Description

Technical Field

[0001] The utility model relates to the technical field of glass bottle detection, in particular to a detection mechanism for defects of the bottle mouth of a glass bottle. Background Technique

[0002] When traditional bottle inspection machines detect various glass bottles, they will transport the glass bottles through multiple sets of conveying devices, and detect the positions of the bottle body, bottle mouth, etc. of the glass bottles through a detection system during the transportation process. During the transportation of the glass bottles by the bottle inspection machine, the glass bottles will pass through a differential conveying mechanism, and the differential conveying mechanism will rub the glass bottles. The speeds of the differential belts on both sides of the glass bottle are different, and the glass bottle will rotate due to the action of friction. During this rotation process, the detection system placed on the differential conveying mechanism comprehensively detects the positions of the bottle bottom and the bottle mouth to achieve more accurate detection of the bottle body.

[0003] However, when the existing bottle inspection machine rubs the glass bottle to make it rotate, it may cause the glass bottle to shake left and right, which has an adverse impact on the detection of the detection system, resulting in insufficient reliability of the stability of the detection system. In addition, the insufficient friction of the differential belt leads to the risk of the glass bottle falling. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detection mechanism for defects of the bottle mouth of a glass bottle to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A detection mechanism for defects of the bottle mouth of a glass bottle, including a differential conveying mechanism, which enables the glass bottle to rotate during movement, facilitating comprehensive detection of the glass bottle. A plurality of electric cylinders are installed on the surface of the differential conveying mechanism. The piston rod of the electric cylinder is connected with a support bar, a driver is installed on the support bar, and a positioning belt is drivingly connected to the driver;

[0006] Two positioning belts are arranged on both sides of the bottleneck of the glass bottle to enable the glass bottle to move vertically, ensuring that the glass bottle will not tip over and fall, and being safer during detection;

[0007] A plurality of supports are installed on the side of the support bar, and a tensioner is installed on the support. The tensioner is connected with a tension pulley, and the tension pulley is in driving connection with the positioning belt surface to keep the positioning belt in a taut state and ensure that the positioning belt fits the glass bottle.

[0008] Furthermore, the differential transmission mechanism is connected to a base, on which a left camera group and a right camera group are installed. An upper camera group is installed on the upper surfaces of the left camera group and the right camera group. The left camera group, the right camera group, and the upper camera group form an EBI (empty bottle inspection system). The EBI system uses image processing technology and computer vision algorithms to achieve automatic identification and judgment of bottle defects. The intelligent and automated features reduce the need for manual intervention and improve the accuracy and consistency of inspection.

[0009] Furthermore, the tensioner includes a double-barrel shell, inside which a tension spring and a pull rod connected to the tension spring are installed. A limit head is screwed on the side of the double-barrel shell, and the limit head is connected to the other end of the tension spring. By applying a pulling force to the tension pulley through the tension spring, the tension pulley pulls the positioning belt to ensure that the positioning belt does not sag, and the positioning effect on the glass bottle is more stable.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The operation of the positioning belt is controlled by a servo motor and a driving wheel. The electric cylinder can push the two positioning belts so that the distance between the positioning belts corresponds to the bottleneck size of the glass bottle, and a certain clamping force can be applied to the bottleneck. In cooperation with the differential transmission mechanism to position the upper and lower parts of the glass bottle, it is ensured that when the positioning belt transports the glass bottle, the glass bottle will not shake or tip over, which helps to improve the detection accuracy of the right camera group, the left camera group, and the upper camera group for the glass bottle and the bottle mouth.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment:

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution: a defect detection mechanism for the bottle mouth of a glass bottle, including a differential transmission mechanism 5. A number of electric cylinders 7 are installed on the differential transmission mechanism 5. The piston rod of the electric cylinder 7 is connected to a support bar 8. A driver is installed on the support bar 8, and a positioning belt 6 is drivingly connected to the driver. The electric cylinder 7 can adjust the distance between the two positioning belts 6, change the distance between the two positioning belts 6 according to the size of the glass bottle, so that the positioning belt 6 contacts the glass bottle;

[0020] Two positioning belts 6 are provided and are located on both sides of the bottleneck of the glass bottle to enable the glass bottle to move vertically. The differential transmission mechanism 5 positions the lower part of the glass bottle, and the positioning belt 6 positions the bottleneck of the glass bottle to ensure that the glass bottle does not shake or fall during the movement;

[0021] A number of supports 18 are installed on the side of the support bar 8, and a tensioner is installed on the support 18. The tensioner is connected to a tensioning wheel 9, and the tensioning wheel 9 is drivingly connected to the positioning belt 6 to keep the positioning belt 6 in a taut state and ensure that the positioning belt 6 always contacts the bottleneck of the glass bottle.

[0022] In this embodiment, as Figure 1 shown, the differential transmission mechanism 5 is connected to a base 1. A left camera group 3 and a right camera group 2 are installed on the base 1. An upper camera group 4 is installed on the upper surfaces of the left camera group 3 and the right camera group 2. The left camera group 3, the right camera group 2, and the upper camera group 4 form an EBI (empty bottle detection system), which can cover multiple key parts such as the bottle mouth, the bottle body, and the bottle bottom, and select defective glass bottles.

[0023] In this embodiment, as Figure 2 shown, a conveyor 17 is installed on the base 1. The conveyor 17 transports the glass bottle to between the differential transmission mechanisms 5. The conveyor 17 sends the glass bottle into the detection ranges of the left camera group 3, the right camera group 2, and the upper camera group 4 to realize the automatic detection and transportation of the glass bottle.

[0024] In this embodiment, as Figure 4 and Figure 5As shown, the tensioner includes a double-barrel shell 12. Inside the double-barrel shell 12, a tension spring 15 and a pull rod 13 connected to the tension spring 15 are installed. A limit head 14 is screwed on the side of the double-barrel shell 12. The limit head 14 is connected to the other end of the tension spring 15 to fix the tension spring 15. The pull rod 13 can slide in the double-barrel shell 12. The tension spring 15 pulls the tension pulley 9 through the pull rod 13, and the tension pulley 9 tightens the positioning belt 6 to ensure that the positioning belt 6 does not sag.

[0025] In this embodiment, as Figure 5 shown, both the pull rod 13 and the limit head 14 are fixedly connected with a fixing seat 16. The fixing seat 16 is fixedly connected with the spring, realizing the fixed connection between the spring and the pull rod 13 and the limit head 14, and ensuring that the pulling force of the tension spring 15 acts on the tension pulley 9 smoothly.

[0026] In this embodiment, as Figure 3 shown, the driver includes a servo motor 11 and a driving wheel 10 connected to the servo motor 11. The positioning belt 6 is sleeved on the surface of the driving wheel 10. The servo motor 11 controls the movement of the positioning belt 6 through the driving wheel 10 and makes the movement speed of the positioning belt 6 correspond to that of the differential transmission mechanism 5.

[0027] Specifically, during use, the glass bottles placed on the conveyor 17 are sent to the left camera group 3 for detection. When the glass bottles come into contact with the differential transmission mechanism 5, the positioning belt 6 also comes into contact with the bottlenecks of the glass bottles at the same time. The differential transmission mechanism 5 rubs the glass bottles, and the glass bottles will rotate due to the action of friction, which is convenient for comprehensive detection of the glass bottles. During the rotation of the glass bottles, the servo motor 11 controls the movement of the positioning belt 6 to position the bottlenecks of the glass bottles, ensuring that the glass bottles rotate more smoothly without shaking and toppling, and guaranteeing the accuracy and safety of the glass bottle detection.
