At present, in order to improve the detection efficiency of the appearance of the bottle body, people have also designed an appearance detector for automatically detecting the bottle body, for example, documents with chinese authorization publication number CN208888144U and chinese authorization publication number CN109926347B disclose such detectors. This kind of detection machine is usually including the conveyer belt, conveying mechanism, the revolution mechanism of drive host computer platform (also called lower carousel) rotation, a plurality of tray subassemblies, a plurality of bottle subassemblies of pressing and being located the body detection module of the detection station department of host computer platform, conveying mechanism is again including advancing a bottle helical structure, advance a bottle star gear and go out a bottle star gear, a plurality of tray subassemblies are used for bearing the bottle that awaits measuring, it revolves together along circumference evenly installing on the host computer platform, including the rotation motor that is located the tray below in each tray subassembly, can drive each tray rotation through this rotation motor, and then drive the rotation of the bottle that awaits measuring. The plurality of bottle pressing assemblies correspond to the plurality of tray assemblies one by one and are positioned above the corresponding tray assemblies for pressing and holding the bottles to be tested positioned on the trays. During the use, the bottle that awaits measuring that the bottleneck is up is sent in proper order on the conveyer belt, this bottle that awaits measuring is enlarged in proper order with the bottle interval through advancing bottle helical structure, then enter into on the bottle star gear, advance the bottle star gear rotatory will await measuring the bottle and push in proper order on the corresponding tray on the host computer bench, when the tray revolution to detection station department, carry out the body through body detection module to the bottle that awaits measuring and detect, then detect the bottle after the completion rotatory to a bottle star gear, the rethread goes out the bottle star gear and sends back to on the conveyer belt. Therefore, the detector can realize all-around quality detection and has high detection efficiency.

But when multiple cameras are used, the manufacturing cost and subsequent processing complexity are increased. Meanwhile, a rotation motor is arranged below each tray, which also causes the increase of the manufacturing cost, and the problem of the synchronism of a plurality of motors is also considered. Moreover, the bottle body to be measured often includes the straight section of thick bamboo portion that is located the lower part and the bottleneck portion that is located the upper portion, and when the two were shot simultaneously, because of the distance difference of the two and camera, the image that often shoots has partial distortion and influences the accuracy of follow-up judgement. The bottle pressing assembly is often pressed on the bottle shoulder, so that a part of the surface of the bottle body to be detected is blocked, and the detection is incomplete. In addition, set up on the tray with the bottle bottom matched with recess that awaits measuring, when advancing the bottle star gear and rotate to push the bottle that awaits measuring in proper order on the tray, the bottle that appears awaiting measuring emptys the phenomenon easily. Therefore, a further improvement is needed for the existing bottle appearance inspection machine.
