The alcohol supply mechanism provided in the present application can deliver alcohol in a sequential and intermittent manner, thereby avoiding waste caused by excessive alcohol delivery.

[0042] In this embodiment, an electric control box 6 is fixedly connected to the lower part of the frame 1 to control the operating state of the system.

[0043] The working principle of the present invention is: when in use, first, place the material to be transported on the first conveyor belt 4, and the first conveyor belt 4 runs to transport the material forward. When the material passes through the laser sensor 17, the laser sensor 17 sends a signal. At this time, the first conveyor belt 4 stops running, and the gripper 16 of the flip assembly just completes docking with the material. It should be noted that the gripper 16 can be replaced according to the shape of the material. Common grippers 16 include pneumatic grippers, mechanical grippers, electric grippers, hydraulic grippers, and vacuum suction cup grippers. The staff can select a suitable gripper 16 to be installed on the triangular rotating arm 15 according to the needs. In the process of the material being transported along the first conveyor belt 4, the camera in the box 2 always collects the material image, and then sends the image to the background control terminal for image analysis, and then determines whether there are defects on the surface of the material. However, since the bottom end face of the material is in contact with the first conveyor belt 4, it is impossible to collect the image. Therefore, after the gripper 16 clamps the material, the flip assembly runs to flip the material 90 degrees in the vertical plane, so that the original bottom end face of the material is exposed, which is convenient for the camera to collect the complete image. The specific workflow of the flip component is as follows: the initial state of the flip component is the first state, such as Figure 4 As shown, after the gripper 16 grips the material, the first cylinder 11 of the flip assembly operates to retract the output shaft, and the first cylinder 11 drives the movable push plate 12 to slowly move backward on the top surface of the rectangular support plate 9. During the process, the movable push plate 12 drives the bar-shaped rotating arm 14 to deflect backward, and the triangular rotating arm 15 also rotates with the deflection of the bar-shaped rotating arm 14, until the bar-shaped rotating arm 14 rotates backward 90 degrees, and the gripper 16 and the material also flip 90 degrees. At this time, the flip assembly is in the second state, as shown in FIG. Figure 5shown.

[0044] After the material has been inspected, the material transfer mechanism transfers the material from the first conveyor belt 4 to the second conveyor belt 5. The specific process is: the first linear motor 20 runs and moves slowly along the first linear guide 19, so that the negative pressure suction head 23 reaches directly above the material. Then, the second cylinder 22 runs and extends the output shaft, driving the negative pressure suction head 23 to descend and contact the material. Then, the negative pressure suction head 23 runs to create a negative pressure environment to firmly suck the material. Then, the second cylinder 22 runs and retracts the output shaft to lift the material to a certain height, and then transfers the material to the top of the second conveyor belt 5 through the first linear guide 19 and the first linear motor 20.

[0045] When the material is transferred to the top of the second conveyor belt 5, the closed dust cleaning component operates to take over the material for dust cleaning, specifically: the second linear motor 25 operates to move forward along the second linear guide rail 24. During the process, the rectangular plate 27 on the support seat 26 follows the movement. After the rectangular plate 27 reaches the bottom of the material, the second cylinder 22 operates to place the material on the rectangular plate 27, and then the negative pressure suction head 23 releases the material. Then, the second linear motor 25 runs in the opposite direction along the second linear guide rail 24 to return to the initial position, and the material is also transferred to this position. Then, the third cylinder 31 of the lifting and sealing dust suction mechanism operates to extend the conveyor downward. The shaft drives the rectangular cover plate 32 to descend and cover the rectangular plate 27. Subsequently, the external high-pressure gas source connected to the air cavity 28 delivers high-pressure gas to the air cavity 28, and the external vacuum pump connected to the exhaust pipe 33 operates to extract the air in the rectangular cover plate 32. During the process, the gas in the air cavity 28 is ejected from the through hole 30 to form an airflow that bombards the surface of the material, and the strong airflow will blow off the dust attached to the surface of the material, and then it will be sucked away through the exhaust pipe 33. It should be noted that in order to prevent the material from blocking the through hole 30, the present application supports the material through the ejector pin 29 so that there is a certain gap between it and the top surface of the rectangular plate 27, thereby facilitating effective cleaning of the material.

[0046] After the material is cleaned, the lifting sealed dust suction mechanism rises, and the second linear motor 25 runs again along the second linear guide 24 to transfer the material to the bottom of the negative pressure suction head 23. The material transfer mechanism runs to take over the material again. Then, the second linear motor 25 runs to drive the rectangular plate 27 to restore the initial position, and the material transfer mechanism puts the material down on the second conveyor belt 5. The second conveyor belt 5 continues to transport the material forward. When passing through the lifting cleaning mechanism, if the material surface defect detection is qualified before, it will be allowed to pass. If the material surface defect detection is unqualified before, it will not be allowed to pass. The staff will remove these unqualified materials in time for recycling. The specific process of the lifting cleaning mechanism letting the material pass is as follows: the telescopic motor 36 runs to drive the lifting plate 35 to rise, and the rotating support seat 37 and the roller body 39 rise synchronously and no longer hinder the forward route of the second conveyor belt 5. The material passes smoothly along the second conveyor belt 5.

[0047] In addition, in order to ensure the cleanliness of the second conveyor belt 5 and prevent the dust-removed material from being contaminated again by the second conveyor belt 5, the present application cleans the second conveyor belt 5 in real time through the provided lifting cleaning mechanism. The specific process is as follows: the sponge sleeve 40 on the roller body 39 contacts the second conveyor belt 5. During the process, the roller body 39 rotates in the rotating groove 38 and triggers the alcohol supply mechanism to supply alcohol to the sponge sleeve 40. After the sponge sleeve 40 is wetted with alcohol, it can clean the second conveyor belt 5 more effectively. The specific working process of the alcohol supply mechanism is as follows: during the rotation of the roller body 39, the protrusion 42 in the annular groove 41 rotates synchronously. When the protrusion 42 rotates to the bottom position of the optical axis 46, the protrusion 42 lifts the optical axis 46, so that the optical axis 46 rises along the vertical hole 45, and finally the sealing diaphragm 47 at the top of the optical axis 46 rises to open the top opening of the first cavity 48. The alcohol in the alcohol cavity 43 enters along the top opening of the first cavity 48, and flows through the second cavity 49 to the rotating groove 38 and drips on the sponge sleeve 40. It should be noted that after the protrusion 42 is separated from the bottom end of the optical axis 46, the sealing diaphragm 47 falls to seal the top opening of the first cavity 48, and the alcohol supply mechanism stops supplying alcohol to the sponge sleeve 40. This setting is to enable sequential and intermittent delivery of alcohol to avoid waste caused by excessive alcohol delivery.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
