However, manual installation is inefficient, and the accuracy and consistency of carbon brush assembly are difficult to guarantee, affecting the quality of the motor. Therefore, there is an urgent need for equipment that can automate the installation of carbon brushes. Summary of the Invention

The two ends of the drive lead screw are respectively threadedly connected to two clamping sliding seats, and the thread directions at the connection points between the two ends of the drive lead screw and the two clamping sliding seats are opposite. The two clamping mechanisms are respectively installed on the two clamping sliding seats. The lead screw drive mechanism is used to drive the drive lead screw to rotate so that the two clamping sliding seats move closer to each other or further away from each other.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1 As shown, this invention provides a carbon brush installation device, including a rotary feeding device 1, a rotary feeding platform 2, a carbon brush installation device 3, a carbon brush installation positioning device 4, a carbon brush movable end installation device 5, and a linear transfer device (not shown in the figure). The rotary feeding device 1 is used to transfer the carbon brushes onto the rotary feeding platform. The carbon brush installation device 3 is used to simultaneously clamp a pair of carbon brushes placed on the rotary feeding platform and transfer them to both sides of the motor housing, inserting the heads of the carbon brushes into the motor housing. The carbon brush installation positioning device 4 is disposed between the carbon brush installation device 3 and the carbon brush movable end installation device 5, used to embed the movable ends of the carbon brushes and provide sliding guidance for the linear transfer process of the motor. The carbon brush movable end installation device 5 is used to clamp and position the movable ends of the carbon brushes and then insert the movable ends of the carbon brushes into the motor housing. The linear transfer device is used to perform linear transfer of the motor.

[0040] The carbon brush is transferred to the rotary feeding platform 2 by the rotary feeding device 1. The carbon brush installation device 3 picks up the carbon brush from the rotary feeding platform 2 and inserts it into the motor housing. The linear transfer device transfers the motor to the carbon brush movable end installation device 5. During the transfer, the carbon brush installation positioning device 4 can position the carbon brush movable end. The carbon brush movable end installation device 5 inserts the carbon brush movable end into the motor housing to complete the assembly of the carbon brush and the motor housing. This realizes the automated installation of motor carbon brushes and greatly improves production efficiency.

[0041] In this embodiment, the linear transfer device uses a conveyor belt, with the motor placed on the fixture 6, and the fixture 6 is conveyed forward via the conveyor belt.

[0042] In this embodiment, carbon brushes are fed through a linear conveyor track, and the carbon brushes at the feed point are sequentially transferred to the top of the rotary unloading platform 2 by the rotary feeding device 1.

[0043] Combination Figure 2 and 3As shown, the rotary feeding device 1 further includes a rotary feeding bracket 11 and a feeding mechanism 12. The feeding mechanism 12 is mounted on the rotary feeding bracket 11 and can move vertically relative to the rotary feeding bracket 11. The feeding mechanism 12 includes a vertical slide 121, a rotating frame 122, a primary rotary drive element 123, and a clamping element 124. The vertical slide 121 is vertically slidably connected to the rotary feeding bracket 11, and the rotating frame 122 is rotatably connected to the vertical slide 121. The primary rotary drive element 123 is used to drive the rotating frame 122 to rotate. A pair of clamping elements 124 symmetrically distributed with respect to its rotation center are mounted on the rotating frame 122. The clamping elements 124 are used to clamp the carbon brush.

[0044] The rotating frame 122 is driven to rotate by the primary rotating drive element 123. The rotating frame 122 can drive the clamping element 124 to complete a 180° rotation. The two clamping elements 124 can alternately clamp the carbon brush and transfer it to a symmetrical position, realizing continuous transfer of the carbon brush. The carbon brush transfer efficiency is high, which improves the installation efficiency of the carbon brush.

[0045] Furthermore, the rotary material handling bracket 11 is equipped with a main rotary drive element 111 and a lifting screw 112. The lifting screw 112 passes through the vertical slide block 121 and is threadedly connected to the vertical slide block 121. The main rotary drive element 111 is used to drive the lifting screw 112 to rotate. Preferably, the rotary material handling bracket 11 is equipped with at least two parallel vertical guide rails 113. The vertical slide block 121 is engaged with the vertical guide rails 113 and can slide along the vertical guide rails 113. In this embodiment, both the primary rotary drive element 123 and the main rotary drive element 111 are motors. The lifting screw 112 is connected to the output shaft of the main rotary drive element 111 and rotates with the output shaft.

[0046] A motor drives the lifting screw 112 to rotate. Through the threaded connection between the lifting screw 112 and the vertical slide 121, the vertical slide 121 moves up and down along the vertical guide rail 113 as the lifting screw 112 rotates. The vertical slide 121 then drives the rotating frame 122 to move up and down. Because the lifting screw 112 and the vertical slide 121 are threadedly connected, they can self-lock in the vertical direction, preventing the vertical slide 121 from shifting due to gravity and affecting the accuracy of the clamping element 124 in holding the carbon brush. Furthermore, the threaded drive method makes the transmission more stable and accurate, further improving the accuracy of the clamping element 124 in holding the carbon brush.

[0047] Furthermore, the rotating material handling bracket 11 is provided with two bearing seats 114 spaced apart along its height direction, the vertical slide block 121 is located between the two bearing seats 114, and the two ends of the lifting screw 112 are respectively connected to the bearings in the two bearing seats 114. Preferably, the two ends of the vertical guide rail 113 extend to the upper and lower bearing seats 114 respectively.

[0048] On the one hand, the bearing in the bearing housing 114 is connected to the lifting screw 112. The upper and lower bearing housings 114 can provide positioning for the lifting screw 112, preventing the lifting screw 112 from swinging during rotation and improving the stability when the lifting screw 112 is linked with the vertical slide 121. On the other hand, the upper and lower bearing housings 114 can also provide sliding limit for the vertical slide 121 in the vertical direction, controlling the movement stroke of the vertical slide 121.

[0049] Furthermore, a lifting position sensing plate 115 is installed on the vertical slide 121, and a lifting position sensing element 116 is installed on the rotating material handling bracket 11. The lifting position sensing element 116 is used to sense and identify the lifting position sensing plate 115. In this embodiment, the lifting position sensing plate 115 is an L-shaped thin sheet, and the lifting position sensing element 116 is preferably a photoelectric switch. Utilizing the principle of photosensitive sensing, when the lifting position sensing plate 115 reaches the photoelectric switch, it can send an electrical signal back to the control center to control the lifting adjustment of the vertical slide 121 in real time, ensuring that the clamping element 124 reaches the designated position and improving the accuracy of the clamping element 124 when clamping the carbon brush.

[0050] Furthermore, the rotating material handling bracket 11 is provided with an adjustment rail 117 along its height direction, and the lifting position sensing element 116 is mounted on the adjustment rail 117 and can be moved and adjusted relative to the adjustment rail 117. Preferably, the lifting position sensing element 116 is fixed to the adjustment rail 117 by screws, and the lifting position sensing element 116 can be fixed at a specified height position on the adjustment rail 117 as needed.

[0051] By adjusting the height of the lifting position sensing element 116, the recognition positions of the lifting position sensing plate 115 and the lifting position sensing element 116 are changed, thereby changing the stopping position of the clamping element 124, which meets the clamping needs of different products, is convenient to adjust, and has higher applicability.

[0052] Furthermore, a pair of secondary rotary drive elements 125 are mounted on the rotating frame 122. The secondary rotary drive elements 125 are arranged in a one-to-one correspondence with the clamping elements 124 and are used to drive the corresponding clamping elements 124 to rotate relative to the rotating frame 122. Preferably, the secondary rotary drive elements 125 are motors.

[0053] Since the carbon brush head is a carbon block and the movable end of the tail is a spring and a metal plate, when the carbon brush is transferred to the rotary feeding mechanism, the head faces forward and the spring and metal plate are located at the rear. After the clamping element 124 clamps the carbon brush, the first-stage rotary drive element 123 drives the rotary frame 122 to rotate. At this time, the carbon brush rotates 180° and its orientation changes. By setting the second-stage rotary drive element 125, the clamping element 124 is driven to rotate 180°, so that the orientation of the carbon brush is restored to the initial state, which facilitates the subsequent installation of the carbon brush.

[0054] Furthermore, the drive shaft of the secondary rotary drive element 125 is connected to the clamping element 124 and is used to drive the clamping element 124 to rotate. A secondary sensing plate 126 is installed on the circumferential side wall of the drive shaft of the secondary rotary drive element 125. A secondary sensing element 127 is installed on the rotating frame 122. The secondary sensing element 127 is used to sense and identify the secondary sensing plate 126. The secondary sensing element 127 is preferably a photoelectric switch. The secondary sensing plate 126 is an L-shaped thin plate.

[0055] The photoelectric switch is used to identify the secondary sensor 126, ensuring that the clamping element 124 rotates to a preset angle, ensuring that the clamping element 124 can accurately clamp and transfer the carbon brush, and achieving precise control over the transfer of the carbon brush.

[0056] Furthermore, the drive shaft of the primary rotary drive element 123 is connected to the rotating frame 122 and is used to drive the rotating frame 122 to rotate. A primary sensing plate 128 is installed on the circumferential sidewall of the drive shaft of the primary rotary drive element 123, and a primary sensing element 129 is installed on the vertical slide 121. The primary sensing element 129 is used to sense and identify the primary sensing plate 128. The primary sensing element 129 is a photoelectric switch, and the primary sensing plate 128 is an L-shaped thin plate.

[0057] By using a photoelectric switch to identify the primary sensor 128, the rotation angle of the rotating frame 122 is precisely controlled, thereby ensuring the accuracy of the rotation angle of the clamping element 124.

[0058] In this embodiment, the clamping element 124 is a pneumatic gripper, which controls the opening and closing of the clamping plates through pneumatic means to clamp the carbon brush, enabling pick-and-place and high transfer efficiency.

[0059] Combination Figure 4As shown, the rotating feeding platform 2 further includes a fixed platform 21, a rotating platform 22, and a rotating drive mechanism 23. The rotating platform 22 is rotatably connected to the fixed platform 21. Specifically, the rotating platform 22 is installed above the fixed platform 21. The rotating drive mechanism 23 is used to drive the rotating platform 22 to rotate relative to the fixed platform 21. The rotating drive mechanism 23 is preferably a servo motor. The rotating platform 22 is provided with at least four placement slots 221 for placing carbon brushes in a centrally symmetrical manner. In this embodiment, the rotating platform 22 is provided with four placement slots 221, which are arranged in a cross shape.

[0060] Preferably, a rotation sensing plate 24 is connected to the rotating platform 22, and a rotation sensing element 25 is provided on the fixed platform 21. The rotation sensing element 25 is used to sense and identify the rotation sensing plate 24. The rotation sensing element 25 is preferably a photoelectric switch, and the rotation sensing plate 24 is an L-shaped thin sheet. By sensing the rotation sensing plate 24 through the photoelectric switch, the rotation angle of the rotating platform 22 can be precisely controlled, ensuring that the carbon brush can be accurately placed in the placement slot 221.

[0061] Furthermore, the rotating feeding platform and the carbon brush mounting device 3 are positioned at a 90° angle relative to the rotating unloading platform 2. With this arrangement, when transferring carbon brushes, the placement of the carbon brush by the rotating feeding platform and the clamping of the carbon brush by the carbon brush mounting device 3 do not interfere with each other. Moreover, the carbon brush mounting device 3 can simultaneously clamp two carbon brushes, achieving synchronous installation of both and improving installation efficiency.

[0062] Combination Figures 5 to 9 As shown, the carbon brush mounting device 3 further includes a fixed bracket 31, a horizontal sliding mechanism 32, a vertical sliding mechanism 33, an opposing sliding mechanism 34, and a clamping mechanism 35. The horizontal sliding mechanism 32 is slidably connected to the fixed bracket 31 in the horizontal direction; the vertical sliding mechanism 33 is slidably connected to the horizontal sliding mechanism 32 in the vertical direction; two clamping mechanisms 35 are provided and are used to clamp the carbon brushes respectively; the opposing sliding mechanism 34 is mounted on the vertical sliding mechanism and connected to the clamping mechanism 35, and is used to drive the two clamping mechanisms 35 to move in opposite directions and insert the carbon brushes into the motor housing. In this embodiment, the clamping mechanism 35 is preferably a pneumatic gripper.

[0063] The horizontal sliding mechanism 32 can be used to change the position of the clamping mechanism 35 in the horizontal direction to transfer the carbon brush horizontally. The vertical sliding mechanism 33 can be used to change the vertical position of the clamping mechanism 35 to pick up and put in the carbon brush. The opposing sliding mechanism 34 can be used to move the two clamping mechanisms 35 in opposite directions, so that the carbon brush is inserted into the slots on both sides of the motor housing, thus realizing the installation of the carbon brush. The automation level is high, ensuring the consistency of carbon brush installation and improving the efficiency of carbon brush installation.

[0064] In this embodiment, the horizontal sliding mechanism 32 includes a horizontal sliding seat 321, and a sliding drive mechanism 322 is provided on the fixed bracket 31. The sliding drive mechanism 322 includes a driving wheel 3221, a driven wheel 3222, a drive motor (not shown in the figure), and a synchronous belt 3223. The drive motor is connected to the driving wheel 3221 and is used to drive the driving wheel 3221 to rotate. The synchronous belt 3223 is wound around the driving wheel 3221 and the driven wheel 3222. The horizontal sliding seat 321 is connected to the synchronous belt 3223. Preferably, the fixed bracket 31 is also provided with a linear guide rail 311 in the horizontal direction, and the horizontal sliding seat 321 is slidably connected to the linear guide rail 311.

[0065] Furthermore, the vertical sliding mechanism 33 includes a vertical sliding seat 331, which is slidably connected to a horizontal sliding seat 321. A screw drive mechanism 332 is also installed on the horizontal sliding seat 321. The screw drive mechanism 332 is preferably a motor. A drive screw 333 is threadedly connected to the vertical sliding seat 331. The screw drive mechanism 332 is used to drive the drive screw 333 to rotate, causing the vertical sliding seat 331 to move up and down relative to the horizontal sliding seat 321.

[0066] Furthermore, two bearing connecting seats 323 are spaced apart along the height direction on the horizontal sliding seat 321, and the vertical sliding seat 331 is located between the two bearing connecting seats 323. The two ends of the drive screw 333 are respectively connected to the bearings in the two bearing connecting seats 323. Preferably, the horizontal sliding seat 321 is also provided with two vertical guide rails 324, and the two ends of the vertical guide rails 324 extend to the upper and lower bearing seats 114 respectively.

[0067] On the one hand, the bearing in the bearing connecting seat 323 is connected to the drive screw 333. The upper and lower bearing connecting seats 323 can provide positioning for the drive screw 333, preventing the drive screw 333 from swinging during rotation and improving the stability when the drive screw 333 is linked with the vertical sliding seat 331. On the other hand, the upper and lower bearing connecting seats 323 can also provide sliding limit for the vertical sliding seat 331 in the vertical direction, controlling the movement stroke of the vertical sliding seat 331.

[0068] Furthermore, the opposing sliding mechanism 34 includes an opposing mounting plate 341, two clamping sliding seats 342, and an opposing driving mechanism 343. The opposing mounting plate 341 is connected to the vertical sliding seat, and the two clamping sliding seats 342 are slidably connected to the opposing mounting plate 341 in the horizontal direction. The opposing driving mechanism 343 is used to drive the two clamping sliding seats 342 to move closer to each other or further away from each other.

[0069] Further, the opposing drive mechanism 343 includes a lead screw drive mechanism 3431 and a drive lead screw 3432. The two ends of the drive lead screw 3432 are respectively threadedly connected to the two clamping sliding seats 342, and the thread directions of the two ends of the drive lead screw 3432 and the two clamping sliding seats 342 are opposite. In this embodiment, a lead screw nut 3433 is connected to the clamping sliding seat 342. The lead screw nut 3433 is threadedly connected to the drive lead screw 3432, and the threads of the two lead screw nuts 3433 are opposite to each other. The two clamping mechanisms 35 are respectively installed on the two clamping sliding seats 342. The lead screw drive mechanism 3431 is used to drive the drive lead screw 3432 to rotate so that the two clamping sliding seats 342 move closer to each other or further away from each other.

[0070] Because the threads of the two lead screw nuts 3433 are opposite to each other, and the threads at the connection between the drive lead screw 3432 and the two lead screw nuts 3433 are also opposite to each other, when the drive lead screw 3432 rotates, the two lead screw nuts 3433 move in opposite directions, approaching or moving away from each other. When it is necessary to insert the carbon brush into the motor housing, the two lead screw nuts 3433 are driven to move closer together, thereby causing the two clamping mechanisms 35 to carry the carbon brush closer together and insert the carbon brush into the motor housing. After installation, the two lead screw nuts 3433 are driven to move away from each other again, preparing for the next carbon brush installation. This operation method can achieve synchronous installation of two carbon brushes, saving time and effort and improving the installation efficiency of carbon brushes.

[0071] Preferably, two bearing mounting seats 344 are installed on both ends of the opposing mounting plate 341, and both ends of the drive screw 3432 are respectively connected and fixed to the bearings in the bearing mounting seats 344. The bearing mounting seats 344 provide positioning for the drive screw 3432.

[0072] Further, a swing mechanism 36 is mounted on the opposing sliding mechanism 34. The swing mechanism 36 is connected to the clamping mechanism 35, allowing the clamping mechanism 35 to swing in a vertical plane. In this embodiment, the swing mechanism 36 includes a swing fixed plate 361, a swing movable plate 362, and a swing drive mechanism 363. The swing fixed plate 361 is connected to the clamping sliding seat 342. One end of the swing movable plate 362 is rotatably connected to the swing fixed plate 361, and the other end is rotatably connected to the drive mechanism. The swing drive mechanism 363 is mounted on the swing fixed plate 361 and is used to drive the swing movable plate 362 to swing. Preferably, the swing drive mechanism 363 includes a swing drive cylinder, which is rotatably connected to the swing fixed plate 361. One end of the swing movable plate 362 is rotatably connected to the output shaft of the swing drive cylinder. In this embodiment, a fisheye joint is used at the connection between the front end of the output shaft of the swing drive cylinder and the swing movable plate 362.

[0073] With this setup, when installing the carbon brush onto the motor housing, the swing mechanism 36 can cause the carbon brush held on the clamping mechanism 35 to be inserted into the preset slot in the motor housing at an angle. Compared to horizontal insertion, angled insertion makes it easier for the carbon brush to be inserted into the slot, reducing installation difficulty and ensuring the accuracy of carbon brush installation.

[0074] Furthermore, the swing fixing plate 361 is provided with a swing limiting post 364, which is used to provide rotational limitation for the swing movable plate 362. The limiting post is located at one end of the swing movable plate 362 near the swing drive cylinder.

[0075] Furthermore, the swing fixing plate 361 is slidably connected to the clamping sliding seat 342 in the vertical direction. The clamping sliding seat 342 is provided with a sliding limit block 365, and a buffer elastic element 366 is connected between the clamping sliding seat 342 and the sliding limit block 365. The buffer elastic element 366 is preferably a spring. By providing the buffer elastic element 366, a buffering effect can be provided for the clamping mechanism 35. When the clamping mechanism 35 or the carbon brush clamped on the clamping mechanism 35 encounters an obstacle, it can have a certain range of floating space to avoid damage to the carbon brush or the clamping mechanism 35.

[0076] In this embodiment, the structures of the two swing mechanisms 36 connected to the two opposing sliding mechanisms 34 are symmetrical.

[0077] Combination Figure 10 and 11As shown, the carbon brush mounting and positioning device 4 further includes a guide seat 41, which includes two parallel guide rails 411. The two guide rails 411 have guide openings 4111 facing each other on their sides, which allow the movable end of the carbon brush to be inserted. The guide openings 4111 extend to both ends of the guide rails 411, and a movable gap is formed between the two guide rails 411 for the motor to pass through. The guide rails 411 extend along the conveying direction of the motor.

[0078] By setting two guide rails 411 with guide openings 4111 on them, when the motor passes between the two guide rails 411, the movable end of the carbon brush installed on the motor housing can be embedded into the guide opening 4111 and move along the guide opening 4111, preventing the carbon brush from detaching from the motor housing during the motor conveying process, and providing a guarantee for the subsequent insertion of the movable end of the carbon brush into the motor housing.

[0079] Furthermore, the guide opening 4111 forms a guide surface 4112 at one end of the inlet. The guide surface 4112 is provided on both the top and bottom surfaces of the inlet end of the guide opening 4111. By providing the guide surface 4112 at the end of the guide opening 4111, the end opening area is increased, making it easier for the movable end of the carbon brush to enter the guide opening 4111.

[0080] Furthermore, the guide seat 41 also includes a guide connecting seat 412, which spans over the two guide rails 411 and is connected and fixed to the two guide rails 411. Preferably, the bottom surface of the guide connecting seat 412 has two positioning slots 4121, which are correspondingly used for the two guide rails 411 to be inserted.

[0081] By setting a positioning slot 4121 on the bottom surface of the guide connector 412, the guide rail 411 can be embedded in the positioning slot 4121, which improves the connection reliability between the guide connector 412 and the guide rail 411 and ensures the stability of the distance between the two guide rails 411.

[0082] Furthermore, the carbon brush mounting and positioning device 4 also includes a positioning fixing frame 42, and the guide connecting seat 412 is slidably connected to the positioning fixing frame 42 in the horizontal direction. Preferably, the positioning fixing frame 42 is provided with a linear drive mechanism 43, which is connected to the guide connecting seat 412 and is used to drive the guide seat 41 to move linearly between two workstations. Preferably, the linear drive mechanism 43 is a drive cylinder.

[0083] In this embodiment, the guide connecting seat 412 includes a guide slider 4122, and the positioning and fixing frame 42 is provided with a fixed guide rail 44 along the horizontal direction. The guide slider 4122 is engaged with the fixed guide rail 44 and can slide along the fixed guide rail 44.

[0084] By setting the linear drive mechanism 43, the guide rail 411 can move forward synchronously with the motor as the motor moves forward, always providing positioning guidance for the carbon brush and preventing the carbon brush from coming out of the motor housing.

[0085] Furthermore, the guide connecting seat 412 includes a connecting vertical plate 4123 and a connecting horizontal plate 4124 that are perpendicularly connected to each other. The guide slider 4122 is connected to the side of the connecting vertical plate 4123 away from the connecting horizontal plate 4124. The connecting horizontal plate 4124 spans above the two guide rails 411 and is fixedly connected to the two guide rails 411. A reinforcing plate 4125 is connected between the connecting vertical plate 4123 and the connecting horizontal plate 4124. The output shaft of the drive cylinder is connected to the reinforcing plate 4125.

[0086] Combination Figures 12 to 15 As shown, further, the carbon brush movable end mounting device 5 includes a pre-positioning device 51 and a pin device 52 mounted on the positioning and fixing frame 42. The pre-positioning device 51 includes a mounting base 5113 that can move up and down relative to the positioning and fixing frame 42. A front positioning member 5101 and a rear positioning member 5102 are mounted on the mounting base 5113. At least one of the front positioning member 5101 and the rear positioning member 5102 can slide relative to the mounting base 5113 to move the front positioning member 5101 and the rear positioning member 5102 closer to or further away from each other. One of the front positioning member 5101 and the rear positioning member 5102 has an opening. The device has a positioning clamp 51021 for embedding and positioning the movable end of the carbon brush, and another positioning stop 51011 for pushing the carbon brush into the positioning clamp 51021 and sealing the positioning clamp 51021. The pin device 52 includes a pin 521 and a pin drive mechanism 522. The pin 521 is used to insert into the positioning clamp 51021 and insert the movable end of the carbon brush located in the positioning clamp 51021 into the motor housing. The pin drive mechanism 522 is used to drive the pin 521 to move horizontally and insert the pin 521 into the positioning clamp 51021.

[0087] The movable end of the carbon brush is clamped by the front positioning member 5101 and the rear positioning member 5102. Then, the pin 521 of the pin device 52 is inserted into the positioning clamp 51021, and the movable end of the carbon brush in the positioning clamp 51021 is pushed into the motor housing. This achieves complete assembly of the carbon brush and the motor housing without manual operation, realizing fully automatic production, improving production efficiency, and also improving the consistency of carbon brush installation.

[0088] In this embodiment, the rear positioning member 5102 is provided with the positioning clamp 51021, and the bottom of the front positioning member 5101 is bent toward the side close to the rear positioning member 5102 to form the positioning stop part 51011. The positioning stop part 51011 is inserted into the positioning clamp 51021 and blocks the positioning clamp 51021.

[0089] By setting a bendable positioning stop 51011 and a positioning clamp 51021 to make the fit between the front positioning part 5101 and the rear positioning part 5102 more precise, the positioning effect on the moving end of the carbon brush is improved.

[0090] In this embodiment, a lifting drive cylinder 5103 is provided on the positioning and fixing frame 42. The lifting drive cylinder 5103 is connected to the mounting base 5113 and is used to drive the mounting base 5113 to move in the vertical direction. The mounting base 5113 and the positioning and fixing frame 42 are connected by a slider rail.

[0091] Furthermore, an upper slide block 5104 and a lower slide block 5105 are respectively installed on the upper and lower surfaces of the mounting base 5113. The upper slide block 5104 and the lower slide block 5105 are slidably connected to the mounting base 5113 in the horizontal direction along the same straight line. The front positioning member 5101 is connected to the upper slide block 5104, and the rear positioning member 5102 is connected to the lower slide block 5105.

[0092] In this embodiment, the upper and lower surfaces of the mounting base 5113 are respectively connected to an upper driving cylinder 5106 and a lower driving cylinder 5107. The upper driving cylinder 5106 is connected to the upper slide block 5104 to drive the upper slide block 5104 to move horizontally, and the lower driving cylinder 5107 is connected to the lower slide block 5105 to drive the lower slide block 5105 to move. The upper slide block 5104 is connected to the mounting base 5113 through a slider rail, and the lower slide block 5105 is also connected to the mounting base 5113 through a slider rail.

[0093] Furthermore, a vertical support plate 5108 is connected to the upper slide block 5104, and the front positioning member 5101 is slidably connected to the vertical support plate 5108 in the vertical direction. A vertical sliding drive member 5109 for driving the front positioning member 5101 to move vertically is installed on the vertical support plate 5108, and the vertical sliding drive member 5109 is a cylinder.

[0094] In this embodiment, a pair of front positioning members 5101 and rear positioning members 5102 are arranged side by side, and a corresponding pair of pins 521 are provided. The two pins 521 are located on both sides of the pair of front positioning members 5101. A front connecting plate 5110 is connected to the upper end of the two front positioning plates. The front connecting plate 5110 is slidably connected to the vertical support plate 5108, and the front connecting plate 5110 and the vertical support plate 5108 are connected by a slider rail.

[0095] By setting a front connecting plate 5110 that can slide vertically, the front connecting plate 5110 drives the front positioning member 5101 to move in the vertical direction. When clamping and positioning the movable end of the carbon brush, the front positioning member 5101 can rise after separating from the rear positioning member 5102, so that the movable end of the carbon brush can be inserted into the positioning clamp 51021 in the horizontal direction. After the insertion is completed, the front positioning member 5101 moves down to reset and pushes the movable end of the carbon brush completely into the positioning clamp 51021 for positioning.

[0096] Further, the pin device 52 includes a pin fixing seat 523, and the two pin pieces 521 are slidably connected to the pin fixing seat 523 in the horizontal direction. The pin driving mechanism 522 includes a pin driving cylinder, which is connected to the two pin pieces 521 and moves the two pin pieces 521 in opposite directions to move closer to or further away from each other. Preferably, the pin positioning seat has sliding limit blocks 524 at both ends, and the two sliding limit blocks 524 are respectively used to provide sliding limit for the two pin pieces 521.

[0097] By using a pin-driven cylinder to drive two pin parts 521 to move in opposite directions, the movable ends of the two carbon brushes on the motor housing can be simultaneously inserted into the slots in the motor housing for fixing, thus improving the installation efficiency of the carbon brushes.

[0098] In this embodiment, the pin 521 includes a pin mounting plate 5211, one side of which protrudes to form a pin head 5212, which is used to be inserted into the positioning clamp 51021.

[0099] Furthermore, a rear connecting plate 5111 is connected to the lower sliding seat 5105, and two rear positioning members 5102 are connected below the rear connecting plate 5111. In this embodiment, a clamping member 5112 is also installed on the rear connecting plate 5111. The clamping member 5112 is used to press against the top surface of the motor housing after the mounting seat 5113 moves down. Preferably, the clamping member 5112 is a clamping wheel, which can rotate relative to the lower sliding seat 5105, and the clamping wheel is disposed between the two rear positioning members 5102.

[0100] By setting a clamping roller, the clamping roller can press against the upper surface of the motor. The clamping roller cooperates with the lifting device located below the motor to prevent the motor from tilting during the lifting process, thus ensuring that the pin 521 is more stable when inserting the carbon brush movable end.

[0101] The working principle of the carbon brush installation device of the present invention is as follows:

[0102] First, carbon brushes are fed via a linear conveyor track. Then, in the rotary feeding device 1, two pneumatic grippers rotate 180° back and forth, alternately clamping the carbon brushes before placing them on the rotary unloading platform 2. The rotary platform 22 on the rotary unloading platform 2 rotates to change the position of the carbon brushes. The carbon brush mounting device 3 moves the two pneumatic grippers horizontally above the rotary unloading platform 2, and then moves the pneumatic grippers down to clamp the two carbon brushes. The carbon brushes are then transferred to the top of the motor, aligned with the slots on the motor housing, and the swing mechanism 36 causes the carbon brushes to be inserted obliquely into the slots on the motor housing. At this point, only the carbon block portion of the carbon brush is inserted into the slots on the motor housing. The carbon brush mounting device 3 then resets and clamps the next pair of carbon brushes. The motor and fixture 6 are conveyed forward by a linear transfer device. When the motor moves to the carbon brush mounting and positioning device 4, the movable end of the carbon brush, i.e., the spring portion, enters the guide rail 411, ensuring that the carbon brushes do not detach from the motor housing, until the motor moves to the carbon brush movable end mounting device 5. The movable end of the carbon brush is clamped by the front positioning part 5101 and the rear positioning part 5102. Then, the pin part 521 is inserted into the positioning clamp 51021 to push the movable end of the carbon brush in the positioning clamp 51021 into the slot of the motor housing, thus completing the installation of the carbon brush.

[0103] In summary, the solution of the present invention has the following advantages:

[0104] In the carbon brush installation equipment of the present invention, the carbon brush is transferred to the rotary feeding platform 2 by the rotary feeding device 1, and the carbon brush installation device 3 clamps the carbon brush on the rotary feeding platform 2 and inserts it into the motor housing in opposite directions. The linear transfer device transfers the motor to the carbon brush movable end installation device 5. During the transfer process, the carbon brush installation positioning device 4 can position the carbon brush movable end, and the carbon brush movable end installation device 5 inserts the carbon brush movable end into the motor housing to complete the assembly of the carbon brush and the motor housing, realizing the automated installation of motor carbon brushes and greatly improving production efficiency.

[0105] The above description is only a partial embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
