Background
In the production process of the glass oral liquid bottle, a large amount of appearance defects and size errors are generated due to objective factors such as manufacturing process, natural gas pressure, ignition temperature, oil stain splashing, foreign matter attachment and the like. The traditional defect detection of the glass oral liquid bottle is realized by checking a backlight plate by a lamp, so that the efficiency is low, the precision is poor, and the leakage detection and the error detection are easy. Along with the development of machine vision technique in recent years, glass oral liquid bottle defect detecting system has constantly emerged, has greatly promoted detection efficiency, still has following certain or some problems in the aspect of light path design and image acquisition simultaneously:

secondly, the number of cameras is large. In order to pursue omnibearing detection, part of detection systems use four or more industrial cameras to image the same bottle, which increases the cost;
and thirdly, using a complex light source or structured light. In view of the characteristics of translucence, light reflection, surface radian and the like of the glass oral liquid bottle, part of defects can be clearly imaged only by using a coaxial light source or a plurality of strip-shaped light sources to emit structured light, so that the cost is increased;
fourthly, a transparent rotating disk is used as an imaging area platform in part of the detection system, and the scheme has large occupied space and can only receive the glass oral liquid bottles of one production line, so that the subsequent production line is not convenient to expand;
and fifthly, compressed gas is used as a power source in part of the structure, so that the whole system needs to be matched with two power sources of electricity and gas. And the pneumatic device can show slight power difference when the cylinder is under different pressures, and is not suitable for the scene with high limit precision requirement.
It is noted that the information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

The speed regulating motor 03-05, the upper chain wheel shaft 03-02a and the lower chain wheel shaft 03-02b are fixed on the bracket 03-01. The rotating shaft of the speed regulating motor 03-05 is connected with the upper chain wheel shaft 03-02a to directly provide power for the upper chain wheel shaft 03-02 a. The upper chain wheel shaft 03-02a and the lower chain wheel shaft 03-02b are sleeved with two chain wheels 04-01 a-d which are spaced at a certain distance. The distance between the two side chain wheels can be any value, and in the embodiment, the distance between the two side chain wheels is 1.5 glass oral liquid bottles.

The included angle between the formed working surface and the horizontal plane is 60-80 degrees, and 70 degrees is taken in the example. Each chain link of the chain is fixed with a U-shaped delivery groove 03-04, the U-shaped delivery grooves 03-04 span the left chain and the right chain, and the length is larger than the distance between the two chain wheels. In this example, the U-shaped shipping chute 03-04 is 2 bottles of glass oral liquid long. The U-shaped carrying groove 03-04 is a right-angle U-shaped structure as shown in fig. 6, the groove wall in the middle of the groove is higher than the groove walls at the two ends of the groove, the height of the groove wall in the middle of the groove depends on the diameter of the body of the glass oral liquid bottle to be carried, and the value of the groove wall is slightly larger than the diameter of the body. The height of the two ends of the groove wall is slightly smaller than the diameter of the body of the glass oral liquid bottle to be carried, preferably, the value in the example is slightly smaller than the radius of the body of the glass oral liquid bottle. The height of the two ends of the groove wall is smaller than that of the middle part of the groove wall so as to install the left limiting plate 03-06a and the right limiting plate 03-06 b.

Thus, the U-shaped delivery groove 03-04 moves along with the chain under the driving of the speed regulating motor 03-05, and the glass oral liquid bottle is continuously conveyed to the top end of the feeding conveying device. Each U-shaped consignment groove 03-04 can only contain one bottle, so that the feeding rhythm is guaranteed. At the lower end of the working surface, due to the large distance between the left limiting plate 03-06a and the right limiting plate 03-06b, the glass oral liquid bottle has larger redundancy when entering the working surface. Along with the gradual upward movement of the glass oral liquid bottle, the left limiting plate 03-06a and the right limiting plate 03-06b gradually move the glass oral liquid bottle to a fixed position, the glass oral liquid bottle is conveniently butted with a horizontal conveying device, after the glass oral liquid bottle bypasses the highest point of a feeding conveying device, the opening of the U-shaped carrying groove 03-04 is inclined downwards along with the chain, the glass oral liquid bottle has no stable supporting function, and the glass oral liquid bottle is poured out along with the glass oral liquid bottle.

A pair of V-shaped latch sheets corresponding to the left and the right can stably support a glass oral liquid bottle. The width of the opening of the V-shaped latch piece 05-04 is larger than the diameter of the detected bottle body of the glass oral liquid bottle. The depth of the opening depends on the arrangement direction of the glass oral liquid bottle, in the embodiment, the bottle mouth of the glass oral liquid bottle is horizontally oriented to the right, so the depth of the V-shaped opening of the V-shaped latch piece 05-04 on the left conveying chain 05-03a is deeper than that on the right conveying chain 05-03 b. Therefore, the left V-shaped latch piece is used for clamping the bottle body, the right V-shaped latch piece is used for clamping the bottle neck, the difference between the diameter of the bottle body and the diameter of the bottle neck is offset by the difference of opening depths, so that the glass oral liquid bottle on the horizontal conveying device is still kept in a horizontal state, and meanwhile, the right V-shaped latch piece is used for clamping the bottle neck of the glass oral liquid bottle by utilizing the shape characteristic of the glass oral liquid bottle, so that the position deviation of the glass oral liquid bottle in the conveying process is limited. The front end of the horizontal conveying device is vertically aligned with the upper end of the feeding conveying device. The glass oral liquid bottle rotated to the back of the feeding conveyer falls into a pair of V-shaped clamping tooth sheets of the horizontal conveyer due to the loss of the supporting function.
