Background In the new energy industry, especially in battery assembly production, the upper end cover and the lower end cover of the cylindrical battery are round end pieces, and the diameters of the round end pieces are required to be consistent in the production process. In the related art, in order to ensure the stability of the tray supporting the circular end piece, a placement hole for limiting the circular end piece is generally formed on the tray. The inner diameter of the placement hole is typically slightly larger than the diameter of the circular end piece (clearance about 0.5-1 mm). When the circular end piece is placed in the placement hole, the circular end piece is easily abutted against the inner wall of the placement hole to incline. When the manipulator is used for carrying the round end piece, the negative pressure adsorption surface of the manipulator is not fully contacted with the surface of the round end piece, and slipping occurs in the carrying process. When the manipulator conveys the round end piece in an inclined state to the detection probe, the round end piece in the inclined state cannot be accurately placed into the detection station by the manipulator, so that the error rate is increased during detection, and the technical problem of misjudgment is caused.
