves the mounting fixture 100 to a position corresponding to the welding wire mechanism 600, the second lifting mechanism 623 is used to lift the positioning mechanism 620 and constrain the position of the brush box 1 to avoid position interference between the brush box 1 on the mounting fixture 100 and the positioning mechanism 620.

[0109] In some embodiments, reference Figure 16 to Figure 17 The box closing mechanism 700 includes a lifting drive mechanism 710 and a bending member 720. The bending member 720 is installed at the upper end of the lifting drive mechanism 710 and is driven up and down by the lifting drive mechanism 710. The bending member 720 can rise and abut against the end surface of the brush box 1 to bend the end surface of the brush box 1 and cover the end of the brush box 1.

[0110] In the actual process of closing the box, the mounting fixture 100 fixes the entire brush box 1 to prevent the position of the brush box 1 from being offset, and then the end face located below is bent by the rising bending member 720 so that the end face covers the end of the brush box 1, completing the closing process. The entire working process is fully automated, greatly improving efficiency. Among them, the bending member 720 is a pivotable rolling wheel, and the lifting drive mechanism 710 is a second lifting cylinder. The driving end of the second lifting cylinder is fixedly connected with a second mounting seat 730, and the rolling wheel is pivotally mounted on the second mounting seat 730. The second lifting cylinder drives the second mounting seat 730 to rise, and the second mounting seat 730 drives the rolling wheel located at the top of the second mounting seat 730 to rise, and the rolling wheel and the end face of the brush box 1 are abutted. As the rolling wheel continues to rise, the rolling wheel squeezes the end face, so that the end face is bent and covers the end face of the brush box 1. Specifically, the front end of the rolling wheel close to the second mounting seat 730 can fit the end face of the brush box 1, so that the end face of the brush box 1 can tightly cover the end of the brush box 1.

[0111] It should be mentioned that a spring 3 is installed between the brush box 1 and the carbon brush body 2 in the mounting fixture 100. When the mounting fixture 100 clamps the carbon brush body 2, the brush box 1 at the front end of the mounting fixture 100 is easily extended out of the clamping hole 140 under the elastic force of the spring 3. For this reason, the stop block 130 is blocked above the clamping hole 140 before the box closing process. Furthermore, due to the existence of the stop block 130, when the end face of the brush box 1 is bent, the end face will fit with the stop block 130, and cannot directly fit and close with the end of the brush box 1. In order to ensure the end The surface can cover the end of the brush box 1. The second mounting seat 730 includes a fixed seat 731 and a swing seat 732. The fixed seat 731 is fixedly connected to the driving end of the second lifting cylinder. One end of the swing seat 732 is rotatably connected to one end of the fixed seat 731 away from the second lifting cylinder, and the other end is rotatably connected to a rolling wheel. Driven by external force, the swingable swing seat 732 can drive the rolling wheel to press against the end face, so that the end face is close to the end of the brush box 1. In the process of the rolling wheel swinging toward the mounting fixture 100, it is necessary to use the lifting mechanism 160 to lift the stop block 130 in the mounting fixture 100.

[0112] In order to drive the rolling wheel to press against the brush box 1 by external force, the box closing mechanism 700 further includes a pushing mechanism 740, which is used to drive the swing seat 732 to squeeze toward the installation fixture 100. Specifically, the pushing mechanism 740 includes a pushing cylinder 741 and a pushing rod 742, and the pushing cylinder 741 and the installation fixture 100 are correspondingly arranged; the pushing rod 742 is fixedly connected to the driving end of the pushing cylinder 741, and can extend or retract toward the installation fixture 100. The pushing rod 742 can directly abut against the rolling wheel or the swing seat 732 under the drive of the pushing cylinder 741, and push the swing seat 732 to swing. In order to achieve the reset of the swing seat 732 after the pushing is completed, in some embodiments, a reset mechanism (not shown in the figure) is arranged between the swing seat 732 and the fixed seat 731, and the reset mechanism drives the swing seat 732 to swing in the direction away from the installation fixture 100, and the reset mechanism is an elastic member.

[0113] In the above scheme, the swing seat 732 can be reset under the drive of the reset mechanism. In order to enable the swing seat 732 to reset to the same position, a stop portion 7311 is provided at the upper end of the fixed seat 731. The stop portion 7311 can abut and cooperate with the swing seat 732 to keep the swing seat 732 in a vertical state.

[0114] In some embodiments, reference Fig.18The pulling mechanism 800 includes a clamping mechanism 810 and a pulling spring 820. The clamping mechanism 810 and the mounting fixture 100 are correspondingly arranged and used to clamp the front end of the brush box 1. The clamping mechanism 810 can move in a straight line to approach or move away from the mounting fixture 100; the pulling spring 820 has a rebound force. When the pulling spring 820 is in an extended state, the pulling spring 820 can drive the clamping mechanism 810 to move in a direction away from the mounting fixture 100.

[0115] In actual processing, the brush box 1 located in the installation fixture 100 is clamped by the clamping mechanism 810, and at the same time, the first clamping mechanism 120 of the installation fixture 100 clamps the portion of the carbon brush body 2 protruding from the brush box 1, and then the tensile spring 820 is stretched to a fixed length, and the tensile spring 820 generates a pulling force on the clamping mechanism 810, and indirectly pulls the brush box 1, so as to stably confirm whether the brush box 1 and the carbon brush body 2 are tightly connected, thereby improving the inspection efficiency of the entire product.

[0116] In some embodiments, the pulling mechanism 800 also includes a base 830, which is slidably connected to a fifth slider 831. The clamping mechanism 810 and the base 830 are slidably connected, and the sliding directions of the clamping mechanism 810 and the fifth slider 831 are consistent. A second push rod 8311 is provided at the front end of the fifth slider 831. One end of the pulling spring 820 is fixedly connected to the fifth slider 831, and the other end is fixedly connected to one end of the clamping mechanism 810 away from the installation fixture 100. The second push rod 8311 can abut against the clamping mechanism 810 to push the clamping mechanism 810 to slide.

[0117] Specifically, the position of the base 830 remains unchanged, and the fifth slider 831 moves forward, which can push the clamping mechanism 810 to feed toward the installation fixture 100, so that the clamping mechanism 810 can clamp the brush box 1. Specifically, the clamping hole 140 of the installation fixture 100 is first expanded to cancel the clamping of the brush box 1 by the installation fixture 100. At the same time, the first clamping mechanism 120 of the installation fixture 100 clamps the part of the carbon brush body 2 protruding from the brush box 1, and then the clamping mechanism 810 is used to clamp the brush box 1. After clamping, the fifth slider 831 returns to its original position, and at the same time, the tensile spring 820 is lengthened, and a tensile force is applied to the brush box 1 through the tensile spring 820 for testing. Specifically, in order to ensure that the stroke of the fifth slider 831 remains unchanged, the tensile spring 820 is ensured to be elongated each time. The degree is constant. In some embodiments, a first stop plate 832 is provided at one end of the base 830 away from the clamping mechanism 810. The first stop plate 832 can abut against the fifth slider 831 to constrain the position of the fifth slider 831. Furthermore, in order to further ensure that the length of the tensile spring 820 is consistent during the test, preferably, the clamping mechanism 810 includes a sixth slider 811, a fourth pneumatic finger 812 and a fourth clamp 813. The sixth slider 811 is slidably connected to the base 830; the cylinder body of the fourth pneumatic finger 812 is fixed to the end of the sixth slider 811 away from the fifth slider 831; two fourth clamps 813 are provided, and the two fourth clamps 813 are respectively fixedly connected to the two driving ends of the fourth pneumatic finger 812. The two fourth clamping jaws 813 are driven by the fourth pneumatic finger 812 to clamp the brush box 1, wherein, in some embodiments, a second stop plate 833 is provided at one end of the base 830 close to the sixth slider 811, and the second stop plate 833 can abut against the sixth slider 811 to restrict the stroke of the sixth slider 811. Therefore, when the sixth slider 811 moves toward the installation fixture 100, the second stop plate 833 can be used to limit the moving position, and when the fifth slider 831 moves away from the installation fixture 100, the first stop plate 832 is used to limit the moving position, thereby ensuring that the length of the stretched spring 820 is consistent each time.

[0118] In some embodiments, in the carbon brush discharging process of step 8, refer to Fig.13The discharging mechanism 900 includes a discharging rod 910 and a material receiving box 920. The material receiving box 920 is arranged on one side of the turntable 10 and is arranged corresponding to the mounting fixture 100. The material receiving box 920 is located below the clamping hole 140. The discharging rod 910 is telescopically arranged at one end of the mounting fixture 100 away from the material receiving box 920. The discharging rod 910 is connected to a discharging cylinder 911. The discharging cylinder 911 drives the discharging rod 910 to extend. The discharging rod 910 can extend into the clamping gap 123 of the first clamping mechanism 120, and abuts against the carbon brush body 2 to push the entire carbon brush out of the clamping hole 140. Under the action of gravity, the carbon brush falls into the material receiving box 920 to complete the collection. When performing this process, correspondingly, the displacement driving mechanism 150 is required to expand the clamping hole 140 to facilitate the pushing out of the carbon brush.

[0119] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
