The double-head placement machine according to claim 1, characterized in that: Active rotating arc blocks (41) are provided at both ends of the sixth shaft (40), and each rolling valve (35) is provided with a driven rotating arc block (351) capable of movably cooperating with the active rotating arc block.

4. The double-head placement machine as claimed in claim 3, characterized in that: The included angle of the driven rotating arc block (351) is less than 180 degrees, and the included angle of the active rotating arc block (41) is less than 180 degrees. The active rotating arc block has an initial position, a second position for placing the rolling valve (35) in a vacuum position, and a third position for placing the rolling valve in a blowing position, wherein the initial position is the working origin position of the sixth axis (40). When the active rotating arc block (41) is in the initial position, the mounting machine head body can rotate arbitrarily, and the active rotating arc block will never have any obstruction or interference with any driven rotating arc block (351), that is, after the forward driving rolling valve (35) and before the reverse driving rolling valve, the active rotating arc block (41) is adjacent to one side wall of the driven rotating arc block; after the reverse driving rolling valve and before the forward driving rolling valve, the active rotating arc block is adjacent to the other side wall of the driven rotating arc block.

5. The double-head placement machine according to claim 2, characterized in that: The fifth rotating shaft is hollow and communicates with the vacuum pipe (53). The chip mounter head body (31) is provided with a vacuum through-structure communicated with the vacuum pipe. The side wall (22) of the rotating frame is provided with an air blowing port (221). The chip mounter head body is provided with the air blowing through-structure. The rolling valve (35) is provided with a vacuum air passage and an air blowing passage. When the rolling valve is in the vacuum position, the vacuum air passage and the vacuum through-structure are communicated with the suction nozzle (33). When the rolling valve is in the air blowing position, the air blowing passage and the air blowing through-structure are communicated with the suction nozzle, and the air blowing port (221) can blow air toward the air blowing through-structure.

6. The double-head placement machine according to claim 1, characterized in that: A left half shaft (51) and a right half shaft (52), one end of each half shaft is provided with a bevel gear set, each bevel gear set is matched with a motor and a transmission shaft, the motor transmits power to the bevel gear set through the transmission shaft, the transmission shaft includes a spline sleeve section and a spline shaft section matched together, the motor is arranged on a rotating disk (60), and the rotating disk is provided with a spline nut (61) matched with the fourth rotating shaft (10).
