Two slide bars 19 are slidably connected to the two frames 9. The two slide bars 19 are symmetrically arranged. The mobile frame 20 is connected to the front and rear sides of the two slide bars 19. The slide bars 19 are sleeved with second springs 21. One end of the second spring 21 and the front mobile frame 20 is connected, the other end of the second spring 21 is connected to the frame 9 on the front side, the second spring 21 is sleeved on the slide bar 19, which can prevent the second spring 21 from bending, and inclined openings 22 are provided on the left and right sides of the lower part of the mobile frame 20, and the left and right sides of the rear side of the frame 9 on the rear side are connected with connecting plates 221 by bolts, and a rotating frame 23 is rotatably connected between the two connecting plates 221, and the front side of the first conveyor 3 is also rotatably connected to the rotating frame 23, and rollers 24 are rotatably connected in the rotating frame 23 at even intervals, and pulleys 25 are rotatably connected on the left and right sides of the rotating frame 23, and the four pulleys 25 are respectively located in the four inclined openings 22.

[0030] like Fig.10As shown, the rotating mechanism includes a bidirectional screw rod 26, a stepper motor 27, a slide plate 28, a servo motor 29 and a clamp plate 30. The bidirectional screw rod 26 is rotatably connected in the lifting frame 7, and the rear end of the bidirectional screw rod 26 extends out from the rear side of the lifting frame 7. The stepper motor 27 is installed on the rear side of the lifting frame 7 by bolts. The output shaft of the stepper motor 27 and the rear end of the bidirectional screw rod 26 are connected by a coupling. The stepper motor 27 and the controller 111 are electrically connected. The slide plates 28 are slidably connected on both the front and rear sides of the lifting frame 7. The two slide plates 28 are threadedly connected to the bidirectional screw rod 26. The threads on the two slide plates 28 are in opposite directions, so that the bidirectional screw rod 26 can drive the two slide plates 28 to move in opposite directions. The servo motor 29 is installed on the side away from each other at the lower part of the two slide plates 28 by bolts. The servo motor 29 and the controller 111 are electrically connected.

[0032] like Figure 4 As shown, it also includes rollers 33, and the top of the baffle 14 is evenly spaced and rotatably connected to the rollers 33. When the inclined part of the push plate 16 pushes the baffle 14 to move downward, the rollers 33 can reduce the friction between the push plate 16 and the baffle 14, thereby avoiding wear of the push plate 16 and the baffle 14.

[0033] like Fig.10 As shown, a pressure sensor 34 is also included. The pressure sensor 34 is installed on one side of the two clamping plates 30 that are close to each other. The pressure sensor 34 is electrically connected to the controller 111.

[0034] Damage detection sensors are devices that monitor whether a structure or material is damaged or defective during use. Such sensors are widely used in construction, bridges, aerospace, machinery manufacturing and other fields to ensure the safety and reliability of the structure. The following are some common damage detection sensors and their applications: 1. Ultrasonic sensor Principle: Ultrasonic sensors detect defects and damage inside materials by emitting and receiving ultrasonic signals.

[0035] Application: Widely used in non-destructive testing of metals, composite materials, concrete and other materials.

[0036] 2. Thermal Imager Principle: Infrared thermal imagers detect the temperature distribution on the surface of materials and identify potential damage areas.

[0037] Application: Commonly used in thermal imaging detection of building structures, electrical equipment, pipelines, etc.

[0038] 3. Eddy current flaw detector Principle: Eddy current flaw detectors detect surface and near-surface defects of conductive materials by generating an alternating magnetic field.

[0039] Application: Mainly used for the detection of cracks, corrosion, material thickness, etc. of metal materials.

[0040] 4. Acoustic Emission Sensor Principle: Acoustic emission sensors detect the sound wave signals generated when the material is subjected to force to determine whether there is damage.

[0041] Application: Commonly used for real-time monitoring of pressure vessels, storage tanks, pipelines, etc.

[0042] 5. Visual inspection system Principle: The visual inspection system uses a high-resolution camera to capture images of the surface of the structure and uses image processing technology to identify damage.

[0043] Application: Widely used in the detection of surface cracks, corrosion, foreign matter, etc.

[0044] The damage detection sensor in this application preferably adopts a visual detection system, and uses the image processing technology of the visual detection system to identify whether the package is damaged.

[0045] Initially, the telescopic rod of the cylinder 6 is in an extended state; the staff uses an external conveying device to convey the package to the left side of the first conveyor 3. There is a certain distance between two adjacent packages on the external conveying device to avoid conveying too many packages to the first conveyor 3. The first conveyor 3 intermittently conveys the package to the right and conveys the package to the bottom of the second damage detection sensor 8. The output shaft of the stepper motor 27 drives the bidirectional screw rod 26 to rotate, and the bidirectional screw rod 26 drives the two slides 28 to move toward each other, thereby driving the two clamping plates 30 to move toward each other. The clamping plates 30 clamp the package, and the pressure sensor 34 contacts the package. The pressure sensor 34 senses the pressure value. When the pressure value sensed by the pressure sensor 34 reaches the rated value, the pressure sensor The sensor 34 sends a signal to the controller 111, and the controller 111 controls the stepper motor 27 to turn off, and controls the clamping plate 30 to stop moving at an accurate time to prevent the package from being damaged by the clamping plate 30. At the same time, the controller 111 controls the telescopic rod of the cylinder 6 to shorten, drive the lifting frame 7 to move upward, thereby driving the package to move upward, so that the package and the first conveyor 3 are out of contact, and the package is prevented from rubbing against the first conveyor 3 during rotation. Then the controller 111 controls the output shaft of the servo motor 29 to drive the clamping plate 30 to rotate one circle, thereby driving the package to rotate one circle, so that the second damage detection sensor 8 can detect the four sides of the package, to determine whether the package is damaged. After the package rotates one circle, the output shaft of the servo motor 29 stops rotating, and the cylinder 7 stops rotating. The telescopic rod 6 is extended, driving the package to move downward and reset. At the same time, the output shaft of the stepper motor 27 drives the bidirectional screw rod 26 to rotate in the opposite direction. The bidirectional screw rod 26 drives the two clamping plates 30 to move away from each other, loosening the package. The package falls onto the first conveyor 3, and the first conveyor 3 continues to convey the package to the right. The package will move between the two first damage detection sensors 4. The first damage detection sensor 4 on the front side detects the front side of the package, and the first damage detection sensor 4 on the rear side detects the rear side of the package. If the second damage detection sensor 8 detects that the package is damaged, the controller 111 will control the first damage detection sensor 4 to turn off. At the same time, the controller 111 will control the electric guide rail 10 to operate. If the second damage detection sensor 8 If it is detected that the package is not damaged, the controller 111 will not control the first damage detection sensor 4 to turn off, and the first damage detection sensor 4 can still detect the package. If the first damage detection sensor 4 detects that the package is damaged, the controller 111 will control the electric guide rail 10 to run to avoid conflicts in program operation. If the push plate 11 is located at the rear side of the electric guide rail 10, the electric guide rail 10 drives the push plate 11 to move forward. If the push plate 11 is located at the front side of the electric guide rail 10, the electric guide rail 10 drives the push plate 11 to move backward. At this time, the push plate 11 is located at the rear side of the electric guide rail 10. Therefore, the electric guide rail 10 drives the push plate 11 and the push plate 16 to move forward, and the inclined part of the front side of the push plate 16 drives the baffle 14 to move downward.The first spring 15 is stretched, and the baffle 14 moves downward and contacts the top of the conveyor belt of the first conveyor 3. The baffle 14 can block the damaged parcels, and the push plate 11 can push the damaged parcels to the roller 24 on the front side. At the same time, the push plate 11 can push the leaked materials to the roller 24 on the front side, automatically handling the damaged parcels and the leaked materials to ensure the sorting efficiency. After the push plate 16 and the baffle 14 are out of contact, under the action of the first spring 15, the baffle 14 moves upward to reset, and the push plate 11 continues to move forward, and the push plate 11 will push the moving frame 20 on the front side. The movable frame 20 at the front side drives the slide bar 19 to move forward, and the slide bar 19 drives the movable frame 20 at the rear side to move forward. The second spring 21 is compressed, and the movable frame 20 moves forward to push the pulley 25 to move downward. The pulley 25 drives the rotating frame 23 to rotate downward, so that the rotating frame 23 is close to the second conveyor 18, and the damaged packages and leaked materials move downward along the rollers 24 at the front side to the second conveyor 18. The second conveyor 18 transports the damaged packages and leaked materials forward for easy processing, and the rotating frame 23 is close to the second conveyor 18, which can prevent the damaged packages from being directly When the push plate 11 and the push plate 16 move backward, the push plate 11 and the front moving frame 20 are out of contact. Under the action of the second spring 21, the front moving frame 20 moves backward, and the front moving frame 20 drives the slide bar 19 to move backward. The slide bar 19 drives the rear moving frame 20 to move backward. The backward movement of the moving frame 20 will push the pulley 25 to move upward, and the pulley 25 drives the rotating frame 23 to rotate upward, and the rotating frame 23 is rotated to a horizontal state. The inclined part of the rear side of the push plate 16 pushes the baffle 1 4 moves downward, the push plate 11 can push the damaged parcel to the roller 24 on the rear side, and the damaged parcel moves along the roller 24 on the rear side to the second conveyor 18. At the same time, the push plate 11 can push the leaked materials to the roller 24 on the rear side. Each movement of the push plate 11 can clean up the damaged parcels and leaked materials, and the operation is more coherent, which can ensure the sorting efficiency. The second conveyor 18 transports the damaged parcels and leaked materials forward. The staff only needs to stand in front of the second conveyor 18 to operate, and there is no need to walk back and forth, which can reduce the burden on the staff.
