[0034] The working process of the unqualified workpiece collection device is as follows:

[0035] 1) When the unqualified workpiece D1 is transported to the designated position through the scrap line assembly A0, the sensor B12 detects the unqualified workpiece D1, and at this time, the output end of the lifting cylinder C3 rises axially upward, and then the top surface of the workpiece support block C6 contacts the bottom surface of the unqualified workpiece D1 and lifts the unqualified workpiece D1 to one of the magnet mounting sheet metal pairs, and then the unqualified workpiece D1 on the top surface of the workpiece support block C6 is adsorbed into the V-shaped opening of the magnet mounting sheet metal pair through the magnetic attraction of the magnet B10 on the surface of the magnet mounting sheet metal B9;

[0036] 2) When the sensor B12 detects that there is an unqualified workpiece D1 in the V-shaped opening of the magnet-mounted sheet metal pair, the output end of the cylinder C3 is lifted and lowered axially, and then the electric rotating table B6 drives the main rotating disk B8 to rotate a preset angle, which is the ratio of 360 to the total number of magnet-mounted sheet metal pairs;

[0037] 3) Repeat the above steps until there are unqualified workpieces D1 in the V-shaped openings of all magnet mounting sheet metal pairs, and then send a signal through the sensor B12 to prompt manual removal of all unqualified workpieces D1; ​​unqualified workpieces D1 can also be removed by a robot.

[0038] When the unqualified workpiece D1 is not magnetic, a magnet B10 is provided on the side surface of the magnet mounting sheet metal B9 away from the V-shaped notch where the magnet mounting sheet metal B9 is located. When the unqualified workpiece D1 is magnetic, the magnet B10 is replaced with an iron block.

[0039] like Figure 5 As shown, when the outer diameter or weight of the unqualified workpiece D1 changes, the compression amount of the spring C5 will change accordingly according to Hooke's law; the spring C5 ensures that when the weight of the unqualified workpiece D1 increases, the lifting cylinder C3 lifts the unqualified workpiece D1 to the V-shaped opening of the magnet mounting sheet metal pair, and there is a gap between the unqualified workpiece D1 and the magnet mounting sheet metal B9; when the weight of the unqualified workpiece D1 decreases, the lifting cylinder C3 lifts the unqualified workpiece D1 to the V-shaped opening of the magnet mounting sheet metal pair, and the magnetic force between the magnet B10 and the unqualified workpiece D1 can adsorb the unqualified workpiece D1 and fit it with the magnet mounting sheet metal B9; this ensures that there is no need to replace or adjust the tooling when the workpiece changes.
