[0023] Working process of the present invention:

[0024] In the process of using an automatic cross shaft detection device of the present invention, the cross shaft at the output end of the arranging and feeding mechanism 8 can be transferred to the cross shaft support 24 by the first material taking manipulator 3, and then the cross shaft is automatically conveyed forward by the feeding sliding seat 21. First, it moves one station to reach the end face detection station, and the end face of each shaft head of the cross shaft is detected by the end face detection device 4. When the end face detection device 4 detects, if it is qualified, the cross shaft is automatically conveyed forward by the feeding sliding seat 21, and the surface of the cross shaft is detected by the surface detection device 5; if it is unqualified, the defective product is removed by the second material taking manipulator 7. When the surface detection device 5 detects, if it is qualified, the cross shaft is returned to the lower part of the first material taking manipulator 3 to take the finished product; if it is unqualified, the defective product is removed by the second material taking manipulator 7.

[0025] Principle of end face detection: After the end face detection device 4 finishes detecting each end face, the swivel seat 23 rotates 90 degrees to enable the detection of the next end face until all four shaft heads are detected. When any one of the shaft heads is detected as unqualified, the detection stops and it is judged as a defective product. At this time, the transposition slide 22 operates to convey the cross shaft to the lower part of the movement track of the second picking manipulator 7. The second manipulator under the second lifting cylinder 72 transfers the defective product to the waste output box 13 for discharge. Then, the transposition slide 22 resets, and the feeding slide 21 returns to the lower part of the first picking manipulator 3. The first picking manipulator 3 feeds the material again to start the feeding and detection operation of the next cross shaft. When all the end faces of the shaft heads are detected as qualified, the feeding slide 21 operates again to convey the cross shaft forward to the surface detection station, and the surface detection device 5 starts the surface detection operation.

[0026] Principle of surface detection: The surface detection device 5 first detects the upper surface of the cross shaft. If the detection is qualified, the transposition slide 22 operates to convey the cross shaft to the lower part of the cross shaft turning device 6. The cross shaft is turned 180 degrees by the third manipulator 65 and then placed on the cross shaft support 24 again. Then, the transposition slide 22 resets, and the surface detection device 5 can detect the lower surface of the cross shaft. When both the upper and lower surface detections are qualified, the feeding slide 21 returns to the lower part of the first picking manipulator 3. The first picking manipulator 3 first transfers the qualified cross shaft to the finished product output device 9 for output. Then, the first picking manipulator 3 feeds the material again to start the feeding and detection operation of the next cross shaft. When any one of the detections is unqualified, the detection stops and it is judged as a defective product. At this time, the feeding slide 21 first returns to the lower part of the second picking manipulator 7, and then the transposition slide 22 operates to convey the cross shaft to the lower part of the movement track of the second picking manipulator 7. The second manipulator under the second lifting cylinder 72 transfers the defective product to the waste output box 13 for discharge. Then, the transposition slide 22 resets, and the feeding slide 21 returns to the lower part of the first picking manipulator 3. Then, the first picking manipulator 3 feeds the material again to start the feeding and detection operation of the next cross shaft.

[0027] The above embodiments are illustrative of the present invention, not restrictive thereof. Any solution obtained by simply transforming the present invention falls within the protection scope of the present invention.
