The channel gradually narrows at the outlet so that the outlet of the channel matches the outer diameter of the bearing 24. This arrangement allows workers to place more bearings 24 on the conveyor 2 at a time, while ensuring that the bearings 24 exit the channel one by one.

[0021] The second guide plate 4 is connected to the frame of the conveyor 2 through multiple first brackets 17, and the second guide plate 4 is always kept fixed.

The distance between the two push rods 21 close to the conveyor 2 is greater than the diameter of the bearing 24, and the distance between the other two push rods 21 is less than the diameter of the bearing 24. The rotary cylinder 18 adopts MSZB10 type.

[0025] The detection table 9 is provided with a first through hole 22 and a second through hole 23.

[0027] Working principle: workers place a plurality of bearings 24 on the conveyor 2, the bearings 24 move in the channel and are output one by one until one of the bearings contacts the baffle 5, the resistance of the baffle 5 makes the bearings 24 on the conveyor 2 gradually stop moving.

[0028] The controller 1 makes the telescopic cylinder 6 rapidly extend and then retract through the first electromagnetic valve 7, so that the bearing is pushed out to the backing plate 11, Figure 1The two poking rods 21 close to the right side avoid the bearings from flying out of the base plate 11, and the subsequent bearings will be moved to the baffle 5 under the action of the conveyor 2. The controller determines the weight of the bearings according to the signal on the pressure sensor 12, and when the weight of the bearings on the base plate 11 is the weight of the bearings without missing balls, the controller 1 makes the rotary cylinder 18 rotate clockwise and then return to the original position through the second electromagnetic valve 19, in the process, the bearings are driven to the first through hole 22 by the poking rod 21, and the bearings fall from the first through hole 22; when the weight of the bearings on the base plate 11 is less than the weight of the bearings without missing balls, the controller 1 makes the rotary cylinder 18 rotate counterclockwise and then return to the original position through the second electromagnetic valve 19, in the process, the bearings are driven to the second through hole 23 by the poking rod 21, and the bearings fall from the second through hole 23.
