When the unqualified printed iron passes through the inspection, the sorting air nozzle is closed, and the printed iron will be transported to the defective product collection rack through the conveyor belt for collection, which reduces the cost of the inspection system and makes it more suitable for the budget of small and medium-sized enterprises.

[0011] A pre-detection component is arranged on the side of the workbench away from the sorting frame, and the pre-detection component includes a pre-frame, a conduction roller, a support column and a pre-vision detection module. The middle part of the pre-frame is connected with the conduction roller through a bearing arrangement, the bottom end of the pre-frame is arranged with a support column, and the outer wall of one side of the top of the support column is connected with the pre-vision detection module through a rotating joint.

[0012] By adopting the above technical scheme, the bottom side of the printed iron can be inspected through the front detection component, the conductive roller can be driven by a motor to transport the printed iron, and the support column plays a supporting role to mechanically support the connection of the front visual detection module.

The middle part of the roller frame is connected to the No. 1 ventilation cylinder, and lifting rods are penetrated and connected on both sides of the top of the roller frame.

[0014] By adopting the above technical solution, the thickness of the current printed iron can be detected by the thickness detection mechanism, and the surface of the printed iron can be squeezed by the roller to make it flat and play a certain smoothing role. The lifting rod can move up and down on the top of the roller frame.

[0015] The bottom ends of the two groups of lifting rods are connected with a No. 2 ventilation cylinder, and the outer walls of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder are both sleeved with rollers. The rollers are movably connected to the No. 1 ventilation cylinder and the No. 2 ventilation cylinder through rotating rings, and the two groups of rollers are abutted against each other.

[0016] By adopting the above technical solution, the roller can roll on the outer wall of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder to facilitate the passage of the printed iron.

[0019] One end of the lifting rod away from the second ventilation cylinder passes through the roller frame and is connected to a top plate. Inductive sensors are arranged on both outer walls of the top of the roller frame. Two groups of the inductive sensors correspond to the lifting rods on both sides respectively.

[0020] By adopting the above technical solution, when the printed iron passes through, the top roller will be squeezed to drive the No. 2 ventilation cylinder and the lifting rod to move upward. The lifting rod is made of metal. When the lifting rod is lifted and displaced, it will be detected by the inductive sensor. When the distance between the lifting rod and the inductive sensor changes, the magnetic field distribution in the sensor coil will change, resulting in a change in inductance. This change in inductance can be converted into a change in voltage or current through a measuring circuit, thereby detecting the displacement or position change of the lifting rod, thereby realizing the detection of the thickness of the printed iron.

[0022] By adopting the above technical scheme, the through holes play a ventilation role so as to facilitate the adsorption of impurities on the surface of the printed iron. A dust filter is provided between the exhaust fan and the dust collecting box to prevent impurities from entering the exhaust fan. When the printed iron passes through the middle of the thickness detection mechanism, the exhaust fan can be started. The exhaust fan exhausts air from the inside of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder through the dust collecting pipe to form a negative pressure space inside them, and then performs dust suction through the ventilation groove position. Impurities on the surface of both sides of the printed iron pass through the through holes and the ventilation grooves into the inside of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder, and then are transported to the dust collecting box through the dust collecting pipe for collection, thereby realizing the cleaning of the surface while detecting the thickness of the printed iron, so that it will not be affected by surface impurities in the subsequent detection process, thereby improving the detection accuracy, improving the stability of the detection system, and being able to maintain high detection accuracy and reliability in complex environments.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the printed iron on the rear box cover passes through the top of the sorting air nozzle, the controller controls the sorting air nozzle to spray air on qualified products. After being blown by the high-speed airflow, the printed iron moves upward and abuts against the outer wall of the sorting conveyor belt, so that it is transported to the qualified product transport rack through the sorting conveyor belt for subsequent transportation and processing. When the unqualified printed iron passes through the sorting air nozzle, the sorting air nozzle is closed, and the printed iron will be transported to the defective product collection rack through the conveyor belt for collection, which reduces the cost of the detection system and makes it more suitable for the budget of small and medium-sized enterprises; 2. When the printed iron passes through the middle of the thickness detection mechanism, the exhaust fan can be started. The exhaust fan exhausts the inside of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder through the dust collecting pipe to form a negative pressure space inside, and then the dust is sucked through the ventilation groove. The impurities on the surface of both sides of the printed iron pass through the through holes and the ventilation grooves into the inside of the No. 1 ventilation cylinder and the No. 2 ventilation cylinder, and then are transported to the dust collecting box through the dust collecting pipe for collection, thereby realizing the cleaning of the surface while detecting the thickness of the printed iron, so that the subsequent detection process will not be affected by surface impurities, thereby improving the detection accuracy and the stability of the detection system.

[0035] The implementation principle of the embodiment of the present application is as follows: first, the printed iron is passed through the thickness detection mechanism 19 to detect the thickness. When the printed iron passes through, the top roller 195 is squeezed to drive the second ventilation cylinder 194 and the lifting rod 193 to move upward. The lifting rod 193 is made of metal. When the lifting rod 193 is lifted and displaced, it will be detected by the inductive sensor 199. When the distance between the lifting rod 193 and the inductive sensor 199 changes, the magnetic field distribution in the sensor coil will change, resulting in a change in inductance. This change in inductance can be converted into a change in voltage or current through a measuring circuit, thereby detecting the lifting rod.

The impurities on the surface of both sides of the printed iron pass through the through hole 20 and the ventilation groove 24 into the interior of the No. 1 ventilation cylinder 192 and the No. 2 ventilation cylinder 194, and then are transported to the dust collecting box 22 through the dust collecting pipe 23 for collection, thereby realizing the detection of the thickness of the printed iron and cleaning its surface at the same time, so that it will not be affected by surface impurities in the subsequent detection process. , which improves the detection accuracy. Then, the printed iron passes through the front detection component 18 to detect the bottom side of the printed iron. The conductive roller 182 can be driven by a motor to transport the printed iron. Then, the front visual detection module 184 detects the bottom side of the printed iron through the gap of the conductive roller 182. Then, after passing through the workbench 1, the printed iron is driven by the conveyor belt 2 to be transmitted. The front detection mechanism 3 can detect the front side of the printed iron during the transportation process. When the printed iron is transported to the bottom of the fixed frame 301, the visual detection module 302 performs surface detection, and then the detected data is transmitted to the data processor 303 for data processing. The qualified signal and the unqualified signal are then transmitted to the controller 304, and the controller 304 controls the sorting air nozzle 15 to sort the printed iron. When the qualified printed iron passes through the top of the sorting air nozzle 15 after the inspection, the controller 304 controls the sorting air nozzle 15 to spray the qualified product. The printed iron moves upward after being blown by the high-speed airflow and abuts against the outer wall of the sorting conveyor belt 13, so that it is transported to the qualified product transport rack 16 through the sorting conveyor belt 13 for subsequent transportation and processing. When the unqualified printed iron passes through the inspection, the sorting air nozzle 15 is closed, and the printed iron will be transported to the defective product collection rack 17 through the conveyor belt 2 for collection.
