[0081] Furthermore, considering the mounting foot structure of the compressor 8 and the fact that there are three mounting foot fixing bolts, in this embodiment, each positioning mechanism includes a positioning post 10 arranged in a triangle.

[0121] Example 1:

[0122] like Figures 1-15 As shown, in this embodiment, the testing equipment includes a foot cup 2, a cabinet door 3, an industrial control computer 4, an indicator light 5, a camera scanner mounting bracket 11, a lower pressure plate mounting bracket 12, a rotating arm mounting bracket 13, a rotating disk 27, and a stepper motor 32 mounted on the main frame 1; a barcode scanner 14 and a visual infrared camera 15 mounted on the camera scanner mounting bracket 11; a cylinder 19, a platform support plate 20, a solenoid valve, a flow meter, a pressure module 21, a linear bearing 22, a positioning guide rod 23, a buffer spring 24, an intake / exhaust interface, a power interface, a vibration sensor 25, and a noise sensor 26 mounted on the lower pressure plate mounting bracket 12; a servo motor 16, a rotating bracket 17, and a laser infrared scanning module 18 mounted on the rotating arm mounting bracket 13; a rotating platform 9 and a positioning column 10 mounted on the rotating disk 27; an industrial camera 29, a three-jaw finger cylinder 30, and an L-shaped gripper 31 mounted on a robot 28; and a perimeter fence 6, a fork plate 7, a compressor 8, and a robot 28 mounted in the surrounding area of ​​the main frame 1.

[0123] Action flow:

[0124] The compressor 8 to be tested and the storage fork 7 are placed within the enclosure 6. The robot 28 has a fork 7 fully loaded with material on one side and an empty fork 7 on the other. The testing equipment is started, and the industrial control computer 4 sets the test parameters. The industrial control computer 4 automatically retrieves images from the EMS library. The robot 28 moves to a position above the fork 7 of the compressor 8. The industrial camera 29 takes pictures to position the material on the compressor 8. The robot 28 moves onto the compressor 8, and the three-jaw finger cylinder 30 drives the L-shaped gripper 31 to clamp the compressor 8. The robot 28 moves to align the mounting feet of the compressor 8 with the positioning posts 10 on the rotating disk 27, thus completing the placement and fixing of the compressor (the robot continues to move the compressor to the empty positioning post 10). Stepper motor 32 drives rotary disk 27 to rotate, causing rotary platform 9 to rotate at an angle; barcode scanner 14 scans the compressor barcode and uploads it synchronously to industrial control computer 4 system; visual infrared camera 15 performs visual inspection of the compressor appearance and label (scratches, deformation, damage, etc.) and uploads it synchronously to industrial control computer 4 system; stepper motor 32 drives rotary disk 27 to rotate, causing rotary platform 9 to rotate at an angle; servo motor 16 drives rotating bracket 17 and laser infrared scanning module 18 to rotate 360°, realizing comprehensive scanning and modeling of the compressor, and uploading it synchronously to industrial control computer 4 system; after barcode scanner 14 scans the compressor barcode and uploads it synchronously to industrial control computer 4 system, the system retrieves the corresponding barcode from MES and compresses it. The system automatically compares the dimensions and structure of the machine drawings and identifies any anomalies. Stepper motor 32 drives rotary disk 27 to rotate rotating platform 9 at an angle. Cylinder 19 drives platform support plate 20, solenoid valve, flow meter, pressure module 21, linear bearing 22, positioning guide rod 23, buffer spring 24, intake / exhaust interface, and vibration sensor 25 to press down. After the intake / exhaust interface, power interface, and vibration sensor 25 contact the compressor (inlet, exhaust port, and terminal), the positioning guide rod 23 presses the intake / exhaust interface along the linear bearing 22 under the force of buffer spring 24, preventing damage to the compressor 8. The system retrieves the operating parameters (voltage, current, frequency, etc.) of compressor 8 based on the barcode model scanned by barcode scanner 14. The compressor is started, and the vibration sensor 25 inside the intake and exhaust interface monitors the compressor's vibration in real time. The noise sensor 26 monitors the operating noise in real time. The solenoid valve, flow meter, and pressure module 21 open and close the air flow according to the test requirements to test the compressor's intake air volume, exhaust air volume, stall pressure, and operating pressure. A comprehensive test is performed according to the MES drawings in the system, and the test results are automatically compared. The stepper motor 32 drives the rotating disk 27 to rotate the rotating platform 9 at an angle. The robot 28 moves the qualified compressor 8 that has completed the test to the fork plate 7, and the unqualified products are placed on the ground and an alarm is triggered. The data is simultaneously uploaded to the industrial control computer 4, and all action information is uploaded to the MES for archiving through the industrial control computer 4. This cycle continues.

[0125] The testing equipment of this utility model adopts a universal design and is suitable for testing multiple functions. It uses a single-flow automatic intelligent testing platform, a positioning column design for installation, robot vision-guided handling, intelligent testing and automatic comparison with the library, intelligent quality judgment, and can record relevant data and upload it to the computer system.

[0126] like Figure 16 As shown, the testing method for using the testing equipment provided by this utility model includes the following steps:

[0127] Step S1: Place the compressor and forklift in the designated area, then start the test equipment and set the parameters through the industrial control computer;

[0128] Step S2: Use a robot to place the compressor at the first inspection station of the rotating platform to complete barcode scanning and appearance inspection;

[0129] Step S3: After completing the inspection at the first inspection station, the rotating platform moves the compressor to the second inspection station to perform a 360° full-scale scan and modeling of the compressor. The basic parameters are then tested by comparing the model with the drawings through the system.

[0130] Step S4: After completing the basic parameter detection, the rotating platform moves the compressor to the third detection station to perform a comprehensive test of the compressor's operating parameters, such as power, pressure, noise, and vibration.

[0131] When all tests are passed, the pass indicator light will illuminate; if any tests are failed, an alarm will sound.

[0132] When the qualified indicator light is on, the robot will move the compressor to the qualified forklift. When the unqualified alarm is triggered, the robot will move the compressor to the unqualified area.

[0133] The test data is then bound and uploaded to the MES (Manufacturing Execution System) and repeated in a loop.
