[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0038] like Figure 1 As shown, the present invention provides a carbon brush installation device, including a rotary feeding device 1, a rotary discharge 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 brush to 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, and insert the head of the carbon brush into the motor housing; the carbon brush installation positioning device 4 is arranged between the carbon brush installation device 3 and the carbon brush movable end installation device 5, and is used for the movable end of the carbon brush to be embedded and provide a sliding guide for the linear transfer process of the motor; the carbon brush movable end installation device 5 is used to clamp and position the movable end of the carbon brush and then insert the movable end of the carbon brush into the motor housing; the linear transfer device is used to perform linear transfer on the motor.
[0039] The carbon brush is transferred to the rotating discharge platform 2 through the rotating feeding device 1, the carbon brush installation device 3 clamps the carbon brush on the rotating discharge platform 2 and then inserts it into the motor housing oppositely, and 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, thereby realizing the automated installation of the motor carbon brush and greatly improving the production efficiency.
[0040] In this embodiment, the linear transfer device adopts a conveyor belt, the motor is placed on the fixture 6, and the fixture 6 is transported forward by the conveyor belt.
[0041] In this embodiment, the carbon brushes are fed through a linear conveying track, and the fed carbon brushes are sequentially transferred to the top of the rotating discharge platform 2 through the rotating feeding device 1 .
[0042] Combination Figure 2 and 3 As shown, further, the rotary feeding device 1 includes a rotary material picking bracket 11 and a material picking mechanism 12, the material picking mechanism 12 is installed on the rotary material picking bracket 11 and can move vertically relative to the rotary material picking bracket 11, the material picking 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 can be vertically slidably connected to the rotary material picking bracket 11, the rotating frame 122 can be rotatably connected to the vertical slide 121, the primary rotary drive element 123 is used to drive the rotating frame 122 to rotate, and a pair of clamping elements 124 are installed on the rotating frame 122, which are symmetrically distributed with respect to its rotation center, and the clamping element 124 is used to clamp the carbon brush.
[0043] The rotating frame 122 is driven to rotate by the primary rotating driving element 123, and 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 brushes and transfer them to symmetrical positions, thereby realizing continuous transfer of the carbon brushes. The carbon brush transfer efficiency is high, and the installation efficiency of the carbon brushes is improved.
[0044] Furthermore, the rotary material-grabbing support 11 is provided with a main rotary drive element 111 and a lifting screw 112, the lifting screw 112 passes through the vertical slide 121 and is threadedly connected to the vertical slide 121, and the main rotary drive element 111 is used to drive the lifting screw 112 to rotate. Preferably, the rotary material-grabbing support 11 is provided with at least two parallel vertical guide rails 113, the vertical slide 121 is engaged with the vertical guide rail 113 and can slide along the vertical guide rail 113. In this embodiment, the primary rotary drive element 123 and the main rotary drive element 111 are both motors, and the lifting screw 112 is connected to the output shaft of the main rotary drive element 111 and rotates with the output shaft.
[0045] The lifting screw 112 is driven to rotate by a motor. With the help of the threaded connection between the lifting screw 112 and the vertical slide 121, when the lifting screw 112 rotates, the vertical slide 121 moves up and down along the vertical guide rail 113, and the vertical slide 121 drives the rotating frame 122 to move up and down. Since the lifting screw 112 and the vertical slide 121 are in a threaded matching relationship, the two can achieve self-locking in the vertical direction, which can prevent the vertical slide 121 from being affected by gravity in the vertical direction and automatically displacing, affecting the accuracy of the clamping element 124 when clamping the carbon brush. In addition, by adopting the threaded transmission method, the structural transmission is more stable and the transmission accuracy is higher, which further improves the accuracy of the clamping element 124 in clamping the carbon brush.
[0046] Furthermore, two bearing seats 114 are arranged at intervals along the height direction of the rotating material taking support 11, the vertical slide seat 121 is located between the two bearing seats 114, and the two ends of the lifting screw rod 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.
[0047] On the one hand, the bearing in the bearing seat 114 is connected to the lifting screw 112. The upper and lower bearing seats 114 can provide positioning for the lifting screw 112 to prevent the lifting screw 112 from swinging during rotation, thereby improving the stability of the lifting screw 112 when it is linked to the vertical slide 121; on the other hand, the upper and lower bearing seats 114 can also provide sliding limits for the vertical slide 121 in the vertical direction to control the moving stroke of the vertical slide 121.
[0048] Furthermore, a lifting position sensing sheet 115 is installed on the vertical slide 121, and a lifting position sensing element 116 is installed on the rotating material picking bracket 11, and the lifting position sensing element 116 is used to sense and identify the lifting position sensing sheet 115. In this embodiment, the lifting position sensing sheet 115 is an L-shaped sheet, and the lifting position sensing element 116 is preferably a photoelectric switch. Using the principle of light induction, when the lifting position sensing sheet 115 reaches the photoelectric switch, an electrical signal can be fed back to the control center to control the lifting and lowering adjustment of the vertical slide 121 in real time, ensure that the clamping element 124 reaches the specified position, and improve the accuracy of the clamping element 124 when clamping the carbon brush.
[0049] Furthermore, the rotating material picking bracket 11 is provided with an adjustment track 117 along its height direction, and the lifting position sensing element 116 is installed on the adjustment track 117 and can be moved and adjusted relative to the adjustment track 117. Preferably, the lifting position sensing element 116 is fixed to the adjustment track 117 by screws, and the lifting position sensing element 116 can be fixed at a specified height position of the adjustment track 117 as needed.
[0050] By adjusting the height position 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 stop position of the clamping element 124 to meet the clamping requirements of different products, which is convenient to adjust and has higher applicability.
[0051] Furthermore, a pair of secondary rotation drive elements 125 are installed on the rotating frame 122. The secondary rotation drive elements 125 are arranged one-to-one 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 rotation drive elements 125 are motors.
[0052] Since the head of the carbon brush is a carbon block and the movable end of the tail is a spring and a metal sheet, when the carbon brush is transferred to the rotating feeding mechanism, the head faces forward and the spring and the metal sheet are located at the rear. After the clamping element 124 clamps the carbon brush, the primary rotating drive element 123 drives the rotating frame 122 to rotate. At this time, the direction of the carbon brush changes after rotating 180°. By setting a secondary rotating drive element 125, the clamping element 124 is driven to rotate 180°, so that the direction of the carbon brush is restored to its initial state, which is convenient for the subsequent installation of the carbon brush.
[0053] Furthermore, the driving shaft of the secondary rotating driving element 125 is connected to the clamping element 124 and is used to drive the clamping element 124 to rotate. A secondary sensing sheet 126 is installed on the circumferential side wall of the driving shaft of the secondary rotating driving element 125.

The secondary sensing element 127 is preferably a photoelectric switch, and the secondary sensing sheet 126 is an L-shaped thin sheet.
[0054] The secondary sensor sheet 126 is identified by means of a photoelectric switch to ensure that the clamping element 124 rotates to a preset angle, thereby ensuring that the clamping element 124 can accurately clamp and transfer the carbon brush, thereby achieving precise control over the transfer of the carbon brush.
[0055] Furthermore, the driving shaft of the primary rotating driving element 123 is connected to the rotating frame 122 and is used to drive the rotating frame 122 to rotate. A primary sensing sheet 128 is installed on the circumferential side wall of the driving shaft of the primary rotating driving element 123. 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 sheet 128. The primary sensing element 129 is a photoelectric switch, and the primary sensing sheet 128 is an L-shaped sheet.
[0056] The primary sensing sheet 128 is identified by means of a photoelectric switch, and the rotation angle of the rotating frame 122 is precisely controlled, thereby ensuring the accuracy of the rotation angle of the clamping element 124 .
[0057] In this embodiment, the clamping element 124 is a pneumatic clamp, which controls the opening and closing of the clamping piece by pneumatic means to clamp the carbon brush, and can realize picking and placing with high transfer efficiency.

The rotation sensing element 25 is preferably a photoelectric switch, and the rotation sensing sheet 24 is an L-shaped sheet. By sensing the rotation sensing sheet 24 with the photoelectric switch, the rotation angle of the rotating platform 22 can be accurately controlled to ensure that the carbon brush can be accurately placed in the placement slot 221.
[0060] Furthermore, the angle between the rotating feeding platform and the carbon brush installation device 3 relative to the rotating unloading platform 2 is 90°. With this arrangement, when transferring the carbon brushes, the carbon brushes placed by the rotating feeding platform and the carbon brush installation device 3 clamping the carbon brushes do not interfere with each other, and the carbon brush installation device 3 can clamp the two carbon brushes at the same time, thereby achieving synchronous installation of the two carbon brushes and improving installation efficiency.
[0061] Combination Figures 5 to 9 As shown, further, the carbon brush installation device 3 includes a fixed bracket 31, a horizontal sliding mechanism 32, a vertical sliding mechanism 33, an opposite 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 respectively used to clamp the carbon brush; the opposite sliding mechanism 34 is installed 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 brush into the motor housing. In this embodiment, the clamping mechanism 35 is preferably a pneumatic clamp.
[0062] With the help of the horizontal sliding mechanism 32, the position of the clamping mechanism 35 can be changed in the horizontal direction to transfer the carbon brush horizontally. With the help of the vertical sliding mechanism 33, the vertical position of the clamping mechanism 35 can be changed to take and place the carbon brush. With the help of the opposite sliding mechanism 34, the two clamping mechanisms 35 can be moved in opposite directions, so that the carbon brushes can be respectively inserted into the slots on both sides of the motor housing to achieve the installation of the carbon brushes.

The driving 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, a linear guide rail 311 is also provided on the fixed bracket 31 in the horizontal direction, and the horizontal sliding seat 321 is slidably connected to the linear guide rail 311.
[0064] Furthermore, the vertical sliding mechanism 33 includes a vertical sliding seat 331, which is slidably connected to the horizontal sliding seat 321. A screw driving mechanism 332 is also installed on the horizontal sliding seat 321. The screw driving mechanism 332 is preferably a motor. A driving screw 333 is threadedly connected to the vertical sliding seat 331. The screw driving mechanism 332 is used to drive the driving screw 333 to rotate so that the vertical sliding seat 331 can move up and down relative to the horizontal sliding seat 321.
[0065] Furthermore, two bearing connection seats 323 are arranged at intervals on the horizontal sliding seat 321 along the height direction thereof, the vertical sliding seat 331 is located between the two bearing connection seats 323, and the two ends of the driving screw 333 are respectively connected to the bearings in the two bearing connection seats 323. Preferably, the horizontal sliding seat 321 is further provided with two vertical guide rails 324, and the two ends of the vertical guide rails 324 respectively extend to the upper and lower bearing seats 114.
[0066] On the one hand, the bearing in the bearing connecting seat 323 is connected to the driving screw 333. The upper and lower bearing connecting seats 323 can provide positioning for the driving screw 333 to prevent the driving screw 333 from swinging during rotation, thereby improving the stability of the driving screw 333 when linked with the vertical sliding seat 331; on the other hand, the upper and lower bearing connecting seats 323 can also provide sliding limits for the vertical sliding seat 331 in the vertical direction to control the moving stroke of the vertical sliding seat 331.

[0069] Since the threads of the two screw nuts 3433 are opposite to each other, the threads of the connection between the drive screw 3432 and the two screw nuts 3433 are also opposite to each other, so that when the drive screw 3432 rotates, the two screw nuts 3433 move in opposite directions to get closer to each other or farther away from each other. When the carbon brush needs to be inserted into the motor housing, the two screw nuts 3433 are driven closer to each other, so that the two clamping mechanisms 35 carry the carbon brushes closer to each other, and the carbon brushes are inserted into the motor housing. After the installation is completed, the two screw nuts 3433 are driven away from each other to prepare for the next installation of the carbon brush.

[0072] Through such an arrangement, when the carbon brush is installed on the motor housing, the carbon brush clamped on the clamping mechanism 35 can be inserted into the preset slot hole of the motor housing at an inclined angle through the swing mechanism 36. Compared with horizontal insertion, oblique insertion can make the carbon brush easier to insert into the slot hole, reduce the difficulty of installation, and ensure the accuracy of carbon brush installation.
