[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an automatic carbon brush clamping and screw-locking mechanism includes a machine base 1, a belt conveyor 2, a tooling plate 3, a stator housing transport device 4, a carbon brush transport device 5, and a carbon brush clamping and screw-locking device 6. The tooling plate 3 is equipped with a carbon brush clamping and releasing mechanism 7 and a stator housing positioning mold 8. The belt conveyor 2 is positioned on the machine base 1 in a left-right direction, and the tooling plate 3 is placed side-by-side in the middle of the conveyor belt 21 of the belt conveyor 2. The carbon brush clamping and releasing mechanism 7 is located on both sides of the tooling plate 3, at the front and rear sides of the conveyor belt 21, and is capable of clamping and releasing two carbon brushes on the tooling plate 3. The carbon brush 9 at one end is fixed; the stator housing transport device 4 is located in the upper right part of the middle of the machine base 1, and is located near the middle of the conveyor belt 21 of the belt conveyor device 2, and can move the stator housing 10 onto the tooling plate 3; the carbon brush transport device 5 is located in the upper left part of the middle of the machine base 1, and can transport the carbon brush 9 to the carbon brush clamping and releasing mechanism 7 at both ends of the tooling plate 3; the carbon brush locking screw device 6 is located in the upper right side of the machine base 1, and can insert the carbon brush into the stator housing 10, and at the same time insert the screw into the screw hole of the carbon brush 9 to fix the carbon brush 9 onto the stator housing 10.

[0028] like Figure 5 As shown, the carbon brush clamping and releasing mechanism 7 includes a slide rail 71, a slide base 72, a guide post 73, a spring 74, a carbon brush gripper 75, and a follower 76. The slide rail 71 is fixed in the middle of the tooling plate 3. The slide base 72 is slidably connected to the slide rail 71. The two ends of the guide post 73 are respectively connected to the two sides of the slide base 72. The carbon brush gripper 75 and the spring 74 are slidably sleeved on the guide post 73, and the spring 74 is located between the carbon brush gripper 75 and the side of the slide base 72. The follower 76 is connected to the outside of the carbon brush gripper 75.

[0029] like Figure 6 As shown, the conveyor belt 21 of the belt conveyor device 2 is equipped with a carbon brush gripper opening cylinder 22 and a tooling plate positioning cylinder 23 on both the front and rear sides. The driving end of the carbon brush gripper opening cylinder 22 faces between the two followers 76 on the tooling plate 3, and the driving end of the tooling plate positioning cylinder 23 faces the tooling plate 3.

[0030] like Figure 7As shown, the carbon brush screw-locking device 6 includes a stand 61, a servo module Z-axis cylinder 62, a servo module Y-axis cylinder 63, a stator housing clamping cylinder 64, and a carbon brush screw-locking motor 65. The stand 61 is erected above the conveyor belt 21 on the right side of the machine base 1. The servo module Z-axis cylinder 62 and servo module Y-axis cylinder 63 are installed at both ends of the upper part of the stand 61. The carbon brush screw-locking motor 65 is installed on both sides of the lower part of the stand 61, and the drive end of the carbon brush screw-locking motor 65 is connected to a screwdriver bit 651. The stator housing clamping cylinder 64 is erected in the middle of the stand 61, and the drive end of the stator housing clamping cylinder 64 faces the stator housing positioning mold 8 on the tooling plate 3 below, so that the stator housing 10 can be pressed and fixed after the drive end of the stator housing clamping cylinder 64 extends downward.

[0031] like Figure 8 As shown, a carbon brush feeding device 11 is also provided on the front side of the machine base 1. The carbon brush feeding device 11 includes a tray 111, a tray Z-axis servo drive mechanism 112, and a tray Y-axis servo drive mechanism 113. The tray 111 is positioned above the tray Z-axis servo drive mechanism 112 and can be driven to move the tray 111 up and down. The tray 111 is positioned to the left of the tray Y-axis servo drive mechanism 113 and can be driven to move the tray 111 left and right. Carbon brushes 9 are placed on the tray 111, thereby driving the carbon brushes 9 to the side of the carbon brush transport device 5 to facilitate the subsequent transport of the carbon brushes 9 by the carbon brush transport device 5.

[0032] The operating steps of this automatic carbon brush screw-locking mechanism are as follows:

[0033] First, the carbon brushes 9 are placed one by one on the tray 111 by manual labor. Then, the tray Z-axis servo drive mechanism 112 and the tray Y-axis servo drive mechanism 113 put the tray 111 into the equipment. The carbon brushes 9 are automatically picked up by the handling cylinder and gripper of the carbon brush handling device 5 and placed in the tooling plate 3.

[0034] Next, the carbon brush 9 is fixed by the carbon brush clamping and releasing mechanism 7 on the tooling plate 3. Since the carbon brush clamping claw 75 has extending springs 74 on both sides, the carbon brush clamping claw 75 is in a closed state under normal conditions. When the carbon brush conveying device 5 is ready to release the material, the carbon brush clamping claw opening cylinder 22 is activated, causing the drive head to insert between the two follower 76, which compresses the spring 74 and opens the carbon brush clamping claw 75. The conveying cylinder of the carbon brush conveying device 5 descends, so that the carbon brush 9 is in the middle of the two carbon brush clamping claws 75. Then the carbon brush clamping claw opening cylinder 22 retracts, and the two carbon brush clamping claws 75 close and clamp the carbon brush 9. The tooling plate 3 moves to the next station through the conveyor belt 21 of the belt conveyor device 2.

[0035] Then, the stator housing 10 is placed by the stator housing transport device 4 into the stator housing positioning mold 8 on the tooling plate 3 where the carbon brushes 9 are placed, and then moved to the next station. Next, the screwdriver bit 651 is fed by the screw feeder 12, and the carbon brush screw motor 65 controls the torque to lock the carbon brushes 9 and the stator housing 10 with screws. During this process, when the conveyor belt 21 of the belt conveyor device 2 carries the tooling plate 3 to the position, the drive end of the servo module Z-axis cylinder 62 drives the carbon brush screw motor 65 and the screwdriver bit 651 to descend, and the stator housing clamping cylinder 64 drives the rod downward to press and fix the stator housing 10 in the stator housing positioning mold 8. At this time, the screwdriver bit 651 is directly facing the screw hole on the carbon brushes 9. Finally, the Y-axis cylinder 63 of the servo module drives the carbon brush insertion and screw locking device 6 to move forward, inserting the carbon brush 9 into the stator housing 10. As the carbon brush 9 is in place, the screw is locked onto the stator housing 10.

[0036] In this example, the present invention includes a belt conveyor 2, a tooling plate 3, a stator housing transport device 4, a carbon brush transport device 5, and a carbon brush locking screw device 6. The tooling plate 3 is equipped with a carbon brush clamping and releasing mechanism 7 and a stator housing positioning mold 8. The belt conveyor 2 is positioned on the machine base 1 along the left-right direction, and the tooling plate 3 is placed side-by-side in the middle of the conveyor belt 21 of the belt conveyor 2. The carbon brush clamping and releasing mechanism 7 is located on both sides of the tooling plate 3, at the front and rear sides of the conveyor belt 21, and can hold the carbon brushes at both ends of the tooling plate 3. 9. The stator housing transport device 4 is located in the upper right part of the middle of the machine base 1, near the feed end of the conveyor belt 21 of the belt conveyor device 2, and is used to move the stator housing 10 onto the tooling plate 3; the carbon brush transport device 5 is located in the upper left part of the middle of the machine base 1, and is used to transport the carbon brush 9 to the carbon brush clamping and releasing mechanisms 7 at both ends of the tooling plate 3; the carbon brush insertion and screw locking device 6 is located on the upper right side of the machine base 1, and can insert the carbon brush 9 into the stator housing 10, and simultaneously insert the screw into the screw hole of the carbon brush 9 to fix the carbon brush 9 onto the stator housing 10. This realizes the automation of inserting the carbon brush 9 into the stator housing 10 and tightening the screw, with stable and fast operation. It not only greatly improves the installation efficiency and reduces the processing cost, but also avoids individual differences caused by manual operation, improves product quality, reduces the labor intensity of workers, and alleviates the operating burden of small and micro brushed motor manufacturing enterprises. Thus, it achieves the goal of novel design, reasonable structure, and good application effect.

[0037] The above description is only a preferred embodiment of the automatic carbon brush mounting and screw locking mechanism of this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
