[0050] The debugging process of the present invention is as follows (for the debugging of the first piece of different models):

[0051] 1. Fix the tooling plate 30 through the positioning cylinder 22, and transport the toilet (first piece) to the tooling plate 30;

[0052] 2. Drive the cylinder 43 to extend the positioning plate 42, and push the toilet to be roughly aligned with the positioning plate 42;

[0053] 3. Adjust the position of the laser emitter 41 and control it to emit a cross cursor, and move the toilet to align the cross cursor with the water outlet hole of the toilet tank;

[0054] 4. After the cross cursor is aligned, adjust the position of the positioning plate 42 so that the positioning plate 42 is close to the side wall of the toilet tank, and fix the position of the positioning plate 42 through the locking handle 424;

[0055] 5. After the toilet is positioned, the lifting cylinder 631 controls the water outlet part 63 to descend, manually release water, check the flow value, and then manually control the metering water valve according to the value and the actual water volume requirement to adjust the flow value;

[0056] 6. Reset the equipment to complete the debugging.

[0057] The brief operation process of the present invention is as follows:

[0058] 1. Fix the tooling plate 30 through the positioning cylinder 22, and transport the toilet 120 to be tested to the tooling plate 30;

[0059] 2. The positioning plate 42 extends and pushes the toilet 120 to be tested, so that the side wall of the water tank of the toilet 120 to be tested is aligned with the positioning plate 42;

[0060] 3. The lifting cylinder 631 controls the water outlet part 63 to descend, the water outlet control valve 67 is opened, the trap water volume control valve 65 is opened for two seconds, and the water outlet control valve 67 is closed;

[0061] 4. The metering water discharge control valve 66 is opened (previously, during the idle time, the metering water tank control valve 64 will be opened to put in a preset amount of water);

[0062] 5. The slide plate 51 is opened, the baffle 84 is opened, the transfer basket 52 receives the test ball and transfers the test ball to the slide plate 51 under the action of the transfer cylinder 53 and drops from the slide plate 51 into the toilet, and after completion, the slide plate 51, the baffle 84 and the transfer basket 52 return to their original positions;

[0063] 6. The water outlet control valve 67 is opened to complete the flushing;

[0064] 7. The test ball is recovered by the test ball recovery assembly 80 and the toilet is determined to be qualified through the test ball counting assembly 90;

[0065] 8. Each component is reset and the toilet is transported to the assembly line or the defective product area.

[0066] In the present invention, it only requires manual handling of the toilet 120 to be tested onto the tooling plate 30 and then moving it to the assembly line after the test is completed. Automatic water testing can be achieved without installing a full set of water components, and it can be determined whether the toilet 120 to be tested is qualified based on the number of test balls flowing out after flushing, which can greatly reduce the labor intensity of workers and effectively improve the water testing efficiency.
