Description

Bottle body detection device and detection method thereof

Technical Field

The invention relates to the technical field of bottle body detection, in particular to a bottle body detection device and a detection method thereof.

Background

After the bottle body is produced, the bottle body is required to be packaged after being detected, the bottle body is detected in different detection modes according to different requirements, for example, under the conditions that the air tightness requirement of the bottle body is high and the appearance and the size requirement are not high, only the defects of the bottle body, such as cracks, broken openings, explosion openings and the like, which affect the air tightness are required to be detected, when the air tightness or the appearance of the bottle body is required to be higher, the defects of the bottle body, which affect the air tightness, are required to be detected, the defects of the bottle body, such as the shape specification, the size specification, the impurity condition and gas lines caused by forming, and the like, are required to be detected, in the prior art, the defects of the bottle body are detected by matching an artificial intelligent deep learning method through visual detection, the detection mode is based on the image data of the bottle body collected by an image collecting part of a detection device, the detection device is externally connected with an industrial personal computer with a visual detection technology, and the defects of the bottle body are judged according to the received image data.

For the comprehensiveness of guaranteeing image data acquisition, need to make the bottle rotate at image data acquisition in-process to a plurality of positions homoenergetic of guaranteeing the bottle are shot. The specific bottle detection process is as follows: two guide pulleys on the lift seat jack-up the bottle from the body both sides (two guide pulleys are parallel with the bottle, be formed with the clearance space between two guide pulleys, in order to make things convenient for when the guide pulley supports the bottle, for the rotation of follow-up bottle leaves pivoted space, the guide pulley can adopt the bearing, also can adopt the commentaries on classics roller, as long as the guide pulley can the rotation can), until the bottle by the jacking offset with the friction pulley directly over two guide pulleys, rotate because of the friction pulley and make and produce frictional force between friction pulley and the bottle, this frictional force impels the bottle to realize the rotation under the cooperation support of two rotation guide pulleys. In the bottle body rotation process, a plurality of image acquisition modules of the image acquisition component respectively acquire image data of the bottle bottom, the bottle body, the bottle neck and the bottle mouth of the bottle body.

At present, aiming at the inspection of a bottle body, under the condition that the requirement on the bottle body is not high, the data acquisition of the bottle bottom, the bottle body, the bottle neck and the bottle mouth can meet the detection requirement, but for some bottle bodies with high requirements, the data quantity of image acquisition data of the bottle body, the bottle bottom, the bottle neck or the bottle mouth is only increased during the detection so as to improve the accuracy of the detection, but the situation that a bottle body user thinks that the bottle body has defects of cracks, crevasses, explosion openings and the like to bring use problems still exists, for example, some bottle bodies for medicines (called medicine bottles for short) need to contain solvents, powders or granular medicines in the use process, the storage of the medicines all needs extremely high sealing performance, and once the bottle body has cracks or the crevasses, the cracks and the like which are difficult to find all influence the sealing performance of the bottle body and the strength of the bottle body in the use process; for example, in the existing market, the situation that penicillin bottles used for containing vaccines are called back in batches due to the fact that cracks exist in the bottles after the vaccines are produced appears. In addition, some medicine bottles also need to be subjected to freeze-drying preservation, so that the environment where the bottle bodies are located is very strict, the probability of bottle body breakage in the freeze-drying process is very low, but once the bottle body breakage occurs, the bottle body breakage is a very serious problem, and the problem that products in the bottles are lost or even overflow of the products and the pollution of broken glass slag to the inside of equipment are caused is caused.

Disclosure of Invention

The invention aims to provide a bottle body detection device to solve the problem that an image acquisition part in the prior art cannot detect bottle body defects more comprehensively.

In order to achieve the purpose, the invention adopts the following technical scheme:

The principle and the advantages of the scheme are as follows: in practical application, the inner wall position of the bottle mouth and the edge angle position of the inner edge of the end face of the bottle mouth can be detected by additionally arranging the inner side image acquisition module; in the prior art, for the detection of a bottle body, when the bottle mouth is located at the position of the bottle body, the bottle cap can be used together with the bottle cap, the bottle cap has a reinforcing effect on the sealing property and the strength of the bottle mouth, so the bottle cap is often overlooked, the defect condition of the outer surface of the bottle mouth is basically detected when the bottle mouth of the bottle body is detected, the defect condition of the position of the inner wall of the bottle mouth cannot be detected, the edge angle position of the inner edge of the end face of the bottle mouth is overlooked more easily, but the edge angle position of the inner edge of the end face of the bottle mouth is located at the corner between the end face of the bottle mouth and the inner wall of the bottle mouth, the size of the corner angle position is very small relative to the size of the whole bottle mouth and is overlooked easily, the wall thickness of the bottle mouth of the medicine bottle is also thick, and the condition that the edge angle position of the inner edge of the end face of the bottle mouth is overlooked is increased; through the research of the inventor, although the edge angle position of the inner edge of the end face of the bottle opening is small, once the edge angle position of the inner edge of the end face of the bottle opening has cracks, the sealing performance of the bottle opening is greatly reduced in a severe environment, if the bottle opening is dirty, the dirty easily enters the bottle body, and then the quality of the bottle body accommodating object is influenced.

Further, as an improvement, a light source is fixed on the rack, the light source is parallel to the bottle body, a bottle mouth image acquisition module is arranged in the image acquisition component and used for acquiring image data of the bottle mouth, and the bottle mouth image acquisition module is positioned in front of the bottle mouth.

Has the advantages that: according to the scheme, the light source is arranged, so that the bottleneck image acquisition module acquires image data of the bottleneck in a side light polishing mode, the acquired bottleneck image data are obviously provided with two dark areas and two light areas, the connecting line of the two dark areas is vertical to the connecting line of the light areas and the light source, and the light areas are close to the light source; the position setting of bottleneck image acquisition module, bottle and light source is passed through to this scheme for dark zone sees bottleneck surface and the cracked reflection of light of bottleneck edges and corners department crackle more clearly, and also can accurately detect the dirty and fracture etc. on surface in bright zone, has improved the accuracy that detects. Compared with the mode that the light source placed at the bottom of the bottle body and the light source on the side edge of the bottle body are integrated to polish the bottle opening camera in the prior art, the method has the advantages that the dark area is darker after the bottom light source is omitted, cracks in the dark area are more obvious, the detection accuracy is improved, the bottom light source is omitted, and the cost is reduced.

Further, as an improvement, bottleneck image acquisition module includes camera subassembly and mounting bracket, and the connection can be dismantled on the mounting bracket to the camera subassembly, is equipped with the angle modulation hole on the mounting bracket, and the camera subassembly passes through the angle modulation hole and realizes that the shooting direction of camera subassembly is adjusted, and the connection can be dismantled in the frame to the mounting bracket.

Has the beneficial effects that: in the existing bottle body detection, a detected bottle body is continuously conveyed forwards by a rotary conveyor, the bottle body is quickly jacked upwards by a lifting seat to reach the position of a friction wheel in the conveying process, and rotation detection is carried out, if the speed of the detected bottle body is too low, the detected bottle body becomes a bottleneck of production, and the production efficiency is influenced; however, if the detection speed is increased, for example, the bottle detection only takes several seconds or even about 1 second, although the starting point of the method is to increase the detection speed, in practical verification, the method is found to easily cause the bottle to fall off, a part of the bottles fall off from two guide wheels in the lifting process before detection, and even if the detection of the part of the bottles is completed, the part of the bottles also fall off in the falling process, so that the rejection rate of the bottles is increased suddenly.

Through the intensive research of the inventor, the bottle body is found to be easy to drop in a rising stage or a falling stage and has a great relationship with the rapid rising and falling of the lifting seat, the guide wheel on the lifting seat can cause the smooth bottle body to have a tendency of being thrown upwards due to sudden upward supporting force (overweight), the contact between the guide wheel and the bottle body is linear contact, and the length of the contact line is greatly smaller than that of the bottle body, so that the bottle body cannot be stably placed on the guide wheel and then drops; when the bottle body is detected to fall, the falling speed of the lifting seat is higher than that of the bottle body, the bottle body is easily in a weightless state, the problem that the bottle body still cannot be stably placed on the guide wheel is caused, and the bottle body finally easily falls.

According to the scheme, before bottle body detection, the friction wheel is located at the lowest position under the self gravity and the gravity of the vertical sliding frame, when a bottle body needs to be detected, the bottle body is driven by the lifting seat to ascend, after the lifting seat ascends in a small range, the bottle body on the lifting seat is abutted against the bottom of the friction wheel until the bottle body pushes the friction wheel to ascend to a designed position, at the moment, the driver drives the friction wheel to rotate, the friction wheel drives the bottle body to rotate, and in the rotation process, collection of a plurality of image data of the bottle body is completed through the image collection part; compared with the prior art, the friction wheel of the scheme can be pressed and lifted by the friction wheel after the bottle body is just jacked by a small distance, the detected bottle body is guaranteed to be limited in the triangular space surrounded by the friction wheel and the two guide wheels in most of jacking strokes, and the probability that the bottle body drops in the jacking process is greatly reduced. And after bottle image data acquisition is accomplished, the lift seat descends, and the friction pulley also descends thereupon this moment, and the in-process that descends, the friction pulley falls together with the bottle, has carried out the push down to the bottle from the top of bottle in other words, has alleviated the weightlessness degree of bottle, has reduced the probability that the bottle falls the in-process and drops easily.

Compared with the first embodiment, the present embodiment further has the following functions:

firstly, the method comprises the following steps: when the lifting seat 31 drives the bottle body to ascend, the ejector rod 36 also ascends along with the lifting seat 31 synchronously, after the bottle body is contacted with the friction wheel 33, the ejector rod 36 also props the height adjusting rod 37 on the vertical sliding frame 34, so that the ascending force of the vertical sliding frame 34 and the friction wheel 33 is mainly from the ejector rod 36, and the problem that the bottle body is deformed or cracked due to overlarge pressure of the friction wheel 33 and the vertical sliding frame 34 is avoided (the deformation can be greatly reduced or even avoided for the soft and easily deformed bottle body, and for the very fragile bottle body, such as a glass bottle, the problem of cracking of the bottle body can be avoided).

Secondly, the method comprises the following steps: due to the arrangement of the height adjusting rod 37 on the vertical sliding frame 34, the minimum distance between the guide wheel 32 and the friction wheel 33 on the lifting seat 31 is adjusted by the height adjusting rod 37 to change, and the space generated by the distance between the friction wheel 33 and the guide wheel 32 is used for accommodating bottles, namely, the existence of the height adjusting rod 37 enables the detection device to adapt to the bottle detection requirements of different outer diameter specifications, and the practicability of the device is improved; meanwhile, the pressure of the friction wheel 33 on the bottle body can be adjusted through the adjustment of the height adjusting rod 37, so that the probability of deformation or fragmentation of the bottle body is reduced on the basis that the bottle body has enough friction force with the friction wheel 33. Under the condition that the detected bottle outer diameter does not change greatly, even if the maximum ascending stroke of the lifting seat 31 is not adjusted, the device can ensure that enough friction force exists between the friction wheel 33 and the bottle under the action of the first elastic part 38 so as to enable the bottle to rotate along with the friction wheel 33 (the first elastic part 38 always has the tendency of pulling the friction wheel 33 downwards, the pulling-down tendency gives the force of pressing the bottle by the friction wheel 33, and further ensures the friction force between the bottle and the bottle), and can also ensure that enough friction force exists between the friction wheel 33 and the driving wheel 35 so as to enable the friction wheel 33 to rotate along with the driving wheel 35 under the action of the second elastic part 41 (the second elastic part 41 always has the tendency of tensioning the driving wheel 35 towards the direction of the friction wheel 33, the tendency gives the force of pressing the driving wheel 35 against the friction wheel 33, and further ensures the friction force between the bottle and the bottle), after the small-size change is ensured, the height of the bottle size can be detected by correspondingly adjusting the height of the height adjusting rod 37, and the whole mode is simple and convenient to operate.

Thirdly, the method comprises the following steps: when the detected bottle body outer diameter specification changes greatly, the detection requirement of the bottle body with the new specification can be met by adjusting the maximum jacking stroke of the lifting seat 31; also can be under the unchangeable condition of the biggest stroke of lifting seat 31 jacking (then the highest position of friction pulley 33 takes place to debate), through screwing up interval adjustment pole 42 with the minimum interval of adjustment action wheel 35 and friction pulley 33, perhaps adjustment height adjusting pole 37 is with the interval between adjustment guide pulley 32 and the friction pulley 33, and then guarantee that friction pulley 33 still can be supported tightly by action wheel 35 and drive the rotation of friction pulley 33 by action wheel 35, also can guarantee the detection demand of new specification bottle, and this kind of regulative mode is also very simple and convenient.
