Description

Technical Field

[0001] The invention relates to the field of automation, and in particular to a micro DC motor running-in device and a production method thereof. Background Art

[0002] Since the surfaces of motor components have a certain degree of roughness, and there are certain deviations in geometric shapes and assembly positions, a running-in is required after the motor is assembled to create conditions for stable wear during normal operation of the motor. Existing equipment usually sets the running-in directly on the detection equipment, so that the motor can be tested for performance immediately after the running-in. Since the time required for the running-in is often longer than the motor detection process time, the equipment has a long idle time during operation, which affects production and prolongs the production cycle. In addition, this combination of equipment is expensive and increases production costs. Using this type of equipment for running-in wastes energy. In addition, existing equipment usually performs motor loading and unloading operations manually.

At this time, the probe devices 11 located above the motor seats 10 at the loading station 14 and the unloading station 15 are both in a raised state under the action of the lifting device 16, and the motor seat 10 at the loading station 14 is empty, and the motor seat 10 at the unloading station 15 has a motor that has completed running-in.

[0072] (1) Place the motor on the motor seat 10 of the loading station 14. Specifically:

[0073] First, the barless cylinder 41 is started, and the sliding plate 43 is driven by the barless cylinder 41 to move to the material picking position. At this time, the lifting cylinder 54 is started, and the transmission shaft slides the lifting plate 20 downward along the second slide rail 45 through the second slider 46. After descending to the appropriate position, the rotating cylinder 47 is started, and the tensioning cylinder 49 and the clamping finger 48 are driven by the rotating output shaft to rotate horizontally to the angle used for material picking, and then the tensioning cylinder 49 controls the clamping finger 48 to clamp the motor.

[0074] Then, after the clamping motor is lifted, the rotating cylinder 47 is started again, driving the tensioning cylinder 49 and the clamping fingers 48 to rotate horizontally in the opposite direction to the material discharge angle, and the lifting cylinder 54 is started, and the transmission shaft slides the lifting plate 20 and the clamping assembly 21 upward along the second slide rail 45 through the second slider 46.

[0075] Next, the barless cylinder 41 is started, and the sliding plate 43 is moved to the discharge position driven by the barless cylinder 41. After it is in place, the lifting cylinder 54 is started, and the transmission shaft again slides the lifting plate 20 downward along the second slide rail 45 through the second slider 46. The tensioning cylinder 49 drives the clamping finger 48 to loosen, and the motor is placed in the motor seat 10 of the loading station 14. After completion, the lifting cylinder 54 is started again, and the lifting plate 20 and the clamping assembly 21 are slid upward along the second slide rail 45 through the second slider 46. At this time, the rotating cylinder 47 is started, and the tensioning cylinder 49 and the clamping finger 48 are driven to rotate horizontally again to the material picking angle by rotating the output shaft.

[0076] Finally, the barless cylinder 41 is started, and the sliding plate 43 is moved back to the material taking position under the drive of the barless cylinder 41, and the above steps are repeated to complete the material taking operation.

[0077] (2) Remove the motor that has completed running-in from the motor seat 10 of the unloading station 15, specifically:

[0078] First, the barless cylinder 41 is started, and the sliding plate 43 is driven by the barless cylinder 41 to move to the top of the unloading station 15. At this time, the lifting cylinder 54 is started, and the transmission shaft slides the lifting plate 20 downward along the second slide rail 45 through the second slider 46. After descending to the appropriate position, the tensioning cylinder 49 drives the clamping finger 48 to clamp the motor in the motor seat 10 of the unloading station 15. Then, the lifting cylinder 54 is started again, and the transmission shaft slides the lifting plate 20 upward along the second slide rail 45 through the second slider 46, so that the clamping finger 48 takes out the motor from the motor seat 10.

[0079] Then, after the motor is clamped, the barless cylinder 41 is started, and the sliding plate 43 is moved to the top of the discharge rail 5 under the drive of the barless cylinder 41, and the rotating cylinder 47 is started, driving the tensioning cylinder 49 and the clamping fingers 48 to rotate longitudinally 90°, so that the clamping fingers 48 flip the motor to the top of the discharge rail 5, and the tensioning cylinder 49 drives the clamping fingers 48 to loosen, placing the motor on the discharge rail 5, and the discharge rail 5 sends the motor out of the equipment.

[0080] Next, when the clamping finger 48 puts down the motor on the feeding rail, the rotating cylinder 47 starts, driving the tensioning cylinder 49 and the clamping finger 48 to rotate in the opposite direction and reset, completing the unloading and resetting, repeating the above steps to complete the unloading action.

[0081] (3) Running-in the motor in the motor seat 10 delivered to the loading station 14 in step (1), specifically:

[0082] When the motor is placed on the motor seat 10 of the aforementioned loading station 14 and the motor is taken out of the motor seat 10 of the unloading station 15, the lifting device 16 located above the loading station 14 and the unloading station 15 starts to work.

[0083] When the lifting frame 38 is in the ascending state, the probe devices 11 above the motor seats 10 of the loading station 14 and the unloading station 15 are synchronously lifted by the lifting frame 38. At this time, the rollers 26 in the probe devices 11 on the two stations are located in the slide slots 39 of the lifting frame 38. When the lifting cylinder 37 is started, the lifting frame 38 in the ascending state is pressed downward toward the top plate 8. The lifting frame 38 is driven by the lifting cylinder 37 to descend in the vertical direction. At this time, the lifting frame 38 descends. At the same time, the roller 26 inside the slide 39 is driven to descend together, and the roller 26 moves the probe 25 on the bottom fixed block 27 to the motor seat 10 below (loading station 14 and unloading station 15) through the transmission rod 24, so that the motor in the motor seat 10 at the loading station 14 contacts with the probe 25 above it, and the motor in the motor seat 10 at the unloading station 15 has been taken away, so that the motor seat 10 at this position and the probe device 11 above it are idle.

[0084] (4) The turntable mechanism 2 rotates, and the above steps are repeated to realize automated production. Specifically:

[0085] When the lifting frame 38 descends to the maximum formation, the lifting frame 38 is clamped in the clamping groove 40 of the top plate 8 and matched therewith, so that the slide groove 39 of the lifting frame 38 descends to the top plate 8. At this time, the bottom plate 6 and the middle tray 7 rotate clockwise by a running-in unit stroke, and the motor seat 10 originally located at the loading station 14 moves clockwise through the rotation of the turntable mechanism 2 and leaves the loading station 14, and the corresponding probe device 11 is disengaged from the outlet end 62 of the slide groove 39 through the roller 26, and the motor seat 10 originally located at the unloading station 15 is moved clockwise to the loading station 14 through the rotation of the turntable mechanism 2, and the motor seat 10 located at the motor seat 10 The upper probe device 11 is synchronously moved in the slide 39 to the position of the loading station 14 through the roller 26. At the same time, a motor seat 10 behind the original unloading station 15 is moved clockwise to the unloading station 15 through the rotation of the turntable mechanism 2, and its probe device 11 slides from the entrance end 61 of the slide 39 into the slide 39 through the roller 26. After it is in place, the lifting cylinder 37 is started to drive the lifting frame 38 to rise in the vertical direction, and the roller 26 is driven by the lifting frame 38 again. The roller 26 drives the probe devices 11 at the loading station 14 and the unloading station 15 to rise, waiting for the next step of putting in and taking out the motor.

[0086] Furthermore, under the cooperation of the repeated lifting and lowering movement of the lifting frame 38 and the synchronous rotation of the turntable mechanism 2, the working unit equipped with the motor at the loading station 14 is rotated out for running-in, and the working unit that completes unloading at the unloading station 15 is synchronously rotated to the loading station 14 for motor installation, and at the same time, another working unit adjacent to the unloading station 15 is synchronously moved to the unloading station 15 for motor unloading, thereby realizing assembly line type cyclic motor running-in.

Technical personnel in this industry can make some deformation and modifications under the inspiration of this technical solution.
