Technical Field

[0001] This utility model relates to the field of automated carbon brush processing equipment, and in particular to a brush box feeding mechanism. Background Technology

[0002] Patent application CN201810580200.7 discloses a carbon brush and a carbon brush cartridge assembly, including a carbon brush cartridge composed of symmetrically installed carbon brush cartridge bodies. The cartridge bodies are made of polyoxymethylene. A long groove is machined on the inner side of the support body, and a deformation groove is machined on the outer side. The deformation groove is located below the long groove, and a guide surface is machined on the upper part of the long groove. The carbon brush is formed by a compression spring connecting the brush body and a carbon brush connecting piece. The bottom of the brush body is curved, and the curved surface matches the outer circular shape of the commutator. The middle part of the carbon brush connecting piece is a narrow section. The size of the nozzle matches the long slot, and the carbon brush connector is fixedly connected to the external wiring. The brush body, compression spring, and carbon brush connector are made of conductive metal. The carbon brush body is inserted into the carbon brush box, and the carbon brush connector is pressed. Through the elastic deformation of the upper part of the carbon brush box, the carbon brush can be easily installed in the carbon brush box. In actual processing and assembly, it is often necessary to manually place the brush box into the installation fixture before proceeding with the subsequent carbon brush insertion process. In some cases, the carbon brush and brush box are assembled manually, resulting in low processing efficiency. Utility Model Content

[0031] Reference Figures 1 to 3 The brush box feeding mechanism of this utility model embodiment includes a movable frame 100, a first slider 200, a second slider 300, and a picking claw 400. The first slider 200 and the movable frame 100 are slidably connected; the second slider 300 and the movable frame 100 are slidably connected, and the movement direction of the second slider 300 is the same as that of the first slider 200; the picking claw 400 is used to pick up and put down the brush box, and the picking claw 400 is movably and vertically mounted on the second slider 300; wherein, the first slider 200 is provided with a driving mechanism, and the driving mechanism is connected to the second slider 300 to drive the second slider 300 away from or near the first slider 200, and the picking claw 400 is located at the end of the second slider 300 away from the driving mechanism.

[0032] In practical use, the movable frame 100 is fixed on the ground or a fixed frame. The first slider 200 and the second slider 300 can reciprocate along the same straight line on the movable frame 100. The picking claw 400 is installed on the second slider 300. The brush box located below is taken out by lifting and lowering, and the brush box is placed in the mounting fixture 700 located above. The mounting fixture 700 is used to clamp the brush box for subsequent processing. The first slider 200 moves to move the second slider 300 and the picking claw 400, while the second slider 300 moves to move the picking claw 400 horizontally. The two-stage drive method can improve the stability and reliability of the entire movement process.

[0033] In summary, by using the picking claw 400, which can move horizontally and vertically, to pick up and place the brush box, the brush box can be placed into the processing and installation fixture 700 without manual intervention, which greatly improves processing efficiency.

[0034] In some embodiments, the picking claw 400 includes a lifting block 410 and a finger cylinder 420, the lifting block 410 and the second slider 300 being slidably connected; the finger cylinder 420 is fixed on the lifting block 410, and the driving end of the finger cylinder 420 is fixedly connected to two grippers 430, the two grippers 430 being disposed at the end facing away from the first slider 200; wherein, the two grippers 430 can open or close in a vertical plane. The two drive ends of the finger cylinder 420 can be opened to both sides. Specifically, the two grippers 430 on the finger cylinder 420 extend into the brush box and are driven by the drive ends to open the two grippers 430 to both sides of the finger cylinder 420. The grippers 430 hold the brush box tightly from the inside of the brush box and remove the brush box. Then, the lifting mechanism aligns the picking claw 400 with the mounting fixture 700. The second slider 300 places the brush box on the grippers 430 into the mounting fixture 700. Finally, the grippers 430 release the brush box under the drive of the finger cylinder 420 and are removed from the brush box under the action of the second slider 300 and the first slider 200.

[0035] In some embodiments, in order to constrain the stability of the lifting claw 400's vertical movement, the second slider 300 is provided with a vertical second slide rail 310, the lifting block 410 and the second slide rail 310 are slidably connected, and the second slider 300 is fixedly connected to a lifting cylinder 320, which is fixedly connected to the lifting block 410 to drive the lifting block 410 to move up and down.

[0036] Furthermore, the driving mechanism is a second cylinder 210, and the driving end of the second cylinder 210 is fixedly connected to the end of the second slider 300 away from the picking claw 400. This enables the second cylinder 210 to drive the second slider 300 to slide back and forth.

[0037] It should be mentioned that, in order to constrain the total stroke of the second slider 300 and prevent it from being on the picking claw 400, a stop plate 110 is provided at the end of the moving frame 100 near the second slider 300. The stop plate 110 can abut against the second slider 300 to constrain the position of the second slider 300. Furthermore, in order to adapt to different feed distances, a mounting groove is provided on the side of the stop plate 110 facing the second slider 300, and a stop block 120 is detachably installed in the mounting groove. After installation, according to the actual feed distance required by the picking claw 400, the feed distance of the second slider 300 can be shortened by installing the stop block 120 in the mounting groove to meet the feeding requirements of the picking claw 400.

[0038] In some embodiments, a first slide rail is provided on one side of the movable frame 100, and a portion of the first slider 200 and the second slider 300 are slidably connected to the first slide rail. It should be emphasized that a first cylinder 130 is fixedly connected to one end of the movable frame 100 near the first slider 200. The driving end of the first cylinder 130 is fixedly connected to the end of the movable frame 100, and one side of the cylinder body of the first cylinder 130 is fixedly connected to the first slider 200. Accordingly, a portion of the first slider 200 extends beyond the end of the movable frame 100 and is connected to the first cylinder 130, driven by the first cylinder 130 to reciprocate; the other portion is slidably connected to the first slide rail, achieving a slidable connection with the movable frame 100. The second slider 300 is connected to the first slide rail, so that the movement paths of the second slider 300 and the first slider 200 are consistent.

[0039] In some embodiments, the brush box feeding mechanism further includes a conveying pipe 500, which is inclined downward from the inlet end toward the outlet end. The outlet end of the conveying pipe 500 is provided with a notch 510 for the picking claw 400 to extend into. Multiple brush boxes are conveyed side by side to the mounting fixture 700 via the conveying pipe 500, forming an upper and lower positional relationship with the mounting fixture 700. The lifting picking claw 400 extends into the notch 510 and removes the brush boxes from the conveying pipe 500. Furthermore, in order to convey the brush boxes within the conveying pipe 500, a vibrating feeder 600 is connected to the inlet end of the conveying pipe 500.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
