The NG rejection mechanism 15 is used to reject defective bottle caps with quality problems after being inspected by the front detection mechanism 13 and the side detection mechanism 14. A defective output slide 21 is arranged on the front conveyor belt 12 on the side opposite to the NG rejection mechanism 15. The defective caps rejected by the NG rejection mechanism 15 are transferred to the defective output slide 21 by force for output, and then the caps meeting the front / side quality requirements continue to be transferred backwards. The output end of the front / side transmission detection unit is contact-connected with a reverse transmission detection unit, which is used to perform reverse quality inspection on the caps. The reverse transmission detection unit includes a reverse conveyor belt 16 which is contact-connected with the front conveyor belt 12. An adsorption mechanism is arranged on the reverse conveyor belt 16. The adsorption mechanism is used to adsorb and fix the caps transferred to the reverse conveyor belt 16, and then automatically move backwards under the transfer of the reverse conveyor belt 16 of the caps. A reverse detection mechanism 19 is arranged below the bottom of the reverse conveyor belt 16. The reverse detection mechanism 19 performs online quality detection on the reverse side of the caps adsorbed on the reverse conveyor belt 16. An NG rejection mechanism 15 is also arranged on the side of the reverse conveyor belt 16 located at the rear side of the reverse detection mechanism 19, and a defective product output slide 21 is arranged on the reverse conveyor belt 16 on the side opposite to the NG rejection mechanism 15, that is, Under the detection of the back side detection mechanism 19, the defective caps are removed and output to the defective output slide 21, and then the caps that have passed the above-mentioned quality inspection are transferred backwards, and the output end of the back side conveyor belt 16 is connected to a good product collection bin 17, and the good product collection bin 17 is used to collect the caps that meet the quality inspection. A misaligned collection cylinder 20 is provided at the top of the good product collection bin 17 at the output end of the back side conveyor belt 16, and the misaligned collection cylinder 20 is used to force the caps to be output and adsorbed on the back side conveyor belt 16 to be separated, and the caps are automatically transferred to the good product collection bin 17 for storage; through the automated coordination between the above-mentioned front / side transmission detection unit and the back side transmission detection unit, large quantities of caps can be intelligently and quickly inspected online.

[0016] In the embodiment of the present invention, the riveting machine 10 is a device for connecting two or more workpieces, which is usually used in the manufacturing and assembly process to permanently connect the parts together through rivets, screws or other connectors. In the present device, it is mainly used to rivet the top of the bottle cap with the bottom plate component to form a complete bottle;

[0017] In one embodiment of the present invention, the bottom of the riveting machine 10, the front / side transmission detection unit, and the back transmission detection unit are all installed with a device box through various brackets, and the device box is used to support the above structures and store components; wherein, the bottom of the good product collection bin 17 is connected with a truncated cone-shaped structure leg, and the bottom of the leg is directly placed on the ground to stably support the operation of the good product collection bin 17;

[0018] Specifically, the components of the front detection mechanism 13, the side detection mechanism 14 and the back detection mechanism 19 are the same, and all include a fiber optic sensor, a shooting device (such as a camera), and a data processing system. The fiber optic sensor is placed on the front side of the shooting device, that is, when the cover moves along the front conveyor belt 12 and the back conveyor belt 16 to the front of the shooting device, the fiber optic sensor senses the product, and then the shooting device starts to shoot the front / side / back surface of the passing cover, and the photographed information is transmitted to the data processing system, and then processed and analyzed to determine whether the cover meets the requirements, and then the corresponding NG rejection mechanism 15 is controlled to operate, and the defective cover is rejected and output toward the defective product output slide 21 on the corresponding side, wherein the NG rejection mechanism 15 is connected and coordinated with the data processing system for operation. When a defective product is detected, the data processing system will send a signal to the control system to notify the occurrence of the relevant problem. After receiving the signal, the control system will trigger the rejection mechanism to perform corresponding actions, thereby transferring the defective product to the defective product output slide 21;

[0019] The rejecting mechanism in the above-mentioned NG rejecting mechanism 15 includes equipment such as a robot arm, a pneumatic device, and a solenoid valve. As the connection and operation between the above-mentioned structures belong to the existing technology, they will not be described in detail here.

[0020] As a preferred embodiment of the present invention, the adsorption mechanism includes adsorption holes opened along the surface of the reverse conveyor belt 16 in the transmission direction, and the inner side of the adsorption hole is connected to a suction pipe 18, and the end of the suction pipe 18 is connected to a suction fan. Under the continuous adsorption action of the suction fan, in conjunction with the transmission of the suction pipe 18, each adsorption hole on the reverse conveyor belt 16 is maintained to have an effective adsorption capacity, and the lids transferred to the reverse conveyor belt 16 are stably adsorbed;

[0021] Among them, it should be noted that when the cover is placed on the front conveyor belt 12 for transfer, it is placed along the upper side of the front conveyor belt 12 and transported stably. When it is transferred to the reverse conveyor belt 16, it is adsorbed by the adsorption holes in advance and then fixed on the reverse conveyor belt 16. At this time, the reverse conveyor belt 16 rotates in the opposite direction to the front conveyor belt 12, thereby transferring the cover backward along the lower side of the reverse conveyor belt 16, thereby ensuring that the reverse detection mechanism 19 placed under the reverse conveyor belt 16 can fully detect the reverse side of the cover.

[0022] The working principle of the utility model is: in the idle part of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. The bottle caps processed and riveted by the riveting machine 10 are transferred along the transmission slide 11 to the front conveyor belt 12, and then the front conveyor belt 12 is used for automatic transportation, and the front and side detection mechanisms 13 and 14 on the front conveyor belt 12 are used for the front and side detection mechanisms 14. The side is photographed for quality inspection, and then the defective caps detected are transferred to the defective output chute 21 for output under the action of the NG rejection mechanism 15, and then the caps that meet the quality requirements on the front and side continue to be transferred backward to the reverse conveyor belt 16, and are fixed by the adsorption holes on the reverse conveyor belt 16, and then transferred to the bottom of the reverse conveyor belt 16, and the reverse side is inspected by the reverse detection mechanism 19, and then the defective products are continuously output with the cooperation of the NG rejection mechanism 15 and the defective output chute 21, and the caps that meet the quality requirements are transferred to the good product collection bin 17 for storage under the action of the offset collection cylinder 20.
