[0033] See also Figure 1-Figure 4An ultrasonic transmitting device 2 is installed on one side of the circular track 1, and an ultrasonic receiving transducer device 21 is fixedly installed at the rear end of the shell 10. The ultrasonic receiving transducer device 21 includes an ultrasonic receiving transducer chip and an adaptation circuit module.

[0034] Working principle: because the moving disk 11 will only stay at the upper left of the circular track 1 for 10 seconds, after a staff member places the mold to be tested on the turntable 12 on the left within 10 seconds, the double-axis motor 24 will start to reverse, and the two output shafts of the double-axis motor 24 will rotate counterclockwise, and the lower output shaft drives the rotating drum 27 to rotate counterclockwise, and the rotating drum 27 drives the pawl 28 to perform counterclockwise circular motion. At this time, the pawl 28 drives the inner ratchet 26 to rotate counterclockwise, and the inner ratchet 26 drives the rotating sleeve 30 to rotate counterclockwise, and the rotating sleeve 30 drives the lower end of the rotating shaft 25 to rotate counterclockwise, and the rotating shaft 25 drives the gear 14 to rotate counterclockwise. As the gear 14 engages with the annular gear set 13, the gear 14 rotates along the annular gear set 13. The group 13 moves counterclockwise, so that the shell 10 can be used to drive the moving disk 11 to move counterclockwise to just below the beam 6, and the moving disk 11 is located between the columns 4. At this time, the light of the photoelectric sensor 5 is blocked, and the photoelectric sensor 5 transmits a signal to the PLC controller 8. The PLC controller 8 controls the side industrial camera component 7 and the top industrial camera component 9 to take pictures of the side and top surfaces of the mold to detect the appearance. When the moving disk 11 moves counterclockwise from the left to just below the beam 6, the shell 10 drives the guide block 17 to slide along the annular guide rail 15, and the magnetic head moves a certain distance close to the annular magnetic grid strip 16. At this time, the detection circuit board receives the signal of the magnetic head and then transmits it to the control board 31. The control board 31 At the same time, the double-axis motor 24 is controlled to rotate forward, and the two output shafts of the double-axis motor 24 rotate clockwise, the upper output shaft drives the rotating drum 27 to rotate clockwise, and the rotating drum 27 drives the pawl 28 to perform clockwise circular motion. At this time, the pawl 28 drives the inner ratchet 26 to rotate clockwise, and the inner ratchet 26 drives the rotating sleeve 30 to rotate clockwise, and the rotating sleeve 30 drives the upper rotating shaft 25 to rotate clockwise, and the upper rotating shaft 25 drives the turntable 12 to rotate 360 ​​degrees clockwise. In this process, the control board 31 controls the double-axis motor 24 to rotate forward for 10 seconds and then reverse. The double-axis motor 24 rotates exactly one circle, and the lower output shaft of the double-axis motor 24 drives the lower rotating drum 27 to rotate clockwise, while the lower rotating drum 27 does not rotate clockwise. The inner ratchet 26 will be driven by the pawl 28 to rotate clockwise, so that the movable disk 11 just stops moving. After 10 seconds, the dual-axis motor 24 continues to reverse until the movable disk 11 returns to the left. The head assembly 18 transmits the signal moving along the annular magnetic grid strip 16 to the control board 31. The control board 31 controls the dual-axis motor 24 to stop for 10 seconds and then continue to reverse. During this time period, the staff will turn the mold upside down and return it to the movable disk 11. Then the dual-axis motor 24 reverses to move the movable disk 11 to the bottom of the beam 6 for another inspection, so that the mold can be fully inspected. After the inspection, until the movable disk 11 returns to the left again, the mold that has been inspected in appearance is retrieved to complete the mold appearance inspection.

[0035] See also Figure 1-Figure 7 A mold appearance detection method, based on the above-mentioned mold appearance detection device, specifically includes the following steps:

[0036] S1. Place the mold to be tested on the left turntable 12. The dual-axis motor 24 reverses and uses the ratchet and pawl assembly at the lower end to drive the gear 14 to rotate counterclockwise. The gear 14 meshes with the annular gear set 13 to drive the movable disk 11 to move counterclockwise in a circular motion.

[0037] S2, after the moving plate 11 moves to the position directly below the beam 6, the light from the photoelectric sensor 5 is blocked, and the PLC controller 8 controls the side industrial camera assembly 7 and the top industrial camera assembly 9 to take pictures of the side and top surfaces of the mold;

[0038] S3, while taking photos in S2, the magnetic head assembly 18 transmits the signal moving along the annular magnetic grid strip 16 to the control board 31, and the control board 31 controls the dual-axis motor 24 to rotate one circle in the positive direction for 10 seconds, and uses the ratchet pawl assembly at the upper end to drive the turntable 12 to rotate 360 ​​degrees clockwise;

[0039] S4. After the dual-axis motor 24 rotates forward for one circle, the control board 31 controls the dual-axis motor 24 to continue to reverse until the moving disk 11 returns to the left. The magnetic head assembly 18 transmits the signal moving along the annular magnetic grid strip 16 to the control board 31. The control board 31 controls the dual-axis motor 24 to stop for 10 seconds and then continue to reverse. During this time period, the staff turns the mold upside down and puts it back on the moving disk 11, repeats steps S1 to S3, and takes back the mold after the appearance inspection until the moving disk 11 returns to the left again, and completes the mold appearance inspection.

[0040] In summary, by placing the mold to be inspected on the turntable 12 on the left, the double-axis motor 24 is reversed and the ratchet pawl assembly at the lower end is used to drive the gear 14 to rotate counterclockwise, and the gear 14 is meshed with the annular gear set 13 to drive the movable disk 11 to move counterclockwise. After the movable disk 11 moves to the bottom of the beam 6, the light of the photoelectric sensor 5 is blocked, and the PLC controller 8 controls the side industrial camera assembly 7 and the top industrial camera assembly 9 to take pictures of the side and top surfaces of the mold. At the same time, the control board 31 controls the double-axis motor 24 to rotate forward one circle, and the ratchet pawl assembly at the upper end is used to drive the turntable 12 to rotate clockwise by 360 degrees. After the double-axis motor 24 rotates forward one circle, the control board 31 controls the double-axis motor 24 to continue to reverse until the movable disk 11 returns to the left, and then the staff turns the mold upside down and puts it back on the movable disk 11, and finally the movable disk 11 moves again to the bottom of the beam 6. In this way, the detection reduces labor and can be operated by one person. At the same time, there is no need to manually move the position, which is conducive to realizing the automatic detection of the appearance of the mold.
