Preferably, the support is connected with the SCARA robot through a tool flange, and the support is in a cross shape. The tool flange enables the connection between the tool flange and the tool flange to be more stable, and the action is softer during operation. The cross-shaped support can just assemble 4 parts of the robot tool, so that the balance of the robot tool can be kept, and the stability of the equipment during operation is ensured.

The utility model has the advantages that: by robot control, high accuracy manipulator automatic assembly stator rotor, vision system shoots in real time to realize automatic assembly and detect, great improvement production efficiency, guaranteed the assembly precision, the cost of using manpower sparingly.

Detailed Description

The following embodiments are specifically described with reference to fig. 1 to 6:

as shown in fig. 6, a vacuum pump 12 is disposed on the tool tray 13, and the stator 7 and the rotor 10 are assembled at the upper part of the vacuum pump, so that the utility model provides a how to assemble the stator and the rotor on the vacuum pump.

As shown in FIG. 1, the utility model discloses regard as main control unit by SCARA robot 1, coordinate each part of robot frock 2 and realize the assembly.

As shown in fig. 2 and 3, the robot tooling 2 is connected to the SCARA robot by means of a cross-shaped bracket 15 and a tool flange 3. The robot assembly comprises a vacuum suction rotor assembly 9, a CCD camera assembly 4, a blade furling assembly 11 and a pneumatic clamping jaw 6. The rotor is sucked at the bottom of the vacuum rotor sucking component, and the pneumatic clamping jaw 6 realizes the opening and closing of the two jaws through pneumatics, so that the grabbing and the retraction of the stator are completed.

As shown in fig. 4, the vacuum suction rotor assembly includes a suction tube 16, which is divided into an upper suction tube 17 and a lower suction tube 18, which are connected to each other by bolts. The upper suction tube is internally provided with a vacuum suction pipeline 19, the lower suction tube is provided with a plurality of suction holes 20, and the suction holes are connected with the vacuum suction pipeline. When the bottom of the suction tube is attached to the surface of the rotor, the suction tube is vacuumized, so that the rotor can be sucked at the bottom of the suction tube through the suction holes. The rotor is assembled to the vacuum pump under the drive of the SCARA robot. Before the SCARA robot assembles the rotor to the vacuum pump, the CCD camera takes a picture of the position of the vacuum pump and assembles the rotor after analyzing the position.

After the rotor is completely assembled, the rotor blades have a certain offset when the rotor is assembled to the vacuum pump, so that the rotor blades need to be finely adjusted before the stator is assembled. As shown in fig. 5, the blade furling assembly includes a blowing barrel 21, the blowing barrel is divided into an upper blowing barrel 22 and a lower blowing barrel 23, a blowing pipe 24 is arranged in the upper blowing barrel, a plurality of blowing holes 25 are arranged on the lower side wall of the lower blowing barrel, the blowing pipe 24 is arranged on the side wall of the lower blowing barrel, and the blowing pipe of the lower blowing barrel is connected with the blowing pipe and the blowing holes in the upper blowing barrel. When the rotor blade is adjusted, the whole blowing barrel covers the rotor, then a blowing pipeline of the blowing barrel is blown, wind power enters the blowing hole through the blowing pipeline and is blown out from the blowing hole, and therefore the position of the rotor blade is finely adjusted.

As shown in fig. 2, the CCD camera assembly includes a CCD camera 4 and a light source 5, which are positioned by taking a picture before the rotor and the stator are assembled, respectively.

SCARA robot (1) drives robot frock (2) and shoots rotor (10) blade (14) subassembly upper surface with CCD camera (4) and judges the rotor position and the surface defect condition, then inhale rotor subassembly (9) with the vacuum and get rotor (10), then CCD camera (4) shoots vacuum pump (12) mounted position on frock tray (13), vacuum pump (12) are packed into rotor subassembly (10), then SCARA robot (1) drives blade on robot frock (2) and draws in subassembly (11) and draw in the condition that rotor blade probably appears the position skew in drawing in, then press from both sides the stator with pneumatic clamping jaw (6), because the fit clearance between rotor (10) and stator (7) is smaller, need CCD camera (4) to take the position of rotor (10) on the vacuum pump once more, then assemble stator (7) on vacuum pump (12).
