Description

Technical Field

[0001] The utility model relates to the technical field of bottle mouth detection, in particular to an adaptive bottle mouth crack detection device. Background Art

[0002] During the production process of glass bottles, the generation of cracks at the bottle mouth is a common problem. Therefore, crack detection equipment is required during the production process to detect glass wine bottles and remove defective bottles to avoid product transportation and storage caused by defects in glass bottles. The patent document with the application number CN202111260527.4 previously applied by the applicant discloses a linear follow-up bottle mouth crack detection system. The glass bottle to be inspected is placed on the production line. A reciprocating follow-up module is connected above the production line and can perform periodic horizontal reciprocating motion along the running direction of the production line. A rotatable information acquisition device is rotatably connected below it. The reciprocating follow-up module drives the information acquisition device to perform linear motion following the bottle mouth. At the same time, the information acquisition device rotates to complete the bottle mouth information acquisition work. However, the reciprocating follow-up module in this system can only perform linear motion in the front and back directions. When the bottle body is too high, the reciprocating follow-up module cannot move above the bottle body following the bottle body. When the bottle body is too low, the distance between the information acquisition device and the bottle mouth is relatively far, which will affect the accuracy of bottle mouth detection. Moreover, several sampling cameras in this system are at the same height and are only for one specification of bottle body. When the bottle body specifications are different, a larger range of detection cannot be carried out. Content of the Utility Model

[0003] In order to solve the technical problems of being unable to adapt to bottle bodies of different heights and having low flexibility in the above-mentioned background art, the utility model provides an adaptive bottle mouth crack detection device.

[0004] The technical solution of the utility model is as follows:

[0005] An adaptive bottle mouth crack detection device includes a fixed frame and a detection mechanism connected to the lower side of the fixed frame through a lifting mechanism. The fixed frame includes a horizontally arranged rectangular fixing plate. The lifting mechanism includes a lead screw vertically arranged and fixed to the detection mechanism at the lower end. A driving nut screwed to the lead screw is also rotatably provided on the fixing plate. The lifting mechanism further includes a driving motor drivingly connected to the driving nut. The detection mechanism includes a main frame connected to the lead screw and a rotating bracket horizontally slidably arranged on the lower side thereof. A plurality of sampling cameras are circumferentially and arrayed on the rotating bracket with upper and lower staggered arrangements.

[0006] The driving motor drives the nut to rotate. Under the rotation of the nut, the screw drives the detection mechanism to move up and down to adapt to the bottles to be inspected at different heights. Then the detection mechanism can move horizontally with the bottle body. At the same time, the rotating bracket drives the sampling camera to rotate and take pictures of the bottle mouth for sampling. The up and down staggered sampling cameras can increase the sampling range of the camera to meet the needs of bottle mouths of different sizes.

[0007] Furthermore, at least two screw rods are symmetrically arranged along the center of the fixing plate, so as to increase the stability between the lifting mechanism and the detection mechanism and avoid shaking during the lifting process.

[0008] In order to ensure that the movement of several lead screws can be kept consistent and improve the stability of the lifting process, the driving nuts are connected to the driving motor through a synchronous belt, and the synchronous belt transmission is accurate, stable, efficient and easy to maintain.

[0009] As for the specific structure of the synchronous belt, the synchronous belt includes a transmission gear connected to the driving nut, and a belt sleeved on the outer ring of the transmission gear. The driving motor is connected to the belt through the driving gear, and the distance between the driving gear and each driving nut is the same. During the transmission process, there is no relative sliding between the belt and the transmission gear, the transmission ratio is accurate and constant, and the synchronous belt is relatively quiet during transmission without causing noise pollution. By changing the rotation direction of the driving gear, the up and down movement of the screw rod is changed, thereby realizing the rise or fall of the detection mechanism.

[0010] Preferably, the fixing plate is provided with a through hole, and the driving nut is rotatably connected in the through hole through a bearing, and the driving nut is supported by the bearing, so as to reduce the friction coefficient during its movement, ensure its rotation accuracy, reduce mechanical failures, improve transmission efficiency, and be beneficial to energy saving. It can also improve work efficiency and extend service life.

[0011] As a preferred embodiment, the lifting mechanism further comprises a guide shaft which is arranged vertically and fixedly connected to the detection mechanism at the lower end, and the fixing plate is slidably sleeved on the outer ring of the guide shaft, thereby improving the stability of the lifting process of the detection mechanism, reducing shaking, and providing a guiding function for the lifting process.

[0012] Further preferably, there are several guide shafts evenly distributed along the circumference of the fixed plate. During use, the detection mechanism not only performs lifting movement but also needs to perform lateral movement. Several evenly arranged guide shafts can improve the stability of the overall structure and prevent the lifting mechanism from tilting or shaking during the lateral movement of the detection mechanism.

[0013] As a preferred embodiment, an even number of sampling cameras are circumferentially arranged along the rotation axis of the rotating bracket, and the two relatively arranged sampling cameras have the same height. The vertically staggered sampling cameras can increase the sampling range of the cameras, meet the requirements of bottle mouths of different sizes. At the same time, the setting of an even number ensures that there are at least two relatively arranged sampling cameras for taking pictures at any angle, ensuring the accuracy of sampling.

[0014] Through the above design, the beneficial effects of the present utility model are as follows:

[0015] 1), Through the setting of the lifting mechanism, the detection mechanism can be moved up and down, ensuring a suitable distance between the sampling camera and the bottle mouth of the bottle to be inspected, so that the detection mechanism can adapt to bottles of different specifications.

[0016] 2), Through the vertically staggered sampling cameras, the sampling range of the cameras can be increased, meeting the requirements of bottle mouths of different sizes. At the same time, the setting of an even number ensures that there are at least two relatively arranged sampling cameras for taking pictures at any angle, improving the accuracy of sampling.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiment

[0024] Combined with Figures 1 to 3 , this embodiment provides an adaptive bottle mouth crack detection device, including a fixed frame and a detection mechanism 3 connected to its lower side through a lifting mechanism 2.

[0025] In this embodiment, the fixing frame includes a rectangular fixing plate 1 arranged horizontally. The lifting mechanism 2 includes a lead screw 21 arranged vertically with its lower end fixed to the detecting mechanism 3. A driving nut 22 that is in screw connection with the lead screw 21 is rotatably provided on the fixing plate 1.

[0026] Preferably, a through hole is provided on the fixing plate 1, and the driving nut 22 is rotatably connected to the through hole through a bearing. By supporting the driving nut 22 with the bearing, the friction coefficient during its movement is reduced, its rotation accuracy is ensured, mechanical failures are reduced, and at the same time, the transmission efficiency is improved, which is beneficial to energy saving. Moreover, it can improve work efficiency and extend service life.

[0027] Further, at least two lead screws 21 are symmetrically arranged along the center of the fixing plate 1 to increase the stability between the lifting mechanism 2 and the detecting mechanism 3 and prevent shaking during lifting.

[0028] As a preferred implementation manner, the lifting mechanism 2 further includes a guide shaft 25 arranged vertically with its lower end fixedly connected to the detecting mechanism 3. The fixing plate 1 is slidably sleeved on the outer circle of the guide shaft 25. This improves the stability of the detecting mechanism 3 during lifting, reduces shaking, and provides a guiding function for its lifting process.

[0029] More preferably, a number of guide shafts 25 are evenly distributed along the circumference of the fixing plate 1. During use, the detecting mechanism 3 not only moves up and down but also needs to move horizontally. The number of evenly arranged guide shafts 25 can improve the overall structural stability and prevent the lifting mechanism 2 from tilting or shaking during the horizontal movement of the detecting mechanism 3.

[0030] Preferably, connection heads are provided at the lower ends of both the guide shaft 25 and the lead screw 21 to be connected and fixed to the detecting mechanism 3, increasing the contact area between the detecting mechanism 3 and the guide shaft 25 and the lead screw, and improving stability.

[0031] In this embodiment, the lifting mechanism 2 further includes a driving motor 23 that is in transmission connection with the driving nut 22.

[0032] The driving motor 23 is installed on the fixing plate 1 and is located in the middle of a number of lead screws 21, which can not only maintain the stability of the center of gravity but also save space, and the overall structure is compact.

[0033] To ensure that the movement of a number of lead screws can be consistent and improve the stability during lifting, the driving nuts 22 are in transmission connection with the driving motor 23 through a synchronous belt 24. Moreover, the synchronous belt 24 has accurate, stable transmission, high efficiency, and is convenient for maintenance.

[0034] Combined with Figure 3, in terms of the specific structure of the timing belt 24, the timing belt 24 includes a transmission gear 241 drivingly connected to the driving nut 22, and a belt 242 sleeved on the outer circle of the transmission gear 241. The driving motor 23 is drivingly connected to the belt 242 through a driving gear, and the distances between the driving gear and the driving nuts 22 are the same. During the transmission process, there is no relative sliding between the belt 242 and the transmission gear 241, the transmission ratio is precisely constant, and the timing belt 24 is relatively quiet during transmission without causing noise pollution. By changing the rotation direction of the driving gear, the up and down movement of the lead screw 21 is changed, so as to realize the lifting or lowering of the detection mechanism 3.

[0035] In a specific implementation, a tension pulley 243 is provided between the outer circle of the belt 242 and between the transmission gear 241 and the driving gear. The fixing plate 1 is provided with a slotted hole. The upper side of the tension pulley 243 is slidably connected to the slotted hole through a connecting member and is connected with a fastening member capable of fixing the position of the tension pulley 243 and the slotted hole. By providing the tension pulley 243, the path and tension of the belt 242 can be adjusted, and vibration and noise can be reduced.

[0036] In this embodiment, the detection mechanism 3 includes a main frame connected to the lead screw 21, and a rotating bracket 31 slidably arranged horizontally on the lower side thereof. A plurality of sampling cameras 32 arranged in a circumferential array and staggered up and down are provided on the rotating bracket 31.

[0037] As a preferred implementation manner, an even number of the sampling cameras 32 are circumferentially and evenly arranged along the rotation axis of the rotating bracket 31, and the two relatively arranged sampling cameras 32 have the same height. The sampling cameras 32 staggered up and down can increase the sampling range of the cameras and meet the requirements of different-sized bottle mouths. At the same time, the setting of an even number ensures that there are at least two relatively arranged sampling cameras 32 for taking pictures at any angle, ensuring the accuracy of sampling.

[0038] The driving motor 23 drives the nut 22 to rotate. Under the rotation of the nut, the lead screw 21 drives the detection mechanism 3 to move up and down to adapt to the to-be-inspected bottle bodies of different heights. Subsequently, the detection mechanism 3 can move horizontally following the bottle body. At the same time, the rotating bracket 31 drives the sampling cameras 32 to rotate and take pictures of the bottle mouth for sampling. The sampling cameras 32 staggered up and down can increase the sampling range of the cameras and meet the requirements of different-sized bottle mouths.

[0039] Exemplarily, the adaptive bottle mouth crack detection device further includes a collection module capable of acquiring bottle body information. When the bottle to be inspected enters the detection line, the collection module first acquires the bottle body height information, controls the driving motor 23 to act according to the bottle body height information, operates the lead screw to lift to match the bottle body height. After the height adjustment is completed, the sampling camera 32 is aligned with the bottle mouth, and driven by the rotating bracket 31, it moves a certain distance following the bottle mouth and takes rotating pictures at the same time. After the photographing and sampling are completed, the next bottle to be inspected enters the detection line. At this time, the collection module acquires the bottle body height information again. If the height changes, the detection mechanism 3 starts to perform lifting adjustment during the process of returning to the initial position. If the bottle body height does not change, the previous height is maintained and only horizontal displacement is performed.

[0040] With the arrangement of the lifting mechanism 2 in the present utility model, the detection mechanism 3 can move up and down, ensuring an appropriate distance between the sampling camera 32 and the bottle mouth of the bottle to be inspected, so that the detection mechanism 3 can adapt to bottles of different specifications. Through the sampling cameras 32 arranged in a staggered up and down manner, the sampling range of the cameras can be increased to meet the requirements of bottle mouths of different sizes. At the same time, the even number setting ensures that there are at least two opposite sampling cameras 32 for photographing at any angle, improving the accuracy of sampling.
