TECHNICAL FIELD
[0001] The application belongs to the technical field of glass bottle detection, and particularly relates to a glass bottle mouth positioning and detection device. BACKGROUND
[0002] Glass bottles are widely used for sealed packaging in various fields. The bottle mouth of a glass bottle may have defects such as cracks and notches caused by the production process. These defects may affect the appearance quality of the product, or even cause safety hazards such as breakage during transportation and use.
[0003] In the prior art, the defects such as cracks and notches of the bottle mouth of a glass bottle can be detected by manual detection, but the efficiency and accuracy of this detection method are not high. In addition, an image detection method is also used for intelligent judgment. This method identifies the defects such as cracks and notches of the bottle mouth by performing binaryzation processing on the image of the bottle mouth after shooting the image of the bottle mouth, and recognizing the features of the image when there are cracks in the image.
[0004] In the production process, there are various types of glass bottles, and in particular, different glass bottles may have different heights. It is difficult for the fixed image collector to adapt to the detection of glass bottles of different heights. SUMMARY

[0010] As an embodiment, the detection plate and the image collector are driven to lift by a lifting frame.
[0011] Preferably, the material discharge channel only allows one glass bottle to pass through.
[0012] As an embodiment, a guard plate is further arranged on both sides of the conveying table, and a surrounding plate at the top of the guard plate forms the material discharge channel on the conveying surface of the conveying table.
[0013] Preferably, the outer side of the conveying table is further provided with a support, which is fixed with the guard plate across the conveying table.
[0014] As an implementation form, the lifting frame is fixed on the support.
[0015] The beneficial effects of the present application are:
[0016] The bottle mouth positioning assembly in the present application is used to position the bottle mouth height of the glass bottle, and then further control the image collector to rise or fall according to the positioning data to adapt to the bottle mouth position of the glass bottle, so as to accurately collect the image of the bottle mouth of the glass bottle. The device can realize continuous detection of the bottle mouth of different models of glass bottles. BRIEF DESCRIPTION OF DRAWINGS

[0019] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments. However, one skilled in the art will understand that the present application can be practiced without these details. In other instances, well-known structures have not been described in detail in order to avoid unnecessarily obscuring the description of the embodiments. Unless the context requires otherwise, throughout the specification and claims that follow, the word "comprise" is to be construed in an open, inclusive and
[0020] The glass bottle mouth positioning and detecting device described in the present application, as shown in Figure 1 and Figure 2 includes a conveying table 100 for placing and conveying glass bottles to realize continuous detection of the glass bottles; a backlight plate 200 is arranged on one side of the conveying table 100 as a background for image collection; and an image collector 300 is arranged on the other side of the conveying table 100, which takes the backlight plate 200 as a collection background to collect images of the glass bottles between the two.
[0021] Generally, a transmission roller cooperating with a conveying belt can be used as the conveying table 100 for placing and conveying glass bottles.
[0022] The backlight plate 200 and the image collector 300 are generally arranged oppositely, and the backlight plate 200 and the image collector 300 can be arranged at any position in the conveying direction of the conveying table 100.
[0023] The guard plate 110 is provided on both sides of the conveying table 100, and the top of the guard plate 110 is provided with a surrounding plate 111 which forms a discharging channel on the conveying surface of the conveying table 100. The discharging channel has a section which allows only a single glass bottle to pass through. The section which allows only a single glass bottle to pass through is arranged between the image collector 300 and the backlight plate 200, so that the image collector 300 can detect each glass bottle.
[0024] For the purpose of detecting glass bottles of different heights, the image collector 300 is arranged to be height-adjustable. In the present application, a lifting frame 410 is arranged, and the image collector 300 is mounted on the lifting frame 410. The lifting frame 410 drives the image collector 300 to adjust the height.
[0025] As an implementation manner, the lifting frame 410 drives the image collector 300 to adjust the height by means of a screw rod transmission. Generally, the lifting frame 410 includes a column, a screw rod and a motor. The screw rod is mounted in the column, and the motor is connected to one end of the screw rod through a shaft coupling. The column is provided with an opening on one side to facilitate mounting of the image collector 300. A nut which cooperates with the screw rod is mounted on the image collector 300. The nut is connected to the screw rod through the opening of the column. The image collector 300 is also abutted against the column. When the motor works, the screw rod is driven to rotate, thereby driving the image collector 300 to move along the axial direction of the screw rod.
[0026] In order to cooperate with the work of the image collector 300, a bottle mouth positioning assembly is arranged on one side of the discharging channel. The bottle mouth positioning assembly is used to position the height of the bottle mouth of the glass bottle, thereby being used to feedback control the height of the image collector 300. Therefore, the bottle mouth positioning assembly should be arranged at the front end of the image collector 300, that is, the glass bottle passes through the bottle mouth positioning assembly first and then passes through the image collector 300 in the conveying process. The bottle mouth positioning assembly includes a horizontally arranged detection plate 510 which is also arranged to be height-adjustable. In addition, a distance sensor 520 is arranged above the detection plate 510. The distance sensor 520 is used to measure the vertical distance between the detection plate 510.
[0027] In the bottle mouth positioning assembly, since some glass bottles are transparent, the bottle mouth is open, and the opening can be small and thin-walled. Direct measurement by the distance sensor 520 can cause inaccurate measurement or failure to measure the bottle mouth. The detection plate can not only accurately determine the height position of the bottle mouth, but also avoid the problem of inaccurate measurement caused by the transparent property of the glass bottle, the open bottle mouth, the small opening, the thin wall and other factors.
[0028] As an implementation manner, the lifting frame 410 can also be used to adjust the height of the detection plate 510.
[0029] The bottle mouth positioning assembly cooperates with the image collector 300 to realize the detection of glass bottles at different heights in the following manner:
[0030] When the glass bottle is driven into the discharge channel and passes through the bottle mouth positioning assembly, the detection plate 510 is controlled to move downward until it stops moving after contacting the bottle mouth of the glass bottle;
[0031] The distance sensor 520 measures the vertical distance between the detection plate 510 to form a control signal;
[0032] The image collector 300 is then controlled to move to a position flush with the bottle mouth of the glass bottle according to the control signal to complete the image collection of the bottle mouth.
[0033] Since the surrounding plate 111 forms the discharge channel on the conveying surface of the conveying table 100, part of the guard plate 110 is located on the top of the conveying table 100. A support 420 is further arranged on the outside of the conveying table 100. The support 420 is used to fix the guard plate 110, forming a mechanism similar to a cantilever beam to pull the guard plate 110, avoiding the problem of the guard plate 110 falling to contact the conveying table 100, causing the abrasion of the conveying table 100 and increasing the conveying resistance.
[0034] In addition, the lifting frame 410 can also be directly fixed on the guard plate 110.
[0035] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
