[0002] With the substantial increase in the usage rate of automobiles in China, the demand for automotive air-conditioning compressors, as a major component of automobiles, has also increased significantly. An automotive air-conditioning compressor is an important device for cooling the automobile cabin, and is usually composed of a cylinder block, a cylinder head, a crankshaft, a piston, etc. Among them, the assembly of the cylinder head cover is a key link affecting the overall performance and quality of the compressor. At present, most of the assembly of the cylinder head cover on the air-conditioning compressor is manual or semi-automatic assembly, with low efficiency and poor accuracy. Due to the high assembly accuracy requirements for the cover, the automation assembly is difficult.

[0003] In recent years, in response to this problem, some manufacturers have adopted an automated cover assembly device, which uses an assembly line operation. The equipment used is numerous, occupies a large area, and this automated assembly device has a high cost, and the installation and maintenance are also relatively complex, which limits its application in the compressor production line.

Cooperating with the cover body transfer mechanism 3 arranged between the workbench 1 and the cover body conveying mechanism 2, the entire equipment occupies a small area and has a strong process compactness. Only through the first manipulator 32 and the second manipulator 33 on the cover body transfer mechanism 3 can the three assembly steps of the cover body be realized, reducing the production line steps and the production line investment.

[0055] Please refer to Figures 2 - 3 In this embodiment, the cover body conveying mechanism 2 includes a feeding conveyor belt 21 and a discharging conveyor belt 22 arranged parallel and symmetrically on both sides of the workbench 1, and a transfer conveyor belt 23 arranged perpendicular to the feeding conveyor belt 21 and the discharging conveyor belt 22.

A screw inspection tray 434 and a screw waiting tray 435 are provided on one side of the screw receiving tray 433. The screw tightening mechanism 45 includes a first magnetic suction head 451 and a rotating motor 452 that drives the first magnetic suction head 451 to rotate.

[0064] Specifically, the first clamping jaw 432 is used to clamp the screws from the screw receiving tray 433 to the screw inspection tray 434, and after inspection and no problems, then clamp them to the screw waiting tray 435. The screw tightening mechanism 45 moves to above the screw waiting tray 435 through a three-axis moving mechanism, sucks the screws through the first magnetic suction head 451, moves above the first fixed disk 42 fixing the cover body, the screw tightening mechanism 45 presses down and starts the rotating motor 452 to complete the screw assembly. Then the first fixed disk 42 resets. During the reset process of the first fixed disk 42, the first clamping jaw 432 continuously clamps and transfers the screws for inspection, waiting for the assembly of the next cover body, greatly saving the waiting time for screw assembly.

[0065] Please refer to Figures 8 - 9 , further, the pin assembly station 5 includes a pin feeding vibrating disk 51 fixed on the workbench 1, a second fixed disk 52, and a second reciprocating module 53 that drives the second fixed disk 52 to reciprocate.
