[0040] The image recognition system 3 is an image capturing device that converts the captured target into an image signal through a camera, transmits it to a dedicated image processing system, obtains the morphological information of the captured target, and converts it into a digital signal based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on site based on the results of the discrimination. The relevant technologies of the image recognition system 3 are existing technologies and will not be described in detail here.

[0041] See also Figures 6 to 8The image acquisition and recognition system 3 includes a lifting and rolling device 31, a camera device 32, a controller 33 and a position sensing device. The lifting and rolling device 31 includes a support seat 311, a lifting base 312, a lower rolling member 313, an upper rolling member 314, a rolling shaft 315 and a rolling driving member 316. The support seats 311 are relatively arranged on both sides of the positioning and conveying device 2. The lifting base 312 can be lifted and lowered between the support seats 311. The lifting base 312 is a U-shaped structure, which is arranged below the conveyor belt 21. The support arms on both sides of the U-shaped structure extend upward from the outside of the conveyor belt 21. Two lower rolling members 313 are rotatably installed on the support arms on each side to provide rolling support for the two ends of the cosmetic bottle. Two rolling shafts 315 are rotatably provided on the top of the support seat 311, and two upper rolling members 314 are fixedly provided on each rolling shaft 315 at a predetermined distance. The rolling driving member 316 is used to drive the two rolling shafts 315 to rotate synchronously in the same direction, so as to contact the upper arc surfaces of the two ends of the cosmetic bottle through the two upper rolling members 314 on each rolling shaft 315, thereby driving the cosmetic bottle to rotate between the lower rolling member 313 and the upper rolling member 314. In this embodiment, the rolling driving member 316 is fixed on the support seat 311, and drives the two rolling shafts 315 to rotate synchronously in the same direction through the gear transmission mechanism. Specifically, the output shaft of the rolling driving member 316 is connected to a rolling shaft 315 through a coupling, and a driven gear 317 is fixedly provided on each rolling shaft 315. A transmission gear 318 is rotatably provided on the support seat 311, and the transmission gear 318 is meshed and installed between the two driven gears 317. It is understood that the rolling drive member 316 can also drive each lower rolling member 313 to rotate synchronously in the same direction, or simultaneously drive each upper rolling member 314 and each lower rolling member 313 to rotate synchronously in the same direction. The camera device 32 is arranged above the lifting and rolling device 31 to collect the side image of the cosmetic bottle during the rotation process. The controller 33 ( Figure 1 The controller 33 is used to control various actions in the detection process. The controller 33 stores data of the side image of a qualified cosmetic bottle in advance. The side image data of the cosmetic bottle collected by the camera device 32 is compared with the side image data of the qualified cosmetic bottle. If the comparison results are the same, the cosmetic bottle is a qualified product, otherwise it is a failed product. In this embodiment, the controller 33 is a computer. In addition, the controller 33 can also be a PLC controller. The position sensing device is used to detect whether there is a cosmetic bottle on the positioning seat 22 transported to the corresponding position of the camera device 32, so as to determine whether the conveyor belt 21 stops rotating.

[0042] The working principle of the image acquisition and recognition system 3 is as follows: the cosmetic bottle is placed on two positioning seats 22, and the two ends of the cosmetic bottle extend from each positioning seat 22 by a predetermined distance. When the position sensing device detects the cosmetic bottle conveyed to the corresponding position of the lifting base 312, the conveyor belt 21 stops rotating, and the lifting base 312 rises, so that the lower rolling members 313 on both sides of the lifting base 312 respectively support the corresponding ends of the cosmetic bottle, and drive the cosmetic bottle to rise to the upper arc surface of the cosmetic bottle and contact each upper rolling member 314 to form a certain friction force, so that each upper rolling member 314 drives the cosmetic bottle to rotate between the lower rolling member 313 and the upper rolling member 314. During the rotation process, the cosmetic bottle collects the side image of the cosmetic bottle through the camera device 32, and the controller 33 is used to identify whether the collected side image of the cosmetic bottle is qualified, so as to control the action of the rejection device 7.

[0043] The lower rolling member 313 and the upper rolling member 314 can be rollers, drums or balls.

[0044] In order to improve the lifting stability of the lifting base 312 , a guide mechanism is provided between each support arm of the lifting base 312 and the support base 311 , and the guide mechanism includes a slider 3121 fixed on each support arm and a guide rail 3122 fixed on the support base 311 .

[0045] A lifting drive member 319 is provided at the bottom of the lifting base 312, and the lifting drive member 319 is fixed on the machine base 1. An elastic member 310 is sleeved on the lifting rod of the lifting drive member 319, and the elastic member 310 is clamped between the stopper of the lifting rod and the lifting base 312 to provide a buffering effect and reduce the impact force when the lower rolling member 313 carries the cosmetic bottle to rise and contact the upper rolling member 314. In this embodiment, the elastic member 310 is a spring.
