[0049] In combination with the above content and all the accompanying drawings, the working principle of the present invention is further described:

[0050] The present invention includes a speed regulating motor, two large pulleys, four small pulleys and two belts. The two parallel belts hold the bottle cap of the lotion pump to realize the transmission of the finished lotion pump; the feeding mechanism is mainly composed of two single guide rod cylinders, and the feeding of a single lotion pump is realized by staggering the telescopic state of the two single guide rod cylinders; the sorting mechanism is mainly composed of two mounting plates, two fixed guide rails, two sections of movable guide rails, and two double guide rod cylinders, wherein the two double guide rod cylinders drive the opening and closing of the movable guide rails to realize the sorting of lotion pumps; the belt transmission mechanism, the feeding mechanism and the sorting mechanism are all installed on the two vertical plates of the detection machine platform to realize the docking of each mechanism; an inspection station is set on the transmission belt, and 8 cameras and 8 light sources are arranged around the inspection station to realize the visual inspection of the lotion pump. The surface defect detection of the lotion pump 50 is the last link of the lotion pump production line. The core is to perform intelligent detection through machine vision to achieve the identification of good and bad products. According to this idea, the mechanical structure of the designed lotion pump surface defect inspection machine should realize the functions of feeding, conveying, and sorting of the lotion pump. In view of the above functions, the inspection machine is designed with a feeding mechanism, a belt transmission mechanism, a detection station, and a sorting mechanism. In terms of the overall layout, each station is linearly distributed on the belt transmission mechanism, which is the feeding station 20, the detection station 30, and the sorting station 40 in sequence. The lotion pump 50 is sequentially transmitted to each station by the belt.

[0051] The state of the feeding mechanism before feeding is that the piston rod of the first single-guide rod cylinder 32 is retracted and the piston rod of the second single-guide rod cylinder 33 is extended. Under the conveyance of the belt transmission mechanism 2, the lotion pump 50 is conveyed to the feeding mechanism. At this time, the lotion pump is blocked by the first single-guide rod cylinder 32 and is just located between the two cylinders. When the feeding mechanism is feeding, the working states of the two cylinders are switched, the piston rod of the first single-guide rod cylinder 32 is extended, and the piston rod of the second single-guide rod cylinder 33 is retracted, that is, the current lotion pump 50 is released and the next lotion pump is blocked. Under the action of the conveyor belt, the current lotion pump is conveyed to the inspection station. Subsequently, the two cylinders return to the state where the piston rod of the first single-guide rod cylinder is retracted and the piston rod of the second single-guide rod cylinder is extended, that is, the next lotion pump is allowed to enter the feeding station and wait for feeding, and the registration cycle is repeated.

[0052] After the lotion pump 50 passes through the inspection station 30 and is inspected, it is continuously conveyed to the sorting station 40. Meanwhile, the inspection system will make a judgment. If the lotion pump 50 is determined to be a defective product, the two double guide rod cylinders of the sorting mechanism will be retracted together, that is, the two movable guide rails will be pulled apart, so that the lotion pump falls into the defective product collection box under the action of gravity, and then the two movable guide rails will be closed again; if the lotion pump is determined to be a qualified product, the two movable guide rails of the sorting mechanism will not move, and the lotion pump will slide along the movable guide rails and the fixed guide rails to the qualified product collection box, wherein the movable guide rails just dock with the specified guide rails and are slightly tilted, so that the lotion pump 50 slides along the slope.

[0053] Under normal working conditions, the belt transmission mechanism works in a constant state, that is, the belt speed remains constant. The coordinated work between the feeding mechanism, the visual device, and the sorting mechanism can work under the triggering of each backup sensor, or accept instructions under the unified control of the visual system.

[0054] Although the present invention has been described according to the above preferred embodiments, there may be changes, substitutions and equivalent solutions that fall within the scope of the present invention; there may also be multiple alternative ways to implement the present invention. Therefore, it is intended that the attached claims be interpreted as including all such changes, substitutions and equivalent solutions that fall within the true spirit and scope of the present invention; those skilled in the art should understand that the present invention is not limited to the above specific embodiments, and improvements and substitutions based on the present invention using the known technology in the art fall within the scope of protection of the present invention and should be defined by the claims.
